User resistance to information systems implementation has been identified as a salient reason for the failure of new systems and hence needs to be understood and managed. While previous research has ...explored the reasons for user resistance, there are gaps in our understanding of how users evaluate change related to a new information system and decide to resist it. In particular, missing in the explanation of user decision making is the concept of status quo bias, that is, that user resistance can be due to the bias or preference to stay with the current situation. Motivated thus, this study develops a model to explain user resistance prior to a new IS implementation by integrating the technology acceptance and resistance literatures with the status quo bias perspective. The results of testing the model in the context of a new enterprise system implementation indicate the central role of switching costs in increasing user resistance. Further, switching costs also mediate the relationship between other antecedents (colleague opinion and self-efficacy for change) and user resistance. Additionally, perceived value and organizational support for change are found to reduce user resistance. This research advances the theoretical understanding of user acceptance and resistance prior to a new IS implementation and offers organizations suggestions for managing such resistance.
This study examines the adoption of Mobile Internet (M-Internet) as a new Information and Communication Technology (ICT) from the value perspective. M-Internet is a fast growing enabling technology ...for Mobile Commerce. However, despite its phenomenal growth and although M-Internet essentially provides the same services as stationary Internet, its adoption rate in many countries is very low compared to that of stationary Internet. The well-known Technology Adoption Model (TAM) has been used for explaining the adoption of traditional technologies. Most adopters and users of traditional technologies (e.g., spreadsheet, word processor) are employees in an organizational setting who use the technology for work purposes, and the cost of mandatory adoption and usage is borne by the organization. In contrast, adopters and users of M-Internet are individuals who play the dual roles of technology user and service consumer. Most of them adopt and use it for personal purposes, and the cost of voluntary adoption and usage is borne by the individuals. Thus, the adopters of new ICT, especially M-Internet, are also consumers rather than simply technology users. By adopting the theory of consumer choice and decision making from economics and marketing research, this study develops the Value-based Adoption Model (VAM) and explains customers' M-Internet adoption from the value maximization perspective. The findings demonstrate that consumers' perception of the value of M-Internet is a principal determinant of adoption intention, and the other beliefs are mediated through perceived value. The theoretical and practical implications of VAM related to M-Internet are discussed.
Some social networking community service providers have earned revenue by selling digital items to their community members. We examined SNC member decisions to purchase digital items based on ...customer value theory. Six factors were extracted from three dimensions of customer value: functional, social, and emotional value. Our findings indicated that the effects of value on member purchase intentions were significant in terms of the emotional and social dimensions. Our results should help SNC providers by improving their sales of digital items.
The sale of digital items, such as avatars and decorative objects, is becoming an important source of revenue for virtual community (VC) websites. However, some websites are unable to leverage this ...source of revenue, and there is a corresponding lack of understanding about what motivates people to purchase digital items in VCs. To explain the phenomenon, we develop a model based on the theory of self-presentation. The model proposes that the desire for online self-presentation is a key driver for such purchases. We also hypothesize that the social influence factors of online self-presentation norms and VC involvement as well as personal control in the form of online presentation self-efficacy are antecedents of the desire for online self-presentation. The model was validated by using survey data collected from Cyworld (
N
=217) and Habbo (
N
=197), two online social network communities that have been pioneers in the sale of digital items. This work contributes to our understanding of the purchase of digital items by extending the theory of self-presentation and adds to the broader line of research on online identity. It also lends insights into how VC providers can tap this source of revenue.
► We examine relative influence of price and trust on customers purchase decisions. ► We have examined this influence for both potential and repeat customers. ► Perceived trust influences purchase ...decision more strongly than perceived price. ► Perceived price has a stronger influence on purchase decision of repeat customers. ► Perceive trust has a stronger influence on purchase decision of potential customers.
