SAB-systemets utveckling 1985-1997
The aim of this Master's thesis is to compare the 6th and the 7th editions of the classification scheme of the Swedish classification system (SAB) to reveal which principles are used concerning the development of this system during the period 1985-1997. Guiding questions are: What kind of changes has been conducted? How do these changes relate to development of other general classification schemes and to theories concerning revision work? The results of the analysis show that possibilities to use synthesis have increased by an extension of use of geographic and chronological subdivisions. The classification scheme has also been easier to use by elimination of parallel subdivisions and regularization of the scheme. To maintain stability revision is performed on selected subclasses.
Syntes och struktur i SAB förr och nu: En studie av avdelningen för språkvetenskap genom den första, den fjärde och den sjunde upplagan
The aim of this masters thesis is to examine the synthesis and the structure of the main class for linguistics F in the Swedish classification system SAB. We want to find out whether F has developed towards a more faceted structure or not. Our theoretical perspective is based on fundamental principles for modern classification. To carry out our investigation the first, the fourth and the seventh edition of SAB is analysed and compared. The results of our study show that the main class F has become more faceted and therefore the possibilities to use synthesis have increased.
Klassifikation av litteratur om film och TV ? En komparativ studie av Klassifikationssystem för svenska bibliotek (SAB) och FIAF Classification scheme for literature on film and television
The aim of this thesis is to compare two different classification schemes with each other and see what the differences and similarities are when classifying literature concerning film and television. One of the schemes is of general kind, Klassifikationssystem för svenska bibliotek (SAB) and the other is a special system, FIAF Classification scheme for literature on film and television. The focus of the examination is on comparing the structure, contents and division of firstly the main classes and secondly on comparing the notation and the auxiliary tables in the schemes. The theoretical framework of the comparison is based upon theory of classification but the conclusions drawn are though mostly of a more subjective character. In addition to the comparison itself interviews have been made with four libraries, two with experiences of SAB and two with experiences of FIAF.
Ryssland, Kina och deras nationella klassifikationssystem : En komparativ analys av BBK och CLC med DDC
In this two years masters thesis in Library and Information Studies, the Russian Library-Bibliographical Classification (LBC/BBK) and the Chinese Library Classification (CLC) are analyzed with regard to their historical and ideological backgrounds and their respective evolutions. The structure of these classifications is compared with the Dewey Decimal Classification (DDC), as well as three chosen subjects (History, Politics and Religion). A qualitative comparative textual method is used.The study shows that these classification schemes, created at different times, different parts of the world, and different political systems, have different biases but give priority to the European before other foreign views. Otherwise, they often use a proximity principle. The CLC and the LBC were originally based on Marxist materialist principles but built in totally different ways.
E-learning ? en utbildningsmetod och dess nytta
Companies that invest in e-learning have different expectations regarding the
outcome of the investment. According to literature and articles it is common
that companies see reduction of costs as the primary benefit with e-learning.
Therefore we ask ourselves the question if companies have attained the expected
benefit of the investment in e-learning and to what extent cost reduction have
been a determining factor in the investments?
The purpose of the thesis is to examine if companies that invest in e-learning
have attained the expected benefits. We also want to examine what the reason
for investing in e-learning is and if cost reduction is the primary reason for
investing.
The study is founded on a qualitative method that is based on a case study in
eight companies.
DDC:s avdelning 150 : en analys av psykologins klassifikation under perioden 1932-2011
This master?s thesis focus on Dewey Decimal Classification during the period 1932 to 2011, where the classification of the psychological knowledge domain is analyzed and discussed. In the light of the recent swedish switch from the swedish classification system SAB to DDC, this research area deserves prominence. The aim of this study is to investigate how DDC represents the historical development of the psychology subject with its underlying epistemology, to identify and analyze values and prejudice, and to analyze problems with DDC?s classification of psychology in relation to three other classification systems.
Underhåll av underhållsarbete
The traditional view of maintenance is machine-based, where acute maintenance tasks are highly valued. Preventive maintenance is viewed as secondary and less desirable to work with. The more modern view is to regard maintenance as a process. The machine-driven tasks are still necessary but are viewed as a part of the big picture.The purpose of this study is to examine how to high light general difficulties concerning maintenance management to aid organizations to reflecting upon their own situation. The study is based upon a pilot study initiated by ProcessIT concerning relevant key figures in maintenance.
