The 2009 Gordon Conference on Microbial Population Biology will cover a diverse range of cutting edge issues in the microbial sciences and beyond. Firmly founded in evolutionary biology and with a strongly integrative approach, past Conferences have covered a range of topics from the dynamics and genetics of adaptation to the evolution of mutation rate, community ecology, evolutionary genomics, altruism, and epidemiology. The 2009 Conference is no exception, and will include sessions on the evolution of infectious diseases, social evolution, the evolution of symbioses, experimental evolution, adaptive landscapes, community dynamics, and the evolution of protein structure and function. While genomic approaches continue to make inroads, broadening our knowledge and encompassing new questions, the conference will also emphasize the use of experimental approaches to test hypotheses decisively. As in the past, this Conference provides young scientists and graduate students opportunities to present their work in poster format and exchange ideas with leading investigators from a broad spectrum of disciplines. This meeting is never dull: some of the most significant and contentious issues in biology have been thrashed out here. The 2009 meeting will be no exception.

Carbon nanotubes were discovered in 1991 as a minority byproduct of fullerene synthesis. Remarkable progress has been made in the ensuing years, including the discovery of two basic types of nanotubes (single-wall and multi-wall), great strides in synthesis and purification, elucidation of many fundamental physical properties, and important steps towards practical applications. Both the underlying science and technological potential of SWNT can profitably be studied at the scale of individual tubes and on macroscopic assemblies such as fibers. Experiments on single tubes directly reveal many of the predicted quantum confinement and mechanical properties. Semiconductor nanowires have many features in common with nanotubes, and many of the same fundamental and practical issues are in play – quantum confinement and its effect on properties; possible device structures and circuit architectures; thermal management; optimal synthesis, defect morphology and control, etc. In 2000 we began a small effort in this direction, conducted entirely by undergraduates with minimal consumables support from this grant. With DOE-BES approval, this grew into a project in parallel with the carbon nanotube work, in which we studied of inorganic semiconductor nanowire growth, characterization and novel strategies for electronic and electromechanical device fabrication. From the beginnings of research on carbon nanotubes, …

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Justice (DOJ) estimates that the United States has about a million gang members. While state and local agencies have primary responsibility for combating gang crime, the federal government has key roles to enforce laws and help fund programs to provide alternatives to gang membership for at-risk youth. GAO was asked to examine federal efforts to combat gang crime. This report addresses (1) the roles of DOJ and the Department of Homeland Security (DHS) in combating gang crime and the extent to which DOJ and DHS agencies coordinate their efforts with each other and state and local agencies; (2) the extent to which DOJ and DHS measure their gang enforcement efforts; and (3) how federal grant funding is used to administer or support activities to reduce gang-related crime. GAO reviewed federal agencies' plans, resources, and measures and interviewed federal, state, and local officials in 15 localities with federally led anti-gang task forces representing varying population sizes and locations."

A letter report issued by the Government Accountability Office with an abstract that begins "Since 2001, the National Archives and Records Administration (NARA) has been developing an Electronic Records Archive (ERA) to preserve and provide access to massive volumes of electronic records independent of their original hardware and software. The ERA system is to include a base system for federal records and a separate system for presidential records, known as the Executive Office of the President (EOP) system. The 2009 Omnibus Appropriations Act requires NARA to submit an expenditure plan for ERA to congressional appropriation committees. GAO's objectives were to (1) determine whether NARA's fiscal year 2009 plan meets the legislative conditions set forth in the 2009 Omnibus Appropriations Act, (2) provide an update on NARA's progress in implementing recommendations made in GAO's review of NARA's 2008 expenditure plan, and (3) provide any other observations about the expenditure plan and the ERA acquisition. To do this, GAO reviewed the expenditure plan, interviewed NARA officials, and reviewed program data and documentation."

A letter report issued by the Government Accountability Office with an abstract that begins "The federal-aid highway program provides about $33 billion a year to states for highway projects. The federal government provides funding for and oversees this program, while states largely choose and manage the projects. As requested, GAO reviewed the Federal Highway Administration's (FHWA) implementation of several requirements in the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU): (1) oversight of states using a risk management approach; (2) efforts to develop minimum standards for estimating project costs, and periodically evaluate states' cost estimating practices; and (3) reviews of states' financial management systems. GAO also reviewed FHWA's policy on presenting an estimate of financing costs in financial plans for major projects (i.e., projects estimated to cost over $500 million). GAO reviewed FHWA plans, risk assessments, reviews, and other documents; visited five FHWA field offices and reviewed financial management reviews in an additional five field offices; and interviewed FHWA officials."

