Time resolution performance studies of contemporary high speed photomultipliers
The time resolution capabilities of prototype microchannel plate and static crossed-field photomultipliers have been investigated. Measurements were made of electron transit time, rise time, time response, single photoelectron time spread and multiphotoelectron time spread for LEP HR350 proximity focused high gain curved microchannel plate and VPM-154A/1.6L static crossed-field photomultipliers. The experimental data have been compared with results obtained with conventionally designed RCS 8850 and C31024 high speed photomultipliers. Descriptions are given of both the measuring techniques and the measuring systems.

Detection and measurement of Post-Rosenbluth convective instability in MFTF with a hybrid CO/sub 2/ laser--heterodyne diagnostic system
To measure and classify the Post-Rosenbluth convective loss-cone instability in MFTF, we propose to use a CO/sub 2/ laser consisting of a TEA-pulsed section and a low pressure CW section, together with a light mixing receiver. Calculations show that this system offers sufficient power and sensitivity to detect instability throughout the range from strong coherent light scattering to weak incoherent scattering when the instability is eliminated.

Nickel--chromium strain gages for cryogenic stress analysis of superconducting structures in high magnetic fields
Evaluation and calibration measurements were performed on commercial nickel-chromium metal-foil strain gages in a high-magnetic-field (12 T), liquid-helium (4.2 K) environment. The purpose was to fully characterize strain gages for use at cryogenic temperatures in high magnetic fields. In this study, the magnetoresistance of a number of strain gages was measured in three orthogonal directions at mechanical strain levels to 8900 ..mu..m/m. As a result, a unique calibration curve was defined for magnetoresistance strain errors that is independent of strain level and field direction to 12 T at 4.2 K. A current strain-gage application is the measurement of superconductor mechanical properties. These gages will soon be used in the stress analysis of superconducting fusion magnets during cooldown from ambient temperatures and during operation at 4.2 K with magnetic fields to 12 T.

Food Safety on the Farm: Federal Programs and Legislative Action
In recent years, major outbreaks of foodborne illnesses, product recalls, and reports about unsafe food imports have caused some to question the adequacy of the U.S. food safety system. Stakeholders appear to agree that an optimal system should encompass a comprehensive, preventive approach to food safety, focusing on those foods and points in the food system that pose the greatest public health risks, starting at the point of production - that is, on farms and ranches. This report discusses differing opinions on this topic, as well as related legislation.

E-Filing Tax Returns: Penalty Authority and Digitizing More Paper Return Data Could Increase Benefits
A letter report issued by the Government Accountability Office with an abstract that begins "The Internal Revenue Service's (IRS) goal is to receive 80 percent of all major types of tax returns electronically by 2012. Legislation passed in November 2009 supports the 80 percent goal for individual income tax returns by requiring tax return preparers who file more than 10 individual returns per year to file them electronically, or e-file. GAO was asked to review IRS's implementation of this e-file mandate. Specifically, GAO (1) described e-file rates and preparers' experiences implementing the mandate, (2) assessed IRS's plans to enforce the mandate, (3) assessed IRS's analysis of options for digitizing more data from paper returns, and (4) determined whether there are any tax forms IRS cannot accept electronically and assessed IRS's plans for adding them to the e-file system. To conduct these analyses, GAO reviewed IRS processing data and e-file planning documents, and interviewed IRS officials and 26 members of national preparer organizations."

Information Technology: Census Bureau Needs to Improve Its Risk Management of Decennial Systems
A letter report issued by the Government Accountability Office with an abstract that begins "Automation and information technology (IT) are expected to play a critical role in the 2010 decennial census. The Census Bureau plans to spend about $3 billion on automation and technology that are to improve the accuracy and efficiency of census collection, processing, and dissemination. The Bureau is holding what it refers to as a Dress Rehearsal, during which it plans to conduct operational testing that includes the decennial systems. In view of the importance of IT acquisitions to the upcoming census, GAO was asked to (1) determine the status and plans for four key IT acquisitions, including schedule and cost, and (2) assess whether the Bureau is adequately managing associated risks. To achieve its objectives, GAO analyzed acquisition documents and the projects' risk management activities and compared these activities to industry standards."

