Airline alliances represent examples of resource utilization across a network. This paper examines the need to distinguish between access to and mobilization of the resources held by allies. An ordinary least squares regression was applied to a sample from the Top International Airlines database. Our findings show that mobilization of the destinations of the partner companies through codeshare alliances has a positive and significant influence on the performance of airlines. Moreover, they suggest that the development of network resources mobilizing capability in increasingly dynamic and global environments will only generate an important source of competitive advantage when acted upon.

Boards of directors play important roles when responding to one of the biggest chal- lenges for companies today: environmental sustainability. Research has mainly been focused on the separate impacts of board structure, composition, and processes on corporate environmental performance. Understanding how these three dimensions of the board, which help to successfully fulfill the board roles, interact in complemen- tary or substitutive ways is crucial for improving companies' environmental perfor- mance. Using a fuzzy-set qualitative comparative analysis on a sample of 86 European-listed companies in greenhouse gas (GHG)-intensive sectors, our study shows that board dimensions and the attributes that shape them have complemen- tary or substitutable effects on corporate environmental performance. Specifically, we identified four board archetypes that arise from different configurations promot- ing environmental performance. Finally, we considered CEO-Board interaction, showing that both longer and shorter CEO tenures together with certain combina- tions of board attributes could be linked to higher environmental performance.

Este trabajo trata de avanzar en el estudio de las carteras de alianzas estratégicas aprovechando la potencialidad que ofrece el análisis de las redes sociales (ARS). En el estudio de las carteras de alianzas existen tres cuestiones principales de investigación que son: la emergencia, la configuración y la gestión de la cartera. Esta investigación se centra en la configuración de la cartera de alianzas, es decir, en el contenido y la estructura de la red egocéntrica del actor focal. Con este objetivo fueron analizadas 10.556 uniones temporales de empresas (UTE) realizadas por 229 empresas que desarrollan su actividad en el sector español de la construcción de obra pública. Los resultados muestran que las empresas analizadas siguen distintos comportamientos estratégicos a la hora de configurar sus carteras de alianzas
Does the Team Leverage the Board’s Decisions?
(Wiley, 2009) Barroso Castro, Carmen; Domínguez de la Concha-Castañeda, Marta; Vecino Gravel, Julio; Villegas Periñán, María del Mar; Universidad de Sevilla.

Research Question/Issue:This study analyses the form of the board-TMT interaction and the firm’s level of strategicchange. Relatedly, we explore the premise that there needs to be a good fit between the board of directors and the topmanagement team to effectively bring about strategic change.Research Findings/Insights:Using archival data from a sample of 119 firms in the period 1993–2000, we found that whena synergy exists between the board and the TMT, there will be a greater inclination for strategic change. The results indicatethat a board’s inclination to contribute to strategic change increases as the board size increases. Equally, it is possible toaccept that the relationship between board tenure and their inclination towards strategic change is not linear. Finally, thesimultaneous analysis of board composition and the ratio of directors on the TMT, demonstrates that the interaction of bothvariables has effects on the firm’s strategic change.Theoretical/Academic Implications:This study provides empirical support in favor of an active role of the board shapingthe firm’s strategic decisions. We have developed and tested a set of arguments regarding with the role of the board on thefirm’s change in strategy. We have investigated as well, the leveraging effect of one of the variables that define thecomposition of the management team on the relationship board-change in strategy.Practitioner/Policy Implications:In order to create an effective board, a broader governance structure must be examinedwith a detailed study of aspects of the composition of the board and the TMT (previous research has only consideredcharacteristics linked to the CEO). The dynamics of the relationships between both governance mechanisms are essentialand leverage the board capability.
Efficiency of automatic text generators for online review content generation

The evolution of Artificial Intelligence has led to the appearance of automatic text generators able to closely resemble human writing, endangering the development of e-commerce and the consumer confidence. Thus, it is critical to deeply understand how these text generators work to present the presence of deceptive reviews. This paper analyzes one of the most popular text generators, GPT2 (Generative Pre-trained Transformer 2), and studies its effectivity compared to human-generated reviews using previously published classifiers trained to distinguish between real and deceptive reviews. One parameter of the model is the so-called temperature, which determines how deterministic the model is. The temperature adjusts the probability distribution of the words in the model, so that a higher temperature translates into a higher degree of inventiveness in the generation of the texts. Findings reveal (i) that automatically-generated deceptive reviews worsen the accuracy of existing classifiers, this effect being accentuated by the degree of inventiveness; (ii) that their performance depends on the data used to train the generator; and (iii) that the sentiment polarity has no effect on the performance of detection classifiers.
Explanatory and predictive model of the adoptionof P2P payment systems
(Taylor and Francis, 2020) Lara Rubio, J.; Villarejo Ramos, Ángel Francisco; Liébana-Cabanillas, Francisco; Universidad de Sevilla. Departamento de Administración de Empresas y Comercialización e Investigación de Mercados (Marketing); Ministerio de Ciencia e Innovación (MICIN). España
The purpose of this paper is to identify the factors affecting the intention to use peer-to-peer (P2P)mobile payment. Although mobile technology has become part of everyday life, certain actions andservices, such as mobile payments, are still used relatively infrequently. In this paper, we analyseconsumers’adoption of P2P mobile payment services. Following a review of previous literaturein thisfield, we identify the main factors that determine the adoption of mobile payments, andthen perform a logistic regression (LR) analysis and propose a neural network to predict thisadoption. From the logistic regression results obtained we conclude that six variablessignificantly influence intentions to use P2P payment: ease of use, perceived risk, personalinnovativeness, perceived usefulness, subjective norms and perceived enjoyment. With respectto the nonparametric technique, wefind that the multilayer perceptrons (MLP) prediction modelfor the use of P2P payment obtains higher AUC values, and thus is more accurate, than the LRmodel. This paper is a pioneer study of intention to use with mobile payment using thesemethodologies. The outcome of this research has important implications for the theory andpractice of the adoption of P2P mobile payment services.
Exploración y explotación de los recursos de red y ciclo de vida
(Universitat Autònoma de Barcelona:egolab-GRAFO ; Universidad de Sevilla: LRPC, 2016) Gallego Agueda, María Ángeles; Cobeña Ruiz-Lopera, María del Mar; Casanueva Rocha, Cristóbal; Universidad de Sevilla.

