1.The Effects of Financial Regulations on Market Qualities and Informed Traders

Author:DAI Xiaoting;ZHANG Jie;JIANG Qinfeng

Source:The Theory and Practice of Finance and Economics,2022,Vol.43

Abstract:利用一个基于代理的人工股票市场,考察了卖空禁令、涨跌幅限制、交易税和T+1结算周期对市场质量和知情交易者的影响。通过平行测定几个市场程式化事实,将系统校准到真实的金融市场后,发现这四种监管都不同程度地降低了市场波动、价格扭曲和交易量。买卖价差在卖空禁令、交易税和T+1结算周期下增加,但与涨跌幅限制存在非单调关系。当涨跌幅限制政策较为紧时,买卖价差很小,随着涨跌幅限制的放宽,买卖价差增大。一旦市场上不考虑涨跌幅限制,它仍然会下降。此外,在卖空禁令、涨跌幅限制或T+1结算周期的政策下,知情交易者的交易量比例和财富份额均下降。与之相反,交易税给出了相反的结论,即在交易税下,知情交易者的活动百分比增加...

Author:Abid, F;Li, C;Alam, M

Abstract:Subjectivity detection in the text is essential for sentiment analysis, which requires many techniques to perceive unanticipated means of communication. Few accomplishments adapted to capture the syntactic, semantic, and contextual sentimental information via distributed word representations (DWRs)(1). This paper, concatenating the DWRs through a weighted mechanism on Recurrent Neural Network (RNN) variants joint with Convolutional Neural network (CNN) distinctively involving weighted attentive pooling (WAP)(2). Whereas, CNNs with traditional pooling operations comprise many layers merely able to capture enough features. Our considerations empower the sentiment analysis over DWRs contains Word2vec, FastText, and GloVe to produce dense efficient concatenated representation (DECR)(3) to hold long term dependencies on a single RNN layer acquired by Parts of Speech Tagging (POS) explicitly with verbs, adverbs, and noun only. Then use these representations gained in a way, inputted to CNN contain single convolution layer engaging WAP on multi-source social media data to handle the issues of syntactic and semantic regularities as well as out of vocabulary (OOV) words. Experimentations demonstrate that DWRs together with proposed concatenation qualified in resolving the mentioned issues by moderate hyper-parameter configurations. Our architecture devoid of stacking multiple layers achieved modest accuracy of 89.67%% by DECR-Bi-GRU-CNN (WAP) on IMDB as compared to random initialization 81.11%% on SST.

Author:Qian Hongtu;Zhu Yongsheng;Deng Guangmin;Liu Wen;Chen Dunjun;Pei Yi

Source:Journal of Power Supply,2019,Vol.17

Abstract:To achieve a higher power conversion efficiency, a cascode structure based on 650 V gallium nitride high electron mobility transistor(GaN HEMT) was introduced, together with its applications in wireless power transmission. From the aspect of GaN HEMT design, the effects of field plate design on capacitance and electric field were discussed through simulations. The fabricated cascode device had a leakage current of 2 muA at drain-source voltage of 650 V. At 400 V, the input capacitance C_(iss), the output capacitance C_(oss) and the reverse transfer capacitance Crss were 1 500 pF, 32 pF and 12 pF, respectively, and the dynamic on-resistance increased by about 16%%. Based on the design of this cascode device, a wireless charging prototype with operation frequency of 240~320 kHz and full-load power of 1 kW was designed and presented. Compared with the equivalent Si device, its efficiency was obviously higher within the load range of 200~1 000 W, with the peak efficiency higher than 95%%.

Abstract:Objective: To propose a fast and reliable method for the determination of intracellular lipid accumulation. Method: Lipid accumulation in HepG2 cells were induced by oleic acid. Lipid droplets were stained with BODIPY 493/503 and measured with fluorescent image processing using Matlab or ImageJ. The images results were compared to those of Adipophilin,a widely served marker for lipid accumulation,which were determined from protein and mRNA levels by Western blotting and qPCR. Result: By processing fluorescent images using BODIPY 493/503 staining for lipid droplets and comparing data outputs with Matlab and ImageJ, a method using Matlab as image processing platform was established for the determination of intracellular lipid accumulation ; a 1. 41 - fold increase in oleic acid - induced lipid accumulation was detected by fluorescent image processing, which were in accordance with the markedly enhancement in Adipophilin protein levels (2. 07 - fold) and mRNA levels (1. 53 - fold). Conclusion: The method combining fluorescent staining and image processing shall help analyze the intracellular lipid accumulation both rapidly and accurately.

