The purpose of this study was to understand factors affecting market mavens' use of social media for fashion-related information provision. The study examined market mavens' motivations to share fashion-related information. Specifically, this study investigates the impact of their motivations (i.e. pleasure from helping, a sense of obligation) and technology acceptance model variables (i.e. beliefs about and attitude toward using social media) on intention to use social media for sharing fashion-related information.

An online survey yielded 862 responses from US female respondents. A subset (N = 307) representing those high in market mavenism was used for the study. Structural equation modeling was employed for the analysis.

The results confirmed that market mavens were driven by pleasure from helping and a sense of obligation to share fashion-related information. These motivations and attitude toward using social media to disseminate fashion-related information positively influenced market mavens' intention to use it to disseminate fashion-related information. Furthermore, belief variables (i.e. perceived usefulness, ease of use and enjoyment associated with social media) indirectly impacted this intention.

The study adds to the scant research examining market mavens' motivations for sharing fashion-related information with others and their intention to use social media. It provides valuable insights for fashion retailers looking to enhance the impact of social media marketing through the deployment of market mavens – very knowledgeable, motivated and trusted consumers.

This study aims to explore the relationships between gender, gender identity and Word of Mouth (WOM). There are three objectives of this study. The first was to observe the impact of gender identity on WOM. The second was to examine the mediation role of self-brand connection (SBC) bridging the relationship between gender identity and WOM. The final one was to test the moderating role of gender.

The conceptual model was tested by analyzing data collected via Mturk from Americans participants who use Airbnb. Confirmatory factor analysis was conducted to evaluate the psychometric property. To test hypotheses, the structural equation model was assessed. Further, Hayes’ PROCESS was adopted to examine the mediation role of SBC. The moderation role of gender was examined by the chi-square difference test.

The research outcomes elucidated that feminine gender identity exerted a noteworthy influence on WOM communication, whereas masculine gender identity appeared to bear no significant impact on WOM. It was determined that SBC operates as a potent mediator bridging the relationship between gender identity and WOM. Gender did not demonstrate a significant moderating effect on any part of the WOM communication pathway in the context of this study.

The conclusions drawn from this research underscore that practitioners in the field of brand management should not overlook the crucial role of consumers' gender identity. It is imperative to cultivate robust, positive relationships with consumers as a strategic measure to engender favorable WOM communication.

This investigation distinguishes itself as one of the relatively scarce studies interrogating the relationship between gender identity, gender and WOM, specifically through the mediating lens of SBC. Consequently, the discoveries made herein have the potential to furnish unprecedented insights into comprehending consumer behavior in the hospitality industry with respect to WOM communication, particularly as it pertains to the dimension of gender identity.

This study aims to investigate the potential of the decorated boron nitride nanocage (BNNc) with transition metals for capturing carbon monoxide (CO) as a toxic gas in the air.

BNNc was modeled in the presence of doping atoms of titanium (Ti), vanadium (V), chromium (Cr), cobalt (Co), copper (Cu) and zinc (Zn) which can increase the gas sensing ability of BNNc. In this research, the calculations have been accomplished by CAM–B3LYP–D3/EPR–3, LANL2DZ level of theory. The trapping of CO molecules by (Ti, V, Cr, Co, Cu, Zn)–BNNc has been successfully incorporated because of binding formation consisting of C → Ti, C → V, C → Cr, C → Co, C → Cu, C → Zn.

Nuclear quadrupole resonance data has indicated that Cu-doped or Co-doped on pristine BNNc has high fluctuations between Bader charge versus electric potential, which can be appropriate options with the highest tendency for electron accepting in the gas adsorption process. Furthermore, nuclear magnetic resonance spectroscopy has explored that the yield of electron accepting for doping atoms on the (Ti, V, Cr, Co, Cu, Zn)–BNNc in CO molecules adsorption can be ordered as follows: Cu > Co >> Cr > Zn ˜ V> Ti that exhibits the strength of the covalent bond between Ti, V, Cr, Co, Cu, Zn and CO. In fact, the adsorption of CO gas molecules can introduce spin polarization on the (Ti, V, Cr, Co, Cu, Zn)–BNNc which specifies that these surfaces may be used as magnetic-scavenging surface as a gas detector. Gibbs free energy based on IR spectroscopy for adsorption of CO molecules adsorption on the (Ti, V, Cr, Co, Cu, Zn)–BNNc have exhibited that for a given number of carbon donor sites in CO, the stabilities of complexes owing to doping atoms of Ti, V, Cr, Co, Cu, Zn can be considered as: CO →Cu–BNNc >> CO → Co–BNNc > CO → Cr–BNNc > CO → V–BNNc > CO → Zn–BNNc > CO → Ti–BNNc.

This study by using materials modeling approaches and decorating of nanomaterials with transition metals is supposed to introduce new efficient nanosensors in applications for selective sensing of carbon monoxide.
