    Time management skills in relation to general self-efficacy and parental sense of competence in individuals with and without cognitive disabilities2019In: Cogent Psychology, E-ISSN 2331-1908, Vol. 6, no 1, article id 1655981Article in journal (Refereed)
    Abstract [en]

    Purpose: The aim of the study was to investigate to what extent time management skills are associated with general self-efficacy and parental sense of competence, and if there are any differences between individuals with and without cognitive disabilities in these aspects.

    Material and Methods: The study had a comparative cross-sectional design. Totally 86 individuals with cognitive disabilities (of whom 31 were parents), and 154 without disabilities (of whom 68 were parents) were included (N = 240). The Swedish versions of the Assessment of Time Management Skills (including time management, organisation & planning, and regulation of emotion subscales), General Self-Efficacy, and Parental Sense of Competence scale (including satisfaction, efficacy, and interest subscales) were used to collect data.

    Results: There were significant differences (p < .001) between individuals with and without cognitive disabilities in all three subscales of Assessment of Time Management Skills and in General Self-Efficacy. Overall, individuals with a cognitive disability scored lower than persons without cognitive disabilities. A significant difference was observed between parents in all three subscales of time management skills after controlling for age and education (p < .0005). Parents with cognitive disabilities, compared to parents without cognitive disability, scored significantly lower in all measured scales, except for the interest subscale. In parents with a cognitive disability, there was a significant correlation between all three subscales of Time Management Skills and satisfaction. Among parents without a cognitive disability there was a significant correlation between time management; and organisation & planning subscales; and efficacy, and between General Self-Efficacy and time management.

    Conclusions: Poor time management, planning and organisational skills, as well as a deficit in regulation of emotions may have a negative impact on general self-efficacy and parental sense of competence.

    Resource Sharing among Prioritized Real-Time Applications on Multiprocessors2015In: ACM SIGBED Review - Special Issue on the 6th International Workshop on Compositional Theory and Technology for Real-Time Embedded Systems Homepage archiveVolume 12 Issue 1, 2015, p. 46-55Conference paper (Refereed)
    Abstract [en]

    In this paper, we propose a new protocol for handling resource sharing among prioritized real-time applications composed on a multiprocessor platform. We propose an optimal priority assignment algorithm which assigns unique priorities to the applications based on information in their interfaces. We have performed experimental evaluations to compare the proposed protocol (called MSOS-Priority) to the current state of the art locking protocols under multiprocessor partitioned scheduling, i.e., MPCP, MSRP, FMLP, MSOS, and OMLP. The valuations show that MSOS-Priority mostly performs significantly better than alternative approaches.

    Resource Sharing under Multiprocessor Semi-Partitioned Scheduling2012In: 2012 IEEE International Conference on Embedded and Real-Time Computing Systems and Applications: Proceedings, IEEE, 2012, p. 290-299Conference paper (Refereed)
    Abstract [en]

    Semi-partitioned scheduling has become the subject of recent interest for multiprocessors due to better utilization results, compared to conventional global and partitioned scheduling algorithms. Under semi-partitioned scheduling, a major group of tasks are assigned to fixed processors while a low number of tasks are allocated to more than one processor. Various task assigning techniques have recently been proposed in a semi-partitioned environment. However, a synchronization mechanism for resource sharing among tasks in semi-partitioned scheduling has not yet been investigated. In this paper we propose and evaluate two methods for handling resource sharing under semi-partitioned scheduling in multiprocessor platforms. The main challenge addressed in this paper is to serve the resource requests of tasks that are assigned to different processors.

    Towards Resource Sharing under Multiprocessor Semi-Partitioned Scheduling2012In: 7th IEEE International Symposium on Industrial Embedded Systems (SIES'12): Conference Proceedings, IEEE, 2012, p. 315-318Conference paper (Refereed)
    Abstract [en]

    Semi-partitioned scheduling has been the subject of recent interest, compared with conventional global and partitioned scheduling algorithms for multiprocessors, due to better utilization results. In semi-partitioned scheduling most tasks are assigned to fixed processors while a low number of tasks are split up and allocated to different processors. Various techniques have recently been proposed to assign tasks in a semi-partitioned environment. However, an appropriate resource sharing mechanism for handling the resource requests between tasks in semi-partitioned scheduling has not yet been investigated. In this paper we propose two methods for handling resource sharing under semi-partitioned scheduling in multiprocessor platforms. The main challenge is to handle the resource requests of tasks that are split over multiple processors.

    Guaranteed Success?: The Effects of Export Credit Guarantees on Firm Performance2019Conference paper (Refereed)
    Abstract [en]

    Many countries offer government-backed export credit guarantees to domestic firms. We investigate the effects of such guarantees on firm exports, jobs and value added. Using uniquely detailed and exhaustive transaction-level panel data on guarantees and granular information on trade, exporters and foreign buyers, we perform difference-indifferences matching estimations. We find that guarantees improve firm performance. However, the effects are strikingly heterogeneous across firm size and response variables. Using guarantees increases the firm-destination probability of exporting and the value of exports by 18 and 172 percent, respectively, but does not generally increase jobs or value added. Smaller firms benefit the most in terms of exports. Overall, the evidence suggests a causal link from guarantees to firm export performance.

