摘要：麦克卢汉把广告和流行文化产品称为“工业人的民俗”,认为它们是新媒介技术的产物。新媒介技术及其产品既构成了新的媒介环境,又在潜意识层面上塑造了民众的感知模式。为了唤醒民众,使其摆脱被新媒介技术蛊惑与奴役的困境,麦克卢汉借助先锋艺术的方法,试图以此来揭示新媒介技术的运作机制,达到社会集体救赎的目的。从历史的角度来看,麦克卢汉的艺术观与民俗观,与其媒介环境观一样,具有重要的理论启迪与借鉴意义。

摘要：从广告教育的视角出发,结合近年来的教学经验和学生反馈,发现在线广告教育正面临三重挑战与机遇。师生互动体验差与广告实操效果差、广告创意应用软件版权问题等挑战不利于在线广告教育质量的提升。研究认为,在线广告教育发展的机遇在于其开放性和灵活性、教学资源的数字化及其拓宽了广告“教师”和“学生”的外延。

摘要：数字创意产业已成为推动国民经济转型升级的五大战略性新兴产业之一,也是推动“文化强国”“网络强国”建设的重要抓手。“十三五”以来,我国数字创意产业取得了跨越式发展,涌现出许多质量上乘、体现中国优秀文化的数字创意精品,而这些成就的取得离不开一个层次鲜明、结构合理、功能多样的产业政策群。为了更好地运用产业政策助推数字创意产业发展,通过深入研究“十三五”以来数字创意产业政策的演化趋势与重点领域,发现数字创意产业政策呈现出政策数量逐渐增加、政策法律效力依然较低、政策主体协同合作趋势增强、政策主题实现多元化分布、政策工具使用不均衡等整体性特征。数字创意产业政策的重点也集中在技术赋能产业发展、先进文化引领产品和服务、构建完善的产业生态体系和营造良好制度环境等方面。未来一段时期,数字创意产业政策的制定还需要围绕这些重点领域,进一步完善政策群结构,优化政策工具组合,提高政策主体间协同合作、推动制度型开放,以此推进数字创意产业结构进一步跃升,实现数字创意产业整体性高质量发展。

摘要：通过对胶东半岛即墨、莱西等地面磕子历史与现状的考察,结合胶东民间艺术在造型、审美和工艺方面的互通性,综合其社会内容的扩充、工艺的融汇及构图审美的拓展,能够发现面磕子视觉图案呈现的一个重要特点和隐形逻辑:多方面的逻辑集成性,包括图案知识集成性、工艺集成性、构图集成性,其视觉特征带有明显的从创作自发性到意识集成性的转变历程。通过胶东面磕子图案的艺术转化和语义解读,梳理文化符号的传承脉络,建设文化基因库,可以为传统面磕子与现代视觉设计相结合提供思路。

摘要：When a curling rock slides on an ice sheet with an initial rotation,a lateral movement occurs,which is known as the curling *** force of friction between the curling rock and the ice sheet changes continually with changes in the environment;thus,the sport of curling requires great skill and *** throwing of the curling rock is a great challenge in robot design and control,and existing curling robots usually adopt a combination scheme of a wheel chassis and gripper that differs significantly from human throwing movements.A hexapod curling robot that imitates human kicking,sliding,pushing,and curling rock rotating was designed and manufactured by our group,and completed a perfect show during the Beijing 2022 Winter Olympics *** switching between the walking and throwing tasks is realized by the robot’s morphology transformation based on leg configuration *** robot’s controlling parameters,which include the kicking velocity v_(k),pushing velocity v_(p),orientation angle θc,and rotation velocityω,are determined by aiming and sliding models according to the estimated equivalent friction coefficientμ_(equ)and ratio e of the front and back *** stable errors between the target and actual stopping points converge to 0.2 and 1.105 m in the simulations and experiments,respectively,and the error shown in the experiments is close to that of a well-trained wheelchair curling *** robot holds promise for helping ice-makers rectify ice sheet friction or assisting in athlete training.
