- Differences between office types may have an influence on the employees' satisfaction and psychological responses with respect to different aspects of the office environment. For this study, 469 employees rated their perceptions of and satisfaction with the office environments of seven different office types, which were classified as cell-office, shared-room office, small open-plan office, medium open-plan office, large open-plan office, flex-office, and combi-office. Three domains of environmental factors were analyzed: (1) ambient factors, (2) noise and privacy, and (3) design-related factors. Employee responses were evaluated using multivariate logistic and Poisson regression., Adjustments were made for potential confounders such as age, gender job rank, and line of business. Substantial differences between employees in different office types were found The analysis of frequencies in complaints within the three domains shows that noise and privacy is the domain that causes the most dissatisfaction among office employees. Cell-office employees are most satisfied with the physical environment overall, followed by those in flex-office. However the results for cell-office are not uniformly best, since they score low with regard to the social aspects of design-related factors and, in particular on support of affinity. The most dissatisfaction is reported in medium and large open-plan offices, where the complaints about noise and lack of privacy are especially negative. Architectural and functional features of the offices are discussed as the main explanatory factors for these results.

- This article investigates the hypothesis that office type has an influence on workers’ health status and job satisfaction and 469 employees in seven different types, defined by their unique setup of architectural and functional features, have rated their health status and job satisfaction. Multivariate regression models were used for analysis of these outcomes, with adjustment for age, gender, job rank, and line of business. Both health status and job satisfaction differed between the seven office types. Lowest health status was found in medium-sized and small open plan offices. Best health was among employees in cell offices and flex offices. Workers in these types of offices and in shared room offices also rated the highest job satisfaction. Lowest job satisfaction was in combi offices, followed by medium-sized open plan offices. The differences between employees could possibly be ascribed to variations in architectural and functional features of the office types.

- Forestry is continually changing the habitats for many forest-dwelling species around the world. The grey-sided vole (Myodes rufocanus) has declined since the 1970s in forests of northern Sweden. Previous studies suggested that this might partly be caused by reduced focal forest patch size due to clear-cutting. Proximity and access to old pine forest and that microhabitats often contains stones have also been suggested previously but never been evaluated at multiple spatial scales. In a field study in 2010–2011 in northern Sweden, we investigated whether occurrence of grey-sided voles would be higher in (1) large focal patches of >60 years old forest, (2) in patches with high connectivity to sur- rounding patches, and (3) in patches in proximity to stone fields. We trapped animals in forest patches in two study areas (V€asterbotten and Norrbotten). At each trap station, we surveyed structural microhabitat characteristics. Land- scape-scale features were investigated using satellite-based forest data combined with geological maps. Unexpectedly, the vole was almost completely absent in Norrbotten. The trap sites in Norrbotten had a considerably lower amount of stone holes compared with sites with voles in V€asterbotten. We suggest this might help to explain the absence in Norrbotten. In V€asterbotten, the distance from forest patches with voles to stone fields was significantly shorter than from patches without voles. In addition, connectivity to surrounding patches and size of the focal forest patches was indeed related to the occurrence of grey-sided voles, with connectivity being the overall best predictor. Our results support previous findings on the importance of large forest patches, but also highlight the importance of connectivity for occurrence of grey-sided voles. The results further suggest that proximity to stone fields increase habitat quality of the forests for the vole and that the presence of stone fields enhances the voles’ ability to move between nearby forest patches through the matrix

- Ensembles of independently trained deep neural networks yield uncertainty estimates that rival Bayesian networks in performance. They also offer sizable improvements in terms of predictive performance over single models. However, deep ensembles are not commonly used in environments with limited computational budget - such as autonomous driving - since the complexity grows linearly with the number of ensemble members. An important observation that can be made for robotics applications, such as autonomous driving, is that data is typically sequential. For instance, when an object is to be recognized, an autonomous vehicle typically observes a sequence of images, rather than a single image. This raises the question, could the deep ensemble be spread over time?In this work, we propose and analyze Deep Ensembles Spread Over Time (DESOT). The idea is to apply only a single ensemble member to each data point in the sequence, and fuse the predictions over a sequence of data points. We implement and experiment with DESOT for traffic sign classification, where sequences of tracked image patches are to be classified. We find that DESOT obtains the benefits of deep ensembles, in terms of predictive and uncertainty estimation performance, while avoiding the added computational cost. Moreover, DESOT is simple to implement and does not require sequences during training. Finally, we find that DESOT, like deep ensembles, outperform single models for out-of-distribution detection.

- Short-term exposure to dust and dust added with beta-(1,3)-d-glucan or aldehydes may cause sensory reactions. In random order, we exposed 36 volunteers in a climate chamber to clean air, office dust, dust with glucan, and dust with aldehydes. Three groups of subjects were exposed, eleven were non-atopic with nasal histamine hyperreactivity, 13 were non-atopic, and 12 were atopic. Subjective ratings of symptoms and general health were registered four times during four 6-h exposure sessions. Six symptom intensity indices were constructed. The nasal hyperreactive group had a high and time-dependent increase of mucous membrane irritations, whereas the atopic group had a low and stable rate of irritations with exposure time, close to the reference group (P = 0.02 for differences between the groups with respect to time under exposure for Weak Inflammatory Responses and P = 0.05 for Irritative Body Perception, significance mainly because of the nasal hyperreactive group). Exposure to dust, with or without glucan or aldehydes, showed increased discomfort measured by the index for Constant Indoor Climate, and dust with glucan had a similar effect for the index for Lower Respiratory Effects. For Psychological and Neurological Effects these were dependent on group affiliation, thus preventing a uniform statement of exposure effects for all three investigated groups.Opportunities for identifying persons with high or low sensitivity to low-level exposures are important in preventive medicine and will reduce intra-group variability and thus increase the power of experimental and epidemiological studies searching for correlations between exposures and health effects. The contrast between nasal hyperreactive on one side and atopic and reference subjects on the other side is particularly important. The atopic group indicated a non-homogenous reaction depending on their hyperreactive status, a finding that could be important but needs further confirmation.

