Review Of Recreational Fisheries Survey Methods
by National Research Council of the National AcademiesRecreational fishing in the United States is an important social and economic component of many marine fisheries, with an estimated 14 million anglers making almost 82 million fishing trips in 2004. Although each individual angler typically harvests a small number of fish, collectively these sport fisheries can take a significant fraction of the yearly catch--in some cases more than commercial fisheries. For example, in 1999, recreational fishing accounted for 94% of the total catch of spotted sea trout, 76% of striped bass and sheephead, and 60 percent of king mackerel. It is important that systems used to monitor fishing catch are adequate for timely management of recreational fisheries. However, the large number of anglers and access points makes monitoring recreational fishing much more difficult than monitoring commercial fishing. This report reviews the types of survey methods used to estimate catch in recreational fisheries, including state/federal cooperative programs. The report finds that both telephone survey and onsite access components of the current monitoring systems have serious flaws in design or implementation. There are also several areas of miscommunication and mismatched criteria among designers of surveys, data collectors, and recreational fisheries. The report recommends that a comprehensive, universal sampling frame with national coverage should be established, and that improvements should be made in statistical analysis of the data collected and in the ways the data are communicated. A permanent and independent research group should be established and funded to evaluate the statistical design and adequacy of recreational fishery surveys and to guide necessary modifications or new initiatives.
Review Of The Army's Technical Guides On Assessing And Managing Chemical Hazards To Deployed Personnel
by Subcommittee on the Toxicological Risks to Deployed Military PersonnelTo guide mission planning, military decision makers need information on the health risks of potential exposures to individual soldiers and their potential impact on mission operations. To help with the assessment of chemical hazards, the U.S. Army Center for Health Promotion and Preventive Medicine developed three technical guides for characterizing chemicals in terms of their risks to the mission and to the health of the force. The report reviews these guides for their scientific validity and conformance with current risk-assessment practices. The report finds that the military exposure guidelines are appropriate (with some modification) for providing force health protection, but that for assessing mission risk, a new set of exposure guidelines is needed that predict concentrations at which health effects would degrade the performance of enough soldiers to hinder mission accomplishment.

Review and Integration of Biosphere-Atmosphere Modelling of Reactive Trace Gases and Volatile Aerosols
by Raia-Silva Massad Benjamin LoubetWhen considering biosphere-atmosphere exchange of trace gases and volatile aerosols, significant advances have been made both from an experimental and modelling point of view and on several scales. This was particularly stimulated by the availability of new datasets generated from improvements in analytical methods and flux measurement techniques. Recent research advances allow us, not only to identify major mechanisms and factors affecting the exchanges between the biosphere and the atmosphere, but also to recognize several gaps in the methodologies used in accounting for emissions and deposition in landscape and global scale models. This work aims at (i) reviewing exchange processes and modelling schemes, parameterisations and datasets, (ii) presenting a common conceptual framework to model soil-vegetation-atmosphere exchange of reactive trace gases and aerosols accounting for in-canopy transfer chemical interactions and (iii) discussing the key elements of the agreed framework.
Review of Army Research Laboratory Programs for Historically Black Colleges and Universities and Minority Institutions
by Committee on Review of Army Research Laboratory Programs for Historically Black Colleges Universities Minority Institutions"Review of Army Research Laboratory Programs for Historically Black Colleges and Universities and Minority Institutions" examines the ways in which historically black colleges and universities and minority institutions have used the Army Research Laboratory (ARL) funds to enhance the science, technology, engineering, and mathematics (STEM) programs at their institutions over the past decade. This report also considers which program elements reflect practices that are effective for assisting these institutions in enhancing the STEM programs and could be considered by other Department of Defense agencies for application to their programs. The Army Research Laboratory has contributed to building up the human and infrastructural capacities in the past, and this report looks for ways to enhance ARL program impact on institution-building in the future, confident that more capable black and minority-serving institutions will, in turn, help America as a whole develop a more diverse and intellectually capable STEM workforce.
