Over the past 25 years, defined contribution (DC) plans - including 401(k) plans - have become the most prevalent form of employer-sponsored retirement plan in the United States. This report describes seven major policy issues with respect to defined contribution plans: 1) access to employer-sponsored retirement plans; 2) participation in employer-sponsored plans; 3) contribution rates; 4) investment choices; 5) fee disclosure; 6) leakage from retirement savings; and 7) converting retirement savings into income.

The U.S. Department of Energy’s (DOE) commitment to assuring the health and safety of its workers includes the conduct of epidemiologic surveillance activities that provide an early warning system for health problems among workers. The Illness and Injury Surveillance Program monitors illnesses and health conditions that result in an absence of workdays, occupational injuries and illnesses, and disabilities and deaths among current workers.

Epigenetics refers to the study of heritable changes in genome function that occur without a change in primary DNA sequence. The 2009 Gordon Conference in Epigenetics will feature discussion of various epigenetic phenomena, emerging understanding of their underlying mechanisms, and the growing appreciation that human, animal, and plant health all depend on proper epigenetic control. Special emphasis will be placed on genome-environment interactions particularly as they relate to human disease. Towards improving knowledge of molecular mechanisms, the conference will feature international leaders studying the roles of higher order chromatin structure, noncoding RNA, repeat elements, nuclear organization, and morphogenic evolution. Traditional and new model organisms are selected from plants, fungi, and metazoans.

The National Compact Stellarator Experiment (NCSX) was a collaborative effort between ORNL and PPPL. PPPL provided the assembly techniques with guidance from ORNL to meet design criteria. The individual vacuum vessel segments, modular coils, trim coils, and toroidal field coils components were delivered to the Field Period Assembly (FPA) crew who then would complete the component assemblies and then assemble the final three field period assemblies, each consisting of two sets of three modular coils assembled over a 120o vacuum vessel segment with the trim coils and toroidal field coils providing the outer layer. The requirements for positioning the modular coils were found to be most demanding. The assembly tolerances required for accurate positioning of the field coil windings in order to generate sufficiently accurate magnetic fields strained state of the art techniques in metrology and alignment and required constant monitoring of assembly steps with laser trackers, measurement arms, and photogrammetry. The FPA activities were being performed concurrently while engineering challenges were being resolved. For example, it was determined that high friction electrically isolated shims were needed between the modular coil interface joints and low distortion welding was required in the nose region of those joints. This took months of …

This report discusses the current political state of Afghanistan, focusing particularly on the influence of the Taliban and other militant groups and on the leadership of Afghan President Hamid Karzai. This report also discusses the U.S.-Afghanistan relationship and U.S. efforts under the Obama Administration to provide military, reconstructive, and stabilization aid.

The U.S. program of assistance to Afghanistan is intended to stabilize and strengthen the Afghan economic, social, political, and security environment so as to blunt popular support for extremist forces in the region. Since 2001, nearly $38 billion has been appropriated toward this effort. This report provides a "big picture" overview of the U.S. aid program and congressional action. It describes what various aid agencies report they are doing in Afghanistan. It does not address the effectiveness of their programs.

A letter report issued by the Government Accountability Office with an abstract that begins "Financial investigations are used to combat money laundering and terrorism financing, crimes that can destabilize national economies and threaten global security. The Financial Crimes Enforcement Network (FinCEN) within the Department of the Treasury supports law enforcement agencies (LEAs) in their efforts to investigate financial crimes by providing them with services and products, such as access to financial data, analysis, and case support. As requested, GAO examined the extent to which the law enforcement community finds FinCEN's support useful in its efforts to investigate and prosecute financial crimes. GAO analyzed statutes governing FinCEN's mission and documentation describing the support it provides to LEAs, such as annual reports. Using FinCEN data, GAO selected a sample of 29 LEAs, including primary users of FinCEN's services and products, and obtained their opinions through a survey and interviews. While the results of the survey and interviews are not generalizable, they provide insights about the usefulness of FinCEN's support."

