In the future network-based Swedish Defence (NBD), attaining information superiority will be of great importance. This will be achieved by a network of networks where decision-makers, information- and weapon-systems are linked together. As a part of the development of NBD, we have performed a study of user interface design for a future network-based tool package for analysis of sensor systems, referred to as the C2SR-system. This thesis was performed at Ericsson Microwave Systems AB, Sensor and Information Networks, during the autumn 2002. A pre-study concerning the requirements of usability, trustworthiness and functionality of a user interface for the C2SR-system was performed.

The purpose of this Masters thesis is to investigate how actors involved in a municipal's adult education view students access to information- and library resources. The adult education in the municipal is on contract which means that there are several different actors involved in the realization of the adult education. The raised questions in this study deals with; libraries role within adult education, students needs for becoming information literate and where responsibilities for students access to libraries lies. We used a qualitative method which includes interviews with two principles, a controller, three pedagogues and a librarian. The empirical data is analysed against taxonomies and categories which originates from the theories of David Loertscher and Christine Bruce.

The aim of this thesis is to examine Social science teachers infor-mation seeking in their professional role.The focus in this study has been on what sources the teachers use for information seeking, examine and analyze their information practices and how they state their reasons for using different in-formation sources, and finally how these teachers experience con-ditions related to information seeking and how these conditions in-fluence their information seeking.This study is based on four semi structured qualitative interviews. The empirical material from the interviews has been compared to earlier relevant research and analyzed with a theoretical frame-work, which includes conceptions from a sociocultural perspec-tive, a matrix over different kinds of information sources devel-oped by Höglund och Persson and McKenzie?s model of infor-mation practices.The results of this study are:- These teachers use both formal and informal sources and external and internal sources. Digital sources are important and these have consequently been added to Höglund och Persson?s original matrix from 1985.- Information practices tend to overlap each other, for example ac-tive seeking (more specific and prepared information seeking) and active scanning (less specific), which are the two most common information practices among the teachers.

Det här arbetet behandlar ämnet EDI (Electronic Data Interchange). EDI är en teknik som gör det möjligt för företag att utbyta affärsinformation elektroniskt, i stället för att använda den traditionella pappershanteringen. EDI ersätter normala pappersdokument med elektroniska filer, som gör det möjligt för olika företags datorsystem som är sammankopplade, att kommunicera med varandra utan mänsklig inblandning.I arbetet har en undersökning genomförts med utgångspunkt på EDI och mindre företag. Anledningen till att jag inriktat mig på mindre företag är för att jag anser att dessa har en annan syn på investeringar och satsningar på ny teknik än vad de stora företagen har. De frågeställningar som jag har undersökt är hur stor utbredningen av EDI-användningen är bland mindre företag, anledningar till att mindre företag tvekar med att införa EDI.

That the Swedish society looks different depending on the location is a fact and that in turn means different schools with different conditions and resources depending on the localization. We have in this study interviewed four teachers in a high-status school and four teachers at a low-status school in a municipality south of Stockholm. The purpose of our study is to find out how teachers / educators perceive children's physical and psychological safety in their workplaces, and if there is a difference between the schools in resource allocation.In order to answer our purpose of the study, we chose to interview teachers about how the school looks for the kids in order of enough resources such as books for all, enough facilities and competent and even skilled teachers. To take into account and consider people´s backgrounds, experiences, and cultural frames of reference is a way to interact within a respectful world, and as a good approach to educating children from all parts of the world and with all the different mental and physical difficulties. The two schools in our study show lack of resources but of different kinds.

Kitron had wishes to be able to test and measure how disturbance affects their vehicle electronic units before they have been verified by SP Technical Research Institute of Sweden in Borås. This work started with the writing of a demand specification together with Kitron for a product PSQS, Power Supply Quality Simulator, which can generate some test pulses according to a standard for electronic units to Volvos vehicles. A design proposal was developed with the help the demand specification and was verified with the help of simulations. All electric schematics was designed with the guide of the design proposal. The pulses realized in the works of this thesis are those which Kitron experienced that they have a need to test in their own premises and which are possible to generate with the means available.

