Here’s your revised and organized notes: ⸻ Main Causes of the Boom WWI • Took place 1914-1918. • America joined in 1917. • Sold products to Britain and allies throughout the war. • Loaned money to Britain and allies, which was later used to buy war supplies from the USA. • America took over production due to disruptions in Europe. • No post-war destruction in the USA. • More jobs for soldiers when they returned. Government Policies • Republican government helped businesses. • Fordney-McCumber Tariff Act: Placed a tariff on goods imported from abroad. • Encouraged Americans to purchase American goods. • Tax cuts for the rich so more jobs could be created. • More money to buy consumer goods. New Ways to Buy and Sell • Advertising: billboards, magazines, newspapers. • Catalogs: people living in rural America could buy consumer goods. • Hire purchase plan: Spread out costs over a long period of time. Consumer Society • Americans became obsessed with buying things. • Advertisements encouraged people to spend their paychecks on new items, boosting the economy. • Benefited wealthier people, as they had more access to electrical products. Mass Production • Goods were not made by a single person but by many people on a conveyor line. • Ford invented it in 1913 to make his Model T car, which got cheaper every year. • 1925 price of the car: $290 (instead of the earlier $850). • Meant employees had to be trained for only one job on the line. • Goods were produced quickly and in bulk, making them cheaper and increasing profits. • Business owners benefited as they could mass-produce products faster and in better working conditions. ⸻ How Were Their Lives Affected? Factory Workers (Cotton & Wool) • Did not benefit. • Less demand for their products due to man-made fibers such as rayon. • Fashion used less fabric. • Prices fell, factories closed, and people were laid off. • Economic effects: drop in employment. African Americans (Did Not Benefit) • Sharecroppers had to give a portion of their land as rent. • Farmers lost out as there was a much lower demand for food after Europe began to redevelop. • Many Black people without jobs were unable to get new ones due to institutional racism. • Economic and social disadvantages. Farmers (Did Not Benefit) • Europe recovered and didn’t require American crops, leading to high unemployment. • 600,000 people unemployed. • High-tech meant more food was produced, lowering production costs but also leading to oversupply. • Economic struggles as they couldn’t sell goods to Europe, which was self-sufficient. • Combine harvesters and tractors allowed for greater production but didn’t help struggling farmers. ⸻ This structure makes it easier to follow and connects the causes of the boom with its effects

4. Metals and Non-metals Learning Objectives By the end of the lesson, you will be able to: ☑ distinguish between metals and non-metals ☑ describe the physical and chemical properties of metals and non-metals ☑ list the uses of some metals and non-metals MINERALS AND ORES You have learnt that all materials Here is the exact text from the image:are made up of basic substances called elements, and that elements cannot be split into simpler substances by chemical methods. There are 118 known elements. Sodium, zinc, gold, mercury, iron, lead, barium and tin (metals); and hydrogen, oxygen, carbon, sulphur, chlorine, boron, neon and radon (non-metals) are some examples. Only certain unreactive elements are found free in nature. Others occur in combined states as minerals. A mineral is a solid inorganic substance that is found in nature. A mineral deposit that can be mined and from which an element or compound can be obtained profitably is known as an ore. Elements can be broadly classified into two groups—metals and non-metals. Table 4.1 Some common ores Fig. 4.1 Some common ores a. Bauxite (aluminium) b. Malachite (copper) c. Haematite (iron) d. Galena (lead) e. Apatite (phosphorus) f. Quartz (silicon) -- --- METALS All except 20 of the known elements are metals. Most metals are reactive; they combine with other elements in nature, such as oxygen and sulphur, and occur as oxides, sulphides and carbonates. Only a few unreactive metals like gold, silver and platinum are found as free metals in the Earth's crust. Physical Properties of Metals Metals are solids at room temperature, except mercury, which is a liquid at room temperature (Fig. 4.2(a)). They are generally hard and strong, with a few exceptions such as sodium and potassium, which are soft and can be easily cut with a knife (Fig. 4.2(b)). They have a metallic lustre (shine), especially when freshly cut. They have high melting and boiling points, with a few exceptions like sodium, potassium and mercury. They are good conductors of heat and electricity. Silver and copper are the best conductors of electricity, followed by gold and aluminium. Metals are sonorous. They produce a ringing sound when struck. Most metals have high tensile strength. They can take heavy loads without breaking. They are malleable. Metals, with exceptions like sodium and potassium, can be beaten into thin sheets and foils. They are ductile. Metals, with exception like sodium and potassium, can be drawn into wires. Most metals have high density. However, sodium and potassium have low density and float on water. Fig. 4.2 Special metals a. Mercury b. Sodium --- Chemical Properties of Metals Reaction with oxygen Metals react with oxygen under different conditions to form basic oxides. These basic oxides react with water to form bases. Sodium and potassium react vigorously with oxygen at room temperature. 