War and social transition in Croatia have increased unemployment and rates of substance abuse. A decrease in prevention programs places adolescents at an increased risk. Data collected from the 2002 Split Youth Behavior Risk Survey (YRBS) showed that adolescents are at risk for alcohol use and related problems. Thus, there is a need to strengthen primary and secondary prevention activities to empower adolescents and counteract negative societal change. A public health partnership between the University of Medicine and Dentistry of New Jersey-School of Public Health (UMDNJ-SPH) and Split, Croatia was formed in 2001. Adolescent alcohol prevention was identified as our focus and Project Northland, a model U.S. program, was selected. A strong network of NGOs and government officials support the project. Qualitative evaluation showed strong parent, teacher, and student satisfaction. Preliminary analysis shows a heightened awareness on the part of students that will likely contribute to the overall success of the program.  相似文献

Research shows that participation in employment contributes to life satisfaction for persons with disabilities [18]. Title I of the Americans with Disabilities Act (ADA) sought to prohibit discrimination against persons with disabilities in the workplace, however, the ADA's effectiveness remains controversial. This research utilizes data from the disability supplement of the 2000 Behavioral Risk Factor Surveillance System to examine the impact of disability status on predicting employment status and income. Confounding variables such as gender, age, educational level, race and marital/parental status are examined regarding their influence on results. Results from analysis utilizing zero-order correlation, linear and logistic regression analysis techniques revealed that disability status has a significant predictive effect on inability to work. Furthermore, results continue to show that despite legislation, the higher the level of disability, the lower the employment status (those employed for wages) and income. Finally, disability status, coupled with being female or decreased educational level, consistently shows significance in predicting lower employment status and income than men or non-minorities with disabilities. Future research opportunities and policy implications are discussed with regard to the results presented.  相似文献

Alcohol use among college students is linked to an increased likelihood of engaging in risky sexual behaviors, including casual sex and unprotected sex. These behaviors increase college students' risks for negative social and health-related consequences. This study examined the relationship between drinking behaviors and protective behavioral strategies (PBS), expectancies and perceptions of sexual risk, and actual alcohol-related sexual behaviors and consequences. Sexually active college students completed Web-based self-report measures of drinking behaviors and use of PBS, alcohol expectancies and perceptions of risk, and sexual behaviors and related consequences (n = 524; 57.1% women). Findings indicated that PBS were related to lower expectancies of sexual risk and sexual disinhibition, and among lighter drinkers, lower expectancies of sexual enhancement from alcohol. PBS were also related to decreased perceptions of sexual-related risks, some alcohol-related sexual behaviors, including number of drinks before/during sex, and number of sexual consequences, but were not related to abstaining during sex, frequency of alcohol-related sexual behaviors, or general condom use. These findings demonstrate a disconnect between perceived and actual risks among college students, such that decreased perceptions of risk may not be associated with protective behaviors. Prevention and intervention implications are discussed.  相似文献

Eating disorders and body dissatisfaction among undergraduate men are less documented and researched than are eating disorders and body dissatisfaction among undergraduate women. OBJECTIVE AND PARTICIPANTS: In this study, the authors examined these issues in undergraduate men to identify similarities and differences between this population and undergraduate women. METHODS: In a random sample of undergraduates, the authors categorized respondents by gender and by presence or absence of an eating disorder. The authors compared undergraduate men with an eating disorder with (1) undergraduate women with an eating disorder and (2) undergraduate men without an eating disorder. RESULTS: The patterns of responses suggest that undergraduate men with an eating disorder are preoccupied with body shape and tone but not necessarily with losing weight. CONCLUSIONS: The authors discuss implications for future prevention as well as clinical and research efforts based on male symptoms within the diagnostic category of bulimia nervosa and eating disorder, not otherwise specified.  相似文献

