A1210Teknisk aktieanalys används för att från historiska kursdata försöka förutsäga den framtida kursutvecklingen. Uppsatsens syfte är att undersöka börstrendens inverkan av resultaten för två olika tekniska analysmodeller, glidande medelvärde och Relative Strength Index (RSI). Som dataunderlag används 12 aktier från Stockholmsbörsens A-lista för Mest omsatta aktier mellan 1988-03-01 och 2004-03-01.I studien tillämpas blankning för att oberoende av den rådande trenden ha möjlighet att generera överavkastning. Överavkastningen undersöks genom att riskjustera avkastningen med Capital Asset Pricing Model (CAPM). Vidare belastas varje transaktion med en courtageavgift.Det visar sig att endast köpsignalerna är statistiskt signifikanta.

A school is a social area in which children and adults meet each other. The school is were friendship, love and also enmity arise. The process to establish, maintain, split up and end relationships is constantly continuously. A Childs way of creating relationships is complex. Bullying and similar offending treatment occur and has always been a huge problem in school.

Bakgrund: Effektiva marknadshypotesen innebär att det inte går att utnyttja systematiska avvikelser på marknaden. Trots det finns det etablerade investeringsstrategier som investerare använder sig av för att generera överavkastning.Syfte: Syftet med studien är att undersöka huruvida det går att generar överavkastning genom att investera i företag som uppvisar en låg eller hög EV/EBITDA-multipel. Variablerna bransch och risk kommer även att undersökas med utgångspunkt från den eventuella förekomsten av en investeringsstrategi som genererar överavkastning.Genomförande: Teori inom området har byggt upp en grundförståelse för problemet, empiri har sedan hämtats från de olika företagen för att få fram EV/EBITDA-multiplar till de ingående portföljerna i studien. Aktiekurser har även inhämtats för att bygga grunden till empirin. Resultatet har sedan jämförts med OMXSPI samt med den riskjusterade avkastningen.Resultat: Av resultatet framkommer att det går att utnyttja en investeringsstrategi där investering görs i låga EV/EBITDA-multiplar.

Bakgrund: Ungefär 100 000 människor i Sverige beräknas lida av Alzheimers sjukdom. Vanliga symtom är minnesförlust och nedsatt inlärningsförmåga. Vården av de med Alzheimers sjukdom sker ofta i hemmet av en närstående. Dessa närstående får inte tillräckligt med information och deras livskvalitet blir sämre. Det är därför viktigt att vårdpersonalen kar kunskap om de upplevelser som de närstående vårdarna har för att kunna stötta dem.

The purpose of this study was to examine how professional workers understand the bullying problem among Swedish youth in the age of 13-15 years. The main focus was to examine the new phenomena electronic bullying, from a professional point of view.The biggest question to answer was: "How does the school and organizations understand the bullying situation among Swedish youth today?" Individual interviews with professional social workers within the school and nationwide organizations have been used to fulfill the purpose of this work. Two different respondent types were used in order to get a wide perspective and a dynamic view.Electronic bullying had increased, but the school yard was still the most common arena for bullying, according to the respondents. The schools tried to prevent bullying, but the social workers felt that they lacked some knowledge of electronic bullying, because it was relative new.

With an increased empowerment of the users, and a dependence on outside critics, one wonders what kind of role the librarians have in a context where qualitative literature is discussed. The aim of this study is to examine the relationship between librarians private and professional views on qualitative fiction, in order to be able to discuss their role as quality intermediaries in a user oriented context.The method used, is the qualitative, semistructured interview. This author interviewed seven librarians from three different libraries in Sweden. The theoretical emphasis partly relies on the ten words of qualitative value that Inger Elam and Bengt Brülde discusses in their respective texts, partly on David Garvins quality assessment theory, which defines several quality categories divided between an absolute and a relative quality view.Through the comparison between the private and the professional quality view, examined with the two theoretical approaches, the analysis of the interview material shows that there lies a complexity in the librarians professional role. On the one hand, they are dependent of both the users and the critics judgements about the qualitative aspect in the work with purchasing new literature to the library.

Vehicle simulators are becoming more common in vehicle industries. Company earns lot of money on simulations instead of real tests. Real tests are necessary but not made so extensively as before.In this thesis the building of an vehice simulator will be described and a comparison between three different cruise controls. The three cruise controls are PI-regulator, a regulator who regulates after positions in the terrain and a MPC-regulator. The reason for choosing this three is to see the difference between simple regulation and more complex regulation with respect to fuel consumption, travel time and complexity.The vehicle simulator is made in Matlab/Simulink, Visual Studio and Open Scene Graph.

