    Nel saggio si mettono in luce alcuni elementi della biografia di Gabriele Torelli relativi soprattutto al suo "primo periodo napoletano", ovvero alla sua formazione, alla sua prima produzione scientifica e alla movimentata vicenda che lo porterà a vincere la cattedra di Algebra complementare a Palermo. Per analizzare questo periodo si sono utilizzate alcune memorie inedite scritte dallo stesso Torelli. L'ultima parte è dedicata al periodo più intenso della sua attività scientifica, vissuto a Palermo, in cui si concentra su alcuni problemi, ispirati dall'amico Ernesto Cesàro, sulla distribuzione dei numeri primi; questi suoi studi si concreteranno con la pubblicazione della memoria dal titolo: Sulla totalità dei numeri primi fino ad un limite assegnato

    This paper analyzes some critical aspects in view of the strategic role of infrastructures and considering its current deficit in Italy. The first aspect is the difficulty of simplifying complex and interest-ridden procedures, a point on which the Italian legal system’s path is to return to the logic of the “minimum” regulatory frame in the European directives. The second critical aspect is to be found, on the contrary, in the difficulties of raising the necessary resources to promote investments, for which the Administration has turned to PPP s as an instrument to benefit from private capital. Thanks to the Next Generation EU, Italy will have significant European funding, so it is expected that there will be no shortage of resources for the construction of public works. As a result, this study aims to assess whether the private sector will still be able to play an important role in the country’s infrastructure revitalization project.Partiendo del valor estratégico-instrumental de las infraestructuras y dado el actual déficit de las mismas en Italia, el artículo analiza algunos aspectos críticos en este sector. El primero consiste en la dificultad de simplificar procedimientos complejos y plagados de intereses; punto en el que el camino trazado por el ordenamiento jurídico italiano es regresar a la lógica de la regulación “mínima” de las directivas europeas. El segundo aspecto crítico se encuentra, por el contrario, en las dificultades para recabar los recursos necesarios destinados a promover las inversiones, para lo cual la Administración ha acudido a las APP como instrumento para beneficiarse del capital privado. Gracias a la Nueva Generación UE, Italia contará con una importante financiación europea, de manera que se espera que no haya escasez de recursos para la construcción de obras públicas. El presente estudio pretende por ende evaluar si el sector privado aún podrá desempeñar un papel importante en el proyecto de revitalización de la infraestructura del país.Muovendo dal valore strategico-strumentale delle infrastrutture e dato conto dell’attuale deficit infrastrutturale in Italia, l’articolo analizza alcuni aspetti critici del settore. Il primo è quello della difficoltà di semplificare procedimenti complessi e costellati da interessi: sul punto, la via tracciata dall’ordinamento è quella del ritorno alla normativa “minimale” delle direttive europee. La seconda criticità è, invece, rinvenuta nelle difficoltà di reperire le risorse necessarie per promuovere gli investimenti, che hanno spesso consigliato all’amministrazione di definire dei PPP per beneficiare di capitali privati. Considerando che grazie al Next Generation EU l’Italia disporrà di ingenti finanziamenti europei, le risorse per la realizzazione delle opere pubbliche non mancheranno: per questo, lo studio intende valutare se il privato potrà rivestire ancora un ruolo nel progetto di rilancio infrastrutturale del Paese

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 PDF
    We 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 PDF
    We 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

    We 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
