    No full text
    This text deals with the role of chance in a theoretical manner, presents some images produced computationally from a set of algorithms that rely on chance. It also introduces, briefly, the production of the art group [+zero] (www.maiszero.org), composed of four Brazilian artists and researchers who create computer art from indeterminate situations based on the philosophical concept of play

    Digital image manipulation: an interdisciplinary approach.

    No full text
    Image manipulation programs allow users to retouch drawings or photographs. Using these tools for artistic image manipulation is a demanding task. In this paper we present a novel methodology, based on efficient image processing algorithms in combination with Cellular Automata, to create a very versatile and autonomous means for altering digital images. The system presents a newly achieved level of autonomous creativity in addition to minimising the effort for retouching images from an artistic point of view. We present an evaluation of an experimental implementation of our method and provide suggestions for its applicability

    Working in and Against Hybrid Landscapes: Reflections on the Skills and Capabilities of Chief Officers in UK Local Government

    No full text
    This chapter examines the educational and developmental demands of public managers, exploring the necessary skills and competences required to move across the hybrid landscapes within which they increasingly work. Drawing on in-depth interviews with chief officers in local authorities across the United Kingdom, it first argues that the work of chief officers leads them to navigate between and across different dimensions: be it between sedimented and emergent institutions; “leaping in” and “leaping ahead” performances of leadership; and bonded or bridging relations. Assessing the requisite skills and behaviors of officers to move across such dimensions, the chapter draws attention to the capabilities of serial adaptation, authenticity, and puzzling. Such capabilities are not easily codified, being generated through experiential learning, and nurtured through the demands of reflexive practice. Spaces for reflexive practice are, it is claimed, integral to the developmental demands, resilience, and well-being of public managers, thereby privileging novel forms of critical reflection, action learning, and leadership development that facilitate the opening up of spaces of learning that straddle both theory and everyday practices. Ultimately, however, such forms of learning do not always sit well with the performance management mechanisms of teaching and learning, as well as learners’ own expectations of the classroom. They arguably destabilize traditional power relations between the lecturer and the student, advancing the conditions for the further democratization of the classroom. The study thus ends with a call for more destabilization and experimentation in the provision of novel spaces of learning for public managers and public managers of the future

    Stakeholder Views of the Factors Affecting the Commercialization of Aviation Biofuels in Europe

    No full text
    Biofuels are being advocated by certain sections of the commercial aviation industry as a means of reducing greenhouse gas emissions and lowering fossil-fuel dependency within the confines of current aircraft technology and infrastructure. Rising oil prices, increasingly stringent environmental legislation, and continued growth in air travel demand have stimulated the development of renewable lower-carbon fuel alternatives that can act as a substitute for conventional Jet A1 kerosene. However, although biofuels may offer a number of apparent benefits, barriers to widespread commercial uptake and deployment remain, including concerns about competition for feedstocks and impact on global water resources and biodiversity. The processes involved in the uptake of aviation-grade biofuels are not straightforward and there is a need to explore the factors affecting commercial deployment. This paper reports on the findings of a series of in-depth semistructured interviews with key aviation stakeholders in Europe. The research reveals that concerns about the supply of suitable feedstocks, uncertainty surrounding the true life-cycle emissions savings of the fuels, and the perceived lack of policy support are key obstacles that need to be addressed before aviation biofuels can be widely utilized. The research also reveals that the potential inclusion of aviation within the EU Emissions Trading Scheme will create a zero accounting “loophole” for biofuel that may uniquely influence the pattern of uptake in the EU vis-à-vis other world markets. Additional key constraints identified include limitations on the supply of suitable feedstocks, concerns about sustainability of the fuels, and uncertain policy support
