The purpose of this paper is to identify the attitudes of Bulgarians towards country’s historical monuments, communist heritage, communist heritage tourism and their willingness to participate in communist heritage trips.

The sample includes 359 respondents recruited via an online survey. Mann-Whitney U-test is used to identify the differences in the respondents’ attitudes towards communist heritage tourism in Bulgaria on the basis of their age, gender, frequency of visit to historical monuments, attitudes towards country’s communist past, prior visit to, familiarity with and attitude towards communist monuments and identification of communist monuments with country’s heritage.

The respondents who visited historical monuments more frequently, had more positive attitudes towards communist past of the country and its communist monuments, those who had visited and were very familiar with the communist monuments were more supportive towards donating money for the restoration of communist monuments and their inclusion in tourism supply.

The paper reveals that domestic communist heritage tourism demand exists in Bulgaria and tour operators need to focus on including communist heritage in tourism supply.

Communist heritage is controversial and different social groups perceive it differently, depending on their attitudes towards communism as a political, economic and social system.

The paper compares the attitudes towards historical and communist monuments and revealed that communist monuments received less support for inclusion in tourism supply than historical monuments; the respondents were less inclined to participate in trips to them and to donate money for their restoration.

This paper aims to analyse three decision-making approaches that involve humans and artificial autonomous agents, namely, human “in the loop”, “on the loop” and “out of the loop” and identifies the decision characteristics that determine the choice of a decision-making approach.

This is a conceptual paper that analyses the relationships between the human and the artificial autonomous agents in the decision-making process from the perspectives of the agency theory, sustainability, legislation, economics and operations management.

The paper concludes that the human “out of the loop” approach is most suitable for quick, standardised, frequent decisions with low negative consequences of a wrong decision by the artificial intelligence taken within a well-defined context. Complex decisions with high outcome uncertainty that involve significant ethical issues require human participation in the form of a human “in the loop” or “on the loop” approach. Decisions that require high transparency need to be left to humans.

The paper evaluates the decision-making approaches from the perspectives of the agency theory, sustainability, legislation, economics and operations management and identifies the decision characteristics that determine the choice of a decision-making approach.

Artificial intelligence (AI) is increasingly becoming part of the hospitality industry. In times of staff shortages, AI used in the industry can have advantages, but it also brings with it the possibility of customer backlash. The purpose of this paper is to understand the potential response of millennial guests to the potential applications of AI in the hotel industry. The emphasis was on which hotel service encounter categories are most suited to replacing employees with AI in the context of the millennial guest experience.

This quantitative research used a survey questionnaire for the data collection. Responses from 169 millennials from six continents were analysed using a combination of descriptive statistics, t-tests, MANOVA tests and Bonferroni tests.

Four service encounter categories were studied: (i) “Check-in”, (ii) “Reception Services (excl. check-in)”, (iii) “Wellness” and (iv) “Food and Beverage Services”. The results showed that of these four categories, “Food and Beverage Services” is more suited to replacing employees with AI than “Wellness”.

The findings of this research are important as they contribute to the body of knowledge related to the implementation of AI in the hospitality industry and provide useful information to policymakers and hotel managers who may wish to identify suitable areas for investment related to AI in their operations.

This study offers useful insight on a cutting-edge topic of AI application for service encounters within the hospitality sector and confirms the suitability of some encounters.

The purpose of this perspective paper is to investigate the role of robots in tourism’s contribution to the achievement of the Sustainable Development Goals (SDGs).

With a deep analysis of the 17 SDGs and their 169 targets, the authors provide an interpretation on both the positive and negative impacts of robots in tourism towards the achievement of the SDG.

For several SDGs, the positive impact of robots in tourism is evident, whereas for others, it can be debated as the adoption of robots can lead to both positive and negative impacts, mostly dependent on how robots will be used. In particular, robots can provide a decent work environment for tourism and hospitality (TH) employees (SDG 8) who perform dangerous tasks while decreasing the consumption of resources (SDGs 2, 6, 7, 12, 13) due to their contribution to a company’s effectiveness and efficiency. In the meantime, robots have some impacts on the environment, both in terms of the use of resources (their manufacturing relies on rare Earth materials and robots are energy demanding) and output, especially for the management of toxic waste (e.g. batteries).

