System Interactions in Animals Tools Finish System Interactions in Animals The human body is made of many different organ systems. Each system performs unique functions for the body, but the systems also interact with each other to perform more complex functions. Major Organ Systems Body Systems In humans, cells, tissues, and organs group together to form organ systems. These systems each perform different functions for the human body. The major organ systems and their functions in humans include: The Nervous System — The nervous systems consists of two parts. The central nervous system consists of the brain and spinal cord, while the peripheral nervous system consists of nerves that connect the central nervous system to other parts of the body. The brain plays an important role in interpreting the information picked up by the sensory system. It helps in producing a precise response to the stimuli. It also controls bodily functions such as movements, thoughts, speech, and memory. The brain also controls many processes related to homeostasis in the body. The spinal cord connects to the brain through the brainstem. From the brainstem, the spinal cord extends to all the major nerves in the body. The spinal cord is the origin of spinal nerves that branch out to various body parts. These nerves help in receiving and transmitting signals from various body parts. The spinal cord helps in reflex actions of the body The smallest unit of the nervous system is the nerve cell, or neuron. Neurons communicate with each other and with other cells by producing and releasing electrochemical signals known as nerve impulses. Neurons consist of the cell body, the dendrites, and the axon. The cell body consists of a nucleus and cytoplasm. Dendrites are specialized branch-like structures that help in conducting impulses to and from the various body parts. Axons are long, slender extensions of the neuron. Each neuron possesses just a single axon. Its function is to carry the impulses away from the cell body to other neurons. The Circulatory System — The circulatory (or cardiovascular) system is composed of the heart, arteries, veins, and capillaries. The circulatory system is responsible for transporting blood to and from the lungs so that gas exchange can take place. As the circulatory system pumps blood throughout the body, dissolved nutrients and wastes are also delivered to their destinations. The heart is a muscular organ roughly the size of an adult human's closed fist. It is present behind the breastbone, slightly to the left. It consists of four chambers: right atrium, left atrium, right ventricle, and left ventricle. The heart receives deoxygenated blood from the body and pumps this blood to the lugs, where it is oxygenated. The oxygen-rich blood reenters the heart and is then pumped back through the body. The circulatory system is responsible for transporting blood to and from the lungs so that gas exchange can take place. As the circulatory system pumps blood throughout the body, dissolved nutrients and wastes are also delivered to their destinations. Blood circulation takes place through blood vessels. Blood vessels are tubular structures that form a network within the body and transport blood to each tissue. There are three major types of blood vessels: veins, arteries, and capillaries. Veins carry deoxygenated blood from the body to the heart, except for pulmonary veins, which carry oxygenated blood from the lungs to the heart. Arteries carry oxygenated blood from the heart to different organs, except for the pulmonary artery, which carries deoxygenated blood from the heart to the lungs. The arteries branch out to form capillaries. These capillaries are thin-walled vessels through which nutrients and wastes are exchanged with cells. The Respiratory System — The main structures of the respiratory system are the trachea (windpipe), the lungs, and the diaphragm. When the diaphragm contracts, it creates a vacuum in the lungs that causes them to fill with air. During this inhalation, oxygen diffuses into the circulatory system while carbon dioxide diffuses out into the air that will be exhaled. The trachea branches out into two primary bronchi. Each bronchus is further divided into numerous secondary bronchi. These secondary bronchi further branch into tertiary bronchi. Finally, each tertiary bronchus branches into numerous bronchioles. Each bronchiole terminates into a tiny, sac-like structure known as an alveolus. The walls of each alveolus are thin and contain numerous blood capillaries. The process of gaseous exchange occurs in these alveoli. The diaphragm is a dome-shaped muscle situated at the lower end of the rib cage. It separates the abdominal cavity from the chest cavity. During inhalation, the diaphragm contracts, and the chest cavity enlarges, creating a vacuum that allows air to be drawn in. This causes the alveoli in the lungs to expand with air. During this process, oxygen diffuses into the circulatory system while carbon dioxide diffuses out into the air that will be exhaled. On the other hand, expansion of the diaphragm causes exhalation of air containing carbon dioxide. The Digestive System — The digestive system consists of the mouth, stomach, small intestine, large intestine, and anus. It is responsible for taking in food, digesting it to extract energy and nutrients that cells can use to function, and expelling the remaining waste material. Mechanical and chemical digestion takes place in the mouth and stomach, while absorption of nutrients and water takes place in the intestines. The digestive system begins at the mouth, where food is taken in, and ends at the anus, where waste is expelled. The food taken into the mouth breaks into pieces by the grinding action of the teeth. Carbohydrate digestion starts in the mouth with the breakdown of carbohydrates into simple sugars with the help of salivary enzymes. The chewed food, known as a bolus, enters the stomach through the esophagus. The bolus mixes with acids and enzymes released by the stomach. Protein digestion starts in the stomach as proteins are broken down into peptides. This partially digested food is known as chyme. Chyme enters the small intestine and mixes with bile, a substance secreted by the liver, along with enzymes secreted by the pancreas. The digestion of fats starts in the small intestine as bile and pancreatic enzymes break down fats into fatty acids. The surface of the small intestine consists of hair-like projections known as villi. These villi help in absorbing nutrients from the digested food. The digested food enters the large intestine, or colon, where water and salts are reabsorbed. Any undigested food is expelled out of the body as waste. The Skeletal System — The skeletal system is made up of over 200 bones. It protects the body's internal organs, provides support for the body and gives it shape, and works with the muscular system to move the body. In addition, bones can store calcium and produce red and white blood cells. The Muscular System — The muscular system includes more than 650 tough, elastic pieces of tissue. The primary function of any muscle tissue is movement. This includes the movement of blood through the arteries, the movement of food through the digestive tract, and the movement of arms and legs through space. Skeletal muscles relax and contract to move the bones of the skeletal system. The Excretory System — The excretory system removes excess water, dangerous substances, and wastes from the body. The excretory system also plays an important role in maintaining body equilibrium, or homeostasis. The human excretory system includes the lungs, sweat glands in the skin, and the urinary system (such as the kidneys and the bladder). The body uses oxygen for metabolic processes. Oxygen metabolism results in the production of carbon dioxide, which is a waste matter. The lungs expel carbon dioxide through the mouth and nose. The liver converts toxic metabolic wastes, such as ammonia, into less harmful susbtances. Ammonia is converted to urea, which is then excreted in the urine. The skin also expels urea and small amounts of ammonia through sweat. The skin is embedded with sweat glands. These glands secrete sweat, a solution of water, salt, and wastes. The sweat rises to the skin's surface, where it evaporates. The skin maintains homeostasis by producing sweat in hot environments. Sweat production cools and prevents excessive heating of the body. Each kidney contains about a million tiny structures called nephrons, which filter the blood and collect waste products, such as urea, salts, and excess water that go on to become urine. The Endocrine System — The endocrine system is involved with the control of body processes such as fluid balance, growth, and sexual development. The endocrine system controls these processes through hormones, which are produced by endocrine glands. Some endocrine glands include the pituitary gland, thyroid gland, parathyroid gland, adrenal glands, thymus gland, ovaries in females, and testes in males. The Immune System — The immune system is a network of cells, tissues, and organs that defends the body against foreign invaders. The immune system uses antibodies and specialized cells, such as T-cells, to defend the body from microorganisms that cause disease. The Reproductive System — The reproductive system includes structures, such as the uterus and fallopian tubes in females and the penis and testes in males, that allow humans to produce new offspring. The reproductive system also controls certain hormones in the human body that regulate the development of sexual characteristics and determine when the body is able to reproduce. The Integumentary System — The integumentary system is made up of a person's skin, hair, and nails. The skin acts as a barrier to the outside world by keeping moisture in the body and foreign substances out of the body. Nerves in the skin act as an interface with the outside world, helping to regulate important aspects of homeostasis, such as body temperature. Interacting Organ Systems The organ systems work together to perform complex bodily functions. The functions of regulation, nutrient absorption, defense, and reproduction are only possible because of the interaction of multiple body systems. Regulation All living organisms must maintain homeostasis, a stable internal environment. Organisms maintain homeostasis by monitoring internal conditions and making adjustments to the body systems as necessary. For example, as body temperature increases, skin receptors and receptors in a region of the brain called the hypothalamus sense the change. The change triggers the nervous system to send signals to the integumentary and circulatory systems. These signals cause the skin to sweat and blood vessels close to the surface of the skin to dilate, actions which dispel heat to decrease body temperature. Both the nervous system and the endocrine system are typically involved in the maintenance of homeostasis. The nervous system receives and processes stimuli, and then it sends signals to body structures to coordinate a response. The endocrine system helps regulate the response through the release of hormones, which travel through the circulatory system to their site of action. For example, the endocrine system regulates the level of sugar in the blood by the release of the hormones insulin, which stimulates uptake of glucose by cells, and glucagon, which stimulates the release of glucose by the liver. The nervous and endocrine systems interact with the excretory system in the process of osmoregulation, the homeostatic regulation of water and fluid balance in the body. The excretory system expels excess water, salts, and waste products. The excretion of excessive amounts of water can be harmful to the body because it reduces blood pressure. If the nervous system detects a decrease in blood pressure, it stimulates the endocrine system to release antidiuretic hormone. This hormone decreases the amount of water released by the kidneys to ensure appropriate blood pressure. Appropriate levels of carbon dioxide in the blood are also maintained by homeostatic mechanisms that involve several organ systems. Excess carbon dioxide, a byproduct of cellular respiration, can be harmful to an organism. As blood circulates throughout the body, it picks up carbon dioxide waste from cells and transports it to the lungs, where it is exhaled while fresh oxygen is inhaled. If the concentration of carbon dioxide in the blood increases above a certain threshold, the nervous system directs the lungs to increase their respiration rate to remove the excess carbon dioxide, which ensures that the levels of carbon dioxide in the blood are maintained at appropriate levels. In this way, the circulatory, respiratory, and nervous systems work together to limit the level of carbon dioxide in the blood. Nutrient Absorption To absorb nutrients from food, the nervous, digestive, muscular, excretory, and circulatory systems all interact. The nervous system controls the intake of food and regulates the muscular action of chewing, which mechanically breaks down food. As food travels through the stomach and intestines, the digestive system structures release enzymes to stimulate its chemical breakdown. At the same time, the muscular action, called peristalsis, of the muscles in the wall of the stomach help churn the food and push it through the digestive tract. In the intestines, nutrients from food travel across the surfaces of the villi. The nutrients are then picked up by the blood, and the circulatory system transports the nutrients throughout the cells of the body. The endocrine system releases hormones, such as insulin, that control the rate at which certain body cells use nutrients. Any excess minerals, such as calcium, in the blood are deposited in and stored by the skeletal system. Waste products produced by the use of nutrients, as well as the leftover solid waste from the digestion of food, exit the body through the excretory system. Throughout the process of nutrient absorption, the nervous system controls the muscles involved in digestion, circulation, and excretion. Defense Several body systems interact to defend the body from external threats. The body's first line of defense is the integumentary system, which provide a physical barrier that prevents pathogens from entering the body. The skin of the integumentary system also contains receptors for pain, temperature, and pressure. If an unpleasant stimulus is encountered, these receptors send signals to the central nervous system. In response, the central nervous system sends commands to the muscles to move the body part away from the stimulus. In this way, the integumentary, nervous, and muscular systems interact to prevent damage to the body. In the event of a break in the skin, the nervous, immune, lymphatic, and circulatory systems work together to repair the wound and protect the body from pathogens. When the skin is broken, specialized blood cells called platelets form a clot to stop the bleeding. These platelets also release chemicals that travel through the circulatory system and recruit cells, like immune system cells, to repair the wound. These immune cells, or white blood cells, are transported by the circulatory and lymphatic systems to the site of the wound, where they identify and destroy potentially pathogenic cells to prevent an infection. Some lymphocytes, white blood cells produced by the lymphatic system, also produce antibodies to neutralize specific pathogens. All of the white blood cells involved in the body's response were originally produced in the bone marrow of the skeletal system. If an infection does occur

