试论英汉动物习语的文化差异 总被引:1,自引:0,他引:1
杜素霞 《漯河职业技术学院学报》2010,9(3):87-89
语言和文化是密不可分的,英汉动物习语的差异也反映了中西文化的差异。通过英汉动物习语文化内涵的对比分析,我们可以清楚地看到:任何一种语言中的动物习语都不仅仅是动物形象的符号代表,文化差异给动物习语打上了深深的文化印记,动物习语也因此具有丰富的文化内涵。 相似文献

随着两栖动物新种、新属和国内新纪录等陆续发表,导致梵净山两栖动物分类地位陈旧,有许多与当前分类标准不符,给梵净山两栖动物以后的研究带来不便.本文对其分类地位修改进行专门总结,发现与以前相比,梵净山两栖动物科、种数量未变,但一些目、属、种名和原隶于蛙属的种及原隶于锄足蟾科的属分类有改动,同时增加了4亚目、5亚科和5属的分类阶元。这样梵净山拥有两栖动物就由原2目(1亚目)8科11属34种变为2目(5亚目)8科(5亚科)16属34种. 相似文献

This study examined students alternative conceptions of reptiles and amphibians and the extent to which these conceptions remain intact through the elementary (grades 4 and 6), junior, and senior high school years. We administered multiple-choice and free-response instruments to a total of 513 students and interviewed at least 20 students at each educational level to get an in-depth view of their original conceptions. Then, we developed and administered a two-tier multiple choice diagnostic instrumentto assess various levels of students understanding of amphibians and reptiles(N=1267). The results showed that most students were able to classify snakes as reptiles, whereas fewer than 30% of the students across different ages classified sea turtles as reptiles; the remaining 70% classified sea turtles as amphibians. More students were able to correctly classify frogs as amphibians than toads. In most instances, students correctly classified prototypical representatives of the two animal classes more readily than less exemplary representatives, a finding that supports previous research (Trowbridge, J.E. andMintzes, J.J. (1988). Alternative conceptions in animal classification: A cross-age study. Journal of Research in Science Teaching, 25(7), 547–571). Interestingly, the alternative views of sea turtles as amphibians remained intact throughout the school years. Interview data indicated that students classified sea turtles as amphibians largely because sea turtles are able to live in terrestrial and aquatic habitats. Semantically, amphi means living on land and in water. When asked to distinguish between reptiles and amphibians and to classify several species into those two groups, a wide range of alternative conceptions emerged and the origin of those alternative conceptions are discussed. Similar results were obtained when we applied a two-tier multiple-choice diagnostic instrument to assess students understanding of amphibians and reptiles. 相似文献

问句分类作为农业智能问答系统的核心模块之一,对问答系统的检索效率有决定性影响。针对农业问句特征稀疏、描述不规范等问题,基于深度预训练方法BERT或ERNIE构建农业问句分类模型。在农作物、园艺、养殖技术、水产渔业、农业工程5个类别下设计3组实验,使用12.5万条农业数据集进行实验验证,并与典型深度学习方法TextRNN-Attention、Transformer进行比较,同时考察增加数据集对分类结果的影响。实验结果表明,基于深度预训练语言模型的农业问句分类效果最好,其中ERNIE模型在测试集上的F1值最高可达94.76%,比其他模型的精确率、召回率和F1值提升1%~3%。此外,在增加数据集的情况下各模型的F1值均有所提升。深度预训练模型ERNIE可对农户的提问进行自动分类,具有更优的农业问句文本分类效果。 相似文献

When scores are used to make decisions about respondents, it is of interest to estimate classification accuracy (CA), the probability of making a correct decision, and classification consistency (CC), the probability of making the same decision across two parallel administrations of the measure. Model-based estimates of CA and CC computed from the linear factor model have been recently proposed, but parameter uncertainty of the CA and CC indices has not been investigated. This article demonstrates how to estimate percentile bootstrap confidence intervals and Bayesian credible intervals for CA and CC indices, which have the added benefit of incorporating the sampling variability of the parameters of the linear factor model to summary intervals. Results from a small simulation study suggest that percentile bootstrap confidence intervals have appropriate confidence interval coverage, although displaying a small negative bias. However, Bayesian credible intervals with diffused priors have poor interval coverage, but their coverage improves once empirical, weakly informative priors are used. The procedures are illustrated by estimating CA and CC indices from a measure used to identify individuals low on mindfulness for a hypothetical intervention, and R code is provided to facilitate the implementation of the procedures. 相似文献

论学校发展性心理辅导 总被引:10,自引:0,他引:10
近年来,发展性心理辅导日益受到广大学校心理健康教育工作者的重视,并以其“预防性”和“发展性”逐渐成为学校心理健康教育工作的发展方向。发展性心理辅导是在心理科学理论不断发展的背景下,以心理健康标准的重新界说为契机而发展起来的,体现了学校心理辅导发展趋势的一种理论模式。该模式以全体学生为辅导对象,注重学生心理潜能的开发和人格的完善。学校发展性心理辅导的实施可以采取班级心理辅导活动课、个别或团体咨询、家庭和社区辅导网络相结合的金三角模式。 相似文献

Performance assessments, scenario‐based tasks, and other groups of items carry a risk of violating the local item independence assumption made by unidimensional item response theory (IRT) models. Previous studies have identified negative impacts of ignoring such violations, most notably inflated reliability estimates. Still, the influence of this violation on examinee ability estimates has been comparatively neglected. It is known that such item dependencies cause low‐ability examinees to have their scores overestimated and high‐ability examinees' scores underestimated. However, the impact of these biases on examinee classification decisions has been little examined. In addition, because the influence of these dependencies varies along the underlying ability continuum, whether or not the location of the cut‐point is important in regard to correct classifications remains unanswered. This simulation study demonstrates that the strength of item dependencies and the location of an examination systems’ cut‐points both influence the accuracy (i.e., the sensitivity and specificity) of examinee classifications. Practical implications of these results are discussed in terms of false positive and false negative classifications of test takers. 相似文献
