This study reports the findings from a national survey on gambling behaviour among Danish primary school children. A questionnaire was administered to 2,223 primary school students ranging in age from 11 to 17 years. The questionnaire contained a gambling screen (SOGS‐RA) and items that measure gambling behaviour, social network and cognitive perceptions. The prevalence of problem gambling was 1.29 per cent, while 4.5 per cent were categorised as at‐risk gamblers. The three most frequently reported reasons for gambling were to win money, to have fun and to socialise with family and friends. It is suggested that gambling may be linked to a masculine universe and that at‐risk gambling behaviour patterns may be part of a normal adolescent life in which gambling serves recreational or leisure purposes. Implications for further research and preventive measures are discussed.  相似文献

Feminist scholars the world over are increasingly aware of the importance of analyzing popular discourse, especially regarding women’s involvement in proscribed violence. Yet few have looked at Middle Eastern organizations, and fewer still at the Mojahedin-e Khalq Iran (MEK), a longstanding resistance group whose all-female leadership and sizeable female membership present a compelling challenge to prevailing gender norms. How do popular media portray female MEK resistors and what might these representations signify for our gendered conceptions of violence? In examining the MEK’s female leadership, this article undertakes a close reading of western and Iranian news coverage in an attempt to analyze the degree to which these women are painted as willful political agents or, as is often assumed, irrational actors incapable of autonomous political participation. Following Sjoberg and Gentry, I develop four cognitive frames to describe female resistors, while also challenging the media’s victimizing and sexualizing gaze. I thus problematize these women’s portrayals as “maniacal slaves,” and explain how such gendered rhetoric operates to preclude the notion that members of the MEK might practice legitimate political resistance worthy of analysis or understanding.  相似文献

Children in low-income neighborhoods tend to be disproportionately exposed to environmental toxicants. This is cause for concern because exposure to environmental toxicants negatively affects health, which can impair academic success. To date, it is unknown if associations between air toxics and academic performance found in previous school-level studies persist when studying individual children. In pairing the National Air Toxics Assessment risk estimates for respiratory and diesel particulate matter risk disaggregated by source, with individual-level data collected through a mail survey, this paper examines the effects of exposure to residential environmental toxics on academic performance for individual children for the first time and adjusts for school-level effects using generalized estimating equations. We find that higher levels of residential air toxics, especially those from non-road mobile sources, are statistically significantly associated with lower grade point averages among fourth- and fifth-grade school children in El Paso (Texas, USA).  相似文献

Abstract

Objective: To conduct a confirmatory factor analysis on the 17-item Sexual Health Survey (SHS), a comprehensive instrument designed to be used with college students. Participants: College students (N = 515) aged 18 to 26 years enrolled at a Midwest public university October 2009. Methods: Confirmatory factor analysis with maximum likelihood estimation was performed to test the stability of the constructs. Results: All factor loadings were significant (p < .001), ranging from .55 to .99 (standardized). The range of squared multiple correlations of items was .31 to .98, and the intercorrelations among the 5 factors were from ?.03 to .52. These small to moderate levels of intercorrelation support discriminant validity of 5 constructs. Conclusions: This study supports the 5-factor version of the 17-item SHS as a viable scale that can measure sexual health overall and 5 distinct areas. College health professionals should consider use of this scale for assessment purposes and evaluation of programmatic efforts.  相似文献

In today’s competitive context, the paradigm of sustainable development is becoming more and more significant, also in warehousing. Managers are progressively considering not only purely economic aspects but also environmental concerns. Despite such consciousness, the selection of automated warehousing solutions has been mainly based on operational and economic performance in both practice and theory so far, whereas energy consumption and environmental performance have not been adequately taken into account. To fill this lack, a model is proposed to evaluate the energy consumption and environmental impact of automated warehousing solutions. The model has been used to investigate whether and how the selection of automated solutions changes depending on the dimensions involved in the analysis (i.e. only economic, only environmental or both). The analysis has been performed considering autonomous vehicle storage and retrieval systems (AVS/RSs) and its natural alternative, i.e. automated storage and retrieval systems (AS/RSs). Results confirm the importance of considering both dimensions in the assessment of automated warehouses, as depending on the scenario, the technology selection shifts from AS/RS to AVS/RS when considering not only the economic but also the environmental impact. Additionally, this study provides new insights on the suitability areas of AVS/RSs.  相似文献

Using nanotechnology as a case study, this article explores (1) how people's perceptions of benefits and risks are related to their approval of nanotechnology, (2) which information‐processing factors contribute to public risk/benefit perceptions, and (3) whether individuals’ predispositions (i.e., deference to scientific authority and ideology) may moderate the relationship between cognitive processing and risk perceptions of the technology. Results indicate that benefit perceptions positively affect public support for nanotechnology; perceptions of risk tend to be more influenced by systematic processing than by heuristic cues, whereas both heuristic and systematic processing influence benefit perceptions. People who are more liberal‐minded tend to be more affected by systematic processing when thinking about the benefits of nanotechnology than those who are more conservative. Compared to less deferent individuals, those who are more deferent to scientific authority tend to be less influenced by systematic processing when making judgments about the benefits and risks of nanotechnology. Implications are discussed.  相似文献
