Unemployed Older Workers: Many Face Long-Term Joblessness and Reduced Retirement Security

Testimony issued by the Government Accountability Office with an abstract that begins "Unemployment rates for workers of all ages have risen dramatically since the start of the recent recession in December 2007, and workers age 55 and over have faced particularly long periods of unemployment. The seasonally unadjusted unemployment rate for older workers increased from 3.1 percent in December 2007 to a high of 7.6 percent in February 2010, before it decreased to 6.0 percent in April 2012. As in prior recessions, smaller percentages of workers age 55 and over became unemployed in comparison with younger workers. Some researchers attribute older workers’ lower unemployment rates to the fact that older workers tend to have longer job tenure, and are consequently less likely to be laid off than younger workers."

HUD Has Identified Performance Measures for Its Block Grant Programs, but Information on Impact Is Limited

Correspondence issued by the Government Accountability Office with an abstract that begins "Information on the overall effectiveness (or impact) of the CDBG and HOME programs is limited. According to HUD officials, the agency has faced challenges in evaluating the impact of CDBG and HOME because, among other things, such an evaluation would have to compare neighborhoods that received program assistance with those that did not. Our previous work has also identified the difficulties of evaluating the impact of block grant programs that do not represent a uniform package of activities or desired outcomes across the country, as well as the common problem of attributing differences in communities’ outcomes to the effect of a program in the absence of controls for other explanations. As a result, few comprehensive studies on the impact of the CDBG and HOME programs exist, but studies that focused on specific activities have generally found that each of the programs has made positive contributions. We identified two studies that attempted to examine the overall impact of the CDBG program on communities, but both studies encountered evaluation challenges due to the program’s design. For example, a 1995 study that HUD considers the most comprehensive evaluation of CDBG suggests …

Defense Headquarters: DOD Needs to Periodically Review and Improve Visibility Of Combatant Commands' Resources

A letter report issued by the Government Accountability Office with an abstract that begins "GAO's analysis of resources devoted to the Department of Defense's (DOD) geographic combatant commands shows that authorized military and civilian positions and mission and headquarters-support costs have grown considerably over the last decade due to the addition of two new commands and increases in authorized positions at theater special operations commands. Data provided by the commands shows that authorized military and civilian positions increased by about 50 percent from fiscal years 2001 through 2012, to about 10,100 authorized positions. In addition, mission and headquarters support-costs at the combatant commands more than doubled from fiscal years 2007 through 2012, to about $1.1 billion. Both authorized military and civilian positions and mission and headquarters-support costs at the service component commands supporting the combatant commands also increased. Data on the number of personnel performing contract services across the combatant commands and service component commands varied or was unavailable, and thus trends could not be identified."

State Partnership Program: Improved Oversight, Guidance, and Training Needed for National Guard's Efforts with Foreign Partners

A letter report issued by the Government Accountability Office with an abstract that begins "Many State Partnership Program stakeholders, including State Partnership Program Coordinators, Bilateral Affairs Officers, and combatant command officials, cited benefits to the program, but the program lacks a comprehensive oversight framework that includes clear program goals, objectives, and metrics to measure progress against those goals, which limits the Department of Defense’s (DOD) and Congress’ ability to assess whether the program is an effective and efficient use of resources. The benefits described by all stakeholders focused on the program’s contributions to meeting their specific missions, such as building security relationships, providing experience to guardsmen, and supporting combatant commands’ missions. Goals, objectives, and metrics to measure progress are necessary for management oversight, and National Guard Bureau officials told GAO that they recognize the need to update the program’s goals and develop metrics and have initiated efforts in these areas. Officials expect completion of these efforts in summer 2012. Until program goals and metrics are implemented, DOD cannot fully assess or adequately oversee the program."

