Maladaptive coping mechanisms influence health-related quality of life (HRQoL) of individuals facing acute and chronic stress. Trait emotional intelligence (EI) may provide a protective shield against the debilitating effects of maladaptive coping thus contributing to maintained HRQoL. Low trait EI, on the other hand, may predispose individuals to apply maladaptive coping, consequently resulting in lower HRQoL. The current research is comprised of two studies. Study 1 was designed to investigate the protective effects of trait EI and its utility for efficient coping in dealing with the stress caused by chronic heart failure (CHF) in a cross-cultural setting (Pakistan vs Germany). N = 200 CHF patients were recruited at cardiology institutes of Multan, Pakistan and Würzburg as well as Brandenburg, Germany. Path analysis confirmed the expected relation between low trait EI and low HRQoL and revealed that this association was mediated by maladaptive metacognitions and negative coping strategies in Pakistani but not German CHF patients. Interestingly, also the specific coping strategies were culture-specific. The Pakistani sample considered religious coping to be highly important, whereas the German sample was focused on adopting a healthy lifestyle such as doing exercise. These findings are in line with cultural characteristics suggesting that German CHF patients have an internal locus of control as compared to an external locus of control in Pakistani CHF patients. Finally, the findings from study 1 corroborate the culture-independent validity of the metacognitive model of generalized anxiety disorder.
In addition to low trait EI, high interoception accuracy (IA) may predispose individuals to interpret cardiac symptoms as threatening, thus leading to anxiety. To examine this proposition, Study 2 compared individuals with high vs low IA in dealing with a psychosocial stressor (public speaking) in an experimental lab study. In addition, a novel physiological intervention named transcutaneous vagus nerve stimulation (t-VNS) and cognitive reappraisal (CR) were applied during and after the anticipation of the speech in order to facilitate coping with stress. N= 99 healthy volunteers participated in the study. Results showed interesting descriptive results that only reached trend level. They suggested a tendency of high IA individuals to perceive the situation as more threatening as indicated by increased heart rate and reduced heart rate variability in the high-frequency spectrum as well as high subjective anxiety during anticipation of and actual performance of the speech. This suggests a potential vulnerability of high IA individuals for developing anxiety disorders, specifically social anxiety disorder, in case negative self-focused attention and negative evaluation is applied to the (more prominently perceived) increased cardiac responding during anticipation of and the actual presentation of the public speech. The study did not reveal any significant protective effects of t-VNS and CR.
In summary, the current research suggested that low trait EI and high IA predicted worse psychological adjustment to chronic and acute distress. Low trait EI facilitated maladaptive metacognitive processes resulting in the use of negative coping strategies in Study 1; however, increased IA regarding cardioceptions predicted high physiological arousal in study 2. Finally, the German vs. the Pakistani culture greatly affected the preference for specific coping strategies. These findings have implications for caregivers to provide culture-specific treatments on the one hand. On the other hand, they highlight high IA as a possible vulnerability to be targeted for the prevention of (social) anxiety.
Die Unabhängigkeit des Abschlussprüfers ist von anhaltender Relevanz, wird jedoch immer wieder in Frage gestellt. Der Fokus von Regulierungsbehörden und Forschung liegt auf kapitalmarktorientierten Unternehmen. Die Unabhängigkeit kann besonders gefährdet sein, wenn Schutzmechanismen, wie z. B. die Haftung oder das Risiko eines Reputationsverlustes, besonders schwach ausgeprägt sind. Es kann abgeleitet werden, dass bei privaten Unternehmen das Risiko eines Reputationsverlustes im Vergleich zu kapitalmarktorientierten Unternehmen geringer ist. Weiterhin ist das Haftungsrisiko für den Abschlussprüfer in Deutschland verglichen mit angelsächsischen Ländern geringer.
Damit untersucht die Arbeit die Unabhängigkeit in einem Umfeld, in dem diese besonders gefährdet ist. Als Surrogat wird die Wahrscheinlichkeit einer Going-Concern-Modifikation („GCM“) herangezogen. GCM können als Indikator für die Prüfungsqualität besonders geeignet sein, da sie ein direktes Ergebnis der Tätigkeit des Abschlussprüfers sind und von ihm formuliert und verantwortet werden. Für das Surrogat GCM ist für Deutschland im Bereich der privaten Unternehmen bislang keine Studie bekannt.
Accounting plays an essential role in solving the principal-agent problem between managers and shareholders of capital market-oriented companies through the provision of information by the manager. However, this can succeed only if the accounting information is of high quality. In this context, the perceptions of shareholders regarding earnings quality are of particular importance.
The present dissertation intends to contribute to a deeper understanding regarding earnings quality from the perspective of shareholders of capital market-oriented companies. In particular, the thesis deals with indicators of shareholders’ perceptions of earnings quality, the influence of the auditor’s independence on these perceptions, and the shareholders’ assessment of the importance of earnings quality in general. Therefore, this dissertation examines market reactions to earnings announcements, measures of earnings quality and the auditor’s independence, as well as shareholders’ voting behavior at annual general meetings.
