Self-Direction, Values and Truth: Towards an Unpostmodern Re-examination     

David Carr 《Journal of Philosophy of Education》2000,34(2):297-312

Despite its exalted status in post-war analytical educational philosophy as probably the main aim of liberal education, the basic philosophical psychology of autonomy or self-determination is prey to certain not widely acknowledged conceptual difficulties. In relation to this problem, the present paper explores different conceptions of evaluation and competing liberal and communitarian conceptions of rational choice and decision, to the ultimate end of defending a crucial connection—discerned by many ancient and modern philosophers—between rational self-direction and the possibility of objective knowledge and truth.  相似文献   

The influence of gravimetric moisture content on studded shoe–surface interactions in soccer     

James Clarke  Matt J. Carré 《Sports Engineering》2017,20(2):121-132

It is desirable for the studs of a soccer shoe to penetrate the sport surface and provide the player with sufficient traction when accelerating. Mechanical tests are often used to measure the traction of shoe–surface combinations. Mechanical testing offers a repeatable measure of shoe–surface traction, eliminating the inherent uncertainties that exist when human participant testing is employed, and are hence used to directly compare the performance of shoe–surface combinations. However, the influence specific surface characteristics has on traction is often overlooked. Examining the influence of surface characteristics on mechanical test results improves the understanding of the traction mechanisms at the shoe–surface interface. This allows footwear developers to make informed decisions on the design of studded outsoles. The aim of this paper is to understand the effect gravimetric moisture content has on the tribological mechanisms at play during stud–surface interaction. This study investigates the relationships between: the gravimetric moisture content of a natural sand-based soccer surface; surface stiffness measured via a bespoke impact test device; and surface traction measured via a bespoke mechanical test device. Regression analysis revealed that surface stiffness decreases linearly with increased gravimetric moisture content (p = 0.04). Traction was found to initially increase and then decrease with gravimetric moisture content. It was observed that: a surface of low moisture content provides low stud penetration and therefore reduced traction; a surface of high moisture content provides high stud penetration but also reduced traction due to a lubricating effect; and surfaces with moisture content in between the two extremes provide increased traction. In this study a standard commercially available stud was used and other studs may provide slightly different results. The results provide insight into the traction mechanisms at the stud–surface interface which are described in the paper. The variation between traction measurements shows the influence gravimetric moisture content will have on player performance. This highlights the requirement to understand surface conditions prior to making comparative shoe–surface traction studies and the importance of using a studded outsole that is appropriate to the surface condition during play.  相似文献

Formative assessment in mathematics for engineering students     

Eabhnat Ní Fhloinn  Michael Carr 《European Journal of Engineering Education》2017,42(4):458-470

In this paper, we present a range of formative assessment types for engineering mathematics, including in-class exercises, homework, mock examination questions, table quizzes, presentations, critical analyses of statistical papers, peer-to-peer teaching, online assessments and electronic voting systems. We provide practical tips for the implementation of such assessments, with a particular focus on time or resource constraints and large class sizes, as well as effective methods of feedback. In addition, we consider the benefits of such formative assessments for students and staff.  相似文献   

An Aspect of the Infinite: New Zealand Talks     

David Carr 《Curator: The Museum Journal》2010,53(1):51-70

Fresh encounters with Māori treasures first seen by the author at the Metropolitan Museum in 1984 revealed the concentrated power of these objects and the importance of their presence among the beliefs and continuities of their makers’ culture. A masterwork viewed in a museum may evoke a strong and sometimes inarticulate response. We might say the inability to articulate reflects a larger dimension—an aspect of the infinite—residing in the object. Museum objects return us to the human culture and knowledge we carry with us; they stimulate reflective impulses essential to the shared threads of democracy. They allow us to locate ourselves and each other, and our shared horizons.  相似文献   

Characterising the impact performance of field hockey sticks   总被引：1，自引：1，他引：0  

Tom Allen  Leon Foster  Matt Carré  Simon Choppin 《Sports Engineering》2012,15(4):221-226

Published research on field hockey equipment is scarce. The aim of this research was to investigate methods for characterising the impact performance of field hockey sticks. Three sticks were used with fundamental frequencies in the range 74?C154?Hz. Striking an initially still ball with a stick was identified as the preferred method for characterising performance. Impacts were simulated at mean velocities of 19?m/s at toe and 16?m/s at the shaft. The mean apparent coefficient of restitution and standard deviation were ?0.32?±?0.05 at the toe and ?0.18?±?0.02 at the shaft. The foundation work presented here provides the foundations for developing a methodology for characterising the impact performance of field hockey sticks.  相似文献

A successful cross-training experience of reference service at UCLA     

Carr AF  Kawakami AK 《Medical reference services quarterly》2002,21(2):15-19

This paper describes a successful cross-training and reference librarian exchange experience involving two librarians at UCLA, one based at the Louise M. Darling Biomedical Library and the other based at the College Library, which primarily serves undergraduates. The experience has increased the reference skills and expertise of both librarians by introducing them to new sets of reference tools and databases, and has broadened their network of colleagues within the UCLA Library system. The participating libraries have also benefited from the exchange, and the program is expanding to include other UCLA libraries.  相似文献
