PurposeThe purpose of this study is to focus on analyzing how the set of green intangibles held by wineries and their members, i.e. green intellectual capital (GIC), affects green innovation performance (GIP). Specifically, the study aims to investigate how GIP is influenced by GIC through the mediating role of the variable knowledge management (KM) and corporate social responsibility (CSR).Design/methodology/approachThe study proposes a conceptual model, based on previous studies, which is tested through structural equations (PLS-SEM) with data collected from 202 Spanish wineries.FindingsThe results of the research indicate that there is a positive and significant relationship between GIC and GIP. Furthermore, CSR and KM partially mediate the relationship between these two variables, playing a key role in the environmental management of wineries.Originality/valueThe present research, therefore, contributes to the literature in several ways. First, the study advances the understanding of GIC as well as its link with GIP. Second, the research aims to fill the gap in the literature through the study of CSR and KM as mediating variables in such a link. Third, to the best of the authors’ knowledge, the model proposed has not been previously addressed in the academic literature, thus representing an advance in scientific knowledge. Fourthly, no research has addressed the study of environmental intangibles in the wine industry, with this research, therefore, being a pioneer in contextualizing the study of GIC in this increasingly knowledge-intensive industry.

The purpose of this research is to analyze the effect of wine tourism activity on economic performance in the wine context of Ribera del Duero (Spain), as well as the mediating effect of ecological agriculture on this link. To this end, a conceptual model is proposed based on the literature review carried out and contrasted through structural equation modelling (PLS-SEM) with data from 263 wineries, which in turn represent the population under study. The study results allow for us to empirically demonstrate the positive and significant relationship of wine tourism on performance, as well as the partial mediation of ecological agriculture in this relationship. The study thus contributes to the academic literature in a remarkable way given that, to our knowledge, there are no previous studies that have addressed the mediating role of ecological agriculture in the wine tourism–economic performance link. However, the research also suffers from certain limitations. In particular, given the relevance of the study, it is necessary to broaden its geographical scope so that, as a future line of research, it is proposed to contextualize the model proposed in the California wine industry, being able to subsequently establish similarities and differences in the Old and New World.

The present research analyzes the different factors that influence the formation of green intellectual capital (GIC) in wine companies, contributing to the academic literature in a remarkable way, since, to the authors' knowledge, no research has been identified that addresses such typology of organizational intangibles in the wine industry. Through a case study, the research indicates that, from a green human capital (GHC) point of view, workers' knowledge derived from environmental awareness sessions or seminar attendance are key to enhance this set of intangibles. As for green structural capital (GSC), circular economy programs, carbon and water footprint measurement computer systems, and eco-efficient facilities are clear examples that enable the formation of this dimension of the GIC. Finally, the analysis of green relational capital (GRC) highlights the importance of the company-stakeholder link for the proper environmental management of the winery.

The aim of this research is to explore the positive effect of dynamic capabilities on firm performance in Spanish hotels to further expand the ongoing knowledge of management strategies in a dynamic environment. It also embraces novel issues by linking uncertain changes with the current literature on the COVID-19 crisis. This study also emphasizes the mediation effect of innovation capability as a key hotel strategy in today's world. The final sample is composed of 212 hotels in Spain. The results reveal a positive and significant influence of dynamic capabilities on hotel performance, which is mediated by innovation capability (partial mediation effect). Both theoretical and practical implication of this research can help navigate the economic consequences of the COVID-19 pandemic.

Firm managers play an important role in the implementation of corporate social responsibility (CSR) actions. Education is emerging as the key factor in developing a sense of moral responsibility amongst the business students who will eventually become company managers and decision makers. The aim of this research is, thus, twofold. First, to analyze the existence of a direct positive correlation between university students’ perception of CSR and its impact on business performance; and second, to examine the extent to which two factors (advantages brought by CSR and responsibilities toward stakeholders) act as mediation variables in the aforementioned correlation. The analysis was performed with a sample of 390 business‐related university students. Amongst the potential contributions made by this study we can highlight the possibility of knowing future managers’ way of thinking and of knowing the aspects where educational centers might improve their CSR teaching.

In this study, a flour from corn cob (central core of the maize ear, stage R4) was obtained through three treatments. The three flours obtained were characterized by bromatological analysis, yield, and granulometry. Additional dressing-type oil in water (O/W) emulsions were developed, varying the formulation by incorporating distinct amounts of corn cob flour. The formulations' stability was evaluated over a period of 21 days, determining the particle size, creaming index, coalescence rate, consistency coefficient (k), and flow behavior indices (n). Results have shown significant differences in protein, fat, and carbohydrate content in the flour, depending on the cooking treatment. A good percentage of grinding yield was obtained (98%), in addition to several fractions by granulometry (60, 120, 250 MESH), showing differences in their nutritional content. Finally, the particle size of O/W emulsions developed varied among formulations. The combination of 0.6% of xanthan gum (XG) and corn cob flour showed major stability in average droplet size. No significant differences were observed in the coalescence rate values for the three formulations. Still, significant differences in the creaming index were evidenced in those formulations without XG or corn cob flour. The results regarding the consistency coefficient (k) and flow behavior indices (n) suggest a possible synergy between XG and flour of corn cob for enhancing the viscosity and pseudoplasticity of dressings in a concentration-dependent manner.

Background: Parasitic infections represent one of the main public health problems in humans according to the WHO. Therefore, the need has arisen to find new treatments that can be used as an alternative cure to parasitosis. We aimed to investigate the in-vitro effects of the methanolic extract of Kalanchoe daigremontiana as well as its main component, quercetin against Entamoeba histolytica and Trichomonas vaginalis. Methods: For this purpose, the in-vitro activity of the methanol extract of K. daigremontiana also its main component, quercetin, against trophozoites of E. histolytica and T. vaginalis was evaluated, using the microassay technique. Furthermore, the antioxidant activity was determined. Finally, the cytotoxic and cytoprotective capacity was determined using the hemolysis technique. Results: The IC50 indicated that quercetin significantly (P < 0.05) inhibited the growth rate of the trophozoite stage of E. histolytica and T. vaginalis in comparison to the methanolic extract of K. daigremontiana (KalL). Also, quercetin significantly (P < 0.05) was a better antioxidant as compared with the positive control. In the evaluation of cytotoxicity effects, it could be observed that KalL as compared with quercetin exhibited more cytotoxicity against human erythrocytes. Quercetin significantly (P < 0.001) exhibited better cytoprotective activity compared to KalL. Conclusion: Both K. daigremontiana methanolic extract and quercetin alone demonstrated high antiparasitic activity against E. histolytica and T. vaginalis. However, the in-vivo efficacy of K. daigremontiana and quercetin also requires to be evaluated using an animal model.
