对班主任工作的思考

本文根据笔者工作中的实践经验,从“全面了解学生情况、培养学生自信心、建立良好班风、建立班集体目标、重视学生心理健康教育、做好学生思想工作、客观公平对待学生、重视素质教育、沟通学校、家庭、社会三方面的教育”九个方面分析论证了班主任工作是一项研究人、影响人、教育人和塑造人的系统工程,它在实现学校办学目的、教育目标、教学功能等方面起着非常重要的作用。     

多媒体热的冷思考

多媒体教学是近年来出现的新事物,他以其信息量大、画面直现、教学效率高等优点给高校教学带来了巨大变化。但也存在着互动性差、课件质量不高等弊端。认为应通过提高多媒体课的准入门槛、将多媒体技术与传统教学手段相结合、加强对多媒体课程质量和运行的检查等措施来解决。     

《读书人是幸福人》说课设计

说课,是检验教师教学基本功的手段之一,它不同于一般的发言稿和课堂教学,它要求说者比较系统地介绍自己的教学设计及其理论依据(包括大纲依据、课程标准依据、教学法依据、教育学和心理学依据等),而不是宣讲教案,也不是浓缩课堂。它的核心在于说理,在于说清为什么要这样教,用什么理论来支持教学,说课的重点在于教学重点和教学难点的突破上。说案不同于教案。     

African American family life in societal context: Crisis and hope

Since 1965 hundreds of articles and books have been published about African American families. Nevertheless, our understanding of these families continues to be limited. There is a tendency to gloss over important within-group differences; thus, monolithic, stereotypic and inaccurance portrayals of Black family life are common. This paper sets aside debates of Black family pathology or viability, focusing instead on these families' essential character. The paper seeks to understand Black families on their own terms, locating them in relevant social, historical, political and cultural contexts. Key empirical patterns and trends reveal dramatic changes in Black family geographic location, headship, quality of life and socioeconomic status since 1950.A complex picture is revealed. There has been gradual but steady overall improvement alongside persistent, extreme racial disparties and pronounced class disparities among Black families. The proposed Black Family Socio-Ecological Context model specifies and connects institutional, interpersonal, environmental, temporal and cultural facts that shape the essential character of Black family life in such a way as to produce characteristics simultaneously shared and idiosyncratic. The model also provides an organized, systematic accounting of research and public policy issues relevant to the study of African American families.An early version co-authored with Richard A. English was presented during the National Council on Family Relations Meetings in Portland, Oregon, October 1980.

A relation for the covariances of order statistics from n independent and non-identically distributed random variables

We derive a simple relation satisfied by the covariances of order statistics in the i.i.d. case and then generalize it to the case when the variables are independent and non-identically distributed. This relation could be employed successfully either to check the calculations or to reduce the amount of direct computations involved in evaluating the covariances of order statistics from an outlier model.     

Two point priors and Γ-minimax estimating in families of uniform distributions

It is shown that when a parameter lying in a sufficiently small interval is to be estimated in a family of uniform distributions, a two point prior is least favourable under squared error loss. The unique Bayes estimator with respect to this prior is minimax. The Γ-minimax estimator is derived for sets Γ of priors consisting of all priors that give fixed probabilities to two specified subintervals of the parameter space if a two point prior is least favourable in Γ.     

Estimation of critical points in the mixture inverse Gaussian model

The maximum likelihood estimation for the critical points of the failure rate and the mean residual life function are presented in the case of mixture inverse Gaussian model. Several important data sets are analyzed from this point of view. For each of the data sets, Bootstrapping is used to construct confidence intervals of the critical points.     

二维GPSJ分布类及其在保险中的应用

本文给出的二维GPSJ分布类(即GPSJ2)在保险领域应用范围较广,如由机动车辆保险由财产损失索赔次数和人身伤亡索赔次数所组成的模型、超额再保险中的由自留保单数和分出报单数所组成的二维模型等。本文在GPSJ1类基础上研究二维GPSJ类,本文给出了此分布类的定义、背景意义、概率计算的递推公式,同时还对各参数的最大似然估计值的求解过程进行了分析。本文最后将这一模型应用于一组机动车辆赔付次数数据,考虑了由财产损失索赔次数、人身伤亡索赔次数组成的二维模型,拟合效果令人满意。     

中国特色“双一流”大学建设的逻辑根据与路径选择

中国特色"双一流"大学建设有必要从学理上深入分析扎根中国大地办学的逻辑根据,从而找到有效的建设路径。为此,笔者对国外大学崛起成为世界一流大学的历史规律进行了考察,认为传承优秀民族文化是建设中国特色"双一流"大学的深层基因,回应国家战略是建设中国特色"双一流"大学的内在需求,融入民族复兴"中国梦"是建设世界一流大学的神圣使命,构建中国特色学科体系是建设"双一流"大学的强力支撑。因此,扎根中国大地建设中国特色"双一流"大学的路径选择应当是：把"立德树人"作为大学改革发展的根本任务,把传承创新民族文化作为大学改革发展的精神内核,把服务国家战略需求作为大学改革发展的根本追求,把办好人民满意的教育作为大学改革发展的自觉目标,把一流学科和一流师资建设作为大学改革发展的重要抓手。
