    Från olycka till säker väg: En granskning av den svenska trafikolycksstatistiken2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The starting point for all road safety work in Sweden is based on a decision taken by the government in 1997. The decision included strategic long-term work, with the ethical approach that no one would have to die or be seriously injured in traffic. The focus was shifted to traffic accidents, but that the consequences for personal injuries would be reduced. The Swedish Transport Administration, which is responsible for approximately 100 000 kilometers of state roads, has developed a systematic way of working in order to realize the vision of the injury level in traffic accidents. By setting sub-goals, cooperation with other actors, developed indicators and annual analyzes, a method is created to monitor the results of different road safety measures. An important part of road safety work is the traffic accident statistics collected from the Swedish Traffic Accident Data Acquisition (Strada). The reporting to Strada is carried out by police and emergency care. The Transport Agency, which is responsible for Strada and Transport Administration, which is one of the users of traffic accident statistics, has highlighted the importance of this information in road safety work. Both actors have also stated that there are problems with reporting to Strada. In this degree project the problem is divided into two categories: loss and deviations. Loss is meant traffic accidents that are never registered in Strada. Deviations refer to incorrect information, based on the actual event, which is registered to Strada. The purpose of the thesis work is to study these two categories of problems, focusing on the police's reporting, and how they affect the Swedish Transport Administration's road safety work, primarily from a construction engineering perspective. The method of the investigative part has been divided into two parts. The first part is an interview study. People who are well-informed in the chain of events "From Accident to Safe Road" have been interviewed. Through the interviews, the problems and how they affect road safety work can be better explained. The second part consisted of a survey. The target group was the police who report traffic accidents on a daily basis. Deviations were identified by the survey. The study showed that there is a loss in police reporting to Strada, and there are different types of loss. The police in Dalarna report about 98 percent of the traffic accidents that are the responsibility of the police. Other loss is caught to some extent by the healthcare industry. There are deviations in the police's reporting. By other supplementary sources of information, these deviations are corrected to a certain extent. The problems do not primarily affect the Swedish Transport Administration's construction engineering aspects. The building engineering aspects are based on standard road construction with the functional objective as a first step. On the other hand, research on the basis of standardized roads can be affected. The priority for which roads should be addressed can also be influenced by loss and deviations.

    Exploring nursing-sensitive events in home healthcare: A national multicenter cohort study using a trigger tool2023In: International Journal of Nursing Studies, ISSN 0020-7489, E-ISSN 1873-491X, Vol. 138, article id 104434Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: The provision of home healthcare is increasing in response to the growing aging population with the need for chronic disease management in their homes. Safety work differs from hospital care. The incidence of adverse events in home healthcare is sparsely studied but is estimated to occur in-one third of patients, and most are deemed preventable. Although nursing care is crucial for risk assessment and preventive work in the home environment, the role of registered nurses in the prevention of no-harm incidents and adverse events has not received sufficient scientific attention.

    OBJECTIVES: To explore nursing-sensitive events in patients receiving home healthcare.

    DESIGN, SETTING AND PARTICIPANTS: A Swedish national multicenter study based on a structured record review of 600 randomly chosen healthcare records from 10 organizations in different regions of the country.

    METHODS: Ten trained teams, each including physician(s) and registered nurses, undertook a review based on the Global Trigger Tool method. The review covered a maximum of 90 days from admission to home healthcare. First, each record was screened for the presence of 38 predefined triggers. In the second step, every potential event was assessed according to preventability, types of events, severity, time of occurrence, consequences of the event, and potential contributing causes.

    RESULTS: In total, 699 events were identified in the study. Of these, 495 (74.0%) were classified as nursing-sensitive (227 no-harm incidents and 268 adverse events) and affected 267 (44.5%) patients, with a mean of 1.9 events per patient. The majority (n = 367, 73.1%) were considered preventable. The most prominent types of nursing-sensitive event were falls (n = 138, 27.9%), pressure ulcers (n = 62, 12.5%), healthcare-associated infections (n = 58, 11.7%) and medication management (n = 50, 10.1%). Concerning severity, 45.9% were classified as no-harm incidents and another 36.6% resulted in temporary harm that required extra healthcare resources: 226 hospital days, 66 physician visits in outpatient care, and 99 in home healthcare. All severity types occurred from day 1, except death, which included only one patient. The most frequent contributing factors were deficiencies in nursing care, treatment & diagnosis, with the subgroups nursing care, observation, treatment & follow-up, followed by deficiencies in the organization.

    CONCLUSIONS: Nursing-sensitive events in home healthcare are common, often preventable, and occur from the start of the care period. This study contributes to increased knowledge of patient safety shortcomings and points to the important role that registered nurses play in patient safety work.

    Forskning i samverkan: Att vara nära men se med nya ögon2018In: Utbildning och Lärande / Education and Learning, ISSN 2001-4554, Vol. 12, no 1, p. 87-101Article in journal (Refereed)
    Abstract [en]

    The purpose of this article is to investigate how collaborative research can be used to develop early interventions in preschool. The research has been conducted together with preschool heads, special educators and social educators in a small municipality. The initiative was taken by municipal managers. After the development work had started, researchers were invited to a collaborative research process that lasted for about two years. Data was collected through process meetings, critical incidents, interviews, surveys and group discussions.

    The process is characterized by phases where different staff groups were involved. Preschool teachers both stressed their own skills and also emphasized the importance of continuous support and guidance from special and social educators. Managers emphasized their increased overall skills about early interventions. Collaborative research has helped to structure, quality assure and anchor focus on early interventions. It has been a tool for highlighting the issue from different perspectives, when staff and researchers work together. It has helped paying attention to important aspects, suggesting new directions when needed. In the research process, social and special educators have received valuable support in their new roles in the preschool environment. When the research process was completed, permanent support for early interventions was implemented.

    Att arbeta med barnlitteratur och hur det motiverar eleverna: En litteraturstudie om användningen av barnlitteratur i engelskundervisningen i årskurs 1-32017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Barnlitteratur är ett vanligt förekommande inslag i den svenska skolan och används bland annat för att utveckla språket och för att få kunskap om världen. Syftet med denna litteraturstudie är att undersöka vad tidigare forskning säger om barnlitteratur och dess användning vid inlärning av engelska som andraspråk i årskurs 1-3, samt hur det kan främja elevernas motivation. Metoden för studien är en systematisk litteraturstudie med en kvalitativ innehållsanalys. Fem vetenskapliga studier rörande ämnet analyserades för att upptäcka mönster, samband eller skillnader. Resultatet visar att användning av barnlitteratur i engelskundervisning har många fördelar vid inlärning av engelska som andraspråk. Barnlitteratur ökar elevernas motivation, ordförråd, stimulerar fantasin och de får en större förståelse för omvärlden. Elevernas motivation kan enligt resultatet främjas på olika sätt men främst genom delaktighet och kommunikation. En slutsats som har dragits är att mer forskning inom ämnesområdet borde göras i Sverige så att fler lärare inser värdet av att använda barnlitteratur vid inlärning av engelska som andraspråk. Detta då det har visat sig vara en mestadels positiv effekt vid språkinlärning.

    Varför ser vi på tv-serier?: En kvalitativ undersökning om publikens känslor, motiv och relationer som uppstår2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie var att undersöka vad publiken känner när de ser på tv-serier och vad som motiverar publiken till att följa dem. Tillgången till tv-serier har ökat under de senaste åren på grund av internets utveckling och i takt med detta har också konsumtionen ökat. För att undersöka vad publiken har för känslor för de tv-serier de följer har kvalitativa intervjuer utförts med fem informanter som flitigt ser på tv-serier. Materialet har analyserats utifrån teorier om reception av film- och tv-tittande. Resultatet visade på att tv-serier får publiken att känna en samhörighet, eller en vänskap, till karaktärerna i sina tv-serier, det får dem att reflektera över sin tillvaro, fly verkligheten och samtidigt får tv-serier publiken att må bra. Dessa resultat kan vara motiv till varför publiken fortsätter att se på tv-serier, avsnitt efter avsnitt.

