The Federal Workforce: Observations on Protections From Discrimination and Reprisal for Whistleblowing

Testimony issued by the General Accounting Office with an abstract that begins "Federal employees who report waste, fraud, and abuse shouldn't have to fear discrimination and retaliation. Despite laws designed to protect whistleblowers, some have experienced or believed that they have experienced reprisals. Proposed legislation--the Notification and Federal Employee Antidiscrimination and Retaliation Act of 2001--would provide additional protections for federal employees and would provide important data to decisionmakers. First, the act would require agencies to report the number of discrimination and whistleblower reprisal cases. Because of a lack of data, the federal government currently doesn't have a clear picture of the volume of discrimination and whistleblowing reprisal cases involving federal employees. Such data could be a starting point for agency managers to understand the nature and scope of issues in the workplace involving reprisals and discrimination. Second, the act would make agencies and their leaders accountable for providing fair and equitable workplaces. In addition, individuals would be held accountable for their actions in cases in which discrimination has occurred. Finally, the act would require agencies to notify employees in writing of their rights and protections. This provision reinforces existing requirements that employees be notified of the rights and remedies concerning …

Commercial Fisheries: Effectiveness of Fishing Buyback Programs Can Be Improved (open access)

Commercial Fisheries: Effectiveness of Fishing Buyback Programs Can Be Improved

Testimony issued by the General Accounting Office with an abstract that begins "Fish populations in many commercial fisheries are declining, causing a growing imbalance between the number of vessels in fishing fleets and the number of fish available to catch. Federally funded fishery buyback programs are one tool available for managers to bring the number of vessels and the number of fish back into balance. Buyback programs need to be carefully designed if they are to sucessfully sustain fisheries. If buyback programs are not accompanied by other measures that reduce incentives to reenter a fishery, capacity reductions resulting from buybacks will erode. Unless a buyback program prevents it, fishermen can use previously inactive vessels or permits and reenter the buyback fishery. By themselves, the buyback programs do not address a root cause of overfishing, which is called the "race to fish." In most fisheries, fishermen have an incentive to increase their fishing capacity to catch fish before someone else does or use their existing capacity more intensely. Plans for evaluating the results of buybacks should also be considered when these programs are being designed. Measuring and evaluating results can identify important lessons that can improve the effectiveness of future buybacks. …

Former Soviet Union: U.S. Rule of Law Assistance Has Had Limited Impact and Sustainability

Testimony issued by the General Accounting Office with an abstract that begins "This testimony discusses the U.S. government's rule of law assistance efforts in the new independent states of the former Soviet Union. GAO found that these efforts have had limited impact so far, and results may not be sustainable in many cases. U.S. agencies have had some success in introducing innovative legal concepts and practices in these countries. However, the U.S. assistance has not often had a major, long-term impact on the evolution of the rule of law in these countries. In some cases, countries have not widely adopted the new concepts and practices that the United States has advocated. In other cases, continuation or expansion of the innovations depends on further funding from the U.S. or other donors. In fact, the rule of law appears to have actually deteriorated in recent years in several countries, including Russia and Ukraine, according to the data used to measure the results of U.S. development assistance in the region and a host of U.S. government and foreign officials. This testimony summarizes an April 2001 report (GAO-01-354)."

Free Trade Area of the Americas: April 2001 Meetings Set Stage for Hard Bargaining to Begin

Testimony issued by the General Accounting Office with an abstract that begins "The Free Trade of the Americas Agreement (FTAA) would eliminate tariffs and create common trade and investment rules within the 34 democratic nations of the Western Hemisphere. The trade ministers for FTAA faced an ambitious agenda at the April 2001 meetings. Accommodations reached by the ministers on controversial issues, such as labor and the environment, antidumping, and nations with small economies, allowed countries to set forth basic principles while keeping topics on the table for future resolution. As a result of the movement on these controversial issues, the trade ministers were able to set out clear objectives and deadlines to promote progress during the next 18 months of the negotiations. The trade ministers told negotiating groups to (1) eliminate material that is in dispute to the maximum extent possible; (2) develop recommendations by April 1, 2002, on the methods and ground rules for negotiation; and (3) develop, where appropriate, inventories of tariffs, nontariff barriers, subsidies, and other practices that distort trade.

