Det maskerande brusljudets påverkan på inlärningen av visuell information : om effekten av maskerande brusljud i öppna kontorslandskap

Denna experimentella studie undersökte om maskerande brusljud på ovidkommande tal påverkar inlärning av visuell information. Experimentet genomfördes i ett laboratorium med 32 försöksdeltagare. Visuella ord presenterades för försöksdeltagarna samtidigt som auditivt tal från samma semantiska kategori, med eller utan maskerande brusljud, presenterades. De visuella orden skulle återges i valfri ordning. Resultatet av studien visar att ett maskerande brusljud på ovidkommande tal har positiv effekt på inlärningsförmågan.

Försäkringskassans roll i den arbetslivsinriktade rehabiliteringen : Ett handläggarperspektiv

The purpose of this essay was to describe and analyse the tension/conflict between external demands and actual conditions, as experienced (and told in interviews) by employees at two social insurance offices in Scania, concerning their roles in the process of working life rehabilitation. The theoretical starting point is the theory of street-level bureaucrats, as defined by Lipsky. The comprehension among the employees were that working life rehabilitation services are approved less today compared to a few years ago. The discretion, i.e. the position to choose among competing alternatives; about what to do, how to do it etc., characteristic of street-level bureaucrats, according to the employees is less prominent, as the routines of handling cases and decision making are regulated.

Tjänstekvalitet för pensionssparande : En studie om vilka faktorer som påverkar den upplevda tjänstekvaliteten för pensionssparande

Our purpose of this paper is to seek an understanding of which service quality factors that affects customers in their decision making progress regarding purchasing financial services such as pension products. We also seek to evaluate the different service quality factors by compare their relative strength against each other. The study aim to investigate if there are any connections between customer behavior variables such as gender, age and income in comparison to these service quality factors related to pension products.The findings aim to help a small financial institute such as our case company Plain Capital to understand how their customers experience service quality regarding pension products.In order to find empirical results we conducted a qualitative research as well a quantitative research. The qualitative research employed both a focus group interview with pension savers and an interview with our case company Plain Capital. We were able to identify the service quality factors for pension?s products with help from the focus group interview.

Att skriva utan penna : En studie av datorns betydelse för skrivande på gymnasienivå

The purpose of this study is to investigate how important computers are for text production in upper secondary school level, and to find out what attitudes some students have towards computers in writing classes. I have let 44 students in the Swedish gymnasium course Swedish B write an argumentative essay. Half of the group wrote using paper and pencil, and the other half used computers. The essays were graded, and the language and length of the texts were analyzed. The students also filled in a questionnaire with questions on computer aided writing classes.The results showed that the texts that were written with computers contained a significant larger amount of words and fewer spelling mistakes.

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.

Rekonstruktörens skadeståndsansvar

The thesis consists in two parts. The purpose of the first part is to analyse how the court may interpret rules, principles and legal cases to decide whether a reconstructor bears liability towards the debtor and the creditors. In the second part it is discussed and argued for how the reconstructor´s damage liability should be drawn up and applied so that it according to economic theories should be as efficient as possible. In the thesis it is shown that it is not a non-contractual liability or a liability based on authority mission. The reconstructor´s liability is instead based on a commission concerning an intellectual service.

The development in electronics increases the demand for good design methods and design tools in the field of electrical engeneering. To improve their design methods Ericsson Microwave Systems AB is interested in using computer tools to create a link between the specification and the implementation of a digital system in a FPGA. Xilinx System Generator for DSP is a tool for implementing a model of a digital signalprocessing algorithm in a Xilinx FPGA. To evaluate Xilinx System Generator two testcases has been designed. The testcases are selected to represent the FPGA designs made at Ericsson Microwave Systems.

Hälsa och hälsorelaterat beteende : En undersökning av beteendets betydelse för den självskattade allmänna hälsan

An increasing number of health problems in the population and an uneven distribution of health between different groups in the society, have been identified as a problems and has therefore been put on the political agenda in Sweden. Thus, the purpose of this thesis is to estimate and discuss the significance an individual?s behaviour, in a number of areas, has on his/her level of health.The empirical material for this thesis is taken from a nationwide inquiry conducted in 2004,which was called ?Hälsa på lika villkor?? (Health on equal terms?) The material used consists of the answers and records from individuals living in the administrative district of Kronoberg. 9972 individuals were included in the sample and the answering frequency was 63,2%. To map and analyse the material, which was done mainly through crosstabs, chi-square tests and logistic regressions, the statistics software SPSS 11.5 was used.The parameter used to measure the health level is the individual?s own perception of his or her general health.

