一道早期冬令营试题的推广

文[1]给出了第三届冬令营第一题的导数解法，文章结尾提到“可以推广到更一般的情况”．下面就来研究一下更一般的情况．     

一道早期冬令营试题的导数解法

题目设a1，a2，…，an是给定的不全为0的非负实数，r1，r2，…，rn都是非负实数，使得不等式∑k=1^nrk（xk-ak）≤（∑k=1^nxk^2）^1/2-（∑k=1^nak^2）^1/2①对任意非负实数x1，x2，…，xn都成立．求r1，r2，…，rn的值．[第一段]     

一道冬令营试题的推广

题目在Rt△ABC中,∠ACB=90°,△ABC的内切圆⊙O分别与边BC、CA、AB相切于点D、E、F,联结AD,与内切圆⊙O相交于点P,联结BP、CP.若∠BPC=90°,求证:AE+AP=PD.(2006,中国数学奥林匹克)本文指出,对任意三角形,类似的结论都成立.命题在△ABC中,设内切圆⊙O分别与边BC、CA、AB相切于点D、E、F,联结AD,与内切圆⊙O相交于点P,联结BP、CP.则∠BPC=90°的充要条件是AE+AP=PD.引理1自⊙O外一点A作⊙O的切线AE及割线APD(AP相似文献

桑塔格坎普后现代主义

后现代主义既是一种思潮,也是一种观念,一种生活态度,一种思想倾向。利用桑塔格的“坎普”的阐释来解说,它还是一种感觉方式和感受力。这种观念、态度、倾向或者说是感受力与其说是对于传统思潮的抵抗,不如说是恰当的思想规避,在规避和些微的调侃中重新厘定个人的地位和价值。如果采用了“坎普”的做派,那就成为了一种张扬和探讨,期待求得社会认知和个性发现。很多的坎普和很多的后现代做派是不自觉的,是逐渐的大众文化交流给予的传染,它们表现在具有不同意识形态倾向的人士们身上,只不过方式有些不相同而已。后现代主义思潮不是洪水猛兽,也不是救世方案,它其实就是我们的生活本身。

Social Work Students Go to Camp

Abstract

This study explored the effects of an intensive, service learning course on the perceived self-efficacy of participating MSW students. A self-efficacy scale was developed following Bandura's (1977) model, based on the goals and objectives of the MSW program and was administered pre and post. The findings indicated a statistically significant increase in perceived self-efficacy (p< .001) following completion of the course. In addition, the students demonstrated significant increases in self-efficacy related to mezzo (p< .001) and macro-level skills (p< .001). These results suggest that service learning, underutilized in social work education, may be an effective learning approach in master's level programs.     

Futoko and Camp Programs in Japan

Although Japanese education is compulsory up to the ninth grade, there are students who do not or cannot go to schools. They are referred long-term school absentees, or futoko students. They tend to have lower social communication skills and self-concepts than non-futokostudents. To develop these elements, outdoor activities have been found as an effective method provided by either public or private organizations. This paper aims to introduce the futokophenomenon within Japanese culture, and to analyze the organizations' philosophies and their program methods. According to the result, all organizations' major objectives are the development of social communication skills and self-concepts. An issue of parental participation with their futoko children is controversial. The perception on school attendance varies among organizations. To create effective and beneficial programs, it is important to apply objective research method. For that, it is crucial for both researchers and organizations to collaborate for assuring and improving of the quality of programs.

《印第安人营地》解读

《印第安人营地》是海明威早期创作中最为精致的小说之一,是一个比较复杂的文本。通过对文本的解读,可以发现一些我们过去忽略的重要内容。如文本中的种族文化冲突因素及男性形象类型。这也许能够为海明威的整体研究提供一点启示。     

“保研夏令营”的社会学分析

“保研夏令营”作为重点大学尤其是名校研究生自主招生的一种方式,能够多样化选拔优秀生源。但由于制度、权力和资本等因素的合谋,夏令营将普通院校毕业的考生排斥在外的行为不仅加大了研究生入学机会的失衡,忽视了研究生招生考试作为社会阶层流动的渠道、社会公平的手段等作用,而且研究生生源结构的失衡将加剧地区发展失衡。认为优化高等教育分层缩小阶层差距、合理配置高等教育资源促进学术繁荣、打破地域分据格局确保区域经济协调发展是“保研夏令营”摆脱目前困境的出路。