Temporary Assistance For Needy Families: Potential Options to Improve Performance and Oversight (open access)

Temporary Assistance For Needy Families: Potential Options to Improve Performance and Oversight

A letter report issued by the Government Accountability Office with an abstract that begins "Temporary Assistance for Needy Families' (TANF) role in providing cash assistance has evolved; fewer eligible families receive cash assistance and the composition of the caseload has changed. GAO noted in 2010 that 87 percent of the dramatic decline from 1995 through 2005 in the number of families receiving cash assistance was due a decline in eligible families participating in TANF, rather than increased incomes. Changes to state TANF programs, such as mandatory work requirements and lower benefits, account in part for this decline. Relatively modest caseload increases in recent years nationwide, as well as decreases in some states, have raised questions about TANF's responsiveness to changing economic conditions. GAO also reported in 2011 that the composition of the TANF caseload has changed, with about 40 percent of cases now comprised of children only, with the adult not receiving benefits, and little known nationwide about state policies for aiding these children. Potential options to better understand TANF's role as a cash assistance program may include: improving information on the extent to which states provide cash assistance to eligible low-income families, and requiring states to include more information--for …

Virtual Economies and Currencies: Additional IRS Guidance Could Reduce Tax Compliance Risks

A letter report issued by the Government Accountability Office with an abstract that begins "Transactions within virtual economies or using virtual currencies could produce taxable income in various ways, depending on the facts and circumstances of each transaction. For example, transactions within a "closed-flow" virtual currency system do not produce taxable income because a virtual currency can be used only to purchase virtual goods or services. An example of a closed-flow transaction is the purchase of items to use within an online game. In an "openflow" system, a taxpayer who receives virtual currency as payment for real goods or services may have earned taxable income since the virtual currency can be exchanged for real goods or services or readily exchanged for governmentissued currency, such as U.S. dollars."

Warfighter Support: Army Has Taken Steps to Improve Reset Process, but More Complete Reporting of Equipment and Future Costs Is Needed

A letter report issued by the Government Accountability Office with an abstract that begins "Since GAO’s 2007 review, the Army has taken steps to improve its use of reset in targeting equipment shortages. In 2007, GAO noted that the Army’s reset implementation strategy did not specifically target shortages of equipment on hand among units preparing for deployment to Iraq and Afghanistan in order to mitigate operational risk. GAO recommended that the Army act to ensure that its reset priorities address equipment shortages in the near term to ensure that the needs of deploying units could be met. The Department of Defense (DOD) did not concur, and stated that there was no need to reassess its approaches to equipment reset. However, in 2008, the Army issued its Depot Maintenance Enterprise Strategic Plan, noted that filling materiel shortages within warfighting units is a key challenge facing the depot maintenance enterprise, and called for changes in programs and policies to address materiel shortages within warfighting units. Further, recognizing that retrograde operations—the return of equipment from theater to the United States—are essential to facilitating depot level reset and redistribution of equipment, the Army in 2010 developed the retrograde, reset, and redistribution (R3) initiative to …

Combating Terrorism: State Should Enhance Its Performance Measures for Assessing Efforts in Pakistan to Counter Improvised Explosive Devices

A letter report issued by the Government Accountability Office with an abstract that begins "Multiple U.S. agencies and international partners are engaged in efforts to assist Pakistan in countering improvised explosive devices (IEDs) but face a variety of ongoing challenges. The agencies providing counter-IED assistance to Pakistan are primarily the Departments of State (State), Defense (DOD), Homeland Security (DHS), and Justice (DOJ). The following table identifies the types of assistance these U.S. agencies have provided and the corresponding objectives of Pakistan’s National Counter-IED Strategy. According to U.S. officials, U.S. agencies have encountered ongoing challenges to their efforts to assist Pakistan, such as delays in obtaining visas and in the delivery of equipment. U.S. officials have also identified broader challenges to Pakistan’s ability to counter IEDs, including the extreme difficulty of interdicting smugglers along its porous border with Afghanistan. In addition, though Pakistan developed a National Counter-IED Strategy in June 2011, it has yet to finalize an implementation plan for carrying out the strategy."

