Analytic Atomic Screening Parameters for Slater Type Orbitals

Screening parameters to be used in Slater Type Orbitals were obtained in analytic form. The values compared well with the numerical results given by Clementi and Roetti (after a laborious process of optimization) and with the phenomenological values of Jung and Gould. The analytic formulation is based on the splitting of the two-body operator 1/r_st as the sum of effective one-body operators.

Dynamic models of segregation†

Some segregation results from the practices of organizations, some from specialized communication systems, some from correlation with a variable that is non‐random; and some results from the interplay of individual choices. This is an abstract study of the interactive dynamics of discriminatory individual choices. One model is a simulation in which individual members of two recognizable groups distribute themselves in neighborhoods defined by reference to their own locations. A second model is analytic and deals with compartmented space. A final section applies the analytics to ‘neighborhood tipping.’ The systemic effects are found to be overwhelming: there is no simple correspondence of individual incentive to collective results. Exaggerated separation and patterning result from the dynamics of movement. Inferences about individual motives can usually not be drawn from aggregate patterns. Some unexpected phenomena, like density and vacancy, are generated. A general theory of ‘tipping’ begins to emerge.     

和而不同:英语中的中国因素

中国从19世纪初到现在接触和使用英语已有近两百年的历史,由于中西文化的相互影响和渗透,许多汉语的词汇逐渐进入英语,成为英语的一部分。中国英语以英国英语为核心,但有着鲜明的中国特色。本文拟从语言变异:中国因素的融入根源、顺应理论:验证中国因素的表现特色、英语全球化、本土化:引导中国因素的发展趋势三个方面阐释英语中的中国因素。     

对许渊冲《江城子·记梦》英译本的鉴赏及其辨析

许氏翻译理论虽在学界见仁见智，但却毫无疑问地已构成具有中国特色的中国学派的文学翻译理论的重要组成部分。在鉴赏解读许氏翻译理论的基础上，以许渊冲先生“三美”“三化”“去粗存精”及再创论和优化论等翻译理论为指导，对其《江城子＆#183;记梦》的英译本进行鉴赏和辨析。与此同时，结合诗词翻译的特殊性，就其“粗”与“精”的判断标准是否具有普适性、有时难免为了追求押韵而因韵害意及过度“深化”的问题，即对翻译的技术处理的细节问题进行辨析，并提出改良译法的意见。     

后实证主义的兴起对心理学理论建设的意义

后实证主义的兴起对实证主义统治下的心理学危局有一定的挽救意义,它超越了传统的二元论视野,扶正了理论建设在心理学中的地位,为心理学提供了元理论基础和新的评价标准。     

Dynamics of the rotational degrees of freedom in an undercooled crystal of cyanoadamantane

Results of molecular dynamics are presented for a simple model of cyanoadamantane crystal. Rotator cubic phase was simulated over a wide range of temperatures. In this system, glass formation is not induced by quenched diluted disorder, but it occurs similarly to conventional glasses. Simulations have shown that the system evolves from free small-step rotational diffusion to jump like motion. The results obtained with this model are used to discuss the validity of the Mode Coupling Theory (MCT) predictions.