Power extraction using a dielectric-loaded (DL) waveguide is a way to generate high-power radio frequency (RF) waves for future particle accelerators, especially for two-beam-acceleration. In a two-beam-acceleration scheme, a low-energy, high-current particle beam is passed through a deceleration section of waveguide (decelerator), where the power from the beam is partially transferred to trailing electromagnetic waves (wakefields); then with a properly designed RF output coupler, the power generated in the decelerator is extracted to an output waveguide, where finally the power can be transmitted and used to accelerate another usually high-energy low-current beam. The decelerator, together with the RF output coupler, is called a power extractor. At Argonne Wakefield Accelerator (AWA), we designed a 7.8GHz power extractor with a circular DL waveguide and tested it with single electron bunches and bunch trains. The output RF frequency (7.8GHz) is the sixth harmonic of the operational frequency (1.3GHz) of the electron gun and the linac at AWA. In single bunch excitation, a 1.7ns RF pulse with 30MW of power was generated by a single 66nC electron bunch passing through the decelerator. In subsequent experiments, by employing different splitting-recombining optics for the photoinjector laser, electron bunch trains were generated and thus longer RF pulses …

Correspondence issued by the Government Accountability Office with an abstract that begins "Girls' delinquency has attracted the attention of federal, state, and local policymakers for more than a decade as girls have increasingly become involved in the juvenile justice system. For example, from 1995 through 2005, delinquency caseloads for girls in juvenile justice courts nationwide increased 15 percent while boys' caseloads decreased by 12 percent. Also, from 1995 through 2005, the number of girls' cases nationwide involving detention increased 49 percent compared to a 7 percent increase for boys. More recently, in 2007, 29 percent of juvenile arrests--about 641,000 arrests--involved girls, who accounted for 17 percent of juvenile violent crime arrests and 35 percent of juvenile property crime arrests. Further, in a 2007 survey of states conducted by the Federal Advisory Committee on Juvenile Justice, 22 states listed girls' delinquency as an issue affecting their states' juvenile justice systems. State justice officials responding to the survey noted that juvenile female offenses have increased sharply and also noted that juvenile female offenders generally had more serious and wide-ranging service needs than juvenile male offenders, including treatment for substance abuse and mental health conditions. As programs have been developed at the state …

A letter report issued by the Government Accountability Office with an abstract that begins "Recent losses in the stock market and poor economic conditions underscore that many U.S. workers are at risk of not having an adequate income in retirement from pension plans. The dramatic decline in the stock market has diminished pension savings and reportedly led to low levels in older Americans' confidence in their ability to retire. Even before the current economic recession, research indicated that pension benefits are likely to be inadequate for many Americans. This report addresses the following questions: (1) What are key risks faced by U.S. workers in accumulating and preserving pension benefits? (2) What approaches are used in other countries that could address these risks and what trade-offs do they present? (3) What approaches do key proposals for alternative plan designs in the U.S. suggest to mitigate risks faced by workers and what trade-offs do they entail? To complete this work, we reviewed research on defined benefit and defined contribution plans, and interviewed pension consulting firms, industry experts, academics, and other relevant organizations in the U.S. and abroad. In addition, we used a microsimulation model to assess the impact of certain strategies to …

Correspondence issued by the Government Accountability Office with an abstract that begins "This report formally transmits the briefing in response to section 247d-6c of title 42 of the United States Code. The statute required the Comptroller General to examine the Department of Health and Human Services' (HHS) support for the development and procurement of and authority for the emergency use of medical countermeasures to address chemical, biological, radiological, and nuclear threats to public health, and provide the results to the congressional committees by July 21, 2009."

Finally, this report discusses whether there must be exceptions to a requirement to purchase health insurance based on First Amendment freedom of religion.

In fiscal years 2007 and 2008, the Hanford Site Groundwater Remediation Project, formerly managed by Fluor Hanford, Inc., requested the Pacific Northwest National Laboratory (PNNL) to support the development and initial implementation of a strategy to establish and maintain, under configuration control, a set of Hanford-specific flow and transport parameter estimates that can be used to support Hanford Site assessments. This document provides a summary of those efforts, culminating in a set of best-estimate Hanford-specific parameters for use in place of the default parameters used in the RESRAD code. The RESRAD code is a computer model designed to estimate radiation doses and risks from RESidual RADioactive materials. The long-term goals of the PNNL work are to improve the consistency, defensibility, and traceability of parameters and their ranges of variability, and to ensure a sound basis for assigning parameters for flow and transport models in the code. The strategy was to start by identifying the existing parameter data sets most recently used in site assessments, documenting these parameter data sets and the raw data sets on which they were based, and using the existing parameter sets to define best-estimate parameters for use in the RESRAD code. The Hanford-specific assessment parameters compiled …
