    Griffiths, Kerry; Lindesay, J (2006-10-03)

    Report
    The University of Auckland Library

    In 2002 the Parliamentary Commissioner for the Environment (PCE) signaled in his "Creating Our Future" report, the emergence of "Triple Bottom Line" (environmental, social and economic) reporting in New Zealand: "Other options include the business sector adopting models such as Triple Bottom Line (TBL) reporting and the Natural Step that raise awareness about sustainable ways of doing business." (p17) Since that time TBL reporting has continued to develop in New Zealand in both the public and private sector albeit in a variety of forms and under a variety of names - including Sustainable Development Reporting, Corporate Responsibility Reporting, Sustainability Reporting. This paper provides an update on TBL Reporting in New Zealand since 2002 and covers: - the international context - the state of reporting in New Zealand - the value of reporting - concluding comments While the paper provides a brief commentary on TBL reporting by public sector agencies, the focus of the paper is on reporting by the business sector (including CRIs and state owned enterprises). This paper does not attempt to provide a critical and thorough analysis on the extent to which corporate sustainability reporting contributes to sustainable development per se, although some comment is made on that subject.

  • Evaluation of the Tokelau Draft Science Curriculum (External review)

    Salter, David (2006)

    Report
    The University of Auckland Library

    School science throughout the world during the 1960s and 70s was concerned primarily with preparing students for careers in science. However as a large majority of students had no aspiration to be scientists, the emphasis of school science changed during the 1980s towards a science education that would provide students with the knowledge and skills that would enable them to live productive and fulfilling lives in a world that was becoming more technologically advanced. During the 1990’s the notion of ‘Science for all’ developed as the goal of school science, whereby all students would gain a level of science literacy that could allow them to engage in informed debate about socio-scientific issues and to solve problems in a critical and logical manner. ...

  • On Cournot Equilibria in Electricity Transmission Networks.

    Downward, A; Zakeri, Golbon; Philpott, Andy (2006)

    Report
    The University of Auckland Library

    We consider electricity pool markets in radial electricity transmission networks in which the lines have no transmission losses, but have transmission capacities. At each node there is a strategic generator submitting generation quantities to the pool. Prices are determined by a linear competitive fringe at each node. We derive necessary and sufficient conditions on the line capacities that ensure that the unconstrained one-shot Cournot equilibrium remains an equilibrium in the constrained network. These conditions are characterized by a convex polyhedral set.

  • Interactive Decision Support in Radiation Therapy Treatment Planning

    Ehrgott, Matthias; Winz, Ines (2006)

    Report
    The University of Auckland Library

    This paper proposes the use of an interactive decision support system to guide the treatment planning process for external beam radiation therapy. Based on multicriteria optimisation our research treatment planning software Carina calculates efficient (also called Pareto optimal) treatment plans. These are stored in a database and accessed for evaluation by the treatment planner. The interactive component consists of navigation among the precalculated plans using free search, fine search and exact search as well as sensitivity analysis, which extracts dose dependence information for all structures from the plan database. As a result, plan quality is improved by finding advantageous trade-offs in competing treatment plans, trial-and-error is avoided, and effectiveness of treatment planning is increased.

  • Identifying the Principal Axes of a Birefringent Material by Polarisation Classification

    Unsworth, Charles; Lesurf, J (2006)

    Report
    The University of Auckland Library

    A novel use of a 'Rotary Polariser Quasi-Optical System' to locate the principal axes of a birifringent material is presented. It will be demonstrated that by examination of the ellipticity of the beam, one can determine the orientation of such principle axes and hence optimize the performance of Faraday Rotators.

  • Observation of frequency dependent Faraday angle resonance in ferrites & new ellipticity characterisation of freespace Faraday rotators at mm-wavelength

    Unsworth, Charles; Lesurf, James (2006)

    Report
    The University of Auckland Library

    This article, reports ‘Frequency Dependent Faraday Angle Resonance’ in a magnetic sample at millimetric frequencies for the first time using a fully automated rotary polariser quasi-optical system. This serves to compliment the original work performed by Raum at Terahertz frequencies in the Frequency independent region of a magnetic material. In addition, it is shown how the same instrument can be used further classify the performance of a Freespace Faraday Rotators, by the introduction of a new ‘ellipticity’ parameter measurement. This serves to identify what physical mechanism is responsible for the isolation that occurs across the device’s operating region, hence, providing a further insight into the operation of the device.

