Maritime Security: Varied Actions Taken to Enhance Cruise Ship Security, but Some Concerns Remain (open access)

Maritime Security: Varied Actions Taken to Enhance Cruise Ship Security, but Some Concerns Remain

A letter report issued by the Government Accountability Office with an abstract that begins "Over 9 million passengers departed from U.S. ports on cruise ships in 2008, and according to agency officials, cruise ships are attractive terrorist targets. GAO was asked to review cruise ship security, and this report addresses the extent to which (1) the Coast Guard, the lead federal agency on maritime security, assessed risk in accordance with the Department of Homeland Security's (DHS) guidance and identified risks; and (2) federal agencies, cruise ship and facility operators, and law enforcement entities have taken actions to protect cruise ships and their facilities. GAO reviewed relevant requirements and agency documents on maritime security, analyzed 2006 through 2008 security operations data, interviewed federal and industry officials, and made observations at seven ports. GAO selected these locations based on factors such as the number of sailings from each port. Results of the visits provided additional information on security, but were not projectable to all ports."

Government Efficiency And Effectiveness: Opportunities to Reduce Fragmentation, Overlap, and Duplication and Achieve Other Financial Benefits (open access)

Government Efficiency And Effectiveness: Opportunities to Reduce Fragmentation, Overlap, and Duplication and Achieve Other Financial Benefits

Testimony issued by the Government Accountability Office with an abstract that begins "In summary, GAO's 2013 annual report identifies 31 new areas where agencies may be able to achieve greater efficiency or effectiveness. Within these 31 areas, GAO identifies 81 actions that the executive branch or Congress could take to address the issues GAO identified. Although it may be appropriate for multiple agencies or entities to be involved in the same programmatic or policy area due to the nature or magnitude of the federal effort, GAO's report includes 17 areas of fragmentation, overlap, or duplication where multiple programs and activities may be creating inefficiencies. The report also identifies 14 additional areas where opportunities exist to achieve cost savings or enhance revenue collections."

Workplace Safety and Health: Better OSHA Guidance Needed on Safety Incentive Programs (open access)

Workplace Safety and Health: Better OSHA Guidance Needed on Safety Incentive Programs

A letter report issued by the Government Accountability Office with an abstract that begins "Little research exists on the effect of workplace safety incentive programs and other workplace safety policies on workers' reporting of injuries and illnesses, but several experts identified a link between certain types of programs and policies and reporting. Researchers distinguish between rate-based safety incentive programs, which reward workers for achieving low rates of reported injuries or illnesses, and behavior-based programs, which reward workers for certain behaviors, such as recommending safety improvements. Of the six studies GAO identified that assessed the effect of safety incentive programs, two analyzed the potential effect on workers’ reporting of injuries or illnesses, but they concluded that there was no relationship between the programs and injury and illness reporting. Experts and industry officials, however, suggest that rate-based programs may discourage reporting of injuries and illnesses. Experts and industry officials also reported that certain workplace polices, such as post-incident drug and alcohol testing, may discourage workers from reporting injuries and illnesses. Researchers and workplace safety experts also noted that how safety is managed in the workplace, including employer practices such as fostering open communication about safety issues, may encourage reporting of injuries and …

Health Care Workforce: Federal Investments in Training and the Availability of Data for Workforce Projections (open access)

Health Care Workforce: Federal Investments in Training and the Availability of Data for Workforce Projections

Testimony issued by the Government Accountability Office with an abstract that begins "GAO found that there is substantial federal funding for health care workforce training programs but that obtaining comprehensive information about the scope of such programs is challenging. In GAO's August 2013 report on the federal role in health care workforce training, GAO found that four federal departments—the Department of Health and Human Services (HHS), the Department of Veterans Affairs (VA), the Department of Defense (DOD), and the Department of Education (Education)—administered 91 programs that supported postsecondary training or education specifically for direct care health professionals in fiscal year 2012. All together, the four departments reported obligating about $14.2 billion for health care workforce training programs in fiscal year 2012, with HHS funding the most programs (69) and having the largest percentage of total reported funding (82 percent). The majority of funding for health care workforce training in fiscal year 2012—about $11.1 billion, or 78 percent—was invested in seven programs that supported postgraduate residency training for physicians, dentists, and certain other health professionals, called Graduate Medical Education. The remaining 84 programs administered by HHS, VA, DOD, and Education accounted for obligations of about $3.2 billion and provided varying levels …

VA Health Care: Ongoing and Past Work Identified Access Problems That May Delay Needed Medical Care for Veterans (open access)

