This user study was carried out at the library at Chalmers University of Technology in Gothenburg in the spring of 1999. Chalmers wanted to investigate how much their employees use electronic journals. To facilitate decision-making and be cost effective, the library needed to know about their customers' opinions. The main purpose was to investigate the usage of electronic journals, how the library's choice of these journals affects the frequency of use and what the attitudes towards them are. A questionnaire was sent out to 2 400 employees; 477 replies were received.

As the information society becomes increasingly flooded with digital images, the need for efficient image retrieval systems increases as well. To handle the vast amounts of data involved, the indexing process needs to be run automatically, using content-based descriptors extracted directly from the digital image, such as colour composition, shape and texture features. These content-based image retrieval systems are often slow and cumbersome, and can appear confusing to an ordinary user who does not understand the underlying mechanisms. One step towards more efficient and user-friendly retrieval systems might be to adjust the weight placed on various descriptors depending on which image category is being searched for. The results of this thesis show that certain categories of digital images would benefit from having extra weight assigned to colour, texture or shape features when searching for images of that category..

The purpose of this thesis is to investigate the library for children and young people at Sahlgrenska university hospital in Sweden from a salutogenic perspective. The sociologist Aaron Antonovsky states that human health is benefited by the salutogenic perspective, since it stimulates our sense ofcoherence.The theoretical departure point is sense-making theory. The theory states that in order to move through life, humans are dependent on a sensemaking process. To make sense of our current situation, we need information. What kind of information depends on the individual and its context.

The emphasize of this study is to evaluate security issues for home users having a personal computer connected to the Internet. It focus on the usage of advantages and disadvantages when using a firewall while connected to the Internet. The hypothesis is that it gives a better protection to install and use a firewall compared not to do so, due to security flaws in the operating system. The prediction was tested on a home user's personal computer. The testwork was divided into two major tests, each of them performed with, respectively without, a firewall. These major tests were divided into five smaller semi­ tests. The first semi­test without a firewall suffered from a virus or worm attack resulting in loss of data and log files.

This study examines use and users of information and records originating in the context of a contemporary police organisation. This area of research has only been of focus for a relatively few researchers. This in contrast to use and users of historical archives which has been in centre for more studies. The study is conducted with a quantitative method structuring data from 120 selected registered matters containing user queries. The research questions addressed are:- what user categories use the records of the authority- which are the ways of contacting the authority preferred by the users- which are the identifiers provided by the users and how well are they matched by the search artefacts available to the staff of the authority- what information and records are sought-after by the users.For comparing the identifiers provided to the search artefacts has been selected the two most frequently used registry systems within the authority.

Styr is a computer program that the construction company NCC use in their construction projects. The program is used to keep the economy of their projects in a good order and things for the best in an early phase. The problem is a low extent of utilization. During the latest decade NCC has put a lot of job and money trying to develop the program. The question is how to get the employees to use the program in a greater extent.

The aim of this thesis is to examine the Swedish public libraries acquisition processes when it comes to fiction for adults. The thesis focus on how the librarians responsible for acquiring view literary quality when they manage their collections and how their views coincide with that of the user?s explicit wishes. Furthermore this thesis looks at the librarians reading habits and how they coincide with that of their perceived users.The study uses literature pedagogic perspective theory to see how the librarians look at fiction and what they value in it. In order to get answers six librarians have been interviewed in this study that uses a qualitative approach to getting answers.

The aim of this thesis is to study how public libraries in Sweden use alternative shelf arrangements that differ from the library?s original classification system, which in Swedish public libraries usually is the SAB-system. I sent out a survey to 169 public libraries, where I received 114 replies. 77 of these stated that they had some kind of alternative shelf arrangement, therefore these are the ones that are included in my study. I wanted to investigate in what way the libraries had changed their shelf arrangement and why this decision was made.

[ An abstract in English will follow]Denna uppsats handlar om på vilket sätt användarinvolvering påverkar acceptansen av ett affärssystem. I studien redogörs varför acceptansen påverkas av användarinvolveringen, samt hur påverkan sker och vad som leder till den.IT genomsyrar idag så gott som alla former av företagsamhet. Affärssystem stödjer affärsprocesser i flera branscher, från tillverkande företag till renodlade tjänsteföretag. Ett företag behöver exempelvis anpassa både sina affärsprocesser och det nya affärssystem för allt som sker inom företaget. På grund av komplexiteten som detta för med sig är implementeringen ofta ett stort steg för företaget och dess anställda.

The aim of this Master's thesis is to understand public library users' perceptions of librarians' attitudes to users and professional knowledge. The purpose was also to investigate the relative importance to the user of pleasant or a knowledgeable librarian. As a theoretical framework we use theory from business economy where the experience of the user is in focus. Answers were sought to the following questions: How do users perceive librarians attitudes to users? How do users perceive librarians professional knowledge? How do users want to be treated by public librarians? What kind of knowledge should public librarians have, according to users? We interviewed twelve students in university education that are users of public libraries.

Facebook is the most widely used social media in Sweden. It allows the user to easily share the latest from their everyday life, their opinions, as well as communicate with their acquaintances. According to the latest poll from the Foundation for Internet Infrastructure, 33% of teenagers in the ages 12-15 spend their Internet time being active on social media. 63% of these teenagers visit Facebook on daily basis.Herein, we examined how Facebook can be exploited as a complement to the education of the mother tongue. The investigation was performed with a questionnaire as well as a test group that has been supplemented with semi-structured interviews. In conclusion, the study showed promising results in the usage of Facebook with the education.

In this Bachelor Thesis (20 p.), we present the history and development of "Intelligent Houses", and most important- explore some of the future possibilities in this area. The project has been carried out through an interdisciplinary cooperation between three different educations at the Blekinge Institute of Technology. By conducting a dialogue with various actors with different professions, we have been trying to identify needs within the concept of "Intelligent Houses", were the end user is not only the tenant or homeowner. Through Participatory Design methods, such as a Future Workshop, we have brought the users together to discuss their own and each others needs and hindrances in their respective work practice, and how intelligent house technology could improve their work conditions. We have also been testing a highly sophisticated CO/CO2/Moisture/Temperature/Enthalpy multi-sensor & controller, originally developed for regulating indoor climate systems. Based on the needs we have found in our fieldwork, we have been looking at possibilities to make multi user solutions with the sensor..

Location-based services (LBS) contains of services helping users of finding positions of themselves or other objects. LBS applications can present information in varies types of ways, these could be threw speech, text, geographic symbols, photos etc. Not many studies have been done to examine the aspects of LBS communication and there is a demand for user and context centered mapping.The purpose of this report is to present a model for the development of user and context based services. The model will give guide lines of recommendations when implementing LBS. The different technologies that support LBS will also be noticed.

In this project a simulator has been developed (in C++) with the purpose of illustrating how changes in environmental regulations, tax levels and other policy measures affect the composition of an energy system. The aim of the project was to investigate how energy companies? investment strategies are affected when changes in economic and environmental conditions occur. A standard scenario has been created based on current Swedish conditions, but the user can create new scenarios and set parameters freely. The user is tasked with building power plants to supply the city/region with district heating and electricity during a pre-set number of years. When the simulation is finished the result is graded in the following categories: economy, environment and quality. To evaluate the simulator three scenarios were created (?early 20th century?, ?reduced environmental control? and ?future?) in addition to the standard scenario and these were compared with each other by examining how a select group of power plants perform under the given conditions.
