Nitrogen deposition leads to environmental damage in areas where the nitrogen deposition is high. Southwest Sweden receives an annual nitrogen deposition of up to 20 kg N/ha. Nitrogen that is not assimilated by the vegetation is accumulated in the soil, which may lead to nitrogen saturation and an elevated risk of nitrogen leaching. Nitrogen leaching from forest areas in southern Sweden has proven to be higher than from agricultural areas, which have been thought to be the main contributors to elevated nitrogen levels in rivers and lakes. The amount of nitrogen that leaches depends on the fraction of the total nitrogen in the soil that consists of nitrate, since nitrate is easily transported through the soil.

I denna uppsats behandlas ett nytt sätt att beräkna korrelationen mellan olika tillgångar. Me­toden, tvärsnittskorrelationen, har framarbetats av Bruno Solnik och Jacques Roulet som be­skriver den i artikeln Dispersion as Cross-sectional Correlation. Vårt syfte är att med hjälp av detta nya sätt beräkna korrelationen över en tio års period på den svenska aktiemarknaden och se om vi kan hitta tendenser i korrelationens utveckling. Korrelationens tendens har tolkats genom trendlinjer och determinationskoefficienter. De re­sultat vi får fram tyder på en ökning i korrelationsnivå inom de flesta av våra observerade sektorer på den svenska aktiemarknaden..

The main purpose with this study was to investigate whether the tree growth differs or not in prescribed burnt areas compared to mechanically scarified. Together with the result from the main purpose, answers of whether it's possible or not to combine nature conservation with tree production in prescribed burnt areas was presented. In these areas the regeneration were analyzed to see if there was enough tree plants to comply with the Swedish Forestry Act regulations terms for approved regeneration. A field survey was conducted at 6 objects, three objects for prescribed burning and three for mechanically scarification. All objects were planted within the same year.

PurposeThe purpose of this paper is to assess whether the overreaction found in ?Does the Stock Market Overreact?? by DeBondt and Thaler still persists today, and by equivalence test if a trading strategy based upon these assumptions would generate abnormal returns. MethodThe research has been carried out by studies of the stocks that for a prior period of one year has over or underperformed their benchmark. The stocks used in my study are all part of S&P500 index, and the period of study runs from three to five overlapping years over the last twenty years. ResultsMy tests indicate that the type of overreaction proposed by DeBondt & Thaler still is present, at least considering the stocks that during the formation period were winners..

Aim: The study aims to investigate the distribution of grades between students in a practical subject and in a theoretical subject.The problem:What is the grade distribution in physical education and mathematics, with respect to gender, socioeconomic background, parental education, ethnicity, and physical activity?Method:To answer the aim of the study a quantitative method was chosen. As the collection method used was questionnaires to 620 students in the 9th grade in Stockholm. Of the 620 questionnaires, 597 questionnaires were used for the static analysis. The method of analysis used cross tables and logistic regression analysis.

The study's aim was to examine the professional role of the Special Education Teachers, working with students in socio-emotional difficulties with focus on externalizing behavior. The study is qualitative in nature, based on 10 interviews conducted at four different schools where four Special Education teacher and six teachers were interviewed. The system theoretical perspective was used as a theoretical basis, based on a holistic view of the schools where relationships, interactions and context is of great importance. The Special Education Teacher is a part of the school context and therefore it has been interesting to study how he/she works with socio-emotional difficulties in school activities on organization, group and individual level. The results show that externalizing students becomes a problem in schools today when they influence their surroundings and requires a lot of time regards to needs of both teachers and Special Education Teacher.

Effects of fishery closure on perch was detected as female perch was on average 5 cm longer in closed areas compared to non-closed areas. This could be a result of larger individuals surviving as an effect of reduced fishing. No effect was detected on the reproduction rate of YOY (young of the year) perch.A zooplankton survey revealed less amounts of the most important plankton groups for YOY perch in areas with failed reproduction, though the difference was statistically insignificant.The distribution of YOY perch and YOY/adult stickleback differed completely in this study with no area where the two species are both present. It is sketchy to draw any conclusions from this data but it remains a field for further investigation.The reproduction problem is concentrated to the outer parts of the archipelago which confirms previous studies of the geographic extension..

I denna uppsats har förhållandet mellan statligt kapital, humankapital och ekonomisktillväxt undersökts genom en utvidgning av Lucas modellen. I utvidgningen specificeras hur statligt kapital har en positiv effekt i teknologin för utbildning och en negativ effekt i teknologin för privat produktion. Utvidgningen sker genom att staten fördelar sitt kapital mellan offentlig konsumtion i produktionssektorn och investeringar i utbildningssektorn. Produktionsteknologierna antas sedan bero på kvoten mellan genomsnittligt humankapital och andelen statligt kapital i respektive sektor..

