EU PRIVATE LAW W1 Reading Notes “Martijn W. Hesselink: setting the scene” First definition: Private law is the law applicable to private (or horizontal) relationships Second definition: Relating only to private interests, as opposed to public interests >> sometimes inspired by a concern to keep private law ‘pure’ in this specific and controversial sense of being concerned only with private interests and preventing the infiltration of public concerns into disputes governed by private law Increasing Europeanisation (1980s) effect on private law - Most directives in the field of private law, including the entire body of EU consumer law, have had Art 114 TFEU (or its predecessors) as their legal basis - Regulations, that bring uniform EU law, are less frequent in the field of private law, but there exist some prominent instances, eg in EU financial law - Fundamental rights have had an increasingly important impact on private law relationships already governed, directly or indirectly, by EU law - The Court of Justice of the EU has played a prominent, sometimes plainly activist, role, especially with regard to consumer protection and to fundamental rights • Preliminary rulings Inequality: - Positive and normative questions • Positive: How much inequality is there? What types of inequality are there? • Normative: how much equality ought there to be, or, put differently, how much inequality is acceptable? - Equality of what? • Income - policies aiming at reducing inequality (or wealth) of income include income tax (plus capital tax and inheritance tax) and various social security measures (eg unemployment benefits, a universal basic income) • Needs - Theory 1: everyone is entitled at least to the satisfaction of their needs (basic needs). - Theory 2: people are equally entitled to just as much as each of them needs, nothing more • Opportunity - Prominent instruments for reducing inequality of opportunity are measures (including quotas) aiming to improve equal access to school, to healthcare and (other) essential services, or to high-ranking positions • Power Interpersonal (or relational) inequality and injustice occurs when, in a relationship between two or more persons, one is in a better position than the other(s) in terms, for example, of bargaining power, negotiation skills, expertise, experience, independence, cognitive biases, or luck Who should breach inequality? What of the recipients? EU citizens? Formal equality is usually considered a basic or minimum requirement of justice and rationality — Formal equality then simply means that people are treated equally already when all individuals are treated the same way, whatever their specific characteristics or situations >> however: frequently regarded as insufficient Substantive Inequality: new doctrines such as unconscionability, economic duress, abuse of circumstances or unfair exploitation, and, especially, the sets of rules aiming at the protection of certain categories of weaker or vulnerable parties, such as workers, tenants, consumers, and the rules against the discrimination on grounds of gender, ethnic background or religion Course Objective: Identifying the EU’s private law as an agent of inequality and equality in Europe Reading 2: Laura Burgers, Marija Bartl, and Chantal Mak, “Introduction: The Evolving Concept of Private Law in Europe”, Handbook: Uncovering European Private Law (2022) Public/private divide >> privatisation of public function Private autonomy as general principle of private law — Substantive side: (eg. freedom of contract) - promotion of material or substantive equality. This can be called the ‘social’ or ‘societal’ dimension of private law. >> To the extent that the promotion is taken up by the judiciary, this is often called the ‘materialisation’ of private law - Constitutionalisation of private law (second half of 20th century) Procedural side: one of the parties decides what part of their conflict they want to take to court, and whether they want to do that at all. - Party autonomy: This means that parties who enter into a contract, are free to negotiate what law applies to their contract and to which court or arbiter they will resort in case of conflict. Private Law-makers in EU - We understand private law as law made by public authorities, i.e. legislatures and judiciaries - Rules made by private parties - fall within the sphere of freedom of contract or self-regulation - ‘Civil law’ is frequently used a synonym of ‘private law’. Civil procedural law is typically laid down in codes of civil procedure. It refers to procedural rules in private legal disputes and contains rules on, for example: evidence, possibilities for