Postmortem computed tomography (PMCT) is integrated into the evaluation of decedents in several American medical examiner offices and medicolegal death investigative centers in many other countries. We retrospectively investigated the value of PMCT in a series of firearm homicide cases from a statewide centralized medical examiner’s office that occurred during 2016. Autopsies were performed or supervised by board-certified forensic pathologists who reviewed the PMCT scans prior to autopsy. PMCT scans were re-evaluated by a forensic radiologist blinded to the autopsy findings and scored by body region (head–neck, thoracoabdominal, and extremities). Injury discrepancies were scored using a modified Goldman classification and analyzed with McNemar’s test. We included 60 males and 20 females (median age 31 years, range 3–73). Based on PMCT, 56 (79.1%) cases had injuries relevant to the cause of death in a single body region (24 head–neck region, 32 thoracoabdominal region). Out of these 56 cases, 9 had a missed major diagnosis by PMCT outside that region, including 6 extremity injuries visible during standard external examination. Yet all had evident lethal firearm injury. We showed that PMCT identifies major firearm injuries in homicide victims and excludes injuries related to the cause of death in other regions when a single body region is injured. Although PMCT has a known limited sensitivity for soft tissue and vascular pathology, it can be combined with external examination to potentially reduce or focus dissections in some of these cases depending on the circumstances and medicolegal needs.  相似文献

Starting in 2016, a number of protests and physical confrontations aimed at individuals and groups associated with right wing politics in the United States have been attributed to an ill-defined entity called “antifa”: short for anti-fascist. A high profile example took place in Charlottseville, Virginia on August 11-12, 2017. During two days of conflict and violence, anti right wing protesters clashed with right wing supporters. During the second day of the confrontation, a right-wing supporter drove a car into a crowd of protesters, killing one person and injuring 35 others. While many antifa supporters see it as a defense against right wing extremism, some on the right view supporters instead as terrorists. I tackle these issues in this essay by applying the guidelines of the Global Terrorism Database (GTD) to determine whether the actions by antifa supporters during the Charlottesville incident consitute terrrorism. I conclude that while the events share many characteristics of terrorist attacks, they do not include all of the elements of terrorism required by the GTD. I also question whether antifa can be considered to constitute a “group” at this point in time. My essay highlights how complicated it is to distinghish terrorism from other forms of illegal violence.  相似文献

Why do some leaders make deeper commitments to human rights treaties (HRAs) by consenting to receive extra monitoring of complaints or communications from individual citizens? Extant theory suggests leaders join HRAs for tangible benefits. However, empirical support for this argument is mixed. To address this mismatch, we approach this question from a different angle. We argue that by ratifying HRAs, leaders send a signal that they are reliable partners who value future returns. Accepting optional articles and protocols that increase monitoring of the state’s human rights behavior, without changing the state’s substantive obligations, helps better signal that the regime does not fear instability nor sees the need to resort to the proscribed abuses in the future. This, in turn, serves as an important middle step to recognizing tangible benefits, such as foreign direct investment, by improving investors’ risk perception of ratified countries.  相似文献

An accruing body of evidence supports associations between self-perceived gender typicality and peer relationship difficulties; however, researchers have yet to evaluate peers' perceptions of problem behaviors to gain insight into the social correlates of gender typicality. A short-term longitudinal study was conducted to evaluate associations between gender atypical problem behavior and subsequent peer relational difficulties for 2,076 fifth graders (M age= 10.27; 53% female). Peer nomination methodology was used to assess participants' classroom peer relationships, problem behaviors, and social-emotional characteristics. Findings showed that youth characterized by gender atypical, compared to gender typical, problem behavior (withdrawn boys/aggressive girls vs. withdrawn girls/aggressive boys, respectively) evidenced higher levels of subsequent peer difficulties; moreover, participation in a mutual friendship was associated with decreased risk for peer relationship maladjustment, particularly among youth characterized by gender atypical problem behavior. Results further revealed that, compared to friendless youth, friended youth earned higher prosocial and peer liking scores and, for withdrawn youth, lower emotional sensitivity scores. The present research contributes to our understanding of the potential short-term consequences of youth's gender atypical problem behavior. Findings underscore the need for supplemental conceptualizations of gender typicality as well as multifaceted interventions designed to promote the acceptance of gender nonnormativity, support the development of adaptive peer relationships, and reduce the occurrence of problem behaviors.  相似文献

Age is one of the most robust correlates of criminal behavior. Yet, explanations for this relationship are varied and conflicting. Developmental theories point to a multitude of sociological, psychological, and biological changes that occur during adolescence and adulthood. One prominent criminological perspective outlined by Gottfredson and Hirschi claims that age has a direct effect on crime, inexplicable from sociological and psychological variables. Despite the attention this claim has received, few direct empirical tests of it have been conducted. We use data from Pathways to Desistance, a longitudinal study of over 1,300 serious youthful offenders (85.8 % male, 40.1 % African-American, 34.3 % Hispanic, 21.0 % White), to test this claim. On average, youths were 16.5 years old at the initial interview and were followed for 7 years. We use multilevel longitudinal models to assess the extent to which the direct effects of age are reduced to statistical and substantive non-significance when constructs from a wide range of developmental and criminological theories are controlled. Unlike previous studies, we are able to control for changes across numerous realms emphasized within differing theoretical perspectives including social control (e.g., employment and marriage), procedural justice (e.g., perceptions of the legitimacy and fairness of the legal system), learning (e.g., gang membership and exposure to antisocial peers), strain (e.g., victimization and relationship breakup), psychosocial maturity (e.g., impulse control, self-regulation and moral disengagement), and rational choice (e.g., costs and rewards of crime). Assessed separately, these perspectives explain anywhere from 3 % (procedural justice) to 49 % (social learning) of the age-crime relationship. Together, changes in these constructs explain 69 % of the drop in crime from ages 15 to 25. We conclude that the relationship between age and crime in adolescence and early adulthood is largely explainable, though not entirely, attributable to multiple co-occurring developmental changes.  相似文献

The following article traces the development of East Germany's secret police, the Stasi, during the reign of Ernst Wollweber, the second Minister of State Security. By examining key Stasi operations during this period, notably the ‘concentrated strikes’ strategy following the June 1953 revolution, the campaign against Ostbüros, and operations to secure the economy, and by examining Wollweber's major speeches, it argues that Wollweber's reign was a decisive one for the Stasi because of the integration of intelligence gathering outside of East Germany (Aufklärung) with domestic surveillance (Abwehr). Although this balance shifted toward external duties in Wollweber's landmark August 1955 speech, Wollweber continued to promote integration of the two duties, in particular by anchoring the intelligence gathering duties in the local-level domestic structures of the Stasi.  相似文献
