Two cross-sectional studies investigated media influences on adolescents’ substance use and intentions to use substances in
the context of exposure to parental and peer risk and protective factors. A total of 729 middle school students (n = 351, 59% female in Study 1; n = 378, 43% female in Study 2) completed self-report questionnaires. The sample in Study 1 was primarily African-American
(52%) and the sample in Study 2 was primarily Caucasian (63%). Across the two studies, blocks of media-related cognitions
made unique contributions to the prediction of adolescents’ current substance use and intentions to use substances in the
future above and beyond self-reported peer and parental influences. Specifically, identification with and perceived similarity
to media messages were positively associated with adolescents’ current substance use and intentions to use substances in the
future, and critical thinking about media messages and media message deconstruction skills were negatively associated with
adolescents’ intention to use substances in the future. Further, peer influence variables (e.g., peer pressure, social norms,
peer substance use) acted as risk factors, and for the most part, parental influence variables (e.g., parental pressure to
not use, perceived parental reaction) acted as protective factors. These findings highlight the importance of developing an
increased understanding of the role of media messages and media literacy education in the prevention of substance use behaviors
in adolescence. 相似文献

An institution that has shown great promise in addressing the revitalization of declining central cities is Business Improvement Districts (BIDs). These private governments provide supplemental municipal services such as sanitation, security, and marketing to independent businesses in underserved commercial areas. By 1999, 44 U.S. states had legislation that enables and dictates the formation process and structure of BIDs. The surprising element of this legislation is the wide variation in approval needed to form a BID over a proposed geographical area. Some states require as little as 20 percent approval of proposed members and others as much as 75 percent approval to allow formation of a BID. This variation in state statutes likely influences the use of BIDs. Results highlight that relatively easier state enabled collective action positively impacts the creation of BIDs, the limited effects of tax expenditure limitations on the formation of BIDs and the positive impacts that new development has on the number of BIDs per state. 相似文献

General practitioners (GPs) are assumed to occupy an important position in the prevention of suicide through the introduction of risk assessment techniques commonly used in psychiatric practice. Despite this theoretical role for primary care services, it remains unclear how frequently GPs implement risk assessment in patients who may be vulnerable to suicide. To address this, a retrospective survey of probable suicides was conducted within a primary care setting utilizing a questionnaire of GPs who had experienced a patient suicide and was augmented by hospital and coroners' records. 85% of questionnaires were returned and 61 deaths were adjudged as suicides during the year long census period. 75% of suicides were male and 54% were aged under 35.28% were in contact with psychiatric services prior to death, although 60% had some diagnosis of mental disorder. GPs had little knowledge of a patient's life circumstances in up to half of cases. Recording of risk assessment occurred in 38% of subjects, was positively associated with prior psychiatric contact (p = 0.001) but negatively associated with presence of physical illness (p = 0.004), older patient age (p = 0.04), and GPs length in practice (p = 0.05). One GP felt their suicide case was preventable. The low rate of risk assessment and limited knowledge of patient lifestyle point to the need for active engagement of GPs in future suicide prevention strategies and should influence the content of training programs in primary care. 相似文献

Evidence is presented regarding strengths and limitations of portfolio approaches as applied to diversifying export earnings. An empirical application using data from Malawi, Tanzania, and Zimbabwe is used to demonstrate these strengths and limitations. Modifications of the typical portfolio approach to export diversification are presented; these modifications help make the approach more plausible for use in developing countries. The modified approach is shown to provide guidance to policymakers who seek simultaneously to increase export earnings and reduce their instability. 相似文献

Because there has been considerable interest in the Japanese management model, this study explores its limitations for the American setting and particularly the American public sector. These limitations include (1) cultural barriers, (2) the incompleteness of the model, and (3) undesirable elements in the model. This analysis concludes that there is little new in humanistic or participative terms to be found in the Japanese approach. Despite several objectionable elements in the model, some of its devices are instructive and may be carefully adapted to public sector use, but adoption of the whole model is unlikely and undesirable. 相似文献
