The graduate thesis presents an analysis of the Web 2.0 applications developement. It defines the preliminary conditions and describes the technologies used for the creation of these applications, such as the markup languages HTML and XML, style sheet language CSS, tranfortmations language XSLT and scripting language JavaScript. The thesis depicts the security risks and the ways how the application can be protected against the XSS attacks and SQL Injection. Furthermore, it analyses a concept of the system containing features of the Web 2.0 trend, and its implementation in practice. The internet portal enabling all registered users to share information with the others, will be the result. Files can be uploaded, and maps and videos can be inserted into the system.

The use of Facebook is increasing rapidly and its pedagogical uses are endless. University students are part of a new generation, working with ease and confidence in this social environment. This article explores the use of Facebook as an additional communication tool in an undergraduate taxation module presented at the University of Pretoria and evaluates students’ perceptions of the effectiveness of such a tool. A Facebook group was created to enhance interaction between students and lecturers and students and their peers. Participation was voluntary, and the students completed a survey at the end of the semester to evaluate their experience in the group. The results of the study show that, although the use of a Facebook group as a communication tool cannot replace the formal learning management system of the university, respondents’ perception of the use of the tool was that Facebook could be used as an additional academic communication tool in all of their subjects. It is the lecturers’ responsibility to learn how to use this tool and incorporate it effectively into their teaching strategies. Copyright 2012, University of Pretoria. All rights reserved.

Die vorliegende Arbeit gibt einen Überblick über die Häufigkeit und Qualität des Einsatzes des Internets in sächsischen Gymnasien aus der Sicht der Lehrerinnen und der Lehrer. In dieser Untersuchung wurde jedoch belegt, dass die Gymnasiallehrkräfte in Sachsen das Internet selten in ihrem Unterricht einbinden. Außerdem erstrecken sich die Nutzungsformen von der Recherche im WWW bis zur Nutzung der Übungs- und Lernprogramme sowie auf das Suchen nach aktuellen Arbeitsmaterialien. Mit der schulischen Internetnutzung verbinden die sächsischen Gymnasiallehrer verschiedene pädagogische sowie didaktische Ziele. Die Hinderungsgründe, die den Einsatz des Internets in der Schule hemmen, sind ganz unterschiedlich, von methodisch-didaktischen Problemen bis meistens, den technischen Problemen und Jugendschutzproblemen. Als soziodemographische Einfluss- faktoren spielen das Alter und das Geschlecht eine Rolle bei der schulischen Internetnutzung. Darüber hinaus üben die Eltern- und Schülererwartungen an einem Interneteinsatz in der Schule, die Einstellung der Lehrer zur Internetnutzung in der Schule, die Bedenken hinsichtlich der Internetnutzung im Unterricht sowie ihre jeweilige subjektive Einschätzung ihrer Internet-kompetenz einen Einfluss aus. Tatsächlich scheinen die sächsischen Gymnasiallehrer für die Integration der Neuen Medien (Computer und Internet) gut gerüstet. Schließlich reiht sich das neue Medium „Internet“ mit der Zeit in die Liga der klassischen Medien ein und wird seine Stellung in der Schule als Lehr- und Lernmedium für den Unterricht in Zukunft wohl noch weiter ausbauen.

Entwicklung von AJAX - Was ist Web 2.0 / Social Web? - Anwendungen im Web die AJAX nutzen

There is little in the existing literature that provides practical information on the link between co-creation and the internet as well as guidance on how to facilitate cocreation in the online environment. This study sought to address these gaps and particularly the lack of guidance on the practical act of co-creation and the relationship between co-creation and the online environment. A quantitative research methodology with a descriptive design was followed. The data for the study was collected by way of an internet survey. The population for the research was defined as the users of the online cycling social network, www.thehubsa.co.za. A topic explaining the purpose of the study and inviting users to participate was posted on the website. The study revealed the existence of a new two factor solution related to the separate co-creation and Web 2.0 applications constructs. In this respect the Interact and Use components (co-creation) as well as the Creating and Sharing components (Web 2.0 applications) could provide the foundation for construct validity for more comprehensive scales.The ability of a user to Author content on a website was found to be of particular practical importance in facilitating co-creation. Providing this functionality to a customer may be the key to the missing “how to” element of online co-creation. The ability of a social networking website, such as www.thehubsa.co.za, to encourage general product/service usage appears to be the main attraction to advertisers. Advertisers looking to build their brands may not necessarily obtain the same benefits from the website. Findings regarding impact on usage were inconclusive and further research is suggested.