Critical Infrastructure Protection: Significant Challenges in Developing Analysis, Warning, and Response Capabilities

Testimony issued by the General Accounting Office with an abstract that begins "To better protect the nation's critical computer-dependent infrastructures from computer-based attacks and disruption, the President issued a directive in 1998 that established the National Infrastructure Protection Center as a national focal point for gathering information on threats and facilitating the federal government's response to computer-based incidents. This testimony discusses the center's progress in (1) developing national capabilities for analyzing cyber threat and vulnerability data and issuing warnings, (2) enhancing its capabilities for responding to cyber attacks, and (3) developing outreach and information-sharing initiatives with government and private-sector entities. GAO found that although the center has taken some steps to develop analysis and warning capabilities, the strategic capabilities described in the presidential directive have not been achieved. By coordinating investigations and providing technical assistance the center has provided important support that has improved the Federal Bureau of Investigations' ability to investigate computer crimes. The center has also developed crisis management procedures and drafted an emergency law enforcement sector plan, which is now being reviewed by sector members. The center's information-sharing relationships are still evolving and will probably have limited effectiveness until reporting procedures and thresholds are defined and trust …

Air Traffic Control: Role of FAA's Modernization Program in Reducing Delays and Congestion

Testimony issued by the General Accounting Office with an abstract that begins "This testimony discusses the Federal Aviation Administration's (FAA) efforts to modernize the nation's air traffic control (ATC) system and its relationship to other initiatives to address the escalating crises of insufficient capacity facing the aviation industry. Specifically, GAO reviews the (1) extent of the delay and congestion problems and the contribution of the ATC system to them, (2) progress and problems encountered in FAA's ATC modernization program, and (3) importance of a continued focus on delivering ATC equipment and on human capital issues as policymakers seek to address delays and congestion. GAO found that the national airspace system (NAS) is facing significant capacity problems. Last year, more than 25 percent of nationwide flights were canceled, delayed or diverted. These actions affected 163 million passengers who, on average, were delayed almost an hour. Inefficiencies in the ATC system contribute to the delays and congestion. Modernizing equipment, along with other changes in the ATC system, is expected to help increase the capacity of NAS between 5 and 15 percent. However, improvements from FAA's modernization program have fallen short so far. Although FAA has installed new equipment to provide the necessary …

To improve federal efforts to help state and local personnel prepare for domestic terrorist attacks, H.R. 525 would create a single focal point for policy and coordination--the President's Council on Domestic Terrorism Preparedness--within the White House. The new council would include the President, several cabinet secretaries, and other selected high-level officials. H.R. 525 would (1) create an executive director position with a staff that would collaborate with other executive agencies to assess threats, (2) require the new council to develop a national strategy, (3) require the new council to analyze and review budgets, and (4) require the new council to oversee implementation among the different federal agencies. Other proposals before Congress would also create a single focal point for terrorism. Some of these proposals place the focal point in the Executive Office of the President and others place it in a lead executive agency. Both locations have advantages and disadvantages."

Flu Vaccine: Steps Are Needed to Better Prepare for Possible Future Shortages

Testimony issued by the General Accounting Office with an abstract that begins "Until the 2001 flu season, the production and distribution of influenza vaccine generally went smoothly. Last year, however, several people reported that they wanted but could not get flu shots. In addition, physicians and public health departments could not provide shots to high-risk patients in their medical offices and clinics because they had not received vaccine they ordered many months in advance, or because they were being asked to pay much higher prices for vaccine in order to get it right away. At the same time, there were reports that providers in other locations, even grocery stores and restaurants, were offering flu shots to everyone--including younger, healthier people who were not at high risk. This testimony discusses the delays in production, distribution, and pricing of the 2000-2001 flu vaccine. GAO found that manufacturing difficulties during the 2000-2001 flu season resulted in an overall delay of about six to eight weeks in shipping vaccine to most customers. This delay created an initial shortage and temporary price spikes. There is no system in place to ensure that high-risk people have priority for receiving flu shots when supply is short. Because …

Farm Loan Programs: Improvements in the Loan Portfolio but Continued Monitoring Needed

Testimony issued by the General Accounting Office with an abstract that begins "This testimony discusses the Department of Agriculture's (USDA) farm loan programs, which are run by the Farm Service Agency (FSA). GAO (1) provides an overview of the financial condition of FSA's farm loan portfolio as of September 30, 2000 and (2) explains its decision to remove the farm programs from its high-risk list. GAO found that FSA had more than $16.6 billion in outstanding farm loans as of September 30, 2000; direct loans accounted for slightly more than half of this amount and guaranteed loans for slightly less than half. Of the $16.6 billion, about $2.1 billion was owed by borrowers who were delinquent on repaying their FSA loans. Most (87 percent) of the $2.1 billion was owed on direct farm loans. Although the total amount due on the problem loans remains high, this financial position reflects improvement in FSA's direct loan portfolio in recent years as well as a continuation of a relatively healthy guaranteed loan portfolio. In January 2001, GAO removed FSA's farm loan programs from its high-risk list. Several actions taken by Congress and USDA, many of which GAO recommended, have significantly improved the operation …

