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.     

A comparison of the dominant meta programme patterns in accounting undergraduate students and accounting lecturers at a UK business school

Meta programmes are a means of describing the behavioural traits that a person exhibits when interacting with other people. An understanding of meta programmes can improve communication between individuals and this may have implications for teaching. The purposes of this study are first to identify the dominant meta programme patterns of first year accounting undergraduates at a UK business school. An earlier pilot study validated use of the Motivation Profile Questionnaire (MPQ) to elicit the dominant meta programmes of accounting lecturers at the same Business School (Brown, 2002). Secondly, the students' meta programmes are compared with those of their accounting teachers to identify whether there are any differences or similarities between the two groups. The matching of the meta programmes of the teachers and students would enhance communication whilst major differences in meta programmes would make communication more difficult. A sample of 62 first year accounting undergraduates and 20 accountancy teachers completed the MPQ. The results indicate that, on average, the accounting students have similar dominant meta programme patterns to their accounting teachers. The implications of the findings for improving communication and therefore teaching are discussed, along with the scope for further research.

A theoretical framework of electronic word-of-mouth against the backdrop of social networking websites

This study proposed and tested a theoretical framework that explains electronic word-of-mouth (eWOM) against the backdrop of social networking websites (SNWs), which have gained substantial popularity among travelers. In particular, a United States (US) nationwide online survey was conducted and nine hypotheses were tested. The findings suggest that willingness to share knowledge and switching costs are positively related to eWOM communication. In addition, customer value (utilitarian) has positive relationships with willingness to share knowledge, perceived security, and switching cost, while customer value (hedonic) has positive relationships with willingness to share knowledge and switching costs. Last but not least, the findings indicate that perceived security does negatively impact eWOM. In light of the major findings, the article sets forth strategic implications for travel-related social networking websites.
