    Conference poster
    The University of Auckland Library

    Our existing Voyager catalogue tutorial was text-heavy and decontextualised— detached from student experience, youth culture and the research process. The aim was to create a student-centred tutorial, applying sound learning principles, providing relevant contexts for first year students and using Net Gen modes to convey the information.

  • Bronchoconstriction and the MBNW: Insights from anatomical lung modelling.

    Mitchell, Jennine; Tawahi MH (2010-11-30)

    Conference poster

    Bronchoconstriction and the MBNW: Insights from anatomical lung modelling. Jennine Mitchell and Dr Merryn Tawhai Auckland Bioengineering institute The multiple breath nitrogen washout (MBNW) is a global test of lung function that produces two indices Sacin and Scond that are reflective of ventilation heterogeneity arising at the level of acinus and between more spatially disparate regions of the lung respectively. An important application of the MBNW is in the study of asthma. Ventilation defects have been noted to occur in imaging studies of asthma. These regional ventilation defects have not previously been considered in relation to the MBNW indices. Scond is purported to be related to the state of conducting airways however no modelling studies exist which directly link the airway state to Scond. In this work regional ventilation defects have been simulated in an anatomically based human lung model and theoretically linked to the MBNW indices Sacin and Scond. Ventilation is simualted to the level of the acinus in a model in which acinar ventilation is considered independent of ventialtion in other acini. As previously indicated in modelling studies a high degree of constriction is required to produce a ventilation defect. The relationship between the degree of constriction in airways leading to the defect and the Scond index is however highly non-linear and shows a sharp decrease at very high levels of constriction. Ventilation defects potentially cause non-communication of gas trapped in the ventilation defects with the mouth. This may alter the calculation of FRC if nitrogen dilution is used to calculate FRC. As the indices are dependent on the phase III slope for each breath being normalised by FRC this alters MBNW results. The index Scond is not be able to be explained simply in terms of increased time constants due to increased resistance in the main conducting airway tree. The model indicates that the Scond index is more complex than current MBNW theory indicates and cannot be simply explained in terms of a longer time constant due to constriction in the conducting airway tree resulting in increased late emptying of poorly ventilated regions.

    Conference poster
    The University of Auckland Library

    Conference Details: ICONIP 2008 - 15th International Conference on Neural Information. Processing of the Asia-Pacific Neural Network Assembly November 25-28, 2008, Auckland, New Zealand We are interested in clustering sets of highly overlapping clusters. For example, given is an observed set of stars (considered to be a set of points); how to find (recover) clusters which are the contributing galaxies of the observed union of those clusters? Below we propose a modification of an adaptive mean shift-based clustering algorithm (called Algorithm 1) proposed in 2003 by B. Geogescu, I. Shimsoni and P. Meer

  • Institutional Collaboration around Institutional Repositories

    Hayes, Leonie; Stevenson, Alison; Mason, Ingrid; Scott, Anne; Kennedy, Peter (2007)

    Conference poster
    The University of Auckland Library

    Three New Zealand universities have been collaborating on a project to provide open, web-based, access to research outputs through the creation of institutional repositories using the DSpace software. This poster will therefore address the theme of eResearch with particular focus on the benefits of active collaboration, intra-university, inter-university and international, in this area of activity. New Zealand has a small population of 4 million, an innovative and resourceful academic community, a newly implemented research funding model, based on performance (PBRF) and a readiness to stay competitive with the rest of the world. Institutional Repositories in New Zealand are in their infancy but a considerable body of experience already exists overseas which we can draw upon if we work in partnership with those institutions who have already implemented institutional repositories. Funding is limited but by sharing resources and working collaboratively each institution can make substantial progress towards the creation of individual repositories. This poster reports on the joint project between the University of Auckland, the University of Canterbury and Victoria University of Wellington. The three partners have been funded by the New Zealand Tertiary Education Commission to make available, via the Internet for access by Open Archives Initiative (OAI) compliant search engines, research outputs created by staff and students of the three partner institutions. This poster will present information on the work to: • Establish DSpace repositories in partner institutions that conform to the OAI-PMH standard. • Contribute to the development of linkages with the Australian DEST funded information infrastructure projects, i.e. ADT, APSR and ARROW projects. • Identify methods for increasing academic understanding of, and promoting contributions to, digital repositories the content of which is then available to enhance teaching and learning, as well as research. • Provide digital materials, either through the deposit of “born digital” material or through digitisation of material already available in print, that contribute to the developing digital content landscape as envisaged in the NZ Digital Strategy • Contribute to national research resource discovery service to be established by the National Library of New Zealand. Ensure that the content in the project repositories is visible for harvesting by global OAI-compliant search engines such as Google Scholar, OAIster, etc. Collaborate with other IR projects and communicate the lessons learned to the wider tertiary and research communities of New Zealand

  • CellML: Cellml.org, Tools and Community

    Lawson J.; Lloyd C.; Noble P.; Hunter P.; Nielsen P. (2007)

