The purpose of this paper is to explore the determinants of pre‐service teachers' perceived usefulness of e‐learning for teaching and learning.

A total of 189 pre‐service teachers completed a survey questionnaire measuring their responses to four constructs which explain perceived usefulness in the context of e‐learning: learning environment (LE), course delivery (CD), tutor attribute (TA), and facilitating conditions (FC). These were administered during the teaching term where participants were attending a technology course. Structural equation modeling (SEM) was employed for modeling and data analysis.

Results revealed that 62.5 percent of the total variance in the pre‐service teachers' perceived usefulness of e‐learning was explained by the four variables. Among them, learning environment did not have a significant influence on perceived usefulness. Overall, the data in this study provided evidence to support the notion that perceived usefulness is a multidimensional construct.

Perceived usefulness is often employed as an independent variable within a model (technology acceptance model) or theory (theory of planned behavior) in many acceptance studies. This study provides an alternative perspective and new insights of perceived usefulness by positioning it as a dependent variable. Methodologically, this study employed structural equation modeling as the technique to assess the effect of each of the four variables on perceived usefulness, something that conventional techniques (e.g. t‐test, ANOVA) cannot do because the latter are not capable of analyzing latent and observed indicators simultaneously.

The conclusions of studies on the factors correlated with the perceived usefulness of online reviews are inconsistent due to differences in research perspectives, research objects, research methods and data types. This study conducted a meta-analysis to verify a proposed model of perceived usefulness to obtain general conclusions.

A meta-analysis was conducted to study the factors correlated with the perceived usefulness of online reviews based on 51 studies.

The results indicate that, with the exception of negative reviews, the order of relevance for the perceived usefulness of online reviews is as follows: the trust tendency of review readers, review replies, review depth, review pictures, reviewer trustworthiness, positive reviews, reviewer expertise, review time and reviewer information disclosure. Perceived usefulness was significantly positively correlated with purchase intention. Review time, positive reviews and negative reviews were also more significantly correlated with perceived usefulness for search products than for experiential products. Review depth, reviewer trustworthiness, reviewer expertise and purchase intention had greater positive correlations with perceived usefulness for experiential products than for search products.

This study proposes an extended information adoption model based on argument quality and source credibility. The model includes personal factors such as the trust tendency of review readers, constructs a theoretical model of the factors correlated with the perceived usefulness of online reviews and considers the moderating effects of product type.

The purpose of this study is to clarify theory and identify factors that could explain the level of fintech continuance intentions with an expectation confirmation model that integrates self-efficacy theory.

With data collected from 753 fintech users, this study applies partial least square structural equation modeling to compare and select the research model with the most predictive power.

The results show that financial self-efficacy, technological self-efficacy and confirmation positively affect perceived usefulness. Among these factors, financial self-efficacy and technological self-efficacy have both direct and indirect effects through confirmation on perceived usefulness. Perceived usefulness and confirmation are positively related to satisfaction. Finally, perceived usefulness and satisfaction positively influence fintech continuance intentions.

To the best of our knowledge, this is one of the earliest studies that investigates the effect of domain-specific self-efficacy on fintech continuance intentions, which enriches the existing research on fintech and deepens our understanding of users' fintech continuance intentions. We distinguish between financial self-efficacy and technological self-efficacy and specify the relationship between self-efficacy and continuance intentions. Moreover, this study highlights the importance of assessing a model's predictive power using the PLSpredict technique and provides a reference for model selection.

The purpose of the study is to investigate the effects of interactivity and vividness on perceived usefulness and perceived enjoyment and their consequent impacts on consumer behavioral responses in a retail furniture VR store context. Considering the lack of VR empirical research, the indirect effect of interactivity and vividness on perceived usefulness and perceived enjoyment through telepresence and the moderating effect of consumer previous experience with VR are also included.

A commercial IKEA VR store was chosen for the study. Head-mounted display (HMD) VR headsets were employed for the VR shopping experience. The study was conducted at a laboratory at a large university in the southeastern United States. A total of 146 college students participated in the study.

Vividness had significant positive effects on perceived usefulness and perceived enjoyment, which in turn influenced attitude towards VR and behavioral intentions. Interactivity did not have positive impacts on perceived usefulness and perceived enjoyment. However, it indirectly affected perceived usefulness and perceived enjoyment through telepresence. The findings also proved the moderating effect of consumer previous VR experience between interactivity and perceived usefulness and between interactivity and perceived enjoyment. The relationship between attitude and behavioral intentions was also positive.

