A theory of injustice: the flip side of the relocation coin in Australia

Problems attached to relocation cases in Australia because of geographical and cultural reasons - the best interests of the child principle inherently promotes injustice in relocation cases - operation of Part VII of the Family Law Act in the context of relocation cases - assessment of the best interests of the child principle in Australian relocation cases - responsibility of contact parents - reforming Australian law to promote an equality of interests.

Leadership that promotes organizational learning : both sides of the coin

Purpose – The purpose of this paper is to demonstrate how leadership has the capacity to both positively influence learning processes and negatively inhibit organizational learning.

Design/methodology/approach – This is a conceptual paper that brings together an analysis of leadership and organizational learning literature. The argument is centered on transformational leadership and the responsibility for creating an organizational learning culture.

Findings – There is a conventional belief that leaders have solitary control and influence when it comes to setting up organizational learning processes. However, a top-down approach to facilitate and implement learning in organizations is not always an effective method because learning should be a collaborative practice. Thus, to rely fully on leaders to initiate and sustain the learning processes can be counter-productive.

Practical implications – Good and effective leadership is the key to organizational learning. Learning is the only sustainable method of achieving competitive advantage for contemporary organizations because of rapidly changing environmental forces. Corporations with aspirations for long-term survival must facilitate, through their leadership, “the impulse to learn” amongst their members.

Originality/value – Knowledge is lacking in the area where leadership is linked to learning. Such knowledge is important because leaders play a central role in the learning framework and leaders also offer the required guidance for organizations to integrate and sustain learning processes through policy and practice.

Reconstruction of the refractive index profile of planar waveguides using ray tracing analysis

We propose a method for refractive index profiling based on measuring coordinates and angles of laser beams passing across the waveguide layer. Calculations are performed by solving an integral equation using new global optimization methods.

Women primary principals in independent schools : creativity and inspiration

The purpose of my research is to reinvigorate educational leadership through improved understandings of women primary principals in Independent schools, thereby rethinking the current directions. By 'reinvigorate' I mean investigate what serves as inspiration for current women primary leaders and explore how this might be better used to generate the kinds of educational change that lead to more dynamic primary school leadership. These 'improved understandings' are expected to suggest a reconceptualizing of primary school leadership by, what I coin 'response-ability'. By 'response-ability' I mean to expose untapped potentials in primary leadership performance so that the leader utilizes the full range of their knowledge, skills and values.

There are acknowledged gaps in the primary school Independent sector concerning women in leadership both theory and practice and in this instance the Victorian context. Considerable research surrounds educational leadership [Peter Hill (2003), Neil Cranston (2001), Frances Townsend (1999),Helen Telford.(1996) and Caldwell & Spinks (1992)]. In particular Jill Blackmore's, (1999) research analysed a number of projects focusing on women secondary principals. As a critique of leadership her research exposed the gendered influences reinforced through culture, values and language

However there has been limited research into women in primary leadership and the implications for the Independent sector. In summary this research aims to understand women in primary educational leadership and investigate the significance of their untapped knowledge, skills, attitudes and values. Furthermore to propose what may constitute 'Response-able' leadership that could serve to highlight ethical principles, authenticity and creativity.

Harvesting waste thermal energy using a carbon-nanotube-based thermo-electrochemical cell

Low efficiencies and costly electrode materials have limited harvesting of thermal energy as electrical energy using thermo-electrochemical cells (or “thermocells”). We demonstrate thermocells, in practical configurations (from coin cells to cells that can be wrapped around exhaust pipes), that harvest low-grade thermal energy using relatively inexpensive carbon multiwalled nanotube (MWNT) electrodes. These electrodes provide high electrochemically accessible surface areas and fast redox-mediated electron transfer, which significantly enhances thermocell current generation capacity and overall efficiency. Thermocell efficiency is further improved by directly synthesizing MWNTs as vertical forests that reduce electrical and thermal resistance at electrode/substrate junctions. The efficiency of thermocells with MWNT electrodes is shown to be as high as 1.4% of Carnot efficiency, which is 3-fold higher than for previously demonstrated thermocells. With the cost of MWNTs decreasing, MWNT-based thermocells may become commercially viable for harvesting low-grade thermal energy.

Automatic attribution of ancient Roman imperial coins

Classification of coins is an important but laborious aspect of numismatics - the field that studies coins and currency. It is particularly challenging in the case of ancient coins. Due to the way they were manufactured, as well as wear from use and exposure to chemicals in the soil, the same ancient coin type can exhibit great variability in appearance. We demonstrate that geometry-free models of appearance do not perform better than chance on this task and that only a small improvement is gained by previously proposed models of combined appearance and geometry. Thus, our first major contribution is a new type of feature which is efficient in terms of computational time and storage requirements, and which effectively captures geometric configurations between descriptors corresponding to local features. Our second contribution is a description of a fully automatic system based on the proposed features, which robustly localizes, segments out and classifies coins from cluttered images. We also describe a large database of ancient coins that we collected and which will be made publicly available. Finally, we report the results of empirical comparison of different coin matching techniques. The features proposed in this paper are found to greatly outperform existing methods.