The main limitation of this perspective paper is the lack of empirical measurement of the effects of robots in tourism on the achievement of the SDGs. However, it is a necessary exploration as a foundation for future research.

This perspective paper may be useful for robot manufacturers in identifying the positive and negative aspects of robots when designing sustainable robots (in terms of energy efficiency, management of the end-of-life of components, etc.) to conform to the expectations of the SDGs. It can be useful to TH companies when their managers evaluate whether to adopt robots in service operations or not.

This contribution discusses the social implications in adopting robots in TH, specifically in terms of new opportunities for employment and in the substitution of humans in dirty, dull and dangerous tasks. It helps policymakers adopt the best policies for fostering the use of robots in TH with an eye to the environmental and social ramifications of robots.

To the best of the authors’ knowledge, this perspective paper is one of the first studies to investigate the role that robots can play in achieving the SDGs by TH companies.

本文旨在研究机器人在旅游业对实现永续发展目标(SDGs)的贡献。

从 17 个 SDGs及其 169 个目标深入分析后, 本文从正反两面向解释机器人在旅游业中对实现SDGs的影响。

机器人总体对旅游是有正面影响的, 但对少数SDGs可能衍生负面影响。机器人可为执行高风险任务的员工(SDGs)提供安全的工作环境, 也能因其效率使公司减少资源消耗(SDGs 2、6、7、12、13)。但无论在资源使用(制造仰赖土料及能源)或废弃物 (例电池)的管理, 机器人对环境有一定的风险。

本文是少数研究机器人在旅游和酒店业实现SDGs所扮演的角色。

本文缺乏旅游机器人对实现SDGs的实证测量, 但本研究可为未来研究奠定基础。

据SDG设计机器人时, 本文从能源效率和组件报废等角度, 为制造商点出机器人的正反面影响。当经理需评估是否在服务中采用机器人时, 本文也可提供方向。

本文在促进旅游和酒店业使用机器人的同时, 也讨论它们的社会影响, 特别是提供就业机会, 及代替高风险工作的员工。

El propósito de este artículo de perspectiva es investigar el papel de los robots en la contribución del turismo al logro de los Objetivos de Desarrollo Sostenible (ODS).

Los autores aportan una interpretación sobre los impactos, tanto positivos como negativos de los robots en el turismo hacia el logro de los ODS sobre un profundo análisis de los 17 ODS y sus 169 metas.

Para varios ODS, el impacto positivo de los robots en el turismo es evidente, mientras que para otros puede debatirse, ya que la adopción de robots puede generar impactos tanto positivos como negativos, dependiendo principalmente de cómo se utilicen. En particular, los robots pueden proporcionar un entorno de trabajo digno para los empleados de turismo y hostelería (ODS 8) que realizan tareas peligrosas, al tiempo que reducen el consumo de recursos (ODS 2, 6, 7, 12, 13) debido a su contribución a la eficacia y eficiencia de una empresa turística. De igual forma, los robots tienen algunos impactos en el medio ambiente, tanto en términos de uso de recursos (su fabricación se basa en materiales de tierras raras y los robots demandan energía) como de producción, especialmente para la gestión de desechos tóxicos (p. ej., baterías).

Este artículo de perspectiva es uno de los primeros estudios que investigan el papel que pueden desempeñar los robots en el logro de los ODS por parte de las empresas de turismo y hostelería.

La principal limitación de este artículo de perspectiva es la falta de medición empírica de los efectos de los robots en el turismo en el logro de los ODS. Sin embargo, es una exploración necesaria como base para futuras investigaciones.

Este artículo de perspectiva puede ser útil para que los fabricantes de robots identifiquen los aspectos positivos y negativos al diseñar robots sostenibles (en términos de eficiencia energética, gestión del final de la vida útil de los componentes, etc.) y así cumplir con las expectativas de los ODS. Puede ser útil para las empresas de turismo y hostelería cuando sus gerentes evalúan, si adoptar o no robots en las operaciones de servicio

Esta contribución discute las implicaciones sociales en la adopción de robots en el turismo y la hostelería, específicamente en términos de nuevas oportunidades de empleo, y en la sustitución de humanos en tareas rutinarias, aburridas o peligrosas. Ayuda a los responsables políticos a adoptar mejores políticas para fomentar el uso de robots en el turismo y la hostelería teniendo en cuenta las ramificaciones ambientales y sociales de éstos.

