Researchers have been closely studying how information technology services became a routine part of our lives. Studies have found that users who routinely use online services either consciously develop loyalty or automatically develop a habit. But many studies now mix the elements of conscious and automatic use despite the great differences in these phenomena. This study proposes a new theoretical...
In the context of field testing (operational testing) of software, we address the problem of balancing the potential reduction in failure risk that developers may achieve by reviewing captured test executions to identify failures (and by successfully debugging their causes) against the cost of reviewing the tests. To achieve a desirable balance, we propose a cost-sensitive active learning strategy...
Security researchers agree that security control is a difficult to observe credence quality of online services that Internet users cannot easily assess through research or experience. Yet there is evidence that users form perceptions of security control that strongly determine how much trust they put in online services. This study investigates whether users’ security control perceptions arise solely...
Previous work has shown that application of graph mining techniques to system dependence graphs improves the precision of automatic defect discovery by revealing subgraphs corresponding to implicit programming rules and to rule violations. However, developers must still confirm, edit, or discard reported rules and violations, which is both costly and error-prone. In order to reduce developer effort...
