    Könsnormer, samhällsnormer och gymnasievalet: En kvalitativ studie med tre pojkar från det estetiska programmet bild och formgivning2018Independent thesis Basic level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Denna studies syfte är att ta reda på och utveckla kunskap om könsnormer om maskulinitet och andra normer som kan ha en verkan på pojkars gymnasieval till det estetiska programmets inriktning bild och formgivning. För att få reda på detta används intervjumetoden halv-strukturerad intervju tillsammans med en arrangerad fokusgrupp. Fokusgruppen utgör en homogen grupp av tre pojkar i det estetiska programmets bild och formgivning.

     

    Resultatet samt analysen och diskussionen av intervjun ger läsarna en inblick i vad pojkarna i intervjun har för upplevelser i att gå det estetiska programmet bild och formgivning. Pojkarna som deltar i studien bär på förstahandsinformation om möten de har haft med elever på skolans andra program samt människor utanför skolmiljön. Genom dessa möten blir pojkarna i studien utsatta för olika normer, könsnormer och maskuliniteter som finns i samhället men som de väljer att avvika från. Pojkarna i studien ställer sig mot maskulina könsnormer i deras samhälle som att bild är ett intresse för flickor samt att pojkar förväntas gå gymnasieprogram som säkrar framtida yrken med bra lön.

    Filmaffischer och genus: En kvalitativ studie om hur produktionsbolaget Marvel framställer sina karaktärer på filmaffischer2016Independent thesis Basic level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie är att undersöka hur produktionsbolaget Marvel framställer sina karaktärer på filmaffischer ur ett genusperspektiv. Detta eftersom att Marvel fått kritik för hur de porträtterar kvinnliga superhjältar. Syftet är också att genom egna gestaltningar undersöka superhjältarnas utformning. För att uppnå detta har studien använts sig av en kvalitativ metod och med teorier som hermeneutik, semiotik och genus. Analysen har valt ut fem stycken filmaffischer från Marvel för att undersöka hur män och kvinnor porträtterades på affischerna och hur maktförhållanden yttrar sig på affischerna. Resultatet av undersökningen är att männen ofta porträtteras som starka, målinriktade och handlingskraftiga och kvinnorna antingen framstår som svaga och passiva eller att de objektifieras. Studien innehåller även en egen gestaltning där superhjältars utformning undersöks i illustrationer.

    Utrymme för tredimensionellt skapande: En studie av fördelningen mellan tvådimensionellt och tredimensionellt bildarbete2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med studien har varit att att undersöka faktorer som påverkar fördelningen mellan tvådimensionellt och tredimensionellt bildarbete i grundskolans senare år. Syftet har studerats genom frågeställningarna: Hur motiveras fördelningen av två-och tredimensionell bild i kursplanen sett över tid?, Hur beskriver bildlärare sin tredimensionella bildundervisning?, Vilka möjligheter och hinder upplever bildlärare med tredimensionellt bildarbete? och Som metod för studien användes kvalitativ semistrukturerad intervju. Tre bildlärare i grundskolans senare år intervjuades. En dokumentanalys har genomförts och kursplaner i ämnet teckning/ bild från 1962 till 2011 har studerats. Ramfaktorteori har använts för att analysera materialet. I arbetets bakgrund har det uttryckts att tredimensionellt undervisning som skett med kropp och händer varit fördelaktigt för lärande. Bildundervisningen är dock övervägande tvådimensionell i sin utformning. Kropp och rum har ibland glömts bort i bildundervisningen. Den tvådimensionella representationens ställning har tagit allt mer mark och likväl har teoretisk kunskap fått mer utrymme än praktiskt kunskap. Resultat i studien har visat att faktorer på organisations- och verksamhetsnivå är mer fördelaktiga för tvådimensionell bildundervisning. Nuvarande läroplan är öppen för tolkning vad det gäller hur tid fördelas mellan olika kunskaper. Bildlärarens intresse har fått utrymme att styra inriktningen för undervisningen, likväl har gruppstorlek och längd på lektioner styrt vilken typ av undervisning som är möjlig

    Bedömning i bild: En kvalitativ studie om ett komplext arbete2018Independent thesis Basic level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Denna studie syftar till att ge inblick i det område som rör bedömning i bildämnet, samt synliggöra verksamma bildlärares bedömningspraktik och förhållningssätt till bedömning och likvärdighet. Trots att det finns problematiska aspekter med bedömningen i bild är forskning i området bristfällig. I denna studie besvaras därför frågor om hur ett bedömningsarbete i bild kan se ut, vilken problematik lärarna ställs inför i bedömningssituationer, samt hur likvärdighet kan uppnås i bildämnet. Detta med hjälp av kvalitativa intervjuer med verksamma bildlärare på både grundskolan och gymnasiet. Resultatet visar på både likheter och skillnader i bedömningspraktiken, samt att arbetet är utmanande och komplext. Detta förklaras bland annat av det fria tolkningsutrymmet som läroplanen öppnar upp för, att konstnärliga och praktiska kunskaper är svåra att sätta ord på, samt att lärarna förhåller sig olika till ett kollegialt samarbete.

    Att synliggöra Bildämnet för elever inom autismspektrum: Om att tillämpa estetiska läroprocesser och visuella hjälpmedel vid undervisning i ämnet Bild2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Studiens syfte har varit att undersöka hur de estetiska läroprocesserna tillämpas av bildlärare i bildundervisningen för elever inom autismspektrum. Centrala frågor för studien har varit vilka metoder/strategier bildlärare använder för att hjälpa elever inom autismspektrum med att skapa bilder som kommunicerar erfarenheter, åsikter och upplevelser. Men även frågor om vilka lärandesituationer som främjar kunskapsinhämtning och på vilket sätt som bildlärare återkopplar till eleverna inom autismspektrum har tagits upp i denna studie. Studiens viktigaste resultat är att lärarna använder estetiska läroprocesser för att förtydliga och skapa struktur i undervisningen samt att lärarna använder olika visuella hjälpmedel för att hjälpa elever inom autismspektrum vid undervisning av ämnet Bild. Det har också framkommit i studien att lärarna återkopplar muntligt, instruerande, textbaserat och bildbaserat. Återkoppling till elever inom autismspektrum sker på samma sätt som till elever utan diagnos men den bildbaserade och textbaserade återkopplingen ansågs vara mer tydlig. I studien framkommer det att lärandesituationer som främjar kunskapsinhämtning i ämnet Bild för målgruppen bygger på tydlighet, begränsad valmöjlighet, visuellt stöd samt att utgå från elevernas specialintressen. Studien bygger på halvstrukturerade intervjuer och empirin har analyserats utifrån Lars Lindströms modell för estetiska lärprocesser OM, I, GENOM och MED-konst.

    Slöjd - ett gemensamt ämne?: En studie av ramfaktorers inverkan på slöjdens organisation.2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Ämnet slöjd skrivs fram som ett gemensamt ämne enligt den nu gällande läroplan, men som i praktiken är uppdelad i två slöjdinriktningar. Traditionens makt är stor över hur slöjdundervisningen skall mötas och bearbetas. Syftet med studien har varit att undersöka hur slöjdlärare arbetar vid högstadieskolor som i organisationen av slöjdämnet suddat ut gränserna mellan materialinriktningarna textilslöjd och trä- och metallslöjd. Syftet har studerats genom frågeställningarna: Hur beskriver lärare att det kollegiala samarbetet fungerar i det gemensamma slöjdämnet i relation till planering, undervisning och bedömning? Vilka ramfaktorer styr detta samarbete och hur inverkar det organisatoriskt på utformandet av det gemensamma slöjdämnet? Studiens empiri har sin grund i kvalitativa intervjuer av sex slöjdlärare som arbetar med slöjd som ett ämne. Det kollegiala samarbetet och slöjdundervisningen påverkas organisatoriskt av olika ramfaktorer, påverkas både positivt och negativt. Slöjdlärarna har beskrivit olika faktorer och situationer i sitt samarbete som har gjort att de befinner sig där de är med sitt kollegiala samarbete. Resultatet i studien har visat att ramfaktorer som tid har en stor inverkan på samarbete mellan slöjdlärarna, påverkan på hur lärarnas schemapositioner och gemensamma planeringstid ser ut. Samt påverkan på faktorer som hur stora elevgrupper man möter och slöjdsalarnas placering i förhållande till varandra.

