- It has been suggested that volunteering leads to increases in well-being, particularly in older and retiring adults, and that volunteering could be used as a public health intervention to increase well-being. However, the causal relationship has been questioned. We investigated the association between voluntary work and life satisfaction in a bivariate dual-change score model, using 4 years of longitudinal data from 1,123 participants from the Health, Aging and Retirement Transitions in Sweden (HEARTS) study. Both the frequency of volunteering and the level of life satisfaction increased across the retirement transition. However, baseline life satisfaction and volunteering were only marginally associated. Further, the coupling parameters suggest that higher levels of volunteering were followed by decreases in life satisfaction and that higher levels of life satisfaction were followed by increases in volunteering. These findings suggest that increasing levels of volunteering might not be a fruitful strategy for improving life satisfaction for all older adults-if people engage too much in voluntary work, it might even be detrimental for their life satisfaction. More research is needed to better understand when and for whom increased levels of volunteering might have positive effects on life satisfaction.

Samlingsverk (redaktörskap) (refereegranskat)abstract
- Accounts of Lease Entrance Fees for Jämtland and Härjedalen 1601–1645. Edited by Georg Hansson and Olof Holm. With an index of place-names by Karl Göran Eriksson.This is an edition, with commentary, of a series of accounts of lease entrance fees for the provinces of Jämtland and Härjedalen, dating from 1601 to 1645. Jämtland and Härjedalen are today parts of Sweden, but belonged to Norway until 1645. During the period in question, Norway was part of the Danish-Norwegian state.The present accounts were made by the bailiffs serving in Jämtland and Härjedalen. They report an entrance fee called bygsel collected by the bailiffs when they let out crown land and so-called avradsland, i.e. divided parts of the common land, on lease to individuals. The quantity of crown land in Jämtland dramatically increased from about 4% to 69% of all land after the Kalmar War of 1611–13, when most of the farmers in this province lost their land to the Danish-Norwegian King Kristian IV. The bailiffs were subordinate to the feudal lord residing in Trondheim, who had the right to a share of the entrance fees collected. The rest of the entrance fees went, together with the accounts and other revenues and records as well, to the King’s treasury in Copenhagen. Today all these records are kept in the national archives of Sweden and Norway.In the introduction, Olof Holm describes and discusses the contents of the accounts, the lease agreements they deal with, the conditions for the leaseholders, the vast growth of crown land in Jämtland during the period, along with other subjects. In the main part of the edition all text of the bygsel accounts is transcribed. Two appendices are included: 1) excerpts from preserved letters describing leasehold agreements from the period, and 2) testimonies concerning the bailiffs’ collecting of bygsel fees. The book ends with indices of place-names and officials, and a word list.

Tidskriftsartikel (refereegranskat)abstract
- Objective: Research on retirement suggests that personality can influence the adjustment process, but the mechanisms involved remain still largely unknown. In the present study, we investigate direct and indirect associations between the Big Five personality traits and life satisfaction over the retirement transition. Indirect effects were evaluated through the role of personality for levels and changes in self‐esteem, autonomy, social support, self‐rated physical health, self‐rated cognitive ability, and financial satisfaction. Method: Our sample consisted of 796 older adults (age 60–66) and four annual measurement waves from the longitudinal population‐based HEalth, Ageing, and Retirement Transitions in Sweden (HEARTS) study, including individuals retiring during the study period. Results: Results from multivariate latent growth curve analysis revealed multiple indirect associations between personality and life satisfaction. Extraversion, Agreeableness, and Conscientiousness were positively related to life satisfaction through higher levels of self‐esteem, autonomy, and social support. Neuroticism was negatively associated with life satisfaction through lower levels of self‐esteem and lower levels and negative changes in autonomy and social support. Conclusions: Our findings suggest that retirees with higher levels of Neuroticism are more vulnerable in the transition process and they are also more likely to experience adjustment problems resulting from negative changes in key resources.

Do neuroticism and conscientiousness interact with health conditions in predicting 4-year changes in self-rated health among Swedish older adults?

Tidskriftsartikel (refereegranskat)abstract
- Health conditions such as higher disease burden, pain, or lower functional health are associated with poorer self-rated health (SRH) in older age. Poorer SRH, in turn, is a predictor of morbidity and mortality. Personality traits are associated with SRH as well, but little is known about the interaction of personality and health conditions. In the present preregistered analyses, we used five annual waves of the Health, Aging and Retirement Transitions in Sweden (HEARTS) study (N = 5,823, M age = 63.09, SD = 2.01) to investigate the associations of personality (neuroticism and conscientiousness) and physical health indices (disease burden, pain, and functional limitations) with levels and change in SRH. In addition, we tested Personality × Health interaction effects. We found that higher neuroticism and lower conscientiousness were related to lower levels of SRH, but not to change in SRH after controlling for the health indices. Personality did not moderate the effect of health indices on levels and change in SRH. Exploratory analyses showed that high scores of neuroticism may augment the association of increased pain and functional limitations with declines in SRH. Additional studies with other samples are needed to test if this result can be replicated. Taken together, our findings provide only weak evidence for interaction effects of personality and physical health factors on SRH. More research is needed to understand the interplay of physical and psychological factors in shaping individual SRH. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

