Vad förmedlar en förskolas barnböcker ur ett genusperspektiv? : En kvantitativ studie av 136 barnböcker
The purpose of this study is to investigate how male and female is produced in the literary children?s literature that is found in a Municipal preschool. My issues are the following:Which sex dominates as a main character in the preschools literary books?What type of properties is attributed to the characters?What type of clothes is portrayed on the books characters?I performed a quantitative study of 136 children?s books. I used Maria Nikolajevas perceptions of stereotypical male and female properties to analyze my empirical data.
Double integrating spheres: A method for assessment of optical properties of biological tissues
The determination of the optical properties of biological tissue is an important issue in laser medicine. The optical properties define the tissue´s absorption and scattering behaviour, and can be expressed by quantities such as the albedo, the optical thickness and the anisotropy coefficient. During this project, a measurement system for the determination of the optical properties was built up. The system consists of a double integrating sphere set-up to perform the necessary reflection and transmission measurements, and a computer algorithm to calculate the optical properties from the measured data. This algorithm is called Inverse Adding Doubling method, and is based on a one-dimensional transport model.
Hur tillförlitlig är värderingen av förvaltningsfastigheter?: En studie av tillämpningen av IAS 40
This thesis studies the way valuation of investment properties is conducted in accordance with IAS 40 and how reliable these valuations are. This has been conducted by studying ten Swedish real estate companies listed on the NASDAQ OMX, during the period 2005-2008. The study shows that all companies use valuation models to determine the fair value of investment properties. Two different types of models have been identified. Companies that use the cash flow model show inconsistencies in time horizon, and how they determine the horizon value.
Institutionella omgivningen i förändring
The purpose of this thesis was to examine relevance of the proposition made by new insitutionalists about institutional and technical environment. This proposition originaly made by Meyer & Rowan (1977) has two core assumptions: The first is that all organizations are controlled by combinations of types of demands; technical demands for efficient production and institutional demands to adept to cultural and normative expectations. The second assumption is that there exists a few organizations dominated almost entirely by one typy of demand. Organizations dominated by institutional demands are said to live in an institutional environment, while technical organizations is said operate in a technical environment. This thesis has examined if these assumptions are still applicable in describing organizational interaction with the environment.
Vetenskap, Teknologi och Ontologiska frågor
This essay is a study that takes interest in technical and technological change essential to philosophy of science. What is shown is the importance of an active attitude towards this change, by the articulation of the question: Does technical development lead to new ontological questions for science? - and by the answer that such questions do appear.It is clear that passive assumptions in this matter might prohibit science in the proceeding search for truth.By examples of ways in which technical development helps and challenges science, it is concluded that scrutiny of the relationship between technical development and ontological suppositions and hypotheses within science is well motivated..
Projektledning inom mjukvaruutveckling : En studie om betydelsen av teknisk kompetens utifrån projektmedarbetares perspektiv
More than half of the implemented IT-projects go over budget, deadline or simply fail. The processes in an IT-project requires technical competence to be present among the project participants to ensure the achievement of business goals and to make organisations competitive. The success of an IT-project largely depends on the project manager which makes it interesting to further investigate what impact the project manager?s technical competence has on the project. Previous research shows differing opinions whether technical competence is considered important for the project manager to be successful or not.
Småhuset ? val av bergvärme, fjärrvärme eller pellets
This thesis describes the new construction of a small house and it includes studies of three heating systems: geothermal heating, district heating and pellet. The purpose of this thesis is to project a small house which can manage Building Regulations, BBR conditions and then examine three possible heating systems for the small house. This thesis is a literature study which gives an understanding of the heating systems technical structure, properties and costs. An empirical study completes the literature study by giving a deeper understanding of district heating costs and pellet costs. The empirical study contains two interviews, one of which was conducted in a district heating corporation and the other interview was conducted in a pellet corporation.

