Studies of Nuclear Resonant Absorption of Gamma Rays. Quarterly Report No. 4 Covering Period June 1, 1961 to August 31, 1961
The effect of polarizing mngnetic field intensity on the nuclear resonant absorption was studied by varying the field strength at a 1-mc Co/sup 57/ source from 0 to 1000 gauss while keeping the absorber between the poles of a magnet having a fixed field of 800 gauss. The rates of resonance absorption change with field intensity were greatest in the region of 300 to 1000 gauss, and the% nuclear resonant absorption for 1000-gauss fields was 8.5 and 26% for perpendicular and parallel fields, respectively, as compared with 15% for no fields. Other absorption measurements for Co/sup 57/ sources are also reported. Calculations on the use of nuclear resonant absorption to measure gravitational fields and altitudes were made which indicates that this application is not promising. (D.L.C.)

Photomultiplier characteristics considerations for the deep underwater muon and neutrino detection system
The results of an investigation of the characteristics of photomultipliers for the Deep Underwater Muon and Neutrino Detection (DUMAND) System are discussed. The pulse-height resolution, the afterpulsing phenomena and the gain sensitivity to the ambient magnetic field have been determined for large photocathode area photomultipliers. Furthermore, the transient time difference, the single photoelectron time spread, and the collection and photocathode quantum efficiency uniformity as a function of the position of the photocathode sensing area have been reviewed. Finally, an attempt has been made to estimate the photomultiplier reliability and its lifetime.

Enhanced durability and reactivity for zinc ferrite desulfurization sorbent
AMAX Research Development Center (AMAX R D) has been investigating methods for enhancing the reactivity and durability of the zinc ferrite desulfurization sorbent. Zinc ferrite sorbents are intended for use in desulfurization of hot coal gas in integrated gasification combined cycle (IGCC) or molten carbonate fuel cell (MCFC) applications. For the present program, the reactivity of the sorbent may be defined as its sulfur sorption capacity at the breakthrough point and at saturation in a bench-scale, fixed-bed reactor. Durability may be defined as the ability of the sorbent to maintain important physical characteristics such As size, strength, and specific surface area during 10 cycles of sulfidation and oxidation.

Military Personnel: Financial Cost and Loss of Critical Skills Due to DOD's Homosexual Conduct Policy Cannot Be Completely Estimated
A letter report issued by the Government Accountability Office with an abstract that begins "From the passage of the homosexual conduct policy statute, in fiscal year 1994, through fiscal year 2003 the military services separated about 9,500 servicemembers for homosexual conduct. This represents about 0.40 percent of the 2.37 million members separated for all reasons during this period. Questions have been raised about the costs of separating servicemembers for homosexual conduct. Also, in the post-September 11th environment, there has been concern about the separation of servicemembers with critical occupations or important foreign language skills in, for example, Arabic. GAO was asked to determine (1) the military services' annual financial costs from fiscal year 1994 through fiscal year 2003 for certain activities associated with administering the Department of Defense's (DOD) policy on homosexual conduct--e.g., the recruitment and training of servicemembers to replace those separated under the homosexual conduct statute--and (2) the extent to which the policy has resulted in the separation of servicemembers with critical occupations and important foreign language skills. GAO provided DOD with a draft of this report for comment, and DOD provided additional information on separations for homosexual conduct compared with other unprogrammed separations."

The Nation's Long-Term Fiscal Outlook: January 2007 Update
Correspondence issued by the Government Accountability Office with an abstract that begins "Since 1992, GAO has published long-term fiscal simulations of what might happen to federal deficits and debt levels under varying policy assumptions. GAO developed its long-term model in response to a bipartisan request from Members of Congress who were concerned about the long-term effects of fiscal policy. In 1992 GAO said: "The federal budget is structurally unbalanced. This will do increasing damage to the economy and is unsustainable in the long term. Regardless of the approach chosen, prompt and meaningful action is essential. The longer it is delayed, the more painful it will be." These words are as relevant today as when GAO first published them. GAO updates its simulations three times a year as new estimates become available from the Congressional Budget Office's (CBO) Budget and Economic Outlook (January), Social Security and Medicare Trustees Reports (early spring), and CBO's Budget and Economic Outlook: An Update (late summer)."

Homeland Security: Federal Action Needed to Address Security Challenges at Chemical Facilities
Testimony issued by the General Accounting Office with an abstract that begins "The events of September 11, 2001, triggered a national re-examination of the security of thousands of industrial facilities that use or store hazardous chemicals in quantities that could potentially put large numbers of Americans at risk of serious injury or death in the event of a terrorist-caused chemical release. GAO was asked to examine (1) available information on the threats and risks from terrorism faced by U.S. chemical facilities; (2) federal requirements for security preparedness and safety at facilities; (3) actions taken by federal agencies to assess the vulnerability of the industry; and (4) voluntary actions the chemical industry has taken to address security preparedness, and the challenges it faces in protecting its assets and operations. GAO issued a report on this work in March 2003 (GAO-03-439)."

