  • Utvärdering av metoder mot mobbning
  • 2011
  • Rapport (övrigt vetenskapligt)abstract
    • Denna utvärdering ger besked om insatser och arbetssätt som effektivt förebygger och åtgärdar mobbning. Utvärderingen är unik genom att den omfattar stora mängder data, både kvalitativa och kvantitativa från 39 skolor, att enskilda individers utsatthet följs upp vid tre tillfällen och att den omfattar flera program samtidigt.Resultaten visar bland annat att olika insatser har olika effekt för pojkar och flickor samt olika effekt beroende på om mobbningen är social eller fysisk. Den visar också att ingen enskild insats har dramatiskt positiva effekter. För att en skola ska lyckas förebygga och åtgärda mobbning krävs ett systematiskt arbete och en kombination av insatser. Åtta namngivna program som används mot mobbning har ingått i utvärderingen: Farstametoden, Friends, Lions Quest, Olweusprogrammet, SET - Social och emotionell träning, Skolkomet, Skolmedling samt Stegvis. I utvärderingens fristående metodfördjupning Utvärdering av metoder mot mobbning. Metodappendix och bilagor till rapport 353, (endast publicerad som pdf ) redovisar forskarna utförligt utvärderingens design och redogör för tillvägagångssättet vid datainsamling och analys.

  • 1897 : Mediehistorier kring Stockholmsutställningen
  • 2006
  • Samlingsverk (redaktörskap) (övrigt vetenskapligt)abstract
    • När börjar mediehistorien? Mediehistoria var länge liktydigt med historien om 1900-talets massmedier  press, radio, teve och film. I den här boken skildras istället ett äldre medielandskap. Med utgångspunkt i Stockholmsutställningen 1897 beskriver författarna det utbud av gamla och nya medier som samlades på utställningen, från äldre attraktioner som camera obscura, dioramor och vaxfigurer till spektakulära nyheter som fonograf, kinematograf och röntgenbilder. Boken ger inblickar i några av det sena 1800-talets ledande medieindustrier, och diskuterar bland annat frågor om mediekonsumtion, publikpositioner och historiska medieringsvillkor. De medietekniker som presenterades på Stockholmsutställningen 1897 lagrade på samma gång utställningen för framtiden. Ett centralt tema är därför hur dessa medieringar blivit identiska med minnet av utställningen, och hur detta arkiv organiserats utifrån mediernas specifika egenskaper. På den DVD-skiva som medföljer boken har ett nytt mediearkiv skapats över Stockholmsutställningen 1897 och dess många länkar till en bredare mediekultur.

  • A quality assessment survey of SNP genotyping laboratories
  • 2006
  • Ingår i: Human Mutation. - 1059-7794. ; 27:7, s. 711-714
  • Tidskriftsartikel (övrigt vetenskapligt)abstract
    • To survey the quality of SNP genotyping, a joint Nordic quality assessment (QA) round was organized between 11 laboratories in the Nordic and Baltic countries. The QA round involved blinded genotyping of 47 DNA samples for 18 or six randomly selected SNPs. The methods used by the participating laboratories included all major platforms for small- to medium-size SNP genotyping. The laboratories used their standard procedures for SNP assay design, genotyping, and quality control. Based on the joint results from all laboratories, a consensus genotype for each DNA sample and SNP was determined by the coordinator of the survey, and the results from each laboratory were compared to this genotype. The overall genotyping accuracy achieved in the survey was excellent. Six laboratories delivered genotype data that were in full agreement with the consensus genotype. The average accuracy per SNP varied from 99.1 to 100% between the laboratories, and it was frequently 100% for the majority of the assays for which SNP genotypes were reported. Lessons from the survey are that special attention should be given to the quality of the DNA samples prior to genotyping, and that a conservative approach for calling the genotypes should be used to achieve a high accuracy.

  • What is the word for 'Engineering' in Swedish : Swedish students conceptions of their discipline
  • 2007
  • Rapport (övrigt vetenskapligt)abstract
    • Engineering education in Sweden – as in the rest of the world – is experiencing a decline in student interest. There are concerns about the ways in which students think about engineering education, why they join an academic programme in engineering, and why they persist in their studies. In this context the aims of the Nationellt ämnesdidaktiskt Centrum för Teknikutbildning i Studenternas Sammanhang project (CeTUSS) is to investigate the student experience and to identify and support a continuing network of interested researchers, as well as in building capacity for disciplinary pedagogic investigation.The Stepping Stones project brings together these interests in a multi-researcher, multi-institutional study that investigates how tudents and academic staff perceive engineering in Sweden and in Swedish education. The first results of that project are reported here. As this study is situated uniquely in Swedish education, it allows for exploration of “a Swedish perspective” on conceptions of engineering. The Stepping Stones project was based on a model of research capacity-building previously instantiated in the USA and Australia (Fincher & Tenenberg, 2006).

