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.

Vad gör biblioteken på Facebook och Twitter? En studie av fyra folkbiblioteks användande av sociala nätverk

The aim of this Master thesis is to describe why and how public librariesuse the social networks Facebook and Twitter. The focus is to study whatbrought about their use, how the work is carried out, ideas and objectivesbehind the use and what libraries actually convey on the networks. Themethodology is twofold: semi-structured interviews with responsiblepersonnel at four Swedish public libraries, and an ethnographic contentanalysis of four months of the libraries' status updates and tweets onFacebook and Twitter. The theoretical framework consists of a model forthe roles of the public library in society, and of discourses about thepublic library in media.Results indicate that social networks are used to market, make accessibleand inform of the library's resources and services. Furthermore, networksare used to communicate/interact with followers and to inspire people toread.

NAC can verify that the client who connects to the network has the latest antivirus updates and latest operative system hotfixes. Clients who don?t meet the criteria can be placed in quarantine VLAN where they only have access to the update servers.

Forensic Carving from Unallocated Space

Computer Forensics investigations have become more and more common while investigating IT-related issues. From experience, hard disks, USB thumb, memory sticks contains information that might be useful. Computer Forensics is regulary conducted by Police, Customs, Tax investigators but also within private companies and organisations. However, there are areas within the storage device that are not part of the organisied structure that a file system gives. The reason for that might be that the information has been erased by intention, a virus destroyed the file system and so on.

Produktplacering i videospel och dess påverkan på spelarnas attityd, återkallelse samt uppmärksamhet gentemot varumärken.

The gaming market is growing and the number of people, men and women, who play computer games, is also increasing every day. In addition, computer games are also interactive media which leads to the fact that product placement in computer games attracts and is used more frequently by marketers. It is therefore important for marketers and game developers to understand how product placement in computer games affects players' attention and attitude towards the brand or product that is product placed. We therefore examine how product placement in computer games affects players' recall of and attitude towards the brand. The aim is to help companies and game developers to see the effect of product placement in computer games on players and thus product place more efficiently.

Scientific collaboration kartläggning av ett tvärvetenskapligt forskningsområde inom biblioteks- och informationsvetenskap

The aim of this thesis is to map the research area of scientific collaboration within Library and Information Science LIS. The purpose is to find out who is doing research in this area, who they cite and if they get cited by other scientists outside of LIS. Scientific collaboration is an interdisciplinary research area with researchers from different disciplines such as LIS, human-computer interaction, psychology and sociology. We have concentrated our study to North America, Ireland, Great Britain and Scandinavia. In order to find researchers, we visited the websites of all universities with library and information science faculties in the chosen countries.

Svensk kunskapsorganisationsforskning 1990-2002

The purpose of this study is to characterize the research in the field of Knowledge Organization, during the period of 1990-2002, focusing on the subject and the epistemology of these studies. The result shows that studies concerning representation, e.g. subjects such as classification, indexing and bibliographic description, are the most frequently researched areas throughout the period. Classification was more popular in the beginning of the period, but later bibliographic description, mostly with studies on metadata, became more visible, together with a growing interest in information retrieval. The theoretical discussions in the studies focused primarily on document analysis and the organization of digital documents.

Ett gränssnitt blir till, design och implementation av ett grafiskt gränssnitt med inriktning interaktionsdesign och grafik

Gränssnitt finns överallt i vår vardag. Du finner dem i hemmet, i biblioteket, i affären, på tågstationen och till och med i din ficka. Hur kan utvecklingen av ett gränssnitt se ut och vad kan göras för att effektivisera utvecklingen? Ett gränssnitt kan alltid utvecklas och bli bättre. En gräns måste emellertid sättas för när gränssnittet är redo att komma ut på marknaden.

Säkerhet i öppna WiFi-nätverk. En studie om hur användares medvetenhet om säkerhetsrisker vid interaktion med öppna WiFi-nätverk kan ökas

Public WiFi networks is one of the dominant technologies for users to get public internet access. The problem is that the networks are designed for accessability rather than security ? a problem users seldom are aware of. Users who carelessly access WiFi networks may reveal sensitive information which, among other things, can lead to an identity theft. Previous research suggests that users must be educated and informed about the risks they incur, but not how this should be done.

Riktlinjer för mobil applikationsutveckling

Marknaden för mobila system har utvecklats enormt snabbt de senaste åren. Idag är det ett område med en allt större omsättning och det har vuxit fram som en helt ny gren inom Software Engineering. Utvecklare av mobila applikationer står ständigt inför en utmaning när det gäller att välja vilket mobilt system man ska satsa på när man utvecklar applikationer. Valet av system kan vara helt avgörande för om man hittar rätt målgrupp av konsumenter och därmed kan generera tillräckligt med omsättning för att driva lönsam utveckling av applikationer. Det räcker inte att enbart kolla på vilket system som har mest användare eller vilket system som genererar mest omsättning, utan man bör noggrant överväga de förhållande som gäller för just den applikation som ska utvecklas. Genom att följa denna guiden och överväga de olika faktorer som vi har sammanställt så kan man som utvecklare göra ett val som är baserat på aktuella marknadsundersökningar.

EU-patent på datorrelaterade uppfinningar : en rättsekonomisk analys

Computer programs must give a technical effect that goes beyond"normal physical interaction"to be considered to belong to a technical field. The invention shall be be susceptible of industrial application, which means that it should be possible to reproduce or use in any other industrial way. The reqirement that the invention shall be new means that the technique must not be previously known because of patents, published articles, etc. That an invention shall be a contribution to the state of the art in a technical field means that the invention shall not be obvious to invent for a person skilled in the art. Patents do effect the innovation among the inventers, but in most industries most inventions would be invented independent if there was a patent system or not.

Trafikinformation via SMS

Abstract The technology has made it possible for you as a train traveller to be available in other places than stations and on the train. You now have the possibility to communicate by the phone or through the Internet to get information about the train you want to take. Development in mobile technology gives us new possibilities to communication. We want to find out whatever SMS would be a suitable approach to inform passengers about delays. The problem formulation is ?If the technology is available to inform the passengers about delays in an more effective way than today, then why not use it? The ?Kustpilen? that operates in Blekinge and Skåne is the case for our study.

Södra Thailand: Civila samhället - roten till våldet?

Using Varshney's theory about intra- and interethnic networks, this thesis examines how civil society in southern Thailand is built up.During 2004 the violence between Muslims and Buddhists rose in southern Thailand. The government tried to fight the insurgency using violent police and military forces, resulting in hundreds of deaths and part of reason why Thailand is loosing rank in Freedom House's democracy index. Varshney means that a civil society built up on intraethnic networks works favourable to violence between different ethnic groups. Sorting out and defining what is meant by ?ethnic? and ?civil society?, this thesis shows why to look at the insurgency in southern Thailand as an ethnic conflict surviving partly because of an intraethnic civil society.