    Tillgänglighet för rullstolsburna: Politik, praktik och vardagsliv. En fallstudie i Örebro2007Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna uppsats är att studera hur man i Örebro arbetar med den fysiska tillgängligheten i staden, och vilka erfarenheter detta arbete har gett. Jag utgår från tre frågor. Hur arbetar man politiskt när det gäller tillgänglighet i Örebro? Hur planerar man praktiskt inom Örebro kommun med frågor kring tillgänglighet i staden? Hur ser rullstolsburna på tillgängligheten i Örebro? För att besvara frågorna studerar jag litteratur och gällande lagar som behandlar ämnet tillgänglighet på olika sätt. Jag genomför även tre intervjuer som jag spelar in med en politiker, en tjänsteman samt en person som är rullstolsburen. Dessa inspelade intervjuer skriver jag rent för att kunna analysera i uppsatsen.

    Utifrån min analys och den litteratur jag studerat kommer jag till slut fram till att det i planeringen av Örebro finns ett samarbete mellan politiker, tjänstemän samt handikapporganisationer. Politiskt arbetas det med att ge direktiv till tjänstemän. Praktiskt handlar det om att tillämpa gällande lagstiftning samt genom praktiska demonstrationer visa hur verkligheten ser ut för handikappade. Rullstolsburna ser tillgänglighet som något som sakta men säkert blir bättre, även om det finns mycket som kan förbättras.

    On Practising in Physical Education: Outline for a pedagogical model2018In: Physical Education and Sport Pedagogy, ISSN 1740-8989, E-ISSN 1742-5786, Vol. 23, no 2, p. 197-208Article in journal (Refereed)
    Abstract [en]

    Background: Models-based approaches to physical education have inrecent years developed as a way for teachers and students toconcentrate on a manageable number of learning objectives, and alignpedagogical approaches with learning subject matter and context. Thispaper draws on Hannah Arendt’s account of vita activa to map existingapproaches to physical education as oriented towards: (a) health andexercise, (b) sport and games, and (c) experience and exploration.Purpose: The aim of the paper is to outline a new pedagogical model forphysical education: a practising model. We argue that the form of humanactivity related to practising is not well represented in existingorientations and models. To sustain this argument, we highlight themost central aspects of practising, and at the same time describe centralfeatures of the model.Relevance and implications: The paper addresses pedagogicalimplications the practising model has for physical education teachers.Central learning outcomes and teaching strategies related to fouressential and ‘non-negotiable’ features of the practising model arediscussed. These strategies are: (1) acknowledging subjectivity andproviding meaningful challenges, (2) focusing on content and the aimsof practising, (3) specifying and negotiating standards of excellence and(4) providing adequate time to practising.Conclusion: The practising model has the potential to inform newperspectives on pedagogical approaches, and renew and improveworking methods and learning practices, in physical education.

    Byggföretagens hantering av fuktsäkerhetsprojektering – med fokus på projektörer2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Moisture damage usually occurs due to incorrect planning, design and execution throughout the construction process. These inaccuracies result in large cost of action that can be minimized or even eliminated if the moisture safety work is done properly. The design phase is an important stage and a properly implemented moisture safety design can be of great importance for the moisture safety work during the construction process. The planners’ role at this stage is to carry out a moisture safety work based on the requirements of the developer. The purpose of this exam is to find out the choice of method made by the planners’ in the implementation of moisture safety design and to review the need of competence development among the planners’ about moisture.    The two methods that have been used to achieve the purpose of this exam are interviews and literature studies. The target group in this exam is the construction companies in Sweden. The way of how the companies handle of moisture safety design is being reviewed in the design stage.  Of all involved actors in the design phase, the focus is on the planners'. Three out of five planners' are dissatisfied with their own moisture competence, which is in line with the opinion of the experts' of moisture about the planners' competence.   During the interviews, several experts' of moisture have pointed out the need for increased moisture competence among the planners'. The lack competence means that the planners' cannot consider or detect possible moisture risks during the moisture safety design. The method that is used by 80% of the planners' during moisture safety design is the ByggaF method. The planners' knowledge of ByggaF is still low according to the experts' of moisture and for this reason the planners' cannot apply entirely the ByggaF method. The tools that planners' need to have with them is knowledge and experience. In order to discover what is wrong, you need to have both the knowledge and experience about what is right.  Based on the response from both the building committee and the participants, a review of the documentation regarding the moisture safety work is not always requested by the building committee.  The conclusion is that projectors must acquire competence in both moisture and the ByggaF method.