VA Health Care: Ongoing and Past Work Identified Access Problems That May Delay Needed Medical Care for Veterans

Testimony issued by the Government Accountability Office with an abstract that begins "GAO's ongoing work examining VHA's management of outpatient specialty care consults identified examples of delays in veterans receiving outpatient specialty care, as well as limitations in the Department of Veterans Affairs' (VA), Veterans Health Administration's (VHA) implementation of new consult business rules designed to standardize aspects of the clinical consult process. For example, for 4 of the 10 physical therapy consults GAO reviewed for one VAMC, between 108 and 152 days elapsed with no apparent actions taken to schedule an appointment for the veteran. For 1 of these consults, several months passed before the veteran was referred for care to a non-VA health care facility. VA medical center (VAMC) officials cited increased demand for services, and patient no-shows and cancelled appointments among the factors that lead to delays and hinder their ability to meet VHA's guideline of completing consults within 90 days of being requested. GAO's ongoing work also identified variation in how the five VAMCs reviewed have implemented key aspects of VHA's business rules, such as strategies for managing future care consults—requests for specialty care appointments that are not clinically needed for more than 90 days. Such …

Defense Infrastructure: In-Kind Projects Initiated during Fiscal Years 2011 and 2012 (open access)

Defense Infrastructure: In-Kind Projects Initiated during Fiscal Years 2011 and 2012

Correspondence issued by the Government Accountability Office with an abstract that begins "The Department of Defense’s (DOD) processes for selecting in-kind projects in Asia vary by country and by whether the project is intended to support force structure initiatives or enduring installations, although these efforts are not mutually exclusive; domestically, DOD’s processes for selecting in-kind projects vary by military service and statutory authority. In Asia, the selection of in-kind projects to support initiatives for relocating U.S. troops within Japan and the Republic of Korea generally results from a schedule-driven process based on resources and infrastructure made available by the host nation to fulfill initiatives agreed to in prior years with target dates for completion, and input from affected military bases. The selection of in-kind projects to support enduring installations is characterized by priority-based processes with input from installations and unit commanders. All in-kind projects to support U.S. forces in Asia result from host nation support as agreed to bilaterally, with the exception of facilities provided through the Japan Facilities Improvement Program, which is a voluntary effort on the part of Japan. All DOD facility planning and project selection at enduring locations is based on military and operational requirements, independent of …

Presidential Helicopter Acquisition: Program Makes Progress in Balancing Requirements, Costs, and Schedule

A letter report issued by the Government Accountability Office with an abstract that begins "The Navy made progress in the past year in establishing a sound VXX business case that reflects a rational balance between requirements, costs and schedule. In 2012, the Navy completed an updated Analysis of Alternatives (AOA) based on refined requirements and an acquisition approach that would leverage mature technologies from outside the program onto an in-production commercial or military airframe--allowing the program to begin in the engineering and manufacturing development phase of the Department of Defense's (DOD) acquisition process. The 2012 AOA reflected additional trade-offs made among cost, schedule, risk, and performance. Some key performance requirements changed from the terminated VH-71 program to the VXX."

Military Munitions Response Program: Opportunities Exist to Improve Program Management (open access)

Military Munitions Response Program: Opportunities Exist to Improve Program Management

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) established the military munitions response program (MMRP) in 2001 to clean up sites known to be or suspected of being contaminated with military munitions and related hazardous substances. Cleanup of sites on active and base realignment and closure installations is the responsibility of the military service--Air Force, Army, Navy, or Marine Corps--that currently controls the land, and the Army has delegated execution of cleanup of formerly used defense sites (FUDS) to the U.S. Army Corps of Engineers (Corps). GAO was mandated to assess the (1) MMRP staffing and funding levels; (2) progress DOD has made in cleaning up munitions response sites; (3) extent to which DOD has established MMRP performance goals; and (4) extent to which DOD collects data on factors influencing project duration, as well as the accuracy of its cleanup cost estimates. GAO analyzed MMRP data and DOD documents and interviewed officials from DOD, the military services, and the Corps."

