Both physical oceanographic processes and marine geological features in the continental shelf can cause the medium properties to have lateral heterogeneity, so horizontal refraction of sound can occur and produce significant three-dimensional (3-D) sound propagation effects. The long-term goals of this project are targeted on understanding the 3-D acoustic effects caused by the environmental fa...

Amyotrophic Lateral Sclerosis is a severe disease, which dramatically reduces the speech communication skills of patients as disease progresses. The present study is devoted to define accurate and objective estimates to characterize the loss of communication skills, to help clinicians and therapists in monitoring disease progression and in deciding on rehabilitation interventions. The methodolo...

The level of IT investment amongst organisations in developing economies is increasing. Growing evidence however, indicates, that the majority of these economies still fail to capitalise on their IT investment to source business values. For business values to materialise, effective governance of IT related resources is paramount. This entails that the presence of effective IT governance (ITG) s...

Lateral intracortical interactions are believed to be responsible for the sharpening of the receptive field profiles of visual cortical cells. This study demonstrates a structurally imposed limitation of long range interactions on the frequently invoked cross orientation inhibition scheme: it leads to inhomogeneous input for different cell populations which is experimentally not observed. We pr...

The detrimental effects of velopharyngeal dysfunction (VPD) on speech intelligibility in persons with progressive motor speech disorders are poorly understood. In this study, we longitudinally investigated the velopharyngeal and articulatory performance of 142 individuals with varying severities of amyotrophic lateral sclerosis (ALS). Our goal was to determine the mechanisms that underlie the e...

Simplified models of the lateral geniculate nucles (LGN) and striate cortex illustrate the possibility that feedback to the LG N may be used for robust, low-level pattern analysis. The information fed back to the LG N is rebroadcast to cortex using the LG N 's full fan-out, so the cortex-LGN-cortex pathway mediates extensive cortico-cortical communication while keeping the number of necessary c...

Prior research demonstrates product market advantages of organizational status but largely neglects factor market advantages. We propose that status is advantageous in labor markets because individuals generally consider employer status a non-pecuniary employment benefit. Dyadic analyses of lateral partner hiring by large U.S. law firms demonstrate two status-based advantages in employee hiring...
