Svensk kunskapsorganisationsforskning 1990-2002
The purpose of this study is to characterize the research in the field of Knowledge Organization, during the period of 1990-2002, focusing on the subject and the epistemology of these studies. The result shows that studies concerning representation, e.g. subjects such as classification, indexing and bibliographic description, are the most frequently researched areas throughout the period. Classification was more popular in the beginning of the period, but later bibliographic description, mostly with studies on metadata, became more visible, together with a growing interest in information retrieval. The theoretical discussions in the studies focused primarily on document analysis and the organization of digital documents.
Ett verktyg för konstruktion av ontologier från text
With the growth of information stored over Internet, especially in the biological field, and with discoveries being made daily in this domain, scientists are faced with an overwhelming amount of articles. Reading all published articles is a tedious and time-consuming process. Therefore a way to summarise the information in the articles is needed. A solution is the derivation of an ontology representing the knowledge enclosed in the set of articles and allowing to browse through them. In this thesis we present the tool Ontolo, which allows to build an initial ontology of a domain by inserting a set of articles related to that domain in the system.
Platsbaserad sökning : En metod fo?r filtrering och sortering av so?kresultat
Informationsso?kningar av olika slag sker dagligen va?rlden o?ver och so?kresultatet kan ma?nga ga?nger vara sa? stort att anva?ndarna har sva?rt att veta vilka so?kresultat som a?r relevanta. I denna uppsats har syftet varit att underso?ka hur so?kresultat kan filtreras och sorteras med hja?lp av platsbaserad so?kning fo?r att det ska bli mer relevant fo?r anva?ndaren. Genom litteraturstudie och intervjuer har det blivit mo?jligt att ta reda pa? hur ett so?kresultat skulle kunna filtreras och sorteras fo?r att mo?ta anva?ndarnas fo?rva?ntningar.
Framställning av digital höjdmodell för analys och visualisering av naturlik fiskväg : En tillämpning vid Strömdalens kraftverk, Gävle
Fiskvägar kan anläggas i anslutning till dammar för att överkomma de hinder som dammarna utgör mot migrerande fisk. En av de mest önskvärda lösningar som finns för detta är att anlägga naturlika fiskvägar, vilka har som syfte att efterlikna ett naturligt vattendrag. Ofta har dock dessa planerats för dåligt med avseende på exempelvis lutning och placering av ingången för att de ska kunna fungera riktigt effektivt. På grund av detta finns det behov av omfattande studier av topografi och kartering av området innan en fiskväg anläggs.I det här arbetet används topografin och de geografiska förutsättningarna för att studera möjliga sträckningar på en naturlik fiskväg förbi Strömdalens kraftverk i Gävle som en del av det fiskvandringsprojekt som Länsstyrelsen Gävleborg driver. I arbetet byggs en höjdmodell upp med hjälp av data från LiDAR (Light Detection and Ranging) och genom topografisk mätning, där mätpunkter från Global Navigation Satellite System (GNSS) och Totalstation används för att korrigera LiDAR-modellen över visst område.
Ämnesindexering av spelfilm
The aim of this thesis is to examine possibilities concerning subject access to fiction film, i.e. appropriate ways to describe fiction film for subject retrieval. Problems regarding subject indexing in general, and subject indexing of fiction film in particular, are identified, as well as the uniqueness of fiction film and film genres. Four types of subject aspects are discussed: form and genre, fictitious characters, setting, and general topics. Several guidelines, form- and genre lists, and subject headings lists are examined and treated as potential indexing tools.
Testeffekten som medel för att förbättra läsförståelse?
Swedish school children exhibit deteriorating knowledge results in terms of reading comprehension. Previous research shows that a method to increase the level of knowledge is the use of evidence-based learning techniques. Test based learning generates what is commonly referred to as a test effect, which proved to strengthen the relationship between learning and memory, as well as being applicable to various test formats. The purpose of this study was to investigate whether test based learning, in terms of learning english words leads to increased performance in a reading comprehension test, more specifically a cloze test. The study was based on a within-group design and was conducted three times over four weeks.
Weblogindex: En studie av weblogindex utifrån Lancasters processmodell över traditionell indexering.
Many new electronic publication systems have arisen in the past few years, one of them is the weblog. In 1999 there were 23 weblogs, today there are millions thus a need for organisation has appeared, both special metadata and subject indexes have been invented and created. Due to the large amount of the latter we have in this thesis decided to concentrate on those close by the Scandinavian weblogindexes. A more international perspective would however have been possible, as very little is written on the topic. We have looked at these selected weblogindexes, trying to determinate whether they agree with F.
