Centring labour in financialization

ABSTRACT

This article draws on an engagement with Marx’s notes on money and finance to reconsider the relationships between labour, working classes, and financial accumulation. In recent years, these dynamics have often been understood through the lens of ‘financialization’ – referring to a trend towards the growing prominence of financial sector profits, logics, and power at the expense of productive activity. This lens has tended to produce analyses of labour and finance that are (1) unidirectional and (2) that often lump a wide range of developments under a single heading without considering how these trends might intersect in potentially contradictory ways. Marx offers a useful alternative insofar as his approach to money and finance centres on a continual and fraught dynamic between the ‘abstract’ social labour embodied in money and the ‘concrete’ labour performed in particular places at particular times. This argument is illustrated through brief vignettes from South Africa.     

The Perceived Health Risks of Indoor Radon Gas and Overhead Powerlines: A Comparative Multilevel Approach

Radon and overhead powerlines are two radiation risk cases that have raised varying levels of concern among the general public and experts. Despite both involving radiation—a typically feared and unseen health hazard—individuals' perceptions of the two risk cases may invoke rather different factors. We examined individual and geographic-contextual factors influencing public perceptions of the health risks of indoor radon gas and overhead powerlines in a comparative research design, utilizing a postal questionnaire with 1,528 members of the general public (response rate 28%) and multilevel modeling techniques. This study found that beliefs about the two risk cases mainly differed according to the level of "exposure"—defined here in terms of spatial proximity. We argue that there are two alternative explanations for this pattern of findings: that risk perception itself varies directly with proximity, or that risk is more salient to concerned people in the exposed areas. We also found that while people living in high radon areas are more concerned about the risks of indoor radon gas, they find these risks more acceptable and have more trust in authorities. These results might reflect the positive effects of successive radon campaigns in high radon areas, which may have raised awareness and concern, and at the same time may have helped to increase trust by showing that the government takes the health risks of indoor radon gas seriously, suggesting that genuine risk communication initiatives may have positive impacts on trust in risk management institutions.

Exercising moral agency in the contexts of objective reality: toward an integrated account of ethical consumption

This paper engages with two contrasting approaches to conceptualising and studying consumer behaviour that appear to dominate existing research on consumption. On one hand, agency‐focused perspectives take an individual consumer to be the primary author of practice and a basic unit of analysis. On the other hand, socio‐centric paradigms focus on the social roots of consumption activities and the wider societal contexts in which they take place. The need to provide a more balanced view of consumption phenomena has been acknowledged, yet not adequately acted upon. This paper begins to fill this gap through relevant theoretical and empirical contributions. First, we provide a critical review of the dominant theoretical perspectives on consumption in general and ethical consumption in particular, highlight their key ontological assumptions and explain how they preclude a fuller understanding of the ways in which consumer practices are moulded and shaped. Taking a critical realist approach, we then present the findings from qualitative analysis of consumers' ethical food practices to empirically demonstrate the role of human agency and social structure in creating and shaping ethical consumption. Thus, by means of theoretical analysis and empirical research this paper responds to the call for a more comprehensive understanding of consumption and provides a consolidated account of consumer behaviour which acknowledges and explains the complex ensemble of individual and systemic powers in which consumer practices are contained.     

The permutation flow shop problem with just in time production considerations

This research presents a variation to the permutation flow shop problem where Just In Time (JIT) production requirements are taken into account. The model developed in this research employs dual objectives. In addition to the traditional objective of minimizing the production makespan, minimization of Miltenburg's material usage rate is also incorporated. In this model, multiple units of any product are permitted in the production sequence. However, the minimization of material usage rates attempts to prevent batch scheduling of products and allows unit flow of products as required in demand flow manufacturing. A solution method is proposed for determining an optimal production sequence via an efficient frontier approach and Simulated Annealing (SA). Test problems and specific performance criteria are used to assess the solutions generated by the proposed method. Experimental results presented in this paper show that the use of the efficient frontier and SA provide solutions that approach the optimal solution for the performance measures used in this research.
