Recommendation systems are a fundamental tool for hotels to adopt a differentiating competitive strategy. The main purpose of this work is to use machine learning techniques to treat imbalanced data sets, not applied until now in the tourism field. These techniques have allowed the authors to analyse the influence of imbalance data on hotel recommendation models and how this phenomenon affects client dissatisfaction.

An opinion survey was conducted among hotel customers of different categories in 120 different countries. A total of 135.102 surveys were collected over eleven quarters. A longitudinal design was conducted during this period. A binary logistic model was applied using the function generalized lineal model (GLM).

Through the analysis of a representative amount of data, the authors empirically demonstrate that the imbalance phenomenon is systematically present in hotel recommendation surveys. In addition, the authors show that the imbalance exists independently of the period in which the survey is done, which means that it is intrinsic to recommendation surveys on this topic. The authors demonstrate the improvement of recommendation systems highlighting the presence of imbalance data and consequences for marketing strategies.

The main contribution of the current work is to apply to the tourism sector the framework for imbalanced data, typically used in the machine learning, improving predictive models.

The heritage and tourist attractiveness of Heritage Cities have aroused interest in establishing mechanisms to enhance their value based on the development of sustainability policies. The socioeconomic and socioenvironmental valuation of these heritage sites has become a necessary tool for decision-making.

Following the recommendations of International Council on Monuments and Sites – ICOMOS, this paper proposes a series of indicators and an exploratory model to define the factors that contribute to their valuation. Following the partial least squares structural equation modelling methodology, information was obtained from 363 intramural residents in the three Heritage Cities that currently have management plans in Spain.

The results show the importance of specifying indicators of sustainable mobility and socioeconomic and socioenvironmental sustainability for an adequate valorisation of heritage sites.

To this end, it is necessary to follow the guidelines of international bodies such as ICOMOS in relation to the management plans.

The purpose of this study is to investigate the role of sales, as a proxy for size, in moderating the impact of institutional incongruence between formal and informal institutions on the formalization of microenterprises in middle-income countries in Latin America.

The paper uses a probit regression model to examine business formalization as a binary outcome of formal and informal institutions. Data was collected through interviews and surveys across 52 municipalities in the Metropolitan Region of Santiago, Chile. The study used a stratified sampling approach and was conducted between November 2022 and January 2023.

The results offer three key insights into the formalization of microenterprises in middle-income countries. First, we show that formal institutions do not significantly influence formalization decisions among microentrepreneurs in middle-income countries, challenging the traditional belief that formal institutions alone significantly influence formalization in these contexts. Second, we show that informal institutions are significant predictors of informality, especially among smaller microenterprises. Third, we highlight that the smaller the business, the stronger the negative effect of informal institutions on formalization, and thus, the institutional incongruence between formal and informal institutions decreases for larger businesses.

This paper contributes to management literature by shedding light on the drivers of formalization in middle-income countries, a departure from most formalization studies wherein the focus is primarily on low-income economies. The findings suggest that policymakers in middle-income countries should focus on enabling microenterprise growth through sales, rather than targeting specific demographic groups or relying solely on formal institutional enforcement to promote formalization.

El objetivo de este estudio es investigar el papel de las ventas, utilizadas como un indicador de tamaño, en la mediación del impacto de la incongruencia institucional entre instituciones formales e informales en la formalización de microempresas en países de ingresos medios en América Latina.

Utilizamos un modelo de regresión Probit para examinar la formalización empresarial como un resultado binario de instituciones formales e informales. Los datos se recopilaron a través de 110 entrevistas y encuestas en 52 municipios de la Región Metropolitana de Santiago, Chile. El estudio empleó un enfoque de muestreo estratificado y se llevó a cabo entre noviembre de 2022 y enero de 2023.

