    Effekter av psykofarmaka på planktonsamhällen - Experimentell pilotstudie.2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    As a consequence of society's consumption of psychotropic drugs, sources of these substances is detected in municipal wastewater plants as unchanged, including their metabolites. Reaching the aquatic environment, effluents contributes with a significant source of these substances which has been shown to affect the structure and function of aquatic organisms. It is important to create experimental evidence on how primary-producing aquatic ecosystems respond to the exposure of commonly prescribed psychotropic drugs. The aim of this study was to investigate possible effects of selected psychotropics; fluoxetine and oxazepam, to plankton communities from a freshwater recipient. Over an 7-day period identified organisms; Mesocyclops leuckarti, Chlorella vulgaris, Monoraphidium mirabile, Monoraphidium contortum, Monoraphidium griffithii och Glaucoma scintillans, were exposed to fluoxetine; 500 and 50 μg/l and oxazepam; 1700 and 170 μg/l. C. vulgaris and G. scintillans, turned out to be most sensitive to high levels of fluoxetine than other identified species. C. vulgaris and G. scintillans decreased by 70 and 100 % respectively, as a result of 500 ug/l fluoxetin. However, exposure levels in the experiment are much higher than measured values ​​in outgoing wastewater, and is therefore not considered to be acute toxic to non-target species comparable to those in this study.

    Goda relationer, motivation och genusmedvetenhet: En studie om flickor med ADHD och skolcoacher2017Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Specialpedagogiska frågeställningar handlar bland annat om normalitet och avvikelse, integrering, delaktighet, lärande, makt och inkludering enligt Jakobsson & Nilsson (2011). Det är utifrån de specialpedagogiska frågeställningarna som vi har valt att undersöka hur flickor som fått diagnosen ADHD under senare delen av sin skoltid, eller till och med efter att de slutat skolan, har upplevt sin skolgång. Alla de intervjuade flickorna beskriver att de under sin skoltid har mött någon som uppmärksammade dem och deras behov, och som därför kom att bli betydelsefull för att de skulle klara av skoltiden. Utifrån flickornas berättelser och i förhållande till att vi under vår studietid på Linnéuniversitetet har blivit uppmärksammade på det relationella perspektivet som kortfattat kan beskrivas som ett intresse för vad som sker människor emellan, valde vi att även intervjua skolcoacher. Skolcoacherna som vi mötte har i uppdrag att fånga upp och arbeta förebyggande och främjande för att stötta alla elever så att skolan ska vara en “skola för alla”.

     

    Metoden vi använde var dels intervjuer och dels fokusgrupper. Till analysen användes teorier som behandlar betydelsen av att ta hänsyn till relationer, motivation och genus i arbetet med flickor med ADHD.

     

    Resultatet visade att de flickor med ADHD, som vi har intervjuat, hade känt att deras skolsvårigheter berodde på dem själva. Dessutom hade deras skolsvårigheter ofta har lett till skolk och skolfrånvaro. Vi ser också i vårt arbete att de intervjuade skolcoacherna och flickorna upplever att flickor och pojkar med ADHD och/eller problem med skolk bemöts olika i skolan.

    KPI´s- Measuring and evaluating in order to increase efficiency2008Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: AA Logistics Sweden is having logistic efficiency problems, and at this point they do not have performance measurement in terms of KPI´s. Due to constant development and demand on their products, there have not been enough resources available to perform these measurements.

    Purpose: Our purpose is, on the basis of service level and turnover speed, to measure efficiency in terms of KPI’s at AA. It is also to design record sheets that can assist AA to increase the efficiency over time.

    Methodology: Interviews with managers and employees, in order to have a solid foundation for what to look for and analyse in the ERP system. The empirical material that was received was analysed on the basis of different theories.

    Result, conclusions: We have developed values for each KPI and also suggested SMART goals that in the long run will contribute to increasing the logistic efficiency.

    "I feel like a person who is already dead": Förlust, läkning och magisk realism i tre japanska romaner2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In this thesis the subject of grief and healing are examined in three novels by the Japanese writers Hiromi Kawakami, Ruth Ozeki and Banana Yoshimoto. The method for the analysis is based on psychiatrist Elisabeth Kübler-Ross’ Five Stages of Grief theory, but in the analysis of these novels, it became clear that the grief/healing-stages for the protagonists are not expressed in the exact same manner as the non-fictional patients of Kübler-Ross’ study. The analysis shows that this is partly due to the fact that the narratives take place in Japan and that there is a clear intervention where the writers have used magical interruptions in their realistic portrayal of bereavement, to help the protagonists begin to recover. These magical interruptions, this thesis states, are the use of magical realism, especially connected to the long history of Japanese folklore and myth. As a result, this thesis presents a modified model of analysis, which also reflects how the protagonists filled with bereavement and sorrow can be helped to heal and recover by the interruption of fantastic and magical events. Through this study it has become clear that not only is the need for healing significant but the need for family, relationships and a sense of belonging are just as important. To re-connect with their lost loved ones, whomever they may be, these characters must cross through the magical interventions within the narratives and dare to reach out to the people around them, strengthened by their loss and trauma, rather than fearing relationships with others due to previous trauma and grief.

    Är STCW-kraven i STCW A-III/1 uppfyllda i kursplanerna?: En litteraturstudie om Sjöfartshögskolan i Kalmars kursplaner och STCW-koden2017Independent thesis Basic level (professional degree), 180 HE creditsStudent thesis
    Abstract [sv]

    Huvudfrågeställningen i studien var om Sjöfartshögskolan i Kalmar kursplaner uppfyller de krav som ställs i STCW del A-III/1 på utbildningsprogrammen för sjöingenjörer. Syftet med arbetet var att verifiera Sjöfartshögskolan i Kalmars kursplaners uppfyllelse av STCW-kraven enligt del A-III/1 för sjöingenjörer. Metoden som användes var en kvalitativ litteraturstudie där de i STCW uppställda kraven enligt del A-III/1 studerades och jämfördes med kursplanerna inom utbildningsprogrammet för sjöingenjörer på Sjöfartshögskolan i Kalmar.  Resultatet som framkom var att 72 % av kraven i A-III/1 var uppfyllda i kursplanerna för Sjöingenjörsprogrammet i Kalmar. Min rekommendation är att kursplanerna ses över och justeras för att bättre stämma överens med STCW-kraven, för att säkerhetsställa att kvaliteten på utbildningen är hög och konstant.

