Syftet med undersökningen är att ta reda på olika svårigheter/styrkor som påverkar elevers prestation gällande matematiska textuppgifter. Vi studerar hur textuppgifter hanteras i undervisningen i två klasser i årskurs tre i ljuset av resultat och rekommendationer från tidigare forskning. Den här undersökningen bygger på observationer, intervjuer oc...
De senaste åren har det författats ett flertal rapporter som visar att svenska elevers kunskaper i matematik sjunker. Som en följd av det har klassrummet varit i blickfånget för att studera kommunikationen mellan pedagoger och elever under matematiklektioner. Syftet med föreliggande studie var att ge ytterligare en pusselbit till den bilden, genom...
The work is focused on the Value at Risk and the Expected Shortfallcalculation. We assume the returns to be based on two pillars - the white noise and the stochastic volatility. We assume that the white noise follows the NIG distribution and the volatility is modeled using the nGARCH, NIG-GARCH, tGARCH and the non-parametric method. We apply the mo...
In this text about the mathematics education in a primary school in the Gambia, I am researching what this mathematics education consists of and what surrounding factors might be affecting it. The pupils of the school in question speak several different languages. This language situation is one of the factors considered in the research. A connectio...
In this thesis the double exponential jump-diffusion model is considered and the Laplace transform is used as a method for pricing both plain vanilla and path-dependent options. The evolution of the underlying stock prices are assumed to follow a double exponential jump-diffusion model. To invert the Laplace transform, the Euler algorithm is used. ...
The purpose of this thesis is to test the risk-measure Value-at-Riskand techniques for calculating it on data from the Financial Crisis of2007–2010. Different “pre-Financial Crisis” approaches to calculatingValue-at-Risk are considered, and tested on data from the period ofthe Financial Crisis. Also combinations of different approaches aretested. E...
In this thesis we use the method of Semantic Mirrors to create a graph of words that are semantically related to a seed word. Spectral graph partitioning methods are then used to partition the graph into subgraphs, and thus dividing the words into different word senses. These methods are applied to a bilingual lexicon of English and Swedish adjecti...
