AbstractThis study examined the effects of the Big Five personality traits on support/strain exchange within older couples. Data of 1,775 older couples aged between 50 and 85 years in 2014 from the Health and Retirement Study were assessed, and actor–partner interdependent models were used. For the actor effects, all the five factors predicted their report on the spousal support/strain from the spouse; some differences between husbands and wives, as well as support and strain, were detected. For the partner effects, conscientiousness, agreeableness, and neuroticism predicted the support/strain provision reported by the partner. The findings of this study illustrate that certain personality factors work as predictors of spousal support/strain in older couples. The possible mechanism with regard to older adults' personality and marital relationship was discussed.

PurposeThis research focuses on analyzing the impact of Green Intellectual Capital (GIC) on the Environmental Performance (EP) of Spanish wineries, as well as the mediating effect of Green Ambidexterity Innovation (GAI) on the main relationship posed (GIC–EP), and the moderating effect of Top Management Environmental Awareness (TMEA) on the GAI–EP link. In addition, age, size and size and membership in a Protected Designation of Origin (PDO) to increase the accuracy of the cause–effect relationships examined.Design/methodology/approachThe study proposes a conceptual model based on previous studies, which is tested using structural equations (PLS-SEM) with data collected from 196 Spanish wineries between September 2022 and January 2023.FindingsThe results of the research reveal the existence of a positive and significant relationship between the development of GIC and EP of Spanish wineries, as well as the partial mediation of GAI in this link and the positive moderation of TMEA in the GAI–EP relationship.Originality/valueThe originality of the study is explained by several factors. First, the study pioneered the exploration of TMEA as a moderator of the relationship between GAI and EP, allowing such analysis to improve understanding of the dynamic interaction between innovation and environmental management. Second, to the best of the authors' knowledge, there are no preceding studies that have previously proposed the theoretical model presented in this research, thus providing new scientific knowledge on the intellectual capital field. Third, the contextualization of the study in the wine sector, traditionally perceived as little knowledge-intensive, contributes significantly to the existing body of scientific knowledge on the environmental management of wineries, given that it allows the identification of the catalysing variables of EP in the Spanish wine context.
