剧本问题是阻碍中国电影发展的瓶颈

探讨在中国电影发展的百年历程中,剧本成为瓶颈的原因,认为主要是缺少优秀剧本、创作队伍不能适应新时期电影事业发展的需要、电影剧本题材范围狭小、禁忌太多、内容缺乏真实的沉淀力量、思想肤浅、缺乏令人思索的深度、热衷于自然主义的描写和急功近利的心态导致粗制滥造。等等。并针对这些问题提出了解决方法,以期有利于中国电影的健康发展。

用GC和GC／MS分析河流悬浮物上的多环芳烃

河流悬浮物上的有机污染物品种繁多，成分极为复杂，多环芳烃只是其中的一类，对这类复杂的环境样品进行分析鉴定相当困难。本文提出了一个简单而有效的预处理及预分离方法，将多环芳烃首先从复杂体系中分离出来，再采用ＧＣ／ＭＳ系统配合程序升温保留指数法，对运河苏南段的二个悬浮物样品中的多环芳烃组分进行了分析鉴定，共鉴定出多环芳烃５０余种，对检出的多环芳烃利用多重内标相对重量校正因子法进行了半定量分析。     

小说内外的蒋琬其人其事

长篇章回巨著《三国演义》中的蒋琬与史籍中的同名人物相去甚远。史籍中的蒋琬忠厚谦恭,并有治国、治军之不俗政绩;而小说中的蒋琬虽是诸葛亮选定的接班人,但表现平平。究其缘由,当由作品的题材取向与作家的情感取向所决定。因小说以历史上三国时期的军事、外交为主要描写内容,而活跃于当时政治舞台上的军事家、谋略家诸葛亮,又是作家人格理想之所在,故而诸葛亮去世之后,小说虽赋予蒋琬以治世之才、赋予姜维以治军之才,但皆逊色于诸葛;同时,作品又依循主题的需要,让身为文官的蒋琬又远不及武将身份的姜维。

Knowledge Integration in Science Teaching: Analysing Teachers' Knowledge Development

This paper tests the utility of a new sociocognitive frame for analysing the development of teachers' knowledge – the knowledge integration perspective (Linn, Eylon, & Davis, in press; Linn & Hsi, 2000). In doing so, the paper describes one prospective elementary teacher's developing knowledge and highlights its complexity. The prospective teacher demonstrates relatively well-integrated science subject matter knowledge, but she makes some problematic links to lessons and develops some instructional representations that show where she needs to distinguish between different scientific ideas. She also, however, links science concepts to appropriate real-world experiences, indicating that she has nascent useful pedagogical content knowledge. The paper discusses what teacher educators can learn about their learners from this analysis, argues for the utility of the knowledge integration perspective for conducting similar analyses, provides ideas to help science teacher educators apply the perspective easily as they teach their students, and points to areas ripe for future research.     

Second-wave white teacher identity studies: toward complexity and reflexivity in the racial conscientization of white teachers

Abstract

In this article, we introduce our special issue, ‘Second-Wave White Teacher Identity Studies: Toward Complexity and Reflexivity in the Racial Conscientization of White Teachers.’ We characterize white teacher identity studies as a developing field with important implications for education research and teacher education. Early work in this field focused on documenting, how white teachers denied and evaded the significance of race and white privilege in their work and lives. The articles in this special issue exemplify a second wave of white teacher identity studies which builds on and responds critically to this earlier work. Crucial concerns of this second-wave work include attending to the nuances and complexities of white racial identities, as well as examining the pedagogical, curricular, and institutional contexts within which these identities are taken up.
