    Green Liquor Dregs from Pulp and Paper Industry used in Mine Waste Management: a Symbiosis Project (GLAD) between two Swedish Base Industries2017In: Mine Water & Circular Economy / [ed] Wolkersdorfer, C., Sartz, L., Sillanpää, M. and Häkkinen, A, Lappeenranta, Finland: Lappeenranta University of Technology , 2017, Vol. II, p. 862-868Conference paper (Refereed)
    Abstract [en]

    Mining has been and still is an important industry in Sweden. Leaching from sulfidic mining waste is however a serious environmental issue that can bring acidity and metals in solution. Simultaneously, green liquor dreg (GLD) with potential to decrease oxygen transport to the waste and neutralize acid leachate, is generated by the pulp and paper industry and deposited in landfills. The aim of the project is to promote valorisation of GLD, identify hinders and create a database providing information about the material and its variability to enhance establishment of circular economy for the pulp and paper mill waste.

    Treatment of Historical Mining Waste using different Incineration Ashes2017In: Mine Water & Circular Economy / [ed] Wolkersdorfer, C., Sartz, L., Sillanpää, M. and Häkkinen, A, Lappeenranta, Finland: Lappeenranta University of Technology , 2017, Vol. II, p. 1125-1132Conference paper (Refereed)
    Abstract [en]

    ARD from historical mining sites in Sweden is a major source for trace elements to surface waters. In order to be able to treat a large portion of these sites cost effective reclamation methods is necessary. Incineration ashes were used in leaching tests to study their effect on a highly weathered mining waste in order to neutralize acidity and immobilize trace elements. This study shows that ashes can be used to increase pH and decrease trace element mobility from oxidized mining waste. Increased leaching of Cl, Mo and Sb, however, needs to be considered for waste fuel ashes before use.

    Mining Waste as an Exploration Tool and Secondary Resource2017In: Mine Water & Circular Economy / [ed] Wolkersdorfer, C., Sartz, L., Sillanpää, M. and Häkkinen, A, Lappeenranta, Finland: Lappeenranta University of Technology , 2017, Vol. II, p. 964-971Conference paper (Refereed)
    Abstract [en]

    There is today no overall information about how much mining waste there is in Sweden and what it contains. This project focused on samples from waste rock, tailings and slag from the historical mining region Bergslagen, Sweden. Modern dissolution and analytical methods were used in order to determine approximately 50 elements in the samples. Modern analytical data for the historical mining waste is useful as an exploration tool and can provide information about remaining or new resources underground. Results show that there is a potential for recovery of critical elements from mining waste as well as dealing with environmental problems.

    Understanding Groundwater Composition at Kvarntorp, Sweden, from Leaching Tests and Multivariate Statistics2017In: Mine Water & Circular Economy / [ed] Wolkersdorfer, C., Sartz, L., Sillanpää, M. and Häkkinen, A, Lappeenranta, Finland: Lappeenranta University of Technology , 2017, Vol. II, p. 770-776Conference paper (Refereed)
    Abstract [en]

    Due to oil production from alum shale, the Kvarntorp area is heavily polluted. A waste deposit consisting mostly of shale ash and fines is of important concern. Groundwater shows that parameters such as pH, U, V, Ni and Mo are different at different localities around the deposit. Leaching tests indicate that burned and unburned shale residues leave different signatures on leachates. Principal component analysis of groundwater and leaching tests suggest that ground-water is affected by the waste deposit and that it is more influenced by shale ash than by fines.

    Human Motion Prediction under Social Grouping Constraints2018In: 2018 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), IEEE, 2018, p. 3358-3364Conference paper (Refereed)
    Abstract [en]

    Accurate long-term prediction of human motion inpopulated spaces is an important but difficult task for mobile robots and intelligent vehicles. What makes this task challenging is that human motion is influenced by a large variety offactors including the person’s intention, the presence, attributes, actions, social relations and social norms of other surrounding agents, and the geometry and semantics of the environment. In this paper, we consider the problem of computing human motion predictions that account for such factors. We formulate the task as an MDP planning problem with stochastic policies and propose a weighted random walk algorithm in which each agent is locally influenced by social forces from other nearby agents. The novelty of this paper is that we incorporate social grouping information into the prediction process reflecting the soft formation constraints that groups typically impose to their members’ motion. We show that our method makes more accurate predictions than three state-of-the-art methods in terms of probabilistic and geometrical performance metrics.

    Eye-Tracking For Studying Mathematical Difficulties: Also In Inclusive Settings2018In: Proceedings of Annual Meeting of the International Group for the Psychology of Mathematics Education (PME-42), Umeå., Sweden: PME , 2018, Vol. 4, p. 115-122Conference paper (Refereed)
    Abstract [en]

    Eye-Tracking (ET) is a promising tool for mathematics education research. Interest is fue­led by recent theoretical and technical developments, and the potential to identify strategies students use in mathematical tasks. This makes ET in­teresting for studying students with mathematical difficulties (MD), also with a view on inclusive settings. We present a systematic analysis of the opportunities ET may hold for understanding strategies of students with MD. Based on an empirical study with 20 fifth graders (10 with MD), we illustrate that and why ET offers opportunities especially for students with MD and describe main advantages. We also identify limitations of think aloud protocols, using ET as validation method, and present characteristics of students’ strategies in tasks on quantity recognition in structured whole number representations.

    Vorgehensweisen bei der Anzahlerfassung am 100er Feld und 100er Rahmen: Eine Eye-Tracking Studie bei Kindern mit und ohne Rechenschwierigkeiten sowie sonderpädagogischem Unterstützungsbedarf2018In: Beiträge zum Mathematikunterricht 2018 / [ed] Fachgruppe Didaktik der Mathematik der Universität Paderborn, Münster, Germany: WTM Verlag, 2018, p. 1591-1594Conference paper (Refereed)
    Abstract [de]

    Arbeitsmittel werden im Mathematikunterricht zum Aufbau von Zahl- und Operationsvorstellungen genutzt. Gerade für Kinder mit Schwierigkeiten im strukturierten Erfassen von Anzahlen undunzureichenden Zahl- und Operationsvorstellungen ist die Nutzung von Darstellungen zentral. Wie gehenjedoch Kinder mit Rechenschwierigkeiten bei der Anzahlerfassung in unterschiedlichen Darstellungenvor und inwiefern erfolgt ein Transfer zwischen strukturell ähnlichen Darstellungen? Die vorgestellteStudie untersucht Vorgehensweisen bei der Anzahlerfassung am 100er Feld und 100er Rahmen bei 20Kindern (davon 11 mit Rechenschwierigkeiten und z.T. sonderpädagogischem Unterstützungsbedarf) zu Beginn der fünften Klasse. Eye-Tracking ermöglicht dabei neue Erkenntnisse gerade bei Kindern, die Schwierigkeiten haben, ihre Vorgehensweisen zu beschreiben. Die Ergebnisse liefern Einblicke in mathematische Kompetenzen und Schwierigkeiten der Kinder sowie die Unterschiede in der Nutzung derbeiden Darstellungen.

    Eye gaze technology to gain access to cognitive processes in individuals with profound intellectual and physical disabilities (PIPD)2018Conference paper (Other academic)
    Abstract [en]

    Objective: Individuals with profound intellectual and physical disabilities (PIPD) often cannot speak for themselves and do things for themselves. Their level of cognitive abilities is unclear. Eye gaze technology has the potential to gain access to cognitive processes and eventually enable communication among these individuals.

