Effect of Prolonged Bedrest and  Gz Acceleration on Peripheral Visual Response Time

The cardiovascular deconditioning, dehydration, and other physiological changes that occur as a result of prolonged exposure to the zero g space environment raise some questions about the applicability of much previous research which has shown that spacecraft atmosphere reentry accelerations pose no appreciable physiological or performance problems for the astronauts. This report deals with whether or not peripheral visual response time changes during +Gz acceleration following fourteen days of bedrest as well as what effect prolonged bedrest has upon this response.

Analysis

V. 1. The relationship between police response time, outcomes of calls for police assistance, and citizen crime reporting is analyzed in a study performed in Kansas City, Missouri. This study was conceived and developed to test the assumption that responding quickly to calls for police service will produce the most desirable outcomes, and to identify those problems and patterns which might affect how quickly a citizen reports a need for police service. The design of the study and data collection spanned 3 years, although the primary data were collected during 1975, in Kansas City. Trained civilian observers accompanied officers into the field to collect data on travel times and on-scene activities, while tape analysts collected dispatch time data by timing telephone and radio exchanges recorded by the communications unit. Interviewers questioned victims of crimes and citizens who reported crime and noncrime incidents or requested police service. The calls for service making up the data base came primarily from a target area selected for its high rates of robberies and aggravated assaults. The data covered the entire spectrum of police service, including both Part I and Part II crime calls, potential and noncrime calls, and traffic accidents. An introduction to the project is provided, and the setting of the subject area and the search are described. The examination of the sample design and the data collection process is illustrated by tables. -- v. 2. The analysis and findings of a Kansas City, Missouri. Study of the relationship between police response time, outcomes of calls for police assistance, and citizens, crime reporting are presented. This research was initiated to evaluate assumptions regarding rapid police response as an effective operational strategy and to identify problems and patterns which account for citizen delays in reporting crimes to the police. To test these assumptions, response time was conceptualized as consisting of three intervals: citizen reporting, communication dispatching, and police travel time. Variations in these intervals were then analyzed to see how they affected the probability of making an on-scene arrest, contacting a witness on-scene, and how they affected recovery from injuries sustained during the commission of Part I crimes. Additionally, the problems citizens encounter when reporting crimes and the patterns or actions citizens follow prior to reporting were identified and analyzed for their effects on reporting delays. Relationships between citizens' social characteristics and both reporting time and problems and patterns were analyzed. To see if the length of response time affected citizen satisfaction, police response times were again analyzed, with other factors considered to be possible determinants of citizen satisfaction. These factors included citizens' social characteristics, how long citizens expected response to be, citizens' perceptions of how long the response actually took, and how important citizens thought response time was to the outcomes of the incident they reported or in which they were involved. Statistical analysis is presented regarding response time, arrest, the effects of patrol procedures on response times and crime outcomes, witness availability, citizen injury, problems and patterns in reporting, the process of reporting, and citizen satisfaction; statistical summaries of each of these subject areas are provided in individual appendixes. Results indicate that reporting time was longer than either the time taken to dispatch a call or the time taken to travel to a call, and nearly as long as the combined time taken to dispatch and travel to a call. Response time was found to be unrelated to the probability of making an arrest or locating a witness for the large proportion of Part I crimes that were discovered after the crime had occurred. For those crimes involving a victim or witness, reporting time was the strongest time determinant of arrest and witness availability. Travel time generally had a limited effect on these outcomes, though for some types of crime the influence was strong. Citizen satisfaction was more closely related to citizens' expectations and perceptions about response time than actual response time. Problems citizens encounter and patterns they follow in reporting crime were identified and were found to produce delay in contacting police. Voluntary actions by citizens explained more delay in reporting than did problems experienced by citizens in contacting the police.

Stimulus Response Compatibility

Stimulus-response compatibility refers to the finding that certain mappings of stimuli to responses produce faster and more accurate responding than do others. The present volume surveys compatibility research which falls into four broad categories: (a) mental representation and coding (b) neurophysiological mechanisms (c) motor performance (d) human factors applications. The major findings and models within each of the categories are summarized, and an integrated perspective is provided. The research indicates that compatibility effects reflect basic cognitive processes that bear on a range of issues in cognitive science and that have applied implications for human factors specialists.

Integrating Timing Considerations to Improve Testing Practices

Integrating Timing Considerations to Improve Testing Practices synthesizes a wealth of theory and research on time issues in assessment into actionable advice for test development, administration, and scoring. One of the major advantages of computer-based testing is the capability to passively record test-taking metadata—including how examinees use time and how time affects testing outcomes. This has opened many questions for testing administrators. Is there a trade-off between speed and accuracy in test taking? What considerations should influence equitable decisions about extended-time accommodations? How can test administrators use timing data to balance the costs and resulting validity of tests administered at commercial testing centers? In this comprehensive volume, experts in the field discuss the impact of timing considerations, constraints, and policies on valid score interpretations; administrative accommodations, test construction, and examinees’ experiences and behaviors; and how to implement the findings into practice. These 12 chapters provide invaluable resources for testing professionals to better understand the inextricable links between effective time allocation and the purposes of high-stakes testing.

Real Time Embedded Systems

From the Foreword: "...the presentation of real-time scheduling is probably the best in terms of clarity I have ever read in the professional literature. Easy to understand, which is important for busy professionals keen to acquire (or refresh) new knowledge without being bogged down in a convoluted narrative and an excessive detail overload. The authors managed to largely avoid theoretical-only presentation of the subject, which frequently affects books on operating systems. ... an indispensable [resource] to gain a thorough understanding of the real-time systems from the operating systems perspective, and to stay up to date with the recent trends and actual developments of the open-source real-time operating systems." —Richard Zurawski, ISA Group, San Francisco, California, USA Real-time embedded systems are integral to the global technological and social space, but references still rarely offer professionals the sufficient mix of theory and practical examples required to meet intensive economic, safety, and other demands on system development. Similarly, instructors have lacked a resource to help students fully understand the field. The information was out there, though often at the abstract level, fragmented and scattered throughout literature from different engineering disciplines and computing sciences. Accounting for readers’ varying practical needs and experience levels, Real Time Embedded Systems: Open-Source Operating Systems Perspective offers a holistic overview from the operating-systems perspective. It provides a long-awaited reference on real-time operating systems and their almost boundless application potential in the embedded system domain. Balancing the already abundant coverage of operating systems with the largely ignored real-time aspects, or "physicality," the authors analyze several realistic case studies to introduce vital theoretical material. They also discuss popular open-source operating systems—Linux and FreRTOS, in particular—to help embedded-system designers identify the benefits and weaknesses in deciding whether or not to adopt more traditional, less powerful, techniques for a project.
