Då Ryssland tog tillbaka Krim från Ukraina. : En fallstudie av den ryska erövringen av Krimhalvön 2014.
Abstract This thesis is a case study aiming to give explanations to Russia?s annexation of Crimea in March 2014. By using three different theoretical perspectives, realism, regional hegemony and constructivism, the aim is to find different but also complementing explanations to the case. The theories realism and regional hegemony are related and also similar to each other, but still contributes with some different focuses on the case. Both realism and regional hegemony has their main focus on the sovereign state?s security and their power militarily, politically and economically.

Varför tror vi att vissa företagär mer hållbara än andra? : - En studie om hur företags motiv och kommunikation kringhållbarhet är relaterat till konsumenters uppfattning
The number of elderly in Sweden is increasing due to improved living conditions and better medical care. It is important that society adapts to the increase and begins to work preventively to reduce the costs of the increase. An important aspect is the elderly accommodation, the cost of health care in specific accommodation is almost twice as high as those for ordinary housing. Therefore, it is important that we availability adapt dwelling to allow older people to live in ordinary housing for as long as they wish, instead of moving to assisted living before they need it. If we can fulfil the elder?s needs with home care instead, society can save a lot of money.In this report, three different forms of housing has undergone accessibility increases and been inventoried and analysed.
Bentiska evertebraters förekomst i källor på Öland
Abstract The benthic macroinvertebrate fauna of 22 natural springs on Öland was sampled, by using a time-standarized kick/sweep sampling technique, in the end of September and early October. The aim was to determine the number of species and their abundances in the macroinvertebrate communities in springs and how/why these may change between different springs. Likewise there was a purpose to investigate possible differences between springs considering the proportions of the number of species and the abundances of the five functional feeding groups; shredders, collectors, filter-feeders, scrapers and predators. There was also an aim to investigate if the distances betweeen springs had any influence on similarity between the communities of benthic macroinvertebrates of the springs. Analysis from the springs collected material showed several interesting patterns in the number of species and their abundances when compared between springs devided into groups depending on their environmental factors such as depth and pH.
Mobil klientsäkerhet
Denna rapport har i syfte att öka förståelsen om hur man kan öka säkerheten på ett företag som använder sig av mobila klienter. Att arbeta på distans blir allt vanligare, och med de så ställs allt högre krav på tekniken som tillhandahåller möjligheterna för detta. När ny teknik utvecklas kommer ofta säkerheten i andra hand, det man fokuserar på är funktionaliteten. Frågorna man då ställer sig och vilket läsaren kommer skaffa sig mer kunskap om under rapprotens gång är:Hur skall en klient kunna hållas uppdaterad när den är utanför företagets väggar?Hur skall kommunikation kunna ske med företaget på ett enkelt sätt, samtidigt som det också ska vara säkert?Det kommer visa sig att administratören inte är den pusselbiten i säkerheten på ett företag.
Empirisk undersökning av aktieindexobligationer : Till vilken grad tar innehavaren del av underliggande index avkastning?
The purpose of this essay is to evaluate stock index bonds return to risk ratio in order to investigate to which degree an investor in a stock index bond take part of the underlying index return and what the investor must pay for the security of not losing his funds. In order to carry out this evaluation an average return per year and the Sharpe ratio will be calculated and a mean- standard deviation analysis will be made. All investigated stock index bonds are based on a Swedish underlying asset.The results show that the stock index bonds haven?t generated a higher risk adjusted return than its underlying asset. The stock index bonds took part of 57 % of the underlying assets return, and the loss of 10 percentage points per year for the stock index bonds compared to its underlying asset can be seen as the cost for the guarantee a stock index bond gives..
Analys av säkerheten av RFID i inpasseringssystem
Radio Frequency Identification, RFID, is a convenient way to enable contactless identification which does not require any physical nor optical contact. As with any radio-based communication the signal can be intercepted, thus making the technology vulnerable to several kinds of attacks. Interception of communication is not the only threat. Since RFID tags might contain personal information or information that will grant the owner access to secure areas, skimming and spoofing attacks are also major threats against this technology. In this thesis report, the perspective of an adversary is portrayed in an RFID-enabled environment by presenting where RFID is used and how it could be abused.