Highlights of a Forum: Participant-Identified Leading Practices That Could Increase the Employment of Individuals with Disabilities in the Federal Workforce
Other written product issued by the Government Accountability Office with an abstract that begins "The Rehabilitation Act of 1973 (Rehabilitation Act) requires agencies to take proactive steps to provide equal opportunity to qualified individuals with disabilities, but their rate of employment with the federal government remains low. GAO was asked to identify barriers to the employment of people with disabilities in the federal workforce and leading practices that could be used to overcome these barriers. On July 20, 2010, GAO convened a forum to identify leading practices that federal agencies could implement within the current legislative context. In preparation for the forum, GAO surveyed a wide range of knowledgeable individuals to identify barriers and leading practices. Forum participants were selected from among respondents (or their representatives) to reflect varying expertise and views concerning the employment of individuals with disabilities. The survey results formed the basis for the initial forum agenda, and were refined by participants to focus on actions they deemed most important. Comments in this report do not necessarily represent the views of any individual participant or the organizations that these participants represent or with which they are affiliated, including GAO."

Financial Audit: Restated Financial Statements: Agencies' Management and Auditor Disclosures of Causes and Effects and Timely Communication to Users
A letter report issued by the Government Accountability Office with an abstract that begins "GAO continues to have concerns about restatements to federal agencies' previously issued financial statements. During fiscal year 2005, at least 7 of the 24 Chief Financial Officers (CFO) Act agencies restated certain of their fiscal year 2004 financial statements to correct misstatements. To study this trend, GAO reviewed the nature and causes of the restatements made by certain CFO Act agencies in fiscal year 2004 to their fiscal year 2003 financial statements. Eleven CFO Act agencies had restatements for fiscal year 2003. Nine of those 11 received unqualified opinions on their originally issued fiscal year 2003 financial statements. GAO's view is that users of federal agencies' financial statements and the related audit reports need to be provided at least a basic understanding of why a restatement was necessary and its effect on the agencies' previously issued financial statements and related audit reports. This report communicates GAO's observations on the transparency and timeliness of the 9 federal agencies' and their auditors' restatement disclosures."

Aviation Safety: Enhanced Oversight and Improved Availability of Risk- Based Data Could Further Improve Safety
A letter report issued by the Government Accountability Office with an abstract that begins "Takeoffs, landings, and movement around the surface areas of airports (the terminal area) are critical to the safe and efficient movement of air traffic. The nation's aviation system is arguably the safest in the world, but close calls involving aircraft or other vehicles at or near airports are common, occurring almost daily. The Federal Aviation Administration (FAA) provides oversight of the terminal area and has taken action to improve safety, but has been called upon by the National Transportation Safety Board (NTSB) and others to take additional steps to improve its oversight. As requested, this report addresses (1) recent actions FAA has taken to improve safety in the terminal area, (2) recent trends in terminal area safety and factors contributing to those trends, and (3) any additional actions FAA could take to improve safety in the terminal area. To address these issues, GAO analyzed data from FAA data; reviewed reports and FAA documents; and interviewed federal and industry officials."

Cost of Prisons: Bureau of Prisons Needs Better Data to Assess Alternatives for Acquiring Low and Minimum Security Facilities
A letter report issued by the Government Accountability Office with an abstract that begins "Over the last 10 years, the cost to confine federal Bureau of Prison (BOP) inmates in non-BOP facilities has nearly tripled from about $250 million in fiscal year 1996 to about $700 million in fiscal year 2006. Proponents of using contractors to operate prisons claim it can save money; others question whether contracting is a cost-effective alternative. In response to Conference Report 109-272, accompanying Pub. L. No. 109-108 (2005), this report discusses the feasibility and implications of comparing the costs for confining federal inmates in low and minimum security BOP facilities with those managed by private firms for BOP. GAO reviewed available data on a selection of 34 low and minimum security facilities; related laws, regulations, and documents; and interviewed BOP and contract officials."

Ryan White Care Act: Impact of Legislative Funding Proposal on Urban Areas
Correspondence issued by the Government Accountability Office with an abstract that begins "The Ryan White Comprehensive AIDS Resources Emergency Act of 1990 (CARE Act), administered by the Department of Health and Human Services' (HHS) Health Resources and Services Administration (HRSA), was enacted to address the needs of jurisdictions, health care providers, and people with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and their family members. In December 2006 the Ryan White HIV/AIDS Treatment Modernization Act of 2006 reauthorized CARE Act programs for fiscal years 2007 through 2009. In July 2007, the House of Representatives passed H.R. 3043, the Departments of Labor, Health and Human Services, and Education and Related Agencies Appropriations Act for fiscal year 2008, which contains a hold-harmless provision covering funding for urban areas that receive funding under the CARE Act. This bill has not been passed by the Senate. Under the CARE Act, funding for Eligible Metropolitan Areas (EMA) and Transitional Grant Areas (TGA) is primarily provided through three categories of grants: (1) formula grants that are awarded based on the case counts of people with HIV/AIDS living in an urban area; (2) supplemental grants that are awarded on a competitive basis based on an urban area's demonstration …

