    There is strong evidence that the productivity per capita of cities and regions increases with population. One likely factor behind this phenomenon is agglomeration; densely populated regions are able to bring together otherwise unlikely combinations of individuals and organisations with diverse, specialised capabilities. But clearly not all possible combinations of capability are equally valuable, nor are they equally likely. In order to investigate patterns in the typical combinations of capabilities, we have used the REGPAT patent database to construct a bipartite network of geographic regions and the patent classes for which those regions display a revealed comparative advantage. By identifying the pairs of patent classes that are most likely to co-occur within regions, we can infer relationships between the classes, giving a new network that maps out the structure of technical innovation. The resulting network has a core-periphery structure with a central group of highly connected technologies surrounded by branches of more specialised combinations. We investigate measures such as the diversity of regional patent portfolios and the ubiquity of patent classes across regions. We find that diversity is positively correlated with regional population, while the average ubiquity of patents in a region’s patent portfolio is negatively correlated. This suggests that more populous regions are able to expand into more specialised and higher value parts of the patent network.

  • Bacterially mediated manganese deposition in novel "anelli" within the biofilms of an impacted urban stream

    Smith, JP; Lewis, Gillian (2007-12-02)

    Conference poster
    The University of Auckland Library

    The purpose of this work is to identify bacteria responsible for the formation of manganese containing anelli within stream biofilms, and study their distribution. Manganese oxidising bacteria are part of a diverse group of organisms found commonly within many disparate environments, which deposit manganese and iron biominerals within biofilms and flocs [1]. The purpose of microbial manganese oxidation is poorly understood, but may be associated with energy production, mobilisation of nutrients, protection and/or detoxification [1, 2]. Manganese has a high sorptive capacity for heavy metals, metalloids, and other ions, as well as a strong oxidizing potential, and therefore frequently induces co-precipitation of cations present within the surrounding environment [1]. Within urban streams contaminants such as heavy metals may therefore potentially be concentrated within steam biofilms in the presence of manganese oxidising bacteria.

    Geoscience data capture is expensive. In order to extract maximum value, the data need to be consistently described, easily found, and then shared among those who need it. There has been recent momentum in the geoscience community to develop a common descriptive framework which facilitates data sharing. While storage and transfer standards are vital, they lack a descriptive element which standarizes the meaning of their contents. Metadata capture is appropriate for data stores, but often the terminology carries different meanings as domains become more specialised. For example, the term “migration” to a petroleum geochemist refers to the movement of hydrocarbons in geologic time, yet to a seismologist describes an imaging process. Furthermore, concepts associated with a term may change through time or as contextual factors in a discussion are modified. How, therefore, can the concepts evoked from geoscience resource terminology be defined and aligned to represent this multi-scaled orthogonal variability? Here we show how a community knowledge acquisition exercise was orchestrated to discuss fundamental concepts and their meanings as interpreted by leaders in basin characterization. The result of this exercise is a formal description of many of the features and processes associated with sedimentary basins, i.e. a basin ontology. This ontology allows the use of semantic connections between concepts as a backbone for search and discovery of research artifacts in large data stores.

  • At your service: An interactive, flexible web-service for translating classification systems and taxonomies

    Whitehead, Brandon; Banchuen, Tawan; Gahegan, Mark; Smart, William; Masoud-Ansari, S (2010-11-11)

    Geoscientists have developed and applied classification systems and taxonomies in an effort to enhance and share their understanding of complex geoscience information. However, the classification systems and taxonomies used throughout the geosciences for land cover and land use, soils, geology are neither static nor universal; the classes that we use to represent the Earth vary considerably with time and from place to place. As a general example, think of a geologic map. There are instances when mapped data contains desirable categories, but the granularity of those categories is not suitable. There are also instances where two or more maps (or data sets) lack the desired categories, or the categories across maps are semantically incompatible. This is to be expected, given that: (i) new science, social and economic agendas change what we may wish to differentiate when we look at a map and (ii) new technologies make differentiation of previously inseperable classes more reliable, thus viable. This paper describes ongoing work to create a web-based semantic translation service that allows users to: (i) experiment with mappings between classification systems and taxonomies; (ii) visualize translation maps using a given mapping; and (iii) persist their translation maps, and share them with others. Semantic equivalence and similarity are supported via underlying ontologies, which also facilitate the merging and re-grouping of classes.

  • The CellML Model Repository as a Resource for Cardiac Modelling

    Lawson, J.R.; Nobile, P.J.; Lloyd, C.M.; Neilsen, P.F.; Hunter, P.J. (2008)

    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.

  • Over-expression of Human Amylin Leads to Oligomerization and beta-cell Dysfunction Associated with Mitochondrial Uncoupling, Activation of c-Jun and Decrease Expression of JNK Interacting Protein-1

    Over-expression of human amylin (hA) in pancreatic β-cells has been shown to contribute to cytotoxic hA aggregation and islet amyloid formation that can lead to β-cell dysfunction in type-2 diabetes mellitus. We aimed to investigate the functional and molecular changes associated with hA oligomer formation and their relation to β-cell dysfunction and diabetes development using transgenic mouse model that over-expresses hA in their islet β-cells.We showed that both homozygous and hemizygous hA transgenic mice developed spontaneous diabetes with different elevated levels of hA and with different time frame of disease onset and death. Homozygous mice displayed hyperinsulinemia and self-limiting insulin resistance during the pre-diabetic state, whereas by contrast, hemizygous mice had a longer prediabetic phase without insulin resistance. Intracellular and extracellular oligomers were clearly detectable before onset of diabetes with strong correlation with the time of β-cell apoptosis occurred in homozygous but not in hemizygous mice, indicating a difference in the extent of cytotoxic oligomerization between these animals. In addition, RT-qPCR analysis demonstrated progressive decrease in β-cell expression of functional and key regulatory molecules such as insulin, amylin, Pdx1, MafA, Glut2 and GCK. We also detected changes in expression of the mitochondrial membrane protein UCP-2 which contributes to decreased mitochondrial function. Further molecular analysis demonstrated activation of c-Jun/JNK and decrease expression of JNK-interacting protein 1, suggesting their role in mediating beta-cell death/apoptosis. Our studies should lead to a better understanding of the role and regulation of hA-evoked β-cell dysfunction and β-cell death in diabetes