4Na + O_2 \rightarrow 2Na_2O To prevent this oxidation, sodium and potassium are stored under kerosene. Magnesium reacts with oxygen only when ignited. It burns with a dazzling bright flame and forms a white powder of magnesium oxide. 2Mg + O_2 \rightarrow 2MgO Copper and iron react with oxygen only when heated to a very high temperature. 2Cu + O_2 \rightarrow 2CuO --- --- Reaction with water Metals react with water to form hydroxides or oxides, along with hydrogen. Different metals react at different temperatures. Sodium, potassium, and calcium react with cold water to form hydroxides. 2Na + 2H_2O \rightarrow 2NaOH + H_2 Magnesium Reacts with steam or hot water to form magnesium oxide. Mg + H_2O \rightarrow MgO + H_2 Aluminium Forms an oxide too, but this oxide forms a protective covering over the metal and prevents further reactions. 2Al + 3H_2O \rightarrow Al_2O_3 + 3H_2 Zinc Reacts only with steam. Zn + H_2O \rightarrow ZnO + H_2 Iron Reacts with steam when heated strongly. 2Fe + 3H_2O \rightarrow Fe_3O_4 + 3H_2 Copper, gold, silver, and platinum do not react with water at all. --- Activity 4.1 Teacher Demonstration Aim: To study the reaction of metals with water. [Caution: This activity should be demonstrated by the teacher, and students should stand away from the table.] Materials required: Two 200 mL beakers Pieces of sodium and calcium Forceps Knife Litmus papers Water Method: 1. Fill each beaker with 100 mL of water. 2. Using forceps and a knife, cut a small piece of sodium. 3. Dry it on a tissue paper and drop it into one of the beakers. 4. Repeat the same procedure with calcium. 5. Test the water in both the beakers with red and blue litmus papers. Observations and Conclusions: Sodium reacts vigorously and may explode. A gas is also released. The reaction with calcium is quick, though not as vigorous as that with sodium. In both cases, the red litmus paper turns blue, showing that the solutions are bases. --- Reaction with dilute acids Most metals react with dilute acids to form their salts and liberate hydrogen gas. The reaction with reactive metals like sodium, potassium, and calcium is violent. Magnesium, aluminium, zinc, and iron do not react violently. Mg + 2HCl \rightarrow MgCl_2 + H_2 Copper, silver, gold, and platinum do not react with dilute acids. --- Reaction with bases Only some metals such as aluminium and zinc react with strong bases like sodium hydroxide to liberate hydrogen gas. Zn + 2NaOH \rightarrow Na_2ZnO_2 + H_2 --- Activity 4.2 Aim: To study the reaction of metals with dilute hydrochloric acid. Materials required: Sandpaper Six test tubes Dilute hydrochloric acid Strips of magnesium, zinc, iron, tin, lead, and copper Method: 1. Clean the metal strips with sandpaper. 2. Add dilute hydrochloric acid to the six test tubes. 3. Insert a strip of metal into each test tube. Observe if any bubbles are formed in the test tubes. If no bubbles are seen, warm them gently in a beaker of hot water. 4. Observe the speed at which gas is generated. This gives an idea of the speed of the reaction. 5. Classify the metals in order of their reactivity with dilute hydrochloric acid. [Caution: Acids are corrosive and should be handled carefully.] --- Activity 4.3 Aim: To study the reaction of metals with bases. Materials required: Small piece of zinc Beaker Sodium hydroxide Method: 1. Prepare warm sodium hydroxide or caustic soda solution. 2. Drop the piece of zinc into it. Observations and Conclusions: You will notice that zinc reacts with sodium hydroxide to liberate hydrogen gas. Observations on Metals with Dilute Acids Metals like sodium, potassium, and calcium react violently with dilute acids to liberate hydrogen gas. Magnesium, aluminium, zinc, and iron also displace hydrogen from dilute acids, but the reaction is not violent. Metals such as copper, silver, gold, and platinum do not displace hydrogen from dilute acids. --- Activity Series of Metals The activity series of metals is the arrangement of metals in decreasing order of reactivity. The series in the book shows reactivity decreasing from top to bottom. Potassium is the most reactive metal while gold is the least reactive. --- Displacement of a Metal by Other Metals A more reactive metal displaces a less reactive metal from its compounds in an aqueous solution. Some examples: Mg + CuSO_4 \rightarrow MgSO_4 + Cu Zn + FeSO_4 \rightarrow ZnSO_4 + Fe Iron can displace copper from copper sulphate solution (as shown in Activity 4.4). The solution turns green, and reddish-brown copper deposits on the iron nail. Copper cannot displace iron from iron sulphate solution, showing that copper is less reactive than iron. Cu + FeSO_4 \rightarrow \text{No reaction} Question: What do you think will happen if you place a silver spoon in copper sulphate solution? --- Activity 4.4 - Displacement Reaction Aim: To study a displacement reaction. Materials Required: Test tube Iron nail Copper sulphate solution Method: 1. Fill the test tube with copper sulphate solution (blue in colour). 2. Place the clean iron nail in the solution. Observations and Conclusions: After about an hour, the solution changes to green, and a reddish-brown deposit is formed on the iron nail. --- Corrosion of Metals Corrosion is the destruction or damage of a material due to chemical reaction. Rusting of iron happens when iron is exposed to moist air, forming a reddish-brown layer of rust. Rust is iron oxide, which eventually flakes off, damaging the object. Definition written on the page: "Slow eating of a metal’s surface due to oxidation is called corrosion of metals." --Observations on Metals with Dilute Acids Metals like sodium, potassium, and calcium react violently with dilute acids to liberate hydrogen gas. Magnesium, aluminium, zinc, and iron also displace hydrogen from dilute acids, but the reaction is not violent.

