Una popolazione relitta di Pelobates fuscus insubricus in un sito litoraneo veneto (Amphibia: Pelobatidae)
No full textA previously unknown population of Spadefoot Toad (Pelobates fuscus (LAURENTI, 1768))
has been discovered in 2005 at a coastal site near Rosolina, between the Venice Lagoon and the Po
Delta. It is the only relic population of the species currently known in the Veneto region, as well as
among the few populations in the North-Adriatic coastal plain

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
How to Measure 24-hour Central Blood Pressure and Its Potential Clinical Implications
No full textThe evaluation of 24-hour central blood pressure (24h cBP) combines the cBP non-invasive assessment with the 24-h ambulatory BP measurement. The major strength of the 24-h cBP evaluation is the ability to assess the degree of circadian changes between central and peripheral BP, namely 24-h BP amplification. This allows an accurate quantification of the degree of spatial and temporal BP variability in each single individual. BP amplification depends from a number of factors, such as the interaction between pressure and flow pulsatile motions, vasomotor tone, arterial tapering and other physiological and anthropometrical determinants. The assessment of 24-h BP amplification, a relatively pressure-independent parameter, may be helpful in better refining the risk of organ damage and future CV events over traditional measures of office and 24-h brachial BP. Currently, only few devices enable the assessment of 24-h cBP. These devices are based on peripheral (brachial or radial) BP waveform detection, and reconstruction of central BP waveform through mathematical models. The estimation of 24-h cBP imputed from multivariate regression equations was also proposed. Clinical data are still scarce and, although suggesting a possible superiority of 24-h cBP over brachial BP in the association with markers of organ damage, they are limited by methodological and technical aspects. There is urgent need of a standardized methodology and rigorous validation protocols for the 24-h cBP assessment. The field of 24-h cBP measurement still requires significant advancements of scientific knowledge before its introduction into clinical practice

No full textSearching for specific motifs in affinity capture in proteome analysis
No full textIn analysing the red blood cell cytoplasmic proteome, in search for low abundance proteins, 15 amino acid (AA; Arg, Asn, Asp, Gln, Gly, His, Ile, Lys, Phe, Pro, Ser, Thr, Trp, Tyr, and Val) probes, used individually, captured a total of 787 unique gene products. Of those, 76 were found to be the common catch of all AA probes, 497 were captured by more than one (but not all) probe, and 214 were captured by only one probe. By using the InterPro database, for 151 of the 214 IPIs associated with proteins captured by a single amino acid, we have found 265 annotations of motifs (231 protein domains, 3 binding sites, 3 active sites, 13 conserved sites, and 15 repeats). Among these 151 proteins annotated, there are 75 domains, 2 active sites, 5 conserved sites, and 3 repeats (a total of 85 motifs) that are at all effects amino acid strictly specific. As a result of these findings, these 85 amino acid specific motifs singled out 40 (18.69%) of the total list of 214 proteins representing the total capture of the 15 AAs here reported. If one considers that only for 151 (70.56%) of the 214 proteins data about interacting motifs could be collected, the percentage of proteins for which the 85 amino acid strictly specific motifs have been found increases to the even more relevant value of 26.49%. The identified motifs can partially explain the exclusive protein capture of the 15 amino acid probes. The unique general and specific capturing ability of two of these AA probes, Phe and Arg, is evaluated, discussed and put in perspective
