While the epidemiologic trends concerning alprazolam (Xanax) are unknown, the use of benzodiazepines, in general, has increased in popularity among youth within recent years. To shed light on the drug problem, the current pilot study used a qualitative approach to investigate relevant beliefs, norms, and perceived addiction associated with alprazolam initiation among 46 youth who were attending an inpatient drug treatment program during the spring of 2004. Overwhelmingly, most participants stated that addiction to alprazolam occurs as early as initial consumption. Most youth in the study stated that their friends felt it was normal to use alprazolam. In addition, their control beliefs revealed that if someone wanted to stop it would be difficult because of the widespread use in their communities and family social reinforcement involved with its use. In this study, a majority of students stated that medical professionals such as doctors and pharmacists were the greatest facilitator of alprazolam acquisition. Implications for these results are discussed. 相似文献

This study reports results from an evaluation of the experimental Rio Hondo driving under the influence (DUI) court of Los Angeles County, California. Interviews and official record checks with 284 research participants who were randomly assigned to a DUI court or a traditional criminal court were assessed at baseline and at 24-month follow-up. The interviews assessed the impact of the DUI court on self-reported drunk driving behavior, the completion of treatment, time spent in jail, alcohol use, and stressful life events. Official record checks assessed the impact of the DUI court on subsequent arrests for driving under the influence and other drinking-related behaviors. Few differences on any outcomes were observed between participants in the experimental DUI court and those assigned to the traditional court. The results suggest that the DUI court model had little additional therapeutic or public safety benefit over the traditional court process. The implication of these findings for the popularity of specialized courts for treating social problems is discussed. 相似文献

Identities, people's subjectively construed understandings of who they were, are and desire to become, are implicated in, and thus key to understanding and explaining, almost everything that happens in and around organizations. The research contribution that this review paper makes is threefold. First, it analyses the often employed but rarely systematically explored concept ‘identity work’, and argues that it is one metaphor among many that may be useful in the analysis of professional and more generally work identities. Second, it focuses on five fundamental, interconnected debates in contemporary identities research centred on notions of choice, stability, coherence, positivity and authenticity. Third, it outlines the roles that the concept ‘identity work’ may play in bridging levels of analysis and disciplinary boundaries, and sketches some possible future identities‐focused ideas for further research. Under‐specification has meant that ‘identity’ has not always fulfilled its analytical promise in either theoretical explorations of identities issues or in empirical studies of identities in practice; and it is to these ends that this paper seeks to contribute. 相似文献

Products based on nanotechnology are rapidly emerging in the marketplace, sometimes with little notice to consumers of their nanotechnology pedigree. This wide variety of nanotechnology products will result (in some cases) in unintentional human exposure to purposely engineered nanoscale materials via the dermal, inhalation, ingestion, and ocular pathways. Occupational, consumer, and environmental exposure to the nanomaterials should be characterized during the entire product lifecycle—manufacture, use, and disposal. Monitoring the fate and transport of engineered nanomaterials is complicated by the lack of detection techniques and the lack of a defined set of standardized metrics to be consistently measured. New exposure metrics may be required for engineered nanomaterials, but progress is possible by building on existing tools. An exposure metric matrix could organize existing data by relating likely exposure pathways (dermal, inhalation, ocular, ingestion) with existing measurements of important characteristics of nanoscale materials (particle number, mass, size distribution, charge). Nanomaterial characteristics not commonly measured, but shown to initiate a biological response during toxicity testing, signal a need for further research, such as the pressing need to develop monitoring devices capable of measuring those aspects of engineered nanomaterials that result in biological responses in humans. Modeling the behavior of nanoparticles may require new types of exposure models that individually track particles through the environment while keeping track of the particle shape, surface area, and other surface characteristics as the nanoparticles are transformed or become reactive. Lifecycle analysis could also be used to develop conceptual models of exposure from engineered nanomaterials. 相似文献

Although fewer people are being diagnosed with AIDS in the U.S. and deaths continue to decline, the number of adults age 50 and older who are living with HIV/AIDS is larger than ever. It is likely that older people will continue to comprise an increasingly larger proportion of individuals diagnosed with HIV/AIDS, reflecting both the ineffective prevention efforts targeting older adults and the highly effective antiretroviral therapies that allow many people to live for significantly longer periods of time. These recent trends have created two distinct populations of older persons with HIV/AIDS: those who were infected later in life and those infected earlier and now aging with HIV disease. Aging with HIV/AIDS presents unique psychosocial challenges that may be exacerbated by the aging process. HIV-related stigma, social support and coping issues and evidence-based psychosocial interventions for older adults with HIV/AIDS are reviewed in this paper and suggestions for future research are discussed. 相似文献

This study tested models of an individual's choice to copy illegally music using survey data from a random sample of adults who acquired recorded music. It added to the short list of studies of crime based on data from a general population sample and formally tested the added predictive power of an augmented crime model containing variables from both the theory of reasoned action (TRA) and rational choice models. The results supported the desirability of using general population samples and the augmented model. Policies that change attitudes and perceived norms have the potential to reduce crime. 相似文献

We explore using an option contract as a price discrimination tool under demand uncertainty. In our capacity game model, a monopolistic supplier has to build capacity before observing the uncertain demand. The demand is generated by two potential customers, who privately know their own types. The types could be either high or low, differing in willingness to pay for each unit of demand. To discriminate between the customer types, the supplier designs option contracts so that only the high type will buy options in advance. The high type will do so because the options can hedge their risk of demand loss when capacity is tight. The supplier profits in three ways. First, the high type customers pay higher marginal prices on average. Second, the high type customers' demand is satisfied as a first priority, guaranteeing allocation efficiency. Third, the supplier can observe the number of options being purchased and so determine customer types, improving capacity investment efficiency. We compare our results to those of classical second degree price discrimination. We show that our proposed framework guarantees the same level of supplier profit even when the supplier cannot discriminate between the customers by bundling products. 相似文献

During the COVID-19 pandemic, families have experienced unprecedented financial and social disruptions. We studied the impact of preexisting psychosocial factors and pandemic-related financial and social disruptions in relation to family well-being among N = 4091 adolescents and parents during early summer 2020, participating in the Adolescent Brain Cognitive DevelopmentSM Study. Poorer family well-being was linked to prepandemic psychosocial and financial adversity and was associated with pandemic-related material hardship and social disruptions to routines. Parental alcohol use increased risk for worsening of family relationships, while a greater endorsement of coping strategies was mainly associated with overall better family well-being. Financial and mental health support may be critical for family well-being during and after a widespread crisis, such as the COVID-19 pandemic. 相似文献