- Cultivated oat (Avena sativa L.) is an allohexaploid (AACCDD, 2n = 6x = 42) thought to have been domesticated more than 3,000 years ago while growing as a weed in wheat, emmer and barley fields in Anatolia1,2. Oat has a low carbon footprint, substantial health benefits and the potential to replace animal-based food products. However, the lack of a fully annotated reference genome has hampered efforts to deconvolute its complex evolutionary history and functional gene dynamics. Here we present a high-quality reference genome of A. sativa and close relatives of its diploid (Avena longiglumis, AA, 2n = 14) and tetraploid (Avena insularis, CCDD, 2n = 4x = 28) progenitors. We reveal the mosaic structure of the oat genome, trace large-scale genomic reorganizations in the polyploidization history of oat and illustrate a breeding barrier associated with the genome architecture of oat. We showcase detailed analyses of gene families implicated in human health and nutrition, which adds to the evidence supporting oat safety in gluten-free diets, and we perform mapping-by-sequencing of an agronomic trait related to water-use efficiency. This resource for the Avena genus will help to leverage knowledge from other cereal genomes, improve understanding of basic oat biology and accelerate genomics-assisted breeding and reanalysis of quantitative trait studies.

- The amyloid cascade hypothesis, according to which the self-assembly of amyloid-β peptide (Aβ) is a causative process in Alzheimer’s disease, has driven many therapeutic efforts for the past 20 years. Failures of clinical trials investigating Aβ-targeted therapies have been interpreted as evidence against this hypothesis, irrespective of the characteristics and mechanisms of action of the therapeutic agents, which are highly challenging to assess. Here, we combine kinetic analyses with quantitative binding measurements to address the mechanism of action of four clinical stage anti-Aβ antibodies, aducanumab, gantenerumab, bapineuzumab and solanezumab. We quantify the influence of these antibodies on the aggregation kinetics and on the production of oligomeric aggregates and link these effects to the affinity and stoichiometry of each antibody for monomeric and fibrillar forms of Aβ. Our results reveal that, uniquely among these four antibodies, aducanumab dramatically reduces the flux of Aβ oligomers.

- The Zeppelin Observatory (78.90∘ N, 11.88∘ E) is located on Zeppelin Mountain at 472 m a.s.l. on Spitsbergen, the largest island of the Svalbard archipelago. Established in 1989, the observatory is part of Ny-Ålesund Research Station and an important atmospheric measurement site, one of only a few in the high Arctic, and a part of several European and global monitoring programmes and research infrastructures, notably the European Monitoring and Evaluation Programme (EMEP); the Arctic Monitoring and Assessment Programme (AMAP); the Global Atmosphere Watch (GAW); the Aerosol, Clouds and Trace Gases Research Infrastructure (ACTRIS); the Advanced Global Atmospheric Gases Experiment (AGAGE) network; and the Integrated Carbon Observation System (ICOS). The observatory is jointly operated by the Norwegian Polar Institute (NPI), Stockholm University, and the Norwegian Institute for Air Research (NILU). Here we detail the establishment of the Zeppelin Observatory including historical measurements of atmospheric composition in the European Arctic leading to its construction. We present a history of the measurements at the observatory and review the current state of the European Arctic atmosphere, including results from trends in greenhouse gases, chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), other traces gases, persistent organic pollutants (POPs) and heavy metals, aerosols and Arctic haze, and atmospheric transport phenomena, and provide an outline of future research directions.

Towards an assessment of safety and security interplay in automated driving systems.
- 2022
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- We are currently in the midst of significant changes in the road transport system, including the transformation to fossil-free propulsion and the shift to higher levels of automation. The next level in automation is soon upon us and is encompassed by the broader term Connected, Cooperative and Automated Mobility (CCAM) which is relevant for the entire transportation system. The introduction of CCAM has the potential to contribute significantly to crucial UN Sustainable Development Goals. For the automotive domain, the term Automated Driving Systems (ADS) is often used for highly automated vehicles. Notwithstanding the expected positive effects and the extraordinary efforts, highly automated driving systems are still not publicly available except in pilot programs.The increased complexity in the higher automation levels can be ascribed to the shift from fail-safe operator support to fail-operational systems that assume the operator's role, utilising new sensors and algorithms for perception and the reliance on connectivity to solve the problem task. Here the solution is also the problem, i.e. complex systems. The complexity of the systems and difficulties in capturing a complete practical description of the environment where the systems are intended to operate pose difficulties in defining validation procedures for ADS technologies' safety, security, and trustworthiness.Parallel to traditional safety issues, there is now a need to consider the quality of cybersecurity, e.g. due to external communication and environmental sensors being susceptible to remote attacks. A security problem may enable a hacker to incapacitate or fool an ADS resulting in unsafe behaviour. In addition to malicious misuse, the development of environment sensing has to consider functional insufficiencies of the employed sensor technologies. Therefore, both safety and security and their interplay must be addressed in developing the solutions.The first step in gaining public confidence in the technologies involved is to raise user awareness. Therefore there is a need to be transparent and explicit on the evaluation targets and the associated supporting evidence of safe and secure ADS. An assessment of safety and security properties performed by an independent organisation can be an essential step towards establishing trust in ADS solutions, bridging the gap between the marketing portrayal and the actual performance of such systems in operating conditions.This licentiate thesis contributes towards the overall goal of improving the assessment target and the associated supporting evidence of a safe and secure ADS in the automotive domain by (1) assessing requirements for safety, security and their interplay on key enabling technologies, (2) introducing an argument pattern enabling safety, security and interaction overlap to be jointly addressed, (3) proposing a method that enables assessment of security informed safety an independent agency.
