Matrismodellen vs Two-part regressionsmodeller - effekter på Region Skånes resursfördelning
An important task for Region Skåne is to allocate resources to the health care districts. From 1999 to 2002 Region Skåne used needs-based resource allocation as a model for allocating resources. In a needs-based resource allocation individuals with the same socioeconomic and demographic characteristics are assumed to have the same level of need and are therefore allocated the same amount of resources. During the period of needs-based resource allocation a matrix model was used as a method. In the matrix model individuals were divided into cells after each combination of the socioeconomic and demographic variables.
International and national genetic evaluation of beef cattle : validation of national genetic evaluation models
After a workshop in Kuopio held in June 2006, Interbull decided to go forward with the development of a system for beef international genetic evaluation and a three year project called Interbeef was launched in June 2007. The participating countries are so far limited to Europe and the only trait evaluated at present is adjusted weaning weight (weight at 200 days). The results from a first international genetic evaluation have been shared with the countries but are not yet official. The evaluation is based on data from purebred Charolais and Limousin. To achieve good estimates of proofs in an international context it is important that methods for data validation and model selection are implemented.
Pricing Credit Default Index Swaptions A numerical evaluation of pricing models
This study examines the background and nature of the credit default index swaption (CDIS) and presentsrelevant methods for modelling credit risk. A CDIS is a credit derivative contract that gives the buyerright to enter into a credit default index swap (CDS index) contract at a given point in time. ACDS index, in turn, is a multi-name credit default swap (CDS). Within the eld of research, thisthesis identi es the CDIS pricing models presented by Jackson (2005), Rutkowski & Armstrong (2009)and Morini & Brigo (2011) as the most recognized and developed. These models are evaluated byreconstruction in a numerical software environment.
Politiskt förtryck: orsaksförklaringar, mekanismer och uttryck : Rohingyafolket som Agambens homo sacer i kontrast till Kymlickas liberaldemokratiska perspektiv
The persecution of the Rohingya Muslim minority population in southwestern Burma has come to the fore in recent years. The aim of this study is to first analyse the degree and respects of biopolitical control in the case of political oppression. Secondly, the aim is to compare the similarities and differences when it comes to the causes, mechanisms and expressions of the two theoretical starting points in the case.Giorgio Agamben´s biopolitical theory, which tries to reconnect state control over life and death with modernity, forms the basis of the analysis. Will Kymlicka´s liberal theory on minority rights serves as a theoretical comparison tool. Methodological starting points to the specific bilateral purpose will be both of the textual and discursive analytical tradition.
Att vara kvinna och styrelseproffs : En kvalitativ studie om kvinnor i svenska bolagsstyrelser
AbstractThe purpose of this thesis is to examine the professional female members of a board in listed companies. During the 21st century the issue of female quotation into the executive boards was discussed in both the media and politically due to womens underrepresentation in these contexts.The main purpose of this thesis is to examine the professional female members of boards stories of the role models they have, what characteristics have evolved, the views of others, and the self image. In addition, we want to investigate how women perceive themselves in a male-dominated field to identify how the female identity is created at work.Through a qualitative research in the form of personal interviews, we have gathered empirical material that forms the basis of our results. The answers from the interviews have been analyzed with the help of relevant theories and a social constructionist approach throughout the thesis. For our theoretical approach, we primarily chose symbolic interactionism, identity theories, and concepts such as the glass ceiling and gender strategies to analyze the data.The result of the survey shows that there are many elements that play into how women form their identities.
?Ett enormt resursslöseri? : En innehållslig idéanalys av debatten om förslaget att införa betyg från årskurs fyra
In the school political debate that is conducted in Sweden the question of grading is an ongoing topic of discussion. During the past year there has been a lively discussion about introducing grade from year four as suggested by the right wing parties. The purpose of this study is to set the teaching faculties? view and arguments in relation to the politicians' opinion in the ongoing debate about the proposal of introducing grades from year four. Furthermore, the aim is to investigate how central the didactic arguments are in relation to other arguments in the current debate.
