Best Practices: Using Spend Analysis to Help Agencies Take a More Strategic Approach to Procurement

A letter report issued by the Government Accountability Office with an abstract that begins ""Spend analysis" is a tool that provides knowledge about who are the buyers, who are the suppliers, how much is being spent for what goods and services, and where are the opportunities to leverage buying power. Private sector companies are using spend analysis as a foundation for employing a strategic approach to procurement. Recognizing the potential in government purchasing, GAO examined if the departments of Agriculture, Health and Human Services (HHS), Justice, Transportation, and Veterans Affairs are using spend analysis to take a strategic approach. GAO assessed (1) if agencies use spend analysis to obtain knowledge to improve procurement of goods and services and (2) how agencies' practices compare to leading companies best practices."

Food Stamp Program: Farm Bill Options Ease Administrative Burden, but Opportunities Exist to Streamline Participant Reporting Rules among Programs

A letter report issued by the Government Accountability Office with an abstract that begins "Many individuals familiar with the Food Stamp Program view its rules as unnecessarily complex, creating an administrative burden for participants and caseworkers. In addition many participants receive benefits from other programs that have different program rules, adding to the complexity of accurately determining program benefits and eligibility. The 2002 Farm Bill introduced new options to help simplify the program. This report examines (1) which options states have chosen to implement and why, and (2) what changes local officials reported as a result of using these options. Selected results from GAO's web-based survey of food stamp administrators are provided in an e-supplement to this report, GAO-04-1058SP. Another e-supplement, GAO-04-1059SP, contains results from the local food stamp office surveys."

Food Stamp Farm Bill Options: Local Survey Results, an E-supplement to GAO-04-916

Other written product issued by the Government Accountability Office with an abstract that begins "This document is a companion product to GAO-04-916. This document presents the results of GAO's surveys of local food stamp office supervisors. The purpose of the surveys was to determine the views of local food stamp supervisors on whether implementation of the options had achieved expected results. We developed eight surveys, one for each of the Farm Bill options, to obtain this information. We mailed out a total of 1,328 surveys to eight random samples of local food stamp office supervisors. Each of the eight samples comprised local food stamp offices in states that had implemented that option. The response rates varied between 74.0 percent and 86.1 percent. A more detailed discussion of our scope and methodology and a discussion of the summary of selected survey results are contained in our report entitled Food Stamp Program: Farm Bill Options Ease Administrative Burden, but Opportunities Exist to Streamline Participant Reporting Rules among Programs (GAO-04-916, Washington, D.C.: September 21, 2004). While this e-supplement contains information on the results from local food stamp offices, another e-supplement (GAO-04-1058SP) contains information on the results from our survey of food stamp administrators. …

Drift Degradation Analysis (open access)

Drift Degradation Analysis

Degradation of underground openings as a function of time is a natural and expected occurrence for any subsurface excavation. Over time, changes occur to both the stress condition and the strength of the rock mass due to several interacting factors. Once the factors contributing to degradation are characterized, the effects of drift degradation can typically be mitigated through appropriate design and maintenance of the ground support system. However, for the emplacement drifts of the geologic repository at Yucca Mountain, it is necessary to characterize drift degradation over a 10,000-year period, which is well beyond the functional period of the ground support system. This document provides an analysis of the amount of drift degradation anticipated in repository emplacement drifts for discrete events and time increments extending throughout the 10,000-year regulatory period for postclosure performance. This revision of the drift degradation analysis was developed to support the license application and fulfill specific agreement items between the U.S. Nuclear Regulatory Commission (NRC) and the U.S. Department of Energy (DOE). The earlier versions of ''Drift Degradation Analysis'' (BSC 2001 [DIRS 156304]) relied primarily on the DRKBA numerical code, which provides for a probabilistic key-block assessment based on realistic fracture patterns determined from field mapping …

Gamma-Ray Holdup Measurements of U-235, Np-237, and Am-241 Content in the C and D Out-gassing Ovens in the Deactivation and Decommissioning Activities in 321-M (open access)

Gamma-Ray Holdup Measurements of U-235, Np-237, and Am-241 Content in the C and D Out-gassing Ovens in the Deactivation and Decommissioning Activities in 321-M

The Analytical Development Section of Savannah River National Laboratory (SRNL) was requested by the Facilities Disposition Projects (FDP) to determine the holdup of enriched uranium in the 321-M facility as part of an overall deactivation project of the facility. The 321-M facility was used to fabricate enriched uranium fuel assemblies, lithium-aluminum target tubes, neptunium assemblies, and miscellaneous components for the production reactors. The results of the holdup assays are essential for determining compliance with the Waste Acceptance Criteria, Material Control and Accountability, and to meet criticality safety controls. This report covers holdup measurements in the C and D out-gassing ovens that were used to remove gas entrained in billet assembly material prior to the billets being extruded into rods by the extrusion press. A portable high purity germanium (HPGe) detection system and a portable sodium iodide (NaI) detection system were used to determine highly enriched uranium (HEU) holdup and to determine holdup of Np-237 and Am-241 that were observed in these components. The HPGe detector was run by an EG and G Dart (TM) system that contains the high voltage power supply and signal processing electronics. A personal computer with Gamma-Vision software was used to control the Dart (TM) MCA …

General Corrosion and Localized Corrosion of the Drip Shield (open access)

General Corrosion and Localized Corrosion of the Drip Shield

The repository design includes a drip shield (BSC 2004 [DIRS 168489]) that provides protection for the waste package both as a barrier to seepage water contact and a physical barrier to potential rockfall. The purpose of the process-level models developed in this report is to model dry oxidation, general corrosion, and localized corrosion of the drip shield plate material, which is made of Ti Grade 7. This document is prepared according to ''Technical Work Plan For: Regulatory Integration Modeling and Analysis of the Waste Form and Waste Package'' (BSC 2004 [DIRS 171583]). The models developed in this report are used by the waste package degradation analyses for TSPA-LA and serve as a basis to determine the performance of the drip shield. The drip shield may suffer from other forms of failure such as the hydrogen induced cracking (HIC) or stress corrosion cracking (SCC), or both. Stress corrosion cracking of the drip shield material is discussed in ''Stress Corrosion Cracking of the Drip Shield, the Waste Package Outer Barrier, and the Stainless Steel Structural Material'' (BSC 2004 [DIRS 169985]). Hydrogen induced cracking of the drip shield material is discussed in ''Hydrogen Induced Cracking of Drip Shield'' (BSC 2004 [DIRS 169847]).

