In mathematics, especially in linear algebra and matrix theory, the duplication matrix and the elimination matrix are linear transformations used for transforming half-vectorizations of matrices into vectorizations or (respectively) vice versa.
The matrix of domination or matrix of oppression is a sociological paradigm that explains issues of oppression that deal with race, class, and gender, which, though recognized as different social classifications, are all interconnected.
Social reproduction, when co-opted with cultural reproduction, allows for sociology of education to assume its role. [2] Education is an attempt at leveling the playing field by allowing those in poorer classes a chance to move up .
For example, for the 2×2 matrix = [], the half-vectorization is = []. There exist unique matrices transforming the half-vectorization of a matrix to its vectorization and vice versa called, respectively, the duplication matrix and the elimination matrix .
Analytical sociology is a strategy for understanding the social world. It is concerned with explaining important macro-level facts such as the diffusion of various social practices, patterns of segregation , network structures , typical beliefs, and common ways of acting.
In the classic example of historical materialism, Karl Marx and Friedrich Engels argued that all of human history is the result of conflict between classes, which evolved over time in accordance with changes in society's means of meeting its material needs, i.e. changes in society's mode of production.
Examples include study groups, sports teams, schoolmates, attorney-client, doctor-patient, coworkers, etc. Cooley had made the distinction between primary and secondary groups, by noting that the term for the latter refers to relationships that generally develop later in life, likely with much less influence on one’s identity than primary groups.
If Gaussian elimination applied to a square matrix A produces a row echelon matrix B, let d be the product of the scalars by which the determinant has been multiplied, using the above rules. Then the determinant of A is the quotient by d of the product of the elements of the diagonal of B : det ( A ) = ∏ diag ( B ) d . {\displaystyle \det ...
