Terrain characteristics influencing aquifer salinisation of the Glenelg-Hopkins CMA region, using GIS

Salinisation of aquifers is an issue of great concern in the Glenelg-Hopkins region. The GlenelgHopkins region is located in south-west Victoria, south of the Great Dividing Range and covers 2.6 million hectares. The area receives an annual average rainfall of 500-910 mm and experiences a Mediterranean climate, with hot, dry summers and cold wet winters and has varied geology and soil types. Terrain characteristics, such as soil type, geology, depth-to-water table, land use and topography have been integrated into a Geographic Information System (GIS). A geostatistical approach, including the use of multiple linear regression is used to analyse the spatial variability of the relationships between aquifer salinity and terrain characteristics across the entire region. Results from this study should greatly improve knowledge of aquifer salinisation across the region. It is expected that this work will enable managers to determine the most appropriate mitigating measures for each specific area affected.

Contested terrain: Point Nepean, Victoria

It is within the power of place to encompass many meanings, stories, and memories. Point Nepean has always been a contested landscape. But over recent years this 'land' has been the subject of intense debate as its future status is renegotiated. Evidence overwhelmingly suggests that Point Nepean should be recognised again as a unique and inviolable whole, in spite of the Commonwealth Government's division of the land into three parcels. It has always been my contention that all decisions relating to Point Nepean should be made with a clear understanding and appreciation of the natural and cultural significance of the whole area, in the broader context of 'place', such that place governs the approach and decision-making process. It is therefore necessary to not only establish that natural and cultural heritage is inextricably linked, but that it must be approached in an integrated manner.

Visual terrain analysis of high-dimensional datasets

Most real-world datasets are, to a certain degree, skewed. When considered that they are also large, they become the pinnacle challenge in data analysis. More importantly, we cannot ignore such datasets as they arise frequently in a wide variety of applications. Regardless of the analytic, it is often that the effectiveness of analysis can be improved if the characteristic of the dataset is known in advance. In this paper, we propose a novel technique to preprocess such datasets to obtain this insight. Our work is inspired by the resonance phenomenon, where similar objects resonate to a given response function. The key analytic result of our work is the data terrain, which shows properties of the dataset to enable effective and efficient analysis. We demonstrated our work in the context of various real-world problems. In doing so, we establish it as the tool for preprocessing data before applying computationally expensive algorithms.

Unspeakable terrain : visualising ontological terror in performance

This paper presented at the 2010 ADSA Conference held at the Australian National University draws upon my practice based research submitted for a Master of Animateuring (Cross Modal Performance) at the faculty of the Victorian College of the Arts- Melbourne University. Aviary which premiered at the Living Museum of the West in 2006 (a visual space-specific performance during which only one word was uttered) was used as an exemplar of my practice revealing how ontological terror can only be artistically represented through carefully chosen veils, two of which can be made explicit through an analysis of the aesthetic conventions of the liminal uncanny and the traumatic sublime.

A procedural, minimal input, natural terrain plug-in for Blender

This project uses methods of terrain representation, creation and realism described in literature. We find that using a combination of Fractional Brownian Motion and procedural formation of rivers via squig curves to form initial terrain, with hydraulic erosion for post processing, we have full control over the style of terrain: from jagged mountains to flat regions; and the phase of river from tightly rock controlled to flood plain regions.

Navigating the terrain of lived experiences: the value of lifeworld existentials for reflective analysis

In qualitative research we are often presented with a tension between having open and fluid interviews to support staying true to the lived experiences of participants and achieving a level of abstraction from the data in order to uncover the essential structures and meanings of that particular lived experience. A way of resolving this tension is through the application of theoretical frameworks. Van Manen’s four lifeworld existentials offer a lens through which to explore and navigate disparate interview data and uncover the essences of lived experience, without imposing categories upon the data itself. Drawing on a study exploring the lived experiences of childless women, we explore the process and principles in operationalising the existentials and discuss the potential implications for analysis and findings. The article demonstrates how Van Manen’s lifeworld existentials present us with a holistic and valuable method for reflective practice, in coming to understand lived experience.

