The use of insecure networks -such as the Internet- to send and receive information has made the need for preventing unauthorised people reading it yet more important. One of the easiest way to do this is through public key cryptography. However, the problem with this solution is how to tie a specific public key to a certain subject. This is solved by letting a trusted third party issue a certificate that holds, as a minimum, the name of the subject and the subject's public key along with the issuer's digital signature on the information. The rules we make for issuing, revoking and verifying of certificates and the entities that are being used to do so are called PKI - Public Key Infrastructure.

Our purpose was to shed light on how parents act in respect of providing alcohol to young people when they ask for a taste of home, or wish to bring alcohol to such a party. We used qualitative interviews and the results show that some of the respondents think that it may be acceptable to provide alcohol, while some do not. The results also show that the respondents think that parents are important as a model for the young. They could not purchase alcohol for the purpose of giving it to the young but only if alcohol is available at home. The reason for this behavior is the parents' assessment that the young person demonstrates a level of maturity for his age that they are presumed to be able to handle a small amount of alcohol.

Encounter Control är ett sammanfattande begrepp för generell styrning och kontroll av tjänsteprocesser med särskilt fokus på inslag av externa och eller interna kundinteraktioner (encounters). I dessa möten agerar kunden ofta i två olika men integrerade roller: som kund och medproducent till den efterfrågade tjänsten. Denna encounterproblematik är välkänd och men också mycket komplex. De berörda aktiviteterna inrymmer många olika problem med t.ex. mätning, analys och förbättring av både kvalitet och effektivitet.

In contemporary global environmental governance stakeholding, as a means for defining legitimate participants in democratic decision-making, has become of great importance. In this essay I deploy the concept of ?the stakeholder perspective? to denote arguments that all stakeholders ? defined as carriers of particular interests ? should be able to participate in political decision-making affecting their interests. The purpose of the essay is to analyze the stakeholder perspective's potential to change environmental politics. Departing from the philosophy of Heidegger, I develop a theoretical approach that separate the concept of the political from that of politics.

This essay analyses the act of reading August Strindberg?s novel En dåres försvarstal (A Madman?s defence). It reveals the writer?s motif and purpose with the text and it shows how a certain interpretation of the text is crucial for the writer?s intentions to become reality. But it also shows how this interpretation is threaten by several, both intertextual and extratextual, thematically and structural, factors.

What role should science play in democracy? Political scientists often assume that it is possible to demarcate between ?instrumental? and ?moral? knowledge, and argue that citizens and/or politicians should use their moral knowledge to agree upon political goals and then apply the instrumental knowledge of scientists to achieve them. This straightforward view is challenged by writers in science studies, who identify three major problems in the use of science in democracy: uncertainty, risk and hidden values. They suggest that these problems could be solved through citizen participation.In this essay I perform an analysis of the internal logic of their suggestion. Is it likely that citizen participation enhances the democratic decision making process so as to reduce the problems? The internal analysis shows that it is rational to advocate citizen participation by reasons of legitimacy.

Local politicians are key actors in the democratic system and their ideas concerning democracy plays a central role in local democratic politics. The study's point of departure is the notion that local politicians are dependent of coherence between practice and theory concerning democracy and in the study of their ideas we acquire knowledge about the democratic practice.This study examines the local politicians? view of Swedish democracy and explores the logic of the discourse that makes statements concerning democracy possible. Twenty local politicians have been interviewed and from the material a discourse have been established through the use of formulation of problems and cause, nodal points and chains of analogy which is compared with democratic ideals.The study comes to the conclusion that a hegemonic discourse exists, in which central nodal points are representative and listening. The idea of the representative system is hegemonic and is based in the liberal democratic ideal although the view of the citizens rather can be traced to the radical, communitarian and deliberative ideal.

Föreliggande uppsats utgår från ett potentiellt problem för Försvarsmakten att i det nyligen införda tvåbefälssystemet omhänderta den högskolemässigt utbildade officeren som sannolikt generellt innehar en högre utbildningsnivå och mer uttalad karriärambition än de äldre yrkesofficerarna från det tidigare enbefälssystemet NBO.Uppsatsens syfte är att tydliggöra vilka förutsättningar på arbetsplatsen som gäller för tvåbefälsystemets högskolemässigt utbildade officerare vid officersprogrammet ur ett anställningsbarhetsperspektiv. Anställningsbarhetsbegreppet kommer att utgöra det redskap som jag applicerar på det avgränsade empiriska materialet för att se vilka förutsättningar, som gäller på arbetsplatsen i jämförelse med kraven i examensbeskrivningen för de högskolemässigt utbildade officerarna då de tagit examen sommaren 2010. Är de anställningsbara? Genom en dokumentgranskning tolkas och jämförs de dokument som ligger till grund för officersutbildningen och de strategiska styrdokument som definierar Försvarsmaktens verksamhet.Resultatet visar utifrån ett anställningsbarhetsperspektiv att Försvarsmaktens dokument och officersprogrammets utbildningsplan samt examensbeskrivning i stort sett stämmer väl överens vilket borgar för en hög anställningsbarhet hos officeren..

