Aktivt ägande och lönsamhet i svenska företag
Active ownership is widely regarded as positive for the development and performance of businesses. In this paper, we investigate the impact of ownership concentration and owner identity on return on equity (ROE) in Swedish companies between 1986 and 2008, and show that active ownership might suffer from opposing effects. We find evidence, albeit weak, that ownership concentration has a positive effect on profitability, but that it levels off at high levels of ownership shares. Furthermore, we propose that family ownership has a negative effect on profitability. Our results are dependent of choice of statistical method, but show nonetheless a need to reevaluate what seems to be a universally positive view of active ownership..
Aktiva ägares påverkan på svenska börsbolags lönsamhet
This thesis investigates the effects of active ownership on the return on assets (ROA) of Swedish listed companies during the years 2003 to 2013. Active ownership is operationalized based on the probabilistic voting model that is used to calculate the minimum amount of shares the largest shareholder needs in order to possess control of a contested vote at the shareholder meeting. We study the three largest lists on the Nasdaq OMX Stockholm, having 1454 observations from 207 companies to test our hypothesis. The main result from the study is that there's a significant positive relationship between active ownership and ROA during the investigated period. The active owners' relative strength also proves to have a significant positive relationship to ROA..
Terminallokalisering med tyngdpunktsberäkning och kostnadsanalys
The Kedertruss is the loadbearing part in the Keder weatherprotectionsystem and it has been analyzed concerning its loadbearing capacity. The Kedertruss is produced and manufactured by Wilhelm Layher GmbH & Co. KG and this report has been made for their Swedish division Layher AB. The Kedertruss, designed in Germany according to German designcode, has been recalculated concerning Swedish conditions according to Eurocodes and a ongoing European standardization project. The two-dimensional program Winstatik Frame Analysis has been used for evaluation of load effects. Capacity has been calculated by hand-calculations and it has been verified that the Kedertruss in its larger spans isn?t able to withstand the loads.
Kan selen skydda mot utveckling av diabetes mellitus typ 2 En systematisk översiktsartikel.
Bakgrund: I dag har 220 miljoner människor diabetes världen över och 90 % av dessa har typ 2 diabetes. Sjukdomen föregås alltid av en insulinresistens och eftersom den har en koppling till oxidativ stress är en teori att spårämnet selen kan spela en viktig roll. Det är känt att selen har antioxidativa effekter i kroppen och tidigare djurstudier har visat att selen skulle kunna härma insulinets effekter samt öka insulinkänsligheten.Syfte: Att ta reda på om selen kan skydda mot utvecklingen av typ 2 diabetes. De frågeställningar som användes var om selensupplementering, selenintag via kosten eller selenstatus i blod kan påverka risken att utveckla typ 2 diabetes hos friska individer.Sökväg: Datainsamlingen genomfördes i den medicinska databasen PubMed med sökorden ?selenium AND diabetes mellitus type 2?.
Förändring av styrning inom en offentlig stödverksamhet: En studie över hur styrningen förändras inom en offentlig serviceenhet påverkas av en privatisering
The purpose of this study is to perform an in-depth analysis of what effects a privatization of a service organization has on the management control system within the organization. The paper studies a service organization which provides service for the county council in Östergötland, Sweden. The result is based on interviews with several people, both within the acquiring private company and also within the county council in Östergötland, and analyzed using Samuelson?s (2005) framework from his study ?Organizational, Governance and Control ?. The major finding in the thesis is that the factors that have had the largest impact on the changes in management control are the new owner demands and the degree of operationalization of the overall goal..
Cypern, EU:s halva medlemsstat
Since the 1st of May 2004 Cyprus is part of the European Union. The Republic of Cyprus as a whole is part of the Union, but all of the advantages of the Union membership cannot be enjoyed in all parts of the country. Since December 1963 the Cypriot administration has been separated into two, a Greek Cypriot and a Turkish Cypriot, and since 1974 the country is also territorially divided. The Greek Cypriot political administration is considered to be the legitimate representative of the Republic of Cyprus, the Turkish Cypriot administration is only recognised by Turkey. Since the disruption of the country in 1963 the UN has been trying to get the Cypriot parties to agree upon a peace solution in order to reunite the country.
Om du säger det så
This study explores the different effects on attitude and behaviour three frequently used advertising techniques have. The techniques compared are social influence and egoistic and altruistic benefit-appeals. The results showed that ads featuring social influence had statistically significant higher mean values regarding attitude towards the ad compared to both the other ads, and significantly higher mean values regarding brand attitude compared to the ad appealing to egoistic motivations. Though, all advertising effectiveness measures used in this study - that is, attitude and intention variables - indicated that social influence was more effective than the other advertising messages. Thus, in accord with earlier studies, it can be stated with confidence that social influence is an effective tool to use in marketing communications..
Vattenkvalitet och risker vid ändrat intag för vattenförsörjning i Västerås
Water is the most essential resource for life. In cases where drinking water is processed from surface water it is important to ensure the raw water is of good quality, and is suitable for processing through the water treatment plant.The drinking water for Västerås is sourced from Västeråsfjärden, in the western side of Lake Mälaren. The city itself is home to marinas, ports, a wastewater treatment plant, the Svartån outlet, sewage pumping stations and stormwater outlets. Because of the negative effects these activities have on surface water quality, Mälarenergi AB is interested in relocating the raw water intake point to Granfjärden, 10 km east of Västeråsfjärden. At Granfjärden the intake point would be less exposed to the activities in Västerås, and could be placed at a greater depth, resulting in better water quality.In this Master?s thesis the water quality and the pollution risks at Västeråsfjärden and Granfjärden sites are compared.
En enkel förbättring av stränder inom Visual Effects
Om man vill skapa ett realistiskt hav inom Computer Graphics är det viktigt att man har snygga övergångar till andra material. Ett exempel på detta är stränder och det är precis där fokusen på den här studien har legat. Studien gick ut på att hitta en enklare lösning på att visuellt förbättra stränder inom Computer Graphics. För att göra detta så testade två olika metoder i olika experiment. Den ena tekniken som testades var att simulera partiklar för att få fram en bättre strandlinje och de andra var att skapa en shader för att förbättra den.
"Say yes to yes" : en diskursanalytisk studie om medborgarnas roll i EU
The starting point of this thesis is the debate surrounding the two referenda?s in France and the Netherlands in May and June 2005, regarding the proposal of a European constitution. The aim of this study is to analyse how democratic legitimacy and the role of the citizens portrays within the democratic discourse of the European Union. The empirical material is based upon both speeches from the European Commission and news articles from the French newspaper Libération and the Swedish newspaper Dagens Nyheter. Discourse analysis is used as a theoretical frame of reference combined with models of democracy.

Inverkan av Kiselhalten på Värmeutvidgningskoefficienten hos Aluminiumlegeringar
The purpose of this report is to document the experiments carried out, methods used and results gained during research into how the silicon content of an aluminium alloy affects the coefficient of thermal expansion (CTE).The goal of this paper is to better understand and to find a relation between silicon content and the coefficient of thermal expansion.Experiments were carried out using carefully prepared samples of Al Si alloys (0, 7, 10 and 20% Si content). Using these alloys, the CTE could be measured using a dilatometer.Comparative analysis carried out could map the effects of silicon content on the coefficient of thermal expansion and an equation was created. Using simple graphs and the rule of mixture method, the authors were able to build a simple tool for calculating the CTE of specific aluminum silicon alloys..
