Elevers tillämpning av källkritik på Internet
This paper, called Pupils' practice of source criticism on the Internet, is investigating pupils? use of source criticism. The main research question was: how much knowledge pupils from an upper secondary class have about the use of source criticism, regarding examining data from the Internet intended for assignments. Furthermore, developing a suitable method to investigate this was included. The main research question led to further sub questions that aimed to answer to what extent pupils consider source critique criteria as sender, aim, up-to-dateness, credibility and dependence.The study has been conducted by using mixed methods, both qualitative and quantitative methods.
Informationssökning på Internet - att välja verktyg
The Internet offers an abundance of information. This information is easy to access in technical terms, however it is difficult to find. At present there is a wide variety of search services to choose from. This master's thesis is about selecting the appropriate search service for a certain question. Are different types of services suitable for different types of questions, and if so, which services for which questions?To answer this, I have undertaken one theoretical and one empirical study.
Rekryteringsprocessen vid Svenska Spel
In the constantly changing working life of today, where emphasis on human capital grows stronger, the importance of recruiting and retaining good staff increases. Successful recruitment requires a first-rate recruitment process. In literature on recruitment recommendations for successful recruitment are presented. The aim of this study is to describe similarities and differences between these recommendations and Svenska Spel?s recruitment practice on the basis of a description of the recruitment process at AB Svenska Spel, and also to identify possible reasons for differences between theory and practice. To meet the purpose of this study literature and scientific reports have been studied. Interviews with five HR-specialists and four managers have also been conducted. The recruitment process is therefore described out of the employer?s point of view.
Ett plus ett blir två : Introduktion av likhetstecknet i förskoleklass och årskurs 1
Today there is a shortage of skilled IT-technicians in Sweden. It is approximated that Swedish companies can hire 31 000 IT-technicians in 2015 and the need seems to increase in the coming years. One proposed solution to this problem is to make programming more desirable to youths. In this study we attempt to investigate the effects of an introductory course in computer science on youths? (16-17 years old) in a classroom setting.
Från alger till biodiesel - Den italienska drömmen?
This project aims to investigate whether algae can be used for biodiesel production in Italy. Algaes are a good option since they are fast growing and do not occupy arable land. The aspects that have been considered are growing, harvesting, which algae strain that is most suitable, extraction of oil, the production of biodiesel and where in Italy this could be possible due to climate. Cost? and energy calculations have been made to investigate if biodiesel produced from algae would be profitable. During the production of biodiesel there are several residues obtained. When the oil has been extracted from the algae, biogas is produced from the residual biomass by anaerobic digestion and then the electricity that can be produced is supplied to the production of biodiesel.
Skötsel av torvmarksskogar - vad vet egentligen Västerbottens skogsbolag?
About a quarter of the Swedish land area is covered with shallow or thick peat. There is a potential to increase forest production in Sweden with almost 2 million m3/year in selected peatlands with low conservation values. This increase can be accomplished by drainage, complementary drainage, ditch maintenance operations and fertilization. The purpose of this study was to determine the level of knowledge regarding the management of forests on peatlands and was restricted to selected forest companies in Västerbotten County, with offices in Umeå. Three companies were chosen, SCA, Holmen and Norra Skogsägarna.
IKT i skolan : Hur några pedagoger och barn ser på IKT i skolan utifrån Arne Tragetons modell Skriva sig till läsning
In this essay, I have examined what has been studied and presented in the theory of ICT in schools. I have based my theory on Arne Trageton?s book Att skriva sig till läsning ? IKT i förskoleklass och skola (2005) and theories on children?s reading and writing development.The purpose of this study is to determine how teachers and children experience teaching with Trageton?s ICT-based model Att skriva sig till läsning and whether the model is beneficial for children's first reading and writing.Through qualitative interviews with two pedagogues from the same school and some children from first grade, I have received answers to my two questions:How do pedagogues and children experience ICT-based teaching in the context of children's first reading and writing?How do pedagogues experience the reading and writing development in first- and second-language students when using ICT-based teaching?The results showed that both pedagogues and children were positive about the model in which the computer was used as a writing tool in learning to read and write. The teachers felt that the model was suitable for all children according to their conditions.The children saw the writing as very enjoyable. For the ICT-based teaching to work properly, the technology has great significance.
