Poeti dialettali salentini: Erminio Giulio Caputo e Francesco Morelli
Full text linkI poeti salentini Erminio Giulio Caputo e Francesco Morelli rappresentano due voci significative nel panorama della letteratura dialettale meridionale. Negli ultimi decenni del Novecento, il primo da premesse ironico-satiriche e di costume giunge a un vorticoso slancio mistico, di autentica vena lirico-religiosa, su fondamenti agostiniani. Morelli invece assurge a cantore dell'epos di una nazione contadina a metà Novecento, su premesse carducciane innervate da una sensibilità lirica di ascendenza pascoliana
Premessa a [Il volto oscuro della prevenzione patrimoniale. Studio sui profili critici della confisca]
No full textIl contributo presenta il volume oggetto di curatela, esponendo la chiave critica che gli autori hanno adottato nell'esame di taluni profili della confisca preventiva. Il nucleo del metodo adottato è rappresentato dall'analisi della prevenzione patrimoniale con la lente dei diritti costituzionali e di quelli sanciti dalla CED
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
A DESIGN PROPOSAL FOR DISSIPATIVE SEISMIC-RESISTANT AUTOMATED RACK SUPPORTED WAREHOUSES
No full textIn logistic field, Automated Rack Supported Warehouses (ARSWs) are buildings for the storage of goods which adopts the steel racks as both stoking areas and primary structural system. Re-cent collapses and damages after seismic events highlighted the criticalities of the current de-sign, which is based on the regulations for traditional racks (i.e. EN16681) or for ordinary buildings (as Euro-codes) that are not fully appropriate, given the peculiarities of ARSWs. In this paper, possible so-lutions to design dissipative and seismic-resistant ARSWs are investigated. Starting from the tech-nical solutions currently adopted and from regulations for dissipative buildings, global optimization is performed with the aim of selecting the most appropriate structural type allowing to fulfill all the requirements (i.e. the hierarchy rules). Then, local optimization is carried out for the dissipative elements, with the aim of obtaining an over-resistant connection with respect to the element. Indeed, the fulfillment of this request is challenging for the profiles adopted in ARSWs, which are thin walled, implying a limited bearing capacity of the connection. As a solution to this issue, the cross section of the profiles is locally reduced to limit tensile resistance, but this also weaken the element, affecting the behaviour in compression and due to cyclic loading. Numerical optimization is per-formed for the optimization of the layout of the reduced parts, aiming to find the right balance among tensile resistance, ductility demand and good performance in compression
EXPERIMENTAL BEHAVIOR OF DISSIPATIVE THIN-WALLED BRACINGS
No full textThis paper presents the dissipative capacities of thin-walled reduced-section elements evaluated through an experimental campaign. The reduction of the cross section is introduced to fulfill of hierarchy rules for dissipative structures when these elements are used as diagonals in Automated Rack Supported Warehouses. Indeed, cold-formed thin-walled elements are adopted in these struc-tures, and for these elements the limited bearing capacity of their connections to the other elements does not allow the dissipation of seismic energy through yielding and plastic deformation of diag-onals. The reduction of the cross section is so necessary, allowing to obtain a resistance of the diagonal lower than the bearing capacity. Anyway, it introduces issues related to the local stability of the reduced part. The behavior of this type of elements is firstly numerically predicted, selecting four possible different layouts for the reduced parts. Then, the actual behavior is validated through the execution of an extensive experimental campaign where tensile and compression monotonic tests are per-formed, as well as cyclic ones. The results of the experimental campaign are used for the calibration of the numerical models and the final evaluation of the performance of whole case-study structures where these dissipative elements may be implemented
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