Denna rapport behandlar utvecklingen av den spelmotor samt spellogik som används i speletSteam Tale utvecklat under projektnamnet Project Steam Age av gruppen StormBound. Speletutvecklades i första hand för mobila enheter, och i rapporten ingår även en kort undersökningav mobila spel i ett historiskt perspektiv. Även spelets genre, JRPG, en förkortning avJapanese Role Playing Game, kommer att förklaras som hastigast med referenser till andraspel inom genren.Spelet programmerades för Android OS version 2.3 och framåt i språket Java. En avsvårigheterna som påträffades, såsom beskrivs i rapporten, var att säkerställa att speletfungerar för den varierande prestanda som mobila enheter utgör, inklusive aspekter såsommed eller utan hårdvaruacceleration av grafik, varierande mängd lagringsutrymme ochprocessorkärnor samt storlek på skärmar. Därtill bör man vid skapandet av en applikation avdenna typ beakta resurshantering, framförallt beträffande grafik och ljud, ett ämne sombehandlas i denna rapport..

Racial discrimination can occur in many ways ? intentional and non intentional ? and in many places ? perhaps most observed in the labor market. The Swedish labor union, LO, is an important party in this market, and discusses the issue frequently in a number of different documents. These documents are being analyzed as discourse in this study, with attention paid to the rhetoric regarding ?immigrants?, i.e.

The purpose of this BA-study is to analyse articles about blood selling and blood donations in the Chinese daily newspaper People?s Daily between 1985 and 1998.With publications of popular scientific material, reports from rallies and portraits of blood donating ?heroes? etc., the People?s Daily, i.e. the Chinese Com­mu­nist Party, actively addresses the underlying cultural reluctance to give blood by different means. People?s Daily and the CCP resolutely aims to transform negative Confucian and other traditional notions of losing blood into represen­tations of courage, honour, duty, etc.

This study examinates technology's traumatic impact on the male subject in The Atrocity Exhibition by J.G. Ballard. In my analysis I show how the protagonist uses a fetischistic strategy in order to make sense of the trauma that technology embeds. Paradoxically it proves to be the agent of his trauma, but also functions as his shield. The machine is thus in a position of the hinge, the point in a structural system that both enables and deconstruct the system.

To reach an Ecological Sustainable Development, Sweden has established environmental quality objectives. Green spaces are attractive for exploitation and in Sweden the access to large jointly green spaces has decreased, which has impact on humans recreation and the biodiversity. The economic aspect has great impact on the planning process which gives indications that the environmental objective may collide with other sector goals within the municipality. The thesis overall aim is to see how the management by objectives for the green spaces implements and how the green spaces is handled in the planning process in a specific case. The thesis builds on a content analysis, strategic interviews and a case study.

Denna uppsats kommer att fokusera kring en teori, stipulationsteorin, för identifikation över möjliga världar. Stipulationsteorin gör att vi kan veta vilka möjligheter vi pratar om. Genom att stipulera möjligheter så kan man identifiera vilka individer och vilka egenskaper dessa individer har i de möjligheter vi pratar om.En teoris ramverk är det som definierar vad teorin refererar till samt vad teorin kan göra. I litteraturen om transvärldslig identifikation så har jag funnit kritik av stipulation i form av problem.1 Dessa problem har betydelse för en värdering av stipulationsteorin. Genom att se teorier som att de bestäms av deras ramverk så kan man göra en uppdelning mellan interna och externa problem.

This thesis analyses the rise and fall of social movements. Social movementsfunctions in the civil society, by contentious collective action they form identities,mobilize their forces and use repertoires of contentions to make new or previouslyunaccepted claims. They function in a limited timeframe, sooner or later they getinstitutionalized, marginalised or succumb into violence. The landless movementin Brazil is one of the most profound social movements in the world; their majorgoal is a land reform. Since the leftwing president Lula da Silva won the Brazilianelection in 2002 the president has been unable to live up to the expectations fromthe landless movement about implementing a land reform.
