Att vinna eller försvinna när alla får varsin dator : En-till-en-satsningar och dess inverkan på delaktighet, självbild och lärande för gymnasieelever i behov av särskilt stöd
The purpose of this study was to investigate how high school students felt that the computer helped or hindered participation and self-esteem in the learning situation and if the students experienced any differences between when they had been relatively alone in using a computer compared to when everyone had their own computer. The starting point was the national one-to-one projects made to give every student access to a personal computer and how it affected students in special educational needs and previous research. The theoretical approach was based on socioculture/activity theory and theories of self-esteem. Ten high school students in grade one at a senior high school that previously had started up a one-to-one project was interviewed. The results showed that the students primarily used the computer to write and to search the Internet, but even as a alternative or compensatory tool.
Svartgran ? ett alternativ när allt ser mörkt ut? : en kartmodell för att visa lämpliga ståndorter för odling av svartgran
A common problem in forestry is plant death caused by frost. The risk of frost is highest on wind protected, flat or low-lying areas in the terrain. Here you often have regeneration problems with Norwegian spruce which is especially sensitive to spring frost. Swedish tree experiments have shown that the black spruce can be a suitable alternative on these areas, for example on moisture frost prone areas. The species originates from North America and its pioneer tree characteristics make it more frost hardy than Norwegian spruce.
Systematisk riskexponering i svenska hedgefonder: Svenska hedgefonders exponering mot riskfaktorerna i Fung & Hsieh (2004) under perioden 2006-2007
This paper aims to investigate the systematic risk exposure of Swedish hedge funds using a modified Fung & Hsieh (2004) asset-based style factor model. The results show that the average Swedish equity hedge fund and fund of funds had a significant positive exposure to the equity market portfolio and the spread between small cap and large cap stocks (SMB) during the sample period. This is consistent with our a priori expectations and previous international studies. We do not find the expected systematic fixed-income related risk exposure for the fixed-income hedge funds and fund of funds in the sample. The empirical material used in this study is taken from a publicly available fund database maintained by the Swedish Financial Supervisory Authority (Finansinspektionen).
Flickors kroppsuppfattning och måltidsmönster : Förändring under pubertet och moderns betydelse
Within the ambulance care in Uppsala County a vacuum splint is used to immobilize fractures on extremities. The research available on which method of immobilizing to prefer during pre-hospital treatment is limited. The purpose of this pilot study was to examine the perceptions of the ambulance personal in Uppsala County on the issue of usability of SAM-splint and vacuum splint when immobilizing extremities. The project was also aimed at researching if SAM-splint could be seen as an alternative or a complement to vacuum splint, and to get an apprehension on any evident differences in patients? perceived pain when treated with the two different approaches. A descriptive comparative study was carried out. All patients, regardless of age and sex, with the need of immobilizing supposed fractures, were included. Patients with suspected femur fracture, collum fracture, or where pre-hospital care was not possible or in question, was excluded.
Detektering av in- och utandning vil bilkörning med hjälp av Matlab
Volvo Human Monitoring (VHM) is an ongoing project at Volvo Cars where they measure, amongst other parameters, inhalation and exhalation through a device called Respiratory Inductance Plethysmograph (RIP), on drivers. RIP measures changes in the cross-sectional area of the chest and abdomen. When the driver is in motion, such as when she is turning the vehicle, the cross-sectional area changes and noise in the RIP signal may arise.The noise results in a large number of manual adjustments in the analysis of the RIP signal, which is very time consuming and the validity of the device for measuring inhalation and exhalation is questioned.The purpose of this study was to improve the efficiency of the analysis of the RIP signal. The goal was to create a new data processing tool in Matlab that automatically detects inhalation and exhalation from a RIP signal with higher validity compared to the previous data processing tool.In this study, nine tests were performed on drivers while they were driving in different scenarios such as highway, country road and in city traffic. Inhalation and exhalation was measured using a RIP, a pneumotachograph with a tightly sealed facemask and a thermocouple placed between the nose and mouth, which was used as reference to the RIP.The result of this study was a data processing tool that automatically detects inhalation and exhalation with higher validity compared to the previous data processing tool.
Nyttjande av ofrörbrukat byggmaterial : En rapport åt Peab Jönköping
This final year project is made for Peab Jönköping and its target group is the construction industry. The main focus is the use of unutilized building material in the most economical and environmental-friendly way. Unutilized building material is here defined as material purchased for a construction project that for different reasons not has been used. The most important thing to find out was how much building material considered as being waste is actually useable material, and how much less it costs to use that building material instead of throwing it away.When this information was gathered a proposal on how to efficiently use the unutilized building material instead of wasting it was designed. Costs and incomes were investigated and the proposal suggested a storage area where Peab can store their unused building material.
