Origine e caratteristiche dei terreni
No full textI terreni sono costituiti da particelle minerali che, insieme
all'aria e/o all'acqua, presenti negli interstizi fra queste, formano
un sistema multifase. Una vasta parte della superficie
terrestre è caratterizzata dall'affioramento di terreni che sono
ampiamente utilizzati come materiali da costruzione o, interessati
da opere di ingegneria civile e mineraria, alla cui crescente

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
Il Diritto dell’Amministrazione Pubblica digitale
No full textL’innovazione materiale e culturale che l’informatica ha imposto alle scien-ze giuridiche e alle Pubbliche Amministrazioni ha ormai più di sessant’anni; ciò è avvenuto tra successi innegabili, molte resistenze e reali difficoltà, se-guendo percorsi tutt’affatto lineari, come esattamente ricorda Mario G. Losa-no nell’introduzione al volume.
Raccogliere e interpretare le innumerevoli disposizioni che disciplinano l’amministrazione pubblica digitale, per quanto passaggio necessario, non intendeva ridursi ad un’attività di mera compilazione, finalizzata a sé stessa. L’obiettivo dei curatori di questo volume è ben più ambizioso: si tratta di tentare di mettere in evidenza e sottolineare come, in sé, l’innovazione tecnologica sia di sistema e come sia dunque proprio da tale esperienza e cultura pregressa che essa trae oggi la forza che le è essenziale per andare oltre.The material and cultural innovation that information technology has imposed on legal sciences and public administrations is now over sixty years old; this took place amidst undeniable successes, many resistances and real difficulties, following paths that are by no means linear, as Mario G. Losano remembers exactly in the introduction to the volume.
Collecting and interpreting the countless provisions governing digital public administration, although necessary, was not intended to be reduced to a mere compilation activity, aimed at itself. The objective of the editors of this volume is much more ambitious: it is a question of trying to highlight and underline how, in itself, technological innovation is systemic and how it is therefore precisely from this past experience and culture that it draws today the strength that is essential to it to go further
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
Alcune considerazioni sulle misure inclinometriche
No full textL'esame di circa un migliaio di misure
inclinometriche ha permesso di individuare
alcuni «fattori di disturbo»
che si manifestano con le caratteristiche
di veri e propri movimenti del terreno,
sovrapponendosi talvolta a questi, esaltandoli
o minimizzandoli, e, comunque,
rendendo difficile o errata l'interpretazione
delle misure.
Tali «fattori di disturbo» sembrano
da attribuire, per la massima parte dei
casi, alle modalità costruttive del foro
inclinometrico, per cui, nel presente
studio, dopo aver descritto ed analizzato
questi «fattori», individuandone le cause
di origine, si suggeriscono alcune
modalità esecutive da seguire nella realizzazione
dei fori, per eliminare o, comunque,
minimizzare il falsamento delle
misure
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
