Wicked Tools: The Value Of Scientific Models For Solving Maine’S Wicked Problems, Tim Waring Nov 2013

Wicked Tools: The Value Of Scientific Models For Solving Maine’S Wicked Problems, Tim Waring

Timothy M Waring

“Wicked problems” are urgent, high-stake socioeconomic-environmental challenges that often involve ideological conflict and have no “best solutions.” Using examples from Maine’s Sustainability Solutions Initiative projects, Tim Waring describes how scientific models can be used to address these kinds of problems. When well-constructed and tested models are used to address policy-relevant issues, include input from stakeholders, and integrate social, economic and environmental dynamics, they can become “wicked tools” to address some of society’s biggest challenges.


Valuing Water: Variability And The Lake Eyre Basin, Central Australia, Leah Gibbs Sep 2013

Valuing Water: Variability And The Lake Eyre Basin, Central Australia, Leah Gibbs

Leah Maree Gibbs

'Environmental values' form an increasingly important component of natural resource management, but use of the term 'value' is dominated by a narrow and limiting utility-based definition. In this paper I consider theories of value and practices of valuing water in the arid and semi-arid Lake Eyre Basin, central Australia. While value is the subject of diverse meanings - both within a range of academic disciplines and as understood by people in specific places - methods of valuing water in natural resource management are limited by reductionism, anthropocentrism and cultural specificity. This conceptualisation of value does not adequately capture what people …


Parcel Subdivision Automation For Agent-Based Land Use Modelling, Rohan Wickramasuriya, Laurie Chisholm, Marji Puotinen, Nicholas Gill, Peter Klepeis Sep 2013

Parcel Subdivision Automation For Agent-Based Land Use Modelling, Rohan Wickramasuriya, Laurie Chisholm, Marji Puotinen, Nicholas Gill, Peter Klepeis

Rohan Wickramasuriya, Ph.D.

To a significant extent rural Australia is transforming into multifunctional landscapes. Amenity migration (i.e. movement of people from metropolitan to rural settings) is a major driving force of this transition in many areas. However, the effects of amenity migration on the receiving landscapes are not yet fully understood. Agent-based land use modelling helps unravel the complex spatio-temporal relationships that affect landscape response to change from amenity migration. A land subdivision module is essential for a complete agent-based land use model developed for these landscapes because the land sold to in-migrants are lots that are subdivided from much larger tracts. In …

Late Quaternary Aeolian And Fluvial Interactions On The Cooper Creek Fan And The Association Between Linear And Source-Bordering Dunes, Strzelecki Desert, Australia, Timothy Cohen, Gerald Nanson, Joshua Larsen, B. Jones, David Price, Maria Coleman, Tim Pietsch Jun 2013

Late Quaternary Aeolian And Fluvial Interactions On The Cooper Creek Fan And The Association Between Linear And Source-Bordering Dunes, Strzelecki Desert, Australia, Timothy Cohen, Gerald Nanson, Joshua Larsen, B. Jones, David Price, Maria Coleman, Tim Pietsch

B. G. Jones

The Innamincka Dome and associated low-gradient fan in the Strzelecki Desert is the product of Cenozoic crustal warping that has aided formation of an extensive array of palaeochannels, source-bordering transverse dunes and superimposed linear dunes. These dunes have impeded the course of Cooper Creek and provided a repository of evidence for Quaternary climate change as well as the interactive processes between transverse and linear dune formation. At Turra, Gidgealpa and sites nearby are extensive fluvial and aeolian sand bodies that date from marine isotope stages (MIS) 8-3 and the Last Glacial Maximum (LGM) and are now surrounded or buried by …


Automated Extraction Of Community Mobility Measures From Gps Stream Data Using Temporal Dbscan, Sungsoon Hwang, Timothy Hanke, Christian Evans May 2013

Automated Extraction Of Community Mobility Measures From Gps Stream Data Using Temporal Dbscan, Sungsoon Hwang, Timothy Hanke, Christian Evans

Sungsoon Hwang

Inferring community mobility of patients from GPS data has received much attention in health research. Developing robust mobility (or physical activity) monitoring systems relies on the automated algorithm that classifies GPS track points into events (such as stops where activities are conducted, and routes taken) accurately. This paper describes the method that automatically extracts community mobility measures from GPS track data. The method uses temporal DBSCAN in classifying track points, and temporal filtering in removing noises (any misclassified track points). The result shows that the proposed method classifies track points with 88% accuracy. The percent of misclassified track points decreased …


