Workshop on photon activation therapy: proceedings
This Workshop was held concurrently with an IAEA Research Coordination Meeting on Exploration of the Possibility of High-LET Radiation for Non-conventional Radiotherapy in Cancer. The Workshop on Photon Activation Therapy (PAT) was given as a special session on April 18, as it was thoght PAT might eventually be found to be attractive to developing countries, which is a major concern of the IAEA. An effort was made to bring together representatives of the various groups known to be actively working on PAT; these included investigators from Sweden and Japan as well as the US. It is hoped that this compendium of papers will be of use to those currently active in this developing field, as well as to those who might join this area of endeavor in the future.

Silver isotopic anomalies in iron meteorites: cosmic-ray production and other possible sources
The sources of excess /sup 107/Ag observed in iron meteorites by Kaiser, Kelly, and Wasserburg (1980) are examined, with emphasis on the reactions of cosmic-ray particles with palladium. The cross sections for the production of the silver isotopes from palladium by energetic cosmic-ray particles are evaluated or estimated and used to calculate spallogenic production rates relative to that of /sup 53/Mn from iron. The upper limit for the production rate of excess /sup 107/Ag by galactic-cosmic-ray particles is 400 atoms/min/kg(Pd) which, over an exposure age of 10/sup 9/ years, would make only 1% of the observed excesses of /sup 107/Ag. Neutron-capture reactions with Pd isotopes produce mainly /sup 109/Ag. Binary fission of a siderophilic superheavy element would be expected to yield more /sup 109/Ag than /sup 107/Ag. An intense proton irradiation in the early solar system probably would produce a lower ratio of (/sup 107/Pd//sup 108/Pd) to (/sup 26/Al//sup 27/Al) than observed in meteorites. Therefore the presence of excess /sup 107/Ag in iron meteorites with large Pd/Ag ratios very likely is due to the incorporation of 6.5 x 10/sup 6/-year /sup 107/Pd of nucleosynthetic origin in these meteorites.

Calculation of Departure From Nucleate Boiling Conditions for the Spert Iii Reactor in the High Pressure Region
Calculations are made to determine the safe steadystate power operating limits of the Spert III reactor from the viewpoint of fuel plate burnout. A computer program is developed for the IBM 704 to aid in these calculations. The Bettis design departure from nucleate boiling (DNB) equation is used in conjunction with the LeTourneau and Grimble method of hot channel'' analysis in the development of the calculations. For cases where DNB occurs in the bulk boiling region, a modified Martinelli-Nelson twophase flow correlation and some experimental singlephase pressure drop data are employed. DNB for a typical operating condition of 550 deg F inlet temperature and 2500 psig is computed to check the code. The results of the sample calculation show that at a steady- state power level of 60 Mw (maximum design power) the minimum flow rate required to prevent DNB is approximately 8000 gpm. (auth)

Securities And Exchange Commission: Continued Management Attention Would Strengthen Internal Supervisory Controls
A letter report issued by the Government Accountability Office with an abstract that begins "After the passage of the Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank Act) in 2010, the Securities and Exchange Commission's (SEC) Office of Compliance Inspections and Examinations, Division of Corporation Finance, and Division of Enforcement (herein "the offices") established a working group that developed an internal supervisory control framework. Internal supervisory controls include the processes established by management to help ensure that procedures applicable to staff are performed completely, consistent with applicable policies and procedures, and remain current. The overall control framework is generally consistent with federal internal control standards, which includes identifying and assessing risks, identifying and assessing internal controls, and reporting the results of testing to management and Congress."

Specialty Hospitals: Information on National Market Share, Physician Ownership, and Patients Served
Correspondence issued by the General Accounting Office with an abstract that begins "Specialty hospitals represent a small but growing segment of the health care industry. These hospitals specialize in providing care for certain conditions, such as cardiac care, or performing certain procedures, such as orthopedic surgery. Specialty hospitals are not an entirely new phenomenon, as children's and other types of specialty hospitals have existed for decades. Consequently, it is challenging to distinguish between the old and new types of specialty hospitals. One aspect that sets apart the newer genre of specialty hospitals is that many are owned, in part, by the physicians who work in them. Advocates contend that, because of their focused mission, specialty hospitals can provide high-quality specialty services more efficiently than general hospitals. Because specialty hospitals can tailor their facilities and resources to best fit the needs of certain types of patients, individuals treated in such hospitals may enjoy relatively greater convenience and comfort. Specialty hospitals may also offer physicians financial and work environment advantages. Advocates have stated that the focused mission and dedicated resources of specialty hospitals allow physicians to treat more patients than they could in general hospitals. Physicians may gain financially from this increased …

