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.

Forecasting Cash Flow: Mathematics of the Payout Ratio
We all have used the Discounted Cash Flow (DCF) method. Many of us would agree that it is generally the best, most comprehensive, theoretically correct valuation model. It also has an empirical reason to be the best, which is that many of us calculate our discount rates using the Ibbotson data in the SBBI annual yearbooks, which are based on publicly traded stock data.

Corporate Governance: How to Act in a Post Bailout Era
Corporate governance refers to the manner in which a company is directed by its board of directors.

Psychologically Speaking©: Negotiation 101
By: Kenneth J. Manges, PhD, ABVE, CVE, CFP
Advice about negotiation often focuses on procedure, strategy, and tactics. However, some of the most important factors in dispute resolution are the subliminal aspects of the interaction that operate outside the awareness of the participants, which may create unnecessary barriers to the effective resolution in dispute.