Diffusion (adolescent development) Stage of adolescent identity development where no commitments are made to identity Foreclosure (adolescent development) Stage of adolescent identity development where commitments are made to identity without first an exploration Moratorium (adolescent development) Stage of adolescent identity development where they are actively engaged in identity exploration racial and ethnic identity the sense of membership in a racial or ethnic group and the feelings that are associated with that membership Sexual orientation an enduring sexual attraction toward members of either one's own sex (homosexual orientation) or the other sex (heterosexual orientation) Religious identity a sense of belonging to a religious group Occupational identity Occupations that we engage in define who we are Familial identity the sense of self as always connected to family and others Possible selves images of what we dream of or dread becoming in the future Behavioral perspective An approach to the study of psychology that focuses on the role of learning in explaining observable behavior. Classical conditioning a type of learning in which one learns to link two or more stimuli and anticipate events Association any connection between thoughts, feelings, or experiences that leads one to recall another Acquisition In classical conditioning, the initial stage, when one links a neutral stimulus and an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response. In operant conditioning, the strengthening of a reinforced response. Associative learning learning that certain events occur together. The events may be two stimuli (as in classical conditioning) or a response and its consequences (as in operant conditioning). Unconditioned stimulus (US) in classical conditioning, a stimulus that naturally and automatically triggers a response. Unconditioned response (UR) In classical conditioning, the unlearned, naturally occurring response to the unconditioned stimulus (US), such as salivation when food is in the mouth. Conditioned response (CR) in classical conditioning, the learned response to a previously neutral (but now conditioned) stimulus (CS) Conditioned Stimulus (CS) in classical conditioning, an originally irrelevant stimulus that, after association with an unconditioned stimulus, comes to trigger a conditioned response Extinction the diminishing of a conditioned response; occurs in classical conditioning when an unconditioned stimulus (US) does not follow a conditioned stimulus (CS); occurs in operant conditioning when a response is no longer reinforced. Spontaneous recovery the reappearance, after a pause, of an extinguished conditioned response Stimulus discrimination a differentiation between two similar stimuli when only one of them is consistently associated with the unconditioned stimulus stimulus generalization learning that occurs when stimuli that are similar but not identical to the conditioned stimulus produce the conditioned response Higher-order conditioning a procedure in which the conditioned stimulus in one conditioning experience is paired with a new neutral stimulus, creating a second (often weaker) conditioned stimulus. For example, an animal that has learned that a tone predicts food might then learn that a light predicts the tone and begin responding to the light alone. (Also called second-order conditioning.) Counterconditioning a behavior therapy procedure that uses classical conditioning to evoke new responses to stimuli that are triggering unwanted behaviors; includes exposure therapies and aversive conditioning Taste aversion a type of classical conditioning in which a previously desirable or neutral food comes to be perceived as repugnant because it is associated with negative stimulation One-trial conditioning when one pairing of CS and a US produces considerable learning Habituation decreasing responsiveness with repeated stimulation. As infants gain familiarity with repeated exposure to a visual stimulus, their interest wanes and they look away sooner. Operant conditioning a type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher Reinforcement in operant conditioning, any event that strengthens the behavior it follows Punishment an event that decreases the behavior that it follows Law of effect Thorndike's principle that behaviors followed by favorable consequences become more likely, and that behaviors followed by unfavorable consequences become less likely Positive reinforcement Increasing behaviors by presenting positive stimuli, such as food.Any stimulus that, when presented after a response, strengthens the response. Negative reinforcement Increasing behaviors by stopping or reducing negative stimuli, such as shock. Any stimulus that, when removed after a response, strengthens the response. (Note: negative reinforcement is not punishment.) Primary reinforcers Events that are inherently reinforcing because they satisfy biological needs Secondary reinforcers learned reinforcers, such as money, that develop their reinforcing properties because of their association with primary reinforcers Shaping an operant conditioning procedure in which reinforcers guide behavior toward closer and closer approximations of the desired behavior Instinctive drift the tendency of learned behavior to gradually revert to biologically predisposed patterns Superstitious behavior a behavior repeated because it seems to produce reinforcement, even though it is actually unnecessary Learned helplessness the hopelessness and passive resignation an animal or human learns when unable to avoid repeated aversive events Reinforcement schedule a pattern that defines how often a desired response will be reinforced fixed interval reinforcement A form of partial reinforcement where rewards are provided after a specific time interval has passed after a response Fixed ratio reinforcement reinforces a response only after a specified number of responses Variable ratio reinforcement A form of partial reinforcement where rewards are provided after an unpredictable number of responses Scalloped graph The graphed pattern of a fixed interval reinforcement schedule Social learning theory the theory that we learn social behavior by observing and imitating and by being rewarded or punished Vicarious conditioning classical conditioning of a reflex response or emotion by watching the reaction of another person Modeling learning by imitating others; copying behavior Insight learning The process of learning how to solve a problem or do something new by applying what is already known Latent learning learning that occurs but is not apparent until there is an incentive to demonstrate it Cognitive maps An internal representation of the spatial relationships between objects in an animal's surroundings.

Classical conditioning a type of learning in which one learns to link two or more stimuli and anticipate events Association any connection between thoughts, feelings, or experiences that leads one to recall another Acquisition In classical conditioning, the initial stage, when one links a neutral stimulus and an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response. In operant conditioning, the strengthening of a reinforced response. Associative learning learning that certain events occur together. The events may be two stimuli (as in classical conditioning) or a response and its consequences (as in operant conditioning). Unconditioned stimulus (US) in classical conditioning, a stimulus that naturally and automatically triggers a response. Unconditioned response (UR) In classical conditioning, the unlearned, naturally occurring response to the unconditioned stimulus (US), such as salivation when food is in the mouth. Conditioned response (CR) in classical conditioning, the learned response to a previously neutral (but now conditioned) stimulus (CS) Conditioned Stimulus (CS) in classical conditioning, an originally irrelevant stimulus that, after association with an unconditioned stimulus, comes to trigger a conditioned response Extinction the diminishing of a conditioned response; occurs in classical conditioning when an unconditioned stimulus (US) does not follow a conditioned stimulus (CS); occurs in operant conditioning when a response is no longer reinforced. Spontaneous recovery the reappearance, after a pause, of an extinguished conditioned response Stimulus discrimination a differentiation between two similar stimuli when only one of them is consistently associated with the unconditioned stimulus stimulus generalization learning that occurs when stimuli that are similar but not identical to the conditioned stimulus produce the conditioned response Higher-order conditioning a procedure in which the conditioned stimulus in one conditioning experience is paired with a new neutral stimulus, creating a second (often weaker) conditioned stimulus. For example, an animal that has learned that a tone predicts food might then learn that a light predicts the tone and begin responding to the light alone. (Also called second-order conditioning.) Counterconditioning a behavior therapy procedure that uses classical conditioning to evoke new responses to stimuli that are triggering unwanted behaviors; includes exposure therapies and aversive conditioning Taste aversion a type of classical conditioning in which a previously desirable or neutral food comes to be perceived as repugnant because it is associated with negative stimulation One-trial conditioning when one pairing of CS and a US produces considerable learning Habituation decreasing responsiveness with repeated stimulation. As infants gain familiarity with repeated exposure to a visual stimulus, their interest wanes and they look away sooner. Operant conditioning a type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher Reinforcement in operant conditioning, any event that strengthens the behavior it follows Punishment an event that decreases the behavior that it follows Law of effect Thorndike's principle that behaviors followed by favorable consequences become more likely, and that behaviors followed by unfavorable consequences become less likely Positive reinforcement Increasing behaviors by presenting positive stimuli, such as food.Any stimulus that, when presented after a response, strengthens the response. Negative reinforcement Increasing behaviors by stopping or reducing negative stimuli, such as shock. Any stimulus that, when removed after a response, strengthens the response. (Note: negative reinforcement is not punishment.) Primary reinforcers Events that are inherently reinforcing because they satisfy biological needs Secondary reinforcers learned reinforcers, such as money, that develop their reinforcing properties because of their association with primary reinforcers Shaping an operant conditioning procedure in which reinforcers guide behavior toward closer and closer approximations of the desired behavior Instinctive drift the tendency of learned behavior to gradually revert to biologically predisposed patterns Superstitious behavior a behavior repeated because it seems to produce reinforcement, even though it is actually unnecessary Learned helplessness the hopelessness and passive resignation an animal or human learns when unable to avoid repeated aversive events Reinforcement schedule a pattern that defines how often a desired response will be reinforced fixed interval reinforcement A form of partial reinforcement where rewards are provided after a specific time interval has passed after a response Fixed ratio reinforcement reinforces a response only after a specified number of responses Variable ratio reinforcement A form of partial reinforcement where rewards are provided after an unpredictable number of responses Scalloped graph The graphed pattern of a fixed interval reinforcement schedule Social learning theory the theory that we learn social behavior by observing and imitating and by being rewarded or punished Vicarious conditioning classical conditioning of a reflex response or emotion by watching the reaction of another person Modeling learning by imitating others; copying behavior Insight learning The process of learning how to solve a problem or do something new by applying what is already known Latent learning learning that occurs but is not apparent until there is an incentive to demonstrate it Cognitive maps An internal representation of the spatial relationships between objects in an animal's surroundings.

Chapter 6: Adolescence Growth in Adolescence Puberty is a period of rapid growth and sexual maturation. These changes begin sometime l between eight and fourteen. Girls begin puberty at around ten years of age and boys begin approximately two years later. Pubertal changes take around three to four years to complete. Adolescents experience an overall physical growth spurt. The growth proceeds from the extremities toward the torso. This is referred to as distalproximal development. First the hands grow, then the arms, hand finally the torso. The overall physical growth spurt results in 10-11 inches of added height and 50 to 75 pounds of increased weight. The head begins to grow sometime after the feet have gone through their period of growth. Growth of the head is preceded by growth of the ears, nose, and lips. The difference in these patterns of growth result in adolescents appearing awkward and out-of-proportion. As the torso grows, so do the internal organs. The heart and lungs experience dramatic growth during this period. During childhood, boys and girls are quite similar in height and weight. However, gender differences become apparent during adolescence. From approximately age ten to fourteen, the average girl is taller, but not heavier, than the average boy. After that, the average boy becomes 223 both taller and heavier, although individual differences are certainly noted. As adolescents physically mature, weight differences are more noteworthy than height differences. At eighteen years of age, those that are heaviest weigh almost twice as much as the lightest, but the tallest teens are only about 10% taller than the shortest (Seifert, 2012). Both height and weight can certainly be sensitive issues for some teenagers. Most modern societies, and the teenagers in them, tend to favor relatively short women and tall men, as well as a somewhat thin body build, especially for girls and women. Yet, neither socially preferred height nor thinness is the destiny for many individuals. Being overweight, in particular, has become a common, serious problem in modern society due to the prevalence of diets high in fat and lifestyles low in activity (Tartamella et al., 2004). The educational system has, unfortunately, contributed to the problem as well by gradually restricting the number of physical education courses and classes in the past two decades. Average height and weight are also related somewhat to racial and ethnic background. In general, children of Asian background tend to be slightly shorter than children of European and North American background. The latter in turn tend to be shorter than children from African societies (Eveleth & Tanner, 1990). Body shape differs slightly as well, though the differences are not always visible until after puberty. Asian background youth tend to have arms and legs that are a bit short relative to their torsos, and African background youth tend to have relatively long arms and legs. The differences are only averages, as there are large individual differences as well. Sexual Development Typically, the growth spurt is followed by the development of sexual maturity. Sexual changes are divided into two categories: Primary sexual characteristics and secondary sexual characteristics. Primary sexual characteristics are changes in the reproductive organs. For males, this includes growth of the testes, penis, scrotum, and spermarche or first ejaculation of semen. This occurs between 11 and 15 years of age. For females, primary characteristics include growth of the uterus and menarche or the first menstrual period. The female gametes, which are stored in the ovaries, are present at birth, but are immature. Each ovary contains about 400,000 gametes, but only 500 will become mature eggs (Crooks & Baur, 2007). Beginning at puberty, one ovum ripens and is released about every 28 days during the menstrual cycle. Stress and higher percentage of body fat can bring menstruation at younger ages. Male Anatomy: Males have both internal and external genitalia that are responsible for procreation and sexual intercourse. Males produce their sperm on a cycle, and unlike the female's ovulation cycle, the male sperm production cycle is constantly producing millions of sperm daily. The main male sex organs are the penis and the testicles, the latter of which produce semen and sperm. The semen and sperm, as a result of sexual intercourse, can fertilize an ovum in the female's body; the fertilized ovum (zygote) develops into a fetus which is later born as a child. Female Anatomy: Female external genitalia is collectively known as the vulva, which includes the mons veneris, labia majora, labia minora, clitoris, vaginal opening, and urethral opening. Female internal reproductive organs consist of the vagina, uterus, fallopian tubes, and ovaries. The uterus hosts the developing fetus, produces vaginal and uterine secretions, and passes the male's sperm through to the fallopian tubes while the ovaries release the eggs. A female is born with all her eggs already produced. The vagina is attached to the uterus through the cervix, while the uterus is attached to the ovaries via the fallopian tubes. Females have a monthly