    Dissociable relations between amygdala subregional networks and psychopathy trait dimensions in conduct-disordered juvenile offenders2016In: Human Brain Mapping, ISSN 1065-9471, E-ISSN 1097-0193, Vol. 37, no 11, p. 4017-4033Article in journal (Refereed)
    Abstract [en]

    Psychopathy is a serious psychiatric phenomenon characterized by a pathological constellation of affective (e.g., callous, unemotional), interpersonal (e.g., manipulative, egocentric), and behavioral (e.g., impulsive, irresponsible) personality traits. Though amygdala subregional defects are suggested in psychopathy, the functionality and connectivity of different amygdala subnuclei is typically disregarded in neurocircuit-level analyses of psychopathic personality. Hence, little is known of how amygdala subregional networks may contribute to psychopathy and its underlying trait assemblies in severely antisocial people. We addressed this important issue by uniquely examining the intrinsic functional connectivity of basolateral (BLA) and centromedial (CMA) amygdala networks in relation to affective, interpersonal, and behavioral traits of psychopathy, in conduct-disordered juveniles with a history of serious delinquency (N = 50, mean age = 16.83 ± 1.32). As predicted, amygdalar connectivity profiles exhibited dissociable relations with different traits of psychopathy. Interpersonal psychopathic traits not only related to increased connectivity of BLA and CMA with a corticostriatal network formation accommodating reward processing, but also predicted stronger CMA connectivity with a network of cortical midline structures supporting sociocognitive processes. In contrast, affective psychopathic traits related to diminished CMA connectivity with a frontolimbic network serving salience processing and affective responding. Finally, behavioral psychopathic traits related to heightened BLA connectivity with a frontoparietal cluster implicated in regulatory executive functioning. We suggest that these trait-specific shifts in amygdalar connectivity could be particularly relevant to the psychopathic phenotype, as they may fuel a self-centered, emotionally cold, and behaviorally disinhibited profile.

    Motion sensor-based assessment of Parkinson's disease motor symptoms during leg agility tests: results from levodopa challenge2019In: IEEE journal of biomedical and health informatics, ISSN 2168-2194, E-ISSN 2168-2208Article in journal (Refereed)
    Abstract [en]

    Parkinson's disease (PD) is a degenerative, progressive disorder of the central nervous system that mainly affects motor control. The aim of this study was to develop data-driven methods and test their clinimetric properties to detect and quantify PD motor states using motion sensor data from leg agility tests. Nineteen PD patients were recruited in a levodopa single dose challenge study. PD patients performed leg agility tasks while wearing motion sensors on their lower extremities. Clinical evaluation of video recordings was performed by three movement disorder specialists who used four items from the motor section of the Unified PD Rating Scale (UPDRS), the treatment response scale (TRS) and a dyskinesia score. Using the sensor data, spatiotemporal features were calculated and relevant features were selected by feature selection. Machine learning methods like support vector machines (SVM), decision trees and linear regression, using 10-fold cross validation were trained to predict motor states of the patients. SVM showed the best convergence validity with correlation coefficients of 0.81 to TRS, 0.83 to UPDRS #31 (body bradykinesia and hypokinesia), 0.78 to SUMUPDRS (the sum of the UPDRS items: #26-leg agility, #27-arising from chair and #29-gait), and 0.67 to dyskinesia. Additionally, the SVM-based scores had similar test-retest reliability in relation to clinical ratings. The SVM-based scores were less responsive to treatment effects than the clinical scores, particularly with regards to dyskinesia. In conclusion, the results from this study indicate that using motion sensors during leg agility tests may lead to valid and reliable objective measures of PD motor symptoms.

    Objective assessment of Parkinson’s disease motor symptoms during leg agility test using motion sensors2018Conference paper (Refereed)
    Abstract [en]

    Title: Objective assessment of Parkinson’s disease motor symptoms during leg agility test using motion sensors

    Objective: To develop and evaluate machine learning methods for assessment of Parkinson’s disease (PD) motor symptoms using leg agility (LA) data collected with motion sensors during a single dose experiment.

    Background: Nineteen advanced PD patients (Gender: 14 males and 5 females, mean age: 71.4, mean years with PD: 9.7, mean years with levodopa: 9.5) were recruited in a single center, open label, single dose clinical trial in Sweden [1].

    Methods: The patients performed up to 15 LA tasks while wearing motions sensors on their foot ankle. They performed tests at pre-defined time points starting from baseline, at the time they received a morning dose (150% of their levodopa equivalent morning dose), and at follow-up time points until the medication wore off. The patients were video recorded while performing the motor tasks. and three movement disorder experts rated the observed motor symptoms using 4 items from the Unified PD Rating Scale (UPDRS) motor section including UPDRS #26 (leg agility), UPDRS #27 (Arising from chair), UPDRS #29 (Gait), UPDRS #31 (Body Bradykinesia and Hypokinesia), and dyskinesia scale. In addition, they rated the overall mobility of the patients using Treatment Response Scale (TRS), ranging from -3 (very off) to 3 (very dyskinetic). Sensors data were processed and their quantitative measures were used to develop machine learning methods, which mapped them to the mean ratings of the three raters. The quality of measurements of the machine learning methods was assessed by convergence validity, test-retest reliability and sensitivity to treatment.

    Results: Results from the 10-fold cross validation showed good convergent validity of the machine learning methods (Support Vector Machines, SVM) with correlation coefficients of 0.81 for TRS, 0.78 for UPDRS #26, 0.69 for UPDRS #27, 0.78 for UPDRS #29, 0.83 for UPDRS #31, and 0.67 for dyskinesia scale (P<0.001). There were good correlations between scores produced by the methods during the first (baseline) and second tests with coefficients ranging from 0.58 to 0.96, indicating good test-retest reliability. The machine learning methods had lower sensitivity than mean clinical ratings (Figure. 1).

