In overlay networks, both local and long-distance links appear as a single hop to a routing protocol. Traditional routing metrics (based on hop count or packet loss) fail to take the differences between such links into account. In this paper, we study a metric based on packet delay that has been designed to improve routing in overlay networks. We show a lightweight technique for measuring delay...

In this paper, we describe a modeling framework which allows us to reason about the social-cultural behavior of humans in interaction scenarios. The objective is to provide explanatory and predictive power to an agent or robot which either witnesses or participates in the interaction: why have the human agents behaved the way they are and what kind of behavior can I expect as an answer to certa...

Design Retrospective cohort study of U.S. acute care hospitals between 2003 and ...

The manufacturing organizations today are having a competition of supply chain versus supply chain. Existing research work fails to relate human metrics with supply chain performance. The authors intend to empirically assess the effects of human metrics on supply chain performance in the context of Indian manufacturing organizations. A rigorous literature review has identified 12 variables. The...

Since the 1970s, services marketing has grown into a major sub discipline of marketing. It is constantly claimed – but is refuted in the article – that services are now the dominant economic activity in developed countries and keeps growing while the two traditional goods sectors, manufacturing and agriculture, are declining.

This paper examines the structure of the Korean package tour industry in Australia. Because of the demand by Korean consumers for cheap package tours, Korean tour wholesalers have lowered the wholesale package price to travel retailers to maintain market share. Rather than suffering a fall in profit from lower receipts, the Korean wholesale sector has forced the Inbound Tour Operator sector in ...
