A first simulation study of the barrel-endcap transition region in a calorimeter of the scintillator tile design
We have made a first study of the calorimetric response to 10 GeV/c charged pions in the transition region between barrel and endcap for the scintillator-tile design pursued at Argonne National Laboratory using the simulation program ANLSIM. For (very nearly) projective tower orientations in the barrel, the crack appears deep within a narrow angular range, causing a loss of the response in that region up to 40%. Pointing the towers onto the beam axis 35 cm or more away from the nominal-interaction point leads to a shortened depth of the barrel-endcap crack as seen by particles incident from the interaction region, cutting the maximum loss down by almost one half. The worsening of the resolution follows the same trend. Introduction of a solenoidal coil in front of the calorimeter causes an overall degradation of the response by an amount nearly comparable to the effect of the crack. Electrons of the same incident momentum are more strongly affected by the coil than pions but see only a much narrower region of degradation by the crack. 15 refs., 6 figs., 2 tabs.

Rock equation of state: a constitutive computer model
A constitutive model for a rock equation of state was developed in HEMP and CEL-HEMP computer codes. The model includes the mechanical and thermal properties of soil, such as elasticity, pore closure, compaction, and vaporization. Three test problems were computed using the equation of state: ground motion following the LATIR event, impact vaporization of preheated plates, and surface motion produced from exploding a 3.7-kg(10-lb) charge at a depth of 6.5 m. Agreement between our computations from the model and actual measurements is remarkably close.

Veterans Health Care: Veterans Health Administration Processes for Responding to Reported Adverse Events
Correspondence issued by the Government Accountability Office with an abstract that begins "Through its policy and guidance, VHA has outlined processes that enable VAMCs to respond to reported adverse events that occur. VHA generally grants individual VAMCs discretion on choosing which process to use. Specifically, VAMCs conduct an initial review to determine how best to respond to an adverse event. According to VHA officials, if the circumstances that led to an adverse event are clear, based on a VAMC's initial review, VAMCs can take immediate corrective action. If the circumstances that led to an adverse event need to be examined further, VAMCs are given discretion to use one or more of the following four processes: (1) root cause analysis, (2) peer review, (3) clinical care review, and (4) administrative investigation board. Because VAMCs generally have discretion in which of these processes they use, different VAMCs that experience similar adverse events may not use the same processes to respond to them. Nonetheless, each process has certain purposes and limitations. For example, some of these processes may be used to examine a clinician's actions as they relate to an adverse event, while others may be used to examine whether a systems or …

Group Purchasing Organizations: Services Provided to Customers and Initiatives Regarding Their Business Practices
A letter report issued by the Government Accountability Office with an abstract that begins "Health care providers rely on group purchasing organizations (GPO) to negotiate contracts with vendors of medical products. In 2002, questions were raised about GPOs engaging in potentially anticompetitive business practices such as collecting excessively high contract administrative fees. In 2003, GAO reported that selected GPOs had adopted or revised codes of conduct to respond to the questions about their business practices, but that it was too soon to evaluate the impact of the codes of conduct. GAO was asked to provide information on GPOs. In this report, GAO describes (1) the types of services that GPOs provide and how the GPOs fund these services, (2) initiatives that GPOs have implemented since 2002 to address the questions that had been raised about their business practices, and (3) the reported impact of the GPOs' codes of conduct and other initiatives. To do its work, GAO reviewed GPO documents and collected written responses to structured questions from the six largest GPOs based on their reported 2007 purchasing volume. GAO also conducted follow-up interviews with these six GPOs. GAO interviewed representatives from six GPO customers--hospitals--that varied in size, the GPOs …

Very Light Jets: Several Factors Could Influence Their Effect on the National Airspace System
A letter report issued by the Government Accountability Office with an abstract that begins "For several years, a number of aviation manufacturers have been designing and testing very light jets, a type of small jet aircraft equipped with advanced technologies and priced below other business jets. Aviation forecasters predict that thousands of very light jets will enter the National Airspace System (NAS) over the next two decades, contributing to the overall growth of the general aviation fleet. While some experts predict that very light jets will be used in ways that are similar to current general aviation aircraft, others predict that they will be used to expand the air taxi market to provide on-demand, point-to-point air transportation. In 2006, the Federal Aviation Administration (FAA) certified the first very light jets for flight. This report identifies (1) current very light jet forecasts and what factors could affect very light jet deliveries, (2) how increasing numbers of very light jets might affect the capacity and safety of the NAS, (3) how FAA is planning to accommodate the entry of very light jets into the NAS, and (4) how very light jets might affect FAA's costs and Airport and Airway Trust Fund revenues. …

Border Security: Consular Identification Cards Accepted within United States, but Consistent Federal Guidance Needed
A letter report issued by the Government Accountability Office with an abstract that begins "Several state and local government agencies and financial institutions accept consular identification (CID) cards, which are issued by foreign governments to their citizens living abroad. Mexico issued more than 2.2 million CID cards in 2002-2003 and Guatemala issued approximately 89,000 from mid-2002 to 2003. Critics of CID cards say their acceptance facilitates the unlawful stay within the United States of undocumented aliens and may provide opportunities for terrorists to remain undetected in this country. GAO examined (1) the purpose of a CID card and how Mexican and Guatemalan CID cards are being used in the United States, (2) steps Mexico and Guatemala have taken to verify the identities of CID card applicants and incorporate security features in CID cards now used in the United States, and (3) the positions and policies of federal agencies regarding CID cards."

