U.S. Commission on Civil Rights: The Commission Should Strengthen Its Quality Assurance Policies and Make Better Use of Its State Advisory Committees

A letter report issued by the Government Accountability Office with an abstract that begins "The U.S. Commission on Civil Rights (the Commission) was established by the Civil Rights Act of 1957 to serve as an independent, bipartisan, fact-finding agency whose mission is to investigate and report on the status of civil rights in the United States. Since its inception, the Commission has conducted hearings and issued reports highlighting critical, controversial civil rights issues, including racial segregation, impediments to voting rights, and affirmative action. To carry out its fact-finding and reporting mission, the Commission is required to submit at least one report annually to the President and Congress on federal civil rights enforcement efforts, among other requirements. Because the Commission has no enforcement power, the key means for achieving its mission lies in its credibility as an independent and impartial fact-finding and reporting organization. To complement this national fact-finding and reporting effort, separate state advisory committees were also authorized in 1957 to advise the Commission and serve as its "eyes and ears" on state and local civil rights issues. State advisory committees are composed of volunteers appointed by the Commission in every state who conduct public hearings on state and local …

Military Personnel: Military Departments Need to Ensure That Full Costs of Converting Military Health Care Positions to Civilian Positions Are Reported to Congress

A letter report issued by the Government Accountability Office with an abstract that begins "Based on studies showing that many military members are performing tasks that are not considered military essential, the Air Force, Army, and Navy have plans to convert certain numbers of military health care positions to civilian positions. Questions have surfaced regarding the potential effects of these conversions on the Defense Health Program. The National Defense Authorization Act for Fiscal Year 2006 prohibits the military departments from performing any further conversions until the secretary of each department certifies to Congress that the conversions will not increase costs or decrease quality or access to care. The act also requires GAO to study the military departments' conversions and their potential effects. Specifically, GAO examined (1) the military departments' plans for and actions to date in converting military health care positions to civilian positions and the departments' experiences in filling the converted positions with civilians and (2) the potential effects of converting military health care positions to civilian positions on the Defense Health Program."

Defense Health Care: Health Care Benefit for Women Comparable to Other Plans (open access)

Defense Health Care: Health Care Benefit for Women Comparable to Other Plans

A letter report issued by the General Accounting Office with an abstract that begins "Half of all beneficiaries in the Department of Defense's (DOD) Tricare health care program are women. With a health care system historically oriented towards men, DOD has had to work to ensure that its women beneficiaries receive the full range of medical services they are entitled to, including obstetrical and gynecological care and diagnostic services such as Pap smears and mammograms. TRICARE-covered benefits are in line with American College of Obstetricians and Gynecologists guidelines and are comparable to women's health benefits offered by two of the largest health plans under the Federal Employees Health Benefits Program (FEHBP). DOD also requires some beneficiaries to share in the cost of their health care. Both DOD's and FEHBP's copayments, which are the same for men and women, vary depending on the plan option and the providers selected. Women beneficiaries report being satisfied with the health care benefits they receive under TRICARE. Some women beneficiaries, however, have expressed concerns about obtaining services when they are stationed overseas or in remote areas. Some active duty women are also concerned that command personnel may not understand women's health care needs."

Forum on Key National Indicators: Assessing the Nation's Position and Progress

A letter report issued by the General Accounting Office with an abstract that begins "The nation confronts profound challenges resulting from a variety of factors, including changing security threats, dramatic shifts in demographic patterns, the multidimensional processes of globalization, and the accelerating pace of technological change. These are all coming together in an era of diminishing public resources. The nation's leaders and concerned citizens require better knowledge of what is happening and where we are going to support improved public choices. The United States could potentially benefit from developing a set of key national indicators to help assess our nation's position and progress. On February 27, 2003, GAO, in cooperation with the National Academies, hosted a forum on key national indicators. The purpose of the forum was to have a rich and meaningful dialogue on whether and how to develop a set of key national indicators for the United States. The forum brought together a diverse group of national leaders to discuss the following: How are the world's leading democracies measuring national performance? What might the United States do to improve its approach and why? What are important areas to measure in assessing U.S. national performance? How might new U.S. …

Retiree Health Benefits: Employer-Sponsored Benefits May Be Vulnerable to Further Erosion (open access)

Retiree Health Benefits: Employer-Sponsored Benefits May Be Vulnerable to Further Erosion

A letter report issued by the General Accounting Office with an abstract that begins "In 1999, nearly 10 million retired people aged 55 or older relied on employer-sponsored health insurance as either their primary source of coverage or as a supplement to their Medicare coverage. Some of these persons are concerned about the continued availability of employer-sponsored coverage. Premium increases and forecasts for a potential economic slowdown could further erode employer-sponsored benefits. In the long term, these factors, coupled with the potential for Medicare reforms and the rising number of aging baby boomers, may produce even more uncertainty and cost pressures for employers. Consequently, as an increasing number of retirees lack employer-based coverage, those in poorer health may have difficulty finding affordable alternative health coverage."

