Cooperation
Cooperation (written as co-operation in British English) is the process of groups of organisms working or acting together for common, mutual, or some underlying benefit, as opposed to working in competition for selfish benefit. Many animal and plant species cooperate both with other members of their own species and with members of other species (symbiosis or mutualism). Among humans Humans cooperate for the same reasons as other animals: immediate benefit, genetic relatedness, and reciprocity, but also for particularly human reasons, such as honesty signaling (indirect reciprocity), cultural group selection, and for reasons having to do with cultural evolution. Language allows humans to cooperate on a very large scale. Certain studies have suggested that fairness affects human cooperation; individuals are willing to punish at their own cost (''altruistic punishment'') if they believe that they are being treated unfairly. Sanfey, et al. conducted an experiment where 19 ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kin Selection
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 Altruism in animals, 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 Halda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cooperative
A cooperative (also known as co-operative, co-op, or coop) is "an autonomous association of persons united voluntarily to meet their common economic, social and cultural needs and aspirations through a jointly owned and democratically-controlled enterprise".Statement on the Cooperative Identity. ''.'' Cooperatives are democratically controlled by their members, with each member having one vote in electing the board of directors. Cooperatives may include: * businesses owned and managed by the people who consume th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collective Action
Collective action refers to action taken together by a group of people whose goal is to enhance their condition and achieve a common objective. It is a term that has formulations and theories in many areas of the social sciences including psychology, sociology, anthropology, political science and economics. The social identity model Researchers Martijn van Zomeren, Tom Postmes, and Russell Spears conducted a meta-analysis of over 180 studies of collective action, in an attempt to integrate three dominant socio-psychological perspectives explaining antecedent conditions to this phenomenon – injustice, efficacy, and identity. In their resultant 2008 review article, an integrative Social Identity Model of Collective Action (SIMCA) was proposed which accounts for interrelationships among the three predictors as well as their predictive capacities for collective action. An important assumption of this approach is that people tend to respond to subjective states of disadvantage, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Competition
Competition is a rivalry where two or more parties strive for a common goal which cannot be shared: where one's gain is the other's loss (an example of which is a zero-sum game). Competition can arise between entities such as organisms, individuals, economic and social groups, etc. The rivalry can be over attainment of any exclusive goal, including Recognition (sociology), recognition: Competition occurs in nature, between living organisms which co-exist in the same natural environment, environment. Animals compete over water supplies, food, mates, and other resource (biology), biological resources. Humans usually Survival of the fittest, compete for food and mates, though when these needs are met deep rivalries often arise over the pursuit of wealth, power, prestige, and celebrity, fame when in a static, repetitive, or unchanging environment. Competition is a major tenet of market economy, market economies and business, often associated with business competition as companies a ...

Cultural Group Selection
Cultural group selection is an explanatory model within cultural evolution of how cultural traits evolve according to the competitive advantage they bestow upon a group. This multidisciplinary approach to the question of human culture engages research from the fields of anthropology, behavioural economics, evolutionary biology, evolutionary game theory, sociology, and psychology. While cultural norms are often beneficial to the individuals who hold them, they need not be. Norms can spread by cultural group selection when they are practiced within successful groups, and norms are more likely to spread from groups that are successful. But, for cultural group selection to occur, there must exist, between groups, cultural differences that when transmitted across time affect the persistence or proliferation of the groups.Campbell, D.T.

Inclusive Fitness
In evolutionary biology, inclusive fitness is one of two metrics of evolutionary success as defined by W. D. Hamilton in 1964: * Personal fitness is the number of offspring that an individual begets (regardless of who rescues/rears/supports them) * Inclusive fitness is the number of offspring equivalents that an individual rears, rescues or otherwise supports through its behaviour (regardless of who begets them) An individual's own child, who carries one half of the individual's genes, is defined as one offspring equivalent. A sibling's child, who will carry one-quarter of the individual's genes, is 1/2 offspring equivalent. Similarly, a cousin's child, who has 1/16 of the individual's genes, is 1/8 offspring equivalent. From the gene's point of view, evolutionary success ultimately depends on leaving behind the maximum number of copies of itself in the population. Prior to Hamilton's work, it was generally assumed that genes only achieved this through the number of viable off ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Selfish
Selfishness is being concerned excessively or exclusively, for oneself or one's own advantage, pleasure, or welfare, regardless of others. Selfishness is the opposite of altruism or selflessness; and has also been contrasted (as by C. S. Lewis) with self-centeredness. Divergent views The implications of selfishness have inspired divergent views within religious, philosophical, psychological, economic, and evolutionary contexts. Classical Aristotle joined a perceived majority of his countrymen in condemning those who sought only to profit themselves; but he approved the man of reason who sought to gain for himself the greatest share of that which deserved social praise. Seneca proposed a cultivation of the self within a wider community—a care for the self which he opposed to mere selfishness in a theme that would later be taken up by Foucault. Medieval/Renaissance Selfishness was viewed in the Western Christian tradition as a central vice—as standing at the roots of the se ...

