This study aims to examine the determinant factors of perceived online community usefulness from a motivational point of view. The researchers have combined the use of the expectancy value model and the information system continuous-use model to predict continuous knowledge-sharing behaviour between online community members. This research provides an additional view of current literature focusing on technology-related factors.

This research has adopted a quantitative research method, with data being collected through a Web survey technique. The members of online business communities were invited to participate in the survey. A total of 220 respondents participated in the online survey. These data were then analysed using structural equation modelling.

The research findings revealed that motivation-related factors have a moderate ability to predict members’ perception of online community usefulness. The research findings have shown that attainment and utility values are two significant motivational factors, which can positively influence perceived online community usefulness. By promoting these values, continuous knowledge-sharing intentions can be encouraged through perceived online community usefulness.

Having members from communities other than online business communities might deliver different results, given that they have different needs and values. Also, this study only received responses from active contributors within selected online business communities. The responses from non-active contributors were not included in this study.

This study provides practical suggestions on how the administrators and designers of an online community can promote positive values within their community platform, using motivation-related mechanisms.

The existing literature that examines the determinants of perceived online community usefulness have mainly directed attention towards technology-related factors. This study fills the gap by examining the determinant factors of this construct from a motivation perspective.

A strong and repeating theme in sales force automation (SFA) tool research is perceived usefulness. When salespeople perceived high levels of SFA tool usefulness, they report higher intent and actual use. The authors aim to apply agency theory to the concept of perceived usefulness (from the technology acceptance model) to explain why salespeople adopt some forms of SFA and reject still others. A set of hypotheses are proposed and tested revealing that salespeople will decide to use a SFA tool because they perceive it to be useful to themselves (i.e. PU_sp) and to their management (PU_sm).

Based on responses from 105 salespeople, the SFA tools they used were categorized as either outcome‐based (i.e. helping salespeople achieve their selling outcome goals) or activity‐based tools (i.e. helping management monitor selling activities/behaviors). Regression analyses were used to test six hypotheses relating salespeople's usage of each category of tools (the dependent variable) to the salesperson perceived usefulness constructs (both PU_sp and PU_sm – the independent variables).

The findings confirm that SFA tool use (either outcome‐based or activity‐based) is a function of both forms of perceived usefulness (i.e. PU_sp and PU_sm). Furthermore, when PU_sp is high, the salesperson is more likely to use outcome‐based (versus activity‐based) SFA tools over a longer period of time.

The paper validates agency theory as a useful paradigm for understanding salesperson SFA tool adoption. Salespeople will use SFA tools that they view as useful to their productivity and that the sales manager's influence over the salesperson's use of SFA tools may not be as important. To encourage use, firms need to emphasize how a SFA tool can meet salesperson needs.

The paper is the first to hypothesize and test the relationship between perceptions of SFA tool usefulness and actual usage by considering salesperson perception of usefulness to themselves (PU_sp) and perception of usefulness to their sales manager (PU_sm).

The study aims to explore the effects of photograph quality on visual appeal, perceived usefulness and viewers' travel intentions from rational and irrational perspectives while simultaneously providing some references for the management and marketing of tourism destinations.

The study comprises four experiments combined with structural equation modeling to explore the influence mechanism of photograph quality on travel intentions.

(1) Higher-quality photographs offer greater visual appeal and perceived usefulness to viewers, and these relationships are moderated by the photograph source. Specifically, high-quality photographs generated by other tourists have more visual appeal and perceived usefulness to viewers. However, there are no significant differences in the impact of low-quality photographs generated by other tourists and destination marketing organizations (DMOs) on visual appeal and perceived usefulness. (2) Visual appeal and perceived usefulness significantly affect viewers' travel intentions, and visual appeal positively affects perceived usefulness. (3) Travel experience positively moderates the effects of visual appeal and perceived usefulness on viewers' travel intentions.

The study explores the effects of the visual appeal (irrational factor) and perceived usefulness (rational factor) associated with photograph quality on viewers' travel intentions. Photograph source and travel experiences have moderating effects on this influence mechanism.

Despite the digital penetration in the larger consumer market, the adoption of e-pharmacy services is reported to be very low in emerging economies like India. In this context, the purpose of the current study is to examine the influence of consumers’ risk perception on their intention to purchase medicines/pharmaceuticals through online pharmacies. Furthermore, the study seeks to understand to what extent the perceived usefulness of online pharmacy mediates the relationship between different dimensions of perceived risk and purchase intention.

