In a highly competitive scenario, such as today’s airline business, changes in the regulatory framework may produce important variations in the airlines’ results. An example is the introduction of Sustainable Aviation Fuel (SAF) mandates to help air transport decarbonization. The airlines’ break–even curve provides a useful tool to evaluate the competitive position among airlines and to assess and address the cost impact due to the new regulatory environment. The purpose of this paper is to evaluate the impact of new environmental regulations on airlines’ business results to achieve air transport decarbonization.

Based on the break–even curve and the relationship between fuel cost increment and fuel cost related to the airlines’ operating expenses, the unit cost increment due to SAF introduction is obtained for several scenarios of SAF prices and different airlines.

In many cases, we find that using 100% SAF with prices beyond 1.5 times the present fuel price generates losses: it is not feasible if it is not possible to transfer SAF price to passenger fares due to demand elasticity.

The novelty of this approach is the application of a rationale method to accurately determine the impact of several scenarios of SAF prices on airlines’ business results. This approach also provides a sound and compelling basis to argue before Environmental Regulation Authorities based on facts and figures. This paper is of use and value to airlines, the International Civil Aviation Organization (ICAO), the International Air Transport Association (IATA), practitioners and academics.

The study focused on the impact of microcredit on the short-term finances of microentrepreneurs at the Galerías Shopping Center in San Juan de Pasto, Colombia, from 2019 to 2023.

The design of the paper is empirical-analytical, focusing on the tangible and unique aspects of reality that can be fragmented for measurement. This approach privileges the use of data from the study population’s experience, which is treated analytically through statistics to establish frequencies and correlations between variables. The research involved a structured questionnaire based on bibliographic references and considering the operational framework of the variables, which underwent expert review, necessary adjustments, a pilot test and subsequent validation in 2019 and 2023. The reliability of the instrument was assessed using Cronbach’s alpha, ensuring a reliable indicator when equal to or greater than 0.7 in each analysis period. This methodology aimed to identify practices and how the financial profile influences short term.

The findings from the survey conducted with the microentrepreneurs at Galerías Shopping Center reveal several significant connections to the theoretical framework. The study revealed that many microentrepreneurs relied on their personal funds for business financing, indicating a limited understanding of financial principles. Additionally, a significant portion of microentrepreneurs mitigated investment risk by securing loans from financial institutions, yet none utilized government subsidies like entrepreneurship loans, pointing to a lack of advice. The findings underscore the importance of financial education and suitable financial services for business development.

One limitation of this study is the lack of detailed data on the financial structure of microentrepreneurs' businesses, as well as specific information on interest rates and the terms and conditions of the microcredit used. These limitations may affect the generalization of the results and the comprehensive understanding of the impact of microcredit on the short-term finances of microentrepreneurs. Future research could include a larger sample size and more accurate data on the financial structure of businesses, as well as a detailed investigation of interest rates and terms and conditions of microcredit, to provide a more comprehensive understanding of the financial impacts for microentrepreneurs.

The findings of this study have practical implications for microentrepreneurs in the Galerías Shopping Center. The research emphasizes the need for improved financial knowledge, accounting practices and debt management among microentrepreneurs. It also highlights the importance of financial education and access to suitable financial services for business development. The study’s insights can guide the development of training programs and initiatives aimed at enhancing financial literacy and financial management among microentrepreneurs, leading to more informed decision-making and improved financial outcomes.

From a social perspective, this research contributes to promoting economic development and financial inclusion. By addressing the mismanagement of microcredit by microentrepreneurs and providing insights into their short-term finances, the study aims to foster economic empowerment and sustainable development within communities. The findings underscore the significance of microfinance in driving economic growth, reducing poverty and promoting social inclusion. The research emphasizes the importance of equitable access to financial services, which can contribute to narrowing the gap between the financially excluded population and the conventional financial system.

