Zhida: blockchain potential in household waste recycling
No full textIn 2020, the chief executive officer of Zhida Environmental Technology, a waste management company based in Nanjing, China, was considering adopting blockchain technology into the company's work process. With the concept of Internet plus recycling, the company was committed to waste sorting and had introduced innovative household waste solutions. However, new challenges were emerging, including stagnant resident participation rates, low profit returns, competitor expansion, and limited support from the local government. Inherent blockchain technology functions such as digital token services, a transparent recycling chain, and collaborative governance mechanisms could potentially improve the company's current operations and provide a first mover position in the market. However,the chief executive officer had to thoroughly consider the decision of adopting blockchain technology: What true value could it offer and what potential challenges could arise
Remote estimation of chlorophyll a concentrations over a wide range of optical conditions based on water classification from VIIRS observations
No full textThe accurate estimate of surface chlorophyll a concentrations (Chla) by remote sensing presents a number of challenges where inherent and apparent optical properties have significant spatial or temporal variability. Indeed, Chla algorithms for Case 2 waters are often lake or region specific, and they are usually highly sensitive to changes in the dominant chromophoric constituents. This study develops and validates an absorption-specific approach to estimating Chla across an optically heterogeneous dataset. The approach is based on the classification of the optically dominant constituent. We tested this approach with in situ data from Taihu Lake, Poyang Lake, Chaohu Lake, Shitoukoumen Reservoir, Pearl River Estuary and Daya Bay as well as using HydroLight simulated data. The results show an improved performance when compared to most single Chla algorithms. We validated the approach with data from the Visible Infrared Imager Radiometer Suite (VIIRS). Results showed that this absorption-specific approach provided good Chla estimates over clear to very turbid waters with a wide range of optical conditions (R-2 = 0.76, r(RMSE) = 35%, n = 230, p < 0.01)
An absorption-specific approach to examining dynamics of particulate organic carbon from VIIRS observations in inland and coastal waters
No full textAn absorption-based approach was used to determine surface particulate organic carbon (POC) concentrations in both inland and coastal waters. The improved performance of this approach was based on the specification of local POC absorption characteristics based on dominant POC sources; phytoplankton or detritus based. This specification was made using a new POC-Index (PI), developed and tested across a range of POC (300-10,000 mg/m(3)) conditions in temporally and spatially heterogeneous inland and coastal waterbodies. The POC model was based on remote sensing reflectance (R-rs, sr(-1)) in four wavebands: R-rs(751), R-rs(488) and R-rs(R/G), where R is the red band [R-rs(672)] for detritus dominated waters and G is the green band [R-rs(555)] in the phytoplankton dominated waters. The model provided a high R-2 (0.74) and relatively low r(RMSE) (42.0%, N = 136, p < 0.01). Validation with independent datasets from Chaohu Lake and the Yangtze River Estuary produced a larger positive bias (R-2 = 0.59, r(RMSE) = 83%, delta = 634 mg/m(3), S = 0.63, I = 1439 mg/m(3)); nevertheless, the bias was reduced when tuned with local data (R-2 = 0.80, r(RMSE) = 45%, delta = 72 mg/m(3), S = 0.81, I = 327 mg/m(3)). Additionally, HydroLight simulations presented an independent correlation between PI and CDOM conditions and reasonable POC estimates from the new approach developed in this study. The approach was tested using data from Visible Infrared Imaging Radiometer Suite (VIIRS) in a range of optically complex conditions to quantify carbon dynamics. We indicate the advantages and challenges of using this approach in ecosystems where multiple organic carbon sources are present

Inventing A Wolfish China - On Jiang Rong'S Wolf Totem
No full textThe Wolf Totem by Jiang Rong has won great success both in and out of China. Jiang Rong criticizes Han Chinese and embraces the culture of the northern ethnic minority group, the Mongols, because of its stronger sense of competition and domination. In the epilogue of this novel, Jiang argues that the wolf totem was the most ancient totem for all Chinese people and retells Chinese history using this framework. This paper explores the background of the novel and its author, as well as supporting materials the author uses in his proposal concerning the wolf totem, and suggests that the wolf totem is a purely ideological invention of Jiang Rong. This invention reflects Jiang's own philosophy and caters to the cultural needs of modern Chinese people. In inventing the wolf totem, the author uses historical documents, archeological findings, as well as a far-fetched bodily metaphor. However, none of this evidence is validated by scholarly research
Interviews with Yang Jiang
No full textYang Jiang was born, under her real name of Yang Jikang, in 1911. She is the author of a novel, several plays, and a large number of sanwen. Her first writing dates back to 1933, and her latest work, Women sa (We Three), in which she recalls family memories, appeared in July 2003, and has been highly successful, with 180,000 copies sold within two months. However, for thirty years, from 1949 to 1981, for obvious reasons, Yang Jiang preferred to devote herself entirely to teaching, research—she is also an expert on Chinese and foreign literature—, and translation: she is the translator, most notably, of the Chinese version of Don Quixote. She is now devoting herself to the publication of the work of her husband, the scholar Qian Zhongshu (1910-1998). In France she is best known for her narratives of the Cultural Revolution, published by Christian Bourgois.The two interviews that follow were carried out in 2005. Yang Jiang gave written answers to the questions I had sent her, which explains the slightly abrupt nature of our exchanges, given that it was not possible for me, by the nature of the interviews, to respond spontaneously to her words. If we seem to jump from one subject to another, it is because I had asked her to clarify certain details that I planned to use in my research into her work (« La Figure de l’intellectuel chez Yang Jiang » [“The Intellectual in The Work of Yang Jiang”], which became my doctoral thesis in Chinese Studies, under the direction of Isabelle Rabut, Inalco, Paris, December 2005, 404 pp.). Yet, to me, these words of Yang Jiang are of interest just as they are, since she uses words so sparingly and generally refuses to do interviews. In any case, and I am grateful to her for this, she only allowed these words to be published precisely because she had written them herself
Jiang Rong, Le Totem du loup, (Wolf Totem) translated by Yan Hansheng and Lisa Carducci
No full textPublished in China in 2004 by Changjiang wenyi chubanshe, Jiang Rong’s novel Lang tuteng (Wolf Totem) was immediately a phenomenal success. I myself witnessed this success while in China, where bookshops displayed multiple stacks of the book. Its author, Jiang Rong, the pseudonym of Lu Jiamin, was an activist in the Tiananmen Square movement in 1989; now a researcher in social sciences and the husband of Zhang Kangkang, a well-known writer, Jiang Rong maintained a mystery surrounding his iden..
