Microscopical discrimination of human head hairs sharing a mitochondrial haplogroup

In forensic analyses, determining the level of consensus among examiners for hair comparison conclusions and ancestry identifications is important for assessing the scientific validity of microscopical hair examinations. Here, we present data from an interlaboratory study on the accuracy of microscopical hair comparisons among a subset of experienced hair examiners currently analyzing hair in forensic laboratories across the United States. We examined how well microscopical analysis of hair can reliably be used to differentiate hair samples, many of which were macroscopically similar. Using cut hair samples, many sharing similar macroscopic and microscopic features, collected from individuals who share the same mitochondrial haplogroup as an indication of genetic relatedness, we tested multiple aspects that could impact hair comparisons. This research tested the extent to which morphological features related to ancestry and hair length influence conclusions. Microscopical hair examinations yielded accurate assessments of inclusion/exclusion relative to the reference samples among 85% of the pairwise comparisons. We found shorter hairs had reduced levels of accuracy and hairs from populations examiners were not familiar with may have impacted their ability to resolve features. The reliability of ancestry determinations is not yet clear, but we found indications that the existing categories are only somewhat related to current ethnic and genetic variation. Our results provide support for the continued utility of microscopical comparison of hairs within forensic laboratories and to advocate for a combined analytical approach using both microscopical analysis and mtDNA data on all forensic analyses of hair.     

Forensic Assessment of Adults Reporting Childhood Sexualized Assault: a Lifespan Developmental Analysis

Many adults reporting childhood or adolescent sexualized assault (CSA) seek remedies through civil proceedings, thus necessitating a forensic assessment to determine the nature and extent of any psychological injuries related to such assault. Such assessments pose challenges, as CSA often occurred years earlier and may have affected not only immediate functioning but also later psychological maturation. The present paper explains how a lifespan developmental analysis can assist such assessments. The concepts of psychological development, attachment, developmental trajectory and risk and resilience can help in evaluating whether and how CSA affected normal psychological development, in determining the influence of risk factors other than CSA and in considering resiliency factors. Risk, resilience and psychological function must be examined in the domains of individual abilities and attributes, relationships and significant life activities both pre- and post-assault. Data on pre-assault risk, resilience and function can be used to estimate a “but for the assault” developmental trajectory that can then be compared to the individual’s actual developmental trajectory. This analysis, together with analysis of the severity of CSA, can assist in determining whether and how the CSA that is the basis for civil proceedings contributed to later life psychological injuries.     

SERVICE UTILIZATION AND SATISFACTION WITH SERVICE PROVIDERS IN VICTIMS OF RAPE AND SEXUAL ASSAULT

The aim of the present study was to investigate service utilization and satisfaction with service delivery among victims of rape and sexual assault. The victims completed a questionnaire comprising questions about whether they felt they received the appropriate help following an assault and whether they were met with positive staff attitudes within the public treatment system. The victims completed the questionnaire at three different time points： one month, three months and six months following an assault. Results showed that a high number of victims were satisfied with the support and treatment they received from psychologist and other part of the public help system. However, a high number of victims also reported receiving insufficient help from the social service and the police. Results are discussed in terms of consequences for victim recovery and the importance of receiving feedback from the victims in order to improve public service provision for victims of rape and sexual assault.     

Mitochondrial DNA control region population data from Macedonia

Mitochondrial DNA sequences of the entire control region were analyzed in 200 unrelated individuals from Macedonia. A total of 163 different haplotypes were found as determined by 177 polymorphic sites. The probability of a random match was calculated as 1:121 (0.83%). The basic phylogenetic structure of the Macedonian population as derived from its haplogroup distribution is in agreement with other West-Eurasian populations. Upon publication, the population data are going to be available in the EMPOP database (www.empop.org) [W. Parson, A. Dür, EMPOP—a forensic mtDNA database, FSI:Genetics 1 (2) (2007) 88–92; W. Parson, A. Brandstätter, A. Alonso, N. Brandt, B. Brinkmann, A. Carracedo, et al., The EDNAP mitochondrial DNA population database (EMPOP) collaborative exercises: organisation, results and perspectives, Forensic Sci. Int. 139 (2–3) (2004) 215–226.].     

Co-producing a post-trafficking agenda: collaborating on transforming citizenship in Nepal

This article discusses how a new agenda on post-trafficking is gaining momentum through academic and activist anti-trafficking collaborations focused on co-producing knowledge with women who have returned from trafficking situations. Co-production of this nature is important as the issues raised by post-trafficking scenarios are largely ignored in anti-trafficking strategies, and the stigmatisation and poverty which women in these circumstances encounter means they rarely have a voice in policy-making. Drawing on research in Nepal, we present four types of co-produced data around transforming citizenship post-trafficking, and reflect on the strategies for generating and using them for advocacy purposes.     

Leveraging Administrative Data to Better Serve Children and Families

The challenge of complex social issues drives the need for data systems that can connect information across multiple service delivery systems. Integrated data systems provide significant value for needs assessment, program planning, policy decision making, and collective impact evaluation across a range of social issues. This case study describes a mature county‐based integrated data system. The case study has three aims: (1) to highlight the value of integrated data systems to research, (2) to outline common challenges that such initiatives face, and (3) to present several ongoing considerations for the field that could inform policy recommendations to facilitate the use of integrated data. The authors present examples from the experience of developing this integrated data system, including involvement in the design and evaluation of the first county‐level social impact bond. The case study highlights the benefits and limitations of integrated data use in research and the potential to advance evidence‐based social decision making.     

公共政策可行性研究与政策执行力改进

公共政策质量与政策执行力密切相关,政策本身的不完善是限制执行力提升的重要因素,而加强政策的可行性研究是提高政策质量的有效途径。政策的可行性研究应该包括政治、法律、组织、经济、技术等内容,当然,不可行性分析也是不可缺少的内容。在实际操作中还应警惕可行性分析的异化与具体政策制定环境的不同影响因素。本文以政策的可行性研究为着眼点,从政策质量提高的角度探讨政策执行力提升的路径。