    "Bolagsverket är mer modernt än jag tänkte mig": Hur kan statliga myndigheter arbeta med Employer Branding för att attrahera Generation Y?2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction: Employer branding is a relatively new concept that has begun to be used as a strategy in Human Resource Management. By developing an Employer Brand, organizations can attract and retain talented workers and thus ensure their survival. However, there is no research on how employer branding can be used in the public sector to attract the newest gen-eration in the labor market; Generation Y.

    Objective: The purpose of this study is to increase understanding for how governmental em-ployers can work with Employer Branding to attract Generation Y.

    Method: The study is based on qualitative method and a phenomenological and deductive re-search approach. Research design was in the form of a case study. Nine semi-structured inter-views were conducted with respondents from Swedish Companies Registration Office, four interviews with people who work with Employer Branding and five who belong to Generation Y.

    Theories: "Employer Branding Predictive Model"

    Conclusions: The study reveals that the governmental employer is attractive to Generation Y but could improve the external communication of its Employer Brand. Without an explicit tar-get group and a pronounced Employee Value Proposition, the external communication is un-clear which reduces the employer's attractiveness to potential employees. The attractiveness arises only when the individuals from Generation Y already are recruited into the organization.

    Samhällskunskapslärares pedagogiska praktik i relation till deras uppfattning om syftet med samhällskunskap: en kvalitativ studie2022Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den här studien undersöker samhällskunskapslärares uppfattning av syftet med ämnet och deras uppfattning av sin pedagogiska praktik, samt hur lärarna uppfattar relationen mellan deras syn på syfte och pedagogiska praktik. Bakgrunden är en ämnesdidaktisk diskussion där lärares syn på vad eleverna ska använda kunskaperna till, har påverkan på undervisningens utformning. Med stöd av kvalitativa intervjuer från fem olika gymnasielärare i samhällskunskap, har intervjudata analyserats med hjälp av teori från John Dewey och Gert Biesta samt ämnesdidaktisk forskning inom samhällsvetenskap. Resultatet visar att lärarnas syn på samhällskunskapsämnet rör sig inom alla dimensioner av de humanistiska, demokratiska och ekonomiska bildningsidealen. Lärarna beskriver att syftet ska leda till att eleverna dels blir demokratiska samhällsmedborgare, dels förberedda för vuxenlivet. Uppfattningen av syftet motiveras av olika skäl, där styrdokument, källkritik och elevgruppens bakgrund, påverkar synen i olika grad. Lärarna motiverar sin pedagogiska praktik utifrån olika skäl där innehåll, kommunikation och bedömning tar sig mer eller mindre olika uttryck hos lärarna, kopplat till ämnets syfte. Resultatet visar att det kan finnas vissa samband mellan lärares uppfattning om syfte och deras val av pedagogik. Sambanden mellan syfte och praktik kan dock vara svåra för lärarna att se själva, men reflektion och diskussion underlättar att de medvetandegörs.

    The significance of patient participation in nursing care - a concept analysis2019In: Scandinavian Journal of Caring Sciences, ISSN 0283-9318, E-ISSN 1471-6712, Vol. 33, no 1, p. 244-251Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: The purpose of this study was to report on a concept analysis of the meaning of patients' participation. Participation is commonplace in many areas of health care and has become an important issue in healthcare services. Participation is essential when giving nursing care. Challenges exist throughout clinical practice to make the patient a participant in their own care. The study had a caring science perspective.

    METHOD: A literature study based on Walker and Avant's method was used with eight steps. Data were collected using several databases covering the years 1995-2017. The analysis covered fifteen articles, dissertations, reports and textbooks.

    FINDINGS: Patients' participation may be defined as a concept that relates to and includes the three caring science concepts: learning, caring relationship and reciprocity (defining attributes).

    CONCLUSION: Participation is a concept with vague meaning that is prevalent in nursing practice. Patients' participation is a complex concept. By using the attributes, it could be more visible in nursing care. The next question for research in this area is how these three attributes can best practically be achieved in a clinical context.

    Patientens delaktighet i val av vårdgivare. En litteratur review2018In: Nordisk tidsskrift for helseforskning, ISSN 1504-3614, E-ISSN 1891-2982, Vol. 14 årgang, no 1Article in journal (Refereed)
    Abstract [en]

    The idea behind care choice is that healthcare providers would be more responsive to patients' health problems and needs and in doing so compete with increased quality and that patients should be able to choose from this. The question is how patients choose a healthcare provider by themselves. The aim was to describe what affected when patients chose healthcare providers. A literature review was carried out. The results showed that patients' choice of healthcare providers depended on the following three themes: their own care experiences, caring relationships with staff and service provided by caregivers. The underlying idea of care choice is competition based on quality of care, but the results show that patients make their choices based on other factors as described in the result and therefore improvement can be achieved if focus is placed on being responsive for patient care needs.

    En vältränad och hälsosam kropp - eller bara en täckmantel för vad det egentligen handlar om?: En innehållsanalys av träningstidningarna Body och Fitness2005Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    The aim with this Essay is to examine the two most read magazines in Sweden covering the areas of exercising, fitness, bodybuilding, diets and “wellness” –Fitness and Body. Fitness’s target group is predominantly woman, while Body is almost exclusively read by men. The analysis is first done quantitatively, by systematically categorising the contents of the magazines. Then a qualitative analysis is made. Using two different theories, Anja Hirdman’s gender concept along with her constructivistic media perspective and the theory of Symbolic Interactionism, i try to answer the following questions; Does the two magazines term of address and language differ from one and other? And if that is the case, in what way? With point of departure from contents and subject areas, how are the two magazines compounded? How can the underlying message in the different articles be interpreted? The analysis shows that both magazines followed their purpose of writing about exercising in general, diet, fitness and bodybuilding. However, the magazine Fitness writes more often then Body about matters not following the given purpose, and the language in Body is more informative and general in comparison with the language used in Fitness. Still, the messages sent out by the different articles are in majority of the respects similar. Both magazines are portraying body ideals who can be understand as extreme. In Body the message feels fairly straight, “Build bigger muscles and burn more fat”, whereas Fitness willingly use the concept of “wellness” as a cover for what the message really is, namely “get your self a rock hard body through dieting and hard training”!

    We did it together: Fathers´ experiences of planned home birth in the Nordic countries2011Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [en]

    Sammanfattning: Bakgrund: för många pappor kan det vara en av livets största och bästa stund att närvara vid när deras barn föds. Det finns studier som beskriver pappors upplevelse av sjukhusförlossning, däremot finns det få studier som beskriver pappors upplevelse av planerad hemförlossning. Syftet med den här studien är att beskriva pappans upplevelser och erfarenheter av planerad hemförlossning. Metod: i denna studie medverkar 105 pappor från de nordiska länderna som har deltagit i planerad hemförlossning mellan 2009-2011. Materialet från en öppen enkätfråga analyserades med hjälp av deduktiv ansats. Den öppna frågan löd ”beskriv gärna förlossningen med egna ord”. Resultat: papporna upplevde den planerade hemförlossningen som lugn och säker, mycket tack vare den professionella barnmorskan och den välbekanta miljön. Att få vara hemma med sin partner och om så önskades, sin familj var högt skattat. Födelseprocessen hemma beskrevs av papporna som att ”vi gjorde det tillsammans” och ”det var vår egen förlossning”. Papporna uttryckte delaktighet i förlossningsflödet. De kände också att de fick ett barn och var en del av en vacker förlossning full av kärlek. Konklusion: att välkomna ett barn hemma i en lugn miljö där paret känner sig trygga och ostörda, kan underlätta en positiv och meningsfull förlossningsupplevelse.

