摘要：叙述的生成和传达是叙述者独有的底线功能。在叙述生成时,各要素的选择与组合依据的是已有的文化程式、规定和媒介属性。这些程式、规定和媒介构成叙述文本的框架,叙述者也随之形成。此阶段的叙述者为“框架叙述者”。在传达叙述时,传达意向使叙述者呈现出不同程度的人格化,人格化因此也作为叙述者在叙述文本中显身的方式,此阶段的叙述者为“人格化叙述者”。“框架—人格”叙述者观全面把握了叙述者的功能和形态。受述者作为叙述者传达的对象而存在。依据叙述者人格化程度可以得出叙述者向受述者传达叙述的两种基本方式。

摘要：智能网联汽车的快速发展为道路基础设施服役性能的监测提供了更加便捷、高效的全新解决方案。为发挥智能网联车辆优势,提高车载响应类路面平整度检测的便捷性和准确性,首先提出了一种基于车辆振动响应信号的路面纵断面高程反演及平整度估计方法,该方法通过对车辆垂向动力学的合理建模及模型参数辨识,以车身振动响应信号作为测量值,借助增广卡尔曼滤波算法,对路面断面高程进行反演估计,进而求解国际平整度指数。随后,采用高斯过程模型对多车估计结果进行拟合以实现多车结果的融合解析。考虑到智能网联汽车可实现车车互联通信的优势,进一步将前车融合结果纳入当前车辆估计算法,并将其作为伪测量量,实现多车协同估计以提高当前车辆估计结果的准确性。借助数值仿真及实测数据对前述方法进行验证,实测结果表明:所提出的单车估计方法所得国际平整度指数的估计值与实测值相关性可达87%,均方根误差约为0.26 m·km-1;多部车辆的重复性测试验证了该方法的准确性和可重复性;多车结果融合及协同估计策略不仅可降低单车估计结果的误差,且可在一定程度上提高单车估计算法的稳定性。在算法验证基础上,设计了一套可实现路面平整度在线评估的原型系统,并提出了智能网联环境下路面平整度评估框架,进而对该系统及框架进行了离线验证。基于该框架,不仅可实现路面平整度的单车在线估计,还可对多车感知结果进行融合,并将平台端融合结果用于终端计算中,实现云-端协同估计,从而提高终端反演的准确性和鲁棒性。

摘要：笔墨体验贯穿于我的创作与生活之中,作为一种切实而复杂的个人感悟方式,历经风格的追索、生活的融冶、传统的体悟以及笔墨表现的探究而衍生出自身纯正的探索指向。将一系列以精致意味为要求的笔墨体验嵌入创作题材中,品味一线一墨、一皴一点所构筑的自然秩序和画理结构,梳理和整合自身在生活和创作中思绪与言说方式的细微变化,从中抽绎出具体真切的感悟点滴,以作整体而系统性的理性观照,将有益于探寻自身与绘画之间不断磨合与嬗变的微妙关系。以此为切入口,或许能触至自身笔墨语言探索过程中的精微处,对自身创作实践中笔墨语言追求产生切实深切的意义。

摘要：为寻找和解读学术期刊出版改革的各种现实阻力,文章通过对比农村联产承包责任制改革、国有企业改革和学术期刊出版改革,分析学术期刊出版改革迟滞不前的主要原因,揭示学术环境对学术期刊出版改革形成约束的内在逻辑和改革的可能路径。

摘要：学术期刊数字出版治理的制度安排都难免具有局限性,而且只能规定出版行为底线,无法强制出版主体拥有崇高的价值追求。出版伦理的建构能够推动学术期刊数字出版行业的健康有序发展,缓解学术期刊数字出版与传统出版之间的矛盾。文章分析了学术共同体的出版伦理认知对学术期刊数字出版的影响,阐述了传统学术期刊出版者和学术期刊数字出版者的出版伦理建构路径,最后提出应建构学术期刊数字出版利益相关者协同治理的出版伦理共识。

摘要：学术期刊数字出版具有传统出版无法比拟的优势,它在为人们带来高效和便捷的同时,也对人的思想创新、主体能力、主体性空间构成了威胁;并且学术期刊数字出版的技术特性也容易导致市场垄断继而抑制创新。学术期刊数字出版的这些行为特征,迫切要求反思与规制其价值判断取向和改革路径取向。从学术期刊数字出版的改革取向来看,应该通过反垄断规制来抑制现有的学术期刊数字出版平台规模过于膨胀,同时出台扶持潜在进入者的政策,鼓励多元化的创新,包括多样化的数字出版技术模式和商业模式、开放获取出版模式、基于行业的聚合模式、基于地域的聚合模式、专业搜索附加链接模式、引文与索引附加链接模式等。

摘要：最新颁布的《义务教育艺术课程标准(2022年版)》再次强调了“坚持以美育人”和“审美感知”在音乐教育中的重要作用。文章首先解读了“以审美为核心”这一概念,随后论述了中小学音乐教育中“以审美为核心”理念的四个价值:内化于心,辐射带动;融合“以创造力为核心”的音乐教育理念;改变“美育”附属于“德育”“智育”的局面,突出音乐的本体价值;指向全面育人目标的实现。然后从音乐教学法、音乐表演教学、创造力发展三个角度论述了“以审美为核心”的理念在中小学音乐教学实践中的体现,并且提出了该理念在新时代的发展愿景。