Bakgrund: En psykossjukdom är en sjukdom som inte bara drabbar personen själv utan hela dennes familj. Hela familjens livsvärld påverkas och familjelivet ansträngs hårt. Den psykossjuka familjemedlemmen erfar världen på ett annorlunda sätt. Vanliga symtom vid en psykos är bland annat hallucinationer och vanföreställningar. En bra vårdrelation mellan vårdgivare, den sjuka psykossjuka familjemedlemmen och anhöriga är en förutsättning för återhämtning.Syfte: Få ökad kunskap om och förståelse för anhörigas upplevelse av att leva med en familjemedlem med psykossjukdom.Metod: Metoden som valdes för studien var en systematisk litteraturstudie i vilken elva vetenskapliga artiklar analyserades med en kvalitativ innehållsanalys.Resultat: Tre kategorier framträdde ur data.

Cycling is one of the most sustainable transport modes available and it is widely promoted inmany urban areas. The health benefits from cycling has shown to be substantial, includingdecreased risks of diseases related to overweight and enhancing brain capacity. However, inurban areas cyclists can temporaly be exposed to high levels of air pollution, resulting inhealth risks as opposed to health benefits.The objective of this thesis is to develop a rasterbased test model in GIS that estimates theinhaled dose of air pollution for cyclists based on relative particle concentration in differenttransportation micro-environments. The method used is a least-cost path approach,calculating three different routes; shortest, fastest and least dose for four different trips withinSödermalm, Stockholm.The results show that the inhaled particle dose can be greatly reduced, 39% - 58% for three ofthe routes, by choosing the least dose route. One of the most interesting findings is thesubstantial increase of dose when high levels of particles are combined with uphill cycling.The conclusion for the thesis is that a raster-GIS model can be very useful for estimating doseof different air pollution particles and chemicals along cycling routes.

Anhöriga till svårt sjuka patienter kan uppleva känslor som rädsla, ensamhet, hjälplöshet samt osäkerhet. Syfte: Syftet var att beskriva mötet och interaktionen mellan sjuksköterskan och anhöriga till svårt sjuka patienter. Metod: Studien är en allmän litteraturstudie baserad på kvalitativ och kvantitativ forskning.

The aim of this thesis is to compare the effectivity of using a natural language and a controlled vocabulary when performing subject searches in the bibliographic database LISA Library and Information Science Abstracts. 20 topics were created and for each topic two searches were made, one by using a query formulated with natural language directed to the abstract field and the other one by using a query formulated with descriptors from the thesaurus in LISA directed to the descriptor field. The average relative recall amounted to 64,8% for the AB-queries and 54% for the DE-queries. Failure analysis showed that the majority of the relevant documents not retrieved by AB-queries could have been retrieved with other query terms, such as synonyms. In a natural language there are many different ways of expressing a topic, and this tends to have a negative effect on retrieval effectivity.

This study is about care managers, who process in the care of the elderly, regarding to needs, rules, regulations, guidelines and their freedom of space. The purpose with this study is to understand how the care managers process out of the basis from the needs of the elderly, the municipal guidelines in relation to the caremanagers freedom of space.The study has a qualitative approach and is based on semistructured interviews with five different care managers.To analyze our interview material we have use the street-level bureaucrat theory by Lipsky and Johansson and the theoretical idea empowerment. Before we started our research about care managers we had an understanding in that the organization had an influence in the judgment of the needs of the elderly. Now we have an understanding in that the relative to the elderly is the one who wants to affect the care manager during the judgment of needs in what effort to make. Our study indicates that it exist insecurity regarding to the municipal guidelines, which was surprising. We thought that the guideline was something positive and a help full tool for the care managers.The result in our research points out that the guidelines makes insecurity instead of comfort.Our study shows that the care managers are contradictory regarding to their freedom of space. In the other hand they consider that their freedom of space is positive, but on the other hand when the municipal guidelines don´t work, they become worried and insecure.It´s the none working municipal guidelines who gives the care managers a huge freedom of space. Which leads to that the care managers is afraid of doing misjudgments. Our result don´t distinguish from other studies made in this subject area. .
