公路工程施工项目特殊季节与夜间施工安全控制要点

由于公路工程施工项目多数属于点多线长、露天和连续作业,涉及的人员、材料、机械设备多,技术含量低且需要经常变换工种的施工环境,使得安全风险大,因此,各施工单位必须对夜间和季节性施工安全措施高度重视,针对夜间施工和未来特殊气候环境影响下施工中可能发生的造成人员伤亡、疾病、财产损失、工作环境破坏等危险及紧急情况,采取有针对性的事先预防措施。     

转型时期人民当家作主主体自觉性缺失与构建探讨

党的十八大强调夺取中国特色社会主义新胜利,必须坚持人民主体地位。笔者分析了我国转型时期主体自觉性缺失对人民当家作主的制约,提出了通过健全各项民主制度扩大人民当家作主的群众基础、加强法制宣传教育以增强人民依法维权自觉性、建设社会主义核心价值体系提供精神动力和思想保证等措施来构建人民当家作主的主体自觉性。     

Protection for sale under monopolistic competition: Beyond the CES

We extend the protection for sale model of Grossman and Helpman (1994) by introducing a general model of monopolistic competition with variable markups and incomplete pass-through. We show that the structure of protection emerging in the political equilibrium not only depends on the weight attached by the government to consumer welfare when making its policy decision, but also on the degree of market power of firms and on the terms-of-trade variations due to the degree of pass-through. Our results highlight the importance of preferences in shaping the structure of protection and are consistent with the occurring of protectionism also in unorganized industries.     

Quantitative Easing Forever? Financialisation and the Institutional Legitimacy of the Federal Reserve’s Unconventional Monetary Policy

Scholars of financialisation have argued that the emergence of finance-led grow regimes requires new instruments for effective conduct of economic policy. In this scholarship, central banks have been seen as the most promising actors to utilise one of the most synergetic policies, the maintenance of high and stable prices of financial assets. Since the financial crisis of 2007–8, central banks of the developed world have adopted various unconventional monetary policy measures that serve this function. But will these unconventional measures become institutionally legitimate and institutionalised as conventional practice, as suggested necessary by scholars of financialisation? In this paper, we answer to this question by studying the institutional legitimation of the Federal Reserve’s Quantiative Easing (QE) programmes. We argue that the QE programmes have been legitimated successfully but with institutional legitimation strategies, which cause institutional pressures that question the potential of QE from becoming a regular policy instrument and practice.     

湘桂铁路下穿全兴高速公路设计方案优化

新建湘桂铁路于DK233+503处下穿全兴高速公路,原设计采用顶进框架桥方案。通过对安全质量的可控性、经济、工期等方面进行综合比选,取消顶进框架桥,变更为公路箱梁桥上跨铁路方案,采用分幅封道、分幅施工,既安全快速地穿过全兴高速公路,又创造了良好的经济效益和社会效益,为类似的工程提供了一定的参考价值。

PLC液压控制系统在桥梁整体同步顶升中的应用

新建桥梁与原有旧桥梁的对接如何进行,尤其是对刚投入使用不久的桥梁改造,应从经济、环保、交通、使用价值安全等多方面考虑。桥梁整体可靠程度将直接影响桥梁结构的安全度和耐久性,PLC液压控制系统能够有效解决桥梁上部结构在顶升、降落过程中同步位移的难题,保证桥梁的整体性。     

以廉政勤政简政为指引全面提升政府公信水平

近年来,我国政府公信力建设取得了巨大的成就,但也存在政策之间的协调性和行政体制的结构矛盾十分突出、政府公共服务和信息公开不能满足民众要求等问题. 要全面提升政府公信水平,就要深化行政体制改革,建立政府信用水平评价体系,推进政府信息透明化,完善政府对自身债务的管理,积极引导网络舆情.     

利用气井历史生产数据计算动态储量新方法

气藏动态储量是指参与渗流的地下气体地质储量,计算动储量常采用物质平衡法,但是对于难以获得平均地层压力的致密气藏不适用。本文介绍了利用气井长时间生产数据计算动态储量的方法,并研究采用叠加时间函数(Super-t)分析变产量修正时间,使计算结果更加精确;同时应用该方法对苏东南区致密砂岩气藏部分气井进行单井动态储量计算,为该区动储量估算提供借鉴。