Price and trust are considered to be two important factors that influence customer purchasing decisions in Internet shopping. This paper examines the relative influence they have on online purchasing decisions for both potential and repeat customers. The knowledge of their relative impacts and changes in their relative roles over customer transaction experience is useful in developing customized sales strategies to target different groups of customers. The results of this study revealed that perceived trust exerted a stronger effect than perceived price on purchase intentions for both potential and repeat customers of an online store. The results also revealed that perceived price exerted a stronger influence on purchase decisions of repeat customers as compared to that of potential customers. Perceived trust exerted a stronger influence on purchase decisions of potential customers as compared to that of repeat customers.
Obesity is characterized by an accumulation of macrophages in adipose, some of which form distinct crown-like structures (CLS) around fat cells. While multiple discrete adipose tissue macrophage ...(ATM) subsets are thought to exist, their respective effects on adipose tissue, and the transcriptional mechanisms that underlie the functional differences between ATM subsets, are not well understood. We report that obese fat tissue of mice and humans contain multiple distinct populations of ATMs with unique tissue distributions, transcriptomes, chromatin landscapes, and functions. Mouse Ly6c ATMs reside outside of CLS and are adipogenic, while CD9 ATMs reside within CLS, are lipid-laden, and are proinflammatory. Adoptive transfer of Ly6c ATMs into lean mice activates gene programs typical of normal adipocyte physiology. By contrast, adoptive transfer of CD9 ATMs drives gene expression that is characteristic of obesity. Importantly, human adipose tissue contains similar ATM populations, including lipid-laden CD9 ATMs that increase with body mass. These results provide a higher resolution of the cellular and functional heterogeneity within ATMs and provide a framework within which to develop new immune-directed therapies for the treatment of obesity and related sequela.
The phenomenon of problematic mobile phone use has become increasingly common among adolescents during the lockdowns mandated by the COVID-19 pandemic. However, research is still scarce on the impact ...of such use on delinquent cyberspace conduct (i.e. cyberbullying). This study applies the theoretical framework of general strain theory to examine how problematic mobile phone use affects the perpetration of cyberbullying. The results of this empirical examination of longitudinal survey data obtained from 2,161 adolescents in South Korea reveal that problematic mobile phone use is positively associated with engagement in cyberbullying. It is a type of strain that induces negative emotional states and results in the perpetration of cyberbullying. Furthermore, this study investigates the moderating roles of both traditional bullying experiences (i.e. traditional bullying and victimisation) in the association between problematic mobile phone use and the perpetration of cyberbullying. We found traditional bullying perpetration positively moderates the effects of problematic mobile phone use on cyberbullying. On the other hand, we found the moderating effect of traditional bullying victimisation of adolescents was insignificant.

The increasing popularity of social network services (SNS) presents an opportunity to offer gifting services through SNS. For givers, gifting can be an important means to enhance social ...relationships. On the other hand, for SNS providers, members’ gifting can serve as a major source of revenue. As SNS providers continue to face challenges in generating revenues, understanding how to stimulate gifting through SNS can allow them to profit from members’ relationships. However, there is little understanding of what drives members’ gifting through SNS, with limited prior research on online gifting. Thus motivated, we develop a research model of the antecedents of SNS gifting that builds on social exchange theory and prior gifting literature, and incorporates the unique aspects of such gifting (that we refer to as microgifting, with low-price digital voucher gifts). The theoretical model was validated through a field study, in which both subjective and objective data were collected from an SNS that has been successful in offering such gifting services. Our findings highlight the effects of perceived worth, SNS gifting experience, and the number of SNS friends on the frequency of SNS gifting. The results also show that expected benefits (i.e., reciprocity, pleasure, relationship support, convenience, and immediacy of gift sending) and costs (i.e., impersonality) indirectly impact SNS gifting frequency through the assessment of perceived worth. The study contributes to research by adding to our understanding of this new approach of gifting through SNS, i.e., microgifting. It also lends insights on how SNS providers can offer such services to tap this source of revenue.
