Beteende hos lekvandrande lax i Klarälven ? utvärdering av en fiskfälla
During the migration season in 2013 a study on spawning migrating salmon and the effect of water flow on the behavior was conducted of the salmon at the Forshaga hydropower station in the River Klarälven. The River Klarälven with its nine hydropower plants on the Swedish side, constituting migration obstacles for the migrating salmon. Fortum Generation AB has together with the County Administrative Board restored a salmon trap at the lowermost hydropower station in Forshaga, aiming at making it possible for the salmon to swim into the trap, and thereafter be transported by truck past the power plants and then continue their journey to the spawning grounds on their own. Unfortunately, it is believed that the trap does not work as well as it should. In this study, I focused on salmon position in relation to water flow and if the number of salmon that swam into the fish trap differed between salmon with previous experience of the trap (experienced) and salmon without experience (unexperienced).
Hantering och behandling av ferala katter på kliniken
Runtom i världen finns det utarbetade metoder för att begränsa den ökande populationen av förvildade katter. Studier gjorda över så kallade TNR-projekt (Trap, Neuter, Return) har visat goda resultat på den långvariga effekten av minskad förökning, men också på en förbättrad välfärd för individerna. I USA finns det kliniker som arbetar mycket eller enbart med dessa patienter. Dessa blir finansierade genom statliga bidrag, privatpersoners donationer, samt fri-villig arbetskraft. Lämpliga anestesipreparat har utvärderats till just dessa patienter, och rikt-linjer för hantering av icke hanterbara individer finns dokumenterade i flera studier.
I Sverige uppskattas antalet hemlösa katter till cirka 100 000, men problematiken kring dessa individer sköts i stort sett av privatpersoner och katthem.
Relationen mellan failure trap- strategin, depressiva symptom och alkoholproblematik bland studenter
Syftet med denna studie var att undersöka om den teoretiska modellen failure trap- strategin kan förklara alkoholproblematik och depression bland studenter, samt om strategin kan förklara alkoholproblematik ut-över depression. Vi belyser även om strategin bidrar till det dubbelrik-tade sambandet mellan alkoholproblematik och depression. Deltagare var 358 universitetsstudenter vid ett mellanstort svenskt universitet. Deltagarna svarade på en onlinebaserad enkät rörande depressiva symptom, alkoholvanor och användandet av failure trap- strategin. Data analyserades genom korrelations-och regressionsanalyser.
Vattenflödets betydelse för fångster av lekvandrande lax (Salmo salar) och öring (Salmo trutta) : En utvärdering av laxfällan vid vattenkraftverket i Forshaga
Many watersheds have lost stocks of migrating fish species because of the development of hydroelectric plants and other fragmenting barriers. The remaining stocks of migrating Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) in River Klarälven, Sweden are five times smaller compared to one hundred years ago. A fish-trap at the hydroelectric plant in Forshaga has been vital for the continued existence of the stocks. This is the first hydroelectric plant of eight, blocking the way to the spawning grounds. Spawners are collected in the trap for both hatchery and transport by truck upstream and past seven more hydroelectric plants to the spawning grounds, where they are released for possible natural reproduction.

Hemlösa katter i Göteborg med omnejd
Today there are over 100 000 stray cats in Sweden and of these 10 000 are found in Gothenburg. There are several instances that try to reduce the number of stray cats. The problem for stray cats is primarily the suffering they may face in hunger, cold, predators, diseases, parasites, accidents, etc. The cats receive no veterinary care and may die from a simple infection that easily can be cured with antibiotics. Stray cats also can spread diseases to domestic cats, be a sanitary problem and compete with other small predators on prey.
Authorities working with stray cats are the Country Administrative Board and the police authority.
Hur underprissättning påverkar efterföljande prestation
This thesis examines underpricing and the long run performance of IPO firms on the Swedish equity market during 1994-2010. We further investigate whether any correlation exist between underpricing and post-IPO performance during 36 months. We use a sample of 80 IPO firms. To examine the aftermarket performance we compare total return of each firm with a matching industry index. In order to strengthen our analysis, we run a second test, comparing actual return for each firm with expected return, adjusted for firm specific risk.

Empirisk undersökning av aktieindexobligationer : Till vilken grad tar innehavaren del av underliggande index avkastning?
The purpose of this essay is to evaluate stock index bonds return to risk ratio in order to investigate to which degree an investor in a stock index bond take part of the underlying index return and what the investor must pay for the security of not losing his funds. In order to carry out this evaluation an average return per year and the Sharpe ratio will be calculated and a mean- standard deviation analysis will be made. All investigated stock index bonds are based on a Swedish underlying asset.The results show that the stock index bonds haven?t generated a higher risk adjusted return than its underlying asset. The stock index bonds took part of 57 % of the underlying assets return, and the loss of 10 percentage points per year for the stock index bonds compared to its underlying asset can be seen as the cost for the guarantee a stock index bond gives..

The results in general did not show any significant difference in return between the model's portfolio and index.

Prognostisering av räntabilitet på eget kapital - En jämförelsestudie av tre regressionsmodellers prognosförmåga applicerat på svenska data
A multivariate cross-sectional model is used in this thesis to proxy for expected earnings and to estimate return on equity for 214 companies over the period 2009-2013, using Swedish data. The model, which has never been tested on Swedish data before, is first confirmed to function as a forecasting model for expected return. Furthermore, the model is evaluated through a comparison with two univariate models based on the assumption that return on equity follows a mean reversion process. Forecast accuracy is calculated as the difference of estimated returns and actual returns. The results show that the univariate models' forecasts are superior to the multivariate model's..

Piotroski ur ett riskperspektiv : En empirisk studie av 3- samt 4-faktors CAPM
An efficient market implies that the use of fundamental analysis should not result in excess return, and that any return exceeding the market average can be explained by compensation for risk, accord-ing to The Capital Asset Pricing Model (CAPM). The focus of this study is to test whether the suc-cessful investment strategy developed by Piotroski (2000) generates excess return on American data, after risk adjustment by using Fama & French?s (1993) 3-factor and Carhart?s (1997) 4-factor CAPM. Initially we form stock portfolios based on companies characterized by high book-to-market values, additionally, we divide them into different performance classes by ranking them with Piotroski?s (2000) measure of financial performance, F_SCORE.
