Educational Magic Tricks Based on Error-Detection Schemes
Magic tricks based on computer science concepts help grab student attention and can motivate them to delve more deeply. Error detection ideas long used by computer scientists provide a rich basis for working magic; probably the most well known trick of this type is one included in the CS Unplugged activities. This paper shows that much more powerful variations of the trick can be performed, some in an unplugged environment and some with computer assistance. Some of the tricks also show off additional concepts in computer science and discrete mathematics
Optimizing Anti-Phishing Solutions Based on User Awareness, Education and the Use of the Latest Web Security Solutions
Phishing has grown significantly in volume over the time, becoming the most usual web threat today. The present economic crisis is an added argument for the great increase in number of attempts to cheat internet users, both businesses and private ones. The present research is aimed at helping the IT environment get a more precise view over the phishing attacks in Romania; in order to achieve this goal we have designed an application able to retrieve and interpret phishing related data from five other trusted web sources and compile them into a meaningful and more targeted report. As a conclusion, besides making available regular reports, we underline the need for a higher degree of awareness related to this issue.Security, Phishing, Ev-SSL, Security Solutions
An e-learning platform for delivering educational contents in a school environment
Learning is a continuous process, without end, which takes place throughout life, and is the result of the interaction of an individual with a physical external environment, a social context or with herself. In what new technologies may help improving and making more effective the interaction of an individual during his learning process? This paper describes the use of a platform for delivering educational contents to students, to put theories into practice through the use of an LMS and highlight the strengths and weaknesses that have these learning tools in a school environment, in which - besides its formative aspect - upbringing is important.learning management system, digital contents.
HDR video past, present and future : a perspective
High Dynamic Range (HDR) video has emerged from research labs around the world and entered the realm of consumer electronics. The dynamic range that a human can see in a scene with minimal eye adaption (approximately 1,000,000: 1) is vastly greater than traditional imaging technology which can only capture about 8 f-stops (256: 1). HDR technology, on the other hand, has the potential to capture the full range of light in a scene; even more than a human eye can see. This paper examines the field of HDR video from capture to display; past, present and future. In particular the paper looks beyond the current marketing hype around HDR, to show how HDR video in the future can and, indeed, should bring about a step change in imaging, analogous to the change from black and white to colour
Reducing the risk of e-mail phishing in the state of Qatar through an effective awareness framework
In recent years, cyber crime has focused intensely on people to bypass existing sophisticated security controls; phishing is one of the most common forms of such attack. This research highlights the problem of e-mail phishing. A lot of previous research demonstrated the danger of phishing and its considerable consequences. Since users behaviour is unpredictable, there is no reliable technological protective solution (e.g. spam filters, anti-viruses) to diminish the risk arising from inappropriate user decisions.
Therefore, this research attempts to reduce the risk of e-mail phishing through awareness and education. It underlines the problem of e-mail phishing in the State of Qatar, one of world s fastest developing countries and seeks to provide a solution to enhance people s awareness of e-mail phishing by developing an effective awareness and educational framework. The framework consists of valuable recommendations for the Qatar government, citizens and organisations responsible for ensuring information security along with an educational agenda to train them how to identify and avoid phishing attempts. The educational agenda supports users in making better trust decisions to avoid phishing that could complement any technical solutions. It comprises a collection of training methods: conceptual, embedded, e-learning and learning programmes which include a television show and a learning session with a variety of teaching components such as a game, quizzes, posters, cartoons and a presentation. The components were tested by trial in two Qatari schools and evaluated by experts and a representative sample of Qatari citizens.
Furthermore, the research proves the existence and extent of the e-mail phishing problem in Qatar in comparison with the UK where people were found to be less vulnerable and more aware. It was discovered that Qatar is an attractive place for phishers and that a lack of awareness and e-law made Qatar more vulnerable to the phishing. The research identifies the factors which make Qatari citizens susceptible to e-mail phishing attacks such as cultural, country-specific factors, interests and beliefs, religion effect and personal characteristics and this identified the need for enhancing Qatari s level of awareness on phishing threat.
Since literature on phishing in Qatar is sparse, empirical and non-empirical studies involved a variety of surveys, interviews and experiments.
The research successfully achieved its aim and objectives and is now being considered by the Qatari Government
Raising public awareness of mathematics
This book arose from the presentations given at the international workshop held in Ăbidos, 26â29 September 2010, as a result of a joint initiative of the Centro Internacional de MatemĂĄtica and the Raising Public Awareness (RPA) committee of the European Mathematical Society (EMS). The objective was to provide a forum for general reflection with an international mix of experts on building the image of mathematics, ten years after the World Mathematical Year 2000 (WMY 2000). Ăbidos, a charming town situated one hour by car to the north of Lisbon, Portugal, was also the site of the re-creation in the year 2000 of the international mathematics exhibition âBeyond the Third Dimensionâ (http://alem3d.obidos.org/en/) and a meeting of the EMS WMY2000 Committee. The opening of the workshop was also a public âmathematical afternoonâ organised by the Portuguese Mathematical Society (SPM) in cooperation with the town of Ăbidos. At this event mathematical films and lectures to the general public were presented. The first lecture was given by H. LeitĂŁo, from the University of Lisbon, on mathematics in the âAge of Discoveriesâ, and the second one by G.-M. Greuel, the current president of ERCOM (the EMS committee of the European Research Centres on Mathematics), on the topic âMathematics between Research, Application and Communicationâ, which text is included in this book.info:eu-repo/semantics/publishedVersio

The impact of emotions on student participation in an assessed, online, collaborative activity
There is growing recognition of the importance of emotions in academic online learning contexts. However, there is still little known about the role of emotions in social and collaborative online learning settings, especially the relationship between emotions and student participation. To explore this relationship, this study used a prospective longitudinal research design to follow 46 distance learning students throughout a 3-week assessed, online, collaborative activity. This approach allowed the fluctuating and dynamic aspects of emotions to be explored as well as the relationship between emotions and student participation in the collaborative activity. Self-report data were gathered using a semistructured online diary at five time points throughout the task (once at the start of the collaborative activity, three times during the activity, and the final entry after the activity had finished). Findings revealed that learners generally perceived pleasant emotions (such as relief, satisfaction and enjoyment) to have positive impacts, or no impact, on participation, whereas unpleasant emotions (such as anxiety, frustration, and disappointment) were generally perceived to have negative impacts, or no impact, on participation. Interestingly, however, anxiety, and to a smaller extent frustration, were perceived by a number of students to have positive impacts during the activity. To conclude this paper, implications for educators are highlighted
SELF-IMAGE MULTIMEDIA TECHNOLOGIES FOR FEEDFORWARD OBSERVATIONAL LEARNING
This dissertation investigates the development and use of self-images in augmented reality systems for learning and learning-based activities. This work focuses on self- modeling, a particular form of learning, actively employed in various settings for therapy or teaching. In particular, this work aims to develop novel multimedia systems to support the display and rendering of augmented self-images. It aims to use interactivity (via games) as a means of obtaining imagery for use in creating augmented self-images. Two multimedia systems are developed, discussed and analyzed. The proposed systems are validated in terms of their technical innovation and their clinical efficacy in delivering behavioral interventions for young children on the autism spectrum
