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.

This essay analyzes the market for entertainment software by identifying and explain the products typical properties, in addition i clarifies the behavior of consumers and producers. One of the most important property related to software is the ease with which it can be reproduced. When such reproduction is done illicit it´s called piracy. The software industry often claims that piracy leads to big losses for the companies as well as in welfare, the essay clarifies that this doesn´t has to be the case. On the contrary the possibility to cheap production and distribution may lead to an increased welfare.

This paper studies the option market?s implied dividend as a predictor of future equity market returns. We introduce this variable in the simple total return framework and discuss some complications of using it as a proxy for the expected dividend. We construct some regressions using the price-dividend ratio and the implied dividend growth, and test them on six years worth of data on the EURO STOXX 50-index. The main result is that implied dividend growth exhibits some forecastability over two-year horizons, but that the dataset is too short to draw any definitive conclusions about long-horizon forecastability.

The use of Internet by children and teenagers has become a special field of interest. Certain risks are associated with young peoples use of this media and national and international measures have been taken to assess and counter these risks.Library and informationscience have approached the subject of risks by looking at different software´s, so called Internet filters, that is used to control and censor the access to Internet based resources. In the USA, where public services and institutions that provide Internet resources to children and youth have started to require censorship of the Internet, a debate has arisen concerning the use of so called Internet filters.The theoretical basis of this master´s thesis is related to the conception of risk, gender and childhood. The focus of the paper lies on young peoples use of information and communication technology (ICT) and how risks associated with young peoples use of the Internet is constructed by different parties involved in supplying Internet resources. By means of a case study at a primary school in Skåne and at the company Netscan in Malmö.

The real estate industry is a sector where the companies generally have a capital structure which is high leveraged. The financing? with the related terms ? is therefore specifically of high importance for the companies in the sector. Traditionally, the way of obtain financing is by borrowing from the bank. Lately, due to new bank regulations, the banks have become more restrictive in their lending which have lead to a growth of other financing alternatives.

This master thesis has been performed at Vattenfall Power Consultant in Gothenburg and Trollhättan for Vattenfall Vattenkraft. In this report vacuum circuit breaker in small-scale hydropower stations with the rated power 4 MVA and below has been studied. Models of the stations are modeled and analyzed in PSCAD/EMTDC to study the high voltage transients that are created after current chopping with vacuum circuit breaker. Vacuum circuit breaker may chop the current before it reaches zero value, which means that high voltage transients can be created. The equipment of the stations can be destroyed by high voltage transients.The purpose of this thesis is to examine the use of vacuum circuit breaker in small-scale hydropower stations and the risk for high voltage transients from current chopping.According to the results there is a risk of high voltage transients after current chopping with small synchronous generators in stations with the operating voltages 0.4 kV and 3.6 kV.

Denna kvalitativ intervjustudie, söker en förståelse kring fenomenet sex som självskadebeteende. Självskadebeteende har studerats och definierats, men sex som ett självskadebeteende är inte inkluderat som ett begrepp i dessa vetenskapliga studier (Zetterqvist, 2014; Nock, 2014; Klonsky 2009). Däremot har psykologer, organisationer och andra professionella tolkat och definierat fenomenet som att det existerar (Sjöström, 2012; Landgren 2015; Jonsson och Mattson, 2013; Tjejouren 2015; MUCF, 2013). Genom intervjuer med tre olika personer som kommer i kontakt med sex som självskadebeteende, kombinerat med tidigare forskning, visar denna studie att sex kan användas som självskadebeteende och att det görs i syfte att hantera (coping) ångest och andra negativa känslor. Tidigare trauman och/eller en dysfunktionell familjedynamik kan leda till att en individ utvecklar icke fungerande strategier för att hantera potentiella dåliga känslor. Individerna vänder sig till sexuella destruktiva beteenden som en affektregleringstrategi.