Structural Characterization Of Clusterin-Chaperone Client Protein Complexes, Amy Wyatt, Justin Yerbury, Mark Wilson May 2013

Structural Characterization Of Clusterin-Chaperone Client Protein Complexes, Amy Wyatt, Justin Yerbury, Mark Wilson

Mark R Wilson

Clusterin (CLU) is a potent extracellular chaperone that inhibits protein aggregation and precipitation otherwise caused by physical or chemical stresses (e.g. heat, reduction). This action involves CLU forming soluble high molecular weight (HMW) complexes with the client protein. Other than their unquantified large size, the physical characteristics of these complexes were previously unknown. In this study, HMW CLU-citrate synthase (CS), HMW CLU-fibrinogen (FGN), and HMW CLU-glutathione S-transferase (GST) complexes were generated in vitro, and their structures studied using size exclusion chromatography (SEC), ELISA, SDS-PAGE, dynamic light scattering (DLS), bisANS fluorescence, and circular dichroism spectrophotometry (CD). Densitometry of …


Communication: New Insight Into The Barrier Governing Co2 Formation From Oh + Co, Christopher Johnson, Berwyck Poad, Ben Shen, Robert Continetti May 2013

Communication: New Insight Into The Barrier Governing Co2 Formation From Oh + Co, Christopher Johnson, Berwyck Poad, Ben Shen, Robert Continetti

Berwyck L. J. Poad

Despite its relative simplicity, the role of tunneling in the reaction OH + CO → H + CO(2) has eluded the quantitative predictive powers of theoretical reaction dynamics. In this study a one-dimensional effective barrier to the formation of H + CO(2) from the HOCO intermediate is directly extracted from dissociative photodetachment experiments on HOCO and DOCO. Comparison of this barrier to a computed minimum-energy barrier shows that tunneling deviates significantly from the calculated minimum-energy pathway, predicting product internal energy distributions that match those found in the experiment and tunneling lifetimes short enough to contribute significantly to the overall reaction. …


Optically Stimulated Luminescence (Osl) Dating Of Perenially Frozen Deposits In North-Central Siberia: Osl Characteristics Of Quartz Grains And Methodological Considerations Regarding Their Suitability For Dating, Lee Arnold, Richard Roberts Mar 2013

Optically Stimulated Luminescence (Osl) Dating Of Perenially Frozen Deposits In North-Central Siberia: Osl Characteristics Of Quartz Grains And Methodological Considerations Regarding Their Suitability For Dating, Lee Arnold, Richard Roberts

Richard G Roberts

Optically stimulated luminescence (OSL) dating of coarse-grained quartz is increasingly being used as the main chronological tool in late Quaternary palaeoenvironmental reconstructions of Siberia. However, relatively little information has been published on the suitability of OSL dating for the various types of perennially frozen sediments found in this region. Here we provide a systematic examination of the quartz luminescence characteristics of 21 perennially frozen samples from the Taimyr Peninsula and adjacent coastal lowlands of north-central Siberia, and discuss their implications for the reliability of single-grain and multi-grain OSL chronologies in such contexts. The results of this study suggest that the …


Development Of The Sar Tt-Osl Procedure For Dating Middle Pleistocene Dune And Shallow Marine Deposits Along The Southern Cape Coast Of South Africa, Zenobia Jacobs, Richard Roberts, Terry Lachlan, Panagiotis Karkanas, Curtis Marean, David Roberts Mar 2013

Development Of The Sar Tt-Osl Procedure For Dating Middle Pleistocene Dune And Shallow Marine Deposits Along The Southern Cape Coast Of South Africa, Zenobia Jacobs, Richard Roberts, Terry Lachlan, Panagiotis Karkanas, Curtis Marean, David Roberts

Richard G Roberts

Optically stimulated luminescence (OSL) dating is now commonly used to estimate the depositional age of Quaternary landforms along the southern Cape coast of South Africa. Due to the early onset of dose saturation in the quartz-rich sediments from this region, determining the age of deposits much older than the last three glacio-eustatic sea-level high stands has been a challenge. In this study, we explored the feasibility of using the thermally-transferred OSL (TT-OSL) dating method to obtain ages for aeolian and shallow marine deposits at three different localities that hold promise to further illuminate the long and complex Late Quaternary sea-level …

