In many regulated rivers, authorities have stocked hatchery salmon to compensate for loss of wild populations. However, hatchery fish have not always behaved as wild fish do, and stocking them has not always fully compensated for the loss of wild fish. The purpose of this study was to compare swimming behaviour in the river before spawning, the choice of spawning areas and body size between wild and hatchery-reared salmon in the river Klarälven. Salmon behaviour in the river before spawning was analyzed using radio telemetry. The salmon were caught at Forshaga power plant, radio-tagged and returned to Klarälven at Ekshärad, 107 km from the river?s mouth.

The loss of habitat is one of the greatest threats to global biodiversity today. Consequences to a species inhabiting fragmented habitats include: group size changes, altered diets and altered foraging behaviours. In my study I observed Colobus anlgolensis palliatus troops living in the forests of Diani, a highly developed area on the Kenyan coast. I looked for differences in behaviours between three troops inhabiting pristine forest patches and three troops inhabiting highly degraded forest areas. I used focal animal sampling with instantaneous sample points.

One could argue that the most discussed topic in finance is whether or not it is possible to ?beat the market?. Even though many people claim to do this, there is little evidence to support the idea that one can consistently beat the market over a long period of time. There are indeed several examples of investors who have managed to outperform the market consistently for a long time, but the efforts of these individuals or institutions could by many be considered to be pure luck.One of the many strategies that have been evaluated by several researchers and is said to generate a risk adjusted return greater than that of the market, is one based on the P/E-effect. This strategy is based on the financial ratio P/E ? price divided by earnings ? and used by constructing portfolios consisting of stocks with low P/E ratios.

This thesis investigates the socio- and environmental economic effects of a deep repository for spent nuclear fuel in Forsmark in the municipality of Östhammar. I seek to show the general picture but focus on the effects on employment, environment and income. Cost-benefit analysis is used to investigate the differences in utility between a scenario with and a scenario without a deep repository in Forsmark. Most of the possible effects can not be valued and many can not even be quantified with the data available today. Therefore this thesis has a bit of a ?preliminary study character? and seeks to show what we know today and what needs to be further investigated when available data allow it. The costs that could be valued are noise from the traffic during the period of building and emissions of carbon dioxide and nitrogen oxides from the transportation of rock masses during the building period.

This paper presents the results from an osteological method study of the Ringsjöholm fishbone material. Ringsjöholm is located in Scania, southern Sweden and is 14C dated to 5960-5200 B.P. The aim of this paper is to critically analyse methods used on fish bone material in estimations of season. Three different approaches were used to estimate the fishing season at the Ringsjöholm settlement; 1) identified species, 2) size estimations of the pike based on Enghoffs (1994-95) regression formulae of os dentale, and 3) growth rings of the pike vertebrae.The identified species and the size estimations of the pike points to the fishing being active both during spring and summer. Growth rings analysis of the pike vertebrae didn?t give any quantitative results because of fragmentation.

This investigation?s task was to map manufacturing of special qualities at Stora Enso Packaging under a certain period, analyze if rules concerning special qualities is followed, which consequences this results in concerning use of paper, waste and costs and to give suggestions on alternative solutions. The goal was to give sugges-tions that help the company to reach its business ratio that the production de-partment uses within use of paper and productivity in the corrugated cardboard machine.Stora Enso Packaging is a part of the forest group Stora Enso and is one of Swe-den?s leading producers of corrugated cardboard. Stora Enso Packaging acts pri-mary on the Swedish market, where they have a market share of 25 %.To be able to analyze orders with special qualities we did a data collection during two months, where we mapped incoming orders.

This report is the result of a thesis conducted at the consulting firm Bjerking AB andis the final part of the Bachelor Programme in Construction Engineering at Universityof Uppsala. The work aims to investigate the costs and how the choice of ventilationsystem affects building projects during a long-term period. This report covers costssuch as investment, maintenance and energy but also how they affect residents andbuilders. Building regulations for energy consumption are expected to be tougher;therefore a comparison of two different heat recovery ventilation systems(HRV-system) was made. One system is based on a centrally placed unit that coversthe whole buildings ventilation through vertical shafts.

