Demokratins gränser. Ett liberalt alternativ till påverkanprincipen

What every theory of democracy has in common is a reference to ?a people? who are, in one way or another, collectively self-governing. Given that, surprisingly little attention has been paid to the so called boundary problem of democratic theory, or, in other words, the question of who should be included in the democratic community. Lately, the historically given boundaries have been questioned in favour of a cosmopolitan democracy. Still, little has been said about the boundary problem in general, especially from a theoretical point of view.

Om hur en banks value at risk bäst skattas med expected shortfall

Bakgrund: Om VaR kan estimeras väl med hjälp av ES-metodik, kan man få bukt med VaR-måttets brist på sudadditivitet (vilken innebär dels praktiska problem vid utformning av finansiella organisationers limitstrukturer, dels teoretiska problem i enlighet med Artzner et al (1997, 1999)) samtidigt som man uppfyller det formella kravet på att rapportera sitt VaR på 99 %:snivån. Syfte: Att undersöka hur väl ES ? estimerat på olika konfidensnivåer och med olika metoder ? duger till att skatta en banks 99 %:s-VaR. Metod: Två ES-metoders och sex VaR-metoders förmåga ? både avseende frekvens (Kupiec-test) och oberoende (eget längsta-följd-test) ? att skatta 99 %:s-VaR utvärderas och jämförs.

Risk och osäkerhet i vindkraftsinvesteringar : Hur företagens investeringsbedömning påverkas av deras syn på risk och osäkerhetsfaktorer

Nyckeln till ett framgångsrikt och värdefullt företag är att göra bra investeringar eftersom det är investeringarna som skapar den avkastning som dess ägare får som ersättning (Froot, et al., 1994). Om företaget strävar efter att göra värdemaximerande investeringar måste de därför bedöma vilka investeringar som kan tänkas generera en avkastning som är större än kostnaden för kapitalet som investeras (Brealey, et al., 2014). Detta är den teoretiska grundregeln för all investeringsbedömning (Brealey, et al., 2014). Men eftersom framtiden är fylld av risk och osäkerhet är bedömningen av en investerings ekonomiska värde ingen enkel sak (Sandahl & Sjögren, 2005).I företagens strävan att tämja denna risk och osäkerhet har Mikes (2009;2011) identifierat två olika kulturer, den beräknande kulturen och den visualiserande kulturen. Dessa kulturer präglas av sin syn på vad som är meningsfullt att sannolikhets bedöma och vad som inte är meningsfullt att sannolikhets bedöma (Mikes, 2011).

?Hatar gamlingar färg och att sitta skönt eller vad är problemet?? En kvalitativ studie av ungdomars uppfattning om folkbibliotek.

The aim of this thesis is to study 15 and 16-year-olds? perception of libraries. Despite the fact that the youth is seen as a prioritized group when it comes to library work, the focus is often drawn to the children, and there is a risk that teens and their needs are set aside. My focus is the public library and how the young people in my study use it in their leisure time. The theory of the thesis is a model created by Skot-Hansen, Hvenegaard Rasmussen and Jochumsen and it highlights four possible rooms or functions in a library, concerning inspiration, learning, meetings and creativity.

Det förbryllande sambandet mellan risk och avkastning : En studie av de nordiska finansiella marknaderna

Purpose: The purpose of the study is to in a comparative and causal way explore whether there is a relationship between risk and return and also how it is perceived on the Nordic financial markets.Theory: The theoretical frame of reference applied in the thesis is considered relevant inthe perspective of the study?s purpose and research questions. We have among other theories used The Capital Asset Pricing Model, The Efficient Market Hypothesis and various Behavioural finance theories.Method: The study has its starting point in a quantitative approach with a quantitative data analysis supported by secondary data extracted from Thomson Reuters.Empirics: The empirics contains regression analyses made from calculated secondary data of 240 randomly chosen companies from Nasdaq OMX Stockholm, NasdaqOMX Copenhagen, Nasdaq OMX Helsinki and Oslo Bors.Conclusion: The study conclusions show that there are both a negative and positive relationship between volatility and actual return on the investigated markets. Considering this prior statement we can conclude that the Capital Asset Pricing Model can?t correctly describe the actual relationship between the parameters investigated on the current sample.

