Människans suveränitet över andra arter : En studie om två miljöorganisationers resonemang angående förlusten av biologisk mångfald

The purpose of this study is to exam how two environmental organizations reason about the loss of biodiversity. The research questions are; what is the view in these organizations regarding biodiversity? What are the underlying environmental discourses behind their reasoning, and how do they reason about the risks associated with the loss of biodiversity? As a first part of this thesis a thorough review of existing literature and online resources about the actions of environmental organizations was conducted. Two organizations were interviewed, World Wildlife Fund (WWF) and Naturskyddsforeningen. The questions for the study were analyzed in light of Dryzek´s (1997) reasoning about environmental discourses and using the concept of risk by Beck (1998).

Från webb till app : En studie i hur interaktions- och grafisk design påverkas i utvecklingen från webbplats till mobilapplikation

This paper reports a study in how interaction design and graphic design is affected in the process of developing an mobile application to complement the use of an existing webbsite. The paper also ask how developers are affected in this process by the use of designpatterns. The purpous of the report was to see how designpatterns affects the development of mobile applications and how the interaction and graphic design differs between various company webbsites and their related application. A study was conducted by comparing three diffrent webbsites with three related applications to find material for our thesis. Interviews were conducted on three diffrent companys that work professionaly with creating mobile applications.

Informationssäkerhet i arkitekturbeskrivningar : En studie i hur säkerhetsfunktioner kan beskrivas med hjälp av vyer

Information security is an essential part of all information systems; especially in large organizations and companies dealing with classified material. Every large information system has an architecture that includes many parts that together form an Enterprise Architecture. The aim of this thesis is to study how to describe several security functions in an Enterprise Architecture and also how to ensure accountability between requirements and the implementation of the security functions. The description is for stakeholders on a conceptual level rather than a technical level. The study has been carried out by comparing the theoretical framework that has been formed by a study of the literature, and the empirical framework that has been formed by a group discussion and interviews with Information Security Consultants from Combitech AB.

Byggnadsfysikaliska riskbedömningar : Metod för tidig hantering av fuktsäkerhetsfrågor

The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.

Teknisk utredning av skärutrustning till skördare : En analys av den svenska marknaden

Husqvarna is a world leading producer of chainsaws with a well-established brand name. Husqvarna now has an interest in investigating the possibiltiy to expand their production of chains and guide bars to include cutting equipment for timber-harvesters.This project is a technical study which aims to answer questions about cutting equipment for timber-harvesters that have been decided in cooperation with Husqvarna. The questions have mainly been focused on forces, cutting speeds, service and maintenance -as well as general questions regarding the size of the Swedish market.Two methods have been applied to answer the questions. Interviews with retailers of harvesters, producers of harvester heads and harvester drivers.The main findings in this project show that there is a relatively small selection of harvester chains on the Swedish market. In contrast to the selection of harvester chains the selection of guide bars is quite large.

Vad sägs om marknadsföring: En studie av 20 artiklar i svensk bibliotekspress

The aim of this thesis is to research if and in that case how, marketing of Swedish public libraries is used as a possible work method in a time when they are marked by changes in the form of cut backs and technical innovations. With a strive to get an overview by the possible debate I have chosen to do a closer exam of 20 texts published in five of the biggest Swedish library publications during a period of 20 years. My research is based mainly upon Philip Kotler?s marketing theories regarding non-profit organization as well as Eileen Elliot de Saéz interpretations of these to a library context. The first part of the essay therefore consists of an introduction of these, as well as a rendering of their method of work, which shows the width of the conception of marketing.

Vad är ett E-Arkiv? : En fallstudie på E-Arkiv Stockholm

The aim of this thesis in Archival Science was to explore the concept of electronic archives and the challenges that might be encountered when attempting to move archives into a new digital age, as well as having a closer look at the term e-archive itself. Another aim was to explore how the OAIS reference model works in practice.To explore these questions I decided to do a case study on E-Arkiv Stockholm, a functioning e-archive. I decided to do a study on several documents that were created throughout the project, these included documents related to the planning of the archive, as well as the final report. My reason for this method was that these docu-ments came straight from reality and would give a clear and unbiased view of the project and it?s many aspects.Examination of the documents showed that the OAIS reference model and its concepts had been the foun-dation of much of the planning.

Utveckling av biopsiinstrument : Instrumenthållare för skruvnålsbiopsi

This Master Thesis has been carried out in cooperation with Ursus Medical AB (URSUS) which markets, assembles and sells the Rotex Screw Needle Biopsy Instrument ®. The instrument is delivered with an instrument holder. Customers had expressed dissatisfaction over that they needed to use two hands during a biopsy procedure, which resulted in a project to develop a new instrument holder.The project aim was to create concepts for how the new instrument holder should be designed, with focus on the mechanics. The new instrument holder would build on the existing basic principle that the screw needle and the cannula were screwed into the tissue. The thesis work would result in a technical solution and a functional prototype of the chosen concept.To achieve this, a generic product development processes were used and began with a comprehensive literature review.

Reglerna om ränteavdragsbegränsningar : är tioprocentsregeln och ventilen i behov av en skärpning?

Den 1 januari 2009 infördes regler som begränsar rätten för företag att göra ränteavdrag, vilket har till syfte att förhindra aggressiv skatteplanering som sker genom ränteupplägg. Två undantag till denna begränsade rätt till ränteavdrag benämns tioprocentsregeln och ventilen. Genom dessa får ränteavdrag göras om mottagaren av ränteinkomsten beskattas med tio procent eller om förfarandet är affärsmässigt motiverat. Dessa undantagsregler har dock blivit utsatts för kritik. Kritiken som har framförts är att den aggressiva skatteplaneringen som sker genom ränteupplägg inte minskat trots tillkomsten av reglerna om ränteavdragsbegränsningar och det finns även frågetecken om tioprocentsregeln är förenlig med etableringsfriheten inom EU.