reproductive cycle; at certain intervals the ovaries release an egg, which passes through the fallopian tube into the uterus. If, in this transit, it meets with sperm, the sperm might penetrate and merge with the egg, fertilizing it. If not fertilized, the egg is flushed out of the system through menstruation. Secondary sexual characteristics are visible physical changes not directly linked to reproduction but signal sexual maturity. For males this includes broader shoulders and a lower voice as the larynx grows. Hair becomes coarser and darker, and hair growth occurs in the pubic area, under the arms and on the face. For females, breast development occurs around age 10, although full development takes several years. Hips broaden, and pubic and underarm hair develops and also becomes darker and coarser. Acne: An unpleasant consequence of the hormonal changes in puberty is acne, defined as pimples on the skin due to overactive sebaceous (oil-producing) glands (Dolgin, 2011). These glands develop at a greater speed than the skin ducts that discharges the oil. Consequently, the ducts can become blocked with dead skin and acne will develop. According to the University of California at Los Angeles Medical Center (2000), approximately 85% of adolescents develop acne, and boys develop acne more than girls because of greater levels of testosterone in their systems (Dolgin, 2011). Experiencing acne can lead the adolescent to withdraw socially, especially if they are self-conscious about their skin or teased (Goodman, 2006). Effects of Pubertal Age: The age of puberty is getting younger for children throughout the world. According to Euling et al. (2008) data are sufficient to suggest a trend toward an earlier breast development onset and menarche in girls. A century ago the average age of a girl’s first period in the United States and Europe was 16, while today it is around 13. Because there is no clear marker of puberty for boys, it is harder to determine if boys are maturing earlier too. In addition to better nutrition, less positive reasons associated with early puberty for girls include increased stress, obesity, and endocrine disrupting chemicals. Cultural differences are noted with Asian-American girls, on average, developing last, while African American girls enter puberty the earliest. Hispanic girls start puberty the second earliest, while European-American girls rank third in their age of starting puberty. Although African American girls are typically the first to develop, they are less likely to experience negative consequences of early puberty when compared to European-American girls (Weir, 2016). Research has demonstrated mental health problems linked to children who begin puberty earlier than their peers. For girls, early puberty is associated with depression, substance use, eating disorders, disruptive behavior disorders, and early sexual behavior (Graber, 2013). Early maturing girls demonstrate more anxiety and less confidence in their relationships with family and friends, and they compare themselves more negatively to their peers (Weir, 2016). Problems with early puberty seem to be due to the mismatch between the child’s appearance and the way she acts and thinks. Adults especially may assume the child is more capable than she actually is, and parents might grant more freedom than the child’s age would indicate. For girls, the emphasis on physical attractiveness and sexuality is emphasized at puberty and they may lack effective coping strategies to deal with the attention they may receive. 226 Figure 6.4 Source Additionally, mental health problems are more likely to occur when the child is among the first in his or her peer group to develop. Because the preadolescent time is one of not wanting to appear different, early developing children stand out among their peer group and gravitate toward those who are older. For girls, this results in them interacting with older peers who engage in risky behaviors such as substance use and early sexual behavior (Weir, 2016). Boys also see changes in their emotional functioning at puberty. According to Mendle, Harden, Brooks-Gunn, and Graber (2010), while most boys experienced a decrease in depressive symptoms during puberty, boys who began puberty earlier and exhibited a rapid tempo, or a fast rate of change, actually increased in depressive symptoms. The effects of pubertal tempo were stronger than those of pubertal timing, suggesting that rapid pubertal change in boys may be a more important risk factor than the timing of development. In a further study to better analyze the reasons for this change, Mendle et al. (2012) found that both early maturing boys and rapidly maturing boys displayed decrements in the quality of their peer relationships as they moved into early adolescence, whereas boys with more typical timing and tempo development actually experienced improvements in peer relationships. The researchers concluded that the transition in peer relationships may be especially challenging for boys whose pubertal maturation differs significantly from those of others their age. Consequences for boys attaining early puberty were increased odds of cigarette, alcohol, or another drug use (Dudovitz, et al., 2015). Gender Role Intensification: At about the same time that puberty accentuates gender, role differences also accentuate for at least some teenagers. Some girls who excelled at math or science in elementary school, may curb their enthusiasm and displays of success at these subjects for fear of limiting their popularity or attractiveness as girls (Taylor et al/, 1995; Sadker, 2004). Some boys who were not especially interested in sports previously may begin dedicating themselves to athletics to affirm their masculinity in the eyes of others. Some boys and girls who once worked together successfully on class projects may no longer feel comfortable doing so, or alternatively may now seek to be working partners, but for social rather than academic reasons. Such changes do not affect all youngsters equally, nor affect any one youngster equally on all occasions. An individual may act like a young adult on one day, but more like a child the next. Adolescent Brain The brain undergoes dramatic changes during adolescence. Although it does not get larger, it matures by becoming more interconnected and specialized (Giedd, 2015). The myelination and 227 development of connections between neurons continues. This results in an increase in the white matter of the brain and allows the adolescent to make significant improvements in their thinking and processing skills. Different brain areas become myelinated at different times. For example, the brain’s language areas undergo myelination during the first 13 years. Completed insulation of the axons consolidates these language skills but makes it more difficult to learn a second language. With greater myelination, however, comes diminished plasticity as a myelin coating inhibits the growth of new connections (Dobbs, 2012). Even as the connections between neurons are strengthened, synaptic pruning occurs more than during childhood as the brain adapts to changes in the environment. This synaptic pruning causes the gray matter of the brain, or the cortex, to become thinner but more efficient (Dobbs, 2012). The corpus callosum, which connects the two hemispheres, continues to thicken allowing for stronger connections between brain areas. Additionally, the hippocampus becomes more strongly connected to the frontal lobes, allowing for greater integration of memory and experiences into our decision making. The limbic system, which regulates emotion and reward, is linked to the hormonal changes that occur at puberty. The limbic system is also related to novelty seeking and a shift toward interacting with peers. In contrast, the prefrontal cortex which is involved in the control of impulses, organization, planning, and making good decisions, does not fully develop until the mid-20s. According to Giedd (2015) the significant aspect of the later developing prefrontal cortex and early development of the limbic system is the “mismatch” in timing between the two. The approximately ten years that separates the development of these two brain areas can result in risky behavior, poor decision making, and weak emotional control for the adolescent. When puberty begins earlier, this mismatch extends even further. Teens often take more risks than adults and according to research it is because they weigh risks and rewards differently than adults do (Dobbs, 2012). For adolescents the brain’s sensitivity to the neurotransmitter dopamine peaks, and dopamine is involved in reward circuits, so the possible rewards outweighs the risks. Adolescents respond especially strongly to social rewards during activities, and they prefer the company of others their same age. Chein et al. (2011) found that peers sensitize brain regions associated with potential rewards. For example, adolescent drivers make risky driving decisions when with friends to impress them, and teens are much more likely to commit crimes together in comparison to adults (30 and older) who commit them alone (Steinberg et al., 2017). In addition to dopamine, the adolescent brain is affected by oxytocin which facilitates bonding and makes social connections more rewarding. With both dopamine and oxytocin engaged, it is no wonder that adolescents seek peers and excitement in their lives that could end up actually harming them. 228 Because of all the changes that occur in the adolescent brain, the chances for abnormal development can occur, including mental illness. In fact, 50% of the mental illness occurs by the age 14 and 75% occurs by age 24 (Giedd, 2015). Additionally, during this period of development the adolescent brain is especially vulnerable to damage from drug exposure. For example, repeated exposure to marijuana can affect cellular activity in the endocannabinoid system. Consequently, adolescents are more sensitive to the effects of repeated marijuana exposure (Weir, 2015). However, researchers have also focused on the highly adaptive qualities of the adolescent brain which allow the adolescent to move away from the family towards the outside world (Dobbs, 2012; Giedd, 2015). Novelty seeking and risk taking can generate positive outcomes including meeting new people and seeking out new situations. Separating from the family and moving into new relationships and different experiences are actually quite adaptive for society. Adolescent Sleep According to the National Sleep Foundation (NSF) (2016), adolescents need about 8 to 10 hours of sleep each night to function best. The most recent Sleep in America poll in 2006 indicated that adolescents between sixth and twelfth grade were not getting the recommended amount of sleep. On average adolescents only received 7 ½ hours of sleep per night on school nights with younger adolescents getting more than older ones (8.4 hours for sixth graders and only 6.9 hours for those in twelfth grade). For the older adolescents, only about one in ten (9%) get an optimal amount of sleep, and they are more likely to experience negative consequences the following day. These include feeling too tired or sleepy, being cranky or irritable, falling asleep in school, having a depressed mood, and drinking caffeinated beverages (NSF, 2016). Additionally, they are at risk for substance abuse, car crashes, poor academic performance, obesity, and a weakened immune system (Weintraub, 2016). Troxel et al. (2019) found that insufficient sleep in adolescents is a predictor of risky sexual behaviors. Reasons given for this include that those adolescents who stay out late, typically without parental supervision, are more likely to engage in a variety of risky behaviors, including risky sex, such as not using birth control or using substances before/during sex. An alternative explanation for risky sexual behavior is that the lack of sleep negatively affects impulsivity and decision-making processes. Figure 6.7 Source Why do adolescents not get adequate sleep? In addition to known environmental and social factors, including work, homework, media, technology, and socializing, the adolescent brain is also a factor. As adolescent go through puberty, their circadian rhythms change and push back their sleep time until later in the evening (Weintraub, 2016). This biological change not only keeps adolescents awake at night, it makes it difficult for them to wake up. When they are awake too early, their brains do not function optimally. Impairments are noted in attention, academic achievement, and behavior while increases in tardiness and absenteeism are also seen. 229 To support adolescents’ later sleeping schedule, the Centers for Disease Control and Prevention recommended that school not begin any earlier than 8:30 a.m. Unfortunately, over 80% of American schools begin their day earlier than 8:30 a.m. with an average start time of 8:03 a.m. (Weintraub, 2016). Psychologists and other professionals have been advocating for later school times, and they have produced research demonstrating better student outcomes for later start times. More middle and high schools have changed their start times to better reflect the sleep research. However, the logistics of changing start times and bus schedules are proving too difficult for some schools leaving many adolescent vulnerable to the negative consequences of sleep deprivation. Troxel et al. (2019) cautions that adolescents should find a middle ground between sleeping too little during the school week and too much during the weekends. Keeping consistent sleep schedules of too little sleep will result in sleep deprivation but oversleeping on weekends can affect the natural biological sleep cycle making it harder to sleep on weekdays. Adolescent Sexual Activity By about age ten or eleven, most children experience increased sexual attraction to others that affects social life, both in school and out (McClintock & Herdt, 1996). By the end of high school, more than half of boys and girls report having experienced sexual intercourse at least once, though it is hard to be certain of the proportion because of the sensitivity and privacy of the information. (Center for Disease Control, 2004; Rosenbaum, 2006). Adolescent Pregnancy: As can be seen in Figure 6.8, in 2018 females aged 15–19 years experienced a birth rate (live births) of 17.4 per 1,000 women. The birth rate for teenagers has declined by 58% since 2007 and 72% since 1991, the most recent peak (Hamilton, Joyce, Martin, & Osterman, 2019). It appears that adolescents seem to be less sexually active than in previous years, and those who are sexually active seem to be using birth control (CDC, 2016). Figure 6.8 Source Risk Factors for Adolescent Pregnancy: Miller et al. (2001) found that parent/child closeness, parental supervision, and parents' values against teen intercourse (or unprotected intercourse) decreased the risk of adolescent pregnancy. In contrast, residing in disorganized/dangerous neighborhoods, living in a lower SES family, living with a single parent, having older sexually 230 active siblings or pregnant/parenting teenage sisters, early puberty, and being a victim of sexual abuse place adolescents at an increased risk of adolescent pregnancy. Consequences of Adolescent Pregnancy: After the child is born life can be difficult for a teenage mother. Only 40% of teenagers who have children before age 18 graduate from high school. Without a high school degree her job prospects are limited, and economic independence is difficult. Teen mothers are more likely to live in poverty, and more than 75% of all unmarried teen mother receive public assistance within 5 years of the birth of their first child. Approximately, 64% of children born to an unmarried teenage high-school dropout live in poverty. Further, a child born to a teenage mother is 50% more likely to repeat a grade in school and is more likely to perform poorly on standardized tests and drop out before finishing high school (March of Dimes, 2012). Research analyzing the age that men father their first child and how far they complete their education have been summarized by the Pew Research Center (2015) and reflect the research for females. Among dads ages 22 to 44, 70% of those with less than a high school diploma say they fathered their first child before the age of 25. In comparison, less than half (45%) of fathers with some college experience became dads by that age. Additionally, becoming a young father occurs much less for those with a bachelor’s degree or higher as just 14% had their first child prior to age 25. Like men, women with more education are