Notwendigkeit,Ziele und Inhalte einer Ethik-Ausbildung in der Betriebswirtschaftslehre

Although business administration scholars in German-speaking countries increasingly engage in business ethics research, their business schools have so far not systematically included ethics related contents into their standard curricula. Based on an understanding of business administration as an applied discipline that should not shun the scientific discussion of normative statements, this article argues that our field needs to address ethical questions not only in research but also in teaching. The subsequent analysis addresses aims, contents, and methods of teaching business ethics in higher education. Rather than teaching students ‘moral truths’, the main aim of business ethics education is seen in providing students with a variety of theories, concepts, and tools that are able to support them in ethical decision processes, which they are likely to encounter in their management careers.     

Interkulturelle Kommunikation als Voraussetzung für interkulturelles Coaching unter Berücksichtigung der rumänischen Kultur

Professional coaching in intercultural contexts requires adapting the “tool” of coaching to this specific focus. Coaching in intercultural contexts is based on a thorough understanding of intercultural communication. History, and specifically social history, of cultures and nations are essential to understanding intercultural processes. The intercultural coach also needs to possess advanced foreign language competence in order to communicate meanings in the target language.     

Fractional integration versus level shifts: the case of realized asset correlations

Long memory has been widely documented for realized financial market volatility. As a novelty, we consider daily realized asset correlations and we investigate whether the observed persistence is (i) due to true long memory (i.e. fractional integration) or (ii) artificially generated by some structural break processes. These two phenomena are difficult to be distinguished in practice. Our empirical results strongly indicate that the hyperbolic decay of the autocorrelation functions of pair-wise realized correlation series is indeed not driven by a truly fractionally integrated process. This finding is robust against user specific parameter choices in the applied test statistic and holds for all 15 considered time series. As a next step, we apply simple models with deterministic level shifts. When selecting the number of breaks, estimating the breakpoints and the corresponding structural break models we find a substantial degree of co-movement between the realized correlation series hinting at co-breaking. The estimated structural break models are interpreted in the light of the historic economic and financial development.     

Phillips-Perron-type unit root tests in the nonlinear ESTAR framework

Summary In this paper, we propose Phillips-Perron type, semi-parametric testing procedures to distinguish a unit root process from a mean-reverting exponential smooth transition autoregressive one. The limiting nonstandard distributions are derived under very general conditions and simulation evidence shows that the tests perform better than the standard Phillips-Perron or Dickey-Fuller tests in the region of the null. We would like to thank conference participants of the Pfingsttagung 2005 in Münster for their helpful comments.

The Bologna Process and the harmonisation of higher education systems in other world regions: a case from Southeast Asia

The Bologna Process has inspired harmonisation strategies for higher education systems in other parts of the world. However, developments in other contexts are not much under review in the European debate. The present article describes the case of Southeast Asia and the attempt to promote harmonisation of its higher education systems. It further compares the processes in ASEAN and the European Higher Education Area to then discuss open questions for future comparative research. To do so the authors re-contextualise data from a study in ASEAN against the background of future research needs in the field of higher education harmonisation.     

Contextual moderators of the link between national and European identity among European youth

Identification with Europe can constitute an important part of psychological citizenship for European citizens. From a self-categorization perspective, higher-order (e.g. with Europe) and lower order subgroup identities (e.g. with the nation) may interfere with each other if they are seen as incompatible. We were interested in contextual moderators at school and country level of youth’ national identity on identification with Europe. We used multi-level regression analyses based on data from the International Civic and Citizenship Education Study, collected from 14-year old students (n?=?71,282) from 22 European countries. Results showed strong positive effects of national identity at the individual, and classroom-level on European identity. However, main effects of national identity at the individual level were qualified by a number of interactions with contextual-level moderators. The relationship between national and European identity was weaker for adolescents attending classrooms or living in countries with lower average levels of trust in EU institutions. Living in countries with higher gender and income inequalities, less friendly immigration policies, and a communist past lessened the association between national and European identity. Results point to the powerful effects of context in shaping the relationship between national and European identity.
