The epidemiological impact of an HIV vaccine on the HIV/AIDS epidemic in Southern India
The potential epidemiological impact of preventive HIV vaccines on the HIV epidemic in Southern India is examined using a mathematical deterministic dynamic compartmental model. Various assumptions about the degree of protection offered by such a vaccine, the extent of immunological response of those vaccinated, and the duration of protection afforded are explored. Alternative targeting strategies for HIV vaccination are simulated and compared with the impact of conventional prevention interventions in high-risk groups and the general population. The impact of disinhibition (increased risk behavior due to the presence of a vaccine) is also considered. Vaccines that convey a high degree of protection in a share of or all of those immunized and that convey life-long immunity are the most effective in curbing the HIV epidemic. Vaccines that convey less than complete protection may also have substantial public health impact, but disinhibition can easily undo their effects and they should be used combined with conventional prevention efforts. Conventional interventions that target commercial sex workers and their clients to increase condom use can also be highly effective and can be implemented immediately, before the arrival of vaccines.Poverty and Health,Disease Control&Prevention,Health Monitoring&Evaluation,Public Health Promotion,HIV AIDS,HIV AIDS,Health Monitoring&Evaluation,Adolescent Health,HIV AIDS and Business,Health Service Management and Delivery

ESTIMATION ON GIBBS ENTROPY FOR AN ENSEMBLE
In this world of growing technology, any small improvement in the present scenario would create a revolution. One of the popular revolutions in the computer science field is parallel computing. A single parallel execution is not sufficient to see its non-deterministic features, as same execution with the same data at different time would end up with a different path. In order to see how non deterministic a parallel execution can extend up to, creates the need of the ensemble of executions. This project implements a program to estimate the Gibbs Entropy for an ensemble of parallel executions. The goal is to develop tools for studying the non-deterministic feature of parallel code based on execution entropy and use these developed tools for current and future research
Task irrelevant external cues can influence language selection in voluntary object naming: evidence from Hindi-English bilinguals
We examined if external cues such as other agents’ actions can influence the choice of language
during voluntary and cued object naming in bilinguals in three experiments. Hindi–
English bilinguals first saw a cartoon waving at a color patch. They were then asked to either
name a picture in the language of their choice (voluntary block) or to name in the instructed
language (cued block). The colors waved at by the cartoon were also the colors used as language
cues (Hindi or English). We compared the influence of the cartoon’s choice of color
on naming when speakers had to indicate their choice explicitly before naming (Experiment
1) as opposed to when they named directly on seeing the pictures (Experiment 2 and 3).
Results showed that participants chose the language indicated by the cartoon greater number
of times (Experiment 1 and 3). Speakers also switched significantly to the language
primed by the cartoon greater number of times (Experiment 1 and 2). These results suggest
that choices leading to voluntary action, as in the case of object naming can be influenced
significantly by external non-linguistic cues. Importantly, these symbolic influences can work
even when other agents are merely indicating their choices and are not interlocutors in bilingual
