The purpose of this study was to evaluate the outcomes following participation in the ESPACE parents' workshop. A group of 55 parents who participated in the program, implemented in elementary schools in the Quebec city region, was compared to a group of 217 parents who did not attend the prevention workshop. The results revealed that attending parents suggested more adequate interventions to the vignette depicting a hypothetical situation of sexual abuse compared to nonattending parents. Attending parents are found to be more likely to suggest interventions sustaining the child in her own problem-solving process, seek help from specialized agencies, and attempt to offer emotional support to the victim. Data also reveal that the parents workshop has a positive outcome on knowledge. While the workshop is associated with beneficial outcomes, attendance rates are low. The findings are discussed in the context of identifying means to foster parent involvement in the prevention of child abuse. 相似文献

Tichotillomania presents challenges to clinicians in various areas including assessment, treatment, and research. Characterized by an irresistible urge to pull out one's hair, which is preceded by tension and followed by relief or pleasure, trichotillomania can cause significant impairment and distress to those who suffer from it. Possible hypothesized causes include a biological basis for hair-pulling, as well as pulling in response to stressors in life. Several assessment techniques to measure the severity of trichotillomania exist, each of which has advantages and disadvantages in establishing a diagnosis. Because it is still a relatively poorly understood disorder, treatment options for patients reporting these behaviors are limited and generally are confined to pharmacological therapy and habit-reversal behavior therapy. Mansueto, Stemberger, Thomas, and Golomb have published a compelling comprehensive behavioral model that attempts to explain the various cues and factors in trichotillomania. It is useful to consider trichotillomania a biological, psychological, and social phenomenon requiring further research regarding the interaction of these variables in advancing the understanding of the disorder. 相似文献

Cross-national research claims increasing attention, due in part to a growing awareness of worldwide interdependence. One of the most intriguing areas of research is the comparison of perceptions about the quality of life. However, even the first attempt to compare cross-national quality of life perceptions (Cantril, 1965) raised a question which still remains unanswered: What do the differences between countries mean? Presumably differences in income, in the objective conditions of the major life domains such as housing, health and employment, and in demographic variables account for some of the difference among countries' reported quality of life satisfaction. But how can these factors be separated from other non-random factors? The term we use for the latter is “cultural bias”. By cultural bias we mean the systematic cross-national differences in quality of life perceptions which are not explained by objective measures of quality of life nor by demographic factors. Ordinarily these culture-specific biases are acquired during the socialization process almost as automatically and unconsciously as one learns one's mother tongue. Cultural bias is manifested in the tendency for members of a particular culture to be optimistic or pessimistic, confident or cautious in evaluating their social and physical environment and in revealing these evaluations to others. Thus, our conception of cultural bias has something in common with the idea of national character, but it is more limited in scope. In this paper we discuss the problem of isolating the impact of cultural bias from the other factors affecting how people perceive their quality of life and measuring it. We describe a method which is capable of doing this and report the results of using it to measure the relative cultural bias between respondents in Springfield, Illinois and Aixen-Provence, France. 相似文献

We examine members' spontaneous accounts for joining and participating in an online emo forum. The Internet and social networking sites are central features of contemporary youth cultures; the analysis of interaction on emo forums can thus provide a way of appreciating emo as a ‘Community in Practice’. We analyse popular discussion threads collected from a key emo website, using membership categorisation and conversation analysis. In these threads, members introduce themselves and account for joining and posting pictures in response to a prior request to do so. Analysis shows that newbies establish their emo attributes and hence entitlement to participate while dismissing emo-related motivation for joining the forum, claiming instead a desire to relieve boredom. Participants similarly accounted for posting photos of themselves and for producing fan pics as due to boredom. We show how claiming to be bored allows members to engage with the group while negotiating potentially problematic inferences that attend subcultural membership. We conclude that our approach provides a useful methodology for furthering our understanding of an important aspect of contemporary youth subcultures. 相似文献

When monitoring highly capable processes, it is often desirable to tolerate small instabilities in order to avoid tempering. One approach in this setting is to monitor the capability of the process dynamically and signal if the estimated capability reaches an unacceptably low level. We suggest that monitoring the probability of the next item not falling between the specification limits is a more natural scale to evaluate risk, and offers appreciable flexibility. We use a statistical model and a window of data to evaluate this probability and decide if the process should be halted immediately based on that estimate. The properties of this method are explored numerically and a case study is provided. 相似文献

The weighted likelihood is a generalization of the likelihood designed to borrow strength from similar populations while making minimal assumptions. If the weights are properly chosen, the maximum weighted likelihood estimate may perform better than the maximum likelihood estimate (MLE). In a previous article, the minimum averaged mean squared error (MAMSE) weights are proposed and simulations show that they allow to outperform the MLE in many cases. In this paper, we study the asymptotic properties of the MAMSE weights. In particular, we prove that the MAMSE-weighted mixture of empirical distribution functions converges uniformly to the target distribution and that the maximum weighted likelihood estimate is strongly consistent. A short simulation illustrates the use of bootstrap in this context. 相似文献

The minimum averaged mean squared error nonparametric adaptive weights use data from m possibly different populations to infer about one population of interest. The definition of these weights is based on the properties of the empirical distribution function. We use the Kaplan-Meier estimate to let the weights accommodate right-censored data and use them to define the weighted Kaplan-Meier estimate. The proposed estimate is smoother than the usual Kaplan-Meier estimate and converges uniformly in probability to the target distribution. Simulations show that the performances of the weighted Kaplan-Meier estimate on finite samples exceed that of the usual Kaplan-Meier estimate. A case study is also presented. 相似文献

The paper describes the dynamics of employment at a firm and sector level in French industry and examines how far technological innovation can give account of it. We use a sample of 15,186 firms, over the period 1986–90. The two facts we want to explain at a firm and sector level are the net change in employment and the micro turmoil (transfers between competing firms). Innovating firms and sectors create jobs more than others over the medium run (5 years). Process innovation is more about job creation than product innovation at the firm level, but the converse is true at the sector level. This paradox is probably due to substitution effects (creative destruction). 相似文献
