This report discusses two broad policy options for Congress as it considers reauthorizing federal surface transportation programs.

A letter report issued by the Government Accountability Office with an abstract that begins "The U.S. Agency for International Development (USAID) reduces the average delivery time frame for emergency food aid by prepositioning food domestically—that is, in warehouses in the United States—and overseas. GAO estimates that compared with USAID's standard shipping process, which can take several months, prepositioning food aid shortened delivery time frames by an average of almost a month for shipments to the World Food Program (WFP). GAO also estimates that prepositioning shortened delivery time frames by an average of more than 2 months for other organizations—“cooperating sponsors”—that receive USAID grants. In addition, USAID reduces delivery time frames when it diverts shipments en route to overseas prepositioning warehouses to areas with immediate needs. For all cooperating sponsors, GAO estimates that diversions saved, on average, about 2 months."

A letter report issued by the Government Accountability Office with an abstract that begins "According to the Department of Homeland Security (DHS), there are thousands of facilities in the United States that if destroyed by a disaster could cause casualties, economic losses, or disruptions to national security. The Homeland Security Act of 2002 gave DHS responsibility for leading and coordinating the nation's effort to protect critical infrastructure and key resources (CIKR). Homeland Security Presidential Directive 7 (HSPD-7) defined responsibilities for DHS and certain federal agencies--known as sector-specific agencies (SSAs)--that represent 18 industry sectors, such as energy. In accordance with the Homeland Security Act and HSPD-7, DHS issued the National Infrastructure Protection Plan (NIPP) in June 2006 to provide the approach for integrating the nation's CIKR. GAO was asked to study DHS's January 2009 revisions to the NIPP in light of a debate over whether DHS has emphasized protection--to deter threats, mitigate vulnerabilities, or minimize the consequences of disasters---rather than resilience---to resist, absorb, or successfully adapt, respond to, or recover from disasters. This report discusses (1) how the 2009 NIPP changed compared to the 2006 NIPP and (2) how DHS and SSAs addressed resiliency as part of their planning efforts. GAO …

A letter report issued by the Government Accountability Office with an abstract that begins "Three of the nine selected agencies' risk assessment methodologies that GAO reviewed—the Department of Energy (DOE), the Department of Justice (DOJ), and the Department of State (State)—fully align with the Interagency Security Committee's (ISC) risk assessment standards, but six do not—the Department of the Interior (DOI), the Department of Veterans Affairs (VA), the Federal Protective Service (FPS), the Federal Emergency Management Agency (FEMA), the Nuclear Regulatory Commission (NRC), and the Office of Personnel Management (OPM). As a result, these six agencies may not have a complete understanding of the risks facing approximately 52,000 federal facilities and may be less able to allocate security resources cost-effectively at the individual facility level or across the agencies' facility portfolios. ISC's The Risk Management Process for Federal Facilities ( RMP ) standard requires that agencies' facility risk assessment methodologies must (1) consider all of the undesirable events identified in the RMP as possible risks to federal facilities, and (2) assess the threat, consequences, and vulnerability to specific undesirable events. Six of the nine agencies' methodologies GAO reviewed do not align with ISC's standards because the methodologies do not (1) consider …

A letter report issued by the Government Accountability Office with an abstract that begins "The Departments of Defense (DOD), Labor (DOL), and Veterans Affairs (VA) have implemented most of the key components of the Transition Assistance Program (TAP), a gateway to information and services available to servicemembers transitioning to civilian life. However, the agencies are still in the process of implementing other key components of TAP. While originally planned for October 2013, agencies now plan to implement virtually all components by the end of March 2014, with full implementation expected by June 2014."

A letter report issued by the Government Accountability Office with an abstract that begins "Based on available data, about 14 percent of small employers sponsor some type of retirement plan. Overall, GAO found that the likelihood that a small employer will sponsor a retirement plan largely depends on the size of the employer’s workforce and the workers’ average wages more than on the industry in which the employer operates and the geographic region in which the employer is located. GAO found the greatest likelihood of plan sponsorship was among small employers with larger numbers of employees and those paying an average annual wage of $50,000 to $99,999. GAO also found that the most common plans sponsored by small employers are 401(k)s and Savings Incentive Match Plans for Employees (SIMPLE) Individual Retirement Arrangements (IRA)—an employer-sponsored IRA designed for small employers—at 46 percent and 40 percent, respectively, of total plans. However, IRS currently does not have the means to collect information on employers that sponsor another type of IRA plan designed for small employers, the Simplified Employee Pension (SEP) IRA plan, which limits what is known about employers that sponsor these plans."

