Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
La gestion de l'eau dans la civilisation de l'Indus (2500-1900 av. n. è.) : techniques, milieux et société(s)
No full textThis doctoral thesis focuses on water management during the Indus civilisation (2500-1900 BCE). This major cultural complex of the Bronze Age, spanning present-day Pakistan and north-west India, was behind the emergence and development of the first cities in South Asia. Spread across a geographical area that features a wide variety of ecosystems and contrasting water resources, these settlements were associated with a wide array of agricultural and urban hydraulic techniques implemented by ancient populations. Although a considerable amount of research has recently been carried out on the environment and water resources, hydraulic structures have only been investigated at a few sites (Mohenjo-daro, Dholavira). Based on an examination of ancient excavations and new fieldwork carried out at Chanhu-daro, Sindh, this research has made it possible to establish a corpus detailing 597 hydraulic structures in a systematic manner. Covering twelve sites and five distinct regions, this corpus provides the basis for the first comprehensive overview of hydraulic structures in Indus Civilisation, analysing their contexts, typologies, materials and, above all, their functions (water supply, water storage, water use and sanitation). By examining the spatial distribution of these structures (intrasite, intersite) and their chronostratigraphy, this study aims to provide new insights into their emergence and spread throughout the ‘Greater Indus Valley’, while exploring their implications for urban processes. Finally, by investigating the complex relationships between techniques, environments and the social dynamics of the various regions that comprise the Indus basin, this research seeks to contribute to ongoing debates on the cultural diversity and identity of this civilisation.Ce travail doctoral porte sur la gestion de l’eau dans la civilisation de l’Indus (2500-1900 av. n. è.). Cet ensemble culturel majeur de l’âge du Bronze, qui s’étend l’actuel Pakistan ainsi que le nord-ouest de l’Inde, est à l’origine de l’apparition et du développement des premières villes de l’Asie du sud. Réparties au sein d’un espace géographique qui présente une grande variété d’écosystèmes et dont les ressources en eau sont contrastées, ces villes s’accompagnent d’un large éventail de techniques hydrauliques agricoles et urbaines, mises en place par les populations anciennes. Bien que de nombreuses recherches aient récemment été conduites sur l’environnement et les ressources en eau, les structures hydrauliques n’ont fait l’objet que d’études limitées à quelques sites (Mohenjo-daro, Dholavira). À partir de l’examen des fouilles anciennes, et d’un travail de terrain effectué à Chanhu-daro dans la région du Sindh, il a été possible d’établir un corpus détaillant 597 structures hydrauliques de manière systématique. Couvrant douze sites et cinq ensembles régionaux distincts, il permet d’établir les bases d’une première synthèse complète sur les structures hydrauliques de l’Indus en prenant soin d’analyser leur contexte, leur typologie, leurs matériaux et surtout leur fonction (approvisionnement, stockage, usage de l’eau et assainissement). En examinant la répartition spatiale des structures (intrasite, intersite) et leur chronostratigraphie, il s’agira d’apporter un nouvel éclairage sur leur apparition et leur diffusion dans l’ensemble de la vallée de l’Indus, tout en interrogeant leur implication sur l’évolution des modes de vie urbains. Enfin, en questionnant les relations complexes entre les techniques, les milieux naturels et les dynamiques sociales des différentes régions qui composent le bassin de l’Indus, cette recherche propose d’apporter une contribution aux débats contemporains portant sur la diversité culturelle et la nature de cette civilisation
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
