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
Scrivere come un uomo, scrivere come una donna: il conflitto identitario in Natalia Ginzburg
Get PDFIl capitolo intende fare luce sul complesso rapporto tra volontà di aderire a modelli maschili e desiderio di scrittura femminile nell’opera di Natalia Ginzburg e su come questo conflitto si rifletta sulle sue scelte di editrice einaudiana. Ginzburg è una figura emblematica della condizione di marginalità del lavoro delle donne, che sono protagoniste, al tempo stesso, di un lento ma significativo processo di emancipazione. Non mancano, all’interno della lunga carriera editoriale di Ginzburg, momenti rivelatori di tale complesso processo. Il capitolo si prefigge inoltre di rileggere il percorso autoriale di Ginzburg alla luce del conflitto identitario che emerge nelle sue scelte poetiche tra gli anni ‘40 e ’50. Nel corso della sua maturazione artistica, Ginzburg acquisisce la consapevolezza della propria identità e si affranca dal desiderio di “scrivere come un uomo”, a più riprese dichiarato, mantenendo tuttavia un rapporto complesso e a tratti oppositivo con la “questione femminile”.This chapter aims to shed light on the complex relationship between the desire to conform to male models and the yearning for female writing in Natalia Ginzburg’s narrative and non-fiction work and how this conflict is reflected in her choices as editor at Einaudi. Ginzburg is an emblematic figure of the marginalized condition of women’s work, which, at the same time, undergoes a slow but significant process of emancipation. Her long career in publishing offers many moments that reveal this complex process. The chapter also intends to reexamine Ginzburg’s path as an author in light of the identity conflict that emerges from her poetic choices between the 1940s and 1950s. During her artistic maturation, Ginzburg gained an awareness of her identity and freed herself from the repeatedly declared desire to “write like a man”, while maintaining a complex and sometimes conflicting relationship with the issues brought up by feminist movements
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
Cancer Stem Cells and the Tumor Microenvironment: Soloists or Choral Singers
No full textAlthough not a new concept, the idea of cancer stem cell (CSC) has recently moved to the forefront of cancer research. There is still a lack of a widespread consensus on their description and definition, however, and the increasing literature on CSCs has compelled researchers worldwide to rewrite the natural history of cancer including those cells as principal players as well as to revise their views on tumor formation and progression. CSCs are tumor cell components that can initiate a new tumor after an apparent therapeutic eradication. A functional definition of cancer stem cell or cancer initiating cell is that of a cell which, when transplanted in a mouse model, can give rise to a tumor recapitulating the original one or even a phenotypically diverse tumor related to the tumor of origin. Since the characteristic asymmetric division of stem cells is somewhat anomalous, it might be advisable to refer to them as "stemloids". Stemness in cancer is not as much as an identity but rather a status. There is increasing evidence of the importance of the tumor and the host micro-environment in conditioning the stem cell status itself. The cancer stem cell micro-environment may be the key in the development of therapeutic strategies. We must think in terms of targeting "standard" tumor cells, cancer stem cells, and also their niche or micro-environment. Here we discuss some features of cancer stem cells, and the role of the micro-environment, envisaging a choral view of cancer stem cell development and-or latency, towards development of specific therapeutic approaches
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
