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
CORTE COSTITUZIONALE E GIUSTIZIABILITÀ DELL’EQUILIBRIO DI BILANCIO
No full textI vari precetti costituzionali che fanno capo alla revisione del 2012 differiscono tra di loro (non solo per contenuto, ma anche, coerentemente) per il grado di giustiziabilità dinanzi al giudice delle leggi. Per quanto riguarda, in particolare, l’equilibrio in senso stretto del bilancio statale (o dei conti complessivi del comparto pubblico), ragioni sostanziali e procedurali concorrono ad assegnare alla Corte costituzionale un ruolo non in prima linea; concentrato su un controllo esterno delle valutazioni economiche e delle ragioni addotte per esse; limitato anche quanto agli effetti di eventuali pronunce di accoglimento
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
Study of the beam-cavity interaction in the PS 10 MHz RF system
Full text linkThe eleven main accelerating cavities of the Proton Synchrotron (PS) at CERN consist of two ferrite-loaded coaxial lambda/4 resonators each. Both resonators oscillate in phase, as their gaps are electrically connected by short bars. They are in addition magnetically coupled via the bias loop used for cavity tuning. The cavities are equipped with a wide-band feedback system, limiting the beam loading, and a further reduction of the beam induced voltage is achieved by relays
which short-circuit each half-resonator gap when the cavity is not in use. Asymmetries of the beam induced voltage observed in the two half-cavities indicate that the coupling between the two resonators is not as tight as expected. The total cavity impedance coupling to the beam may be affected differently by the contributions of both resonators. A dedicated measurement campaign with high-intensity proton beam and numerical simulation have been performed to investigate the beam-cavity interaction. This paper reports the result of the study and the work aiming at the development of a model of the system, including the wide-band feedback, which reproduces this interaction
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
C'è un giudice a Lussemburgo? Sui limiti strutturali e sostanziali alla tutela giurisdizionale dei singoli rispetto alle politiche di austerity dell'Unione europea
No full textÈ noto che il locus standi dei singoli innanzi alla Corte di giustizia è sottoposto a condizioni stringenti dal diritto primario (solo tangenzialmente modificate dalla riforma di Lisbona), rispetto alle quali la giurisprudenza sovranazionale – nonostante le aperture mostrate in pronunce di primo grado e da alcuni Avvocati generali – ha sin qui adottato un approccio di particolare rigore. Quanto appena detto acquista poi ancor più rilievo con riferimento alla tutela apprestata rispetto alle politiche di austerity adottate per fare fronte alla crisi economico-finanziaria che ha colpito i Paesi UE a partire dal 2008. In questo caso, peraltro, non si pone solo, una questione di accesso alla giustizia, determinata tanto dal limitato locus standi di cui i singoli beneficiano quanto dalla natura delle misure controverse e dal loro legame con l’ordinamento UE. Ad emergere è pure il tema relativo all’ampiezza della cognizione esercitabile dai giudici di Lussemburgo su tali misure, di norma concepite come strumenti adottati per il perseguimento di un interesse generale asseritamente superiore (in ultimo riconducibile alla sopravvivenza della zona euro) e spesso caratterizzate da una forte connotazione di matrice tecnica. Il presente lavoro intende analizzare questi due profili, contribuendo in tal modo a ricostruire i limiti – strutturali e sostanziali – all’accesso alla giustizia sovranazionale in subiecta materia
