Beyond deterrence: an expanded view of employee computer abuse

Abstract: Recent academic investigations of computer security policy violations have largely focused on nonmalicious noncompliance due to poor training, low employee motivation, weak affective commitment, or individual oversight. Established theoretical foundations applied to this domain have related to protection motivation, deterrence, planned behavior, self-efficacy, individual adoption factors, organizational commitment, and other individual cognitive factors. But another class of violation demands greater research emphasis: the intentional commission of computer security policy violation, or insider computer abuse. Whether motivated by greed, disgruntlement, or other psychological processes, this act has the greatest potential for loss and damage to the employer. We argue the focus must include not only the act and its immediate antecedents of intention (to commit computer abuse) and deterrence (of the crime), but also phenomena which temporally precede these areas. Specifically, we assert the need to consider the thought processes of the potential offender and how these are influenced by the organizational context, prior to deterrence. We believe the interplay between thought processes and this context may significantly impact the efficacy of IS security controls, specifically deterrence safeguards. Through this focus, we extend the Straub and Welke (1998) security action cycle framework and propose three areas worthy of empirical investigation--techniques of neutralization (rationalization), expressive/instrumental criminal motivations, and disgruntlement as a result of perceptions of organizational injustice--and propose questions for future research in these areas.

Biomarkers of the intake of dietary polyphenols: strengths, limitations and application in nutrition research

Abstract: In order to establish firm evidence for the health effects of dietary polyphenol consumption, it is essential to have quantitative information regarding their dietary intake. The usefulness of the current methods, which rely mainly on the assessment of polyphenol intake using food records and food composition tables, is limited as they fail to assess total intake accurately. This review highlights the problems associated with such methods with regard to polyphenol-intake predictions. We suggest that the development of biological biomarkers, measured in both blood and urine, are essential for making accurate estimates of polyphenol intake. However, the relationship between dietary intakes and nutritional biomarkers are often highly complex. This review identifies the criteria that must be considered in the development of such biomarkers. In addition, we provide an assessment of the limited number of potential biomarkers of polyphenol intake currently available.
