Återvinning av skönlitteratur - Återvinningsverktygens anpassning efter användares sökbeteenden : En fallstudie på Trelleborgs bibliotek

Traditionally the content of fiction has not been described, analyzed, classified and/or indexed to the same extent as non-fiction. As a consequence, this lack of content analysis has resulted in unsatisfactory fiction retrieval in relation to users seeking and search behaviour. This fact is why this Master s thesis is written. The total of library users' seeking and search behaviour is investigated in order to suggest methods to improve user adapted fiction retrieval tools. Suggesting relevant fiction retrieval tools corresponding to users' seeking/search behaviour is another aim of the study.

ITis och IT inom Orust kommun : en kvantitativ utvärdering av ITis och IT inom Orust kommun och kranskommunerna

The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.

Gymnasieelevers informationssökning : En undersökning av Carol C. Kuhlthaus modell

The aim of this Masters thesis is to, through user studies, analyse whether Carol C. Kuhlthaus information search model is applicable in a Swedish school. Furthermore, the guidance that the students may receive from the teacher and/or school librarian is analysed. Answers are sought to the following questions: · How do the students perceive their information seeking? · How do the librarian and/or teacher support the students during their information seeking process? The study is based on a qualitative method of approach, through interviews with four informants: a librarian, a teacher and two pupils.

Mediebilden av cancersjuka ur ett genusperspektiv

AbstractTitle: Cancer in media from a gender perspectiveNumber of pages: 33 (49 including enclosures)Author: Emma KreüTutor: Amelie HössjerCourse: Media- and Communication science DPeriod: Spring 2007University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: The aim of this thesis is to investigate if there are differences between the picture given in media of women with cancer and of men with cancer. The result is aimed to give a deeper picture of how gender is represented in media.Material/Method: The method used in this thesis is discourse analysis, applied on twenty articles which contained personal interviews with women and men who have or have had breast or prostate cancer. Ten of the articles contain interviews with women and ten interviews with men. The articles were selected from criteria based on where and when they were published. They were picked from the two largest papers in Sweden, Dagens Nyheter (DN) and Aftonbladet (AF), ten from each paper, of which five were interviews with women and five with men.

Söka eller browsa? : En undersökning om personliga mönster i sökbeteendet vid informationssökning på nätet

This Master's thesis in Library and Information Science aims to explore if personal patterns can be detected in web-searching. It is based on a study where the search sessions of nine test persons were video-recorded, transcribed into logs and analysed.A major objective was to find out whether there is a correlation between individual searchers' personal attributes and their web search behaviour. The logs were therefore compared with the test persons' results in a learning style test (Kolb's Learning Style Inventory) and with interview answers about information behaviour and personal background.While several patterns were indeed discovered, none of them turned out to be strictly personal. The nine test persons could be divided into five types of searchers: the purely analytic searcher; the generally analytic searcher; the balanced searcher; the mixed searcher and the browser. All types of searchers were found to have the attribute learning style in common.

En tesaurus som ledsagare ? En jämförande studie av tre sökstrategiers inverkan på återvinningsresultatet i en bibliografisk databas.

This Master?s thesis is a comparative study of information retrieval results between three distinct search strategies in simulated automatic query expansion in a bibliographic database. Our purpose is to investigate which of the search strategies score the most effective precision and to what extent the same relevant documents are retrieved (overlapped). A thesaurus attached to the database is used to select appropriate descriptors for the baseline query formulations which subsequently are expanded with hierarchical relations. The search strategies are s1: A baseline query with two or three descriptors, s2: The baseline descriptors combined with at least one Narrower Term, s3: The baseline descriptors combined with Narrower Term and at least one Broader Term.

The Green Evolution of the Car Industry

This Master Thesis covers the concept of Green Cars. The background to the research area is the high and rapidly growing number of cars, which together with other factors ad to the pollution of the environment. Under the Kyoto agreement the signing members agreed to lower the emissions of green house gases, further on the EU has a 3-pillar strategy on carbon dioxide and cars. Included in the EU strategy is a voluntary commitment from the car industry to reduce carbon dioxide emissions from new cars. The easiest way of lowering the emissions is by using alternative fuels and engines.

Folkbibliotekariers användning av sökverktyg på webben i referenstjänst

The web is a constantly growing medium that presumably plays an increasing role in public library reference services. In order to provide high quality reference service the librarians need to be able to master this medium. Therefore it is interesting to get an understanding of how librarians actually use the web. The aim of this Master s thesis is to investigate what web search tools are used by public librarians in reference service. Furthermore, the aim is to get an understanding of how the librarians think about those tools and what background factors influence their selection of tools.