Veterans' Pension Benefits: Improvements Needed to Ensure Only Qualified Veterans and Survivors Receive Benefits

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Veterans Affairs’ (VA) pension program design and management do not adequately ensure that only veterans with financial need receive pension benefits. While the pension program is means tested, there is no prohibition on transferring assets prior to applying for benefits. Other means-tested programs, such as Medicaid, conduct a look-back review to determine if an individual has transferred assets at less than fair market value, and if so, may deny benefits for a period of time, known as the penalty period. This control helps ensure that only those in financial need receive benefits. In contrast, VA pension claimants can transfer assets for less than fair market value immediately prior to applying and be approved for benefits. For example, GAO identified a case where a claimant transferred over a million dollars less than 3 months prior to applying and was granted benefits. Also, VA’s process for assessing initial eligibility is inadequate in several key respects. The application form does not ask for some sources of income and assets such as private retirement income, annuities, and trusts. As a result, VA lacks complete information on a …

CRYSTALLINE CERAMIC WASTE FORMS: REFERENCE FORMULATION REPORT (open access)

CRYSTALLINE CERAMIC WASTE FORMS: REFERENCE FORMULATION REPORT

The research conducted in this work package is aimed at taking advantage of the long term thermodynamic stability of crystalline ceramics to create more durable waste forms (as compared to high level waste glass) in order to reduce the reliance on engineered and natural barrier systems. Durable ceramic waste forms that incorporate a wide range of radionuclides have the potential to broaden the available disposal options and to lower the storage and disposal costs associated with advanced fuel cycles. Assemblages of several titanate phases have been successfully demonstrated to incorporate radioactive waste elements, and the multiphase nature of these materials allows them to accommodate variation in the waste composition. Recent work has shown that they can be successfully produced from a melting and crystallization process. The objective of this report is to explain the design of ceramic host systems culminating in a reference ceramic formulation for use in subsequent studies on process optimization and melt property data assessment in support of FY13 melter demonstration testing. The waste stream used as the basis for the development and testing is a combination of the projected Cs/Sr separated stream, the Trivalent Actinide - Lanthanide Separation by Phosphorous reagent Extraction from Aqueous Komplexes (TALSPEAK) …

Recent T980 Crystal Collimation Studies at the Tevatron Exploiting a Pixel Detector System and a Multi-Strip Crystal Array

With the shutdown of the Tevatron, the T-980 crystal collimation experiment at Fermilab has been successfully completed. Results of dedicated beam studies in May 2011 are described in this paper. For these studies, two multi-strip crystals were installed in the vertical goniometer and an O-shaped crystal installed in a horizontal goniometer. A two-plane CMS pixel detector was also installed in order to enhance the experiment with the capability to image the profile of crystal channeled or multiple volume reflected beam. The experiment successfully imaged channeled beam from a crystal for 980-GeV protons for the first time. This new enhanced hardware yielded impressive results. The performance and characterization of the crystals studied have been very reproducible over time and consistent with simulations.

Studies of the structure and function of Mms6, a bacterial protein that promotes the formation of magnetic nanoparticles (open access)

Studies of the structure and function of Mms6, a bacterial protein that promotes the formation of magnetic nanoparticles

Here we report structural and functional studies of Mms6, a biomineralization protein that can promote the formation in vitro of magnetic nanoparticles with sizes and morphologies similar to the magnetites synthesized by magnetotactic bacteria. We found the binding pattern of Mms6 to ferric ion to be two-phase and multivalent. We quantatively determined that Mms6 binds one Fe{sup 3+} with a very high affinity (K{sub d} = 10{sup -16} M). The second phase of iron binding is multivalent and cooperative with respect to iron with a K{sub d} in the {mu}M range and a stoichiometry of about 20 ferric ion per protein molecule. We found that Mms6 exists in large particles of two sizes, one consisting of 20-40 monomeric units and the other of 200 units. From proteolytic digestion, ultracentrifugation and liposome fusion studies, we found that Mms6 forms a large micellar quaternary structure with the N-terminal domain self-assembling into a uniformly sized micelle and the C-terminal domain on the surface. The two-phase iron-binding pattern may be relevant to iron crystal formation. We propose that the first high affinity phase may stabilize a new conformation of the C-terminal domain that allows interaction with other C-terminal domains leading to a structural change …