La gestión de los recursos de red, entendidos como aquellos que son propiedad de los socios de una empresa y a los que accede a través de sus relaciones, es una cuestión básica en el desarrollo de alianzas y acuerdos. El tipo de recursos de red que serán necesarios para la empresa puede estar condicionado por el momento del ciclo de vida en que se encuentre y de si tiene una actitud de exploración o de explotación en el diseño y gestión de sus estrategias de cooperación. Se plantea una nueva consideración del ciclo de vida como un continuo entre empresas jóvenes y empresas consolidadas. Este trabajo analiza estas relaciones en el sector de las aerolíneas a nivel global. Los resultados muestran que las empresas consolidadas siguen simultáneamente un comportamiento de exploración y de explotación y que cuando se dan estos últimos se buscan recursos básicamente ligados al conocimiento y a la tecnología.
Network resources and social capital in airline alliance portfolios
(Elsevier, 2013) Casanueva Rocha, Cristóbal; Gallego Agueda, María Ángeles; Sancho Mejías, María; Universidad de Sevilla. Departamento de Administración de Empresas y Comercialización e Investigación de Mercados (Marketing); Ministerio de Ciencia e Innovación (MICIN). España
The airline sector is a mature industry in which a wide range of competitive practices reflect highly intense levels of rivalry. This is evident from the alliance portfolios of airline companies that are composed of mutually advantageous agreements between firms in the aviation sector. In this context, we examine the influence that access to valuable network resources may have on company performance (in operational and financial terms). Moreover, as network resources come under the resource dimension of a firm's social capital, we also study the way the resource dimension is affected by other dimensions of social capital (network position, network structure formed by the alliance portfolio and the quality of the relations). We study the alliances agreed between 214 mainstream airlines, up until 2007, during which time 351 airlines formed various types of partnerships. The results suggest, on the one hand, that access to partner resources is influenced by structural and relational factors. However, on the other hand, the structure of each airline's alliance portfolio has more influence than its position in the global network of alliances. These results point to the need for satisfactory governance of the composition and management of an airline's alliance portfolio.
Prediction and modelling online reviews helpfulness using 1D Convolutional Neural Networks
(Elsevier, 2022-07) Olmedilla, María; Martínez Torres, María del Rocío; Toral, S. L.; Universidad de Sevilla.

The latest research shows that the identification of helpful reviews from a large volume of user–generated data is a trending topic. The present study uses an approach that not only predicts if an online review is helpful, neutral or not helpful with 66% accuracy, but most importantly models online review helpfulness. To this end, we use an adaptive implementation of 1D Convolutional Neural Networks (CNNs). The neuronal encoding of CNNs has the benefit of obtaining automatic data classification using cluster analysis to detect different types of clusters of helpful and not helpful reviews, categorized by their most important contextual characteristics. Findings reveal that the clusters with the most important words and documents for helpful reviews in the product category ‘Cars & Motorcycles’ describe cars and their characteristics, whereas not helpful reviews concern details about car-related shops/companies in general. By demonstrating high performance on prediction and classification of review helpfulness with our proposed methodology, we are contributing to the research on business intelligence. In addition, we provide significant practical implications for marketers, enabling them to distinguish between helpful and not helpful reviews. Using the resulting encoding can produce automatic data classification of different clusters of specific topics.
Social capital configuration and the contingent value of the cross-national diversity: a multi-group analysis
(Elsevier, 2015) Castro Abancens, Ignacio; Acedo González, Francisco José; Picón Berjoyo, Araceli; Universidad de Sevilla. Departamento de Administración de Empresas y Comercialización e Investigación de Mercados (Marketing); Ministerio de Ciencia e Innovación (MICIN). España
The present paper attempts take an in-depth look into the configuration of social capital as a multidimensional construct, and unlike other studies,the dimensions are interrelated, and all ofthis in a global inter-organizational context. This work also analyses the influence of the cross-national diversity of corporate governance on the configuration of social capital. A variance-based structural equation modelling (partial least squares) and the multi-group analysis have been applied to a sample consisting of 225 global contractors. The findings lead us to argue that the different dimensions of social capital configuration do not act independently, but they exert a certain effect among themselves, and also affect the international market share of the company. Furthermore, the way each company configures the dimensions of social capital dimensions will depend on the company’s corporate governance style.
Speed of the internationalisation process. The role of objective vs. subjective perceptions of time
(Springer, 2024) Casillas Bueno, José Carlos; Moreno Menéndez, Ana María; Acedo González, Francisco José; Ramos Hidalgo, María Encarnación; Universidad de Sevilla. Departamento de Administración de Empresas y Comercialización e Investigación de Mercados (Marketing); Ministerio de Ciencia e Innovación (MICIN). España
Time is often neglected as a factor in international business research. In this paper, objective and subjective perspectives of time are incorporated into the study of speed of a firm's internationalisation process. The concept of speed is defined as the relationship between distance and time, and therefore we propose a theoretical framework that applies these two perspectives of time both to distance and to time, and differentiate between three levels of analysis: individual, organisational, and environmental. Our framework also incorporates two mediating constructs: learning speed and risk perception. Ten hypotheses are proposed that contribute towards a better understanding of the temporal dimension of the internationalisation process.
