Exercise pens as an environmental enrichment for laboratory rabbits
This thesis analyzes the effects of different fertilization strategies on forest management at Holmen Skog in Umeå district. Harvesting volumes, net present values and fertilization intensity are presented for each fertilization scenario. The planning reserve (percentage area older than minimum final felling age) was also analyzed in this study.The thesis covers the analysis of five different fertilization scenarios, varying in fertilization intensity, from no fertilization at all, to fertilization at every harvesting operation (thinning or final felling). A sub-study was also carried out so the reader in detail can see how the different fertilization scenarios affect individual forest stands of different nature. The analysis has been done with the planning tool PlanWise, which is an application of the Heureka analysis and planning system.
En granskning av det internationellt använda frågeformuläret International Outcome Inventory for Hearing Aids (IOI-HA).
Assessment of hearing aids can be done by inventories. The result of the inventories can show the patients need and how the hearing aids works in the patients daily life. The result of the inventories can be influenced by the difference in languages and the cultures. The inventory IOI-HA should not be sensitive to those factors.The aim of this study was to compare and analyse material, method and to report and analyse the result from a pilot study made at Sahlgrenska University.The result showed that IOI-HA is a natural inventory which is able to be used internationally. The four studies in England, USA, the Netherlands, and Germany showed that the psychometric properties are similar across languages and cultures.
Köp av skogsfastighet : en fallstudie
The price of Swedish forest properties has gone up by 77 percent during the past five years. Amongst private forest managers the high price level signals optimism and confidence for the future.
Many forest owners manage large capital in the forest and a planned economy is to a larger extent demanded to achieve a positive economic result. Forest is long-term and to maximize a single year without planning for the years to come results in less optimization of the parameters available to achieve a favourable economic result.
This case study investigates the investment of two forest properties situated in Götaland.
The management of the forest has been planned for both properties during a period of ten years.
Local forest governance and benefit sharing from reduced emissions from deforestation and forest degradation (REDD) : case study from Burkina Faso
Africa is one of the regions most affected by climate change. However its forests are important carbon sinks for the whole world, and if recognised as a global public good, could be conserved and contribute to green house gas emission reductions. A global mechanism, Reduced Emissions from Deforestation and forest Degradation(REDD+) aims to help developing countries in reducing emissions from deforestation and forest degradation, and enhancement of carbon stocks. REDD+ strategies may, however exclude local forest dependent communities from forests in order to conserve and maximise carbon stocks, thus having a severe impact on local livelihoods. Therefore, how local communities can participate and share benefits from REDD+ is a key concern.This study investigates how three forest dependent communities in the Nazinon forest, in Southwest Burkina Faso could financially benefit from a REDD+ project.
Stormskador i stickvägsgallrade bestånd i sydvästra Sverige :
A storm in January 2005 felled 75 millions cubic metres of forest in South Sweden. Previous studies of wind damage in thinned stands indicated the importance of early thinnings. The risks of wind throw increased by increasing age and height of the stands. Previous studies also indicated increasing risk of wind throw along the strip roads. The aim of the present study was to investigate wind damage in Norway spruce stands in South Sweden in relation to time of the first thinning and different pattern of strip roads (width, length and direction).
Skogsvård hos privata skogsägare : vilka åtgärder utförs och av vem?
Many participants in the Swedish timber market procure raw material from private forest owners. They often also offer forest services to ensure reforestation after final felling. Selling silviculture services can be a part of creating a long term relationship with the landowner for future timber purchases. The Swedish Forest Agency monitors forest rejuvenation results in the entire country. In the latest survey (2006 - 2008) the proportion of approved regeneration area was 78%.
Orienterare, framtidens naturvårdare? : Inventering av markstörningar i samband med O-Ringen i Skåne 2014
As an increasingly rationalized forestry and agriculture have human interference in the form of tradition, grazing and use declined. There is a strong link between biodiversity and disturbance of the landscape. In sandy soils many insects and plants require exposed sand to survive while the disorder may contribute to seed dispersal in the woodlands. On behalf of O-Ringen Skåne 2014, a study of the interference from orienteering in sandy soil and the forest during competitions conducted. The aim is to clarify the interference of which orienteering runners contributes, through to inventory presence before and after the competitions in the bottom and field layer in three locations.
Prestation i traktplanering
This study was an assignment for the company Holmen which is located in the region of Örnsköldsvik, Sweden. The study was focusing on the responsibilities of a forestry planner during the planning season.
The study was investigating about how much time the planner spent in the office, in the car and out in the forest. Any other issues that would cause delays were also identified. To be more effective and to increase the number of objects to a district bank, a better preparation in the planning stage (for thinning?s or clear cuts) is needed as well as faster transition on to the next area.