    Conference poster
    The University of Auckland Library

    Poster presented at ICSB2007 The purpose of CellML is to store and exchange computer-based mathematical models of as wide a range of scale and subject as posssible. For example, biochemical signalling and metabolic systems can be embedded in electrophysiological models of excitable cells in CellML. The CellML language is an open standard based on the XML markup language and is being developed by the Bioengineering Institute at the University of Auckland and affiliated research groups [1]. The majority of computational biology publications aim to discuss their model but often fail to provide a comprehensive set of instructions for recreating the model, or include errors preventing reproduction of published model outputs. Publishing a paper with a link to a CellML model facilitates the wide distribution and recreation of that model, and additionally forces the modeller to carefully consider matters such as unit consistency. The CellML specification and application programming interfaces (API) are driven by a core team, but a growing international community is involved in work related to CellML. A community website (www.cellml.org) has been set up as a focal point for the community and also functions as a model repository. A number of groups are developing software tools for CellML and using the language for research in computational biology. A repository of almost 300 unique CellML models is available at www.cellml.org/models: these are computational models from peer-reviewed publications that have been coded into CellML. These models are undergoing an active curation process based on the MIRIAM standard, proposed by the international biological modelling community [2]. This process includes provision of comprehensive documentation, annotation with citation and model author metadata, maintenance of file modification histories, and correspondence with model authors to ensure that models define all required initial conditions and parameters. The CellML community strongly supports collaboration with other groups to continue to set standards for curation and distribution of biological models. A number of free / open source software tools for developing and simulating CellML models are available, including Physiome CellML Environment (PCEnv) and Cellular Open Resource (COR). Other modelling environments such as JSim and Virtual Cell also support the CellML format. Information on further tools such as validators, debuggers and simulation specific packages can be found at www.cellml.org/tools. In the near future, models in the cellml.org model repository will be completely annotated with ontologies such as BioPaX and references to databases such as UniProt. Models will be broken down into the components from which they are comprised, and these components will themselves be curated, providing a toolbox of standardised computational parts from which new models can be created, in an in silico analogy to the MIT Registry of Standard Biological parts (http://parts.mit.edu/registry/index.php/Main_Page). An API has recently been developed for software tools to allow interaction between CellML and SVG diagrams of models, such as biochemical pathway schematics, and work is also underway to standardise graphical representations of CellML models.

  • Doped Diamond-Like Carbon (DLC) coated surfaces to reduce fouling from milk

    Patel, Jaiminkumar; Bansal, B; Jones, MI; Hyland, M (2010-11-09)

    Conference poster
    The University of Auckland Library

    In the dairy industry, fouling of processing surfaces is a common and unresolved problem. Surface modification, for example through the application of a surface coating, can alter the surface properties of a material, and may be a potential way to reduce fouling. Typical dairy plant stainless steel surfaces were modified by the deposition of doped Diamond-Like Carbon (DLC) films with varying concentration of doped elements. These modified surfaces were studied for their fouling behavior with milk at both laboratory and pilot scale. None of the doped DLC modified surfaces investigated in the study presented benefits in fouling reduction as compared to unmodified surface.

  • Retrospective host specificity testing of Cotesia urabae to assess the risk posed to the New Zealand nolid moth Celama parvitis

    Avila Olesen, Gonzalo; Withers, TM; Holwell, GI (2014-08-11)

    Conference poster
    The University of Auckland Library

    Additional retrospective testing of the gum leaf skeletoniser (Uraba lugens) biological control agent Cotesia urabae was conducted against the endemic moth Celama parvitis. Although this native was included in host specificity testing before EPA approved the parasitoid's release, this work aimed to increase the sample size to better assess the potential risk posed. The effect that different periods of host deprivation and prior oviposition experience had on the parasitoid's readiness to attack, was examined in a sequence of no-choice tests. No parasitoids emerged from the 52% of larvae that survived to pupation, thus, confirming C. parvitis as a non-host. Dissections of larvae that died during laboratory rearing revealed that 63% had contained a parasitoid, but no C. urabae parasitoid larvae developed beyond the second instar. Significant differences were found in the attack times according to the parasitoid's deprivation levels (age), and it was also observed that the duration until first attack significantly decreased after each non-target presentation.

    Conference poster
    The University of Auckland Library

    Poster presented at Waiheke 2008 Multiscale Modelling of the Heart Workshop. The CellML repository now contains a number of well curated CellML models of cardiac biology and physiology at the cellular and subcellular level. Recently this resource has been growing rapidly in both quality and quantity and includes models of cardiac electrophysiology, excitation-contraction coupling, myofilament mechanics, signalling systems and combinations thereof. Herein we describe the CellML model repository, its range of models, the tools used to develop and test these models and the processes and aims of curating them. The relevance of this resource to multi-scale modelling of the heart in the present and the future is then discussed.

  • Benefits of speech & language therapy for hearing impaired children

    Fairgray, Liz; Purdy, Suzanne (2008)

    Conference poster
    The University of Auckland Library

    Conference details: Reflecting Connections 2008, the second conference jointly hosted by the New Zealand Speech-Language Therapists Association and Speech Pathology Australia. Held at the SKYCITY Convention Centre in Auckland, New Zealand, from the 25th to the 29th of May, 2008. http://www.reflectingconnections.co.nz/ Although the need for speech and language therapy is widely recognized for children who are hearing impaired, there is little research evidence for improved outcomes after specific speech and language therapy interventions. With improvements in hearing aid and cochlear implant technology, and consequently improved access to the speech signal, there has been greater emphasis on listening-based therapies. The most widely used therapy is referred to as “auditory-verbal therapy” (AVT). This approach is endorsed by the Alexander Graham Bell Association, but there is paucity of research evidence for AVT effectiveness (Rhoades, 1982; Goldberg & Flexer, 1993; Wray et al., 1997; Rhoades & Chisholm, 2000). Previous studies have focused on psychosocial and educational outcomes of AVT, rather than measuring specific speech and language outcomes. The current study investigates speech and language, speech perception in noise and reading abilities before and after a 6-month period of weekly AVT with an experienced Certified Auditory-Verbal and Speech-language Therapist. Participants are eight children aged 5 to 17 years with moderate-profound sensorineural hearing loss using cochlear implants (CI) and/or hearing aids.
