Framtagande av en investerings- beslutsmodell för mindre tjänsteföretag

Problems:How would a decision model that takes into account more aspects and dimensions than just the financial aspect look for smaller service compa-nies? What aspects are important to consider in such a decision model?Purpose:The purpose of this master thesis is to develop a decision model based on previous research, to improve decision making in smaller service com-panies ? by considering perspectives that traditional investment calcula-tions ignore.Method:The study was qualitative and was based on both primary and secondary data. As data collection method for the development of the model we used literature search on previous research. The study?s primary data consisted of responses from five smaller service companies.

Beslutsprocesser och informationshantering ? en fallstudie inom en högskoleorganisation

The purpose of this thesis, was to study decision processes and the importance of information management in the processes within an academic organisation, which led to the work with adaptions according to the law of Equal Treatment of Students in Higher Education, (SFS 2001:1286). A general question was formulated concerning how different information- and knowledge flows interact within an academic organisation and its library during the decision processes. The questions at issue we have tried to examine, concern the factors that have influenced the participants´ choice of information during the decision processes, in their work of adapting the law of equal treatment, and how these choices have influenced the priorities that were made. The theoretical starting point was basically Cohen, March and Olsens Garbage Can Model. We also found the author Chun Wei Choo´s descriptions of organisations, as systems of information processing, useful for parts of our thesis, especially the parts that deals with the role of information management within the decision processes.

Trädslagsinverkan på markvegetationens utveckling i odlingsförsök med tall och contorta :

In the 1970?s it was predicted that in the beginning of the 21st century there would be a timber shortage in Sweden and a large scale introduction of the exotic tree species lodgepole pine started. An introduction of a foreign tree species means a risk of a negative influence on the forests ecosystem. Today, the stands that were established in the 70?s are middle-aged and the effect on the forest floor vegetation can be studied.

Potentiella arealer för ökad virkesproduktion i norra Sverige genom skogsodling med Pinus contorta var. latifolia, Larix sukaczewii, Abies lasiocarpa, Populus × wettsteinii och Picea mariana

Sweden is a country with few native tree species. According to Govt. 2007/08: 108, exotic tree species may be seen as an opportunity to increase the growth of tree volume in Sweden. Potential areas where explored In this work for cultivation with Pinus contorta var. latifolia Engelm., Larix sukaczewii Dylis, Abies lasiocarpa (Hook.) Nutt., Populus × wettsteinii Hämet-Ahti (tremula x tremuloides) and Picea mariana (Mill.) Britton et.al.

Lämpliga främmande trädslag för Kalmar och Mönsterås kommuner

This report concerns the for Sweden foreign tree species hybrid larch, hybrid aspen and poplar, and focuses on the area Kalmar and Mönsterås municipalities. The report shows that there are not only advantages with these species. The larch, the most common of the alien tree species has the greatest problems due to that its timber is difficult to sell in the area but also the Larch´s poor pulp quality and is more likely to be damaged by wildlife than the spruce is. Hybrid Aspen is much easier to sell and is used like regular aspen for match wood and textile pulp. Its disadvantage is the high cost for plants and to prevent damage from wildlife.

Utbyte av massaved och biobränsle i några typbestånd av Contorta :

The aim of this study is to describe a number of type stands of lodge pole pine in Norrbotten with respect on stem volume and total biomass. Further questions to answer is if there is stand characteristics that make the stands more suitable for pulpwood in early thinning, or if it is better to apply whole tree harvest. The study shall also give an indication if bio energy can be an economical interesting alternative for Sveaskog. Sampled trees represented the variation in the different stands. Five trees were selected from each stand to represent that stand. Stem volume and biomass (kg dry weight (DW) per hectare) for each fraction was calculated.

Planteringsförbandets inverkan på bestånd av contortatall (Pinus contorta var. latifolia) med avseende på volymtillväxt och virkesegenskaper

At the beginning of the 1970´s forestry feared an imbalance in the future wood supply. Because of this anticipated "timber slump" forest companies undertook a variety of measures to counter this. One of these measures was the introduction of exotic tree species. The choice finally ended up with lodgepole pines which were considered a fast growing tree species compared to our native tree species. Theambition for the new lodgepole pine stands were to run these with rotation periods of between 40-60 years, thus smoothing out the ?timber slump? that was anticipated.

Rum och rörelse - analys av alléns betydelse för människa och landskap

Within literature, politics and science, there is a claim that ?tree avenues are important?. But the question and the goal for this essay are to explore the pretext to how and why. Planting tree avenues is a 4000 year old tradition and they are a common element in the Swedish and Scanian landscape since the 18th century. They were first mainly planted by aristocratic land-owners or on their initiative, but since the 19th century also by farmers.

