    Våld i nära relation: – Varför stannade hon kvar?2020Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Våld mot kvinnor är ett globalt samhällsproblem, där diskussionen om kvinnans roll i en våldsam relation kan leda till att skuldbelägga kvinnan för att hon stannar kvar, inte gör motstånd och inte håller den våldsutövande partnern ansvarig för våldet.  Arbetets syfte är utifrån kvalitativ metod klargöra de faktorer som kan leda till att kvinnor stannar respektive lämnar sina våldsamma partners. Forskningen angående våld i nära relationer är väldokumenterat, med Lundgrens (2012) normaliseringsprocess och exitprocessen (Holmberg & Enander, 2004) i spetsen för de specifika teorierna. Allmän teori angående våld och aggression av Anderson och Bushman (2002) beskriver att mottagare av våld svarar med liknande beteenden, vilket de specifika teorierna inte framställer. Resultatet visar att upplevelserna från informanterna drar nästan raka paralleller med normaliseringsprocessen och exitprocessen med dåligt självförtroende, beroende av den våldsamma partnern samt tvivel och motstånd som huvudtema. Informanternas upplevelser finner lite stöd från allmän teori utifrån dem själva, men kan kopplas till hur de beskriver expartnernas motivationer och beteenden.

    Bomber och sprängningar, hur förändras vårt beteende av kriminalitet?2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I denna kandidatuppsats undersökte vi beteende och emotionsförändringar i samband med sprängdådet i Linköping den 7 juni 2019. Det är en kvantitativ studie där boende i Linköping deltog. Syftet med studien var att undersöka om avståndet mellan området där man bor och platsen för sprängningen har betydelse för graden av emotions och beteendeförändring efter händelsen. Ett förväntat resultat var att de som bor geografiskt nära sprängningen skulle få en högre grad av förändringar än boende längre bort och det visade sig stämma. Hypoteserna får stöd av resultatet som visar tydligt att efter sprängningen ökar benägenheten hos de som bor närmast (2 km från händelsen) att ta avstånd till okända människor. Människor i området närmast har svarat att de ändrat rörelsemönster i hur de tar sig fram och vistas i staden samt att de fått större känsloförändringar. De som bor närmast händelsen har fått störst beteendeförändringar totalt.

    “Doing things together”: Towards a health promoting approach to couples’ relationships and everyday life in dementia2020Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Background: Most people with dementia live in their own homes, often together with their partners, who become informal caregivers. Relationship quality and sense of couplehood can be threatened as a result of the transition from a mutually interdependent relationship to a caregiver-care-receiver relationship. This, in turn, may lead to many negative consequences for both partners. Support provided for couples is often divided into different types for the person with dementia and for the partner without dementia and lacks couple-based support that targets the relationship, resources and the couple’s everyday life together.

    Aim: The overall aim of this thesis is to explore couple-centred interventions in dementia and to develop and test a salutogenic, resource-oriented and couple-based intervention among couples in which one partner has dementia living at home.

    Methods and findings: This thesis comprises three parts: The first part Exploring involves two linked reviews, one narrative review (study I A) and one scoping review (study I B) that aim to identify and describe what previous couple-centred interventions comprised and why they were conducted. The results of the reviews revealed a knowledge gap in and a need for easily accessible support that targets couple relationships, resources and everyday life. The second part Developing (study II) refers to the development of an easily accessible resource-oriented couple-management intervention. The first step was to identify priority topics for such an intervention through a co-researcher process with couples living with dementia. This included a comprehensive literature review, interviews with couples in which one partner has dementia, and consultation meetings with expert groups of people with dementia and partners in both Sweden and the UK. The co-researcher process and the expert meetings informed four main themes with corresponding sub-themes that couples with dementia considered as important to their wellbeing in their everyday lives: (1) Home and Neighbourhood, (2) Meaningful Activities and Relationships, (3) Approach and Empowerment, and (4) Couplehood. The themes were further developed and integrated into the multimedia application DemPower, which was developed for the delivery of the intervention. The third part Testing and Evaluating describes a feasibility study (study III) in which the DemPower application was tested for feasibility and acceptability among couples in Sweden and the UK. The results of the feasibility study indicated that the DemPower intervention was feasible and acceptable among couples in which one partner has dementia living at home. The testing and evaluating part also comprise a qualitative study (study IV) that explores the experiences of engaging with DemPower together as a couple living with dementia in Sweden. The findings resulted in the three themes: (1) Growth of the relationship, (2) We are not alone, and (3) Positive approach, which the couples appreciated and associated with the resource-oriented and salutogenic approach of DemPower. The overall findings of the thesis are presented in a concluding synthesis at the end of the thesis. The concluding synthesis, focused on “Meaningfulness”, “Empowering health promotion”, “Normalization” and “Transitions and couplehood”, represents the core findings of this thesis.

    What this thesis adds: This thesis contributes to research, healthcare and the public by highlighting the need for a salutogenic approach toward couples living with dementia. The DemPower application, with its focus on couples’ relationships, resource-orientation and everyday life, has proven feasibility and acceptability and has meaningfully addressed a gap in the literature and in practice. As researchers, healthcare professionals and the public, we need to support couples where one partner has dementia to continue to live as normal life as possible. This can best be achieved by focusing on what couples can do, by inclusion and by valuing them as the experts within dementia research and of their life experiences.

    Abstract [en]

    Introduction Symptoms of dementia bring about challenges to couples relationships. Relationship-focused support has been highlighted to be of significant importance for sustained relationship quality and to reduce the negative impact of dementia on the dyadic relationship. This review aimed to explore the what and why of interventions aimed at couples where one partner has a diagnosis of dementia and in which the couple jointly participate. Method Searches were performed in Academic Search Premier, CINAHL, PsycINFO, PubMed, Scopus and Web of Science from January 2000 to August 2017. Results Six studies were included. Objectives for the person with dementia was related to cognitive function and for the care partner the objectives were related to well-being. The majority of the outcomes were mirrored by the objectives and focused on cognitive function for people with dementia and depression and relationship quality for care partners. Our findings indicate that people with dementia should be included in the assessment of the relationship in order to gain an overall picture of relationship dynamics and to increase tailored support in couple-centred interventions. Conclusions The findings of this review indicate that joint interventions for people with dementia and care partners are lacking a genuine dyadic approach where both partners views of their relationship are valued. In order to identify targets for support and to use the appropriate outcome measures, the quality of the relationship should be recognised and taken into account. Moreover, there is a lack of a salutogenic approach in couple-centred interventions in which couples strengths and resources can be identified and supported.

    Abstract [en]

    The aim of this study is to identify relevant content for a self-management guide by using the outcomes of previous research in combination with knowledge and experiences from couples where one partner has a diagnosis of dementia. The study was carried out in three phases: (a) literature search of previous research related to well-being and couplehood in dementia; (b) interviews with couples with dementia based on the findings of the literature search; and (c) further authentication of the findings within expert groups of people with dementia and carers. For analysis of data, we used a hybrid approach of thematic analysis with combined deductive and inductive approaches. The findings of this study indicated that the four main themes Home and Neighborhood, Meaningful Activities and Relationships, Approach and Empowerment, and Couplehood with related subthemes could be appropriate targets for a self-management guide for couples where one partner has a diagnosis of dementia.

    Narratives of Norrköping2019Report (Other academic)
    Abstract [en]

    Narratives of Norrköping, the 3rd edition of the REMS publication, aims to be exactly as the title suggests: a collection of narratives from a spectrum of different people residing in our city of Norrköping.

    As with previous editions, this magazine has been created by 1st year students of the Ethnic and Migration Studies Master’s programme of Linköping University. An eclectic mix of people in their own right, the authors of the following texts have a hugely diverse and rich background of different cultures and narratives. They came together here in Norrköping to learn more about the ever more important field of migration and ethnicity.

    An interdisciplinary and transformative course like Ethnic and Migration Studies constantly shifts the world view of the students studying it. From the way we look at political systems, to how minorities and refugees are treated; analysing infinitely different aspects of society can only lead us to change how we associate with the city around us. Norrköping is the city that now the majority of us call home, and it was a pleasure to come together to look outwards into the community to create this work.

    The large variety of different authors brought together can be seen in the writing and design styles, which are individual to the authors. Both a mix of academic and journalistic styles, we hope that the reader can appreciate the personal touch of each of the pieces.

    Authors aside, we would also like to give special thanks to the support and teachings of the staff of REMESO, and we must be particularly grateful to the fellow local residents who have been interviewed and have been willing to tell their story to a group of over enthusiastic students. Without them, there would be no stories to tell, and equally no community around us.

    We hope that the following articles will provide some insight into the lives of more of the people around us, the city of Norrköping itself, and more of a taste of the forever enriching and changing culture surrounding us.

    Special thanks to the following people who went above and beyond to give their time, also to those who preferred to stay anonymous:

    Verksamhetsberättelse Linköpings universitetsbibliotek (LiUB) 20192019Report (Other academic)
    Abstract [sv]

    2019 var året när biblioteket äntligen flyttade in i Studenthuset! Mycket planering gjordes under våren så att den faktiska flytten under sommaren gick mycket bra. Många medarbetare kom tillbaka från sina ledigheter till en helt ny arbetsplats. Relativt till projektets storlek och komplexitet har uppstarten i Studenthuset gått mycket bra. Självklart har det funnits detaljer att rätta till eller reda ut. Exempelvis har det varit nödvändigt för avdelningarna Campus Valla och Mediaförsörjning att utveckla helt nya arbetsrutiner, vilka nu har börjat landa.

    2019 har också varit ett intressant år ur avtalsperspektiv. Biblioteket har varit utan avtal med Elsevier under ett helt år. Det har inneburit att tjänsterna Fjärrlån och Get-it-Now har haft mycket högre användning än vanligt. Bibliotekets fjärrlånegrupp har dock klarat av det ökade trycket och levererat bra i alla fall! Vid årsskiftet 2019/2020 kommer ett nytt avtal att vara på plats. Under 2019 tecknade UB ett "transformativt" avtal, vilket också kan kallas "read and publish-avtal" (dvs ett avtal som ofta mot en extra betalning gör att LiU :s artiklar blir fritt tillgängliga till alla utan extra kostnad för författare). De pengar som inte behövdes till Elsevier-prenumerationen användes delvis för en OA-fond vilket innebar att UB betalade publiceringsavgifter för LiU:s artiklar i ren open access tidskrifter. Resultatet är att en betydande del av LiU:s publikationer har blivit fritt tillgängliga.

    Under året kan också noteras att bibliotekets undervisning har fortsatt sin förändringsresa; att DigiMaker har haft ett mycket aktivt program och expanderat till Campus Norrköpingsbiblioteket; att sessioner om Python, Excel och GitLab har varit fulltecknade; att ett projekt med biblioterapi har lanserats; att forskare har fått hjälp av sökstödsgruppen; att stöd till doktorander har börjat utökas, att serien med lunchföreläsningar "Dubbelkvart på biblioteket" startade osv. Med andra ord: Biblioteket står inte still!

    Simmulating pullout forces in particleboard2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Pull-out forces of screws and connectors in particleboard are particularly important when designing for strength and, or assembly in the furniture industry. The aim of this thesis was to develop a simulation model of particleboard that can predict pull-out forces of screws better than the currently used simulation model at IKEA of Sweden. The developed model was validated against experimental results from pull-out tests carried out by IKEA.