In Year 1 of this project, items 1.1 and 1.2 were addressed, as well as item 2.2. The baseline parallel computational simulation tool has been refined significantly over the timeline of this project for the purpose of atmospheric dispersion and transport problems; some of these refinements are documented in Chapter 3. The addition of a concentration transport capability (item 1.2) was completed, along with validation and usage in a highly complex urban environment. Multigrid capability (item 2.2) was a primary focus of Year 1 as well, regardless of the fact that it was scheduled for Year 2. It was determined by the authors that due to the very large nature of the meshes required for atmospheric simulations at mesoscale, multigrid was a key enabling technology for the rest of the project to be successful. Therefore, it was addressed early according to the schedule laid out in the original proposal. The technology behind the multigrid capability is discussed in detail in Chapter 5. Also in Year 1, the issue of ground topography specification is addressed. For simulations of pollutant transport in a given region, a key prerequisite is the specification of the detailed ground topography. The local topography must be placed …

Individual raw data streams from instrumentation at the Atmospheric Radiation Measurement (ARM) Program Climate Research Facility (ACRF) fixed and mobile sites are collected and sent to the Data Management Facility (DMF) at Pacific Northwest National Laboratory (PNNL) for processing in near-real time. Raw and processed data are then sent approximately daily to the ACRF Archive, where they are made available to users. For each instrument, we calculate the ratio of the actual number of data records received daily at the archive to the expected number of data records. The results are tabulated by (1) individual data stream, site, and month for the current year and (2) site and fiscal year (FY) dating back to 1998. The U.S. Department of Energy (DOE) requires national user facilities to report time-based operating data. The requirements concern the actual hours of operation (ACTUAL); the estimated maximum operation or uptime goal (OPSMAX), which accounts for planned downtime; and the VARIANCE [1 - (ACTUAL/OPSMAX)], which accounts for unplanned downtime. The OPSMAX time for the third quarter of FY 2009 for the Southern Great Plains (SGP) site is 2,074.80 hours (0.95 x 2,184 hours this quarter); for the North Slope Alaska (NSA) locale it is 1,965.60 hours …

A letter report issued by the Government Accountability Office with an abstract that begins "By deploying armed air marshals onboard selected flights, the Federal Air Marshal Service (FAMS), a component of the Transportation Security Administration (TSA), plays a key role in helping to protect approximately 29,000 domestic and international flights operated daily by U.S. air carriers. GAO was asked to examine (1) FAMS's operational approach or "concept of operations" for covering flights, (2) to what extent this operational approach has been independently evaluated, and (3) the processes and initiatives FAMS established to address workforce-related issues. GAO analyzed documented policies and procedures regarding FAMS's operational approach and a July 2006 classified report based on an independent evaluation of that approach. Also, GAO analyzed employee working group reports and other documentation of FAMS's processes and initiatives for addressing workforce-related issues, and interviewed the FAMS Director, other senior officials, and 67 air marshals (selected to reflect a range in levels of experience). This report is the public version of a restricted report (GAO-09-53SU) issued in December 2008."

The authors present updated measurements of the branching fractions for B{sup 0} meson decays to {eta}K{sup 0}, {eta}{eta}, {eta}{phi}, {eta}{omega}, {eta}{prime}K{sup 0}, {eta}{prime}{eta}{prime}, {eta}{prime}, {phi}, and {eta}{prime}{omega} and branching fractions and CP-violating charge asymmetries for B{sup +} decays to {eta}{pi}{sup +}, {eta}K{sup +}, {eta}{prime}{pi}{sup +}, and {eta}{prime} K{sup +}. The data represent the full dataset of 467 x 10{sup 6} B{bar B} pairs collected with the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} collider at the SLAC National Accelerator Laboratory. Besides large signals for the four charged B decays modes and for B{sup 0} {yields} {eta}{prime}K{sup 0}, they find evidence for three B{sup 0} decays modes at greater than 3.0{sigma} significance. They find {Beta}(B{sup 0} {yields} {eta}K{sup 0}) = (1.15{sub -0.38}{sup +0.43} {+-} 0.09) x 10{sup -6}, {Beta}(B{sup 0} {yields} {eta}{omega}) = (0.94{sub -0.30}{sup +0.35} {+-} 0.09) x 10{sup -6}, and {Beta}(B{sup 0} {yields} {eta}{prime}{omega}) = (1.01{sub -0.38}{sup +0.46} {+-} 0.09) x 10{sup -6}, where the first (second) uncertainty is statistical (systematic). For the B{sup +} {yields} {eta}K{sup +} decay mode, they measure the charge asymmetry {Alpha}{sub ch} (B{sup +} {yields} {eta}K{sup +}) = -0.36 {+-} 0.11 {+-} 0.03.

