民国档案文件级目录著录是国家重点档案保护与开发项目的重点内容,其在著录过程中存在明显的难点,加之著录人员自身的局限性,造成了著录错情远远超过国家重点档案文件级目录采集标准的要求。本文以福建省档案馆为例,通过对著录错情的类型分析、原因剖析,探讨提高民国档案文件级目录著录质量的有效对策。  相似文献

大学生英语写作中的句法错误主要是由于英汉思维差异导致的。语言相对论,又称"萨丕尔-沃尔夫假说",是探究语言和思维、文化之间关系的重要理论。本文从"语言相对论"角度,分析了中西思维方式及其差异导致的大学生英语写作中常见的句法错误,并从文化角度提出相应的对策,以期为大学英语教学理论和实践研究提供一些启示。  相似文献

Abstract

Academics have a responsibility to ensure that their research findings are as truthful as possible. InIn every issue of a scientific journal, a large number of significance tests are reported (usually using P <0.05). Of course, most of these results will be true/correct. Unfortunately, due to the nature of sampling, researchers will occasionally make errors, often referred to as type I (probability = α) and type II (probability = β) errors. The power of a test (1-β) is the probability of correctly rejecting a false null hypothesis – that is, correctly detecting a real or true effect. Factors that are known to influence power include: (1) the level of significance (α), (2) the size of the difference or relationship in the population (the effect), (3) the sample size, and (4) unexplained error variance. As researchers, we have little control over most of these factors. The one factor that we have some influence over, however, is the ability to reduce the unexplained error variance. In the present article, we describe a range of methods that will increase the probability that a researcher has correctly identified a real effect by increasing the power of their statistical tests. Such methods will include ways of designing experiments to reduce error and uncertainty. The use of blocking and randomized block designs will reduce unexplained error, such as adopting matched or repeated-measures designs rather than using independent observations. The other method of reducing unexplained errors is to adopt more appropriate (e.g. biologically correct) models and checking the distribution assumptions associated with such models. In conclusion, researchers are responsible for maximizing the likelihood that their results are as accurate and truthful as possible. By carefully planning their experiments and adopting appropriate models, researchers are more likely to publish their findings with a greater degree of confidence, but not certainty.  相似文献

郭象《庄子注》,据《晋书》本传记载,系窃取向秀庄子解义而为之。向秀“解义”早已不存,郭象究竟窃取向秀作的那些内容,这一桩公案现在已很难弄得清楚。因而,这篇专挑毛病的章,就把挑出来的错都记在郭象账上。谁教他偷书,而且历史也无可奈何地承认《庄子注》是郭象的作,并公认为最能阐释庄子思想的作品呢!  相似文献

泰国留学生在书面语里出现的偏误现象分为以下几个类型:复句的逻辑性偏误、程度副词偏误、遗漏偏误、增补偏误、语法规则偏误等。外国学习者所产生的偏误大体上都是基于“五个中心过程”理论而形成的。偏误的产生是正常的,偏误分析的作用就在于针对汉语自身的特点分析、归纳、总结习得者的习得规律,从而提高对外汉语的教学效果。  相似文献

Errors are often perceived by students as self-threatening and not as learning opportunities. The present work focuses on contextual influences on reactions to errors and learning processes. Based on prior research, a conceptualization of perceived error climate in the classroom with eight subdimensions and one superordinate uniform factor is proposed and a newly developed student questionnaire for its assessment is presented. Results of a study with N = 1116 students from 56 mathematics classrooms in German secondary schools indicated the validity of the error climate conceptualization and the suitability of the questionnaire. Moreover, the results showed that perceived error climate in the classroom predicted the adaptivity of students’ individual reactions to errors above and beyond perceived classroom goal structures and personal achievement motivation (academic self-concept, mastery goal orientation). In addition, the study provided evidence that perceived error climate affects – partially mediated through students’ individual reactions to errors – the quantity and self-regulation of students’ effort.  相似文献
