Trader Anonymity, Price Formation and Liquidity

Using data from the Frankfurt Stock Exchange we analyze priceformation and liquidity in a non-anonymous environment withsimilarities to the floor of the NYSE. Our main hypothesis isthat the non-anonymity allows the specialist to assess the probabilitythat a trader trades on the basis of private information. Heuses this knowledge to price discriminate. This can be achievedby quoting a large spread and granting price improvement totraders deemed uninformed. Consistent with our hypothesis wefind that price improvement reflects lower adverse selectioncosts but does not lead to a reduction in the specialist's profit.Further, the quote adjustment following transactions at thequoted bid or ask price is more pronounced than the quote adjustmentafter transactions at prices inside the spread. Our resultsindicate that anonymity comes at the cost of higher adverseselection risk. JEL Classification: G10.

悬浮床加氢裂化工艺技术经济分析

介绍了重油悬浮床加氢裂化工艺的最新发展，对国内新开发的悬浮床加氢裂化工艺特点作了介绍。并将悬浮床加氢和三种重油轻质化工艺——固定床加氢、延迟焦化、重油催化裂化在技术经济上作了分析对比。在原油品质越来越差的今天，针对劣质重油而开发的的悬浮床加氢裂化工艺具有非常广阔的应用前景。     

予力砼结构裂缝控制验算的简化

传统的预应力砼裂缝控制，计算公式繁琐，参数多杂，令人望而生畏。对整体砼结构的计算结果，代表性差。采用索粱分栽法，可以妥善解决这一问题。由索结构承担的荷载产生挠度裂缝在建造过程中由予力完成。而使用状态下裂缝的开展及宽度的控制，则由普筋和索非予力部分承担的荷载产生。同设计普筋结构一样，一般结构可以不需详细验算裂缝的开展。

施工中高层框剪结构住宅楼板开裂的预防和处理

进入21世纪以来,人们生活水平不断提高,现代社会对建筑施工项目整体质量要求越来越高。随着高层建筑物数量的增加,建筑物中高层框剪结构住宅楼板施工面临着更大的挑战。要想满足现代社会对建筑整体质量的实际要求,施工企业必须结合实际建设状况,不断强化中高层框剪结构住宅楼板施工,为提升建筑物的整体质量提供技术保障。但是,在实际施工建设过程中,建筑物中高层框剪结构住宅楼板施工受诸多因素的影响仍存在较多问题,如楼板开裂、脱落以及老化等。中高层框架结构一旦出现质量问题,建筑物整体质量将受到严重削弱。因此,建筑施工企业必须采用新技术、新工艺和新材料有效预防和处理中高层框剪结构楼板开裂问题。     

落地式多绳摩擦提升机双层罐笼更换方案

落地式多绳摩擦提升机双层罐笼更换工艺复杂,参与人员多,作业时间长。施工工序主要有拆除安全设施、罐道木,解除罐笼端平衡绳并固定,解除悬挂装置与罐笼的连接轴销并脱开悬挂装置并固定,安装自制专用梁及专用滑车,用稳车和小卷扬拉出旧罐笼、拉入新罐笼,撤出安装专用梁及专用滑车,新罐笼与悬挂装置、平衡绳的连接,安全设施安装,试运行等步骤组成。
