Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

The asymptomatic osseous variation of postcranial skeleton : their contribution to the identification in forensic anthropology
No full textEn anthropologie médico-légale la détermination du sexe, l'estimation de l'âge au décès et l'estimation de la stature sont des paramètres essentiels à la constitution du profil biologique d'un individu à partir de restes osseux. Toutefois uniquement à partir de ces trois paramètres les interprétations sont limitées, plusieurs individus peuvent partager un même profil. L'introduction et l'observation d'autres paramètres, comme les variations anatomiques, peuvent être un atout dans l'établissement du profil biologique le plus singulier et complet possible afin de ne correspondre qu'à un nombre très restreint d'individus voire à un seul individu. En plus des variations anatomiques, l'observation des marqueurs de posture et des anomalies congénitales asymptomatiques peut aussi se révéler être pertinente. Ils ont été regroupés sous le terme de Variations Osseuses Asymptomatiques (VOA). Cent-neuf VOA ont été recensées sur le squelette postcrânien et 82 ont été étudiées à partir de 1300 individus provenant de trois populations différentes : une population contemporaine (imagerie médicale), une population ostéologique de référence et une population ostéoarchéologique. Pour chacune des VOA, la fréquence a été obtenue à partir des trois échantillons puis une fréquence en fonction du sexe, de l'âge et de la latéralité a été calculée. Une iconographie claire de chaque VOA a été obtenue. L'intérêt final est de ne sélectionner que les VOA ayant une fréquence inférieure à 10 % et facilement observables afin d'aider à l'identification en complétant le profil biologique, et ceci à partir d'une méthode basée sur la comparaison de données ante et post-mortem.In forensic anthropology, determination of sex, estimation of age at death and estimation of stature are essential parameters for constituting the biological profile of an individual from bone remains. However, using only three parameters limits interpretation, several individuals could share the same profile. The introduction and observation of others parameters, particularly anatomical variations, could help establish a more complete and specific biological profile to correspond to a restricted number of individuals or to a unique individual. In addition to anatomical variations, postural markers and congenital anomalies can be useful for identification purposes. These 3 elements are regrouped under the term Asymptomatic Osseous Variation (AOV). 109 AOVs were found on the postcranial skeleton and 82 were studied on 1300 individuals from three different populations: a contemporary population (medical imaging), an osteological collection of reference and an osteoarcheological population. Frequencies were obtained from the three samples for each AOV, and frequencies according to sex, age and laterality were calculated. A clear iconography of each AOV was obtained. This data enabled the classification of the AOVs according to 5groups of frequencies, ranging from very rare to very frequent. The AOVs were also classified according to their liaison with sex, age and laterality. The final goal is to select only AOVs with a frequency inferior to 10% (qualified as rare), that are easily observable, to be useful for establishing the biological profile and help identify the individual, using a method based on ante and post-mortem data comparison
