在BSV模型下矫正投资者对信息的认知偏差

Barberis、Shleifer和Vishny(1998)基于投资者认知市场信息过程中出现的心理偏差，解释了过度反应和反应不足现象，并在BSV模型的框架下，进一步引入了一个心理矫正中介来矫正投资者对市场信息的认知偏差。通过建立市场管理者与中介机构之间的委托一代理体制，发现确实有可能存在此类中介。市场管理者可以制定出一套针对此类中介的最优激励机制，对其进行监督管理。

Research agenda for low-carbon mobility: Issues for New World cities

ABSTRACT

Low-carbon mobility (LCM) features strongly in debates about the sustainability of cities and their resilience in the face of demographic, economic, and climate change. Transport is a major source of carbon emissions and there are indications that these continue to increase, despite the considerable recent advances in vehicle, engine, and fuel technologies. Reducing carbon emissions from transport may become more difficult, not easier. A particular issue relates to the New World cities, typified by those of North America and Australasia, which largely developed from the latter half of the nineteenth century onward and whose transportation systems were largely based around private vehicle ownership and usage. These cities are typically composed of low-density, dispersed suburbs, which are highly car dependent and resource and carbon emission intensive. This article develops a research agenda directed at determining and testing policy and planning measures relevant to the quest for low carbon mobility in New World cities. It suggests a rich agenda for essential research on LCM. Much of this agenda falls within the realm of the integration of transport and land use, with attention to urban design details to enhance the perceptions of and opportunities to use low carbon transport alternatives. Research topics identified for LCM research include (1) urban design and land use–transport integration (LUTI), (2) low carbon mobility policies directed at achieving widespread behavior change, (3) opportunities for new technology and its application, including requirements for systems and infrastructure, and (4) analysis and tools for informed decision making, including modeling, measurement, visualization, and especially assessment.     

Environmental scanning the future of event design

This paper used multiple sources of information in order to identify the forces likely to impact event design. Content analysis of key informant interviews and selected trade publication articles identified key forces impacting event design. Technology, the environment and green issues, security and safety, and globalization were forces identified by both the key informants and the trade literature. Neither of the sources gave much attention to political forces. This article contributes to our understanding of the forces impacting event design and suggests some environmental scanning methodologies that can be used with both key informants and the trade publication literature.

冲淤平衡稳定渠道的优化设计

本文针对渠道冲淤平衡特点，将优化技术与最小能耗率原理相结合，提出了一个能够反映实际情况的冲淤平衡稳定渠道优化设计方法并用实测资料对计算结果进行了验证，两者符合较好．     

适用于河流治理的地面廊道污水处理系统的设计

地面廊道污水处理系统类似于人工湿地技术，其优点在于该系统应用于污染河流的治理时，对河流地形适应性非常强；另外系统四周不透水的墙体结构使整个廊道起着氧化塘的作用，并且沿坡降由好氧塘逐渐过渡到厌氧塘。本文重点介绍该处理系统的设计，主要包括廊道的选址．水生植物的选择．廊道最佳长度及运行参数的确定。

膨胀性岩体隧洞的设计与施工

临汾草峪岭隧洞围岩为二迭系弱－中等膨胀性岩体。这类膨胀性岩体的主要特性为：含粘土量５０％，浸水后膨胀量２－１１％，膨胀压力４４－１７２ｋＰａ，初始含水量高，风化速度快，放置洞外４８ｈ后就风化崩解，最大特点是当其初始含水量损失超过４０％时才产生风化崩解现象，针对此种围岩特性，在隧洞设计施工中采取以下措施，取得了较好效果：（１）光面爆破，短循环开挖，以尽量减少爆破对围岩的破坏作用；（２）快速封闭围岩以     

岸坡上桩基码头设计方案的分析比较

本文结合实际工程对码头桩基和岸坡相互作用的计算表明，桩基的受力和位移与其离岸的远近、倾斜方向有密切的关系；为抵御岸坡的水平位移，在后平台增设斜顶桩对改善桩基的受力条件和减少码头位移有较为显著的作用。
