The purpose of this Master's thesis is to study metadata and its use at Web sites of six Swedish universities and colleges. Each Web site has been examined at three different hierarchical levels and the total number of examined Web pages is 258. 16 questionnaires have also been sent to webmasters at the six universities and colleges. The results show that metadata refers to the data which can assist to organize, describe, identify, locate, evaluate and retrieve resources on the Internet. Even though there are several different metadata formats available on the Internet, the commercial search engines only support the HTML's title tag and the meta tags with the attributes keywords and description.

The object of this study is to examine the effective functionality of an OPAC-system while a few participants interacted with the catalogue. I?ve used Carl Martin Allwood?s (1998) four designed usability factors to be able to estimate the effective functionality of the online catalogue. Theoretic basis is Human Computer Interaction together with Allwood?s four defined usability factors.

This thesis deals with subject-based hierarchical search-services on the World Wide Web. The purpose is to investigate how systems of this kind facilitate information retrieval through subject-based information seeking. Its starting point is taken from the study of texts and qualitative analyses of search-services on the World Wide Web. Important aspects and features of the Internet and the World Wide Web are explained as well. Three systems are examined: Mölndals Stadsbiblioteks Länkkatalog, Svesök, and Alta Vista.

The aim of this thesis is to examine the possibilities and challenges facing an archive, Svenskt barnbildarkiv (SBBA), if to publish its material online. Our context for this study is image indexing. Our main questions are: How can SBBA index their pictures for a possible publication on the Internet? Are there any pros or cons in the determination of topics in children?s images, and in that case, which? What search paths are important when indexing children?s pictures, and why are they important? To answer these questions, the thesis is built on a wide study of interdisciplinary literature. But also on SBBA: s own handbook for image ?registration?, and on interviews with the persons working at the archive SBBA, in Eskilstuna.

The purpose of this study is to describe how dandelion children has experienced their childhood and how their childhood has formed them in their adulthood. The purpose is also to examine how the attachment between the child and the parents has come to expression. To search for the answers of the purpose the following issues has been created: How do dandelion children experience that their upbringing has formed them as a human being in adulthood? and How do dandelion children experience the attachment to their parents have been expressed during childhood? The empirical material of this study is based on a qualitative approach where the material has been assembled by semi-structured interviews with five respondents. The result shows that all the respondents has experienced their childhood as a problematic existence due to their parents lacking in their basic care of the child.

Declining levels of estrogen at menopause could be a contribution factor. Isoflavones is a vegetable substance, with structural and functional similarities to the human estrogen. This is a potential reason for possible cholesterol-lowering effects.

This Masters thesis deals with query expansion in an online library catalogue. The aim of the study was to compare the retrieval effectiveness of four different query types when applied to the online library catalogue of the University College of Borås. The query types were: an initial query, the initial query with right hand truncation, the initial query expanded with synonyms and finally the initial query expanded with synonyms and right hand truncation. 24 topics were formulated, and four queries for each topic were constructed. The records retrieved by the searches were judged with regard to topicality, and were judged to be non-relevant, partially relevant or relevant.

The purpose with this study was to systematically examine scientific studies of audiologic group rehabilitation. The definition of audiological rehabilitation was explored, different variables that influence the result and how the outcome measures should be done and its relationship with the goals of audiologic rehabilitation. The method used was a literature study. Pubmed and Cinahl were used for the search of literature. Some articles were searched from scientific studies reference lists and also advice from the supervisor.The result from the different studies shows that the effect of rehabilitation varies as there are many aspects that have an affect on the outcome measure.

The aim of this study was to describe the mental and social causes to obesity among children and adolescents, their consequences and what preventive interventions that are used. The method used by the authors was to search for scientific articles in the database Medline, using the keywords: obesity, overweight, child, body image, social, family, school, depression, nursing, quality of life, social support, prevention and support. The study was performed as a literature review, with a descriptive design, and the result contained 22 scientific articles. The main result of this study showed that obesity among children and adolescents is not only an individual problem, it affects the whole family. The main causes to obesity among children and adolescents are the socioeconomic status of the family, their lifestyle, and even gender to a certain degree.

Background: More focus has been placed towards autonomy when it comes to care and in special towards palliative care. The purpose with palliative care is to relieve and support at the end of the life. When the patient has difficulties to communicate to those around him due to his illness it is hard to preserve the patients right of self-determination. It is very important to consider the patient as autonomous during the course of the illness. Different alternatives have been developed to preserve the patient?s autonomy such as dedicate a deputy or plan the care of the patient in advance.Aim: The aim of this study was to describe, from an ethical point of view, how the patient?s autonomy could preserved at palliative care.Method: A general literature study where 11 scientific articles have been analysed from a qualitative checklist whereof the result has been discussed based on the principles of ethics.

This thesis shows the result from investigations of methods that use distance vectors when matching pictures. The distance vectors are available in a distance map made by the Euclidean Distance Transform. The investigated methods use the two characteristic features of the distance vector when matching pictures, length and direction. The length of the vector is used to calculate a value of how good a match is and the direction of the vector is used to predict a transformation to get a better match. The results shows that the number of calculation steps that are used during a search can be reduced compared to matching methods that only uses the distance during the matching..

This is a heuristic evaluation of Umeå university library?s Online Public Access Catalog (OPAC). It makes use of four of Nielsen?s ten heuristics, flexibility and efficiency to use, match between the system and real world, visibility of system status, and aesthetic and minimalist design. The evaluation was done by having 3 evaluators inspect the interface individually, as per Nielsen?s (1990) recommendation of 3-5 evaluators.

In the Swedish school library discussion, the most prominent role of the school library haslong been that of cultural centre in the school, with the main goal being to encourage children'sreading. During the 90ies there were signs of a shift in focus to the role of information centre,giving active support across the whole range of the curriculum, in the independent researchingwork of the students. At the same time severe budget cuts caused great worries for the future.The interest for the school library media centres increased during this time, many differentorganizations said they wanted to fight for better school libraries. The purpose of the presentwork was to find out who they are, what they want and what their ideal school library lookslike. Fourteen organizations were studied, focus was on activities during 1995.

The purpose of this study is to examine if digital public libraries are serendipitous environments. Serendipity in this instance is defined as finding something unexpected and valuable, while searching for something else.A survey was conducted at two Swedish digital public libraries, where the patrons were asked to fill in a questionnaire online. The questions were based on the work on serendipitous digital environments by Lori McCay-Peet, as well as considerations of human factors that could possibly influence serendipity.The result indicate that a majority of patrons experience serendipity at the digital library, although it?s still more common to do so at the physical library or on other web sites. The result also confirms the importance of taking human factors into account when studying serendipity.
