As public health professionals strive to promote vaccines for inoculation efforts, fervent anti-vaccination movements are marshaling against it. This study is motived by a need to better understand the online discussion around vaccination. The authors identified the sentiments, emotions and topics of pro- and anti-vaxxers’ tweets, investigated their change since the pandemic started and further examined the associations between these content features and audiences’ engagement.

Utilizing a snowball sampling method, data were collected from the Twitter accounts of 100 pro-vaxxers (266,680 tweets) and 100 anti-vaxxers (248,425 tweets). The authors are adopting a zero-shot machine learning algorithm with a pre-trained transformer-based model for sentiment analysis and structural topic modeling to extract the topics. And the authors use the hurdle negative binomial model to test the relationships among sentiment/emotion, topics and engagement.

In general, pro-vaxxers used more positive tones and more emotions of joy in their tweets, while anti-vaxxers utilized more negative terms. The cues of sadness predominantly encourage retweets across the pro- and anti-vaccine corpus, while tweets amplifying the emotion of surprise are more attention-grabbing and getting more likes. Topic modeling of tweets yields the top 15 topics for pro- and anti-vaxxers separately. Among the pro-vaxxers’ tweets, the topics of “Child protection” and “COVID-19 situation” are positively predicting audiences’ engagement. For anti-vaxxers, the topics of “Supporting Trump,” “Injured children,” “COVID-19 situation,” “Media propaganda” and “Community building” are more appealing to audiences.

This study utilizes social media data and a state-of-art machine learning algorithm to generate insights into the development of emotionally appealing content and effective vaccine promotion strategies while combating coronavirus disease 2019 and moving toward a global recovery.

Sustainable development goals (SDGs) are gaining significant importance in the current environment. Many businesses are keen to adopt SDGs to get a competitive edge. There are certain challenges in realigning the present working scenario for sustainable development, which is a primary concern for society. Various firms are adopting sustainable engineering (SE) practices to tackle such issues. Artificial intelligence (AI) is an emerging technology that can help the ineffective adoption of sustainable practices in an uncertain environment. In this regard, there is a need to review the current research practices in the field of SE in AI. The purpose of the present study is to comprehensive review the research trend in the field of SE in AI.

This work presents a review of AI applications in SE for decision-making in an uncertain environment. SCOPUS database was considered for shortlisting the articles. Specific keywords on AI, SE and decision-making were given, and a total of 127 articles were shortlisted after implying inclusion and exclusion criteria.

Bibliometric study and network analyses were performed to analyse the current research trends and to see the research collaboration between researchers and countries. Emerging research themes were identified by using structural topic modelling (STM) and were discussed further.

Research propositions corresponding to each research theme were presented for future research directions. Finally, the implications of the study were discussed.

This work presents a systematic review of articles in the field of AI applications in SE with the help of bibliometric study, network analyses and STM.

To investigate whether additional information of the permanent news flow, especially reporting intensity, can help to increase transparency in housing markets, this study aims to examine the relationship between news coverage or news sentiment and residential real estate prices in Germany at a regional level.

Using methods in the field of natural language processing, in particular word embeddings and dictionary-based sentiment analyses, the authors derive five different sentiment measures from almost 320,000 news articles of two professional German real estate news providers. These sentiment indicators are used as covariates in a first difference fixed effects regression to investigate the relationship between news coverage or news sentiment and residential real estate prices.

The empirical results suggest that the ascertained news-based indicators have a significant positive relationship with residential real estate prices. It appears that the combination of news coverage and news sentiment proves to be a reliable indicator. Furthermore, the extracted sentiment measures lead residential real estate prices up to two quarters. Finally, the explanatory power increases when regressing on prices for condominiums compared with houses, implying that the indicators may rather reflect investor sentiment.

To the best of the authors’ knowledge, this is the first paper to extract both the news coverage and news sentiment from real estate-related news for regional German housing markets. The approach presented in this study to quantify additional qualitative data from texts is replicable and can be applied to many further research areas on real estate topics.

This study aims to investigate the relationship between consumer awareness of Zespri International Limited (Zespri™) and its sales promotion in Japan and the recent expansion of New Zealand (NZ) kiwifruit imported into Japan.

Tweets mentioning Zespri™ were utilised as a proxy of such awareness. They were first summarised using two text-mining techniques: tf-idf scoring and a co-occurrence network graph. Afterwards, the authors estimated a tri-variate vector autoregression (VAR) model consisting of the net imports of NZ kiwifruit in Japan, unit import price and number of tweets. Additionally, the occurrence frequency of tweets with “Kiwi Brothers”, promotional characters for Zespri™’s sales, was added to the model, and a tetra-variate VAR model was estimated. Finally, Granger-causality tests, an estimation of the impulse response function and forecast error variance decomposition was conducted.

All these variables were found to Granger-cause each other. Furthermore, a shock in the document frequency of “Kiwi Brothers” significantly affected Japan’s kiwifruit imports from NZ, explaining approximately 20% of future imports. Zespri™’s distinctive sales promotion was, thus, found to contribute in part to the recent increase in NZ’s kiwifruit export to Japan.

This paper is the first to apply text-regression methodology to food consumption research; it contributes to food consumption research by proposing a practical way to combine tweets with outcome variables using a time-series analysis.

