    Assistive Technology (AT) for care of older people is now a major focus area for research, given the ageing of population and diminishing number of available caregivers. Robots have recently been recognized as a potential platform for remote monitoring and delivering healthcare assistance to older people. A literature search was conducted to explore potential issues and lessons learnt in similar situations. Surprisingly, the acceptance of home care technology by older people has not been a serious problem after proper introduction and training; however important practical challenges were related to privacy, autonomy and ethical responsibility. It was observed that an ethical framework for AT is virtually non-existent and is needed for people who feel vulnerable in dependent situations. A further challenge that potentially impedes AT implementation is its acceptance by the existing care giving workforce because of a perceived threat from technology to take away their jobs, add to their responsibilities and make them vulnerable to consequences borne out of a recorded human error. Aged Care Facility managers, caregivers and medical professionals have concerns, including: practical workflow adjustment, equipment maintenance, accuracy, cost effectiveness and potential for errors. International regulatory framework is generally supportive though variations exist across political boundaries. Using robot based AT solutions for elder care is desirable, and represents a promising technology option, but we must consider several non-technical implications before designing solutions.

  • Issues of Authenticity and Chronology in the Sacred Works of Leopold Hofmann

    Badley, Allan (2010)

    Conference item
    The University of Auckland Library

    Around 650 manuscript copies of sacred works with attributions to the eighteenth-century Viennese composer Leopold Hofmann have survived into the 21st Century.i Few of these copies are in score and none, bar a brief Alleluja setting is indisputably in the composer???s hand. Most of Hofmann???s sacred works are preserved in manuscript parts of varying degrees of reliability and, all too often, of uncertain provenance. ...

  • Moving on from single words: The use of dynamic video stimuli for verb therapy

    McCann, Clare; Greig, LE (2010)

    Conference item
    The University of Auckland Library

    This single case study is based on Webster & Whitworth (2007) but with a novel adaptation of dynamic video stimuli rather than static picture material. We demonstrate the effectiveness of this type of verb and sentence therapy in JL (29 years) who had a left MCA infarct resulting in severe nonffuent aphasia and apraxia of speech almost five years previously. Verbal expression was restricted to one-two word utterances. Comprehension of active canonical sentences was accurate but he had difficulty understanding passive sentences and object clauses. On assessment all errors were on reversible sentences suggesting a selective verb retrieval impairment (Berndt et al, 1997).

  • Overheating steel in an annealing furnace

    Taylor, Stephen; Wang, Shixiao (2010)

    Conference item
    The University of Auckland Library

    We consider a strip of steel passing through a very long furnace which is heated by electric elements. Annealing of steel involves heating the steel to change its microstucture and such furnaces are used to accomplish this. The problem is to model the temperature within the furnace in order to control the annealing of the steel. A model developed at MISG 2004 for the furnace fails to predict a physical distortion of the steel that can occur near its edges. We look at various modifications of the model in order to explain this.

  • Effectiveness of Visualisations for Detection of Errors in Segmentation of Blood Vessels.

    Schooten, Boris W van; Dijk, Elisabeth MAG van; Suinesiaputra, Avan; Reiber, Johan HC (2010)

    Vascular disease diagnosis often requires a precise segmentation of the vessel lumen. When 3D (Magnetic Resonance Angiography, MRA, or Computed Tomography Angiography, CTA) imaging is available, this can be done automatically, but occasional errors are inevitable. So, the segmentation has to be checked by clinicians. This requires appropriate visualisation techniques. A number of visualisation techniques exist, but there has been little in the way of user studies that compare the different alternatives. In this study we examine how users interact with several basic visualisations, when performing a visual search task, checking vascular segmentation correctness of segmented MRA data. These visualisations are: direct volume rendering (DVR), isosurface rendering, and curved planar reformatting (CPR). Additionally, we examine if visual highlighting of potential errors can help the user ???nd errors, so a fourth visualisation we examine is DVR with visual highlighting. Our main ???ndings are that CPR performs fastest but has higher error rate, and there are no signi???cant differences between the other three visualisations. We did ???nd that visual highlighting actually has slower performance in early trials, suggesting that users learned to ignore them.

