Most civilian federal employees who were hired before 1984 are covered by the Civil Service Retirement System, and contribute 7.0% of their pay to a retirement fund. Federal employees hired in 1984 or later are covered by the Federal Employees' Retirement System and contribute 0.8% of their pay to a retirement fund. Both require participants to contribute toward the cost of their pensions through a payroll tax. The taxable wage base is $110,100 in 2012. This report discusses both retirement funds.

The United States and Russia signed a new strategic arms reduction treaty - known as New START - on April 8, 2010. This treaty is designed to replace the 1991 Strategic Arms Reductions Treaty (START), which expired, after 15 years of implementation, on December 5, 2009. This report provides an overview of New START, including a comparison to the original START Treaty, the belief of the Obama Administration and outside analysts that New START will enhance U.S. national security, and the criticisms of those who say that New START (and, indeed, the entire issue of U.S.-Russian arms control) is a distraction from more important items on the nonproliferation agenda.

This report provides an overview of U.S. policy toward Latin America and the Caribbean, including the Obama Administration's priorities for U.S. policy and a brief comparison of policies under the Obama and Bush Administrations. It then examines congressional interest in Latin America, first providing an overview, and then looking at selected countries and regional issues and identifying key policy issues facing Congress in 2012. The final section of the report analyzes several upcoming events in the region in 2012 that could have an impact on developments in several countries or on U.S. relations with the region.

Background of the Fire Grants Authorization Act of 2011, including its purpose and uses of funding resulting from the act.

Japan and the United States are the two largest economic powers. Together they account for over 30% of world domestic product, for a significant portion of international trade in goods and services, and for a major portion of international investment. This economic clout makes the United States and Japan potentially powerful actors in the world economy. Economic conditions in the United States and Japan have a significant impact on the rest of the world. Furthermore, the U.S.-Japan bilateral economic relationship can influence economic conditions in other countries. More generally, other issues regarding U.S.-Japan economic relations may emerge on the agenda of the 112th Congress. U.S. and Japanese leaders have several options on how to manage their relationship, including stronger reliance on the World Trade Organization; special bilateral negotiating frameworks and agreements; or a free trade agreement.

This report discusses the firefighting activities that are traditionally the responsibility of states and local communities. The report also talks about the funding for firefighters, which is provided mostly by state and local governments. However, during the 106th Congress, many in the fire community asserted that local fire departments require and deserve greater support from the federal government.

During the Senate debate on the new U.S.-Russian Strategic Arms Reduction Treaty (New START) in 2010, many Senators raised questions about Russian nonstrategic nuclear weapons and noted their absence from the treaty limits. The United States and Russia have not included limits on these weapons in past arms control agreements. Nevertheless, Congress may press the Administration to seek solutions to the potential risks presented by these weapons in the future. This report looks at issues for Congress to consider regarding US weapons policy in light of the START agreement.

In response to concerns over the adequacy of firefighter staffing, the Staffing for Adequate Fire and Emergency Response Act—popularly called the “SAFER Act”—was enacted by the 108th Congress as Section 1057 of the FY2004 National Defense Authorization Act (P.L. 108-136). The SAFER Act authorizes grants to career, volunteer, and combination local fire departments for the purpose of increasing the number of firefighters to help communities meet industry-minimum standards and attain 24-hour staffing to provide adequate protection from fire and fire-related hazards. Also authorized are grants to volunteer fire departments for recruitment and retention of volunteers. With the economic turndown adversely affecting budgets of local governments, concerns have arisen that modifications to the SAFER statute may be necessary to enable fire departments to more effectively participate in the program.

President Obama's FY2013 budget submission was released on February 13, 2012. This report provides a graphical overview of historical trends in discretionary budget authority (BA) from FY1976 through FY2011, enacted levels for FY2012 spending, and the levels consistent with the President's proposals for FY2013 through FY2017. Spending caps and budget enforcement mechanisms established in the Budget Control Act (BCA) of 2011 will probably strongly affect the FY2013 budget cycle. This report may provide a starting point for discussions about spending trends and federal priorities, but it does not attempt to explain spending patterns in each policy area.

