Matching dental antemortem (AM) and postmortem (PM) data for human identification is especially challenging when the workforce is limited. Dental hygienists have served mass fatality incidents (MFIs) due to dental-related expertise. However, forensics within dental hygiene education and research on transferable skills is limited. This qualitative balance design study assessed senior dental hygiene students' match accuracy of simulated cases varying in dental identifiers based on AM full mouth series (FMS) radiographs and oral photographs to PM WinID3® odontograms to demonstrate possible disaster victim identification (DVI) transferable skills gained during formal education. A convenience sample of senior dental hygiene students (n = 31) was presented information on WinID3® interpretation, then presented with 5 mismatched cases and asked to visually interpret each to make 10 total matches; five based on AM FMS with simulated PM WinID3® odontograms and five based on AM photographs with PM WinID3® odontograms. Match accuracy scores ranged from 41.9% to 58.1% for cases with 1–10 identifiers, and 77.4% to 93.5% for cases with 11–40 identifiers. Accuracy when matching AM radiographs to PM odontograms versus AM photographs to PM odontograms was compared and revealed no statistical differences in match accuracy depending on image type (p = 0.388 to 1.000). Results of this pilot study suggests transferable match accuracy skills resulted from the participants' dental hygiene formal education. These baseline skills with additional specialized training support the rationale for dental hygienists serving on DVI teams. More research is needed in education and practice when preparing dental hygienists for forensic-based service. 相似文献

Unintended compounds produced by inexperienced clandestine chemists may present a challenge in laboratories tasked with their identification. In March 2020, an anonymously submitted tablet purchased as a generic form of Xanax was analyzed by Erowid's DrugsData.org . The gas chromatography–mass spectrometry (GC–MS) results publicly released online indicated several unidentified compounds due to a lack of database references at that time. Elucidation by our group indicated the presence of several structurally related compounds that were linked to a failed synthesis of alprazolam. For this case study, a published procedure for the synthesis of alprazolam starting with the chloroacetylation of 2-amino-5-chlorobenzophenone was identified as a potential source of this failure. The procedure was reproduced to identify pitfalls of the methodology and examine its possible link to the illicit tablet. Reaction outcomes were analyzed via GC–MS and compared to the tablet submission data. The major compound in this submission, N-(2-benzoyl-4-chlorophenyl)-2-chloroacetamide, along with several related byproducts were successfully reproduced indicating that the tablet contents potentially stem from a failure to synthesize alprazolam. 相似文献

Organic impurity profiling of fentanyl samples associated with recent clandestine laboratory methods

Nearly a decade ago, fentanyl reappeared in the United States illicit drug market. In the years since, overdose deaths have continued to rise as well as the amount of fentanyl seized by law enforcement agencies. Research surrounding fentanyl production has been beneficial to regulatory actions and understanding illicit fentanyl production. In 2017, the Drug Enforcement Administration (DEA) began collecting seized fentanyl samples from throughout the United States to track purity, adulteration trends, and synthetic impurity profiles for intelligence purposes. The appearance of a specific organic impurity, phenethyl-4-anilino-N-phenethylpiperidine (phenethyl-4-ANPP) indicates a shift in fentanyl production from the traditional Siegfried and Janssen routes to the Gupta-patent route. Through a collaboration between the DEA and the US Army's Combat Capabilities Development Command Chemical Biological Center (DEVCOM CBC), the synthesis of fentanyl was investigated via six synthetic routes, and the impurity profiles were compared to those of seized samples. The synthetic impurity phenethyl-4-ANPP was reliably observed in the Gupta-patent route published in 2013, and its structure was confirmed through isolation and structure elucidation. Organic impurity profiling results for illicit fentanyl samples seized in late 2021 have indicated yet another change in processing with the appearance of the impurity ethyl-4-anilino-N-phenethylpiperidine (ethyl-4-ANPP). Through altering reagents traditionally used in the Gupta-patent route, the formation of this impurity was determined to occur through a modification of the route as originally described in the Gupta patent. 相似文献