    Alla kan bidra med någonting: Effektivt ledarskap ur ett mångfaldsperspektiv2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose with this study is to explore what leadership styles and behaviours that are effective to use when managers lead employees with mental disabilities. Employees with mental disabilities can have different obsticles to overcome in a workplace, but the managers treatment is an important key for their success. 

    The subject has been examined in a quantitative study by interviewing four managers that has employees with mental disabilities about leadership, values, commitment and empowerment. All managers talk about values as an important part of leading these employees effectivly but the advantages of empowerment is unclear as some employees needs more guiding to manage their work. The managers need to have focus on people first, but has to focus on getting results too. In other words, the manager needs to focus on the employees abilities.

    Cosmic ray physics with the LOFAR radio telescope2019In: Journal of Physics: Conference Series, Institute of Physics Publishing , 2019, no 1Conference paper (Refereed)
    Abstract [en]

    The LOFAR radio telescope is able to measure the radio emission from cosmic ray induced air showers with hundreds of individual antennas. This allows for precision testing of the emission mechanisms for the radio signal as well as determination of the depth of shower maximum X max , the shower observable most sensitive to the mass of the primary cosmic ray, to better than 20 g cm -2 . With a densely instrumented circular area of roughly 320 m 2 , LOFAR is targeting for cosmic ray astrophysics in the energy range 10 16 -10 18 eV. In this contribution we give an overview of the status, recent results, and future plans of cosmic ray detection with the LOFAR radio telescope. © Published under licence by IOP Publishing Ltd.

    Status of the lunar detection mode for cosmic particles of LOFAR2019In: Journal of Physics: Conference Series, Institute of Physics Publishing , 2019, no 1Conference paper (Refereed)
    Abstract [en]

    Cosmic particles hitting Earth's moon produce radio emission via the Askaryan effect. If the resulting radio ns-pulse can be detected by radio telescopes, this technique potentially increases the available collective area for ZeV scale particles by several orders of magnitude compared to current experiments. The LOw Frequency ARray (LOFAR) is the largest radio telescope operating in the optimum frequency regime for this technique. In this contribution, we report on the status of the implementation of the lunar detection mode at LOFAR. © Published under licence by IOP Publishing Ltd.

    Overview and status of the lunar detection of cosmic particles with LOFAR2018In: Proceedings of Science: 35th International Cosmic Ray Conference, ICRC 2017; Bexco, Busan; South Korea; 10-20 July 2017, Sissa Medialab Srl , 2018Conference paper (Refereed)
    Abstract [en]

    When a cosmic particle hits matter it produces radio emission via the Askaryan effect. This allows to use Earth's moon as detector for cosmic particles by searching for these ns-pulses with radio telescopes. This technique potentially increases the available collective area by several orders of magnitude compared to current experiments. The LOw Frequency ARray (LOFAR) is the largest radio telescope operating in the optimum frequency regime for corresponding searches. In this contribution, we report on the design and status of the implementation of the lunar detection mode at LOFAR. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives 4.0 International License (CC BY-NC-ND 4.0).

    Hur lärare undervisar i problemlösning: En kvalitativ studie om lärarens roll vid problemlösning i lågstadiet1987Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med studien är att undersöka hur lågstadielärare arbetar med problemlösning utifrån frågeställningarna vilka strategier lyfter lärare fram i problemlösningsundervisningen och vilken roll tar läraren i undervisningssituationer av problemlösning. Fär att samla in epiri till studien har tre lärare deltagit och deras före, under och efter problemlösningsundervisningen undersöktes. Lärarnas planering av undervisningen gav information om tankar och utgångspunkter i problemlösningen som sedan utfördes och som då observerades med hjälp av två observationscheman utifrån det teoretiska ramverket, bestående av Pólyas fyra faser (1945) och Smith och Steins fem undervisningspraktiker (2014). Observationerna kompletterades med intervjuer av observerade lärare. Insamlad data bearbetades och sammanställdes till ett resultat. Analyserades gjordes av resultatet med det teoretiska ramverket som filter. Studiens resultat visar att introduktionen av ett problem är viktigt för elevers förståelse för det. Lärarens förberedelse och förutsättande av lösningsmetoder och strategier innan lektionen bidrar till att de lyckades bättre med att tydliggöra den matematiska idén i diskussionsdelen av problemlösningens. Samtidigt visar resultatet att lärare lägger olika mycket vikt på att uppmärksamma utvärderingar och reflektion i problemlösningen. Övergripande visar studien att lärarna tar en stor roll i att hjälpa och kontrollera elevernas process i lösandet av problem. Det framkommer även att lärarnas aktiva urval av elevlösningar skiljer sig mellan lärarna.

    Skogsskötsel för att främja sociala och estetiska värden i ett friluftsområde i Trollhättans Stad2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Over 80% of Sweden's population lives in urban areas, and half of the country's forest visits will thus be in urban woodlands. Social values ​​- how the individual experiences the forest, and the impact of the forest visits on individual health and well-being, are pointing to the importance of managing the urban woodlands.

    When there comes to the cultivation of the urban woodlands there are usually many opinions to consider.

    This study aims to investigate the various opinions on the use and forestry in an urban recreation area in ​​the City of Trollhättan. The study addresses both general and in four cases specific suggestions on management methods.

    Data was obtained from both quantitative and qualitative study through survey, interviews and discussions with the users of the recreation area.

    Trollhättan's goal with the recreation area is to make it accessible to local residents. The users are mainly influenced by the accessibility therefore clearings and thinnings are appreciated. Clear cuts should be avoided, but can be used as a method if logging residues are removed afterward.

    Variation is important for the specific areas, the focus is laid on hardwood species. Where hardwood is missing the focus should be to create old and sparse forest.

    Bråk- och decimaltal i grundskolan: En systematisk litteraturstudie om likheter och skillnader i undervisning av bråktal respektive decimaltal.2018Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna systematiska litteraturstudie har haft sin utgångspunkt i att undersöka likheter och skillnader i undervisning av bråktal respektive decimaltal. Studien fokuserar också på vad som kan underlätta elevers inlärning och förståelse i mellanstadiet för dessa begrepp. Denna studies resultat har sin grund i 19 vetenskapliga artiklar. Resultatet framkom med ett flertal samband i undervisning av bråktal och decimaltal, nämligen vardagsnära situationer, tallinjen och storleksordning. Framställandet av vardagsnära situationer, är den aspekt som utgör en skillnad i undervisning av bråktal och decimaltal. Inom bråktal framställs vardagsnära situationer som pizza eller godis, medan vardagsnära situationer och decimaltal kopplas ihop med mätningar av vikt och volym. Resultatet visar att elevers inlärning av bråktal och decimaltal kan underlättas med hjälp av konkreta och abstrakta nivåer i matematikundervisningen. Viktiga slutsatser av resultatet är att elever främst har ett behov av en koppling till sin personliga vardag för att på ett enklare sätt öka sin kunskap inom bråktal och decimaltal.

