We used observed parenting behaviors, along with genetic variants and haplotypes of the serotonin transporter gene (SLC6A4), as predictors of children's ego‐resiliency during early childhood (N = 153). The quality of mothers' parenting was observed at 18 months of age, and mothers' reports of ego‐resiliency were collected at six time points from 18 to 84 months. Genetic data were collected at 72 months. Observed parenting was positively associated with initial levels of children's ego‐resiliency. Furthermore, although individual genetic variants of the serotonin transporter gene (LPR, STin2) were not associated with ego‐resiliency, the S10 haplotype (that combines information from these two variants) was negatively associated with initial levels of ego‐resiliency. Both parenting and serotonin genetic variation uniquely predicted children's ego‐resiliency, suggesting an additive effect of genetic and parental factors.  相似文献

Depression is the most commonly diagnosed mental illness in the United States with relapse rates as high as 80–90% in some circumstances (Chen et al. in Res Soc Work Pract 16(5): 500–510, 2006; Mintz et al. in Arch Gen Psychiatry 49: 761–768, 1992; Teasdale et al. in J Consult Clin Psychol 68(4): 615–623, 2000). Cognitive therapy (CT) and psychopharmacology have been the mainstays of treatment for depression and relapse prevention, yet relapse remains a significant risk of this mental illness (DeRubeis et al. in Arch Gen Psychiatry 62: 409–416, 2005; Meyer and Scott in Behav Cogn Psychother 36: 685–693 2008; Rush et al. in Cognit Ther Res 1: 17–37, 1977). The literature review, case illustration and analysis examines the rationale for integrating mindfulness practice, and demonstrates the application of this practice in conjunction with cognitive therapy to reduce the risk of relapse in Major Depression.  相似文献

Approximately 3 million teens are diagnosed with a sexually transmitted disease (STD) annually; STDs rates for American Indian young adults are among the highest of any racial/ethnic group. An important risk factor for STDs is early initiation of sex. In this study, we examined risk for early initiation with 474 American Indian youth ages 14–18, using 11 risk factors from three developmentally important microsystems (family, school, peers) along with several individual characteristics; a cumulative risk index was also calculated. Discrete‐time survival analyses showed that predictors of early initiation differed by gender. For young men, younger initiation of sex was predicted by lower grades, liking school less, having peers with less prosocial attitudes, a greater likelihood of having used alcohol or drugs at first sex, and having higher sensation‐seeking. For young women, earlier initiation was related to having mothers who had their first child at an early age and who had less formal education, to having parents who had divorced, dropping out of high school, using alcohol/drugs at first sex, and higher sensation‐seeking. Higher cumulative risk was associated with elevated risk of sexual initiation, although the degree of added risk varied with age for women. Cumulative risk deserves broader attention in understanding the early initiation of sexual intercourse.  相似文献

Mothers’ mental state language in conversation with their preschool children, and children's preschool attachment security were examined for their effects on children's mental state language and expressions of emotional understanding in their conversation. Children discussed an emotionally salient event with their mothers and then relayed the event to a stranger. Compared to mothers of insecurely attached children, mothers of securely attached children used more mental state language and had children who used more mental state language with both mother and stranger, and who expressed more emotional understanding in the mother–child conversation. Maternal mental state language and attachment security made shared contributions to children's mental state language with their mothers. Maternal mental state language accounted for the effects of attachment security on children's expressions of emotional understanding in the mother–child conversation. Mothers’ mental state language to their children may enhance secure attachment and foster children's understanding of mental states in self and others.  相似文献

In this paper, we use racial data from Census 2000, available for the first time in 50 years, to examine the links among race, socioeconomic status, and residential location on the island of Puerto Rico. Puerto Ricans overwhelmingly chose white as their race, and they chose only one race, not a combination of races that would seem more in keeping with the ideology of mestizaje. Overall, segregation by race is modest compared with residential segregation in the United States. In keeping with the Puerto Rican claim that class is more important than race, we find that segregation by race is generally lower than segregation between the lowest and highest income categories in all metro areas, but that the results for education and occupational status differ by metropolitan area. In San Juan-Bayamón, the most diverse metropolitan area on the island, we find that as percent black increases, neighborhood socioeconomic status decreases, though the changes are not that stark, except in Loiza, a community of black Puerto Ricans and in some Dominican neighborhoods, though there are relatively few of these neighborhoods.  相似文献

This paper examines 3,144 comments in a March 2012 Huffington Post forum about an online Belvedere vodka advertisement that was widely interpreted to depict sexualized violence. The study applies critical textual analysis, relating discourse to context to illuminate recurring themes and clues to the strategies and resources influencing how comments were constructed. Four major recurring themes emerge from within a wide range of topics: (1) speculations on advertising strategy; (2) contested perceptions of sexual assault; (3) links between gender politics and party politics; and (4) media literacy lessons. Cutting across themes is an apparent awareness of context, including the site’s reward system, its predominantly left-leaning politics, and the potential consequences of participant commentary being exploited by Belvedere to increase brand recognition. Comments often invoke personal or professional authority by articulating qualifications presumed relevant to the advertisement’s deconstruction. The study suggests that forum participants can be understood as members of productive communities, who construct responses structured by shared contextual constraints and/or relevant common experience. The study also suggests that online forum participation offers mixed prospects for lay critics of media misogyny in that their commentary vies for attention alongside missives calculated to be provocative.  相似文献

A bibliographic study on a multidisciplinary subject, such as occupational stress, requires a multidatabase query facility. Given this, we searched eight databases belonging to different fields (medicine, psychology, etc.) and from different countries. Thus, more than 26000 references on occupational stress were gathered. A bibliographic corpus of this sort is unusable because of the heterogeneous format of the records and the number of duplicate entries. Considering the limitations of commercial programs, we have developed a system, called WebStress, for reformatting the data and removing duplicates. The huge number of references and the research needs of updating and searching have necessitated the addition of several other functions to WebStress. Therefore WebStress comprises a web interface that makes it possible to search the corpus with advanced features (using clustering, a specialized thesaurus on stress and Boolean queries). In addition to the usual bibliographic queries on a specific database such as Medline, WebStress provides bibliometric analysis of the corpus, which might contribute to a detailed analysis on occupational stress in order to highlight the networks of researchers and to find the main topics studied in this area. WebStress is not yet available to researchers in general. It is being further developed, and also permission needs to be obtained from the eight commercial bibliographic databases that it consults.  相似文献

Abstract

Social bookmarking, repositories, networking, and other Web 2.0 technologies have the capacity to engage enormous numbers of ordinary people in networking, sharing, and working with digital resources. The Faculty of Education at The University of Hong Kong has been pioneering new educational applications. Through grants from the University we have developed a social bookmarking and repository system based on Web 2.0 ideas. RISAL—Repository of Interactive Social Assets for Learning has an unrealized potential to support teaching and learning at the University level. It is designed to facilitate and encourage sharing and collaboration of teachers and students with similar interests or learning foci across levels and programs. This form of learning support builds on and encourages the Web 2.0 culture of social networking and contribution of the individual to the community. In addition, the system is designed to incorporate compliance with Hong Kong's Copyright Ordinance (Creative Commons). The authors discuss the RISAL and describe its features and benefits that this system can offer to teaching and learning.  相似文献
