Indian Issues: The Office of the Special Trustee Has Implemented Several Key Trust Reforms Required by the 1994 Act, but Important Decisions about Its Future Remain

A letter report issued by the Government Accountability Office with an abstract that begins "The American Indian Trust Fund Management Reform Act of 1994 established the Office of the Special Trustee for American Indians (OST), within the Department of the Interior, to oversee the implementation of management reforms for funds--derived primarily from Interior's leasing of Indian lands--that Interior holds in trust for many Indian tribes and individuals. Specifically, the act directs that an integrated information system be developed that interfaces the trust fund accounting system with the land title records and asset management systems maintained by Interior's Bureau of Indian Affairs (BIA). GAO examined (1) OST's progress in implementing the trust fund management reforms and (2) the extent to which OST has used contractors in implementing these reforms. GAO reviewed OST's strategic plans and contracting documents and interviewed OST and BIA managers."

Information Technology: DOD Needs to Ensure That Navy Marine Corps Intranet Program Is Meeting Goals and Satisfying Customers

A letter report issued by the Government Accountability Office with an abstract that begins "The Navy Marine Corps Intranet (NMCI) is a 10-year, $9.3 billion information technology services program. Through a performance-based contract, the Navy is buying network (intranet), application, and other hardware and software services at a fixed price per unit (or "seat") to support about 550 sites. GAO prepared this report under the Comptroller General's authority as part of a continued effort to assist Congress and reviewed (1) whether the program is meeting its strategic goals, (2) the extent to which the contractor is meeting service level agreements, (3) whether customers are satisfied with the program, and (4) what is being done to improve customer satisfaction. To accomplish this, GAO reviewed key program and contract performance management-related plans, measures, and data and interviewed NMCI program and contractor officials, as well as NMCI customers at shipyards and air depots."

GSA Fleet: Information on the Effect of Donating Cars to YouthBuild USA and Potential Benefits to Rural Youthbuild Participants

A letter report issued by the Government Accountability Office with an abstract that begins "To assist youth who live in high poverty rural areas obtain and retain jobs, YouthBuild USA, a national nonprofit organization, has proposed providing donated used cars to selected low-income youth in rural communities. YouthBuild USA's proposed program hinges on receiving donations of used cars from the federal government's General Services Administration (GSA). This report discusses (1) the effect of donating 1 to 5 percent of selected GSA used cars on GSA's fleet vehicle sales operations, (2) what studies have shown with respect to the benefits that car ownership or access may hold for low-income individuals, and (3) what studies of selected low income car ownership programs and experiences of these programs have shown with respect to the benefits of participant car ownership. In conducting this study, GAO examined auction data from GSA, reviewed academic studies on the benefits of car access in gaining employment, and interviewed officials of six existing low income car ownership programs."

Enhancement of Spin-Polarized Electron Emission from Strain-Compensated AlInGaAs-GaAsP Superlattices (open access)

Enhancement of Spin-Polarized Electron Emission from Strain-Compensated AlInGaAs-GaAsP Superlattices

Resonance enhancement of the quantum efficiency of new polarized electron photocathodes based on a short-period strain-compensated AlInGaAs/GaAsP superlattice structure is reported. The superlattice is a part of an integrated Fabry-Perot optical cavity. We demonstrate that the Fabry-Perot resonator enhances the quantum efficiency by up to a factor 10 in the wavelength region of the main polarization maximum. The high structural quality implied by these results points to the very promising application of these photocathodes for spin-polarized electron sources.

The Evolution of Ga and As Core Levels in the Formation of Fe/GaAs(001): A High Resolution Soft X-ray Photoelectron Spectroscopic Study (open access)

The Evolution of Ga and As Core Levels in the Formation of Fe/GaAs(001): A High Resolution Soft X-ray Photoelectron Spectroscopic Study

A high resolution soft x-ray photoelectron spectroscopic study of Ga and As 3d core levels has been conducted for Fe/GaAs (001) as a function of Fe thickness. This work has provided unambiguous evidence of substrate disrupting chemical reactions induced by the Fe overlayer--a quantitative analysis of the acquired spectra indicates significantly differing behavior of Ga and As during Fe growth, and our observations have been compared with existing theoretical models. Our results demonstrate that the outdiffusing Ga and As remain largely confined to the interface region, forming a thin intermixed layer. Whereas at low coverages Fe has little influence on the underlying GaAs substrate, the onset of substrate disruption when the Fe thickness reaches 3.5 {angstrom} results in major changes in the energy distribution curves (EDCs) of both As and Ga 3d cores. Our quantitative analysis suggests the presence of two new As environments of metallic character; one bound to the interfacial region and another which, as confirmed by in-situ oxidation experiments, surface segregates and persists over a wide range of overlayer thickness. Analysis of the corresponding Ga 3d EDCs found not two, but three new environments--also metallic in nature. Two of the three are interface-resident whereas the third undergoes …

Obtaining a Record Vote on the House Floor

The House of Representatives uses two kinds of votes in which the names and positions of individual Members are recorded: (1) the recorded vote, used chiefly in Committee of the Whole, though also in order in the House, and (2) the yea and nay vote, in order only in the House proper. Both kinds together are referred to as record votes or, more informally, as “roll call votes,” and both are normally taken by electronic device. This report illustrates forms commonly used for obtaining each kind of vote.

