Abstract
Purpose
This study aims to present compatible computational fluid dynamics procedure for calculation of incompressible three‐dimensional time‐dependent flow with complicated free surface deformation. A computer software is developed and validated using a variety of academic test cases.
Design/methodology/approach
Two fluids are modeled as a single continuum with a fluid property jump at the interface by solving a scalar transport equation for volume fraction. In conjunction, the conservation equations for mass and momentum are solved using fractional step method. Here, a finite volume discretisation and colocated arrangement are used.
Findings
The developed code results in accurate simulation of interfacial flows, e.g. Rayleigh‐Taylor instability, sloshing and dambreaking problems. All results are in good concordance with experimental data especially when there are two phases with high density ratio.
Research limitations/implications
Turbulence, which has great importance in a wide variety of real world phenomena, is not considered in the present formulation and left for future researches.
Originality/value
Here, an integrated numerical simulation for transient interfacial flows is presented. In this way, the pressure integral term in Navier‐Stokes equation is discretised based on a newly developed interpolation which results in non‐oscillative velocity field especially in free surface.

Abstract
Purpose
The purpose of this paper is to develop a finite volume approach for the simulation of three-dimensional two-phase (polymer melt and air) flow in plastic injection molding which is capable of robustly handling the mesh non-orthogonality and the discontinuities in fluid properties.
Design/methodology/approach
The presented numerical method is based on a cell-centered unstructured finite volume discretization with a volume-of-fluid technique for interface capturing. The over-relaxed approach is adopted to handle the non-orthogonality involved in the discretization of the face normal derivatives to enhance the robustness of the solutions on non-orthogonal meshes. A novel interpolation method for the face pressure is derived to address the numerical stability issues resulting from the density and viscosity discontinuities at the melt–air interface. Various test cases are conducted to evaluate the proposed method.
Findings
The presented method was shown to be satisfactorily accurate by comparing simulations with analytical and experimental results. Besides, the effectiveness of the proposed face pressure interpolation method was verified by numerical examples of a two-phase flow problem with various density and viscosity ratios. The proposed method was also successfully applied to the simulation of a practical filling case.
Originality/value
The proposed finite volume approach is more tolerant of non-orthogonal meshes and the discontinuities in fluid properties for two-phase flow simulation; therefore, it is valuable for engineers in engineering computations.

Abstract
Purpose
The present study aims to examine the impact of social media marketing activities (SMMAs) on the adoption of food waste reduction behavior among Generation Z consumers within the restaurant service industry in Pakistan. The study focuses on the impact of social media advertisements and investigates the mediating influence of waste reduction intentions on actual behavior. This underscores the significance of contextual and emotional variables in comprehending consumer behaviors.
Design/methodology/approach
The study used a cross-sectional research methodology to examine the impact of SMMAs on the behavior of Generation Z consumers in Pakistan’s food service industry with regard to reducing food waste. A study was conducted to investigate the restaurant purchasing behaviors of a sample consisting of 449 individuals belonging to the millennial generation, often known as Generation Z.
Findings
The majority of variables related to SMMA, except for interactivity and personalization, were shown to have a positive impact on individuals’ intents to reduce food waste. The study observed a significant relationship between consumers’ intentions to decrease waste and their actual behavior in waste reduction. Furthermore, this relationship was shown to be influenced by the mediating role of waste reduction intention.
Originality/value
Examining how social media affects Pakistani Generation Z’s efforts to reduce food waste is what makes this study distinctive. According to the research, the majority of social media factors positively influence intentions to reduce waste. The relationship between intentions and actual behavior, which highlights the impact of social media campaigns and emotional aspects in promoting waste reduction, is one of the important conclusions.

Abstract
Purpose
The purpose of this study is to investigate consumers’ buying intentions (BIs) towards sustainable properties with green living concept (GLC). It also aims to examine the dynamic relationships between environmental advertisements (EAd), green brand positioning (GBP), attitude towards environmental responsibility (ER) and consumers’ sustainable properties BI in the Malaysian context.
Design/methodology/approach
Data were collected via online questionnaire survey, which yielded 143 completed usable responses. Structural equation modelling–partial least squares (Smart PLS, version 3) was used to analyse the data.
Findings
The findings of this study revealed that EAd and GBP significantly affect consumers’ attitude towards ER, which in turn affects consumers’ BI of the sustainable properties with GLC.
Practical implications
This study suggests that without inculcating a positive attitude towards the environment among consumers, it becomes a daunting task to drive consumers to purchase sustainable properties in Malaysia. Thus, the marketers should focus on green promotional activities to attract more customers to buy sustainable properties with GLCs. Moreover, it is suggested to target the right market segment to secure more sales.
Social implications
The findings of this study will enable the government and the social marketers to understand the drivers of buying sustainable properties with GLC, which in turn will contribute to the higher environmental welfare.
Originality/value
This study is among the pioneers to examine consumers’ sustainable property purchase intention. It provides significant insights for the social marketers and policymakers to understand how to motivate consumers to purchase sustainable properties with GLCs. Moreover, this study has investigated few comparatively new links such as the direct effect of EAd and GBP on attitude towards environmental responsibility and the mediating effect of attitude towards environmental responsibility between environmental stimuli and consumer’s sustainable properties BI.

