    Esophageal- and Gastroesophageal Junctional Cancer: Aspects on Staging, Treatment and Results2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Esophageal- and gastroesophageal junctional (GEJ) cancer is the sixth cause of cancer-related death worldwide. Some improvements in care are attributed to nationwide disease-specific registries, preoperative staging and increased understanding of mechanisms affecting patient selection. Surgery, however, is a cornerstone for treatment where minimally invasive surgery and increased understanding of perioperative physiology may be beneficial. The aims of this thesis were to validate the Swedish national registry for esophageal and gastric cancer (NREV) and to explore mechanisms in patient selection, perioperative physiology, treatment-related outcomes and staging.

    A validation study with re-abstracted data on 400 patients determined NREV comparable to other similar registries and to have a completeness of 95.5 %. Overall accuracy was 91.1 % throughout the registry and timeliness to reporting was adequate.

    In a cohort of 4112 patients from NREV, high education level was associated with an increased probability of being allocated to curative treatment, as was the presence of a multidisciplinary treatment conference. High education level was associated with improved survival.

    By measuring intramucosal pH (pHi) in 32 patients, to describe perfusion in the gastric conduit during esophagectomy, a reduction in perfusion was seen at all surgical steps altering vascular supply to the conduit but foremost after gastric tube construction by linear stapling. Patients with low pHi on the first postoperative day were more prone to anastomotic insufficiency.

    In 116 patients undergoing esophagectomy (65 open and 51 minimally invasive), a retrospective cohort study regarding surgical oncological results and postoperative complications was conducted. Lymph node yield was increased, peroperative blood loss and in-hospital stay were reduced with minimally invasive esophagectomy. Postoperative complications were unaffected by surgical approach. 

    In a prospective study of nineteen patients, whole-body integrated PET/MRI was compared to PET/CT in preoperative staging. PET/MRI was safe and feasible. Accuracy and correlations between modalities were good regarding tumor characteristics and N- and M-staging. In T-staging there were discrepancies indicating differences between modalities.

    The thesis presents data on the quality of NREV for future research and elaborates on patient selection, staging, perioperative physiology and treatment-related outcomes for patients with esophageal- and GEJ cancer.

    Look-ahead control for fuel-efficient and safe heavy-duty vehicle platooning2018Doktoravhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    The operation of heavy-duty vehicles at small inter-vehicular distances, known as platoons, lowers the aerodynamic drag and, therefore, reduces fuel consumption and greenhouse gas emissions. Tests conducted on flat roads have shown the potential of platooning to reduce the fuel consumption of about 10%. However, platoons are expected to operate on public highways with varying topography alongside other vehicles. Due to the large mass and limited engine power of heavy-duty vehicles, road slopes have a significant impact on feasible and optimal speed profiles. For single vehicles, experiments have shown that optimizing the speed according to the road profile resulted in fuel saving of up to 3.5%. The use of such a look-ahead control framework is expected to lead to large benefits also for platooning.

    This thesis presents the design of safe and fuel-efficient control of heavy-duty vehicle platoons driving on realistic road profiles. The scenario where the platooning vehicles cooperate to optimize their overall fuel-efficiency is studied together with the scenario where the vehicles do not explicitly cooperate.

    First, we propose a control architecture that splits the cooperative platooning control problem into two layers. The top layer computes a reference speed profile that ensures fuel-efficient operation of the entire platoon based on dynamic programming. The bottom layer relies on model predictive control to safely track the reference speed. Simulations show the ability of the proposed controller to save up to 12% of fuel for following vehicles compared to existing platoon controllers and to safely react to emergency braking of the leading vehicle.

    Second, we propose a gear management layer that fits in the cooperative platooning control architecture and explicitly takes the gear selection into account. The underlying optimal control problem aims at minimizing the vehicle fuel consumption and the reference tracking deviations. Simulations indicate how this formulation outperforms existing alternatives, both in terms of fuel-efficiency and tracking error.

    Third, we address non-cooperative platooning by proposing a vehicle-following controller suitable for fuel-efficient control of heavy-duty vehicles. The proposed controller explores both the benefits given by the short inter-vehicular distance and those given by pulse-and-glide, i.e., alternating traction and coasting phases. A simulation study suggests fuel saving of up to 18% compared to the single vehicle case, and up to 7% compared to when a constant-distance vehicle-following controller is used.

    Last, we propose a vehicle-following controller aimed at exploiting long preview of the preceding vehicle trajectory by directly manipulating the inputs of low-level vehicle controllers. This is achieved through a model predictive controller that uses a short prediction horizon and includes a terminal state set that incorporates preview information about the preceding vehicle. Experiments indicate the ability of the controller to avoid unnecessary braking, while simulations show behavior similar to the optimal control behavior.

