How do tourism goal disclosure motivations drive Chinese tourists\u27 goal-directed behaviors? The influences of feedback valence, affective rumination, and emotional engagement

Based on self-determination theory and the broaden-and-build theory of positive emotion, this study investigated the motivations of disclosing tourism goals on social media and its impacts on Chinese tourists\u27 goal-directed behaviors (GDBs). We proposed and tested a mutual transformation model of tourism goal disclosure motivation under different conditions of feedback valence (positive vs. negative feedback) and examine the mediating role of tourists\u27 affective rumination and emotional engagement. The results revealed that tourists driven by extrinsic motivations develop a stronger emotional engagement in their tourism goals and exhibit more GDBs after receiving positive feedback on their disclosed tourism goals. However, negative feedback disclosed goals lowers GDBs and leads to affective rumination about tourism goals among those with intrinsic motivations. This study provides theoretical and practical implications for destination marketers to adopt marketing strategies based on the findings

Giant Gating Tunability of Optical Refractive Index in Transition Metal Dichalcogenide Monolayers

We report that the refractive index of transition metal dichacolgenide (TMDC) monolayers, such as MoS2, WS2, and WSe2, can be substantially tuned by > 60% in the imaginary part and > 20% in the real part around exciton resonances using CMOS-compatible electrical gating. This giant tunablility is rooted in the dominance of excitonic effects in the refractive index of the monolayers and the strong susceptibility of the excitons to the influence of injected charge carriers. The tunability mainly results from the effects of injected charge carriers to broaden the spectral width of excitonic interband transitions and to facilitate the interconversion of neutral and charged excitons. The other effects of the injected charge carriers, such as renormalizing bandgap and changing exciton binding energy, only play negligible roles. We also demonstrate that the atomically thin monolayers, when combined with photonic structures, can enable the efficiencies of optical absorption (reflection) tuned from 40% (60%) to 80% (20%) due to the giant tunability of refractive index. This work may pave the way towards the development of field-effect photonics in which the optical functionality can be controlled with CMOS circuits

Gradient estimates for positive weak solution to Δpu+auσ=0\Delta_pu+au^{\sigma}=0 on Riemannian manifolds

In this paper, we study gradient estimates for positive weak solutions to the following $p$-Laplacian equation $$\Delta_pu+au^{\sigma}=0$$ on a Riemannian manifold, where $p>1$ and $a,\sigma$ are two nonzero real constants. By virtue of the Morser iteration technique, we derive some gradient estimates, which show that when the Ricci curvature is nonnegative, the above equation does not admit positive weak solutions under some scopes of $p$.Comment: All comments are welcom

The influence of tourists\u27 monetary and temporal sunk costs on destination trust and visit intention

Although the phenomenon of sunk costs is common in tourism situations, tourism research has largely ignored its effect on tourists. Drawing on prospect theory, cognitive dissonance theory, and signal theory, this study proposed that monetary sunk cost and temporal sunk cost both have significant impact on potential tourists\u27 visit intention. Four scenario-based experiments were performed to test hypothesized relationships. Findings revealed that monetary sunk cost has a negative effect on visit intention, while temporal sunk cost has a positive effect. Good destination reputation attenuates the effects, and destination trust mediates the relationship between sunk cost and visit intention. These studies extend existing theoretical applications by identifying the conditions under which sunk cost can influence tourists\u27 visit intention, and provides relevant practical suggestions for tourism product suppliers and local government departments

How do destination negative events trigger tourists’ perceived betrayal and boycott? The moderating role of relationship quality

This study presented and tested a conceptual model that examined how a negative event at a tourism destination influenced perceived betrayal and boycott among tourists. A mixed method approach with three studies was adopted to verify the proposed hypotheses. In Study 1, using Weibo microblogging platform data, we evaluated the impacts of a negative event on tourists\u27 perception of betrayal and intentions to participate in a tourism boycott. In Study 2, an experimental study was conducted to investigate the relationships among the negative event, perceptions of betrayal, and propensity for a tourism boycott. In Study 3, an additional experimental study revealed that relationship quality would moderate the influences of negative events on perceptions of betrayal and intention to join a boycott. The findings of this study offer theoretical and managerial implications for destination management organizations’ responses to negative events

How does destination crisis event type impact tourist emotion and forgiveness? The moderating role of destination crisis history

Drawing on attribution theory and situational crisis communication theory, this study investigates how destination crisis events impact tourist sympathy, anger, and intentions of forgiveness in four experiments. It also examines the moderating effects of destination crisis history (none vs. similar vs. dissimilar). The results of Study 1 and Study 2 revealed that external crisis events cause more sympathy and tourist forgiveness than internal ones, but less anger. They also indicated that sympathy and anger play a mediating role in destination crisis events and tourist forgiveness. The results of Study 3 and Study 4 revealed that destination crisis history predicts the impact of crisis events on tourist emotion and forgiveness. In particular, when there is no destination crisis history or similar crisis history, an external crisis event will garner more sympathy and forgiveness than an internal crisis event. These findings provide theoretical and practical implications for destination crisis management

How does destination social responsibility contribute to environmentally responsible behaviour? A destination resident perspective

Based on stakeholder theory and social exchange theory, this study developed an integrated model to demonstrate that destination social responsibility (DSR) influences tourism impacts (both positive and negative impacts), overall community satisfaction, and both directly and indirectly influences resident environmentally responsible behaviour (ERB). The model was examined using a sample of 453 residents living on the Gulangyu Island, a famous island tourism destination of Xiamen, China. Results show that DSR enhances residents’ perception of positive tourism impacts, improves overall community satisfaction and contributes to resident ERB. However, the effect of DSR on negative tourism impacts was not significant. Thus, positive tourism impacts and overall community satisfaction partially mediated the effect of DSR on resident ERB. The study findings offer both theoretical insights and practical implications on destination management and sustainable destination development
