Trust, inequality and the market

This article examines, experimentally, whether inequality affects the social capital of trust in non-market and market settings. We consider three experimental treatments, one with equality, one with inequality but no knowledge of the income of other agents, and one with inequality and knowledge. Inequality, particularly when it is known, has a corrosive effect on trusting behaviours in this experiment. Agents appear to be less sensitive to known relative income differentials in markets than they are in the non-market settings, but trust in markets appears generally more vulnerable to the introduction of inequality than in the non-market setting.     

The functional capacity of healthcare workers with history of severe acute respiratory distress syndrome (SARS) complicated with avascular necrosis--case report

Two years after the SARS outbreak in Hong Kong, 128 healthcare workers continued to present with musculoskeletal complaints and 38 workers were diagnosed with avascular necrosis (AVN) in different joints. 13 healthcare workers were referred to six designated Physiotherapy Departments of the Hospital Authority for a tailor-made standardized Functional Capacity Evaluation (FCE) from 2004 to 2005 on a voluntary basis. Job analysis, workers' self-perceived disability and functional capacity, non-material handling tests, and the cardiopulmonary fitness test were performed. Retrospective review of the FCE data showed that there were 17 AVN of hips, 16 AVN of knees, 3 AVN of shoulders. All patients had AVN of lower limb joints. Nearly full ranges of movement (ROM) were observed in the knees involved, but the hip range was decreased for most subjects suffering from hip AVNs. Most workers (n=12) could not complete the cardiopulmonary test due to intolerable joint pain. Six workers' self-perceived physical demands level (PDC) matched with the physical demands level identified by the FCE. 12 healthcare workers attained a sedentary physical demands level and were unable to match with their previous job demands. One staff was classified as light physical demands and managed his original duty. Four workers had returned to work at the time FCE was performed. The tailor-made FCE added information to facilitate the return-to-work planning for the staff. Four more workers returned to work with modified duties one year after the FCE.     

Staging language: An introduction to the sociolinguistics of performance

Staged performance involves the overt, scheduled identification and elevation of one or more people to perform, with a clearly demarcated distinction between them and the audience. It involves the agentive use of language, building on the foundation of existing social meanings. Staged performances tend to be linguistically stylized, pushing the limits of language creativity. They have the potential to trigger significant sociolinguistic effects, circulating novel forms and contributing to language change. The paradigms used in this theme issue for approaching language performance include Bakhtin's notion of Stylization, Bell's Audience and Referee Design, Silverstein's Indexicality, Agha's Enregisterment, and Bauman's construct of Discursive Culture. Themes that run through the articles include: a concept of identity that is part product, part process; the centrality of the audience; the reflexivity of staged performance; and the importance of non‐linguistic modalities such as music and appearance. The language analysis in this collection of papers concentrates mainly on phonological features of varieties of English, finding instances of selectivity, mis‐realization, overshoot and undershoot in their performances of a range of targeted dialects.     

Preference Change and Increasing Wage Inequality

Abstract. This paper argues that preference change could explain, in part, the growth of within‐group wage inequality in the USA and the UK in the 1980s. The absence of such preference change in continental European countries might also help explain why their wage inequality did not rise in the same way. The argument relies on evidence from the World Values Surveys and uses an efficiency wage model of within‐group wage inequality where there are differences in the degree of discretion at work across firms and workers value not just the wage but also the degree of discretion on the job.     

Commitment to the union: a survey of research and the implications for industrial relations and trade unions

This paper presents an overview of the literature on union commitment. The aim is to survey the main approaches, findings and implications of the research. The nature and dimensionality of union commitment are examined, and the antecedents and consequences of union commitment are discussed in detail, including a review of the implications for union participation. There is also a discussion of the possibility of dual commitment to union and employer, and of the 'multiple constituencies' view of commitment. An attempt is made to link the union commitment findings to the wider industrial relations literature on, for example, why people join unions and the 'union renewal' thesis. The article concludes by discussing the implications of the literature for union–management relationships and for unions themselves, and with some suggestions for future research.     

Student Perceptions of Web-Assisted Teaching Strategies

This study determines which Web-assisted teaching strategies social work students from a single university experience and perceive as valuable. The results demonstrate that most faculty use email, post grades online, and give out student email addresses to the class. Students perceive email communication with the instructor and the online provision of course information as the most valuable strategies. The impact of several student characteristics on value perception is also examined, revealing varying levels of influence. These findings suggest that the strategies students report as the most valuable are not necessarily the strategies most frequently used by faculty.     

Conditional Gaussian mixture modelling for dietary pattern analysis

Summary.  Free-living individuals have multifaceted diets and consume foods in numerous combinations. In epidemiological studies it is desirable to characterize individual diets not only in terms of the quantity of individual dietary components but also in terms of dietary patterns. We describe the conditional Gaussian mixture model for dietary pattern analysis and show how it can be adapted to take account of important characteristics of self-reported dietary data. We illustrate this approach with an analysis of the 2000–2001 National Diet and Nutrition Survey of adults. The results strongly favoured a mixture model solution allowing clusters to vary in shape and size, over the standard approach that has been used previously to find dietary patterns.
