Strategic Asia 2002 Final Report

Description: The Strategic Asia Program made considerable progress over the course of 2002--the program's first year with support from the Department of Energy--and completed all its tasks on schedule and within budget. Following a planning meeting in Washington in February 2002, a team of leading specialists wrote a series of original assessments regarding the impact of September 11 on the strategic environment in Asia, examining how perceptions and strategies of countries in the region changed following the terrorist attacks. The final products, Strategic Asia 2002-03: Asian Aftershocks and its accompanying executive summary, were published in September 2002. The program's research findings (some of which are summarized) were presented to policymakers in Washington and elsewhere throughout the year, and almost 2,000 copies of the book had been distributed by mid-2003.

A study in self-scheduling of high school students as opposed to computer scheduling

Description: The problem with which this investigation is concerned is that of determining success of selection of classes and satisfaction or dissatisfaction with self-scheduling as opposed to computer scheduling. A survey is made of 468 randomly selected high school students from four high schools in a large metropolitan school district.

A comparison of the academic achievements of seventh grade students in the semester unit plan with those in the quarter unit plan

Description: The problem with which this dissertation is concerned is to determine whether the semester unit plan offers seventh grade students greater academic gain in the basic subject areas than does the quarter unit plan. Texas offers school districts a choice of the two plans. This study is unique in that the district of this study has both plans in operation at the secondary level.

Using Concurrent Schedules of Reinforcement to Decrease Behavior

Description: We manipulated delay and magnitude of reinforcers in two concurrent schedules of reinforcement to decrease a prevalent behavior while increasing another behavior already in the participant's repertoire. The first experiment manipulated delay, implementing a five second delay between the behavior and delivery of reinforcement for a behavior targeted for decrease while no delay was implemented after the behavior targeted for increase. The second experiment manipulated magnitude, providing one piece of food for the behavior targeted for decrease while two pieces of food were provided for the behavior targeted for increase. The experiments used an ABAB reversal design. Results suggest that behavior can be decreased without the use of extinction when contingencies favor the desirable behavior.

Comparing Response Frequency and Response Effort in Reinforcer Assessments with Children with Autism

Description: Reinforcer assessments have largely relied on the use of progressive ratio (PR) schedules to identify stimuli that function as reinforcers. PR schedules evaluate the reinforcing efficacy of a stimulus by measuring the number of responses produced in order to access a stimulus as the number of required responses increases. The current evaluation extends the literature on reinforcer assessments by measuring responding under a progressive force (PF) schedule, in addition to progressive ratio requirements. We compared responding under PR and PF schedules with two children with autism using a multielement design embedded within a reversal experimental design. Results were mixed and implications for further development of reinforcer assessment methods (particularly PF schedules) are discussed.

Effect of Operant Behavior on the Metabolism of 5-Hydroxytryptamine

Description: The role of operant behavior in the metabolism of brain 5-hydroxytryptamine (5-HT) turnover was investigated. Two and one-half hours following the administration of 150 mg/kg of para-chlorophenylalanine (PCPA), a specific inhibitor of tryptophan hydroxylase, levels of 5-HT were compared in sedentary and performing rats. Whole brain levels of serotonin were reduced in both responding and sedentary animals; however, differences between these groups were not statistically significant. The drug induced decrease in 5-HT levels was accompanied by a significant decrease in session responding. The degree of suppressed responding could be correlated with the level of 5-HT following PCPA, suggesting that the metabolism of serotonin is in part modulated by the rate of responding as maintained by the operant schedule.

Review of recent safety programs at the Hanford Site for new in-tank equipment

Description: The general safety criteria are reviewed; examples of several different safety programs are illustrated; cost and schedule information are presented; and outlines of general safety considerations and specific safety design requirements and solutions are listed. A suggested program approach is covered in some detail.

Computational Biology and High Performance Computing 2000

Description: The pace of extraordinary advances in molecular biology has accelerated in the past decade due in large part to discoveries coming from genome projects on human and model organisms. The advances in the genome project so far, happening well ahead of schedule and under budget, have exceeded any dreams by its protagonists, let alone formal expectations. Biologists expect the next phase of the genome project to be even more startling in terms of dramatic breakthroughs in our understanding of human biology, the biology of health and of disease. Only today can biologists begin to envision the necessary experimental, computational and theoretical steps necessary to exploit genome sequence information for its medical impact, its contribution to biotechnology and economic competitiveness, and its ultimate contribution to environmental quality. High performance computing has become one of the critical enabling technologies, which will help to translate this vision of future advances in biology into reality. Biologists are increasingly becoming aware of the potential of high performance computing. The goal of this tutorial is to introduce the exciting new developments in computational biology and genomics to the high performance computing community.

Surface Environmental Surveillance Procedures Manual

Description: Environmental surveillance data are used in assessing the impact of current and past site operations on human health and the environment, demonstrating compliance with applicable local, state, and federal environmental regulations, and verifying the adequacy of containment and effluent controls. SESP sampling schedules are reviewed, revised, and published each calendar year in the Hanford Site Environmental Surveillance Master Sampling Schedule. Environmental samples are collected by SESP staff in accordance with the approved sample collection procedures documented in this manual.
