Research agenda for low-carbon mobility: Issues for New World cities

ABSTRACT

Low-carbon mobility (LCM) features strongly in debates about the sustainability of cities and their resilience in the face of demographic, economic, and climate change. Transport is a major source of carbon emissions and there are indications that these continue to increase, despite the considerable recent advances in vehicle, engine, and fuel technologies. Reducing carbon emissions from transport may become more difficult, not easier. A particular issue relates to the New World cities, typified by those of North America and Australasia, which largely developed from the latter half of the nineteenth century onward and whose transportation systems were largely based around private vehicle ownership and usage. These cities are typically composed of low-density, dispersed suburbs, which are highly car dependent and resource and carbon emission intensive. This article develops a research agenda directed at determining and testing policy and planning measures relevant to the quest for low carbon mobility in New World cities. It suggests a rich agenda for essential research on LCM. Much of this agenda falls within the realm of the integration of transport and land use, with attention to urban design details to enhance the perceptions of and opportunities to use low carbon transport alternatives. Research topics identified for LCM research include (1) urban design and land use–transport integration (LUTI), (2) low carbon mobility policies directed at achieving widespread behavior change, (3) opportunities for new technology and its application, including requirements for systems and infrastructure, and (4) analysis and tools for informed decision making, including modeling, measurement, visualization, and especially assessment.     

Environmental scanning the future of event design

This paper used multiple sources of information in order to identify the forces likely to impact event design. Content analysis of key informant interviews and selected trade publication articles identified key forces impacting event design. Technology, the environment and green issues, security and safety, and globalization were forces identified by both the key informants and the trade literature. Neither of the sources gave much attention to political forces. This article contributes to our understanding of the forces impacting event design and suggests some environmental scanning methodologies that can be used with both key informants and the trade publication literature.

Effects of Picture Presentations on Customers' Behavioral Intentions on the Web

SUMMARY

As the Web is becoming a major communication channel to bridge hotels and customers, great marketing efforts have been made to attract new customers and repeat business. A wide variety of studies have been conducted to identify factors that could affect customers' purchase behavior on the Web. Little research, however, has been documented that assessed the effects different pictures presented on the Web had on customers' online purchase behavior. Based on the content analyses with 203 existing hotel Websites, this study examined the potential effects of Website format, Website contents, and Website realism on customers' behavioral intentions. Results indicate that the content and realism of picture presentations are important predictors of customers' attitudes toward the Website. The attitudes appear to be a strong predictor of behavioral intentions on the Web. Suggestions and implications are included for the lodging industry and future research.     

The impact of IT-enabled customer service systems on service personalization,customer service perceptions,and hotel performance

Customer service is a critical element of a hotel's strategy and an important lever for differentiation of the hotel's offer. Over the last two decades, information systems have contributed to the transformation of customer interactions, enabling an unprecedented scale and scope of service personalization in the tourism industry. This paper reports the results of a mixed method study in a hotel that offers three contributions to the development and refinement of IT-enabled service personalization theory. It explores the role of signifiers in the design of customer service systems, showing that they significantly increase customer preference elicitation during the learning phase of the service personalization process. It then demonstrates that improved preference elicitation translates into higher customer service evaluations and value perceptions of the hotel. Finally, our study shows that IT-enabled service personalization creates financial benefits for the hotel via revenue share-shift from costly intermediated to direct distribution channels.     

Value co-creation in sustainable tourism: A service-dominant logic approach

To mainstream sustainability, we need to understand the value gained from sustainability by users. We apply a user-centred design methodology to develop an agile, iterative, incremental and reflexive process to understand the sustainability value proposition for Lufthansa City Center travel agents. We analyse the failure of sustainability communications within the online platforms used by these agents and explore why the agents factor out sustainability information during the customer sales process. We identify how agents and customers understand sustainability, and we explore opportunities to co-create sustainability value. Furthermore, we prototype, and then test, methods of empowering travel agents to communicate sustainability to their customers as a value-adding proposition.