  • An Automated Oscillator Tuning System for Gunn Oscillator Characterisation at MM-Wavelengths

    Unsworth, Charles; Lesurf, James (2006)

    Report
    The University of Auckland Library

    This article presents an ‘Automated Oscillator Tuning System’ (AOTS) that together with mechanical motorized fixtures can be used to automatically adjust the frequency and backshort tuners of a coaxial cavity, resonant cap mm-wave oscillator via a computer program. Here we demonstrate how the AOTS can be used to quickly and accurately characterise a coaxial cavity, resonant cap mm-wave oscillator with frequency increments of 100MHz. The oscillator characterisation took 10 minutes with the AOTS as compared to 1hr+ minutes if performed manually and with larger frequency increments. By writing an appropriate computer control program, the AOTS can be adapted to many types of application. Thus, the AOTS has the potential to be versatile with wide functionality.

  • Generalising the Kuramoto Model for the study of Neuronal Synchronisation in the Brain

    Unsworth, C; Cumin, D (2006)

    Report
    The University of Auckland Library

    In this article, we have generalised the Kuromoto model to allow one to model neuronal synchronisation more appropriately. The generalised version allows for different connective arrangements, time-varying natural frequencies and time-varying coupling strengths to be realised within the framework of the original Kuromoto model. By incorporating the above mentioned features into the original Kuromoto model one can allow for the adaptive nature of neurons in the brain to be accommodated. Extensive tests using the Generalised Kuromoto model were performed on a N=4 coupled oscillator network. Examination of how different connective arrangements, time-varying natural frequencies and time-varying coupling strengths affected synchronisation separately and in combination are reported. The effects on synchronisation for large N are also reported.

  • High Dimensional Function Approximation ( Regression, Hypersurface Fitting ) by an Active Set Least Squares Learning Algorithm

    Kecman, Vojislav (2006)

    Report
    The University of Auckland Library

    This is a report on solving regression (hypersurface fitting, function approximation) prob-lems in high dimensional spaces by novel learning rule called Active Set - Least Squares (AS-LS) algorithm for kernel machines (a.k.a. support vector machines (SVMs)) and RBF (a.k.a. regularization) networks, multilayer perceptron NNs and other related networks. Regression is a classic statistical problem of learning from empirical data (i.e., examples, samples, measurements, records, patterns or observations) where the presence of a training data set D = {[x(i), y(i)]   n  , i = 1,...,N} is a starting point in reaching the solution. (N stands for the number of the training data pairs and it is therefore equal to the size of a set D). Often, yi is denoted as di (ti), where d (t) stands for a desired (target) value. The data set D is the only information available about the dependency of y upon x. Hence, we are dealing with the supervised learning problem and solution technique here. The basic aim of this report is to give, as far as possible, a condensed (but systematic) presentation of a novel regression learning algorithm for training various data modeling networks. The AS-LS learning rule resulted from an extension of the active set training al-gorithm for SVMs as presented in (Vogt and Kecman, 2004, 2005). Unlike for SVMs where one uses only the selected support vectors (SVs) while computing their dual vari-ables i, in an AS-LS method all the data will be used while calculating the weights wi of the regressors (i.e., SVs) chosen at a given iteration step. Our focus will be on the con-structive learning algorithm for regression problems (although the same approach applies to the classification (pattern recognition) tasks ). In AS-LS we don't solve a quadratic pro-gramming (QP) problem typical for SVMs. Instead, the overdetermined least squares prob-lem will be solved at each step of an iterative learning algorithm. As in active set method for SVMs, a single data point violating the 'Karush-Kuhn-Tucker' (KKT) conditions the most will be selected and added as the new support vector i.e., regressor at each step. However, the weights wi of the selected regressors will be computed by using all the avail-able training data points. Thus, unlike in SVMs, the non-regressors (non-SVs) do influence the weights of regressors (SVs) in an AS-LS algorithm. A QR decomposition of a systems matrix H for calculating wi will be used in an iterative updating scheme with no need to find the matrix Q at all. This makes AS-LS fast algorithm. In addition, the AS-LS algo-rithm with box-constraints -C  wi  C i = 1, NSV, has also been developed, and this resem-bles the soft regression in SVMs. The resulting model is parsimonious, meaning the one with a small number of support vectors (hidden layer neurons, regressors, basis functions). Comparisons to the results obtained by classic SVMs are also shown. A weighted AS-LS algorithm that is very close to active set method for solving QP based SVMs learning problem has been introduced too.

