Vänsterhandsteknik för klassisk gitarr

In this examination paper I?m using the qualitative method: phenomenographic analysis to present twenty educated and working pre-school teachers opinions about being outdoors in Swedish pre-school. The purpose is to describe the variation between different pre-school teachers? opinions, not to focus on wrong or right.    The paper starts with a review over the opinions presented by the literature on the subject.

Stockholms blodbad i historieboken: En l?romedelsanalys under perioden 1869 - 1996

This thesis explores in which ways the portrayal of the event known as the Stockholm bloodbath has changed during the period 1869-1996. This is done through textbook analysis. In Sweden, history has been a school subject since the 17th century, and has throughout its history had a formative role in the Swedish school system. In the middle of the 19th century it was specifically stated that the aim was to help students nurture a sense of national pride and love of country. The aim of the study is to investigate how nationally loaded events have been portrayed in text books, as well as if and how the evolution of said textbooks reflect the evolution of the history subject as a whole.

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..

Smålands museums bibliotek : underlag för en handlingsplan för biblioteksverksamheten grundad på de anställdas informationsbehov

Smålands museum, the museum of Småland, is a museum for the county of Kronoberg, a mission given to the museum by the state and county council. The main fields of the museum are the cultural heritage and the history of culture of the region. The museum of Småland is also the Swedish museum of glass. This Master s thesis focuses on the information requirements of the employees at the museum of Småland. Because of the financial status of the museum, the librarian that worked at the museum had to quit about four years ago.

En upplysning om sexualitet : diskursanalys av det svenska samhällets syn på ungdomars sexualitet

The purpose of this essay is, using discourse analysis, to define how the Swedish society sees sexuality and how this is conveyed to young people. The questions at issue are; How is the term sexuality defined and delimited? How are the young people described in relation to sexuality? Are young people ascribed to different needs and qualities in relation to sexuality depending on their gender?There is previously a lot of research with great multitude about the sexuality of the youth. The research methods vary but text analysis within the subject area is unusual. The material used in this discourse analysis have been published by normative public institutions.

Mjölkkors behov av att ligga och att sova

The aim of this literature review was to investigate whether the modern dairy cow has the time she needs to lie down and to sleep and what deprivation of these behaviors could lead to. Current research seems to agree on the fact that sleep is essential but there is no uniform explanation of the function of sleep, even though there are many theories. It is known that sleep has an important impact on the immune system and that sleep is increased in case of an infection. Sleep deprivation causes many negative effects including reduced function off the immune defense, increased metabolic activity, malnutrition and increased heart rate. It has also been found that deprivation of sleep could cause increased mortality.

Indexeffekten : En studie gjord på Nasdaq OMXS30 och OMXH25

AbstractMaster thesis in Business Administration, School of Business and Economics at Linneaus UniversityAuthors: Patrik Larsson and Pontus GislénSupervisor: Håkan LockingExaminer: Sven-Olof CollinTitle: The index effect- a study on Nasdaq OMXS30 and OMXH25Introduction: A significant part of the financial literature is based on the Efficient Market Hypothesis which assumes that prices in the market reflects all available information. Anomalies, such as the index effect, indicate weaknesses in this theory as it has been proved that it is possible to outperform the market using public information. Hence, the index effect can be linked to market efficiency which makes it interesting to study from a theoretical perspective. The mapping of the index effect is also interesting from a practical perspective, as it leads to a better understanding of whether investors and firms should take this anomaly into account.Problem: Is there an index effect, how does it behave and what can explain this effect?Purpose: The aim of this study is to investigate the index effect.

Avancerad scenarioanalys för ambulansplanering

This paper describes the development of a simulation model for the ambulance flow in the Västra Götalands-region of Sweden, and an analysis tool for the output of the simulation model. The aim of the simulation model was to be able to evaluate the outcome from changes in the ambulance operations, such as a reorganization of ambulances or an increase in intensity of the ambulance calls. This evaluation is meant to serve as decision support for the strategic planning of the ambulance operations. The analysis tool was developed to visualize the abundant geographical data produced by the simulation model in a meaningful way. The simulation model was validated against historical data which showed that the dispatch time for the highest prioritized ambulance calls corresponds well with historical data.

