Fire severity shapes asynchronous herbaceous and shrub recovery along contrasting soil-recovery pathways in a subtropical Pinus massoniana plantation
Post-fire ecosystem recovery depends on both fire severity and the coupling between soil and vegetation processes, yet herbaceous and shrub layers may follow different recovery pathways. We examined how fire severity shaped surface-soil recovery and understory vegetation dynamics in a subtropical Pinus massoniana plantation in Daye, central China. Unburned reference, low-severity, moderate-severity, and high-severity plots were surveyed at 0.5, 1…
Critical Ethnography
Critical ethnography interrogates dominance and resistance as they manifest in everyday cultural, social, and political practice. Since its debut in the 1970s, critical ethnography has been widely practiced in anthropology, sociology, and applied social research disciplines such as education, public health, and psychology. The idea of “critical” does not mean to judge social phenomena based on unjustified personal preferences but to interpret and…

Depicting urban multi-scale tourist activity spaces using digital footprints for smart destinations
Given the complex characteristics of city structure, the analysis of tourists’ activities in urban space is challenging. Previous studies on urban tourists’ activities were mostly limited to official administrative units, such as attractions, blocks, and administrative districts, and rarely considered the multi-scale characteristics of urban tourism space. This study offered insights into urban tourism by depicting multi-scale tourism spaces from…
Digital Worlds and Our Folding Realities
In this article, we think with the ongoing conversations on “embracing digital worlds” through juxtaposing the methodological practices enabled by “digital worlds” with the writings of science fiction. Specifically, we leverage the criticality of a Chinese sci-fi text, Folding Beijing, to shed light on issues of equity and justice in qualitative inquiry. This approach allows us to interrogate, problematize, and trespass the boundaries of the digi…
