Victoria paves the way to eliminating discrimination

In April 2010, the Victorian government passed long awaited amendments to the Equal Opportunity Act 1995, which come into force in August 2011. The changes result from a review conducted by former public advocate Julian Gardner. A parallel review examined the exceptions and exemptions. Gardner’s recommendations were aimed at strengthening the Act’s effectiveness in addressing systemic discrimination and promoting substantive equality.Consequently, the Equal Opportunity Act 2010 (Vic) (EO Act 2010) introduces unique mechanisms for addressing discrimination which are worth examining in detail. This note considers the amended definitions of discrimination and focuses on the modifications of the dispute resolution process, new measures to promote substantive equality, and changes to the Victorian Equal Opportunity and Human Rights Commission’s (VEOHRC) functions.Changes to the exception and exemption provisions were examined in an earlier note.

School based partnerships : an Orff approach experiencing, exploring and engaging in music education

This article considers the role school-based partnerships can offer pre-service music education students. It is a reflection on what my students and I experienced, explored and engaged in music teaching and learning at a local primary school in Melbourne where the teacher is an Orff practitioner. As Wiggins says, 'Excellent teacher education programs provide students with experiences from which they can construct their own understandings of music, education, and music education' (Wiggins, 2007, p.36). Although both students and I kept reflective journals over our fiveweek visit during the first semester of 2008, this article selectively reports on some of my observation notes regarding music teaching and learning using the Orff approach. Such interaction paves the way for ongoing professional growth for all concerned (preservice students, music teacher and lecturer). It may be argued that school based partnerships offer students 'hands on' opportunities to 'develop an initial repertoire of teaching competencies, comprehend the various dimensions of music experience and understand student learning' (Campbell & Brummett, 2007. p.52). Although this article draws on the principal of linking theory to practice where the emphasis is on school and university partnerships (Henry, 2001) it makes pertinent links to the Orff approach to music teaching and learning.

Mothering siblings: Diaspora, desire and identity in American born confused Desi

In this essay we consider the construction of cultural identity, motherhood and the family in ABCD, a film of the Indian diaspora that had its world premiere at the 2001 London Film Festival. This film reads family, apparently within familiar narrative structures such as the U.S.-immigrant story, as portrayed in films like Goodbye, Columbus and My Big Fat Greek Wedding, and the "leaving home" story, as classically portrayed in Pride and Prejudice, where a young person needs to escape from her clueless family. The irritating presence of the mother in the film, and the quickness with which her two children appear to make life-determining decisions following her death, seem to invite discussions of plot and character organized around ideas of individual development, self-improvement and understanding. This is the territory of the desire plot, an account of family history captured for the twentieth century by Freudian-Lacanian readings which position sexual desire within the unconscious history of familial fantasies, understood as vertical and Oedipal. In this territory, mothers and old ladies become, as Mary Jacobus memorably phrased it, little more than "the waste products" of a system in which marriageable women are objects of exchange between men (142) and a mother's death would be expected to grease the wheels of narrative. Identity and narrative are inextricably linked here: a certain understanding of narrative as developmental and teleological paves the way for an understanding of identity as either/or. There are problems, however, in trying to read ABCD as a bildüngsroman structured by what Susan Freidman calls "the temporal plots of the family romance, its repetitions and discontents" (137), rendering the "Indian" characteristics of the plot unreadable, and the apparently self-defeating nature of the characters' choices and behavior, rather pointless. A central [End Page 16] difficulty is that the film both responds to and resists readings based on the Oedipal model of the bildüngsroman with its focus on linear development through time.

An optimized mean variance estimation method for uncertainty quantification of wind power forecasts

A statistical optimized technique for rapid development of reliable prediction intervals (PIs) is presented in this study. The mean-variance estimation (MVE) technique is employed here for quantification of uncertainties related with wind power predictions. In this method, two separate neural network models are used for estimation of wind power generation and its variance. A novel PI-based training algorithm is also presented to enhance the performance of the MVE method and improve the quality of PIs. For an in-depth analysis, comprehensive experiments are conducted with seasonal datasets taken from three geographically dispersed wind farms in Australia. Five confidence levels of PIs are between 50% and 90%. Obtained results show while both traditional and optimized PIs are hypothetically valid, the optimized PIs are much more informative than the traditional MVE PIs. The informativeness of these PIs paves the way for their application in trouble-free operation and smooth integration of wind farms into energy systems. © 2014 Elsevier Ltd. All rights reserved.

Does supply always come on the heels of demand? Matches and mismatches in e-learning

Developing sustainable e-learning requires a better understanding of the perceptions and preferences of e-learning providers and e-learners on the four crucial dimensions for elearning success including pedagogies, technologies, learning resources and management of learning resources. There is, however, little research on evaluating whether these critical dimensions are perceived as critical by e-learning providers and e-learners. To address this issue, this study investigates the gap between e-learners’ and e-learning providers’ perceptions and preferences on these critical dimensions for e-learning effectiveness. Such an investigation paves the way for developing appropriate measures to reduce the gap between the supply and the demand for sustainable e-learning.

