Humorstilar, Emotionell Perception och Kön ? Vem skrattar mest och vem skrattar sist?
The main aim of this research was to investigate four humour styles, affiliative, self-enhancing, aggressive, and self-defeating humour, and compare these with emotional perception. Forty-eight persons took part in the research, 27 women and 21 men living in the southern part of Sweden. Two humour tests were used: the Humour Scale Questionnaire ? HSQ, with 32 items, and a newly composed video test, assembled after pilot testing from 26 video clips, the Humour Video Questionnaire ? HVQ. To measure perception and interpretation of emotion, the revised version of the ?Reading the Mind in the Eyes? Test was used.
Är Marknaden Varse om Varsel? : En studie om den svenska kapitalmarknadens reaktion på varsel om uppsägning

The method of this study has been interviews with principals, teachers and pupils to get as many perspectives of the subject as possible. It has contributed to an interesting content and the end result will be as fundamental as it can be. The findings of this study show that teachers teaching English in Sweden have a great responsibility because of the lack of subject priority and communication between themselves, the government and other authorities in the world of education.
CMS och UX : tekniker för hur man utformar en god användarupplevelse
The purpouse of this study is to find out how and if a Content Managment System (CMS) can benefit from applied User Experience Design (UX). A work project has been executed where a client wanted the students to create a user friendly CMS for adding content to a global hotel review site. A prototype of a CMS was created based on literature studies about UX and CMS. The prototype of the user friendly CMS was then tested through user tests and interviews with key users. After input from the key users the prototype was changed until the users were satisfied with it..
En komparativ litteraturstudie av olika termkällor för query expansion
The purpose of this thesis is to make a comparative literary study of ten laboratory experiments with different kind of sources for query expansion terms. The experiments are grouped according to categories of term sources, which are: search results, collection dependent knowledge structures, collection independent knowledge structures and one that combines the two last mentioned sources into one. To enable a comparison all other variables were held as constant as possible. There is the improvement measured in mean average precision, which is used to measure the various sources potential. The result from the study shows a strong connection between the kind of source for the expansion term and improvement of the result.
Beslutsfattande och uppmärksamhet : Heuristikers påverkan på kognitiva resurser inom konsumentpsykologi
Every day we make numerous decisions. Some are better than others. Intuitive decisions usually results in less good decisions when we do not reason about our choices. Research has been interested about the process that is behind how we make good decisions. Decisions we face every day, such as when we shop, determined using various mental shortcuts that we use unconsciously.
Luftutsläpp från järnmalmsproduktion : - Strategier för systematisk luftkvalitetsmätning
The mining company LKAB extracts iron ore in three areas in the north of Sweden, Kiruna, Malmberget and Svappavaara. The iron ore is refined and in the pelletizing plants the material is rolled to finished pellet product. The different steps of pelletizing plants causes among other things emissions to the air. It occurs occasionally stops in the production and the emissions are vented via an emergency chimney without purification. The aim for this work is to look into how LKAB may improve their monitoring of air emissions and control of ambient air quality and the analysis methods which are suitable for measuring.
Före och efter Trappan-modellen : En pilotstudie om psykiska, emotionella och beteendemässiga förändringar hos barn som upplevt pappas våld mot mamma
The Trappan Model is one of the most implemented treatment programs for children who have experienced domestic violence. This study undertakes a wider evaluation of the model through a pilot study. The approach is both quantitive and qualitative. Theory as well as the Strengths and Difficulties Questionnaire have been used to fulfil the aim. The design is pre-post.
Metodundersökning av tre metoder för kvävemätning i en arktisk äng : Jämförelse mellan mätmetoderna extraktion, inkubation och jonbytesmembran (PRS-sond)
The purpose with this report was to compare three commonly occurring methods for measuring plant available nitrogen in soils. The methods extraction, incubation and Plant root simulator (PRS) probe - an ion exchange membrane (Western Ag Innovations, Inc., Saskatoon, Canada) method were used and comparison between these methods were conducted. A full factorial experiment were set up in northern Finland with the treatments excluding herbivores, warming and fertilization to see how the inorganic nitrogen content in the soil was effected by the treatments. Soil cores were taken and from them a subsample was incubated for 18 days and thereafter analyzed for inorganic N in laboratory. PRS- probes were in the ground for 1 month.
Naturliga filtermaterial för reduktion av metaller i dagvatten
Förorenat dagvatten från Stena Gotthards metallåtervinningsanläggning i Eskilstuna har filtrerats genom kolonner innehållande två olika adsorbenter, torv och furubarksflis. Torv är en organisk jordart som främst används som bränsle och furubarksflis är en biprodukt från skogsindustrin. Båda filtermaterialen är relativt billiga och finns i stora kvantiteter i Sverige. Filtermaterialen har visat sig ha varierande kapacitet att adsorbera metaller i vatten på grund av själva materialet samt vattnets sammansättning. Resultatet från den här studien visar att av de två undersökta filtermaterialen så har furubarksflis störst kapacitet att reducera bly, koppar och zink från det specifika dag vattnet..
En flashestimator för den privata konsumtionen i Sverige med hjälpvariablerna HIP och detaljhandeln ? En tidsserieanalys med hjälp av statistikprogrammet TRAMO
In this essay we aim at finding an appropriate flash estimator of the quarterly Swedish private consumption (PK). With the aid of the statistics program TRAMO we study if monthly data from the consumer survey (HIP) and retail industry (DH) can be used in a transfer function model (TFM) to forecast PK. In the work of assessing the state of the market and the business trend, fast information from the national accounts is needed for making decisions for the economic politics in Sweden. A way to speed up the information process is to use leading economic indicators to asses this development. Another way to get information faster is to use a flash estimate.
OSE och Linux : En studie om prestanda
There are some key elements which distinguish a general operating system, such as Linux, from a Real Time operating system, such as OSE. The later belongs to the category of soft Real Time systems while Linux is a general operating system, with significantly improved real time properties after version 2.6. These improvements make it interesting to compare the two systems.When comparing two operating systems, there are a number of issues which have to be considered. One way to measure the performance of the systems is by studying the time consumption for the same functionality and hardware.During the study, the items that appeared as the most important for the performance of the systems, were: process primitives, system primitives, interprocess communication, context switches and interrupt latency.This work demonstrates that it is possible and reasonable to do performance testing on two different operating systems. The implemented tests cover a number of basic functionalities, which appeared to be the most crucial ones for the performance of the systems..
Utvärdering av den nationella söktjänsten LIBRIS
LIBRIS is a national library search engine offering information about 6 million books, articles, dissertations and other materials held by Swedish university libraries, research libraries and public libraries. In December 2007 a new version of LIBRIS was launched, developed with focus on usability, simplicity and accessibility. This thesis examines how the new LIBRIS is used, what is working well and what could be improved and also what the users think of LIBRIS. The following report is based partly on a study of usability and partly on a series of tests where librarians, scientists, students and developers have executed a number of tasks while thinking aloud. The users also participated in an interview.
På spaning efter kreativiteten och dess självbild... En studie av unga kvinnor
The aim of this study was to examine creativity, measured with four different tests, and self-image in 18-19 year old women (N = 30), and their earlier presence of imaginary companions. The result showed that there were many correlations between the different creativity measurements. Self-image correlated significant with fluency of ideas in one test. "Psychological health" along with "skills, talent and abilities" were the two most important self-image aspects for creativity. We found negative relationships between imaginary companions and creativity, but a positive relationship with self-image.
