Binge-Watching and Psychological Well-Being: Media Use Between Lack of Control and Perceived Autonomy     

Viola C. Granow  Leonard Reinecke  Marc Ziegele 《Communication Research Reports》2018,35(5):392-401

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   

Maximal heart rate declines linearly with age independent of cardiorespiratory fitness levels

There have been many conflicting observations between the linear or curvilinear decline in maximal heart rate (HR_max) with age. The aim of this study was to determine if linear or curvilinear equations would better describe the decline in HR_max 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 HR_max 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 HR_max 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 HR_max.  相似文献   

浅论统计在现代企业管理中的作用     

杨宏明 《铜陵职业技术学院学报》2006,5(3)

随着我国的经济体制由社会主义计划经济转向社会主义市场经济,企业的性质、地位及其外部环境都发生了巨大的变化。企业是从事商品生产、流通和交换等活动的经济实体,实行自主经营、自负盈亏。企业被推向市场,参与市场竞争。企业在产、供、销等方面需要更多地来自市场的信息。统计作为企业管理中的一项基础性工作,正发挥着日益重要的作用。本文通过分析论述统计在新时期企业管理中的具体作用,进一步阐明了为实现这些作用,企业统计应从哪些方面开展工作。  相似文献

An Outreach Framework for Retaining Nontraditional Students at Open‐Admissions Institutions     

Michelle Q. Leonard 《Journal of College Counseling》2002,5(1):60-73

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   

Academic Follow-Up Data on Two Cohorts of High-Risk Transfer Children     

Leonard A. Jason  Karen E. Danner  Andrew M. Weine  Karen S. Kurasaki  Jay H. Johnson  Luann Warren-Sohlberg  Olga Reyes 《Early education and development》1994,5(4):277-288

Two cohorts of children from inner-city elementary schools were provided a tutoring intervention to help in their transition to new schools. Participants were third, fourth, and fifth grade children who were identified as having low-income status, evidencing lags on achievement tests, and experiencing stressful life events. The intervention involved an orientation program with twice weekly paraprofessional tutoring. Two and three year academic and sociometric follow-up data were collected. Those provided the intervention evidenced some improvements over time, and these changes were most prominent in the area of reading grades. Fewer significant findings were found on sociometric indices.  相似文献
