Little is known about the perpetration of violence by women who engage in street prostitution. While some researchers have examined the incidence of abuse among this population, the association between receipt of abuse and violence and later perpetration of violence is unclear. This study presents data from a recent evaluation of a case management program for street-walking prostitutes. A description of the program clients is provided, and factors that are associated with assaultive behavior against clients are examined. Bivariate analyses revealed statistically significant differences between assaultive and nonassaultive women with regard to history of psychiatric hospitalization, history of sexual abuse, history of physical abuse, history of emotional abuse, and whether they had been assaulted on the streets. However, logistic regression on variables related to abuse and violence indicates that controlling for other variables, the only statistically significant predictor of assaultive behavior was history of physical abuse. These results indicate the need for further research on this population as well as access to treatment for these women to address their own abuse and victimization.
W E BELIEVE that a clear understanding of the relevant and essential variables pertaining to the use and evaluation of aides in the present and future of health services delivery is essential.
However, the ultimate advantage of separating rendering from viewpoint selection is that it becomes possible to render the same scene for multiple eyes. Possible applica-tions include shared virtual environments (stereo viewing by many participants of a computer-generated scene). In the future, view-independent graphics rendering hardware will also be essential to support the multitude of viewpoints required for real-time autostereoscopic and holographic display devices.
AbstractWe present a new computer graphics rendering architecture that allows "all possible views" to be extracted from a single traversal of a scene description. It supports a wide range of rendering primitives, including polygonal meshes, higher-order surface primitives (e.g. spheres, cylinders, and parametric patches), point-based models, and image-based representations. To demonstrate our concept, we have implemented a hardware prototype that includes a 4D, z-buffered frame-buffer supporting dynamic view selection at the time of raster scan-out. As a result, our implementation supports extremely low display-update latency. The PixelView architecture also supports rendering of the same scene for multiple eyes, which provides immediate benefits for stereo viewing methods like those used in today's virtual environments, particularly when there are multiple participants. In the future, view-independent graphics rendering hardware will also be essential to support the multitude of viewpoints required for real-time autostereoscopic and holographic display devices.

Winchester Ammunition has developed a bullet that was specifically designed to perform better than other hollow-point missiles. The resulting cartridge, the Black Talon bullet offers a low-velocity missile that retains its weight, penetrates even when interrupted by intervening objects, and remains capable of expansion in soft tissue. The bullet causes extensive tissue damage and presents a hazard to those responsible for handling it after expansion.