    Material properties for particleboard are determined from experiments previously carried out at IKEA test labs unless stated otherwise in the report. The authors did not carry out any tests. In order to simulate the pull-out forces of a screw, the finite element method was employed, simulation models from three different material models selected from the Finite Element Analysis (FEA) software LS-DYNA. The first material model considered Mat_143, a wood material model based on the Hashin failure criterion and used to develop simulation model 1. The second material considered, Mat_122 3D, based on Hill’s plasticity theory, was used with Mat_Add_Generalised_Damage to allow for incremental damage accumulation and failure. This was simulation model 2. The third one, Mat_221 which represents an orthotropic material with simplified damage, was used to develop simulation model 3.

    Experimental test results for tensile test, bending test, shear test and, finally, the screw pull-out test was used to validate the simulation models. Before the scale validation, a single hexahedral element was simulated to evaluate the accuracy of the simulation models and to get a better understanding of the limitations of the material models. A mesh type and convergence study was carried out where it was concluded that the first- and second-order hexahedral and tetrahedral elements could be employed for the full model simulations, giving a sufficiently accurate result, i.e. matching the experimental results by at least 86%. An element size range of 1-3 mm was enough for quasi-static load cases and while an element size range 0.15-3 mm was relevant for dynamic load cases. Model 1 was abandoned when it was discovered the material model was not suitable for predicting material behaviour other than that of wood for a large mesh.

    The remaining two simulation models were evaluated for tensile, shear and bending load cases. Simulation model 2 predicted both tensile and bending forces with an accuracy of 99% or higher, and predicted shear forces with an accuracy of 86%. Simulation model 3 predicts both tensile and shear forces with an accuracy of 98% or higher and predicted bending forces with an accuracy of 86%.

    For the screw pull-out test, simulation models 2 and 3 under-predicted the pull-out forces significantly due to premature shear failure.iiiThe currently used particleboard simulation model is referred to as simulation model 4 throughout the report. Simulation model 4 was the most accurate simulation model for predicting pull-out forces in particleboard.

    Tuning the stress in TiN films by regulating the doubly charged ion fraction in a reactive HiPIMS discharge2020In: Journal of Applied Physics, ISSN 0021-8979, E-ISSN 1089-7550, Vol. 127, no 10, article id 103302Article in journal (Refereed)
    Abstract [en]

    In the present study, we investigate the impact of pulse power (Ppulse) on the ion flux and the properties of TiN films using reactive high-power impulse magnetron sputtering. Ppulse was adjusted in the range of 5–25 kW, while keeping the total average power constant through regulating the pulsing frequency. It is found that the required N2 flow, to produce stoichiometric TiN, decreases as Ppulse is increased, which is due to a decrease in the deposition rate. The plasma conditions when stoichiometric TiN is formed were investigated in detail. In situ ion mass spectrometry measurements of the ion energy distribution functions reveal two distinct ion populations, ions originating from sputtered atoms (Ti+, Ti2+, and N+) and ions originating from the working gas (Ar+, Ar2+, and N2+). The average ion energies (Eave) of the sputtered ions show an increase with increasing Ppulse, while Eave for the gas ions remains almost unaffected. The relative flux intensity Ti2+/Ti+ showed an increasing trend, from 0.28 to 0.47, as Ppulse was increased from 5 to 25 kW. The ion flux changes affect the growth of the TiN film such that 111-textured films are grown for low Ppulse while higher Ppulse results in mixed orientations. In addition, the hardness of the deposited film increases with increasing Ppulse, while the compressive film stress increases significantly at a higher Ppulse. In this way, optimum deposition conditions were identified at Ppulse = 8.3 kW, where a relatively low compressive stress of 0.89 GPa and high hardness of 22.67 GPa were measured.

    Managing Quality in Cross-cultural Settings2020Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    As companies become multinational with subsidiaries in different countries and global customers, they face challenges in managing quality related to cultural diversity. During the past decades, cross-cultural quality management research has emerged, aiming to understand the link between culture and quality management, and to provide support for quality management in different cultural contexts. This research field becomes increasingly important considering global industries of today. Nevertheless, the first standpoint in identifying challenges in cross-cultural quality management in multinational companies remains to be an open question. This also leads to the need for developing an instrument to understand cultural diversity in quality management, from both an internal perspective related to employees and an external perspective related to customers.

    This thesis aims to provide an insight into managing quality in cross-cultural settings, focusing on both multinational companies and companies having global customers. Three studies have been conducted combining qualitative and quantitative research methods. First, case studies were employed to explore the research field and identify challenges in managing quality related to national cultural diversity in multinational companies. The second study developed an instrument based on anchoring vignettes survey to understand cultural diversity in quality management and applied it in two settings. The third study combined an interview-based study with a case study using mixed methods to further investigate and consolidate the results gained from the first two studies, leading to the suggestion of possible strategies to manage quality in multinational companies.

    The thesis findings identify three challenges in managing quality in multinational companies: 1) to translate and implement quality management approaches; 2) to motivate and engage employees in quality work; and 3) to establish shared perceptions of quality management values among employees. Further, an instrument based on anchoring vignettes is suggested to study quality management performance across subsidiaries and to measure customer satisfaction across borders. This instrument contributes to better understanding of cultural diversity and improves the comparability of survey results in quality management measurements. Regarding possible strategies, global integration is needed when a quality culture is weak. In the long-term, companies should promote technical aspects of quality management to form a ‘backbone’ of the quality management system and to set a basis for shared perceptions of quality management values and goals. Consequently, a strong quality culture can be established and companies can benefit from local adaptation of practices.

    Abstract [en]

    Lean principles and methods, originating in a Japanese cultural context, have spread to a large number of companies throughout the world. The aim of this case study research is to identify and compare national cultural aspects that influence Lean Production and Lean Product Development implementation in Swedish companies. Data were collected through questionnaires, interviews and an industrial workshop with Swedish Lean practitioners. The study shows that some sub-areas in Lean, such as value definition, control systems, leadership, team development, knowledge management, and strategies, are highly dependent on contextual factors related to human, cultural and organizational aspects. These are related to the national culture and should be considered to a higher extent for successful sustainable implementation of Lean in different cultural contexts. As for implementing Lean in Sweden, national cultural characteristics, such as individualism, autonomy and supportive management style fit well with Lean thinking.

It has been proposed that quantum coherence plays a role in the formation of charge carriers in organic photovoltaics, but experimental proofs have been lacking. Here we report experimental evidence of coherence in the charge separation process in organic donor/acceptor heterojunctions, in the form of low frequency oscillatory signature in the kinetics of the transient absorption and nonlinear two-dimensional photocurrent spectroscopy. The coherence plays a decisive role in the initial ~200 femtoseconds as we observe distinct experimental signatures of coherent photocurrent generation. This coherent process breaks the energy barrier limitation for charge formation, thus competing with excitation energy transfer. The physics may inspire the design of new photovoltaic materials with high device performance, which explore the quantum effects in the next-generation optoelectronic applications.

    "Det här är lätt, jag är bara inte så snabb": En studie av två interventionsprogram för att öka elevers i årskus 7 beräkningsflyt vid huvudräkning av grundläggande additioner och subtraktioner inom talområdet 0 - 202020Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    För att elever i matematiksvårigheter ska utvecklas i sin matematik behöver i de flesta fall den grundläggande taluppfattningen utvecklas. En viktig del i grundläggande taluppfattning är att ha flyt i beräkningar av de grundläggande additions-och subtraktionskombinationerna. För att uppnå detta kunnande beskrivs i litteraturen att kunskaperna behöver automatiseras, överinläras eller komprimeras. Elever som inte lär sig effektiva strategier för beräkning byggda på förståelse av de ingående begreppen och utvecklar beräkningsflyt tenderar att fortsätta använda ineffektiva beräkningsstrategier genom hela sin skolgång. Beräkningsflyt möjliggör lärande av mer komplex matematik och lösande av matematiska uppgifter på en högre nivå då arbetsminnet avlastas dessa beräkningar.

    I föreliggande studie undersöktes två tier 2-interventioners effekt på elevers flyt vid beräkning av grundläggande additioner och subtraktioner inom talområdet 0–20 samt på elevernas attityder till matematik. En intervention var digitaliserad där elever övade inom sin ordinarie undervisningsgrupp via en pedagogisk websida och den andra interventionen var lärarledd medexplicit undervisning av beräkningsstrategier och träning med 1-minute-timings i liten grupp. I studien ingick19 elever i årskurs 7. Syftet var att undersöka om det fanns någon skillnad i effekt mellan interventionerna på elevernas beräkningsflyt och attityder.

    Resultaten visar att båda interventionerna hade positiv effekt på elevernas flyt vid beräkningar av grundläggande additioner och subtraktioner. Förbättringen av elevernas beräkningstempo är större i den lärarledda interventionen än i den digitaliserade interventionen. Den statistiska analysen visade på en signifikant interaktionseffekt av tid och interventionsgrupp.

    Resultaten pekar på att interventioner för att öka beräkningsflyt bör vara lärarledda och innehålla explicit undervisning av beräkningsstrategier, samt 1-minute-timings, för att ha störst effekt. Interventionerna ledde inte till någon attitydförändring hos eleverna.

    Ledarskap för hälsa och välbefinnande: Kunskapssammanställning 2020:62020Report (Refereed)
    Abstract [sv]

    I denna rapport presenteras en kunskapssammanställning som inriktats mot forskning som undersöker ledarskapets betydelse för medarbetares hälsa och välbefinnande. Kunskapssammanställningen har genomförts inom ramen för ett regeringsuppdrag till Myndigheten för arbetsmiljökunskap med syfte att sammanställa kunskap om faktorer som skapar friska och välmående arbetsplatser (dnr A2018/01349/ ARM). Syftet med studien är att sammanställa forskningsbaserad kunskap om vilka ledarskapsbeteenden som kan bidra till hälsa på arbetsplatsen. Detta syfte har brutits ned i tre frågeställningar: Vilka teoretiska utgångspunkter gällande ledarskap och/eller chefskap finns i empiriska artiklar om ledarskap som främjar hälsa och välbefinnande? Hur har detta ledarskap studerats från ett metodologiskt perspektiv och i vilka kontexter har det studerats? Vilka direkta och indirekta ledarskapsbeteenden som främjar hälsa kan identifieras i tidigare forskning?

    Det systematiska arbetet med kunskapssammanställningen har följt den så kallade Mynakmodellen. Inledningsvis tydliggjordes översiktens innehåll, fokus och avgränsningar på basis av studiens syfte och frågeställningar. Därefter formulerades kriterier för vilka studier som skulle inkluderas respektive exkluderas i sökning och granskning. Inklusionskriterierna var att studierna skulle ha fokus på arbetslivs och arbetsplatskontexter, skulle vara utförda i en nordisk kontext, skulle undersöka ledarskap i termer av stilar, beteenden, roller och liknande begrepp eller synonymer samt att studierna skulle fokusera på relationen mellan ledarskap och anställdas hälsa och välbefinnande på arbetsplatsen. Ytterligare avgränsningar som fastställdes var att studierna skulle vara vetenskapliga artiklar i internationella (akademiska) tidskrifter med granskningsförfarande (eng. peer-reviewed), att de skulle vara publicerade mellan 2009 och 2019 samt att de skulle vara skrivna på engelska och innehålla empiriskt material. Exklusionskriterierna bestod av att inte ta med studier som a) enbart fokuserade på andra kontexter än arbetslivet, till exempel skola och utbildning (till exempel studier av relationer mellan lärare och elever), b) enbart var genomförda i en utomnordisk kontext, c) enbart fokuserade på indirekt ledarskap, d) enbart fokuserade på destruktivt ledarskap, e) enbart fokuserade på ohälsa. Vidare bestämdes att studier skulle exkluderas om de f) inte byggde på empiriskt material (som till exempel litteraturöversikter, metaanalyser, konceptuella artiklar, eller motsvarande), g) var litteratur som inte publicerats i vetenskapliga, akademiska tidskrifter (som till exempel rapporter, böcker och bokkapitel), h) var skrivna på andra språk än engelska.

