Journals Pricing     

Kraig Adler  Wally Olsen 《Learned Publishing》1999,12(2):137-139

A significant new study has been conducted at Cornell University. The Mann Library surveyed several hundred titles in Agriculture and Biology, in order to analyse their prices (per page and per thousand characters) over time, comparing university presses, commercial publishers, society publishers and government agencies. They aimed to develop a methodology, using Optical Character Recognition (OCR) technology, which could be used elsewhere, and to use their findings to examine the patterns of article ownership and pricing of published scientific research.  相似文献

工学结合人才培养模式下高职思政教育刍议     

贾涛 《宁波职业技术学院学报》2011,(4):20-23

工学结合人才培养模式下的高职思想政治教育工作既有许多有利因素,又充满挑战。有利因素是：理论与实践相融,有利于增强教育效果;校企文化对接,有利于提高学生的职业素养;工学结合,有利于增强学生的社会适应能力。面临的挑战有：教育者、受教育者、教育环境、教育内容和方法等发生了变化。因此,要转变观念、更新内容、采取适当方法,以适应这种新型人才培养模式下的思想政治教育工作。  相似文献   

Pre-exercise antioxidant enzyme activities determine the antioxidant enzyme erythrocyte response to exercise     

P Tauler  A Aguiló  P Guix  F Jiménez  G Villa  JA Tur 《Journal of sports sciences》2013,31(1):5-13

Free radical production increases during exercise and oxidative damage occurs in several tissues. We examined the effects of three different exercise tests on the pattern of change of erythrocyte enzyme antioxidant activities. The tests were a short maximal exercise test, a submaximal prolonged exercise test and a cycling stage during competition. The participants were amateur and professional cyclists with different training statuses and different basal erythrocyte antioxidant enzyme activities. The maximal test produced no changes in the erythrocyte antioxidant enzyme activities of amateur sportsmen. The submaximal test, performed at 80% of maximal oxygen uptake, decreased erythrocyte catalase (12%), glutathione peroxidase determined with H₂O₂ (14%) and glutathione reductase (16%); superoxide dismutase activity increased by about 25%. The cycling stage performed by professional cyclists increased erythrocyte catalase (29%) and glutathione reductase (10%) activities. The in vivo changes in glutathione reductase activity were confirmed by in vitro measurements: hydrogen peroxide decreased and the presence of catalase increased the activity of this enzyme. In conclusion, we suggest that the different erythrocyte antioxidant enzyme responses to diverse exercise tests can be explained by the effects of hydrogen peroxide and the superoxide anion on the antioxidant enzyme activities in erythrocytes.  相似文献
