Topic evolution has been described by many approaches from a macro level to a detail level, by extracting topic dynamics from text in literature and other media types. However, why the evolution happens is less studied. In this paper, we focus on whether and how the keyword semantics can invoke or affect the topic evolution. We assume that the semantic relatedness among the keywords can affect topic popularity during literature surveying and citing process, thus invoking evolution. However, the assumption is needed to be confirmed in an approach that fully considers the semantic interactions among topics. Traditional topic evolution analyses in scientometric domains cannot provide such support because of using limited semantic meanings. To address this problem, we apply the Google Word2Vec, a deep learning language model, to enhance the keywords with more complete semantic information. We further develop the semantic space as an urban geographic space. We analyze the topic evolution geographically using the measures of spatial autocorrelation, as if keywords are the changing lands in an evolving city. The keyword citations (keyword citation counts one when the paper containing this keyword obtains a citation) are used as an indicator of keyword popularity. Using the bibliographical datasets of the geographical natural hazard field, experimental results demonstrate that in some local areas, the popularity of keywords is affecting that of the surrounding keywords. However, there are no significant impacts on the evolution of all keywords. The spatial autocorrelation analysis identifies the interaction patterns (including High-High leading, High-Low suppressing) among the keywords in local areas. This approach can be regarded as an analyzing framework borrowed from geospatial modeling. Moreover, the prediction results in local areas are demonstrated to be more accurate if considering the spatial autocorrelations.  相似文献   

Asian international students’ help-seeking intentions and behavior in American Postsecondary Institutions     

《Int J Intercult Relat》2021

While the number of Asian international students has increased in postsecondary institutions in the United States over the last two decades, unlike their American peers, these students were reported to have more severe mental health issues with less help-seeking intentions and behavior. This study drew the national data collected by American College Health Association-National College Health Assessment (ACHA-NCHA) from 2011 to 2014 to examine how various factors were associated with help-seeking intentions and behavior among Asian International Students (AIS) in the U.S. After case-wise deletion of missing data, the dataset used in regression analyses included 97,259 college students, including 2999 AISs, who were randomly drawn within the 62 participated postsecondary institutions. The study performed a series of logistic regression with complex survey design that controlled for institutional clustering effects to analyze the relationship between various factors and AISs’ help-seeking intentions and behavior. The results showed that AIS utilized significantly less services and were less willing to seek mental health services than not only American domestic students but also other international students. Variables related to institutional characteristics, demographic information, academic status, and health conditions were found to significantly influence AISs’ help-seeking intentions and behavior. College mental health professionals and university stakeholders need to pay more attention to the mental health needs of AIS. Implications for college mental health professionals and university stakeholders are discussed.  相似文献   

改革开放40年高等体育教育资源优化配置的社会学审视     

张孔军  钱娅艳 《北京体育大学学报》2019,42(2):103-114

摘要：我国高等体育教育资源优化配置研究引入社会学视角理论与方法，理论与实践均取得专家的认同。运用文献资料法、专家访谈法和实地考察法等方法发现，在计划经济体制下我国高等体育教育资源配置主体单一性、手段行政化和政治倾向性强，凸显出高等体育教育资源配置缺乏激励机制和市场竞争机制的问题，造成高等体育教育资源配置成本最大化和社会效应的最小化问题较多。自改革开放以来,随着我国市场经济体制的建立为高等体育教育资源优化配置提供了难得的发展机遇，我国高等体育教育资源配置取得了明显成效，但仍然存在高等体育教育资源配置机制滞后、体制机制改革创新步伐缓慢、高等体育教育资源配置不合理以及民办普通高校体育教育资源配置严重不足等问题。据此，从社会学研究的视角，提出了构建多主体推动高等体育教育资源优化配置创新的发展模式、多元化高等体育教育资源优化配置资金投入的保障体系、高等体育教育资源优化配置均衡发展的运行机制和大学城体育教育资源“共建共享”的创新发展模式的新时代我国高等体育教育资源优化配置的发展策略，旨在服务新时代全民健身与全民健康深度融合发展，“推动构建人类命运共同体”发展目标的实现。  相似文献   

