Navigationshjälpmedel i tredimensionella virtuella miljöer och understödjande av minne
This thesis explores different ways of navigation in virtual environments. It also investigates how virtual environments can support human memory. Tests are done using a self made virtual model of Orkanen Library, Malmö högskolas school library. Among the different navigation tests that were done, a visual guidance in form of a line on the ground leading to the goal is showed superior when navigating a virtual environment but that people prefer legible landmarks instead. Tests were also done which show that a 3D-model of a real location supports context based memory.
Det svenska konsumtionsbeteendet-En ekonometrisk analys av den permanenta inkomsthypotesen
Abstract Titel: Det svenska konsumtionsbeteendet ? En ekonometrisk analys av den permanenta inkomsthypotesenTopic/course: NEKK01, Bachelor thesisWriters: Ida Hedlund, Anna Persdotter Supervisor: Fredrik NG Andersson Keywords: Permanent income hypothesis, Milton Friedman, Consumption smoothing, Sweden Purpose: The purpose of this thesis is to examine whether the permanent income hypothesis can be applied on the consumption pattern of Sweden during the time period 1950-2006. Method: To do the observation an econometric regression analysis has been made. The variables tested are consumption, real GDP, stock- and real estate market prices. In the model three different time periods have been investigated to facilitate the origin of different patterns.
Kommunal självstyrelse - en myt? : En lokalhistorisk studie av Borgviks kommun 1861-1924
The hypothesis of this study is that the local government act in Sweden 1862 was an instrument for the state to keep its´ political influence on the local level. It did not open for local self-government. The swedish historians Dahlkvist and Strandberg description of the Swedish local government act support this hypothesis, as does the analysis of political scientists Pettersson and Söderlind. The general opinion that the local government act opened for local self-government does still exist among many swedish historians.This study had two aims. The first was to investigate the actual extent of self-government in Borgvik, a small municipality in Sweden during the period 1861-1924.
Nationella prov i NO : Verktyg för likvärdig bedömning eller dolda svenskaprov som diskriminerar?
This study is focusing on students at compulsory level and their performance in national exam tests when the students first language is taken into account. Students in Swedish schools with non-Swedish speaking parents commonly follow language classes for limited Swedish proficient students. How does this affect their results when tested in other subjects as physics,biology and chemistry? A general claim is that national tests can provide data for balancedand fair grades. This view is challenged in this paper, through Principal Component Analysisof test results that shows a difference between schools when the schools social position and share of limited Swedish proficient students are measured.
A review of methods used to measuretemperamental characteristics in horses
Horses respond individually to challenges, and the possibility to use these reactions to evaluate equine temperament with an objective instrument would have several advantages. Horse welfare could be improved by making it possible to find individuals best suited for a specific use, and understanding of the development of abnormal behaviours, such as stereotypies, could be increased. Management routines and training could be adjusted tosuit each individual horse and it could facilitate the selection of individuals appropriate for breeding. There are also economic implications, as horse buyers consider temperament important and after evaluating temperament, money can be spent solely on specific horses with all the right qualities. During the last decade, many attempts have been made to measure different aspects of temperament in horses, and the first aim of this project was to look at these studies and see which methods were used and which temperamental characteristics they measured.
Reklamprat: effekter på upplevt reklamvärde och köpintention
This thesis provides the first test of the effects of ?advertising talk?, i.e. comments, discussions and opinions about advertising. Despite its prevalence quantitative research on advertising talk has been scarce and this study is thus an attempt to fill in some blanks. Hypothesizing that advertising talk will enhance consumer-perceived advertising value as well as purchase intentions and that the effects are more pronounced for talk generated by consumers as compared to marketers, I use a fictional campaign to measure responses in an experimental study.

Kommunikation i operationsmiljö : en litteraturöversikt
AbstractAim: The aim of this study was to investigate if treatment with ?dry needling? in myofascial triggerpoints (MTrPs) in the rotatorcuff muscles may affect impingement symptoms such as pain during provocative tests, shoulder mobility, and function. The research questions were: Does the value of pain change on the Visual Analog Pain Scale (VAS) between before and after treatment? Do the positive provocative tests for impingement change between before and after treatment? Does the active shoulder mobility change between before and after treatment? Does the self-rated function change between before and after treatment?Method: The study was a prospective randomized intervention study and 19 persons with impingement symptoms (mean ± standard deviation; 58 ± 18 years, and shoulder pain duration 3.9 ± 1.6 months) were randomized into two groups. The groups were tested before, directly after and 3 weeks after treatment.
En studie av lösensdagseffekt på aktiekursens volatilitet
The purpose of this study is to examine the expiration day effect on a stocks volatility due to stock option expiration, which is every third Friday in the month on Stockholm stock exchange. Volatility is the standard deviation of a stock. It measures the uncertainty about a stocks future movement. When volatility increases, the chance or probability of a stock going up or down increases. It?s a common rumor among stock traders that stock volatility tends to increase nearby expiration day.
Kartläggning av hörselnedsättningar, öronsjukdomar samt diagnostiseringsmöjligheter hos 1 ? 5 åriga barn
Ear disease and hearing loss in preschool children can be difficult to discover and diagnose. This paper investigates ear disease in 20 children controls from 1 to 5 years of age. The aim of the study was to map prevalence and incidence for ear disease, and prevalence of hearing loss in a group of children.Twenty children wide aged 1, 1½, 3 and 5 were included and investigated according to a set protocol with psychoacoustic tests, tympanometry, ear microscopy and a parental questionnaire. The majority of the children could be evaluated by age adequate psychoacoustic tests and otoscopy. Tympanometry was the investigation method that was most difficult to perform.

Hur hanterar institutioner en miljö med blandade Operativsystem?
The purpose of this thesis is to investigate if there are environments that use
some kind of central authentication system within institutions/schools. The
hypothesis is that an institution not using a form of central authentication
service has more need for maintenance and as such is considered a higher cost
for the organization.
The gathering of data has been done through interviews with technical personal
at Blekinge Tekniska Högskola and Linköpings Universitet. Based on the
technical background of the authors, and the system limited to discussing
Windows and UNIX operating systems, a discussion and analysis of the systems
working today has been done, with emphasize on the hypothesis..
Virkets formförändring och dess betydelse vid postning :
The purpose of this thesis was to create a saw pattern program for the sawmill industry. I have chosen to focus on the module that describes the shrinking on the wood. There are several theories about how the wood deforms by shrinking. Several hypotheses were simulated in the program and after testing them I decided to use only one of them (hypothesis C).
The program is written in Visual Basic .NET and I choused that program language because it
is easy to do changes in the layout. Another great advantage in Visual .Net is that you can mix different languages in the same program.

Responsive web design : En studie i hur designkonceptet påverkar användbarheten hos en webbplats
The main topic of this thesis is to evaluate the impact on the usability of web pages when using responsive web design, a concept for developing web pages whose design adapts to the screen size being used. This is done by creating a responsive prototype based on an existing web site. A number of usability tests are conducted on the two versions of the site in order to compare the time to complete the tests and to observe the behaviour of the test participants. The tests are conducted on desktop as well as on mobile devices with varying screen size.The number of test participants was relatively low, and so the quantitative result is not statistically valid. However, the conclusion is that the most effective combination is to use either of the sites on desktop format.