Mesoporous silica nanoparticles as smart and safe devices for regulating blood biomolecule levels

Stimuli-responsive end-capped MSN materials are promising drug carriers that securely deliver a large payload of drug molecules without degradation or premature release. A general review of the recent progress in this field is presented, including a summary of a series of hard and soft caps for drug encapsulation and a variety of internal and external stimuli for controlled release of different therapeutics, a discussion of the biocompatibility of MSN both in vitro and in vivo, and a description of the sophisticated stimuli-responsive systems with novel capping agents and controlled release mechanism. The unique internal and external surfaces of MSN were utilized for the development of a glucose-responsive double delivery system end-capped with insulin. This unique system consists of functionalized MSNs capable of releasing insulin when the concentration of sugar in blood exceeds healthy levels. The insulin-free nanoparticles are then up taken by pancreatic cells, and release inside of them another biomolecule that stimulates the production of more insulin. The in vivo application of this system for the treatment of diabetes requires further understanding on the biological behaviors of these nanoparticles in blood vessels. The research presented in this dissertation demonstrated the size and surface effects on the interaction of MSNs …

Innovative Water Management Technology to Reduce Environment Impacts of Produced Water (open access)

Innovative Water Management Technology to Reduce Environment Impacts of Produced Water

Clemson University with Chevron as an industry partner developed and applied treatment technology using constructed wetland systems to decrease targeted constituents in simulated and actual produced waters to achieve reuse criteria and discharge limits. Pilot-scale and demonstration constructed wetland treatment system (CWTS) experiments led to design strategies for treating a variety of constituents of concern (COCs) in produced waters including divalent metals, metalloids, oil and grease, and ammonia. Targeted biogeochemical pathways for treatment of COCs in pilot-scale CWTS experiments included divalent metal sulfide precipitation through dissimilatory sulfate reduction, metal precipitation through oxidation, reduction of selenite to insoluble elemental selenium, aerobic biodegradation of oil, nitrification of ammonia to nitrate, denitrification of nitrate to nitrogen gas, separation of oil using an oilwater separator, and sorption of ammonia to zeolite. Treatment performance results indicated that CWTSs can be designed and built to promote specific environmental and geochemical conditions in order for targeted biogeochemical pathways to operate. The demonstration system successfully achieved consistent removal extents even while inflow concentrations of COCs in the produced water differed by orders of magnitude. Design strategies used in the pilot-scale and demonstration CWTSs to promote specific conditions that can be applied to designing full-scale CWTSs include plant and …

Pore-fluid effects on seismic waves in vertically fractured earth with orthotropic symmetry (open access)

Pore-fluid effects on seismic waves in vertically fractured earth with orthotropic symmetry

For elastically noninteracting vertical-fracture sets at arbitrary orientation angles to each other, a detailed model is presented in which the resulting anisotropic fractured medium generally has orthorhombic symmetry overall. Some of the analysis methods and ideas of Schoenberg are emphasized, together with their connections to other similarly motivated and conceptually related methods by Sayers and Kachanov, among others. Examples show how parallel vertical-fracture sets having HTI (horizontal transversely isotropic) symmetry transform into orthotropic fractured media if some subsets of the vertical fractures are misaligned with the others, and then the fractured system can have VTI (vertical transversely isotropic) symmetry if all of the fractures are aligned randomly or half parallel and half perpendicular to a given vertical plane. An orthotropic example having vertical fractures in an otherwise VTI earth system (studied previously by Schoenberg and Helbig) is compared with the other examples treated and it is finally shown how fluids in the fractures affect the orthotropic poroelastic system response to seismic waves. The key result is that fracture-influence parameters are multiplied by a factor of (1-B), where 0 {le} B < 1 is Skempton's second coefficient for poroelastic media. Skempton's B coefficient is itself a measurable characteristic of fluid-saturated porous …
