Emotion regulation is critical for adolescent functioning. Theories on the subject have evolved rapidly in recent years and have led to a more contextualized and dynamic conceptualization of emotion regulation processes. In this paper, based on the distinction between emotion regulation strategies and abilities, we propose future directions for research on emotion regulation development in adolescence. We first present evidence that emotional, cognitive, and social changes that occur in adolescence are central in emotion regulation development. We then review empirical findings on emotion regulation development by tying them to their conceptual foundations. We discuss their limitations and argue that building better conceptual clarity is essential to study emotion regulation. Because current knowledge on recent concepts that emerged in adult-based models remains limited and contested in adolescence, we end this article by discussing new research perspectives to provide a better understanding of the topic. We stress the need for researchers in the field to adopt a more contextualized and person-oriented approach, to combine different time scales and methods, and examine the predictors of emotion regulation as well as its outcomes. 相似文献

Despite extensive research on multiracial youth in recent years, to date, no empirical studies have analyzed how racial context may affect biracial adolescents' sense of belonging in a social institution beyond families. In this study, we examine how the racial makeup of the student body affects self-identified biracial adolescents' school attachment. Using data from the National Longitudinal Study of Adolescent Health, we find that the proportions of white or black students in school significantly affect the school attachment of Hispanic/black, Asian/black, and American Indian/black biracial adolescents, but school racial composition in general has little influence on biracial adolescents with a partial-white identification (i.e., black/white, Hispanic/white, Asian/white, and American Indian/white). Our analyses also show that on average, students of most biracial groups display lower school attachment than their corresponding monoracial groups, but the differences from the monoracial groups with the lower school attachment are generally small. We discuss the implications of our findings for biracial adolescents' perceived racial boundaries and contemporary American race relations. 相似文献

So far, limited work has focused on women's experiences of mothering in the context of domestic violence. This article presents the findings of a study that investigated women's experiences of mothering in the context of domestic violence and, while it accounts for the difficulties and challenges these women face, it emphasises their desire to be ‘good’ mothers and the strategies they develop in order to achieve ‘good’ mothering. The findings demonstrate that abused women typically strive to be ‘good’ mothers, which requires them to put their children first and to protect and care for them. The recognition of these strategies provides ground to question current professional practices and to develop interventions that will best support women and children living with domestic violence.

This article examines the link between the domain and level of occupation, on the one hand, and use of media, including internet, on the other. It adds to this investigation an analysis of identity in its relation to media use and accessibility. It challenges the hypothesis of a strong correlation between level of occupation and use and accessibility to media. It reveals complex phenomena of social homogenization and differentiation. Data is extracted from a sample of workers who completed a questionnaire which focused on use of media. 相似文献

A Bayesian multi-category kernel classification method is proposed. The algorithm performs the classification of the projections
of the data to the principal axes of the feature space. The advantage of this approach is that the regression coefficients
are identifiable and sparse, leading to large computational savings and improved classification performance. The degree of
sparsity is regulated in a novel framework based on Bayesian decision theory. The Gibbs sampler is implemented to find the
posterior distributions of the parameters, thus probability distributions of prediction can be obtained for new data points,
which gives a more complete picture of classification. The algorithm is aimed at high dimensional data sets where the dimension
of measurements exceeds the number of observations. The applications considered in this paper are microarray, image processing
and near-infrared spectroscopy data. 相似文献

This paper presents the results of a survey aimed at gauging the potential acceptance of a collaborative and Web 2.0 inspired scholarly communication sector. While this sector has seen the birth of a multitude of innovative initiatives, there is still little empirical evidence of the acceptance of such initiatives by researchers. We received 349 completed questionnaires from researchers of many different disciplines. The results of the survey show that there is a strong positive attitude towards Web 2.0 and open publishing approaches. However, the major challenge still resides in combining free dissemination of results with robust and reliable quality control mechanisms. 相似文献

Concerns about potentially misleading reporting of pharmaceutical industry research have surfaced many times. The potential for duality (and thereby conflict) of interest is only too clear when you consider the sums of money required for the discovery, development and commercialization of new medicines. As the ability of major, mid-size and small pharmaceutical companies to innovate has waned, as evidenced by the seemingly relentless decline in the numbers of new medicines approved by Food and Drug Administration and European Medicines Agency year-on-year, not only has the cost per new approved medicine risen: so too has the public and media concern about the extent to which the pharmaceutical industry is open and honest about the efficacy, safety and quality of the drugs we manufacture and sell. In 2005 an Editorial in Journal of the American Medical Association made clear that, so great was their concern about misleading reporting of industry-sponsored studies, henceforth no article would be published that was not also guaranteed by independent statistical analysis. We examine the precursors to this Editorial, as well as its immediate and lasting effects for statisticians, for the manner in which statistical analysis is carried out, and for the industry more generally. 相似文献

Doubly truncated survival data arise when event times are observed only if they occur within subject specific intervals of times. Existing iterative estimation procedures for doubly truncated data are computationally intensive (Turnbull 38:290–295, 1976; Efron and Petrosian 94:824–825, 1999; Shen 62:835–853, 2010a). These procedures assume that the event time is independent of the truncation times, in the sample space that conforms to their requisite ordering. This type of independence is referred to as quasi-independence. In this paper we identify and consider two special cases of quasi-independence: complete quasi-independence and complete truncation dependence. For the case of complete quasi-independence, we derive the nonparametric maximum likelihood estimator in closed-form. For the case of complete truncation dependence, we derive a closed-form nonparametric estimator that requires some external information, and a semi-parametric maximum likelihood estimator that achieves improved efficiency relative to the standard nonparametric maximum likelihood estimator, in the absence of external information. We demonstrate the consistency and potentially improved efficiency of the estimators in simulation studies, and illustrate their use in application to studies of AIDS incubation and Parkinson’s disease age of onset. 相似文献

This paper draws upon the findings of a study that looked at women's experiences of mothering in the context of co-occurrence of domestic violence and child abuse, and considers the issue of women's violence towards children – while acknowledging the fact that men are the main perpetrators of violence towards women and children in these families. The paper first explores the relationship between women's victimization and women's violence, and suggests that women's abuse of their children can be seen as a consequence of their own experiences of domestic violence. The findings nonetheless suggest that abused women have agency, and therefore have responsibilities when they chose to use violence towards their children. The paper also considers the feelings of guilt and blame that tend to arise in these circumstances. Implications for research, policy and practice are identified. 相似文献
