Supply chain management is an area which gains much attention both from scholars and practitioners when considering the relationship between economic and ecologic issues and goals. Initiatives from Green IT and Green IS are widely discussed and broad supply chain management concepts like Green SCM, which extends the concept of global supply chain management with ecological aspects like resource...

any of the myriad problems in the u.s. mortgage market could have been contained, but together they caused a crisis that spread across the globe T HE causes of the crisis in subprime mortgages have become clear. They started with poor underwriting practices, which became legion. But damage was propagated at each stage of the complicated process in which a risky home loan was originated, then be...

Recent debate amongst some sections of the diving community has concerned the relative benefits of using new ascent and decompression strategies based on calculations of the presence and behaviour of microbubbles. This debate has extended to concern over the relative safety of standard entry level agency decompression/no stop tables. The concern stems from the fact that recent research and opin...

A wireless sensor network (WSN) provides a barrier-coverage over an area of interest if no intruder can enter the area without being detected by the WSN. Recently, barrier-coverage model has received lots of attentions. In reality, sensor nodes are subject to fail to detect objects within its sensing range due to many reasons, and thus such a barrier of sensors may have temporal loopholes. In c...

There are several approaches for using computers in deriving mathematical proofs. For their illustration, we provide an in-depth study of using computer support for proving one complex combinatorial conjecture – correctness of a strategy for the chess KRK endgame. The final, machine verifiable, result presented in this paper is that there is a winning strategy for white in the KRK endgame gener...

It is estimated that at least two billion people have inadequate sanitation. The current situation in water and sanitation services for millions of peri-urban residents is starkly antipoor and represents a major challenge for the 21 century. By virtue of its cost and water requirements, we would argue that conventional sewerage is an implicitly anti-poor technology. This paper summarises low-co...

Enthusiasm about the educational benefits offered by the World Wide Web has been tempered in recent years by apprehension regarding the prospects of mitigating associated online threats. Numerous safety measures exist, from legislation to technical controls. Though no doubt helpful, they are not substitutes for education and training. The current study (N = 1,092) aimed at identifying technolog...

We examine the announcement period stock returns for 179 over-the-counter (OTC) firms that issue common stock to reduce nonconvertible debt. We find that small OTC firms experience returns that are significantly more negative than large OTC firms. Regression tests reveal that firm size is a significant factor in accounting for stock returns. Other tests establish firm size as a dominant effect....
