- Recreational fishing has grown substantially worldwide; for some recreational fisheries both catch and economic value now exceeds that of commercial fisheries. Monitoring of recreational fisheries effort and catch is therefore important for sustainable fisheries management. We developed and implemented an angler survey to estimate effort and catch for the recreational trolling fishery for landlocked Atlantic salmon (Salmo salar) and brown trout (S. trutta) in Lake Vänern, Sweden. Major challenges were the large spatial scale and dispersed fishing effort, a lack of revenue from fishing licence sales, and a lack of catch reporting requirements. We developed a complemented roving/mail-in survey to estimate effort and catch during the main fishing periods, spring and fall, 2014. Instantaneous counts from major access sites were used for effort estimates, and mail-in surveys were used for catch rates. Our results show that Vänern supports a salmon and trout fishery of some 28.7 ± 3.3 tonnes per year. Fishing effort was higher in the spring than in the fall, and there were seasonal differences in catch rates for trout but not for salmon. Estimates show that the recreational trolling fishery now harvests more salmon and trout annually than do the commercial and subsistence fisheries combined. This highlights the importance of continuing an angler survey program for Vänern as a key element for sustainable fisheries management, and can serve as a model for other recreational fisheries at large spatial scales.

Tidskriftsartikel (refereegranskat)abstract
- A Swedish radon data set, consisting of more than 8000 measurements of residential radon levels in about 50% of the Swedish municipalities were analysed using a multilevel approach.The results were compared with those of a single-level analysis. We found that there was a significant variability between municipalities. The point estimates of the population mean radon levels were similar (geometric mean 60 Bq/m3 and arithmetic mean 106 Bq/m3).The analysis shows the advantages of multilevel modeling compared with a single-level OLS model.A single-level model results in too optimistic standard errors, about 25% of those of the multilevelmodel which can lead to erroneous conclusions.In a multilevel model including house type as a fixed effect (single-family house, row house, or apartment in multi-family house), the estimates of the fixed effect of house type were similar for the single-level and the multi-level models

Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The curricula that defines special needs education in Swedish grammar schools states that students with intellectual disabilities should be given the possibility to participate in the planning and shaping of teaching and learning activities. The purpose of the study is to examine conditions regarding special needs students’ influence and how this influence is mediated. The focus of the study is subject based classroom situations. The method for collecting data has been observations. The empirical data consists of around 16 hours of video recordings, in addition to field notes. The observations took place in two special schools and all together 10 pupils, 5 teachers, and two student assistants participated. The theoretical framework is based on sociocultural theory with a specific focus on mediation. By using the theoretical terms object and subject positioning, the study also focuses on how teachers and students position themselves and each other. The results show that the students with intellectual disabilities are given opportunities for influence, but not very frequently. The most important mediating factors to promote influence are the teachers´ trust in the students´ abilities and skills, and the teacher’s keen responsiveness to the students’ expressed personal will. Influence is mediated both through the possibilities of participation that teachers offer, and the teachers’ affirmation of the students’ requests. Furthermore, the study shows that students are more likely to gain influence in one-to-one meetings with the teacher, where the focus is on the student’s individual interests and preferences. In order to provide increased levels of influence to all students with intellectual disabilities, teachers need to plan the education with focus on democratic processes.

Older people's perceptions of the quality of oral care in short-term care units : A cross-sectional study

- Background: There is a lack of knowledge about oral care among older people living in short-term care (STC) units and how the quality of oral care provided by nursing staff is perceived by the older people. Aim: To (i) describe person-related conditions among older people in STC, (ii) describe and compare perceptions of the quality of oral care (including perceptions of care received and the subjective importance of such care), within and between older people who have the ability to perform oral self-care and those who are dependent on help with oral care and (iii) examine the relationship between person-related conditions and the quality of oral care. Methods: A cross-sectional study was conducted with 391 older people in STC units in Sweden based on self-reported questionnaire and clinical assessments. Results: The older people were assessed as having normal oral health (2%), moderate oral health problems (78%) or severe oral health problems (20%). When comparing older people's perceptions of quality of oral care in terms of perceived reality and subjective importance, significant differences appeared within and between groups. Psychological well-being had a significant relationship with perception of the quality of oral care (both perceived reality and subjective importance), and gender and oral health status had a significant relationship with subjective importance. Conclusions: Older people's perceptions of areas for improvement regarding quality of oral care is a new and important knowledge for nursing staff in STC units. Older people want personalised information regarding oral health and oral care. Registered Nurses who take the responsibility in nursing care for older people's oral health may avoid unnecessary suffering by older people caused by oral health problems. Implications for practice: Older people's perspective is an important component for quality work and might lead to improvements in the quality of oral care in STC. © 2018 John Wiley & Sons Ltd.