Definition written on the page: "Slow eating of a metal’s surface due to oxidation is called corrosion of metals." Uses of Metals (Continued) Aluminium Used in high-voltage electric lines. Alloys like duralumin and magnalium are used in aircraft and automobile bodies. Used for making aluminium foil and cooking utensils. Copper Good conductor of electricity → Used in electrical wires, cables, motors, and transformers. Good conductor of heat → Used in the bottoms of stainless steel vessels. Zinc Used to make corrosion-resistant galvanised iron (GI) pipes and sheets. Used as an electrode in dry cells. Other Metals Gold and silver → Used in jewellery. Lead → Used in electrodes of lead storage batteries (used in automobiles and inverters). Chromium → Used for electroplating iron to give a shiny, corrosion-resistant finish. --- Looking Back (True/False Statements) 1. Gold, silver, and platinum are found in the Earth’s crust as free metals. → True 2. Most metals are solids that are soft. → False 3. Metals such as zinc and magnesium react with dilute acids to liberate oxygen. → False 4. A less reactive metal displaces a more reactive metal from its aqueous solution. → False 5. The chemical name of rust is zinc oxide. → False (Rust is Fe₂O₃.xH₂O) 6. Coating zinc objects with iron is called galvanising. → False (Galvanising is coating iron with zinc) Non-Metals Physical Properties of Non-Metals Exist as gases or solids at room temperature (except bromine, which is liquid). Not as hard as metals (except diamond, which is very hard). Low tensile strength and low density. Low melting and boiling points (except graphite). Not sonorous (do not produce a ringing sound). Not malleable or ductile (cannot be beaten into sheets or drawn into wires). Do not have lustre (except iodine and graphite). Bad conductors of heat and electricity (except graphite, and silicon under specific conditions). --Chemical Properties of Non-Metals Reaction with Water Most non-metals do not react with water. Highly reactive non-metals (e.g., phosphorus) catch fire in air, so they are stored in water. Fluorine, chlorine, and bromine react with water to form acids. Reaction with Oxygen Non-metals react with oxygen to form acidic or neutral oxides. Carbon and sulfur react with oxygen to form acidic oxides, which dissolve in water to form acids. Some oxides (e.g., CO, N₂O) are neutral and do not form acids. Examples: Carbon + Oxygen → Carbon Dioxide (CO₂) CO₂ + Water → Carbonic Acid (H₂CO₃) Sulfur + Oxygen → Sulfur Dioxide (SO₂) SO₂ + Water → Sulfurous Acid (H₂SO₃) Reaction with Acids Unlike metals, non-metals do not replace hydrogen in acids. Silicon reacts with hydrofluoric acid (HF). --Uses of Non-Metals Hydrogen Used in the manufacture of ammonia and industrial chemicals. Used in vanaspati (a cooking oil). Oxygen Used in breathing support systems in hospitals. Used with other gases in equipment to weld metals. Sulphur Used in the manufacture of sulphuric acid, sulphur dioxide gas, and other industrial chemicals. Used to make pesticides for agriculture. Used in vulcanising rubber (making it harder) and in gunpowder. Nitrogen Used in the manufacture of ammonia and nitrogenous fertilisers like ammonium nitrate and ammonium sulphate. Used as an inert gas in processed food packaging to prevent rancidity. Silicon Used in making semiconductors for microchips. Silicates (oxides of silicon) are used in making glass. Other Non-Metals Phosphorus: Used in making fertilisers (superphosphates). Chlorine: Used for disinfecting drinking water. Argon: Used in welding stainless steel and filling electric bulbs. Helium: Used in balloons for meteorological observations. Neon: Used in fluorescent lights for advertisement displays

Apple/Samsung, etc.. pour assurer que leur application a été le défaut sur leur produit, ce qui réduit la compétition beaucoup. 1.6 Avantage concurrentiel 4x exemples d'avantage concurrentiel durable. - 6x exemples d'avantage concurrentiel nondurable. - Soit prêt avec des exemples d' entreprises/produits qui utilisent les avantages spécifiques. Développer un produit ou service Unique - Quand une entreprise a quelque chose que les entreprises concurrentes n'ont pas et ne sont pas susceptibles de développer. Par exemple, Canva est unique, car les utilisateurs n'ont pas besoin d'une expérience significative comme designer graphique. Réduire les couts de production L'utilisation de systèmes de fabrication rentables, d'automation et de haute technologie peuvent aider avec ceci. Par exemple, le Tesla déplace la production en Chine pour élimer les couts et les tarifs automobiles. Vendres a un marché niche Une entreprise fournit un produit ou un service pour un marché spécifique et dépasse la concurrence. (Il n'y a pas assez de compétition à ce marché niche). Par exemple le Drunk Éléphant Cosmetics, qui met l'accent sur les ingrédients propres et non toxiques. Créer la fidélisation de la clientèle Établir des relations avec les clients qui vont au-delà de la commodité et de prix pour que le client n'envisage pas une autre option. Par exemple, Apple garde ses clients file-les grâce à ses appareils connectés, ses services exclusifs et la qualité de ses produits. NON-DURABLE : Promotions Les entreprises veulent essayer de créer une priorité pour leur produit pour être considérés avant tous les autres par ajuster leur prix. (Ex. Ventes, coupons, programmes d'appréciations des clients). McDonald's 1$ crème glacées, les réductions/ventes à Walmart. Partenariats Exclusifs Les P/contrats exclusifs avec des fournisseurs/distributeurs ou célébrités sont très bonne, mais une fois que le contrat expire ou que les concurrents trouvent d'autres arrangements, l'avantage diminuent. (Par exemple, Nike x Travis Scott, Apple x RED). Qualité Un produit doit être plus fort, rapide, léger, facile à utiliser etc.... Alors les entreprises doivent toujours ajouter les nouvelles innovations/fonctionnalités. Par exemple, le Toyota Corolla améliore leur qualité de produit avec le système Kaizen pour augmenter la qualité et efficacité. Aussi les versions d'iPhone pour Apple. Bénéfices d'Usage Les avantages que le consommateur expérience quand ils utilisent un produit ou service, ce qui le rend plus attrayant pour eux. -Par exemple, l'Apple Watch qui a plusieurs fonctionnalités. Prix Le prix et seulement un avantage si le produit ou le service a des qualités égales à celle de la concurrence. Cela peut être difficile à maintenir avec l'évolution du marché. Par exemple le Prix de Netflix qui sont très compétitifs avec l'émergence des autres services de diffusion comme Disney+ ou Apple TV, Prime, etc.... Caracteristiques du Design Les concurrents peuvent rapidement reproduire ou innover sur les caractéristiques, ce qui réduit leur unicité et impacte au fil du temps. Par exemple, La Nintendo Switch a la capacité unique de fonctionner comme une console personnelle et un appareil portable. 