The future safety of maritime transportation in the United States-a major factor in the nation's international trade and economic well-being-will depend heavily on the quality of port and waterways information systems. Many U.S. ports and waterways lack adequate information services, although certain elements of advanced systems are now available in some locations. Barriers to improvements in information systems include the division of responsibilities for waterways management among multiple agencies at all levels of government, a lack of coordination among the federal agencies responsible for waterways management, inadequate budgets for some critical maritime programs, the high costs of some specialized technologies, stakeholder opposition to user fees, limited access to certain key data, the incompatibility of many independently developed systems, and the absence of standards for some attractive technologies.In this report, the second phase of a three-year study by the Committee on Maritime Advanced Information Systems of the National Research Council, a strategy is presented for overcoming the major barriers and deficiencies and providing a minimum level of maritime safety information nationwide. In this phase of the study, the committee concentrated on maritime information systems that promote safety, which is the area of greatest need. The committee did not examine in detail the relationship between navigation safety and maritime transportation efficiency or evaluate information systems that promote efficiency; the committee believes, however, that these issues deserve further attention.

Provides a plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community.

The commercial aviation industry is a major part of the U.S. transportation infrastructure and a key contributor to the nation's economy. The industry is facing the effects of a reduced role by the military as a source of high-quality trained personnel, particularly pilots and mechanics. At the same time, it is facing the challenges of a changing American workforce.This book is a study of the civilian training and education programs needed to satisfy the work-force requirements of the commercial aviation industry in the year 2000 and beyond, with particular emphasis on issues related to access to aviation careers by women and minorities.

Chemical signals among organisms form "e;a vast communicative interplay, fundamental to the fabric of life,"e; in the words of one expert. Chemical ecology is the the discipline that seeks to understand these interactions-to use biology in the search for new substances of potential benefit to humankind.This book highlights selected research areas of medicinal and agricultural importance. Leading experts review the chemistry ofInsect defense and its applications to pest control.Phyletic dominance--the survival success of insects.Social regulation, with ant societies as a model of multicomponent signaling systems.Eavesdropping, alarm, and deceit--the array of strategies used by insects to find and lure prey.Reproduction--from the gamete attraction to courtship nd sexual selection.The chemistry of intracellular immunosuppression.Topics also include the appropriation of dietary factors for defense and communication; the use of chemical signals in the marine environment; the role of the olfactory system in chemical analysis; and the interaction of polydnaviruses, endoparasites, and the immune system of the host.

Despite the strong safety record of the national airspace system, serious disruptions occasionally occur, often as a result of outdated or failed equipment. Under these circumstances, safety relies on the skills of the controllers and pilots and on reducing the number of aircraft in the air. The current and growing pressures to increase the capacity to handle a greater number of flights has led to a call for faster and more powerful equipment and for equipment that can take over some of the tasks now being performed by humans. Increasing the role of automation in air traffic control may provide a more efficient system, but will human controllers be able to effectively take over when problems occur? This comprehensive volume provides a baseline of knowledge about the capabilities and limitations of humans relative to the variety of functions performed in air traffic control. It focuses on balancing safety with the expeditious flow of air traffic, identifying lessons from past air accidents. The book discussesThe function of the national airspace system and the procedures for hiring, training, and evaluating controllers.Decisionmaking, memory, alertness, vigilance, sleep patterns during shift work, communication, and other factors in controllers' performance.Research on automation and human factors in air traffic control and incorporation of findings into the system.The Federal Aviation Administration's management of the air traffic control system and its dual mandate to promote safety and the development of air commerce.This book also offers recommendations for evaluation the human role in automated air traffic control systems and for managing the introduction of automation into current facilities and operations. It will be of interest to anyone concerned about air safety--policymakers, regulators, air traffic managers and controllers, airline officials, and passenger advocates.

How can we understand and rise to the environmental challenges of global change? This book offers a comprehensive overview of global change research, and provides a framework for answering questions. It highlights the research imperatives and strategies for investigators in the areas of atmospheric chemistry, climate, ecosystem studies, and more.

Each year, child protective services receive reports of child abuse and neglect involving six million children, and many more go unreported. The long-term human and fiscal consequences of child abuse and neglect are not relegated to the victims themselves -- they also impact their families, future relationships, and society. In 1993, the National Research Council (NRC) issued the report, Under-standing Child Abuse and Neglect, which provided an overview of the research on child abuse and neglect. New Directions in Child Abuse and Neglect Research updates the 1993 report and provides new recommendations to respond to this public health challenge. According to this report, while there has been great progress in child abuse and neglect research, a coordinated, national research infrastructure with high-level federal support needs to be established and implemented immediately.New Directions in Child Abuse and Neglect Research recommends an actionable framework to guide and support future child abuse and neglect research. This report calls for a comprehensive, multidisciplinary approach to child abuse and neglect research that examines factors related to both children and adults across physical, mental, and behavioral health domains--including those in child welfare, economic support, criminal justice, education, and health care systems--and assesses the needs of a variety of subpopulations. It should also clarify the causal pathways related to child abuse and neglect and, more importantly, assess efforts to interrupt these pathways. New Directions in Child Abuse and Neglect Research identifies four areas to look to in developing a coordinated research enterprise: a national strategic plan, a national surveillance system, a new generation of researchers, and changes in the federal and state programmatic and policy response.

The blowout of the Macondo well on April 20, 2010, led to enormous consequences for the individuals involved in the drilling operations, and for their families. Eleven workers on the Deepwater Horizon drilling rig lost their lives and 16 others were seriously injured. There were also enormous consequences for the companies involved in the drilling operations, to the Gulf of Mexico environment, and to the economy of the region and beyond. The flow continued for nearly 3 months before the well could be completely killed, during which time, nearly 5 million barrels of oil spilled into the gulf.Macondo Well-Deepwater Horizon Blowout examines the causes of the blowout and provides a series of recommendations, for both the oil and gas industry and government regulators, intended to reduce the likelihood and impact of any future losses of well control during offshore drilling. According to this report, companies involved in offshore drilling should take a "e;system safety"e; approach to anticipating and managing possible dangers at every level of operation -- from ensuring the integrity of wells to designing blowout preventers that function under all foreseeable conditions-- in order to reduce the risk of another accident as catastrophic as the Deepwater Horizon explosion and oil spill. In addition, an enhanced regulatory approach should combine strong industry safety goals with mandatory oversight at critical points during drilling operations.Macondo Well-Deepwater Horizon Blowout discusses ultimate responsibility and accountability for well integrity and safety of offshore equipment, formal system safety education and training of personnel engaged in offshore drilling, and guidelines that should be established so that well designs incorporate protection against the various credible risks associated with the drilling and abandonment process. This book will be of interest to professionals in the oil and gas industry, government decision makers, environmental advocacy groups, and others who seek an understanding of the processes involved in order to ensure safety in undertakings of this nature.