  • A large-scale empirical study of practitioners??? use of object-oriented concepts

    Gorschek, Tony; Tempero, Ewan; Angelis, Lefteris (2010-05)

    Conference item
    The University of Auckland Library

    We present the first results from a survey carried out over the second quarter of 2009 examining how theories in objectoriented design are understood and used by software developers. We collected 3785 responses from software developers world-wide, which we believe is the largest survey of its kind. We targeted the use of encapsulation, class size as measured by number of methods, and depth of a class in the inheritance hierarchy. We found that, while overall practitioners followed advice on encapsulation, there was some variation of adherence to it. For class size and depth there was substantially less agreement with expert advice. In addition, inconsistencies were found within the use and perception of object-oriented concepts within the investigated group of developers. The results of this survey has deep reaching consequences for both practitioners and researchers as they highlight and confirm central issues.

  • Stereoscopic Particle Image Velocimetry Measurement of Articulatory Airflow for Validation of a Computer Model of Speech

    Spence, CJT; Geoghegan, PH; Lu, XB; Jermy, MC; Hunter, Peter; Cater, John (2010)

    The interaction of the airflow and the vocal articulators while speaking is not completely understood. The regions of articulation in the airway are flow obstructions that convert aerodynamic energy into acoustic energy and can be passive (stationary) such as the teeth and hard palette, or active (moving) in the case of the lower lip and tongue. By modifying the positions of the vocal articulators and the various sounds that make up speech can be generated. Models of the articulators have been constructed from Magnetic Resonance Imaging (MRI) scans taken during quiet breathing, and articulatory kinematics were obtained from Electromagnetic Articulography (EMA) and a video of the face. A three-dimensional computer model that can represent the motion of vocal articulators and simulate the airflow during vowels and consonants has also been developed. A fricative is a hissing or buzzing consonant that is produced when a steady air stream is forced through a constriction in the oral cavity and the flow state becomes transitional or even turbulent. In the current paper Stereoscopic Particle Image Velocimetry (SPIV) measurements of the airflow through the modelled vocal tract geometries for the production of "s" and "sh" fricatives are presented.

  • Contrasting Teacher's Espoused and Enacted Classroom Assessment: Exploring Hong Kong Chinese Teachers??? Conceptions of Assessment

    Hui, SKF; Brown, Gavin (2010)

    Conference item
    The University of Auckland Library

    A new survey instrument on Teachers Conceptions of Assessment in Chinese contexts has been developed and validated with confirmatory factor analysis of responses from Hong Kong and South China primary and secondary school teachers. The factor model identifies four main conceptions (i.e., ???irrelevant???, ???accountability???, ???improvement???, and ???examination???) with the latter three being multifaceted. This paper reports an exploratory study designed to explain the purposes and uses for a self-selected sample of classroom assessment tasks of four primary school curriculum leaders in Hong Kong Chinese medium schools. A combination of methods ??? qualitative interviewing and self-scoring of their confidence to the use of these assessment tasks in achieving different conceptions ??? was used. Results indicated although ???improvement??? was often quoted as the reason to why the selected assessment tasks facilitate students??? learning, their thought of having the tasks to meet the functions of ???accountability??? and ???examination??? is still unyielding. The work reported here will contribute to gaining an understanding of the relationship between assessment policy and practice in the Chinese context and how Hong Kong???s ???assessment for learning??? policy is conveyed to the classrooms in such a context.

    Modularity is crucial for the in silico design and testing of biological systems [1]. Recently, we developed an online library of modular mathematical model components for synthetic biology [2] using the modular model exchange format CellML [3]. In addition to synthetic biology, where new biological constructs are being created, this library is now being extended for general intracellular modeling in the biomedical context [4,5] as researchers seek to understand the wealth of systems already existing in the natural world.

  • Diboron porphyrins and corroles: unexpected chemistry for both boron and the ligands

    Brothers, Penelope; Albrett, AM; Mlodzianowska, A; Boyd, Peter; Clark, George; Gonzalez, E; Ghosh, A (2010)

