A letter report issued by the Government Accountability Office with an abstract that begins "According to U.S. intelligence, the threat to U.S airspace remains. The North American Aerospace Defense Command (NORAD) is to defend U.S. air space and the U.S. Air Force has 18 sites in the United States that conduct air sovereignty alert (ASA) operations. ASA operations support fighter aircraft in conducting homeland air defense operations. GAO examined the extent to which (1) NORAD has adopted a risk-based management approach to determine ASA operational requirements; (2) the Air Force has implemented ASA operations as a steady-state mission in accordance with Department of Defense (DOD), NORAD, and Air Force directives and guidance; (3) the Air Force assesses the readiness of units conducting ASA operations; and (4) the Air Force faces challenges in sustaining ASA operations for the future and what plans, if any, it has to address such challenges. GAO reviewed relevant ASA guidance, directives, and planning documents; and interviewed DOD officials, including the commanders of all 18 ASA sites."

A letter report issued by the Government Accountability Office with an abstract that begins "Workers who "blow the whistle" on prohibited practices play a role in enforcing federal laws, but these workers risk reprisals from their employers. The Whistleblower Protection Program at the Department of Labor's (Labor) Occupational Safety and Health Administration (OSHA) is responsible for investigating whistleblowers' complaints. OSHA's decisions generally may be appealed to the Office of Administrative Law Judges (OALJ) and, ultimately, the Administrative Review Board (ARB). GAO examined (1) what is known about processing times for complaints and what affects these times, (2) what outcomes resulted, and (3) what challenges OSHA faces in administering the program. To answer these questions, GAO analyzed electronic data files from OSHA, OALJ, and ARB; visited five OSHA regional offices; reviewed case files; conducted a Web-based survey of investigators; and interviewed key officials."

A letter report issued by the General Accounting Office with an abstract that begins "SSA oversees and fully funds primarily state-operated DDSs that determine whether applicants are eligible for disability benefits. The disability examiners employed by the DDSs play a key role in determining benefit eligibility. This report examines (1) the challenges the DDSs face today in retaining and recruiting examiners and enhancing their expertise; (2) the extent to which the DDSs engage in workforce planning and encounter obstacles in doing so; and (3) the extent to which SSA is addressing present and future human capital challenges in the DDSs."

A letter report issued by the General Accounting Office with an abstract that begins "By positively confirming identifications and linking relevant records of arrests and prosecutions, fingerprint analysis provides a basis for making fundamental criminal justice decisions regarding detention, charging, bail, and sentencing. In 1999, the FBI implemented the Integrated Automated Fingerprint Identification System (IAFIS)--a computerized system for storing, comparing, and exchanging fingerprint data in a digital format. The FBI's goal under IAFIS is to ultimately achieve paperless processing and to provide a response within 2 hours to users who submit criminal fingerprints electronically. Maximizing the benefits of rapid responses under IAFIS depends largely on how quickly criminal fingerprints are submitted by local and state law enforcement agencies. Concerns have been raised that, after arrests are made by some local or state law enforcement agencies, periods of up to 6 months may elapse before the criminal fingerprints are submitted for entry into IAFIS. GAO examined (1) the importance of IAFIS processing to local and state law enforcement agencies, (2) the progress these agencies have made toward the goal of paperless fingerprint processing, and (3) efforts being made to improve the timeliness of criminal fingerprint submissions."

A letter report issued by the Government Accountability Office with an abstract that begins "Primarily because of concerns that noise from air tours over national parks could impair visitors' experiences and park resources, Congress passed the National Parks Air Tour Management Act of 2000 to regulate air tours. The act requires the Federal Aviation Administration (FAA) and the National Park Service to develop air tour management plans for all parks where air tour operators apply to conduct tours. A plan may establish controls over tours, such as routes, altitudes, time of day restrictions, and/or a maximum number of flights for a given period; or ban all air tours. GAO was asked to (1) determine the status of FAA and the Park Service's implementation of the act; (2) assess how the air tour operators and national parks have been affected by implementation; and (3) identify what issues, if any, need to be addressed to improve implementation."

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO provided information on mandatory country-of-origin labelling for beef and lamb, focusing on the potential: (1) compliance costs associated with mandatory country-of-origin labelling for fresh and processed beef and lamb; (2) enforcement costs associated with such a requirement; (3) trade issues associated with such a requirement; and (4) benefits of mandatory country-of-origin labelling."

A letter report issued by the General Accounting Office with an abstract that begins "Since the September 11, 2001, attacks and the beginning of Operation Iraqi Freedom, thousands of National Guard and Reserve members have been activated and mobilized to military installations across the country. Some installations, like MacDill Air Force Base in Tampa, Florida, where more than 3,000 reservists have been mobilized, have had to arrange for off-base lodging in local hotels and apartment buildings. In addition, MacDill, which serves as U.S. Central Command headquarters, has had to set up temporary office space for staffs of coalition partner nations. Public concerns have been raised about these arrangements. GAO was asked to review (1) the extent to which MacDill used cost-effective measures to provide off-base lodging for reservists and (2) whether a contract providing office space for coalition partners was adequately managed to control costs."

