    This paper reviews some of the proposals for arms control which have been in the past. It is shown that although some progress has been made in indicating means for reducing the effects of some of the peripheral causes of war, no plausible solution has yet been discovered for the central problem. Even the definition of the objectives which should be set for an arms control process is obscure. A brief review of the statistical incidence of war by magnitude and severity indicates that the trend to large wars of increasing severity has existed for almost a hundred years, culminating in the availability of nuclear weapons. A recognition of the possible consequences of this trend, intensified by the knowledge of the capabilities of nuclear weapons, has produced the current growing effort to understand the problem and to find acceptable arms controls.

    Short-wavelength illuminants of a blue color are used in lighting SAGE and other military operations rooms in which dim cathode-ray tubes are the primary visual source of information. This study investigated the effect of such lighting on the operator's visual acuity in the performance of secondary visual tasks. View full abstract»

    The rms-error performance of a human operator in a simple closed-loop control system responding to input signals from a non-Gaussian process was measured and compared with the performance of an ``optimum'' linear controller. The results show that the human operator produces rms errors which are approximately equal to those produced by a highly constrained optimum linear controller. Comparison of the error-signal waveforms in the human operator system and the linear system reveals some adaptive behavior on the part of the human operator. View full abstract»

  • Relative Frequency Analysis to Assess Communication Feedback in a Malfunction-Coding Scheme

    Samples of data generated by the coding scheme now being used by the military to collect statistics on equipment malfunction were analyzed by psycholinguistic means. Frequency-to-rank distributions plotted on logarithmic coordinates were compared with Zipf's generalization and were found to be markedly aberrant. It is deemed likely that this reflects a lack of sufficient feedback from the users of malfunction data to those who report the data and to those who are responsible for the design of the coding scheme.

  • Decision Programming: A Model of Man-Machine Control

    A stochastic equation is used to generate a sequence of pointer positions on a voltmeter dial. The successive positions are characterized by a ``drift'' parameter and a ``noise'' parameter. The voltmeter dial also shows a pair of symmetrical tolerances. A subject and a machine share the task of maintaining the pointer within the tolerances. The task is accomplished by repetitively asking and answering three questions: 1) Is the pointer now within the specified tolerances?, 2) If not, what corrective action is appropriate?, and 3) Was the preceding corrective action effective in maintaining control over the pointer?