Nuestros resultados ofrecen tres ideas clave sobre la formalización de microempresas en países de ingresos medios. Primero, demostramos que las instituciones formales no influyen significativamente en las decisiones de formalización entre las microempresas en países de ingresos medios; esto desafía la creencia tradicional de que las instituciones formales por sí solas influyen significativamente en la formalización en estos contextos. Segundo, nuestro estudio muestra que las instituciones informales son predictores significativos de la informalidad, especialmente entre las microempresas más pequeñas. Tercero, nuestro estudio destaca que el efecto negativo de las instituciones informales sobre la formalización es más fuerte para negocios de menor tamaño; por lo tanto, la incongruencia institucional entre instituciones formales e informales disminuye para negocios de mayor tamaño.

Este artículo contribuye a la literatura iluminando sobre los impulsores de la formalización en países de ingresos medios, a diferencia de la mayoría de los estudios de formalización en la región latinoamericana que se centran principalmente en países de bajos ingresos. Nuestros hallazgos sugieren que los responsables de políticas en países de ingresos medios deberían centrarse en impulsar el crecimiento de las microempresas a través de las ventas, en lugar de enfocarse en grupos demográficos específicos o depender únicamente del cumplimiento institucional formal para promover la formalización.

Nossos resultados oferecem três ideias-chave sobre a formalização de microempresas em países de renda média. Primeiro, demonstramos que as instituições formais não influenciam significativamente as decisões de formalização entre as microempresas em países de renda média; isso desafia a crença tradicional de que as instituições formais, por si só, influenciam significativamente a formalização nesses contextos. Segundo, nosso estudo mostra que as instituições informais são preditores significativos da informalidade, especialmente entre as microempresas menores. Terceiro, nosso estudo destaca que o efeito negativo das instituições informais sobre a formalização é mais forte para negócios de menor porte; portanto, a incongruência institucional entre instituições formais e informais diminui para negócios de maior porte.

Este artigo contribui para a literatura iluminando os impulsionadores da formalização em países de renda média, ao contrário da maioria dos estudos de formalização na região latino-americana, que se concentram principalmente em países de baixa renda. Nossos achados sugerem que os responsáveis pelas políticas em países de renda média deveriam focar em impulsionar o crescimento das microempresas por meio das vendas, em vez de se concentrar em grupos demográficos específicos ou depender exclusivamente do cumprimento institucional formal para promover a formalização.

In this paper, the authors present an empirical framework that incorporates different factors of the impact of COVID-19 on small- and medium-sized enterprises (SMEs) in La Rioja, Spain, in relation to the value chain, gender and family business and allows the evaluation of these impacts on the SMEs' outcomes.

The authors conduct exploratory research based on phone interviews with 329 business managers from SMEs in La Rioja (Spain), from June 1 to June 30 2021, using ordinary least squares linear regression and matching procedures to test the study hypotheses.

The results show that the impact of COVID-19 related to primary activities in adding value, such as inbound logistics, operations and marketing, have a positive influence on innovation outcomes in SMEs, as do female managers. Family SMEs present poorer innovation outcomes.

At the organizational level, this paper may be of interest to management, and at the national and regional levels to policymakers, since it could help to develop policies that support SMEs' sourcing, operations and marketing in order to prepare for potential value chain disruptions. Additionally, this research may help decision-makers to foster and promote innovation in SMEs as a way of ensuring their resilience.

In this paper, the authors provide novel evidence about the effect of COVID-19 in SMEs. Moreover, it has been shown that the COVID-19 pandemic has triggered the redefinition of supply chains at the organizational level.

This paper analyzes how quality management in Ecuador’s national parks is explained through the quality practices contained in Deming’s quality principles from the point of view of employees.

Quantitative research was conducted with the participation of 254 employees from all national parks in Ecuador who rated the quality management practices (leadership, talent management, work climate and training) in their respective parks.

The results show that leadership, talent management, work climate and training significantly explain the service quality in the national parks. This study contributes to the adaptation of Deming’s quality principles to national parks via individual and joint analysis of the relationship between leadership, talent management, work climate and training with service quality in order to highlight which practices are the most important to service quality.

