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.

The purpose of this study was to develop two types of prediction models for Scots Pine and Norway Spruce. The first type for calculation of the stump diameter under bark the year the tree reached breast height (Dstubh130). The second type for calculation of the annual difference, e.g. the number of growth years between stump height (0.2 m) and breast height (1.3 meters above ground level). The primary thought with these prediction models is to obtain the breast height age in the trees on basis of the number of annual rings at stump.

Approximately 4000-5000 hectares, of SCA´s forest land area in Västerbotten, are in need of pre-commercial thinning (PCT) every year. Within the management district, the areas annually treated with PCT must increase, in order to decrease the area with an urgent need for PCT. This can be done by employing more forest workers or entrepreneurs, by mechanized PCT or by an extended season for PCT. Positive experiences from a private forest owner, who started to carry out PCT when the first snow came and then continued for several months, gave an idea to investigate the possibilities to prolong the season of PCT. The purpose of this experiment was to compare PCT carried out when there was snow on the ground with PCT performed when there was no snow on the ground.

The aim is to develop a new decision-making model for credit-loans. The model will be specific for credit applicants of the OKQ8 bank, becauseit is based on data of earlier applicants of credit from the client (the bank). The final model is, in effect, functional enough to use informationabout a new applicant as input, and predict the outcome to either the good risk group or the bad risk group based on the applicant?s properties.The prediction may then lay the foundation for the decision to grant or deny credit loan.Because of the skewed distribution in the response variable, different sampling techniques are evaluated. These include oversampling with SMOTE, random undersampling and pure oversampling in the form of scalar weighting of the minority class.

År 2007 gick 5 791 svenska företag i konkurs. Företagskonkurser kan få svåra ekonomiska konsekvenser för företagens intressentkrets. Utöver den uppenbara ekonomiska förlusten för företagsledningen och ägarna drabbas även andra intressenter såsom bolagets kreditgivare, leverantörer, kunder, staten och naturligtvis bolagets anställda. Följderna av en företagskonkurs kan dock mildras om företagets intressenter får en möjlighet att förbereda sig. Genom att förutse ett företags konkurs ges intressenterna en chans att vidta nödvändiga åtgärder för att skydda sina intressen.

It has become fairly common for a company to outsource one or several of its logistic activities to a party separate from the business of the company itself. Since the original agreement usually involves two parties, the seller and the buyer, the logistics company is called the third party. The relationship between the outsourcing company and the third party varies in form and in depth but can sometimes be very close, almost to be considered a joint venture. When the co-operation between the two parties includes more than just one separate logistic service and the third party adapts its business to a certain extent to his principals needs, it constitutes third party logistics. If the logistics company, or a party employed by it, becomes insolvent when having the entrusted goods in his possession questions may arise concerning the right to the property.

Sambandsanalys av surveydata kompliceras av förekomsten av slumpfel och metodeffekter i de avgivna svaren. Dessa felkällor kan leda till betydande över- eller underskattning av sambanden mellan undersökta variabler, och riskerar att leda till felaktiga slutsatser.En sedan länge känd metod för att estimera och kontrollera för slumpfel och metodeffekter i enkätdata är den så kallade Multitrait Multimethod-metoden (MTMM). Nackdelen med MTMM-metoden är att den kräver att varje fråga som ska analyseras ställs minst tre gånger i samma enkät, vilket gör att ansatsen i praktiken oftast inte är möjlig att tillämpa. Sedan 2012 finns dock ett verktyg, SQP 2.0, som gör det möjligt att skatta slumpfel och metodeffekter i enkätdata utan att genomföra MTMM-experiment. Den här uppsatsen utvärderar prediktionerna från SQP 2.0 på en enkät om arbetslivsrelaterade frågor besvarad av svenska och brittiska respondenter.

During the Swedish banking crisis in the early 1990?s, the government paid out 65 billion Swedish kronor to save Swedish banks from bankruptcy. In the process, two banks left the private sector to be taken over by the state. This thesis builds on a study from 1998 in seeking to quantify the financial end result for the Swedish government from the subsidies. Taking a cash flow approach and accounting for the time difference, it starts with the money paid out during the years of crisis and subtracts the money that has since been returned to the government by successful management of the relinquished assets.

The purpose of this study was to examine by means of Eysenck Personality Inventory (EPI), the relationship between Neuroticism, and self-rated eating problems. Altogether 105 respondents, mean aged 42,3 years, including 11 men and 94 women, participated by answering an Internet-based questionnaire comprising three different sections. Neuroticism correlated with self-rated eating problems (r=,468, p.

An employee that informs on illegal or unethical behavior in the workplace is what has been called a whistleblower. Employees that have become whistleblowers have often faced tragic consequences, like threats from the organization, unemployment, bankruptcy and divorce. The purpose of this paper is, on the basis of different ethical perspectives to describe the justification of the whistleblowing phenomenon and apply this to the Swedish whistleblower Ingvar Bratt who ?blew the whistle? when he found out that Bofors AB, the company he worked for, were smuggling arms to the countries Dubai and Bahrein. The method that has been used in this paper is what Björn Badersten call a normative ?givet att?- analysis.

New companies go public through Nasdaqs growth market First North constantly. The reasons for going public are many, and the interest at the moment is big. There are different ways to go public, the most common being the traditional IPO. This study is about the companies that have been listed on Nasdaq First North between 2008 and 2013 through traditional IPO, or by RTO (reverse takeover).The differences between these two ways of going public are that the IPOs are reviewed more thoroughly by Nasdaq and the market. This makes the study interesting, as the RTOs go public in a faster way, and avoid the review from outside parties largely.

This study compares the sample variance of the mean in a simple random sample (SRS) and a systematic sample from a surface. The study also compares the prediction error variance in a SRS and systematic sample from a random field. Recommendations are presented on which method to use in the clearance and exemption process in the nuclear industry. The results indicate that quadratic systematic sampling outperformed SRS in most instances and proved to be especially efficient in the presence of a long-ranged covariance function and high sampling intensity (i.e. short distances between observations).

I denna uppsats tillämpas multipel regressionsanalys med syfte attpredikera huspriser i Falun. Data som består av dels priset vid ett antalhusförsäljningar och dels ett antal eventuellt samvarierande förklarandevariabler analyseras. Två lämpliga, modeller som på ett så precist ochenkelt sätt som möjligt förutsäger en kommande försäljning av ett hus tasfram. I den första finns en mäklarfirmas utropspris med som förklarandevariabel i den andra inte. Prediktionsförmågan för de båda modellernablir inte användbar i praktiken men bättre då utropspris finns med.

A group of scientist, called the council of democracy in Sweden made a predictionabout members of political parties, in 2013 members should not exist. In this essaythat statement going to be questioned. It shows that most of the political parties losesmembers in Sweden. The only differences from year 2000 and now is that in 14 yearsthe parties has lost 65000 members, between 1991-1999 it was about 220000members. Something has changed.

In the beginning of the 21st century, a number of scandals were pointed out in the US. Enterprises like WorldCom and Enron went into bankruptcy, and inaccuracies in their account were made public. This led to the fact that a new law, SOX 404, was established in the US. The law says in its whole that enterprises must have better control of their internal accounts.The aim with this paper is to examine how the surrounding world of an organization with stakeholders as well as other surrounding elements, affect or force an organization to change, and how a changing process is introduced and accomplished.We carried through a survey as well as interviews at the actual organization. Furthermore, we investigated why the change has come into practice as well as attitudes and opinions towards the change, and lastly, how the changing process has been accomplished.
