Fullkontakt eller glappkontakt? : En jämförande studie om regelverket för revisorns oberoende

The independent audit function plays an important role in our modern society as it strengthens the credibility of information given out by firms. A fundamental condition for the maintenance of confidence towards the audit function is the auditor?s independence. This phenomenon has been acknowledged threw several well-known audit scandals during the last decade, including the classical Enronscandal. In the repercussions of these huge auditing scandals, governments all over the world were now founding more restrictive rules and laws about audit independence.

Tillämpad informationsteknologi i klassrummet

This bachelor thesis in science Informatics contains the qualifications for the applying of IT in education for students in elementary school, grade 1-3. By empirical case study on an existing elementary school, whose success on IT use is noticed, describes how to apply IT in the classroom in an adequate way. We look at different theoretical frameworks in interaction and design of systems designed for learning purposes, and satisfies their specific needs and situations within the classroom's four walls. The current lack of statistical measurements on students' results and effects of the use of IT in teaching, prevents further improvements. If we simultaneously work to develop more well-designed systems that are designed for this purpose, it is possible that the effects become more and better.

Fantastisk litteratur och inskränkta fans : Tolkning och meningskapande i Science fiction forum 1960-1980

This Master´s thesis examines the conceptual ideas of science fiction and science fiction fandom produced in the Swedish fanzine Science Fiction Forum (1960-) between the years 1960 and 1980. Science Fiction Forum was and still is a fanzine published by Skandinavisk Förening för Science Fiction (Scandinavian Science Fiction Club). Both the club and the fanzine are a part of the phenomenon called fandom.A fandom is a collective of people called fans who form a community by sharing a special interest in a special object. The fanzine is one of the many material products produced by fans within a certain fandom. Science Fiction Forum and Skandinavisk Förening för Science Fiction were founded in 1959 and are a part of swedish science fiction fandom, where the object of fandom is literary science fiction..The primary focus of this thesis is the meta discussion on science fiction and science fiction fandom in Science Fiction Forum.

ATT HANTERA SIN BRÖSTCANCERDIAGNOS : En litteraturstudie om copingstrategier hos kvinnor

Cystisk fibros är en genetisk sjukdom som leder till andningsbesvär, infektioner i lungorna och rubbat näringsupptag i tarmen, vilket resulterar i besvär i GI-kanalen samt dålig viktuppgång. CF orsakas av en mutation i CFTR (cystisk fibros transmembran regulator) genen vilket medför en minskad kloridutsöndring som orsakar en ökad natriumreabsorption i cellerna. Detta leder till en minskad förmåga för slemmet i luftvägarna att binda vatten, vilket gör att det blir segt. Det finns inget bot för sjukdomen och den rådande behandlingen är både tidskrävande och livslång. Syftet med den medicinska behandlingen är att göra det sega slemmet i luftvägarna mer lättflytande och förebygga infektioner.

Skapandet av en snackis : En studie av marknadsförares väg för att nå ut i reklambruset

Today there is something called clutter. Marketers are trying to communicate so many messages to consumers that it makes it difficult for consumers to take in the different market messages that exist.In this paper the authors study how marketers can reach out with a message in today's clutter. They are doing a case study of a marketing campaign which tried to solve the communication problems that clutter is causing. The goal of this campaign was to create a snackis, a Swedish word for a current topic, to reach out with their message. The campaign attracted attention from the media.

Alla pusselbitar behövs : En fallstudie om interprofessionellt teamarbete i äldreomsorgen

When the population is getting older, the need for complex care and nursing interventions in elderly care increases. To create a holistic view of the elder and their life situation, interprofessional team collaboration is often desirable and necessary. Teamwork is often described in positive terms, but previous research has shown that this work method is complicated and requires constant reflection and development. The purpose of this study was to investigate how elderly care teamwork is formed in the interaction between representatives of different professionals. To accomplish this purpose, we have studied how the team members define a well-functioning teamwork and difficulties, and how consensus is achieved in the team.

Insatser och åtgärder för främjandet av laddelbilar i Sverige

To achieve the goal of fossil independency in the Swedish vehicle fleet in 2030, it would be important to substantially increase the proportion of electric vehicles, both BEV:s (Battery Electric Vehicles) and PHEV:s (Plug-in Hybrid Electric Vehicles). The Swedish Energy Agency has funded numerous research and development projects about electric vehicles in recent years. An important task for the Swedish Energy Agency is to allocate state funds to those projects with the greatest potential to contribute to increased establishment of electric vehicles in society. The purpose of this work is mainly to understand the efforts and measures that can make the market for electric vehicles to grow. The report can contribute to a better understanding of how far the research on electric vehicles has come and what has to be done in the future to promote the establishment of electric vehicles. Another aim for this report is that it should serve as a basis for future decisions by the Swedish Energy Agency on which projects that will be funded with state funds.