Mutualism (biology)
Mutualism describes the ecological interaction between two or more species where each species has a net benefit. Mutualism is a common type of ecological interaction. Prominent examples include most vascular plants engaged in mutualistic interactions with mycorrhizae, flowering plants being pollinated by animals, vascular plants being dispersed by animals, and corals with zooxanthellae, among many others. Mutualism can be contrasted with interspecific competition, in which each species experiences ''reduced'' fitness, and exploitation, or parasitism, in which one species benefits at the expense of the other. The term ''mutualism'' was introduced by Pierre-Joseph van Beneden in his 1876 book ''Animal Parasites and Messmates'' to mean "mutual aid among species". Mutualism is often conflated with two other types of ecological phenomena: cooperation and symbiosis. Cooperation most commonly refers to increases in fitness through within-species (intraspecific) interactions, althoug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultimatum Game
The ultimatum game is a game that has become a popular instrument of economic experiments. An early description is by Nobel laureate John Harsanyi in 1961. One player, the proposer, is endowed with a sum of money. The proposer is tasked with splitting it with another player, the responder. Once the proposer communicates his decision, the responder may accept it or reject it. If the responder accepts, the money is split per the proposal; if the responder rejects, both players receive nothing. Both players know in advance the consequences of the responder accepting or rejecting the offer. Equilibrium analysis For ease of exposition, the simple example illustrated above can be considered, where the proposer has two options: a fair split, or an unfair split. The argument given in this section can be extended to the more general case where the proposer can choose from many different splits. There are two strategies available to the proposer: propose a fair split, or propose an un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Communities
A community is a Level of analysis, social unit (a group of living things) with commonality such as place (geography), place, Norm (social), norms, religion, values, Convention (norm), customs, or Identity (social science), identity. Communities may share a sense of place (geography), place situated in a given geographical area (e.g. a country, village, town, or neighbourhood) or in virtual space through communication platforms. Durable good relations that extend beyond immediate genealogical ties also define a sense of community, important to their identity, practice, and roles in social institutions such as family, home, work, government, society, or humanity at large. Although communities are usually small relative to personal social ties, "community" may also refer to large group affiliations such as nation, national communities, international community, international communities, and virtual community, virtual communities. The English-language word "community" derives from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Team
A team is a group of individuals (human or non-human) working together to achieve their goal. As defined by Professor Leigh Thompson (academic), Leigh Thompson of the Kellogg School of Management, "[a] team is a group of people who are interdependent with respect to information, resources, knowledge and skills and who seek to combine their efforts to achieve a common goal". A group does not necessarily constitute a team. Teams normally have members with complementary skills and generate synergy through a coordinated effort which allows each member to maximize their strengths and minimize their weaknesses. Naresh Jain (2009) claims: Team members need to learn how to help one another, help other team members realize their true self, true potential, and create an environment that allows everyone to go beyond their limitations. While academic research on teams and teamwork has grown consistently and has shown a sharp increase over the past recent 40 years, the societal diffusio ...

Teamwork
Teamwork is the collaborative effort of a group to achieve a common goal or to complete a task in the most effective and efficient way. This concept is seen within the greater framework of a team, which is a group of interdependent individuals who work together towards a common goal. The four key characteristics of a team include a shared goal, interdependence, boundedness and stability, the ability to manage their own work and internal process, and operate in a bigger social system. Basic requirements for effective teamwork are an adequate team size. The context is important, and team sizes can vary depending upon the objective. A team must include at least 2 or more members, and most teams range in size from 2 to 100. Sports teams generally have fixed sizes based upon set rules, and work teams may change in size depending upon the phase and complexity of the objective. Teams need to be able to leverage resources to be productive (i.e. playing fields or meeting spaces, sch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
