Environmental radiological assessments rely heavily on the use of mathematical models. The predictions of these models are inherently uncertain because these models are inexact representations of real systems. The major sources of this uncertainty are related to biases in model formulation and...

The Department of Energy's (DOE) Small Business Program is characterized by its diligent involvement in the procurement process to enhance participation by small businesses, small disadvantaged businesses, labor surplus area firms, and women-owned businesses. The DOE's primary means of securing...

Using a system dynamic model (SDM), such as STELLA, to analyze the waste management policy is a new trial for Taiwan's research communities. We have developed an easy and relatively accurate model for analyzing the greenhouse gases emission for the wastes from animal farming and municipalities....

This report documents Reynolds Electrical Engineering Co., Inc., analysis of all major job groups with explanations if minorities and females are underutilized in any one or more job group. Goals and timetables have been developed and good faith efforts are directed to correct any deficiencies....

This paper advocates the utility of mathematical models, as contrasted with statistical procedures and processional judgment, for assessing environmental impacts. While it would be desirable to use statistical tests to detect and estimate impacts, this is generally difficult or impossible to do,...

Growing trees with crops has environmental and economic implications. Trees can help prevent landdegradation and increase biodiversity while at the same time allow for the continued use of the land toproduce agricultural crops. In fact, growing trees alongside crops is known to improve both the...

Increasingly, environmental problems are recognized to involve linkages across multiple environmental variables (e.g., pollution and a fishery). Prior work on managing these complex, linked systems generally focuses on efficiency rather than implementation. However, implementation is important...

We develop a dynamic model of livestock disease and decentralized economic behavior as a jointly-determined system. By accounting for feedbacks between behavioral choices and disease outcomes we capture the endogenous nature of infection risks. We consider government mandated testing of...
