A letter report issued by the Government Accountability Office with an abstract that begins "Market participants indicated that primary market disclosure for municipal securities—official statements—generally provides useful information, but investors and market participants cited a number of limitations to continuing disclosures. The most frequently cited limitations were timeliness, frequency, and completeness. For example, investors and other market participants said that issuers do not always provide all the financial information, event notices, or other information they pledged to provide for the lifetime of a security. While GAO's analysis of current regulatory requirements for municipal securities disclosure found that they largely reflected the seven principles of effective disclosure, regulators and market participants said that there are some limitations on the enforceability and efficiency of the regulations. However, the effect of these limitations on individual investors largely is unknown because limited information exists about the extent to which individual investors use disclosures to make investment decisions. Nevertheless, regulators remain concerned about this market, in part due to its size and the participation of individual investors. As discussed below, the Securities and Exchange Commission (SEC) and Municipal Securities Rulemaking Board (MSRB) have been taking or plan to take actions to improve disclosure."

A total of 58 urine samples and 10 fecal samples were submitted during the report period (April 1, 2009 through March 31, 2010) to General Engineering Laboratories, South Carolina by the Hanford Internal Dosimetry Program (IDP) to check the accuracy, precision, and detection levels of their analyses. Urine analyses for Sr, 238Pu, 239Pu, 241Am, 243Am 235U, 238U, elemental uranium and fecal analyses for 241Am, 238Pu and 239Pu were tested this year as well as four tissue samples for 238Pu, 239Pu, 241Am and 241Pu. The number of QC urine samples submitted during the report period represented 1.3% of the total samples submitted. In addition to the samples provided by IDP, GEL was also required to conduct their own QC program, and submit the results of analyses to IDP. About 33% of the analyses processed by GEL during the third year of this contract were quality control samples. GEL tested the performance of 21 radioisotopes, all of which met or exceeded the specifications in the Statement of Work within statistical uncertainty (Table 4).

A total of 76 urine samples and 10 spiked fecal samples were submitted during the report period (April 1, 2010 through March 31, 2011) to GEL Laboratories, LLC in South Carolina by the Hanford Internal Dosimetry Program (IDP) to check the accuracy, precision, and detection levels of their analyses. Urine analyses for 14C, Sr, for 238Pu, 239Pu, 241Am, 243Am, 235U, 238U, 238U-mass and fecal analyses for 241Am, 238Pu and 239Pu were tested this year. The number of QC urine samples submitted during the report period represented 1.1% of the total samples submitted. In addition to the samples provided by IDP, GEL was also required to conduct their own QC program, and submit the results of analyses to IDP. About 31% of the analyses processed by GEL during the first year of contract 112512 were quality control samples. GEL tested the performance of 23 radioisotopes, all of which met or exceeded the specifications in the Statement of Work within statistical uncertainty except the slightly elevated relative bias for 243,244Cm (Table 4).

A letter report issued by the Government Accountability Office with an abstract that begins "Over the last decade, working women’s access to and participation in employer-sponsored retirement plans have improved relative to men. Indeed, from 1998 to 2009, women surpassed men in their likelihood of working for an employer that offered a pension plan, largely because the proportion of men covered by a plan declined. Furthermore, as employers have continued to terminate their defined benefit (DB) plans and have switched to defined contribution (DC) plans, the proportion of women who worked for employers that offered a DC plan increased. Correspondingly, women’s participation rates in DC plans increased slightly over this same period while men’s participation fell, thereby narrowing the participation difference between men and women to 1 percentage point. At the same time, however, women contributed to their DC plans at lower levels than men."