    Sökningarna har huvudsakligen genomförts i databasen Scopus. Databasen Web of Science användes som komplementdatabas. Scopus genererade 2463 träffar och Web of Science genererade 1499 träffar. Efter att dubbletter tagits bort kvarstod 2859 unika studier vilka därefter sållades utifrån titel och abstract. Totalt var det 491 studier som ansågs kräva fulltext för att avgöra om studien uppfyllde uppställda inklusionskriterier. Efter att fulltexterna hämtats in påbörjades relevansgranskningen utifrån studiens inklusionskriterier. 37 studier uppfyllde samtliga relevansbedömningspunkter. Dessa studier genomgick en kvalitetsbedömning utifrån vedertagna protokoll för kvantitativa och kvalitativa studier. Av totalt 31 kvalitetsgranskade kvantitativa studier bedömdes 28 studier ha hög eller medelhög kvalitet. Av total sex kvalitetsgranskade studier bedömdes fem kvalitetsgranskade kvalitativa studier ha hög eller medelhög kvalitet. Totalt har således 33 studier ingått i granskningen. De inkluderade kvantitativa studierna har analyserats utifrån det som kallas narrativ sammanställning och de kvalitativa studierna har analyserats utifrån en konventionell innehållsanalys.

    Sammanfattningsvis visar studierna som ingår i kunskapssammanställningen att ledarskap är relaterat till medarbetares hälsa och välbefinnande. Nästan alla kvantitativa studier visar att det finns ett samband mellan ledarskap och hälsorelaterade utfall om inga andra faktorer vägs in. Då det är många olika typer av utfall som används i studierna är det svårt att ge en tydlig och enhetlig bild, men framförallt har så kallat transformativt ledarskap och stödjande ledarskap samband till anställdas hälsa och välbefinnande, särskilt i relation till de arbetsrelaterade hälsoutfallen, som till exempel arbetstillfredsställelse och arbetsengagemang. I de kvalitativa studierna betonas framförallt ett relationsorienterat och demokratiskt ledarskap, vilket kännetecknas av en ledare som motiverar och inspirerar sina medarbetare, är tillgänglig och lyssnar på sina medarbetare och som samtidigt har förtroende för sina medarbetares förmågor och ger dem ansvar, utrymme och medbestämmande. Vad de kvalitativa studierna pekar på som viktiga beteenden är också till stora delar aspekter som återfinns i ledarskapsteorierna och de skalor om ledarskap som används på området. Dessa båda metoder ger alltså tillsammans en klarare bild över vilka slags ledarskapsbeteenden som främjar hälsa.

    Studierna framhåller också indirekt ledarskap som något som påverkar medarbetarnas hälsa och välbefinnande. Sammantaget pekar studierna ut flera olika slags faktorer som ledarskapet verkar genom. En faktor handlar om själva uppgifterna och förutsättningarna som ges för att utföra dessa. En annan faktor handlar om det sociala klimatet och miljön på arbetsplatsen eller i organisationen. En tredje faktor handlar om individen och dennes inställning till arbetet och den fjärde faktorn handlar om hälsofrämjande aktiviteter och insatser. Här är det svårt att säga att någon särskild ledarstil i relation till något särskilt hälsoutfall skulle vara ”bättre” eller ”sämre”. Transformativt ledarskap är det ledarskap som undersökts mest och är också det ledarskap som flest studier finner verkar genom andra faktorer i arbetsmiljön.

    Utifrån arbetet med sammanställningen har ett antal kunskapsluckor identifierats. Fältet domineras av kvantitativa studier som utgår från abstrakta ledarskapsteorier utvecklade i en nordamerikansk kontext. Dessa studier konstaterar förekomster av samband mellan ledarskap och hälsa, men de säger lite om hur ledarskapet utförs i praktiken, på vilket sätt ledarskapet påverkar hälsan och hur de förutsättningar som råder i den nordiska arbetsmarknadsregimen påverkar ledarskapets utövande. Vidare saknas kunskap om den organisatoriska kontextens betydelse för ledarskapet och vilka roller som medarbetarna själva spelar när ledarskapet utövas. Sammantaget finns det behov av teoretiskt och metodologiskt mångsidiga, longitudinella studier som jämför olika kontexter och som samlar data om hur ledarskapet utförs, till exempel genom observationer. Utifrån kunskapssammanställningen presenteras också några allmänna råd för den som arbetar med att främja medarbetares hälsa och välbefinnande i organisationer. Här poängteras att ledarskapet är ett situationsberoende fenomen och att det inte går att hitta ett ledarskap som fungerar överallt. Detta innebär att de ledarbeteenden som i forskning identifierats som främjande av hälsa och välbefinnande, som till exempel att vara tillgänglig, visionär, inspirerande och inkluderande, kan ses som goda källor till inspiration, men att de behöver anpassas till de förutsättningar som råder i den specifika kontexten. Förutom ledarens beteenden i relationen till medarbetarna visar forskningen också att ett indirekt ledarskap är betydelsefullt för att till exempel bygga en kultur och miljö som främjar hälsa.

    Hantering av akutflöden: Faktorer att ta hänsyn till vid organisering kring akuta patientflöden2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The Swedish health care sector is facing the challenge of an aging population and a growing need for medical care. Parallel to this, the development of new treatments makes it possible to treat more illnesses. The demand on medical services to care for and treat more patients will thus increase. Many reports indicate that the Swedish healthcare system, compared to other countries, has a low productivity. Slow patient flow through hospitals have been identified as one factor. Slow patient flow also prolongs waiting times and prevents patients from receiving care in time. A state investigation of the problems in the Swedish health care system, conducted by Stiernstedt (2016), emphasizes that improved patient flow through the hospital must be given priority. Olsson (2014) also stresses the need for a systemic view from those involved in the flow, to avoid sub-optimization. Stiernstedt (2016) continues and stresses that both the strategic and operational management of flows, should be identified and developed, as well as the interaction between them. Skaraborg Hospital Skövde (SSS) is a Swedish, medium-sized, hospital that has identified problems with its own acute patient flow and wants to improve their pertained management. In this study, a qualitative description and analysis of how the SSS manages its emergency flow, was conducted. Focus was mainly on examining acute flow related practices and identify limiting or problematic factors regarding these practices. The study is a continuation of the hospital's own mapping of acute flows. Based on the organization's worked out description of acute flow and associated processes, key personnel’s perception of problematic factors was captured. Interviews were conducted with representatives from different organizational levels of the hospital. Data, collected from the interviews, have been analyzed on the basis of, primarily healthcare related, theories of flows and theories of cooperation between professionals and different organizational levels in a hospital. Based on the analysis, several recommendations were given to the hospital regarding flow management. Given the particular circumstances found in a medical context, along with ever-increasing production requirements, the management of patients in an acute flow of is a research area that needs to be further elucidated. The theoretical groundwork of this study can be a basis for further deepening and understanding of management regarding acute patient flows.

    ‘Looping effects’ related to young people’s mental health: How young people transform the meaning of psychiatric concepts2020In: Global Studies of Childhood, ISSN 2043-6106, E-ISSN 2043-6106, Vol. 10, no 1, p. 26-38Article in journal (Refereed)
    Abstract [en]

    Over the past decades, reports from official authorities and the media have suggested that there is a ‘crisis’ in young people’s mental health. However, there is considerable uncertainty regarding how to interpret the data referred to in these alarming reports. The present article draws on ‘the minority voices’ of young people and theories developed by Ian Hacking to undertake a critical analysis of the conceptualisation of young people’s mental health. According to Hacking, systems of classifications formulate general truths about people and frame the suffering of individuals in specific ways. Classification changes people. However, young people are social actors who interact with classifications of their mental health and by doing so they could cause classifications to be redrawn. Hacking refers to these feedback effects as ‘looping effects’. Based on 51 interviews with 15-year-olds, this article explores how young people interact with psychiatric labels associated with their wellbeing such as anxiety and depression. We demonstrate how the participants gave new meaning to these psychiatric labels, devalued and gave nuance to them, and by doing so transformed them into cultural categories rather than diagnostic categories. We discuss the potential looping effects related to young people’s mental health and how the present findings can inform policy practice.

    Doctoral education in the entrepreneurial university: enhanced employability?2020Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This dissertation explores the issue of employability of doctorate holders through the theoretical lens of the model of the entrepreneurial university. It starts from the observation that there is a bottleneck in the academic labour market in many countries, making it increasingly difficult for recent doctoral graduates to engage in an academic career. Traditionally, doctoral education was designed for a career in academia; but the employment situations of doctorate holders call for more relevance of doctoral education and doctoral-level skills on the non-academic labour market. The main argument of this dissertation is that the openness and the interactions of the entrepreneurial university with its environment, in particular its region, makes it a relevant model to enhance the employability of doctorate holders outside academia. The thesis is based on five publications written either solely by the author or in collaboration with other scholars, mostly case studies compiling both qualitative and quantitative data and approaches.

    Three main findings can be highlighted from the research: (i) the entrepreneurial university increases its socioeconomic impact by building an alignment with regional stakeholders over the years and thanks to key individuals, by retaining human and social capital within itself and by broadening the scope of its activities and stakeholders; (ii) doctorate holders’ employability is key in the entrepreneurial university’s regional socioeconomic impact, as they are increasingly employed outside academia but are likely to experience job mismatches in this situation, mainly related to education and skills; (iii) regional stakeholders can take different types of initiatives to enhance the employability of doctorate holders, and increase the entrepreneurial university’s socioeconomic impact: more specifically, doctorate holders and non-academic employers can get to know each other better; intermediaries such as Science Parks can support them through the creation of meeting places.

    The dissertation contributes to the literature on the entrepreneurial university by focusing on the population of doctoral students and doctorate holders, at the crossroads of its three missions (education, research and ‘third mission’). It also suggests the following main recommendations: to universities, beyond adapting the content of doctoral education to the needs of non-academic employers, put emphasis on marketing it to them, so that they understand what it is worth; to doctorate holders, expand their knowledge of career possibilities, and behave entrepreneurially by initiating activities to complement what could be missing in their education; to non-academic employers, collaborate with universities and communicate their needs to them to influence the design of curricula.

    Abstract [en]

    Many studies have shown that they have ceased to be mere facilitators of physical spaces to become important providers of services and resources to their tenants. Universities situated in or next to them play a key role in getting engaged in the development and the attraction of talent to Science Parks, to their tenant firms as well as to the region. Considering that skilled professionals are one of the resources that companies seek the most, Science Parks have dedicated numerous activities and means to become even more attractive to talented individuals, who can especially be found in entrepreneurial universities. In this study, we review the literature regarding the interactions existing between Science Parks or their tenants and their local universities. Talent attraction and entrepreneurship issues are addressed as the building blocks of these interactions. We strive to identify types of interactions that could differ in function of the maturity levels of the firms since their aims are not the same: at an early stage, firms tend to focus more on growth, whereas at a later stage, they tend to focus more on their development. We then point out policy implications, concerning both entrepreneurial or engaged universities and Science Parks.

