The emergence of various forms of digital money and innovative digital financial services allows stores of value to be created, held, moved, measured, and exchanged in novel ways. Yet the success of these new forms of transactional media is largely dependent on the ways that they are understood as useful and credible as viable forms of exchange, and on how they support the ways that their users interact around them. This article therefore examines interactional work around the use of money in making financial transactions: we call this moneywork. We report on an empirical study of the patterns of behavior of users of a mixed media (digital and analog) currency that supports mobile device payments-the Bristol Pound-exploring the impacts of its users' understanding of the systems that underlie these transactions, the technical constraints on their potential for action, their practices of use, and the social interactions that these activities lie within. We draw design implications to support these payment practices.

As cloud computing continues to gain more momentum in the IT industry, more issues and challenges are being reported by academics and practitioners. In this paper, we aim to attain an understanding of the types of issues and challenges that have been emerging over the past five years and identify gaps between the focus of the literature and what practitioners deem important. A systematic literature review as well as interviews with experts have been conducted to answer our research questions. Our findings suggest that researchers have been mainly focusing on issues related to security and privacy, infrastructure, and data management. Interoperability across different service providers has also been an active area of research. Despite the significant overlap between the topics being discussed in the literature and the issues raised by the practitioners, our findings show that some issues and challenges that practitioners consider important are understudied such as software related issues, and challenges pertaining to learning fast-evolving technologies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