    Lärarnas egna ord angående läraryrket: En studie om hur svenska och bolivianska lärare i grundskolans tidigare år ser på sitt yrke2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I dagens samhälle tycks alla ha en åsikt om skolan, och den får ofta utstå kritik, men sällan lyfts lärarnas perspektiv fram. Syftet med den här undersökningen är att ta reda på hur några lärare i grundskolans tidigare år i Sverige och Bolivia ser på sitt eget yrke och upptäcka likheter och skillnader mellan de två länderna. Frågeställningarna som användes var: Vad innebär det att vara lärare i respektive land? Vilka fördelar respektive nackdelar ser lärarna med sitt yrke? Vilka möjligheter att påverka sin egen arbetssituation och yrkets utveckling anser sig lärarna ha? Vilka skillnader och likheter finns mellan lärare i Sverige och Bolivia angående synen på sitt yrke? Till denna undersökning har åtta klasslärare i skolår 1-6 valts ut, hälften verksamma i Sverige och hälften i Bolivia. De arbetar på fyra skolor, belägna i fyra olika kommuner. För att uppnå syftet genomfördes intervjuer enskilt med varje lärare. Resultatet av undersökningen visar att de intervjuade lärarna anser att vara lärare innebär att undervisa, att fostra barn, att hålla många bollar i luften, att se till barnens bästa, och att arbeta i offentlighetens ljus. Fördelarna med läraryrket är, enligt dem, glädjen som eleverna förmedlar, och tillfredsställelsen de känner när en elev lyckas, samt tjusningen i att aldrig veta vad som kommer att hända. Nackdelarna kan sammanfattas som att man inte alltid får möjligheterna att hjälpa eleverna att lyckas. Lärarna känner att de påverkar vad som sker i klassrummet, fastän de är styrda av centralt beslutade dokument. Likheterna i synen på sitt yrke består av glädjen att arbeta med barnen och omtanken om dem, vikten av att kunna kontrollera dem samt att känna att man gör skillnad. Skillnaderna i synen grundas i de skilda ekonomiska förutsättningarna som lärarna i de två länderna har, samt att de svenska lärarna ser tidsbristen som ett stort problem, vilket de bolivianska inte nämner. Min slutsats är att lärarna har en varierad syn på sitt yrke samtidigt som de delar åsikt gällande många aspekter av yrket, trots att de arbetar under vitt skilda förhållanden.

    ASL – framtidens val vid läs- och skrivinlärning?: Studie av hur arbetssätten ASL och Phonics kan hjälpa och motivera elever i sin läs- och skrivinlärning.2016Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Skolan har en stor utmaning, i att hänga med i aktuell forskning, kring läs- och skrivinlärning. Men även vad gäller den tekniska utvecklingen, kring IKT. Det är inte helt lätt, att välja bästa pedagogiska metod, som finns tillgänglig. Dessutom behöver skolan fundera, på frågor kring sitt ansvar, och utjämna digitala ojämlikheter. ASL, Att skriva sig till läsning, är en inlärningsmetod som blivit populär i skolan. Den har delvis annan pedagogik än Phonics, traditionell ljudningsmetod. Men är ASL framtidens arbetssätt, när det gäller bra läs- och skrivutveckling? Syftet med studien är att empiriskt undersöka detta. Därmed besvaras frågeställningarna, om metoden kan höja elevers motivation, och lärande i läs- och skrivutvecklingen. Studien tar hjälp av befintlig forskning på området, tillsammans med nytt empiriskt material, i form av sex kvalitativa inter-vjuer. Forskningsbakgrunden redogör för tidigare forskning, kring metoderna ASL och Phonics, kopplat till läs- och skrivinlärning. Metodavsnittet visar hur undersökningen gjorts, och arbetsgången vid inspelning av intervjuerna. Resultatdelen visar respondenternas svar, om de pedagogiska arbetssätten, och dess effekter på elevers inlärning. Resultatet visar, att det inte finns några entydiga bevis, för ökad inlärning, med hjälp av ASL. Men det är lättare, att skriva och läsa, med datorns hjälp. Datorer har positiva effekter, på motivationen, och den sociala förmågan. ASL har även påvisat goda effekter, vad gäller elever i behov av extra stöd. Vilket kan möjliggöra ökad inkludering i klassrummet.

    Tribological Evaluation of CVD- and PVD-Coatings for Wire Drawing Applications2008Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [en]

    Ovako Steel is one of the world’s largest manufacturers of ball bearing steel. In the manufacturing route of ball bearing steel, wire drawing is one of the important steps for the production of wire products. Wire drawing dies used in the production at Ovako in Hällefors are today made of cemented carbide. The aim of this study was to investigate the friction and wear characteristics of a number of CVD- and PVD-coatings, deposited on the Ovako steel grade Ovatec 677, in sliding contact with the steel grade Ovako 803 using pin-on-disc testing. Based on the results obtained from this pin-on-disc investigation, three coatings were chosen to be deposited on drawing dies made of Ovatec 677. An introductory study of cemented carbide dies indicated that the coating should have low friction in the lubricated contact, and preferably also under local dry contact conditions, with steel to reduce the frictional heat since thermal softening of the steel substrate must be avoided. It also showed that the coating should have a smooth surface topography in order to reduce the material pick-up tendency and adhesive wear of the coating material. The coating should also show a high wear resistance/cracking resistance, i.e. a combination of high hardness and toughness. With these requirements in mind, two different coatings, a PVD CrC/C-coating, a CVD TiC-coating and a dual-layer TiC/CrC/C-coating, were found to be the most suitable for deposition on wire drawing dies.

    Tribology in Metal Working2012Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis focuses on the tribological performance of tool surfaces in two steel working operations, namely wire drawing and hot rolling. In all forming operations dimensions and surface finish of the products are of utmost importance. Forming basically includes three parts – forming conditions excluded – that may be changed; work material, tool and (possibly) lubricant. In the interface between work material and tool, the conditions are very aggressive with – generally or locally – high temperatures and pressures. The surfaces will be worn in various ways and this will change the conditions in the process. Consequently, the surface finish as well as the dimensions of the formed product may change and in the end, the product will not fulfil the requirements of the customer. Therefore, research and development in regard to wear, and consequently tribology, of the forming tools is of great interest.

    The investigations of wire drawing dies focus on coating adhesion/cohesion, surface characteristics and material transfer onto the coated steel both in laboratory scale as well as in the wire drawing process. Results show that it in wire drawing is possible to enhance the tribological performance of drawing dies by using a lubricant together with a steel substrate coated by a polished, dual-layer coating containing both hard and friction-lowering layers.

    The investigations of hot rolling work rolls focus on microstructure and hardness as well as cracking- and surface characteristics in both laboratory scale and in the hot strip mill. Results show that an ideal hot work roll material should be made up of a matrix with high hardness and a large amount of complex, hard carbides evenly distributed in the microstructure. The surface failure mechanisms of work rolls are very complex involving plastic deformation, abrasive wear, adhesive wear, mechanical and thermal induced cracking, material transfer and oxidation.

    This knowledge may be used to develop new tools with higher wear resistance giving better performance, lower costs and lower environmental impact.

    Varför IKT och digitala hjälpmedel i skolan?: Litteraturstudie av olika arbetssätt och effekter på elevers motivation och lärande2015Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den snabba tekniska utvecklingen i samhället och arbetslivet innebär ett ökat krav på skolan, att hänga med i utvecklingen och använda den teknik som finns tillgänglig, för att kompensera digital ojämlikhet som uppstår. Nya lärmetoder har framkommit som förordar en annan pedagogik än den traditionella med papper och penna, men vad är då egentligen bra lärmiljö och vad är bra metoder för läs- och skrivutveckling? Syftet med denna litteraturstudie är att undersöka varför IKT och digitala hjälpmedel behöver användas i skolorna, och påvisa vilka metoder som kan höja elevers motivation och lärande i läs- och skrivutveckling. IKT som hjälpmedel kommer att studeras, för- och nackdelar på forskningsområdet och slutligen ett resultat kring effekterna av IKT i undervisningen och dess påverkan på inlärningsaktiviteter och elevers lärande. Studien tar hjälp av relevant befintlig forskning på området för att besvara frågeställningarna. Metoden är en litteraturstudie där sökning efter tidigare forskning och relevanta vetenskapliga artiklar skett med hjälp av olika databaser och sökord. Dessa redovisas under metodavsnittet. I forskningsbakgrunden finns styrdokumentens syn på informations- och kommunikationsteknik och vad det innebär för skolan och lärarna, dessutom historiska perspektiv på läs- och skrivinlärning, där traditionella metoder ställs mot nyare, med mer inriktning mot ett digitaliserat klassrum. I resultatdelen visas forskningsstudier kring olika pedagogiska arbetssätt och effekterna på elevers inlärning. Resultatet visar att det inte finns några entydiga bevis för ökad inlärning med hjälp av IKT. Traditionell inlärning, ljudningsmetoden med papper och penna, kontra nyare teknik, med olika datorprogram (exempelvis skolstil) och dess påverkan på elevers lärande, studeras närmare i nästa arbete.

