Att försÀkra eller inte försÀkra - det Àr frÄgan : En studie av försÀkring ur ett aktieÀgarperspektiv
Bakgrund: Alla företag utsĂ€tts för risk och en bransch med mycket stor riskexponering Ă€r flygbolagsbranschen. Hur risken Ă€n hanteras innebĂ€r den alltid en kostnad och för att aktieĂ€garvĂ€rdet ska bli sĂ„ högt som möjligt gĂ€ller det att minimera denna kostnad. Vilka huvudsakliga risker försĂ€krar sig passagerarflygbolagen mot? Vilka Ă€r motiven till att de försĂ€krar sig? Ăr hanteringen av försĂ€kringsbara risker i överensstĂ€mmelse med ett aktieĂ€garperspektiv?Syfte: Syftet med denna uppsats Ă€r att utifrĂ„n finansiell teori analysera passagerarflygbolagens anvĂ€ndning av försĂ€kring som riskhanteringsmetod. Analysen sker utifrĂ„n ett aktieĂ€garperspektiv.Genomförande: Studien bygger pĂ„ intervjuer genomförda med försĂ€kringsansvarige pĂ„ fem olika flygbolag.
Fördjupad miljöriskbedömning av förorenade markekologiska system. : Integrering av kemisk, toxikologisk och ekologisk information.
AbstractThe research project Liberation, supported by the European Commission under the Environment and Sustainable Development Programme (Fifth RTD Framework Programme) aimed at developing a decision support system for ecological risk assessment of contaminated sites has proposed a tiered system including the triad method. This method integrates contaminant chemistry and bioavailability analyses with observed ecotoxicological effects in soil and groundwater. In this study the triad method was used to perform a risk characterization of a former surface treatment and metal industry, now used for the student union buildings of the MÀlardalen University in Eskilstuna, Sweden. On the site, high concentrations of copper, zinc and nickel have been detected in the soil in a preliminary investigation of contaminant levels with XRF. For performing the risk assessment of the site according to the triad method, contaminant bioavailability, soil metal concentrations and soil toxicity were determined and an ecological assessment was carried out on four selected soil samples (one reference soil and three samples with low (B), medium (C) and high (D) contaminant levels). Contaminant bioavailability was measured through leaching (ISO TC 190/S7) and biouptake tests (DGT).
Moderbolagets ansvar för dotterbolagets skulder : Avseende stödbrev och ansvarsgenombrott
Stödbrev utfÀrdas av ett moderbolag till en koncernextern part dÄ ett avtal skall slutas mellan stödbrevsutfÀrdarens dotterbolag och stödbrevsmottagaren. Uppsatsen redogör för hur stödbrev fungerar och dess uppbyggnad. Det undersöks ocksÄ vad det Àr för bakomliggande mekanism som förklarar hur avtal kommer till stÄnd och vilken betydelse det fÄr att gemensam partsvilja mellan utfÀrdare och mottagare inte finns om stödbrevets rÀttsliga innebörd. Eventuellt kan Grönfors modell om avtalsgrundande rÀttsfakta vara en förklaring pÄ avtalsverkningarna. Uppsatsen undersöker ocksÄ institutet ansvarsgenombrott.
Attitudes towards hedging by diversified and non-diversified farmers : a comparative qualitative study
Deregulation on the market for agricultural products leads to a more globalised market with increasing price fluctuations. This, in turn, places the farmer in positions influenced by new risks but also improved opportunities. The farmers are faced by uncertainty in terms of financial outcome. To be able to utilise these new market conditions it becomes increasingly important for farmers to continuously follow the price trend, and to develop strategies how to manage the risks exposed by a volatile market.
Farmers with different conditions perceive risk in different ways. Hence, their risk management behaviour will vary.
SocialtjÀnstens barnskyddsarbete En studie av socialsekreterares riskbedömningar avseende barn som utsÀtts för vÄld eller sexuella övergrepp i hemmet.
The overall aim was to examine how the public interest to protect children from violence and sexual abuse at home, is realized by social workers. The studyÂŽs central focus was the risk assessments as Social services are obliged to do when they receive a report containing concern that children are being exposed to violence or sexual abuse at home. The study addresses the following questions:o How do social workers go about practically, and what support and knowledge is being used to determine whether the Social services need to intervene for the protection of a child?o What risk and protective factors are taken into account by social workers in the assessment process?o What contextual factors do social workers experience are affecting them in the assessment process?o Which support does the documentation system BBIC provide in the assessment process?The study material was collected through qualitative group interviews, with a modified vignette methodology as tools. The study included a total of twelve social workers, with varying numbers in each interview group.
Hedgefonder : Hur kan dess risker och möjligheter förmedlas
We have in this essay studied the Swedish Hedge Fund Market available for the average Swedish private investor. We have closely looked at the risk measurements that are applicable on the evaluation of Hedge Funds today, and furthermore studied how they are communicated and what they actually contribute with in terms of risk and yield. Our survey attempts to clarify the shortcomings in the communication between the Hedge Fund Managers and their smaller investors. Do they really know where they put their money? The market is rapidly expanding and our goal was to find improved ways to inform about the Hedge Funds risks and opportunities.
