USING OPTICAL COHERENCE TOMOGRAPHY TO EXAMINE THE SUBSURFACE MORPHOLOGY OF CHINESE GLAZES

Optical coherence tomography (OCT), a new method for ceramics research, is a nondestructive, three‐dimensional tomography system, which provides subsurface morphology visualization of samples based on the refractive index or dielectric constant differences in the target specimen. In this study, seven shards from different Chinese kilns of Song and Yuan dynasties (10–14th centuries) were scanned to visualize the subsurface morphology of their glazes. The images revealed unique phase assemblage modes in different samples. The results suggest OCT may be used to identify ceramics and provide information about their manufacturing technology.

Satisfaction with Sunbelt Migration

Migration to non-metropolitan areas of high environmental amenity and low population is a lifestyle choice made by a small percentage of people on or about the age of retirement from the workforce Although the proportion of older people involved is low, their numbers are significant to host towns. An aspect of retirement migration which has received little attention by researchers in Australia is the extent to which such moves realise hoped for benefits for the migrants. This paper reports results of interviews undertaken in 1986 with 146 people who had migrated, on or about retirement, to the New South Wales north coast town of Port Macquarie. Several indicators of life and place satisfaction were used They all showed high absolute and relative levels of satisfaction. Although there was tittle dissatisfaction with the results of moves, search behaviour undertaken prior to moving and a number of personal characteristics of migrants, are analysed to explain some variance in satisfaction levels.     

Suffering,Vice, And Justice: Religious Imaginaries and Welfare Agencies in Post‐War Melbourne

Faith‐based welfare agencies vary considerably, dependent on the nature of their leadership, the inheritance of their services, and the niche that they are assigned by state policy in the mixed economy of welfare. Another dimension of their diversity can derive from the discursive structures of their faith. This article examines the theological inheritances that shaped how three key welfare agencies in post‐war Melbourne imagined what they were doing, as they drew on the diversity of teachings about the poor derived from the Catholic, Anglican, and Methodist traditions.     

USING GIS IN THE PROBABILISTIC ASSESSMENT OF EARTHQUAKE TRIGGERED LANDSLIDE HAZARDS

Summit Ridge, located in the North Santa Cruz Mountains, California, was heavily affected by landsliding during the 1989 Loma Prieta earthquake (M_w=7.0). Widespread shallow failures, along with 17 deep-seated landslides, caused extensive damage. In order to study possible methods of assessing landslide hazard a geographical information system (GIS) was utilised. Geological, geotechnical, geomorphological and seismological data were used in a deterministic analysis using two standard earthquake slope stability models (pseudo-static and Newmark displacement). The models were used to assess the landslide potential that existed during the Loma Prieta event. It was found that, of these two models, the Newmark displacement model proved most successful at predicting the location of shallow unstable slopes. However, because both models are deterministic in nature they did not take into account any of the error and uncertainty in the input parameters. Therefore, a probabilistic Newmark displacement method of analysis was developed. This was achieved by incorporating the principles behind a recently developed probabilistic technique which utilises the pseudo-static slope stability model. The method calculates the probability that a slope will exceed a certain critical value of Newmark displacement and thus fail. The use of such an analysis resulted in a more realistic distribution of hazard when compared with the distribution of actual landslides triggered by the 1989 earthquake. Subsequent to this, the probabilistic method was used to undertake a landslide hazard assessment for Summit Ridge given a postulated earthquake located on the Northern East Bay segment of the Hayward fault.
