The purpose of this study was to elucidate mechanisms involved in the intergenerational transmission of trauma-related distress. This study investigated whether betrayal trauma (BT; abuse by a person close to the victim) and specific parenting attitudes and behaviors among mothers with child abuse histories predicted internalizing and externalizing symptoms in their children. Mothers and children (ages 7–11) were recruited for a project on parenting and stress (N = 72). Maternal betrayal trauma predicted both internalizing (β = 0.33, p < .01) and externalizing symptoms (β = 0.25, p < .05) even when controlling for mothers’ trauma-related symptoms. Negative attitudes toward limit setting predicted externalizing symptoms (β = ?0.33, p < .05). Poorer communication (β = ?0.39, p < .05) but higher parenting satisfaction (β = 0.38, p < .01) predicted internalizing symptoms. These findings demonstrate the importance of assessing maternal trauma and parenting characteristics as part of interventions with symptomatic children.  相似文献

In the past two decades, the field of translation studies has increasingly focused on the role of ideology in literary translation and cross-cultural transfer. This paper presents findings from the close textual comparison of original works of Hebrew literature and their English translations published in the United States during the 1970s and 1980s. I specify translation strategies that have had ideological effects on the source texts, and demonstrate how historically or ethically charged subject matter was manipulated so as to subdue “problematic” aspects of the text for the (largely Jewish) target audience. The two major categories of manipulations had to do with the moral dimension of the portrayal of Israel and Israeli society, particularly in subject matter related to the Israeli–Palestinian conflict; and with the relationship between Israel and other nations, and between Israel and Diaspora Jews. As stressed by recent sociological studies of translation, the translations can be seen both as reflective of contemporary socio-political trends of thought, and as practices playing an unseen role in strengthening these trends.  相似文献

ObjectivesWe examined the association of multiple process, person, and context factors (Bronfenbrenner, 2005) with parents’ involvement (support and pressure) in sport. Specifically, we examined (a) the concordance among self, partner, and child reports of fathers and mothers for key study variables, and (b) prediction of parent support and pressure in youth sport by warmth and conflict in the parent–child relationship, parent positive and negative affect, and mastery and ego dimensions of the coach-created motivational climate.DesignCross-sectional survey.MethodSelf-reports of study variables were collected from athletes (ages 11–13 years) and parents from participating families (final N = 201). Multitrait-multimethod analysis was used to address the first study aim and multivariate multiple regression analysis for the second aim.ResultsValues for concordance among reporters were largely significant and in hypothesized directions, yet were of modest magnitude and suggested low reporter agreement (Cohen's κ range = −.07–.35). Multivariate relationships were significant and were of low to moderate magnitude (Rd range = .04–.22). Canonical loadings showed that warmth, positive affect, and mastery climate positively associate with support, whereas conflict, negative affect, and ego climate positively associate with pressure from fathers and mothers. Conflict and positive affect positively associated with support and pressure in some functions, suggesting complexity in interpretations of parent involvement.ConclusionFindings support the adaptive role of parent-child warmth, positive parent affect, and coach-created mastery motivational climate in youth sport; however, low concordance of reporter perceptions must be considered when pursuing family-related questions in sport.  相似文献

Negative information processing biases have been hypothesised to serve as precursors for the development of depression. The current study examined negative self-referent information processing and depressive symptoms in a community sample of adolescents (N = 291, Mage at baseline = 12.34 ± 0.61, 53% female, 47.4% African-American, 49.5% Caucasian and 3.1% Biracial). Participants completed a computerised self-referent encoding task (SRET) and a measure of depressive symptoms at baseline and completed an additional measure of depressive symptoms nine months later. Several negative information processing biases on the SRET were associated with concurrent depressive symptoms and predicted increases in depressive symptoms at follow-up. Findings partially support the hypothesis that negative information processing biases are associated with depressive symptoms in a nonclinical sample of adolescents, and provide preliminary evidence that these biases prospectively predict increases in depressive symptoms.  相似文献

Models of anxiety disorders posit that information processing biases towards threat may result from an imbalance between top-down attentional control processes and bottom-up attentional processes, such that anxiety could reduce the influence of the former and increase the influence of the latter. However, researchers have recently pointed to limitations of the top-down/bottom-up terminology and outlined the additional contribution of memory processes to attention guidance. The goal of this paper is to provide bridges between recent findings from cognitive psychology and anxiety disorders research. We first provide an integrative overview of the processes influencing the content of working memory, including the availability of attentional control, and the strengths of task goals, stimulus salience, selection history and long-term memory. We then illustrate the interest of this formulation to the study of information processing biases in anxiety disorders, with a specific focus on social anxiety.  相似文献

This article explores the impact of the economic crisis on the Orthodox Church of Greece (OCG). The first three parts of the article set the current stage by offering a short overview of the crisis and the response of the OCG through its charitable social welfare activities. The fourth part looks at church–state relations in Greece, covering more particularly its financial aspects. The fifth and final part discusses how the economic crisis has affected the OCG itself, including its own finances and governance, and sustainability and mission in the long term. Although the OCG provides social assistance to the Greek population during the economic crisis, it also finds itself very much affected by the same crisis. The economic crisis has forced the OCG to reduce its operating costs while at the same time continue its extensive social work. The crisis has also prompted public debates and questions about the finances of the OCG. This situation may gradually force either the Greek state or the OCG, or perhaps both, to rethink their relationship in the future.  相似文献

In-vehicle navigation systems (IVNS) have the potential to benefit older drivers, reducing stress associated with way-finding and providing on-trip support, especially in unfamiliar locations. However, existing IVNS present challenges to usability, resulting in lack of uptake and over-reliance on pre-trip planning.This paper presents research aimed at identifying features that make IVNS user-friendly and appropriate for older drivers. Studying navigational performance within a simulated driving environment, it focuses on the use of landmarks with route guidance information, and the most appropriate method of information provision (audio only, visual only or a combination of audio and visual). It also assesses potential gender differences that might arise with landmark-based navigational information.Solutions include use of appropriate roadside landmarks, and information delivered through a combination of audio and icon-based visual format. These features result in lower workload and fewer navigational errors. The audio/visual modality reduces the hazard of distraction by landmarks resulting in fewer visual glances and lower glance duration to the roadside compared to other modalities.Design and provision of IVNS tailored to older drivers’ needs can make a considerable contribution to maintaining individual mobility for longer.  相似文献

This article discusses the response of our ethics consultation service to an exceptional request by a patient to have his implantable cardioverter defibrillator (ICD) removed. Despite assurances that the device had saved his life on at least two occasions, and cautions that without it he would almost certainly suffer a potentially lethal cardiac event within 2 years, the patient would not be swayed. Although the patient was judged to be competent, our protracted consultation process lasted more than 8 months as we consulted, argued with, and otherwise cajoled him to change his mind, all to no avail. Justifying our at times aggressive paternalistic intervention helped us to reflect on the nature of autonomy and the dynamics of the legal, moral, and personal relationships in the clinical decision-making process.  相似文献
