In this study, the sea trout (Salmo trutta) spawning migration was studied in the river Själsöån, Gotland, to assess the main external factors determining upstream migration and seasonal changes in fish parameters. Additionally population trends were studied by examination of old data. The most important external factors for upstream migration were the air pressure, air temperature and wind direction. No significant difference was found between when males and females migrated upstream. Larger females in better condition started migration earlier than the smaller females in poorer condition.

The purpose of this thesis is to examine and analyze the characteristics of the management control system private equity firms use to manage their portfolio companies. The thesis takes a share holder value perspective, and it is assumed that the goal of the management control system is to increase the shareholder value in the portfolio company. In a qualitative study two private equity firms and two portfolio companies, one for each private equity firm, were studied in detail. In total, nine in debt interviews were completed. The results from this study suggest that the characteristics of the control system are dependent on the surrounding context; the focus on shareholder value and the specific characteristics of the private equity industry shape the characteristics of the management control system.

Previous work by researchers as Eugene F. Fama and Kenneth R. French, show that average return on stocks are related to a firms characteristics like size and book-to-market ratio. These kinds of patterns in average return is not explained by The Capital Asset Pricing Model (CAPM), and are therefore seen as anomalies. Fama and French have proposed a three-factor model, which captures patterns observed in U.S average returns associated with size and value.

The purpose of this study is to explore how teachers in Sweden and Croatia work with children that have problems like ADHD and dyslexia in school. I have chosen to compare pedagogical methods between Swedish and Croatian teachers which are used in work with children with difficulties when it comes to the education and teachers approach to these children. I have done a qualified study and have interviewed teachers in both Sweden and Croatia and one specialist in pedagogy in Croatia. I compared with these interviews information from earlier studies and literature. Results show that teachers in Sweden are of the opinion that every student who has these difficulties is different and therefore the use a variation of pedagogical strategies is crucial.

The thesis handles the principal-agency problem between shareholders and the Chief Executive Officer. The purpose of the thesis was to examine the link between CEO compensation and corporate performance measured as a change in Market to Book ratio. Data was collected from corporate annual reports between the years 2000 ? 2008 and the study covers 39 Swedish companies from the Stockholm Stock Exchange Large Cap list. To examine whether there is a link between the CEO´s compensation and firm performance, we performed a regression analysis, and no significant relation is found.

Vägar och järnvägar är viktiga transportsystem som har stort påverkan på vårt vardagliga liv. Att fortsätta utvecklingen för att skapa större förståelse för hur dessa konstruktioner påverkas av nedbrytning är viktigt för att inte skapa långlivade konstruktioner som inte uppfyller morgondagens förändrade krav. Hos konstruktioner som består av ballastmaterial beskrivs nedbrytning orsakad av yttre laster främst som förändringar på jordmassans egenskaper. Ett steg i riktningen för att bättre förstå nedbrytning är att beskriva de kornformsförändringar som uppkommer. Ett antal beskrivande storheter för kornform presenteras: soliditetcirkularitet, aspect ratio, roundness och .

The aim of this study is to learn about the nineteenth century poor relief system, how itoperated in the rural parish Kristdala during the period 1881-1890, and not least, who was thesupported person? The poor are defined as the individuals that received public poor relief, but in onechapter this definition of poverty is contrasted with a definition based upon tax exemption:inability to pay taxes. Two villages have been selected for intensive study, namely Kroxhult and Calerum, and Calerum is the smaller one. The connection between age and the poverty ratio is clear, and tobe a lodger was especially disadvantageous with respect to poverty. Further the position ofwidow was the most unfavourable among the female poor people.

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

International expansion has long been associated with a positive trend that many companies, regardless of industry, choosing to realize mainly to expand its market share and hence its profitability. Various theories describe differentiated strategies to promote corporate expansion. Either they shall be financed by internal funds, or balancing equity with debt, or only increase leverage in order to achieve the desired results. This study focuses on the Swedish fashion market and its degree of internationalization. The purpose is to attempt to discern whether there exists a correlation between the degree of internationalization and its financial performance.The study was based on a quantitative approach where secondary data was collected so that we then would be able to perform regression calculations.

In this investigation has an attempt to find out whether so called transplanting shock depends on the moving and transplanting of trees, to other conditions, or if it is due to the imbalance between the root to shoot ratio. Seventy trees of Prunus avium have been part of the investigation and these trees have been divided into four different groups depending on methods of production, untouched on the field, trees still on the field but with root pruning, trees moved and planted into Root-Control-Bag, trees moved and planted into Spring-rings. To be able to answer the question, measurements of the length of the terminal shoots and the lateral shoots and the dimension of the stem growth have been done and also has a visual judgment of the trees vitality been performed. The result shows that it is not only the move of the trees that gives them transplanting shock, but rather the loss of roots which gives an imbalance between the root and crown..

Until recently, the art market has expanded for several consecutive years. The primary art market is characterized by an unclear pricing mechanism and an infinite as well as limited supply. Previous business studies have so far primarily focused either on art as an investment or on the gallery?s activities. This thesis takes an explorative approach and aims to shed a light on the art collector?s behavior on the Swedish market for contemporary art.

The economic prerequisite to many farmers in Sweden after the EU membership and the new agriculture policy has generated large demands on the farm management. Until year 2004 you got a grant based on what you had produced and not on consumer demand. In 2005 a new economic aid (Mid Term Revue) was introduced and the conditions has changed again. Due to this I have chosen to do a cost-benefit analysis on a case, to investigate if the present production is sustainable in the future. My conclusion is that the profitability is acceptable even if the farm has a high debt. But to make the production more profitable the products produced should be refined as much as possible at the farm, to get maximum economic return.

Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. Our understanding of factors involved in the production of MeHg is very important for making a reliable risk assessment. The purposes of this study were to investigate the different factors that control the solubility of Hg and the production of MeHg in a contaminated lake sediment. The lake Ala-Lombolo, Kiruna municipality, is well-known to be contaminated by mercury from different sources. Sediment cores were sampled at three different locations (N, SW and SE) in the lake and divided in three different layers; 0-5, 5-10 and 10-15 cm.

During the recent financial crisis there has been an intense debate regarding small enterprise?s possibilities to borrow money. Statements from interest groups and results from surveys among Swedish non-financial companies indicate that their situation has worsened. Credit worthy enterprises that under normal circumstances would not have any problems getting financing are now facing financial difficulties. In contrast, an economic report from the Bank of Sweden concludes that Sweden does not suffer from a severe credit rationing due to the financial crisis.

In southern Sweden, beech (Fagus silvatica) and spruce (Picea abies) are two species with similar demands on soil properties. With increased global warming and high acid deposition the future may bring larger areas were the two species are overlapping, competing for the same soil. The aim of this study was to compare spruce and beech concerning distribution, cultivation and soil properties. From available data comparisons were made between spruce and beech forests in Sweden. Soil analyses were made on samples from beech forest in southern Sweden, with and without natural regeneration of spruce.