    Managerial Perceptions of Scope Creep in Projects: A Multiple-Case Study2018Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction - Scope creep is uncontrolled and unauthorized changes to a project, extending the project beyond its initial boundaries. An extensive literature review indicated that scope creep is a common occurrence in projects with dire consequences. There are two dominant perspectives on scope creep. Either it is preventable, or inevitable. Based on these findings, the author seeks to investigate the phenomena by answering the research question of this thesis: Why do project managers have opposing perceptions of scope creep in projects?

    Purpose - This paper explores the managerial perceptions on the two opposing viewpoints on scope creep and potential variations. No previous studies investigate the phenomena in a matter of perception. The paper aims to open new insights about how project managers perceive scope creep based on their own experiences through project management in practice.

    Design/methodology/approach - The thesis employs a multiple, cross-sectional and mono-method case study design. A qualitative research method is utilized in combination with interpretative and inductive approaches. Sampling criteria techniques used are purposive and snowballing, focusing on project managers in Norway. Five project managers were interviewed in-depth following an interview guide facilitating semi- structured interviews. The interviews were later translated, transcribed and categorized in a thematic analysis template.

    Findings - The study’s findings indicate that the opposing managerial perspectives on scope creep are due to a varying degree of knowledge on the phenomena and its definition. Low comprehension of scope creep in project management teams generates ambiguity and uncertainty. Insufficient awareness of scope creep inclines project members to misuse the term, resulting in an inability to detect or discern scope creep from formalized changes to the project scope. The academic debate concerns whether scope creep is preventable or inevitable. This study found that the academic discrepancy is owed to a dissonance between academic project management literature and the real-world experiences from practicing project managers.

    Research limitations/implications - The paper is limited by investigating scope creep based only on data collected from Norwegian nationals. Furthermore, the sample size of the case study is relatively small. These limitations might inhibit the generalization of findings.

    Practical implication - The following findings and results aids practicing project managers by highlighting the importance of a clear definition of scope creep. Awareness of scope creep assists project team members to discover unauthorized changes, resulting in proper communication within the project management team concerning rogue changes.

    Originality/value - The paper examines experienced project managers different perspectives of scope creep from practical applications in the project management field.

    Kod 9: En interventionsstudie med intensiv, upprepad parläsning i helklass2019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The aim of the study was to investigate if an intensive, repeated, paired reading intervention consisting of three minutes of reading three times a day could improve student decoding skills of all students, including those in language difficulty. In 2016, Hylén Landström showed that a reading intervention of two minutes twice a day did not result in an improvement in student decoding skills. Following Hylén Landström, the students in the present study read in pairs for three minutes each, three times a day for six weeks. Thus, the students read for five minutes more each day than the students in Hylén Landström’s study. The results show an improvement in decoding skills for most students after the intervention. To assess the sustainability of teaching method, the students completed questionnaires and teachers participated in interviews. All the students were positive to the method, and all teachers saw the benefits of the teaching and learning approach. Clear classroom routines surrounding the method are necessary for maximum sustainability. In sum, by increasing the length and number of reading sessions per day produced improvements in decoding skills, particularly for younger students, those in difficulty, and second language speakers.

    Bildterapeuters arbete med barn och tonåringar som flytt till Sverige: En intervjuundersökning2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Aims: To, by means of a qualitative study assess how art therapists work with children below the age of 18 that has taken refuge to Sweden.

    Methods: Five semi-structured interviews with educated art therapists were conducted and analysed by using a qualitative subject analysis. The triangular model of communication and the concepts of "art as therapy" and "art in psychotherapy" were used as theoretical frames of reference.

    Results: The art therapists create a feeling of security and predictability through group-work, themed exercises and a recurring structure. Both closed and open therapy groups occur.

    Communication between client and therapist can be difficult. Some art therapists rely on non-verbal communication, body language and the artwork, while others use an interpreter. The art therapists work with "art as therapy", focusing on the communication between artwork and client, as well as "art in psychotherapy" with emphasis on therapist/client communication.

    Some therapist actively seek knowledge about the clients’ culture of origin and what their current situation is like, while others let the client express it through the artwork. All therapists approach each client individually even though they work in a group.

    Conclusion: The art therapists adapt their approach to the needs of the individual client, in the moment and over time. When the art therapist applies the concept of "art as therapy" the communication is mostly non-verbal, while "art in psychotherapy" emphasizes verbal communication. Thus, "art as therapy" as well as "art in psychotherapy" can be applied simultaneously in the same client group.

    Agile development in the video game industry: Examining the effects of iteration and methods of limiting it2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This research is examining one of the most dominant managerial methods used in development in the video game industry, Agile development. More particularly, the thesis examines a certain attribute of Agile development, that of iteration. The thesis will set to examine how iteration affects several layers of development during the production of a video game and whether it can be replaced by other managerial technics.As a result, the purpose of this thesis is to raise a different viewpoint against the Agile’s iteration. Furthermore, this thesis aims to contribute to the academic research by concentrating on the video game industry, an industry that is often neglected by the academia.The theoretical framework and literature review concentrate on concepts of Agile development, overworking, development cycle in video games, definitions of project success and project failures and creative process in video game development.The thesis deploys qualitative methodology to address and research its data. The collected data belongs to two categories, data stemming from interviews conducted by the thesis’s author and data stemming from journalistic magazines.The results of both type of data are compared and act supplementary to each other, then they are analyzed to answer the research questions asked by this thesis. The results showcase that iteration has negative effects to video game developers in both a macroscale (company’s resources, annual revenue) and in a microscale (overworking, health issues) level. The results also highlight that Agile is an all-time favorite development methodology of developers in the video game industry.In conclusion, the thesis supports the notion that iteration should be suppressed and proposes a number of solutions for that matter. The suggestions are essentially encouragement towards developers: to seek higher interactivity with customers throughout the duration of all the development stages of a video game, to show more trust to established gameplay mechanics and to place more reliance on a franchise’s profit power and benefits. These measures can be used in a preventive manner in order to limit the appearance of iteration and as a result, to limit its’ negative effects.

    "Bolagets bästa, och sånt": En fallstudie kring kommunala bolagsstyrelseledamöter2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I denna fallstudie undersöks hur politikerna i bolagsstyrelserna för Bostaden och Umeå Energi ser på sin roll i styrelsen, styrelsens roll samt bolagets roll. Semistrukturerade intervjuer användes för att samla in empiri från åtta respondenter, fyra styrelseledamöter från varje bolag. För att tolka detta använder jag mig av teorier som grundar sig i ’lämpligt beteende’ och ’socialisation’ och deras påverkan på aktörer och organisationer. För att analysera empirin så används en form av idealtyper för att jämföra analysenheterna. Det som studien kommer fram till är att det råder en skillnad mellan styrelserna hur styrelseledamöterna ser sin roll i styrelsen samt att det existerar ett brett spektrum av åsikter i vad styrelseledamöterna ser som styrelsens och bolagets roll. Detta genom att ledamöterna sitter på personligt mandat i bolagsstyrelsen och inte behöver förankring i sitt parti. Det gör även att styrelseledamöterna tänker på bolaget i första hand och på bolagets bästa. Det är inom bolagets bästa som skillnaderna mellan ledamöterna märks då de har olika uppfattningar om vad som är bolagets bästa. Förklaringar till detta kan vara att styrelseledamöternas ”ideologiska kompass” påverkar deras uppfattning om bolagets bästa. De skillnaderna som uppkommer mellan bolagsstyrelserna har uppstått genom att ’lämpligt beteende’ och ’socialisation’ har utvecklats under olika lång tid.