This research adds originality and value to the academic community by addressing the incidence of microcredit on the short-term finances of microentrepreneurs in the specific context of the Galerías Shopping Center in San Juan de Pasto, Colombia. By characterizing the financial profile of microentrepreneurs, establishing the relationship between microcredit characteristics and the financial profile and proposing an action plan, the study provides valuable insights for decision-making in both the academic and microfinance fields. The research contributes to the existing literature on microfinance and financial inclusion, offering a unique perspective and potential solutions for optimizing the use of microcredit-funded resources by microentrepreneurs.

Age-difference in couple relationships in Mexico and Latin America has been a field of study predominantly approached by demographers and sociodemographers. In Western Europe and North America, the tendency is similar yet sociologists and anthropologists have contributed important knowledge to this discussion. The results of both groups of studies show that in most societies men marry and cohabitate with women younger than them and that in a rather small percentage women are older than men. The discussion on the reasons for which men prefer younger women or women prefer older men when marrying and cohabitating go from psychological to economic grounds. This study aims to contribute to the discussion on the reasons for which this pattern persists by study examining the narratives of 81 Mexican heterosexual men and women from three generations. This is done from a qualitative and sociological standpoint that approaches the age differences from the subjectivity and intimacy of the interviewees aiming to understand (i) the meanings of the age-gap and age discrepancy, (ii) the role of schooling and social class in the significance of the age-gap and age-discrepancy relationships, and (iii) the gender inequality in age-gap relationships. The data show that amid a vigorous and strong trend of unions between older men and younger women where great gender inequalities may persist, there are signs of cultural change that show the discomfort and stigma of such differences. This, rather than being a contradiction, reveals how schooling and social origin affect the resignification of the difference, and moreover, suggests that the power relations in the couple are more equitable.

The paper aims to identify the major research themes in consumer financial services between 2000 and 2020, their relative magnitude and interrelationship, to identify which themes have been most influential and to map the evolution of the field and identify emerging and under-researched themes that are promising for future research.

The core methodology is bibliometric analysis based on keyword co-occurrences. A total of 1,227 articles extracted from the Social Science Citation Index, Emerging Sources Citation Index and Scopus are used in the analysis. Key outputs of the SciMAT software are the research themes, and graphical outputs are called science mapping (evolution of the themes over time), strategic diagrams (visual representation of themes in a 2 × 2 grid) and cluster networks (themes and connected themes based on keyword co-occurrences).

The findings show that customer satisfaction, innovation, corporate social responsibility (CSR), Internet and consumer acceptance were the main so-called motor themes in the study period. Furthermore, five areas for further research are identified and discussed: Issues related to technology; marketing and consumer behavior; markets and industry; product and service development; and branding.

Bibliometric research allows the researcher to process large volumes of articles covering a broad scope, leading to rich and insightful results. However, for greater detail and nuance, the authors recommend supplementing the results of this study with a more focused and thorough qualitative literature review for each theme of interest.

Bibliometric analysis is under-used in management research. The authors are not aware of similar recent work in consumer financial services. The main value of this paper lies in knowledge dissemination to a wider audience (including practitioners and researchers in adjacent areas) and providing a rigorous platform for identifying future research opportunities.

This paper aims to explore the challenges and opportunities of blockchain technology adoption from the lens of the technological–organisational–environmental (TOE) framework for operational excellence in the UK automotive industry context.

The research methodology of this study follows a systematic review approach, which analyses existing academic published research papers in the top 35 academic journals. There was no specific timeframe established for this study and shortlisting the articles through a set of used keywords. A sample of 71 articles was shortlisted and analysed to provide a discussion on technological and management challenges and opportunities of blockchain adoption from the lens of the TOE framework for operational excellence.

The findings of this study present significant theoretical and managerial implications and deep understanding for firms seeking to understand the challenges and opportunities of blockchain adoption for their operational excellence.

The systematic literature approach was considered for the present study to explore existing academic papers on technological and management challenges and opportunities from the lens of TOE framework for operational excellence, whereas a more specified method meta-analysis can be considered for future research. The study has been explored in the UK automotive industry context, which has been considered as the limitation of generalisation across countries and industries.

