In view of the increasing popularity of online reviews and their significant impact on individual buying behavior as well as on the supply side, this study reviewed and analyzed articles related to online reviews in tourism and hospitality published in academic journals between 2004 and 2013. Based on a keyword-driven search and a content analysis, 50 articles were identified as relevant and classified into five topics. The findings revealed that (a) more than half of the analyzed articles focus on hotels and apply empirical methods based on secondary data, (b) more attention has been paid to the relationship between online reviews and online buying as well as satisfaction and online management, and (c) opinion mining of online reviews, motivation to post reviews, and the role of reviews are evenly distributed. This paper also discussed significant topical and methodological trends, contributes to an overall understanding of existing research and its limitation.

Mountain regions and peripheral communities, which often depend on few economic sectors, are among the most exposed and sensitive to climate change. Governance of such socio-economic-ecological networks plays a strong role in determining their resilience. Social processes of governance, such as collaboration between communities, can be systematically assessed through the existence and strength of connections between actors and their embeddedness in the broader socio-economic network by social network analysis (SNA). This paper examines how network governance of the tourism industry-dependent Swiss Gotthard region relates to resilience to climate change by SNA. The paper argues that economic diversification and a network structure supporting stability, flexibility, and innovation increase regional resilience to climate change. The Gotthard network has a high diversification capability due to high cohesion and close collaboration, limited innovative capacity by the existence of only two subgroups, and considerable flexibility through the centralized structure. Main weaknesses are a low density, uneven distribution of power, and a lack of integration of some supply chain sectors into the overall network.

Purpose This study aims to empirically test a research model investigating the effects of authentic leadership (AL) and transformational leadership (TL) on follower service innovation behavior (SIB) with follower psychological capital (PsyCap) as a partial mediator. Design/methodology/approach Using data from a sample of 336 full-time frontline employees across 15 five-star hotels in Seoul, South Korea, over a time lag of one month, hypothesized relationships were analyzed with structural equation modeling. Findings The results suggest that AL has a greater effect on follower PsyCap and SIB than TL. In examining the role of PsyCap as a partial mediator, the results support the hypotheses that AL and TL trigger follower SIB directly but at the same time boost follower PsyCap, thus enhancing follower SIB. Practical implications The greater impact of AL on follower PsyCap and SIB suggests that the practice of corporate human resource management should place an emphasis on AL traits in leadership development. This study offers a useful perspective on the development of follower PsyCap and SIB by linking leadership traits. Originality/value By discussing AL and TL together within a single research framework, the study extends organizational psychology research by linking TL and AL to two important organizational psychological and performance variables, and exploring their comparative effects.
