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.

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.
Lantbruksföretagets tillväxtstrategi och finansiella sökbeteende : en empirisk studie av sex lantbruksföretag med tillväxtambitioner
The structural rationalization of the agricultural sector in Sweden has led to many expansive, professional companies orientated towards growth. The agricultural sector is a very capital-intense sector and is characterized by the need for large sums of capital in form of buildings, inventory and arable land. The capital need is especially large for companies who have an ambition of growth and development of the company in the near future.
The study is built upon six cases that all can be categorized as large agricultural farms with a turnover exceeding 20 million Swedish crowns. The companies are located in the middle and in the south of Sweden and are in the sector of primary production with focus on dairy-, pork-, egg-, chicken-, beef-, vegetables- and grain production as well as in the business of refining milk towards consumers.
The study aims to identify the motives and driving forces that lies behind the growth of a farm-based company. The agricultural companies' motive for growth is studied based on which factors that influence the ambition to grow and to what extent these factors accord to the picture given by earlier research of small companies outside the agricultural sector.
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.
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.
Kritisk diskursanalys av skönlitterära genreutbrytningar i folkbibliotekets litteraturförmedlingskontext
This master?s thesis aims to study the practice of separating popular genres of fiction from the rest of the fiction stock, often seen at public libraries. The method being used is critical discourse analysis according to Norman Fairclough?s three-dimensional conception of discourse. The textual dimension of this analysis is the book shelf itself and the sociocultural practice is the everyday practice at a public library of supplying and mediating books to the visitors.
Du väljer själv- En kvalitativ studie av Nya Vägvalet Rosengård
Youth crime is a subject widely discussed in media as well as in the academic field of criminology. One of the topics within the research field of youth crime discusses how to effectively help young people leave a criminal lifestyle behind. It is within this topic that the focus of this essay lies. This qualitative study examines a community based program in the Swedish city of Malmö called Nya Vägvalet (The New Choice of Path, own translation), which works with juvenile delinquents and the issues that surround the youths lifestyle. The aim of the essay is to explore the foundations and methodology of the program, how the methods of the program are put into practice and how these methods compare to what current research findings claim to be effective factors in successful interventions.
Traumatiserade flyktingar i socialt arbete
According to the Swedish Red Cross, there are over 40 million people fleeing from war and conflict around the world. Some of these individuals are suffering from a disorder named PTSD (Post Traumatic Disorder Syndrome). This disorder is caused by previous experience incurred by war, conflict and violence. My intention with this study has been to increase the knowledge about refugees in Sweden suffering from PTSD syndrome. I have performed a study based on a project named Exigo.
Utbytets och malningens inverkan på NSSC-massans egenskaper
Neutralsulfitkokning av björk möjliggör ett högt utbyte av hemicellulosa, vilket bidrar positivt till flutingens egenskaper och minskar vedkostnaden. Neutralsulfitkoket ska avbrytas när delignifieringen nått tillräckligt långt för att veden ska kunna defibreras skonsamt med en rimlig energiinsats, men innan nedbrytningen av hemicellulosa hunnit accelerera. Syftet med detta examensarbete var att undersöka utbytets och malningens inverkan på NSSC-massans egenskaper.En laboratoriestudie genomfördes där massan kokades till olika utbyten och maldes vid olika insatser. Resultatet av den studien användes sedan för att ställa om kokaren och raffinörerna på lämpligt sätt vid fabriksförsöken. Massaprover togs ut efter det andra kvarnsteget och skickades för analys.

The path to welfare - A qualitative study of welfare and social work in Uganda
Uganda är ett av världens fattigaste länder i dag. Med en kraftigt utbredd fattigdom som försvåras av att landet har en bristande demokrati, vilket har lett till utbredd korruption i landet. Vilkoren för att skapa social välfärd och att bedriva socialt arbete är begränsat. Jag har i detta arbete valt att undersöka hur ett antal personer i Uganda med socialt arbete som specialitet, hur de ser på social välfärd i Uganda. Vilka hinder finns och hur ska man kunna bygga upp social välfärd som inkluderar hela befolkningen, var några av frågorna jag ställde mig.
