Burrows’s Delta is the most established measure for stylometric difference in literary authorship attribution. Several improvements on the original Delta have been proposed. However, a recent empirical study showed that none of the proposed variants constitute a major improvement in terms of authorship attribution performance. With this paper, we try to improve our understanding of how and why ...

Authorship guidelines have established criteria to guide author selection based on significance of contribution and helped to define associated responsibilities and accountabilities for the published findings. However, low awareness, variable interpretation, and inconsistent application of these guidelines can lead to confusion and a lack of transparency when recognizing those who merit authors...

With such increasing popularity and availability of digital text data, authorships of digital texts can not be taken for granted due to the ease of copying and parsing. This paper presents a new text style analysis called natural frequency zoned word distribution analysis (NFZ-WDA), and then a basic authorship attribution scheme and an open authorship attribution scheme for digital texts based ...

OBJECTIVE To identify changing trends in female authorship and publication in the otolaryngology literature. METHODS All articles published in the four major otolaryngology journals in each of the years 1978, 1988, and 1998 were reviewed. The authorship panel of each article was examined for number of authors, gender, educational degree category, and subspecialty area of publication. Data wer...

Hamilton (1) argued that prior to his theory of inclusive fitness, nobody had sought evidence for kin discrimination in animals because nepotism was an embarrassment to human society. Why did it take so long after Hamilton’s theory was proposed, however, to search for kin discrimination in simpler organisms, like bacteria? Perhaps we were prideful that we, as animals, have the unique ability to...

Sex differences in the salience and meaning of kin relations for contemporary Canadians were examined in two studies. In study 1, 24 opposite-sex adult sibling pairs were asked to reconstruct their kindreds as fully as possible, following a computerized menu. Sisters almost invariably recalled more relatives than did their brothers, especially living and matrilateral relatives. In study 2, a qu...

Recently, Herranz presented an identity-based ring signature scheme featuring signer verifiability where a signer can prove that he or she is the real signer by releasing an authorship proof. In this paper we show that this scheme is vulnerable to a key recovery attack in which a user’s secret signing key can be efficiently recovered through the use of two known ring signatures and their corres...

Are simple strokes unique to the artist or designer who renders them? If so, can this idea be used to identify authorship or to classify artistic drawings? Also, could training methods be devised to develop particular styles? To answer these questions, we propose the Stroke Authorship Recognition (SAR) approach, a novel method that distinguishes the authorship of 2D digitized drawings. SAR conv...
