This article analyzes the predictability of asset returns that are discounted using a consumption-based discount factor. The main objective of the analysis is to investigate how ancillary statistical assumptions affect the performance of this model. It is shown that, unlike tests of constant-discountrate models, tests of consumption-based models do not critically depend on statistical assumptions; for sufficiently high discount rates, there exist intuitively plausible rates of risk aversion for which appropriately discounted returns are unpredictable, regardless of the statistical specification. Test results are determined by serial correlation properties of prices and dividends and not by serial-correlation properties of returns. 相似文献
Ninety-nine self-identified lesbians provided definitions of what being a lesbian meant to them. A content analysis revealed two major categories: politically-based definitions and nonpolitical definitions. The political definitions included two highly interrelated subgroups, one of definitions based on woman-identification and the other including a broader world view that included affiliations with other oppressed groups. Nonpolitical definitions included four subgroups; those who defined lesbianism as sex/love with women, lesbianism as a true essence, just happening to love a woman, and lesbianism as only one small aspect of the person. There were only a few differences between women who cited political definitions and those with nonpolitical definitions. Lesbians who provided political definitions were more likely to identify themselves as feminists, were more involved in political activities and slightly more of them had a history of depression and eating disorders. Lesbians who provided nonpolitical definitions were more likely to have children, to have been raised in a conservative religion, and to think that they were born as lesbians. Various interpretations of the categories of definitions are provided.相似文献
Previous research suggests that Internet memes give voice to and unite otherwise silent and scattered social groups, making them popular in the most contemporary forms of practiced religion (Burroughs & Feller, 2015). This article aims to understand how religious institutions are utilizing memes to create a religious cultural experience compared to independent entities catering to the same audience. Researchers conducted a quantitative content analysis of 826 memes published by three distinct, interconnected entities affiliated with The Church of Jesus Christ of Latter-day Saints, including official Church organizations, unofficial Church organizations, and users with ties to the faith. Memes were examined for their content, form, and stance (Shifman, 2013). An analysis revealed that the LDS Church used its memes to present more serious, inspirational content, while users created memes that were more light-hearted and mixed LDS culture with pop culture. However, unofficial sources created more memes promoting LDS beliefs. 相似文献

The Gaussian rank correlation equals the usual correlation coefficient computed from the normal scores of the data. Although
its influence function is unbounded, it still has attractive robustness properties. In particular, its breakdown point is
above 12%. Moreover, the estimator is consistent and asymptotically efficient at the normal distribution. The correlation
matrix obtained from pairwise Gaussian rank correlations is always positive semidefinite, and very easy to compute, also in
high dimensions. We compare the properties of the Gaussian rank correlation with the popular Kendall and Spearman correlation
measures. A simulation study confirms the good efficiency and robustness properties of the Gaussian rank correlation. In the
empirical application, we show how it can be used for multivariate outlier detection based on robust principal component analysis. 相似文献
National competitiveness indices are often theoretical underdeveloped, limiting their engagement with academic literature. Because many are based on neoliberal ideology, a new approach is needed to incorporate governance and administration theory, and to enhance relevance to developing countries. This article introduces government competitiveness, a concept that recognizes overlooked factors like the role of social organizations, the use of diverse policy inputs and policy development processes, and the imperative to address human needs at all development stages. The conceptual foundation draws from systems theory, needs theory, and intervention stages theory to inform a comprehensive framework that bridges development scholarship and practice.
This paper evaluates the link between employee affective commitment and wages using a theoretical model predicting that affective commitment and wages can be complements. We estimate simultaneous quantile regressions based on a matched worker–employer sample of private sector workers from the UK's Workplace Employment Relations Survey 2004. Our results suggest that wages increase with increasing levels of affective commitment, consistent with the idea that the two are complements. 相似文献
