Margins within margins?: voices Speaking through a study of the provision of an educational program for the children of one Australian show circuit

This paper examines the tactics used by the Showmen's Guild of Australasia in successfully lobbying for the development of a distance education program for their children. The Guild is considered to be a 'marginalized' group, meaning members have less access to wealth, power, and status. Since 1930, members of the Showmen's Guild and their families have traveled from town to town providing agricultural and equestrian shows. Despite the diversity of backgrounds and experiences among people connected with the show circuit, the Guild is highly organized and has been politically active. Informal sanctions have been effective in enforcing group discipline and in presenting the image of a single body of opinion. In addition, investment in sophisticated machinery and technology has resulted in show people having the financial resources to buy homes and have a political voice via more 'normalized channels'. Although members learn early that they are a marginalized group and are perceived as different from the mainstream, the group maintains close ties and often celebrates its difference. Implications for educational program development center on the goals of educational programs designed for disadvantaged groups, and the status of other marginalized groups and their efforts to contest their marginalized status.

Enabling states, capitalising enterprise and confronting the social: issues and implications in researching contemporary social capital and enterprise

A key feature of late capitalism continues to be a complex reworking of previous approaches to the relationship between the state and business. This significant shift in the interplay between the public and private sectors has generated such developments as the privatisation of many services formerly provided by government and the growth of not-for-profit organisations seeking to fill gaps in service provision. These changes are highly significant for every citizen and community member and for all stakeholders. This first chapter in this book encapsulates these complex developments in terms of debates about the enabling imperatives of the contemporary state, the character of the intersection between capital and enterprise, and a timely confrontation of what is understood by “the social” in current discourses, policies and strategies. In presenting this distillation, the authors introduce the subsequent chapters in the book in terms of how each chapter, including this one, contributes new insights to the broader project of eliciting the issues and implications attendant on researching contemporary social capital and social enterprise. This project is crucial if we are to understand the ways in which social capital and social enterprise can work sustainably and transformatively with variously marginalised and vulnerable groups in our societies. It is vital also for understanding the ways that such work is constrained and limited in its effectiveness

Neuronal Cell Model and Methods of Use Thereof

We previously described a novel in vitro model of a non-productive herpes simplex virus type 1 (HSV-1) infection in neurally-differentiated (ND)-PC12 cells that allows for inducible virus replication upon forskolin and heat stress (HS) treatment. In this research, we further characterized the model with respect to HSV-2 strain 333. We found that: (i) ND-PC12 cells are non-permissive to HSV-2 replication; (ii) HSV-2 can establish a quiescent infection, like HSV-1, in ND-PC12 cells with the transient use of acycloguanosine (ACV); however unlike HSV-1, anti-viral conditions are not obligatory to establish and maintain a quiescent state; (iii) the quiescent state is maintained in the presence of Vero cell cocultivation indicating that such cultures are free of infectious virus; and (iv) a high percentage of quiescently infected (QIF)-PC 12 cell cultures (80-100%) produce HSV-2 in response to forskolin and HS (43° C., 3 h) treatment for as long as 4 weeks post infection. These findings indicate that ND-PC12 cells can harbor HSV-2 in a cryptic and non-productive state that is reversible. This model has appealing features for studying gene expression during the establishment, maintenance and reactivation phases of the HSV-2 quiescent state in cell culture.

Neuronal Cell Model and Methods of Use Therefor

The present invention provides, inter alia, a PC12 cell quiescently infected with a neurotropic virus. Preferred quiescently-infected neural cells are those wherein the neurotropic virus is a neurotropic herpes virus. Methods related to these and other materials are also provided

Study of the acoustic signature of UHE neutrino interactions in water and ice

The production of acoustic signals from the interactions of ultra-high energy (UHE) cosmic ray neutrinos in water and ice has been studied. A new computationally fast and efficient method of deriving the signal is presented. This method allows the implementation of up to date parameterisations of acoustic attenuation in sea water and ice that now includes the effects of complex attenuation, where appropriate. The methods presented here have been used to compute and study the properties of the acoustic signals which would be expected from such interactions. A matrix method of parameterising the signals, which includes the expected fluctuations, is also presented. These methods are used to generate the expected signals that would be detected in acoustic UHE neutrino telescopes.Comment: 21 pages and 13 figure

Applying a Dynamic Model of Consumer Choice to Guide Brand Development at Jetstar Airways

This paper describes the use of a marketing science model by Jetstar, a subsidiary of Australia's leading airline, Qantas, to effectively and profitably compete in the low-cost carrier marketplace. We trace the evolution of the Jetstar strategy from a baseline calibration of its initial position, to its efforts to attain price competitiveness and service parity, followed by its highly focused, cost-effective service delivery strategy. We develop a hierarchical model with parameters estimated at the individual level. This allows us to study not only how service design and pricing initiatives shift the perceived performance of Jetstar relative to its competitors but also how the airline can move market preferences toward areas in which it has competitive advantage. The contribution of the research is substantial. The Jetstar market share went from 14.0% to 18.1% during the first five quarterly waves of the research, and profits went from $79 million in 2006-2007, before the study was commissioned, to$124 million in 2008-2009

Building better Sex Robots: Lessons from Feminist Pornography

How should we react to the development of sexbot technology? Taking their cue from anti-porn feminism, several academic critics lament the development of sexbot technology, arguing that it objectifies and subordinates women, is likely to promote misogynistic attitudes toward sex, and may need to be banned or restricted. In this chapter I argue for an alternative response. Taking my cue from the sex positive ‘feminist porn’ movement, I argue that the best response to the development of ‘bad’ sexbots is to make better ones. This will require changes to the content, process and context of sexbot development. Doing so will acknowledge the valuable role that technology can play in human sexuality, and allow us to challenge gendered norms and assumptions about male and female sexual desire. This will not be a panacea to the social problems that could arise from sexbot development, but it offers a more realistic and hopeful vision for the future of this technology in a pluralistic and progressive society

Efficacy and mechanistic insights into endocrine disruptor degradation using atmospheric air plasma

Endocrine disruptors are a class of contaminants found in water and process effluents at low concentrations. They are of concern due to their high estrogenic potency. Their presence in the environment has led to the search for effective techniques for their removal in wastewater. For this purpose, an atmospheric air plasma reactor was employed for the study of the degradation of three endocrine disruptor chemicals (EDC) namely; bisphenol A (BPA), estrone (E1) and 17β-estradiol (E2) within a model dairy effluent. Identification of the plasma induced active species both in the gas and liquid phases were performed. Also studied was the influence of an inhibitor, namely tertiary butanol, on the degradation of the EDCs. The results demonstrate that air plasma could successfully degrade the tested EDCs, achieving efficacies of 93% (k=0.189min−1) for BPA, 83% (k=0.132min−1) for E1 and 86% (k=0.149min−1) for E2, with the process following first order kinetics. The removal efficacy was reduced in the presence of a radical scavenger confirming the key role of oxygen radicals such as OH in the degradation process. The intermediate and final products generated in the degradation process were identified using UHPLC-MS and LC-MS. Based on the intermediates identified a proposed degradation pathway is presented