For nearly sixty years, scholars have studied how information is selected, vetted, and shared by news organizations. The process, known as gatekeeping, is an enduring mass communications theory that describes the process by which news is gathered and filtered to audiences. It has been suggested, however, that in the wake of online communications the traditional function of media gatekeeping is changing. The infusion of citizen-gathered media into news programming is resulting in what some call a paradigm shift. As mainstream news outlets adopt and encourage public participation, it is important that researchers have a greater understanding of the theoretical implications related to participatory media and gatekeeping. This study will be among the first to examine the adoption of citizen journalism by a major cable news network. It will focus on CNN's citizen journalism online news community called iReport, which allows the public to share and submit "unfiltered" content. Vetted submissions that are deemed newsworthy can then be broadcasted across CNN's networks, and published on CNN.com. This journalism practice appears to follow the thoughts of Nguyen (2006), who states that, "future journalists will need to be trained to not only become critical gate-keepers but also act as listeners, discussion and forum leaders/mediators in an intimate interaction with their audiences." The goal of the paper is to lay a foundation for understanding how participatory media is utilized by a news network to help researchers possibly develop new models and hypotheses related to gatekeeping theory.

This thesis is devoted to blogs and their commercialization, a phenomenon of the on-line world for last few years. The aim of this work is to explore several Czech lifestyle blogs and to find out how much commercial content there is, also how the audience reacts to this content as well as how the bloggers themselves approach commercial content. In the beginning the development of blogs is described, both in the Czech and global environment. The characteristic features of blogs from different perspectives on the issues are also described. The development of blogs is then set in the context of events that made it possible at all. Furthermore, attention is paid also to the process of commercialization of content on the blogs and the possibilities monetizing the blogs' content. Emphasis is placed primarily on a detailed description of influencer marketing and its current situation, but it also discusses affiliate marketing and the use of public relations tools on blogs. The research part provides an insight into the issue of Czech blogs and the current blogosphere. First the chosen blogs are described and set in the context of the Czech blogosphere, then, based on a detailed content analysis, the level of commercial content on the selected blogs is described as well as how the audience reacts to it....

The rise of social media has challenged the traditional notionof CRM and introduced a new paradigm, known as socialCRM. While there are many benefits and opportunitiesassociated with the integration of social data in CRMsystems, a majority of companies are failing their social CRMimplementation. Since social CRM is still considered to be ayoung phenomenon, knowledge regarding itsimplementation and functionalities is limited. The purpose ofthis study is to contribute to the current state of knowledgeregarding the factors which influence the practicalimplementation of social CRM. In order to capturestate-of-the-art knowledge on this topic, a literature reviewwas conducted. In addition, interviews with CRM expertsworking within five Swedish companies were included inorder to gain additional insights from practice. Findingsindicate that the key features needed for social CRMimplementation revolve around the real-time monitoring,collection, processing, storing and analyzing of social data.Advanced technical tools, such as Big Data Technology, aredeemed required in order to handle large volumes of dataand properly transform it into valuable knowledge. The mostsignificant challenges identified heavily revolve aroundlimited knowledge as well as various technical andorganizational limitations. Additionally, findings indicatethat a multitude of uncertainties of practitioners revolvearound data legislations and privacy concerns. Hence, whilesocial CRM can entail a multitude of benefits, there are asignificant number of challenges which seem to stand in theway of unlocking the full potential of social CRM. In orderfor social CRM implementation to be made more accessiblefor organizations in the future, there is a need for moreknowledge and clarity regarding factors such as technicalsolutions, organizational changes and legislations.

