UK construction safety: a zero paradox?

The zero accident mantra has become embedded within the safety discourse of large UK construction organisations, but the extent to which zero-focused approaches yield reductions in accident frequency is yet to be empirically investigated. By way of an evidence-based critique, we examine the relationship between major accidents and zero approaches by drawing on Health and Safety Executive accident data over a 4 year period, together with an analysis of major contractors’ safety approaches. This reveals that working on a project subject to a zero safety policy or programme actually appears to slightly increase the likelihood of having a serious life-changing accident or fatality; a possible ‘zero paradox’. Although these findings should be treated with caution, they suggest that the apparent trend towards abandoning zero amongst some large organisations is well-founded. As such, if zero policies stymie learning whilst failing to reduce accidents, the need for a countervailing discourse is clear

Affective atmospheres of sensemaking and learning:Workplace meetings as aesthetic and anaesthetic

The aim of this article is to explore sensemaking and learning processes with and through affective atmospheres. We engage with recent research within the ‘affective turn’ across the social sciences and humanities to conceptualize the significance of quasi-autonomous affective atmospheres that emanate from, and also condition, collectives of humans and non-humans. Drawing on this atmospheric scholarship, we propose and elaborate an atmospheric analysis of sensemaking and learning processes to examine how such atmospheres aesthetically transform, and anaesthetically constrain, the potential of bodies, including our own as researchers, to affect and be affected to sense and learn. Through empirical engagement with workplace meetings in a UK housebuilding firm, our analysis contributes by explaining how such atmospheres condition sensemaking that both registers the disorganizing novelty of events and reduces such ambiguity and equivocality to enable purposeful action. While extant research has suggested how the interplay of these two dimensions of sensemaking enables learning, our analysis contributes by drawing attention to how the production, maintenance and transformation of specific atmospheres in workplace meetings imbues affects that condition these two dimensions of sensemaking. Such atmospheres thus constitute vital, yet seldom discussed, phenomena in conditioning learning within organizational life

Exploring the organizational proliferation of new technologies:an affective actor-network theory

In this paper we explore the role of affective encounters between human and non-human bodies in the proliferation of new technologies within and across work organizations. Our exploration challenges not only the long-standing rationalism within studies of technological innovation but the anthropocentrism of burgeoning studies of technology, innovation and affect. Responding to these proclivities, we propose and elaborate an affective Actor-Network Theory (ANT) as an alternative analytical approach by cross-fertilizing ANT concepts with Deleuze’s reading of the affective philosophy of Spinoza. Our approach is elaborated further with the technological innovation of zero-carbon homes in the United Kingdom. Affective ANT is proposed to explain the profound role of affects in the circulation of technologies and of technologies in the circulation of affects. This theory contributes by challenging: studies of affect, innovation and technology to examine the significance of relational human affects in the proliferation of new technologies; organizational studies to consider the interplay of human and technical affects; and Deleuzo-Spinozian organizational studies to conceptualize how affects are organized to serve managerial interests and agendas, such as technological innovation

Principles for the design and operation of engineer-to-order supply chains in the construction sector

By integrating the approaches of Forrester and Burbidge [Forrester, J. W. 1961. Industrial Dynamics. Pegasus Communications; Burbidge, J. L. 1961. “The “New Approach” to Production.” Production Engineer 40: 769–784], a set of five design principles have emerged which provide a foundation for sound supply chain design. The ‘FORRIDGE’ principles have since been shown to be a powerful guide for effective design of make-to-stock supply chains. However, some have questioned the applicability of generic supply chain thinking, arguing for a tailored approach. Hence, the goal here is to investigate how these principles should be adapted for engineer-to-order (ETO) industries, such as construction, capital goods and shipbuilding. The empirical elements draw on an extensive study of 12 suppliers and two large contractors in the construction industry. Supply chain tactics are identified for this range of companies, which are matched with real world problems, and linked with the FORRIDGE principles. This results in an additional ‘Design for X’ principle being proposed. The contributions made are the adaptation of established principles for the ETO sector, and the framework behind these principles

Balancing employee needs, project requirements and organisational priorities in team deployment

The 'people and performance' model asserts that performance is a sum of employee ability, motivation and opportunity (AMO). Despite extensive evidence of this people-performance link within manufacturing and many service sectors, studies within the construction industry are limited. Thus, a recent research project set out to explore the team deployment strategies of a large construction company with the view of establishing how a balance could be achieved between organisational strategic priorities, operational project requirements and individual employee needs and preferences. The findings suggested that project priorities often took precedence over the delivery of the strategic intentions of the organisation in meeting employees' individual needs. This approach is not sustainable in the long term because of the negative implications that such a policy had in relation to employee stress and staff turnover. It is suggested that a resourcing structure that takes into account the multiple facets of AMO may provide a more effective approach for balancing organisational strategic priorities, operational project requirements and individual employee needs and preferences more appropriately in the future

Adolescent time use and mental health: a cross-sectional, compositional analysis in the Millennium Cohort Study