School Mental Health: Role of the Substance Abuse and Mental Health Services Administration and Factors Affecting Service Provision
Correspondence issued by the Government Accountability Office with an abstract that begins "The U.S. Surgeon General reported in 1999 that about one in five children in the United States suffers from a mental health problem that could impair their ability to function at school or in the community. Yet many children receive no mental health services. While many of the existing mental health services for children are provided in schools, the extent and manner of school mental health service delivery vary across the country and within school districts. Federally led initiatives have identified schools as a potentially promising location for beginning to address the mental health needs of children. Both the report of the Surgeon General's Conference on Children's Mental Health and the 2003 report of the President's New Freedom Commission on Mental Health--Achieving the Promise: Transforming Mental Health Care in America--identified school mental health services as a means of improving children's mental and emotional well-being. At the federal level, the Department of Health and Human Services' (HHS) Substance Abuse and Mental Health Services Administration (SAMHSA) has a stated mission of building resilience and facilitating recovery for people--including children at risk for mental health problems. Although SAMHSA is the federal …

United Nations: Management Reforms Progressing Slowly with Many Awaiting General Assembly Review
A letter report issued by the Government Accountability Office with an abstract that begins "Despite various reform efforts, significant inefficiencies in United Nations (UN) management operations persist. In September 2005, heads of UN member states approved a resolution that called for a series of reforms to strengthen the organization. As the largest financial contributor to the UN, the United States has a strong interest in the progress of UN reform initiatives. GAO was asked to (1) identify and track the status of UN management reforms in five key areas and (2) identify factors that may affect the implementation of these reform initiatives. To address these objectives, GAO reviewed documents proposing UN management reform and interviewed U.S. and UN officials."

Next Generation Air Transportation System: FAA Has Made Some Progress in Implementation, but Delays Threaten to Impact Costs and Benefits
A publication issued by the Government Accountability Office with an abstract that begins "This testimony discusses the current progress toward implementing the Next Generation Air Transportation System (NextGen). NextGen will impact nearly every aspect of air transportation and will transform the way in which the air transportation system operates today. It will do so, in part, by (1) using satellite-based surveillance as opposed to ground-based radars, (2) using performance-based navigation instead of cumbersome step-by-step procedures, (3) replacing routine voice communications with data transmissions, and (4) organizing and merging the disjointed data that pilots, controllers, airports, airlines, and others currently rely on to operate the system. The Federal Aviation Administration (FAA) has been planning and developing NextGen since 2003, and is now implementing near-term (through 2012) and mid-term (through 2018) capabilities. Over the years, concerns have been raised by the Congress and other stakeholders that despite years of effort and billions of dollars spent, FAA has not made sufficient progress in deploying systems and producing benefits. In past reports, we have made a number of recommendations to FAA to address delays in development and acquisitions, improve its processes, and focus on accountability and performance. Others have also made recommendations to FAA …

Human Capital: Preliminary Observations on the Administration's Draft Proposed "Working for America Act"
Testimony issued by the Government Accountability Office with an abstract that begins "The federal government must have the capacity to plan more strategically, react more expeditiously, and focus on achieving results. Critical to the success of this transformation are the federal government's people--its human capital. We have commended the progress that has been made in addressing human capital challenges in the last few years. Still, significant opportunities exist to improve strategic human capital management to respond to current and emerging 21st century challenges. A key question, for example, is how to update the federal government's classification and compensation systems to be more market-based and performance-oriented. The Administration's draft proposed "Working for America Act" is intended to ensure that agencies are equipped to better manage, develop, and reward their employees. Under this proposal, the Office of Personnel Management (OPM) is to design a new core classification and pay system, among other things. In addition, the draft proposal amends some provisions of Title 5 covering labor management relations and adverse actions and appeals. This testimony presents preliminary observations on the draft proposal; presents the principles, criteria, and processes for human capital reform; and suggests next steps for selected and targeted actions."

Future Years Defense Program: Risks in Operation and Maintenance and Procurement Programs
A letter report issued by the General Accounting Office with an abstract that begins "This report summarizes GAO's findings on the Department of Defense's (DOD) Future Years Defense Program (FYDP). Although total funding in the 2001 FYDP is about $16 billion more than in the 2000 FYDP, DOD may not be able to implement its operation and maintenance and procurement programs as planned. GAO identified several areas in which costs may be understated or savings overstated, increasing the risk that in the next FYDP the military will have to shift more funds to these accounts from other accounts. DOD's efforts to reduce its infrastructure costs may not yield the savings that it planned to use to fund modernization and readiness needs. Because the military services and the defense organizations have already adjusted their current budgets and future years funding projects to reflect these expected savings, they will likely experience funding shortfalls unless other adjustments are made or additional ends are provided."