    Method: Six individuals with PIPD were given multiple sessions of eye gaze training (9-36 sessions) between February 17 to October 18. They used a screen eye-tracker (Tobii pc eye-mini) to control the objects/icons on the screen. An eye-gaze training program with different levels of activities was used to teach cause and effect, give appropriate response, explore the whole screen, target specific objects, choosing objects AND turn taking.

    Method and Theory in Their Interplay: Using Eye-Tracking for Investigating Mathematical Learning2018In: Dialogue between ontology and epistemology: New perspectives on theory and methodology in research on learning and education, 2018Conference paper (Refereed)
    Abstract [en]

    In this presentation, we discuss the interplay between theory and one particular method of data collection: eye-tracking. Eye-tracking promises various opportunities for research, in particular for studying students’ attention, strategies, and even collaboration in so-called dual eye-tracking (DUET), and has gained increased interest as a research method. Still, researchers acknowledge that eye-tracking data interpretation is difficult and ambiguous and often needs to be complemented with other sources. In this talk, we discuss two studies in which we aimed for a triangulation of eye-tracking with other research methods. In both studies, ontological and epistemological questions are intertwined.

    Abstract [en]

    This work investigates how agents can spatially orient themselves into formations which provide good conditions for enabling social interaction. To achieve this, we are using socio-psychological notion, F-formation in our project and based on this concept, we detect positions of other agents in a scene to find the optimum placement. Using both simulation and real robotic systems, the system aims to achieve a functionality which enables an agent to autonomously place itself within a group.

    Robotics for Successful Ageing2018In: Successful ageing in an interdisciplinary context: popular science presentations / [ed] Eleonor Kristoffersson & Kerstin Nilsson, Örebro, Sweden: Örebro University , 2018, p. 29-35Chapter in book (Other (popular science, discussion, etc.))
    Abstract [en]

    The main idea of the ongoing research is to use robotics to create new opportunities to help older people to remain alone in their apartments which can beachieved by using robots as an interacting tool between the elderly and theirfamily members or doctors. This can be done by building a system (software)for Mobile Robots to work autonomously (self-driving) and semi-autono-mously (controlled by the user) when necessary, depending on the situationand the surroundings. This system is integrated with social cues, particularlyproxemics, to know and understand human space, which is very importantfor social interaction. In conclusion, we are interested in having a Socially Intelligent Robot, which could use the social cues, proxemics, to have a natural interaction with people in groups.

    Grundskolebetyg under tre betygssystem: Fördelning på betygssteg och genomsnittliga ämnesbetyg 1990-20172019Report (Other academic)
    Abstract [sv]

    I rapporten beskrivs, med hjälp av SCB:s betygsstatistik, betygsutfallet för årskurs 9 åren 1990-2017, då tre olika betygssystem varit i bruk (2013-17 ingår även årskurs 6). Tonvikten ligger på att åskådliggöra hur elevernas prestationer i olika ämnen fördelas på de betygssteg som används vid olika tidpunkter. Därigenom synliggörs också hur betygssystemens skilda logiker och språk har betydelse för särskilt de elever som presenterar svagast. Systemen som sådana jämförs således inte, utan enbart hur betygssystemen fördelar alla elevprestationer i åk 9 under 28 års tid. En analys av de politiska ambitionerna bakom olika betygsreformer – vilka problem de ska lösa – ramar in rapporten. En av de mest framträdande slutsatserna är att införandet av ett målrelaterat betygssystem på 1990-talet, med skarp gräns för godkänt, omgående – i kontrast till förväntningarna – medför att en märkbar och över tid påtagligt stabil andel grundskoleelever inte når upp till den godkända nivån. Bytet till en ny skala på 2010-talet innebär härvidlag ingen förändring, vilket också är i linje med den politiska avsikten att låta gränsen för godkänt ligga fast. Under de målrelaterade systemen syns i många ämnen samtidigt en kontinuerlig ökning av andelen elever som får de högsta betygen. De sista åren med ett relativt betygssystem (1990-97) uppvisar, i linje med det systemets logik, en större stabilitet i fördelningen. Vissa ämnesskillnader finns dock under alla tre betygssystemen.

    Metals in pine needles: characterisation of bio-indicators depending on species2018In: International Journal of Environmental Science and Technology, ISSN 1735-1472, E-ISSN 1735-2630Article in journal (Refereed)
    Abstract [en]

    Air pollution can be studied by appropriate bio-indicators, such as pine needles due to their waxy surface. Metal uptake and accumulation is determined by on growing area, but also on the respective species. Scope of the study was to analyse needles of Pinus densiflora Siebold et Zucc., Pinus nigra Arnold, Pinus sylvestris L., and Pinus thunbergiana Franco for metals and metalloids, namely Aluminum, Arsenic, Boron, Barium, Calcium, Cadmium, Cobalt, Copper, Chromium, Iron, Potassium, Lithium, Magnesium, Manganese, Molybdenum, Sodium, Nickel, Lead, Selenium, Strontium, and Zinc. Quantitation of the analytes was performed using inductively coupled plasma atomic emission spectrometry and inductively coupled plasma sector field mass spectrometry after acidic microwave-assisted digestion.

    The obtained data were checked for statistically significant differences. The metal levels differ between the various species, but no general tendency was found for all metals. Since the environmental conditions were the same for all sampled trees, the differences in metal accumulation are supposed to be linked to species of pine tree.

    The diverse accumulation behaviour can be used for treating polluted soil.

    Mineral Composition of Elements in Walnuts and Walnut Oils2018In: International Journal of Environmental Research and Public Health, ISSN 1661-7827, E-ISSN 1660-4601, Vol. 15, no 12, article id 2674Article in journal (Refereed)
    Abstract [en]

    Walnuts (Juglans nigra) are considered to be a functional food. In the present study, twenty one macro-, micro-, and trace elements (Al, As, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, Pb, Se, Sr, and Zn) were selected to be determined in walnuts and walnut oils. The beneficial content of essential elements could be shown by the obtained results, the macro-elements Ca, K, Mg, and Na being present in nuts with 1062 mg/kg, 2771 mg/kg, 1426 mg/kg, and 42.3 mg/kg, respectively. Regarding micro- and trace elements, the following order (decreasing content) was found: Mn > Fe > Zn > B, Mo > Cu > Ni > Co > Al > Sr > Ba > Li > Pb > Se > Cr > As > Cd. Furthermore, the potentially toxic trace elements (As, Cd, Pb) determined were below the maximum allowed values in most of the investigated walnut samples. A comparison of oils and nuts revealed that the former contain lower concentrations of all elements analyzed except for Fe and Zn. This suggested the origin from contamination during oil processing. Fe influences the oil oxidation rate, thus its entry during production should be avoided.

    Improving Localisation Accuracy using Submaps in warehouses2018Conference paper (Other academic)
    Abstract [en]

    This paper presents a method for localisation in hybrid metric-topological maps built using only local information that is, only measurements that were captured by the robot when it was in a nearby location. The motivation is that observations are typically range and viewpoint dependent and that a map a discrete map representation might not be able to explain the full structure within a voxel. The localisation system uses a method to select submap based on how frequently and where from each submap was updated. This allow the system to select the most descriptive submap, thereby improving the localisation and increasing performance by up to 40%.

