The Use of Graduated Scenarios to Facilitate the Learning of Complex and Difficult-to-describe Concepts

There are many complex concepts in higher education learning that are difficult to convey to learners in words. Some examples are reflective learning, critical thinking, clinical reasoning; processes of evaluation (e.g. in art and design subjects) and professional practice (eg teaching itself). These are important concepts that evade straight forward uses of language that might explain how to ‘do’ them and how then to ‘do them better’ or at a ‘deeper level’ and so on. This paper explores a method that has been developed to facilitate the learning of such concepts - the graduated scenario technique. The paper describes the initial development of the method with respect to the concept of reflective learning. Graduated scenarios are based on two practices – firstly, the use of examples and demonstrations that show learners – in this case - how to write reflectively. Secondly they demonstrate the characteristics of deep reflection as opposed to superficial and descriptive reflection. This demonstration is made explicit at the end of the exercise, in a framework for,– in this case, reflective learning. The assumption is made that better quality learning emanates from deeper reflection (eg Hatton and Smith, 1995). The paper goes on to discuss the application of the graduated scenario technique to critical thinking. It then moves to a more generic approach, considering why such the technique appears to be helpful - and it provides examples of other areas of learning in which the it could be used

Communication performance over the TDRS multipath/interference channel

Previously developed models are used to predict communication system performance for two cases: and aircraft/TDRS and a weather satellite/TDRS relay. The magnitude of multipath, differential time delay, Doppler shift, time and Doppler spread, and interference expected to be encountered are reviewed and applied to the two cases of interest

Clergy work-related psychological health : listening to the Ministers of Word and Sacrament within the United Reformed Church in England

Drawing on the classic model of balanced affect proposed by Bradburn (The structure of psychological well-being, Aldine, Chicago, IL, 1969), this study conceptualised poor work-related psychological health in terms of high levels of negative affect in the absence of acceptable levels of positive affect. In order to illuminate self-perceptions of work-related psychological health among a well-defined group of clergy, a random sample of 58 ministers of word and sacrament serving within the west midlands synod of the United Reformed Church in England completed an open-ended questionnaire concerned with the following six guiding questions. Do you enjoy your work? How would you define stress? How would you define burnout? What stresses are there in your ministry? What do you do to keep healthy? What can the church do to enhance the work-related psychological health of ministers? Content analysis highlighted the main themes recurring through these open-ended responses. The conclusion is drawn that ministers of word and sacrament within the United Reformed Church in England are exposed to a number of recurrent recognisable sources of stress. Suggestions are advanced regarding the need for future more detailed research and for the development of more effective pastoral strategies

PDF model based on Langevin equation for polydispersed two-phase flows applied to a bluff-body gas-solid flow,

The aim of the paper is to discuss the main characteristics of a complete theoretical and numerical model for turbulent polydispersed two-phase flows, pointing out some specific issues. The theoretical details of the model have already been presented [Minier and Peirano, Physics Reports, Vol. 352/1-3, 2001 ]. Consequently, the present work is mainly focused on complementary aspects, that are often overlooked and that require particular attention. In particular, the following points are analysed : the necessity to add an extra term in the equation for the velocity of the fluid seen in the case of twoway coupling, the theoretical and numerical evaluations of particle averages and the fulfilment of the particle mass-continuity constraint. The theoretical model is developed within the PDF formalism. The important-physical choice of the state vector variables is first discussed and the model is then expressed as a stochastic differential equation (SDE) written in continuous time (Langevin equations) for the velocity of the fluid seen. The interests and limitations of Langevin equations, compared to the single-phase case, are reviewed. From the numerical point of view, the model corresponds to an hybrid Eulerian/Lagrangian approach where the fluid and particle phases are simulated by different methods. Important aspects of the Monte Carlo particle/mesh numerical method are emphasised. Finally, the complete model is validated and its performance is assessed by simulating a bluff-body case with an important recirculation zone and in which two-way coupling is noticeable.Comment: 23 pages, 10 figure

The relationship between recalled self-esteem as a child and current levels of professional burnout among Anglican clergy in England

This study links and tests three strands of theory concerned with explaining individual differences in levels of professional burnout in general and among religious professionals in particular. These three strands concern the significance of current self-esteem, recalled self-esteem as a child, and personality. Data were provided by a sample of 1,278 male stipendiary parochial clergy working in the Church of England who completed the modified Maslach Burnout Inventory (specially designed for use among clergy), and the short-form Revised Eysenck Personality Questionnaire (designed to measure the personality dimensions of extraversion, neuroticism and psychoticism), together with a semantic differential index of recalled self-esteem as a child. The bivariate correlation coefficients demonstrated significant associations between more positive self-esteem as a child and lower levels of professional burnout (higher personal accomplishment, lower emotional exhaustion and lower depersonalisation). The bivariate correlation coefficients also demonstrated significant associations between personality and professional burnout. Multiple regression analyses, however, demonstrated that the association between recalled self-esteem as a child and professional burnout largely disappeared after controlling for the personality variables. The conclusion is drawn that knowledge about the personality profile of clergy functions as a more secure predictor of susceptibility to professional burnout than knowledge about recalled self-esteem as a child

Rasio Keuangan dan Prediksi Financial Distress

The purpose of this research is to understand the effect of financial ratios in predicting the possibility of financial distress on companies listed on Sri Kehati index in a row of 2009-2016. This study uses the financial ratios proxied by return on assets, return on capital, net profit margin, P / E ratio, and asset turnover as independent variables. Meanwhile, the financial distress proxied by Z-score is a dependent variable. The population of this study is all companies listed on the index of Sri Kehati in 2009-2016 and listed on the Indonesia Stock Exchange. The sample of this study took nine companies with purposive sampling method and the study period is for eight years in a row (2009-2016). Logistic regression method used in this research. The results show that ROA, ROE and PER have a significant effect on financial distress. Meanwhile, NPM and ATO have no significant effect on financial distress

The MASSIVE Survey II: Stellar Population Trends Out to Large Radius in Massive Early Type Galaxies

We examine stellar population gradients in ~100 massive early type galaxies spanning 180 < sigma* < 370 km/s and M_K of -22.5 to -26.5 mag, observed as part of the MASSIVE survey (Ma et al. 2014). Using integral-field spectroscopy from the Mitchell Spectrograph on the 2.7m telescope at McDonald Observatory, we create stacked spectra as a function of radius for galaxies binned by their stellar velocity dispersion, stellar mass, and group richness. With excellent sampling at the highest stellar mass, we examine radial trends in stellar population properties extending to beyond twice the effective radius (~2.5 R_e). Specifically, we examine trends in age, metallicity, and abundance ratios of Mg, C, N, and Ca, and discuss the implications for star formation histories and elemental yields. At a fixed physical radius of 3-6 kpc (the likely size of the galaxy cores formed at high redshift) stellar age and [alpha/Fe] increase with increasing sigma* and depend only weakly on stellar mass, as we might expect if denser galaxies form their central cores earlier and faster. If we instead focus on 1-1.5 R_e, the trends in abundance and abundance ratio are washed out, as might be expected if the stars at large radius were accreted by smaller galaxies. Finally, we show that when controlling for \sigmastar, there are only very subtle differences in stellar population properties or gradients as a function of group richness; even at large radius internal properties matter more than environment in determining star formation history.Comment: 17 pages, 9 figures, accepted by ApJ; resubmitted with updated reference
