This paper reports a study on the socio-economic determinants of completed fertility in Mexico. An innovative Poisson Double-Hurdle count model is developed for the analysis. This methodological approach allows low and high order parities to be determined by two different data generating mechanisms, and explicitly accounts for potential endogenous switching between regimes. Unobserved heterogen...

A biased coin is tossed n times independently and sequentially. A “head” switch is a tail followed by a head and a “tail” switch is a head followed by a tail. Joint Laplace transform for the number of “head” switches and “tail” switches are given. For the total number of switches, the central limit theorem and the large deviation principle are established.

Given that the controversy over success and failure of Bt technology still exists, this paper discusses the available field studies that have addressed agro-economic questions of Bt cotton cultivation in India. Since a meta-analysis of studies can give only partial conclusions, owing to differences across study methodologies and coverage, this paper takes a different strategy, i e, looking not ...

In this paper, we present ongoing work on an application-level platform that assists in broadcasting multimedia streams in heterogeneous mobile systems. Our work revolves around the notion of a technology domain, which is a set of resources that serve mobile clients connecting to the mobile system through a specific wireless technology. We consider the policies that technology domains use to (a...

Speakers of certain bilingual communities systematically produce utterances in whichthey switch from one language to another, suggesting that the two language systems syst~matically interact with each other in the production (and reoognitlon) of these sentences. We have investigated this phenomenon in a formal or computational framework which consists of two gramnatical systems and a mechanism ...
