Biometrics readers are deployed in many public sites and are used for user identification and verification. Nowadays, most biometrics readers can be connected to local area networks, and consequently, they are potential targets for network attacks. This article investigates the robustness of several fingerprint and iris readers against common denial of service attacks. This investigation has been conducted using a set of laboratory experiments and DoS attack generator tools. The experiments show clearly that the tested biometric readers are very vulnerable (...) to common DoS attacks, and their recognition performances deteriorate significantly once they are under DoS attacks. Finally, the article lists some security consideration that should be taken into consideration when designing secure biometrics readers. (shrink)

Drawing on frame semantics as a framework, the current article studies metaphoric and metonymic pseudonyms. The corpus is made up of 128 pseudonyms produced by Saudis over mass and social media. The argument runs as follows: Pseudonym Bearers use metaphor and/or metonymy as an Instrument to construct a pseudonymous frame to mask their identity. Sociocultural reality, which is called the Trigger of the frame, is the motivation behind conceptualizing the self via a pseudonym. The Goal of the pseudonym is to (...) change the Trigger and Benefit psychologically from this change. To measure this change of reality, the researchers submit the pseudonyms under study to Lakoff and Turner’s Great Chain of Being Metaphor. The findings of the article point to a scaling of the Bearer down the Chain, thus re-categorizing the self as less than human. These findings will be shown to occasion possible theoretical implications for the contemporary theory of metaphor. (shrink)

Using a sample of 15,174 firms from 24 countries included in the 2009 World Bank Enterprise Survey, we investigate the impact of disclosure standards and auditing infrastructure on the bribery of public officials to secure government contracts. We find that firms are less likely to grant gift to secure a government contract in countries having more extensive financial reporting requirements and countries where audit firms face a higher litigation and sanction risk. Findings also show that firms are less likely to (...) bribe bureaucrats in case financial statements are reviewed by an external audit firm. Our results are economically significant and are robust to several sensitivity analyses. These findings support certain policies that are currently being implemented or discussed to mitigate bribery within the public sector across the globe. (shrink)

Recent trends in linguistics and cognitive science reflect an increasing interest to explore the relationship between culture and language on the one hand, and the human mind and body on the other....
