Downward migration and transfer to plants of radiocaesium in Scottish soil profiles : a comparison with earlier studies
Following the accident at the nuclear power plant in Chernobyl in 1986, great volumes of137Cs were distributed over large parts of the former Soviet Union and Europe. Over Scotland,radiocaesium was deposited as wet deposition. Due to the relatively long physical half-life of30 years, there are still measurable activity concentrations in the natural environment. Thisstudy was made on two organic soils, Knockandy Hill and Rora Moss, situated in the easternpart of the central highlands of Scotland. At these two sites, studies on migration and transferbetween soil and plants were conducted.
Bakom okunnighetens slöja - En studie av religiösa attribut i kundmötet
The thesis is aiming to investigate what happens in the customer-service worker interaction when the service worker is wearing religious attributes. In order to operationalize this the Muslim head scarf, hijab, is chosen as stimuli. Reviewing previous research and theory in this field, it is clear that people have a preference for people that they perceive to be like themselves, this is referred to as homophily. Further on, the study investigates the ethnicity dimension of the service worker customer interaction. Theoretical areas of attractiveness and color are also investigated.
Ett hållbart val för premiepensionen - En studie av miljö/etiskt märkta fonder i premiepensionssystemet
I uppsatsen undersöks hur 11 globala miljö och/eller etiskt märkta fonder har presterat i jämfö-relse med 17 konventionella fonder i det svenska premiepensionsutbudet genom tillämpning av utvalda finansiella prestationsmått. Detta med anledning av att miljö och/eller etiskt märkta fonder har haft en stor framväxt under det senaste decenniet och det finns därför en efterfrå-gan av att klargöra ifall en pensionssparare behöver göra avkall på den finansiella avkastningen vid val av miljö och/eller etiskt märkta fonder. En jämförelse av det statliga förvalsalternativet och 10 globala miljö och/eller etiskt märkta fonder har även gjorts för att undersöka skillnaden av att vara en aktiv respektive passiv premiepensionssparare då antalet som inte gör ett aktivt val är omkring 50 procent. Resultatet visar ingen statistisk signifikant skillnad med avseende på den riskjusterade avkastningen mellan fonder som är miljö och/eller etiskt märkta och fonder som inte tar hänsyn till dessa kriterier vilket överensstämmer med tidigare forskning. I jämfö-relsen mellan det statliga förvalsalternativet och 10 globala miljö och/eller etiskt märkta fonder har det förstnämnda presterat på en hög nivå..
Vad gör en bilderbok lättläst? : En studie av adaptationen av Astrid Lindgrens Emil i Lönneberga
AbstractThe aim of this study is to investigate how a picture book for children is transformed into an easy-to-read version for children who have just started reading. I examine two versions of Emil of Lönneberga. One of the books is the orginal picture book of Emil in Lönneberga and was written by Astrid Lindgren (1963), while the other is an easy-toreadversion of the book, as adapted by the author Helena Renvall (1977). I have conducted a comparative study as a text and picture analysis of the material, with the focus on the adaptation of the original story. The adaptation in this case is a revision intended to make the story easier to read and more accessible to today?s children.
Levande material. En utforskande exposé över vårt förhållande till kroppen som organisk materia
In this project the author made an attempt to, in a short film, visualizean experience of the organic materials that our bodies consist ofand what becomes of it when we die. The intention was to dissect thismatter, break it down to see it in a simpler form and to explore ourrelationship to it, being part of a constant exchange between organicmaterials and having so much power over the environment and otherliving animals. At the very start, the idea was to deal with the relationshipdifferent people have with their bodies. Later in the process, a decisionwas made that the product would be communicating the author?sown experiences of the body materials after studying it and trying torecreate fragments and feelings of them.
Manure evaluation in dairy cows :
Manure evaluation has been suggested as a cheap, fast and easy method which can give information about the digestibility of the ration, the function of the rumen, where in the gastrointestinal tract the feed is digested and the health of the cow.
An experiment was conducted to study how manure evaluation could be used as a management tool in Swedish Dairy farming. Manure was collected from cows on Kungsängen Research Station and from 9 other farms. The manure samples were analysed for dry matter, ash, starch, pH-value and particle size (wet sieved). Also, the consistency of the manure was determined on a 5-point scale and the colour and smell were noticed. Penn State Forage Particle Separator was used for determining the particle size of the roughage.
Förbrukningsreduktion : Ett alternativ till gasturbiner som snabb aktiv störningsreserv?
The gas turbines in the Swedish secondary reserve are reaching the end of their technical lifetime, hence alternative solutions need to be considered. One of the solutions thought to have the greatest potential is the use of so called consumptionreduction. By entering contracts with large consumers, agreements are made to reduce consumption in the event of major disturbances in the power system and thus being used as a secondary reserve. This thesis investigates the feasibility of consumption reduction as part of the secondary reserve. This has been achieved by developing a requirement specification for the disturbance reserve and by studying the technical and economic potential for consumption reduction among a range of consumers.The technical potential for consumption reduction that fulfils the requirements for participating in the secondary reserve are on average 750 MW in SE 3 and 98 MW in SE 4.
