Informationsflödets roll i avverkningskvaliten
The information flow is a very important process in an organization. It affects in a decisive manner the effectiveness of a task. It also has a major impact on the quality of the product or service for which the organization delivers to its customers. Lack of information may cause that important aspects are not given the required attention or even forgotten and can in turn lead to criticism from certification officials and lower customer satisfaction. The purpose of this study was to study how the information flow in Norrskog?s field organization is handled and how this affected the quality of the work performed and the feedback given to the contractors, The study is based on qualitative interviews with contractors, production inspectors and forest inspectors on all Norrskogs districts.
Ståndortsanpassning och produktionspotential för björk i Gävleborgs län
Large amounts of birch-timber are imported to Sweden, from particularly the Baltic States, since the domestic production can?t support the pulp industry. The goal of this study was to show the potential of birch and the area?s most suitable for birch production. The study was limited to Gävleborg County.
Using site characteristics, site index (SI) for birch was estimated on all National Forest Inventory plots in Gävleborg County.
Femtio Nyanser av Co-branding - En kvantitativ studie om effekterna av co-branding på konsumenters varumärkes- och produktutvärdering beroende av kvalitetssegment och hedoniska shoppingmotivationer
The retailing industry has an extremely high density of brands. In order to differentiate its offer, both retailers and suppliers, are constantly forced to come up with new ways to launch their products. A collaborative strategy between two brands is called co-branding, which means that both the private label and the supplier's brand are displayed on the new product packaging. Several studies have shown that a co-branding strategy is successful, but many operators are still reluctant to use co-branding in fear of long-term losses due to potentially damaged business relations. The objective of this study is to explain how the product- and brand related value for customers, retailers and suppliers is affected by co-branding between private labels and national brands.
Virkesproduktionen under 80 år i ett fältförsök i Dalarna med olika skogsskötselsystem
I Sverige är trakthyggesbruk med kalhuggning det dominerande skötselsystemetmen intresset för kalhyggesfritt skogsbruk har ökat de senaste åren. Alternativentill kalavverkning är omdiskuterade och kritiseras ofta för att inte vara lönsamma.Målet med detta examensarbete är att analysera ett långtidsförsök med olikaskogsskötselsystem och att diskutera eventuella produktionsskillnader. De fem skötselåtgärdersom undersöktes var 1) kalavverkning med plantering av gran och tall,2) naturlig föryngring under fröträd, 3) blädningsbruk, 4) dimensionsavverkningoch 5) orörd skog (referensyta). Fältförsöket ligger på Siljansfors försökspark iDalarna och anlades 1923. Alla försöksytor har en areal av 1 ha.
Visualisering ? ett verktyg för att illustrera långsiktiga konsekvenser av slutavverkning och naturhänsyn
Forestry in Sweden is currently conducted in a manner aiming at equating the production objectives and the biodiversity. To ensure that biodiversity is maintained, patches that are considered to be valuable now or in the future is saved in final fellings. How the tree retention areas will grow into the future forest stands is yet unknown.The purpose of this study was to visualize how different scenarios of natural consideration taken at final felling will evolve in a long term perspective, for two rotation periods. Projections of the forest conditions were executed with the decision support system Heureka and its applications PlanStart and PlanWise. The information about the projected forests was then used for the visualizations which were created in the software Visual Nature Studio.
Till synes orörd skog : naturvärden och kulturhistoria i Rekdalen under 400 år
Nature conservation has for a long time been founded on the assumption that high ecological values depend on low human impact. In Sweden this has led to forests with these characteristics being strictly protected from human influences. However, it is also known that historical land-use can enhance ecological values in forests. Mountainous forests in Sweden, which have not been affected by modern forestry, have for a long time been considered as untouched by people. However, forest history research has in recent years shown that even these areas have been used by people for a long period of time.
Contortatallens roll för virkesförsörjningen på Holmen Skog, Region Iggesund : konsekvensanalys av fyra hushållningsstrategier för contortatall
Large areas of Lodgepole pine (Pinus contorta var. latifolia) were planted in the 1970s - and '80s. The purpose of the fast-growing species was to increase growth and with short rotation periods allow a rapidly increased harvest level. Today a large proportion of the young forests owned by Holmen Skog, Iggesund are covered by Lodgepole pine and an active forest management is required to spread the harvested volume over time which is desirable by a market perspective. The purpose of this essay is to investigate the possibility of spreading the harvested volume of Lodgepole pine over time.
