Many studies have been published regarding suicidal hanging deaths, and most forensic pathologists and coroners are very familiar with such causes of death. Forensic pathologists are challenged over their rulings regarding manner of death in part because the general public has a limited scope of knowledge. One such challenge centers on the question of whether a hanging can be a suicide if the individual is not fully suspended. The authors designed a retrospective study to review suspension in hangings and to analyze other criteria used to help in deciding manner of death. We examined 229 suicidal hanging deaths over an 11-year period (1997 through early 2009) using the data from two separate jurisdictions in Ohio. In conclusion, we found that the vast majority (83.4%) of people who hanged themselves were found partially suspended. Among other criteria analyzed, only the presence of petechial hemorrhages and acute neck injury was statistically significant.  相似文献

Racial disproportionality has been a longstanding issue within child welfare. The continued overrepresentation of black children in the foster care system is troubling. The authors of this article conducted a case study of two counties in New York State that have steadily decreased the number of black children in foster care in an effort to identify what aspects of their child welfare practice impacted the decline. The case study employed document analysis, in-depth interviews, and focus groups with child removal decision makers. Utilizing a grounded theory approach to content organization and analysis, several themes emerged as noticeable factors. Some of the most salient themes included preventive services and resources, community collaborations, case practice development, family meetings, workforce diversity, the court system, and, the most unique, blind removal meetings. The themes found in this study present promising practices to assist in decreasing the racial disparity in child welfare removal decisions.  相似文献

Four individuals died as the result of a propane explosion. As with many propane explosions, the question was raised as to the adequacy of the product's odorization after the autopsy studies had been conducted. In most cases, this question leads to litigation. Ethyl mercaptan is a widely used odorant for propane and was used in this instance. Three of the four victims had blood available at autopsy for study. Quantitative analyses of the victims' blood, obtained during autopsy, were performed using gas chromatography/mass spectrometry, without subjecting the samples to hydrolysis. These analyses determined the relative amounts of propane and ethyl mercaptan in the blood to be 90, 63, and 175 mL/m3 headspace, and 0.36, 0.34, and 0.77 microgram/L blood, respectively. Since mercaptans have been reported in human blood as products of metabolism, modeling studies were conducted to establish the validity of the autopsy data and to develop an autopsy toxicology protocol for investigating explosion deaths. When subjects were not exposed to an atmosphere containing ethyl mercaptan, dimethylsulfide was the only mercaptan detectable in their blood without severe hydrolysis prior to analysis. Metabolic ethyl mercaptan is sufficiently bound to be undetectable by the methods used without hydrolysis. Human subjects were exposed to a flammable mixture of air and propane odorized with ethyl mercaptan. The analyses of the blood from these subjects produced results which were comparable with those for the explosion victims, establishing that the question of odorant adequacy can be addressed at the autopsy of propane explosion victims. It is extremely important that the pathologist and toxicologist investigating gas explosion deaths recognize the valuable evidence existing in the victim's blood.  相似文献

In recent years many scholars have diagnosed a crisis of party politics. This article considers recent changes in the UK and Europe that appear to challenge this idea. Exploring Colin Crouch's notion of ‘post‐democratic’ party politics and considering his diagnosis of shifts in parties' agenda setting, organisation and communication, the article considers evidence of post‐democratic politics and the possibility for future renewal.  相似文献

This study was designed to produce the first baseline measure of the reliability of bloodstain pattern classifications on fabric surfaces. Experienced bloodstain pattern analysts classified bloodstain patterns on pairs of trousers that represented three fabric substrates. Patterns also varied in type (impact, cast‐off, expiration, satellite stains from dripped blood, and transfer) and extent. In addition, case summaries that accompanied each pattern contained contextual cues that either supported the correct answer (i.e., positive bias), were misleading toward an incorrect answer (i.e., negative bias), or contained no directional information (i.e., neutral). Overall, 23% percent of the resulting classifications were erroneous. The majority (51%) of errors resulted from analysts misclassifying satellite stains from dripped blood. Relative to the neutral information, the positive‐bias information increased correct classifications and decreased erroneous classifications, and the negative‐bias information decreased correct classifications and increased erroneous classifications. The implications of these findings for BPA are discussed.  相似文献

The dominant narrative concerning the Bush Doctrine maintains that it is a dangerous innovation, an anomaly that violates the principles of sound policy as articulated by the Founders. According to the conventional wisdom, the Bush Doctrine represents the exploitation of the 9/11 terrorist attacks, by a small group of ideologues—the “neoconservatives”—to gain control of national policy and lead the United States into the war in Iraq, a war that should never have been fought. But far from a being a neoconservative innovation, the Bush Doctrine is, in fact, well within the mainstream of U.S. foreign policy and very much in keeping with the vision of America's founding generation and the practice of the statesmen in the Early Republic. The Bush Doctrine is only the latest manifestation of the fact that U.S. national interest has always been concerned with more than simple security.  相似文献

Providing cash transfers to vulnerable groups reduces vulnerability and chronic poverty; but delivering cash to remote, rural locations can be expensive and insecure. Alternative delivery systems using technology are thus being piloted. This article uses examples from southern Africa to highlight the opportunities and risks involved in using technology to deliver social protection, with particular focus on two schemes in Malawi. It concludes that there is great potential for the use of technology in delivering social protection, especially if employed at a national scale and taking advantage of the full spectrum of uses to ensure cost-efficiency.  相似文献

This study employs the first systematic, empirical analysis that relies on archival data to examine whether the separation of powers influences justices' agenda votes. It spatially models how justices set the Court's agenda under a sincere approach as well as an SOP approach and compares the competing expectations derived therefrom. The results suggest that legislative and executive preferences fail to influence justices' votes. Across every model tested, the data show justices uninfluenced by the separation of powers. These results provide a strong rejoinder to SOP models, since the Court's agenda stage is the most likely stage of the decision‐making process to show signs of an SOP effect.  相似文献

Pakistan has had a chequered democratic history but elections in 2013 marked a second turnover in power, and the first transition in Pakistan's history from one freely elected government to another. How do we best categorize (and therefore understand) political developments in Pakistan? Is it now safe to categorize it as an electoral democracy or is it still a hybrid case of democracy? Using the Pakistani case as an example, this article argues that hybrid regimes deserve consideration as a separate case (rather than as a diminished subtype of democracy or authoritarianism), but must be categorized along a multidimensional continuum to understand the dynamics of power within the political system.  相似文献
