Detaljhänsyn efter slutavverkning : kvantitet och inverkan på framtida produktion hos SCA i Västerbotten

According to FSC (Forest Stewardship Council) shall at least a mean of 10 trees per hectare including riparian zones and other areas with high biological values be left in final felling. In addition large clear areas should not be created and all retained trees with high environmental value shall be spared. To leave trees in final felling means a lower cutting volume and hence a lower income from the cutting, but it also means that the production in the next generation becomes less because of competition. The aim of this study was to evaluate the effect retained trees have on the production in the new generation of forest, and to investigate if there is any way to lower this effect. The environmental care has also been estimated by the amount left in final felling.

Rissepareringens effekter på viltets nyttjandegrad av GROT

Successful forest regeneration is a prerequisite for sustainable forest management. Therefore, it is important to prevent browsing damage on the commercially important tree species Scots pine. In this study I have tested a new alternative way to increase the available amount of forage and increase the use of these resources by especially moose. The method is based on a slash treatment at harvest, where the accessibility of slash as forage is increased during final felling or commercial thinning by gathering the slash and putting the Scots pine slash on top of the slash piles. This study has compared the availability of forage, the amount of browsed biomass and the number of fecal pellet groups between conventional and slash treated stands after final felling and commercial thinning in southern Sweden.

Den gotländska Stridsyxekulturen : migration, interaktion eller regionalitet?

This one-year master's thesis investigates the late part of the Middle Neolithic on the island of Gotland. This thesis has been written without the influence of a singular theoretical pespective, and has therefore seen input from the processual, and postprocessual theories. By using several perspectives, an attempt is made to view the material remains used in the most objective manner possible. The specific aim of this thesis is to investigate whether the Mid-Neolithic inhabitants of Gotland were a part of the Corded Ware culture (or as it is called in Sweden, the Battleaxe culture or the Boataxe culture). Most recent literature has concluded that Gotland was never a part of the Battlexe culture, though this thesis has discovered many parallels with the mainland culture, including the production of similar Objects and ritual practices.

Generationsskräpsamling med explicit kontroll av hårdvarucache

This report evaluates whether an interpreted high-level garbage collected language has enough information about its memory behaviour to make better cache decisions than modern general CPU hardware.With a generational garbage collector, depending on promotion algorithm and generation size, around 90% of all Objects never leave the first generation. This report is based on the hypothesis that, because of the low promotion rate, accesses to higher generations are sufficiently rare not to benefit from caching.To test this hypothesis, we built an operating system with a Scheme interpreter in kernel mode, where the interpreter controls the cache. Generic x86 PC hardware was used, since it allows fine-grained control of cache decisions.Measurements of execution time in this interpreter show that disabling the cache for generations higher than the first does not give any performance gain, but rather a performance loss of up to 50%.We conclude that this interpreter design is not an improvement, but cannot conclude that the hypothesis is false in general. We suggest building a better CPU simulator to gather more data from which to make better caching decisions, moving internal interpreter data structures into the garbage collected heap and modifying the hardware to allow control in the currently rigid dimension of where data is cached---for example separate control of instruction and data caches and separate data caches for different areas of memory..

E-learning ? en utbildningsmetod och dess nytta

Companies that invest in e-learning have different expectations regarding the outcome of the investment. According to literature and articles it is common that companies see reduction of costs as the primary benefit with e-learning. Therefore we ask ourselves the question if companies have attained the expected benefit of the investment in e-learning and to what extent cost reduction have been a determining factor in the investments? The purpose of the thesis is to examine if companies that invest in e-learning have attained the expected benefits. We also want to examine what the reason for investing in e-learning is and if cost reduction is the primary reason for investing.

Media och dess inverkan : exponering av idealiserade könsroller och dess inverkan på unga människor

The purpose of this study is to examine the impact that idealised body images found in media have on the body-image and wellbeing of young men and women. The study was carried out using questionnaires based on the BAQ and HAD scales to examine the participants' views of themselves as well as symptoms of anxiety and depression. Time spent by the participants using different kinds of media, as well as their degree of social support, was used with the purpose of examining relations and differences in body-image between men and women. The questionnaire contained advertising images to examine whether short time exposure had any impact on the participants. In order to determine this, one half of the questionnaires contained idealised body-images, whilst the other half contained images without human Objects.

En ny teoris framväxt : en studie om teoriutvecklingen inom barndomssociologin

This essay aims to examine how theories within childhood sociology have evolved. The main questions are: Who are the central scientists within the field, what are their Objects of study and who are the intended recipients of their work? How can the origin of the theories be described? Which elements are central in the theories and have they changed over time? How can the theories be evaluated based on criteria of valid theories?The study was based on a qualitative literature review. Six scientists' publications were examined, ranging from the time of the theories establishment to present time. In the analysis hermeneutics and theories of scientific development were used to seek explanations.The main results show that the central elements in the theories describe childhood as a social phenomenon and a structural category.

Den europeiska identiteten Vem är europé enligt EU?