Following the introduction and a theoretical part consisting of two chapters, which deal with the purposes of accounting and auditing as well as the relevance of shareholder voting at the annual general meeting in the context of the principal-agent theory, the dissertation presents three empirical studies.
The empirical study presented in chapter 4 investigates auditor ratification votes in a U.S. setting. The study addresses the question of whether the results of auditor ratification votes are informative regarding shareholders’ perceptions of earnings quality. Using a returns-earnings design, the study demonstrates that the results of auditor ratification votes are associated with market reactions to unexpected earnings at the earnings announcement date. Furthermore, there are indications that this association seems to be positively related to higher levels of information asymmetry between managers and shareholders. Thus, there is empirical support for the notion that the results of auditor ratification votes are earnings-related information that might help shareholders to make informed investment decisions.
Chapter 5 investigates the relation between the economic importance of the client and perceived earnings quality. In particular, it is examined whether and when shareholders have a negative perception of an auditor’s economic dependence on the client. The results from a Big 4 client sample in the U.S. (fiscal years 2010 through 2014) indicate a negative association between the economic importance of the client and shareholders’ perceptions of earnings quality. The results are interpreted to mean that shareholders are still concerned about auditor independence even ten years after the implementation of the Sarbanes-Oxley Act. Furthermore, the association between the economic importance of the client and shareholders’ perceptions of earnings quality applies predominantly to the subsample of clients that are more likely to be financially distressed. Therefore, the empirical results reveal that shareholders’ perceptions of auditor independence are conditional on the client’s circumstances.
The study presented in chapter 6 sheds light on the question of whether earnings quality influences shareholders’ satisfaction with the members of the company’s board. Using data from 1,237 annual general meetings of German listed companies from 2010 through 2015, the study provides evidence that earnings quality – measured by the absolute value of discretionary accruals – is related to shareholders’ satisfaction with the company’s board. Moreover, the findings imply that shareholders predominantly blame the management board for inferior earnings quality. Overall, the evidence that earnings quality positively influences shareholders’ satisfaction emphasizes the relevance of earnings quality.
Media have become omnipresent in children’s and youths’ everyday lives, and they also offer rich chances and challenges for educational contexts. On the one hand, media can, for example, support students’ learning effectively, enhance lessons with innovative tools and methods and help individualize teaching and learning processes. On the other hand, students need to learn, e.g., how to use these media, how to select and evaluate them and how to act responsibly in a digitalized and mediatized world. Teachers are a core stakeholder in this context. To take advantage of the benefits media offer for teaching and learning processes, to support students in the acquisition of respective competencies and to fulfill numerous other media-related tasks and challenges, teachers need to acquire respective competencies in their initial teacher education, which can be summarized as media-related educational competencies.
The relevance of these competencies is evident on different levels. In related research, respective competency models are developed, and in practices of teacher education, competencies are measured and efforts are taken to advance the competencies of preservice teachers. Against this background, this semi-cumulative dissertation presents a theory-based and empirical analysis of the competencies in question from a comprehensive and multidimensional perspective. In accordance with the central aspects outlined, the three systematic main fields focused on are models of media-related educational competencies, their measurement and practices of advancement in teacher education, as well as the interplay of these three fields. The dissertation takes on an international comparative perspective and focuses on the examples of initial teacher education in Germany and the USA.
The article-based dissertation comprises three main parts, framed by introduction and conclusion. The introduction provides a basis for the following work with regards to terminology, scope of research and overall methodology. The first main part is concerned with models of media-related educational competencies and includes a theory-based systematic comparison of three relevant models. This part explicates the varieties between competency models, and it discusses central aspects of selection and application. In Part II, methods and varieties of competency measurement are focused on, and an article is presented which shares results of an exploratory quantitative measurement of the respective competencies of German and US preservice teachers. Overall, this part reveals the potential and limitations of competency measurement and transfers these conclusions to the competency models introduced in Part I. Part III is concerned with an analysis of current practices of advancing media-related educational competencies in Germany and the USA. In this context, stakeholders influencing these practices will be systemized and analyzed in their role and impact. The article included in Part III introduces interviews which were conducted to achieve insights into the perspectives of selected experts, regarding relevant models, practices and outcomes of media-related teacher education in Germany and the USA.
Finally, the Conclusion of the dissertation will draw together the different strands, clarify the close connection between the domains of modeling, measuring and advancing the competencies in question and discuss the interdependencies of these three dimensions. These perspectives help both to contextualize and bring together important facets which have often been treated separately in related research and will add new facets to ultimately achieve a comprehensive and multifaceted viewpoint.
Against the background of the intercultural comparative perspective, the results and findings will ultimately achieve an enhanced and deep analysis and reflection on the complex field of media-related educational competencies in Germany and the USA and beyond.
