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.

Orphan DNA: Indigenous samples, ethical biovalue and postcolonial science in Australia

Thousands of blood samples taken from Australia’s indigenous people lie in institutional freezers of the global North, the legacy of a half-century of scientific research. Since those collections were assembled, standards of ethical research practice have changed dramatically, leaving some samples in a state of dormancy. While some European and American collections are still actively used for genetic research, this practice is viewed as unethical by most Australian genetic researchers, who have closer relationships with indigenous Australians and postcolonial politics. For collections to be used ethically, they require a ‘guardian’ who has an ongoing and documented relationship with the donors, so that consent to further studies on samples can be negotiated. This affective and bureaucratic network generates ‘ethical biovalue’ such that a research project can satisfy Australian ethical review. I propose in this article that without ethical biovalue, collections become ‘orphan’ DNA, divorced from a guardian and often difficult to trace to their sources. Such samples are both orphaned and functionally sterile, unable to produce data, scientific articles, knowledge or prestige. This article draws on an ethnographic study of genetic researchers who are working in indigenous communities across Australia. I present tales of researchers’ efforts to generate ethical biovalue and their fears for succession; fears that extend to threats to destroy samples rather than see them orphaned, or worse, fall into the wrong hands. Within these material and affective  networks, indigenous DNA morphs from biological sample to sacred object to political time bomb. 

A day in the life of an early childhood teacher: identifying the confronting issues and challenges that arise

Recent emphasis upon Early Childhood as an educational priority for the Australian Government has resulted in increases in funding, government initiatives, course providers and the introduc- tion of new policies to the sector in order to improve the quality of early childhood education. The study reported here investigated the "reality" of what it means to be an Early Childhood Teacher within this changing context and identified the roles and responsibilities and the associated chal- lenges. A case study involving observation and interviews with five Bachelor qualified Teachers from varied early childhood settings was undertaken in order to gain knowledge about their ex- periences and perspectives on their work. The data were analyzed using a grounded theory ap- proach involving the identification of key themes and issues about the nature of teachers' work. The findings revealed that in their everyday practice teachers played a complex array of roles that required them to contribute far more than just their teaching skills and knowledge. They were expected to concurrently enact the roles of educator, leader, advocate, communicator, counsellor and administrator whilst juggling everyday challenges including a "lack of time", the need for "further support and more resources" and "building successful partnerships with parents".

Kinomatics: a global study into cinema data

This paper describes a creative industries research project that has applied quantitative approaches commonly used in scientific research to the study of international cinema performance. Using film screening data collected over a two year period, this paper discusses analysis of a global dataset using Appadurai's "-scapes" framework. We have identified several of these "-scapes" that help us investigate film industry behaviour. Concentrating on Appadurai's "Technoscape" an investigation into the geographic spread and distribution of a new and emerging technology, High Frame Rate cinema, has been made. HFR films have screened around the world to mixed reviews. Geographic distribution of HFR technologies and change in this distribution has also been uneven.

Prospects of renewable energy in semi-arid region

Continuous usage of fossil fuels and other conventional resources to meet the growing demand has resulted in in-creased energy crisis and greenhouse gas emissions. Hence, it is essential to use renewable energy sources for more reliable, effective, sustainable and pollution free transmission and distribution networks. Therefore, to facilitate large-scale integration of renewable energy in particular wind and solar photovoltaic (PV) energy, this paper presents the feasibility analysis for semi-arid climate and finds the most suitable places in North East region of Victoria for re-newable energy generation. For economic and environmental analysis, Hybrid Optimization Model for Electric Re-newables (HOMER) has used to investigate the prospects of wind and solar energy considering the Net Present Cost (NPC), Cost of Energy (COE) and Renewable fraction (RF). Six locations are selected from North East region of Victo-ria and simulations are performed. From the feasibility analysis, it can be concluded that Mount Hotham is one of the most suitable locations for wind energy generation while Wangaratta is the most suitable location for solar energy generation. Mount Hotham is also the best suitable locations in North East region for hybrid power systems i.e., com-bination of both wind and solar energy generation.

Managing learning evidence using eportfolio

This paper introduces ePortfolio and its use of managing learning evidence in an eLearning environment. The paper uses the outcomes of a recent project sponsored by Deakin University, Australia and examples from IT teaching practice based on CloudDeakin to explore how ePortfolios add value to personalized and reflective models of eLearning. ePortfolios are proved to be an effective tool for discussion, information collection and reflection, and new ways of thinking about learning evidence management.

Analysis of operating environments: A diagnostic model for linking science, society and policy for sustainability

Through analysis of the dynamics between science and decision-making, we argue that diagnosing fit-for purpose approaches to linking science and decision-making may be possible. Such diagnosis should enable identification of appropriate processes, institutions, objects (e.g. tools, information products) and relationships that can facilitate outcomes. We begin the paper by unsettling the traditional constructions that science must distance itself from debates about values and what is at stake, and so from policy making. Then, drawing from mixed methods case studies in coastal South-eastern Australia, we describe how scientific research has had a bearing on decisions affecting society and the environment. These analyses suggest that the willingness and capacity of research organisations, programmes or projects to actively reflect on and participate in the evolution of the 'operating environment' for their research is integral to their ability to inform outcomes through science. © 2014 Elsevier Ltd.

Geometry and geography

This is an extract from an ongoing project: a ficitionalised memoir in poetic fragments connecting personal trauma with the fall-out from the scientific research in the Cold War. It is influenced by Michel Blanchot's The Writing of the Disaster and an ongoing meditation on the poetics of Marguerite Duras and the poetics of awkwardness.
