The English Speaking Working Group (ESWG) of the International Society for Forensic Genetics (ISFG) offers an annual Paternity Testing Workshop open to all members of the group. Blood samples, a questionnaire and a paper challenge are sent to the participants. Here, we present the results of the 2002–2008 Paternity Testing Workshops with the objective to evaluate the uniformity of DNA-profiling and conclusions of the participating laboratories as well as to clarify tendencies in typing strategies and biostatistical evaluations of the laboratories. The numbers of participating laboratories increased from 46 in 2002 to 68 in 2008. The results showed an increasing degree of concordance concerning methods and DNA systems used and a high degree of uniformity in typing results with discrepancies in 0.1 and 0.3 % of all submitted PCR-based results. The paper challenges showed uniformity in the calculation of the weight of evidence for simple cases with straight-forward genetic constellations. However, a high degree of variation existed in complex scenarios with rare genetic constellations such as genetic inconsistencies/possible silent alleles, rare alleles and haplotypes. 相似文献

Women and girls constitute a growing proportion of those who are HIV positive or living with AIDS, especially in Africa. Various social, economic and cultural realities make women and girls particularly vulnerable to HIV/AIDS infection. The Society for Women and AIDS in Africa (SWAA) is a pan‐Africanist organisation which works in AIDS prevention through various educational programmes targeted at women. The SWAA uses local networks to get its message across, and realises the importance of involving men in the fight against AIDS in Africa. 相似文献

This article is based on the experiences of the feminist perspectives workshop that met each day of the Congress. It discusses feminism as a worldview and particularly applies that perspective to the Congress proceedings. It examines the Congress in terms of three vital aspects of feminism: power, strategy and diversity. Finally, it suggests some ways in which a global feminist perspective might improve future international conferences. 相似文献

ABSTRACTThe impact agenda in academic research affords rich opportunities – to inform the media, policymakers and the general public; to co-produce research with third sector organisations. In the context of Brexit, the prevailing ignorance of politicians and other stakeholders has been so profound, and the falsehoods that have had popular purchase so baseless, as to make the need for impact and public engagement all the more acute. This is not simply about fact-checking, but about making the case for the very worth of expertise, and reasserting the basic, core scientific values that drive academic work – values that have been trashed by the precepts of a postmodern nihilism, in which all positions are equally (in)valid and only your own gut can be trusted. But challenging these precepts in public arenas has personal and professional costs: significant workload implications, the acquisition of new skills and often a torrent of abuse. As such, this work needs institutional support. Departments need to value it appropriately, to promote equal access to impact opportunities and to confront the discriminatory barriers to (and consequences of) taking up the impact gauntlet. Throughout the Brexit process, expertise and experts have been dismissed and denigrated. The task now is to restore public faith in the value of the pursuit of truth. 相似文献

Although growing attention is being paid to the problem of teen dating violence, to date less is known about perpetrators of victimization. The current article used a subset of 980 adolescents aged 11 to 19 who were surveyed as part of a statewide community service coordinated through Cooperative Extension to survey all youth in target communities about risky health behaviors. The current article examined correlates of perpetration of either physical dating violence or sexual abuse across all levels of the ecological model (individual, family, and community factors). At the bivariate level, individual factors including substance use and low social responsibility, family factors including divorce, low parental monitoring, and low social support, and community variables such as low school attachment and neighborhood monitoring were associated with self-reported perpetration. At the multivariate level, gender and history of victimization were most significant in explaining variance in perpetration. 相似文献

We have developed a robust single nucleotide polymorphism (SNPs) typing assay with co-amplification of 25 DNA-fragments and the detection of 35 human Y chromosome SNPs. The sizes of the PCR products ranged from 79 to 186 base pairs. PCR primers were designed to have a theoretical Tm of 60 +/- 5 degrees C at a salt concentration of 180 mM. The sizes of the primers ranged from 19 to 34 nucleotides. The concentration of amplification primers was adjusted to obtain balanced amounts of PCR products in 8mM MgCl2. For routine purposes, 1 ng of genomic DNA was amplified and the lower limit was approximately 100 pg DNA. The minisequencing reactions were performed simultaneously for all 35 SNPs with fluorescently labelled dideoxynucleotides. The size of the minisequencing primers ranged from 19 to 106 nucleotides. The minisequencing reactions were analysed by capillary electrophoresis and multicolour fluorescence detection. Female DNA did not influence the results of Y chromosome SNP typing when added in concentrations more than 300 times the concentrations of male DNA. The frequencies of the 35 SNPs were determined in 194 male Danes. The gene diversity of the SNPs ranged from 0.01 to 0.5. 相似文献

Over the last years, AI applications have come to play a role in many security‐related fields. In this paper, we show that scholars who want to study AI’s link to power and security should widen their perspective to include conceptual approaches from science and technology studies (STS). This way, scholars can pay attention to critical dynamics, processes, practices, and non‐traditional actors in AI politics and governance. We introduce two STS‐inspired concepts – the micro‐politics of design and development and co‐production – and show how the study of AI and security could benefit from them. In the final section, we turn to the study of AI in the context of Switzerland to underscore what aspects the two previously introduced concepts help to highlight that remain invisible for traditional approaches. 相似文献
