The mechanisms responsible for the fine tuning of development, where the wildtype phenotype is reproduced with high fidelity, are not well understood. The difficulty in approaching this problem is the identification of mutant phenotypes indicative of a defect in these fine‐tuning control mechanisms. Evolutionary biologists have used asymmetry as a measure of developmental homeostasis. The rationale for this was that, since the same genome controls the development of the left and right sides of a bilaterally symmetrical organism, departures from symmetry (...) can be used to measure genetic or environmental perturbations. This paper examines the relationship between asymmtry and resistance to organophosphorous insecticides in the Australian sheep blowfly, Lucilia cuprina. A resistance gene, Rop‐1, which encodes a carboxylesterase enzyme, also confers a significant increase in asymmetry. Continued exposure of resistant populations to insecticide has selected a dominant suppressor of the asymmetry phenotype. Genetic evidence indicates that the modifier is the L. cuprina Notch homologue. (shrink)

First published in 1999. Routledge is an imprint of Taylor & Francis, an informa company.

Originally published in 1940, this is a contribution to the better understanding of Evangelical experience and doctrine. It is the author’s belief that the application of psychology to religion in general can make little or no further advance except through the study of particular types of religious experience. The various psychotherapeutic techniques provide the means for such a study, and in this volume they are applied to Evangelicalism. At first the author attempts to justify this application to Evangelical experience and (...) doctrine, and outlines what he believes to be the essence of Evangelicalism. Part 2 of the book begins the contribution proper with an attempt to get a clear view of conscience and proceeds to salvation and its problems: conversion, guilt, sin, forgiveness, atonement. Part 3 deals with Evangelical experience and doctrine and the spiritual life of the Evangelical, and concludes with some general applications of psychology to Church work. (shrink)
