E-Learning is not almighty, nor can it teach everything. On the other hand, e-Learning is very suitable for playing such auxiliary roles as help teachers estimate the effectiveness of their lessons or help students know the current status of their abilities. This paper presents an easy, enjoyable, effective automated practice and test system, which teachers can easily administer, and with which...

There has been a great deal of hype surrounding the introduction of e-Learning tools and applications within higher education both in the UK and internationally. Although e-Learning has come a long way in recent years it has yet to gain a firm foothold in many areas of education and its use within Higher Education in the UK is fragmented to say the least. The pros and cons of e-Learning are not...

In this paper, the phenomenon of electronic retailing is examined. Elements that make e-tailing especially attractive to consumers are highlighted. It is argued that traditional retailers have to critically consider the migration to a digital domain, and address challenges that might impede a smooth transition. Conversely, e-tailers have much to learn from their counterparts in the physical wor...

Over the past years, we have witnessed a fundamental economic transformation. Economists generally acknowledge that a profound shift has occurred in the role that knowledge and technology play in driving productivity and economic growth (Stiglitze, 1999 cited from Kozma, 2003), a phenomenon referred to as the “Knowledge economy.” These changes entail new skills, abilities, attitudes, and habits...

This research investigates whether information technologies, such as automated question answering (QA), can add interactivity into a multimedia-based e-learning system, as well as how this type of virtual interaction affects the effectiveness of e-learning. Based on a review of multiple learning theories and technologies, an exploratory model for studying the effectiveness of interactive e-lear...

BACKGROUND Electronic nicotine delivery systems (ENDS; commonly known as electronic cigarettes or e-cigarettes) have been commercially available in the United States since 2007, yet recently have generated substantial controversy as their use and availability expands. ENDS are battery-operated devices designed to resemble traditional cigarettes that heat and vaporize nicotinecontaining solution...

A bstract We consider higher-dimensional effective (EFT) operators consisting of fermion dark matter (DM) connecting to Standard Model (SM) leptons upto dimension six. Considering all together and assuming the DM undergo thermal freeze-out, we find out relic density allowed parameter space in terms mass ( m χ ) New Physics (NP) scale (Λ) with one loop direct search constraints from XENON1T expe...
