Experimental studies of the Li/sup +/ + He interaction have been extended to smaller internuclear separations to clarify a discrepancy between experiment and theory in the elastic cross sections and to observe and measure cross sections for inelastic excitation. For R less than or equal to 0.5 a/sub 0/ the elastic scattering differential cross section is observed to droop far below that expected from a single-state interaction based on ab initio ground-state potentials. In this same region of R both one- and two-electron excitations of He are observed to be strongly excited, and cross sections were measured for each of them. The lowest inelastic channel is an electron-capture state, which is observed indirectly to be strongly populated also. A diabatic correlation diagram is constructed that exhibits the basic interactions responsible for the excitation.

The extraction of information from measured or computed data is all-pervasive; to gain the most value from extracted information, it must often be transformed from one type of data into another, a process that can only preserve or lose information. An information-transformation process based upon Prony's method was found to be increasingly useful for application to electromagnetic-type problems in particular and a growing variety of physical problems in general. This procedure allows the coefficients and exponents (or parameters) of an exponential series to be derived from a sequence of its sampled values. Two basic issues are associated with Prony processing: determination of the status of the input data and application of the procedure as effectively as possible to maximize the information content of the output. The possible uses of the Prony method as an information on-transformation process are discussed; the insight gained from this viewpoint concerning the information content of data is emphasized. Waveform and spectrum characterization, data compression, and inversion of pattern data are considered briefly as applications. 8 figures, 3 tables. (RWR)

A letter report issued by the Government Accountability Office with an abstract that begins "The total number of aliens detained per year by the Department of Homeland Security's (DHS) U.S. Immigration and Customs Enforcement (ICE) increased from about 95,000 in fiscal year 2001 to 283,000 in 2006. The care and treatment of these detained aliens is a significant challenge to ICE. GAO was asked to review ICE's implementation of its detention standards for aliens in its custody. GAO reviewed (1) detention facilities' compliance with ICE's detention standards, (2) ICE's compliance review process, and (3) how detainee complaints regarding conditions of confinement are handled. To conduct its work, GAO reviewed DHS documents, interviewed program officials, and visited 23 detention facilities of varying size, type, and geographic location."

A letter report issued by the Government Accountability Office with an abstract that begins "The safety of the nation's flying public depends, in large part, on the aviation industry's compliance with safety regulations and the Federal Aviation Administration's (FAA) enforcement of those regulations when violations occur. FAA attempts to gain the industry's compliance through enforcement tools, including levying fines and suspending or revoking operating certificates, and partnership programs that allow participating companies or individuals to self-report violations of safety regulations and mitigate or avoid fines or other legal actions. GAO was asked to assess how FAA uses its enforcement options to address noncompliance and what management controls are in place to ensure that enforcement efforts and partnership programs result in compliance with aviation safety regulations."

A letter report issued by the Government Accountability Office with an abstract that begins "The U.S. Merchant Marine Academy (Academy) has made progress in improving its internal control since GAO’s August 2009 report, but has not yet fully addressed one key recommendation related to fundamental weaknesses in its overall internal control system. GAO found that while the Academy had appointed an Internal Control Officer responsible for coordinating reviews of internal controls, it had not yet established a comprehensive risk-based internal control system to ensure effective and efficient operations, reliable financial reporting, and compliance with laws and regulations, including a monitoring system to help ensure that control deficiencies are proactively identified and promptly corrected. Maritime Administration (MARAD) officials stated that their strategy had been to focus on the deficiencies that could be readily resolved. As of September 30, 2011, Academy and MARAD officials had addressed 32 of the other 46 prior recommendations regarding control activity deficiencies."

A letter report issued by the Government Accountability Office with an abstract that begins "The Pension Benefit Guaranty Corporation (PBGC) insures the pensions of millions of private sector workers and retirees in certain employer-sponsored pension plans. It is governed by a board of directors consisting of the Secretaries of the Treasury, Labor, and Commerce, who are charged with providing PBGC with policy direction and oversight. This report assesses (1) the extent to which PBGC's governance structure provides PBGC with policy direction and oversight, and (2) whether administrative responsibilities among the PBGC board, Department of Labor (DOL), and PBGC management are clearly defined. We examined corporate governance practices, select federal government corporations, and reviewed documents on PBGC's structure. We interviewed officials from all board member agencies and PBGC, among others."

