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.     

Anreizsysteme und Unternehmensethik

The article analyses the structuring of incentive systems from a business ethics point of view. The focus is on examining the impact of different types of social preferences on wage compensation. Besides the structuring of incentive systems, especially the effects of different types of social preferences on firm profits are analyzed. The paper systematizes important determinants for the impact of social preferences on the structure of the incentive system as well as firm profitability and provides an overview over the literature employing formal models based on a possibly general modeling approach.     

Beneficial safety decreases

We construct a model of rational choice under risk with biased risk judgement. On its basis, we argue that sometimes, a regulator aiming at maximising social welfare should affect the environment in such a way that it becomes ‘less safe’ in common perception. More specifically, we introduce a bias into each agent’s choice of optimal risk levels: consequently, in certain environments, agents choose a behaviour that realises higher risks than intended. Individuals incur a welfare loss through this bias. We show that by deteriorating the environment, the regulator can motivate individuals to choose behaviour that is less biased, and hence realises risk levels closer to what individuals intended. We formally investigate the conditions under which such a Beneficial Safety Decrease—i.e. a deteriorating intervention that has a positive welfare effect—exists. Finally, we discuss three applications of our model.     

Variance bounds for estimators in autoregressive models with constraints

We consider nonlinear and heteroscedastic autoregressive models whose residuals are martingale increments with conditional distributions that fulfil certain constraints. We treat two classes of constraints: residuals depending on the past through some function of the past observations only, and residuals that are invariant under some finite group of transformations. We determine the efficient influence function for estimators of the autoregressive parameter in such models, calculate variance bounds, discuss information gains, and suggest how to construct efficient estimators. Without constraints, efficient estimators can be given by weighted least squares estimators. With the constraints considered here, efficient estimators are obtained differently, as one-step improvements of some initial estimator, similarly as in autoregressive models with independent increments.
