A macroeconomic potential describing structural change of the economy

For the purpose of describing change in an economy's structure, and addressing issues of transformation, the notion of a time-dependent macroeconomic potential function is introduced. It penalizes deviations from equilibrium (entrepreneurial error) and induces moves toward equilibrium. Thus, from the concept of a potential function is derived the concept of short-term and long-term change forces. We focus here on the long-term structural changes of an economy as distinct from short-term cyclical variations, and we represent economic transformations as phase-transitions between monostable and ambiguous bistable states of the economy. One important feature of the potential function approach is that the parameter of the potential can be determined from empirical data. In particular, the parameters can be regressed for input variables. Hence, a relationship has been established between the structural change force and a set of input variables, some of which are controlled in part by either public or private sector agents. The method has been applied to West German and United States industry data for 1950–1980.     

Bargaining with Incomplete information an axiomatic approach

Within this paper we consider a model of Nash bargaining with incomplete information. In particular, we focus on fee games, which are a natural generalization of side payment games in the context of incomplete information. For a specific class of fee games we provide two axiomatic approaches in order to establish the Expected Contract Value, which is a version of the Nash bargaining solution.     

A model to support the assessment of subjective probabilities

Conclusions The purpose of this article has been to provide a new method for the determination of subjective probabilities. The kind of support which is suggested for the assessment process has several interesting properties. Constructed in accordance with the Savage theory the procedure considers a preference structure on the space of the possible actions A or on a suitably chosen space A ^* as its basis. This structure will be attained by pairwise comparison of the elements a _i A (or a _i ^*A ^*). It may be incomplete and inconsistent. A linear programming approach will use this information to derive numerical probabilities which are in accordance with the stated preference judgments. Therefore, it avoids the difficulties which arise when the judge has to assign the numerical values to the possible states of nature. On the other hand, this method presents the advantage of taking into consideration all relevant a priori information because of its systematic judgment process. Another important element is given by the use of coefficients which express the judge's confidence in the stated comparisons. Further relevance is added to the procedure by the relatively small consumption of time and work to report the judgments even in complex situations, and by the renunciation of any methodological knowledge on the part of the judges.This study was financed by a research grant of the Deutsche Forschungsgemeinschaft (DFG).     

Paul Lazarsfelds typologische Methode und die Grounded Theory. Generierung und Qualität von Typologien

The following article deals with the connections between the typological method proposed by Paul Lazarsfeld and the Grounded Theory. The question how good typologies in qualitative social research can be constructed will be raised. It will be argued that formal criteria are necessary but not sufficient in judging whether a typology is good. The typology also needs to be relevant in its contents. The article will show that the Grounded Theory can help to solve this problem by creating attributes for typology construction analogous to the Grounded Theory's process that is used to generate theory. On the other hand, Lazarsfeld's concept of “attribute space” can be of assistance for the process of “theoretical sampling” proposed by the Grounded Theory by providing a systematic scheme for selecting the cases to be studied. The article will conclude with an empirical example illustrating the issues mentioned above.     

Composite screener for androgen deficiency related to the aging males’ symptoms scale

Objective.?Methodological characteristics of the Aging Males’ Symptoms (AMS) scale point towards a high standard measurement and comparison of health-related quality of life (HRQoL) over time or intervention. However, the scale was neither developed nor standardized as a screening instrument for androgen deficiency.

Methods.?Data of the Austrian ANDROX study suggested to develop a composite screener for androgen deficiency based on AMS, age, and BMI, to determine sensitivity and specificity to detect low total testosterone (TT) levels. The findings were compared with those of an independent sample of urological patients with suspicion of androgen deficiency (AD) from Germany (n = 803).

Results.?A graphical solution for a composite-screening tool was proposed, with three levels of suspicion for AD: positive screening result (high suspicion), equivocal result, and negative screening result (no suspicion, AD unlikely). The percentage of TT values < 4 ng/ml were 18.7%, 40.7% and 58.8% in the three categories: negative, equivocal and positive, respectively. The findings were confirmed in the independent German sample. In both instances, neither sensitivity nor specificity was very high, i.e., between about 50% and 75%.

Conclusion.?The results of the development and initial validation of the new screener are promising. Further information, and experience from the practice, is needed to confirm or refute the hypothesis that this screener is a useful tool for medical practice.     

Affective and aesthetic dimensions of contemporary social movements in South West England

The paper examines contemporary social movement activity within South West England. It is argued that much social movement analysis has been too nation‐state orientated, that it has too readily framed diverse contemporary practices within a narrow, politically reductive and instrumentally rational frame. Increasingly, aesthetic and affective dimensions of everyday life must be examined if any coherent theoretical account of such activity is to be offered. Altering relations between states and their citizens in a global age and the emergence of an extended civil society are linked to a weakening of the capacity of nation states to manage identity formation. A series of excursuses link theoretical analysis of the expressive dimensions of the region's social movement activity, to these more extended global transformations.     

Zentrum und Peripherie im globalen Wissenschaftssystem

We use an experimental design to analyse the effect of symbolic capital of a nation’s higher education system and of single universities on students’ opportunities for international mobility. Fake applications of international doctoral students were sent to German sociology professors, who were asked to serve as supervisors during a research visit in Germany. Our fake applicants come from four different universities: Yale, Pennsylvania State University, National University Singapore, and Vietnam National University Hanoi. The results show that applicants from both US institutions get more positive, more informative and more personal feedback than applicants from Singapore and Vietnam. Moreover, the symbolic capital of a university seems more important than the quality of a specific department, which is problematic in normative terms.     

Prosoziales Arbeitsverhalten: Entwicklung und Überprüfung eines Messinstruments zur Erfassung des freiwilligen Arbeitsengagements

A German version of the Organizational Citizenship Behavior Questionnaire (GOCBQ) is developed and tested. Study 1 was conducted with 150 students working together in 39 project groups. The results show that the internal consistency and test-retest-reliability of the GOCBQ are good. Moreover, the GOCBQ measures a general altruism orientation which can be interpreted as a stable trait. The GOCBQ does neither correlate substantially with demographical variables nor with extroversion or neuroticism. Instead, substantial correlations are registered with mood and group atmosphere. In study 2 results from study 1 were cross-validated with data from 128 voluntary and professional helpers, in study 3 with data from 43 professionals. Implications for future research and applications in working life are discussed.
