I denna uppsats diskuteras sambandet mellan risk, marknadseffektivitet och volatilitet. En studie görs för att se om volatiliteten (kursrörligheten) har ökat i enskilda aktier under tidsperioden 1988-1999. Vidare behandlas vilka faktorer som kan ge upphov till volatilitetsförändringar, vilka konsekvenser en förändrad volatilitet får för olika typer av investerare samt om utvecklingen är förenlig med EMH (den effektiva marknadshypotesen).Studier av volatilitet är intressanta p g a den risk som uppstår för olika marknadsaktörer vid en ökad volatilitet. Uppstår felvärderingar på aktiemarknaden finns även risk för att kapital fördelas på ett sätt som inte är optimalt. I stora drag kan man definiera begreppet volatilitet som ett mått på hur stor osäkerheten är inför den framtida kursutvecklingen för en aktie.

Traditionellt sett har olika kapitalförvaltares prestationer utvärderats enbart genom att man har observerat den avkastning som respektive förvaltare har lyckats erhålla. Sedan ett antal år tillbaka har dock den erhållna avkastningen i allt högre grad ställts i relation till den risk som de aktuella placeringarna är kopplade till. Ett sätt på vilket man kan bestämma den risk som en portfölj har är att uttrycka och mäta risken som Value-at-Risk (VaR), vilket kan definieras som ett mått på den med viss sannolikhet förväntade förlusten från ogynnsamma marknadsrörelser över en definierad tidsperiod. Det finns idag både enklare och mer avancerade metoder för att uppskatta VaR. Tidigare forskning har till stor del koncentrerats till att undersöka hur olika typer av VaR-metoder lyckas uppskatta risken för olika portföljer i förhållande till varandra.

In this paper the authors are trying to understand what separates men from women when they save and invest their money. But also what factors that influence them in their decisions. To investigate how men and women actually act when investing their money the authors construct a survey. The authors also turn to the Swedish banks for information on how they think there customers are behaving. The authors find that men are more risk- taking than women and therefore invest more in products with higher risk, for example shares.

AbstractThis thesis analyzes the Russian Foreign Policy Doctrine from a broad theoretical perspective, with the aim of describing and explaining the doctrine using a number of theoretical approaches. Russia's foreign policy has undergone substantial changes since Vladimir Putin became president in the year 2000, involving a radical shift in foreign policy objectives and thereby moving away from the more confrontational and distrusting policies which characterized the Boris Jeltsin regime. Putins doctrine, based on pragmatism and seeking partnership and collaboration with the West, can be described as a near revolutionary re-orientation of Russia's foreign policy guidelines, meaning a transformation of the country's self image which implies a rejection of great power status and a search for a new role in the international community.Our thesis has examined explanatory variables such as the domestic political situation in Russia, the contemporary international system and President Vladimir Putins system of beliefs in order to describe and explain the doctrine. Our results show that the doctrine is largely a product of Putins personality, values and beliefs, but also to a large extent a consequence of necessities, namely the poor Russian economy and the fact that the country no longer can withstand an all out conflict with the West involving an excessive arms race.Keywords: Vladimir Putin, pragmatism, realism, domestic politics, radical change..

Background: There has been an increase in savings and investment in recent years along with an increased interest in responsible investments. Ethical mutual funds has developed and gained increasingly popularity.Aim: The aim of the study is to examine if ethical mutual funds are an equivalent alternative to traditional mutual funds in terms of return, risk and risk-adjusted return on the Swedish stock market.Theory: Beta, Jensen's Alpha, Sharpe ratio, Treynor ratio, and Modern Portfolio Theory.Method: Quantitative survey method, a statistical study.Conclusion:The study concludes that there is no significant difference between ethical and conventional mutual funds in terms of return, risk and risk-adjusted return. The small differences that exist between the two fund groups are in favor of the ethical fund group, indicating that funds is a comparable investment option compared to traditional mutual funds..

Foreign aid is a very debated and controversial topic. The most recent studies have focused more on GDP growth and foreign aid correlation, however not much of the debate has focused on what kind of foreign aid should be given. The most common foreign aid is budget support, often a bilateral funds transfer between two countries. This kind of foreign aid can be both conditional and unconditional from the donors? perspective.