Tidskriftsartikel (refereegranskat)abstract
- Background: Despite previous efforts to understand temperament in children with intellectual disability (ID), and how child temperament may affect parents, the approach has so far been unidimensional. Child temperament has been considered in relation to diagnosis, with the inherent risk of overlooking individual variation of children’s temperament profiles within diagnostic groups. The aim of the present study was to identify temperamental profiles of children with ID, and investigate how these may affect parents in terms of positive and negative impacts. Method: Parent-rated temperament in children with ID was explored through a personoriented approach (cluster analysis). Children with ID (N = 49) and typically developing (TD) children (N = 82) aged between 4 and 6 years were clustered separately. Results: Variation in temperament profiles was more prominent among children with ID than in TD children. Out of the three clusters found in the ID group, the disruptive, and passive/withdrawn clusters were distinctly different from clusters found in the TD group in terms of temperament, while the cluster active and outgoing was similar in shape and level of temperament ratings of TD children. Children within the disruptive cluster were described to have more negative and less positive impacts on mothers compared to children within the other clusters in the ID group. Conclusions: Mothers who describe their children as having disruptive temperament may be at particular risk for experiencing higher parenting stress as they report that the child has higher negative and lower positive impacts than other parents describe. The absence of a relationship between child temperament profile and positive or negative impact on fathers may indicate that fathers are less affected by child temperament. However, this relationship needs to be further explored.

Forskningsöversikt (refereegranskat)abstract
- Objectives: We conducted a systematic literature review to identify studies fulfilling good scientific epidemiological standards for use in meta-analyses of occupational risk factors for amyotrophic lateral sclerosis (ALS). Methods: We identified 79 original publications on associations between work and ALS. The MOOSE (Meta-analysis Of Observational Studies in Epidemiology) and GRADE (Grading of Recommendations, Assessment, Development and Evaluations) guidelines were used to ensure high scientific quality, and reliable protocols were applied to classify the articles. Thirty-seven articles fulfilled good scientific standards, while 42 were methodologically deficient and thus were excluded from our meta-analyses. Results: The weighted relative risks for the various occupational exposures were respectively; 1.29 (95% confidence interval (CI): 0.97⁻1.72; six articles) for heavy physical work, 3.98 (95% CI: 2.04⁻7.77; three articles) for professional sports, 1.45 (95% CI: 1.07⁻1.96; six articles) for metals, 1.19 (95% CI: 1.07⁻1.33; 10 articles) for chemicals, 1.18 (95% CI: 1.07⁻1.31; 16 articles) for electromagnetic fields or working with electricity, and 1.18 (95% CI: 1.05⁻1.34; four articles) for working as a nurse or physician. Conclusions: Meta-analyses based only on epidemiologic publications of good scientific quality show that the risk of ALS is statistically significantly elevated for occupational exposures to excessive physical work, chemicals (especially pesticides), metals (especially lead), and possibly also to electromagnetic fields and health care work. These results are not explained by publication bias.

- Objectives: To carry out an integrated and stratified meta-analysis on occupational exposure to electromagnetic fields (EMFs), metals and pesticides and its effects on amyotrophic lateral sclerosis (ALS) and Parkinson's and Alzheimer's disease, and investigate the possibility of publication bias.Methods: In the current study, we updated our recently published meta-analyses on occupational exposures in relation to ALS, Alzheimer's and Parkinson's disease. Based on 66 original publications of good scientific epidemiological standard, according to the Meta-analysis of Observational Studies in Epidemiology (MOOSE) and the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) guidelines, we analysed subgroups by carrying out stratified meta-analyses on publication year, statistical precision of the relative risk (RR) estimates, inspection of the funnel plots and test of bias.Results: Based on 19 studies the weighted RR for occupational exposure to EMFs was 1.26 (95% confidence interval (CI) 1.07-1.50) for ALS, 1.33 (95% CI 1.07-1.64) for Alzheimer's disease and 1.02 (95% CI 0.83-1.26) for Parkinson's disease. Thirty-one studies concerned occupational exposure to pesticides and the weighted RR was 1.35 (95% CI 1.02-1.79) for ALS, 1.50 (95% CI 0.98-2.29) for Alzheimer's disease and 1.66 (95% CI 1.42-1.94) for Parkinson's disease. Finally, 14 studies concerned occupational exposure to metals and only exposure to lead (five studies) involved an elevated risk for ALS or Parkinson's disease and the weighted RR was 1.57 (95% CI 1.11-2.20). The weighted RR for all the non-lead exposures was 0.97 (95% CI 0.88-1.06).Conclusions: Exposure to pesticides increased the risk of getting the mentioned neurodegenerative diseases by at least 50%. Exposure to lead was only studied for ALS and Parkinson's disease and involved 50% increased risk. Occupational exposure to EMFs seemed to involve some 10% increase in risk for ALS and Alzheimer's disease only.
