Understanding and enhancing pupils' learning progress in schools in deprived communities
This paper draws on data from the ‘Raising Pupil Attainment in Key Stage 1 in Stoke-on-Trent’ research project. The particular focus is on how teachers, head teachers and teaching assistants (n = 59) articulate pupils’ learning success in five highly achieving schools in deprived communities. Six key themes are highlighted which are identified by participants as influencing successful pupil learning and progress. These are analysed in relation to Biesta's theory on the parameters of ‘Good Education’ [Biesta, G. J. J. 2010. Good Education in an Age of Measurement. Boulder, CO: Paradigm] and within Bourdieu's understanding of ‘distinction’ [Bourdieu, P. 1998. Practical Reason: On the Theory of Action. Oxford: Polity Press]. The research reveals that issues related to socialisation and subjectivity are presented as critical and foundational for the more formal measures of success in pupil learning
Temperature measurements behind reflected shock waves in air
A radiometric method for the measurement of gas temperature in self-absorbing gases has been applied in the study of shock tube generated flows. This method involves making two absolute intensity measurements at identical wavelengths, but for two different pathlengths in the same gas sample. Experimental results are presented for reflected shock waves in air at conditions corresponding to incident shock velocities from 7 to 10 km/s and an initial driven tube pressure of 1 torr. These results indicate that, with this technique, temperature measurements with an accuracy of + or - 5 percent can be carried out. The results also suggest certain facility related problems
CFD designed experiments for shock wave/boundary layer interactions in hypersonic ducted flows
The successful operation of scramjet combustors requires compression of hypersonic viscous ducted flows and avoidance of separation effects which may preclude steady flow. Separation effects in scramjet inlets and combustors can be caused by shock wave/boundary layer interactions. The hypersonic turbulent flow experiments needed are inherently difficult to design because of the high sensitivity of the macroscopic flow parameters which cause the turbulent flow processes. Hence computational fluid dynamics (CFD) is a useful tool for the design and characterisation of models in hypersonic flows before model construction. One of the greatest challenges however is to ensure that the flow is being modeled accurately. In this paper, a commercial code has been used to model an experiment performed in a small reflected shock tunnel using a Mach 8.65 condition. The research being carried out in this facility is concerned with separation due to incident shock wave/turbulent boundary interactions in hypersonic ducted flows. The model is designed to produce two conical shocks which interact with a turbulent boundary layer and it is instrumented with pressure transducers and thin film heat transfer gauges. The measurements have allowed graphical representation of unseparated static wall pressure and heat flux prior to and after each wall interaction. The results of the simulations are in excellent agreement with the experimental data. The code has been applied to identify parameter boundaries in the design of a model of similar scale that will produce separated flow
Timing of breeding and diet of the Black-faced cormorant Phalacrocorax fuscescens
Previous anecdotal reports have suggested that Black-faced Cormorant Phalacrocorax fuscescens breeds only in winter in southeastern Australia, but detailed reports confirming this are lacking. Here we examine the timing of breeding in Black-faced Cormorants at Notch Island in northern Bass Strait in 2006. Peak laying occurred during winter (ca 26 July). The diet of Black-faced Cormorants was predominantly fish (97% of identified prey) and varied between breeding and post-breeding periods. Black-faced Cormorants consumed a total of 14 different species with four species having a frequency of occurrence in the diet of ?5% during the breeding season and six species during the post-breeding period. We provide data for the first time on the chronology of breeding of Black-faced Cormorants in one year and give a preliminary description of their diet based on pellet analyses. We propose that late winter breeding may be a strategy to avoid the high ambient temperatures in northern Bass Strait during summer, the associated higher thermoregulatory costs for adults and the increased mortality for chicks