    Transverse-momentum-dependent multiplicities of charged hadrons in muon-deuteron deep inelastic scattering2018Inngår i: Physical Review D: covering particles, fields, gravitation, and cosmology, ISSN 2470-0010, E-ISSN 2470-0029, Vol. 97, nr 3, artikkel-id 032006Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A semi-inclusive measurement of charged hadron multiplicities in deep inelastic muon scattering off an isoscalar target was performed using data collected by the COMPASS Collaboration at CERN. The following kinematic domain is covered by the data: photon virtuality Q(2) > 1 (GeV/c)(2), invariant mass of the hadronic system W > 5 (GeV/c)(2), Bjorken scaling variable in the range 0.003 < x < 0.4, fraction of the virtual photon energy carried by the hadron in the range 0.2 < z < 0.8, and square of the hadron transverse momentum with respect to the virtual photon direction in the range 0.02 (GeV/c)(2) < P-hT(2) < 3 (GeV/c)(2). The multiplicities are presented as a function of P-hT(2) in three-dimensional bins of x, Q(2), z and compared to previous semi-inclusive measurements. We explore the small-P-hT(2) region, i.e. P-hT(2) < 1 (GeV/c)(2), where hadron transverse momenta are expected to arise from nonperturbative effects, and also the domain of larger P-hT(2), where contributions from higher-order perturbative QCD are expected to dominate. The multiplicities are fitted using a single-exponential function at small P-hT(2) to study the dependence of the average transverse momentum < P-hT(2)> on x, Q(2) and z. The power-law behavior of the multiplicities at large P-hT(2) is investigated using various functional forms. The fits describe the data reasonably well over the full measured range.

    Novel hydrophilic and hydrophobic amorphous silica: Characterization and adsorption of aqueous phase organic compounds2018Inngår i: Adsorption Science and Technology, ISSN 0263-6174, E-ISSN 2048-4038, Vol. 36, nr 1-2, s. 327-342Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Very few studies have investigated the adsorption performance of hydrophobic and hydrophilic silicas with dissolved organics in water, which is a required final step during produced water treatment. The cost of functionalization also hinders the use of hydrophobic materials as sorbents. Novel hydrophilic silicas, prepared at low temperature and ambient pressure, were characterised by SEM, FTIR and BET analysis, and studied for the adsorption of aqueous phase organic compounds at concentrations below their solubility limits. Adsorption capacities were found to be up to 264 mg/g for benzene and 78.8 mg/g for toluene. Direct comparison is made with the analogous hydrophobic version of one of the silica materials, demonstrating comparable uptakes for benzene concentrations lower than 50 mg/L. This finding supports the hypothesis that, at very low aqueous phase organic concentrations, hydrophobicization has no discernible effect on access of the pollutants to the internal porosity of the material.

    Five-dimensional fermionic Chern-Simons theory2018Inngår i: Journal of High Energy Physics (JHEP), ISSN 1126-6708, E-ISSN 1029-8479, artikkel-id 037Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We study 5d fermionic CS theory with a fermionic 2-form gauge potential. This theory can be obtained from 5d maximally supersymmetric YM theory by performing the maximal topological twist. We put the theory on a five-manifold and compute the partition function. We find that it is a topological quantity, which involves the Ray-Singer torsion of the five-manifold. For abelian gauge group we consider the uplift to the 6d theory and find a mismatch between the 5d partition function and the 6d index, due to the nontrivial dimensional reduction of a selfdual two-form gauge field on a circle. We also discuss an application of the 5d theory to generalized knots made of 2d sheets embedded in 5d.

    Time evolution of the CO2 hydrogenation to fuels over Cu-Zr-SBA-15 catalysts2018Inngår i: Journal of Catalysis, ISSN 0021-9517, E-ISSN 1090-2694, Vol. 362, s. 55-64Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Time evolution of catalytic CO2 hydrogenation to methanol and dimethyl ether (DME) has been investigated in a high-temperature high-pressure reaction chamber where products accumulate over time. The employed catalysts are based on a nano-assembly composed of Cu nanoparticles infiltrated into a Zr doped SiOx mesoporous framework (SBA-15): Cu-Zr-SBA-15. The CO2 conversion was recorded as a function of time by gas chromatography-mass spectrometry (GC-MS) and the molecular activity on the catalyst’s surface was examined by diffuse reflectance in-situ Fourier transform infrared spectroscopy (DRIFTS). The experimental results showed that after 14 days a CO2 conversion of 25% to methanol and DME was reached when a DME selective catalyst was used which was also illustrated by thermodynamic equilibrium calculations. With higher Zr content in the catalyst, greater selectivity for methanol and a total 9.5% conversion to methanol and DME was observed, yielding also CO as an additional product. The time evolution profiles indicated that DME is formed directly from methoxy groups in this reaction system. Both DME and methanol selective systems show the thermodynamically highest possible conversion.

    On the representability of cones of monotone functions in weighted Lebesgue spaces and the extrapolation of operators on these cones2017Inngår i: Algebra i Analiz, ISSN 0234-0852, Vol. 29, nr 4, s. 1-44Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We have proved that boundedness of a sublinear operator on the cone of monotone functions is equivalent to boundedness of the involved operator with it on a new space, which is constructively built. Using this construction we were able to prove a new extrapolation theorems on this cone in weighted Lebesgue spaces.

    High prevalence of gait abnormalities in pugs2018Inngår i: The Veterinary Record, ISSN 0042-4900, E-ISSN 2042-7670, Vol. 182, nr 6, artikkel-id 167Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The objective of this prospective study was to determine the prevalence of gait abnormalities in a cohort of Swedish pugs by using an owner-based questionnaire targeting signs of gait abnormality and video footage showing the dog's gait. This study also evaluated associated conditions of abnormal gait, including other health disorders prevalent in the breed. Five hundred and fifty (550) pugs registered in the Swedish Kennel Club, of one, five and eight years of age, in 2015 and 2016, were included in the study. Gait abnormalities were reported in 30.7 per cent of the responses. In the majority of cases, the character of the described gait indicated a neurological cause for the gait abnormality. An association was observed between abnormal gait and age, with gait abnormalities being significantly more common in older pugs (P=0.004). An association was also found between abnormal gait and dyspnoea, with dyspnoea being significantly more common in pugs with gait abnormalities (P<0.0001). This study demonstrated that the prevalence of gait abnormalities was high in the Swedish pug breed and increased with age. Future studies on the mechanisms behind these gait abnormalities are warranted.