    ”Jag hoppas få vara er livmoder”: En multimodal analys av surrogatmödraskap i scener ur The Handmaid’s tale och Vänner2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Title: “I hope to be your uterus” - A multimodal analysis on surrogacy in scenes from The Handmaid’s tale and Friends

    Surrogacy is a widely discussed subject both internationally and in Sweden. The opinions on whether it should be legalized or not differ from country to country, which is reflected in how they implement their different laws on the subject. The main issues in the debates about surrogacy is whether a legalization of altruistic surrogacy would lead to safe methods within the medical care and stop the expansion of illegal markets or if there’s risks of opening the doors to a bigger commercial market. Parallel to the political discussion and opinions on the subject, the portrayal of surrogacy has appeared within popular culture, as in TV-series, for a period of time. It can be found in different genres like drama and comedy since the 90s, which makes the subject interesting to observe.

    The purpose of this essay is to study how the topic of surrogacy is portrayed in two different genres in the TV-series Friends and The Handmaid’s tale. For this purpose we use multimodal analysis to answer if there are similarities and/or differences in the portrayal of surrogacy within our research material. The theoretical framework is based on Richard Dyers theories on stereotypes, Carol Patemans ideas of ‘the sexual contract’ and Brooke Weihe Edges studies on the representation of women in different movie genres amongst others. Our study shows that even if the genres vary there are stereotypical structures in how both infertile women and surrogate mothers are presented to the audience.

    Associations between repeated measure of plasma perfluoroalkyl substances and cardiometabolic risk factors2019In: Environment International, ISSN 0160-4120, E-ISSN 1873-6750, Vol. 124, p. 58-65Article in journal (Refereed)
    Abstract [en]

    Background: Perfluoroalkyl substances (PFAS) are persistent synthetic chemicals that may affect components of metabolic risk through the peroxisome proliferator-activated receptor but epidemiological data remain scarce and inconsistent.

    Objective: To estimate associations between repeated measurements of the main PFAS in plasma and total cholesterol, triglycerides and hypertension among the control subjects from a population-based nested case-control study on diabetes type 2 in middle-aged women and men.

    Methods: Participants (n = 187) were free of diabetes at both baseline and follow-up visits to the Västerbotten Intervention Programme, 10 years apart: during 1990 to 2003 (baseline) and 2001 to 2013 (follow-up). Participants left blood samples, completed questionnaires on diet and lifestyle factors, and underwent medical examinations, including measurement of blood pressure. PFAS and lipids were later determined in stored plasma samples. Associations for the repeated measurements were assessed using generalized estimating equations.

    Results: Six PFAS exceeded the limit of quantitation. Repeated measures of PFAS in plasma, cardiometabolic risk factors and confounders, showed an average decrease of triglycerides from −0.16 mmol/l (95% confidence interval [CI]: −0.33, 0.02 for PFOA) to −0.26 mmol/l (95% CI: −0.50, −0.08 for PFOS), when comparing the highest tertile of PFAS plasma levels with the lowest. Associations based on average PFAS measurements and follow-up triglycerides revealed similar inverse associations, although attenuated. The estimates for cholesterol and hypertension were inconsistent and with few exception non-significant.

    Conclusions: This study found inverse associations between PFAS and triglycerides, but did not support any clear link with either cholesterol or hypertension.

    Perfluoroalkyl substances and risk of type II diabetes: A prospective nested case-control study2019In: Environment International, ISSN 0160-4120, E-ISSN 1873-6750, Vol. 123, p. 390-398Article in journal (Refereed)
    Abstract [en]

    Background: Perfluoroalkyl substances (PFAS) have drawn much attention due to bioaccumulation potential and their current omnipresence in human blood. We assessed whether plasma PFAS, suspected to induce endocrine-disrupting effects, were prospectively associated with clinical type 2 diabetes (T2D) risk.

    Methods: We established a nested case-control study within the Swedish prospective population-based Västerbotten Intervention Programme cohort. Several PFAS were measured in plasma from a subset of 124 case-control pairs at baseline (during 1990–2003) and at 10-year follow-up. T2D cases were matched (1:1) according to gender, age and sample date with participants without T2D (controls).

    Conditional logistic regressions were used to prospectively assess risk of T2D by baseline PFAS plasma concentrations. Associations between long-term PFAS plasma levels (mean of baseline and follow-up) and insulin resistance (HOMA2-IR) and beta-cell function (HOMA2-B%) at follow-up were prospectively explored among 178 and 181 controls, respectively, by multivariable linear regressions.

    Results: After adjusting for gender, age, sample year, diet and body mass index, the odds ratio of T2D for the sum of PFAS (Σ z-score PFAS) was 0.52 (95% confidence interval, CI: 0.20, 1.36), comparing third with first tertile; and 0.92 (95% CI: 0.84, 1.00) per one standard deviation increment of sum of log-transformed PFAS. Among the controls, the adjusted β of HOMA2-IR and HOMA-B% for the sum of PFAS were −0.26 (95% CI: −0.52, −0.01) and −9.61 (95% CI: −22.60, 3.39) respectively comparing third with first tertile.

    Conclusions: This prospective nested case-control study yielded overall inverse associations between individual PFAS and risk of T2D, although mostly non-significant. Among participants without T2D, long-term PFAS exposure was prospectively associated with lower insulin resistance.

    Svenska Hedgefonders Avkastning: En kvantitativ studie om svenska hedgefonders stil, risk och prestation2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Hedgefonder är ett investeringsalternativ som blir allt mer lättillgängligt för den genomsnittliga investeraren. Som ett resultat av detta har nyinvesteringar i hedgefonder ökat avsevärt fram tills idag både bland institutionella och privata sparare. Hedgefonder har kommit att bli ett enormt debatterat ämne i finansbranschen, där stark kritik har riktats mot hedgefondernas förmåga att skapa överavkastning mot marknaden. De flesta som är insatta i den finansiella marknaden känner med säkerhet till Warren Buffets vad mot Ted Seides, där han slog vad om 1 000 000 dollar om att hedgefonderna under den kommande tioårsperioden inte skulle kunna slå S&P 500 i termer av avkastning. Buffet vann vadet och hedgefonderna har haft en av sina tuffaste perioder någonsin.Hedgefonder är också ett ämne som intresserat den akademiska världen väldigt mycket. Det har tidigare genomförts flertalet studier på hedgefonder, dess avkastning och dess investeringsstilar. Konsensus verkar dock inte komma överens kring frågan huruvida hedgefonder klarar av att prestera bättre än marknaden och kring huruvida de faktiskt har lägre eller högre risk än marknaden. I studien har vi bidragit till denna forskning genom att undersöka om svenska hedgefonder klarar av att slå marknaden, OMXS30, både i termer av absolut avkastning och riskjusterad avkastning. Vidare har vi genomfört en stilanalys av hedgefonderna och avslutningsvis också en enklare riskanalys där vi kollat på standardavvikelse, betavärde och Value at Risk.Studien genomförs på ett viktat hedgefondindex, baserat på data över 15 fond-i-fond-hedgefonder inhämtat från Hedgenordic. Datat som använts sträcker sig över perioden 2013-08-31 till 2018-10-31 och är månatlig avkastning. Studien finner inget stöd för att hedgefonder klarar av att generera en absolutavkastning som är högre än OMXS30, däremot finner vi stöd för att man klarar av att generera en högre riskjusterad avkastning. Vidare visar vi att hedgefonderna har varit en mindre riskfylld investering med en lägre standardavvikelse, ett betavärde på mindre än ett och en lägre Value at Risk. Avslutningsvis visar vi att hedgefonder har varit tungt investerade i räntor under tidsperioden, där 47,97 % av kapitalet har investerats i svenska hypoteksräntor och 37,99 % av kapitalet har investerats i svensk statslåneränta.

