Is the cryptocurrency market a hedge against stock market risk? A Wavelet and GARCH approach

This study analyses six major cryptocurrencies and four global stock markets to explore the role of cryptocurrencies as a hedge, safe haven, and diversifier in stock markets. The study employs ADCC-GARCH and Wavelet Coherence Technique, using daily data from 4 January 2017 to 28 February 2023. The study has found that stock returns and unstable cryptocurrency returns have high volatility persistence in the long run. Besides, while unstable digital currencies (Bitcoin, Ethereum, Binance Coin, and Dogecoin) serve as a hedge during stable economic periods, they have not been a hedge during economic turmoil in the stock markets. Conversely, stablecoins (Tether and USD Coin) have been shown to have acted as a hedge during normal economic times and have offered a safe haven during economic downturns. Except for Tether, all cryptocurrencies' diversification capacity is time-varying. In stable economic conditions, they serve as diversifiers, but during turmoil, they do not. However, Tether serves as a diversifier regardless of the financial situation. Finally, the present investigation is expected to offer crucial information on hedge, safe haven and diversification for quasi-investors.     

Microaggression,anxiety, trigger warnings,emotional reasoning,mental filtering,and intellectual homogeneity on campus: A study of what students think

College campus life is changing based on pressures to create safe environments for students to learn. Much of this change has been outlined in an article by Lukianoff and Haidt entitled “The Coddling of the American Mind.” The authors of the present article asked 188 students from two universities if microaggressions, trigger warnings, emotional reasoning, and mental filtering are prevalent on campus and whether colleges are promoting these concepts. The results show that the majority of students believe that universities must change the way these concepts are addressed to prevent intellectual homogeneity and to adequately prepare them for their business professions.     

Von pragmatischen Post-Docs und progressiven PraktikernAbout Pragmatic Post-docs and Progressive Practitioners

Scientific journals are a key factor for the integration of a research discipline. For their integrative capacity it is mainly important how members of a discipline use these journals as readers and authors and how they assess them. To gain more insight into this topic, all members of the German Society for Journalism and Communication Science (DGPuK) were asked to take part in an online survey during the summer of 2015. Object of this survey were the three journals Publizistik, Medien & Kommunikationswissenschaft and Studies in Communication | Media. Participants were asked about the utilization of those journals, their fulfillment of general expectations towards journals in German communication science as well as about publication behavior and expectations towards the publication process. Using a cluster analysis, participants were split in five different groups, discriminant in terms of expectations, assessments and forms of utilization. Results show that the analyzed journals still do not use their full potential to create long-term commitment, especially among younger academics.     

Beziehen sich Medien immer mehr auf Medien?

The media are becoming more and more media-referential. This thesis has become quite common among communication scholars. When reviewing the relevant literature, however, it becomes clear that terms such as self-referentiality or media-orientation are used to decribe a great variety of different phenomena. In addition, there is a lack of empirical evidence to support the notion of a growing frequency of media references in the media. Moreover, the discussion about media reliance and its changes is based on different theoretical approaches, some of which do not make any reference to other such approaches. Against that backdrop, this article first identifies different dimensions of self-or media-referentiality. Second, empirical evidence is presented that speaks for or against an increase of self-or media-referentiality. Third, the usual theoretical approaches used in explanations of self-or media-referentiality are discussed. Fourth, it is explained how an integrative social theory — the structural-individualistic approach — can be used as a basis for the explanation of changes in self-or media-referentiality. Finally, possible effects of such a development are discussed.     

E-Learning in der Kommunikations- und Medienwissenschaft

Using electronic media as teaching and learning tools is no longer a novelty; the fast development and diffusion of §new media”, such as CD-ROM and theWorldWideWeb, have given the use of these media a big boost in recent years. Thus, a number of electronic learning projects have been developed in the field of communication and media studies, of which, however, no general overview was available so far. This article provides such an overview, allows for classification and evaluation of these projects, and thus represents a prerequisite for the future success of such projects. A survey by the authors among communication and media studies departments in German-speaking countries accounted for 14 electronic learning projects that showed fairly diverse emphases with respect to their contents, concepts, didactics, technology, and organisation. In a case study on the Leipzig-based §Distance Learning Propädeutikum" (DLP), the article explores the advantages of electronic learning systems and discusses the challenges in the development and application of such systems. This section also draws on the results of a project-specific evaluation. Both the survey and the case study show that rather than substituting courses or cutting costs on instructors, the main advantage of electronic learning systems lies in their ability to make teaching and learning processes more independent of temporal and spatial constraints.     

Aspects of complexity in citizen–bureaucrat corruption: an agent-based simulation model

In this paper, the complexity-based approach is used to analyse corruption and its internal economics and dynamics. To better understand the drivers of corruption, we employ an agent-based model with heterogeneous agents (bureaucrats and citizens), the interactions of which determine the level of corruption in a society. The emergence of a prevailing social norm of corruption is shown to be significantly influenced by the initial conditions (i.e., history and habits). A cost analysis demonstrates that a relatively limited financial investment is required for the phase transition from the corrupt to the non-corrupt state. The concept of opportunity costs is used to express the value of information shared within an agent’s social group that improves agent decision-making. Incomplete information and uncertainty in the legal system help to reduce corruption by promoting a fear of engaging in corruption in a society. The results of this research may offer useful insights for informing an effective anti-corruption policy.

     

Open issues in happiness research

Happiness research is one of the most vivid and fruitful parts of modern economics. The focus is on empirical findings. In contrast, theoretical work has been rather neglected. The paper deals with three areas needing more analytical work: the choice or imposition of comparison or reference groups; and the extent, speed and symmetry of adaptation to positive and negative shocks on happiness. In both areas, theoretical propositions are derived which can in the future be empirically tested. The third area relates to the political economy of happiness. Many governments intend to take the happiness index as a criterion of how successful their policies are. As a consequence, survey respondents get an incentive to misrepresent their happiness level, and governments to manipulate the aggregate happiness indicator in their favor. A country’s constitution must induce governments to carefully observe human rights, democracy, the decentralization of political decision making, and market institutions and provide people with the possibility to acquire a good education and find a suitable job.
