Die Rolle von Psycholog/innen in den Medien

The role of psychologists in the mediaDiscribing the phenomena of frequently asking journalists the authors are trying to describe the social meaning of role-and functiontaking of the science of psychology in the public discussion. They are following the question whether it could be possible to publish scientific results without banalizing, taking part in voyerism and reprehensible emotion creating.     

Auswirkungen von Downsizing-Maßnahmen auf das organisationale Commitment der verbleibenden Mitarbeiter: Ein Vorher-Nachher-Vergleich

This study examines the consequences of downsizing efforts on organizational commitment, job satisfaction and work motivation of the remaining workforce (?survivors“) in a middle-sized telecommunication company. Employees were surveyed five months prior to the downsizing process (n=150) and eleven months thereafter (n=160). The assessment of organizational commitment was based on a questionnaire that was developed by Allen and Meyer (1990) within the scope of their three-components-model which includes affective, continuous and normative commitment. Although layoffs — as one part of the whole downsizing process — were not implemented in the investigated company, but only in a sister enterprise, which is part of the same holding, the affective commitment of employees towards their corporation dropped. On the other hand, the normative and the balanced commitment remained constant. Moreover, every second survivor showed reduced job satisfaction and work motivation. It should be noted that although the results of reorganisation and restructuring did not directly affect the employees of the investigated company, the emotional linkage between employees and employer was affected in a negative way. Additional findings from qualitative interviews suggest that restructuring was perceived to cause a crack in the prevailing corporate culture and the psychological contract. In addition, a deterioration of work conditions through work overload resulted.     

Entwicklung eines Programms zur kollegialen Introvisions-Supervision (KIS) für inner- und außerschulische Handlungsfelder

This article presents a new program of collegial supervision called ‘Collegial Introvision-Supervision’ (KIS). This phased program is based upon different concepts of collegial supervision (Pallasch, 1996; Spiess, 1996; Voss, 1996) and in particular on concepts of the TZI group supervision (Meister, 1996). The theoretical development is based on the ‘Integrative Introvision-Councelling’ and the practical foundation builds upon numerous supervision experiences of the author as well as upon tests in two projects of the professional education of teachers and social workers. A substantial aim of this new program is to find a procedure that optimises the perception of the factors taking part in the educational situation in order to make, based on that new perception, a new situational processing possible which allows a more appropriate educational reaction. The core of this change of perception is to reduce biographically caused aspects of a stress-generating estimation of the situation and to establish a calmer educational-acting mode.     

The finite-sample performance of robust unit root tests

This paper investigates the relative small sample performance of several robust unit root tests by means of a simulation study. It is confirmed that the traditional least-squares based Dickey-Fuller test has substantially lower power than several robust alternatives if the error distribution is fat-tailed while its power gain is small at the normal model. Particularly good results are achieved by a quasi-maximum likelihood test. However, all robust tests under consideration exhibit severe size distortions if the disturbances follow a skewed distribution. Moreover, under additive outliers, robust tests fail to produce stable sizes and good power properties. Consequently, the value of using robust unit root tests depends heavily of the type of nonnormality at hand.     

元人关于文学本体问题的思考

元代文论家从哲学高度对文学本体论进行了深入的探讨 ,形成了文学本于“理”和本于“气”两种文学本体论 ,这成为考察元代文学思潮不可回避的一个既复杂又重要的问题。元人对这一问题的探讨 ,也深化了对一些文学基本问题的认识。在元代 ,文学“气”本论占据了主导地位 ,而且形成了理论体系 ,这一理论体系在中国文论史上具有较高的理论价值

Consumer Selection of Food-Safety Information Sources

The aim of this study is to examine the preferences of consumers for different information sources when they have a question about food safety. On the basis of a nationally representative survey conducted in the Netherlands, five distinct consumer groups are identified that not only differ on the reported use of information sources but also regarding several personality characteristics and sociodemographic variables. The empirical results show that two-thirds of the consumers are selective in their use of information sources and prefer either institutional or social sources. So, multiple information-acquisition patterns exist among the general public. The study illustrates how these findings can help to develop effective risk communication strategies.

Robustness evaluation of multisite distributed schedule with perturbed virtual jobshops

A method for evaluating the robustness of medium term multisite distributed schedule is presented. The method of robustness evaluation is based on steps and tools associated with the conceptual model of a MultiSite Reactive Production Activity Control (MSR-PAC). The MSR-PAC makes it possible to study the sensitivity of the scheduled plans in presence of perturbations. These must be evaluated before being dispatched to the shop-floors. At present, to the best of the authors' knowledge, there is no means to make this evaluation in the distributed systems such as extended enterprise. The monitoring of errors is based on the discrepancy between the two flow-shape functions that model respectively the dynamics of the scheduled manufacturing orders and the state of the perturbed production. The MSR-PAC is based on a multisite agent system and on the monitoring of the perturbed virtual jobshops. The method can also be used for controlling short term distributed production activities.
