Emergenz und Reduktion

The micro-macro-link is a common problem in nearly every scientific field. In contemporary philosophy of mind a new concept of emergence has been developed which could also be useful for sociology. After a brief overview of the debate in the field of philosophy of mind, three different answers to the micro-macro problem are being distinguished and then transferred to sociology: an eliminative (e.g. R. Collins), a reductionist (e.g. rational choice theories) and a non-reductive answer based on the concept of emergence (e.g. Emile Durkheim, and, partly, N. Luhmann). Using the argument of “multiple realization” the article argues for a “conceptual dualism”.     

A Note on the Separability Principle in Economies with Single-Peaked Preferences

We consider the problem of allocating an infinitely divisible commodity among a group of agents with single-peaked preferences. A rule that has played a central role in the analysis of the problem is the so-called uniform rule. Chun (2001) proves that the uniform rule is the only rule satisfying Pareto optimality, no-envy, separability, and Ω-continuity. We obtain an alternative characterization by using a weak replication-invariance condition, called duplication-invariance, instead of Ω-continuity. Furthermore, we prove that the equal division lower bound and separability imply no-envy. Using this result, we strengthen one of Chun’s (2001) characterizations of the uniform rule by showing that the uniform rule is the only rule satisfying Pareto optimality, the equal division lower bound, separability, and either Ω-continuity or duplication-invariance.     

Graduate education and the academic job market

This article reviews actual and projected college enrollments, and demand for faculty, during the 1970s, 1980s and 1990s. Although new PhDs were finding satisfying employment in government, business and industry, many graduate programs in sociology were slow to expand their academically-oriented curricula to include a concern with sociological practice when the academic job market contracted in the late 1970s. This suggests that departments may quickly reestablish narrowly focused curricula once the academic market expands again in the late 1990s. As a result, the multiple career options currently available to graduate students again may be replaced by an exclusive focus on research careers in academia.     

Non-engagement of Mid-aged and Elderly Residents in Rural Civic Livability Initiatives

In the context of public budget cuts and rural areas facing depopulation and aging, local governments increasingly encourage citizen engagement in addressing local livability issues. This paper examines the non-engagement of mid-aged and elderly residents (45+ years old) in civic initiatives that intend to improve the livability of their community. We focus on residents of depopulating rural areas in the North Netherlands. We compare their engagement with the behavior of residents in other, not depopulating, rural areas, and urban areas. Using logistic statistical analyses, we found that the majority of the aging residents did not engage in civic livability initiatives during the past two years, and one-third of this group had no intention to do so in the future. In all areas, the main reasons for non-engagement were that residents had other priorities, felt not capable of engaging, or felt that the responsibility for local livability belonged to the local government. Furthermore, it appeared that non-engagement was predominantly explained by the unwillingness to engage, rather than by specific motivations or lacking abilities.     

Not just hot air: normative codes of conduct induce cooperative behavior

The shirking incentives arising within team production are in general counteracted by monitoring and sanctioning. However, these mechanisms are usually associated with high monitoring costs and cannot be applied to all parts of the production process. In a laboratory experiment we analyze the impact of less costly elements of organizational structure, such as normative codes of conduct and screening tests, on team production efficiency. We find that more allusions to a firm context lead to higher contributions. In particular, codes of conduct significantly increase cooperation and at the same time reduce free-riding behavior. Our study provides empirical evidence that normative codes of conduct are an effective means of increasing team production efficiency.

“She Got Spoilt”: Perceptions of Victims of Child Sexual Abuse in Ghana

ABSTRACT

International research has commented on social stigma as a key reason for nondisclosure of child sexual abuse. However, the actual components of this social stigma frequently remain unexplored. The present study deals with perceptions of consequences of child sexual abuse among professionals and laypeople in Ghana (N = 44), employing a bystander perspective. As a qualitative study using a grounded theory framework, it considers these consequences in light of their underlying beliefs about child and adolescent development, particularly in relation to gender-based expectations placed on girls and boys. Consequences of child sexual abuse could be divided into sexual health consequences, beliefs about “destroyed innocence” and beliefs about a “destroyed future,” which were strongly related to the sexual nature of the violence perpetrated. These perceived consequences of child sexual abuse hold implications for what surviving child sexual abuse means on a social level. Implications for practice are discussed on the basis of the data analysis.     

TZI: Das ist der Knochen, unsere Themen sind das Fleisch

The first author has been running a ?TZI and self-experience“ workshop for eight years. Participants were undergraduates following educational studies with a family and leisure education bias. The authors try to systematically evaluate this course and to discover structures. A relatively standardized framework with a set content proved to be successful. Added to it are personally relevant topics based on biographical and current experience, questions evolving from the ongoing interaction in the group and work with individual persons in front of the group. How to handle the theme is discussed. Typical and particular difficulties and how to cope with them are presented.     

Modelling human immunodeficiency virus ribonucleic acid levels with finite mixtures for censored longitudinal data

The measurement of human immunodeficiency virus ribonucleic acid levels over time leads to censored longitudinal data. Suitable models for dynamic modelling of these levels need to take this data characteristic into account. If groups of patients with different developments of the levels over time are suspected the model class of finite mixtures of mixed effects models with censored data is required. We describe the model specification and derive the estimation with a suitable expectation-maximization algorithm. We propose a convenient implementation using closed form formulae for the expected mean and variance of the truncated multivariate distribution. Only efficient evaluation of the cumulative multivariate normal distribution function is required. Model selection as well as methods for inference are discussed. The application is demonstrated on the clinical trial ACTG 315 data.