    Abstract [en]

    Even though the doctoral degree was originally designed for an academic career, there is an increasingly important labour market for doctorate holders outside academia, mainly because of a shortage of job opportunities within it. Doctoral degrees are granted only by universities; thus, universities are the only suppliers of the doctoral workforce to the labour market. Understanding the needs of non-academic employers is thus crucial if universities are to adapt their doctoral education curriculum. Many studies have analyzed labour markets for doctorate holders at national and transnational scales, but few studies focus on the regional scale. The present study explores regional data for Catalonia in Spain on the employment situation of doctorate holders in order to define the characteristics of the regional, non-academic labour market for doctorate holders. Descriptive statistics suggest a high retention rate of doctorate holders within the region and a large part of doctorate holders (two-thirds) having a job that does not require a doctoral degree. This study highlights the existence of a skills mismatch that might be linked to the preference for a better paid or more stable job, or to the lack of development of skills that represent added value in the eyes of employers. These characteristics can be formulated as hypotheses to be tested in further qualitative or quantitative studies. They have several implications for universities, non-academic employers and regional policy-makers, such as the need to work on the valorization of the doctoral degree in the non-academic labour market.

    Abstract [en]

    Doctoral education was primarily designed to answer the human resources needs of academia. However, nowadays, increasing numbers of doctorate holders seek employment outside academia. Accordingly, doctoral education can be one of the means by which universities take part in the development of industry in their regions. This study explores whether and how doctoral-level skills are being adapted to the needs of local industrial employers in two different contexts. Two research and science parks situated next to research-intensive universities in Sweden and Spain were chosen as cases for an exploratory and comparative study. In these parks, local industrial employers conduct Ramp;D activities that make them potentially attractive destinations for doctoral graduates. Similarities in the cases were found regarding the process of adaptation of doctoral education at the adjacent universities to meet the industrial employers needs in the parks. Discrepancies are also highlighted regarding stages of development, institutional settings, geography and culture. Implications for several stakeholders are formulated to improve the process analysed in the study concerning better alignment of doctoral education with industrial employers need for generic skills.

    Digitalisering av lärares undervisning: Översikt och exempel från examensarbeten vid ämneslärarprogrammet i samhällskunskap2020Report (Other academic)
    Abstract [sv]

    Denna publikation är en del av rapportserien DINO – Digitalisering i nya offentligheter. Syftet med rapportserien är att publicera tidiga forskningsresultat som handlar om samhällets digitalisering i vid mening, och särskilt det som sker inom och i relation till offentliga verksamheter.

    Digitaliseringen av skolan handlar om ett offentligt sammanhang i allra högsta grad. Och bland lärarstudenterna som vi handleder på ämneslärarprogrammet i samhällsvetenskap har kraven på att arbeta med digitala verktyg och att ha digital kompetens fångat mångas intresse och uppmärksamhet. Vi vill därför ge en inblick i den kunskap som skapas kring temat i den här rapporten. Rapporten vänder sig till en intresserad allmänhet, men även forskare och universitetslärare som undervisar lärarstudenter, lärarstudenter som står i startgroparna för att skriva examensarbeten, samt aktiva lärare som vill få inblick i kollegors utmaningar och tillvägagångssätt när det gäller digitaliseringen och användningen av digitala verktyg i undervisningen.

    I rapporten vill vi dela med oss av relevanta sätt att studera och förstå hur lärare i grundskola och på gymnasiet kan undervisa med digitala verktyg, hur studenterna kan arbeta för att fånga detta, samt visa på resultat som framkommit ur examensarbetena.

    Optimal proportional representation2020Report (Other academic)
    Abstract [en]

    In a democratic proportional election system, it is vital that the mandates in the parliament are allocated as proportionally as possible to the number of votes the parties got in the election. We formulate an optimization model for allocation of seats in a parliament so as to minimize the disproportionality. By applying separable programming techniques, we obtain an easily solvable problem, and present a method for solving it optimally. The obtained solution is the feasible solution that has the minimal disproportionality (with the measure chosen), even in the presence of a parliament threshold, which is not always the case for the practical procedures used in many countries. We apply the approach to real life data from the last three elections in Sweden, and show that the result is better, i.e. more proportional, than what was obtained with the modified Sainte-Laguë method, which is presently used. A natural suggestion would be to use our method instead.

    We also consider the issue about constituencies, and suggest a procedure, based on the same kind of optimization problem, for allocating mandates in the constituencies, without changing the overall allocation with respect to parties. The numbers of mandates for the constituencies are based on the number of votes given, not on estimated numbers of inhabitants entitled to vote. This removes the need for compensatory mandates, and makes the question about sizes of the constituencies less important.

    Exploiting parallelization and synergy in derivative free optimization2020Report (Other academic)
    Abstract [en]

    Real life optimization often concerns difficult objective functions, in two aspects, namely that gradients are unavailable, and that evaluation of the objective function takes a long time. Such problems are often attacked with model building algorithms, where an approximation of the function is constructed and solved, in order to find a new promising point to evaluate. We study several ways of saving time by using parallel calculations in the context of model building algorithms, which is not trivial, since such algorithms are inherently sequential. We present a number of ideas that has been implemented and tested on a large number of known test functions, and a few new ones. The computational results reveal that some ideas are quite promising.

    Economic and Environmental Benefits of the ORC and the Willingness to Invest: A case study from a wastewater treatment plant and a small-scale combined heat and power plant2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In Sweden, as many other European countries, centralized large-scale electricity production has traditionally been used to meet the electricity and heat demand. During recent years however, small-scale producers have gained more ground and contributes more to the total electricity generation. Industrial systems such as sewage plants and small-scale district heating plants both have potential thermal power sources available and utilizing this to generate electricity could be an important contribution towards increasing the ratio and effectiveness of renewable energy sources and reduce the primary energy supply. The potential of the Organic Rankine Cycle has been acknowledged by many, with commercial development increasing exponentially during the recent decades. Unlike the traditional Rankine cycle which uses water as a working fluid, the ORC uses a refrigerant with a lower evaporation temperature, which makes it possible to produce electricity from heat of lower temperatures.

    This thesis has through reading literature and plant visits analyzed the effect of implementing an operation strategy at two different plants where ORCs has been installed. One wastewater treatment plant in Norrköping and one combined heat and power plant in Ronneby, Sweden. The operation strategy includes moving production of electricity to high demand hours as well as analyzing options for increasing the efficiency at the plants. In addition, this thesis also includes a questionnaire made in order to analyze what obstacles and motivations that affect the willingness to invest in ORC technology in Sweden.

    The result from this provides useful information for future work in order to see an increased establishment of the ORC on the Swedish market.The results show that by implementing an operation strategy at plant Norrköping the avoided electricity and heat cost from installing the ORC could be increased by 47% and the avoided emissions increased by 436%. For plant Ronneby the avoided electricity cost could be increased by 8% and the avoided emissions increased by 31%.

    The questionnaire shows that different plants have different prerequisites and viewpoints when it comes to investing in ORC technology. This can for example be differences in budget for investments, the workload of the employees or if there is available fuel to run the ORC. From this finding it becomes clear that if one wish to see an increase in ORC technology in today’s industry, it becomes vital to look at each individual plant and assess the situation from there. However, a trend shows that the reduced electricity cost and the reduction in global emissions are two strong motivations for heat plants and wastewater treatment plants to invest in ORC systems.

    Sounds on the margins of language at the heart of interaction2020In: Research on Language and Social Interaction, ISSN 0835-1813, E-ISSN 1532-7973, Vol. 53, no 1, p. 1-18Article in journal (Refereed)
    Abstract [en]

    What do people do with sniffs, lip-smacks, grunts, moans, sighs, whistles, and clicks, where these are not part of their language’s phonetic inventory? They use them, we shall show, as irreplaceable elements in performing all kinds of actions—from managing the structural flow of interaction to indexing states of mind and much more besides. In this introductory essay we outline the phonetic and embodied interactional underpinnings of language and argue that greater attention should be paid to its nonlexical elements. Data are in English and Estonian.

    Blind Channel Equalization for Shortwave Digital Radio Communications2020Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In this thesis the concept of Blind Channel Equalization has been examined and algorithms suitable to blindly equalize the channel are presented and evaluated on simulated data. The concept of blind equalization is to equalize a communica- tions channel without relying on a training sequence or pilot tone, which may be either unknown to the receiver or not exist at all. In total, seven blind equaliza- tion algorithms have been implemented, these are the: lms-cma (Constant Modu- lus Algorithm), rls-cma, mma (Multi Modulus Algorithm), rca (Reduced Constel- lation Algorithm), cna-6 (Constant Norm Algorithm), lms-dfe (Decision Feedback Equalization) and rls-dfe. The equalizers are designed as adaptive fir-filters that are recursively updated by either an lms- or rls-algorithm, according to a cost function specified by the chosen algorithm with the aim to appoximate the inverse h−1 of the communications channel h. Thanks to the recursive update the algorithms can easily be implemented either in offline or online systems.

    The results show that the rls-algorithms offer shorter convergence times and over all better performance than its lms counterparts. If the signal constellation is known by the receiver in advance the rls-dfe offers the best channel tracking ability, resulting in the lowest symbol error rate.The rls-cma offers the roughly the same mseR -performance (mean square error from the equalizer output to the closest radius of the constellation points) but it lacks the ability to handle the doppler shift as well as the rls-dfe does. The results also show that the mma, cna-6 and rca-algorithms do not offer any better performance than the more commonly used and studied lms-cma algorithm.

    When the receiver incorrectly assumes the signal constellation, it can identify the correct constellation. Test results show that the rls-cma is especially good at amplitde recovery, while the rls-dfe is suitable to recover the phase of the signal. Lastly the rca is useful to recover psk-4 modulated signals as its cost function match the psk-4 constellation.

    ASSESSING THE ECONOMIC POTENTIAL OF LANDFILL MINING: REVIEW AND RECOMMENDATIONS2019In: DETRITUS, ISSN 2611-4127, Vol. 8, p. 125-140Article, review/survey (Refereed)
    Abstract [en]

    As landfill mining (LFM) gains public attention, systematic assessment of its economic potential is deemed necessary. The aim of this review is to critically analyze the usefulness and validity of previous economic assessments of LFM. Following the life cycle costing (LCC) framework, (i) the employed methods based on goal and scope, technical parameters and data inventory, and modelling choices were contrasted with respect to (ii) the synthesized main findings based on net profitability and economic performance drivers. Results showed that the selected studies (n=15) are mostly case study-specific and concluded that LFM has a weak economic potential, hinting at the importance of favorable market and regulation settings. However, several method issues are apparent as costs and revenues are accounted at different levels of aggregation, scope and scale-from process to sub-process level, from private to societal economics, and from laboratory to pilot-scale, respectively. Moreover, despite the inherent large uncertainties, more than half of the studies did not perform any uncertainty or sensitivity analyses posing validity issues. Consequently, this also limits the usefulness of results as individual case studies and as a collective, towards a generic understanding of LFM economics. Irrespective of case study-specific or generic aims, this review recommends that future assessments should be learning-oriented. That is, uncovering granular information about what builds up the net profitability of LFM, to be able to systematically determine promising paths for the development of cost-efficient projects.

