Limits on likesign dilepton production in nu/sub. mu. / interactions
We have searched for the production of likesign dilepton events (nu/sub ..mu../ + Ne ..-->.. ..mu../sup -/ + e/sup -/ + ...) in a wideband neutrino beam at FNAL using the 15' bubble chamber. We observe no signal above the background arising from conventional sources. We set 90% confidence level upper limits for the production rates of (nu/sub ..mu../ + Ne ..-->.. ..mu../sup -/ + e/sup -/ + ...)/(nu/sub ..mu../ + Ne ..-->.. ..mu../sup -/ + ...) less than or equal to 8 * 10/sup -5/ and (nu/sub ..mu../ + Ne ..-->.. ..mu../sup -/ + e/sup -/ + ...)/(nu/sub ..mu../ + Ne ..-->.. ..mu../sup -/ + e/sup +/ + ...) less than or equal to 6 * 10/sup -2/.

New developments in measurement technology relevant to the studies of deep geological repositories in domed salt and basalt
This report briefly describes recent geophysical and geotechnical instrumentation developments relevant to the studies of deep geologic repositories. Special emphasis has been placed on techniques that appear to minimize measurement problems associated with repositories constructed in basalt or domed salt. Included in the listing are existing measurement capabilities and deficiencies that have been identified by a few authors and instrumentation workshops that have assessed the capabilities of existing instrumentation with respect to repository applications. These deficiencies have been compared with the reported advantages and limitations of the new developments described. Based on these comparisons, areas that merit further research and development have been identified. The report is based on a thorough literature review and on discussions with several instrumentation specialists involved in instrumentation development.

The impact of changing land use, nitrate deposition and CO sub 2 fertilization on soil carbon storage
This research strives to assess the impact of changing land use, nitrate deposition and CO{sub 2} fertilization on soil carbon storage. Our motivation is that this reservoir is the most likely candidate for the so-called missing carbon sink. We are working on several aspects of this problem by measuring carbon content, nitrogen content and radiocarbon ratios in paired soil samples from neighboring sites, to determine the impact of land use on soil carbon inventories and turnover times. We are also gathering information on how the C/N ratios in soils vary with climate and changing land use, in an effort to estimate how much carbon has been sequestered as a result of atmospheric fallout of NH{sub 4}OH and HNO{sub 3}. Finally, we are developing a soil greening model that uses CO{sub 2} growth-enhancement results and bomb radiocarbon-based estimates of soil carbon inventory response times.

Overstay Tracking: A Key Component of Homeland Security and a Layered Defense
A letter report issued by the General Accounting Office with an abstract that begins "Each year, millions of visitors, foreign students, and immigrants come to the United States. Foreign visitors may enter on a legal temporary basis--that is, with an authorized period of admission that expires on a specific date--either (1) with temporary visas (generally for tourism, business, or work) or, in some cases, (2) as tourists or business visitors who are allowed to enter without visas. (The latter include Canadians and qualified visitors from 27 countries who enter under the visa waiver program.) The majority of visitors who are tracked depart on time, but others overstay--and since September 11, 2001, the question has arisen as to whether overstay issues might have an impact on domestic security. In this report, we (1) describe available data on the extent of overstaying, (2) report on weaknesses in the Department of Homeland Security's long-standing overstay tracking system, and (3) provide some observations on the impact that tracking system weaknesses and significant levels of overstaying may have on domestic security."

Defense Inventory: Air Force Item Manager Views of Repair Parts Issues Consistent With Issues Reported in the Past
Correspondence issued by the General Accounting Office with an abstract that begins "Since 1990 we have consistently identified the Department of Defense's (DOD) management of secondary inventory (spare and repair parts, medical supplies, and other items to support the operating forces) as a high-risk area because inventory levels were too high and management systems and procedures were ineffective. In addition, DOD has attributed readiness problems to parts shortages. Previously, we reported on the wide variety of reasons for inventory of spare parts being above or below the levels needed to satisfy current inventory requirements. This is one in a series of reports addressing defense inventory vulnerabilities to fraud, waste, and abuse. Congress asked that we specifically obtain the views about defense inventory imbalances from item managers, i.e., those who are responsible for maintaining the right amount of inventory."

Consumer Product Safety Commission: A More Active Role in Voluntary Standards Development Should Be Considered
A letter report issued by the Government Accountability Office with an abstract that begins "Although the Consumer Product Safety Commission (CPSC) enforces compliance with mandatory federal safety standards, it is also required by law to rely on voluntary safety standards when it determines that the standard adequately addresses the product hazard and is likely to have substantial compliance. Voluntary standardsdeveloped by industry, consumer, and government participants through a consensus processcover many of the thousands of types of products in CPSCs jurisdiction. Compliance with voluntary standards is not routinely tracked, but it is generally considered to be high by industry participants. Compliance with these standards also depends on industry and legal factors, such as retailer requirements to demonstrate proof of compliance with voluntary safety standards and risk of liability in product liability lawsuits."

