Researchers who use the concept mainly do so to explain how men uphold men's dominance in society. [1] Homosocial was popularized by Eve Kosofsky Sedgwick in her discussion of male homosocial desire.

A typical triple bond, for example in acetylene (HC≡CH), consists of one sigma bond and two pi bonds in two mutually perpendicular planes containing the bond axis. Two pi bonds are the maximum that can exist between a given pair of atoms. Quadruple bonds are extremely rare and can be formed only between transition metal atoms, and consist of ...
Problematic Integration is a type of message-processing communication theory that relates to theories of decision making and persuasion. Problematic Integration Theory (PI) proposes that: (1) people orient themselves to the world by forming both probabilistic and evaluative orientations; (2) that probability and evaluation are not independent from one another; (3) that probability and ...
A social relation is the fundamental unit of analysis within the social sciences, and describes any voluntary or involuntary interpersonal relationship between two or more conspecifics within and/or between groups. [1]
The Social Construction of Reality: A Treatise in the Sociology of Knowledge (1966), by Peter L. Berger and Thomas Luckmann, proposes that social groups and individual persons who interact with each other, within a system of social classes, over time create concepts (mental representations) of the actions of each other, and that people become habituated to those concepts, and thus assume ...
