Besökarstudie i Kilsbergens rekreationsområden : en metod för att utveckla rekreationsmöjligheter på Sveaskogs marker

In this Master thesis an effective method is presented to find out what is requested in a forest or outdoor recreation. The aim with the study is to find out how Sveaskog can increase the general interest for experiences in nature and improve the access for recreation. Some questions that have been used to answer this purpose are: Who is visiting/not visiting the recreation area? How is it possible to increase the number of visits? The study is carried out in Kilsbergen and mainly centered around Ånnaboda, which is the natural place for people to meet at and undertake recreational activities. The method that is used is a mail-survey that was sent to visitors and people living in Örebro. People living in Örebro represent potential visitors who live close to the recreation area.

A comparison of two certification schemes for dairy cow welfare in relation to resource-based, management-based and animal-based measures

Traditionally risk-based measures have been used to assess animal welfare in legislation and certification schemes. With increased knowledge and research, debate today tends to focus on and advocate the use of animal-based measures. However this is not a panacea for welfare and the most sound conclusion should be that assessment of animal welfare needs both. The aim of this thesis is to identify the points that need to be taken into consideration to find the optimal balance in the use of input and outcome measures according to the aim of the assessment and how these should be applied when designing a certification scheme? To answer this, a comparison of the use of resource-based, management-based and animal-based measures in two certification schemes for dairy cow welfare, Freedom Food (UK) and Svenskt Sigill (SWE), was made.

Stamskador i gallringsbestånd

This study was conducted on a property with a thinning machine team. The purpose was to investigate in which machine, the harvester or the forwarder, that caused most damage to the trees in six different stands. Different factors, related to the damage frequency in the stands, were checked out. For example: basal area per hectare, thinning strength, tree diameter and the rate of production. The harvester drivers were also interviewed about how, when and why stem damages occur and how to minimize them. The study stated that 4.3 percent of the trees were damaged. Out of these 88 percent was caused by the harvester and the rest, 12 percent, by the forwarder..

En undersökning av VaR-modeller med Kupiecs Backtest

SAMMANDRAGHistorisk Simulation, Delta-Normal och RiskMetrics prestation utvärderas med hjälp av Kupiecs Backtest. Value at Risk (VaR) beräknas med tre olika konfidensnivåer utifrån Affärsvärldens Generalindex och HSBC kopparindex. Utifrån överträdelser från verkligt utfall undersöks vilken VaR-modell som estimerar marknadsrisken bäst. VaR-modellernas prestation jämförs, och i analysen utreds hur konfidensnivå och tillgångars egenskaper påverkar VaR-modellernas prestation. Resultaten visar att Historisk Simulation presterar bättre än Delta-Normal och RiskMetrics på den högsta konfidensnivån vilket troligtvis beror på att RiskMetrics och Delta-Normal antar normalfördelning.

Brottslighet, psykosocial belastning i barndomen och risk för våld : Könsskillnader hos rättspsykiatriska patienter

Rättspsykiatriska patienter är en grupp med mycket psykosocial belastning i barndomen och mer forskning behövs kring bland annat huruvida det finns samband mellan denna psykosociala belastning, framtida brottslighet och bedömd risk för våld. Denna studies syfte var att jämföra brottslighet, psykosocial belastning i barndomen samt initiala riskbedömningar gjorda med HCR-20 på kvinnor respektive män vårdade vid Rättspsykiatriska Regionkliniken i Sundsvall. Vidare undersöktes ifall förekomst av psykosocial belastning i barndomen korrelerade med bedömd risk för våld bedömd med HCR-20 eller med brottslighet hos patienterna. Studiens sampel bestod av 10 kvinnor och 39 män varav majoriteten vårdades enligt LRV. Data samlades in från journaler, rättspsykiatriska undersökningar och domar samt genom enskilda intervjuer.

