This study examined to what extent bullying behavior of popular adolescents is responsible for whether bullying is more or less likely to be accepted or rejected by peers (popularity-norm effect) rather than the behavior of all peers (class norm). Specifically, the mean level of bullying by the whole class (class norm) was split into behavior of popular adolescents (popularity-norm) and behavior of non-popular adolescents (non-popularity-norm), and examined in its interaction with individual bullying on peer acceptance and peer rejection. The data stem from a peer-nominations subsample of TRAILS, a large population-based sample of adolescent boys and girls (N = 3312). The findings of multilevel regression analyses demonstrated that the negative impact of individual bullying on peer acceptance and the positive impact on peer rejection were particularly weakened by bullying by popular adolescents. These results place the class-norm effects found in previous person-group dissimilarity studies in a different light, suggesting that particularly bullying by popular adolescents is related to the social status attached to bullying.

While significant heritability for childhood aggression has been claimed, it is not known whether there are differential genetic and environmental contributions to proactive and reactive forms of aggression in children. This study quantifies genetic and environmental contributions to these two forms of aggression in an ethnically diverse urban sample of 9–10 year old twins (N = 1219), and compares results across different informants (child self-report, mother, and teacher ratings) using the Reactive–Proactive Aggression Questionnaire (RPQ). Confirmatory factor analysis of RPQ items indicated a significant and strong fit for a two-factor proactive–reactive model which was significantly superior to a one-factor model and which replicated across gender as well as the three informant sources. Males scored significantly higher than females on both self-report reactive and proactive aggression, findings that replicated on mother and teacher versions of the RPQ. Asian–Americans scored lower than most ethnic groups on reactive aggression yet were equivalent to Caucasians on proactive aggression. African–Americans scored higher than other ethnic groups on all measures of aggression except caregiver reports. Heritable influences were found for both forms of aggression across informants, but while boys’ self-reports revealed genetic influences on proactive (50%) and reactive (38%) aggression, shared and non-shared environmental influences almost entirely accounted for girls’ self-report reactive and proactive aggression. Although genetic correlations between reactive and proactive aggression were significant across informants, there was evidence that the genetic correlation was less than unity in boys self reported aggression, indicating that genetic factors differ for proactive and reactive aggression. These findings provide the first evidence for varying genetic and environmental etiologies for reactive and proactive aggression across gender, and provide additional support for distinction between these two forms of aggression.  相似文献

While considerable ink has been spilt over the rejection of idealism by Bertrand Russell and G.E. Moore at the end of the 19th Century, relatively little attention has been directed at Russell’s A Critical Exposition of the Philosophy of Leibniz, a work written in the early stages of Russell’s philosophical struggles with the metaphysics of Bradley, Bosanquet, and others. Though a sustained investigation of that work would be one of considerable scope, here I reconstruct and develop a two-pronged argument from the Philosophy of Leibniz that Russell fancied—as late as 1907—to be the downfall of the traditional category of substance. Here, I suggest, one can begin to see Russell’s own reasons—arguments largely independent of Moore—for the abandonment of idealism. Leibniz, no less than Bradley, adhered to an antiquated variety of logic: what Russell refers to as the subject-predicate doctrine of logic. Uniting this doctrine with a metaphysical principle of independence—that a substance is prior to and distinct from its properties—Russell is able to demonstrate that neither a substance pluralism nor a substance monism can be consistently maintained. As a result, Russell alleges that the metaphysics of both Leibniz and Bradley has been undermined as ultimately incoherent. Russell’s remedy for this incoherence is the postulation of a bundle theory of substance, such that the category of “substance” reduces to the most basic entities—properties.  相似文献

Since the publication of his book on Zhongyong (Tu 1976), Tu Weiming has worked for more than 30 years on an anthropocosmic reconstruction of the Confucian universe, in which self-transformation is defined both as the starting point and as the necessary vehicle for one’s spiritual journey. This article is primarily intended to examine Tu’s attempts to reconstruct Confucian spirituality but further to take a step forward to argue that in the spiritual world as construed by Confucius and Mencius, the experiential functions as transcendental by which the self initiates and empowers the transformative process. Through exploring the spiritual significance of Confucian experiences, this essay will conclude that although “transcendental experience” is only one of many dimensions in other religious or intellectual traditions, it is the most important path for Confucians by which the self is enabled to become fully integrated with ultimate reality.  相似文献

I seek to reply to the thoughtful and challenging papers by Helen Steward, Saul Smilansky, and John Perry. Steward argues that agency itself requires access to alternative possibilities; I attempt to motivate my denial of this view. I believe that her view here is no more plausible than the view (which she rejects) that it is unfair to hold someone morally responsible, unless he has genuine access to alternative possibilities. Smilansky contends that compatibilism is morally shallow, and that we can see this from the “ultimate perspective.” In reply, I explore the nature of “zooming” arguments, and I contend that even from a somewhat more detached perspective, important features that distinguish us from mere animals can be discerned (even in a causally deterministic universe). Finally, I seek to address Perry’s defense of classical compatibilism. My main objection to his form of compatbilism is that agents must be construed as having a certain kind of “baggage”—even on his own account.