    The ‘Beauty’ of PISA: the Politics of How PISA Scores Are Used to Represent Public Education2018In: AERA 2018 Annual Meeting, AERA , 2018Conference paper (Refereed)
    Abstract [en]

    This paper concerns how expectations on public education are framed in policy discourse, and especially its pictorial representation of OECD’s PISA scores. Respectively 400 images in eight high scoring countries and eight low-performing countries are compared. Some clear differences appear. Strikingly PISA is mainly represented by statistical graphs. But we can also see that there is a tendency towards more pictures of children in PISA-successful countries. In low-performing there are instead a lot of pictures of concerned adults. One country, Sweden, that for long severed from a so-called PISA shock is then further analysed and the origin, as well as the reproduction of these images are traced. The overall purpose of the article is to contribute a new perspective on how representations of education can be gathered and analysed, by focusing on the politics of graphical representations of PISA scores. It is argued the there is an aesthetical dimension in the politics of PISA that frames our picture of education; that shows us what is important and what we should look at. There is also a political dimension in the aesthetics of PISA representations that moves our senses and emotions concerning education – i.e. how to feel about it.

    Designing a new training method for advanced hand prostheses2018In: Book of Abstracts, Ljubljana, Slovenia: ISPO Slovenia , 2018, p. 66-66Conference paper (Refereed)
    Abstract [en]

    INTRODUCTION: New prosthetic hands with advanced technology making it possible to perform many different grasps and positions are now available on the market. This new advanced technology is also difficult for users to control, and studies have shown that the new hand functions are not used to the extent expected (1).

    The Örebro Centre for Limb Deficiency and Arm Prostheses has a long experience of prosthetic fitting for both children and adults. About 80% of the adults report daily prosthesis use (2). Today, many prosthesis users find the advanced prosthetic hands interesting and wish to have one. However, when introducing a new prosthetic hand with questionable merits, the reasons for these results need to be considered. In light of our experience from fittings in Örebro, we decided that the training programs for the new hand models were not comprehensive enough, and there was a need for the development of a new method for training.

    AIMS: To design a training method for advanced hand prosthetic hands.

    METHODS: We performed a review of existing training programs for advanced myoelectric prosthetic hands and combined this with a structured training program, and a treatment philosophy with early fitting and regular follow up used in Örebro.

    RESULTS AND CONCLUSIONS: The training method comprises control training and performance of ADL’s. It follows a structured program based on the 14 steps described in the Skills Index Ranking Scale. The control training focuses on control of all different grasps available with the body in different positions: sitting, standing; with and without support of the arm. The ADL’s are chosen individually through a Canadian Occupational Performance Measure interview. The capacity to use different grasps and integrating the new prosthesis when performing ADL’s is evaluated through the Assessment of Capacity for Myoelectric Control. The method is based on regular support and feedback from an occupational therapist, with follow-ups weekly the first month and then monthly the following 3-6 months. The method has been used on patients with good results.

    CONCLUSION: A new method is designed to fit the new multifunctional prosthetic hands. The method can be applied upon prescription of advanced multifunctional prosthetic hands to enhance the functional use of the hands.

    Hållbarhet till middag: En etnologisk studie om hur miljövänligt ätande praktiseras i vardagslivet2016Doctoral thesis, monograph (Other academic)
    Abstract [en]

    Sustainability has become a conspicuous term in the public and political debate, as well as in the landscapes of consumption. This study focuses on how people understand and practice sustainability through food in their everyday life. The aim is to describe and analyse sustainability as a collection of meaning-making practices by studying households that in some sense actively aim for an environmentally friendly and sustainable food consumption. The ethnographic fieldwork, mainly interviews and participant observations, included fifteen households in a municipality in northern Sweden during 2012-15. The dissertation centres around reoccurring themes: organic food, local food, food as culture and materiality, morality and distinction. Through these themes it became evident that the participants related sustainable food practices to more than environmental issues. Socioeconomic relations within the locality and the global world, as well as cultural norms, traditions and values related to food, were important aspects of a perceived sustainable society. Although occasionally seeming inconsistent and contradictory in their meaning-making of and commitment to practices revolving around ideals of (ecological) sustainability, the participants balanced multiple sustainabilities simultaneously. Besides the ecological aspect, they also wished for sustainable localities, household economy, social relations and personal wellbeing.

    Influenced by social practice theory the study pays attention to the competences, meanings and materials a practice is dependent on. The participants developed individual repertoires, or practice bundles, of sustainable food related practices that were meaningful in their everyday life. The development and expansion of such a bundle could be understood as a form of acquiring and maintaining green capital; a symbolic capital based upon shared green values which unite the possessors and distinguish them from those lacking such values. Green capital is expressed through green distinction, that is, using taste to differentiate between holders and non-holders of the symbolic capital. The participants separated themselves from both the large majority who did not yet understand or practise sustainability, and from “fanatics” who they perceived took sustainability in an extreme and unsound manner. A balanced approach to sustainability was favoured as the participants to a great extent valued a lifestyle adjustable to the preconditions of the contemporary Swedish society, such as social norms. The study shows how sustainability is constantly renegotiated and filled with new cultural meaning.

    Managing Multiplicity: On Control, Care and the Individual2015Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This is a thesis about managing multiplicity. It analyses how people working in municipalities are managing, controlling, and caring for the complex and contradictory world they live in. Building on more than 100 interviews and observations, the thesis examines the multiple realities of those who work in public sector organisations. By studying (1) the work of managers on different organisational levels, controllers, professionals responsible for the care of others and, to a lesser extent, politicians; (2) the management control systems that are used in the work, and (3) the ongoing debates and legislations directed towards the management of care practices, the thesis makes an effort to analyse how the realities of these individuals; those active in controlling and caring, are constructed.

    The thesis makes several contributions to the literatures on management control and public management. Where earlier studies are either based on a functionalist conception of management control and public management (in which performance measures and control systems are tools in the hands of managers, that enable them to control other practices), or focused on understanding how control contributes to the construction of reality (making reality ontologically coherent, and therefore controllable), the present thesis argues that management can be approached and analysed as a practice devoted to managing ontological multiplicity, rather than as an activity devoted to control other practices or making reality controllable.

    By using the concept of ontological politics, the thesis shows that control often fails to make reality controllable, which makes the practice of management reliant on alternative ways to manage. The alternative to control that is analysed in the thesis is care, and the thesis argues that care could be seen as a way to manage, rather than as something that should be controlled: care is complementary to control when it comes to management. The thesis explicates how management by care is done in relation to management by control, and how they may become resources for each other in managing the complex and contradictory public sector.