Barns religionsfrihet i förskolan : En kvalitativ intervjustudie
AbstractMany opinions are divided on what religious freedom should protect and the area is unexploredin preschool. Is it the parents, the child or preschool teacher right? The aim of the studywas to investigate Maria klasson Sundin´s concept and Theoretical models of religious freedomfor children through three Swedish preschool settings and also how three teachers interpretsand expresses children's freedom of religion. Through a qualitative interview study theaim was to investigate how the concepts of religion, autonomy and freedom is interpreted andexpressed by the teachers so a picture through this three concepts can categorise the teachersin a model; freedom of thought, tradition and life interpretation model so a broader picturecan be made to understand how the children's freedom of religion is expressed in the preschoolsetting and how the teachers work. The Result showed through the analysis that themodels fail to categorise the teachers in any theoretical model but on the other hand the understandingof preschool teacher?s expression and interpretation of the concept of religion,autonomy and freedom showed both diversity and lack of knowledge on the subject mattersreligious freedom which fall within the child rights issues.
Däck-mark Interaktion hos skogsmaskiner
The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.
Bokbussen kommer och går ? men består? En undersökning av hur bokbussverksamhet skildrats i Biblioteksbladet 1945-2006
The aim of this master?s thesis is to investigate a possible connection between the development of mobile library services in Sweden and the development of cultural policy during 1945-2006. Our main question is: is there a connection between the development of the mobile library services in Sweden, as described in Biblioteksbladet, and the development of cultural policy as portrayed by Anders Frenander and Dorte Skot-Hansen? In order to answer this question, we formulated two secondary questions: - How are the mobile library services described in Biblioteksbladet between 1945 and 2006? - Are there any similarities or dissimilarities between the development of the mobile library services and the development cultural policy as described in our Theoretical models? If so, in what way? Our study covers the entire time period since the start of the mobile library services in Sweden in the late 1940s. The final year for our investigation is 2006.

This report is part of a Bachelor?s degree corresponding to 15 creditsat the Royal Institute of Technology, Stockholm. The work hasbeen carried out by Max Wikander, author of the report, supervisedby Lanie Gutierrez-Farewik and Erik Dijkstra.Gait analysis includes measurement, characterization and assessmentof human movement and is used to assess kinematic or otherabnormalities during gait. Center of rotation and the axis of rotationof a joint are fundamental parameters in motion analysis. However,the ability to create individualized analysis is limited by the lack ofaccuracy when these parameters are calculated.

The result were two models. The first model were one minor part of the whole design in 2D, to be able to optimize and study the minor part with a faster loss simulation. The second model was the whole design in 3D. The whole model were done with the three programs Solidworks, Comsol and Matlab.
Rekursiv greyboxidentifiering av drivsystem i industrirobot.
In modern industrial robots the components in the transmission contain nonlinearities. These nonlinearities need to be to estimated either for better control or to use the parameters for diagnosis of the system. There is a lot of work done within system identification and mainly within the field of iterative parameter estimation.This thesis considers recursive grey-box identification for a nonlinear model of the transmission in an industrial robot. The nonlinearities that are identified are friction, spring stiffnes, hysteresis and backlash. These nonlinearities are a part of the models that are presented in this thesis.
Prognostisering av räntabilitet på eget kapital - En jämförelsestudie av tre regressionsmodellers prognosförmåga applicerat på svenska data
A multivariate cross-sectional model is used in this thesis to proxy for expected earnings and to estimate return on equity for 214 companies over the period 2009-2013, using Swedish data. The model, which has never been tested on Swedish data before, is first confirmed to function as a forecasting model for expected return. Furthermore, the model is evaluated through a comparison with two univariate models based on the assumption that return on equity follows a mean reversion process. Forecast accuracy is calculated as the difference of estimated returns and actual returns. The results show that the univariate models' forecasts are superior to the multivariate model's..
