  • The Maori cultural institution of hui : when meeting means more than a meeting.

    O'Sullivan, John; Mills, Colleen (2009)

    University of Canterbury Library

    Within all societies individuals gather together for various reasons and in a variety of ways for events that can be collectively termed “meetings”. The Māori cultural institution termed hui is often translated into English as a meeting (Cormack, 2000, Ryan, 2001). Using Volkema and Niederman’s (1996) input/ context-process-output model of the meeting, hui, as described by expert Māori informants, is compared with how Western corporate meetings are depicted in management and communication textbooks used in New Zealand universities over the last decade. The analysis shows that, while the Western approach to meetings and hui share common features, equating the two forms of communication event is inappropriate and results in the key cultural dimensions of hui being ignored. The authors propose that a more thorough explanation of the forms, functions, and cultural underpinnings of both hui and Western style meetings is required in our tertiary textbooks to ensure our students are adequately prepared for their future roles, which in Aotearoa New Zealand will entail working across Western and Māori group communication settings in an appreciative and informed manner.

  • Bullying the boss : upwards bullying as a response to destructive supervisory leadership in the workplace.

    Wallace, Belinda (2009)

    Masters thesis
    University of Canterbury Library

    Despite a growing acknowledgement of the negative outcomes for organizational functioning and the health and well-being of individuals attributable to workplace bullying, research into the phenomenon of upward bullying (supervisors bullied by their subordinates), particularly its aetiology, has received modest attention. The aim of the present study was to explore the link between destructive supervisory leadership and upward bullying and the mediating or moderating roles of perceived interactional justice, continuance commitment and workrelated meaning in this relationship. Two hundred and eight post-graduate students and two hundred and four work-based subordinate employees completed an on-line survey of their perceptions of the leadership style and interactional justice of their immediate supervisor, the levels of their own continuance commitment and work-related meaning, and the frequency with which they engaged in specific bullying behaviours targeting their supervisor. As expected, subordinate perceptions of destructive supervisory leadership were strongly associated with an increased incidence of upward bullying, with the strength of this relationship partially mediated by subordinate perceptions of interactional justice within supervisory interactions. In addition, subordinate levels of continuance commitment and work-related meaning moderated the relationship between subordinate perceptions of interactional justice and the incidence of upward bullying, such that this relationship was intensified when either, or both the level of subordinate continuance commitment or work-related meaning was higher. This paper offers preliminary support for conceptualizing upwards bullying as a retaliatory response to destructive leadership, however due to a reliance on cross-sectional data, inferences of causality cannot be made. Practical implications and directions for future research are discussed.

  • European Union Interregionalism and the Capability-Expectations Gap

    Doidge, M. (2009)

    Journal Articles
    University of Canterbury Library

    This article addresses interregionalism in EU external relations. It considers the nature of interregionalism centred on two functional varieties - an internally focused, capacity building interregionalism and an externally focused, globally active form - and, in broad brush strokes, the evidence for each of these forms in EU interregional strategies. On this basis, it notes a capability-expectations gap in the EU's approach to interregionalism, with a certain dissonance between the Union's apparent acknowledgement of limited regional actorness in its partner groupings on the one hand and, on the other, its coincident high-level expectations as to what is achievable in the context of these relationships. The article concludes by suggesting priority areas for EU interregional strategy.

  • User-centred mobile navigation system interface development for improved personal geo-identification and navigation

    University of Canterbury Library

    Introduction Orientating and navigating with the use of mobile navigation systems involves interaction with different sources of information. Landmarks are very important into linking these sources. However, outcomes of user research projects in such fields are not yet fully implemented in the mobile navigation systems that are currently available. Objectives The objectives of this paper are the presentation and explanation of a conceptual model of the interactions between the users of a geo-mobile application, their mental maps, reality and the mobile map displays. This model is used to create a series of guidelines for a usable mobile (carto-) graphic interface which contributes to the implementation of a prototype design solution. Methodology In order to meet the objectives of the research, two main sources of information are used: already existing research literature and the results of the analysis of two of our experiments with real users. The aim of the first experiment was to compare different methodologies for field-based usability testing of geo-mobile applications. Investigating the behaviour of pedestrian visitors to unfamiliar cities while orientating and navigating with the use of already existing geo-mobile applications was the aim of the latter. Results A conceptual design of a user interaction model as well as user interface prototype design solutions for personal geo-identification and navigation can be considered as the concrete outcomes of the research described in this paper. The results also demonstrate the importance of landmarks in the geo-identification and navigation processes of the users. Conclusions Following User-Centred Design in order to develop a more usable mobile cartographic interface for pedestrian navigation can reveal a lot of information regarding the user-environment-system interactions. Several design aspects can be extracted from modeling these interactions that could be used for the prototype development. However, usability testing is needed to determine the success of the followed approach.

