    Förmågan att förstå: kommunikation och bild hos personer med autism2006Independent thesis Advanced level (professional degree)Student thesis
    Abstract [sv]

    Syftet är att undersöka hur personer med autism med hjälp av bilder kan få förmågan att förstå samspelet i kommunikation. Våra frågeställningar är: 1. Hur tolkar och översätter omgivningen kommunikationen hos personer med autism? 2. Hur påverkar bilden förståelsen/översättningen i samspelet i kommunikationen hos personer med autism. Vi valde att göra en kvalitativ studie med intervjuer för att få med olika erfarenheter från några som är verksamma inom området. Vi har använt oss av privat litteratur, lånade böcker och kurslitteratur inom pedagogik samt information som vi hittat på Internet. Intervjuerna presenterar vi i en resultatdiskussion med kopplingar till den teoretiska kunskapen som finns i bakgrunden. Vi har valt att presentera utifrån de sammanfattningar som finns i resultatdiskussionen. Undersökningen visar hur kommunikationen sker och att bildanvändning kan underlätta kommunikationen hos personer med autism. Situationer och förutsättningar ser olika ut för varje individ med ändå finns områden som berör de flesta. Den kommunikation de har är oftast väldigt otydlig och mycket kraft går åt hos dem som finns i omgivningen till att tyda signalerna. Möjligheten att medvetet förmedla och uttrycka sina känslor och behov, t.ex. att vara hungrig och trött, kan uttryckas på ett annorlunda sätt bl.a. genom att banka och slå. Visuellt tydliggörande ger trygghet om vad som ska hända och på så vis kan många problem minskas. Bilden är ett betydande hjälpmedel för att kunna ha förmågan att förstå kommunikation och därmed visa vad man vill. Eftersom funktionshindret ställer stora krav på omgivningen gäller det att ha ett gott samarbete och tänka och planera långsiktigt.

    Planprocessen utifrån ett gentrifieringsperspektiv: En studie med gentrifiering i fokus för fyra stadsdelar i Göteborg2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Gentrification is a concept for the process of change that occurs in a neighborhood where people with high economic status move into an area that has previously been dominated by people with low socio-economic status. The process takes place step by step and affects, among other things, the economic, social, physical and cultural impression in the district. The concept itself is not well mentioned in urban planning or by politicians. Instead, they choose to use words such as integration in their work as it leaves a positive impression. The gentrification process can eventually give positive effects to a neighborhood if it generates growth and contributes to increased service in the area. However, the negative side of the gentrification process is more talked about. The negative effects are characterized by consequences for the residents in an area where the rents increase and they can no longer afford to live. The reason for the price increase and the fact that people are forced to move can be a consequence of the rebuilding and new construction run by the municipality and developers. The phenomenon occurs worldwide, but due to the extensive degree of development within the City of Gothenburg, the study will be based on the municipality. The purpose of this study is to investigate how the City of Gothenburg relate to the concept of gentrification and to what extent they work with its sanctions when they add new detailed plans for an area. The study is also meant to investigate the municipality's position on the concept as well as whether it is conscious or unconscious decisions that make, which in turn can lead to the re-enactment of the detailed planning area. In order to delimit the study, four areas were chosen in Gothenburg with similar conditions where a new detailed plan has gained legal force and exploitation is either started or completed. A qualitative method was used for reading material and interviews were held with the municipality and an developer to gain insight into the thinking about the design of the detailed plans and the exploitation. After completing the study, we have found that gentrification is a loaded concept, which means that politicians and urban planners also do not want to know it. In connection with the interviews carried out for the study, there was a lack of knowledge about the concept's existence, but a strong belief that their particular project would generate a positive gentrification effect for the area they project. Some interviewees also reported for some type of conscious gentrification when they felt that an increased population and variety of population groups could contribute to something positive despite the possible risk of gentrification in the exploited area.

    Democracy Spinning backwards?: A study of agency advocacy in Sweden2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this thesis is to assess whether agency advocacy in newspapers debate articles has increased since the 1970’s and what forms agency advocacy take. This is done by investigating if the number or share of debate articles written by agencies increased from the 1970’s to the 2000’s, what types of communication approaches and subjects that are used over the years. The theoretical approach is based on research about new public management (NPM) and mediatisation through a normative institutionalist perspective. It is mainly a quantitative study where we collect debate articles from four different decades and code the content according to three ideal types: information, agency advocacy by promoting issue and agency advocacy by legitimating agency.  The thesis finds that the share and to some extent the number of debate articles has increased over the years, which supports the NPM theory and in part mediatisation theory. All ideal types are present; agency advocacy exists in all analysed debate articles while information is highly absent.  There is little change over the years which make it difficult to assess which theory that is supported.

    Immigration & fastighetspriser2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to investigate whether the immigration to Sweden affects the Swedish real estate prices, and if so, how and to what extent. The study relates to property prices of houses in Sweden during the years 1993 – 2012. A subsidiary purpose is to investigate which group of immigrants that has the most effect on real estate prices, the returning Swedish-born or the foreign-born. The study is based on several multiple regressions including variables retrieved from the DiPasquale and Wheaton-model. The variable to be explained in the analyses is the property price and the explaining variables are interest rate, disposable income, debt, unemployment, new construction, rent, gross domestic product and immigration.

    Similarly to previous research from Switzerland, Spain, Canada, USA and New Zealand, the study concludes that there is a positive relationship between immigration and property prices. The Swedish results, however, demonstrates a stronger connection than the other countries in the short run. Regarding the subsidiary purpose regarding the influence of different groups of immigrants, the study shows that it, in the short run, is the returning Swedes that to a greater extent affect property prices

