A Study of the Presence of Gunshot Residue in Pittsburgh Police Stations using SEM/EDS and LC‐MS/MS 下载免费PDF全文

Due to possible secondary transfer of gunshot residue (GSR) onto a suspect in police custody prior to sampling, a baseline must be created for the amount of GSR present. With an increase of “lead free” ammunition, testing for both gunpowder and primer GSR is relevant. Seventy samples were collected using carbon‐coated adhesive stubs from four Pittsburgh Police Stations and vehicles to investigate these locations as sources of secondary GSR contamination. These seventy samples were analyzed for primer GSR using scanning electron microscopy‐energy‐dispersive X‐ray spectrometry. One primer GSR particle was detected; no sample was classified as positive for primer GSR. These same samples were then analyzed for gunpowder GSR using liquid chromatography coupled to tandem mass spectrometry to test for akardite II, ethylcentralite, diphenylamine, N‐nitrosodiphenylamine, 2‐nitrodiphenylamine, and 4‐nitrodiphenylamine. Ethylcentralite was quantifiable in two test samples. These results suggest there is a negligible potential for secondary transfer of primer and gunpowder GSR. 相似文献

Research on general strain theory has demonstrated the impact of strain on decisions to engage in crime and delinquency. However, people differ in their responses to strain and only some resort to crime or delinquency. There remain gaps in our knowledge of when, and under what conditions, individuals will react to strain with offending behavior. We rely on interviews with 40 incarcerated men to understand how they cope with specific prison strains, and why they make such coping choices. We find considerable variation in inmates’ coping responses. They use a variety of coping strategies—behavioral, cognitive, and emotional—and only some of these strategies involve offending. Our findings indicate that responses to prison strain are partly a function of past experience with strains, including prior experimentation with coping techniques. Results highlight the unfolding nature of the coping process and expose factors that deserve further attention in tests of GST. 相似文献

Despite a considerable body of research demonstrating the beneficial effects of marriage for criminal desistance, data limitations have resulted in much of this work being based on predominantly white, male samples. In light of the rapidly changing demographic landscape of the US—and particularly the tremendous growth in the Hispanic population—the question of whether the benefits of marriage are generalizable to racial and ethnic minorities is an important one. This research extends prior work on the relationship between marriage and offending by assessing whether the benefits of marriage for criminal offending extend to today’s racial and ethnic minority populations. Using a contemporary sample of 3,560 young adult Hispanic, black and white males followed annually for 13?years spanning the transition to adulthood, we find that while marriage is a potent predictor of desistance for all groups, the benefits of marriage vary substantially across both race and ethnicity. 相似文献

Research indicates that insecurely-attached adolescents are at risk for depression, but little is known about factors that
may influence or explain this vulnerability. The present study focuses on close relationships during adolescence and their
association with depression. Specifically, the objectives were to investigate (1) the role of working models of specific attachment
figures (i.e., mother, father, best friend, and romantic partner) in the prediction of depression; and (2) the existence of
target-specific pathways to depression following relational stress. It was expected that the paths to depression would differ
depending on the attachment figure under consideration. A total of 134 adolescents (n = 88 girls; Mage = 16.95 years; SD = .74) completed attachment questionnaires, a depression inventory, and a computer task consisting of
hypothetical interpersonal vignettes and questions. Insecure attachment relationships with romantic partner, and for girls
only, with mother, were uniquely predictive of depression. Insecurely-attached adolescents' tendency to make negative attributions
in response to stresses fully mediated the attachment–depression association. These adolescents were found to ruminate when
confronted with stresses involving romantic partner, which was also associated with depression. Results underscore the link
between attachment, negative attributions, and depression.

