ESTIMATING TEMPORAL FARM INCOME DISTRIBUTIONS USING SPATIAL SMOOTHING TECHNIQUES

The Australian Bureau of Agricultural & Resource Economics (ABARE) has conducted the annual Australian Agricultural and Grazing Industries Survey, covering the broadacre sector, in a consistent format since 1978/79. In this period the incomes of farmers have fluctuated considerably. Interest has focused on temporal income variation because of its relationship to the inherent riskiness of farming. Part of these income fluctuations can be explained by changing commodity prices and by highly variable climatic conditions. This paper outlines a method of measuring the magnitude of this income variation and how it relates to other variables. Due to rotation within the sample of farms surveyed, data are limited for determining the income variability of any particular farm. This paper, using spatial locations of surveyed farms, shows how kernel smoothing techniques can be adapted to estimate the distribution of a farm's income. This analysis uses data collected from 1978/79 to 1991/92. Summary information from these distributions is cross-tabulated against several other variables. This shows that income variability is strongly related to the production mixture of farming businesses.     

Individual-level sterility: A new method of estimation with application to sub-saharan Africa

This paper extends work on measures of population proportions sterile to propose a new estimator of an individual woman's age at sterility and consequently her sterility status at given ages. Accuracy and reliability, examined in a simulation study, appear satisfactory. From World Fertility Survey data for five African countries, the proportions sterile by age estimated by the individual measure and by the population estimator are almost identical. Cameroon and Kenya show substantial variation in prevalence and incidence of sterility across ethnic groups and by number of marriages. Unexpectedly, the evidence suggests that sterility increased from 1960 on in Kenya and remained unchanged in Cameroon.     

Welcome to the Real World of Clinical Research

Perhaps we should take a deep breath! We have successfully gained approval from three Area Health regions for a multi‐centre study, which assesses the effectiveness of a group program for parents of children with challenging behaviour. Each Ethics Committee had to have its say, and change a few things, but we were able to jump their hurdles without (we thought) over‐complicating a relatively no‐frills project. We were also extremely lucky that the project had received funding from the Centre for Mental Health. Without funding, it would have been difficult to afford essential research goodies, such as questionnaires at $2.50 per form, or even paper, adding up to several thousand dollars.     

Individual differences in the perception of occupational stress and their association with blood pressure status

Casual blood pressure (BP) was recorded in a sample of 217 working adults. A questionnaire was used to obtain subjective reports of job stress. comparisons were made between a group with elevated BP and a normotensive group. The high BP group appeared to perceive more stress. In particular, scores on the role conflict, job versus non-job conflict and type A scales reliably differentiated the groups. In contrast, for the job satisfaction items, no difference between the groups was observed. There appeared to be some association between reported occupational stress and BP level.     

Groups for Incest Survivors; A New Context

This article outlines a new context for group work with young women who have experienced incest. It describes how ideas from the work of White, Epston, Kamsler and de Shazer on the evolution, maintenance and resolution of problems can be applied to enhance the therapeutic effectiveness of group work with teenage survivors of incest. Externalisation, exploration of beliefs and restorying are found to assist the young women greatly to reconnect with their own resourcefulness.