A letter report issued by the Government Accountability Office with an abstract that begins "In response to the ongoing threats to federal systems and operations posed by cyber attacks, President Bush established the Comprehensive National Cybersecurity Initiative (CNCI) in 2008. This initiative consists of a set of projects aimed at reducing vulnerabilities, protecting against intrusions, and anticipating future threats. GAO was asked to determine (1) what actions have been taken to develop interagency mechanisms to plan and coordinate CNCI activities and (2) what challenges CNCI faces in achieving its objectives related to securing federal information systems. To do this, GAO reviewed CNCI plans, policies, and other documentation and interviewed officials at the Office of Management and Budget (OMB), Department of Homeland Security, and the Office of the Director of National Intelligence (ODNI), among other agencies. GAO also reviewed studies examining aspects of federal cybersecurity and interviewed recognized cybersecurity experts."

A letter report issued by the Government Accountability Office with an abstract that begins "American consumers, businesses, and federal agencies rely on the Energy Star program to identify products that decrease greenhouse emissions and lower energy costs. In addition, the federal government and various states offer tax credits and other incentives to encourage the use of energy-efficient products including Energy Star products. Specifically, approximately $300 million from the American Recovery and Reinvestment Act will be used for state rebate programs on energy-efficient products. The Energy Star program, which began in 1992, is overseen jointly by the U.S. Department of Energy (DOE) and the U.S. Environmental Protection Agency (EPA). Given the millions of dollars allocated to encourage use of Energy Star products and concerns that the Energy Star program is vulnerable to fraud and abuse, GAO was asked to conduct proactive testing to (1) obtain Energy Star partnership status for bogus companies and (2) submit fictitious products for Energy Star certification. To perform this investigation, GAO used four bogus manufacturing firms and fictitious individuals to apply for Energy Star partnership and submitted 20 fictitious products with fake energy-savings claims for Energy Star certification. GAO also reviewed program documents and interviewed agency …

Samples have been prepared from a 9975 lower fiberboard subassembly fabricated from softwood fiberboard. Physical, mechanical and thermal properties have been measured following varying periods of conditioning in each of several environments. These tests have been conducted in the same manner as previous testing on cane fiberboard samples. Overall, similar aging trends are observed for softwood and cane fiberboard samples, with a few differences. Some softwood fiberboard properties tend to degrade faster in elevated humidity environments, while some cane fiberboard properties degrade faster in the hotter dry environments. As a result, it is premature to assume both materials will age at the same rates, and the preliminary aging models developed for cane fiberboard might not apply to softwood fiberboard. However, it is expected that both cane and softwood fiberboard assemblies will perform satisfactorily in conforming packages stored in a typical KAMS environment for up to 15 years. Aging and testing of softwood fiberboard will continue and additional data will be collected. Post-conditioning data have been measured on samples from a single softwood fiberboard assembly, and baseline data are also available from a limited number of vendor-provided samples. This provides minimal information on the possible sample-to-sample variation exhibited by softwood fiberboard. …

In our project, we proposed to continue analysis of our available soil samples and data, and to develop new studies to answer the following objectives: Objective 1) Broaden field based studies of ecosystem C and N compartments to enhance current understanding of C and N sequestration and dynamics. Objective 2) Improve our understanding of mechanism controlling C and N stabilization and dynamics. Objective 3) Investigate the interrelated role of soil temperature and organism type and activity as controlling mechanism in SOC dynamics and sequestration.

Recently, variational symplectic algorithms have been developed for the long-time simulation of charged particles in magnetic fields1-3. As a direct consequence of their derivation from a discrete variational principle, these algorithms have very good long-time energy conservation, as well as exactly preserving discrete momenta. We present stability results for these algorithms, focusing on understanding how explicit variational integrators can be designed for this type of system. It is found that for explicit algorithms an instability arises because the discrete symplectic structure does not become the continuous structure in the t → 0 limit. We examine how a generalized gauge transformation can be used to put the Lagrangian in the "antisymmetric discretization gauge," in which the discrete symplectic structure has the correct form, thus eliminating the numerical instability. Finally, it is noted that the variational guiding center algorithms are not electromagnetically gauge invariant. By designing a model discrete Lagrangian, we show that the algorithms are approximately gauge invariant as long as A and #30; are relatively smooth. A gauge invariant discrete Lagrangian is very important in a variational particle-in-cell algorithm where it ensures current continuity and preservation of Gauss's law4.

