cognitive deficits such as impairments in attention, memory, information processing and executive functioning can be found in some parkinson's disease (pd) patients. recent studies suggested that pd drivers generally performed poorer than their healthy age-matched controls with regards to their cognitive and motor abilities during the psychometric testing. according to michon’s model of ca...

Most existing spatio-temporal urban expansion models consider urban land-use as a binary process, through the identification of urban versus non-urban areas. The main aim of this study is to analyze and model the expansion of multiple urban densities in Wallonia, Belgium. To this end, this study employs a multinomial logistic regression model that enables to visualize the consequence of differe...

While it is generally assumed that global plate motions are driven by the pattern of convection in the Earth’s mantle, the details of that link remain obscure. Bouyancy forces associated with subduction of cool, dense lithosphere at zones of plate convergence are thought to provide significant driving force, but the relative magnitudes of other driving and resisting forces are less clear, as ar...

Stated choice models based on the random utility framework are becoming increasingly popular in the applied economics literature. The need to account for respondents’ preference heterogeneity in such models has motivated researchers in agricultural, environmental, health and transport economics to apply random parameter logit and latent class models. In most of the published literature these mo...

There are numerous examples of assets with identical payout streams being priced differently. These violations of the law of one price result from two factors. First, investors have heterogeneous asset valuations so that if two groups of investors trade in segmented markets they are likely to set different prices because they have different expectations as to the value of the identical assets. ...

During recession, many macroeconomic variables display higher levels of volatility. We show how introducing an AR(1)-ARCH(1) driving process into the canonical Lucas consumption CAPM framework can account for the empirically observed greater volatilty of asset returns during recessions. In particular, agents' joint forecasting of levels and time-varying second moments transforms symmetric-volat...

Collaborative recommendation is an information-filtering technique that attempts to present information items that are likely of interest to an Internet user. Traditionally, collaborative systems deal with situations with two types of variables, users and items. In its most common form, the problem is framed as trying to estimate ratings for items that have not yet been consumed by a user. Desp...

for an Invited Paper for the MAR11 Meeting of The American Physical Society Jamming Mechanisms and Density Dependence of Dynamic Heterogeneities in a Kinetically-Constrained Model YAIR SHOKEF, Weizmann Institute of Science Experiments on granular [1] and colloidal [2] systems show steady growth in dynamic heterogeneities as the relaxation time increases with increasing density. In glass-forming...
