Binge-watching—the intensive, consecutive viewing of televised series—has become a prevalent usage pattern of entertainment media, which may influence users’ psychological well-being both positively and negatively: On the one hand, binge-watching could increase viewers’ enjoyment, recovery experiences, and vitality through an increase in perceived autonomy. On the other hand, binge-watching can trigger goal conflicts and feelings of guilt, which may reduce well-being. Drawing on an online survey (N = 499), the present study examines the tension between these two mechanisms and their effects on users’ well-being. The data largely support the hypotheses: Binge-watching is perceived as recreational as long as goal conflicts and feelings of guilt can be avoided. Well-being, on the other hand, is positively affected by binge-watching-induced increases in perceived autonomy. These results corroborate the central role of self-determination as a link between media reception, media enjoyment, and psychological well-being.  相似文献

There have been many conflicting observations between the linear or curvilinear decline in maximal heart rate (HRmax) with age. The aim of this study was to determine if linear or curvilinear equations would better describe the decline in HRmax with age in individuals of differing cardiorespiratory fitness (CRF) levels. Treadmill cardiopulmonary exercise test (CPX) results from participants (1510 men and 1134 women; 18–76 years) free of overt cardiovascular disease were retrospectively examined using cross-sectional and longitudinal study designs. Participants completing ≥2 CPX with ≥1 year between test dates were included in the longitudinal analysis (325 men and 150 women). Linear and quadratic regressions were applied to age and HRmax for the whole cohort and respective CRF groups (high, moderate, and low, relative to age and gender normative values). To test for differences among linear, quadratic, and polynomial equations, the change in R2 (cross-sectional analysis) and Bayesian information criterion (BIC) (longitudinal analysis) from the linear to the more complex models were calculated. The quadratic or polynomial regression in the cross-sectional analysis, marginally improved the variance in HRmax explained by age compared to the linear regression for the whole cohort (0.2%), moderate fit group (0.3%), and low fit group (0.8%). With no improvements in the high fit group. BIC did not improve for any CRF category in the longitudinal analysis. In conclusion, the minimal differences among linear, quadratic, and polynomial equations in the respective CRF groups, emphasizes the use of linear prediction equations to estimate HRmax.  相似文献

This paper reports a study of pupils attitudes to Craft Design Technology (CDT), Technology (GCSE) and Technology A level in a Mid Glamorgan secondary school. Technology is regarded by the pupils as being intellectually demandng and having a high ‘employment value’. This seems to attract more able pupils (of both sexes) than would be the case for other CDT subject areas. Pupils perceive CDT: Technology to have the characteristics of Science subjects rather than those of Arts or Crafts. A significant proportion of female students in this case study are attracted to study A level Technology and investigations are continuing to identify the underlying reasons for this.  相似文献

The author discusses an outreach framework focused on retaining nontraditional students at small open‐admissions institutions. By using both campus and community resources, this approach integrates social work and counseling disciplines in an attempt to meet the needs of this population more effectively. Components of the program, implementation strategies, and limitations are also delineated.  相似文献