Transportation Security Research: Coordination Needed in Selecting and Implementing Infrastructure Vulnerability Assessments

A letter report issued by the General Accounting Office with an abstract that begins "The events of September 11, 2001, increased attention on efforts to assess the vulnerabilities of the nation's transportation infrastructure and develop needed improvements in security. The Department of Transportation's (DOT) Research and Special Programs Administration (RSPA) had already begun research in this area in June 2001. The goals of RSPA's Transportation Infrastructure Assurance program are to identify, and develop ways to mitigate the impact of, threats to the nation's transportation infrastructure. DOT's Office of Intelligence and Security is responsible for defining the requirements for transportation infrastructure protection, ensuring that vulnerability assessments of transportation infrastructure are conducted, and taking action to mitigate those vulnerabilities. The House Committee on Appropriations asked GAO to determine (1) the status and anticipated results of the Transportation Infrastructure Assurance (TIA) program, and (2) the extent to which RSPA and the Office of Intelligence and Security have coordinated their activities in selecting the vulnerabilities to be assessed and implementing the vulnerability assessments for the program. DOT and RSPA officials reviewed a draft of the report, agreed with its contents, and provided technical clarifications that we incorporated."

Control of a high beta maneuvering reentry vehicle using dynamic inversion. (open access)

Control of a high beta maneuvering reentry vehicle using dynamic inversion.

The design of flight control systems for high performance maneuvering reentry vehicles presents a significant challenge to the control systems designer. These vehicles typically have a much higher ballistic coefficient than crewed vehicles like as the Space Shuttle or proposed crew return vehicles such as the X-38. Moreover, the missions of high performance vehicles usually require a steeper reentry flight path angle, followed by a pull-out into level flight. These vehicles then must transit the entire atmosphere and robustly perform the maneuvers required for the mission. The vehicles must also be flown with small static margins in order to perform the required maneuvers, which can result in highly nonlinear aerodynamic characteristics that frequently transition from being aerodynamically stable to unstable as angle of attack increases. The control system design technique of dynamic inversion has been applied successfully to both high performance aircraft and low beta reentry vehicles. The objective of this study was to explore the application of this technique to high performance maneuvering reentry vehicles, including the basic derivation of the dynamic inversion technique, followed by the extension of that technique to the use of tabular trim aerodynamic models in the controller. The dynamic inversion equations are developed for …

Final Report on Control Algorithm to Improve the Partial-Load Efficiency of Surface PM Machines with Fractional-Slot Concentrated Windings (open access)

Final Report on Control Algorithm to Improve the Partial-Load Efficiency of Surface PM Machines with Fractional-Slot Concentrated Windings

Surface permanent magnet (SPM) synchronous machines using fractional-slot concentrated windings are being investigated as candidates for high-performance traction machines for automotive electric propulsion systems. It has been shown analytically and experimentally that such designs can achieve very wide constant-power speed ratios (CPSR) [1,2]. This work has shown that machines of this type are capable of achieving very low cogging torque amplitudes as well as significantly increasing the machine power density [3-5] compared to SPM machines using conventional distributed windings. High efficiency can be achieved in this class of SPM machine by making special efforts to suppress the eddy-current losses in the magnets [6-8], accompanied by efforts to minimize the iron losses in the rotor and stator cores. Considerable attention has traditionally been devoted to maximizing the full-load efficiency of traction machines at their rated operating points and along their maximum-power vs. speed envelopes for higher speeds [9,10]. For example, on-line control approaches have been presented for maximizing the full-load efficiency of PM synchronous machines, including the use of negative d-axis stator current to reduce the core losses [11,12]. However, another important performance specification for electric traction applications is the machine's efficiency at partial loads. Partial-load efficiency is particularly important if …

Habitat Evaluation Procedures (HEP) Report : Ladd Marsh Wildlife Area, 2004-2006 Technical Report.

The Regional HEP Team (RHT) and Oregon Department of Fish and Wildlife (ODFW) staff conducted a follow-up habitat evaluation procedures (HEP) analysis on the Ladd Marsh Wildlife Management Area (LMWA) in May 2005. The 2005 HEP assessment resulted in a total of 647.44 HUs, or 0.76 HUs/acre. This is an increase of 420.34 HUs (0.49 HUs/acre) over 2001 HEP survey results. The most significant increase in HUs occurred on the Wallender and Simonis parcels which increased by 214.30 HUs and 177.49 HUs respectively. Transects were established at or near 2001 HEP analysis transect locations whenever possible. ODFW staff biologists assisted the RHT re-establish transect locations and/or suggested areas for new surveys. Since 2001, significant changes in cover type acreage and/or structural conditions have occurred due to conversion of agriculture cover types to emergent wetland and grassland cover types. Agricultural lands were seeded to reestablish grasslands and wetlands were restored through active management and manipulation of extant water sources including natural stream hydrology/flood regimes and available irrigation. Grasslands increased on the Wallender parcel by 21% (65 acres), 23% (71 acres) at the Simonis site, and 39% (62 acres) at Conley Lake. The emergent wetland cover type also changed significantly increasing 60% …

RHIC RF Harmonic Numbers for Low Energy Operations (open access)

RHIC RF Harmonic Numbers for Low Energy Operations

There have been several test runs of RHIC operations to explore the feasibility of luminosity production at low energies. There is considerable international interest in the possible existence of a QCD phase diagram critical point in the RHIC gold-gold collision energy range of {radical}s{sub NN} = 5-50 GeV[l, 2, 3]. This paper reviews the RF harmonic number constraints for RHIC gold-gold collisions in this energy range, and concludes that optimal simultaneous collisions at both experiments are only feasible when the harmonic number is divisible by 9.
