Relations amongm sets of measures

The problem of determining linear functions for two sets of variables so as to maximize the correlation between the two functions has been solved by Hotelling. This article presents a more efficient computational solution for the case of two sets of variables and a generalized solution for any number of sets. Applications are discussed and a numerical example is included to demonstrate the solution for more than two sets.     

Optimal test length for multiple prediction: The general case

The concepts of differential prediction and multiple absolute prediction were developed in earlier papers [2, 3]. Methods for determining optimal distribution of testing time for each type of prediction are available [4, 5] and are appropriate for use provided that no altered time allotment approaches zero. In this article the methods developed in [4, 5] are extended to include cases where the altered time allotment for one or more tests may approach zero. The procedures developed are illustrated by numerical examples, after which the mathematical rationales are provided.     

The calculation of sums of squares for interactions in the analysis of variance

A method is described for the calculation of the sum of squares for a second-order interaction. It is then shown that the method is general and can be used for the calculation of the sum of squares for any higher-order interaction.     

Stimulating the demand for dental care: An application of Ajzen and Fishbein's theory of reasoned action

Ajzen and Fishbein's attitude-behaviour model was applied to the problem of stimulating the demand for dental care, Subjects were 329 members of Amsterdam health insurance companies. They had not received regular dental treatment and/or a certificate of dental fitness for at least two and a half years. Applying for treatment and acquiring a dental certificate were the behavioural measures. The effectiveness of the communication based on Ajzen and Fishbein's model was compared with the effectiveness of messages based on the Health-Belief model and the notion that knowledge of Rights and Obligations is a prerequisite for seeking dental care. Results lend support to the validity of the Ajzen and Fishbein model. Relationships between the components of the model are moderate to strong, both before and after subjects were exposed to the message. The message proved effective in changing beliefs about seeking dental treatment. Ajzen and Fishbein's claim that their approach has exclusive merits, however, was refuted. A differential effectiveness of the three messages was absent. In all, 47.4 per cent applied for treatment. No control subjects applied. Fifteen months later 70 per cent of the applicants had obtained a dental certificate. Contrary to our expectations, a condition of no-message application-form- only proved equally effective as the message conditions.     

Psychosoziale Belastungen von Bahnpendlern

The increasing number of commuters in our society raises the question of the consequences, in particular of psychiatric and somatic symptoms and the quality of life. A total of 407 commuters at the main railway stations in Stuttgart and Ulm (southern Germany) were included in a study in order to assess the psychiatric symptoms of commuters and if they are able to make use of psychosocial care despite the long periods of time spent commuting to work. An important result was that especially long-term commuters pay a high price: 31.3% of male and 37.3% of female commuters exceeded the cut-off point for psychiatric illness in the Outcome Questionnaire (OQ-45.2). The high prevalence of psychiatric disorders coincides with a high rate of unmet needs so that a high rate of false and under-treatment for commuters can be assumed.     

DEWEY ON EXTENDED COGNITION AND EPISTEMOLOGY

There is a surge of attempts to draw out the epistemological consequences of views according to which cognition is deeply embedded, embodied and/or extended (e‐cog). The principal machinery used for doing so is that of analytic epistemology. Here I argue that Dewey's pragmatic epistemology may be better fit to the task. I start by pointing out the profound similarities between Dewey's view on cognition and that emerging from literature of more recent date. Crucially, the benefit of looking at Dewey is that Dewey, unlike contemporary writers, also devises a corresponding epistemology. I then identify two senses in which contemporary analytic epistemology conflicts with e‐cog—concluding from that the superiority of the Deweyian framework, at least as it concerns accommodating e‐cog.     

Adult Attachment Interview and Psychoanalytic Perspective: A Single Case Study

In this single case study we present a female patient diagnosed with a narcissistic personality disorder and a borderline organization. The interplay between attachment and psychoanalytic perspective will be focused. The analyst describes his impressions of the initial interview with the patient and essential steps during treatment. The patient was interviewed with the Adult Attachment Interview and classified as “insecure preoccupied” with an “unresolved state of mind” concerning loss and abuse. The analyst was asked to comment the AAI's essential characteristics of this patient. We discuss converging and diverging aspects of clinical and attachment interpretation in this single case.
