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
I cambiamenti dei comportamenti religiosi ai tempi della pandemia
No full textQuanto sta accadendo in questo periodo pandemico cambia il modo di vivere la fede e il rapporto con la religione? È questa la domanda alla quale si cerca di dare una risposta nel saggio. Si affrontano perciò alcuni aspetti sulle modalità del ‘sentire religioso’, nel periodo del Covid 19, dal 2020 fino ad oggi. In particolare si riconosce il ruolo di Papa Francesco, figura di riferimento nella prima fase della pandemia e il valore simbolico dei suoi gesti per i cattolici, le altre religioni e il mondo. Un altro aspetto riguarda il significato della solitudine del morente di Covid 19, privato della celebrazione di un rito, e del conforto dei suoi cari, incapaci di “elaborare il lutto”. I dati di una ricerca empirica, condotta nel periodo della pandemia, sono significativi per comprendere le dinamiche della religiosità e per ridisegnare il futuro della religione nel post-Covid.If and how it has changed the way in which people live their relationship with religion and faith in this pandemic time? This is the main question of this essay that try to analyse some aspects related to the modalities of ‘religious feeling’, in Covid-19 period, from 2020 to present time. In particular we refer to the significant role of Pope Francis both in the first phase of pandemic and in his relation with Christians beleviers, other religions and the entire world.
Another relevant aspect regard the ‘solitude of the dead’ of Covid-19, that die alone and without celebration, and the ‘consolation of the loved ones’, unable to mourn. The results of an empirical research, conducted during this pandemic, will help us to understand religious dynamic and its redefinitions in post-covid period
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
“Characterization of α-Al2O3 supports modified with CeO2 and ZrO2”
No full textα-Al2O3 is a catalytic support adequate by its high stability, availability, and low cost, although it presents as principal disadvantage its limited surface area and reactivity. These disadvantages in the support lead to catalysts of low metallic dispersion and with weak interaction metal-support. According to characterization results obtained in this work, the addition of small amounts of Ce and Zr oxides to α-Al2O3 leads to CexZr1 − xO2 composites, thus conferring higher reactivity to the surface due to the presence of basic nature sites. This fact together with the well known oxygen storage capacity of these mixed oxides present in composites allow to obtain supports of optimal properties to prevent the sintering and the formation of superficial carbon present in the catalytic deactivation.Fil: Pompeo, Francisco.

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