Att vända en dålig trend

There is an irregularity in the interregional migration in Sweden. An increasing proportion ofthe population is drawn to the metropolitan areas, which creates problems for the smallermunicipalities and towns when their population declines. At the same time, our whole societyis faced with a great challenge: we need to redirect towards a sustainable development, wherethe environmental issues are discussed and dealt with to secure that all present and futuregenerations are given equal opportunities to live a good life.The aim of this study is to, focusing mainly on the environmental dimension of thesustainability concept, examine the attractivity of housing with sustainability claims. Toanswer this, three research questions were used:? Was the migration motive to reduce their environmental impact a part of the decision tomove, among migrants who had moved to housing with sustainability claims?? If the motive was a part of the decision, how much impact did it have compared to othermigration motives?? Which factors in housing aiming at sustainability are considered important by peopleliving in housing with sustainability claims?The research questions have been answered using quantitative data, gained in the form of selfadministeredquestionnaires which were distributed in four different residential areas withsustainability claims in the county of Västra Götaland, Sweden.

Effects of palmitic and stearic acids supplementation on milk yield, composition and milk lipolysis in dairy cows

When facing the fact that high yielding dairy cows has an increasing energy requirements, the practice of adding lipid supplements such as concentrates rich in palm oil and/or palm oil industry by-products become more common. Palm oil containing high levels of C16:0 causes high levels of free fatty acids (FFA) which are linked to larger milk fat globules (MFG) which affect the reaction of lipolysis resulting in rancid flavour and processing problems. Instead of using palm oil, rapeseed oil rich in C18:1 C18:2 can be used. In order to evaluate the effect of added C18:0 and C16:0 on milk lipolysis, 30 Swedish Red lactating dairy cows including 15 multiparous (MP) and 15 primiparous (PP) cows were randomly divided in three groups resulting in 3 10 cow-groups (5 PP and 5 MP cows per group) and fed one out of three concentrate mixtures: control (C), a standard concentrate mixture with no fat added; palmitate (P) as C plus the addition of palmitate methyl ester (10 % in DM basis); and stearate (St) as C plus the addition of stearate methyl ester (10 % in DM basis). Milk yield was registered, and milk samples were collected and analysed for milk composition, FFA content and size of MFG.

Spatt relaterad till tarsalledens vinkel

The effectiveness of Phlebiopsis gigantea to prevent spore infections from Heterobasidionannosum and Heterobasidion parviporum on hybrid larch stumps were investigated in fivestands in southern Sweden. All sites are former forest land and the age of the trees wasbetween 9 and 13 years.The study was implemented in August 2010, a month where spore dispersal should be great.The five sites were located in previously un?thinned monocultures of hybrid larch. The sporeload in the air was studied with the help of spore traps from three different tree species;Norway spruce, Scots pine and hybrid larch. A total of 146 spore traps, evenly distributed inall five sites were analyzed.

Downloading and filesharing through Peer-to-peer networks: the copyright versus the free access to the cultural products

The ?peer to peer? (P2P) is a technology of downloading and filesharing between online - Internet - users by the mean of specified software. Since June 1999, the Napster software has made the happiness of millions of individuals who used it to obtain and share free audio files Mp3. Rapidly, the major recording companies have prosecuted the Napster Company and managed to force it to close down. They were arguing against it for it is supporting the development on a large scale traffic of files protected by copyright and thus was threatening the whole music and movies economic world.

Den svenska CleanTech-marknaden : aktörer och finansiering

This thesis describes and examines a new line of business, CleanTech. CleanTech comprises a wide range of different types of companies and is not yet well defined. In this thesis only the Swedish market is considered, and a variety of players on the market are included to give the most extensive picture of the current situation. Recent research shows that a gap has arisen between governmental financing and private equity-investments in CleanTech-companies. This gap occurs mainly in companies in expansive phases and causes problems both for the companies and for the line of business as a whole. To investigate this gap the Swedish CleanTech-business is described in terms of earlier and existing financing, age and size of the companies and their turnover and profit.

