Investigating the effects of peer association and parental influence on adolescent substance use: A study of adolescents in South Korea 总被引:1,自引:0,他引:1
The central purpose of this study was to examine whether peer influence has a greater impact on adolescent substance use than parental influence. This was a comparative study that examined cross-cultural applicability by applying the established findings and theoretical suggestions, such as social learning theory and social bonding theory in the United States, to a traditionally non-Western social context (South Korea). Although the theories have firmly established their explicability on adolescent delinquency and substance use in U.S. society, there are relatively few empirical studies to establish its generalizability in societies outside the U.S. and even fewer in such traditionally non-Western societies as South Korea. Using a nationwide sample of self-reported data from 3,188 junior high school students, estimations from multivariate analyses were used to compare the relative importance of peer and parental influence on adolescent substance (alcohol and tobacco) use. The findings from the current study supported both social learning theory and social bonding theory, suggesting that both peer and parental influence are significant in predicting the risks of adolescent substance use. Although parental influence was slightly greater than peer factors, the difference was negligible. The limitations, the unique social context of Korean society, and future research implications are then discussed. 相似文献

A framework is developed for analyzing the impacts of information technology on politics and the public sector. By analyzing the findings in all relevant empirical research studies published in 16 scholarly journals during a six-year period, the incidence and direction of key impacts of IT are specified. In general, there is a limited number of empirical studies, with more case studies than studies based on survey-research, more analyses of U.S. politics and government than ones on other advanced democracies, and more focus on the local level than the national level. Overall, the research concludes that the impacts of information technology are generally positive, especially regarding the enhancement of capabilities, such as efficiency, effectiveness, and information quality. Impacts are more mixed on patterns of individual and group interactions and on orientations toward decision and action. The area in which the research identifies the most negative effects is the impacts on values, such as privacy, legal security and job enhancement. 相似文献

This paper demonstrates that the role of plea bargaining as a screening device depends neither on the commitment to trial
nor on the commitment to some prosecutorial expenditures. In a situation where a prosecutor cannot commit to trial nor spends
resources to obtain more evidence, I find a semi-separating equilibrium in which the prosecutor makes an offer that can be
accepted only by the guilty defendant with some positive probability, and then, if the offer is rejected, he proceeds to trial,
based on his updated belief. I also consider the prosecutor’s decision to choose the amount of (per capita) prosecutorial
expenditures both in the commitment case and in the noncommitment case, and argue that an increase in the per capita expenditure
may reduce the gross expenditures on prosecution by lowering the chance of trial. 相似文献

Despite longstanding scholarly attention to professions in the US, the relationships between lawyers and non-lawyer professionals are not well explained. Socio-legal studies and studies of professions often take for granted conflicts as the nature of inter-professional relationships. However, this understanding ignores the possibility of cooperation in which a set of professional occupations jointly attains a limited supply of necessary resources. Based on the ecological concepts of interactions and environments, the author discusses the impact of non-lawyer professions on the population of lawyers in an attempt to understand the relationships between the occupational groups. Using the panel data model to test data from 50 US states and the District of Columbia over a 10-year period, the study reveals that the legal profession is in cooperation with professionals in financial and law-affiliated areas. The analysis of ecological interactions moves beyond conflict-oriented understanding of professional occupations, and further, exhorts for the exploration of various forms of inter-professional relationships. 相似文献

Abstract: There are several areas within mitochondrial DNA that show length heteroplasmy. If the heteroplasmy pattern is unique and consistent for each person, it may be used to support an interpretation of exclusion in identity testing. We investigated whether the length heteroplasmy pattern would be consistent under different amplification conditions. We also determined whether various amplification parameters would affect the homopolymeric cytosine stretches (C‐stretch) in HV1. Monoclonal samples tended to be heteroplasmic after amplification. After several repetitions, C‐stretch patterns of all samples were inconsistent even under the same amplification conditions. Increased PCR cycles and high template concentrations resulted in a more frequent heteroplasmic tendency. These amplification parameters seem to have little effect if samples are not long enough in C‐stretch or total length of the segment from nt 16180 to nt 16193. It is suggested that the pattern of length heteroplasmy cannot be used as an additional polymorphic marker. 相似文献

With the planned US and NATO withdrawal from Afghanistan in 2014 looming ever closer, and Central Asia's own future increasingly in doubt, major powers are all competing to enhance their influence in Central Asia. 2014 may mark a regional tipping point, but none can accurately predict how the regional balance might shift after the NATO withdrawal from Afghanistan. During 2009–2010, the signs of growing Russian dependence on China in terms of economy and energy were palpable, as were the signs of China successfully subordinating Russia to its Central Asian economic agenda. In 2011–2012, it was difficult to see Russia simply acquiescing in its subordination to China without reacting to that situation negatively. Since 2011, to avoid this dependence on China, Russia has vigorously pushed for its regional integration schemes. 2011 marked the launch of the US “New Silk Road” initiative. Great power regional integration schemes, however, undermine both regional and national development. 相似文献

One of the most interesting and possibly disturbing developments in U.S. trademark law in recent decades is the rise of a federal remedy for trademark dilution. Dilution law in theory provides a remedy for owners of famous trademarks when others use similar marks in ways that blur or tarnish the famous mark. This article focuses on attempts by courts and scholars to formulate a methodology for proving this elusive cause of action. The article offers a history of dilution regulation and analyzes and critiques representative empirical approaches to proving dilution, with a focus on dilution by blurring. 相似文献

New information technologies have the potential for transforming the ways governments are organized, the activities they perform, how they perform them, and the nature of work itself. Governments in the U.S. and Scandinavia have followed fundamentally different approaches to the introduction of computing and to dealing with its effects. These differences in approach to automation have influenced each country's view of the role of government in anticipating and dealing with the effects of changes in computer technology on the public service workforce. 相似文献
