大战略是指国家联盟、国家或政治集团运用以军事为主的综合手段达成政治目标的总战略。《孙子兵法》中所说的“庙算”、秦汉以来所流行的“大略”等概念含义与之相近。《孙子兵法》中的大战略思想主要包括“察”战、备战和慎战的重战战略思想、以“伐谋”、“伐交”为主的“不战”战略思想和唯“战道”是从的“善战”战略思想三部分内容。这三者是一个密切关联的有机整体。 相似文献

地方官是促进区域社会农业科技交流推广的必要中介。清代四川相当一部分外省籍地方官对辖区农业着力经营,不失时机地引进、推广新的作物品种,使农业技术更趋精细化,并推动农业科技改良组织的建立与农业科技著作的编撰、刊印和流布。四川一些农业科技也藉地方官之力传播到省外。地方官通过科技交流推广以发展农业文明的历史传统,当进一步总结发扬。 相似文献

Exploring the fluctuation of motivation and use of self-regulatory processes during learning with hypermedia 总被引:1,自引:0,他引:1
We collected think-aloud, pre-test, post-test, and motivation data from 43 undergraduates to examine the impact of conceptual
scaffolds on the fluctuation of certain motivation constructs and use of self-regulatory processes during learning with hypermedia.
Participants were randomly assigned to either the No Scaffolding (NS) or Conceptual Scaffolding (CS) condition. During the
experimental session, each participant individually completed a pre-test on the circulatory system, a pre-task motivation
questionnaire, one 30-min hypermedia learning task during which they learned about the circulatory system, a motivation questionnaire
at three regular intervals during this learning task, a post-test on the circulatory system, and a post-task motivation questionnaire.
Results indicated that while participants in both conditions gained declarative knowledge, participants who received conceptual
scaffolds during learning demonstrated deeper understanding of the circulatory system on the post-test. In terms of self-regulatory
processes, the results indicated that participants in the CS condition used significantly more planning processes during learning
than participants in the NS condition. Additionally, participants in both conditions significantly decreased their use of
strategies as they progressed through the learning task. Regarding motivation while learning with hypermedia, results indicated
that participants in both conditions reported significantly increased levels of interest as they progressed through the learning
task. Furthermore, participants in the CS condition reported the task as being easier and putting forth less effort than participants
in the NS condition.

The history of curriculum debate involving science in the United States has touched all levels and concepts of schooling. It has involved a wide spectrum of competing interests and ideas. It has helped guide the framing of concepts as complex and influential as those of progress, human nature, and the national welfare. It has been a stage on which many players have entered, spoken, left, and returned (not always in the guise of farce). Above all, it is itself something from which a great deal can be learned: for in large part any current situation stands at the apex of this long history and cannot in any sense be divorced from what it reveals about the larger place of science and learning in American consciousness. Eric Hobsbawm once wrote that the progress of schools and universities measures that of nationalism, and that education generally is the most conscious champion of the state. History reveals this to be an enormous oversimplification, woefully expedient, and particularly so in the case of science. Here, in fact, nationalism itself can be revealed as a collision of many conflicting interests, myths, visions, and hopes, all of which at some point took the scientific as legitimating dais. No committed history could be so reductive. It must rather open both inward and outward, toward the past and its continued momentum. 相似文献

It shows in the tendency of the global economic development in recent years that Services Science would no doubt become the next hot topic in economic study. And service supply chain is a new study aspect in supply chain management of services science. This article begins with study on the definition and characters of service supply chain, compares this with traditional supply chain,establishes the structure of its form and puts it into our regional economics to examine its impacts. 相似文献