Dirt, Dates And Dna:Osl And Radiocarbon Chronologies Of Perenially Frozen Sediments In Siberia, And Their Implications For Sedimentary Ancient Dna Studies, Lee Arnold, Richard Roberts, Ross Macphee, James Haile, Fiona Brock, Per Moller, Duane Froese, Alexei Tikhonov, Allan Chivas, M. Thomas Gilbert, Eske Willerslev

Richard G Roberts

The sedimentary ancient DNA (sedaDNA) technique offers a potentially invaluable means of investigating species evolution and extinction dynamics in high-latitude environments. An implicit assumption of the sedaDNA approach is that the extracted DNA is autochthonous with the host deposit and that it has not been physically transported from older source deposits or reworked within the sedimentary profile by postdepositional mixing. In this paper we investigate whether these fundamental conditions are upheld at seven perennially frozen wetland sites across the Taimyr Peninsula and coastal lowlands of north-central Siberia. Optically stimulated luminescence (OSL) and radiocarbon (14C) dating are used to constrain the …


Late Acheulean Hominins At The Marine Isotope Stage 6/5e Transition In North-Central India, Michael Haslam, Richard Roberts, Ceri Shipton, J Pal, Jacqueline Fenwick, Peter Ditchfield, Nicole Boivin, A Dubey, M Gupta, Michael Petraglia Mar 2013

Late Acheulean Hominins At The Marine Isotope Stage 6/5e Transition In North-Central India, Michael Haslam, Richard Roberts, Ceri Shipton, J Pal, Jacqueline Fenwick, Peter Ditchfield, Nicole Boivin, A Dubey, M Gupta, Michael Petraglia

Richard G Roberts

Single-grain optically stimulated luminescence dating was applied to Late Quaternary sediments at two sites in the Middle Son Valley, Madhya Pradesh, India. Designated Bamburi 1 and Patpara, thesse sites contain Late Acheulean stone tool assemblages, which we associate with non-modern hominins. Age determinations of 140-120. ka place the formation of these sites at around the Marine Oxygen Isotope Stage 6-5 transition, placing them among the youngest Acheulean sites in the world. We present here the geochronology and sedimentological setting of these sites, and consider potential implications of Late Pleistocene archaic habitation in north-central India for the initial dispersal of modern …


Mapping Same-Sex Couple Family Households In Australia, Andrew Gorman-Murray, Christopher Brennan-Horley, Kirsten Mclean, Gordon Waitt, Christopher Gibson Jan 2013

Mapping Same-Sex Couple Family Households In Australia, Andrew Gorman-Murray, Christopher Brennan-Horley, Kirsten Mclean, Gordon Waitt, Christopher Gibson

Christopher R Brennan-Horley

The map (1:1,218,987) accompanying this report is the first to depict the distribution of same-sex couple family households across Australia. The map and the report contribute to emerging scholarship combining critical geographies of sexualities with quantitative techniques and GIS in order to advance the political claims of sexual minorities. The data were collected through the 2006 Census and obtained via consultation with the Australian Bureau of Statistics. These data included the number of same-sex couple family households for all Statistical Divisions across Australia and for Statistical Sub-Divisions within metropolitan capital cities. Geographical concentrations of same-sex couple family households were determined …

Here, I present a series of shell analyses that can assist in the investigation of several research issues, focusing primarily on ecological issues.


Defining Adequate Means Of Residents To Prepare Property For Protection From Wildfire, Trent Penman, Christine Eriksen, R Blanchi, M Chladil, A Gill, K Haynes, Justin Leonard, Jim Mclennan, Ross Bradstock Dec 2012

Defining Adequate Means Of Residents To Prepare Property For Protection From Wildfire, Trent Penman, Christine Eriksen, R Blanchi, M Chladil, A Gill, K Haynes, Justin Leonard, Jim Mclennan, Ross Bradstock