Inloggning : Lösenordskryptering och Brute force attack
This report is the result of a sub-project of a larger project to create a platform formathematical education. The sub-project focuses on authentication with associ-ated security, where security is emphasized. The project environment is Java EE 6where GlassFish 4.0 acts as the server. The project has been divided into threeparts; password encryption, Java EE authentication and brute force attack. Thepassword encryption part focuses on examining different hash functions executionspeed, the result shows that none of the examined hash algorithms is suitable fordirect use.
Kunskapsorganisation av ämnesområdet arktektur : Klassifikation eller indexering av samlingarna på en arkitekthögskola?
This thesis analyses the problem of how to organise a multidisciplinary domain of knowledge like architecture. The study is both theoretical and empirical. The theoretical part include discussions of theories of knowledge organisation. Two different principles of classification were examined in relation to the domain itself, as well as in relation to the educational programme at the School of Architecture at Lund University and comparable schools in Sweden. The empirical part is a case study carried out at the School of Architecture at Lund University.
Utvärdering av labpilot - flödesbatteri : Experimentell studie
Results have shown that flow batteries may be a solution in the future as an effective and environmental friendly method to an energy storage system (ESS). The technology is reliable and has a high efficiency that comes with low energy losses and a long lifetime. The range of possible fields is suitable for cutting energy peaks in the power grid, by always have a ready and available energy storage that balances the production. By comparing the advantages of flow batteries with conventional batteries it is mainly the fact that they can conserve energy for a long time without being self-discharged thanks to that the storage capacity is in principle endless and limited by the size of the electrolytes tanks that makes them a great energy storage system. The batteries won?t take any damage or decrease in performance when charging or discharging it or if you exhausts it to 100 % and leave it discharged for a long time.

In this thesis ?information? means non-fiction material and ?children? do not include preschool children. The method used is knowledge overview and the material (mostly Master theses in LIS published January 2001-June 2006) is related to user studies of children as information seekers.
Kompetenshanteringssystem i användning En beskrivande studie om hur ett kompetenshanteringssystem används i medarbetarsamtal inom en vård och omsorgsorganisation
In recent years, Information Technology (IT) has gained more importance in workinglife. More and more organisations has shown an interest about how technology can beused to manage the competence of the employees, and how IT can contribute to thedevelopment of the organisation. In order to achieve this, there is a need for suitabletools to support this process. Even though the implementation of competencemanagement systems (CMS) is a highly up to date question for many organisations,there is a lack of scientific reserach concering this area. This study will contribute tothe research area by examining how CMS is used by employees in daily working life.The manager and the employees in a healthcare organisation in Sweden were observedduring appraisals in order to observe how they used the CMS to evaluate competence.The appraisals were considered a suitable place for studing CMS in use within anorganisation.By using theoretical perspecitves such as the Sociomateriality and Situated Learning,the study can contribute to the knowledge of the entanglement between technologyand working practice.
A targeted evaluation of OpenEye?s methods for virtual ligand screens and docking
The process of drug discovery is very slow and expensive. There is a need for reliable in silico methods; however the performance of these methods differs.This work presents a targeted study on how the drug discovery methods used in OpenEye?s tools ROCS, EON and FRED perform on targets with small ligands. It was examined if 12 compounds (markers) somewhat similar to AMP could be detected by ROCS in a random data set comprised of 1000 compounds. It was also examined if EON could find any electrostatic similarities between the queries and the markers.
Livet efter sfi : Vilka tankar har några sfi-elever om sin delaktighet i det nya landet och hur har de lyckats med att förverkliga uppsatta mål?
Boplatsvallar, often translated as semi-subterranean settlements, is an ancient monument with a diffuse definition. Defined as ?embankments that partially or completely surround a often lowered/dug down surface- this category of ancient monuments is also made up of a former category which traditionally was interpreted as winter settlements from the late Stone age in Sweden. This view of the ancient monuments carried over, to a certain extent, to this new definition. Should this be the case, that this category of ancient monuments are remains of winter settlements, used recurringly over an extended period of time, then they should exhibit similar signals in regards to the distribution of the anthropogenically altered soil chemical and soil physical properties at the sites.The area around Lillsjön, Anundsjö parish in Ångermanland, have four boplatsvallar located separately in the regional area.