This chapter explores the strategic motives behind the decision of hotels to internationalize. It approaches the subject from the perspective of the soft-service sector and aims to develop an understanding of this phenomenon. The literature covers several different factors that stimulate the decision to expand operations abroad. The process requires a trigger that will initiate the process and control the assignment until completion. Eight semi-structured interviews were conducted with international hotel chains to develop an understanding of the process. The findings reveal factors that can be distinguished between proactive and reactive and also be categorized under the four major motives behind internationalization: seeking natural resources, markets, efficiency and strategic assets or capabilities. The international strategy of hotel chains provides a roadmap for expansion and often acts as a trigger. The findings also reveal the significant role of vice presidents (VPs) of international development, development directors, agents and networks in initiating the process of internationalization and stimulating the chains towards specific parts of the world. One of the main differences between manufacturing and soft services is the wide variety of entry modes that are at the disposal of services. The findings are consistent with the literature published and provide an insight into the initial steps towards internationalization by hotel chains, in the post-COVID era.

Research question: What are the strategic motives behind the decision of hotels to internationalize?

This chapter introduces the tourism–disaster–conflict nexus through a comprehensive review of the contemporary social science literature. After reviewing conceptual definitions of tourism, disaster and conflict, the chapter explores various axes that link through this nexus. The linkages between tourism and disaster include tourism as a trigger or amplifier of disasters, the impacts of disasters on the tourism industry, tourism as a driver of disaster recovery and disaster risk reduction strategies in the tourism sector. Linkages between tourism and conflict include the idea that tourism can be a force for peace and stability, the niche status of danger zone or dark heritage tourism, the concept of phoenix tourism in post-conflict destination rebranding, tourism and cultural conflicts, and tourism’s conflicts over land and resources. Linkages between disaster and conflict include disasters as triggers or intensifiers of civil conflict, disaster diplomacy and conflict resolution, disaster capitalism, and gender-based violence and intra-household conflict in the wake of disasters. These are some of the conversations that organise this volume, and this introductory chapter ends with a summary of the chapters that follow.

The purpose of this paper is to examine the shocks to firm's beta around the event of addition or deletion from the S&P 500 index.

The total derivative of beta and Campbell and Vuolteenaho decomposition of beta methodologies are used, on monthly and daily basis, to examine the behavior of beta around the event.

Results show a significant increase in correlations of the event firms' returns and the market proxy returns and cash‐flow betas, and decrease in discount‐rate betas for added firms and the opposite effects for deleted firms. Robustness tests indicate that the total derivative changes effects are typical for the event firms industry but that the cash‐flow correlation changes are specific to the firm. These findings suggest that addition or deletion from the S&P 500 index is not an information free event.

The Campbell and Vuolteenaho methodology has limitations – it is conditional on the selection of state variables. In future research it would be beneficial to use different state variables in the beta decomposition framework. Another relevant question for a future research is: what are the effects of the event on the Fama‐French factor model loadings?

The paper's findings contribute to the ongoing debate in the literature of the information hypothesis for addition or deletion from the S&P 500 index.

The present book chapter deals with the problem of dark tourism as well as the resilience forms of consumption in post-disaster context.

The turn of the century characterised a radical change in the forms of tourism consumption. New forms of tourism as dark or thana tourism have captivated the attention of scholars and journalists. This book chapter centres efforts in dillucidating what are the key factors that determine the formation of a dark site. The text is inspired in my own ethnographies in Cromañon, Argentina and the Ground Zero, US.

As Phillip Stone puts it, not all dark shrines or sites welcome tourists. While some sites are reluctant to mass tourism, others are mainly organised around the figure of the tourist. La Republica de Cromañón is a night club where in a fire died 194 young. The site is today refurbished as a sanctuary to remind the victims. At a closer look, there is a tension between stakeholders at the time of promoting dark tourism in Cromañón. In the opposite the ground zero is fully designed to be visited by thousands tourists.

The originality of this research consists in the contraposition of two study cases which answer the question to what extent dark tourism is desired by locals. The findings lay the foundations towards the specialised literature in dark tourism studies. We discuss critically the nature of thanatopsis.
