- Latent driver sleepiness may in some cases be masked by for example social interaction, stress and physical activity. This short-term modulation of sleepiness may also result from environmental factors, such as when driving in stimulating environments. The aim of this study is to compare two road environments and investigate how they affect driver sleepiness. Thirty young male drivers participated in a driving simulator experiment where they drove two scenarios: a rural environment with winding roads and low traffic density, and a suburban road with higher traffic density and a more built-up roadside environment. The driving task was essentially the same in both scenarios, i.e. to stay on the road, without much interaction with other road users. A 2 x 2 design, with the conditions rural versus suburban, and daytime (full sleep) versus night-time (sleep deprived), was used. The results show that there were only minor effects of the road environment on subjective and physiological indicators of sleepiness. In contrast, there was an increase in subjective sleepiness, longer blink durations and increased EEG alpha content, both due to time on task and to night-time driving. The two road environments differed both in terms of the demand on driver action and of visual load, and the results indicate that action demand is the more important of the two factors. The notion that driver fatigue should be countered in a more stimulating visual environment such as in the city is thus more likely due to increased task demand rather than to a richer visual scenery. This should be investigated in further studies.

- Most people with dementia remain living at home as long as possible after being diagnosed, and hence their lives also include activities in the public space. The aim of this study was to illuminate experiences of accessibility in public space in people with Alzheimer’s disease. A qualitative grounded theory approach with repeated in-depth interviews was used. The core category, accessibility as a constantly changing experience, was characterized by changes in the relationship between informants and public space. Changes in the relationship took place in activities and use of place and related to familiarity and comfort, individual motives and interests, and planning and protecting. Other changes occurred in places and problematic situations related to everyday technologies, crowded places with high tempo and noise, and change of landmarks. These changes reduced feelings of accessibility and increased difficulties in carrying out activities in public space. These findings may be helpful when providing support, and supporting community living.

Citizen science in sweden’s stigmatized neighborhoods
- 2021

Tidskriftsartikel (refereegranskat)abstract
- Based on the synthesis of outside versus inside perspectives, this paper weighs the positive attributes of the so-called deprived place against its negative media image. Applying the concept of territorial stigmatization, small-scale citizen science was conducted to gain a unique understanding of the Swedish neighborhood from within. With the United Nations’ Sustainable Development Goal 11 in mind, this approach enables researchers to reach otherwise difficult to access young urban outcasts and probe the potential to overcome their community’s lack of political influence. An overlap between local media narratives and urban outcasts’ perceptions of “drug and crime” and “football and school” was revealed. Yet, this first-generation study also painted a somewhat different picture of the stigmatized neighborhood, supplying new insights about places that matter most for marginalized young males. In this Swedish case, their pictures revealed that the local corner market, football court and youth club act as an antidote for the effects of stigmatization. This Our Voice citizen science initiative proved to be a good measure of two communities’ abilities to withstand stigmatization, which is either tainted by false perceptions from the outside or weakened by crime from within. Finally, attempting to bypass structural discrimination, citizen scientists’ findings and researchers’ conclusions were made available to students, colleagues and guests at a poster presentation hosted by Mälardalen University and to concerned politicians from Eskilstuna City Hall as well as the broader public via a local Swedish television station.

- Estimating within-city variability in air pollution concentrations is important. Land use regression (LUR) models are able to explain such small-scale within-city variations. Transparency in LUR model development methods is important to facilitate comparison of methods between different studies. We therefore developed LUR models in a standardized way in 36 study areas in Europe for the ESCAPE (European Study of Cohorts for Air Pollution Effects) project.Nitrogen dioxide (NO2) and nitrogen oxides (NOx) were measured with Ogawa passive samplers at 40 or 80 sites in each of the 36 study areas. The spatial variation in each area was explained by LUR modeling. Centrally and locally available Geographic Information System (GIS) variables were used as potential predictors. A leave-one out cross-validation procedure was used to evaluate the model performance.There was substantial contrast in annual average NO2 and NOx concentrations within the study areas. The model explained variances (R2) of the LUR models ranged from 55% to 92% (median 82%) for NO2 and from 49% to 91% (median 78%) for NOx. For most areas the cross-validation R2 was less than 10% lower than the model R2. Small-scale traffic and population/household density were the most common predictors. The magnitude of the explained variance depended on the contrast in measured concentrations as well as availability of GIS predictors, especially traffic intensity data were important. In an additional evaluation, models in which local traffic intensity was not offered had 10% lower R2 compared to models in the same areas in which these variables were offered.Within the ESCAPE project it was possible to develop LUR models that explained a large fraction of the spatial variance in measured annual average NO2 and NOx concentrations. These LUR models are being used to estimate outdoor concentrations at the home addresses of participants in over 30 cohort studies.

