集输管道是石油、天然气的主要运输渠道,承担着能源运输的重大责任。一些重大管线如果发生事故,则给国家造成不可估量的损失。这就迫切需要解决管网事故率高的问题,以减少由此造成的不必要的损失。采用GPS系统来监测长距离集输管道的异常位移,具有全天候、高精度、自动化程度高等特点,并且卫星通信覆盖能力强,信号稳定,相对于人烟稀少的地点,更具有优势。本文介绍了利用GPS(RTK)技术监测集输管道实时位移的方法和实现途径。  相似文献

The identification of mechanisms that encourage the tourism sector to contribute to sustainable conservation is of great interest. The present work proposes the use of destination branding based on contribution to the conservation of the indigenous resources of the rural tourist destination, and studies the effect this has on perceived value for the tourist visiting the destination. A scale of destination brand identity is validated, along with a scale for destination brand positioning and another for perceived value, as viewed by the tourist, of contribution to sustainable conservation. The perceived value scale offers an overall perspective which includes: functional-affective factors; benefits–sacrifices; the pre-visit stage; and the stay in the rural tourism location. These findings make a new contribution to both literature and to the professional sector.  相似文献

Many traditional destination image studies employ a non-comparative assessment approach. This study, however, suggests defining and measuring destination image in a comparative manner (termed ‘relative image’) for the purpose of destination positioning. Using a case study on American leisure travellers’ image of Mainland China, the author proposes and demonstrates the utility of a multi-step procedure of relative image assessment. The author concludes that by utilising competing destinations as a reference frame and replicating tourists’ actual decision-making process, relative image assessment may generate more relevant information and insights for destination marketers.  相似文献

This paper combines the statistical insights of dynamic strategic group analysis with the qualitative richness of historical analysis to explore the modes of entry, expansion paths, and competitive postures of European firms in the U.S. pharmaceutical market. Patterns of entry and market development over a 20-year period are analyzed. The roles of strategic assets and competencies in determining both the entry strategy and the final competitive posture of these firms in the U.S. market are discussed.  相似文献

在现行"谁污染谁治理"的治污体制下,企业出于追求利润最大化的考虑,必然产生将污水偷排滥放的行为.要彻底解决污水治理问题,必须建立新的污水治理体制,能够满足"偷排污水不能获得经济上的利益"的要求.新体制应该是"产治分离",即企业的产品生产和污染治理相分离.企业专注于产品生产,并按预先核定的污水排出量缴纳治污费;组建专业化的公共事业组织专门进行污水处理,并向用户提供可利用的再生水.进行污水处理的公共事业组织具有公益性、非营利性,其人员参照公务员的办法管理.  相似文献

ABSTRACT

The concept paper adopts a positioning type for the purpose of branding services in a transitioning economy. The consumer-based typology is deemed appropriate and relevant as it represents consumer expectations, reflecting the paper’s key argument that consumer-based positioning strategies are appropriate for branding purposes. Consequently, the paper adopts a positioning type for illustrative purpose. The three positioning strategies adopted were—‘service reliability’, ‘social responsibility’, and ‘branding’ apply to the Ghanaian context. The ‘service reliability’ strategy has a ‘universal’ appeal and is the most prevalent in application. The ‘social responsibility’ to a large extent reflects the caring and community-based nature of the Ghanaian society, whilst the ‘branding’ strategy appears more applicable to international than local firms. The paper contributes to theoretical knowledge in its key assertion that the application of consumer-based positioning strategies for branding is appropriate and beneficial. Practically, the derived propositions will guide the manager in decision making on branding.  相似文献

The COVID-19 pandemic has brought devastating impacts of an unprecedented scale to tourism-related businesses due to governments instituting mobility restrictions and business closures worldwide. In this research, we present the results of a survey involving 1212 tourism-related businesses in Jiangxi province, China, in late February 2020. The survey covered various topics, including (1) self-evaluated effects of COVID-19, (2) business responses, (3) social responsibility behavior, and (4) anticipated government policies. Findings from mixed-effects (ordered) logit models revealed that small-sized businesses appear particularly vulnerable to the pandemic. Social responsibility behavior is determined by business size, local pandemic circumstances, and local tourism dependence. Different businesses favor distinct government aid policies. Based on estimation results from our econometric models, we plotted a policy positioning matrix to identify appropriate policy measures for diverse businesses.  相似文献
