Blind alleys, blinding and blinded aliens : mapping the outer limits of the technical image

Marcia Jane's installation work is situated along a historic line of critical enquiry traceable back to Goethe. her energy field series re-tools for digital use the formal erasures of sturcturalist film, where the relationship between the signifier and the signified are inverted.

Duoscope

The ambiguous representation of spatial depth in Thornton Walker’s painting The Homage creates a peculiar sense in which the ‘whereness’ of depicted objects and atmosphere cannot be ascertained by, either perspectival convention or perceptual strategies. This visual-spatial ambiguity resonates with my interested in ‘broken’ stereography. Hence, ‘duoscopy’ refers to the limitations of binocular vision when the object of perception is itself duplicitous.

How doctors and lawyers can help vulnerable patients

Medical-legal partnerships have broken down the barriers to accessible legal services for people experiencing health issues in the United States. Such programs demonstrate the health benefits of effective legal advocacy on behalf of patients and Australia could learn from this model to improve access to justice and deliver better health outcomes.

The emotional labour of the aspirant leader: traversing school politics

The emotions of the aspirant leader are underexplored. In this chapter, we detail how aspirants experience the transition from teacher to leader and report on the kinds of emotional labour associated with the transition. This was examined during events of high emotional arousal for 130 school aspirants: when they felt professionally wounded, either by colleagues, leaders, parents or students. During a time of wounding, emotional work and emotional labour hinged on the dissonance between 'display rules' of the school and what aspirants' actually felt. Exploring the wounding stories revealed common display rules, which were often broken. Breaking these rules always had consequences and emotional correlates. The most prevalent form of emotional labour was surface acting. The.final discovery was the resilience of the aspirants as they recovered. Invariably, aspirants progressed through an emotion cycle of Regrouping, Recovery and Resolution. The quality of collegial relationships was the key to resolving the woundings.

A hybrid approach for multiple particle tracking microrheology

Geometric object detection has many applications, such as in tracking. Particle tracking microrheology is a technique for studying mechanical properties by accurately tracking the motion of the immersed particles undergoing Brownian motion. Since particles are carried along by these random undulations of the medium, they can move in and out of the microscope's depth of focus, which results in halos (lower intensity). Two-point particle tracking microrheology (TPM) uses a threshold to find those particles with peak, which leads to the broken trajectory of the particles. The halos of those particles which are out of focus are circles and the centres can be accurately tracked in most cases. When the particles are sparse, TPM will lose certain useful information. Thus, it may cause inaccurate microrheology. An efficient algorithm to detect the centre of those particles will increase the accuracy of the Brownian motion. In this paper, a hybrid approach is proposed which combines the steps of TPM for particles in focus with a circle detection step using circular Hough transform for particles with halos. As a consequence, it not only detects more particles in each frame but also dramatically extends the trajectories with satisfactory accuracy. Experiments over a video microscope data set of polystyrene spheres suspended in water undergoing Brownian motion confirmed the efficiency of the algorithm.

Sexual abuse in 'Disgrace' and 'Cereus Blooms at Night': the case for hope

Abuse is rife in Disgrace by J.M. Coetzee and Cereus Blooms at Night by Shani Mootoo. Sexual violence is in both narratives, part of their richly textured social, emotional and political worlds. Fiction involving various traumas seems bleak, almost hopeless, perhaps weighted by sadness. Yet both these novels, even through depictions of rupturing, disruptive rape, trigger a recognition of possibility and potential among characters and perhaps readers. It is in this open ended potential for betterment of some kind that hope lies. What is the nature of hope and to what extent is it present in these novels? In this paper, I explore the emotion of hope in relation to the notion of becoming as elaborated on by Gilles Deleuze and Felix Guattari particularly in A Thousand Plateaus. They expound on Remy Chauvin‟s term “aparallel evolution” in relation to becoming (Deleuze and Guattari, 11). Deleuze also states that becoming is not a “phenomena of imitation or assimilation”. Rather, it is an encounter, “a double capture” (Deleuze and Parnet 2) between heterogeneous elements. There is no end or destination in becoming; it is constant change. I examine the transformative potential of becoming to elicit signs of hope in these novels. David Lurie, the self-absorbed womaniser and arguably rapist, becomes-dog by the end of Disgrace. How does this contribute to any sense of redemption and consequently hope? And how does hope emanate from the beaten, broken, brutally raped Mala Ramchandin in Cereus Blooms at Night? At heart, this paper is an acknowledgment of the unique relation literature has with life and the enriching insight that it may provide into the expression of hope.

