In Snow White,Donald Barthelme subversively rewrites the Grimm’s fairy tale“Snow White”with a postmodern *** significant adaptation is the parody of the wicked stepmother-figure into Jane-a semi-witch who bemoans the passing of her youth and tries to keep the love of the opposite sex *** as the female antagonist with her caddish lover Hogo forms a romantic relationship which constructs a main conflict in the novel,and their romance works like a distorting mirror,dramatically reflecting the states of American in the *** paper is intended to interpret Jane and Hogo’s romantic relationship by profiling Jane and Hogo in romance,analyzing the conflicts between their mating strategies and Jane’s consequent sexual jealousy from the perspective of Literary *** the analysis,the carnalism,individualism,and the unbroken gender shackle depicted in the novel are revealed and criticized,facilitating the understanding of human nature and Barthelme’s attitude towards the postmodern world.

Single metal atoms anchored on nitrogen-doped carbon materials(M-N_(4))have been identified as effective active sites for catalyzing the two-electron oxygen reduction reaction(2e-ORR).However,the relationship between the local atomic/electronic environments of the M-N_(4) sites(metal atoms coordinated with different types of N species)and their catalytic activity for 2e-ORR has rarely been elaborated clearly,which imposes significant ambiguity for the rational design of ***,guided by the comprehensive density-functional theory calculations and predictions,a series of Zn-N_(4) single-atom catalysts(SACs)are designed with pyrrole/pyridine-N(N_(Po)/N_(Pd))synergistic coordination and prepared by controlling the pyrolysis temperature(600,700,and 800℃),Among them,the dominated Zn-N_(4) configurations with rationally combined N_(Po)/N_(Pd)coordination show~*OOH adsorption strength close to the optimal value,much superior to those with mono N ***,the as-prepared catalyst exhibits a high H_(2)O_(2) selectivity of over 90%both in neutral and alkaline environments,with a superb H_(2)O_(2) yield of up to 33.63 mol g^(-1)h^(-1)in an alkaline with flow *** importantly,a new descriptor,dz^(2)+s band center,has been proposed,which is especially feasible for predicting the activity for metal types with fully occupied s and d *** work thus presents clear guidance for the rational design of highly active SACs toward ORR and provides a complement to the d-band theory for more accurately predicting the catalytic activity of the materials.

胶州湾事件之前,中德就港口租借问题进行了长达两年的交涉。德国动用了各方人马,推进公私并进的多线外交。清政府倾向于联俄以自保,对德国的无理诉求一味机械回绝,并未足够重视。德国在所谓“和平外交”与“巴兰德—李鸿章”路线接连受挫后,武力占领港口呼声高涨,又值俾斯麦去职后大陆政策转向世界政策,对华外交日趋强硬。1897年的胶州湾事件,是这一连串交涉导向的结果。其间还留下了驻德公使许景澄主张德国武力占领港口之说,更由此揭示出德国对华新外交政策的内部博弈以及晚清驻外使馆外籍参赞僭越职权的普遍问题。

近代日本实证史学同时存在两种传统,一是兰克、伯伦汉为代表的德国正统史学;二是本土承传的清代考据学与日本古学。既往关于坪井九马三的研究着重探讨其对兰克史学的移植与运用,忽略其思想的新旧杂糅、同异交缠。坪井作为西洋史(史学科)的领军人物,与日本史(国史科)的汉学考证主义史家同声相应,同气相求。氏著《史学研究法》宗奉兰克、伯伦汉之说,但在经济史、政治史、精英人物等研究取向上,坪井皆与兰克反向而行。坪井史学具有二元论的特质,他将史学切分为纯正、应用二端,构筑实证史学的同时亦倡导历史教育服务于国民教化。他生平著述驳杂而不够深刻,却多引领时趋,是日本历史领域马克思主义、社会主义的最早绍介者。
