Predictors of disability retirement: From early intentions to retirement

The strong tendency of elderly employees to retire early and the simultaneous aging of the population have been major topics of policy and scientific debate. A key concern has been the financing of future pension schemes and possible labour shortage, especially in social and health services within the public sector. The aging of the population is inevitable, but efforts can be made to prevent or postpone early exit from the labour force, e.g., by identifying and intervening in the factors that contribute to the process of early retirement due to disability. The associations of intentions to retire early, poor mental health and different psychosocial factors with the process of disability retirement are still poorly understood. The purpose of this study was to investigate the associations of intentions to retire early, poor mental health, work and family related psychosocial factors and experiences of earlier life stages with the process of disability retirement. The data were derived from the Helsinki Health Study (HHS, N=8960) and the Health and Social Support Study (HeSSup, N=25 901). The Helsinki Health Study is an ongoing employee cohort study among middle-aged women and men. The Health and Social Support Study is an ongoing longitudinal study of a working-age sample representative of the Finnish population. The analyses were restricted to respondents 40 years of age or older. Age and gender adjusted prevalence and incidence rates were calculated. Associations were studied by using logistic, multinomial and Cox regression. Strong intentions to retire early were common among employees. Poor mental health, unfavourable working conditions and work-to-family conflicts were clearly associated with increased intentions to retire early. Strong intentions to retire early predicted disability retirement. Risk of disability retirement increased in a dose-response manner with increasing number of childhood adversities. Poor mental and somatic health, life dissatisfaction, heavy alcohol consumption, current smoking, obesity and low socioeconomic status were also predictors of disability retirement. The impact of poor mental health and adverse experiences from earlier life stages, work and family related psychosocial factors, e.g., work-family interface, the subjective experience of well-being and health related risk behaviours on the process of disability retirement should be recognised. Preventive measures against disability retirement should be launched before subjective experience of ill health, work disability and strong intentions to retire early emerge.

Finnish Business Repatriates' Coping Strategies

This thesis explores Finnish business repatriates’ coping strategies. Managing repatriation has been recognized as a demanding task for companies and an important issue in international human resource management. However, we still know relatively little about how repatriates respond to the demands of the return. This thesis addresses this problem by applying a process approach to coping with repatriation. The focus is on identifying repatriates’ coping strategies and the various forms of them. This study also aims to investigate what might influence the use of repatriates’ coping strategies and forms of coping. The background of this doctoral study is provided by earlier research that identified factors influencing repatriates’ adjustment, either positively or negatively. The empirical material of this doctoral thesis comprises twenty-two Phase I semi-structured interviews and ten Phase II follow-up interviews conducted for the purposes of verification. The main findings of the study are formulated as propositions. For instance, it was suggested that repatriates are likely to use different forms of problem-focused strategy more often than various forms of emotion-focused strategy. Moreover, they also are likely to use a larger range of problem-focused strategies than emotion-focused strategies. In addition, in contrast to specialists, repatriates occupying managerial positions are likely to use a greater number and a greater variety of different forms of problem-focused strategy than of emotion-focused strategy, especially in the context of preparing for their return and in different work role changes. This thesis contributes to research on repatriation, expatriation, coping and identifies implications for management.

Magnetorotational instability driven dynamos at low magnetic Prandtl numbers

Numerical simulations of the magnetorotational instability (MRI) with zero initial net flux in a non-stratified isothermal cubic domain are used to demonstrate the importance of magnetic boundary conditions. In fully periodic systems the level of turbulence generated by the MRI strongly decreases as the magnetic Prandtl number (Pm), which is the ratio of kinematic viscosity and magnetic diffusion, is decreased. No MRI or dynamo action below Pm=1 is found, agreeing with earlier investigations. Using vertical field conditions, which allow magnetic helicity fluxes out of the system, the MRI is found to be excited in the range 0.1
