Birth preference in women undergoing treatment for childbirth fear: A randomised controlled trial

Background

Childbirth fear is the most common underlying reason for requesting a caesarean section without medical reason. The aim of this randomised controlled study was to investigate birth preferences in women undergoing treatment for childbirth fear, and to investigate birth experience and satisfaction with the allocated treatment.

On Locating and Characterizing Parameter Variation by the Mosumsq Test Statistic

In modelling a system structure it is often important to test the constancy of the structural parameters. If the hypothesis of constant parameters is rejected we wish to characterize the parameter variation. In this paper we examine the usefulness of the MOSUMSQ test statistics for locating and characterizing the parameter variation in linear regression models. The means and the variances of the test statistics are given for non-random parameter variation. The observed path of the MOSUMSQ test statistics provides valuable knowledge about the time of the onset of the parameter change and whether it is instantaneous or gradual.     

Dual-earner migration. Earnings gains, employment and self-selection

This paper examines how spouses in dual-earner couples weigh each partner’s expected wage growth in the decision to migrate. Previous research suggests that husbands’ job prospects dominate the migration choice irrespective of their relative earnings potential. Based on British panel data, this paper employs an endogenous switching model and estimates wage differentials of migrating vs. staying for husbands and wives corrected for double selectivity of migration and employment. Dual-earner couples attach a positive weight to each partner’s expected wage gains when deciding to migrate. Moreover, migrant wives’ employment decreases temporarily, and there are significant selection effects in migration and employment amongst non-migrants.     

Gender‐specific Effects at Work: An Empirical Study of Four Countries

Using a questionnaire based upon the work of Geert Hofstede, we examined the effects of gender on the following three work‐related dimensions: the importance of work‐related goals, the preference for performance rewards and the preference for management styles. The study was conducted for a multinational corporation headquartered in Germany with branches in China, Japan and the USA. Even though some inter‐country differences in the importance of work‐related matters are identified and intra‐country gender differences exist in work goal evaluation, overall we find that men and women exhibit similar preferences concerning performance rewards and managerial styles. Finally, for the three dimensions studied, our data do not confirm the stereotypical work‐related gender differences often reported in the literature and popular press.     

Participative development of packages in the food industry--evaluation of ergonomics and productivity by objective measurements

Rationalizations generally have a negative effect on health and known risk factors for musculoskeletal disorders. These effects may be reduced by paying attention to modifiers as worker participation and a resonant management style. In this study a participatory approach was used in the food industry in order to improve ergonomics and productivity. The food industry shows a high prevalence of musculoskeletal disorders, and repetitive manual work occurs extensively. Prototypes of new packaging solutions were developed in three cases, and compared in a simulated production to the existing production system through direct measurements of working postures and muscle activity, ratings of physical load, and general productivity data. Measured and rated ergonomic exposures showed that workload was significantly lower for the prototypes, in all three cases. In two cases, the number of handling operations included in the packaging operations were greatly reduced with the prototype package, as were production costs. The impact on disorders of the obtained load reductions is difficult to assess, but we believe that in "critical" situations like this, even small improvements may have an effect. This study shows that workloads during manual handling of packages as well as production costs can be reduced by applying participative development of packages.     

Workload and morning salivary cortisol in women

Previous studies have shown a link between work-related stress and the morning level of the stress hormone cortisol. The level of cortisol in the circulation is regulated by the hypothalamic-pituitary-adrenocortical (HPA) axis, dysregulation of which plays an important role in a number of disorders including hypertension, immune deficiency and being overweight (the 'metabolic syndrome'). The aim of this study was to investigate the association between workload and morning cortisol in women. Saliva samples were obtained four times during the first 45 min after awakening (0, 15, 30 and 45 min) in the morning on a work-free day from more than 200 women in full-time work who were born in 1955 and representing a normal population of a small city in Sweden. The amount of paid and unpaid work was reported in a questionnaire. Significant positive correlations were found between the amount of overtime at work and each of the four measurements of morning salivary cortisol (varying from r = .29 to r = .38, p < .01). In addition, participants with excessive overtime (more than 10 h/week) had on average about twice as high ( p < .01) morning cortisol levels as women with moderate overtime (< 10 h/week) or normal working hours (35-40 h/week). The results are consistent with earlier findings and suggest that morning cortisol is a sensitive indicator of work overload in women. However, additional research is necessary in order to reveal the specific pathways linking work-related stress to elevated morning cortisol.
