Past research indicates that anticipating adverse outcomes, such as early death (fatalism), is associated positively with adolescents’ likelihood of engaging in risky behaviors. Health researchers and criminologists have argued that fatalism influences present risk taking in part by informing individuals’ motivation for delaying gratification for the promise of future benefits. While past findings highlight the association between the anticipation of early death and a number of developmental outcomes, no known research has assessed the impact of location in a context characterized by high perceptions of fatality. Using data from Add Health and a sample of 9,584 adolescents (51 % female and 71 % white) nested in 113 schools, our study builds upon prior research by examining the association between friends’, school mates’, and individual perceptions of early fatality and adolescent risk behaviors. We test whether friends’ anticipation of being killed prior to age 21 or location in a school where a high proportion of the student body subscribes to attitudes of high fatality, is associated with risky behaviors. Results indicate that friends’ fatalism is positively associated with engaging in violent delinquency, non-violent delinquency, and drug use after controlling for individual covariates and prior individual risk-taking. Although friends’ delinquency accounts for much of the effect of friends’ fatalism on violence, none of the potential intervening variables fully explain the effect of friends’ fatalism on youth involvement in non-violent delinquency and drug use. Our results underscore the importance of friendship contextual effects in shaping adolescent risk-taking behavior and the very serious consequences perceptions of fatality have for adolescents’ involvement in delinquency and drug use.  相似文献

The hundredth anniversary of the original publication of Eugen Ehrlich's Fundamental Principles of the Sociology of Law is nearly upon us. The book earned high praise from Oliver Wendell Holmes, Roscoe Pound, and Karl Llewellyn as one of the outstanding works of its time. Ehrlich has been identified as an early legal realist, a pioneering figure in legal sociology, and a leading theorist of legal pluralism. In this retrospective review, I explain the strengths and weaknesses of this classic book. Ehrlich articulated an unsurpassed account of dynamic social‐legal change, an account that remains fresh and timely today.  相似文献

对一份文件最早制成时间的检验一直以来都是全世界文检界的难题之一。核实可疑文件的制成时间没有统一的方法,目前主要通过对纸张、墨迹、打字机、复印机、打印机、传真机、印刷品,以及笔迹和签名等因素的检验来确定一份文件的制成时间。文件检验人员需要充分利用他们手中的文件的内容及文件周边信息所反映出来的条件和材料,进而得出结论。  相似文献

The recent economic and fiscal crisis provides an opportunity for learning lessons of general and practical relevance about how governments face shocks affecting their financial conditions. This article draws on the resilience concept to investigate the organizational capacities that are deployed and/or built by local governments (LGs) to respond to such shocks, looking at their combinations and interactions with environmental conditions. The article presents the results of a multiple‐case analysis of 12 European LGs across Austria, Italy and England. The analysis allows us to highlight and operationalize different patterns of financial resilience, that is, self‐regulation, constrained or reactive adaptation, contented or powerless fatalism, that are the result of the interaction and development over time of different internal and external dimensions.  相似文献

The purpose of this article is to examine how various forms of reasoning both can and should be used to decide cases in the common law tradition. I start by separating positive questions about what the law is from normative questions about what the law ought to be. Next, I present a Peircean account of three main forms of reasoning – deduction, induction and abduction – and examine how they can be used by judges to decide cases in the common law. Finally, I argue that the three forms of reasoning can be used to answer both kinds of questions, but in different ways. All three forms of reasoning can be used to answer questions of positive law, while questions of normative law present a special case that may require the use of aesthetic judgments of taste in the formation of a legal hypothesis.  相似文献

The self-concerns and social expectations that are part of the identity development process may lead adolescents to think that others survey them for signs of individuality. The novelty of identity development may also lead to feelings of uniqueness and invulnerability. The imaginary audience and personal fable may therefore stem from identity development and not from the emergence of formal operations. In this study high school and first-year university students (N=255) completed measures of adolescent egocentrism, identity development, and formal operations. Egocentrism was moderately associated with higher scores on identity crisis and identity achievement, and with lower scores on identity diffusion. There was no significant relationship between egocentrism and the emergence of formal operations.Received his M.Sc. and Ph.D. from the University of Victoria.

This article reviews the experience of SEMATECH as a model for high-technology research consortia. SEMATECH's original aims of developing next-generation manufacturing technology proved hard to achieve, and the program has refocused on generic technology and the equipment industry infrastructure. Though more modest, these new objectives have produced significant tangible results. The study considers the reasons for the change and implications for consortium design. This is contrasted with the history of other major collaborative research programs in Japan, Europe, and the United States.  相似文献