13.Combinations of fungal and milling pretreatments for enhancing rice straw biogas production during solid-state anaerobic digestion

Author:Mustafa, AM;Poulsen, TG;Xia, YH;Sheng, KC

Source:BIORESOURCE TECHNOLOGY,2017,Vol.224

Abstract:Rice straw was pretreated by different combinations of physical (milling) and biological (incubation with Pleurotus ostreatus fungus) treatment to improve its biodegradability and biogas production during solid-state anaerobic digestion (SS-AD). Effects of milling (62 mm) and incubation time (10, 20 and 30 d), on lignin, cellulose, and hemicellulose degradation during fungal pretreatment and methane yield during digestion were assessed by comparison with untreated rice straw. Both incubation time and milling had significant impacts on both lignin removal during fungal pre-treatment and methane yield during digestion. A combination of fungal pretreatment at 30 days followed by milling prior to anaerobic digestion resulted in 30.4%% lignin removal, the highest selectivity value (the ratio between relative lignin removal and relative cellulose removal) of 4.22, and the highest methane yield of 258 L/kg VS. This was equivalent to a 165%% increase in methane yield from SS-AD compared to untreated rice straw. (C) 2016 Elsevier Ltd. All rights reserved.

14.The Integrative Mechanism of Organizational Response to Institutional Complexity from Organizational Identity Perspective —A Case Study on One WISE Social Enterprise

Author:Xu Siqi;Xi Youmin

Source:Luojia Management Review,2020,Vol.

Abstract:组织如何有效应对制度复杂性是一个日益关键的管理问题,但已有研究仅提出了针对制度复杂性单一方面的应对策略与机制。本文采用建构式扎根深度单案例研究方法,以一个工作整合型社会企业为对象,从组织身份视角出发,探索了组织整合地有效应对制度复杂性的过程与机制。研究结果表明:组织通过价值过滤和学徒工作能动地构建了基于价值的组织身份,直接消解了归属复杂性;而基于价值的组织身份塑造了以手段为核心的心理参照点,间接地同时平衡了绩效与运营复杂性。研究弥补了已有制度复杂性应对文献片面化的缺陷,发现了构建能整合应对制度复杂性的组织身份的两个关键构念,对组织解决内部冲突和进行人力资源管理具有指导意义。

15.Post-Structural Theories and Chinese Feminist Criticism: On the Theorization of Women’s \"Subjectivity\" in the Cultural Studies of Socialist China

Author:Xi,Liu

Source:Theoretical Studies in Literature and Art,2021,Vol.41

Abstract:Centering on the conceptualization of "subjectivity," ths article first traces the post-structural theories' impact on as well as their compex relationshp with Western feminsm. It then expores the development of the theorization of " womens subjectivity" n academic research on Chnese women and gender dscourses in socialist Chna from the 1980s. By examinng the appication of three influential theorists, Lous Althuser, Michel Foucault, and Judth Butler, n the Chnese context, ths article ntends to show the compex genealogy of "appropriating" post-structural theories for dfferent agendas of contemporary Chnese feminst criticism. Some scholars ntegrated post-structural deas nto iberal-humanst dscourses; some employed post-structuralist feminism to de-essentialize and hstoricize the analysis of "subjectivity" and "agency" of socialist Chnese women; some questioned the effectiveness of post-structural theories n studying the Chnese socialist culture from the perspective of hstorical materialism. Different research paradgms of theorizing " female subjectivity" have proven to be influenced and nformed by the changing deologies and social dscourses in Chna since the 1980s.

Abstract:本研究基于张瑞敏个案的社会化过程,探索了领导特质的类型及其形成与关系。研究结果表明,社会化过程中,领导特质表现为四种类型,即根源型、驱动型、思维型和事务型。根源型特质带有强烈的价值判断,积淀并固化于领导者的潜意识中,具有强烈的稳定性,是领导特质的核心层及领导者成长的根本依赖。驱动型特质是不带有价值性判断的领导者自身的主观行为特征,是形成其他领导特质的动力基础。思维性特质是领导者思维意识层面的特质,体现于对待事务时的思维模式。事务型领导特质是领导者对待事务时所呈现的特质,这种特质会依据思维特质的作用而有选择地呈现于领导行为。根源型特质与驱动型特质基于关键事件冲击后领导者的感悟而形成,两者相互激发...