    Överklagade lantmäteriförrättningar: I Västra Götalands och Hallands län mellan år 2012 och 20172018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The study investigates and maps the extent to which decisions taken by the Cadastral authorities have been appealed in Västra Götaland County and Halland County between the years 2012 and 2017, where the years 2013 and 2016 were chosen to be studied at a deeper level. Furthermore, the study investigates differences between KLM and SLM regarding working methods and the proportion of appealed cadastral procedures. The study was conducted by reviewing 321 rulings from the Land and Environment Court, which is all the rulings regarding appealed cadastral procedures in Västra Götaland County and Halland County during the years 2013 and 2016. All 321 rulings were categorized as following; the cadastral measure being appealed, appellant, municipality, the reason for the appeal and the outcome in the Land and Environment Court and appeal to the Land and Environment Court of Appeal. In addition, interviews have been conducted with a judge and a Technical Judge from the Land and Environment Court. Interviews were also made with five current and former surveyors with experience from KLM, SLM or both. The interviews were conducted primarily to investigate differences between working methods at KLM and SLM and to investigate whether this may have any connection with the proportion of appealed cadastral procedures. The result shows that the proportion of appeals has been on average 5 % in Västra Götaland County and 4 % in Halland County between the years 2012 and 2017. The most common cadastral measure being appealed has been property reallotments and facility procedures. Furthermore, cadastral procedure costs has been the most common cause of appeal. In almost 50 % of all the reviewed rulings, the Land and Environment Court chose to establish the decisions made by the Cadastral authorities. In approximately 25 % of the cases, the court chose to change the decisions made by the Cadastral authorities. The result also showed a difference regarding the proportion of appeals between municipalities with KLM (3 %) and municipalities without (5 %). If the statistics are related to the different working methods at SLM and KLM cannot be said with certainty. From the interviews, however, it was found that many had the opinion that personal contact with the interested party and local knowledge is two important factors in order to make a good cadastral procedure. These are things that appear to be more common at KLM.

    Sjuksköterskans erfarenheter av att möta patienter med självskadebeteende: en litteraturöversikt2015Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Self harm has increased among adolescents during the last years. Studies reveal nurses' attitudes as an issue. The need to investigate nurses' experience of patients who self-harm is very important to see what is missing. Relation between nurses and patients is a vital part of caring and studies show that very little research is done in this area.

    Aim: The aim of this study is to overlook nurses' experience when they meet a patient that is self- harming.

    Metod: A literature study with a mixed approach. Articles where chosen, read, reviewed and analysed to find similarities and differences in their result.

    Results: The result came out with three main categories and seven sub categories. The first category is Difficult to understand self-injury which has two sub categories; Difficult to understand the behaviour and Difficult to understand the reason. The second category is Self- injury evokes emotions and has three sub categories; Anger, concern and anxiety, Empathy and conflicting emotions and Creates conflicts. The third category is The environmental impact on nursing care which has two sub categories; The meaning of time and Environmental influences and care.

    Conclusion: The results show that nurses felt that they needed further education about self- harm, that many of them were negative or insecure while meeting patients and did not know what to say in fear of making the behaviour worse. Many nurses also considered it hard to understand self-harm and why someone would like to harm themselves.

    Barns lek under utevistelsen på förskolan: En observationsstudie2018Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Att barn leker vet ju alla, men VAD leker de egentligen? Hur påverkas barnen av varandra, lärarna, miljön och vad har de för möjligheter? Lek är ett ord som står för så många möjligheter och lärtillfällen, så som den sociala kompetensen, samspel, fantasin, lekregler och tidigare erfarenheter. Vi har ett gemensamt intresse för utomhuspedagogiken och därför valde vi att göra en studie på barnens lek under utevistelsen. Med vår studie hoppas vi kunna uppmärksamma och belysa en del av barnens lek.

    Syfte och frågeställningar: Syftet med vår studie är att undersöka barnens lek under utevistelsen och hur den påverkas av yttre faktorer. Våra frågeställningar utgår ifrån utevistelsen på en förskola: - Vad leker barn?- Vad erbjuds barnen för valmöjligheter och material?- Hur påverkar lärarna leken?

    Metod: Vår studie är grundad i kvalitativ metod. Vi gjorde observationer under utevistelsen på en förskola vid sex tillfällen. Vi valde att vara direktobservatörer, vi var i verksamheten men deltog inte. Vid observationstillfällena antecknade vi allt vi såg och hörde. Av det empiriska materialet analyserades det fram olika mönster och tillfälligheter. De analyserade materialet bearbetade vi och delade upp i teman.

    Resultat: I resultatet redovisas sekvenser ur det empiriska materialet och det framgår tydligt att leken är det centrala under utevistelsen. Många barn visar att de har lekkompetens och kan lekregler. Det är lekregler som grundar sig i det sociala samspelet, detta innebär till exempel att de skyddar och begränsar sin lek för att hålla den aktiv. En lek behöver en ledare som styr och som får leken att fortgå och ledaren väljs i tystnad. Att vara en bra ledare kräver att man kan samspela, kan förnya leken om det krävs och få med sig lekkamrater. I resultatet syns barnens kompetens i och kunskap om att konstruera och skapa, både själva och med varandra. Att den kan leka själva visar på att barnen känner trygghet till förskolan. Många av rollekarna de lekte var klassiska och typiskt könsstereotypa såsom prinsessa, brandman, polis och tjuv och mamma-pappa-barn.

    Motivationsaspekter inom olika branscher: Hur stor påverkan har egentligen motivationen på prestationen inom en organisation?2016Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [sv]

    I denna uppsats inom Metod & Uppsats i företagsekonomi studerar vi hur motivationen kan ha en påverkan på prestationen, inom olika branscher. Det finns flera motivationsfaktorer som kan utövas och en av dem är Herzbergs motivationsteori som vi tar upp i bakgrunden och teoriavsnittet. Studiens syfte är att undersöka den påverkan som motivationen har inom en organisation och arbetet där i. För att kunna besvara vårt syfte kommer vi hämta information från både vetenskapliga artiklar, intervjuer samt övrig litteratur som är relevant för denna studie.

    Vidare beskrivs olika motivationsfaktorer som kan utövas inom organisationer. Mål och motivationsfaktorer har en koppling till varandra då man behöver mål för att kunna få viss typ av motivation. Motivation och värden tas även upp för att kunna skapa en förståelse för hur det kan se ut inom organisationer och hur vissa använder dessa aspekter i hopp om att kunna öka motivationen. Huvudfokus för denna uppsats är alltså motivation.

    Avgränsningar inom denna rapport sker via utvalda branscher vi valt ut där både ledare och anställda arbetar. Detta för att kunna smalna av rapportens område och endast fokusera på en viss kategori av organisationer. Utifrån detta vill vi besvara vårt syfte.