Layzer type models for pressure driven shells

Models for the nonlinear instability of finite thickness shells driven by pressure are constructed in the style of Layzer. Equations for both Cartesian and cylindrically convergent/divergent geometries are derived. The resulting equations are appropriate for incompressible shells with unity Atwood number. Predictions from the equations compare well with two-dimensional simulations.

Bounds and self-consistent estimates for elastic constants of random polycrystals with hexagonal, trigonal, and tetragonal symmetries (open access)

Bounds and self-consistent estimates for elastic constants of random polycrystals with hexagonal, trigonal, and tetragonal symmetries

Peselnick, Meister, and Watt have developed rigorous methods for bounding elastic constants of random polycrystals based on the Hashin-Shtrikman variational principles. In particular, a fairly complex set of equations that amounts to an algorithm has been presented previously for finding the bounds on effective elastic moduli for polycrystals having hexagonal, trigonal, and tetragonal symmetries. The more analytical approach developed here, although based on the same ideas, results in a new set of compact formulas for all the cases considered. Once these formulas have been established, it is then straightforward to perform what could be considered an analytic continuation of the formulas (into the region of parameter space between the bounds) that can subsequently be used to provide self-consistent estimates for the elastic constants in all cases. These self-consistent estimates are easily shown (essentially by construction) to lie within the bounds for all the choices of crystal symmetry considered. Estimates obtained this way are quite comparable to those found by the Gubernatis and Krumhansl CPA (coherent potential approximation), but do not require any computations of scattering coefficients.

An Analytical Model for Solute Transport in Unsaturated Flowthrough a Single Fracture and Porous Rock Matrix (open access)

An Analytical Model for Solute Transport in Unsaturated Flowthrough a Single Fracture and Porous Rock Matrix

Exact analytical solutions are presented for solute transport in an unsaturated fracture and porous rock matrix. The problem includes advective transport in the fracture and rock matrix as well as advective and diffusive fracture-matrix exchange. Linear sorption in the fracture and matrix and radioactive decay are also treated. The solution is for steady, uniform transport velocities within the fracture and matrix, but allows for independent specification of each of the velocities. The problem is first solved in terms of the solute concentrations that result from an instantaneous point source. Superposition integrals are then used to derive the solute mass flux at a fixed downstream position from an instantaneous point source and for the solute concentrations that result from a continuous point source. Solutions are derived for cases with the solute source in the fracture and the solute source in the matrix. The analytical solutions are closed-form and are expressed in terms of algebraic functions, exponentials, and error functions. Comparisons between the analytical solutions and numerical simulations, as well as sensitivity studies, are presented. Increased sensitivity to cross-flow and solute source location is found for increasing Peclet number. The numerical solutions are found to compare well with the analytical solutions at …

"Spam": An Overview of Issues Concerning Commercial Electronic Mail

Spam, also called unsolicited commercial email (UCE) or “junk email,” aggravates many computer users. Not only can spam be a nuisance, but its cost may be passed on to consumers through higher charges from Internet service providers who must upgrade their systems to handle the traffic. Also, some spam involves fraud, or includes adult-oriented material that offends recipients or that parents want to protect their children from seeing. Proponents of UCE insist it is a legitimate marketing technique that is protected by the First Amendment, and that some consumers want to receive such solicitations. This report discusses this issue in detail, as well as related legislation.

Exempting Food and Agriculture Products from U.S. Economic Sanctions: Status and Implementation (open access)

Exempting Food and Agriculture Products from U.S. Economic Sanctions: Status and Implementation

Falling agricultural exports and declining commodity prices led farm groups and agribusiness firms to urge the 106th Congress to pass legislation exempting foods and agricultural commodities from U.S. economic sanctions against certain countries. In completing action on the FY2001 agriculture appropriations bill, Congress codified the lifting of unilateral sanctions on commercial sales of food, agricultural commodities, medicine, and medical products to Iran, Libya, North Korea, and Sudan, and extended this policy to apply to Cuba (Title IX of H.R. 5426, as enacted by P.L. 106-387; Trade Sanctions Reform and Export Enhancement Act of 2000). Related provisions place financing and licensing conditions on sales to these countries. Those that apply to Cuba, though, are permanent and more restrictive than for the other countries. Other provisions give Congress the authority in the future to veto a President's proposal to impose a sanction on the sale of agricultural or medical products.

Average Farm Subsidy Payments, by State, 2002 (open access)

Average Farm Subsidy Payments, by State, 2002

The U.S. Department of Agriculture makes direct subsidy payments through the Commodity Credit Corporation to farmers for commodity price and income support, certain conservation and environmental activities, and some disaster losses. In 2002, these direct farm subsidy payments amounted to $12.151 billion. This report examines the distribution of these payments among states, calculates the average size of payments going to recipient farms in each state, and distinguishes between payments received by farm operators and landlords. This information is intended to aid in policy debates about subsidizing some farms but not others, changing per-person payment limits, and the altering eligibility rules for landlords to receive payments.
