This paper presents a review of a sample of recent case studies on the use of asynchronous online discussion in higher education. These studies are analyzed in terms of curriculum design, assumptions about teaching and learning, and claims and reported conditions for using online discussion. The claims made for asynchronous online discussion—in particular the opportunities for interaction betwe...

The Implicit Relational Assessment Procedure (IRAP) examines implicit attitudes through the measurement of response latencies. In this study, the IRAP was used to assess implicit attitudes toward “mainstream” sexual terms (e.g., Kissing) and “BDSM” terms (e.g., Bondage) among individuals reporting BDSM interests and among students who did not report such interests. A questionnaire was used to m...

This paper is concerned with the stabilizability problem for discrete–time linear systems subject to a uniform quantization of the control set and to a regular state quantization, both fixed a priori. As it is well known, for quantized systems only weak (practical) stability properties can be achieved. Therefore, we focus on the existence and construction of quantized controllers capable of ste...

Optimizing communication with graduate medical trainees is critical, as they contribute importantly to the mission of academic medical centres. Yet, communication is challenged by their complex schedules, geographic separation, and time constraints. Few studies have examined this issue to offer valuable solutions. Because traditional approaches are suboptimal, two communication tools were imple...

This report discusses the implementation of an interpreter for a dialect of Scheme, written in Python. The language includes a simulated reflective tower, which is an abstraction allowing client code to pretend it is running on an infinitely deep stack of interpreters, where every interpreter interprets the interpreter above itself, ending with the client code on top of the tower. Every layer o...

Communication is important part of the education. Internet provides new and very effective forms of communication between students and teachers. This possibility positively influences the pedagogical process. It enables confrontation of ideas, exchange of materials and on-line communication on various projects. This contribution analyses the available communication tools and their utilization i...

Generic results regarding the structural properties of LTI singular system are presented in this paper. These include the structure of the system poles (both finite and infinite), assignment of the finite poles, elimination of the impulse mode, and controllability and observability of the closed-loop system. These properties are characterized by some new concepts defined in this paper.

This paper describes how the Prometheus Design Tool (PDT) is used to support the Prometheus methodology for designing agent systems. This is done by using an exemplar system that has been used previously in the literature, and is briefly described earlier in this volume. This paper presents the development of a design for this system using PDT. By using different tools and methodologies to desi...

BACKGROUND Surgery is a cornerstone of treatment for malignancy. However, significant variation has been reported in patterns and quality of cancer care for important health outcomes, including perioperative mortality. Surgical process improvement tools (SPITs) have been developed that focus on enhancing the processes of care at the point of care, as a means of quality improvement. This study d...

Focusing on applications for analyzing learner language which evaluate semantic appropriateness and accuracy, we collect data from a task which models some aspects of interaction, namely a picture description task (PDT). We parse responses to the PDT into dependency graphs with an an off-the-shelf parser, then use a decision tree to classify sentences into syntactic types and extract the logica...
