Vattenapeteorin: Paradigmskifte eller pseudovetenskap?
The Aquatic Ape theory was first formulated by Alister Hardy in year 1960. All from the beginning the theory has been criticized, ridiculed, ignored and a source to strong feelings in the anthropological community. The purpose of this essay is to investigate why the Aquatic Ape theory is so controversial and why it is understood so differently by scientists. After interviews with Swedish scientists and the general community, and after reading of anthropological books, I have tried to show that the aquatic ape-coldness depends on it challenging nature against the anthropological paradigm, which describes human beings as strong, hunting creatures who can live in any environment. The Aquatic Ape theory - on the other hand - picks out one of all these environments and says: "here has our evolution occurred: we have been aquatic apes".
Indirekta och direkta inflationsprognoser: En studie baserad på svensk kvartalsvis inflationsdata
Uppsatsen undersöker vilken av den indirekta och den direkta metoden som bör användas vid prognostisering av den svenska inflationen baserat på kvartalsdata för perioden 1993:1-2005:4. Ytterligare en aspekt med uppsatsen är att ge ökad förståelse för hur inflationen i Sverige i allmänhet ska prognoostiseras. Prognoserna skapas med de respektive metoderna och jämförs därefter med faktisk inflation för att utvärdera vilken metod som ger minst prognosfel. De slutsatser som dras från undersökningen är att det inte är en av metod som strikt föredras vid prognostisering av den svenska inflationen. De metod som är bäst av den indirekta och den direkta beror på prognoshorisonten.
Har fondförvaltare timing och selektivitet? -En empirisk studie av fondförvaltares egenskaper
Abstract Syftet med uppsatsen är att empirisk testa om fondförvaltare uppvisar timing och selektivitetsförmåga, det vill säga om de har förmåga att förutse aktiemarknadens rörelse och att hitta vinnaraktier. Våra undersökningsdata sträcker sig under en tvåårsperiod och omfattar 40 globalfonders dagsavkastningar. Vi har utifrån två olika modeller undersökt om det går att påvisa förmågorna timing och selektivitet. Undersökningen genomförs via ett antal OLS?regressioner där timing och selektivitet kan påvisas.
Den svenska arbetslöshetsförsäkringens effekter på långtidsarbetslösheten
This is an examination of the Swedish unemployment insurance system and the effects it has on the Swedish long-term unemployment. A search model is explained to give an understanding to the incentives of the unemployed. Different mechanisms that create unemployment and that could create long-term unemployment are investigated, but primarily the unemployment insurance is in focus.The Swedish unemployment insurance has undergone several changes the last fifteen years that have improved its efficiency. The introduction of a finite duration of unemployment insurance entitlement was an important step and so was the decrease in the replacement ratio. Even so, I assess that there is still room for improvements of the incentives to search for work among the unemployed.
Patent och företags storlek - finns det en tröskel till inträde?
Several studies have investigated the relationship between different measures of innovative activity, such as patent statistics and R&D expenditures and some have looked deeper into the differences between large and small firms regarding number of patents issued per employee or per R&D dollar. In this paper, the objective is to find out if there are any indications of a barrier to entry (due to economical factors, lack of knowledge etc) for small firms to get into the field of patent handling. The approach is to first set up a hypothesis based on some simple assumptions about how firms would make decisions about whether to apply for a patent or not and thereafter use econometric methods in an empirical investigation. The data used for this study are figures on number of employees, number of patents granted and R&D expenditures for the Swedish firms in the pulp and paper industry. The main conclusion is that, based on the analysis of the data from this rather limited group of firms, no such barrier can be seen..
Rysslands piratisering- Vad gick fel och varför?
The transition from a planned economy to a market economy was initiated in Russia in the beginning of the 90s. The three components: privatization, liberalization and stabilization constitute the trinity of the transition theory. This thesis has its focus on the privatization, that also can be referred to as a piratization of Russia. The purpose of the thesis is to explain what went wrong with the privatization, and also why it went wrong. A few men, called oligarchs, got their hands on great wealth which has lead to an abuse of power.
Hur har handeln med omvärlden påverkat det effektiva utbudet av arbetskraft i Sverige? - faktorinnehålls-analys för år 1995 och 2000
Through trading with countries that have a relative aboundant supply of labor, Sweden changes it's effective supply of labor, in a Factor Content perspective. This essay does two Factor Content analyses, one for year 1995 and one for 2000. The first comparison of these analyses shows that Sweden exports about 27 600 labor-years more year 2000 than 1995. However, since Factor Content analysis arguably underestimates the imported labor, some assumptions are made in order to correct for this. This correction has great importance for the final analysis.