likely to be older when they become mothers. Eating Disorders Figure 6.9 According to the DSM-5-TR (American Psychiatric Association, 2022), eating disorders are characterized by a persistent disturbance of eating or eating-related behavior that results in the altered consumption or absorption of food and that significantly impairs physical health or psychosocial functioning. Although eating disorders can occur in children and adults, they frequently appear during the teen years or young adulthood (National Institute of Mental Health (NIMH), 2016). Eating disorders affect both genders, although rates among women are 2½ times greater than among men. Similar to women who have eating disorders, men also have a distorted sense of body image, including muscle dysmorphia, which is an extreme desire to increase one’s muscularity (Bosson et al., 2019). The prevalence of eating disorders in the United States is similar among Non-Hispanic Whites, Hispanics, African-Americans, and Asians, with the exception that anorexia nervosa is more common among Non-Hispanic Whites (Hudson et al., 2007; Wade et al., 2011). Source Risk Factors for Eating Disorders: Because of the high mortality rate, researchers are looking into the etiology of the disorder and associated risk factors. Researchers are finding that eating disorders are caused by a complex interaction of genetic, biological, behavioral, psychological, and social factors (NIMH, 2016). Eating disorders appear to run in families, and researchers are working to identify DNA variations that are linked to the increased risk of developing eating 231 disorders. Researchers from King’s College London (2019) found that the genetic basis of anorexia overlaps with both metabolic and body measurement traits. The genetic factors also influence physical activity, which may explain the high activity level of those with anorexia. Further, the genetic basis of anorexia overlaps with other psychiatric disorders. Researchers have also found differences in patterns of brain activity in women with eating disorders in comparison with healthy women. The main criteria for the most common eating disorders: Anorexia nervosa, bulimia nervosa, and binge-eating disorder are described in the DSM-5-TR (American Psychiatric Association, 2022) and listed in Table 6.1. Table 6.1 DSM-5-TR Eating Disorders Anorexia Nervosa  Restriction of energy intake leading to a significantly low body weight  Intense fear of gaining weight  Disturbance in one’s self-evaluation regarding body weight Bulimia Nervosa Binge-Eating Disorder  Recurrent episodes of binge eating  Recurrent inappropriate compensatory behaviors to prevent weight gain, including purging, laxatives, fasting or excessive exercise  Self-evaluation is unduly affected by body shape and weight  Recurrent episodes of binge eating  Marked distress regarding binge eating  The binge eating is not associated with the recurrent use of inappropriate compensatory behavior Health Consequences of Eating Disorders: For those suffering from anorexia, health consequences include an abnormally slow heart rate and low blood pressure, which increases the risk for heart failure. Additionally, there is a reduction in bone density (osteoporosis), muscle loss and weakness, severe dehydration, fainting, fatigue, and overall weakness. Anorexia nervosa has the highest mortality rate of any psychiatric disorder (Arcelus et al., 2011). Individuals with this disorder may die from complications associated with starvation, while others die of suicide. In women, suicide is much more common in those with anorexia than with most other mental disorders. The binge and purging cycle of bulimia can affect the digestives system and lead to electrolyte and chemical imbalances that can affect the heart and other major organs. Frequent vomiting can cause inflammation and possible rupture of the esophagus, as well as tooth decay and staining from stomach acids. Lastly, binge eating disorder results in similar health risks to obesity, including high blood pressure, high cholesterol levels, heart disease, Type II diabetes, and gall bladder disease (National Eating Disorders Association, 2016). 232 Figure 6.10 Source Eating Disorders Treatment: To treat eating disorders, adequate nutrition and stopping inappropriate behaviors, such as purging, are the foundations of treatment. Treatment plans are tailored to individual needs and include medical care, nutritional counseling, medications (such as antidepressants), and individual, group, and/or family psychotherapy (NIMH, 2016). For example, the Maudsley Approach has parents of adolescents with anorexia nervosa be actively involved in their child’s treatment, such as assuming responsibility for feeding the child. To eliminate binge eating and purging behaviors, cognitive behavioral therapy (CBT) assists sufferers by identifying distorted thinking patterns and changing inaccurate beliefs

SOCY 200 Human Societies Study Guide Dr. Swann - 2024 Spring Final The test will be very similar in format to the midterm but with 5 or 10 more questions likely. I will discuss the format further during class. This is a guide, not an exhaustive list. Concepts •Inequality- Understand the prevalence and impact of inequality along gender, racial, and sexual lines Gender Inequality: Economic Disparities: Women often earn less than men for the same work and are disproportionately represented in lower-paying jobs and industries. Political Underrepresentation: Women are often underrepresented in politics and leadership positions, affecting policy decisions and societal norms. Social Expectations and Stereotypes: Gender norms and stereotypes can limit opportunities and reinforce unequal power dynamics. Racial Inequality: Wealth Gap: Historical discrimination and systemic barriers have resulted in significant wealth disparities between racial groups. Criminal Justice System: Racial minorities, especially Black and Latino individuals, are disproportionately affected by police violence, mass incarceration, and harsher sentencing. Education: Schools in predominantly minority communities often lack resources and face systemic biases, leading to unequal educational outcomes. Sexual Orientation and Identity: Legal Discrimination: In many places, LGBTQ+ individuals face legal discrimination in areas such as employment, housing, and access to healthcare. Violence and Harassment: LGBTQ+ individuals are at a higher risk of experiencing violence, harassment, and discrimination, which can lead to mental health issues and social exclusion. Family Rights: Legal recognition and rights for same-sex couples and LGBTQ+ parents vary widely across regions, impacting their ability to access services and protections. •Media Influence- Understand the role and sphere of influence of the media o. How much do we consume and what do we consume o. What you watch affects your beliefs o. Trust in the media o. What the media shows/ discusses and what the media does not show/discuss How much do we consume and what do we consume: Media consumption has dramatically increased with the advent of digital technology and the internet. People spend significant amounts of time engaging with various forms of media, including television, radio, newspapers, websites, social media platforms, podcasts, and streaming services. The content consumed varies widely, ranging from news, entertainment, sports, educational material, to user-generated content. Preferences for specific types of content are influenced by individual interests, demographics, and cultural factors. What you watch affects your beliefs: Numerous studies have demonstrated the correlation between media exposure and beliefs, attitudes, and behaviors. The content we consume can shape our perceptions of the world, our understanding of social issues, and our attitudes towards different groups and cultures. Media representations of gender, race, ethnicity, and other social identities can influence stereotypes and perpetuate biases. Exposure to diverse and inclusive media can challenge these stereotypes and promote empathy and understanding. Trust in the media: Trust in traditional media sources has been declining in recent years, influenced by factors such as perceived bias, misinformation, sensationalism, and corporate ownership. Trust is crucial for the credibility and effectiveness of media organizations. Transparency, accuracy, accountability, and editorial independence are essential for building and maintaining trust with audiences. What the media shows/discusses and what the media does not show/discuss: Media outlets play a critical role in shaping public discourse by determining which issues receive attention and how they are framed. This process, known as agenda-setting, influences the public's perception of what is important and newsworthy. Media coverage can be influenced by various factors, including editorial priorities, commercial interests, political agendas, and audience preferences. Certain topics may receive extensive coverage, while others are overlooked or underreported. Media gatekeeping, where editors and producers decide which stories to prioritize, can contribute to the amplification or suppression of certain voices and perspectives. Lack of diversity in newsrooms can also lead to gaps in coverage and representation. •Social Media o. Impacts on society ▪Gen Z ▪Impacts on mental health •Specifically Gen Z Gen Z and Social Media: Gen Z is the first generation to grow up entirely in the digital age, making social media an integral part of their lives from a young age. Social media platforms serve as primary channels for communication, self-expression, entertainment, and socialization among Gen Z. They use platforms like Instagram, TikTok, Snapchat, and Twitter to connect with peers, share experiences, and explore their identities. Impact on Mental Health: Social media usage among Gen Z has been linked to various mental health challenges, including anxiety, depression, loneliness, and body image issues. Comparison: Social media often promotes unrealistic standards of beauty, success, and happiness, leading to feelings of inadequacy and low self-esteem among Gen Z users who compare themselves to curated and filtered images and lifestyles. Cyberbullying: Gen Z faces increased risks of cyberbullying and online harassment through social media platforms, which can have devastating effects on their mental health and well-being. Fear of Missing Out (FOMO): Gen Z's constant exposure to their peers' activities and experiences on social media can exacerbate feelings of FOMO, anxiety, and social isolation. Digital Addiction: Excessive use of social media can contribute to digital addiction, where Gen Z individuals find it challenging to disconnect from their devices and prioritize offline activities, leading to sleep disturbances, concentration difficulties, and overall diminished well-being. Addressing Mental Health Challenges: Some efforts are underway to address mental health challenges associated with social media use among Gen Z: Digital literacy programs and mental health education initiatives aim to empower Gen Z with the skills to critically evaluate online content, recognize harmful behaviors, and seek support when needed. Mental health advocates and organizations collaborate with social media platforms to implement safety features, anti-bullying measures, and resources for mental health support. Increased awareness and destigmatization of mental health issues help Gen Z feel more comfortable seeking help and support from trusted adults, peers, and mental health professionals. o. Prevalence and ubiquity ▪How quickly adopted/became normative Prevalence and Ubiquity: Social media platforms have become ubiquitous in contemporary society, with billions of users worldwide across various demographics. These platforms facilitate instant communication, content sharing, and community building, fundamentally altering how people connect, share information, and engage with each other. The prevalence of social media is evident in its integration into daily life activities, including personal relationships, work, education, entertainment, and even activism. Speed of Adoption: The adoption of social media occurred rapidly, driven by advances in technology, the proliferation of internet access, and changing cultural norms. Platforms like Facebook, launched in 2004, experienced exponential growth, reaching millions of users within a few years. Similarly, Twitter (2006), Instagram (2010), and Snapchat (2011) gained widespread popularity relatively quickly. The advent of smartphones and mobile apps further accelerated social media adoption, enabling users to access platforms anytime, anywhere, and fostering continuous engagement. Normative Status: Social media has transitioned from a novelty to a normative aspect of contemporary life, influencing social norms, behaviors, and expectations. It's now considered customary for individuals, businesses, organizations, and even governments to maintain a presence on social media platforms to communicate, engage with stakeholders, and stay relevant. Social media usage is normalized across generations, with younger demographics, such as Gen Z, incorporating it seamlessly into their daily routines and identity formation processes. •Immigrants -Understand the labeling of different waves and generations of immigrants and what these labels entail o. Where do most immigrants come from o. Periods of internal migration in the US o. Deportation Labeling of Immigrant Waves and Generations: First Wave: Refers to the initial period of significant immigration to the United States, primarily from European countries during the 19th and early 20th centuries. This wave included immigrants from Ireland, Germany, Italy, and Eastern European countries. Second Wave: This term is often used to describe the period of immigration that occurred after restrictive immigration laws were lifted in the mid-20th century. It includes immigrants from Latin America, Asia, and other regions, driven by factors such as labor demand, family reunification, and political instability. Third Wave: Sometimes referred to as contemporary immigration, this wave encompasses recent immigration trends, characterized by globalization, advancements in transportation, and changes in immigration policies. It includes immigrants from diverse backgrounds, including Asia, Africa, the Middle East, and Latin America. Where do most immigrants come from: Historically, immigrants to the United States have come from various regions around the world, depending on geopolitical events, economic conditions, and immigration policies. In recent years, the majority of immigrants to the United States have come from countries in Latin America, particularly Mexico, Central America, and the Caribbean, as well as from Asian countries such as China, India, the Philippines, and Vietnam. Periods of Internal Migration in the US: Internal migration within the United States has also played a significant role in shaping demographic patterns and regional development. Historical periods of internal migration include the westward expansion during the 19th century, the Great Migration of African Americans from the South to northern cities during the early to mid-20th century, and more recent trends of migration from rural to urban areas. Deportation: Deportation refers to the formal removal of immigrants from a country due to violations of immigration laws or other legal grounds. The United States has a long history of deportation, including periods of mass deportation, such as the Mexican Repatriation during the 1930s and the deportation of undocumented immigrants in recent years. Deportation policies and practices have been subject to debate and controversy, with concerns raised about due process, human rights, and the impact on families and communities. •Gender- Understand Socialized Gender Differences o. ‘Real’ differences between males and females ▪How those things play into the social construction of gender, gender stereotypes, and gender roles Biological Differences: Males and females do exhibit biological differences, including differences in reproductive anatomy, hormones, and certain physical characteristics. These differences are often related to reproductive functions and secondary sexual characteristics but do not fully account for the wide range of behaviors, traits, and capabilities exhibited by individuals of different genders. Social Construction of Gender: Gender is a socially constructed concept, meaning that the roles, behaviors, expectations, and identities associated with masculinity and femininity are shaped by