Under de senaste åren har det skett en integrering av informations- och kommunikationsteknik (IKT), exempelvis datorer, i såväl samhället som i skolans undervisning. Syftet med den aktuella litteraturstudien är att undersöka vilka samtalsaktiviteter som eleverna deltar i då de använder bärbara datorer eller handdatorer under matematiklektionerna, samt att belysa vilka möjligheter och hinder som framträder. Som teoretisk utgångspunkt ligger ett sociokulturellt perspektiv på lärandet där språket, den miljö som eleven befinner sig i och de redskap som används beskrivs som betydelsefulla aspekter för lärandet. I läroplanen förtydligas att elever ska ges möjlighet att delta i kommunikativa samspel och att modern teknologi ska användas så att eleven kan inhämta, lära och utveckla sin förmåga att kommunicera matematik. Tidigare forskning kring matematik visar att elevers kollaborativa lärande och användande av IKT främjar elevernas matematiska kunskaper och delaktighet i samtalet.

This master thesis has been a product realization process. Having BRIO:s walking cart as thestaring point the purpose was to further develop the principle of such products and at the sametime broaden their sector of use. The final result is to be regarded as a complete solutionmeant as a foundation for further development at the BRIO Company. The product aims tosatisfy the demands and needs of the target group called theon the go parent. Trends, qualityand purchase power are features that characterize this particular target group.The project resulted in a walking stool namedBRIO Circus after its source of inspiration.

The aim of this essay is to examine three separate Swedish public libraries and their respective websites on the grounds of the usability sciences. I firstly had to summarize the main properties of the usability-field in order to gain an extended knowledge of its purposes and possible usage for today?s library systems. I was then able to apply the extended knowledge in the examination of the three library websites and the purpose of determining whether or not they were designed according to the standards set by the usability-sciences.Usability is a rather new science that deals with the dissection and examination of computer-based systems, in order to find the key components that make systems user-friendlier. With user needs being the main focus of its research, usability tries to meet all the different needs of the modern user and construct systems that are less system-centered and more user-centered.

The purpose of this study is to describe some primary school teachers understanding of language development and approach of first and second language speakers with Arne Tragetons Writing to reading, for pupils in early ages.By using a qualitative method with interviews and participant observations and informal conversations, the basis for the survey was collected. Four teachers in three schools participated. The proportion of second-language pupils at each school was 35%, 17% and 0%. My theoretical starting point in the study was the hermeneutic research tradition, which has been used to interpret and understand the collected material. Theories of behaviorism, constructivism and socio-cultural perspective has been used in the analysis part of this study.

With the advance in computer and network technologies, multimedia systems and Internet applications are becoming more popular. As broadband network is prevailing, more clients are able to watch streaming videos or to play multimedia data over the Internet in real-time. Consequently, there is an increasing demand in the Internet for streaming video systems. As the run-time environment of such applications tends to be dynamic, it is imperative to handle transient overloads effectively. The goal of this work is to develop an algorithm that would provide a robust and controlled behavior of the video system so that important data is delivered on time to the video clients.

My curiosity concerning what pupils read and write during leisure time led me to gather information using a quantative method. The study's aim is to investigate which reading and writing habits they have during their time outside school. A comparison was done of pupils at school year level 3 and level 4 in two different schools with the intention of investigating the influence of social background on reading and writing habits. 137 pupils filled in survey forms and thereafter the MYSTAT statistic program was used to process the information. The results point towards that the pupils read story books both more often and for a longer time than any other type of literature and that they read them often or very seldom.

Debate over Intellectual Property Rights ?IPRs? particularly patent and copyrights is mainly on forward-looking industries in computer software. As part of a trade deal reached in 1994, the member nations of the World Trade Organisation must adhere to a global agreement known as TRIPS, for the Trade- Related Aspect of Intellectual Property Rights.This study is to analyse the ethical conception of Intellectual Property Rights and in particular its implications on the developing countries in relation to TRIPS. The approach will be to analyse a broad philosophical theories of property to see if there is any justification for a software program to be treated as private property and also argue base on John Rawls two principles of justice in relation to TRIPS Agreement. Some reflections will be put on the use of open-source software by less developing countries.From the study it was asserted that, strong IPRs protection would hinder technological transfer and indigenous learning activities in the early stage of industrialisation when learning takes place through reverse engineering.

