The purpose of this paper is to describe numerical investigations focused on the reduction of separation and the aerodynamic enhancement of wind turbine blades by a rod vortex generator (RVG).

A flow modelling approach through the use of a Reynolds-averaged Navier–Stokes solver is used. The numerical tools are validated with experimental data for the NREL Phase VI rotor and the S809 aerofoil. The effect of rod vortex generator’s (RVG) configuration on aerofoil aerodynamic performance, flow structure and separation is analysed. RVGs’ chordwise locations and spanwise distance are considered, and the optimum configuration of the RVG is applied to the wind turbine rotor.

Results show that streamwise vortices created by RVGs lead to modification of flow structure in boundary layer. As a result, the implementation of RVGs on aerofoil has proven to decrease the flow separation and enhance the aerodynamic performance of aerofoils. The effect on flow structure and aerodynamic performance has shown to be dependent on dimensions, chordwise location and spanwise distribution of rods. The implementation of devices with the optimum configuration has shown to increase aerodynamic performance and to significantly reduce separation for selected conditions. Application of rods to the wind turbine rotor has proven to avoid the spanwise penetration of flow separation where applied, leading to reduction of flow separation and to aerodynamic enhancement.

The proposed RVGs have shown potential to enhance the aerodynamic performance of wind turbine rotors and profiles, making devices an alternative solution to the classical vortex generators for wind turbine applications.

This paper aims to identify the effect of environmental management systems (EMSs), commitment to stakeholders and gender diversity on corporate environmental performance (CEP) and the extent to which an economic crisis moderates these relationships.

A regression analysis was conducted on a sample of 14,217 observations from 1,933 firms from 26 countries from 2002 to 2010. The estimator used is ordinary least squares with heteroscedastic panel-corrected standard errors (PCSEs), which allows us to obtain consistent results in the presence of heteroscedasticity and autocorrelation.

The results show that EMSs and stakeholder engagement are mechanisms that drive CEP but lose their effectiveness in times of crisis. However, the presence of women on boards has a positive effect on CEP that is not affected by an economic crisis.

The study has some limitations that could be addressed in the future. We present board gender diversity as a governance mechanism because its role is strongly related to non-financial performance. Future studies could focus on other corporate governance mechanisms, such as the presence of institutional or long-term investors. In addition, other mechanisms could be found that can counteract poor environmental performance in times of crisis. Finally, it might be useful to contrast these results with the crisis generated by the coronavirus pandemic.

The results obtained have important practical implications at the corporate and institutional levels. At the corporate level, they highlight, as essential contributions, that environmental management systems and stakeholder orientation are not effective in times of economic crisis, except for with the presence of women on the board.

Following the crisis, the European Commission has promoted gender diversity on boards as a mechanism to improve the governance of entities – improving, among other aspects, sustainability. In this sense, another one of the practical implications of the study is support for the policies that the European Union has implemented over the last two decades.

The paper analyses how a crisis affects the moral and cultural institutional mechanisms that promote CEP. Gender diversity on the board of directors not only promotes environmental performance but also appears to be a governance mechanism that ensures this performance in times of crisis when the other mechanisms lose their effectiveness. The study proposes specific policies that help maintain environmental performance in an economic crisis.

This research aims to explore the influence of the wine tourism development on the sustainable competitive advantage of Spanish wineries as well as the role of employee well-being and organizational commitment on this main relationship.

This research formulates a theoretical model and then examines it through structural equation modeling. The analysis is based on data collected from 196 wineries in Spain, compiled during the period from September 2022 to January 2023.

The results of this study show a positive and significant effect between the wine tourism development and the sustainable competitive advantage of wineries in Spain as well as the mediating role of employee well-being and organizational commitment in this main connection.

Based on the study’s findings, winery managers are advised to develop wine tourism strategies that include guided tours emphasizing sustainability, curated food and wine experiences, cultural activities and specialized employee training programs to improve service quality, strengthen organizational commitment, and eventually achieve a sustainable competitive advantage.

The distinctiveness of this research stems from various key aspects: first, it enhances insight into the benefits linked to the wine tourism research field; second, this is the inaugural study to explore wine tourism development as a driving force for sustainable competitive advantage within Spanish wineries and; third, prior studies have not concurrently examined the functions of employee well-being and organizational commitment in mediating the connection between wine tourism development and the wineries’ sustainable competitive advantage.

The purpose of this study is to analyze the effect of wine tourism on the economic, social and environmental performance, i.e. the sustainable performance, of Spanish wineries. In addition, age, size and membership in the protected designation of origin are introduced as control variables to increase the precision of the cause-effect relationships analyzed.

A conceptual model is proposed, which is tested by means of structural equation modeling based on data from a survey of 202 Spanish wineries.

The results indicate the existence of a positive and significant link between wine tourism activities and the three performance typologies analyzed in the Spanish wine context.

The study contributes to the academic literature on wine tourism in a remarkable way, as, to the best of the authors’ knowledge, there is no previous literature that has addressed the effect of wine tourism on the sustainable performance of Spanish wineries, making the study useful for both academics and wine professionals who are considering the implementation or development of this typology of tourism in their facilities.

The research focuses on analysing the effect of wine tourism (WT) on the green performance (GP) of Spanish wineries, as well as the mediating role of green intellectual capital (GIC) and the moderating effect of circular economy practices (CEPs) developed by wineries in this main relationship. In addition, age, size and protected designation of origin (PDO) membership are introduced as control variables to increase the precision of the cause–effect relationships analysed.

A conceptual model is proposed through the literature review carried out and then verified through structural equation modelling (PLS-SEM) based on data obtained from a survey of 202 Spanish wineries between September 2021 and January 2022.

The results of the study show that WT activity has a positive and significant effect on the GP of wineries, also demonstrating the mediating effect of GIC and the moderating role of CEPs in this relationship.