The paper provides a comprehensive overview of the key factors that influence service quality in the National Parks of Ecuador. Its multidisciplinary approach and exhaustive research make this work an invaluable tool for understanding and improving the preservation of natural resources and the tourism experience in these protected areas.

This study aims to focus on assessing the psychometric properties necessary to validate the internal structure of the TOURQUAL scale.

A quantitative research study was conducted in collaboration with the Brazilian Network of Tourism Observatories, comprising 927 respondents surveyed between October 2021 and May 2022. The data analysis involved the application of descriptive statistics and exploratory factor analysis, in alignment with the principles outlined in the Standards for Educational and Psychological Testing 2014 to validate the scale.

The findings of this study validate the TOURQUAL scale as a robust tool for assessing the perceived quality of tourist services, with results demonstrating one-dimensionality and replicability.

To the best of the authors’ knowledge, this study is the first to assess the psychometric properties for validating the internal structure of the TOURQUAL scale.

The purpose of this study is to critically review consumer knowledge in marketing and propose a future research agenda. Despite the many works that have examined this variable, given its strong influence on behaviour, it has generally been studied in association with other constructs, and no studies have focused on it in a specific way. Its definition, measurement and approaches to its role and usefulness are superficial and underdeveloped. After structuring and analysing the existing literature, the authors establish, (I) which aspects are of little use to the discipline, and (II) which research lines have the most potential and should be developed and studied in greater depth, to advance and complete the existing consumer knowledge framework.

A search was undertaken for documents in the main databases in which the term “consumer knowledge” appears in a marketing or consumer context, and a critical and reflexive approach was taken to analyse the main contributions and to structure them by content blocks.

Five main content blocks were identified. A set of research gaps were detected, mainly related to the lax conceptualisation of the topic, measurement problems and the scarcity of more useful works connected with business management, and several research lines are proposed that complement the existing framework to make it more complete and operational.

This paper offers a critical review and proposes a research agenda for one of the most used but little studied variables in the field of marketing, which may help academics and professionals in the discipline to continue developing useful theories and models.

El objetivo de este trabajo es revisar críticamente el conocimiento del consumidor en marketing y proponer una agenda de investigación futura. A pesar de los numerosos trabajos que han examinado esta variable, dada su fuerte influencia en el comportamiento, generalmente se ha estudiado en asociación con otros constructos, y ningún estudio se ha centrado en ella de manera específica. Su definición, medición y aproximaciones sobre su papel y utilidad son superficiales y poco desarrollados. Después de estructurar y analizar la literatura existente, establecemos (I) qué aspectos tienen poco uso para la disciplina y (II) qué líneas de investigación tienen más potencial y deben ser desarrolladas y estudiadas con mayor profundidad; para avanzar y completar el marco existente sobre conocimiento del consumidor.

Se realizó una búsqueda de documentos en las principales bases de datos en las que aparece el término “conocimiento del consumidor” en un contexto de marketing o consumo, y se adoptó un enfoque crítico y reflexivo para analizar las principales contribuciones y estructurarlas por bloques de contenido.

Se identificaron cinco bloques principales de contenido. Se detectó un conjunto de huecos de investigación, principalmente relacionados con la laxa conceptualización del tema, problemas de medición y la escasez de trabajos más útiles conectados con la gestión empresarial; y se proponen varias líneas de investigación que complementan el marco existente para hacerlo más completo y operativo.

Este documento ofrece una revisión crítica y propone una agenda de investigación para una de las variables más utilizadas pero poco estudiadas en el campo del marketing, lo que puede ayudar a académicos y profesionales en la disciplina a continuar desarrollando teorías y modelos útiles.

The authors originally explore the factors for blockchain technology (BCT) adoption in agricultural supply chains (ASCs) to enhance circularity and understand the dependencies, hierarchical structure and causalities between these factors.

