The potential motivational values of English proverbs and quotations in Chinese EFL tea ching

Although English proverbs and quotations are quite popular with language teachers and learners, and although there are sizeable body of research addressing the various aspects of English proverbs and quotations, their potential motivational values lacks theoretical support to date. This paper intends to explore the theoretical rationales for English proverbs and quotations to be a valuable tool for inspiring teachers and textbooks in Chinese EFL teaching. Based on QIN and WEN＇s conceptual model of motivation （2002） as well as teacher-specific and group-specific motivational theories, it analyzes the potential uses of English proverbs and quotations, with the conclusion that many English proverbs and quotations may serve to be an impetus as well as affective/cognitive mediators in the pre-actional and actional stages of learning, and may help to promote teacher-specific and group-specific motivational dynamics, which in turn benefit student achievement.

Memory and Aesthetics： Study of Musical Quotations in Ives’s and Crumb’s Music

Throughout Western music history, pre-existing material has long been the aesthetic core of a new composition. Yet there has never been such an epoch as our time in which using pre-existing material, melodic quotation in particular, features so extensively in works of many of the composers. The aim of this paper is to investigate how the use of quoted tunes in a musical piece operates in an interwoven complex where time and space are of the essence. A quote is able to oscillate perpetually between one’s mental worlds of the memorable past and the imaginative present when it is highlighted enough to be recognizable from its surrounding context. Upon interpreting the use of quotation in various contexts, the aesthetic object, I argue, is the shift from original to quoted music, and vice versa. And listeners can respond aesthetically to the quotation itself even without knowledge of its provenance and textual or referential content.

Effectiveness of Context-Based Strategy for English Learning among Chinese Middle School Students

Currently,a growing number of educators are aware of the need to look for new approaches to replace the"spoon-feeding"method.Therefore,the context-based strategy began to emerge.This study aims to investigate how students derive information through contextual clues by examining the progress of Chinese middle school EFL students in terms of word recognition.The participants of this study included 20 eighth grade students from the same middle school.The participants sat for two different quizzes:a contextual vocabulary quiz(quiz A)and a direct instruction quiz(quiz B).In quiz A,the participants inferred the meaning of the target words from the example sentences,whereas in quiz B,the students utilized the accompanying English explanation to guess other new words.These students were in the experimental and control conditions,respectively.The two quizzes comprised of 15 multiple choice questions(MCQ)which differentiated the participants?word recognition response to two different learning methods.There were two significant findings from this study.First,the results showed that the context-based strategy leads to a better vocabulary learning performance compared to the direct instruction strategy.Second,although it is not as effective as the context-based strategy,the direct instruction strategy may assist EFL learners in remembering words in short term.

“语录不可阑入古文”说的生成及现代省思

唐宋以降,禅宗语录和儒家语录大行于世,流风所及,许多文士在古文写作中也自觉或不自觉地效仿语录形式,或者掺入语录中的常见用语。这种做法相当普遍,但也有不少反对的声音。迄至清代前中期,“语录不可阑入古文”成为一种集体认同。在此过程中,方苞个人思想和文学实践所起的推动作用不容忽视。这一古文观念对于端正学风、维护古文体性、推动清代古文发展起到了积极作用,但它有绝对化的倾向,因而又有其局限性。古文发展的事实证明,在合适的场合适当借鉴、采用语录形式,不仅不会伤害古文之体,相反会给古文的表达带来别样的趣味和效果。

出版传播中引号或书名号之间的顿号用法覆议

尽管GB/T 15834-2011《标点符号用法》已经实施十多年,但其中有关引号或书名号之间顿号用法的规定至今仍然争议不断,尤其是在出版传播及其相关领域的质检机制影响下,有的意见不乏激烈,背后原因及解决之道值得探究。运用文本勾连、过程构建、对比分析等方法对这一规定予以剥茧抽丝,发现其逻辑实是“省略”,其条件实为“引号或书名号标示的内容当是并列主体的全部而非部分”。对照这些内涵,相关争议论调大都难以成立,之所以争论一直存在很大程度上缘于主观态度,包括执行的态度、理解的态度、讨论的态度等,而非规定本身。端正个人态度,而后抓住实质特征,再辅以一致性原则,即可抽钉拔楔、解黏去缚。

朝鲜时代写本《传奇语录》汉语字词考探

《传奇语录》是朝鲜时代的汉文写本词典,全书共收录、训释汉语词677例,所收词条口语性鲜明。经调查,全书有俗写、异构、记音三种异文,在归类、分词、书写、训释等方面存在讹误,对这些问题进行梳理考订,可以发现全书异文与讹误的形成与汉语俗字传承、本民族语言文字影响、抄写随意以求便捷有关。本书的汉语字词,在推动域外汉字研究、相关古籍整理等方面均有价值。