  • Pasifika location and privilege: conceptual frameworks from first year Pasifika social work students

    Passells, Vaolesi (2006)

    Report
    The University of Auckland Library

    Research focus/aims: To develop an understanding of the process by which Pasifika social work students draw links between social work theory and practice. Participants: Six first year social work students of Samoan, Tonga and Cook Island heritage. Key findings/outcomes: The illustrations presented show these students 'making sense' of their formal academic training by creating/exploring conceptual frameworks through which they express identity (in terms of multiple identities that include being island born and raised, island born and raised in Aotearoa, born and raised in Aotearoa, fluent or not in one's home island language. They also explore belonging in terms of mediating normative value systems (for example, in terms of ethnicity, the mainstream, relationship with Tangata Whenua). Scope: Presents a snapshot of student responses to the invitation to draw links between theory and practice in 'reflection journals' kept during the first year of social work education at the Auckland College of Education Centre for Social Work.

  • Lot sizing with inventory gains

    Waterer, Hamish (2006)

    Report
    The University of Auckland Library

    This paper introduces the single item lot sizing problem with inventory gains. This problem is a generalization of the classical single item capacitated lot sizing problem to one in which stock is not conserved. That is,the stock in inventory undergoes a transformation in each period that is independent of the period in which the item was produced. A 01 mixed integer programming formulation of the problem is given. It is observed, that by projecting the demand in each period to a distinguished period, that an instance of this problem can be polynomially transformed into an instance of the classical problem. As a result, existing results in the literature can be applied to the problem with inventory gains. The implications of this transformation for problems involving dierent production capacity limitations as well as backlogging and multilevel production are discussed. In particular, it is shown that the polynomially solvable classical constant capacity problems become NP-hard when stock is not conserved.

  • Multiobjective Programming and Multiattribute Utility functions in Portfolio Optimizations

    Ehrgott, Matthias; Waters, Chris; Gasimov, Rafail; Ustun, Ozden (2006)

    Report
    The University of Auckland Library

    In recent years portfolio optimization models that consider more criteria than the standard expected return and variance objectives of the Markowitz model have become popular. For such models, two approaches to find a suitable portfolio for an individual investor are possible. In the multiattribute utility theory (MAUT) approach a utility function is constructed based on the investor’s preferences and an optimization problem is solved to find a portfolio that maximizes the utility function. In the multiobjective programming (MOP) approach a set of efficient portfolios is computed by optimizing a scalarized objective function. The investor then chooses a portfolio from the efficient set. We outline these two approaches using the UTADIS method to construct a utility function and present numerical results for an example.

  • A fully automated quasi-optical, rotary polariser system for use at MM-wavelengths

    Unsworth, Charles; Lesurf, James (2006)

    Report
    The University of Auckland Library

    This article, describes the development of a fully automated rotary polariser quasi-optical system for use at millimetric frequencies. It is reported how the system can accurately measure the rotation and ellipticity that may be induced on a linearly polarised Gaussian Beam when it passes through a magnetic material under study with ~1% error. The system is demonstrated by the automatic characterisation of a plastoferrite sample in approximately 6 hrs using the ‘Faraday Angle Resonance’ method. This was a significant time saving over the conventional reflectance method which would take a skilled researcher ~ 1 week to perform. It is also reported how measurement of the ‘Minor Faraday Angle’ can produce more accurate results at mm-wavelengths.

  • A sensitive genetic-based detection capability for Didymosphenia geminata

    Cary, S. Craig; Hicks, Brendan J.; Crawford, Naomi; Coyne, Kathryn J. (2006-12)

    Report
    University of Waikato

    It is now well recognized that the increase in global transportation over the last two decades has brought with it an increased potential for the introduction of unwanted microorganisms (aquatic or terrestrial) that may have drastic effects on human and ecosystem health and agriculture. We have developed and validated a unique genetic fingerprinting tool for D. geminata. In concert, we developed field collection and preservation techniques specific for D. geminata along with genetic-based procedures that can now reliably detect D. geminate from a complex environmental community with a high degree of sensitivity. Recent work (Phase 2) has shown that the described methods will provide detection levels from <1 – 10,000 cells ml-1. We contend that the genetic based detection approaches used in this study offer great promise to meet the increasing demands to monitor the global threat from invasive micro-organisms.
