The security of the U.S. commercial aviation system has been a growing concern since the 1970's when the hijacking of aircraft became a serious problem. Over that period, federal aviation officials have been searching for more effective ways for non-invasive screening of passengers, luggage, and cargo to detect concealed explosives and weapons. To assist in this effort, the Transportation Security Administration (TSA) asked the NRC for a study of emerging screening technologies. This book - the fourth of four - focuses on data fusion as a means to significantly improve the ability of the existing suite of airport detection systems and access control systems to detect and prevent attacks. The book presents a discussion of the data fusion, an analysis of current data fusion efforts, and an assessment of data fusion opportunities for various airport security activities.

On November 19, 2001 the Transportation Security Administration (TSA) was created as a separate entity within the U.S. Department of Transportation through the Aviation and Transportation Security Act. The act also mandated that all checked baggage on U.S. flights be scanned by explosive detection systems (EDSs) for the presence of threats. These systems needed to be deployed quickly and universally, but could not be made available everywhere. As a result the TSA emphasized the procurement and installation of certified systems where EDSs were not yet available. Computer tomography (CT)-based systems became the certified method or place-holder for EDSs. CT systems cannot detect explosives but instead create images of potential threats that can be compared to criteria to determine if they are real threats. The TSA has placed a great emphasis on high level detections in order to slow false negatives or missed detections. As a result there is abundance in false positives or false alarms. In order to get a better handle on these false positives the National Research Council (NRC) was asked to examine the technology of current aviation-security EDSs and false positives produced by this equipment. The ad hoc committee assigned to this task examined and evaluated the cases of false positives in the EDSs, assessed the impact of false positive resolution on personnel and resource allocation, and made recommendations on investigating false positives without increase false negatives. To complete their task the committee held four meetings in which they observed security measures at the San Francisco International Airport, heard from employees of DHS and the TSA. Engineering Aviation Security Environments-Reduction of False Alarms in Computed Tomography-Based Screening of Checked Baggage is the result of the committee's investigation. The report includes key conclusions and findings, an overview of EDSs, and recommendations made by the committee.

The response of the U.S. federal government to the events of September 11, 2001 has reflected the challenge of striking a balance between implementing security measures to deter terrorist attacks while at the same time limiting disruption to air commerce. Airport and Aviation Security: U.S. Policy and Strategy in the Age of Global Terrorism is a co

This new book from the National Research Council finds serious weaknesses in the government's plan for research on the potential health and environmental risks posed by nanomaterials, which are increasingly being used in consumer goods and industry. An effective national plan for identifying and managing potential risks is essential to the successful development and public acceptance of nanotechnology-enabled products. The book recommends a robust national strategic plan for addressing nanotechnology-related EHS risks, which will need to focus on promoting research that can assist all stakeholders, including federal agencies, in planning, controlling, and optimizing the use of engineered nanomaterials while minimizing EHS effects of concern to society. Such a plan will ensure the timely development of engineered nanoscale materials that will bring about great improvements in the nation's health, its environmental quality, its economy, and its security.

Insecure transportation systems are costing our worldwide mobility-based economy as much as 6% of GDP annually. The effectiveness of security measures vary widely. In the United States, depending on the mode of transportation, it ranges from "medium effectiveness for airports to "low effectiveness for maritime, rail, transit, and intermodal activities. Situational awareness and interoperability are lacking as we try to deal with both natural and man-made disasters. Regardless of the transport mode, improvements are essential if governments and corporations are to address security planning, response, and national preparedness. Transportation Security examines this problem in a comprehensive manner and addresses security-based technologies and solutions to minimize risk.* Covers air, sea, roadway, rail and public transport modes* Offers technological solutions for mobility based problems in planning, logistics and policy to improve security, combat terrorism and ensure national preparedness* Includes work of international experts & global examples related to transportation security

Despite the increase in funding for research and the rising numbers of peer-reviewed publications over the past decade that address the environmental, health, and safety aspects of engineered nanomaterials (ENMs), uncertainty about the implications of potential exposures of consumers, workers, and ecosystems to these materials persists. Consumers and workers want to know which of these materials they are exposed to and whether the materials can harm them. Industry is concerned about being able to predict with sufficient certainty whether products that it makes and markets will pose any environmental, health or safety issues and what measures should be taken regarding manufacturing practices and worldwide distribution to minimize any potential risk. However, there remains a disconnect between the research that is being carried out and its relevance to and use by decision-makers and regulators to make informed public health and environmental policy and regulatory decisions. Research Progress on Environmental, Health, and Safety Aspects of Nanomaterials evaluates research progress and updates research priorities and resource estimates on the basis of results of studies and emerging trends in the nanotechnology industry. This report follows up the 2012 report A Research Strategy for Environmental, Health, and Safety Aspects of Engineered Nanomaterials, which presented a strategic approach for developing the science and research infrastructure needed to address uncertainties regarding the potential environmental, health, and safety risks posed by ENMs. This new report looks at the state of nanotechnology research, examines market and regulatory conditions and their affect on research priorities, and considers the criteria for evaluating research progress on the environmental, health, and safety aspects of nanotechnology.

