This paper empirically analyzes the joint impact of democracy and press freedom on corruption. Based in the theoretical literature, we argue that both institutional features are complements rather than substitutes in controlling corruption. Our regressions are based on a cross section of 170 countries covering the period from 2005 to 2010 as well as on panel evidence for 175 countries from 1996 to 2010. The results show that democratic elections only work in controlling corruption, if there is a certain degree of press freedom in a country, vice versa. Our policy implication is that democratic reforms are more effective, if they are accompanied by institutional reforms strengthening the monitoring of politicians. 相似文献

Quality of Web-based Information on Pathological Gambling 总被引:1,自引:0,他引:1
Khazaal Y Chatton A Cochand S Jermann F Osiek C Bondolfi G Zullino D 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》2008,24(3):357-366
The present study aims to evaluate the quality of web-based information on gambling and to investigate potential content quality
indicators. The following key words: gambling, pathological gambling, excessive gambling, gambling problem and gambling addiction
were entered into two popular search engines: Google and Yahoo. Websites were assessed with a standardized proforma designed
to rate sites on the basis of “accountability”, “presentation”, “interactivity”, “readability” and “content quality”. “Health
on the Net” (HON) quality label, and DISCERN scale scores aiding people without content expertise to assess quality of written
health publication were used to verify their efficiency as quality indicators. Of the 200 links identified, 75 websites were
included. The results of the study indicate low scores on each of the measures. A composite global score appeared as a good
content quality indicator. While gambling-related education websites for patients are common, their global quality is poor.
There is a need for useful evidence-based information about gambling on the web. As the phenomenon has greatly increased,
it could be relevant for Internet sites to improve their content by using global score as a quality indicator. 相似文献

This research note utilizes German matched employer–employee data to investigate the relationship between mobility and relative wage positions within establishments for workers without university degrees. The main innovation involves the examination of non‐linear effects, because previous literature mainly analyses mean linear effects. Our random‐effects probit estimates of mobility suggest a non‐linear U‐shaped effect with respect to relative standing. This is plausible because workers in low relative wage positions might quit because of their low status and those in high relative wage positions because of their low career advancement opportunities. Consideration of non‐linearities, thus, is a major improvement for the analysis of the effects of relative wage positions. 相似文献

There is strong public opposition to increased immigration throughout Europe. Given the modest economic impacts of immigration estimated in most studies, the depth of anti‐immigrant sentiment is puzzling. Immigration, however, does not just affect wages and taxes. It also changes the composition of the local population, threatening the compositional amenities that natives derive from their neighborhoods, schools, and workplaces. In this paper we use a simple latent‐factor model, combined with data for 21 countries from the 2002 European Social Survey (ESS), to measure the relative importance of economic and compositional concerns in driving opinions about immigration policy. The ESS included a unique battery of questions on the labor market and social impacts of immigration, as well as on the desirability of increasing or reducing immigrant inflows. We find that compositional concerns are 2–5 times more important in explaining variation in individual attitudes toward immigration policy than concerns over wages and taxes. Likewise, most of the difference in opinion between more‐ and less‐educated respondents is attributable to heightened compositional concerns among people with lower education. 相似文献

The accounting for pension obligations is based upon numerous parameters, whose future developments must be forecasted for valuation purposes. If the actual realizations of theses parameters deviate from their original estimations there are generated so-called actuarial gains and losses. IAS 19 provides three alternative accounting treatments with respect to these actuarial gains and losses. In particular the equity and the corridor approach, both frequently used in practice, implicitly assume that the actuarial gains and losses offset each other in the long run. However different studies have demonstrated by using the Monte-Carlo-Simulation-technique that this long-term offset is not assured. But those studies do not propose a rationale for the observed generation of systematic actuarial gains and losses. The present paper provides an analytic rationale for the systematic appearance of actuarial gains and losses and comes to the following conclusion: The long-term offset of actuarial gains and losses is assured only if the parameters that must be estimated for valuation purposes are independent. However if there is an interdependence between those parameters, which seems to be a sound assumption in reality, the offset of actuarial gains and losses is not given. In case of a positive correlation actuarial losses are generated on a systematic basis, whereas a negative correlation results in actuarial gains. 相似文献

Social Networks,Social Cohesion,and Later-Life Health 总被引:1,自引:0,他引:1
Our study contributes to the literature acknowledging the joint role of social networks and social cohesion in shaping individual’s health, focusing on the older population aged 50 and over. Exploiting rich ego-centered social network data from the Survey of Health, Ageing and Retirement in Europe and following the conceptual model of social integration and health proposed by Berkman et al. (Soc Sci Med 51:843–857. doi:10.1016/S0277-9536(00)00065-4, 2000), we estimate multilevel models of self-reported and observer-measured later-life health outcomes. These models simultaneously account for (a) characteristics of 39,551 respondents’ personal social networks and (b) a measure of social cohesion—namely, participation in social organizations—across 57 Continental European regions, clustered in 14 countries. We find significant associations between individuals’ health and various social network characteristics (size, support, quality) as well as social cohesion. Moreover, cross-level interaction effects suggest that the social-network-health nexus is contextually bound. We conclude with a discussion of limitations and perspectives for future research. 相似文献

Epidemiological studies have found that young men who have sex with men (YMSM) represent the majority of young people infected with HIV annually in the United States. Further, they are one of the few risk groups to show an increase in the rate of infections in recent years. In addition to these disparities in prevalence and infection rates, there is an inequity in prevention and intervention research on this population. The purpose of this article is to review the existing YMSM literature on HIV epidemiology, correlates of risk, and intervention research. The article concludes that promising future directions for basic research include a focus on multiple clustering health issues, processes that promote resiliency, the role of family influences, and the development of parsimonious models of risk. In terms of intervention research, the article suggests that promising future directions include Internet-based intervention delivery, integration of biomedical and behavioral approaches, and interventions that go beyond the individual level to address partnership, structural, community, and network factors. 相似文献

This study applies multilevel social network analytic techniques to examine processes of homophilic selection and social influence related to alcohol use among friends in early adolescence. Participants included 3,041 Dutch youth (M age =12 years, 49% female) from 120 classrooms in 14 schools. Three waves with 3‐month intervals of friendship nomination data and self‐reports of drinking behavior were collected. Results revealed that within classrooms, friendship nominations tended to be reciprocated and dyadic friendships tended to be embedded within cohesive subgroups (e.g., cliques). Students tended to nominate friends who were the same sex, from a similar ethnic background, and who they previously knew from primary school. Selection processes turned out to play a more significant role than social influence processes in predicting similarity between early adolescent friends' alcohol use. Although friendship dynamics and individual drinking trajectories substantially differed between classrooms, the effects of homophilic selection and social influence did not. 相似文献
