  • Rights, Culture and Constitutions: The case for greater engagement with cultural values in the interpretation of Pacific Constitutions

    Kelly, Danielle (2010-12-13)

    This paper looks at the need for judges in Pacific courts to have a greater engagement with cultural values when interpreting constitutional rights. Almost all Pacific nations have supreme law constitutions, and almost all of these contain rights provisions of some description. The relevance of these rights provisions being enshrined in supreme law documents is that decisions and actions of the executive government, the legislature and other decision-making (and often democratically elected) bodies can be challenged and overturned on the basis of being inconsistent with those rights. The mandate for constitutional rights to be used in this way is far more clear than for rights that are not constitutionally recognised, and the inclusion of these rights in domestic supreme law documents gives them a relevance to the local law not necessarily shared by non-constitutionally recognised rights.

  • An analytical model for the break-even credit default swap spread with o counterparty default risk in Hall(2009): A pedagogical approach.

    Choi, Daniel F.S. (2010)

    University of Waikato

    Professor Hull in his textbook [Hull, J. C. Options, Futures, & Other Derivatives, Edition 7, Pearson, 2009] illustrates the determination of the credit default swap (CDS) spread by a numerical example. This paper follows the assumptions used by Professor Hull and provides a reduced form formula for the CDS spread. The CDS spread can be simplified by the Taylor series into a function of two variables, the default probability and the recovery rate. Rearranging this simplified formula, the default probability, expressed as the ratio of the CDS spread and the loss given default, is equivalent to the average default intensity, or, the hazard rate defined in Hull [2009, p.500].

  • An interactive environment for explanatory biological modeling

    Langley, Patrick (2010)

    Conference item
    The University of Auckland Library

    In this paper, we describe an interactive environment for the representation, interpretation, and revision of explanatory biological models. We illustrate our approach on the systems biology of aging, a complex topic that involves many interacting components. We also report initial experiences with using this environment to codify an informal model of aging. We close by discussing related efforts and directions for future research.

  • A command language for taskable virtual agents

    Langley, Patrick; Trivedi, N; Banister, M (2010)

    Conference item
    The University of Auckland Library

    In this paper, we report progress on making synthetic characters more taskable. In particular, we present an English-like command language that lets one specify complex behaviors an agent should carry out in a virtual environment. We also report compilers that translate English commands into a formal notation and formal statements into procedures for ICARUS, an agent architecture that supports reactive execution. To demonstrate the benefits of such taskability, we have integrated ICARUS with TWIG, which provides a simulated physical environment with humanoid agents. We use the command language to specify three complex activities, including responding to an object contingently, collecting and storing a set of objects, and negotiating with another agent in order to purchase an item. We also discuss related work on controlling synthetic characters, along with paths for additional research on taskability.

  • Learning from errors by counterfactual reasoning in a unified cognitive architecture

    Danielescu, A; Stracuzzi, DJ; Li, N; Langley, Patrick (2010)

    Conference item
    The University of Auckland Library

    A key characteristic of human cognition is the ability to learn from undesirable outcomes. This paper presents a computational account of learning from errors based on counterfactual reasoning, which we embed in ICARUS, a unified theory of the cognitive architecture. Our approach acquires new skills from single experiences that improve upon and mask those that initially produced the undesirable behavior. We demonstrate the operation of this model in a simulated urban driving environment. We also relate our approach to other research on error-driven learning and discuss possible improvements to the framework.

  • Integrated systems for inducing spatio-temporal process models

    Park, C; Bridewell, W; Langley, Patrick (2010)

    Conference item
    The University of Auckland Library

    Quantitative modeling plays a key role in the natural sciences, and systems that address the task of inductive process modeling can assist researchers in explaining their data. In the past, such systems have been limited to data sets that recorded change over time, but many interesting problems involve both spatial and temporal dynamics. To meet this challenge, we introduce SCISM, an integrated intelligent system which solves the task of inducing process models that account for spatial and temporal variation. We also integrate SCISM with a constraint learning method to reduce computation during induction. Applications to ecological modelling demonstrate that each system fares well on the task, but that the enhanced system does so much faster than the baseline version.

