Malthus Fonseca Galvão Ph.D. M.D. José Roberto Pujol‐Luz Ph.D. Cristiane Vieira de Assis Pujol‐Luz Ph.D. Cássio Thyone Almeida de Rosa B.Sc. Luiz Ricardo L. Simone Ph.D. M.D. Sônia Nair Báo Ph.D. Karine Brenda Barros‐Cordeiro M.Sc. Larissa Pessoa M.Sc. Giovanna Bissacot D.M.D. 《Journal of forensic sciences》2015,60(5):1369-1372
Little is known regarding the scavenger fauna associated with buried human corpses, particularly in clandestine burials. We report the presence of 20 shells of the terrestrial snail Allopeas micra, within hollow bones of human remains buried for 5 years, during the process of collecting DNA material. The fact that a large number of shells of A. micra had been found in the corpse and in the crime scene supports the assumption that there was no attempt to remove the corpse from the area where the crime occurred. Despite this, our observations cannot be used to estimate the postmortem interval because there is no precise knowledge about the development of this species. This is the first record of a terrestrial snail associated with a human corpse and its role in this forensic medicine case. 相似文献

The limits of the expert system, TrueAllele® Casework (TA), were explored using challenging mock casework profiles that included 17 single‐source and 18 two‐, 15 three‐ and 7 four‐person DNA mixtures. The sensitivity (ability to detect a minor contributor) of the TA analysis process was examined by challenging the system with mixture DNA samples that exhibited allelic and locus dropout and other stochastic effects. The specificity (ability to exclude nondonors) was rigorously tested by interrogating TA derived genotypes with 100 nondonor profiles. The accuracy with which TA estimated mixture weights of contributors to the two‐person mixtures was examined. Finally, first‐degree relatives of donors were used to assess the ability of the system to exclude close relatives. TA demonstrated great accuracy, sensitivity, and specificity. TA correctly assigned mixture weights and excluded nearly all first‐degree relatives. This study demonstrates the analysis power of the TrueAllele® Casework system. 相似文献

This article describes a Supreme Court of Kentucky court improvement initiative designed to promote uniformity and improved court practice with an ultimate goal of the improvement of outcomes for children and families through implementation of Family Court Rules of Procedure and Practice. Twelve jurisdictions were purposely selected to exhibit a range of family and non‐family court jurisdictions, rural and middle‐sized locations. This article focuses on the results of court case file review related to indicators of due process and timeliness. Implications for court evaluation and reform activities are discussed. 相似文献

Does Level of Intimate Partner Violence and Abuse Predict the Content of Family Mediation Agreements?

This study investigated whether reported levels of intimate partner violence (IPV) and/or abuse (IPV/A) victimization are related to reaching agreement and to the content of mediation agreements of parties seeking to resolve family‐ and child‐related issues. Whether or not parties reached agreement was analyzed for 105 cases at a law school mediation clinic. Agreement content was coded for the 71 cases that reached agreement. Levels of IPV and IPV/A were determined separately for males and females, using a standardized measure. Regression models were utilized to examine reports of IPV or IPV/A as predictors. Results indicated that mediation may help families with a reported history of IPV and IPV/A address a variety of concerns; levels of partner violence/abuse predicted numerous issues in mediation agreements, including arrangements regarding legal custody, parenting time, holidays, child exchanges, interparental communication, safety restrictions, counseling referrals, child support, financial arrangements, and other miscellaneous topics (e.g., relocation). However, some findings were consistent with concerns raised about the use of mediation with parties reporting IPV and IPV/A; for example, increasing levels of male‐perpetrated IPV/A predicted increased likelihood of making an agreement to share legal custody. Further research is needed to resolve the longstanding debate of whether divorce mediation is an effective and safe process for parties demonstrating IPV/A.
- Key Points for the Family Court Community
- This study adds to the debate of whether divorce mediation is an effective and safe process for parties demonstrating IPV/A.
- It examines whether reported levels of IPV and IPV/A victimization are related to reaching agreement and to the content of mediation agreements of parties seeking to resolve family‐ and child‐related issues.
- Results provide some evidence that mediation may help families with a reported history of IPV and IPV/A address a variety of concerns.
- However, some findings are consistent with concerns raised about the use of mediation with parties reporting IPV and IPV/A.
- Findings have implications for the practice of family mediation with parties reporting a history of IPV or IPV/A.

This article examines the recoupling mechanism of campaign‐style enforcement and its effects on environmental regulatory compliance. Drawing on the policy implementation literature and institutional theory, the authors develop a conceptual model of campaign‐style enforcement in which both resource mobilization and power redistribution are theorized to address decoupling problems in regulatory compliance. The two‐pathway recoupling mechanism is evidenced by an empirical investigation of the implementation of China's energy conservation and emission reduction policy as part of that country's 11th Five‐Year Plan. Findings suggest that campaign‐style enforcement can effectively improve regulatory compliance when it addresses the efficiency/legitimacy conflict by providing policy incentives and reorganizing a clear hierarchy of political authority. The article concludes with a discussion of the strengths and limitations of campaign‐style enforcement. 相似文献

Why does the public sector innovate, how should the public sector innovate, and, even more basically, should the public sector innovate? These are some of the questions that these contributions explore and to which they provide some salutary answers. Martin Stewart‐Weeks, an independent consultant working at the intersection of government, innovation, and technology, draws some lessons from his direct experience and advisory work about how the public sector catches the innovation ‘bug’ and turns it into in‐ spired action. From infection to inspiration to implementation, the public sector needs to lower its defences and put itself ‘in harm's way’ to engage with innovators and new ideas. Tim Kastelle, one of Australia's leading innovation scholars and practitioners, sets out some practical ways that the public sector can extend and entrench its innovation practice. These include managing innovation as a process, shifting the risk equation, and experimenting. 相似文献

Within Europe detection rates vary considerably. The differences are too large to be explained purely by the ability of the police to solve cases. In a study covering nine European countries many other factors (external, organisational and technical factors) influencing the detection rate are identified and the influence is empirically made plausible. Next, a comparison is made between the punishment rate and the detection rate. The fact that punishment rates are more stable is explained by the difference between a crime oriented and an offender oriented approach. Also a link is made with the discretionary powers of the police and prosecution. 相似文献
