Deaths occurring due to rattlesnake envenomization are extremely rare and must be thoroughly investigated in the same manner as any other type of death. Our research presents the case of an adult white male who suffered a fatal timber rattlesnake (Crotalus horridus) envenomation in northwest Florida in 2018. Blood samples were taken from the decedent's heart and vasculature of the chest and sent for serum proteomic analysis. Serum proteomic analysis was utilized in order to identify proteins from timber rattlesnake (C. horridus) found within the victim's blood. The confirmation of the presence of timber rattlesnake venom within the victim's blood allows the forensic pathologist to determine the cause of death most accurately and likewise, assists with the manner of death determination. Blood samples were separated into two groups: one with the abundant endogenous proteins depleted to facilitate detection of lower abundant proteins and one undepleted. In the depleted sample, a total of 712 proteins were identified, with 47 of the proteins (6.6%) occurring originating from timber rattlesnake (C. horridus). Likewise, a total of 742 proteins were identified in the undepleted sample, with 52 of the proteins (7.0%) occurring in timber rattlesnake (C. horridus). No timber rattlesnake (C. horridus) proteins were found in control human serum. 相似文献

Identifying failure mechanisms in skeletal tissue allows a deeper understanding of the effects of specific projectile impacts on bone. While ballistic trauma in flat bones is largely researched, knowledge of how long bones react to gunshot impacts is limited in the literature. The impacts of deforming ammunition appear to produce higher levels of fragmentation; however, these have not been studied in depth. This study compares the damage to femora bone by HP 0.357 and 9 mm projectiles constructed with both full and semi-metal jackets. Impact experiments were undertaken on a single-stage light gas gun involving the use of a high-speed video camera and full reconstruction of the bones to ascertain fracture patterns occurring in the femora. Higher degrees of fragmentation are likened to the presence of semi-jacketed HP projectiles than jacketed HP projectiles. The observations of external facing beveled edges are believed to be associated with the increased separation of the jacket and lead core of projectiles. Additionally, experimentation has shown that the amount of kinetic energy lost postimpact is likely related to the presence or the absence of a metal jacket on an HP projectile. The observed data, therefore, suggest that the composition, rather than the configuration, of a projectile affects the type and extent of the damage. 相似文献

Public management is a domain of research that is now roughly three decades old. Researchers in this area have made important advances in understanding about the performance of public organizations. But questions have been raised about the scope and methods of public management research (PMR). Does it neglect important questions about the development of major institutions of the modern state? Has it focused unduly on problems of the advanced democracies? Has it made itself irrelevant to public debates about the role and design of government, and the capacity of public institutions to deal with emerging challenges? This set of eight short essays were prepared for a roundtable held at the research conference of the PMR Association at the University of Aarhus in June 2016. Contributors were asked to consider the question: Is PMR neglecting the state? 相似文献

In recent years, a range of western jurisdictions has introduced reforms designed to restrict and guide judicial discretion at sentencing. The reforms enacted include mandatory sentencing laws and guiding statutes prescribing sentencing purposes and principles as well as important aggravating and mitigating factors. However, formal guidelines are the most promising and well-studied innovation. We may now add China to the growing list of countries that have recognized the utility of guidelines. Over the past decade, China has slowly developed sentencing guidelines for its courts. The new guidelines contain both general directions with respect to the determination of sentence as well as specific numerical guidelines for common offences. The guidelines do not follow the approach taken by the US schemes, many of which employ a two-dimensional sentencing grid. Instead, China has adopted a strategy consisting of “Starting Point” sentences which are then adjusted by the court to reflect relevant mitigating and aggravating factors. This approach is much closer to the guidelines developed in England and Wales and those proposed but not yet implemented in New Zealand and Israel. In this article, we explore the new Chinese guidelines and provide a limited comparative analysis with guidelines in other jurisdictions. England and Wales is selected as the principal comparator since it has developed and implemented a comprehensive system consisting of both offence-specified guidelines as well as generic guidelines. 相似文献

Anti-immigrant parties in Europe: Ideological or protest vote? 总被引:1,自引:0,他引:1

Abstract. In this article we address the question whether or not the votes for anti–immigrant parties can be considered as protest votes. We define protest votes by the motives underlying electoral choices, building on earlier research done by Tillie (1995) and Van der Eijk & Franklin (1996). That research showed that ideological proximity and party size are the best predictors of party preference. On this basis we designed a typology of motives for party choice and how these motives would manifest themselves empirically. Analyzing the 1994 elections for the European Parliament for seven political systems we show that anti–immigrant parties attract no more protest votes than other parties do, with only one exception: the Dutch Centrumdemocraten. Voting for anti–immigrant parties is largely motivated by ideological and pragmatic considerations, just like voting for other parties. In addition, (negative) attitudes towards immigrants have a stronger effect on preferences for anti–immigrant parties than on preference for other parties. Social cleavages and attitudes towards European unification are of minor importance as determinants of preferences for anti–immigrant parties. The overall conclusion is that a rational choice model of electoral behavior has strong explanatory power for party preferences in general, but also for the support for anti–immigrant parties in particular. 相似文献

Spectator violence has long been associated with professional football in Europe. This article examines the issue of spectator violence from a North American perspective. We begin by noting that there is little systematic research into the scope of spectator disorder in North America. Perhaps for this reason there is little consensus about the true scale of the problem on this side of the Atlantic. It does seem clear at least that there is less spectator violence associated with professional sports in North America. After reviewing a number of explanations for this finding, we conclude that it has less to do with criminal justice policies or practices, than the social context surrounding the 'spectatorship' of sports in North America. Perhaps the most important explanation for the variance in crowd behaviour concerns the demographic profiles of sports spectators in European football and North American sports. 相似文献