    Early life swimming pool exposure and asthma onset in children: a case-control study2018Inngår i: Environmental health, ISSN 1476-069X, E-ISSN 1476-069X, Vol. 17, artikkel-id 34Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Trichloramine exposure in indoor swimming pools has been suggested to cause asthma in children. We aimed to investigate the risk of asthma onset among children in relation to individual trichloramine exposure.

    METHODS: A longitudinal nested case-control study of 337 children with asthma (cases) and 633 controls aged 16-17 years was performed within a population-based cohort from The Obstructive Lung Disease in Northern Sweden studies (OLIN). Year of asthma onset and exposure time at different ages were obtained in telephone interviews. Trichloramine concentrations in the pool buildings were measured. Skin prick test results for inhalant allergens were available from previous examinations of the cohort. The risk for asthma was analyzed in relation to the cumulative trichloramine exposure before onset of asthma.

    RESULTS: ). Swimming pool exposure in early life was associated with a significantly higher risk of pre-school asthma onset. A dose-response relationship between swimming pool exposure and asthma was indicated in children with asthma onset at 1 year of age. Children who were both sensitized and exposed had a particularly high risk.

    CONCLUSIONS: Early life exposure to chlorinated swimming pool environments was associated with pre-school asthma onset.

    Safety Concerns Reported by Patients Identified in a Collaborative Signal Detection Workshop using VigiBase: Results and Reflections from Lareb and Uppsala Monitoring Centre2018Inngår i: Drug Safety, ISSN 0114-5916, E-ISSN 1179-1942, Vol. 41, nr 2, s. 203-212Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Introduction: Patient reporting in pharmacovigilance is important and contributes to signal detection. However, descriptions of methodologies for using patient reports in signal detection are scarce, and published experiences of how patient reports are used in pharmacovigilance are limited to a few individual countries.

    Objective: Our objective was to explore the contribution of patient reports to global signal detection in VigiBase. Methods Data were retrieved from VigiBase in September 2016. Drug-event-combination series were restricted to those with[50% patient reports, defined as reporter type "Consumer/non-health professional'' per E2B reporting standard. vigiRank was applied to patient reports to prioritize combinations for assessment. Product information for healthcare professionals (HCPs) as well as patient information leaflets (PILs) were used as reference for information on adverse drug reactions (ADRs). Staff from the Uppsala Monitoring Centre and the Netherlands Pharmacovigilance Centre Lareb categorized the combinations. Potential signals proceeded to a more in-depth clinical review to determine whether the safety concern should be communicated as a "signal.''

    Results: Of the 212 combinations assessed, 20 (9%) resulted in eight signals communicated within the World Health Organization (WHO) programme for international drug monitoring. Review of PILs revealed insufficient ADR descriptions for patients and examples of poor consistency with product information for HCPs. Patient narratives provided details regarding the experience and impact of ADRs and evidence that patients make causality and personal risk assessments.

    Conclusions: Safety concerns described in patient reports can be identified in a global database including previously unknown ADRs as well as new aspects of known ADRs. Patient reports provide unique information valuable in signal assessment and should be included in signal detection. Novel approaches to highlighting patient reports in statistical signal detection can further improve the contribution of patient reports to pharmacovigilance.

    Dabigatran vs. warfarin in relation to the presence of left ventricular hypertrophy in patients with atrial fibrillation-the Randomized Evaluation of Long-term anticoagulation therapY (RE-LY) study2018Inngår i: Europace, ISSN 1099-5129, E-ISSN 1532-2092, Vol. 20, nr 2, s. 253-262Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Aim: We tested the hypothesis that left ventricular hypertrophy (LVH) interferes with the antithrombotic effects of dabigatran and warfarin in patients with atrial fibrillation (AF).

    Methods and results: This is a post-hoc analysis of the Randomized Evaluation of Long-term anticoagulation therapY (RE-LY) Study. We defined LVH by electrocardiography (ECG) and included patients with AF on the ECG tracing at entry. Hazard ratios (HR) for each dabigatran dose vs. warfarin were calculated in relation to LVH. LVH was present in 2353 (22.7%) out of 10 372 patients. In patients without LVH, the rates of primary outcome were 1.59%/ year with warfarin, 1.60% with dabigatran 110 mg (HR vs. warfarin 1.01, 95% confidence interval (CI) 0.75-1.36) and 1.08% with dabigatran 150 mg (HR vs. warfarin 0.68, 95% CI 0.49-0.95). In patients with LVH, the rates of primary outcome were 3.21%/ year with warfarin, 1.69% with dabigatran 110 mg (HR vs. warfarin 0.52, 95% CI 0.32-0.84) and 1.55% with 150 mg (HR vs. warfarin 0.48, 95% CI 0.29-0.78). The interaction between LVH status and dabigatran 110 mg vs. warfarin was significant for the primary outcome (P = 0.021) and stroke (P = 0.016). LVH was associated with a higher event rate with warfarin, not with dabigatran. In the warfarin group, the time in therapeutic range was significantly lower in the presence than in the absence of LVH.

    Conclusions: LVH was associated with a lower antithrombotic efficacy of warfarin, but not of dabigatran, in patients with AF. Consequently, the relative benefit of the lower dose of dabigatran compared to warfarin was enhanced in patients with LVH. The higher dose of dabigatran was superior to warfarin regardless of LVH status.

