Brexit: before and after. A corpus-assisted study of the Referendum campaigns and the immediate aftermath
No full textIn this work, we look at how attitudes to the 2016 Brexit Referendum were represented in a number of UK national newspapers, some of which were broadly pro-Brexit, others anti-Brexit, in the three-month period immediately before the vote and in a similar stretch of time after. Given the large scale of data, the examination availed itself of corpus linguistics and corpus-assisted discourse studies (CADS) methodologies. The principal impression arising from the data before the vote was that to divide attitudes towards Brexit into “for or “against” was far too simplistic. They were many shades of opinion between the two extremes. In addition, both the “for” and the “against” sides contained leftwing and rightwing voices. As regards the comments of various agents after the vote, we uncovered some rather surprising reactions by both the “winners” and “losers”
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
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
Sustainability in the livestock sector. Possible mitigation systems of environmental impact of breeding
No full textLa sfida più grande per il settore agro-zootecnico è ridurre i compromessi tra incremento della produttività e sostenibilità a lungo termine. In ragione della crescente domanda alimentare stimolata dall’aumento della popolazione mondiale e dalla globalizzazione, il settore zootecnico dovrà far fronte ad una richiesta alimentare senza precedenti che richiederà, oltre all’aumento di prodotti alimentari di origine animale, di intensificare lo sfruttamento delle risorse naturali, generando un aumento dell’impatto ambientale del settore.
L’attenzione mondiale è rivolta ormai da molti anni agli effetti negativi generati nei confronti dell’ambiente dalle attività antropiche e sono stati di conseguenza sviluppati piani mondiali per riuscire a risolvere, o per lo meno migliorare, i danni ambientali che stanno scatenando una catena di eventi degenerativi terrestri. Tutti i settori partecipano alla produzione di emissioni e generano impatto ambientale, compreso il settore zootecnico che, grazie alla sua espansione mondiale e alla differenziazione del settore, ha un impatto ambientale significativo.
I settori zootecnico svolgono anche molteplici ruoli positivi che rientrano in tutti gli Obiettivi di Sviluppo Sostenibile (OSS) dell’Agenda globale 2030, con interazioni e anche compromessi molteplici e diversificati. Lo sviluppo di nuove tecniche e tecnologie per migliorare il settore zootecnico, sia dal punto di vista ambientale ma anche del benessere animale e sostegno alle comunità, rientra negli obiettivi di sviluppo sostenibile e può aiutare a migliorare molti aspetti della sostenibilità in quanto i suoi obiettivi sono intimamente interconnessi e migliorandone alcuni questi possono influenzare anche tutti gli altri.The biggest challenge for the agro-zootechnical sector is to reduce the
trade-offs between increased productivity and long-term sustainability.
Due to the growing food demand stimulated by the global population and
globalization, the livestock sector will have to cope with an unprecedented food
demand that will require, in addition to the increase in food products of animal
origin, to intensify the exploitation of natural resources, generating an increase in
the environmental impact of the sector.
The worldwide attention is now turned for many years to the negative
effects generated towards the environment by anthropic activites and have been
developed as a result world plans to be able to solve, and, or at least improve, the
environmental damage that is triggering a chain of degenerative terrestrial events.
All sectors partecipate in the production of emissions and generate environmental
impact, including the livestock sector which, thanks to its worldwide expansion and
differentation of the sector, has a significant environmental impact.
Livestock sectors also play multiple positive roles that fall under all
Sustainable Development Goals (SDGs) of the Global Agenda 2030, with multiple
and diverse interacRons and also trade-offs. The development of new techniques
and technologies to improve the livestock sector, both from an environmental point
of view but also from an animal welfare and community support point of view, it is
part of the sustainable development goals and can help to improve many aspect
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