    Tallinjen – ett hjälpmedel till att förstå bråk- och decimaltal?: En empirisk studie om vilket sätt tallinjen kan underlätta förståelsen för bråktal respektive decimaltal.2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna empiriska studie har sin grund i en tidigare genomförd systematisk litteraturstudie. Den systematiska litteraturstudien visade att tallinjen kan vara ett hjälpmedel när elever ska lära sig hantera bråk- och decimaltal. Resultatet från litteraturstudien gav uppkomst till denna studie vars syfte är att undersöka hur tallinjen kan vara ett hjälpmedel till att förstå bråktal och decimaltal. Denna studie har utförts med hjälp av att observera en femteklass där två lektioner utifrån Heddens (1986) nivåer semikonkret och semiabstrakt genomfördes samt intervjuer med fyra elever från samma femteklass. Semikonkret och semiabstrakt underlättade planeringen av lektionerna genom att förtydliga hur laborativa aktiviteter kan involveras i undervisningen. Resultatet visade att elevernas förståelse kring bråktal och decimaltal underlättades med hjälp av tallinjen när den ritades upp på tavlan, det vill säga när tallinjen befann sig i ett semikonkret sammanhang. Viktiga slutsatser av denna studie är att det finns ett flertal kritiska aspekter vilka kan orsaka problematik att förstå bråktal och decimaltal i kombination med tallinjen. Dessa kritiska aspekter är betydelsefulla att synliggöra och urskilja för att möjliggöra lärandet för eleverna på bästa sätt.

    Abstract [en]

    The main purpose with this essay has been to compare four different schoolbooks, for 7th to - 9 th grade, from four different publishers. Due to the essay range, it only focuses on the description of the civil war in former Yugoslavia. The schoolbooks have been written according to the guidelines of the newest curriculum plan (Lgr 2011). The results of this dissertation show how there are significant differences between the schoolbooks. Key actors in the wars and their description differ between the books. Another difference is the commencement year of the conflict and the number over refugees accounted for. One important finding made, is the degree of neutrality distinguishes from book to book. One of them have chosen to exclude all the actors and countries while other books chooses to include them

    VARSLEN ÄR LAGDA. NU VÄNTAR ALLA PÅ BESKED: En intervjustudie på ett logistikföretag2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Eftersom vi befinner oss i en global finansiell kris, har det blivit mer och mer vanligt att företag varslar ett stort antal människor. Vi anser det intressant att skriva om ämnet eftersom det i högsta grad är aktuellt. Logistikföretaget vi undersökte gör en stor omorganisation där stora delar av verksamheten läggs ner och flyttas från staden och cirka 70 % av enhetens anställda är varslade. Syftet med den här studien är att ta reda på nedskärningens betydelse för ett fåtal anställda, efter att varsel är lagda samt ta reda på hur ledaren kan motivera sina anställda vid nedskärning. Uppsatsen som följer är en empirisk kvalitativ studie, utfört på ett logistikföretag i Götaland. Studien baseras på sju semistrukturerade intervjuer, med företagets högsta lokala chef, två mellanchefer samt fyra medarbetare. Intervjupersonernas utsagor relaterades till några olika teorier och tidigare forskning om motivation och kommunikation. Författarnas egna reflektioner och idéer presenteras i uppsatsens diskussion. Analysen av utsagorna visar att intervjupersonerna inte är oroliga för att förlora jobbet, men de berättar att en del anställda är ängsliga. Beskedet om varsel har även inneburit större gemenskap hos de anställda då de har börjat prata med varandra till skillnad från tidigare då de pratade om varandra. Det framgår av resultatet att alla utom den högsta lokala chefen anser att informationen är bristfällig, då de flesta inte vet vad som kommer att hända mer än att de riskerar att bli arbetslösa. Cheferna försöker motivera sina anställda genom att informera om att deras ackordslön inte bara märks nu utan även framöver vid eventuell a-kassa.

    "Oj vad spännade, oj vad svårt": Den digitala skrivtavlans implementering i skola och förskola.2011Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie är att undersöka hur pedagoger upplever implementeringen och villkoren att arbeta med den digital skrivtavlan. Det har även varit av intresse att se vilka förväntningar det finns på användningen av Smartboarden. Metoden som användes för att ta fram svaren var kvalitativa intervjuer som genomfördes på en skola och en förskola. Det är tidigare forskning som ligger till grund för denna studies frågeställningar. Enligt flera forskare har Smartboarden ett brett användningsområde. Dock kan detta stora användningsområde endast komma till bruk om man är införstådd i arbetssättet.

    Resultatet baserades på respondenternas svar tillsammans med tidigare forskning. Det visade sig att implementeringen skett genom ett top down taget beslut av skolledning och rektorer. Dock var de flesta pedagoger positiva till införandet av Smartboarden i skolan. I förskolan var det spridda tankar kring implementeringen eftersom att en del pedagoger ansåg att Smartboarden hörde hemma i skolan och andra visste inte ens vad det var för något.  En slutsats att dra efter denna studie är att pedagogerna som använder sig av Smartboard måste få utbildning kring användningen för att det ska ge ett bra resultat i undervisningen och satsningen av det nya läromedlet.

    'Sometimes it feels as if the world goes on without me': adolescents' experiences of living with chronic fatigue syndrome2014In: Journal of Clinical Nursing, ISSN 0962-1067, E-ISSN 1365-2702, Vol. 23, no 17-18, p. 2649-2657Article in journal (Refereed)
    Abstract [en]

    Aims and objectives. To explore the experience of being an adolescent with chronic fatigue syndrome. Background. Despite ample research, chronic fatigue syndrome is still poorly understood, and there are still controversies related to the illness. Adolescents with chronic fatigue syndrome are often unable to attend school and lose social relations with friends. The challenges they face will affect their quality of life. Design. A qualitative, phenomenological hermeneutical design. Method. Six boys and twelve girls, aged 12-18, were interviewed, emphasising their own experiences living with chronic fatigue syndrome. Analyses were performed using a phenomenological hermeneutical method. Results. The core theme, 'Sometimes it feels as if the world goes on without me', encompasses the feelings an adolescent living with chronic fatigue syndrome might have about life. The core theme was supported by four subthemes: 'On the side of life - locked in and shut out'; 'the body, the illness and me'; 'if the illness is not visible to others, does it exist?'; and 'handling life while hoping for a better future'. The subthemes reflect the experience of social isolation, their own and others' understanding of the illness and hope for the future. Conclusions. Not being able to be with friends, or attend school, made the adolescents feel different and forgotten. They felt alienated in their own bodies and were struggling to be visible to themselves and to their surroundings. Spending less time with friends and more time with their parents constituted a threat to independence and development. Yet they managed to envision a better future despite all the difficulties. Relevance for clinical practice. To provide effective support and constructive relations to adolescents with chronic fatigue syndrome, all health professions involved need insight from the persons who are themselves ill. Health centres could function as resource centres for patients and healthcare professionals.

