Utvecklingen av magnetkameran har under de senaste 20 åren gått stadigt framåt. Genom att styrkan på magneterna stigit har även riskerna med ferromagnetiska implantat ökat. Ett flertal incidenter har rapporterats, de flesta från USA, men även ett fåtal ifrån Sverige. Incidenterna har orsakats av misstag, exempelvis då felaktighet eller otillräcklig information rörande patienten tillhandahållits. Den här studien ska visa på hur farligt magnetfältet kan vara om man inte är försiktig och alla rutiner inte följs noggrant.

Bakgrund: De flesta svenskarna sparar i form av värdepapper för att investera sina pengar och få en avkastning. Vilket placeringsalternativ ska de välja mellan investering i traditionella eller speciella fonder? De traditionella fonderna har en relativ avkastning och en stor risk, medan de speciella eller hedgefonderna har en lägre risk och en absolut positiv avkastning oavsett marknadsläge.I denna studie kommer att undersökas om hedgefonders avkastningsmönster är trovärdig, och om deras målsättning har uppnåtts under åtta års period.Syfte: Syftet med denna studie är att undersöka om det finns ett samband mellan olika svenska hedgefonders investeringsstrategier och avkastningsmönster samt undersöka hur dessa hedgefonder skiljer sig från de traditionella fonderna och marknadsindexet. Delsyftet är att studera två olika perioder och urskilja hur fonderna presterar under hög respektive låg konjunktur läge.Metod: Studien är baserad på forskningsstrategin kvantitativa metoden. Sekundär data i form av historiska avkastningssiffror för åttaårsperiod är avhämtad.

The purpose of this thesis is to bring insight into and understanding of how the market for emission rights in Europe currently works and what problems it is currently facing. The research can be said to be based on positive theory, in the sense that it is grounded more on empirical theory on the subject than normative theory. Furthermore, a qualitative approach to generating data has been used. This has led to a pattern mode of explanation, where understanding a unique and complex field is the focus. The theoretical perspective utilized in this thesis is mainly based on empirical research on similar market-based systems for emission control.

A reforming trend is captured showing that countries are shifting from defined benefit pension systems towards defined contribution systems. The reforms have been justified through predictions that the defined benefit systems will not manage to provide good enough pensions to members in the future. The newer defined contribution pension plans often include individual financial accounts where individuals have the possibility to choose how a part of their pension savings should be invested. Sweden was early to introduce such a system, which at the moment provides more than 800 funds to choose from. The aim of this thesis is to capture the market risk associated with these individual investments and does so by using Monte Carlo simulations for six selected pension funds.

Syftet med denna studie var att undersöka risken för Compassion Fatique hos sjuksköterskor vid Akademiska sjukhuset i Uppsala. Compassion Fatigue är då en person som konsekvens av sitt empatiska engagemang gentemot en annan person blir emotionellt utmattad. En enkätstudie bland psykiatrisjuksköterskor och sjuksköterskor inom den somatiska vården gjordes, dessa jämfördes i avseende på Compassion Fatique-risk. Huvudresultatet tyder på att nästan en fjärdedel av sjuksköterskorna som grupp är i riskzonen för att utveckla Compassion Fatique och att närmare 40 % av alla deltagare var i riskzonen för att utveckla utbrändhet. 21,9 % låg under referensvärdet för Compassion Satisfaction, vilket innebär att man ej känner sig tillfredställd med sin arbetssituation.

Background: Today, the environment of a company is characterized by quick changes like leaps of technology and market shifts. The problem is how this turbulent environment and an uncertain future affect how a company creates strategies and how its structure is adapted. Can a certain choice of strategies or a certain structure be a way of dealing with an changing environment? Purpose: The purpose of this thesis is to explore if and how Banverket Telenät, as an example of a company in a turbulent business like the Swedish telecom industry, tries to deal with an uncertain future through strategy and structure. Procedure: We have carried through a qualitative case study with interviews and gathering of additional information concerning the business.

The aim of this Master?s thesis is to examine and understand how teachers of younger children view the concept of critical evaluation of information and how their interpretations of the concept relate to their teaching. The need for the development of children?s ability to critically evaluate has been emphasized through research as well as the need for collaboration between teachers and librarians in order to help pupil?s process information into knowledgeThe study has a socio-cultural perspective and the material was collected through observations and qualitative interviews with teachers. The results of the study indicate that many teachers experience uncertainty when it comes to the area of critical evaluation and that they do not teach the subject to any substantial extent.