    Metodvalet för denna uppsats föll på en kvalitativ metod. Vi anser att denna metod är lämplig för denna typ av studie då vi genomför intervjuer samt samlar in data från vetenskapliga artiklar och övriga källor. Dessutom använder vi oss utav en intervjuguide.

    I empirin presenteras de svar vi fått från de respondenter vi intervjuat för denna studie. Vi har intervjuat både ledare och anställda för att kunna få en spridning inom organisation och motivation. Detta tror vi även ökar tillförlitligheten för denna studie.

    Analysavsnittet innehåller sammanställning av den information vi samlat in till teoriavsnittet för att sedan kunna koppla samman detta med intervjusvaren vi fått fram via intervjuer med samtliga respondenter. Detta för att kunna jämföra hur det faktiskt ser ut inom organisationer inom motivation och hur respondenterna faktiskt upplever motivationen som utövas.

    Slutsatsen innehåller den slutsats vi kommit fram till. Vi anser att vi kan besvara vårt syfte med denna studie. Vi kan dra slutsatser kring hur motivation utövas inom de olika organisationer som vi har studerat.

    There´s no sound in space: En studie om ljuddesign för fiktiva objekt inom Science Fiction2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis work examines how a sound can affect the experience of an object with the focus set on sound design for an object which lacks a real world reference. The study's purpose was to research the experience of an object in relation to the sounds level of realism. We collected data through web based surveys to see how an object could be perceived differently by just altering the level of realism in the sound. The survey then gets backed up by an analysis of two movies where the related phenomenon where present. Our results leads to a discussion where possible correlations between sound and it’s level of realism are revealed which then could become a foundation for future studies.

    Review of Weldability of Precipitation Hardening Ni- and Fe-Ni-Based Superalloys2018In: Proceedings of the 9th International Symposium on Superalloy 718 & Derivatives: Energy, Aerospace, and Industrial Applications / [ed] Ott, E., Liu, X., Andersson, J., Bi, Z., Bockenstedt, K., Dempster, I., Groh, J., Heck, K., Jablonski, P., Kaplan, M., Nagahama, D. and Sudbrack, C., Springer, 2018, p. 899-916Conference paper (Refereed)
    Abstract [en]

    Fabrication and welding of structural components for the hot section of aero-engines continues to be of high importance to the manufacturing industry of aero-engines. This paper discusses and reviews the literature on hot cracking and strain age cracking, cracking phenomena that can occur during welding or subsequent heat treatment of precipitation hardened Ni- and Fe-Ni-based superalloys. The influence of chemical composition in terms of i.e. hardening elements and impurities, microstructure of base material and weld zone, together with welding processes and corresponding parameters and heat input are discussed and related to the cracking susceptibility of different nickel based superalloys.

    Abstract [en]

    Information about the book:

    This is the fourth volume in the well-established series of compendiums devoted to the subject of weld hot cracking. It contains the papers presented at the 4th International Cracking Workshop held in Berlin in April 2014. In the context of this workshop, the term “cracking” refers to hot cracking in the classical and previous sense, but also to cold cracking, stress-corrosion cracking and elevated temp. solid-state cracking.  A variety of different cracking subjects are discussed, including test standards, crack prediction, weldability determination, crack mitigation, stress states, numerical modelling, and cracking mechanisms.  Likewise, many different alloys were investigated such as aluminum alloys, copper-aluminum dissimilar metal, austenitic stainless steel, nickel base alloys, duplex stainless steel, creep resistant steel, and high strength steel.

    Repair welding of wrought superalloys: Alloy 718, Allvac 718Plus and Waspaloy2012In: Science and Technology of Welding and Joining, ISSN 1362-1718, Vol. 17, no 1, p. 49-59Article in journal (Refereed)
    Abstract [en]

    The ability to weld repair three precipitation hardening superalloys, i.e. Alloy 718, Allvac 718Plus and Waspaloy, with gas tungsten arc welding, is compared in this study. Four different solution heat treatment conditions for each material were examined: Alloy 718 and Allvac 718Plus heat treated at 954uC–1 h, 982uC–1 h, 954uC–15 h and 1020uC–1 h and Waspaloy for 4 h at 996uC, 1010uC, 1040uC and at 1080uC. By metallography, the total number of cracks was evaluated in both the heat affected zone and the fusion zone, which made it possible to consistently rate the repair weldability of these three materials. Alloy 718 was significantly the best one, with Allvac 718Plus slightly better than Waspaloy. As expected, the solution heat treatment conditions only affected the heat affected zone cracking behaviour.

    Metallurgical Response of Electron Beam Welded Allvac® 718Plus™2011In: Hot Cracking Phenomena in Welds III / [ed] Lippold, J., Böllinghaus, T. and Cross C. E., Springer Berlin/Heidelberg, 2011, p. 415-428Conference paper (Refereed)
    Abstract [en]

    Electron beam welding of forged Allvac 718Plus superalloy has been carried out without any visible cracks in weld cross-sections. Healed cracks in the heat affected zone were, however, seen in most cross-sections with the healing as well as the cracking believed to be due to the constitutional liquation of the δ-phase. The δ-phase undergoes constitutional liquation in the Heat Affected Zone (HAZ) and consequently decreases the ductility of the material and renders cracks in the HAZ but due to the large amount of eutectic liquid produced at the same time the healing of the opened cracks takes place.

    Hot Cracking of Allvac 718Plus, Alloy 718 and Waspaloy at Varestraint Testing2008In: 4th International Symposium on Aerospace Materials and Manufacturing Processes: Advances in Processing and Repair of Aerospace Materials 2008 / [ed] M. Jahazi, M. Elboujdaini and P. Patnaik, Montreal: Canadian Institute of Mining, Metallurgy and Petroleum, 2008, p. 401-413Conference paper (Refereed)
    Abstract [en]

    Varestraint testing together with DSC and SEM-EDX analyses have been performed as means of investigating the hot cracking susceptibility of Allvac 718Plus, alloy 718 and Waspaloy. The solidification sequences in Allvac 718Plus and alloy 718 were very similar to each other starting by an initial solidification of the gamma phase, gamma/MC reaction at around 1260°C and then finally ending the sequence by gamma/Laves eutectic reaction at around 1150°C. Waspaloy had the same solidification sequence, except no Laves phase formation takes place, and solidification started at a somewhat higher temperature as compared to alloy 718 and the solidification sequence ends by a gamma/MC reaction at around 1245°C. The total amount of hot cracking in Waspaloy was shown to be much less than that in alloy 718 and in Allvac 718Plus which is believed to be related to the presence of the Laves eutectic in the latter two alloys with corresponding larger solidification ranges. Hot cracking of 718Plus is slightly less than in 718.