  • Influenza della composizione granulometrica sul comportamento tenso-deformativo dei terreni sabbiosi

    Gazzellone, A.; Albano, M.; Chiaro, G.; Modoni, G. (2009)

    Conference Contributions - Published
    University of Canterbury Library

    La ricerca intrapresa, di carattere sperimentale e teorico ha l'obiettivo di analizzare l'influenza della composizione granulometrica sulle caratteristiche fisiche e sulla risposta meccanica di terreni sabbiosi sottoposti a condizioni di carico variabile. A questo scopo si riportano i primi risultati di una vasta campagna di indagini sperimentale su campoini di terreno sabbioso ricostituiti in laboratorio con diverse composizioni granulometriche. In particolare si sono considerati Quattro assortimenti monogranulari, ciascuno caratterizzato da una diversa dimensione dei grani, sei assortimenti bi-granulare ed uno tri-granulare, ottenuti componendo con diverse percentuali i materiali monogranulari. Per tutti questi terreni si sono determinati, attraverso procedure sperimentali standard (ASTM D4252 e D4253), i valori minimi e massimi della densita e si e valutata l'efficacia di diverse modalita di compattamento. Successivamente sono state analizzate le permeabilita dei diversi materiali variando il loro livello di addensamento. L'ultima fase, tuttora in corso, riguarda l'esecuzione di prove triassiali eseguite applicando percorsi di carico monotonici e ciclici con una cella a percorso di carico controllato munita di idonea strumentazione per la misura locale degli spostamenti. I risultati di queste prove costituiscono la base sperimentale per la valutazione, attraverso l'impiego di modelli teorici opportunamente scelti, dell'influenza della composizione granulometrica dei terreni sulla loro risposta meccanica a diversi livelli di deformazione.

  • Education, Death and Awakening: Hesse, Freire and the Process of Transformation

    Roberts, P. (2009)

    Journal Articles
    University of Canterbury Library

    Education is a key theme in a number of Hermann Hesse's novels and short stories. This paper focuses on Hesse's last and longest fictional work, The Glass Bead Game, and analyses the transformation of Joseph Knecht, the central character, in the light of Paulo Freire's theory of education. It is argued that over time Knecht develops a critical consciousness, becoming less certain of his certainties, more aware of his own incompleteness, and increasingly convinced of the importance of teaching. Dialogue plays a pivotal role in the development of Knecht's critical awakening and his understanding of himself and his vocation as a human being. The paper discusses the relationship between conscientisation and contemplation, considers the significance of death as a theme in the novel, and reflects on some of the educational implications arising from Hesse's work.

  • Average observational quantities in the timescape cosmology

    Wiltshire, D.L. (2009)

    Journal Articles
    University of Canterbury Library

    We examine the properties of a recently proposed observationally viable alternative to homogeneous cosmology with smooth dark energy, the timescape cosmology. In the timescape model cosmic acceleration is realized as an apparent effect related to the calibration of clocks and rods of observers in bound systems relative to volume–average observers in an inhomogeneous geometry in ordinary general relativity. The model is based on an exact solution to a Buchert average of the Einstein equations with backreaction. The present paper examines a number of observational tests which will enable the timescape model to be distinguished from homogeneous cosmologies with a cosmological constant or other smooth dark energy, in current and future generations of dark energy experiments. Predictions are presented for: comoving distance measures; H(z); the equivalent of the dark energy equation of state, w(z); the Om(z) measure of Sahni, Shafieloo and Starobinsky; the Alcock–Paczy´nski test; the baryon acoustic oscillation measure, DV ; the inhomogeneity test of Clarkson, Bassett and Lu; and the time drift of cosmological redshifts. Where possible, the predictions are compared to recent independent studies of similar measures in homogeneous cosmologies with dark energy. Three separate tests with indications of results in possible tension with the CDM model are found to be consistent with the expectations of the timescape cosmology.

  • Gravitational energy as dark energy: Towards concordance cosmology without Lambda

    Wiltshire, D.L. (2009)

    Conference Contributions - Published
    University of Canterbury Library

    I briefly outline a new physical interpretation to the average cosmological parameters for an inhomogeneous universe with backreaction. The variance in local geometry and gravitational energy between ideal isotropic observers in bound structures and isotropic observers at the volume average location in voids plays a crucial role. Fits of a model universe to observational data suggest the possibility of a new concordance cosmology, in which dark energy is revealed as a mis-identification of gravitational energy gradients that become important when voids grow at late epochs.

  • Analysis of forecasted travel time benefits against those realised

    Keshaboina, Akhylesh (2009)

    Masters thesis
    University of Canterbury Library

    There is lack of knowledge on how well the transport projects work once implemented. This research project seeks to investigate how the forecasted benefits claimed during the economic appraisal of the projects compare with the actual benefits realised. This study carried out a literature review on how the travel time benefits are forecasted for transport investment projects and comments on general to specific issues like value of travel time, international and local experiences of forecasting travel time savings to use of traffic modelling in forecasting travel time savings. The study also carried out a post-construction evaluation of projects on a diverse range of transport projects from realignments, grade separated interchange to the installation of HOV lanes and urban bypass project. Post-construction analysis was carried out and then compared against those assumed for the pre-construction evaluation and possible reasons for the differences were discussed.