    Conclusions: The presented methodology was able to assess motor symptoms in PD well, comparable to movement disorder experts. The leg agility test did not reflect treatment related changes.

    Feasibility of a multi-sensor data fusion method for assessment of Parkinson’s disease motor symptoms2018Conference paper (Other academic)
    Abstract [en]

    Title: Feasibility of a multi-sensor data fusion method for assessment of Parkinson’s disease motor symptoms

    Objective: To assess the feasibility of measuring Parkinson’s disease (PD) motor symptoms with a multi-sensor data fusion method. More specifically, the aim is to assess validity, reliability and sensitivity to treatment of the methods.

    Background: Data from 19 advanced PD patients (Gender: 14 males and 5 females, mean age: 71.4, mean years with PD: 9.7, mean years with levodopa: 9.5) were collected in a single center, open label, single dose clinical trial in Sweden [1].

    Methods: The patients performed leg agility and 2-5 meter straight walking tests while wearing motion sensors on their limbs. They performed the tests at baseline, at the time they received the morning dose, and at pre-specified time points until the medication wore off. While performing the tests the patients were video recorded. The videos were observed by three movement disorder specialists who rated the symptoms using a treatment response scale (TRS), ranging from -3 (very off) to 3 (very dyskinetic). The sensor data consisted of lower limb data during leg agility, upper limb data during walking, and lower limb data during walking. Time series analysis was performed on the raw sensor data extracted from 17 patients to derive a set of quantitative measures, which were then used during machine learning to be mapped to mean ratings of the three raters on the TRS scale. Combinations of data were tested during the machine learning procedure.

    Results: Using data from both tests, the Support Vector Machines (SVM) could predict the motor states of the patients on the TRS scale with a good agreement in relation to the mean ratings of the three raters (correlation coefficient = 0.92, root mean square error = 0.42, p<0.001). Additionally, there was good test-retest reliability of the SVM scores during baseline and second tests with intraclass-correlation coefficient of 0.84. Sensitivity to treatment for SVM was good (Figure 1), indicating its ability to detect changes in motor symptoms. The upper limb data during walking was more informative than lower limb data during walking since SVMs had higher correlation coefficient to mean ratings.  

    Conclusions: The methodology demonstrates good validity, reliability, and sensitivity to treatment. This indicates that it could be useful for individualized optimization of treatments among PD patients, leading to an improvement in health-related quality of life.

    Verification of a Method for Measuring Parkinson’s Disease Related Temporal Irregularity in Spiral Drawings2017In: Sensors, ISSN 1424-8220, E-ISSN 1424-8220, Vol. 17, no 10, article id 2341Article in journal (Refereed)
    Abstract [en]

    Parkinson’s disease (PD) is a progressive movement disorder caused by the death of dopamine-producing cells in the midbrain. There is a need for frequent symptom assessment, since the treatment needs to be individualized as the disease progresses. The aim of this paper was to verify and further investigate the clinimetric properties of an entropy-based method for measuring PD-related upper limb temporal irregularities during spiral drawing tasks. More specifically, properties of a temporal irregularity score (TIS) for patients at different stages of PD, and medication time points were investigated. Nineteen PD patients and 22 healthy controls performed repeated spiral drawing tasks on a smartphone. Patients performed the tests before a single levodopa dose and at specific time intervals after the dose was given. Three movement disorder specialists rated videos of the patients based on the unified PD rating scale (UPDRS) and the Dyskinesia scale. Differences in mean TIS between the groups of patients and healthy subjects were assessed. Test-retest reliability of the TIS was measured. The ability of TIS to detect changes from baseline (before medication) to later time points was investigated. Correlations between TIS and clinical rating scores were assessed. The mean TIS was significantly different between healthy subjects and patients in advanced groups (p-value = 0.02). Test-retest reliability of TIS was good with Intra-class Correlation Coefficient of 0.81. When assessing changes in relation to treatment, TIS contained some information to capture changes from Off to On and wearing off effects. However, the correlations between TIS and clinical scores (UPDRS and Dyskinesia) were weak. TIS was able to differentiate spiral drawings drawn by patients in an advanced stage from those drawn by healthy subjects, and TIS had good test-retest reliability. TIS was somewhat responsive to single-dose levodopa treatment. Since TIS is an upper limb high-frequency-based measure, it cannot be detected during clinical assessment.

    Measuring temporal irregularity in spiral drawings of patients with Parkinson’s disease2017In: Abstracts of the 21st International Congress of Parkinson's Disease and Movement Disorders, John Wiley & Sons, 2017, Vol. 32, p. s252-s252, article id 654Conference paper (Other (popular science, discussion, etc.))
    Abstract [en]

    Objective: The aim of this work is to evaluate clinimetric properties of a method for measuring Parkinson’s disease (PD) upper limb temporal irregularities during spiral drawing tasks.

    Background: Basal ganglia fluctuations of PD patients are associated with motor symptoms and relating them to objective sensor-based measures may facilitate the assessment of temporal irregularities, which could be difficult to be assessed visually. The present study investigated the upper limb temporal irregularity of patients at different stages of PD and medication time points.

