Spite (game Theory)
In fair division problems, spite is a phenomenon that occurs when a player's value of an allocation decreases when one or more other players' valuation increases. Thus, other things being equal, a player exhibiting spite will prefer an allocation in which other players receive less than more (if more of the good is desirable). In this language, spite is difficult to analyze because one has to assess two sets of preferences. For example, in the divide and choose method, a spiteful player would have to make a trade-off between depriving his opponent of cake, and getting more himself. Within the field of sociobiology, spite is used to describe those social behaviors that have a negative impact on both the actor and recipient(s). Spite can be favored by kin selection when: (a) it leads to an indirect benefit to some third party that is sufficiently related to the actor (Wilsonian spite); or (b) when it is directed primarily at negatively related individuals (Hamiltonian spite).

Fair Division
Fair division is the problem in game theory of dividing a set of resources among several people who have an entitlement to them so that each person receives their due share. That problem arises in various real-world settings such as division of inheritance, partnership dissolutions, divorce settlements, electronic frequency allocation, airport traffic management, and exploitation of Earth observation satellites. It is an active research area in mathematics, economics (especially social choice theory), dispute resolution, etc. The central tenet of fair division is that such a division should be performed by the players themselves, maybe using a mediator but certainly not an arbiter as only the players really know how they value the goods. The archetypal fair division algorithm is divide and choose. It demonstrates that two agents with different tastes can divide a cake such that each of them believes that he got the best piece. The research in fair division can be seen as an exten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strike Action
Strike action, also called labor strike, labour strike, or simply strike, is a work stoppage caused by the mass refusal of employees to Labor (economics), work. A strike usually takes place in response to grievance (labour), employee grievances. Strikes became common during the Industrial Revolution, when Labour economics, mass labor became important in factories and mines. As striking became a more common practice, governments were often pushed to act (either by private business or by union workers). When government intervention occurred, it was rarely neutral or amicable. Early strikes were often deemed unlawful conspiracies or anti-competitive cartel action and many were subject to massive legal repression by state police, federal military power, and federal courts. Many Western nations legalized striking under certain conditions in the late 19th and early 20th centuries. Strikes are sometimes used to pressure governments to change policies. Occasionally, strikes destabilize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spite (sentiment)
Spite or spitefulness as a sentiment, action, or a personality trait has several possible meanings. According to the American Psychological Association there is "no standard definition of spitefulness. Spite can be broadly defined to include any vindictive or mean-spirited actions. Alternatively, a narrower definition includes the requirement that spiteful acts involve some degree of self-harm." One possible definition of spite is to intentionally annoy, hurt, or upset even when there might be no (apparent) gain, and even when those actions might cause the person spiting harm, as well. ''Spiteful'' words or actions are delivered in such a way that it is clear that the person is delivering them just to annoy, hurt, or upset. In his 1929 examination of emotional disturbances, ''Psychology and Morals: An Analysis of Character'', J. A. Hadfield uses deliberately spiteful acts to illustrate the difference between disposition and sentiment. Spite has also been studied as a trait of ...

Hamilton's Rule
Kin selection is the evolutionary strategy that favours the reproductive success of an organism's relatives, even when at a cost to the organism's own survival and reproduction. Kin altruism can look like altruistic behaviour whose evolution is driven by kin selection. Kin selection is an instance of inclusive fitness, which combines the number of offspring produced with the number an individual can ensure the production of by supporting others, such as siblings. Charles Darwin discussed the concept of kin selection in his 1859 book, ''On the Origin of Species'', where he reflected on the puzzle of sterile social insects, such as honey bees, which leave reproduction to their mothers, arguing that a selection benefit to related organisms (the same "stock") would allow the evolution of a trait that confers the benefit but destroys an individual at the same time. R.A. Fisher in 1930 and J.B.S. Haldane in 1932 set out the mathematics of kin selection, with Haldane famously joking ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Appeal To Spite
An appeal to spite (Latin: ''argumentum ad odium'') is a form of argumentation which attempts to win favor by exploiting feelings of bitterness, spite, or schadenfreude in the audience. Logically fallacious, it attempts to sway the audience emotionally by associating a widely hated figure or concept with the opposition's argument. Appeal to spite is similar to ad hominem arguments which attack the speaker rather than addressing the claims, but in this case the ill feeling is not created by the argument, it already exists. Examples * "Why shouldn't prisoners do hard labor? The places are full of scumbags!" * "Stop that recycling! Aren't we tired of Hollywood celebrities preaching about saving the Earth?" * "Why should they In Modern English, ''they'' is a third-person pronoun relating to a grammatical subject. Morphology In Standard Modern English, ''they'' has five distinct word forms: * ''they'': the nominative (subjective) form * ''them'': the accusat ... ev ...