    Being a student is a crucial investment for future work opportunities, but it is also related to increased levels of stress with risk for anxiety and depression. The main aim of this study is to explore if self-esteem has a relation with students´ levels of stress, anxiety and depression, even after controlling for demographic data. The secondary aim is to investigate if differences in depression, anxiety, stress and self-esteem, are related to various fields of study. Participants consisted of university students (N= 514) from three different fields of study: Computer Science and Information Technology, Health care, and Culture, Media & Design. Three validated instruments were used to examine: Self-esteem (Rosenberg Self-esteem Scale, RSES), Stress, (Perceived Stress Scale, PSS) and Anxiety and Depression (Hospital Anxiety and Stress Scale, HADS). The result from three multiple hierarchical regression analyses shoved that low self-esteem had a strong relation to higher levels of anxiety, stress and depression, in the whole sample.The result from a MANOVA showed that there was a statistically significant difference in stress and mental health according to field of study. The Group of Culture, Media & Design had statistically significantly higher degrees of stress and anxiety than the groups for Computer Science and Health care. There was no statistically significant difference in depression related to field of study. The group of Computer Science had statistically significantly higher self-esteem than the group for Culture, Media & Design. This paper shows that mental illness is common among students and especially among students of Culture, Media & Design. It is therefore important to prevent mental illness and to improve the wellbeing of students.

    The role of PIP5K1 alpha/pAKT and targeted inhibition of growth of subtypes of breast cancer using PIP5K1 alpha inhibitor2019In: Oncogene, ISSN 0950-9232, E-ISSN 1476-5594, Vol. 38, no 3, p. 375-389Article in journal (Refereed)
    Abstract [en]

    Despite recent improvement in adjuvant therapies, triple-negative, and ER+ subtypes of breast cancer (BC) with metastatic potentials remain the leading cause of BC-related deaths. We investigated the role of phosphatidylinositol-4-phosphate 5-kinase alpha (PIP5Kα), a key upstream factor of PI3K/AKT, and the therapeutic effect of PIP5Kα inhibitor on subtypes of BC. The clinical importance of PIP5K1α and its association with survivals were analyzed using three BC cohorts from Nottingham (n = 913), KM plotter (n = 112) and TCGA (n = 817). Targeted overexpression or knockdown of PIP5K1α were introduced into BC cell lines. The effects of PIP5K1α and its inhibitor on growth and invasion of BC were confirmed by using in vitro assays including proliferation, migration, apoptosis and luciferase reporter assays and in vivo xenograft mouse models. All statistical tests were two-sided. PIP5K1α was associated with poor patient outcome in triple-negative BC (for PIP5K1α protein, p = 0.011 and for mRNA expression, p = 0.028, log-rank test). 29% of triple-negative BC had PIP5K1A gene amplification. Elevated level of PIP5K1α increased expression of pSer-473 AKT (p < 0.001) and invasiveness of triple-negative MDA-MB-231 cells (p < 0.001). Conversely, inhibition of PIP5K1α using its inhibitor ISA-2011B, or via knockdown suppressed growth and invasiveness of MDA-MB-231 xenografts (mean vehicle-treated controls = 2160 mm3, and mean ISA-2011B-treated = 600 mm3, p < 0.001). ISA-2011B-treatment reduced expression of pSer-473 AKT (p < 0.001) and its downstream effectors including cyclin D1, VEGF and its receptors, VEGFR1 and VEGFR2 (p < 0.001) in xenograft tumors. In ER+ cancer cells, PIP5K1α acted on pSer-473 AKT, and was in complexes with VEGFR2, serving as co-factor of ER-alpha to regulate activities of target genes including cyclin D1 and CDK1. Our study suggests that our developed PIP5K1α inhibitor has a great potential on refining targeted therapeutics for treatment of triple-negative and ER+ BC with abnormal PI3K/AKT pathways.

    DNA methylation associates with survival in non-metastatic clear cell renal cell carcinoma2019In: BMC Cancer, ISSN 1471-2407, E-ISSN 1471-2407, Vol. 19, article id 65Article in journal (Refereed)
    Abstract [en]

    Background: Clear cell renal cell carcinoma (ccRCC) is the most common subtype among renal cancer and is associated with poor prognosis if metastasized. Up to one third of patients with local disease at diagnosis will develop metastasis after nephrectomy, and there is a need for new molecular markers to identify patients with high risk of tumor progression. In the present study, we performed genome-wide promoter DNA methylation analysis at diagnosis to identify DNA methylation profiles associated with risk for progress.

    Method: Diagnostic tissue samples from 115 ccRCC patients were analysed by Illumina HumanMethylation450K arrays and methylation status of 155,931 promoter associated CpGs were related to genetic aberrations, gene expression and clinicopathological parameters.

    Results: The ccRCC samples separated into two clusters (cluster A/B) based on genome-wide promoter methylation status. The samples in these clusters differed in tumor diameter (p < 0.001), TNM stage (p < 0.001), morphological grade (p < 0.001), and patients outcome (5 year cancer specific survival (pCSS5yr) p < 0.001 and cumulative incidence of progress (pCIP5yr) p < 0.001. An integrated genomic and epigenomic analysis in the ccRCCs, revealed significant correlations between the total number of genetic aberrations and total number of hypermethylated CpGs (R = 0.435, p < 0.001), and predicted mitotic age (R = 0.407, p < 0.001). We identified a promoter methylation classifier (PMC) panel consisting of 172 differently methylated CpGs accompanying progress of disease. Classifying non-metastatic patients using the PMC panel showed that PMC high tumors had a worse prognosis compared with the PMC low tumors (pCIP5yr 38% vs. 8%, p = 0.001), which was confirmed in non-metastatic ccRCCs in the publically available TCGA-KIRC dataset (pCIP5yr 39% vs. 16%, p < 0.001).

    Conclusion: DNA methylation analysis at diagnosis in ccRCC has the potential to improve outcome-prediction in non-metastatic patients at diagnosis.

    Negative Association Between Allopregnanolone and Cerebral Serotonin Transporter Binding in Healthy Women of Fertile Age2019In: Frontiers in Psychology, ISSN 1664-1078, E-ISSN 1664-1078, Vol. 9, article id 2767Article in journal (Refereed)
    Abstract [en]

    Allopregnanolone is a metabolite of the sex hormone progesterone, with suggested relevance for female mood disorders. While allopregnanolone and serotonin are known to influence psychological well-being, the molecular and psychological specifics of their relationship are to date poorly understood, especially in women of fertile age who experience regular fluctuations of progesterone across the menstrual cycle. Availability of serotonin in the synaptic cleft is regulated by the serotonin transporter (SERT), which can be imaged in the living human brain by use of positron emission tomography (PET) and the radiotracer [C-11]DASB. To evaluate sex-specific allopregnanolone-SERT interactions, the present study investigated the relationship between cerebral SERT availability, serum allopregnanolone levels and psychological well-being in women of fertile age. Brain imaging data, self-reported symptoms of mental distress and emotion regulation, and biobank material from ninety healthy women were available from the Center for Integrated Molecular Brain Imaging (CIMBI) database. Age, BMI, and daylight minutes were included as covariates in the analyses and SERT genotype (5-HTTLPR) was considered a potential confounder. Lower serum allopregnanolone levels were associated with higher SERT binding in the prefrontal cortex. Moreover, allopregnanolone levels were negatively associated with measures of alertness, although this finding was not mediated by prefrontal cortex SERT binding. These findings suggest a link between the typical psychological well-being experienced in the follicular phase when allopregnanolone levels are low and higher SERT in the prefrontal cortex, a region for higher cognitive functions and top-down regulation of emotions.

    Skrivande och blivande: konstruktioner av skönlitterärt skrivande i handböcker och läromedel 1979-20152019Doctoral thesis, monograph (Other academic)
    Abstract [en]

    The focus of this study is descriptions of literary writing in pedagogical texts. The aim is to analyse how writing and writing subjects are constructed in pedagogical texts on writing published in Sweden between 1979 and 2015. The analysed texts comprise three different kinds: handbooks for creative writing, textbooks for upper secondary school and textbooks for teachers of writing. In the thesis the constructions of writing and writing subjects are connected to different discourses of writing as well as ideological tendencies in society. 

    The study starts by reviewing relevant research about writing in school, in leisure time or in the field of creative writing. Roz Ivanič’s framework for analysing discourses of writing is presented and expanded with two further discourses: the discourse of support and the market discourse. Furthermore, theoretical perspectives from Michel Foucault, Zygmunt Bauman and Richard Sennett are presented. 

