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 (fair division), entitlement to them so that each person receives their due share. The central tenet of fair division is that such a division should be performed by the players themselves, without the need for external arbitration, as only the players themselves really know how they value the goods. There are many different kinds of fair division problems, depending on the nature of goods to divide, the criteria for fairness, the nature of the players and their preferences, and other criteria for evaluating the quality of the division. The archetypal fair division algorithm is divide and choose. The research in fair division can be seen as an extension of this procedure to various more complex settings. Description In game theory, fair division is the problem of dividing a set of resources among several people who have an Entitlement (fair division), entitlem ...

Strike Action
Strike action, also called labor strike, labour strike in British English, or simply strike, is a work stoppage caused by the mass refusal of employees to Working class, work. A strike usually takes place in response to 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 the r ... [...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 a process whereby natural selection favours a trait due to its positive effects on the reproductive success of an organism's relatives, even when at a cost to the organism's own survival and reproduction. Kin selection can lead to the evolution of altruistic behaviour. It is related to inclusive fitness, which combines the number of offspring produced with the number an individual can ensure the production of by supporting others (weighted by the relatedness between individuals). A broader definition of kin selection includes selection acting on interactions between individuals who share a gene of interest even if the gene is not shared due to common ancestry. 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 all ...

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. 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 Commission, 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 being a collective bargaining agreement. The methods can be cla ...

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 ( resignation), 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 employe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economy
An economy is an area of the Production (economics), production, Distribution (economics), distribution and trade, as well as Consumption (economics), consumption of Goods (economics), goods and Service (economics), 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 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 agr ...

Trade Union
A trade union (British English) or labor union (American English), often simply referred to as a union, is an organization of workers whose purpose is to maintain or improve the conditions of their employment, such as attaining better wages and Employee benefits, benefits, improving Work (human activity), working conditions, improving safety standards, establishing complaint procedures, developing rules governing status of employees (rules governing promotions, just-cause conditions for termination) and protecting and increasing the bargaining power of workers. Trade unions typically fund their head office and legal team functions through regularly imposed fees called ''union dues''. The union representatives in the workforce are usually made up of workplace volunteers who are often appointed by members through internal democratic elections. The trade union, through an elected leadership and bargaining committee, bargains with the employer on behalf of its members, known as t ...

Psychology
Psychology is the scientific study of mind and behavior. Its subject matter includes the behavior of humans and nonhumans, both consciousness, conscious and Unconscious mind, unconscious phenomena, and mental processes such as thoughts, feelings, and motivation, motives. Psychology is an academic discipline of immense scope, crossing the boundaries between the Natural science, natural and social sciences. Biological psychologists seek an understanding of the Emergence, emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.Hockenbury & Hockenbury. Psychology. Worth Publishers, 2010. A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as Behavioural sciences, behavioral or Cognitive science, cognitive scientists.

Tit For Tat
Tit for tat is an English saying meaning "equivalent retaliation". It is an alternation of '' tip for tap'' "blow for blow", 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. This is similar to reciprocal altruism in biology. 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. Few have extended the game theoretical approach to other applications such as finance. In that context the tit for tat strategy was shown to be associated to the trend following strategy. Implicatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