1.4 Profil du client - Décrit: les données démographiques, psychographiques et géographiques. - Soit prêt avec des exemples pour chacun. Démographiques : Les donnes démographiques incluses des faits objectives des personnes comme leur âge, genre, classe socio-économique, ou niveau d'éducation/emplois. Psychographiques : Les donnes psychographiques incluses des faits subjectives des personnes, comme leur personnalité, valeurs ou intérêts. Géographiques : Les donnes géographiques incluses des faits lie à les locations, pays, villes et plus en relation des consommateurs en question. 1.5 Les marchés concurrentiels - Pourquoi la concurrence est-elle importante pour vendre des produits et des services? - Concurrence directe et indirecte. - Concurrence parfaite, monopole, oligopole. - Le clé d'efficacité nécessaire pour être concurrentiel avec exemple d'une entreprise. - Décrire prix prédateur et pratique anticoncurrentielle. Explique pratique anticoncurrentielle avec une exemple de leçon. → La concurrence est essentielle pour réduire les prix et offrir plusieurs options aux consommateurs, parce que les entreprises vont être en compétition et vont essayer d'offrir des prix/produits/services plus en plus compétitif pour rester relevant et continuer à faire un produit. Ça va aussi pousser les compagnies à innover constamment pour donner des meilleures p/s a leurs consommateurs. Concurrence Directe : La concurrence directe implique les entreprises qui offrent les services ou produits très similaires, par exemple Hershey's et Dairy Milk (les deux sont de la chocolat). Concurrence Indirecte : La concurrence indirecte implique les entreprises qui offrent les services ou produits différents, mais qui ciblent et attire le même marché et les mêmes clients, Par exemple, Uber Eats et Dominos. Concurrence Parfaite: La concurrence parfaite implique beaucoup de petites entreprises, avec aucune qui on contrôle du marché ciblent. Par exemple, Etsy, Les Barbiers, et les massothérapeutes. Concurrence Monopole : La concurrence monopole implique une seule entreprise qui est le seul fournisseur d'un bien ou service, et par conséquence, créé une situation ou seulement une entreprise a du contrôle complète sur le marché. (Chartwells, Via Rail, Canada Post, Enbridge) Concurrence Oligopole : La concurrence oligopole existe quand il y a un petit nombre de grandes entreprises dans la situation, et chacun a un peu de contrôle sur le marché. (Les banques CIBC/TD etc, Services de téléphone Bell/Rogers, Services de diffusion comme Netflix/Disney Plus). Efficacité : L'efficacité comprennent de trois aspects majeurs : a) Une GRANDE QUANTITÉ de produits ou services (Amazon a des millions de produits) b) Une HAUTE QUALITÉ de produits ou services (Les Apple produits sont de haute qualité. c) Réduire des RESSOURCES utilisées. (Starbucks commence à utiliser l'automation pour leurs processus = moins employés) → Les prix prédateurs est lorsqu'une entreprise dominante dans une industrie réduit délibérément ses prix de produit/service à des niveaux déficits (alors ne fait pas du profit) à court terme pour amasser des clients et être compétitif. → Les pratiques anticoncurrentielles sont lorsqu'un concurrent essaye de forcer d'autres concurrents à sortir d'un marché ou rend la marche plus difficile a entre. (Par exemple, les signatures d'offres exclusives avec des fournisseurs de produits, qui barre les autres entreprises de l'accès.) Par exemple, en 2024, Google a face des allégations de PA dans les États-Unis à cause de leur monopole sur l'industrie de recherche/navigateurs. Google a payé des compagnies comme 1.0 Emplois et cheminement de carrière Quels sont les emplois de cheminement de carrière (selon le site web au diapos de 1.0). - Marketing de médias sociaux Marketing par courrier Électronique Gestion de la Marque Marketing de Contenu et Rédaction Commercialisation des produits Analyse de Marketing et Marketing de Croissance - RP/Communications - Marketing Événementiel SEO/SEM et E-Commerce 1.1 Les principes de marketing - Quels sont les 3 types d'entreprises? Offre des explications et des exemples. Les produits industriels et les produits de consommations: Offre des explications et des exemples Services industriels et les services de consommateurs: Offre des explications et des exemples - Quelles sont les idées clés qui décrivent le concept de Marketing? Fabricants abricants utilisent la commercialisation de leurs produits quils sont typiquement créent eux-mêmes. Entreprise de Service : Les entreprises de services, commercialisent leurs services et leur expertise à leurs consommateurs. Organisations sans but Lucratif : Les organisations sans but lucratif veulent promouvoir leur cause aux donations, potentielle et leurs avantages aux clients. →Produits Industriels Utiliser pour fabriquer d'autres produits pou pour aider les opérations commerciales. (Ex. Maniérés primaires, Produits qui sont transformés) Ex. Parties de voiture, huile, bois. → Produits De Consommations Sont des produits non industriels pour les usages personnels par le grand public. (Ex. les téléphones cellulaires, l'iPhone, les pupitres). 1.3 Qu'est-ce qui motive un client? - Quelles sont les 5 motivations qui encouragent les ventes parmi les consommateurs? Offre des explications et des exemples. → Services Industriels Utiliser par des entreprises en raison d'augmenter ou ajouter des aspects à leurs opérations/procès etc... (Ex. Google donne des services personnalisé de Google Cloud a des entreprises pour augmenter l'efficacité de l'entreprise). -Services De Consommateurs Utiliser par des clients individuels pour leur vie personnels. (Par exemple, Google offre l'application de Google Cloud pour que leurs consommateurs puissent augmenter leur productivité.) 1. Les Besoins et Désirs Il y a une pyramide de besoin et désirs qui influence et motive les clients. Pour vouloir quelque chose plus haut dans la pyramide, les besoins et désirs des niveaux avant ce niveau ont besoin d'être présent dans ta vie. Besoins physiologiques, besoins de sécurité, besoin d'appartenance, besoin d'estime, besoins d'accomplir. 2. Influences Sociales Amis, familles et médias sociaux ainsi que des tendances et normes sociales peuvent influence et motiver des clients. 3. Commodité et Accessibilité Facile à trouver et acheter, ainsi que simple à utiliser et maintenir (par exemple l'Apple, qui est facile à acheter et maintenir à cause de son design simple). 4. Perception et Identité Les consommateurs veulent exprimer leurs identités, valeurs, personnalité et pus avec les marques, services et produits qu'ils utilisent. (Par exemple, porter le Lululemon démontre ton intérêt en être actif ou ta position comme moyenne-haute classe.) 5. Valeur Perçu Les consommateurs veulent des produits/service qui ont la qualité, fonctionnalité et prix bons dans la perception/perspective. (Ex. une artiste choisira le Faber-Castell aux dessous du Crayola à cause de la qualité)