群众体育发展模式的结构创新     

史兵  丁建岚  钱钧  杨小帆  万丙智 《北京体育大学学报》2019,42(2):36-45

摘要：群众体育是我国体育事业的重要组成部分，经多年发展，逐步形成了“政府主导、部门协同、全社会共同参与”的发展模式。随着市场经济改革进一步深化，我国社会主要矛盾转化为人民日益增长的美好生活需要和不平衡不充分的发展之间的矛盾，现有群众体育发展模式已无法满足人民对健康生活的追求，迫切需要在国家治理体系层面上对其进行改革完善。通过文献资料分析法，对群众体育发展模式的结构进行剖析，对未能明确的主要问题进行梳理，发现现有模式存在主体不明、承担者模糊、发展方式单一，体育社会组织参与不够等问题。由此，提出群众体育发展模式的新思路及结构模型，明确政府、社会组织、市场在群众体育发展模式当中各自的作用、发展主体及性质。群众体育“政府引导、社会参与、公民主体、市场推动”的发展新模式将成为新时代体育事业发展的源动力。暨人民中心和公民主体地位充分体现，政府引导方式和责权范围明晰，体育社会组织参与主办承办者身份明确，社会自我组织有效管理，市场参与度高，体育服务供给丰富。以期对我国群众体育的长效发展提供建议及切实有效的发展路径，深入落实全民健身战略，提高人民健康水平。  相似文献   

学术乃天下之公器——哈佛燕京图书馆馆长郑炯文访谈     

谢欢 《中国图书馆学报》2020,46(4):126-131

2019年7月22日,南京大学谢欢博士对哈佛燕京图书馆馆长郑炯文先生就北美东亚图书馆发展相关问题进行访谈。东亚图书馆肇始于欧洲,起源于传教士对文史哲印刷文献的专题收集,与汉学发展紧密相关；美国东亚图书馆在第二次世界大战后取得了快速的发展,如今美国已成为西方世界东亚研究的中心。华人图书馆员是北美东亚图书馆从业人员中非常重要的群体,三代华人图书馆员各具专长,为北美东亚图书馆发展做出了贡献。郑炯文先生自担任哈佛燕京图书馆馆长以来,主要致力于以下三方面工作:①整理裘开明、吴文津担任馆长期间收集的文献；②开放馆藏,将哈佛燕京图书馆的资源面向全世界学者开放；③推动中美图书馆员交流合作项目。  相似文献   

Teaching for social justice: A research synthesis on Asian American and Pacific Islander teachers in U.S. schools     

《Teaching and Teacher Education》2020

This article examines social justice in teaching and teacher education with a focus on the experiences, pedagogies, and instructional practices of Asian American and Pacific Islander (AAPI) teachers. We synthesized 37 peer-reviewed research publications on AAPI teachers’ experiences and contributions to diversity and social justice. The results show AAPI teachers disrupting Whiteness through beliefs, pedagogies, and practices that value multiple perspectives and marginalized voices. Policy implications include supporting cultural and linguistic diversity in teacher education programs and schools and providing opportunities for teachers to engage in critical praxis regarding their racial identities and issues of equity in education.  相似文献

Is academic tracking related to gains in learning competence? Using propensity score matching and differential item change functioning analysis for better understanding of tracking implications     

《Learning and Instruction》2020

This study analyzes gains in cognitive components of learning competence with respect to cohorts based on ability tracking in a Czech longitudinal study. Propensity score matching is used to form parallelized samples of academic and non-academic track students and to eliminate the effect of selective school intake. We applied regression models on the total scores to test for the overall track effect. Furthermore, we analyze scores and gains on the subscores and check for differential item functioning in Grade 6 and in change to Grade 9. While after 3 years, no significant difference between the two tracks was apparent in the total learning competence score, we did, however, find significant differences in some subscores and in the functioning of some items. We argue that item-level analysis is important for deeper understanding of the tracking implications and may provide the basis for more precise evidence-based decisions regarding the tracking policy.  相似文献

培养湖州新农村“专业农民”的对策     

郑宁国  许伟达  王柱国 《湖州职业技术学院学报》2011,9(2):5-8

在“十一五”期间,湖州市新农村建设在科技创新、产业发展、村镇规划建设、基础设施建设、生态环境建设等方面培养了大批“三农”人才,创建了新农村建设的“湖州模式”。这为贯彻落实中共中央国务院《国家中长期人才发展规划纲要（2010—2020年）》“以用为本”的精神打下了扎实的基础。作为目前参与湖州“美丽乡村”建设活动的新农民——农村领军人才,必须学习现代科学知识,围绕湖州农业主导产业发展方向,将自己培养成“专业农民”,让技术变成看得见、摸得着的产业,以增强农业产业化组织的带动能力,发挥专业合作社对广大农户的影响力和带动力。  相似文献
