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.

New Phytologist, Volume 248, Issue 2, Page 690-705, October 2025.Summary Abscisic acid (ABA) induces stomatal closure, reducing transpirational water loss, a critical adaptation for agriculture under drought. However, ABA is often viewed cautiously as stomatal closure limits CO2 uptake for photosynthesis and growth.

Infrastructure and Poverty Traps
Poverty &Public Policy, Volume 17, Issue 3, September 2025.ABSTRACT This paper investigates whether infrastructure development helps poor economies escape low‐income traps or transition to higher‐income levels. Infrastructure has always been central to development policies and is critical for achieving the SDGs.

Veterinary Dermatology, Volume 36, Issue 3, Page 302-313, June 2025.Background – Malassezia pachydermatis (MP) is implicated in severe dermatitis and otitis externa (OE) of companion animals and recently gained attention for its increasing resistance to azole compounds. For this reason, developing novel therapeutic strategies is of great interest. In a previous work, we used reference yeast isolates to evaluate several