The Joint US-EC Short Course on Environmental Biotechnology is designed for several purposes. One of the central tenets is to bring together young scientists (at the late Ph.D. or early postdoctoral stages of their careers) in a forum that will set the groundwork for future overseas collaborative interactions. The course is also designed to give the scientists hands-on experience in modern, up-to-date biotechnological methods for the analysis of microbes and their activities pertinent to the remediation of pollutants in the environment. The 2011 course covered multiple theoretical and practical topics in environmental biotechnology. The practical part was centered around a full concise experiment to demonstrate the possibility for targeted remediation of contaminated soil. Experiments included chemical, microbiological, and molecular analyses of sediments and/or waters, contaminant bioavailability assessment, seeded bioremediation, gene probing, PCR amplification, microbial community analysis based on 16S rRNA gene diversity, and microarray analyses. Each of these topics is explained in detail. The practical part of the course was complemented with two lectures per day, given by distinguished scientists from the US and from Europe, covering a research area related to what the students are doing in the course.

To accurately define the risks associated with human exposure to relevant environmental doses of low LET ionizing radiation, it is necessary to completely understand the biological effects at very low doses (i.e., less than 0.1 Gy), including the lowest possible dose, that of a single electron track traversal. At such low doses, a range of studies have shown responses in biological systems which are not related to the direct interaction of radiation tracks with DNA. The role of these “non-targeted” responses in critical tissues is poorly understood and little is known regarding the underlying mechanisms. Although critical for dosimetry and risk assessment, the role of individual genetic susceptibility in radiation risk is not satisfactorily defined at present. The aim of the proposed grant is to critically evaluate radiation-induced genomic instability and bystander responses in key stem cell populations from haemopoietic tissue. Using stem cells from two mouse strains (CBA/H and C57BL/6J) known to differ in their susceptibility to radiation effects, we plan to carefully dissect the role of genetic predisposition on two non-targeted radiation responses in these models; the bystander effect and genomic instability, which we believe are closely related. We will specifically focus on the effects of low doses …

The Integrated Field Research Challenge (IFRC) at the Hanford Site 300 Area uranium (U) plume addresses multi-scale mass transfer processes in a complex subsurface biogeochemical setting where groundwater and riverwater interact. A series of forefront science questions on reactive mass transfer motivates research. These questions relate to the effect of spatial heterogeneities; the importance of scale; coupled interactions between biogeochemical, hydrologic, and mass transfer processes; and measurements and approaches needed to characterize and model a mass-transfer dominated biogeochemical system. The project was initiated in February 2007, with CY 2007, CY 2008, CY 2009, and CY 2010 progress summarized in preceding reports. A project peer review was held in March 2010, and the IFRC project acted upon all suggestions and recommendations made in consequence by reviewers and SBR/DOE. These responses have included the development of 'Modeling' and 'Well-Field Mitigation' plans that are now posted on the Hanford IFRC web-site, and modifications to the IFRC well-field completed in CY 2011. The site has 35 instrumented wells, and an extensive monitoring system. It includes a deep borehole for microbiologic and biogeochemical research that sampled the entire thickness of the unconfined 300 A aquifer. Significant, impactful progress has been made in CY 2011 including: …

A broadly applicable methodology has been developed to prepare new single site catalysts on silica supports. This methodology requires of three critical components: a rigid building block that will be the main structural and compositional component of the support matrix; a family of linking reagents that will be used to insert active metals into the matrix as well as cross link building blocks into a three dimensional matrix; and a clean coupling reaction that will connect building blocks and linking agents together in a controlled fashion. The final piece of conceptual strategy at the center of this methodology involves dosing the building block with known amounts of linking agents so that the targeted connectivity of a linking center to surrounding building blocks is obtained. Achieving targeted connectivities around catalytically active metals in these building block matrices is a critical element of the strategy by which single site catalysts are obtained. This methodology has been demonstrated with a model system involving only silicon and then with two metal-containing systems (titanium and vanadium). The effect that connectivity has on the reactivity of atomically dispersed titanium sites in silica building block matrices has been investigated in the selective oxidation of phenols to benezoquinones. …
