  • Daniel Spoerri's Carnival of Animals

    Novero, Cecilia (2012)

    Book item
    University of Otago

    This innovative, accessible, and thorough collection addresses an admirable range of historical and geographical contexts to demonstrate that the human relationship with other species is complex and overdetermined, and that human systems of knowledge and representation are crucial for negotiating this uneven terrain. An essential teaching text, Gorgeous Beasts will find a welcome home in the HAS classrooms of many disciplines.” —Sherryl Vint, author of Bodies of Tomorrow: Technology, Subjectivity, Science Fiction “With a multidisciplinary approach combining historical studies and the study of visual representations, with a period focus centered on the late eighteenth and nineteenth centuries but also reaching back to the Renaissance and forward to contemporary works, and with contributions from some of the most prominent and thought-provoking scholars in the field of animal studies, Gorgeous Beasts energetically advances the current conversation about the human uses of nonhuman animals. Several essays investigate and seek to remedy the lack of representation involved in past and present silences concerning the slaughter of animals, while others investigate the problematic representations of animals as creatures of the wild, objects of scientific study, trophies, or biomass to be harvested. The attention paid to the contemporary artists Daniel Spoerri and Mark Dion makes explicit the links between the historical analyses and our current situation. Raising provocative and important questions, this volume sets the terms for future studies of the representation of other animals by humans.” —Frank Palmeri, University of Miami “This book introduces us to gorgeous beasts—creatures we yearn for, treasure, misunderstand, and mistreat. Enclosure-endangered Atlantic codfish, bloodhounds unleashed on the Maroon uprisings in Jamaica, taxidermied elephants that conferred secondhand majesty on trophy hunters, slither-painting snakes, even dog-skin gloves and civet-scented perfumes (those animal-made objects): all testify to our human co-construction of, with, and by animals. In the book’s lush illustrations, the visual representation of animals has equal footing with their material and economic histories, and the result is a thought-provoking and sense-igniting treat.” —Susan Merrill Squier, author of Poultry Science, Chicken Culture: A Partial Alphabet and Liminal Lives: Imagining the Human at the Frontiers of Biomedicine “Gorgeous Beasts is a gorgeous book. As the essays revel in the physicality of animal bodies in order to reveal why and how animals matter in history and art, so the volume celebrates the physical book. Extensively illustrated, expertly designed, and printed on sumptuous paper, it embodies the best of the exhibition catalogue and the scholarly text. Like a finely curated art exhibit, it speaks to the myriad and contradictory ways that animals matter through individual works that are a pleasure to behold, read, and contemplate.” —Amy Nelson, American Historical Review “Edited by Joan B. Landes, Paula Young Lee, and Paul Youngquist, Gorgeous Beasts brings together nine essays by some of the most sophisticated voices within animal studies to explore the histories and desires shaping human encounters with other animals, both alive and dead. . . . Gorgeous Beasts asks all the right questions. Its animal bodies are provocative, unpredictable, and potent. Meticulously researched and eloquently argued with clear, accessible language, the essays incite a knowing that grows beyond the page and into our daily lives with other animals.” —Rachel Poliquin, Humanimalia “The essays in this book explore the important, sometimes ambiguous roles that animals play in human culture.” —E. K. Mix, Choice

  • Environmental input-output analysis of the New Zealand dairy industry

    Flemmer, CL (2012-01-02)

    Journal article
    Massey University

    This work presents data and analysis quantifying the total (direct and indirect) resource use and outputs (products and pollutants) of the New Zealand dairy industry for the year April 1997 to March 1998. It also identifies those sectors supplying the dairy industry which make significant indirect contributions to its total inputs and outputs. Although this data is 14 years old, it is the only large-scale, detailed data available. Further, more modern data can be compared with this baseline data. Comparison with the other major New Zealand food and fibre sectors shows that the dairy farming sector has the highest total water consumption and the highest total effluent. It also has high total land use, electricity use and production of animal methane. The dairy processing sector is water and fuel intensive and has high total water effluent and greenhouse gas emissions. The high resource use and pollutants have to be weighed against the enormous economic value of the dairy sectors.