Based on an extant literature review and expert opinion, the present study identified ten enablers for adopting BCT to leverage the circular economy (CE) practices in the ASCs. Then, using an integrated interpretive structural modeling and decision-making trial and evaluation laboratory (ISM-DEMATEL) approach, hierarchical and cause–effect relationships are established.

It was observed that traceability is the most prominent enabler from the CE perspective in ASCs. However, traceability, being a net effect enabler, will be realized through the achievement of other cause enablers, such as seamless connectivity and information flow and decentralized and distributed ledger technology. The authors also propose a 12 Rs framework for enhancing circularity in ASC operations.

The paper identifies enablers to BCT adoption that will enhance circularity in ASC operations. The ISM hierarchical model is based on the driving and dependence powers of the enablers, and DEMATEL aids in identifying causal relationships among the enablers.

The study's findings and proposed 12 Rs framework may help the practitioners and policymakers devise effective BCT implementation strategies in ASCs, thereby empowering sustainability and circularity.

This study enriches the literature by identifying and modeling enablers for BCT adoption in ASCs. The study also proposes a new 12 Rs framework to help enhance ASC circularity.

This study aims to describe and evaluate various visual and creative tools for supporting the in-depth biographical interview aimed at analyzing educational communities and their stakeholders.

Researching educational spaces today requires new ways of understanding, analyzing and studying. The complex characteristics, functions and realities demand research that responds to educational singularities. It is a matter of deeply understanding the educational phenomenon's peculiarities. For these purposes, instruments and research paradigms are needed to extract data and reach information saturation regarding the data obtained from the proposed objects of study. With this in mind, the following paper suggests reflecting on data collection tools that can complement the interview and biographical-narrative research approach. The authors highlight the use of photo-elucidation, the biogram-based timeline, the organigram and the flight of the geese, all of which are instruments endowed with a visual character that allows a deeper understanding of the object studied.

The main contribution of this paper is to unpack the uses and applications of four visual tools that support the interview technique. First, photo-elucidation is presented as a sensory strategy to stimulate the narrative during the dialogical exchange of the interview. Next, the timeline is described as a visual concretization of the traditional biogram widely used in educational research. Next, the authors unravel the uses of the organizational chart in educational research, which, due to its nature and utility, provides a glimpse of the organizational functioning of an institution and is particularly suitable for research in institutional frameworks. Finally, the tool known as the flight of the geese is presented. This tool is recommended for use in educational leadership and teamwork studies due to its simplicity and high representativeness of the hierarchy of roles and functions.

In the context of promoting sustainable development in SMEs, the present study aims to investigate the relationship among solution dimensions based on the Industry 4.0 (I4.0) concept.

The study employs a comprehensive methodology that includes a systematic literature review, workshop, grounded theory and interpretive structural modeling. Various dimensions concerning I4.0 sustainability are tested and evaluated using a questionnaire design followed by hypothesis formulation. Further, grounded theory is used to extract the key solution dimensions that capture the essence of I4.0 implementation in SMEs. Finally, the solution dimensions for I4.0 sustainability are modeled using the ISM approach to understand the structural interdependencies among them, and Matrice d'Impacts Croisés Multiplication Applied to a Classification (MICMAC) analysis is done to understand the driving and dependence power among these dimensions.

The study identified 14 solution dimensions for the implementation of I4.0 in SMEs for sustainable development. Out of the 14 solution dimensions, human resource training programs (D4) appear at level 11, followed by top management commitment (D1), strategic collaborations (D3) and coordination among key stakeholders (D5) at level 2 in the hierarchical interpretive structural modeling (ISM) model. Also, these dimensions have an effect size of more than 0.50 which indicates a substantial correlation between the sustainability dimensions and Industry 4.0 implementation in SMEs.

The study contributes to the overall goal of fostering sustainability within the SME sector, which can pave the way for various stakeholders for the successful implementation of I4.0 sustainable solution dimensions.
