Assessing the Impact of Leather Industries on Groundwater Quality of Vellore District in South India Using a Geochemical Mixing Model

Abstract

Deterioration of groundwater quality is one of the most critical issues in twenty-first century. The direct relations of water with all the living beings make it an extremely important commodity. Sources of pollution may be of natural or anthropogenic origin. Nowadays anthropogenic sources of pollution are much more than natural sources. India has 1083 tanneries, in which 577 are in Tamil Nadu which accounts for 44% of the total production of India. Vellore district has an indispensable place in the list. Over the 30–40?years groundwater around tanneries has become seriously polluted.     

The Narrative History of the Chocolate Wars: A Short and Tasty Bargaining Game

ABSTRACT

This single lesson classroom game is designed to test student knowledge of Realist and Liberal concepts through an imbalanced resource bargaining mechanic. The game is designed for approximately 20 students divided into state teams of three to four students each and uses chocolate to represent the state teams’ economic capacity, military capability, and human security. Each state team had competing goals, over which they must cooperate or conflict for additional pieces. This game also uses an abstract design to maximize active learning through a short course of play while also making the game useful for testing concepts at any point in an International Relations course. In addition to offering a complete yet easily modifiable game for classroom use, this article also describes the game’s pedagogical contribution to the discipline, game design notes, and techniques for preventing students from stuffing their faces with game pieces.     

Real-time forensic DNA analysis at a crime scene using a portable microchip analyzer

An integrated lab-on-a-chip system has been developed and successfully utilized for real-time forensic short tandem repeat (STR) analysis. The microdevice comprises a 160-nL polymerase chain reaction reactor with an on-chip heater and a temperature sensor for thermal cycling, microvalves for fluidic manipulation, a co-injector for sizing standard injection, and a 7-cm-long separation channel for capillary electrophoretic analysis. A 9-plex autosomal STR typing system consisting of amelogenin and eight combined DNA index system (CODIS) core STR loci has been constructed and optimized for this real-time human identification study. Reproducible STR profiles of control DNA samples are obtained in 2 h and 30 min with ≤0.8 bp allele typing accuracy. The minimal amount of DNA required for a complete DNA profile is 100 copies. To critically evaluate the capabilities of our portable microsystem as well as its compatibility with crime scene investigation processes, real-time STR analyses were carried out at a mock crime scene prepared by the Palm Beach County Sheriff's Office (PBSO). Blood stain sample collection, DNA extraction, and STR analyses on the portable microsystem were conducted in the field, and a successful “mock” CODIS hit was generated on the suspect's sample within 6 h. This demonstration of on-site STR analysis establishes the feasibility of real-time DNA typing to identify the contributor of probative biological evidence at a crime scene and for real-time human identification.     

Counting the costs of HIV and AIDS to civil-society organisations

HIV threatens the survival of many civil-society organisations (CSOs) in Africa. While we know the range of potential costs to such groups, we lack a detailed picture of the extent of the impact. This article highlights important findings from exploratory research in Malawi. Respondents perceived that overall performance in the four CSOs studied declined by an average 20 per cent because they were working in a context of high HIV prevalence. Yet the CSOs' workplace response to this threat was very limited, and they remain highly vulnerable to future impact. We consider why the CSOs have not been more proactive, and we recommend that donor policy should help partners to respond to the epidemic and enable them to remain effective.     

SHOULD JUDGES CLOSE THE GATE ON PAS AND PA?

Parental Alienation Syndrome and Parental Alienation are evolving clinical concepts. They are controversial. Their limits, the limits of the legal system, and recent developments in the use and admissibility of expert evidence call into question the appropriateness of their use within the trial process.     

Campaigning for the Bench: The Corrosive Effects of Campaign Speech?

A new era has emerged in the ways in which candidates for state judicial office campaign. In the past, judicial elections were largely devoid of policy content, with candidates typically touting their judicial experience and other preparation for serving as a judge. Today, in many if not most states, such campaigns are relics of the past. Modern judicial campaigns have adopted many of the practices of candidates for other types of political office, including soliciting campaign contributions, using attack ads, and even making promises about how they will decide issues if elected to the bench. Not surprisingly, this new style of judicial campaigning has caused considerable consternation among observers of the courts, with many fearing that such activity will undermine the very legitimacy of legal institutions. Such fears, however, are grounded in practically no rigorous empirical evidence on the effects of campaign activity on public evaluations of judicial institutions. The purpose of this article is to investigate the effects of campaign activity on the perceived legitimacy of courts. Using survey data drawn from Kentucky, I use both post hoc and experimental methods to assess whether public perceptions of courts are influenced by various sorts of campaign activity. In general, my findings are that different types of campaign activity have quite different consequences. For instance, policy pronouncements by candidates do not undermine judicial legitimacy, whereas policy promises do. Throughout the analysis, I compare perceptions of courts and legislatures, and often find that courts are far less unique than many ordinarily assume. I conclude this article with a discussion of the implications of the findings for the contemporary debate over the use of elections to select judges to the high courts of many of the American states.