Det växer ju inte i magen men det växer i hjärtat : En kvalitativ studie om adoptivföräldrars erfarenheter av adoption
To investigate adoptions are part of the social worker's duties. The aim of our study was to examine some adoptive parents, to internationally adopted children, experience of adopting, the time before the adoption, the adoption process, and the time after the adoption. The study is based on qualitative interviews with seven adoptive parents. Theoretical frameworks that have been used are a phenomenological perspective, the dramaturgical perspective of Goffman and the theory of rites of passage.The result of our study shows that the adoptive parents have tried ?everything? to be-come parents in a biological way before they came to the decision to adopt.
Kunskapsteori och kunskapsorganisation: En diskursanalys
This Masters thesis concerns epistemology in Knowledge Organization KO, as a field of study in Library and Information Science LIS. Using a theoretical model by Birger Hjørland and foucauldian discourse analysis as springboards, this study analyses three epistemological discourses in the practice of KO. The aim of the study is to show how these discourses are constituted and demarcated in relation to KO, as well as to examine how they fit into Hjørlands model. A brief historical outline of some epistemological trends in LIS is sketched, as well as examples of how different epistemological schools influence different parts of KO, e.g. information retrieval, indexing- and classification theory.
Det förändrade strandskyddet: gällande rätt och ansvarsfördelning
Arbetet i den här rapporten har koncentrerats på att ta fram vad som i nuläget är gällande rätt i strandskyddsbestämmelserna. Vi har använt oss av en vanlig juridisk metod och mest studerat lagtext, förarbeten, praxis och doktrin. Vi har inte velat lägga alltför stor vikt vid källor som tillkommit innan år 2009 eftersom de regler som nu finns till stor del har förändrat utseendet på lagrummen. Vi har undersökt hur det är tänkt att beslutande myndigheter ska arbeta med dessa frågor och hur strandskyddsfrågorna har skötts innan lagändringarna infördes. Vi kan konstatera att den ändrade lagstiftningen kommit att innebära vissa förbättringar i strandskyddsarbetet i och med samordningen mellan Miljöbalken och Plan- och bygglagen.
Tunnelseende : Vandringar genom Järnvägstunneln i Karlskrona
Ett öppnande Det händer ibland att vi upptäcker platser som lyckas erövra en speciell plats i våra medvetanden. Det är platser som sätter tankar och känslor i rörelse, och som för en lång tid framåt väcker nyfikenhet och engagemang. För oss har det ofta handlat om övergivna platser. Miljöer som formats av människans hand, men som övergivits i takt med att samhället förändrats. I sin bortglömdhet väcker de en svårbeskriven sympati, nästan som den till en gammal vän i behov av kamratlig omtanke.
Geoenergilösning för DN-huset
In this thesis proposals for different designs of a borehole thermal energy storage (BTES) have been developed for the building DN-huset in Stockholm, Sweden. To build a BTES results in savings in energy costs by approximately 44 %, i.e. 2 million Swedish crowns annually. Furthermore, a BTES would reduce the annual environmental impact with roughly 75-157 tonnes of CO2 equivalents per year, depending on how the electricity consumption?s environmental impact is estimated.
Mångkulturalism i svensk barnlitteratur?
The purpose of our master thesis was to investigate how a multicultural society is reflected in childrens books picture books, books for children and young people, published in 2002. We found this issue interesting since children of today experience a change in society, where people of many ethnicities, cultures and religions live together to a greater extent than before. Since children in their everyday life are exposed to these different cultures, we think they also should be exposed to them in the books they read. In order to enhance an understanding of why such books are important to children, especially immigrant children, we have in our thesis included a passage with childrens linguistic development, identification and stereotypes. Other passages concern libraries and their roles in a multicultural society.
Flerspråkiga Tesaurer: Att uttrycka ett och samma begrepp utifrån skilda kulturer och olika språk.
The aim of this paper is to investigate the problems in multilingual thesauri, with a focus on the problem of conceptual equivalence between different languages. This study compares the problems and solutions that have been carried out in the Eurovoc multilingual thesaurus with the ISO 5964 ISO 5964 is a guideline for establishment and development of multilingual thesauri. The Swedish descriptors in the subject area "education and communication", from Eurovoc have been observed and compared with the guidelines recommendations. The results show that, the majority of the investigated Swedish descriptors do not present any problem. Most of the terms that are used as descriptors are found in dictionaries and glossaries or appear with high frequency in Swedish websites.
Det vårdande mötet i hemmet
Home care services have had, and will have a major imortance in the future.
More people will be using home care services as a consequence of political
strategies but also as an effect of caretakers own wishes. The purpose of this
study was to illuminate the factors that are significant for a successful
encounter between a caretaker and a caregiver. The study is made as a
qualitative analysis of litterature. The data collection was based on Polit and
Hungler's model of information retrieval and the data analysis on Graneheim and
Lundman's model of analysis.
