Identifying Unethical Personally Identifiable Information (Pii) Privacy Violations Committed By Is/It Practitioners: A Comparison To Computing Moral Exemplars, Mark H. Rosenbaum

CCAC Theses and Dissertations

In some instances, Information Systems and Information Technology (IS/IT) practitioners have been noted to commit privacy violations to Personally Identifiable Information (PII). However, computing exemplars, due to their notable dispositional Hallmark Features of morality, understandings of ethical abstractions, and other components that comprise their virtuous makeups, are theoretically less likely to commit privacy violations to PII. This research attempted to verify if those IS/IT practitioners who identify with some of the Hallmark Features of moral and computing exemplar were less willing to commit privacy violations to PII than were those IS/IT practitioners that did not identify themselves with some of …

Implicit Measures And Online Risks, Lucinda W. Wang

CCAC Theses and Dissertations

Information systems researchers typically use self-report measures, such as questionnaires to study consumers’ online risk perception. The self-report approach captures the conscious perception of online risk but not the unconscious perception that precedes and dominates human being’s decision-making. A theoretical model in which implicit risk perception precedes explicit risk evaluation is proposed. The research model proposes that implicit risk affects both explicit risk and the attitude towards online purchase. In a direct path, the implicit risk affects attitude towards purchase. In an indirect path, the implicit risk affects explicit risk, which in turn affects attitude towards purchase.

The stimulus used …
