This paper attempts to examine the effects of virtual team dimensions on social identities of its members. A review of the literature shows that the geographically dispersed, culturally diverse as well as temporary dimensions of virtual teams do not match with their stability as members have different ethnic, social, or cultural backgrounds. Sources like culture, place, and time seem to continu...

Public-key based certificates provide a standard way to prove one's identity, as certified by some certificate authority (CA). However, standard certificates provide a binary identification: either the whole identity of the subject is known, or nothing is known. We propose using a Merkle hash tree structure, whereby it is possible for a single certificate to certify many separate claims or attr...

Complementary distribution stems from two sources. The first is a consequence of static lexical regularities such that two sounds never appear in the same context. The second is from dynamic alternations induced by morphological derivation. In this paper I provide evidence — from New York English, Akan, Madurese, and Malay — that these two sorts of relationship among sounds possess distinct pho...

In a laboratory investigation of a principal-agent relationship with moral hazard, we analyse strategically induced discrimination. We isolate the influence of the strategic environment from the e↵ects of other sources of discrimination, including group statistics and taste for discrimination. We find that, in a strategic setting, principals who reward agents contingent on agent-generated outco...

In this paper we present a novel technique for combining a Speaker Verification System with an Utterance Verification System in a Speaker Authentication system over the telephone. Speaker Verification consists in accepting or rejecting the claimed identity of a speaker by processing samples of his/her voice. Usually, these systems are based on HMM's that try to represent the characteristics of ...

The extent and sources of coarticulation remain an active topic of research. Whalen [18] found that vowel-to-vowel coarticulation occurred even when the utterance was initiated before an intervening consonant’s identity was known. Here, we address vowel-to-vowel coarticulation in the articulatory domain, replicating [18]. Spoken English nonsense strings [əәˈbVCɑ] were recorded with electromagne...

Speaker Verification and Utterance Verification are examples of techniques that can be used for Speaker Authentication purposes. Speaker Verification consists of accepting or rejecting the claimed identity of a speaker by processing samples of his/her voice. Usually, these systems are based on HMM models that try to represent the characteristics of the speakers’ vocal tracts. Utterance Verifica...

This paper is concerned with an extension of the well known KaluzaKlein mechanism. As the standard ansatz for Kaluza-Klein reduction implies the existence of a gauge potential associated with the KK field strength, it follows immediately that this field strength satisfies its Bianchi identity. Hence, the standard KK formalism breaks down in the presence of a violated Bianchi identity. This occu...