Organisationer emellan, En jämförande fallstudie av företagsinkubation
Business incubation is an important force of economic development but relatively unheard of in organization theory. This is partly due to the fact that in organization theory, meta-organization or the organization of organizations has been neglected or left lagging as much theorization has been focused on organizing individuals. With the growing number of business incubators, and meta-organizations in general, the need for understanding a relatively new type of organization is prevalent.This case study of the business incubator Global Business Labs Botswana (GBL) aims to clarify the organizational differences among meta-organizations and traditional organizations on a case level, as well as explain the underlying factors for these dissimilarities. With respect to the nature of this case study no general conclusions are drawn from the results. The inference, however, is that the organization of GBL and its incubated companies differs from the traditional organization in five elementary aspects: the weak hierarchical structure, the operational autonomy of its members, the strong focus on recruitment processes, the member identity and the lack of formal sanctions.
Som att ha ett osynligt koppel på sig : Intervjustudie med tre patienter med erfarenhet av utskrivning från substitutionsbehandling mot opiatmissbruk
Aims: To examine how patients with experience of being involuntarily discharged from medication-assisted treatment with methadone or buprenorphine have coped with the consequences following the discharge. The study also aim to examine how the patients cope with the stigma related to their abuse of heroin and how they manage to cope with the rules regarding themedication-assisted treatment. Method: Three patients with experience of involuntary discharge from medication-assisted treatment have been interviewed. All were heroin abusing men living in Stockholm. The interviewees were recruited through the Swedish Drug Users Union and through a shelter for homeless people with drug problems.
Modellering av uppdragsberäkningar i JAS 39 Gripen
I JAS 39 Gripen finns funktioner, kallade uppdragsberäkningar, som informerarpiloten om hur mycket bränsle och tid som förväntas gå åt för att slutföra detaktuella flyguppdraget. Uppdragsberäkningsdelen är stor och komplex och genomatt göra en modell av uppdragsberäkningarna kan man enklare simulera och verifieradem innan införandet av en ändring. I detta examensarbete har en modellav koden implementerats i MATLAB/Simulink.Under arbetet har en bränsleberäkningskärna och en accelerationsberäkningsfunktionmodellerats. I samband med modelleringen har modelleringsmetoder utvecklatsför vanligt förekommande dataobjekt och funktionaliteter i koden, såsom variabler,loopar och if-satser. En stor del av arbetet har handlat om validering av modellen mot originalkoden.
Härliga hagar och skrämmande skogar : om våra känslor för landskapet och vad de beror på
Do our imaginations of real landscapes get affected by works of art such as paintings, myths and literature? They often give very colourful descriptions in words as well as pictures. Do they actually change our feelings for the landscapes we are in and carry around as images inside?
Close your eyes and take a few deep breaths. Imagine that you are leaning against a wooden fence a mild summer evening.
Vår personliga utveckling av kulturell kompetens efter fem veckors volontärarbete som fysioterapistudenter i Botswana: En autoetnografisk studie
Kulturella skillnader är vanliga och har alltid funnits. Inom hälso- och sjukvård märks detta allt mer och det kan dagligen uppstå problem på grund av kulturella olikheter. Kulturell kompetens innebär att ha en förståelse för andra kulturer och är en förmåga som kräver tid och arbete för att uppnå. Syftet med studien var att utforska utvecklingen av vår egen kulturella kompetens efter fem veckors volontärarbete som fysioterapistudenter i Botswana. En autoetnografi där dagboksanteckningar efter en volontärperiod i Botswana analyserats.
Melankoli och ironi : Strategier för hållbar utveckling
The purpose of this study is to show what melancholy and irony in my poems express and what techniques that are used to accomplish these effects. Many theorists, among them Sigmund Freud and Julia Kristeva, characterize melancholy as an experience of loss, and therefore one of my questions is what kind of losses appear in my poetry. In search for an answer I analyze the texts from both a psychoanalytic and a sociological point of view. In the latter perspective I discuss the postmodern society using concepts from contemporary thinkers like Zygmunt Bauman, Fredric Jameson and Jean Baudrillard. Finally, I also examine if melancholy has an influence on the form of the poems.
Taxöron, EMO-kloner och batcavegother -att vara online bland blommor och volanger : Fem studier om ungdomars livsvillkor och identitetsskapande
Vi kommer i denna antologi belysa ungdomars livsvillkor och identitetsskapande i dagens samhälle. De olika bidragen har sin grund i ett socialkonstruktivistiskt perspektiv, där vi utgår ifrån att vi skapar vår identitet i interaktion med andra. Vi har använt oss av en kvalitativ metod där vi genom observationer och intervjuer har samlat in vår empiri. Empirin har sedan analyserats enligt Grundad teori. Den första studien Raised in black beskriver identitetsskapande genom en subkultur, varför man väljer att tillhöra en subkultur och varför man väljer att lämna den bakom sig.
What helps or inspires busy moms while grocery shopping?
The purpose of this master thesis is to understand how busy moms experience their grocery shopping trips and the in-store environment. In gaining this knowledge, we aim at being able to suggest ways to improve the grocery shopping experience of busy moms; and present insights that can help food retailers in targeting this consumer group in-store. Methodology: We use an iterative approach, and work with photo elicitation interviews. We let our respondents capture their experiences in photographs, which then aid in recalling their memories in follow up interviews. Theoretical perspective: We base our theoretical perspective on environmental psychology where we use the original M-R model, and include personal and situational variables suggested by Bäckström and Johansson (2006); where the latter variable includes the views by Turley and Milliman (2000).
