This paper draws on Bourdieusian concepts to examine the social mechanisms driving service ‘choices’ for marginalised young substance users. In doing so, it problematises the individualised understandings of ‘choice-making’ common in the existing literature. The paper uses interview data collected from 26 young substance users to describe the resources they bring to their service encounters, the capitals that they acquire through these interactions, and the ways in which these are mobilised within the fields in which they operate. The analysis finds that services acted as capital-building settings – participants acquired material resources and opportunities for skill-building, and they built relationships that contributed to a positive sense of identity and belonging. But the exchange potentials attached to these capitals were restricted by the logics of service fields that cast them as deficit and limited their opportunities to build productive forms of social capital. By revealing the social mechanisms behind service ‘choices’, the analysis suggests that the most effective services are those that maximise the opportunities for their young clients to build ‘weak ties’, such as with a diverse range of adults who themselves possess resources, and those that acknowledge the identities that young people already possess as rational and self-managing.  相似文献

This study assesses the association of 12th-grade student factors (e.g., grades, classroom misbehaviors) with substance use (i.e., binge drinking, cigarette smoking, marijuana) across large, medium-sized, and nonmetropolitan areas. Based on a sample of 2,189 students from the 2013 Monitoring the Future data set, logistic regression analyses showed that poor student academic and behavioral factors were associated with higher substance use after controlling for gender, race, and socioeconomic status. Interaction analyses further showed no significant differences in the influence of student factors on substance use across locales. Results suggest that prevention efforts against substance use should target student factors regardless of area of residency.  相似文献

Research has found significant benefits in using exercise as an adjunct treatment for substance use. This study used a qualitative grounded theory approach to explore the role of group exercise on maintaining sobriety. Sixteen persons (13 White men and 3 White women, age M = 31.81, SD = 8.23), recruited from a substance use recovery group that meets at a gym in an urban area in the Southeast part of the United States, were individually interviewed. Data were analyzed using Charmaz’s (2006) constructivist grounded theory strategies. Central themes revealed a parallel process between the steps taken to seek sobriety and those taken to maintain sobriety. The driving forces of sobriety success in both was 12 steps and group exercise programming that included elements of mentorship, structure, accountability, and fellowship or community. This study supported the use of physical group exercise as an adjunct treatment option for substance use treatment.  相似文献

While researchers have found that African American youth experience higher levels of juvenile justice involvement at every system level (arrest, sentencing, and incarceration) relative to their other ethnic counterparts, few studies have explored how juvenile justice involvement and number of contacts might be correlated with this broad range of problems. A convenience sample of 638 African American adolescents living in predominantly low-income, urban communities participated in a survey related to juvenile justice involvement. Major findings using logistic regression models indicated that adolescents who reported juvenile justice system involvement versus no involvement were 2.3 times as likely to report mental health problems, substance abuse, and delinquent or youth offending behaviors. Additional findings documented that the higher the number of juvenile justice system contacts, the higher the rates of delinquent behaviors, alcohol and marijuana use, sex while high on drugs, and commercial sex. These findings suggest that identifying and targeting youth who have multiple juvenile justice system contacts, especially those in low-resourced communities for early intervention services, may be beneficial. Future research should examine whether peer network norms might mediate the relationships between juvenile justice involvement and youth problem behaviors.  相似文献

Objective: To investigate sexual orientation differences in college men's motivations for HIV testing. Participants: 665 male college students in the Southeastern United States from 2006 to 2014. Methods: Students completed a survey on HIV risk factors and testing motivations. Logistic regressions were conducted to determine the differences between heterosexual men (HM) and sexual minority men (SMM). Results: SMM were more motivated to get tested by concern over past condomless sex, while HM were more often cited supporting the testing program “on principle” and wanting a free t-shirt. SMM and HM differed in behaviors that impact HIV risk and other demographics. However, differences in testing motivation by concern over past condomless sex or wanting a free t-shirt persisted when controlling for these demographic and behavioral differences. Conclusions: Appropriately designed HIV prevention interventions on college campuses should target SMM's distinct concern over past condomless sex as a testing motivation.  相似文献

This study examines the perceptions of mental illness identity among a group of emerging adults based on their retrospective experiences with diagnoses and psychotropic medication use during their earlier formative adolescent years. A short questionnaire was administered via online social media platforms to volunteers between the ages of 19 and 30 and who self-identified as having taken psychotropic medication between the ages of 12 and 18 (N = 46). Correlation analysis revealed that several variables were associated with a stronger illness identity, including participant’s happiness with their medication experiences, the belief that medication made them more like their “true” selves, and the belief that their diagnosis was accurate. Content analysis of participant narratives suggested themes related to discontinuation and barriers to adherence. These results contribute to the growing knowledge base around lived experiences of psychiatric medication use and suggest further study on how to advance more informed and compassionate mental health care.  相似文献

This article explains Internet users’ self-help activities in protecting their privacy online using structural equation modeling. Based on a representative survey of Swiss Internet users, it reveals past experiences with privacy breaches as a strong predictor of current protective behavior. Further, in line with the ‘privacy paradox’ argument, caring about privacy (privacy attitudes) alone does not necessarily result in substantial self-protection. Most strikingly, however, general Internet skills are key in explaining users’ privacy behavior. These skills enable users to reduce risks of privacy loss while obtaining the benefits from online activities that increasingly depend on the revelation of personal data. Consequently, Internet skills are an essential starting point for public policies regarding users’ self-help in privacy protection.  相似文献

This study, based on a survey of 489 documentary filmmakers, is a case study in copyright policy in and through practice. It assesses the changes in documentary production practice around clearance of copyrighted material since the creation of the Documentary Filmmakers' Statement of Best Practices in fair use in 2005. Fair use, an exotic and occasional feature of documentary film in 2004, has become well known and commonly employed. Creative options for filmmakers concerning the use of third-party material have dramatically improved with changes in norms after the issuing of the Statement. Attitudes about fair use are strongly associated with free expression and creative opportunity, and vary with experience. Where filmmakers have changed work because of copyright concerns, they themselves rather than any gatekeeper have made the decision to do so. Where change is associated with fair use, risk is a common concern. Newer filmmakers are more likely to support the use of copyrighted material to make new work, but less likely to know about fair use, and also more likely to have experienced takedowns online. Both education about and experience with fair use appear to have an effect on practice. Filmmakers continue to lack reliable information on the actual risk landscape, and about fair use on digital platforms.  相似文献

Temporality is fundamental to qualitative longitudinal (QLL) research, inherent in the design of returning to participants over time, often to explore moments of change. Previous research has indicated that talking about the future can be difficult, yet there has been insufficient discussion of methodological developments to address these challenges. This paper presents insights from the Energy Biographies project, which has taken a QLL and multimodal approach to investigating how everyday energy use can be understood in relation to biographical pasts and imagined futures. In particular, we detail innovative techniques developed within the project (e.g. SMS photograph activities) to elicit data on anticipated futures, in ways that engender thinking about participants’ own biographical futures and wider societal changes. We conclude by considering some of the significant benefits and challenges such techniques present. These methodological insights have a wider relevance beyond the substantive topic for those interested in eliciting data about futures in qualitative research.  相似文献
