- Quantitative computerized analysis of data from myocardial thallium-201 (201Tl) single-photon emission tomography (SPET) may improve the diagnostic accuracy of coronary heart disease. The reference ranges for post-menopausal women are, however, limited and obtained mainly from patients. To compare reference values from healthy post-menopausal women and to improve the quantitative analysis, 20 women (10 patients with coronary heart disease and previous infarction and 10 age-matched healthy volunteers) were examined immediately post exercise and after a delay. A nine-segment 'bull's-eye' model was used for analysis. At visual evaluation, reproducibility was high (93%), no false-positive results were obtained and in 70% of the patients the SPET was interpreted as abnormal. Using reported reference values for quantitative analysis, all the healthy women had an abnormal result. New reference values based on three different methods of 'normalization' were calculated: the relative activity of segment 3 set to 100%, the segment with the highest activity set to 100% and a least-squares method. They all differed significantly from those that had previously been reported. The frequencies of agreement between visual and quantitative analysis were 84-92% and were highest when segment 3 was used as a reference, but in this case only 40% of the patients with coronary heart disease had an abnormal SPET. Using the least-squares method for handling digital information, the SD of the normal values decreased and 90% of the patients with coronary heart disease were accurately diagnosed. These results provide quantitative digital reference values for healthy post-menopausal women. They verify that quantitative analysis is in diagnostic agreement with visual evaluation, stress the need for local verification of reference ranges and suggest a least-square normalization method for the analysis.

- Programming education is a hot topic in many countries around the world. Also in Sweden this topic has received a lot of attention lately due to formal introduction of programming curriculum as of 2018. Mathematics is one of the subjects that is most affected by the curriculum changes as the government in Sweden has decided that teachers of mathematics are to teach programming in compulsory school in order to support problem-solving in mathematics. Albeit there are some previous research investigating questions related to how programming can enhance mathematics education, for instance in form of the seminal work of Papert through the LOGO language, more research is required that scrutinize how new programming languages, such as visual block programming languages as Scratch can be used for such purposes. It is against such a background this paper present how two teachers that together with 70 pupils in primary school and during the span of two years systematically have explored the use Scratch programming as a mean to learn mathematics. We also report on the teachers’ reflections on what they perceive is learned by the pupils in relation to the didactical methods employed.

Tidskriftsartikel (refereegranskat)abstract
- Failure to achieve a radical resection as well as intraoperative rectal perforation are important risk factors for local recurrence after rectal cancer surgery, but the importance of other intraoperative adverse events for the prognosis is unknown. The aim of this study was to assess the occurrence of intraoperative adverse events during rectal cancer surgery, and to determine whether these were associated with an increased risk of local recurrence.A retrospective population-based cohort study was undertaken, including all patients in Region Västra Götaland, Sweden, who had undergone primary resection surgery for rectal cancer diagnosed between 2010 and 2014, registered in the Swedish Colorectal Cancer Registry. Data were retrieved from the registry and through review of the medical records.In total 1208 patients were included, of whom 78 (6%) developed local recurrence during the follow-up period of at least 5 years. Intraoperative adverse events were common and occurred in 62/78 (79%) of patients with local recurrence compared to 604/1130 (53%) of patients without local recurrence. In multivariate analysis intraoperative adverse events were found to be an independent risk factor for local recurrence of rectal cancer, as were non-radical resection, a high pathological T-stage, the presence of lymph node metastases, type of surgery and refraining from rectal washout during anterior resection and Hartmann´s procedure.Intraoperative adverse events were found to be an independent risk factor for local recurrence of rectal cancer and could possibly be used together with other known risk factors to select patients for intensified postoperative surveillance.

Research on teachers' professional lives : time to build a research network. Paper presented at NERA's 31st Congress, 6-9 March, Copenhagen
- 2003
-
Konferensbidrag (refereegranskat)abstract
- Teachers’ work has during the last ten years gone through great changes. The effects of postmodern society has made the work more and morecomplex and difficult to handle and understand for those involved as well as outsiders. Researchers are trying to keep up with things. The developmentof knowledge of teachers’ work takes place on different levels, in separate disciplines, from various starting-points and with different foci.To be able to describe, understand and explain the »new« work of teachers in a vigorous way there is need of getting these research initiativestogether. Arenas should be established where interchanges and coordination between researchers could take place. In order to make this happen wehave the intention of building a Swedish (our aim is to expand the network to the Nordic countries after the establishment in Sweden) network ofresearch on teachers’ professional lives.Besides presenting the intention and design of our network we also bring along some examples of research projects in line with the network ideas.

Agency and Adaptation : Strategies of Immigrants' Descendants on the Swedish Labor Market
- 2020
-
Ingår i: Nordic Journal of Working Life Studies. - : Roskilde University. - 2245-0157. ; 10:3, s. 43-62
-
Tidskriftsartikel (refereegranskat)abstract
- This article explores how descendants of immigrants in Sweden understand labor market conditions, and how such understandings influence their occupational strategies. We interviewed 21 Sweden-born individuals with non-Western immigrant parents, and identified three strategies based on our analysis of the data: 'choosing' the right job, adapting the habitus, and using cultural capital in flexible ways. The first strategy covers interviewees working in jobs with labor shortages and/or high demand for employees with immigrant background. The second covers interviewees who could learn through failing, with substantial resilience and persistence. The third deals with interviewees who searched for jobs in branches that valued their particular skill set, entailing the importance of being flexible on the labor market.

Door openers? Public officials as supportive actors in the labour market participation of descendants of immigrants in Sweden
- 2021
-
Ingår i: Nordic Social Work Research. - : Taylor & Francis. - 2156-857X .- 2156-8588. ; 11:3, s. 199-212

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to examine how employed descendants of immigrants in Sweden perceive that interactions with public officials have benefitted their occupational aspirations and attainments. We conducted qualitative semi-structured interviews with twelve female and nine male descendants of immigrants, followed by an abductive thematic analysis. Applying a theoretical framework of social capital, we found three main influences of public officials from respondents’ perspectives: 1) connectedness, 2) supporting personal goals and focusing on possibilities, and 3) mediation of knowledge and information. We discuss and analyse the symbolic resources deriving from these influences, e.g. increased motivation and self-belief, and conceptualize these resources as social capital contributing to the occupational aspirations and attainments of immigrants’ descendants.