What Does ‘Collaboration’ Without Government Look Like? The Network Qualities of an Emerging Partnership 下载免费PDF全文

Cross‐sectoral partnerships are increasingly common in Australian human service delivery. Yet research has not often focused on partnerships where private actors broker an arrangement to address complex community needs. Using a combination of interviews, focus groups, and social network analysis (SNA), this paper investigates the network qualities of a nascent partnership between a not for profit (NFP) service provider and a major retail water company that seeks to address financial hardship. Ultimately, we assess whether this represents genuine collaboration or another form of joint action. We find that the privately steered partnership generates instrumental benefits characteristic of cross‐sectoral arrangements, as well as challenges. SNA reveals a very high degree of connection between the partner organisations, but the results suggest that the partnership is coordinative rather than collaborative. We also find that this is leading to tacit organisational and institutional modifications as the NFP assumes a ‘market facing’ posture and adjusts to the demands of working with private sector partners. However, at this early stage of development, the level of systemic adjustment between both organisations remains incomplete. 相似文献

In the last several decades, the field of family violence has paid increasing attention to children’s exposure to partner violence (CEPV). Most of this research has focused on the children of women seeking help for partner violence (PV) victimization. In this paper we examine exposure to PV among children of men who sought help for PV victimization (n?=?408), as compared with children of men in a population-based sample (n?=?666). We examined children’s exposure to psychological, physical, and sexual PV and also examined CEPV that is perpetrated by women, men, or both partners. The results show that CEPV is higher among children of helpseeking men than among children of men from the population-based sample, and that most of that PV is perpetrated by the female partner. We did not find differences in CEPV based in child age or gender. We discuss implications for the field of family violence professionals. 相似文献

The Strategic Use of Evidence (SUE) approach is a framework for planning and executing suspect interviews with the aim of facilitating judgments of truth and deception. US law enforcement officers (N = 59) either received training in the SUE approach or did not. Each officer interviewed a mock suspect (N = 59) who had either committed a simulated security breach or had completed a benign task. The officers who received SUE training interviewed in line with the training: They questioned the suspect systematically, withheld the evidence and critical case information until after questioning, and relied on statement-evidence inconsistency to detect deceit. Consequently, SUE-trained interviewers achieved a higher deception detection accuracy rate (65%) compared to untrained interviewers (43%). 相似文献

Absent from assessments of feminism's influence on the academy and the disciplines is an evaluation of the impact of feminist thought on policy research. The purpose of this paper is to evaluate feminist scholarship's presence in the core policy and higher education journals. The first section of the paper explains why it is important to consider the influence of feminism on the policy literature. This is followed by a discussion of what is meant by feminism in the context of this paper. The third section presents the methodology used in evaluating the literature. The paper concludes with a discussion of the findings and implications 相似文献

The effects of the favorable tax treatment of nonprofit commercial activities are best understood in a framework that explicitly accounts for a number of interactions. These involve differential taxation of nonprofits and for-profits and of nonprofits’ “related” and “unrelated” activities; the preferences of nonprofit executives who may be averse to commercial activity; donors whose giving may be sensitive to nonprofit organization commercial activity; and cost-complementarities between nonprofit core mission-related activities and their secondary money-raising efforts. Differential taxation encourages nonprofits to pursue otherwise avoided commercial ventures by providing excess financial returns that nonprofits can exploit because of their tax-exempt status. Data from the 1992 Statistics of Income (SOI) public use file of Internal Revenue Service (IRS) Form-990 returns indicate that the propensity of nonprofit organizations to undertake both tax-exempt and taxable activities depends on their primary mission-related output and size, the relative importance of government versus private contributions, and the size of the excess return created by differential taxation of nonprofit and for-profit business. Additional analyses of SOI data also show that organizations that engage in taxable commercial activities are likely to allocate joint costs in ways that reduce, and in most cases eliminate, their taxable income. 相似文献
