The growth and expansion of tourism is a complex phenomenon and its study requires multiple disciplines. When related to sustainability, the growth limits and carrying capacity of destinations must also be considered. The objective of this article is to develop a methodology to assess the growth limits of tourist destinations, and this method is then applied to the management and planning of an open tourist resort. The limits to growth are established using a mathematical formulation (i.e., multicriteria analyses, based on the reference point methodology) based on synthetic indicators applied to two scenarios: weak and strong sustainability. There are two developments in this type of research. The first is that the application of this method is neither restricted to a natural protected area, which has its own rules and management, nor to an island possessing geographically controlled entry and exit points. Rather, this study focuses on an open coastal area with an economy based on mass tourism. Second, this new way of assessing growth limits uses a flexible formula – adaptable to other coastal areas, e.g., rural, natural, and urban – depending on the impacts generated by the tourism and the objectives specified by destination managers.  相似文献

We devise future-oriented technology analyses tools to investigate a technology at an interesting development stage of early emerging applications. At this stage, technologies show great potential with little established commercialisation. Future development pathways are highly uncertain and heavily dependent on contextual interactions. We apply R&D profiling, R&D-to-applications cross-charting, and technology delivery system modelling to help understand the phenomena that bear upon development prospects. We develop our approach through a two-tier case study: general treatment of nanomaterial-enhanced biosensors, followed by more specialised treatment of one subset of those. Results convey the importance of considering technological and social context factors together to understand likely innovation pathways.  相似文献

第三方物流提供了所有的物流活动。他们在第一方(供应商或生产商)和第二方(买方或顾客)之间扮演着桥梁或设施供应商的角色。第三方物流提供商的基本目标是降低供应商的整体物流成本,提高顾客服务水平。成本降低和对更好更便宜的服务的需求是增长背后的动力。  相似文献

The aim of this study is to explore the relationship between perceived ethical obligation and subjective norms as well as their simultaneous influence on CSR related choices. A scenario based experimental approach was employed. Our results indicated that subjective norms strengthen the explanatory power of the model. Subjective norms are additionally found to have a mediating effect on perceived ethical obligation.  相似文献

Engineering and improved road safety education has resulted in an overall decrease in road traffic accident numbers in Christchurch, New Zealand. The temporal trends of crash data from 1980 to 2004 reveal that lowering of crash rates is not occurring at a uniform rate throughout the day, with comparative increases in crash rates occurring during morning rush hour, and during the ’school run’. No spatial clustering around schools was identified. This suggests that policies to reduce school travel related road accidents need to be focused on reducing overall traffic levels rather than focusing geographically on areas in the immediate vicinity of schools.  相似文献

The urban growth of large cities in China is at a critical stage with the booming of the economy and impressive increase of the population and traffic demand. This paper studies and qualifies the growth and accessibility of a rapid rail transit network, and characterizes the relations with urban development using a spatio-temporal modelling approach. Several measures of the network topological structure, i.e., beta index (β), cyclomatic number (μ), alpha index (α) and gamma index (γ), are selected in order to examine and quantify the overall metro network growth of the city of Guangzhou in China. The results show that the current spatial connectivity of the Guangzhou’s metro network is relatively low, this stressing the need to augment the reliability of the connections between the network nodes, and to increase the number of circuits in the network. A travel-time matrix is modelled and evaluates the nodes accessibility and characterizes the spatio-temporal evolution of the metro network. The spatial interaction between the different nodes of the network, as well as nodes accessibility are analyzed and derived from a potential-based model. The extension of the metro network clearly shows a dramatic tendency of positive accessibility evolution but with regional differences. In particular, the core of the city is surrounded by areas with highest accessibility values and gradually expanding outward from the core, while the locations of transfer stations have significant influence on the variation of network time-based accessibility. Taking into account different network development scenarios, the approach reveals regional accessibility differences in the metropolitan area of the city of Guangzhou, this clearly illustrating the impact of network accessibility in urban development.  相似文献

During the last few years, car sharing has undergone significant growth, both in Canada and around the world. In this type of service, users share access to a fleet of vehicles, thereby giving them most of the advantages of automobile use, such as its temporal and spatial flexibility, without many of the constraints of ownership. This study analyzes the geographical and socio-economic factors that favour membership of a carsharing service in Québec City. We combined Cervero’s and Kockelman’s 5D model (density, diversity, design, distance to transit, and destination accessibility) with Hägerstrand’s concept of innovation diffusion so as to analyze the evolution of potential car-sharing membership. Zero-inflated negative binomial (ZINB) regression was used to model the spatial diffusion of the number of car-sharing members in Québec City from 1996 (two years after its inauguration) to 2008 at the local scale, with an annual time step. Results indicate that the carsharing distribution did, indeed, follow Hägerstrand’s innovation diffusion model and that, even though some of the 5D model significantly influenced membership, it was socio-economic factors (education, non-motorization, and family structure) that most greatly affected the membership rate in the service area. The model is used to assess and discuss market coverage potential in Québec City.  相似文献
