Organizational computing tools are often developed and managed with an eye toward increasing efficiency. Two of today’s most widespread tools are electronic mail and voice mail. They are often considered similar asynchronous communication systems, one less rich than the other. We report usage results from a single firm which adopted both electronic mail and voice mail at the same time. Survey r...

As a broader array of communication tools is developed, designers of learning environments need a better understanding of what kinds of communication each medium is best suited for. Each of the new media have different affordances and constraints. One of our principles for the design of learning environments is “Render unto each medium what it does best.” This paper is an attempt to state some ...

The purpose of this study was to investigate the effect of using synchronous and asynchronous communication tools in online group activities to develop collaborative learning skills. An experimental study was implemented on a sample of faculty of education students in Mansoura University. The sample was divided into two groups, a group studied using synchronous communication tools, and the othe...

Aiming to offer a framework for blended learning to the teaching of proof theory, the present paper describes an interactive tutorial, called TryLogic, teaching how to solve logical conjectures either by proofs or refutations. The paper also describes the integration of our infrastructure with the Virtual Learning Environment Moodle through the IMS Learning Tools Interoperability specification,...

In this paper we present a platform (electronic environment) which has been developed to support activities of hybrid learning, as well as of hybrid psychology. The electronic environment supports synchronous and asynchronous activities of teaching and learning via communicative and informative tools and services. These “tools and services”, are constructed in a powerful modular environment whi...

Legal doctrine starts to speak of Inter-systemic electronic contracting, where an important role is played by soft bots, i.e., intelligent software agents, which may be fiction as tools controlled by humans or faced as subjects of electronic commerce, or even seen as legal objects or as legal subjects. The use of software agents in electronic commerce scenarios must be connected with the existe...

The Internet and the proliferation of inexpensive computing power in the form of clusters of workstations or PCs provide the basic hardware infrastructure for business to business electronic commerce in small and medium enterprises. Unfortunately, the corresponding software infrastructure is still missing. In this paper we show a way to develop appropriate tools for electronic commerce by descr...

In this paper, we investigate the robust stability problem of a class of LTI discrete uncertain singularly perturbed time-delay systems. If the singular perturbation parameter of these systems is sufficiently small, they can be separated into two reduced-order subsystems, the slow subsystem and fast subsystem. Two stability criteria for the slow and fast subsystem of the uncertain system are th...

background: the spread of technology has influenced different aspects of human life, and teaching and learning are not exceptions. this study aimed to examine the potential contribution of the use of technology in teaching english language to medical students.   methods: this qualitative-action research study was conducted in birjand university of medical sciences (bums), with 60 medical studen...
