Controlling the morphology of semiconductor nanocrystals has typically relied on controlling the concentration and species of surface ligands utilized in synthesis. Specific shapes, such as branched structures are of particular interest as the light harvesting and charge separating layer in a photovoltaic device. In this work we quantify how changes in the reaction temperature affect the resulting morphology of the nanocrystals. The narrowness of the temperature range over which the morphological transition occurred provides guidance to the tolerances necessary in the synthesis of CdSe utilized in commercial devices on a large scale.

Barrett's esophagus is a premalignant condition caused by gastroesophageal reflux. Once developed, it can progress through varying grades of dysplasia to esoph-ageal adenocarcinoma. Whilst it is well accepted that Barrett's esophagus is caused by gastroesophageal reflux, the molecular mechanisms of its pathogenesis and progression to cancer remain unclear. MicroRNAs (miRNAs) are short segments of RNA that have been shown to control the expression of many human genes. They have been implicated in most cellular processes, and the role of miRNAs in disease development is be-coming increasingly evident. Understanding altered miRNA expression is likely to help unravel the molecular mechanisms that underpin the development of Barrett's esophagus and its progression to cancer.

投资者作为资本市场主体参与者,在投资决策时会影响股市价格,而股市作为市场的晴雨表又反映了国家宏观经济运行状况,因此分析投资者投资决策规律行为至关重要。随着金融学发展,越来越多的研究发现市场参与者理性人假说和市场有效假说不能解释市场运行实际情况。市场参与者的心理、情绪等主观因素会影响股市价格波动,传统的金融学理论很难解释这一现象,因此行为金融学产生并日益发展。羊群效应则是行为金融学一种表现形式,其本质是投资者非理性的从众心理带来的跟随行为。在市场信息不对称的情况下,出于追求声誉排名和报酬激励等原因,投资人体现出跟随其他人进行决策的行为倾向。部分投资人有时仅靠从周边其他投资人得到的信息做出决定,而不是依靠自己的信息与分析。羊群效应具体体现在同一时点上投资者选择买入或者卖出与其他投资者相同的股票。这种在同一时间段不同投资者所表现的行为持续一致性和同步性是羊群效应的直观体现。中国股票市场尚处于发展阶段,市场机制也不成熟,且投资者中个体投资者占绝大部分,有较明显的非理性投资倾向。而且受政策不确定、信息不对称的影响,市场羊群行为更容易导致市场非有效性。在这种情况下,研究羊群效应对股市的影响尤其重要。已有文献对中国股票市场羊群行为进行了检验,但主要关注A股市场。本文对A股,B股市场都进行了实证研究,并重点分析B股市场羊群行为在不同市场条件和不同行业存在的差异。本文从理论出发,对羊群效应的概念及相关理论进行综述,并分析投资者的羊群效应产生的原因包括信息的不完全性、代理人声誉和薪酬结构。基于羊群效应基本概念,本文提出非对称性羊群效应的存在及检测方法。在实证部分,本文重点运用CCK模型对羊群效应的非对称性和行业差异进行实证研究。首先,我们利用2010年至2018年的数据,对上海B股市场是否存在羊群效应进行了检验。其次,我们观察在同一个总体市场中的牛市和熊市是否会出现羊群效应。然后,利用上海B股市场的股票,我们构建了按行业划分的等权重股票组合,以测试每个行业的特定行业特征是否会导致特定行业回报中存在羊群效应。最后,本文对A股市场羊群效应进行了检验,与B股市场进行对比。本文结论主要包括以下几个方面:第一,B股总体市场上没有显著的羊群效应;第二,在B股市场汽车、能源、金融、IT、房地产、运输和公用事业这7个行业中,汽车,能源,金融,IT,交通运输和公共业均存在羊群效应;第三,在牛市和熊市这两种市场条件下,B股市场不同行业的羊群行为存在差异;第四,A股市场在汽车、金融、能源、交通运输这四个行业存在羊群效应。本文的结论表明虽然B股市场以机构投资者为主,该市场的部分行业同样存在羊群行为,这为羊群行为的普遍性提供了证据。此外,羊群行为在行业上存在的差异则可以为构建基于行业的量化交易策略提供行为依据。
