Finansiell risk och lönsamhet i Svenska fastighetsbolag under 2008

Syfte: Studiens syfte är att analysera och undersöka om det finns något samband mellan den finansiella risken och lönsamheten. Det övergripande syftet är att se om valet av finansiell risk fungerar som finansieringsstrategi i verkligheten.Metod: Studien bygger på den deduktiva ansatsen där teorier kommer att testas och analyseras mot empiriska data tagna från årsredovisningar. Den kvantitativa metoden används då data från 305 stycken årsredovisningar ska användas för att finna om det finns samband och variation mellan finansiell risk och lönsamhet definierad som vinstmarginal, Rt och Re. Årsredovisningarna utgörs av sekundärdata som samlats in från databasen Retriever. De statistiska metoder som används är bland annat medelvärde, standardavvikelse, regressions- och korrelationsanalys, hypotesprövning och t-test.Resultat och slutsats: Såväl korrelation- och regressionsanalys som hypotesprövning och t-test visar att det finns samband mellan finansiell risk och lönsamhet definierad som Re.

Behandlingsmetoder och amningsförekomst vid bröstböld

Bakgrund: Amningens fördelar för mor, barn och samhälle är välkända. En komplikation vid amning är bröstböld. Medvetenhet om fördelar och nackdelar med olika behandlingsmetoder vid bröstböld och deras inverkan på fortsatt amning är viktig.Syftet: Att studera behandlingsmetoder och amningsförekomst vid bröstböld.Metod: Retrospektiv design från en journalgranskning genomförd på Södersjukhuset mellan januari 2006 och september 2008. Statistiska analyser genomfördes med Chi-två test, Independent samples T-test samt Fishers exakta test.Resultat: Totalt 139 kvinnor med bröstböld behandlades med nålpunktions-, pigtail- eller dränagebehandling, eller en kombination av dessa. Sextiotre procent pigtailbehandlades enbart och dessa behövde i mindre omfattning sjukhusinläggning jämfört med ej enbart pigtailbehandlade, samt resulterade i större andel av ett till tre sjukhusbesök.

Reliabilitet och validitet av två svenska versioner av Fatigue severity scale vid mätning av trötthet hos patienter med systemisk lupus erythematosus

Syftet med denna studie var att testa och beskriva aspekter av reliabilitet och validitet av två versioner av Fatigue Severity Scale (FSS) på svenska, FSS 1 och FSS 2, vid mätning av trötthet hos patienter med systemisk lupus erythematosus (SLE). Metod: Två grupper av patienter med stabil SLE, låg sjukdomsaktivitet och liten organskada inkluderades. Diskriminant validitet för FSS 1 testades på 32 kvinnor med SLE och 35 friska kvinnor. Följande test av FSS 1 och FSS 2 gjordes på 23 patienter med SLE: Tak- och golveffekter, intern konsistens, stabilitet över tid (test-retest) samt innehållsvaliditet uttryckt som faktoranalys och innehållsvaliditet sett ur patienternas perspektiv vad gäller FSS 2. Resultat: FSS 1 kunde signifikant särskilja kvinnor med SLE från friska kvinnor.

Analyzing the future of technology and society. Scania and the case of the Russian fuel market.

Issue of study: The development of technology and society is closely linked. Mutual dependency and complex interrelationships make straightforward analysis of issues regarding the future of technology and society hard to perform. Therefore, the study addresses the question of how organizations should describe and analyze the interactions of technology and society in order to gain a better understanding of what the future may bring. Purpose: ? To develop a method for analysis of the future course of issues regarding technology and society in interaction.? To apply and test the developed method through a case study, where it is used to analyze the future of the Russian fuel market.

Ip-telefoni med Skype som ett alternativ till PSTN för privatanvändare

The project is a practical and theoretical test of IP telephony with Skype in order to form a base for a comparison between IP-Telephony with Skype and the Public Switched Telephony Network (PSTN). PSTN is the common standard that most of us use for telephony today. The objective for the study is to simplify the choice between PSTN and IP-Telephony for the Swedish private customer user group. The project is supposed to answer the following questions. - How easy is it to start using IP-telephony with Skype? - How is the quality of IP-telephony compared to PSTN? - Are all services provided by PSTN available and accessible using the IP-solution? - How are the usability and the availability of support with IP telephony? - Is IP-telephony a cheaper solution and in that case under which circumstances? Within the project a collection of practical and theoretical tests have been performed to be able to form an opinion on the IP-solution in the following areas, installation, function, quality, usability, costs, accessibility and security. In order to study usability, a test group of ten persons have been used to evaluate the usability of the system.

Trollhättans befolkningsmål: 70 000 invånare år 2030. En analys ur ett byggentreprenadföretags perspektiv

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Effekten av frekvenskomprimerande hörapparater på taluppfattningen hos patienter med grava diskantnedsättningar ? En experimentell studie

A pilot study conducted on four patients, which we received from the Sahlgrenska University Hospital, who were all potential candidates for a cochlear implant. We fitted our test subjects with a pair of frequency compressing hearing aids called Phonak Naida V SP during the study and let them evaluate them for about seven weeks. Measurements made with monosyllabic words throughout the study showed significant differences in speech perception (p?0.05) compared to their regular hearing aids in 3 out of 4 cases. De-activation of the frequency transposed function showed significant decreases in 3 out of 4 cases compared to when it was activated.All test subjects were satisfied with the new hearing aids and chose to keep using them at the end of the study..

Association between animal-based measures and register-based welfare indicators in dairy cows : a study of the advisory service "Ask the Cow" and the web report "Animal Welfare Signals"

Animal welfare can be measured in several different ways; for example by using animal-based measurements. It has been shown that register data from the Swedish Official Milk Recording Scheme can be helpful when identifying herds at risk of having poor animal welfare, which led to a development of the advisory service of ?Ask the Cow? and the web report ?Animal Welfare Signals?. The aim of this project was to find out if register data from ?Animal Welfare Signals? can be used as a screening tool for detecting herds at risk of having poor animal welfare and in need of an ?Ask the Cow?.
