Robert George Cameron : the First Professor of Education, at UWA 1927-1954

There has been much debate about the status of Education as a field of study within universities. In many circumstances the evidence suggests that there was hostility towards the inclusion of Education within the university curriculum. The fact that ‘teacher training was never accepted at the Universities of Sydney or Melbourne in the same manner as the professional training courses such as Medicine, Law or Engineering’ (Bessant and Holbrook, 1995. p.266) was a legacy of the association of teaching with the public service and apprenticeship training

Atmospheric observations of the water vapour continuum in the near-infrared windows between 2500 and 6600 cm-1

Water vapour continuum absorption is potentially important for both closure of the Earth's energy budget and remote sensing applications. Currently, there are significant uncertainties in its characteristics in the near-infrared atmospheric windows at 2.1 and 1.6 µm. There have been several attempts to measure the continuum in the laboratory; not only are there significant differences amongst these measurements, but there are also difficulties in extrapolating the laboratory data taken at room temperature and above to temperatures more widely relevant to the atmosphere. Validation is therefore required using field observations of the real atmosphere. There are currently no published observations in atmospheric conditions with enough water vapour to detect a continuum signal within these windows or where the self-continuum component is significant. We present observations of the near-infrared water vapour continuum from Camborne, UK, at sea level using a Sun-pointing, radiometrically calibrated Fourier transform spectrometer in the window regions between 2000 and 10 000 cm−1. Analysis of these data is challenging, particularly because of the need to remove aerosol extinction and the large uncertainties associated with such field measurements. Nevertheless, we present data that are consistent with recent laboratory datasets in the 4 and 2.1 µm windows (when extrapolated to atmospheric temperatures). These results indicate that the most recent revision (3.2) of the MT_CKD foreign continuum, versions of which are widely used in atmospheric radiation models, requires strengthening by a factor of ∼5 in the centre of the 2.1 µm window. In the higher-wavenumber window at 1.6 µm, our estimated self- and foreign-continua are significantly stronger than MT_CKD. The possible contribution of the self- and foreign-continua to our derived total continuum optical depth is estimated by using laboratory or MT_CKD values of one, to estimate the other. The obtained self-continuum shows some consistency with temperature-extrapolated laboratory data in the centres of the 4 and 2.1 µm windows. The 1.6 µm region is more sensitive to atmospheric aerosol and continuum retrievals and therefore more uncertain than the more robust results at 2.1 and 4 µm. We highlight the difficulties in observing the atmospheric continuum and make the case for additional measurements in both the laboratory and field and discuss the requirements for any future field campaign

The Construction Of Education as an Area of Study at Murdoch University: 1974-2003

This paper is concerned with the extent to which both structural and agency factors were at play in the establishment and maintenance of an innovative model of Education Studies at Murdoch University in Western Australia, from the mid 1970s to 2003. Regarding structural factors, the fact that the University was established as one of a number of ‘new’ universities on the national scene, with a brief to break out of the curricular traditions of the established universities, meant that there was latitude for the adoption of new curriculum structures in outlining the parameters of Education Studies. However, it required the agency of Brian Hill, the Foundation Professor of Education, to make this happen. The paper outlines how the nature of the model that eventuated was largely a transfer of models which Hill witnessed both in North America and within Australia and which he adapted to local conditions, seeking in the process to bring about what he considered to be an improved composite version based on his professional experience in a number of universities

A LinkedIn Analysis of Career Paths of Information Systems Alumni

Information harvested from the LinkedIn profiles for 175 graduates of an Information Systems program at a mid-sized comprehensive university in Southeastern USA are summarized in this investigation. The current investigation was undertaken to examine the extent to which LinkedIn profiles are able to provide a more realistic picture of entry-level jobs held by program alumni and subsequent career progress. In addition, our results suggest that LinkedIn profiles can help answer questions such as: “What jobs do IS graduates get?”, “What does the career of an IS professional typically look like?”, and “Whether IS graduates can successfully transition from technical to managerial positions?”. Our findings also suggest that information in LinkedIn profiles can be used to assess the long-term outcomes of IS programs

On Lundh's percolation difussion

A collection of spherical obstacles in the ball in Euclidean space is said to be avoidable for Brownian motion if there is a positive probability that Brownian motion diffusing from some point in the ball will avoid all the obstacles and reach the boundary of the ball. The centres of the spherical obstacles are generated according to a Poisson point process while the radius of an obstacle is a deterministic function depending only on the distance from the obstacle's centre to the centre of the ball. Lundh has given the name percolation diffusion to this process if avoidable configurations are generated with positive probability. An integral condition for percolation diffusion is derived in terms of the intensity of the Poisson point process and the function that determines the radii of the obstacles

Can measurements of the near-infrared solar spectral irradiance be reconciled? A new ground-based assessment between 4000-10000 cm-1

The near-infrared solar spectral irradiance (SSI) is of vital importance for understanding the Earth’s radiation budget, and in Earth observation applications. Differences between previously published solar spectra (including the commonly-used ATLAS3 spectrum) reach up to 10% at the low-wavenumber end of the 4000-10000 cm-1 (2.5 – 1 μm) spectral region. The implications for the atmospheric sciences are significant, since this spectral region contains 25% of the incoming total solar irradiance. This work details an updated analysis of the CAVIAR SSI, featuring additional analysis techniques and an updated uncertainty budget using a Monte Carlo method. We report good consistency with ATLAS3 in the 7000-10000 cm-1 region where there is confidence in these results due to agreement with other spectra, but ~7% lower in the 4000-7000 cm-1 region, in general agreement with several other analyses