    Effect of Different Solution Heat Treatments on the Hot Ductility of Superalloys: Part 3 - Waspaloy2013In: Materials Science and Technology, ISSN 0267-0836, E-ISSN 1743-2847, Vol. 29, no 1, p. 43-53Article in journal (Refereed)
    Abstract [en]

    The susceptibility to heat affected zone cracking of Waspaloy has been investigated in terms of its hot ductility, measured as the reduction of area (RA). Gleeble testing with on-heating as well as on-cooling test cycles was carried out to illuminate the influence of different 4 h solution heat treatments between 996 and 1080°C. A ductility maximum of between 80 and 90%RA was found at 1050–1100°C for all conditions in the on-heating tests. Although the different heat treatment conditions showed similar macrohardness, the particle size and distribution of the γ′ and M23C6 phases differed, which significantly affected the on-heating ductility in the lower temperature test region. The ductile to brittle transition was initiated at 1100°C in the on-heating testing with indications of grain boundary liquation at the higher test temperatures. Ductility recovery, as measured in the on-cooling tests from 1240°C, was very limited with <30%RA for all conditions and test temperatures except for the 1080°C/4 h treatment, which exhibited 60%RA at 980°C.

    Effect of different solution heat treatments on hot ductility of superalloys: Part 2 – Allvac 718Plus2012In: Materials Science and Technology, ISSN 0267-0836, Vol. 28, no 6, p. 733-741Article in journal (Refereed)
    Abstract [en]

    The hot ductility of Allvac 718Plus for different solution heat treatments (954°C–15 h, 954°C–1 h, 982°C–1 h and 1050°C–3 h+954°C–1 h) has been investigated using Gleeble testing. Substantial variations in the microstructure among the heat treatments affected the Gleeble test hot ductility only to a very limited extent. Constitutional liquation of the NbC phase was found to be the main cause for the poor ductility at high testing temperatures in the on-heating cycle as well as at the lower temperatures on-cooling. Grain boundary δ phase was seen to assist the constitutional liquation of the NbC phase. Based on established evaluation criteria for Gleeble ductility testing, a ranked indicator for weldability is suggested.

    Effect of solution heat treatments on superalloys: Part 1 – alloy 7182012In: Materials Science and Technology, ISSN 0267-0836, Vol. 28, no 5, p. 609-619Article in journal (Refereed)
    Abstract [en]

    The hot ductility as measured by Gleeble testing of Alloy 718 at four different solution heat treatments (954°C/15 h, 954°C/1 h, 982°C/1 h and 1050°C/3 h+954°C/1 h) has been investigated. It is concluded that constitutional liquation of NbC assisted by δ phase takes place and deteriorates the ductility. Parameters established by analysing the ductility dependence on temperature indicate a reduced weldability of the material in the coarse grain size state (ASTM 3) while indicating an increased weldability when containing a large amount of δ phase due to a grain boundary pinning effect. The accumulation of trace elements during grain growth at the highest temperature is believed to be the cause for the observed reduced on-cooling ductility.

    A computational geometry method for centrifugal compressor impellers2016Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Modern centrifugal compressor impeller geometry often consist of curves and surfaces with a high degree of three dimensionality. This makes the geometry of the impeller difficult to model with commercial CAD-tools. Additionally, in modern optimization processes of impellers the geometry is commonly altered, this puts high demands on the method that is used for generating the geometry. In this work a new computational geometry method for centrifugal compressor impellers is compiled. The new method is designed to be flexible and to support present day optimization processes.The new method is a compilation based upon publications regarding impeller geometry and impeller optimization. It utilizes Bezier curves and B-splines to generate geometry and supports optimization by allowing control points of the constructing curves to be relocated to change the shape of the geometry. To test the new method, a standalone application was successfully developed with the aid of the SCRUM development process. With an easy to use graphical user interface the application generates and displays a 3D model of the geometry generated with the new method.

    Läsande och motiverande arbetssätt: en studie kring elevers läsintresse2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    För att undersöka på vilket sätt lärare kan stimulera elevers läsintresse valde jag att undersöka hur läsintresset ser ut i ett urval av klasser i grundskolans årkurser 4-6, och därtill försöka koppla detta intresse till lärares arbetssätt. En enkätundersökning genomfördes i fem olika klasser från årskurserna 4-6 och därtill genomfördes intervjuer med verksamma lärare i de klasser där enkätundersökningarna ägt rum. Undersökningen visar på att det finns en positiv inställning till läsning bland de elever som deltagit. Därtill framkommer att flickors upplevelse av läsintresse kan tänkas vara mindre styrt av arbetssätt då de oberoende av arbetssätt, uppvisar en jämt fördelad inställning till läsning.

    Utvärdering och förbättring gällande Volvo Aeros tillämpning av metodiken praktisk problemlösning2012Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Volvo Aero develops, designs, manufactures and performs maintenance of engine and related components for civil and military aircrafts. The vision is to deliver world-leading transport solutions through continuous improvement and long term business deployment, which for the daily work means systematic problem solving through the methodology practical problem solving, whose origin is Toyota.

    The purpose of this thesis was to examine whether Volvo Aero’s approach of practical problem solving was simple, systematic and guided, which from Toyota’s point of view creates sound conditions for effective problem solving.

    Initially, Toyota’s attitude and behaviour towards problem solving was described from the point of view of The Toyota Way. Thereafter, a literature study on practical problem solving was completed. Furthermore, a pilot study was carried out where Volvo Aero’s approach to practical problem solving was applied to an organisational problem. The pilot study was evaluated and areas for improvements were identified where the methodology was difficult, indistinct and inadequate guided. Finally, improvements were proposed regarding Volvo Aero’s approach to practical problem solving, which was scientifically anchored to Toyota.

