Is There a Biochemical Predictor of Suicide?

ABSTRACT: There is a need for additional instruments to alert the clinician more effectively to the high self-destructive potential of some of his suicide-risk patients. In this study it was found that suicides-to-be tended to have higher plasma cortisols than suicidal patients who did not subsequently commit suicide within two years of the test. The article discusses the possible mechanisms involved and reviews some of the literature indicating that there may be a biochemical substratum that may play a significant role in some suicides.     

External thought—does sketching assist problem analysis?

An experimental study (n = 60 students) tests the advantages of being allowed to sketch a representation of a mechanical system (involving components such as weights, ropes and pulleys) when one is to be subsequently asked questions about this system. In comparison to a control group who were not allowed to sketch the system, the main advantages of sketching were found to be a reduction in the perceived difficulty of the problems and an increase in the likelihood of correctly inferring relations between the components. These advantages came at no extra cost in terms of additional time being needed to analyse the situation or solve the problems. However, sketching conferred no advantage in terms of the correct recall of system components. Copyright © 2004 John Wiley & Sons, Ltd.     

A multidimensional framework for financial–economic decisions

Most financial–economic decisions are made consciously, with a clear and constant drive to ‘good’, ‘better’ or even ‘optimal’ decisions. Nevertheless, many decisions in practice do not earn these qualifications, despite the availability of financial economic theory, decision sciences and ample resources. We plea for the development of a multidimensional framework to support financial economic decision processes. Our aim is to achieve a better integration of available theory and decision technologies. We sketch (a) what the framework should look like, (b) what elements of the framework already exist and which not, and (c) how the MCDA community can co‐operate in its development.

Cognitive Resources and Leadership Performance: What About the Task Requirements?

Fred E. Fiedler made an important contribution in summarising and discussing the tricky relationships between test-intelligence, time in service, and perceived experience on the one side, and rated leadership performance on the other. Two strings of results seem to be of importance for improving our knowledge on these relationships: (1) test-intelligence correlates with rated performance especially in the case of low perceived stress, and experience especially in the case of high stress; (2) test-intelligence correlates with rated performance if the other resource, perceived experience, is low. Both strings of results may fit with our expectations. Nevertheless, some aspects of the problem might trouble some readers, for reasons that Fiedler is not responsible for. There seem to be at least three clusters of unfulfilled wishes within this topic of research: selection and operationalisation of variables; design; and task requirements and intelligence.