In this study the aim is to examine how employees in treatment programmes relate to girls that self-harm. To achieve this four questions were formulated: (1) What experiences does the empolyees have of meeting girls that self-harm? (2) Based on the employees? experiences, what has been the background to why the girls self-harm? (3) Based on the employees? experience, what increases or decreases the risk of self-harm? (4) How do the employees? work with girls that self-harm? The method being used was qualitative interviews with vignettes. The theoretical framework is Becker?s Labeling Theory and Bronfenbrenner?s Ecology of Human Development.

Konsumentbeteende handlar om när, varför, hur och var människor gör ett inköp av en vissprodukt. Konsumenternas demografiska profiler är ett viktigt område inomkonsumentbeteende. När det kommer till frågan om shopping så förknippas ordet i stort settmed kvinnor. Samtidigt beskrivs ofta manligt konsumentbeteende från ett traditionelltperspektiv och skiljer sig från det kvinnliga köpbeteendet. De traditionella stereotyperna förmanligt konsumentbeteende är att män är mer benägna att ta risker när de handlar eftersom deinte brukar fråga personalen om hjälp eller åsikt, de jämför inte olika alternativ med varandra,de brukar inte planerar sina inköp, de är inte villiga att handla i grupp och är ?rädda? för atthandla i kvinnliga butiker.Eftersom könsrollerna kan ändras över tid är det viktigt att inom marknadsföring undersökakring dessa ämnen och inte ta de stereotypa könsrollerna förgivet.

Syfte: Studiens syfte var att beskriva kvinnans upplevelse av sin livsvärld, vid risk för att utveckla ärftlig bröstcancer. Metod: Studien genomfördes genom en systematisk litteraturstudie, med inriktning på kvalitativa artiklar.

The study was performed based on a qualitative method using a hermeneutical approach used to interpret the semi-structured interviews. The study aimed to investigate the Multisystemic therapy (MST) team in Halmstad municipality perceptions on the treatment method multisystemic therapy for youths from the ages of 12-18 years old.The questions were: Does the MST therapists experience that the MST is a method that leads to an improved situation for young people who receive the method? What do the MST therapists describe as opportunities and obstacles in the work with the method?The study builds on previous research on MST and empowerment based on MST. The study shows three therapists and an MST leader's experiences of the treatment and how it is aimed at influencing the parents and the youth for a change. From therapists statements it highlights how the MST method is designed for the young people?s motivation to change by means of the internal and external networks.

The aim of this paper is to examine venture capital in football player contracts in Sweden. This is a phenomena that have existed in Sweden since 1999 when the company Djurgården fotboll AB was founded, since then eight other companies have been started. These companies form an alliance with a football club and invest in player contracts. These contracts have high risk since it is valued by the performance of the contracted player. The venture capital firms have no formal control over their investments and they are showing negative results.

This thesis compares different methods for risk assessment of a creosote contaminated site in Vansbro, Dalarna. In a complementary study the importance of using representative data for calibration and validation of stationary groundwater models is discussed. The time dependency between surface water levels and groundwater levels on the site in Vansbro is evaluated by step response analysis. The results show that the groundwater levels reflect only long-term variation in the surface water levels. Hence the use of such long-term means for calibration and validation of the stationary groundwater models is the only theoretically defendable alternative.As a first step in the comparison of risk assessment methods the degree of contamination is evaluated on the basis of generic guideline values for contaminated soils, developed by the Swedish Environmental Protection Agency.

Rapporten är skriven för att dokumentera den befintliga installationen av ballast-, läns- och brandsystem ombord på fartyget M/S Calmare Nyckel. I enlighet med uppdragets specifika-tioner kommer även förslag på förbättringar att presenteras. Förslagen bygger till största del på fakta från en leverantör av ventilkomponenter och av klassen ställda krav på installationen. Förbättringarna beaktar i huvudsak minskade risker och ökad säkerhet. De största skillnaderna med de nya förslagen är att länsvattensystemet skiljs från de övriga systemen, de viktigaste funktionerna fjärrstyrs med hjälp av pneumatik och systemets komponenter märks enligt branchstandard..
