Presenting a paper to any conference with the name ‘Keynes’ in the title, particularly to one sponsored by the Post Keynesian Study Group, is fraught with danger. For the exegitical debate about ‘what Keynes really meant’ is often carried out with as much fervour as the arguments between the Fathers of the early Church. Indeed, some of the latter material has a familiar sound. Origen, for examp...

Here is a collection of interesting problems in geometry. Solution of each problem requires only one non-trivial idea. The project is oriented to graduate students who want to learn fast simple tricks in geometry. For problem solvers. Easy problems are marked by “◦” and hard problems by “∗”. If the solution requires knowledge of some not quite standard theorem it is marked by “+”, in this case ...

Given that religious faith is constitutionally procluded as a census question, it can be challenging to document the geography of religion at the micro level. This paper explores the geography of adherence to Orthodox Judaism in Brooklyn, New York through a variety of signature locational phenomena associated with the faith, including synagogues, yeshivas and kosher food retailers. The address,...

A large number of children present to paediatricians with psychological problems caused by the ordinary viscissitudes of development and of modern day family life, with its high rate of family breakdown and divorce. The paediatrician needs ways of intervening that can unlock or undo hold ups in successful treatment and ensure that the patient with abdominal pain, food refusal, or constipation d...

In response to "Prediction ofAcademic and Clinical Performance of Occupational Therapy Students in an EntryLevel Master's Program" (AjOT, October 1997), I have criticism of the methodology. The use of the Graduate Record Exam (GRE) as a measure of potential performance in an en ny-level master's program is flawed by the velY nature of such a program. By definition, an enny-Ievel master's progra...

BACKGROUND Although childhood vaccination programmes have been very successful, there are some hard to reach minority groups that object to vaccination. The Netherlands has experienced several epidemics of vaccine-preventable diseases, confined to the orthodox Protestant minority. However, vaccination coverage in this minority is still unknown and this hampers prevention and control of epidemic...

It has been well known that the band of idempotents of a naturally ordered orthodox semigroup satisfying the “strong Dubreil-Jacotin condition” forms a normal band. In the literature, the naturally ordered orthodox semigroups satisfying the strong Dubreil-Jacotin condition were first considered by Blyth and Almeida Santos in 1992. Based on the name “epigroup” in the paper of Blyth and Almeida S...

“Pro-existence” is a concept developed by 20th century western Christian theologians to describe the service of the Church facing contemporary challenges. The leading Romanian theologian Dumitru Staniloae (1903–1993) took this further by expressing his Orthodox understanding of the relationship between service and pro-existence. The article explores Staniloae’s call for Orthodox Christians to s...

Using a hierarchical-systems analysis, this paper supports the orthodox view of the mind. We claim that the orthodox mind – bounded by brains or bodies – is organized into various system levels, each of which is emergent from the dynamics of level below it. We see the extended mind hypothesis as borrowing terms from a high-level system of the orthodox mind and applying it to interactions betwee...

We introduce the notions of a generalised category and of an inductive generalised category over a band. Our purpose is to describe a class of semigroups which we name weakly B-orthodox. In doing so we produce a new approach to characterising orthodox semigroups, by using inductive generalised groupoids. Here B denotes a band of idempotents; we note that if B is a semilattice then a weakly B-or...
