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
Caratteristiche neuroradiologiche dell’emicrania oftalmoplegica: descrizione di un caso pediatrico
No full textSCOPO DEL LAVORO L’emicrania oftalmoplegica è definita come la paralisi di uno o più nervi cranici oculomotori che insorge durante o dopo un attacco di emicrania. Tratto distintivo di questa patologia è l’oftalmoplegia, con dolore retro o sopraorbitale, associata spesso a nausea e vomito. Cessata la cefalea, l’oftalmoplegia può durare per alcuni giorni e poi scomparire, ma dopo molti attacchi può persistere la paresi del muscolo extraoculare. Lo scopo di questo lavoro è quello di descrivere le caratteristiche neuroradiologiche tipiche dell’emicrania oftalmoplegica in un caso pediatrico. MATERIALI E METODI Si descrive il caso di un bambino di 9 anni che accede in pronto soccorso per insorgenza acuta di cefalea, diplopia e ptosi palpebrale all’occhio destro. All’ingresso viene eseguito esame obiettivo, TC cranio e RM encefalo con mezzo di contrasto (1.5T). Esegue RM di controllo a 2,12 e 24 mesi. RISULTATI Il Paziente si presenta sofferente, con riferita cefalea da qualche giorno, seguita dalla comparsa di diplopia e ptosi palpebrale destra. La TC e l’RM documentano ispessimento dell’emergenza del III nervo cranico di destra, caratterizzato da enhancement post-contrastografico dopo somministrazione di chelati del gadolinio. Trattato con terapia cortisonica, il bambino ha mostrato progressivo miglioramento clinico- radiologico, con pressochè completa regressione della sintomatologia e dell’enhancement nelle RM di controllo, pur mantenendosi l’ispessimento del nervo. I reperti descritti sono compatibili con diagnosi di emicrania oftalmoplegica in accordo a quanto descritto in letteratura. L’emicrania oftalmoplegica è un quadro clinico-radiologico caratterizzato da cefalea del tipo emicrania accompagnata o seguita nei giorni successivi da paresi di uno o più tra III, IV e/o VI nervo cranico, spesso reversibile e autolimitante. Tipicamente nel bambino, durante la fase acuta, la RM mostra ispessimento rotondeggiante o trapezoide e omogeneo enhancement del tratto cisternale del nervo coinvolto (di solito il III nervo cranico), con risoluzione pressoché completa dell’enhancement nel periodo quiescente. Tali reperti RM sono sostenuti dal fatto che l’attacco emicranico innescherebbe vasospasmo dei vasa nervorum con conseguente alterazione della barriera emato-encefalica (immatura e poco efficiente specie nel bambino e nella zona di emergenza del nervo). CONCLUSIONI L’emicrania oftalmoplegica è un quadro clinico-radiologico caratteristico a prognosi buona e autolimitantesi. La RM è una metodica di imaging fondamentale per la diagnosi di tale condizione. La conoscenza dei reperti tipici è importante per la corretta pianificazione terapeutica
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
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
