Födoval hos juvenil piggvar (Psetta Maxima) : effekter av bytesstorlek

The effects of prey size on prey choice in different cohorts of juvenile turbot (Psetta maxima)were studied in three nursery areas at Gotland. Prey length measurements showed that gobies(Gobiidae) increased in average length during the season, while mysids (Mysidae) did not.Experiments on predation capacity of different size classes of turbot on different size classesof prey showed that juvenile turbot easily can eat gobies that are up to two thirds of their ownbody length, while the body size of turbot does not have any effect on the predation capacityon mysids. Stomach content of 217 turbots, less or equal 35 mm, was analysed to see if therewas any change in diet during the season, but there was no significant change in diet. Theoverall conclusion was that early settlers most likely have an advantage due to greater accessof alternative prey..

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.

Fo?rutsa?ttningar fo?r AU som sa?kerhetsgemenskap avseende inomstatliga konflikter med transnationell inblandning

The theory of ?security communities? is generally understood as ?dependable expectations of peaceful change? between groups and whether or not the African Union can be said to meet that criteria has been contested in the research community. One of the central disagreements lie in the nature of the region?s conflicts, of which a majority are intrastate but with tendencies of transnational involvement. This paper seeks to understand how extensive this involvement is and how it affects the possibility of classifying the African Union as a security community.

Tillgänglighetens frihet : En studie av Vägverkets måltolkning

In this paper I study how the repeal of the Swedish wealth tax (1 of January 2007) has affected people´s labour supply behaviour. This particular issue is relevant because it may help us understand some of the effects of the earnings tax changes that have taken place in Sweden. Accoring to standard economic theory a repealed wealth tax is similar to an income effect for the persons who previously paid the tax. That means that they theoretically will want to consume more leisure, that is decrease their labour supply. The method I am using to test this hypothesis is a difference-in-difference approach where the treatment group consists of persons who previously paid the tax and the control group of comparable persons who did not pay the tax.

Visualisering och beräkning av hudkapillärer

The aim of this thesis was to develop an objective and automatic method for identifying capillaries in microscope images of the skin. Furthermore, statistical data about the identified capillaries and the capillary distribution should be computed and stored in a database. The method was implemented using the platform independent programming language Java. An analysis of microscope improvement using various polarization filter setups and wavelength filtershas also been performed, as well as a pilot study of the effect of applying a local anaesthetic cream on the skin. The method is developed and aimed at research on various pathological skin conditions affecting the capillary distribution.

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.

Speloist

This thesis aims to examine the phenomenon of gambling and consequences that may result from having a gambling problem. The thesis also intends to investigate opportunities for support and a few explanatory- and treatment models. Games are taking on new shapes and access to gambling for money is on the rise. Studies on gambling have primarily been focusing on epidemiological factors rather than factors increasing or decreasing the risk of developing gambling-related problems. The empirical material is based on eight qualitative semi-structured interviews.

Lost in translation? En empirisk undersökning av användningen av tesaurer vid queryexpansion inom Cross Language Information Retrieval

The purpose of this thesis is to examine the performance of queries that is expanded before translation in comparison with only translation of the queries using a bilingual dictionary, and also to see if the number of terms that was used to expand the queries was of any importance i. e. if many terms from a thesaurus helped or destroyed a query. To answer these questions i used two online thesauri, Rogets thesaurus and Merriam-Webster Online and one printed bilingual dictionary, Norstedts English-Swedish dictionary. Even though the number of examined queries is too small to draw any definite conclusions, the results suggest that expanding using a general thesaurus may have a negative effect on the queries.

Uppföljning inom ett vårdvalssystem - En fallstudie av uppföljningen av husläkaruppdraget i Stockholms Läns Landsting

This study aims to examine the effect the evaluation system used by the Stockholm County Council, has on how the healthcare providers themselves conduct the evaluation regarding their own operations. This is done through a qualitative case study of the evaluation systems of the Stockholm County Council and of four primary healthcare producers concerning one primary healthcare contract. The evaluation systems were analysed using Merchant and Ver der Stede's (2007) framework for different types of control. In order to give a more detailed picture this framework was complemented with different types of performance measurement. The evaluation that the Stockholm County Council conducts was found to have little influence on the providers own evaluation with the exception of the quality indicators that are rewarded with a monetary bonus..

Individanpassat arbetssätt

Meeting the pupils at work it is important to endeavor an adjustment of the education with the purpose of developing the individual person. To make this possible it requires, except for the intentions of teaching with an individual adjustment, the teacher to make oneself acquainted with the schools work and liability. This is especially important in the work with students with difficulties. for this group of students perhaps an alternative form of education would be to prefer.As method of investigation I used a qualitative case study with a teacher who uses, what I would call, an alternative way of teaching. as a teacher you should pay attention to, and be aware of, how you effect your pupils and with this as a starting point conduct oneself.

Med kejsaren som referens : En studie om kejsarkultens påverkan på den skandinaviska aristokratins uppkomst och utveckling

During the three first centuries A.D the cult to roman emperor was practiced over the absolute majority of the known world. It was based on the idea of the deified ruler, where religion was used as a way of legitimizing a social position of an absolute few. It arrived from below but was promoted and spread from above as a way of governmental control. During the same period of time did a new aristocratic social group emerge in remote Scandinavia that eagerly sought new ways to identify themselves and their newly found social standing. With a base consisting of an economic surplus they wanted to create an acceptance for their new way of life and thus in doing so change the very foundation and core beliefs of their own society.The central theme of this study is the cultural exchange that took place between these two cultural spheres and mainly of the effect that the cult to the roman emperor had on the emergence and identification process of the Scandinavian aristocracy..

Knapphet och Selektivitet: Påverkan på attityd och värde

The study examines selectivity of the customer base and scarcity of a product?s effect on attitude and value towards a product or service. A questionnaire study is made from three different situations. The result varied depending on the situation; however it was found that selectivity of the customer base and scarcity has a great impact on the attitude and the perceived value towards a product or service. Selectivity of the customer base was found having the highest level of impact on both attitude and perceived value.

Modell av en synkronmaskin för PSCAD/EMTDC med magnetisk mättning i d-led och elektriskt gränssnitt för fältmatare

This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.

Skuldlättnader som vapen i kampen mot korruption? : Om hur HIPC-initiativet påverkar korruptionsgraden i berörda länder

This paper examines how debt cancellation, given under the HIPC-initiative, has affected corruption over the period 2000-2006. The examination is foremost interesting due to earlier research showing that high corruption leads to unequal distribution of economic resources. This, combined with the objective of the HIPC initiative to reduce poverty, indicates that combating corruption must be successful in order to fulfill the goals of the initiative. A linear regression shows that countries that have benefited from the HIPC-initiative indeed have a lower corruption than other countries. A panel-data analysis shows on the other hand that no effect on corruption due to debt cancellation or reforms undertaken in the program can be confirmed..
