Machine learning based system for managing energy efficiency of public sector as an approach towards smart cities     

《International Journal of Information Management》2021

Energy efficiency of public sector is an important issue in the context of smart cities due to the fact that buildings are the largest energy consumers, especially public buildings such as educational, health, government and other public institutions that have a large usage frequency. However, recent developments of machine learning within Big Data environment have not been exploited enough in this domain. This paper aims to answer the question of how to incorporate Big Data platform and machine learning into an intelligent system for managing energy efficiency of public sector as a substantial part of the smart city concept. Deep neural networks, Rpart regression tree and Random forest with variable reduction procedures were used to create prediction models of specific energy consumption of Croatian public sector buildings. The most accurate model was produced by Random forest method, and a comparison of important predictors extracted by all three methods has been conducted. The models could be implemented in the suggested intelligent system named MERIDA which integrates Big Data collection and predictive models of energy consumption for each energy source in public buildings, and enables their synergy into a managing platform for improving energy efficiency of the public sector within Big Data environment. The paper also discusses technological requirements for developing such a platform that could be used by public administration to plan reconstruction measures of public buildings, to reduce energy consumption and cost, as well as to connect such smart public buildings as part of smart cities. Such digital transformation of energy management can increase energy efficiency of public administration, its higher quality of service and healthier environment.  相似文献

挑战、困境与化解:数字环境下我国图书馆合理使用条款及其适用的再探讨     

王果  张立彬 《图书情报工作》2019,63(10):5-11

[目的/意义] 合理使用是维持著作权人个人利益与社会公共利益平衡的重要机制之一，对承担公共文化服务功能的图书馆尤为重要，但实践中图书馆的合理使用条款并未充分发挥利益平衡的作用，有必要对其存在问题及形成原因进行深入分析。[方法/过程] 通过与域外立法相比较，以及司法实践中的案例分析，可看出我国图书馆合理使用的主要问题在于现行法律规定滞后、规则不明晰，导致合理使用适用范围狭窄，还同时受到许可协议、技术措施的挤压。[结果/结论] 为化解图书馆合理使用条款的适用困境，可从增加原则性规定、明确其法律属性为强制性规定、扩大有关条款的适用范围等方面来完善立法。图书馆自身也应加强知识产权管理、提高知识产权素养，严格遵照法律规定以消除侵权隐患。  相似文献

登上领奖台：加拿大冬奥备战的治理经验及其启示     

任慧涛  楚金玲  易剑东 《南京体育学院学报(社会科学版)》2019,2(1):39-49

为备战2010年温哥华冬奥会，加拿大联邦政府设计了“登上领奖台”战略，委托OTP组织负责财政援助的划拨和绩效管理。OTP组织采用“决策层—执行层”的双层治理架构，以“奖牌至上”为原则，创建了由“项目文化”“以往成绩”“夺牌潜力”“领先优势的可持续性”4个一级指标的协会分层分类资助制度，邀请国家奥委会和残奥委、国家运动项目协会、体育科研院所等利益相关者组成协同治理网络。通过梳理加拿大治理经验，建议我国当前的备战2022年北京冬奥工作，应重视“一臂之距”理念，明确政府在冬奥备战中的职责；尊重专业自治准则，锻炼社会力量成为竞技体育治理主体；改进绩效管理模式，优化冬奥备战财政资金的申请和使用程序；重视科学创新，促进体育智库组织网络化。  相似文献   

Data Visualization as Participatory Research: A Model for Digital Collections to Inspire User-Driven Research     

A. Miller 《Journal of Web Librarianship》2019,13(2):127-155

The emerging creative practices of digital collections are increasing in prominence thanks to the access to, and appeal of, data visualizations. Interactive data visualizations, such as a map, timeline, chart, graph, or artist’s rendering of data, enable users to pursue their own research interests within a collection and participate in new areas of research. Use of these data visualizations enhances the scope of the collection and enables a modern and diverse thematic collection to emerge. This article considers the question: Does the addition of data visualizations affect how users participate with a research collection? Impacts on collection development, application of user-centered design, and analysis of users’ exploratory strategies are discussed. Examples of data visualizations used in digital humanities projects and digital collections are presented as case studies.  相似文献   

Impact of digital surge during Covid-19 pandemic: A viewpoint on research and practice     

《International Journal of Information Management》2020

The Covid-19 pandemic has led to an inevitable surge in the use of digital technologies due to the social distancing norms and nationwide lockdowns. People and organizations all over the world have had to adjust to new ways of work and life. We explore possible scenarios of the digital surge and the research issues that arise.An increase in digitalization is leading firms and educational institutions to shift to work-from-home (WFH). Blockchain technology will become important and will entail research on design and regulations. Gig workers and the gig economy is likely to increase in scale, raising questions of work allocation, collaboration, motivation, and aspects of work overload and presenteeism. Workplace monitoring and technostress issues will become prominent with an increase in digital presence. Online fraud is likely to grow, along with research on managing security. The regulation of the internet, a key resource, will be crucial post-pandemic.Research may address the consequences and causes of the digital divide. Further, the issues of net neutrality and zero-rating plans will merit scrutiny. A key research issue will also be the impact and consequences of internet shutdowns, frequently resorted to by countries. Digital money, too, assumes importance in crisis situations and research will address their adoption, consequences, and mode. Aspects of surveillance and privacy gain importance with increased digital usage.  相似文献   

顺应与重塑:我国校园体操发展的生态适应与主动转型     

陶成武  李先雄 《武汉体育学院学报》2020,54(12):82-88

新中国成立以来我国校园体操发展的价值理念、存在样态与治理实践发生了重大变革与结构转型。价值理念从工具理性的健康诉求上升到了价值理性的生命育化,践行了从强体卫国到重技荣国,身心之育到生命之育的目标转向与效用升级,内蕴有对学校体育崇高使命与体操事业发展的不懈追求。存在样态践履了技术传承到活动育人的过程延伸,既有前期继承发展到本土创新的结构异化,亦有期待从内容分散到系统规划的量质协调发展,大致表现为外部引入为拓展,本土适应为创新的总体特征。治理实践历经了高度集权的行政依附到参与分权的责能转移,推动了治理主体由“同构”多元向“自主”多元的关系转变。长远来看,我国校园体操的发展要走出狭隘理论认知与实践表达的误区,基于对个体健康成长与全面发展的理念,系统规划校园体操的学—练—赛,以及平衡治理主体之间的契约合作关系,以推动校园大众性体操之扩基与竞技性体操之强基的量质协调与融合发展。  相似文献
