It then analyzes relevant issues for U.S. federal law enforcement as well as for the criminal organizations involved in producing, distributing, and profiting from the black market sale of marijuana. This report also outlines a number of related policy questions that Congress may confront. Notably, it does not discuss the legal issues associated with state-level initiatives to legalize marijuana for recreational use.

This report provides a primer on some of the fundamental aspects of the security clearance process using a "Frequently Asked Questions" format.

A letter report issued by the Government Accountability Office with an abstract that begins "With trillions of dollars in cross-border financial activity, U.S. tax authorities and others around the world exchange information with each other to administer and enforce compliance with the tax laws of their respective countries. GAO was asked to (1) identify and describe all income tax treaties and other such agreements between the United States and other countries, (2) describe the volume of exchange activity, types of information exchanged between the United States and its treaty partners, and request processing times, and (3) identify opportunities to improve the effectiveness of current U.S. information exchange processes and procedures. GAO analyzed agreement documents, IRS data on information exchanges, and interviewed program officials and the users of exchanged information."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) has considered several courses of action for the placement of the headquarters for U.S. Africa Command (AFRICOM) but decided in early 2013 to keep it in Germany. When AFRICOM was created in 2007, DOD temporarily located its headquarters in Stuttgart, Germany, with the intent of selecting a permanent location at a later date. DOD's initial goal was to locate the headquarters in Africa, but this was later abandoned in part because of significant projected costs and sensitivities on the part of African countries. Subsequently, in 2008, DOD conducted an analysis that found that several locations in Europe and the United States would be operationally feasible and less expensive than keeping the headquarters in Stuttgart. A final decision, however, was deferred until 2012, when the Cost Assessment and Program Evaluation office completed its analysis. Subsequent to this analysis, in January 2013, the Secretary of Defense decided to keep AFRICOM's headquarters in Stuttgart. In announcing the decision, the Secretary noted that keeping AFRICOM in Germany would cost more than moving it to the United States but the commander had judged it would be …

A letter report issued by the Government Accountability Office with an abstract that begins "In its April 2013 report to Congress, the Department of Defense (DOD) did not provide any new analyses, but provided the results of previous analyses related to the Aerospace Control Alert mission because, according to DOD officials, DOD was not expecting any future changes to the budget or force structure of the mission, including consideration of any basing location alternatives. DOD's April 2013 report summarized the results of three risk assessments that were conducted to support DOD's 2012 decision on which two alert basing locations could be removed from 24-hour alert status with the least amount of risk. The North American Aerospace Defense Command (NORAD), the Office of the Secretary of Defense Office of Cost Assessment and Program Evaluation, and the Continental U.S. NORAD Region performed these assessments and all concluded that, given the 2012 DOD decision that two alert basing locations would be removed from 24-hour alert status, the removal of the locations at Duluth, Minnesota, and Langley, Virginia, would provide the least increase in risk. DOD's April 2013 report also summarized a cost savings estimate developed after the decision to remove these basing locations …

A letter report issued by the Government Accountability Office with an abstract that begins "Using data agencies had reported to the Small Business Administration (SBA), GAO found that 8 of the 11 agencies participating in the Small Business Innovation Research (SBIR) program and 4 of the 5 agencies participating in the Small Business Technology Transfer (STTR) program did not consistently comply with spending requirements for fiscal years 2006 to 2011. In calculating their annual spending requirements for these programs, some agencies made improper exclusions from their extramural research and development (R&D) budgets and used differing methodologies. SBA, which oversees the programs, provided guidance in policy directives for agencies on calculating these requirements, but the directives do not provide guidance on calculating the requirements when appropriations are late and spending is delayed, resulting in agencies using differing methodologies. This made it difficult to determine whether agencies' calculations were correct. Without further SBA guidance, agencies will likely continue calculating spending requirements in differing ways."

