  Maruping, L.M. ; Bala, H. ; Venkatesh, V. ; Brown, S.A.: Going beyond intention : integrating behavioral expectation into the unified theory of acceptance and use of technology.
  In: Journal of the Association for Information Science and Technology. 68(2017) no.3, S.623-637.
  
  Abstract: Research on information technology (IT) adoption and use, one of the most mature streams of research in the information science and information systems literature, is primarily based on the intentionality framework. Behavioral intention (BI) to use an IT is considered the sole proximal determinant of IT adoption and use. Recently, researchers have discussed the limitations of BI and argued that behavioral expectation (BE) would be a better predictor of IT use. However, without a theoretical and empirical understanding of the determinants of BE, we remain limited in our comprehension of what factors promote greater IT use in organizations. Using the unified theory of acceptance and use of technology as the theoretical framework, we develop a model that posits 2 determinants (i.e., social influence and facilitating conditions) of BE and 4 moderators (i.e., gender, age, experience, and voluntariness of use) of the relationship between BE and its determinants. We argue that the cognitions underlying the formation of BI and BE differ. We found strong support for the proposed model in a longitudinal field study of 321 users of a new IT. We offer theoretical and practical IT implications of our findings.

  Brown, S.A. ; Venkatesh, V. ; Hoehle, H.: Technology adoption decisions in the household : a seven-model comparison.
  In: Journal of the Association for Information Science and Technology. 66(2015) no.9, S.1933-1949.
  
  Abstract: We identified 7 theoretical models that have been used to explain technology adoption and use. We then examined the boundary conditions of these models of technology adoption when applied to the household context using longitudinal empirical data from households regarding their purchase and use decisions related to household technologies. We conducted 2 studies and collected 1,247 responses from U.S. households for the first study and 2,064 responses from U.S. households for the second study. Those households that had adopted household technologies were surveyed regarding their use behavior. Potential adopters (i.e., those who had currently not adopted) were surveyed regarding their purchase intentions. This allowed us to identify the most influential factors affecting a household's decision to adopt and use technologies. The results show that the model of adoption of technology in the household provided the richest explanation and explained best why households purchase and use technologies.

  Brown, S.A. ; Dennis, A.R. ; Burley, D. ; Arling, P.: Knowledge sharing and knowledge management system avoidance : the role of knowledge type and the social network in bypassing an organizational knowledge management system.
  In: Journal of the American Society for Information Science and Technology. 64(2013) no.10, S.2013-2023.
  
  Abstract: Knowledge sharing is a difficult task for most organizations, and there are many reasons for this. In this article, we propose that the nature of the knowledge shared and an individual's social network influence employees to find more value in person-to-person knowledge sharing, which could lead them to bypass the codified knowledge provided by a knowledge management system (KMS). We surveyed employees of a workman's compensation board in Canada and used social network analysis and hierarchical linear modeling to analyze the data. The results show that knowledge complexity and knowledge teachability increased the likelihood of finding value in person-to-person knowledge transfer, but knowledge observability did not. Contrary to expectations, whether the knowledge was available in the KMS had no impact on the value of person-to-person knowledge transfer. In terms of the social network, individuals with larger networks tended to perceive more value in the person-to-person transfer of knowledge than those with smaller networks.

  Hu, P.J.-H. ; Brown, S.A. ; Thong, J.Y.L. ; Chan, F.K.Y. ; Tam, K.Y.: Determinants of service quality and continuance intention of online services : the case of eTax.
  In: Journal of the American Society for Information Science and Technology. 60(2009) no.2, S.292-306.
  
  Abstract: This article examines the determinants of service quality and continuance intention of online services. We proposed and empirically tested a model with both service and technology characteristics as the main drivers of service quality and subsequent continuance intention of eTax, an electronic government (eGovernment) service that enables citizens to file their taxes online. Our data were collected via a two-stage longitudinal online survey of 518 participants before and after they made use of the eTax service in Hong Kong. The results showed that both service characteristics (i.e., security and convenience) and one of the technology characteristics (i.e., perceived usefulness, but not perceived ease of use) were the key determinants of service quality. Another interesting and important finding that runs counter to the vast body of empirical evidence on predicting intention is that perceived usefulness was not the strongest predictor of continuance intention but rather service quality was. To provide a richer picture of these relationships, we also conducted a post-hoc analysis of the effects of service and technology characteristics on the individual dimensions of service quality and their subsequent impact on continuance intention and found assurance and reliability to be the only significant predictors of continuance intention. We present implications for research and practice related to online services.

  Dang, Y. ; Zhang, Y. ; Chen, H. ; Hu, P.J.-H. ; Brown, S.A. ; Larson, C.: Arizona Literature Mapper : an integrated approach to monitor and analyze global bioterrorism research literature.
  In: Journal of the American Society for Information Science and Technology. 60(2009) no.7, S.1466-1485.
  
  Abstract: Biomedical research is critical to biodefense, which is drawing increasing attention from governments globally as well as from various research communities. The U.S. government has been closely monitoring and regulating biomedical research activities, particularly those studying or involving bioterrorism agents or diseases. Effective surveillance requires comprehensive understanding of extant biomedical research and timely detection of new developments or emerging trends. The rapid knowledge expansion, technical breakthroughs, and spiraling collaboration networks demand greater support for literature search and sharing, which cannot be effectively supported by conventional literature search mechanisms or systems. In this study, we propose an integrated approach that integrates advanced techniques for content analysis, network analysis, and information visualization. We design and implement Arizona Literature Mapper, a Web-based portal that allows users to gain timely, comprehensive understanding of bioterrorism research, including leading scientists, research groups, institutions as well as insights about current mainstream interests or emerging trends. We conduct two user studies to evaluate Arizona Literature Mapper and include a well-known system for benchmarking purposes. According to our results, Arizona Literature Mapper is significantly more effective for supporting users' search of bioterrorism publications than PubMed. Users consider Arizona Literature Mapper more useful and easier to use than PubMed. Users are also more satisfied with Arizona Literature Mapper and show stronger intentions to use it in the future. Assessments of Arizona Literature Mapper's analysis functions are also positive, as our subjects consider them useful, easy to use, and satisfactory. Our results have important implications that are also discussed in the article.

  Hammond, C.C. ; Brown, S.W.: Citation searching : search smarter & find more.
  In: Computers in libraries. 28(2008) no.5, S.10-.
  
  Abstract: At the University of Connecticut, we have been enticing graduate students to join graduate student trainers to learn how to answer the following questions and improve the breadth of their research: Do you need to find articles published outside your primary discipline? What are some seminal articles in your field? Have you ever wanted to know who cited an article you wrote? We are participating in Elsevier's Student Ambassador Program (SAmP) in which graduate students train their peers on "citation searching" research using Scopus and Web of Science, two tremendous citation databases. We are in the fourth semester of these training programs, and they are wildly successful: We have offered more than 30 classes and taught more than 350 students from March 2007 through March 2008. Chelsea is a Ph.D. candidate in the department of communication science at the University of Connecticut (UConn) and was trained as a librarian; she was one of the first peer trainers in the citation searching program. Stephanie is an electronic resource librarian at the University of Connecticut and is the librarian coordinating the program. Together, we would like to explain what we teach in the classes in the hopes of helping even more researchers perform better searches.
