Examination of Hacking and Blunt Force Skeletal Trauma

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.     

An Examination of the Relationship Between Media Exposure and Fear of Victimization: Implications of the Superpredator Narrative on Juvenile Justice Policies

The media allow crime to infiltrate the public’s consciousness in every conceivable way, thereby playing a major role in shaping the public’s opinion and attitude toward crime and crime issues (Barak, 1995; Fields & Jerin, 1996; Kappeler & Potter, 2005). Reporters constantly talk about crime, and crime related stories dominate the headlines of local and national newspaper outlets (Dowler, 2003; Pizarro et al, 2007). Some of the most highly rated television programs are based on crime plots and people across social, political, and racial demographics are constantly engaged in crime dialogue generated from local or national news stories. When the focus of these mediums is on youth they become even more profound and contentious. The images portrayed conjure up stereotypes that lead to fear and inflammatory remarks that become entrenched into the national lexicon. The current study uses data from the National Opinion Survey of Crime and Justice to test the relationship between crime-related media viewership and fear of victimization within a nationally representative adult sample. Approximately 42.67% of respondents reported regularly watching crime shows and about the same proportion (42.83%) believed their local media paid too much attention to violent crime. In addition to regular crime-show viewership, confidence in the police, gender, and recent contact with the police were associated with fear of victimization. This article adds to an existing body of research through a largely unexplored area in the administration of justice. It does so within the context of the U.S. juvenile justice system.     

Long-Term Risks and Possible Benefits Associated with Late Adolescent Romantic Relationship Quality

Adolescent romantic relationships have the potential to affect psychological functioning well into adulthood. This study assessed adolescent romantic relationship qualities as long-term predictors of psychological functioning utilizing a longitudinal multi-method, multi-informant study of 80 participants (59% female; 54% Caucasian, 35% African American, 11% mixed or other race) assessed at age 17 along with their romantic partners and at ages 25–27. Controlling for gender, family income, and baseline mental health, partner-reported hostile conflict at age 17 predicted relative increases in internalizing behaviors from age 17 to 27. In contrast, observed teen support with their partner during a help-seeking task at age 17 predicted relative decreases in externalizing behaviors over time. The results are interpreted as suggesting qualities that may help determine whether adolescent romances have positive vs. negative long-term psychological health implications.

Holding on tight – NPM and the New Zealand performance improvement framework

The New Zealand Government's Performance Improvement Framework (PIF) is aimed at public sector organisational improvement. The PIF exemplifies how the characteristics of new public management (NPM) challenge the evolution of performance systems attempting to go beyond performance management. The paper provides an empirical example of the operation of the PIF, using a theoretical frame derived from the literature. The analysis suggests that the PIF design does not yet mitigate the effects of gaming, synecdoche, and reputation-protecting behaviour. The common graded ratings continue to hold the attention of those to whom the PIF is important, acting as a proxy for the whole performance of the organisation. This is a case study of how, despite promising adaptations, performance improvement efforts remain hampered by NPM limitations.     

Physiologic Responses to Racial Rejection Images Among Young Adults from African-American Backgrounds

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.

The Pivotal Role of Adolescent Autonomy in Secondary School Classrooms

Student engagement is an important contributor to school success, yet high school students routinely describe themselves as disengaged. Identifying factors that alter (increase) engagement is a key aspect of improving support for student achievement. This study investigated students’ perceptions of autonomy, teacher connection, and academic competence as predictors of changes in student engagement within the classroom from the start to the end of a course. Participants were 578 (58% female) diverse (67.8% White, 25.2% African American, 5.1% Hispanic, 1.2% Asian American) high school students from 34 classrooms who provided questionnaire data both at the start and the end of a single course. Novel results from a cross-lagged model demonstrated that students who perceived their classrooms as allowing and encouraging their own autonomy in the first few weeks increased their engagement throughout the course, rather than the typical decline in engagement that was demonstrated by students in other classrooms. This finding is unique in that it extended to both students’ perceptions of engagement and observations of student engagement, suggesting a fairly robust pattern. The pertinence of this finding to adolescent developmental needs and its relationship to educational practice is discussed.     

Expanding the Online Political Demos but Maintaining the Status Quo? Internet and Social Media Use by Finnish Voters Prior to Elections, 2003–15

Though reinforcement/mobilisation theories regarding the impact of the Internet on citizens’ political engagement are predictive, there are few longitudinal studies on how the profile of the citizens using the Internet for political purposes has changed and how this relates to such theoretical perspectives. Using survey data from four Finnish parliamentary elections, 2003–15, this longitudinal study examines the evolution of the predictors of belonging to the segment of citizens who extensively engage in searching for political information online during the elections. Additionally, the research longitudinally studies the evolution of the drivers of citizens deeming online sources as important for informing their voting decisions. In light of demographic and resource‐based traits, a mobilisation trend is detected across time in the analyses. As to factors concerning attitudes and orientation to politics, however, a more evident reinforcement trend has emerged. These patterns are also evident when examining social media engagement through searching for political information during campaigns. Although the Internet and social media are becoming important for a demographically increasingly diverse group of citizens, especially the young, it is those already predisposed for doing so who have, over time, engaged politically to an increasing degree through these channels.