Reading ancient coins: automatically identifying denarii using obverse legend seeded retrieval

The aim of this paper is to automatically identify a Roman Imperial denarius from a single query photograph of its obverse and reverse. Such functionality has the potential to contribute greatly to various national schemes which encourage laymen to report their finds to local museums. Our work introduces a series of novelties: (i) this is the first paper which describes a method for extracting the legend of an ancient coin from a photograph; (ii) we are also the first to suggest the idea and propose a method for identifying a coin using a series of carefully engineered retrievals, each harnessed for further information using visual or meta-data processing; (iii) we show how in addition to a unique standard reference number for a query coin, the proposed system can be used to extract salient coin information (issuing authority, obverse and reverse descriptions, mint date) and retrieve images of other coins of the same type.

The raising of corporate sponsorship: a behavioral study

Research was conducted in order to define a "buyer behavior" process for the purchase of sponsorship at a corporate level. A series of interviews was carried out with a number of organizations that are currently involved in sponsorship of varying kinds. A consideration was made to include a balance of sponsorship types-small and large-as well as arts, sports, and events, although no attempt was made to identify how the process differs across sponsorship type. Our results show that while sponsorship and fundraising are flipsides of the same coin from the nonprofit sponsorship-seeker's perspective, the sponsorship provider sees the act of sponsorship as a commercial profit-making venture. This is a conundrum that has wide-reaching consequences for the sector. © 2012 Copyright Taylor and Francis Group, LLC.

Queering archives: intimate tracings

In the longer introduction of Radical History Review’s two thematic issues “Queering Archives,” we frame the archive as an evasive and dynamic space animated by the tensions of knowledge production, absence, and presence. As Jeffrey Weeks argued in RHR in 1979, “The evolution of sexual meanings and identities that we have traced over the past hundred years or so are by no means complete.”1 Fragments of information float unfixed — historically unraveled — and we form archives when we pull the fragments into the orbit of efforts to know. Yet the business of knowing is unsteady, as scholars of sexuality and gender have amply demonstrated. Between the fraught and necessary practices of historicization, anachronism, interpretation, bias, and partial readings that propel historical scholarship, archival fragments fall in and out of the frame of an easily perceptible knowledge. Queer historical knowledge thus is evasive — like a coin dropped in the ocean and for which one grasps, reaching it only for it to slip away again, rolling deeper into the beyond. To say that the knowledge work of animating queer historical fragments is marked by such slipperiness is to underline how the archive negotiates the decomposition and recomposition of knowledge’s materials. We pull and push at the fading paper, the fraying fabric, the photographs bleaching into their backgrounds, and manipulate technologies on their way to obsolescence, all as part of some suturing effort of one kind or another.

A miniature neural recording device

This paper presents a portable neural recording device for use with laboratory animals. It can detect and record neural signals from the cortical region of the brain during pre-clinical trials. The device utilizes simplified circuitry to perform signal detection, filtering, sampling, and storage. It includes analog and digital components each implemented on a separate small printed circuit board. The two printed circuit boards are then attached to one another to form the device. It is capable of uninterrupted operation for over 2 hours on a single coin battery. A bench-testing of the device was performed with pre-recorded neural signal which then injected to the input of the device to give validation of efficient operation of the device. Its amplification and filtration features have been analyzed. An overall 56 dB amplification and filtration in the frequency range of 300 Hz to 4 KHz was achieved. Sampling and storage at a reduced power and computational load is demonstrated with uninterrupted storage of the neural signal. A comparison of the input and reconstructed neural signals shows minimal variation error.

The Museum of Doubt

Is there a God? Does my bum look big in this? Why doesn’t my house cost only the materials used to build it? Is Video Art dead? When Peter Hill curated his first Museum of Doubt exhibition at Zeppelin Projects in Brunswick, these were some of the questions his artist friends wrote on one wall of the gallery. Those artists included Jon Cattapan, Phil Edwards, Julian Goddard, Ceri Hahn, and Peter Ellis. Others, who are also in this second outing of The Museum of Doubt, include Louise Weaver, Patrick Pound, Josh Foley and Michael Vale. How do we know what is true or false in any given visual statement? How willing are we to suspend our disbelief? And does that even matter if the artworks can be enjoyed for their own formal beauty, angst, or inquisitiveness?“I have a great sympathy with both doubt and faith as beacons for navigating this sublime universe,” says Peter Hill. “Remembering that the sublime in art, as in life and death, hovers between beauty and terror. Doubt and faith are both on the same side of the same coin – a coin that has “certainty” on the reverse. Most of the problems we face today are caused by individuals and nations being “certain” that they have the answer. Don’t listen to them. Be skeptical. The truth can be approached, as Karl Popper, the great philosopher of science tells us, but it can rarely be found. It can only be falsified.”So bring your doubt and your faith to this Wunderkammer of Super Fictions and enjoy the lightness, the darkness, and the strangeness in the works of: Glen Clarke, Josh Foley, Tony Garifalakis, Grant Hill, Peter Hill, Patrick Pound, Michael Vale, Louise Weaver and Robert Zhao.
