Hunt angels

Rupert Kathner (Ben Mendelsohn) always had stars in his eyes. He wanted to make movies and wanted the whole world to see them. It was at a screening of a pilot for one of his films to studio execs that he met a woman who would change his life. Alma Brooks (Victoria Hill) was working as a secretary at the studio when she met Rupe. When they paired up, a revolutionary filmmaking duo was born. Despite opposition from the Police Commissioner himself, they produced the first true crime movie ever made in Australia: 'The Pyjama Girl Murder Case'. In the end, even the Commissioner gave it his blessing and it was an instant success. In fact, every film they ever made was shown on the big screen. Over the course of 15 years together, these mavericks managed to make a remarkable nineteen movies

Potential uses of ultrasound in the dairy ultrafiltration processes

There has been a growing interest in the industrial application of ultrasound, especially in the food industry. Power ultrasound can have a number of physical effects; it can increase turbulence through both the introduction of vibrational energy and through acoustic streaming, it can cause both particle agglomeration and particle dispersion and clean surfaces with a scouring action. Our work in this area has focused on the use of ultrasound to enhance membrane processing. Low frequency ultrasound has been used to facilitate cross flow ultrafiltration of dairy whey solutions for both during the ultrafiltration production cycle and the cleaning cycle. During the production cycle, the use of ultrasound reduces both pore blockage and the specific resistance of the fouling cake layer. This leads to higher flux rates and the potential for longer production cycles. During the cleaning cycle, ultrasound systematically increases cleaning efficiency, thus has the potential to reduce both total chemical consumption and system downtime. There was no deterioration in cleaning effectiveness or membrane condition which imples that sonication , has not damaged the membrane itself. Similarly, there was no change in the chemical nature of soluble proteins following sonication.

Characterisation of nickel(II) extraction by 2-hydroxy-5-nonylacetophenone oxime (LIX 84) in a micellar phase

The properties of the nickel(II)/2-hydroxy-5-nonylacetophenone oxime (HNAPO), an active ingredient in LIX 84, extraction system were characterised in a micellar system. The extinction coefficient, λ_max of HNAPO (316 nm) and the Ni²⁺ complex (387 nm) in a neutral micellar system, poly dispersed octa-ethyleneglycol mono-n-dodecyl ether (G₁₂A₈) were determined as 3100 and 3500 M⁻¹ cm⁻¹, respectively. HNAPO was found to have a neutral micellar phase and bulk aqueous phase pK_a of 11.5 and 12.5, respectively. The extraction equilibrium constant, K_ex, was determined to be 10^−8.0, and the deviation from theory observed at high pH can be accounted for by consideration of the competition for nickel(II) ions by hydroxide ions and HNAPO. A micellar phase of octa-ethyleneglycol mono-n-dodecyl ether (C₁₂E₈) was determined to be an appropriate model of the free oil/water interface from the solubilised location of HNAPO. Utilising the interfacial probe, 4-heptadecyl-7-hydroxy coumarin (HHC) allowed the determination of the electrostatic surface potential of mixed micelles of G₁₂A₈ and sodium dodecyl sulphate (SDS) or dodecyl trimethyl ammonium chloride (DTAC). The electrostatic surface potential was a linear function of the number of additional surfactant monomers within the G₁₂A₈ micelle, for the concentration range studied. For G₁₂A₈/DTAC mixed micelles, the surface potential was given by +1.1 mV per DTAC molecule per micelle, and for G₁₂A₈/SDS mixed micelles the relationship was −1.4 mV per SDS molecule per micelle.

What (a) difference a degree makes : the evaluation of the new social work degree in England

After many years of debate in the UK about the need for a degree-level qualification in social work, the arguments for a minimum degree-level qualification were accepted. The requirements for the degree in England were developed drawing on work from a number of sources, including a benchmark statement for undergraduate degrees in social work and focus groups with stakeholders. The new degree in England, launched in 2003, involves one extra year’s study; improvements in the qualifying standard for social work; and specific curriculum and entrance requirements. At the time of launching the degree, the government department responsible for funding (Department of Health) commissioned a three-year evaluation of the implementation of the new degree to establish whether the new qualifying level leads to improvements in the qualified workforce. The aim of the evaluation is to describe the experiences of those undertaking the degree, collect the views of the various stakeholders about the effectiveness of the degree and measure the impact of a degree-level qualification on those entering the workforce. This article, written by the team undertaking the evaluation of the England degree, explores the reasons for the methodological approach adopted and the issues that have arisen in setting up the research.

