Svenska hedgefonders investeringsstrategier och deras riskexponering
In this paper Swedish hedge funds and strategies are discussed and analysed. These new financial forms seem to draw recently a huge attention both in media, press and the academic world. The fact is that hedge funds have existed already for a long time but it is still known too little about them. After the introduction of hedge funds, different asset pricing models are discussed including the most basic of all ? CAPM and further Fama and French three factor model as well as the expanding model with conditioning approach.
Metod för dosoptimering av digitalt detektorsystem i klinisk drift
The county of Dalarna is at present carrying through a process of digitalization where traditional x-ray film is being replaced with digital detectors. Earlier used methods for dose optimization turned out not being sufficient. This report presents a method to harmonize dose levels between x- ray sites equipped with Fujifilm imaging plate systems. An exposure index, S, related to the dose level of the examination is computed to every x-ray image. S turned out to be inversely proportional to the detector dose used at the examination.
Akustiskt åtgärdsprojekt av en rockmusikklubb där live-musik spelas. Vad kan en audionom bidra med?
Introduction: The number of hearing impairments in Sweden is increasing. The largest increase is seen in ages 25-44. There are reasons to believe that these impairments are noise induced. Leisure time noise is not controlled in the same manner that industrial noise is. An ongoing conflict between city council officials and rock club owners, musicians and music event organizers about sound levels at smaller live music clubs exceeding the national sound level restrictions created the need for an acoustic intervention project.
Design och tillverkning av en stereoanläggning med aktivt delningsfilter
This thesis is the result of the author?s interest in music and electronics, namely the design and manufacturing of a stereo sound system with an active crossover. In short it can be stated that an active crossover has many advantages over its traditional passive counterpart. The active design naturally results in a more complex system comprised of a multiple number of components. This report deals with the theoretical aspects of preamplifiers, crossovers and power amplifiers as well as power supply and control.
Nationell identitet i konsten : Peter Johansson dekonstruerar mytbilden om svenskhet
The purpose of this examination is to identify how notions of Swedishness is created artistically, and from where these notions come. My method is to make a study on exhibition catalogues on the theme Swedishness/Nordism, with focus on the contemporary Swedish artist Peter Johansson. With a retrospect of his childhood in Dalecarlia, he investigates a Swedish iconography with it?s roots in national romanticism, which for more than one hundred years has been preserved and exploited of the tourist industry to market Sweden. It?s this monotonous iconography that Johansson deconstructs to make it appear like something else ? namely an iconography based on ethnic purity, which pushes away the foreign and protects the own.
Förbättrad förbränningsstabilitet i EBK för turbofläktmotor RM12 genom förändrad motorreglering : Improved afterburner combustion stability for turbofan engine RM12 by modified engine control
The engine of JAS 39 Gripen, RM12, has recently been equipped with a new flameholder and a new engine inlet. This change has caused an increased noise level from the engine when the afterburner is in use. The noise level reaches its peak when the afterburner is partially used. The problem is thought to be unstable combustion in the regions around the flameholder. A solution to the problem has been proposed by Volvo Aero.
Hot och våld i arbetslivet : - En kvalitativ studie om socialsekreterares utsatthet
The purpose of this study was to investigate how social services workers describe, the risk of being exposed to threats and violence in their profession. Six social services workers were interviewed, four from the Welfare Office in a major city and two from the Child and Family Services in a minor city. Results showed that the majority of social services workers consider themselves exposed in their profession, meaning that they feel there's a risk of a violent or threatening situation occurring in their work situation. All interviewees had experiences from some sort of threat or violence in a work related context and they attested that non-personal assaults, such as threats made through telephone, email and answering machines are more common than verbal assaults made in personal meetings. Being prepared and listening to ones intuition is a way of dealing with exposure when meeting with a client.
Marknadsföring av folkbibliotek i teori och praktik ? En studie av marknadsföringsarbetet på två folkbibliotek
The competition for people´s attention becomes harder and harder. If the libraries want to continue to attract visitors it´s important that their business is promoted. The purpose of this thesis is to in-vestigate how two public libraries work with marketing. The study is based on a marketing model, introduced by Philip Kotler and further developed by Eileen Elliott de Sáez. Kotler believes that marketing is a social process and that everything can be promoted.