Abstract
Purpose
In today’s competitive business landscape, organizations are increasingly recognizing the strategic advantage of implementing sustainable practices to gain a competitive edge. This study aims to investigate the effect of green artificial intelligence (AI) on achieving a green competitive advantage, examining the mediating roles of green organizational learning, green product innovation and green process innovation. Additionally, the research explores the moderating role of perceived green climate in the relationship between green AI and these mediating factors.
Design/methodology/approach
This research examined companies in Isfahan, Iran, that have varying levels of artificial intelligence adoption within their business processes. The target population consisted of 148 senior managers from these companies. This study uses structural equation modeling to examine the proposed model.
Findings
Green AI positively impacted green organizational learning and green process innovation but not green product innovation. In addition, the results showed that green organizational learning, green product innovation and green process innovation had positive effects on green competitive advantage. Finally, the results showed that the perceived green climate did not play a moderating role in the relationship between green AI and these mediating factors.
Practical implications
Organizations should prioritize green AI initiatives, foster a culture of green learning and invest in green innovation to achieve sustainable growth and outpace competitors in the environmentally conscious marketplace.
Originality/value
This study positions itself at the forefront of research on green AI and green competitive advantage. It offers a unique framework by examining the combined effects of green AI, green learning and both product and process innovation on achieving a sustainable competitive advantage.

Abstract
Purpose
The research analyzes the influence of three environmental triggers, i.e. awareness, concern and knowledge on environmental attachment and green motivation that affect tourists' pro-environmental behavior in the Pakistan’s tourism industry. Furthermore, this study has analyzed the moderating role of moral obligation concerning environmental attachment and green motivation on tourists' pro-environmental behavior.
Design/methodology/approach
Data were gathered via a structured questionnaire by 237 local (domestic) tourists of Pakistan. Furthermore, the data were examined by employing SmartPLS.
Findings
Findings demonstrate that all three environmental triggers have a positive and significant relationship with environmental attachment and green motivation. Accordingly, environmental attachment and green motivation promote tourists' pro-environmental behavior. Furthermore, the moderating role of moral obligations has also been incorporated in the study. The finding reveals a strong and positive relationship among environmental attachment and tourists' pro-environmental behaviors during high moral obligations. In contrast, moral obligations do not moderate association between green motivation and tourists' pro-environmental behavior. Therefore, competent authorities should facilitate tourists to adopt environmentally friendly practices; which will ultimately promote pro-environmental behavior.
Originality/value
This study provides useful insights regarding the role of tourism in fostering environmental attachment and green motivation that sequentially influence tourist pro-environmental behavior. Secondly, this research has employed moral obligations as a moderator to identify the changes in tourists’ pro-environmental behavior based on individuals' ethical considerations. Hence, the study provides an in-depth insight into tourists' behavior. Lastly, the present research offers effective strategies for the tourism sector and other competent authorities to increase green activities that can embed the importance of the environment among individuals.

Abstract
Purpose
Green human resource management (HRM) plays a vital role in improving employees’ green behaviour. A research gap exists in the roles psychological green climate and employee green commitment have in the relationship between green HRM and employees’ green behaviour. Building on social exchange and social identity theories, this study aims to propose a model of the effects of green HRM on employees’ green behaviour through the serial mediation of psychological green climate and employee green commitment.
Design/methodology/approach
Data were collected from 297 full-time employees working in various manufacturing organizations in India using cross-sectional research design and self-reported measures. Structural equation modelling was used to examine the model fit of the serial mediation model, and PROCESS macro with a bias-corrected bootstrapping method was used to test the hypotheses.
Findings
The result of the study revealed that green HRM impacts employees’ green behaviour. Further, the findings showed that both psychological green climate and employee green commitment individually mediate the relationship between green HRM and employees’ green behaviour. The key outcome of this research is the partial serial mediation of psychological green climate and employee green commitment in the relationship between green HRM and employees’ green behaviour.
Originality/value
This is one of the primary studies that examined the serial mediating effect of psychological green climate and employee green commitment in the relationship between green HRM and employees’ green behaviour. This study contributes to the existing literature on green HRM and green behaviour by evincing the mediating mechanism of psychological green climate and employee green commitment.