Social Security Disability Programs: SSA Could Take Steps to Improve Its Assessment of Continued Eligibility (open access)

Social Security Disability Programs: SSA Could Take Steps to Improve Its Assessment of Continued Eligibility

Testimony issued by the Government Accountability Office with an abstract that begins "The Social Security Administration (SSA) reported in January 2014 that it is behind schedule in assessing the continued eligibility of recipients in its two disability programs, Disability Insurance (DI) and Supplemental Security Income (SSI),and has accumulated a backlog of 1.3 million continuing disability reviews (CDRs). From fiscal years 2000 to 2011, the numbers of adult and child CDRs conducted fell about 70 percent. Children make up about one fifth of all SSI recipients, and GAO reported in 2012 that many of their CDRs were overdue. For example, more than 24,000 CDRs for children with mental impairments were overdue by 6 or more years, including over 6,000 CDRs for children who were expected to medically improve within 6 to 18 months of their initial determination. GAO also identified several cases which exceeded their scheduled review date by 13 years or more. When CDRs are not conducted as scheduled, the potential for improper payments increases as some recipients receive benefits for which they are no longer eligible. In September 2011, SSA's Office of the Inspector General estimated that SSA had paid about $1.4 billion in SSI benefits to children who …

Superfund: EPA Should Take Steps to Improve Its Management of Alternatives to Placing Sites on the National Priorities List (open access)

Superfund: EPA Should Take Steps to Improve Its Management of Alternatives to Placing Sites on the National Priorities List

A letter report issued by the Government Accountability Office with an abstract that begins "The Environmental Protection Agency (EPA) most commonly addresses the cleanup of sites it has identified as eligible for the National Priorities List (NPL) by deferring oversight of the cleanup to approaches outside of the Superfund program. As of December 2012, of the 3,402 sites EPA identified as potentially eligible, EPA has deferred oversight of 1,984 sites to approaches outside the Superfund program, including 1,766 Other Cleanup Activity (OCA) deferrals to states and other entities. However, EPA has not issued guidance for OCA deferrals as it has for the other cleanup approaches. Moreover, EPA's program guidance does not clearly define each type of OCA deferral or specify in detail the documentation EPA regions should have to support their decisions on OCA deferrals. Without clearer guidance on OCA deferrals, EPA cannot be reasonably assured that its regions are consistently tracking these sites or that their documentation will be appropriate or sufficient to verify that these sites have been deferred or have completed cleanup. Under the Superfund program, EPA oversees the cleanup of 1,313 sites on the NPL, 67 sites under the Superfund Alternative (SA) approach, and at least …

Mine Safety: Basis for Proposed Exposure Limit on Respirable Coal Mine Dust and Possible Approaches for Lowering Dust Levels (open access)

Mine Safety: Basis for Proposed Exposure Limit on Respirable Coal Mine Dust and Possible Approaches for Lowering Dust Levels

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Labor's Mine Safety and Health Administration (MSHA) appropriately did not use recent trend data on coal workers' pneumoconiosis (CWP) as a basis for its proposal to lower the permissible exposure limit for respirable coal mine dust. These recent data from the Department of Health and Human Services' National Institute for Occupational Safety and Health (NIOSH) are inappropriate for this purpose because they do not include the types of detailed information about individual miners needed to estimate the likelihood that miners would develop CWP at different exposure levels, such as historical dust exposures. MSHA primarily based its proposed new limit on two reports and six epidemiologic studies, which each concluded that lowering the limit on exposure to coal mine dust would reduce miners' risk of developing disease. MSHA's proposed coal mine dust limit was supported by these reports and studies because, unlike recent CWP trend data, they included information needed to conduct a reliable epidemiological analysis of disease risks associated with different levels of exposure to coal mine dust."

Toward fully self-consistent simulation of the interaction of E-Clouds and beams with WARP-POSINST (open access)

Toward fully self-consistent simulation of the interaction of E-Clouds and beams with WARP-POSINST

To predict the evolution of electron clouds and their effect on the beam, the high energy physics community has relied so far on the complementary use of 'buildup' and 'single/multi-bunch instability' reduced descriptions. The former describes the evolution of electron clouds at a given location in the ring, or 'station', under the influence of prescribed beams and external fields [1], while the latter (sometimes also referred as the 'quasi-static' approximation [2]) follows the interaction between the beams and the electron clouds around the accelerator with prescribed initial distributions of electrons, assumed to be concentrated at a number of discrete 'stations' around the ring. Examples of single bunch instability codes include HEADTAIL [3], QuickPIC [4, 5], and PEHTS [6]. By contrast, a fully self-consistent approach, in which both the electron cloud and beam distributions evolve simultaneously under their mutual influence without any restriction on their relative motion, is required for modeling the interaction of high-intensity beams with electron clouds for heavy-ion beam-driven fusion and warm-dense matter science. This community has relied on the use of Particle-In-Cell (PIC) methods through the development and use of the WARP-POSINST code suite [1, 7, 8]. The development of novel numerical techniques (including adaptive mesh refinement, …
