股价异常波动危害投资者权益和股市安全,厘清股价异常波动的原因对于股市监管具有重要意义.本文从个股高频数据中提取股价中的私有信息含量,检验私有信息与中国A股市场个股异常波动的关系,并基于独特的账户数据分析个人投资者行为在这一关系中的作用.结果表明,排除市场因素的影响后,无论是否有公司层面的消息发布,私有信息都与股价异常波动的发生概率显著正相关,而个人投资者在这一关系中发挥了中介作用.进一步的研究发现,个人投资者的中介作用在股价暴涨和暴跌时有显著的非对称性:在股价上涨过程中,私有信息促进了个人投资者跟风买入的助涨行为,增大了股价暴涨的概率,而在股价下跌过程中,私有信息抑制了其抄底买入的止跌行为,也增大了股价暴跌的概率.本文的启示是,中国股市个股暴涨常常受到机构投资者和个人投资者的共同推动,而个股暴跌则是伴随机构投资者推跌和个人投资者提供流动性稳定股市的过程.

高职院校作为孵化高素质技能型劳动人才的摇篮,劳动教育的实施质量将直接影响一线劳动者的质量,进而影响技能型社会的建设进程。而教育之成败系于教师,构建劳动教育教师学习共同体,促进教师专业发展,将助推高职院校高质量发展,赋能技能型社会建构。劳动教育教师学习共同体以“以劳促全”为共同价值目标,以“劳动精神、工匠精神、劳模精神”三个塑造为共同使命愿景,以“提高劳动教育素养”为共同归属。依据群体动力学理论,要通过明确主体、重塑观念、重建文化提高学习共同体的凝聚力和驱动力,通过完善制度降低耗散力的破坏性,从而促进高职劳动教育教师学习共同体的建构。

hnpurity-free intermixing of InGaAsP multiple quantum wells （MQW） using sputtering Cu/Si02 layers followed by rapid thermal processing （RTP） is demonstrated. The bandgap energy could be modulated by varying the sputtering power and time of Cu, RTP temperature and time to satisfy the demands for lasers, modulators, pho- todetector, and passive waveguides for the photonic integrated circuits with a simple procedure. The blueshift of the bandgap wavelength of MQW is experimentally investigated on different sputtering and annealing conditions. It is obvious that the introduction of the Cu layer could increase the blueshift more greatly than the common impurity free vacancy disordering technique. A maximum bandgap blueshift of 172nm is realized with an anneal- ing condition of 750~C and 200s. The improved technique is promising for the fabrication of the active/passive optoeleetronic components on a single wafer with simple process and low cost.

The Journal of China Universities of Posts and Telecommunications 2013年第5期20卷 104-109页

作者： HAN Ting LUO Shou-shan zhu hong-liang XIN Yang Information Security Center Beijing University of Posts and Telecommunications National Engineering Laboratory for Disaster Backup and Recovery Beijing Safe-Code Technology Co.Ltd.

This paper presents a novel trust model based on multiple decision factor theory （MDFT） and a trust routing algorithm based on MDFT to exactly evaluate routing node trust and establish a trustworthy routing path. MDFT integrates four dimensional trust decision factors including behavior, state, recommend and node liveness to realize an exactly finer-grained trust evaluation. On the basis of MDFT, a trust routing algorithm is presented and validated in open shortest path first （OSPF） protocol. Simulation resuRs show that the algorithm can reflect the routing node trust accurately and has better dynamic response ability. Under the circumstance of existing deceptive nodes, the algorithm has better anti-deception performance and higher attack node detection rate than conventional algorithm.

Two thermostable glucoamylases were produced from Aspergillus niger B-30 by submerged fermentation. The two glueoamylases GAM-1 and GAM-2 were purified by ammonium sulfate precipitation, diethylaminoethyl- cellulose fast flow（DEAE FF） and Superdex G-75 gel filtration columns. The molecular weights of GAM-1 and GAM-2 were determined as 9.72x 104 and 7.83x104 by sodium dodecyl sulfate-polyacrylamide gel electrophoresis （SDS-PAGE）, while the molecular weights of GAM-1 and GAM-2 were determined to be 8.05x 104 and 7.04x 104 by matrix assisted laser desorption ionizationtime-of-flight（MALDI-TOF） mass spectrometry, respectively. Both the enzymes were glycosylated, with 10.4% and 11.4% carbohydrate content, respectively. The optimal pH and tempera- ture were 4.0--4.6 and 70 ℃ for both. The two glucoamylases were maintained 100% relative activity after incuba- tion at 60 ℃ for 120 min. After the hydrolysis of starch for 120 min, glucose was the only product, confirming that the two enzymes were of high efficiency towards starch. The GAM-2 exhibited higher catalytic activity towards oli- gosaccharides such as maltose than GAM-1, and the kinetic analysis shows that the affinity of GAM-2 to starch was lower than that of GAM-1. The high thermostability and effectiveness make the two glucoamylases potentially attrac- tive for biotechnological application.
