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).  相似文献

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.  相似文献

Can participatory programs in transitioning countries increase the involvement of citizens beyond the level expected from individual-level characteristics, such as demographic traits, socioeconomic resources, and civic orientations? To answer this question, I examine the causes of participation in the Ugandan constitution-making process. Statistical analysis of a random sample survey of 820 citizens demonstrates that although individual-level factors play a role, many Ugandans participated because mobilizing agents pulled them into the process. I argue that programs to encourage active and equal participation will be most successful if they supplement weak indigenous institutions of mobilization and help all types of citizens to participate early on in the transition to democracy.  相似文献

Sixteen major evaluations of programs to prevent school bullying, conducted in 11 different countries, are reviewed in detail. Of these 16 evaluations, 8 produced desirable results, 2 produced mixed results, 4 produced small or negligible effects, and 2 produced undesirable results. These varying findings may reflect variations in programs, in implementation, in assessment methods, or in evaluation designs. It is concluded that high-quality evaluations are needed in the future, with randomized designs, theoretically grounded interventions, multiple measures of bullying, and attempts to disentangle the effectiveness of different program components.  相似文献

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.  相似文献

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.  相似文献

Recent studies point to the potential theoretical and practical benefits of focusing police resources on crime hot spots. However, many scholars have noted that such approaches risk displacing crime or disorder to other places where programs are not in place. Although much attention has been paid to the idea of displacement, methodological problems associated with measuring it have often been overlooked. We try to fill these gaps in measurement and understanding of displacement and the related phenomenon of diffusion of crime control benefits. Our main focus is on immediate spatial displacement or diffusion of crime to areas near the targeted sites of an intervention. Do focused crime prevention efforts at places simply result in a movement of offenders to areas nearby targeted sites—“do they simply move crime around the corner”? Or, conversely, will a crime prevention effort focusing on specific places lead to improvement in areas nearby—what has come to be termed a diffusion of crime control benefits? Our data are drawn from a controlled study of displacement and diffusion in Jersey City, New Jersey. Two sites with substantial street‐level crime and disorder were targeted and carefully monitored during an experimental period. Two neighboring areas were selected as “catchment areas” from which to assess immediate spatial displacement or diffusion. Intensive police interventions were applied to each target site but not to the catchment areas. More than 6,000 20‐minute social observations were conducted in the target and catchment areas. They were supplemented by interviews and ethnographic field observations. Our findings indicate that, at least for crime markets involving drugs and prostitution, crime does not simply move around the corner. Indeed, this study supports the position that the most likely outcome of such focused crime prevention efforts is a diffusion of crime control benefits to nearby areas.  相似文献