cultural norms, beliefs, and institutions. Socialization begins at an early age and continues throughout life, with individuals learning and internalizing gender norms and expectations through interactions with family, peers, media, and other social institutions. Gender Stereotypes: Gender stereotypes are oversimplified, generalized beliefs about the characteristics, abilities, and behaviors of males and females. These stereotypes often perpetuate traditional notions of gender roles and reinforce inequality and discrimination. For example, stereotypes may dictate that males are assertive, strong, and rational, while females are nurturing, emotional, and submissive. These stereotypes can limit individuals' opportunities and perpetuate harmful gender norms. Gender Roles: Gender roles refer to the societal expectations and norms regarding the behaviors, responsibilities, and activities deemed appropriate for males and females. These roles can vary across cultures and historical contexts but often involve expectations related to caregiving, household duties, employment, and leadership. Gender roles are reinforced through socialization processes and institutions such as family, education, religion, and media, influencing individuals' self-concepts and behaviors. Interplay Between Biological and Social Factors: While biological differences may contribute to certain tendencies or predispositions, the social construction of gender significantly shapes how these differences are perceived, interpreted, and valued within society. For example, biological differences in strength or reproductive functions may influence the division of labor and social roles assigned to men and women, but societal expectations and cultural norms also play a crucial role in defining what is considered "appropriate" behavior for each gender. o. Understanding that most gendered differences are social ▪Leisure activities, desired jobs, self-care, willingness to ask for help, etc. Leisure Activities: Gender norms and expectations often influence the types of leisure activities individuals engage in. For example, sports may be more encouraged and accessible for boys, while girls may be steered towards activities perceived as more feminine, such as dance or art. These gendered leisure preferences can be shaped by socialization, media representations, peer influences, and parental expectations. Desired Jobs: Gender stereotypes and societal norms can influence individuals' career aspirations and choices. Certain professions may be seen as more suitable or desirable for men or women based on perceptions of gender roles and abilities. Women may face barriers or discouragement from pursuing careers in male-dominated fields such as STEM (Science, Technology, Engineering, and Mathematics), while men may encounter stigma or pressure for choosing traditionally female-dominated professions like nursing or teaching. Self-Care: Gendered expectations around self-care can impact how individuals prioritize their physical and emotional well-being. Women may be socialized to prioritize caregiving and nurturing roles, often at the expense of their own self-care needs. Men, on the other hand, may face societal pressures to prioritize stoicism and self-reliance, which can discourage seeking help for mental health issues or engaging in activities perceived as self-indulgent, such as therapy or self-care practices. Willingness to Ask for Help: Gender norms can influence individuals' attitudes towards seeking help and expressing vulnerability. Women may be socialized to be more comfortable seeking support and expressing emotions, while men may feel pressure to suppress vulnerability and handle challenges independently. These gendered expectations can impact help-seeking behaviors, mental health outcomes, and interpersonal relationships, contributing to disparities in access to support services and resources. o. Gender roles ▪Changing mom and dad roles •Women now expected to work •Increasing Age of 1st birth in America and across the world o. Explanations Changing Mom and Dad Roles: Traditionally, gender roles within families often assigned women the primary responsibility for caregiving and homemaking, while men were expected to be the primary breadwinners. However, societal shifts, including women's increasing education levels, workforce participation, and changing attitudes towards gender roles, have led to a reevaluation of these traditional roles. Women Expected to Work: Women's participation in the workforce has been steadily increasing over the past century, driven by factors such as economic necessity, greater educational opportunities, and changing social norms. As a result, women are no longer solely defined by their roles as caregivers and homemakers but are increasingly expected to pursue careers and contribute to household income. Increasing Age of First Birth: Across the United States and many other parts of the world, there has been a trend towards delaying the age of first birth. Several factors contribute to this trend, including: Education and Career Pursuits: As women pursue higher education and establish careers, they may delay starting a family to focus on personal and professional goals. Economic Factors: Financial stability and economic concerns play a significant role in family planning decisions. Many couples choose to delay having children until they feel financially secure. Access to Contraception and Family Planning Services: Increased access to contraception and family planning resources allows individuals more control over their reproductive choices, including when to have children. Cultural and Social Changes: Changing societal attitudes towards marriage, childbearing, and family dynamics also contribute to the trend of delaying parenthood. Explanations: The changing roles of moms and dads and the trend of delaying the age of first birth reflect broader shifts in societal norms, economic structures, and cultural expectations. These changes are driven by factors such as increased gender equality, greater access to education and career opportunities for women, and evolving attitudes towards family and parenthood. While these shifts represent progress towards more egalitarian and flexible gender roles, they also present challenges, including balancing work and family responsibilities, addressing childcare needs, and navigating societal expectations. •Decreasing family sizes across much of the world o. Hans Rosling Hans Rosling, a Swedish physician, academic, and statistician, was a prominent advocate for data-driven analysis and global health equity. He founded the Gapminder Foundation, which aims to promote a fact-based worldview through the innovative use of data visualization tools. Rosling's work often focused on challenging misconceptions and stereotypes about global development, population trends, and socio-economic disparities. One of the key topics he addressed was the phenomenon of decreasing family sizes across much of the world. Decreasing Family Sizes: Rosling emphasized that as societies undergo economic development and improvements in healthcare and education, fertility rates tend to decline. This decline in fertility rates is often attributed to factors such as increased access to contraception, higher levels of education for women, greater economic opportunities, and changes in cultural norms surrounding family planning. As families become more educated and economically stable, they often choose to have fewer children, prioritizing quality of life and investing more resources in each child's education and well-being. Rosling's work helped debunk myths and misconceptions about population growth, illustrating that global fertility rates were decreasing rather than increasing. He highlighted the importance of accurate data and evidence-based analysis in understanding complex global trends and informing policy decisions. o. Performing Gender o. F*g Discourse/ Self-policing ▪CJ Pascoe o. Changes in notions of gender ▪Specifically among Gen Z Performing gender refers to how individuals enact and express their gender identity through behaviors, appearances, and interactions, often influenced by societal norms and expectations. Here's an exploration of f*g discourse and self-policing, as well as changes in notions of gender, particularly among Gen Z: F*g Discourse/Self-policing: F*g discourse refers to derogatory language and derogatory labeling used to police and stigmatize individuals who deviate from traditional gender norms, particularly masculinity norms. CJ Pascoe, a sociologist, conducted research on masculinity and gender among adolescent boys, particularly focusing on how boys engage in f*g discourse and self-policing behaviors to assert and maintain their masculine identities. Pascoe's work highlighted how boys use homophobic language and behaviors to reinforce masculinity norms, establish social hierarchies, and police each other's gender performances. This self-policing can create pressure for conformity and marginalize individuals who do not conform to dominant gender expectations. Changes in Notions of Gender, Specifically Among Gen Z: Gen Z is often characterized by its greater openness and acceptance of diverse gender identities and expressions compared to previous generations. Gen Z individuals are more likely to challenge traditional binary notions of gender and embrace a spectrum of gender identities beyond the male-female binary. Social media and online communities have played a significant role in facilitating conversations around gender diversity and providing platforms for individuals to express their authentic selves. Gen Z's attitudes towards gender reflect broader cultural shifts towards greater acceptance and inclusivity, challenging stereotypes and norms that limit expression and self-discovery. •Race- Understand the social construction of race and historical narratives and changes o. Racial formation ▪Omi and Winant Racial Formation: Omi and Winant argue that race is not a fixed, biological category but rather a social construct that is continually produced and contested within specific historical and social contexts. They emphasize that race is a dynamic and relational concept, shaped by power dynamics, ideologies, institutions, and cultural representations. Racial formation involves the articulation of racial meanings, the institutionalization of racial practices, and the mobilization of racial groups in pursuit of their interests. Key Concepts: Racial Projects: Omi and Winant introduce the concept of racial projects, which are coordinated efforts by individuals, groups, and institutions to define and organize racial categories and relations. Racial projects can take various forms, including policies, laws, discourses, and cultural representations. Racialization: Racialization refers to the process through which social groups are categorized and marked by race, attributing certain characteristics, statuses, and meanings to them. Racialization can occur through explicit policies, implicit biases, and cultural stereotypes. Racial Formation Regimes: Omi and Winant analyze racial formation as a complex system of racial categories, hierarchies, and ideologies that shape social relations and institutions. Racial formation regimes encompass the historical and structural dimensions of racial dynamics within society. Historical Narratives and Changes: Omi and Winant's framework helps to understand the historical narratives and changes in racial dynamics in the United States and beyond. It highlights how racial categories and meanings have been constructed, contested, and transformed over time through processes of colonization, slavery, immigration, segregation, and globalization. For example, the shift from explicit forms of racial segregation to more subtle forms of racial inequality and discrimination reflects changes in racial formations and ideologies. Historical events such as the Civil Rights Movement, immigration waves, and globalization have also influenced racial formations, challenging existing racial hierarchies and identities while also generating new forms of racialization and social conflict. o. Racism ▪Implicit v explicit ▪Structural v personal Implicit vs. Explicit Racism: Explicit Racism: Explicit racism refers to overt, conscious expressions of racial prejudice and discrimination. This can include acts such as racial slurs, hate speech, hate crimes, and discriminatory practices based on race. Examples of explicit racism include racially motivated violence, discriminatory hiring practices, segregationist policies, and hate groups advocating for racial superiority. Implicit Racism: Implicit racism refers to unconscious biases, attitudes, and stereotypes that influence behavior and decision-making, often without individuals being aware of it. These biases can manifest in subtle ways, such as microaggressions, implicit biases in hiring and promotion decisions, and differential treatment based on race in various social contexts. Implicit racism can be perpetuated through cultural stereotypes, media representations, and socialization processes, leading to systemic inequalities and disparities. Structural vs. Personal Racism: Structural Racism: Structural racism refers to how societal institutions, policies, and practices perpetuate racial inequalities and disparities, often regardless of individual intent or prejudice. Structural racism operates at the systemic level, shaping access to resources, opportunities, and power based on race. It is embedded within social, political, economic, and cultural systems. Examples of structural racism include disparities in education, housing, healthcare, employment, criminal justice, and representation in positions of power. Personal Racism: Personal racism involves individual attitudes, beliefs, and actions that perpetuate racial prejudice, discrimination, and bias. This can include acts of overt discrimination, implicit biases, racial stereotypes, and microaggressions perpetrated by individuals in interpersonal interactions. While personal racism is often influenced by broader social structures and cultural norms, it operates at the level of individual behavior and attitudes. o. Inequality by race o. Criminal justice differences Inequality by race in the criminal justice system is a complex and longstanding issue that encompasses disparities at various stages of the criminal justice process. Here's an overview of some key aspects: 1. Policing: Racial profiling: Minority individuals, particularly Black and Hispanic individuals, are disproportionately targeted for stops, searches, and arrests by law enforcement agencies based on their race or ethnicity, rather than evidence of criminal activity. Use of force: Black individuals are more likely to experience police use of force, including deadly force, compared to their White counterparts, leading to higher rates of injury and death among Black communities. 2. Arrests and Charging: Disproportionate arrests: Black and Hispanic individuals are overrepresented in arrest statistics for various offenses, including drug-related offenses, despite similar rates of drug use across racial groups. Charging decisions: Studies have shown racial disparities in charging decisions, with Black and Hispanic individuals more likely to be charged with more serious offenses and face harsher penalties compared to White individuals for similar offenses. 3. Pretrial Detention and Bail: Pretrial detention: Black and Hispanic individuals are more likely to be detained pretrial and less likely to be released on bail compared to White individuals, leading to longer periods of incarceration before trial and increased pressure to plead guilty to avoid prolonged detention. Bail disparities: Racial and socioeconomic disparities in access to bail contribute to inequalities in pretrial detention, with minority and low-income individuals disproportionately affected. 4. Sentencing and Incarceration: Sentencing disparities: Black and Hispanic individuals are more likely to receive longer sentences compared to White individuals for similar offenses, contributing to racial disparities in incarceration rates. Mass incarceration: The United States has the highest incarceration rate in the world, and racial minorities, particularly Black individuals, are disproportionately represented in the prison population. 