    Syfte: Litteraturstudien undersöker varför skolan behöver använda IKT och digitala hjälpmedel. Dessutom studeras olika metoder och arbetssätt och deras effekter på elevers lärande och motivation när det gäller läs- och skrivutveckling. Studien tar hjälp av befintlig forskning för att beskriva hur skolans arbete med IKT ser ut och fungerar i praktiken och därigenom kunna besvara uppkomna frågeställningar.

    Problemformulering: Varför IKT och digitala hjälpmedel i skolan? Litteraturstudie av olika arbetssätt och effekter på elevers motivation och lärande.

    An investigation of worn work roll materials used in the finishing stands of the hot strip mill for steel rolling2012Conference paper (Refereed)
    Abstract [en]

    The surface failure characteristics of different work roll materials, i.e. High Speed Steel, High Chromium Iron and Indefinite Chill Iron, used in the finishing stands of a hot strip mill have been investigated using stereo microscopy, 3D optical profilometry, scanning electron microscopy and energy dispersive X-ray spectroscopy. The results show that the surface failure mechanisms of work rolls for hot rolling are very complex, involving plastic deformation, abrasive wear, adhesive wear, mechanical and thermal induced cracking, material transfer and oxidation. Despite the differences in chemical composition and microstructure, the tribological response of the different work roll materials was found to be strongly dependent on the material microstructure and especially the presence and distribution of microstructural constituents, such as the different carbide phases and graphite (in the case of Indefinite Chill Iron). Cracking and chipping of the work roll surfaces, both having a negative impact on work roll wear, are strongly influenced by the presence of carbides, carbide networks and graphite in the work roll surface. Consequently, the amount of carbide forming elements as well as the manufacturing process must be controlled in order to obtain an optimised microstructure and a predictable wear rate.

Despite the differences in chemical composition and microstructure, the tribological response of the different work roll materials was found to be strongly dependent on second phase constituents such as the size, morphology and distribution of different carbide phases and graphite (in the case of Indefinite Chill Iron) which was found to promote cracking. Cracking and chipping of the work roll surfaces, both having a negative impact on work roll wear, are strongly influenced by the presence of carbides, carbide networks and graphite in the work roll surface. Consequently, the amount of carbide forming elements as well as the manufacturing process must be controlled in order to obtain an optimised microstructure and a predictable wear rate.

    Microstructural, mechanical and tribological characterisation of roll materials for the finishing stands of the hot strip mill for steel rolling2013In: Wear, ISSN 0043-1648, E-ISSN 1873-2577, Vol. 307, no 1-2, p. 209-217Article in journal (Refereed)
    Abstract [en]

    The microstructure, mechanical and tribologicalproperties for three different materials, High Speed Steel, High Chromium ironand Indefinite Chill iron, used for hot strip mill work rolls have beenevaluated. Microstructural characterisation was performed using light opticalmicroscopy, scanning electron microscopy and energy dispersive X-rayspectroscopy. The mechanical and tribological properties were evaluated usingmicro Vickers indentation and scratch testing in combination with post-testmicroscopy. The microstructures of the investigated materials were found to berather complex with a number of secondary phases andalso materials with similar nominal composition display significant differenceswith respect to distribution, size and morphology of carbides. Scratch testing,including detection of friction coefficient, acoustic emission and penetrationdepth, gives valuable information concerning the mechanical and tribologicalresponse on a microscopic level of the investigated materials. Type,amount, distribution, size and morphology of the secondary phases in thematerials have a strong impact on the surface deformation and wear mechanismsduring scratching. Cracking and chipping are frequently observed in connectionto the ridges surrounding the scratches. However, cross-sectional analyses ofthe scratched microstructures reveal that cracking of the brittle carbidephases may extend to significant depths, >100 µm, reducing the mechanicalstrength of the material. Based on the results, it is believed that a moreisotropic microstructure, e.g. obtained via a powder metallurgy process, withfiner carbides would result in improved properties and performance in a hotrolling application.

    On the possibility to replace cemented carbide with CVD and PVD coated steel in wire drawing dies – A tribological investigation2009In: Wear of Materials, Las Vegas, 2009Conference paper (Other academic)
    Abstract [en]

    Cemented carbide is today the most frequently used drawing die material in steel wire drawing applications. This is mainly due to the possibility to obtain a broad combination of hardness and toughness thus meeting the requirements concerning strength, crack resistance and wear resistance set by the wire drawing process. However, the increasing cost of cemented carbide in combination with the possibility to increase the wear resistance of steel through the deposition of wear resistant CVD and PVD coatings have increased the interest for steel wire drawing dies during the last years. In the present study, the possibility to replace cemented carbide wire drawing dies with CVD and PVD coated steel drawing dies have been investigated by i) tribological testing, i.e. pin-on-disc and scratch testing, in combination with post-test observations of the tribo surfaces using scanning electron microscopy, energy dispersive X-ray spectroscopy and 3D surface profilometry and ii) steel wire drawing under full scale industrial conditions. In the tests a sodium stearate based soap was used as a lubricant. Of the CVD and PVD coatings evaluated in the tribological tests, a CVD TiC and a PVD CrC/C coating displayed the most promising results, i.e. a combination of high wear resistance and low friction in contact with the steel wire material and consequently these coatings were selected for the steel wire drawing tests. Post-test examination of the worn drawing dies showed that the CrC/C coating displayed a high wear rate while the TiC coating showed a low wear rate but also signs of local cracking and chipping. However, the overall best performance was displayed by a TiC – CrC/C dual layer coating which displayed a limited cracking and chipping tendency although the top CrC/C coating showed a high wear rate. Based on the results obtained, CVD and PVD coatings aimed to provide improved tribological performance of steel wire drawing dies should display a smooth surface topography, a high wear resistance, a high fracture toughness (i.e. a high cracking and chipping resistance) and intrinsic low friction properties in contact with the wire material. Also, the steel substrate used must display a sufficient load carrying capacity and resistance to thermal softening.

    Tribological testing of some potential PVD and CVD coatings for steel wire drawing dies2011In: Wear, ISSN 0043-1648, E-ISSN 1873-2577, Vol. 273, no 1, p. 55-59Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to investigate the possibility to replace cemented carbide wire drawing dies with CVD or PVD coated steel dies. Material pick-up tendency, friction and wear characteristics of four different commercial coatings – CVD TiC and PVD (Ti,Al)N, CrN and CrC/C – in sliding contact with ASTM 52100 bearing steel were evaluated using pin-on-disc testing. The load bearing capacity of the coating/substrate composites was evaluated using scratch testing. The results show that the friction characteristics and material pick-up tendency of the coatings to a large extent is controlled by the surface topography of the as-deposited coatings which should be improved by a polishing post-treatment in order to obtain a smooth surface. Based on the results obtained in this study, three different coatings – CrC/C, TiC and dual-layer TiC/CrC/C – are recommended to be evaluated in wire drawing field tests. CrC/C and TiC are recommended due to their intrinsic low friction properties and material pick-up tendency in sliding contact with steel. The dual-layer is recommended in order to combine the good properties of the two coatings CrC/C (low shear strength) and TiC (high hardness).