2010 Census: Key Enumeration Activities Are Moving Forward, but Information Technology Systems Remain a Concern
Testimony issued by the Government Accountability Office with an abstract that begins "In March 2008, GAO designated the 2010 Census a high-risk area in part because of information technology (IT) shortcomings and uncertainty over the ultimate cost of the census, now estimated at around $15 billion. The U.S. Census Bureau (Bureau) has since made improvements to various IT systems and taken other steps to mitigate the risks of a successful census. However, last year, GAO noted that a number of challenges and uncertainties remained, and much work remained to be completed under very tight time frames. As requested, this testimony provides an update on the Bureau's readiness for an effective headcount, covering (1) the status of key IT systems; (2) steps the Bureau has taken to revise its cost estimates; and (3) the extent to which critical enumeration activities, particularly those aimed at hard-to-count populations, are on track. The testimony is based on previously issued and ongoing GAO work."

Telecommunications: GSA Has Accumulated Adequate Funding for Transition to New Contracts but Needs Cost Estimation Policy
A letter report issued by the Government Accountability Office with an abstract that begins "The General Services Administration (GSA) and its customer agencies are preparing to transition new governmentwide telecommunications contracts known as the Networx program. GSA estimated the costs for which it is responsible to be $151.5 million. This report addresses (1) the soundness of the analysis GSA used to derive the estimate of funding that would be required for the transition and (2) whether GSA will have accumulated adequate funding to pay for transition costs. In performing this work, GAO reviewed cost estimation best practices, analyzed relevant GSA documents, and performed an uncertainty analysis on GSA's estimate."

Fisheries Management: Core Principles and a Strategic Approach Would Enhance Stakeholder Participation in Developing Quota-Based Programs
A letter report issued by the Government Accountability Office with an abstract that begins "Dedicated access privilege (DAP) programs are one tool the National Marine Fisheries Service (NMFS) uses to help end overfishing and promote conservation. Under a DAP program, NMFS sets an allowable catch in a fishery and allocates the privilege to harvest a portion of the total to eligible entities, such as fishermen. Because DAP programs can have significant impacts on fishermen and their communities, many believe that effective participation by fishermen and other stakeholders in the development of these programs is critical. GAO was asked to determine (1) the extent to which the regional fishery management councils are using a framework for effective participation and (2) the methods stakeholders and participation experts suggest for enhancing stakeholder participation in developing DAP programs."

Postsecondary Education: College and University Endowments Have Shown Long-Term Growth, While Size, Restrictions, and Distributions Vary
A letter report issued by the Government Accountability Office with an abstract that begins "The nation's 4-year not-for-profit colleges and universities collectively held more than $400 billion in endowments in 2008. Some institutions' large endowments coupled with the high and growing cost of college have led to questions about institutions' use of endowments. This mandated report describes (1) the size and change in value of endowments over the last 20 years, (2) the extent and manner to which endowment funds are restricted for financial aid and other purposes, and (3) institutions' distribution of endowment assets. GAO obtained and analyzed data on college and university endowments from the Department of Education and other sources. Because industry-wide data were not available on endowment restrictions and distributions, GAO selected 10 colleges and universities for case studies. The case-study institutions were selected to include a mix of public, private, large, small, and minority-serving institutions. Information from these schools cannot be generalized to all U.S. colleges and universities."

Federal Capital: Three Entities' Implementation of Capital Planning Principles Is Mixed
A letter report issued by the Government Accountability Office with an abstract that begins "In fiscal year 2005, the federal government spent nearly $117 billion on capital investments intended to yield long-term benefits for its operations. Effective capital planning ensures that the sizable investments made by federal agencies result in the most efficient return to taxpayers. Accordingly, GAO evaluated (1) how well selected entities followed the planning phase principles of GAO's Executive Guide and the Office of Management and Budget's (OMB) Capital Programming Guide, (2) OMB's actions to encourage all agencies to conform with capital planning principles, and (3) what capital planning information is received by or would be useful to congressional decision makers. Based on missions, asset types, and capital spending, we selected three entities to review within the Departments of Energy (DOE) and Homeland Security (DHS)."

