Steroid Use and School Violence,School Violent Victimization,and Suicidal Ideation Among Adolescents
Rebecca L. Elkins Keith King Laura Nabors Rebecca Vidourek 《Journal of school violence》2017,16(4):399-410
School violence, school violent victimization, and suicidal ideation among adolescents are serious public health concerns. This pilot study investigated the influence of steroid use on problem behaviors. Secondary data analyses of the 2014 PRIDE Questionnaire were performed based on information collected from 38,414 high school adolescents. Results indicated high rates of school violence, school violent victimization, and suicidal ideation. Steroid use was directly related to all three problem behaviors. Results varied based on sex, race, grade level, and ethnicity. Health professionals, schools, and prevention specialists may benefit from the findings of this study. Examination of other factors related to steroid use in relation to the aforementioned problem behaviors is imperative. 相似文献

Abstract In 1992, Housing Policy Debate published John Kain's comprehensive review of the extensive scholarly literature on the spatial mismatch hypothesis. This hypothesis maintains that the suburbanization of jobs and involuntary housing market segregation have acted together to create a surplus of workers relative to the number of available jobs in submetropolitan areas where blacks are concentrated. Since Kain's review, more than two dozen new studies on the spatial mismatch hypothesis have been completed. Generally, these studies use more suitable data and superior methodologies than earlier studies and therefore provide the most reliable evidence to date on the spatial mismatch hypothesis. This article critically reviews the new studies and assesses what implications can be drawn for welfare reform. 相似文献

In seeking to understand the variation in asylum grant rates by immigration judges (IJs), we apply a variation of the attitudinal model that we modify by incorporating a cognitive model of decision making, arguing that some pieces of information before IJs are treated objectively while others are treated subjectively. This model allows us to account for informational cues that influence decisions while assessing the impact of national interests and human rights conditions. We find that IJ policy predispositions play a dominant role, and that liberal IJs respond to applicant characteristics differently than conservatives, but also that the law constrains decision making. 相似文献

This article seeks to draw connections between a political ecology of global investment in resource sector development and a culturally informed understanding of rural out-migration across the Lao–Thai border. The author highlights how the departures of rural youth for wage labor in Thailand and the remittances they return to sending villages are becoming important for understanding agrarian transformations in Laos today. In the first section the author introduces the contemporary context of cross-border migrations across the Lao–Thai Mekong border. The second section shifts focus to a village in Laos's central Khammouane Province, where extended field research was conducted between 2006 and 2009. In this village, youth out-migration to Thailand has become a widespread phenomenon, with nearly every household involved. The segmented cultural and gendered features of this migration and its salience for understanding contemporary transformations in this locale invite a broadening of agrarian studies analysis. The final section expands upon how political ecology can provide such a broader analysis by drawing attention to how extractive resource projects affect local tenure rights and livelihoods, with significant rents captured by the state and resource firms. By making these connections, the author argues there are coercive underpinnings to contemporary Mekong migrations, which may be linked to governance problems in the Lao resource sector. 相似文献

Empirical models of spatial voting allow legislators' locations in a policy or ideological space to be inferred from their roll‐call votes. These are typically random utility models where the features of the utility functions other than the ideal points are assumed rather than estimated. In this article, we first consider a model in which legislators' utility functions are allowed to be a mixture of the two most commonly assumed utility functions: the quadratic function and the Gaussian function assumed by NOMINATE. Across many roll‐call data sets, we find that legislators' utility functions are estimated to be very nearly Gaussian. We then relax the usual assumption that each legislator is equally sensitive to policy change and find that extreme legislators are generally more sensitive to policy change than their more centrally located counterparts. This result suggests that extremists are more ideologically rigid while moderates are more likely to consider influences that arise outside liberal‐conservative conflict. 相似文献

A three-stage model isolates conditions under which an executive appointment to a collective choice body, such as a court or a regulatory agency, has an immediate bearing on policy. The model strikes a balance between previous formal models that predict either excessive gridlock or excessive policy responsiveness as a consequence of the politics of appointments. I test the model using approximately four decades of data on U.S. Supreme Court appointments. Two hypotheses summarize the unique predictions of the model and are strongly corroborated. A third, less distinctive hypothesis about strategic judicial retirements is weakly supported . 相似文献

Early students of political tolerance projected a rapid rise in levels of tolerance, but subsequent research has failed to offer conclusive evidence regarding whether tolerance has, in fact, increased. The General Social Survey (GSS) included the same 15 dichotomous tolerance items in the period 1976–1998, seemingly permitting assessment of trends in tolerance through examination of a standard 0–15 scale. Unfortunately, the validity of these data is uncertain because we cannot rule out the possibility that changes in affect toward the five GSS target groups, not true changes in tolerance, drive movement in the longitudinal series. To address this problem, we reexamine the GSS data from the perspective of past discussions of the meaning of tolerance and intolerance. We argue that that the GSS scale captures two aspects of tolerance: whether respondents are tolerant or intolerant; and, among the intolerant, the breadth and depth of their intolerance. We further argue that the first of these dimensions can be measured validly using the GSS data. Our analyses reveal that, at most, tolerance has increased only marginally in the period 1976–1998. 相似文献