    • Defining and analysing the symptoms brings understanding for the causes of the problem
    • Quantifying the present condition and the expected illustrates the magnitude of the problem
    • Appears the root cause to be clear is probably the countermeasure obvious
    • A considerable approach using Plan-Do-Check-Act (PDCA) provides an effective and strong tool for continuous improvement

    The improvements were proposed with purpose to simplify Volvo Aero’s methodology and to support and guide the user, which creates sound conditions for effective problem solving and provides opportunities for daily use that foster continuous improvement.

    Kamratbedömning för alla?: En diskursanalytisk studie om kamratbedömning i årskurs 4–62018Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: I läroplanen Lgr 11 framkommer det att elever i grundskolan ska agera kamratbedömare genom att ge och ta emot respons. I fråga om vem denna aktivitet gynnar, och på vilket sätt den för-väntas vara en del av undervisningen i svensk skola, är detta inte helt klart. En anledning att låta eleverna ägna sig åt kamratbedömning kan dock ses inom arbetet med formativ bedömning, där eleverna kan utgöra läranderesurser för varandra, då det kommer till bedömning för lärande.

    Syfte: Vår studie har syftat till att undersöka hur lärare beskriver sitt arbete med kamratbedömning i årskurserna 4–6. Anledningen till detta var att vi ville se hur lärare talar om sin syn på kamrat-bedömning och därigenom se till hur de beskriver olika arbetssätt, vilka förutsättningar de anser ligger till grund och vem det är som gynnas av kamratbedömning.

    Metod: Studien har varit av kvalitativ art och vi har i vårt framtagande av empiri använt oss av halv-strukturerade intervjuer, som vi genomförde med sex informanter som är verksamma lärare inom den åldersgrupp som vi har haft för avsikt att undersöka. I analysförfarandet har vi använt oss av diskursanalys för att belysa de diskurser som brukas av studiens informanter.

    Resultat: I vårt resultat fann vi att i samband med kamratbedömning fanns det olika sätt att tala om elever, arbetssätt och förutsättningar. Dessa sätt att tala presenterar vi som diskurserna: eleven som högpresterande, eleven som lågpresterande, det positiva arbetssättet, det granskande arbetssät-tet, stöd som förutsättning och klassrumsklimatet som förutsättning.

    Framtagning av standardiserat arbetssätt och kitlådor för montering av lågtrycksturbiner2019Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This bachelor thesis has been executed at GKN Aerospace at the manufacturing department Low Pressure Turbine (LPT), also known as LPT. The thesis presents the creation of standardized working methods for the assembly of the LPTs, that are manufactured for the aircraft engines Leap 1B and Leap A/C. The standardized work has been compiled in Job Training Documents, also known as JTD. A kit box for the material that will be assembled has been designed for each model. Due to a nonexistent standard it has led to assembly failures and quality defects in the production. The existing assembly box has been inadequate for the operators and the controllers that pack the boxes which has led to longer assembly time. The purpose of this project has been to assure the quality of the work through creating standardized work instructions. The design of the kit box has been executed in order to organize the details of the assembly in a certain structure to facilitate for the operators and controllers. An operation description with course of action was provided and used as a basis for the design of the JTDs in order not to risk deviating from the existing method. Interviews and observations of operators and controllers have also been used for the JTDs and the design of the kit boxes. Kit boxes was reused from another department and assortment boxes was sorted and structured inside in two different sizes. These were coded with different colors, marked and fitted to the size and quantity of the material so that every piece that is being assembled has its own place. The JTDs and the kit boxes was made in two versions to adapt to the assembly of both Leap 1B and Leap A/C. The boxes were tested in the production and the JTDs was reviewed of the operators before signature was made. All of the operators were not interviewed and observed as planned because of the unplanned stops in the production. The shape of the kit box was limited because the existing boxes were reused. From the results that has been developed the goals for this thesis including creating standardized work instructions and design of a kit box to organize all the pieces has been achieved.

    Patient-reported genitourinary dysfunction after laparoscopic and open rectal cancer surgery in a randomized trial (COLOR II).2014In: British Journal of Surgery, ISSN 0007-1323, E-ISSN 1365-2168, Vol. 101, no 10, p. 1272-1279Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: This article reports on patient-reported sexual dysfunction and micturition symptoms following a randomized trial of laparoscopic and open surgery for rectal cancer.

    METHODS: Patients in the COLOR II randomized trial, comparing laparoscopic and open surgery for rectal cancer, completed the European Organization for Research and Treatment of Cancer (EORTC) QLQ-CR38 questionnaire before surgery, and after 4 weeks, 6, 12 and 24 months. Adjusted mean differences on a 100-point scale were calculated using changes from baseline value at the various time points in the domains of sexual functioning, sexual enjoyment, male and female sexual problems, and micturition symptoms.

    RESULTS: Of 617 randomized patients, 385 completed this phase of the trial. Their mean age was 67·1 years. Surgery caused an anticipated reduction in genitourinary function after 4 weeks, with no significant differences between laparoscopic and open approaches. An improvement in sexual dysfunction was seen in the first year, but some male sexual problems persisted. Before operation 64·5 per cent of men in the laparoscopic group and 55·6 per cent in the open group reported some degree of erectile dysfunction. This increased to 81·1 and 80·5 per cent respectively 4 weeks after surgery, and 76·3 versus 75·5 per cent at 12 months, with no significant differences between groups. Micturition symptoms were less affected than sexual function and gradually improved to preoperative levels by 6 months. Adjusting for confounders, including radiotherapy, did not change these results.

    CONCLUSION: Sexual dysfunction is common in patients with rectal cancer, and treatment (including surgery) increases the proportion of patients affected. A laparoscopic approach does not change this.