    Health related quality of life in adolescents with chronic fatigue syndrome: a cross-sectional study2015In: Health and Quality of Life Outcomes, ISSN 1477-7525, E-ISSN 1477-7525, Vol. 13, article id 96Article in journal (Refereed)
    Abstract [en]

    Aim: To study health related quality of life (HRQOL) and depressive symptoms in adolescents with chronic fatigue syndrome (CFS) and to investigate in which domains their HRQOL and depressive symptoms differ from those of healthy adolescents.

    Background and objective: Several symptoms such as disabling fatigue, pain and depressive symptoms affect different life domains of adolescents with CFS. Compared to adolescents with other chronic diseases, young people with CFS are reported to be severely impaired, both physiologically and mentally. Despite this, few have investigated the HRQOL in this group.

    Method: This is a cross-sectional study on HRQOL including 120 adolescents with CFS and 39 healthy controls (HC), between 12 and 18 years. The Pediatric Quality of Life Inventory (TM), 4.0 (PedsQL) was used to assess HRQOL. The Mood and Feelings Questionnaire assessed depressive symptoms. Data were collected between March 2010 and October 2012 as part of the NorCAPITAL project (Norwegian Study of Chronic Fatigue Syndrome in Adolescents: Pathophysiology and Intervention Trial). Linear and logistic regression models were used in analysis, and all tests were two-sided.

    Results: Adolescents with CFS reported significantly lower overall HRQOL compared to HCs. When controlling for gender differences, CFS patients scored 44 points lower overall HRQOL on a scale from 0-100 compared to HCs. The domains with the largest differences were interference with physical health (B = -59, 95 % CI -54 to -65) and school functioning (B = -52, 95 % CI -45 to -58). Both depressive symptoms and being a patient were independently associated with lower levels of HRQOL

    Conclusion: The difference in HRQOL between CFS patients and healthy adolescents was even larger than we expected. The large sample of adolescents with CFS in our study confirms previous findings from smaller studies, and emphasizes that CFS is a seriously disabling condition that has a strong impact on their HRQOL. Even though depressive symptoms were found in the group of patients, they could not statistically explain the poor HRQOL.

    Current Practice in Mobile Learning: A Survey of Research Method and Purpose2009In: Proceedings of the 8th World Conference on Mobile Learning / [ed] Metcalf, D., Hamilton, A., Graffeo, C., 2009, p. 103-111Conference paper (Refereed)
    Abstract [en]

    In this paper we present a survey of published research in mobile learning. We investigated 76 papers from mLearn 2007 and 2008, and classified them according to two dimensions: research method and research purpose. Research methods and purposes are important parts of how research is conducted. Alas, opinions and approaches towards research differ greatly. The classified papers are evenly distributed among the research methods investigated, with one exception, being few in Basic research. In terms of research purpose, papers aimed to describe were well represented while there was a lack of papers targeting evaluation. Papers recounting both Basic research and research done to evaluate are imperative since they help a research field to mature and also help researchers to avoid repeating known pitfalls. This maturity, in turn, will lead to better scalability and sustainability for future research efforts in the community of mobile learning.

    The Quest for Equilibrium: Towards an Understanding of Scalability and Sustainability for Mobile Learning2008Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The research presented in this thesis investigates the concept of sustainability in relation to mobile learning initiatives. Sustainability is seen as a key concept for mobile learning to gain acceptance. In linking sustainability to scalability, a term used to describe how well something can grow to suit an increasing complexity, a representation of this process is provided. In this thesis, this process is called ``the quest for equilibrium.''

    A study was conducted of an actual mobile learning initiative that involved introducing podcasts as a supplement to traditional lectures in higher education. In following this initiative, thorough data gathering was conducted, utilizing the process of iterative cycles that characterizes the action research approach. In accordance, a literature survey was conducted, whereby leading publications in mobile learning were classified and analyzed according to the following criteria: Reflections, Frameworks, Scalability, and Sustainability.

    As the mobile learning system evolved from idea to an actual empirical study, trying to understand this process became important. The insights gained during this research were used to develop a conceptual model that is based on the notion that the two concepts of Scalability and Sustainability can be linked to each other.

    This conceptual model is presented describing how a mobile learning system evolves, from Idea, to Experiment, to Project, to Release. Further, each of the stages in this evolution is described by using four areas of concern: Technology, Learning, Social, and Organization.

    Using the experience from a specific mobile learning initiative to define a conceptual model that then is used to describe the same initiative, was a way to bring together practice, theory, and research, thus provide reliable evidence for the model itself.

    The conceptual model can serve as a thinking tool for mobile learning practitioners, to help address the complexity involved when undertaking new efforts and initiatives in this field.

    Understanding Scalability and Sustainability in Mobile Learning: A Systems Development Framework2009Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The rapid development of mobile technologies combined with access to content almost everywhere and every time allows people to experience new situations regarding learning in a wide variety of situations. Mobile learning brings the promise of learning "on the move" by allowing learners to take control over time and space, thus making learning "more natural". The field of mobile learning has rapidly evolved in the last ten years and many initiatives have been conducted worldwide. However, research results indicate that few of these efforts have produced any lasting outcomes. It is evident that these initiatives are faced with inherently complex settings and that the outcomes might not live up to their prom- ises; will not be adopted and, hence, will not become sustainable.