HIV testing and counseling expends considerable HIV prevention resources and offers great opportunities for HIV risk reduction. Individuals who are at risk for HIV and have not been HIV tested are the focus of current targeted testing campaigns and yet persons who are repeatedly tested for HIV often continue engaging in high-risk practices. This study examined HIV testing, risk behaviors, and other medical diagnostic testing practices of men (N = 231) and women (N = 86) attending an inner-city sexually transmitted infections (STI) clinic. Results showed that 75 (23%) participants had not yet been tested for HIV, 45 (14%) had been tested once, and 197 (63%) had been tested two or more times. Patients that had not been tested and those who were repeatedly tested were similar in their risk behaviors; both demonstrated significantly greater risks for HIV than persons tested just once, although repeat testers were more likely to have had a past STI. HIV testing history was minimally associated with other medical testing and health protective practices, such as testicular self-examination, mammography, and having had PAP tests. Results support targeting high-risk untested persons for HIV testing and suggest an urgent need for interventions to reduce risk behaviors among STI clinic patients who repeatedly test for HIV.  相似文献

Gideon Rosen’s [1990 Modal fictionalism. Mind, 99, 327–354] Modal Fictionalist aims to secure the benefits of realism about possible-worlds, whilst avoiding commitment to the existence of any world other than our own. Rosen [1993 A problem for fictionalism about possible worlds. Analysis, 53, 71–81] and Stuart Brock [1993 Modal fictionalism: A response to Rosen. Mind, 102, 147–150] both argue that fictionalism is self-defeating since the fictionalist is tacitly committed to the existence of a plurality of worlds. In this paper, I develop a new strategy for the fictionalist to pursue in response to the Brock–Rosen objection. I begin by arguing that modal fictionalism is best understood as a paraphrase strategy that concerns the propositions that are expressed, in a given context, by modal sentences. I go on to argue that what is interesting about paraphrastic fictionalism is that it allows the fictionalist to accept that the sentence ‘there is a plurality of worlds’ is true without thereby committing her to the existence of a plurality of worlds. I then argue that the paraphrastic fictionalist can appeal to a form of semantic contextualism in order to communicate her status as an anti-realist. Finally, I generalise my conception of fictionalism and argue that Daniel Nolan and John O’Leary-Hawthorne [1996 Reflexive fictionalisms. Analysis, 56, 26–32] are wrong to suggest that the Brock-Rosen objection reveals a structural flaw with all species of fictionalism.

Aspirations, along with attainments, play an important role in shaping well-being. Early in adult life women are more likely than men to fulfill their material goods and family life aspirations; their satisfaction in these domains is correspondingly higher; and so too is their overall happiness. Material goods aspirations refer here to desires for a number of big-ticket consumer goods, such as a home, car, travel abroad and vacation home. In later life these gender differences turn around. Men come closer than women to fulfilling their material goods and family life aspirations, are more satisfied with their financial situation and family life, and are the happier of the two genders. An important factor underlying the turnaround in fulfillment of aspirations for material goods and family life is probably the shift over the course of the life cycle in the relative proportion of women and men in marital and non-marital unions.  相似文献

Borderline personality disorder and externalizing disorders are associated with suicide-related behaviors. The present study examined whether symptoms of borderline personality disorder mediate the relationship between externalizing disorders and suicide-related behaviors. Diagnostic interviews were administered to 344 participants (n = 233 women). Results indicated that symptoms of antisocial personality disorder, alcohol use disorders, and drug use disorders each were significantly associated with suicide threats and self-injurious behavior in women and symptoms of antisocial personality disorder were associated with suicide attempts in women. With the exception of the association between symptoms of alcohol dependence and self-injurious behaviors, borderline personality disorder symptoms mediated or partially mediated all associations between externalizing disorders and suicide-related behaviors in women. These results highlight the importance of assessment and treatment of borderline personality disorder symptoms in individuals with externalizing disorders, particularly in the presence of suicide-related behaviors.