We report on the first optical measurements of the rare-earth tri-telluride charge-density-wave systems. Our data, collected over an extremely broad spectral range, allow us to observe both the Drude component and the single-particle peak, ascribed to the contributions due to the free charge carriers and to the charge-density-wave gap excitation, respectively. The data analysis displays a diminishing impact of the charge-density-wave condensate on the electronic properties with decreasing lattice constant across the rare-earth series. We propose a possible mechanism describing this behavior and we suggest the presence of a one-dimensional character in these two-dimensional compounds. We also envisage that interactions and umklapp processes might play a relevant role in the formation of the charge-density-wave state in these compounds.

Clouds represent a critical component of the Earth’s atmospheric energy balance as a result of their interactions with solar and terrestrial radiation and a redistribution of heat through convective processes and latent heating. Despite their importance, clouds and the processes that control their development, evolution and lifecycle remain poorly understood. Consequently, the simulation of clouds and their associated feedbacks is a primary source of inter-model differences in equilibrium climate sensitivity. An important step in improving the representation of cloud process simulations is an improved high-resolution observational data set of the cloud systems including their time evolution. The first order quantity needed to understand the important role of clouds is the height of cloud occurrence and how it changes as a function of time. To this end, the Atmospheric Radiation Measurement (ARM) Climate Research Facilities (ACRF) suite of instrumentation has been developed to make the observations required to improve the representation of cloud systems in atmospheric models.

A letter report issued by the Government Accountability Office with an abstract that begins "The Deepwater Program includes efforts to build or modernize ships and aircraft and to procure other capabilities. In 2002, the Coast Guard contracted with Integrated Coast Guard Systems (ICGS) to manage the acquisition as systems integrator. After a series of project failures, the Coast Guard announced in April 2007 that it would take over the lead role, with future work on individual assets bid competitively, and a program baseline of $24.2 billion was set. In June 2008, GAO reported on the Coast Guard's progress and made several recommendations, which the Coast Guard and the Department of Homeland Security (DHS) have addressed. In response to a Senate report accompanying the DHS Appropriations Bill, 2009, GAO addressed (1) efforts to manage Deepwater, (2) changes in cost and schedule of the assets, and (3) efforts to build an acquisition workforce. GAO reviewed Coast Guard and DHS documents and interviewed officials."

Final Report for grant DE-FG02-06ER54888, "Simulation of Beam-Electron Cloud Interactions in Circular Accelerators Using Plasma Models" Viktor K. Decyk, University of California, Los Angeles Los Angeles, CA 90095-1547 The primary goal of this collaborative proposal was to modify the code QuickPIC and apply it to study the long-time stability of beam propagation in low density electron clouds present in circular accelerators. The UCLA contribution to this collaborative proposal was in supporting the development of the pipelining scheme for the QuickPIC code, which extended the parallel scaling of this code by two orders of magnitude. The USC work was as described here the PhD research for Ms. Bing Feng, lead author in reference 2 below, who performed the research at USC under the guidance of the PI Tom Katsouleas and the collaboration of Dr. Decyk The QuickPIC code [1] is a multi-scale Particle-in-Cell (PIC) code. The outer 3D code contains a beam which propagates through a long region of plasma and evolves slowly. The plasma response to this beam is modeled by slices of a 2D plasma code. This plasma response then is fed back to the beam code, and the process repeats. The pipelining is based on the observation that …

Testimony issued by the Government Accountability Office with an abstract that begins "A terrorist's use of a radiological dispersal device (RDD) or improvised nuclear device (IND) to release radioactive materials into the environment could have devastating consequences. The timely cleanup of contaminated areas, however, could speed the restoration of normal operations, thus reducing the adverse consequences from an incident. This testimony examines (1) the extent to which federal agencies are planning to fulfill their responsibilities to assist cities and their states in cleaning up areas contaminated with radioactive materials from RDD and IND incidents; (2) what is known about the federal government's capability to effectively cleanup areas contaminated with radioactive materials from RDD and IND incidents, and (3) suggestions from government emergency management officials on ways to improve federal preparedness to provide assistance to recover from RDD and IND incidents. We also discuss recovery activities in the United Kingdom. This testimony is based on our ongoing review of recovery preparedness issues for which we examined applicable federal laws and guidance; interviewed officials from the Department of Homeland Security (DHS), Federal Emergency Management Agency (FEMA), Department of Energy (DOE), and Environmental Protection Agency (EPA); and surveyed emergency management officials from 13 …
