Risken för kolorektal cancer i förhållande till kostmönster, fysisk aktivitet och BMI i sydöstra Sverige : Analys av data från en fall-kontrollstudie

Bakgrund: Tidigare studier har identifierat flera riskfaktorer, såsom kost, fysisk aktivitet och BMI, gällande kolorektal cancer. Att analysera kost utifrån kostmönster istället för enskilda livsmedel har visat sig vara effektivt för att undersöka risker för kolorektal cancer. Datamaterial samlades in med hjälp av en fall-kontroll studie med 257 fall och 805 kontroller.Syfte: Identifiera faktorer som ger en höjd eller sänkt risk för kolorektal cancer utifrån områdena kost, fysisk aktivitet och BMI.Metod: Faktoranalys användes för att upptäcka kostmönster. Logistisk regression användes för att skatta oddskvoter och 95 % konfidensintervall.Resultat: Tio stycken kostmönster erhölls från faktoranalysen. Kostmönstren ?Läsk, juice och mjölkprodukter? (OR=1,288; ORQ4=2,159), ?Te, men inte kaffe?(OR=1,228; ORQ3=1,891; ORQ4=1,668) och ?Fågel, rött kött och fisk?( ORQ4=1,724) gav alla en ökad risk.

Drama som ett pedagogiskt verktyg i värdegrundsarbete

A pupil with ADHD is constantly getting new impulses and is unable to focus and remain concentration on their task at school. When the pupil loses concentration he or she can often be loud and thereby disturbing all the other pupils in the classroom. One of the reasons for losing their concentration is that these pupils got poor working memory. A recently study shows that working memory can be improved by playing and practice music.A theory that all people have a multiple intelligence that emerges from learning is a part of this study because school should encourage all children and ensure their individual learning. Multiple intelligences means that each person learns in different ways, for example through the musical intelligence that this essay partly focuses on.

Värdedrivare i buyout-investeringar av noterade private equity-bolag - En empirisk studie av 15 svenska buyout-investeringar 1998-2012

Sweden is a world leader in listed private equity and ranked fifth in the world in market capitalization. The sector is attracting increasing interest from the investment community. However, the private equity industry in Sweden has historically poor reputation and is criticized for creating value through high leverage, multiple riding and severe cuts. This study analyzes value creation drivers in buyouts from the perspective of the private equity firm using a dataset of 15 realized buyouts by private equity firms listed on NASDAQ OMX Nordic Stockholm. The methodology used separates the value contribution of leverage on the private equity firm's return from internal operational improvements and external variations in transaction multiples.

Blodtrycksfall, pulstryck och lindriga kognitiva symptom - En polytom logistisk regressionsanalys

People live longer. There is a growing need to increase the knowledge of aging and of the need among the elderly for medical care in the near future. As a step towards meeting this need, a survey among the elderly in Skåne is made by the division of Geriatric Medicine in Malmö University Hospital. This survey is called Gott åldrande i Skåne, GÅS. A frequent decease among the elderly is Mild Cognitive Impairment (MCI).

Hur viktig är statens styrka för ekonomiskt välstånd?- En studie av alla världens länder

What role does the state play in economic development? This thesis seeks to investigate the relationship between a strong state and economic development. To define the concept of a strong state I focus on the relationship between the scope of state functions and the efficiency of which these functions are implemented. The concept of a strong state is in this thesis defined as the efficiency of the state functions. By using a database constructed by three economists; David Kaufman, Aart Kraay and Massimo Mastruzzi as a measurement of a strong state I test the relationship with economic development empirically.

Interacting with EDIT. A Qualitative Study on, and a Re-design of, an Educational Technology System

This thesis aimed to study the interaction between an educational technology system and its users and give suggestions for design improvements. The technology system is called EDIT (Educational Development through Information Technology) and has been developed and applied at Linköping University?s Faculty of Health Science. EDIT supports Problem Based Learning and enables scenarios to be presented through the World Wide Web. The study was divided into two parts.

Konst som investering: En studie av investeringar i svenska kvalitetsmålningar under perioden 1985-2006

This paper analyses how Swedish fine-art oil paintings sold at auctions has performed as a monetary investment during the period autumn 1985 until spring 2006. An average price technique as well as a hedonic regression technique, applied to a sample of 19 213 auction sales, is used to construct price indices. The indices show somewhat different results, which is explained by the inability of the average price model to adjust for relative differences in quality between periods. The hedonic regression model on the other hand captures this effect, why the hedonic index is applied in a financial return model. By adjusting for transaction cost, the financial return of an average investment in paintings is calculated.

