援苏抗德与丘吉尔的现实主义外交

二战初期,随着希特勒向西线大举进攻,丘吉尔临危受命,出任英国首相.面对纳粹德国的威胁,他从现实的国家利益出发,积极推动英苏合作.苏德战争爆发后,丘吉尔立即发表声明支持苏联抵抗纳粹德国的侵略.援苏抗德是丘吉尔现实主义外交的代表性例证.     

交际性语言测试理论与新CET-4写作测试

交际性语言测试以测试交际能力为宗旨。具体到写作命题，它侧重命题本身的交际性。大学英语四级（CET-4）对促进大学英语教学功不可没，但其写作部分在命题、任务类型、评分标准等方面受到众多质疑。新CET-4交际性写作命题必将对写作教学产生积极的反拨作用。     

晚清与“五四”小说变革同异论

晚清与“五四”小说变革虽有动机上的相近之处,却有性质上的不同.这导致晚清小说与“五四”小说出现了形态上的差别.晚清小说变革持续的时间、规模都超过“五四”,但却没有真正实现中国小说由古典向现代的转变,主要原因在于晚清小说变革是非自觉的文学变革.相比而言,“五四”小说变革的自觉性更强,也更注重文学自身的特征.晚清小说变革并非必然走向“五四”小说,它的变革路径与“五四”有很大不同,即基本保留古典小说模式,只是在内容上和形式上容纳一些新的思想、艺术因素.“五四”小说变革因历史背景、文化语境的特殊作用,找到了一条新的路径,这就是精神与艺术的一体化即“心理化”.通过“心理化”,“五四”小说最终实现了中国小说由古典向现代的转变.

Using simulation methods for bayesian econometric models: inference,development and communication: some comments

We extend the average derivatives estimator to the case of functionally dependent regressors. We show that the proposed estimator is consistent and has a limiting normal distribution. A consistent covariance matrix estimator for the proposed estimator is provided.     

启蒙者的非启蒙心态——五四新文化运动的历史性局限

新文化运动的最大不足在于启蒙不够充分.由于历史性的诸多原因,新文化提倡者带有浓厚的科举心态,缺乏对文化启蒙及其功能的深刻理解,将启蒙当做一种政治手段,让启蒙承担起其力不能及的过分沉重的民族国家的现代性使命.这种非启蒙心态在启蒙内部构成了一种颠覆,使启蒙丧失了其本身所具有的基本价值及功能.     

The social “R & D” paradigm in child and youth services: Building knowledge convivially

Adaptation of agricultural and industrial research and development models offers new methods for bridging the worlds of research and practice in child and youth services. Social R & D methodologies provide effective means for generating new social technologies because they are product oriented and use a wide array of traditional and nontraditional data sources. This article discusses one social R & D paradigm—Developmental Research and Utilization. Permanency planning and community support systems research are used to illustrate the past and potential application of this methodology to the field of child and youth services.     

Relationships of optimality for individual factors of a design

The optimality of two-factor experimental designs is studied in the dual senses of estimating contrasts in the parameters for each of the factors. The outline of comparison employed allows one to judge the performance of different designs for estimating contrasts of one set of parameters directly with the performance of the complementary set without going through a common intermediary step of considering all the parameters. The results hold for a wide class of optimality criteria (not merely D-, A- and E-optimality), which must satisfy a functional equation obtained in connection with our method. Also we investigate the optimality of row–column designs which satisfy an ‘adjusted orthogonality’ condition. Our point of departure is the paper by Shah, Raghavarao and Khatri (1976) and that of Mitchell and John (1977).     

An infinite class of PBIB designs

In this paper, an infinite class of partially balanced incomplete block (PBIB) designs of m+1 associate classes is constructed through the use of a series of row-orthogonal matrices known as partially balanced orthogonal designs (PBOD) of m-associate classes. For the purpose, a series of PBOD is obtained through a method described herein. An infinite class of regular GD designs is also reported.
