Gruppolarisering innebär att bl.a. social jämförelse leder till att isolerade grupper med likasinnade genererar mer extrema åsikter. Gruppolarisering på internet kan vara ett oroväckande fenomen för den deliberativa demokratin. Istället för att människor med konkurrerande ståndpunkter utbyter idéer och tankar med varandra samlas de i isolerade diskussionsforum på internet där social jämförelse i värsta fall kan utmynna i hattal och terrorism. Med netnografisk metod studeras här politiska diskussioner online i två olika typer av forum, ett politiskt och ett icke politiskt.

The gaming market has become the fastest growing market for leisure and is one of the most popular forms of homeentertainment. This has generated a media debate about how people are affected by gaming and concernes how we are affected by the violence that may occur in games. Games proponents argues that gaming is the future of teaching and computer games are becoming a sustainable and popular instruction strategy. Some studies have long used computer games for educational purposes. By interviewing high school students in focus groups as qualitative research, I studied their attitudes towards computer games as a learning tool.

I enlighet med den trend som råder inom den tekniska utvecklingen i samhället i stort, introduceras nu ett sätt för bankers kunder att ha personliga rådgivningsmöten via Internet. Tidigare har sådana möten skett ansikte mot ansikte på det bankkontor som kunden tillhör. Det finns en rad fördelar med att tjänster sker online som exempelvis tideffektivitet, geografiskt oberoende och mer flexibelt i allmänhet. Den här kvalitativa studien handlar om en underökning kring hur personliga (finansiella) rådgivare upplever att arbeta med den här typen utav möten, närmare bestämt vilka faktorer som de anser viktiga när möten som skett ansikte mot ansikte kan komma att ske online. Studien innefattar ett induktivt tillvägagångssätt i syfte att ta reda på dessa faktorer samt att granska dem utifrån ramverket datorstött samarbete och synsättet kroppsbaserad kognition.

The problem of finding targeted medicine is a central problem in chemotherapy. From this point of view the ubiquitin-proteasome system is a highly promising object in the pharmaceutical approach. Proteasome plays a critical role in cellular protein degradation, cell cycle and apoptosis regulation.Proteasome inhibitors are substances blocking the actions of proteasome. Cancer cells are more sensitive to inhibition of the ubiquitin-proteasome system than normal cells. Therefore proteasome inhibitors have the potential to be successfully used in the cancer treatment.The study aimed to test various substances to identify possible proteasome inhibitors with the IncuCyteTM FLR image system and fluorometric microculture cytotoxicity assay.

A well known optimization-problem of multiprocessor system is scheduling of tasks. In this paper I use a variant of previous known algoritm, (Fast Critical Path) for scheduling real-time tasks on a multiprocessor system. This is made in a simulation study in MATLAB. The system architecture is assumed to be a MIMD- machine, (Multiple Instruction stream Multiple Data stream) with bus-typologi and message-architecture. Scheduling was made on this system where the number of processors varying from five to ten.

There exist several known methods for calculation of radio coverage for ground-based systems. As far as we know there are no equivalent methods for the case of flying platforms when the altitudes and speeds are significantly different to those of ground-based systems. This thesis describes the theoretical concepts behind calculations of radio coverage for flying platforms. An investigation is made to sort out what is important and possible to employ in a model for simulations. A method is described and implemented in a program for evaluation of flying radio systems.

AbstractIT can facilitate communication among individuals and connect people across geographical distances. On the contrary, citizens of the society who do not use communication technologies to some extent might feel excluded from the information society. As elderly citizens are already in a vulnerable position for the digital divide, communication technology becomes an important tool for interacting with friends and family. The social situation of elderly, 60 years of age and older, is a topic of current interest since they are the fastest growing age group in the world today. Further, social interaction becomes more important among elderly since it has a positive effect on well- being.

Den ökade betydelsen av att som företag ha ett starkt varumärke för att synas på marknaden har inneburit att det läggs ner allt mer tid och resurser på varumärkeshöjande aktiviteter inom företagen. Den växande virtuella världen och den ökade handeln på Internet har i kombination med vikten av ett starkt varumärke skapat en komplicerad situation. Vagabond är ett svenskt varumärkesproducerande skoföretag som har ställts inför de möjligheter och svårigheter som den ökade Internetanvändningen har inneburit. Expansionen genom försäljning via återförsäljare på Internet har inneburit att svårigheterna med att kontrollera hur varumärket framställs på olika sidor på Internet har ökat. Den totala skokonsumtionen har ökat de senaste åren och konkurrensen på skomarknaden har blivit stor, vilket bidrar till att vikten av att sticka ut blir allt större.Syftet med vår studie är att förklara hur det varumärkesproducerande företaget, i vårt fall Vagabond, arbetar med att framställa och bevara sitt varumärke och vidare hur de Internetbaserade återförsäljarna resonerar kring sina produkters varumärken.

These are lube and control oil systems.The project is restricted to two of Siemens maintenance products, No Stop Check (NSC) and the annual Safety Inspection (SI).

By tradition, archival sciences has emerged in a context with defined information processes, with explicit information producers and custodians to which consumers make requests for the information. In this process, the archival science has developed methods and strategies to preserve authentic and reliable records and by that providing trustworthy information. In an online society, people are using the internet to get information for different purposes. Even though there is no legal obligation to guarantee the authenticity, it is of societal importance that the end users get trustworthy information. In this online context, open data is a trend that is growing fast over the world and it is interesting because its conditions raises many questions regarding authenticity.Since open data is free to reuse, link and combine with other information, and it is preferably in primary format it raises questions about how to maintain the integrity and identity of the information, which is the constituents of authenticity as it is used in this work.

The mission was to create a prototype of a menu system for the companySystem Andersson AB. The instructions were that it has to be as interesting andmodern now as in 20 years. We had to look at technology from the cutting edgeof development to make our prototype survive in the future. WindowsPresentation Foundation (WPF) was the technique we focused on. There areonly a few applications that take advantage of WPF today, but it is predictedthat WPF will be the next generation method for developing applications to theWindows platform.To make our menu visually appealing, easy to use and at the same timefunctional, we followed the clear path and guidelines that are available ininteraction design.

Arbetet handlar om analys av staden och behandlar frågan om hur man kan analysera staden på ett så heltäckande sätt som möjligt. Jag har använt två olika analysmetoder: Realistisk stadsanalys och Finding lost space. Dessa två består i sin tur av flera mindre delar där olika infallsvinklar ges spelrum. Analysen ska leda fram till ett konkret planförslag, och arbetet behandlar därför hela analys- och designprocessen. Arbetet har organiserats utifrån en arbetsmetod med fyra steg: Historiska studier; Analys av stadens nuvarande rumsliga sammanhang; Syntes samt Planförslag. Hela analys- och designprocessen genomförs i en verklig stadsmiljö: området kring Kungsplan i centrala Karlskrona.