This master’s thesis project concerns implementing and evaluating Web 2.0 services for IPTV. This thesis project was carried out at Accedo Broadband during the period August to December 2008. Accedo Broadband is a provider of interactive applications and on-demand content for IPTV. The report will analyze, specify, create, and evaluate a solution for adding Web 2.0 functionality from the most popular sites as IPTV content. We will evaluate several different web services APIs and examine how suitable they are for implementation in the context of IPTV. An IPTV set-top box has limited CPU processing power, memory capacity, screen resolution is generally limited to 720 by 576 pixels, and only a limited set of input devices and interfaces are available. The IPTV set-top box receives digitally encoded audio and video content through IP and renders this content so it is viewable on an analogue TV and the audio is output via speakers. The goal of this project is to reduce the amount of integration work and configuration necessary for creating Web 2.0 IPTV applications by creating a general framework for Web 2.0 applications. We will present and evaluate the most common web programming technologies and see which are most suitable for our purposes. We have developed four different interactive demonstration services to illustrate the usage of an IPTV platform. / Denna rapport är ett examensarbete beträffande implementering och evaluering av Webb 2.0 tjänster för IPTV. Examensarbetet har utförts på företaget Accedo Broadband under perioden augusti till december 2008. Accedo Broadband är ett företag som utvecklar interaktiva applikationer och on-demand tjänster för IPTV. Denna rapport handlar om att analysera, specificera, skapa och utvärdera en lösning för att kunna implementera en Webb 2.0 funktionalitet från de mest populära tjänsterna till IPTV. Vi utvärderar olika webbtjänsters API:er och utforska hur passande dom är. En IPTV set-up box har begränsad CPU, minne, skärmstorlek på 720×576 pixlar och en begränsad uppsättning av inmatningenheter &amp; gränssnitt. IPTV set-top boxen tar emot digitalt kodade ljud- och videoströmmar genom IP och konverterar dem så att det går att se på en analog TV. Målet med detta projekt är reducera arbetet med integrationen och nödvändiga konfigurationer för IPTV för Webb 2.0 applikationer. Vi kommer att presentera och utvärdera den webbteknik som är vanligast förekommande och ser vilka som passar våra syften bäst. Vi har utvecklat fyra olika demonstrations applikationer för att illustrera hur en IPTV plattform fungerar.

The existing advanced web browsers in today’s mobile phones open up the door for mobile web applications. By using standard webtechnologies, a web page can be crafted to mimic the behavior of a normal application. The purpose of this master’s thesis has been to look at web application development for mobile phones in general and to implement a web-based Mobile TV client to determine whether it would be a viable alternative to existing clients based on other technologies. The advantages are the same as for any other web application: 1) the user avoids the hassle of installing an application and will always run the latest version, 2) developers benefit from the browser’s ability to render generic content, and 3) it is believed that the differences between browser implementations are less than in other environments in which an application would run, for example Java or operating system specificenvironments. / De avancerade webbläsare som redan idag finns tillgängliga på nyare mobiltelefoner har gjort det möjligt att skapa mobila webbapplikationer. Genom användandet av befintlig webbteknik kan en webbsida utformas på ett sådant sätt att den uppträder som en vanlig applikation. Syftet med det här examensarbetet har varit att titta på webbutveckling för mobiltelefoner i allmänhet samt att implementera en webbaserad MobilTV-klient för att avgöra hurivida en sådan lösning skulle kunna utgöra ett alternativ till redan existerande klienter baserade på andra teknologier. Fördelarna antas vara desamma som för andra webbapplikationer: 1) användaren slipper installera ett program och kommer alltid att köra den senaste versionen, 2) utvecklingen gynnas av webbläsarens förmåga att rendera godtyckligt innehåll och 3) skillnaderna mellan olika webbläsarimplementationer anses vara mindre i jämförelse med andra miljöer i vilka en applikation körs, till exempel Java- eller operativsystemspecifika.
