Based on thirty years of archival and documentary research and numerous field trips to the region, Joseph W. Esherick's book examines the origins of the Communist revolution in Northwest China, from the political, social, and demographic changes of the Qing dynasty (1644–1911), to the intellectual ferment of the early Republic, the guerrilla movement of the 1930s, and the replacement of the local revolutionary leadership after Mao and the Center arrived in 1935. In Accidental Holy Land, Esherick compels us to consider the Chinese Revolution not as some inevitable peasant response to poverty and oppression, but as the contingent product of local, national, and international events in a constantly changing milieu.

This article examines how artists have engaged with the issue of air pollution in Beijing, where poor air quality has become a serious public health matter. Artists have utilized various mediums including performance art, photography, and painting to represent smog. Through generating media and online attention this work has contributed to a relatively vibrant "green public sphere" (Yang and Calhoun, 2007) of air pollution discourse. In contrast to much resistance in China that relies upon making specific claims to government officials, artistic expression bypasses the authorities and appeals instead to public opinion. Artists utilize ambiguity to portray air pollution in novel ways that subtly question the structures that produce and sustain it. In this way, artists can challenge popular perceptions of smog and raise public awareness, thus intensifying support for policies that tackle smog. Yet art can also embody deep frustration at the powerlessness that artists, and the public more widely, experience when confronted by severe air pollution. Art therefore serves both as a form of activism and as an expression of curtailed agency in a politically restrictive environment.

This study provides new knowledge on the mobility, behavior, and partitioning of 17 perfluoroalkyl substances (PFASs) in the water-sediment-plant system along the Dongzhulong and Xiaoqing Rivers. The fate of PFASs in these rivers is also discussed. The study area is affected by the industrial production of perfluorooctanoic acid (PFOA). The ∑PFASs in water and sediments close to the industrial discharge were 84,000 ± 2000 ng/L and 2300 ± 200 ng/g dw, respectively, with the concentrations decreasing along the river due to dilution. PFOA was the dominant compound (74–97% of the ∑PFASs), although other PFASs were identified close to urban areas. Principal component analysis and solid-liquid distribution coefficients revealed that long-chain PFASs accumulated in the sediment whereas short-chain PFASs remained in the water all along the river. PFASs were taken up by plants and remobilized to different plant compartments according to shoot concentration factors (SCFs), root concentration factors (RCF), and transfer factors (TFs). Among the four plant species studied, floating plants absorbed high levels of PFASs, while rooted species translocated short-chain PFASs from the roots to the shoots. Therefore, floating species, due to their high uptake capacity and large proliferation rate, could eventually be used for phytoremediation. ; Pere Colomer Vidal acknowledges the funding from the European Union Europe Aid 'SEW-REAP' project [ECRIP ICI+/2014/348–010].