    In the analysis constant and changing norms of writing are discussed in relation to the presented framework and theoretical perspectives. The analysis reveals the close connection between the writer and the written text, in the handbooks and in Strömquist’s Skrivprocessen. To succeed as a writer one needs to start from one’s own experiences, since it is crucial to put something personal, a part of oneself, into the writing. At the same time writing is said to create the writing subject, which means that one should both find – or create – and express the self through writing. After this, writing as either work or play, and the purpose of writing, are analysed. Chapter three discusses the handbooks and is chronologically structured. While writing during the 1980s was constructed as a political act, in recent years it is instead constructed as an activity aimed at finding happiness or making money. Chapter four analyses the textbook Svenska timmar and shows how literary writing was a key part of textbook writing in 1989, but is almost non-existent in the textbook from 2011. The construction of the writing subject goes from the playful and creative writer, to a writer concerned with being correct and writing accurately. In chapter five the results are linked to tendencies in society. The changes in the constructions of literary writing can be seen as part of a neo-liberal, individualized ideology, as well as an exception from, or counterpart, to the same. The final chapter concludes by discussing the constructions of writing and writing subjects, focusing on the connection between writing and reading – and the handbook as a genre.

    On the operation of light-emitting electrochemical cells2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    We are in the midst of a technological revolution that permeates nearly all human activities; artificial light is one of the most visible contributors in this societal change. If more efficient, green, and versatile light sources can be developed, they might improve the life of millions of people around the world while causing minimal damage to our climate and environment. The unique operational mechanism of the light-emitting electrochemical cell (LEC) makes it an ideal fit for some unconventional and emerging uses of light, in for example medicine and security.

    By exploiting this operational mechanism, in which mobile ions enable electrochemical doping of a luminescent polymer, we have designed and fabricated new bilayer LEC architectures. The bilayer LEC features patterned light emission that is easily adjustable during fabrication, and that can be configured to suit new applications of light. Given the light-emitting nature of the LEC, it is somewhat surprising that the optical understanding of its operation is rather limited. To fill this knowledge gap, we investigate how the optical properties of the luminescent polymer respond to electrochemical doping. We find that the complex-refractive index spectrum in the active layer of an LEC, as a direct result of the doping, varies in both space and time. The thin-film structure of an LEC implies that computational predictions of its luminous output need to consider internal reflections and interference. Finally, we implement a doping dependent optical thin-film simulation model. It enables us to precisely replicate the experimental luminance and angle-dependent emission spectrum for a range of LECs with different thicknesses. Using the model we can also identify and quantify many of the different optical loss mechanisms in LECs, which has not previously been done. The insights that we have collected on the path towards our present model will be useful for computational determination of device parameters that are otherwise difficult to acquire.

    The improved understanding of the optical operation of LECs is important for the maturation of the technology, as it facilitates formulation of relevant and accurate research questions. Hopefully, our results will accelerate the development of the field, so that useful products based on this technology can become available in the not too distant future.

    Ingen äger skogen: Människa och natur i Astrid Lindgrens Bröderna Lejonhjärta och Ronja Rövardotter2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This essay aim to explore how human and nature is presented in Bröderna Lejonhjärta and Ronja Rövardotter, by Astrid Lindgren. It also tries to answer the question how the relationship between the two is shaped; can any hierarchic structures be exposed in the relationship, and how do these, in that case, appear? The essay also problematize words and concepts along the way, such as nature, anthropocentrism and ecocentrism. The method for this study is an ecocritical theoretical base, with thematic analyzes of the books, regarding plot, relationships between characters and their surroundings, and also linguistic narratological techniques, such as the use of metaphorical elements. The different thematic episodes are put in relation to theories about vital materialism, presented in Vibrant Matter – A Political Ecology of Things, by Jane Bennett. I also do a comparative analysis between the two books by Lindgren, with the purpose of highlighting important differences and similarities. The essay ends by discussing how the main characters can be seen as very caring in their relationship to their surroundings, and how one, by applying the theories presented by Bennett, can interpret this caring as a strive towards existing in harmony with, and equal to, nature; a sort of mode or view that Bennett describes as a horizontal position. During the discussion I describe how this strive and position is expressed, and how these are interacting with cyclical systems such as the changes of the seasons and shift between life and death. The books as literature for children, and the main characters as children, is discussed in relation to this, supported by the text “När du är bättre än vi – Jantelagen, skammen och barnlitteraturen” by Maria Jönsson, from the book Du ska inte tro att du är något – Om Jantelagens aktualitet.

    Weight loss improves disease activity in patients with psoriatic arthritis and obesity: an interventional study2019In: Arthritis Research & Therapy, ISSN 1478-6354, E-ISSN 1478-6362, Vol. 21, article id 17Article in journal (Refereed)
    Abstract [en]

    Background: Obesity is over-represented in patients with psoriatic arthritis (PsA) and associated with higher disease activity, poorer effect of treatment and increased cardiovascular morbidity. Studies on the effects of weight loss are however needed. This study aimed to prospectively study the effects of weight loss treatment with very low energy diet (VLED) on disease activity in patients with PsA (CASPAR criteria) and obesity (body mass index BMI ≥ 33 kg/m2).

    Methods: VLED (640 kcal/day) was taken during 12–16 weeks, depending on pre-treatment BMI. Afterwards, an energy-restricted diet was gradually reintroduced. Weight loss treatment was given within a structured framework for support and medical follow-up.

    Treatment with conventional synthetic and/or biologic disease-modifying anti-rheumatic drugs was held constant from 3 months before, until 6 months after baseline.

    Patients were assessed with BMI, 66/68 joints count, Leeds enthesitis index, psoriasis body surface area (BSA), questionnaires and CRP at baseline, 3 and 6 months. Primary outcome was the percentage of patients reaching minimal disease activity (MDA) and secondary outcomes were reaching Psoriatic Arthritis Response Criteria (PsARC) and American College of Rheumatology (ACR) response criteria.

    Results: Totally 41/46 patients completed the study, 63% women, median age 54 years (IQR 48–62). At baseline increased BMI was associated with higher disease activity and poorer function.

    The median weight loss was 18.7 kg (IQR 14.6–26.5) or 18.6% (IQR 14.7–26.3) of the baseline weight. A majority of the disease activity parameters improved significantly after weight loss, including 68/66 tender/swollen joints count, CRP, BSA, Leeds enthesitis index, HAQ and patient VAS for global health, pain and fatigue. A larger weight loss resulted in more improvement in a dose-response manner. The percentage of patients with MDA increased from 29 to 54%, (p = 0.002). PsARC was reached by 46.3%. The ACR 20, 50 and 70 responses were 51.2%, 34.1% and 7.3% respectively.

    Conclusions: Short-term weight loss treatment with VLED was associated with significant positive effects on disease activity in joints, entheses and skin in patients with PsA and obesity. The study supports the hypothesis of obesity as a promotor of disease activity in PsA.

    ”Jag tror det behovet kommer explodera”: En studie om bibliotekarier- och journalisters kompetensbehov i yrkespraktiken i förhållande till utbildningsinnehållet.2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Uppsatsens syfte är att undersöka hur nyexaminerade bibliotekarier och journalister upplever sin kompetens i yrkespraktiken i förhållande till utbildningsinnehållet.

    Utifrån analys och kodning har teman som pedagogik och teknik urskilts som kompetensbehov bland bibliotekarier och journalister i deras yrkespraktik. Bland annat upplever bibliotekarier och journalister att de vill ha mer praktiska inslag i utbildningsinnehållet och tona ner det akademiska. Före detta studenter inom biblioteks- och informationsvetenskap vill ha mer pedagogisk kunskap och lära sig mer om bemötande samt att mer fokus på litteraturkunskap hade varit nyttigt i yrkeslivet. Före detta studenter inom journalistik önskar mer kunskap inom webbjournalistik som sociala medier, men också en större grund inom rättsjournalistik, samt bättre förståelse om branschen och vilka förutsättningar och arbetsformer som existerar.

