Current forensic DNA profiling methods rely on the analysis of samples at specialised laboratories with an average turnaround time of several days. The ability to rapidly determine a partial profile of short tandem repeats at the point-of-arrest would be of great benefit to police forces around the world, for example enabling a suspect to be rapidly included or excluded from an investigation. We have developed a homogeneous PCR method for the interrogation of STR loci utilising fluorescent oligonucleotide probes and melting curve analysis. Alleles of the D18S51, TH01 and D8S1179 loci were differentiated and identified on the basis of target length and probe melting temperature. Assay performance was evaluated by comparing melting peak data with the AmpFlSTR® SGM Plus® system. The method is compatible with direct analysis of unpurified buccal swab samples, enabling a partial STR profile to be generated within 1 h. 相似文献

This special issue comprises articles by psychologists, legal scholars, and ethicists on the ethics of expert testimony by experimental psychologists. In it the major ethical questions facing the prospective expert witness are clarified, and alternative positions on these issues are defined and debated. Fundamentals of moral reasoning are discussed, and the realities of interaction with a judicial system that subjects the psychologist to a variety of pressures and limitations are made apparent. The aim is not to offer final answers to complex ethical questions, but rather to provide a framework within which the questions can be considered by the individual psychologist.The conference on ethics of expert testimony by experimental psychologists was supported by National Science Foundation grant No. ISP-8209940. We thank Rachelle Hollander of the Ethics and Values in Science and Technology Program, Joe Young of the Memory and Cognitive Processes Program, and Eric Juengst of the National Endowment for the Humanities for their help in bringing about the conference. 相似文献

In July 2005, the Little Rock, Arkansas, school district implemented a new policy to reorganize its management structure in order to create a more efficient bureaucracy. Using Richard Matland’s ambiguity‐conflict model of policy implementation, the authors examine the implementation of this school reorganization policy. Interviews and surveys were conducted with the superintendent and his executive assistants, school principals, teachers, and staff. In line with Matland’s model, the findings suggest that successful implementation is directly related to the policy characteristics of ambiguity and conflict. However, the authors point to the importance of recognizing particular characteristics for different groups of stakeholders within the policy implementation process. Discrepancies among groups of policy actors in the degree of policy ambiguity and policy conflict lead to strikingly different implementation strategies. 相似文献

Interpersonal violence within lesbian relationships is a significant yet understudied problem. Women attending a gay pride
festival in Atlanta, GA, were asked to complete a survey concerning same-sex interpersonal violence. Women who reported being
in a current or previous same-sex partner relationship were included in the analyses (N = 226). Factors that occurred in the context of interpersonal violence were investigated: substance use, HIV/STI risk behaviors,
barriers to reporting abuse, and attitudes inhibiting seeking of social support. In addition, the survey assessed relationship-related
power dynamics. Results of multivariate analyses support the hypotheses that power imbalance and inequality when making sex-related
decisions within women’s same-sex relationships are associated with interpersonal violence. Further findings suggested that
a combination of factors must be considered when dealing with and reducing the risk for violence in same-sex relationships. 相似文献

This paper explores the connections between education for youth civic engagement and theories and strategies from public health (specifically, epidemiology). We illustrate this with four applications of epidemiologic theory to youth civic engagement: social determinants and fundamental causes, vulnerable populations and cumulative disadvantage, positive spillover, and herd immunity and critical mass. Formalizing concepts of current civics, in schools and the public, as a civic epidemic, we present a case for individual‐ and group‐level interventions based around targeted, school‐based, effective civic education initiatives. Grounded in epidemiological theory, such approaches call attention to the simultaneous need to improve broad civics education and ensure that particular populations receive necessary attentions. 相似文献
