    This thesis explores the management practices of a small number of women in management positions within a large government department in New Zealand, and the factors influencing those practices. Using a feminist standpoint epistemology the study took as its starting point the day to day experiences of managers and their staff. Through analysis of these experiences the context of New Public Management and the reforms of the public sector in New Zealand that took place in the 1980's and 1990's were identified as important features in the management practices of the participants. The study found that the doctrines of New Public Management were embedded within the organisation from which participants were drawn. Within this context, they had an organising or mediating effect on the day to day management practices of the participants, what they valued, how they perceived management and the language they used to talk of their experiences. Overall the participants did not consider that gender relations created either supports or constraints to their management practices or their entry into management positions. They considered that gender-related constraints were a thing of the past. They did, however, note particular events that suggested that women managers continue to be judged in relation to deeply held gender stereotypes. The management practices that the participants valued and/or described as their own practice did not conform to the gendered dichotomies of management that have been prevalent in the literature on successful management and women in management in particular. The participants demonstrated a more androgynous approach to management that is adaptive and sensitive to the wider context

    Battery cell thermal-conductive coating increases efficiency

    Get PDF
    Thin coating of high-temperature epoxy resin provides necessary electrical insulation, as well as good thermal conductivity between battery cells. Insulation increases efficiency of nickel-cadmium battery, as it would any multicell battery assembly in which cell-to-cell thermal balance is critical

    A Decade of Urban History: The Historical Urban Studies Series

    Get PDF
    The first half of the 1990s was a pivotal period in the development and growth of urban history in Europe. In Britain the Urban History Group began to convene again after a decade in abeyance, work commenced on the three-volume Cambridge Urban History of Britain, the Urban History Yearbook became Urban History whilst the European Association of Urban Historians organized their first conference. It was in this climate that Ashgate Publishing commissioned a new monograph series, Historical Urban Studies, under the editorship of Richard Rodger, editor of Urban History, and Jean-Luc Pinol, the leading French urban historian and a key figure in the European Association of Urban Historians (EAUH). The aim of the series was and is to be comparative over both time and space, drawing on multiple locations to explore what is common and what distinctive about the urban experience of diverse towns and nations. The broad agenda for the series was shaped by an overarching concern with the administration and governance of the city which underpinned attempts to manage the social, economic and political challenges wrought by 300 years of urban change. In particular, the editors stress the importance of the comparative element which should allow historians to distinguish ‘which were systematic factors and which were of a purely local nature’. The editors set themselves an ambitious agenda and this essay aims to explore how the series has developed over the ten or so years since it commenced publication; the degree to which it has provided a platform for advancing the sub-discipline of urban history; and to consider some future directions which urban history might take

    Adhesive for cryogenic temperature applications

    Get PDF
    Adhesive, which bonds a metal liner to a filament wound composite structure used for cryogenic pressure vessels, prevents the metal liner from buckling under depressurization. The adhesive consists of adducts of urethane and epoxy resins

    Virtual regeneration

    Regenerating our increasingly polluted, worn-out urban infrastructure is becoming the singly most important challenge facing our cities. Simon Doyle and Michael Batty explain how spatial information technologies and online laboratories can enable many diverse interests to participate in creating informed planning policies that best address these issues

    Slow, Continuous Beams of Large Gas Phase Molecules

    Cold, continuous, high flux beams of benzonitrile, fluorobenzine, and anisole have been created. Buffer-gas cooling with a cryogenic gas provides the cooling and slow forward beam velocities. The beam of benzonitrile was measured to have a forward velocity peaked at 67 ±5\pm 5 m s1^{-1}, and a continuous flux of 101510^{15} molecules s1^{-1}. These beams provide a continuous source for high resolution spectroscopy, and provide an attractive starting point for further spatial manipulation of such molecules, including eventual trapping

    Actinometry of Hydrogen Plasmas

    Get PDF
    Optical emission spectroscopy (OES) can be used to map the electron energy distribution of hydrogen plasmas. Using actinometry, a type of OES where trace amounts of noble gases are introduced, the effect of discharge power on the electron temperature of hydrogen plasmas was explored. This was done using argon and krypton as actinometers for low pressure hydrogen plasmas. It was determined that the electron temperature decreased with respect to power supplied to the discharge

    Highly Optimized Tolerance: Robustness and Design in Complex Systems

    Get PDF
    Highly optimized tolerance (HOT) is a mechanism that relates evolving structure to power laws in interconnected systems. HOT systems arise where design and evolution create complex systems sharing common features, including (1) high efficiency, performance, and robustness to designed-for uncertainties, (2) hypersensitivity to design flaws and unanticipated perturbations, (3) nongeneric, specialized, structured configurations, and (4) power laws. We study the impact of incorporating increasing levels of design and find that even small amounts of design lead to HOT states in percolation

    Highly Optimized Tolerance: Robustness and Power Laws in Complex Systems

    Get PDF
    We introduce highly optimized tolerance (HOT), a mechanism that connects evolving structure and power laws in interconnected systems. HOT systems arise, e.g., in biology and engineering, where design and evolution create complex systems sharing common features, including (1) high efficiency, performance, and robustness to designed-for uncertainties, (2) hypersensitivity to design flaws and unanticipated perturbations, (3) nongeneric, specialized, structured configurations, and (4) power laws. We introduce HOT states in the context of percolation, and contrast properties of the high density HOT states with random configurations near the critical point. While both cases exhibit power laws, only HOT states display properties (1-3) associated with design and evolution.Comment: 4 pages, 2 figure

    Power Laws, Highly Optimized Tolerance, and Generalized Source Coding

    Get PDF
    We introduce a family of robust design problems for complex systems in uncertain environments which are based on tradeoffs between resource allocations and losses. Optimized solutions yield the “robust, yet fragile” features of highly optimized tolerance and exhibit power law tails in the distributions of events for all but the special case of Shannon coding for data compression. In addition to data compression, we construct specific solutions for world wide web traffic and forest fires, and obtain excellent agreement with measured data