    Care providers' perceptions towards challenges and opportunities for service improvement at diabetes management clinics in public primary health care in Muscat, Oman: a qualitative study2019In: BMC Health Services Research, ISSN 1472-6963, E-ISSN 1472-6963, Vol. 19, article id 18Article in journal (Refereed)
    Abstract [en]

    BackgroundThe literature has described several challenges related to the quality of diabetes management clinics in public primary health care centres in Oman. These clinics continue to face challenges due to the continuous growth of individuals diagnosed with type 2 diabetes. We sought to explore the challenges faced in these clinics and discuss opportunities for improvement in Oman.MethodsThis qualitative study was designed to include non-participant observations of diabetic patients and care providers during service provision at diabetes management clinics, as well as semi-structured interviews with care providers, at five purposively selected public primary health care centres. Care providers included physicians, nurses, dieticians, health educators, pharmacists, an assistant pharmacist, a psychologist, and a medical orderly. The data were analysed using qualitative content analysis.ResultsThe study disclosed three different models of service delivery at diabetes management clinics, which, to varying degrees, face challenges related to health centre infrastructure, technical and pharmaceutical support, and care providers' interests, knowledge, and skills. Challenges related to the community were also found in terms of cultural beliefs, traditions, health awareness, and public transportation.ConclusionThe challenges encountered in diabetes management clinics fall within two contexts: health care centres and community. Although many challenges exist, opportunities for improvement are available. However, improvements in the quality of diabetic clinics in primary health care centres might take time and require extensive involvement, shared responsibilities, and implications from the government, health care centres, and community.

    Prevalence of comorbidities in cases of Middle East respiratory syndrome coronavirus: a retrospective study2019In: Epidemiology and Infection, ISSN 0950-2688, E-ISSN 1469-4409, Vol. 147, article id UNSP e35Article in journal (Refereed)
    Abstract [en]

    The Middle East respiratory syndrome coronavirus (MERS-CoV) is a life-threatening respiratory disease with a high case fatality rate; however, its risk factors remain unclear. We aimed to explore the influence of demographic factors, clinical manifestations and underlying comorbidities on mortality in MERS-CoV patients. Retrospective chart reviews were performed to identify all laboratory-confirmed cases of MERS-COV infection in Saudi Arabia that were reported to the Ministry of Health of Saudi Arabia between 23 April 2014 and 7 June 2016. Statistical analyses were conducted to assess the effect of sex, age, clinical presentation and comorbidities on mortality from MERS-CoV. A total of 281 confirmed MERS-CoV cases were identified: 167 (59.4%) patients were male and 55 (20%) died. Mortality predominantly occurred among Saudi nationals and older patients and was significantly associated with respiratory failure and shortness of breath. Of the 281 confirmed cases, 160 (56.9%) involved comorbidities, wherein diabetes mellitus, hypertension, ischemic heart disease, congestive heart failure, end-stage renal disease and chronic kidney disease were significantly associated with mortality from MERS-CoV and two or three comorbidities significantly affected the fatality rates from MERS-CoV. The findings of this study show that old age and the existence of underlying comorbidities significantly increase mortality from MERS-CoV.

    Same-sex parental leave: Legislation and equality2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Sweden is known to have one of the world's most generous parental insurances, both in length and flexibility which has led to a high maternity rate and more women in paid work. The political work on equality in Sweden has the goal that women and men shall have the same power to shape society and their own lives. This has led to legislation aimed at getting fathers to stay more at home with their children. There has been plenty of research on this subject so this study goes off the main track and looks at how legislation around parenthood works for same-sex couples and if paternal leave is shared more equally between same-sex parents than heterosexual parents. Discourse analysis of the legislation and a survey with same-sex families followed by interviews indicate that samesex couples share parental leave more equally than heterosexual couples. Legislation works well for most same-sex families except for the process of related adoption. Reasons for more equal sharing of parental leave is hard to find but could depend on the fact that same-sex couples have been couples for a longer time, than heterosexual couples, before deciding to have children. Wage gap between men and women is a reason why heterosexual couples do not share equally and it could be vice versa for same-sex couples.

    Snapshots from Between: Non-binary identity construction on Instagram2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Though technically not a new phenomenon historically or geographically, non-binary identities arestarting to be more visible in Sweden, and have become a topic of both discussion concerninghuman rights and anti-discriminatory practices, but also mockery. In this thesis I wanted to have acloser look at how Swedish people identifying as neither wholly male nor female presentthemselves on social media in text and image, as well as how they describe the resistance they meetin regards to their identity and choices of presentation. Its theoretical basis lies in works of JudithButler, Jack Halberstam and Lee Edelman to examine which societal structures the subjects of thisstudy have to relate to. The source of my empirical material are ten Instagram accounts, which wereanalysed via an integrated discourse psychology/discourse theory approach. During the period ofmaterial collection, an incident in the shape of a public debate concerning trans questions had aconsiderable impact on the lives of the subjects of this study, consequentially making it a significanttheme of the thesis. The results show the difficulty of trying to hold a balance between or outsidethe gender and/or sex binary in a society which only recognizes male and female, as well as theconflicts of identity which can arise when one’s gender identity clashes with other importantpersonal values.

    Ett land att förälska sig i: Diskurser om kön, nation och sexualitet i Försvarsmaktens reklamer2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In 2018, the compulsory military service will be reinstated in Sweden and will, for the first time, be comprised of both men and women. The Swedish Armed Forces are looking to raise their diversity and wants to reflect the population of the Swedish society and are therefore working actively with their marketing to reach groups that have previously been excluded. The purpose of this thesis is to examine what type of image of Sweden the Swedish Armed Forces are (re)producing through their marketing and how it is used to try and interpellate new, poten-tial recruits. This will be done by examining four advertisement campaigns as well as comments retrieved from the Swedish Armed Forces social media accounts. The analysis will be conducted through a semiotic image analysis and a discourse analysis inspired by Laclau and Mouffe. The essay takes its theoretic starting point in a feminist critique against militarism and highlights the issues of using women and/or LGBTQ-people in the armed forces as symbolic figures of modernity and democracy. The study’s result shows that inclusion becomes a way for the armed forces to improve their own image and elude scrutiny regarding their own problematic structures by positioning themselves as an agency of good. This means that, by the inclusion of marginalized groups, there is as risk of legitimizing the Swedish Armed Forces existence, while still maintaining the problems that these groups are subjected to.

    Det befriande ansvarets paradox: En genusvetenskaplig studie av detfeministiska jämlikhetsinitiativet #killmiddag2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Currently, men’s responsibility is the focus of much of the public talk on gender equality in Sweden.This has given rise to a number of organisations carrying the overall ambition to include menin what has traditionally been regarded as a women´s issue. One of these initiatives is called #killmiddag,”dinner for guys”, and can be understood as a call out for men to get together and have intimateconversations with each other in order to free themselves from destructive masculinitynorms. In this thesis, the feminist equality initiative #killmiddag is scrutinized with the aim to findwhat possibilities and restraints the initiative might give rise to in regards to issues connected togender equality. The empirical material consists of the initiatives conversational guides and instructionsalong with a number of press articles published between the years of 2016-2018. In order toanalyze this material, specifically the role of conversations, experience and emotions this thesis usesresearch about therapeutic discourse and how this is linked to contemporary ideals about intimacy.This analysis focuses on how problems and solutions are articulated discursively, and how categorieslike ”gender equality” is filled with meaning. Using research concerning the effects of marketbasedforms of governing, my goal is to further contribute to a discussion about what happens with”gender equality” when market rationalities come to replace conflicting interests in politics. Assistedby a poststructuralist approach this thesis highlights some of the problems in using personalexperience as a source of objective knowledge, and how the use of emotions and intimacy, withtheir inbuilt epistemological fragility, might not necessarily be considered apt when striving for politicalchange.

