COVID-19, digital privacy,and the social limits on data-focused public health responses     

《International Journal of Information Management》2020

The implementation of digital contact tracing applications around the world to help reduce the spread of the COVID-19 pandemic represents one of the most ambitious uses of massive-scale citizen data ever attempted. There is major divergence among nations, however, between a “privacy-first” approach which protects citizens’ data at the cost of extremely limited access for public health authorities and researchers, and a “data-first” approach which stores large amounts of data which, while of immeasurable value to epidemiologists and other researchers, may significantly intrude upon citizens’ privacy. The lack of a consensus on privacy protection in the contact tracing process creates risks of non-compliance or deliberate obfuscation from citizens who fear revealing private aspects of their lives – a factor greatly exacerbated by recent major scandals over online privacy and the illicit use of citizens’ digital information, which have heightened public consciousness of these issues and created significant new challenges for any collection of large-scale public data. While digital contact tracing for COVID-19 remains in its infancy, the lack of consensus around best practices for its implementation and for reassuring citizens of the protection of their privacy may already have impeded its capacity to contribute to the pandemic response.  相似文献   

Assessing library topics using sentiment analysis in R: a discussion and code sample     

Brady D. Lund 《Public Services Quarterly》2020,16(2):112-123

Abstract

This article discusses the use of R programing language for executing a sentiment analysis of tweets pertaining to library topics. This discussion is situated within the literature of marketing and management sciences, which is employing methods of machine learning and business intelligence to make informed decision-making, and library administration, which has expressed great interest in social media engagement within its literature but has yet to adopt these types of analysis. Presented in this article is a sample code with instructions on how users may execute it within R to retrieve and analyze tweets relevant to library services. Two examples created using the code (analysis of top librarians’ tweets and analysis of posts about major book publishers) are used to demonstrate the functionality of the code. The code presented in this article may be used by libraries to analyze tweets about their library and library-related topics, which, in turn, may inform management and marketing design.  相似文献

我国学校体育场地建设效率研究     

孙成林  王健 《武汉体育学院学报》2020,54(2):44-52

基于第六次全国体育场地普查基础数据，运用数据包络分析法，对我国学校体育场地建设效率进行研究。结果显示：在样本期内，学校体育场地建设的综合技术效率均值为0.606、纯技术效率均值为0.758、规模效率均值为0.787，较之DEA最优值1，我国学校体育场地的建设效率不高；以非DEA有效为标准，从综合技术效率看，学校体育场地建设效率呈现东部高于西部、西部高于中部地区的态势，场地建设投入决策单元的整体效率水平不高；从纯技术效率看，体育场地建设效率呈现西部高于东部、东部高于中部地区的态势，场地建设投入要素的管理和技术水平有较大提升空间；从规模效率看，体育场地建设效率呈现与综合技术效率同样的态势，且全国有23个省体育场地建设处于规模效益递减状态，场地建设投入资源的配置效率不高。分析表明我国学校体育场地建设效率低的原因主要在于场地建设投入资金的结构不合理、区域间体育资源的配置不合理、体育用地开发利用的"二维平面延展"局限性等。建议：在财政经费投入上采用差异化的财政投入政策，在区域性资源配置上合理配置区域间学校体育场地建设投入资源，在土地资源开发利用上注重学校体育用地的"三维立体化"开发等举措，以提高我国学校体育场地的建设效率。  相似文献   

质性评价:另一种学生学业评价方法     

苑毅 《教育教学论坛》2020,(19):360-361

量化评价是基于自然科学主义观点对学生学业开展评价,它将学生作为统一的整体忽略了个体之间的差异,而基于人文主义的质性评价则注重学生之间的个体差异。质性评价为职业教育中的学业评价提供了另一种好思路,值得研究和推广。  相似文献   

Towards a Framework for Evaluating the Research Performance of Chinese Double First-Class Universities     

XU Changqing 《Frontiers of Education in China》2020,15(3):369

The study focuses on the research performance of Double First-Class (DFC) universities in China. A theoretical framework based on economic theory and the Analytic Hierarchy Process (AHP) method for a novel evaluation model is proposed. The model is performed on a sample of 41 participant DFC universities in China. Using data collected from these universities, it was found that there is no consistency between performance ranking, input ranking, and output ranking, with the best ranked universities far from the most efficient. These findings provide empirical evidence of DFC universities’ research performance situation and suggest strategies that the government can use to propel their sustainable development.  相似文献   

Uncharted territory and extraordinary times: the SENCo's experiences of leading special education during a pandemic in England     

Tristan Middleton  Lynda Kay 《British Journal of Special Education》2021,48(2):212-234

This research focuses on the impact of the context of Covid-19 on the role of the SENCo in English schools. The SENCo's role is a contested field; however, the current Special Educational Needs Code of Practice identifies 11 key areas of SENCos' work. A widely distributed survey was used to access the voice of SENCos across the country, and received 26 responses. Data were analysed using a realistic evaluation framework to identify the impact of Covid-19 on the work of the SENCo. The research indicated that practice in this context had changed in some key areas, and also identified three new aspects of the SENCo role. These point to the need to revise policy and guidance relating to the SENCo being part of the senior leadership team, providing emotional support for adults, and engaging in practical pedagogical activities.  相似文献   

Utilizing program theory and contribution analysis to evaluate the development of science teacher leaders     

《Studies in Educational Evaluation》2014

This paper illustrates how theory of change coupled with contribution analysis assisted in delineating the role each aspect of a teacher professional development program contributed to the expected outcomes. Using a mixed methods evaluation based upon the theory of change, data was gathered on 12 teacher leaders over three years. Findings indicated that not only did the teachers continue to develop as leaders over the three year project but also that the interventions designed to provide professional development to the teachers did indeed contribute to the attainment of project outcomes. By combining stakeholders’ theory of change with contribution analysis, evaluators can develop an understanding of program intentions and design an evaluation that enhances the validity of findings.  相似文献