Christine Eriksen

Wildfire can result in significant loss of property and lives. Evidence shows that residents can decrease the risk of loss when they stay to defend their property. In order to safely defend a property, residents need to be adequately prepared for the wildfire conditions they face. Residents who wish to evacuate prior to the arrival of a wildfire also need to prepare their property and themselves for such an action. Despite the importance of preparation, there are no clear and quantifiable definitions of what it means to be prepared for different exposures to wildfire. Here we develop a model and …


Time Series, Unit Roots, And Cointegration: An Introduction, Lonnie K. Stevans Dec 2012

Time Series, Unit Roots, And Cointegration: An Introduction, Lonnie K. Stevans

Lonnie K. Stevans

The econometric literature on unit roots took off after the publication of the paper by Nelson and Plosser (1982) that argued that most macroeconomic series have unit roots and that this is important for the analysis of macroeconomic policy. Yule (1926) suggested that regressions based on trending time series data can be spurious. This problem of spurious correlation was further pursued by Granger and Newbold (1974) and this also led to the development of the concept of cointegration (lack of cointegration implies spurious regression). The pathbreaking paper by Granger (1981), first presented at a conference at the University of Florida …


Kernel Density Estimation Of Traffic Accidents In A Network Space, Zhixiao Xie, Jun Yan Dec 2012

Kernel Density Estimation Of Traffic Accidents In A Network Space, Zhixiao Xie, Jun Yan

Dr Jun Yan

A standard planar Kernel Density Estimation (KDE) aims to produce a smooth density surface of spatial point events over a 2-D geographic space. However, the planar KDE may not be suited for characterizing certain point events, such as traffic accidents, which usually occur inside a 1-D linear space, the roadway network. This paper presents a novel network KDE approach to estimating the density of such spatial point events. One key feature of the new approach is that the network space is represented with basic linear units of equal network length, termed lixel (linear pixel), and related network topology. The use …


Mindscapes And Landscapes: Hayek And Simon On Cognitive Extension, Leslie Marsh Oct 2012

Mindscapes And Landscapes: Hayek And Simon On Cognitive Extension, Leslie Marsh

Leslie Marsh

Hayek’s and Simon’s social externalism runs on a shared presupposition: mind is constrained in its computational capacity to detect, harvest, and assimilate “data” generated by the infinitely fine-grained and perpetually dynamic characteristic of experience in complex social environments. For Hayek, mind and sociality are co-evolved spontaneous orders, allowing little or no prospect of comprehensive explanation, trapped in a hermeneutically sealed, i.e. inescapably context bound, eco-system. For Simon, it is the simplicity of mind that is the bottleneck, overwhelmed by the ambient complexity of the environmental. Since on Simon’s account complexity is unidirectional, Simon is far more ebullient about the prospects …


Adaptation To Hard-Object Feeding In Sea Otters And Hominins, Paul Constantino, James Lee, Dylan Morris, Peter Lucas, Adam Hartstone-Rose, Wah-Keat Lee, Nathaniel Dominy, Andrew Cunningham, Mark Wagner, Brian Lawn Sep 2012

Adaptation To Hard-Object Feeding In Sea Otters And Hominins, Paul Constantino, James Lee, Dylan Morris, Peter Lucas, Adam Hartstone-Rose, Wah-Keat Lee, Nathaniel Dominy, Andrew Cunningham, Mark Wagner, Brian Lawn

Paul J. Constantino

The large, bunodont postcanine teeth in living sea otters (Enhydra lutris) have been likened to those of certain fossil hominins, particularly the ’robust’ australopiths (genus Paranthropus). We examine this evolutionary convergence by conducting fracture experiments on extracted molar teeth of sea otters and modern humans (Homo sapiens) to determine how load-bearing capacity relates to tooth morphology and enamel material properties. In situ optical microscopy and x-ray imaging during simulated occlusal loading reveal the nature of the fracture patterns. Explicit fracture relations are used to analyze the data and to extrapolate the results from humans to earlier hominins. It is shown …


Approaches To Development Of A User-Friendly Community Based Arsenic/Iron Removal Unit In Bangladesh, Khondoker Mahabub Hassan, Farooque Ahmed, Faisal Hai, Saleh Faraj Magram Aug 2012

Approaches To Development Of A User-Friendly Community Based Arsenic/Iron Removal Unit In Bangladesh, Khondoker Mahabub Hassan, Farooque Ahmed, Faisal Hai, Saleh Faraj Magram

