形态与意蕴的对应图式——陶然散文文体实验浅析

陶然近三年的散文创作充分表现了他文体意识的自觉。他高频度、高密度地把意识流引进了散文创作领域。这不仅是作家创造力的再一次释放 ,也是多元共生的散文创作方法探索的一个新向度。这种探索的直接效果是文本的外在形态的快节奏、跳跃和不连贯。这又是与作家面对困惑时的不安、焦灼的内在世界相契合的。因此 ,陶然在形式上的探索并不是孤立的、为形式而形式的。他建构了一个散文文本外在形状与内在意蕴互为表征的对应图式     

Making the Hidden Explicit: Learning About Equity in K-8 Preservice Science Education

Preservice teachers in a K–8 science methods course used guided video reflection to examine their interactions with children during science teaching. This inquiry approach helped preservice teachers identify and respond to gaps between their beliefs and intentions about teaching all children and their enactment of those beliefs. The experience of teaching a science lesson and then viewing it multiple times through a critical framework provided an opportunity for preservice teachers to recognize hidden assumptions, unexamined behaviors, and the unintentional meanings they may have conveyed to children. This encouraged them to think more critically about their roles as teachers in creating spaces where all children have access to quality science learning experiences.

An appraisal of techniques and equipment for cutting force measurement

INTRODUCTION Metal machining processes are characterised mainly by quick changes in quantified elements. In- dividual changes do not occur in isolation and they influence each other. The analysis of these changes require study of the complicated complete systems in their real situations. The study of cutting processes such as turning and facing, from dynamic aspects, is very important. The trend towards the measurement of cutting forces in machining leads to many theo- retical and practic…     

微机控制自动变频恒压供水技术之我见

在燥矿生产过程中,各个环节都会产生大量的矿尘,而矿尘能否有效控制直接关系到矿井的安全生产和职工的身体健康,《煤矿安全规程》规定矿井必须建立完善的防尘供水系统。随着矿井综合机械化程度的提高,对矿井防尘供水压力的要求也不断提高,《规程》规定采煤机内、外喷雾压力不得小于2MPa,掘进机内、外喷雾压力不得小于3MPa。对于煤层埋藏较浅,综合机械化程度较高的矿井,靠传统的静压供水防尘系统已不能满足矿井生产的需要。随着微机控制、变频技术的不断发展,采用当代先进的微机控制技术和变频技术解决综合机械化矿井目前防尘供水系统压力不足、流量不稳定的问题,已成为势在必行的趋势。     

Internet Fantasy Violence: A Test of Aggression in an Online Game

Research on violent video games suggests that play leads to aggressive behavior. A longitudinal study of an online violent video game with a control group tested for changes in aggressive cognitions and behaviors. The findings did not support the assertion that a violent game will cause substantial increases in real-world aggression. The findings are presented and discussed, along with their implications for research and policy.