5. Reentry and Recidivism: Reentry challenges: Upon release from incarceration, racial minorities face numerous barriers to successful reintegration into society, including limited access to employment, housing, education, and social support networks. Recidivism rates: Due to systemic inequalities and limited opportunities post-release, racial minorities are more likely to cycle in and out of the criminal justice system, perpetuating the cycle of incarceration and disadvantage. o. Between the world and me ▪Discussion questions ▪Thesis ▪TaNahesi Coates "Between the World and Me" by Ta-Nehisi Coates is a powerful exploration of race, identity, and the Black experience in America. Here are some discussion questions, the thesis of the book, and an overview of Ta-Nehisi Coates: Discussion Questions: How does Coates use personal narrative and historical analysis to convey his message about the experience of being Black in America? What role does fear play in shaping Coates' understanding of race and identity? How does he navigate and confront fear throughout the book? How does Coates critique the concept of the American Dream and the idea of progress in the context of racial inequality and injustice? What does Coates mean by "the Dream" and "the Dreamers," and how do these concepts shape his understanding of American society and its treatment of Black bodies? How does Coates grapple with the notion of hope in the face of systemic racism and violence against Black individuals and communities? How does Coates explore the relationship between the body, identity, and vulnerability in the context of racialized violence and oppression? Thesis: The central thesis of "Between the World and Me" revolves around Coates' exploration of the Black experience in America, particularly how systemic racism, violence, and structural inequality shape and define the lives of Black individuals. Coates argues that America's history of slavery, segregation, and ongoing racial injustice fundamentally contradicts the ideals of liberty and equality upon which the nation was founded. He presents a searing critique of the myth of the American Dream and calls attention to the pervasive fear and violence faced by Black bodies in American society. Ultimately, Coates urges readers to confront the harsh realities of race in America and to reckon with the legacy of white supremacy to work towards a more just and equitable society. Ta-Nehisi Coates: Ta-Nehisi Coates is an acclaimed writer, journalist, and educator known for his insightful commentary on race, politics, and culture in America. He has written for publications such as The Atlantic, where he gained widespread recognition for his essays on race, history, and social justice. Coates is also the author of several books, including "Between the World and Me," which won the National Book Award for Nonfiction in 2015, and "The Water Dancer," a novel exploring the legacy of slavery and the Underground Railroad. Coates' writing is characterized by its lyrical prose, meticulous research, and unflinching examination of the complexities of race and identity in America. He continues to be a prominent voice in conversations about race, history, and social justice, challenging readers to confront uncomfortable truths and envision a more equitable future. •Sexual Inequality- US beliefs about gay marriage In the United States, beliefs about gay marriage have evolved significantly over time, reflecting broader changes in societal attitudes towards LGBTQ+ rights and equality. However, sexual inequality persists in various forms, including discrimination, stigma, and legal barriers faced by LGBTQ+ individuals, particularly in relation to marriage and family rights. Historical Context: Until relatively recently, same-sex marriage was widely stigmatized and prohibited by law in the United States. For much of the country's history, marriage was legally defined as a union between a man and a woman, excluding LGBTQ+ couples from the institution of marriage and its associated legal rights and benefits. Shift in Public Opinion: Over the past few decades, there has been a notable shift in public opinion regarding gay marriage. Increased visibility and advocacy efforts by LGBTQ+ individuals and allies have contributed to greater acceptance and support for marriage equality. Polls have consistently shown a growing majority of Americans in favor of legalizing same-sex marriage. Legalization and Recognition: In a landmark decision in 2015, the U.S. Supreme Court ruled in Obergefell v. Hodges that same-sex couples have the fundamental right to marry under the Fourteenth Amendment of the U.S. Constitution. This ruling legalized gay marriage nationwide, granting LGBTQ+ couples access to the same legal rights and benefits afforded to heterosexual couples. Persistent Challenges: Despite the legalization of same-sex marriage, sexual inequality persists in various forms. LGBTQ+ individuals continue to face discrimination, prejudice, and social stigma, which can impact their ability to freely express their identities and form relationships. Furthermore, legal protections for LGBTQ+ rights vary from state to state, and some states have enacted laws or policies that undermine marriage equality or allow for discrimination based on sexual orientation or gender identity. Intersectional Issues: Sexual inequality intersects with other forms of inequality, including race, gender identity, and socioeconomic status. LGBTQ+ individuals who belong to marginalized communities may face compounded discrimination and barriers to accessing marriage rights and other resources. Advocacy and Resistance: Advocacy efforts by LGBTQ+ activists and allies continue to challenge sexual inequality and push for greater recognition of LGBTQ+ rights, including marriage equality. However, resistance to LGBTQ+ rights persists in some quarters, leading to ongoing debates and legal battles over issues such as religious exemptions, adoption rights, and transgender rights. o. Income of LGBT people The income of LGBTQ+ people can vary widely depending on factors such as education, occupation, location, and other demographic characteristics. However, research indicates that LGBTQ+ individuals as a group may face economic disparities compared to their non-LGBTQ+ counterparts. Here are some key points regarding the income of LGBTQ+ people: Wage Gap: Studies have found evidence of a wage gap between LGBTQ+ individuals and their heterosexual counterparts. This wage gap can be attributed to various factors, including workplace discrimination, bias, and unequal opportunities for career advancement. Employment Discrimination: LGBTQ+ individuals may experience discrimination in the workplace, which can impact their ability to secure employment, earn promotions, or receive equal pay for equal work. Discriminatory practices based on sexual orientation or gender identity contribute to economic inequalities within the LGBTQ+ community. Intersectionality: The economic experiences of LGBTQ+ individuals are shaped by intersecting factors such as race, gender identity, and socioeconomic status. LGBTQ+ people who belong to marginalized groups may face compounded discrimination and economic hardship, further exacerbating income disparities. Access to Benefits: Prior to the legalization of same-sex marriage in the United States, many LGBTQ+ couples were denied access to spousal benefits such as health insurance, retirement benefits, and tax advantages. Even after marriage equality, disparities in access to benefits may persist for LGBTQ+ individuals who live in states without explicit protections for LGBTQ+ rights. Housing and Homelessness: LGBTQ+ youth are disproportionately represented among homeless populations, often as a result of family rejection or discrimination. Homelessness can have significant economic consequences, including limited access to stable employment and financial resources. Policy and Advocacy Efforts: Advocacy organizations and policymakers have called attention to economic disparities within the LGBTQ+ community and advocated for policies to address these inequalities. Efforts to combat workplace discrimination, expand access to benefits, and promote economic inclusion for LGBTQ+ individuals are ongoing. o. How many people are LGBTQ ▪Changing rates •Especially for Gen Z Population Estimates: Various surveys and studies have attempted to estimate the size of the LGBTQ+ population. These estimates typically range from a few percentage points to around 10% of the population, depending on the methodology and definitions used. Changing Rates: There is evidence to suggest that the proportion of people identifying as LGBTQ+ has been increasing over time, particularly among younger generations. This trend may be influenced by factors such as greater societal acceptance, increased visibility of LGBTQ+ individuals in media and popular culture, and evolving attitudes toward sexual orientation and gender identity. Generational Differences: Generation Z, consisting of individuals born roughly between the mid-1990s and early 2010s, is often characterized by greater openness and acceptance of LGBTQ+ identities compared to older generations. Surveys and studies have shown that Generation Z is more likely to identify as LGBTQ+ or express support for LGBTQ+ rights compared to previous generations. Social Factors: Changes in societal attitudes, legal protections, and cultural norms have contributed to greater acceptance and visibility of LGBTQ+ identities. As a result, more people may feel comfortable openly identifying as LGBTQ+ or exploring their sexual orientation and gender identity. Intersectionality: It's important to recognize that LGBTQ+ identities intersect with other aspects of identity, such as race, ethnicity, socioeconomic status, and disability. Rates of LGBTQ+ identification and experiences of discrimination may vary within and across different demographic groups. o. Heterosexism o. Homophobia, hate crimes, and discrim Heterosexism refers to the belief in and promotion of heterosexuality as the norm or superior sexual orientation, while marginalizing or discriminating against other sexual orientations. This ideology can manifest in various ways, including homophobia, hate crimes, and discrimination. Here's a breakdown: Homophobia: This is an irrational fear, hatred, or discomfort toward individuals who are perceived as being gay, lesbian, bisexual, or transgender. Homophobia can lead to prejudice, discrimination, and violence against LGBTQ+ individuals. It may be fueled by ignorance, cultural norms, religious beliefs, or personal biases. Hate Crimes: Hate crimes are criminal acts motivated by bias or prejudice against a particular group, including LGBTQ+ individuals. These crimes can range from verbal harassment and physical assault to vandalism, sexual assault, or even murder. Hate crimes targeting LGBTQ+ individuals often stem from homophobia and transphobia and can have devastating effects on individuals and communities. Discrimination: LGBTQ+ individuals may face discrimination in various areas of life, including employment, housing, education, healthcare, and public accommodations. Heterosexism can manifest in policies, practices, and social attitudes that favor heterosexual individuals while disadvantaging or excluding LGBTQ+ individuals. Discrimination based on sexual orientation or gender identity is often illegal in many jurisdictions, but it still persists in many forms. •Sex- Frequency and patterns o. Difference in reporting o. Contemporary rates and patterns for Gen Z and Millennials o. Changes in dating and partnering Discussions around sex, its frequency, patterns, and changes in contemporary rates and patterns among different generations, particularly Gen Z (born roughly between the mid-to-late 1990s and early 2010s) and Millennials (born roughly between the early 1980s and mid-to-late 1990s), often involve several key points: Difference in Reporting: There's often a difference in how different generations report their sexual behaviors. For example, older generations may be more conservative or private about discussing their sexual activities, while younger generations, such as Gen Z, may be more open and transparent about their experiences, thanks in part to the normalization of discussions around sex in popular culture, social media, and the internet. Contemporary Rates and Patterns: Studies have shown that there are shifts in sexual behaviors and attitudes among younger generations compared to older ones. For instance, surveys suggest that Gen Z and Millennials may be having sex less frequently than previous generations did at the same age. Factors contributing to this trend may include increased access to technology, changing social norms around relationships and sexuality, and concerns about sexual health and consent. Changes in Dating and Partnering: With the rise of dating apps and online platforms, there have been significant changes in how people meet and form relationships. Gen Z and Millennials are more likely to meet potential partners online than through traditional means like mutual friends or social events. This shift has also led to changes in dating dynamics, with some research suggesting that younger generations are more likely to engage in casual relationships or hookups rather than long-term commitments. ▪Changes in sexual frequency Changes in sexual frequency refer to shifts or variations in how often individuals engage in sexual activity over time. Several factors can influence changes in sexual frequency, including societal norms, cultural attitudes toward sex, individual preferences, relationship dynamics, health considerations, and external stressors. Here are some key points regarding changes in sexual frequency: Generational Shifts: Research suggests that there have been generational differences in sexual frequency. For example, some studies indicate that younger generations, such as Millennials and Gen Z, may be having sex less frequently than previous generations did at the same age. This trend could be attributed to various factors, including increased use of technology, changes in dating practices, and shifting societal attitudes toward sex. Relationship Status: Changes in relationship status can impact sexual frequency. For example, individuals in long-term relationships or marriages may experience fluctuations in sexual activity over time due to factors such as work stress, family responsibilities, or changes in emotional intimacy. Conversely, individuals who are single or casually dating may have more variability in their sexual frequency depending on their social and dating experiences. Health Factors: Physical and mental health can influence sexual frequency. Health conditions, medications, hormonal changes, and psychological factors such as stress, anxiety, or depression can affect libido and sexual desire, leading to changes in sexual activity levels. Additionally, experiences such as pregnancy, childbirth, and menopause can also impact sexual frequency for individuals and couples. Social and Cultural Factors: Societal norms, cultural attitudes, and media representations of sex can influence individuals' perceptions and behaviors regarding sexual activity. Changes in social norms around sexuality, gender roles, and relationship dynamics may contribute to shifts in sexual frequency among different demographic groups. Technological Influence: The widespread availability of digital media and online platforms has reshaped how people connect and interact, including in the realm of sexuality. The rise of social media, dating apps, and online pornography may impact sexual behaviors and attitudes, potentially affecting sexual frequency among different populations. Vocabulary •Biological Notions Of Race Biological notions of race refer to perspectives that view race as a biological or genetic category, often emphasizing physical differences among human populations. These perspectives typically posit that there are distinct and significant biological differences between racial groups, such as variations in genetic makeup, physiology, or disease susceptibility. •Social Construct A social construct refers to a concept or idea that is created and defined by society, rather than being inherent to the natural world. These constructs are shaped by social, cultural, historical, and political factors, and they vary across different societies and contexts. Social constructs are often accepted as reality by members of a society, influencing beliefs, attitudes, behaviors, and social interactions. •Social Construction Of Race The social construction of race refers to the process by which societal beliefs, categories, and meanings about race are created, shaped, and perpetuated within a particular cultural and historical context. Unlike biological notions of race, which posit that race is a fixed and objective category based on physical or genetic