    Many of the complex issues faced by mobile learning initiatives are similar to those faced by the development of information systems. This latest statement suggests that an improved development practice might hold one piece of the key to sustainable mobile learning. The aim of the research presented in this thesis is to investigate the relation between information systems development practice and mobile learning development; and if methods and models originated within information systems development can be used to strengthen mobile learning initiatives. In order to investigate this relation, this thesis studies several mobile learning initiatives with a particular focus on how and why development and research was initiated and conducted. Concepts found in mobile learning practices are strengthened by providing a theoretical perspective with roots in information systems development. The outcomes of the studies presented in this thesis indicate that the development practice of mobile learning initiatives can be redefined in order to achieve more sustainable results.

    The core of this thesis consists of eight peer-reviewed scientific publications that have been presented at different international conferences. Five of the papers explore the field of mobile learning and its practice while the other three publications present the central ideas that serve as the basis for the proposed framework, how it has been developed, and the motivations behind its creation.

    The main contribution of this thesis is a novel development framework aimed at researchers and practitioners in the field of mobile learning. The framework defines the life-cycle of a mobile learning initiative and identifies the importance of emphasizing the concepts of scalability and sustainability during the development process. This may be a way to reduce the complexity inherent to mobile learning and its settings, and a means to improve the outcomes of coming mobile learning initiatives in terms of long lasting usable results.

    Was it Pod Worthy?2007In: Proceedings of 30th Information Systems Research Seminar in Scandinavia, Department of Computer Sciences, University of Tampere, Finland , 2007, p. 10-Conference paper (Refereed)
    Abstract [en]

    Students and teaching staff in higher education are constantly looking for new tools to help them study and teach more efficiently. The University of Canterbury began ProjectPodcast to introduce podcasting to a number of subjects as an add-on to the current course curriculum. Podcasting is being used to enhance mobile learning and enthuse both students and lecturers. Previous podcasting evaluations show that there exists a need for both audio content from lectures, or so called “LectureCasts” as well as supplementary material or “Sup!Casts”. In this study, the evaluation of ProjectPodcast will be performed in-house. We have chosen an established six step methodology to avoid criticisms that often arise when evaluations are performed by internal members of the project. The evaluation is aimed at both the student population as well as the lecturing staff in order to gain knowledge about their impressions of podcasting. Prior podcasting

    surveys have received low response rates, due to the choice of time, location and medium. Hence, our evaluation plan has been created with the goal of encouraging feedback from students and lecturers. In this paper we present our preparatory plan for evaluating ProjectPodcast.

    Podcasts as a Supplement in Tertiary Education: An Experiment With Two Computer Science Courses2009In: Podcasting in Education / [ed] Mahashabde, K.E., India: ICFAI Books , 2009, 1Chapter in book (Other academic)
    Abstract [en]

    The current generation of undergraduate students are enthusiastic adopters of mobile technologies, and some of these technologies offers significant opportunities for broadening the times, places and manner that students study and learn. One of these is podcasting, which greatly eases distribution of content to portable devices, giving the students opportunity for anytime, anywhere learning. However, most educational podcasts do not take advantage of the potential of podcasting. In this paper we discuss the issues surrounding the use of podcasting for higher education. We report our experiences using podcasts to supplement two undergraduate Computer Science courses, and we provide tips for others considering the use of podcasts in education.

    A Framework to Guide and Structure the Development Process of Mobile Learning Initiatives2010In: Proceedings of the 9th World Conference on Mobile Learning, 2010, p. 184-191Conference paper (Refereed)
    Abstract [en]

    Mobile learning has yet to move on from small-scale trials to sustained deployment. One reason for this is the highly complex and multi-disciplinary setting that the initiatives operate within. They must deal with a wide range of issues such as software, hardware, people, learning, organizations and so on. At the same time, there is little support. Few frameworks to guide the development process exist. This article presents one such framework that was developed based on theories from software and systems development as well as practical experience from mobile learning. The framework divides the development into four Areas of Concern and introduces a life cycle of the mobile learning initiative. It further offers means to guide the development of the initiative and to find key issues that needs to be addressed in order to achieve sustainability. The framework presents a holistic view of mobile learning and is designed as an aid to all practitioners in mobile learning, no matter their background.

    A Meta-model Describing the Development Process of Mobile Learning2009In: Advances in Web Based Learning: – ICWL 2009 / [ed] Spaniol, M., Li, Q., Klamma, R., and Lau, R., Berlin / Heidelberg: Springer , 2009, p. 454-463Chapter in book (Refereed)
    Abstract [en]

    This paper presents a meta-model to describe the development process of mobile learning initiatives. These initiatives are often small scale trials that are not integrated in the intended setting, but carried out outside of the setting. This results in sustainability issues, i.e., problems to integrate the results of the initiative as learning aids. In order to address the sustainability issues, and in turn help to understand the scaling process, a meta-model is introduced. This meta-model divides the development into four areas of concern, and the life cycle of any mobile learning initiative into four stages. The meta-model was developed by analyzing and describing how a podcasting initiative was developed, and is currently being evaluated as a tool to both describe and evaluate mobile learning initiatives. The meta-model was developed based on a mobile learning initiative, but the meta-model itself is extendible to other forms of technology-enhanced learning.

    Addressing Sustainability for Research Initiatives in Mobile Learning through Scalability2009In: Proceedings of the 8th IASTED International Conference on Web-Based Education / [ed] Uskov, V., ACTA Press, 2009, p. 7-12Conference paper (Refereed)
    Abstract [en]

    Understanding research initiatives in the field of mobile learning involves dealing with complexity. It is important to gather knowledge on how to nurse these attempts. To develop ideas and reach wide deployment of novel mobile learning is of great value. In this paper there is a discussion of the factors that describe attributes of mobile learning research initiatives and an investiga- tion of whether these are sustainable or not, and what this means. Sustainability for mobile learning initiatives is essential for the wide acceptance from both public and academia. The paper also addresses scalability of mobile learning research initiatives. Scalability is a term used to describe how well something can grow to suit an increasing complexity, and is addressed as a possibility to reflect on good ideas. Scalability is important in order to reach sustainability. Finally, this paper introduces a model that illustrates the evolutionary life cycle of a mobile learning research initiative. The model presents four evolution stages and these are: Idea, Experiment, Project, and Release.

    Abstract [en]

    The notion of network structure for social relations dates back half a century. Nowadays people form social networks offline as well as online. At an online community people are connected trough information exchange of sorts. Interest groups form often forums to aid each other and discuss things. Programmers are no exception and a question and answer site called Stack Overflow has been up and running since 2008. Our focus is to find patterns of how people interact on this online community and see if we can find expert users. We find 4 different ways to categorize experts, which result in different rankings. We also investigate how expertise is divided among topics, and find some overlap with the global ranking.

