Vattenfall hedge its future electricity production in order to decrease fluctuations in theresult. Hedging can in a simplified way be described as selling the future electricity deliveriesin long-term contracts so that the future price of the delivery becomes fixed. The contractsused are electricity forwards traded at the Nordic electricity market Nord Pool. Animbalance between buyers and sellers can lead to a situation where the forward price notequals the expected spot price. The difference between the forward price and the expectedspot price is referred to as the market risk premium.

The aim of this research is to find out what environmental impact a wave power park has on the Swedish west coast by creating a consultation paper (?Samrådsunderlag?) for the Lysekilproject at Uppsala University. To highlight the complexity of the problem a system analytic approach was used and illustrated by a Causal Loop Diagram.The overall assessment of the Lysekilprojects wave power park at the Swedish west coast is that it will have a low impact on the environment. This is due to the relative small size of the wave power park and some technical solutions made with the environmental aspect in mind. Artificial reefs and a sanctuary for marine species are effects created by the wave power park and in the longer term the impact will give access to an untapped source of renewable energy, wave energy.

Syftet är att undersöka om de fyra kriterierna komplementära färdigheter, samarbetsvilliga kulturer, förenliga mål och proportionella nivåer av risk som utarbetats av Brouthers et al (1995) har något empiriskt stöd för olika typer av allianser. Studien är empirisk med ett hypotetiskt-deduktivt tillvägagångssätt med en kvalitativ ansats. Hypoteser framtagna utifrån Brouthers et als teori undersöks för att avgöra vilka faktorer som avgör om en allians blir framgångsrik eller inte. Studien inkluderar även en explorativ förstudie för att konstatera kunskapsläget och formulera en undersökningsplan..

The aim of the thesis is to highlight external factors to explain why the EMU was created. The external factor considered here is the monetary policy of the United States, which often conflicted with European interests. The statistical data in the thesis, as well as previous research, show that even though the EU economically in many ways had become an equal partner of the US during the second half of the 20th century, the union still faced US influence and dependence.The results of the thesis can be explained with neorealist theories on power measured as an actor's distribution of capabilities and balancing of power. An actor that is equipped with the world's leading currency is more independent from others. Other actors, on the other hand, become increasingly dependent on the major currency and the policy of its owner.

Med anledning av den finansiella kris som råder och den påverkan den haft på börs- och räntekurser världen över ansåg vi det intressant och samtidigt relevant att undersöka hur försäkringsbolag påverkas av denna situation. Vi valde försäkringsbolag då de hanterar både sina egna och sina kunders risker samt förvaltar stora portföljer. Den nuvarande ekonomiska situationen var bakgrunden till att studien genomfördes. Uppsatsen syftade till att undersöka om, och i så fall hur, försäkringsbolag anpassar och förändrar sin riskhanteringsprocess och organisation under den finansiella kris som råder. En kvalitativ metod tillämpades, där intervjuer med tre inom Sverige väletablerade försäkringsbolag genomfördes.

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.

In what French philosopher Gilles Deleuze labelled Control Societies, mechanisms reminiscent of censorship ? that is, restriction of information that administrators of power wish to regulate the spreading of ? are present in the concept of copyright. This kind of censorship has the advantage of not being scrutinized by public eyes in the way that the work of institutionalized censorship agencies such as the Swedish Statens Biografbyrå was. It is not unlikely that expanded possibilities for punishing anyone who spreads copyrighted material will result in larger and larger areas that may not be accessed, as the avoiding of conflict and repressive actions will emphasize the behaviour to take detours around information that is deemed taboo and therefore suspicious and dangerous. The ACTA trade agreement is one proposed tool for such extended possibilities for punishment.This essay does not however claim that copyright and censorship are the same ? but rather that the institutional execution of power that was previously a matter of state censorship has a lot of similarities with current and prognosticated application of copyright laws by corporations.

Det här examensarbetet förklarar i olika stor utsträckning några av de vanligaste riskmåtten för marknadsrisker. Störst fokus får Value at Risk och de tre vanligaste metoderna att beräkna detta: Historisk simulation, Varians-Kovariansmetoden och Monte Carlo-simulation. Utvalda riskmått och funktioner har dessutom undersökts och förklarats för tre olika mjukvarupaket designade för att beräkna risk. Skillnader i programmen har lyfts fram, dissikerats och diskuterats..

Syfte: Syftet är att undersöka bankernas tillvägagångssätt när de lämnar krediter till en kund, vilka skillnader och likheter finns mellan de olika bankerna och på vilket sätt använder de sig av riskhantering vid kreditbedömning av hushåll?Metod: För insamling av det empiriska materialet har vi använt en         kvalitativ metod, i form av intervjuer med bankchefer. Det empiriska materialet analyserade vi främst utifrån teoretiskt material kring risker och riskmanagement, konkurrens och relationer.Slutsats: Riskbedömningen hos de olika bankerna görs i stora drag likartat, men det finns skillnader i bankernas hantering när det kommer till handläggarens frihet och hur de personliga relationerna spelar in. Vi kan se att riskhantering sker till stor del reaktivt, bankerna är passiva i förändring av riskhantering och behåller rutinerna så länge som möjligt. Undersökningen visar även att bolånen inte längre är den starka konkurrensfaktorn den tidigare varit för bankerna..

The aim of this thesis is to examine the existence and prevalence of earnings management in Swedish companies. Theoretical frameworks often suggest that there are strong incentives to practice earnings management. The research area of earnings management has, to date, mainly focused on detecting earnings management. However, to our knowledge, no such studies have been conducted on Swedish companies. This thesis provides evidence of the existence and prevalence of earnings management in Swedish companies.

Political realism is a general theory within political science focusing on the principle interest defined as power. The theory?s mutual standpoint is that states are inspired by power politics meaning that military and economic power or security stands in the centre while moral and ethics are placed in the periphery. This essay?s purpose is to analyze realism which helps to understand the development and change of the perspective.

In January 2007 the Öresund committy changed its statutes to become a more politically oriented lobby organization. This change can be interpreted as one part of a continuously evolving process where the Öresund region is emancipating itself from the national states in a multi-level European environment. By focusing on this latest development the thesis puts forward the importance of political institutions, as well as politicians and civil servants as actors in them, as crucial factors in the process where the region is gaining political power. The thesis shows how the political cross-border cooperation in the Öresund region is being institutionalized which affects its power relations to other levels in the multi-level system, predominantly the national states. In other words, there is a connection between power and institutionalization.The Öresund committee has by gaining better access to policymaking agendas on the national levels proven that the organizational change has already started to bear fruit.

The purpose of this study is to examine how adolescents can participate and have influence in the society, by making obstacles and opportunities that are considered central for their possibilities to power visible. National and international research indicates that adolescents opportunities to participation and influence are limited by the structures of society. A qualitative method was chosen, in which group interviews were made with 14 youths in development areas in Örebro. Theories are presented which constitute tools for analysis of the obtained results and has been chosen based on power- and participation perspective. An analytical model has been used to illuminate what kind of participation adolescents have in different parts of the society, where the concepts from the theoretical perspectives, power and participation are inserted.

The purpose of this study is to investigate how power is distributed in the mathematics classroom and how students achieve agency when ICT (Information and communication technology) is used as a teaching tool. Three learning situations, structured by mathematics, are analysed: in the first situation mathematics is taught in a traditional way, in the second mathematics is taught in interdisciplinary projects, and in the third mathematics is taught using ICT as a pedagogical tool. The theoretical concepts of power and agency are used as analytical tools within a socio-political framework. The concept of power is used to assess the students? ability to influence their learning and degree of inclusion in the three learning situations.
