A letter report issued by the Government Accountability Office with an abstract that begins "The Homeless Emergency Assistance and Rapid Transition to Housing Act of 2009 (HEARTH Act) directed GAO to study the appropriate administrative costs of the U.S. Department of Housing and Urban Development (HUD) Emergency Shelter Grants Program (ESG)--a widely used, formula-based program that supports services to persons experiencing homelessness. This report discusses (1) for selected recipients, the types of administrative activities performed and administrative costs incurred under the ESG program, and the extent to which grant proceeds cover these administrative costs; (2) how the ESG program's allowance for administrative costs compares with administrative cost allowances for selected other targeted federal homeless grant programs, plus selected other HUD formula-based grant programs; and (3) how the nature or amount of administrative costs might be different under changes Congress made to the ESG program in the HEARTH Act that expand the types of activities that may be funded. To address these issues, GAO reviewed relevant policies and documents, interviewed officials of HUD and other agencies, made site visits in four states, reviewed HUD and other available standards on eligible administrative costs for federal grants, and reviewed cost allowances for homeless …

A letter report issued by the Government Accountability Office with an abstract that begins "To enhance aviation security, the Transportation Security Administration (TSA) began initial testing in October 2003 of its Screening of Passengers by Observation Techniques (SPOT) program. Behavior Detection Officers (BDO) carry out SPOT's mission to identify persons who pose a risk to aviation security by focusing on behavioral and appearance indicators. GAO was asked to review the SPOT program. GAO analyzed (1) the extent to which TSA validated the SPOT program before deployment, (2) implementation challenges, and (3) the extent to which TSA measures SPOT's effect on aviation security. GAO analyzed TSA documents, such as strategic plans and operating procedures; interviewed agency personnel and subject matter experts; and visited 15 SPOT airports, among other things. Although the results from these visits are not generalizable, they provided insights into SPOT operations."

Lignocellulosic biomass is a promising feedstock for producing renewable chemicals and transportation fuels as petroleum substitutes. Fermentation of the cellulose in biomass in an SSF process requires that the properties of the microbial biocatalyst match the fungal cellulase activity optima for cost-effective production of products. Fermentation of the pentose sugars derived from hemicellulose in biomass is an additional asset of an ideal biocatalyst. The microbial biocatalyst used by the industry, yeast, lacks the ability to ferment pentose sugars. The optimum temperature for growth and fermentation of yeast is about 35°C. The optimum temperature for commercially available cellulase enzymes for depolymerization of cellulose in biomass to glucose for fermentation is 50-55 °C. Because of the mismatch in the temperature optima for the enzyme and yeast, SSF of cellulose to ethanol (cellulosic ethanol) with yeast is conducted at a temperature that is close to the optimum for yeast. We have shown that by increasing the temperature of SSF to 50-55 °C using thermotolerant B. coagulans, the amount of cellulase required for SSF of cellulose to products can be reduced by 3-4 –fold compared to yeast-based SSF at 35°C with a significant cost savings due to lower enzyme loading. Thermotolerant Bacillus coagulans strains …

This report discusses the Securities and Exchange Commission (SEC) role that oversees matters related to the content of proxy materials.

Trafficking in persons (TIP) for the purposes of exploitation is both an international and a domestic crime that involves violations of labor, public health, and human rights standards. This report focuses on human trafficking both internationally and within the United States. The report begins with an overview of human trafficking including a discussion of the definition of human trafficking, the scope of the problem globally, and an examination of the victims. It follows with an analysis of global anti-trafficking efforts by the United States and the international community. The report then focuses on trafficking into and within the United States, examining relief for trafficking victims in the United States and discussing U.S. law enforcement efforts to combat domestic trafficking. The report concludes with an overview of anti-trafficking legislation and an analysis of policy issues related to human trafficking.

This report discusses the current political conditions of Rwanda, including a brief historical overview. The report also includes information about the poor human rights conditions in Rwanda and U.S. Rwanda relations.

This report briefly discusses the context in which federal budget process changes are made and identifies selected reform proposals by major category. The identification of reform proposals in this report is not intended to be comprehensive.

The first real-time detection of surface dust inside a tokamak was made using an electrostatic dust detector. A fine grid of interlocking circuit traces was installed in the NSTX vessel and biased to 50 v. Impinging dust particles created a temporary short circuit and the resulting current pulse was recorded by counting electronics. The techniques used to increase the detector sensitivity by a factor of x10,000 to match NSTX dust levels while suppressing electrical pickup are presented. The results were validated by comparison to lab measurements, by the null signal from a covered detector that was only sensitive to pickup, and by the dramatic increase in signal when Li particles were introduced for wall conditioning purposes.

Scientific applications and experimental facilities generate massive data sets that need to be transferred to remote collaborating sites for sharing, processing, and long term storage. In order to support increasingly data-intensive science, next generation research networks have been deployed to provide high-speed on-demand data access between collaborating institutions. In this paper, we present a practical model for online data scheduling in which data movement operations are scheduled in advance for end-to-end high performance transfers. In our model, data scheduler interacts with reservation managers and data transfer nodes in order to reserve available bandwidth to guarantee completion of jobs that are accepted and confirmed to satisfy preferred time constraint given by the user. Our methodology improves current systems by allowing researchers and higher level meta-schedulers to use data placement as a service where theycan plan ahead and reserve the scheduler time in advance for their data movement operations. We have implemented our algorithm and examined possible techniques for incorporation into current reservation frameworks. Performance measurements confirm that the proposed algorithm is efficient and scalable.