Correspondence issued by the Government Accountability Office with an abstract that begins "Based on our analysis, none of the five MDA schedules we reviewed fully met all nine of the schedule best practices, including the practice of capturing all activities. The schedules were inconsistent in meeting best practices, and some had major deficiencies. These results are significant because a reliable schedule is one key factor that indicates a program is likely to achieve its planned outcomes. Our analysis suggests that estimated time frames and costs of these programs are either not reliable or the program is missing information that could make it more efficient. The MDA schedule results are similar to those of other agencies that GAO has analyzed. We are recommending actions that would better ensure compliance with schedule best practices for the five programs reviewed as well as for the long-term MDA program. The Department of Defense (DOD) concurred with our recommendations."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of the Treasury announced changes in January 2012 to its Making Home Affordable (MHA) programs, which are funded by the Troubled Asset Relief Program (TARP), to address barriers to borrower participation. These changes include expanding eligibility criteria and extending application deadlines through 2013. Not enough time has passed to assess the extent to which these changes will increase participation. Several large servicers were not able to fully implement the changes by the June 1, 2012, effective date, and servicers that GAO queried had mixed views about possible effects. Treasury consulted with servicers, investors, and federal banking regulators before implementing the changes but did not perform a comprehensive risk assessment for the changes or develop meaningful performance measures in accordance with standards for internal control. As a result, Treasury may have difficulty mitigating potential risks, such as an increase in redefaults or the misuse of funds; effectively assessing program outcomes; or holding servicers accountable."

A letter report issued by the Government Accountability Office with an abstract that begins "GAO earlier reported that unmanned aircraft systems (UAS) could not meet the aviation safety requirements developed for manned aircraft and posed several obstacles to operating safely and routinely in the national airspace system. These include 1) the inability for UAS to detect, sense, and avoid other aircraft and airborne objects in a manner similar to “see and avoid” by a pilot in a manned aircraft; 2) vulnerabilities in the command and control of UAS operations; 3) the lack of technological and operational standards needed to guide the safe and consistent performance of UAS; and 4) the lack of final regulations to accelerate the safe integration of UAS into the national airspace. GAO stated in 2008 that Congress should consider creating an overarching body within the Federal Aviation Administration (FAA) to address obstacles for routine access. FAA’s Joint Planning and Development Office (JPDO) has taken on a similar role. FAA has implemented GAO’s two recommendations related to its planning and data analysis efforts to facilitate integration."

Testimony issued by the Government Accountability Office with an abstract that begins "In summary, TSA has completed its initial testing of the CAT/BPSS technology and has begun operational testing at three airports. We found the project’s associated life cycle cost estimate to be reasonably comprehensive and well documented, although we are less confident in its accuracy due to questions about the assumed inflation rate. In addition, we could not evaluate its credibility because the current version does not include an independent cost estimate or an assessment of how changing key assumptions and other factors would affect the estimate. Our past work has identified three key challenges related to TSA’s efforts to acquire and deploy technologies to address homeland security needs: (1) developing and meeting technology program requirements, (2) overseeing and conducting testing of new screening technologies, and (3) developing acquisition program baselines to establish initial cost, schedule, and performance parameters."

The closure of Tank 16H will require removal of material from the annulus of the tank. Samples from Tank 16H annulus were characterized and tested to provide information to evaluate various alternatives for removing the annulus waste. The analysis found all four annulus samples to be composed mainly of Si, Na, and Al and lesser amounts of other elements. The XRD data indicate quartz (SiO{sub 2}) and sodium aluminum nitrate silicate hydrate (Na{sub 8}(Al{sub 6}Si{sub 6}O{sub 24})(NO{sub 3}){sub 2}.4H{sub 2}O) as the predominant crystalline mineral phases in the samples. The XRD data also indicate the presence of crystalline sodium nitrate (NaNO{sub 3}), sodium nitrite (NaNO{sub 2}), gibbsite (Al(OH){sub 3}), hydrated sodium bicarbonate (Na{sub 3}H(CO{sub 3}){sub 2}.2H{sub 2}O), and muscovite (KAl{sub 2}(AlSi{sub 3}O{sub 10})(OH){sub 2}). Based on the weight of solids remaining at the end of the test, the water leaching test results indicate 20-35% of the solids dissolved after three contacts with an approximately 3:1 volume of water at 45 C. The chemical analysis of the leachates and the XRD results of the remaining solids indicate sodium salts of nitrate, nitrite, sulfate, and possibly carbonate/bicarbonate make up the majority of the dissolved material. The majority of these salts were dissolved …

