Using skin conductance and facial electromyography to measure emotional responses to tourism advertising

Although an objective and increasingly common technique in marketing, media and psychology, psychophysiological measures are rarely used in tourism research to detect tourism consumers’ spontaneous emotional responses. This study examines the use of psychophysiological measures in tourism and in particular explores the usefulness of skin conductance (SC) and facial electromyography (EMG) methods in tracking emotional responses to destination advertisements. Thirty-three participants were exposed to three destination advertisements while their self-report ratings, real-time SC and facial EMG data as well as post hoc interview data were obtained. The results demonstrate that, compared with self-report measures, psychophysiological measures are able to better distinguish between different destination advertisements, and between different dimensions of emotion. Participants’ affective experience reported in post hoc interviews was found to be consistent with emotional peaks identified from continuous facial EMG and SC monitoring. These results validate the ability of psychophysiological techniques to capture moment-to-moment emotional responses and it is concluded that psychophysiological methods are useful in measuring emotional responses to tourism advertising. Methodological insights regarding the constraints associated with the use and application of psychophysiological methods are discussed.

Dually sustainable urban mobility option: Shared-taxi operations with electric vehicles

Electric vehicles (EVs) are energy efficient and often presented as a zero-emission transport mode to achieve long-term decarbonization visions in the transport sector. The implementation of a sustainable transportation environment through EV utilization, however, requires the addressing of certain cost and environmental concerns such as limited driving range and battery-charging issues before its full potential can be realized. Nevertheless, a specific type of use of EVs, namely in taxi services, may elicit positive public opinion, as it promises a commitment toward sustainability in urban life. In light of this, this study proposes an integrated approach that combines EV operation with a conceptual design for shared-ride taxi services. As some productivity loss may be naturally expected due to the time spent in charging, it is important to look at whether such performance loss from the passenger and system standpoints can be offset with ingenuity in operational design. In this study, an EV taxi charge-replenishing scheme that can be coupled with a real-time taxi-dispatch algorithm is designed. The proposed EV charging schemes for taxi services are studied via simulations and the effects of the limited driving range and battery-charging details are examined from a system performance viewpoint. The simulation study also reveals illustrative results on the impact of the EV taxi fleet's operation on the charging system. Next, a real-time shared-taxi operation scheme that allows ride sharing with other passengers is proposed to maximize the operational efficiency. The simulation results suggest that the shared-taxi concept can be a viable option to improve on the limitations caused by EV operation. In addition, the importance of projected charging demands and queue delays at different charging locations are also addressed. Some limitations and a future research agenda are also discussed.
