The theory of sensation seeking has conceptualized this construct as a stable personality trait associated with a variety of problem behaviors. Reckless behavior theory posits that increases in reckless behavior during adolescence can be attributed, in part, to increases in sensation seeking. This study evaluated patterns of stability and change in sensation seeking among 868 urban, minority youth (53% female), followed longitudinally across middle school (6th–8th grades). Group-based trajectory analysis identified a stable low group (20%), a moderate increasing group (60%), and a stable high group (20%) each of which demonstrated unique associations with changes in problem behaviors. Stable low sensation seekers reported consistently low levels of aggression, delinquency, and substance use across middle school. Moderate increasing sensation seekers reported significant increases in these risk behaviors over time from levels near zero in the 6th grade. Stable high sensation seekers reported high, stable levels of aggression and delinquency upon entry into middle school as well as significant increases in substance use across middle school. These results lend support to both theories and highlight a need for caution when categorizing adolescents as high or low sensation seekers.  相似文献

Previous research on adolescent girls in relationships with older partners suggests a range of negative outcomes for the adolescent. Using three waves of data from the National Longitudinal Survey of Adolescent Health and a life course perspective, we explore the connection between involvement in age discordant relationships (girls dating males three or more years older) and the course of depressive symptoms among adolescent girls. Our analyses are conducted on the 1,307 girls with data at all three waves who had been in a relationship in the last 18 months. The sample is 55% White, 22% Black, 7% other race and 16% Latina. When comparing early adolescent girls (13–15) and late adolescent girls (16–18), the younger girls are no more likely to have depressive symptoms before entry into the age discordant relationship, yet have greater depressive symptoms shortly after the relationship onset and 5 years later. Older adolescent girls in age discordant relationships, however, have similar levels of depressive symptoms at any time point relative to their peers. These data suggest that a girl’s developmental stage influences whether or not she experiences emotional distress as a result of being in an age discordant relationship.  相似文献

While many adolescents and young adults experiment with substances (e.g., alcohol, cigarette smoking, marijuana), recent research suggests that rural youth and young adults may be more at risk for substance use than their urban counterparts. This study was designed to examine the longitudinal relationships between rural adolescents’ prosocial behaviors and substance use in young adulthood. Furthermore, we examined the potential mediating effects of adolescent substance use, academic investment, and delinquency. Rural youth (N = 531; 263 girls) were surveyed in grades 10–12 (Time 1; M age = 16.17; SD = .91) and again in early adulthood (Time 2). Measures of prosocial behaviors, substance use, academic investment, and deviant activities were assessed at Time 1. At Time 2, measures of marijuana use, cigarette smoking, and getting drunk were administered. Overall, the findings showed that rural adolescents who frequently exhibit prosocial behaviors are less likely to engage in substance use in young adulthood than those who exhibit relatively low levels of prosocial behaviors. These findings indicate that prosocial behaviors may have positive health consequences, establishing behavioral trajectories that lead to lower levels of risky health behaviors in adulthood in rural populations.  相似文献

This article attends to the transformation of national identity that occurs in the context of ‘the multicultural debate’ in the Netherlands, and unfolds on the terrain of Dutch (secular and sexual) exceptionalism. First, it explores the connections between two topics that are prominent in the ‘multicultural debates’ all over Europe and undergird the civilizational discourse of a post-Cold War geopolitical era: discussions about secularism on the one hand, and gender and sexual politics on the other. Through a mode of ‘secular nostalgia’, which mobilizes the understanding of the Netherlands as a place par excellence of emancipation for both women and sexual minorities, the Dutch secular arrangement is restructured in new exclusionary ways. Second, it explores how dominant discourses on the symbolic and material borders of the nation interpellate young Muslim women who often figure as the central ‘subjects of debate’. I rely on the notion of interpellation (Althusser) to explore the question of subject formation, with a particular attention to the epistemological conditions of ‘talking back’ as a subject whose constituency and agency is always already informed by the terms in which she is addressed.  相似文献

Anecdotal evidence points to a significant relationship between repression and rebellion and yet the quantitative civil war literature ignores state strategies, deeming them endogenous or perfectly correlated with polity type. This article seeks to bring the state back in again and examine the causes of states' strategies and the effects of these strategies on non-violent mobilisation. It finds that, under certain circumstances, a state's response to a peaceful opposition movement depends not on its institutions or capacity; rather, it is a function of the state's control of the national security apparatus, autonomy from its constituents, and resources fungible for reform. Additionally, the article concludes that state policy can play a more significant role in explaining the onset of civil conflict than do structural variables such as per capita income, terrain and population size. Historical analysis of coercion and insurgency in the counterfactual case of Honduras illustrates the plausibility of this argument.  相似文献

This paper offers an analysis of the qualitative evidence obtained from a research project in relation to the teaching of a module on the Trials of Dissenters in the context of an undergraduate law degree. It will consider whether a pedagogically innovative course has encouraged and enabled undergraduate law students to think more creatively on the issues raised by specific historic trials and to be prepared to construct more critical and open ended arguments. The study of the Trials of Dissenters, we hoped, would encourage our students to dissent both from the standard model of legal education and from the acceptance of what lecturers say as “true”. We here consider the success of our project in relation to how students view dissent.  相似文献

A review of the available literature and previous research has suggested that there are several factors associated with the deposition of friction ridge skin marks that can affect the quality of the resultant marks, including the quantity of force applied, the angle of friction ridge and surface contact and the duration of friction ridge and surface contact. A device referred to as a fingerprint sampler was designed and constructed to facilitate the deposition of fingermarks for research projects. Fingermarks were deposited with and without the fingerprint sampler and examined for evidence of distortion. The quality of the marks was also assessed. The results of this study suggested that the fingerprint sampler deposited fingermarks without distortion caused by some physical factors associated with deposition and that the marks were of a statistically significantly higher quality than marks deposited without its use.  相似文献

In this serial experiment, five human bones with known post-mortem intervals (PMI) in a soil environment from five different epochs (0.2 to approximately 2000 years) were tested in a blind setup with two established rapid tests for the identification of human blood traces (Hexagon-OBTI test and RSID blood test). Based on previous study results concerning the usability of the Luminol test for the first assessment of the PMI of osseous remains, the question arising was whether those test procedures, which are highly sensitive for the detection of human blood components, could also be used to narrow down the post-mortem interval. Five test series were conducted applying modified standard protocols of the manufactures. The aim was to find out whether with prior reaction steps or a prolonged time of incubation hemoglobin or its metabolites can be dissolved from the bone and positive test results can be achieved dependent on the PMI. Four test series yielded negative results for all bone samples and one test series a uniformly weak positive result. The results indicate that rapid tests based on the detection of blood are not suitable for the determination of the PMI of bone samples despite the modification of the standard protocols. Further thorough research is required to clarify the postmortem degradation of hemoglobin in bones.  相似文献
