In todays global scenario ecological issue is getting worse, the consumers’ are more concerned about the environmental protection, with the change in consumer buying approach in the steering of a immature lifestyle. As a consequence, firms are implementing potential ecological approaches in the green market industry. Green marketing and green product development are constructive techniques, which are applied by firms to raise competitive advantages and gain the satisfaction of consumers in order to accomplish the firm’s mission and vision.

PurposeDemonetization and pandemic-related restrictions in India propelled the usage of mobile payments (M-payments). The culture of online smartphone transactions is expected to rise over the coming years, even after things return to normal. This study aims to unveil the factors that escalate the satisfaction levels of M-payment users and eventually stimulate them to continue using M-payments for their daily activities.Design/methodology/approachThis study evaluated the intention to continue using M-payments for 710 users utilizing structural equation modeling and augmenting the technology acceptance model (TAM) as well as the expectation confirmation model (ECM). Mediation and moderation analysis examined the proposed model's direct and indirect relationships.FindingsThe findings unveil that perceived value co-creation participation, service quality and cognitive processing magnify user satisfaction, significantly escalating M-payment continuance usage intention. Perceived value co-creation participation and user satisfaction with M-payment partially mediate the linkage among the constructs. Furthermore, perceived usefulness strengthens the link, while perceived severity of security threats weakens the linkage between user satisfaction with M-payment and continuance usage intention.Research limitations/implicationsThe study's findings could benefit M-payment service providers, users, policymakers and the telecom industry to strengthen India's digital payment framework.Originality/valueThe perceived value co-creation participation and cognitive processing domain have not garnered much attention in the M-payment literature. The study strives to comprehend these constructs by widening the purview of TAM and ECM models. It also measures the moderating role of perceived severity of security threats and perceived usefulness to unfurl potential linkages between the identified constructs.

Purpose: The objective of the study was to compare the efficacy and safety of two concentration of autologous serum (AS) 20% vs 50% in recalcitrant moderate-to-severe dry eye patients. Methods: A double-blind prospective, interventional, and randomized study was done on 44 patients (80 eyes) clinically diagnosed with moderate-to-severe dry eye disease (DED) that was refractory to conventional treatment, and all patients were treated with AS20% or AS50% for 12 weeks. We documented Ocular Surface Disease Index (OSDI), tear film breakup time (TBUT), OXFORD corneal staining score (OSS), and Schirmer test (ST) at baseline, 2,4,8, and 12 weeks. These parameters were compared in both groups and between the groups by using Student’s t-test. The study included 11 males and 33 females. Results: Out of 80 eyes, 33 eyes had moderate and 47 had severe DED. The age of patients in AS20% was 44.73 ± 14.37 years, and in AS50% was 46.41 ± 14.47 years. The most common etiology associated with DED was secondary Sjogren syndrome. In moderate DED, both the groups showed significant improvement in both subjective and objective parameters. But in severe DED, the AS20% group failed to show any significant improvement objectively, though subjective improvement was present. Conclusion: In refractory severe DED patients, AS50% is better option for treatment and in moderate DED both concentrations of autologous serum are effective.

Background: Definitive treatment and vaccination are basic necessity to bring down the burden of COVID-19 disease. Due to rapid development of vaccine against COVID-19, associated anxiety and mistrust raises hesitancy for vaccination. We aim to study about the mindset of COVID-19 vaccination among health care employees (HCE) and general population at tertiary care hospital in north east India.Methods: This was a cross sectional and observational study; questionnaires were distributed among 200 HCE and 400 general populations visiting at different OPD regarding their mindset for vaccination. Questionnaires consisted of parameter such as history of previous COVID-19 infection or hospitalization, co-morbidities, job status during pandemic and educational qualification and contained specific questions for causes of vaccine hesitancy.Results: In the survey participants from general population were more hesitant for vaccination as compared to HCE (p<0.001). Most common cause for hesitancy among HCE was pregnancy/lactation followed by concern regarding adverse effects. Doubted efficiency and adverse effects were leading concerns (67%) for vaccine hesitancy among general population. Past history of infection or hospitalization due to COVID-19 did not affect the attitude for getting vaccinated (p>0.05). Among general population, 25% had their job affected during pandemic of which 78% were in favour of vaccination.Conclusions: Increased awareness and high risk of getting infected with COVID-19 makes HCE less hesitant for vaccination. It is important to increase awareness among the general population to bring down the concerns regarding adverse effect and potency of vaccine to reduce the hesitancy for vaccination.
