Regionala och sociala skillnader i hälsotillstånd : En jämförelsestudie av Danderyd och Rinkeby
Sweden's population holds today one of the highest life expectancies in the world and an increasing number of Swedes believe that they have good health. However, the problem still remains that there exists significant differences in health between different population groups and neighborhoods. Two neighborhoods that demonstrate high inequality in health status are Rinkeby and Danderyd in Stockholm County. The purpose of this study was to examine why health differs between different neighborhoods and how residents experience the area and their health. To answer this purpose a combination of statistical data and qualitative interviews with residents in Danderyd and Rinkeby has been used with an additional literature review. The study showed that the causes of health inequalities between these neighborhoods was primarily concerned with the factors of education, economic conditions, ethnicity, conditions of comfort and companionship and the surrounding residential environment. The population in Danderyd, made up largely of people with high education, good economic conditions and few foreign-born, while the majority of Rinkeby?s population consists of individuals with low education, poor economic conditions and a high proportion of inhabitants of foreign origin, which are determining factors leading to poorer health status among the population.
Seroprevalens av antikroppar mot Encephalitozoon cuniculi hos friska tamkaniner :
The aim of this study was to determine the prevalence of antibodies against the intracellular protozoan Encephalitozoon cuniculi in healthy pet rabbits. Encephalitozoonosis is an important differential diagnosis to ascending infection with Pasteurella multocida in the ears since a common symptom is vestibular syndrome. Samples were collected from healthy rabbits that were brought to an animal clinic in Stockholm for some kind of prophylactic procedure. The samples were analysed by an India-ink Immunoreaction test / Carbon Immunoassay. Of 106 rabbits 7 (6.6%) were seropositve.
A Long Day?s Journey into Night ? examining the Swedish model, present and future
In this essay we strive to examine how the social work in Sweden will be affected if the Swedish welfare model goes through fundamental changes. The study illuminates the close connection between the Swedish collective bargaining model and the Swedish welfare system. The questions we present in this essay, and hopefully answer satisfactory, are: is the Swedish welfare model subject to thorough changes? How will such a change alter the social work in Sweden?, is the Swedish collective bargaining model in a state of modification? Would a modification in the collective bargaining model have effects on the Swedish welfare model?We have used a qualitative method in collecting empirical material. We interviewed three representatives, who worked for Confederation of Swedish Enterprise, IF Metall and The Swedish Municipal Workers respectively.
Jämförelse mellan MultiScat och konventionell beräkning av intensiteter till koncentrationer vid analys med röntgenflourescensspektrometri
In this master thesis work, a new method called MultiScat, is compared with the conventional method with alfa-correction, for computing concentrations from intensities in X-ray spectrometric analysis. The conventional model is a linear model, which only takes the photoelectric effect into consideration. It doesn't consider Rayleigh and Compton scattering even though it has a great impact on the measured intensities. Here MultiScat differs a lot. MultiScat is based on a solution of the Boltzmann transport equation.
Barns tolkning av en modell för vattnets kretslopp : -förståelse och tillämpning
AbstractThe purpose of this study is to find out how pupils give expression of a water cycle model and if the model causes any misunderstanding. Two problems constitute the starting point for this investigation. The first question is: how do the pupils explain the water cycle with the help of the jar model (can of glass). The other question is: can the children see any similarities between the can of glass and our earth. Qualitative semi structured interviews with seven pupils in the ages of 8-9 have been used to show the pupils? own thoughts and how they express them.
Transferfunktionsmodeller modellering och prognoser av Sjötransportindex
We have by Statistics Sweden (SCB) been given the task of using different dynamic regression models in order to forecast service price index for sea transport. The aim is to see whether these models provide better forecasts than those previously used. This essay aim to identify, estimate and evaluate the selected prediction models. Through our data material we were given access to 28 sightings of sea transport index during the period of 2004 q1 to 2010 q4. We have chosen to evaluate three different transfer function models, one ARIMA model and one naive forecasting model. The input variables we decided to test in our transfer function models were the price of petroleum products, the port activity in Swedish ports and the lending rate of Swedish Central bank. The results of our study suggest that transfer function models generally provide better models than the ARIMA model and the naive forecast model.
