Relating the role of green self-concepts and identity on green purchasing behaviour: An empirical analysis

Abstract: At present, consumers in emerging economies are becoming more conscious about environmental well-being Therefore, organizations compete to make their products and practices more eco-friendly Several studies have tried to explain the relationship between green consumerism and an individual's buying behaviour using traditional theories However, there is quite a challenge in understanding the influence of green self-concept (GSC) and green self-identity (GSI) in predicting the green purchase intention (GPI) of consumers Therefore, the authors developed six hypotheses to assess the relation between self-concept and the GPI The survey was conducted, and the responses were evaluated through the partial least square (PLS) method The authors analysed the measurement model results (n = 717) and the direct and indirect mediating effect of the latent variable contributing to GPI The measurement model results show that a significant relationship exists in the proposed model, namely, GSCs ? green purchasing intentions, product self-concept (PSC) ? green purchasing intentions and GSI ? green purchasing intentions Further, the GSI acted as a mediator for the measurement model The implications of the study can be used to understand the green consumer behavior in developing new strategies and policies for the organizational practice in emerging economies

Optimization and sensitivity analysis of heat transport of hybrid nanoliquid in an annulus with quadratic Boussinesq approximation and quadratic thermal radiation

Abstract: The quadratic convective flow of hybrid nanoliquid in an annulus subjected to quadratic thermal radiation is studied for the first time. The impact of suction/injection and the uniform movement of the rings are considered. Nonlinear equations are handled numerically by adopting the shooting technique. An optimization procedure is performed by using response surface methodology. The maximum heat transport is observed for chosen values of effective parameters (thermal radiation parameter $$ (5 \le Rt \le 15) $$ , temperature ratio parameter $$ (1.1 \le \theta_{w} \le 5.1) $$ and nanoparticle volume fraction of copper $$ (1\% \le \phi_{\text{Cu}} \le 3\% )) $$ at three different levels (low(− 1), middle(0) and high(+ 1)). In addition, a slope of the data point is evaluated for the friction coefficient and the Nusselt number. The results showed that the impact of quadratic thermal radiation on velocity and temperature distributions is more significant than linear thermal radiation. Further, an increase in quadratic convection and quadratic thermal radiation leads to an improvement in the friction coefficient of the skin on the inner surface of the outer annulus. Furthermore, the sensitivity of the friction coefficient is positive for the appearance of quadratic thermal radiation.

Thermal Marangoni convection in two-phase flow of dusty Casson fluid

Abstract: This paper deals with the thermal Marangoni convection effects in magneto-Casson liquid flow through suspension of dust particles. The transpiration cooling aspect is accounted. The surface tension is assumed to be fluctuating linearly with temperature. The fluid and dust particle’s temperature of the interface is chosen as a quadratic function of interface arc length. The governing problem is modelled by conservation laws of mass, momentum and energy for fluid and dust particle phase. Stretching transformation technique is utilized to form ordinary differential equations from the partial differential equations. Later, the numerical solutions based on Runge-Kutta-Fehlberg method are established. The momentum and heat transport distributions are focused on the outcome of distinct governing parameters. The results of Nusselt number is also presented and discussed. It is established that the heat transfer rate is higher in the case of dusty non-Newtonian fluid than dusty Newtonian fluid. The rate of heat transfer can be enhanced by suspending dust particles in a base liquid.