  • Methods for identifying plant materials in Māori and Pacific textiles

    Lowe, Bronwyn J; Smith, Catherine A (2012)

    Conference paper
    University of Otago

    Investigating the range of plant species used in Māori and Pacific textiles can help to understand the diversity and relationships among whatu and raranga techniques and art forms. Although the style and construction of Māori and Pacific textile artefacts often give clues as to the plant species used, positive species identification is not always possible from visual inspection. This may be due to the age and condition of the artefact, or effects of leaf processing such as splitting, softening, stripping or dying. A range of laboratory methods and published resources are however available to help with the identification process. Understanding the internal and surface anatomy of raw leaf material (e.g. Carr and Cruthers 2007; Carr et. al. 2009), the effects of leaf preparation for weaving on leaf anatomy (e.g. King 2003) and the expected condition of specimens sampled from artefacts can aid the interpretation of data collected in the laboratory. The most appropriate method of specimen preparation is another important consideration. This paper provides a review of microscopy and tomography techniques and online resources, which have been trialled and implemented in the Clothing and Textile Sciences Department at the University of Otago for the identification of plant species of interest in New Zealand and the Pacific. The advantages and disadvantages of these techniques and resources for identifying plant materials in artefacts will be discussed.

    OBJECTIVE: The Hurst exponent (HE) is a nonlinear method measuring the smoothness of a fractal time series. In this study we applied the HE index, extracted from electroencephalographic (EEG) recordings, as a measure of anesthetic drug effects on brain activity. METHODS: In 19 adult patients undergoing sevoflurane general anesthesia, we calculated the HE of the raw EEG; comparing the maximal overlap discrete wavelet transform (MODWT) with the traditional rescaled range (R/S) analysis techniques, and with a commercial index of depth of anesthesia - the response entropy (RE). We analyzed each wavelet-decomposed sub-band as well as the combined low frequency bands (HEOLFBs). The methods were compared in regard to pharmacokinetic/pharmacodynamic (PK/PD) modeling, and prediction probability. RESULTS: All the low frequency band HE indices decreased when anesthesia deepened. However the HEOLFB was the best index because: it was less sensitive to artifacts, most closely tracked the exact point of loss of consciousness, showed a better prediction probability in separating the awake and unconscious states, and tracked sevoflurane concentration better - as estimated by the PK/PD models. CONCLUSIONS: The HE is a useful measure for estimating the depth of anesthesia. It was noted that HEOLFB showed the best performance for tracking drug effect. SIGNIFICANCE: The HEOLFB could be used as an index for accurately estimating the effect of anesthesia on brain activity.

  • Gap junctions modulate seizures in a mean-field model of general anesthesia for the cortex

    Steyn-Ross, ML; Steyn-Ross, DA; Sleigh, James (2012-06)

    Journal article
    The University of Auckland Library

    During slow-wave sleep, general anesthesia, and generalized seizures, there is an absence of consciousness. These states are characterized by low-frequency large-amplitude traveling waves in scalp electroencephalogram. Therefore the oscillatory state might be an indication of failure to form coherent neuronal assemblies necessary for consciousness. A generalized seizure event is a pathological brain state that is the clearest manifestation of waves of synchronized neuronal activity. Since gap junctions provide a direct electrical connection between adjoining neurons, thus enhancing synchronous behavior, reducing gap-junction conductance should suppress seizures; however there is no clear experimental evidence for this. Here we report theoretical predictions for a physiologically-based cortical model that describes the general anesthetic phase transition from consciousness to coma, and includes both chemical synaptic and direct electrotonic synapses. The model dynamics exhibits both Hopf (temporal) and Turing (spatial) instabilities; the Hopf instability corresponds to the slow (≲8 Hz) oscillatory states similar to those seen in slow-wave sleep, general anesthesia, and seizures. We argue that a delicately balanced interplay between Hopf and Turing modes provides a canonical mechanism for the default non-cognitive rest state of the brain. We show that the Turing mode, set by gap-junction diffusion, is generally protective against entering oscillatory modes; and that weakening the Turing mode by reducing gap conduction can release an uncontrolled Hopf oscillation and hence an increased propensity for seizure and simultaneously an increased sensitivity to GABAergic anesthesia.

