Bullying in schools has been found to be widespread. The popular stereotype of a bully, supported by theories based on the social skills deficit model, is of a powerful but 'oafish' person with little understanding of others. In this article, we trace the origin of this view, and present an alternative view: that some bullies, at least, will need good social cognition and theory of mind skills in order to manipulate and organise others, inflicting suffering in subtle and damaging ways while avoiding detection themselves. Such skills, although likely to be utilised in all bullying, may be particularly useful for ringleader bullies and in the indirect forms of bullying which are more common between girls. Suggestions for further research in this area are made, and implications for anti-bullying work briefly discussed.  相似文献

Critiques of the essentialising tendencies of nationalist discourse are well established in the social sciences—particularly in anthropology. This article builds on the calls for a more processual approach to national identity. It focuses not only on the problematic essentialism of discourses of national identity, but also on their inherent teleology. Social scientists have shared with nationalists a view of national identity as a problem that needs to be solved, and in doing so have adopted a teleological view that assumes that at some point in the future resolution is both possible and desirable. Picking up on recent theorisations of identity, the article argues that identity is inherently irresolvable, and for this reason we are better off investigating not the content of particular national identities, but the processes through which identities are debated—or indeed identity itself as a category is debated. The article concerns national identity in Malta, particularly the role of historians in articulating the identity debates. It links controversies within the historical community to the distinctive polarities of Maltese party politics, which developed in colonial Malta and continue into the post-colonial era. Although initially concerned with defining the content of national identity, political and historical debate shifted in the late twentieth century to focus on how it should be defined—and indeed whether identity was a useful category for describing Malta and its people. The article argues that this shift from content to process should be acknowledged by analysts of national identity, who should revise their analyses accordingly.  相似文献

We study estimation of multivariate densities p of the form p(x) = h(g(x)) for x ∈ ?(d) and for a fixed monotone function h and an unknown convex function g. The canonical example is h(y) = e(-y) for y ∈ ?; in this case, the resulting class of densities [Formula: see text]is well known as the class of log-concave densities. Other functions h allow for classes of densities with heavier tails than the log-concave class.We first investigate when the maximum likelihood estimator p? exists for the class P(h) for various choices of monotone transformations h, including decreasing and increasing functions h. The resulting models for increasing transformations h extend the classes of log-convex densities studied previously in the econometrics literature, corresponding to h(y) = exp(y).We then establish consistency of the maximum likelihood estimator for fairly general functions h, including the log-concave class P(e(-y)) and many others. In a final section, we provide asymptotic minimax lower bounds for the estimation of p and its vector of derivatives at a fixed point x(0) under natural smoothness hypotheses on h and g. The proofs rely heavily on results from convex analysis.  相似文献

Abstract

After a needs assessment indicated that male students underutilized campus health services, the San Francisco State University Student Health Service developed a coordinated complement of outpatient health services for men. The authors review their experience in developing, implementing, operating, and evaluating this ongoing clinical service. The needs assessment and subsequent program evaluation data suggest that male students on a large, culturally diverse, urban campus would respond favorably to targeted, multidisciplinary health initiatives that incorporate the principles of health promotion and disease prevention.  相似文献

This study reports the findings of a general population telephone survey (N =2500) conducted in Ontario, which was designed to examine behaviour, knowledge and attitudes related to responsible and problem gambling using a combination of closed- and open-ended questions. When asked to identify ‘signs and symptoms of problem gambling’ or to define responsible gambling, most respondents focused on financial issues suggesting that the general population has a very narrow view of the issue of problem gambling. The majority (65.8%) are not aware of any initiatives to reduce problem gambling; however, we found that people who participate in slots and instant lotteries were more likely to report being aware of initiatives to reduce problem gambling. These findings suggest that people do notice the presence of the help-line number on tickets and slot machines. The survey also examined responsible gambling behaviour and biases in beliefs about gambling.  相似文献

Survival models are widely used in demography to analyse the timing of events such as death or leaving school. However, for events such as marriage or childbirth that are not experienced by everyone, standard survival analysis conflates the speed of progressing to an event with the proportion that never experience the event. The problem can be overcome by applying a ‘split population’ or ‘cure’ survival time model which splits the population into those who eventually experience the event and those who do not, and determines the speed of progression for the former. This paper demonstrates the use of split-population models in examining variables which affect the propensity and timing of additional births. The data analysed are from a sample of women from the 2001 Household, Income and Labour Dynamics in Australia (HILDA) Survey (N = 4,611). We model the propensity and time to have another child given sex composition of existing children, number of siblings and age at first birth for three cohorts of women. The study finds evidence of a preference for a mixed-sex composition, and an increased propensity for women with two boys to try for a third child. Women in later cohorts tend to have more children if they themselves come from larger families. Age at first birth is strongly associated with the propensity to have another child and with the speed of progression.  相似文献