    Ambivalence in environmental representation: A theoretical contribution2018In: Sociologisk forskning, ISSN 0038-0342, Vol. 55, no 4, p. 447-465Article in journal (Refereed)
    Abstract [en]

    In this paper, we examine the phenomenon of representation through the theoretical lens of ambivalence, concentrating on the people involved in representation: representatives. We argue that the theoretical concept of ambivalence can be helpful in analysing and understanding the various tensions environmental and other representatives encounter in their practice. Based on the concepts of “sociological ambivalence”, “ideological dilemma”, and “the organizational centaur”, as well as on insights from social studies of science and sustainability studies, the paper develops a typology of three potential sources of ambivalence: role conflicts, value conflicts, and conflicts between goals and means. In addition, the paper identifies various ways of coping with ambivalence, including the construction of meta-norms, organizational and network support, pragmatism, drawing boundaries for reasonable and acceptable actions, rule bending and discursive negotiation. The paper concludes that the concept of ambivalence adds crucial insights to the positions, practices, and challenges of environmental representatives and notes that ambivalence is not only a matter of tensions and conflicts but can be a source of reflexivity, learning, and agency.

    Intresserande samverkan: Från samsyn till framsyn – en studie inom Trafikverket2017Report (Refereed)
    Abstract [sv]

    Denna rapport har som mål att studera hur Trafikverket praktiserar strategi tillsammans med andra intressenter och aktörer. Rapporten utgör delprojekt 3 i ett större treårigt projekt som genomförts inom Akademin för ekonomistyrning i staten (AES) vid Företagsekonomiska institutionen, Stockholms universitet. Projektet har finansierats av Trafikverket, inom ramen för FoI-portfölj nummer sex, Trafikverket – en modern myndighet. Tidigare delrapporter inom projektet har visat att det internt i organisationen finns flera bilder av hur strategin ska omsättas i praktiken, samt diskuterat vad som är viktigt i detta arbete. Då en stor del av Trafikverkets uppdrag genomförs av externa parter ingår det också i forskningsprojektet att studera vad som händer med Trafikverkets strategiska arbete i externa relationer. När flera organisationers strategier möts, påverkar och påverkas av varandra väcks frågor om hur strategier samverkar och hur sådan strategisk samverkan fungerar i praktiken. Målet med denna rapport är därför att utveckla kunskap om strategisk verksamhetsstyrning genom att koppla samman frågor om strategi med frågor om samverkan. Detta uppnås genom att studera hur samverkan fungerar i praktiken. Som grund för rapporten har tre olika exempel på praktiker studerats där Trafikverket möter andra aktörer i planering och genomförande av Trafikverkets arbete.

    För att utveckla förståelsen av samverkan antar studien ett samverkansperspektiv: studien tar utgångspunkt i praktiken, snarare än i de samverkande aktörerna. Till skillnad från tidigare samverkansstudiers fokus på enskilda organisationers nytta av att samverka, innebär detta samverkansperspektiv fördjupade frågor om hur olika aktörer med olika intressen verkar samman, och hur sådan samverkan fungerar i praktiken. För att kunna diskutera samverkan på ett konstruktivt sätt används tre teoretiska begrepp i rapporten: mångfald, intressering och löften. Med dessa begrepp som utgångspunkt inriktas analysen på att undersöka förutsättningar för samverkan. Utifrån analysen av samverkans förutsättningar presenteras i rapportens avslutande kapitel ett utvecklat förhållningssätt till samverkan: intresserande samverkan.

    Digitalized national tests in mathematics: a way of increasing and securing equity?2019In: PROCEEDINGS OF THE TENTH INTERNATIONAL MATHEMATICS EDUCATION AND SOCIETY CONFERENCE: Hyderabad, India January 28th to February 2nd, 2019 / [ed] Jayasree Subramanian, Hyderabad, India, 2019Conference paper (Refereed)
    Abstract [en]

    On one hand, the Swedish governing discourse on equity in the context of digitizing education portrays modernization, progress and democracy as a foundation in the equity work. On the other hand, in the context of digitized tests, equity is rather framed within a neoliberal logic while related to all individuals’ possibilities of choosing a ‘good life’, and to compete on equal terms. Not all disadvantaged groups are the target, though. It is mainly boys who are supposed be given better grades, and, in addition, students with disabilities who are supposed to (as far as possible) be able to have the opportunity to show their knowledge during the test. Language or socioeconomically diverse settings are not mentioned with regard to digitized national tests.

    Offshoring of Services and Corruption: Do Firms Escape Corrupt Countries?2011Report (Other academic)
    Abstract [en]

    In this paper, we analyze how the offshoring of services by Swedish firms is affected by corruption in target economies. Taking stance from the gravity model of trade, we analyze how the choice of country, volume and composition of offshored services is affected by the presence of corruption in target economies. The results suggest that corruption is a deterrent for service offshoring. Firms avoid corrupt countries, and corruption reduces the amount of offshored services. In addition, the sensitivity to corruption is highest for poor countries, and large and internationalized firms are the ones that tend to be the most sensitive to corruption. Given the importance of large firms as international investors and subcontractors, this adds yet another argument for fighting corruption.

    Celiac disease and Infections2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Background: Celiac disease (CD) is a chronic immune-mediated enteropathy affecting about 1% of the population worldwide. CD is triggered by ingestion of gluten in genetically predisposed individuals but additional factors (e.g. infections) are required for the disease to develop. CD also seems to be associated with infectious complications.

    Aim: The main objective of this thesis was to increase the knowledge about the associations between CD and infections.

    Methods: Epidemiological and laboratory approaches. Studies I-III used a data set consisting of small intestinal biopsy reports. The biopsies were taken in 1969-2008 and collected in 2006-2008. A total of 29,096 individuals with CD, 13,306 with inflammation and 3,719 with potential CD were identified. Each individual was matched with up to 5 controls from the general population (n= 228,632). Through linkage of the data to the Patient Register study I examined the risk of hospital visits due to respiratory syncytial virus (RSV) in children <2 years prior to onset of CD. Study II used the Patient Register and Cause of Death Register to assess whether CD affects the outcome in sepsis. Study III linked the data to microbiological data bases and the Public Health Agency to estimate risk of invasive pneumococcal disease (IPD) in CD. In study IV children with CD and controls were recruited from Kalmar County Hospital. Complement activation (C3a and sC5b-9) in plasma were analysed after incubation with pneumococci.

    Results: Study I found that children with CD were more likely than controls to have attended hospital due to RSV infection prior to diagnosis (odds ratio 1.46; 95% confidence interval (CI)=1.02-2.07). CD did not seem to influence survival in sepsis (adjusted hazard ratio (HR) 1.10 95%CI=0.72-1.69) (study II). Study III indicated a 46% risk increase for individuals with CD to acquire IPD (HR 1.46; 95%CI=1.05-2.03) but study IV did not reveal any differences in complement response in regard to CD status (p=0.497and p=0.724), explaining this excess risk.

    Conclusion: This thesis supports associations between CD and infections preceding and complicating diagnosis. However, CD does not seem to influence the outcome in a severe infection like sepsis and altered complement function is unlikely to be responsible for the excess IPD risk in CD.

    Abstract [en]

    Background and Aim: The purpose of this study was to examine the association between celiac disease (CD) and prior respiratory syncytial virus (RSV) infection or any viral bronchiolitis.

    Methods: This was a retrospective case–control study. During 2006–2008 small intestinal biopsy data were collected from Sweden’s 28 pathology departments. We identified 3,835 children diagnosed with CD (villous atrophy, Marsh stage 3) before the age of 2 years in 1987 or later. Using conditional logistic regression we calculated odds ratios (ORs) for having a prior diagnosis of respiratory syncytial virus or other viral bronchiolitis compared to 19,102 age- and sex-matched controls.