Varför är det så svårt? - En studie av kulturhistoriska museers arbete med hbtq-perspektiv i samlingar
The aim of this two years master?s thesis in Archive, Library and Museum Studies is to analyse how Swedish cultural history museums work to include LGBTQ-heritage (LGBT is the acronym for Lesbian, Gay, Bisexual, Transgender and Queer) in their collections. This work is articulated around three research questions. These interrogate museum practice about collecting and collection management, what it looks like in the already gathered collections as well as the implications such work implies on a broader level. The theoretical framework throughout the paper is gender and LGBT studies as well as queer theory.
Banden mellan historia och arkiv
Freedom of religion or belief is indisputable in Human rights discourse, more discussed is exactly what it is that is included in the concept of freedom of religion or belief (in Swedish: religionsfrihet). This thesis focuses on the freedom of religion or belief in a European context, in particular on the European court of human rights and article 9 in the European convention for human rights. Some criticism has been directed against the Court to the effect that its practice and verdicts don't answer to the pronounced desire to develop a pluralistic and inclusive form of freedom of religion or belief.My aim is to examine, analyse and test three different theories, which all try to develop alternatives to the expression freedom of religion or belief, in relation to six verdicts from article 9 in Europe convention. My basic purpose is to try to find new ways of talking about freedom of religion or belief that might lead to a more inclusive, pluralistic and equal interpretation of that concept.The three theories wich I use are elaborated by Richard Amesbury (associate professor at Claremont school of Theology); Hugo Strandberg (TD at Åbo Akademi) and Eberhard Herrmann (professor in philosophy of religion at Uppsala University); and Martha Nussbaum (professor of law and ethics at the University of Chicago). The six cases from the European court are: X v.

Comparison of four transport systems for enetric pathogens
ABSTRACT: Commercial swab transport systems are used for collection and transporting of fecal and other microbiological samples. This system must maintain viability and contribute to survival of microorganisms during transport to the laboratory. Four swab transport systems have been compared, eSwab, ?- Transwab and fecalSwab, all three with flocked swabs, and Copan Venturi Transystem with rayon swabs. The study followed the recommendations from the Clinical Laboratory Standard Institute; document M40-A for recovery of Samonella, Shigella, Yersinia and Neisseria gonorrhoeae after storage for 0, 6, 24, 48 and 72 h at room- (22-25°C) and refrigerated (2-8ºC) temperature.
Bankers syn på ändringar av aktiekapital, revisionsplikt och redovisning : En fallstudie av svenska storbanker i Karlstads kommun
The amendment of a law which is expected to come may well have a significant impact on the Swedish real-estate broke market. The law change will probably have an effect in the number of ways real-estate brokers will compete as a result of the increasing variety of services offered. In order to gain competitive advantages brokers must be at the forefront in the development regarding the changing market. To do so requires that the company chooses an appropriate range of peripheral services that are profitable. The problem is to choose the ?right? services to convey. The purpose of this paper is to describe the services that are in demand for transmission and how the agents can work to meet the demand of this new market.
Validitet av observationsbaserade mätningar av armarbetsställningar hos pappersbruksarbetare
Abstract Objective: The aim of the present study was to investigate if inclinometer estimates of arm posture during paper mill work differed between periods of different arm visibility. The aim was also to identify strategies for and difficulties in assessing body-visibility on video. Methods: The study consisted of two parts, where part 1 aimed to investigate the validity of observation-based assessment of arm posture during paper mill work. Study 2 was a survey among people with experience in assessing the posture of paper mill workers from video. Results: The total time for the right upper arm visibility indicates that it was on average visible in 54%, partly visible 15 % and not visible 31%.
Energianalys av Svensk Växtkrafts biogasanläggning i Västerås
Svensk Växtkraft is the owner of the biogas plant in Västerås. The company is planning to increase
their treatment capacity at their biogas plant. In connection to this work it is also possible to make
some energy saving changes to the biogas plant. The objective of this study was therefore to make
an electricity and heat survey of the biogas plant, a detailed study of the heat consumption in the
sanitation step and also a comparison of energy consumption with the present sanitation method
and an alternative strategy where the waste is treated in 55 °C during 10 hours (the current method
is heating to 70 °C during 1 hour).
The energy survey was conducted in close collaboration with staff at the biogas plant. The current
during normal operation was measured, power was calculated and multiplied by the time of usage to
obtain the energy consumed.
Djupströbädd -bra för miljö och djur?
Deep litter is a system for animals kept in separate stalls, loafing and bedding in wind shelters. The litter can consist of different bedding, like straw and peat. The system is allowed to build over and to ensure optimal proportions it is necessary to add new straw regularly and to have good conditions. Important conditions are aerobic state, humidity, amount of organic substance and acceptable temperatures in the litter. The micro organisms are depending on temperature for their living conditions and to get the bottom layer in the litter to start burning.
