The present study examined the moderating role of health status (physical, mental, and social health) and the relationships between protective behavioral strategies utilized to reduce high-risk drinking (e.g., avoiding drinking games, setting consumption limits, or having a designated driver) and alcohol use and negative consequences in a sample of heavy drinking college students (N = 1,820). In this high risk sample, multiple regression analyses showed that stronger social health was related to increased drinking, while poorer physical, mental, and social health were related to increased alcohol negative consequences. Further, moderation effects revealed that increasing the use of protective behaviors was associated with significantly less drinking in those with stronger social health, as well as significantly lower numbers of negative consequences among participants with poorer physical and mental health. Implications for college counselors and medical personnel are discussed.  相似文献

Much of the research on adolescent friendships and school achievement has focused on in‐school friends, ignoring the potential effects of having out‐of‐school friendships. The goal of this study was to examine the relation between having relatively more in‐school friends and school achievement among a sample of over 600 12th grade students from ethnically diverse backgrounds. We found that adolescents with more in‐school friends, compared with out‐of‐school friends, had higher grade point averages (GPAs) and that adolescents with higher GPAs had more in‐school friends. These relations were mediated by academic experiences, including those shared with friends. However, as hypothesized, the social aspects of adolescents' friendships did not vary according to their percent of in‐school friends, attesting to the importance of considering both types of friendships in understanding adolescents' social experiences. None of the relations described varied according to gender or ethnicity.  相似文献

The Lam Assessment on Stages of Employment Readiness (LASER) was developed to assess welfare recipients' employment readiness. The LASER consists of 14 items corresponding to Prochaska's stages of change model (Prochaska, DiClemente and Norcross, 1992). A sample of 149 welfare recipients from a work training program participated in the study. The Confirmatory Factor Analysis (CFA) supported the three factors structure corresponding to Prochaska's Pre-Contemplation, Contemplation, and Action stages. A cluster analysis classified the sample into three groups according to their LASER scores. A six months follow-up on employment outcomes showed that those who were in Pre-contemplation stage had the poorest employment outcome (25%), those who were in the Action stage had the best outcome (56%) and those in the Contemplation stage were in between (38%). Implications for work rehabilitation and treatment matching were discussed.  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 present sufficient conditions for monotone matching in environments where utility is not fully transferable between partners. These conditions involve not only complementarity in types of the total payoff to a match, as in the transferable utility case, but also monotonicity in type of the degree of transferability between partners. We apply our conditions to study some models of risk sharing and incentive problems, deriving new results for predicted matching patterns in those contexts.  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

The benefits of livelihoods thinking and approaches are widely recognised. This article focuses on an important gap in much of the conceptualization and application of ‘livelihood approaches’— a lack of emphasis on markets and their roles in livelihood development and poverty reduction. The omission is important, as it can lead to failure to identify and act on a wider range of market, institutional and technological opportunities and constraints. An alternative conceptualisation is proposed, with markets as one particular set of institutional mechanisms for co‐ordination and exchange in an economy. It is argued that more explicit attention to interactions between institutions, technology and assets in livelihood analysis may be valuable in conceptualising and managing programmes for livelihood development and poverty reduction.  相似文献

This essay pays tribute to Lawrence Grossberg and his influence through a consideration of radical contextualism – an analytical process that: (1) understands reality as contingently relational, complex, and always open to alteration; and (2) attempts to narratively represent the messiness and complexity of empirical reality as rigorously as possible (with an explicit recognition of the limits of our ability to do so). The piece opens by reflecting briefly on these principles with respect to the genre of intellectual tribute – that is, to contextualize what it means to talk about Larry and his work within the framework of the advisor/advisee relationship. How do you combine the care of engagement with the ethics of argumentation to make a statement that is as personal as it is intellectual? From there, I situate radical contextualism within Cultural Studies as both an ethical-intellectual commitment and an analytical practice. The goal here is to discuss both the positive and negative potential of this process. I end by reflecting on how Larry’s intellectual commitment to radical contextualism also works as a personal form of radical contextuality.  相似文献
