The ongoing digitalization in the training sector produces new demands on the media‐didactical competence of trainers. We conducted an online survey of 279 trainers in Germany to investigate the relationships among media‐didactical competence, media‐didactical self‐efficacy, attitudes toward the use of digital media and the actual use of digital media in training. Furthermore, we compared trainers who attended a course on digital media with trainers who did not attend such a course. The analysis of the theoretically expected correlations between the variables resulted in not all hypotheses being accepted. The analysis of the group differences showed that the trainers who attended a course on digital media had higher media‐didactical competence and media‐didactical self‐efficacy scores and used digital media more often in training. There was no significant difference in negative attitudes. The implications for the promotion of the media‐didactical competence of trainers are discussed. 相似文献
Using Morningstar mutual fund stewardship grade data, we find that the governance mechanisms of mutual funds play a key role in their monitoring of portfolio firms and in their investment decisions. Mutual funds with better governance practices tend to vote responsibly on corporate governance proposals of their portfolio firms and also provide better return performance. Furthermore, these funds tend to avoid investing in poorly governed firms. The results suggest that funds with quality governance are more likely to act in the interest of their investors, and that costs associated with funds' monitoring of their portfolio firms do not adversely affect their return performance. 相似文献
We develop entrepreneurship and institutional theory to explain entrepreneurial growth aspirations across individuals and institutional contexts. Our framework generates hypotheses at the national level about the negative impact of higher levels of corruption, weaker property rights and greater government activity on entrepreneurs' aspirations to increase employment. We further explore whether individual's social networks compensate for weaknesses in national institutions. We use the Global Entrepreneurship Monitor surveys in 42 countries for 2001–2006, applying a multilevel estimation framework to test our ideas. We find that the relationship between growth aspiring entrepreneurs and institutions is complex; they benefit simultaneously from strong government (in the sense of property rights enforcement), and smaller government, but are constrained by corruption. Social networks mediate some but not all institutional deficiencies. 相似文献
We examine the relationship between volatility and past andfuture returns using high-frequency aggregate equity index data.Consistent with a prolonged "leverage" effect, we find the correlationsbetween absolute high-frequency returns and current and pasthigh-frequency returns to be significantly negative for severaldays, whereas the reverse cross-correlations are generally negligible.We also find that high-frequency data may be used in more accuratelyassessing volatility asymmetries over longer daily return horizons.Furthermore, our analysis of several popular continuous-timestochastic volatility models clearly points to the importanceof allowing for multiple latent volatility factors for satisfactorilydescribing the observed volatility asymmetries. 相似文献
This paper empirically examines the effect of biomass energy consumption and economic complexity on environmental sustainability in G7 economies. The current study attempts to report a comprehensive analysis of biomass energy and economic complexity on ecological and carbon footprints and carbon emissions. We employ data from 1990 to 2019 and adopt robust panel econometric techniques that account for the analysis's cross-sectional dependence. We conduct cointegration analysis, pooled ordinary least squares (OLS), system generalized method of moments (GMM) and conditional quantile model for our empirical analysis. The empirical findings show that both biomass energy consumption and economic complexity are detrimental to the ecological footprint and carbon footprint. Additionally, we find that globalization positively affects the environment, while we find some evidence that bureaucratic quality improves environmental quality. Finally, in line with other research, we find that economic growth has detrimental effects on the environment. Our results suggest that policymakers should be more cautious in promoting biomass as a clean energy source and that the G7 economies should take advantage of their leading position in innovation to invest more in sustainable practices and investment. 相似文献

In this article we analyze how privilege is dynamically constructed as well as contested. A positioning analysis of interviews with employees of a multinational organization reveals the construction of a hierarchy of privilege. As this hierarchy is based on English proficiency along with other diversity dimensions, privilege is multifaceted. Furthermore, privilege is also contested. Contesting English-proficiency–related privilege is connected to the speaker's position in the hierarchy of privilege. The analysis shows that both category membership and specific competences and skills cumulate to produce privileging effects, but also the possibilities for contesting privilege. At the same time, although the privilege gained by English proficiency is not invisible and is regularly contested, it is nevertheless silenced by those in advantage. 相似文献
The economic literature focuses mostly on faster ageing of population among developed countries; however, many developing countries experience even more dramatic pace of this process. Mauritius, with the median age of population higher than the world average since 1990s, represents a prominent example of such a case. In this paper, we analyse demographic developments in Mauritius and discuss their macroeconomic implications using an open-economy OLG model with demographic shocks. We project that a decline in the Mauritian interest rate and net foreign assets to GDP resulting from ageing will be accompanied by a temporary increase in GDP, consumption and investment. 相似文献
Expressed personality traits can play a pivotal role in convincing investors in crowdfunding. Our study answers the research question: What is the current body of knowledge regarding the relationship between personality factors and crowdfunding success and where are knowledge gaps where the literature is silent? In our literature review, we therefore analyze and categorize (1) the results provided by quantitative studies on the relationship between the personality of entrepreneurs and crowdfunding success and (2) the research gaps identified by the authors investigating personality in crowdfunding. We find that studies investigating the entrepreneur's personality, i.e. the Big Five, other baseline personality traits (self-efficacy, innovativeness, locus of control, and need for achievement) and the Dark Triad, find positive relationships between openness and crowdfunding success, while narcissism shows an inverted u-shaped relationship with crowdfunding success across articles. However, the effects of other personality traits on crowdfunding success are largely inconclusive. Further, we identify four main gaps in the literature. First, future studies should examine non-linear relationships between expressed personality traits and crowdfunding success. Second, there is a need for more studies that employ different methods like qualitative or mixed-method approaches. Third, replication studies in similar and different contexts are urgently needed. Fourth, a plurality of personality perspectives would strengthen future research (e.g., investor perspective, third party perspective). To our knowledge this is the first literature review of personality traits in crowdfunding. Our work aims to enrich our understanding of individual-level components in the underexplored alternative finance market.
