The problem of adolescent drug use received a great deal of attention both in criminological theory and public policy. Predominant among theories was Akers' social learning theory which examined the role of learning through a process of imitation, modeling, and reinforcement. Public policy led to the development of programs such as Drug Abuse Resistance Education (DARE) that aimed to warn youths of the dangers of drug use. In line with research findings, both theory and policy gave a central role to peers in understanding adolescent drug use. Less attention was given to another important finding in the literature, that those who used drugs often perceived the drugs as solutions to problems. Using social learning theory, the role of perceptions of drug use as an effective problem solver was examined. Results indicated that a more explicit recognition of the use of drugs to deal with problems might inform both theory and policy. 相似文献

Abstract: ‘European identity’ is as much a contested concept as is the role of the European Union in foreign affairs. This article combines the two concepts and introduces a third variable, ‘the Other’, in order to address the following questions: How do non‐Europeans perceive the EU on the world stage? Is a tentative identity as a mediator in foreign affairs conveyed in the EU's conduct of foreign policy? Analysing 10 newspapers, 4 television bulletins, and 830 public surveys from Australia and New Zealand in the first half of 2004, this article argues that the EU's efforts to further democracy and peace are often marginalised in Australian and New Zealand perceptions. Nevertheless, subtle traces of perceptions of the EU as a potent global actor promoting human rights and environmental sustainability and challenging unilateral US policy courses were detected. 相似文献

A series of calcium phosphate standards having calcium/phosphorus (Ca/P) molar ratios of 0.50, 1.00, 1.50, and 1.67, respectively, was prepared for bulk specimen analysis using scanning electron microscopy (SEM) and energy-dispersive X-ray microanalysis (EDXA). The standards were mounted on carbon planchettes as either pure crystals or crystals embedded in epoxy resin. Ten different samples of each embedded and non-embedded standard were analyzed in a JEOL 100 CX electron microscope interfaced with a Kevex 8000 EDXA system using a lithium-drifted silicon detector and a multichannel analyzer. The Ca/P ratios were determined by calculating both net peak intensities without matrix corrections and atomic kappa-ratios using the MAGIC V computer program with ZAF correction factors for quantitative analysis. There was such extensive absorption of phosphorus X-rays in standards embedded in an epoxy matrix that the observed Ca/P ratios were statistically compatible with four different standards ranging in theoretical Ca/P ratios from 1.0 to 1.67. Although the non-embedded crystals showed a greater separation in the Ca/P ratios, both methods of preparation produced serious flaws in analysis. Direct application of the discovery of this caveat to the identification of suspected bone fragments for forensic science purposes is discussed. 相似文献

Within the context of the debate over the recent suspended sentence given to John Stuart Godfrey by Underwood J in the Supreme Court of Tasmania for assisting his elderly mother with her suicide, this article examines some of the more popular arguments for and against the moral acceptability of euthanasia and assisted suicide. This article considers the arguments put forward on the "difference principle" by Rachels and Nesbitt before critically examining the liberal approach to the euthanasia issue as proposed by Kuhse. It is argued that whilst Kuhse is correct to reject the difference principle, she does so for the wrong reasons. The penultimate section of the article provides an overview of the traditional moral view against killing. The final part assesses whether the arguments put forward by proponents of the liberal approach are capable of overcoming this view. 相似文献

Much research on adolescent delinquency pivots on the notion of peer influence. The peer effect that is typically employed
emphasizes the transmission of behaviors and attitudes between adolescents who are directly linked. In this paper, we argue
that to rely solely on those direct social ties to capture peer influence oversimplifies the realities of adolescent society.
We use data from the National Longitudinal Study of Adolescent Health to show that indirect peer relations can exercise independent
influences on adolescent delinquency. Adolescents actively draw on the examples of friends of friends, and even more distal
peers, as they develop their repertoires of action and identity. We argue, however, that this behavior actually reflects adolescents’
ongoing struggle to impress their closest friends and to preserve their social circle. Indeed, the extent to which adolescents
are willing to model the behavior of indirect contacts seems to decline as that behavior becomes more dissimilar from that
of their close friends. Our findings dovetail with an account of the adolescent as a rational actor who struggles for social
acceptance in a complex peer environment which offers conflicting behavioral models.
