The Stability

Raphanus sativus, an important cruciferous vegetable, has been increasingly affected by clubroot disease. Establishing a stable and accurate resistance identification method for screening resistant germplasms is urgently needed in radish. In this study, the influence of inoculum concentration, inoculation methods, and pH of the substrate on disease occurrence was studied. The result showed that the disease index (DI) was highest at 2 × 108 spores/mL, the efficiency of two-stage combined inoculation methods was higher than others, and pH 6.5 was favorable for the infection of P. brassicae. By using this new method, DIs of 349 radish germplasms varying from 0.00 to 97.04, presented significantly different levels of resistance. Analysis showed that 85.06% germplasms from China were susceptible to P. brassicae, whilst 28 accessions were resistant and mainly distributed in east, southwest, northwest, and south-central China. Most of the exotic germplasms were resistant. Repeated experiments verified the stability and reliability of the method and the identity of germplasm resistance. In total, 13 immune, 5 highly resistant and 21 resistant radish accessions were identified. This study provides an original clubroot-tolerance evaluation technology and valuable materials for the development of broad-spectrum resistant varieties for sustainable clubroot management in radish and other cruciferous crops.

Abstract. The annual temperature anomalies in South Central China from 1850 to 2008 were reconstructed by synthesizing three types of proxies: the spring phenodate of plants recorded in historical personal diaries and observations; the snowfall days extracted from historical archives and observed at meteorological stations; and five tree-ring width chronologies. The instrumental observation data and the leave-one-out method were used for calibration and validation. The results show that the temperature series in South Central China exhibits inter-annual and decadal fluctuations since 1850 (e.g., quasi-15 years and quasi-35 years fluctuations). The first three cold decades were the 1860s, 1890s and 1950s, while 1893 was the coldest year. Except that the three warm decades occurred around the 1850s, 1870s and 1960s, recent warm decades from the 1990s to the 2000s represent unprecedented warming since 1850.

China, like the United States, has no defined concept of privacy in its Constitution and Chinese citizens have to work out how to negotiate their presence online, just as others elsewhere do. Online privacy in China has not received strong legislative protection compared with the U.S. and European countries as privacy has never written as an individual right in China’s Constitution, nor in the Civil Law. Chinese privacy perceptions and everyday privacy practices in social media have not been fully examined. This article presents an original, ethnographic study of how 26 Chinese youth, men and women, and 25 older rural women from Changsha, south-central China are negotiating what counts as privacy online in their everyday practices. It finds out that youth group in Changsha has a stronger understanding of the technical level of deployment of the social media technologies, enacting both positive and protective self-presentation instantiated by “human flesh search,” “public online privacy,” and “improved firewall.” However, the notion of shameful secrets touches on the protection of the reputation of those concerned, and social relationships play an important role in privacy boundary negotiation, common to both groups. This demonstrates that sociocultural contexts need to be taken into consideration and should be more nuancedly examined when studying online privacy and working out privacy protection methods.

Abstract Rates of biodiversity loss in Southeast Asia are among the highest in the world, and the Indo-Burma and South-Central China Biodiversity Hotspots rank among the world’s most threatened. Developing robust multi-species conservation models is critical for stemming biodiversity loss both here and globally. We used a large and geographically extensive remote-camera survey and multi-scale, multivariate optimization species distribution modelling to investigate the factors driving biodiversity across these two adjoining biodiversity hotspots. Four major findings emerged from the work. (i) We identified clear spatial patterns of species richness, with two main biodiverse centres in the Thai-Malay Peninsula and in the mountainous region of Southwest China. (ii) Carnivores in particular, and large ungulates to a lesser degree, were the strongest indicators of species richness. (iii) Climate had the largest effect on biodiversity, followed by protected status and human footprint. (iv) Gap analysis between the biodiversity model and the current system of protected areas revealed that the majority of areas supporting the highest predicted biodiversity are not protected. Our results highlighted several key locations that should be prioritized for expanding the protected area network to maximize conservation effectiveness. We demonstrated the importance of switching from single-species to multi-species approaches to highlight areas of high priority for biodiversity conservation. In addition, since these areas mostly occur over multiple countries, we also advocate for a paradigmatic focus on transboundary conservation planning.

Purpose This paper aims to investigate the situation and evolution of sustainability performance in China. Design/methodology/approach This paper adopts the global Malmquist-Luenberger (GML) productivity index based on data envelopment analysis and Tobit regression for analysis. Findings The results indicate the following: China’s sustainability performance has been improving since 2005 and is closely related to the national development strategy and supportive policy; regional gaps in sustainability are a prominent problem represented by the fact that South Central China is becoming a sustainability collapse zone; interprovincial heterogeneity is evident with the varying development speed and conditions; and the level of sustainability performance has a significantly positive correlation with the urbanization rate, investment completed in the treatment of industrial pollution, government appropriation for education and per capita area of paved roads, but it has a negative correlation with the possession of private vehicles. Originality/value As an application, this study assessing the GML productivity index of 30 provinces in China from 2005 to 2015 and analyse the sustainability performance on three regional levels (i.e. country level, regional level and provincial level). Tobit regression is also applied to recognize the factors related to the GML index with the results taken as references for policy suggestions. The results have implications for a comprehensive understanding of China's sustainability performance and policymaking in this field.