    DEVELOPING STAKEHOLDER ARCHETYPES FOR ENHANCED LANDFILL MINING2019In: DETRITUS, ISSN 2611-4127, Vol. 8, p. 109-124Article in journal (Refereed)
    Abstract [en]

    Understanding the perspectives of different stakeholders on emerging technological concepts is an important step towards their implementation. Enhanced Landfill Mining (ELFM) is one of these emerging concepts. It aims at valorizing past waste streams to higher added values in a sustainable manner. Yet, assessment of ELFM mainly focusses on environmental and private economic issues, and societal impacts are rarely analyzed. This study uses semi-structured interviews to build understanding for different ELFM practitioners and researchers and develops five stakeholder archetypes for ELFM implementation: the Engaged Citizen, the Entrepreneur, the Technology Enthusiast, the Visionary and the Skeptic. The archetypes outline major differences in approaching ELFM implementation. The stakeholder perceptions are put into context with existing literature, and implications for ELFM implementation and future research are discussed. Results show that differences in regulatory changes and technology choices are affected by different stakeholder perspectives and more research is needed to balance inner- and inter-dimensional conflicts of ELFMs sustainability. The developed archetypes can especially be helpful when evaluating social impacts, whose perception often depends on opinion and is difficult to quantify.

    INTEGRATION OF RESOURCE RECOVERY INTO CURRENT WASTE MANAGEMENT THROUGH (ENHANCED) LANDFILL MINING2019In: DETRITUS, ISSN 2611-4127, Vol. 8, p. 141-156Article in journal (Refereed)
    Abstract [en]

    Europe has somewhere between 150,000 and 500,000 landfill sites, with an estimated 90% of them being "non-sanitary" landfills, predating the EU Landfill Directive of 1999/31/EC. These older landfills tend to be filled with municipal solid waste and often lack any environmental protection technology. " Doing nothing", state-of-theart aftercare or remediating them depends largely on technical, societal and economic conditions which vary between countries. Beside " doing nothing and landfill aftercare, there are different scenarios in landfill mining, from re-landfilling the waste into "sanitary landfills" to seizing the opportunity for a combined resource-recovery and remediation strategy. This review article addresses present and future issues and potential opportunities for landfill mining as an embedded strategy in current waste management systems through a multi-disciplinary approach. In particular, three general landfill mining strategies are addressed with varying extents of resource recovery. These are discussed in relation to the main targets of landfill mining: (i) reduction of the landfill volume (technical), (ii) reduction of risks and impacts (environmental) and (iii) increase in resource recovery and overall profitability (economic). Geophysical methods could be used to determine the characteristics of the landfilled waste and subsurface structures without the need of an invasive exploration, which could greatly reduce exploration costs and time, as well as be useful to develop a procedure to either discard or select the most appropriate sites for (E)LFM. Material and energy recovery from land-filled waste can be achieved through mechanical processing coupled with thermochemical valorization technologies and residues upcycling techniques. Gasification could enable the upcycling of residues after thermal treatment into a new range of eco-friendly construction materials based on inorganic polymers and glass-ceramics. The multi-criteria assessment is directly influenced by waste- and technology related factors, which together with site-specific conditions, market and regulatory aspects, influence the environmental, economic and societal impacts of (E)LFM projects.

    Improving the Health of Individuals With Cerebral Palsy: Protocol for the Multidisciplinary Research Program MOVING ON WITH CP2019In: JMIR Research Protocols, ISSN 1929-0748, E-ISSN 1929-0748, Vol. 8, no 10, article id e13883Article in journal (Refereed)
    Abstract [en]

    Background: Cerebral palsy (CP) is one of the most common early onset disabilities globally. The causative brain damage in CP is nonprogressive, yet secondary conditions develop and worsen over time. Individuals with CP in Sweden and most of the Nordic countries are systematically followed in the national registry and follow-up program entitled the Cerebral Palsy Follow-Up Program (CPUP). CPUP has improved certain aspects of health care for individuals with CP and strengthened collaboration among professionals. However, there are still issues to resolve regarding health care for this specific population.

    Objective: The overall objectives of the research program MOVING ON WITH CP are to (1) improve the health care processes and delivery models; (2) develop, implement, and evaluate real-life solutions for Swedish health care provision; and (3) evaluate existing health care and social insurance benefit programs and processes in the context of CP.

    Methods: MOVING ON WITH CP comprises 9 projects within 3 themes. Evaluation of Existing Health Care (Theme A) consists of registry studies where data from CPUP will be merged with national official health databases, complemented by survey and interview data. In Equality in Health Care and Social Insurance (Theme B), mixed methods studies and registry studies will be complemented with focus group interviews to inform the development of new processes to apply for benefits. In New Solutions and Processes in Health Care Provision (Theme C), an eHealth (electronic health) procedure will be developed and tested to facilitate access to specialized health care, and equipment that improves the assessment of movement activity in individuals with CP will be developed.

    Results: The individual projects are currently being planned and will begin shortly. Feedback from users has been integrated. Ethics board approvals have been obtained.

    Conclusions: In this 6-year multidisciplinary program, professionals from the fields of medicine, social sciences, health sciences, and engineering, in collaboration with individuals with CP and their families, will evaluate existing health care, create conditions for a more equal health care, and develop new technologies to improve the health care management of people with CP.

    It Is So Swedish That You Have to Work2019In: NORA: Nordic Journal of Feminist and Gender Research, ISSN 0803-8740, E-ISSN 1502-394X, Vol. 27, no 2, p. 80-95Article in journal (Refereed)
    Abstract [en]

    Notions of gender equality are strongly linked to the Swedish self-image. This article explores returning Swedish migrant womens negotiations of heterosexual gender equality ideals based on their experiences of being housewives to middle- and upper-class men with work contracts abroad. From fieldwork conducted within two networks for returning Swedes, the article provides an analysis of the ways in which the women talk about work, gender equality, and domestic workers.The analysis of the womens accounts of gender relations shows that different ways of doing femininity are central in their narratives. By using the concepts emphasized femininity and gender-equal femininity the article highlights the different forms of femininity that can be traced in the womens narratives. Drawing from the empirical examples, it is shown that the women are troubled by Swedish gender equality ideals and express a feeling of not fitting in after returning to Sweden. I suggest that the womens articulations of not fitting in to (imagined) gender-equal Sweden tend to downplay the fact that they still have advantages that assist with fitting in from social positions such as class, whiteness, and (hetero)sexuality: positions which may create space for negotiating social norms in Sweden.

    Carbon dioxide and methane emissions of Swedish low-order streams-a national estimate and lessons learnt from more than a decade of observations2018In: LIMNOLOGY AND OCEANOGRAPHY LETTERS, ISSN 2378-2242, Vol. 3, no 3, p. 156-167Article in journal (Refereed)
    Abstract [en]

    Low-order streams are suggested to dominate the atmospheric CO2 source of all inland waters. Yet, many large-scale stream estimates suffer from methods not designed for gas emission determination and rarely include other greenhouse gases such as CH4. Here, we present a compilation of directly measured CO2 and CH4 concentration data from Swedish low-order streams (> 1600 observations across > 500 streams) covering large climatological and land-use gradients. These data were combined with an empirically derived gas transfer model and the characteristics of a ca. 400,000 km stream network covering the entire country. The total stream CO2 and CH4 emission corresponded to 2.7 Tg C yr(-1) (95% confidence interval: 2.0-3.7) of which the CH4 accounted for 0.7% (0.02 Tg C yr(-1)). The study highlights the importance of low-order streams, as well as the critical need to better represent variability in emissions and stream areal extent to constrain future stream C emission estimates.

    Making HPV Vaccines Efficient: Cost-Effectiveness Analysis and the Economic Assemblage of Healthcare in Colombia2018In: Science & Technology Studies, E-ISSN 2243-4690, Vol. 31, no 2Article in journal (Refereed)
    Abstract [en]

    Cost-effectiveness analysis is a strategy of calculation whose main objective is to compare for making decisions about the best, the most efficient solution (costs vs benefits) to a particular problem. Cost-effectiveness analysis not only provides a framework to compare healthcare interventions which in practice seem incommensurable; it also performs a set of assumptions regarding the nature of healthcare and individuals behaviour. This article analyses the role of cost-effectiveness analysis as a device to produce value in the introduction of human papillomavirus vaccines to Colombia. In different institutional pathways and decision-making scenarios cost-effectiveness has been the key issue that justified the inclusions and exclusions that such technology entails. Cost-effectiveness justified the definition of girls as the population target and the exclusion of boys from the risks and benefits of this technology. Cost-effectiveness analysis has been a key instrument in the sexualising and desexualising of cervical cancer and human papillomavirus vaccines through the rationalisation of economic benefits.

    Electrode Surface Composition of Dual-Intercalation, All-Graphite Batteries2017In: C-JOURNAL OF CARBON RESEARCH, ISSN 2311-5629, Vol. 3, no 1, article id 3010005Article in journal (Refereed)
    Abstract [en]

    Dual-intercalation batteries implement graphite electrodes as both cathodes and anodes and offer high specific energy, inexpensive and environmentally sustainable materials, and high operating voltages. Our research investigated the influence of surface composition on capacities and cycling efficiencies of chemically functionalized all-graphite battery electrodes. We subjected core-shell spherical particles and synthetic graphite flakes to high-temperature air oxidation, and hydrogenation to introduce, respectively, -OH, and -H surface functional groups. We identified noticeable influences of electrode surface chemistry on first-cycle efficiencies and charge storage densities of anion and cation intercalation into graphite electrodes. We matched oxidized cathodes and hydrogenated anodes in dual-ion batteries and improved their overall performance. Our approach provides novel fundamental insight into the anion intercalation process and suggests inexpensive and environmentally sustainable methods to improve performance of these grid-scale energy storage systems.

    Operator Training Simulator for an Industrial Bioethanol Plant2016In: Processes, ISSN 2227-9717, Vol. 4, no 4, article id 34Article in journal (Refereed)
    Abstract [en]

    Operator training simulators (OTS) are software tools for training process operators in large-scale industrial applications. Here, we describe the development, implementation and training of an OTS for a large-scale industrial plant for bioethanol production. The design of the OTS is based on conceptual analysis (previously reported by us in this journal) of various configuration alternatives and training procedures at the plant. In this article, we report on how the conceptual design is used in simulation models and graphical user interfaces and how the design is applied for training of operators in the real plant environment. The results imply that OTS would be time-and cost-efficient tools for application in the biotechnological industry.

    Building bridges to operationalise one health: A Sino-Swedish collaboration to tackle antibiotic resistance2016In: One Health, ISSN 2352-7714, ONE HEALTH, Vol. 2, p. 139-143Article in journal (Refereed)
    Abstract [en]

    Antibiotic resistance is a complex global health challenge. The recent Global Action Plan on antimicrobial resistance highlights the importance of adopting One Health approaches that can cross traditional disciplinary boundaries. We report on the early experiences of a multisectoral Sino-Swedish research project that aims to address gaps in our current knowledge and seeks to improve the situation through system-wide interventions. Our research project is investigating antibiotic use and resistance in a rural area of China through a combination of epidemiological, health systems and laboratory investigations. We reflect here on the challenges inherent in conducting long distance cross-disciplinary collaborations, having now completed data and sample collection for a baseline situation analysis. In particular, we recognise the importance of investing in aspects such as effective communication, shared conceptual frameworks and leadership. We suggest that our experiences will be instructive to others planning to develop similar international One Health collaborations. (c) 2016 The Authors. Published by Elsevier B.V.