State and Local Government Pension Plans: Governance Practices and Long-term Investment Strategies Have Evolved Gradually as Plans Take On Increased Investment Risk
A letter report issued by the Government Accountability Office with an abstract that begins "Recent market declines have significantly diminished the asset value of state and local pension plans. Reported unfunded liabilities for these plans are estimated in the hundreds of billions of dollars. As a result, in the long term, these governments may need to make significant fiscal adjustments such as modifying employee benefits, or increasing contributions to plans. They may also alter investment strategies to attempt to maximize returns by assuming increased risk. Consequently, GAO was asked to examine: (1) who makes investment decisions for state and local defined benefit pension plans and what guides their decision making; (2) how plans allocate their assets and manage their investments; and (3) practices that plans are using to meet a range of challenges in governance, investment, or funding. To address these objectives, GAO reviewed relevant literature, interviewed experts in pension and retirement systems, conducted a survey of state and local plans, and performed more detailed reviews of plans in seven states."

Review of FAA's Collegiate Training Initiative as Mandated in the FAA Modernization and Reform Act of 2012
Correspondence issued by the Government Accountability Office with an abstract that begins "The cost effectiveness of the alternative training approach depends on several cost elements that are currently unknown, such as the up-front costs to develop the new controller training curriculum for CTI schools and the duration of the new orientation session at the Academy. However, some direct cost savings to FAA are possible and may be realized under the alternative training approach. These savings include avoiding the cost of pay (salary and per diem) for Academy trainees and not incurring the cost of providing Academy courses for each assigned air traffic control specialization. However, any cost savings could be offset by a number of additional costs that FAA could incur related to the alternative training approach; because some of these costs are unknown at this time, it is unclear whether the alternative approach would be more cost effective. These additional costs would depend primarily on how FAA implements the new training. Also unknown are recurring costs for any additional evaluations FAA would have to undertake to check the accreditation status of CTI schools and to assess graduates' proficiency in the initial specialization coursework. The cost of the mandate's proposed …

Federal Housing Administration: Agency Should Assess the Effects of Proposed Changes to the Manufactured Home Loan Program
A letter report issued by the Government Accountability Office with an abstract that begins "Pending legislation to the Federal Housing Administration's (FHA) Title I Manufactured Home Loan program would increase loan limits, insure each loan, incorporate stricter underwriting requirements, and set up-front premiums. GAO was asked to review (1) selected characteristics of manufactured housing and the demographics of the owners; (2) federal and state consumer protections for owners of manufactured homes; and (3) the potential benefits and costs of the proposed changes for borrowers and the federal government. In addressing these objectives, GAO analyzed select Census data; researched federal laws and laws in eight states; interviewed local, state, and federal officials; and analyzed various scenarios that might affect Title I program costs."

Home Energy Assistance for Low-Income Occupants of Manufactured Homes
Correspondence issued by the Government Accountability Office with an abstract that begins "In 2005, the most recent year for which complete data were available, occupants of older manufactured homes paid over twice as much on average per square foot for energy---$1.75 per square foot as compared with $0.87---as was paid by occupants of detached homes. Annual energy expenditures for older manufactured homes--about 906 square feet on average--were about $1,369, compared with detached homes--about 2,919 square feet on average--were about $2,060. Energy expenditures--both per square foot and annually--varied significantly by region reflecting regional differences in the types and costs of fuels commonly used to heat and cool homes, income levels, and climate, among other things. In 2005, LIHEAP provided more assistance on a per square foot basis--about $0.33 per square foot--to occupants of older manufactured homes than to those of detached homes--about $0.20 per square foot. However, this assistance covers slightly less of the annual energy expenditures of occupants of older manufactured homes than occupants of detached homes--15 and 17 percent, respectively. Based on our analysis of EIA's RECS data, we estimate that about 3 percent of LIHEAP funds--about $57 million--spent in 2005 were used to assist occupants of older manufactured …

Strategic Petroleum Reserve: Available Oil Can Provide Significant Benefits, but Many Factors Should Influence Future Decisions about Fill, Use, and Expansion
A letter report issued by the Government Accountability Office with an abstract that begins "Congress authorized the Strategic Petroleum Reserve (SPR), operated by the Department of Energy (DOE), to release oil to the market during supply disruptions and protect the U.S. economy from damage. The reserve can store up to 727 million barrels of crude oil, and currently contains enough oil to offset 59 days of U.S. oil imports. GAO answered the following questions: (1) What factors do experts recommend be considered when filling and using the SPR? (2) To what extent can the SPR protect the U.S. economy from damage during oil supply disruptions? (3) Under what circumstances would an SPR larger than its current size be warranted? As part of this study, GAO developed oil supply disruption scenarios, used models to estimate potential economic harm, and convened 13 experts in conjunction with the National Academy of Sciences."

