Social identity threat is a theory in social psychology derived from social identity theory to explain the different types of threats that arise from group identity being threatened as opposed to personal identity. [1]
A Tsirelson bound is an upper limit to quantum mechanical correlations between distant events. Given that quantum mechanics violates Bell inequalities (i.e., it cannot be described by a local hidden-variable theory), a natural question to ask is how large can the violation be.
Using the anticommutators of the gamma matrices, one can show that for any and , / / = = / / + / / =. where is the identity matrix in four dimensions.. In particular, / =. Further identities can be read off directly from the gamma matrix identities by replacing the metric tensor with inner products.
Psychology and Communication scholars study the relationship between social media and identity in order to understand individual behavior, psychological impact, and social patterns. [ 1 ] [ 2 ] [ 3 ] Communication within political or social groups online can result in practice application of those identities or adoption of them as a whole.
The dominant players in the field, called the incumbents, are generally invested in maintaining the field in its current form, as changes to the rules of competition risk destabilizing their dominant position. [2] Fields may also feature insurgents who instead aim to alter the field so they can successfully compete with the incumbents. [3]
A high-ranking male mandrill advertises his status with bright facial coloration. [1]In the zoological field of ethology, a dominance hierarchy (formerly and colloquially called a pecking order) is a type of social hierarchy that arises when members of animal social groups interact, creating a ranking system.
The Blank Slate: The Modern Denial of Human Nature is a best-selling 2002 book by the cognitive psychologist Steven Pinker, in which the author makes a case against tabula rasa models in the social sciences, arguing that human behavior is substantially shaped by evolutionary psychological adaptations.
John Clive Ward, FRS (1 August 1924 – 6 May 2000) was an Anglo-Australian physicist who made significant contributions to quantum field theory, condensed-matter physics, and statistical mechanics. Andrei Sakharov called Ward one of the titans of quantum electrodynamics. Ward introduced the Ward–Takahashi identity.
