Youth living in impoverished urban neighborhoods are at risk for becoming hopeless about their future and engaging in violent
behaviors. The current study seeks to examine the longitudinal relationship between social connections, hopelessness trajectories,
and subsequent violent behavior across adolescence. Our sample included 723 (49% female) African American youth living in
impoverished urban neighborhoods who participated in the Mobile Youth Survey from 1998 through 2006. Using general growth
mixture modeling, we found two hopelessness trajectory classes for both boys and girls during middle adolescence: a consistently
low hopelessness class and an increasingly hopeless class with quadratic change. In all classes, youth who reported stronger early adolescent connections to their mothers were less
hopeless at age 13. The probability of later adolescent violence with a weapon was higher for boys and was associated with
the increasingly hopeless class for both boys and girls. Implications for new avenues of research and design of hope-based prevention interventions will
be discussed. 相似文献

In the past two decades, the Journal of Public Affairs has solidified corporate public affairs as a legitimate leadership skillset vital to driving future business growth. Yet, more work at a persistently overlooked gap in the Journal, the intersection of public affairs and family businesses, might shed new light on thriving, trusted, and sustainable business practices. This paper examines the unique contributions of family businesses as trusted influencers. As one of the most prominent forms of business, worldwide, family businesses persistently enjoy unusually high levels of public trust while collectively employing millions of wage earners yet their contributions to corporate external affairs research ostensibly have been largely overlooked. These “silent” community and social influencers offer a potentially new perspective on effective public outreach given their persistent and unique trust advantage. Family business' trust-based capabilities can potentially bring new insights to understanding effective stakeholder engagement, credible communications, and issues management—the sweet spot of corporate public affairs functions. Future research opportunities based on relational- and locational- advantages of trusted family businesses are identified. 相似文献

The career stage theory postulates that employees go through different career stages, and each career stage has different effects on various outcomes, such as job satisfaction. There has been empirical support for the career stage theory from other disciplines, but there has been limited research relating to this theory to corrections. To expand the literature, the current study examined whether different career stages were significant predictors of job satisfactions, while including the personal characteristics and the workplace place variables among Texas correctional officers. The results supported the career state theory: job satisfaction was highest during the entry stage (0–2 years), but was lowest during the second career stage (2–5 years). In career stages three (5–15 years) and four (16+ years), job satisfaction rose. Possible interventions that correctional administrators can undertake to encourage job satisfaction from their staff during the second career stage are discussed. 相似文献

Researchers have found an inverse relationship between immigrant status and violence perpetration. Most studies have examined Mexican immigrants, and few have assessed immigration factors other than nativity. Additionally, the majority have focused on the most serious forms of violence despite the fact that moderate violence is more common. Using data from the 2008 Boston Youth Survey, we generated prevalence estimates of peer violence perpetration across immigration related factors, examined whether risk factors for peer violence differed by these variables, and explored the contribution of risk factors to peer violence perpetration. Recent immigrants had a significantly lower prevalence of peer violence compared to each other generations/time in U.S. group. Known risk factors for violence perpetration varied by generation/time in U.S.: compared to other groups, recent immigrants were less likely to have used substances, and were more likely earn A's and B's in school. Recent immigrants had a significantly lower risk of violence perpetration relative to U.S.-born (RR = 0.35, 95% CI: 0.19, 0.62). Adjusting for known risk factors did not attenuate differences in risk. While immigrant youth had a lower risk of peer violence, the protective effect was diminished among immigrants who had resided in the U.S. for >4 years. This pattern demonstrates that negative assimilation occurs within the first generation, not just across generations. Results suggest that perpetration of violence worsens with increased time in the U.S. Research is needed to identify factors that contribute to the acquisition of behaviors such as violence among recently arrived immigrant youth. 相似文献

Although sexual minority (SM) youth are at an increased risk for being bullied and experiencing depression, it is unclear how caregiver support is interrelated with those variables. Therefore, we sought to assess: (a) the prevalence of nonphysical bullying, depressive symptomatology, and caregiver support among heterosexual and SM girls, (b) the association between caregiver support and bullying in both groups, and (c) whether sexual orientation moderates the interactive effect of caregiver support and bullying on depressive symptoms. Data come from a survey of students in 22 Boston public high schools; 99 of the 832 girls in the analytic sample were SM. We used chi-square statistics to examine group differences, and multiple regression to estimate the association between the caregiver support, sexual orientation, being bullied, and depressive symptomatology. SM girls reported similar levels of caregiver support as heterosexual girls, but reported higher levels of depressive symptomatology. They were also more likely to report nonphysical bullying. Tests for interactions were not statistically significant, suggesting that bullying, caregiver support, and sexual orientation are independently associated with depressive symptomatology. 相似文献

One method that has been touted to help end mass incarceration is using intermediate sanctions. While intermediate sanctions often present as attractive options, there is evidence that as practiced, these sanctions often result in net widening. One of the most common forms of intermediate sanctions are drug courts, which are often viewed as progressive alternatives to locking up people with substance abuse problems. However, along with the dangers of net widening, scholars have shown that many people admitted to drug courts do not seem to have substance abuse problems and could benefit from lesser criminal justice interventions. In the current study, we analyzed intake data from a drug court to determine: (1) what charge(s) drug participants had and (2) how they became involved with the criminal justice system. Among important findings were that a large number of drug court participants were arrested for the possession of one drug only (often marijuana) and that more than half of participants came to the attention of the criminal justice system through a traffic stop rather than through repeated encounters with the criminal justice system. 相似文献

In this study, I use a computerized experiment to test whether elected officials differ from everyday citizens in how they use information to make political choices. Ninety state and local level elected officials took part in the study, as did 179 adults from the general population. I tracked participants’ information use as they attempted to solve two hypothetical public policy problems. The data show that while elected officials differ from everyday citizens in their demographics and in the consistency of their political views, these groups did not differ systematically in their depth of information search, their proclivity to compare choice alternatives, or their depth of information processing. These findings held across two different public policy scenarios, controlling for differences in political knowledge, education, and elective experience. In addition to opening a new methodological frontier for the study of political elites, these results accelerate an ongoing debate between Burkeian paternalists and advocates of a more populist democracy. 相似文献

This study describes the characteristics of modacrylic fibres and includes over 80 samples (previous and current) representing 15 trade names. Fibre morphology was examined using brightfield microscopy. Signs of elongation were determined using polarised light microscopy. Fibre cross sections were also examined. The generic class of fibre was divided into sub groups using polymer composition as determined by FTIR-microscopy. Microscopically, some modacrylic fibres cannot be distinguished from acrylic fibres. Others display unusual optical and morphological features which are a strong indication of their generic class. The infrared spectra provide information about the co-monomer, termonomers added to produced dye sites, the presence of solvent residue, dyes, and additives, e.g. flame retardant material. The infrared spectra should always be recorded before and after any thin layer chromatographic examination of the dye, otherwise peaks attributable to dyes, which may be a valuable comparative feature in casework will be lost. 相似文献