Folkbibliotekets plats i den sociala webbmiljön: En undersökning med fokus på litteraturförmedling och läsfrämjande
The purpose of this Master?s thesis is to examine the function of public libraries on the social web, focusing on reading promotion and reading stimulation. For an understanding of the larger context regarding public libraries on the social web, we conducted online interviews via email with people in the Swedish library profession, together with a content analysis of various texts on the subject found in library journals and on the Internet. Furthermore to identify the public library's practice on reading promotion and reading stimulation on the social web, we did interviews with librarians at a public library on their use of a blog for this purpose, together with a questionnaire handed out to the library's users on their use and conceptions of the blog.The conceptual framework of this study consists of four key aspects in the theoretical and empirical definition of Library 2.0 presented by Holmberg, Huvila and Widén-Wulff. The results showed that the public library can create a substantial value through its use of the social web, but it?s necessary to have a clear vision of the desired outcome.
Framtagning av förbättringsförslag för SNCR-system
The gas turbines in the Swedish secondary reserve are reaching the end of their technical lifetime, hence alternative solutions need to be considered. One of the solutions thought to have the greatest potential is the use of so called consumptionreduction. By entering contracts with large consumers, agreements are made to reduce consumption in the event of major disturbances in the power system and thus being used as a secondary reserve. This thesis investigates the feasibility of consumption reduction as part of the secondary reserve. This has been achieved by developing a requirement specification for the disturbance reserve and by studying the technical and economic potential for consumption reduction among a range of consumers.The technical potential for consumption reduction that fulfils the requirements for participating in the secondary reserve are on average 750 MW in SE 3 and 98 MW in SE 4.
Near Field Communication : En studie av säkerhetsaspekternas påverkan för mobila betalningar
Near Field Communication (NFC) är en teknik som möjliggjort utvecklingen av vardagliga betalningar med hjälp av mobiltelefonen. I Sverige är betalningar med NFC-tekniken i mobiltelefoner fortfarande i introduktionsfasen. För att denna teknik ska ha möjlighet att fungera som ett komplement till redan befintliga betallösningar, granskas därför möjligheten för NFC-teknik som betallösningsmetod med inriktning på säkerhetsaspekter.Syftet med uppsatsen är att granska säkerhetsaspekter för NFC-teknik som mobil betallösningsmetod samt analysera dessa aspekter för att få djupare kunskap för NFC-teknologins möjligheter. Kunskapen har erhållits genom en litteraturstudie samt kompletterande av en intervju för att få bredd i informationsbehandlingen.Resultatet av studien visar att NFC-teknologin som betallösningsmetod kan påverkas av ett antal säkerhetsaspekter. För att NFC-tekniken skall nå en bredd i marknaden måste flertalet aktörer samarbeta för en standardisering i användandet av tekniken..
Samhällets kropp
The foundation for this thesis lies in whether or not, and how, the body representation in printed commercials, specific products directed to the body (shampoo, body lotion etc.), has changed during the last fifty years. Four years have been chosen because of the changes in society that we believe might have had an impact. The commercials that have been picked out are the ones that best represent the general view of the body. We have found that the changes when it comes to body presentation has followed the social development to a certain degree, but it is difficult to say how much the society has had an affect on the body ideal in advertising. Representations of the male body is something that has escalated since the early 70?s, fifteen years earlier few commercials was made with male models, and the few there were, never showed more than the face.

Folkbiblioteket och postmoderniteten en hermeneutisk studie av debatten om folkbiblioteket i DIK Forum 1998-2002
The main issue of this master is to investigate what influence the phenomenon of postmodernity has on the Swedish public library. Is it possible to talk about the Swedish public library as postmodern, and if so, is it expressed by a postmodern discourse? The concept of postmodernity is defined as an open and inclusive value system where all kind of opinions and preferences take place. According to a postmodern point of view there is no such thing as an objective or general truth. A postmodern ideology does not talk about reality but about realities.
