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
Edilizia rurale e tradizione agricola in Puglia. I frantoi oleari
No full textI fabbricati rurali si sono evoluti nel rispetto dei caratteri territoriali naturali e culturali consolidando un rapporto simbiotico nel quale entrambe le componenti – fabbricati e territorio – si sono reciprocamente influenzate nel rispetto di rapporti funzionali essenziali per l’espletamento delle attività agricole. La variabilità dei contesti rurali e la diversificazione delle possibili attività produttive hanno così conferito alle costruzioni rurali poliformismo e multifunzionalità definendo specifici rapporti tra forme architettoniche e funzioni. Per ricchezza e differenziazione tipologica l’architettura rurale minore meriterebbe un maggiore interesse da parte delle politiche territoriali che dovrebbero colmare preliminarmente la conoscenza per poi procedere con politiche di tutela e valorizzazione
Tra le diverse tipologie “minori” di tipo strumentale i frantoi costituiscono l’emblema della cultura olivicola olearia delle regioni meridionali ed in particolare della regione Puglia che senza ombra di dubbio costituisce uno dei più importanti areali olivicoli nazionali
L’indagine condotta ha consentito di inquadrare i frantoi storici dispersi nel territorio regionale delineandone l’evoluzione storica delle strtture che gradualmente hanno abbandonato il sottosuolo (frantoi ipogei) per emergere in superficie in forme più razionali (semi ipogei e fuori terra) sia nei centri urbani sia nel territorio rurale. Si è comunque evidenziato che il consistente patrimonio architettonico oleario pugliese è in realtà misconosciuto pur rappresentando inconfutabilmente una risorsa diffusa e variegata. Le lacune evidenziate nelle fonti cartografiche richiederebbero degli studi finalizzati a colmare tale deficit conoscitivo anche al fine di prospettare doverose politiche di tutela e valorizzazione.
Gli interventi di tutela e valorizzazione non possono comunque prescindere da ipotesi di riqualificazione in grado di assegnare nuove attribuzioni funzionali - essendo venuta meno quella produttiva - attraverso la rilettura del mutato contesto territoriale
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
[CT and MR virtual colonscopy: indications, limits and comparison with conventional colonscopy].
No full textVirtual endoscopy is a new method for studying the colon; it consists in acquisition of CT and MR images and to elaborate them with a workstation, to create endoluminal vision as like as traditional colonscopy, permitting the complete exploration of colonic lumen, also with stenotic tumors. The analysis of the differences between CT and MR colography shows like these two techniques present both advantages and disadvantages, such as the impossibility to perform MR in patients with pace-maker or in claustrophobic patients and the impossibility to perform CT with iodated agents in patients with renal failure or with a story of adverse reactions. The increased use of these techniques is due to the high sensitivity of last-generation CT and MR machine, to the increased spatial resolution, to specific softwares for digital cleaning of colon, to the introduction of high-end workstations and to the possibility of computed assisted diagnosis (CAD). So, it is desiderable that the increasing spread of multidetector CT devices and the future technical innovations, should have the effect to increase culture and experience in various diagnostic centers about CT-colography, making possible the spreading of virtual endoscopy as a screening tool