基于智能体建模的新型电力系统下火电企业市场交易策略

高比例新能源渗透情景下火电企业竞价策略研究对保障火电企业运营和推进新型电力系统建设具有重要意义。基于智能体建模框架,建立电力现货市场仿真模型和机组自学习决策模型。其中,环境模块建立了考虑源荷双侧不确定性的风光火储多方参与的电力现货市场出清模型;智能体模块将火电机组投标决策过程刻画为部分观测马尔科夫决策过程,采用深度确定性策略梯度算法求解。以HRP-38节点系统为例进行仿真分析,明晰高比例新能源下火电企业市场交易策略。结果表明:在不考虑火电机组提供辅助服务的前提下,随着新能源渗透率的提高,仍有部分位置独特且具有成本优势的火电机组拥有竞争力;预测误差增大将使大容量火电机组投标策略趋于保守,而小容量机组投标策略相反;火电机组在各类场景下均具有隐性共谋倾向,即彼此隐藏信息时仍同时提高报价。

基于鲁宾斯坦讨价还价模型的跨区域河流水资源分配研究

行政区的人为分割使同一条河流流经不同的行政区域,当可分配水资源不足以满足整个区域水资源需求时,跨区域河流沿岸多利益主体因争夺稀缺的水资源就可能产生冲突。跨区域水资源分配成为解决跨区域水资源冲突问题的重要手段,鲁宾斯坦讨价还价模型凭借其能反映各利益主体讨价还价能力的特点,已在解决水资源冲突问题得到成功应用。而上述鲁宾斯坦讨价还价模型大多对各利益主体的贴现因子进行单一定值处理,忽略了贴现因子的动态变化影响。为此,在考虑贴现因子动态变化的基础上,提出了多主体鲁宾斯坦讨价还价水资源分配模型。首先,基于讨价还价轮次、需水量的偏离程度和调节系数确定了动态贴现因子,构建了考虑动态贴现因子的报价策略,并综合考虑时间成本和水量损失因素确定谈判成本;然后,构建了多主体鲁宾斯坦讨价还价水资源分配概念模型,讨论了3种因素对贴现因子的影响,开展了基于动态贴现因子与固定值贴现因子的鲁宾斯坦讨价还价模型的对比研究;最后,以大汶河流域泰安段6个行政区为例展示了模型的效果。结果表明:提出的多主体鲁宾斯坦讨价还价水资源分配模型得到的水资源分配方案能够使结束谈判轮次提前,降低谈判成本,较好的均衡了各利益主体之间的经济社会发展水平,为得到各利益主体均能接受的合理分水方案提供了新方法,拓展了跨区域水资源分配理论。

面向深度行情因子挖掘的分布式训练关键技术研究

深度行情数据是沪深交易所的新一代实时行情数据产品,是普通基础行情数据的升级版,是目前国内信息密度最高、蕴含信息量最大、挖掘最不充分的行情数据,对挖掘证券市场潜在风险具有重要价值。但是,现有研究缺少基于深度行情数据面向证券市场的风险度量和计算分析,且全市场深度行情数据规模大,用于提取信息的深度学习模型也越来越复杂,尽管当下硬件的计算能力也在一直不断地发展与提高,但仍然无法解决训练耗时长、效率低等问题。因此,基于沪深300成分股深度行情数据,利用深度学习等方法挖掘高频波动率因子,构建了基于TabNet与LightGBM的高频波动率预测模型。同时,提出了一种基于并行差分进化的分布式训练算法Parallel_DE,用于模型分布式训练过程中的参数计算,并详细阐述了其场景映射方案与整体流程设计。针对上述2项工作基于自有分布式训练平台进行充分验证,实验结果表明,高频波动率预测模型可以对已实现波动率进行高精度预测,且效果相较于其他方法具有一定优越性;Parallel_DE算法可以在一定程度保留参数多样性的同时,有效减少本地参数在测试集上的误差,从而高效率分布式地训练出性能优良的深度学习模型,为证券市场的风险识别提供了面向深度行情数据的相关技术与方法。

A highly reliable encoding and decoding communication framework based on semantic information

Increasing research has focused on semantic communication,the goal of which is to convey accurately the meaning instead of transmitting symbols from the sender to the receiver.In this paper,we design a novel encoding and decoding semantic communication framework,which adopts the semantic information and the contextual correlations between items to optimize the performance of a communication system over various channels.On the sender side,the average semantic loss caused by the wrong detection is defined,and a semantic source encoding strategy is developed to minimize the average semantic loss.To further improve communication reliability,a decoding strategy that utilizes the semantic and the context information to recover messages is proposed in the receiver.Extensive simulation results validate the superior performance of our strategies over state-of-the-art semantic coding and decoding policies on different communication channels.

