A report of an international collaborative experiment to demonstrate the uniformity obtainable using DNA profiling techniques.

This paper describes a collaborative exercise intended to demonstrate whether uniformity of DNA profile results could be achieved between different European laboratories. It was shown that this goal can be obtained provided that a common protocol is followed (specifically the use of a common electrophoretic buffer as being the most important parameter). Generally, lower molecular weight loci (with lower molecular weight fragments) such as YNH24 perform better than higher molecular weight loci such as MS43a. The results of the exercise are discussed in relation to the objectives of the European DNA profiling group (EDNAP).     

Threatening and otherwise inappropriate letters to members of the United States Congress

The authors examine the characteristics of threatening and otherwise inappropriate communications sent to members of the U.S. Congress by a sample of 86 subjects, 20 of whom threatened assassination. We quote excerpts from these letters and provide quantitative data on such variables as the volume, duration, form, and appearance of such communications; the enclosures; the subjects' perceived relationships to the recipients; the thematic content of the communications; and the messages and threats communicated. Comparisons between 43 subjects who pursued encounters with members of Congress and 43 who did not revealed 17 factors associated with such pursuit. In this population, threateners were significantly less likely to pursue an encounter than inappropriate letter writers who did not threaten, regardless of the type of threat or the harm threatened. Inappropriate letters to members of Congress are compared with those directed to Hollywood celebrities. Mentally disordered persons writing to public figures often mention and sometimes threaten public figures other than those to whom the letters are addressed, which raises important issues regarding notification of endangered third parties and the sharing of information among protective agencies.     

The use of phosphate buffered saline for the recovery of cells and spermatozoa from swabs.

In the forensic science laboratory, the recovery of spermatozoa from vaginal swabs, or vaginal cells from penile swabs, can help determine if sexual intercourse may have taken place. There are several methods used to recover spermatozoa and cells from the swabs before visualisation on a microscope slide and most of these methods use water. Phosphate buffered saline (PBS) is a non-toxic solution used in many biological laboratories. Unlike water, PBS prevents cells rupturing or shrivelling up due to osmosis. This study demonstrates that PBS can be used for the extraction of spermatozoa and cells from swabs and that PBS does not affect subsequent DNA profiling.     

Microbial Sampling and Data Interpretation for Problematic Buildings: Considerations for Construction Related Environmental Claims

Bioaerosol data is often used in cases of building mold infestation alleging damage or adverse health effects upon occupants, despite the lack of consistent sampling and analytical protocols and numerical health-based standards. The most fundamental problem in these scenarios is defining a “significant” difference between a suspect indoor environment and the reference environment, regardless of the type of sampling and analysis utilized. Data interpretation focused upon differences in absolute numerical concentrations of fungi is subject to wide differences in expert opinion. On the other hand, an objective quantification of differences can be expressed in terms of probability and better meets criteria established in evidentiary rules.     

Military Base Closures and the 1996 Congressional Elections

This article examines the extent to which changes in distributional benefits influence congressional election outcomes. Although conventional wisdom holds that a direct link exists between distributional benefits and electoral outcomes (Mayhew 1974b), recent evidence suggests that this link only exists under certain circumstances (Stein and Bickers 1994). In this article, I use 1995 military base closures to test the nature of the relationship. Contrary to recent research on the politics of pork barreling, my findings indicate support for a direct relationship between major base realignments and closures and House electoral outcomes. Specifically, major realignments and closures significantly decreased first‐year Democrats' vote margins in the 1996 House elections.     

Natural Law and the Bhagavad-Gita: The Vedic Concept of Natural Law

Abstract. Western natural law theory emphasises the derivation of principles of right action said to be universal and objective from the application of practical reasonableness to the pursuit of basic human goods that are self‐evident or based on human nature. Critics say its methodology is inherently subjective. In contrast, the Vedic approach to natural law of the Bhagavad‐Gita emphasises the full development of a universal aspect of human nature—consciousness—to promote right action. A healthy person with a developed intellect, clear mind, balanced emotions and full perception is best placed to fulfil his or her society's highest ideals of ethical and lawful conduct. The Vedic approach advocates a supportive social environment and the use of meditation techniques to promote such development. Research has found that the Transcendental Meditation (TM) program promotes improvement in mind, body and behaviour. For example, offenders in Australia, the United States and Senegal practising the technique experienced decreased substance abuse and recidivism and improved wellbeing. From a scientific perspective, TM promotes these improvements by producing a unique psychophysiological state of restful alertness that dissolves stress that blocks the unfoldment of full potential in life.