    Conference item
    The University of Auckland Library

    Over recent years we have investigated the chemistry of boron porphyrins, which are unique in containing two boron atoms per porphyrin ligand. Highlights have been the development of a series of complexes, a diboryl porphyrin, a diboranyl porphyrin containing a B-B bond which forms through spontaneous reductive coupling of the diboryl under certain conditions, and a further diboranyl complex which is an unusual example of an isophlorin in which the porphyrin ligand has been reduced. A number of complexes containing oxygen-bridged BOB units have also been prepared. Our most recent work extends the coordination chemistry of boron to the corrole ligand. Although corroles and porphyrins are closely related, we observe some significant differences in the boron chemistry. The more constrained hole size of corrole leads to cisoid stereochemistry in the FBOBF corrole anion (Figure), compared to transoid for the related FBOBF porphyrin. We have also isolated boron hydride corrole complexes, including an unusual example of a complex containing a B-H-B group coordinated to the cavity in the corrole. The experimental work for the boron porphyrin and corrole work has been supported by extensive DFT calculations. Recent experimental results will be described, along with potential applications of the boron porphyrin complexes.

  • The boundaryless career: A productive concept that may have outlived its usefulness.

    Inkson, James; Ganesh, S; Roper, J; Gunz, H (2010)

    Conference item
    The University of Auckland Library

    Boundaryless career theories and discourse are increasingly prominent in career studies and management studies, and are considered part of a new ???status quo. This paper contextualises career studies and the boundaryless careers literature in terms of its actual and potential contribution to career studies, acknowledging the contributions already made to broadening and deepening knowledge. It draws on a corpus of 60 recent boundaryless career papers to offer a critique based on six issues: the accuracy of the term ???boundaryless career??? as a label; the loose definitions of boundaryless career; the impact and disciplinary location of boundaryless career theory; the over-emphasis on personal agency in boundaryless career theory; the normalization of boundaryless careers; and the lack of empirical support for the emergence and prominence of boundaryless careers. Arising from our critique, we propose new directions for career studies.

  • A Computer Program to Calculate the Stream Exergy using the Visual Basic Graphical Interface

    Munir, Muhammad; Chen JJ; Young BR (2010-09-29)

    Conference item
    The University of Auckland Library

    The thermodynamic concept of exergy unequivocally indicates what is wasted in terms of energy. Exergy is the component of energy which is available for useful work. This concept can be used to appraise the eco-efficiency of a process. A process is highly eco-efficient if products of that process have exergy values close to those of its raw materials. All systems including chemical, biological and material processes feed on energy and convert some part of it into useful work and the remaining portion is disposed to the environment as entropy. This paper presents a new calculation method for the exergy of multi-component two phase process streams which allows the calculation of exergy gains of material streams for the calculation of the Relative Exergy Array (REA) (Montelongo-Luna et al., 2010). The total exergy calculation method developed in this work differs from most other authors by dividing total exergy into its constitutive components of chemical exergy, physical exergy and the exergy change due to mixing. The exergy calculation method developed has been incorporated within a commercial process simulator as an additional property of a material stream along with other orthodox calculations like mass and energy balances. Some external data in the form of standard chemical exergies is required. Exergy loss is determined by comparing exergy in and exergy out from a process after exergy analysis. An example calculation of the total exergy of a material stream is presented. The resulting calculated exergy values can then be used as a tool for energy efficient process design, energy efficient process control and optimization.

  • Mutations of Cypovirus Polyhedrin and Applications of Polyhedra to Protein Nanocontainers

    Ohtsuka, Y; Nakai, D; Coulibaly, F; Cooper, Yui; Metcalf, Peter; Mori, H (2010)

    Cypoviruses, a member of the family Reoviridae, are one group of insect virus that produce micrometer-sized protein crystals called cytoplasmic polyhedra. Many virus particles are occluded in polyhedra to protect them against extracellular environment. Recently we have developed a novel method for protein immobilization into polyhedra. It is possible to use these polyhedra to device ultra-stable protein nanocontainers. However, a weak point of the protein nanocontainers is that polyhedra dissolve only in very high pH condition (pH > 10). It seems important now to carry out structure-based engineering of polyhedrin to derive mutants for multiple purposes, for example, such that the crystals can be dissolved at pH values that are not as drastic. We have identified a cluster of tyrosine at a packing contact, deprotonation of which is likely to cause disruption of the lattice at very alkaline pH. It is perhaps possible to test the effect of substitution of these tyrosine residues by other amino acids. We show that the substitutions of some residues in a cluster of tyrosine lead to modify a solubility of polyhedra. The results suggest that the modified polyhedra can serve as the basis for the development of robust and versatile nanoparticles for biotechnological applications.