  • Exposing 3-separations in 3-connected matroids.

    Oxley, James; Semple, Charles; Whittle, Geoff (2009)

    Discussion / Working Papers
    University of Canterbury Library

    Let ? be a 3-connected matroid other than a wheel or a whirl. In the next paper in this series, we prove that there is an element whose deletion from ? or ?∗ is 3-connected and whose only 3- separations are equivalent to those induced by ?. The strategy used to prove this theorem involves showing that we can remove some element from a leaf of the tree of 3-separations of ?. The main result of this paper is designed to allow us to do this.

  • On approximation of optimizing phylogenetic diversity for cluster systems

    Faller, Beáta; Semple, Charles; Steel, M. A. (2009)

    Discussion / Working Papers
    University of Canterbury Library

    A basic question in conservation biology is how to maximize future biodiversity as species face extinction. One way to approach this question is by measuring the diversity of a set of species in terms of the evolutionary history that those species span in a phylogenetic tree. Maximizing the resulting 'phylogenetic diversity' (PD) is one prominent selection criteria for deciding which species to conserve. The basic PD optimization problem aims to find a k-element subset of a given species set that has maximum PD among all such subsets. In this paper, we consider a generalization of this problem, which arises in situations where we do not know the true tree, or where evolution is not tree-like. We show that a greedy algorithm gives a (1-e⁻¹)-approximation to the general PD optimization problem, and that there is no polynomial-time algorithm that achieves a better approximation ratio unless P=NP.

  • Hope in Troubled Times? PESA and the Future of Philosophy of Education

    Roberts, P. (2009)

    Journal Articles
    University of Canterbury Library

    Contributors to this special issue have been asked to provide self-portraits of their intellectual lives and to consider the development of the Philosophy of Education Society of Australasia (PESA) as an organisation. My approach in addressing this task will be to keep the autobiographical details to a minimum and to focus more on the prospects for philosophy of education within contemporary institutions of higher education. Attention will be paid to the New Zealand context and the role PESA has played, and can continue to play, in keeping philosophy of education alive. I shall argue that while the challenges to retaining robust programmes of philosophy of education in university contexts are substantial, there is considerable hope for the future of our field in the work of newer and younger scholars.

  • An Investigation of Excessive Rural Network Harmonic Levels Caused by Particular Irrigation Pumps

    Hardie, S.; Watson, N.; Gosbell, V. (2009)

    Conference Contributions - Published
    University of Canterbury Library

    High and increasing voltage Total Harmonic Distortion (THD) and 5th harmonic voltage levels have been measured in recent years on Orion NZ Ltd's rural 11 kV distribution network in Canterbury, New Zealand. On occasion, at Points of Common Coupling (PCC), the THD has exceeded the 5% limit and the 5th harmonic has exceeded the 4% limit. It has been suspected that these summer season high harmonic levels are due to the large existing and increasing density of farm irrigation deep well pump loads. It is likely that adverse effects on the network and neighbouring loads would become apparent if the increasing harmonic levels are left unchecked. A practical and theoretical investigation was conducted by the Electric Power Engineering Centre (EPECentre), University of Canterbury, on behalf of Orion to determine what are the primary causes of the high harmonic levels and provide mitigation options. Several farms with installed irrigation pumps were visited and the harmonic current and voltage levels were measured when the pumps were operating. Substation measurements were also simultaneously taken. A computer harmonic model of the local 11 kV network and loads was created that provided an accurate description of actual network conditions. An examination of Orion's system from the view of harmonic management was performed. The investigation revealed that the most significant cause of high harmonics levels is the comparatively large harmonic current injections by local irrigation pumps using Variable Speed Drives. A secondary cause is resonances in the network, often dynamically created by Power Factor (PF) capacitors switching online at various farms. To keep the rural network infrastructure in an effective and sustainable operating condition, mitigation measures are needed. Options researched included simulations of harmonic filters placed at various network points, and the use of alternate vector group transformers. Suggestions are made regarding objectives for harmonic limits at different network voltage levels, so as to determine harmonic limits for load installations.

  • The properties of elliptic curves containing singularities over the field Zp

    Jamieson-Lane, Alastair David (2009)

    Doctoral thesis
    University of Canterbury Library

    The study of elliptic curves is an important part of modern cryptography. In this report we consider the properties of singular elliptic curves over the field Zp, showing that they can always be factorized, that their equations always take a given form and that there are always p + 1 ± 1 points satisfying this equation over the field Zp.