    Results: Of the 3,835 children with CD, 36 (0.9 %) had a prior diagnosis of RSV compared to 117/19,102 (0.6 %) matched controls. This corresponded to an OR of 1.46 (95 % CI 1.03–2.07). ORs were similar in girls and boys. The highest ORs were seen in children developing early CD (before 1 year of age (OR 1.82; 95 % CI 0.91–3.62). Prior record of any type of viral bronchiolitis was found in 3.4 % (132/3,835) of individuals with CD and in 2.0 % (390/19,102) of the matched controls corresponding to an OR of 1.60 (95 % CI 1.33–1.92).

    Conclusions: Children with CD diagnosed\2 years of age were more likely to have attended hospital for a prior RSV infection or any viral bronchiolitis than other children.

    Abstract [en]

    Background: Individuals with celiac disease (CD) are at increased risk of sepsis. The aim of this study was to examine whether CD influences survival in sepsis of bacterial origin.

    Methods: Nationwide longitudinal registry-based study. Through data on small intestinal biopsies from Sweden's 28 pathology departments, we identified 29,096 individuals with CD (villous atrophy, Marsh stage III). Each individual with CD was matched with five population-based controls. Among these, 5,470 had a record of sepsis according to the Swedish Patient Register (1,432 celiac individuals and 4,038 controls). Finally we retrieved data on mortality in sepsis patients through the Swedish Cause of Death Registry.

    Results: CD was associated with a 19% increase in overall mortality after sepsis (95% confidence interval (CI) = 1.09-1.29), with the highest relative risk occurring in children (adjusted hazard ratio (aHR) = 1.62; 95%CI = 0.67-3.91). However, aHR for death from sepsis was lower (aHR = 1.10) and failed to reach statistical significance (95%CI = 0.72-1.69). CD did not influence survival within 28 days after sepsis (aHR = 0.98; 95%CI = 0.80-1.19).

    Conclusions: Although individuals with CD seem to be at an increased risk of overall death after sepsis, that excess risk does not differ from the general excess mortality previously seen in celiac patients in Sweden. CD as such does not seem to influence short-term or sepsis-specific survival in individuals with sepsis and therefore is not an independent risk factor for poor prognosis in sepsis.

    Abstract [en]

    Severe infections are recognized complications of coeliac disease (CD). In the present study we aimed to examine whether individuals with CD are at increased risk of invasive pneumococcal disease (IPD). To do so, we performed a population-based cohort study including 29 012 individuals with biopsy-proven CD identified through biopsy reports from all pathology departments in Sweden. Each individual with CD was matched with up to five controls (n = 144 257). IPD events were identified through regional and national microbiological databases, including the National Surveillance System for Infectious Diseases. We used Cox regression analyses to estimate hazard ratios (HRs) for diagnosed IPD. A total of 207 individuals had a record of IPD whereas 45/29 012 had CD (0.15%) and 162/144 257 were controls (0.11%). This corresponded to a 46% increased risk for IPD [HR 1.46, 95% confidence interval (CI) 1.05-2.03]. The risk estimate was similar after adjustment for socioeconomic status, educational level and comorbidities, but then failed to attain statistical significance (adjusted HR 1.40, 95% CI 0.99-1.97). Nonetheless, our study shows a trend towards an increased risk for IPD in CD patients. The findings support results seen in earlier research and taking that into consideration individuals with CD may be considered for pneumococcal vaccination.

    Integrated Solutions in the Capital Goods Sector: Exploring innovation, service and network perspectives2007Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    With varying degrees of success, a number of firms in the capital goods sector are experimenting with different ‘integrated solutions’ initiatives. Integrated solutions include product innovations which enable increased process control that allows the optimisation of the customers’ processes, as well as business innovations which change the firms’ business models and customer approach. It is not always easy to develop and commercialise these new offerings, especially for firms that have traditionally focused on developing and selling products. Integrated solutions challenge these firms to shift the focus from physical products, spare parts and support services to emphasis on delivery of performance optimisation and productivity.

    This thesis is a compilation of five papers and five supporting chapters that discuss and analyse the challenges with developing and commercialising integrated solutions in the capital goods sector. The research builds on case studies of firms experimenting with integrated-solution offerings. The firms produce complex, expensive industrial machinery to customers in the process and manufacturing industries. The main case is based on a five-year, in-depth longitudinal study of Alfa Laval, and more specifically of the developments within the wastewater industry. Other case studies include ITT Flygt and Atlas Copco.

    The thesis shows that the development and commercialisation of integrated solutions represent a multifaceted, iterative and complex process for the firms under study, who need to combine product, service and business innovations, create new business structures, and create new relationships with customers and possible partners. Consequently, the development of integrated solutions is not confined to or explained by one theoretical field in this thesis, but is linked to innovation, service and network perspectives.

    The thesis also shows that the three activities of innovating, organising and building relationships are dependent on changing market structures, customer demands and business cycles. Therefore it becomes important to manage the coexistence of different types of offerings, such as products, services and integrated solutions.

    The Treasurer's Guide to the Municipality: Essays on Sub-Sovereign Finance2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis presents a comprehensive empirical analysis of the current state of Swedish sub-sovereign finance from multiple perspectives, starting from the local and moving to the national. Financial risks may occur in a long line of financial obligations and transactions. Thus, for understanding the full scope of financial risks one perspective is not sufficient. From a societal perspective the question of sub-sovereign debt management is important since mismanagement may lead to substantial risks which may impact the lives of citizens by a weakening of the Swedish public programs. Sub-sovereign debt is mainly funded by issuing financial securities in both national and foreign capital markets. Understanding the market perception regarding the risk profile of Swedish sub-sovereigns may be beneficial in improving the funding conditions of the sector and in turn reduce the cost of public investments. Financial markets are however not stand-alone entities and are heavily impacted by the policy decisions of public institutions. Thus, monetary policy plays an important role in affecting financial markets and consequently the funding conditions of Swedish sub-sovereigns. Given the contemporary approach to monetary policy this effect may be somewhat different compared to what it has been historically. There are however reasons to suspect that the national policy decisions are in large part driven by international occurrences and by foreign governments through international spillovers. Thus, for understanding the interlinked nature of financial markets a wider perspective is needed. These are some of the areas which are investigated in this thesis.

    Abstract [en]

    This paper presents a comprehensive empirical analysis of the debt maturity structure of the Swedish municipal sector. The Swedish municipal debt portfolio is characterized by a short maturity structure and an asset-liability mismatch that poses potentially severe roll-over risk. The 2008–2009 financial crisis manifested as a liquidity shock to the sector that highlighted the dangers of short-term funding strategies in conjunction with low levels of intertemporal diversification. In this study we analyze to what extent this led to a change of intertemporal diversification. Based on a unique contract-level monthly data set of municipal loans issued by Kommuninvest of Sweden from January 1997 to June 2016, we construct and estimate a range of dispersion and moment measures to capture the change of various distributional characteristics of the maturity structure. These measures are used as dependent variables in fixed-effects models together with a number of control variables to estimate the effect of the debt-crisis liquidity shock. The main finding is that the crisis did affect the diversification, but not in a persistent way. A possible explanation is that the municipalities found that Kommuninvest through jointly guaranteed lending was able to function as a lender of last resort and thereby mitigates the roll-over risk. It is also found that fiscal and financial properties such as debt-to-tax base ratio, tax base volatility and per capita income are associated with the characteristics of the debt maturity structure of Swedish municipalities, as well as macroeconomic factors such as the term structure of interest rates.

