This paper introduces dependency centrality, a node-level measure of structural leadership in bipartite networks. The measure builds on Zhou et al.’s (2007) flow-based method to transform bipartite data and captures additional information from the second mode that existing measures of centrality typically exclude. Three previously published bipartite networks serve as test cases to demonstrate ...

Interactions between evolution and lifetime learning are of great interest to studies of adaptive behaviour both in the natural world and the field of evolutionary computation. This contribution revisits an earlier discovered observation that the average performance of a population of neural networks which are evolved to solve one task is improved by lifetime learning on a different task. Two e...

The success of antiretroviral therapy (ART) for HIV infection, though widespread and resounding, has been limited by inadequate adherence to its unforgiving regimens, especially over the long term. This article summarizes the literature on behavioral interventions to promote ART adherence and highlights some of the most recent and innovative research on patient education and case management, mo...

This paper seeks to contribute to current debate on evidence-based practice and appropriate models of disability rehabilitation for people with disabilities in developing countries. Based on the authors’ experience in, and evaluation of Community Based Rehabilitation (CBR) projects and research, they provide suggestions for utilising different kinds of evidence at different levels of CBR. The p...

BACKGROUND AND PURPOSE Purtilo, Guccione, and others have noted that increased clinical autonomy for physical therapists presents more complex ethical dilemmas. The body of literature examining physical therapy ethics, however, is relatively small and has not been analyzed. The primary purposes of this research were: (1) to use multiple perspectives to describe and analyze literature examining ...

objective: many behavioral problems are resulting from inappropriate parenting styles and inattention to behavioral-emotional difficulties in childhood. the purpose of this research was to examine the relationship between parenting styles and dimensions of children's maladaptive behaviors. methods: 120 six-year old boys, who were enrolled in the first grade of elementary school, were selec...

To improve heat and ablation rate modeling of the thermal protection system for reentry vehicles, a material response model with surface ablation and pyrolysis is developed. To accurately model the effects of the pyrolysis gas within the ablator, Darcy’s law is replaced by Forchheimer’s law for flow through porous media. The use of Forchheimer’s law accounts for the inertial effects of the gas ...

ÐThe coterie join operation proposed by Neilsen and Mizuno produces, from a k-coterie and a coterie, a new k-coterie. For the coterie join operation, this paper first shows 1) a necessary and sufficient condition to produce a nondominated k-coterie (more accurately, a nondominated k-semicoterie satisfying Nonintersection Property) and 2) a sufficient condition to produce a k-coterie with higher...

Given a prediction of opponent behavior in a generalsum two-player normal form game, it is difficult to select a strategy that balances the opportunity to use the prediction to inform one’s action with the risk of becoming predictable. We propose Restricted Stackelberg Response with Safety (RSRS), a novel way of generating such a strategy. RSRS uses an r-safe Stackelberg equilibrium in a modifi...
