The industrial connections in Donald Judd's art

This paper examines the context and impact of the industrial materials and processes of the mid-twentieth century on Donald Judd's works, focusing on galvanized steel, cellulose nitrate paints, anodizing, and the RAL color matching system. Exploration of the industrial materials and methods Judd utilized provides a greater understanding of his processes, choices, and ultimately his art, its care, and legacy.     

远程开放教育成本与效益分析

理解:开放、融合与扩充--试析加达默尔诠释学中的理解问题

加达默尔的诠释学从一个全新的角度论述了理解问题,使哲学诠释学成为一个独立的哲学流派,在现代西方哲学史上产生了巨大的影响。他认为理解是此在本身的存在方式;理解具有历史性;理解按其本性乃是一种效果历史事件,而视域融合又是对效果历史的展示和具体说明。因此,理解效果历史原则是把握加达默尔理解问题的关键。     

汉语"道歉"话语模式

道歉是交际中的一种补救性施事言语行为，也是一种礼貌的社会行为。其基本功能是为一项冒犯行为提供补救办法，恢复社会平衡与和谐。从语言形式来看，道歉具有语义句法程式化和规约化的普遍特征。本用语篇补全测试的问卷形式通过对汉语中道歉行为实施的调查、对所选策略进行了分类统计，结果表明道歉的话语模式包括多种策略和手段的组合，但策略的选用在很大程度上受到如权势、距离等因素的制约，说明道歉行为对化等因素的依赖。     

绿色化学浅谈

化学工业在给人类带来丰富的新产品的同时，也给人类带来了严重的环境污染。于是，绿色化学应运而生，绿色化学的理想在于不再使用有毒、有害的物质，不再产生废物，不再处理废物，它是一门从源头上阻止污染的化学。本文简要介绍了绿色化学的起源、特点、原则和研究进展。     

构建以学习为中心的远程开放教育管理机制

远程开放教育是利用网络技术、多媒体技术等现代信息技术手段开展起来的新型教育形式。在“人才培养模式改革和开放教育试点”工作之中,笔者发现远程开放教育的管理机制的改革调整势在必行。本文对远程开放教育管理模式、组织结构、教学策略等管理体制做了有益的探讨。     

One hundred and fifty years of sprint and distance running – Past trends and future prospects

Sprint and distance running have experienced remarkable performance improvements over the past century. Attempts to forecast running performances share an almost similarly long history but have relied so far on relatively short data series. Here, we compile a comprehensive set of season-best performances for eight Olympically contested running events. With this data set, we conduct (1) an exponential time series analysis and (2) a power-law experience curve analysis to quantify the rate of past performance improvements and to forecast future performances until the year 2100. We find that the sprint and distance running performances of women and men improve exponentially with time and converge at yearly rates of 4% ± 3% and 2% ± 2%, respectively, towards their asymptotic limits. Running performances can also be modelled with the experience curve approach, yielding learning rates of 3% ± 1% and 6% ± 2% for the women's and men's events, respectively. Long-term trends suggest that: (1) women will continue to run 10–20% slower than men, (2) 9.50 s over 100 m dash may only be broken at the end of this century and (3) several middle- and long-distance records may be broken within the next two to three decades. The prospects of witnessing a sub-2 hour marathon before 2100 remain inconclusive. Our results should be interpreted cautiously as forecasting human behaviour is intrinsically uncertain. The future season-best sprint and distance running performances will continue to scatter around the trends identified here and may yield unexpected improvements of standing world records.     

中国现代远程教育质量论略

远程教育的教学质量应该由开展远程教育的机构、参加远程教育的学习者、社会来认可,而三者对教育质量的标准的认同必须统一。认定远程教育的质量标准是一项较为复杂的工作,需要经过科学研究,由国家权威部门制定或由行业制定国家认可的标准,同时由相关部门组成专家对开展远程教育的机构、学院进行经常性的评估。