    Translation Stress Regulates Ribosome Synthesis and Cell Proliferation2018In: International Journal of Molecular Sciences, ISSN 1422-0067, E-ISSN 1422-0067, Vol. 19, no 12, article id 3757Article, review/survey (Refereed)
    Abstract [en]

    Ribosome and protein synthesis are major metabolic events that control cellular growth and proliferation. Impairment in ribosome biogenesis pathways and mRNA translation is associated with pathologies such as cancer and developmental disorders. Processes that control global protein synthesis are tightly regulated at different levels by numerous factors and linked with multiple cellular signaling pathways. Several of these merge on the growth promoting factor c-Myc, which induces ribosome biogenesis by stimulating Pol I, Pol II, and Pol III transcription. However, how cells sense and respond to mRNA translation stress is not well understood. It was more recently shown that mRNA translation stress activates c-Myc, through a specific induction of E2F1 synthesis via a PI3K delta-dependent pathway. This review focuses on how this novel feedback pathway stimulates cellular growth and proliferation pathways to synchronize protein synthesis with ribosome biogenesis. It also describes for the first time the oncogenic activity of the mRNA, and not the encoded protein.

    Begreppens betydelse för förståelsen: Lärares arbete med ämnesspecifika begrepp i SO-ämnena i årskurs 42019Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The aim of this study was to examine how teachers work with subject-specific concepts in fourth grade social science classes, what challenges they meet, what methods they use and what additional adjustments they make for students with language difficulties. We conducted semi-structured interviews with four primary school teachers and observed twelve lessons in total. Results show that the teachers in general pay attention to subject-specific concepts in the lesson planning. However, also discrepancies were shown between teachers’ acknowledgement of the importance of subject-specific concepts and the actual work with it. Overall, teachers made use of a variety of methods, such as reading aloud, pair and group work, visualisations and pictures as well as feedback and repetition. Main challenges were the substantial differences in pupils’ background knowledge and reading skills as well as an increased subject knowledge and skill expectations in grade 4 – all in relation to experienced time pressure. Additional adjustments for pupils with language difficulties took place on a general level, i.e. were rather carried out as routinised teaching methods for all pupils than adjustments for individual ones. These were e.g. clear visualisations of lesson plans and goals, using a smart board, group and pair work and modelling. The results suggest that teachers are aware of the importance of subject-specific concepts, and that these can be an obstacle to learning, particularly for pupils with language difficulties. However, more knowledge and professional support in form of specialist teacher consultation are needed to be able to cope with the multiple subject- and language-related challenges in the classroom, and in order to offer best support for every pupil.

    Francisella tularensis: persistence, dissemination and source attribution: a theoretical and computational approach2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The bacterium Francisella tularensis causing tularemia in humans and other mammals displays little genetic diversity among genomes across temporal and spatial scales. F. tularensis infects humans with an extremely low infectious dose and causes natural seasonal tularemia outbreaks. During the Cold War, this bacterium was developed as a biological weapon.

    In paper I, we aimed at investigating the genetic diversity of F. tularensis over space and time and were especially interested in the influence of spatial dispersal on the genetic diversity. By analyses of single-nucleotide polymorphisms (SNPs) among 205 F. tularensis genomes, we found that tularemia had moved from East to West over the European continent by dispersal patterns characterized by multiple long-range dispersal events. Evolutionary rate estimates based on the year of bacterial isolation from 1947 to 2012 indicated non-measurable rates. In outbreak areas with multiple recent outbreaks, however, there was a measurable rate of 0.4 SNPs/genome/year indicating that in areas with more intense disease activity, there is a detectable evolutionary rate. The findings suggest that long-range geographical dispersal events and mostly very low evolutionary rates are important factors contributing to a very low genetic diversity of F. tularensis populations.

    In paper II, we focused on a geographically restricted area with a history of frequent tularemia outbreaks to study F. tularensis persistence. By analyzing F. tularensis genomes from 138 individuals infected from 1994 to 2010 in Örebro County in Sweden and performing a long-term laboratory storage experiment, we explored the microbial population concept of a pathogen seed-bank. We found that eight indistinguishable genomes – each of them defined by no SNPs across 1.65 million whole-genome nucleotides – locally persisted over 2-9 years. We found unmeasurable SNP accumulation rates and overlapping bacterial generations among the outbreak genomes and that F. tularensis survived in saline for four years without nutrients. By these findings, and analyses of nucleotide substitution patterns, we suggest that a pathogen seed-bank effect is an important feature of F. tularensis ecology influencing genetic diversity.

    In paper III, we developed a new concept for source attribution of a F. tularensis sample. We aimed to identify genetic variation that is characteristic to laboratory culturing and we used culture amplification to identify genetic variation present at exceedingly low frequencies in a sample. Based on a biological enrichment scheme followed by high-throughput sequencing, we could track genetic variation back to a source sample. These results suggest that the concept has potential for linking a F. tularensis sample to its laboratory source sample.

    Taken together, the results presented in this thesis provide new understanding of the dissemination patterns and local persistence of tularemia. This is important for the interpretation of molecular epidemiology investigations of the disease. In a wider context, the results demonstrate how spatial dispersal and a microbial seed-bank effect may contribute to the diversity of a disease-causing agent. Finally, we have described a promising concept for source attribution of F. tularensis samples

    Art Education: mostly for girls?2013In: Education Inquiry, ISSN 2000-4508, E-ISSN 2000-4508, Vol. 4, no 3, p. 577-593Article in journal (Refereed)
    Abstract [en]

    This article discusses whether and how Art education is gendered, and whether and how the art world is gendered. The history of Art education is briefly described from a gender perspective, as well as some current reports on Art education in Sweden. The article draws on material from a postgraduate study about Art education and gender. Art lessons were observed and pupils were interviewed about their views on art. Based on the interview data, it is suggested that one reason that Art education is femininely gendered is that the subject is strongly associated with expressing feelings. Concerning the gendering of the art world, more women than men are professional artists today. However, due to the fact that there is a male art historical canon, that is taught in schools, the art world appears to be masculine, making ‘artist’ one possible position for boys within art education. That the art world seems masculine while Art education is gendered feminine is an interesting paradox worthy of further investigation.

    Abstract [en]

    The purpose of the study is to investigate how teachers and special education teachers, through collegialcooperation, can help all students and especially those in special needs. This is done by creating aneducational model that will eliminate obstacles in terms of school difficulties and help students tointerpret instructions in examinations, for example those of the national tests in Swedish at uppersecondary school. An educational model was constructed after interviews with teachers followed bygroup discussions. The implementation of the model was then observed in the classrooms, discussed withthe students and evaluated by pre- and post-testing. The effect of the model was found to be small thusthe reasons for this outcome are discussed in the final section of the paper.

    Skolverkets bedömningsstöd: Ett effektivt verktyg för att identifiera elever i behov av stöd?2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In Sweden, a compulsory national assessment of all students’ reading skills has been implemented by the National Agency at the end of 1st grade to improve early identification of students in need of extra support in their reading development. The purpose of the present study was to evaluate to what extent the compulsory criterion-referenced assessment identifies children with poor reading skills in comparison to two commonly used standardized and norm-referenced assessment materials measuring word reading skills and reading comprehension. Fifty-three Swedish students participated in the compulsory national assessment at the end of 1st grade and were administered the norm-referenced assessments of reading comprehension and word reading at the beginning of grade 2. Furthermore, a survey was distributed to 27 teachers in primary school to explore teachers’ experiences of using the compulsory national assessment in grade 1. Results indicated that the national compulsory assessment in grade 1 only identified 8 % of the students identified with reading comprehension difficulties and weak word reading skills in the norm-referenced standardized assessment in grade 2. A majority (70 %) of the teachers question the criterion based national assessments’ capacity to identify children at risk in their reading development. Implications for early identification of reading difficulties in Swedish primary school are discussed.