    Quality in Validation of Prior Learning: Experiences from Work with the Nordic Model for Quality in Validation of Prior Learning2017Rapport (Annet vitenskapelig)
    Abstract [en]

    Validation has become a central element in educational policies around the world. In the Nordic countries validation has been practiced especially in the vocational education and training sector (VET) for the past 15–20 years.

    This report explores the question of quality in validation, first by introducing the concept in general and secondly in detail by describing the Nordic Model for quality in validation. The

    researchers were testing the Model in VET institutions in a project coordinated by the Nordic Network on Adult Learning (NVL). Find- ings from the interactive research are presented from a sample of three colleges situated in Denmark, Finland and Sweden. The Nor- dic Model can be seen as a structured way to assess the current sit- uation in validation at an institutional level and to identify areas of development. The research does not focus on the quality itself, but on the process of quality work and the process in the cases.

    In conclusion, the work with the cases speaks for the useful- ness of the Nordic Quality Model for validation as a comprehensive structure for developing the validation system in vocational educa- tion and training.

    Phylogenetic position and taxonomy of Kusaghiporia usambarensis gen. et sp. nov. (Polyporales)2018Inngår i: Mycology, ISSN 2150-1203Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A large polyporoid mushroom from the West Usambara Mountains in North-eastern Tanzania produces dark brown, up to 60-cm large fruiting bodies that at maturity may weigh more than 10 kg. It has a high rate of mycelial growth and regeneration and was found growing on both dry and green leaves of shrubs; attached to the base of living trees, and it was also observed to degrade dead snakes and insects accidentally coming into contact with it. Phylogenetic analyses based on individual and concatenated data sets of nrLSU, nrSSU and the RPB2 and TEF1 genes showed it, together with Laetiporus, Phaeolus, Pycnoporellus and Wolfiporia, to form a monophyletic group in Polyporales. Based on morphological features and molecular data, it is described as Kusaghiporia usambarensis.

    Impact of flat-top voltage waveform distortion on harmonic current emission and summation of electronic household appliances2018Inngår i: Renewable Energy and Power Quality Journal, ISSN 2172-038X, Vol. 1, nr 16, s. 698-703, artikkel-id 437Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Electronic household appliances are non-linearloads and emit harmonics into the low voltage networks.Usually, these loads are simply modelled by constantcurrent source models, which only represent the harmonicemission of the appliances for a single supply voltagedistortion, mostly sinusoidal conditions.Measurements have shown that the harmonic currentsemitted by electronic devices can significantly depend onthe circuit topology and the existing supply voltagedistortion. This paper studies the impact of supply voltagedistortion, which can be typically found in public lowvoltage networks (so-called flat-top voltage waveform), onthe harmonic current emission of individual devices withdifferent circuit topologies as well as the impact of supplyvoltage distortion on the harmonic summation of thesedevices.

    Reasoning and proving in mathematics teacher education2017Inngår i: Proceedings of the Third ERME Topic Conference on Mathematics Teaching, Resources and Teacher Professional Development / [ed] S. Zehetmeier, B. Rösken-Winter, D. Potari, & M. Ribeiro, Berlin: European Society for Research in Mathematics Education, 2017, s. 197-206Konferansepaper (Fagfellevurdert)
    Abstract [en]

    There is evidence for recommendations to link mathematics teacher education (MTE) closely to school mathematics and to emphasise proving why rather than proving that when teaching reasoning and proof (R&P) in schools. In spite of that we suggest not to take the implication that MTE focuses on proving why to extremes. We outline the background, framework, and results of a pilot to an intervention study that seeks to address the problems of R&P in MTE. The results suggest that teachers face more problems with R&P than expected and have difficulties just selecting situations from school in need of a mathematical justification, let alone developing justifications and supporting their students’ learning of R&P. This supports our suggestion that a dual emphasis on proving that and proving why is needed in MTE

    Music festivals in Sweden - an analysis of the ten largest commercial festivals 2000 - 20132014Rapport (Annet vitenskapelig)
    Abstract [en]

    This study examines the development for commercial music festivals in Sweden during the time period 2000 - 2013. Although it is clear that some legendary Swedish music festivals have disappeared during the latest years, this study indicates that the number of paying visitors of the largest festivals continues to increase. In fact, 2013 was the record year during the studied time frame regarding the number of paying visitors to the ten largest commercial festivals, with official visitor figures validated through STIM data. Nevertheless, the Swedish music festival market has changed considerably. The purpose of the paper is to describe some of these changes as well as provide a quantitative foundation for further research questions to be dealt with in the future.

    From products to consumption: changes on the Swedish music market as a result of streaming technologies2013Rapport (Annet vitenskapelig)
    Abstract [en]

    Since the year 2009, the Swedish music market has changed drastically. In the first six months of 2013, 75 percent of total revenues to Swedish repertoire owners came from digital distribution. More than 90 percent of those revenues came from streaming. More than half of the population has a streaming subscription, and streaming has become the dominant format for consuming music on this specific market. As a result of this paradigm shift, changes have occurred in the Swedish music industrial system, as well as in user behaviors. This report examines how the Swedish music market has changed as a result of à la carte on demand streaming, explains the streaming model as such and give a picture of what these changes could mean for the future.

