For decades, the guiding principle and the programs of journalism studies at German universities have been gyrating around the integration of theory and practice. However, “integration” has been and still is interpreted in different manners: While education programs have, by and large, become non-contentious, research programs have diverged to journalistic practice depending on distance and proximity. Thereby, research is pushing against its limits, while at the same time impeding progress towards the aim of common-identity journalism studies as an integrative teaching and research field at universities. This paper appraises and formulates an amended concept and program. The drive to amend fuels on change in journalism, a context in which—due to the fast pace of innovation—journalistic education and research are faced with novel requisites. The aims and tasks of journalism studies are not any longer perceived as merely reconciling theory and practice into integrative education programs; rather, while acknowledging systemic disparities between science and social practice, the new paradigm includes integrative research that formulates, tests and evaluates transfer methods with a view to implementing evidence-based strategic decision-making in newsrooms. It is an explicitly normative concept: The quality of journalism represents the nexus of theoretical positions, choice and development of methodology, as well as outcome interpretation.  相似文献

Analysis of prices and volatility plays an important role in coffee market, especially for developing countries, whose small producers and economies rely heavily on income generated by coffee trade. This study explores the impact of coffee crop reports on price volatility for coffee futures contracts during 2004–2014. Overall, results indicate that crop reports generally affect price volatility. The impact is particularly stronger when they provide information following the flowering periods in Colombia, Brazil, and Vietnam, world’s major producers.  相似文献

Families experiencing transition and difficulty often need external support. Third places provide opportunity for external social connection and support through informal relationships. This paper examines how the third place model shares concepts with family theory and how it connects to the field of Family Science as a useful framework for helping individuals and families. The paper provides insights useful for the design of successful third places based on psychological, social, and physical attributes as avenues of support and well‐being. Also addressed are the benefits of the discovery, conceptualization, and application of third place and its usefulness for the field of Family Science.  相似文献

People’s interest in science topics is increasing — as is the coverage of science topics in the media. New popular science magazines and science pages are founded, and science programmes are launched on television. This trend stems from the fact that science topics increasingly affect developments in society and people’s everyday lives, and that they arouse emotions and influence other social systems such as politics, the economy, culture, religion and sports. This article offers an analysis of current changes in science journalism and the public relations of science. A market analysis served as basis for telephone interviews with editorial executives and heads of public relations departments. The interviews focused on respondents’ views on the future of science communication, the handling of science topics in newsrooms, and on future qualifications of science communicators. Evidently, science journalism is becoming more current, more controversial and more entertaining. The study formed the basis of a concept of an interdisciplinary bachelor’s program. This is why the article also deals with the consequences for journalism education.  相似文献

This paper develops the regime classification algorithm and applies it within a fully-fledged pairs trading framework on minute-by-minute data of the S&P 500 constituents from 1998 to 2015. Specifically, the highly flexible algorithm automatically determines the number of regimes for any stochastic process and provides a complete set of parameter estimates. We demonstrate its performance in a simulation study—the algorithm achieves promising results for the general class of Lévy-driven Ornstein–Uhlenbeck processes with regime switches. In our empirical back-testing study, we apply our regime classification algorithm to propose a high-frequency pair selection and trading strategy. The results show statistically and economically significant returns with an annualized Sharpe ratio of 3.92 after transaction costs—results remain stable even in recent years. We compare our strategy with existing quantitative trading frameworks and find its results to be superior in terms of risk and return characteristics. The algorithm takes full advantage of its flexibility and identifies various regime patterns over time that are well-documented in the literature.  相似文献

This study complements and extends prior research on the risk mitigation role of sustainable investing. We use a continuous measure of funds' sustainability traits, rather than a categorical approach, and assess impact on risk directly rather than by looking at fund performance in up versus down markets. We find that sustainable investing plays a significant role in mitigating total, systematic, and idiosyncratic risk of equity funds, even after controlling for other fund characteristics. Further evidence indicates that the explanation for the risk reduction role of sustainable funds largely runs through traits of the firms held in the funds.  相似文献

In this paper we analyze two different target regimes, flexible inflation targeting and nominal income targeting, under discretion in a simple dynamic macro model. The key results of our paper are: First, for both targeting regimes optimal monetary policy response leads to a shock-dependent feedback rule. Second, a demand shock is completely offset by both monetary strategies. Third, in case of a supply shock there is a significant difference between the two different targeting regimes. Under inflation targeting the policy makers face a trade-off between inflation and output stabilization. This trade-off depends on the weight Φ the policy makers attach to output stabilization relative to inflation stabilization in the loss function. In contrast, under nominal income targeting policy makers face a constant trade-off between inflation and real output growth: an increase in inflation leads to a fall in real output growth by an equal amount. Furthermore, in Appendix A we analyze a (linear) commitment solution for inflation targeting and compare it with the discretionary case. Under commitment, inflation is smaller and the output gap is larger than under discretion. In Appendix B, we investigate inflation targeting in a two-period time-lag version of the model. The qualitative results on the trade-off between inflation and output growth remain the same as in the basic model without time lag.

The colonial legacy of African underdevelopment is widely debated but hard to document. In this article, occupational statistics from Protestant marriage registers of historical Kampala are used to investigate the hypothesis that African gender inequality and female disempowerment are rooted in colonial times. We find that the arrival of Europeans in Uganda ignited a century‐long transformation of Kampala involving a gender Kuznets curve. Men rapidly acquired literacy and quickly found their way into white‐collar (high‐status) employment in the wage economy built by the Europeans. Women took somewhat longer to obtain literacy and considerably longer to enter into white‐collar and waged work. This led to increased gender inequality during the first half of the colonial period. However, gender inequality gradually declined during the latter half of the colonial era, and after Uganda's independence in 1962 its level was not significantly different from that of pre‐colonial times. The data presented here also support Boserup's view that gender inequality was rooted in indigenous social norms: daughters of African men who worked in the traditional, informal economy were less well‐educated, less frequently employed in formal work, and more often subjected to marital gender inequality than daughters of men employed in the modernized, formal economy created by the Europeans.  相似文献
