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
Allevamento e macellazione del suino pesante: correlazione tra la qualità della carne e il grado di benessere (Correlation between meat quality and welfare level: the case of italian heavy pigs)
No full textScopo della presente ricerca è stato quello d’indagare le relazioni esistenti fra il benessere degli animali durante le fasi di allevamento e trasporto e la qualità delle carni da essi ottenute.
La sperimentazione è stata condotta su 44 partite di suini pesanti provenienti da 11 allevamenti siti in Emilia Romagna e selezionati casualmente. Il benessere animale è stato valutato dal Centro Ricerche e Produzioni Animali (CRPA) di Reggio-Emilia attraverso un sistema da loro implementato: per ogni allevamento è stato calcolato l’Indice di Benessere dell’Allevamento (IBA) e per ogni partita di macellazione l’Indice di Benessere del Trasporto e della pre-Macellazione (IBTM). Da 440 animali (10 per partita) è stato prelevato un campione di sangue alla giugulazione su cui sono state determinate le concentrazioni di creatinchinasi (CK), aldolasi e cortisolo. Dai medesimi animali sono stati poi prelevati campioni di lombo su cui sono stati misurati pH, colore strumentale, potere di ritenzione idrica e resistenza al taglio.
I risultati dell’analisi statistica hanno evidenziato che il miglioramento del benessere influenza in positivo la qualità della carne: in tal senso l’effetto più importante non è dovuto alle condizioni d’allevamento, bensì a quelle di trasporto e macellazione. Nello specifico i punti critici individuati dal nostro studio sono rappresentati dal prolungamento del tempo di trasporto e dalla commistione di animali provenienti da gruppi sociali diversi.The present study investigated the relationships between the welfare of pigs (on farm, during transport and before slaughtering) and the quality of the derived meat.
The experimental trial was carried out on 44 slaughtering batches of heavy pigs, coming from 11 farms located in Emilia Romagna and randomly selected. Animal welfare was assessed by the Research Centre on Animal Production (Italian initials CRPA) of Reggio Emilia, according to a welfare assessment protocol they have implemented. According to this protocol, each farm was scored for the Farm Welfare Index (Italian initials IBA), and each slaughtering batch was scored for the Transport and pre-Slaughter Welfare Index (Italian initials IBTM).
Blood samples were collected upon exsanguination from 440 pigs (10 per slaughtering batch). Cortisol, creatinkinase (CK) and aldolase concentrations were analyzed on plasma. Loin samples were collected from the same animals, and used for meat quality evaluations (pH, instrumental colour, water holding capacity, shear force).
The results of the statistical analysis underlined that an increase in welfare level had a positive effect on meat quality; transport and pre-slaughtering procedures had the most important effects, whereas the level of welfare on farm had a lower effect. The critical points observed in this study were represented by the increase in journey duration and the mixing of pigs from different social groups during transport and lairage
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
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

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.
