Content-centric networking (CCN) has emerged as a dominant paradigm for future Internet architecture design due to its efficient support for content dissemination, which currently dominates Internet use. This dissertation shows how economic and social welfare analysis can be used to inform the design of a CCN architecture that provides network…

The Open Biomedical Ontology (OBO) Foundry initiative is a collaborative effort for developing interoperable, science-based ontologies. The Basic Formal Ontology (BFO) serves as the upper ontology for the domain-level ontologies of OBO. BFO is an upper ontology of types as conceived by defenders of realism. Among the ontologies developed for OBO…

New products continue to launch quickly but many of them are converged products. The "new product" is not a completely new thing to consumers and the basic features stay the same. As a result, the added functions or fancy design can't explain why consumers adopt the new media. Past studies have examined perceptions of innovations or user…

This paper presents the usability evaluation of a digital systems laboratory class offered to distance-learning students. It details the way in which students can participate remotely in such a laboratory, the methodology employed in the usability assessment of the laboratory infrastructure (hardware and software), and also outlines the main…

Purpose: The purpose of this paper is to describe and discuss the use of specifically-developed, inquiry-based learning materials for Computing and Forensic Computing students. Small applications have been developed which require investigation in order to de-bug code, analyse data issues and discover "illegal" behaviour. The applications…

The cloud has become a widely used term in academia and the industry. Education has not remained unaware of this trend, and several educational solutions based on cloud technologies are already in place, especially for software as a service cloud. However, an evaluation of the educational potential of infrastructure and platform clouds has not…

The purpose of this thesis is to improve our understanding of sensemaking process as a basis for building better systems to assist sensemaking. Sensemaking is the task of creating an understanding of a problem or task so that further actions may be taken in an informed manner. Sensemaking is a pre-requisite for many other tasks such as decision…

This research investigated the impact of automated cognitive assistants, specifically, the Personalized Assistant that Learns (PAL), on situational awareness, efficiency and effectiveness of decision making in the brigade combat team. PAL was recently commissioned by Defense Advanced Research Projects Agency (DARPA) to enhance decision making with…

Purpose: The purpose of this paper is to analyze the usability of a remote learning system in its initial development phase, using a quantitative usability evaluation method through Markov models. Design/methodology/approach: The paper opted for an exploratory study. The data of interest of the research correspond to the possible accesses of users…

Information technology (IT) has the potential to improve the clinical learning environment. The extent to which IT enhances or detracts from healthcare professionals' role performance can be expected to affect both student learning and patient outcomes. This study evaluated nursing students' satisfaction with a novel compartmental Picture…

Purpose: The aim of this paper is to describe a project to provide an online web portal that can be used as a front-end for all university users--students, teachers, staff--and services, library, administration, e-learning, and e-mail. Design/methodology/approach: The profile model proposed is mainly inheritable, defined by profile components with…

Outlines the basic principles and research supporting the concept of narrative intelligence and its applicability to the ways in which people make sense of digital video. Explores relevant theory and research in sense-making, surrogates, narrative, and narrative intelligence and presents preliminary results of two research studies. Results have…

There is a common assumption that hypermedia navigation is influenced by a learner's style of thinking, so people who are inclined to apply sequential and analytical strategies (left-thinkers) are thought to browse hypermedia in a linear way, whereas those who prefer holistic and intuitive strategies (right-thinkers) tend towards non-linear paths.…

Presents an enriched video metadata framework including video authorization using the Video Annotation and Summarization Tool (VAST)-a video metadata authorization system that integrates both semantic and visual metadata-- metadata integration, and user level applications. Results demonstrated that the enriched metadata were seamlessly…

A text production model is considered as an instrument for researching the writing strategies of abstractors. Within this framework, abstracting is a subtype of the writer's activities, which are described in terms of text actions. A computer system can be constructed that evaluates and/or supports human text production. (Author/AEF)
