Geographical information science: GeoComputation and non-stationarity
No full textI IntroductionIn the previous report on geographical information science (GIS) I chose to concentrate on a single theme: uncertainty and geostatistics (Atkinson, 1999). In this report, I also focus on a single theme: nonstationary geostatistics. I have chosen to present this theme within the context of GeoComputation, which I describe first
Violence in Aboriginal Australia: colonisation and gender: part I. by Judy Atkinson
No full textJudy Atkinson is a Murri woman from Queensland who was assigned by the Federal Government to write a report on Aboriginal women and violence
Terry Atkinson : Re-Writing and Re-Reading, "Tourism I and II"
No full textConsidering both the self and the art work as text, Atkinson draws on theories of language to question "the artist", the self, writing, and meaning. He then interrogates the re-reading of a single work
Don Gill : Perils of Leisure / Terry Atkinson : Tourism I & II
No full textBate borrows Foucault's metaphor of the panopticon in criticizing cultural practices associated with the "vulgarisation of leisure". Jeffries looks at Atkinson's photos of tourist rites as both private and public spaces and suggests that Gill's photos of recreational activities question the use of leisure time. Includes a comment by Atkinson. Biographical notes. 14 bibl. ref
A new factorial decomposition for the atkinson measure
No full textIn this article we explore an alternative factorial decomposition for Atkinson indices and taking Sala-i-Martin's (2002) article “The Disturbing ''Rise'' of Global Income Inequality†as a reference, the possibilities of Atkinson indices are shown in regard to completing and detailing information in studies of inequality among populations and populations subgroups.Atkinson Inequality Measure
Welfare Economics and Giving for Development
No full textThe economics of welfare is at the heart of economics, but in recent decades welfare economics has been relegated to the sidelines. While economists routinely make policy recommendations, or statements about economic success or failure, they often do so without apparent awareness of the ethical foundations for their conclusions. Yet, the foundations for welfare economics are far from solid. The standard formulation imposes severe constraints on the information that is taken into account when making evaluative judgments. The adoption of a welfarist social welfare function rules out any information other than individual welfare. In this paper, I consider the implications for welfare economics of one specific issue: individual giving for world development. While giving for development is modest in total amount, it is one of the few direct ways in which individuals reveal information relevant to the properties of the social welfare function to be applied to global redistribution. I begin by examining individual motives for giving, arguing that giving for the specific purpose of development cannot be adequately explained by the standard models of “warm glow” or “public goods”. An alternative is proposed, where people “frame” their giving in a way that gives meaning to their individual contribution. This alternative may well take a non-welfarist form. I go on to consider the implications for the social welfare function. What are the implications, if any, for the social welfare function of individual altruism towards people in poor countries? Finally, I address explicitly the geographical dimension, and the fact that the social welfare is a national social welfare function, which has to take into account the limited “sphere of control” of national governments
Experimental design on the simplex
No full textOptimum experimental designs depend on the design criterion, the model and
the design region. The talk will consider the design of experiments for regression
models in which there is a single response with the explanatory variables lying in
a simplex. One example is experiments on various compositions of glass such as
those considered by Martin, Bursnall, and Stillman (2001).
Because of the highly symmetric nature of the simplex, the class of models that
are of interest, typically Scheff´e polynomials (Scheff´e 1958) are rather different
from those of standard regression analysis. The optimum designs are also rather
different, inheriting a high degree of symmetry from the models.
In the talk I will hope to discuss a variety of modes for such experiments. Then
I will discuss constrained mixture experiments, when not all the simplex is available
for experimentation. Other important aspects include mixture experiments
with extra non-mixture factors and the blocking of mixture experiments.
Much of the material is in Chapter 16 of Atkinson, Donev, and Tobias (2007).
If time and my research allows, I would hope to finish with a few comments on
design when the responses, rather than the explanatory variables, lie in a simplex.