The main purpose of this thesis is to examine how the European Union through the Directorate- General (DG) of Education and Culture, are calling forth a constructed sense of European identity amongst the citizens of the Union.It is a discourse analysis, which can be described in twofold. Firstly, it is a mapping of the European discourse; i.e. how the European Union defines the identity it seeks to mobilise. Secondly, it examines whether or not there are similarities in the European discourse of identity and the traditional nation-building discourse of national identity.According to this thesis a European identity is articulated in cultural terms, whereby its members are said to share the same values and a common cultural heritage.To bring the people of Europe closer together and to deepen awareness of their "common" history, the European Union encourages all manner of meetings and exchange schemes between Europeans. Although its goal is to develop a feeling of belonging to a shared culture, the EU is also keen to preserve the specific aspects of Europe's many cultures.

Utgör deltagardemokrati ett hot eller komplement till den representativa demokratin? : En kvalitativ jämförande fallstudie av boenderådet i Hovsjö och ungdomsrådet i Västra-Skogås inom ramen för storstadssatsningen

The aim of this study is to investigate wether the participatory democracy is a threat or a complement to the representative democracy. To achieve my purpose I will focus on two different lokal councils, the civil council in Hovsjö and the youth council in Västra Skogås, which have been Objects of the urban policy in 1998. The theoretical framework on which this study is based consists of the participation democratic theory, representative democratic theory and implementation theory. By problemizing these theoretical frameworks in comparison with eachother I will mapp how these two lokal councils were implemented. The research question is: In what way was the civil council and the youth council a complement or threat to the representative democracy? In which way was it difficult to implement them?The method used for this purpose is a qualitative comparative case study.

Plask : ett gestaltningsförslag för en ny park i Västerås

The park at Djäkneberget and its surroundings is a beloved area in the city of Västerås. The area is one of the most popular sites for outdoor life and recreation of all sorts and it attracts different kind of people at different times during the day. The park includes a pond-system where protected species of frog and toad live and breed. These animals have been the Objects for many discussions concerning whether to explore the closeby areas or not. The prospected area is situated just next to one of the main ponds and consists of valuable foundationwalls were experts predict that the frogs and toads spend the winter. The municipality has now decided to restore this area to parkland. Because of the areas fascinating history I have chosen to do some research and give a short resume about it. For example are the existing park of Djäkneberget and its founder described together with a short description of the watersystem with the watertower that is situated in the area.

Går sociala risker att visa på en karta? Social rumslig riskanalys för Göteborgs stad

This essay deals with risk management and social risks, which have received increased attentionin recent years. Methods for dealing with social risks, for example within local Risk andvulnerability assessment (RSA), are currently under development. The purpose of this paper is toexamine if and how social risk can be quantitatively assessed and mapped using GeographicInformation Systems (GIS). The definition of social risk that the essay is based on states: "Theprobability of unwanted events, behaviors or conditions originating in the social conditions thathave a negative impact on the Objects that are worth to preserve.? A number of social riskindicators that can be used for a spatial analysis have been operationalized based on thisdefinition.

Elever i kommunala skolplaner : En diskursanalys av hur elever konstitueras som subjekt

The aim of this essay is to analyze how students are constituted as subjects in local curricula. The theoretical perspective is grounded in Michel Foucault?s notion of governmentality and power/knowledge and his critique of a sovereign subject. From this theoretical perspective I use Foucault?s concept of formation of Objects and Ernesto Laclau and Chantal Mouffe?s idea of subject positioning as tools for a discourse analysis.

Scenerier i glas - ett projekt om mönstermoduler

The present project was initiated with the aim to create pattern modules for use in public environments. My intention was to let the properties, of the specific materials used, have a marked influence on the realisation of the final form. I also wanted to find a material, which is suitable from the perspective of sustainabilityand possibilities to create modules from it. The work was initiated with a study of some candidate materials and many sketches before I finally made my choice. My decision was clear after a visit to the company Glasfabriken inKalmar.

Inte bara invandrare? : Diskursiva villkor för våldsutsatta tjejer i etniska minoritetsgrupper

A mapping process is ongoing in Sweden concerning a phenomenon known as ?honour related violence?. The explanations of ?honour related violence? often focus on culture and ethnicity, thus establishing differences between the majority society and offenders and victims. Given that some scholars critique mapping for focusing on predetermined Objects, my aim is to study discursive conditions for abused girls, who are constructed as being from within ethnic minorities, in relation to their contact with the Swedish welfare system.

Detection of interesting areas in images by using convexity and rotational symmetries

There are several methods avaliable to find areas of interest, but most fail at detecting such areas in cluttered scenes. In this paper two methods will be presented and tested in a qualitative perspective. The first is the darg operator, which is used to detect three dimensional convex or concave Objects by calculating the derivative of the argument of the gradient in one direction of four rotated versions. The four versions are thereafter added together in their original orientation. A multi scale version is recommended to avoid the problem that the standard deviation of the Gaussians, combined with the derivatives, controls the scale of the object, which is detected.