● Unique Corporate Culture: Zappos integrates happiness and motivation into its core principles, providing exceptional benefits and maintaining a flat organizational structure to enhance employee motivation and satisfaction. Motivational Strategies: The company emphasizes personal connections in customer interactions, offers substantial training with an option to quit, and focuses on creating a fulfilling work environment, reflecting a deep commitment to employee happiness and motivation. —--------------------------------------- Overview of Early Motivation Studies: ● Early motivation studies focused on understanding how individual needs drive employees to demonstrate goal-oriented behavior in order to satisfy these needs. For instance, an employee seeking companionship might frequently engage in conversations around the office to fulfill this need. Key Theories of Motivation: 1. Maslow’s Hierarchy of Needs: ○ Developed by Abraham Maslow, this theory posits that human needs are organized hierarchically from the most basic to higher-level needs. ○ Levels of Needs: ■ Physiological Needs: Basic survival needs like food and water. ■ Safety Needs: Protection from danger and stability. ■ Social Needs: Desire for relationships and belonging. ■ Esteem Needs: Need for respect, recognition, and self-esteem. ■ Self-Actualization: The pursuit of realizing one’s full potential and engaging in activities that lead to growth and fulfillment. ○ Maslow’s theory suggests that once a lower-level need is satisfied, it ceases to be a motivator, and the individual moves to satisfy higher-level needs. 2. ERG Theory (Clayton Alderfer): ○ This theory modifies Maslow’s hierarchy by categorizing needs into three groups: ■ Existence Needs: Corresponds to Maslow’s physiological and safety needs. ■ Relatedness Needs: Links to social needs. ■ Growth Needs: Encompasses esteem and self-actualization needs. ○ ERG theory does not maintain a strict hierarchy and acknowledges that multiple needs can be motivational at the same time. It introduces the concept of “frustration-regression, ” where individuals revert to satisfying lower-level needs if they cannot satisfy higher-level ones. 3. Herzberg’s Two-Factor Theory: ○ Frederick Herzberg identified two sets of factors that impact motivation: ■ Hygiene Factors: Elements like company policies, salary, and working conditions, which can cause dissatisfaction if not addressed. ■ Motivators: Factors intrinsic to the job such as achievement, recognition, and growth opportunities, which truly motivate employees to perform better. ○ Herzberg argued that improving hygiene factors alone does not increase job satisfaction; instead, motivators are crucial for enhancing employee motivation. 4. McClelland’s Acquired-Needs Theory: ○ David McClelland proposed that individuals develop certain needs based on their life experiences, which are: ■ Need for Achievement: Desire to excel and achieve in relation to a set of standards. ■ Need for Affiliation: Desire for friendly and close interpersonal relationships. ■ Need for Power: Desire to make an impact, influence others, and have authority. ○ The dominant need influences an individual’s behavior at work and their suitability for certain roles. For example, high achievement needs are effective in roles with clear performance metrics, while high affiliation needs are beneficial in cooperative roles. Applications and Implications: ● ● Understanding these needs and theories helps managers create work environments that satisfy employee needs, thus motivating them effectively. The theories emphasize the importance of recognizing the diversity of employee needs and tailoring motivational approaches accordingly. Critiques and Limitations: ● ● While these theories have been influential, they also face criticisms such as the rigidity of need hierarchy (Maslow) and the oversimplification of motivational factors (Herzberg). Despite criticisms, these theories provide valuable frameworks for understanding employee motivation and designing effective management practices. Here’s a detailed summary of the process-based theories of motivation, as outlined in your text: Overview of Process-Based Theories of Motivation: ● Process-based theories view motivation as a rational process where individuals analyze their environment, develop thoughts and feelings, and react accordingly. This perspective focuses on understanding the cognitive processes that underpin motivated behavior. Equity Theory (Adams, 1965): ● ● ● ● ● Core Concept: People are motivated by fairness, which they assess through social comparisons of input-outcome ratios with others (referents). Inputs and Outcomes: Inputs are contributions (e.g., effort, skill), while outcomes are what people receive in return (e.g., pay, recognition). Perceptions of Equity: Fairness is perceived when one’s ratio of input to outcome matches that of their referent. Responses to Inequity: Responses can include altering perceptions, changing the input level, adjusting outcomes, or even leaving the situation. Overpayment and Underpayment: Reactions differ based on whether individuals feel over-rewarded or under-rewarded, influencing their motivation and actions. Expectancy Theory (Vroom, 1964; Porter & Lawler, 1968): ● ● Core Concept: Motivation is determined by an individual’s rational calculation of expectancy (effort will lead to performance), instrumentality (performance will lead to outcomes), and valence (value of the outcomes). Application: This theory is useful for understanding how beliefs about the relationships between effort, performance, and rewards motivate people to act in certain ways. Reinforcement Theory: ● ● ● Core Concept: Behavior is shaped by its consequences, either reinforcing desired behaviors or discouraging undesired ones. Types of Reinforcement: ○ Positive Reinforcement: Increases desirable behavior by offering positive outcomes. ○ Negative Reinforcement: Increases behavior by removing negative conditions. ○ Punishment: Decreases undesired behavior through negative consequences. ○ Extinction: Reduces behavior by removing rewards. Reinforcement Schedules: Different schedules (continuous, fixed-ratio, variable-ratio) affect the durability and quality of behavior changes. Procedural and Interactional Justice: ● Beyond distributive justice (fairness of outcomes), procedural (fairness of processes used to determine outcomes) and interactional justice (treatment of individuals in the enactment of procedures) are crucial in shaping perceptions of fairness and, consequently, motivation. OB Toolbox for Fairness: ● Recommendations include recognizing diverse contributions, ensuring fairness in decision-making, treating people with respect, and maintaining transparency in rules and decisions. Organizational Behavior Modification (OB Mod): ● A systematic application of reinforcement theory in organizations to modify employee behaviors. It involves identifying behaviors, measuring baseline levels, analyzing antecedents and consequences, implementing interventions, and evaluating outcomes. Key Success Factors: 1. 2. 