Faisal I Hai

The present stydy focuses on the strategies to modify the design of a community based Arsenic - Iron Removal Unit (AIRU) based on the field performance of the AIRU and the feedback from the users. The ultimate aim was to offer a user-friendly and sustainable system. Appropriate modifications in the design of the developed unit reduced the propensities of water head-loss and media clogging, thereby yielding sustained flow rate. Introduction of a simple cleaning procerdure (98% flow-recovery with three successive backwashing sequences) successfully reduced the frequency of requirement of labor-intensive replacement of the whole filter media. Raw water with arsenic …


Manufacturing On The Move? Beyond The High Dollar In The Debate About Making Things In Australia - The Case Of The Australian Surfboard Industry - Ausccer Discussion Paper No. 2012/2, Andrew Warren, Chris Gibson Jul 2012

Manufacturing On The Move? Beyond The High Dollar In The Debate About Making Things In Australia - The Case Of The Australian Surfboard Industry - Ausccer Discussion Paper No. 2012/2, Andrew Warren, Chris Gibson

Chris Gibson

In October 2011 surfboard manufacturer BASE abruptly closed its factory on the Gold Coast resulting in the direct loss of 50 jobs. A few days later, nearby D’Arcy Surfboards also announced it was shedding workers and downsizing from a state-of-the art purpose built factory into a backyard workshop. Each business exported surfboards internationally and employed some of Australia’s best known surfboard-makers. The troubles facing these workshops added to those brewing at the very same in Australia’s steel, aluminium, automotive and garment industries. With renewed public debate and media commentary on the future of manufacturing, we now face a crisis in …

Statistical Methods Used In Gifted Education Journals, 2006-2010, Russell Warne, Maria Lazo, Tami Ramos, Nicola Ritter Jun 2012

Statistical Methods Used In Gifted Education Journals, 2006-2010, Russell Warne, Maria Lazo, Tami Ramos, Nicola Ritter

Russell T Warne

This article describes the statistical methods used in quantitative and mixed methods articles between 2006 and 2010 in five gifted education research journals. Results indicate that the most commonly used statistical methods are means (85.9% of articles), standard deviations (77.8%), Pearson’s r (47.8%), χ2 (32.2%), ANOVA (30.7%), t tests (30.0%), and MANOVA (23.0%). Approximately half (53.3%) of the articles included reliability reports for the data at hand; Cronbach’s alpha was the most commonly reported measure of reliability (41.5%). Some discussions of best statistical practice and implications for the field of gifted education are included.


Arctic To Outback: Indigenous Rights, Conservation And Tourism, Michael Adams Jun 2012

Arctic To Outback: Indigenous Rights, Conservation And Tourism, Michael Adams

Michael Adams

Internationally, there has been significant growth in conservation landscapes as a land tenure, since the specific creation of the concept of a “national park” at Yellowstone, USA, in 1872. “Protected areas”, as an umbrella designation for national parks, nature reserves and other forms of conservation landscape, now occupy nearly 13% of the world’s terrestrial area (Chape, Spalding and Jenkins 2008). The early North American, Australian and many other national park systems, while focusing on conservation, explicitly embraced tourism (Boyd and Butler, 2000). However, in the decades since World War II, recreational use of national parks has increased enormously, creating entire …

Bushfire And Everyday Life: Examining The Awareness-Action 'Gap' In Changing Rural Landscapes, Christine Eriksen, Nicholas Gill Jun 2012

Bushfire And Everyday Life: Examining The Awareness-Action 'Gap' In Changing Rural Landscapes, Christine Eriksen, Nicholas Gill

Christine Eriksen

In this paper we use the notion of 'everyday life' to critically examine an apparent 'gap' between bushfire risk awareness and preparedness amongst diverse landholders in rural landscapes affected by amenity-led in-migration in southeast Australia. Landholders were found to bring their own agency to bushfire preparedness in the relationships between everyday procedures, dilemmas, and tradeoffs. Consequently, regardless of landholders' awareness levels, attitudes towards bushfire and natural resource management influence if, how, and to what extent landowners prepare for bushfires. We argue that not only is the 'gap' complex but also paradoxical in that it is both evident in, and constituted …