This paper represents the most comprehensive literature study related to the technological and management challenges and opportunities of blockchain from the TOE framework angle for operational excellence.

This study aims to investigate the impact of I4.0 technologies and their interoperability on supply chains (SCs) performance and how the integration of such technologies and their interoperability can create pathways for SCs resilience post-COVID-19. This is of paramount importance in the context of COVID-19 as the investigation around I4.0 technologies may provide relevant insights on how SCs may better respond to unexpected situations like the current pandemic with the use of digital technologies.

A survey research method was designed based on some constructs extracted from the literature regarding the main disruptive technologies, interoperability, elements of supply chains processes (SCPs) performance such as integration, collaboration, transparency, efficiency, responsiveness and profitability. The data were collected from March to July 2020 from different regions of the world when the peak of the first wave of the pandemic had occurred. The survey resulted in 115 valid responses. The study used a combination of descriptive, correlation and multiple regression methods to analyse the data.

The study indicates that disruptive technologies significantly impact SCPs performance (integration, collaboration, responsiveness and transparency) and their resilience. The findings did not support the notion that these technologies improve the efficiency of SCs, a significant contrast to the existing literature. Our findings also refute the existing understanding that interoperability moderates the impact of disruptive technologies on SCPs performance and enhancing the resilience of SCs. However, the findings show that the integration of I4.0 technologies and their interoperability has a positive impact on SCPs profitability.

The findings strongly advocate that this integration plays an important role in improving SC performance, and a future pathway of SC resiliency post-COVID-19. Considering that the I4.0 trend will impact SCs in the coming years, this study brings a relevant contribution to researchers and practitioners.

This study makes a unique contribution by investigating a novel causal relationship between the main elements (I4.0 technologies, interoperability, processes performance and strategic outcomes) related to the SC in this new context.

This paper aims to focus on the evolution of nonprofit cultural institutions in Mexico and their relationship with Spain, regarding the four traditional elements of a marketing mix. Specifically, this paper examines marketing advancements in the digital environment, placing emphasis on the virtual exhibition Códices de México: Memorias y Saberes, as well as the marketing activities related to prehispanic and novohispanic codices between 2010 and 2022.

The first part of the present study provides a chronological framework based on the four components of a marketing mix, illustrating the transition of Mexican and Spanish public cultural institutions from their foundations to current times. It particularly provides insight into their recent accomplishments in the digital environment, underscoring potential networking areas. The second part offers an in-depth examination of the exhibition Códices de México: Memorias y Saberes (INAH 2015) and a review of digital sources from Mexican government entities to investigate marketing activities related to prehispanic and novohispanic codices.

Due to the historical approach used to document the transition of nonprofit cultural institutions in Mexico and Spain to the digital era, this article sheds lights on co-joint efforts in the digital marketing domain around prehispanic and novohispanic codices. Additionally, it illustrates the activities used by Mexican cultural institutions during the past two decades to disseminate knowledge on codices.

Regarding the methodological aspects of using historical resources through digital archives, this study solely comprised marketing activities reported in the records available on the official portal of cultural institutions.

This study argues for the utility of the four components rooted in a traditional marketing mix as a tool to illustrate the evolution of marketing practices within the cultural heritage domain. It also highlights the role played by cultural institutions in Mexico and Spain in the digital environment to strategically network around cultural heritage. Additionally, it sheds light on the implementation of methods for presenting Mexican codices grounded in virtual terrain.

This paper aims to evaluate the evolution of the organizational field in the Colombian coffee industry between 1960 and 2020 and explain how peripheral actors influenced institutional change.

The methods analyze historical processes from a hermeneutical and interpretative perspective. The authors used data collection techniques through interviews, archive data, publications and media reports, embracing an interdisciplinary and qualitative documentary approach. This approach helps the authors unravel the temporal dimensions of the historical discourse related to coffee and the involvement of various actors within organizational structures.