differences, the social constructionist perspective emphasizes that race is a product of social, cultural, and political forces rather than biological reality. •Racial Formation Theory Racial Formation Theory, developed by sociologists Michael Omi and Howard Winant in the late 20th century, is a conceptual framework that seeks to understand how race and racial categories are socially constructed and transformed over time. The theory emphasizes the dynamic and contingent nature of race, highlighting how racial identities, meanings, and hierarchies are produced, contested, and reconfigured within specific historical and social contexts. •Ethnicity Ethnicity refers to the cultural, social, and sometimes biological characteristics that distinguish one group of people from another. It is a complex and multifaceted concept that encompasses shared ancestry, language, religion, customs, traditions, and other cultural practices. Unlike race, which is often understood in terms of physical or biological traits, ethnicity is primarily based on cultural affiliation and identification. •Globalization Globalization refers to the increasing interconnectedness and interdependence of societies and economies around the world. It involves the exchange of goods, services, information, technology, culture, and ideas on a global scale, leading to the integration of economies and societies into a single global system. Key aspects of globalization include: •Immigration o. Legal (Voluntary) o. Illegal (Voluntary) o. Forced Immigration refers to the act of individuals or groups moving from one country to another to reside there permanently or temporarily. Immigration can occur for various reasons, including economic opportunities, family reunification, seeking asylum or refuge, or fleeing persecution, conflict, or environmental disasters. There are three broad categories of immigration: Legal Immigration (Voluntary): Legal immigration occurs when individuals enter a country with the proper authorization and documentation, such as visas, work permits, or residency permits. This type of immigration is voluntary and typically follows established immigration laws and regulations of the destination country. Legal immigrants often come to pursue education, and work opportunities, join family members, or seek refuge through legal channels. Illegal Immigration (Voluntary): Illegal immigration, also known as undocumented or irregular migration, refers to the movement of individuals across national borders without proper authorization or documentation under the destination country's immigration laws. This type of immigration is voluntary but violates the immigration laws of the destination country. Reasons for illegal immigration may include economic factors, lack of legal pathways for migration, family reunification, or fleeing violence or persecution. Illegal immigrants often face risks such as exploitation, deportation, detention, and limited access to essential services. Forced Immigration: Forced immigration occurs when individuals are compelled to leave their home countries against their will due to persecution, conflict, environmental disasters, or other circumstances that threaten their safety, security, or well-being. This type of immigration is involuntary and may involve refugees, asylum seekers, internally displaced persons (IDPs), or victims of human trafficking. Forced immigrants often seek protection and assistance from international organizations, such as the United Nations High Commissioner for Refugees (UNHCR), and may eventually be resettled in a third country or return home when conditions improve. •Emigration Emigration refers to the act of individuals or groups leaving their country of origin to settle in another country. It involves the permanent or long-term relocation of people from their home country to a new destination. Emigration is the opposite of immigration, which involves individuals or groups entering a new country to reside there. •Refugee (as defined by the US) In the United States, a refugee is defined as a person who is outside their country of nationality or habitual residence due to a well-founded fear of persecution on account of race, religion, nationality, membership in a particular social group, or political opinion, and who is unable or unwilling to return to that country. Refugees are granted legal protection and assistance under international law, including the 1951 Convention Relating to the Status of Refugees and its 1967 Protocol, to which the United States is a signatory. To be recognized as a refugee in the United States, individuals must undergo a thorough screening process conducted by the U.S. Citizenship and Immigration Services (USCIS) or the United Nations High Commissioner for Refugees (UNHCR), depending on the circumstances. This process involves interviews, background checks, and verification of the individual's refugee status. Once granted refugee status, individuals may be eligible for resettlement in the United States, where they receive assistance with housing, employment, education, and other services to help them rebuild their lives. Refugees differ from other categories of migrants, such as immigrants and asylum seekers, in that they have been forced to flee their home countries due to persecution or violence and are unable to return safely. As such, they are afforded specific legal protections and rights under international and domestic law. •Remittance Remittance refers to the transfer of money or other assets by a person living and working in one country to their family or others residing in their country of origin. It is a vital source of financial support for many families in developing countries, where remittances often constitute a significant portion of the national income. Remittances can be sent through various channels, including banks, money transfer operators (MTOs), online platforms, and informal channels such as friends or relatives carrying cash. The funds sent as remittances are typically used by recipients to cover essential expenses such as food, housing, education, healthcare, and investments in small businesses or agriculture. Remittances play a crucial role in poverty reduction and economic development in recipient countries, providing a lifeline for millions of households and contributing to local economies through increased consumption and investment. Additionally, remittances can help reduce inequality by redistributing wealth from higher-income countries to lower-income countries. For many migrants, sending remittances is a way to fulfill their financial obligations to their families and communities back home and to support their loved ones' well-being and aspirations. Governments and international organizations often support policies and initiatives aimed at facilitating remittance flows, reducing transfer costs, and promoting financial inclusion among migrant populations. •Model Minority The term "model minority" refers to a demographic group, typically an ethnic or racial minority, that is perceived as achieving a higher degree of socioeconomic success than the population average. This term is often applied to Asian Americans in the United States, but it can also be used to describe other groups in various countries. Characteristics commonly associated with the model minority stereotype include high levels of educational attainment, strong work ethic, stable family structures, and economic success. The model minority stereotype suggests that members of these groups have overcome discrimination and adversity through hard work, perseverance, and adherence to cultural values such as emphasis on education and strong family ties. •Assimilation o. Downward Assimilation Assimilation is a process through which individuals or groups adopt the cultural norms, values, and behaviors of the dominant society. It involves the integration of minority or immigrant groups into the mainstream culture of a society. Assimilation can occur voluntarily as individuals or groups seek to adapt to their new environment, or it can be enforced through social, economic, or political pressures. Downward assimilation refers to a situation in which individuals or groups adopt the norms and values of a lower socioeconomic status group rather than those of the dominant society. This can occur when individuals or groups face barriers to upward mobility or experience discrimination and marginalization within the dominant culture. Downward assimilation may involve adopting behaviors, attitudes, or lifestyles associated with poverty or social disadvantage. Downward assimilation can be a response to socioeconomic inequality, limited opportunities for social mobility, or experiences of discrimination and marginalization. It may also reflect a sense of alienation or disconnection from the dominant culture, leading individuals or groups to identify more closely with subcultures or communities that share similar experiences or values. While assimilation is often seen as a way for immigrants or minority groups to achieve social and economic success in their new society, downward assimilation highlights the complexities and challenges that individuals or groups may face in the process of integration. It underscores the importance of addressing structural inequalities and promoting social inclusion to ensure that all members of society have equal opportunities to thrive. •Paradigm o. Paradigm Shift A paradigm is a set of beliefs, assumptions, and practices that define how a particular discipline or field of study approaches problems and generates knowledge. It serves as a framework for understanding and interpreting phenomena within that discipline. A paradigm shift refers to a fundamental change in the basic assumptions, concepts, and practices of a scientific or intellectual framework. It occurs when new discoveries, theories, or perspectives challenge the existing paradigm and lead to a reevaluation of fundamental concepts and methods. •Gender Gender refers to the social, cultural, and behavioral characteristics, roles, and expectations that societies attribute to individuals based on their perceived sex. While sex typically refers to biological differences, such as chromosomes, hormones, and reproductive anatomy, gender encompasses a broader range of characteristics and identities. •Gender Expression Gender expression refers to the outward manifestation of an individual's gender identity, typically through behavior, clothing, hairstyle, voice, or other aspects of appearance and presentation. It encompasses the ways in which individuals express their gender to others and may include both intentional and unintentional cues that communicate aspects of their gender identity. •Gender Identity Gender identity refers to a person's deeply-felt internal sense of their own gender, which may be male, female, a blend of both, or neither. It is an intrinsic aspect of individual identity and may or may not correspond with the sex assigned to them at birth. Gender identity is distinct from biological sex, which is typically assigned based on physical characteristics such as anatomy and chromosomes. •Sexual Identity Sexual identity refers to an individual's enduring pattern of romantic or sexual attraction, as well as their sense of self in relation to that attraction. It encompasses the internal understanding of one's sexual orientation and may include categories such as heterosexual, homosexual, bisexual, pansexual, asexual, and more. •Sexuality Sexuality refers to the complex interplay of biological, psychological, social, cultural, and emotional factors that shape an individual's experience of their sexual desires, attractions, behaviors, and relationships. It encompasses a wide range of dimensions, including but not limited to: •Sex Sex, in the context of human behavior and relationships, refers to a broad range of physical, emotional, and social aspects related to sexual activity, attraction, and expression. •Self-policing Self-policing refers to the practice of individuals or groups regulating their own behavior, actions, or attitudes according to internal standards, values, or norms, rather than relying solely on external laws, rules, or authorities for guidance or enforcement. It involves taking personal responsibility for one's actions and adhering to ethical principles or social expectations without the need for external coercion or supervision. •Gender Queer Genderqueer is a term used to describe individuals whose gender identity does not conform to traditional binary notions of male and female. Genderqueer people may identify as a blend of both genders, as neither exclusively male nor female, or as a different gender entirely. They may reject the idea of fixed gender categories altogether and view gender as fluid and non-binary. •Gender Binary The gender binary refers to the classification of gender into two distinct and opposite categories: male and female. It's a cultural, societal, and often institutional framework that assumes there are only two genders, each associated with specific roles, behaviors, attributes, and expectations. This binary understanding of gender typically aligns with biological sex assigned at birth, where individuals are categorized as either male or female based on physical characteristics such as genitalia and chromosomes. •Man Box o. Tony Porter The "Man Box" is a concept popularized by Tony Porter, an activist and educator known for his work in promoting healthy, respectful, and equitable notions of masculinity. The term refers to a set of societal expectations, norms, and stereotypes that prescribe how men should behave, think, and feel. These expectations are often rigid and restrictive, dictating that men should conform to certain ideals of masculinity while suppressing traits or behaviors that are perceived as feminine or weak. •Hierarchy Hierarchy refers to a system or structure in which people or groups are ranked according to their status, authority, or importance relative to one another. It often involves a vertical arrangement, with individuals or entities positioned at different levels based on criteria such as power, wealth, social class, or organizational position. •Ascribed Identity An ascribed identity is a social identity that is assigned to an individual based on characteristics such as age, race, ethnicity, gender, and socioeconomic status, over which the individual may have little or no control. These identities are typically attributed to individuals at birth or early in life and are often based on external factors such as physical appearance, family background, or cultural heritage. •Achieved Identity An achieved identity is a social identity that an individual acquires through their own actions, efforts, choices, and accomplishments. Unlike ascribed identities, which are assigned to individuals based on factors such as race, gender, or socioeconomic status, achieved identities are developed over time through personal agency and interaction with one's environment. •Queer Theory o. A conflict theory where the conflict is the level of patriarchy o. Judith Butler Queer theory is a theoretical framework within gender studies and sociology that challenges traditional understandings of gender and sexuality. Developed primarily in the late 20th century, queer theory emerged as a response to the limitations of earlier feminist and gay/lesbian theories, which tended to essentialize gender and sexual identities. At its core, queer theory seeks to deconstruct binary categories such as male/female and gay/straight, as well as the norms and power structures associated with them. It questions the idea of fixed, natural, or essential identities, arguing instead that identities are fluid, socially constructed, and context-dependent. •Homophobia Homophobia refers to a range of negative attitudes, feelings, and behaviors directed towards individuals who are perceived to be gay, lesbian, bisexual, or transgender (LGBT), as well as towards same-sex relationships or behaviors. It encompasses prejudice, discrimination, and hostility based on a person's sexual orientation or gender identity. •Heterosexism Heterosexism refers to the belief in and privileging of heterosexuality as the normative and superior sexual orientation, while marginalizing and stigmatizing non-heterosexual identities. It operates on the assumption that heterosexuality is the only natural or acceptable form of sexual orientation, leading to discrimination, prejudice, and the exclusion of LGBTQ+ (lesbian, gay, bisexual, transgender, queer, and other non-heterosexual or non-cisgender) individuals. •Culture Culture encompasses the shared