Weiter behandeln oder nicht?

Ein Fallbeispiel - Frau Schneider erkrankte im Alter von 73 Jahren an einer akuten myeloischen Leuk?mie (AML). Die eingeleiteten Therapien griffen nicht. Schlie?lich stimmte sie der Therapiebegrenzung zu. Vor welchen klinischen und normativen Herausforderungen stand das Behandlungsteam? Welche L?sungsans?tze für das praktische Vorgehen k?nnen aus diesem Fall geschlussfolgert werden?

The supportive expatriate spouse: An ethnographic study of spouse involvement in expatriate careers

Previous research on the influence of accompanying expatriate spouses has emphasized the negative impact on the business expatriates that could contribute to unsuccessful outcomes of the foreign assignments. But spouses’ influences could also be positive. Applying ethnographic field-work methodology, this study investigated female spouses’ involvement in the career of a sample of Danish business expatriates living in the same compound in Saudi Arabia. Results showed that the accompanying partners were active in trying to support and further their expatriate husbands’ immediate careers and repatriation opportunities by using social strategies, such as creating alliances and establishing social networks with influential others through social contacts and dinner parties. The female trailing partners also tried as a group to influence company decisions regarding working schedules, pay, and holidays. These findings are consistent with recent theoretical developments focusing on positive outcomes of the work–family interface and social capital theory and are in line with empirical research on repatriation and post-assignment careers.     

Improving Service Quality in Person-to-Person Encounters: Integrating Findings from a Multi-disciplinary Review

Although the core of most services is a person-to-person encounter, we still know very little about its underlying mechanisms as very few models or theories have been developed for these dynamic interactions between persons. An holistic approach to quality improvement is therefore suggested. Different prototypical person-to-person encounters may be studied on different levels and interfaces in service operations to eliminate inconsistencies. The aim of this contribution is to review some recent research findings for person-to-person encounters from the neighbouring management fields of services, operations and human resources in order to draw together their strategic implications for service managers. Some ontological and methodological considerations of studying person-to-person encounters from a qualitative perspective are discussed. The outline of a multi-disciplinary and learning-centred research approach is also suggested. Findings are integrated by a model of four generic and strategic processes for quality improvement in service operations. Finally, some implications for managers are proposed.     

How Do Investors' Expectations Drive Asset Prices?

Based on an extension of the process of investors' expectations to stochastic volatility we derive asset price processes in a general continuous time pricing kernel framework. Our analysis suggests that stochastic volatility of asset price processes results from the fact that investors do not know the risk of an asset and therefore the volatility of the process of their expectations is stochastic, too. Furthermore, our model is consistent with empirical studies reporting negative correlation between asset prices and their volatility as well as significant variations in the Sharpe ratio.
