Clip Voice: Misogyny and the Renegotiation of a Gendered Vocal Style in Chinese Digital Discourse
Journal of Sociolinguistics, Volume 29, Issue 5, Page 348-359, November 2025.ABSTRACT The participatory culture of social media allows women's voices to be heard but also parodied and policed. On Chinese social media platforms, where performers rapidly adopt and transform vocal trends for engagement, discourse on gendered vocal styles has proliferated.

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 5, Page 624-632, May 2025.ABSTRACT Objectives Placental insufficiency contributes to many obstetric pathologies, but there is no bedside clinical tool to evaluate placental perfusion. We have developed a method to acquire multiple three‐dimensional (3D) power Doppler (PD) ultrasound (US) volumes of placental vasculature, with infrared camera tracking of the precise spatial ...

Journal of Linguistic Anthropology, Volume 34, Issue 3, Page 441-469, December 2024.Abstract This paper develops the concept of “indexical deprivation” from the experiences of English learning in relation to cochlear implant use among Taiwanese deaf adults. Based on the framework of language ideological assemblage, this paper traces how institutional discourses and practices at different levels contribute to the indexicalization ...

Methods in Ecology and Evolution, Volume 15, Issue 11, Page 1926-1939, November 2024.Abstract Simulation studies are essential tools to assess statistical methods. Functioning as controlled experiments, simulations generate data from known underlying processes. However, unclear or incomplete reporting of simulation studies can impact their interpretability and reproducibility, potentially leading to the misuse of statistical methods ...
