A letter report issued by the Government Accountability Office with an abstract that begins "In February 2005, GAO issued a report that raised concerns about the effectiveness of the Department of Health and Human Services (HHS) Administration for Children and Families' (ACF) oversight of about 1,600 local organizations that receive nearly $7 billion in Head Start grants. GAO was asked to report on (1) ACF's progress in conducting a risk assessment of the Head Start program and ensuring the accuracy and reliability of data from its annual Program Information Report (PIR) survey of grantees, (2) efforts to improve on-site monitoring of grantees, and (3) how data are used to improve oversight and help grantees meet program standards. For this report, GAO surveyed a nationally representative sample of Head Start program directors and interviewed ACF officials. GAO also reviewed ACF studies on the validity of PIR data and conducted tests of data from the 2006 PIR database."

A letter report issued by the Government Accountability Office with an abstract that begins "Conflict over the use of our nation's natural resources, along with increased ecological problems, has led land managers to seek cooperative means to resolve natural resource conflicts and problems. Collaborative resource management is one such approach that communities began using in the 1980s and 1990s. A 2004 Executive Order on Cooperative Conservation encourages such efforts. GAO was asked to determine (1) experts' views on collaborative resource management, (2) how selected collaborative efforts have addressed conflicts and improved resources, and (3) challenges that agencies face as they participate in such efforts and how the Cooperative Conservation initiative has addressed them. GAO reviewed experts' journal articles, studied seven collaborative groups, and interviewed group members and federal and other public officials."

Testimony issued by the Government Accountability Office with an abstract that begins "The nation's wildland fire problems have worsened over the past decade. Recent years have seen dramatic increases in the number of acres burned and the dollars spent on preparing for and responding to wildland fires. As GAO has previously reported, a number of factors have contributed to worsening fire seasons and increased firefighting expenditures, including an accumulation of fuels due to past land management practices; drought and other stresses, in part related to climate change; and an increase in human development in or near wildlands. Recent GAO reports have identified shortcomings in the approach to wildland fire management taken by the responsible federal agencies--the Department of Agriculture's Forest Service and four agencies within the Department of the Interior. GAO was asked to testify on agency efforts to (1) develop a cohesive strategy for preparing for and responding to wildland fire, (2) contain federal expenditures related to wildland fire, and (3) improve the processes used to allocate funds for reducing accumulated fuels and to select fuel reduction projects. GAO also is providing preliminary findings from its ongoing review of an interagency budget allocation and planning model known as fire …

Testimony issued by the Government Accountability Office with an abstract that begins "Most of the funding for programs under title VII of the Public Health Service Act goes toward primary care medicine and dentistry training and increasing medical student diversity. Despite a longstanding objective of title VII to increase the total supply of primary care professionals, health care marketplace signals suggest an undervaluing of primary care medicine, creating a concern about the future supply of primary care professionals--physicians, physician assistants, nurse practitioners, and dentists. This concern comes at a time when there is growing recognition that greater use of primary care services and less reliance on specialty services can lead to better health outcomes at lower cost. GAO was asked to focus on (1) recent supply trends for primary care professionals, including information on training and demographic characteristics; (2) projections of future supply for primary care professionals, including the factors underlying these projections; and (3) the influence of the health care system's financing mechanisms on the valuation of primary care services. GAO obtained data from the Health Resources and Services Administration (HRSA) and organizations representing primary care professionals. GAO also reviewed relevant literature and position statements of these organizations."

Gas hydrates are a vast energy resource with global distribution in the permafrost and in the oceans. Even if conservative estimates are considered and only a small fraction is recoverable, the sheer size of the resource is so large that it demands evaluation as a potential energy source. In this review paper, we discuss the distribution of natural gas hydrate accumulations, the status of the primary international R&D programs, and the remaining science and technological challenges facing commercialization of production. After a brief examination of gas hydrate accumulations that are well characterized and appear to be models for future development and gas production, we analyze the role of numerical simulation in the assessment of the hydrate production potential, identify the data needs for reliable predictions, evaluate the status of knowledge with regard to these needs, discuss knowledge gaps and their impact, and reach the conclusion that the numerical simulation capabilities are quite advanced and that the related gaps are either not significant or are being addressed. We review the current body of literature relevant to potential productivity from different types of gas hydrate deposits, and determine that there are consistent indications of a large production potential at high rates over …

As part of a study to characterize the detailed coordination behavior of Pu(IV), single crystal X-ray diffraction structures have been determined for Pu(IV) and Ce(IV) complexes with the naturally-occurring ligand maltol (3-hydroxy-2-methyl-pyran-4-one) and its derivative bromomaltol (5-bromo-3-hydroxy-2-methyl-pyran-4-one). Although Ce(IV) is generally accepted as a structural analog for Pu(IV), and the maltol complexes of these two metals are isostructural, the corresponding bromomaltol complexes are strikingly different with respect to ligand orientation about the metal ion: All complexes exhibit trigonal dodecahedral coordination geometry but the Ce(IV)-bromomaltol complex displays an uncommon ligand arrangement not mirrored in the Pu(IV) complex, although the two metal species are generally accepted to be structural analogs.

Various model equations are available for representing the excess Gibbs energy properties (osmotic and activity coefficients) of aqueous and other liquid mixed-electrolyte solutions. Scatchard's neutral-electrolyte model is among the simplest of these equations for ternary systems and contains terms that represent both symmetrical and asymmetric deviations from ideal mixing behavior when two single-electrolyte solutions are mixed in different proportions at constant ionic strengths. The usual form of this model allows from zero to six mixing parameters. In this report we present an analytical method for transforming the mixing parameters of neutral-electrolyte-type models with larger numbers of mixing parameters directly to those of models with fewer mixing parameters, without recourse to the source data used for evaluation of the original model parameters. The equations for this parameter conversion are based on an extension to ternary systems of the methodology of Rard and Wijesinghe [J. Chem. Thermodyn. 35, 439-473 (2003)] and Wijesinghe and Rard [J. Chem. Thermodyn. 37, 1196-1218 (2005)] that was applied by them to binary systems. It was found that the use of this approach with a constant ionic-strength cutoff of I {le} 6.2 mol {center_dot} kg{sup -1} (the NaCl solubility limit) yielded parameters for the NaCl + SrCl{sub 2} …

The High Exposure Facility is a collimated high-level gamma irradiator that is located in the basement of the 318 building. It was custom developed by PNNL back in 1982 to meet the needs for high range radiological instrument calibrations and dosimeter irradiations. At the time no commercially available product existed that could create exposure rates up to 20,000 R/h. This document is intended to pass on the design criteria that was employed to create this unique facility, while maintaining compliance with ANSI N543-1974, "General Safety Standard for Installations Using Non-Medical X-Ray and Sealed Gamma-Ray Sources, Energies up to 10 MeV."

The indoor atmosphere is an ecological unit that impacts on public health. To investigate the composition of organisms in this space, we applied culture-independent approaches to microbes harvested from the air of two densely populated urban buildings, from which we analyzed 80 megabases genomic DNA sequence and 6000 16S rDNA clones. The air microbiota is primarily bacteria, including potential opportunistic pathogens commonly isolated from human-inhabited environments such as hospitals, but none of the data contain matches to virulent pathogens or bioterror agents. Comparison of air samples with each other and nearby environments suggested that the indoor air microbes are not random transients from surrounding outdoor environments, but rather originate from indoor niches. Sequence annotation by gene function revealed specific adaptive capabilities enriched in the air environment, including genes potentially involved in resistance to desiccation and oxidative damage. This baseline index of air microbiota will be valuable for improving designs of surveillance for natural or man-made release of virulent pathogens.