The study contributes to the academic literature in several ways. First, to the best of our knowledge, no previous study has addressed the impact of WT on the set of wineries' ecological intangibles. Second, to the authors’ knowledge, no previous study has analysed the mediating effect of GIC on the WT-GP relationship. Third, there is no previous attempt to deal with the moderating role of CEPs in the main relationship under analysis. Fourth, the proposed theoretical model has not been previously addressed in the academic literature.

A captivating journey through Spain's verdant vineyards is unveiled in this study, where the burgeoning realm of wine tourism is revolutionising the wine industry from within. At the heart of this evolution lies Bodegas Franco-Españolas, where the fusion of wine culture, gastronomy and authenticity is being explored as a transformative force for sustainable and innovative practices. Through the lens of qualitative research, the myriad ways in which wine tourism acts as a catalyst for economic, social and environmental enrichment within the winemaking domain are revealed. This exploration transcends academic boundaries, offering a narrative of transformation that provides actionable insights and strategic frameworks for industry leaders and policymakers. The essence of wine tourism is being embraced, charting a course towards a future where the wine industry not only thrives but does so sustainably and innovatively. A toast is raised to a new era of wine tourism, where each glass poured signifies a step towards a greener, more vibrant viticultural landscape.

The purpose of this paper is to attempt to understand the extent to which price consciousness and quality consciousness influence attitudinal loyalty to store brands (SBs) in different segments of consumers: heavy, medium and light buyers of SBs. SBs are currently consolidated among price-conscious consumers, but less established among the quality-conscious consumers.

After reviewing the literature and constructing a theoretical model, the authors performed a study on Spanish food products, a sector in which SBs have achieved a significant market share. They collected data through a personal survey and analyzed it using structural equations modeling, and they performed a multigroup analysis of heavy buyers, medium buyers and light buyers of SBs.

The results obtained alert retailers to the tremendous importance of price vs quality in the formation of SB value and loyalty to SBs among heavy buyers of these brands, show the balance between price and quality as components of SB value and generators of loyalty among medium buyers and recognize the need to strengthen the image of SB quality to reinforce SBs’ value and smart shopping associations to increase light buyers’ loyalty to SBs.

The study contributes new evidence and knowledge on SB loyalty among consumers who show different usage of these brands (heavy, medium and light buyers). It then assesses the short- and long-term value of each segment of customers for the retailer and recommends retail strategies adapted to each segment.

This research focuses on analysing the effect of wine tourism on green product and process innovations developed by Spanish wineries. In addition, age, size and membership in a protected designation of origin (PDO) are introduced as control variables to increase the precision of the cause–effect relationship analysed.

The study proposes a conceptual model based on previous studies, which is tested using structural equations (partial least squares structural equation modelling [PLS-SEM]) with data collected from 202 Spanish wineries.

The research results show that wine tourism activity has a positive and significant influence on green product and process innovation.

The research contributes to the academic literature in several ways. First, the study advances knowledge and understanding of the benefits generated by wine tourism. Second, the research contributes to the literature that analyses the wine tourism–sustainability link, since it is predicted that this type of tourism can increase the capacity for green innovation. Third, to the best of the authors’ knowledge, there is no previous research that has analysed wine tourism as a catalytic variable for green innovation. Fourth, the proposed theoretical model has not been previously addressed in the academic literature, so the study represents an important advance in scientific knowledge.

The research aims to analyze the effect of corporate social responsibility (CSR) on sustainable performance (SP), as well as the mediating effect of organizational commitment (OC) and consumer satisfaction (CS) on this link. In addition, the variables age, size and membership of a Protected Designation of Origin (PDO) are included as control variables to increase the precision of the cause–effect relationships under study.

A theoretical model is formulated to achieve the proposed research objectives, which is then tested by structural equation modeling (PLS-SEM) on the basis of primary data obtained from a survey of 196 Spanish wineries between September 2022 and January 2023.

The findings of the research show that CSR has a positive and significant effect on the SP of wineries, demonstrating also the mediating effect of OC and CS in this link.

There are several reasons that justify the originality of this study. First, the present research advances the knowledge and understanding of the meaning of the CSR–SP relationship of wineries. Secondly, to our knowledge, there are no previous studies that have analyzed OC and CS as measurement variables in the CSR–SP link in the wine context, so the study provides new scientific knowledge. Thirdly, to the best of our knowledge, the proposed theoretical model has not been previously tested, so the study advances the academic literature and management decisions on CSR and sustainability.

The objective of this study focuses on the characterization of the Latin American entrepreneurial profile from a psychological perspective. In order to do this, a journey through time was carried out in the study of the entrepreneurial subject, from the great classics to the contemporary era, the era of knowledge, innovation, technology, and revolution. In the Latin American context, the role of the entrepreneur is limited due to vulnerable institutions, corruption, populism, and socioeconomic inequity. However, the new information and communication technologies constitute an ideal route for growth in the region. The fundamental element is the psychological profile of the entrepreneur, which is made up of a set of personal characteristics, among which innovation, achievement motivation, self-efficacy, moderate propensity for risk, creativity, perseverance, proactivity, flexibility, locus of control stand out, internal, adaptability, responsibility, ability to recognize opportunities, autonomy, commitment, handling problems and managerial skills. Finally, case studies from countries such as Mexico, Peru, and Chile are presented. It is a documentary study which reflects that Latin American entrepreneurs share the same psychological attributes as those who live in developed countries. However, obstacles arising from the lack of environment and public policies are imposed on entrepreneurial activity. The culture of a country and the formative role of education can become limiting or enhancing factors; therefore, it is necessary to bet on beliefs and convictions attached to innovation, which strengthen the psychological attributes of the entrepreneurial spirit.
