The notion of the ‘productivity puzzle,' referring particularly to gender disparities in science and technology publication rates, raises a variety of critical issues for understanding related workforce development and capacity. However, such issues typically are framed relative to an...

Epistemic communities have been identified and studied through collaboration and citation analyses. One issue that has received increasing calls for research in this area is the role of gender, especially in light of significant variation in participation and productivity along gender lines....

Improvements in telecommunications and transportation appear to be bringing the world closer making physical location less of a factor in determining interaction between nations. The formation of regional and global trading pacts and arrangements seem to be further contribution to this...

Foreclosures are spatially contagious by nature (Can 1998). Abandoned or vacant properties have a negative spillover effect, by reducing the expected return on investment on surrounding properties. While there is a growing body of literature focusing on the latest wave of foreclosures in the US...

In this paper we develop an exploratory non-parametric clustering model of spatial and/or spatio-temporal phenomena based on Kolmogorov entropy. The methodology will be tested using quarterly HPI (Housing Price Index) data for 350 plus cities in the US from the Federal Financing and Housing...

Disruptions to transportation networks can be very costly. However, managing disruptions and the costs associated with these events, poses some challenges. Transport networks are, in many cases, large and complex. This paper develops a method, based on complex network theory, to analyse...

Context: Online social networks and the Web 2.0 technologies embedded in these sites are creating an environment in which individuals can communicate and share information in ways that were previously not possible. Such websites are providing an unprecedented and growing collection of data on...

In this paper we explore the development of a parameter free region classifier based on Kolmogorov complexity. Given a set of regions described by unlimited but fixed number of attributes for each region, the region classifier will be able to build a classification tree which will help identify...

The events of 11 September 2001 brought an increased focus on security in the United States and specifically the protection of critical infrastructure. Critical infrastructure encompasses a wide array of physical assets such as the electric power grid, telecommunications, oil and gas pipelines,...
