Although smart service systems have received increasing attention in information systems research, their affordances and constraints processes are less studied. In this study, we draw on interpretive case study methodology and technology affordances and constraints theory to investigate a smart service system use for seaport security in Ghana. With insights from the case of Ghana, we introduce an affordance constraints process as a framework to complement the existing affordance actualisation process framework in information systems. Thus, this study contributes to affordance theory with a new constraints process. The study’s findings show that smart service systems for seaport security afford autonomous access control, real-time security monitoring, and autonomous data capturing for analytics and reporting. However, such affordances can be constrained by power and internet outages, limited storage capacity, and device breakdowns. From these findings, we discuss implications for theory, research, and practice as well as limitations and directions for future research. 相似文献

Past studies of international students and academic libraries have often focused on students' own characteristics and experiences. Using an online survey, this study instead investigated librarians' teaching skills for serving this population. The analysis reveals that participants perceived an importance in developing skills specifically for international students. They tried to accommodate students' unique needs and optimize teaching approaches using their own experience working with the students. Although they reported having obtained knowledge of students' backgrounds as well as communication and teaching techniques, they showed strong interest in having further training opportunities to improve their teaching. The survey results thus give insight into recommendations for the provision of training to improve teaching in the context of serving international students. 相似文献

In recent years, there has been an increasing amount of research published on the topic of e-government diffusion. This paper provides a meta-analytic review of the literature on the diffusion of e-government. We analyzed the related literature in the leading journals and from international conferences in the field of information systems and public administration. Our analytical results reveal the main theoretical foundations, research methods, and research topics found in the relevant literature. The meta-analysis identified four main research topics: (1) the factors that influence the diffusion of e-government, (2) the diffusion of e-government systems and applications, (3) the impacts of e-government diffusion on government agencies and employees, and (4) the relationships between information and communication technology (ICT) infrastructures and the diffusion of e-government. Researchers have developed eight related theories to discuss e-government diffusion and adopted four methods to explore it. We suggest directions that researchers should pursue to strengthen the diffusion of e-government and to draw out deeper issues. 相似文献

A comparison of 10th graders' reading of a narrative, literary text on a Sony e-reader and in print showed that preferences for reading devices are related to gender and to general reading habits.One hundred forty-three students participated in the study. In a school setting, students were asked to begin reading a novel on one device and then continue reading the same novel on the other device. A survey was administered before and after the reading session, measuring reading habits in general, device preferences, and experiences with screen and paper reading. Results showed that, overall, most students preferred reading on the e-reader. This preference was particularly strong among boys and reluctant readers, whereas avid readers were more in favor of print. Implications of these findings to library policies and priorities are discussed. 相似文献

In the IR field it is clear that the value of a system depends on the cost and benefit profiles of its users. It would seem obvious that different users would prefer different systems. In the TREC-9 filtering track, systems are evaluated by a utility measure specifying a given cost and benefit. However, in the study of decision systems it is known that, in some cases, one system may be unconditionally better than another. In this paper we employ a decision theoretic approach to find conditions under which an Information Filtering (IF) system is unconditionally superior to another for all users regardless of their cost and benefit profiles.It is well known that if two IF systems have equal precision the system with better recall will be preferred by all users. Similarly, with equal recall, better precision is universally preferred. We confirm these known results and discover an unexpected dominance relation in which a system with lower recall will be universally preferred provided its precision is sufficiently higher. 相似文献

Linked topics in science and technology (LTSTs) can provide new avenues for technological innovation and are a key step in the transition from basic to applied research. This paper proposes a science and technology semantic linkage integration model for discovering LTSTs. Particularly, the integrative model fuses the term co-occurrence networks of basic and applied research, which expands the completeness of topic networks by enhancing the semantic characteristics of these networks. It is found that link prediction can further reinforce the semantic association of topic terms in networks between basic and applied topics. Simple fusion explicitly linked the topic terms, which can be used as automatic seed marking for subsequent link prediction to identify implicit linking of topic terms. Furthermore, an application to the gene-engineered vaccines field depicted that newly predicted implicit relations can effectively identify LTSTs. The results also show that implicit semantic recognition of LTSTs can be enhanced through simple fusion, while the recognition of LTST can be improved through link prediction. Therefore, the proposed model can assist experts to identify LTSTs that cannot be recognized through simple fusion. 相似文献
