In the contemporary organizational context, sustainability has expanded beyond ecological concerns to include the psychological and social wellbeing of employees. Emotional Intelligence, defined as the ability to perceive, understand, regulate, and utilize emotions constructively, has gained prominence as a critical determinant of sustainable organizational practices. This study investigate the role of EI in shaping employee wellbeing and sustainable workplace behavior, with a particular focus on how emotional competencies contribute to resilience, collaboration, and alignment with organizational values. Drawing on Goleman's 5-component model of EI: self-awareness, self-regulation, motivation, empathy, and social skills—this research develops and validates a conceptual framework that links EI to workplace sustainability outcomes. A quantitative, cross-sectional design was employed, and data were collected from 200 full-time employees working in both public and private sectors in Karnataka, India. Using a structured questionnaire, measures were obtained for Emotional Intelligence, employee wellbeing, and sustainability-oriented behaviors. The analysis was conducted using SPSS v25 and the PROCESS macro to test direct and mediating effects. Results demonstrated that EI significantly predicts employee wellbeing (β = 0.68, p < 0.001), and both constructs show strong positive associations with sustainable workplace behavior (β = 0.63, p < 0.001). Mediation analysis further revealed that employee wellbeing partially mediates the relationship between EI and sustainable behavior, indicating that wellbeing enhances but does not fully explain the impact of EI on workplace sustainability. The findings highlights the pivotal role of emotional competencies in promoting not only psychological safety and workplace harmony but also behaviors aligned with organizational sustainability and the United Nations Sustainable Development Goals (SDGs). This study advances the discourse on "human sustainability" by integrating emotional intelligence with sustainable organizational practices, an area that remains underexplored in existing literature. Practical implications include the need for HR managers and policymakers to design EI-based training, employee wellness programs, and emotionally supportive leadership interventions as strategies for building resilient, future-ready workplaces. By establishing a direct and indirect pathway between EI, employee wellbeing, and sustainable workplace behavior, this research contributes to both theory and practice. It underscores the potential of EI as a strategic lever for achieving sustainable growth through enhanced human capital.

This work examines the influence of activation energy, magnetic field (MF), and quadratic thermal radiation (Q-TR) on the stagnation-point flow generated by an off-centered rotating disk (O-CRD) subjected to Soret and Dufour effects (S-DE). Furthermore, the governing partial differential equations (PDEs) are transformed into ordinary differential equations (ODEs) using suitable similarity variables. Additionally, the numerical solutions are obtained for reduced ODEs using the Runge–Kutta–Fehlberg fourth-fifth order (RKF-45) technique. Furthermore, the response surface methodology (RSM) is utilized to assess the heat transportation rate of the fluid flow. The impact of non-dimensional parameters on the liquid profiles is shown graphically. The results indicate that the MF parameter decreases fluid velocity, whereas an increase in the rotational parameter increases the flow near the disk. An increase in the Soret number enhances the concentration profile. The temperature profile enhances as the radiation parameter intensifies. These results provide a better understanding of complicated transport processes, which help to develop and improve engineering systems that utilize high-temperature rotating machinery, chemical processing, and sophisticated thermal management.

Hybrid nanofluid has gained a lot of attention from researchers in the current generation of fluid technology because of its potential and thermal characteristics, which improve the rate of heat transfer more effectively than nanofluid. Applications for hybrid nanofluids in engineering, industrial, and medical research include biological disciplines, drug, and cooling operations. Therefore, the current study examines the mass and heat transfer in Boger hybrid nanofluid circulation across a moving flat plate while accounting for linear thermal radiation and nonlinear thermal radiation with the Blasius and Sakiadis flows. The magnetic field and chemical reaction impacts are also considered. By utilizing an appropriate similarity transformation, the collection of PDEs (partial differential equations) are modified into ODEs (ordinary differential equations). The Runge–Kutta-Fehlberg-45 (RKF-45) order approach and shooting technique are employed to solve the resulting ODEs. Also examined the significant engineering quantities. The important results of this work illustrate that the velocity profile will improve by elevating the values of the solvent fraction constraint in the case of Sakiadis flow, and the opposite action in the Blasius flow. In the case of Sakiadis and Blasius flows, the temperature profile elevates as the radiation constraint value increases for both linear and non-linear thermal radiation. For both cases (Blasius and Sakiadis flows), the Nusselt number will rise as the radiation constraint and magnetic constraint values increase.

Endothermic/exothermic chemical reaction applications are examined in several technical and scientific domains, most notably heat and mass transmission. The main focus of the bioconvection study is on enhancing mass species and energy, which has significance for the civil, electrical, and mechanical engineering sectors. Due to above mentioned applications, the current study investigates how bioconvection and exothermic/endothermic chemical reactions affect the flow of nanofluids via a horizontal deforming circular cone. Additionally, the current study investigates the steady incompressible Casson nanofluid flow in three dimensions around a horizontal deforming circular cone. The nonlinear partial differential equations (PDEs) are modified into ordinary differential equations (ODEs). The modified ODEs are resolved by employing the shooting technique and Runge–Kutta–Fehlberg fourth–fifth-order (RKF-45) method. Several useful and related characteristics for connected profiles are represented graphically. Additionally, the engineering factors are also studied. The main conclusions of this investigation indicate that an upsurge in the activation energy constraint causes the temperature profile to improve in the case of an endothermic chemical reaction and to drop in the case of an exothermic chemical reaction. The bioconvection profile reduces with an enhancement in the bioconvection Lewis and Peclet numbers. An improvement in solid volume fraction and the bioconvection Lewis number causes an enhancement in the density number of motile microorganisms. From nanofluid to base fluid changing the values of the porous parameter D a = (1, 2, 3), heat transmission rate is observed from 24.23%, 121.66%, and 32.53%, respectively, in the case of λ 1 * = + 1 and 297.52%, 1041.30%, and 272.86%, respectively, in the case of λ 1 * = − 1 .
