学术博客用户知识共享意愿的影响因素研究--以科学网博客为例

学术博客用户知识共享意愿受到多种因素影响,本文以科学网博客为例,结合基于个体与环境交互的自我概念理论和基于人际交换关系的传统动机理论构建研究模型。通过调查问卷搜集数据和运用结构方程模型进行实证研究,结果表明内部自我概念、外部自我概念、社会关系互惠、形象、自我价值感知和乐于助人对学术博客用户知识共享意愿均具有显著影响。     

智慧城市建设视角下资源环境承载能力提升路径研究

基于熊彼特创新理论,论证了智慧城市建设对资源环境承载能力的影响机制,利用陕西省2015—2019年的面板数据,结合结构方程模型（SEM）与模糊集定性比较分析法(fsQCA),探索智慧城市建设各维度对资源环境承载能力的影响及多维度间“联合效应”与“互动关系”。研究发现：①智慧环境、智慧人力资本和智慧经济对资源环境承载能力有显著正向效应。②智慧经济在推动资源环境承载能力可载中起到了关键作用。③存在经济拉动型、环境治理型、绿色发展型和创新驱动型等四条智慧城市建设路径可以提升资源环境承载能力,具体可归纳为产业升级推动式和环境规制拉动式。④在一定情形下智慧经济与智慧治理、智慧环境之间具有替代关系。本研究深化了现有智慧城市建设效应理论研究,并为以提升资源环境承载能力为导向的智慧城市建设提供了差异化的方案。     

新型微带环慢波结构的研究

提出了一种新型微带慢波结构:微带环结构,对其高频特性进行了研究,采用微米量级的结构尺寸,将带宽拓展到毫米波段。通过利用电磁场仿真软件HFSS对该结构进行模拟计算,得到了各个结构参数下慢波电路的色散特性和耦合阻抗,分析了结构参数对其高频特性的影响。对微带环加杆结构的情况也进行了分析。得到对高频特性影响较大的结构参数,能够为器件的进一步研究提供指导参考。     

偏心受压桩简化计算方法

建筑地基基础设计规范(GB50007-2002)给出的桩身计算方法对轴心受压桩很适用,而对偏心受压桩计算就非常繁琐。本文给出偏心受压桩一种简化计算方法和工程应用实例。     

谈如何提高结构化学的教学

结构化学是师范院校化学专业的基础课程之一,因其较强的理论性,一直被学生视为最难学的课程,根据教学实践的体会,分别从如何提高课堂教学质量、结合学生反馈、利用多媒体辅助教学、引导学生自主学习四个方面进行了分析和讨论,对如何提高结构化学的课堂教学提出了自己的意见。     

民工荒与大学生就业难的结构性矛盾浅议

目前,我国劳动力市场存在民工短缺和大学生就业困难的结构性矛盾,折射出我国经济增长方式和产业结构的不合理以及劳动力市场分割和资源配置效率低下的问题。同时,民工荒和大学生就业难二者自身也存在结构性矛盾,需要国家宏观的战略调整和有关各方的切实努力。     

Fifty years of information management research: A conceptual structure analysis using structural topic modeling

Information management is the management of organizational processes, technologies, and people which collectively create, acquire, integrate, organize, process, store, disseminate, access, and dispose of the information. Information management is a vast, multi-disciplinary domain that syndicates various subdomains and perfectly intermingles with other domains. This study aims to provide a comprehensive overview of the information management domain from 1970 to 2019. Drawing upon the methodology from statistical text analysis research, this study summarizes the evolution of knowledge in this domain by examining the publication trends as per authors, institutions, countries, etc. Further, this study proposes a probabilistic generative model based on structural topic modeling to understand and extract the latent themes from the research articles related to information management. Furthermore, this study graphically visualizes the variations in the topic prevalences over the period of 1970 to 2019. The results highlight that the most common themes are data management, knowledge management, environmental management, project management, service management, and mobile and web management. The findings also identify themes such as knowledge management, environmental management, project management, and social communication as academic hotspots for future research.     

旅游从业者工作休闲冲突对工作倦怠影响研究——基于结构方程模型的实证分析

相较于其他行业从业者,旅游从业者的工作—休闲冲突和工作倦怠更为激烈,而较少研究者运用结构方程模型研究该问题。文章以古村落旅游从业者为研究对象,通过问卷调研获得第一手数据,运用结构方程模型探讨工作—休闲冲突对工作倦怠的影响。实证结果显示,工作—休闲冲突与工作倦怠的情绪耗竭、去个性化和职业效能感降低维度正向显著相关。在不考虑其他因素的前提下,工作—休闲冲突越大,旅游从业者的工作倦怠感越强。因此旅游企业可以通过缓解工作—休闲冲突来干预从业者的工作倦怠。     

Creating (in) equalities in access to higher education in the context of structural adjustment and post-adjustment policies: the case of chile

By analyzing the access of different socio-economic groups to post-secondary institutions by quintile, this paper examines the impact produced by higher education financing policies in Chile during the Pinochet (1973–1990), the Aylwin (1990–1994) and the Frei (1994–2000) administrations. To this purpose, CASEN databases and semi-structured interviews conducted with former and current government officials as well as higher education administrators provide valuable information to measure the impact that higher education financing policies had on different socio-economic groups. Access to post-secondary institutions is seen in relation to two aspects: (a) enrollment rates by type of institution and sector and (b) access of students (18–24 year-old group) by family per capita income level. Major conclusion set up that despite increased participation across all socio-economic groups within the post secondary system, upper and upper-middle income students gained access to higher education disproportionately compared to lower, lower-middle, and middle income groups during the 1987–1998 period.

高复生的心理健康和应急事件状况及社会支持在两者间的作用机制

采用症状自评量表（SCL-90）、社会支持评定量表（SSRS）和青少年生活事件量表（ASLEC）对450名高考复习生进行测评,再应用结构方程模型技术对社会支持的中介效应进行检验。分析结果表明,高复生心理健康水平比常模差,并且比应届高三学生有更大的应激强度;社会支持在负性生活事件和心理健康之间起中介作用,占总效应的9．5％。
