How and why are educators using Instagram?     

《Teaching and Teacher Education》2020

Social media are commonplace in many educators’ lives, but their Instagram activities have received no prior attention in the empirical literature. We therefore created and disseminated a survey regarding educators’ Instagram use. Analyses of 841 responses suggested participants were generally intensive users of Instagram who engaged in the exchange of both professional knowledge and wisdom, as well as affective support. In addition to identifying benefits to Instagram use, some participants offered critiques of Instagram’s professional utility. We discuss the implications of these findings for educators’ work in a digital era and the future of research on educators’ social media activities.  相似文献   

重大体育赛事对城市经济发展的影响--基于中国70个大中城市面板数据分析     

毛丰付  郑芳  朱书琦 《上海体育学院学报》2020,(5):24-36

重大体育赛事的举办在一定程度上能推动承办城市转型发展,但也可能对当地经济产生某种不良影响,这主要源于对重大体育赛事与城市经济发展的内在规律和作用机制认识不够清晰。以2000-2017年22项具有全国影响力的重大体育赛事为基础,利用中国70个大中城市面板数据,采用双重差分法,分析重大体育赛事对城市经济发展的影响。发现:全样本数据下重大体育赛事的举办会促进城市第一产业向第二、第三产业发展;对比国内和国际赛事,重大体育赛事对第三产业的促进作用均显著高于第二产业;以1 085家上市公司数据为样本,采用事件研究法进行分析,发现不同行业利用重大体育赛事的窗口期存在显著差异。  相似文献   

官员任期、政策偏好与城市创新     

邓洁潘爽  叶德珠 《科研管理》2023,44(1):114-124

晋升锦标赛下，官员在有限任期内存在晋升预期差异，由此导致的短视行为的变化可能对创新产出造成影响。然而现有文献并未从官员晋升动机视角深入研究城市创新的制度动因，也未曾厘清官员任期等政治体制对创新活动的具体影响机制。本文利用2004—2016年285个城市的面板数据，通过多元统计回归分析，实证检验了官员任期如何通过经济增长目标影响城市创新的机制路径，并从土地财政、环境治理视角提出了新机制路径。研究发现：(1)相对于市长，市委书记任期对城市创新的影响更大，且呈现出显著的倒U型关系；(2)市委书记的更替显著抑制了城市创新水平的提升；(3)机制分析发现，市委书记的任期通过动态影响经济增长目标制定，土地财政依赖以及环境治理水平进而对城市创新产生影响。譬如当经济增长目标越高，官员越倾向于采用短视的扩张策略刺激经济，进而减少对创新活动的投入；(4)异质性分析发现在市场化条件较好，东部以及城市规模较大的地区，市委书记任期对创新的U型特征仍然显著。本文建议政府在推进财政分权体制改革时，应采用因地制宜的推进方式，将“有效市场”与“有为政府”更好地结合起来。本文研究结论丰富了晋升锦标赛理论的经验证据，有助于理...  相似文献   

基于生态位理论的高校众创空间建设策略研究     

张超  张育广 《科技管理研究》2019,39(8)

高校众创空间作为高校创新创业人才培养的新兴重要载体，对高校创新创业教育具有重大作用。在创新驱动发展战略背景下，各高校结合自身优势对众创空间建设模式进行了各具特色的实践探索，但在理论研究方面仍缺乏科学梳理和系统思维，在空间布局和功能定位上，缺乏从生态系统的视角打造高校创新创业生态系统。本文通过阐释众创空间的内涵，分析高校众创空间的存在问题，在高校创新创业教育的实践经验基础上，探索以生态位理论视角剖析众创空间的系统结构模型以及要素互动关系，提出高校众创空间生态系统构建的建设策略，全面提升高校众创空间的科学发展。  相似文献   

Sexual choreographies of the classroom: movement in sexuality education     

Louisa Allen 《Discourse: Studies in the Cultural Politics of Education》2018,39(3):347-360