Är rika områden friskare än fattiga? : en studie av sambandet mellan ett områdes ekonomiska nivå och dess invånares hälsa

En jämlikt fördelad hälsa är ett mål för den svenska folkhälsopolitiken, och därför är det viktigt att studera de sociala och ekonomiska faktorer som påverkar hälsan. Den här uppsatsen undersöker om det går att fastställa ett samband mellan medelinkomst och allmän hälsonivå i Sveriges församlingar. Tidigare studier visar att hälsan påverkas negativt av att leva under sämre ekonomiska förhållanden. Jag använder data från Socialstyrelsens patientregister från slutenvården samt IFAU-databasen och genomför en regression med hjälp av en fix effekt modell som rensar för områdesspecifika fixa effekter. Resultaten visar på ett negativt signifikant samband mellan medelinkomst och antalet inläggningar per capita i församlingarna.

Faktorer som påverkar kapitalstrukturen ? En studie utifrån den svenska industribranschen

Syfte:Huvudsyftet med vår uppsats var att testa om ett antal utvalda oberoende variabler påverkar skuldsättningsgraden i svenska börsnoterade industriföretag från 2003 till 2007. Detta utförde vi med hjälp av ett antal utvalda teorier och modeller. Vidare använde vi oss av respektive företags årsredovisningar. Metod:Variablerna undersöktes i två olika steg. Först genomfördes en enkel regression för respektive variabel, detta för att undersöka om ett samband mellan varje förklarande variabel och den beroende variabeln skuldsättningsgraden kunde säkerställas statistiskt.

Revisionsutskott i svenska aktiebolag: En statistisk analys

The recent development in several countries? legislation and best practice recommendations in relation to corporate governance in general and audit committees in particular have affected Swedish listed corporations in the form of the Swedish Corporate Governance Code and the coming EU-directive. This paper aims to discover what factors affected Swedish listed companies to form audit committees when this was entirely voluntary. We collected data from the annual reports of 121 Swedish listed companies and formed eleven hypotheses as to what factors we believed affected the voluntary formation of audit committees based on Agency Theory, economies of scale and circumstances specific to the Swedish environment. We then analyzed the data through the use of a multivariate logistic regression model.

DEN EUROPEISKA IDENTITETENS KOMPONENTER En kvantitativ analys p? vad som definierar den europeiska identiteten

The European identity plays an important role for the EU and especially within its will to further integrate its citizens, hence it is a way for individuals to not only identify with its nation, yet also with Europe. Previous research has already established that an individual can possess two territorial identities, such as a national and a European identity, above all it has established how the identities can equally interplay. Further it has been explained how territorial identities are composed of two aspects: civic and cultural. While the previous research has stated how the European identity possesses both aspects, though to varying degrees, little attention has been put to examine how individuals who possesses multiple territorial identification, defines its European identity. This study therefore aims to study which aspects, civic or cultural, individuals with a citizenship who possess multiple territorial identification, assign their European identity.

Vaccinering mot H1N1 : En studie av vad som påverkade svenska individers vaccinationsbeslut 2009

The Swine flu (H1N1) erupted in 2009 and wasquickly spread over the world and developed into a pandemic, with a great threat against people?s health. It was soon discovered that the H1N1?virus had a different character than the seasonal flu, since it especially affected younger individuals and the consequences from the disease were expected to be more severe. In Sweden it was decided to provide a free of charge vaccination against the H1N1-virus, and the Swedish vaccination ratiobecome relatively high compared to other countries.

Genom statistisk analys utvärdera geometriska parametrars påverkan på ett XPI- cylinderhuvuds snurrtal

This Master Thesis is a product development project that has been carried out in cooperation with Scania CV AB. The purpose has been to find the relationship between geometric parameters and the swirl number for an XPI- cylinder head in order to improve the design specification.The increased focus on environmental issues from society leads to tighter emission legislations for the truck manufactures. In order to drive the development forward considerable resources are spent on research and development on diesel engines and its combustion process. The inlet air has a significant impact on the formation of emissions and the flow that is desired is called swirl. Swirl is achieved by making the air rotate around the vertical axis of the cylinder.Earlier cylinder heads that has been developed at Scania CV AB have shown clear relationships between geometric parameters of the cylinder head and the swirl number.
