Multiobjective Stochastic Multivariate Stratified Sampling in Presence of Nonresponse

The case of nonresponse in multivariate stratified sampling survey was first introduced by Hansen and Hurwitz in 1946 considering the sampling variances and costs to be deterministic. However, in real life situations sampling variance and cost are often random (stochastic) and have probability distributions. In this article, we have formulated the multivariate stratified sampling in the presence of nonresponse with random sampling variances and costs as a multiobjective stochastic programming problem. Here, the sampling variance and costs are considered random and converted into a deterministic NLPP by using chance constraint and modified E-model. A solution procedure using three different approaches are adopted viz. goal programming, fuzzy programming, and D₁ distance method to obtain the compromise allocation for the formulated problem. An empirical study has also been provided to illustrate the computational details.     

Caste,kinship and the realisation of ‘American Dream’: high-skilled Telugu migrants in the U.S.A.

ABSTRACT

Literature on the Indian diaspora domiciled in the U.S.A. largely portrays the group as educated, highly skilled migrants in pursuit of their American Dream, without critically engaging with the regionally particularised migration trajectories that predispose only certain groups to become skilled migrants from the global South to the North. Migration studies bracket skilled migrants as those who make rational choices and choose formal routes to migrate whereas unskilled migrants often rely on informal channels of kinship or ethnicity to migrate. Unsettling this proposition, in this article, based on an ethnographic study of the high-skilled Telugu professionals in the U.S.A. and their families living in Coastal Andhra, India, I show how aspirational and topographical migration pathways from Coastal Andhra to the U.S.A. are created and sustained through networks of kinship, caste and endogamous transnational marriage alliances. These high-skilled migrants (doctors, engineers and scientists) from the dominant castes have successfully manoeuvred spatial mobility and social upward mobility by utilising ‘caste capital’ within a transnational social field. Moreover, decades of migration from the dominant castes have shaped a caste-inflected transnational habitus among its members who see migration of their youth to the U.S.A. as desirable, and at times, also inevitable.
