What is located on the bottom in the water outside of Birka? Remains of a water palisade or jetties and other constructions.Birka a Viking Age town that existed between AD 750 and 975 was located on the northwestern part of the small island of Björkö, in the Mälar archipelago of the Baltic Sea in Sweden. The Town was protected onshore by a hill fort and a town rampart. It is a widely spread assumption that Birka had a water palisade as a part of its defense. There are logs and other remnants on the bottom of the lake dating back to the Viking age.

Certain types of waste, e.g. bottom ash originating from municipal solid waste incineration (MSWI bottom ash) can be used as road construction materials. A potential problem is the possibility of substances leaching out of the road and spreading in the surrounding groundwater.The aim of this master?s thesis is to conclude whether hydrogeological type settings can be employed to, based on local conditions, provide an estimate of the probable spreading of these substances in the surrounding groundwater, and whether certain types of soils can be identified as being less suitable for the localization of a MSWI bottom ash road. A hydrogeological type setting is defined as a mappable unit with similar hydrogeological properties.

The following essay examines the conditions of whether a child perspective is recognised in the second authority of the new Swedish asylum process, the Migration Court of Law and inquire into the viewpoint of these decision makers as to what a child perspective in this context represents.The method used was a qualitative study that contained interviews with eight respondents, divided into four judges and four jurors. The material gained from the respondents was then analysed by using theories regarding a child perspective and theories that deal with interpretation of a text, ethics and court sociology.A few conditions of whether a child perspective is recognised has been revealed and we also found that the child perspective in theory is a wide perspective, that includes many aspects of how a child is recognised. In practice, however, the child perspective can be divided into two separate perspectives where one of them involves an adults view of a child?s perspective, and the other involves the perspective of a child, the child?s own view of its existence and perceived reality..

The freshwater pearl mussel (Margaritifera margaritifera) is threatened throughout its range. There has been a substantial decline of the species and one major reason is habitat degradation. We investigated how the substrate composition of the bottom floor affects the regeneration of the mussel by analyzing data from the Västerbotten County Board?s inventory of the freshwater pearl mussel. The results implied that fine material such as fine sediment and sand might be detrimental to regeneration whereas gravel and boulders and in particular stone seem to be beneficial.

Enligt den traditionella modellen av skattekonkurrens ska kapitalets mobilitetresultera i ineffektivt lågt satta kapitalskattesatser som med tiden kan leda till endestruktiv ?race-to-the bottom?, dvs. att länderna kommer att successivt sänka sinaskatter för att attrahera kapital. Detta kan innebära en välfärdsförlust för alla länder.Verkligheten ser dock annorlunda ut. I takt med att kapitalmarknaden liberaliserades iEuropa har de flesta länderna höjt kapitalskatten, även de som hade en relativt högskatt från början.

As stocks have become a more common way for people to save their money, the range of financial information has had a substantial increase. To understand the assumptions that stock valuation and analysis are built upon, it is important for the reader to have an understanding for the models that are used by banks and institutions when recommendations are published.The cash flow model, which is the most commonly used stock valuation tool, is based on CAPM. This model describes the relationship between an assets return and its risk in relation to an index. The risk parameter is called the beta value and has grown to be the dominating risk factor within financial economics literature.The use of beta values has been widely discussed in the world of academics and some researchers claim that the degree of explanation brought about by the beta is so low that it should be discarded, others are faithful to the beta and believe that it still serves a purpose. As a result of this criticism other ways to calculate the beta have surfaced, models that take other factors of risk into consideration.

Fokus i denna uppsats ligger i att jämföra fyra organisationers hållbarhetsredovisningar och se i vilken utsträckning de uppfyller GRI:s riktlinjer för ekonomisk påverkan. De fyra organisationer som granskas är Sveriges storbanker, Handelsbanken, Nordea, SEB och Swedbank. Eftersom att de agerar inom den finansiella sektorn har en avgränsning gjorts till det ekonomiska ansvaret eftersom det är det mest relevanta och intressanta att titta närmare på. Problemformuleringen i denna uppsats lyder: På vilket sätt, i sina hållbarhetsredovisningar, tillämpar Sveriges fyra storbanker GRI:s riktlinjer för ekonomisk påverkan? Syftet är att se hur bankerna har presenterat sin ekonomiska påverkan enligt GRI:s riktlinjer och jämföra dessa med varandra. För att få fram information om detta har respektive banks hållbarhetsredovisning för år 2010 granskats och tolkats.