Management Report: Improvements Are Needed in Internal Control Over Financial Reporting for the Troubled Asset Relief Program
Correspondence issued by the Government Accountability Office with an abstract that begins "The Emergency Economic Stabilization Act of 2008 (EESA) requires that we annually audit the financial statements of the Troubled Asset Relief Program (TARP), which is implemented by the Office of Financial Stability (OFS). On November 15, 2010, we issued our audit report including (1) an unqualified opinion on OFS's financial statements for TARP as of and for the fiscal years ended September 30, 2010, and 2009, and (2) an opinion that OFS maintained effective internal control over financial reporting as of September 30, 2010. We also reported that our tests of OFS's compliance with selected provisions of laws and regulations for the fiscal year ended September 30, 2010, disclosed no instances of noncompliance. Our November 2010 audit report concluded that although certain internal controls could be improved, OFS maintained, in all material respects, effective internal control over financial reporting as of September 30, 2010, that provided reasonable assurance that misstatements, losses, or noncompliance material in relation to the financial statements would be prevented or detected and corrected on a timely basis. Our audit report also identified a significant deficiency in OFS's internal control over its accounting and financial …

DOD Personnel: DOD Comments on GAO's Report on DOD's Civilian Human Capital Strategic Planning
Correspondence issued by the General Accounting Office with an abstract that begins "In response to a Congressional request, we issued a report in March 2003 on the Department of Defense's (DOD) strategic planning efforts for civilian personnel at DOD and selected defense components, including the four military services and two defense agencies. In that report we made recommendations to the Secretary of Defense to strengthen civilian human capital planning, including integration with military personnel and sourcing initiatives. DOD's response to our March 2003 report and recommendations were received too late to be included in that report. To provide our perspective on DOD's comments, we briefly summarize our March 2003 report's objectives, results, and recommendations and DOD's comments, along with our evaluation of the comments. DOD's civilian employees play key roles in such areas as defense policy, intelligence, finance, acquisitions, and weapon systems maintenance. Although downsized 38 percent between fiscal years 1989 and 2002, this workforce has taken on greater roles as a result of DOD's restructuring and transformation. Responding to congressional concerns about the quality and quantity of, and the strategic planning for, the civilian workforce, we determined the following for DOD, the military services, and selected defense agencies (the …

Medicare Imaging Accreditation: Effect on Access to Advanced Diagnostic Imaging Is Unclear amid Other Policy Changes
A letter report issued by the Government Accountability Office with an abstract that begins "GAO found that the number of advanced diagnostic imaging (ADI) services provided to Medicare beneficiaries in the office setting—an indicator of access to those services—began declining before and continued declining after the accreditation requirement went into effect on January 1, 2012. In particular, the rate of decline from 2009 to 2010 was similar to the rate from 2011 to 2012 for magnetic resonance imaging (MRI); computed tomography (CT); and nuclear medicine (NM), including positron emission tomography (PET) services. These results suggest that the overall decline was driven, at least in part, by factors other than accreditation. The percentage decline in the number of ADI services provided in the office setting was generally similar in both urban and rural areas during the period GAO studied."

Defense Space Activities: Organizational Changes Initiated, but Further Management Actions Needed
A letter report issued by the General Accounting Office with an abstract that begins "In January 2001, the congressionally chartered Commission to Assess United States National Security Space Management and Organization--known as the Space Commission--reported that the Department of Defense (DOD) lacked the senior-level focus and accountability to provide guidance and oversight for national security space operations. Congress mandated that GAO provide an assessment of DOD's actions to implement the Space Commission's recommendations. Thus, GAO (1) updated its June 2002 assessment of DOD's actions to address the Space Commission's recommendations, (2) ascertained progress in addressing other long- term management concerns, and (3) assessed the extent to which DOD has developed a results-oriented management framework for space activities."

Elections: All Levels of Government Are Needed to Address Electronic Voting System Challenges
Testimony issued by the Government Accountability Office with an abstract that begins "Since the 2000 national elections, concerns have been raised by various groups regarding the election process, including voting technologies. Beginning in 2001, GAO published a series of reports examining virtually every aspect of the elections process. GAO's complement of reports was used by Congress in framing the Help America Vote Act of 2002, which, among other things, provided for replacement of older voting equipment with more modern electronic voting systems and established the Election Assistance Commission (EAC) to lead the nation's election reform efforts. GAO's later reports have raised concerns about the security and reliability of these electronic voting systems, examined the EAC's efforts to address these concerns, and surveyed state and local officials about practices used during the 2004 election, as well as plans for their systems for the 2006 election. Using its published work on electronic voting systems, GAO was asked to testify on (1) the contextual role and characteristics of electronic voting systems, (2) the range of security and reliability concerns that have been reported about these systems, (3) the experiences and management practices of states and local jurisdictions regarding these systems, and (4) the …

Defense Infrastructure: Improved Guidance Needed for Estimating Alternatively Financed Project Liabilities
A letter report issued by the Government Accountability Office with an abstract that begins "In the event of future base closure, the Department of Defense's (DOD) potential financial liabilities from alternatively financed projects will vary by project type and the language of its legal agreements. According to GAO's analysis of data reported by DOD, it had more than 550 such projects on more than 240 U.S. installations, as of September 30, 2011. 56 percent of these projects have been put in place since the 2005 Base Realignment and Closure (BRAC) round. Further, according to this analysis and GAO's case study review, liabilities will likely exist for renewable energy and privatized utility projects in the event of base closure because these projects commit the government to making future payments, although the liabilities may be limited by termination for convenience clauses in agreements. In contrast, privatized housing, privatized army lodging, and enhanced use lease projects are generally not expected to create a financial liability if bases close because DOD does not expect to terminate these types of agreements."