  • Treatment modelling : the influence of micro-environmental conditions.
  • 2008
  • Ingår i: Acta Oncol. - 1651-226X. ; 47:5, s. 896-905
  • Tidskriftsartikel (övrigt vetenskapligt)abstract
    • The interest in theoretical modelling of radiation response has grown steadily from a fast method to estimate the gain of new treatment strategies to an individualisation tool that may be used as part of the treatment planning algorithms. While the advantages of biological optimisation of plans are obvious, accurate theoretical models and realistic information about the micro-environmental conditions in tissues are needed. This paper aimed to investigate the clinical implications of taking into consideration the details of the tumour microenvironmental conditions. The focus was on the availability of oxygen and other nutrients to tumour cells and the relationship between cellular energy reserves and DNA repair ability as this is thought to influence the response of the various hypoxic cells. The choice of the theoretical models for predicting the response (the linear quadratic model or the inducible repair model) was also addressed. The modelling performed in this project has shown that the postulated radiobiological differences between acute and chronic hypoxia have some important clinical implications which may help to understand the mechanism behind the current success rates of radiotherapy. The results also suggested that it is important to distinguish between the two types of hypoxia in predictive assays and other treatment simulations.

  • Vascular oxygen content and the tissue oxygenation--a theoretical analysis.
  • 2008
  • Ingår i: Med Phys. - 0094-2405. ; 35:2, s. 539-45
  • Tidskriftsartikel (övrigt vetenskapligt)abstract
    • Several methods exist for evaluating tumor oxygenation as hypoxia is an important prognostic factor for cancer patients. They use different measuring principles that highlight various aspects of oxygenation. The results could be empirically correlated, but it has been suspected that there could be discordances in some cases. This study describes an analysis of the relationship between vascular and tissue oxygenations. Theoretical simulation has been employed to characterize tissue oxygenations for a broad range of distributions of intervessel distances and vascular oxygenations. The results were evaluated with respect to the implications for practical measurements of tissue oxygenations. The findings showed that although the tissue oxygenation is deterministically related to vascular oxygenation, the relationship between them is not unequivocal. Variability also exists between the fractions of values below the sensitivity thresholds of various measurement methods which in turn could be reflected in the power of correlations between results from different methods or in the selection of patients for prognostic studies. The study has also identified potential difficulties that may be encountered at the quantitative evaluation of the results from oxygenation measurements. These could improve the understanding of oxygenation measurements and the interpretation of comparisons between results from various measurement methods.

  • Thalidomide and dexamethasone vs. bortezomib and dexamethasone for melphalan refractory myeloma: a randomized study.
  • 2012
  • Ingår i: European journal of haematology. - 0902-4441. ; 88:6, s. 485-496
  • Tidskriftsartikel (övrigt vetenskapligt)abstract
    • Objectives: Thalidomide and bortezomib have been frequently used for second-line therapy in patients with myeloma relapsing after or refractory to initial melphalan-based treatment, but no randomized trials have been published comparing these two treatment alternatives.Methods: Thalidomide- and bortezomib-naive patients with melphalan refractory myeloma were randomly assigned to low-dose thalidomide + dexamethasone (Thal-Dex) or bortezomib + dexamethasone (Bort-Dex). At progression on either therapy, the patients were offered crossover to the alternative drug combination. An estimated 300 patients would be needed for the trial to detect a 50% difference in median PFS between the treatment arms.Results: After inclusion of 131 patients, the trial was prematurely closed because of low accrual. Sixty-seven patients were randomized to Thal-Dex and 64 to Bort-Dex. Progression-free survival was similar (median, 9.0 months for Thal-Dex and 7.2 for Bort-Dex). Response rate was similar (55% for Thal-Dex and 63% for Bort-Dex), but time to response was shorter (P < 0.05) and the VGPR rate higher (P < 0.01) for Bort-Dex. Time-to-other treatment after crossover was similar (median, 13.2 months for Thal-Dex and 11.2 months for Bort-Dex), as was overall survival (22.8 months for Thal-Dex and 19.0 for Bort-Dex). Venous thromboembolism was seen in seven patients and cerebrovascular events in four patients in the Thal-Dex group. Severe neuropathy, reactivation of herpes virus infections, and mental depression were more frequently observed in the Bort-Dex group. In the quality-of-life analysis, no difference was noted for physical function, pain, and global quality of life. Fatigue and sleep disturbances were significantly more prevalent in the Bort-Dex group.Conclusions: Thalidomide (50-100 mg daily) in combination with dexamethasone seems to have an efficacy comparable with that of bortezomib and dexamethasone in melphalan refractory myeloma. However, the statistical strength of the results in this study is limited by the low number of included patients.
