This paper uses two datasets to examine price dispersion spanning a 24-year period. The first dataset permits us to compare levels of retail price dispersion in 1976 and 2000, while the second allows for a comparison of retail dispersion in 1976 with dispersion in e-tail markets in 2000. Our results indicate that price dispersion in 2000 for both retail and(More)
Straight leg raising (SLR) is a useful clinical test to demonstrate an inflammatory compressive process across a spinal nerve root. Several previous studies have attempted to evaluate the effect of SLR on nerve root motion, but the exact direction and amount of this motion is still unclear. Components of the SLR test that have not been adequately addressed(More)
Introduction: The goal of this study was to determine the feasibility of performing quantitative magnetization transfer (qMT) at high resolution in the spinal cord on clinical 3T systems. While magnetization transfer (MT) imaging has been used to assess brain tissue microstructure, similar studies in the human spinal cord have been limited. This can largely(More)
Obtaining adequate sacral fixation is an important and challenging clinical problem. Bicortical screw fixation has been used to provide improved mechanical strength. The goal of this study was to evaluate the effects of depth of penetration (unicortical versus bicortical), orientation (medial versus lateral), and bone density on the strength of the(More)

Traditional forms of environmental regulation have been successful in achieving substantial environmental improvements. However, it is becoming increasingly clear that they will be inadequate to achieve environmental goals in a cost-effective and sustainable way. This has motivated the NSW EPA to implement a number of economic instruments to provide(More)
The mystery tradition known as Orphism is often misunderstood, largely due to the lack of evidence in existence. Mystery traditions are initiatory in nature; to reveal the secret information to non-initiates was forbidden, in some instances punishable by death. This secretive nature of mystery traditions makes it very difficult for modern scholars to(More)