    Methods: Nineteen PD patients and 22 healthy controls performed repeated spiral drawing tasks on a smartphone. Patients performed the tests before a single levodopa dose and at specific time intervals after the dose was given. Three movement disorder specialists rated the videos of patients' performance according to six items of UPDRS-III, dyskinesia (Dys), and Treatment Response Scale (TRS). A temporal irregularity score (TIS) was developed using approximate entropy (ApEn) method. Differences in mean TIS between two groups of patients and healthy subjects, and also across four subject groups: early, intermediate, advanced patients and, healthy subjects were assessed. The relative ability of TIS to detect changes from baseline (no medication) to later time points when patients were on medication was assessed. Correlations between TIS and clinical rating scales were assessed by Pearson correlation coefficients and test-retest reliability of TIS was measured by intra-class correlation coefficients (ICC).

    Results: The mean TIS was significantly different between healthy subjects and patients (P<0.0001). When assessing the changes in relation to treatment, clinical-based scores (TRS and Dys) had better responsiveness than TIS. However, the TIS was able to capture changes from Off to On, and the wearing off effects. Correlations between TIS and clinical scales were low indicating poor validity. Test-retest reliability correlation coefficient of the mean TIS was good (ICC=0.67).

    Conclusions: Our study found that TIS was able to differentiate spiral drawings drawn by patients from those drawn by healthy subjects. In addition, TIS could capture changes throughout the levodopa cycle.TIS was weakly correlated to clinical ratings indicating that TIS measures high frequency upper limb temporal irregularities that could be difficult to be detected during clinical observations.

    A smartphone-based system to quantify dexterity in Parkinson's disease patients2017In: Informatics in Medicine Unlocked, ISSN 2352-9148, Vol. 9, p. 11-17Article in journal (Refereed)
    Abstract [en]

    Objectives

    The aim of this paper is to investigate whether a smartphone-based system can be used to quantify dexterity in Parkinson's disease (PD). More specifically, the aim was to develop data-driven methods to quantify and characterize dexterity in PD.

    Methods

    Nineteen advanced PD patients and 22 healthy controls participated in a clinical trial in Uppsala, Sweden. The subjects were asked to perform tapping and spiral drawing tests using a smartphone. Patients performed the tests before, and at pre-specified time points after they received 150% of their usual levodopa morning dose. Patients were video recorded and their motor symptoms were assessed by three movement disorder specialists using three Unified PD Rating Scale (UPDRS) motor items from part III, the dyskinesia scoring and the treatment response scale (TRS). The raw tapping and spiral data were processed and analyzed with time series analysis techniques to extract 37 spatiotemporal features. For each of the five scales, separate machine learning models were built and tested by using principal components of the features as predictors and mean ratings of the three specialists as target variables.

    Results

    There were weak to moderate correlations between smartphone-based scores and mean ratings of UPDRS item #23 (0.52; finger tapping), UPDRS #25 (0.47; rapid alternating movements of hands), UPDRS #31 (0.57; body bradykinesia and hypokinesia), sum of the three UPDRS items (0.46), dyskinesia (0.64), and TRS (0.59). When assessing the test-retest reliability of the scores it was found that, in general, the clinical scores had better test-retest reliability than the smartphone-based scores. Only the smartphone-based predicted scores on the TRS and dyskinesia scales had good repeatability with intra-class correlation coefficients of 0.51 and 0.84, respectively. Clinician-based scores had higher effect sizes than smartphone-based scores indicating a better responsiveness in detecting changes in relation to treatment interventions. However, the first principal component of the 37 features was able to capture changes throughout the levodopa cycle and had trends similar to the clinical TRS and dyskinesia scales. Smartphone-based scores differed significantly between patients and healthy controls.

    Conclusions

    Quantifying PD motor symptoms via instrumented, dexterity tests employed in a smartphone is feasible and data from such tests can also be used for measuring treatment-related changes in patients.

    Fysisk aktivitet hos personer som fått diagnosen transitorisk ischemisk attack (TIA) - behov av sjukgymnastråd2009Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie var att beskriva hur fysiskt aktiva personer som fått diagnosen TIA var. Frågeställningarna rörde vilka aktiviteter studiedeltagarna ägnade sig åt, hur de upplevde sin hälsa, begränsande faktorer, eventuell förändring av aktivitetsvanor, samt om deltagarna fått råd om fysisk aktivitet. Som metod valdes enkätundersökning och 195 enkäter skickades till personer som sökt Universitetssjukhuset Örebro 2007 och fått diagnosen TIA. Resultat: Svarsfrekvensen, efter externt och internt bortfall, blev 74 %. Mer än hälften av de 144 studiedeltagarna var fysiskt aktiva mindre än 30 minuter/dag. Den vanligaste aktiviteten var promenader, vilket 72 % ägnade sig åt. Yngre personer ägnade sig oftare åt tre eller fler aktiviteter jämfört med äldre personer. De deltagare som var regelbundet fysiskt aktiva skattade sin hälsa som god till utmärkt, medan de med stillasittande fritid skattade sin hälsa som någorlunda eller dålig. De mest begränsande faktorerna var sjukdom och smärta. Av studiedeltagarna uppgav 98 personer att de inte fått råd om fysisk aktivitet och hälften av deltagarna hade inte förändrat sina aktivitetsvanor. Slutsats: Studien visar att många personer som fått diagnosen TIA är fysiskt inaktiva. Begränsande faktorer, som, sjukdom, smärta och hög ålder, medför att råd om fysisk aktivitet bör vara individanpassade. Att ge råd om fysisk aktivitet på lämplig nivå, utifrån den enskilde personens förutsättningar är ett centralt kunskapsområde för sjukgymnaster. Därför bör dessa patienter ges möjlighet att träffa sjukgymnast.

