„Unkündbar und nun?“ Lebensziel oder Schicksalsschlag – Chancen für eine faire Trennungskultur in der öffentlichen Verwaltung

Job security is seen as a very high value by employees regarding their professional objectives. Especially for employees in public service that secure professional status is one of their main reasons for working in public servance. Therefore, any dismissal may have severe negative effects on health of the employees and also negative effects on the image of the employer. From their perspective, an outplacement program could be an expedient element within the employee-life-cycle (recruiting—retention—exit/outplacement). A fair culture of separation in the organizational context in public sector which is accompanied by an outplacement program can give new perspectives to the employees and strengthen the image of the employer. An interview study with clients of an outplacement consultation will be mentioned. The participants were asked about their expectations and experiences with the consultation. Basically, the results clearly show that the consultant has a tremendous importance and is thus one of the most important success factors. If he or she meets the needs of the client, he or she works up the separation and promotes the confidence of his clients, nothing stands in the way of a successful consultation.     

Kooperative Resilienz – ein soziotechnischer Ansatz durch Kooperationstechnologien im KrisenmanagementCooperative resilience – a sociotechnical approach through cooperation technologies in crisis management

Whilst the concept of resilience in engineering is mainly focussed on the availability of technical systems, we rather see resilience as socio-technical construct and show opportunities to encourage cooperative resilience with the help of cooperation technologies. After a general definition of resilience in our application field of emergency management and in the context of cooperative structures, we present our methodology and the developed cooperation technologies. They address the collaboration of diverse players (such as police, fire department, and citizen) in major emergencies. Finally we discuss the input of this technology for cooperative resilience to overcome crises of cooperation with the help of adaptability to modified realities by means of cooperation technology.     

European Business Cycles: New Indices and Their Synchronicity

This article presents a new business cycle index that allows for cycle-to-cycle comparisons of the depth of recessions within a country, cross-country comparisons of business cycle correlation, and simple aggregation to arrive at a measure of a European business cycle. The data augmentation implied by Gibbs sampling generates posterior distributions for a latent coincident business cycle index. Subsample correlations between an aggregated "Europe" index and the national business cycle indices from France, Germany, and Italy are consistent with the claim that the European economies are becoming more harmonized.     

Easy Sport: Research and Relevance

This paper is an analysis of the Final Report of the Commission on the Review of the National Policy Toward Gambling. After discussing the origins and political environment of the Commission, the paper focuses on the relationship between the Commission's recommendations and the results of its own research. The author argues that the research was used only where it fitted the Commission's views and was ignored where it did not. The paper concludes with a discussion of the structural factors that led to this outcome.
Criticizing the banal and unsubstantiated policy views of public commissions is easy sport… I do so only to make a simple point: public commissions, on the record, have either made no use of social science… made some use but in ways irrelevant to its policy conclusions…, or made use of relevant but unconvincing research. (Wilson, 1978)     

A parsimonious multivariate poisson model for market basket analysis

Intensified research on multivariate Poisson models offers new opportunities for the analysis of purchase quantities in market basket data. The investigation of positive or negative correlations in quantity decisions among product categories facilitates a deeper understanding of consumer purchase behavior. The applied multivariate log-normal Poisson model introduces interdependencies between categories with multivariate normal-distributed latent effects by means of a covariance matrix. As the size of this covariance matrix depends on the number of categories in the model, its ation may become tedious. Furthermore, we assume that quantity decisions do not interact for all pairs of categories. That is why we propose to use covariance selection to derive a parsimonious representation of the correlation structure. For two market basket data sets, we show that the vast majority of off-diagonal elements in the covariance matrix are irrelevant. For a data set with product categories, the model with a partly restricted covariance matrix achieves a better fit to the holdout data than the model with full covariance matrix. For a data set with subcategories of the broader category beverage, the proposed model with restricted covariance outperforms the model with full covariance matrix even on the calibration data. We conclude that interactions of quantity decisions are overall the exception, even for complements-in-use.     

„Wir mussten Coaching erstmal salonfähig machen“

In this study coaching culture is defined as a part of organizational culture that reflects the patterns of assumptions and actions concerning coaching, as well as the perception and evaluation of results and modes of effects. A qualitative study with 15 experts from six large companies revealed that positive and negative cultures concerning coaching can be differentiated. The results show a trend towards a positive culture, which needs active support. It is assumed that the coaching culture is a relevant impact factor for the efficacy of coaching.     

Sex differences in the use of psychiatric outpatient facilities

Previous research has shown that both symptoms and sociocultural factors are related to use of psychiatric outpatient facilities. However, the utility of using treatment rates from these facilities to make etiological inferences depends on whether sociocultural effects on utilization are trivial or substantial. In this paper data are presented for one such inference, that women are more in need of treatment than men. We find that observed sex differences in the use of a student psychiatric clinic are due both to differential propensities to seek help for problems and also to differential numbers of problems, both of which are higher among women than men. However, the differential propensity to seek help is found to be by far the more important of these two effects.     

Negative Effekte von Coaching und ihre Ursachen aus der Perspektive der Organisation

Negative effects of business-coaching and their causes have been barely addressed in research so far. In this qualitative pilot-study the perspective of organisations is being addressed for the first time. The most frequently stated negative effects were a too strong development of clients in the perception of the interviewees, a termination of the job by clients, a lack of sustainability of the results and an insufficient return on investment. As influencing factors e.?g. the attitude of the organisation towards coaching, imprecise clarification of coaching assignments, lack of motivation of the client or the working methods of coaches were reported.     

Computer Use and Employment Status of Older Workers — An Analysis Based on Individual Data

Abstract. This paper analyses the determinants of computer use by male employees and estimates the impact of computer use on the employment status for older workers, based on individual data from the German Socio‐Economic Panel. In line with previous research on the diffusion of new technologies, a strong and negative relationship between the age of workers and computer use is found. The correlation of educational level and occupational status on computer use is significantly positive. However, the estimated impact of computer use on the change in employment status of older workers becomes insignificant when controlling for individual and firm‐specific characteristics.     

Optimal designs for non-competitive enzyme inhibition kinetic models

In this paper, we present a new method for determining optimal designs for enzyme inhibition kinetic models, which are used to model the influence of the concentration of a substrate and an inhibition on the velocity of a reaction. The approach uses a nonlinear transformation of the vector of predictors such that the model in the new coordinates is given by an incomplete response surface model. Although there exist no explicit solutions of the optimal design problem for incomplete response surface models so far, the corresponding design problem in the new coordinates is substantially more transparent, such that explicit or numerical solutions can be determined more easily. The designs for the original problem can finally be found by an inverse transformation of the optimal designs determined for the response surface model. We illustrate the method determining explicit solutions for the D-optimal design and for the optimal design problem for estimating the individual coefficients in a non-competitive enzyme inhibition kinetic model.
