Psychological capital (PsyCap) has been identified as an individual’s positive psychological state of development that can help to reduce negative organizational outcomes. However, there is still a gap in understanding how PsyCap influences different aspects of organizations. This study investigates the mediating role of burnout in the relationship between PsyCap and turnover intentions among healthcare professionals. A cross-sectional survey was conducted among 320 healthcare professionals. The estimation of the relationships between PsyCap, burnout, and turnover intentions was obtained through structural equation modelling (SEM). A mediation analysis was carried out using bootstrapping procedures. The results show that burnout has a significant and positive effect on turnover intention and PsyCap has a significant and negative effect on burnout. Moreover, burnout fully mediates the relationship between PsyCap and turnover intention. These findings suggest that PsyCap can effectively reduce negative outcomes like burnout, but its positive impact may be limited when considering other outcomes such as turnover intention.

Eco-innovation has received a great deal of attention in academia and the business sector because it promotes a firm’s sustainable development and seeks to improve its performance. The prime objective of this study was to analyze the effect of the process, organization, and product eco-innovation on the company’s financial and environmental performance. Using a structural equation model estimated by maximum likelihood and a sample from 214 South American manufacturing companies in Colombia, Ecuador, and Perú, we found that organizational eco-innovation (OE) and process eco-innovation (PCE) are positively and significantly associated with the firm’s environmental and financial performance. In contrast, product eco-innovation (PDE) is not significantly associated with the two types of performance described. Likewise, OE has a significant and positive indirect influence on PDE, environmental performance, and financial performance. These findings suggest that OE and PCE positively affect the firm’s performance. On the contrary, PDE does not have this effect, extending the discussion that eco-innovation is specific to the context of the study.

Las intenciones emprendedoras han sido un tema estudiado con frecuencia por la comunidad científica. La literatura existente expresan argumentos variados, en el cual el tema central es como se determina la intención emprendedora. El presente estudio incluyó tres propósitos específicos. El primero fue explicar la incidencia de la proactividad en las intenciones emprendedoras en los estudiantes de pregrado; el segundo fue explicar la incidencia de la propensión al riesgo en las intenciones emprendedoras en los estudiantes de pregrado y el tercero fue explicar la incidencia de la autoeficacia en las intenciones emprendedoras en los estudiantes de pregrado. La recolección de datos fue realizada en ocho universidades ubicadas en las tres provincias de mayor población, importancia económica y número de estudiantes universitarios en el Ecuador. Mediante el análisis usando modelos de ecuaciones estructurales se demostró que la autoeficacia como factor reflectivo de segundo orden y la proactividad como factor reflectivo unidimensional, tienen una influencia significativa en la intención emprendedora de los estudiantes universitarios de Ecuador.

This paper sought to analyze the moderating effect of clean energy innovation on the relationship between corporate carbon footprint and corporate profits in fossil fuel intensive industrial sectors in which it is “hard to abate” CO₂e emissions. We used a longitudinal design consisting of a panel study with a structural equation modeling (SEM) method, based on partial least squares. For the analysis of longitudinal moderation, this paper employed a Bayesian multiple-indicator latent growth curve model (B-LGC model). A global sample was used, consisting of 7827 firm-year observations between 2015 and 2021 for 167 international firms. The results showed that the corporate carbon footprint had a very significant impact on corporate profits and that innovations in clean energy—measured as renewable energy consumption—positively moderate the relationship between Scope 3 value chain greenhouse gas emissions (according to the Greenhouse Gas (GHG) Protocol) and the gross profit margin obtained. In addition to the academic contributions made by the moderating effect of clean energy innovation, these findings imply that a more detailed understanding of total value chain emissions (Scope 3 CO₂e) among executives and managers at high CO₂e-emitting companies offers an effective mechanism for obtaining higher profits and creating competitive advantages, while at the same time achieving a net zero emissions strategy. More importantly, public policymakers will be able to use these results to revise CO₂e-related policies, paying closer attention to the Scope 3 CO₂e emissions produced by these companies to design regulatory and control mechanisms that stimulate clean energy innovation.

Esta investigación busca determinar la influencia de los estilos de liderazgo transaccional y transformacional en el comportamiento innovador. La investigación siguió un enfoque metodológico cuantitativo, de corte transversal, de alcance correlacional explicativo y con diseño no experimental. Se empleó una muestra de 386 cadetes de la Escuela Militar de Chorrillos Coronel Francisco Bolognesi (Perú). Los resultados se evaluaron mediante el modelamiento de ecuaciones estructurales utilizando mínimos cuadrados parciales. Se encontró que existe una influencia de los dos estilos de liderazgo estudiados sobre el comportamiento innovador de los cadetes. De acuerdo con la varianza explicada, el liderazgo transaccional explicaría el 22 % y el liderazgo transformacional, el 31 % de la variabilidad del comportamiento innovador. Esta investigación contribuye a comprender esta relación entre liderazgo y comportamiento innovador en el ámbito militar.