    Emerging and conflicting business models for music content in the digital environment2008Inngår i: Collaboration and the knowledge economy: issues, applications, case studies / [ed] Paul Cunningham & Miriam Cunningham, IOS Press, 2008, Vol. 5Konferansepaper (Fagfellevurdert)
    Abstract [en]

    As music listening is moving from tangible products to digital services, record labels seem to have difficulties in adjusting their business models to the new reality. This study investigates how Swedish record labels have changed their practices and habits when it comes to marketing, promoting as well as selling music. The 360-degree model - more or less used by all majors - where the label owns or partly owns related rights is one clear tendency. A contrary tendency is split risk cooperation found mainly among the independent record companies and their acts. This is one example of the different practises that can be observed in a market where long-time strategies seem to be hard to draw simply because there is not enough knowledge on how the market will evolve, not even on short-term basis.

    Semi-presidentialism and Inclusive Governance in Ukraine: Reflections for Constitutional Reform2018Rapport (Fagfellevurdert)
    Abstract [en]

    This report assesses the ways in which the semi-presidential form of government can be best structured to promote stable, democratic and inclusive governance in Ukraine.

    Constitutional stability in Ukraine has faced four main challenges: (a) recurring institutional conflict among the president, legislature and government; (b) a presidency that has fallen prey to autocratic tendencies; (c) a fragmented and weak party system that has undermined the capacity of the legislature to act coherently; and (d) a weak constitutional culture and a weak Constitutional Court.

    The report presents comparative knowledge from other semi-presidential systems, and reflections on the Ukrainian context, which could benefit a wide range of stakeholders, such as legislators, policy advisors, think tanks and civil society. It is based on an earlier report, Semi-Presidentialism as Power Sharing: Constitutional Reform after the Arab Spring, co-published by International IDEA and the Center for Constitutional Transitions in 2014.

    Psychosocial Perspectives on Working Conditions among Men and Women in Reindeer Breeding in Sweden2017Inngår i: Journal of Northern Studies, ISSN 1654-5915, Vol. 11, nr 2, s. 31-47Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective: The aim of this project was to describe the work organisation in the Sami communities and in reindeer-herding work and to explore the range of female duties and compare how men and women experience their psychosocial working conditions. Design: A kind of intervention study was performed by means of a questionnaire sent out to 200 individuals from seven Sami communities. Questions were asked about work organisation, communication, personal relations, solitary work, support, participation and appreciation from colleagues and women's tasks. Meetings and discussions were held about what was perceived as being important in the life of the Sami communities. Notes from 16 group discussions were written down and analysed according to themes of topics relating to how men and women in the Sami communities experience their lives. Results: Communication and relations were described as being inadequate and some respondents experienced a heavy workload. The women reported more troubled relations, less participation in decision-making and less appreciation from colleagues. Positive issues reported were the Sami identity and a strong connection to the reindeer and to nature. Conclusions: This study indicates a need for a more systematic study of the psychosocial work conditions in the Sami communities in Sweden. Measures should be taken to develop the organisation of work, e.g. through developing communication strategies and conflict management, which has been requested by several Sami communities.

    Ab initio modelling of interfaces in nanocomposites for high voltage insulation2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Dielectric nanocomposite materials have been experimentally proven to have properties that are beneficial in applications for efficient energy transport. However, today there are still no empirical models or rules that can predict the performance of a certain combination of materials in the nanocomposite, and there are also no definitive explanations of their dielectric behavior. A deeper understanding of the phenomena behind these materials' response to an applied electric field can open new possibilities for improvement of the insulating properties of nanocomposites.

    The goal of this work is to locate the key processes that are responsible for dielectric performance. The methodology of the study is based on ab initio technology, that relies solely on the knowledge of chemical and structural composition of the material. In this work, the charge-related properties of nanocomposite interfaces are studied. The primary material of the study is chosen to be polyethylene-based composite with magnesium oxide nanoparticles.

    The impact of the nanoparticle crystal surface termination and its silane treatment on the electronic structure of the interface between MgO and polyethylene are investigated here. Moreover, the effects of presence of carboxyl defect and water molecule near the interface are considered in this work as well.

    Based on the calculated electronic structure data, a model for charge dynamics is proposed. The model explains mechanisms for conductivity and space charge reduction in nanocomposites, but also predicts an increase in thermal stress and susceptibility for chemical defects. It is suggested here that the suppression mechanisms for space charge and conductivity in nanocomposites are inherently unstable and can also accelerate material aging.

    Impact of Pain and Evaluation of Education and Self-Care in Patients with Head and Neck Cancer2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    It is not unusual for patients with head and neck cancer (HNC) to suffer from both tumor and treatment-related pain that is difficult to alleviate despite individualized pharmacological treatment.

    The presence of concomitant various dimensions of pain in patients during the often difficult period following radiotherapy (RT) has not been elucidated. Several aspects concerning the importance of relatives for HNC patients have been addressed. However, little attention has been given to how relatives perceive patients with HNC pain and it is important to further elucidate this sparsely studied topic. Knowledge about health-related quality of life (HR-QoL) in this patient group during early RT is limited and needs to be assessed in relation to diagnosis and treatment. Self-care (SC) refers to what patients do on their own to achieve, maintain, and promote optimal health and may help reduce pain for several pain conditions. The impact of patient education and SC on pain and other common HNC symptoms need further clarification.

    The aims of this thesis were:

    1. to describe experiences and perceptions of pain in patients with HNC shortly after RT
    2. to describe how relatives perceived the patient’s situation, especially concerning pain, and how they experienced their own situation
    3. to identify factors that impact HR-QoL during early RT
    4. to develop effective pain management strategies, maintain activities of daily living, and promote HR-QoL in patients with HNC undergoing RT using patient education and SC instruction.

