This paper presents results from the study of gambling behaviors in a representative sample of Cypriot high-school students. The aim of the study was to ascertain epidemiology of adolescent online gambling in Cyprus and possible correlates. The sample consisted of 2,684 students (48.5 % boys, 51.5 % girls) from the first grades of junior (Gymnasium) and senior (Lyceum) high school. Our results indicate that gamblers presented with lower school achievement and related expectations while scoring consistently higher on measures of Internet addiction, parental bonding and psychopathology. Discriminant analysis revealed two profiles which explained the most variance in gambling behavior; the first profile that corresponded to more explained variance was the student with higher psychopathology, less prosocial behavior, higher Internet addiction score with higher frequencies of online activities and moderate levels of truancy and lower expectation of school achievement. The second profile was that of a student who reported less psychopathology, more prosocial behavior, less involvement with the Internet in general but skipped classes more and his prospects on finishing high school were even slimmer. These results will be utilized in the design of a comprehensive prevention program in an effort to combat online addictive behaviors.  相似文献

The proliferation of gambling opportunities in Canada, coupled with an aging population, has led to an increased prevalence of gambling among older adults. Encouraged by this trend, gambling industries have modified their activities to attract and market to this group. Yet, older adults are not a homogeneous group. The life experiences, values, and attitudes shared by generations make a cohort-specific analysis of gambling among older adults a worthwhile pursuit. Drawing from the Dualistic Model of Passion (Vallerand et al. in J Pers Soc Psychol 85(4):756–767, 2003), we discuss the role of passion in shaping gambling behaviours, and the implications of a harmonious or obsessive passion on the benefits and risks to two distinct generations of older adults. Based on their generational attributes, we posit that members of the Silent Generation (those born between 1925 and 1942) stand to gain more from the benefits of recreational gambling, but also stand lose more from problem gambling, than their children’s generation, the Baby Boomers (those born between 1942 and 1964). Preventative strategies to assist problem gambling seniors, along with recommendations for further research, are discussed.  相似文献

Urban plant biodiversity is influenced by both the physical environment and attitudes and preferences of urban residents for specific plant types. Urban residents are assumed to be disconnected from their immediate environment, and cultural and societal factors have been emphasized over environmental factors in studies of landscaping choices. However, we postulate that local climatic and environmental factors can also affect preferences for plant attributes. Therefore, spatial and temporal patterns in urban tree biodiversity may be driven not only by the direct effect of environmental variables on plant function, but also by the effect of environmental variables on attitudes toward trees and associated choices about which types of trees to plant. Here, we tested the relative effects of socio-economic and local environmental factors on preferences toward tree attributes in five counties in southern California in and surrounding Los Angeles, based on 1,029 household surveys. We found that local environmental factors have as strong an effect on preferences for tree attributes as socio-economic factors. Specifically, people located in hotter climates (average maximum temperature 25.1 °C) were more likely to value shade trees than those located in cooler regions (23.1 °C). Additionally, people located in desert areas were less likely to consider trees to be important in their city compared with people located in naturally forested areas. Overall, our research demonstrates the inherent connections between local environmental factors and perceptions of nature, even in large modern cities. Accounting for these factors can contribute to the growing interest in understanding patterns of urban biodiversity.  相似文献

Inconsistencies in comparisons of older parents’ well-being with that of older, childless adults may be resolved by considering the separate effects of sons and daughters on parents. The hypothesis was that older parents of only daughters have greater life satisfaction, more satisfying relations with their children, more intimate family relations, and greater social support satisfaction compared to older childless adults and parents of only sons. Childless older adults were predicted to have more intimate friends. The effect of having both sons and daughters was also explored. Longitudinal results indicated parents had greater life satisfaction than childless adults, and parents of daughters were more satisfied with relations with their children than parents of only sons. Childless adults had more relations with friends and fewer family intimate relations. Neither social support satisfaction or affect varied across groups. The findings are related to gender socialization, social support, and normative expectations.  相似文献

This study tests for causality from exercise and physical activity to life satisfaction (LS) by applying an instrumental variable approach with the respondents’ perceived benefits of exercise participation as instruments. Using data across 25 countries from the Eurobarometer survey, our results confirm the positive association between exercise and LS. In terms of causality, the results indicate that being active increases LS for both gender, though more for men than women. One main reason for this relationship is that exercise is perceived as being pleasurable, something that policy-makers should keep in mind when designing programmes to get us off the sofa.  相似文献

I derive alternative measures of maximum willingness to pay (WTP) and value of statistical life (VSL) for selfish members of two-person households who bargain efficiently over consumption of individual and household goods. There is then no systematic bias in letting one member conduct the valuation on behalf of the household. Public-good VSL may exceed private-good VSL when each member attaches (selfish) preferences to survival of the spouse, and to any income from a surviving spouse in period 2. When period 2 is a retirement period and household members’ incomes are fixed, interview surveys tend to overvalue VSL due to ignored negative effects of own survival on private of public pension budgets.JEL Classification: I12, G22, J17  相似文献

Consider a firm as an organization that needs to efficiently coordinate several specialized departments in an uncertain environment. Decision making involves collective planning sessions and decentralized operational processes. In this setting this paper explores the role of economic modeling through an experimental game. Results support the idea that economic modeling favors higher performance. Economic modeling facilitates the emergence of common knowledge and the decomposition of a group decision problem into individual decision problems that are meaningfully interrelated. This paper was presented at the Porquerolles Summer School on Cognitive Sciences, September 2001.  相似文献

In an era during which affirmative action in education is in jeopardy, it is important to understand how the ideologies of high-status ethnic group members maintain (or reduce) social inequality. We examine the extent to which the relationship between egalitarianism and prejudice among European American and Asian American adolescents can be explained by outgroup orientation (i.e., how much one values interacting with members of other ethnic groups) and strength of identification with one's ethnic group. Using structural equation modeling, we tested whether these two variables mediate the relationship between egalitarianism and intergroup prejudice. Results revealed that outgroup orientation was a mediator, but ethnic identity was not. Implications for mutual acculturation theory, prejudice-reduction programs, and affirmative action in education are discussed.  相似文献

In this article the hedonic regression technique is used to estimate the value of traffic safety, using information from the Swedish market for automobiles. The results from the study show that the market price of an automobile is negatively correlated with its inherent risk level, i.e. Swedish car consumers pay a safety premium for safer cars. In comparison to previous Swedish stated-preference studies, this study reveals a lower willingness to pay for additional car safety, which might be a result of the interaction between government interventions and individual self-insurance and self-protection.JEL Classification: C51, D61, J28  相似文献
