The Internet of Things (IoT) is emerging as a significant development in information technology, with the potential to increase convenience and efficiency in daily life. While the number of IoT ...service users has increased dramatically, little is understood about what motivates the continued use of such services. The primary objective of this study is to develop and refine a conceptual framework from the perspective of network externalities and privacy to provide a theoretical understanding of the motivations that drive continued use of IoT services. The proposed model was empirically evaluated using survey data collected from 508 users concerning their perceptions of IoT services. The results indicate network externalities play a significant role in influencing consumers' perception of usage benefits and thus adoption, whereas privacy concerns have a relatively weak effect on adoption. Implications for IS researchers and practice are discussed.
•Network externalities influence consumers' perception of usage benefits and adoption.•Number of IoT services has no direct influence on perceived benefits.•Privacy concerns have a relatively weak effect on IoT adoption.
Recently, there has been a dramatic proliferation of mobile apps, many of which allow for in-app purchases; however, little research has focused on what motivates a user to make such purchases. Based ...on the Affect–Behavior–Cognition model (ABC model) of attitudes, we developed a model involving perceived value and social influences. The model is then empirically evaluated using survey data collected from 485 users regarding their perception of mobile apps. The findings indicate that stickiness and social identification significantly influence a user's intention to make in-app purchases. Specifically, significant differences were found between users and potential users in terms of antecedents to forming stickiness and making in-app purchases. The results may provide further insights into the development of effective mobile app business models and adoption strategies.
•Hedonic and utilitarian values significantly influence a user's affective response.•Stickiness and social identification significantly influence a user's intention.•Determinants of stickiness between users and potential users are different.
•Confirmation was positively related to perceived value and satisfaction.•Free alternatives to paid apps negatively affects a user’s intention to purchase.•Increasing value-for-money will increase ...intention to purchase apps.•Intention to purchase apps was different between users and potential users.
While many reports predict huge growth potential for the mobile application (app) market, little is known about user intention to purchase paid apps. This study amends the expectation confirmation model and incorporates app rating, free alternatives to paid apps and habit as belief-related constructs to predict user behavior. The proposed model was empirically evaluated using a survey of 507 respondents about their perceptions of app usage. The results indicated that confirmation was positively related to perceived value and satisfaction. Value-for-money, app rating and free alternatives to paid apps were found to have a direct impact on intention to purchase paid apps. Specifically, there was a significant difference between potential users and actual users. The results may provide further insights into app marketing strategies.
Purpose - Blogging has become part of a consumer's decision making process when shopping online; however, the understanding of blog recommendation's effect on consumer purchase decision is still ...vague. The purpose of this study is to examine whether the blog reader's trusting belief in the blogger is significant in relation to the perceived usefulness of the blogger's recommendations; and how the blog reader's perceptions influence his her attitude and purchasing behavior online. The moderating effect of blogger's reputation on readers' purchasing intentions is also tested.Design methodology approach - Based on various theories, a model was proposed in this study. A survey involving 327 blog readers as participants was analyzed in the empirical study to investigate whether the usefulness of bloggers' recommendations and trusting beliefs toward blogger had influence on consumers' attitudes and behavioral intentions toward online shopping.Findings - The results indicated that perceived usefulness of bloggers' recommendations and trust had significant influential effect on blog users' attitude towards and intention to shop online. Moreover, the findings showed that different determinants affected the users of perceived-high-reputation and perceived-low-reputation blogs.Originality value - The findings suggest bloggers' electronic word-of-mouth (eWOM) to be a promising marketing strategy for increasing sales. The marketers should provide free trial products and services to the perceived-high-reputation bloggers who, as valued opinion leaders, will influence and prompt others to shop online through a trusting effect. As for perceived-low-reputation bloggers, the marketing strategists should strive to emphasize the usefulness of products and services being marketed, so these perceived-low-reputation bloggers can focus more on describing the advantages and benefits of products or services discussed in their blogs.
