I giovani, la formazione e le opportunità. Prospettive di diritto comparato sull'orizzonte della sostenibilità
No full textIl saggio si propone di analizzare l’importanza della formazione nel promuovere la ripresa dopo la crisi innescata dal Covid-19. In particolare, in un contesto europeo che muove verso l’innovazione e la sostenibilità diviene particolarmente rilevante anche la formazione del giurista comparatista, la quale può consentirgli di trovare soluzioni e strumenti innovativi che si pongono in consonanza con le prospettive della sostenibilità, come nel caso delle Società Benefit
Modelli teorici e radici culturali. una riflessione sugli esiti emergenziali tra occidente ed oriente
No full textQuanto ogni Sistema è fedele al “sentiero”? Quanto le emergenze incidono su di esso? Lo scritto cerca di indagare il rapporto tra il retroterra culturale e giuridico, da un lato, e la reazione all’emergenza, dall’altro. Si tenta in esso di ricostruire, prima, i connotati essenziali dell’esperienza giuridica cinese così come di quella occidentale e, segnatamente, statunitense per poi osservarne il tipo di risposta alla diffusione del virus globale. Lo scopo è cercare di comprendere quanto la crisi pandemica (ma anche le crisi in generale) possano mettere alla prova i Sistemi e la loro coerenza rispetto alla c.d. path dependency. Può l’emergenza innescare una deviazione rispetto alle proprie radici culturali o può consolidarle? Può così sollecitare “movimenti” dei Sistemi avvicinandoli o può rafforzarne i connotati storici dimostrandone la coerenza? Dinanzi a tali tematiche/problematiche l’analisi comparatistica s’impone per una riflessione prospettica
[Atheroembolic syndrome due to isolated infrarenal abdominal aorta stenosis and endovascular treatment: case report and review of literature]
No full textOne of the most common source of lower extremity atheroembolization is the aorta and particularly the infrarenal segment. Complex atherosclerotic plaque can lead the patient to gangrene and major amputation. When the origin of embolization is a focal lesion, endoluminal methods could be an alternative to surgical treatment. Although the experience with aortic stent is limited, the results obtained so far seem to be encouraging. The case of a mid-age heavy smoker woman with a history of the abrupt onset of painfull cyanotic toes in the left foot and subsequent complete gangrene of the first digit in the same foot is herein reported. Angiography and CT scan revealed an high-grade calcified aortic infrarenal plaque. Because of the discrete characteristic of the lesion, an endovascular approach with a Palmaz stent was elected. The stenosis was successfully treated: the patient experienced the complete resolution of the toe painfull cyanosis within 3 months, the stent remained patent through a 24 months follow-up and no subsequent embolic episodes were observed
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
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