Patienter som är malnutrierade eller risk för sådan kan vara svåra att identifiera inom sjukvården, vilket i det postoperativa förloppet kan leda till komplikationer. Syftet med denna studie var att belysa vilken påverkan malnutrition kan ha på det postoperativa förloppet efter kirurgiskt ingrepp samt vilket tillvägagångssätt som används för att identifiera patienter med risk för malnutrition. Metoden var en litteraturstudie som granskade 10 vetenskapliga artiklar. Artiklarna hittades i PubMed, MedLine och Science Direkt. Resultatet visar att screeningmetoder som kan skilja på den underliggande sjukdomen och malnutrition är mer tillförlitliga. Behandlingen blir mer effektiv eftersom orsaken till malnutritionen identifieras och kan åtgärdas. Risken för komplikationer ökar ju mer malnutrierade patienterna är.

Syftet med denna studie är att undersöka varför triadiska köpprocesser avbryts och vilken som är den vanligaste anledningen till att detta sker. Vi vill få svar på om brist på tillit och upplevd risk, låg användarvänlighet eller bättre alternativ är anledningar till att triadiska köpprocesser avbryts. Vi undersöker även vilken av dessa tre anledningar som är den vanligast förekommande orsaken till att triadiska köpprocesser avbryts. Den empiriska datainsamlingen görs på e-handelsföretaget HinnerDu.se. Det teoretiska ramverket används som grund för den kvalitativa undersökningen som består av 30 intervjuer med personer som enligt empiriföretaget avbrutit köpprocessen på hemsidan.

This essay is about the hostility towards strangers and foreigners within a Swedish historic context, not only towards foreigners coming from another country, but also directed to people within the Swedish society among the ethnic Swedes themselves. From their accounts of the concept I will discuss why and how this hostility towards strangers has developed and been expressed when they were younger, but also how they perceive the phenomena today as it express itself..

Approximately 400 people in Sweden die each year by lung cancer caused by radon gas. Authorities have in recent years invested big resources and organized campaigns to encourage people to take action against high occurrence of radon in residences. With low frequency of applications for radon allowances as the main measure, a lot interprets on a very low commitment. The purpose of this thesis is to investigate the reasons for the low commitment among people. The study is based on a questionnaire survey sent to 444 house owners in Uppsala.

During the last decade a number of studies have been published that investigate how the most fundamental aspect of political organization, the regime type, affects population health. The results unanimously show that citizens of democracies live longer and healthier lives than citizens of non-democracies. Many explanations for this have been suggested, among these are that democracies redistribute more and invest more in salutogenic resources, and that the tendency of dictatorships to control the media negatively affects the ability to spread information crucial to public health. When these mechanisms are controlled for, however, it turns out that democracy has a large residual correlation with for example life expectancy, which suggests that other mechanisms are also involved.In this paper two new mechanisms regarding the possible psychosocially mediated health effects of the regime type are investigated, namely political repression, and the possible negative effects this might have on the levels of chronic stress, and autonomy, which connects to a large previous literature in social epidemiology. In the paper an ecological cross-country design is used and country-level data, provided mainly by the World Bank and Freedom House, is analyzed with a simple multiple OLS-regression model.

Libraries all over the world struggle against the threat of decreased funding and a lack of governmental interest. In countries with an under-developed library sector the interest from the government is often minimal or non-existent. Since the 80´s Sida, the Swedish International Development Cooperation Agency has contributed to the library development in Central America through the Royal Library of Sweden. Nicaragua was the first country to be counterpart in the project. For a period of eight weeks I have completed a field study in Nicaragua and visited the National Library Rubén Darío and public libraries in the country.

This thesis is a case study with a qualitative approach. The company examined is The Astonishing Tribe (TAT) making user interfaces for mobile phones. The company has had a growth of 1453% from 2002 until 2006. We have examined what are the key factors for keeping innovation while growing. The most significant factor not supporting innovation within the case company is the will to take calculated risks.

This master thesis summarizes contemporary theories on secularization processes in the Western world, and compares these with the example of Sweden, which by many scholars is considered to be the most secularized country in the Western world.I do this by dividing the most influential theorists in five different groups. In each group I explain how the theorists formulate and motivate their positions. These groups are:1) The secularization paradigm, where secularization always accompanies modernization. (Therorists: Steve Bruce and Peter Berger (in the 1960s)2) The paradigm basically accepted, but revised to depend on existential security, rather than modernisation as such. (Pippa Norris and Ronald Inglehart)3) Religion returned in the public sphere.

Agricultural drainage is widely used to manage the amount of water in the ground in order to improve conditions for cultivation. However the effects of drainage companies on water regimes are considerable leading to runoff changes such as altered stream flows, peak flows and water levels. In a greater extent this could imply an increased risk for floods along affected watercourses. This study analyzes the extension of agricultural drainage within the drainage basin of Trosaån in Sweden by ArcGIS mapping. In a statistical analysis, historical variation in streamflow in relation to mean precipitation and mean temperature are investigated for the study area.
