  • A conceptual framework for curriculum design in physiotherapy education: an internationaöl perspective
  • 2003
  • Ingår i: Advances in Physiotherapy. ; 5:4, s. 161-8
  • Tidskriftsartikel (refereegranskat)abstract
    • Globalization is having a significant impact on healthcare and physiotherapy education, among other sectors, can benefit from this trend. The main aim of this work was to develop and describe a conceptual framework for physiotherapy curriculum design and, in doing so, to stimulate international debate on physiotherapy education. The framework was developed through an international collaboration and was tried out in the participating schools in order to refine it further. The current framework consists of three elements to be taken into account in physiotherapy curriculum design: (1) The content aspect or the knowledge base of physiotherapy; (2) the learning aspect or the student's learning process; and (3) the socio-cultural context aspect, which concerns the way in which physiotherapy is experienced and practised. The content aspect includes a description of core concepts of physiotherapy: body, movement and interaction, and acknowledges that physiotherapy should be science-based. The learning aspect and the socio-cultural context aspect form separate parts of the framework. Nonetheless, all aspects are intertwined and reflect theory-practice integration. This framework is offered for critical reflection and as the basis for a debate on the development and evaluation of physiotherapy programmes. Further work is needed in testing the relevance of this framework for curriculum design in different countries and settings. Keywords: Core knowledge; curriculum development; physiotherapy practice; professional issues; post-graduate education; socio-cultural context; student's learning; theory-practice integration; undergraduate education

  • What were you thinking? A methodological approach for exploring decision-making and learning in physical education
  • 2019
  • Ingår i: Sport, Education and Society. - : Routledge. - 1357-3322 .- 1470-1243. ; 24:8, s. 828-840
  • Tidskriftsartikel (refereegranskat)abstract
    • The broad purpose of this paper is to consider the relationship betweendecision-making and learning. Specifically, our aim is to propose amethodology that provides a theoretical framing along with proceduresfor investigating this relationship in Physical Education (PE). By utilizingselected parts of John Dewey’s educational theories, the paper presentsa theoretical exposition of decision-making as an individual processcontaining both ‘practical’ and ‘cognitive’ aspects. By combining thistheoretical conceptualization with a description of concrete researchmethods, the paper proposes a methodological approach enablingresearchers to get empirically closer to the phenomenon of individualdecision-making within PE learning. We argue that by doing so,researchers in the field of PE can study certain aspects of learning notexplicitly emphasized within existing methodological approaches.

  • Nordic adolescents responding to demanding survey scales in boring contexts: Examining straightlining
  • 2022
  • Ingår i: Journal of Adolescence. - : Wiley. - 0140-1971 .- 1095-9254. ; 94:6, s. 829 - 843
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: Straightlining, or identical responses across all items within a multi-item scale, is often taken as an indication that responses to all items in a questionnaire are of poor quality. The purpose of this study was to examine straightlining on two scales: The Sense of Unity Scale (SUS) and the short version of the Warwick-Edinburgh Mental Well-being Scale (SWEMWBS). Methods: Data stem from the 2017–2018 data collections in four Nordic countries of the Health Behaviour in School-children study (HBSC) (15-year-old students only; 50.9% girls; n = 5928). Data were weighted to adjust for oversampling of Swedish-speaking Finnish students and to equalize sample size across countries. The main analyses were done with general linear modeling with adjustments for cluster effects (school classes). Results: The proportion with straightlining on SUS was 22.8%, varying from 5.8% among Swedish girls to 46.4% among Finnish boys. The proportion with straightlining on SWEMWBS was 18.4%, varying from 5.2% among Norwegian girls to 46.0% among Finnish boys. Straightlining on one of the scales correlated with straightlining on the other one. Straightlining tended to inflate Cronbach's α values and reduce number of factors in factor analyses. Associations between the two scales and external variables tended to be lower among straightlining students. Associations between external variables (other than SUS/SWEMWBS) are on average slightly weaker among straightliners. Straightlining students obtained more favorable scores on several resource-related variables. Conclusion: Although some problems have been identified, straightlining does not serve well as a general indicator of poor data quality.

