Supervision als Fortbildungsangebot für stellvertretende schulleiter

Supervision as further education of vice-headmasters Our offer of further education aims at an improvement of executive activities of viceheadmasters. With the help of their first experiences with our concept they’ll become acquainted with the various processes of change in schools and can use it as an opportunity to support them. That’s our contribution to the development of the executive personnel in the schools of Sachsen-Anhalt.     

Was kosten Kliniken? Zur Weiterentwicklung des Krankenhaussektors am Beispiel Berlins

The costs of hospitals. Developments of the German hospital sector evaluated in the case of Berlin This article illustrates the development of the German hospital sector evaluated in the case of the capital Berlin. Due to the difficult economic situation of the hospital sector after the reunification major reforms became unavoidable. Especially a reduction of the average days of stay per case created overcapacities of personell. But all the reforms which have been taken during the last years had to consider the major role of the hospital sector for the labour market of the city. On the one hand the article shows, that the reforms of the nineties have been successful also with regard to the important role for the labour market. On the other hand the restructuring of the hospital sector is not finished yet, there is still a need for further reforms.

Coaching für Führungskräfte im Krankenhaus Baustein einer Strategie zum Total Quality Management

Coaching of managers in hospitals as component of a total quality management strategy The author delineates the changed conditions of hospitals at the beginning of the new millenium. In order to be up to date with the growing challenges and the need for change a Total Quality Management (TQM) is necessary. This TQM sees the satisfaction of clients and of employees as crucial for all reorganization processes. The realization in everyday hospital life requires a total personnel development concept, with special regard to the managers and their specific needs for support by supervisors resp. coaches.     

A Measure of Dependence Between Two Compositions

We consider the problem of describing the correlation between two compositions. Using a bicompositional Dirichlet distribution, we calculate a joint correlation coefficient, based on the concept of information gain, between two compositions. Numerical values of the joint correlation coefficient are calculated for compositions of two and three components, respectively. We also present an estimator of the joint correlation coefficient for a sample from a bicompositional Dirichlet distribution. Two confidence intervals are presented and we examine their empirical confidence coefficients using a Monte Carlo study. Finally, we apply the estimator to a data set analysing the joint correlation between the 1967 and 1997, and the 1977 and 1997 compositions of the government gross domestic product for the 50 states of the USA and the District of Columbia.     

EXPLORA:content interpretation of data

Most approaches to applying knowledge-based techniques for data analyses concentrate on the context-independent statistical support. EXPLORA however is developed for the subject-specific interpretation with regard to the contents of the data to be analyzed (i.e. content interpretation). Therefore its knowledge base includes also the objects and semantic relations of the real system that produces the data. In this paper we describe the functional model representing the process of content interpretation, summarize the software architecture of the system and give some examples of its applications by pilot-users in survey analysis. EXPLORA addresses applications with data produced regularly which have to be analyzed in a routine way. The system systematically searches for statistical results (facts) to detect relations which possibly could be overlooked by a human analyst. On the other hand EXPLORA will help overcome the large bulk of information which today is usually still produced when presenting the data. Therefore a second knowledge process of content interpretation consists in discovering messages about the data by condensing the facts. Approaches for inductive generalization which have been developed for machine learning are utilized to identify common values of attributes of the objects to which the facts relate. At a later stage the system searches for interesting facts by applying redundancy rules and domaindependent selection rules. EXPLORA formulates the messages in terms of the domain, groups and orders them and even provides flexible navigations in the fact spaces.     

Estimating the prevalence of sensitive behaviour and cheating with a dual design for direct questioning and randomized response

Randomized response is a misclassification design to estimate the prevalence of sensitive behaviour. Respondents who do not follow the instructions of the design are considered to be cheating. A mixture model is proposed to estimate the prevalence of sensitive behaviour and cheating in the case of a dual sampling scheme with direct questioning and randomized response. The mixing weight is the probability of cheating, where cheating is modelled separately for direct questioning and randomized response. For Bayesian inference, Markov chain Monte Carlo sampling is applied to sample parameter values from the posterior. The model makes it possible to analyse dual sample scheme data in a unified way and to assess cheating for direct questions as well as for randomized response questions. The research is illustrated with randomized response data concerning violations of regulations for social benefit.