    In paper I patients with HNC described existential pain – expressed as fear of death, meaninglessness and guilt – already during and shortly after RT. Physical pain, psychological distress and social withdrawal played a significant role. Patients with HNC who were treated with RT should also proactively be offered treatment for the various dimensions of pain.

    In paper II relatives described their mental stress in response to a challenging situation that required their active support to help ease the patient's difficult condition. The interviews with relatives also revealed a lack of personal knowledge and frustration over the inability to participate in patient care, as well as inadequate support from the healthcare system. Early interventions from the healthcare system on behalf of the relatives may be necessary to meet these needs.

    In Paper III regression models revealed that pain intensity and symptoms of depression adversely affected HR-QoL in patients with HNC during early RT. Customized prehabilitation programs aimed at preventing pain and symptoms of depression could help preserve good HR-QoL.

    Paper IV assessed individual patient education and SC initiatives that resulted in a tendency for lower pain intensity during a portion of RT. One way to potentially enhance the benefits of education and SC could be to improve for example patient motivation and self-efficacy, as well as to optimize supportive efforts from caregivers.

    In conclusion, by identifying factors that can impact HR-QoL and evaluating the effect of patient education and SC, this thesis contributes to knowledge on perceived pain and the patient’s situation during and shortly after RT in patients with HNC and their relatives. This thesis points to the need for evaluation and further development of patient education and effective SC strategies for pain in patients with HNC undergoing RT, as well as for development and evaluation of support strategies for patients with pain and their families during and after RT.

    How can theories of modernity explain changed teaching conditions at Swedish music and culture schools?2009Inngår i: The Sixth International Conference for Research in Music Education: Summary Papers & Abstracts, 2009, s. 57-59Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This project investigates how teachers in the Swedish Music and Culture school are positioning themselves, how they construct their students and the teaching conditions. In this paper I will present the preliminary results of group conversations with teachers from six schools and discuss the findings in relation to theories of modernity. All together 27 teachers in music (instrumental teaching), drama, media (photo and film), dance and art were participating. On empirical level three different themes concerning teachers’ talk about changed attitudes among students are found, which have implications for teaching strategies. In the first theme, The Change, the teachers’ descriptions explain how the change of attitudes among the students have had an impact on teaching methods. Here, teaching “like before” is expressed as something impossible because “the students of today are different”. In the second theme, The Frustration, the teachers articulate a frustration about why the students do not behave like before. Here, the teachers talk about a change among the students, but they have not changed their teaching methods. Instead they express a frustration concerning the changed conditions. In the third theme, The Wish, the teachers also talk about a change. In doing this, stories about what could be different in teaching are discussed. These results express a discursive fracture concerning the performance of teachers’ profession all related to the different behaviour of the students. In the discussion of the findings in relation to theories of modernity concepts like detraditionalization, esthetization of everyday life and mass consumption are used in an attempt to explain why this breakage in the Swedish Music and Culture schools has taken place.

    What can discourse psychology say about teachers’ music talk and their teaching strategies?2009Inngår i: Proceedings of the 7th Triennial Conference of European Society for the Cognitive Sciences of Music (ESCOM 2009) Jyväskylä, Finland / [ed] Jukka Louhivuori, Tuomas Eerola, Suvi Saarikallio, Tommi Himberg & Päivi-Sisko Eerola, European Society for the Cognitive Sciences of Music , 2009, s. 187-192Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The teaching in music and culture schools is an activity that involves approximately one third of the children in Sweden, but there are only a few scientific studies conducted on the subject. The most of its participants will have music as a hobby in their future lives, but the vast majority of the students in higher music education once started their carriers in those schools. In this way music and culture schools can be seen as having a great impact on both cultural and musical activities in Sweden. This also points at the importance of knowledge concerning this institution, which this paper hopefully supplies for. The study has a social constructionist and post-structuralistic approach where both discursive psychology and discourse theory are used in the analysis of the data. The empirical material consists of group conversations with teachers in the music and culture school. The results are presented as two discourses. In The Teacher Tradition the teachers are passing on a tradition to the pupils. Here is a tendency to describe music as high and low. In The Pupil Preference the music taste of the pupils is regarded as essential and the task of teachers is to support their pupils. Here a relativistic approach to music is found where the pupils music taste determine the content of the teaching.

    The discourse psychological approach used in this study contribute to a relativistic and praxical understanding of teachers strategies, knowledge and identity constructions.

    Learning “theory and methodology of science” in professional education – a case study2017Inngår i: INTED2017 Proceedings: 11th International Technology, Education and Development Conference: March 6th-8th, 2017 — Valencia, Spain: Conference Proceedings / [ed] L. Gómez Chova, A. López Martínez & I. Candel Torres, IATED , 2017, s. 6924-6929Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The aim of the project is to study students’ learning in a transformed course in Theory and Methodology of Science (TMS), a compulsory course in all teacher education programs in Sweden.

    The students perceive the course TMS as difficult and abstract. At the same time it offers an important foundation for their continued education such as their final thesis and other research-related courses. Hereby it’s important for students to successfully pass, not only for the course itself, but also for subsequent courses. In a wider perspective, it is also sigificant for the development of the educational field, and to the students’ future workplaces. Our students should be able to understand and apply research for years to come. Heavy courses can also be problematic for economic reasons. Since few students are passing, they do not generate as much money as courses that many students pass. There are also examples where teachers are asked by the management to lower the requirements to increase the pass rate.