A business is always dependent on its customers. It is therefore important to ensurethat customers are satisfied with the product and the warranty included.The study was conducted in cooperation with the building contacting companySkanska Sweden. The aim is to use interviews to collect and process experiences in order to answer the question: How should the recovery process in the construction industry be performed to ensure a professional handling of warranty? The results have shaped my conclusions and I have turned them into a proposal that companies in the industry can benefit from. The study indicates that the industry is not geared for a five year warranty, which was introduced in 2004 and 2006.

Construction of wetlands in the agricultural landscape may reduce nitrogen and phosphorus transfer to streams, thereby reducing the eutrophication of lakes and seas. The agriculturalstream Lillån, a tributary to stream Sagån, ends up in Lake Mälaren and is transporting large amounts of these plant nutrients. The aim of this study was to estimate how hypothetical wetlands of different size and location may reduce nitrogen and phosphorus load from stream Lillån. Estimated nutrient retention in several small wetlands was compared to retention in a single large wetland based on existing data from the agricultural stream and from a nearby smaller stream. Retention in the stream was suggested to decrease along with the nutrient concentration in the water.

The study aimed to investigate the acute medical chain consisting of SOS operator, ambulance nurse, emergency nurse and emergency physician with regard to the assessment and prioritization of the victim.The design of this journal study is retrospective with descriptive approach. Data were collected from all ambulance missions carried out in Uppsala county 2009-01-01 between the hours 00:00 to 12:00. Sample period was chosen because the prerequisite for high frequency on the ambulance mission was supposed to be good. In order to be able to systematize the compilation of data a protocol were prepared and used. Applicable data were collected from three databases SOS Alarms, ambulance operations, and the University Hospital in Uppsala.

The usage of temporary work agencies services is increasing in the Swedish labour market and it has also caused some problems. There have been cases where employers have been accused to circumvent the preferential right to reinstatement by using temporary agency workers rather than rehire preference eligible employees during labour need.The purpose of this thesis is to describe, analyse and enhance the understanding of the preferential rights to reinstatement and study when hiring of temporary agency workers, during the period when there is preference eligible former employees, is permitted. The method being used in this thesis has been applied with particular attention to the directives, laws, legislative history and doctrine.The preferential rights to reinstatement in 25-27 §§ of the Employment Protection Act is a protection which states that the employer has to hire employees or former dismissed employees during increased labour needs. The purpose of this right is that an employer should not be able to terminate an employee due to redundancy and then later hire new employees. An employee is entitled to the preferential right as he/she meets the criteria of the Employment Protection Act.

Syftet med examensarbetet är att skapa förståelse kring hyresutvecklingen på kontorsmarknaden i Stockholm och att undersöka om det skett en real hyresutveckling under perioden 1980 till 2011. För att göra detta samlades hyresdata in från olika källor för att sedan skapa tre hyresindex för tre områden i Stockholm; CBD (Central Business District), Stockholm city och Stockholm övriga områden. Uppdelningen i tre områden gjordes för att tydliggöra hyresutvecklingen då det är skillnader i hyra mellan områdena. Vidare var en central del i att skapa förståelse att undersöka vilka faktorer som har haft störst påverkan på hyresutvecklingen. Därför jämfördes indexen mot makrofaktorerna BNP tillväxt, inflation, ränta, sysselsättning samt vakansgrad för kontorsfastigheter i Stockholm.Analysen visade att en något positiv real hyresutveckling hade skett inom alla tre områden: CBD under 1980-2011, Stockholm city 1981-2011, och Stockholm övriga områden 1994-2011.

Forecasting stock market returns is an interesting topic since more and more Swedes enter and invest in this market. Theory implies, however, that such exercises should be impossible. The aim of this thesis is to investigate the possibility to forecast future stock returns by looking at macroeconomic variables? history. The study is limited to the Swedish market as it is based on the OMXS30-index which represents the 30 most exchanged stocks on Stockholms¬börsen, the Swedish stock exchange.

This paper aims to examine how the beginning of newly examined teacher?s professional life might look like and also highlight the obstacles that might occur during the induction, the time during which the student becomes the teacher. The paper also discusses what support that is available for newly examined teachers in schools concerning the possibility to have a mentor and a period of introduction.A qualitative method was used for this study and interviews were made with new teachers who shared their experiences from the beginning of their careers. The results from the interviews were also discussed from the points of view of the study?s theories concerning different leadership styles.Two handbooks for new teachers, aiming to support them in their new professional role were compared.