Bang! Let's smash the patriarchy Hur svenska serietecknare konstruerar och förhandlar feministiska diskurser

Bokbloggen i de litterära kretsloppen : En litteratursociologisk analys

This thesis explores the position of book blogs in the literary system through Robert Escarpit's socio-literary model of the book market. Simultaneously the thesis serves as a test for Escarpit's theory: by actively applying his theory and model to a very new and contemporary actor on the book market I hoped to reach or confirm new insights into the usefulness and validity of Escarpit's work for contemporary socio-literary studies.Three book blogs were selected for the analysis and interviews were carried out with the authors. The interview questions were formulated specifically for the purpose of extracting the kind of information necessary for an analysis using Escarpit?s theory. As a complement to the interviews, statistics on the type of books reviewed on the blogs were also compiled.

Höjning av vattennivån i Mälaren : Ett hot mot Stockholms centrala delar vid en framtida klimatförändring?

In today?s World is climate change an important and hot topic. Climate scenarios for Sweden show a warmer climate, especially during the autumn, winter and spring. The same climate scenarios also show that the precipitation will increase during this part of the year, however, during the summer the opposite is expected to occur. The purpose of this essay is to examine how future climate change will affect Stockholm especially the expected increase in precipitation, which may lead to a rising level of the Lake Mälaren. During 2000/2001 was Stockholm hit by a flood. This flood nearly resulted in major consequences and showed that there were significant risks for the city of Stockholm and increasing precipitation will result in even more water in the drainage systems of Lake Mälaren. The results presented here show that it is important to increase the drainage capacity of Lake Mälaren in order to reduce the risks of flooding in the central parts of Stockholm.

Vad förklarar variationer i frivillig information?

There is an increased pressure for firms to provide the financial market with additional information. Such disclosure is attached with different kinds of costs. In spite of these costs, and in spite of increased mandatory disclosures, firms choose to voluntary disclosure financial information to analysts and others. This indicates that firms also benefit from providing additional information. The subjects of this study is 431 annual reports from firms listed at the Stockholm Stock Exchange for 2002 and 2005 and the objective is to survey factors that can explain variations in firms? voluntary disclosure.

Motivation och Bostadsköp : Self Determination Theory ur ett konsumentperspektiv

Studiens syfte: Vårt syfte är att med hjälp av en enkätundersökning och etablerade motivationsteorier ta reda på vad som motiverar konsumenter inför ett bostadsköp.Metod: Vi har använt oss av en kvantitativ metod och informationen har samlats in med hjälp av en elektronisk enkätundersökning för att sedan kopplas till Self Determination Theory (SDT).Resultat & slutsats: Resultatet analyserades med hjälp av statistikprogrammet SPSS. Faktoranalysen resulterade i 13 faktorer, vilket slutligen gav en bild av 6 olika typer av konsumenter som alla motiveras på olika sätt.Förslag till fortsatt forskning: SDT skulle kunna användas på fler konsumentområden såsom upplevelser, resor eller för att ta reda på varför vi köper olika typer av varor.Uppsatsens bidrag: Vårt examensarbete har bidragit med att identifiera de motiv som driver oss till bostadsköp. Studien har visat att SDT kan vara ett lämpligt verktyg för framtidens fastighetsmäklare och att resultatet kan vara användbart i fastighetsmäklarrollen. .

Hellre överkvalificerad än undersysselsatt - om övergångsfrekvensen till högre utbildning i Sverige under 80 år

This essay aims to explain the fluctuations in the Swedish transition rate to higher education between 1923 and 2002. With theories of human capital, and screening, as points of departure, seven variables are selected and their correlation with the transition rate investigated by use of graphs and tables. The variables are unemployment, youth unemployment, the supply of academics, cohort size, number of high school graduates from programs preparing for ensuing studies, relative wage trends for worker categories with differing levels of education, and structural phase. Results show that no single variable nor the theories of human capital or screening can explain the fluctuations in transition rate in full. Instead I propose a theoretic model which amalgamates the above and places risk aversion as the driving force behind the individual?s educational decision.