    Automatisering av test av legacysystem: Utmaningar och faktorer att beakta2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Information systems are used by most organisations today and are critical to the business. Many organisations got one or more legacy systems which have been used for a long period of time. Failures and disruption in these systems can lead to great consequences and it is important to test the systems to avoid them. Manual testing requires much resources. To automate the tests are a possibility and our partner in this study, Stora Enso Skog, wanted to look into the possibilities.The purpose of this study is to describe what challenges you meet when automating tests for legacy systems. The purpose is also to describe what factors you need to consider when implementing test automation. To do this we have used a case study and gathered data through interviews and study of documents. The interviews have been conducted with experienced experts within the testing area.Our conclusions shows that there are a number of challenges to consider when automating tests for legacy systems. The challenges include problems trying to automate some sort of tests for legacy systems due to the code being unstructured and not prepared for tests. There’s also a risk of spending too much resources in automating the tests instead of improving the systems.A number of factors to consider when implementing automated tests for legacy systems have also been found. Examples given are that automating tests can never fully compensate for a bad architecture and design. Focus should also be on the most important tests and start automating small parts. Also to improve the possibility to test in legacy systems instead of just adopting the testing tool to the system is to be considered.Finally we have noted that there are different types and levels of legacy systems and because of that challenges and factors to consider when automating tests may vary. Many challenges and factors presented in this study also applies to systems not considered legacy.

    Hur stöttar läromedel elevers förmåga att anpassa texter efter olika genrer?: En analys av hur genrer beskrivs i tryckta läromedel för svenskämnet i årskurs 7–92020Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den här studien har analyserat hur genrers typiska drag beskrivs i läromedel som kan användas i svenskundervisningen på högstadiet. Syftet med analysen har varit att synliggöra i vilken utsträckning elever stöttas i att anpassa texter för olika kommunikationssituationer utanför klassrummet. Svenskämnet ska bidra till att eleverna lär sig skriva olika slags texter för skilda syften, sammanhang och mottagare vilket innebär att eleverna måste utveckla flera förmågor för att förstå och anpassa texter efter olika genrer. Vilket läromedel eleverna möter i undervisningen och hur detta läromedel beskriver genrer kan påverka elevernas förståelse för genrers typiska drag i relation till faktorer som syfte, genresteg och läsare. Genom att använda genrepedagogiken som teoretiskt ramverk har studien kunnat analysera läromedlens beskrivningar av genrer. För att få fram ett urval av populära tryckta läromedel bland verksamma lärare i svenskämnet spreds en enkätundersökning i sociala medier. Läromedlen analyserades sedan med hjälp av kvalitativ textanalys som metod och studiens huvudsakliga resultat synliggör att läromedlen grundar sig i genrepedagogikens tankar om genrer. Studien har framförallt resulterat i två slutsatser som visar hur läromedlens beskrivningar stöttar eleverna i att anpassa de texter de skriver för olika kommunikationssituationer. Det handlar dels om hur läsaren beskrivs och dels om hur formen har ett stort utrymme i läromedlen. Studien har visat att det finns en motsättning i hur läsaren beskrivs i förarbetet och vem läsaren sägs vara i instruktionen för att anpassa texten efter genren. I två av läromedlen fastställer man att den slutgiltiga läsaren är någon innanför klassrummet, vilket kan påverka hur väl eleverna stöttas i att skriva för läsare utanför skolans värld. För det andra har studien visat att läromedlens beskrivningar av genrers typiska drag påverkar hur eleverna stöttas i att anpassa genrer efter olika kommunikationssituationer. Det betyder att eleverna främst stöttas i att förhålla sig till genrers typiska form framför det kommunikativa syftet, vilket i förlängningen också påverkar hur väl eleverna kan anpassa texter för olika kommunikationssituationer utanför klassrummet.

    Potential och risker i svenskämnets skrivundervisning: En litteraturstudie om skrivundervisning i grundskolans senare år2019Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    För att kunna vara delaktig i dagens samhälle krävs goda kunskaper i skriftspråket. De nationella provresultaten i svenska från läsåret 2017/2018 påvisar att störst andel av högstadieeleverna har svårt att nå målen i det delprov som testar skrivförmågan. De tycks därmed finnas ett intresse att undersöka skrivförmågan i grundskolans senare år. Genom att sammanställa de senaste 15 årens forskning ämnar föreliggande studie att synliggöra vilken potential och vilka risker som forskningen påvisar vad gäller skrivundervisningens innehåll, arbetssätt och syfte.

    Studiens resultat visar att det finns såväl potential som risker i skrivundervisningen. Gällande innehåll visar studien att berättande och beskrivande texttyper dominerar men att skrivundervisningen har potential att ge eleverna möjligheten att arbeta med olika texter inom dessa genrer. Skrivundervisningen visar potential genom att använda gemensamma arbetssätt och diskussioner i arbetet före och efter skrivandet. I relation till syfte finns en potential att bidra till att eleverna utvecklar kunskaper om olika texter som de sedan kan använda i den egna produktionen. Studiens resultat påvisar bland annat att en av skrivundervisningens största risker är att de texter som skrivs ofta saknar en koppling till omvärlden. Det bidrar till att eleverna inte utvecklar förmågan att ta hänsyn till en fiktiv mottagare i sitt skrivande. Ytterligare en av skrivundervisningens risker är att eleverna lämnas ensamma under skrivandet men även att lärares didaktiska beslut i undervisningen och förväntningar på elevers färdiga texter inte alltid stämmer väl överens. En annan risk är att skrivandets syfte kan tendera att sakna betydelsefulla kopplingar till elevernas identitet och personlighetsutveckling.

    En böjd stavdesigns påverkan på stakfasens egenskaper2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose statement

    The purpose of the study is to examine how the pole plant and pole phase are affected by using a pole of curved, compared to straight, design for double poling at high speed on roller skis at a treadmill. The following research questions have been examined:

     Does a curved pole design result in a pole plant further forward?

     Does a curved pole design result in a change in the absolute length of the pole phase?

     Does a curved pole design result in a change in the relative length of the pole phase?

    Methodology

    Ten male cross country skiers (age 25,3 ± 5,1 years, height 182,1 ± 8,6 cm, BW 78 ± 6,5 kg) took part in the study. The test subjects performed a Vmax-test double poling on roller skis on a treadmill, with straight and curved poles. Movement data was collected and analysed to examine potential differences regarding pole plant, pole phase, recovery phase and total cycle time.

    Results

    A significant difference was found regarding the pole plant, as a curved pole design resulted in a pole plant further forward compared to a straight design. No significant difference was found related to the pole phase, recovery phase or total cycle time.

    Conclusion

    The study shows that the path of the pole tip is moved forward when using poles of a curved design. There is no change in the pole phase, the recovery phase or the total cycle time, thus the length of the pole phase, absolute as well as relative, is unaffected by pole design when double poling.

    Softproof och färghantering i designprocessen: Från skärm till tryck2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Målet med detta examensarbete har varit att ge en överblick över de parametrar som påverkar möjligheten att upprätta ett färghanterat arbetsflöde. Ett färghanterat arbetsflöde ger möjlighet att förutsäga färgåtergivningen i trycksaker via softproof – skärmkorrektur. Examensarbetet belyser de problem och fallgropar som finns i arbetsflödet och hur de kan påverka relevansen för en bedömning av tryckresultat via softproof. Examensarbetet behandlar hur färgåtergivningen påverkas av betraktningsljus och omgivningsljus samt vikten av att arbeta med en kalibrerad bildskärm – en förutsättning för att kunna utföra en färgriktig softproof. Som utgångspunkt för examensarbetet har arbetsflödet på fyra företag i branschen använts och hur väl de uppfyller gällande standarder, ISO 3664 och ISO 12646. Genom ett visuellt test som utarbetats inom examensarbetet har arbetsmiljöns påverkan på färgseendet kunnat påvisas. Testet kan ge en vägledning om hur avvikelser från ISO 3664 och ISO 12646 i arbetsmiljön påverkar bedömningen av färger vid softproof och provtryck.

    Hantering av producentansvarsmaterial2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Nästan alla materialflöden har en startpunkt och en slutpunkt. I detta examensarbete, gjort i samarbete med AB Borlänge Energi, berörs dessa start- och slutpunkter i form av producentansvar och avfallshantering. Producenterna har ansvar för insamlandet av avfall rörande bland annat förpackningar och returpapper samt att utforma förpackningen på ett sådant vis att minsta möjliga miljöpåverkan förekommer. Om (Avfallsutredningen (SOU 2012:56), 2012) kommer fram till att kommunerna får överta insamlingsansvaret för producentansvarsprodukterna, kan det komma att förändra förutsättningarna för insamlingssystemens utformning och vilka insamlingsresultat som kommer ur dessa. Kommunerna kan stå i ett vägval hur dessa system i framtiden skall se ut och vilka konsekvenser detta kan få.