This report discusses factors suggesting an increased risk of a double-dip recession. A double-dip or W-shaped recession occurs when the economy emerges from a recession, has a short period of growth, but then, still well short of a full recovery, falls back into recession. It also discusses other factors that suggest economic recovery will continue. It presents the U.S. historical experience with double-dip recessions. It examines the role of deleveraging by households and businesses in the aftermath of the recent financial crisis in shaping the likely pace of economic recovery. The report concludes with a look at current economic projections.

A letter report issued by the Government Accountability Office with an abstract that begins "GAO’s analysis of Marine Corps depot maintenance activity group (DMAG) reports showed that from fiscal years 2004 through 2011, reported actual carryover exceeded the allowable amounts in the most recent 6 years of the 8- year period, ranging from $59 million in fiscal year 2007 to $7 million in fiscal year 2011. GAO’s analysis also showed that the amounts of carryover exceeding the allowable amounts have declined in each of the past 4 years. These reductions could be attributed to DMAG actions, including implementing production efficiencies that reduced the time required to repair weapon systems."

A letter report issued by the Government Accountability Office with an abstract that begins "The Social Security Administration (SSA) has taken steps that hold promise for improving the process for updating its medical criteria, but continues to face challenges ensuring timely updates. SSA now uses a two-tiered system for ongoing revisions to its medical listings. First, it completes a comprehensive review of all medical conditions listed within each of 14 body systems, making needed revisions. For subsequent updates for a body system, the agency uses a targeted approach, selecting for review and revision only those medical conditions most in need of change. To date, SSA has completed comprehensive revisions for 8 of the 14 body systems and now is reviewing conditions under them to determine where targeted revisions are appropriate. However, some of these targeted revisions have experienced delays. Moreover, SSA has yet to complete comprehensive revisions for six body systems that have been ongoing for 19 to 33 years. SSA officials attributed delays to a lack of staff and expertise, along with the complexity and unpredictability of the regulatory process."

The U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office operates the Nevada National Security Site (NNSS) and North Las Vegas Facility (NLVF). From 1951 through 1992, the NNSS was the continental testing location for U.S. nuclear weapons. The release of radionuclides from NNSS activities has been monitored since the initiation of atmospheric testing. Limitation to underground detonations after 1962 greatly reduced radiation exposure to the public surrounding the NNSS. After nuclear testing ended in 1992, NNSS radiation monitoring focused on detecting airborne radionuclides from historically contaminated soils. These radionuclides are derived from re-suspension of soil (primarily by wind) and emission of tritium-contaminated soil moisture through evapotranspiration. Low amounts of legacy-related tritium are also emitted to air at the NLVF, an NNSS support complex in North Las Vegas. To protect the public from harmful levels of man-made radiation, the Clean Air Act, National Emission Standards for Hazardous Air Pollutants (NESHAP) (Title 40 Code of Federal Regulations [CFR] Part 61 Subpart H) limits the release of radioactivity from a U.S. Department of Energy (DOE) facility to that which would cause 10 millirem per year (mrem/yr) effective dose equivalent to any member of the public. This limit does not include …

This report discusses section 123 of the Atomic Energy Act (AEA), the specific requirements of which must be met in order for the United States to engage in civilian nuclear cooperation with other states. The AEA also provides for exemptions to these requirements, export control licensing procedures, and criteria for terminating cooperation.

Control of collective properties of relativistic particles is increasingly important in modern accelerators. In particular, shot noise affects accelerator performance by driving instabilities or by competing with coherent processes. We present experimental observations of shot noise suppression in a relativistic beam at the Linac Coherent Light Source. By adjusting the dispersive strength of a chicane, we observe a decrease in the optical transition radiation emitted from a downstream foil. We show agreement between the experimental results, theoretical models, and 3D particle simulations.