A letter report issued by the Government Accountability Office with an abstract that begins "Terrorist attacks on U.S. chemical facilities could damage public health and the economy. While the Environmental Protection Agency (EPA) formerly led federal efforts to ensure chemical facility security, the Department of Homeland Security (DHS) is now the lead federal agency coordinating efforts to protect these facilities from terrorist attacks. GAO reviewed (1) DHS's actions to develop a strategy to protect the chemical industry, (2) DHS's actions to assist in the industry's security efforts and coordinate with EPA, (3) industry security initiatives and challenges, and (4) DHS's authorities and whether additional legislation is needed to ensure chemical plant security. GAO interviewed DHS, EPA, and industry officials, among others."

The Manufactured Home Energy Audit (MHEA) is a software tool that predicts manufactured home energy consumption and recommends weatherization retrofit measures. It was developed to assist local weatherization agencies working with the U.S. Department of Energy (DOE) Weatherization Assistance Program. Whether new or experienced, employed within or outside the Weatherization Assistance Program, all users can benefit from incorporating MHEA into their manufactured home weatherization programs. DOE anticipates that the state weatherization assistance programs that incorporate MHEA into their programs will find significant growth in the energy and cost savings achieved from manufactured home weatherization. The easy-to-use MHEA uses a relatively standard Windows graphical interface for entering simple inputs and provides understandable, usable results. The user enters information about the manufactured home construction, heating equipment, cooling equipment appliances, and weather site. MHEA then calculates annual energy consumption using a simplified building energy analysis technique. Weatherization retrofit measures are evaluated based on the predicted energy savings after installation of the measure, the measure cost, and the measure life. Finally, MHEA recommends retrofit measures that are energy and cost effective for the particular home being evaluated. MHEA evaluates each manufactured home individually and takes into account local weather conditions, retrofit measure costs, and …

The collaboration between Mark Fink (Tulane University) and R. Morris Bullock (Brookhaven National Laboratory, currently at PNL) is an effort to understand some of the fundamental processes involved in catalytic bond activations with low coordinate palladium species. The project involves the photochemical generation of reactive low-valent palladium species as transients using nanosecond laser flash photolysis and the subsequent investigation of their reactions with chloroarenes and hydrosilanes. In the case of Si-H activation of hydrosilanes, relatively long-lived sigma complexes are implicated. These complexes may be important models for C-H activation in hydrocarbons. The information obtained from these studies will help in the understanding of fundamental processes involved in a number of important catalytic reactions in the petrochemical and environmental areas.

Suppose that we are given two probability densities p{sub 0}(E{prime}) and p{sub 1}(E{prime}) for the energy E{prime} of an outgoing particle, p{sub 0}(E{prime}) corresponding to energy E{sub 0} of the incident particle and p{sub 1}(E{prime}) corresponding to incident energy E{sub 1}. If E{sub 0} < E{sub 1}, the problem is how to define p{sub {alpha}}(E{prime}) for intermediate incident energies E{sub {alpha}} = (1 - {alpha})E{sub 0} + {alpha}E{sub 1} with 0 < {alpha} < 1. In this note the author considers three ways to do it. They begin with unit-base interpolation, which is standard in ENDL and is sometimes used in ENDF. They then describe the equiprobable bins used by some Monte Carlo codes. They then close with a discussion of interpolation by corresponding-points, which is commonly used in ENDF.

This report focuses on proposals offered to amend the federal income tax code to subsidize the expenses of families with children enrolled in the K-12 school of their choice. It begins with a discussion of K-12 education reform efforts to provide a context for the proposed tax subsidies. Next, it reviews existing federal tax provisions that could help families pay for the cost of their children’s K-12schooling. The report then analyzes the kind of proposals that have been introduced to expand existing federal tax benefits or to authorize new ones for families incurring K-12 education expenses.

The Institute of Geophysics and Planetary Physics (IGPP) is a Multicampus Research Unit of the University of California (UC). IGPP was founded in 1946 at UC Los Angeles with a charter to further research in the earth and planetary sciences and related fields. The Institute now has branches at UC campuses in Irvine, Los Angeles, San Diego, Santa Cruz and Riverside, and at Los Alamos National Laboratory and Lawrence Livermore National Laboratory. The University-wide IGPP has played an important role in establishing interdisciplinary research in the earth and planetary sciences. For example, IGPP was instrumental in founding the fields of physical oceanography and space physics, which at the time fell between the cracks of established university departments. Because of its multicampus orientation, IGPP has sponsored important inter-institutional consortia in the earth and planetary sciences. Each of the seven branches has a somewhat different intellectual emphasis as a result of the interplay between strengths of campus departments and Laboratory programs. The IGPP branch at Lawrence Livermore National Laboratory (LLNL) was approved by the Regents of the University of California in 1982. IGPP-LLNL emphasizes research in tectonics, geochemistry, and astrophysics. It provides a venue for studying the fundamental aspects of these fields, …

Abstract We conduct a detailed test of a recently developed technique, CAPloc, in recovering source parameters from a few stations against results from a large broadband network in Southern California. The method uses a library of 1D Green’s functions which are broken into segments and matched to waveform observations with adjustable timing shifts. These shifts can be established by calibration against a distribution of well-located earthquakes and assembled in tomographic images for predicting various phase-delays. Synthetics generated from 2D cross-sections through these models indicates that 1D synthetic waveforms are sufficient in modeling but simply shifted in time for most hard-rock sites. This simplification allows the source inversion for both mechanism and location to easily obtain by grid search. We test one-station mechanisms for 160 events against the array for both PAS and GSC which have data since 1960. While individual solutions work well (about 90%), joint solutions produce more reliable and defensible results. Inverting for both mechanism and location also works well except for certain complex paths across deep basins and along mountain ridges.