    Bringing a Framework to Tackle the Development Process in Mobile Learning2009In: Proceedings of the 15th International Conference at Centre for Philosophy, Technology, and Social Systems / [ed] Basden, A., Haftor, D., and Grobler, L.M.J., 2009Conference paper (Refereed)
    Abstract [en]

    This paper presents a study that was conducted of the devel- opment process of an initiative that used podcasts (i.e., digital audio-files) to supplement lectures in higher education. A thorough data gathering was conducted using the iterative cycles of the action research approach. The empirical data was analyzed and this analysis resulted in a framework that shows how sustainability and scalability are linked. The framework also shows how an initiative is developed from Idea, to Trial, to Project, to Release, and how each of these stages can be described using four areas of concern, namely, Technology, Learning, Social, and Or- ganization. Using the experience from a specific mobile learning initiative to define a framework that is then used to conceptualize the development process is a way to bring together practice, theory, and research, and thus provide reliable evidence for the framework itself. The framework captures the development process and the relevant context in a unified theoretical attempt and is suitable for practitioners dealing with initiatives in the field of mobile learning.

    Dealing with Stakeholders in Mobile Learning: A Study of Three Initiatives2009In: Proceeedings of the 32nd Information Systems Resaerch Seminar in Scandinavia (IRIS'32) / [ed] Molka-Danielsen, J., Molde University College , 2009Conference paper (Refereed)
    Abstract [en]

    There is a need to reach viable design for initiatives in mobile learning and researchers are faced with a magnitude of factors to consider. The work to identify and access stakeholders and acknowledge their requirement is a difficult task. Most mobile learning initiatives often follow an evolutionary development process where the system is constructed, evaluated, and refined in increments. During this process, the stakeholders and their needs might change, so even if there was an initial understanding, it might not be correct after one or more increments. In this paper we studied three initiatives with a focus on how they dealt with stakeholders during the development process and finds that the three initiatives deal with stakeholders in an on-demand fashion. New groups of stakeholders are considered when needed, and this leads to a development process that is a mix between sequential and evolutionary, which results in inflexible system solutions. In order to improve on this, stakeholders need to be regarded in a more inclusive fashion, where they are considered as part of the entire development process.

    Extracting and expressing experience with mobile learning: lessons learned2010In: International Journal of Mobile Learning and Organisation, ISSN 1746-725X, E-ISSN 1746-7268, Vol. 4, no 4, p. 428-439Article in journal (Refereed)
    Abstract [en]

    Many published results in the field of mobile learning focus on isolated technology solutions or a specific trial rather than to reflect on the overall work practice and development process of whole initiative/s. Exchanging knowledge from past experiences is often done informally between researchers in mobile learning. Making the knowledge gained explicit is of great value, as it can provide a pre-understanding for others. This paper analyses and reflects on three mobile learning initiatives with respect to how these address technology, context and stakeholders. From this, six lessons are extracted: reuse as much as possible, consider how to work around bad/broken network connections, do not underestimate the need for data management, take advantage of situated learning, evaluate to validate the result and identify and include all stakeholders. These lessons can serve as considerations for researchers when undertaking new initiatives in mobile learning.

    Introducing Podcasts to the Educational Palette of a Dual-Mode Course2012In: Proceedings 2012 17th IEEE International Conference on Wireless, Mobile and Ubiquitous Technology in Education, WMUTE 2012, IEEE, 2012, p. 112-116Conference paper (Refereed)
    Abstract [en]

    Distance students can suffer from feelings of isolation, which can result in dropouts from lack of motivation to continue the course. Previous studies have shown that the use of podcasts can help reduce this feeling of isolation. Podcasts can also help make studies more flexible, which can aid students with a busy schedule. To evaluate podcasts in distance higher education, we provided the students with four types of podcasts: LectureCasts, TutorialCasts, ReviewCasts and ExtraCasts. We produced 54 podcasts during the course. The students perceived all of the types of podcasts helpful, but preferred the TutorialCasts. These focused on solving actual problems, and the students said that they learned a lot by these. We found that it takes a lot of resources to produce good podcasts and any attempt to introduce them should be budgeted accordingly. We also found that there are still several technical challenges to overcome, from local infrastructure to subscriptions models and device compatibility.

    Abstract [en]

    Incorporating knowledge from past experiences is an important part of any development process, as one has to know what worked and what did not in order to avoid repeating the same mistakes. However, many published results in the field of mobile learning focus on isolated technologies or a specific trial rather than to reflect on the overall work practice and outcome. Such reflections can offer maturity to this emerging field of research. This paper presents reflections gained from three mobile learning initiatives that are presented in the form of lessons learned. These lessons learned can serve as considerations for researchers when developing new initiatives.

    The Beginner’s Guide to ICT Context: A Theoretical Contribution Aimed for the Atypical Developer and Team2011In: Proceedings of the 34rd Information Systems Research Seminar in Scandinavia, 2011Conference paper (Refereed)
    Abstract [en]

    Many recent ICT development projects involve atypical de- veloper teams and practitioners that are domain experts, but not ex- perienced in information systems development. While domain experts usually participate in development projects, we find that many of them take a more active or even driving role in recent projects. This can pose a problem, since the common systems development methodologies are complicated and require training. They are also not designed for the level that these atypical teams and non-expert practitioners can benefit from. In this paper we formulate a framework based on personal experi- ence of several ICT development projects and a theoretical foundation in information systems development research. The framework is designed to be suitable and accessible by non-expert and to be able to serve as a platform for collaboration and communication. The framework divides the development process into four stages and four areas of concern. It also introduces a number of concepts, such as focus, scalability and equi- librium. A project scales from stage to stage, each focusing on a different area of concern.

    Thinking ahead in mobile learning projects: A survey on risk assessment2009In: Proceedings of the 8th International Conference on Perspectives on Business Information Research / [ed] Aidemark, J., Carlsson, S., Cronkvist, B., Kristianstad Academic Press , 2009, p. 57-66Conference paper (Refereed)
    Abstract [en]

    Mobile learning is an innovate and dynamic field of multi-disciplinary research and development. This paper presents a study of risk assessment in mobile learning. Interviews, a questionnaire, and several publications are used as means for data collection. This is done to identify risks within mobile learning projects in order to investigate how well these fit a risk assessment model for socio-technical systems. The survey of mobile learning projects show that the project managers are faced with an array of potential risks. The risks are then classified according to a model developed by Lyytinen et al., which is based on the influential Leavitt’s Diamond. The research finds that the model is sufficient to classify the risks experienced by mobile learning projects. It does provide a good starting point and when used it can quickly illustrate how the variables relates to each other. The complexity concerning risk management is important for the mobile learning community, and a model to proceed from might benefit the community greatly.