  • A theoretical and experimental investigation of roof flexibility on internal and net roof pressure dynamics in low-rise buildings with a dominant opening’

    Guha, TK; Sharma, Rajnish; Richards, Peter (2012)

    Journal article
    The University of Auckland Library

    A theoretical and experimental study of the effect of roof flexibility on the dynamics of internal and net roof pressure is reported in thsi paper. A two-degree-of-freedom dynamic model and its simplified counterpart, the single-degree-of-freedom quasi-static model is sued for theoretical analysis. As an illustrative example, admittance and spectra of internal and net roof pressure is presented for a medium-sized industrial building with different roof flexibilities using these models. Complementary wind tunnel investigations using a felixible Styrofoam roof are carried out to validate the model predictions. Additionally, effect of the dominant opening size and wind direction (i.e. angle of attack) on internal pressure for the flexible roof is experimentally investigated in the wind tunnel with a comparison to those for a rigid roof model.

  • Translating Love

    Dureau, Christine (2012-06)

    Journal article
    The University of Auckland Library

    This article addresses relationships between personal experience and cross-cultural understanding of maternal love. I analyze claims of mutual maternal understanding by women on Simbo, Western Solomon Islands, highlighting the contexts in which they expressed love in compassionate terms and the interplay of fieldwork intersubjectivity. Although assumptions of a priori emotional comprehension grounded in apparently similar experiences are problematic, it is possible to develop degrees of mutual emotional knowledge through the exchanges of participant-observation. The concept of “emotional communities” serves as a fruitful way of conceptualizing both the diverse contexts in which people express aspects of taru (love) and the emotional engagement of cross-cultural fieldwork.

  • Anti-consumption and society: Proceedings of ICAR 2012 Brisbane

    Lee, Michael; Cherrier, H; Rundle-Thiele, S (2012)

    Book
    The University of Auckland Library

    Griffith Business School is committed to research that develops and promotes social, financial and environmental approaches that lead to sustainable businesses and communities. In Volume 2, Issue 3 of the Journal of Social Marketing, Gerard Hastings asks “When a supermarket chain attains such dominance that it covers every corner of a country the size of the UK, threatens farmers’ livelihoods with its procurement practices, undercuts local shops and bullies planners into submission, it becomes reasonable to ask: does every little bit really help? Once the 100 billionth burger has been flipped and yet another trouser button popped it is sensible to wonder: are we still lovin’ it? As the planet heats up in response to our ever increasing and utterly unsustainable levels of consumption, it is fair to question: are we really worth it?” (Hastings, 2012). Ongoing attention needs to be directed by the research community to understand the impact that our consumption behaviour has on ourselves, our loved ones, our society, and our planet. Research attention that challenges society to question its own practices is central in assisting us to understand how we can build sustainable communities. The International Centre for Anti-consumption Research (ICAR) 2012 symposium encourages us to question whether our aim to live independently is ideal. A child’s desire to leave home may promote economic growth, but does little to keep loved ones and communities closely connected. Sustainable business practice models are needed if we are to step away from the economic growth model that underpins business today. Sharing rather than consuming may be one mechanism that business can use to reengineer business practice. Research presented at ICAR 2012 suggests that to achieve sustainable business and communities we need to understand the opposition and resistance, including boycotts that have emerged against business. This understanding is rapidly evolving in an Internet- dominated era where social media landscapes are mushrooming. To develop a more social approach that leads to sustainable business and consumption, researchers must understand that anti-consumption is not an exact opposite of consumption. A range of behaviours and their underlying motives remain under-researched, and avenues to broaden our focus are showcased at ICAR 2012. Sustainability requires that individuals and communities engage in a diverse range of behaviours including decreasing resource use (water, energy, and materials). A practical stance is introduced at ICAR 2012 with empirical evidence highlighting how community-based social marketing is being used throughout the world to foster sustainable behaviour change.