    I Borlänge kommun visar statistik från plockanalyser att det finns 43 procent returpapper och förpackningar i brännbar fraktion. Detta vill AB Borlänge Energi ändra på då detta ger en förhöjd kostnad för förbränning samt att det inte är miljömässigt försvarbart att energiåtervinna material som kan materialåtervinnas. Kommunen har även mål för avfallshanteringen i sin avfallsplan som bör uppfyllas. Beroende på vilket insamlingssystem som väljs i framtiden kan lösningen för detta se olika ut. Genom att studera andra kommuner i landet och intervjuat ansvariga för avfallsfrågor, antyder svaren att Borlänge kommun ger väldigt knapphändig information till hushållen om avfallssortering. En frekvent förekommande orsak till att vissa kommuner lyckas samla in stora mängder förpackningar och returpapper är, enligt de intervjuade personerna, lyckade informationskampanjer samt återkommande information och återkoppling. Vilka insamlingssystem som används har viss betydelse, men utan en aktiv information nås inte målen, oavsett system. Det går att urskönja en förbättrad insamlingsmängd med fastighetsnära insamling genom både optisk sortering och fyrfackssystem, men i första hand bör kommunens ansvariga se över sitt informationsflöde innan annan åtgärd görs.

    Idrott och hälsas ”moment 22” Om utsatthet i miljö och prestation: - En kvalitativ studie om elevers deltagande i ämnet Idrott och hälsa i åk 92016Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Pupils participation in Physical education is studied by examining students motives to their own and others involvement and how students themselves believe that participation can be increased. This study is based on interviews with ten students in grade 9. The interviews were conducted individually and in groups with questions of partial projective character, which means that the issue is not addressed directly to the individual. I mean this is one of the reasons why the results of this study are fruitful.

    The results if this study shows that students opportunities to succeed in education is crucial for their motivation, which affects participation. It is mainly about physical performances where students with different prerequisites mett and where they feel that there is a competitive element. While competitive element is a big reason why some pupils passive or non-participation, this works as a strong motivator for others.

    Changing rooms are pointed by the informants as an environment where students feel vulnerable. The interviews show that there is harassment and degrading treatment in this environment. The situation and the environment in the changing rooms is a factor that affects the participation of students mean the informants. Pupils say that they deliberately did not perform in class to not get sweaty because they then need to shower and to show their body. Separate dressing room is not an option for students when they mean that student is singled out by this and face higher risks of exclusion. Based on Bourdieu's theories of symbolic capital it is possible to interpret different attitudes in and around education as a way to safeguard their own status in the group. That students deliberately not taking part in the lesson should not be seen as they are for example not interested. Passive or non-participating is likely to put the student in a so called "Catch-22", a downward spiral that is difficult to get out from.

    Identifiering av lämpliga organisations- och ägarformer för Dalarnas Science Park2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Foundation Teknikdalen has ambitions to undergo a transition and become Dalarna's Science Park. In order to implement this, we need a basis for determining what organizational and ownership form as Dalarna's Science Park should have. The purpose is to identify which organizational and ownership forms that may be suitable for Dalarna's Science Park. The substrate must also account for appropriate funding opportunities that are associated with the various organizational and ownership forms and how regional cooperation should occur in Dalarna's Science Park. The regional cooperation which can be found in the Dalarna's Science Park is bounded in this work to the cooperation between the business community and high school, with a Science Park as a potential node.

    Through surveys, interviews with representative from Science parks in Sweden and key persons in Dalarna, materials were gathered that later could be analyzed with consideration to the works purpose and where Stiftelsen Teknikdalen is today. Depending on what Dalarna Science Park wants to achieve, there are different paths to go when it comes down to organization- and ownership form. Dalarna Science Park is going to operate regional and with that considered it indicates that a limited company is the most suitable organization form for them, based on the collected material. One of the pros is the clearness in ownership and controlling that a limited company provides in proportion to the remaining alternatives.

    There are several different forms of ownership, which could be suitable for Dalarna Science Park, where several of the options are advantageous. Stiftelsen Teknikdalens transformation should be based on its purpose, to enhance regional growth and development, and then consider which ownership that best meets this objective. The important thing is that the valleys Science Park has a base funding for their activities in order to be able to operate in the long term. Financial form of a Science Park is linked to the Organization and owner form, so the ratio of core funds and project funding in Dalarna's Science Park should be, should be clarified before an organization of choice can be implemented.

    The choosing of which organization- and ownership form can come to affect collaboration opportunities with Högskolan Dalarna, to mention one. To be able to be the link between the academia and the business world, Dalarna Science Park should weigh which organization- and ownership form is the most suitably by a Triple Helix view, in other words the collaboration between business world, body politic/authority and college/university.

    Yrkeselevers motivation till ämnet matematik på gymnasienivå: Finns det skillnader mellan olika yrkesprogram?2016Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Yrkesprogram är den del av gymnasiet som uppvisar störst andel elever med det underkända betyget F i matematik. Men även mellan de olika yrkesprogrammen finns det skillnader. Syftet med denna undersökning är att få en förståelse för elevers motivation för ämnet matematik inom yrkesprogrammen. Finns det skillnader mellan olika program och möjliga orsaker? Undersökningen genomfördes genom gruppintervjuer där elever från El- och energiprogrammet, Handels- och administrationsprogrammet samt Bygg- och anläggningsprogrammet deltog. Gruppintervjuerna genomfördes program för program och Peter Kloostermans intervjuverktyg användes. Resultatet visade på ganska stora skillnader mellan de deltagande programmen i vissa aspekter. Utifrån resultatet fördes diskussion som pekade på att det kunde vara kulturella aspekter som låg bakom skillnader på motivation mellan de olika programmen. Även studieteknik kan påverka motivationen för ämnet matematik.

    Kvinnors upplevelse av vård i samband med förlossning och eftervård: Kvalitativ innehållsanalys med fritextsvar från graviditetsenkäten2024Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: In order to have a positive experience of childbirth and aftercare, there is several factors that play a role in the outcome. Negative experiences increase the risk of future long-term complications with mental illness. The quality of care plays a major role and is based on the outcome of the care provided. Midwives in Sweden work with the normal process during childbirth and promote a physiological birth. Care during childbirth needs to be person centered and aftercare aims at caring for the woman giving birth but must also take care of the needs of the new family. The aftercare and follow-up that is offered varies around the country depending on regional routines. The framework “Quality maternal and newborn care “ was applied in the study. Aim: The purpose of the study is to investigate women´s experience in quality of care during childbirth and aftercare, in order to identify potential improvements. Methods: A qualitative method has been used to analyze open-ended answers from “Graviditetsenkäten” in two regions with a retrospective cross-sectional design. Results: The results were compiled into subcategories which were sorted under main categories based on a chosen framework. In total, the study included 14 subcategories which were applied in the categories: Practice Categories, Organization of Care, Values, Philosophy and Care Providers. Conclusion: The study confirmed both positive and negative experiences of care in childbirth and aftercare. The women in the study described various suggestions for improvement. The study is considered valuable and contributes to the possibility of future improvement within regional health services. Clinical implications: Care needs to become more person-centred and accessible in childbirth and aftercare. The greatest potential for improvement has been noticed in aftercare, which results in demands on the organization and the need for increased resources, but also a high level of competence of the care providers.

