Adolescents may engage in risk behaviors that jeopardize their futures. Although adolescent risk-taking has long been attributed
to faulty decision making, surprisingly little research has directly examined this link. This study examined the role of deliberative
decision making (the tendency to consider options and consequences before making a decision) and social contextual variables
(parenting and friend influences) in alcohol and drug use, risky sex, and delinquency. Participants were 7,748 adolescents
(50% female) in grades 7–11 from the Add Health dataset (M age = 14.87, SD = 1.54). Hierarchical regression analyses revealed that deliberative decision making and contextual variables
were associated with risk behavior concurrently and 1 year later. Furthermore, deliberative decision making interacted with
social contextual variables in some models, indicating that deliberative decision making may be especially important in certain
contexts. These findings suggest that both cognitive and social factors need to be considered to explain adolescents’ decisions
to engage in risk behavior. 相似文献

Despite limited empirical evidence, there is growing concern that junk food availability in schools has contributed to the childhood obesity epidemic. In this paper, we estimate the effects of junk food availability on body mass index (BMI), obesity, and related outcomes among a national sample of fifth graders. Unlike previous studies, we address the endogeneity of the school food environment by controlling for children's BMI at school entry and estimating instrumental variables regressions that leverage variation in the school's grade span. Our main finding is that junk food availability does not significantly increase BMI or obesity among this fifth‐grade cohort despite the increased likelihood of in‐school junk food purchases. The results are robust to alternate measures of junk food availability including school administrator reports of sales during school hours, school administrator reports of competitive food outlets, and children's reports of junk food availability. Moreover, the absence of any effects on overall food consumption and physical activity further support the null findings for BMI and obesity. 相似文献

Inter-firms R&D collaborations are often seen as an effective mean to access new resources, to innovate and/or to enter new markets in a turbulent environment characterized by fierce competition. However, all R&D partnerships do not have the same strategic importance. We analyze the strategic features of two types of partnerships that are seldom compared in the academic literature on R&D alliances: EU-sponsored inter-firms collaborations on the one hand, and non-sponsored, spontaneous inter-firm collaborations on the other. We compare their incentives and coordination mechanisms, and derive theoretical propositions that we test empirically. Our econometric analysis uses original data on (sponsored and non-sponsored) projects conducted by participants in the 5th and 6th European R&D Framework Programs. Our empirical findings support our main propositions. EU-funded collaborations are more exploratory and more focused on peripheral competences than spontaneous R&D collaborations. They are also less flexible, due to rigid monitoring rules which are nevertheless crucial to the projects?? success. However, there is no major difference between the different types of EU-sponsored collaborations, which pleads for a simplification of these policy instruments. 相似文献

The global ubiquity of cloud computing may expose consumers' sensitive personal data to significant privacy and security threats. A critical challenge for the cloud computing industry is to earn consumers' trust by ensuring adequate privacy and security for sensitive consumer data. Regulating consumer privacy and security also challenges government enforcement of data protection laws that were designed with national borders in mind. From an information privacy perspective, this article analyses how well the regulatory frameworks in place in Europe and the United States help protect the privacy and security of sensitive consumer data in the cloud. It makes suggestions for regulatory reform to protect sensitive information in cloud computing environments and to remove regulatory constraints that limit the growth of this vibrant new industry. 相似文献

Abstract Annie Besant was a Victorian radical whose outspoken views included advocacy of women's rights and opposition to British imperial policies. In her mid-forties she went to live in India. Contesting British attempts to Westernize Indian society, Besant found herself in the seemingly anomalous position of defending traditional Indian patriarchy and resisting efforts to reform the status of Indian women. Such conservatism brought on Besant criticism not only from Western liberals and Christian missionaries, but also from many Indian social reformers. When she gradually shifted her views and voiced her support for Indian women's rights, Indian nationalists condemned her as a British imperialist. The conflict between loyalty to national heritage and opposition to traditional patriarchy is one that colonized women have commonly experienced. By examining how an anti-imperialist British feminist responded to the question of women's reform in India, this paper offers another perspective on the complexities of this dilemma. 相似文献

We investigate the effect of fiscal institutions such as the strength of the finance minister in the budget process and deficits on interest rate spreads of Eurozone countries. Deficits significantly increase risk premia measured by relative swap spreads. The effect of deficits is significantly lower under EMU. This effect partly results from neglecting the role of fiscal institutions. After controlling for institutional changes, fiscal policy remains a significant determinant of risk premia in EMU. Better institutions are connected with lower risk premia. Furthermore deficits matter less for risk premia in countries with better institutions. Markets acknowledge that better institutions reduce fiscal difficulties rendering the monitoring of annual developments less important. 相似文献

The goal of this study was to examine the relationship between family dysfunction and wanted, unwanted, and illegal sexual experiences that occurred during childhood and adolescence. Three hundred fifty-three subjects from a sexual abuse clinic, a family practice clinic, and a family planning clinic anonymously completed a survey on childhood sexual experiences and physical violence, family substance abuse, violence toward others, and family quality. Overall, 50% had had unwanted (USE) and wanted sexual experiences (WSE) before they turned 18. Subjects in the sexual abuse clinic had the highest percentage (90%) of unwanted or illegal sexual experiences, followed by the family planning subjects (40%) and the family practice subjects (30%). Both USE and WSE were related to family dysfunction scores, even when they were controlled for demographic influences. Family dysfunction scores were highest for those who reported USE and legal WSE and were lowest for those who reported no USE or WSE. 相似文献
