Economic and technological changes converge on the connection between publishers and libraries. Arguing that the current library
budget crisis is clearly different from previous crises, Paula Kaufman describes changes in university environments and in
libraries’ strategies for coping with higher prices and strained budgets. Shifts in spending patterns from books to serials,
gaining access to materials by means other than purchasing them, overpublishing, technological transformations, and the entry
of new players into the scholarly publishing arena will all affect the ways that publishers publish and libraries acquire.
Paula T. Kaufman is dean of libraries at the University of Tennessee, Knoxville, and a member of the board of the Society
of Scholarly Publishing. 相似文献

Fermentation processes are virtually as old as civilisation itself but only within the past century have the underlying processes begun to be understood. Today, microorganisms are used to make a variety of industrial chemicals. 相似文献

The purpose of this study was to determine the effects of systematic changes in stride rate and length at a given running speed on the peak shank deceleration (PSD) experienced during ground contact. Data were collected from 10 well-trained subjects as they ran on a treadmill at a pace of 3.8 m s-1 (7-min mile-1). Shank deceleration was measured by a lightweight accelerometer which was tightly attached over the distal medial tibia. High-speed films (200 Hz) were taken from a side view to quantify modifications in sagittal plane movement which might have accompanied the stride rate changes. Five stride rate conditions were randomly presented - 10% slower, 5% slower, normal, 5% faster and 10% faster. Average PSD was computed from 10 steps during each condition and testing was repeated on three different occasions. For each session, PSD observed for each condition was normalized to that observed at the normal stride rate in order to minimize the effects of variations in attachment of the accelerometer between and within subjects. The normalized PSD results at each stride rate tested were - normal = 1.0, 10% slower = 1.09, 5% slower = 1.03, 5% faster = 0.96 and 10% faster = 0.91. Significant differences were found between all these means except normal and 5% slower. The kinematic analysis revealed non-significant results for hip, knee and ankle joint angles at touchdown for the various stride rates. Application of the findings to existing analytical models indicated that, for a given running speed, peak impact forces in the ankle and knee joints decreased as stride rate increased. 相似文献

This article reports a study designed to examine the mediating effect of vice-principals’ job satisfaction on the relation between their responsibility roles and career aspirations. Based on a Hong Kong data set, the study confirmed that responsibilities had both a direct effect and an indirect effect on career aspiration; the latter was mediated by job satisfaction. When specific responsibility dimensions were being considered, the two dimensions of leader and teacher growth and development, and teaching, learning, and curriculum were found to have an effect on job satisfaction, which in turn, influenced career aspiration. The dimension of Resource Management did not link to job satisfaction, it was however a predictor for career aspiration. Implications of the findings were discussed. 相似文献
