Adolescents' Commitment to Developing Talent: The Role of Peers in Continuing Motivation for Sports and the Arts 总被引:2,自引:0,他引:2

The role of peer relationships in supporting or hindering adolescents' talent development has received little research attention, despite the importance of peers in adolescents' lives. We conducted semi-structured in-depth interviews with 41 adolescents talented in sports or the arts, and their parents, to investigate (a) the role of peer relationships in adolescents' continued involvement in their talent activities, (b) possible differences in this role by activity domain, and (c) possible gender differences. Thematic analysis indicated that peers typically played a positive function in supporting the continued involvement of talented adolescents in their talent activities. There were differences in opportunities for peer relationships and social satisfaction between in-school and out-of school activities, but not between activity domains. Both males and females mentioned equally social benefits of such involvement. However, females mentioned receiving negative peer attention more frequently than males, and more often cited social dissatisfaction as a significant contributor to decreased involvement or quitting. 相似文献

The community power debate concluded with each side believing they had won. Political theorists have generalized power, making empirical investigation very difficult; urban scholars have turned their attention to more manageable empirical problems. Rational choice advances the debate, exposing the errors of all sides and facilitating a new approach which transcends structural versus individualist methods. By separating various aspects of power in urban contexts, complementary techniques such as network analysis in a bargaining framework, semi-structured interviewing and the use of text databases permits a comprehensive investigation of agenda-setting and the mobilization of bias. The paper demonstrates the utility of this approach by comparing it to 'regime theory', the latest paradigm of urban research. 相似文献

Recently, the principle of double effect has come under scrutiny by Magnusson who believes it provides a subterfuge for those who act so as to end the lives of their patients. Specifically, he argues that the conceptual distinction between foresight and intention is dubious and, moreover, renders patients vulnerable to involuntary euthanasia. At the same time, Magnusson wants to protect doctors from criminal liability when faced with (what he understands to be) a "devil's choice" between ending the life of a patient or under-treating pain. Hence, Magnusson proposes that, subject to specific conditions, a so-called "defence of necessity" be recognised through either common law doctrine or legislation. However, to safeguard this defence, he must rely on what he most wants to reject: a fundamental aspect of the principle of double effect. 相似文献

Abstract: Samples containing the toxic castor bean protein ricin have been recently seized in connection with biocriminal activity. Analytical methods that enable investigators to determine how the samples were prepared and to match seized samples to potential source materials are needed. One commonly described crude ricin preparation method is acetone extraction of crushed castor beans. Here, we describe the use of solid‐phase microextraction and headspace analysis to determine whether castor beans were processed by acetone extraction. We prepared acetone‐extracted castor bean mash, along with controls of unextracted mash and mash extracted with nonacetone organic solvents. Samples of acetone‐extracted mash and unextracted mash were stored in closed containers for up to 109 days at both room temperature and ?20°C, and in open containers at room temperature for up to 94 days. Acetone‐extracted bean mash could consistently be statistically distinguished from controls, even after storage in open containers for 94 days. 相似文献

I argue that any successful account of permissible self- defence must be action-guiding, or practical. It must be able to inform people’s deliberation about what they are permitted to do when faced with an apparent threat to their lives. I argue that this forces us to accept that a person can be permitted to
use self-defence against Apparent Threats: characters whom a person reasonably, but mistakenly, believes threaten her life.
I defend a hybrid account of self-defence that prioritises an agent’s subjective perspective. I argue that it is sufficient
to render the use of defence permissible if an agent reasonably believes that (a) she is morally innocent, and (b) if she
does not kill this person, then they will kill her. I argue that the correct account of self-defence must distinguish between
whether an agent is permitted to inflict harm, and whether the target is liable to bear that harm. 相似文献