Union Organizer
A union organizer (or union organiser in Commonwealth spelling) is a specific type of trade union member (often elected) or an appointed union official. A majority of unions appoint rather than elect their organizers. In some unions, the organizer's role is to recruit groups of workers under the organizing model. In other unions, the organizer's role is largely that of servicing members and enforcing work rules, similar to the role of a shop steward. In some unions, organizers may also take on industrial/legal roles such as making representations before Fair Work Australia, tribunals, or courts. In North America, a union organizer is a union representative who "organizes" or unionizes non-union companies or worksites. Organizers primarily exist to assist non-union workers in forming chapters of locals, usually by leading them in their efforts. Methodology Organizers employ various methods to secure recognition by the employer as being a legitimate union, the ultimate goal ...

Termination Of Employment
Termination of employment or separation of employment is an employee's departure from a job and the end of an employee's duration with an employer. Termination may be voluntary on the employee's part, or it may be at the hands of the employer, often in the form of dismissal (firing) or a layoff. Dismissal or firing is usually thought to be the employee's fault, whereas a layoff is generally done for business reasons (for instance, a business slowdown or an economic downturn) outside the employee's performance. Firing carries a stigma in many cultures and may hinder the jobseeker's chances of finding new employment, particularly if they have been terminated from a previous job. Jobseekers sometimes do not mention jobs from which they were fired on their resumes; accordingly, unexplained gaps in employment, and refusal or failure to contact previous employers are often regarded as "red flags". Dismissal Dismissal is when the employer chooses to require the employee to leave, us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economy
An economy is an area of the production, distribution and trade, as well as consumption of goods and services. In general, it is defined as a social domain that emphasize the practices, discourses, and material expressions associated with the production, use, and management of scarce resources'. A given economy is a set of processes that involves its culture, values, education, technological evolution, history, social organization, political structure, legal systems, and natural resources as main factors. These factors give context, content, and set the conditions and parameters in which an economy functions. In other words, the economic domain is a social domain of interrelated human practices and transactions that does not stand alone. Economic agents can be individuals, businesses, organizations, or governments. Economic transactions occur when two groups or parties agree to the value or price of the transacted good or service, commonly expressed in a certain currency. Ho ...

Trade Union
A trade union (labor union in American English), often simply referred to as a union, is an organization of workers intent on "maintaining or improving the conditions of their employment", ch. I such as attaining better wages and benefits (such as holiday, health care, and retirement), improving working conditions, improving safety standards, establishing complaint procedures, developing rules governing status of employees (rules governing promotions, just-cause conditions for termination) and protecting the integrity of their trade through the increased bargaining power wielded by solidarity among workers. Trade unions typically fund their head office and legal team functions through regularly imposed fees called ''union dues''. The delegate staff of the trade union representation in the workforce are usually made up of workplace volunteers who are often appointed by members in democratic elections. The trade union, through an elected leadership and bargaining committee, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychology
Psychology is the scientific study of mind and behavior. Psychology includes the study of conscious and unconscious phenomena, including feelings and thoughts. It is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Psychologists seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.Fernald LD (2008)''Psychology: Six perspectives'' (pp.12–15). Thousand Oaks, CA: Sage Publications.Hockenbury & Hockenbury. Psychology. Worth Publishers, 2010. Ψ (''psi''), the first letter of the Greek word ''psyche'' from which the term psychology is derived (see below), is commonly associated with the science. A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as behavioral or cognitive scientists. Some psyc ...

Tit For Tat
Tit for tat is an English saying meaning "equivalent retaliation". It developed from "tip for tap", first recorded in 1558. It is also a highly effective strategy in game theory. An agent using this strategy will first cooperate, then subsequently replicate an opponent's previous action. If the opponent previously was cooperative, the agent is cooperative. If not, the agent is not. Game theory Tit-for-tat has been very successfully used as a strategy for the iterated prisoner's dilemma. The strategy was first introduced by Anatol Rapoport in Robert Axelrod's two tournaments, held around 1980. Notably, it was (on both occasions) both the simplest strategy and the most successful in direct competition. An agent using this strategy will first cooperate, then subsequently replicate an opponent's previous action. If the opponent previously was cooperative, the agent is cooperative. If not, the agent is not. This is similar to reciprocal altruism in biology. History The term develo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iterated Prisoner's Dilemma
The Prisoner's Dilemma is an example of a game analyzed in game theory. It is also a thought experiment that challenges two completely rational agents to a dilemma: cooperate with their partner for mutual reward, or betray their partner ("defect") for individual reward. This dilemma was originally framed by Merrill Flood and Melvin Dresher while working at RAND in 1950. Albert W. Tucker appropriated the game and formalized it by structuring the rewards in terms of prison sentences and named it "prisoner's dilemma". William Poundstone in his 1993 book ''Prisoner's Dilemma'' writes the following version:Two members of a criminal gang are arrested and imprisoned. Each prisoner is in solitary confinement with no means of speaking to or exchanging messages with the other. The police admit they don't have enough evidence to convict the pair on the principal charge. They plan to sentence both to two years in prison on a lesser charge. Simultaneously, the police offer each prisoner a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