Navigating teacher education: mapping the terrain, surveying the landscape

While there are many small-scale case studies that investigate specific teacher education practices, large scale longitudinal studies designed to provide rich and comprehensive data about the effectiveness of teacher education, are limited (Cochran-Smith & Zeichner, 2005). The Studying the Effectiveness of Teacher Education (SETE) project aims to address this gap by investigating the effectiveness of teacher education programs in preparing teachers for the variety of school settings in which they begin their careers. This three-year study utilises large-scale surveys and case studies, and includes a comprehensive mapping of teacher education programs across Australia. It tracks all 2010/2011 teacher education graduates in Queensland and Victoria to investigate the effectiveness of particular characteristics of their teacher education programs in equipping them with the capacity to meet the learning needs of young people in a diverse range of Australian school settings.

This paper presents the findings from the mapping exercise and the surveys of teachers and principals, and the problematics and possibilities of reading across the data sets. The SETE mapping exercise used publicly available online information to examine the characteristics of initial teacher education programs accredited by the Victorian Institute of Teaching (VIT) and the Queensland College of Teachers (QCT). Preliminary results address, inter alia, the length, content and delivery of programs and critical issues of the development of pedagogical and assessment expertise and preparation to teach in diverse contexts. The paper also presents findings from the first of a series of online surveys completed by teacher education graduates in Queensland and Victoria. Beginning teachers’ responses are mapped against key characteristics of participants' pre-service programs and framed in relation to the key themes of curriculum, pedagogy, assessment, behaviour management, and engagement with school stakeholders and local community.

Imagined terrain: literary nomadism in Venice and the Veneto

Many poets and writers have used Venice and, to a lesser extent, the Veneto as a creative topos. There is both the writing that might be said to belong to the Italian/Venetian literary tradition, as well as the non-Italian tradition of writing Venice, a phenomenon that spans English literature, in particular, from William Shakespeare’s time, to the Romantic period and into the present day. This paper explores my relationship to this creative topos and the writers and writing that are associated with it. In particular, it focuses on the notion of literary nomadism: a method for interacting with the literature of Venice and the Veneto that allows me to find intersections between my own work and that which already exists in a broad historical and literary terrain. Moving between and across the literatures of this region, I argue that it is possible to find multiple points of reference that guide and inform my own poetic responses to it, and which reflect my own subjective nomadism and in-between-ness. By taking such an approach I am able to map my hybrid, transnational and transcultural identity into this space, in order to locate myself—and my writing—in the ‘imagined terrain’ I have chosen as a creative topos.

Evaluating temporal changes in hydraulic conductivities near karst-terrain dams: Dokan Dam (Kurdistan-Iraq)

Dam sites provide an outstanding opportunity to explore dynamic changes in the groundwater flow regime because of the high hydraulic gradient rapidly induced in their surroundings. This paper investigates the temporal changes of the hydraulic conductivities of the rocks and engineered structures via a thorough analysis of hydrological data collected at the Dokam Dam, Iraq, and a numerical model that simulates the Darcian component of the seepage. Analysis of the data indicates increased seepage with time and suggests that the hydraulic conductivity of the rocks increased as the conductivity of the grout curtain decreased. Conductivity changes on the order of 10-8m/s, in a 20-yr period were quantified using the numerical analysis. It is postulated that the changes in hydraulic properties in the vicinity of Dokan Dam are due to suspension of fine materials, interbedded in small fissures in the rocks, and re-settlement of these materials along the curtain. Consequently, the importance of the grout curtain to minimize the downstream seepage, not only as a result of the conductivity contrast with the rocks, but also as a barrier to suspended clay sediments, is demonstrated. The numerical analysis also helped us to estimate the proportion of the disconnected karstic conduit flow to the overall flow.

Power to the virtuous? Civic culture in the changing digital terrain

Much scholarship laments a decline in civic participation and community social capital in a changing media world. But the concept of “civicness” remains important to functioning societies across the globe. This research borrows from the cultural turn in studies of media, communication and citizenship to examine civic as culture, anchored in the practices and symbolic milieu of everyday life. As its theoretical entry point, this research paper positions civic as virtue. Drawing on scholars from Aristotle to Pierre Bourdieu, civic virtue may be understood as a perceived moral obligation to serve the common good, especially the interests of a “community” in which individuals and/or groups are connected. In particular, the research extends Bourdieu's ideas to consider news media as a powerful institution alongside the state that may claim monopoly over the manipulation of civic virtue under certain social conditions. Civic virtue offers much in discussions about media power in the digital age and its relationship to the future viability and legitimacy of news media. The research draws on exemplars from a study into digitally mediated civic participation in a rural/regional Australian context to position certain local media as “keepers” and “conferrers” of civic virtue in the social settings they serve.
