A mobile agent tool for resource discovery
2004
Publisher Summary This chapter discusses a mobile agent based tool for arranging communities whose members want to share computing resources. Such a tool enables community members to arrange their own parallel virtual machine, using resources available within the community. Mobile agents are used to search among available addresses inside the community, and are instructed to select the ones which correspond to the users' requirements. The agent is the key component of the system, because it takes care of the server availability test and of the decision on whether to include them into the virtual machine, according to the user's requirements. The database acts as an intermediary between the …
Role Scripting as a Tool to Foster Transactivity of Asynchronous Student Discussions
2021
Transactivity of student discussions is crucial in computer-supported collaborative learning (CSCL). However, CSCL learners often lack well-developed argumentation and negotiation skills, which makes it challenging for them to engage in and maintain a transactive discussion. Collaboration scripts have been implemented in CSCL contexts and have demonstrated positive effects on students' collaboration and argumentation skills. Yet, the degree of transactivity of student interactions is rarely addressed directly in CSCL research. Employing a qualitative content analysis approach, this study seeks to understand how a role script affects the transactivity of students' argumentative knowledge co-…
Scripting Computer-Supported Collaborative Learning
2010
In this chapter, we will present a review of theoretical and empirical analyses of Web-based collaboration processes used during a scripted university course. The results refer to a design-based study that involved first-year teacher-education students (N = 30) studying pedagogy over a period of three months. The intervention involved structuring the subjects’ collaborative actions with three different pedagogical scripts. According to the findings, the scripts guided students’ activities by helping them find resources for knowledge construction and work together through a series of steps. However, there were variations among groups in terms of quality of collaboration, and the students mos…
Security Implications of Using Third-Party Resources in the World Wide Web
2018
Modern web pages have nothing in common with the static connotation coming from the word “page” - it is a dynamic unique experience created by active content and executed within browser, just-in-time assembled from various resources hosted on many different domains. Active content increases attack surface naturally exposing users to many novel threats. A popular security advice has been to deploy active content blocker plugins like NoScript, unfortunately they are not capable to effectively stop the attacks. Content Security Policy (CSP) can be effective against these attacks, but we demonstrate how poor decisions made by website administrators or external resource hosters can render CSP in…

Creating context as you go
2009
In this paper, we discuss how a short-range wireless communication scheme called Mobile Encounter Network (MEN) can provide additional value for both the consumer and the service/product provider (the company). When used as an information search system on the market environment, a MEN-based system allows services and products being promoted at the location they are available. From the customer's point of view, MEN may provide a "digitally augmented vision", an enhanced view to the current environment. Combined with a set of filtering and search rules this may provide a self-manageable context combining the user's own personal environment and preferences to the services and features availabl…
From information to conversation
2000
We support the calls from many commentators to include human interaction in the web, rather than as an extra outside the web. We suggest a generic model of awareness, and some specific interpretations: action-event couplings to call a receiver; general awareness of known others; and local awareness of all others. We then consider extensions to the web into mobile and domestic appliances, and suggest that an underlying awareness service will be needed there as much, or more than in classic desktop web access.
Building a Medical Research Cloud in the EASI-CLOUDS Project
2014
The demand for IT resources is constantly growing in the scientific area. The ability to store and process increasing amounts of data has transformed many research disciplines, like the life-sciences, which now rely on complex data processing and data analytics. Cloud environments are able to integrate and encapsulate possibly distributed resources and allow convenient and on-demand access to the corresponding services, tools, and complete work environments. The European research project EASI-CLOUDS (http://www. easi-clouds.eu) develops a platform for a convenient service delivery with special regard to service integration, monitoring, management, and Service Level Agreement (SLA) negotiati…
Foto2Events: From Photos to Event Discovery and Linking in Online Social Networks
2014
International audience; — Online social networking has become the predominant activity in the digital world thanks to multimedia data (mainly photos) sharing (e.g., photos now represent 93% of the top posts on Facebook). Discovering events where users are involved using their own posts and those shared by their friends would be of great importance. In this paper, we address this issue by providing an original approach able to detect, enrich and also link user's events using photos shared within his online social networks. Using metadata, our approach provides a multi-dimensional gathering of similar photos using their temporal, geographical, and social facets. To validate our approach, we i…