beliefs, values, norms, customs, traditions, language, symbols, and practices that are learned and transmitted within a particular social group or community. It shapes individuals' identities, behaviors, and worldviews, influencing how people perceive themselves and others, interact with one another, and interpret the world around them. •FCC The Federal Communications Commission (FCC) is an independent agency of the United States government that regulates interstate and international communications by radio, television, wire, satellite, and cable. It was established by the Communications Act of 1934 and is charged with overseeing various aspects of telecommunications and broadcasting to ensure the public interest is served. •Fairness Doctrine o. Repeal of and effects of repeal The Fairness Doctrine was a policy introduced by the Federal Communications Commission (FCC) in 1949 to ensure that broadcasters presented balanced and fair coverage of controversial issues. It required broadcasters to devote airtime to discussing contrasting views on matters of public importance and to provide an opportunity for opposing viewpoints to be heard. Key points about the Fairness Doctrine include: Intent: The Fairness Doctrine aimed to promote the public interest by ensuring that the public had access to a diverse range of viewpoints on important issues. It was based on the principle that broadcasters, who held licenses to use the public airwaves, had an obligation to serve the public interest. Requirements: Under the Fairness Doctrine, broadcasters were required to cover controversial issues of public importance and to provide reasonable opportunities for contrasting viewpoints to be presented. This often meant offering airtime to individuals or groups with differing perspectives on the issue being discussed. Implementation: The Fairness Doctrine was enforced through FCC regulations, and broadcasters found to be in violation of the doctrine could face penalties, including the potential loss of their broadcast licenses. Repeal: The Fairness Doctrine came under increasing criticism in the 1980s from both conservative and liberal groups, who argued that it infringed on broadcasters' First Amendment rights and stifled free speech. In 1987, the FCC under Chairman Dennis R. Patrick abolished the Fairness Doctrine, citing changes in the media landscape, including the rise of cable television and the growth of alternative sources of information. Effects of Repeal: The repeal of the Fairness Doctrine led to significant changes in the media environment, particularly in talk radio and television news. Without the requirement to provide balanced coverage of controversial issues, broadcasters had more freedom to air programming reflecting a particular ideological viewpoint, leading to the rise of opinion-driven, partisan media outlets. Some critics argue that the repeal contributed to increased polarization and the spread of misinformation in the media landscape. •Propaganda Propaganda refers to information, ideas, or messages spread with the intention of influencing people's opinions, beliefs, or actions in a particular direction, often to promote a specific agenda or ideology. It can take various forms, including written or spoken communication, images, videos, and other media formats. •Media conglomeration (Also called Media Consolidation) Media conglomeration, also known as media consolidation, refers to the process by which ownership and control of media companies become concentrated in the hands of a few large corporations or conglomerates. This trend has been increasingly prominent in the media industry, particularly in recent decades, driven by factors such as deregulation, technological advancements, and the pursuit of economies of scale. •Vertical integration Vertical integration is a business strategy in which a company extends its operations along the supply chain by acquiring or merging with companies that are involved in different stages of the production process. Rather than just focusing on one aspect of production, such as manufacturing or distribution, a vertically integrated company controls multiple stages of the supply chain, from raw materials to the final product or service delivered to the customer. •Horizontal integration Horizontal integration is a business strategy in which a company expands its presence in the same stage of the production process or industry value chain by acquiring or merging with competitors or companies operating in the same industry. Unlike vertical integration, which involves expanding into different stages of the production process (such as upstream suppliers or downstream distribution channels), horizontal integration focuses on consolidating firms that operate at the same level of the value chain. •Monopoly A monopoly is a market structure characterized by a single seller dominating the entire market for a particular product or service. In a monopoly, the single seller faces no competition, giving it significant control over the price and quantity of goods or services sold. Monopolies can arise due to various factors, including barriers to entry, economies of scale, control over essential resources, or government regulations. •Mass Media Mass media refers to various forms of communication that reach large audiences simultaneously. These channels include newspapers, magazines, radio, television, and the internet. Mass media play a crucial role in shaping public opinion, disseminating information, influencing social norms, and facilitating cultural exchange on a global scale. •Mainstream Media Mainstream media refers to large-scale, widely recognized media outlets that reach a broad audience and typically adhere to established journalistic practices and professional standards. These media organizations include newspapers, television networks, radio stations, magazines, and online news websites that are well-known and widely consumed by the general public. •Independent Media Independent media refers to media outlets that operate free from corporate or government influence and are often characterized by their commitment to journalistic integrity, editorial independence, and diverse perspectives. Unlike mainstream media, which may be owned by large corporations or conglomerates and subject to commercial pressures, independent media organizations prioritize principles such as transparency, accountability, and serving the public interest. •Social Media Social media refers to online platforms and services that allow users to create, share, and interact with content and other users in virtual communities. These platforms enable individuals and groups to connect, communicate, collaborate, and engage with each other in various forms of digital interaction. Social media has become an integral part of modern communication, influencing how people connect, consume information, and participate in social, cultural, and political activities. •Media Literacy Media literacy refers to the ability to access, analyze, evaluate, and critically interpret various forms of media content, including print, broadcast, digital, and social media. It involves understanding how media messages are created, disseminated, and consumed, as well as recognizing the influence of media on individuals, society, and culture. Media literacy empowers individuals to become informed, discerning, and responsible media consumers and creators by developing essential skills and competencies related to media literacy include: •Digital Divide The digital divide refers to the gap between those who have access to digital technologies, such as computers, smartphones, and the internet, and those who do not. This gap can exist within and between countries, regions, communities, socioeconomic groups, and demographic populations. The digital divide encompasses disparities in access to digital infrastructure, connectivity, devices, skills, and digital literacy, which can hinder individuals' ability to participate fully in the digital age and benefit from the opportunities offered by digital technologies. •Internet Addiction Internet addiction, also known as problematic internet use or internet gaming disorder, refers to excessive, compulsive, and uncontrollable use of the internet, leading to negative consequences in various areas of an individual's life, including personal, social, academic, and occupational functioning. It is characterized by a preoccupation with internet activities, loss of control over internet use, withdrawal symptoms when internet access is restricted, and continued use despite experiencing adverse effects. •Demography Demography is the scientific study of human populations, including their size, structure, distribution, composition, and dynamics over time. It encompasses a wide range of topics related to population dynamics, such as birth rates, death rates, migration patterns, fertility rates, age distribution, and demographic trends. •Overpopulation Overpopulation refers to a situation where the number of people in a given area exceeds the carrying capacity of the environment, leading to various negative consequences. It is typically characterized by an imbalance between the human population and the available resources and infrastructure needed to support it sustainably. •Flattening "Flattening" can refer to several concepts depending on the context: Flattening the Curve: In the context of public health, "flattening the curve" refers to efforts to slow the spread of a contagious disease, such as COVID-19, in order to reduce the peak number of cases and prevent overwhelming healthcare systems. This is typically achieved through measures such as social distancing, mask-wearing, hand hygiene, quarantine, and vaccination. Flattening the Organization: In business or management contexts, "flattening the organization" refers to reducing hierarchical layers or levels within a company or institution. This can involve decentralizing decision-making, empowering employees, streamlining communication channels, and eliminating unnecessary bureaucracy in order to increase efficiency, responsiveness, and innovation. Flattening the Earth: In the context of globalization and technology, "flattening the earth" is a concept popularized by Thomas Friedman in his book "The World is Flat." It refers to the leveling effect of globalization and digital technology, which has enabled greater connectivity, communication, and competition on a global scale. This has led to increased interconnectedness, economic integration, and cultural exchange among people and nations •Urbanization o. Overurbanization Urbanization refers to the process by which an increasing proportion of a population migrates from rural to urban areas, resulting in the growth of cities and towns. This phenomenon is typically driven by factors such as industrialization, economic development, job opportunities, better infrastructure, and improved living standards in urban areas. Overurbanization, on the other hand, refers to a situation where urban growth outpaces the capacity of infrastructure, resources, and services to support it. This can lead to various challenges and problems, including overcrowding, inadequate housing, traffic congestion, pollution, strained public services, and social inequalities. Overurbanization often occurs in developing countries where urbanization is rapid and unplanned, resulting in slums, informal settlements, and other urban problems. Efforts to address overurbanization typically involve urban planning, infrastructure development, social programs, and policies to promote sustainable urban growth and improve living conditions for urban residents. •Gentrification Gentrification is a process of urban development whereby previously neglected or economically disadvantaged neighborhoods undergo revitalization, typically resulting in an influx of wealthier residents and businesses. This transformation often leads to increased property values, improved infrastructure, and cultural changes in the area. •Separation of Spheres o. Peak of rigidly defined gender roles in American and other developed countries The peak of rigidly defined gender roles in American and other developed countries is typically associated with the mid-20th century, particularly in the post-World War II era up until the 1960s. During this time, there was a strong societal emphasis on traditional gender norms, with distinct expectations and roles for men and women. ▪1950’s The 1950s in the United States is often characterized as a period of post-World War II prosperity and cultural conservatism. Here are some key aspects of the 1950s: Economic Boom: The 1950s saw significant economic growth in the United States, fueled by the post-war industrial boom. This period is often referred to as the "Golden Age of Capitalism" or the "Economic Miracle." The GI Bill provided educational and housing benefits to returning veterans, contributing to a rise in homeownership and the expansion of the middle class. Suburbanization: The 1950s witnessed a mass migration of Americans from cities to suburbs. Suburbanization was driven by factors such as the availability of affordable housing, government subsidies for suburban development, and the desire for a more peaceful and family-oriented lifestyle. Levittown, New York, became a symbol of suburban expansion with its mass-produced, affordable housing developments. Baby Boom: The post-war period also saw a significant increase in birth rates, known as the "baby boom." Returning servicemen started families, leading to a surge in childbirth rates that lasted throughout the 1950s. Cultural Conservatism: The 1950s is often depicted as a time of cultural conformity and conservatism. Traditional gender roles were reinforced, with men as breadwinners and women as homemakers. The nuclear family model, consisting of a husband, wife, and children, was idealized. Cold War Era: The 1950s were marked by the height of the Cold War between the United States and the Soviet Union. The fear of communism led to anti-communist hysteria and the rise of McCarthyism, characterized by investigations into alleged communist influence in American society. Civil Rights Movement: The 1950s laid the groundwork for the civil rights movement, which sought to end racial segregation and discrimination against African Americans. Landmark events such as the Brown v. Board of Education Supreme Court decision (1954) and the Montgomery Bus Boycott (1955-1956) set the stage for the activism of the 1960s. Popular Culture: The 1950s saw the rise of television as a dominant form of entertainment, with shows like "I Love Lucy," "The Ed Sullivan Show," and "Leave It to Beaver" capturing the imagination of American audiences. Rock and roll music also emerged as a powerful cultural force, with artists like Elvis Presley revolutionizing the music industry. •I-gen "I-Gen" is a term sometimes used to refer to the generation of individuals born between the mid-to-late 1990s and the mid-2010s. This generation is also commonly known as Generation Z or Gen Z. The prefix "i" may stand for various things, including "internet," "individualistic," or "information," reflecting the generation's relationship with technology and their status as digital natives. o. Jean Twenge Jean Twenge is a psychologist and author known for her research on generational differences, particularly focusing on the characteristics and behaviors of millennials and Generation Z. She has written several books on the subject, including "Generation Me" and "iGen: Why Today's Super-Connected Kids Are Growing Up Less Rebellious, More Tolerant, Less Happy — and Completely Unprepared for Adulthood." Twenge's work often explores how cultural and societal factors, such as technology, parenting styles, and economic conditions, influence the attitudes and behaviors of different generations. She has conducted extensive research using large-scale surveys to identify trends and patterns in generational shifts, drawing attention to changes in areas such as mental health, self-esteem, and social relationships. While Twenge's research has garnered attention for highlighting some of the challenges and concerns associated with younger generations, such as increased rates of anxiety and depression, her work has also sparked debate and criticism within the field of psychology and sociology. Some scholars have questioned the generalizations made about entire generations and the potential oversimplification of complex societal phenomena. Nonetheless, Twenge's work continues to be influential in discussions about generational differences and the impact of cultural change on individuals' lives.