The study was conducted among a sample of 800 consumers in India who are familiar with online e-commerce. To ensure the homogeneity of the sample and hence the generalizations of results, inclusion criteria were set as not to include respondents who have made a prior purchase through e-pharmacy services. Self-reporting questionnaires were administered among the respondents, who were selected through a purposive and convenience sampling method. Measurement modeling and path analysis were done using IBM SPSS 23.0 and AMOS 24.0 to test the hypotheses and draw inferences.

Results revealed that consumers’ risk perceptions, such as financial, product, source and privacy risks, had a significant direct and indirect effect on their intention to purchase medicines through online pharmacies. India is the major universal provider of generic medicines. The insights gained from this study can help policymakers, corporates, consumers, distributors, retailers and marketing managers to frame effective strategies for improved usage of online platforms for procuring medications.

This study is pioneering in conceptualizing and testing a theoretical model linking consumers’ risk perceptions, perceived usefulness and intention to purchase through online pharmacies, particularly in the context of an emerging economy like India. Implications regarding facilitating and nurturing a conducive platform for online purchasing medicines and its outcomes are elaborated, thus striving to fill a gap in the existing literature. By examining the proposed framework through the lens of the technology acceptance model and theory of risk perception, this study seeks to add to the emergent literature on online pharmacies, especially in emerging economies with huge market potential.

The success of an Electronic Health Record (EHR) system is determined by the numerous facilitators and obstacles that influence physicians' intentions toward using these technologies. This study examines physicians' intentions to use EHR by applying the extended technology readiness and acceptance model (TRAM) factors, the result demonstrability, colleagues' opinions, perception of external control, and organizational support.

Convenience sampling was used to collect data from physicians in Egypt (n = 520). To evaluate the model's hypotheses, this study used the partial least squares structural equation modeling (PLS-SEM) method with WarpPLS.7.

The results revealed that positive TR factors (innovativeness and optimism) positively affect perceived usefulness and ease of use, while negative TR factors (discomfort and insecurity) negatively impact perceived usefulness and ease of use. Furthermore, the result demonstrability and colleagues' opinions positively influence perceived usefulness, while the perception of external control and organizational support positively influence perceived ease of use. In addition, significant relationships between perceived ease of use and usefulness and adoption intention were identified.

This is the first study to apply the TRAM to understand physicians' adoption intentions to use EHR systems. Moreover, this study determined the different roles of positive and negative TR affecting physicians' cognition regarding using EHR systems.

The purpose of this research was to investigate at the influence of technology acceptance model (TAM) characteristics including perceived ease of use, perceived compatibility, and perceived security on the perceived utility and actual use of mobile banking among Yemeni academics. It also investigated the function of perceived utility as a moderator in the link between TAM variables and mobile banking adoption. The sample size was 251 respondents who worked at universities in Yemen and were chosen using stratified random selection. According to the findings, perceived compatibility and perceived security had a substantial positive influence on perceived usefulness and real mobile banking use; however perceived simplicity of use had no effect on mobile banking usage. According to the results, perceived usefulness slightly mediated the association between perceived ease of use and security and mobile banking use, whereas it completely mediated the relationship between perceived compatibility and mobile banking usage. Overall, the research proved the significance of TAM elements in academics’ use of mobile banking in Yemen, offering a credible empirical framework for studying mobile banking usage in this setting.

Since the outbreak of the COVID-19 pandemic, the demand for online services has risen, with e-payment emerging as a prominent option for customers seeking faster and more convenient transactions to complete their online purchases. Nevertheless, e-payment adoption in Egypt remains a challenge that requires further investigation. Thus, this study aims to investigate the factors influencing online customers’ attitudes and intentions towards adopting e-payment for online transactions, social influence, perceived ease of use, perceived usefulness, perceived trust, structural assurance and perceived privacy/security risk.

The data were gathered from 302 customers in Egypt and structurally analysed based on partial least squares structural equation modelling (PLS-SEM).

The findings revealed that social influence, perceived usefulness and perceived trust are significant antecedents of attitude. Furthermore, perceived usefulness, perceived trust, perceived privacy/security risk and attitude directly influence behavioural intention. Structural assurance and perceived trust directly influence perceived privacy/security risk. Moreover, perceived usefulness, perceived trust and attitude were found to have several mediating roles.