A letter report issued by the Government Accountability Office with an abstract that begins "Livestock production contributed nearly $123 billion to the U.S. economy in 2006. In response to concerns about animal disease outbreaks, the U.S. Department of Agriculture (USDA) announced in December 2003 that it would implement a nationwide program--later named the National Animal Identification System (NAIS)--to help producers and animal health officials respond quickly and effectively to animal disease events in the United States. In this context, GAO determined (1) how effectively USDA is implementing NAIS and, specifically, the key issues identified by livestock industry groups, market operators, state officials, and others; (2) how USDA has distributed cooperative agreement funds to help states and industry prepare for NAIS and evaluated the agreements' results; and (3) what USDA and others estimate are the costs for USDA, states, and industry to implement NAIS. In conducting its work, GAO reviewed USDA documents; interviewed agency, industry, and state officials; and consulted 32 animal identification (ID) experts."

A letter report issued by the Government Accountability Office with an abstract that begins "Congress established federal standards for the child support enforcement program (CSE) in 1975. State agencies administer the program and the Office of Child Support Enforcement (OCSE) in the Department of Health and Human Services (HHS) oversees it. The CSE program provides several services, including collecting child support payments from noncustodial parents--those who are not the primary caregivers--and distributing these payments to families. Generally, the federal government reimburses state agencies 66 percent of their costs for administering the CSE program. GAO determined (1) how total net federal expenditures for administrative costs changed from fiscal year 2000 to fiscal year 2004; (2) the categories of costs that contributed most to administrative costs in recent years; and (3) steps state agencies have taken to manage costs, and steps OCSE has taken to help state agencies and ensure federal funds have been used appropriately. GAO analyzed program data, surveyed all 54 state agencies and visited 6, interviewed program officials, and reviewed laws, policies, and reports."

A letter report issued by the Government Accountability Office with an abstract that begins "The Cheyenne Mountain Operations Center houses numerous complex computer systems for tracking air, missile, and space events that could threaten homeland security or undermine military operations in theater. To ensure this mission can be met, the systems require ongoing upgrades. The most recent upgrade program--the Combatant Commanders' Integrated Command and Control System (CCIC2S)--was initiated in 2000. Given the critical missions supported by Cheyenne Mountain systems, GAO initiated a review to (1) determine the status of the CCIC2S program in terms of meeting its cost, schedule, and performance goals; (2) gauge the extent to which DOD has followed best practices in managing program requirements; and (3) assess DOD's control and oversight mechanisms for CCIC2S."

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO provided information on the ability of homeless people to obtain assistance through mainstram federal programs, focusing on: (1) why homeless people cannot always access or effectively use federal mainstream programs; and (2) how the federal government can improve homeless people's access to, and use of, these programs."

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO provided information on the Environmental Protection Agency's (EPA) information security program, focusing on: (1) EPA's computer-based controls; (2) the extent and impact of computer security incidents at EPA; and (3) the agency's information security program management."

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO reviewed federal oversight of depository institutions' Internet banking activities, focusing on: (1) the risks posed by Internet banking and the extent of any industrywide Internet banking-related problems; (2) the methods used by regulators to track depository institutions' plans to provide Internet banking services; (3) how regulators examined Internet banking activities; and (4) the extent to which regulators examined firms providing Internet banking support services to depository institutions."

A letter report issued by the General Accounting Office with an abstract that begins "This report reviews the Food and Drug Administration's (FDA) inclusion of women in clinical drug trials. GAO found that women were a majority of the clinical trial participants in the new drug applications (NDA) it examined and that every NDA included enough women in the pivotal studies to be able to statistically demonstrate that the drug is effective in women. Although these findings are welcome, GAO also found three areas of concern. The first is the relatively small proportion of women in early small-scale safety studies. These early studies provide important information on drugs' toxicity and safe dosing levels for later stages of clinical development, and many of the NDAs GAO examined found significant sex differences in a drug's pharmacokinetics, or how it is absorbed, distributed, metabolized, excreted, and concentrated in the bloodstream. Second, GAO is not confident that either NDA sponsors or FDA's reviewers took full advantage of the available data to learn more about the effects of the drug in women and to explore potential sex differences in dosing. This is because NDA summary documents are not required to include analyses of sex differences, …

