Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Studi e progetti sugli spazi aperti della Certosa di Pisa a Calci
No full textLa memoria fornisce un quadro di sintesi sullo stato delle conoscenze
delle aree a verde della Certosa di Pisa a Calci, sintetizzando i numerosi
studi che, negli ultimi decenni, hanno approfondito la documentazione
di spazi verdi o singoli elementi dell’architettura costruita e
di quella vegetale. Il contributo si sofferma, in modo particolare, sugli
spazi aperti esterni al recinto claustrale, meno conosciuti rispetto a
quelli del nucleo interno, e caratterizzati da coltivazioni agricole e
spazi per la riflessione. Sono infine riportate prime considerazioni su
un progetto per il restauro paesaggistico e per la valorizzazione della
fruizione di queste porzioni della Certosa.The report provides a summary of the state of knowledge about the
gardens of the Pisa Charterhouse, also known as Calci Charterhouse,
summarizing the many studies and researches that have deepened
the documentation of green spaces or individual elements of building
and natural architecture in the last decades. In particular, the contribution
focuses on the open spaces outside the cloistered enclosure,
less known than those of the internal core, and characterized by agricultural
crops and spaces for contemplation. The project describes
first reflections for landscape restoration and for the enhancement of
the use of these sections of the Charterhouse
Contesti territoriali di pregio paesaggistico e operatività delle aziende agricole in un’area della Toscana. Un’analisi esplorativa per le policy
No full textIl contributo riporta i risultati di un’indagine condotta nelle Colline Lucchesi (LU): un
contesto paesaggistico di pregio della Toscana dove si è voluto verificare come e in che
modo le norme del PIT-PPR stanno incidendo sull’operatività delle imprese agricole. Si
ricorda, infatti, che durante l’iter di approvazione del Piano Paesaggistico della Toscana,
avvenuto nel 2014, nacque un intenso dibattito con gli operatori agricoli che ritenevano
alcune indicazioni per le azioni dei morfotipi rurali un vincolo alla loro libertà di impresa. A
distanza di qualche anno, la ricerca ha voluto verificare l’effettiva sussistenza di tali vincoli
cercando di capire se e a quale livello le aziende agricole sostengono dei costi (diretti e
indiretti) per il mantenimento del paesaggio e l’eventuale presenza di “svantaggi
competitivi” rispetto ad aziende operanti al di fuori di tali contesti. La metodologia di
indagine si è basata sull’utilizzazione di mappe aziendali per facilitare l’interazione con
l’intervistato nel far emergere gli aspetti più rilevanti nella gestione degli elementi del
paesaggio e per esplorare anche la sua percezione / idea rispetto ai valori paesaggistici del
morfotipo rurale nel quale ricade la propria azienda
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country

Mining e-mail content for author identification forensics
No full textWe describe an investigation into e-mail content mining for author identification, or authorship attribution, for the purpose of forensic investigation. We focus our discussion on the ability to discriminate between authors for the case of both aggregated e-mail topics as well as across different email topics. An extended set of e-mail document features including structural characteristics and linguistic patterns were derived and, together with a Support Vector Machine learning algorithm, were used for mining the e-mail content. Experiments using a number of e-mail documents generated by different authors on a set of topics gave promising results for both aggregated and multi-topic author categorisation
