Mutualism (biology)
Mutualism describes the ecological Biological interaction, interaction between two or more species where each species has a net benefit. Mutualism is a common type of Ecology, ecological interaction. Prominent examples are: * the nutrient exchange between vascular plants and mycorrhizal fungi, * the Fertilisation, fertilization of flowering plants by pollinators, * the ways plants use fruits and edible seeds to encourage animal aid in seed dispersal, and * the way corals become photosynthetic with the help of the microorganism zooxanthellae. Mutualism can be contrasted with interspecific competition, in which each species experiences ''reduced'' fitness, and Cheating (biology), exploitation, and with parasitism, in which one species benefits at the expense of the other. However, mutualism may evolve from interactions that began with imbalanced benefits, such as parasitism. The term ''mutualism'' was introduced by Pierre-Joseph van Beneden in his 1876 book ''Animal Parasites an ...

Mutualism (economic Theory)
Mutualism is an anarchist school of thought and economic theory that advocates for workers' control of the means of production, a free market made up of individual artisans, sole proprietorships and workers' cooperatives, and occupation and use property rights. As proponents of the labour theory of value and labour theory of property, mutualists oppose all forms of economic rent, profit and non-nominal interest, which they see as relying on the exploitation of labour. Mutualists seek to construct an economy without capital accumulation or concentration of land ownership. They also encourage the establishment of workers' self-management, which they propose could be supported through the issuance of mutual credit by mutual banks, with the aim of creating a federal society. Mutualism has its roots in the utopian socialism of Robert Owen and Charles Fourier. It first developed a practical expression in Josiah Warren's community experiments in the United States, which he est ...

Mutualism (movement)
Mutualism, also known as the movement of mutuals and the mutualist movement, is a social movement that aims at creating and promoting mutual organizations, mutual insurances and mutual funds. According to the prominent mutualist Gene Costa, the movement encourages and assists the provision of mutual benefits against risks to those accessing its funds and or the elevation of their material and spiritual living standards by regular payment or contribution. Institutionalized through mutual funds, mutualism has been universally recognized as a generator or embryo of classical forecast and modern social security systems and currently coexists with them. Although the fall in the popularity of mutual funds in many social environments coincided with the start of public social security system in the early decades of the 20th century, in Europe and other parts of the world mutualism continues to be an important player in the social economy. Mutuals providing healthcare coverage are united ...

G Factor (psychometrics)
The ''g'' factor is a construct developed in psychometric investigations of Cognitive skill, cognitive abilities and human intelligence. It is a variable that summarizes positive correlations among different cognitive tasks, reflecting the assertion that an individual's performance on one type of cognitive task tends to be comparable to that person's performance on other kinds of cognitive tasks. The ''g'' factor typically accounts for 40 to 50 percent of the between-individual performance differences on a given cognitive test, and composite scores ("IQ scores") based on many tests are frequently regarded as estimates of individuals' standing on the ''g'' factor.Kamphaus et al. 2005 The terms ''Intelligence quotient, IQ, general intelligence, general cognitive ability, general mental ability'', and simply ''intelligence'' are often used interchangeably to refer to this common core shared by cognitive tests.Deary et al. 2010 However, the ''g'' factor itself is a mathematical constr ...