Bostadsspekulantens köpbeslut : En kvantitativ studie över bostadsspekulantens beslutspåverkan

Bakgrunden för denna studie är problematiken kring beslutsfattande. Tidigare forskning visar att en individ dagligen fattar en mängd medvetna och omedvetna beslut. Dessa beslut faller sig olika utefter vilka erfarenheter, preferenser och känslor individen har och hur detta påverkar individen vid köp av dyra sällanköpsvaror. Syftet med studien är att identifiera faktorer och personlighetstyper som influerar köparens beslut gällande dyra sällanköpsvaror..

Prestationspåverkan av flerträdshantering i klena gallringar

The aim of this study is to investigate how multiple tree handling harvesters perform compared to earlier developed standards. The study shows that multiple tree handling harvesters are more efficient in thinnings stands with mean stock volumes less than 0,12 m3fub per stock. The increased efficiency is different for different mean stem classes. In stands with a mean stem volume of 0,04 m3fub per stock, the increase can be as high as 40 percent while it is about 10 percent in stands with a mean stem volume of 0,12 m3fub. Comparisons have been done between stands that are felled with partly limbed stands and stands without partly limbed assortments. The difference in performance is clear and shows that the partly limbed assortments strengthen the multiple tree handling harvesters positive effects in low dimension thinnings.

NATURMINNENS F?RVALTNING OCH SKYDD: Inventering i V?stra G?taland

Natural monuments are natural objects with special protection due to their high natural value or cultural significance. The natural value is determined by the occurrence of signal species found on and near the natural monument. The law surrounding natural monuments has evolved a lot since the first ones were declared, and today the title natural monument can be replaced with the title tree with high conservation value. The title has come later and can sometimes overlap natural monument. Some natural monuments lack the qualities required to be classified as a natural monument or a tree with high conservation value, but have a cultural importance.

Betydelse av lövinslag, död ved och variation i träddiameter för artrikedomen hos småfåglar

Forest management contributes to the changes in forest structure by turning heterogenous forests of varied age into homogenous forests of similar age and thus affect bird species depending on different structures or habitats which are lost during forestry. In this report, a study was made to investigate how the amount of decidious trees, dead wood and variation in tree diameter affect bird diversity. The purpose of this study was to be able to give forest management guidelines to increase bird diversity. This study was conducted by investigating 65 transects in forests of different structure south of Linköping, Sweden. Along the 65 transects, birds were inventoried as well as the vegetation.

Demokratiförnyelse på lokal nivå : En studie av kommunala demokratiinnovationer

The main purpose of this study is to investigate to what extent municipalities in Sweden use democratic innovations to include citizens in the decision making process. Along there are three research questions:? What different forms of democracy innovations are Swedish municipalities applying in order to increase the civic participation between elections and what forms are dominant?? What potential influence in decision-making are citizens getting through these democratic innovations based on the results?? Based on the results ? in what ways is the democracy innovations used in municipalities challenging representative democracy? The method used to fulfill the purpose and answer the research questions is a web survey including 287 of 290 (in total) municipal websites. The theoretic framework includes a model which is called ?Smith?s ladder of participation? and is influenced by the research of Graham Smith and Sherry Arnstein.

Teknikens gråhåriga marknad - vi är här för att stanna : Vad påverkar äldres köpbeslut av ny teknologi?

This thesis aims to describe how enterprises can approach and reach older citizens inorder to sell new technology products. For that they need information about aspectsaffecting elderlies purchase decisions regarding these kind of products. The study isbased on 13 qualitative interviews where we have applied semi structured interviews andobservations of the elderlies behaviour towards an Ipad which we used as a study objectduring the interviews.The results of this study shows several aspects which affect the elderlies purchasedecision regarding new technology but it all comes down to one matter, lack ofknowledge. In order to overcome that obstacle, enterprises need to modify theircommunication strategy. They will be needing information about elderlies preferencesand their self-image, meaning how they perceive themselves which is connected to howreceptive they are towards new technology.

En vampyr i sitt liv : En studie om elevers syn på gymnasieskolans arbete mot diskriminering, trakasserier och kränkning

The representative democracy has become weakened during the last decades. At the same time the United Nations declared at the Rio de Janeiro meeting in 1992 that environmental problems can best be solved by involvement of all concerned citizens in decision-making. The main purpose of this study has been to examine if citizens panels is a possible way to involve citizens in environmental decision-making and what the outcomes can be. Furthermore the study has investigated what the participation has contributed to environmental politics and how representative the results have been. This has been carried out by investigating the Piteåpanel in the municipality of Piteå by conducting interviews.The result of the study shows that the involvement of the citizens in the decision-making influenced the environmental politics of the municipality.