  • Mother-of-snow-white (msw) a maternal effect allele affecting behavior and the formation of the left- right axis in zebrafish (Danio rerio)

    The vertebrate body plan displays distinct left-right asymmetries in the position of visceral organs. This asymmetrical organization extends to the vertebrate brain that is both anatomically and functionally asymmetric. The development of left-right patterning and cerebral lateralization are thought to be regulated by evolutionary conserved genes. Here we report the evidence of the maternal effect allele mother-of-snow-white (msw) controlling the establishment of LR body asymmetries in a vertebrate embryo suggesting conserved mechanisms in the evolution and establishment of this trait. In a recent study Facchin and colleagues [1] showed that the progeny of lines of zebrafish artificially selected for the right eye preference in scrutiny a mirror had a significant increase in the frequency of reversed left-right asymmetry in the epithalamus. In the present study it is proposed that Facchin???s selection for behavioral lateralization could have lead to the isolation of a spontaneous maternal effect allele responsible for the disruption of normal left-right patterning in zebrafish neuroanatomical structures. We analyzed the genetic transmission of the msw allele and we identified three different classes of females according to the percentage of reversed brain asymmetries in their offspring. Females generating a frequency of 0-5% (class I), between 5 and 12.5% (class II) and females generating more than 12.5% (class III) of progeny with reversed asymmetries. Animals from the last group were considered as homozygous recessive females for the msw allele (HRF). We also investigated in the three classes the expression of members of signaling pathways responsible for the establishment of visceral and diencephalic left-right asymmetries and measured the size of Kupffer???s vescicle (KV). We found that HRF offspring had smaller KV and, sometimes, no vesicle at all. We could observe a correlation between the frequency of reversed parapineal and the size of KV. The msw allele has shown to be semi-dominant as class II females showed an intermediate phenotype. Our hypothesis suggests that smaller size of KV can reduce the amount of morphogens accumulated by the leftward flow, thus leading to a randomization of the expression of genes of the Nodal pathway. Moreover we evidenced significant behavioral differences between fish with opposite parapineal position subjected to various laterality tests. We could also discuss a complex but relevant influence of neuroanatomical asymmetries on zebrafish personality [2]. Now using Paired-end Mapping and next-generation sequencing techniques (SOLiD approach) we are aiming at identifying the msw allele. 1. Facchin, L., F. Argenton, and A.

  • Designing a Mixed Reality Framework for Enriching Interactions in Robot Simulations

    Chen, IY; MacDonald, Bruce; Wuensche, Burkhard (2010)

    Conference item

    Experimentation of expensive robot systems typically requires complex simulation models and expensive hardware setups for constructing close-to-real world environments in order to obtain reliable results and draw insights to the actual operation. However, the test-development cycle is often time-consuming and resource demanding. A cost-effective solution is to conduct experiments by replacing expensive or dangerous components with simulated counterparts. Based on the concept of Mixed Reality (MR), robot simulation systems can be created to involve real and virtual entities in the simulation loop. However, seamless interaction between objects from the real and the virtual world remains a challenge. This paper presents a generic framework for constructing MR environments that facilitate interactions between objects from different dimensions of reality. In comparison to previous frameworks, we propose a new interaction scheme that describes the necessary stages for creating interactions between real and virtual objects. We demonstrate the strength of our MR framework and the proposed MR interaction scheme in the context of robot simulation. 1

    Systematic differences between left ventricular (LV) volumes measured by cardiac magnetic resonance (CMR) and 2D echocardiography have been reported: 2D echo significantly underestimates LV volumes. Mitral regurgitation (MR) due to mitral valve prolapse (MVP) is associated with LV volume overload and remodelling, including increased chamber sphericity. We compared LV volumes in 25 patients (pts) with MVP and at least moderate MR by CMR and echo on 2 different days, 2-4 weeks apart.

  • Sketch-Based Robot Programming

    Barber, C; Shucksmith, R; MacDonald, Bruce; Wuensche, Burkhard (2010)

    Robots are rapidly becoming a part of everyday life and have now moved from industrial environments to household, medical and entertainment applications. In order to make full use of robots new interfaces need to be developed, which allow inexperienced human users to instruct (program) robots, without having to understand programming and the underlying electronics and mechanics. In this paper we present a novel sketch-based interface for robot programming. We have identified applications which are difficult to represent algorithmically, but can be easily represented with sketch input. We then define a range of sketch impressions allowing the user to define a wide range of behaviours within these application domains. Our system uses a Pioneer robot with an arm and a fixed overhead camera. The user sketches into the camera view and the sketch input is interpreted, mapped into the 3D domain, and translated into robot interactions. Current applications include specification of robot paths and obstacles, covering regions (e.g., patrolling in security applications or seed sowing in agricultural applications), and directing the robot arm, e.g., to pick up objects. A user evaluation of the system demonstrates that the interface is intuitive and, with the exceptions of controlling the arm, all interactions are perceived as easy to perform.

  • Antioxidants for female subfertility the results of a Cochrane systematic review

    Clarke, Jane; Showell, Marian; Hart, RJ (2010-06)

    Conference item
    The University of Auckland Library

    Assisted reproductive therapies (ART) do not cure subfertility they simply seek to potentially overcome its barriers. It is proposed that supplementary measures including the modification of environmental and biochemical factors, for example taking dietary supplements such as oral antioxidants may improve fertility treatment outcomes (Ebisch, 2007).
