The development of the information and communications technology has enabled digital contents to be aggregated for better customer services. The purpose of this thesis is to investigate whether different types of content aggregators have different marketing strategies. In this research, content aggregators in Taiwan are divided into two categories. Their market positioning and market-mix strategies are compared. Six companies with different market positions were investigated and the result indicates that they are different in many of their marketing strategies, including the breadth and depth of product lines, pricing strategies, content delivery channels, and promotion. Suggestions for their future improvement are discussed.

The aim of the study is to learn more about the way preschool teachers work with Information and Communication Technology(ICT). More specifically, this study aims to explore how preschool teachers describe their experience of ICT, the conditions and opportunities to work with ICT, and their own knowledge and competence in the use of digital tools with preschool children. The research method consists of interviews with preschool teachers and observations at five municipal preschools in Stockholm as well as an analysis of the relevant passages in the Curriculum for the Preschool and the Curriculum of Stockholm city. This study shows that there seems to be great variation in the amount of ICT tools present in preschools. Preschool teachers expect a lot from ICT, and the improvements that it can make on their work. They express that the preschool has to meet the demands of an ever-developing society with respect to information and technology. They also recognize the importance of letting children use ICT tools, which are already familiar in the home environment. In the preschool, ICT is used as a part of the teacher-led activities and in theme work with the child group. Experience-based activities are also created with ICT tools. The rules and norms regulating ICT at the preschools include how the new devices, especially the tablets, should be used in preschool activities and what the mutual approaches at the preschools should be. These discussions are still active in this study and the preschool teachers seem to be looking for a quick fix, a simple manual that can lead them forward in their work with ICT.

Denna studie handlar om pojkars beskrivningar av att använda digitala spel och hur detta kan bidra till språklig kunskapsutveckling i skolans verksamhet. För att få studiens frågeställningar besvarade har intervjuer med fem pojkar i tio års ålder analyserats med utgångspunkt i socialsemiotiska teorier och begrepp. Pojkarnas beskrivningar visar tecken på att digitala spel kan användas som en resurs i utveckling av barns verbala och skriftligt språk. Pojkarna beskriver att utvecklingen av språklig och verbal kunskap kan äga rum dels individuellt och dels i grupp genom att använda digitala spel. Resultatet visar även att skolans verksamhet inte har erbjudit pojkarna möjlighet att använda digitala spel för att utveckla sina språkliga kunskaper.

Digital Forensics (DF) is defined as the ensemble of methods, tools and techniques used to collect, preserve and analyse digital data originating from any type of digital media involved in an incident with the purpose of extracting valid evidence for a court of law. DF investigations are usually performed as a response to a digital crime and, as such, they are termed Reactive Digital Forensic (RDF). An RDF investigation takes the traditional (or post-mortem) approach of investigating digital crimes after incidents have occurred. This involves identifying, preserving, collecting, analyzing, and generating the final report. Although RDF investigations are effective, they are faced with many challenges, especially when dealing with anti-forensic incidents, volatile data and event reconstruction. To tackle these challenges, Proactive Digital Forensic (PDF) is required. By being proactive, DF is prepared for incidents. In fact, the PDF investigation has the ability to proactively collect data, preserve it, detect suspicious events, analyze evidence and report an incident as it occurs. This dissertation focuses on the detection and analysis phase of the proactive investigation system, as it is the most expensive phase of the system. In addition, theories behind such systems will be discussed. Finally, implementation of the whole proactive system will be tested on a botnet use case (Zeus). / Graduate / 0984 / 0537 / soltanalharbi@hotmail.com
