Zero knowledge protocols is a lesser known type of protocol that can be used for identification. These protocols are especially designed not to reveal any information during an identification process that can be misused later on, neither by the one who should be convinced of the identity of the user, nor by anyone else that is eavesdropping. Many of these protocols are also especially designed for implementation in smart cards. The more common type of card with a magnetic stripe has during the last few years become more susceptible to attacks since they are easily copied. Smart cards combined with a secure identification protocol has been predicted to be the solution to this problem.

Denna uppsats kommer övergripande beskriva fenomenet tystnadskod inom specifikt den svenska polisen. För att kunna göra detta måste bakomliggande faktorer så som det kollegiala kollektivets betydelse inom polisen först beskrivas liksom vissa organisationsinterna motsättningar som gett upphov till tystnadskoden. Uppsatsen kommer även med hjälp av utkast från bland annat nyhetsmedier belysa hur denna tystnadskod yttrat sig i praktiken och vilka följder detta fått. Tystnadskoden är ett fenomen som har skapats ur det kollegiala kollektivet och fyller till viss del funktion som social kontroll inom kollektivet. Men också rättsligt.

The purpose of this study was to do a narrative survey of the discussion about violence in partner relationships that is held in research literature. The question at issue was: How do research literature discuss violence in partner relationships, with focus on heterosexual relationships? The eight primary documents that have been chosen are written by researchers, professional therapists, National Counsil for Women's protection (Nationellt Råd för Kvinnofrid, NRK) and Swedish Government Official Report (Statens Offentliga Utredningar, SOU). To investigate the theories, discover the similarities and differences between them and how they can complement each other, the documents statements has been analyzed with a dialectic-hermeneutic approach and social constructionism and discourse theory.The research findings showed that the gender perspective theory, the psychodynamic theory and the social psychology theory have a few things in common, but that they on the whole are different and contradict each other. The gender perspective theory dominates the discussion but needs to be combined with the other theories to give a more all-embracing understanding.

The cost for forestry logistics in Sweden is about 25 percent of the total cost of getting the raw material to industry (Anon., 2010). There might be much to gain by taking a look at your supply chains on the logistic side in your company. In this report the logistic chains by Mellanskog for ENA Energi AB in Enköping has been looked in to.

The purpose of the research is to find out how the teacher of the pre-school looks at the value of the nature Pre-school. To get an understanding of what the nature pre-school enviorment can bring, we are talking about learning, knowledge, and experience combined with the everyday lessons learned from the natural world. The research is a stepping stone on the pre-school teacher?s thoughts and reflections of what a nature pre-school is. This is grounded in a view of how having options for alternative schools lead to wider research, and all conclusions where formed after multiple interviews and analysis.The results showed that the teachers involved are very positive to the nature pre-school environment and learning process.

BAKGRUND: Omvårdnad skall bedrivas holistiskt enligt International code of etics (ICN) trots detta bedrivs den till viss del naturvetenskapligt med fokus på den medicinska delen, som i sig är viktig. Tydliga riktlinjer för andlig omvårdnad saknas och forskningen är begränsad. SYFTE: Syftet med denna studie var att utifrån aktuell omvårdnadsforskning beskriva faktorer som påverkar sjuksköterskors bemötande av frågor med existentiellt innehåll. METOD: Systematiskt litteraturstudie där sju artiklar och en avhandling ingick vilka var etiskt granskade. RESULTAT: Fyra kategorier identifierades, adekvat kompetens, tillåtande vårdmiljö, holistisk människosyn och reduktionistisk människosyn.

In this study, we have considered the impact the organization`s implementation of its vision of the psychosocial work enviroment has been for the relations between the employees. We have primarily relied on a hermeneutic approach to understand our empirical data, and when we have interpreted and made a socialpsycological analysis on our collected empirical data. We have used Smith´s Institutional Ethnography, Sheff`s Social bonds and Asplund`s theory of Social responsivity. To collect the empirical data we have combined quantitative and qualtitative methods and a textanalysis at a visiondocument in the aim of capture both the depht and the breadth of our chosen fields of study. The results we have found shows that the psycosocial work environment within the organization can be seen as interplay between individual and enviroment and between individuals as well and that this interaction is influenced by the organizational culture that is created by the organization`s political vision.

Purpose: This thesis aims to study how students in upper secondary school evaluate sources in their everyday school work and how the role of the school library and librarian officiate in this context.Methodology: A web questionnaire was conducted and 155 students from different schools, with or without school library and school librarian, participated. We coded and aggregated the questionnaires according to the strategies that are used when evaluating sources, identified by Francke, Sundin and Limberg. Cognitive authority, a theory by Patrick Wilson, was also a part of our analysis. Conclusions: The study shows that students use different strategies, separately or combined, as a way to evaluate sources. The teacher is regarded as a cognitive authority and is the main influence concerning source evaluation. It also shows that the role of school libraries and school librarians, in this context, seem to be non-existent.

The main question this bachelor thesis aims to answer is how the public service program Tg1?s news broadcasts may look. The following questions were used to discuss thetendencies of the result: How can the distribution of the news categories appear in Tg1?sbroadcasts? Can the main news be considered as impartial and objective in its linguisticand pictorial representation?To answer the aforementioned question I chose to do a combined study, using aquantitative content analysis and a qualitative content analysis.To lead my research, I focused on two requirements underlined by public servicebroadcasters, namely, objectivity and impartiality, and diversity. The outcome shows thatthe diversity in Tg1?s broadcast is disproportionate and that the pictorial representation isnot impartial and objective without the linguistic part.

The Swedish energy company Vattenfall is currently the owner of the district heatingsystems in Nyköping and Motala. To be able to also offer cooling solutions tocustomers are becoming more and more important. This report describes the resultsof an investigation of the cooling market in the two cities and the potential needs forcooling today and in the coming 20 years. The total potential for the coming 20 yearsis estimated to be roughly 17 MW for Nyköping and 9 MW for Motala.Two possible district cooling systems for each of the two city centers was modeledand a comparison was made between different cooling techniques namely absorptionand compressor chillers.Absorption chillers driven with district heating during the summer is one way ofincreasing the load in a combined heat and power plant and thereby the possibleelectricity generation. The cost of heat production must be low for absorption chillerto be able to compete as an alternative.