Highway Emergency Relief: Reexamination Needed to Address Fiscal Imbalance and Long-term Sustainability
A letter report issued by the Government Accountability Office with an abstract that begins "Since 1972, Congress has authorized $100 million a year for highway disaster recovery needs through the Federal Highway Administration's (FHWA) Emergency Relief (ER) program. Increasingly, the program's actual costs have exceeded this amount, and Congress has provided additional funding. Because of this fiscal imbalance between program funding and program needs, we reviewed ER under the Comptroller General's authority to determine the (1) total funding, distribution of funds among the states, and disaster events funded; (2) sources of funding provided and financial challenges facing the program; and (3) scope of activities eligible for funding and how the scope of eligible activities has changed in recent years. GAO's study is based on financial data, document analysis, stakeholder interviews, and site visits, among other methods."

DHS: Organizational Structure and Resources for Providing Health Care to Immigration Detainees
Correspondence issued by the Government Accountability Office with an abstract that begins "Recent events have drawn attention to the health care provided to detainees held by U.S. Immigration and Customs Enforcement (ICE), a component of the Department of Homeland Security (DHS). For fiscal year 2004 through fiscal year 2007, ICE reported that 69 detainees died while in ICE custody, and during 2008, national news organizations investigated and published reports of the circumstances surrounding several detainee deaths. Other reports have also outlined concerns about the health care provided to detainees. For example, in 2007, the DHS Office of the Inspector General (OIG) found problems with adherence to ICE's medical standards at two ICE facilities it reviewed where detainee deaths had occurred. Additionally, members of Congress, the media, and advocacy groups have raised questions about the health care provided to detainees in ICE custody. An explanatory statement accompanying the fiscal year 2009 DHS appropriations act directed ICE to fund an independent, comprehensive review of the medical care provided to persons detained by DHS and identified $2 million for that purpose. ICE was created in March 2003 as part of DHS. From fiscal year 2003 through fiscal year 2007, the average daily population …

Temporary Assistance for Needy Families: Fewer Eligible Families Have Received Cash Assistance Since the 1990s, and the Recession's Impact on Caseloads Varies by State
A letter report issued by the Government Accountability Office with an abstract that begins "Following sweeping changes made to federal welfare policy in 1996 with the creation of the Temporary Assistance for Needy Families (TANF) program, the number of needy families who received cash assistance fell by more than half to 1.7 million in 2008. Poverty among children also fell from about 21 percent in 1995 to about 16 percent in 2000, rising again to 19 percent in 2008. The current recession deepened in 2008, raising questions about state TANF programs' response to increased needs. GAO was asked to provide Congress with information on the (1) factors contributing to the decline in the number of families receiving assistance; (2) characteristics of participating and nonparticipating eligible families; (3) impact of higher participation in TANF cash assistance on child poverty; and (4) changes states are experiencing in caseloads and spending in the current recession. GAO's methodologies included using microsimulation analyses; reviewing relevant research and federal laws; interviewing TANF officials in 21 selected states; analyzing state cash assistance data; and interviewing researchers, federal officials, and other experts."

Higher Education: Information on Incentive Compensation Violations Substantiated by the U.S. Department of Education
Correspondence issued by the Government Accountability Office with an abstract that begins "In 1992, Congress banned schools participating in federal student aid programs from paying commissions, bonuses, or other incentive payments to individuals based on their success in enrolling students or securing financial aid for them. Congress instituted this incentive compensation ban to eliminate abusive recruiting practices in which schools enrolled unqualified students who then received federal student aid funds. In 2002, the U.S. Department of Education (Education) issued regulations--commonly referred to as "safe harbors"--that allowed for 12 activities or payment arrangements that schools could use without violating the ban against incentive compensation. As of January 2010, Education was reviewing these safe harbor regulations as part of a negotiated rule making process to maintain or improve federal student aid programs. The Higher Education Opportunity Act (HEOA) mandated that GAO conduct a study on Education's enforcement of the incentive compensation ban in light of the safe harbors and report on the number of violations substantiated by the Secretary of Education since 1998, the nature of these violations, and the names of the institutions involved. As agreed with Congressional offices, this report provides information on violations of the incentive compensation ban substantiated …

Motor Fuels: Gasoline Prices in Oregon
Correspondence issued by the General Accounting Office with an abstract that begins "This correspondence provides information on (1) factors affecting retail gasoline prices in Oregon, including transportation costs, taxes, costs of full service, and other supply and demand conditions and (2) how gasoline price trends in Portland, Oregon, compare with trends in other West Coast cities. GAO identified several factors affecting gasoline prices in Oregon, including (1) higher-than-average costs associated with transporting gasoline from refiners to consumers because Oregon has no refining capability and a greater proportion of its gasoline demand comes from rural driving, (2) higher-than-average state gasoline taxes, and (3) a prohibition on self-service gasoline stations. GAO also found that although Portland's gas prices differ from those of Los Angeles, San Francisco, and Seattle, all four cities responded similarly to rapid price changes. Retail prices in all four cities follow similar patterns with respect to major periods of price increases and decreases."
