关键词： OBE教育理念   计算机科学与技术专业   三维一体   教学模式  

摘要： 计算机科学与技术专业是新一代信息技术产业的学科基础,为信息技术的发展提供了源源不断的人才支撑。传统的计算机科学与技术专业教学模式存在理论与实践分离、知识与应用分离等现象,对此,文章建议以OBE教育理念为核心进行教学模式改革,探索计算机科学与技术专业课程“导练评”三维一体教学模式,培养兼具高深理论知识和扎实实践能力的高素质计算机专业人才。

关键词： Decision trees  

摘要： This paper explores the current trending research areas in the field of Computer Science (CS) and investigates the factors contributing to their emergence. Leveraging a comprehensive dataset comprising papers, citations, and funding information, we employ advanced machine learning techniques, including Decision Tree and Logistic Regression models, to predict trending research areas. Our analysis reveals that the number of references cited in research papers (Reference Count) plays a pivotal role in determining trending research areas making reference counts the most relevant factor that drives trend in the CS field. Additionally, the influence of NSF grants and patents on trending topics has increased over time. The Logistic Regression model outperforms the Decision Tree model in predicting trends, exhibiting higher accuracy, precision, recall, and F1 score. By surpassing a random guess baseline, our data-driven approach demonstrates higher accuracy and efficacy in identifying trending research areas. The results offer valuable insights into the trending research areas, providing researchers and institutions with a data-driven foundation for decision-making and future research direction. © 2023, CC BY-NC-SA.

关键词： 乡村教师   留任意愿   情感能量   互动仪式   教育生活史  

摘要： 提升教师留任意愿是当前乡村教师队伍建设的难题。基于积极主义视角,采用柯林斯的互动仪式链理论,以教育生活史方法纵向、动态地挖掘乡村留任教师——T老师的心路历程,发现情感能量是支撑T老师成为“心甘情愿留任者”的内在动力,实质是乡村学校营造互动仪式的质量。提升乡村教师留任意愿需重视情感纬度,情感留人可以从改善教师人际生态、构筑成才通道等路径入手。

关键词： Infrared spectroscopy   Computer science  

摘要： In absorption spectroscopy, analysis of multicomponent gas mixtures becomes challenging when absorption features overlap (blended spectra). Here we propose a gas sensor which can accurately identify the species and retrieve the concentrations of components in a gaseous mixture in a broad spectrum. The sensor integrates a mid-infrared dual-frequency comb laser source for spectrum acquisition and a deep learning algorithm for spectral analysis. The sensor was tested on gas phase mixtures of methane, acetone and water vapor. A prototype sensor was assessed in realistic scenarios in real time. We also systematically analyzed and presented explicit visualizations to explain the underlying working mechanism of the algorithms.

摘要： 2021年,江苏省河蟹池塘养殖面积达314亩,产量37.76万吨,占全国河蟹总产量的46.72%,成为江苏渔业的支柱产业。2021年中国内地大口黑鲈养殖产量达到了70.2万吨,养殖区域遍布华南、华东、华中、西南等区域。截至2020年,江苏地区大口黑鲈精养面积约5万亩,在诸多区域实行禁养后养殖面积同比去年大幅减少,且呈持续下降趋势。然而,与其余养殖品种的套养面积(大口黑鲈与河蟹、大口黑鲈与罗氏沼虾等)却在逐年增加。

关键词： 祁门红茶文化   数字化展示   用户体验   数字活化  

摘要： 以祁门红茶文化传承和发展为出发点,分析祁门红茶文化的内涵与展示价值,探索数字信息时代祁门红茶文化展示的新途径。导入用户体验设计理念,从感官、交互、情感三个层次构建祁门红茶文化与数字技术相结合的用户体验模型,对祁门红茶文化进行数字活化设计,旨在实现其与当下社会环境的融合,提高祁门红茶文化的传播效率。

关键词： 物的社会生命   行动者网络理论   语境化   奥林匹克运动   体育文化  

摘要： 本文以奥运金牌的物质性和社会符号意义为视角,试图在“社会的社会学”和“联结的社会学”两种对立范式之间寻找交互融合的解释机制,以探讨金牌嵌入社会文化之中的行动逻辑,考察金牌与其他行动者交互所建构的社会事实。金牌在从被激活到发挥能动作用,再到语境再造的社会生命历程中,转化为一种社会生产力,促进了奥运冠军等行动者的社会阶序跃迁,激励了竞技体育从业者行为,在群体中创造了区隔与联结;金牌在礼俗社会中的嵌入,揭示了现代性背景下人情关系互动的变异趋势和价值属性,以及社会交换互动和权力运行的微观生态。随着金牌进入展陈状态,它不但促进了社会记忆的再语境化,延续了“物之活力”,而且表意了新文化空间的生成,形塑了一种社会网络体系和文化传承机制。

关键词： 公共生活   工业遗产   互动   工业转型   遗产共享   烟台  

摘要： 城市作为公共生活最活跃的地点之一,公共空间的使用感受一直以来备受关注。由于我国经济文化的迅速发展,促使公众对城市空间的高品质要求愈发强烈。城市工业遗产在保护与再利用后形成的公共空间也成为了营造城市高品质公共空间的内容之一,面对烟台工业遗产亟须保护与利用的现状以及对抗记忆遗忘和社会认同等诸多现实问题,从公共生活的视角提出了一系列转型条件和转型策略,“公共”本就是社会的共同利益,城市公共空间内的工业遗产更新是共享遗产。通过功能、文化、意识和参与的转型,达到对工业遗产的空间、文化和经济的共享,组成了某种方式的公共生活,同时为工业遗产带去了第二次生命,为烟台在后续的工业遗产保护和利用的过程中提供新的关注点,以及对公共生活与工业遗产互动的关注。
