In this paper we explore how to import intelligent support for group learning that has been demonstrated as effective in classroom instruction into a Massive Open Online Course (MOOC) context. The Bazaar agent architecture paired with an innovative Lobby tool to enable coordination for synchronous reflection exercises provides a technical foundation for our work. We describe lessons learned, di...

Using numerical simulations, here, we demonstrate that a single sheet of graphene with properly designed inhomogeneous, nonuniform conductivity distributions can act as a convex lens for focusing and collimating the transverse-magnetic (TM) surface plasmon polariton (SPP) surface waves propagating along the graphene. Consequently, we show that the graphene can act as a platform for obtaining sp...

During the last five years, our research group has studied the architecture and evolution of several large open source systems — including Linux, GCC, VIM, Mozilla, and Apache — and we have found that open source software systems often exhibit interesting differences when compared to similar commercially-developed systems. Our investigations of these systems have involved the creation of softwa...

This paper focuses on aspects of tone in Singlish, the (mesolectal/basilectal) variety of English spoken in Singapore, which take up the claim of tone being a marked feature in contact varieties. While the source of tonal properties may well be the dominant Sinitic substrates, the actual patterning, at both word and phrase level, would appear to actually be a consequence of prosodic patterns fo...

0 Know, oh my children, that very long ago, in the Eastern city of Baghdad, there lived an old man named Ali Baba. Every day Ali Baba would go to the bazaar to buy or sell things. This is a story which is partly about Ali Baba, and partly also about a cave, a strange cave whose secret and wonder exist to this day. But I get ahead of myself . . . One day in the Baghdad bazaar a thief grabbed a p...

Capitals ownership is an important element in ensuring the sustainability of small-scale businesses. This paper discusses business capitals owned by late-night bazaar entrepreneurs selected areas Klang Valley. Based on adapted concept community Hart (2000), this study aims to examine through assessing their level social capital, human financial capital and physical capital. A total 250 late nig...

In this paper, we introduce and discuss various elements of emerging translation ecosystems that facilitate new community-based, collaborative and crowdsourced approaches and business models based on cloud computing technology platforms, smart marketplaces with aggregation, recombination and hyperdistribution, and that make the online world and its user services exponentially better than the si...