    Förutsättningar för en framgångsrik skrivundervisning i svenska på gymnasiet och högstadiet: En litteraturstudie2021Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The art and rules of traditional writing created by earlier generations is not always easy for the youth of today to understand and see the meaning of. Writing a Twitterpost or sending an SMS message seems to be the most common writing skills needed outside of the school buildings. The questions that this study seeks to answer is what kind of problems are connected to improving the students writing skills on the Swedish high school levels and how these problems can be solved? The focus of modern day Swedish language teaching has been removed from grammar and spelling to instead be focused on the content of the text. Writing an interesting story is more important than using the right grammar or spelling it correctly. The result shows that one of the main reasons for the writing deterioration is the lack of writing and grammar teaching. Many students have problems because of this when entering the university level where it´s taken for granted that the student knows the basic rules of writing and spelling. Some authors referred to in this study simply suggest that we go back to a writing correctly focused teaching again, but that is not the only thing suggested. The problem simply does not have just one solution but a diversity of different methods needs to work together to come up with the wished for result of a successful reading and writing education in the school of today.

    Att bygga sociala relationer i en eTjänstekontext2009Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Amergo är ett företag som inriktar sig på att köra ut bland annat frukt och fika till dess kundföretag. I dagsläget utför kundföretagen beställningar via telefon eller e-post. Jag har fått i uppgift att utveckla ett webbaserat IT-system som ska ge kundföretagen möjlighet att utföra och ändra sina beställningar utan Amergos direkta inverkan. Under systemutvecklingens gång har jag tagit Hultgrens (2007) teorier om eTjänster till hjälp för att på ett systematiskt sätt analysera systemet, eller eTjänsten. Denna analys resulterade i en rad frågeställningar vilka är tänkta att vara till hjälp vid vidareutvecklingen av eTjänsten. Därefter har jag, med hjälp av ovan nämnda frågeställningar, analyserat hur eTjänstens relationer kan byggas ut genom att tilläggstjänster skapas.

    Conceptual Product Development in Small Corporations2010Licentiate thesis, monograph (Other academic)
    Abstract [en]

    The main objective of the thesis “Conceptual Product Development in Small Corporations” is by the use of a case study test the MFD™-method (Erixon G. , 1998) combined with PMM in a product development project. (Henceforth called MFD™/PMM-method). The MFD™/PMM-method used for documenting and controlling a product development project has since it was introduced been used in several industries and projects. The method has been proved to be a good way of working with the early stages of product development, however, there are almost only projects carried out on large industries which means that there are very few references to how the MFD™/PMM-method works in a small corporation. Therefore, was the case study in the thesis “Conceptual Product Development in Small Corporations” carried out in a small corporation to find out whether the MFD™/PMM-method also can be applied and used in such a corporation. The PMM was proposed in a paper presented at Delft University of Technology in Holland 1998 by the author and Gunnar Erixon. (See appended paper C: The chart of modular function deployment.) The title “The chart of modular function deployment” was later renamed as PMM, Product Management Map. (Sweden PreCAD AB, 2000). The PMM consists of a QFD-matrix linked to MIM (Module Indication Matrix) via a coupling matrix which makes it possible to make an unbroken chain from the customer domain to the designed product/modules. The PMM makes it easy to correct omissions made in creating new products and modules. In the thesis “Conceptual Product Development in Small Corporations” the universal MFD™/PMM-method has been adapted by the author to three models of product development; original-, evolutionary- and incremental development. The evolutionary adapted MFD™/PMM-method was tested as a case study at Atlings AB in the community Ockelbo. Atlings AB is a small corporation with a total number of 50 employees and an annual turnover of 9 million €. The product studied at the corporation was a steady rest for supporting long shafts in turning. The project team consisted of management director, a sales promoter, a production engineer, a design engineer and a workshop technician, the author as team leader and a colleague from Dalarna University as discussion partner. The project team has had six meetings. The project team managed to use MFD™ and to make a complete PMM of the studied product. There were no real problems occurring in the project work, on the contrary the team members worked very well in the group, having ideas how to improve the product. Instead, the challenge for a small company is how to work with the MFD™/PMM-method in the long run! If the MFD™/PMM-method is to be a useful tool for the company it needs to be used continuously and that requires financial and personnel resources. One way for the company to overcome the probable lack of recourses regarding capital and personnel is to establish a good cooperation with a regional university or a development centre.

    Are empathy and compassion bad for the professional social worker?2014In: Advances in Social Work, ISSN 1527-8565, Vol. 15, no 2, p. 294-305Article in journal (Refereed)
    Abstract [en]

    Recent studies have shown that social workers and other professional helpers who work with traumatized individuals run a risk of developing compassion fatigue or secondary traumatic stress. Some researchers have hypothesized that helpers do this as a result of feeling too much empathy or too much compassion for their clients, thereby implying that empathy and compassion may be bad for the professional social worker. This paper investigates these hypotheses. Based on a review of current research about empathy and compassion it is argued that these states are not the causes of compassion fatigue. Hence, it is argued that empathy and compassion are not bad for the professional social worker in the sense that too much of one or the other will lead to compassion fatigue.

    Butler's stone and ultimate psychological hedonism2013In: Philosophia, ISSN 0048-3893, E-ISSN 1574-9274, Vol. 41, no 2, p. 545-553Article in journal (Refereed)
    Abstract [en]

    This paper discusses psychological hedonism with special reference to the writings of Bishop Butler, and Elliott Sober and David Sloan Wilson. Contrary to philosophical orthodoxy, Sober and Wilson have argued that Butler failed to refute psychological hedonism. In this paper it is argued: (1) that there is a difference between reductive and ultimate psychological hedonism; (2) that Butler failed to refute ultimate psychological hedonism, but that he succeeded in refuting reductive psychological hedonism; and, finally and more importantly, (3) that Butler's criticism of reductive hedonism can be used as a stepping-stone in another argument showing the implausibility of ultimate psychological hedonism as well.

    Compassion - a resource or threat for the professional social worker?2011In: The 2011 Joint Nordic Conference on Welfare and professionalism in Turbulent Times, Reykjavik, 2011Conference paper (Other academic)
    Abstract [en]

    What is the proper place of compassion within social work? Should social workers feel compassion for their clients, or is this something that should be avoided? Opinions differ. While some have claimed that compassion should be avoided in favor of a more detached and professional approach, others argue that compassion is an important, and unavoidable part, of a proper working-alliance. While some claim that compassion can be beneficial for the client, recent studies have suggested that too much compassion can lead to so-called compassion fatigue and be detrimental for the professional. If we want to assess these claims, we must first consider what compassion is. That is the purpose of this study. The aim is to gain a better understanding of what compassion is, with a special eye to the question as to whether compassion is a resource or threat within professional social work. Methods include conceptual analysis and phenomenological descriptions of compassion and related phenomena. The results can be summarized in two main claims. The first is that compassion is a particular kind of suffering directed towards the suffering of someone. What is special about compassion is that it is a suffering for another person’s sake: When you feel compassion (and only compassion) for another person, then you suffer over her suffering for her sake and not your own sake. The second claim is that compassion in and of itself is not harmful to the person feeling it. Although compassion consists in suffering, since it is a suffering for another person’s sake, a person feeling compassion is not, and does not take herself to be, the victim of something bad. It is an essential feature of compassion that if you feel compassion (and only compassion) for another person, then you take this person to be the victim of a harm but you do not take yourself to be so. In conclusion it is argued that these results point towards a more positive view of compassion and its place within social work.

    Abstract [en]

    Compassion is often described in terms of suffering. This paper investigates the nature of this suffering. It is argued that compassion involves suffering of a particular kind. To begin with a case is made for the negative claim that compassion does not involve an ordinary, or afflictive, suffering over something. Secondly, it is argued that the suffering of compassion is a suffering for someone else’s sake: If you feel compassion for another person, P, then you suffer over P:s suffering for P:s sake, and if that is all you do, then you are not affected with an afflictive suffering over something. The final section identifies and addresses a problem concerning self-pity, and a suggestion is made on how to specify the proposed account so as to cover both self-directed and other-directed compassion.

    Abstract [en]

    This paper compares the views on compassion in Spinoza, Hume and Schopenhauer. It is shown that even though all three approach compassion with the same aim and from very similar starting-points, all give significantly different accounts of compassion. The differences among the accounts are compared and explained, and it is shown how progress is made in that later accounts avoid certain problems faced by the earlier ones.