Medicare: Cost Sharing Policies Problematic for Beneficiaries and Program

Testimony issued by the General Accounting Office with an abstract that begins "Medicare provides valuable and extensive health care coverage for beneficiaries. Nevertheless, significant gaps leave some beneficiaries vulnerable to sizeable financial burdens from out-of-pocket expenses. Medigap is a widely available source of supplemental coverage. This testimony discusses (1) beneficiaries' potential financial liability under Medicare's current benefit structure and cost-sharing requirements, (2) the cost of Medigap policies and the extent to which they provide additional coverage, and (3) concerns that Medigap's so-called "first dollar" coverage undermines the cost control incentives of Medicare's cost-sharing requirements. GAO found that Medicare's benefits package and cost-sharing requirements leave beneficiaries liable for high out-of-pocket costs. Medigap policies pay for some or all Medicare cost-sharing requirements but do not fully protect beneficiaries from potentially significant out-of-pocket costs such as prescription drug coverage. Medigap first-dollar coverage eliminates the ability of Medicare's cost-sharing requirements to promote prudent use of services."

Nuclear Nonproliferation: DOE's Efforts to Secure Nuclear Material and Employ Weapons Scientists in Russia

Testimony issued by the General Accounting Office with an abstract that begins "The security systems installed by the Department of Energy (DOE) are reducing the risk of theft of nuclear material in Russia, but hundreds of metric tons of nuclear material still lack improved security systems. As of February 2001, DOE had installed, at a cost of about $601 million, completed or partially completed systems that protect 192 metric tons of the 603 metric tons of nuclear material identified at risk of theft. These systems, although not as stringent as those installed in the United States, are designed to prevent individuals or small groups of criminals from stealing nuclear material. During its first two years of operation, DOE's Nuclear Cities Initiative (NCI) has had limited success. DOE estimates that the program employs about 370 people, including many weapons scientists who are primarily working on a part-time basis through research projects sponsored by the U.S. national laboratories. A disproportionate amount of the NCI program's funding has been spent in the U.S. GAO also found that DOE's NCI program lacks a plan for the future.

International Monetary Fund: Few Changes Evident in Design of New Lending Program for Poor Countries

A chapter report issued by the General Accounting Office with an abstract that begins "The effectiveness and appropriateness of the International Monetary Fund's lending programs to poor countries have been widely debated, generally centering on whether the program has improved these countries' economies. In response to some of these concerns and as part of a concerted international effort to reduce poverty, the Fund expanded the goals of its lending program to its poorest members in 1999 to include an explicit focus on poverty reduction. To underscore this focus, the Fund renamed its concessional lending program the Poverty Reduction and Frowth Facility. GAO found that although the design of the facility does not differ significantly from the Fund's previous program, some elements of the new program are emphasized more now than in the past. The one major design change--getting countries to take ownership of their macroeconomic framework--is difficult to achieve for three reasons. First, many recipient governments have limited capacity to independently analyze and effectively negotiate the macroeconomic framework, which reduces the opportunity for country-specific elements to be addressed. Second, it is difficult to effectively engage nongovernmental organizations in a dialogue on these very complex matters. Finally, a national dialogue on …

Defense Inventory: Approach for Deciding Whether to Retain or Dispose of Items Needs Improvement

A letter report issued by the General Accounting Office with an abstract that begins "As of September 1999, the Department of Defense (DOD) reported that it owned secondary inventory worth about $64 billion and that $9.4 billion of that inventory is more economical to retain than to dispose of and possibly repurchase later. This report focuses on whether DOD's economic retention decisions are sound. GAO found that military components (other than the Air Force) have developed models to help make economic retention decisions on secondary inventory. However, none of the components now use their economic retention models. Instead, they and the Air Force use ceilings to limit the amount of economic retention inventory they hold. Components have not properly documented their approaches to economic retention decisions. For example, common model factors vary and assumptions are inconsistent and out of date. In addition, DOD lacked sound analytical support for the maximum levels it now uses. As a result, the components cannot depend on their models or ceilings to determine retention inventory levels without review and improvement. They also have not reviewed their approaches annually. As a result, the Department does not have a sound basis for its approach to manage items …

GAO (1) identifies potential changes in current management processes or policies that, if made, would result in a more efficient operation and (2) evaluates various aspects of the DOD policy that allow Defense Working Capital Fund activities to carry over a 3-month level of work from one fiscal year to the next. GAO found that DOD lacks a sound analytical basis for its current 3-month carryover standard. DOD established a 3-month carryover standard for most working capital fund activity groups, although it has not done the analysis necessary to support the 3-month standard. Without a validation process, neither DOD nor congressional decisionmakers can be sure that the 3-month standard is providing activity groups with reasonable amounts of carryover to ensure a smooth transition from one fiscal year to the next or whether the carryover is excessive. In addition, carryover information currently reported under the 3-month standard is not comparable between services and is misleading to DOD and congressional decisionmakers.

A Guide to Statistical Adjustment: How it Really Works.