Kontroll för ökad kvalitet - mallar för kontrollplan-PBL, egenkontroll samt riskanalys

There are problems with poor quality, poor scheduling and poor working climate in the Swedish construction industry. Many parts have been involved, trying to solve the problem.This spring a new planning and building-law becomes final. In this law, the requirements set on the controls are greater. Hopefully this will lead to fewer construction errors. The requirements set on the working environment have also increased, forcing consultants and contractors to focus on safe workplaces.For each project requiring a building permit, an inspection plan has to been drawn.

Att försäkra eller inte försäkra - det är frågan : En studie av försäkring ur ett aktieägarperspektiv

Bakgrund: Alla företag utsätts för risk och en bransch med mycket stor riskexponering är flygbolagsbranschen. Hur risken än hanteras innebär den alltid en kostnad och för att aktieägarvärdet ska bli så högt som möjligt gäller det att minimera denna kostnad. Vilka huvudsakliga risker försäkrar sig passagerarflygbolagen mot? Vilka är motiven till att de försäkrar sig? Är hanteringen av försäkringsbara risker i överensstämmelse med ett aktieägarperspektiv?Syfte: Syftet med denna uppsats är att utifrån finansiell teori analysera passagerarflygbolagens användning av försäkring som riskhanteringsmetod. Analysen sker utifrån ett aktieägarperspektiv.Genomförande: Studien bygger på intervjuer genomförda med försäkringsansvarige på fem olika flygbolag.

Fördjupad miljöriskbedömning av förorenade markekologiska system. : Integrering av kemisk, toxikologisk och ekologisk information.

AbstractThe research project Liberation, supported by the European Commission under the Environment and Sustainable Development Programme (Fifth RTD Framework Programme) aimed at developing a decision support system for ecological risk assessment of contaminated sites has proposed a tiered system including the triad method. This method integrates contaminant chemistry and bioavailability analyses with observed ecotoxicological effects in soil and groundwater. In this study the triad method was used to perform a risk characterization of a former surface treatment and metal industry, now used for the student union buildings of the Mälardalen University in Eskilstuna, Sweden. On the site, high concentrations of copper, zinc and nickel have been detected in the soil in a preliminary investigation of contaminant levels with XRF. For performing the risk assessment of the site according to the triad method, contaminant bioavailability, soil metal concentrations and soil toxicity were determined and an ecological assessment was carried out on four selected soil samples (one reference soil and three samples with low (B), medium (C) and high (D) contaminant levels). Contaminant bioavailability was measured through leaching (ISO TC 190/S7) and biouptake tests (DGT).

Moderbolagets ansvar för dotterbolagets skulder : Avseende stödbrev och ansvarsgenombrott

Stödbrev utfärdas av ett moderbolag till en koncernextern part då ett avtal skall slutas mellan stödbrevsutfärdarens dotterbolag och stödbrevsmottagaren. Uppsatsen redogör för hur stödbrev fungerar och dess uppbyggnad. Det undersöks också vad det är för bakomliggande mekanism som förklarar hur avtal kommer till stånd och vilken betydelse det får att gemensam partsvilja mellan utfärdare och mottagare inte finns om stödbrevets rättsliga innebörd. Eventuellt kan Grönfors modell om avtalsgrundande rättsfakta vara en förklaring på avtalsverkningarna. Uppsatsen undersöker också institutet ansvarsgenombrott.

Attitudes towards hedging by diversified and non-diversified farmers : a comparative qualitative study

Deregulation on the market for agricultural products leads to a more globalised market with increasing price fluctuations. This, in turn, places the farmer in positions influenced by new risks but also improved opportunities. The farmers are faced by uncertainty in terms of financial outcome. To be able to utilise these new market conditions it becomes increasingly important for farmers to continuously follow the price trend, and to develop strategies how to manage the risks exposed by a volatile market. Farmers with different conditions perceive risk in different ways. Hence, their risk management behaviour will vary.
