Despite the significant role that the visual plays in the experience of tourism, few studies have specifically examined the visual appearances of heritage tourist destinations. This study sought to analyze how historically grounded the visual appearances were of two heritage tourist towns in the state of Arizona: Tombstone and Jerome. These towns were both mining towns that experienced historic booms during the days of the American Old West and survive today as tourist destinations. This study utilized a detailed visual comparison of historic and contemporary town photographs in order to assess the relative historic-grounding of building exteriors and streets. It also incorporated the findings of interviews with tourists and town residents regarding their perceptions of visual historic-grounding. Study findings offered a means to assess and compare visual historic-grounding. Additionally, they suggested that while visual historic-grounding was important to visitors, it was one of several factors influencing their perceptions of the town's historic appearance: visual appeal, personal reflections, engaging activities, and previous visitor expectations of the American Old West (often grounded in filmic-representations) worked together to visually communicate a general impression of history within each town.  相似文献

ABSTRACT

Alumni communication is vital in sustaining the relationship between alumni and their alma maters. This research investigated four cohorts of alumni, and their intentions to use a range of traditional and digital communication channels, including social media. An online questionnaire was sent to 8060 alumni and resulted in 595 usable responses, yielding a 7% response rate. The research results showed that alumni have the highest intentions to use the alumni e-newsletter and the alumni Website and the lowest intentions to use social media, e.g., Twitter, Instagram, and YouTube. Among alumni cohorts, significant statistical differences in their intentions to use these communication channels were identified. Given our findings, alumni communication staff are encouraged to leverage different communication channels targeting alumni in different age groups.  相似文献

Although empowering employees has often been prescribed as an efficient strategy for hospitality organizations, the strategy alone cannot ensure success. Individual and organizational factors should be considered to increase employees’ perception of empowerment. This study examines the impact of employees’ customer orientation and organizational factors on the employee empowerment perceptions. Our findings, based on a survey of 203 guest contact employees, suggest that organizations should hire customer oriented people, guide them with service training, provide a reward system, and facilitate service standards communication in order to increase perceived empowerment. Implications of these findings for hospitality service managers are discussed.  相似文献

Great hopes have been placed in the sharing economy to provide a new business model based on peer-to-peer (P2P) exchanges of underutilized assets. As a model, the sharing economy has been expected to make significant contributions to sustainability, providing new opportunities for entrepreneurship, more sustainable use of resources, and consumer co-operation in tight economic networks. However, in recent years, digital platforms have turned into the most important actors in the global sharing economy, turning global corporations, such as AirBnB, Booking, or TripAdvisor into intermediaries controlling and profiting from most transactions. Focused on accommodation, this paper conceptualizes the sharing economy in comparison to the wider collaborative economy, and discusses its social, economic, environmental, and political impacts in comparison to the sustainable development goals. It concludes that the sharing economy has great potential to make very significant contributions to sustainability, though the model is increasingly being replaced by the collaborative economy, which performs as an extension and acceleration of neoliberal economic practices.  相似文献

In this editorial, we reflect on how the Journal of Sustainable Tourism can contribute towards sustainable tourism researchers achieving more impact with their research. We propose some changes that can be tested in, and introduced gradually and collaboratively with, the community of the editorial board and authors. To support impactful mind sets, we will promote research that reflects diverse academic communities. To promote impactful research topics, we will encourage authors to frame their submitted articles against the Sustainable Development Goals, while research that is time sensitive will be fast tracked so it can contribute to current debates. To promote impactful methodologies, we shall favour articles that use mixed methods and action research, and those that conduct longitudinal, experimental, and evaluative research. To promote impactful partnerships, we will favour multidisciplinary approaches and research that has been co-created with stakeholders. To promote impactful communication and dissemination, we will continue to build an online community on social media for sustainable tourism researchers, we will promote articles in social media to raise their visibility, and we will provide free access to those articles that are deemed to have the greatest potential to impact positively on society.  相似文献

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.  相似文献