Review of Biotreatment, Water Recovery, and Brine Reduction Systems for the Pueblo Chemical Agent Destruction Pilot Plant
by Committee on Review of Biotreatment Water Recovery Brine Reduction Systems for the Pueblo Chemical Agent Destruction Pilot PlantThe Pueblo Chemical Depot (PCD) in Colorado is one of two sites that features U. S. stockpile of chemical weapons that need to be destroyed. The PCD features about 2,600 tons of mustard-including agent. The PCD also features a pilot plant, the Pueblo Chemical Agent Destruction Pilot Plant (PCAPP), which has been set up to destroy the agent and munition bodies using novel processes. The chemical neutralization or hydrolysis of the mustard agent produces a Schedule 2 compound called thiodiglycol (TDG) that must be destroyed. The PCAPP uses a combined water recovery system (WRS) and brine reduction system (BRS) to destroy TDG and make the water used in the chemical neutralization well water again. Since the PCAPP is using a novel process, the program executive officer for the Assembled Chemical Weapons Alternatives (ACWA) program asked the National Research Council (NRC) to initiate a study to review the PCAPP WRS-BRS that was already installed at PCAPP. 5 months into the study in October, 2012, the NRC was asked to also review the Biotreatment area (BTA). The Committee on Review of Biotreatment, Water Recovery, and Brine Reduction Systems for the Pueblo Chemical Agent Destruction Pilot Plant was thus tasked with evaluating the operability, life-expectancy, working quality, results of Biotreatment studies carried out prior to 1999 and 1999-2004, and the current design, systemization approached, and planned operation conditions for the Biotreatment process. Review of Biotreatment, Water Recovery, and Brine Reduction Systems for the Pueblo Chemical Agent Destruction Pilot Plant is the result of the committee's investigation. The report includes diagrams of the Biotreatment area, the BRS, and WRS; a table of materials of construction, the various recommendations made by the committee; and more.
Review of Department of Defense Test Protocols for Combat Helmets
by Committee on Review of Test Protocols Used by the DoD to Test Combat HelmetsCombat helmets have evolved considerably over the years from those used in World War I to today's Advanced Combat Helmet. One of the key advances was the development of aramid fibers in the 1960s, which led to today's Kevlar-based helmets. The Department of Defense is continuing to invest in research to improve helmet performance, through better design and materials as well as better manufacturing processes. Review of the Department of Defense Test Protocols for Combat Helmets considers the technical issues relating to test protocols for military combat helmets. At the request of the DOD Director of Operational Test and Evaluation, this report evaluates the adequacy of the Advanced Combat Helmet test protocol for both first article testing and lot acceptance testing, including its use of the metrics of probability of no penetration and the upper tolerance limit (used to evaluate backface deformation). The report evaluates appropriate use of statistical techniques in gathering data; adequacy of current helmet testing procedures; procedures for the conduct of additional analysis of penetration and backface deformation data; and scope of characterization testing relative to the benefit of the information obtained.
Review of EPA Homeland Security Efforts: Safe Buildings Program Research Implementation Plan
by Committee on Safe Buildings ProgramThe report examines the Environmental Protection Agency’s three-year plan for a comprehensive response to a chemical or biological attack on a civilian or public sector facility. The report states that EPA has correctly identified the essential major research areas (detection, containment, decontamination, and disposal) but calls for an initial focus on decontamination and disposal efforts and a longer term research program.

Review of International Technologies for Destruction of Recovered Chemical Warfare Materiel
by National Research Council of the National AcademiesThe Chemical Weapons Convention requires, among other things, that the signatories to the convention--which includes the United States--destroy by April 29, 2007, or as soon possible thereafter, any chemical warfare materiel that has been recovered from sites where it has been buried once discovered. For several years the United States and several other countries have been developing and using technologies to dispose of this non-stockpile materiel. To determine whether international efforts have resulted in technologies that would benefit the U.S. program, the U.S. Army asked the NRC to evaluate and compare such technologies to those now used by the United States. This book presents a discussion of factors used in the evaluations, summaries of evaluations of several promising international technologies for processing munitions and for agent-only processing, and summaries of other technologies that are less likely to be of benefit to the U.S. program at this time.

The information is largely based on the BIOCAT database, originally developed by the late D. J. Greathead (former director of the International Institute of Biological Control, now part of CABI) and updated by CABI scientists.
Review of NOAA Working Group: Report on Long-Term Satellite Total Solar Irradiance Observation
by National Research Council of the National AcademiesSolar irradiance provides the only significant source of energy input to the climate system and its variability has the potential to either mitigate or exacerbate anthropogenic change. Maintaining an unbroken record of Total Solar Irradiance (TSI) is critical in resolving ongoing debates regarding the potential role of solar variability in influencing Earth’s climate. <P> Space-borne instruments have acquired TSI data since 1978. Currently, the best calibrated and lowest noise source of TSI measurements is the Total Irradiance Monitor (TIM) onboard NASA’s Solar Radiation and Climate Experiment (SORCE). These TIM-era data are of higher quality than the older data in the full record. Thus, the TSI climate data record (CDR) has two components. There is the shorter, but more accurate record of the TIM era and the full (33+ year) space-based TSI measurement record. Both are important and require preservation. <P><P> SORCE is well past its design life and is encountering significant battery degradation. The Total Solar Irradiance Sensor (TSIS), a dual-instrument package that will be flown on the Joint Polar Satellite System (JPSS) Free Flyer 1 (FF-1) mission to continue the TSI record, is not scheduled to launch until late 2016 or early 2017, creating the potential for a data gap. Unfortunately, NASA’s Glory spacecraft, which carried a TIM that would have provided a gap filler, failed to reach orbit on March 4, 2011. Without a mitigation plan, the continuity of both data records (the TIM-era and full record) is threatened.