    Developing and evaluating an interactive app to support self-care among older persons receiving home care2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The proportion of older persons worldwide is growing. With older age, complex health problems may occur and the need for home care increases. To support older persons to maintain health and self-care, innovative ways need to be developed. The aim of the project was to develop and evaluate an interactive app among older persons receiving home care. The project had several phases: i) to define and understand the problem ii) develop the intervention iii) develop and optimise evaluation. Qualitative and quantitative methods were employed. Data were collected through a scoping review, interviews with healthcare experts, older persons and nursing assistants (study I); interviews with older persons (studies II, III); focus groups with homecare nurses (study II). Questionnaires at baseline, end of intervention and 6-month follow-up; with instruments to assess aspects of health, health literacy, self-care, and a study specific question regarding sense of security were used (studies III-IV). Logged data from reported health concerns, alerts, and notes were collected (study IV). Data were analysed using qualitative content analysis (study I), thematic analysis (study II), qualitative content analysis with directed approach (study III) and descriptive and inferential statistics (studies III, IV). Results: Important aspects for health and self-care from the older persons’ perspectives were described as: frame of mind, having relationships and social activities, physical ability and concerns, and maintaining self-care (I). These results were included in the app as questions with self-care advice, graphs and alerts to homecare nurses. The app use was described as an enabler for learning (II). The older persons showed improved communicative and critical health literacy at the 6- month follow-up (IV). They described an increased sense of security (II and III), which decreased at the 6-month follow-up (III). They expressed increased self-confidence (II) and support in self-care, but reported a decrease in self-care ability at the 6-month follow-up (III). App usage was high, with the health concern pain triggering the most alerts (IV). Their aspects of health were unchanged at the three assessments points (IV). In this context using an app may increase older persons’ participation in their care. The results show that for some older persons, an app can be implemented as a tool for support in conventional home care.

    AIM AND OBJECTIVES: To acquire knowledge regarding the contents to be implemented in an interactive ICT-platform perceived to be relevant to health and self-care among older persons based on the literature, healthcare professionals and the older persons themselves.

    BACKGROUND: The growing ageing population places demands on the healthcare system to promote healthy ageing and to strengthen the older person's self-care ability. This requires innovative approaches to facilitate communication between the older person and healthcare professionals, and to increase the older person's participation in their care. An information and communication technology-platform (ICT-platform) could be used for this purpose, but the content needs to be relevant to both the older persons and the healthcare professionals.

    DESIGN: Descriptive qualitative design.

    METHODS: This study was based on three samplings: a scoping review of the literature (n=20 articles), interviews with healthcare professionals (n=5), and a secondary analysis of interviews with older persons (n=8) and nursing assistants (n=7). The data were analysed using qualitative content analysis.

    RESULTS: Four areas were identified to be of relevance to older persons' perceived health: frame of mind, having relationships and social activities, physical ability and concerns, and maintaining self-care. Self-care was described in the literature and by the healthcare professionals more than by the older persons.

    CONCLUSIONS: The results show a concordance in the data samplings that give a clear indication of the areas relevant to older persons' health and self-care that can be integrated in an interactive ICT-platform for use in regular daily care assessments. Descriptions of self-care was limited indicating a possible gap in knowledge that requires further research.

    RELEVANCE TO CLINICAL PRACTICE: Areas relevant to older persons' health and self-care could be used for regular assessment to support and promote healthy ageing.

    Abstract [en]

    AIMS AND OBJECTIVES: To explore the experiences of using an app among older people with home-based health care and their nurses.

    BACKGROUND: Few information and communication technology innovations have been developed and tested for older people with chronic conditions living at home with home-based health care support. Innovative ways to support older people's health and self-care are needed.

    DESIGN: Explorative qualitative design.

    METHODS: For 3 months to report health concerns, older people receiving home-based health care used an interactive app, which included direct access to self-care advice, graphs and a risk assessment model that sends alerts to nurses for rapid management. Interviews with older people (n = 17) and focus group discussions with home care nurses (n = 12) were conducted and analysed using thematic analysis.

    RESULTS: The findings reveal that a process occurs. Using the app, the older people participated in their care, and the app enabled learning and a new way of communication. The interaction gave a sense of security and increased self-confidence among older people. The home care nurses viewed the alerts as appropriate for the management of health concerns. However, all participants experienced challenges in using new technology and had suggestions for improvement.

    CONCLUSIONS: The use of an app appears to increase the older people's participation in their health care and offers them an opportunity to be an active partner in their care. The app as a new way to interact with home care nurses increased the feeling of security. The older people were motivated to learn to use the app and described potential use for it in the future.

    IMPLICATIONS FOR PRACTICE: The use of an app should be considered as a useful information and communication technology innovation that can improve communication and accessibility for older people with home-based health care.

    “This is my cheating ex”: Gender and sexuality in revenge porn2018In: Sexualities, ISSN 1363-4607, E-ISSN 1461-7382, p. 1-23Article in journal (Refereed)
    Abstract [en]

    Revenge pornography is the online, and at times offline, non-consensual distribution, or sharing, of explicit images by ex-partners, partners, others, or hackers seeking revenge or entertainment. In this article, we discursively analyse a selected range of electronic written texts accompanying explicit images posted by self-identified straight/gay/lesbian (male-to-female, female-to-male, male-to-male, female-to-female postings) on a popular revenge pornography website ‘MyEx.com’. Situating our analysis in debates on gender and sexuality, we examine commonalities and differences in the complex and sometimes contradictory ways in which gender and sexuality are invoked in posters’ accounts of their motivations for revenge pornography.

    University entrepreneurship education: A design thinking approach to learning2019In: Journal of Innovation and Entrepreneurship, ISSN 2192-5372, E-ISSN 2192-5372, Vol. 8, no 3, p. 1-11Article in journal (Refereed)
    Abstract [en]

    Background: Entrepreneurship has traditionally been taught from a business administration perspective, where predicting the future is central and where the world is seen as linear with known inputs and outputs. The world of entrepreneurs is a quite different, usually highly uncertain environment, and therefore requires a different type of skill set. In this paper, we conceptualize entrepreneurial learning through a method- and design-based approach and illustrate how a course can be developed and designed.

    Findings: In this paper it is argued that by utilizing design thinking and a methods approach, learning from a “through” approach can be achieved. This learning is more focused on the entrepreneurial process, highlighting the role of skills and mindset. This learning approach enables student-centered learning and focus on skills more applicable to entrepreneurs. It is also argued that the entrepreneurship process is not linear; therefore, creativity is central and finding structure is an unstructured process. Design thinking emphasizes a practical approach where students step outside the classroom. This experimentation and interaction in the real world of users and customers with real feedback is important in combination with reflection exercises.

    Conclusions: This paper highlights how a methods approach and entrepreneurship education with a “through” perspective can be achieved by utilizing design thinking. This is elaborated conceptually and illustrated with an example. We argue that a methods approach for teaching entrepreneurship is beneficial, where design thinking can be one valuable tool and approach for teaching entrepreneurship.

