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
A critical review of the anthropological and paleopathological literature on osteopetrosis as an ancient rare disease (ARD)
Full text linkObjective: A reappraisal of the available evidence of osteopetrosis in the archaeological record as first step in promoting new approaches to rare diseases in paleopathology.Materials and methods: Three different approaches are combined: a survey of the last 50 years of bioarchaeological publications; an online search addressing six of the more widely used search engines; macroscopic and radiographic analyses of the human remains from the Neolithic site of Palata 2 (Italy). Results: The combined results of the literature survey and the online search identified six cases of osteopetrosis. The majority of search hits place this disease into differential diagnoses. The investigation of the remains from Palata 2, one of the six cases in literature, indicates a non-specific sclerosis of the cranial vault.Conclusions: Of the six cases of osteopetrosis, only two, one of the autosomal-recessive type (ARO) and one of the autosomal-dominant type (ADO), are supported by direct osteoarchaeological evidence. Therefore, inaccurate differential diagnoses generate an inflated number of cases in the paleopathological record.Significance: This reappraisal calls for a more informed and evidence-based approach to osteopetrosis and, more generally, to rare diseases in paleopathology.Limitations: Lack of specific publications on osteopetrosis; more case studies may be present in "gray literature". Suggestions for further research: Cases of osteopetrosis from archaeological and historical collections as well as medical literature are needed to increase knowledge about this rare disease. More precise differential diagnoses are required, particularly when dealing with rare diseases
Il “margine” come ordinata estetica di un edificio urbano. La Caserma “G. Macchi”
No full textTra i tanti neologismi che oggi pervadono nel campo dell’architettura, quello di “paesaggio urbano” è sicuramente tra i più utilizzati. Esso, sebbene chiaramente afferente ad una dimensione di carattere figurativo-percettiva della città, ad una sfera di giudizi condizionati dai continui rimandi al dato sensibile e sensoriale del termine paesaggio, di fatto non può trascendere da questioni di natura compositiva inerenti la struttura formale dei tessuti urbani. Ciò significa che la comprensione di un paesaggio urbano andrebbe perseguita attraverso il tramite di un arnheimiano “pensiero visuale”. Ossia per mezzo di categorie cognitive in grado di generare un racconto critico-sintetico finalizzato alla ricerca di una idea regolatrice e vettrice utile a rivelare, delle singole esperienze “architetturali”, una ragione urbana intenzionale, di natura strutturale-compositiva nonché spaziale.
Una delle “ordinate estetiche” attraverso le quali risulta possibile cogliere il senso profondo del paesaggio urbano in cui si colloca l’edificio della Caserma Macchi si identificarsi nel concetto di “margine”. Una nozione che consente di allargare la riflessione, in senso lato, sul tema del progetto di composizione di un “bordo” urbano. Un luogo, quest’ultimo, dove all’esperienza del progetto urbano è richiesta la capacità di destreggiarsi tra il tentativo di stabilizzare il disegno della forma urbana sui cui contorni si interviene, e, il riuscire a stabilire nuove relazioni con ciò che si pone al di fuori, nell’immediata prossimità. Nel caso specifico della Caserma Macchi (e degli altri edifici più o meno coevi così come ipotizzati dal piano redatto dall’ing. Arrigo Veccia tra il 1905 e il 1926), l’esperienza del progetto del margine, in quanto costruzione del “fronte mare” della città, è diventata per l’architettura del ventennio barese l’occasione per sancire il rapporto tra la città e la linea del mare, tra la dimensione costruita della terra e la dimensione sconfinata dell’acqua.
Un tipo di “paesaggio urbano di margine” qualificato dal carattere mediterraneo, stereotomico e variegato delle architetture che lo identificano e lo delimitano, al punto da renderlo chiaramente riconducibile ad un “paesaggio di soglia”: un vero e proprio ambito urbano a sviluppo lineare, connotato da una forte identità architettonico-culturale, interposto tra la città compatta e il mare
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
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
