The purpose of this thesis is to analyze whether macroeconomic variables affect the stock market volatility defined as the volatility of S&P 500 index returns. Except for seasonal dummies, seven variables are used to explain the stock market volatility: default spread, volatility of inflation, volatility of Industrial production, implied volatility, slope of the yield curve, volatility of 3-mo
A wave atlas describing the monthly wave climate at 5 locations along the Swedish SE coast was desired. Using the WAM wave model to hindcast the waves between Jan 1st 2004 and Dec 31st 2009 the parameters significant wave height, direction of wave propagation and spectral wave peak period were extracted from the time series and assembled in a wave atlas. The model was forced with point source wind
Minskning av resultatet i svenska bolag genom koncerninterna upplåningar är ett relativt enkelt skatteplaneringsförfarande som syftar till att reducera de totala skattekostnaderna i en internationell koncern. Förfarandet går generellt till så att ett svenskt bolag tar upp ett lån från ett annat bolag inom koncernen etablerat i ett lågskatteland. Räntan som löper på lånet dras som en kostnad i det Reduction of the result in Swedish companies through intercompany bor-rowings is a relatively simple tax planning procedure aimed to reduce the fiscal costs in an international corporate group. The procedure is generally composed of a Swedish company raising a loan from another company within the group established in a low-tax country. The interest on the loan is deductible in the Swedish company,
User-Centered Design is not a complex notion, but it is a very challenging process for organizations to implement. Therefore this thesis is focusing on how User-Centered Design improves the usability of information system in practice, how user involved and in what way usability is ensured in a system up grading project in a Scandinavian energy company. In order to make the argument, we have collec
The study of mental well-being has a long history, but it isn´t until the last decade or so that it has regain interest in psychology with the establishment of positive psychology as a new research discipline. The present research builds on theories of mental well-being as a continuum, in which complete mental health is labeled flourishing and incomplete mental well-being is categorized languishin
Gestures are used by people in all cultures to express themselves. This is done through both conventional gestures, sometimes called emblems, and non-conventional gestures whose meaning is more dependent on the situation in which they are made. The purpose of this study is to examine how Swedish children between the ages 18 and 30 months use nodding and head shakes, both of which are conventionali
An introduction of real-time prices of electricity, i.e. prices that correspond to the hourly spot market price, for residential consumers in Sweden has recently been suggested. Support for real-time pricing comes from governmental agencies as well as commercial interests, however without a good understanding of how a shift to real-time prices would affect prices and volumes in the market, and wha
Populärvetenskaplig sammanfattning: Vulkanism associeras av de flesta med magmatisk aktivitet och väldiga lavaflöden. Trots detta finns det över hela världen tusentals exempel på ”vulkaner” som oftast inte alls har med magmatism att göra – slamvulkaner. Slamvulkaner drivs genom helt andra och mycket ytligare processer. Slamvulkaner kan bildas i olika miljöer på en rad olika sätt vilket medför attMud volcanoes are pathways through and within which buried argillaceous loose sediments and lithified rocks are altered and transported back to the Earth’s surface. The types of mechanisms of formation, maintenance and triggering of this natural, sedimentary recycling-process vary largely whereby external as well as internal properties of mud volcanoes differ greatly. Sizes range from millimetres
During the Middle Ages the poor had a special place in society and were viewed upon as a means for others to reach salvation. This picture changed during the Reformation and poverty was seen both with aversion and suspicion and the Lutheran work ethic was predominant. At this time poverty was not considered to be a social phenomenon, but rather a moral defect, and most poor people were regarded to
Meteoriter är indelade i tre huvudsakliga klasser, järn, sten-järn och stenmeteoriter. Stenmeteoriterna är vidare indelade i primitiva akondriter och kondriter. Kondriterna är vidare indelade i fyra grupper, enstatitkondriter, vanliga kondriter, kolrika kondriter och rumurutikondriter. Dessa grupper är i sin tur indelade i undergrupper, enstatitkondriterna är indelade i EH (hög FeO-halt) och EL (lMeteorites are divided into three basic groups, iron, stony-iron and stony meteorites. The stony meteorites are further divided into primitive achondrites and chondrites. The chondrite class is divided into different groups, enstatite chondrites, ordinary chondrites, carbonaceous chondrites and rumuruti chondrites. The enstatite chondrites are divided into EH and EL, which stands for enstatite hig
Populärvetenskaplig sammanfattning: Då man för ner en elektrisk ström i marken kommer vissa material i marken laddas upp p.g.a. att positiva och negativa joner samlar ihop sig på ytor och i trånga porkanaler. Detta kallas för polarisering och kan användas för att bestämma t.ex. vad för typ av geologiska material som finns under markytan eller vart föroreningar i marken tar vägen. Fenomenet som uppIt has been shown that surveys of Induced polarization (IP) often contain data of low quality, because it is highly sensitive against different noise sources. When measuring induced polarization, where the method uses multicore cables and continuous electrode sounding (CVES, Continuous Vertical Electrical Sounding), noise phenomena such as capacitive coupling effects have to be considered. It is p
Fjorton, något överlappande, en meter långa borrkärnor har tagits från mossen Taniente Palet bog på ön Isla de los Estados, belägen i Tierra del Fuego i Argentina. De fjorton borrkärnorna bildar tillsammans en hel sekvens på ungefär 10.90 meter. Borrkärnorna har beskrivits och korrelerats, både visuellt och med hjälp av magnetisk susceptibilitet och glödförlust. Tolv prover har också tagits för ålFourteen somewhat overlapping 1-m cores, forming a total sequence of about 10.90 metres, were retrieved from Taniente Palet bog on Isla de los Estados, Argentina. The cores were described and correlated both visually and by measuring magnetic susceptibility and loss on ignition. Twelve samples were also taken for radiocarbon dating. The results were then interpreted and compared with those from ot
Vid tunnelbygget genom Hallandsås i nordvästra Skåne har man stött på tre större vittringszoner och har periodvis haft problem med stort inflöde av vatten till tunnlarna. Detta vatten kommer från de ovan– och omkringliggande akvifärerna och dräneringen registreras som sjunkande grundvattennivåer i kontrollbrunnar på åsen. För att försöka skapa en bild av sprickakvifärernas utbredning i området ovaDuring the tunnel boring project through Hallandsås in the northwestern part of Skåne, large-scale weathering zones have been encountered and there have periodically been problems with great amounts of water leaking into the tunnels. This water comes from the above and surrounding aquifers and the drainage is registered as sinking groundwater levels in control wells on the ridge. In an attempt to
Today communication through an interpreter at authorities is a common phenomenon in Sweden because there are people living in the country who do not understand or speak the Swedish language. This paper focuses on the use of interpreters in the judiciary and how the interpreter misses in this occupation may threaten the rule of law. The purpose of this paper is to investigate if the current interpr
