Chinese city growth has transitioned recently. Urban regeneration that fits local conditions has replaced rapid urbanization. City modernization and historic preservation often clash. Qingdao's ancient blocks need preservation and utilization to develop responsibly. This article aims to investigate the design interventions of adaptive reuse using in practical preserved projects. The study intends to give relevant participants interventions to consider while renovating historic districts to make theories, concepts, and plans guide, promote, and constrain the practice. It should also offer practical solutions to historic city renovation issues.
A growing body of literature suggests that the world's languages can be classified into three rhythm classes: mora-timed languages, stress-timed languages, and syllable-timed languages. However, scholars cannot agree on which rhythmic measures discriminate rhythm classes most satisfactorily and whether the speech rate factor should be considered. In this study, we analyze speech production by bilingual speakers, and compare their production with that of monolingual speakers and ESL speakers. Our rhythmic metric measure results show that when speech rate is taken into consideration, a combination of the two metric measures for vowels, Varco∆V and vocalic nPVI, is most reliable in discriminating different rhythm classes, while consonants do not seem effective, whether the speech rate factor is included or not.
