Violence and substance use disproportionately affect African American youth in urban, disadvantaged communities. Expanding positive peer and adult connections is a mechanism by which organized activity participation may reduce risk of negative outcomes. We assessed if organized activity participation decreases the likelihood of later negative outcomes through expanding positive social connections using a parallel mediation model (Wave 1: N?=?681; 50% female; Mage?=?14.86 years; SD?=?0.65). We found indirect effects from participation to cigarette use (b?=??0.04, 95% CI: ?0.07, ?0.01) and violent behavior (b?=??0.04; 95% CI: ?0.07, ?0.01) through positive peer connections. We did not find indirect effects through positive adult connections. This may be because of the notable influence of peers on negative outcomes during adolescence. Organized activities can help youth expand positive peer connections, which, in turn, reduces risk of later negative outcomes. Implications for prevention are discussed. 相似文献

This article investigates the relationships between outsourcing, bureaucratic personnel quality (BPQ) and citizen satisfaction with public services. Our baseline expectation is of a negative association between outsourcing and service quality; however, we argue that this tendency can be counteracted when the government buyer has a more competent and motivated personnel, not only in managerial positions, but across the board. Better‐educated and paid public employees are likely to have an important moderating effect on service quality through their input into quality specifications, their ability to recognize the provider's consummate or perfunctory behaviour, and their willingness to act on the observed performance. Using data from a cross‐section of Sweden's municipalities, our analysis reveals a robust association between higher levels of outsourcing and lower levels of citizen satisfaction, but the data do not provide unambiguous support for the hypothesis that the strength of this association diminishes when BPQ is higher. 相似文献

Is there a significant relationship between military structure and political liberalization? If so, can military structure and organization be manipulated to influence the process of democratization for the purpose of enhancing inter-state peace? To test the implications of these questions, I will investigate a decidedly contentious premise. Military factors traditionally considered destabilizing in the international environment (to include large, well-trained armed forces organized for offensive or out-of-country operations) have, at critical junctions in the Western experience, had a distinctly positive impact on the emergence and maintenance of the liberal democratic state. If this is indeed the case, and liberal democracy can be shown structurally and normatively to produce inter-state peace, then the preferred policy of peace-desiring states should be to promote and implement military reform at home and abroad that most efficiently generates democratic structures and values, regardless of intuitive fears of international instability. In short, I will argue that if liberal democratic states do not go to war with each other, then the size, proficiency, and strength of their military forces should not be a security dilemma issue. 相似文献

Behavioral and mental health outcomes have been associated with experiencing high levels of stress. Yet, little is known about the link between the nature of stressors, their accumulation over time, and the risk for externalizing and internalizing outcomes. Compared to the general population, African Americans are exposed to a disproportionate number of stressors beginning earlier in life. Incorporating Agnew’s General Strain Theory into the study of stress, this study examined whether different kinds of stressors are equally salient in the risk for violent behaviors and depressive symptoms among African Americans transitioning into young adulthood. It further examined the effects of the accumulation of stressors in different life domains and their effect on risks. This study utilized data from an African American subsample of an ongoing longitudinal study that followed 604 adolescents (53?% females) from 9th grade into adulthood. Multilevel growth curve models were used to examine how changes in stressors across multiple life domains related to violent behaviors and depressive symptoms. We found that continued exposure to perceived daily stress and racial discrimination stress increased the risk for violent behaviors during young adulthood, and exhibited a nonlinear relationship between the accumulation of stressors and risk for violence. Moreover, we found that exposure to perceived daily stress, financial stress, neighborhood stress, and racial discrimination stress increased the risk of depressive symptoms and led to a linear relationship between the accumulation of stressors and risk for depressive symptoms. Findings suggest identifiable stressors that can persist over time to influence risks at young adulthood. 相似文献

Researchers have reported that network characteristics are associated with substance use behavior. Considering that social interactions within online networks are increasingly common, we examined the relationship between online network characteristics and substance use in a sample of emerging adults (ages 18–24) from across the United States (N = 2,153; M = 21 years old; 47 % female; 70 % White). We used regression analyses to examine the relationship between online ego network characteristics (i.e., characteristics of individuals directly related to the focal participant plus the relationships shared among individuals within the online network) and alcohol use and substance use, respectively. Alcohol use was associated with network density (i.e., interconnectedness between individuals in a network), total number of peer ties, and a greater proportion of emotionally close ties. In sex-stratified models, density was related to alcohol use for males but not females. Drug use was associated with an increased number of peer ties, and the increased proportion of network members’ discussion and acceptance of drug use, respectively. We also found that online network density and total numbers of ties were associated with more personal drug use for males but not females. Conversely, we noted that social norms were related to increased drug use and this relationship was stronger for females than males. We discuss the implications of our findings for substance use and online network research. 相似文献

Organized activity participation provides important opportunities for adolescents to develop assets and resources related to positive youth development. Predisposing factors, in addition to sociodemographics and self-selection factors, may influence how youth participate over time. In this study, we used growth mixture modeling with longitudinal data from African American adolescents attending urban high schools in Flint, MI to identify subgroups of participation trajectories (Wave 1 N = 681, mean age at Wave 1 = 14.86 years, 51 % female). We measured activity participation using psychological and behavioral engagement across multiple contexts over the 4 years of high school. We examined how predisposing risk and promotive factors were related to these trajectories, accounting for sociodemographic and self-selection factors. The results indicated three participation trajectories: a low group decreasing over time (74 %), a moderate, consistent participation group (21 %) and a moderate, increasing group (5 %). More substance use was associated with lower odds of being in the moderate/consistent versus low/decreasing participation group. More parental support was associated with lower odds of being in the moderate/increasing versus the moderate/consistent group. Our results suggest that addressing predisposing factors such as substance use may help facilitate participation over time. 相似文献

As Nigeria marked its centennial in 2014, violent sectarianism pried open a historical debate about whether ‘amalgamation’ of the country's two former regions by British authorities in 1914 was a ‘mistake’. Even before independence, however, self-interested nationalism restrained self-interested regionalism, sustaining unification. I argue that a ‘parallel institutionalism’ has ever since mediated the nation's heterogeneity through two different visions of representation. A long pause in state creation, a reduction in the Effective Number of Parties, and declining relevance of a pact that facilitated the 1999 democratic transition have revealed latent tensions in the status of multicultural institutionalism and strengthened liberal institutionalism. I then analyse how demographic, economic, and migratory trends are slowly transforming the structure of representation, placing dilemmas of parallel institutionalism at the centre of future nationhood. Additional research could explore a natural experiment between the northeast, which is facing an Islamic insurgency, and the northwest, which is not. 相似文献

Abstract: This study examined eight previously published ear prediction methods by Welcker, Gerasimov, Fedosyutkin and Nainys, and Broadbent and Mathews. Computed tomography scans of 78 living adults (n1) did not support any of these previously published recommendations. Free earlobes were found to accompany protruding supramastoid crests (Pearson’s χ² < 0.05); and ear length [l] and width [w] differed by sex (p < 0.05), correlated with age (r = 0.38[l]; 0.32[w]), and correlated with facial height (r = 0.37[l]; 0.30[w]). New regression equations (for ear length and width) were generated using these variables in several samples and, where possible, cross‐validated using independent data (n1 = 78, n2 = 2190, n3 = 1328, n4 = 1010, and n5 = 47). As a result of these analyses, four valid and tested methods for ear prediction were identified, but large degrees of error continue to make accurate prediction of the ear, from the skull, problematic. 相似文献
