The Campaign to Arrest Ed Shann’s Influence in Western Australia

Shann towered over the discipline of economics in the state of Western Australia in the first third of the twentieth century. He was the foundation professor in history and economics from 1913 to 1931 and inaugural professor of economics from 1931 to 1934 at the University of Western Australia (UWA); he set the curriculum for the subjects that constituted the economics major that was offered at UWA over this period and ensured that it had a market-driven, policy-oriented and historical flavour; he trained a generation of bright young men and women—such as John La Nauze, Nugget Coombs, Merab Harris, Paul Hasluck, Arthur Tange and Alexander Reid—who drew upon his teachings (even when they disagreed with certain elements of it) to guide their actions as servants of the public; he exploited his contacts in the commercial and professional world of Perth to draw men of intellect, but not formal economic training, into the newly established local branch of the Economic Society of Australia and New Zealand in 1925; he established close contacts with local men of finance, including Alfred Davidson of the Bank of New South Wales, in a way that eventually allowed him (and his students!) to provide policy advice at a national level; and he used his power as an administrator, at one time acting as the Vice Chancellor of the university, to establish a faculty of law and a diploma in journalism, both of which thereafter had close associations with the economics discipline at UWA. Shann, in short, created the discipline of economics in Western Australia in his own image. Unfortunately, however, a number of powerful identities in Perth resented the free-market commentaries that Shann dispensed in the public domain and before his students, and hence orchestrated a public campaign to arrest his influence. In this paper I provide an account of Shann’s influence in Western Australia from 1913 to 1934 and trace the campaign waged against him (and economics) which eventually induced him to leave this state

Calibration of seven-hole pressure probes for use in fluid flows with large angularity

Described here is the calibration of a non-nulling, conical, seven-hole pressure probe over a large range of flow onset angles. The calibration procedure is based on the use of differential pressures to determine the three components of velocity. The method allows determination of the flow angle to within 0.5 deg and velocity magnitude to approximately 1.0 percent. Also included is an examination of the factors which limit the use of the probe, a description of the measurement chain, an error analysis, and a typical experimental result. In addition, a new general analytical model of pressure probe behavior is described and the validity of the model is demonstrated by comparing it with experimentally measured calibration data for a three-hole yaw meter and a seven-hole probe

Dark Corners in a Bright Economy; The Lack of Jobs for Unskilled Men

This paper discusses the large reductions in full-time employment among unskilled Australian males that began in the 1970's and continued over the next three to four decades. Over this period, each recession led to large falls in the male full-time employment-population ratio and during each economic recovery the employment ratio failed to move back to previous levels. Unemployment fell during each output recovery, not in response to employment gains, but in response to large scale withdrawals from the labour market into the welfare system. The loss of unskilled jobs for men has been associated with falling marriage rates and increasing use of the welfare system by single women. The paper concludes by briefly assessing some of the impacts of the new resource boom on these long run labour market and welfare trends and discusses the potential for different labour market outcomes emerging across mineral and non-mineral states.Employment, Unskilled jobs

Projective toric varieties as fine moduli spaces of quiver representations

This paper proves that every projective toric variety is the fine moduli space for stable representations of an appropriate bound quiver. To accomplish this, we study the quiver $Q$ with relations $R$ corresponding to the finite-dimensional algebra $\bigl(\bigoplus_{i=0}^{r} L_i \bigr)$ where $\mathcal{L} := (\mathscr{O}_X,L_1, ...c, L_r)$ is a list of line bundles on a projective toric variety $X$. The quiver $Q$ defines a smooth projective toric variety, called the multilinear series $|\mathcal{L}|$, and a map $X \to |\mathcal{L}|$. We provide necessary and sufficient conditions for the induced map to be a closed embedding. As a consequence, we obtain a new geometric quotient construction of projective toric varieties. Under slightly stronger hypotheses on $\mathcal{L}$, the closed embedding identifies $X$ with the fine moduli space of stable representations for the bound quiver $(Q,R)$.Comment: revised version: improved exposition, corrected typos and other minor change