Aviation Fees: Review of Air Carriers' Year 2000 Passenger and Property Screening Costs
A letter report issued by the Government Accountability Office with an abstract that begins "The Aviation and Transportation Security Act (ATSA) authorized the Transportation Security Administration (TSA) to impose an Aviation Security Infrastructure Fee (ASIF) on air carriers to help pay for the costs of aviation security services. To impose the ASIF, TSA issued an Interim Final Rule (IFR) and required air carriers to report their passenger and property screening costs incurred in 2000 on an attachment to the IFR referred to as Appendix A. The 2000 screening costs reported by air carriers were going to be used to establish the ASIF. Based on industry estimates of $1 billion, TSA had estimated that the costs incurred by air carriers in 2000 were $750 million, but the amounts reported by air carriers totaled $319 million, significantly less than expected. To provide the Congress with an independent assessment, the Department of Homeland Security Appropriations Act, 2005 required GAO to review the amount of passenger and property screening costs incurred by air carriers in 2000."

Bureau of the Public Debt: Areas for Improvement in Information Security Controls
Correspondence issued by the Government Accountability Office with an abstract that begins "In connection with fulfilling our requirement to audit the financial statements of the U.S. government, we audited and reported on the Schedules of Federal Debt Managed by the Bureau of the Public Debt (BPD) for the fiscal years ended September 30, 2004 and 2003. As part of these audits, we performed a review of the general and application information security controls over key BPD financial systems. As we reported in connection with our audit of the Schedules of Federal Debt for the fiscal years ended September 30, 2004 and 2003, BPD maintained, in all material respects, effective internal control, including general and application information security controls, relevant to the Schedule of Federal Debt related to financial reporting and compliance with applicable laws and regulations as of September 30, 2004, that provided reasonable assurance that misstatements, losses, or noncompliance material in relation to the Schedule of Federal Debt would be prevented or detected on a timely basis. We found matters involving information security controls that we do not consider to be reportable conditions, but that nevertheless warrant BPD management's attention and action.

Satellite Control: Long-Term Planning and Adoption of Commercial Practices Could Improve DOD's Operations
A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) satellite control networks are fragmented and potentially duplicative. Over the past decade, DOD has increasingly deployed standalone satellite control operations networks, which are designed to operate a single satellite system, as opposed to shared systems that can operate multiple kinds of satellites. Dedicated networks can offer many benefits to programs, including possible lower risks and customization for a particular program's needs. However, they can also be more costly and have led to a fragmented, and potentially duplicative, approach which requires more infrastructure and personnel than shared operations. For example, one Air Force base has 10 satellite programs operated by 8 separate control centers. According to Air Force officials, DOD continues to acquire standalone networks and has not worked to move its current standalone operations towards a shared satellite control network, which could better leverage DOD investments."

No Child Left Behind Act: Education Actions May Help Improve Implementation and Evaluation of Supplemental Educational Services
Testimony issued by the Government Accountability Office with an abstract that begins "The No Child Left Behind Act (NCLBA) requires districts with schools that receive Title I funds and that have not met state performance goals for 3 consecutive years to offer low-income students supplemental educational services (SES), such as tutoring. This testimony discusses early implementation of SES, including how (1) SES participation changed in recent years; (2) providers work with districts to deliver services; (3) states monitor and evaluate SES; and (4) the U.S. Department of Education (Education) monitors and supports SES implementation. This testimony is based on an August 2006 report (GAO-06-758) and also provides information on actions Education has taken that respond to our recommendations. For the report, GAO surveyed all states and a nationally representative sample of districts with schools required to offer SES, visited four school districts, and interviewed SES providers."

Tobacco Taxes: Large Disparities in Rates for Smoking Products Trigger Significant Market Shifts to Avoid Higher Taxes
A letter report issued by the Government Accountability Office with an abstract that begins "Large federal excise tax disparities among tobacco products, which resulted from the Childrens Health Insurance Program Reauthorization Act (CHIPRA) of 2009, created opportunities for tax avoidance and led to significant market shifts by manufacturers and price sensitive consumers toward the lower-taxed products. Monthly sales of pipe tobacco increased from approximately 240,000 pounds in January 2009 to over 3 million pounds in September 2011, while roll-your-own tobacco dropped from about 2 million pounds to 315,000 pounds. For the same months, large cigar sales increased from 411 million to over 1 billion cigars, while small cigars dropped from about 430 million to 60 million cigars. According to government, industry, and nongovernmental organization representatives, many roll-your-own tobacco and small cigar manufacturers shifted to the lower-taxed products after CHIPRA to avoid paying higher taxes."
