"Kuratorns roll? Grundtanken är väldigt positiv": en undersökning om sjuksköterskors syn på kuratorn i den medicinska organisationen
In this master thesis, which is made in a qualitative manner, we have as purpose to investigate the nurses' estimation of the hospital welfare officer. We find it interesting to take a closer look at their opinion, because of our earlier, bachelor thesis, based on the same subject, only then in the welfare officer´s perspective on themselves. We have interviewed ten nurses and our questions at issue were the following four: Where in the hospital´s hierarchy do the nurses place the welfare officer? In what way do the nurses look at themselves and on the fact that they are leagally authorized? How do the nurses define the welfare officer´s occupational sphere and his part of the medical care? Which opinion do the nurses have on the co-operation with the hospital welfare officer? The primary information, together with two maintheories and a collection of litterature on the subject have helped us to answer the four questions of issue. We have found that the results we see, in some ways are compareable to our first investigation.
Effektivare ytterbelysning inom Karlstads Bostads AB :
This report is an inventory of the street lighting in half of the residential estates owned by Karlstad Bostads AB, a public housing company. The inventory was made to reduce the environmental impact of the street lighting. From the inventory an estimation of the total installed power and the energy consumption was made. The total estimated power of the street lighting was 125 kW and the energy consumption was 500 000 kWh/year with an estimated running time of 4 000 h/year. The dominating source of light was 125 W discharge mercury lamps.
Nytta, skada och kostnader vid screening för bröstcancer med mammografi
The efficacy of screening for breast cancer with mammography has been a subject of controversy during the last decades. However, the general opinion is now that screening reduces mortality in breast cancer (Zackrisson, 2006). It is nevertheless important to weigh the efficacy against the harm and costs associated with screening. Cost-utility and cost-effectiveness analysis of screening have generally failed to incorporate side effects such as anxiety and discomfort related to screening tests and the following diagnostic tests (Gyrd-Hansen, 2000). This study seeks to include such side effects in a cost-utility analysis.
Undervattensvågbrytare - En modellstudie
Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

Utveckling av en metod och en utrustning för mätning av bränslesprayers rörelsemängd
A new type of device for measuring thev m& ?rate of fuel sprays from a diesel fuel injector has been developed and the various steps in the development are described. The device works by deflecting all of the sprays from the injector at the same time by using a bell shaped deflector. A load cell consisting of a machined steel part with strain gauges mounted on it measures the resulting force. The shape of the curvature in the deflector bell shape has been evaluated by photographing the flow in a 2D?version of the curve shape.
Djurskyddsinspektörer : - Behovet av kunskap om exotiska djur
Psittacines and reptiles are exotic animals that are difficult to care for and it requires extra knowledge to make a correct assessment of their wellbeing. An animal welfare inspector, with an education in general animal welfare, may not have a deep enough knowledge of exotic animals to do a proper assessment of the animal?s general condition and its environment. In this paper it was therefore examined if animal welfare inspectors have enough knowledge to do a satisfying inspection of establishments working with selling of exotic animals. A literature study was used to examine difficulties with each species.
Självskattning av depression hos patienter med hjärtsjukdom : Validering av självskattningsformuläret ?Känsloläge?
AbstractObjective: The aim of this study was to investigate the statistical properties of a self-assessment instrument for depression, Känsloläge, with regard to validity, reliability and factor structure. Method: The data collection method used for the study was mail questionnaires. The sample consisted of patients who had received treatment for heart failure, arrhythmic disorders or coronary heart disease at a hospital in Uppsala, Sweden. The study population consisted of 53 patients. The self assessment form?s validity was analyzed by measuring the criterion validity.
Inhibiting the IGF-1 receptor with the cyclolignan Picropodophyllin: an in vitro study of ovulation, implantation and receptivity in a mouse model
Picropodophyllin (PPP) is an analogue of the anti tumour lignan podophyllotoxin with the unique ability to selectively inhibit the receptor of Insulin like growth factor 1(IGF-1). IGF-1 is believed to play an important part in development of the endometrium facing implantation. With PPP treated mice, studies can be made to measure gene expression from tissue of both treated and untreated mice to compare the role of IGF-1 regarding ovulation, implantation and receptivity. The aim of this study was to analyze gene expression of some steroid hormone receptors and cytokines in ovaries from mice treated with PPP. In this study, seven mice were treated with PPP at different times and tissue was collected.

Socialt stöd, arbetsrelaterad stress samt fysisk aktivitets påverkan på individens välmående : En kvantitativ fallstudie
Studiens syfte var att undersöka vilken effekt socialt stöd, arbetsrelaterad stress samt fysisk aktivitet har på individens välmående. Dessutom undersöktes vilken påverkan kön och ålder har på individens välmående. Karasek´s krav-kontroll-stödmodell utgjorde grund vid analys av resultatet (Karasek & Theorell, 1990). Studien utfördes på en organisation och bygger på en enkätundersökning (n=124) där bekvämlighetsurval användes. Mätinstrumentet består av fem delar som utgörs av demografiska faktorer, QPS-Nordic (Dallner, Lindström, Elo, Skogstad et al., 2000), MHC-SF (Keyes, 2009), PSS-14 (Cohen, Karmarck & Mermelstein, 1983) samt fysisk aktivitet.

"Som en pusselbit som passar överallt" : En kvalitativ studie om hur gymnasieelever upplever kreativitet på psykologilektionerna
In the nineties, policy makers highlighted the importance of creativity in education in order to nurture entrepreneurs in our society, thus the purpose of this study is to investigate high school students´ experience of creativity in psychology classes. The results are based on qualitative data from four semi-structured interviews with Swedish high school students who study psychology. The conclusions are that the respondents perceive psychology as a very creative school subject in which they can give personal experience as examples, they can give alternative explanations and solutions to problems, and that there are no right or wrong answers which means that they feel encouraged to self-reflect. The teacher is important as the respondents experience her as open, tolerant, and moreover, that she varies the classes, which contributes to a good classroom climate. The respondents also experience a certain degree of freedom when they feel involved and are allowed to influence their education.

Överavkastning genom utdelning
Syftet med uppsatsen är att empiriskt undersöka ifall det är möjligt att göra en överavkastning, genom att konstruera tre olika utdelningsbaserade handels-strategier. Den första handelsstrategin innebär att de företagen med den högsta direktavkastningen köpes och de med den lägsta blankas. Den andra handelsstrategin innebär att de företag med den största positiva utdelningsförändringen köpes och de företag, vilka har den största utdelningsminskningen, blankas. Den tredje handelsstrategin innebär att de företagen med den högsta utdelningsnivån köpes och de med den lägsta blankas. MetodEn eventstudie utförs med deduktiv ansats och kvantitativ metod.
