Psykometrisk prövning av PG-13; ett självskattningsinstrument för ihållande sorg
Frågan om ?normal? respektive ?patologisk? sorg har under en lång tid varit ett omdiskuterat ämne inom psykologin och psykiatrin. En grupp forskare har tagit fram kriterier på ett syndrom som fått benämningen ihållande sorg (?prolonged grief?). Studier har visat på att ihållande sorg är ett distinkt syndrom separat från depression, posttraumatisk stressyndrom och generaliserat ångestsyndrom.
Effekter av studie- och yrkesinriktad vägledning på gymnasieskolan ? Effekter av vägledning, avseende gymnasieelevers valda program
The purpose of this study was to investigate the effect of educational and vocational guidance, refer-only high school students tend to stay on their first selected program or to change the program.

Att identifiera uttryck
The aim of this thesis is to analyse the possibility to identify the FRBR entity expression from existing catalogue records performed within the context of Swedish cataloguing rules. The empirical study uses a sample of records from the catalogue within the library at the University College of Borås. To begin with, the thesis reports some of the earlier discussion about the FRBR model. That gives an understanding of which problems the model has and justifies the study?s delimitation towards expression.
Direktsamplande digital transciever
Master thesis work at ITN (Department of Science and Technology) in the areas of A/D-construction and RF-circuit design. Major goal of project were to research suitable possibilities for implementations of direct conversion in transceivers operating in the 160MHz band, theoretic study followed by development of components in the construction environment Cadence. Suitable A/D- converter and other important parts were selected at the end of the theoretic study. Subsampling technique was applied to make A/D sample requirements more realistic to achieve. Besides lowering requirements on A/D-converter it allows a more simple construction, which saves more components than subsampling adds.
Piotroski ur ett riskperspektiv : En empirisk studie av 3- samt 4-faktors CAPM
An efficient market implies that the use of fundamental analysis should not result in excess return, and that any return exceeding the market average can be explained by compensation for risk, accord-ing to The Capital Asset Pricing Model (CAPM). The focus of this study is to test whether the suc-cessful investment strategy developed by Piotroski (2000) generates excess return on American data, after risk adjustment by using Fama & French?s (1993) 3-factor and Carhart?s (1997) 4-factor CAPM. Initially we form stock portfolios based on companies characterized by high book-to-market values, additionally, we divide them into different performance classes by ranking them with Piotroski?s (2000) measure of financial performance, F_SCORE.
Behandlingsresultat av kliniska mastiter : en studie av mastitbehandlingar utförda i mjölkkobesättningen på Jälla naturbruksgymnasium 1997-2008
Mastitis is an important disease in dairy cattle. It is very costly for the farmers and affects a large number of animals. Few studies have been made investigating the outcome of treatment for acute clinical mastitis under Swedish conditions, and it can be problematic to use the results in foreign studies since both the microbial flora as well as treatments may be different from the situation in Sweden. In this project we have investigated data on clinical mastitis and antibiotic treatment in the dairy herd at Jällaskolan, Uppsala based on recordings during the last ten years. The material includes both Swedish Red (SRB) and Swedish Holstein (SLB) breeds, which have been kept at the farm under similar conditions.
When does the protein profile in milk normalize after antibiotic treatment against clinical mastitis?
Concentration of protein in bovine milk is one of the most significant milk quality parameters, to a large extent determining the price for milk to the producer. Mastitis is a common disease among dairy cows, negatively affecting not only milk yield but also milk protein composition. Milk from mastitic cows tends to have lower cheese yield, negatively affected processability properties and sensory quality, due to changed protein quality and composition. Poorer milk protein quality would have an economically negative impact on dairy industry. Only few studies have investigated the short term effects of mastitis on milk protein composition.