Tuftade ljudabsorbenter ? väggpaneler för rumsliga och akustiska egenskaper
It is a well-known fact that textiles and carpets have benign sound-absorbing properties. It is desirable to have quantified values of these properties ? especially for architects and interior designers. They often need to be able to giveaccount for the acoustic properties of their designs at a relatively early stage and sometimes have strict acoustic classifications imposed upon them by their contractor. A product with documented acoustic properties would aid when prescribing interior elements.The purpose of this thesis is to develop a wall-mounted panel in hand-tufted material ? aesthetically pleasing and versatile but also having documented and quantified acoustic properties.
Finansiering av strategiska investeringar : - en fallstudie av Home Properties
Ett företags kapitalstruktur och i förlängningen dess val av finansiering för strategiskainvesteringar omgärdas av motstridiga uppfattningar och teorier. Vi har genomfört enfallstudie av Home Properties AB, ett renodlat hotellfastighetsägarbolag noterat påStockholmsbörsens lista för medelstora bolag.Uppsatsens syfte är att beskriva hur Home Properties agerar och resonerar vid finansiering avstrategiska investeringar och jämföra beskrivningen med Åkerbloms hypotes om sär- ochsamfinansiering, pecking order teorin och static trade-off modellen. I syftet ingår också att geförslag på vidare forskning.Enligt pecking order teorin prioriterar företag internt kapital framför externt. Vid finansieringav strategiska investeringar väljer Home Properties emellertid inteckningslån först. I HomeProperties fall förklaras företagets val av finansieringskällor bättre av static trade-offmodellen och Åkerbloms hypotes om sär- och samfinansiering.
Plastfilmsöppningar till Tetra Paks förpackningar : En teknisk introduktion och tidig konceptutveckling
This master thesis is an early concept development project about using plastic films and sheets as materials for shaping openings for Tetra Pak packages. It is also a technical introduction highlighting the areas of importance for the development of plastic film and sheets openings. The master thesis has been carried out as a co-operation between Chalmers University of Technology, KTH Royal Institute of Technology and Tetra Pak AB.The master thesis study presents an introduction that gives an understanding of the technical complexities and design possibilities of using thin plastic films and sheets in liquid carton openings. The knowledge is then transferred into five design concepts which points out the areas of opportunity. The technical introduction is widespread and extensive covering current packing trends, the liquid carton package and openings, thermoplastic material properties, and thin film and sheet manufacturing and shaping.
Underhålls- och driftplanering inom Svenska kyrkan : Hur ser kontrollen ut hos en av Sveriges största fastighetsägare?
This diploma work handles how some parishes of the Swedish Church administrate their building properties.The report also includes how some external property managers in Sweden work with maintenance plans and other maintenance issues. Further, a number of deficiencies have been identified and suggestions to workarounds are treated. The conclusions drawn in this thesis are based on the author´s experience in the field, performed interviews, and literature studies. The result of the work shows a general lack of knowledge in many parishes what concerns regulatory requirements, properties with no maintenance plan and substandard supervision resulting in unnecessary and expensive repairs. Based on these results, different plans for the maintenance of the building properties of the Swedish Church has been proposed..
Det sociala och det tekniska: Möjligheter för Aktör-nätverksteorin inom biblioteks- och informationsvetenskap
This thesis discusses and analyses the existence of two different perspectives, a social and a technical one, in Library and Information Science (LIS). Most of the time the division between these perspectives seems to result in research only using either of them. This can be a problem when studying complex phenomena. We therefore see a need for a metatheory that unites the social and the technical. By presenting and analysing all doctoral dissertations published at the Swedish School of Library and Information Science (SSLIS) 1993-2005, we try to detect and critically discuss the dichotomy between the two perspectives.
Den icke-monetära nyttans betydelse för prisbildningen på skogsfastigheter : en intervjuundersökning
The market value of forest properties can be assumed to consist of two components, a monetary factor and a non-monetary factor. The objective of this examination paper is to study the impact of non-monetary factors on the values of forest properties in Sweden. This study is based on a population of buyers of forest properties in the southern of Sweden. The results are based on interviews with 54 buyers. Of the purchases were 37 % new purchases.
