Bilingual Mathematics

在加拿大。有人讲英语,有人讲法语,于是加拿大就将英语和法语都定为自己的官方语言。其实,加拿大不仅仅在官方语言上实施“一国两制”,在度量单位上也是公制和英制交替使用。这给加拿大人生活带来了些许不便。Brad也常为之头疼。     

Driving in China

Brad夫妇今年来中国故地重游。看到如今城市里满大街的汽车代替了20年前比比皆是的自行车,感慨之余,也对中国马路上的交通状况甚是担忧。     

The Sorrows of Being Young

编者按：年轻,固然令人羡慕,却也是个容易彷徨困惑的年纪。脚下的路似乎很长,但到底会伸向何方？又该如何去走？Brad给出了他中肯的建议。     

The effects of short versus long inter-set rest intervals in resistance training on measures of muscle hypertrophy: A systematic review

Although the effects of short versus long inter-set rest intervals in resistance training on measures of muscle hypertrophy have been investigated in several studies, the findings are equivocal and the practical implications remain unclear. In an attempt to provide clarity on the topic, we performed a systematic literature search of PubMed/MEDLINE, Scopus, Web of Science, Cochrane Library, and Physiotherapy Evidence Database (PEDro) electronic databases. Six studies were found to have met the inclusion criteria: (a) an experimental trial published in an English-language peer-reviewed journal; (b) the study compared the use of short (≤60?s) to long (>60?s) inter-set rest intervals in a traditional dynamic resistance exercise using both concentric and eccentric muscle actions, with the only difference in resistance training among groups being the inter-set rest interval duration; (c) at least one method of measuring changes in muscle mass was used in the study; (d) the study lasted for a minimum of four weeks, employed a training frequency of ≥2 resistance training days per week, and (e) used human participants without known chronic disease or injury. Current evidence indicates that both short and long inter-set rest intervals may be useful when training for achieving gains in muscle hypertrophy. Novel findings involving trained participants using measures sensitive to detect changes in muscle hypertrophy suggest a possible advantage for the use of long rest intervals to elicit hypertrophic effects. However, due to the paucity of studies with similar designs, further research is needed to provide a clear differentiation between these two approaches.     

道德规范与国书馆事业

美国图书馆协会的<职业道德规范声明>提出了以图书馆事业为中心的具体原则,其<图书馆权利法案>则明确了图书馆的责任和义务.目前,美国社会和政治环境的变化为图书馆职业带来了越来越多的忧虑和压力."9·11"后出台的<爱国者法案>明显与图书馆职业道德规范中所阐述的重要原则相冲突.因此,美国图书馆协会决心抵制<爱国者法案>对知识、信息自由开放以及行使个人隐私权的限制.     

运气可以差，勇气不能丢

关于李坚柔的夺金,说是奇迹也好、邪门也罢,不可否认运气闪索真的占了很大成分。可以说,竞技体育的魅力和残酷都集中在这里。我们时常会感叹：他不过是差了一点点运气;又或者对谁一哂：不就是运气好点么。每当说到运气,我们难免会带有一些无奈．和一丝不忿。     

濒危的忠诚

这赛季英超到目前为止,给我印象最深刻的镜头只有一个,就是兰帕德代表曼城攻破老东家切尔西的球门。赛前人们都猜想着这一幕发生的种种后果,但兰帕德进球的那一刻,球场上的蓝军球迷和球员都木然了,连我这个坐存电视机前看球的人都不知道说什么,翻一翻蓝军的球迷论坛,没有辱骂,也没有赞扬,有一个球迷的留言间我心有戚戚：感觉怪怪的。