    Uppstartsguide för Febdok2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Detta examensarbete har utförts på ÅF Industry i Trollhättan. Syftet med examensarbetet är att arbeta fram rutiner och ett standardiserat arbetssätt i Febdok. Detta för att underlätta och spara tid vid användning av Febdok. Inledningsvis påbörjades framtagning av relevant teori kring den definierade problembeskrivningen tillsammans med handläggaren på ÅF. Parallellt genomfördes övningsexempel i Febdok för att gruppen skulle få en insyn i hur funktionerna fungerar. Rapportens teoridel behandlar de mest problematiska- och tidskrävande funktionerna i Febdok så som UPS:er, kortslutningsströmmar och selektivitet. Det för att ge en förståelse om bakgrunden till funktionerna. Ett beräkningsexempel på ett fiktivt nät gjordes för att kunna verifiera en överslagsräkning som används på ÅF för att beräkna ett ungefärligt värde på minsta felström. Denna minsta felström erhålls vid enfasig jordslutning och definierar utlösningsvilkoret. Maximal felström delat på tre har ansetts ge ett någorlunda korrekt värde på minsta felström. Beräkningar på maximal- och minimal felström vid olika kablage jämfördes och visade att överslagsräkningen inte är att rekommendera på grund av att minsta felström ibland bli lägre. Istället bör en faktor av minst fyra användas vid överslagsräkningen för minsta felström. I avsnitt 3 i rapporten beskrivs initiala inställningar och funktioner i Febdok med föregående teori som bakgrund. Implementering av UPS:er i Febdok visade sig kräva mer datainmatning än vad som normalt går att få tag på från tillverkare. Genomsläppt energi är data som visade sig svår att få tag ifrån olika tillverkare. Vid närmare tester av programmet och dess funktioner visade det sig att genomsläppt energi inte behövs definieras i UPS-funktionen för att arbeta med selektivitet och kortslutningsströmmar längre ut i anläggningen.

    Resultatet av observationerna i Febdok och teorin visade att tumregeln som används på ÅF inte är att föredra och säkringar i en anläggning försedd med UPS bör dimensioneras efter batteridrift. Informationen och kunskaperna som samlades under arbetets gång samanställdes i en uppstartsguide för Febdok.

    Work-family conflict och dess samverkan med individens upplevelse av sin hälsa: en studie på svenska tjänstemän2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Arbetsmiljöverkets AFS 2015:4 is focused on the problems that can occur when employees experience that their work-life has a negative impact on their familylife. In the world of psychology this experience is called "work-family conflict", and the conflict consists of two dimensions; work interference with family, and family interference with work. This study had two major study subjects; possible antecedents and their correlation with work-family conflict, and if the experience of work-family conflict has an association with how persons experience their own health. The respondents consisted of 302 Swedish white-collar workers (53% women) who worked for a logistics business. The study had a quantitative method where the respondents answered a survey, which was made from several well used instruments; Copenhagen psychosocial questionnaire version II (COPSOQ II), a modernized and translated version of Netemayer et al.'s (1996) survey, and Quality marriage index (QMI). A multiple linear regressions analyzer showed that the six antecedents explained 20% of the variance in the dimension Privatliv-Arbetsliv (family interference with work), and 21% of the variance in the dimension Arbetsliv-Privatliv (work interference with family). The study found a strong correlation between the variable Allmän hälsa (eng: General health) and Arbetsliv-Privatliv (r = -.62). This indicates that there is a negative association between Swedish white collar workers self experienced general health and the grade of Arbetsliv-Privatliv conflict they experience.

    Abstract [en]

    In community planning, there are many regulations that can be made to control land use and a detail development plan is an instrument that Sweden's municipalities have access to in order to do so. In a detail development plan, the municipality may specify properties that will apply in an area, such as the protection of trees, whish this study is about. To protect trees a plan regulation is required in the plan indicating what is applicable. In the Planning and Building Act 9 chap. 12 § it is stated that the municipality in a detail development plan may decide that a land permit is required for felling trees and for afforestation. An application for a permit to felling trees and / or afforestation shall be sent to the municipality, which will examine whether the application is to be granted or refused. Entering a land permit for felling trees in the detail development plan protects trees that may otherwise be cut down without the municipality's knowledge.

    The survey aims at examining the extent to which the municipalities of Sweden use the opportunity to decide on land permits in a detail development plan. Furthermore, the municipality's motive for the protection of trees is investigated and if it is done otherwise than with the plan regulation, and whether there has been any change in how the municipalities regulate trees in 2017 compared to 1990, when the detail development plan had recently been introduced. This has been done with both qualitative and quantitative methods to get a versatile and complete study.

    The results show that the municipalities used the plan regulation for land permit for felling trees in 60 of the detail development plans in 2017. To ensure protection of trees municipalities use other methods than land permit, for example a Plan regulation to protect trees. The motives given by the municipalities to protect trees vary widely and there are ecological, social and aesthetic reasons. In the comparison of detail development plans from 2017 and 1990, differences have been observed. More plans in 2017 with land permit for felling trees have been observed as well as more and more varied motivations. Plan regulation about afforestation has been found only once in a total of 1 353 detail development plans.

    Abstract [en]

    Since Twitch started its livestreaming site in 2011 live streaming have grown incredibly fast. In 2014 Twitch had 100 million unique viewers monthly. The streams on Twitch range from esports players to people streaming for fun. Today there are streamers that are not working but instead create a living based on streaming and micro donations from its viewers. We are curious and want to explore how a streamer can live just by playing computer games. They accumulate an audience who will return as soon streamer begins streaming. In addition to advertising on their page to get streamers into micro donations through their viewers. These micro donations account for a large portion of their income.

    We focus on those watching rather than those who stream. How is it that someone would be willing to donate money to a streamer? We then decided to do a survey on motivation and microdonations Twitch viewers will answer. The questions is focused on what kind of genre, user prefer to watch and and what motivates them to donate.

    In our study, it was only 36.5% who spent less than 4 hours per week on Twitch, the rest of the responses were from people who spent over 4 hours. According to the responses of our survey people were not affected by others when it came to the choice of stream to watch. Many people choose the stream due to the streamer being entertaining or playing the same game as the streamer. Even if the people who answered our survey spent alot of time on Twitch only a part of them choose to donate 43% of them have neither donated or subscribed to a stream before. Only 5.5% donates much (over $ 10) and often. According to the answers only 56.1% have donated or subscribed to a stream before. We must take into account that 75.6% are young people under 24 years old and may not have an income, hence it is difficult to donate despite the fact that they want. Although many are donating very small sums, there are people who donate incredibly large sums which a streamer can almost fall into a state of shock.

    There was a number of different factors that motivated people to donate their money to streamers. The three most prominent factors were “Entertaining streamer” a streamer who engages the audience and makes them laugh, “I play the same game” the viewers recognize the game and play it during their own time and “I want to learn something” the viewers want to improve their own skills and learn something new. More than half the people who responded would be willing to spend atleast 10$ a month on Twitch related material. Most of the people who answered were men and around 1525 years. Benefits i.e getting something in return for a donation had a much lower impact towards motivating people than expected.