    Podcasts as a Supplementary Teaching Tool for Distance Education2011In: Proceedings of the 3rd International Conference on Education and New Learning Technologies, 2011, p. 4186-4194Conference paper (Refereed)
    Abstract [en]

    In this paper we describes an experiment we conducted to investigate how podcasts can be used as a teaching tool for distance education. Distance students have a higher drop-out rate and we wanted to aid them in managing the course load and have them complete the course on time. The course is a introduction to database technology and dual in the sense it combine distance and campus students. Most students claim they are short on time but this is especially true when it comes to distance students as they often have part or even full-time jobs. This results in them needing to have the flexibility to study on their own schedule but this also creates a sense of isolation as they are excluded from the community that is formed on campus.

    The campus lectures are offered as live streams and full recordings to the distance students so in our experiment we extend them with Lec- tureCasts, TutorialCasts and ExtraCasts. The LectureCast is an audio only version of the recorded lectures, the TutorialCast is an instructional podcast that shows how to solve a specific problem or use a specific tech- nology and the ExtraCast is extra, optional information related to the topic of the course.

    All in all, we produced 54 podcasts during the course and evaluated the process and the podcasts from a lecturer and student perspective. Students preferred the TutorialCasts and found that they learned a lot by watching these. From a lecture perspective, we found that while the TutorialCasts required some effort to record, the improved quality of the students’ hand-ins and reduced the number of revisions and questions. The students appreciated the ExtraCasts, but from a lecturer perspec- tive, we found that these require a lot of resources in planning and pro- duction so you need to budget this before hand. The students found the LectureCasts difficult to follow without video, but they require little effort to prepare, and it is possible to improve the understandability. Our experience from the podcast experiment can be summarized as fol- lows: it takes a lot of resources to produce good podcasts and any attempt to introduce them should be planned well in advanced and done in an iterative fashion, there are still several technical challenges to overcome, from local infrastructure to student subscriptions and device compatibil- ity, TutorialCasts proved to be a very effective addition to the Lecturer toolkit.

    We found that podcasts can help address these issues. Devices that can play audio and video podcasts are in wide use among our students, and offer the opportunity to study at any time and place. The podcasts allows the lecturers to relax both format and content, and to provide material that is suitable for different situations.

    A Metrics-Based Approach to Technical Documentation Quality2010In: Proceedings of the 7th International Conference on Quality of Information and Communications Technology, IEEE, 2010, p. 476-481Conference paper (Refereed)
    Abstract [en]

    Technical documentation is now fully taking the step from stale printedbooklets (or electronic versions of these) to interactive and online versions.This provides opportunities to reconsider how we define and assess the qualityof technical documentation. This paper suggests an approach based on theGoal-Question-Metric paradigm: predefined quality goals are continuously assessedand visualized by the use of metrics. To test this approach, we performtwo experiments. We adopt well known software analysistechniques, e.g., clone detection and test coverage analysis, and assess thequality of two real world documentations, that of a mobile phone and of(parts of) a warship. The experiments show that quality issues can be identifiedand that the approach is promising.Technical documentation is now fully taking the step from stale printedbooklets (or electronic versions of these) to interactive and online versions.This provides opportunities to reconsider how we define and assess the qualityof technical documentation.

    A Visualization-based Approach to Present and Assess Technical Documentation Quality2011In: Electronic Journal of Information Systems Evaluation, ISSN 1566-6379, E-ISSN 1566-6379, Vol. 14, no 1, p. 150-159Article in journal (Refereed)
    Abstract [en]

    Technical documentation has moved from printed booklets to electronic versions that need to be updated continuously to match product development and user demands. There is an imminent need to ensure the quality of technical documentation, i.e., information that fol- lows a product.

    In order to ensure the quality, it is important to be able to measure it in a constructively way. We approach technical documentation quality from a software quality perspective and rely on automated measurements and analyses. We acknowledge that it is not possible to assess quality attributes such as “ease of understanding” using automated measure- ments. We rely on visualizations as a communication medium between machines and humans, and define a visualization-based quality assess- ment approach for technical documentation.

    In order to test our approach, we use it to assess the quality of 3 real- world documentations from a Swedish mobile phone manufacture, a Japanese camera manufacture, and a Swedish warship producer. The study shows that our approach can be used to identify potential quality defects. For example, we tested an unclassified subset of the warship’s technical documentation and found that 49% of it was redundant text clones. We performed the study in collaboration with a Swedish company that is in charge of creating and maintaining the 3 documentations, and they acknowledge that our approach has great potential and that our results proved helpful to them.

    Information Quality Management: a Model-Driven Approach2012In: Proceedings of IRIS 2012, 2012Conference paper (Refereed)
    Abstract [en]

    Large amounts of information are produced on a daily basis. We include any form of electronic data in the term information, for example e-books, web sites, software, databases, etc. Several studies have investigated the quality of this information, and often find it lacking. It is a complex process of producing said information but also to define and assess quality of the information, especially across the many different forms. We present a model-driven approach to information quality management, were models and indicators are used to define and assess qual- ity. We rely on abstraction of models, which are described using meta model. We show how this model-driven approach is implemented by a software tool that (i) reads information, (ii) performs analyses on this information, and (iii) visualizes the results, to help stakeholders understand quality issues. The software tool has been used to evaluate the quality of real world software and docu- mentations.

    Incorporating Information Quality in Software Development2010In: Proceedings of the 33rd Information Systems Research Seminar in Scandinavia, 2010Conference paper (Refereed)
    Abstract [en]

    The usefulness and value of an information system is directly related to its perceived quality. Quality is multidimensional concept, and includes an object of interest, the viewpoint on that object and the qualities attributed to the object. This suggests that there is no universal standard in systems development; quality is rather defined how well the information system meets the purpose and the goals of the organization it is used within. It is important that people involved in a particular systems development project have an agreed understanding of what the strive for quality means. This agreed understanding should include how to assign appropriate quality characteristics to both the technical and social aspects of a system as well as how to assess and interpret them. The purpose of this paper is twofold; first, we emphasize that any definition of quality should be specific to a system, and include both the social and technical aspects of a system. Second, we extend methods used to define and assess quality to include social and technical aspects that extends beyond software. Our work is particularly focused on information quality.