New Business Model for District Heating Firms Stabilizing the National Energy System with a Future Variable Electricity Production
The aim of this thesis is to develop a new business model for district heating and cooling firms which can contribute to a stabilization of the Swedish national energy system. The business model is developed for a district heating and cooling firm and is exemplified with Fortum Heat. The theoretical investigation around the topic creates a rigid base for following qualitative empirical studies. Osterwalder?s canvas for business model generation is used together with a Casual Loop Diagram to identify a number of business opportunities which stabilizes the national energy system.
Koalitioner - ett kostsamt fenomen? : En studie koncentrerad till Sveriges kommuner
AbstractSince the 2006 election the country of Sweden is governed by four Liberal and Conservative parties. Parties that by cooperating maintain power in office and forms a so called coalition. A coalition that not only can be seen at the national but also at the local level. According to pervious research coalitions that holds control of the seats in the government at the national level tends to increase the total expenditures compared to other types of government formations. Can a similar connection be seen at the local level? This the fundamental issue of this essay.
Alliansformation - relationen mellan Israel och USA
The special relationship between Israel and the US has been subject to questioning, and good many theories have tried to explain why it is so strong. The most common explanation is rooted in the school of realism, where strategy and national interest decide who one's ally is. This essay aspires to examine another possible reason for allianceformation; identity. Several books, which make for the theoretical backbone of this study, have been written on the subject of sharing beliefs, identifying with others and the consequences of this. The question being asked is whether Israel and the US actually share beliefs and, if so, which ones.
Koldioxidlagring - realitet eller utopi? : En komparativ fallstudie med syfte att undersöka potentialen för koldioxidlagring i geologiska formationer och biologiska sänkor och dess förmåga att bidra till hållbar utveckling
To curb greenhouse gases and mitigate climate change is one of the biggest challenges human society face today. Carbon dioxide (CO2) has accumulated rapidly in the atmosphere as a consequence of burning of fossil fuels and deforestation. The aim of this study is to explore two methods to store carbon dioxide in geological formations and biological sinks. The aim is also to discuss the two mitigation options from a sustainable perspective and whether it can lead to a better environment and benefits for local and global societies. The research questions are: Which method to store carbon dioxide, geological or biological, is the most effective? Which method to store carbon dioxide, geological or biological, has the greatest potential to promote sustainable development for local communities?The method used is a comparative case study and presents four case studies that explore the potential for CO2 storage offshore in Norway and Brazil; and in tropical forests in Mexico and Brazil.
Granföryngring på tallmark, hur ofta förekommer det? :
This survey was made during the summer of 2004 and the spring of 2005, on commission
from the National Board of Forestry.
The aim of this report was to investigate how often Norway spruce (Picea abies L. Karst), is planted on poor Scotch pine (Pinus Silvestries) sites and if it affects the yield of Norway spruce? In order to investigate this, data from 29 stands witch had a lower site index than T24 was collected. The investigated stands were situated in the southern-eastern Sweden. In 20 plots in each stand, the highest tree, age, number of seedlings, site index and tree species per stand were measured.
Effekten på nedbrytningen av rötter vid tillförsel av ammonium sulfat i en granskog i sydvästra Sverige
Decomposition of organic matter is a critical process in the ecosystem, which involves many essential biotic and physical parts. Decomposition is therefore an important process both above and below ground. The rate of decomposition is dependent of many environmental factors for example: pH, moisture and supply of oxygen. The decomposition can therefore be affected by large scaled environmental influences, such as acidification and climatic changes. The root litter in the forest is in different ways affected by acidification, liming and manuering.
Kontextorienterad ämnesrepresentation: abstracting av spelfilm för Internationella biblioteket
The aim of this thesis is to examine how a context-specific form of abstracting of fiction film developed in relation to the cultural policy of Internationella biblioteket IB, theoretically can be motivated and practically shaped. The background of the cultural policy of IB is analysed and theoretical standpoints and problematic aspects regarding subject representation discussed. Theories which claim intersubjectivity as an ideal for subject representation and searches for objectivity in the process of subject analysis are criticised in light of the concept of interpretation as the only means to produce meaning and subjects in relation to fiction. Birger Hjørlands context-oriented theories of subject representation are used to theoretically motivate the context-specific form of abstracting. To suggest how a practical framework for abstracting can be created, film theoretical models of interpretation are examined in relation to the field of subject analysis and formal criteria of abstracting.
Skogsskötsel för att minimera stormfällning över järnväg :
The society of today is dependent of secure transports and deliveries of electrical power. Interruptions in different activities because of fallen trees cost a great deal of money in form of reparations and claimed damages for transport companies and electrical suppliers. Fallen trees along some railway sections are a severe problem. For instance, to repair the damages of the storm of week 5 year 2002, costed 2 800 000 SEK for the line region of Hässleholm. Today, the Banverket railroad company has no norms in general for how close to the railway the forest is allowed to grow.
