THREATENED FISH OF THE WORLD: LEUCISCUS LUCUMONIS BIANCO, 1982.
No full textThis Italian endemic species has undergone a progressive
decline in its original range since it was
first described. Leucisus lucumonis is an important biogeographic
indicator of the Tuscany-Latium district. At present there are only about 10–12 isolated populations. According
to the 2002 IUCN Red List of Threatened Species. www.redlist.org,
downloaded on 14 August 2002, the status of this species (erroneously
reported as L. lucumontis, Bianco 1983) was listed as at ‘Lower Risk’,
(conservation dependent). Today L. lucumonis can be allocated to the endangered category for threatened species as it satisfies paragraph B and
point 1 of the IUCN (1996) criterion ‘Severely fragmented distribution’
Non solo Roma. Torino, i Savoia e le Fiandre nei Campeggiamenti di Emanuele Tesauro (1639)
No full textNon solo Roma. Torino, i Savoia e le Fiandre nei Campeggiamenti di Emanuele Tesauro (1639) This essay focuses on the siege of Saint-Omer, an episode of the Thirty Years War, as seen through the eyes of several contemporaries. The first part, written by Blythe Alice Raviola, is dedicated to Emanuele Tesauro’s Sant’Omero assediato (1639). Tesauro followed prince Thomas of Savoy as court historiographer during his Flemish campaign; therefore this book should be read within the political and diplomatic context of the Savoy court. Sant’Omero assediato is considered not only as an account of the military operations, but also as a plaidoyer for Thomas’ political and military activity. The second part of the article, by Luca Bianco, establishes several connections with art historical aspects of the siege and of Tesauro’s mission. Bianco examines the subsequent frontispieces of his book and Tesauro’s possible knowledge of Karel Van Mander’s Le livre des Peintres. The final part of the article sheds light on two little-known visual representations of the siege: an artfully drawn map by Pieter Snayers and an etching by Stefano Della Bella. Whereas the first is probably produced for military purposes, Bianco proposes Tuscan Ottavio Piccolomini, Thomas’ fellow condottiero and a noteworthy collector, as the hypothetic commissioner of Della Bella’s etching, which could be considered as a visual counterpart to Tesauro’s literary account
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
Sarmarutilus Bianco & Ketmaier, 2014, n. gen.
No full text<i>Sarmarutilus</i> n. gen. <p> Type species: <i>Leuciscus rubilio Bonaparte,</i> 1837: Fauna It: fasc. XIX, Tav III (Type locality; voulcanic lakes of Nemi and Bracciano, central Italy).</p> <p> <b>Diagnosis.</b> The species, previously classified as <i>Rutilus rubilio</i>, cannot be placed in the genus <i>Rutilus,</i> because of the pharyngeal teeth formulae, 5- 5 in <i>R. rubilio</i> and 6-6 or 6- 5 in <i>Rutilus</i>, of the small size and the riverine preference as opposed to still waters and large size in <i>Rutilus</i>. Similarly, it cannot be placed in the genus <i>Leucos</i> for the presence of prominent tubercles at the center of each scale of the body and on the head in reproductive males (Fig. 4), a character unknown in the genus <i>Leucos</i>, and for the preferentially riverine habits as opposed to still waters in the five species of <i>Leucos</i>. In addition, it shows a marked lateral stripe, quite different from that of <i>L. aula</i>, masked by heavy pigmentation on flanks formed by well marked crescent triangular spot on scales (Fig. 2 F), of a shape not found in any of all other species of <i>Leucos</i> and <i>Rutilus</i> in the examined area. Finally, it is well separated from the <i>Leucos</i> species on karyology grounds (Bianco <i>et al</i>., 2004) and from <i>Rutilus</i> and <i>Leucos</i> at the mtDNA level (Ketmaier <i>at al.</i>, 2008).</p> <p> <b>Etymology</b>. The generic name derives from the Sarmatic Sea, or Lago Mare, an ancient central European inner freshwater sea where this monotypic genus probably has its evolutionary roots.</p> <p> <b>Origins.</b> Sequence variation of the entire mitochondrial cytochrome b gene shows a strict relationship among five species, which diverged from a Leuciscinae ancestor about 4–5 million years ago, during the Lago Mare phase of the Mediterranean Sea (Bianco, 1990). Similar biogeographic and temporal patterns have been observed in the genus <i>Telestes</i>, which occupies the same geographic area (Ketmaier <i>et al.</i>, 2004). According to karyology (Bianco <i>et al.</i>, 2004) <i>Sarmarutilus rubilio</i> displays few, if any, elements with centromeric heterochromatin and many with solid telomeric bands; this evidence differentiates <i>S. rubilio</i> from two representative species of the genus <i>Leucos</i> (<i>L. aula</i> and <i>L. panosi</i>). The three examined species should be considered as of distinct origins and, according to molecular data, probably separated since the Lago Mare Phase of the Mediterranean Sea in the Miocene Messinian (5 MYA).</p>Published as part of <i>Bianco, Pier Giorgio & Ketmaier, Valerio, 2014, A revision of the Rutilus complex from Mediterranean Europe with description of a new genus, Sarmarutilus, and a new species, Rutilus stoumboudae (Teleostei: Cyprinidae), pp. 379-402 in Zootaxa 3841 (3)</i> on page 392, DOI: 10.11646/zootaxa.3841.3.4, <a href="http://zenodo.org/record/225778">http://zenodo.org/record/225778</a>

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
The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
The development of growth rings on ancient glass surfaces: Description and simulation of the weathering
No full textThe present work investigates the weathering process of glass surfaces with the formation of corrosion growth rings investigated by
X-ray photoelectron spectroscopy, optical microscope, environmental scanning electron microscope and particle induced X-ray emission.
The analysed samples are both ancient and recent glasses. The first set of samples is constituted by Roman glass fragments originally
belonging to the load of the Iulia Felix ship, sunken in the Northern Adriatic sea (Grado, Italy) during II century AD. The samples
were already investigated in the past [F. Barbana, R. Bertoncello, L. Milanese, C. Sada, J. Non-Cryst. Solids 337 (2) (2004) 136; B. Dal
Bianco, R. Bertoncello, L. Milanese, S. Barison, J. Non-Cryst. Solids 343 (2004) 91; B. Dal Bianco, R. Bertoncello, L. Milanese, S. Barison,
Surface Eng. 21 (5–6) (2005) 393; B. Dal Bianco, R. Bertoncello, L. Milanese, S. Barison, Archaeometry 47 (2) (2005) 353], but their
production process is still unknown. The second set of samples belongs to the stained window of S. Giovanni church in Polegge (Vicenza,
Italy) and it is dated to 1930 ca. The glass production process is well known. In fact, every tessera is made of soda-lime glass. On one side
only, the glass is coated with a green pigment (low melting temperature glass) and then heated in oven in order to fix it on the glass. The
window is then mounted and fixed to the wall. Unfortunately, during this procedure, the window was positioned inside-out, so that the
painted surface was exposed to the direct action of the atmospheric conditions. This anomaly favoured the fast degradation of the tessera,
with the presence of concentric rings at the surface. Another set of samples was produced in order to simulate the effects of moisture
at the glass surface, using an industrial soda-lime glass and coating it with a painting originally used in 1930s. The comparisons between
the corrosion of the three sets of samples suggest that the Iulia Felix glasses could have been prepared with the same technique.
