词汇联想实验下的二语心理词汇动态分析——以某高校英语专业低年级学生为研究对象     

刘宁 《天津工程师范学院学报》2011,21(4)

以二语词汇联想实验为主要研究手段,以某高校英语专业基础阶段的两个年级学生为研究对象,探寻了中国英语学习者的二语心理词汇在不同阶段存在的异同,从而发现其发展变化特点,即：呈现出逐渐优化的趋势,反映出随着二语词汇习得量与质的提升,心理词汇意义联系逐渐加强;这也同时促进二语词汇的习得,互为作用与反作用,打破词汇僵化。  相似文献   

20世纪中国文学中的 "风水" 叙事     

陈旋波 《华侨大学学报(哲学社会科学版)》2015,(2)

近代以来, 作为中国传统文化一脉的风水观因其缺乏 "真确的知识" 而受到摒弃和批判, 五四以来风水一直受到科学理性、 唯物主义主导的文学思潮的攻伐. 随后, 20世纪中国社会及文化思潮发生了巨大的变迁,风水在文学中的境遇也因时而易, 这不但反映了时代思潮的嬗变, 还纠结着20世纪纷繁复杂的政治、 哲学及美学取向. 尤其是随着90年代中国文化语境的变迁, 风水文化逐渐浮现出其反思现代性的 "复魅" 特质.  相似文献   

旅顺博物馆藏两件高昌王麹乾固供养写经残片探析     

彭杰 《家教指南》2015,(3)

旅顺博物馆带有供养人题记的两件汉文抄经残卷,经核查考订,一件为东晋鸠摩罗什所译《仁王经》的片段,另一件为北凉昙无懺所译《金光明经》的片段。两部佛经均为佛教著名的护国经典。通过对题记部分的辨识,结合文献和其他出土文物,进一步确定了两件抄经的供养人均为麹氏高昌国的七世王麹乾固。上述两件写经残卷的发现,为新疆历史文化的研究提供了新材料。  相似文献   

汉语对云南少数民族学生第三语言(英语)习得的影响研究——以楚雄师范学院、东兴中学、紫溪中学等学校的少数民族学生为例     

李育卫 《楚雄师范学院学报》2015,(1):97-102

近年来,三语习得研究逐渐成为了语言学研究的热点之一。所谓三语习得,指的是除了学习者的母语和已经掌握的第二语言之外,目前正在学习的一种或多种语言。本文以云南省楚雄师范学院、东兴中学、紫溪中学等学校的少数民族学生为样本,对他们的第二语言(汉语)在其第三语言(英语)习得中的影响进行了研究。结果发现:(1)少数民族学生的L2(汉语)对他们的L3(英语)习得具有负迁移作用;(2)L3这种影响影响不仅停留在语音、词汇、语法和句型上,同时也会对L3习得中的听力、口语、阅读、写作及翻译产生负迁移影响:(3)有效的教学策略和学习策略将有利于减少L2对他们的L3习得的负迁移影响,并在很大程度上有利于他们的英语学习。  相似文献   

The bilateral benefits of providing and receiving peer feedback in academic writing across varying L2 proficiency     

《Studies in Educational Evaluation》2023

Although the effectiveness of peer review has been examined, few have tested the joint benefits of providing and receiving feedback features and quality in L2 contexts. The present study investigated variation in key features and quality of feedback provided and received by high and low L2 proficiency students and its benefits on revision in the authentic setting of students experiencing both roles of providing and receiving peer feedback in English academic writing. Analyses on two drafts from 50 students, 1356 idea units of anonymous implementable peer feedback and back-evaluation ratings revealed that the combined effect of providing and receiving feedback on revision was prominent for all students. But the bilateral benefits of providing and receiving feedback features were more significant for high proficiency students, while providing feedback features and quality benefited low proficiency students more. The study implies that students need more bilateral training with both providing and receiving feedback.  相似文献   

密度对车前草生长的影响     

王立凤  许丽颖  殷美娜 《黑龙江科技信息》2014,(27):254-254

以车前草为实验材料,研究不同密度(5棵/盆、8棵/盆、10棵/盆)对车前草生长状况的影响。实验表明,随着车前草密度的增大,其植株高度,叶柄高度,叶片高度也随之增加;根长,根重,叶重随着密度的增大而减小,而叶宽没有明显的变化。  相似文献

酸浆宿萼总皂苷对小鼠免疫活性的影响     

曹虎灵 《科技风》2014,(20)

本文以干燥的酸浆宿萼为实验材料,经乙醇回流提取,并通过溶剂萃取和大孔树脂进一步分离得到酸浆宿萼皂苷(TSP)。以不同剂量TPS连续20天对正常小鼠进行灌胃,探讨了TPS对小鼠免疫活性的作用。结果表明:高剂量(40mg/m L)的TPS溶液能极显著的增加小鼠的免疫器官指数(P0.05)和巨噬细胞吞噬指数;免疫球蛋白(Ig G)含量,P0.01;改善血常规指数。而低剂量(5mg/m L)的TPS溶液对小鼠上述指标有显著的正面影响,P0.05。总体上,在实验浓度范围内,TPS具有增强小鼠免疫活性的作用且呈剂量依赖性。  相似文献   

Open access to data: An ideal professed but not practised     

Patrick Andreoli-Versbach  Frank Mueller-Langer 《Research Policy》2014

Data-sharing is an essential tool for replication, validation and extension of empirical results. Using a hand-collected data set describing the data-sharing behaviour of 488 randomly selected empirical researchers, we provide evidence that most researchers in economics and management do not share their data voluntarily. We derive testable hypotheses based on the theoretical literature on information-sharing and relate data-sharing to observable characteristics of researchers. We find empirical support for the hypotheses that voluntary data-sharing significantly increases with (a) academic tenure, (b) the quality of researchers, (c) the share of published articles subject to a mandatory data-disclosure policy of journals, and (d) personal attitudes towards “open science” principles. On the basis of our empirical evidence, we discuss a set of policy recommendations.  相似文献   

Financial information management for university departments,using open-source software     

《International Journal of Information Management》2014,34(2):191-199

This paper presents a model to analyse the different outcomes generated by the application of Task-Technology Fit (TTF) theory to economic and financial information management in university departments. This model extends that proposed by Goodhue (1995), in two ways: (i) a key role is played by the manager in designing the technology and in performing the task in question. Both of these aspects can be modified, depending on the evaluation made of a series of characteristics (or dimensions) inherent to the model. (ii) The free dissemination of the source code of the application not only allows the transfer of knowledge, but also creates virtual communities which, through collaborative work and the exchange of experiences, can achieve a better fit of the technology to the task at hand. This model has been introduced in several departments at the University of Granada (Spain), and evaluated in terms of the results obtained at both individual and group levels. This evaluation was conducted by means of in-depth interviews with departmental managers.  相似文献
