Determination of human error patterns: The use of published results of official enquiries into system failures

Official enquiries into large scale system failures may be used to interpret events according to the various types of human error which were committed. For example there are errors in operation of the system, in maintenance practices etc. Twelve well documented disasters are analysed and the conclusion emerges that operator error predominates. This fact is not suprising, reflecting as it does the short time span in which operators have to make decisions, compared to the other players such as designers, maintenance men etc. This conclusion has implications for the other human disciplines involved. For example designers should conceive systems which will be less prone to operator error, while management should support operators in whatever way possible to increase their effectiveness.

The relationship between attentional blink and psychological refractory period.

This study examined the relationship between attentional blink (AB) and psychological refractory period (PRP) using a conventional AB procedure combined with a requirement of speeded responses to the second target (T2). Experiments 1 and 2 showed that, as with PRP, memory retrieval of targets is not a necessary condition for the occurrence of AB in terms of accuracy and that AB occurred in the speed data. Experiment 3 further indicated that the PRP-like speed data were not due to the first target serving as a warning signal that triggered preparation of responses to T2. Experiment 4 manipulated T2 stimulus intensity to be normal or low. Results showed an underadditive interaction between stimulus intensity and lag position in the speed data, whereas an overadditive interaction was found in the accuracy data, suggesting 2 sources of interference leading to AB: the single-channel bottleneck and resource-limited visual-processing capacity.

The design of a user friendly engineering economy analysis package for a microcomputer

The design and features of a user friendly engineering economy analysis software package for the Apple II microcomputer is described. The software package is written in Applesoft Basic. An Apple II with 64k RAM, one or two disk drives and a line printer is required to use the software package. The package consists of five complementary programs: (1) Selection of the better of two alternatives using present-worth evaluations. (2) Conventional rate-of-return computations for a single project. (3) Selection from mutually exclusive alternatives using rate-of-return analysis. (4) Optimal capital allocation among several investment opportunities under risk. (5) Probabilistic after-tax economic analysis for a single project. All programs but (4) are based on the time value of money. Program (4) is a chance-constrained optimization model utilizing the Lagrange-multiplier technique. Program (5) implements depreciation, debt/equity financing, and taxes and performs a sequential after-tax Monte Carlo simulation over a specified life-span. The use of this software package does not require any previous computer or programming experience. A menu format is used. The software package allows the user to specify the shapes of the interest and inflation probability distributions on a year by year basis. The user has the option to specify the reinvestment rates. The package presents the results in tables and graphs. User acceptance has been excellent with this software package and this package is well suited for the use in an engineering economy class or for the practicing industrial engineer in industry.     

Review of The elderly in rural society: Every fourth elder.

Reviews the book, The elderly in rural society: Every fourth elder edited by Raymond T. Coward and Gary R. Lee (1985). Until recently, the gerontological literature has had a decidedly urban bias. This book is an important effort to fill the knowledge gap concerning the rural elderly and is a useful reference for students, academicians, service providers, and policy makers who share a concern for America's rural elderly. For many of the more than 59.5 million rural residents of this country, the romanticized vision of a tranquil and prosperous rural lifestyle has been replaced by the realities of economic deprivation, inadequate housing, and unaddressed physical and mental health problems. This book brings together a wealth of current information to understand these realities better. In addition to the editors, 16 distinguished contributors, primarily from the fields of sociology and social work, examine rural-urban differences and the implication of those differences for the rural elderly population. Chapters cover demographics, socioeconomic considerations, physical and mental health status, housing characteristics, family and community relationships, and the development and delivery of health and human services to the elderly in rural society. This book helps service providers to understand and be sensitive to the value system and social ecology of rural areas so that they can address real rather than assumed needs more effectively. Overall, the book is comprehensive and well-written and can serve as a resource for students and professionals from a variety of disciplines, including rehabilitation psychology, who may work with, live with, help, or study the rural elderly.
