Who is Who? Die Sozialstruktur der Soziologie-Professorenschaft in Deutschland

Against the background of existing patterns of recruitment within academics the article deals with the socio-structural composition of the professors in the field of sociology. The basis is a full survey of professors at departments of sociology at German universities and a number of selected research institutes. The parameters of interest are the share of female professors, the share of foreign professors, the social background of professors in terms of coming from East or West Germany and the age distribution. In order to capture changes over time, we differentiate the data according to birth cohorts. All in all with the exception of the feminization of the profession we find a great structural stability of the composition of sociology professors, which indicates the ongoing dominance of specific pattern of recruitment. In particular the inclusion of East Germans and the internationalization of the professorial personal have not advanced.     

Primäre und sekundäre Effekte der sozialen Herkunft beim Übergang in die Hochschulbildung

Following Boudon social disparities at educational transitions can be linked to primary and secondary effects of social origin. Whereas primary effects describe social differentials in scholastic performance, secondary effects represent social differences in educational choices that are independent of performance. We use four panel surveys of graduate cohorts that have obtained eligibility for higher education between 1983 and 1999, provided by the German Higher Education Information System (HIS). By applying counterfactual decomposition methods we estimate the relative importance of primary and secondary effects at the transition to tertiary education. Our results indicate that secondary effects are the main driving force in the creation of social disparities at the transition to tertiary education, accounting for more than 80% of the differential between service class and working class offspring. Particularly financial aspects connected to the choice of post-secondary alternatives, interest in academic work and the type of Abitur degree can explain these effects. Furthermore, even though we observe a small increase in social selectivities at the transition to higher education, the relative importance of primary and secondary effects does not change within our observation period.     

Non-linear mixed logit

We develop an extension of the familiar linear mixed logit model to allow for the direct estimation of parametric non-linear functions defined over structural parameters. Classic applications include the estimation of coefficients of utility functions to characterize risk attitudes and discounting functions to characterize impatience. There are several unexpected benefits of this extension, apart from the ability to directly estimate structural parameters of theoretical interest.     

Selections and social selectivity on the academic track: A life-course analysis of educational attainment in Germany

Graduating from university is just the final step of an extended educational career. Sociological transition research has revealed that final educational attainment must be understood as the result of a sequence of successive decisions. With regard to graduation from university, one has to take into account that upper secondary school qualifications are required for enrolling in the first place, and in Germany, the decision for this kind of schooling is at a much earlier age. So where on the long way to the university degree does Germany ‘lose’ its potential academics and in particular its lower class children?     

RDELA—a Delaunay-triangulation-based, location and covariance estimator with high breakdown point

We propose an approach that utilizes the Delaunay triangulation to identify a robust/outlier-free subsample. Given that the data structure of the non-outlying points is convex (e.g. of elliptical shape), this subsample can then be used to give a robust estimation of location and scatter (by applying the classical mean and covariance). The estimators derived from our approach are shown to have a high breakdown point. In addition, we provide a diagnostic plot to expand the initial subset in a data-driven way, further increasing the estimators’ efficiency.     

Appeals to social norms as policy instruments to address consumption externalities

We consider appeals to social norms as a policy instrument to address consumption externalities. We explore whether appeals to social norms can be an efficient policy instrument and compare the efficiency of such appeals to the efficiency of taxation in addressing consumption externalities. We find that when the existing norm helps to shift consumption towards the socially optimal level of consumption, taxation welfare dominates appeals to social norms as a policy tool. While previous studies have found that economic instruments are superior to information in other contexts, we arrive at a different conclusion for situations where the norm shifts behavior away from what is socially optimal. In such cases appeals to social norms can be a better policy instrument than taxation.     

Is the Relationship Between Pornography Consumption Frequency and Lower Sexual Satisfaction Curvilinear? Results From England and Germany

Several studies using different methods have found that pornography consumption is associated with lower sexual satisfaction. The language used by media-effects scholars in discussions of this association implies an expectation that lowered satisfaction is primarily due to frequent—but not infrequent—consumption. Actual analyses, however, have assumed linearity. Linear analyses presuppose that for each increase in the frequency of pornography consumption there is a correspondingly equivalent decrease in sexual satisfaction. The present brief report explored the possibility that the association is curvilinear. Survey data from two studies of heterosexual adults, one conducted in England and the other in Germany, were employed. Results were parallel in each country and were not moderated by gender. Quadratic analysis indicated a curvilinear relationship, in the form of a predominantly negative, concave downward curve. Simple slope analyses suggested that when the frequency of consumption reaches once a month, sexual satisfaction begins to decrease, and that the magnitude of the decrease becomes larger with each increase in the frequency of consumption. The observational nature of the data employed precludes any causal inferences. However, if an effects perspective was adopted, these results would suggest that low rates of pornography consumption have no impact on sexual satisfaction and that adverse effects initiate only after consumption reaches a certain frequency.     

Constrained Monotonicity and the Measurement of Power

In this paper we will discuss constraints on the number of (non-dummy) players and on the distribution of votes such that local monotonicity is satisfied for the Public Good Index. These results are compared to properties which are related to constraints on the redistribution of votes (such as implied by global monotonicity). The discussion shows that monotonicity is not a straightforward criterion of classification for power measures.
