The case of a 69‐year‐old man, equipped with an ICD and suffering from several chronic cardiac diseases, who died in a car accident, was presented. We analyzed electrogram records from the ICD explanted from the body during the autopsy, which showed that the driver had suffered from malignant ventricular arrhythmia—ventricular fibrillation (VF). A thorough analysis of the details of the accident, as well as the timing of VF and the rhythm observed after the discharge of the ICD showed that the direct cause of the accident was the episode of arrhythmia resulting in a loss of consciousness. Therefore, the presented case illustrates the usefulness of postmortem analysis of electrogram records from ICDs in the reconstruction of road traffic accidents. In such cases, if the victims are implanted with ICDs, it should be a routine procedure performed by forensic pathologists. 相似文献

Evaluation of cannabinoid concentrations in products from the legal cannabis market has been fraught with uncertainty. The lack of standardized testing methodology and the susceptibility of cannabinoids to degradation under certain storage conditions complicates the efforts to assess total tetrahydrocannabinol (THC) levels across wide geographic areas. There are few peer-reviewed surveys of cannabinoid concentrations in regulated products. Those that have been done have not characterized the effects of differences in analytical methodology, sample population, and storage conditions. Viridis Laboratories, which operates two cannabis safety compliance facilities in Michigan, has analyzed over 34,000 cannabis products throughout 2021 and 2022 before the sale in the regulated market. Fifteen cannabinoids in cannabis flower, concentrates, and infused products were tested using methanolic extraction and analysis by high-performance liquid chromatography with diode-array detection. Methods were validated before use, and the flower analysis procedure was certified by the Association of Analytical Collaboration. All the samples were tested before submission for sale and therefore had not undergone prolonged storage. The results are compared with those seen in other states as well as in the illicit market. Total THC levels in cannabis flower from the regulated market are significantly higher than those seen in illicit products. The distribution of cannabinoid levels is similar in flowers intended for either the medicinal or adult-use markets, with an average potency of 18%–23% of total THC. Total THC in concentrates averages up to 82%. Other cannabinoids are observed at significant levels, mostly in products specifically formulated to contain them. These results may act as a benchmark for potency levels in the regulated market. 相似文献

Angle grinders are one of the most dangerous and frequently used tools in industrial settings. Angle grinder injuries range from superficial cuts to deep penetrating injuries with underlying fracture-dislocation and vascular trauma. The injuries caused by angle grinders mostly involve the head, face, or upper limbs, while the lower limb is an unusual site. The high-speed rotating disc of the angle grinders does not respect anatomical boundaries or structures; therefore, the injuries caused may be disfiguring, permanently incapacitating, or even fatal. We report a fatal case of an angle grinder injury to the lower limb. The victim sustained a sharp cut over the left thigh while woodworking in an industrial setup. The rotating disc of an angle grinder had transected the skin, subcutaneous fat and muscles, and both the femoral vessels of the left side, which led to fatal exsanguination within 10 min of the incident. 相似文献

With domestic violence (DV) at an all-time high, police departments are drastically underutilizing technology to combat DV. Currently, New York police departments complete a “Domestic Incident Report” at the scene of domestic incidents but fail to adequately facilitate support services. New York State should mandate a services component into police DV protocols, specifically by commissioning: (1) an application linked to DV organizations presented at the scene of domestic incidents; and (2) a gateway application to refer victims to the correct services. Such tools would allow for the rendering of more efficient support to DV victims in times of immediate crisis. 相似文献

This article contributes to the conceptualisation of evidence‐based policy through providing a framework of the key factors that influence research utilisation, including those that shape the quality of evidence provided. We apply this framework to an analysis of public policy to regulate the remuneration of freight truck drivers to improve workplace safety in their industry. Recent policymaking concerning the regulation of truck drivers’ remuneration in Australia provides an opportunity to examine the quality and utilisation of research evidence by external evidence providers in opposing political contexts. This article suggests the need for informed and vigilant scrutiny of the contributions of evidence providers to government policymaking, particularly in the case of wicked policy problems about which there are sustained ideological differences that underpin problematisation, research interpretation, and conceivable policy solutions. 相似文献

It has long been argued that shared services represent an efficacious means of securing efficiencies for municipalities. Indeed, pressures from fiscal austerity, taxation limitations, and the specter of forced amalgamations have resulted in an increasing uptake of shared service arrangements. However, the extant evidence is rather inconclusive and is largely restricted to analyzing the nett efficiency outcomes for the specific service shared. We broaden this evidential base by examining the association between shared service production and the efficiency of entire municipalities. Our analysis, employing a 5‐year panel of data, suggests that shared services are associated with a statistically significant reduction in overall municipal efficiency. We conclude by explicating on the public policy implications arising from our prima facie surprising results. 相似文献

提升食品安全治理水平是国家实施食品安全战略的重要内容,准确把握研究的前沿热点和动态趋势,对深化食品安全治理研究有着重要的借鉴和参考意义。以CNKI中国核心期刊数据库所收录的1406篇关于食品安全治理的相关文献为研究对象,运用文献计量法、SATI统计软件和CiteSpace可视化软件展开分析。研究表明,我国食品安全治理研究的发文数量呈现快速增长的趋势;虽已形成一定合作规模的研究团队和研究机构,但核心作者和研究机构分布还比较分散,普遍合作性不强;文献发表的期刊分布较稳定且影响力较大。当前关于食品安全治理的研究热点主要聚焦在农产品质量安全、食品供应链、食品卫生、政府监管和社会共治五个方面,研究趋势朝着治理主体多元化、治理行为主动化以及治理方式智能化方向发展。基于此,对未来食品安全治理研究的重点方向提出了相关建议。 相似文献

This paper examines the evolution of China's food standard‐setting procedures from both domestic and international perspectives, particularly in the context of the internationalization of regulation. After the reform and opening‐up in 1978, state actors and leading enterprises monopolized the process of national food standard setting. With further participation in the global economy in the 21st century, China has become familiar with the international standard‐setting procedures and has modeled its domestic policymaking on these practices. This has resulted in a more transparent, inclusive, scientific, pluralized, and consensus‐based form of decisionmaking. By contrast, the standards of the strategic industries have been harmonized to the standards of international counterparts through a top‐down and authoritarian approach. This paper argues that China uses an accommodative approach, trichotomizing suitable standards and decisionmaking procedures in terms of inclusiveness and transparency, which suits the developmental needs of the domestic market, food export markets, and strategic industries. 相似文献

Among local governments, inter-municipal cooperation is the growing reform; but the literature is silent regarding the determinants of longer-term shared service agreements. We conducted a survey of all local governments in New York State in 2013 to assess the level of sharing across 29 public services. The duration of shared service agreements varies from 1 to 80 years. What explains this difference? Our hierarchical linear model shows that service sharing agreements fall along a cooperation continuum, where cost savings are a determinant of shorter agreements, while the public values of service quality and cross-jurisdictional coordination explain longer-term agreements. We also find that positive past experience with sharing partners increases the duration of sharing agreements. Our analysis lays the foundation for new theories of shared services that build directly from the benefits of improved regional coordination, inter-municipal reciprocity and service quality, not from theories based solely on competition and costs. 相似文献