    As teachers we have put a lot of effort into the course to support and help students learning. Despite this, only 35% passed the exam in spring 2016, which gave rise to the learning experiment we designed and studied this fall. The pedagogical idea is based on a problem-oriented learning, participatory learning and self-organized learning. This means that the students themselves are largely responsible for the organization of their learning. Teachers work with lectures and seminars, as well as coaching and scaffolding. The course is designed as an authentic empirical research project where both quantitative and qualitative data is used as a starting point. Students work in teams. They organize their work in the project by them selves and write a common research rapport. Through the reformed course, learning is combined with a great student responsibility, where students meaning making, socialization and co-learning are central. Hence, the most important research group work takes place is the project-office-rooms where the students’ main course work is performed. The organization of the course involves that students themselves designates project managers and that they take responsibility for their joint work, week by week. They can also request extra support from the teachers, if necessary.

    The result of the study shows that 86% of the students received a passing grade. The aspects that matter most to the success are: 1) common spaces, the project office, which creates opportunities to exchange knowledge and experience IRL, 2) problem-oriented learning, participatory learning and self-organized learning, increasing participation and motivation, 3) Collective responsibility for knowledge formation during the project period, and 4) Authentic approach of the course, which by its design as closely as possible should simulate real research projects.

    Seen but not heard?! Children's participation in research about digital technology in preschool2017Inngår i: 27th EECERA Annual Conference: Social Justice, Solidarity and Children’s Rights’, Bologna, Italy, 29th August – 1st September 2017: Abstract Book, 2017, s. 45-45Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The aim of this study is to investigate norms and constructions of children in previous research concerning preschool children and digital technology. Digital technology is an important part of preschool activities. The number of children and preschool teachers who have access to computer tablets and clever boards in their everyday practice has increased in recent years (e.g. Couse & Chen, 2010, Edwards, 2013). This development has led to the need of extended knowledge concerning the critical contextual factors of digital technology use in preschool context (e.g. Lindahl & Folkesson, 2012). In the analysis of the material, social constructionism and discursive psychology (Wheterell & Potter, 1992, Potter, 1996) were used. This paper is based on a critical integrative literature review (Torraco, 2005) regarding research on preschool children and digital technology. The review draws from a number of scholarly research articles conducted between 2000-2015. Ethical considerations were met by showing respect and responsiveness to other researchers work (e.g. codex.vr.se). Preliminary results indicate that children often are marginalised in research and focus is more likely to be on an adult's point of view (such as the teacher or the parent). In this sense, children have a weak "voice" in research regarding digital technology use in preschool, therefore, the lack of the child's perspective is evident. The results, we argue, have important implications for researchers, preschool teachers and teacher educators in further discussions of how, when and for what purposes digital technology should be used in preschool children's activities.

    Abstract [en]

    The aim of this article is to discuss and problematize how teachers in civics in upper secondary school construct drama, and how it relates to teaching, and students’ knowledge formation in civics. A study like this is important as the aesthetic subjects are becoming more prominent in young people’s everyday life at the same time as school by recent reformations is increasing the adjustment to efficiency and measurability. The theoretical framework is built on discursive psychology, which emanates from social constructionist and poststructuralist theory. Data consists of interviews with four upper secondary teachers in civics. Findings show that drama can be a valuable resource for teaching and learning civics, but also a problem when it comes to assessment. The position of the student as an object, teaching as entertainment and the domination of text is also discussed and problematized. Findings are considered as problematic as drama in civics, in relation to assessment, rather enhances a text-focused three-subject school than offering an alternative challenge

    From a student perspective, what constitutes a good (or less good) use of ICT in teaching?2018Inngår i: Education and Information Technologies: Official Journal of the IFIP technical committee on Education, ISSN 1360-2357, E-ISSN 1573-7608Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper investigates what upper secondary school students regard as goodor less good teaching using ICT. 367 Swedish upper secondary students in 2 schoolsresponded to a web-based questionnaire. The students were asked to describe one oftheir teachers who used ‘ICT in a way that made them learn very well, and one whoused ICT in a way that made them learn less well’ and to describe what these teachersdid and why their teaching was understood as good or less good. 18 themes wereidentified, of which 17 were combined into eight overall counterpart themes and onenon-counterpart theme. ‘Clarity’ was the most prominent theme, followed by ‘teachers’‘ICT skills’, ‘uses ICT in a good way’, ‘fun factor’, ‘puts information on the LMS’,‘varies the teaching methods’, ‘demonstrates how to use ICT’ and ‘general pedagogicalskills’. The results show that although the specific focus is on students’ views of theirteachers’ use of ICT, general pedagogical skills are a major focus in the themes.Effectiveness is an explicit theme in terms of ICT adding value to teaching andlearning, while ineffectiveness is an implicit underlying dimension in the themesrelating to less good teaching. It is also evident that the students value the sameteacher’s use of ICT in teaching differently.

    The Nordic countries in the green transition – more than just neighbours: Strategic recommendations for Nordic co-operation on the environment and climate in the run-up to 20302018Annet (Annet (populærvitenskap, debatt, mm))
    Abstract [en]

    The Nordic countries have been working together for several decades to protect nature and the environment. This report presents the recommendations that have emerged from an external strategic review of the potential for official Nordic co-operation on the environment and climate under the auspices of the Nordic Council of Ministers for the Environment and Climate. The recommendations relate to the following five main areas: specific solutions for a green transition, mobilising key players, funding green transition, international co-operation, and adaptation to climate change.

    This report is part of a series of strategic and prospective studies commissioned by the Nordic Council of Ministers. Previous strategic reviews have dealt with working life, health and energy. The strategic reviews are part of the Nordic Council of Ministers’ reform programme.

