Understanding Some Jargons

Jargons are always part of any subject especially if the subject is purely technical or purely subjective like cultural studies. Every new author loves to coin a new word for it to be used by later author referring back to him.
Lets see some of the jargon I've come across so far -

Culture - No idea
Cultural Politics - Still no idea

Cultural Materialism :
Materialism stands for specific like for the "material" like money, physical comforts. This word suffers from negative connotations. Being materialistic is not being divine.
Cultural materialism, takes a similar form. It tries to denote the part of materialism that exists in cultural studies.
Cultural studies are not unbiased as for long they have been driven by corporations who are in turn driven by profit motives. Hence, cultural materialism is using cultural studies for good of materialistic.

May be following excerpts from another website help -

Cultural Materialism is a theoretical paradigm that stresses the empirical study of sociocultural systems within a materialist infrastructure-structure-superstructure framework. The term cultural materialism was coined by Marvin Harris in his foundational text, The Rise of Anthropological Theory (1968). The aim of cultural materialism is best described by Harris who wrote that "[t]he task of cultural materialism is to create a pan-human science of society whose findings can be accepted on logical and evidentiary grounds by the pan-human community"

Non - Reductionism
Reductionism is a belief or system where each concept is believed to be explained by breaking it into simpler concepts. Non-Reductionism would mean then, explaining thing as they are without breaking them up.
Culture is believed to take up non-reductionist approach.

Although doesn't look completely correct to me. Human mind by it very nature thinks in terms of reductions. We understand things by breaking them into simpler pieces.

We understand sentences from words, words from alphabets. It might become quite in evident now due to practice but the process inside our mind is still the same !

Cultural Hegemony
This term refers to domination of one culture by other. Example usually cited is that of colonial system where colonial culture exercises social authority and leadership over subordinate groups through winning or forcing of consent.

However, this seems to be misleading as hegemony is never absolute. There will always be a anti-group, anti-culture prevailing which would affect the overall culture of the system, denying the very act of hegemony.
