Produktivitetseffekter av flerträdshantering
The main purpose of this study is to investigate the productivity effects of multiple tree handling in thinnings. Other important elements have been to investigate in which extent multi-tree handling is used in stands with different stem volumes and the impact of collecting partially delimbed fuelwood assortments has on harvesting performance.
The study is based on data from thinnings in Sydved and contractors' operating activities. Collection and compilation of operating schedules, number of stems and surveyed volumes from several contractors and a large number of executed orders underlying the results.
Multiple tree handling is used to a much greater extent at lower average stem volumes. Prediction models for productivity of the multiple-tree handling harvesters in the study differ from the productivity models for single-tree handling. In the model developed in this study productivity is not as dependent of stem volume as reference models.
Beståndsutveckling i stormskadade granbestånd
The storm Gudrun in 2005 led to massive windthow damage in forests in southern Sweden.
Since then there has been a growing interest in factors influencing wind damage in above all
Norway spruce (Picea Abies) stands. Although many other interesting areas still need to be
examined. In 2005 there where a lot of stands that suffered different degrees of damage, a lot of
these stands weren?t cut, but instead left to grow. The future development of these stands is
uncertain and the guidelines are unclear.
In-situ audiometri ? Vägen mot rätt förstärkning?
This study investigated whether in-situ audiometry, delivered via hearing aids, is a better option as a basis forprescribing hearing aid amplification, compared to conventional audiometry. By examining the real ear insertgain (REIG) in 29 ears (18 subjects), that had been fitted with a hearing aid programmed using both conventionalaudiometry and in-situ audiometry, the study looked at whether in-situ audiometry based prescription is closer tothe NAL NL1's fitting target than audiogram based prescription. The hearing aid Siemens Pure 7mi with speakerunit M was used on all participants. The results showed how in-situ audiometry based gain at certain frequenciesis more consistent with the target curve, especially at 1000, 1500, 2000 and 4000 Hz. It was not establishedwhether the findings of the study were statistically significant.
Spöa, sparka, slå och strypa: Kriminellas våldsattityder avslöjas med implicita mätningar
Attitudes towards violence were assessed using both implicit (The Single Category Implicit Association Test; Karpinski & Steinman, 2006) and explicit measurements (a Feeling Thermometer). A group of criminals showed more positive explicit and implicit attitudes towards violence than a group of non-criminals. In addition, The Aggression Questionnaire (Buss & Perry, 1992) revealed significant differences in aggression between the groups; criminals' mean scores were higher on all four subscales (physical aggression, verbal aggression, anger and hostility). Furthermore, significant correlations were found between all the measures, including the implicit and explicit attitude measures. The findings support the validity of the SC-IAT as an implicit measure of violent attitudes.
Nedläggningar och nyetableringar. En studie av hur folkbibliotekssituationen förändrats i Göteborg under 90-talet med hänsyn till stadsdelsnämndsreformen.
The purpose of this masters thesis is to examine the arguments that are being used when closing and establishing peoples libraries. During the 90:ies, in the community of Gothenburg, 4 public libraries were closed and another 3 public libraries were opened. A possible reason for this change lies in the reform from the city Committee that split the community of Gothenburg into 21 pieces; all with one centrally appointed political Committee. The library activity has since the reform was implemented got worse in some areas, foremost in the already neglected city sections, and better in some areas, which where able to establish new libraries. Argumentation analysis indicates that the arguments used at closure where mainly economical and neither the number nor relevance and validity of the arguments where good.
Den gemensamma utrikes och säkerhetspolitiken- Ett neo-funktionalistiskt perspektiv
This essay aims to explore the development of the common foreign and security policy within the European Union as well as the recent addition of the post of High representative in the field of the common foreign and security policy. This essay will attempt to achieve this trough exploring the questions; how have the aim of the European foreign policy developed, how the forms of cooperation has within this field developed and finally what impact will the recent addition of a high representative for the common foreign and security have. My aim is to answer these questions with the help of neo-functionalism.The results that came out of this essay point to the direction that the neo- functionalist premise about spill over effects and the notion about increased supranational influence turn out to have some validity in them. The study has shown that during the time the cooperation within the field of foreign and security policy have developed it is possible to see that supranational institutions will gain influence when the scope of integration within a policy area widens and deepens..
Natos intervention i Kosovo 1999 : En ställningstagande idéanalys av Natos argumentation om begreppet humanitära interventioner
This thesis is an analysis based on the problem of defining a humanitarian intervention and argues when or not, it is appropriate to operate it. The interest lies in finding out whether the argument itself is justifiable,not whether the act of interference was justifiable. My hypothesis is that both private and international operatios misuse the definition "humanitarian interventions" as an excuse to trespass the laws of war. Behind the idea of protecting human rights, freedom and democracy, is the liberalist idea of all individuals being equal. The respect for their freedom and rights drives outside actors to intervene when crimes are comitted against them.

Nationell identitet i konsten : Peter Johansson dekonstruerar mytbilden om svenskhet
The purpose of this examination is to identify how notions of Swedishness is created artistically, and from where these notions come. My method is to make a study on exhibition catalogues on the theme Swedishness/Nordism, with focus on the contemporary Swedish artist Peter Johansson. With a retrospect of his childhood in Dalecarlia, he investigates a Swedish iconography with it?s roots in national romanticism, which for more than one hundred years has been preserved and exploited of the tourist industry to market Sweden. It?s this monotonous iconography that Johansson deconstructs to make it appear like something else ? namely an iconography based on ethnic purity, which pushes away the foreign and protects the own.

Arbetsbelastning hos flygledare: utveckling av belastningsenkät för flygledningsarbete på mindre flygplatser.
In this thesis, it is investigated if it is possible to create a common factor of the work tasks done by an air traffic controller, which then can measure workload. This will lead to the development of a tool to measure workload at small airports. In the research project a questionnaire is created to measure the different tasks an air traffic controller has. The same questionnaire will also measure the number of environmental factors that exists around the air traffic controller. To measure the validity of the questionnaire, the authors are using NASA-TLX.
