A comparative study of family therapy in the treatment of opiate users in a London drug clinic

This study presents the results of a randomized treatment trial of family therapy and two control treatments for 119 outpatient opiate users. All treatments were combined with a methadone reduction programme. The control treatments were: (1) a 'standard' treatment (supportive psychotherapy) and (2) a 'low contact' intervention. Treatment outcome was evaluated six and twelve months after the initial assessment. Both the family therapy and minimal intervention groups had a significantly higher number of drug–free days at six and twelve months, compared to the standard treatment, despite receiving fewer treatment sessions. Across all treatments there was evidence for a gender difference in response to therapy in users who were in a couple relationship. In couples where both partners were using drugs women did significantly better than men. Men living with a non–drug–abusing partner fared better than men living with a drug–using partner. Across the treatment groups diminution in drug use was accompanied by improvements in psychosocial functioning. Unemployment, sharing needles and injecting drugs were predictive of poor outcome.     

Tackling Three Of Frege's Problems: Edmund Husserl on Sets and Manifolds

Edmund Husserl was one of the very first to experience the directimpact of challenging problems in set theory and his phenomenology first began to takeshape while he was struggling to solve such problems. Here I study three difficultiesassociated with Frege's use of sets that Husserl explicitly addressed: reference to non-existent, impossible, imaginary objects; the introduction of extensions; and ``Russell's' paradox.I do so within the context of Husserl's struggle to overcome the shortcomings of set theory andto develop his own theory of manifolds. I define certain issues involved and discuss howHusserl's theory of manifolds might confront them. In so doing I hope to help bring Husserl'stheories about sets and manifolds out of the realm of abstract theorizing and promptfurther exploration of uncharted philosophical territory rich in philosophical implications.     

Kantian Themes in Contemporary Philosophy: Graham Bird

Michael Friedman criticises some recent accounts of Kant which 'detach' his transcendental principles from the sciences, and do so in order to evade naturalism. I argue that Friedman's rejection of that 'detachment' is ambiguous. In its strong form, which I claim Kant rejects, the principles of Euclidean geometry and Newtonian physics are represented as transcendental principles. In its weak form, which I believe Kant accepts, it treats those latter principles as higher order conditions of the possibility of both science and ordinary experience. I argue also that the appeal to naturalism is unhelpful because that doctrine is seriously unclear, and because the accounts Friedman criticises are open to objections independent of any appeal to naturalism.     

The effects of externalization on syllogistic reasoning

An experiment is reported that investigated the effects of externalization of mental models in syllogistic reasoning. Although there was no evidence that the requirement to “externalize” mental models of syllogisms improved reasoning, an unexpected recognition test demonstrated that subjects' memory for the meaning of the premises was improved by externalization. In particular, where the correct conclusion had been deduced using the externalization procedure, responses in the recognition test reflected an appreciation of the relations between the end terms of the premises.
