ICI plc is convinced that there is a very real role for the end‐user in the acquisition of information by online search and Mond Division has been training end‐users since 1983. This article describes the setting‐up of the project, the methodology and results, and outlines developments being pursued in conjunction with other Divisions of ICI towards an ideal system. Implications of the project for the role of the information scientists themselves are considered.

The purpose of this paper is to test the attenuated-anger and heightened-anger hypotheses of psychopathy by assessing the physiological, behavioral, and subjective measures of anger in individuals with and without psychopathic traits.

In all, 62 male college students were assigned to one of three groups based on evidence of elevated affective-interpersonal (Factor 1) and antisocial lifestyle (Factor 2) traits associated with psychopathy (the IF1+F2 group), evidence of only Factor 2 traits (the F2 only group), or based on the absence of psychopathic traits (the control group), using Gough’s (1957) Socialization scale and a modified, interview only form of Hare’s (1991) Psychopathy Checklist-Revised. To induce anger, participants received unjust criticism about their performance on a computer-based affective lexical decision task and were denied a performance bonus they had reason to expect.

Following provocation, the three groups displayed similar increases in blood pressure, pulse, and self-reported anger. The control and IF1+F2 groups also displayed similar retaliation toward the confederate. However, the IF1+F2 group displayed smaller increases on two of three measures of facial muscle activity associated with anger.

This study is one of the first to assess anger responsiveness in individuals with psychopathic traits using a powerful anger induction and using physiological, behavioral, and subjective indices of anger. It is also the first to assess both the attenuated-anger and the heightened-anger hypotheses of psychopathy. The findings appear largely inconsistent with both perspectives.

THE following is a brief account of how Monospar machines are being made, rather than a description of a completely worked‐out production system, and also of the considerations which were borne in mind while the machine was being designed. These considerations can be grouped under three headings: Design, Production and Maintenance, and will be dealt with after a brief description of the whole machine, which may be of assistance in visualising how the components to be described are combined.

Discusses the model of industrial development, the S‐curve model and the model of technological life cycles. Shows that these three models are based on similar assumptions and are, therefore, closely related. The analysis shows, furthermore, that the models have significant implications for technology management. Finally, analyses the extent to which conventional methods of evaluating technological projects take these implications into account. Subjective evaluation techniques, risk/return analyses as well as portfolio methods are subject to critical appraisal. All in all, it becomes clear that these evaluative tools are, at best, of limited use.