    Utomhuspedagogik: pedagogers syn på utomhuspedagogik2006Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning

    Syftet med föreliggande uppsats är att belysa vilken betydelse pedagoger inom förskola och skola anser att utomhuspedagogik har för barns lärande och utveckling.

    Vidare är syftet att orientera om hur och varför pedagoger inom förskola och skola använder utomhuspedagogik. Två olika frågeställningar ligger som till grund för vår uppsats.

    Dessa är:

    Vad anser pedagoger inom förskola och skola om betydelsen av utomhuspedagogik för barns lärande och utveckling?

    Hur använder pedagoger inom förskola och skola utomhuspedagogik och varför?

    För att nå syftet har vi valt att genomföra en kvalitativ intervjustudie. Vi har intervjuat fem olika pedagoger på två olika skolor och två olika förskolor. Dessa förskolor/skolor ligger i Mellansverige och närheten till naturen ser olika ut vid dessa förskolor och skolor.

    Efter genomförda intervjuer kan vi se att pedagogernas syn på utomhuspedagogik är mycket positiv och att de flesta pedagoger använder sig av utomhuspedagogik i någon utsträckning. Pedagogerna anser att utomhuspedagogiken ger barnet en större möjlighet att uppleva med flera sinnen samt att det kan vara bra för barn som är lite oroliga inomhus och behöver röra på sig för att lära. Vi kan även se att förskolorna använder sig av utomhuspedagogik i större utsträckning än vad man gör i skolan.

    Factors associated with work ability in patients with chronic whiplash-associated disorder grade II-III: a cross-sectional analysis2015In: Journal of Rehabilitation Medicine, ISSN 1650-1977, E-ISSN 1651-2081, Vol. 47, no 6, p. 546-551Article in journal (Refereed)
    Abstract [en]

    Objective: To investigate the factors related to self-perceived work ability in patients with chronic whiplash-associated disorder grades II-III.

    Design: Cross-sectional analysis.

    Patients: A total of 166 working age patients with chronic whiplash-associated disorder.

    Methods: A comprehensive survey collected data on work ability (using the Work Ability Index); demographic, psychosocial, personal, work- and condition-related factors. Forward, stepwise regression modelling was used to assess the factors related to work ability.

    Results: The proportion of patients in each work ability category were as follows: poor (12.7%); moderate (39.8%); good (38.5%); excellent (9%). Seven factors explained 65% (adjusted R-2 = 0.65, p < 0.01) of the variance in work ability. In descending order of strength of association, these factors are: greater neck disability due to pain; reduced self-rated health status and health-related quality of life; increased frequency of concentration problems; poor workplace satisfaction; lower self-efficacy for performing daily tasks; and greater work-related stress.

    Conclusion: Condition-specific and psychosocial factors are associated with self-perceived work ability of individuals with chronic whiplash-associated disorder.

    Riskfaktorer till våldsbrott -En systematisk litteraturstudie om sociala riskfaktorer till våldsbrottslighet bland ungdomar 2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Studien är en systematisk litteraturöversikt vars syfte är att med utgångspunkt i tidigare forskning, sammanställa och beskriva den forskning som undersöker sociala riskfaktorer till ungdomars våldsbrottslighet. Detta för att skapa en tydlighet över de sociala riskfaktorerna samt att förstå hur sociala riskfaktorer kan ge utfallet våldsbrottslighet bland ungdomar. Totalt har 15 internationella studier av kvantitativ karaktär inkluderats i litteraturöversikten. All data har sammanställts och strukturerats upp i en tabell. Resultatet har därefter tematiserats utifrån dess nyckelfynd i en tematisk analys. För en fördjupad förståelse har resultatet också analyserats utifrån social inlärningsteori och anknytningsteorin. Resultat visar att de mest frekventa sociala riskfaktorerna finns inom familj- och uppväxt, skola- och umgänge och grannskap. Av dessa kategorier har familj och uppväxt framkommit som den mest betydande sociala riskfaktorn till ungdomars våldsbrottslighet, vilket framförallt avser fysiskt och psykiskt våld, försummelse, sexuella övergrepp eller andra brister i omvårdnaden under barndomen. Detta förklaras genom att individer, som under barndomen, vistats i en utsatt miljö tenderar att observera och efterlikna omgivningens beteende och därmed själv utveckla ett normbrytande och våldsamt beteende i ungdomsåren. Sammanfattningsvis har det framkommit att kontextuella förhållanden har en stor inverkan på utvecklandet av ungdomars våldsbrottslighet. Det har också framkommit att riskfaktorer är komplexa och samspelar på olika nivåer och förstärker effekterna av varandra, vilket medför en svårighet att förutse dess utfall.

