The damaged goods hypothesis posits that female performers in the adult entertainment industry have higher rates of childhood sexual abuse (CSA), psychological problems, and drug use compared to the typical woman. The present study compared the self-reports of 177 porn actresses to a sample of women matched on age, ethnicity, and marital status. Comparisons were conducted on sexual behaviors and attitudes, self-esteem, quality of life, and drug use. Porn actresses were more likely to identify as bisexual, first had sex at an earlier age, had more sexual partners, were more concerned about contracting a sexually transmitted disease (STD), and enjoyed sex more than the matched sample, although there were no differences in incidence of CSA. In terms of psychological characteristics, porn actresses had higher levels of self-esteem, positive feelings, social support, sexual satisfaction, and spirituality compared to the matched group. Last, female performers were more likely to have ever used 10 different types of drugs compared to the comparison group. A discriminant function analysis was able to correctly classify 83% of the participants concerning whether they were a porn actress or member of the matched sample. These findings did not provide support for the damaged goods hypothesis. 相似文献

The coming-out process for gay and bisexual men (GBM) involves crossing sexual identity development (SID) milestones: (1) self-awareness of sexual attraction to the same sex, (2) self-acceptance of an identity as gay or bisexual, (3) disclosure of this sexual identity to others, and (4) having sex with someone of the same sex. We examined trends in SID milestones by birth cohort in a 2015 U.S. national sample of GBM (n = 1,023). Birth cohort was independent of when men first felt sexually attracted to someone of the same sex (median age 11 to 12). However, with the exception of age of first same-sex attraction, older cohorts tended to pass other milestones at later ages than younger cohorts. Latent class analysis (LCA) of SID milestone patterns identified three subgroups. The majority (84%) began sexual identity development with same-sex attraction around the onset of puberty (i.e., around age 10) and progressed to self-identification, same-sex sexual activity, and coming out—in that order. The other two classes felt same-sex attraction during teen years (ages 12.5 to 18.0) but achieved the remaining SID milestones later in life. For 13% of men, this was during early adulthood; for 3% of men, this was in middle adulthood. Findings highlight the need to monitor ongoing generational differences in passing SID milestones. 相似文献

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