This study adds new empirical evidence from a developing country regarding the adoption of e-payment among online customers. In addition, its findings can help the government, practitioners and policymakers understand how to promote customers’ positive attitudes and encourage their intentions towards using e-payment.

The findings of this study can contribute to the digital transformation strategy in Egypt by providing insights into enhancing online shoppers’ attitudes and intentions towards e-payment adoption. This, in turn, can boost Egyptian e-commerce and the country's digital economy as a whole.

Emojis are quickly becoming a popular new language in social media and marketing. The capability to express emotions and make message understanding easier is one of the primary reasons for using emojis. The aim of this research was to determine the influence of perceived usefulness, perceived ease of use, trust, and involvement on customer engagement due to emojis used in digital marketing communications among Generation Z (Gen Z) in South Africa.

Following the descriptive research approach, quantitative research was used in this study. A questionnaire (self-administered) was utilized to test the effectiveness of using emojis among 1,000 young consumers. Structural equation modeling was used to test the hypotheses.

The findings of the study yielded positive relationships between the variables, namely between trust and involvement; involvement and the perceived ease of use; involvement and perceived usefulness; perceived ease of use and perceived usefulness; trust and customer engagement; perceived usefulness and customer engagement; involvement and customer engagement; customer engagement and intention to purchase; trust and intention to purchase; and perceived usefulness and intention to purchase.

This study can help organizations in emerging markets use emojis in their digital marketing communications to engage customers and stimulate intention to purchase among young people, especially the Gen Z cohort, who seek organizations and brands that understand and connect with them.

By investigating the effects of emojis in digital marketing communications, this study contributes to the customer-centric process and the literature on emoji usage while also involving a credible digital language when communicating with members of Gen Z. By extending TAM, the findings of this study contribute to the TAM literature by demonstrating that emoji usage in digital marketing communications positively influences various attitudinal associations among Gen Z consumers.

This study aims to explore how perceived usefulness and perceived ease of use affect users' sensory experience and behavioral experience in the metaverse context, and explore the significance of building a metaverse platform for companies, and provide management enlightenment for corporate development.

Data were collected from 329 online participants and analyzed using structural equation modeling and hierarchical regression.

Perceived usefulness and ease of use have a significant influence on customer sensory experience and behavioral experience in the metaverse. Sensory experience mediates the influence of perceived usefulness and availability on behavioral experience. Social presence positively moderates the influence of both usefulness and ease of use on sensory and behavioral experience. In other words, perceived usefulness and perceived ease of use in the metaverse situation affect sensory experience through social presence, and then affect behavioral experience.

This research clarifies the effect of usefulness and ease of use on customer sensory and behavioral experience. It confirms the positive moderating role of social presence and the mediating role of sensory experience in the influence pathway between perceived usefulness, ease of use, and behavioral experience. From the perspective of management, this study provides theoretical support for the positive impact of corporate metaverse platform building on customer brand experience in the future, and provides impetus for companies to pay attention to improving the usefulness and ease of use of their metaverse platform.

This study aims to assess the relative importance of the argument strength, argument sidedness, writing quality, number of arguments, rated review usefulness, summary review rating and number of reviews in determining the perceived usefulness and credibility of an online review. Additionally, the authors use insights from the elaboration likelihood model (ELM) to explore the effect of consumers' product category involvement on the cues' relative importance.

A conjoint analysis (N = 287) is used to study the relative importance of the seven previously mentioned attributes. A balanced orthogonal design generated eight cards that correspond to individual reviews. Respondents scored all eight cards in a random order for perceived usefulness and credibility.

Overall, argument strength is the most important cue, while summary review rating and the number of reviews are the least important for perceived review usefulness and credibility. The number of arguments is more important for people who are more highly involved with the product, while writing quality and rated review usefulness are relatively more important for the low-involvement group.

This study provides a comprehensive test of how consumers perceive online reviews, as it the first to the authors’ knowledge to simultaneously investigate a large set of cues using conjoint analysis. This method allows for the implicit valuation (utility) of the individual cues, revealing the cues' relative importance, in a setting that comes close to a real-life context. Besides, insights of the ELM are used to understand how the relative importance of cues differs depending on the level of review readers' product category involvement.