Testbänk för motorbåtsdrev

Marinediesel has, to meet there customers needs for a suitable sterndrive to powerboats, developed a prototype. The prototype is currently in the testing phase. The opportunity to test the sterndrive under load inside the workshop has not previously been possible. Until now the drive has been tested in a test bench without any load on the propeller axle. The prototype has also been tested under real conditions mounted on a boat.The idea with my thesis was to create a test bench that can run around the clock in order to be able to test things like wear and service intervals and other things that require that the test interval is long.

Kartläggning av intensivvårdspatienters sömn och faktorer som kan påverka sömn

Sleep has a recreating, health promotive and regenerative function. Research shows that intensive care patients suffer from sleep deprivation and bad sleep quality with considerable negative consequences.The aim of the report was to examine how much nocturnal sleep patients without ventilator treatment get and to observe factors that may influence sleep.Methods: An observation chart was used to collect data. The staff?s observation of the patients? night sleep and estimated nocturnal noise- and light levels in the patients? rooms were documented. The patients? answers to questions about pain and possible causes for their awakenings were noted.

Studie om individers kontrastkänslighet och preferenser för horisontell och vertikal belysningsstyrka

The purpose of this study is to survey and evaluate if the individual contrast sensitivity and preferences for horizontal and vertical lighting level correspond to the values that standard SS-EN 12464-1 recommends for the workplace- and surrounding light levels.This study examines if lighting should be adapted after the individuals? need or if a general value can be found that will cover every individuals? need for a workplace and surrounding light level. This study also examines if parameters like sex, age and/or glasses/lenses have an effect on the amount of lighting that the test subjects need. Lastly we compared the values concerning the relationship between workplace- and surrounding light levels with standard SS-EN 12464-1?s recommendations.The study is carried out with an experimental design that surveys 220 test subjects who were chosen by a selection of convenience.

The change of haemoglobin during blood donation, and an assessment of a photometrical method for non-invasive haemoglobin analysis

In Sweden, lowest acceptable haemoglobin levels in blood donators are 125g/L for women and 135g/L for men for a test sample taken in the beginning of the blood donation. Levels, which are 10g/L lower, are accepted if the sample is taken after the blood donation. Earlier studies show that the haemoglobin level decreases for a person that is lying down.The two aims of this study were to examine how much the haemoglobin levels change during blood donation and to examine if the photometrical instrument Pronto-7TM shows equivalent results to that of the established method Cell-Dyn Sapphire.In the study, 120 blood donors participated. Blood samples were taken in the beginning and in the end of the donation. Analyses by Pronto-7TM were done before and after the donation.The haemoglobin level decreased significantly during the blood donation.

Grammatiken bakom den politiska retoriken : En syntaxstudie av före detta statssekreterare Lars Danielssons uttalanden angående sitt ansvar i regeringens hantering av tsunamikatastrofen 2004

In this thesis I based on Fowler?s method of syntax analysis construct a flow scheme which I then use to make a syntax analysis of former State Secretary Lars Danielsson?s statements, in his autobiography, regarding his responsibility in the Swedish government?s management of the 2004 Indian Ocean tsunami disaster. The focus of the flow scheme is how grammatical constructions can be used in the interest of rhetoric?s to on the syntax (non-explicit) level of the text indicate and place responsibility with or outside of involved individuals. The main conclusion of the syntax analysis performed is that Danielsson in his autobiography in fact does not use very many of the constructions described in the flow scheme, whereby it can be concluded that the syntax analysis in this case wasn?t so ?revealing?.

Analys, design och konstruktion av en ITS-prototyp : Att övervaka och informera transporter av farligt gods på väg

The Swine flu (H1N1) erupted in 2009 and wasquickly spread over the world and developed into a pandemic, with a great threat against people?s health. It was soon discovered that the H1N1?virus had a different character than the seasonal flu, since it especially affected younger individuals and the consequences from the disease were expected to be more severe. In Sweden it was decided to provide a free of charge vaccination against the H1N1-virus, and the Swedish vaccination ratiobecome relatively high compared to other countries.
