The opioid epidemic has affected the United States (US) for decades with fentanyl and its analogs accounting for a recent surge in morbidity and mortality. Currently, there is a relative lack of information characterizing fentanyl-related fatalities specifically in the Southern US. A retrospective study was conducted to examine all postmortem fentanyl-related drug toxicities in Travis County, Texas, encompassing Austin (one of the fastest-growing cities in the US), from 2020 to 2022. Fentanyl contributed to 2.6% and 12.2% of deaths submitted for toxicology between 2020 and 2022, respectively, representing a 375% increase in fentanyl-related deaths over this 3-year period (n = 517). Fentanyl-related fatalities primarily occurred in males in their mid-30s. Fentanyl and norfentanyl concentrations ranged from 0.58 to 320 ng/mL and 0.53 to 140 ng/mL with mean (median) concentrations of 17.2 ± 25.0 (11.0) and 5.6 ± 10.9 (2.9) ng/mL, respectively. Polydrug use was present in 88% of cases, with methamphetamine (or other amphetamines) (25%), benzodiazepines (21%), and cocaine (17%) representing the most frequently identified concurrent substances. Co-positivity rates of various drugs and drug classes widely varied over time. Scene investigations reported illicit powder(s) (n = 141) and/or illicit pill(s) (n = 154) in 48% (n = 247) of fentanyl-related deaths. Illicit oxycodone (44%, n = 67) and illicit “Xanax” (38%, n = 59) pills were frequently reported on scene; however, toxicology only identified oxycodone and alprazolam in 2 and 24 of these cases, respectively. The results of this study provide a better understanding of the fentanyl epidemic in this region creating an opportunity to promote increased awareness, shift focus to harm reduction, and aid in minimizing public health risks.  相似文献

Cartridge cases may contain deposited fingermarks when the firearm was loaded ( http://www.nij.gov/pubs-sum/225320.htm , J Forensic Sci, 53 , 2008 and 812). Cartridge cases can be individualized with microscopic examination. However, heat and friction degrades the deposited fingermark on the fired cartridge cases, if any on the surface. Also, unfired and fired cartridge cases are made of metal, which is a nonporous surface that does not retain fingermarks well ( http://www.nij.gov/pubs-sum/225320.htm ). This study tests the effects of pH level on fingermark clarity on brass fired and unfired cartridge cases and microscopic striation examination (MSE). Two trials were performed to determine the optimal pH in fingermark clarity for both types of cartridges. This was performed through immersion in six pH range solutions from dilutions of sulfuric acid and sodium hydroxide for 24 h for the purpose of enhancing the fingermarks on the metal. The use of the optimal neutral pH level is suggested because immersion of the cartridge cases in pH 1–3 and 3–5 affects MSE.  相似文献

Concerns over rising costs have forced police services to balance increasing fiscal and operational pressures. Discussions of the resources and requirements of police, however, are generally only informed by political expediency and traditional practice. Operational reviews (ORs) can be used to document the demands on police, their capacity to respond, and ways in which they can become more efficient and effective. Drawing on an OR of a major urban Canadian police service, this article provides a broad outline of the components of an OR and the analytics that can be used to answer these key questions.  相似文献

ABSTRACT

This research examines the influence of organizational factors—intrinsic rewards, extrinsic rewards, work relations with management, and work relations with co-workers—on the relationship between public service motivation (PSM) and two work outcomes: job satisfaction and organizational commitment. Using data from the 2005 Australian Survey of Social Attitudes of over 2,200 employees in the Australian public and private sectors, this study found a direct and significant association between the two work outcomes and PSM (and the PSM-fit variable). Despite their significant and direct effects on the work outcomes, the organizational factors did not show any significant moderating effects on the relationships between PSM-fit and the two work outcomes.  相似文献

Public policing in Northern Ireland has gone through a process of reform and governance change in reaction to the peace process and the requirement to shift from a police force, largely engaged in conflict-centred policing, to a policing service dedicated to civil policing and normalisation. During the past decade, Northern Ireland has witnessed a significant decline in recorded sectarian crime. This decline in ethnic conflict has been accompanied by a growth in support for the police, especially within the Catholic community. However, information pertaining to support for public policing is determined at national level and we know little about how residents of sites of previously high levels of political and sectarian conflict feel about policing reform and delivery. In this paper we show that the perception of sectarian crime is much greater than recorded sectarian crime. Moreover, the perception of sectarian crime is a significant predictor of negative attitudes regarding police performance. The paper offers a unique quantitative insight into perceptions of sectarian crime and posits a predicament that is not discussed or debated with regard to the delivery of community policing. The evidence presented offers a benchmark upon which such a debate could occur. We argue that knowledge of sectarian hate crime should not be centred at the national level, but at the more discrete scale of neighbourhood. Perceptions, whether linked to reality, signal or prejudice, can at times destabilise the peace-building process, yet are rarely attended to or discussed. Knowing the difference between recorded and perceived crime as either sectarian exaggeration or actuality would aid localised police-community interaction. Here we provide a statistical basis to stimulate such enquiry.  相似文献