U.S. Fish and Wildlife Service: Endangered Species Act Decision Making
Testimony issued by the Government Accountability Office with an abstract that begins "The Department of the Interior's (Interior) U.S. Fish and Wildlife Service (Service) is generally required to use the best available scientific information when making key decisions under the Endangered Species Act (ESA). Controversy has surrounded whether former Deputy Assistant Secretary Julie MacDonald may have inappropriately influenced ESA decisions by basing decisions on political factors rather than scientific data. Interior directed the Service to review ESA decisions to determine which decisions may have been unduly influenced. ESA actions include, among others, 90-day petition findings, 12-month listing or delisting findings, and recovery planning. The Service distributed informal guidance in May 2005 on the processing of 90-day petitions. Recovery plans generally must include recovery criteria that, when met, would result in the species being delisted. GAO examined three separate issues: (1) what types of decisions, if any, were excluded from the Service's review of decisions that may have been inappropriately influenced; (2) to what extent the Service's May 2005 informal guidance affected 90-day petition findings; and (3) to what extent the Service has, before delisting species, met recovery criteria. GAO interviewed Service staff, surveyed Service biologists, and reviewed delisting rules and …

Undocumented Aliens: Questions Persist about Their Impact on Hospitals' Uncompensated Care Costs
A letter report issued by the General Accounting Office with an abstract that begins "About 7 million undocumented aliens lived in the United States in 2000, according to Immigration and Naturalization Service estimates. Hospitals in states where many of them live report that treating them can be a financial burden. GAO was asked to examine the relationship between treating undocumented aliens and hospitals' costs not paid by patients or insurance. GAO was also asked to examine federal funding available to help hospitals offset costs of treating undocumented aliens and the responsibility of the Department of Homeland Security (Homeland Security) for covering medical expenses of sick or injured aliens encountered by Border Patrol and U.S. port-of-entry officials. To conduct this work, GAO surveyed 503 hospitals and interviewed Medicaid and hospital officials in 10 states. GAO also interviewed and obtained data from Homeland Security officials."

Fiscal Year 2014 Budget Request: U.S. Government Accountability Office
Testimony issued by the Government Accountability Office with an abstract that begins "In February, GAO submitted its fiscal year (FY) 2014 budget request for a modest increase of 1.9 percent to bolster its staff capacity and retain its highly skilled workforce. Consistent with guidance from the appropriations committees and OMB, the FY 2014 request was based on the annualized level of the initial continuing resolution (CR) which provided a slight increase over FY 2012 in FY 2013. Since that time, several actions have significantly reduced GAO's FY 2013 appropriation from $511.3 million in FY 2012 to $479.5 million in FY 2013, including 1) a reduction of $5 million imposed in the final CR resulting in an enacted level of $506.3 million, and 2) the $25.7 million sequester and $1 million rescission required by the Budget Control Act--a total reduction of $31.7 million or 6.2 percent below FY 2012."

Information Technology: Homeland Security Should Better Balance Need for System Integration Strategy with Spending for New and Enhanced Systems
A letter report issued by the General Accounting Office with an abstract that begins "The Department of Homeland Security (DHS) faces the daunting task of bringing together 22 diverse agencies to lead efforts to protect the homeland. Among the challenges posed by this transformation is integrating these agencies' diverse information technology (IT) systems: mission support, administration, and infrastructure (e.g., networks). GAO was asked to determine (1) whether DHS has defined its IT systems integration strategy and (2) how DHS is ensuring that IT investments made by component agencies (specifically focusing on the Federal Emergency Management Agency, the Transportation Security Administration, and the Coast Guard) are aligned with the department's strategic direction."

Federal Transit Administration: Progress and Challenges in Implementing and Evaluating the Job Access and Reverse Commute Program
A letter report issued by the Government Accountability Office with an abstract that begins "Established in 1998, the Job Access and Reverse Commute Program (JARC)-administered by the Federal Transit Administration (FTA)--awards grants to states and localities to provide transportation to help low-income individuals access jobs. In 2005, the Safe, Accountable, Flexible, Efficient Transportation Equity Act--A Legacy for Users (SAFETEA-LU) reauthorized the program and made changes, such as allocating funds by formula to large and small urban and rural areas through designated recipients, usually transit agencies and states. SAFETEA-LU also required GAO to periodically review the program. This second report under the mandate examines (1) the extent to which FTA has awarded JARC funds for fiscal years 2006 through 2008, and how recipients are using the funds; (2) challenges faced by recipients in implementing the program; and (3) FTA's plans to evaluate the program. For this work, GAO analyzed data and interviewed officials from FTA, nine states, and selected localities."

Telecommunications Networks: Addressing Potential Security Risks of Foreign-Manufactured Equipment
Testimony issued by the Government Accountability Office with an abstract that begins "The network providers and equipment manufacturers GAO spoke with reported taking steps in their security plans and procurement processes to ensure the integrity of parts and equipment obtained from foreign sources. Although these companies do not consider foreign-manufactured equipment to be their most pressing security threat, their brand image and profitability depend on providing secure, reliable service. In the absence of industry or government standards on the use of this equipment, companies have adopted a range of voluntary risk-management practices. These practices span the life cycle of equipment and cover areas such as selecting vendors, establishing vendor security requirements, and testing and monitoring equipment. Equipment that is considered critical to the functioning of the network is likely to be subject to more stringent security requirements, according to these companies. In addition to these efforts, companies are collaborating on the development of industry security standards and best practices and participating in information-sharing efforts within industry and with the federal government."

