Vägval: kortast, snabbasteller hälsosammast : En försöksmodell i GIS för ruttoptimering och beräknad inhalation av luftföroreningar för cykelrutter
Cycling is one of the most sustainable transport modes available and it is widely promoted inmany urban areas. The health benefits from cycling has shown to be substantial, includingdecreased risks of diseases related to overweight and enhancing brain capacity. However, inurban areas cyclists can temporaly be exposed to high levels of air pollution, resulting inhealth risks as opposed to health benefits.The objective of this thesis is to develop a rasterbased test model in GIS that estimates theinhaled dose of air pollution for cyclists based on relative particle concentration in differenttransportation micro-environments. The method used is a least-cost path approach,calculating three different routes; shortest, fastest and least dose for four different trips withinSödermalm, Stockholm.The results show that the inhaled particle dose can be greatly reduced, 39% - 58% for three ofthe routes, by choosing the least dose route. One of the most interesting findings is thesubstantial increase of dose when high levels of particles are combined with uphill cycling.The conclusion for the thesis is that a raster-GIS model can be very useful for estimating doseof different air pollution particles and chemicals along cycling routes.
Vad får jag egentligen skriva om min arbetsgivare på facebook och andra sociala medier? : Yttrandefrihet möter Lojalitetsplikt
In today's society the borders between work and leisure blurs out more and more, and just as we might bring our work home, we might as well take our leisure to work with the help of so called smartphones with constant connection to social networks such as facebook and twitter. But what happens when the small talk around the coffee machine in the workplace gets out in public spaces? Instead of complaining to my closest colleague when my boss is acting like a fool or when my workload sky rocketed, I might now instead update my status on facebook with my complaint. But what am I actually allowed to write about my employer? And has the employer any possibility to act legally in respond to what I write?For the younger generation, who more or less is grown up with these social networks, I think this demarcation can be difficult to draw and understand.In this essay I deal with the issue of whether a principle of law, such as the duty of loyalty might collide with my constitutional right to use freedom of speech against my employer..

BLOD, SKATT OCH JORDEB?CKER. En j?mf?rande fallstudie om informationskapacitet i det postkoloniala Latinamerika
Tax revenue is crucial in order for states to survive. States vary a lot in terms of tax revenue
however, and different explanations are frequently debated among political scientists. Recently,
scholars have argued that the variations in tax revenue among European states today can largely be
explained by their ability to collect information about the citizens and their belongings during the
early modern period (1450-1800). States that were early in acquiring this information in so called
cadasters, could use it in order to collect tax. This fiscal capacity thereafter sustained in a path
dependent manner.
Smarta lokala energisystem, Vision-Teknik-Tillämpning
The energy sector is facing an impending paradigm shift. Today?s technology enables the end-user to generate their own energy locally at home. Furthermore, recently developed storage technologies make it possible to balance energy demand with stored energy and integrate district heating with the local power grid. This means that in the future heat and electric power will interact and energy flows is converted over energy boundaries.
Jämförelse av beräknad och verklig grundvattensänkning vid vägportar
Present master of science thesis has been carried out at the Swedish Road Administration consulting services (Vägverket Konsult) in Karlstad. The purpose of the study is to investigate how well the calculated drawdown of the groundwater table predicts the actual drawdown when the road and railway gates at the studied sites are built. For this purpose the groundwater levels at the three bridges were measured during 6 months. The bridges in question are two railway bridges situated in Ölme and Ulvåker and one road bridge crossing a pedestrian and cycling path in Lidköping.In Ölme the calculated area of influence was smaller than the measured one. It differed up to 30 meters, i.e.
Ledarskap i kris : En studie av ledarskap i ekonomiska kriser
Syfte: Att undersöka vad som utmärker ledarskap i ekonomiska kriser, till följd av den idag aktuella finanskrisen.Genomförande: Empirin har insamlats med hjälp av den kvalitativa metoden. Studien innefattar djupintervjuer med semistrukturerade frågor och tio respondenter från två olika företag inom banksektorn. Utifrån empirin har författarna försökt att dra paralleller mellan ledarnas beteenden och de teorier som omfattar olika ledarstilar.Slutsatser: Utifrån analysen av empirin framgick det att ledarbeteenden i ekonomiska kriser skiljer sig. Dock kan orsaken till det vara företagens olika förutsättningar och struktur innan den ekonomiska krisen. Beteenden som tydlighet, tillgänglighet, delaktighet, samhörighet och minskat handlingsutrymme blev mer utmärkande.
X-it :en studie om f.d. narkotikamissbrukares erfarenheter
The purpose of this study was to get a client perspective of the different ways to exit from a different role as a drugabuser, and furthermore, how to maintain a drugfree life.The questions of issue were:- What kind of social-psychological conceptions rules the process?- Which motive powers are essential to maintain drug-independence?- Are there any difficulties on the path to social adaptation?Our research was based on interviews with eight persons; five men and three women, from a treatment home in the south of Sweden. The method we used was semi-structured and with a thematic questionnaire. We chose this form due to the fact that we did not want to influence the interviews, as we wanted to know the persons opinions.The result of our study showed that the interviewed persons have some difficulties to adjust in the society and to find new friends especially the interviewed persons with maintenance treatment. Marginal problems as, for example, the lack of not having a work or a home can complicate a further development for the group with maintenance treatment.