A letter report issued by the General Accounting Office with an abstract that begins "Since the end of the Persian Gulf War in February 1991, the Department of Defense (DOD) has reported over $25 billion in incremental costs for its overseas contingency operations. These operations include the enforcement of no-fly zones, humanitarian assistance, and peace enforcement operations. The majority of these costs ($22 billion) have been incurred in the Balkans (Bosnia and Kosovo) and Southwest Asia. In fiscal year 2001, U.S. military forces are continuing to participate in a number of contingency operations, primarily in the Balkans and Southwest Asia. In this report, GAO reviews (1) the adequacy of DOD's incremental contingency operations funding for all ongoing contingency operations in fiscal year 2001, (2) DOD's estimated contingency operations costs for fiscal year 2002, and (3) the ramifications of DOD's plan to change the method for funding its operations in Southwest Asia. GAO found that (1) existing funds are sufficient to cover DOD's estimated costs for ongoing contingency operations for fiscal year 2001, (2) in June 2001, the administration submitted a revised fiscal year 2002 budget for DOD, which included $4 billion for ongoing operations in the Balkans and Southwest Asia, …

A letter report issued by the Government Accountability Office with an abstract that begins "Policymakers and researchers have focused on improving the quality of our nation's 3 million teachers to raise the achievement of students in key academic areas, such as reading and mathematics. Given the importance of teacher quality to student achievement and the key role federal and state governments play in supporting teacher quality, GAO's objectives included examining (1) the extent that the U.S. Department of Education (Education) funds and coordinates teacher quality programs, (2) studies that Education conducts on teacher quality and how it provides and coordinates research-related assistance to states and school districts, and (3) challenges to collaboration within states and how Education helps address those challenges. GAO interviewed experts and Education officials, administered surveys to officials at state educational agencies and state agencies for higher education in the fall of 2008, and conducted site visits to three states."

On June 22, 2009, two transit trains in Washington, DC, collided, resulting in nine deaths and dozens of injuries. It was the worst crash in the history of the Washington Metropolitan Area Transit Authority's rail transit system. This crash has raised questions about the safety of rail transit and the government's role in ensuring that safety. Nationwide, rail transit is considered one of the safest modes of transportation. This report discusses the State Safety Oversight Program, which went into effect in 1997 and mandates that states are responsible for the safety of the rail transit systems within their borders. This report also explores several issues that Federal Transit Administration (FTA) representatives have discussed in regards to improving the Safety Oversight Program.

Published reports have suggested that in the wake of the 9/11 terrorist attacks, the Pentagon has expanded its counter-terrorism intelligence activities as part of what the Bush Administration termed the global war on terror. This report discusses the Department of Defense's (DOD) various counter-terrorist intelligence activities, whether or not they constitute classification as "covert action," and the challenge of clarifying the roles and responsibilities of various intelligence activities with regard to clandestine activities. This report examines the statutory procedures governing covert action and associated questions to consider.

This report discusses the efforts currently underway to improve coordination and encourage better analysis amongst the various agencies within the U.S. Intelligence Community, especially with regard to the ongoing and prominent issue of international terrorism. In particular, this report addresses the false intelligence regarding Iraqi weapons of mass destruction and the current efforts in Iraq and Iran in general.

Many potential chemical, biological, radiological, and nuclear (CBRN) terrorism agents lack available countermeasures. In 2003, President Bush proposed Project BioShield to address this need. The Project BioShield Act became law in July 2004. This report discusses the three main provisions of Project BioShield, funding for Project BioShield, and additional measures that Congress has considered since Project BioShield's implementation to further encourage CBRN countermeasure development.

Recent policies have sought to contain damages spilling over from housing and financial markets to the broader economy, including monetary policy, which is the responsibility of the Federal Reserve, and fiscal policy, including a tax cut in February 2008 of $150 billion and two extensions of unemployment compensation in June and November of 2008. This report discusses this problem as well as certain interventional measures that the government has taken and is considering taking to combat it, including various fiscal stimulus packages.

In October 2007, the United States and Mexico announced the Mérida Initiative, a three-year program of U.S. assistance to Mexico and Central America to combat drug trafficking, gangs, and organized crime. This report provides an overview and discussion of the funding provided for Mérida, and presents several issues that Congress may consider as it oversees implementation of the Initiative and shapes its future direction.

The Google Book Search Library Project, announced in December 2004, raised important questions about infringing reproduction and fair use under copyright law. Google planned to digitize, index, and display "snippets" of print books in the collections of five major libraries without the permission of the books' copyright holders, if any. Google's proposed reproduction and display of copyrighted books was not authorized by the rights holders, who alleged that the Google Library Project infringed their copyrights. This report provides background on the Library Project, legal issues raised by digitization and indexing projects, and the proposed settlement.
