Developing expert systems for management applications

The Alvey Report has resulted in a growing interest in the UK in ‘expert systems’. It is fairly generally accepted, at least in the UK, that such systems function in a particular type of way, i.e. they arrive at decisions through a process of rule based inference. It is suggested that it may be more fruitful to regard rule based inference as one approach to the construction of expert systems, and that proven techniques of operational research may well be more useful in constructing other types of expert system. Alternative applications of expert systems are derived on the basis of a broader definition of an expert system in terms of what it does rather than how it does it. A parallel is drawn between these applications and some typical concerns of business research. It is suggested that a useful aid in identifying promising business applications of expert systems is to set up four ‘dimensions’ along which different types of system differ. Examples are given of where other techniques might conceivably be useful in applications of expert systems.     

The simulation of industrial robot systems

This paper describes the GRASP computer aided design system for modelling and evaluating industrial robot workplaces. GRASP satisfies a range of simulation needs within the context of designing, implementing and operating industrial robotic systems. The GRASP software may be used to investigate robots operating by themselves or, more likely, as part of an integrated cell. Facilities within GRASP assist workplace layout, position and velocity evaluations, clash detection and co-ordination between items. A robot library exists and is being extended, and an embryo off-line programming facility has been used under restricted conditions. GRASP has been used to help solve a wide range of practical industrial robot problems and has proved itself technically, and also as an educational tool, by showing how a proposed system would operate. The paper describes the facilities within GRASP.     

语篇翻译中的英汉衔接手段对比——布什9．11演讲分析

Sample Entropy Statistics and Testing for Order in Complex Physiological Signals

Sample Entropy (SampEn) statistics have provided insight into the amount of order present in several types of complex physiological time series, particularly the heart rate dynamics of premature infants. Very little, however, is known of SampEn's statistical properties and this has hindered strategies for optimization and significance testing. This article shows that SampEn statistics are asymptotically Gaussian under general conditions. A straightforward point estimate of the statistic's variance is developed and compared to empirical results obtained from complex surrogate data. Statistical tests are developed to quantify the amount and scale of order detected in a signal. These tests are used to show that significant order is, in fact, being detected in the heart rate dynamics of neonates, and to suggest strategies for optimizing the analysis parameters.     

The Philippine Male Aging Survey

The aging male is fast becoming a global concern. The problem is predicted to become a major health issue that should be addressed immediately in order to prevent disability, morbidity, and, more importantly, mortality. As part of its commitment to increase awareness and create interest in the care of Filipino aging males, The Philippine Society for the Study of the Aging Male Foundation, Inc. (PhiSSAM), a multi-specialty society established in 2000, embarked on a survey among Filipino physicians to determine their knowledge, attitudes, and practices regarding male aging. Results showed that the majority of doctors (about 87%) thought that men may experience andropause. Most would diagnose patients based on symptoms alone, while only 20–30% used testosterone levels to make a diagnosis of andropause. Decreased libido and less strong erections were the symptoms very closely associated with low testosterone. Of those doctors responding, 89% agreed that andropause can affect the quality of a man's life as much as menopause can affect a female; only 38% had already prescribed/instituted treatment for andropause. Of the 62% non-prescribers, 58% said they were either very likely or fairly likely to institute treatment in the future if there were more clinical trials, more medical information, and more information on drugs. Major concerns on testosterone replacement therapy included prostate cancer, benign prostatic hypertrophy, and heart disease. The findings in this pilot survey indicate a need among the doctors in the Philippines for education about andropause and the available treatments.     

Sense of School Coherence, Perceptions of Danger at School, and Teacher Support Among Youth at Risk of School Failure

Using a sample of middle and high school students who had been identified by school personnel as at risk of school failure, this investigation examines two competing models about the effects of students' perceptions of danger at school and teacher support on their sense of school coherence. From the compensatory model, it is assumed that risk and protective factors combine additively to influence outcomes. From the immunity model, it is assumed that protective factors buffer or moderate the negative effects of risk factors on outcomes. Support is found for the compensatory or additive model, with perceptions of school danger negatively influencing students' sense of school coherence and teacher support positively influencing variation in the criterion variable. Implications for theory, practice, and further research are discussed.

The Group Treatment of Bulimia

Abstract

The incidence of bulimia in college populations is increasing, but an understanding of the syndrome remains sketchy. The authors describe an approach of group psychotherapeutic treatment that has evolved over four years and offer a theoretical formulation of the psychodynamics that may underlie the development of bulimia.