3. Employee Empowerment: Employees at Nucor are treated as company owners, empowered to make decisions and take actions that affect their work and the company’s operations directly. Decentralized Structure: Authority and responsibility are pushed down to lower levels, allowing line workers to undertake tasks typically reserved for management. Innovative Reward System: Nucor’s compensation strategy includes high base wages, significant annual bonuses, and profit sharing, with a strong link to company and individual performance. Modern Approaches to Job Design: ● ● ● Job Rotation: This involves periodically shifting employees to different tasks to alleviate monotony and enhance skills. Job Enlargement: Expands job tasks to add variety and increase employee engagement and satisfaction. Job Enrichment: Provides more autonomy over how tasks are performed, increasing responsibility and potentially improving job satisfaction and productivity. Job Characteristics Model (Hackman & Oldham, 1975): Identifies five core job dimensions that impact three critical psychological states, influencing job outcomes: 1. Skill Variety 2. Task Identity 3. Task Significance 4. Autonomy 5. Feedback These dimensions contribute to feelings of meaningfulness, responsibility, and understanding of results, leading to high internal work motivation, job satisfaction, and reduced absenteeism. Empowerment: ● Extends the concept of autonomy by removing barriers that limit the potential of ● ● employees. Structurally empowered employees, who are provided with information, resources, and support to make decisions, tend to have higher job satisfaction and performance. Effective empowerment also requires a supportive management and organizational culture that genuinely delegates decision-making power to employees. Summary: Motivating Employees Through Goal Setting Goal-Setting Theory: Goal-setting is a powerful method of motivation, supported by extensive research showing that effectively set goals can enhance employee performance significantly. This approach has been broadly adopted across various sectors, including major corporations globally. SMART Goals: Effective goals are SMART—Specific, Measurable, Aggressive, Realistic, and Time-bound: ● ● ● Specific and Measurable: Goals should be clear and quantifiable to ensure performance can be evaluated accurately. Aggressive: Goals should be challenging to stimulate higher performance. Realistic: While goals should be ambitious, they must also be achievable to maintain motivation. ● Time-Bound: A clear timeline increases urgency and helps focus efforts. Why SMART Goals Motivate: Goals clarify the direction and energize employees towards achieving specific outcomes. They also encourage innovative thinking to meet challenging targets and create a sense of accomplishment upon achieving these goals. Conditions for Effective Goals: ● ● ● Feedback: Regular feedback helps align employee's efforts with their goals. Ability: Employees need the requisite skills and knowledge to achieve their goals. Goal Commitment: Commitment to goals is crucial for their effectiveness, which can be enhanced by involving employees in the goal-setting process and ensuring the goals align with their values and capabilities. Potential Downsides of Goal Setting: ● ● Goals can reduce adaptability to changing circumstances if too rigid. Overemphasis on specific goals can lead to neglect of other important duties or unethical behavior to achieve targets. Summary: Motivating Employees Through Performance Appraisals Overview: Performance appraisals are a formal process used by organizations to assess and provide feedback on employee performance. These appraisals are crucial for employee motivation, informing decisions on rewards, promotions, and terminations. Key Features of Effective Appraisals: Effective appraisals are characterized by: ● ● ● Adequate Notice: Employees are informed about the criteria ahead of time. Fair Hearing: Appraisals include two-way communication. Evidence-Based Judgment: Decisions are based on documented performance evidence. When properly managed, performance appraisals are valuable tools for motivating employees, enhancing their development, and aligning their goals with organizational objectives. Effective appraisals require clear criteria, fair processes, and regular feedback to truly benefit both employees and the organization. Summary: Motivating Employees Through Performance Incentives Incentive Systems Overview: Incentive systems link employee pay to performance, either on an individual or company-wide basis. Common in many organizations, these systems are designed to implement motivation theories practically, aiming to boost productivity, profits, and employee commitment through various forms of financial rewards. Types of Incentives: 1. 2. 3. 4. 5. 6. 7. 8. Piece Rate Systems: Compensation is based on the quantity of output produced. Effective in environments where output is easily measurable. Individual Bonuses: One-time rewards for achieving specific goals, enhancing motivation by providing clear, achievable targets. Merit Pay: Ongoing pay raises based on past performance, typically determined through performance appraisals. Can lead to a sense of entitlement if not carefully managed. Sales Commissions: Compensation linked to the volume or profitability of sales. Needs careful structuring to align with company goals and encourage desirable behaviors. Team Bonuses: Rewards based on team performance, suitable in environments where teamwork and collective performance are critical. Gainsharing: Rewards employees for performance improvements over previous periods, typically through cost savings or efficiency gains, fostering a culture of continuous improvement. Profit Sharing: Distributes a portion of company profits among employees, fostering loyalty and a sense of ownership among staff. Stock Options: Provides employees the option to buy company stock at a future date at a predetermined price, aligning employee interests with those of the company. Effectiveness and Challenges: While financial incentives can be powerful motivators, they also have potential downsides such as promoting risk-averse behavior and diminishing creativity. Incentives may also lead employees to focus narrowly on rewarded behaviors, potentially at the expense of other important duties or organizational citizenship behaviors. Key Considerations for Effective Incentives: ● ● ● Incentives should be clearly aligned with organizational goals and strategies. The structure of incentives should balance between encouraging desired behaviors and allowing flexibility to adapt to changing circumstances. Companies should be aware of the potential for incentives to encourage unethical behavior or excessive risk-taking. Conclusion: Properly designed and implemented, performance incentives can significantly enhance motivation and performance. However, they require careful management to ensure they support broader organizational objectives and promote a healthy, collaborative, and innovative work culture. Overview of Trait Approaches: Early leadership studies focused on identifying traits that distinguish leaders from non-leaders, exploring various personality characteristics and physical attributes. Although initially deemed inconclusive, modern research, particularly with the advent of the Big Five personality framework, has successfully linked certain traits with leadership capabilities. Key Leadership Traits: 1. Intelligence: Both general mental ability (IQ) and emotional intelligence (EQ) are associated with leadership emergence and effectiveness. EQ's role becomes critical in managing oneself and interpersonal relationships effectively. 