Dokumentet är ett resultat av studier gjorda under kursen Kandidatarbete I Datavetenskap. Arbetet utforskade, genom fallstudie, två egenskaper av distribuerade informationssystem och relation mellan dessa: säkerhet och prestanda. Målet med fallstudien har varit att belysa nackdelen med användning av Secure Socker Layer (SSL) dvs. dess effekt på hastigheten och fördelen med SSL, dvs. SSL:s roll i informationssäkerhetsarbetet.

The study shows the current need for security solutions concerning work with information in different areas.Investigations will show important solutions for printers? needs to meet the increasingly harder demands forfast and safe digital communications. Important factors to be analyzed in the investigations are: access todifferent types of information, workers authority of information, access to the data base register internallyand externally, production solutions for an effective fault detection and data base solutions fororders and distribution.Planned and unplanned stops result in a standard of value in interruptions. Internal data bases areprotected by so-called ?Fire Walls?, ?Watch Dogs? and Virtual Private Networks.

The new information society has revolutionised almost the entire world. But the new technique does not only bring good. That which was before only available on paper may today only be available on a computer system. This makes it possible to send data electronically. In the wrong hands that information can become a threat against the security of an individual, a company or even a nation.

The housing estates in the outskirts of Sandviken, consist of relatively large scale apartment buildings. This report, that is a B.A. thesis at 10 Swedish university points, aims to investigate and describe the opportunities to improve safety and security for inhabitants in Norra Björksätra. The purpose with this report is to make Norra Björksätra to a more attractive place to live in, by changing the negative trends in the area. Since demolition of at least some of the houses could be of current interest in some years; the purpose is also to investigate whether demolition or renewal of the area is the best solution.

Today many different types of lock systems are used all over the world. Passwords, finger prints and magnetic strips are a few examples. When the key is a three dimensional object, lika a physical metal key, the security depends, in a high degree, on that you can?t copy the object without access to it. One approach to copying the object is photographing the object, and from these photographs create a copy.

The present study sought to examine the collaborative role of the student organization Here 4 U and the impact of this collaboration on the organization and its partners. As a point of departure a questionnaire was distributed to supervisors, principals and other cooperation partners of Here 4 U, the most prominent quantitative results of which were related to previous research, new institutional theory and empowerment theory. It turned out that partners interacting with Here 4 U felt that the collaboration was necessary and wanted to continue with it. The respondents to the questionnaire were asked to define the concept of collaboration. Factors emphasized by respondents included feeling of community, security, and common goals.

Cambodia, in Southeast Asia, has tropical monsoonal climate with distinct dry and rain seasons. Many people are poor and live in rural areas. Farmers mainly culture rice, and raise pigs, cattle and poultry as well. During two months, a minor field study was performed in Cambodia. The main purpose was to evaluate the impact of contributions done by projects that started in 2005 and were managed by the local organization CelAgrid.

The world is increasingly coalescing, ecologically, economically and culturally. Many problems can no longer be solved within the own state borders and the limitation of the territorial state is obvious. Jürgen Habermas means that a world domestic politic without a world government is what this progress need. Therefore it is important that national interests become less central and the solidarity between people is given priority in international relations. The focus of this thesis is therefore a critical discourse analysis of the current position of the internationalisation of Swedish security and defence policy.

Since the 9/11-attacks several nations have been confronted with a new international threat, its nature traces back to the political- and religious- radical movements of the 20th century Cold War. Ever since, various states have been under threat by terrorist organizations around the world due to mainly participating in worldwide counter-terrorist interventions created by western alliances. In Sweden, amongst other countries, the state took security-precautions that would imply total control of information throughout the territorial borders. The assigned proposition was accepted by the Swedish parliament in June 18th 2008, after this date wild spread criticism was still in effect ever since the Swedish government first publicly announced the proposition in May 8th 2007. This study emphasizes on understanding why the Swedish government chose to present this proposition to parliament, in order to complete this task the study will present the motives and the alleged threats that were the core of the proposition and its value-maximizing goal of creating a new surface for Swedish homeland security.

The purpose of this qualitative interview study was to examine which approach experienced pre-school teachers have on children that seek negative attention. The study contains five informants in a city in the middle of Sweden and they all have at least 10 years of experience after their diploma from a pre-school teachers? program. The questions I aimed to answer were the following: How did the pre-school teachers define the expression ?negative attention?? What approach did they have on children that seek negative attention? What effects do the childrens? seeking of negative attention generate on their self-esteem and sense of security? How possible do the pre-school teachers feel it is to achieve the goals of the pre-schools? curricula that every child should get their needs respected and met, when they work with children that seek negative attention? The results showed that the teachers think of them as resources in the group and that they need to think of the environment around these children both at home and at the pre-school to better meet their needs.

The aim of this essay is to investigate how national and international guidelines relate to library services to prisoners in Sweden and to further illuminate this through a comparison with some examples from a few European countries. The essay examines what rights to library services Swedish prisoners are given in law, what national and international guidelines say, what demands are placed on the librarian in the form of education and suitability, what economical resources exist to realise library services to prisoners, what measures are taken to provide for language minorities, and how the security aspect is handled when it comes to computers and information technologies. The information has been obtained through interviews as well as through studies of books, articles and conference proceedings. The essay includes a small case study of how library services are provided for prisoners in Haparanda. Findings point to a gap between the goals that are presented in national and international guidelines and how the library services to prisoners function in reality..
