Studie av miljökonsekvensbeskrivingar till detaljplan : En jämförande analys av fyra MKB

When the local authorities establish a plan for land use planning, they have to judge if the influence on the environment could be of such a grade that they have to make a special Environmental Impact Assessment (EIA), following national laws and EU-directives. The laws for the process in Sweden is set by the Swedish Parliament, with advisory given by the central government authority, the National Board of Housing, Building and Planning, Boverket. For EU, the laws is set by the European Parliament and the Council. The laws and directions for this process have been changed for Sweden in recent years, and the aim of this study was to compare the contents of three different Environmental Impact Assess¬ments to see if there has been any change in appearances and content in later years, as well as to see if different municipalities and authors have effect on the EIAs. According to different studies some of the EIA done are without insufficient focus on main environmental issues in the EIA, or even that some information is missing.

The effects of mother trees and site conditions on the distribution of natural regeneration establishment in a Bornean rainforest disturbed by logging and fire

In the tropics, logging and wild fire can result in degraded secondary forests with lower biodiversity than in the natural forest. One way to limit forest degradation is to rehabilitate the present large areas of secondary forests. However, there is a lack of knowledge concerning the ecology of tropical tree species and further studies would be advantageous for future rehabilitation efforts of degraded rainforest. The objective of this study was to investigate how mother trees in secondary forest and different site factors affect the abundance and spatial distribution of natural regeneration of non-pioneer tree species in a tropical rainforest in Sabah, Malaysia. The study took place in the INIKEA Forest Rehabilitation Project area, which suffered from wild fire in 1983 and has been selectively logged over both before and after the fire. Natural regeneration and site variables were inventoried in plots, while mother trees were inventoried in the whole survey area.

Varför slår han? : En integrativ forskningsöversikt om de bakomliggande orsakerna och vad som kan göras åt det

Today equal representation between the genders in parliament is something to be desired. One way to reach the goal of equal representation is by using quotas. The purpose of the study is to research the lack of equality in elected institutions by using a perspective on qoutas.  The study also seeks to find answers to if using quotas is a good method according to gender studies. A text analysis is being used to find reasonable solutions to the study´s presented complivations.  By analyzing different texts about quotas some of the more common arguments in the discussion about using quotas in parliaments were highlighted. Some of the more frequent arguments to implement quotas are that it would be more just but also that women and men may have different interests, experiences and therefore equal representation would be a question of resources.

Naturen-Minnen från en kvällsvandring

Naturen är ett undersökande arbete i att uttrycka och materialisera en stämning baserat på minnen från en kvällsvandring. Jag gestaltar upplevelsen och materialiserar den i textil. Genom att undersöka möten mellan olika textila tekniker vill jag skapa en kollektion som ger en förnimmelse av min naturupplevelse. Text ur Caroline Ringskog Ferrada-Nolis bok Naturen har varit utgångspunkt vid uppbyggnaden av kollektionen. Resultatet är en dynamisk textilkollektion för hemmiljö som innehåller digitaltryck, ausbrenner jacquardväv och en stickad struktur.Nature is an exploratory work on expressing and materializing a mood based on the memories of a night walk.

Det gör ont när stockar spricker!

The aim of this study was to provide SCA Forest Norrbotten District with material to assist in their work towards decreasing the frequency of bucking splits in their saw timber logs. SCA Forest supplies the Munksund sawmill with pine timber. Periodically the sawmill experiences problems related to bucking splits in their logs. The purpose of this study was to find an available method to measure the occurrence of splits directly on incoming timber. The ambition was also to gain some knowledge about possible variations between different logging crews in terms of split frequency. If possible, this information could be used to investigate if certain crews produced more splits than others, and thereby making it possible to provide feedback to the logging machine operators. The study consisted of two major parts, a literature review, and a practical sawmill study.

"ESS avgörs i Bryssel": Nätverk söker förankring i institutionell beslutsstruktur

This paper aims at describing and explaining the bi-and multilateral negotiations that are, and have been, taking place between Sweden's chief negotiator Allan Larsson and European countries, and within the EU institutions in Brussels, in order to seek support for the Swedish offer to host the European Spallation Source, ESS. It applies a case study method using political science theories ? governance and government ? and to a large extent information from the involved actors in the policy process. The paper also presents a constructive position, in showing how the negotiations on ESS can turn into a process leading to a decision on the construction of this research facility. ESS is negotiated in networks on bi- and multilateral levels consisting of European research representatives and financiers.

Reproduceras genus i religionsämnets läroböcker? : En diskursanalys över två valda läroböcker för religionskunskap på gymnasieskolan

Teaching materials are a constant matter of discussion as they represent the school curriculum and what the students are reading in the classroom. Within religious studies in upper secondary school, a new approach emerged since the new curriculum from 2011, which is to interpret religion in relation to gender. This study aimed to see which gender performances two selected teaching materials represented, in both their texts and images. This study was performed using both discourse analysis for the texts and content analysis of the images. The study showed that traditional gender performances appear both in the chapters that touched human identity and also ethics and morals, and also in the chapters that touched the world religions.

