Academic engineering graphics curricula are facing a rapidly changing knowledge base and current teaching and assessment methods are struggling to keep pace.  This paper is the second in a two-part series which examines practicing engineering graphics professionals to discover their…

The purpose of this study was to assess the pedagogical equivalence, as determined by knowledge gains, and the pedagogical effectiveness of certain components in a video-driven multimedia, web-based professional development training program as compared to a traditional, face-to-face program under…

The ethnobotany genomics concept is founded on the idea of 'assemblage' of biodiversity knowledge. This includes a coming together of different ways of knowing and valorizing species variation in a novel approach seeking to add value to both traditional knowledge…

Four different leaf extracts of B. microstachya var. massambabensis were studied to evaluate their antioxidant capacity by using three in vitro methods, with Ginkgo biloba and Trolox® as the standards. With the DPPH and ABTS·+ methods, the antioxidant activity of…

Current reasoning systems attempt to model an agent's knowledge and interaction with its environment in a symbolic manner. This environment, its world is generally dynamic and changing due to natural evolution or the actions of other agents that are a…

This study had three purposes: Firstly, to develop a categorization of research areas in distance education; secondly, to identify the most important research areas in distance education; and thirdly, to identify the most neglected research areas in distance education. Based…

Trypanosoma cruzi isolates from 23 acute chagasic patients from localities of Western Venezuela (state
of Barinas) where Chagas’ disease is endemic were typed using ribosomal and mini-exon gene markers.
Results showed that isolates of the two major phylogenetic lineages, T.…

Adult learners value the flexibility and convenience offered to them as online learners, and many learners are required to absent themselves from their online classes during courses in order to accommodate demanding schedules. What factors and tensions contribute to learners’…

In contrast with traditional academic disciplines, online educators do not have a generally accepted list of scholarly journals, which is in part a result of the multidisciplinary nature of the field, the relative infancy of online learning, and the view…

Pulp fibers’ bleaching technology has been developing mainly by applying increasingly intensive delignification in the cooking department and implementation of elemental-chlorine-free chemicals in the bleaching department. The resulting effluents load is still considerable, and the environmental consequences largely depend on…