This paper summarizes the activities of the National Atmospheric Release Advisory Center (NARAC) during the Fukushima Dai-ichi nuclear power plant crisis. NARAC provided a wide range of products and analyses as part of its support including: (1) Daily Japanese weather forecasts and hypothetical release (generic source term) dispersion predictions to provide situational awareness and inform planning for U.S. measurement data collection and field operations; (2) Estimates of potential dose in Japan for hypothetical scenarios developed by the Nuclear Regulatory Commission (NRC) to inform federal government considerations of possible actions that might be needed to protect U.S. citizens in Japan; (3) Estimates of possible plume arrival times and dose for U.S. locations; and (4) Plume model refinement and source estimation based on meteorological analyses and available field data. The Department of Energy/National Nuclear Security Administration (DOE/NNSA) deployed personnel to Japan and stood up 'home team' assets across the DOE complex to aid in assessing the consequences of the releases from the Fukushima Dai-ichi Nuclear Power Plant. The DOE Nuclear Incident Team (NIT) coordinated response activities, while DOE personnel provided predictive modeling, air and ground monitoring, sample collection, laboratory analysis, and data assessment and interpretation. DOE deployed the Aerial Measuring System (AMS), …

Air-cooled stack technology offers the potential for a simpler system architecture (versus liquid-cooled) for applications below 4 kilowatts. The combined cooling and cathode air allows for a reduction in part count and hence a lower cost solution. However, efficient heat rejection challenges escalate as power and ambient temperature increase. For applications in ambient temperatures below freezing, the air-cooled approach has additional challenges associated with not overcooling the fuel cell stack. The focus of this project was freeze tolerance while maintaining all other stack and system requirements. Through this project, Plug Power advanced the state of the art in technology for air-cooled PEM fuel cell stacks and related GenDrive material handling application fuel cell systems. This was accomplished through a collaborative work plan to improve freeze tolerance and mitigate freeze-thaw effect failure modes within innovative material handling equipment fuel cell systems designed for use in freezer forklift applications. Freeze tolerance remains an area where additional research and understanding can help fuel cells to become commercially viable. This project evaluated both stack level and system level solutions to improve fuel cell stack freeze tolerance. At this time, the most cost effective solutions are at the system level. The freeze mitigation strategies developed …

SuperB is a high luminosity e{sup +}e{sup -} collider that will be able to indirectly probe new physics at energy scales far beyond the reach of any man made accelerator planned or in existence. Just as detailed understanding of the Standard Model of particle physics was developed from stringent constraints imposed by flavour changing processes between quarks, the detailed structure of any new physics is severely constrained by flavour processes. In order to elucidate this structure it is necessary to perform a number of complementary studies of a set of golden channels. With these measurements in hand, the pattern of deviations from the Standard Model behavior can be used as a test of the structure of new physics. If new physics is found at the LHC, then the many golden measurements from SuperB will help decode the subtle nature of the new physics. However if no new particles are found at the LHC, SuperB will be able to search for new physics at energy scales up to 10-100 TeV. In either scenario, flavour physics measurements that can be made at SuperB play a pivotal role in understanding the nature of physics beyond the Standard Model. Examples for using the interplay …

We use the first 25% of the DEEP2 Galaxy Redshift Survey spectroscopic data to identify groups and clusters of galaxies in redshift space. The data set contains 8370 galaxies with confirmed redshifts in the range 0.7 {<=} z {<=} 1.4, over one square degree on the sky. Groups are identified using an algorithm (the Voronoi-Delaunay Method) that has been shown to accurately reproduce the statistics of groups in simulated DEEP2-like samples. We optimize this algorithm for the DEEP2 survey by applying it to realistic mock galaxy catalogs and assessing the results using a stringent set of criteria for measuring group-finding success, which we develop and describe in detail here. We find in particular that the group-finder can successfully identify {approx}78% of real groups and that {approx}79% of the galaxies that are true members of groups can be identified as such. Conversely, we estimate that {approx}55% of the groups we find can be definitively identified with real groups and that {approx}46% of the galaxies we place into groups are interloper field galaxies. Most importantly, we find that it is possible to measure the distribution of groups in redshift and velocity dispersion, n({sigma}, z), to an accuracy limited by cosmic variance, for …
