We examined potential links between cocaine use and street‐based sex work in New South Wales, Australia, following reports of increased cocaine use among injection drug users (IDU). Police data on prostitution and possession/use of cocaine was analysed using time series analysis. Interviews with key informants and IDU were also conducted, and data on cocaine use from ongoing monitoring systems targeted at IDU were analyzed. There was a clear increase in cocaine use among IDU which occurred in 2001. This occurred at the same time as an increase in prostitution offenses. Qualitative data suggested a greater number of primary heroin users were engaging in street‐based sex work, which was driven in part by the increases in cocaine use among this group. Subsequent reductions in cocaine availability led to decreased cocaine use and possession offenses, along with reductions in prostitution offenses.  相似文献

Abstract

Drawing on routine activity theory, this paper examines a sample of college students involved in criminal assault to assess whether victims, offenders, and those who are both victims and offenders show similarities on demographic, social activity, neighborhood, exposure, illegal activities, and alcohol and drug use variables. This research tests previous claims that criminal victims and offenders have numerous shared characteristics and behaviors. For all three groups a wide range of sophisticated measures of lifestyle are used to predict the likelihood of involvement in criminal incidents of assault. Victimization risks are primarily explained by indicators of individuals' exposure to offenders. Likelihood of offending is most usefully explained by demographics and participation in other illegal behaviors. Being both a victim and offender of assault is explained by a more complex set of indicators, encompassing a wide range of factors. Based on these results it appears that, for the crime of assault, victims, offenders, and victim-offenders are three distinct groups, identifiable by varying lifestyle measures. Results provide moderate support for routine activity theory and strongly support the need for refined measures of lifestyle when assessing criminal incident involvement.  相似文献

Despite increasing numbers of children diagnosed with mental health disorders, there is limited research on how children come to understand these diagnoses in childhood. This study examines the retrospective accounts of emerging adults who were diagnosed with mental health disorders in childhood to better understand how they made sense of their diagnoses over time. In-depth, semi-structured interviews were conducted with 42 emerging adults (ages 18 to 22) who were diagnosed with attention deficit hyperactivity disorder (ADHD), depression, generalized anxiety disorder (GAD), and/or bipolar disorder in childhood. Interviews elicited participants' experiences learning about their diagnoses and suggestions for how diagnoses should best be explained to children. Findings demonstrate that participants actively sought and obtained information about their diagnoses over time. They negotiated narratives from several sources, including parents, teachers, mental health professionals, peers, siblings, the media, reading materials, and the Internet. Many of those who embraced medical accounts of their diagnoses did so as they obtained in-depth medical information over time. Meanwhile, those whose parents were open and communicative without using medical narratives suggest it is possible to share information with children without utilizing the terminology of “disorder.” Participants emphasize the importance of being open with children and providing them assurances, explaining that their problems are legitimate, common, and “not their fault.” Implications for social work practice are discussed.  相似文献

This study examines whether changes in impulse control and sensation‐seeking across adolescence and early adulthood reflect independent or interdependent developmental processes. Data are drawn from a national longitudinal study (N = 8,270; 49% female; 33% Black, 22% Hispanic, 45% non‐Black, non‐Hispanic). An autoregressive latent trajectory model is used to test whether development in one trait influences development in the other. Although levels of these traits are inversely correlated, we do not find evidence that change over time in either trait is influenced by the prior level of the other. This failure to reject the null hypothesis is consistent with the view that sensation‐seeking and impulse control are the products of distinct neuropsychological systems that develop independently of one another.  相似文献

The previous decade has seen a drastic shift in the social environment for lesbian, gay, bisexual, transgender, and queer (LGBTQ) people. It is not surprising then to find that the perceived “best” and “worst” aspects of life for nonmetropolitan LGBTQ individuals have also changed. We use data from two cohorts of the Rainbow Illinois survey to examine differences between responses in 2000 and 2011. Furthermore, we examine demographic differences in the perception of what is “best” and “worst” among the 2011 cohort. Results suggest that although the general social climate has improved for some, it remains problematic for others. Implications for social service providers are thoroughly discussed.  相似文献

The purpose of this study was to provide an initial investigation into the work–family conflict (WFC) experiences of individuals who hold a second job. Specifically, we proposed two opposing theoretical arguments regarding the relationship between WFC and four measures of well-being: life satisfaction, physical health, emotional exhaustion, and exercise for individuals who hold two jobs. In a sample of individuals working two jobs, we tested whether the effects of WFC arising from the first job and from the second job exerted an additive or interactive effect on employee well-being. Our results indicated that for emotional exhaustion, physical symptoms, and life satisfaction, the effects of WFC from two jobs are interactive; but that for exercise, the effects of WFC from two jobs are additive. In both cases, the additional WFC experienced as a result of working a second job contributed to the prediction of employee well-being over and above WFC from the first job. Results are discussed within the context of relevant theory, and suggestions are made for future research.  相似文献

This study examined the effect of Testofen, a specialised Trigonella foenum-graecum seed extract on the symptoms of possible androgen deficiency, sexual function and serum androgen concentrations in healthy aging males. This was a double-blind, randomised, placebo-controlled trial involving 120 healthy men aged between 43 and 70 years of age. The active treatment was standardised Trigonella foenum-graecum seed extract at a dose of 600?mg/day for 12 weeks. The primary outcome measure was the change in the Aging Male Symptom questionnaire (AMS), a measure of possible androgen deficiency symptoms; secondary outcome measures were sexual function and serum testosterone. There was a significant decrease in AMS score over time and between the active and placebo groups. Sexual function improved, including number of morning erections and frequency of sexual activity. Both total serum testosterone and free testosterone increased compared to placebo after 12 weeks of active treatment. Trigonella foenum-graecum seed extract is a safe and effective treatment for reducing symptoms of possible androgen deficiency, improves sexual function and increases serum testosterone in healthy middle-aged and older men.  相似文献
