Ego‐resiliency is an enduring psychological construct reflecting how individuals‐adapt to environmental stressors, conflict, and change which is linked to positive adjustment. Ego‐resiliency has not been examined in Latino youth, despite their high risk for mental health problems; nor have cultural precursors to ego‐resiliency been examined. Given these gaps, we examined whether familism values (supportive, obligation, and referent) were associated with ego‐resiliency and, in turn, depressive problems in Latino adolescents across two time points (N = 123, mean age = 11.53). Results indicated that supportive familism was associated positively with ego‐resiliency and negatively with depressive problems. Ego‐resiliency negatively predicted depressive problems across time, controlling for prior levels, suggesting that ego‐resiliency may have long‐term effects on depressive problems in Latino youth. 相似文献

In this article, we introduce tempered Mittag-Leffler Lévy processes (TMLLP). TMLLP is represented as tempered stable subordinator delayed by a gamma process. Its probability density function and Lévy density are obtained in terms of infinite series and Mittag-Leffler function, respectively. Asymptotic forms of the tails and moments are given. A step-by-step procedure of the parameters estimation and simulation of sample paths is given. We also provide main results available for Mittag-Leffler Lévy processes (MLLP) and some extensions which are not available in a collective way in a single article. Our results generalize and complement the results available on Mittag-Leffler distribution and MLLP in several directions. Further, the asymptotic forms of the moments of the first-exit times of the TMLLP are also discussed. 相似文献

In a recent research, the quasi-likelihood estimation methodology was developed to estimate the regression effects in the Generalized BINMA(1) (GBINMA(1)) process. The method provides consistent parameter estimates but, in the intermediate computations, moment estimating equations were used to estimate the serial- and cross-correlation parameters. This procedure may not result optimal parameter estimates, in particular, for the regression effects. This paper provides an alternative simpler GBINMA(1) process based on multivariate thinning properties where the main effects are estimated via a robust generalized quasi-likelihood (GQL) estimation approach. The two techniques are compared through some simulation experiments. A real-life data application is studied. 相似文献

In this paper, a comparison between the life distribution of a new unit with that of a used unit in the increasing convex order is made leading to a new class of life distributions which we call “new better than used in convex ordering of second order”. This class includes as subclasses the NBU and the NBUC and is a subclass of the NBUCA class. Preservation properties under convolution, random maxima, mixing and formation of coherent structures are established. Stochastic comparisons of the excess lifetime when the inter-arrival times belong to the NBUC(2) class are developed. Some applications of Poisson shock models and a test of exponentiality against NBUC(2) alternative are presented. 相似文献

Viral videos offer contemporary activists a nimble, provocative tool with which to disseminate humanitarian messages. This article historicizes anti-trafficking video media that imagine a new potential with which to alter behavioral norms around cocoa and chocolate. The article engages theories and approaches to historical and contemporary modalities of naming and shaming, spanning three centuries to the present day. Videos are examined for style, format, and content, with the view to describing a ‘blood chocolate’ visual and textual metonymy. Recurring themes include transnational power, corporate responsibility, and the horrific scale of exploitation. But viral videos also appear deeply influenced by neoliberal economics that celebrate lawful enterprise and promote consumer-driven solutions to exploitative child labor. 相似文献

In this content analysis, researchers examine articles published from 2000 to 2015 in three family therapy journals, yielding a total of 948 empirical articles. The purpose is to provide an overview of the research being published, assess who is publishing, and investigate the current state of clinical effectiveness research in marriage and family therapy (MFT). Most first authors were affiliated with MFT programs and primarily included diversity and couples in their research. There was a significant increase of research on clinical process—though the number of clinical outcome studies held steady. There were no significant changes with regard to research funding. Implications support the use of innovative research methods to provide evidence of clinical effectiveness. 相似文献

This article introduces the concept of the interloper for examining classed and gendered dislocation. Focusing on academia, which we view as a classed and gendered field, we draw on Bourdieu and feminist standpoint theory to account for how we, as women of working‐class origin, have experienced ‘breaches' through which we have come to understand ourselves in classed and gendered terms. Coming from different cultural backgrounds, we also reflect on how understandings of class are context‐specific. We employ a duoethnographic method which emphasizes the value of subjective experiences for organizational and social analyses. The article shows how the concept of the interloper may shed light on the dynamic, relational character of constructions of class and gender; the maintenance work that is performed; and how a sense of permanent inbetweenness characterizes our ongoing movement between the fields of the family and academia. 相似文献