appeals and enforcement of judgments. What is EU private Law? — EU law impacting private legal relations, i.e. law emanating from the EU level, or ‘EU private law’ >> For over two decades, from 1989 onwards, attempts were made to draft a civil code for the European Union. However, no consensus could be reached, which in turn exposed how legal- politically salient issues of private law are, and what importance civil codes have for national identities >> Idea that EU law threatens the coherence, essence or autonomy of national private laws Lochner Case: >> Lochner allowed an employee to work more then 60 hours in a week >> ‘violates bakeshop Act’ >> Lochner claims it should have been interpreted to contain the freedom to contract among the rights encompassed by substantive due process - Does the Bakeshop Act violate the liberty protected by the Due Process Clause of the Fourteenth Amendment? 5-4 Majoritarian decision: The New York law violated "liberty of contract" protected by the Due Process Clause of the Fourteenth Amendment - The statute interfered with the freedom of contract, and thus the Fourteenth Amendment's right to liberty afforded to employer and employee - New York law failed the rational basis test for determining whether government action is constitutional - The Bakeshop Act had no rational basis because long working hours did not dramatically undermine the health of employees, and baking is not particularly dangerous

Generalization and Discrimination 1. generalization: responding similarly to a range of similar stimuli a. Pavlov taught dog to respond to a circle; dog would respond to other figures 2. discrimination: the ability to respond differently to similar but distinct stimuli a. Pavlov proved by never pairing the food with the oval Extinction and Spontaneous Recovery 1. extinction: the gradual disappearance of a conditioned response when the conditioned stimulus is repeatedly presented without the unconditioned stimulus a. Pavlov stopped giving food after sound of tuning fork 2. spontaneous recovery: when a CR reappears when a CS occurs without a US John Watson & Rosalie Rayner: the case of Little Albert a. explored the relationship between classical conditioning and emotional responses b. trained 11-month old Albert to fear lab rat c.

B.F. Skinner: trained rats to respond to lights and sounds (Skinner Box) 2. reinforcement: stimulus or event that follows a response and increases the likelihood that the response will be repeated positive reinforcement: adding something desirable after a behavior occurs 1. food (Skinner Box), social approval, money, extra privileges b. negative reinforcement: removal of something undesirable after a behavior occurs 1. changing a smoke alarm battery, buckling seatbelt, use of an umbrella Primary and Secondary Reinforcers 1. primary reinforcer: stimulus that is naturally rewarding, such as food or water 2. secondary reinforcer: stimulus such as money that becomes rewarding through its link with a primary reinforcer a. Wolfe experiment 1936 (Chimpanzees) b. money is best example Schedules of Reinforcement 1. continuous schedule: reinforcing behavior every time it occurs 2. partial schedule: positive reinforcement occurs sporadically a. acquired behaviors are more slowly established but are more persistent 1. discovered when the Skinner Box kept breaking down ratio schedules: reinforcement based on the number of responses 1. fixed-ratio: reinforcement depends on specified quantity of responses a. most consumer loyalty punch cards 2. variable-ratio: reinforcement after varying number of responses a. slot machines, door to door sales, telemarketing 1. very resistant to extinction interval schedules: reinforcement occurs after an amount of time elapses 1. fixed-interval: reinforcement of first response after a fixed amount of time has passed a. salaries, cramming for tests 2. variable-interval: reinforcement of the first response after varying amounts of time a. fishing, pop quizzes 1. very resistant to extinction shaping: technique in which the desired behavior is “molded” by first rewarding any act similar to that behavior and then requiring ever-closer approximations to the desired behavior before giving the reward 1. flag-raising rat a. reinforce rat for approaching flagpole b. reinforce after rat raises paw while near flagpole c. reinforce after rat gets on hind legs while near flagpole d. reinforce after rat nibbles at cord while on hind legs Combining Responses: Chaining 1. response chains: learned reactions that follow one another in sequence, each reaction producing the signal for the next a. complex skill of swimming involves organizing large