把爱寄绐我

这是一位即将退役的海军写给新婚妻子的书信。读罢,不禁想起了林觉民的《与妻书》,“窗外疏梅筛月影,依稀掩映,吾与汝并肩携手,低低切切,何事不语,何情不诉!……”两封“与妻书”,一中一外,一古一今,同中有异。新婚燕尔,分隔两地,借信笺传情,字里行间无不流露出浓情蜜意,这是两者的共同点。但由于所处时代以及环境等种种不同,两者又各有特色:海军的“与妻书”通过一系列的排比句细说深情和思念,将爱情的甜蜜和生活的幸福烘托得恰到好处;而林觉民的《与妻书》,确切说是“与妻诀别书”,却是一字一血泪,一语一悲恸!有心的读者不妨把两者对比来读,相信会有所感悟。——Maisie     

An ecological analysis of after-school program participation and the development of academic performance and motivational attributes for disadvantaged children

This longitudinal study evaluated after-school program (ASP) participation and the development of academic performance (school grades, reading achievement) and teacher-rated motivational attributes (expectancy of success, effectance motivation) over a school year. Participants were 599 boys and girls (6.3 to 10.6 years) from an urban, disadvantaged city in the United States. An ecological analysis of after-school arrangements identified 4 patterns of care: ASP care, parent care, combined parent/self-sibling care, and combined other-adult/self-sibling care. Aspects of academic performance and motivational attributes were significantly higher (p<.05) at the end of the school year for children in ASP care compared with those in the 3 alternative patterns of care. Differences were marked for children rated as highly engaged in ASP activities.

The history of lamaze continues: an interview with elisabeth bing

Elisabeth Bing-physiotherapist, childbirth educator, and cofounder of the American Society for Psychoprophylaxis in Obstetrics (now Lamaze International)-is well known to most childbirth educators in the United States. She has been a true pioneer in the education of parents for pregnancy and birth. Her book, Six Practical Lessons for an Easier Childbirth, served to guide many parents and childbirth educators in the use of the Lamaze Method for labor and birth. She has prepared a countless number of parents for their birth experience in both her hospital classes in the 1950s and 1960s and in her private classes in the "studio" of her New York City apartment building, where she began teaching in the 1960s and continues to teach today. Elisabeth is beloved by all those who have had the opportunity to meet her or work with her. She has created a legacy that will continue for decades to come.     

计划出走

克劳迪娅知道自己决不可能采用传统的那种背着背包,然后怒气冲冲离家出走的模式.她讨厌不舒服的感觉,连野餐时的不干净和不便,都令她无法忍受.草丛间四处飞舞的昆虫,以及被炙热的阳光融化掉的小蛋糕上的奶油……这些都足以让她发疯.因此,她决定这次离家出走不仅仅是从某个地方逃走而已,她要逃到一个更大、更舒服的地方,而且必须是室内,最好是个美丽的地方.……     

综合学习的蓝图(上)——四元教学设计模式

本文对四元教学设计模式做出概述。该模式最初是由范梅里恩伯尔等人在20世纪90年代初期为设计综合能力的培训项目而开发的。本文论述了综合学习培训蓝图的结构及相应的教学方法,其基本观点是:学习任务、相关知能、支持程序和专项操练这四个彼此关联的元素,在综合学习蓝图中是必不可少的。文章讨论了与涉及综合能力有关的基本学习过程相匹配的教学方法,同时提供了"检索文献"培训蓝图的样例。     

一个有趣的数字游戏——用代数来解释

问题的提出请一个学生不让你看见做如下事情: 1) 任意写一个比20大的自然数, 2) 把这个数的各位数字加起来, 3) 从原来的数中减去这个和数, 4) 再从差数中划掉任意一位数字(即便这个数字在数中出现不止一次,也只划去一位),

Development of Shallow Footing Anti-Ram Bollard System Through Modeling and Testing

In past terrorist attacks, vehicle borne improvised explosive devices (VBIED) have been the primary manner of attacking buildings and infrastructures. Preventing unauthorized vehicles from approaching a protected area with anti-ram systems would maintain an established standoff distance against moving and stationary vehicles and consequently reduce blast and debris threats. This strategy has been considered the first line of defence against terrorists. Several types of anti-ram devices have been developed in accordance with U. S. Department of State K-rating criteria, for example, wedge barriers, rising beams, sliding/swing gates, and drop arms. However, these devices typically need a deep foundation for installation and can't be implemented into many locations where a depth of excavation is limited in order to protect utility lines of buildings and infrastructures. This paper presents a recent development of a series of shallow footing anti-ram bollard systems (SFABS) that can satisfy K-12 rating with only five-inch thick footing. A high-fidelity physics based finite element technique with a vehicle crash model is used for predicting anti-ram capacity and determining design parameters of the SFABS. Full-scale vehicle crash tests of the developed SFABS systems have been carried out to validate the design and analysis.     

隐蔽课程探析

被隐蔽起来的事物是难以发现或界定的。各种各样的作者试图对“隐蔽课程”这个术语所包含的意义作出各自的解释。在一次关于课程“本质”的讨论中,道格拉斯·巴恩斯(DougLas Barnes)用隐蔽课程这个术语表示非预期的结果,正如人们所宣称的那些意思。象罗宾·巴罗(Robin Barrow)这样一些学者并不想把关于隐蔽课程的推论包含在课程自身
