Arkivteoretiska krav på informationen i molnet : En studie om vilka kunskaper som leverantörer av molntjänster har angående arkivteoretiska kvalitetskrav på information

Idag pratas det mycket om ett fenomen som kallas Cloud Computing, vilket kan kort beskrivas som tillhandahållning av datorresurser så som informationslagring, processorkraft och applikationer via Internet. Begreppet Cloud Computing har ingen direkt motsvarighet på svenska men kan översättas till exempelvis molnbaserade datortjänster eller molntjänster. Vanligtvis så innebär Cloud Computing att it-företag hyr ut en del av en server samt annan datorservice till en organisation. Cloud Computing är ett attraktivt alternativ för både den privata och offentliga sektorn och efterfrågas i allt större utsträckning. Från ett arkivvetenskapligt perspektiv associeras Cloud Computing med många fördelar, men kanske med ännu fler nackdelar. De centrala problemföreställningarna relateras till tillit i en digital miljö.

En undersökning i datasäkerhet för hemanvändare - Är det nödvändigt att använda brandvägg?

The emphasize of this study is to evaluate security issues for home users having a personal computer connected to the Internet. It focus on the usage of advantages and disadvantages when using a firewall while connected to the Internet. The hypothesis is that it gives a better protection to install and use a firewall compared not to do so, due to security flaws in the operating system. The prediction was tested on a home user's personal computer. The testwork was divided into two major tests, each of them performed with, respectively without, a firewall. These major tests were divided into five smaller semi­ tests. The first semi­test without a firewall suffered from a virus or worm attack resulting in loss of data and log files.

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.

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.

Data Propagation and Self-Configuring Directory Services in a Distributed Environment

To ensure accurate and safe radiological reporting, Swedish software-firm eCare AB delivers a system called Feedback?the first and only quality assurance IT support product of its kind. This thesis covers several aspects of the design and implementation of future versions of this software platform. The focus lies on distributed directory services and models for secure and robust data propagation in TCP/IP networks.

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#.

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.