Notwithstanding the benefits of VR in relation to its utilitarian, hedonic, and behavioral values, little is known about consumers' responses towards the usage of VR as a shopping tool. The present study can be considered as a starting point in understanding the usefulness of VR from consumer and managerial perspectives. The findings of VR indicated in the study will help practitioners understand the urgency of adopting VR in a retail setting.

Understanding customer behavior from the perspective of channel integration has become a major stream of research in multi-channel retailing literature. Yet, despite recent advancements in scholarship, how retailers can most effectively sustain customers in online retailing remains unclear. Scholars have suggested online–offline channel integration (OOCI) as an effective multi-channel approach for increasing online loyalty; yet, few studies have explored OOCI's influencing mechanism. This study addresses that gap by investigating how OOCI helps achieve customer loyalty online and further examines the moderating role of retailer credibility in the influencing mechanism of OOCI.

The research model driving this study draws upon the stimulus-organism-response (S-O-R) model and cue consistency theory. The authors collected a sample of 259 customers in China with experience making multi-channel purchases from retailers that have implemented OOCI in online retailing. Structural equation modeling and response surface analyses were employed to conduct data analysis.

The results revealed that the relationship between OOCI and customers' online channel loyalty was mediated by customers' perceptions of the usefulness and risks of online channel usage. The results also found that congruence and incongruence between informational OOCI (IOOCI) and fulfillment OOCI (FOOCI) had different curvilinear associations with perceived online channel usefulness and perceived online channel risk. In addition, retailer credibility weakened the effects of IOOCI on perceived online channel usefulness and FOOCI on perceived online channel risk but strengthened the effect of IOOCI on perceived online channel risk and had no impact on the effect of FOOCI on perceived online channel risk.

Theoretical and practical implications of this study are also discussed.

The purpose of this paper is to answer “Why do Chinese consumers use IOT systems?” and “Do consumers’ cognitive and affect experiences moderate the relationship between psychological perception factors and perceived usefulness?”

In-depth interview with consumers and experts had been conducted and then the perceived psychological factors that influence perceived usefulness had been summarized. Based on a survey test of 337 smart home users, this study applies partial least squares technique analysis to test the research model.

The research results show that perceived psychological factors (perceived ease of use, perceived intelligence, perceived convenience and perceived privacy risk) have significant effect on the intention and behavior of IOT systems usage through perceived usefulness. Cognitive experience moderates the relationship between perceived ease of use and perceived usefulness, perceived privacy risk and perceived usefulness; affect experience moderates the relationship between perceived ease of use and perceived usefulness.

The current study mainly tested the antecedents of consumers’ usage of IOT systems, and the outcome of using the system was not investigated. Future research can examine the outcome (e.g. satisfaction, perceived value) by using the expectation-confirmation theory.

This study provides a useful insight into the key driving factors in consumers’ intention and behavior of using IOT systems. The previous studies over IOT systems have not observed consumers’ perception of IOT systems, but in fact IOT systems are being applied to more and more personal users.

This study aims to investigate the factors influencing consumers' continued social commerce (s-commerce) intention and its underlying mechanism.

The authors define continued s-commerce intention as consumers' intention to continually participate in s-commerce activities, namely, requesting and sharing commercial information. Grounded in the motivation theory, perceived usefulness and perceived enjoyment are identified in this study as the motives behind consumers' continued s-commerce intention. Given the indispensable social facet of s-commerce, the authors include social support as another critical social factor motivating continuance intention. Furthermore, users' perceptions are affected by prior s-commerce outcomes, which concern the effectiveness of the commercial information exchange process. Research suggests that in such a context, the result of communication is jointly determined by source credibility and interactive relationships amongst individuals. Whilst source credibility determines the usefulness of the information transmitted, a social interaction supports this process. Therefore, source credibility and social interactions are crucial to the outcomes of s-commerce, which, in turn, affect consumers' perceived usefulness, perceived enjoyment and social support in s-commerce. Building on these arguments, the authors propose our research model and then test the hypotheses via a survey.

The authors find that consumers' perceived usefulness and informational social support of s-commerce directly affect their continued s-commerce intention. Moreover, perceived enjoyment leads to continued s-commerce intention via the mediation of perceived usefulness, whilst emotional social support influences continued s-commerce intention through the mediator of informational social support. In addition, source credibility is a significant antecedent of consumers' usefulness, enjoyment and social support perceptions, whilst a social interaction significantly impacts perceived enjoyment and social support.

