Holistic inversion of frequency-domain airborne electromagnetic data with minimal prior information

Brodie, Ross,Sambridge, Malcolm Korean Society of Earth and Exploration Geophysici 2009 지구물리와 물리탐사 Vol.12 No.1

The holistic inversion approach for frequency domain airborne electromagnetic data has previously been employed to simultaneously calibrate, process and invert raw frequency-domain data where prior information was available. Analternative formulation has been developed, which is suitable in the case where explicit prior information is not available. It incorporates: a multi-layer vertically-smooth conductivity model; a simplified bias parameterisation; horizontal smoothing with respect to elevation; and cluster computer parallelisation. Without using any prior data, an inversion of 8.0 million data for 3.4 million parameters yields results that are consistent with independently derived calibration parameters, downhole logs and groundwater elevation data. We conclude that the success of the holistic inversion method is not dependent on a sophisticated conceptual model or the direct inclusion of survey-area specific prior information. In addition, acquisition costs could potentially be reduced by employing the holistic approach which largely eliminates the need for high altitude zero-level measurements.

<P>Algae are (mostly) photosynthetic eukaryotes that occupy multiple branches of the tree of life, and are vital for planet function and health. In this review, we highlight a transformative period in studies of the evolution and functioning of this extraordinary group of organisms and their potential for novel applications, wrought by high-throughput ‘omic’ and reverse genetic methods. We cover the origin and diversification of algal groups, explore advances in understanding the link between phenotype and genotype, consider algal sex determination, and review progress in understanding the roots of algal multicellularity. Experimental evolution studies to determine how algae evolve in changing environments are highlighted, as is their potential as production platforms for compounds of commercial interest, such as biofuel precursors, nutraceuticals, or therapeutics.</P> <P><B>Trends</B></P> <P>Application of modern ‘omic and genetic methods has significantly advanced our understanding of the origin, evolution, and metabolic potential of unicellular and multicellular algae, as well as their diverse modes of sexual reproduction.</P> <P>The GreenCut proteins, a conserved gene set in the Viridiplantae, are primarily plastid targeted and have key roles in the function and regulation of photosynthesis, including the maintenance of photosynthetic reaction complexes.</P> <P>Lab evolution experiments demonstrate the strong adaptability of microalgae to environmental changes that are associated with climate change, although it is unclear whether these results will hold in natural ecosystems.</P> <P>The development of algae as ‘cell factories’ promises to allow the production of not only endogenous molecules, but also non-native compounds such as high-value pigments, bulk chemicals, or even therapeutic proteins.</P>

Towards UAV-based bridge inspection systems: a review and an application perspective

Chan, Brodie,Guan, Hong,Jo, Jun,Blumenstein, Michael Techno-Press 2015 Structural monitoring and maintenance Vol.2 No.3

Visual condition inspections remain paramount to assessing the current deterioration status of a bridge and assigning remediation or maintenance tasks so as to ensure the ongoing serviceability of the structure. However, in recent years, there has been an increasing backlog of maintenance activities. Existing research reveals that this is attributable to the labour-intensive, subjective and disruptive nature of the current bridge inspection method. Current processes ultimately require lane closures, traffic guidance schemes and inspection equipment. This not only increases the whole-of-life costs of the bridge, but also increases the risk to the travelling public as issues affecting the structural integrity may go unaddressed. As a tool for bridge condition inspections, Unmanned Aerial Vehicles (UAVs) or, drones, offer considerable potential, allowing a bridge to be visually assessed without the need for inspectors to walk across the deck or utilise under-bridge inspection units. With current inspection processes placing additional strain on the existing bridge maintenance resources, the technology has the potential to significantly reduce the overall inspection costs and disruption caused to the travelling public. In addition to this, the use of automated aerial image capture enables engineers to better understand a situation through the 3D spatial context offered by UAV systems. However, the use of UAV for bridge inspection involves a number of critical issues to be resolved, including stability and accuracy of control, and safety to people. SLAM (Simultaneous Localisation and Mapping) is a technique that could be used by a UAV to build a map of the bridge underneath, while simultaneously determining its location on the constructed map. While there are considerable economic and risk-related benefits created through introducing entirely new ways of inspecting bridges and visualising information, there also remain hindrances to the wider deployment of UAVs. This study is to provide a context for use of UAVs for conducting visual bridge inspections, in addition to addressing the obstacles that are required to be overcome in order for the technology to be integrated into current practice.

We explore the conditions to achieve this success which includes the critical role of the theorizing process. The theorizing process is the core to crafting two seminal contributions. Implications for achieving innovative research that has a scholarly impact concludes the essay.

COUNTRY OF ORIGIN BRANDING: INTEGRATING COLLECTIVE MEANING WITH IDENTITY AND IMAGE

Roderick J. Brodie,Maureen Benson-Rea,Christopher J. Medlin 글로벌지식마케팅경영학회 2014 Global Marketing Conference Vol.2014 No.7

Motivated by an illustrative case study which assesses the strength of the New Zealand wine brand, we develop a framework that provides a contemporary perspective on Country of Origin (COO) branding. The New Zealand wine industry’s COO branding was initially built around the country image of “green” production with the logo “riches of a clean green land”. This has been superseded by a branding strategy that focuses on developing the collective meaning of the COO brand with the logo “pure discovery”. A collective approach to branding involves broader considerations, where the brand is used to facilitate processes that co-create experience and meaning that reflects collective interest. This entails the alignment of a complex set of industry relationships where value is co-created within a network of stakeholders that contribute to the heritage of New Zealand Wine and its quality positioning as the country-of-origin. Our contribution comes from a wider conceptual understanding of COO to show that “COO matters” when a shared identity and image are integrated to form a collective meaning which co-creates value to fulfil the expectations of a brand’s promises of innovation, authenticity and quality.

NEGATIVE ACTOR ENGAGEMENT IN STUDENT LEARNING SYSTEM: CONCEPTUALISATION, SCALE DEVELOPMENT AND VALIDATION

Loic Pengtao Li,Biljana Juric,Roderick Brodie 글로벌지식마케팅경영학회 2018 Global Marketing Conference Vol.2018 No.07

A predominantly positive view is shown in engagement literature in terms of positive actor engagement (PNE) expressions and outcomes. However, business practices indicate that the understanding of actors being negatively engaged is important. Yet a few studies in marketing, which attempt to conceptualise negative actor engagement (NAE), do not have a consensus as for whether NE and PE are reciprocal or NE is a distinct construct with a different nomological network and process. The purpose of this study is to conceptualise and operationalise NAE. Built on Li et al.’s (2018) conceptualisation of actor engagement valence, this paper follows Churchill’s (1979) methods of scale development and operationalises the construct of NAE. By developing and validating a NAE scale in specific online learning servcie platforms, we address this identified literature gap. Specifically, this study derives four NAE dimensions, including annoyance, anxiety, futitlity and failed expectation, which we proceed to validate within a nomological net of conceptual relationships in relation to the engagement behaviours (learning, sharing and endorsing). We conclude with an overview of key managerial and scholarly implications arising from this research. This marks the first study in the marketing discipline to operationalise NAE.