Varumärkessamarbeten mellan LVM och EVM vid kategoriutvidgningar: En Fungerande Strategi?
This thesis examines the possible beneficial effects of a temporary cooperation between a national brand and a private brand. The main hypothesis suggests that if a national brand wants to make a category extension to a remote product category, it should be able to decrease its risk by affiliating itself with a private brand. The national brand should through such a brand alliance be able to borrow some of the flexible characteristics that a private brand possesses to increase its associations with the new category. The survey consisted of 800 questionnaires with different cooperations between a private brand (ICA) and two national brands (Tropicana and Bravo). These were handed out to students in the universities of Stockholm.
Energieffektivisering i kommun
AbstractThe Municipality Council decided in 2010 to develop a comprehensive energy efficiency strategy with financial and methodological support from Energimyndigheten (The Swedish Energy Agency). The strategy should include 3 major parts: an inventory of the 2009 energy use defining the current situation, the 2014 and 2020 goals for energy use, and an action plan for goal achievements. According to Energimyndigheten, the strategy must include all municipal administration premises, vehicles, and all majority-owned companies (as Laholmshem, the municipal housing company).The report describes the inventory work in order to obtain the 2009 energy use and the sources of information used. The inventory values are used as the base year values for the 2014 and 2020 goals. The inventory showed that information about the vehicles is dispersed in the municipal administration and no clear structure exists with respect to mileage and fuels used.
Berättelser om Sverige. En narrativ analys av nationellt identitetsskapande på Dagens Nyheters insändarsidor
AbstractIn this essay I discuss narrative in the reconstruction of national identity. I discuss exclusion as a side effect in thick identities. That means that thick national identities always exclude another part. From this I´ve discussed the Swedish identity and its effects in the European co-operation. Identity is a discourse that reconstructs linguistically.
Hybridmodeller för prediktiv modellering skapade med genetisk programmering.
Det finns idag ett stort behov av att kunna klassificera stora mängder data på ett effektivt sätt. Prediktiv modellering är ett område inom data mining där prediktioner kan utföras baserat på tidigare erfarenheter. Dessa prediktioner presenteras sedan i en modell. Avvägningen mellan tolkningsbarhet och träffsäkerhet är ett begrepp som beskriver hur träffsäkra modeller ofta är ogenomskinliga, medan genomskinliga modeller ofta har lägre träffsäkerhet. Detta är ett problem eftersom det finns ett behov av modeller som är både träffsäkra och tolkningsbara.I denna studie visas hur man kan gå till väga för att skapa en modell som har en träffsäkerhet i klass med en ogenomskinlig modell, men samtidigt har en högre tolkningsbarhet.
Vad har det med religion att göra? : En studie om elevers och Skolverkets mål med religionskunskapsämnet
This essay examines upper secondary school pupils as well as the Swedish National Agency for Educations views on the education in subject of religion. How they describe its purpose, what content the topic should address, how the education should be implemented and what influence the pupils should have over their own studies. This to examine how the views of pupils and the Swedish National Agency of Education correlate and to analyze how it possibly can affect the pupil?s motivation. The survey is conducted by semi-forging tured interviews and text analysis in order to ascertain the pupils and the Swedish National Agency of Educations opinions on the issues.
Södras gröna skogsbruksplaner ur ett landskapsperspektiv :
The aim of the "Green forest management plans" is to help forest owners to reach the
environmental goal of the forestry act. But are they able to do that? Is it possible to plan preservation of species on single estates? How do single-estate-plans differ from a landscape analysis and how can the landscape approach be used in operative planning? This work was initiated to give an answer to these questions.
This study was made in a landscape of 4200 ha in Östergötland county, south-eastern Sweden. A lanscape analysis was made and then compared to the Green forest management plans in the same area. The nature conservation areas (areas that were set aside to be managed with environmenatl goals) differed quite a lot between the two alternatives.
Epixylic, forest-interior bryophytes in young stands : importance of local environmental variables, propagule sources, and distance to bordering woodland key habitats
The reduction of coarse, dead wood is considered to be the biggest threat to flora and faunain boreal forests. Extensive harvest of logging residues would increase this reduction evenmore. However, the role of dead wood created at final felling for boreal, epixylic species isstill largely unclear. It is therefore of interest to examine whether epixylic species inhabit thedead wood in young, boreal stands, especially species considered to be confined to forests inlate successional stages.The aim of this study was to investigate whether forest-interior species in fact can inhabitearly-successional forests arisen after logging. The study was conducted in young standsbordering dead wood rich woodland key habitats.
