No full textThis bachelor thesis explores the media reflection of the case of Claas Relotius, a former reporter for Der Spiegel, who was exposed by his colleague Juan Moreno as the author of serious manipulations and fabrications in his reports. The aim of the thesis is to analyze how five major national German newspapers Die Welt, Frankfurter Allgemeine Zeitung, Die Tageszeitung, Süddeutsche Zeitung and the weekly Die Zeit reported on the affair to what extent they acknowledged their own collaboration with Relotius. The methodological basis is a qualitative content analysis of selected articles, complemented by the study of archival materials and the findings of the investigative commission that Der Spiegel established immediately after the scandal was uncovered. The results show that all the media emphasized the impact of Relotius's actions on the credibility of journalism, highlighting various themes - from personal responsibility and the responsibility of Der Spiegel itself to criticism of the literary style of reportage, as well as systemic shortcomings of the profession, the pressure to evoke emotions and the role of journalism awards. Although the editorial boards openly admitted that they had also published Relotius's articles in the past, most avoided deeper self- criticism and framed the case..
Identifying critical service issues in the service encounter – a first step in the development of a conceptual model for the shipping industry
No full textTitle Identifying critical service issues in the service encounter – a first step in the development of a conceptual for the shipping industry Author Claas Boomgaarden Key Words Service Quality, Service Encounter, SERVQUAL, INDSERV, PDSQ, LSQM, Shipping Industry, Service Science, Service Dominant Logic, Relationship Marketing Purpose The purpose of this research is to provide a first step in the development of a conceptual model for service quality in the shipping industry. Theoretical Perspectives This study is embedded in the theoretical field of service quality. Due to the lack of applicable models for the shipping industry, the existing literature of service quality for the business-to-consumer as well as business-to-business sector where combined to provide the theoretical framework for this study. Even though other models were analysed and considered in the theoretical background, eventually models like the SERVQUAL model, the INDSERV model, as well as the Physical Distribution Service Quality (PDSQ) model and the Logistics Service Quality (LSQ) model built the guideline for the data collection process. Methodology In accordance with the explorative purpose of this research, a qualitative case study, with German freight forwarders as the unit of interest, was set up. The collection of empirical data and their analysis followed the abductive hermeneutic approach. Empirical Data The empirical data for this study was derived from eight semi-structured interviews with industry experts, which lasted between twenty minutes and one hour. Conclusion The study has shown that critical service issues are depending on the value and the implied requirements of the shipped product. Nevertheless, availability, time and price as well as a flawless and fast service and good contact to contact personnel were identified as critical service issues. In order to provide a first step in the development of a conceptual model for service quality in the shipping industry, the dimensions of responsiveness, reliability/discrepancy handling, flexibility and contact to contact personnel are proposed. Further, the study shows the interconnectivity of these dimensions and proposes enabler dimensions in the form of contact person quality and process quality. By identifying these critical service issues as well as the service dimensions and their interconnectivity, the partial adaptation of established service quality measurement systems is confirmed. However, also their shortcomings are presented and this gap is closed through modification or adaptation of new dimensions
Estimation and tests for power-transformed and threshold GARCH models
No full textConsider a class of power transformed and threshold GARCH(p,q) (PTTGRACH(p,q)) model, which is a natural generalization of power-transformed and threshold GARCH(1,1) model in Hwang and Basawa (2004) and includes the standard GARCH model and many other models as special cases. We ¯rst establish the asymptotic normality for quasi-maximum likelihood estimators (QMLE) of the parameters under the condition that the error distribution has ¯nite fourth moment. For the case of heavy-tailed errors, we propose a least absolute deviations estimation (LADE) for PTTGARCH(p,q) model, and prove that the LADE is asymptotically normally distributed under very weak moment conditions. This paves the way for a statistical inference based on asymptotic normality for heavy-tailed PTTGARCH(p,q) models. As a consequence, we can construct the Wald test for GARCH structure and discuss the order selection problem in heavy-tailed cases. Numerical results show that LADE is more accurate than QMLE for heavy tailed errors. Furthermore the theory is applied to the daily returns of the Hong Kong Hang Seng Index, which suggests that asymmetry and nonlinearity could be present in the ¯nancial time series and the PTTGARCH model is capable of capturing these characteristics. As for the probabilistic structure of PTTGARCH(p,q), we give in the appendix a necessary and su±cient condition for the existence of a strictly stationary solution of the model, the existence of the moments and the tail behavior of the strictly stationary solution

Cílem práce je analyzovat, jakým způsobem pět významných celoněmeckých deníků Die Welt, Frankfurter Allgemeine Zeitung, Die Tageszeitung, Süddeutsche Zeitung a týdeník Die Zeit informovaly o této aféře a do jaké míry zohlednily vlastní spolupráci s Relotiusem. Metodologickým základem je kvalitativní obsahová analýza vybraných článků, doplněná o studium archivních materiálů a závěrů vyšetřovací komise, kterou Spiegel zřídil bezprostředně po odhalení skandálu. Výsledky ukazují, že všechna média zdůrazňovala dopad Relotiusova jednání na důvěryhodnost žurnalistiky, přičemž vyzdvihovala různá témata - od osobní odpovědnosti a odpovědnosti samotného magazínu, přes kritiku literárního stylu reportáže, až po systémové nedostatky profese, tlak na emoce a roli novinářských ocenění. Přestože redakce otevřeně přiznaly, že Relotiusovy texty v minulosti také publikovaly, většina se vyhýbala hlubší sebekritice a rámovala kauzu především jako selhání Spiegelu či širšího mediálního systému. Práce tak dokládá, že případ Relotius mohl být pro média příležitostí k sebekritickému zamyšlení a změně,...Katedra německých a rakouských studiíDepartment of German and Austrian StudiesFaculty of Social SciencesFakulta sociálních vě
