This paper considers the diagnostic value of a computer screening system as an alternative, or adjunct, to traditional battery testing systems in identifying the presence of specific learning disabilities (SLD) in university students. In the present times of increasing numbers of students with various forms of disabilities entering tertiary education, institutional fiscal constraints, problems ...

Following the recent analysis of Lucas and Rossi-Hansberg [10], we study the equilibrium structure of cities. By adopting a different (monetary) specification of commuting costs, we are able to prove the existence of equilibrium in more general situations: non-circular cities, or multi-sectorial production. The main mathematical tool in this paper is the use of optimal transportation theory. Th...

Considering a worldwide tendency, air transports are growing very fast and many changes have taken place in planning, management and decision making process. Given the complexity of airport operation, the best use of existing capacity is the key driver of efficiency and productivity. This paper deals with the evaluation framework for the ground access at airports, by using a set of mode choice ...

Building simple and accurate models of hub airports can considerably help one understand airport dynamics, and may provide quantitative estimates of operational airport improvements. In this paper, three models are proposed to capture the dynamics of busy hub airport operations. Two simple queuing models are introduced to capture the taxi-out and taxi-in processes. An integer programming model ...

The development of a Multiple Airport Region (MAR) could lead to fierce competition. To evaluate the level homogenization between airports in MAR, evaluation method based on multi-dimensional indicators was developed. A indicator system is proposed that takes into account infrastructure, integrated support, operational efficiency and airline networks. Then Critic Delphi are used assign hierarch...
