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
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
Agricoltura, alimentazione e paleoambiente della Jazira siriana tra IV e III mill. a.C. Le evidenze da Tell Mozan
Get PDF[Italiano]: Il volume presenta nuove informazioni sul rapporto che la comunità antica insediata nella regione attraversata dall’Alto Khabur, nella Siria nordorientale, instaurò con l’ambiente nel quale era inserita. A tal fine, ci si è avvalsi di un approccio interdisciplinare che ha consentito di tracciare una parte dell’evoluzione del mondo vegetale, mediante lo studio dei resti di semi e frutti provenienti dagli scavi archeologici di Tell Mozan, diretti da Giorgio Buccellati e Marilyn Kelly-Buccellati dell’IIMAS – The International Institute of Mesopotamian Area Studies. I livelli indagati da questa ricerca sono riferibili a due fasi cronologiche distinte, Late Chalcolithic 3 (prima metà del IV mill. a.C.) e Early Jazirah IV (seconda metà del III mill. a.C.).
I campioni analizzati hanno restituito un assemblaggio carpologico costituito per la maggior parte da un complesso di cariossidi di cereali, perlopiù frammentarie, scarsissimi resti di spighetta e di spiga, una gran quantità di piante infestanti, soprattutto graminacee e, in misura minore, infestanti leguminose e infestanti relative ad altre famiglie. Le piante coltivate maggiormente attestate nel sito di Tell Mozan sono rappresentate dai cereali quali orzo, dicocco e grani nudi; di gran lunga inferiori sono le attestazioni di legumi, in particolare la lenticchia, e dei frutti, tra i quali un interessante presenza è quella della vite nei livelli del III mill. a.C. Molto numerosa è la documentazione delle piante infestanti, soprattutto graminacee, in molti casi Aegilops e, in misura minore, infestanti leguminose e di altre famiglie.
Nei modelli elaborati, mediante studi etnografici, per la ricostruzione delle fasi di lavorazione dei cereali, il complesso vegetale rinvenuto nei livelli di IV mill. a.C. potrebbe essere correlato alla fase della trebbiatura, mentre quello ritrovato nei campioni di III mill. a.C. potrebbe essere collegato a uno degli stadi finali della lavorazione, compreso tra la setacciatura fine dei grani e il loro primo stoccaggio. Il prodotto di questo stoccaggio, rinvenuto nell’area identificata come magazzino reale, poteva essere destinato all’alimentazione animale piuttosto che a quella umana. Una delle prime deduzioni di carattere ecologico che lo studio di questi resti consente di trarre è che la caratteristica comune a gran parte delle infestanti identificate è quella di potersi insediare in habitat aperti, come campi coltivati o margini di campi coltivati. Inoltre, la presenza di piante tipiche di aree incolte umide, come stagni o corsi d’acqua ha permesso di definire aspetti del paesaggio naturale.
La ricerca, quindi, integrando le informazioni provenienti da fonti archeologiche e archeobotaniche, ha consentito di ricostruire il quadro del paesaggio ecologico e culturale di una parte della Jazira siriana sul finire della protostoria. La definizione dell’archivio biologico del sito di Tell Mozan potrà, inoltre, fornire un apporto fondamentale per la realizzazione di una riserva di biodiversità, nella quale custodire la storia del rapporto della comunità che popolava la Jazira siriana del passato con l’ambiente. / [English]: The volume presents new information about the peculiar relationship between the ancient communities settled the Upper Khabur region, in northern Syria and their own environment. In order to achieve this goal, an interdisciplinary approach has been adopted, which has shed light on the evolution of the plant world, through the study of the archaeological plant remains from the excavation carried out at the site of Tell Mozan, under the auspice of IIMAS – The International Institute of Mesopotamian Area Studies by Giorgio Buccellati and Marilyn Kelly-Buccellati. The samples here investigated belong to two different chronological periods, Late Chalcolithic 3 (the first half of the 4th millennium BC) and Early Jazira IV (the second half of the 3rd millennium BC).
The carpological record is mainly made up of mostly fragmentary cereal grains, few spike and spikelet remains, a large number of weeds, especially of graminaceous family, and, in a smaller amount, of leguminous family and of other families. Crops are characterized by whole and fragmentary grains and by few spike remains of barley, einkorn, emmer, and free threshing wheat. The pulse remains, mainly lentil, and fruit remains are far fewer and among the latter grapevine remains from 3rd millennium BC levels are remarkable. Weeds were found in all samples in high percentages; among the most representative families, the graminaceous family (Poaceae) is to be noticed, in particular Aegilops. Leguminous weeds (Fabaceae) and other weed families have been found in lower percentages.
According to ethnographic studies of various cereal-processing stages, plant complex from 4th millennium BC levels may be related to threshing waste, while that from 3rd millennium BC levels may be linked to a final phase of processing, between the fine sieving of grains and their first storage. This product, retrieved from the area identified as the royal storehouse, seems to be also connected to the phase of food preparation for animal feed rather than for human consumption. As far as the ecological perspective is concerned, the study of these remains leads to the conclusion that most of the weeds found here can grow in open habitats such as cultivated fields or margins of cultivated fields and, to a lesser extent, in uncultivated areas, among which wet areas, such as ponds or watercourses are to be found.
Thus, the ecological and cultural landscape of a part of the past Syrian Jazira during the late prehistory has been reconstructed, by integrating the information coming from the archaeological contexts and archaeobotanical remains. The definition of the biological archive of the site can also provide an important contribution to the realization of a biodiversity reserve in which to preserve the history of the man-environment relationship in this area

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
