?Var är den goda glassen?? : En studie av föräldrar till barn med neuropsykiatriska diagnoser och deras upplevelse av samhällsstödi biografier
AbstractThe aim of this qualitative study was to investigate how parents of children diagnosed with Autism, Aspergers Syndrome or ADHD/ADD describe their experience of the Swedish welfare support system in written biographies. To answer this question a study of five biographies written by parents with children diagnosed with ADHD, Autism and Asperger Syndrome where made. The conclusion was that the social network itself is of great importance to the parents. Families with single parents experienced a less positive experience of the Swedish welfare support system than parents with a spouse. The study also reveiled that families with a supporting social network and a solid financial ground in combination had the best experience of the Swedish social welfare support system.
En komparativ studie av vinstdelningssystem bland advokatbyråer
Law firms are defined as knowledge-intensive companies. Due to the dependency regarding the resource of knowledge among the firms employees and to the fact that they often are categorised as a type of professional service firm. The purpose of this study is to investigate the different types of profitsharingsystems as a form of reward with focus on the theoretical differences and effects of the True Partnershipmodel and the Stockholmmodel. In addition to these models we will look into the Human Resource processes of; recruiting, integration, retaining and development of employees. The main purpose of the study is to examine the theoretical level on how the profitsharingsystems effect different Human Resource processes and through the knowledge of these connections using this as an analogy when to analyse other law-firms and knowledge?intensive company?s.
Metod för inventering av underhållsbehov för skogsdiken
Large areas have been ditched in Sweden during the past 100 years to improve the forest production. Ditching and also maintenance of old ditches are operations having mainly negative effects on water quality, flora and fauna and changing characteristics of soil. The purpose of this study was to suggest a method for inventory of the need for ditching maintenance in old forest ditches that takes biodiversity, water protection and forest production into consideration. Inventory methods from five Swedish and Finnish forest companies, agencies and organisations were compared. Their employees were interviewed about their handling with ditches, forest production and nature conservation.

Effects of palmitic and stearic acids supplementation on milk yield, composition and milk lipolysis in dairy cows
When facing the fact that high yielding dairy cows has an increasing energy requirements, the practice of adding lipid supplements such as concentrates rich in palm oil and/or palm oil industry by-products become more common. Palm oil containing high levels of C16:0 causes high levels of free fatty acids (FFA) which are linked to larger milk fat globules (MFG) which affect the reaction of lipolysis resulting in rancid flavour and processing problems. Instead of using palm oil, rapeseed oil rich in C18:1 C18:2 can be used. In order to evaluate the effect of
added C18:0 and C16:0 on milk lipolysis, 30 Swedish Red lactating dairy cows including 15 multiparous (MP) and 15 primiparous (PP) cows were randomly divided in three groups
resulting in 3 10 cow-groups (5 PP and 5 MP cows per group) and fed one out of three concentrate mixtures: control (C), a standard concentrate mixture with no fat added; palmitate
(P) as C plus the addition of palmitate methyl ester (10 % in DM basis); and stearate (St) as C plus the addition of stearate methyl ester (10 % in DM basis). Milk yield was registered, and milk samples were collected and analysed for milk composition, FFA content and size of MFG.
Torkning av flis med restvärme : Metoder för att sänka återledningstemperaturen
The purpose of this study has been to evaluate whether a Low temperature bio-mass dryer could be integrated with the local district heating system in Malå. The aim is to increase the thermal efficiency of the cogeneration plant in Malå, by lowering the temperature of the cooling medium. Another benefit that comes from this is improved combustion efficiency at the power plant, since drying the fuel causes an Increase of the heating value.Simulations has been made in Excel, and with use of linear regression, to find out if it is profitable. Data for this purpose has been supplied by the power company Skellefteåkraft and furthermore SMHI.The result of the Calculations shows that a very efficient bio-mass dryer is needed, if yield of investments should be made possible. An Investment of 4,27 Mkr, in a dryer, could at a such criterium return 60000 kr/year, if the price of the biomass is 190kr/MWh.
Assessing the ability of LARGE overexpression to prevent the development of muscular dystrophy
Duchenne Muscular Dystrophy (DMD) is a hereditary X-linked fatal disease that affects 1 in 3500 male births. It is the most common kind of muscular dystrophy in children and leads to death in the late teens or early 20s for many patients. The mdx mouse is a model of DMD that can be used to investigate experimental therapies. Overexpression of a glycosyltransferase, CT GalNAc, in mdx mice has been demonstrated to prevent the development of muscular dystrophy. Overexpression of another glycosyltransferase, LARGE, is currently being investigated as a treatment for another group of muscular dystrophies, the dystroglycanopathies.
In this study, we overexpressed LARGE in mdx mice in order to investigate its effect on the development of muscular dystrophy.
Powerplay En studie om de stora sporternas numerära överläge i svensk press
The purpose with our study was to see if and how the amount of articles regarding different sports has changed during the last three decades. If it had changed our target was to se how and why it had changed. We have performed a quantitative content analysis. In the analysis we have studied the two national Swedish newspapers Dagens Nyheter and Aftonbladet. In doing so we have created two synthetic weeks in each of the years 1986, 1999 and 2012.