    Abstract [en]

    This essay studies what affects individual’s political participation in Sweden. Specifically, it

    examines what affects resources, motivation and networks has on individual’s political

    participation and if these effects have a greater or lesser impact during election year compared

    to non- election year. The study applies the civic voluntarism model as theory. According to

    the theory, individuals who are more motivated and have a good access to resources and

    networks participate more in politics. This study relies on a quantitative method completed

    with a logistic regressions analysis and the empirical data used was obtained from SOMinstitute,

    Gothenburg University. Our research concluded that individuals with more access to

    resources, networks and high political motivation are more likely to participate in the politics

    of Sweden. Furthermore, the study revealed that effects of motivation and network has a

    stronger impact on individual’s political participation in Sweden under election year compared

    to non-election year.

    Alexanderteknik för emotionellt uttryck i musik: Alexanderteknik som metod för en effektiv spelteknik, och en tillfredsställande musikalisk framställning riktat huvudsakligen till den klassiska gitarristen2009Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In this essay, I want to achieve an accessible and applicable entrance to Alexander Technique as a method for learning to use the body in such a way as to allow emotional expression in music. It is necessary to see the real need of Alexander Technique for the active musician, and therefore important components of music-making will be presented. These components are presented from an Alexander-perspective in order to produce a clear picture of the method of application.The prerequisite for emotional expression in music is musicians and music listeners with the ability to generate, and respond after emotional impressions. Alexander Technique provides an approach to make it easier for musicians, especially guitarists, to express emotions in a performance situation.After years of practice and obtaining musical knowledge and practical skills at the instrument, it is common that muscle tension and ingrained patterns contribute to limited expression. Muscle tensions arising from pressured situations such as auditions, competitions and concerts. Repetitive movements contribute to this, and lays the foundation for an insufficient technique. It is clear that traditional learning methods need to be complemented with an approach that treats body awareness as an essential part of musical performances. The notion that the use of the body affects mental states is now a truism, and one can see an opening towards new approaches that facilitate learning as well as performance of musical works. The emotional expression is in focus here, and this study deals with musical production based on the philosophy that music should be driven by decisions involving emotional expression.

    Highlighting clinical needs in Clostridium difficile infection: the views of European healthcare professionals at the front line2015In: Journal of Hospital Infection, ISSN 0195-6701, E-ISSN 1532-2939, Vol. 90, no 2, p. 117-125Article in journal (Refereed)
    Abstract [en]

    Background: Clostridium difficile infection (CDI) is the leading cause of infectious nosocomial diarrhoea in Europe. Despite increased focus, its incidence and severity are increasing in many European countries. Aim: We developed a series of consensus statements to identify unmet clinical needs in the recognition and management of CDI. Methods: A consortium of European experts prepared a series of 29 statements representing their collective views on the diagnosis and management of CDI in Europe. The statements were grouped into the following six broad themes: diagnosis; definitions of severity; treatment failure, recurrence and its consequences; infection prevention and control interventions; education and antimicrobial stewardship; and National CDI clinical guidance and policy. These statements were reviewed using questionnaires by 1047 clinicians involved in managing CDI, who indicated their level of agreement with each statement. Findings: Levels of agreement exceeded the 66% threshold for consensus for 27 out of 29 statements (93.1%), indicating strong support. Variance between countries and specialties was analysed and showed strong alignment with the overall consensus scores. Conclusion: Based on the consensus scores of the respondent group, recommendations are suggested for the further development of CDI services in order to reduce transmission and recurrence and to ensure that appropriate diagnosis and treatment strategies are applied across all healthcare settings.

    Crime Prevention in the EU2006Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Crime prevention became an important Union issue when the Treaty of Amsterdam came into force and created an area of Freedom, Security and Justice (AFSJ). In 1999 the Tampere Conclusions declared the first crime preventive priorities along with the Union’s obligation to protect its citizens. Two years later the European Crime Prevention Network (EUCPN) was established and it was then stated that crime prevention should be based on knowledge and carried out through cooperation and an increased inter-state exchange of information. The Member States have the main responsibility and the work should be carried out by a multidisciplinary approach specialising on certain selected priorities. Successful practices need to be exchanged within the network and evaluation of the preventive work must be done. Despite these and other guidelines, crime preventive work has proven to be problematic. The practical problems are that proven theories are not used in the actual work, the lack of resources and evaluation methods, and too broad priorities which reflects the politicians’ unrealistic ambitions. The theoretical problems, in contrast, are the increased importance for security that collides with basic human rights and the concept of freedom, the lack of consideration for the States’ differences and the idea that States’ providence of security is a source of legitimacy.

