All from the point of view of three scientist and three persons working with treatment of addicts who were interviewed. The results of these interviews were analysed on an individual level with a psychological theory.
Faderskapsanalys av tallfrö från Västerhus fröplantage : Skillnad i pollenkontaminering mellan öppen pollinering och pollinering inom ett avgränsat system
In this study, pollen contamination (measured by the number of seeds pollinated by pollen not belonging to any of the clones on the seed orchard) is compared between open pollination and isolated pollination environments in a Scots pine (Pinus sylvestris) seed orchard called Västerhus, located outside Önsköldsvik. In this seed orchard a tent experiment is taking place. Skogforsk has built six large tents covering 12-14 trees with each tent. Fertilization patterns were compared between one tree in a tent with a supplementation of pollen from five clones not represented in the tent and another tree of the same clone subject to open pollination outside the tents. By using DNA markers the paternity was determined for 48 seeds from each tree.

De fria- respektive planerade aktiviteternas betydelse för barns utveckling : En essä om faktorer som avgör vilket utrymme som ges de olika aktiviteterna
Early during my education to become an afterschool-teacher a concern was raised that afterschool-programs will continue to be seen as an institution for childcare services. In this experience-based essay, I discuss what I see as the coreproblem: the free- and planned activities. What do the free- and planned activities actually mean for children's development and what is it that determines how much space the various activities will be allowed to take?In my attempts to answer this question, I go through the concept of leisure, the importance of children?s play and adults responsibilities in children?s play, what the different policy documents say about children?s play and the creative work, staff skills and theoretical and practical knowledge. I question whether I was right in the story that I begin this essay with, and conclude that it is more difficult than I previously thought to find an answer to the question..

Galactose in dairy products
Milk and milk consumption has been subject of discussion for a long time, and is still a hot topic. Recently, as study was published that observed a correlation between milk intake and increased risk of fractures and mortality. The authors proposed the milk?s content of D-galactose as the possible mechanism, since D-galactose is used indicated ageing in animal models. Therefore, this study aims to develop a method to determine the amount of galactose, glucose and lactose in milk and fermented milk and apply it on to dairy products on the Swedish market.
Yngre barns möte med matematik
Purpose: The purpose of the study is to find out what mathematical content primary school children encounter in their free options at school.Through observation, the study defines mathematical areas that primary school students encounter in their free options at school. We want the study to show the reader the mathematics that students continuously meet without associating it with regular mathematics as taught in school.A number of mathematical areas have been defined in the analysis of the observations. These areas have subsequently been discussed more thoroughly. Finally, the areas have been arranged in a grid system to clarify the results.In our study, we have discovered that mathematics exists in all the observed situations the students participated in.We believe that observation as a method can give teachers a tool for helping students associate practical actions during their free options with the more theoretical aspects of formal teaching of mathematics. We discuss this further in the study..
Risk eller Resurs: En studie av hur riskbegreppet konstrueras i den svenska kärnkraftsdebatten
Looking at the debate on nuclear power in Sweden, the issue of risk is central to understanding the difficulties in resolving differences between proponents and opponents. I sought to answer the research question: "how is the concept of risk constructed in the nuclear power debate in Sweden?" Four main aspects of risk construction were defined and investigated to identify differences between sides in the debate. Through a qualitative study of the debate and its actors I found clear differences in respect to all four aspects of risk construction. First, the perception of nuclear power as a "normal risk" is common among nuclear opponents in contrast to a largely probabilistic view among proponents.
Pilot study: influence of the Samoan dog population on visitors
A range of public health and animal welfare problems has been shown to be associated with free-roaming dogs. With a high density of free-roaming dogs and with a major tourism industry, Samoan tourists are likely to be influenced by the presence of the dogs. The tourists are mainly from the Oceanic region; with New Zealand and Australia as the biggest contributors. The aim of this study was to examine the potential impacts of dogs on visitors to Samoa.
A questionnaire was handed out to 281 visitors all over Samoa, collecting opinions and information on visitors? experiences and behaviour regarding the Samoan dogs.
Besparingsmodell för produktivitetshöjande arbete inom skärande bearbetningsteknik
The market is developing and a growing competition increases pressure on companies to maintain their competitive advantage. Working with cost savings is a way to enhance earnings in a short term but also in a longer perspective. Volvo Powertrain Production Köping has an overall goal; to reduce costs by nine percentages in three years. To achieve the goal, Volvo Powertrain Production Köping works with World Class Manufacturing where the Department of Processing Technology constitutes an important part.Volvo Powertrain Production Köping lacks a standard for how savings within the metal cutting tool area are to be calculated. This makes it difficult to control and monitor their business outcome but it also causes difficulties in controlling the tool suppliers? outcome.
Icke förnyelsebara risker : Svenska gruvbolags riskhantering av en eventuell framtida metallbrist
A major issue that has been a subject for quite some time is whether there will be a scarcity of metals in the bedrock in the future and whether or not we might end up with a problem similar to that of the big oil crisis in the mid-seventies. Following the oil crisis many oil companies started up with risk management to control future risks. This work presents how Swedish mining companies work with risk management to handle risks that might come up in the future due to metal scarceness. How Swedish mining companies look at the possible metal scarceness and if they use risk management in their decision-making process is studied. By doing interviews with Swedish owned mining companies it was found that the mining companies did not see the future metal scarcity as a risk, even though 2/3 of the companies acknowledged the scarceness to be a reality.
Skatteplanering vs. den optimala kapitaliseringsgraden
This thesis deals with the legislative problem of thin and thick capitalization of subsidiary companies situated abroad. This kind of companies are often used for tax planning purposes, as means for transferring company profit from a high tax state to a low tax state. Today, the legislative flora around the world mainly focuses on the question"how low/high can the capitalization level of the company be, before thin/thick capitalization can be considered to be at hand?". Instead, this thesis raises the question"how far from the optimal capitalization rate is a probable capitalization level for a company, and can this be an alternative approach to legislation?".
Styrr?ntans olika effekt p? bostadsmarknaden - En komparativ studie om hur bostadspriserna p?verkas olika av r?ntef?r?ndringar i stora och sm? st?der.
This quantitative study aims to investigate whether there is a difference in the effect of the policy rate on the price per square meter for condominiums between small and large cities in Sweden. The study encompasses a total of seven Swedish municipalities, of which three located in large cities and four in small cities. Data regarding housing sales and additional variables have been collected for all municipalities, and the price per square meter is the dependent variable in the regressions performed on the dataset, which constitutes the empirical basis of the study. The aim is further to contribute to an increased understanding of how the effect of the policy rate might differ between Swedish cities and why. The results of the study show significant differences in how the policy rate affects the price per square meter in a small city compared to a large city, with the effect being greater in the latter.
