李贺  杜杏叶 《图书情报工作》2020,64(1):93-104

[目的/意义] 创新性是对学术论文质量最基本的要求，是学术论文的灵魂，是学术论文评价的核心。知识元是学术论文基本组成单元。基于知识元理论和机器学习相关理论与算法，从学术论文内容层面研究计算机如何智能化地进行创新性评价及其实现过程与方法。[方法/过程] 首先，构建学术论文的研究问题、理论、方法、结论4个知识元本体，接着提出基于知识元的学术论文创新性判断模型。其次，根据学术论文研究特点，构建理论与方法机器分类模型及知识元的抽取规则与抽取方法，建立规则库和知识语料库。最后，基于语义相似度计算方法，根据判断规则和相关权重对学术论文4个维度的创新性进行评分。[结果/结论] 基于知识元抽取的学术论文创新性评分系统的实证结果表明，该智能化评价方法具有一定的可行性，可为学术论文内容创新性智能化评价系统的最终实现提供方法借鉴。  相似文献   

PCSI:一种单篇论文被引频次标准化方法     

伍军红  肖宏  任美亚  冯士雍  丁哲 《图书情报工作》2020,64(23):22-30

[目的/意义] 文章的被引频次一直是量化评价一篇论文学术影响力的重要指标。但在不同学科不同年份发表的论文会因该领域研究论文数、引用滞后等因素呈现较大的差异。因此在对比两篇论文时，难以简单依据被引频次的绝对值来评判论文影响力大小。为此，本文设计了一个新的可计算数学模型，使得每篇论文可以有一个标准化的指标，以便对不同学科不同年份发表的论文的学术影响力进行直接比较。[方法/过程] 通过分析2006、2017两年中国科技类学术期刊各学科论文的被引频次分布规律，采用同学科论文被引频次的分布形态最接近对数正态分布的先设条件，提出一种被引频次标准化指数——Paper Citation Standardized Index （简称PCSI，中文"论文引证标准化指数"）。最后以中国科协优秀科技期刊论文评选结果为例，将它们与论文所属学科全部论文进行实证对比研究。[结果/结论] 结果证明，PCSI对不同年份、不同学科论文的被引频次进行了标准化，反映了被引频次的线性差距，是一种较为理想的单篇论文学术影响力比较评价工具。  相似文献   

成果与局限:试论我国首次体育学术论争     

李凤梅 《武汉体育学院学报》2020,54(11):34-40

新中国成立初期体育学界的探索和体育事业的发展，为当代体育哲学社会科学发展提供了重要的经验启示和思想资源。出于复杂原因，当时被"双百"方针孕育而生的首次体育学术论争，鲜有人提及。在学界内外争鸣氛围的激励下，这次论争系统总结了当时体育发展中的基本问题，空前活跃了体育研究氛围，也促使篮球战术、体育内行与外行、武术渊源和发展等具体问题的讨论得以深入展开；而历史条件的特殊性和局限性，致使其偏离了体育场域且未能充分关注基本国情；从研究者的态度、论争者的遗憾和体育界的反思等层面，对我国首次体育学术论争及其深远影响进行研判。  相似文献   

高校图书馆科普基地社会化服务探索——以西华师范大学图书馆为例     

魏海霞  吴晓川 《图书情报工作》2019,63(18):47-53

[目的/意义]针对我国高校图书馆社会化服务效果不佳的状况，试图寻找一种有效且能长期开展的模式，以促进高校图书馆广泛参与，更好地满足民众的文化需求。[方法/过程]以西华师范大学图书馆为例，从组织构建、运作模式、社会效益概述科普基地社会化服务模式，并分析该模式具有构建约束机制、资源保障机制与激励机制、服务渠道的畅通机制的优势。[结果/结论]在自愿的原则下，高校图书馆与省委宣传部、省社科联联合共建科普基地以开展社会化服务，通过经费多家出，协调搭台，借用科普基地完善的管理体制与运行机制，构建高校图书馆社会化服务的长效机制。科普基地工作已在全国广泛开展，高校图书馆作为重要的文化服务单位位于申报对象之列且容易具备申报条件。因此，科普基地社会化服务模式是一种灵活的、有效的、可操作的，且具有广泛参与机制与可持续的模式，值得推广。  相似文献   

