Violence in street culture: cross-cultural comparison of youth groups and criminal gangs

Violence is a widespread phenomenon in juvenile street culture. But the questions of whether this relationship is a deterministic one, and if not, which are the contributing factors, are largely unanswered. This article focuses on the role of public space, starting with a comparison of the meaning of deviant behavior and crime in street culture in Brazil, Russia, and Germany. Focusing on street culture norms and their relevance for youth groups in everyday life, the author shows that there are worldwide similarities, and these are most likely to be seen in disadvantaged neighborhoods. The article deals not only with the question of how people act in conflicts but also focuses on a social order in which the reputation of men is based mainly on questions of masculinity, honor, and power expressed through aggressive behavior. The results are based on more than one hundred semistructured qualitative interviews with street culture youth, prison inmates, adult family members, social workers, police, and researchers that were conducted in recent years in the three countries.The study also describes a typology of conflict behavior among male street culture youth that helps in understanding why even juveniles who were socialized in the milieu of the street culture can reject violence and do not have to turn to violence in all conflicts. The article examines the similarities in the reasons for violence and fear of violence, as well as the differences in frequency and intensity between violent countries (such as Brazil and the Russian Federation) and less violent countries (for example, Germany).     

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?     

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.     

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.

Physical and Mental Health Correlates of Self-Efficacy in Dementia Family Caregivers

This study examined whether self-efficacy for controlling upsetting caregiving thoughts would longitudinally predict mental and physical health as well as utilization of psychotropic medications in help-seeking dementia family caregivers (N = 53). Positive associations were found between self-efficacy and self-reported mental health and physical health subscales of the Short Form Health Questionnaire-12, and negative correlations were found between self-efficacy for controlling upsetting thoughts about caregiving and the number of psychotropic medications being utilized both cross-sectionally and longitudinally. These results suggest that self-efficacy for controlling upsetting thoughts may be a fruitful target area for further intervention research with dementia family caregivers.     

Die Abgeltungsteuer auf Kursgewinne und der Steuerstundungseffekt in der Unternehmensbewertung

In Germany capital gains have to be taxed independently of the holding period, according to the withholding tax regulations. Nevertheless, investors can initially avoid taxation by not realizing capital gains. Then, taxes are postponed into the future. Thereby investors can make use of an interest-free tax loan (tax deferral). Equally beneficial would be the immediate realization of negative capital gains, if this leads to reduced taxes by balancing these losses against other gains. The potential use of interest-free tax loans leads to the necessity of making assumptions on the investors?? strategy with respect to liquidation when it comes to business valuation based on discounting future after-tax payments towards investors (DCF-methods). It will be shown how much firm value depends on these assumptions by taking alternative, inflexible and flexible strategies of investors into account. Our considerations generate a lower and an upper bound for the firm value, and easier to calculate medium values. The calculations are illustrated by a numerical example which is also the subject of a comparative static analysis.     

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.     

The new ‘hidden abode’: reflections on value and labour in the new economy

In a pivotal section of Capital, volume 1, Marx (1976 : 279) notes that, in order to understand the capitalist production of value, we must descend into the ‘hidden abode of production’: the site of the labour process conducted within an employment relationship. In this paper we argue that by remaining wedded to an analysis of labour that is confined to the employment relationship, Labour Process Theory (LPT) has missed a fundamental shift in the location of value production in contemporary capitalism. We examine this shift through the work of Autonomist Marxists like Hardt and Negri, Lazaratto and Arvidsson, who offer theoretical leverage to prize open a new ‘hidden abode’ outside employment, for example in the ‘production of organization’ and in consumption. Although they can open up this new ‘hidden abode’, without LPT's fine‐grained analysis of control/resistance, indeterminacy and structured antagonism, these theorists risk succumbing to empirically naive claims about the ‘new economy’. Through developing an expanded conception of a ‘new hidden abode’ of production, the paper demarcates an analytical space in which both LPT and Autonomist Marxism can expand and develop their understanding of labour and value production in today's economy.