JAG - Vem är det? : En studie om bilden av identitetssökandet hos unga flickor och pojkar i 2010 års barn- och ungdomslitteratur

Last spring I did a study where I studied how young girls where being depicted in Swedish novels of 2010. My ambition with this exam is to study how young teenage boys are being depicted in Swedish novels of 2010 and to compare this study and the results with the results from my study last spring. Throughout history we can see that boy?s novels have had the purpose to bring up boys into being adventurous. In the novels of 2010 we can see that boys now are being depicted in another more modern and contemporary way.From my analysis we can see that all the books have many things in common.

Ledföljdsvariation i svenska : Verb, semantik och syntax i samband med lång objektsflytt

The term ?Object Shift? means that a weak object pronoun has been raised to a position to the left of a sentence adverbial. Primarily, there are two positions to which a weak object pronoun can be raised; one of them is called Long Object Shift.In this paper, I primarily deal with finite verb frequencies in sentences with Long Object Shift in Swedish. Also, in order to further define the verbs in these sentences I discuss verb semantic and syntactic valence in relation to the shifted object. Furthermore, I discuss the search methods which have generated sentences with Long Object Shift in written sources in Swedish; an equivalent study has never been done before.

Oljetemperaturens inverkan på motoroljans degradering i lastbil

The market for heavy duty engines is constantly requiring engines that should be more andmore powerful, while still maintaining low fuel consumption. As a result of increasing enginepower, the engine and coolant temperature increases as well due to insufficient coolingperformance (because of design issues, cost etc.).Also, emission legislations, both current and future, require more and more measures to betaken by engine manufacturers. One way of meeting the legislations is the use of cooled EGR(Exhaust Gas Recirculation), which also lead to increased coolant temperatures.Both these factors also naturally lead to increased engine oil temperatures, the consequencesof which are not thoroughly investigated.This thesis project aims to investigate effects of high temperatures on engine oil degradation,with focus on the greatest degradation process: oxidation. To do this several engine runs havebeen performed on a 310 hp engine with EGR to see what happens to the engine oil in a realengine when exposed to high temperatures. During the tests oil samples have been taken andanalysed for important parameters.As a complement to these engine tests some laboratory oxidation testing have also beenperformed, to be able to compare engine test data with laboratory tests.One goal of the project was to try to formulate an empirical oxidation model, which would beable to predict oil oxidation levels in an engine, given any running parameters.

Probleminventering av några forskares informationshantering : En fråga för biblioteket?

The aim of this Master?s thesis is to investigate if the library can be a real partner for researchers in managing and dealing with their research information. In this study, six researchers have been interviewed about their problems with information management. This study uses the method Critical Incident Technique for the interviews with the researchers. This method focuses mainly on problems and what happens around those problems.

Konsten att synas och skapa långsiktiga relationer med kunder : En studie om Sociala Medier och Sökmarknadsföring

The use of internet is growing rapidly and many people choose to spend a lot of their time in the virtual world. This is the reason why we believe that it is important for companies to consider using internet as a tool to reach their customers. Today many companies, especially within the fashion industry, have acknowledged this and use internet marketing to reach existing and potential customers. Social media and search marketing are two helpful tools that can be used in order to make a company visible on the web, given that they know how to use them effectively. The purpose of this study is to examine how companies within the fashion industry can use social media and search marketing to reach their customers and what kind of attitude they have towards using these tools.

EU-information : Studenters behov och sökning, EU:s informationsresurser

The aim of this master thesis was to examine the European Commission's information resources from a user perspective in order to clarify the needs and circumstances of the search of EU-information among students at Örebro University. 41 students participated in a survey, and four of them was interviewed. On the basis of Pendelton- and Chatmans theories of information behaviour in small worlds, it were assumed that the students' education and citizenship in the European Union affected their needs and the search of EU information.The study showed that the students needs for EU-related information has increased, with the current education, but also been linked to earlier educations. The students Citizens need were mainly associated with elections such as the EMU-election, but also in some cases to a need of the general knowledge.A review of the European Commission's information resources were made with an emphasis on European Documentation Centre, EDC. The survey showed that most students used the EDC and the EU-databases that was made available by the European Commission through the EDC and the university library but were not aware that they used EDC.The survey also showed that students made use of familiar sources and resources when they searched the EU-information, such as the library's regular database list, the library catalogue and search engine on the internet are not requested of other resources.

Informationssökning för barn och ungdomar politiska dokument och konkret verksamhet

The topic of this essay is information seeking for children and young people in municipal libraries. This is based in the growing need for information seeking skills in the Information Society. Policy documents on the topic are scrutinized and related to a concrete praxis. Data has been collected through two case studies; one carried out in Ronneby and one in Trandared, Borås. These cases where chosen because of the existence of a local policy for library skills and information search for 6 to 12-year-olds.
