En psykometrisk utvärdering av det arbetspsykologiska testet Predicting Job Performance
Ett psykologiskt test används främst inom utbildningssammanhang och kliniska sammanhang, men även inom rekrytering, urval och organisationsutveckling. Det finns idag ett flertal personlighets- och begåvningstest som mäter olika aspekter som kan vara relevanta för en organisation. Predicting Job Performance, PJP, som har sin utgångspunkt i femfaktormodellen, är utvecklat av Psykologiförlaget AB och består av två delar som mäter olika dimensioner av personlighet och begåvning. I denna studie har psykometriska beräkningar utförts för att utvärdera instrumentets reliabilitet samt validitet, främst genom test-retest-metoden. Undersökningsdeltagare var 49 psykologistudenter vid Stockholms Universitet.
Frågeställningar vid ombyggnation av kontorslokaler till bostäder : Håltagning i plastgjuten betong
Det råder bostadsbrist i Stockholm, en lösning är att bygga nya bostäder. En annan lösning är att nyttja befintliga byggnader som inte används som bostäder, genom att bygga om kontor- och industrilokaler till bostäder. Det som händer är att industriområden flyttas längre ut från de attraktiva bostadsområdena. Ombyggnationer av byggnader med olika lokalkategorier kräver omfattande bearbetning och samarbete mellan flera aktörer såsom stadsplanerare, byggherrar, arkitekter, konstruktörer med flera. Det finns många aspekter att ta hänsyn till vid ombyggnationsprojekt och vårt mål är att belysa några av dessa.Den här rapporten studerar först och främst konstruktörens roll, vad en konstruktör ska tänka på vid en ombyggnation.
Dynamiska egenskaper hos håldäcksbjälklag belastade med gångtrafik
Concrete floors have traditionally had no problems with annoying vibrations. However with the demand for larger spans the floors need to be made more slender with a higher degree of utilization and lower mass. Therefore new floors may have problems with vibration serviceability. This thesis studies the vibration characteristics of hollow core slabs. The analysis was made in the finite element program Ansys. The hollow core slab was subjected to a varying force simulating one person walking across the slab.
Hur står sig Modigliani och Millers teori om kapitalstruktur under hög- kontra lågkonjunkturer? : en studie av 30 börsnoterade bolag på den svenska marknaden
Problem formulation: This paper will examine how the capital structure of firms affects their market valuation by applying the Modigliani-Miller theory on Swedish listed companies in a boom and a recession. The study will examine whether it is possible to draw any conclusions as to whether companies with high debt to equity ratios are valued lower in a recession, in comparison to companies with low debt to equity ratios.Purpose: To empirically test the Modigliani-Miller theory of capital structure in a boom and a recession in order to see if the companies? market value is affected differently depending on whether they have a high or a low debt to equity ratios.Methodology: The essay has a deductive and a quantitative methodological approach. Data analysis was done through a correlation analysis, a regression analysis and a hypothesis testing.Theory: The Modigliani-Miller theory of capital structure with taxes states that companies with a high debt to equity ratios has a higher value. One of the risks with a high level of debt could be that during a financial downturn companies have more difficulty realizing capital and are thus more likely to go bankrupt.Conclusions: The study shows results that are contrary to the Modigliani-Miller's theory; all the correlation analyses between debt to equity ratios and market value are negative.
Tre studenter med ADHD berättar om upplevelsen av att läsa i högre utbildning
Research shows that there is a lack of knowledge of adult students with ADHD. Most of all research focuses on children with ADHD in school. The purpose of this study was to gain a better understanding of how adult learners with ADHD experience academic studies related to cognitive difficulties, emotion, motivation, and their experience of SOC. The questions tried to determine how any cognitive difficulties and emotions are perceived, how students' motivation to study impacted and their experience of SOC based on studies in higher education. To answer the purpose and questions used qualitative interviews based on three students with ADHD using a hermeneutic method.
Rörlig lön
Det är en ständigt pågående debatt om huruvida belöningssystem fungerar som motivationsinstrument eller inte. Många, främst inom den psykologiska skolan, är kritiska till belöningssystem, trots detta finns de i alla organisationer. Kan denna förekomst förklaras av att det finns en annan skola, den ekonomiska, som är det dominerande synsättet hos företag? Syftet med denna uppsats är att ställa den psykologiska skolans motivationsuppfattning emot den ekonomiska i en analys, och utifrån denna se om det går att dra slutsatsen att det ekonomiska tankesättet är det som dominerar och därmed ge en förklaring till varför belöningssystem förekommer som motivationsverktyg i ett företag. För att kunna utreda detta har vi valt att göra en fallstudie på företaget Tempur och dess säljare, samt tagit hjälp av teorier ur såväl den psykologiska motivationsuppfattningen, Maslow och Herzberg, som den ekonomiska, economic man.
