Why care about caring? Linking teachers’ caring and sense of meaning at work with students’ self-esteem,well-being,and school engagement     

《Teaching and Teacher Education》2020

Research on teacher-student relationships shows their impact on students. However, it typically focuses on teachers’ interactions and instruction, with less attention to motivations/feelings. Specifically, almost no quantitative research has focused on teachers’ caring for students, despite its potential importance. The present multilevel study, comprising 675 students in ages 15–17 and their 33 homeroom teachers, linked students’ feelings that their teacher cares for them with their self-esteem, well-being, and school engagement and indicated that teacher-student relationships quality mediates these links. Furthermore, students’ reports on teachers’ caring were associated with teachers’ sense of meaning at work, suggesting its role in enhancing caring.  相似文献   

Understanding the topic evolution of scientific literatures like an evolving city: Using Google Word2Vec model and spatial autocorrelation analysis

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   

一种基于模糊语言TOPSIS的应急决策方法     

李海明  虞钢  田崇鑫  尚国彬 《中国科学院大学学报》2020,37(6):814-819

在应急决策过程中，决策信息通常具有犹豫性、模糊性和非对称性，且决策者呈现出直观、快速的语言决策偏好。提出一种基于模糊语言TOPSIS的应急决策方法，使用犹豫模糊语言术语集和二元语义表达式对高度不确定环境下的语言进行处理，提高对犹豫模糊语言信息的提取能力，生成易于理解的语言评估结果，从而辅助决策者进行快速、准确的决策判断。案例证实该方法的可行性与有效性，为解决应急决策问题提供了一种新方法。  相似文献

一个农民·一座城市·一部心灵成长史——刘玉栋长篇新作《年日如草》研讨     

张丽军  房伟 《海南师范大学学报(社会科学版)》2011,24(3):102-108

在长篇小说创作凋零和缺失状况下,刘玉栋《年日如草》的出版,对于刘玉栋本人和整个70后作家群来说,都是一个很重要的突破。从＂二十世中国文学史＂的角度来看农民与城市的关系,农民如何融入城市、进入城市是一个现代化、城市化的中心问题。刘玉栋的《年日如草》塑造了一个适应现代城市生活的二代农民形象,一个带有某种狡黠而不失善良本性的、以法律取代人情意识的农民形象。这是以往文学史所没有的,具有突破性意义。  相似文献   

出生性别比研究——以福建省为例     

王娜 《湖州职业技术学院学报》2011,9(3):49-51

利用全国人口普查福建省数据和福建省公开发布的有关资料数据,分析福建省出生性别比失衡现象的现状,在此基础上,从社会性别视角分析得出出生性别比失衡的根源为性别不平等。应从转变传统观念、充分发挥社会化主体的作用以及借鉴韩国有效的经验三个方面采取有效措施,才能更好地解决出生性别比问题。  相似文献   

从英汉两种语言的差异看两种文化内涵的不同     

康洁 《太原大学教育学院学报》2007,25(1):82-84

语言是文化的一部分，它就像文化的基石。语言反映着一个民族的特征。它不仅包括着该民族的历史和文化背景。而且蕴藏着该民族对人生的看法、生活方式和思维方式。语言与文化相互影响，相互作用。了解语言必须理解文化。理解文化有助于我们更好地了解语言。  相似文献