    De nordiske lande i den grønne omstilling – mere end naboer: Strategiske anbefalinger for det nordiske miljø- og klimasamarbejde frem mod 20302018Annet (Annet (populærvitenskap, debatt, mm))
    Abstract [da]

    De nordiske lande har gennem flere årtier samarbejdet om miljø- og naturbeskyttelse i Norden såvel som internationalt. Denne rapport fremlægger anbefalingerne fra en ekstern strategisk undersøgelse af det fremtidige potentiale for det officielle nordiske miljø- og klimasamarbejde inden for rammerne af Nordisk Ministerråd for Miljø og Klima. Anbefalingerne peger på muligheder for, hvordan samarbejdet kan udvikle sig som en endnu mere relevant og konkret drivkraft for den grønne omstilling. Anbefalinger knytter sig til fem overordnede områder, hvor det nordiske miljø- og klimasamarbejde bør gøre sig tydeligt gældende: konkrete løsninger til grøn omstilling, mobilisering af nøgleaktører, finansiering af grøn omstilling, internationalt samarbejde og tilpasning til de klimamæssige ændringer.

    Att äta är en fråga om tajmning: klinisk översikt2010Inngår i: Läkartidningen, ISSN 0023-7205, E-ISSN 1652-7518, Vol. 107, nr 36, s. 2084-2095Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [sv]

    Dygnsrytm, hunger, törst, mättnad, temperatur, sexlust, blodsockermobilisering, substratutnyttjande och energiomsättning styrs från kärnor i hypotalamus.

    Dygnsrytmen styr beteende och fysiologiska processer till rätt tidpunkt för att hushålla med kroppens resurser. Vävnader och organ ska inte belastas kontinuerligt eller oväntat.

    Nattätande och dagsömn desynkroniserar dygnsrytmen.

    Åldersförändringar i hypotalamus orsakar aptitbortfall, tidsdesorientering, uttorkning och sömnstörningar hos äldre, som kan behöva äta frekvent och ha kortare nattfasta.

    Dygns- och måltidsrytmen bör utredas vid metabola störningar och fetma.

    Vid anorexi, bulimi, typ 2-diabetes, sängvätning och senil demens bör dygnsrytmens prestanda utredas – testa kronoterapi.

    Magnetic Nanoparticle Based Biosensors for Pathogen Detection and Cancer Diagnostics2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    This thesis describes several magnetic nanoparticle (MNP)-based biosensing strategies which take advantage of different magnetic sensors, molecular tools and nanotechnologies. Proposed biosensors can be classified into three groups, i.e., immunoassay-based, molecular amplification-based, and nanoparticle assembly-based. The principal motivation is to develop and optimize biosensors for out-of-lab and point-of-care testing.

    Immunoassay-based biosensors described in this thesis employ antibodies as the bio-recognition element for the detection of bacteria cells/fragments or proteins. Two typical immunoassay formats, i.e., direct and competitive format, are studied and compared for bacteria detection. In addition, in the protein biomarker detection, MNP chains are formed in the presence of target analytes as well as in the external rotating magnetic field. The high shape/magnetic anisotropy of the chains provides better optomagnetic performance.

    Two different molecular amplification methods, i.e., rolling circle amplification (RCA) and loop-mediated isothermal amplification (LAMP), are described under the topic of molecular amplification-based biosensors. In RCA-based biosensors, DNA probe modified MNPs bind to the amplicons after amplification. In LAMP-based biosensors, MNPs are either modified with primers that keep growing during the amplification, or are co-precipitated with the by-product (Mg2P2O7) of the amplification.

    The design of the nanoparticle assembly-based biosensors described in this thesis is based on duplex-specific nuclease (DSN)-assisted target recycling and core-satellite magnetic superstructures. In the presence of target microRNA, DSN cuts the DNA scaffold of the core-satellite assembly, releasing MNP satellites that can be quantified by the sensor.

    Different kinds of target analytes, i.e., pathogens or cancer biomarkers, are detected at the aiming for rapid, low-cost and user-friendly diagnostics.

    A Low Noise RC-based Phase Interpolator in 16-nm CMOS2018Inngår i: IEEE Transactions on Circuits and Systems - II - Express Briefs, ISSN 1549-7747, E-ISSN 1558-3791Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper describes a passive analog phase interpolator, utilizing a switched RC-network. The proposed circuit eliminates the current sources in a phase interpolator based on constant-slope charging. By eliminating the current source, the noise is significantly reduced due to the reduction in thermal and flicker noise. The phase interpolator has a resolution of 6 bits and is implemented in a 16-nm CMOS process. The maximum differential non-linearity is measured to be 0.1 LSBs at a 192 ps input time delta. The circuit draws 0.2 mW from a 0.8 V supply, and occupies 0.004 mm2.

    Unga vuxna, döden och ett förväntat liv2014Inngår i: Svensk kyrkotidning, ISSN 0346-2153, nr 2, s. 35-37Artikkel i tidsskrift (Annet vitenskapelig)
    Abstract [sv]

    I denna artikel av Caroline Gustavsson står unga vuxnas tankar kring döden i fokus. Hur unga vuxna ser på döden synliggör den gräns de ser för livet men tankar kring döden synliggör också vad de betraktar som ett förväntat liv. Efter en kort presentation av sitt avhandlingsarbete ger författaren några exempel på de unga vuxnas tal om döden och hur det går att tolka och förstå deras uttryck som en bild av vår tid där död, sjukdom och smärta betraktas som en långtifrån självklar aspekt av livet.