The authors found that, unlike the literature regarding the change in organizational fields, recently, within the coffee sector in Colombia, the institutional work of peripheral actors (small producers, local associative groups and coffee women, among others) is changing the field as follows: (1) women are changing traditional behaviors moving from hierarchical family structures and lack of gender awareness, to empowered, horizontal and sustained relationships, (2) indigenous people include rituals and other traditional practices in coffee production and (3) ex-guerrilla members are helping to strengthen the peace process implementation in Colombia through coffee production.

The authors did not conduct statistical or computational analysis to simulate the emergence of new organizational forms. Instead, the authors attempted to elucidate narratives and discourses that reflect the tensions between central and peripheral actors from a historical perspective.

This study seeks to help leaders and managers overcome processes or organizational change in which peripheral actors are crucial. From that perspective, allocating resources and capabilities can become more effective.

This paper offers a new perspective of change within organizational fields from the roles of peripheral actors, which are fundamental in change processes within organizational fields, especially in the global south, where tensions between elites and vulnerable people are familiar.

This study aims to examine the effectiveness (ad attitude, brand attitude and purchase intention) of celebrity endorsement in the form of explicit vs embedded advertising in the context of different new media (digital and social media).

An online experiment was conducted using a 2 (digital media vs social media) × 2 (explicit vs embedded celebrity endorsement) between-subjects design. Participants (n = 137) were exposed to a fictitious piece of online branded content using celebrity endorsement. Four experimental treatments were generated as the authors manipulated the new media and the explicitness of the celebrity endorsement in the ad piece.

The main result highlights that using social media (vs digital media) enhances celebrity endorsement's indirect influence on purchase intention via the serial mediating role of ad attitude and brand attitude, regardless of the explicitness of the message. In terms of the message format, no differences were observed.

The differential power of using celebrities across different new media to promote brands suggests the importance of interactivity in the context of celebrity endorsement. Additionally, the absence of differences in terms of message formats would show that the presence of the celebrity per se has a powerful effect.

Firms using new media to deliver their brand communication, including celebrity endorsements, can better understand the different capabilities of social media and digital media.

In the context in which empirical research equates new media with social media, this study provides an examination of celebrity endorsement assuming the complexity of the celebrity endorsement ion the current scenario: different types of new media and different types of message formats.

Este estudio tiene como objetivo examinar la efectividad (en términos de actitud a la pieza publicitaria, actitud hacia la marca e intención de compra) del celebrity endorsement en la forma de publicidad explícita versus incrustada en el contexto de diferentes tipos de nuevos medios (medios digitales y redes sociales).

Se llevó a cabo un experimento en línea utilizando un diseño between-subjects de 2 (medios digitales vs. redes sociales) × 2 (apoyo explícito vs. incrustado de celebridades). Los participantes (n = 137) fueron expuestos a una pieza online ficticia de contenido de marca en línea que utilizaba celebrity endorsement. Se generaron cuatro tratamientos experimentales, en los cuales los autores manipularon el uso de nuevos medios y el nivel de explicitación del celebrity endorsement en la pieza publicitaria.

Los resultados principales ponen de manifiesto que el uso de las redes sociales (vs. medios digitales) mejora la influencia indirecta del celebrity endorsement en la intención de compra a través del rol de mediación en serie de la actitud hacia la pieza publicitaria y la actitud hacia la marca, independientemente del nivel de explicitación del mensaje. En cuanto al formato del mensaje, no se observaron diferencias.

El poder diferencial del uso de celebridades en diferentes tipos de medios nuevos para promocionar marcas sugiere la importancia de la interactividad en el contexto del celebrity endorsement. Además, la ausencia de diferencias a nivel del formato del mensaje muestra que la presencia de la celebridad per se tiene un efecto relevante.

Según los resultados de los autores, las empresas que utilizan nuevos medios para su comunicación de marca, incluyendo celebrity endorsements, pueden comprender mejor las diferentes capacidades de las redes sociales y los medios digitales.

En un contexto donde la investigación empírica equipara los nuevos medios con las redes sociales, este estudio proporciona un examen del celebrity endorsement considerando la complejidad de la técnica en el actual escenario: diferentes tipos de nuevos medios y diferentes tipos de formatos de mensajes.
