Alcune considerazioni sulla presenza in Italia dei Minori Stranieri Non Accompagnati (MSNA) in relazione alla pandemia Covid-19
No full textAttraverso i dati mensili dei Report statistici sulla presenza dei Minori
Stranieri Non Accompagnati (MSNA), forniti dal Ministero del lavoro e delle
politiche sociali, si analizza il variare del fenomeno dell’insediamento in Italia
degli stessi dal momento di scoppio della pandemia (qui individuato in marzo
2020, momento di inizio del lockdown) rispetto ai circa due anni precedenti (da
gennaio 2018). L’obiettivo è quello di verificare se le difficoltà legate al Covid-19
abbiano, ed eventualmente in che modo, influenzato i flussi e la presenza di MSNA in Italia. Saranno prese in considerazione alcune caratteristiche come il genere, l’età, la nazione di provenienza e la regione di accoglienza di tali minori
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
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
Valutazione dell’efficienza amministrativa del sistema giudiziario tramite Data Envelopment Analysis
No full textUtilizzando un modello DEA (Data Envelopment Analysis) è stato realizzato uno studio sull’efficienza delle corti d’appello italiane. Confrontando il numero dei procedimenti civili e penali, esauriti nel corso di un anno, con le risorse impiegate da ciascuna corte, in termini di magistrati togati presenti e di spese per intercettazioni, si è verificato il livello di efficienza delle diverse strutture territoriali e la loro distanza rispetto alla frontiera produttiva
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
Tourism, a powerful driver for Apulian economy
No full textIn last decades, Tourism has seen a continuous growth, becoming the most important economic sector in the world and one of the key drivers for socio-economic progress of a country. According to the World Tourism Organization, considering its business volume, Tourism is one of the most important segments in international commerce and, at the same time, one of the main income and economic well-being sources for many developing countries, as it produces economic and employment benefits in many related sectors (first of all agriculture, food and accommodation services and cultural heritage). In 2017, Italy confirms to be one of the world’s top international touristic destinations, considering both international arrivals and receipts. This paper aims at understanding the political, social and economic factors that led Tourism to become one of the most influencing sectors on the development of Apulian economy in the last decade. The analysis is carried out by means of time series data on recent international and domestic touristic flows (arrivals, countries of origin, final destination and level of satisfaction) in order to investigate on the key success factors of the “Apulia” brand. After a brief overview of the touristic industry trend, a detailed regional analysis is carried out, considering also cultural events. More in detail, by means of the budget data of all companies active in Apulian tourism sector, the main financial ratios are calculated and then used in a cluster analysis in order to identify similar management patterns. The source of data is the Regional Tourism Board Pugliapromozione and the observational period goes from 2013 to 2017