An Expert System to Detect Political Arabic Articles Orientation Using CatBoost Classifier Boosted by Multi-Level Features

The number of blogs and other forms of opinionated online content has increased dramatically in recent years.Many fields,including academia and national security,place an emphasis on automated political article orientation detection.Political articles(especially in the Arab world)are different from other articles due to their subjectivity,in which the author’s beliefs and political affiliation might have a significant influence on a political article.With categories representing the main political ideologies,this problem may be thought of as a subset of the text categorization(classification).In general,the performance of machine learning models for text classification is sensitive to hyperparameter settings.Furthermore,the feature vector used to represent a document must capture,to some extent,the complex semantics of natural language.To this end,this paper presents an intelligent system to detect political Arabic article orientation that adapts the categorical boosting(CatBoost)method combined with a multi-level feature concept.Extracting features at multiple levels can enhance the model’s ability to discriminate between different classes or patterns.Each level may capture different aspects of the input data,contributing to a more comprehensive representation.CatBoost,a robust and efficient gradient-boosting algorithm,is utilized to effectively learn and predict the complex relationships between these features and the political orientation labels associated with the articles.A dataset of political Arabic texts collected from diverse sources,including postings and articles,is used to assess the suggested technique.Conservative,reform,and revolutionary are the three subcategories of these opinions.The results of this study demonstrate that compared to other frequently used machine learning models for text classification,the CatBoost method using multi-level features performs better with an accuracy of 98.14%.

何以载道:理学语录在宋代的话语论争及意义建构

作为承载理学思想的重要著述形式,语录时常被认为是异于注疏和文章的,能延续讲学精神、发挥面谈口授优势的文本,然而这一认识与宋代理学家的意见不尽相合。语录乃介于口传与书传之间的特殊形态,其口传的优势不能掩盖它在书传方面的弊端。因记录者介入而导致的文本失真、失控,以及编纂和运用过程中对无功利、重体会的理学精神的背离,使语录遭到程颐、谢良佐等人的批评。批评者表面上否定了语录,但实际上起到了规训语录的记载和阅读行为,使其回归格物致知正轨的作用。语录与文章均属载道之具,本无优劣之分。二者的对立乃理学日常化理念所引发,“作文害道”与“语录非文”的话语争锋印证了它们在不同空间的局限与活力。

论库尔塔格三部作品的“引用”现象——基于德勒兹“块茎”理论分析与阐释

当代匈牙利著名作曲家库尔塔格的音乐创作中存在一种独特的“引用”现象,可理解为库氏本人惯用的音乐创作手法。从形式上看,这种“引用”汇集了借用、拼贴、现成品挪用等一系列音乐创作手法,但其实质却隐含诸多与作曲家创作思维及理念休戚相关的复杂问题。库氏音乐创作中的“引用”现象在其室内乐作品中得到了充分体现,并得到法国哲学家吉尔·德勒兹的“块茎”理论对其分析与阐释。

审计师跨层次执业与审计意见决策——基于我国多层次资本市场的证据

基于我国多层次资本市场的差异化制度场景,探讨审计师于同一年度在多个层次资本市场的执业行为(即跨层次执业)对其在新三板市场审计意见决策的影响。基于2014—2019年间新三板公司的数据,研究发现:跨层次执业的审计师为新三板客户出具非标准审计意见的概率显著低于新三板市场其他企业;机制检验表明,跨层次执业主要通过抑制审计师的投入,即降低执业效率、阻碍信息沟通、缩减行业知识投入,进而对审计意见决策产生负面影响。进一步从“事务所-审计师”资源配置及其他经济后果等视角开展分析,丰富了个体审计师决策形成机制的相关文献,也从制度优化角度为未来的资本市场统一审计监管提供了参考。

谢灵运赋引《诗》——兼论南朝赋引《诗》之嬗变

谢灵运赋作引用先秦典籍现象层出不穷,其中引用《诗》达48次之多,展现出晋宋之际赋家以《诗》代言、引《诗》取辞的一面。其赋引《诗》突破了先秦引《诗》说理、汉赋引《诗》的政治传统,注重《诗》的史学、文学价值。谢赋引《诗》取辞追求陌生化、独创性的表达,开南朝求新求奇风气之先河;引《诗》与引其他家经典并置而观,体现了从尊儒经转变为尊多家经典的观念变化;引《诗》事不取实指而取普遍意义,有时甚至为了贴合文本语境,赋家会消解部分诗义。这一系列行为都体现了南朝文人引《诗》“尊经”与“通变”的新变化。

混合相似性度量的仪表询价电子表格结构识别

对仪表企业来说,快速高效地自动响应用户的询价请求,实现无人化询价,具有非常重要的意义。但不同用户提供的物料清单表无统一规范的格式,导致仪表企业只能获得半结构化的询价电子表格,无人化询价系统难以分析与理解。构建无人化询价系统的关键是准确地自动提取仪表参数,而提取参数的前提是正确理解表格结构。因此,以构建无人化询价系统为目标,研究仪表询价电子表格的结构识别,提出混合相似性度量表格结构识别方法(hybrid similarity metrics for table structure recognition, HSMTSR)。所提方法结合Levenshtein距离、Dice系数和单元格类型相似度(cell type similarity, TySim),根据单元格和行数据的相似度解析识别表格结构。同时,建立流量仪表电子表格数据集(flowmeter spreadsheet dataset, FSDS)研究分析仪表询价电子表格的结构,包括714个电子表格,8 574行数据。实际应用表明,所提方法可准确高效地自动识别多种复杂结构的仪表询价电子表格,并在多个评价指标上均取得较好效果。