En avdemokratisering av förvaltningen? : - En analys av socialförsäkringsnämndernas avveckling och dess effekter
Swedish public administration has for the last few decades undergone reforms aimed at making it more efficient. A substantial part of these reforms have concerned creating clearer roles for politicians versus officials in the public sector, i.e. giving politicians a responsibility for setting goals and steering activities and public officials the role of implementing them.This study aims to examine one reform following this path that is under implementation in a Swedish public authority; Försäkringskassan, the Social Insurance Agency. The purpose of the reform is to increase the organization?s effectiveness and the rule of law.
Främling, Paprika och Alienation : en studie om den offentliga skulpturens betydelse för miljön i Borlänges stadskärna
Offentlig skulptur är en viktig del av ett samhälles/en stads offentliga miljö. Tillsammans med arkitekturen blir det samhället/stadens ansikte. 1960-talet var en brytningstid, konstdebatten tog fart i Sverige en ny generation konstnärer var på väg. De var gränsöverskridande både i fråga om uttrycksmedel och tekniker. Konsten fick en ny funktion, den skulle förmedla ett budskap den skulle ta ställning i samhällsdebatten.
Framtiden för besättningar med bundna mjölkkor : vad mjölkproducenterna själv tror
De senaste åren har mjölkbesättningarna i Sverige förändrats. Det mest dominerande sättet har varit att hålla korna bundna men efterhand som mjölkgårdarna har rationaliserats och blivit modernare har det blivit vanligare att många lantbrukare ställt om till lösdrift. År 2007 bestämde jordbruksverket att alla nya stallar som ska byggas för mjölkkor ska vara lösdriftssystem, vilket innebär att våra bundna besättningar kommer försvinna i framtiden. Det här examensarbetet har ställt frågan till mjölkproducenter med bundna kor hur de ser på framtiden för sina besättningar.
Idag (2011) finns det 348 100 mjölkkor i Sverige. Av dem står ungefär hälften i uppbundna system.
Klassresan: akademiker av första generation
Vi har i detta arbete med hjälp av genomförda djupintervjuer, samt tidigare forskning i ämnet försökt att belysa åtta individers "resa" genom utbildningssamhället. Detta från ganska enkla förhållanden, till positioner som kan betraktas som tämligen unika sett till deras ursprung, samtid och samhällsklass. Vi har utifrån dessa personers berättelser sedan försökt knyta an till den allmänna samhällsutvecklingen, likväl som utbildningssituationen sett över tid. Detta för att på så sätt åstadkomma en helhetsbild i ämnet. Intervjumaterialet har sedan sammanställts i olika teman där intressanta beröringspunkter men även särskiljande drag lyfts fram.
Svenskt barnbildarkiv (SBBA) ? Barnbilder, bildindexering och digitalisering
The aim of this thesis is to examine the possibilities and challenges facing an archive, Svenskt barnbildarkiv (SBBA), if to publish its material online. Our context for this study is image indexing. Our main questions are: How can SBBA index their pictures for a possible publication on the Internet? Are there any pros or cons in the determination of topics in children?s images, and in that case, which? What search paths are important when indexing children?s pictures, and why are they important? To answer these questions, the thesis is built on a wide study of interdisciplinary literature. But also on SBBA: s own handbook for image ?registration?, and on interviews with the persons working at the archive SBBA, in Eskilstuna.
Ickeheterosexuella kvinnors upplevelser av samhällets attityder gentemot dem - en intervjustudie om attitydförändringar
Syftet med uppsatsen har varit att utifrån perspektivet att socionomer inom olika
verksamheter är i behov av att veta hur ickeheterosexuella kvinnor känner sig
bemötta i samhället ta reda på just de subjektiva beskrivningarna av detta. Detta
har gjorts genom intervjuer med sex stycken ickeheterosexuella kvinnor i åldern
20 till 45 år. Materialet har visat att synlighet i media kan spela roll för samhällets
attitydförändringar. De senare årens lagar har också av mina intervjupersoner
upplevts spela roll för attityderna. Även ålder och generation verkar kunna spela
roll när det gäller öppenhet och attityder till ickeheterosexuella kvinnor..
Tillämpning av GIS-analyser i MKB
The reason for performing an Environmental Impact Assessment (EIA) is to incorporate environmental concern in different kinds of plans and projects. The purpose of such an assessment is to identify and describe direct, indirect and cumulative environmental impacts.Geographical Information System (GIS) is a tool that can be used to combine spatial extension of both sensitive areas and different environmental impacts in a quick and easy way. Because of that, descriptions of environmental impacts and motivation of different standpoints on a specific issue can be more correct and easier to make if GIS is used as a tool.Hence, GIS can contribute to improve the quality of Environmental Impact Assessments. If the benefits of using GIS are to out weight the costs, geographical information of satisfactory detail, actuality and accuracy need to be available at reasonable prices.In this paper, case studies are carried out for three different geographical analyses to investigate the use of GIS as a tool in EIA. From these case studies, more general conclusions about the benefits and limitations of using GIS for Environmental Impact Assessments are also drawn.
