The aim of this thesis is to study a number of standards and theories, from the two research areas human-computer interaction and psychology, about how a graphical user interface (GUI) should be composed in order to facilitate interaction between humans and computers. Special emphasis is put on how the GUI should take into consideration the strengths and limitations of human cognition and perception. A study of three web catalogues shows how these theories appear when concretised. The following questions are answered in this thesis:What guidelines and styleguides can be found that specify the design of a user-friendly GUI?How do a few library catalogues on the web match a selection of these design principles?The guidelines are extracted from literature concerning human-computer interaction, psychology, automated library systems and web design.

This is a study in the field of Music Information Retrieval (MIR) concerning classification of musicgenre. The study uses a music listening experiment and machine learning methods to determinewhether or not the drum sounds from different songs contain sufficient information to classifygenre.MIR methods are used to extract data from the audio signals. The data is used together with theclassification results of the listening experiment to train different machine learning algorithms toclassify the songs in different genres.The results indicate that using only drum sounds for genre classifications works well, both forlisteners and for machine learning methods..

As a student during my studies, I have been told about entrepreneurs who have red numbers in their financial statements, and there is a forest machine operator shortage in Sweden. The basic idea of this thesis was to examine the underlying factors that may have caused the problems described above. The aim of this thesis was to investigate the factors that create stress and job satisfaction as a forest machine operator. The study was performed as a comparison between forest companies own harvesting teams and entrepreneur teams to investigate if there are any differences in stress and job satisfaction between the two different types of team. The study was conducted in collaboration with SCA Skog. The material for this study was collected by doing interviews with SCA's harvesting teams. A total of 27 forest machine operators were interviewed, divided into a total of 10 separate harvesting teams. It was very similar between the different type of teams, which situations the operators experienced stress.

In this study we have examined in which way the horse is used in Equine Assisted Therapy, and what effects the treatment staff experience and describes that the interaction with horses has on girls who self-harms. Our Empirical data was collected through qualitative methods such as interviews, participant observation and informal interviews with a total of six different informants, from five different activities with Equine Assisted Therapy for girls who self-harms. In the analysis we have assumed symbolic interactionism, a theory focusing on the human as a social being, where the self-image alters in the social interaction with other human beings. We interwove this theory with the Biophilia hypothesis, an explanatory model concerning human?s relationship to animals and nature.The conclusions we have found in the results are:Equine Assisted Therapy is a complementary treatment comprises both horseback riding and exercises which is not based on the horsebackEquine Assisted Therapy almost always involves three parts, the therapist, the client and the horse.

This is a study about the communication interaction in the context of the reference work at some public university-libraries and some private company libraries in Gothenburg and Borås. The primary purpose of the study is to investigate the communication interaction in a library situation. The second purpose is to deepen the knowledge, understanding and to establish what is important in this communication. Focus has been on how the intermediaries communicate and how she or he perceives this communication. The intermediary needs to manage the communication with all the different patrons and different information needs of the patrons.

The aim of this study is to better understand the Swedish concept of ?förebyggande socialt arbete?, preventive social work. I have conducted eleven qualitative interviews with different key persons and skaters, together with participant observation. During the process of analyzing the material I have used Randall Collins´ concepts of interaction ritual chains together with Jean Laves and Etienne Wengers concept of situated learning. The answers could be split up in three areas, first those who regard prevention work as building good things for the future.

This study presents an alternate viewpoint to the strive to overcome the gap between research and practitioners within paper prototyping in interaction design. Earlier research identifies three aspects of this gap, which is:Practitioners being unaware of interaction design methods and theoriesPractitioners being aware, but choosing not to apply these methods and theories, due to time, budget and constraints of labourPractitioners and research having different perspective on similar design issuesOur study was done by carrying out qualitative interviews with interaction designers based on two digital design bureaus. One of the bureaus has an expressed link to research: the other has not. Our hypothesis is that the gap would manifest as a difference in work practice between the two bureaus.Our study shows that the two bureaus have similarities in work practice and that this work practice is based on scientific methods and theories, but is adapted to fit the client and/or the project. We conclude that the overcoming of the gap might not be necessary.

Föreliggande studie bygger på kvalitativa intervjuer av fem pedagoger. Genom att intervjua pedagoger med utbildning i Human Dynamics, undersöker jag hur pedagoger arbetar praktisk med Human Dynamics med fokus på inlärningsprocessen. Jag undersöker även likheter och skillnader mellan Human Dynamics och Dunn och Dunns lärstilsmodell..

Forest ebeaver is, equipped as a bio-energy harvester, approximately four and a half meter long and weigh just over two tons. The main purpose of this report is to find out whether a small machine like Forest ebeaver can be profitable used in early thinning. To find this out a study has been made using the machine to thin in a young pine stand..

The project was carried out with SwedSafe AB, engaged in hearing and manufacture of earplugs. Since the company is a world leader in the sale of these products, it is important that they keep a higher level of quality of these products.Production of earplugs is currently a automated manufacturing process that is divided into four conveyor belts and one of the conveyor belts is what will be affected in the project. The belt affected during this process is exposed to various elements such as filling, closing, fermentation and extraction of products. Because the belt gets dirty, degraded products and the work environment is affected. To increase the quality of products and improve the working environment requires an automatic cleaning process, which collects dirt from the belt.The aim of the project is to design a machine that prevents the belt from becoming dirty, preserve molds clean and improve the working environment without disrupting production.

Reporting harvested and forwarded volumes are important for the forest industry as it provides information of the size of the stock and facilitates logistics. Figures from Holmen Skog show low reporting frequency. The purpose of this study is to investigate the reason and find suggestions for improvement. A total of 17 machine operators were interviewed using a questionnaire combined with open questions. The results show that the majority of the machine operators find it simple to use the reporting system, although, some of them reports that it doesn?t always work as supposed to.

The purpose of the study is to investigate methods and work procedures that aim to motivate people to leave a cult and/or supporting them after a cult exit. The study was limited to investigate how Sweden?s, within the area, three premier voluntary organizations Föreningen Rädda Individen, Rådgivning Om Sekter and Hjälpkällan work with present -, ex ? and relatives to cult members. In addition to the mentioned organizations we have also investigated the work procedures and methods used by Åke Wiman. The study has got a qualitative approach and includes semi-structured interviews.

The scarcity of qualified forest machine operators as well as the increased competition for competent machine operators among others from the mining industry in Norrland, were the reasons to investigate what attracts and what deters active and potential forest machine operators to the occupation. An interview study was conducted among four groups with four persons in each group. The groups were students in year 1 and 3 respectively at a forestry school at upper secondary school level as well as employees of a forest company and employees of contractors. The majority of all respondents were of the opinion that their interests in machines had been important for the choice of occupation. But for the active machine operators both the interest in the forest and their interest for machines have had importance for choosing this occupation.

Viewer interaction is a common part of live broadcasts on the web and enables production and viewer to communicate with each other. The possibilities in viewer interaction make it easier for productions to create viewer engagement by involving them in the live broadcast through chats and social media. In creating a bond between production and viewer the interaction must be carefully managed to suit both the shows and the viewer?s needs.  A qualitative study has been used to analyze the viewer interaction in two Swedish live broadcasts on the web.

Human-animal interaction is suggested to be a main feature within livestock production. The quality of handling, for instance, appears to be greatly depending on the attitudes and behaviour of the stock people. Various studies have been conducted on relationships between human and animals, but few have looked upon differences in human-animal interaction and attitudes between countries. Two countries often discussed in livestock production are The Netherlands and Sweden. It would be of interest to compare these two countries to find out whether (assumed) differences are reflected in the attitudes between animal handlers.