Hur påverkas VD : ns belöningssystem av ägandet? ? en studie av svenska noterade bolag

There is a strong debate in the media about the CEO compensation in the listed companies and whether they deserve their high rewards. Many previous studies have shown differences in the reward system depending on the ownership structure, mostly testing for only ownership concentration or ownership category. This study aims to investigate how the influence of the owners affects the CEO reward system, testing for both the level and the structure of the reward. The sample used in the investigation is Swedish listed corporations and consists of 251 observations. A survey was also conducted but due to low response rate and because the answers are not representative for the whole sample the survey will only be used as an illustration.

Förekomst av törskate (Cronartium flaccidum, Peridermium pini) på tall (Pinus sylvestris) i relation till markfuktighet och fältskikt : en studie om 2000-talets törskateepidemi i norra Sverige

Resin-top disease is a rust fungi that occurs both as a host alternating form, Cronartium flaccidum G. Winter., and as a non-host alternating form, Peridermium pini Pers. The host alternating form can use a variety of hosts but the most commonly used species in the boreal forest is Melampyrum sylvaticum. In Scandinavia the Resin-top disease infect Scots pine, Pinus sylvestris L. The fungus infects the needles through the stomata and then grows through the branch to the stem where it strangulates the vessels transporting water and nutrition to the treetop, which kills the top.

Goliatmusseron (Tricholoma matsutake) - kräver den en kontinuitet av träd? :

Modern forestry management may disadvantage some mykorrhiza forming fungi because; they are dependent on late successions and cannot survive the constantly recurring breaks in the continuity of their host tree. For this study the specie goliatmusseron (Tricholoma matsutake) was chosen to investigate this possibility. In Sweden T. matsutake is found in greatest amounts north of Örnsköldsvik on glacifluvial sandy soils in association with pine trees and reindeer lichens. Seventy two forest stands where the specie previously had been found were studied; 62 in the northern part of Sweden and ten in the southern. Several indicators were studied to find out if these stands have had a continuity of living trees.

Bokhögstubbar i Klåveröds strövområde : utbredning, egenskaper och betydelse för rödlistade vedlevande skalbaggar

Lack of dead wood is the main cause of decaying or loss of populations for many forest species. To increase the amount of dead wood is a prerequisite to maintain biodiversity in forests of northern Europe. In summer 2006 the recreation area Klåveröd, at Söderåsen in Skåne, Sweden, has been inventoried for high stumps (snags) of beech, (Fagus sylvatica). The result of the inventory has been compared with data of the real estate and forest management directories from the owner, region Skåne. The results have also been matched with the results from an inventory of saproxylic beetles in 2005, performed with windowtraps on selected snags both in the area and the adjacent national park Söderåsen. 594 snags were found on 747 ha.

Kapitalstruktur i svenska aktiebolag : En studie om påvisade faktorers egentliga påverkan på kapitalstruktur

In order for companies to be competetive on the market, there?s a need of capital. If a company is in a need of capital to make major investments and isn?t able to prioritize internal funding, the priority will be external financing with safe securities; loans. How companies should prioritize the allocation between equity and debt, which together form value, leads us to the subject of capital structure.

Sortimentsinriktad avverkning

Forest enterprises have always searched for ways to improve efficiency. For the past few years there has been an emphasis on stock-keeping levels. Increased demand for fresh round timber and the need to decrease the amount of tied-up capital has made the forest industry reduce its inventory levels. This has brought on a higher demand on the timber supply from the forest management districts concerning both delivery in time and assortment output. As a result, the flow of timber has fluctuated a lot with serious consequence for the timber supply during 1994.

Uteblev effekterna av 9/11? En analys av förändringen inom EU:s samarbete mot terrorism utifrån historisk institutionalism

In 1992, the European Union began institutionalizing the cooperation against terrorism within the EU structure. Since then, this cooperation has gone through a number of changes. From a historical institutionalistic point of departure we explain these changes by identifying sources of institutional resilience and institutional change. Based on these results, we were able to pose hypotheses of when and what category of change was most likely to take place.The results show that the cooperation against terrorism within the EU was most likely to remain stable because of strong sources of institutional resilience. If change would occur through an increase in the sources of institutional change, it was most likely to be of a less extensive category.

Spatiella mönster och lager av organiskt klor och klorid i barrskogsjord i sydöstra Sverige

The concentration and storage of organic chlorine and chloride were determined in soil, to a depth of 40 cm, in a coniferous forest in the Stubbetorp catchment area in south-east Sweden. Also, the spatial distribution of the two forms of chlorine was determined. Soil samples were collected at 49 of the nodes in a grid with approximately 105 m between the nodes. The analysis of spatial variability suggested that no spatial autocorrelation was present either within the variable organic chlorine or chloride. This means that no sample was more influenced by another nearby sample, as compared to other samples further away.
