Inferences concerning interpersonal choices given anonymously

It may be difficult or impossible to make a reliable empirical investigation of an unknown network of interpersonal choices or contacts if these are in some respect sensitive for the individuals involved. We consider how choice data given anonymously can be used to reveal various features of the network. Using tools from statistical decision theory and information theory we can determine risks and capacities of disclosing choice data, the graph structure of choice data and its numbers of loops and mutuals. We give some general results, illustrate the combinatorial complexity of the problem and comment upon the computational difficulties.     

Projective (2n,n,λ,1)-designs

A projective (2n,n,λ,1)-design is a set $\text{D}$ of n element subsets (called blocks) of a 2n-element set V having the properties that each element of V is a member of λ blocks and every two blocks have a non-empty intersection. This paper establishes existence and non-existence results for various projective (2n,n,λ,1)-designs and their subdesigns.     

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.     

Der Insolvenzprozess und die Eigenverwaltung in der Insolvenz auf Basis unterschiedlicher Theoriekonzepte

Zusammenfassung  Der Beitrag erkl?rt einerseits die Notwendigkeit eines durch Gesetz geregelten Verfahrens zur Insolvenzabwicklung mittels betriebswirtschaftlicher Grundlagentheorien. Andererseits werden dieselben Grundlagentheorien genutzt, um die unterschiedlichen sich ver?ndernden Machtstrukturen, die oft gegens?tzlichen Interessen von Stakeholdern, die Kosten des Insolvenzprozesses sowie deren Dynamik im Rahmen des vierphasigen Insolvenzprozesses (vor Insolvenzanmeldung, nach Antragstellung, nach Er?ffnung, nach Abschluss des Verfahrens) eines Not leidenden Unternehmens besser veranschaulichen zu k?nnen. Der besondere Schwerpunkt wird hierbei auf das Verfahren in Eigenverwaltung, das hei?t mit eigenem Management, gelegt.

The bankruptcy process and the self-administration in the bankruptcy proceedings

Summary  This article explains on one hand the necessity of a legally fixed process for the bankruptcy proceedings with basic economic theories. On the other hand, the same theories are used to demonstrate the changing power structures, the often different interests of stakeholders, the costs of the bankruptcy proceedings as well as its dynamics during the four bankruptcy phases (before the filing, after the filing, after opening and after closing) of the bankruptcy process. The focus of this article lies hereby on bankruptcy proceedings in self-administration which means that the management stays on duty.

Gedanken zur Gestaltung einer professionellen Beratungsausbildung

Considerations on the design of a professional education of counselorsSome of the recently published articles about supervision-professionalizing are reflecting only sociological or psychological conceptions in order to describe and analyze professionality. In this article the authors discuss some of the mostly neglected points of view out of pedagogic and microsociologic professionalization-research (professional self, researching attitude). The existing requests of competence for supervisors are examined in order to test their teaching ability. Furthermore the content designs and didactic strategies for future counselor’s education are considered.     

Flexible Copula Density Estimation with Penalized Hierarchical B‐splines

The paper introduces a new method for flexible spline fitting for copula density estimation. Spline coefficients are penalized to achieve a smooth fit. To weaken the curse of dimensionality, instead of a full tensor spline basis, a reduced tensor product based on so called sparse grids (Notes Numer. Fluid Mech. Multidiscip. Des., 31, 1991, 241‐251) is used. To achieve uniform margins of the copula density, linear constraints are placed on the spline coefficients, and quadratic programming is used to fit the model. Simulations and practical examples accompany the presentation.     

Being,feeling and acting: A qualitative study of Swedish home-help care recipients' understandings of dependence and independence

This article contributes to the debate on dependence and independence through a study of how a group of 29 cognitively healthy Swedish home-help care recipients between the ages of 77 and 93 perceive their situation. Two overall themes with regards to how the constructs of dependence and independence are understood were found. One of them concerns how being in need of help can be justified (i.e. the why of receiving help) and the other how the very situation of being in need of help and care can be regarded (i.e. the how of receiving help). The study reveals a clear distinction between receiving help and care and feeling dependent, as well as between receiving help and care and being able to remain an active agent. On the basis of these findings we argue for the fruitfulness of distinguishing between ‘being’, ‘feeling’ and ‘acting’ as aspects of dependence and independence.