The relation between office type and workplace conflict : A gender and noise perspective
- 2015

Tidskriftsartikel (refereegranskat)abstract
- This exploratory study aimed to investigate the impact of the office design on workplace conflicts, with a special attention to noise in the office. A gender perspective was applied. The sample consisted of 5229 employees from the Swedish Longitudinal Occupational Survey of Health 2010 (SLOSH), working in different office types. In the multivariate analysis office type was used as the explanatory variable with adjustments for age, supervisory position and labour market sector. Analysis stratified for gender was used. Among women a significant impact of office type per se on workplace conflicts was found, but not among men. For women several office types differed significantly from the cell-office with regard to prevalence of conflicts during the past two years, but for men only the combi-office differed from the cell-office. Noise had an impact on workplace conflicts, but is not the only explanatory factor since the effect of office type remained also after adjustment for noise in multivariate analyses. Other environmental factors inherent in the office type might thus explain the occurrence of conflicts.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: The incidence of myocardial infarction (MI) has decreased in general but not among younger middle-aged adults. We performed a cohort study of the association between neighbourhood socioeconomic status (SES) at the age of 40 and risk of MI before the age of 50 years. METHODS: All individuals in Sweden were included in the year of their 40th birthday, if it occurred between 1998 and 2010. National registers were used to categorise neighbourhood SES into high, middle and low, and to retrieve information on incident MI and coronary heart disease (CHD). Cox regression models, adjusted for marital status, education level, immigrant status and region of residence, provided an estimate of the HRs and 95% CIs for MI or CHD. RESULTS: Out of 587 933 men and 563 719 women, incident MI occurred in 2877 (0.48%) men and 932 (0.17%) women; and CHD occurred in 4400 (0.74%) men and 1756 (0.31%) women during a mean follow-up of 5.5 years. Using individuals living in middle-SES neighbourhoods as referents, living in high-SES neighbourhoods was associated with lower risk of MI in both sexes (HR (95% CI): men: 0.72 (0.64 to 0.82), women: 0.66 (0.53 to 0.81)); living in low-SES neighbourhoods was associated with a higher risk of MI (HR (95% CI): men: 1.31 (1.20 to 1.44), women: 1.28 (1.08 to 1.50)). Similar risk estimates for CHD were found. CONCLUSIONS: The results of our study suggest an increased risk of MI and CHD among residents from low-SES neighbourhoods and a lower risk in those from high-SES neighbourhoods compared with residents in middle-SES neighbourhoods.

Tidskriftsartikel (refereegranskat)abstract
- Sweden is seen as a typical example of a social democratic welfare regime, with universal and generous welfare policies. However, in the last decades, there have been substantial reductions in the Swedish provision of care for older people. This study aimed to examine trends in sources of care-receipt in older people (77+) living in their own home and with a perceived need for help with two specific tasks: house cleaning and/or food shopping. Trends in care-receipt were examined in relation to gender, living alone, having children and socio-economic position. Data from the 1992, 2002 and 2011 data collection waves of the national study, Swedish Panel Study of Living Conditions of the Oldest Old (SWEOLD), were used. Response rates varied between 86 and 95 per cent, and the sample represents the population well. Trends and differences between groups were explored in bivariate and logistic regression analyses. There was a reduction in formal care-receipt regarding house cleaning and food shopping over the study period. It was more common for women than men to receive formal care, and more common for men than women to receive informal care. Reductions in formal care have affected older women more than older men. Still, living alone was the most influential factor in care-receipt, associated with a greater likelihood of formal care-receipt and a lower likelihood of informal care-receipt. It can be concluded that public responsibility for care is becoming more narrowly defined in Sweden, and that more responsibility for care is placed on persons in need of care and their families.

Is it who you are or where you live? Community effects on net fertility at the onset of fertility decline: A multilevel analysis using Swedish micro-census data

Tidskriftsartikel (refereegranskat)abstract
- This paper studies contextual effects on fertility at the onset of fertility decline in Sweden. We argue that the community exerts an influence on fertility when individuals belonging to a certain community are more similar to one another (within-area) in their reproductive behaviour than individuals living in another community (between-area). Our hypotheses are that community had a strong influence in the past but that it decreased over time as more individualistic values grew in importance. We expect that the community exerted a greater impact in the low socioeconomic groups as the elite were less constrained by proximity and, therefore, more exposed to new ideas crossing community borders. Using micro-census data from 1880, 1890, and 1900, we use multilevel analysis to estimate measures of intra-class correlation within areas. We measure net fertility by the number of own children under five living in the household to currently married women with their spouses present. Parish is used as proxy for community. Our results indicate that despite average differences in fertility across parishes, the correlation between individuals belonging to the same community is less than 2.5%, that is, only a negligible share of the number of children observed is attributable to true community effects. Contrary to our expectation, we do not find any substantial change over time. However, as expected, community has a greater impact in the low socioeconomic groups. Our findings suggest that it is who you are rather than where you live which explains fertility behaviour during the initial stages of the transition