  • Recommendations for rescue of a submerged unresponsive compressed-gas diver.

    Mitchell, SJ; Bennett, MH; Bird, N; Doolette, DJ; Hobbs, GW; Kay, E; Moon, RE; Neuman, TS; Vann, RD; Walker, R; Wyatt, HA (2012-11)

    Journal article
    The University of Auckland Library

    The Diving Committee of the Undersea and Hyperbaric Medical Society has reviewed available evidence in relation to the medical aspects of rescuing a submerged unresponsive compressed-gas diver. The rescue process has been subdivided into three phases, and relevant questions have been addressed as follows. Phase 1, preparation for ascent: If the regulator is out of the mouth, should it be replaced? If the diver is in the tonic or clonic phase of a seizure, should the ascent be delayed until the clonic phase has subsided? Are there any special considerations for rescuing rebreather divers? Phase 2, retrieval to the surface: What is a "safe" ascent rate? If the rescuer has a decompression obligation, should they take the victim to the surface? If the regulator is in the mouth and the victim is breathing, does this change the ascent procedures? If the regulator is in the mouth, the victim is breathing, and the victim has a decompression obligation, does this change the ascent procedures? Is it necessary to hold the victim's head in a particular position? Is it necessary to press on the victim's chest to ensure exhalation? Are there any special considerations for rescuing rebreather divers? Phase 3, procedure at the surface: Is it possible to make an assessment of breathing in the water? Can effective rescue breaths be delivered in the water? What is the likelihood of persistent circulation after respiratory arrest? Does the recent advocacy for "compression-only resuscitation" suggest that rescue breaths should not be administered to a non-breathing diver? What rules should guide the relative priority of in-water rescue breaths over accessing surface support where definitive CPR can be started? A "best practice" decision tree for submerged diver rescue has been proposed.

  • Dispersion of windborne debris

    Richards, Peter (2012-05)

    Journal article
    The University of Auckland Library

    The dispersion of windborne debris that is caused by the object's aerodynamics and shape is investigated. It is shown that the flight may be divided into two phases. The initial phase, where the relative velocity is high and the rate of rotation low, is characterised by high transverse accelerations. The second phase, which has much lower accelerations, can be modelled as that of a compact object, where only the drag force is significant. The initial conditions for the second phase are determined by the initial phase. Approximate solutions to the equations of motion are proposed for rectangular plate and rod type debris. The results are is good agreement with wind tunnel observations.

  • Pressures on a cubic building-Part 2: Quasi-steady and other processes

    Richards, Peter; Hoxey, RP (2012-03)

    Journal article
    The University of Auckland Library

    This paper explores the relationship between the turbulent flow within the atmospheric boundary layer and the surface pressure on a building, the Silsoe 6. m cube, immersed deep within that boundary layer. In the past, the main approach has been to examine the statistical properties of both surface pressure and boundary layer flow independently as correlations are poor. However, accepting that the statistical properties of the flow at a point within the boundary layer at a given height are invariant with location, it is then shown that the quasi-steady analytical technique can account for much of the measured surface pressure fluctuations. The simplified quasi-steady-vector model, which relates surface pressure to variations in dynamic pressure and wind direction, is shown to give close comparison with measured values for the standard deviation, the maximum and the minimum surface pressure. The remaining differences are discussed and explained. © 2011 Elsevier Ltd.
