- DN DEBATT 15/3. Sedan industrialiseringens början har vi använt omkring fyra femtedelar av den mängd fossilt kol som får förbrännas för att vi ska klara Parisavtalet. Vi har bara en femtedel kvar och det är bråttom att kraftigt reducera utsläppen. Det har Greta Thunberg och de strejkande ungdomarna förstått. Därför stödjer vi deras krav, skriver 270 klimatforskare.

- Synergies between large-scale environmental changes, such as climate change1 and increased humic content (brownification)2, will have a considerable impact on future aquatic ecosystems. On the basis of modelling, monitoring and experimental data, we demonstrate that community responses to global change are determined by food-chain length and that the top trophic level, and every second level below, will benefit from climate change, whereas the levels in between will suffer. Hence, phytoplankton, and thereby algal blooms, will benefit from climate change in three-, but not in two-trophic-level systems. Moreover, we show that both phytoplankton (resource) and zooplankton (consumer) advance their spring peak abundances similarly in response to a 3 °C temperature increase; that is, there is no support for a consumer/resource mismatch in a future climate scenario. However, in contrast to other taxa, cyanobacteria—known as toxin-producing nuisance phytoplankton3—benefit from a higher temperature and humic content irrespective of the food-chain composition. Our results are mirrored in natural ecosystems. By mechanistically merging present food-chain theory with large-scale environmental and climate changes, we provide a powerful framework for predicting and understanding future aquatic ecosystems and their provision of ecosystem services and water resources.

Sociala identiteter i seriösa fritidsaktiviteter : - om samspelen mellan seriösa fritidsaktiviteter, platser, sociala världar och konsumtionsföremål i downhillcykling
- 2011

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background This study is about social identity processes within downhill mountain biking. Downhill is portrayed as reflecting the development of consumer culture in today’s society. The development is characterized by the increasing importance of consumption, and social institutions, such as class, family and education, which previously provided individuals with sense of belonging, identity and norms, that are dissolving. Instead, leisure activities offer individuals opportunities to construct social identities. Social identities are defined as the part of the individuals’ identity, which is constructed in interaction with the social categories (identity dimensions) that the he or she belongs to. Four different identity dimensions were considered particularly relevant; serious leisure, places, social worlds and consumer goods. The following main question was raised: How are social identities constructed in interaction with serious leisure, places, social worlds and consumer goods? Method Constructionist grounded theory was used to collect, present, interpret and analyze the empirical information. The empirical study was conducted by active participation in downhill mountain biking (2004-2006) and 38 interviews with mountain bikers in Whistler (Canada) and Åre (Sweden). Results A grounded theory was gradually generated from empirical interpretations into a model of how social identities are constructed in serious leisure activities. The model presents four types of serious leisure participants; new beginners, experienced participants, non-active participants and non-participants. The model is also showing three main groups of sub processes; experience and norm processes, behavioral, physical and verbal identity expressions and the processes of personal investments and benefits. The model also shows three different phases (trial phase, construction/reconstruction phase and disengagement phase) in the participants’ identity processes. Conclusions The participants construct social identities in interaction with the identity dimensions serious leisure, places, social worlds and consumer goods through the processes of experience development, boundary work, leisure career, imitation, norm processes, personal investments and benefits, and behavioral, physical and verbal identity expressions. The participants’ identity processes are dynamic, where the personal investments and benefits of the participants are creating movements between the more stable identity phases formed by the experience- and norm processes, and the different identity expressions.

- Introduction: Life after stroke is a comprehensive area that involves engagement in meaningful everyday activities, including work, and can be adversely affected by post-stroke fatigue. This study investigates post-stroke fatigue, its development over time, and its impact on return to work and other everyday life activities. In addition, we investigated whether post-stroke fatigue could predict functioning in everyday life activities one year after stroke.Material and methods: This prospective registry-based study includes 2850 working age (18 - 63 years) patients registered in the Swedish Stroke Register (Riksstroke) during year 2017 and 2018. Post-stroke fatigue and everyday activities were analyzed 3- and 12-months post-stroke.Results: The mean age of the included participants was 54 years and the majority, 65%, were men. Three months post-stroke, 43% self-reported fatigue, at 12-months the proportion increased to 48%. About 90% of the patients were independent in basic ADL at 3-month. Dependence in complex activities one year post-stroke was significantly associated with fatigue. Not experiencing fatigue one year after stroke could predict positive functioning in everyday activities, increasing the chance of returning to work (OR = 3.7) and pre-stroke life and everyday activities (OR = 5.7).Conclusion: Post-stroke fatigue is a common persistent disability that negatively impacts complex activities; therefore, fatigue needs to be acknowledged and addressed long term after discharge.
