Introduction The Airline Deregulation Act (ADA) of 1978 caused many changes in the industry. For the first time in 40 years, new airlines were permitted to enter the industry, and all airlines could choose the routes they would serve and the fares they would charge. Airlines were also free to exit the industry (go bankrupt), if they made poor choices in these matters. Naturally, this has led to...

Purpose: The objective of this research is to identify and characterize the coordination systems used by SME hub firms that are in a situation of dependence with respect to other members of their network, taking into account the influence of hub firm size. Design/methodology/approach: Seven case studies were carried out: six innovation networks in which SMEs play a central role are compared wit...

Hub location problems are strategic network planning problems. They formalise the challenge of mutually exchanging shipments between a large set of depots. The aim is to choose a set of hubs (out of a given set of possible hubs) and connect every depot to a hub so that the total transport costs for exchanging shipments between the depots are minimised. In classical hub location problems, the un...

Identification of hub proteins from sequence is a challenge in molecular biology. Therefore, it is of interest to predict protein hubs in networks. We describe the prediction of protein "hub" using physiochemical, thermodynamic and conformational properties of amino acid residues in sequence. We have used twenty sequence based features to identify hub behaviour. Linear discriminant analysis and...