A letter report issued by the Government Accountability Office with an abstract that begins "GAO found the Air Force, the military branch responsible for Global Positioning System (GPS) acquisition, in its report on Lower Cost Solutions for Providing Global Positioning System Capability, broadly addressed all four congressional requirements--system capability, implementation approaches, technical and programmatic risks, and estimated costs--for each option presented for the space segment. GPS consists of three segments--space, ground control, and user equipment--but the study only addressed the space segment, which accounts for the largest share of total GPS costs--more than half--in the Air Force's current budget. The Air Force identified and assessed nine options for future GPS space segments, ranging in cost from $13 billion to $25 billion from fiscal year 2013 through 2030. The report assessed each option based on a constellation or collection of 30 total satellites instead of 24, which is the Air Force's baseline GPS requirement for accuracy. This increase in total satellites raises an issue with the constellation size the Air Force intends to support in the future. Air Force officials stated that the cost analyses supporting the nine options were high-level cost estimates. Although this may be expected given the time …

A letter report issued by the Government Accountability Office with an abstract that begins "Federal agencies spend over $50 billion annually on goods and services using interagency contracts, which leverage the government's buying power, simplify procuring commonly used goods and services, and allow agencies to use the contracts and expertise of other agencies. Agencies that operate interagency contracts and provide assisted acquisition services for other agencies recover their costs by charging a fee to their customers. In response to questions about fee rates and their composition, GAO assessed for selected interagency contracting programs (1) the current fee rates and trends in the fee rates, sales, costs, and revenues; (2) the extent to which programs subsidize, or are subsidized by, other programs; (3) the extent to which agencies identify, track, and forecast costs and revenues, manage reserves, and obtain approval for fee-rate changes; and (4) the extent to which agencies use contractor personnel to supplement program staffing. GAO analyzed data on six interagency contract programs at four agencies--General Services Administration (GSA), Department of the Interior (DOI), National Aeronautics and Space Administration (NASA) and National Institutes of Health (NIH); reviewed agency policies; and interviewed officials from the agencies' program, policy, and financial …

A letter report issued by the Government Accountability Office with an abstract that begins "Reserving practices and capital requirements for the Mutual Mortgage Insurance Fund (Fund) of the Federal Housing Administration (FHA) differ in key respects from those for private mortgage insurers (PMI). These differences stem from the distinct environments in which FHA and PMIs operate, including the particular accounting principles and statutory provisions that they must follow. For example, statutory accounting principles (developed to meet the needs of insurance regulators in assessing financial condition) require PMIs to establish several reserve components, including a reserve for estimated losses expected in the near term on loans that are delinquent (loss reserve). In contrast, generally accepted accounting principles for federal entities (developed to align financial statement reporting with federal budget requirements) require FHA to reserve for the present value of estimated losses for all outstanding loans net of anticipated revenues (liability for loan guarantees). For both FHA and PMIs, capital requirements are expressed as comparisons of risk to capital, but the calculations measure risk and capital differently. Like FHA, PMIs have struggled to meet their capital requirements in recent years."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) has invested more than $63 million in 88 projects in fiscal years 2005 through 2010 to demonstrate new technology or methods addressing equipment-related corrosion. DOD's Office of Corrosion Policy and Oversight (Corrosion Office) has collected a majority of required final and follow-on reports on the results of equipment-related corrosion projects and is taking steps to obtain outstanding reports. As of May 2013, GAO found project managers had submitted final reports for 55 of the 88 projects (about 63 percent) funded in fiscal years 2005 through 2010 and submitted follow-on reports for 27 of the 41 projects (about 66 percent) funded from 2005 through 2007."

A letter report issued by the Government Accountability Office with an abstract that begins "The National Weather Service's (NWS) weather products are a vital component of the Federal Aviation Administration's (FAA) air traffic control system. In addition to providing aviation weather products developed at its own facilities, NWS also provides on-site staff at each of FAA's en route centers--the facilities that control high-altitude flight outside the airport tower and terminal areas. NWS's on-site staff is called a center weather service unit. For several years, NWS and FAA have been exploring options for improving the aviation weather services provided at en route centers. GAO agreed to (1) determine the status of the agencies' efforts to restructure aviation weather services, (2) assess the agencies' progress in establishing performance baselines in order to measure the effect of any changes, and (3) evaluate plans to address key challenges. To do so, GAO evaluated agency progress and plans and compared agency efforts with leading practices."

