Investment in science, technologies, and infrastructures has been a critical aspect of China’s development strategy since the early 2000s. China’s national policies designated waste-to-energy (WtE) incinerators as the dominant end-of-life technology to bring about a form of modern and sustainable waste treatment that can turn waste into energy while eliminating pollution. Amid rising citizen skepticism over the safety and efficacy of this technology in China and elsewhere, this article examines the genre of the orchestrated waste tour, which seeks to place the public as witnesses to state performances of technological improvement. Tours to waste facilities illuminate the generic conventions and strategies that China’s late-socialist mode of green techno-scientific governance relied on to legitimize its achievement of environmental improvement. Tours did not produce passive observers. Through an in-depth discussion of a waste tour in Guangzhou, this paper documents that opportunities for firsthand encounters of WtE incinerators provided a forum for those suspicious of the state’s claims of techno-science to form counternarratives.

Current work in language models (LMs) helps us speed up or even skip thinking by accelerating and automating cognitive work. But can LMs help us with critical thinking -- thinking in deeper, more reflective ways which challenge assumptions, clarify ideas, and engineer new concepts? We treat philosophy as a case study in critical thinking, and interview 21 professional philosophers about how they engage in critical thinking and on their experiences with LMs. We find that philosophers do not find LMs to be useful because they lack a sense of selfhood (memory, beliefs, consistency) and initiative (curiosity, proactivity). We propose the selfhood-initiative model for critical thinking tools to characterize this gap. Using the model, we formulate three roles LMs could play as critical thinking tools: the Interlocutor, the Monitor, and the Respondent. We hope that our work inspires LM researchers to further develop LMs as critical thinking tools and philosophers and other 'critical thinkers' to imagine intellectually substantive uses of LMs.

However, its downstream molecular events are poorly understood. Here, we identify a NAC transcription factor, ZmNAC84, in maize, which physically interacts with ZmCCaMK in vitro and in vivo. ZmNAC84 displays a partially overlapping expression pattern with ZmCCaMK after ABA treatment, and H2O2 is required for ABA-induced ZmNAC84expression. Functional analysis reveals that ZmNAC84 is essential for ABA-induced antioxidant defense in a ZmCCaMK-dependent manner. Furthermore, ZmCCaMK directly phosphorylates Ser-113 of ZmNAC84 in vitro, and Ser-113 is essential for the ABA-induced stimulation of antioxidant defense by ZmCCaMK. Moreover, overexpression of ZmNAC84 in tobacco can improve drought tolerance and alleviate drought-induced oxidative damage of transgenic plants. These results define a mechanism for ZmCCaMK function in ABA-induced antioxidant defense, where ABA-produced H2O2 first induces expression of ZmCCaMK and ZmNAC84 and activates ZmCCaMK. Subsequently, the activated ZmCCaMK phosphorylates ZmNAC84 at Ser-113, thereby inducing antioxidant defense by activating downstream genes.