Studie av värmeflöden i befintligt bostadsbestånd : Utvärdering av energieffektiva besparingsåtgärder
The purpose of this master thesis is to investigate different types of measures for making buildings more energy efficient and to estimate their profitability. The calculations were performed with the building simulation program VIP+ and the evaluation of the profitability with the life cycle cost method. Furthermore, it was examined how losses in the distribution of secondary systems of district heating can be avoided. Options to replace district heating with a local district heating system based on bio-energy have been investigated. The possibilities of achieving more efficient thermal energy consumption and production for the chosen estate were also examined.The object of the study has been a residential estate with 133 detached houses in Uppsala, built in 1974.
Faktorer som påverkar lönsamheten vid köp av skogsfastigheter i Norrbotten
During the past 20 years, the price of forest estates in Sweden has raised more than the price of timber. The purpose of this study is to investigate if it, despite this development, is possible to buy a forest estate based on economic grounds. Different forest parameters will also be studied to analyse their effect on the profitability.
The study is done in cooperation with the company LRF Konsult. Purchase price of 34 forest estates near the coast of Norrbotten, Sweden, has been compared to yield valuation. For the valuation, guidelines from the Swedish author Lantmäteriet was used.
Lantbruk i framtiden : ett praktikfall
The economic prerequisite to many farmers in Sweden after the EU membership and the
new agriculture policy has generated large demands on the farm management. Until year
2004 you got a grant based on what you had produced and not on consumer demand. In
2005 a new economic aid (Mid Term Revue) was introduced and the conditions has
changed again. Due to this I have chosen to do a cost-benefit analysis on a case, to
investigate if the present production is sustainable in the future.
My conclusion is that the profitability is acceptable even if the farm has a high debt. But
to make the production more profitable the products produced should be refined as much
as possible at the farm, to get maximum economic return.

Skyltfönster som kommunikationsverktyg- En kvantitativ studie om kreativa och mindre kreativa skyltfönsters effekter
This research examines the effects of creative store window displays of fashion brands in enhancing recall, attitudes, intentions and brand associations. A comparison has been made between high-end and low-end brands, creative versus non creative store window displays to identify differences in effects. The theory applied in this study has been used from creative advertising effects due to the lack of relevant research in store window display effects. Therefore this study is a contribution to the research of store window effects. The method used in this study compare fashion high-end brand with fashion low-end brand by placing the products in the store window display where the creativity has been manipulated.
Joker och forumspelspedagog : yrkestillvaro i variation
By means of text creation I approach, reflect upon and try a number of aspects of my own professional existence as a joker in forum theatre and as a forum play pedagogue.This essay is structured like the days of a week and it specifically relates three problematic situations: first, a Monday containing a case of discrimination during the performance, then, a glimpse from a Wednesday when I failed to use the time with enough consideration of our common work and, finally, a Thursday when I was professionally questioned.These three situations are described thoroughly and then they are tried by me. This is carried out partly by reasoning, partly by using for example sociological, pedagogical and above all philosophical texts in order to widen my understanding of my existence as joker and forum play pedagogue. When writing this essay I really realized the importance of taking the reactions of the spec-tators into consideration. I have had the opportunity to develop thoughts about the way in which reflection is created and thoughts about different layers of reflection. I have also pondered over the way in which I distinguish between forum play and therapy as a forum play pedagogue.

Från ansökarland till medlemsstat. -En studie av Polens förhandlingsprestation under EU-utvidgningsförhandlingarna
In May 2004 the European Union enlarged from 15 to 25 member states and it was the biggest enlargement since the foundation. Two years earlier Poland, as one of the new member states, finished four years of accession negotiations with the EU.This study focus on the case of Poland and how the accession negotiations with EU were conducted. According to the theoretical framework of asymmetric negotiations Poland was said to be a weak party and the EU was considered a strong party in the enlargement negotiations.The aim of the thesis is to examine Poland's negotiation performance and determine what Polish failure and success in the accession negotiations depends on. The research contains a illustration of the motives for enlargement, the negotiation process and structure, attitudes and behaviour and finally results of negotiations in specific areas.The study concludes that Poland's negotiation performance was influenced by the Polish negotiation team's unpleasant attitude, confused organizational structure, lack of coalition partners and the strong will to become a member state, in both positive and negative ways. Finally, Poland was most successful in negotiations that concerned specific issues which were of great importance for Poland but less prioritized by the EU..
Effektiv lagerstyrning genom tillförlitlig prognostisering : Effective inventory control through reliable forecasting
This study was done regarding whether sealing or ventilation is the best solution to prevent moisture on cold attics. The authors of this report addressed the problem with moisture in attics when they started their cooperation with Peab.The methods included interviews with people, database research, and calculations of a project in Akersberga north of Stockholm. The conclusion is based on interviews and other information as they are analyzed in relation to the house of reference. The focus of this report is on problems with moisture in the attics known as cold attics.The background of the problem with moisture is that today?s slabs are usually insulated to save energy and that the attics nearly gives the climate as the outdoor climate.