The Velocity Field of the Local Universe From Measurements of Type Ia Supernovae (open access)

The Velocity Field of the Local Universe From Measurements of Type Ia Supernovae

We present a measurement of the velocity flow of the local universe relative to the CMB rest frame, based on the Jha, Riess & Kirshner (2007) sample of 133 low redshift type Ia supernovae. At a depth of 4500 km s{sup -1} we find a dipole amplitude of 279 {+-} 68 km s{sup -1} in the direction l = 285{sup o} {+-} 18{sup o}, b = -10{sup o} {+-} 15{sup o}, consistent with earlier measurements and with the assumption that the local velocity field is dominated by the Great Attractor region. At a larger depth of 5900 km s{sup -1} we find a shift in the dipole direction towards the Shapley concentration. We also present the first measurement of the quadrupole term in the local velocity flow at these depths. Finally, we have performed detailed studies based on N-body simulations of the expected precision with which the lowest multipoles in the velocity field can be measured out to redshifts of order 0.1. Our mock catalogues are in good agreement with current observations, and demonstrate that our results are robust with respect to assumptions about the influence of local environment on the type Ia supernova rate.

Improved Superlattices for Spin-Polarized Electron Sources (open access)

Improved Superlattices for Spin-Polarized Electron Sources

Photoemission of polarized electrons from heterostructures based on InAlGaAs/GaAs superlattices with minimum conduction-band offsets is investigated. The comparison of the excitation energy dependence of the photoemission polarization degree with the calculated spectra makes it possible to determine the polarization losses at different stages of the photoemission. A maximum polarization of P = 91% and a quantum efficiency of QE = 0.5% are close to the best results obtained for photocathodes that are based on strained semiconductor superlattices.

Technical Work Plan For: Calculation of Waste Packave and Drip Shield Response to Vibratory Ground Motion and Revision of the Seismic Consequence Abstraction

The overall objective of the work scope covered by this technical work plan (TWP) is to develop new damage abstractions for the seismic scenario class in total system performance assessment (TSPA). The new abstractions will be based on a new set of waste package and drip shield damage calculations in response to vibratory ground motion and fault displacement. The new damage calculations, which are collectively referred to as damage models in this TWP, are required to represent recent changes in waste form packaging and in the regulatory time frame. The new damage models also respond to comments from the Independent Validation Review Team (IVRT) postvalidation review of the draft TSPA model regarding performance of the drip shield and to an Additional Information Need (AIN) from the U.S. Nuclear Regulatory Commission (NRC).

Magnetic Hydrogen Atmosphere Models and the Neutron Star RX J1856.5-3754 (open access)

Magnetic Hydrogen Atmosphere Models and the Neutron Star RX J1856.5-3754

RX J1856.5-3754 is one of the brightest nearby isolated neutron stars, and considerable observational resources have been devoted to it. However, current models are unable to satisfactorily explain the data. We show that our latest models of a thin, magnetic, partially ionized hydrogen atmosphere on top of a condensed surface can fit the entire spectrum, from X-rays to optical, of RX J1856.5-3754, within the uncertainties. In our simplest model, the best-fit parameters are an interstellar column density N{sub H} {approx} 1 x 10{sup 20} cm{sup -2} and an emitting area with R{sup {infinity}} {approx} 17 km (assuming a distance to RX J1856.5-3754 of 140 pc), temperature T{sup {infinity}} {approx} 4.3 x 10{sup 5} K, gravitational redshift z{sub g} {approx} 0.22, atmospheric hydrogen column y{sub H} {approx} 1 g cm{sup -2}, and magnetic field B {approx} (3-4) x 10{sup 12} G; the values for the temperature and magnetic field indicate an effective average over the surface. We also calculate a more realistic model, which accounts for magnetic field and temperature variations over the neutron star surface as well as general relativistic effects, to determine pulsations; we find there exist viewing geometries that produce pulsations near the currently observed limits. The origin …

Identification of Aircraft Hazards (open access)

Identification of Aircraft Hazards

Aircraft hazards were determined to be potentially applicable to a repository at Yucca Mountain in ''Monitored Geological Repository External Events Hazards Screening Analysis'' (BSC 2005 [DIRS 174235], Section 6.4.1). That determination was conservatively based upon limited knowledge of flight data in the area of concern and upon crash data for aircraft of the type flying near Yucca Mountain. The purpose of this report is to identify specific aircraft hazards that may be applicable to a monitored geologic repository (MGR) at Yucca Mountain, using NUREG-0800, ''Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants'' (NRC 1987 [DIRS 103124], Section 3.5.1.6), as guidance for the inclusion or exclusion of identified aircraft hazards. The intended use of this report is to provide inputs for further screening and analysis of identified aircraft hazards based upon the criteria that apply to Category 1 and Category 2 event sequence analyses as defined in 10 CFR 63.2 [DIRS 176544] (Section 4). The scope of this report includes the evaluation of military, private, and commercial use of airspace in the 100-mile regional setting of the repository at Yucca Mountain with the potential for reducing the regional setting to a more manageable size after …