Inhibition of HIV-1 replication by balsamin, a ribosome inactivating protein of Momordica balsamina

Ribosome-inactivating proteins (RIPs) are endowed with several medicinal properties, including antiviral activity. We demonstrate here that the recently identified type I RIP from Momordica balsamina also possesses antiviral activity, as determined by viral growth curve assays and single-round infection experiments. Importantly, this activity is at play even as doses where the RIP has no cytotoxic effect. In addition, balsamin inhibits HIV-1 replication not only in T cell lines but also in human primary CD4(+) T cells. This antiviral compound exerts its activity at a viral replicative step occurring later than reverse-transcription, most likely on viral protein translation, prior to viral budding and release. Finally, we demonstrate that balsamin antiviral activity is broad since it also impedes influenza virus replication. Altogether our results demonstrate that type I RIP can exert a potent anti-HIV-1 activity which paves the way for new therapeutic avenues for the treatment of viral infections.

Triggering nanoparticle surface ligand rearrangement via external stimuli: light-based actuation of biointerfaces

Bio-molecular non-covalent interactions provide a powerful platform for material-specific self-organization in aqueous media. Here, we introduce a strategy that integrates a synthetic optically-responsive motif with a materials-binding peptide to enable remote actuation. Specifically, we linked a photoswitchable azobenzene moiety to either terminus of a Au-binding peptide. We employed these hybrid molecules as capping agents for synthesis of Au nanoparticles. Integrated experiments and molecular simulations showed that the hybrid molecules maintained both of their functions, i.e. binding to Au and optically-triggered reconfiguration. The azobenzene unit was optically switched reversibly between trans and cis states while adsorbed on the particle surface. Upon switching, the conformation of the peptide component of the molecule also changed. This highlights the interplay between the surface adsorption and conformational switching that will be pivotal to the creation of actuatable nanoparticle bio-interfaces, and paves the way toward multifunctional peptide hybrids that can produce stimuli responsive nanoassemblies.

Identification and topographical characterisation of microbial nanowires in Nostoc punctiforme

Extracellular pili-like structures (PLS) produced by cyanobacteria have been poorly explored. We have done detailed topographical and electrical characterisation of PLS in Nostoc punctiforme PCC 73120 using transmission electron microscopy (TEM) and conductive atomic force microscopy (CAFM). TEM analysis showed that N. punctiforme produces two separate types of PLS differing in their length and diameter. The first type of PLS are 6-7.5 nm in diameter and 0.5-2 µm in length (short/thin PLS) while the second type of PLS are ~20-40 nm in diameter and more than 10 µm long (long/thick PLS). This is the first study to report long/thick PLS in N. punctiforme. Electrical characterisation of these two different PLS by CAFM showed that both are electrically conductive and can act as microbial nanowires. This is the first report to show two distinct PLS and also identifies microbial nanowires in N. punctiforme. This study paves the way for more detailed investigation of N. punctiforme nanowires and their potential role in cell physiology and symbiosis with plants.

Excessive criminal punishment amounts to punishing the innocent : an argument for taking the parsimony principle seriously

Punishing the innocent is incontestably repugnant. Punishing offenders more harshly than is justified is a form of punishing the innocent, yet this practice is commonplace in the United States. This Article sets out a normative argument in favor of less severe penalties for many forms of offenses. There is already an established principle, which limits punishment to the minimum amount of hardship that is required to achieve the objectives of sentencing. The principle is termed “parsimony” and is widely endorsed. Yet, in reality, it is illusory. It has no firm content and in its current form is logically and jurisprudentially incapable of grounding a persuasive argument for more lenient sentences. This Article gives content to the principle of parsimony. It is argued that application of the principle will result in a considerable reduction in the number of offenders who are sentenced to imprisonment and shorter sentences for many offenders who are jailed. The recommendations in this Article will enhance the fairness and transparency of the sentencing system. The argument is especially important at this point in history. The United States is experiencing an incarceration crisis. The principle of parsimony, properly applied, is an important key to ameliorating the incarceration problem. The Article also examines the operation of the parsimony principle in Australia. Unlike sentencing courts in the United States, Australian judges enjoy considerable discretion in sentencing offenders. Despite the vastly different approach to sentencing in Australia, it too is experiencing a considerable increase in the incarceration rate. It emerges that the courts in a tightly regimented sentencing regime (the United States) and a mainly discretionary system (Australia) effectively ignored the parsimony principle. It is not the strictures in the United States that curtail the imposition of parsimonious sentences; rather, it is the absence of a forceful rationale underpinning the principle and a lack of clarity regarding the attainable objectives of sentencing. This Article addresses these shortcomings. In doing so, it paves the way for fundamentally fairer sentencing outcomes in the United States and Australia.
