Media Freedom and Social Capital 总被引：1，自引：1，他引：0
Sanghoon Lee 《Journal of Media Economics》2017,30(1):3-18
This article examines the relationship between media freedom and social capital by using cross-country panel data. The hypothesis of the current study is the U-shaped relationship between media freedom and social capital, which is based on the claims that media freedom has a negative impact on bonding social capital and a positive effect on bridging social capital. To test the hypothesis, this study uses OLS and 2SLS regression methods, as well as panel data random effects regression. The empirical ?ndings support the hypothesis of the U-shaped relationship. 相似文献

The study used a five-wave latent growth model to compare two sets of competing hypotheses about the influence of overall computer and Internet use on mental health. The secondary data set from the Korean Youth Panel Survey (KYPS) with a valid sample size of 2,003 respondents was used for the analysis. The mediating role of friendship–closeness was examined to compare the social augmentation hypothesis with the social displacement hypothesis. The mediating role of academic stress was tested to compare the mood enhancement hypothesis with the problematic Internet use (PIU) model. The study was consistent with the social displacement hypothesis, where a higher initial computer and Internet use predicted a lower initial friendship–closeness, which, in turn, resulted in a faster decrease in mental health. The study provided reconciliation for the mood enhancement hypothesis and the PIU model. Although a higher initial computer and Internet use predicted lower initial mental health levels through academic stress, schoolchildren and adolescents with more computer and Internet use experienced a slower decrease in mental health because of the mediating role of academic stress. 相似文献

This research explores the hypothesis that social stress, as indexed by rising unemployment in society, leads to increased preference for crime drama on TV. This hypothesis is tested by relating the unemployment rates in the U.S., Canada, and Germany over several years with national trends for the relative popularity of crime drama (i. e., as compared to the popularity of other program categories). Support for this hypothesis is found in the U.S. and in Canada. 相似文献

The purpose of this paper was to identify and measure variables in the academic environment which best predict (estimate) circulation of monographs by academic subjects. Fall 1974 circulation at the University of Southwestern Louisiana was the dependent variable. Academic department was the unit of analysis. Subjects were defined as sixty-three academic departments including one miscellaneous category. The subject of each circulated book was categorized in one of the sixty-three. Twelve independent variables were identified: the hard/soft, pure/applied, and life/nonlife characteristics; credit hours, lower-level course enrollments, upper-level course enrollments, master's-level enrollments, Ph.D. -level enrollments, shelflist, Ph.D. program, master's program, and bachelor's program. Three linear regression hypotheses were formulated: a full twelve-variable hypothesis, an eleven-variable hypothesis excluding shelflist, and a three-variable subject-characteristic hypothesis. For the full 12-variable hypothesis, only shelflist, master's-level enrollments, hard/soft, and upper-level enrollments, in that order, were significant, accounting for 76% of the variance. This was called the shelflist model. For the eleven-variable hypothesis without shelflist, only credit hours, hard/soft, and upper-level enrollments, in that order, were significant, accounting for 60% of the variance. This was called the nonshelflist model. For the three-variable subject-characteristic hypothesis, onyl pure/applied and hard/soft, in that oder, were significant, accounting for 26% of the variance. Regression equations for estimating circulation were formulated. Estimates are given using the shelflist model. 相似文献