The nanotechnology sector, which generated about $225 billion in product sales in 2009, is predicted to expand rapidly over the next decade with the development of new technologies that have new capabilities. The increasing production and use of engineered nanomaterials (ENMs) may lead to greater exposures of workers, consumers, and the environment, and the unique scale-specific and novel properties of the materials raise questions about their potential effects on human health and the environment. Over the last decade, government agencies, academic institutions, industry, and others have conducted many assessments of the environmental, health, and safety (EHS) aspects of nanotechnology. The results of those efforts have helped to direct research on the EHS aspects of ENMs. However, despite the progress in assessing research needs and despite the research that has been funded and conducted, developers, regulators, and consumers of nanotechnology-enabled products remain uncertain about the types and quantities of nanomaterials in commerce or in development, their possible applications, and their associated risks. A Research Strategy for Environmental, Health, and Safety Aspects of Engineered Nanomaterials presents a strategic approach for developing the science and research infrastructure needed to address uncertainties regarding the potential EHS risks of ENMs. The report summarizes the current state of the science and high-priority data gaps on the potential EHS risks posed by ENMs and describes the fundamental tools and approaches needed to pursue an EHS risk research strategy. The report also presents a proposed research agenda, short-term and long-term research priorities, and estimates of needed resources and concludes by focusing on implementation of the research strategy and evaluation of its progress, elements that the committee considered integral to its charge.

The Centers for Medicare and Medicaid Services (CMS) is the agency in the Department of Health and Human Services responsible for providing health coverage for seniors and people with disabilities, for limited-income individuals and families, and for children-totaling almost 100 million beneficiaries. The agency's core mission was established more than four decades ago with a mandate to focus on the prompt payment of claims, which now total more than 1.2 billion annually. With CMS's mission expanding from its original focus on prompt claims payment come new requirements for the agency's information technology (IT) systems. Strategies and Priorities for Information Technology at the Centers for Medicare and Medicaid Services reviews CMS plans for its IT capabilities in light of these challenges and to make recommendations to CMS on how its business processes, practices, and information systems can best be developed to meet today's and tomorrow's demands. The report's recommendations and conclusions offered cluster around the following themes: (1) the need for a comprehensive strategic technology plan; (2) the application of an appropriate metamethodology to guide an iterative, incremental, and phased transition of business and information systems; (3) the criticality of IT to high-level strategic planning and its implications for CMS's internal organization and culture; and (4) the increasing importance of data and analytical efforts to stakeholders inside and outside CMS. Given the complexity of CMS's IT systems, there will be no simple solution. Although external contractors and advisory organizations will play important roles, CMS needs to assert well-informed technical and strategic leadership. The report argues that the only way for CMS to succeed in these efforts is for the agency, with its stakeholders and Congress, to recognize resolutely that action must be taken, to begin the needed cultural and organizational transformations, and to develop the appropriate internal expertise to lead the initiative with a comprehensive, incremental, iterative, and integrated approach that effectively and strategically integrates business requirements and IT capabilities.

Increasingly, the core mission of the Centers for Medicare and Medicaid Services (CMS), an agency of the Department of Health and Human Services, is expanding from one of focusing on prompt claims payment to one of becoming more broadly involved in improving health care quality and efficiency. The requirements for the information technology (IT) systems of CMS are changing as its mission changes, and the efforts to evolve its systems from those designed to support the agency's historical mission come in the midst of a push to modernize the nation's health care IT more broadly. These new challenges arise even as CMS must meet challenging day-to-day operational requirements and make frequent adjustments to its business processes, code, databases, and systems in response to changing statutory, regulatory, and policy requirements. In light of these and other emerging challenges, CMS asked the National Research Council to conduct a study that would lay out a forward-looking vision for the Centers for Medicare and Medicaid Services, taking account of CMS's mission, business processes, and information technology requirements. The study is being conducted in two phases. The first, resulting in the present volume, draws on a series of teleconferences, briefings, and an information-gathering workshop held in Washington, D.C., on September 27-28, 2010. The second phase, drawing on that workshop and on additional briefings, site visits, and committee deliberations, will result in a final report with recommendations, to be issued at the end of the project in 2011.