    Heart Rate Variability in Elite Synchronized Swimmers2018In: International Journal of Sports Physiology and Performance, ISSN 1555-0265, E-ISSN 1555-0273, p. 1-24Article in journal (Refereed)
    Abstract [en]

    PURPOSE: To determine whether heart rate variability (HRV) was correlated with other training load and training tolerance markers for monitoring the effect of a training session on elite synchronized swimmers.

    METHODS:: , SC, and RPE and relative changes (Δ%) in the natural logarithm of the root mean square successive difference of intervals (LnRMSSD). We also calculated the smallest worthwhile change (SWC) of the averaged pre and post LnRMSSD measurements.

    RESULTS:: (6.8±2.7) was correlated positively with Δ%LnRMSSD and Δ%SC.

    CONCLUSIONS:: , Δ%SC, and RPE indicated reduced sympathetic activation and positive adaptation to the stress imposed by the session. Isolated HRV assessment may reveal a controversial interpretation of the autonomic nervous system status or the training tolerance in elite SS athletes that are influenced by diving response.

    Bioelectrical impedance vector analysis (BIVA) for measuring the hydration status in young elite synchronized swimmers2017In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 12, no 6, article id e0178819Article in journal (Refereed)
    Abstract [en]

    PURPOSE: The assessment of body hydration is a complex process, and no measurement is valid for all situations. Bioelectrical impedance vector analysis (BIVA) has emerged as a relatively novel technique for assessing hydration status in sports. We applied BIVA a) to determine hydration changes evoked by an intense synchronized swimming (SS) training session; b) to characterize the sample of young elite swimmers in relation with a nonathletic reference population; and c) to generate its 50%, 75% and 95% percentiles of the bioelectrical variables.

    METHODS: Forty-nine elite SS female swimmers of two age categories, comen (Co: 13.9 ± 0.9 years, n = 34) and junior (Jr: 16.3 ± 0.6 years, n = 15), performed a long, high intensity training session. Body mass (BM) and bioelectrical variables (R, resistance; Xc, reactance; PA, phase angle; and Z, impedance module) were assessed pre- and post-training. BIVA was used to characterize 1) the distribution pattern of the bioelectrical vector (BIA vector) for both age groups, and 2) pre- to post-training BIA vector migration. Bioelectrical variables were also correlated with BM change values.

    RESULTS: Most swimmers were mostly located outside the 75% and some beyond the 95% percentile of the bioelectrical tolerance ellipses of the general population. The BIA vector showed statistically significant differences in both Co (T2 = 134.7, p = 0.0001) and Jr (T2 = 126.2, p < 0.001). Both groups were also bioelectrically different (T2 = 17.6, p < 0.001). After the training session, a decrease in BM (p = 0.0001) and an increase in BIA variables (p = 0.01) was observed. BIVA also showed a significant pre-post vector migration both in Co (T2 = 82.1; p < 0.001) and Jr (T2 = 41.8; p < 0.001). No correlations were observed between BM changes and bioelectrical variables.

    CONCLUSIONS: BIVA showed specific bioelectrical characteristics in young elite SS athletes. Considering the decrease in BM and the migration of the BIA vector, we conclude that the homeostatic hydration status of these young elite female swimmers was affected by the execution of intense training sessions. From a methodological perspective, BIVA appears to be sensitive enough to detect subtle hydration changes, but further research is needed to ensure its validity and reliability. Moreover, these findings highlight the importance of ensuring adequate fluid intake during training in young SS athletes.

    A Digital Society For All?: Meanings, Practices and Policies for Digital Diversity2019In: Proceedings of the 52nd Hawaii International Conference on System Sciences, 2019, p. 3067-3076Conference paper (Refereed)
    Abstract [en]

    The concept of digital divides has been on the agenda in research and policy making for at least the last 20 years. But it is still, a challenge to grasp this concept that is so elusive and transforming. Inclusion, access and equality are still key values for democratic governance and must be addressed in particular when forming and contributing to a digital government. This paper seeks to intervene in current debates on digital divides and digital inclusion by analyzing two cases of responses among street-level public administration in relation to e-government services in Sweden. The case studies are strategically chosen and conducted in national agencies and in local public libraries. Three lines of contributions are discussed, firstly the importance to care for equality secondly the need to see the non-users, and thirdly to discuss the potential of putting focus on digital diversity.

    Microplastics as Vehicles of Environmental PAHs to Marine Organisms: Combined Chemical and Physical Hazards to the Mediterranean Mussels, Mytilus galloprovincialis2018In: Frontiers in Marine Science, E-ISSN 2296-7745, Vol. 5, no Apr, article id 103Article in journal (Refereed)
    Abstract [en]

    The ubiquitous occurrence of microplastics (MPs) in the marine environment is raising concern for interactions with marine organisms. These particles efficiently adsorb persistent organic pollutants from surrounding environment and, due to the small size, they are easily available for ingestion at all trophic levels. Once ingested, MPs can induce mechanical damage, sub- lethal effects and various cellular responses, further modulated by possible release of adsorbed chemicals or additives. In this study, ecotoxicological effects of MPs and their interactions with benzo(a)pyrene (BaP), chosen as a model compound for polycyclic aromatic hydrocarbons (PAHs) were investigated in Mediterranean mussels, Mytilus galloprovincialis. Organisms were exposed for four weeks to 10 mg/L of low-density polyethylene (LD-PE) microparticles (2.34x107 particles/L, size range 20-25 µm), both virgin and pre-contaminated with BaP (15µg/g). Organisms were also exposed for comparison to BaP dosed alone at 150 ng/L, corresponding to the amount adsorbed on microplastics. Tissue localization of microplastics was histologically evaluated; chemical analyses and a wide battery of biomarkers covering molecular, biochemical and cellular levels allowed to evaluate BaP bioaccumulation, alterations of immune system, antioxidant defenses, onset of oxidative stress, peroxisomal proliferation, genotoxicity and neurotoxicity. Obtained data were elaborated within a quantitative weight of evidence (WOE) model which, using weighted criteria, provided synthetic hazard indices, for both chemical and cellular results, before their integration in a combined index. Microplastics were localized in haemolymph, gills and especially digestive tissues where a potential transfer of BaP from MPs was also observed. Significant alterations were measured on the immune system, while more limited effects occurred on the oxidative status, neurotoxicity and genotoxicity, with a different susceptibility of analyzed pathways, depending on tissue, time and typology of exposure. Molecular analyses confirmed the general lack of significant variations on transcriptional activity of antioxidant and stress genes. The overall results suggest that microplastics induce a slight cellular toxicity under short-term (28 days) exposure conditions. However, modulation of immune responses, along with bioaccumulation of BaP, pose the still unexplored risk that these particles, under conditions of more chronic exposure (months to years) or interacting with other stressors, may provoke long-term, subtle effects on organisms’ health status.

