The Contours and Correlates of Informal Work in Rural Pennsylvania*

Abstract Social scientists have increasingly come to recognize the informal economy as a prominent and permanent structural feature of modern society. Rural sociologists have made a considerable contribution to this literature, demonstrating informal work to factor prominently in the livelihood strategies of rural Americans. Despite this scholarly attention significant gaps persist in our understanding of the informal economy. Drawing on data from a survey of family households in nonmetropolitan Pennsylvania, this paper examines the contours and correlates of informal work. The results make a strong case that participation in informal work is widespread and most often combined with formal work as a household livelihood strategy. While income is not found to be a significant correlate of informal work, it is found to influence the reasons cited for participation. Important correlates of informal work are identified and differences in the factors associated with informal work done to generate income (cash or in‐kind) versus savings are revealed.     

Extended voting measures

This paper extends a number of voting measures used to quantify voting power. The extension is based on the recognition that individuals sometimes vote in coalitions. This observation gives rise to a statistical model which considers past voting patterns of subsets of eligible voters. The model is then used to obtain estimates of the probabilities of all voting combinations from which empirical measures are calculated. The calculation of the estimated probabilities may involve high-dimensional integrations. An example is given based on past decisions arising from the Supreme Court of Canada.     

Psychometric Evaluation of the Affect Regulation Checklist: Clinical and Community Samples,Parent-Reports and Youth Self-Reports

The Affect Regulation Checklist (ARC) was designed to capture affect dysregulation, suppression, and reflection. Importantly, affect dysregulation has been established as a transdiagnostic mechanism underpinning many forms of psychopathology. We tested the ARC psychometric properties across clinical and community samples and through both parent-report and youth self-report information. Clinical sample: Participants included parents (n = 814; M_age = 43.86) and their child (n = 608; M_age = 13.98). Community sample: Participants included independent samples of parents (n = 578; M_age = 45.12) and youth (n = 809; M_age = 15.67). Exploratory structural equation modeling supported a three-factor structure across samples and informants. Dysregulation was positively associated with all forms of psychopathology. In general, suppression was positively associated with many forms of psychopathology, and reflection was negatively associated with externalizing problems and positively associated with internalizing problems.     

Truly embodied sociology: marrying the social and the biological?

This paper explores the relation between sociology and biology through an examination of issues relating to the sociology of the body, emotion and health. Arguments for a ‘biological’, and yet social, body are considered before developing a critique of work on the sociology of the biological body. It is argued that there are a number of difficulties with this latter project. Writers working in this area can be seen to have used rather emotional ploys to advance their promotion of a more ‘biologised’, or ‘material‐corporeal’, account of the body, emotion and health. In addition though these writers eschew reductionist, naturalist, and dualist arguments, they nevertheless draw on studies that have some or all of these characteristics. Finally a variety of epistemological and methodological difficulties inherent in physiological analysis and in ‘interviewing’ the body are explored. It is concluded that we still remain near the ‘starting point’ of a sociology of the body that interrelates biology and sociology.     

Material civilization: things and society

This paper argues that although classical sociology has largely overlooked the importance of social relations with the material world in shaping the form of society, Braudel's concept of 'material civilization' is a useful way to begin to understand the sociological significance of this relationship. The limitations of Braudel's historical and general concept can be partially overcome with Elias's analysis of the connection between 'technization' and 'civilization' that allows for both a civilizing and a de-civilizing impact of emergent forms of material relation that both lengthen and shorten the chains of interdependence between the members of a society. It is suggested that the concept of the 'morality of things' employed by a number of commentators is useful in summarizing the civilizing effects of material objects and addressing their sociological significance. From the sociology of consumption the idea of materiality as a sign of social relationships can be drawn, and from the sociology of technology the idea of socio-technical systems and actor-networks can contribute to the understanding of material civilization. It is argued that the concept of 'material capital' can usefully summarize the variable social value of objects but to understand the complexity of material civilization as it unfolds in everyday life, an analysis of 'material interaction' is needed. Finally the paper suggests some initial themes and issues apparent in contemporary society that the sociological study of material civilization might address; the increased volume, functional complexity and material specificity of objects and the increased social complexity, autonomy and substitutability that is entailed. A theory of 'material civilization' is the first step in establishing a sociology of objects.
