Hacking trauma is prevalent in forensic cases involving genocide and dismemberment, but research into the identification of this type of trauma is lacking. The present study examines characteristics of hacking and blunt force skeletal trauma in order to determine if there is a point at which blunt force trauma becomes distinguishable from hacking trauma. Ten implements with a range of blade angles (i.e., the striking surface of the implement) were used in conjunction with a controlled-force hacking device to impact 100 limb bones of white-tailed deer (Odocoileus virginianus). Observations of the trauma included the occurrence and degree of fragmentation, the entrance widths of the impacts, and composite scores of six hacking characteristics, especially the distinctive V-shaped kerf. ANOVA tests and regression analyses were used to assess the relationships between these characteristics and the blade angles. A significant relationship (p-value = 0.011) was found between the composite hacking scores and the blade angles, indicating that blunt force and hacking trauma can be distinguished. The entrance widths of the impacts exhibited a significant relationship with the blade angles (p-value = 0.037). There was also a significant relationship between the visibility of a V-shaped kerf in the bones (p-value = 0.003), with visibility decreasing around the 60° blade angle. These data should assist in establishing guidelines to differentiate hacking and blunt force skeletal trauma in cases where the implement is on a spectrum between sharp and blunt. 相似文献

Recent increases in deaths in the United States from synthetic opioids such as fentanyl and fentanyl analogues (fentanyls) have raised concerns about possible occupational exposures to these potent agents. Medicolegal death investigators and autopsy suite staff might perform job tasks involving exposure to fentanyls. The potential for exposure to fentanyls among medicolegal death investigators and autopsy technicians at a state medical examiner's office was evaluated through review of caseload characteristics, injury and illness logs, and procedures and policies and discussions with management and employee representatives. The evaluation showed that this medical examiner's office had low potential for work-related exposure to fentanyls; its standard operating procedures and personal protective equipment requirements should reduce the potential for occupational exposure. Medicolegal death investigation agencies can develop and implement guidance to control exposures and provide workforce education and training to reduce the potential for work-related exposure to fentanyls. 相似文献

Adolescent networks include parents, friends, and romantic partners, but research on the social learning mechanisms related
to delinquency has not typically examined the characteristics of all three domains simultaneously. Analyses draw on data from
the Toledo Adolescent Relationships Study (n = 957), and our analytic sample contains 51% male and 49% female as well as 69% white, 24% African-American, and 7% Latino
respondents. Parents,’ peers,’ and partners’ deviance are each related to respondents’ delinquency, and affiliation with a
greater number of deviant networks is associated with higher self-reported involvement. Analyses that consider enmeshment
type indicate that those with both above average romantic partner and friend delinquency report especially high levels of
self-reported involvement. In all comparisons, adolescents with deviant romantic partners are more delinquent than those youths
with more prosocial partners, regardless of friends’ and parents’ behavior. Findings highlight the importance of capturing
the adolescent’s entire network of affiliations, rather than viewing these in isolation, and suggest the need for additional
research on romantic partner influences on delinquent behavior and other adolescent outcomes.

This study examined (a) the associations between school connectedness and early adolescent adjustment problems over a 1 year
period and (b) the equivalence of these associations across gender. Five hundred middle school students (53.4% female), initially
in the 6th and 7th grades, participated in the two-wave study. Results from two-group cross-lagged panel analyses were consistent
across boys’ and girls’ data. After controlling for baseline levels of adjustment problems, school connectedness predicted
lower levels of early adolescent conduct problems 1 year later. Regarding the opposite direction of associations, and even
after baseline levels of school connectedness were taken into account, conduct problems predicted lower levels of subsequent
school connectedness. There were no cross-lagged associations between depressive symptoms and school connectedness, although
elevated levels of baseline depressive symptoms predicted higher levels of subsequent conduct problems. Findings elaborate
previous research by demonstrating that early adolescents actively shape the middle school environment.

Physiologic reactivity to racially rejecting images was assessed in 35 young adults (10 males, 25 female) from African-American
backgrounds using the startle probe paradigm. In a laboratory setting, participants viewed 16 images depicting racial rejection,
racial acceptance, nonracial negative, and nonracial positive themes. While viewing these images, startling bursts of noise
were presented and the magnitude of the eyeblink responses were measured. Results supported an attentional mechanism which
suggests that, while viewing both racially rejecting and nonracial positive images, individuals may be so absorbed in processing
the images that they appear less distracted by the startling noise. However, these patterns were only found for participants
low in racial regard. Young adults who felt positively about their racial background did not exhibit differential processing
of startle stimuli as a function of slide themes. Race-rejection sensitivity did not moderate startle reactivity. Developmental
implications, particularly in light of coping with racial discrimination, are discussed.

This research analyzes the individual-level factors associated with public support for the private provision of public goods and services. Given that privatization requires the transfer of authority from public to private entities, we argue that beliefs about private companies are an important and overlooked source of heterogeneity in explaining public policy preferences toward privatization. We test this expectation using survey data from the 2014 Cooperative Congressional Election Study. We find that support for privatization is associated with positive beliefs about the motivation of private companies and with favorable views about corporate accountability relative to the accountability of government. Opposition to privatization is associated with beliefs about corporate influence in politics. Preferences for limited government are also associated with support for privatization. These results highlight the potential for beliefs about private companies to serve as a group heuristic in political reasoning and the ability of citizens to make reasoned choices on complex public policy issues. 相似文献
