Currently the challenges in e-Learning are converging the learning content from various sources and managing them within e-learning practices. Data mining learning algorithms can be used and the contents can be converged based on the Metadata of the objects. Ensemble methods use multiple learning algorithms and it can be used to converge the…

M-learning has enhanced the e-learning by making the learning process learner-centered. However, enforcing exam security in open environments where each student has his/her own mobile/tablet device connected to a Wi-Fi network through which it is further connected to the Internet can be one of the most challenging tasks. In such environments,…

This paper introduces a test sign-up application developed for a math department at a university. The requirements, design, and final software product are presented, along with one very important unexpected problem that arose after completion of the work--the system to be implemented and maintained by the client was not compatible with the…

The usability of Identity Management (IdM) systems is highly dependent upon design that simplifies the processes of identification, authentication, and authorization. Recent findings reveal two critical problems that degrade IdM usability: (1) unfeasible techniques for managing various digital identifiers, and (2) ambiguous security interfaces.…

The design of online learning environments is a complicated process because it entails the use of technological tools to mediate the various forms of interaction situated in the learning process. One possible way to help reduce such complication inherent in various forms of interaction is to look at design as a problem-solving activity. This means…

In engineering education, assessment instruments are often developed to evaluate programs and projects. Unfortunately, these innovations are not always adopted by intended audiences. Rogers' Diffusion of Innovations (DI) Theory provides a framework to analyze characteristics of an innovation that will affect adoption. The Appraisal System for…

In the quest for database usability, several applications enable users to design custom forms using a graphical interface, and forward engineer the forms into new databases. The path-breaking aspect of such applications is that users are completely shielded from the technicalities of database creation. Despite this innovation, the process of…

Teacher candidates have few opportunities during their teacher preparation coursework to investigate practices associated with eliciting and responding to student writing. This article describes an attempt to address this problem with a searchable online digital archive of student writing, with and without teachers' written feedback, as well…

PubMed® is an on-line literature database hosted by the U.S. National Library of Medicine. Containing over 21 million citations for biomedical literature--both abstracts and full text--in the areas of the life sciences, behavioral studies, chemistry, and bioengineering, PubMed® represents an important tool for researchers. PubMed® searches return…

Individuals in contact with the criminal justice system are a key population of concern to public health. Record linkage studies can be useful for studying health outcomes for this group, but the use of aliases complicates the process of linking records across databases. This study was undertaken to determine the impact of aliases on sensitivity…

An unprecedented amount of information encompassing almost every facet of human activities across the world is generated daily in the form of zeros and ones, and that is often the only form in which such information is recorded. A good fraction of this information needs to be preserved for periods of time ranging from a few years to centuries.…
