Analytical Challenge in Postmortem Toxicology Applied to a Human Body Found into a Lake after Three Years Immersion 下载免费PDF全文

The body of a 30‐year‐old woman was found in Como lake at a depth of about 120 meters in her own car after 3 years of immersion. The aim of this study was to evaluate psychoactive drugs as well as alcohol biomarkers in biological matrices. The following analyses were initially performed: GC‐MS systematic toxicological analysis on biological fluids and tissues; GC‐MS analysis of drugs of abuse on pubic hair; direct ethanol metabolite determination in pubic hair by LC‐MS/MS. After 7 years, the samples, that had been stored at ?20°C, were re‐analyzed and submitted to an LC‐MS/MS targeted screening method, using multiple reaction monitoring mode. These analyses detected citalopram (150–3000 ng/mL), desmethylcitalopram (50–2300 ng/mL), clotiapine (20–65 ng/mL), and ethyl glucuronide (97 pg/mg). The methods showed an acceptable reproducibility, and the concentrations of citalopram and desmethylcitalopram calculated through the two analytical techniques did not significantly differ in biological fluids. 相似文献

Since sports are increasingly used a way to bring formerly conflicting parties together post-conflict, more work needs to be done to ensure that sports are actually conducted in a way that promotes peace rather than exacerbates the conflict. Since many sports-for-peace programs cross cultural boundaries, this exploratory study was conducted to gain insights into interpersonal and cross-cultural conflicts within sports teams. This research was accomplished with three very culturally diverse teams of college-level athletes in a public university in the United States and focused on the types of conflicts, where those conflicts occurred, how the conflicts developed, who was involved, how the conflicts ended, and their effects on team cohesion. The findings of the study give valuable insight into how cultural differences and their resultant ramifications were viewed and worked through by the athletes involved. The authors also considered some ethical issues that resulted when groups of athletes were brought together from different cultures. This study is a first in a series of studies that examine the types of cross-cultural conflicts that occur within sports teams. The findings in this study are of interest to physical education instructors, coaches, peace education teachers, and professionals using sports to promote peace. 相似文献

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. 相似文献

Economic theories of nonprofit organizations (NPOs) have modified standard economic assumptions to explain altruism and nonprofit entrepreneurship but have neglected their dependence on leadership due to the traditional reluctance of economists to consider phenomena associated with preference change. The relevance of Hermalin's (1998 ) model of leadership by example and Casson's (1991 ) theory of leadership through moral manipulation are considered within an NPO context where leaders seek to influence stakeholder commitments to the organization's quest. The propositions Elster (1998 ) advanced with regard to the relationship between the emotions and decision making are then applied in a theory that explains how NPO leaders can develop a culture of hope that maintains the quality control and product differentiation advantages claimed for these organizations. It is argued that policymakers should consider the dependence of NPOs on the quality of leadership when choosing the organizational mechanism for social service delivery. 相似文献
