Respiratory function assessment at the time of a new respiratory virus pandemic
Full text linkWe must be aware that new respiratory virus pandemic can happen frequently. Standard lung function tests should keep their crucial role to assist the clinicians in the decision-making process, but they are at risk for the spread of infection because of the generated droplets. We used opto-electronic plethysmography to investigate the post-COVID-19 syndrome on 12 patients after ICU. We found normal ventilatory pattern at rest, a restrictive pattern located in the ribcage during vital capacity and surgical mask to significantly increase minute ventilation. The attention on unconventional respiratory function tests should be sponsored for the important information they can provide
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
Necropoli dell’Isola Sacra. Le ricerche 1968-89 : ripercorrendo un’esperienza
No full textL’articolo ripercorre metodi, problematiche e risultati delle ricerche condotte nella necropoli dell’Isola Sacra (1968-1989) sotto la direzione di I. Baldassarre, con lo scopo di giungere a una lettura in chiave antropologica di una necropoli romana di età imperiale a partire dalla documentazione archeologica. La necropoli si sviluppa ai due lati di una strada (seconda metà del I sec. d.C.) alla quale le tombe fanno riferimento con una costante ricerca di visibilità. Lo studio ha permesso di ricostruire modi e tempi dell’occupazione dello spazio funerario da parte delle singole tombe che si addossano le une alle altre creando l’immagine di edificazioni per gruppi unitari. Si tratta di tombe familiari, la cui funzione risulta dall’apparato epigrafico, dai dispositivi per i rituali funerari, dalla scarsità di materiali di corredo, che appaiono piuttosto in relazione a sepolture individuali, più « povere », che affollano tutti gli spazi liberi tra le tombe a cella. La ricerca ha anche messo in luce il ruolo chiave degli apparati figurativi e lo strutturarsi di un repertorio di decorazione funeraria, tema di particolare interesse per il ceto libertino che seppellisce nella necropoli. Nel quadro del crescente interesse per l’ideologia funeraria romana e riproponendo la storia di una ricerca nata molti anni fa in una Università piena di stimoli, l’articolo intende evidenziare quanto un contesto affrontato nella sua globalità possa contribuire ad approfondire la discussione relativa a questi temi.The article reviews methods and results of the research conducted at the Isola Sacra necropolis (1968-1989) under the direction of I. Baldassarre, with the aim of producing an anthropological reading of a Roman necropolis based on the archaeological record. The necropolis extends on both sides of the road (second half of the 1st c. AD) and the clusters of tombs are the result of the dynamics of the necropolis system, with a constant striving for visibility by the buyers of family tombs, in some cases incorporating older burials. The function of family tombs is evident from the epigraphs, the arrangements for funeral rites and the rarity of grave goods, which are found rather in the « poorer » tombs, crowded into the spaces between the chamber tombs. The research also shed light on the structuring of a repertoire of funerary ornaments, a theme of great interest for the freedman class buried here. As part of the growing interest in issues related to Roman funerary ideology and by going back over on the history of a project devised many years ago in a highly stimulating university, the paper seeks to show that a context studied as a whole can contribute to discussion in depth of these issues
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