Abstract
Purpose
This study aims to investigate the relationship between banks’ corporate social responsibility (CSR) mechanisms at the governance level and their likelihood of pursuing green product strategies. It also examines how CSR characteristics and green product strategies have evolved across regions and time.
Design/methodology/approach
Using a sample of listed banks from different economic areas over the period 2010–2019, the authors examine how CSR mechanisms at the governance level and green product strategies, which they categorize through principal component analysis, have changed over time and across regions. The authors then conducted panel regression to identify which CSR characteristics affect the likelihood that banks implement green product strategies.
Findings
Results show that CSR mechanisms related to bank transparency and commitment to the community, such as sustainability reporting and United Nations Global Compact adherence, are substantive in affecting the likelihood of banks pursuing green product strategies. In contrast, mechanisms related to internal organization, such as the presence of a CSR Committee and an environmental management team, tend to play more a symbolic role. Findings also support a reconsideration of environmental, social and governance-related compensation schemes, which appear to decrease the likelihood that banks engage in some forms of green financing. The likelihood of banks pursuing green product strategies varies across regions and has increased after the Paris Agreement.
Research limitations/implications
The findings are useful in guiding regulators, supervisory authorities and policymakers in defining policies that can create conditions for banks to develop green products and, hence, encourage the sustainability behaviors of their clients. Empirical evidence reveals that some corporate governance mechanisms and green product strategies correlate positively, institutional factors matter and public policies can play a role in strengthening such a correlation. However, results are limited to specific geographical areas and listed banks.
Originality/value
This study contributes to the institutional literature by showing that some corporate governance mechanisms are substantive in increasing the likelihood of banks pursuing green product strategies, while others are more symbolic. It also extends the literature by analyzing how banks belonging to different geographical areas have responded, over time, to sustainability objectives.

Abstract
Purpose
Based on the knowledge-based view (KBV) and theory of planned behavior (TPB), the study aims to investigate the impact of sustainable leadership (SL) on knowledge management processes (KMPs) and the direct influence of KMPs on sustainable competitive advantage (SCA). Additionally, it aims to explore the mediating role of knowledge worker social responsibility (KWSR) in the relationship between KMPs and SCA. Furthermore, this study aims to evaluate the moderating effect of knowledge sabotage behavior (KSB) on the relationship between KMPs and KWSR.
Design/methodology/approach
The sample frame consisted of 354 academic and administrative workers from Pakistan’s higher education institutions. The hypothesized relationships were tested using the PLS-SEM approach.
Findings
The study found a significant positive effect of SL on KMPs as well as KMPs on SCA. Partial mediation of knowledge worker social responsibility between knowledge management processes and sustainable competitive advantage was confirmed. Furthermore, our findings indicate the negative moderating effect of knowledge sabotage behavior on the relationship between KMPs and KWSR.
Practical implications
The outcomes of this research strengthen the universities’ experience of Leadership and recommend how academics and administrators of higher education institutes can value knowledge management, which improves competitive advantage.
Originality/value
The originality of the study lies in elucidating the direct relationship of SL & KMPs with the moderating role of KSB in the link between KMPs and KWSR and the mediating effect of KWSR on the relationship between KMPs and SCA in the setting of higher education institutions (HEIs) in Pakistan. Furthermore, this study provides in-depth insights into the existing body of knowledge on the KBV and TPB about SL, KMPs, and SCA.

Abstract
Purpose
This study aims to examine the associations between the three goals (hedonic, gain and normative) and university students’ proenvironmental behavior. After that, the authors investigate how environmental knowledge acts as a mediator between three goals (hedonic, gain and normative) and proenvironmental behavior.
Design/methodology/approach
The study used the quantitative approach adopting the goal framing theory (GFT) as the theoretical framework, for analyzing behavior of university students toward environment including both undergraduate and postgraduate levels. The data was gathered through the distribution of a structured questionnaire to private universities in Chattogram and structural equation modeling was used to analyze the data.
Findings
Hedonic and gain goals have positive effects on students’ proenvironmental behavior while the normative goal has insignificant association. In addition, all the three goals are significantly linked with students’ environmental knowledge. Besides, environmental knowledge significantly mediates the association between three goals and proenvironmental behavior.
Practical implications
The findings can provide valuable insights for integrating sustainability and environmental education into the formulation and planning of curricular and extra-curricular activities, with an emphasis on students’ intrinsic motivation.
Originality/value
The mediating role of environmental knowledge between three goals and proenvironmental behavior is the unique contribution of this study.
