Il progetto di catalogazione TESS Lombardia : dati acquisiti e prospettive di ricerca
No full textThe digitalization of floor mosaics from western and eastern Lombardy – carried out in the TESS Project – has collected 1088 published occurrences. The most popular paving techniques are the mortar floor (447) and tessellatum (369), but also the opus sectile (81), with stone slab (87), brick (63) and cobblestone floors (14) are attested. Occasionally, the discovery of mosaic floors is only mentioned, quoting the site of the area of an urban centre, without providing any information on the technical and decorative aspects. Also this kind of information – vague and rather pointless for advancing any typological and iconographical consideration – evidences the presence of ancient structures in an area. The most widespread decoration is the geometric style, both in black and white, but also with a sober polychromy. Figural decorations are scarce and clustered in eastern and south-eastern Lombardy, but are attested also in the west. The modern borders of Lombardy do not reflect the Roman and Late Antique territorial organisation, when the area included part of Regio X, Venetia et Istria and XI, Transpadana: This factor must be taken in consideration during the analysis of technique and decoration – in term of patterns and organisation of the decorated space – in mosaics from the region. This paper aims at providing a synthetic analysis of the whole data collected, starting from the paving technique and decoration and considering the relationship between floor, paved space and architectural context, applying a chronological and topographic approach, shading light on aspects like the decorative repertoire, colour and design
Cryptic diversification in ancient asexuals: evidence from the bdelloid rotifer Philodina flaviceps
No full textBdelloid rotifers, darwinulid ostracods and some oribatid mites have been called 'ancient asexuals' as they speciated and survived over long-term evolutionary timescale without sexual recombination. Data on their genetic diversification are contrasting: within-species diversification is present mostly at a continental scale in a parthenogenetic oribatid mite, whereas almost no genetic diversification at all seems to occur within darwinulid ostracod species. Strangely enough, no clear data for bdelloid rotifers are available so far. In this paper, we analyse partial COI mtDNA sequences to show that a bdelloid rotifer, Philodina flaviceps, so far considered a single traditional morphological species, has actually been able to diversify into at least nine distinct evolutionary entities, with genetic distances between lineages comparable with those between different traditional species within the same genus. We discovered that local coexistence of such different independent lineages is very common: up to four lineages were found in a same stream, and up to three in a single moss sample of 5 cm2. In contrast to the large-scale geographic pattern that has recently been reported in the oribatid mite, the spatial distribution of the bdelloid lineages provided evidence of micro-phylogeographic patterns. If the mtDNA diversity indicates that the lineages are independent and represent sympatric cryptic species within P. flaviceps, then the actual bdelloid diversity can be expected to be much greater than that recognized today
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
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

No full textHemostatic variables as risk factors for carotid intima-media thickness progression in patients with pheripheral arterial disease
No full textBackground: Changes in common carotid intima-media thickness
(CC-IMT), as measured by B-mode ultrasonography, have been used
in both population studies and clinical trials to seek risk factors for
early atherosclerosis progression and have already been associated
with age, high low density lipoprotein cholesterol, leukocytes,
hemoglobin, and fibrinogen.
Objective: To assess the relations between baseline hemostatic and
Conventional risk factors and CC-IMT changes over 16 months
(delta CC-IMT) in 64 peripheral arterial disease (PAD) patients randomly
selected from the prospective PLAT study (1).
Design: Samples from 24 (37.5%) patients who presented an
increase of CC-IMT during the follow-up period were compared with
those from 40 (62.5%) in whom CC-IMT remained unchanged during
the same time frame.
Results: Conventional risk factors and coagulation variables were
similar in the two groups except for higher vWF:Ag (178.3±53.6 vs
141.2±53.7%, p=0.01) and FVII (133.9±36.4 vs 107.0±27.3%,
p=0.001) in the patients with increased CC-IMT. Delta CC-IMT correlated
positively with plasma levels of FVII (r=0.31, p<0.01) and vWF
(r=0.31, p<0.01). Multiple stepwise regression analysis identified FVII
as the only independent variable associated with positive changes
of CC-IMT (r=0.83, r2=10.6, p=0.01).
Conclusions: High FVII and vWF:Ag might be risk factors for the
progression of early carotid atherosclerosis in PAD patients.
