Between Abduction and the Deep Blue Sea

Stathis Psillos and James Ladyman et al. have recently joined battle over Bas van Fraassen's account of abduction and inference to the best explana-tion (IBE), and while van Fraassen makes many interesting criticisms, Psillos has had the best of the exchange. In part I of this paper I aim to extend Psillos' criticisms by suggesting that van Fraassen's critique of IBE is at odds, not only with The Scientific Image but also with his later work. Part II uses some of van Fraassen's ideas to suggest a third way between realist IBE and outright abductive scepticism.     

Brief Therapy in Adult Psychiatry – Further Outcomes

A report of a one-year follow-up of thirty-six referrals treated with solution-focused brief therapy by a supervised team in a mental health setting is described. A good outcome was reported for twenty-three cases (64%). These results are comparable with our previous work and with one other statistically validated outcome study on solution-focused therapy.     

Distributive lattices with a dual homomorphic operation

The lattices of the title generalize the concept of a De Morgan lattice. A representation in terms of ordered topological spaces is described. This topological duality is applied to describe homomorphisms, congruences, and subdirectly irreducible and free lattices in the category. In addition, certain equational subclasses are described in detail.     

Repeated assessment of cognition in children and the measurement of performance change.

There is limited understanding of the problems associated with repeated neuropsychological assessment in children, including the statistics used to guide decisions about cognitive change. This study investigated the utility of a computerized assessment battery that was specifically designed for the repeated assessment of cognitive function in children. Eighty-seven participants aged 8 to 12 years completed the battery four times within a 2-hour testing session. The results support the application of this assessment battery for measuring cognitive change in children. A novel method for calculating measurement error is employed, and its use in the detection of cognitive change in individual children is discussed. An estimate of the measurement error within each of the tests is provided, and recommendations are made regarding the application of this assessment battery for measuring cognitive change in children.     

Synonymous Logics

This paper discusses the general problem of translation functions between logics, given in axiomatic form, and in particular, the problem of determining when two such logics are synonymous or translationally equivalent. We discuss a proposed formal definition of translational equivalence, show why it is reasonable, and also discuss its relation to earlier definitions in the literature. We also give a simple criterion for showing that two modal logics are not translationally equivalent, and apply this to well-known examples. Some philosophical morals are drawn concerning the possibility of having two logical systems that are empirically distinct but are both translationally equivalent to a common logic.     

The Factor Structure of Anxiety and Depressive Disorders in a Sample of Clinic-Referred Adolescents

The current study used confirmatory factor analysis (CFA) to examine the factor structure of anxiety and depressive disorders in a sample of clinic-referred adolescents, aged between 12 and 18 years, for diagnoses based on parent (N?=?655; male?=?441) and adolescent (N?=?626; male?=?417) interviews. Three models were examined: a 1-factor model, with all anxiety and depressive disorders in a single factor; a DSM-based 2-factor model, with anxiety disorders in one factor, and depressive disorders in another factor; and an alternate 2-factor model, with fear related anxiety disorders in one factor, and other anxiety and depressive disorders in another factor. The findings indicated support for all three models. Also, ADHD and ODD/CD were associated with only the shared variances between the latent factors in the 2-factor models, and not their unique variance. The implications of the findings for taxonomy, comorbidity, and clinical practice are discussed.     

论德性与独立的实践推理者

德性对于人的兴盛是必不可少的。没有道德德性,我们就不能实现从动物性理智到实践推理的转变,其次不能继续有推理的实践;如果不发展某种程度的德性,我们就不能适当地关怀和教育他人。所以,德性必须首先获得,然后才能维持在推理的实践之中。最后,我们在成为实践推理之后,我们仍然需要他人的维护,这种需要同时也是一种对德性的需要。