The artificial intelligence (AI) chatbot is emerging as a significant corporate customer-facing application, potentially increasin customer service efficiency while reducing costs. However, little ...work has sought to assess the quality of service they provide consumers. This study applies the e-service quality by incorporating conversational AI quality to predict users' satisfaction and loyalty to customer service chatbots. The proposed model was empirically evaluated using survey data collected from 219 users responding about their perceptions of customer service chatbots. The findings indicate that AI chatbot service recovery quality and AI chatbot conversational quality significantly influence user satisfaction. On the other hand, core AI chatbot service quality and satisfaction significantly influenced chatbot user loyalty. This study contributes to researchers and practitioners by proposing and evaluating a more comprehensive chatbot e-service quality that combines both fundamental (core service and service recovery qualities) and human-like (conversational quality) aspects of e-service. The results are of value in devising future AI chatbot services and related strategies.
Recently, there has been a dramatic proliferation in the number of blogs; however, little is published about what motivates people to participate in blog activities. Based on the theory of reasoned ...action, we developed a model involving technology acceptance, knowledge sharing and social influences. A survey of 212 blog participants found strong support for the model. The results indicated that ease of use and enjoyment, and knowledge sharing (altruism and reputation) were positively related to attitude toward blogging, and accounted for 78% of the variance. On the other hand, social factors (community identification) and attitude toward blogging significantly influenced a blog participant's intention to continue to use blogs. Together they explain 83% of the variance of intention to blog.
Live stream services have emerged as a highly profitable Internet application in recent years with rapidly growing audiences for this form of instant and interactive Internet media. This study ...applies media richness theory along with uses and gratifications theory to predict user loyalty to live stream services. The proposed model is empirically evaluated using survey data collected from 295 users responding about their perception of such services. Empirical results show that perceived media richness and gratifications such as entertainment and sociability are antecedents of loyalty, while immediate feedback is the most salient facet of perceived media richness. The results provide further useful insights for service providers and streamers to build loyal user bases.
PurposeThis study combines uses and gratifications theory and flow theory to create an integrated model that predicts continuance intention to use and satisfaction with livestreaming ...services.Design/methodology/approachThe proposed model was empirically evaluated using survey data collected from 304 users about their perceptions of livestream services.FindingsThe results indicate that gratifications such as entertainment, informativeness and sociability were all positively related to satisfaction. The authors find that flow mediates the impact of interactivity and telepresence on satisfaction. Notably, sociability gratification and satisfaction had a significant impact on a user's intention to continue to use livestreaming services and accounted for 77% of the variance.Originality/valueThe study adds to the body of knowledge by demonstrating the uses and gratifications theory and flow theory in live stream services. In addition, the findings may provide useful insights for live stream services streamers and marketers.
The Internet of things (IoT) is seen as a potentially effective means of integrating multiple technologies to improve the quality of life. However, little attention has been paid to factors that may ...have a significant effect on a user's intention to use the IoT services. This study applies the value-based adoption model to examine the influences of benefits (i.e. perceived usefulness and perceived enjoyment) and sacrifices (i.e. perceived privacy risk and perceived costs) on the user's perceived value of and intention to use the IoT services. A structural equation modeling approach is applied to a survey of 489 IoT users, with results indicating that perceived usefulness and perceived enjoyment significantly affect behavioral intention through perceived value. Moreover, perceived privacy risk also plays a key factor in determining IoT adoption. The implications of this study are discussed.
Lung ischemia-reperfusion injury remains one of the major complications after cardiac bypass surgery and lung transplantation. Due to its dual blood supply system and the availability of oxygen from ...alveolar ventilation, the pathogenetic mechanisms of ischemia-reperfusion injury in the lungs are more complicated than in other organs, where loss of blood flow automatically leads to hypoxia. In this review, an extensive overview is given of the molecular and cellular mechanisms that are involved in the pathogenesis of lung ischemia-reperfusion injury and the possible therapeutic strategies to reduce or prevent it. In addition, the roles of neutrophils, alveolar macrophages, cytokines, and chemokines, as well as the alterations in the cell-death related pathways, are described in detail.