    Information privacy practices in eGovernment in an African Least Developing Country, Rwanda2019In: Electronic Journal of Information Systems in Developing Countries, ISSN 1681-4835, E-ISSN 1681-4835, Vol. 85, no 2, article id e12074Article in journal (Refereed)
    Abstract [en]

    Privacy of information is a critical issue for e-government development as lack of it negatively influences users’ trust and adoption of e-government. To earn user trust government organizations need to provide reliable privacy assurance by implementing adequate information privacy protection (IPP) practices. African Least Developing Countries (LDCs) today develop e-government but focus is on quick technical development and the status of IPP issues is not clear. Little research has yet studied the status of IPP practices in e-government in African LDCs. To fill this gap, we assess the status of existing IPP practices in e-government in Rwanda, using international privacy principles as an assessment baseline. We adopt a case-study approach including three cases. Data were collected by interviews and a survey. The findings call into question the efficacy of existing IPP practices and their effect in ensuring e-government service users’ privacy protection in Rwanda. The study extends existing literature by providing insights related to privacy protection from an African LDC context. For practitioners in Rwanda and other LDCs, this study contributes to the protection of information privacy in e-government by providing recommendations to mitigate identified gaps.

    The Untimely-Image: On Contours of the New in Political Film-Thinking2012Doctoral thesis, monograph (Other academic)
    Abstract [en]

    This study creates and develops a concept called the untimely-image including two sub-concepts called contours of the new and the untimely-site. The untimely-image concerns the clearing for and the expression of figures of “potential” in thought in the form of moving-images. The aim of these concepts is to form a critical framework for evaluating and conceptualizing political film as expressive, not of the new itself but of its “untimely” contours.

    The untimely-image, and its many implications, is developed over the course of six chapters. Chapter 1 extensively defines “contours” and “new” as operative in this study, and also introduces a theme that runs through all the chapters: how to think the contours of the new in relation to the cult of the new in consumer culture and in relation to the larger mechanisms of advanced capitalism. Chapter 2 defines the parameters of the untimely-image as specifically regarding moving images, and continues the development of this concept. In Chapters 3 to 6, The Wire (David Simon, 2002-2008) serves the double function of complicating and giving specification to the elaboration of the untimely-image as well as a case in which the untimely-image is used as a critical framework. The Wire and the untimely-image relate in processes of juxtaposition, wherein they meet, cross over, separate, and reproblematize each other. An untimely-image is fully defined in relation to concrete political issues. The untimely-image is therefore advanced by articulating the components and characteristics that, independently of the concrete issue, remain in every case, as well as by putting the concept to work regarding two specific problems in The Wire: its expression of blackness and its mapping of advanced capitalism.

    Erkekleri Feminizmin İçinde ve Dışında Çerçevelemek: [Framing ‘men in and not in feminism]2017In: Fe Dergi: Feminist Eleştiri, ISSN 1309-128X, Vol. 9, no 2, p. 85-101Article in journal (Refereed)
    Abstract [en]

    This article addresses some aspects of the “Man Question” in feminism, by way of the analysis ofmen’s diverse gender-conscious positionings in relation to gender, gender equality and feminism. Itbuilds on earlier work, making use of theoretical models in feminist literature combined with themicro-sociological concept of passing. Consideration is also given to men’s non-gender-consciouspositionings. The article is primarily concerned with the theoretical and empirical complexities,contradictions and ambiguities of men’s positionings, as when they are self-defined as “feminists” (orsimilar identifications) in radical or deconstructive ways. In this, a Swedish interview data is used.Sweden is considered particularly interesting, with a qualified societal consensus on gender equalityand a broadly positive place accorded to men’s relations with feminism. The authors argue in the finalsection that there is a need to further dialogue between analyses of men/masculinities and themultidimensionality of feminisms, as well as a need for more empirical studies of men’s different(pro)feminist positionings in order to elaborate the theoretical implications of different socialcontexts. The framing presented seeks to provide greater possibilities for such complex, nuanced andsituated understandings of men’s relation to feminism, theoretically, analytically and politically.

    Autotaxin-Lysophosphatidic Acid Signaling Contributed to Obesity-Induced Insulin Resistance in Muscle and Impairs Mitochondrial Metabolism2018In: Journal of Lipid Research, ISSN 0022-2275, E-ISSN 1539-7262, Vol. 59, no 10, p. 1805-1817Article in journal (Refereed)
    Abstract [en]

    Autotaxin (ATX) is an adipokine that generates the bioactive lipid, lysophosphatidic acid (LPA). ATX-LPA signaling has been implicated in diet-induced obesity and systemic insulin resistance. However, it remains unclear whether the ATX-LPA pathway influences insulin function and energy metabolism in target tissues, particularly skeletal muscle, the major site of insulin-stimulated glucose disposal. The objective of this study was to test whether the ATX-LPA pathway impacts tissue insulin signaling and mitochondrial metabolism in skeletal muscle during obesity. Male mice with heterozygous ATX deficiency (ATX +/-) were protected from obesity, systemic insulin resistance, and cardiomyocyte dysfunction following high-fat high-sucrose (HFHS) feeding. HFHS-fed ATX +/- mice also had improved insulin-stimulated AKT phosphorylation in white adipose tissue, liver, heart, and skeletal muscle. Preserved insulin-stimulated glucose transport in muscle from HFHS fed ATX +/- mice was associated with improved mitochondrial pyruvate oxidation in the absence of changes in fat oxidation and ectopic lipid accumulation. Similarly, incubation with LPA decreased insulin-stimulated AKT phosphorylation and mitochondrial energy metabolism in C2C12 myotubes at baseline and following palmitate-induced insulin resistance. Taken together, our results suggest that the ATX-LPA pathway contributes to obesity-induced insulin resistance in metabolically relevant tissues. Our data also suggest that LPA directly impairs skeletal muscle insulin signaling and mitochondrial function.

    Lysophosphatidic Acid Signaling in Obesity and Insulin Resistance2018In: Nutrients, ISSN 2072-6643, E-ISSN 2072-6643, Vol. 10, no 4, article id 399Article, review/survey (Refereed)
    Abstract [en]

    Although simple in structure, lysophosphatidic acid (LPA) is a potent bioactive lipid that profoundly influences cellular signaling and function upon binding to G protein-coupled receptors (LPA1-6). The majority of circulating LPA is produced by the secreted enzyme autotaxin (ATX). Alterations in LPA signaling, in conjunction with changes in autotaxin (ATX) expression and activity, have been implicated in metabolic and inflammatory disorders including obesity, insulin resistance, and cardiovascular disease. This review summarizes our current understanding of the sources and metabolism of LPA with focus on the influence of diet on circulating LPA. Furthermore, we explore how the ATX-LPA pathway impacts obesity and obesity-associated disorders, including impaired glucose homeostasis, insulin resistance, and cardiovascular disease.

    Physical Violence in Family Sub-Systems: Links to Peer Victimization and Long-Term Emotional and Behavioral Problems2018In: Journal of family Violence, ISSN 0885-7482, E-ISSN 1573-2851, p. 1-11Article in journal (Refereed)
    Abstract [en]

    Although childhood violence by any person is negative for children, little is known about whether violence by different family members is linked differently to problems in young adulthood, as family relationships might play different roles in children’s individual development. In this study, we examine parent and sibling violence and associations with emotional and behavioral problems, directly and indirectly via peer victimization. We used retrospective reports from 347 young adults (aged 20–24) who all reported childhood family physical violence, and we performed a path analysis using Mplus. The results showed that participants who had been victimized by a sibling only or by both a sibling and parent were more likely to report peer victim- ization than were participants who had been victimized by parents only. Peer victimization was, in turn, linked to more aggres- sion, criminality, and anxiety. Theoretical and clinical implications of these results are discussed.
