Sustainable green economy is the need of time, and eco-friendly products can play a decisive role in this goal. Low consumption of eco-friendly products is a serious concern of researchers and policymakers. To address this issue, we have studied the phenomenon in a developing country and provided insights to researchers and policymakers about the factors that influence the consumers’ behaviour in developing behaviour. We have designed an integrated model based on UTAUT to study the developing countries’ behavioural intentions towards eco-friendly products. 805 useable sample is obtained to analyze by implying SEM-ANN dual-stage hybrid model. Results revealed that environmental knowledge is a significant predictor and a moderator, but consumers are less educated about ecological issues in developing countries. Results also revealed that male and female consumers’ preferences are differently influenced by factors studied to measure adoption intentions of eco-friendly products. Sensitivity analysis results revealed that social influence followed by effort expectance and perceived expectancy of eco-friendly products are more important for developing countries’ customers. The study also provides empirical evidence of methodological advancement using SEM-ANN and suggests a dual-stage hybrid model in studies involving human behaviour.

During the COVID-19 pandemic, online teaching modes were found vital to continue students’ learning process, but sustainable implementation of online teaching models is an area of concern for policymakers. Psychiatrists are also eager to know students’ behavior toward learning and modes of teaching during COVID-19. We have drawn a model based on the big five personality traits to study students’ satisfaction with online teaching modes and their adoption intentions toward online teaching modes. We have collected data from 718 bachelor’s and master’s level students from four different universities. We have applied the SEM-ANN dual-stage approach to test personality traits’ influence and ranked them based on their normalized importance. The results revealed that agreeableness, conscientiousness, neuroticism, and openness positively influence students’ satisfaction with online teaching models, but that extraversion negatively influences their satisfaction. Agreeableness, extraversion, and neuroticism positively impact, but openness negatively influences. Conscientiousness does not affect adoption intention. Furthermore, agreeableness is the most significant, and conscientiousness is the least important factor for students to adopt online teaching modes. The findings of the study have useful perceptiveness for educational policymakers, academics, and psychiatrists.

Apart from the goal of the digital world and other benefits of e-commerce, it becomes the need of time during this COVID-19 pandemic. Successful implementation and sustainable growth of e-commerce in developing countries is a challenge. The goal of the digital world without the implementation and sustainable growth of e-commerce in developing countries is incomplete. Based on UTAUT theory, we have developed an integrated model to study the developing countries’ consumers’ adoption intentions towards e-commerce. We collected a valid useable sample of 796 respondents from a developing country, applied the SEM-ANN two-step hybrid approach to testing the proposed hypothesis, and ranked the antecedents according to their importance. Results revealed that Trust in e-commerce, Perceived risk of using e-commerce, Ease of use in e-commerce, Curiosity about e-commerce, Facilitating Conditions, and Awareness of e-commerce benefits influence the adoption intentions of developing countries’ consumers. Sensitivity analysis results revealed that Ease of use in e-commerce platforms and awareness of e-commerce benefits are the two most crucial factors behind the adoption intentions in developing countries. The study’s findings help authorities adopt sustainable e-commerce, multinational companies effectively market their goods online, and academics better understand how inhabitants of developing nations perceive e-commerce.