Ut ur Östersjön genom vassen : beskrivning av övergödningsproblematiken samt optimering av en reningsmetod genom skörd av vattenväxter
This study is based on AgroSeas business idea from environmental problems to valuable resource, with the objective to optimize a method to purify the already eutrophicated Baltic Sea by harvesting water plants, mainly reed. The nutrients will then be recirculated to arable land through residues from biogas production. The amount of nutrients that can be removed by harvesting the biomass
depends on the amounts of biomass and the nutrient content of it, which in turn is strongly dependent on the nutrient concentration of the surrounding water. Vegetation suggested in the study for an effective nutrient uptake is helophytes: reed, cattails, reed canary grass, reed sweet
grass in shallower water and lemnoideaes: duckweed and nymphaeids in the deeper parts.
Competitive species has high purification ability but requires regular maintenance to avoid channeling and overgrowth. Regarding time and method of harvest, effectiveness may be improved by: harvesting plants above the water level and after flowering, a border is kept, harvesting twice a season, a bigger machine and a regular maintenance.
This literature has illuminated a major environmental problem and it has been suggested
optimizations for a method for cleaning the Baltic Sea through harvesting water plants, but to get a
definite answer for the optimal method for each site tests should be carried out, this because many
factors determine to what is suitable for each, specific environment.

Fo?rutsa?ttningar fo?r elektrifierade lastbilar med eHighway inom svensk gruvindustri : En ja?mfo?relse av olika transportslag mellan Mertainen och Svappavaara
The Swedish government has a goal of achieving a fossil-free vehicle fleet in 2030. Heavy transport constitutes a significant part of Sweden's transportation sector and the vehicles are driven almost exclusively by fossil fuels. Siemens has developed eHighway, a concept for electric road systems enabling electrification of trucks, in order to reduce the environmental impact of heavy transports. This study aims to investigate the potential that eHighway has on transporting iron ore from the mine of Mertainen to a processing plant in Svappavaara. Electrified trucks are compared with conventional trucks, and diesel and electric trains.The evaluation was made with respect to energy consumption, environmental impact, and cost.
Smittar Rysk räntevolatilitet av sig på Baltisk räntevolatilitet?
Syftet med denna uppsats är att undersöka om ryssladsspecifik räntevolatilitet smittar av sig på de baltiska staterna. Efter den asiatiska krisen 1997 är contagion ett av det mest debatterade ämnena inom internationell finansiell ekonomi och definieras som kriser som smittar av mellan regioner. Metod: 1998 utförde Sebastian Edwards en studie baserat på en bivariat GARCH-modell där han undersökte om volatilitet i den korta räntan sprids från Mexico till Argentina och Chile. Jag följer Edwards (1998) metoder för att undersöka om Baltikums räntevolatilitet är påverkad av rysslandsspecifik volatilitetsspridning. Resultat: Med bristande tillgång till långa tidsserier för emerging markets kan jag inte påvisa någon volatilitetsspridning.
Handel med utsläppsrätter - hur företagsstrategier påverkas :
Climate change is one of the most difficult problems that humans have to deal with. Today, the evidence of human effects on the climate change and the rise of temperature on earth are strong. It is extremely important that all countries get together and cooperate in order to be able to solve the problem with climate change. One step in the work on climate changes is the Convention on Climate Change, which was agreed on in 1992. The Convention on Climate Change resulted in the Kyoto Protocol in 1997.
The Kyoto Protocol is an agreement between a number of industrialized countries to limit or reduce the green gas emissions.

Leder integration till priskonvergens - En analys av de europeiska bilmarknaderna
This study attempts to examine the existence and development of price differences in the car sector in Europe. The time period is between 1995, the year of the Swedish entrance in the European Union, and 2003. The study is based on data supplied by the European commission, on a bi-annual basis. Both price differences in general in the EU, and price differences between Sweden and other countries in the EU are examined. The theoretical law of one price is related to the economic integration of the EU and the car sector.
USA:s bomullssubventioner - effekter på världsmarknaden och utvecklingsländer
The aim of this thesis is to discuss and analyse the American cotton subsidies? effect on the world market in general and developing countries in particular. The amount of U.S. subsidies is substantial compared to most other countries, but a great deal of the effect is due to the USA?s significant share of the market.