A letter report issued by the Government Accountability Office with an abstract that begins "GAO identified a number of proposed options for adjusting product terms and conditions to help improve the Federal Housing Administration's (FHA) long-term viability. FHA has raised the premiums that it charges borrowers several times in recent years and has taken steps to tighten its underwriting standards--for example, by setting a minimum required credit score. Some mortgage market observers have argued that further changes such as revising underwriting standards to focus on borrowers' residual income, requiring higher down payments, or reducing seller concessions (that is, funds sellers provide to buyers to help pay for closing costs) could help FHA better manage credit risk. However, such changes would entail trade-offs. For instance, some said that raising down-payment requirements would improve loan performance, but others said that this move would delay homeownership for many borrowers. Similarly, raising premiums could potentially increase revenue, but this potential would be constrained if it caused volume to decline. Further, low-risk borrowers with fewer down-payment constraints could choose less costly loans from other sources, leaving FHA with more high-risk borrowers. These changes could have a direct effect on the availability of credit for borrowers."

A letter report issued by the Government Accountability Office with an abstract that begins "The National Oceanic and Atmospheric Administration (NOAA) has completed the design of its Geostationary Operational Environmental Satellite-R (GOES-R) series and made progress in building flight and ground components. While the program reports that it is on track to stay within its $10.9 billion life cycle cost estimate, it has not reported key information on reserve funds to senior management. Also, the program has delayed interim milestones, is experiencing technical issues, and continues to demonstrate weaknesses in the development of component schedules. These factors have the potential to affect the expected October 2015 launch date of the first GOES-R satellite, and program officials now acknowledge that the launch date may be delayed by 6 months. A launch delay would increase the time that NOAA is without an on-orbit backup satellite. It would also increase the potential for a gap in GOES satellite coverage should one of the two operational satellites (GOES-14 or -15) fail prematurely - a scenario given a 36 percent likelihood of occurring by an independent review team."

This report discusses the federal mandatory minimum sentencing statutes, that limits the discretion of a sentencing court to impose a sentence that does not include a term of imprisonment or the death penalty. The United States Sentencing Commission's Mandatory Minimum Penalties in the Federal Criminal Justice System (2011) recommends consideration of amendments to several of the statutes under which federal mandatory minimum sentences are most often imposed.

This report discusses the revolution and current conflict in Libya. The current crisis was triggered in mid-February 2011 by a chain of events in Benghazi and other eastern cities that quickly spiraled out of Qadhafi's control. Although Libyan opposition groups had called for a so-called "day of rage" on February 17 to commemorate protests that had occurred five years earlier, localized violence erupted prior to the planned national protests. As of April 25, U.S. and coalition officials stated that coalition military operations had destroyed the ability of the Libyan military to control Libyan airspace and had reduced the capability of Libyan ground forces by roughly 30%-40%.

This report provides background information and oversight issues for Congress on the Coast Guard's Deepwater acquisition programs for replacing and modernizing the service's aging fleet of deepwater-capable ships and aircraft. The Coast Guard's FY2012 budget appears to request $957.2 million in acquisition funding for Deepwater programs, including $271.6 million for aircraft, $512.0 million for surface ships and boats, and $173.6 million for other items. Congress's decisions on Deepwater acquisition programs could substantially affect Coast Guard capabilities and funding requirements, as well as contractors involved in these programs.

This is the first of three papers (in addition to an introductory summary) aimed at providing a framework for evaluating future reductions or modifications of the U.S. nuclear force, first by considering previous instances in which nuclear-force capabilities were eliminated; second by looking forward into at least the foreseeable future at the features of global and regional deterrence (recognizing that new weapon systems currently projected will have expected lifetimes stretching beyond our ability to predict the future); and third by providing examples of past or possible undesirable outcomes in the shaping of the future nuclear force, as well as some closing thoughts for the future. This paper examines the circumstances and consequences of the elimination of � The INF-range Pershing II ballistic missile and Gryphon Ground-Launched Cruise Missile (GLCM), deployed by NATO under a dual-track strategy to counter Soviet intermediate-range missiles while pursuing negotiations to limit or eliminate all of these missiles. � The Short-Range Attack Missile (SRAM), which was actually a family of missiles including SRAM A, SRAM B (never deployed), and SRAM II and SRAM T, these last two cancelled during an over-budget/behind-schedule development phase as part of the Presidential Nuclear Initiatives of 1991 and 1992. � The …

During course of this project, we have worked in several areas relevant to low-dose ionizing radiation. Using gene expression to measure biological response, we have examined the response of human skin exposed in-vivo to radation, human skin exposed ex-vivo to radiation, and a human-skin model exposed to radiation. We have learned a great deal about the biological response of human skin to low-dose ionizing radiation.
