    Social Relevance in Lowenfeld’s Creative and Mental Growth

    Get PDF
    For the sake of this panel presentation, I am defining social relevance to mean that aspect of an art education textbook which fosters a growth relationship between the student and his or her social and physical environment. Ten Minutes is not much time to deal with this, either in depth or detail. This entire panel could be spent discussing the varieties of social growth in Lowenfeld\u27s Creative and Mental Growth. I\u27m sure each of the panelists could say the same about the books they are covering

    Developing a model to predict aircraft maintenance performance

    [Abstract]: A three-pronged approach was adopted to the investigation of causes of maintenance errors in army aviation. In the first phase of the research, analysis of maintenance incident reports suggested that individuals were mostly at fault, making errors because they failed to follow procedures and were inadequately supervised. Interviews with maintenance technicians, on the other hand, put the spotlight on organisational variables, such as pressures created by poor planning. In the third phase, a survey instrument administered to 448 maintenance workers was used to develop a structural model that predicted 34% of the variance in psychological health, 16% of the variance in turnover intentions, and 16% of the variance in self-reported maintenance errors. Implications of these findings are discussed

    Energy issues in the developing world

    In 1986 and 1987 the lower oil prices called into question many of the fundamental assumptions that were the stock in trade of energy experts during the previous ten years. This document is a collection of papers representing responses to concerns prepared by current and former World Bank staff. Although these papers raise a variety of different concerns, a common theme that runs throughout the paper is the need to continue the pursuit of efficiency goals in the energy sector. The developing world still needs large amounts of capital to meet its ever-expanding energy requirements. These capital requirements will be a significant part of most countries'total investment plan. Given the problems of debt and public revenues, the report concludes that the pursuit of efficiency is just as important under lower fuel prices as it is under rising fuel prices.Power&Energy Conversion,Urban Environment,Environmental Economics&Policies,Energy Demand,Energy and Environment

    Social Purposes of Art Education

    Get PDF
    In very broad terms, I wish to address the social purposes of art and art education in an historical context, assuming that art education\u27s purposes extend to some extent from those of art. I will discuss these social purposes in the framework of major historical divisions: the tribal society, the agricultural community, industrial civilization, and the future scientific planetary community, or new age

    Artificial Recharge of Groundwater as a Water Management Option for Eastern Maine

    The declining population of Atlantic salmon in eastern Maine has brought the wild blueberry industry\u27s irrigation practice of pumping water directly from ponds and streams under scrutiny. Restrictions on pumping from streams has prompted the industry to seek new water resources. One resource with potential to assist the industry to meet its irrigation needs is groundwater. However, preliminary research has shown that groundwater is not capable of completely satisfying irrigation needs. To evaluate the potential that artificially recharging the groundwater during spring run-off to retain the water for later use as irrigation, the groundwater software Visual MODFLOW was applied. Inputs necessary to describe the hydrogeologic properties of the Pineo Ridge delta in Washington County, Maine were made. Once calibration was achieved, the model was used to simulate the effects that the artificial recharge of groundwater (ARG) had on the hydrodynamics of the system. Water was recharged into the aquifer during April and May (225 Lls (4050 gpm) for 45 days) when spring flows generally make water available in nearby ponds, streams, and rivers. Then, in July and August when water is limited and needed for irrigation, the water was removed from the aquifer by pumping. The study site shows potential in that it was capable of supporting 7 pumping wells for 80 days at 8 L/s (125 gpm) each. Once the potential of the Pineo Ridge recharge site had been evaluated, three of the hydrogeologic parameters; hydraulic conductivity, storativity, and distance to a surface-water body, of the aquifer were adjusted to determine the impact that each had on the groundwater system. The goal of this evaluation was to determine the extent that each controlled the overall success or failure of an ARG site. Finally, the values for the parameters that yielded the most favorable results were applied to one simulation. Again, recharge was applied at 225 L/s (4050 gpm) for 45 days during April and May. The resulting simulation characterized an aquifer system capable of supporting 10 wells each yielding 12.8 L/s (200 gpm) for 80 days without reducing the groundwater table in the aquifer by more than 30 cm (1 ft) from observed elevations. From this study some general guidelines with which to evaluate potential ARG sites were determined. Aquifers with hydraulic conductivity values between le-4 m/s (30 ft/day) and 1.8e-4 m/s (50 ft/day) have the greatest potential for this application. Recovery of water through pumping is difficult in aquifers with specific yield values less than 0.2. Finally, the extent that the distance between the recharge site and a nearby surface-water body might assist or hinder the blueberry producers ability to recover the recharged water needs to be evaluated on a case-bycase basis

    Hugh M. Kindred: A Tribute

    Get PDF
    We are pleased to introduce this special issue of the Dalhousie Law Journal, which is essentially a mini-festschriftin honour of Professor Hugh Kindred. Hugh began teaching at what was then Dalhousie Law School in 1971 and retired from full-time teaching in 2008, with a well-deserved Professor Emeritus status bestowed on him in 2010. In between Hugh provided wisdom, quiet counsel and gracious generosity to generations of students and faculty at what is now called the Schulich School of Law, and became a pillar of the Canadian legal academic community. His legacy is enormous and ongoing, as Hugh has continued to be active in both teaching and research since his retirement

    Unsupervised Learning with Self-Organizing Spiking Neural Networks

    We present a system comprising a hybridization of self-organized map (SOM) properties with spiking neural networks (SNNs) that retain many of the features of SOMs. Networks are trained in an unsupervised manner to learn a self-organized lattice of filters via excitatory-inhibitory interactions among populations of neurons. We develop and test various inhibition strategies, such as growing with inter-neuron distance and two distinct levels of inhibition. The quality of the unsupervised learning algorithm is evaluated using examples with known labels. Several biologically-inspired classification tools are proposed and compared, including population-level confidence rating, and n-grams using spike motif algorithm. Using the optimal choice of parameters, our approach produces improvements over state-of-art spiking neural networks

    The Role of State and Local Government in the Economic Development of Appalachia

    Get PDF
    One dimension of development planning for Appalachia which has been given little attention is the potential role of state and local governments. That is, what taxation and expenditure policies are most harmonious with the goals of economic development? The dual objectives of this paper are to examine the trend and pattern of finances shaped by the state and local government sector in an underdeveloped Appalachian state, and to explore the implications of alternative public (state- local) policies for economic growth