Would you like some gender with that leadership?

The recent toppling of Australia’s first female prime minister, Julia Gillard, continues to raise questions about women and leadership. Gillard was regarded as smart, capable and resilient. However, a string of bad decisions and broken promises had the public and politicians questioning her capacity to lead. In her final exit speech before Kevin Rudd took her place, Gillard responded to the “gender wars” discourse that had come to represent her leadership, saying that “the reaction to being the first female PM”—in other words, gender—did not explain everything nor did it explain nothing.

Cathode characterization with steel and copper collector bars in an electrolytic cell

This article presents finite-element method simulation results of current distribution in an aluminum electrolytic cell. The model uses one quarter of the cell as a computational domain assuming longitudinal (along the length of the cell) and transverse axes of symmetries. The purpose of this work is to closely examine the impact of steel and copper collector bars on the cell current distribution. The findings indicated that an inclined steel collector bar (φ = 1°) can save up to 10–12 mV from the cathode lining in comparison to a horizontal 100 mm × 150-mm steel collector bar. It is predicted that a copper collector bar has a much higher potential of saving cathode voltage drop (CVD) and has a greater impact on the overall current distribution in the cell. A copper collector bar with 72% of cathode length and size of 100 mm × 150 mm is predicted to have more than 150 mV savings in cathode lining. In addition, a significant improvement in current distribution over the entire cathode surface is achieved when compared with a similar size of steel collector bar. There is a reduction of more than 70% in peak current density value due to the higher conductivity of copper. Comparisons between steel and copper collector bars with different sizes are discussed in terms CVD and current density distribution. The most important aspect of the findings is to recognize the influence of copper collector bars on the current distribution in molten metal. Lorentz fields are evaluated at different sizes of steel and copper collector bars. The simulation predicts that there is 50% decrease in Lorentz force due to the improvement in current distribution in the molten metal.

Expert systems modeling for assessing climate change impacts and adaptation in agricultural systems at regional level

Australian agriculture is very susceptible to the adverse impacts of climate change, with major shifts in temperature and rainfall projected. In this context, this paper describes a research methodology for assessing potential climate change impacts on, and formulating adaptation options for, agriculture at regional level. The methodology was developed and applied in the analysis of climate change impacts on key horticultural commodities—pome fruits (apples and pears), stone fruits (peaches and nectarines) and wine grapes—in the Goulburn Broken catchment management region, State of Victoria, Australia. Core components of the methodology are mathematical models that enable to spatially represent the degree of biophysical land suitability for the growth of agricultural commodities in the region of interest given current and future climatic conditions. The methodology provides a sound analytic approach to 1) recognise regions under threat of declines in agricultural production due to unfolding climatic changes; 2) identify alternative agricultural systems better adapted to likely future climatic conditions and 3) investigate incremental and transformational adaptation actions to improve the problem situations that are being created by climate change.

Impossible triangles: flat actors in telematic theatre

In fact, in this scene, both A and B are online. A is in a classroom at the University of Amsterdam in The Netherlands, and B is in a television studio at Deakin University in Melbourne, Australia. The two locations are connected through video conference and, in each space, a local audience watches the local performer in the room, and the remote performer projected on a screen. The performers are captured in profile, and appear to be looking at computer screens in front of them but cannot actually see one another. The text is consciously banal, composed to replicate the broken rhythms and sequences, flattened tone and repetitions of scrolling words in a text box on a screen. Information about presence and absence (A or B is offline or online) is spoken as text. Although the two performers speak in accents that declare their different language/ cultures, the vernacular is generic 'internetslang'. The relatively monotonous and unpunctuated delivery of the textual rhythms is interrupted and counterpointed by a sound lag of nearly a second, and by a faint audio echo as one voice 'lands' in the second location. Its orchestration allows the sound fracture and dispersal in some moments. In other moments, the actors anticipate or absorb the gaps in transmission, driving the speech rhythms through so that the utterance 'arrives' precisely at the end of the prompt line.
