This research examines the underlying mechanism through which corporate social responsibility (CSR) influences customer loyalty in the hospitality sector. A survey conducted in three popular tourist cities in China reveals that CSR positively impacts customer loyalty through institutional-level constructs, including corporate image and sustained competitive advantage, and individual-level constructs, including customer trust and customer satisfaction. Moreover, the core capabilities of organizations moderate the effect of CSR on corporate image and sustained competitive advantage. Corporate image sustained advantage, and customer satisfaction also mediates the relationship between CSR and customer loyalty. The theoretical and practical implications of these findings are discussed.

This paper aims to examine the impact of service quality and corporate social responsibility (CSR) on brand authenticity and determine the moderating effects of CSR on the relationship between service quality and brand authenticity. Survey data was collected from 472 customers of Karachi, Pakistan’s four major medical diagnostic laboratories, through the convenience sampling technique. The quantitative method was used. To collect information from respondents, a self-administered questionnaire is used. We utilized the partial least squares structural equation modeling (PLS-SEM) technique to analyze data. The results show that CSR, service quality, and brand authenticity are related in medical diagnostic and research laboratories. Research findings indicate that service quality and CSR directly and positively impact brand authenticity. In addition, CSR moderates the effect between service quality and brand authenticity. Managers can see corporate social responsibility as an intangible value that goes along with high-quality services and makes medical diagnostic and research laboratory services more authentic.

This study develops an underlying mechanism outlining the impact of digital influencers on consumer impulse-buying behavior in the context of social networking sites (SNSs). Based on signaling theory, this research examines the role of message credibility (informational value and vicarious expressions) and media credibility (perceived interactivity and transparency) in developing trust in digital influencers, resulting in impulse buying. Moreover, this study explores the moderating effect of social commerce (s-commerce) experience on the relationship between urge-to-buy (UTB) and impulse buying. This study collects data from SNS users. Findings reveal that message credibility and media credibility play a significant role in developing trust in digital influencers, thereby enhancing the urge to buy impulsively on SNSs. In addition, results show that s-commerce experience does not moderate the relationship between UTB and impulsive buying. Finally, this study provides critical insights to marketers and policymakers.

In this study zinc oxide filled and unfilled polyvinyl alcohol (PVA)/polyethylene glycol (PEG) 600 blended membranes with different degrees of cross-linking (mol%) were prepared using formaldehyde as a crosslinking agent and characterized by FTIR, SEM, TGA, mechanical analysis and permeation testing for CO2 and N2 gases. The effects of synthesis parameters like cross-linking ratio, wt.% PEG content and wt.% zinc oxide content on the membrane characteristics were also investigated. It was found that at 60 mol% degree of cross-linking and 60 wt.% PEG content, the membranes showed maximum CO2/N2 ideal selectivity of 26 and reasonable CO2 permeability of 52.9 Barrers at 25 C and 1.5 bar. It was also found that at 2 wt.% zinc oxide content, membranes showed highest CO2/N2 ideal selectivity of 112.8 and maximum CO2 permeability of 423 Barrers at 25 C and 1.5 bar.

Cut spikes of Consolida ajacis cv. Violet Blue were used for the study. The ethylene antagonist (STS) was used in combination with cool storage for 72 h at 5℃ to assess the synergistic effect of both chemical and temperature treatment on postharvest performance of cut spikes. The spikes were divided into three sets, one set was pretreated with STS (1 h Pulse) prior to wet storage at 5℃ for 72 h, while the other set was pretreated after 72 h cool wet storage. The third set of spikes was cool stored (at 5℃) for 72 h but kept unpulsed, which represented control. After 72 h storage, the spikes from all the three sets were transferred to flasks containing distilled water (DW) or 0.2 M sucrose + 100 mg・L-1 8-HQS (SUC + HQS). Pretreatment of spikes with STS before or after wet storage resulted in an improved postharvest performance as compared to the controls. Maximum vase life of about 18 days was shown by spikes pretreated with STS prior to storage and transferred to SUC + HQS as compared to controls which registered a vase life of 10 days in DW and 13 days in SUC + HQS (0.2 M sucrose + 100 mg・L-1 8-HQS). Flower diameter, fresh and dry mass was markedly increased in the samples from spikes transferred to SUC + HQS. Correlation between soluble protein content in sepals and vase life was positive. The results show that soluble protein content in sepals is an important factor in determining the vase life of cut spikes of Consolida ajacis cv. Violet Blue. The study recommends that pulsing the spikes with 0.5 mM STS prior to 72 h wet storage at 5℃ and transferring them to holding solution containing SUC + HQS, can be used as a storage/chemical treatment to improve the postharvest performance of this cut flower.

mixed matrix membrane (MMMs) was fabricated in two steps,first by formation of modified substrateand second is deposition of electrospunfibrous layer with varying sepiolite concentration fornanofiltration. MMM3 showed an optimal MgSO4 rejection of 97.6% with 40.8 L/m2 hflux whileMMM5 showed highest MgCl2 rejection of 96.95% withflux of 31 L/m2 h. The fouling data revealed thatmodified surface is effective in improving the antifouling property which caused decrease in theadsorption phenomena of microbes on to the surface. The antibacterial properties of the membranesshowed the inhibition of the growth of Escherichia coli.

Factors developing brand loyalty through social media influencers (SMIs) are immensely important to academics and marketing practitioners since it is a remarkable driver of organizational success. This research investigates the impact of SMIs homophily in developing customer brand engagement (CBE) and its impact on BL. We collected valid data from 412 respondents using laptop brands in Pakistan and used structural equation modeling to analyze the data. The findings indicate that the SMIs homophily is crucial in establishing CBE and BL. The results further show that CBE’s emotional and cognitive dimensions significantly mediate the relationship between SMIs homophily and BL. However, the emotional CBE has a stronger mediating impact on BL. The study provides valuable insights for brandmanagers to hire SMIs who resemble their fans to grab their loyalty toward the brand. This study unfolds new avenues in social media marketing, consumer behavior, and branding literature by understanding the association between SMIs homophily, CBE, and BL.