En undersökning om fallolyckor med gångtrafikanter

The purpose of this study was to investigate different relations between the damages of falls and background variables as well as the relation between the falls and the weather condition to later be able to use this report to expand the knowledge among workers at VTI about the pedestrian fall injuries. All of the fall injuries in the data that this study is based on have occurred in Sweden during the time period between January 2003 and December 2011.To be able to answer the questions that this report is based on several statistical methods are used. The statistical methods that have been used during the making of this report are multiple linear regression, binary logistic regression, correlation analysis, association analysis and descriptive statistics as well as visual analysis.The results of the study show that women around menopause age have a tendency to get a big increase in the amount of injuries compared to men of the same age. The study also suggests that men on average tend to have a lower level of injury compared to women.Age also seems to affect both the amount of injuries and the level of injury negatively. The study suggests that the most likely reason for this is both that the intake of ?Fall Risk Increasing Medicine?, which is medicine that increases the drowsiness, is higher among older individuals as well as lower estrogen levels among older women and lower amount of testosterone among older men, which causes a loss of bone density in both sexes.The weather seems to have a strong effect on how many injuries occur but also a noticeable effect on the scale of the injury.

Simulering av simulinkmodeller med Extended Kalman Filter

Simulations of simulink models using Kalman filters are often very time-consuming. This problem depends mainly on the fact that the Kalman correction has to be performed at each sample instance through the whole simulation. The goal for this thesis work is to reduce that time-consumption for the filtering part (the integration partis treated in a complementary report) of a simulation. Furthermore a Matlab routine to perform parameter tuning and finally a graphical user interface is developed.The filtering part of the simulation in this thesis is based on an Extended Kalman Filter (EKF). The time optimization of this filter considers searching for the possibility to replace the today?s existing Matlab functions that is used to perform the filtering calculations.

En bra skola för alla eller bara för eliten? - En analys av tydligheten i Läroplan, examensmål och gymnasiegemensamma ämnen för gymnasieskola 2011

The purpose of this essay has been to study the comprehensibility and the plainness of chapter 1 and 2 in ?Läroplan, examensmål och gymnasiegemensamma ämnen för gymnasieskola 2011? that is one of the governing documents of Swedish upper secondary school. The Swedish government approved a national language policy in 2005 which involved an aim that the official Swedish language would be refined, easy and comprehensible. Plain language has since the eighties had a prominent place in Swedish research and science and is now a thought-out principle at almost every public authority. This essay has performed a linguistic text analysis, a plain language analysis, a plain language test and a critical discourse analysis on the two chapters from ?Läroplan, examensmål och gymnasiegemensamma ämnen för gymnasieskola 2011? that is common for all upper secondary school programs.

Anytime-whatever : Om narrativ struktur och temporal upplösning i Stig Larssons Autisterna

This essay is reading the Swedish author Stig Larssons debut Autisterna [The Autists] (1979) in the light of Gérard Genettes narratology and the time philosophy of Gilles Deleuze. The focus of the essay is time and how it is seemingly dissolved. The essay maps out a chronology of the non-chronological novel and from there discusses the breaking up of the empirical time. The essay uses Deleuze to explore the time-image of the novel to see how it is built up in the text for example by literary anyspace-whatevers. Hence the title, Anytime-whatever.

Analys av parathormon och joniserat kalcium i blod hos hund :

The calcium homeostasis in the body is normally strict regulated to be kept within very narrow limits. This regulation is due to the action of parathyroid hormone (PTH) which is synthesized in the chief cells of the parathyroid glands. In different diseases, the calcium homeostasis is disturbed and this could either be due to a dysfunction of the parathyroid gland itself, or it could have a completely different explanation. To investigate disturbed calciumhomeostasis, ionized calcium and PTH can be analyzed from a blood sample. There are a lot of different assays to measure PTH in humans.

Missionssyn och missionspraktik i Evangeliska Fosterlandsstiftelsen : speglat av brev och bloggar från Etiopien

In this essay there will be four text books from grade 1 studied, the first one are from the year 1976 and it will be going forward to the year 2012. The aim of this study is to see how the genders are depicted and represented, as well as what roles the genders are given. I do also want to see if there is a notable change in this over time. I will be doing a study based on the quantity of the contents, and I will also be doing a critical discourse analysis.The result of the study showed that there were more gender-based constructions that referred to women in all of the four books, which indicates that women are represented more often in these reading books. It is most common to portray the genders in their stereotypical roles, which again are present in society, but sometimes these roles are depart from what?s present in society.

Ingen ser mig ? finns jag? : En uppsats om exkluderade barn i leken

The aim of this study is to describe successful strategies to include children in free play activities at the preschool. The methods that pedagogues use to act and work with excluded children will be examined. To get answers to my questions I have conducted interviews with five pedagogues in four preschools. During interviews they mention two different approaches to encourage free play activity. One way was to participate and play along with the children.
