XML databases are widely used in many different areas. They are multi user systems and can store a huge amount of data. Sensitive and important data need to be protected and stored securely. We have developed a dynamic trust based access control for XML databases to improve the security level and prevent malicious transactions from both internal and external users. Our system tracks user history of...
This paper presents study investigating the extent to which Saudi students understand and are familiar with mobile learning. It investigates students' use of handheld devices and considers the daily activities for which they could be used while also evaluating m-learning in Saudi Arabia - a topic that has not yet received adequate attention from researchers. Initial data was acquired through a questionnaire...
Learning requires appropriate management of time and resources. Consequently, self regulated learning (SRL) becomes predominant and apparent (Bartolome et al., 2011; Lefrere, 2011). More and more educators at all educational levels are trying to enfold self regulated learning in the learning process (van Ewijk et al., 2012; Kramarski et al., 2009). The use of technology-based procedures transforms...
Nowadays, when more than half of the world's population lives in urban areas, when information and (mobile) communication technologies are real catalysts for innovations in all domains, there are a lot of studies and debates related to how our cities should become “Smart Cities”, “Smarter Cities” or “Future Cities”, in order to improve life quality and to reduce costs, to become a “Smart Learning...
While innovative e-Health and m-Health technologies and solutions will eventually change the way health and social care are delivered, it raises many challenges regarding what sort of ethical concerns need to be addressed in order to provide imperative regulations and guidance to healthcare professionals and developers. This paper discusses key ethical challenges identified as part of an ongoing research...
At present, countries around the world attach great importance to college students' employment. The employment of university graduates has also been a focus of social attention. Playing the advantages of university students hunting for a job on the Internet, on constructing and developing online self-employment service and employment information service and improving the employment information degree...
In recent years, social networking system has become one of the most popular Internet applications and has a large number of users. Although the public social networking systems have meet the interpersonal communication demand of people, there is inadequate support for the closely combination of user's learning, working and cultural life on campus with their real activity. Therefore, the paper design...
Analysis and mining of social media has become an important research area. A challenging problem in this area consists in the identification of a group of users with similar patterns. In this paper, we propose the classification of users based on their activity profiles (e.g., periods of the day when the user is most and least active in online communications). Activity profiles can be useful for many...
At the time when we are debating the Internet as a human right, an access to basic online information is a challenge for blind and visually impaired community. Steps taken for their digital inclusion, such as, the Web Content Accessibility Guidelines (WCAG) are often insufficient. In this paper we present initial requirements gathered during three workshops organized with various stakeholders coming...
After the survey was conducted two years ago in this particular school, I determined certain difficulties regarding usage of Facebook among our students. During the last two years I addressed the problem and begun giving social networking lectures to students, their parents and teachers, later I have incorporated social network workshops in curriculum and especially emphasized the importance of Netiquette...
Since participatory sensing relies on users' active participation, several monetary incentive mechanisms for attracting users' participation have been proposed. However, to make users participate in “heavy” sensing tasks (either physically or mentally), stronger incentive is required. Thus, the total amount of rewards paid by the client will quickly rise. In this paper, we propose a novel incentive...
In this work, we propose haptic-based bilateral tele-operation for quad-rotor vehicles by using Internet communication infrastructure. The idea is to introduce shared autonomy to increase remote operation and manipulation capacity of the vehicle in uncertain flying environments. The design couples ground and remote sites by position and velocity signals of the master haptic and slave quad-rotor vehicle...
Previous work within health communication has been concerned with how to tailor intervention content in a way that is most effective in supporting the individual in changing health behaviors such as smoking, physical activity or diet. This kind of tailoring is based on data gathered from the user through questionnaires with textual feedback adapted by algorithms pre-specified according to behavioral...
Internet of Things (IoT) services and technologies become more and more predominant in the current and future era of the Internet. Lot of devices and applications are developed and connected to the classical IP networks. As for any new network services testing and evaluation is made in the intranet environment in these days. Neither the efficiency measurement methods of the energy usage nor communication...
How to embed more secret message into web page with keeping good imperceptibility simultaneously is a trade-off problem for information hiding schemes. This paper presents a novel web page information hiding method based on three inherent features of current web page's HTML Code matrix. This method firstly exploits chaotic transform to deal with secret message, then embeds each bit of secret message...
This quantitative study explores students' motivation towards the use of wikis to encourage self-directed learning (SDL) and collaborative learning (CoL). SDL and CoL are the goals for Singapore's Ministry of Education Information and Communication Technology Masterplan 3. Wikis were used in the project to support reflection and communication within groups. Five classes consisting of 181 Secondary...
This paper takes the form of a combined narrative of the school principal and the dean of development, research and technology on their reflection of the school's efforts in the integration and pervasive use of technology for teaching and learning. The main intent of this paper is to put in writing the tacit knowledge and insights — the expansive cycles that we have experienced (Engeström, 2001) and...
Global Engineering is the last frontier in education. It creates a dilemma of providing engineering education anywhere in the World, preserving local cultural values, and applying it anywhere around the Globe. A recent Singapore Declaration [ASEE Global Forum, 2009], and consecutive World Engineering Education Forums, [1] paved the roadmap towards Global Engineering calling for practical solutions...