    "Det handlar inte bara om att åka skridskor...": En kvalitativ studie om undervisningen i friluftsliv inom fritidshem och ämnet idrott och hälsa2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Studiens övergripande syfte var att undersöka hur undervisning i friluftsliv utövas i ämnet idrott och hälsa och inom fritidshem samt vilka skillnader och likheter som finns. Syftet var även att se om ett kollegialt samarbete mellan idrottslärare och fritidslärare finns idag och vad som påverkar lärarnas sätt att bedriva friluftsliv i undervisningen. Frågeställningarna vi utgick ifrån vid undersökningen av vårt syfte var: Hur definierar fritidslärarna och fritidslärarna delen friluftsliv? Finns det något kollegialt samarbete mellan fritislärarna och idrottslärarna kring undervisningen i friluftsliv? Vad påverkar lärarnas sätt att bedriva undervisningen i friluftsliv?   Den metod som användes för att besvara studiens frågeställningar var en kvalitativ intervjustudie och vårt empiriska material bestod av individuella intervjuer i två olika kommuner. Vi genomförde sammanlagt sex semistrukturerade intervjuer med tre utbildade idrottslärare och tre utbildade fritidslärare.  Studiens samanställda resultat visar att synen på undervisningen i friluftsliv samt sättet att bedriva det i praktiken skiljer sig mellan de båda yrkeskategorierna och genom resultatet kunde vi även finna påverkansfaktorerna för det. Utifrån resultatet framgick att det inte pågår ett kollegialt samarbete mellan fritidslärare och idrottslärare i dag, men att det är önskvärt. Resultatet visade även att läroplanen är en grundläggande orsak till att det skapas begränsningar kring undervisningen i friluftsliv.

    Möjligheter och begränsningar för att uppleva hälsa hos barn med övervikt eller fetma: - En litteraturöversikt2015Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background:

    More people die from overweight or obesity today than people who die from underweight. It is one of the largest risks for the human health today. Overweight and obesity may lead to diseases such as depression, diabetes type 2, cancer, isolation and cardiovascular diseases. Overweight and obesity among children have increased over the past three decades, and follows often the child from childhood to adulthood. Aim: The aim of this study was to discover the limitations and possibilities to experience health among children with overweight or obesity. Method: A literature review based on ten articles was chosen as method for this study. Through the analysis of the authors, five themes were discovered and created. They included information about the well-being of children, age 4 to 17 years, with overweight or obesity. Results: The themes were; Being teased and exposed to bullying, Expression of thoughts and feelings, Importance of community, Children's views of themselves and The belief in and the ability to live a healthy life. Conclusion: Children with overweight or obesity, had difficulties to experience health. Higher rates of bullying, alienation, anxiety, poor self-image and fear of consequences were found in children with overweight or obesity.

    "Skitiga ungar är lyckliga barn": Pedagogers perspektiv på den dagliga utomhusvistelsen i förskolan2014Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund

    Den dagliga utomhusvistelsen på gården är en stor del av barns vardag på förskolan. En rådande uppfattning inom förskolans verksamhet är att "det finns inget dåligt väder, bara dåliga kläder" och

    alla barn ska vistas utomhus minst en gång om dagen, varje dag. En stor del av den forskning som finns tillgänglig inom området för utomhusvistelse fokuserar på det som kallas "utomhuspedagogik" och behandlar inte den vardagliga utomhusvistelsen i samma utsträckning.

    Syfte

    Syftet är att undersöka hur pedagoger i förskolan resonerar kring den vardagliga utomhusvistelsen på förskolans gård och hur de motiverar denna och dess betydelse samt vilken möjlighet barnen har till delaktighet.

    Metod

    Vi har genomfört tre fokusgruppintervjuer med sex pedagoger, både förskollärare och barnskötare. Intervjuerna har därefter analyserats med inspiration från den fenomenologiska inriktningen hermeneutik. Resultatet presenteras utifrån tre temaområden

    "Det är bra att vara utomhus", "Utomhusvistelse på gården" och "Delaktighet".

    Resultat

    Resultatet visar att utomhusvistelsen är en rutin på förskolan som sällan ifrågasätts. Samtliga pedagoger i våra intervjuer var positiva till utomhusvistelsen och dess möjligheter för barnens välmående och utveckling. Samtidigt som pedagogernas resonemang överlag är snarlika, så visar resultatet att det finns flera olika sätt att förhålla sig till barns vistelse utomhus

    Tiotalsövergångar i subtraktion: sambandet mellan lärarens undervisning och eleversval av strategi2014Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Matematik diskuteras ofta som ett problematiskt område och internationella undersökningar visar att de svenska matematikkunskaperna sjunker. En studie av Johansson (2011) visar att subtraktion med tiotalsövergång är ett svårt område för många elever. Tidigare forskning belyser vikten av didaktiska överväganden hos lärarna vid introduktion av subtraktionsberäkningar, forskningen beskriver också vilka förkunskaper som är viktiga att elever får för att underlätta området. För att få en bättre insikt i vad det är som gör området svårt ville vi undersöka hur verksamma lärare brukar introducera subtraktion och hur det påverkar eleverna.

    Syfte:

    Vårt syfte är att undersöka hur sambandet mellan elevens val av metod och undervisningen i subtraktion där tiotalsövergångar krävs hänger samman.

    Metod:

    Studiens datainsamling skedde genom kvalitativa intervjuer med både lärare och elever för att få reda på hur de ser på området med tiotalsgångar inom subtraktionsberäkning. Eleverna fick beräkna matematikuppgifter och berätta hur de tänkte för att ge en tydlig bild av vilka strategier de kunde. Alla intervjuerna sammanfattades för att de sedan skulle kunna analyseras utifrån vanligt förekommande lösningsstrategier och variationsteorin.

