Riskens förändring för svenska aktier och obligationer: 1919-2003

Purpose The purpose of our study was to investigate the changing nature of volatility during the last 80 years. Like in an American study, we tried to find some trends in the risk of stocks and bonds that would have an impact on the balance of a portfolio of stocks and bonds. At the same time we investigated the influence of inflation on the choice of portfolio. Methods We have used standard statistic tools and formulas to obtain our results. In most cases it was a matter of calculating average and standard deviation.

Fria, men ändå villiga? : En studie om företagsfaktorers påverkan på efterfrågan på frivillig revision

År 2010 avskaffades revisionsplikten för små bolag i Sverige vilket gör att det numera är frivilligt för dessa bolag att ha en revisor. Det är kombinationen av Sveriges låga gränsvärden för undantagande av revisionsplikt, samt avsaknaden på tidigare forskning i en svensk kontext som motiverar denna studie. I denna undersökning, som bygger på ett slumpmässigt urval av 400 svenska små bolag, testas faktorer som i utländska studier tidigare funnits påverka efterfrågan på frivillig revision. Detta görs för att se om samma samband finns i Sverige. Vi förutspår att efterfrågan på revision påverkas av företagets storlek, skuldsättningsgrad, risk och ålder.

Analys och kvantifiering av energieffektivisering inom fjärrvärmesektorn

The Swedish Government has set a target to reduce energy consumption through energy efficiency within the construction and real estate sector. The purpose of the study is to examine how energy efficiency within this sector could affect the district heating volume in the future, on basis of Vattenfalls district heating system in Uppsala.An Excel model has been created to study how energy effficiency measures affects district heating demand in buildings by 2045, based on technical and economicalconditions. Furthermore, an interview study has been conducted to examine incentives for district heating customers to invest in energy efficiency measures.Result of the Excel model shows that the district heating volume of Vattenfall in 2045 is expected to 931 GWh, which corresponds to a volume decrease of 10,6 %. Based on the study?s theoretical framework only 15 %, 1 024 GWh, of the technical-economical potential is assumed to be implemented.

Tidig extubering efter hjärtkirurgi : Intensivvårdssjuksköterskans kunskap om tidig extubering och deras syn på faktorer som påverkar tiden till extubering

Early extubation of cardiac surgery patients has become increasingly important. The assessment of the patient before an early extubation is crucial and the intensive care nurses (ICU nurses) in this estimation is there for very important.The aim of this study was to examine critical care nurses' knowledge of early extubation, and what view ICU nurse has about factors that affect the time to extubation of cardiac surgery patients.A quantitative approach with descriptive and comparative design was used. Selection was all ICU nurses at a thoracic intensive care unit who were clinically active in patient care.The study showed that ICU nurses had good knowledge of why an early extubation was essential. However, the knowledge about the unit?s extubation criteria was low.

Affärsänglars riskbedömning -Risk och osäkerhet vid utvärdering av investeringsförslag

Affärsänglar spelar en mycket betydelsefull roll för svenskt näringsliv. De är en viktigkapitalkälla för unga och nystartade företag då de bistår med kapital till riskfyllda och osäkraprojekt som inte attraherar andra finansiärer på marknaden. Syftet med föreliggande studie äratt förklara varför affärsänglar väljer att gå in med kapital i företag där andra finansiäreravstår på grund av risk och osäkerhet. Målet är även att redogöra för hur affärsänglar bedömerett investeringsförslag utifrån ett riskperspektiv. Genom att ta del av tidigare forskning somberör utvärderingsprocessen har vi arbetet fram ett antal faktorer som kan påverkariskbedömningen.

Flygburen laserskanning kopplat till skördarmätning för datainsamling till operativ planering :

The requirements for operative planning activities are increasing. The forest industry wants to gain better control over wood flow. A felling that is more market adjusted is desirable. However, this causes problems in the operative planning process because of the data collection methods used today. Data about timber assortments and data about the distribution of the tree diameter, etc., are often lacking. Airborne laser scanning is used to a greater extent than before for estimation of forest variables and should perhaps be used to the same extent in operative planning activities as well.

stödsystem: en studie av svenska vindkraftsproducenter

Uppsatsen behandlar de svenska vindkraftsproducenternas uppfattning om vilken effekt som övergången från miljöbonus till elcertifikat orsakar på deras finansiella risk. Syftet med denna uppsats är att bland vindkraftens elproducenter undersöka vilka effekter som kreeras av den finansiella riskens förändring när miljöbonus successivt försvinner och ersätts av ett elcertifikatsystem. Uppsatsens syfte undersöktes genom att intervjua 30 respondenter via telefon. Vindkraftsproducenternas uppfattning är att övergången från miljöbonus till ett elcertifikatsystem orsakar en ökad finansiell risk vilket beror på två faktorer som påverkar den kortsiktiga och den långsiktiga finansiella risken. Dessa faktorer är informationsbrist om elcertifikatmarknadens utbuds- och efterfrågekurva samt volymvariationer i elproduktionen.