2. Big Five Personality Traits: ○ Extraversion: Strongly correlated with leadership emergence and effectiveness; extraverts' sociability and assertiveness make them visible leader candidates. ○ Conscientiousness: Organized and persistent traits contribute to leadership emergence and effectiveness. ○ Openness to Experience: Creativity and openness to new experiences are linked to innovative leadership. 3. Self-Esteem: High self-esteem enhances an individual's self-confidence and leadership perception. 4. Integrity: Honesty and moral integrity are crucial for leaders to maintain trustworthiness and ethical standards. Limitations of Trait Approaches: Trait approaches initially failed to consider situational contexts which can significantly influence leadership effectiveness. The recognition of this limitation led to a more nuanced understanding that the effectiveness of certain traits may depend heavily on specific organizational contexts or scenarios. Application in Modern Leadership: Understanding the impact of these traits helps in selecting and developing effective leaders. It’s recognized that the relevance of specific traits can vary, depending on the organizational context and the specific demands of the leadership role. Conclusion: Trait theories have evolved to highlight the importance of both identifying essential leadership traits and understanding the situational factors that influence the effectiveness of these traits in various leadership contexts. This dual focus aids in the more targeted development and placement of leaders within organizations. Leader Decision Making: Leaders use various decision-making styles, which include: 1. 2. Authoritarian: The leader makes decisions unilaterally. Democratic: Employees participate in the decision-making process. 3. Laissez-Faire: The leader provides minimal guidance and allows employees to make decisions independently. The effectiveness of these styles varies based on the organizational context and the specific situation, with democratic styles generally increasing employee satisfaction but not necessarily impacting productivity significantly. Laissez-faire leadership is often negatively associated with employee satisfaction and effectiveness. Leadership Assumptions about Human Nature: Douglas McGregor’s Theory X and Theory Y outline two opposing perceptions of employee motivation: ● Theory X: Assumes employees are inherently lazy and require strict supervision and ● control. Theory Y: Views employees as self-motivated and responsive to tasks that are satisfying and fulfilling. Leaders' assumptions about human nature can influence their management style, with Theory Y leaders tending to be more supportive and empowering. Limitations of Behavioral Approaches: Behavioral approaches to leadership are criticized for their failure to consider the context in which leadership occurs. What works in one organizational setting might not work in another, indicating the necessity for leaders to adapt their behaviors to the specific demands and culture of their organization. Key Takeaway: Behavioral approaches highlight the importance of leaders’ actions and their decision-making styles in influencing their effectiveness and the satisfaction of their teams. These approaches also underscore the need for adaptability in leadership practices, reflecting the varying needs of different organizational environments. ● ● ● ● ● Contingency Leadership Context: Leadership effectiveness varies with the situation; no single style is universally effective. Fiedler’s Contingency Theory: Categorizes leaders as task-oriented or relationship-oriented. Effectiveness depends on the match between a leader's style and situational favorableness, influenced by leader-member relations, task structure, and leader's power. Situational Leadership Theory (SLT): Proposes adjusting leadership style based on follower readiness, combining directive and supportive behaviors to meet follower development needs. Path-Goal Theory: Based on expectancy theory of motivation, leaders facilitate employee paths to goals by adjusting their behaviors (directive, supportive, participative, achievement-oriented) to fit employee and task characteristics. Vroom and Yetton’s Normative Decision Model: Guides leaders on the level of employee involvement in decision-making based on several situational variables, offering a range from autocratic to delegative styles. ● Overall Insight: Contingency theories emphasize adapting leadership styles to the context, follower characteristics, and specific organizational circumstances for optimal leadership effectiveness. Here’s a summarized version in bullet points: ● ● ● ● ● ● ● ● ● Transformational vs. Transactional Leadership: ○ Transformational leaders align employee goals with their own, focusing on the company's well-being. ○ Transactional leaders manage through clear structures and rewards for performance. Tools of Transformational Leaders: ○ Charisma: Inspire and garner admiration from followers. ○ Inspirational Motivation: Provide a compelling vision of the future. ○ Intellectual Stimulation: Encourage innovation and creativity. ○ Individualized Consideration: Offer personal attention and mentorship. Transactional Leadership Methods: ○ Contingent Rewards: Provide tangible rewards for tasks completed. ○ Active Management by Exception: Proactively prevent problems. ○ Passive Management by Exception: Intervene only when standards are not met. Effectiveness: ○ Transformational leadership is often more effective, enhancing motivation, performance, and satisfaction. ○ Transactional styles also show effectiveness, particularly when excluding passive management by exception. Trust and Leadership: ○ Transformational leaders are likely to be trusted more because they show concern for followers and communicate values effectively. Can Charisma Be Trained?: ○ Charisma isn't solely innate; it can be developed despite being somewhat influenced by personality traits like extraversion and neuroticism. Dark Side of Charisma: ○ Charisma can lead to blind allegiance, potentially harming organizations if not accompanied by other solid leadership qualities. Leader-Member Exchange (LMX) Theory: ○ Focuses on the type of relationship leaders form with individual members. ○ High-quality LMX relationships result in mutual trust, respect, and obligation. ○ Benefits include greater job satisfaction, performance, and organizational commitment. Developing High-Quality LMX: ○ Leaders can foster high-quality exchanges by being fair, dignified, and trusting. ○ Employees can enhance relationships through seeking feedback, being open to learning, and showing initiative. These points outline the core elements of contemporary approaches to leadership, emphasizing the situational effectiveness of different leadership styles and the importance of leader-member relationships. Week 5: Motivation Instructor: Dr. Kevin Leung Key Concepts: 1. What is Motivation? ○ Definition: A set of energetic forces that originates both within and outside an individual, initiates work-related effort, and determines its direction, intensity, and persistence. 