- Aquaculture is essential for meeting the growing global demand for fish consumption. However, the widespread use of plastic and the presence of microplastics in aquaculture systems raise concerns about their impact on fish health and the safety of aquaculture products. This study focused on the Nile tilapia (Oreochromis niloticus), one of the most important aquaculture fish species globally. The aim of this study was to investigate the effects of dietary exposure to a mixture of four conventional fossil fuel-based polymers (microplastics) on the health of adult and juvenile Nile tilapia. Two experiments were conducted, with 36 juvenile tilapia (10–40 g weight) exposed for 30 days and 24 adult tilapia (600–1000 g) exposed for 7 days, the former including a natural particle (kaolin) treatment. In the adult tilapia experiment, no significant effects on intestinal health (Ussing chamber method), oxidative stress, or inflammatory pathways (enzymatic and genetic biomarkers) were observed after exposure to the microplastic mixture. However, in the juvenile tilapia experiment, significant alterations in inflammatory pathways were observed following 30 days of exposure to the microplastic mixture, indicating potential adverse effects on fish health. These results highlight the potential negative impacts of microplastics on fish health and the economics and safety of aquaculture.

Career histories as determinants of gendered retirement timing in the Danish and Swedish pension systems

- © 2017 The Author(s) After reforms in pension systems had taken place in most European countries within the last two decades, the concern was raised that women may be disadvantaged by these reforms. It is suggested that they are faced with a higher financial need to work longer. Retrospective data from SHARELIFE are used to run an event history analysis on the timing of the final employment exit, separately for gender, country and exit cohort. This study aims to disentangle the influence of gendered labour markets and pension regulations on retirement timing by investigating conditions in Denmark and Sweden. Some evidence was found that women compensate for lower labour market attachment due to long part-time periods by working longer, especially in younger cohorts. This seems to depend on the pension system. In countries with broad basic pensions, high replacement rates for low-income groups and fewer penalties for early retirement, the compensation is suggested to be less frequent. This study indicates the growing importance of the “compensation hypothesis” compared to the “status maintenance hypothesis” of previous careers in relation with retirement timing.

Development of healthcare use across contemporary retirement pathways : results from a register based cohort study

- Aim: We aimed to understand the interplay between retirement pathways and healthcare use in the postponed and structurally changing context of retirement.Methods: Based on Swedish register data on income and healthcare use, we applied combined sequence and cluster analysis to identify typical pathways into retirement and analysed their relation to healthcare use developments.Results: We detected five distinct pathways into retirement. Level of healthcare use was significantly higher for the pathway via disability pensions. We saw an overall increase in healthcare use across the retirement process that was related to age rather than to the different pathways.Conclusions: Level of healthcare use at the beginning of the retirement process may be related to selection into different pathways of retirement. We did not find clear evidence across several healthcare measures that different pathways lead to different developments in healthcare use.

Gendered division of housework in Germany The role of self-employment, relative resources and gender role orientation

Tidskriftsartikel (refereegranskat)abstract
- The purpose of this paper is to investigate the division of housework within couples in Germany by taking employment status, relative resources and gender role orientation into consideration. We use a large scale primary data collection that deliberately oversampled self-employed and included questions on role orientation. While self-employment and work autonomy was related to a lower share of housework for men, rather the opposite was true for women. Furthermore, the results indicate that the relative resources and bargaining theory and the time budget approach seem to be less relevant for female self-employed compared to their employed counterparts. Our data allowed for a direct control of the gender role orientation and shed more light on the relationship between relative resources and the share of housework. A traditional role orientation was found to be highly significant for the share of housework for men and women but did not moderate the effect of relative resources. Thereby our study supports the distinct effect of gender role orientation. This can be seen as an important contribution to the ongoing discussion where relative resources are interpreted in the light of gender role orientation.

Invisible Scars or Open Wounds? The Role of Mid-career Income for the Gender Pension Gap in Sweden
- 2019

Tidskriftsartikel (refereegranskat)abstract
- This study investigates the importance of mid-career income for the gender pension gap and psychological scarring effects of low income earlier in life. More specifically we analyse whether women's typically less stable mid-life careers also affect outcomes in late careers and in retirement. Swedish income register data from 1990, 2009, and 2015 was linked to the “HEalth, Ageing, and Retirement Transitions in Sweden” survey. The gender pension gap of 966 retirees and worries about pension income of 2,723 older workers between the age of 60 and 66 years were investigated. Blinder-Oaxaca decompositions were applied to analyse the gender pension gap and linear regressions were used for the analysis of financial worries. Results show that gender differences in mid-career income play a stronger role for the gender pension gap than late career income. Mid-career income is furthermore related to higher worries about pension income and accounts for observed gender differences. Our findings demonstrate that gender gaps in mid-career income can be regarded as an open wound with visible negative effects in older ages. The reformed pension system in Sweden may potentially contribute to an even greater gender gap in pensions.

Involuntary and Delayed Retirement as a Possible Health Risk for Lower Educated Retirees
- 2019

Tidskriftsartikel (refereegranskat)abstract
- Recent changes in the pension system may contribute to larger social inequalities and more involuntary late retirement transitions due to financial need. Lower educated workers may have less control over their retirement and may need to stay in the labour market despite poor health. How different aspects of the retirement transitions are related to post-retirement health is unclear. This study investigates health differences across educational levels among 1280 retirees participating in the ‘Health, Ageing and Retirement Transitions in Sweden’ (HEARTS) study. Retirement age and involuntary reasons for retirement were considered as potential mediator and moderators of the social gradient in health outcomes. Results from a path analysis suggest that lower educated retirees are more likely to stop working for physical reasons, which is related to poor post-retirement health. Hence, involuntary retirement mediates the educational effect on health. Linear regressions highlighted the moderating effect of retirement age: lower educated retirees had worse health than higher educated retirees when their transitions were late. Hence, the double disadvantage of lower educated individuals becomes apparent. This study contributes to explaining possible mechanisms of rising health inequalities by focusing on aspects of retirement.
