When Jørn Utzon resigned from the uncompleted Sydney Opera House project in February 1966, his successor Peter Hall was faced with innumerable and inevitably controversial design problems. But one of Hall's greatest dilemmas was not design-related. With Utzon signalling a wish to return to the job in early 1967, Hall found himself entangled in negotiations to pressure the government to reconcile with the original architect. Identified by the self-appointed conciliation strategist, Sydney academic Dr Philip Parsons, as the key intermediary by which negotiations succeeded or failed, Hall was torn between his professional regard for Utzon's claim to the building, doubts over Utzon's professed spirit of compromise and the contradictory advice of colleagues and government officials. Drawing on newly discovered documentation in Parsons' papers, this article explores the ambiguity of allegiances with which Hall was faced during 1967, Utzon's vacillating overtures and the well-intentioned dedication with which Parsons sought to affect a viable reconciliation. A little-known sequel to the muchpublished 1966 resignation story, the complex interweaving of Utzon's apparently changed attitude in 1967, Hall's divided loyalties and the government's continuing intransigence contribute new layers to the Opera House narrative.

ISBN 978-0-19-957322-6.Researchers have cited the lack of autecological knowledge as a barrier to predicting the impact of future climate change on freshwater biota. Aquatic Entomology goes a long way towards closing this knowledge gap, providing an in-depth examination of the morphological and physiological features that allow aquatic insects to survive in their environment.The book is divided into five parts, each comprised of chapters developing the theme of the previous section and becoming increasingly complex. Part 1 is an introduction to aquatic insects. It begins with an in-depth examination of insect body structure and a description of the main features of each aquatic order. This is well illustrated with line drawings and grey-tone photos, and most terminology is explained. However, readers without a good basic knowledge of insect morphology may find some sections difficult to understand. A glossary of terms or a labelled diagram of a generic insect body plan would have made this section more user friendly. The second chapter looks at the evolution and distribution of aquatic insects and includes a summary of evidence supplied by the fossil record. This chapter also gives a short introduction to the types of habitats inhabited by aquatic insects.Part 2 contains three chapters that cover the environmental constraints on insect distribution and give a detailed explanation of insect physiology, including the strategies that allow terrestrial insects to survive in an aquatic environment. This includes the physical problems of gas exchange and the most common physiological and behavioural adaptations that insects use to overcome these problems. Each concept is well illustrated, and readers are directed to sources of further information on complex topics. One chapter looks at physicochemical factors and the response of aquatic insects to heat, cold, desiccation and the problem of osmoregulation. Another covers the physical properties of water, including the effects of resistance and drag, shear stress and boundary layers on different aquatic body shapes. This is followed by the biomechanics of living in and on water and the physical adaptations of aquatic insects to those conditions. Part 3 goes into further detail of sensory systems, insect movement in and around water and the mechanics of dispersal to new habitats. This section provides minute detail on the structure and function of simple and compound eyes and their sensitivity and ability to detect shapes and colours. This theme expands on chemical and mechanical sensory systems, the use of setae and antennae and cuticular sense receptors. This chapter also includes the use of mechanical signalling, stridulation, vibration and percussion, chemical receptors and communication via chemical cues. Locomotion and buoyancy, insect limb structure, and the constraints and adaptations to moving in and on water and on different types of substrates are considered in t...