2. Components of Motivation: ○ Direction: Focuses on the goals towards which effort is directed. ○ Intensity: Measures how hard a person tries. ○ Persistence: Examines how long a person can maintain effort. 3. Theoretical Perspectives in Studying Motivation: ○ Need Theories: What motivates people through understanding their needs. ○ Process Theories: How motivation occurs through interactions within the environment. 4. Need Theories: ○ Maslow’s Hierarchy of Needs: Sequential needs from physiological to self-actualization. ○ Alderfer’s ERG Theory: Simplifies Maslow’s into three core needs: Existence, Relatedness, and Growth. ○ Herzberg’s Two-Factor Theory: Distinguishes between Motivators (satisfaction) and Hygiene factors (dissatisfaction). ○ McClelland’s Theory of Social Motives: Focuses on Achievement, Power, and Affiliation. 5. Process Theories: ○ Behavioral Theories: Emphasizes the role of reinforcement. ○ Cognitive Choice Theories: Centers on decision-making processes like Expectancy Theory. ○ Self-Regulation Theories: Includes Goal Setting Theory advocating for SMART goals. Need Theories: ● ● Understand the basic needs outlined in Maslow’s Hierarchy (from physiological needs at the base to self-actualization at the top) and how each level motivates behavior. Recognize that only unsatisfied needs motivate. Alderfer’s ERG Theory condenses Maslow’s into three groups: Existence, Relatedness, and Growth, which can be pursued simultaneously and can regress based on frustration. ● ● Herzberg’s Two-Factor Theory differentiates between Hygiene factors (which prevent dissatisfaction but don't motivate) and Motivators (which truly drive employees to perform better). McClelland’s Theory focuses on the needs for Achievement, Affiliation, and Power. Unlike Maslow’s, these needs are not in any order and can vary in intensity between individuals. Process Theories: ● Expectancy Theory: Effort leads to performance (Expectancy), performance leads to outcomes (Instrumentality), and outcomes are valued (Valence). Understanding the connections between these elements helps predict employee motivation to engage in a behavior. Goal Setting Theory: ● Goals must be SMART—specific enough to clarify what is expected, measurable to gauge progress, achievable yet challenging, relevant to the individual’s role, and time-bound with a deadline. Goals effectively direct attention, mobilize effort, enhance persistence, and promote the development of strategies and action plans. Week 6: Leadership Instructor: Dr. Kevin Leung Key Concepts: 1. Introduction to Leadership: ○ Definition: The process of influencing others towards the achievement of goals. 2. Theoretical Perspectives on Leadership: ○ Trait Approach: Identifies personality traits that distinguish leaders. ○ Behavioral Approach: Observes behaviors that are effective for leadership. 3. Contingency Theories: ○ Fiedler’s Contingency Model: Matches leader’s style with the situation to optimize effectiveness. ○ House’s Path-Goal Theory: Adjusts leadership behavior to employee and environmental needs. 4. Contemporary Approaches to Leadership: ○ Transformational Leadership: Focuses on visionary, inspiring, and change-inducing behaviors. ○ Transactional Leadership: Relies on exchanges and rewards to influence employee behaviors. 5. Charismatic and Servant Leadership: ○ ○ Charismatic Leadership: Relies on the leader’s magnetic personality to influence and inspire followers. Servant Leadership: Prioritizes the needs of others and aims to serve rather than lead in the traditional sense. Info for Quiz Preparation: ● ● ● ● Motivation Lecture: Understand the specific components of each theory, particularly how they explain the direction, intensity, and persistence of motivation. Leadership Lecture: Be able to distinguish between different leadership styles and theories, especially noting how transformational leaders differ from transactional ones and the specific conditions under which each leadership style might be most effective according to contingency theories. Expectancy Theory in Process Theories: Focus on how expectancy (effort leads to performance), instrumentality (performance leads to outcomes), and valence (value of the outcomes) interact to motivate behavior. Goal Setting Theory: Understand how setting SMART (Specific, Measurable, Achievable, Relevant, Time-bound) goals can directly influence motivation and performance, supporting with examples if possible. These notes are organized to aid in understanding complex psychological theories by breaking them down into their core components, crucial for preparing for quizzes that may test comprehension and application of these concepts. ● ● ● Differences between Transformational and Transactional Leadership: ○ Transformational Leaders: Inspire and motivate employees to exceed normal levels of performance through charismatic leadership styles, visionary, and stimulating approaches. They focus on changing existing perceptions and motivating followers to put group or organizational interests first. ○ Transactional Leaders: Focus on maintaining the normal flow of operations using a system of rewards and penalties. They are practical and traditional, ensuring that staff follow procedures and perform their designated tasks. ○ Effective Conditions: Transformational leadership is effective in dynamic and competitive environments that require innovation and change. Transactional leadership works well in stable environments where tasks are routine, and the primary goal is efficiency. Expectancy Theory in Process Theories: ○ Dive deeper into how employees weigh the perceived costs and benefits of making an effort. An employee's motivation to perform is increased if they believe that their effort will lead to good performance (Expectancy), that good performance will be rewarded (Instrumentality), and that they will find the reward satisfactory (Valence). Goal Setting Theory: ● ● ○ Specific goals increase performance; difficult goals, when accepted, result in higher performance than easy goals; feedback enhances the effect of specific and difficult goals. This is because specific and challenging goals focus attention and foster a persistent effort, leading to the development of effective strategies. Additional Insights For Expectancy Theory, prepare to apply scenarios where employees might perceive high or low expectancy, instrumentality, and valence, and predict their motivation outcomes
