从数到形--悖论与数学对象的转移

古希腊人的数学兴趣似乎专注于几何方面,导致这种现象有多种原因。而数学史昭示,古希腊人对数学对象从数转移到形,实质从逻辑转移到直观,主要是由于古希腊人发现了所谓不可表达的数或不可公度比.     

"大地"托起"珍珠""珍珠"辉映"大地"--刍议赛珍珠及其代表作《大地》

赛珍珠之所以成为第一位获得诺贝尔文学奖的美国女作家,是因为她的代表作《大地》继承了中国优秀的文化遗产与写作特色,为读者编织了一幅旧中国农村社会广阔、独特的民俗长卷,成为西方读者了解中国的必读书,赋予了西方一个全新的、有血有肉的中国形象。她向西方介绍中国文化,试图运用中国人的视角,以文化为切入点描写中国农村和城镇生活,架起了东西方文化交流的桥梁。随着中美两国、东西方跨文化交流的日益频繁,她的作品将再次发出夺目的光辉。

Narrating Childhood in Elena Chizhova’s Vremya zhenshchin

ABSTRACT

This article discusses the representation of the Soviet past through the figure of a child in Elena Chizhova’s novel Vremja ?en??in [Vremya zhenshchin] (2009). The concept of the vulnerable subject is applied to conceptualize the narrative’s ‘access’ to the past. Vremja ?en??in [Vremya zhenshchin] tells the story of a mute girl raised by her mother and three ‘grandmothers’ in 1960s Leningrad. The women decide to keep her muteness as a secret in order to protect her from being sent to a state institution for disabled children, and to raise her at home. The child figure is situated on the verge of two value systems: the collective, secular, and modern value system, represented by the outside world of home; and the private, spiritual, and traditional value system represented by the community of three old women. The position of the vulnerable child figure on the margins of society enables the representation of a ‘lost’ past and its alternative values. The article suggests that the vulnerable child figure can be seen to stand for a feeling of loss and abandonment in more general terms in contemporary Russia, and as representing a search for a lost inheritance.     

The Kalman Filter from the Perspective of Goldberger—Theil Estimators

This article is designed to point out the close connection between recursive estimation procedures, such as Kalman filter theory, familiar to control engineers, and linear least squares estimators and estimators that include prior information in the form of linear restrictions, such as mixed estimators and ridge estimators, familiar to statisticians. The only difference between the two points of view seems to be a difference in terminology. To demonstrate this point, it is shown how the Kalman filter equations can be derived from an existing textbook account of linear least squares theory and the notion of combining prior information in linear models, that is, the Goldberger—Theil mixed estimators' point of view. The author advocates the inclusion of these ideas early when least squares estimation concepts are being taught.