Various consumer behaviours in s-commerce have been studied; however, the continuance intention to participate in the s-commerce activity remains unknown. This empirical study fills this research gap. Moreover, the authors initially reveal s-commerce participants' utilitarian orientation in the post-adoption stage: perceived usefulness and informational social support affect continuance intention more directly than perceived enjoyment and emotional social support. Further, prior studies on information systems continuance have mainly focused on technical features. By identifying the influence from social factors, i.e. social support, this work extends the literature on information systems continuance.

This study aims to examine the drivers and outcomes of the usage intention of branded mobile applications (apps), revealing findings of theoretical and practical relevance. First, it uncovers the specific technological features that underpin the perceived usefulness and ease of use of branded apps driving (directly and indirectly) usage intention. Second, it outlines two key outcomes that are relevant to the strategic management of branded apps: willingness to recommend the app and willingness to pay to continue using the app.

This study uses data randomly derived from a panel of one million UK consumers, analyzed via structural equations modeling. The unit of analysis was individual apps prominently displaying a brand identity. The study tested indirect relationships between the key drivers considered and usage intention via perceived usefulness and ease of use.

Consumers who view branded apps as protecting their privacy, customizable and compatible with what they do, will have stronger perceptions of usefulness and ease of use and greater intention to use the app. These effects also occur indirectly. Furthermore, usage intention drives the willingness to recommend the app and to pay to continue using it.

To influence usage intention, managers can improve the perception of usefulness of branded apps by protecting consumer privacy and improving the app’s design and its compatibility with people’s needs and lifestyle. Managers can also enhance the perception of ease of use of the branded app by heightening its security and ubiquity. Combined, these factors can enhance (directly and indirectly) the intention to use the app, which will lead to the willingness to recommend the app and pay for it.

This study extends previous research by examining factors driving the intention to use branded apps and the resulting outcomes. It also offers a model that yields predictions for individual branded apps (not the brand powering the app), thus providing practical recommendations on how to manage, in general, apps with a brand identity.

Collaborative consumption (CC), a unique business model, provides several monetary and non-monetary benefits to customers. Several adapted theory of planned behaviour (TPB)-based models were developed and tested to understand this consumption behaviour with the findings inconsistent and fragmented. Thus, this study aims to develop a general and consistent TPB model using a meta-analytic path analysis to better understand customers’ CC adoption behaviour.

Using 37 studies, a meta-analysis was performed adopting several analytical methods; bivariate analysis, moderation analysis and path analysis.

The universal TPB model shows that factors, that is, trust, attitude, perceived environmental responsibility and communication facilities, drive both perceived usefulness and CC. However, subjective norms, such as perceived behavioural control and emotional value, drive only perceived usefulness. Moderation analysis shows that the relationships between variables used in the proposed TPB model tends to vary depending on five moderators, that is, countries’ economic development level, type of CC, sample size, sample type and survey administration method.

The consideration of only quantitative papers and papers written in English language in this meta-analysis may bias the study’s findings.

Based on the findings regarding important factors that consumers consider when adopting CC, this study provides insightful recommendations to companies facilitating CC.

By developing the universal TPB model, this study theoretically contributes to the TPB model, and by conducting the moderation test, the study contextually contributes to the TPB literature in the CC context.

The study examined the applicability of TAM2 theoretical constructs of social influence and cognitive instrumental factors vis-à-vis the facilitation of perceived usefulness of electronic resources among library personnel in private universities in South-west Nigeria.

Descriptive research design of correlational type alongside the single-stage random sampling technique were used to select 212 respondents from a population size of 259 library personnel across the 21 private universities in South-west Nigeria. The instrument used to elicit data was the questionnaire. Of the 212 copies of the questionnaire administered, 181 (85.4 per cent) were found valid for analysis.

Social influence and cognitive instrumental factors significantly had relationship with and facilitated perceived usefulness of electronic resources. Similarly, the study revealed that cognitive instrumental factors are stronger facilitators of perceived usefulness of electronic resources than social influence factors among library personnel in private universities in South-west, Nigeria.

Implementation of electronic resources without ascertaining library personnel usefulness perception leads to resource underutilisation and wastage. Management of private university libraries should, therefore, take into cognisance the usefulness perception of library personnel before the implementation of electronic resources for optimum utilisation.

There is no known research endeavour within the Nigerian context that examined perceived usefulness of electronic resources among library personnel in the private university domain, using the additional theoretical constructs of TAM2 as our research model suggests. This study is, therefore, a pioneering effort towards ascertaining library personnel’s perceived usefulness of electronic resources prior acceptance and use in private university libraries.
