摘要：The controversy over the partial demolishment of the Nangang Bottle Cap Factory for redevelopment is a prime example of the ongoing public debate about urban renewal in Taipei. The controversy crystalizes the tension between a growing public desire for historical preservation in Taipei to safeguard shared history and restore collective memory, and profit-driven capitalistic development. The transformation of the factory over the past decade--from disused public property to a city-operated Urban Regeneration Station for fostering art and innovation, and finally to a demolition site that is being readied for new construction--illustrates the tug of war between the exigencies of cultural/historical preservation and urban renewal in Taipei. During the process, not only did citizen activists play a maior role in raising the public＇s awareness of the unique value of the Nangang Bottle Cap Factory as one of the last major relics of Taipei＇s industrial heritage, graffiti artists also created works in the abandoned factory that dialogued about its contested future under a neoliberal capitalist regime. By tracing the origins of the controversy, I argue, through a photo documentation of the accumulated graffiti inside the factory before demolition began, that the factory ＂ruin＂ has functioned as a theater for diverse forms of guerrilla urbanism, including engaged art, urban exploration, and community organization.

摘要：本文描述SpeakGoodChinese(SGC)这一语音识别和视觉化技术如何帮助学生习得汉语声调。SGC可以通过识别分析学生的发音并提供视觉上的反馈来辅助学生掌握声调。本文也讨论如何将SGC有效融入美国本科汉语初级阶段教学。研究以2014-2016年间学生所制视频文件为样本计算声调发音准确率。语料的量化分析及教学策略的质性分析都指向语音视觉化技术对声调习得的积极作用。研究发现,将SGC与严格评估结合能促进学生独立练习并促使老师通过频繁实时纠错改善学生的发音。