This paper examines the impact of new information and communications technologies (ICTs) on levels of intra-party democracy in the UK in light of recent claims of increasing centralization of power and marginalization of members within West European political parties. Specifically, it examines whether parties adoption of the internet, in the shape of an internal computer communication system (ICCS) and internal party groups' use of the World Wide Web (WWW), is promoting intra-party democracy in two areas: (1) the vertical distribution of power between members and elites; (2) the spatial concentration of power between intra-party groupings and central party elites. The findings show that while many parties have made use of the internet for internal communication there is no concerted effort being made by parties to harness its potential to promote members input into decision-making and elite accountability.  相似文献

Contemporary theory and culture can lead a therapist to view a client’s positive feelings towards parents as defensive idealization, while negative or hostile feelings may be seen as “deeper” and more important. This article suggests that both idealization of and critical feelings about parents can serve as defenses against other painful emotions and both are developmentally necessary. Contemporary neurobiological and attachment research indicate that “talk therapy” helps individuals manage emotions. This work can be derailed if anger is privileged over idealization. Clinical examples illustrate these ideas and show how unpacking both critical and overly positive attitudes can encourage development. Clients increase their capacity to tolerate a wider range of feelings, maintain a consistent and cohesive sense of self, and build meaningful relationships. Therapists’ countertransferential identification with clients’ parent-blaming and a not uncommon desire to reduce complex and confusing experiences to a more manageable subset of emotions are also addressed.  相似文献

Product returns present one of the biggest operational challenges in the world of Internet retailing due to the sheer volume and cost of processing returns. But returns also represent an often‐missed opportunity to manage customer relationships and build customer loyalty to the retailer. Based upon data from a survey of 464 customers of five different Internet retailers, this article explores how firms' returns management systems affect loyalty intentions. We draw upon extant literature in the fields of Internet retailing, service quality, supply chain management, and customer satisfaction/loyalty to develop a model and a set of hypotheses relating ten latent variables in the service returns offering area. Our resulting structural equation model provides evidence of the impact of the returns management system upon customer loyalty intentions. The model also identifies effects on loyalty intentions arising from customers' satisfaction with, and perceptions of, the value of the returns service offered. These findings will help inform managers' choices regarding investment in the returns management system as an element of service quality improvement and a potential means of improved profitability. In addition, this study's empirical exploration and testing of a returns management model in the Internet retailing environment is a contribution to the currently underrepresented body of academic literature linking marketing and supply chain management in the context of end consumers.  相似文献

Abstract

Objective: The study investigated the role of mother–daughter communication and race in college women’s decisions to pursue sexual health screening services. Participants: Participants were 301 college women who primarily identified as White and Asian American (Mage = 19?years). Methods: Participants completed an online survey that assessed mother–daughter communication about sex and responded to items pertaining to pursuing sexual health screening services. Results: Maternal communication predicted daughters’ screening behaviors and sexual anxiety mediated the negative association between conservative communication from mothers and screening behaviors. Asian American college women were less likely than White college women to report that they received frequent and open communication about sex from their mothers and reported higher levels of sexual anxiety. Conclusions: Mothers should be aware of the implications their communication patterns may have on their daughters’ sexual and reproductive health, and college women’s sexual anxiety should be addressed in order to increase utilization of screening services.  相似文献

When considering how to allocate scarce resources for the development of public infrastructure, many countries have a tendency to neglect maintenance in favor of new infrastructure investment projects. We examine the role of maintenance expenditures on output and on the distribution of wealth in a heterogeneous agents model. In our model, maintenance affects the quality of existing infrastructure and thus the flow of services derived from it. Furthermore, maintenance expenditures also affect the depreciation rates of both public infrastructure and private capital. We calibrate our model to Mexico and consider several policies that increase the flow of resources to infrastructure and find that a policy that allocates all additional resources to new investment is dominated by policies that allocate at least some of the additional resources to maintenance. Specifically, focusing all additional resources on maintenance is shown to generate the largest reduction in inequality, while a more balanced policy that increases both investment and maintenance maximizes output growth.