Hållbar design för en bättre värld -med hemlösa i fokus
The aim of this project is to examine the needs and problems that exists amongst homeless people and to develop a solution that will help them in their everyday life. Since the homeless are a relatively large vulnerable group i Sweden, their everyday lives could be made easier in many ways.A clear definition of the target group is put together to create a good starting point. What state and help orginazations do to help the homelss and the society?s view of the homeless is also relevant and has been documented. Four personal stories have been put together to desicribe cases of clear problems existing in everyday life.Several interesting problems has been defined from the research and acceptance in the communtiy, desire to be seen and heard and a lack of confidence were the main needs.
En novellsamling blir till
This essay discusses my proposed collection of short stories. The aim has been to examine the texts in terms of form and thematics, and position of the texts in a social context. First I present the collection, and then look at the texts from stylistic angle. I have chosen to use the concept of descriptive style. I have picked out certain parts of my texts in order to see which effect they have on the reader (in this case I).
Effekten av metyljasmonat som skydd mot gnag av snytbagge (Hylobius abietis) på gran- och tallplantor :
The effect of methyl jasmonate on resistance against the large pine weevil (Hylobius abietis) in Scots pine and Norway spruce seedlings.
A field experiment was conducted in order to determine the dose-response effects of methyl jasmonate (MJ) on growth and defence to pine weevils in Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) and to compare the effect of MJ between pine and spruce.
In addition a complementary greenhouse experiment was conducted with the same aims as above and to determine the amount of resin ducts and their correlation to the feeding of pine weevils.
The field experiment was conducted on a fresh clear cutting in Garpenberg, southern Dalarna in central Sweden. The experiment consisted of 30 blocks with three kinds of containerized seedlings: 2-year old spruce, small pine (before shoot elongation) and 1-year old pine (already shoot elongated). They were all exposed to 4 treatments 14 days prior to the experiment: control, 25 mM/L MJ, 50 mM/L MJ and 100 mM/L MJ. Data on weevil damage and seedling growth were collected after the first and the second growing season.
The seedlings in the greenhouse experiment were of the same kind and were exposed to the same treatment as the ones in the field experiment.
Kolbalansen vid olika skötselstrategier för skogen på Tagels fastighet.
Since the 19th century the concentration of CO2 in the atmosphere hasincreased by 40 percent as an effect of the use of fossil energy sources.Increased concentration of CO2 will likely lead to increased temperature,changes in precipitation, rising sea level and increased frequency of extremeweather like storm events. A step to reduce emissions of CO2 and mitigateclimate change, for the property of Tagel, can be to adopt new silviculturalstrategies and analyse which is the most effective. As a result of that, threescenarios was produced, business-as-usual (BAU), increased set aside landand energy. An introduction of windpower at Tagels estate (property) andeffects on carbon balance was also examined. By using the Heureka systemand LCA-analysis in this study, it showed that the scenario of increased setaside land was the most efficient way to reduce carbon dioxide (CO2)emissions for the analysed period of 100 years.
Holländska sjukan En litteraturstudie om effekterna av holländska sjukan på Botswanas textil- och boskapsindustri.
Botswanas ekonomiska tillväxt utgör ett sällsynt exempel på ett afrikanskt land som har lyckats använda sina naturtillgångar till att driva på en ekonomisk utveckling och samtidigt minimerat effekterna av den så kallade Holländska sjukan (HS). HS är ett ekonomiskt fenomen som går ut på att en växande sektor som baseras på naturtillgångar skadar landets tillverkningssektor och leder därmed till en indirekt de-industrialisering. Botswanas diamantindustri står för drygt 35% av BNP:n och hela 75% av exportintäkterna vilket gör att landet har en mineralbaserad ekonomi. Detta faktum har gjort landet väldigt intressant för forskning. Aktuell forskning har med hjälp av ekonometriska metoder visat att landets tillverkningssektor har undvikit eller drabbats minimalt av de effekter som HS utgör.
Local poultry production in rural Zambia and the effect of light on poultry performance
Zambia is a country in Southern Africa where poverty is widespread and the traditional keeping of local poultry therefore plays a crucial role in improving nutrition. Meat and eggs from poultry are important sources of protein but also of income. Improving the poultry production is thereby a method to fight poverty. For poultry, the access to light is an important factor for both growth and egg production. In this paper, the focus is on the traditional village chickens used for both egg and meat production, how they are kept, their health and welfare and if the use of a solar lamp will influence their behaviour, growth and egg production.
Three studies were conducted in Chibombo and Choma Districts in Zambia were 17 farmers were interviewed regarding the village chicken management of which six farmers participated in a solar lamp experiment.
Effekterna ligger i betraktarens ögon - En studie om effekter av videopresentationer inom e-handeln
Companies within the e-commerce industry currently try to overcome the disadvantages of not being able to provide a physical inspection of products, and this is especially an issue for the apparel industry. One way of trying to overcome this issue is by presenting apparel with a short video of a model wearing the garment. The aim in this thesis is to investigate how these video presentations affect consumers' emotions, cognitions and intentions. Since previous studies have found that different shopping scenarios can moderate the effect of stimuli in the atmosphere on the consumers' emotions, we also aim to see if a video presentation, depending on the shopping scenario, could have a negative impact on site visitors. Moreover this thesis investigates the moderating effects of involvement on consumers' cognitions.