    Improving Design for Remanufacturing Though Feedback from Remanufacturing to Design2020Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The high demand for products in our society makes manufacturing, and the treatment of products throughout the product life cycle, crucial as it adds to the total environmental impact of a product. Initiatives such as the circular economy promote economic growth while not increasing environmental impacts. The circular economy can also be viewed as a system where the use, maintenance, reuse, remanufacturing, and recycling of materials are optimised to capture the embedded value of products. This doctoral thesis focuses on remanufacturing in particular as an environmentally preferred way to treat products that have reached their end of use. Remanufacturing is an industrial process whereby a used product is restored to its next full life cycle, and thus energy and materials can be saved compared to new production.

    A product that is intended for remanufacturing ought to have certain qualities such as ease of cleaning, ease of separation, and ease of reassembly in order to achieve efficient product remanufacturing. By applying design for remanufacturing (DfRem), costs can be saved as the remanufacturing operation time is reduced. Further, integrating DfRem in the design process is essential in order to achieve a more efficient and effective remanufacturing process. However, the current status in industry is that DfRem is not widely applied, and thus, products are not designed to facilitate remanufacturing. Since DfRem requires knowledge about remanufacturing, feedback from remanufacturing to design is needed for making the correct design considerations. The aim of this doctoral thesis is to expand current knowledge on feedback from remanufacturing to design and how it can be used to improve DfRem.

    Hence, in order to meet the aim of this thesis, both literature studies and multiple case studies were conducted. The case studies include three companies that design, manufacture, and remanufacture their products. The data collection within the case studies was predominantly conducted through semistructured interviews. The results from the case studies have been further explored in a cross-case analysis.

    The literature studies show the potential feedback from remanufacturing to design can be divided into three main categories: from the remanufacturing personnel, related to the process of remanufacturing, or related to the core to be remanufactured. Further, potential feedback at the case companies was found. However, currently, the potential feedback remains unsought for at the case companies. Indeed, there are barriers for feedback from remanufacturing to design, such as lack of knowledge, lack of incentives, and organisational barriers. However, there are also enablers, such as business opportunities to be gained, increased customer willingness, and laws, regulations, and standards encouraging more sustainable products.

    In this doctoral thesis, a framework for improving implementation of DfRem is presented, as the use of DfRem and feedback from remanufacturing to design was found to be scarce in the case companies. The developed Remanufacturing Information Feedback Framework (RIFF) focuses on breaching the barriers for feedback from remanufacturing to design. Further, the application of the RIFF promotes the implementation of DfRem methods and tools, which, when applied, could make remanufacturing more efficient and effective. Consequently, the increased application of DfRem will contribute to the overall growth of the remanufacturing market, which will also reduce the negative environmental impact and promote, in turn a more circular economy.

    Abstract [en]

    A key to sustainable product development is to consider the entire product life-cycle, as well as the requirements on product design in the different life-cycle phases. Improvements in product design can be based on information feedback from the product life-cycle. The aim of this paper is to identify sources of information from the product life-cycle for product design, as well as what benefits the retrieval of such information feedback can have for the product development process. The method udes for this paper was a literature review, utilizing the Scopus and Science Direct databases. Feedback information on the design phase can stream from the product life-cycle phases of manufacturing, use, service and edn-of-life. The feedback includes objective and subjective data from customers, users, service technicians and company staff involved in the product life-cycle. The feedback from the product life-cycle needs to be managed well, and relevant information should be available to the product development team in the design phase. Sucg information flows are valuable in supporting the design of products to facilitate the entire product life-cycle.

    Abstract [en]

    In order to achieve a sustainable development, circular economy approaches and circular material flows are explored in industry. However, circular information flows remain essentially unestablished. The aim of this paper is to: 1) explore categories and types of product life-cycle information available for remanufacturing; 2) identify constraints for efficient product life-cycle information flow via remanufacturing; and 3) propose initiatives to facilitate product life-cycle information flow via remanufacturing.

    Data was collected through workshops and interviews at five remanufacturing companies. An accumulated Sankey diagram illustrates product life-cycle information flow, losses and bottleneck. Based on the analysis, possible initiatives to facilitate efficient product life-cycle information flow via remanufacturing are presented.

    Abstract [en]

    The design of products greatly influences the performance of the product in the rest of the product’s life-cycle phases, e.g. manufacturing, use/maintenance and end-of-life processes. In order to design more sustainable products, information from all life-cycle phases should be implemented in structured ways via e.g. eco-design tools in the design process. Remanufacturing is one viable end-of-life strategy that is environmentally beneficial as it will preserve most of the material and energy put into the initial product and/or its components. Although the product design determines a large portion of the remanufacturability of a product, few companies apply design for remanufacturing on their products.The aim of this paper is to show what type of feedback is available at remanufacturers, and to explore the barriers that prevent that feedback from reaching product development. Using the case study methodology, data have been collected through semi-structured interviews with four remanufacturing companies focusing on the information exchange between the departments of remanufacturing and product development.The case study results show that there is feedback from the remanufacturers concerning a wide variety of design aspects. Furthermore, the remanufacturers have feedback about information they lack from design and the use phase including service. At present, however, there is no feedback provided from remanufacturing to design in the cases studied. Thus, the barriers for providing available life-cycle information feedback are assessed. There are both internal and external barriers. Between design and remanufacturing the barriers include e.g. lack of knowledge and organisational aspects. Further influencing the lack of feedback are managerial aspects such as the business case and specifications lacking remanufacturing aspects and thus not supporting design for remanufacturing. However, design changes such as different joining methods, a higher degree of standardization and different material selections could be very beneficial for remanufacturing and thus the environment.

    Abstract [en]

    With a Product-Service System (PSS), the producer often has control of its products during multiple life-cycles, and thus there are more incentives for design for service and remanufacturing in comparison to traditional sales. The aim of this paper is to explore the role of PSS regarding information feedback transfer in the product life-cycle including remanufacturing. The paper explores two industrial cases where PSS does not yet act as a facilitator for transferring information feedback from remanufacturing to product designers. However, the full potential of PSS is not yet utilized at the companies, and their products are neither designed for PSS nor remanufacturing. (C) 2016 The Authors. Published by Elsevier B.V.

    Abstract [en]

    Company interest and research in the circular economy and remanufacturing have increased as a means of reducing negative environmental impacts. Remanufacturing is an industrial process whereby used products are returned to a state of like-new. However, few products are designed for remanufacturing, and further research and industrial efforts are needed to facilitate more widespread use of design for remanufacturing. One crucial factor facilitating design for remanufacturing is the integration of feedback in the product design process. Thus, the objective of this paper is to analyse feedback flows from remanufacturing to product design. Hence, a literature study and multiple case studies were conducted at three companies that design, manufacture and remanufacture different kinds of products. The cross-case analysis revealed the five barriers of the lack of internal awareness, lack of knowledge, lack of incentives, lack of feedback channels and non-supportive organisational structures, and the five enablers of business opportunities, integrated design processes, customers’ demand, laws, regulations and standards, and new technologies. To establish improved feedback from remanufacturing to product design, the barriers need to be addressed and the enablers explored. Thus, improved feedback from remanufacturing to product design will improve the design of future products suited for a more circular economy.

    2019 (English)In: Journal of Remanufacturing, ISSN 2210-464X, p. 1-20Article in journal (Refereed) Epub ahead of print
    Abstract [en]

    Remanufacturing is an industrial process turning used products into a condition of like new or better. Remanufacturing is also one strategy that salvages the value put into products during manufacturing and thus reduces the environmental impact of products over the life-cycle. However, not many products are designed for remanufacturing, and there is rarely any feedback from remanufacturing to design. Since design for remanufacturing is not applied at most manufacturing companies, there is a need to support companies, for example, by information feedback methods. By implementing feedback transfer from remanufacturing to design and employing design for remanufacturing, the remanufacturing process is more likely to be effective and efficient. The aim of this paper is to present a framework that supports design for remanufacturing by the implementation of structured feedback from remanufacturing to design. The framework aims at strategically outlining and practically implementing information feedback from remanufacturing to design. A case company where the framework has been initialised is also presented.

    Residual Stress Distributions in Additively Manufactured Parts: Effect of Build Orientation2020Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Additive manufacturing (AM) of parts using a layer by layer approach has seen a rapid increase in application for production of net shape or near-net shape complex parts, especially in the field of aerospace, automotive, etc. Due to the superiority of manufacturing complex shapes with ease in comparison to the conventional methods, interest in these kinds of processes has increased. Among various methods in AM, laser powder bed fusion (LPBF) is one of the most widely used techniques to produce metallic components.

    As in all manufacturing processes, residual stress (RS) generation during manufacturing is a relevant issue for the AM process. RS in AM are generated due to a high thermal gradient between subsequent layers. The impact of residual stresses can be significant for the mechanical integrity of the built parts and understanding the generation of RS and the effect of AM process parameters is therefore important for a broader implementation of AM techniques. The work presented in this licentiate thesis aims to investigate the influence of build orientation on the RS distribution in AM parts. For this purpose, L-shaped Inconel 718 parts were printed by LPBF in three different orientations, 0°, 45°, and 90°, respectively. Inconel 718 was selected because it is a superalloy widely used for making gas turbine components. In addition, IN718 has in general good weldability which renders it a good material for additive manufacturing.

    Residual stress distributions in the parts removed from the build plate were measured using neutron diffraction technique. A simple finite element model was developed to predict the residual stresses and the effect of RS relaxation due to the separation of the parts and build plate. The trend of residual stress distribution predicted was in good agreement with experimental results. In general, compressive RS at the part center and tensile RS near the surface were found. However, while the part printed in 0° orientation had the least amount of RS in all three principal directions of part, the part built in 90° orientation possessed the highest amount of RS in both compression and tension. The study has shown that residual stress distributions in the parts are strongly dependent on the building process. Further, it has shown that the relaxation of RS associated with the removal of the parts from the build plate after printing has a great impact on the final distribution of residual stress in the parts. These results can be used as guidelines for choosing the orientations of the part during printing.

    Beslutsstöd för prioriteringar på individnivå: Exempel från hjälpmedelsverksamhet2019Report (Other academic)
    Abstract [en]

    Since 1997, when the ethical platform for resource allocation was introduced in the Swedish health care system, methods have been in development with the aim of supporting the healthcare providers in the difficult decisions of assigning priorities. The methodological focus has been on the major issues, on the allocation of resources at regional level and policy decisions in various activities, but the large number of priorities are made on a daily basis in interactions between health care staff and patients.

    This report is addressed to those who strive to prioritize at individual level on more equal and explicit grounds, in line with the guidelines on priorities that the Riksdag has decided on. The tool presented here is called Decision support for priorities at the individual level. It aims to guide the analysis of the persons´ health care needs so that the need-solidarity and the cost-effectiveness principle are taken into account in the assessment. It is the result of many years of development work and tested in practice in Center for assistive technology in different regions for several years. In addition to being used in prescribing such technology, decision support is also possible to test for other types of health care interventions.

    The decision support consists of an assessment form and a manual. Severity, patient benefit and patient benefit in relation to costs are the variables that should be assessed and direct the health care staff in assigning a priority.

