Feedback-Center zur Identifikation von Nachwuchsführungskräften Ein Instrument zwischen Entwicklung und Auswahl

Feedback-Center for identification of junior managers — an instrument between development and selection As an alternative to the classical Assessment-Center this article introduces the Feedback-Center as an instrument for diagnosis and support. The theoretical explanation of a project that was carried out in the course of an organizational development program in a middle-sized company is discussed. By social feedback, the participants of the Feedback-Center (in the case presented: the complete management of the company) get the chance to gain experience about themselves, to sort these different experiences and to plan and initiate steps to their own development, supported by their superiors as well as by the internal personnel manager and by the external consultants. The article describes the basic concept, the composition of the team of consultants and the practical realization of the Feedback-Center.     

Sparse regression techniques in low-dimensional survival data settings

In high-dimensional data settings, sparse model fits are desired, which can be obtained through shrinkage or boosting techniques. We investigate classical shrinkage techniques such as the lasso, which is theoretically known to be biased, new techniques that address this problem, such as elastic net and SCAD, and boosting technique CoxBoost and extensions of it, which allow to incorporate additional structure. To examine, whether these methods, that are designed for or frequently used in high-dimensional survival data analysis, provide sensible results in low-dimensional data settings as well, we consider the well known GBSG breast cancer data. In detail, we study the bias, stability and sparseness of these model fitting techniques via comparison to the maximum likelihood estimate and resampling, and their prediction performance via prediction error curve estimates.     

Ans?tze einer Produktionstheorie des Serienanlaufs

Over the last few decades, the number of production ramp-ups has risen substantially due to the increasingly fast pace of both technology and product life cycles. Up to now, however, the growing significance of ramp-ups for companies and their development has not been adequately addressed by business science from a theoretical perspective. We contribute by outlining a research map of production ramp-up from a theoretical perspective and identifying outstanding ramp-up characteristics: the initially lacking control over production quality, advancing experience effects, and the varying intensity of production as the operationalisation of the production ramp-up-policy. Existing models are then being analysed, as to how far they are able to reflect the so-sketched phenomenon of production ramp-up. By subsequently introducing a model of production ramp-up based on elements of these models, this study is to advance the development of a theory of production ramp-up. The proposed model builds upon a dynamisation of Gutenberg??s production model in order to explain the characteristic curve of production ramp-up.     

Wenn im Coaching die Paardynamik die Oberhand gewinnt

With the aid of two coaching cases it is illustrated how the consultation process can lead to a negative result if the consulters are trying to leave out their so called private live because they are afraid.

A Demographic Analysis of Registered Partnerships (legal same-sex unions): The Case of Norway

In 1993, Norway became the second country in the world to introduce registered partnerships. As with same-sex marriages, registered partnerships give the same rights and duties as marriages for opposite sex couples, with a few exceptions. The present article describes this ‘new’ demographic event based on Norwegian experiences. Compared to the number of new cases each year of opposite-sex marriages, registered partnerships amount to less than 1%. Gay partnerships are more common than lesbian partnerships, but the proportion of female partnerships has increased since the law came into force. In one out of five partnerships, one or both partners have been previously married to a person of the opposite sex. At the time they entered into the partnership, 24% of the women and 13 of the men had at least one child. When examining the registered partnerships entered into in Norway between 1993 and 2001 we estimated the probability of divorce to be 16% after six years. We also carried out a multivariate analysis of the divorce risk and found that the divorce risk for female partnerships is double that of the risk for male partnerships. Another high risk group is partnerships between a Norwegian and a person from a non-Nordic country.Noack T., Seierstad A. and Weedon-Fekjær H., 2005, A Demographic Analysis of Registered Partnerships (legal same-sex unions): The Case of Norway, European Journal of Population, 21: 89–109.Noack T., Seierstad A. and Weedon-Fekjær H., 2005, A Demographic Analysis of Registered Partnerships (legal same-sex unions): The Case of Norway, European Journal of Population, 21: 89–109.     

Measuring hand movements

Hand movements were classified into speech illustrators, body manipulators, and actions which convey precise symbolic information. The behavioral code noted whether the action involved the left, right, or both hands, and the manipulator code also included the part of the body manipulated. The application of this code to videotapes of conversations provided data to examine a number of methodological issues. Reliability was inspected in a number of ways; each showed high intercoder agreement. Little redundancy was found among the various hand measures, although scores for the frequency of an activity and for the duration of an activity were highly intercorrelated for most classes of hand actions. An economical method for coding hand activity was compared with the standard, more time-consuming method. Similar results were obtained, although the economical method appeared to be more vulnerable to measurement error.This research was supported by a grant from NIMH, MH 11976.
