Status, caste, and market in a changing Indian village

When social and economic conditions change dramatically, status hierarchies in place for hundreds of years can crumble as marketization destabilizes once rigid boundaries. This study examines such changes in symbolic power through an ethnographic study of a village in North India. Marketization and accompanying privatization do not create an independent sphere where only money matters, but due to a mix of new socioeconomic motives, they produce new social obligations, contests, and solidarities. These findings call into question the emphasis in consumer research on top-down class emulation as an essential characteristic of status hierarchies. This study offers insights into sharing as a means of enacting and reshaping symbolic power within a status hierarchy. A new order based on markets and consumption is disrupting the old order based on caste. As the old moral order dissolves, so do the old status hierarchies, obligations, dispositions, and norms of sharing that held the village together for centuries. In the microcosm of these gains and losses, we may see something of the broader social and economic changes taking place throughout India and other industrializing countries.

Exploring omega-3 fatty acids, enzymes and biodiesel producing thraustochytrids from Australian and Indian marine biodiversity

The marine environment harbours a vast diversity of microorganisms, many of which are unique, and have potential to produce commercially useful materials. Therefore, marine biodiversity from Australian and Indian habitat has been explored to produce novel bioactives, and enzymes. Among these, thraustochytrids collected from Indian habitats were shown to be rich in saturated fatty acids (SFAs) and monounsaturated fatty acids (MUFAs), together constituting 51-76 % of total fatty acids (TFA). Indian and Australian thraustochytrids occupy separate positions in the dendrogram, showing significant differences exist in the fatty acid profiles in these two sets of thraustochytrid strains. In general, Australian strains had a higher docosahexaenoic acid (DHA) content than Indian strains with DHA at 17-31 % of TFA. A range of enzyme activities were observed in the strains, with Australian strains showing overall higher levels of enzyme activity, with the exception of one Indian strain (DBTIOC-1). Comparative analysis of the fatty acid profile of 34 strains revealed that Indian thraustochytrids are more suitable for biodiesel production since these strains have higher fatty acids content for biodiesel (FAB, 76 %) production than Australian thraustochytrids, while the Australian strains are more suitable for omega-3 (40 %) production.
