Many countries responded to the COVID-19 pandemic by implementing stay-at-home orders, curfews, and lockdowns which severely stifled economic activity. Retailers, in developed countries, used e-commerce to work around public health mandates, such as physical distancing; however, in developing countries, financial constraints and inadequate payment...

Many schools and institutions worldwide have integrated ICT competencies into their curricula because it is argued that ICT competence is necessary for economic development and social change. In developing nations such as the Caribbean, however, due to the digital divide, it is questionable whether citizens possess the ICT competencies necessary fo...

PowerPoint is a ubiquitous multimedia authoring tool that is widely used in education for in-class presentations and the distribution of course materials; however a common complaint is that it is linear and non-interactive thus does not enhance learning. Although the research literature describes methods of improving interactivity in PowerPoint suc...

It is expected that university students are competent, to some degree, in the use of productivity tools such as word processors, spreadsheets, presentation software and databases. The level of competency that most students possess in these productivity tools however is seldom reported in the literature. To determine these levels, a survey was admin...

Learning web publishing skills, specifically Extensible Hypertext Markup Language (XHTML), in a face-to-face classroom environment is difficult if predominated by chalk and talk instruction. This problem is exasperated further when the knowledge of the learners in the classroom vary. Learning XHTML on the Web appears to be a more effective practice...

An earlier study [1] examined the sophistication of e-tourism websites in Barbados and determined that although these websites were easy to use and provided some product/service information, they generally lacked company information, innovation in services, transaction processing and customer services. The earlier study assumed that since tourism w...

This paper describes a spectral-spatial model (for colour object recognition) which exploits the shape, colour and position of regions on the surface of a rigid object in describing it. Given a model and test image (with colour constancy pre-processing) suitably segmented into colour regions, model and test regions with similar shape and colour are...

In this paper a colour object search algorithm is presented. Given an image, areas of interest are generated (for each database model) by isolating regions whose colours are similar to model colours. Since the model may exist at one or more of these region locations, each is examined individually. At each region location the object size is estimate...

Many tourists search, book and pay for their accommodation through e-commerce websites using their credit cards. In developing countries like Barbados, however, although several of the small and medium-sized hospitality organisations (SMHOs) provide websites, many of them lack transaction processing capabilities (such as online payment) and custome...