    Closing the gaps: Improving literacy and mathematics by ict-enhanced collaboration2016In: Computers and education, ISSN 0360-1315, E-ISSN 1873-782X, Vol. 99, p. 68-80Article in journal (Refereed)
    Abstract [en]

    Literacy and mathematics are necessary skills that for different reasons unfortunately not everybody acquires sufficiently. In OECD countries there is also a gender gap; boys lag behind girls in literacy but often outperform girls in mathematics (OECD, 2012). ICT (Information and communication technologies) may contribute useful tools to address both these problems but in order to effectively create better educational conditions there is yet a need to develop effective methods that combine ICT with key factors for learning. This research contributes to this by measuring effects of the “Write to Learn” (WTL) method. WTL lets children from 1st grade use several ICT tools to write texts and subsequently discuss and refine them together with classmates and teachers using digital real-time formative feedback and assessment. The central learning factor addressed, in mathematics as well as in literacy, is the written communication allowing the learners to interact with peers and teachers. WTL draws on methods from socio-cultural theory, including continuous social interaction and written real-time formative feedback among peers, using shared electronic forums for collaboration, thereby providing social meaning and increased learning of literacy and mathematics, among both boys and girls.

    The study uses quantitative methods and two control groups, one using traditional method (no ICT) and one using technology individually (without integrated social interaction and formative feedback), to compare results from 502 students in grade 3 national tests in mathematics and literacy. WTL yields by far best results; higher average score both in literacy and mathematics, smaller gender gap, and significantly better results for the under-achievers. The ITU method performs worst, which shows that ICT use must be well integrated into the pedagogy to be useful.

    Disseminating digital innovation in school - leading second-order educational change2019In: Education and Information Technologies: Official Journal of the IFIP technical committee on Education, ISSN 1360-2357, E-ISSN 1573-7608, Vol. 24, no 5, p. 3021-3039Article in journal (Refereed)
    Abstract [en]

    Using digital technology effectively in schools requires profound changes in traditional teaching and learning activities. Pedagogical innovations often start small-scale and developing good ideas into shared practice across schools is challenging in many ways, especially if the innovation requires second-order change, i.e. challenges to fundamental beliefs about teaching and learning. This study investigates how a validated pedagogical method requiring integrated Information and Communication Technology (ICT) use and second-order change can be disseminated and sustained over time. We surveyed 92 primary school teachers who at different times over a 5-year period participated in a training course designed to implement an innovative technology-supported teaching method, Write To Learn, across an entire city. We found that organized teacher development programs can drive second-order change, but this requires considerable, active, and sustained effort from leaders at both school and district level. Additional factors include immediate and extended social systems and handling diversity among teachers. The results are useful for both practitioners and researchers since they contribute to a deeper understanding of the opportunities and challenges involved in disseminating effective ICT-based methods that requires profound changes of thinking about teaching and learning to guide the transformation of teaching practice.

    Relationsskapande i socialt arbete: Fyra socialarbetares upplevelser av, åsikter om och strategier för att skapa goda relationer till sina klienter vid en daglig verksamhet.2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning

    Det övergripande syftet med denna uppsats är att undersöka hur personal på en daglig verksamhet upplever skapandet av relationer med sina klienter på verksamheten, samt vad personalen beskriver som viktigt i och vilka strategier de använder sig av i skapandet av relationer till sina klienter. I studien genomförs fyra intervjuer med personal på en dagligverksamhet. Resultatet analyserades och strukturerades upp med ett hermeneutiskt förhållningssätt och kvalitativ innehållsanalys, samt belystes därefter utifrån tidigare forskning och teorier i Emotionell Intelligens, att "använda sig själv", Mentalisering och Anknytningsteori. Resultatet visar att personalen uppfattar relationen som en självklar del av deras arbete och en viktig del för utförandet av verksamheten. Relationen bidrar med trygghet, tillit och förtroende hos klienterna, som resultatet visar, utgör vitala delar för att en relation ska kunna skapas. Till hjälp i relationsskapandet använder sig personalen av sig själv som verktyg, personliga egenskaper, professionell arbetslivserfarenhet och individuellt erhållen kunskap kring varje klient. Resultatet bekräftar den forskning och de teorier som användes i studien. I relationskapande krävs det att socialarbetaren är empatisk, har en reflekterande förmåga kring sig själv, sina egna och klienters känslor, samt förmåga att kunna identifiera känslors ursprung och reglera dessa hos sig själv och i sina klienter

    UNDERSÖKNING AV OMSTÄLLNINGSTIDER OCH VARIATIONER VID KARTONGMASKIN 2: EN FALLSTUDIE PÅ IGGESUND PAPERBOARD AB, IGGESUND2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Iggesund Mill manufactures bleached board that is used in exclusive packaging. Iggesund Mill is a part of the Holmen Groupand is located almost 30 scandinavian miles north of Stockholm. A strategic initiative has been launched at Iggesund Mill, which includes improving the working environment, increasing participation and increasing the ability to produce high quality board.

    In this study, changeovers and the variations that occur on the board machine 2 (KM2)have been investigated. This work has been conducted as a qualitative case study where interviews and observations have been analyzed with theoretical support. Early in the study it proved difficult to determine the changeover times at KM2. This may be due to an uncertainty regarding how to report changeovers, which creates a misleading picture of the changeover problems. The conclusion of this is that Iggesund Mill should clearly define the term "Changeover". The variety of products also leads to a lot of changeovers which leads to variations in the process that adversely affect the productivity. A recommendation for a continued work is to investigate whether the product variety can be reduced or the possibility to run larger production cycles.
