Background: Identifying lower extremity defects during high impact activity, such as landing, especially in young athletes who play team sports, could help to prevent non-contact lower extremity injuries. The Tuck Jump Assessment (TJA) is a screening instrument designed to recognize neuromuscular deficits related to Anterior Cruciate Ligament (ACL) injury. The current study investigated the pre...

Data from the urban renewal experience in Syracuse, New York are used to examine the impact of race on patterns of intra-urban migration. The results show that, overall, the migration patterns exhibited an exponential decay in frequency with increasing distance. Both blacks and whites display this pattern, but blacks tend to cluster more closely around the point of origin. Indirect evidence is ...

In this contribution we investigate a simple pattern formation process [9,10] based on Hebbian learning and competitive interactions within cortex. This process generates spatial representations of afferent (sensory) information which strongly resemble patterns of response properties of neurons commonly called brain maps. For one of the most thoroughly studied phenomena in cortical development,...

The aim of the present study was to determine the extent to which aesthetic preference, previously attributed to cerebral dominance, may be determined by reading habits. One hundred and sixty two normal subjects were presented pairs of images, one being the mirror-image of the other, and were asked for their aesthetic preference. Half of the subjects were left-to-right readers (French subjects)...

We argue that the field of Health Policy and Management (HPAM) ought to confront the gap between theory, policy, and practice. Although there are perennial efforts to reform healthcare systems, the conceptual barriers are considerable and reflect the theory-policy-practice gap. We highlight four dimensions of the gap: 1) the dominance of microeconomic thinking in health policy analysis and desi...

Fast growing population, excessive expansion of cities, and dominance of automobile in urban life have troubled cities with complicated traffic problems. In many parts of the world, transport network development has always been considered as a solution for this problem. Apparently, one-dimensional ‘traffic solutions’ would never thoroughly bring best results as the city and its problems are com...