  • Salmonid stocking in five North Atlantic jurisdictions: Identifying drivers and barriers to policy change
  • 2018
  • Ingår i: Aquatic Conservation-Marine and Freshwater Ecosystems. - : Wiley. - 1052-7613. ; 28:6, s. 1451-1464
  • Tidskriftsartikel (refereegranskat)abstract
    • New knowledge challenges long-established practices of fish stocking and transfer because of increasing scientific consensus that the release of cultivated fish can pose risks to biodiversity; however, stocking can also improve fisheries, creating difficult decision trade-offs regarding its use. Accordingly, controversy persists about fish stocking and transfer. No studies, however, have embraced a multinational perspective to understand the important governance dimensions of the success and failure of salmonid stocking and transfer policies. The present study has analysed the historical development and contemporary governance of the stocking and transfer of native and non-native salmonids of the genera Salmo, Salvelinus, and Oncorhynchus in five legislative units around the North Atlantic Ocean: the Atlantic Provinces of Canada, France, Germany, Norway, and Sweden. The study is based on the analyses of published and unpublished literature, and a survey of experts. Current salmonid stocking policies and practices varied significantly among jurisdictions; the degree of policy change varied, from radical and rapid changes de jure and de facto in Atlantic Canada and Norway to incremental mostly de jure changes in France and Germany. Rapid policy change in Atlantic Canada, Norway, and partly in Sweden can be explained by the socio-political importance of salmonid fisheries, stocking regulations based on policy objectives to conserve wild Atlantic salmon (Salmo salar), well-documented examples of the harmful consequences of transfers of non-native species, and well-developed vertical governance linkages. The policy changes resemble that of the 'punctuated equilibrium policy framework'. By contrast, France and Germany place less socio-political emphasis on salmonids, have stocking regulations less directed at wild salmonids, more local-level decision making, more species-rich fish communities, and little evidence of adverse ecological impacts of the transfer and stocking of salmonids. This has led to small, incremental changes in stocking policy de facto that are reflective of the 'advocacy coalition policy framework'.

  • Lessons learnt from the first EMEP intensive measurement periods
  • 2012
  • Ingår i: Atmospheric Chemistry and Physics. - : Copernicus GmbH. - 1680-7316 .- 1680-7324. ; 12:17, s. 8073-8094
  • Tidskriftsartikel (refereegranskat)abstract
    • The first EMEP intensive measurement periods were held in June 2006 and January 2007. The measurements aimed to characterize the aerosol chemical compositions, including the gas/aerosol partitioning of inorganic compounds. The measurement program during these periods included daily or hourly measurements of the secondary inorganic components, with additional measurements of elemental- and organic carbon (EC and OC) and mineral dust in PM1, PM2.5 and PM10. These measurements have provided extended knowledge regarding the composition of particulate matter and the temporal and spatial variability of PM, as well as an extended database for the assessment of chemical transport models. This paper summarise the first experiences of making use of measurements from the first EMEP intensive measurement periods along with EMEP model results from the updated model version to characterise aerosol composition. We investigated how the PM chemical composition varies between the summer and the winter month and geographically. The observation and model data are in general agreement regarding the main features of PM10 and PM2.5 composition and the relative contribution of different components, though the EMEP model tends to give slightly lower estimates of PM10 and PM2.5 compared to measurements. The intensive measurement data has identified areas where improvements are needed. Hourly concurrent measurements of gaseous and particulate components for the first time facilitated testing of modelled diurnal variability of the gas/aerosol partitioning of nitrogen species. In general, the modelled diurnal cycles of nitrate and ammonium aerosols are in fair agreement with the measurements, but the diurnal variability of ammonia is not well captured. The largest differences between model and observations of aerosol mass are seen in Italy during winter, which to a large extent may be explained by an underestimation of residential wood burning sources. It should be noted that both primary and secondary OC has been included in the calculations for the first time, showing promising results. Mineral dust is important, especially in southern Europe, and the model seems to capture the dust episodes well. The lack of measurements of mineral dust hampers the possibility for model evaluation for this highly uncertain PM component. There are also lessons learnt regarding improved measurements for future intensive periods. There is a need for increased comparability between the measurements at different sites. For the nitrogen compounds it is clear that more measurements using artefact free methods based on continuous measurement methods and/or denuders are needed. For EC/OC, a reference methodology (both in field and laboratory) was lacking during these periods giving problems with comparability, though measurement protocols have recently been established and these should be followed by the Parties to the EMEP Protocol. For measurements with no defined protocols, it might be a good solution to use centralised laboratories to ensure comparability across the network. To cope with the introduction of these new measurements, new reporting guidelines have been developed to ensure that all proper information about the methodologies and data quality is given.

