Predicting spawning bed erosion and longevity : a case study in tributaries to river Vindelälven, northern Sweden

Timber floating operations in Scandinavia during the 19th and 20th centuries has contributed to severe negative impacts on riverine ecosystems. Increase in water velocity and lack of stream bed heterogeneity as a result of stream channelization lead to increased bed load transport. Since availability and recruitment of new suitable spawning substrate in Scandinavian watercourses is sparse, spawning habitats for salmonids has become a scarce commodity. Lately, increasingly more attention has been given to the recreation and improvement of brown trout (Salmo trutta) spawning habitats in restoration projects. While much of the research on spawning habitat has been focused on evaluation of the influence that the constructed spawning grounds have on fish populations, few studies have been conducted to evaluate the persistence of these constructions over time. I evaluate erosion of constructed spawning beds as an effect of sediment transport attributable to water discharge.

Förskollärares föreställningar om aktivt deltagande i leken : Deltagare eller åskådare?

The purpose of this study is to highlight how preschool teachers reason about their own beliefs about their active participation in the play. The study is a qualitative research method where interviews have been used to talk with four preschool teachers to obtain their perceptions of their participation in the play. I have approached my questions through previous research and theses which turns to play and preschool teachers' involvement. The result of my study shows that preschool teachers see differently on their active participation, but they think that active participation is essential for the development of the play and that by being involved in the play in different ways will create interaction and interactivity. The result also shows that preschool teachers find great joy in participating in the play, and also that many relationships will be established by participation in the play..

Betydelsen av ett moderbolags insyn och kontroll över sitt dotterbolag vid prissättning av koncerninterna lån

Transfer pricing including internal loans have increased in recent years, making it easier for companies to minimize their taxable income. After the Swedish court case Diligentia, there have been discussions regarding the influence of a parent company's transparency and control of the subsidiary with regards to the interest rates on internal loans. In court cases that followed Diligentia, the Swedish Tax Agency argued that a parent company always could be assumed to have sufficient transparency and control of the operations in the subsidiary, and therefore reduce the risk on their debt obligations. This thesis seeks to analyze the effects of the transparency and control a parent company has with regards to interest rates on internal loans. The analysis is conducted by analyzing court cases similar to Diligentia.

Slusseneländet

Stockholm is constantly growing and changing. Despite this, for various reasons, it is difficult to execute large building projects. With starting-point in decision making theories we have tried to investigate these difficulties. More specifically we have chosen to study why it has not been possible to rebuilt Slussen in Stockholm. To help us structure our study we have based our research on another large comparable building project, the Globen City project.

The purpose of this study was that, from a sociological perspective give possible interpretations of the anorexic behavior, and interpret why some anorexics choose to be a part of and identify oneself with the pro-ana movement. The reason has been to conduce more knowledge and understanding of the topics, but also to contribute with a deeper perspective and sociological approach to the former research that is already available.To conduct the study, qualitative research has been used, and the chosen methodology was document analysis/text analysis. The collected empirical data consisted material from two pro-ana forums, four blogs and six twitter accounts, where all the users of those claimed to be supporters of the pro-ana.

Vardagslyx

Our purpose with this research has been to obtain a deeper insight and understanding for the phenomenon and term ?weekday-luxury.?Through our research, we have found a link between value, service, brands and consumer behaviour into a relationship that we termed ?weekday-luxury.? This link of values is particularly interesting to us and we are curious about the underlying motivation to ?weekday-luxury? and the driving forces underlying the phenomenon. We have noticed in society that people need something extra in their daily lives and we attempt to speculate where their perceived value lies through the concept of ?weekday-luxury." Our goal is to determine a deeper understanding and insight into this phenomenon and how it meets our needs through an identifiable pattern. We also analyze the nature of ?weekday-luxury? and its meaning.

Background: In a world that are becoming more and more aware of the climate changes that occur as a consequence of the increasing emissions around the world companies? experience that the opinion blame the internal processors for this.

Kan evidensbaserad design användas i upprustningen av miljonprogrammet?

Between 1965 and 1975 a major housing project was carried out in Sweden to resolve a major housing crisis, the so-called one million housing program (Swedish: miljonprogrammet). To raise the standards and create a more attractive housing in these areas is currently a very relevant topic in Sweden.Evidence-based design is the process of basing decisions of the built environment on credible research and studies to achieve the best possible outcome. This method is primarily used in the healthcare sector to improve quality of care and reduce costs by creating healthy environments.The possibility of refurbish apartment buildings from miljonprogrammet using evidence-based design has been studied by means of an extensive literature review and a closer examination of the residential area, Husby in Stockholm, which has been chosen to represent the miljonprogrammet in its entirety. Furthermore, the evidence-based research has been limited to seven fields; nature, noise, color, wayfinding, safe environment, daylight and thermal comfort which has been assessed to be applicable on housing. In order to obtain a comprehensive overview of the different fields, four different subjects were chosen to investigate further within each field; research and studies, laws and regulations, constructional aspect and Husby.
