Data warehouse systems have become a basic technological infrastructure in management decision making. Nevertheless, the overall utility of data warehouses remains unmeasured in most practical cases. As a consequence of this, IT-managers do not possess appropriate means to evaluate warehouse benefits in order to decide about investments in warehousing technology. This paper develops a controlling instrument for data warehouse systems based on the Balanced Scorecard (BSC) approach. On the basis of the technological aspects of data warehouse systems, the BSC perspectives are developed and populated with relevant objectives and measures for datawarehouse success. These perspectives are integrated into a consistent data warehouse scorecard. Finally, this instrument provides a holistic approach to drive the performance of data warehouse systems.
Building on Hofstede's finding that individualism and social hierarchy are incompatible at the societal level, the authors examined the relationship between individualism-collectivism and orientations toward authority at the individual level. In Study 1, authoritarianism was related to three measures of collectivism but unrelated to three measures of individualism in a U.S. sample (N = 382). Study 2 used Triandis's horizontal-vertical individualism-collectivism framework in samples from Bulgaria, Japan, New Zealand, Germany, Poland, Canada, and the United States (total N = 1,018). Both at the individual level and the societal level of analysis, authoritarianism was correlated with vertical individualism and vertical collectivism but unrelated to horizontal collectivism. Horizontal individualism was unrelated to authoritarianism except in post-Communist societies whose recent history presumably made salient the incompatibility between state authority and self-determination.
Every modern institution involved in higher education needs a Learning Management System (LMS) to handle learning and teaching processes. It is necessary to offer e.g. electronic lecture materials to the students for download via the internet. In some educational contexts, it is also necessary to offer internet tutorials to be able to give the students more personal support and accompany them through the whole lecture period. Many organisations have introduced commercial LMS and gained the experience that monolithic solutions do not fulfil the dynamic requirements of complex educational institutions and are very cost-intensive. Therefore, many universities face the decision to stick to their commercial LMS or to switch to a potentially more cost-effective and flexible solution, for instance by adopting available Open Source LMS. Since we have made profound experience in developing and operating an Open Source LMS, this contribution enlightens the main characteristics of this alternative. This paper describes a use case dealing with a full product lifecycle (development, deployment, use and evaluation) of an Open Source LMS at the University of Muenster (Germany). It identifies relevant instruments and aspects of system design which software architects in practical application domains should pay attention to.
Model Driven Architecture (MDA): Integration and Model Reuse for Open Source eLearning Platforms

Business-driven development favors the construction of process models
at different abstraction levels and by different people. As a consequence, there is a demand for consolidating different versions of process models by merging them. In this paper, we study a basic scenario, derive requirements and present a prototype for detecting and resolving changes between process models.
The purpose of this study was to evaluate which mode of birth first-time mothers in Germany and in the USA prefer and how this desire is related to maternal well-being and sense of coherence. The paper describes emotional well-being postpartum in relationship to mode of birth. For data collection a prospective cohort study was conducted in both countries. A self-administered questionnaire including validated instruments (WHO-5 Well-Being Index, Sense of Coherence Scale and Edinburgh Postnatal Depression Scale) was used. Results showed that only a few of the pregnant women in Germany and the USA preferred to deliver by caesarean section. There was a relationship between women's well-being, women's sense of coherence and the preferred mode of birth. The majority of women who wanted a caesarean section delivered in this way. No relationship was found between women's well-being and the type of birth experienced. Well-being in both samples generally decreased after giving birth, but there was a difference between German and American first-time mothers on the postpartum well-being and depression scores. German mothers had a higher postnatal quality of life and lower postnatal depression scores. To give families the opportunity for a healthy start, midwives and obstetricians should try to enhance women's well-being and they should give some thought to health professionals' decision-making processes. Expanded postpartum care might have an impact on women's depression scores..
When speaking about eBusiness as applied to the healthcare market two questions arise immediately. Firstly, what is eBusiness? Secondly, why is eBusiness in healthcare different from eBusiness in other sectors?
Within the arena of eBusiness in healthcare, the focus is on purchasing and selling online as the most advanced application. In this book, the Authors consider both the perspective of the healthcare providers and that of the suppliers, showing the interdependencies between the two and developing concepts for a new synergistic cooperation.
eBusiness in Healthcare raises awareness of and interest in electronically mediated business processes in healthcare to a large audience including healthcare informaticians, medical business managers, clinicians, pharmacists and scientists. By taking an international approach to the topic the authors demonstrate the many similarities of eBusiness problems and their solutions among different countries which permits analysis of the differences that are often defined by the national healthcare systems and their rules. Case studies from healthcare institutions and from suppliers in the US, the UK and Germany will illustrate the achievements, barriers and future plans, thus enabling newcomers to learn from previous experience.
Clinicians will gain significant insight by this book which demonstrates the interconnection between patient care processes and management issues at the level of medical supplies. The book also makes a plea for a multidisciplinary effort, to enable the right product to be procured for the right patient. As a rather new discipline, eBusiness in healthcare needs further scientific backing. Against this background, this book will not only provide answers but will also raise questions for future research. Managing change and innovation and establishing the critical mass for eBusiness in healthcare is a major undertaking. The aim of this book is to support this process.
