Most small-scale social economies are characterised by their deficiency, lack, and/or difficulty in matching natural data. Against this backdrop, this paper builds a relatively uniform theoretical framework and designs a more economical and objective method for demarcating ecological conservation redlines (ECR) based on sensitivity assessment of ecosystem services. The results show that the sensitivity assessment model designed in this study can identify sensitive zones effectively, and that the ECR in Hubei Province are well within the sensitive zones so identified. The delimited areas based on the sensitive assessment of ecosystem services have great similarities (95%) with the actual ECR areas in Hubei Province. The most ecologically important functional zones (EIFZ) can also be identified using the regional ecological sensitivity coefficient. When the threshold of EIFZ is set higher, the probability that it falls within the ecologically sensitive areas is greater and the ECR delimited by the method proposed in this study will be more reliable. Theoretically, the delimitation of ECR can be inserted at any evaluation level with a grid resolution higher than that of the land use data, which can be used as a supplement to the ECR delimitation method in ecology or geography.  相似文献

This study conducted a large-scale survey in Dhaka, Bangladesh; the survey involved 95 major hospitals, more than 3000 emergency room patients, and 2 of the largest ambulance operators. Currently, most ambulances are parked within the vicinity of hospitals and are either dispatched or fetched by the acquaintances of the patient on demand, resulting in lengthy round trips. Reducing the response time of ambulances would certainly improve the emergency service, and pre-positioning of the ambulances could be a solution to reducing the response time. This study used two approaches to address the problem. First, the location-allocation problem was solved to find the optimal number of ambulance locations by maximising the demand coverage. Second, separate location-allocation for the peak and off-peaks, using K-means clustering, was applied to systematically optimise the ambulance positioning in small clusters near demand points. These approaches could substantially improve the existing emergency response time. Distributing ambulances near demand points yielded greater improvements in response time than when the ambulances are stationed near hospitals.  相似文献

The purpose of this paper is to evaluate the board roles that make a board effective in the performance of adopting corporate social responsibility (CSR) practices. This paper examines directors' perceptions of the three main roles: monitoring, service, and strategic, which provide tools for critically understanding how the board adds the value in moving the organization towards more CSR practices. The stakeholder theory is used to distinguish the influence of the three main roles on the adoption of CSR practices. Primary data were collected for this research by conducting structured questionnaires with a sample of 461 directors from Saudi listed companies for study purpose. The results show that an appropriate mix of directors' roles and the development of sound board monitoring and service roles are the most crucial determinants of CSR adoption in Saudi listed companies. As the extant corporate governance and CSR literatures do not provide a clear perspective with contradictory outcomes about board roles in influencing CSR practices, the originality of this research is its contribution by evaluating the directors' perceptions of developing a direct relationship between the board roles and the adoption of CSR practices. Furthermore, the use of the stakeholder theory provides additional insights into identifying the most influential board role factors enhancing stakeholders' expectations of CSR practices.  相似文献

This study make provides service marketers, particularly those delivering information technology (IT) related service, with insight to the factors that consumers use when evaluating IT services. We develop a service continuance model that includes the antecedents of the consumer׳s decision to continue using information technology (IT) related services in a B2C service environment. Using data from the smart phone service consumers, a covariance-based structural equation modeling analysis is used to test the research model. Results from our empirical study suggest that the association between service usefulness and service continuation intention is fully mediated by service satisfaction. Though both system-service quality and customer-service quality are positively associated with service satisfaction, consumers of IT related services attach greater importance to system-service quality than to custom service quality. Likewise, the indirect path to service continuation intention is stronger in system-service quality than in customer-service quality. Our findings have practical implication for growing market share in IT related services by recognizing the importance of system-service quality in technology service delivery.  相似文献

以国家会议中心各部门的一线服务人员及其所服务的客户作为主要调查对象,259份有效问卷作为样本,利用SPSS20.0对调查结果进行典型相关分析,探析了员工授权知觉与服务质量的关系。结果表明:组织员工授权知觉和员工服务质量之间存在正相关关系,员工对自己工作能力的信心强度和对自己是否拥有工作自主权与独立权的感知程度更能有效的影响到客户对员工服务质量的评价,在提高员工授权知觉的情况下,员工的服务质量会得到提高,并凸显在服务的效率和可靠性这两方面。对一线服务员工进行适当的放权,使其授权知觉水平提高,有利于增强员工自信心,树立员工的责任感和价值感,提高员工服务工作的效率及可信赖性。  相似文献

The number of payments for environmental service schemes (PES) in low-income countries has grown more rapidly than in high-income countries. Yet, scarce funding among potential service buyers in low-income countries arguably makes it even more important to design PES cost-effectively. Tendering conservation contracts is one possible way to improve the cost-effectiveness of PES schemes. There is reason to believe that they are particularly well-suited to overcome some typical constraints in low-income environments. However, experience with conservation tenders in low-income countries remains limited to a handful of scientifically motivated experimental trials. Larger roll-outs can so far only be found in high-income countries, mainly the US and Australia. How different would rolled-out PES tenders perform in low-income countries, and would they require distinct design features? Here, we identify specific opportunities and challenges for implementing conservation tenders in low-income countries. Conceptually, we examine each implementation step of a tendered PES for typical low-income country characteristics. Some may affect the design requirements for successful implementation, in either positive or negative ways, compared with the typical high-income country case. Imperfect markets and information about production systems, high subsistence incomes, high variability in prices and yields, and risk-averse behavior all constitute characteristics which conservation tenders may be particularly suited to address. Conversely, lack of expertise and infrastructure can hamper tender design and the dissemination of information to potential participants. Some of these challenges can be dealt with, but solutions unavoidably increase transaction costs which, in turn, may affect scalability. While tenders reduce poverty alleviation effects when informational rents of service providers are being squeezed, tendered PES programs do not reduce rents to zero under normal circumstances, and can therefore still deliver income transfers and contribute to poverty alleviation.  相似文献

Despite the importance of retaining customers in the context of e-shopping, the formation of an e-buyer’s loyalty remains inconclusive. Drawing on e-shopping literature, this study developed and tested a model to explain e-buyer loyalty from the perspective of business-to-consumer relationship management. We build on a dedication-constraint dual model to delineate the relationship between perceived benefits, switching cost, service-specific investment, and loyalty. Empirical results from 505 respondents show that loyalty is influenced by both perceived benefits and switching costs. In addition, switching costs partially mediate the relationship between service-specific investments and loyalty. Implications of these results are discussed.  相似文献

Off-payroll workers in the UK, including personal service companies (PSCs), engaged by the public sector have been giving ‘assurance’ of their tax position to departments in the sector since 2012. Departments must be satisfied with the assurance. For PSCs this requires awareness of complex tax legislation (IR35), which is aimed at preventing tax avoidance. Costs may be incurred in attaining the necessary knowledge. This may bring into question costs incurred in protecting tax revenue. No similar obligation exists in the private sector.  相似文献