response chains 1. arm stroke chain, breathing chain, leg kick chain Aversive Control: process of influencing behavior by means of unpleasant stimuli completed through use of negative reinforcers or punishers A. Negative Reinforcement: increasing the strength of a given response by removing or preventing a painful stimulus when the response occurs 1. escape conditioning: training of an organism to remove or terminate an unpleasant stimulus a. parents removing an unpleasant meal when child whines and gags while eating avoidance conditioning: training of an organism to respond so as to prevent the occurrence of an unpleasant stimulus a. parents deciding against presenting an unpleasant circumstance because child whines at the possibility Punishment 1. leads to the removal or reduction of behavior 2. must be unpleasant to work a. some reprimands may actually serve as reinforcers 3. positive punishment: adding unpleasant circumstances 4. negative punishment: removal of pleasant circumstances Disadvantages of Punishment 1. can produce rage, aggression, and fear in children 2. spanking can lead to increased aggression toward other children 3. can lead to children avoiding person who punishes 4. fails to teach appropriate and acceptable behavior Cognitive Learning 1. social learning: process of altering behavior by observing and imitating the behavior of others a. learning goes beyond mechanical responses to stimuli or reinforcement 2. cognitive learning: form of altering behavior that involves mental processes and may result from observation or imitation Latent Learning and Cognitive Maps 1. Wolfgang Kohler: chimpanzee study on insight 2. Edward Tolman: rat study on cognitive maps and latent learning a. cognitive map: a mental picture of spatial relationships or relationships between events b. latent learning: alteration of a behavioral tendency that is not demonstrated by an immediate, observable change in behavior Learned Helplessness: condition in which repeated attempts to control a situation fail, resulting in the belief that the situation is uncontrollable 1. college students/noise study 2. Martin Seligman Theory a. stop trying b. lower self-esteem c. depression ensues Modeling: learning by imitating others; copying behavior mimicry: performing old, established responses that we might not be using at the time. 2. observational learning: learning to perform a behavior after watching others perform it a. Albert Bandura: Bobo doll experiment 3. disinhibition: the increased likelihood a behavior will be repeated when observed behavior is not punished a. often used to alleviate phobias the systematic application of learning principles to change people’s actions or feelings A. Computer-Assisted Instruction 1. S.L. Pressey (1933) & B.F. Skinner (1950s) a. program that uses reinforcement (new information, choices, or point rewards) each time a student shows they learned something new b. program builds on information student has already mastered Token Economics 1. token economy: conditioning in which desirable behavior is reinforced with valueless objects, which can be accumulated and exchanged for valued rewards a. used in schools, prisons, mental hospitals, and halfway houses Self-Control 1. having people set up personal systems of rewards and punishments to shape their own thoughts and actions a. define the problem b. track the behavior c. set up a behavioral contract Improving Your Study Habits 1. progressively increase study quotas (successive approximations) a. remove conditioned aversive stimuli adjust to change or alter in order to fit or conform adapt A changing to fit new conditions menopause the biological event in which a woman's production of sex hormones is sharply reduced generativity the desire, in middle age, to use one's accumulated wisdom to guide future generations stagnation a discontinuation of development and a desire to recapture the past function the ability to achieve his or her goals within him or her self and the external environment. It includes an individual's behavior, emotion, social skills, and overall mental health assumed accepted as real or true without proof decremental model of aging idea that progressive physical and mental decline are inevitable with age ageism prejudice or discrimination against the elderly dementia decreases in mental abilities, which can be experienced by some people in old age Alzheimer's disease a condition that destroys a person's ability to think, remember, relate to others, and care for herself or himself component A part or element of a larger whole. isolating causing one to feel alone thanatology the study of death and dying hospice a facility