    Sjuksköterskans erfarenheter och attityder vid omvårdnad av personer som utsatts för våld i nära relationer: En litteraturöversikt2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Intimate partner violence is a major problem in society and a study showed that a third of all women who have been in a relationship at some point has been subjected to physical, psychological or sexual violence by their partner. The nurse is among the first to meet victims of intimate partner violence when they seek care and it`s therefore important that the nurse possesses the right knowledge.

    Aim: The aim with this literature review was to illuminate nurses' experiences and attitudes when caring for patients who have been subjected to intimate partner violence.

    Method: A literature review based on 14 scientific articles of both quantitative and qualitative approaches. The articles have been systematically searched through two databases focused on nursing research, available at Högskolan Dalarna.

    Results: Four main themes have been identified: Experiences in various healthcare contexts, Attitudes depending on context, Knowledge in relation to clinical experience and Obstacles and opportunities to offer help. These main themes have then been split up into several subheadings in the results. The nurses experienced difficulties maintaining a professional attitude towards the victims, and in many cases, they had a negative attitude and blamed the patients. The biggest obstacle nurses experienced was the lack of time and most of them felt that they needed more knowledge in the area.

    Conclusion: It is important that the nurse has knowledge of caring for people who have been subjected to intimate partner violence, maintains a professional attitude and disregards their own prejudices and opinions.

    Patienters upplevelser och livskvalité efter att ha överlevt ett hjärtstopp: En litteraturöversikt2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: In Sweden, approximately 10,000 people are affected by sudden cardiac arrest each year. Although survival has increased over the past decade, only 600 people out of these 10,000 survive. Cardiovascular disease is the leading cause of death in both men and women in Sweden. However, no underlying symptoms need to exist to suffer a sudden cardiac arrest, it can hit anyone, at any time. According to Aaron Antonovsky's nursing theory KASAM, health and quality of life are about including good comprehensibility, manageability and meaningfulness in different situations, such as a cardiac arrest.

    Aim: The purpose is to describe patients' experiences of quality of life after having survived a cardiac arrest.

    Method: A literature review based on 15 scientific articles.

    Result: In summary, the results show three main findings that have been divided into three categories. These categories are: experiences of a reduced cognitive ability and its contributing influence on the quality of life, experiences of mental health and its contributing influence on the quality of life and experiences of regaining life, existential thoughts and its impact on quality of life.

    Conclusion: The literature review shows that patients who have survived a cardiac arrest experience several changes in life. Aspects such as impaired cognitive ability, mental illness and thoughts of the existential and regaining life were most pronounced by the patients. In most cases, these experiences had a negative impact on the patients' quality of life. Many of the patients felt that the aftercare was inadequate and a great need for support from health personnel was expressed

    Evaluation of the Blazor and Angular frameworks performance for web applications2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction: Blazor is a new framework and current research show that there is a lack of performance comparisons. Therefore, a need to compare and evaluate this new Blazor framework is ought to be requested to show if it can compete with one of the best and most used frameworks, Angular. It is also one of the few web developing frameworks that has moved away from using JavaScript and therefore a comparison with a framework that uses JavaScript will be very interesting.

    Aim: The aim of this study is to make a performance comparison between two web applications using the Angular and Blazor frameworks. I will evaluate the performance and present the results to see if Blazor can compete with Angular as a modern web development framework. More specifically, the study aims to answer the following research question:

    Based on a performance evaluation would it be favorable for a developer or company to consider usingthe Blazor framework over the Angular framework when developing web applications?

    Method: I started by doing a literature review of the field I wanted to research. I used du.se library search engine, which had access to the DiVa portal, Google scholar, Summon and Libris etc. The literature was found using the keywords “Blazor”, “Angular”, “Web application”, “Framework”, “Comparison” and “Evaluation”. Thereafter, two web applications were developed for the purpose of performance evaluation of the two frameworks. An evaluation tool was used to create the report based on the measurement criterions: “First Contentful Paint”, “Time to Interactive”, “Speed Index”, “Total Blocking Time”, “Largest Contentful Paint” and “Cumulative Layout Shift”. When evaluating I summed up which framework that was more favorable in each category and displayed it in tables and graphs.

    Results: I found that the Angular framework was more favourable in 4 out of the 6 criterions. Even though Angular performed better overall it showed some very unstable performance results during the twenty tests. Blazor displayed a stable performance throughout all twenty tests in all categories and was very fast and responsive once the initial load of the client was done.

    Conclusions: Based on the results Angular was the more favourable framework during my tests, due to overall performance. But the Angular framework showed too many inconsistencies during the tests to call it superior, meanwhile Blazor performed very stable results. This indicates that the Blazor framework can possibly compete with the Angular framework as a modern web development framework. Thus, my conclusion is that it would be favourable for developers and companies to consider using the Blazor framework for new projects, especially if they have previous experience with the C# language or are new to web developement.

    Bildupplösning inom digitaltryck: - Var går gränsen för en fullgod bildkvalitet?2007Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Examensarbetet har gjorts utifrån Arkitektkopia AB:s vägnar för att undersöka gränsvärden för bildupplösning inom digi-taltryck med bibehållen bildkvalitet. Detta för att om möjligt höja produktionshastigheten då en lägre bildupplösning ger en mindre filstorlek som går fortare att cmykseparera i RIP:en. Dessutom behövde Arkitektkopia AB en korrigering och uppdatering av sin dåvarande tabell för kundrekommendationer beträffande bildupplösning för olika format och betrakt-ningsavstånd. En visuell undersökning med Arkitektkopias kunder och privatpersoner har gjorts för att kunna fastställa riktvärden för bildupplösning och utröna toleransen för en godtagbar bildkvalitet. Resultaten utifrån kundundersökningen har legat till grund för den nya tabellen med kundrekommendationer som examensarbetet resulterat i. Undersökningen omfattade tre provgrupper i formaten A4, 70x100cm och 70x100cm (motsv. 135x180cm) med betrakt-ningsavstånden 30cm, 2m och 5m. Dessutom innefattade de tre provgrupperna två olika typer av bildmotiv. Endast färg-bilder ingick i undersökningen.Resultaten utifrån undersökningen visar på att bildupplösningen kan sänkas avsevärt jämfört med tidigare kundrekommen-dationer. Störst variationer återfanns för formatet A4 med ett betraktningsavstånd på 30cm (läsavstånd). Där var toleransen för en godtagbar bildkvalitet något högre för privatpersonerna än för kundgruppen.

    A shattered sacred story: the rise and fall of the Bride of Christ within the charismatic congregation Knutby Filadelfia, Sweden2017Conference paper (Refereed)
    Abstract [en]

    Knutby Filadelfia is a charismatic Christian congregation of approximately 90 members located in Sweden. The congregation is known particularly for what has been called “The Knutby Drama” taking place in January 2004 when a pastor persuaded a young female member to shoot two members of the congregation, one of whom died. The perpetrator of the crime was under the impression that she acted according to God’s will, expressed in text messages received on her mobile phone. The murdered member’s sister, Pastor Åsa M Waldau, was dubbed “the Bride of Christ” by the media after rumours stating that she has claimed to be the New Jerusalem, and married to Jesus, which later proved correct. Waldau has had a unique position as the group´s charismatic leader since the early 1990s. The mystique surrounding Waldau’s person and a theology based on her in the role as the Bride of Christ in a semi-erotic narrative including a wedding and prophesies in the form of love letters from Jesus (called Dojadid by Waldau) has been sternly denied by leaders and members of the congregation since 2004. However, rapid changes has taken place within the group. Waldau was unexpectedly banned from the congregation in November 2016, and along with her, the charismatic pop icon-like pastor Urban Fält was thrown out of the congregation. Following these drastic measurements, the congregation publicly denounced both leaders and the Christ of Bride-theology, stating publicly that they had been the victims of psychological abuse by manipulative charismatic leaders.

    This paper presents the undercurrents in the sacred story of the Bride of Christ: how it was invented, post 2004 repressed but secretly sustained in practice, and finally by what means it was finally shattered and rejected by the congregation in 2016. It relates these developments to similar events in other new religions and discusses the possibilities of the congregation to survive and maintain its membership beyond the crisis.
