This article presents a sociological study of sleep issues in the British print news media, with particular focus on the relationship between sleep, work and the changing demands of ‘flexible capitalism’. Drawing on over 1000 newspaper articles from 1984 to 2005, we explore how and why sleep is framed or constructed in terms of continuity and change (in British working life and work cultures) and, equally, viewed as a neglected component of our social lives which is too easily sacrificed to the demands of the 24/7 society, long hours culture and the struggle to create a harmonious work-life balance. This is particularly the case for certain British work cultures in which sleep has conflicting and contrasting associations. Finally, we reflect on the broader class-based discourses and debates that arise from certain workers having their sleep patterns increasingly scrutinized and regulated, and the role of the media in any ensuing sleep/work ‘crisis’.

Data obtained from full-time employees of a public sector organization in India were used to test a social exchange model of employee work attitudes and behaviors. LISREL results revealed that whereas the three organizational justice dimensions (distributive, procedural and interactional) were related to trust in organization only interactional justice was related to trust in supervisor. The results further revealed that relative to the hypothesized fully mediated model a partially mediated model better fitted the data. Trust in organization partially mediated the relationship between distributive and procedural justice and the work attitudes of job satisfaction, turnover intentions, and organizational commitment but fully mediated the relationship between interactional justice and these work attitudes. In contrast, trust in supervisor fully mediated the relationship between interactional justice and the work behaviors of task performance and the individually- and organizationally-oriented dimensions of citizenship behavior.

This investigation explores the effects of organizational identification on employees’ Implicit Leadership Theories (ILTs) and the perception of leader behaviors. The study involved a cross-sectional survey of 439 employees from seven companies based in South Wales. Respondents completed two questionnaires that measured their organizational identification, ILTs, recognition of ILTs in their manager, manager’s leadership behaviors (transactional and transformational), and psychological reactions (job satisfaction, well-being, and turnover intentions). The level of organizational identification did not affect the prototype of an ideal work-based leader. However, high organizational identification was associated with more positive ratings on the actual manager, the extent to which their manager displayed transactional and transformational behaviors, and with more positive psychological reactions to work. Employees high in organizational identification based their judgments of their leader’s transactional and transformational behaviors on the extent to which they recognized their leader as possessing leadership traits. However, those low on organizational identification allowed their prototype of their ideal leader to bias their judgment of their actual leader’s behavior. Finally, there was partial support for the augmenting hypothesis (that tranformational leadership would predict additional variance in psychological outcomes above that predicted by transactional leadership) for those high in organizational identification but not for those low in organizational identification.

The relationship between locus of control, the quality of exchanges between subordinates and leaders (LMX), and a variety of work-related reactions (intrinsic/extrinsic job satisfaction, work-related well-being, and organizational commitment) are examined. It was predicted that people with an internal locus of control develop better quality relations with their manager and this, in turn, results in more favourable work-related reactions. Results from two different samples (N=404, and N=51) supported this prediction, and also showed that LMX either fully, or partially, mediated the relationship between locus of control and all the work-related reactions.

This thesis is an exploration of the social and political processes involved in the introduction of new technology to the shopfloor. Through a series of case studies of applications of microelectronics to batch manufacture, it attempts to uncover the ways in which the values and interests of managers, engineers, workers and others profoundly influence the choice and use of technology, and thus the work organisation which emerges. Previous analyses have tended to treat new technology as if it had "impacts" on work organisation - especially skills - which are inevitable in particular technical and economic circumstances. It is in opposition to this view that technical change is here treated as a matter for social choice and political negotiation, the various interested parties to the change being shown to attempt to incorporate their own interests into the technical and social organisation of work. Section one provides the relevant background to the case studies by summarising and criticising previous theoretical and empirical work in the area. The inadequacies of this work for our concerns are drawn out, and the need for detailed studies of the political aspects of technical change is justified. The case studies are presented in section two as a set of "episodes" of innovation, and section three analyses the empirical findings. The innovations are compared and contrasted in order to illustrate the social and political dynamics involved in the various stages of the innovation process. Finally some comments are made on policy issues for which the research has important implications.

Background: During ageing an altered redox balance has been observed in both intracellular and extracellular compartments, primarily due to glutathione depletion and metabolic stress. Maintaining redox homeostasis is important for controlling proliferation and apoptosis in response to specific stimuli for a variety of cells. For T cells, the ability to generate specific response to antigen is dependent on the oxidation state of cell surface and cytoplasmic protein-thiols. Intracellular thiols are maintained in their reduced state by a network of redox regulating peptides, proteins and enzymes such as glutathione, thioredoxins and thioredoxin reductase. Here we have investigated whether any relationship exists between age and secreted or cell surface thioredoxin-1, intracellular glutathione concentration and T cell surface thioredoxin 1 (Trx-1) and how this is related to interleukin (IL)-2 production.Results: Healthy older adults have reduced lymphocyte surface expression and lower circulating plasma Trx-1 concentrations. Using buthionine sulfoximine to deplete intracellular glutathione in Jurkat T cells we show that cell surface Trx-1 is lowered, secretion of Trx-1 is decreased and the response to the lectin phytohaemagglutinin measured as IL-2 production is also affected. These effects are recapitulated by another glutathione depleting agent, diethylmaleate.Conclusion: Together these data suggest that a relationship exists between the intracellular redox compartment and Trx-1 proteins. Loss of lymphocyte surface Trx-1 may be a useful biomarker of healthy ageing. © 2013 Carilho Torrao et al.; licensee Chemistry Central Ltd.

An applied psychological framework for coping with performance uncertainty in sport and work systems is presented. The theme of personal control serves to integrate ideas prevalent in industrial and organisational psychology, the stress literature and labour process theory. These commonly focus on the promotion of tacit knowledge and learned resourcefulness in individual performers. Finally, data from an empirical evaluation of a development training programme to facilitate self-regulation skills in professional athletes are briefly highlighted.

This paper introduces a theoretical framework to guide research into the psychological effects of advanced manufacturing technology (AMT) on shopfloor operators. The framework has two main aspects. First, based on the emerging literature on the job content implications of AMT, it identifies four key constructs, namely: control, cognitive demand, production responsibility and social interaction. Second, by drawing on the more established job design, stress and related literatures, it predicts how these independent variables differentially affect system performance, job-related strain and job satisfaction. The wider implications and limitations of the theoretical framework are discussed.