Nonprime Mortgages: Analysis of Loan Performance, Factors Associated with Defaults, and Data Sources
A letter report issued by the Government Accountability Office with an abstract that begins "The surge in mortgage foreclosures that began in late 2006 and continues today was initially driven by deterioration in the performance of nonprime (subprime and Alt-A) loans. Nonprime mortgage originations increased dramatically from 2000 through 2006, rising from about 12 percent ($125 billion) of all mortgage originations to about 34 percent ($1 trillion). The nonprime market contracted sharply in mid-2007, partly in response to increasing defaults and foreclosures for these loans. This report (1) provides information on the performance of nonprime loans through December 31, 2009; (2) examines how loan and borrower characteristics and economic conditions influenced the likelihood of default (including foreclosure) of nonprime loans; and (3) describes the features and limitations of primary sources of data on nonprime loan performance and borrower characteristics, and discusses federal government efforts to improve the availability or use of such data. To do this work, GAO analyzed a proprietary database of securitized nonprime loans and Home Mortgage Disclosure Act data, and reviewed information on mortgage data sources maintained by private firms and the federal government."

Defense Management: Better Guidance Needed in Selecting Operating Methods for Name-Brand, Fast-Food Restaurants
A letter report issued by the General Accounting Office with an abstract that begins "The military exchange services operate a wide range of retail activities, such as department stores, florist shops, barber and beauty shops, gas stations, and restaurants. Hamburger restaurants represent a major segment of the exchange services' name-brand, fast-food sales. The exchange services use either a direct or an indirect method to operate these restaurants. Under the direct method, the exchange service enters into a franchise agreement with a name-brand company to sell its product on a military installation. As the franchisee, the exchange service builds and operates the restaurant and directly employs and trains the personnel. In turn, the exchange service receives all of the revenues and profits and usually pays the company a licensing fee plus a percentage of the restaurant's sales. Under the indirect method, the exchange service contracts with a name-brand company that, in turn, builds the restaurant and either operates it as a company restaurant or provides a licensed operator. The company or its licensed operator hires, trains, and pays the restaurant personnel and usually pays annual fees and commissions to the exchange service on the basis of restaurant's sales. Under this agreement, …

Summary of Reinsurance Activities and Rating Actions Tied to Selected Insurers Involved in the Failed 'Unicover' Venture
Correspondence issued by the General Accounting Office with an abstract that begins "Workers' compensation "occupational accident" policies were brought to the reinsurance market by Unicover Managers, Inc., a reinsurance pool manager and intermediary. Reinsurance is the acceptance by one insurance company of a portion of the risk or claims loss underwritten by another insurance company for a share of the premium to support that risk. In a reinsurance pool arrangement, several reinsurers combine their capital and delegate underwriting authority to a pool manager that is normally not exposed to risk from the reinsurance. Losses from the failed Unicover venture came in the wake of rapid, high-volume, multilevel reinsurance of portions of workers' compensation policies that were initially underpriced in the aggregate because of a highly competitive market. Reinsurance activities had the effect of subsidizing unprofitable workers' compensation insurance at the expense of insurance companies that reinsured the business. Five rating agencies took a series of rating downgrade actions on two of the five insurance companies GAO reviewed. The other three insurance companies experienced substantial losses but were not downgraded because either the insurer was more than adequately capitalized or the parent organization made capital contributions to cover the anticipated losses …

Amtrak: Improved Management and Controls over Food and Beverage Service Needed
A letter report issued by the Government Accountability Office with an abstract that begins "Food and beverages have been served on board National Railroad Passenger Corporation (Amtrak) trains since Amtrak was created. Amtrak's 11 commissaries, located around the country, are responsible for receiving, warehousing and stocking food, beverages, and other items for Amtrak's on-board dining and cafe service. January 1999, Amtrak ran these commissaries with its own employees. Since then, Amtrak has contracted out the responsibility for the commissaries and for ordering and stocking all food, beverage, and related items under a contract that expires in September 2006. Gate Gourmet, the contractor, is also a supplier of food and beverages to several major airlines. During fiscal years 2002 through 2004, the period we focused on in our audit work, Amtrak paid Gate Gourmet between $59 million and $64 million a year in reimbursements and fees. Gate Gourmet personnel operate Amtrak-owned commissaries and order, receive, store, and stock trains with food, beverages, and other related items, such as table linens and napkins. Food and beverage supplies are charged to Amtrak employees who provide on-board food and beverage service and account for the food and beverages en route. When a train arrives …
