First-Order Frege Theory is Undecidable

The system whose only predicate is identity, whose only nonlogical vocabulary is the abstraction operator, and whose axioms are all first-order instances of Frege's Axiom V is shown to be undecidable.     

Applying Buddhist Practices to Recovery: What I Learned From Skiing With a Little Buddha Wisdom

The author describes how 5 Buddhist practices—enlightenment, compassion, acceptance, mindfulness/meditation, and the spiritual community—can serve as a foundation for an integrated recovery model that incorporates numerous perspectives from the 12‐step program of Alcoholics Anonymous. An application of the model illustrates how it is applied to real‐life recovery.     

The six most essential questions in psychiatric diagnosis: a pluralogue. Part 4: general conclusion

In the conclusion to this multi-part article I first review the discussions carried out around the six essential questions in psychiatric diagnosis – the position taken by Allen Frances on each question, the commentaries on the respective question along with Frances’ responses to the commentaries, and my own view of the multiple discussions. In this review I emphasize that the core question is the first – what is the nature of psychiatric illness – and that in some manner all further questions follow from the first. Following this review I attempt to move the discussion forward, addressing the first question from the perspectives of natural kind analysis and complexity analysis. This reflection leads toward a view of psychiatric disorders – and future nosologies – as far more complex and uncertain than we have imagined.     

The six most essential questions in psychiatric diagnosis: a pluralogue part 3: issues of utility and alternative approaches in psychiatric diagnosis

In face of the multiple controversies surrounding the DSM process in general and the development of DSM-5 in particular, we have organized a discussion around what we consider six essential questions in further work on the DSM. The six questions involve: 1) the nature of a mental disorder; 2) the definition of mental disorder; 3) the issue of whether, in the current state of psychiatric science, DSM-5 should assume a cautious, conservative posture or an assertive, transformative posture; 4) the role of pragmatic considerations in the construction of DSM-5; 5) the issue of utility of the DSM ?C whether DSM-III and IV have been designed more for clinicians or researchers, and how this conflict should be dealt with in the new manual; and 6) the possibility and advisability, given all the problems with DSM-III and IV, of designing a different diagnostic system. Part 1 of this article took up the first two questions. Part 2 took up the second two questions. Part 3 now deals with Questions 5 & 6. Question 5 confronts the issue of utility, whether the manual design of DSM-III and IV favors clinicians or researchers, and what that means for DSM-5. Our final question, Question 6, takes up a concluding issue, whether the acknowledged problems with the earlier DSMs warrants a significant overhaul of DSM-5 and future manuals. As in Parts 1 & 2 of this article, the general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.     

Type A Personality Characteristics and the Effect on Individual and Team Academic Performance

Type A personality has been conceptualized in part as high need for achievement combined with aggression, hostility, and self-esteem issues. In teams of undergraduate business students, high levels of Type A personality significantly correlated with high levels of depression and high levels of social monitoring; and negatively correlated with social desirability, communality, and individual performance across time. In team settings, the more Type A's were balanced in a team with low Type A's, the more there was team commitment and the more team synergy behaviors; while if teams had a greater number of Type A's, there was more individualistic behavior, and team project scores were lower.