Trycksår hos patienter med ryggmärgsskada : - en kvantitativ jämförande observationsstudie

SAMMANFATTNING BAKGRUND: En patient med ryggmärgsskada [RMS] har en livslång ökad risk för trycksår på grund av sitt rörelse- och känselbortfall. Av alla med RMS i världen får upp till 95% trycksår minst en gång under sin livstid. Det finns idag ingen bra riskbedömningsskala avseende trycksår hos RMS-patienter, då de enligt den vedertagna Modifierade Nortonskalan får en missvisande låg risk för trycksår. Med kunskap om riskfaktorer, information och utbildning går det till stor del att förebygga uppkomsten av trycksår.SYFTE: Syftet med studien var att kartlägga förekomsten av trycksår hos nyskadade/nyinsjuknade patienter med RMS samt att undersöka vilka faktorer som visar på risk för trycksår.METOD: Studiedesignen var en kvantitativ jämförande observationsstudie där data samlades in longitudinellt och prospektivt. Skillnader mellan nyskadade/nyinsjuknade RMS-patienter med och utan trycksår studerades.RESULTAT: Av de 61 patienter som deltog i studien hade 35 (57,4%) trycksår någon gång under vårdtiden.

Kustnära ekosystem som skydd mot naturkatastrofer : en litteraturstudie från ett riskhanteringsperspektiv

Research suggests that society's vulnerability to natural disasters along coasts could increase as a result of climate change, which is likely to lead to elevated sea levels and possibly an increase in the occurance of meteorological phenomena such as storms and tropical cyclones. Following the Indian Ocean tsunami disaster in 2004 and Hurricane Katrina in 2005, both of which received considerable media attention, empirical data has indicated that coastal vegetation might be able to protect and reduce damages to coastal communities during tsunami events and tropical cyclones.The aim of the essay has been to study the function of coastal ecosystems as protection against tsunami waves and storms from a risk management perspective, meaning that I have, through an overview of scientific articles, compiled current research on how coastal ecosystems can attenuate storm surges and tsunami waves, and analysed how this knowledge can be put into practice in coastal communities from a risk management perspective, i.e. if coastal ecosystems are a viable risk reduction measure, are practically applicable, and if so, how they could be applied.There is empirical evidence suggesting that coastal ecosystems, particularly mangroves, can reduce the strength of a tsunami wave, but full scientific consensus on this issue has not yet been reached. With regard to protection against storm surges, there is extensive scientific evidence that coastal vegetation can mitigate damages and reduce the height of a storm surge, although the wave has to traverse several kilometres inland through thick vegetation for the protection to be effective. A synthesis in the form of a figure regarding the many physical factors that influence wave development through coastal ecosystems has been created in an attempt to simplify and explain the phenomenon.The conservation and restoration of coastal ecosystems can be justified from a risk management perspective, but planting new forest belts for the purpose of disaster mitigation is quite unrealistic and can rarely be sustainable, since, for protection to be effective, the forest belt must extend several kilometres inland from the coast, and would thus likely prove difficult to implement along coastal societies..

Hypoadrenokorticism hos storpudel :

Hypoadrenocorticism (Addison´s disease) results from insufficient production of glucocorticoid and mineralcorticoid hormones from the adrenal glands. The disease is often difficult to diagnose in an early stage because of the multitude of associated vague clinical signs. The standard poodle is one breed presupposed to be at higher risk of developing the disease. The purpose of this study was to give a review of canine hypoadrenocorticism as described in literature, and to characterise Addison´s disease in a population of standard poodles in Sweden. Statistics on incidenceproportions by breed for hypoadrenocorticism from the database of the Swedish insurance company Agria are presented.

Modellering av reflektans från ett sockerbetsbestånd med hjälp av en strålningsmodell

The Multispectral Canopy Reflectance Model (MCRM) by Kuusk (1995) has beenused to simulate the reflectance of a sugarbeet canopy. The simulated reflectancevalues show high absorptance in the VIS area, compared to field measurements, andhigh reflectance values in the NIR area. The errors may be due to overestimation ofclorophyll content in the sugarbeet leaves and scattered light during fieldmeasurements. The estimation of the clorophyll content where carried out using thePROSPECT-model by Jacquemoud & Baret (1990).During the vegetation period, the state of the canopy moves towards a closed canopy,with sparse vegetation in spring. The MCRM-model was used to perform a ?spring?simulation, which was compared to the original simulation.

Samverkansavtal, medbestämmande eller kringgående av MBL?!

AbstractIn this study, then collaboration agreement impact of the work on 11 and 19 § § MBL are studied. The employer and collective agreements bearing employee union are often involved in collaborative agreements to facilitate cooperation between them. Issues addressed to collaboration areoften questions related to employee participation. The purpose of this study is to investigate two local employers and related collective bearing employee unionsview of the cooperation agreement related to the MBL. The purpose leads to these questions:?How can co-operation agreements affect 11 and 19 § § MBL??What are theadvantages and disadvantages cooperation agreementscan lead to, regardingemployer disclosure and negotiation duty?To try to sort out these issues are interviews conducted to create a greater understanding of the work of the Cooperation Agreement between organizations and how it affects them.Results of the study suggest that collaboration agreement leads to simplifications in the work of the employer's information and bargaining duty.

Mot en beskrivning av miljömedvetna konsumenters informationsbehov

AbstractThe aim of this Master thesis is to explore why some Swedes want to consume?eco-friendly? and whether this fact gives rise to articulated information needs. Two possible explanations for this ?eco conscious? consumption are being tested, either if it is based on a normative belief that it is the right thing to do if you, as a consumer, want to do something about the environmental degradation, or that it is a reaction to a perceived risk, due to the environmental degradation. The method chosen by the author in this thesis is a qualitative text analysis of five Swedish journals.
