网络治理视角下高校外语教育政策研究

中国的外语教育政策经过发展,其价值内涵不断演化,在国际交流中,外语除了具备原有工具属性,中国特色大国外交战略的实施又赋予外语新的角色定位.外语教育政策涵盖的范围不断扩大,关乎国家政治、经济与科技,单边管理的推行模式已经无法满足其治理要求.文章从网络治理的角度,分析外语教育政策利益相关者的网络构成,以人为本,以多元嵌入的协调机制、模糊边界的约束机制,提升利益主体的治理效率,达到政策的实施目标.

巴赫金边界思想渊源探究

巴赫金的边界思想与康德的二元思维模式、索绪尔的二元区分思想有着内在关联。康德、索绪尔的二元对立区分思想给巴赫金留下深刻的思想烙印,然而,巴赫金却以此为出发点,去寻找打破区分、实现沟通的可能性,探求多元共存。巴赫金民间文化思想中对边界问题的独特认识,正是建立在批判与发展康德和索绪尔的二元区分思想的基础上的。同时,作为边缘人的巴赫金所特有的边缘处境以及宗教信仰,都共同塑造了巴赫金的边界思想。

Experimental measurement of the quantum geometric tensor using coupled qubits in diamond

Geometry and topology are fundamental concepts, which underlie a wide range of fascinating physical phenomena such as topological states of matter and topological defects. In quantum mechanics, the geometry of quantum states is fully captured by the quantum geometric tensor. Using a qubit formed by an NV center in diamond, we perform the first experimental measurement of the complete quantum geometric tensor. Our approach builds on a strong connection between coherent Rabi oscillations upon parametric modulations and the quantum geometry of the underlying states. We then apply our method to a system of two interacting qubits, by exploiting the coupling between the NV center spin and a neighboring ¹³C nuclear spin. Our results establish coherent dynamical responses as a versatile probe for quantum geometry, and they pave the way for the detection of novel topological phenomena in solid state.     

民国记者的关系网与新闻采集网

民国时期的新闻采集网是嵌入中国传统关系网的差序格局之中运作的。关系网在提高记者新闻采集工作效率的同时也使其复杂化,这主要表现为新闻采集网的规模受制于关系网的缩胀,新闻采集网与关系网形成高度共生关系,以及关系网内外呈现出竞合并存的矛盾态势。     

Technological feasibility of biodiesel production from bioaugmented hydrolysate of waste sludge in a municipal wastewater treatment plant

The hydrolysate of waste sludge was used as the feedstock of biodiesel production, and its technological feasibility was investigated. Waste sludge, collected from No.3 Municipal Wastewater Treatment Plant of Xi＇an, was hydrolyzed in two parallel reactors firstly. Yeast was added into one reactor for bioaugmentation, and the other reactor without yeast was used as a control. Then an acid-catalyzed in situ esterification process was carried out to convert the hydrolysate to biodiesel. The results of hydrolysis showed that the reactor bioaugmented with yeast could promote hydrolysis compared with the control one because of an obvious variance in total suspended solid （TSS）, volatile suspended solid （VSS） and soluble chemical oxygen demand （SCOD）. Furthermore, gas chromatography （GC） analysis exhibited that the total volatile fatty acid （VFA） was low in the hydrolysate of bioaugmentation reactor; however, its yield of the fatty acid methyl esters （FAMEs） by in situ esterification was obviously higher when compared with the control one. Therefore, it may be inferred that the hydrolysate of bioaugmentation was mainly inclined to longer-chain fatty acid rather than to VFA. Anyway, an FAMEs yield of 9.24% （wt%） from dried sludge was attained after the 12-d bioaugmentation hydrolysis and succedent esterification. This value was not only higher than that of the control one but also higher than that reported in previous literature. The above results illuminated that it was feasible to produce biodiesel from the bioaugmented hydrolysate of waste sludge.
