Youth violence in America has grown to insurmountable levels. Homicide is now the third leading cause of death for youth ages 5–14, the second leading cause of death for those ages 15–24 and the number one cause of death among black males ages 15–34. With increased levels of violence and senseless killings across the nation, there is a need to explore behavioral and environmental causes of high risk behavior and various types of interventions to decrease antisocial behavior. Violence prevention should be approached comprehensively from a myriad of approaches and levels of prevention and intervention that should infiltrate individuals, homes, schools, communities and systems.

Numerous types of theories are being designed, implemented and evaluated to decrease and prevent unhealthy behaviors. While there is a need to continue to refine intervention and containment strategies, a preventative approach to addressing root causes of antisocial behaviors needs to be considered as we comprehensively look at interventions for violence prevention. The purpose of this article is to add to the body of research a theory, the Priority/ Consequence model, which depicts interrelated dynamic behavioral and societal variables that can influence, positively or negatively, attitudes, values and beliefs that establish prioritized behaviors that produce consequences.  相似文献

In 1893, Prime Minister Gladstone introduced the second Irish home rule bill in parliament. The bill broke with tradition in Britain and the empire, as it included provisions from the bill of rights of the United States. Its significance was clear at the time: it was debated for nine days in the committee stage and, with one minor amendment, it remained part of the bill that passed the Commons. However, the bill was defeated in the Lords and, at least in the United Kingdom, bills of rights were dismissed as unnecessary or detrimental to sound governance until well after the second world war. This article therefore tries to understand how this early bill of rights was regarded at the time. Who suggested, or demanded, its inclusion? How did they expect it to be applied? And how did the debate reflect and influence thinking about constitutional law in Britain and the empire?  相似文献

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

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.  相似文献

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.  相似文献

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.  相似文献
