Vad avgör förmågan att anpassa sig till livet i ett annat land? : En studie bland finlandssvenska kvinnor boende i Schweiz

Syftet med föreliggande studie var att undersöka vilken betydelse finlandssvenska kvinnors upplevda nivå av stress, självkänsla och emotion management (att kunna hantera de egna känslorna) hade för deras förmåga att anpassa sig till en ny tillvaro i Schweiz. Utöver detta syftade studien att klargöra vilka överlappningar som fanns mellan self-efficacy och dimensionerna i Black, Mendenhall och Oddou (1991) modellen över internationell anpassning. Fyra olika skalor användes för att undersöka relationen mellan anpassningsförmåga och variablerna ovan. Resultatet baserat på 35 respondenter visade att anpassningsförmåga korrelerade både med självkänsla och self-efficacy (tilltro till sin egen förmåga). Kvinnorna skattade anpassningen till livet i Schweiz som ringa krävande, hade låga stressupplevelser och en god självkänsla.

Social media & marknadsföring

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.

Åren efter gymnasiet kanske vi läser vidare eller skaffar oss ett jobb utan kvalifikationskrav. Detta gör att vi föredrar att handla våra modeplagg så billigt som möjligt. Såkallat ?fast fashion?, plagg med hög trendfaktor som bara används en säsong, är det som säljer allra bäst just nu.

Då gängkriget blev politiskt En analys av polis, medier och gäng i Köpenhamn

Denna uppsats försöker utreda vilken roll etnicitet spelar i det som betecknas som ett gängkrig i Köpenhamn. Hösten 2008 har ett stort antal skottlossningar ägt rum på Köpenhamns gator, och huvudaktörerna är Hells Angels /AK81 och en rad geografiskt baserade gäng.Vårt tillvägagångssätt har varit att analysera mediers och polisens agerande, men vi har också lagt stor vikt vid insamling av material genom intervjuer med respondenter från Blågårdsplads, Hells Angels, AK81 och Black Cobra. Vi har analyserat detta material med stöd av teorier kring hur etnicitet kan konstrueras och utnyttjas, häribland primordial, socialkonstruktivistisk och instrumentalistiska etnicitetsuppfattningar.Etnicitet har spelat en central roll i konflikten. Medier och polis har genom sin framställning av konfliktens parter bidragit till att konstruera etniska skiljelinjer i konflikten, linjer som primärt går mellan ?invandare? och danskar.

The Life and the death of commercail email : En studie av e-postens geografi  med hjälp av Actor Network Theory

Denna studie belyser svårigheten för teknik och virtuell geografi att nå ut till mottagaren genom en kartläggning av e-postens geografi. För att skapa förståelse och fånga den osynliga processen bakom e-postens geografi  utgår uppsatsen dels från teorin Actor Network Theory (ANT) och dels från intervjuer.Under studiens gång uppstod ny förståelse för e-postens komplexitet och ledde fram till en reviderad syn. I början av uppsatsarbetet betraktades e-posten enbart utifrån sin funktion som aktant och intermediarie men i takt med att undersökningen fortgick framkom att den samtidigt, utöver dessa funktioner, fungerar e-posten som ett heterogent nätverk med betydelsefulla komponenter såsom aktörer och aktanter. Enligt uppsatsens konklusioner är e-postens trajektoria beroende av den strategi som producenten använder under skapandet av elektroniska meddelanden. Ett kontinuerligt arbete mellan producent och konsument krävs för att e-postens trajektoria ska upprätthållas och leda fram till att det elektroniska meddelande som löper igenom det virtuella nätverket når sitt syfte..

Arkeologi och den senmedeltida ödeläggelsen

This essay discusses the width of the late medieval desertion of farms in Sweden from an archaeological perspective. The object of the essay is to investigate if archaeological investigations and research during the last 10-15 years have changed the view of the late medieval desertion in relation to the Scandinavian research project on deserted farms and villages.The essay also deals with questions on causes to the desertion and when desertion occurred. An ambition of the essay is also to give a general picture of archaeological investigations during the last 10-15 years considering the late medieval desertion. The analyses-material consists mainly of reports from archaeological investigations.Most of the investigations analysed in this essay are investigations of single farms. Because of this it is natural these investigations do not say much about the width of the desertion.

Ett flervariabelt feldetekteringssystem för övervakning av bärlagertemperaturen i vattenkraftturbiner

The purpose of this thesis work was to develop an automatic fault detection system for surveillance of bearing temperature in hydropower turbines. The parameters used except the bearing temperature were cooling water temperature and cooling water flow. A simple static model based on data sampled every minute was developed to estimate the bearing temperature. Then a detector for detection of change in bearing temperature based on the CUSUM-algorithm was designed. Since the amount of data was very small the developed model was too uncertain to be used in a working system.The designed fault detection system showed to work well for the available data.

Validering av vattenkraftmodeller i ARISTO

This master thesis was made to validate hydropower models of a turbine governor,Kaplan turbine and a Francis turbine in the power system simulator ARISTO atSvenska Kraftnät. The validation was made in three steps. The first step was to makesure the models was implement correctly in the simulator. The second was tocompare the simulation results from the Kaplan turbine model to data from a realhydropower plant. The comparison was made to see how the models could generatesimulation result that was similar to the reference power station.

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.

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.