Nackbesvär är vanligt förekommande vid datorarbete. Stående datorarbete har i visats ha en gynnsam effekt på nackbesvär. Nackflexion kan ge en ökad belastning på nacken. Syftet med studien var att jämföra flexion i nacken vid sittande och stående datorarbete för personer som utför datorarbete under en stor del av dagen i sitt ordinarie arbete.Sammanlagt tio personer, åtta kvinnor och två män, som arbetar på en företagshälsovård deltog i studien. De arbetade med datorarbete i växel, kundservice, sjukvårdsrådgivning eller sjuk och frisktjänst (en tjänst där arbetsgivare får hjälp att hantera sjuk och friskanmälningar, sammanställning av sjukskrivningsstatistik samt med rådgivning till sjukskrivna).

The dialysis ward at Karolinska University Hospital is a highly pressurized work environment filled with critical treatment situations where patient?s lives can be constantly in danger. Staff have to deal with a myriad of alarms and error codes in response to their patients varying ailments. The workforce at the dialysis ward lack controlled environment training, sufficient to address all of the potential treatment scenarios, with no risk of jeopardizing the patient?s condition.The purpose of this essay is to design and test the efficacy of using an IT based device for dialysis education at Karolinska University Hospital.The main topics this essay intends to address are:? Identification of user scenarios and training fields.? Prioritization of key training areas.? Utilization of IT in effective staff training.? Design of a conceptual prototype.The process focuses on the user and their needs.

A key part in the development and verification of digital systems is simulation. But hardware simulators are expensive, and software simulation is not fast enough for designs with a large number of gates. As today?s digital zesigns constantly grow in size (number of gates), and that trend shows no signs to end, faster simulators handling millions of gates are needed. We investigate how to create a software gate-level simulator able to simulate a high number of gates fast.

Denna uppsats har som syfte att, genom kvalitativa intervjuer, belysa fem kvinnors intresse för spel (dator- och tv-spel) och hur dessa kvinnor i sin tur talar om spel som en del av sin identitet. Frågorna som ställs till empirin handlar om vilka erfarenheter informanterna har av spel som intresse och vilka slutsatser om deras spelande man kan dra av detta. Vidare får vi en inblick i hur det normala ser ut inom spelvärlden, utifrån informanternas berättelser. Sist men inte minst så ställs frågan vad föreställningarna om det normala inom spelvärlden får för konsekvenser för informanternas identitet, och därmed vad detta leder till gällande de möjligheter och begränsningar som dessa kvinnor ställs inför, i relation till sitt intresse och den värld som omger det. Uppsatsen visar på att det inte bara finns en norm för hur en kvinna ska vara som Gamer utan det finns också en normativ femininitet som man bör förhålla sig till.

The aim of this thesis is to investigate how students in higher education use talking books. This has been inves-tigated through qualitative interviews with nine students. The intention has been to find out how they use talk-ing books and why they have chosen to do it in the way they have, looking specifically on whether there are strategies shared by most of the interviewees.As a theoretical basis of the thesis I have chosen a study, described by Sigrid Hongset, where dyslectic pu-pils tried using printed text and text on tape, as well as both simultaneously. George Kingsley Zipfs ?Principle of least effort? will act as a supplemental theory.The interviews show that the students use talking books in different ways.

Skuggor är centrala för hur människan uppfattar världen. Inom datorspel och andra interaktiva 3D-applikationer är det viktigt att underlätta förståelsen av scenen och det finns även ofta en stark vilja att skapa realistiska miljöer. Detta samt att skuggsättning är en komplicerad och prestandakrävande operation gör det till ett viktigt område inom realtidsgrafik. Vi undersöker i denna avhandling relationen mellan prestandan (renderingstiden) för de två populära metoderna för skuggsättning inom realtidsgrafik, shadow mapping och shadow volumes. Undersökningen avgränsas till två utvalda varianter av de ursprungliga algoritmerna.

The aim of this Masters thesis is to examine the library discourses concerning the phenomenon and concept of digital libraries in Swedish library press 1980-2002. What changes can be identified? The questions are: what is said about the conditions for the phenomenon; how is the concept of digital libraries used; who makes these statements; what are the relations between these discussions and the library context in which they are made? Five Swedish library journals, BBL/Biblioteksbladet, DIK-forum, Human IT, Svensk biblioteksforskning and Tidskrift för dokumentation, were examined. The method used was discourse analysis. The theoretical starting-point was Foucaults discourse theory.
