This study investigates regional similarities and differences in the tourism research knowledge domain, based on two decades of publications. The authors analysed co-citations in the reference lists of full-length articles published in Annals of Tourism Research (1998–2017) in relation to four regions: North America, Europe, Asia, and the Pacific and Oceania. The findings reveal a degree of regional fragmentation in the tourism research knowledge domain. Several wide discourses characterize the scope of tourism knowledge: authenticity and the tourist experience, backpacker tourism, consumer behaviour, destination life cycle, tourism impacts and resident attitudes, paradigms, performance approach, and volunteer tourism. The authors document the contribution of each region to these discourses. Implications of regional distinctions are discussed along with future research opportunities. [ABSTRACT FROM AUTHOR]

Using the "Computers are social actors" paradigm, this study brings the concept of power to human–computer interactions in tourism. Building on theories of social power and deliberate practice, the authors examine psychological effects of expert power of online travel review platforms (influencer) and its interaction effects with the power of users (influenced). Two expert platform attributes are conceptualized: specialization and experience. A significant interaction effect was identified between platform specialization, platform experience, and user power on perceived information-task fit using a 2 × 2 × 2 between-subjects experiment. When users are powerful, specialization affected perceived information-task fit for low-experience platforms; no significant effect was evident for high experience platforms. When users are powerless, specialization did not affect perceived information-task fit, regardless of experience condition. Perceived information-task fit mediated the effect of specialization on intention to use. The findings contribute to power discourses by exploring the workings of expert power.

Using a mixed-method approach combining qualitative and quantitative review techniques, this study analyzed 86 articles to identify state-of-the-art thematic research trends and articulate knowledge domains in the smart tourism research. In particular, the thematic analysis identified 11 themes from the current smart tourism research. Results of the co-citation analysis identified and visualized four knowledge domains as the theoretical underpinning of existing smart tourism literature, thereby supplementing, and complementing the findings of the thematic analysis. The constituents of each theme and knowledge domain were discussed to reveal critical gaps and suggest future research directions. [ABSTRACT FROM AUTHOR]
