Låt det förflutna tillhöra det förflutna : En studie om datorspel, socialt välbefinnande och kunskapsmässig utveckling
This study investigates the effects that commercial computer games have on young individuals social comfort and learning progress. As a systematic study of literature, scholarly articles have been analysed in order to illuminate the positive as well as negative effects on social comfort and learning progress that may come with playing computer games. The social effects have mainly been discussed with role-playing games, such as World of Warcraft, as starting point, while the learning effects have been coupled with strategy games, such as Civilization IV. The study does not simply declare how these games can be good for these factors, but also in what respect computer games may prevent the development of young individuals socials skills and learning progress. The study showed that in spite of perpetual prejudices against computer games in the technological age, computer games might actually be good to use as a tool in order to authorize the development of young individuals regarding learning and social aspects.
Hälsa och datorkonsumtion bland pojkar i årskurs nio : En komparativ tvärsnittsstudie
The aim of this study is to investigate the prevalence of computer consumption among boys in ninth grade, and to see if there were any differences with regards to physical activity, sleeping habits, breakfast habits and BMI. The study has cross sectional design with a comparative and a quantitative structure and is based on a former study called ?Food & Health 2007?. The respondents were represented by 181 boys in ninth grade, recruited from ten different schools in the county of Uppsala, who were answering questions about media consumption, breakfast habits, physical activity and sleeping habits. Daily computer consumption was reported up to one hour for 12 % of the respondents, one to three hours for 65 % and over three hours for 42 %. The boys who had a high physical activity level were less frequent in computer consumption while those who had a low physical activity level spent more time by the computer.
Datorbaserad examination: En studie om användarhinder och systemacceptans bland lärare
The aim of this thesis is to examine how teachers use computer based assessment in their work and what user barriers they experience while working with computer based assessments. The result of the thesis is meant to provide an understanding of which factors affect the use of computer based assessments and how a company who provide computer based assessments applications can increase the rate of use amongst teachers.To investigate this, the author examined a company in Sweden who provide a computer based assessment application for both universities and high schools. The study was carried out at two different schools, a university and a high school, both located in Stockholm. In total nine teachers were interviewed. The author also conducted observations at the company whose computer based assessment application was examined.The author?s findings suggest that a lack of functions within the application and lack of costumer support from the company all negatively impacted the teacher?s use of the application.
Peer-to-peer som företagslösning
Problemområde:
Idag är användandet av peer-to-peer (P2P) - applikationer såsom KaZaa, ICQ och
Seti@home utbrett bland privatpersoner. Användningen inom företag är dock ännu
i sin linda.
Vi kommer därför i den här uppsatsen utreda om ett eventuellt införande av P2P-
teknik i ett företagsnätverk ger några fördelar jämfört med en klassisk
Client/Server-lösning.
Hypotes:
Arbetet bygger på hypotesen: ?En P2P-lösning ger fördelar för företaget
jämfört med en Client/Server-lösning?
Genomförande:
För jämförelsen mellan P2P och Client/Server definierades och jämfördes fem
områden: Säkerhet, Användbarhet, Tillgänglighet, Bandbredd samt
Utrustningskrav.
Slutsats:
Inom områdena Användbarhet och Tillgänglighet ger en P2P-lösning klara
fördelar, däremot inom områdena Säkerhet och Bandbredd visar Client/Server-
lösningen istället klara fördelar. Området Utrustningskrav är oavgjort då det
inte
finns någon märkbar skillnad på lösningarna.
Säkerhetsproblemen är P2P-teknologins akilleshäl och det problem som är mest
troligt att stoppa stora investeringar i framtiden om det inte löses.
Slutsatsen av vår jämförelse blir sålunda:
För ett företag som redan har ett existerande Client/Server-nätverk är det inte
någon idé att helt byta system, däremot kan det vara av intresse att
introducera en applikation som möjliggör skapandet av så kallade Virtuella
Nätverk.
För ett helt nytt företag kan skapandet av ett P2P-nätverk vara ett väl så
intressant alternativ till Client/Server.
XML som informationsbärare för EDI
Information handling has been a key issue for different companies for a long
time. Electronic Data Interchange (EDI) is used to transfer different business
documents from one company to another. This is done in such way that the
information itself is separated from how this information is stored and handled
in the companies internal systems. As different companies have different
systems there is a need for a standardised format for this exchange.
There is a big difference between EDI-systems based on what kind of
EDI-standard is used. The most common standard in Europe is EDIFACT, but with
increased interest of using the Internet for business communication there is a
need for a standard that is adjusted for use over the Internet.
Den Moderna Webben: Kan HTML5 konkurrera med traditionell programvara?
Vi ser en förändring i hur vi använder applikationer. Från att tidigare varit
associerat till en dator och begränsat till ett par operativsystem finns de
numera överallt. Fler plattformar innebär att man måste utveckla en applikation
till var och en av dessa. Detta gör att utvecklingstiden och kostnaderna ökar
och efterfrågan av crossplattformlösningar i form av webbapplikationer har
därför ökat.
Vi tittar närmare på hur det går att använda sig av HTML5, och övriga tekniker
som en modern webbläsare har integrerat stöd för, för att utveckla webbaserade
applikationer. Vi tar reda på om det finns några hinder eller begränsningar i
detta och om det finns några fördelar i att använda webben som plattform.
Resultatet indikerar att med de nya tekniker som är på ingång kan man utveckla
webbbaserade applikationer med prestanda motsvarande Java eller C#.
Kvinnor, datorspel och identifikation : en genusanalys av två datorspel och två kvinnors datorspelande
This essay covers computer gaming as seen from a perspective of gender theory. The main purpose of the essay is to examine women?s relationship to computer games, and more specifically women?s attitudes to the games they play. The theoretical basis for this essay is sprung from a hermeneutic perspective. The empirical basis for analysis consists of two in depth interviews and game analysis of the two computer games Counter Strike and Final Fantasy XI.
Interaktion i klassrummet
I den här rapporten beskrivs hur elever mellan åtta och tolv år upplever
användningen av datorn och Internet i skolan. Genom att studera användningen av
Internet med hjälp av intervjuer, deltagande observationer och informella
samtal har författaren i den här rapporten valt att utifrån elevernas
perspektiv beskriva deras situation. Utifrån den etnografiska studie och de
konstruktionistiska teorier författaren gjort utnyttjas sedan erfarenheter från
utbildningstiden för att försökta skapa ett koncept om hur ett framtida
klassrum skulle kunna komma att se ut.
Undersökningar har gjorts om hur information, kunskaper och erfarenheter utbyts
i klassrummet och vilken betydelse det har för användningen av Internet. Men
även hur elevernas själva utvecklas och skapar sig ett kritiskt tänkande och
att lära sig sortera, för dem, relevant information. Jag har även studerat hur
lärarens roll förändras och hur det påverkar undervisningskulturen.

exciting, while others may find it hard to see the opportunities for learning
and development.
Programmering till webben : Vad du ska utveckla din webbplats i för programmeringsspråk och varför?
This work is done to try to solve a scientific computer problem and its basis derived from the web, as there are a variety of ways to program to it. The most common languages used by developers, both private and corporate are PHP, .NET and Ruby. But why do companies or a private developer choose a specific programming language? Is it because it is better and has more features than the others, or because they are forced? This essay uses a questionnaire and through tests sees which is best and which one is the most popular/used. To illustrate the problem, a survey is conducted and sent to several companies and asked them to answer the questions regarding the issue.
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.