Congress established the Census Monitoring Board to observe and monitor all aspects of the preparation and implementation of the 2000 decennial census. After the completion of the 200 census, many thoughtful parties continue a sincere debate over the implementation of statistical adjustment as a means of increasing the accuracy of the census and for its use in redistricting and the allocation of government funds and services. On March 1, 2001, the Census Bureau's Executive Steering Committee overseeing the post-census evaluation phase, the Accuracy and Coverage Evaluation (A.C.E.), recommended against adjusting the count. Reasonable people, including leading statisticians, have reviewed the statistical adjustment methodology and have raised legitimate questions. This report attempts to put that methodology into perspective and add to what will be further debate and discussion on how all of us as shareholders can continue to work together to ensure the most accurate census possible.

Promising X-ray fluorescence tests for superconducting tunneljunction detector (open access)

Promising X-ray fluorescence tests for superconducting tunneljunction detector

Scientists in the Physical Biosciences Division of the Ernest Orlando Berkeley National Laboratory (Berkeley Lab) studying transition metals in proteins with fluorescence-detected L-edge absorption spectroscopy have found the measurements to be extremely challenging. The difficulty is that the metal centers are present in very dilute concentrations so that their weak fluorescence is often obscured by strong background signals carbon and oxygen. To solve this problem, the Berkeley group has been working with researchers from the Advanced Detector Group at the Lawrence Livermore National Laboratory on an energy-dispersive superconducting tunnel junction x-ray detector. These devices in principle have the energy resolution needed to reveal the metal signal. The most recent results with the latest version of the detector on Beamline 4.0.1-2 at the Advanced Light Source (ALS) illustrate the promise of the cryogenic detector strategy not only for this application but also for spectroscopy of other types of dilute samples. Transition-metal complexes are key elements in many biologically important processes that are catalyzed by proteins (enzymes), photosynthesis being a prime example. The changes in that occur in electronic structure throughout a catalytic cycle are the subject of much research aimed at understanding the mechanisms of these processes. L-edge x-ray spectroscopy offers …

Energy Consumption and Expenditure Projections by Population Group on the Basis on the Annual Energy Outlook 2000 Forecast.

The changes in the patterns of energy use and expenditures by population group are analyzed by using the 1993 and 1997 Residential Energy Consumption Surveys. Historically, these patterns have differed among non-Hispanic White households, non-Hispanic Black households, and Hispanic households. Patterns of energy use and expenditures are influenced by geographic and metropolitan location, the composition of housing stock, economic and demographic status, and the composition of energy use by end-use category. As a consequence, as energy-related factors change across groups, patterns of energy use and expenditures also change. Over time, with changes in the composition of these factors by population group and their variable influences on energy use, the impact on energy use and expenditures has varied across these population groups.

Experimental Evaluation of Tude Support Plate Crevice Chemistry (open access)

Experimental Evaluation of Tude Support Plate Crevice Chemistry

A test methodology for measuring temperature, impedance, pH, and electrochemical potential distributions within a sludge-packed tube support plate crevice in a laboratory test is described. The method successfully showed that there were large concentration gradients between the tube and tube support plate sides of the crevice. The testing also showed that strong bases concentrated more effectively than strong acids, and that the crevice pH, when exposed to seawater-based solutions, increased with increasing superheat and decreasing bulk concentration. The large variations in the crevice chemistry observed under heat transfer were eliminated upon shutdown. These new test data suggest that it might be beneficial to evaluate the variation in the extent of stress corrosion cracking with tube support plate elevation found in some steam generators in light of local chemistry changes, as well as the variation in tubing temperature. Because of the large crevice chemistry gradients during boiling heat transfer and their subsequent homogenization upon test shutdown, the results suggest reassessing the use of hideout return measurements and tube deposit analyses in industry to infer the crevice chemistry under heat transfer conditions.

The U.S. Department of Energy (DOE) is considering the possible recommendation of a site at Yucca Mountain, Nevada, for development as a geologic repository for the disposal of high-level radioactive waste and spent nuclear fuel. To facilitate public review and comment, in May 2001 the DOE released the Yucca Mountain Science and Engineering Report (S&ER) (DOE 2001 [DIRS 153849]), which presents technical information supporting the consideration of the possible site recommendation. The report summarizes the results of more than 20 years of scientific and engineering studies. A decision to recommend the site has not been made: the DOE has provided the S&ER and its supporting documents as an aid to the public in formulating comments on the possible recommendation. When the S&ER (DOE 2001 [DIRS 153849]) was released, the DOE acknowledged that technical and scientific analyses of the site were ongoing. Therefore, the DOE noted in the Federal Register Notice accompanying the report (66 FR 23013 [DIRS 155009], p. 2) that additional technical information would be released before the dates, locations, and times for public hearings on the possible recommendation were announced. This information includes: (1) the results of additional technical studies of a potential repository at Yucca Mountain, contained …
