Evaluating the Efficacy of a Mental Models Approach for Improving Occupational Chemical Risk Protection

Chemical risk protection in the workplace relies partly on informing workers about possible risks using material safety data sheets (MSDS). This article reports on phase 2 of a project (phase 1 reported in Cox et al.), which employed a mental models approach to improve on data sheets as communicative interventions for perchloroethylene in dry cleaning and rosin-based solder flux in the electronics industry within small businesses in the United Kingdom (small enterprises (SEs) < 25 employees in the workplace). It focuses on the efficacy of a multimethod evaluation strategy to assess (1) the capacity of a mental models approach to yield contextually relevant data for intervention design and (2) the effectiveness of the strategy itself in validating the mental models data. The evaluation was conducted using postal questionnaires and semi-structured verbal protocols to provide responses to the alternative intervention content and to prioritize risk messages. User discussion groups were then employed, particularly as a means of establishing whether contextual information could be obtained that would differ qualitatively from the kind elicited through individual (semi) structured methods. We conclude that the mental models approach as part of an iterative process including systematic multimethod evaluation is successful in supporting the design of relevant communications to the users of chemicals. The overall viability of communicative interventions in the context of health and safety in small businesses remains in question. Future research might aim to develop a more holistic approach to interventions in complex occupational contexts.     

The Impact of Occupational Sex Segregation on Family Businesses: The Case of American Harness Racing

Previous research on occupational sex segregation agrees that the workplace is not an isolated world but instead influences, and is influenced by, other spheres of social life. Identifying specific social factors both internal and external to the workplace, and how these may interact, can provide deeper insights into how occupational sex segregation is created and maintained. This study focuses on individual family businesses in American harness horse racing, a previously unexamined and highly sex‐segregated industry, and provides insights in how vertical and horizontal sex segregation may develop in family businesses. The findings show how the belief that married couples cannot debate and resolve work‐related conflicts without undue strain on their personal relationship leads some of these couples to organize their work into gendered tasks and workspaces, contributing to the maintenance of vertical segregation in the trainer position. The implications for segregation of other solutions, such as operating separate businesses, or working for another business, are less clear.     

Women's Work,Dirty Work: The Gynaecology Nurse as ‘Other’

This article seeks to explore the world of the gynaecology nurse. This world defines the gendered experience of nursing; that is, women in a women's job carrying out ‘women's work’. It is also a world that receives scant public recognition due to its association with the private domain of women's reproductive health. Many issues dealt with on a daily basis by gynaecology nurses are socially ‘difficult’: cancer, infertility, miscarriage and foetal abnormalities; or socially ‘distasteful’: termination of pregnancy, urinary incontinence, menstruation and sexually transmitted disease. The ‘tainted’ nature of gynaecology nursing gives it the social distinction of ‘dirty work’ but does not deter the gynaecology nurse from declaring her work as ‘special’, requiring distinctive knowledge and skills. Qualitative data collected from a group of gynaecology nurses in a North West National Health Service hospital displays how they actively celebrate their status as women carrying out ‘dirty work’. Through the use of ceremonial work that continually re‐affirms their ‘womanly’ qualities the gynaecology nurses establish themselves as ‘different’, as ‘special’, as the ‘other’.

Musculoskeletal discomfort and work-related stress in New Zealand dentists

There has been little research into the stressors, psychological distress and musculoskeletal symptoms experienced by dentists. The present study was carried out among a random sample of New Zealand dentists (N=413). The present study aimed to identify the severity of work psychosocial stressors, examine the occurrence of musculoskeletal discomfort and psychological disturbance, and determine relationships between these factors. The average age of the dentists was 43 years, with 74% being male. The annual prevalence of symptoms in both the lower back or neck was 63%, with 49% experiencing symptoms in the shoulders. Older dentists were no more likely to suffer musculoskeletal discomfort than younger dentists. The highest ranking dentistry-specific work-related stressor was 'patients having a medical emergency' with 78% scoring this stressor very highly. Dentists scored mental demands as the highest general work-related stressor. One-fifth of the dentists scored highly for psychological disturbance, which was very similar to the general population. Dentists with high scores for dentistry-specific work-related stressors were more likely to have evidence of psychological disturbance. The relationships between psychological disturbance and musculoskeletal discomfort needs to be taken into account when considering any multidisciplinary approach to prevention.     

Public Distrust and Hazard Management Success at the Rocky Flats Nuclear Weapons Plant

Based on experience gained while serving a public oversight commission appointed by the governor of Colorado, hazard management at the Department of Energy's Rocky Flats nuclear weapons plant is reviewed. Specific reference is made to the plant's history of controversy, its defense-in-depth strategy of hazard control, occupational health issues, public exposure to plutonium, and the assessment of low-probability, high-consequence risks. This leads to the conclusion that Rocky Flats is, by any objective standard, a hazard management success. It follows that public distrust of Rocky Flats arises as much from fear and loathing of nuclear weapons themselves as from the manufacturing process by which they are made.     

A Quantitative Estimate of Leukemia Mortality Associated with Occupational Exposure to Benzene3

In 1980, the U.S. Supreme Court vacated a revised occupational standard for benzene, stating that the Occupational Safety and Health Administration (OSHA) had failed to demonstrate that significant health risks existed under the current standard. This decision has been interpreted by OSHA as requiring the consideration of quantitative risk assessments, whenever possible, in the development of regulations for occupational carcinogens. In light of this decision, the available epidemiologic evidence was used to generate a quantitative risk assessment for benzene. Uncertainties regarding the levels and lengths of benzene exposure for the studied cohorts were incorporated into the analysis. Based on the one-hit model, the assessment indicates that a working lifetime exposure to benzene at the current permissible exposure level (10 ppm) poses a substantial excess risk of death from leukemia. This report discusses the calculation of the risk estimates, the basis for relying on certain assumptions, and the inherent limitations of using epidemiologic studies to quantify cancer risks.     

The Effects of Divorce on Men’s Employment and Social Security Histories

Analyses of the economic consequences of divorce have emphasized the negative effect of divorce for women. For men, consequences of divorce are most often believed to be social or psychological. This is not consistent with an economic literature showing the positive effects of marriage on men’s wages. Using a nationally representative life-history survey among men in the Netherlands, this paper reanalyzes the possible negative effects of a divorce for the careers of men. Complete life histories provide information on upward and downward occupational mobility as well as on unemployment and disability. Multivariate event history models show that after divorce, men experience an increased chance of becoming downwardly mobile, an increased chance of becoming unemployed, and an increased chance of becoming disabled. Additional analyses are done to assess whether these effects are spurious, due to the influence of earlier problems that men experienced in their lives, as measured by indicators of employment problems, health problems, and problems in social relationships. While these variables have an effect on the future career, they are not strong enough to eliminate the divorce effect. Implications are discussed for different theoretical hypotheses about the importance of marriage and divorce for men’s employment.