The appraisal of corporate reputation based on third-party corporate social responsibility (CSR) indices appears to have been institutionalized. The endorsement of such an approach by sustainability custodians and influencers undermines the uptake of the morality and legitimacy of CSR. This study takes a social realist perspective, which suggests that social phenomena such as CSR and corporate reputation are shaped by social structures and power relations. This study aims to contribute to a deeper understanding of the complex relationship between CSR and corporate reputation and understand ways in which the constructs are influenced by cognitive factors.

This study surveyed 411 respondents across five shopping malls and analyzed the data using path analysis of the structural equation modeling (SEM) technique. The mall-intercept survey sought to critically assess expectations of CSR vis-à-vis evaluation of corporate reputation. Based on a case study of three Johannesburg Stock Exchange listed companies, CSR expectations were measured along the philanthropic, economic, ethical and legal dimensions, while evaluation of corporate reputation was based on product quality, financial performance and social responsibility. SEM path analysis was used to extrapolate the predictive outcomes of CSR on corporate reputation.

Reputation for product quality and social responsibility is underpinned by the fulfillment of ethical CSR expectations, while philanthropic gestures enhance the evaluation of financial performance. Legal CSR significantly influences the reputation for social responsibility and product quality. Fulfillment of economic CSR expectations influences the reputation for product quality. However, no relationship was established between economic performance and social responsibility. Involvement in economic, philanthropic and particularly, legal CSR, are not indicative of the reputation for financial performance. Conversely, companies’ involvement in economic CSR does not suggest a higher propensity for social responsibility.

The predictive outcomes of CSR expectations on corporate reputation can reveal situated understanding of actual perceptions of corporate behavior.

Ethical business conduct is synonymously associated with social responsibility while espoused corporate philanthropy signals strong financial performance. The awareness of consumers’ cognitive evaluation of corporate reputation can offer a pathway to corporate communication professionals, policy makers and agencies to rethink and reposition CSR efforts.

Insensitivity to taken-for-granted cultural prescriptions and reliance on market-based reputational rankings undermine mutually beneficial stakeholder relationships and the social license to operate.

This study brings to the fore, cognitively dominated indicators of consumers’ perceptions of the reputation for CSR, to foster nuanced and halo-removed approaches to social responsibility. The authors show for the first time how companies’ skewed focus on corporate philanthropic giving paradoxically signals a capitalistic notion of social responsibility and unethical business conduct. This study offers a halo-removed orientation to the appraisal of CSR and corporate reputation.

The user experience during the use of activities and services is a fundamental aspect for sports managers and can provide a competitive advantage. The purpose of this study was to identify the dimensions of experiential quality and the relationship of this construct with customer trust and customer satisfaction in achieving behavioral intention.

Using a convenience sampling technique, a total of 322 gym users in Turkey participated. A two-step approach was used to test both the model and the research hypotheses [confirmatory factor analysis (CFA) and structural equation modeling (SEM)].

The interaction quality, physical environmental quality, outcome quality and enjoyment quality were positively related to experiential quality. Similarly, the experimental quality was positively related to customer satisfaction and customer trust. Finally, customer satisfaction was related to behavioral intentions.

This study provides empirical evidence about the importance of experiential quality to gain a competitive advantage in the context of fitness centers.

Little is known about Indonesian consumers' acceptance of global brands despite their huge retail market potential. Drawing from Festinger’s (1957) cognitive dissonance theory and Schwartz’s (1992) value system, this study aims to examine the effect of Indonesian consumers' religiosity, cosmopolitanism and ethnocentrism on their preference for and purchase intention towards global brands.

Data were collected from 316 female consumers aged 20 years or older living in Indonesia via a professional online survey firm. The firm sent prospective participants an email invitation with a survey URL. Confirmatory factor analysis and structural equation modelling were conducted using AMOS 24.0 to test hypotheses.

The analyses revealed that Indonesian consumers' religiosity increased their ethnocentrism but not cosmopolitanism. Further, ethnocentrism decreased global brand preference without affecting purchase intention towards Korean cosmetics, whereas cosmopolitanism increased both global brand preference and purchase intention towards Korean cosmetics.

The findings show that cosmopolitanism has a stronger influence on global brand preference than ethnocentrism, suggesting ethnocentrism’s diminishing relevance in predicting purchase intention for foreign products. Additionally, religiosity’s effect on ethnocentrism was confirmed.

The purpose of this study is to analyze state-of-the-art knowledge of artificial intelligence (AI) research in hospitality.

This study adopts the theory-context-methods framework to systematically review 100 AI-related articles recently published (i.e. from 2021 to April 2023) in three top-tier hospitality journals, namely, the International Journal of Contemporary Hospitality Management, International Journal of Hospitality Management and Journal of Hospitality Marketing and Management.

Findings suggest that studies of AI applications in hospitality are mostly theory-driven, whereas most AI methods research adopts a data-driven approach. State-of-the-art AI applications research exhibits the most interest in service robots. In AI methods research, little attention was paid to the amid-service/experience.

This study reveals inadequacies in theory, context and methods in contemporary AI research. More research from hospitality suppliers’ perspectives and research on generative AI applications are advocated in response to the unveiled research gaps and recent AI developments.

This study classifies the most recent AI research in hospitality into two main streams – AI applications research and AI methods research – and discusses the gaps in each research stream and latest AI developments. The paper then suggests future research directions to guide researchers in advancing AI research in hospitality.
