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
Analysis on unilateral hearing loss: a monocentric retrospective study of correlations between aetiology, severity, evolution and hearing aid usage in 159 patients
No full textreservedIntroduzione. L’ipoacusia monolaterale (UHL) infantile è una patologia di comune riscontro negli ambulatori di Audiologia. I bambini che ne sono affetti sono stati inclusi con crescente interesse all’interno di studi mirati a testare le differenze tra essi e quelli affetti da ipoacusia bilaterale (BHL) e normoacusici. Sono state riscontrate differenze nell’eziologia, nei percorsi diagnostici e nelle opportunità di riabilitazione. Al contempo, questa condizione, non evolvendo nel drammatico deficit nella sfera del linguaggio tipico della BHL, è stata oggetto di un’iniziale carente attenzione da parte dei medici. Con le evidenze attuali, si può affermare che un solo orecchio sano non sia sufficiente per un corretto sviluppo linguistico e che il deficit monolaterale inveterato comporti sequele anche negli ambiti accademico e sociale. Questi bambini beneficiano particolarmente dello screening uditivo neonatale, che intercetta l’ipoacusia ed evita che si mantenga celata fino all’età scolare, quando arriverà a manifestarsi con i problemi suddetti. Questo studio mira a descrivere una popolazione di bambini affetti da UHL in trattamento presso l’Azienda Ospedaliera di Padova in termini di: entità dell’ipoacusia, evoluzione, eziologia e guadagno protesico.
Metodi e Materiali. È stata condotta un’analisi descrittiva di 159 pazienti con UHL, diagnosticati prima dei 18 anni di età, tra il 2003 e il 2023. Successivamente, su 93 di questi pazienti con dati di evoluzione disponibili, è stata eseguita un’analisi di regressione univariata e multivariata per identificare associazioni tra caratteristiche, quali eziologia dell’ipoacusia, peggioramento e guadagno protesico.
Risultati. L’età mediana dei pazienti alla diagnosi era di 9,7 mesi (IQR 3,5; 70,8). La soglia audiometrica (PTA4) mediana alla diagnosi era di 75,0 dB (IQR 55,0; 95,0) con il 44% che presentava un’ipoacusia profonda o totale. Al controllo, dopo un periodo mediano di 32,2 mesi (IQR 10,8; 64,1), la soglia mediana era di 72,5 dB (IQR 51,3; 95,0). Il miglioramento veniva riscontrato nel 26,9% dei casi (mediana –20,0 dB; IQR –30,0; –10,8), mentre il peggioramento nel 21,5% (mediana 15,6 dB; IQR 10,0; 22,8). Le cause di ipoacusia erano suddivise in cinque categorie: genetica (0,6%), infettiva (16,4%), malformativa (23,3%), multifattoriale (22,6%), sconosciuta (37,1%). La protesizzazione era stata adottata solo per il 24,5% dei pazienti e principalmente mediante apparecchio acustico, i cui portatori avevano un significativo guadagno protesico. Incrociando queste variabili si sono ritrovate entità mediane di miglioramento maggiori per l’ipoacusia da causa infettiva e di peggioramento maggiori per l’ipoacusia da causa malformativa. Mediante l’analisi univariata, nessuna variabile studiata ha mostrato una correlazione con l’evoluzione quantitativa; ma, il tipo di ipoacusia neurosensoriale, la soglia alla diagnosi, l’intervallo diagnosi-controllo e l’eziologia multifattoriale si sono rivelati predittori significativi della soglia uditiva al controllo. Infine, l’analisi multivariata ha mostrato la predittività del lato destro di ipoacusia, della soglia alla diagnosi e dell’eziologia multifattoriale per la soglia al controllo.
Conclusioni. L’ipoacusia infantile monolaterale richiede un’attenzione particolare in ambito clinico. In attesa della redazione di linee guida italiane per la gestione specifica di questi bambini, ulteriori dati sull’entità, l’evoluzione, l’eziologia e il guadagno protesico devono essere raccolti col fine di orientare il percorso assistenziale sia sulle caratteristiche individuali sia sui marcatori di predittività della popolazione di bambini affetti.Introduction. Unilateral hearing loss (UHL) in children is a common condition in Audiology clinics. Increasing interest has been directed towards comparison studies with children with bilateral hearing loss (BHL) or normal hearing. Some differences have been observed in aetiology, diagnostic pathways and rehabilitation chances. Initially, this condition received little clinical attention because it does not lead to the severe language deficits typical of BHL. Current evidence, however, indicates that one healthy ear is not sufficient for proper linguistic development and that longstanding unilateral losses have repercussions in the academic and social domains. These children particularly benefit from newborn hearing screening, which detects early hearing loss and prevents it from remaining undiagnosed until school age, when the issues become apparent. This study aims to describe a population of children with UHL being treated at the Padova University Hospital in terms of severity of hearing loss, progression, aetiology and aid gain.
Methods and Materials. A descriptive analysis was conducted on 159 patients with UHL, diagnosed before 18 years of age, between 2003 and 2023. Subsequently, a univariate and multivariate regression analysis was performed on 93 of these patients with available progression data to identify associations between characteristics such as type of hearing loss, aetiology, progression and aid gain.
Results. The median age at diagnosis was 9.7 months (IQR 3.5; 70.8). The median audiometric threshold (PTA4) at diagnosis was 75.0 dB (IQR 55.0; 95.0), with 44% presenting with profound or total hearing loss. At follow-up, after a median period of 32.2 months (IQR 10.8; 64.1), the median threshold was 72.5 dB (IQR 51.3; 95.0). Improvement was observed in 26.9% of cases (median –20.0 dB; IQR –30.0; –10.8), while deterioration occurred in 21.5% (median 15.6 dB; IQR 10.0; 22.8). The causes of hearing loss were categorized into five groups: genetic (0.6%), infectious (16.4%), malformative (23.3%), multifactorial (22.6%), and unknown (37.1%). Prosthetic fitting was adopted in only 24.5% of patients, primarily through conventional hearing aids, which showed significant gain for users. Greater median improvement was found for hearing loss due to infectious causes, while greater median deterioration was associated with malformative causes. Univariate analysis showed no variable correlated with quantitative progression; however, sensorineural hearing loss, threshold at diagnosis, diagnosis-to-follow-up interval and multifactorial aetiology were significant predictors of the hearing threshold at follow-up. Multivariate analysis revealed that right-sided hearing loss, threshold at diagnosis, and multifactorial aetiology were predictive of the follow-up threshold.
Conclusions. Unilateral hearing loss in children requires specific clinical attention. To develop national guidelines for the management of these children, further data on severity, progression, aetiology, and aid gain are needed to guide health care pathways, taking into account individual characteristics and predictive markers of the affected population

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.