Den licensierade vargjaktens betydelse för vargstammen
In October 2009, a new decision was made concerning the administration of predators which resulted in a new wolf policy in Sweden. This meant that the wolf population now should be limited to 210 individuals by harvest. The new policy also recognized that the public acceptance of this species must increase and the genetic status improved. In the 17th of December a decision was taken by the Swedish parliament that it should become legal to hunt wolves in Sweden. The wolf hunt resulted in debate on a large scale amongst people, some thought of it as a good decision while others thought it was wrong.
Simulation of rattan harvests in Indonesia : different harvesting pressures and the resulting patterns
The objectives of this research were to determine whether the natural rattan resources in Sulawesi, Indonesia can cope with the strongly increased harvesting pressure that has occurred over the last centuries. I was furthermore looking for patterns in the rattan population dynamics that might give a hint on how the harvesting system could be improved to ensure a maximum sustainable yield. To
answer these questions, I developed an individual-based model to analyse the dynamics of rattan growth in connection with rattan harvests by locals to identify sustainable levels of rattan harvests around villages in Sulawesi, Indonesia. Scenarios with different harvesting intensities were run to compare the change in harvest amount. For a given harvesting pressure, scenarios with a high number of harvesters and a low harvesting frequency had the same effect as scenarios with high harvesting frequencies and a low number of harvesters.
Parametriserad modell av motorprototyp med Solidworks
The purpose of this thesis has been to build a parameterized model of a prototype motor in the program Solidworks, to use in future optimization of aspects of effectiveness and weight. The result were two models. The first model were one minor part of the whole design in 2D, to be able to optimize and study the minor part with a faster loss simulation. The second model was the whole design in 3D. The whole model were done with the three programs Solidworks, Comsol and Matlab.
Pensionären och paddan : En studie av pensionärers upplevelser av läsplattor
Portable IT devices such as laptops, smart phones and computer tablets are becoming ever more ubiquitous. At the same time, the population of the Western world is growing older, with aging bringing about changes with regards to individuals' physical and mental capabilities. These facts raises important questions about how well suited these devices are for use by elderly people. This study focuses on the cognitive aspects of the devices' usability, using the concept of mental models to analyze the users' understanding of a computer tablet. It also draws upon theory of graphical user interfaces in its analyses.
Kommunernas dolda pensionsskuld
Background: In 1998 it was stated that Swedish municipalities would report the pension liabilities according to the mixed model where the pension liabilities before 1998 was moved from the balance sheet. The mixed model has been criticized by economists for not showing the total pension liabilities. To remove some of the liabilities in the municipalities balance sheets means that the solvency improves. Some municipalities have decided to go against the municipal accounting law and recognize all of the pension liability as a liability according to the full funding model. When two accounting models are being used the comparison of the municipalities' financial statements is much harder.Purpose: The main purpose of this study was to study the reason why some municipalities apply full funding model rather than the mixed model.

Det sjuka benet och de friska människorna : en studie av osteoporos och osteoartrit i kvarteret Banken 1 i Visby
This essay deals with the diseases osteoporosis and osteoarthritis in a medieval population from Visby in Sweden. The aim has been to evaluate to what extent and in what way these diseases have influenced the people of a relatively large harbour town during the Middle Ages. 24 individuals were analysed osteologicaly and 19 of them became subject for measurements of bone density through DEXA readings. Furthermore four individuals were x-rayed based on external differences due to osteoarthritis and a change in the depression at the base of the medial surface of the greater trochanter. Similar studies have been made in Trondheim, Norway and Wharram Percy, Great Britain.
Analysmodellen - en variation i tillämpningen?
The purpose of our essay is to examine if variation exists in the way that auditors try their independence, this so called analysis-model. We will suggest some factors that influence the way auditors practise the analysis-model. The institutional theory predicts no differencies since the normative pressure could be expected to be severe. But we found that among other things people?s qualifications, personalities and audit firm?s size and age influence the way auditors try their independence.
Alva Myrdal och svenskt familjeplaneringsbistånd : Affinitet mellan välfärdsideologi och principerna bakom befolkningskontroll
Around the 1950s an explosive population growth started in the Third World. Parallel with the population growth a global network grew up advocating population control and limited population growth. Sweden had a unique place in that network through a pioneering role promoting the issue in the UN organization. During the 20th century Sweden was a pioneer country in terms of initiatives for population control. Ceylon family planing pilot project was something new in a time when other donors considered family planning be too controversial area for bilateral aid projects.