  • Cost and health outcome of primary percutaneous coronary intervention versus thrombolysis in acute ST-segment elevation myocardial infarction-Results of the Swedish Early Decision reperfusion Study (SWEDES) trial.
  • 2010
  • Ingår i: American heart journal. - : Elsevier BV. - 1097-6744 .- 0002-8703. ; 160:2, s. 322-8
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: In ST-elevation myocardial infarction, primary percutaneous coronary intervention (PCI) has a superior clinical outcome, but it may increase costs in comparison to thrombolysis. The aim of the study was to compare costs, clinical outcome, and quality-adjusted survival between primary PCI and thrombolysis. METHODS: Patients with ST-elevation myocardial infarction were randomized to primary PCI with adjunctive enoxaparin and abciximab (n = 101), or to enoxaparin followed by reteplase (n = 104). Data on the use of health care resources, work loss, and health-related quality of life were collected during a 1-year period. Cost-effectiveness was determined by comparing costs and quality-adjusted survival. The joint distribution of incremental costs and quality-adjusted survival was analyzed using a nonparametric bootstrap approach. RESULTS: Clinical outcome did not differ significantly between the groups. Compared with the group treated with thrombolysis, the cost of interventions was higher in the PCI-treated group ($4,602 vs $3,807; P = .047), as well as the cost of drugs ($1,309 vs $1,202; P = .001), whereas the cost of hospitalization was lower ($7,344 vs $9,278; P = .025). The cost of investigations, outpatient care, and loss of production did not differ significantly between the 2 treatment arms. Total cost and quality-adjusted survival were $25,315 and 0.759 vs $27,819 and 0.728 (both not significant) for the primary PCI and thrombolysis groups, respectively. Based on the 1-year follow-up, bootstrap analysis revealed that in 80%, 88%, and 89% of the replications, the cost per health outcome gained for PCI will be <$0, $50,000, and $100,000 respectively. CONCLUSION: In a 1-year perspective, there was a tendency toward lower costs and better health outcome after primary PCI, resulting in costs for PCI in comparison to thrombolysis that will be below the conventional threshold for cost-effectiveness in 88% of bootstrap replications.

  • Risk Reduction for Cardiac Events After Primary Coronary Intervention Compared With Thrombolysis for Acute ST-Elevation Myocardial Infarction (Five-Year Results of the Swedish Early Decision Reperfusion Strategy [SWEDES] Trial).
  • 2010
  • Ingår i: The American journal of cardiology. - : Elsevier BV. - 1879-1913 .- 0002-9149. ; 106:12, s. 1685-91
  • Tidskriftsartikel (refereegranskat)abstract
    • Primary percutaneous coronary intervention (PPCI) for ST-elevation myocardial infarction compares favorably to thrombolysis. In previous studies the benefit has been restricted to the early postinfarction period with no additional risk decrease beyond this period. Long-term outcome after use of third-generation thrombolytics and modern adjunctive pharmaceutics in the 2 treatment arms has not been investigated. This study was conducted to compare 5-year outcome after updated regimens of PPCI or thrombolysis. Patients with ST-elevation myocardial infarction were randomized to enoxaparin and abciximab followed by PPCI (n = 101) or enoxaparin followed by reteplase (n = 104), with prehospital initiation of therapy in 42% of patients. Data on survival and major cardiac events were obtained from Swedish national registries after 5.3 years. PPCI resulted in a better outcome with respect to the composite of death or recurrent myocardial infarction (hazard ratio 0.54, confidence interval 0.31 to 0.95) compared to thrombolysis. This was attributed to a significant decrease in cardiac deaths (hazard ratio 0.16, confidence interval 0.04 to 0.74). The difference evolved continuously over the 5-year follow-up. After adjustment for covariates, a significant benefit remained with respect to cardiac death or recurrent infarction but not for the composite of total survival or recurrent myocardial infarction (p = 0.07). The observed differences were not seen in patients in whom therapy was initiated in the prehospital phase. In conclusion, PPCI in combination with enoxaparin and abciximab compares favorably to thrombolysis in combination with enoxaparin with a risk decrease that stretches beyond the early postinfarction period. Prehospital thrombolysis may, however, match PPCI in long-term outcome.

  • Temporal changes in TIMI myocardial perfusion grade in relation to epicardial flow, ST-resolution and left ventricular function after primary percutaneous coronary intervention
  • 2007
  • Ingår i: Coron Artery Dis. - 0954-6928. ; 18:7, s. 513-518
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Myocardial perfusion at the end of reperfusion therapy assessed angiographically with thrombolysis in myocardial infarction (TIMI) myocardial perfusion grade (TMPG) has been associated with recovery of left ventricular (LV) function and survival. The aim of this analysis was to study the evolution of TMPG within the first week following primary percutaneous coronary intervention (PCI) and its association with ECG-derived ST-segment resolution (STRES) and recovery of LV function. METHODS: A total of 76 patients with acute myocardial infarction were pretreated with enoxaparine and abciximab and subjected to primary PCI within a prospective study and evaluated with TMPG assessed on coronary angiography at the end of the procedure and after 5-7 days. STRES was evaluated at 120 min post inclusion and global LV function was assessed by echocardiography after 30 days. RESULTS: Reperfusion (TIMI flow 2-3) was reached in all patients. Forty one percent had 'open myocardium' (i.e. TMPG 2 or 3) after PCI, a number that increased to 61% after 5-7 days (P=0.003). STRES >50% was reached in 73% of the patients and there was a good correlation between TMPG and STRES. Furthermore, those who improved from 'closed' to 'open myocardium' had higher STRES (and similar to those with 'open myocardium' already post-PCI) than those who had 'closed myocardium' at both occasions (80 vs. 52%, P=0.012). CONCLUSION: A significant increase was found in the number of patients with 'open myocardium' within the first week post-primary PCI and STRES seems to predict this improvement.
