Reputational Threat and Image Repair Strategies: Northern Ireland Water’s Crisis Communication in a Freeze/Thaw Incident

December 2010 saw exceptionally harsh winter weather cause major water supply disruption for thousands of Northern Ireland’s citizens. Sustained low temperatures followed by a rapid thaw led to burst water pipes on an unprecedented scale, triggering a water shortage crisis that attracted global media attention. Government-owned Northern Ireland Water (NI Water) received severe criticism for their response to the incident. This article analyzes the reputational threat posed by the crisis and examines the image repair strategies employed by NI Water before, during, and after the event. The crisis was complex and dynamic, requiring a multistrategy response including bolstering, corrective action, mortification, and shifting the blame. However, this was ultimately deemed largely ineffectual since it was more operationally focused than consumer-oriented. The case study adds to the limited research in public sector crisis communication and illustrates how politics and the governmental organizational structure complicated the threat to NI Water’s image.     

中期财务报告准则的比较研究

为提高上市公司会计信息质量，更好地保护投资者利益，2001年11月，财政部发布了《企业会计准则——中期财务报告》。鉴于美国是实行中期报告制度最早的国家，其制度也相对完善，本文拟将我国中期财务报准则同美国的相关准则及国际会计准则IAS34作粗浅的比较分析。通过比较分析，借鉴国外准则之长处，有利于推动我国中期报告理论和实务的发展。     

Asymptotically optimal estimation of smooth functionals for interval censoring, part 1

Estimation in the interval censoring model is considered. A class of smooth functionals is introduced, of which the mean is an example. The asymptotic information lower bound for such functionals can be represented as an inner product of two functions. In case 1, i.e. one observation time per unobservable event time, both functions can be given explicitly. We mainly consider case 2, with two observation times for each unobservable event time, in the situation that the observation times can not become arbitrarily close to each other. For case 2, one of the functions in the inner product can only be given implicitly as solution to a Fredholm integral equation. We study properties of this solution and, in a sequel to this paper, prove that the nonparametric maximum likelihood estimator of the functional asymptotically reaches the information lower bound.

导向磨铣工具在修井中的应用

针对目前小通道套损井找通道困难的实际情况,使用在用原有的磨铣工具,如磨鞋、铣锥的基础上,用现成捞矛杆加工成一定长度的导向杆,或使用钻杆加工成笔尖后制成。根据套损实际情况,导向杆下端部可以加工成椭圆形、平面式或笔尖形状,可以堆焊合金或不焊合金。进行套管修复作业时,先用导向杆引入到原井眼套管内对破损套管进行初期扩径修整,然后下入较大直径常规扩径磨铣工具进行扩径,最后下入密封加固管修复。由于导向杆的引导和扶正作用,阻止了磨鞋、铣锥偏磨,解决了磨损套管现象,现场应用效果显著。

三主桁连续钢桁拱桥整体节点有限元分析

东平水道桥是武广高速铁路上一座四线铁路桁架拱桥,主跨结构为99m+242m+99m的三主桁连续钢桁拱,主桁采用整体节点形式,三主桁内力分析表明中桁处受力最大。节点板联结着主桁、腹杆、横梁、平联等各类杆件,结构及受力均较复杂,节点应力分布是设计中的关键问题之一。文章利用有限元程序对其特殊位置节点板进行应力分析,研究了其应力分布及传力特性,为设计提供依据和给同类桥梁提供参考。研究表明通过调整节点构造和板件刚度,节点具有足够的受力与传力功能。
