Hedging Core and Non-Core Risks: Evidence from Forestry and Paper Industry
A great number of empirical researches show that hedging is associated with higher firm value, particularly hedging interest rate and exchange rate. However, there is no clear support for value-added risk management hypothesis in the case of producers of commodities. Moreover, according to Shrand and Unal (1997), there are two types of risks, core business risks (or core risk) and homogeneous risks (or non core risks), which are based on a firm's comparative advantages with respects to the source of risk. Firm can earn economic profits for bearing core risks in which it has a comparative information advantage. Firm earn a zero economic rents for bearing non-core risks, where it has no advantage information than its competitors.
Etisk organisationskulturs inverkan på revisionskvalitet i företag
In today's society there is tougher climate both financially and time wise. Accountants working under tight deadlines leading to the compromise between quality and quantity in the audit process and them therefor are being guilty of so-called reduced audit quality, RAQ. Reduced audit quality involves intentional actions designed to somehow reduce the evidence contained in the audit. We examine in this study the impact of time budget pressure (TBP), underreporting of time (URT), ethical organizational culture and charismatic leadership has on the frequency of RAQ.Previous research has already shown that there are clear links between TBP and RAQ, between URT and RAQ and between ethical culture in organizations and audit quality available. Five hypotheses were designed to the study.

Människovana grävlingar som testdjur för grythundar. En studie om hur grävlingars beteende och fysiologi påverkas av hundars aggressivitet
In Sweden live badgers are used in tests in order to train and prepare earth dogs for hunting underneath ground. This has for several years causeddebate concerning the welfare of the badgers. It is questioned whether the purpose of the dog training, i.e. to reduce injuries in both dogs and prey, is worth the suffering that is reflected on the badgers. The aim of this investigation was to study 1) stress levels in badgers when used in earth dog training, 2) if the stress load differs when the badgers are exposed to dogs with varying aggression levels (low, moderate, high).

Research where personality in animals is studied is becoming more and more common. In this area there are different concepts like behavioural syndrome and animal personality and they usually talk about consistency in behaviour over time and situations. This consistent individual behaviour can be used as an indicator of how individuals can handle and adjust to new situations in the environment. Because of this, personality studies in animals are very important in animal welfare. In this study personality in dairy cattle in lose housing were studied.
Optimization of Western Blot for detection of cellspecific localization of DNA binding protein fromstarved cells (Dps) in Nostoc punctiforme
Cyanobacteria belong to the oldest organisms of our planet. They use photosynthesis to produce ATP and gain biomass from carbon dioxide. The cyanobacteria Nostoc punctiforme is a filamentous bacterium that consists of two different types of cells, vegetative cells and heterocysts. The type of cell it differentiates into depends on the media they grow in. In an ammonium-rich medium, the N.punctiforme consists of vegetative cells that differentiate into heterocysts when in the medium is changed to a low-concentration ammonium medium.

Grey-sided vole and bank vole abundance in old-growth forest patches of different size and connectivity
Vole populations in northern Scandinavia vary in cycles with peaks every third or fourth year as described by the National Environmental Monitoring Programme of small mammals (NEMP). Some vole species have declined in population numbers since the NEMP started in 1971, especially the grey-sided vole (Myodes rufocanus) which is nearly extinct in the forested region. Since small mammals are an important food source for several avian and mammalian predators, the decline in vole numbers is expected to have consequences for the whole food chain, especially if other vole species start to decline in numbers. This study tried to test the hypothesis that presence and abundance of M. rufocanus (a specialist species) and Myodes glareolus (a generalist species) can be predicted by patch size and connectivity of forest patches >60 years old with a minimum of 15% pine >100years old.

Frontningens Effekt på Försäljningen och Kundens Utvärdering av Butiken - Ett Experiment i den Naturliga Butiksmiljön
The research done in the field of product completeness/incompleteness is limited. The lack of research causes a knowledge gap in the retailing industry, concerning the actual effects on consumer choice, as well as on the overall store evaluation. This report tests the current theories of the subject, and also further aim to explore the effects of completeness/incompleteness on consumer's product choice. The results display an inconsistent effect on consumer's product choice when the completeness/incompleteness in a grocery store is tested. Some products benefit by being incomplete, while others show no such effect.

officials it also speeds up their work.
Tegnér i gymnasiet : En komparativ studie av Tegnérs utrymme i gymnasiala litteraturantologier samt läroplaner från 60-talet till våra dagar
The purpose of this study is to present a comparative analysis of seven literature anthologies for the Upper Secondary School, from 1968-2004, to investigate how much space Esaias Tegnér is getting and how many and which of his works that is presented in these anthologies.The study is set against the hypothesis that Tegnér is getting a reduced space in the anthologies because of his connection to Romantic nationalism, which after World War II has been associated to the themes and ideology of the National Socialism. In view of this I have asked myself if Tegnér is getting a reduced space in the literature anthologies for the Upper Secondary School. My study shows that this is the case.One can also see clear trends in a subjective approach towards the author. In the anthologies where Tegnér have had a strong prominent role, he is retaining his position even in later editions. Over the entire period of 1968-2004 he is getting a less prominent role, although he is generally presented as the greatest poet of his time.I have also examined the discussion of Tegnér during that period to see if you can find any connection between the discussion about Tegnér and the change his work gets in the literature anthologies.
