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 In inventing the wolf totem, the author uses historical documents, archeological findings, as well as a far-fetched bodily metaphor.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
On Sharpe-ratio-based Optimal Insurance Design
No full textAs an important risk-hedging tool, insurance can increase an individual’s expected utility or reduce her risk exposure. However, pursuing both goals is rarely considered in the literature of insurance contracting. This thesis delves into the optimal insurance design problem by striking a balance between the expected utility and the associated risk. To tackle this objective, we resort to the notion of the Sharpe ratio to identify the optimal contract, which is located on the efficient frontier. The focus of this thesis centers on utilizing Value at Risk (VaR) and Tail Value at Risk (TVaR) as risk measures. We derive parametric forms of the optimal indemnity function in scenarios where a decision maker (DM) seeks to maximize end-of-period expected utility subject to a pre-set acceptable risk level. Since the closed-form or analytical solution for such a contract is rather difficult to derive, we present numerous numerical examples to comprehensively explore various aspects of this methodology. As shown by the results, the Shapre-ratio-based contract is relatively robust except in the Pareto case under VaR preference, and increasing the probability level or risk loading factor adversely affects the ratio. Furthermore, we numerically analyze the popular industrial contract specifically the limited excess-of-loss contract, under the framework of VaR. Our findings reveal that the optimal policy is achieved when the upper limit coverage equals VaR minus the deductible amount. This finding bears a strong resemblance to the optimal contract in our proposed model. The results complement the study of Jiang and Ren (2021)
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
The function and clinical implication of YTHDF1 in the human system development and cancer
No full textYTHDF1 is a well-characterized m6A reader protein that is essential for protein translation, stem cell self-renewal, and embryonic development. YTHDF1 regulates target gene expression by diverse molecular mechanisms, such as promoting protein translation or modulating the stability of mRNA. The cellular levels of YTHDF1 are precisely regulated by a complicated transcriptional, post-transcriptional, and post-translational network. Very solid evidence supports the pivotal role of YTHDF1 in embryonic development and human cancer progression. In this review, we discuss how YTHDF1 influences both the physiological and pathological biology of the central nervous, reproductive and immune systems. Therefore we focus on some relevant aspects of the regulatory role played by YTHDF1 as gene expression, complex cell networking: stem cell self-renewal, embryonic development, and human cancers progression. We propose that YTHDF1 is a promising future cancer biomarker for detection, progression, and prognosis. Targeting YTHDF1 holds therapeutic potential, as the overexpression of YTHDF1 is associated with tumor resistance to chemotherapy and immunotherapy
An Unusual and Facile Synthetic Route to Alumoles
No full textAbstract Reaction of the aluminum dialkynyl LAl(CCR)2 (L=N,N‐chelate ligand and R=organic group) with B(C6F5)3 proceeds through an intermediate with Al⋅⋅⋅η2‐C≡C side‐on coordination to form the alumoles (2, 4, 6). A distinctive reaction pattern indicates a new facile synthetic route to aluminum‐containing heterocycles. The synthetic process is described, and the characterization of compounds and computational calculations were carried out. Furthermore, alumoles 2 and 4 exhibit an aggregation‐induced emission (AIE) of the bright yellow fluorescence.Al in: Reaction of the aluminum dialkynyl with B(C6F5)3 proceeds through an intermediate with Al⋅⋅⋅η2‐C≡C side‐on coordination to form the alumole.

Efficient Tuning of Surface Nickel Species of the Ni-Phyllosilicate Catalyst for the Hydrogenation of Maleic Anhydride
No full textThe
rational design of catalyst is vital in the hydrogenation of
maleic anhydride (MA) to chemicals, for its special construction with
one CC bond and two CO bonds. Herein, the catalyst
with nickel nanoparticles (NPs), inlaid nickel phyllosilicate (Ni-PS)
featured with proper Ni0 and assembled Lewis acid sites,
is proposed for the efficient hydrogenation of MA to succinic anhydride
(SA) and γ-butyrolactone (GBL). The remarkable efficiency is
attributed to the synergistic effect between the surface Ni0 and the Lewis acid sites induced from partially reduced Ni and coordinatively
unsaturated Ni(II) in Ni-PS. The acid sites adsorb and activate the
CC and CO groups, whereas the Ni0 facilitates
the H2 decomposition. In situ XPS demonstrated that the
ratio of surface Ni0 and Lewis acid sites can be modulated
effectively by changing the Ni/Si molar ratio in the catalysts, and
they exhibited significantly different catalytic activity in the hydrogenation
of MA. Under a lower temperature, the hydrogenation activity of MA
to SA linearly increases by increasing the Lewis acid sites surface
area when the accessible Ni0 surface area is enough, whereas
it is primarily affected by the Ni0 sites under high temperature
for the hydrogenation of MA to GBL
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..