臧庸与扬州学派学术交游考     

沈明杰 《扬州教育学院学报》2020,(1):29-33

臧庸学术境界的提升和他与扬州学派名家的学术交游有着密切关系。其中,臧庸多次受刘台拱关照与举荐,并请为撰序;王念孙、王引之父子曾托臧庸校《小学钩沉》一书;臧庸视焦循为“谈天三友”之一,且为之撰写《焦氏世徳记》;阮元多番邀臧庸校《经籍籑诂》《十三经注疏》等书;凌廷堪以《校礼堂文稿》示臧庸,并属题《校礼图》。关注臧庸与扬州学派的学术交流,对探讨臧庸的学术成就以及扬州学派和常州学者的学术联系有着重要意义。  相似文献   

Ebooks in Academic Libraries     

Brad Vogus 《Public Services Quarterly》2020,16(3):182-185

Abstract

The number of ebooks continues to grow in academic libraries. Ebooks have many advantages that make them attractive as a library resource. However, ebooks also have restrictions. These include use and sharing restrictions, license restrictions, and technological barriers. Some students also prefer print books for specific tasks. The following articles examine many aspects of ebooks in academic libraries, including student preference, overall ebook use, and the advantages and disadvantages of various ebook acquisition models.  相似文献   

Adaptation and evaluation of a learning analytics dashboard to improve academic support at three Latin American universities     

Julio Guerra  Margarita Ortiz-Rojas  Miguel Angel Zúñiga-Prieto  Eliana Scheihing  Alberto Jiménez  Tom Broos  Tinne De Laet  Katrien Verbert 《British journal of educational technology : journal of the Council for Educational Technology》2020,51(4):973-1001

Despite the success of academic advising dashboards in several higher educational institutions (HEI), these dashboards are still under-explored in Latin American HEI's. To close this gap, three different Latin American universities adapted an existing advising dashboard, originally deployed at the KU Leuven to their own context. In all three cases, the context was the main ruling factor to these adaptations. In this paper, we describe these adaptions using a framework that focuses on four different elements of the context: Objectives, Stakeholders, Key moment and Interactions. Evaluation of the adapted dashboards in the three different Latin American universities is conducted through pilots. This evaluation shows the value of the dashboard approach in different contexts in terms of satisfaction, usefulness and impact in academic decision-making and advising tasks. The main contribution of this paper is the systematic reporting of the adaptations to an academic advising dashboard and showing the value of an academic advising dashboard on academic decision-making and advising tasks.  相似文献   

The effect of number of siblings and birth order on educational attainment: Empirical Evidence from Chinese General Social Survey     

《International Journal of Educational Development》2020

Data from China demonstrate that the effect of the number of siblings on education is restricted by many factors, such as children’s gender, urban or rural household registration, whether there is only one child, the birth order of children within the family, and parents’ status. Chinese families have significant preferences for the eldest son and the youngest son. Moreover, research based on the natural experiment and instrumental variable approach suggests that market-oriented reform of education has increased the cost of family education expenditures since China’s reform and opening up, which further aggravates the negative impact on education of having many siblings in an urban setting.  相似文献   

Do children spend too much time in schools? Evidence from a longer school year in Indonesia     

《Economics of Education Review》2014

I examine the effects of a longer school year in Indonesia on grade repetition, educational attainment, employability, and earnings. I exploit an arbitrary rule that assigned students to a longer school year in Indonesia in 1978–1979, which fits a fuzzy regression discontinuity design. I find the longer school year decreases the probability of grade repetition and increases educational attainment; it also increases the probability of working in formal sectors and wages later in life. These results suggest the length of school years in Indonesia is not too long.  相似文献   

The kid's speech: The effect of stuttering on human capital acquisition     

《Economics of Education Review》2014

A number of studies have shown that childhood speech disorders such as stuttering are associated with lower test scores and educational attainment. However, it is unclear whether these associations are causal in nature or whether they can be explained by difficult-to-measure heterogeneity at the community, family, or individual level. Using data from the National Longitudinal Study of Adolescent Health and ordinary least squares, we show that stuttering is negatively associated with high school grades, the probability of high school graduation, and the probability of college attendance. However, empirical specifications with family fixed effects or controls for learning disabilities such as Attention Deficit Hyperactivity Disorder suggest that these associations can, in large part, be explained by difficult-to-measure heterogeneity.  相似文献
