Le strategie d’investimento finanziario delle corporazioni napoletane ricostruite attraverso alcuni documenti contabili (sec. XVI-XVIII)
No full textIl contributo, di taglio interdisciplinare, indaga le strategie d’investimento dei capitali raccolti per finanziare
i servizi di assistenza economica agli iscritti, da parte delle corporazioni napoletane tra il XVI e XVIII secolo. La
principale testimonianza dello straordinario giro d’affari di alcune fra le più facoltose corporazioni è custodita in
alcuni fondi d’archivio dei tribunali del Regno, nell’Archivio di Stato di Napoli. Si tratta di stati del patrimonio
immobiliare e di altri documenti che consentono una prima stima delle attività finanziarie. Un caso emblematico è
rappresentato dal ricchissimo ed articolato patrimonio immobiliare della corporazione dei “giudecchieri”
(venditori di vestiti di seconda mano, che possedevano sin dal XIV secolo il monopolio di compravendita degli
abiti prêt-à-porter), frutto di complesse strategie finanziare e indice di una sofisticata capacità di gestione.
The contribution, with an interdisciplinary approach, investigates the investment strategies of the capital raised to
finance the economic assistance services to members, by the Neapolitan guilds between the sixteenth and
eighteenth centuries. The main evidence of the extraordinary turnover of some of the wealthiest guilds is kept in
some archive funds of the courts of the Kingdom, in the Naples State Archives. These are the statuses of the real
estate assets and other documents that make it possible an initial estimate of financial assets. An emblematic case
is represented by the very rich and articulated real estate assets of the guild of the “giudecchieri” (sellers of
second-hand clothes, who had the monopoly of buying and selling prêt-à-porter clothes since the 14th century),
result of complex financial strategies and index of sophisticated wealth management skills

Stability analysis of pyroclastic covers by a new geoelectrical-hydrogeological approach
No full textWe propose an original approach that combines ERT, resistivity laboratory measurements and seepage analysis to analyze the stability conditions of Peri-Vesuvian area (Campania region, southern Italy) characterized by ash-fall deposits resulting from the volcanic activity of the Mt. Somma-Vesuvius, which overlap a carbonate basement. Geological, structural and hydrogeological conditions of this area may often trigger very rapid landslides as debris slides and debris flows. Due to the high resistivity contrast between pyroclastic soils and carbonate basement, geoelectrical measurements are a very useful tool for landslide investigations.
We use the results of a high-resolution 2D resistivity survey to obtain a stratigraphical model of a test slope area. A steady-state representative of the in-situ conditions is achieved by comparing the synthetic water content distribution resulting from seepage analysis with that resulting from resistivity measurements. Such a comparison is made by means of characteristic curves resistivity vs. water content obtained by accurate geoelectrical characterization of pyroclastic samples collected in the same survey area. Starting from the achieved steady-state, we simulate the rainfalls preceding the occurrence of the catastrophic landslide of May 1998. The applied conditions provide the 2D water content distribution within the pyroclastic cover on the day when the landslide occurred. Finally, by using the characteristic curves electrical resistivity vs. water content, we convert water content variations in resistivity variations critical for the considered landslide event
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
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
l1-Regularization in Portfolio Selection with Machine Learning
No full textIn this work, we investigate the application of Deep Learning in Portfolio selection in a Markowitz mean-variance framework. We refer to a l1 regularized multi-period model; the choice of the l1 norm aims at producing sparse solutions. A crucial issue is the choice of the regularization parameter, which must realize a trade-off between fidelity to data and regularization. We propose an algorithm based on neural networks for the automatic selection of the regularization parameter. Once the neural network training is completed, an estimate of the regularization parameter can be computed via forward propagation. Numerical experiments and comparisons performed on real data validate the approach
