This study investigated the association between risky sexual behavior and drug use among female youth sentenced to a regional juvenile detention center. Preincarceration behavioral health risk data were collected from a modified version of the Youth Risk Behaviors Surveillance Survey completed by respondents. Almost all of the 105 participants had been detained before their current sentence, more than half of them were sexually active before the age of 13, and 70% had smoked marijuana or drank alcohol by age 14. A regression analysis was conducted to determine if preincarceration sexual health risk behaviors were significant enough to predict continued risk behaviors related to pregnancy, disease prevention, and substance use. Findings indicate that youth detention-based prevention programs should emphasize sexual and drug-risk reduction strategies as a means to reduce risky behaviors for this population.  相似文献

ABSTRACT

For decades Hip Hop cultural practices have been disparaged for allegedly inciting and being responsible for the eruption of urban violence. This assumption, likely built upon pre-existing biases regarding the street culture and ethnic minorities where Hip Hop emerged, ignored how some of the genre’s main elements – particularly freestyle rap, breakin’ or breakdancing and graffiti tagging – initially served the purpose of providing at-risk youths with real alternatives to direct physical violence in their day-to-day lives, and continue do so today. It has also ignored broader analogies with other cross-cultural and cross-species manifestations of similar practices that have served for millennia as effective mechanisms for reducing the likelihood of potentially lethal violence. By presenting these manifestations – namely song dueling and mark making – in comparative terms with Hip Hop’s freestyle song and dance battles and tagging territorial contests, this article seeks to highlight the relevance and potential of Hip Hop for preventing violence while also suggesting a common evolutionary backdrop within the context of strategies aimed at minimizing intraspecific aggression.  相似文献

Many adolescents living in contexts characterized by adversity achieve positive outcomes. We adopt a protection–risk conceptual framework to examine resilience (academic achievement, civic participation, and avoidance of risk behaviors) among 1,722 never-married 12–19 year olds living in two Kenyan urban slums. We find stronger associations between explanatory factors and resilience among older (15–19 years) than younger (12–14 years) adolescents. Models for prosocial behavior and models for antisocial behavior emerge as key predictors of resilience. Further accumulation of evidence on risk and protective factors is needed to inform interventions to promote positive outcomes among youth situated in an ecology of adversity.  相似文献

As a best‐selling writer of popular romances during the first half of the twentieth century, Berta Ruck (1878–1978) has been characterised as a producer of ‘omelettes of frivolity and sweetness’ whose appeal was confined to adolescent girls and the servant classes. Closer attention to some of the early novels and to her own evaluation of her work, however, reveals her attempts to confront and articulate the impact of societal change upon a generation whose world was being irrevocably altered by the Great War and its aftermath. Her almost forensic attention to local detail and her treatment of contemporary questions of gender identity make her a compelling chronicler of the period and lend credibility to her claims of a broader readership than that generally associated with the genre.  相似文献

Despite renewed media attention on the wedding, and the emphasis that this pays to bridal performance, feminist analysis of wedding culture has made few inroads. Accounts are needed that understand women's experience of the wedding day, the narrative of becoming the bride, and the way this takes place against a backdrop of postfeminist ambivalence, where traditional wedding practices are re-fashioned through discourses of (consumer) choice and empowerment. In this article, we draw on qualitative data collected with five married women from the Netherlands, who spoke to us about their wedding day and their experience of being/becoming brides. We show how retraditionalisation shapes a new romaticisation of wedding day storytelling, constructed through transformation and the experience of beauty. In analysing these narratives, we show how postfeminist bridal perfection comes to anchor the subjective and affective power of ‘the wedding’ in contemporary culture.  相似文献

DNA is one of the fastest growing tools in forensic sciences, increasing reliability in forensic reports and judgments. The use of DNA has increased in different areas of the forensic sciences, such as investigation of plant species, where plastid DNA has been used to elucidate and generate evidence in cases of traceability of genetically modified and controlled plants. Even with several advances and the practice of using DNA in forensic investigations, there are just few studies related to the identification of genetic tools for the characterization of drug and nondrug-types of Cannabis. Herein, the whole plastomes of two drug-type Cannabis are presented and have their structures compared with other Cannabis plastomes deposited in the GenBank, focusing in the forensic use of plastome sequences. The plastomes of Cannabis sativa “Brazuka” and of the hybrid Cannabis AK Royal Automatic presented general structure that does not differs from the reported for other C. sativa cultivars. A phylogenomic analyses grouped C. sativa “Brazuka” with the nondrug C. sativa cultivars, while the hybrid Cannabis AK Royal Automatic placed isolated, basal to this group. This suggests that the analysis of plastomes is useful toward genetic identification of hybrids in relation to C. sativa.  相似文献