?Ett mångkulturalistiskt jippo? : En kvalitativ studie av Sverigedemokraternas relation till religion och den svenska identiteten

The rise of the Swedish Democrats, as a political party in Sweden, has been surroundedby controversy both within and outside of the media. As such a polarizingtopic, the party has been the focus of negative and positive attention. On onehand it has been considered a racist and xenophobic party due to its policies onimmigrants. On the other, it has also been seen as a solution to what has been consideredby some to be a constant problem in Sweden, for those same policies.These policies are motivated by what the party perceives as a threat to Swedishsociety. That is to say, immigrants are a threat to Sweden because of thechanges they impose on the Swedish identity.

Underlag för bedömning av energibrunnar inom vattenskyddsområde

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

Lärarrollen i förändring : En intervjustudie om lärares inställning till en förändrad lärarroll

During the past twenty years, the Swedish school systems have slowly changed to becomemore and more performance-driven. Private schools have been growing in general and, likeindependent schools and schools managed by municipalities, they profile themselves. Schoolsare becoming more performance and result-oriented, which has changed the roles of teachersin a dramatic way and is in general, still changing.By profiling students based on theirindividual performance, schools are able to help students identify themselves and their owngoals. The process of profiling is a slow one in which some teachers adapt more quickly thanothers, and one that is critical for other teachers to learn in order to keep up with the demandsof society.Schools, like ordinary businesses, are in constant competition with each other to keep up withthe newest and greatest models of teaching and to rank among the best in high achievements.Perhaps the downside of this modern school structure is that it is often difficult to have aschool where both school management and teachers see eye to eye. School management must heavily focus on the school?s results as a whole.

Porslinskonsumtion sett ur ett generationsperspektiv: Köpbeteende - Generationskohorter - Porslinsindustrin

During the latest 50 years, the Swedish porcelain tableware industry has gone from being rather successful to experience significant problems. Our empirical study attributes these problems to underlying changes in consumer buying behaviour, whereas current generation theory supports our findings. The younger generation has significantly different preferences compared to older generations, with less focus on quality and more focus on variability, and there is reason to believe that these findings also are applicable to other consumer purchases. The successful porcelain companies of tomorrow will be the ones that continuously can adapt to these and further changes in consumer buying behaviour..

Miljöbetong

The study aims to reduce energy consumption in apartment buildings where individual metering and charging of heat is applied. The aim is to develop planning and design for individual metering and charging in apartment buildings.The study is based on literature review, interviews and case study that include analysis of existing documents. Interviews were carried out with the property developer and the involved consultants who planned the apartment building Yasuragi. To investigate the differences the condominium association has noted in heat consumption between flats, the debit values of the heat were used to discern which houses that were furthest from the average consumption. On these flats there were temperature measurements and thermal photo shoots made for discriminating behavior and possible construction techniques which could be the explanation for the heat spread.Boverket shows that the consumption of heat can be reduced by 10-20% after insertion of individual metering and charging in an apartment block.

En publik i förändring : En kvalitativ studie om det individualiserade tittandet i relation till användandet av VoD-tjänster

Purpose: The purpose of the study is to gain a deeper understanding of influencing behaviours concerning individualized viewing in relation to VoD-services (Video on Demand), and how this reflects the perceived viewing behaviour in terms of habits, content and social actions.Theory: The theory that primarily underpins this study is Jacob Bjur?s thesis Transforming Audiences. Bjur?s thesis provides an analytical model of individualized viewing behaviour that has been used in this study case. The model is founded on three central tenet areas of individualization, Habitualness that ensures habits, Socialness that refers to the social space and Referential space that ensures content/selection and viewership as a referential act.Method/Material: The study is based on a qualitative research method underpinned by focus groups interviews.Results: The research demonstrates strong tendencies towards an individualised viewing behaviour in the use of VoD-services.

Undersökning av steady state och utvärdering av valskraft och friktion vid kallvalsning av aluminium

The purpose with this thesis was to examine the cold rolling mill located at Högskolan Dalarna and to stabilize the rolling process, to achieve steady state. Experiments with cold rolling of an aluminium strip have given results for rolling force, friction, reduction, strip tension and strain hardening. Results show that steady state has been found for the experiments with roll force and strain hardening, and not been found for the experiments with friction and reduction. Results show that increased strip tension gives lower roll forces. The roll force equation of Stone shows comparable results with reality for dry contact with reductions up to 30 %, but starts being incomparable with higher reductions.

Vätgas och bränsleceller : Ny energi för Försvarsmakten?

The purpose of this paper is to identify the current status of fuel cell technology and to establish whether said technology is mature enough to be implemented into the Swedish Armed Forces. The question to be answered in this paper is as follows: Can hydrogen gas and fuel cells be used as an alternative source of energy within the Swedish Armed Forces?This paper is based on theoretical studies and reports from prior research done on fuel cells. By studying these facts a predictive answer has been obtained. The answer I have come to, is that the maturity of fuel cell technology is currently inadequate for the Swedish Armed Forces to implement, especially considering its harsh working conditions..