The aim of the thesis is to present a study of what works well and what does not work so well in today?s use of computers in primary care with a special focus on the use of computers in the management of referrals for consultation. In May 2009 a module for electronic consultation referrals was introduced in the computer system Cosmic at the University Hospital in Uppsala. Previously, the primary care units had to use two different systems for management of referrals. Referrals sent internally within primary care have been sent electronically while referrals to the University Hospital or other external units were sent on paper.

The aim of this study was to examine the aspect of power in the relationship between the personal assistant and the disabled person he or she works with (the user). The study was based on interviews with five personal assistants who worked for private companies that provided personal assistance. Seven themes were identified and discussed. These were: the users amount of control over the assistance given, the workplace environment, the working conditions, the organization of personal assistance by private companies, the assistants recourses and usage of power and the users participation in chores. To analyze these themes I used Foucault's theory of power and the perspective of Human Resource.

Title:Comparison of databases ? Is the law an obstacle?Authors:Alexander Ankarberg, Applied Information Science.Tutors:Lars- Eric LjungProblem: Cross running databases is getting more and more significant during the development of the information flow. There are huge benefits if we start to use the technique that already exists. The law is today an obstacle, so what would happen if the law wasn?t so stern.

The purpose of this thesis is to analyse studies that evaluate Web search engines. This is done in four categories; the researchers? purpose, the evaluation measurements, the relevance, and the time aspect. Our method is based on a text analysis in which we use the direction of analysis of the content of sixteen evaluation experiments. Our results indicate fundamental differences in the way the researchers are tackling the problem of evaluation of Web search engines.

The economic growth we have experienced the last century is based on limited natural resources. Whether these resources will last for a further economic growth is widely debated. Pessimism and optimism have each been influential philosophies in debate whose opinions can be conceded as two opposing opinions. In this paper we have analyze these opinions from an economics perspective. To study this further, the construction and meaning of the pessimistic and optimistic arguments have been applied implicitly on the Leontief production function and the Solow growth model.

The purpose of this thesis is to draw a picture of pedagogical work at the senior level with a critical perspective of information and media. As a method for gathering material for the analysis, a case study was made with qualitative interviews together with documents that describe the case. Relevant literature for the subject has been used as an introduction and as a theoretical basis. The literature concerns subjects such as a childrens relation to media, the schools intructions, the role of the school library and some theories regarding learning. The conclusion is that the respondents focus on conversations and reflection regarding the sources of information and its use, and that the childrens adaption of the material is an important factor in teaching.

Bakgrund: Personer som använder Internet kan bli övervakade och profilerade av bland annat spionprogram och cookies på webbsidor. Dessa spion-program och dolda filer kan samla ihop information om användaren som skickas tillbaka till sändaren. Detta sker ofta utan användarens vetskap. Företag som placerar spionprogram i fildelningsprogram har syftet att samla information för att sedan rikta reklam till privatpersoner. Den information som kommer tillbaka kan säljas vidare i undersökande syfte för reklam till en tredje part.

This thesis will address a problem concerning availability of information systems at an enterprise within the financial sector and its external suppliers, so called trusted third party. The information system resides on the internal network of the enterprise and must be available to both employees of the enterprise and the trusted third party simultaneously. This contradicts the company policy which disallows third parties access to the internal network. The HAVECA-model introduced in this thesis provides a framework of methods, each solving a sub problem identified in the model. The identified methods are hardening, verification, control and assurance, together supplying a method for continuously securing the internal network against a trusted third party.

This thesis aims at examining to what extent a few, algorithmically very easily extractable document features can be used to classify electronic documents according to genre. A set of experiments is therefore carried out, using only 11 such simple features in an attempt to classify 84 documents belonging to electronic academic journals into three manually identified genres: table of contents, article, and review. The 11 features are also divided into three sets, containing metrics of words and sentences; punctuation marks; and URL links, respectively. The performance when using these sets of features is then measured with regard to classification accuracy, using a k-NN classifier, four different values of k (1, 3, 5, 7), and both leave-one-out and 10-fold cross-validation. Best results are achieved when using all three feature sets (i.e.
