Tourism's role in urban regeneration: examining the impact of environmental cues on emotion,satisfaction, loyalty,and support for Seoul's revitalized Cheonggyecheon stream district

This study explores the use of sustainable tourism as a tool for the regeneration and “greening” of urban areas. It is based on evidence from the revitalization of the Cheonggyecheon stream district in downtown Seoul, a process that emphasized nature conservation and recreational opportunities. The purpose of this study is to examine the impact of environmental cues on emotion, satisfaction, loyalty, and support for the revitalized Cheonggyecheon stream district by applying a stimulus–organism–response framework. We conducted an on-site survey on visitors to Cheonggyecheon during November 2010. The results indicated that environmental cues from the revitalization arouse positive emotions that lead to visitor satisfaction and loyalty, which, in turn, bring about strong support for the stream and further tourism development. Structure and ambiance affected both positive emotion and satisfaction. Visitors appreciated not only nature, but also man-made facilities (e.g. culture center, artificial waterfall, fountain, artwork, stepping stones, lighting, signage, and nightly laser show) that aroused positive emotion and satisfaction. A strong case is made for long-term and holistic planning to maintain the natural and man-made surroundings of Cheonggyecheon in order for it to remain popular with visitors and residents. Discussions and implications are drawn from the findings.

高维数据流子空间聚类发现及维护算法

近年来由于数据流应用的大量涌现,基于数据流模型的数据挖掘算法研究已成为重要的应用前沿课题.提出一种基于Hoeffding界的高维数据流的子空间聚类发现及维护算法--SHStream.算法将数据流分段（分段长度由Hoeffding界确定）,在数据分段上进行子空间聚类,通过迭代逐步得到满足聚类精度要求的聚类结果,同时针对数据流的动态性,算法对聚类结果进行调整和维护.算法可以有效地处理高雏数据流和对任意形状分布数据的聚类问题.基于真实数据集与仿真数据集的实验表明,算法具有良好的适用性和有效性.     

Value stream mapping in project management: A case study

This article describes the application of value stream mapping to analyze and redesign the way of managing the materials procurement stage of a project. A framework based on integrated definition (IDEF) methodology, the stream analysis approach, activity‐based costing, and discrete event simulation is presented. The stream analysis approach is used to analyze, diagnose, and manage process changes represented using an IDEF model. A dynamic simulation is used to evaluate the impact of the changes considered, to support the analysis of the process, and to model the performance of the proposed process. The overall methodology is demonstrated by applying it to a company whose core business is the design and construction of offshore oil rigs. The company specializes in engineering, procurement, and construction projects and has an annual portfolio of about six projects. Many of these projects have common features in terms of design and components, and they are all also characterized by a short “time to delivery.” For this reason, this study was aimed at assessing the possible effects that the application of new materials management policies could have on reducing both project completion time and the resources required.     

The co-evolution of third stream activities in UK higher education

This paper explores the co-evolution of third stream activities in UK higher education from 1970 to 2008. Drawing on interviews and archival analysis it identifies four distinct periods through which third stream activities have co-evolved. The research suggests that the co-evolution of the third stream mission in universities is inextricably linked to the emerging requirement for universities to demonstrate they have a purpose in society. It concludes that the rise of third stream activities has presented both universities and government with a means of doing this.

Cash Stream Valuation In the Face of Transaction Costs and Taxes

The usual notion of every future cash stream having a net present value determined from a single term structure breaks down when transaction costs are taken into account, especially the sizable costs associated with short-borrowing. the difficulties are compounded by taxes, which can lead to paradoxes of disequilibrium if elementary NPV is assumed to be a rational basis for decision making. This paper systematically develops a theory of valuation which overcomes these shortcomings by accepting the multiplicity of no-arbitrage term structures that may be present for each tax class of investors, and uses the entire set of them to impute both a "long price" and a "short price" for every cash stream, regardless of the sign of the future payments. the valuation operators giving these prices are nonlinear but readily calculated from linear programming formulas.
