The objective of this study was to measure the relationships between online sexual compulsivity, three dimensions of dissociation (absorption, depersonalization, and amnesia), and past child abuse among men who have sex with men (MSM). A total of 517 MSM, recruited from Internet chat rooms, completed the survey. Results indicated that past child abuse was significantly related to dissociation but not online sexual compulsivity. It was also found that the amount of time MSM spent online in a one-week period, in general and specifically engaged in sexual activity, was significantly related to online sexual compulsivity and three dimensions of dissociation. Online sexual compulsivity was a significant predictor of absorption, depersonalization, and amnesia. Implications for clinicians and future research are presented.  相似文献

Adding to the debate on the integrative or marginalizing nature of female part-time work, this article provides a comparative analysis of the implications of female part-time work for different intrinsic job quality dimensions and job satisfaction. Drawing on national micro-data from Britain, Germany, the Netherlands, and Sweden, our multivariate analyses show cross-national similarities in terms of lower job learning opportunities for female part-timers. We found a significantly higher incidence of repetitiveness only among Swedish female part-timers and lower degrees of task discretion among British, Dutch, and Swedish women working part-time hours. Female part-timers were either equally satisfied with their work as female full-timers or even more satisfied. This held true also after accounting for the lower intrinsic job quality of part-time work. While women working part-time hours were as affected by their job quality characteristics as were full-timers, we conclude that the shorter hours of work per se provide an important additional source of job satisfaction.  相似文献

We exploit a natural experiment within each National Football League game, finding the first evidence in professional sports that referees succumb to the pressures of satisfying team personnel in the vicinity of possible violations. Using generalized additive models for binomial outcomes, we show that these sideline‐based differences in penalty rates, which are observed on common but influential penalties including pass interference and holding, peak near the centralized location of players and coaches on the sideline. With sizable interests in referee decisions, coaches and players often try to manipulate referee behavior with verbal and nonverbal communications; such actions appear to be persuasive.

Increased physical activity is positively associated with better health in community-dwelling older persons. It is unclear whether physical activity also influences success of inpatient rehabilitation. For the assessment of physical activity in inpatient rehabilitation the Physical Activity in Inpatient Rehabilitation Assessment (PAIR), a short questionnaire based on five questions, was developed and preliminary validated. In this study, the PAIR was validated against a sensor-based physical activity measurement. Seventy functionally impaired and cognitively mostly intact patients of a German geriatric inpatient rehabilitation clinic who had undergone hip surgery (n?=?62 women, median age?=?83 years) participated. Physical activity was measured using the PAIR and a sensor-based activity monitor (Physilog ®; BioAGM, CH). Assessments were conducted at admission (T1) and 2 weeks later (T2) during the rehabilitation process. To assess concurrent and predictive validity, Spearman correlations and linear regression models were calculated using sensor-based walking activity and uptime activity (walking and standing time) as dependent variables. Criterion-related concurrent validity using physical activity sensors was weak to moderate. Correlations were slightly higher at T2 (r?=?0.45-0.53) than at T1 (r?=?0.44-0.46). The objectively measured variance of physical activity, explained by the PAIR, ranged from 25 to 43 %. PAIR activity scores and sensor-based walking or total activity increased in a dose-dependent manner, confirming the scoring system of the PAIR. The application time was usually less than 2 min. The validity of the PAIR is weak to moderate when compared to a sensor-based activity monitor and comparable to existing physical activity assessments for community-dwelling older adults.  相似文献
