USDA Graduate School: Revenue Reporting Needs to Be Improved (open access)

USDA Graduate School: Revenue Reporting Needs to Be Improved

A letter report issued by the General Accounting Office with an abstract that begins "The U.S. Department of Agriculture's Graduate School provides extensive training opportunities to government employees and others. As a nonappropriated fund instrumentality, the Graduate School relies solely on income from the training it offers. During fiscal year 1999, the federal agencies GAO reviewed had 20 interagency agreements with the Graduate School totaling about $5.7 million. The agencies also had 531 contracts, totaling $29 million, with private companies for training and related services. The Graduate School's financial statements for fiscal year 1999 incorrectly identified the portion of revenue that was earned through interagency agreements. This misclassification occurred primarily because of the Graduate School's reporting policies."

Financial Management: FFMIA Implementation Critical for Federal Accountability (open access)

Financial Management: FFMIA Implementation Critical for Federal Accountability

A letter report issued by the General Accounting Office with an abstract that begins "Effective management of the government's day-to-day operations has been hampered by a lack of necessary data. The Chief Financial Officers (CFO) Act of 1990 calls for the modernization of federal financial management systems, including the systematic measurement of performance; the development of cost information; and the integration of program, budget, and financial information. The Federal Financial Management Improvement Act of 1996 (FFMIA) encourages agencies to have systems that generate timely, accurate, and useful information with which to make informed decisions and to ensure accountability on an ongoing basis. Auditors for 19 of the 24 CFO Act agencies reported that their agencies' financial management systems did not comply substantially with FFMIA requirements, compared to 21 agencies reported as not being substantially compliant for 1999. The auditors for five CFO Act agencies reported no instances in which the agencies' systems did not substantially comply with FFMIA. These auditors, however, did not definitively state whether the agencies' financial management systems substantially complied with FFMIA. FFMIA requires agencies to prepare remediation plans to overcome financial management systems problems. These plans have improved over the fiscal year 1998 plans; however, further …

Elections: Statistical Analysis of Factors That Affected Uncounted Votes in the 2000 Presidential Election (open access)

Elections: Statistical Analysis of Factors That Affected Uncounted Votes in the 2000 Presidential Election

A letter report issued by the General Accounting Office with an abstract that begins "Following the 2000 presidential election, concerns were raised about the election process, including the ability of some voting equipment to render a complete and accurate vote count. Furthermore, minorities and disadvantaged voters were seen as more likely to have their votes not counted because they may have used less reliable voting equipment than affluent white voters. GAO found that although the state in which counties are located had more of an effect on the number of uncounted presidential votes than did counties' demographic characteristics or voting equipment, there were statistically significant effects on uncounted presidential votes. State differences accounted for 26 percent of the total variation in uncounted presidential votes across counties. State differences may have included such factors as statewide voter education efforts, state standards for determining what is a valid vote, the use of straight party ballots, the number of candidates on the ballot, the use of provisional ballots, and the extent to which absentee or early voting occurred."

Private Health Insurance: Small Employers Continue to Face Challenges in Providing Coverage (open access)

Private Health Insurance: Small Employers Continue to Face Challenges in Providing Coverage

A letter report issued by the General Accounting Office with an abstract that begins "Many small employers--those with 50 or fewer workers--do not offer health benefits to their employees. This is particularly true for employers with fewer than 10 workers. The families of workers employed by small employers are about twice as likely to be uninsured as households with a worker at a large employer. Despite efforts by Congress and the states to help small employers buy coverage, many small employers continue to cite cost as a major obstacle to providing coverage. Small and large employers purchasing health insurance generally had comparable premiums in 1998, but this comparison does not fully reflect the challenges facing small employers in providing health insurance for their employees. Although the premiums were similar, the health plans offered by small employers were slightly less generous on average--they had slightly higher average cost-sharing requirements for their employees and were somewhat less likely to offer some benefits, excluding, for example, mental health services and chiropractic care. Also, insurers' costs to administer employer-based health insurance and protect against potentially large health care costs result in a larger share of small employers' premium dollars being spent on these nonbenefit …

Information Sharing: Practices That Can Benefit Critical Infrastructure Protection (open access)

Information Sharing: Practices That Can Benefit Critical Infrastructure Protection

A letter report issued by the General Accounting Office with an abstract that begins "Information sharing and coordination are key elements in any defense against cyber attacks. The organizations GAO reviewed identified factors they considered critical to their success in building successful information-sharing relationships with and among their members. All of the organizations identified trust as essential to successful relationships. They said that trust could only be built over time and through personal relationships. One of the most difficult challenges identified was the initial reluctance of new members to share information. Other challenges included (1) developing agreements on the use and protection of shared information, (2) obtaining adequate funding for websites and meetings while avoiding contributions intended primarily to promote the interests of an individual organization, (3) maintaining a focus on emerging issues of interest to members, and (4) maintaining appropriately skilled professional and administrative staff."