    Stolthet och skvaller: En komparativ analys mellan Jane Austens Stolthet och fördom och Curtis Sittenfelds Sanning och skvaller2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This essay analyses Curtis Sittenfeld’s novel Sanning och Skvaller as an adaption of Jane Austen’s Stolthet och fördom. The purpose of this essay is to take a closer look at how the characters and the plot changes in Sittenfeld’s version compared to the original. The character analysis mainly focuses on Mr. Wickham, lady Catherine de Bourgh and Caroline Bingley as characters, as well as Mary Bennet and how her sexuality is portrayed. Elizabeth Bennet’s relationship with Mr. Darcy and the importance of a proposal and a marriage is also something that this essay analyses. The reception of the novel is something that will be addressed by highlighting some of the negative, and positive, reviews that the novel received upon publication. The discussion at the end brings up whether or not Sittenfelds novel can be classified as an adaption after changing so much of the story, how the elements in the new version changes its believability and how the problematic aspects may ruin the story.

    Effect of Feature Extraction when Classifying Emotions in Speech - An Applied Study2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The demand for machines that can interact with its users through speech is growing. For example, four of the world’s largest IT companies; Amazon, Apple, Google and Microsoft, are developing intelligent personal assistants who are able to communicate through speech. In this thesis, we have investigated the effect of feature extraction when classifying emotions in speech, using a convolutional neural network (CNN). We used the software openSMILE to extract two sets of features, and one set of raw data, from recorded audio, and compared the CNN’s classification accuracy of the sets with eight, five and three classes of emotions. We used one architecture of the CNN, to be fair when comparing each feature set, and implemented it using Keras. The CNN architecture was developed by an experimenta lapproach.The feature set that gave the highest accuracy managed to reach 39 % accuracy when classifying eight emotions (random guessing would yield around 12.5 % accuracy on average), 53 % with five emotions (compared to around 20 % if just guessing), and 69 % with threee motions (compared to around 33 % if just guessing). This set also performed best whendistinguishing emotions from each other.The result shows that using feature extraction improves the accuracy, but more features does not necessarily increase accuracy.While the classification accuracies in this study may seem low, it is important to remember that even for humans, it can be hard to distinguish different feelings based on just the pitch of other people’s voices.

    When words are not enoughAn evaluation of character n-grams and function words in author identification of musical artists2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    When we write texts we unconsciously leave prints behind, these prints are things such as the words used, punctuation, special characters and more. There are several different approaches to author identification that utilises these features. All these methods have been applied to avariety of texts, everything from papers to poems, e-mail and forum posts. This study will use lyrics where the artists are the authors, on these the performance of two common features will be compared.The two features that will get evaluated are character n-grams and function words. These are some of the most prominent features within author identification, where both have a track record of good performance. With high hopes for the performance the results showed that neither feature could reach the expected results. They were expected to achieve 70% and 65% accuracy respectively, however, the achieved average accuracy was only 40% and 35%. Even with the poor results some interesting finds were made. Some artists would have multiple band members write the songs which caused concern that it would affect the performance. Interestingly the results showed that multiple authors did not bad effect to the performance, in some cases they performed better than single authors.

    Abstract [en]

    This is an ecocritical analysis of the novel Glupahungern by Andrea Lundgren. I investigate how nature is viewed by looking at two things. First, I look at two functions in the novel. I analyze the function of characters that seem to be in between the human side and the animal side. I call them creatures of the border. I also analyze the function of places that can be seen as borderlands. Places between nature and society. Second, I do a small comparison between Glupahungern and the novel Hjortronlandet by Sara Lidman since they both are written by authors from the north of Sweden and the novels also takes place in the northern parts. Through this comparison I find similarities between the novel and how nature is viewed in them and I come to the conclusion that the place has an impact on the view of nature.

    Keywords: Nature, Border, Ecocriticism, View on nature, Northern Sweden

    Hållbar undervisning?: En kvalitativ studie om lärares förutsättningar för att implementera undervisning för hållbar utveckling i samhällskunskapsämnet2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Den här studiens syfte är att undersöka lärares förutsättningar för att implementera undervisning för hållbar utveckling i ämnet samhällskunskap. Undersökningen har sin bakgrund i internat-ionella och nationella dokument där undervisning för hållbar utveckling framhålls som ett verk-tyg för att uppnå en hållbar utveckling och något som ska genomsyra all undervisning. I studien intervjuades två samhällskunskapslärare om hur de upplever sina förutsättningar för att imple-mentera och arbeta med undervisning för hållbar utveckling. I studien analyserades också två digitala läromedel för att ta reda på hur hållbar utveckling framställs i läromedlen och vidare hur detta påverkar lärarnas förutsättningar för undervisning för hållbar utveckling. Materialet analyserades utifrån implementeringsteori med fokus på läraren som frontbyråkrat och de ide-altypiska frågorna förstå, vilja och kunna.

    Resultatet visade att lärarna generellt upplever sina förutsättningar som goda men att det finns faktorer som påverkar och försvårar lärarnas förutsättningar för att implementera undervisning för hållbar utveckling. Framförallt försvåras implementeringen av att lärare inte tillgodoses med mer resurser. Brist på tid gällande både planering, undervisning samt tid för fördjupning och arbete med andra kollegor men även förståelsen för begreppet hållbar utveckling påverkar lä-rares förutsättningar för att implementera undervisning för hållbar utveckling. I slutsatsen slås det fast att skolan på området undervisning för hållbar utveckling blir ojämlik när läraren har stor betydelse för om elever får undervisning för hållbar utveckling eller inte.

    Moving Climate Change Adaptation in the Forest Sector Forward Through Stakeholder Empowerment: A Case Study on Västerbotten County, Sweden2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Climate change and what to do about it, both in relation to mitigation and adaptation, is a strongly debated topic. One of the areas that has been brought forward as pivotal in both adaptation and mitigation is the forest sector. Yet, the scientific literature reveals that adaptation measures are to date seldomly implemented in this sector. Much is known about hurdles in the way of adaptation measures, but far less is known on how to empower local stakeholders to move adaptation forward. Therefore, this thesis examines if a new approach to climate change adaptation in the forest sector can help to empower local stakeholders to take adaptation actions. A theoretical framework for change that focusses on strengths in the surroundings of the stakeholders is developed with insights of the Institutional Analysis and Development framework, Empowerment Theory, Asset Based Community Development, and Appreciative Inquiry. Based on this framework, a method is developed and applied in a participatory backcasting workshop with students with a focus on Västerbotten County, Sweden. The results from this case study show that the new approach contributed to the empowerment of the participants and to a more holistic understanding of local climate change adaptation in the forest sector.

    Abstract [en]

    The purpose of this examination is to examine from a feminist perspective how men and women have been represented in five civic textbooks for Swedish Upper Secondary School. The examination has a time perspective from the 1970´s until today, during this time Swedish Upper Secondary School´s value has all along been equality between men and women. To reach the results both quantitative and a qualitative method has been used. The results give indications that men´s and women’s representation have been changed over time, in the early textbooks women was described as just women and were linked to their bodies while men were presented as people with names and careers. In the latest textbook sex and gender where no longer discussed but men where over- represented in both text and pictures. This give indications that civic textbooks have change the way they wright about men and women. In the early textbooks the authors wrote about men and women which gave a clearly picture of the differences that was presented, and which readers can question. In the latest textbook the authors no longer wrote about sexes but choose more quietly to over- represent men in both text and pictures. These civic textbooks showed a transformation over time in the representation of men and women, the early ones showed a representation that we could see clearly and question, while the newest showed a representation which more silent choose to give men more space. All the textbooks that has been examined, in different ways didn´t reach the School value of equality between men and women.

    Abstract [en]

    This case study is an analysis of Swedish foreign policy and security policy from two feminist perspectives. The Swedish government has declared that they are feminist and that they will apply a feminist foreign policy. This even though there are several definitions of feminism and the fact that the understanding of security isn’t necessarily the same within the feminist foreign policy and the security policy. The investigation has the purpose of understanding Swedish foreign and security policies as well as seeing how compatible they are. To do this, the analysis concentrates on the ideas within the theories and the policies. The theories are two feminist perspectives, liberal feminism and feminist critical theory, which give us an understanding of how to interpret our policies. The study finds that you can see traces of both liberal feminism and feminist critical theory in our policies, but mostly liberal in our security policy. Furthermore, liberal feminism shows that the policies works quite well together and has almost no criticism to it. Feminist critical theory on the other and shows that the policies aren’t as compatible and finds several flaws.