Programmering av mikrokontroller för styrning av komponenter i ett biokemiskt analysinstrument
The Uppsala based company Q-linea develops procedures, instruments and systems for protein and nucleic acid analysis. The components in such an instrument are controlled by microcontrollers. Microcontrollers are computers in one singular chip that can be used in a wide range of applications such as cars, toys or in this case an analysis instrument. When developing a new instrument for biochemical analysis, Q-linea needed new software for controlling and communicating between the components in the instrument. The process of developing this software is the subject of this thesis.The project included research of microcontrollers and the components in the instrument.
Kunskap och organisatoriskt lärande inom Apoteket AB
This paper aims to provide a description of how knowledge can occur in Apoteket AB, anorganization that is operating on the Swedish pharmacy market. The purpose of this paper isalso to describe how the organizational learning occurs in the organization, and how theoutcome of this learning can be stored in the organizational memory. This subject is ofinterest since Apoteket AB experience changes in their external environment in that they nolonger have monopoly to sell pharmaceuticals on the Swedish pharmacy market. Earlierresearch claims that organizations need to develop new knowledge in order to take action, andthis development needs to be supported by the management within the organization.The collection of primary data was done by two qualitative interviews with employees withinthe organization of Apoteket AB.Our conclusions are that knowledge can occur in many forms, such as tacit and explicitknowledge. The vast majority of the knowledge within the organization is the information thatcan be found in the electronic database Aponet within Apoteket AB, and that is useful for theemployees in their daily work, and therefore is known as explicit knowledge.
Elektroniskt tillgängliggörande : En komparativ utvärdering av Google scholar och Summon
Electronic availability of information resources has increasingly become an important part of academic libraries everyday vocation. This is a fact that puts impetus on the libraries to know more about the way in which electronic information is being dispersed and handled. This thesis aims to comparatively evaluate Uppsala university library´s own metadata system Summon with the publicly available equivalent Google scholar. The evaluation is based on Péter Jacsó´s theories on database evaluation which concretely puts focus on Summon and Google scholar via the use and application of ten different criteria. The uses of precision and relevance criteria were also implemented as additional evaluation tools.
Det ekologiska valet : En konsuments väg till val av ekologiska livsmedel
This thesis examines the underlying components that affect consumer behavior regarding organic food. The thesis theoretical framework is based on Ajzen and Fishbein?s The Theory of Reasoned Action combined with theories regarding involvement and routine purchases. The empirical material is based on a desk research with 19 research papers between the years 1994 till 2009 and sales statistics over organic food. The thesis conclusion shows that the underlying components when looking at attitude towards conventional food are price, taste, expiration-date and healthfulness. While the components for involvement in organic food is the environment, personal health and supply.

Prestation vid sönderdelning av GROT med olika typer av maskiner
There is a need for productivities data and data for different types of machines for comminution of logging residues. The lack of data and studies on GROT comminution makes it difficult to evaluate different chains for handling of residue fuels and make system analyses.Four types of machines with three different working principles were compared at six studies during winter conditions. Three to eleven trials during 9.5 to 30.7 minutes were made on each machine. Samples from the produced material at each study were sieved to determine the size distribution of the comminuted material. Samples were also taken from the studies for determination of moisture content.
Vektorkvantisering för kodning och brusreducering
This thesis explores the possibilities of avoiding the issues generally associated with compression of noisy imagery, through the usage of vector quantization. By utilizing the learning aspects of vector quantization, image processing operations such as noise reduction could be implemented in a straightforward way. Several techniques are presented and evaluated. A direct comparison shows that for noisy imagery, vector quantization, in spite of it's simplicity, has clear advantages over MPEG-4 encoding..
Vad står det där, Fröken? : Läs- och Skrivinlärning, samt svårigheter som kan uppstå.
AbstractI have chosen to make a study of the learning of reading and writing, as well as other learning difficulties that may occur, in this research.My choice of subject is based on the realizations I made during my time as a student teacher; that each teacher has his/her own way of teaching reading and writing. Sometimes, however, learning difficulties occur, and this insight caught my attention. It made me think about the underlaying reasons and how we, as teachers, can bring attention to these difficulties. With these questions in mind, I recorded my observations based on a series of interviews and literary studies in an attempt to answer my questions. The resulting research emphasizes how important the actions from the teachers are, as well the importance of having variety in your lesson plan.
