This report focuses on two main National Security Agency (NSA) collection activities approved by the Foreign Intelligence Surveillance Court (FISC) established under the Foreign Intelligence Surveillance Act (FISA) of 1978. The first is the bulk collection of telephony metadata for domestic and international telephone calls. The second involves the interception of Internet-based communications and is targeted at foreigners who are not within the United States, but may also inadvertently acquire the communications of U.S. persons.

A letter report issued by the Government Accountability Office with an abstract that begins "In fiscal year 2013, the Missile Defense Agency (MDA) made mixed progress in achieving its acquisition goals to develop, test, and produce elements of the Ballistic Missile Defense System (BMDS). For the first time, MDA conducted an operational flight test that involved warfighters from several combatant commands using multiple BMDS elements simultaneously. The agency also successfully conducted several developmental flight tests that demonstrated key capabilities and modifications made to resolve prior production issues. However, the Aegis BMD and Ground-based Midcourse Defense (GMD) continued to experience testing and development challenges."

This report provides an overview of federal statutes that provide civil remedies for contractor fraud, as well as issues stemming from judicial interpretation of these statutes.

This report looks at the purpose and background of Community Services Block Grants (CSBG), which provide federal funds to states, territories, and tribes for distribution to local agencies to support a wide range of community-based activities to reduce poverty. It includes program data, funding activity for fiscal years 2013 and 2014, and proposals for FY2015.

This report discusses the Patient Protection and Affordable Care Act (ACA, P.L. 111-148, as amended) that contains a number of provisions that may affect the individual health insurance market.

This report provides background information and issues for Congress on the sustainment and modernization of the Coast Guard's polar icebreaker fleet, which performs a variety of missions supporting U.S. interests in polar regions. The report is written in response to the Coast Guard's budget request for a new polar ice breaker (none are currently in operation).

This report discusses the Energy and Water Development appropriations bill that provides funding for civil works projects of the Army Corps of Engineers (Corps), for the Department of the Interior's Bureau of Reclamation (Reclamation), the Department of Energy (DOE), and several independent agencies.

This report provides background information on the historical circumstances that led to the adoption of the Voting Rights Act (VRA), a summary of its major provisions, and a brief discussion of the U.S. Supreme Court decision and related legislation in the 113th Congress.

This report provides an overview of U.S.-Mexico trade and economic trends, the Mexican economy, the effects of the North American Free Trade Agreement (NAFTA), and major trade issues between the United States and Mexico.

This report discusses the Millennium Challenge Corporation (MCC), which provides economic assistance through a competitive selection process to developing nations that are pursuing political and economic reforms in three areas: ruling justly, investing in people, and fostering economic freedom. It also discusses several concerns related to MCC implementation, including the level of funding to support MCC programs.

This report provides an overview of the federal health center program including its statutory authority, program requirements, and appropriation levels. The report then describes health centers in general, where they are located, their patient population, and some outcomes associated with health center use. It also describes some federal programs available to assist health center operations as well as issues for Congress.

This report discusses how the Federal Reserve (Fed) handles monetary policy, including background information about the execution of monetary policy, the recent and current stance of monetary policy, and current legislation and Congressional oversight that would affect the Fed's practices.

This report is categorized into five categories: (I) Introduction, (II) What is Public Transportation, (III) Funding the Federal Transportation Program, (IV) How are Federal Dollars Spent?, and (V) Program Structure.

This report provides background information and issues for Congress on the sustainment and modernization of the Coast Guard’s polar icebreaker fleet, which performs a variety of missions supporting U.S. interests in polar regions. The Coast Guard’s proposed FY2015 budget requests $6 million to continue initial acquisition activities for a new polar icebreaker. The issue for Congress is whether to approve, reject, or modify Coast Guard plans for sustaining and modernizing its polar icebreaking fleet. Congressional decisions on this issue could affect Coast Guard funding requirements, the Coast Guard’s ability to perform its polar missions, and the U.S. shipbuilding industrial base.

This report describes results of experiments that were conducted in an unoccupied 1600 square foot house--the Manufactured Housing (MH Lab) at the Florida Solar Energy Center (FSEC)--to evaluate the delivered performance as well as the relative performance of a SEER 21 variable capacity heat pump versus a SEER 13 heat pump. The performance was evaluated with two different duct systems: a standard attic duct system and an indoor duct system located in a dropped-ceiling space.

NetMOD (Network Monitoring for Optimal Detection) is a Java-based software package for conducting simulation of seismic networks. Specifically, NetMOD simulates the detection capabilities of seismic monitoring networks. Network simulations have long been used to study network resilience to station outages and to determine where additional stations are needed to reduce monitoring thresholds. NetMOD makes use of geophysical models to determine the source characteristics, signal attenuation along the path between the source and station, and the performance and noise properties of the station. These geophysical models are combined to simulate the relative amplitudes of signal and noise that are observed at each of the stations. From these signal-to-noise ratios (SNR), the probability of detection can be computed given a detection threshold. This manual describes how to configure and operate NetMOD to perform seismic detection simulations. In addition, NetMOD is distributed with a simulation dataset for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) International Monitoring System (IMS) seismic network for the purpose of demonstrating NetMOD's capabilities and providing user training. The tutorial sections of this manual use this dataset when describing how to perform the steps involved when running a simulation.

Social unrest represents a major challenge for policy makers around the globe, as it can quickly escalate from small scale disturbances to highly public protests, riots and even civil war. This research was motivated by a need to understand social instability and to unpack the comments made during a spring 2013 conference hosted by Pacific Northwest National Laboratory’s Center for Global Security and the U.S. Institute for Peace, where policymakers noted that models considering social instability are often not suitable for decision-making. This analysis shows that existing state level models of instability could be improved in spatial scale to the city level, even without significantly improved data access. Better data would make this analysis more complete and likely improve the quality of the model. Another challenge with incorporating modeling into decision-making is the need to understand uncertainty in a model. Policy makers are frequently tasked with making decisions without a clear outcome, so characterization of uncertainty is critical. This report describes the work and findings of the project. It took place in three phases: a literature review of social stability research, a “hindsight scan” that looked at historical data, and a “foresight scan” looking at future scenarios.