Electronic Commerce: Small Business Participation in Selected On-line Procurement Programs (open access)

Electronic Commerce: Small Business Participation in Selected On-line Procurement Programs

A letter report issued by the General Accounting Office with an abstract that begins "The federal government has been pursuing electronic initiatives to strengthen its buying processes, reduce costs, and create a competitive "virtual" marketplace. Small businesses, however, may have difficulty participating in federal on-line procurement programs. Furthermore, the government's business outreach and education programs related to electronic commerce may not be adequately coordinated. For the three federal on-line procurement programs GAO reviewed, the dollar share of awards to small businesses exceeded the overall small business share of total federal contract dollars awarded in fiscal years 2000 and 1999. Although small businesses successfully participated in these three programs, they still face obstacles in conducting electronic procurements with the government. The federal government is taking steps to address some of these obstacles, such as implementing a single point of entry on the Internet for vendors to access information on available government business opportunities greater than $25,000. Each of the four business assistance programs GAO examined had taken steps to educate its clients on electronic commerce as part of its operations. However, GAO could not fully determine the extent of these activities because they are conducted by hundreds of local and regional …

Medicare Physician Fee Schedule: Practice Expense Payments to Oncologists Indicate Need For Overall Refinements (open access)

Medicare Physician Fee Schedule: Practice Expense Payments to Oncologists Indicate Need For Overall Refinements

A letter report issued by the General Accounting Office with an abstract that begins "Medicare's physician fee schedule establishes payments for more than 7,000 different services, such as office visits, surgical procedures, and treatments. Before 1992, fees were based on charges physicians billed for these services. Since then, the Health Care Financing Administration (HCFA), which runs Medicare, has been phasing in a new fee schedule on the basis of the amount of resources used to provide that service relative to other services. The development of the resource-based practice expense component was a substantial undertaking. The implementation of the resource-based methodology has been the subject of considerable controversy, partly because of HCFA's adjustments to the underlying data and basic method and partly because payment changes were required to be budget-neutral--which means that total Medicare spending for physician services was to be the same under the new payment method as it was under the old one. As a result, Medicare payments to some specialties have increased while payments to other specialties have decreased. Oncologists claim that their practice expense payments are particularly inadequate for some office-based services, such as chemotherapy. Oncology practice expense payments in 2001 are eight percent higher than they …

Joint Strike Fighter Acquisition: Mature Critical Technologies Needed to Reduce Risks

A letter report issued by the General Accounting Office with an abstract that begins "The Joint Strike Fighter Program (JSFP), the military's most expensive aircraft program, is intended to produce affordable, next-generation aircraft to replace aging aircraft in military inventories. Although JSFP has made good progress in some technology areas, the program may not meet its affordability objective because critical technologies are not projected to be matured to levels GAO believes would indicate a low risk program at the planned start of engineering and manufacturing development in October 2001."

Financial Management: Assessment of the Airline Industry's Estimated Losses Arising From the Events of September 11

Correspondence issued by the General Accounting Office with an abstract that begins "The airline industry's losses from the terrorist attacks will total at least $5 billion through December 2001. Even so, carrier-by-carrier losses are likely to vary significantly from the formula-derived allocations of $5 billion. Therefore, some carriers may experience losses higher than their individual formula amount, while others' losses may be lower."

Correspondence issued by the General Accounting Office with an abstract that begins "The Haitian Refugee Immigration Fairness Act of 1998 allows Haitian nationals and their dependents to apply to adjust their status to legal permanent residence. The act requires the Comptroller General to report every six months on the number of Haitian nationals who have applied and been approved for legal permanent residence status. GAO found that, as of September 30, 2001, the Immigration and Naturalization Service had received 35,946 applications and had approved 5,072 of them. The Executive Office for Immigration Review had 107 applications filed and had approved 87 of them."

Health Care: Adequacy of Pharmacy, Laboratory, and Radiology Workforce Supply Difficult to Determine

Correspondence issued by the General Accounting Office with an abstract that begins "Concerns have been growing about the supply of health care workers and the future needs of an aging population. Shortages of nurses and nurse aides, the two largest categories of health care workers, are of particular concern. Although the number of pharmacists has grown during the past decade, the increasing demand for pharmacy services is outpacing the growth in supply, according to the Department of Health and Human Services. Provider and professional associations have reported high vacancy rates and a decline in new entrants to the laboratory and radiologic fields. However, employment and earnings data for laboratory and radiologic technologists and technicians do not indicate a balance of supply and demand for these workers. Demographic changes, technological advances, and management decisions on how staff and technology are used will affect the future demand for health care workers."