We use a two-wave panel survey of parent-child dyads in the United States to connect online democratic divides with the unequal socialization of political interest in the home. We test a model connecting parent socioeconomic status to the amount of political communication in the home and the subsequent development of youth political interest over the course of an election cycle. We develop the theoretical concept of online civic infrastructure to foreground how interest-driven social media use in adolescence may shape future opportunities for civic and political engagement by building network connections and opening up flows of communication that carry news, political information, and opportunities for mobilization. 相似文献

Research on males shows discrepancies between official records and self-reports of delinquency, thus creating a scaling-up factor. Comparable information for girls is still needed. We investigated discrepancies (scaling up factors) from official records to self-reports in a large sample of girls between ages 12 and 17 (N = 2,450). On average there were three self-reported juvenile female offenders for every individual charged by the police, and for every police charge there were four offenses that were committed. The scaling-up factor was highest in early adolescence, indicating that female offenders at a young age were more likely to stay undetected by the police. The scaling-up factor was significantly lower for African American than white girls: a higher proportion of African American delinquent girls were charged by the police. Racial differences in scaling up were significant only for prevalence, not for frequency of offending. Knowledge about scaling-up factors is important for the design and implementation of intervention programs. We discuss racial differences, implications for justice administration, and practical implications for intervention science. 相似文献

Theory and research suggests that individuals with greater social capital (i.e., resources and benefits gained from relationships, experiences, and social interactions) may be more likely to be active, prosocial bystanders in bullying situations. Therefore, the goal of the current study was to examine the association of social capital (social support and social skills) with prosocial bystander behavior, and the role of internalizing problems as a potential barrier to this relation among 299 students (45.8% girls, 95% White) in sixth, seventh, and eighth grades. Results indicate a positive relation between social capital and prosocial bystander behavior. In addition, internalizing problems were a significant risk factor that may hinder youth—particularly girls—from engaging in defending behavior. Prosocial bystanders are an essential component to prevent and reduce bullying and further research is needed to better understand how to foster prosocial behavior in bullying situations, perhaps by utilizing social capital, related to school bullying. 相似文献

From 2000-2005, Somerville, MA, experienced a number of youth overdoses and suicides. The community response followed CDC recommendations for contagion containment. A community coalition, Somerville Cares About Prevention, became a pivotal convener of community partners and a local research organization, the Institute for Community Health, provided needed expertise in surveillance and analysis. Mayoral leadership provided the impetus for action while community activists connected those at risk with mental health resources. Using a variety of data sources (including death certificates, youth risk surveys, 911 call data, and hospital discharges) overdose and suicide activity were monitored. Rates of suicide and overdose for 10-24-year-olds were higher than in previous years. Using case investigation methods, the majority of suicide victims were found to be linked through common peer groups and substance abuse. Subsequent community action steps included: a community-based trauma response team, improved media relationships, focus groups for suicide survivors, and prevention trainings to community stakeholders. Youth suicide and overdose activity subsided in May of 2005. The community partnerships were critical elements for developing a response to this public health crisis. This collaborative approach to suicide contagion used existing resources and provides important lessons learned for other communities facing similar circumstances. 相似文献

Caffeine is the most widely used psychoactive substance in the world and currently the only one legally available to children and adolescents. The sale and use of caffeinated beverages has increased markedly among adolescents during the last decade. However, research on caffeine use and behaviors among adolescents is scarce. We investigate the relationship between adolescent caffeine use and self-reported violent behaviors and conduct disorders in a population-based cross-sectional sample of 3,747 10th grade students (15–16 years of age, 50.2 % girls) who were enrolled in the Icelandic national education system during February 2012. Through a series of multiple regression models, while controlling for background factors, Attention Deficit Hyperactivity Disorder symptoms and current medication and peer delinquency, and including measures on substance use, our findings show robust additive explanatory power of caffeine for both violent behaviors and conduct disorders. In addition, the association of caffeine to the outcomes is significantly stronger for girls than boys for both violent behaviors and conduct disorders. Future studies are needed to examine to what extent, if at all, these relationships are causal. Indication of causal connections between caffeine consumption and negative outcomes such as those reported here would call into question the acceptability of current policies concerning the availability of caffeine to adolescents and the targeting of adolescence in the marketing of caffeine products. 相似文献

This article examines the responses of the rural poor, both settled peasants and pastoral nomads, to the upheavals unleashed in the Iranian countryside by Riza Shah's adoption of a programme of authoritarian state-building and rapid modernization. The article shows how, contrary to the conventional assumptions of rural passivity held by both Western scholarship and Iranian nationalism, peasant and nomad communities in fact generated a variety of active responses to the regime's initiatives, both on their own account and in combination with other social forces, aimed at defending themselves and resisting unfavourable changes in their relations with landlords and state officials. 相似文献