    One aim of using the decision support is to facilitate priorities on more equal grounds. Introduced in a well-organized manner, it can contribute to, but not alone, create such priorities. In order to create mutual understanding and acceptance for grounds and transparency in priorities, a thought-out implementation process is also required. In this report, such an example is given from Region Jönköpings län and prescribers of assistive devices. The main ingredients for succeeding in such work seem to be support from the management and political level, methodological support and constant perseverance.

    Detektion av Anaplasma phagocytophilum och Rickettsia spp. hos Ixodes persulcatus i Norrbotten, Sverige med realtids-PCR2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Detta är den första studien där förekomsten av Anaplasma phagocytophilum och Rickettsia spp. hos Ixodes persulcatus fästingar insamlade från Sverige undersökts. Syftet med denna studie var att undersöka förekomsten av Anaplasma phagocytophilum och Rickettsia spp. hos I. persulcatus i Norrbotten, Sverige.

    Fästingar livnär sig på blod och är vektor för flera olika patogena mikroorganismer. I Sverige är den vanligaste arten Ixodes ricinus men 2016 fann forskare etablerade populationer även av I. persulcatus i norra Sverige. I. persulcatus har bl.a. människa som värddjur och är vektor för bl.a. Anaplasma phagocytophilum och Rickettsia spp.

    Totalt analyserades 292 I. persulcatus fästingar med realtids-PCR med Anaplasma och Rickettsia gltA som målgen. Positiva prover analyserades med konventionell PCR med 17-kDa och ompB som målgener. PCR produkter nukleotidsekvenserades för artbestämning. Resultaten är att prevalensen av A. phagocytophilum är 0 % och prevalensen av Rickettsia spp. är 0.68 % (n=2) vilket är betydligt lägre än i andra länder. Av de två positiva proverna kunde en artbestämmas till R. helvetica och den andra kunde inte artbestämmas.

    De 292 fästingarna har tidigare analyserats för andra patogena mikroorganismer. I jämförelse med andra länder är saminfektionen lägre för dessa fästingar. Kunskap om I. persulcatus utbredningsområde i Sverige och vilka patogena mikroorganismer de är vektor för är av värde för flera olika grupper i samhället, möjligtvis framför allt för vårdpersonal, djurägare och personer som vistas mycket i riskområden.

    The Gambler’s Fallacy and Decision Fatigue in Decision-Making: A Study on Driving License Examiners2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    People make hundreds of decisions every day, at home, at school or at work and that requires mental efforts, which in turn can be depleting. Previous research in behavioral economics has shown that people are not always rational in their decision-making and the decisions they make are not solely based on the case merits or the decision makers' competence. In addition of being affected by the outcome of our previous decisions, people are also affected by the number of decisions they have made in one day, as a result of fatigue.

    The purpose of this paper was to test to what extent decisions made by driving license examiners at the Swedish Transport Administration suffer from decision fatigue and/or the gambler’s fallacy. Previous studies could show that the more decision we make on a day the more tired we get, which makes us revert to the status quo option, in order to simplify the decision-making process, and also that people tend to incorporate previous decisions in their decision-making.

    We analyzed data on 5,870 decisions, made by 50 driving license examiners, during March of 2018. The decisions were analyzed through the use of logistic regression models. Our results showed that driving examiners are affected by decision fatigue but not the gambler’s fallacy. Surprisingly, our results suggest that the driving license examiners are affected by the opposite fallacy, namely the hot hand fallacy, predicting that an examiner is approximately 5% more likely to pass a test-taker if the previous test-taker passed. Furthermore, our models predict that examiners are affected by decision fatigue, and that the results are stronger in the afternoon.

    We could not say with certainty that the examiners use the hot hand fallacy, nor suffer from decision fatigue since our sample cannot be proved to be random.

    The authors of this study suggest that future studies should be conducted in government bodies that handle sequential decisions, in order to help policy-makers improve decision-making.

    Bystander behaviour in peer victimisation: moral disengagement, defender self-efficacy and student-teacher relationship quality2020In: Research Papers in Education, ISSN 0267-1522, E-ISSN 1470-1146Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to examine how different bystander roles in peer victimisation situations relate to moral disengagement, defender self-efficacy, and student-teacher relationship quality. Self-reported survey data were collected from 333 middle and junior high school students (10-15 years of age) from four schools in Sweden. Random intercept model analyses of factor scores revealed that, when witnessing peer victimisation, students high in moral disengagement and low in defender self-efficacy were more inclined to act as reinforcers or outsiders, and that students high in defender self-efficacy and student-teacher relationship quality were more inclined to act as defenders. Furthermore, examining these relationships within and between classes revealed that reinforcer and outsider behaviours were more common among students who, compared to their classmates, were higher in moral disengagement and lower in defender self-efficacy, whereas defending was more common among students who, compared to their classmates, were higher in defender self-efficacy. The results enrich the knowledge of factors related to different bystander behaviours, which has potential implications for prevention and intervention work.

    A brief commentary on discursive psychology and talking to others2020In: Qualitative Research in Psychology, ISSN 1478-0887, E-ISSN 1478-0895Article in journal (Refereed)
    Abstract [en]

    This commentary provides a short reflection on the current status of discursive psychology in a fluctuating academic landscape. It focuses on three points: how discursive psychological research situates itself in relation to other research (both within and outside of psychology), how psychology itself can be respecified as a discipline (rather than only topic areas within psychology), and on the need for further development of methodological aspects and learning resources within discursive psychology. The piece concludes by noting the strengths of discursive psychology as a detailed analytical approach and of the benefits of talking to, and engaging with, other researchers.

    Microdot Accumulation in the Anterior Cornea with Aging - Quantitative Analysis with in Vivo Confocal Microscopy2020In: Current Eye Research, ISSN 0271-3683, E-ISSN 1460-2202Article in journal (Refereed)
    Abstract [en]

    Purpose: Degenerative microdot deposits in healthy and hypoxic corneas are believed to represent lipofuscin-like material aggregation in the stroma. To accurately assess microdot deposits in a clinical setting, we sought to quantify these deposits for the first time using the non-invasive clinical imaging technique of in vivo confocal microscopy (IVCM). Methods: The corneas of 102 healthy subjects aged 15-88 years were examined by IVCM and microdot density was quantified using a 6-point grading scale by two masked, trained examiners. Microdot density was analyzed with respect to age, sex and stromal depth, and inter-eye and inter-observer differences were evaluated. Results: In healthy subjects, microdot density decreased from the anterior to posterior stroma, with the greatest accumulation observed in the most anterior stroma (subepithelial region). In this region, microdot density correlated strongly with age (P amp;lt; .0001), with increased microdot deposition in older subjects (amp;gt;60 years) relative to younger ones (amp;lt;45 years) (P amp;lt; .001). Microdot density between eyes of the same subject was highly correlated (r = 0.92, P amp;lt; .0001), while no association with sex was noted (P amp;gt;= 0.05). The mean inter-observer difference in microdot assessment was 0.62 +/- 0.09 grades, with a high correlation of grading between observers (r = 0.77, P amp;lt; .0001). Conclusions: IVCM can be used to non-invasively quantify microdot deposits in the subepithelial corneal stroma with good inter-observer reproducibility. Microdot assessment may provide a novel means of quantifying age-related or pathologic degeneration of the corneal stroma in a clinical setting.

    A study of guidelines for respiratory tract infections and their references from Swedish GPs: a qualitative analysis2020In: Scandinavian Journal of Primary Health Care, ISSN 0281-3432, E-ISSN 1502-7724, Vol. 38, no 1, p. 83-91Article in journal (Refereed)
    Abstract [en]

    Background: National guidelines are important instruments in reducing inappropriate antibiotic prescriptions. Low adherence to guidelines is an acknowledged problem that needs to be addressed.

    Method: We evaluated established characteristics for guidelines in the guidelines for lower respiratory tract infection, acute otitis media and pharyngotonsillitis in primary care. We studied how doctors used these guidelines by analysing interviews with 29 general practitioners (GPs) in Sweden.

    Results: We found important between-guidelines differences, which we believe affects adherence. The GPs reported persistent preconceptions about diagnosis and treatment, which we believe reduces their adherence to the guidelines.

    Conclusion: To increase adherence, it is important to consider doctors’ preconceptions when creating new guidelines.

    Leptin levels are associated with multiple sclerosis risk2020In: Multiple Sclerosis, ISSN 1352-4585, E-ISSN 1477-0970, article id 1352458520905033Article in journal (Refereed)
    Abstract [en]

    Background: Obesity early in life has been linked to increased risk of developing multiple sclerosis (MS). Leptin and insulin are both associated with obesity, making them suitable candidates for investigating this connection. Objective: To determine if leptin and insulin are risk factors for relapsing-remitting multiple sclerosis (RRMS). Methods: In this nested case-control study using blood samples from Swedish biobanks, we compared concentrations of leptin and insulin in 649 individuals who later developed RRMS with 649 controls matched for biobank, sex, age and date of sampling. Only pre-symptomatically drawn samples from individuals below the age of 40 years were included. Conditional logistic regression was performed on z-scored values to calculate odds ratios (ORs) with 95% confidence intervals (CIs). Results: A 1-unit leptin z-score increase was associated with increased risk of MS in individuals younger than 20 years (OR = 1.4, 95% CI = 1.1-1.9) and in all men (OR = 1.4, 95% CI = 1.0-2.0). In contrast, for women aged 30-39 years, there was a lower risk of MS with increased leptin levels (OR = 0.74, 95% CI = 0.54-1.0) when adjusting for insulin levels. Conclusion: We show that the pro-inflammatory adipokine leptin is a risk factor for MS among young individuals.

    Internet-based CBT for patients with depressive disorders in primary and psychiatric care: Is it effective and does comorbidity affect outcome?2020In: Internet Interventions, ISSN 2214-7829, INTERNET INTERVENTIONS-THE APPLICATION OF INFORMATION TECHNOLOGY IN MENTAL AND BEHAVIOURAL HEALTH, Vol. 19, article id UNSP 100303Article in journal (Refereed)
    Abstract [en]

    Internet-based cognitive behavior therapy (ICBT) has proved effective in reducing mild to moderate depressive symptoms. However, only a few studies have been conducted in a regular healthcare setting which limits the generalizability of the results. The influence of psychiatric comorbidity on outcome is not well understood. In the current study, patients with mild to moderate depressive symptoms in primary and psychiatric care were interviewed using the SCID-I and SCID-II to assess psychiatric diagnoses. Those included were randomly allocated to ICBT (n = 48) or to an active control condition (n = 47). Both groups received therapist support. At post-treatment, ICBT had reduced depressive symptoms on the BDI-II more than the active control intervention (p = .021). However, the difference between groups was no longer significant at the 6-, 12- or 24-month followups. The within-group effect size after ICBT (BDI-II) was large (d = 1.4). A comorbid anxiety disorder didnt moderate the outcome, while the presence of a personality disorder predicted significantly less improvement in depressive symptoms. ICBT had a large effect on depressive symptoms in a sample from regular healthcare. It is possible to obtain a large effect from ICBT despite comorbid anxiety, however, including patients with a comorbid personality disorder in the current form of ICBT seems questionable.

