    eModeration: Contextualising online learning in undergraduate nurse education

    Get PDF
    The wide availability of flexible, mixed-mode methods of course delivery to nursing students places increased demands on the skills and adaptability of nurse educators. The rapid uptake of computer-moderated learning, in particular, has required educators to reconsider some of their long-established pedagogical beliefs and practices which, over time, have faithfully sustained face-to-face teaching in classrooms. Inevitably, a certain degree of pedagogical adjustment is required when teaching online to ensure that the qualities of educational processes are consonant with expected learning outcomes. This paper discusses these important aspects, together with strategies that can help optimise educational practice, with a view to improve the delivery of Web-based courses

    The Burden of Knowing: Camus, Qohelet, and the Limitations of Human Reason

    In one of the most influential works of the twentieth century, The Myth of Sisyphus, Albert Camus writes this: “This heart within me I can feel, and I judge that it exists. This world I can touch, and I likewise judge that it exists. There ends all my knowledge, and the rest is construction.” Here, Camus addresses what he believes to be one of the main sources of the absurd: the limitations of human reason. He claims that his inability to fully understand human reality creates a gap between his existence and its meaning, and, in effect, renders the whole of human experience as absurd. Because Camus makes these conclusions from a purely atheistic position, it would seem that his notion of the absurd is incompatible with a theistic understanding of the human condition. Interestingly, however, the main speaker of the ancient Hebrew wisdom book Ecclesiastes, Qohelet, also concludes that the limits of human knowledge give life a sense of absurdity. Although Camus (an atheist) and Qohelet (a theist) begin with different assumptions regarding the existence of God—the very Being who gives meaning and clarity to his creation—their similar conclusions reveal an unlikely compatibility between atheistic and theistic attitudes towards the human predicament. While Camus and Qohelet recognize that the world cannot be explained by human reasoning, and is therefore absurd, they each conclude that uncertainty and human limitations may prompt a certain liberation and solace that allows them to move beyond the absurd. This curious parallel between Camus’s modern existential attitudes in The Myth of Sisyphus and the ancient Hebraic wisdom of Ecclesiastes show that the awareness of the limitation of human reason may compel man to live authentically and passionately despite the seeming unreasonableness of his life

    Modeling Particle Transport Distances as a Function of Slope and Surface Roughness

    Significant effort has been put into modeling the evolution of hillslope profiles through time. The models use a continuum approach and are commonly deterministic. Early models assumed a linear relationship between hillslope angle and sediment flux. This relationship produces hillslope profiles that increase in steepness from crest to base. However, hillslopes observed in the field are commonly planar downslope of their convex crests. Recently, non-linear sediment transport equations have been developed that produce hillslope profiles closer to those which are observed in nature, yet the mid-slope sections are not entirely planar. Currently, there is interest in using a non-deterministic approach where transport distances follow probability distributions that depend on hillslope angle. In order to qualitatively and quantitatively characterize this probabilistic relationship, the transport distances of individual particles released into a dry ravel flume with a rough surface were measured as a function of flume angle. Using the inputs of flume angle and surface roughness, the results of the experiments were replicated with a discrete element model in which the motion of the particles was modeled with the momentum equation. The implication of this study is that this method can be used with inputs measured from the field to model the evolution of entire hillslopes

    Finite element methods for integrated aerodynamic heating analysis

    Get PDF
    This report gives a description of the work which has been undertaken during the second year of a three year research program. The objectives of the program are to produce finite element based procedures for the solution of the large scale practical problems which are of interest to the Aerothermal Loads Branch (ALB) at NASA Langley Research Establishment. The problems of interest range from Euler simulations of full three dimensional vehicle configurations to local analyses of three dimensional viscous laminar flow. Adaptive meshes produced for both steady state and transient problems are to be considered. An important feature of the work is the provision of specialized techniques which can be used at ALB for the development of an integrated fluid/thermal/structural modeling capability

    The Impact of Insurance Prices on Decision-Making Biases: An Experimental Analysis

    Get PDF
    This paper tests whether the use of endogenous risk categorization by insurers enables consumers to make better-informed decisions even if they do not choose to purchase insurance. We do so by adding a simple insurance market to an experimental test of optimal (Bayesian) updating. In some sessions, no insurance is offered. In others, actuarially fair insurance prices are posted, and a subset of subjects is allowed to purchase this insurance. We find significant differences in the decision rules used depending on whether or not one observes insurance prices. Although the majority of choices correspond to Bayesian updating, the incidence of optimal decisions is higher in sessions with an insurance option. Most subjects given the option to purchase actuarially fair insurance choose to do so, however fewer subjects purchase insurance when the probability of a loss is higher. Working Paper 06-1

    FACTORS AFFECTING THE NUMBER AND TYPE OF SMALL-FARM DIRECT MARKETING OUTLETS IN MISSISSIPPI

    Get PDF
    The objective of this study was to delineate and measure the effects of selected economic demographic characteristics of Mississippi counties on the number and type of direct marketing of fruits and vegetables. A combination of primary data collected through a survey of county agents and secondary data from government sources were assembled to achieve the objective. Regression equations representing pick-your own marketing, farmerÂ’s' markets and farm stands were estimated with the iterative three stage least squares technique. Results indicated that economic factors such as income, employment, acreage, and demographic factors (e.g., total population of county, and the size of cities and towns within county boundaries) have varied impacts on the different types of direct marketing.Agribusiness,

    Finite element analysis of aerodynamic heating in three dimensional viscous high speed compressible flow: An assessment

    Get PDF
    The current capability of the finite element method for solving problems of viscous flow is reviewed. Much work has been directed to the simulation of incompressible flows and the relevant features are described. The methods available for, and the problems associated with, the finite element solution of high speed viscous compressible flows are analyzed. A plan for developing finite element research in this area with experimental support is presented