Banks carry a great responsibility when it comes to the financial systems in our society. Disturbance in the credit system affects both lender and borrower. All financial institutions must therefore carefully estimate their risk exposure. This assessment enables them to cover themselves from losses with appropriate capital buffers as main guardian. In order to prevent bank crises and also to maintain financial stability in general, new regulations concerning analysis and preventive actions were introduced on the 1st of February 2007.

This essay analyses two swedish magazines about marriage, called "giftermålstidningar", from 1914 and 1924. With ideology as theoretical basis the subject matter is to find words and expressions of ideological influence in the source material. These influences is assumed to come from contemporary marriage laws, which expressed certain views about heterosexual relationships. In addition to the state's laws, the writers in the magazines is presumed to be influenced by other contemporary ideas. Either an older, christian tradition from brittish baptist Frederick Brotherton Meyer, or the swedish economist Knut Wicksell, who represents the Neo-Malthusian world view.

This thesis is divided in to two different parts. The first part includes examination of the measurementsystem of an industrial robot using a resolver sensor. The main focus is on methods for suppressing noise in the angularvelocity signal without increasing timedelay. Five different methods are investigated. Three of these are based on oversampling: burstsamplingmethod, meanvaluemethod and correlationmethod.

Background: The business market today is characterized by tough competition amongst the competitors to capture consumers? interest and money. One marketing tool companies can use to achieve this is the company?s image. The customer buys not only a product, but also the image that the company or the product is associated with.

In a business environment where the stakeholder perspective is evolving and sustainable development is receiving increased attention, it is of importance for companies to adjust. The demand and pressure is exerted from several stakeholders who force companies to take action and live up to the expectations because if failing to do so, negative consequences will most likely be the case. The attention of this study is on ABB Power Products (ABB PP) and their environment and working environment risk management. The aim of this thesis is to identify and describe how perceived environmental risks are managed and what the incentives are to work proactively to minimize the risks. The incentives for a proactive risk management strategy are researched through both a strategic and operational perspective.

Trenden är att det ställs högre krav på börsnoterade bolag att redovisa mer omfattande extern bolagsinformation genom årsredovisningen. En del av informationen behandlar bolagens exponering och hantering av risker, ett område som fått större utrymme med åren eftersom riskredovisningen har stor betydelse för bolag som såväl användare. Syftet med studien är att skapa förståelse för hur börsnoterade bolag genom extern redovisning av risk kan eftersträva minskad informationsasymmetri och ökad legitimitet omkring en ekonomisk turbulent tidsperiod. För att adressera studiens syfte har en longitudinell flerfallsstudie i svenska börsnoterade skogs- och tillverkningsbolag genomförts mellan åren 2006-2012. Ett aktörssynsätt antogs där bolagens årsredovisning analyserades genom diskurs- och innehållsanalys.

AbstractTidigare studier har visat att fritidsgårdsbesökare löper ökad risk att utveckla antisociala beteenden, genom att börja använda tobak, alkohol och droger. Föreliggande syfte med undersökningen var att ta reda på om de kommunalt drivna fritidsgårdarna i Sandviken innebär risk eller skydd för unga besökare, vad gäller användning av tobak, alkohol och droger; samt att undersöka könsskillnader gällande bruk av dessa substanser, skillnader mellan tobaksbrukande och icke tobaksbrukande ungdomar vad gäller alkoholkonsumtion samt undersöka vilken inverkan föräldrars tobaksbruk har på ungas tobaks-, alkohol- och drogvanor. En enkätundersökning gjordes bland 163 ungdomar i årskurs 8. I denna framkom att fritidsgårdsbesökare snusar i högre utsträckning än icke besökare. I övrigt fanns inget som tyder på att fritidsgårdsbesökare skulle röka, dricka alkohol eller använda droger i högre grad än icke besökare.

BACKGROUND Until 1988, it was forbidden to neuter male dogs in Sweden without a veterinary medical cause, so there is clearly no long tradition of this procedure in healthy dogs. According to the website of The Swedish Kennel Club (SKK), February 11, 2011, there has been an increase of castrated male dogs in Sweden. They see this increase as worrying, especially in cases of the less common breeds, where it is most important to maintain the gene pool. The SKK expresses concern that castration is used as a tool to influence the personality of dogs, instead of training and education of the dog. They write that castration should be preceded by a discussion initiated by the veterinarian, where the pros and cons of castration are weighed against each other.