Authors: Lars Johansson & Johan PetterssonTitle: ?There is way to much sports in the athletics? ? A study of Swedish sportsFootball has gone from being a hobby and a popular pastime into a billion-dollar industry, and clubs around Europe are therefore operated more and more like regular companies. Sweden's position in the UEFA rankings is a modest 23 rd place, behind nations such as Austria, Switzerland and Belarus. The economic climate in Sweden is often highlighted as a strong factor. When we started our study we agreed that this could be a major contributing factor to this relatively modest rank, but believed that there were also other factors that played a big role.

There are records of lowering of the water level in a lot of the Swedish lakes from the middleof the 1700th century. The aim was gaining more areable land to meet the needs of more foodto support the expanding population. In areas with top soil which contents of clay or loam asin the southwest of Scania in southern Sweden this was proven to be a successful wayexpanding the total outcome of the harvest.The studied area in the northeast of Scania, though, consists of morain with a lot of mires -much less nutritious conditions. When the water level is lowered the atmosphere gets accessto the peat. The dissolving of the organic matter that has been suppressed by the lack ofoxygene below water level continues.

During Sweden's economic crisis in the early 1990s a governmental committe of prominent economic and political experts were gathered to produce an analysis of and suggestions to the solution of that crisis. The committe produced a report that became widely commented in the media and in parliment. The report anc the reception of it gives us insights in how the boundaries between social science and politics are created an how new fields of expertise is added to a science. This thesis uses a constructivist approach to explore how the techniques of the economic science were made into credible means of knowöedge production outside of the field where it traditionally holds epistemological authority. Working from the assumption that language does things to the objects that it describes I claim that the episode investigated in this thesis was shaped by the committee's ability to define the economic crissi and thus making it into a knowable object.

Today adjustments on the pricing of internal transactions between multinational enterprises can lead to economic double taxation for the involved companies. This circumstance will result in an obstacle for private enterprising on the international market. Rules regarding corresponding adjustments and the mutual agreement procedure, that is used to eliminate economic double taxation, are today not sufficient tools to achieve this purpose. Consequently, changes regarding these rules should be implemented.The main reason for why economic double taxation is not put right is the competent authorities? inability to reach a suitable solution for the dispute.

Den här uppsatsen undersöker om IMF, genom sitt agerande under den finansiella krisen i Indonesien 1997-1998 gav upphov till moral hazard. Problemet analyseras dels kvalitativt genom att titta närmare på de förväntningar som IMF hade på den indonesiska staten och jämföra dessa med den faktiska utgången. Den kvantitativa analysen baserar sig på den monetära betalningsbalansteorin. Genom att observera förändringar i den inhemska kreditexpansionen mäts huruvida den indonesiska penningpolitiken var expansiv eller åtstramande. Såväl den kvalitativa som den kvantitativa analysen visar att IMF bidrog till att moral hazard uppstod..

The aim of this thesis was to use qualitative approaches to show how teachers in primary school reason on their way to meet and communicate with children who have ADHD (Attention-Deficit/Hyperactivity Disorder). Research questions of the study were as follows: How does teachers in primary school reason about their way to communicate with children with ADHD? Do the teachers use some specific methods or means of communication with students who have ADHD? Do the teachers reason about their way how to handle conflicts with students who have ADHD? I collected my empirical material through a qualitative interview method. My theoretical starting points were interaction theory and the socio-cultural perspective. I have used these theories to analyze my material.

This paper investigates how Swedish upper secondary school students relate to the financial support available from the Swedish state of education. It also looks at the attitudes of such students to the new CSN[1]truancy rules as they apply to school politics.Is there a difference in students? attitude to these truancy rules and does that difference depend on the students? socio-economic standard, whether they come from a wealthy background or a marginalised society or whether they are ethnic Swedish? Does this in any way affect the attitudes of the students?This financial support is only paid to those students who do not skip school. If they lose their right to this contribution because of truancy, their parents will also forfeit the right to the financial subsidies to which they may be entitled. Naturally, this may affect students in different ways, depending on what kind of financial situation their family is in.Do some students go to school out of their own financial interest or out of that of their parents? Through focus-group interviews, students have expressed their opinions, told about their experiences and stated their attitudes with regards to these matters.
