This study examines the issue as to whether U.S. educational institutions need a significant change in their policy to deal with the increasing number of foreign students on U.S. campuses. Projections for the 1980s are made using Box-Jenkins and other forecasting techniques. Factors that led to the rapid growth of foreign students in the past are reviewed. The likelihood of their continuation is examined. In the light of these factors, policy implications of the projections are discussed. 相似文献

This paper discusses a mini‐experiment; an exercise was devised to investigate the effects of repeated articulation on the acquisition of syntax. The main participants of the experiment are two Hebrew‐speaking students, one formally assessed as having reading disabilities, one female age 14 (Q) and one dyslexic male age 16 (W). Q has been learning English at school for 4 years; she is in eighth grade. She is in the group for weak learners of English and does not show signs of a reading disability. She has taken private tuition once a week for approximately 5 months. She had not previously studied the target structure in the experiment. The results are discussed in light of the literature review findings, and some applied implications and conclusions were drawn for learning disabilities (LD) teaching. 相似文献

High quality summary is the target and challenge for any automatic text summarization. In this paper, we introduce a different hybrid model for automatic text summarization problem. We exploit strengths of different techniques in building our model: we use diversity-based method to filter similar sentences and select the most diverse ones, differentiate between the more important and less important features using the swarm-based method and use fuzzy logic to make the risks, uncertainty, ambiguity and imprecise values of the text features weights flexibly tolerated. The diversity-based method focuses to reduce redundancy problems and the other two techniques concentrate on the scoring mechanism of the sentences. We presented the proposed model in two forms. In the first form of the model, diversity measures dominate the behavior of the model. In the second form, the diversity constraint is no longer imposed on the model behavior. That means the diversity-based method works same as fuzzy swarm-based method. The results showed that the proposed model in the second form performs better than the first form, the swarm model, the fuzzy swarm method and the benchmark methods. Over results show that combination of diversity measures, swarm techniques and fuzzy logic can generate good summary containing the most important parts in the document. 相似文献