OBJECTIVE: To examine the association of 24-hour time-use compositions with mental health in a large, geographically diverse sample of UK adolescents. DESIGN: Cross-sectional, secondary data analysis. SETTING: Millennium Cohort Study (sixth survey), a UK-based prospective birth cohort. PARTICIPANTS: Data were available from 4642 adolescents aged 14 years. Analytical samples for weekday and weekend analyses were n=3485 and n=3468, respectively (45% boys, 85% white ethnicity). PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcome measures were the Strengths and Difficulties Questionnaire (SDQ, socioemotional behaviour), Mood and Feelings Questionnaire (MFQ, depressive symptoms) and Rosenberg Self-Esteem Scale (RSE, self-esteem). Behavioural exposure data were derived from 24-hour time-use diaries. RESULTS: On weekdays, participants spent approximately 54% of their time in sleep, 3% in physical activity, 9% in school-related activities, 6% in hobbies, 11% using electronic media and 16% in domestic activities. Predicted differences in SDQ, MFQ and RSE were statistically significant for all models (weekday and weekend) that simulated the addition or removal of 15 min physical activity, with an increase in activity being associated with improved mental health and vice versa. Predicted differences in RSE were also significant for simulated changes in electronic media use; an increase in electronic media use was associated with reduced self-esteem. CONCLUSION: Small but consistent associations were observed between physical activity, electronic media use and selected markers of mental health. Findings support the delivery of physical activity interventions to promote mental health during adolescence, without the need to specifically target or protect time spent in other activities

Understanding employee resourcing in construction organizations

In recent years the literature on employee resourcing has consistently advocated the importance of adopting a holistic, strategic approach to employee deployment decision making rather than adopting a reactive needs-based approach. This is particularly problematic in construction where the multi-project environment leads to constantly changing resource requirements and to changing demands over a project's life cycle. This can lead to inappropriate decisions, which fail to meet the longer-term needs of both construction organizations and their employees. A structured and comprehensive understanding of the current project team deployment practices within large construction organizations was developed. Project deployment practices were examined within seven case study contracting firms. The emergent themes that shaped the decision-making processes were grouped into five broad clusters comprising human resource planning, performance/career management, team deployment, employee involvement and training and development. The research confirms that a reactive and ad hoc approach to the function prevails within the firms investigated. This suggests a weak relationship between the deployment process and human resource planning, team deployment, performance management, employee involvement and training and development activities. It is suggested that strategic HR-business partnering could engender more transparent and productive relationships in this crucial area

Selenium supplementation has beneficial and detrimental effects on immunity to influenza vaccine in older adults

Background & aims: Mortality resulting from influenza (flu) virus infections occurs primarily in the elderly through declining immunity. Studies in mice have suggested beneficial effects of selenium (Se) supplementation on immunity to flu but similar evidence is lacking in humans. A dietary intervention study was therefore designed to test the effects of Se-supplementation on a variety of parameters of anti-flu immunity in healthy subjects aged 50–64 years. Methods: A 12-week randomized, double-blinded, placebo-controlled clinical trial (ClinicalTrials.gov NCT00279812) was undertaken in six groups of individuals with plasma Se levels <110 ng/mL. Four groups were given daily capsules of yeast enriched with 0 μg Se/day (SeY-0/d; n = 20), 50 μg Se/d (SeY-50/d; n = 18), 100 μg Se/d (SeY-100/d; n = 21) or 200 μg Se/d (SeY-200/d; n = 23). Two groups were given onion-containing meals with either <1 μg Se/d (SeO-0/d; n = 17) or 50 μg Se/d (SeO-50/d; n = 18). Flu vaccine was administrated at week 10 and immune parameters were assessed until week 12. Results: Primary study endpoints were changes in cellular and humoral immune responses. Supplementation with SeY and SeO affected different aspects of cellular immunity. SeY increased Tctx-ADCC cell counts in blood (214%, SeY-100/d) before flu vaccination and a dose-dependent increase in T cell proliferation (500%, SeY-50/100/200/d), IL-8 (169%, SeY-100/d) and IL-10 (317%, SeY-200/d) secretion after in vivo flu challenge. Positive effects were contrasted by lower granzyme B content of CD8 cells (55%, SeY-200/d). SeO (Se 50 μg/d) also enhanced T cell proliferation after vaccination (650%), IFN-γ (289%), and IL-8 secretion (139%), granzyme (209%) and perforin (190%) content of CD8 cells but inhibited TNF-α synthesis (42%). Onion on its own reduced the number of NKT cells in blood (38%). These effects were determined by comparison to group-specific baseline yeast or onion control groups. Mucosal flu-specific antibody responses were unaffected by Se-supplementation. Conclusion: Se-supplementation in healthy human adults with marginal Se status resulted in both beneficial and detrimental effects on cellular immunity to flu that was affected by the form of Se, supplemental dose and delivery matrix. These observations call for a thorough evaluation of the risks and benefits associated with Se-supplementation
