Realizzazione e gestione di siti di nidificazione per i pronubi selvatici del Parco Monte Barro: il Progetto BarroBugBox
No full textIl Progetto BarroBugBox è stato avviato nel 2013 con l’intento di salvaguardare e promuovere le comunità di pronubi selvatici presenti nel Parco Regionale del Monte Barro e nell’omonimo Parco Naturale, rispettivamente SIC e ZPS, in Provincia di Lecco. Sono state quindi realizzate e posizionate, in zone ritenute idonee all’interno del Parco, due tipologie di strutture artificiali, denominate BugBox e BugTube, atte a fornire siti idonei alla nidificazione dei pronubi selvatici. Le BugBox sono costituite da strutture lignee recanti vani contenenti differenti tipologie di materiale (legni forati, canne di bambù, cannucce di palude, strobili e mattoni forati), mentre le BugTube sono realizzate con sezioni di tubo in polipropilene contenenti unicamente cannucce di palude. L’installazione è stata seguita da controlli periodici necessari sia per il monitoraggio delle eventuali colonizzazioni che per la manutenzione delle strutture. Nel corso del progetto sono state inoltre sviluppate e applicate buone pratiche necessarie per una gestione efficiente delle strutture, ad esempio in caso di forti infestazioni da parte di Imenotteri Formicidi. Già dopo alcuni mesi dal posizionamento, tra gli Artropodi rinvenuti si sono riscontrate nidificazioni di pronubi selvatici quali Imenotteri Apoidei Megachilidi del genere Osmia, nonché di altri Apoidei impollinatori, tutti in aumento negli ultimi controlli. Al terzo anno dall’avvio del progetto si nota una buona efficienza di colonizzazione delle strutture, anche grazie alle soluzioni adottate per la gestione delle stesse. Data la possibilità di realizzazione senza eccessivo impegno di costi, materiali e personale, i progetti per la tutela degli impollinatori selvatici mediante l’impiego di BugBox e BugTube meritano di essere considerati in diversi ambienti, sia naturali che sub-urbani o urbani
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
New insights on Troglophilus (Orthoptera Rhaphidophoridae) species distribution in the westernmost area of their main range (Northern Italy)
No full textThe genus TroglophilusKrauss includes species with a rather limited dispersal ability and a wide distribution range, making it a good model for biogeographic, phylogeographic and phylogenetic investigations, with growing interest in recent years. However, a crucial prerequisite for addressing biogeographic issues is the knowledge about species complete distribution range. In particu-lar, Troglophilus cavicola(Kollar) and Troglophilus neglectusKrauss are the species of the genus Troglophiluswith the widest distribution in Europe, where their main areal extends westward to Northern Italy, but their precise distribution and range limits are still uncertain. In this study, the presence of these two species, which overwinter in hypogean habitats, was investigated in caves of the westernmost area of Northern Italy (Lombardy, Provinces of Lecco and Como) where populations belonging to the genus Troglophiluswere reported. The individuals of these populations were described by previous literature as T. cavicolaor as Troglophilussp. without species determination. In this work, an in situ morphological identification of all individuals detected in the surveyed caves, and a molecular identification on 12 specimens through the COI barcoding, were performed. An effective, fast, simple, economical and easily reproducible protocol for DNA extraction was optimized for this taxon. The presence ofT. cavicolain the investigated area was confirmed and the presence of T. neglectuswas reported for the first time. These new data allowed us to hypothesize different scenarios about their dispersal route in Lombardy. Moreover, these new findings must be con-sidered to define sampling plans to elucidate the biogeography of this genus
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

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