Review of Northeast Fishery Stock Assessments
by Committee to Review Northeast Fishery Stock AssessmentsThe collapse of cod, flounder, and haddock fish stocks in the Northeast United States has caused widespread concern among managers and fishers in the United States and Canada. The diminishing stocks have forced managers to take strict regulatory measures. Numerous questions have been raised about the adequacy of stock assessment science used to evaluate the status of these stocks and the appropriateness of the management measures taken. Based on these concerns, Congress mandated that a scientific review of the methodology and data used to evaluate these stocks be conducted. In this volume, the committee concludes that although there are improvements to be made in data collection, modeling uncertainty, and communicating between fishers, managers, and scientists, the scientific methods used in the Northeast stock assessments are sound. Recommendations are made on how the stock assessment process can be improved.

Review of WIC Food Packages: Final Report
by Engineering Medicine National Academies of SciencesThe Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) began 40 years ago as a pilot program and has since grown to serve over 8 million pregnant women, and mothers of and their infants and young children. Today the program serves more than a quarter of the pregnant women and half of the infants in the United States, at an annual cost of about $6.2 billion. Through its contribution to the nutritional needs of pregnant, breastfeeding, and post-partum women; infants; and children under 5 years of age; this federally supported nutrition assistance program is integral to meeting national nutrition policy goals for a significant portion of the U.S. population. To assure the continued success of the WIC, Congress mandated that the Food and Nutrition Service of the U.S. Department of Agriculture (USDA) reevaluate the program’s food packages every 10 years. In 2014, the USDA asked the Institute of Medicine to undertake this reevaluation to ensure continued alignment with the goals of the Dietary Guidelines for Americans. In this third report, the committee provides its final analyses, recommendations, and the supporting rationale.
Review of the Bureau of Reclamation's Corrosion Prevention Standards for Ductile Iron Pipe
by National Research Council of the National AcademiesDuctile iron pipe (DIP) was introduced about 50 years ago as a more economical and better-performing product for water transmission and distribution. As with iron or steel pipes, DIP is subject to corrosion, the rate of which depends on the environment in which the pipe is placed. Corrosion mitigation protocols are employed to slow the corrosion process to an acceptable rate for the application. When to use corrosion mitigation systems, and which system, depends on the corrosivity of the soils in which the pipeline is buried. The Bureau of Reclamation's specification for DIP in highly corrosive soil has been contested by some as an overly stringent requirement, necessitating the pipe to be modified from its as-manufactured state and thereby adding unnecessary cost to a pipeline system. This book evaluates the specifications in question and presents findings and recommendations. Specifically, the authoring committee answers the following questions: Does polyethylene encasement with cathodic protection work on ductile iron pipe installed in highly corrosive soils? Will polyethylene encasement and cathodic protection reliably provide a minimum service life of 50 years? What possible alternative corrosion mitigation methods for DIP would provide a service life of 50 years?
Review of the Federal Strategy for Nanotechnology-Related Environmental, Health, and Safety Research
by National Research Council of the National AcademiesThis 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.
Review of the National Defense Intelligence College's Master's Degree in Science and Technology Intelligence
by Committee for the Review of the Master's Degree Program for Science Technology Intelligence ProfessionalsThe National Research Council (NRC) was asked by the National Defense Intelligence College (NDIC) to convene a committee to review the curriculum and syllabi for their proposed master of science degree in science and technology intelligence. The NRC was asked to review the material provided by the NDIC and offer advice and recommendations regarding the program's structure and goals of the Master of Science and Technology Intelligence (MS&TI) program. The Committee for the Review of the Master's Degree Program for Science and Technology Professionals convened in May 2011, received extensive briefings and material from the NDIC faculty and administrators, and commenced a detailed review of the material. This letter report contains the findings and recommendations of the committee. "Review of the National Defense Intelligence College's Master's Degree in Science and Technology Intelligence" centers on two general areas. First, the committee found that the biological sciences and systems engineering were underrepresented in the existing program structure. Secondly, the committee recommends that the NDIC faculty restructure the program and course learning objectives to focus more specifically on science and technology, with particular emphasis on the empirical measurement of student achievement. Given the dynamic and ever-changing nature of science and technology, the syllabi should continue to evolve as change occurs.
