普通话二字组词语不同的声调组合方式 ,使前后位声调产生不同的动态变化形式。前位声调的动态变化明显表现在上声调变为低降调和中升调上 ;后位声调的动态变化则表现在调值的明显改变上。后位声调的动态变化更为普遍 ,应该引起足够的重视 相似文献

上市公司的会计造假固然有其自身利益的驱动,但也和我国目前与证券市场有关的监管制度不健全,监督体系不完善以及证券市场上的其他参与包括证券公司,会计师事所等中介机构的不规范运作有很大的关系。要解决上市公司的会计造假问题,应在完善上市公司法人治理结构的基础上,通过健全与证券市场有关的监管制度,监管体系和监管手段,强化对上市公司会计造假行为的外部约束。 相似文献

This is Part 2 of a two-part study of how APOS theory may be used to provide cognitive explanations of how students and mathematicians
might think about the concept of infinity. We discuss infinite processes, describe how the mental mechanisms of interiorization
and encapsulation can be used to conceive of an infinite process as a completed totality, explain the relationship between
infinite processes and the objects that may result from them, and apply our analyses to certain mathematical issues related
to infinity. 相似文献

With the flooding of pornographic information on the Internet, how to keep people away from that offensive information is becoming one of the most important research areas in network information security. Some applications which can block or filter such information are used. Approaches in those systems can be roughly classified into two kinds:metadata based and content based. With the development of distributed technologies, content based filtering technologies will play a more and more important role in filtering systems. Keyword matching is a content based method used widely in harmful text filtering. Experiments to evaluate the recall and precision of the method showed that the precision of the method is not satisfactory, though the recall of the method is rather high. According to the results, a new pornographic text filtering model based on reconfirming is put forward. Experiments showed that the model is practical, has less loss of recall than the single keyword matching method, and has higher precision. 相似文献

Theory Competition and the Process of Change 总被引:1,自引:0,他引:1
The reasons why many educational change initiatives have little impact are often framed in terms of either a poorly designed
process on the part of the change initiator, or in terms of problems with the attitudes, skills and/or knowledge of those
responsible for implementation. In this paper, we seek to integrate these two perspectives more closely by focusing on their
interface and the competing theories frequently held by the change initiators and implementers. This concept of theory competition
is illustrated with a case of a national literacy initiative in New Zealand in which the change initiators wished to raise
the achievement of low performing students through the development of “learning-centred” leadership in schools and evidence-based
practice. The desired outcomes were not achieved because theories about what it means to be a successful leader in such a
situation, the data needed to undertake the type of evidence-based analysis envisioned and school personnel beliefs about
the target students were understood differently by those responsible for initiating the change and those responsible for implementing
it. 相似文献
