Abstract

Purpose

In this study, to investigate tourist mobility (i.e. hotel visits) during the COVID-19 pandemic, the authors developed three objectives with reference to protection motivation theory: (1) to examine changes in travel distances in the USA before and during the pandemic, (2) to identify distinct travel patterns across different regions during the pandemic; and (3) to explore threat- and coping-related factors influencing tourist mobility.

Design/methodology/approach

The authors used two primary sources of data. First, smartphone data from SafeGraph provided hotel-specific variables (e.g. location and visitor counts) and travel distances for 63,610 hotels in the USA. Second, state-level data representing various factors associated with travel distance were obtained from COVID-19 Data Hub and the US Census Bureau. The authors analyzed changes in travel distances over time at the state and regional levels and investigated clinical, policy and demographic factors associated with such changes.

Findings

The findings reveal actual travel movements and intraregional variances across different stages of the pandemic, as well as the roles of health-related policies and other externalities in shaping travel patterns amid public health risks.

Originality/value

To the best of the authors’ knowledge, this study is the first to empirically examine changes in travel distances to hotels as destinations using smartphone data along with state-level data on COVID-19 and demographics. The findings suggest that tourism enterprises and stakeholders can proactively adapt their strategies by considering threat appraisals and coping mechanisms, both of which are influenced by externalities such as health-related policies.

研究目的

在我们的研究中, 为了调查COVID-19大流行期间的旅游出行(例如:酒店访问), 我们根据保护动机理论制定了三个目标:(1)研究在COVID-19大流行前后美国的旅行距离的变化, (2)在大流行期间识别不同地区的不同旅行模式; 以及(3)探讨影响旅游出行的威胁和应对因素。

研究方法

我们利用了两个主要数据源。首先, 来自SafeGraph的智能手机数据提供了63,610家美国酒店的酒店特定变量(例如位置和访客计数)以及旅行距离数据。其次, 代表与旅行距离相关的各种因素的州级数据来自COVID-19数据中心和美国人口普查局。我们分析了州级和地区级的旅行距离随时间的变化, 并调查了与这些变化相关的临床、政策和人口因素。

研究发现

我们的研究结果揭示了不同阶段的实际旅行动态和地区内的差异, 以及在公共卫生风险中塑造旅行模式的健康相关政策和其他外部因素的作用。

研究创新

我们的研究是第一个利用智能手机数据以及与COVID-19和人口统计数据相关的州级数据, 经验性地研究了旅行距离到酒店作为目的地的变化。我们的研究结果表明, 旅游企业和利益相关者可以通过考虑威胁评估和应对机制来主动调整他们的策略, 这两者都受到健康相关政策等外部因素的影响。

Abstract

Purpose

The study aims to investigate the adoption of green certification programs by restaurants. More specifically, this study has three objectives: to examine the relationships between green certification program scores and customers’ perceptions, duration of green certification and green brand image and food-focused green practices and green brand image.

Design/methodology/approach

The authors collected 25,098 TripAdvisor reviews, along with associated patron demographics, for 70 green certified restaurants. To investigate the hypotheses, the authors first used structural topic modeling to discover latent themes relevant to green restaurant practices. Thereafter, the authors used factorial Multivariate analysis of covariance (MANCOVA) to examine the association between formal certification participation and customers’ green perceptions.

Findings

The results showed that customers were more likely to perceive a green restaurant image after visiting green certified restaurants with higher certification ratings and green certification periods of longer duration.

Practical implications

The current study contributes to the literature in several ways. First, this study uses post-visit online reviews written by customers of certified green restaurants to understand customers’ natural responses more precisely. Second, the study captures the degree of green commitment by applying information about formal certification programs, where other studies have relied on hypothetical scenarios or survey questions to examine the impact of green attributes on customer perceptions.

Originality/value

To the best of authors’ knowledge, this is the first study to investigate the adoption of green certification programs by restaurants empirically with data drawn from actual user-generated content (i.e. TripAdvisor).

Abstract

Purpose

This paper aims to showcase the trends in the research topics and their contributors over a time period of 30 years in the International Journal of Contemporary Hospitality Management (IJCHM). To be specific, this paper uncovers IJCHM’s latent topics and hidden patterns in published research and highlights the differences across three decades and before and after Social Sciences Citation indexing.

Design/methodology/approach

In total, 1,573 documents published over 199 issues of IJCHM were analyzed using two computational tools, i.e. metaknowledge and structural topic modeling (STM), as the basis of the mixed method. STM was used to discover the evolution of topics over time. Moreover, bibliometrics (and network analysis) were used to highlight IJCHM’s top researchers, top-cited references, the geographical networks of the researchers and differences in the collaborative networks.

Findings

The number of papers published continually increased over time with changes of key researchers publishing in IJCHM. The co-authorship networks have also changed and revealed an increasing diversity of authorship and collaborations among authors in different countries. Moreover, the variety of topics and the relative weight of each topic have also changed.

Research limitations/implications

Based on the findings of this study, theoretical and practical implications for hospitality and tourism researchers are provided.

Originality/value

It is the first attempt to apply topic modeling to a leading academic journal in hospitality and tourism and explore the diversity in contemporary hospitality management research (topics and contributors) from 30 years of published research.

Abstract

Purpose

The purpose of this study was to explore influences of review-related information on topical proportions and the pattern of word appearances in each topic (topical content) using structural topic model (STM).

Design/methodology/approach

For 173,607 Yelp.com reviews written in 2005-2016, STM-based topic modeling was applied with inclusion of covariates in addition to traditional statistical analyses.

Findings

Differences in topic prevalence and topical contents were found between certified green and non-certified restaurants. Customers’ recognition in sustainable food topics were changed over time.

Research limitations/implications

This study demonstrates the application of STM for the systematic analysis of a large amount of text data.

Originality/value

Limited study in the hospitality literature examined the influence of review-level metadata on topic and term estimation. Through topic modeling, customers’ natural responses toward green practices were identified.

Abstract

Purpose

This paper aims to identify the intellectual structure of four leading hospitality journals over 40 years by applying mixed-method approach, using both machine learning and traditional statistical analyses.

Design/methodology/approach

Abstracts from all 4,139 articles published in four top hospitality journals were analyzed using the structured topic modeling and inferential statistics. Topic correlation and community detection were applied to identify strengths of correlations and sub-groups of topics. Trend visualization and regression analysis were used to quantify the effects of the metadata (i.e. year of publication and journal) on topic proportions.

Findings

The authors found 50 topics and eight subgroups in the hospitality journals. Different evolutionary patterns in topic popularity were demonstrated, thereby providing the insights for popular research topics over time. The significant differences in topical proportions were found across the four leading hospitality journals, suggesting different foci in research topics in each journal.

Research limitations/implications

Combining machine learning techniques with traditional statistics demonstrated potential for discovering valuable insights from big text data in hospitality and tourism research contexts. The findings of this study may serve as a guide to understand the trends in the research field as well as the progress of specific areas or subfields.

Originality/value

It is the first attempt to apply topic modeling to academic publications and explore the effects of article metadata with the hospitality literature.
