Graph representations underlie many modern computer applications, capturing the structure of such diverse networks as the Internet, personal associations, roads, sensors, and metabolic pathways. While the static structure of graphs is a well-explored field, a new emphasis is being placed on understanding and representing the way these networks…

While many institutions deliver some classes in blended format, Brandman University transitioned all of its face-to-face classes to blended delivery, using a model tailored to the needs of adult learners. This article provides research supporting the ways that blended learning principles align with key principles of andragogy. The article provides…

This article describes a parallel and distributed processing model (PDPM) of joint attention, self-referenced processing and autism. According to this model, autism involves early impairments in the capacity for rapid, integrated processing of self-referenced (proprioceptive and interoceptive) and other-referenced (exteroceptive) information.…

The framework for the study of concept formation embraced by the articles in this special issue makes it possible to observe and catalog the mechanisms by which conceptual structures in the wild achieve and maintain organization. I propose a provisional inventory of such mechanisms that includes the primitive mechanisms of dimensionality…

In the information systems field there are numerous programming languages that can be used in specifying the behavior of concurrent and distributed systems. In the literature it has been argued that a lack of pragmatic and semantic consideration decreases the effectiveness of such specifications. In other words, to simply understand the syntactic…

Increasing complexity and sophistication of ever evolving information technologies has spurred unique and unprecedented challenges for organizations to protect their information assets. Companies suffer significant financial and reputational damage due to ineffective information technology security management, which has extensively been shown to…

An E-learning system based on a multi-agent (MAS) architecture combined with the Dynamic Content Manager (DCM) model of E-learning, is presented. We discuss the benefits of using such a multi-agent architecture. Finally, the MAS architecture is compared with a pure service-oriented architecture (SOA). This MAS architecture may also be used within…

Findings from this study show that educational and mobility opportunities for families and students participating in the Chilean voucher system are not homogenously distributed. Some families and students use and benefit from the system, while others will remain marginalized. The quantitative results in this study demonstrate that students of…

MINDS (Multiple Intelligent Node Document Servers) is a distributed system of knowledge-based query engines for efficiently retrieving multimedia documents in an office environment of distributed workstations. By learning document distribution patterns and user interests and preferences during system usage, it customizes document retrievals for…

LYDIAN is an environment to support the teaching and learning of distributed algorithms. It provides a collection of distributed algorithms as well as continuous animations. Users can combine algorithms and animations with arbitrary network structures defining the interconnection and behavior of the distributed algorithm. Further, it facilitates…

In large-scale educational reforms, many actors play their roles. The diversity of contributions and lack of harmonization prove to be frequently found to cause educational reform failures. Many explanations for these failures focus on differences between the actors and on differences in their contributions to the reform process. In this article,…

Discusses software engineering and suggests necessary elements in a software engineering curriculum. Topics addressed include the importance of theory, project-oriented education, prototyping, exploratory programing, human-computer communication, thought models, distributed systems, parallel processing, documentation, testing and quality…

Discusses instructional delivery models and their physiology in distributed learning systems. Highlights include building delivery models; types of delivery models, including distributed classroom, self-training on the Web, online training, communities of practice, and performance support systems; and actors (users) involved, including experts,…
