[目的/意义]探究社交媒体倦怠的原因要素和结果要素标签，分析各要素间的相互作用关系，扩展用户信息行为的理论研究范畴，为企业深入了解用户社交媒体倦怠发展态势提供指导。[方法/过程]基于信息生态理论，提取"信息人、信息、信息环境和信息技术"4个信息生态因子维度的社交媒体用户画像标签；根据用户心理特征和行为表现，抽取用户画像情感和行为标签，构建社交媒体倦怠用户画像模型。[结果/结论]透过社交媒体用户消极使用和负面情感变化的典型社会现象，对用户画像模型进行整合分析与关系凝练，证明本研究社交媒体倦怠用户画像模型与S-S-O理论框架具有一致性，并根据实际进行理论上的拓展和应用。  相似文献   

Designing Curriculum-Based Mathematics Professional Development for Kindergarten Teachers     

Drew Polly  Christie S. Martin  Jennifer R. McGee  Chuang Wang  Richard G. Lambert  David K. Pugalee 《Early Childhood Education Journal》2017,45(5):659-669

This study examines the influence of a year-long mathematics professional development program on Kindergarten teachers’ beliefs, content knowledge, instructional practices, and their students’ achievement. The professional development program is grounded in the theoretical construct of learner-centered professional development and focuses on supporting teachers’ integration of standards-based pedagogies aligned with the Common Core State Standards in Mathematics. Data analysis included examining 15 Kindergarten teachers’ mathematics content knowledge, their beliefs about mathematics, their enactment of student-centered pedagogies, and student achievement on curriculum-based assessments. Findings indicated that teachers adopted more student-centered pedagogies and embraced more student-centered beliefs about mathematics teaching during their time in the project. Further, Kindergarten teachers also demonstrated gains in their mathematical content knowledge, and those content knowledge gains were linked to gains in student achievement.  相似文献

高等职业教育师资队伍建设途径     

王闯  王爱玲 《职业技术教育》2007,(23):55-56

高职师资队伍建设中存在专任教师学历偏低、结构欠合理、"双师型"教师匮乏、相应培训滞后等问题。改善师资队伍,需在优化师资队伍结构,建立相对稳定的兼职教师队伍,寻求校企联合办学,培养"双师型"教师等方面下工夫。  相似文献

企业家职业倦怠及基于社会责任的消解前因——情商与领导风格的调节作用     

辛杰  吴创 《科学学与科学技术管理》2015,(7)

以431位中国企业家为调查研究对象,实证中国企业家的职业倦怠现状及群体差异,并基于社会责任视角探索企业家社会责任的消解前因。CSR1对企业家职业倦怠的三个维度(人格解体、情绪衰竭、无效能感)都有显著负向影响,CSR2对人格解体有显著负向影响,CSR3对企业家职业倦怠的三个维度都不具有显著负向影响。变革型领导会加强CSR1对企业家职业倦怠的三个维度以及CSR2对人格解体的消解影响,而交易型领导仅会加强CSR2对人格解体的消解影响,情商会加强CSR1对情绪衰竭、无效能感以及CSR2对人格解体的消解影响。企业家要消解职业倦怠,应主要依赖于CSR1(优势利益相关者责任)的履行,培养和加强变革型领导风格,提升情商水平。  相似文献   

Numerical simulation on the opto-electro-kinetic patterning for rapid concentration of particles in a microchannel     

Dong Kim  Jaesool Shim  Han-Sheng Chuang  Kyung Chun Kim 《Biomicrofluidics》2015,9(3)

This paper presents a mathematical model for laser-induced rapid electro-kinetic patterning (REP) to elucidate the mechanism for concentrating particles in a microchannel non-destructively and non-invasively. COMSOL^®(v4.2a) multiphysics software was used to examine the effect of a variety of parameters on the focusing performance of the REP. A mathematical model of the REP was developed based on the AC electrothermal flow (ACET) equations, the dielectrophoresis (DEP) equation, the energy balance equation, the Navier-Stokes equation, and the concentration-distribution equation. The medium was assumed to be a diluted solute, and different electric potentials and laser illumination were applied to the desired place. Gold (Au) electrodes were used at the top and bottom of a microchannel. For model validation, the simulation results were compared with the experimental data. The results revealed the formation of a toroidal microvortex via the ACET effect, which was generated due to laser illumination and joule-heating in the area of interest. In addition, under some conditions, such as the frequency of AC, the DEP velocity, and the particle size, the ACET force enhances and compresses resulting in the concentration of particles. The conditions of the DEP velocity and the ACET velocity are presented in detail with a comparison of the experimental results.  相似文献