This paper is interested in thinking more about sexuality education at school. As such, it is concerned with a mundane and unacknowledged feature of the sexuality classroom – the mapping of movement. While human movement is a familiar focus of educational research, the movement of things is not. With reference to Barad’s concept of intra-activity, the paper maps human-non-human movements and characterises these as a sexual choreography of schooling. Instead of asking what does movement mean or reveal about sexuality education, I attend to the event movement inaugurates. Predominantly theoretical, the paper weaves together ideas from conventionally disparate disciplinary fields. These include Edensor’s concept of rhythm from geography, Eggermont’s notion of the choreography of schooling from education, and Barad’s spacetimemattering from quantum physics. This theorisation enables a recognition of movement as a force in human-non-human classroom intra-actions implicated in the becoming of sexuality education as event.  相似文献   

众创空间投入与区域科技创新发展关系实证研究     

宋宏  张璐 《科技管理研究》2018,(12)

以众创空间投入及其所在区域科技创新发展状况为对象,以科技进步贡献率为衡量科技创新能力指标,基于线性回归方法和向量自回归模型分析西安市众创空间投入的创新效果及其与西安市科技进步贡献率之间的关系。研究结果表明:加大众创空间投入可以更好地提升众创空间孵化效率,产生良好的创新效果,且该创新效果与科技创新发展之间存在长期正相关关系;科技进步对众创空间创新效果指标的预测方差贡献较大,众创空间对科技发展的预测方差贡献较小。建议采用合理的融资模式与政策组合鼓励建设众创空间,并使用科学合理的运营模式提升众创空间盈利能力,以期获得众创空间良好的创新效益及社会效益。  相似文献   

Dialogic processes that enable student teachers' learning about pupil learning in mentoring conversations in a Lesson Study field practice     

《Teaching and Teacher Education》2018

This study investigates dialogic processes in student teachers' mentoring conversations in field practice, where Lesson Study (LS) was used as a context for establishing a dialogic learning community in one student group in science. We apply an analytical framework associated with Sociocultural Discourse Analysis to identify utterances that have the potential to create a dialogic space and contribute to ‘interthinking’ among the participants. The findings show the important role of the mentor teacher as a facilitator and a ‘knowledgeable other’, challenging the student teachers to reflect on chosen activities using predictions and detailed observations related to pupils' learning.  相似文献   

技术创新影响产业结构的空间传导路径分析     

江三良  纪苗 《科技管理研究》2019,39(13)

在理论分析技术创新影响产业结构优化升级路径的基础上，构建技术创新评价指标，引入三种不同类型空间权重，选取2000-2015年我国30个省级面板数据进行空间杜宾模型实证检验，结果表明：技术创新不仅促进了本地产业结构，还有助于邻近地区合理化发展，但对邻近地区高级化的抑制作用和促进作用并存；省域间技术创新和产业结构具有显著空间相关性，产业结构高级化存在正向溢出效应而产业结构合理化却有着负向溢出效应；技术创新能够通过一条直接路径和空间效应形成的三条间接路径作用于本地及其他地区产业结构；技术创新对产业结构的作用方向和强度存在较大区域差异。据此，加强技术创新提升产业结构结构的“先富带后富”，是可以通过政策引导实现的。  相似文献

The temporal pocket: 1990s Beijing artist colonies     

Christen Cornell 《Inter-Asia Cultural Studies》2018,19(1):58-71

In recent years, a small but growing body of scholarship has emerged on the category of the Chinese art district, particularly its institutionalisation amidst twenty-first century creative industries polices. Such research presents important stories of Chinese artists’ negotiations with urban and political authority, thus nuancing paradigms for the comprehension of political work within contemporary China. This current article contributes to this growing research area by considering the spatial conditions for these socio-spatial categories’ emergence, namely, the urban structures in which they first took shape in 1990s Beijing. First occupying traditional villages (cunzi) and later ex-socialist work units (danwei), these arts colonies appropriated existing communal architecture, and turned their designs and physical buildings to their own communal ends. Importantly, these sites were made available by the dramatic reconstruction of the city, and in this sense these occupations were limited to the temporal realm. To describe the nature of occupations, and their eventual impact upon the shape of the city, this paper proposes the category of “the temporal pocket”: a cellular and temporary inhabitance, defined by the shared investments of its participants, and one that is both discrete (in the sense of its spaces) and discreet (in the sense that this can be understood as a non-oppositional politics). The article is informed by spatial and cultural theory, literature on Chinese urban planning and art history, as well as primary documents (such as documentaries, art works and archival material) and interviews conducted by the researcher in Beijing.  相似文献
