A peculiar morphological alteration of canine neutrophils
No full textBackground: Multiple thin nuclear projections in canine blood neutrophils, here named “hairy”, have been anecdotally observed during routine hematology. A similar alteration has been described in people with hypercortisolism.
Objective: To determine the analytical aspects of hairy neutrophils (HN) and their possible association with suspected hypercortisolism.
Methods: Intra-observer repeatability and effects of stains were evaluated on both Hemacolor-stained smears (HSS) and May Grünwald-Giemsa-stained smears (MSS). Inter-observer repeatability was evaluated by two independent operators on HSS. The frequency of HNs and the possible association with suspected hypercortisolism was assessed on 223 HSS from dogs with normal (N=106) or high alkaline phosphatase (ALP) activity (N=117). Cohen’s K, Wilcoxon signed rank, and Spearman tests were performed to respectively evaluate concordance, differences between stains, operators or “ALP groups”, and correlations. Results: HNs were more visible on HSS, that provided higher counts than MSS, although without statistical significance. Intra-observer coefficient of variations ranged from 8 to 10% with higher values at low HN counts. Inter-operator concordance was good (k: 0.73). Results of the operators were significantly different (P=0.015) but correlated (p<0.001, r=0.625). HNs were detected on 74/223 cases (33.2%). The HN count was higher in dogs with high (58.2%) than in dogs with normal ALP (43.4%; P=<0.001) and in dogs with very high (3 X URL) (67.6%) than in dogs with high-normal ALP (48.1%, P=0.007).
Conclusions: HN can be found in dogs, especially in HSS. Finding HN should prompt to measure ALP activity and, if high, to investigate the possible presence of hypercortisolism

I Cancelli del cielo. Economia e politica della grande corsa allo spazio 1950-2050
No full textSe il 2021 ha portato con sé importanti traguardi per l'esplorazione spaziale - con ben tre missioni sponsorizzate da Cina, Stati Uniti ed Emirati Arabi Uniti che hanno raggiunto con successo il pianeta Marte - e i primi voli commerciali costituiti da equipaggi interamente civili hanno dato impulso al turismo spaziale, dal punto di vista strategico sarà lo scontro tra Cina e Stati Uniti a misurare distanze e riavvicinamenti attuali e futuri anche nello spazio extra-atmosferico. Ne parliamo con Raffaele Mauro, autore del volume "I cancelli del cielo: economia e politica della grande corsa allo spazio 1950-2050 (Luiss University Press, 2022)
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
