An international survey of shock and vibration technology

This report is a very broad survey of a technology from an international viewpoint. There was no attempt to cover any subject within the technology in great depth. This would be impractical in a report of this scope, since each subject area in the shock and vibration field could well be the topic for a treatise all its own. The many references cited were for the purpose of indicating trends, and, perhaps, to offer some direction to those interested in specific areas covered in this report.

Propeller blade vibration flight and ground testing required special

Designing multi-media to train the thermal signatures of vehicles

Guidelines for using multi-media technology to train the thermal signatures of combat vehicles were developed from training effectiveness experiments with a prototype multi-media program and the instructional design literature. The guidelines specify requirements for a database of thermal images. The database must be constructed to support vehicle recognition and identification exercises as well as in basic instruction on thermal technology and on thermal cues. Factors to consider in developing vehicle recognition exercises are presented, to include the exercise format, establishment of vehicle sets, selection of part-task training schedules, and the type of feedback needed for soldiers and instructors. How to generate training strategies that adapt to the skill level of the soldier is described. Flexibility in the instructional design is stressed as the primary means of meeting the varied training requirements within the military. The need for an instructor's guide describing how to maximize the training features in a flexible training program is emphasized. The guidelines were applied to a multi- media, thermal training program developed in conjunction with the Night Vision and Electronic Sensors Directorate and the Product Manager for Forward Looking Infrared.

In designing these components, software developers must be mindful of the

Hearing Loss Research at NIOSH:

Reviews of Research Programs of the National Institute for Occupational Safety and Health

The National Institute for Occupational Safety and Health (NIOSH) was established by the Occupational Safety and Health Act of 1970 (U.S. Congress, 1970). Today the agency is part of the Centers for Disease Control and Prevention of the U.S. Department of Health and Human Services. NIOSH is charged with the responsibility to "conduct . . . research, experiments, and demonstrations relating to occupational safety and health" and to develop "innovative methods, techniques, and approaches for dealing with [those] problems" (U.S. Congress, 1970). Its research targets include identifying criteria for use in setting worker exposure standards and exploring new problems that may arise in the workplace. Prevention of occupational hearing loss has been part of the NIOSH research portfolio from the time the agency was established. A principal cause of occupational hearing loss is the cumulative effect of years of exposure to hazardous noise. Exposure to certain chemicals with or without concomitant noise exposure may also contribute to occupational hearing loss. Hearing loss may impede communication in the workplace and contribute to safety hazards. Occupationally acquired hearing loss may also have an adverse effect on workers' lives beyond the workplace. No medical means are currently available to prevent or reverse it, although hearing aids are widely used and research on other treatments is ongoing. Occupational hearing loss is a serious concern, although the number of workers affected is uncertain. In September 2004, NIOSH requested that the National Academies conduct reviews of as many as 15 NIOSH programs with respect to the impact and relevance of their work in reducing workplace injury and illness and to identify future directions that their work might take. The Hearing Loss Research Program was selected by NIOSH as one of the first two programs to be reviewed. Hearing Loss Research at NIOSH examines the following issues for the Hearing Loss Research Program: (1) Progress in reducing workplace illness and injuries through occupational safety and health research, assessed on the basis of an analysis of relevant data about workplace illnesses and injuries and an evaluation of the effect that NIOSH research has had in reducing illness and injuries, (2) Progress in targeting new research to the areas of occupational safety and health most relevant to future improvements in workplace protection, and (3) Significant emerging research areas that appear especially important in terms of their relevance to the mission of NIOSH.

Survey Automation

Report and Workshop Proceedings

For over 100 years, the evolution of modern survey methodologyâ€"using the theory of representative sampling to make interferences from a part of the population to the wholeâ€"has been paralleled by a drive toward automation, harnessing technology and computerization to make parts of the survey process easier, faster, and better. The availability of portable computers in the late 1980s ushered in computer-assisted personal interviewing (CAPI), in which interviewers administer a survey instrument to respondents using a computerized version of the questionnaire on a portable laptop computer. Computer assisted interviewing (CAI) methods have proven to be extremely useful and beneficial in survey administration. However, the practical problems encountered in documentation and testing CAI instruments suggest that this is an opportune time to reexamine not only the process of developing CAI instruments but also the future directions of survey automation writ large.

Testing of Defense Systems in an Evolutionary Acquisition Environment

The Department of Defense (DoD) recently adopted evolutionary acquisition, a dynamic strategy for the development and acquisition of its defense systems. Evolutionary defense systems are planned, in advance, to be developed through several stages in a single procurement program. Each stage is planned to produce a viable system which could be fielded. The system requirements for each stage of development may be specified in advance of a given stage or may be decided at the outset of that stage's development. Due to the different stages that comprise an evolutionary system, there exists a need for careful reexamination of current testing and evaluation policies and processes, which were designed for single-stage developments. The Office of the Under Secretary of Defense for Acquisition, Technology and Logistics (USD-AT&L) and the Director of Operational Testing and Evaluation (DOT&E) asked the Committee on National Statistics (CNSTAT) of the National Academies to examine the key issues and implications for defense testing from the introduction of evolutionary acquisition. The CNSTAT was charged with planning and conducting a workshop to study test strategies for the evolutionary acquisition. The committee reviewed defense materials defining evolutionary acquisition and interviewed test officials from the three major test service agencies to understand the current approaches used in testing systems procured through evolutionary acquisition. The committee also examined possible alternatives to identify problems in implementation. At the workshop that took place on December 13-14, 2004, the committee tried to answer many questions including: What are the appropriate roles and objectives for testing in an evolutionary environment?, Can a systematic, disciplined process be developed for testing and evaluation in such a fluid and flexible environment?, and Is there adequate technical expertise within the acquisition community to fully exploit data gathered from previous stages to effectively combine information from various sources for test design and analysis?. Testing of Defense Systems in an Evolutionary Acquisition Environment provides the conclusions and recommendations of the CNSTAT following the workshop and its other investigations.