Kan företag genom sin redovisningsinformation pÄverka volatiliteten i aktiekursen?: en studie av sambandet mellan informationskvalitet och risk
The purpose of this paper was to examine the potential presence of a relationship between the quality of corporate financial disclosure and the volatility in stock price in the Swedish market. This was carried out by investigating the hypothesis that an accurate annual report with high information quality results in a decrease in volatility. Previous studies have been done with this approach and in some cases the above stated hypothesis was found to be true. Thus, in the absence of a perfect efficient market the level of information quality may to some extent explain the volatility in stock price. However, the result of our study gave no evidence in support of this hypothesis.
Kapitalförvaltarnas arbetsmetodik vid förvaltandet av den diskretionÀra potföljen
Background: The devolopment in the exchange market has attract a large number of investors. The information flow is extensive and it might be hard to follow the dynamic market. Some investors therefore choose to place their capital in a stock portfolio which is manged by a professional firm with no influence from the capital owner, this management is called discretionary managing. Purpose: the purpose of the thesis is to examine the working methods and the rationality regarding the management of the discretionary portfolios. The purpose is also to try to examine whether there is a relation between the selected risk, return and fees.
En jÀmförande studie av fluiddynamiken för olika fluidiseringsmedium i en kallmodell av en 100 kW-anlÀggning för kemcyklisk förbrÀnning
To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.

Riskbedömningsmodeller. Kan anvÀndandet minska frekvensen av postoperativt illamÄende och krÀkning?
Inledning Postoperativt illamÄende och krÀkning Àr ett vÀlkÀnt problem efter sövning medgenerell anestesi och drabbar mellan 20 % och 30 % av alla patienter som blir sövda. För attminska de obehag och lidande som illamÄende och krÀkning kan ge den postoperativapatienten vore det optimala att profylaktiskt behandla de patienter som löper en stor risk attdrabbas av postoperativt illamÄende och krÀkning. För att avgöra hur hög risk patienten har attdrabbas av postoperativt illamÄende och krÀkning beskrivs i litteraturen ett flertalriskbedömningsmodeller som sjuksköterskan kan anvÀnda sig av. Syfte att granska omanvÀndandet av en riskbedömningsmodell kan minska frekvensen av postoperativt illamÄendeoch krÀkning hos patienter som erhÄllit generell anestesi. Metod Litteraturstudie.
PÄverkar BMI vÄrdinsatser vid risk för undernÀring?
SammanfattningDet har tidigare visats att överviktiga patienter riskerar att bli förbisedda i screening för undernÀring och att vÄrdpersonal har negativa uppfattningar om överviktiga individer. Det har Àven visats att överviktiga sjÀlva upplever att de behandlas sÀmre Àn andra. Men trots hög förekomst av undernÀring bland sjukhusvÄrdade patienter har fÄ studier utforskat om patienter med risk för undernÀring fÄr olika vÄrdinsatser beroende pÄ deras BMI. SÄledes Àr syftet med denna uppsats att undersöka om vÄrdinsatser vid identifierad risk för undernÀring i nÄgon utstrÀckning Àr beroende av patientens BMI.Datamaterialet kommer frÄn en retrospektiv tvÀrsnittsstudie baserad pÄ genomgÄng av 56 journaler för vuxna patienter med risk för undernÀring, inlagda pÄ somatisk vÄrdavdelning pÄ tre svenska sjukhus. Denna studie undersöker möjliga skillnader beroende pÄ patients BMI för förekomsten av 1) bedömning av mun och svÀljförmÄga, 2) kostregistrering, 3) dietistkonsultation, samt 4) kostanpassning.I detta begrÀnsade urval finns inga sÄdana skillnader som uppfyller kraven pÄ statistisk signifikans, men analysen pÄvisar nÄgra tendenser i datamaterialet som antyder att patienter kanske behandlas olika med avseende pÄ BMI.

Valet och kvalet kring kapitalstrukturen : om kognitionens inverkan pÄ finansieringspolitiken
Background: A company?s choice of capital structure is influenced by the access to internal and external capital but also by the opportunities and threats that the management perceives in the environment and the management?s attitude towards risk. How an individual perceives and interpret the environment depends on the cognitive structures, which are shaped by personality, background and earlier experiences. Accordingly cognitive structures can be expected to influence the choice of capital structure. Purpose: Out of a cognitive perspective we intend to study the relationship between the way a company views it?s environment and what capital structure it chooses to have, in order to contribute to an increased understanding about what lies behind a company?s capital structure policy.
Metabola syndromet kopplat till fysisk aktivitet och konditionsstatus
Abstract  The development and onset of diseases such as cardiovascular disease (CVD) and Type 2 diabetes are closely linked to genetics and lifestyle factors including physical activity and diet. A cluster of metabolic disorders called the metabolic syndrome (MetS) is a high-risk factor in developing these diseases. Acording to the International diabetes institute, one fourth of the worlds adult population has MetS. These individuals are twice as likely to die from CVDs compared to individuals without MetS. Physical activity (PA) and exercise has been shown to provide a number of positive effects that are considered to reduce the risk of developing sickness and premature mortality among both men and women of all ages, independent of other risk factors.