    Lonesome no more?: A two-year follow-up of internet-administered cognitive behavioral therapy for loneliness2020In: Internet Interventions, ISSN 2214-7829, INTERNET INTERVENTIONS-THE APPLICATION OF INFORMATION TECHNOLOGY IN MENTAL AND BEHAVIOURAL HEALTH, Vol. 19, article id 100301Article in journal (Refereed)
    Abstract [en]

    The current study sought to investigate the long-term effects of an internet-administered programme based on CBT principles for which the initial efficacy has been reported in Kall, Jagholm, et al. (In press). Seventy-three participants who were recruited on the basis of experiencing frequent and prolonged loneliness were contacted to complete questionnaires measuring loneliness, quality of life, and symptoms of psychopathology two years after the conclusion of the initial treatment period. Additional items regarding use of the treatment techniques and strategies contained in the programme during the follow-up period was included. In total, 44 participants provided data for the loneliness measure at follow-up. The outcome data were analyzed with a piecewise mixed effects model to provide estimates of change for the continuous measures. Linear multiple regression analysis was used to investigate the relationship between use of treatment techniques and reliable change on the primary outcome measure. The results showed decreases in loneliness during the follow-up period for the sample as a whole. Additionally, an increase in quality of life and a decrease in social anxiety were noted, but no significant changes of depressive symptoms or generalized anxiety. Effect sizes for the observed changes from baseline to follow-up were in the moderate to large range for all measures. Reported use of the treatment techniques was not significantly related to reliable change in loneliness after the two-year period. In conclusion, the results of the study support the utility of internet-based CBT targeting loneliness and indicate that the benefits from the intervention can be enduring.

    Adverse events in psychiatry: a national cohort study in Sweden with a unique psychiatric trigger tool2020In: BMC Psychiatry, ISSN 1471-244X, E-ISSN 1471-244X, BMC PSYCHIATRY, Vol. 20, no 1, article id 44Article in journal (Refereed)
    Abstract [en]

    Background

    The vast majority of patient safety research has focused on somatic health care. Although specific adverse events (AEs) within psychiatric healthcare have been explored, the overall level and nature of AEs is sparsely investigated.

    Methods

    Cohort study using a retrospective record review based on a two-step trigger tool methodology in the charts of randomly selected patients 18 years or older admitted to the psychiatric acute care departments in all Swedish regions from January 1 to June 30, 2017. Hospital care together with corresponding outpatient care were reviewed as a continuum, over a maximum of 3 months. The AEs were categorised according to type, severity and preventability.

    Results

    In total, the medical records of 2552 patients were reviewed. Among the patients, 50.4% were women and 49.6% were men. The median (range) age was 44 (18–97) years for women and 44.5 (18–93) years for men.

    In 438 of the reviewed records, 720 AEs were identified, corresponding to the AEs identified in 17.2% [95% confidence interval, 15.7–18.6] of the records. The majority of AEs resulted in less or moderate harm, and 46.2% were considered preventable. Prolonged disease progression and deliberate self-harm were the most common types of AEs. AEs were significantly more common in women (21.5%) than in men (12.7%) but showed no difference between age groups. Severe or catastrophic harm was found in 2.3% of the records, and the majority affected were women (61%). Triggers pointing at deficient quality of care were found in 78% of the records, with the absence of a treatment plan being the most common.

    Conclusions

    AEs are common in psychiatric care. Aside from further patient safety work, systematic interventions are also warranted to improve the quality of psychiatric care.

    Organic thin film photofaradaic pixels for on-demand electrochemistry in physiological conditions2020In: Chemical Communications, ISSN 1359-7345, E-ISSN 1364-548X, Vol. 56, no 11, p. 1705-1708Article in journal (Refereed)
    Abstract [en]

    We report ultrathin organic photovoltaic elements optimized to run photofaradaic reactions in biological conditions. We demonstrate concurrent oxygen reduction to hydrogen peroxide and glucose oxidation. The devices are powered by deep-red irradiation in the tissue transparency window. We utilize bilayers of phthalocyanine, acting as the light absorber, and perylene diimide, functioning as both electron-acceptor and the hydrogen peroxide evolution electrocatalyst. These heterojunction bilayers are stable when irradiated in simulated physiological conditions, producing photovoltages sufficient to simultaneously drive cathodic oxygen reduction to H2O2 and anodic oxidation of glucose. We find that optimization of the anode metal is critical for sustained photofaradaic reactivity. Our results demonstrate a robust "wet" thin film photovoltaic with potential for physiological applications where localized electrochemical manipulation is desired, in particular the delivery of reactive oxygen species.

    The power in positionings: A Foucauldian approach to knowledge integration processes2020In: Management Learning, ISSN 1350-5076, E-ISSN 1461-7307, p. 1-17Article in journal (Refereed)
    Abstract [en]

    This study explores the role of relational power and discursive positioning in the knowledge integration process of an interdisciplinary project developing a steam turbine. As boundaries are an important focus of study for knowledge integration studies, more engagement is needed to not only map boundary work in the knowledge integration process, but also to acknowledge the role of power in this context. With help of governmentality and positioning theory, we show how power struggles are manifested as boundary work that both reinforces and undermines temporal and domain-specific boundaries. The study concludes that these reinforcements and underminings are central for our understanding of how knowledge integration develops. In addition, the study shed lights on the significance of the co-existence of domination and freedom in the project work. By acknowledging power relations and studying them as they are played out in discursive talk, the study contributes to an increased understanding of the nuances and intricacies of knowledge integration processes.

    Viscosity dynamics and the production of extracellular polymeric substances and soluble microbial products during anaerobic digestion of pulp and paper mill wastewater sludges2020In: Bioprocess and biosystems engineering (Print), ISSN 1615-7591, E-ISSN 1615-7605, Vol. 43, no 2, p. 283-291Article in journal (Refereed)
    Abstract [en]

    The production processes of the pulp and paper industry often run in campaigns, leading to large variations in the composition of wastewaters and waste sludges. During anaerobic digestion (AD) of these wastes, the viscosity or the production of extracellular polymeric substances (EPS) and soluble microbial products (SMP) may be affected, with the risk of foam formation, inefficient digester mixing or poor sludge dewaterability. The aim of this study was to investigate how viscosity and production of EPS and SMP during long-term AD of pulp and paper mill sludge is affected by changes in organic loading rate (OLR) and hydraulic retention time (HRT). Two mesophilic lab-scale continuous stirred tank reactors (CSTRs) were operated for 800 days (R1 and R2), initially digesting only fibre sludge, then co-digesting fibre sludge and activated sludge. The HRT was lowered, followed by an increase in the OLR. Reactor fluids were sampled once a month for rheological characterization and analysis of EPS and SMP. The production of the protein fraction of SMP was positively correlated to the OLR, implicating reduced effluent qualities at high OLR. EPS formation correlated with the magnesium content, and during sulphate deficiency, the production of EPS and SMP increased. At high levels of EPS and SMP, there was an increase in viscosity of the anaerobic sludges, and dewatering efficiency was reduced. In addition, increased viscosity and/or the production of EPS and SMP were important factors in sludge bulking and foam formation in the CSTRs. Sludge bulking was avoided by more frequent stirring.

    Early Adolescents Emotional and Behavioral Difficulties, Student-Teacher Relationships, and Motivation to Defend in Bullying Incidents2020In: Child and Youth Care Forum, ISSN 1053-1890, E-ISSN 1573-3319, Vol. 49, no 1, p. 59-75Article in journal (Refereed)
    Abstract [en]

    Background School bullying is a widespread phenomenon across the world, which involves bystanders who take on various roles. Motivation to defend victims is important to investigate because it helps us devise better, evidence-based, anti-bullying interventions. Objective We aimed to determine whether students behavioral and emotional strengths and difficulties and student-teacher relationships were associated with different types of motivation to defend victims of bullying. The hypotheses were (1) emotional and behavioral difficulties will be associated with less autonomous and introjected motivation to defend and greater extrinsic motivation to defend and (2) close student-teacher relationships will be associated with greater autonomous motivation to defend, and less extrinsic motivation to defend. Method Data were collected from 483 Swedish early adolescents who completed a survey in their classrooms. Results Results showed that, among boys and girls, close student-teacher relationships were positively associated with autonomous motivation and negatively associated with extrinsic motivation to defend, while negative expectations concerning teachers were associated with all forms of motivation to defend. Emotional and behavioral difficulties were only associated with introjected motivation to defend among girls. Furthermore, extrinsic motivation to defend was associated with the interactions between individual differences in behavioral and emotional difficulties and negative expectations. Conclusions Adolescents who are more occupied with wanting to have a better relationship with their teachers might be motivated to be involved in good social relationships with others. The results also indicate that closeness in student-teacher relationships is important for greater autonomous motivation to defend victims during bullying.

    Using smartphone logging to gain insight about phone use in traffic2020In: Cognition, Technology & Work, ISSN 1435-5558, E-ISSN 1435-5566, Vol. 22, no 1, p. 181-191Article in journal (Refereed)
    Abstract [en]

    The prevalence of mobile phone usage in traffic has been studied by road-side counting, naturalistic driving data, surveillance cameras, smartphone logging, and subjective estimates via surveys. Here, we describe a custom-made smartphone logging application along with suggestions on how future such applications should be designed. The developed application logs start and end times of all phone interactions (mobile phone applications, incoming/outgoing phone calls and text messages, audio output, and screen activations). In addition, all movements are automatically classified into transport, cycling, walking, running, or stationary. The capabilities of the approach are demonstrated in a pilot study with 143 participants. Examples of results that can be gained from smartphone logging include prevalence in different transportation modes (here found to be 12% while driving, 4% while cycling, and 7% while walking), which apps are being used (here found to be 19% navigation, 12% talking, 12% social media, and 10% games) and on which road types (rural, urban, highway etc.). Smartphone logging was found to be an insightful complement to the other methods for assessing phone use in traffic, especially since it allows the analyses of which apps are used and where they are used, split into transportation mode and road type, all at a relatively low cost.

    Genetic polymorphism patterns suggest a genetic driven inflammatory response as pathogenesis in appendicitis2020In: International Journal of Colorectal Disease, ISSN 0179-1958, E-ISSN 1432-1262, Vol. 35, no 2, p. 277-284Article in journal (Refereed)
    Abstract [en]

    Purpose The pathogenesis of appendicitis is not well understood. Environmental factors are regarded most important, but epidemiologic findings suggest a role of inflammatory and genetic mechanisms. This study determines the association of single nucleotide polymorphisms (SNPs) of inflammatory genes with appendicitis. Methods As part of a larger prospective study on the diagnostic value of inflammatory variables in appendicitis, the genotype frequency of 28 polymorphisms in 26 inflammatory response genes from the appendicitis and control patients was analyzed in blood samples from 343 patients, 100 with appendicitis, and 243 with non-specific abdominal pain, using TaqMan SNP genotyping assays. Results Associations with appendicitis were found for SNPs IL-13 rs1800925 with odds ratio (OR) 6.02 (95% CI 1.52-23.78) for T/T versus C/C + T/T, for IL-17 rs2275913 with OR 2.38 (CI 1.24-4.57) for A/A vs G/G + GA, for CCL22 rs223888 with OR 0.12 (0.02-0.90), and for A/A vs G/G + GA. Signs of effect modification of age for the association with appendicitis were found for IL-13 rs1800925 and CTLA4 rs3087243. Stratified analysis showed difference in association with severity of disease for IL-17 rs2275913 and CD44 rs187115. Conclusions The association of gene variants on risk of appendicitis and its severity suggest an etiologic role of genetically regulated inflammatory response. This may have implications for understanding the prognosis of untreated appendicitis as a possible self-limiting disorder and for understanding the inverse association of appendicitis with ulcerative colitis.