"Prata högre! Jag hör inte vad du säger" : En kvalitativ studie om elevers och pedagogers upplevelser av Södertäljes nya skolmodell
"Speak up! I can?t hear you"This qualitative study is built on an investigation of a newly instated model that is used when building or renovating schools. The principles of the model are based on building schools with an open plan design where the walls are made of glass and the classrooms are not shut closed by walls, instead the classrooms are completely open except from screens that are used to indicate the ambit of the rooms. This model has been well debated and that is the reason why we chose to do this study.The purpose of this study is to find out how students and teachers experience this model. To do this we have done interviews and observations.
Miljögifters exponering, ackumulering och effekter på immunsystemet hos husdjur :
The purpose of this literature review was to describe the paths of exposure and accumulation of organic pollutants into the tissues of farm animals. Organic pollutants can be spread in the environment by air and rainwater. Farm animals can be exposed to these pollutants for example by eating soil or contaminated plants. Many of the pollutants can then accumulate in the fat tissues of the body because of their lipophilic character. Brominated flame retardants and perfluorolated compounds are both pollutants of current interest.
Återvinning av skönlitteratur - Återvinningsverktygens anpassning efter användares sökbeteenden : En fallstudie på Trelleborgs bibliotek
Traditionally the content of fiction has not been described, analyzed, classified and/or indexed to the same extent as non-fiction. As a consequence, this lack of content analysis has resulted in unsatisfactory fiction retrieval in relation to users seeking and search behaviour. This fact is why this Master s thesis is written. The total of library users' seeking and search behaviour is investigated in order to suggest methods to improve user adapted fiction retrieval tools. Suggesting relevant fiction retrieval tools corresponding to users' seeking/search behaviour is another aim of the study.
Feromoninnehållande substansers effekt på hjärtfrekvensen hos kvigor i östrus och diöstrus :
With increased milkproduction in our dairy cattle, comes a risk for a reduced fertility. Studies performed on animals and humans have shown that it is possible to manipulate the oestrous cycle through exposure to pheromones. This means that pheromones could potentionally be used to make reproduction more efficient. To evaluate the bioactivity of the substances in question, there is need for a bioassay. In insects, pheromones can induce a changed cardiac activity.
Faktorer som påverkar Vänerns öppna sandstränder och möjligheterna för hög biologisk mångfald ? med mossor som indikatorer på igenväxning
The sandy beaches of Vänern are threatened by overgrowth and thereby the biodiversity is at high risk to decline. This study is based on an inventory of vegetation of overgrowth character and mosses. The frequency and spread of mosses is perceived as an indication of initial or present overgrowth. External factors that have been taken into consideration are wind-, wave- and ice erosion, the slope of the beach, wear and grade of exposure. The purpose of the investigation is to control the beaches grade of overgrowth and find out which external factor is of most importance for the maintenance of the biotope. The results show that the beaches environment is affected by the slope of the beach, grade of exposure, size, wear and overgrowth.
Full goodwill method: Effekter av ändrade redovisningsprinciper för goodwill
The main aim of this paper is to consider the possible effects of a transition to a new accounting standard for goodwill. According to IASBs Exposure Draft of Proposed Amendments to IFRS 3 Business Combinations there is an inconsistency in the currently used purchased goodwill method. The full goodwill method is considered to be a superior alternative and is therefore suggested to become the standard from 2007. This paper comprises a quantitative study of the effects on certain key ratios for companies listed on the Stockholm Stock Exchange, arising due to the proposed transition. The period examined is 2004 and 2005.
VD:s incitament i form av rörliga ersättningar och dess påverkan på bolagets riskexponering: En empirisk studie av svenska bolag listade på Nasdaq OMX
The recent financial crisis has entailed in a fierce debate whether CEOs variable remuneration has caused unsound risk exposure in public companies. Hence it is considered as interesting to elucidate if this connection exists empirically. With grounding in principal-agent theory, and its implicit assumption of risk adverse agents, this study aims to find empirical evidence for a positively correlated relationship between CEOs variable remuneration and company risk exposure. Through a regression analysis of multidimensional data from 102 listed Swedish companies during the period of 2000-2009, we show that the relationship between CEOs variable remuneration and company risk, in contrast to our expectations, is significantly negative. The coherent result is interpreted as the inherent risk in companies seems to explain the usage of variable remuneration for CEO, rather than vice versa.