Varför var det så svårt? : En flermetodsanalys av läsbarhet av nyhetsartiklar i Dagens Nyheter under 15 år
The aim of this study was to examine the readability of news articles published in the Swedish national newspaper Dagens Nyheter during the years 1999 - 2013. Our hypothesis was that the written language in newspapers is simpler today than it was 15 years ago. To measure the possible change of the written language in a quantitative study we chose to use a method to calculate the readability of 30 news articles, two from each year. We could not see any development of the language level so we chose to do a complementary qualitative study of the layout and presentation of the news articles. This secondary study showed a significant change in how news is presented throughout the years.
Faktorer som inverkar på kvinnors val att söka vård för urininkontinens : En litteraturstudie
Abstract:Theoretical framework: The Theory of Suffering by Katie Eriksson was used.Aim: The aim was to illuminate factors that influence women?s choice to seek care for urinary incontinence.Method: This literature review was based on a sample of nine qualitative and quantitative studies. Modified templates were used to assess the quality of the studies. Analysis of the results was done withmanifest content analysis.Findings: Findings made clear that the experience of shame is a central factor for women not to seek treatment for their urinary incontinence UI. Women had to have severe loss of quality of life in order to seek help for their UI, and the loss of quality of life had to be subjectively larger than the feeling of shame.
Svenskt tullskydd. En studie av svensk protektionism under trettiotalet.
This paper attempts to study the Swedish tariffs during the interwar period in order to asses the level of protectionism in Swedish tariff policy during the period. It is foremost the nominal tariffs that are studied, however an estimate of the effective rate of protection of the tariffs is also calculated for a number of goods. In order to asses the level of protectionism, the Swedish tariffs are also compared with Finnish tariff levels during the interwar period.The sample of Swedish tariffs that have been studied in this paper include the fifteen most important kinds of import goods and the fifteen most important kinds of export goods. The nominal tariff of each kind of goods have been weighted by their share of the total import value.The Swedish specific tariffs did not change much during the interwar period except for a few goods such as petroleum, coffee and automobiles. The fluctuation in nominal tariffs were in most cases the result of the steep fall in prices during the period.
Logistik i små företag - En analys av problem och möjligheter för STARKA
In order to suggest improvements for the logistics of STARKA, we felt that we had to analyze all the activities which were related to STARKA's logistic processes. Our primary analysis consisted of a rough but comprehensive description of different functions in the company, and the relationship between them. This was performed by following a typical order through the company to see which functions were affected by the order.Since we needed a more thorough view of the company, we decided to analyze the different products STARKA currently has on the market, focusing on economic data such as turn-over, profit, profit margin, deficiency cost and cost of warehousing. We also analyzed the company's choice of manufacturing processes, organization, warehousing processes, strengths and weaknesses.These analyses gave us a clear understanding of the company and its processes. STARKA is a small, function oriented company with a wide range of products.
Straff utan Brott : En studie av män som fått sina öron avhuggna i Irak
This is a study of seven men that have suffered from a cruel punishment. The punishment involved getting their ear/ears cut off, prison with more torture and their families being deported from their homes to another town.My sample involved seven Iraqi men who suffered from this punishment during Saddams regime, they got this punishment because they refused to fight against Iran and Kuwait. I went to Iraq and met with the men in person and did interviews with them to understand the effect of the punishment on their personalities, and how the punishment have influenced their lives and interaction with other people in the society and around them.The study focuses on their suffering and how they have been able to live with this stigma.

Estimation of reindeer lichen biomass by image analysis
During consultation procedures between forest owners and the Sámi, data on, e.g., reindeer lichen biomass on the current site is needed. Hitherto, the existing methods of measuring lichen cover and biomass has been either objective methods such as the Point Intercept method, which is time consuming, or some sort of subjective visual estimation, which is faster but less accurate. However, both these methods are sensitive to different observers and/or to different inventories. This paper addresses the further development and evaluation of a photographical inventory method that uses colour distribution in images to estimate lichen biomass. During the autumn of 2011 six different locations, with different grazing pressure and lichen cover, in Norrbotten county were inventoried using both the Point Intercept method and the photographical method, complemented with collection of biomass samples.
