Abstract

Objective: The etiology of body dissatisfaction and its correlates (eg, disordered eating) among ethnic minorities is generally unknown. The purpose of this study was to replicate the tripartite model of influence in an Asian American college female sample in order to examine this relationship. Participants: Participants were 80 undergraduate Asian American females between the ages of 18 and 25. Methods: Participants completed a survey that included the Tripartite Influence Scale, Body Parts Satisfaction Scale, and Sociocultural Attitudes towards Appearance Questionnaire–3. Results: Mediation analyses indicated that thin-ideal internalization fully mediated the relationship between media influence and body dissatisfaction and partially mediated the relationship between peer influence and body dissatisfaction. Family influence did not significantly predict body dissatisfaction. Conclusions: Asian American college females experience body dissatisfaction through mechanisms that have not been examined in detail. These factors must be considered when creating targeted health promotion strategies and developing best practices for eating disorder assessment and treatment protocols at university health centers.  相似文献

It is widely accepted that the relationship between lightning wildfire occurrence and its influencing factors vary depending on the spatial scale of analysis, making the development of models at the regional scale advisable. In this study, we analyze the effects of different biophysical variables and lightning characteristics on lightning-caused forest wildfires in Castilla y León region (Central Spain). The presence/absence of at least one lightning-caused fire in any 4 × 4-km grid cell was used as a dependent variable and vegetation type and structure, terrain, climate, and lightning characteristics were used as possible covariates. Five prediction methods were compared: a generalized linear model (GLM), a random forest model (RFM), a generalized additive model (GAM), a GAM that includes a spatial trend function (GAMs) and a spatial autoregressive model (AUREG). A GAMs with just one covariate, apart from longitude and latitude for each observation included as a combined effect, was considered the most appropriate model in terms of both predictive ability and simplicity. According to our results, the probability of a forest being affected by a lightning-caused fire is positively and nonlinearly associated with the percentage of coniferous woodlands in the landscape, suggesting that occurrence is more closely associated with vegetation type than with topography, climate, or lightning characteristics. The selected GAMs is intended to inform the Regional Government of Castilla y León (the fire and fuel agency in the region) regarding identification of areas at greatest risk so it can design long-term forest fuel and fire management strategies.  相似文献

Abstract

Bullying presents a significant social distress for students, families and schools. Concerned practitioners and researchers are invested in developing interventions to decrease the frequency and negative impact of bullying. To do so, however, understanding the cast of characters in the bullying drama is critical. This paper reviews selected research on characteristics of bullies, victims and bystanders from a variety of theoretical and methodological approaches. The implications of these characteristics for effective interventions is considered. The role of socio-economic factors is presented, and their relevance for communities and policy makers discussed.  相似文献

This paper seeks mainly to contribute to the debate on how the relative degree of development of a country should be measured by proposing an indicator to build on the valuable starting point provided by the Human Development Index (HDI). The indicator proposed is called the “Composite, Dynamic Human Development Index”. It incorporates in a simple way additional points which are significant for the current concept of human development and provides a dynamic factor that distinguishes between countries on the basis of achievements attained. It helps ensure that the static average data on which the HDI is based does not conceal wide-ranging economic, social and political differences within countries, lack of sustainability in current levels of development or effective development strategies drawn up by governments.  相似文献

ABSTRACT

Marijuana use among Native American (NA) adolescents continues to be an ongoing concern and is often cited as the most critical health issue facing this population. Despite this recognition, few studies have examined the roles played by parental monitoring and school relationships among NA youth. This cross-sectional study used secondary data from the 2010 National Survey in Drug Use and Health to examine the combined influence of parental, peer, and school indicators on marijuana use among NA adolescents aged 12 to 17 years old (N = 287). The results of structural equation modeling suggest that peer factors and parental monitoring were significantly associated with marijuana use. In fact, the peer network was the most influential predictor. However, a significant relationship was not found between school relationships and marijuana use. Given the insignificance of school relationships, further research should examine the influence of peer interactions on marijuana use and the development of family-based prevention and intervention programs.  相似文献

Although the number of older workers in the U.S. is increasing, there is a gap in knowledge on whether or not they actually enjoy working. This study, based on a conceptual framework focusing on job resources and demands, explored likely workplace determinants of work enjoyment among older workers aged 50 or over. Using the 2012 wave of the Health and Retirement Study, a partial proportional odds model was used to detect determinants of work enjoyment. Results showed that higher levels of work enjoyment were significantly and negatively associated with the level of perceived retirement pressure and promotion preference for younger workers, and positively associated with moving to less demanding positions. Self-employment showed a noticeable enhancement of work enjoyment. This study highlights the significance of flexible work options and age discrimination in the workplace in understanding work enjoyment later in life.  相似文献

Abstract

This study analyses the relationships of certain sociodemographic, organizational, and personality variables with psychiatric sick leave taken by Spanish secondary school teachers. The sample comprised 200 teachers (84 men and 116 women) divided into two groups. The first group was composed of 100 teachers who had suffered from psychiatric disorders requiring sick leave. The second was a matched control group composed of 100 teachers with no history of psychiatric disorders. Both groups shared the same organizational variables (same centre, town, number of students, etc). Logistic regression analysis was conducted to determine any relationships and the risk and protection factors for psychiatric sick leave. It is concluded that the most significant variables related to psychiatric sick leave included competitiveness and hostility, as defined by Type A Behaviour Pattern, emotional exhaustion as a factor of burnout, and job dissatisfaction.  相似文献
