Alles ist gut

All is good — wisdom’s use in managementIn crisis periods the demand for orientation knowledge grows. Everybody is looking for the answers to the fundamental questions of life. For over 2000 years philosophy has such a knowledge: wisdom. But what is wisdom and what is its use for the management? On this question the essay with Kant gives the answer: Wisdom is the way of self-knowledge. And self-knowledge is the very source of each vision, without which there is no successful entrepreneurship.     

Braucht Coaching eine philosophisch begründete Ethik?

Does coaching need a philosphically substantiated ethics? On the foundation of a systemic value oriented imperative for coachingThe general claim that coaches have to take responsibility for their clients is in contrast to the low interest in scientific discussion about ethics in coaching. One of the reasons for that seems to be the fact that this discussion is dominated by systemic thinking and its conviction that ethical aspects should be discussed as matter of contingency. From a philosophical point of view we can realize that this statement contains many ethical implications. Concerning a further development of coaching theory the author discusses these implications with regard to philosophical concepts of Kant, Habermas, Prange, Heidegger, Bauman and the Dalai Lama leading to the suggestion that systemic thinking should be more based on value orientation. On this theoretical grounds an ethical coaching imperative can be formulated with regard to the “categorical imperative” of Kant.     

Optimal semi-online algorithm for scheduling with rejection on two uniform machines

In this paper we consider a semi-online scheduling problem with rejection on two uniform machines with speed 1 and s≥1, respectively. A sequence of independent jobs are given and each job is characterized by its size (processing time) and its penalty, in the sense that, jobs arrive one by one and can be either rejected by paying a certain penalty or assigned to some machine. No preemption is allowed. The objective is to minimize the sum of the makespan of schedule, which is yielded by all accepted jobs and the total penalties of all rejected ones. Further, two rejection strategies are permitted thus an algorithm can propose two different schemes, from which the better solution is chosen. For the above version, we present an optimal semi-online algorithm H that achieves a competitive ratio ρ _H (s) as a piecewise function in terms of the speed ratio s.     

Zur Wirkung von Neukunden-Promotions auf Bestandskunden

Service providers frequently offer better deals to prospective customers than they offer to customers who prolong their contracts. The present paper examines the effectiveness of incentives on new customers and, perhaps even more significantly, assesses negative effects on existing customers. To test the hypothesized effects, a series of two experiments was conducted. Results indicate that promotions that are offered exclusively to prospective customers have a negative effect on existing customers, and that this negative effect is stronger for customers with a short relationship age and for those at the end of their contract life-cycle. The unfairness and inequity perceived by existing customers can be substantially reduced if these customers are offered the opportunity to receive a part of the promotion value, while the promotion??s effectiveness to attract new customers remains unaffected.     

Kapitalmarktorientierte Unternehmensbewertung bei asymmetrischer Besteuerung von Soll- und Habenzinsen

Drukarczyk and Lobe argue that the value of a company depends on individual preferences for leveraged or unleveraged companies if debt and credit interest rates after personal taxes differ. Consequentially they derive two preference-dependent valuation formulas. Based on these results an increasing amount of literature proposing preference-dependent valuation formulas emerged. We claim that this has to be viewed critically. In order to show that even in a world of different debt and credit interest rates after personal taxes a market value can be determined we develop a new version of the Tax CAPM. Based on this model the market value of leveraged and unleveraged companies is derived. Finally we show that the corresponding valuation function significantly differs from the preference-dependent valuation formulas.     

Coaching und Psychotherapie — Differenz und Konvergenz

Coaching and psychotherapy — difference and convergence. A discussion on counseling between professional and personal issuesThe author discusses the relation between coaching and psychotherapy. He emphasises several crucial differences, but here he is concerned with the interfaces between these formats. He demonstrates, that in many cases psychotherapeutic views — basing on corresponding qualifications — may offer an important improvement of coaching. This is illustrated by some case studies.     

Was tun Lektoren?

What is the work of editors? Counselling of a ?service in background“The work of editors as employees in publishing houses or as free lancers is a ?service in background“ and hence it is less well-known in comparison with other media professionals. Nevertheless, editors have an important role as intermediary between authors and the reading public. The author delineates the profession of editors and the technical aspects of their work and explains some typical conflicts which may be relevant to a coaching of editors.     

Determinanten des Informationsgehalts von Managementprognosen – eine empirische Untersuchung anhand der DAX und MDAX-Unternehmen

In this article the characteristics and determinants of the information content of management earnings forecasts of the German DAX and MDAX companies between 2002 and 2005 are analyzed. As proxy for the information content I use the precision of the wording of a forecast. I can show that the forecasts of MDAX companies are more precisely formulated than those of DAX companies. Furthermore forecasts are formulated more precisely, when companies have, (1) a lower percentage of intangible assets, (2) lower market capitalization, (3) lower volatility of earnings and (4) a higher need for external financing.     

Pregnancy-related dropouts and gender inequality in education: A life-table approach and application to Cameroon

In this study, I used a life-table approach to estimate how much hypothetical reductions in pregnancy-related dropouts would help close the gender gap in educational attainment. Using the schooling histories of 6,686 pupils, I partitioned Cameroon's gender gap in education into "pregnancy-related" and "non-pregnancy-related" components and simulated the impact of reductions in pregnancy-related dropouts on this gap. The results suggest that such reductions would have substantial payoffs in this setting, but payoffs would be the greatest where societies also address gender inequities before puberty and outside the realm of pregnancy. Reductions in pregnancy-related dropouts complement but do not replace efforts to reduce gender discrimination in schooling. Recent data from Demographic and Health Surveys should make it possible to extend this analysis to other countries.
