Dosimetric Effects Near Implanted Vascular Access Ports: An Examination Of External Photon Beam Dose Calculations

By: Michael Gossman, MS, DABR, RSO, et al

Vascular access ports are used widely in the administering of drugs for radiation oncology patients. Their dosimetric effect on radiation therapy delivery in photon beams has not been rigorously established. In this work, the effects on external beam fields when any of a variety of vascular access ports were included in the path of a high energy beam are studied. This study specifically identifies sidescatter and backscatter consequences as well as attenuation effects.

Reviewing Drivers' Logs

By: Ned Einstein

In my review of more than 80 public transportation-related accidents and law suits, one almost universal theme has been the absence of any log review. This failure has generally combined with another common theme: A vehicle running behind schedule. The relationship between these two themes is easy to both understand and demonstrate - as is the acknowledgement that they constitute a genuine safety problem. But in a courtroom, the fact that system management failed to notice the vehicle running late - and worse, failed to even look for it - translates into a liability problem as well.

Forensic Engineering Experts: Products Liability

By: Kristopher J. Seluga, PE

An end user of a product expects that a given product will not only function as intended, but will be safe from non-obvious hazards. Based upon decades of experience with mishaps during use of common and specialized equipment, thousands of standards have been developed for many consumer products and industrial equipment. Numerous organizations exist, e.g., ANSI, ASTM, SAE, and ASME, that regularly review and update these standards.

Role of the Urban Traffic Engineer

By: Richard Beaubien

At the 1981 ITE Annual Meeting in Boston a seminar was convened on the role of the urban traffic engineer. It featured some of outstanding veterans of the profession, and each offered their insights on the role of the urban traffic engineer. Speakers included Bill VanGelder from Seattle, Harold Michael from Purdue, and Bill Mc Grath who was once the Traffic Commissioner for the City of Boston.

Using De Facto Learning Theory To Understand Urban School Mobility

By: Dr. Virginia Rhodes

"All children can learn," is a catchphrase currently making the rounds in education circles, particularly in staff development activities (Pankratz & Petroski, 2003). De facto learning theory challenges the underlying assumptions of this phrase by examining how it is that learning in schools takes place. Using theoretical foundations of Dewey, Maslow, and Vygotsky, this essay will explore the fact that all children are, in fact, learning all the time, regardless of the actions of teachers, the content of the curriculum, or educational policy and practice.