Measuring responses to dance : is there a 'grammer' of dance?

This paper reports a series of experiments that investigated how dance artists learn to see and understand dance. We measured, in real time, the responses of a number of dance artists and students, to a range of different dance stimuli to gain an understanding of how observers respond to structural elements of dance as they unfold over time.

A quantitative approach to analysing reliability of engagement responses to dance

Perhaps one of the most important end products of a dance work is how it  effects its observers (typically its audience, but also the dancers and choreographers). Of the many ways of discussing and analysing dance, one
approach in its infancy is quantification. Our research involves combining continuous response techniques and human response methods to see if we can tease out relationships between continuous, quantitative evaluative responses and the more qualitative choreographer intentions. The aim of this paper is to describe how evaluative responses can be quantified at all, then how they can be related to an unfolding dance work, and finally, how we can isolate ‘meaningful’ or ‘significant’ or ‘reliable’ evaluations of a dance work from those which are no more than a spurious set of not-very-useful numbers presented under the guise of a valid assessment.

Aligning school reform and teacher education reform in the middle years : an australian case study

This paper discusses the development of a new Bachelor of Education (Middle Years of Schooling) at The University of Queensland. The middle years of schooling have increasingly been the focus of education reform initiatives in Australia, but this has not been accompanied by significant increases in the number of teacher education institutions offering specialised middle schooling-level teacher preparation programmes. Considering the rapidly changing social and economic context and the emergent state of middle schooling in Australia, the programme represented a conceptual and practical opportunity and challenge for The University of Queensland team. Working collaboratively, the team sought to design a teacher education preservice programme that was both responsive and generative: that is, responsive to local school contexts and to current educational research and reform at national and international levels; and generative of cutting-edge theories and practices associated with middle schooling, teachers' work, and teacher education. This paper focuses on one component of the Middle Years of Schooling Teacher Education programme at The University of Queensland; namely, the practicum. We first present the underlying principles of the practicum programme and then examine "dilemmas" that emerged early in the practicum. These issues and tensions were associated with the ideals of "middle years" philosophy and the pragmatics of school reform associated with that new approach. In this paper, and within this context, we explore what it means to be both responsive and generative, and describe how we as teacher educators negotiated between the extremes these terms implied.

Measuring audience response on-line : an evaluation of the portable audience response facility (pARF)

If it is the case that artists and art explore organization of the brain (Zeki & Lamb, 1994), then the investigation of response to artistic performance holds promise as a window to perceptual and cognitive processes. The portable Audience Response Facility (pARF) is an instrument for recording real‐time audience response (Stevens et al. 2009). Twenty, handheld, Personal Digital Assistants (PDAs) collect responses on customizable skin interfaces. The pARF server transmits the customizable options, synchronizes devices and collects data for export. In this paper we report ratings of the usability of the pARF that were collected after 37 participants had used it to continuously rate engagement along a single dimension while a female dance artist gave two performances of a short solo contemporary dance work. The motion of the dancer was also captured as she performed the piece but only usability rating data are reported here. Ratings indicate that the cognitive load imposed by continuously rating engagement while watching a dance performance was manageable and the pARF was easy to use. An extended familiarization phase may further reduce dual task demand.

The application of ultrasound to dairy ultrafiltration : the influence of operating conditions

Work previously presented has shown that ultrasound can be effective in enhancing both the production and cleaning cycles of dairy membrane  processes. In this present work we extend these previous results to consider the effect of ultrasonic frequency and the use of intermittent ultrasound. These results show that the use of continuous low frequency (50 kHz) ultrasound is most effective in both the fouling and cleaning cycles. The application of intermittent high frequency (1 MHz) ultrasound is less effective. At higher transmembrane pressure, high frequency pulsed sonication can indeed lead to a reduction in steady state membrane flux. The benefits of ultrasound arise from a reduction in both concentration polarization and in the resistance provided by the more labile protein deposits that are removed during a water wash. Conversely, the loss of membrane flux when high frequency pulsed sonication is used arises from a significant increase in the more tenacious ‘irreversible’ fouling deposit.
