Three families are reported who have a translocation involving 4p16.3. Nine subjects are described with the clinical features of the Pitt-Rogers-Danks (PRD) syndrome confirming pre- and postnatal growth failure, microcephaly, severe mental retardation, seizures, and a distinctive facial appearance; a deletion of 4p16.3 was seen in all eight patients studied with fluorescence in situ hybridisati...

Our thinking in this area has been influenced by the developments in therapeutic thinking in general, but particularly by the evolution of client-centered therapy. The client-centered orientation was, at first, characterized by a rather specific technique or method: the therapist consistently responded by “reflecting” the client’s feeling. This meant that the therapist avoided diagnosis and ded...

We reexamine Rogers’ (1994) analysis of the biological basis of the rate of time preference. Although his basic insight concerning the derivation of the felicity function holds up, the functional form he uses does not generate the evolutionary equilibrium behavior. Moreover, Rogers relies upon an interior solution for a particular kind of intergenerational transfer. We show such interior soluti...

Recently, starting from two infinite summation formulae for Hall-Littlewood polynomials, two of the present authors [7] have generalized a method due to Macdonald [9] to obtain new finite summation formulae for these polynomials. This approach permits them to extend Stembridge’s list of multiple qseries identities of Rogers-Ramanujan type [12]. Conversely these symmetric functions identities ca...

The impact of import competition on labour productivity is examined using panel data for a sample of Australian manufacturing firms over the period 1984 to 1993. Import competition is found to interact with domestic competition; such the positive impact of import competition on the level and rate of growth of labour productivity rises with the degree of concentration among domestic producers. T...

PURPOSE The purpose of this investigation was to examine the impact of Chromosome 4p- syndrome on the communication and expressive language phenotype of a large cross-cultural population of children, adolescents, and adults. METHOD A large-scale survey study was conducted and a descriptive research design was used to analyze quantitative and qualitative data regarding the communication and ex...