VA and Defense Health Care: Progress and Challenges DOD Faces in Executing a Military Medical Surveillance System

A statement of record issued by the General Accounting Office with an abstract that begins "The Departments of Defense (DOD) and Veterans Affairs (VA) are establishing a medical surveillance system for the health care needs of military personnel and veterans. The system will collect and analyze information on deployments, environmental health threats, disease monitoring, medical assessments, and medical encounters. GAO has identified weaknesses in DOD's medical surveillance capability and performance during the Gulf War and Operation Joint Endeavor. Investigations into the unexplained illnesses of Gulf War veterans uncovered many deficiencies in DOD's ability to collect, maintain, and transfer accurate data on the movement of troops, potential exposures to health risks, and medical incidents during deployment. DOD has several initiatives under way to improve the reliability of deployment information and to enhance its information technology capabilities, though some initiatives are several years away from full implementation. The VA's ability to serve veterans and provide backup to DOD in times of war will be enhanced as DOD increases its medical surveillance capability."

Strategies to Manage Improper Payments: Learning From Public and Private Sector Organizations (Supersedes GAO-01-703G)

Guidance issued by the General Accounting Office with an abstract that begins "This publication supersedes GAO-01-703G, Strategies to Manage Improper Payments: Learning From Public and Private Sector Organizations (Exposure Draft), May 2001. Improper payments are a significant problem in both government and the private sector. In the private sector, improper payments are generally an internal problem that threatens profitability. In the public sector, improper payments can result in wasteful spending, a higher tax burden, and fewer people receiving services. Despite increased scrutiny, most improper payments associated with federal programs still go undetected. Improper payments are more likely in programs with complex criteria for computing payments, a high volume of transactions, or an emphasis on speedy payments. This report highlights strategic actions taken by study participants to reduce improper payments."

Investigative Techniques: Federal Agency Views on the Potential Application of 'Brain Fingerprinting' (open access)

Investigative Techniques: Federal Agency Views on the Potential Application of 'Brain Fingerprinting'

A letter report issued by the General Accounting Office with an abstract that begins "Federal law enforcement and intelligence agencies are seeking to add new techniques to their arsenal of investigative tools. "Brain fingerprinting" measures brain wave responses to determine whether an individual recognizes certain details of an event or activity. Because the technique requires specific information about the event that would be known only to the perpetrator and the investigator, Brain Fingerprinting is not designed as a screening tool--a function that involves questioning a subject about events unknown to the investigator. Instead, an investigator would be able to use certain information as evidence for or against a subject. For example, the technique could be used to determine whether a subject has knowledge of details about a crime. Officials representing the Central Intelligence Agency, the Department of Defense, the Secret Service, and the Federal Bureau of Investigation do not forsee using the brain fingerprinting technique because of its limited use. Furthermore, given the technique's limitations, the research expenses, equipment, and training costs are perceived to exceed benefits."

Voters With Disabilities: Access to Polling Places and Alternative Voting Methods

A letter report issued by the General Accounting Office with an abstract that begins "Federal law requires that disabled persons have access to polling places on election day. State political subdivisions must ensure that polling places used in federal elections are accessible. Exceptions are allowed if all potential polling places have been surveyed, no accessible place is available, and the political subdivision cannot make one temporarily accessible. In these cases, disabled voters must either be reassigned to an accessible polling place or provided another means for voting on election day. All states have provisions that address voting by people with disabilities, but these provisions vary greatly. All states provide for one or more alternative voting methods or accommodations that may facilitate voting by people with disabilities. States and localities have made several efforts to improve voting accessibility for the disabled, such as modifying poling places, acquiring new voting equipment, and expanding voting options. Nevertheless, state and county election officials GAO surveyed cited various challenges to improving access."

Physical Infrastructure: Crosscutting Issues Planning Conference Report

A staff study issued by the General Accounting Office with an abstract that begins "The nation's physical infrastructure consists of a broad array of systems and facilities, including transportation networks, such as roads, airports, rail, and mass transit; housing; federal buildings including postal facilities; and telecommunications services. In the 21st century, the following trends are likely to influence the nation's need for interconnected infrastructure systems and services: (1) the total population of the United States is expected to increase by nearly 50 million people, or about 17 percent; (2) the number of Americans aged 55 and over is expected to increase by about 60 percent; and (3) the suburbanization of population and employment will continue. The steps that the nation takes to anticipate these trends in infrastructure policy and investments will have a direct effect on America's economy and quality of life. To better understand these connections, GAO sponsored a conference in June 2001 to consider infrastructure issues from a crosscutting perspective. This report discusses the findings and conclusions of that conference."