Defense Contracting: Post-Government Employment of Former DOD Officials Needs Greater Transparency
A letter report issued by the Government Accountability Office with an abstract that begins "Department of Defense (DOD) officials who serve in senior and acquisition positions and then leave for jobs with defense contractors are subject to the restrictions of post-government employment laws, in order to protect against conflicts of interest. Congress required GAO to report on employment of such officials by contractors who received more than $500 million in DOD's 2005 contract awards. In response, this report (1) provides information on how many former DOD employees worked for contractors in 2006 and estimates how many worked on contracts that were related to their former agencies or to their direct responsibilities and (2) identifies the practices used to monitor restrictions and information challenges in monitoring post-DOD employment. To do this work, GAO matched data from DOD for all employees who left DOD over a 6 year period with data from the Internal Revenue Service (IRS) and from 52 contractors; conducted surveys; and interviewed DOD and contractor officials."

Endangered Species Act: The U.S. Fish and Wildlife Service Has Incomplete Information about Effects on Listed Species from Section 7 Consultations
A letter report issued by the Government Accountability Office with an abstract that begins "The western United States, including vast stretches of federal land, is home to more than a third of the 1,317 species listed under the Endangered Species Act. Under section 7 of the act, federal agencies must ensure that any actions they authorize, fund, or carry out, whether on federal or private lands, do not jeopardize listed species. To fulfill this responsibility, the agencies often must formally consult with the Department of the Interior's U.S. Fish and Wildlife Service (Service), which issues a biological opinion assessing whether an action is likely to "take," or harm, a listed species. The Service may require the agencies to monitor and report on the action's effects on listed species, including take. For listed species subject to formal consultations in 11 western states, GAO was asked to examine the extent to which the Service tracks (1) required monitoring reports and (2) cumulative take. GAO reviewed the act, regulations, and policy and interviewed Service staff in all western states, reviewed 128 consultation files in five offices, and analyzed 23 listed species in detail."

Consumer Finance: Factors Affecting the Financial Literacy of Individuals with Limited English Proficiency
A letter report issued by the Government Accountability Office with an abstract that begins "According to Census data, more than 12 million adults in the United States report they do not speak English well or at all. Proficiency in reading, writing, speaking, and understanding the English language appears to be linked to multiple dimensions of adult life in the United States, including financial literacy--the ability to make informed judgments and take effective actions regarding the current and future use and management of money. The Credit Card Accountability, Responsibility and Disclosure Act of 2009 mandated GAO to examine the relationship between fluency in the English language and financial literacy. Responding to this mandate, this report examines the extent, if any, to which individuals with limited English proficiency are impeded in their financial literacy and conduct of financial affairs. To address this objective, GAO conducted a literature review of relevant studies, reports, and surveys, and conducted interviews at federal, nonprofit, and private entities that address financial literacy issues and serve people with limited English proficiency. GAO also conducted a series of focus groups with consumers and with staff at community and financial organizations. GAO makes no recommendations in this report."

Defense Infrastructure: Full Costs and Security Implications of Cheyenne Mountain Realignment Have Not Been Determined
Correspondence issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) built the Cheyenne Mountain Operations Center located near Colorado Springs, Colorado, in the early 1960s to withstand a multimegaton-yield-weapon strike and to provide protection against chemical and biological warfare. The mission of the Cheyenne Mountain Directorate is to monitor, process, and interpret air, missile, and space events that could threaten North America or have operational effects on U.S. forces or capabilities. This mission is conducted at five major centers--the Command Center, Air Warning, Missile Correlation, Operations Intelligence Watch, and Space Control--all currently located within Cheyenne Mountain. Elements of United States Strategic Command (USSTRATCOM) and Air Force Space Command are also located in Cheyenne Mountain. The Air Force's modernization of the attack warning systems within Cheyenne Mountain will cost more than $700 million from fiscal years 2000 through 2006. DOD officials have stated that they no longer need to continue operating in this hardened facility considering that the threat of an intercontinental ballistic missile strike in today's environment is low. In July 2006, the former Commander of NORAD and USNORTHCOM announced plans to move certain functions from Cheyenne Mountain and create an integrated command …

Information Security: TVA Needs to Address Weaknesses in Control Systems and Networks
A letter report issued by the Government Accountability Office with an abstract that begins "Securing the control systems that regulate the nation's critical infrastructures is vital to ensuring our economic security and public health and safety. The Tennessee Valley Authority (TVA), a federal corporation and the nation's largest public power company, generates and distributes power in an area of about 80,000 square miles in the southeastern United States. GAO was asked to determine whether TVA has implemented appropriate information security practices to protect its control systems. To do this, GAO examined the security practices in place at several TVA facilities; analyzed the agency's information security policies, plans, and procedures against federal law and guidance; and interviewed agency officials who are responsible for overseeing TVA's control systems and their security."