designed to care for the special needs of the dying classical conditioning a learning procedure in which associations are made between a neutral stimulus and an unconditioned stimulus neural stimulus a stimulus that does not initially elicit any part of an unconditioned response unconditioned stimulus an event that elicits a certain predictable response typically without previous training unconditioned response an organism's automatic (or natural) reaction to a stimulus conditioned stimulus a once-neutral event that elicits a given response after a period of training in which it has been paired with an unconditioned stimulus conditioned response the learned reaction to a conditioned stimulus generalization responding similarly to a range of similar stimuli discrimination the ability to respond differently to similar but distinct stimuli extinction the gradual disappearance of a conditioned response when the conditioned stimulus is repeatedly presented without the unconditioned stimulus operant conditioning learning in which a certain action is reinforced or punished, resulting in corresponding increases or decreases in occurrence reinforcement stimulus or event that follows a response and increases the likelihood that the response will be repeated secondary reinforcer stimulus such as money that becomes rewarding through its link with a primary reinforce primary reinforcer stimulus that is naturally rewarding, such as food or water shaping technique in which the desired behavior is "molded" by first rewarding any act similar to that behavior and then requiring ever-closer approximations to the desired behavior before giving the reward response chain learned reactions that follow one another in sequence, each reaction producing the signal for the next aversive control process of influencing behavior by means of unpleasant stimuli negative reinforcement increasing the strength of a given response by removing or preventing a painful stimulus when the response occurs escape conditioning training of an organism to remove or terminate an unpleasant stimulus avoidance conditioning training of an organism to respond so as to prevent the occurrence of an unpleasant stimulus social learning process of altering behavior by observing and imitating the behavior of others cognitive learning form of altering behavior that involves mental processes and may result from observation or imitation cognitive map a mental picture of spatial relationships or relationships between events latent learning alteration of a behavioral tendency that is not demonstrated by an immediate, observable change in behavior learned helplessness condition in which repeated attempts to control a situation fail, resulting in the belief that the situation is uncontrollable modeling learning by imitating others; copying behavior token economy conditioning in which desirable behavior is reinforced with valueless objects, which can be accumulated and exchanged for valued rewards

Begin with limited knowledge: Given Facts and you must be able to answer “WHY” Given images and you must be able to recognize and classify This Course Hematology I – MLTS 207 Intro Red Cells Hematology II – MLTS 208 White Cells Coagulation Our Tool Safety First Standard Precautions PPE Hand washing Proper disposal Proper cleaning Know what to do in case of an emergency Fire Spill Needle stick QA vs QC Quality Assurance Comprehensive Preanalytical – Analytical - Post-analytical Ensures reliable patient results = positive outcome Quality Control is Analytical only – focuses on actual measurement of the analyte Quality Control Standards / Calibrators Controls Statistical quality control system Normals AKA Reference ranges Plt 150 – 450 X 103/ul Unique to analyte, method, instrument and patient population Delta Check Critical Values Blood Basics Average blood volume 4 – 6 liters Blood pH = 7.35 – 7.45 Components of whole blood 55% plasma - 44% RBCs - 1% WBCs and platelets (buffy coat) Red Blood Cell (Erythrocyte or RBC) White Blood Cell (Leukocyte or WBC) Platelets (Thrombocyte) Plasma is 91.5% water and 8.5% solutes Reference Ranges (patient normals) RBC 4.2 – 5.4 X 1012/L (106/ul) females 4.7 – 6.1 X 1012/L (106/ul) males WBC 5 – 10 X 109/L (103/ul) Platelets 150 – 450 X 109/L (103/ul) Blood Smears (Slides) Cells evaluated in an area where red cells are almost touching but do not overlap Smears can be made by hand or mechanically Smears are stained with Wright’s stain Smear is examined on 100X using oil to evaluate RBC morphology RBC Morphology Red cells are biconcave disk that are 7 – 8 um in diameter with a volume - 90fL (femtoliters) When stained they appear as: Circular cells with distinct smooth margins Dull pinkish hue Area of central pallor Fairly uniform in size No nucleus or inclusions Platelet Morphology Platelets are 2 – 4um in diameter and discoid shaped they contain reddish-purple granules in a small amount of bluish cytoplasm and have no nucleus Leukocytes Segmented neutrophils - AKA segs or PMN Band neutrophils Eosinophils Basophils Lymphocytes Monocytes Hematopoiesis Definition? Daily Production Quotas RBCs – 3 billion WBCs – 1.5 billion Plts – 2.5 billion Your body can: Constantly supply mature blood cells for circulation Mobilize Bone Marrow to increase production of a particular type of blood cell Compensate for decreased hematopoiesis by providing hematopoietic sites outside the BM The Beginning All blood cells are the progeny of hematopoietic pluriopotential stem cell In adults these are found in the bone marrow. Why? Monophyletic Theory A common precursor cell, the pluripotential stem cell, which under the influence of certain factors gives rise to each of the principle blood cell lines Cytokines - Pretty much universally accepted today based on clinical and experimental evidence and started with mice in 1961 Based on this theory, hematopoietic cells may be divided into 3 cellular catagories dependant on maturity 1 Multipotential stem cell able to self-renew and to differentiate into all blood cell lines 2 Committed progenitor cell destined to develop into distinct cell lines 3 Mature cells with specialized functions which have lost the capability to proliferate Hematopoietic Stem Cell Most important characteristic – must self renew Ability to differentiate into commited progenitor cells of lymphoid or myloid lineages Maturation Process (p.20) Hematopoiesis From Coception to Adulthood (p.16) Yolk Sac (embryonic hemoglobin) Begins 2 -3 weeks after fertilization and ceases after 8 – 10 weeks Fetal Liver (fetal hemoglobin) Production from about 2 – 7 months Liver is main site but spleen, thymus, lymph nodes, and kidney are also involved Bone Marrow – called medullary hematopoiesis Begins to function in 3rd month of gestation Primary site by the end of 5th month of gestation and continues after birth and throughout adulthood Children distal long bones Adults axial bones Extramedullary Hematopoiesis is hematopoiesis outside bone marrow Not a normal occurrence after 5th month of gestation Happens in certain disorders Occurs in liver and spleen Erythropoiesis Definition? Mature erythrocytes carry oxygen from the lungs to tissue where it is exchanged for CO2 Erythropoietin (a cytokine) Hormone produced by the kidney Stimulates red cell production Secreted daily in small amounts Kidney will sense hypoxia and secrete more if needed What happens when more EPO is secreted by the kidneys? Development of Red Cell Reduction in cell volume Condensation of chromatin (Loss of nucleoli) Decrease in N:C ratio (less nucleus – more cytoplasm) Decrease of RNA in cytoplasm Increased hemoglobin synthesis – to a point cell turns from blue to red Developmental Stages (images p33 - 35) Rubriblast (Pronormoblast) Each produces 8 – 16 mature red cells Stage where hemoglobin synthesis begins Prorubricyte (Basophilic Normoblast) Rubricyte (Polychromatophilic Normoblast) Last stage capable of division Large amounts of hemoglobin synthesized at this stage Metarubricyte (Orthochroimatophilic Normoblast) Nucleated Red Blood Cell (NRBC) seen on peripheral smear Reticulocyte (Polychromatophilic Erythrocyte) Non-nucleated (nucleus extruded) Contains residual RNA and mitochondria which gives cell bluish tinge with Wright’s stain Last stage to synthesize hemoglobin Part of this phase occurs in the bone marrow, later part takes place in circulating blood Mature Erythrocyte Stains pink because of large amount of hemoglobin No RNA or mitochondria = no synthesizing of proteins or lipids Normal lifespan 120 days Have You Seen Your Spleen Fist shaped organ located on the left side under the rib cage Blood filled organ consisting of Red pulp – red cell filtration Cull old or abnormal RBCs (Reticuloedothelial System) Pit RBC inclusions Remove Antibodies - spherocytes White pulp – lymphocyte processing Marginal zone – WBC & Plt storage 1/3 population of each Bone Marrow not Bowel Movement One of the largest organs in the body Inside you find erythroid cells, myloid cells, and megakaryocytes in various stages of development – stem cells, fatty tissue, osteoclasts, etc. As you age marrow in long bones is replaced by fat Adult marrow in iliac crest and sternum. M:E ratio -Myeloid to erythroid ratio Normally 3-4:1 Why are there more myloid cells in the bone marrow and more RBCs in circulation?