    Resultat:

    Resultatet visar att den vanligaste förekommande strategin som eleverna använde sig av var den som läraren mest gått igenom. Många elever visade förtrogenhet med fler än en strategi, det visade sig också att de i de allra flesta fall väljer samma metod som läraren föredrar som förstahandsval

    Digitala verktyg i förskolan: En studie om förskollärarnas användning av digitala verktyg2015Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Grunden för denna studie är att undersöka hur förskollärare använder sig av digitala verktyg och vilka verktyg som är mest förekommande i förskolans verksamhet. Syfte: Syftet med studien är att få fördjupad kunskap om hur arbetet med digitala verktyg ser ut i förskolans verksamhet samt vilka digitala verktyg som är mest förekommande. Frågeställningar: På vilket sätt används digitala verktyg i förskolans verksamhet? och Vilka av dessa verktyg är mest förekommande i arbetet med barn? Metod: En muntlig strukturerad intervjustudie med tolv förskollärare från fem olika förskolor som i sitt genomförande kan beskrivas som muntliga enkäter. Dessa muntliga enkäter/ intervjuer genomfördes på förskolorna. Studien presenterades och de strukturerade intervjuerna spelades in för att vi skulle kunna transkribera svaren. Intervjuerna hade karaktären av en enkät vilket innebär att vi huvudsakligen ställde frågorna utifrån ett bestämt frågeformulär utan uppföljningsfrågor. Förskolorna som deltog i studien valdes med hjälp ett bekvämlighetsurval.

    Resultat: Av studiens resultat framgår det att digitala verktyg används regelbundet i verksamheten och på varierande sätt: till dokumentation, informationssökning, ibland förekommer det att digitala verktyg används som "barnvakt", sagostunder och sångstunder. Surfplattan är verktyget som förekommer oftast i förskolans verksamhet på grund av att det är lätt ta med överallt och för att det är enkelt att skriva dokumentation via surfplattan.

    Skolbibliotek och undervisning: En studie om lärare och skolans bibliotekariers uppfattningar om skolbibliotekets roll i undervisningen2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this paper has been to study teachers´ and librarians´ perspectives of the role of the school library in education in secondary schools. The study is based upon interviews with teachers and librarians from two different schools. We are inspired by phenomenography but we use a descriptive method and the following four parts are described in our result: the use of the school library, investigative approaches, the role of the school library and its environment and the role of the librarian. The conclusions which are evident from our research suggest the library has a fundamental role in the heart of the school. The school library is a multi-functional service used to support school studies, independent work and promote and encourage the reading of fiction. Essential to making the school library function well is professional staff, inspiring new literature and sufficient space to allow such functions to operate without disturbing each other. To ensure co-operation functions optimally the two professions must work effectively together as one team, understanding each other’s roles fully.

    Handläggningstiden vid bygglov: En studie kring kravet i PBL 9:272015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    With Swedish planning and building act (PBL) of 2011 a new demand was adopted for handling time before permits and advance rule, called PBL 9:27. Following PBL 9:27 an application for permits shall be processed promptly and the applicant shall be informed of the decision within ten weeks from the moment a complete application has been submitted to the local building committee. Previously this demand had not been included into Swedish law. The purpose of this demand was to speed up the handling time and to reduce differences in handling time between municipalities. When this demand was adopted a decision was made not to connect it with any form of sanction, should the demand not be met. The argument being that a more effective handling time would be met even without sanctions. Following several notifications to the legal ombudsman one may conclude that in several cases, municipalities do not meet the demand for a handling time within ten weeks. While there are no sanctions connected to the demand municipalities, may without any risk, take as much time they fell needed for the handling of each case. Thereby one of the key purposes of PBL 9:27, that is, reduced differences in handling time between municipalities is counteracted.

    The purpose of this study is to investigate whether handling time in building permit cases are in compliance with PBL 9:27. In order to answer this question building permit cases were examined thoroughly in seven municipalities in Västra Götaland County. The study has focused cases from 2014 and cases pertaining to construction of buildings. The collected information was compiled in one data matrix for each municipality. Beside of the information compiled in the data matrix each municipality answered a questionnaire focusing workload. The purpose of the questionnaire was to relate the results from the investigation of handling time to a possible explanation, that is, the workload of employees during 2014.

    Out of 436 examined cases 44 did not meet the demand of handling tie within ten weeks, or approximately 10 % of the cases. Of these 44 cases that did not meet PLB 9:27, 32 were real estates that were located within areas regulated by detailed municipal plans and twelve were located outside of planned areas. Out of the 32 real estates located within planned areas 13 accounted for a minor deviance from the detailed municipal plan while 19 were in compliance with the detailed plan and

    regulation areas.

    The results indicate that municipalities need to speed up their handling time for building permit cases regulated by PBL 9:27. An additional result of this study is that several municipalities have flaws in relation to documentation of significant dates. Also, municipalities tend to make different assessments of when an application is considered complete. This study suggests that clearer guidelines are adopted pertaining to documentation of cases and the demands for how to assess if an application is complete.

    "En av våra viktigaste uppgifter är just värdegrundsarbete": En kvalitativ studie om fritidspedagogens upplevelse och beskrivning av värdegrundsarbete2015Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund

    Intresset av att undersöka hur fritidspedagogen upplever och beskriver värdegrundsarbetet på fritidshemmet växte under vår VFU då vi såg en tendens till att elevers respekt gentemot varandra och vuxna minskar. Eftersom värdegrunden är en stor del av fritidspedagogens uppdrag ansåg vi det relevant att undersöka.

    Syfte Vår studie syftar till att undersöka fritidspedagogens värdegrundsarbete på fritidshemmet. Fokus ska ligga på varje enskild fritidspedagogs upplevelse och beskrivning av värdegrundsarbetet.MetodVi har utfört en kvalitativ studie då det passade vårt syfte bäst. Intervjuerna genomfördes med oss båda närvarande och spelades in på en mobilenhet. Genom att båda var närvarande kunde en av oss leda intervjun medan den andre kunde föra minnesanteckningar på ett smidigt sätt. Det insamlade materialet bearbetades och analyserades utifrån våra frågeställningar.ResultatVi kan se att det råder lika uppfattningar kring hur värdegrundsarbete kan bedrivas i verksamheten. Däremot råder det olika uppfattningar om vad värdegrunden och arbetet med det innebär. Fritidspedagogernas egna intressen för värdegrunden påverkar hur värdegrundsarbetet bedrivs i verksamheten. Arbetslaget har också en stor påverkan när det gäller arbetet med värdegrunden.