    Information Quality Testing2010In: Proceedings of the 9th International Conference on Perspectives in Business Informatics Research, Springer, 2010, p. 14-26Conference paper (Refereed)
    Abstract [en]

    When a new system, such as a knowledge management system or a contentmanagement system is put into production, both the software andhardware are systematically and thoroughly tested while the mainpurpose of the system --- the information --- often lacks systemictesting. In this paper we study how to extend testing approaches fromsoftware and hardware development to information engineering. Wedefine an information quality testing procedure based on test cases,and provide tools to support testing as well as the analysis andvisualization of data collected during the testing. Further, wepresent a feasibility study where we applied information qualitytesting to assess information in a documentation system. The resultsshow promise and have been well received by the companies thatparticipated in the feasibility study. When a new system, such as a knowledge management system or a contentmanagement system is put into production, both the software andhardware are systematically and thoroughly tested while the mainpurpose of the system --- the information --- often lacks systemictesting.

    Context Thinking2008In: Proceedings of 31th Information Systems Research Seminar in Scandinavia, 2008, p. 15-Conference paper (Refereed)
    Abstract [en]

    The advancement of technology has had impact on almost all the aspects of human activities. Learning as one representative of these activities is going through changes as a result. For example, the use of mobile technologies and devices in the learning domain has lead to a magnitude of research, resulting in the field of mobile learning. Context plays a crucial role in any learning activity, and it is impossible to separate the participants, the technology, the activities and its focus, from the environment where it takes place. The focal point have been mostly on the technical side but as in all real-world situations, they exist in an inherently complex setting where social as well as personal implications comes to play an important part in order to reach sustainability. We believe that the lack of sustainability is a result of a barely existing holistic view of the educational situation and claim this complexity can be addressed with an extended view of context thinking. To accomplish this, we suggest a combination of hard and soft approaches, as practitioners need to become competent in context thinking from both perspectives.

    Analysis and Visualization of Information Quality of Technical Documentation2010In: Proceedings of the 4th European Conference on Information Management and Evaluation / [ed] Castro Neto, M, Academic Publishing International, 2010, p. 388-396Conference paper (Refereed)
    Abstract [en]

    Technical documentation has moved from printed booklets to online versions that need to be updated continuously to match product development and user demands. There is an imminent need to ensure the quality of technical documentation, i.e. information that follows a product.

    Moving from printed material to online versions also allows for documentation to become active, to integrate interactive content, which blurs the boundaries between information and software. In order to assess quality of technical documentation, we adopt analyses and visualizations known from quality assessment of software. The analyses assess text copies, usage, structural properties, and the conformance of information to meta-information. The analysis results are visualized using a range of abstractions to aid in identifying and communicating quality issues to different stakeholders.

    In a case study, we assessed the quality of real world technical documentations from a Swedish mobile phone vendor, a Japanese camera vendor, and a Swedish warship producer. The study showed that our analyses and visualization are applicable and can identify quality issues. For example, we tested an unclassified subset of the warship’s technical documentation and found that 49% of it was redundant information.

    The case study was conducted at a Swedish company that is in charge of creating and maintaining technical documentation. While our approach is limited to analysis that can be performed automatically, the company acknowledges that it has great potential and that our results proved helpful.

    Ultraprocessad mat: Sambandet mellan konsumtion av ultraprocessad mat, övervikt och fetma2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction. Ultra-processed food includes industrially produced food that often has a poor nutrition value but is high in energy density, e.g. soft drinks, candy, sweets, chips and pre-cooked food. Production, availability and marketing of processed foods and drinks has increased, which several researchers believe is the main reason for the obesity epidemic in the world. Previous research has shown an association between ultra-processed food and both overweight and obesity, metabolic diseases, cancer, depression and anxiety. Objective. The objective was to evaluate the association between ultra-processed food, overweight and obesity, and how the remaining diet is composed at an increased consumption of ultra-processed food. Method. The assignment is a literature review based on articles from the databases OneSearch and PubMed. Results. The results indicate an association between ultra-processed food, overweight and obesity. An increased consumption of ultra-processed food also results in an increased total energy intake, a decreased intake of protein, fibre and potassium and an increased intake of total fat, saturated fat, polyunsaturated fat, trans fat, cholesterol, total sugar and sodium. The consumption of ultra-processed food is higher among white/native, younger people, smokers, physically inactive and those with a lower degree of education. Discussion. The main reason of the result is believed to depend on the fact that a diet rich in ultra-processed food also is a diet rich in fat and sugar, which results in an increased total energy intake that results in weight gain.

    Utvärdering av skillnad i metod att mäta överrefraktion samt hur överrefraktionen skiljer sig mellan tre olika instrument2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte: Syftet för denna studie var att se om det var någon skillnad i den överrefraktion man får fram hos patienten när överrefraktionen genomförs i provbåge, foropter och autorefraktor. Undersökningen gick även ut på att se om det blev någon skillnad om överrefraktionen genomfördes monokulärt med ocklusion eller binokulärt med dimlins.

    Metod: I studien deltog 30 personer i åldrarna 19 till 42 år. Det var sammanlagt 13 lågmyoper, 3 högmyoper, 5 hyperoper och 9 emmetroper som deltog i undersökningarna. Av dessa var 8 personer inte linsbärare och blev tillpassade med linser utifrån k-värden och HVID för att få en så bra sits som möjligt på linserna. De andra deltagarna blev tillsagda att komma till undersökningen med linser ordinerade till dem av en leg. optiker. Linsernas styrka kontrollerades sedan i provbåge, foropter och autorefraktor i slumpmässig ordning för att inte mätmetoden skulle påverka resultaten. Det var även slumpmässigt om överrefraktionen började med att utföras monokulärt eller binokulärt. Resultaten från överrefraktionerna antecknades och deltagarnas linsstyrkor antecknades för att sedan sammanställas i resultaten.

    Resultat: Resultaten visade att det fanns en signifikant skillnad mellan överrefraktionerna i provbågen och autorefraktorn samt foroptern och autorefraktorn då sfärisk ekvivalens användes för resultaten vid autorefraktorn. Däremot var skillnaden mellan provbågen och foroptern inte signifikant. Vid jämförelse binokulärt och monokulärt hittades endast en signifikant skillnad då foroptern användes som instrument.

    Slutsats: Av studien kunde det konkluderas att överrefraktion i provbåge eller foropter var lämpligast att använda. Det var inte heller någon signifikant skillnad i överrefraktion genomförd monokulärt och binokulärt.
