Detection of canine parvovirus in wolves from Italy
No full textOne hundred fifteen samples of wolf (Canis lupus) feces were collected during 1994 to 1995 from four free-living populations of the north central Apennines Mountains, Italy. The samples were tested for canine parvovirus by antigen-capture enzyme-linked immunosorbent assay (ELISA), hemagglutination, and virus isolation. Four of these samples were positive by virus isolation as confirmed by electron microscopy. All positive samples were from Casentino Park in Tuscany. This is the first definitive observation of canine parvovirus in wolves from Europe
Divergence of central nervous system involvement in 2 Italian sisters with congenital muscular dystrophy: A clinical and neuroradiological follow-up
No full textWe report the clinical and neuroradiological follow-up of 2 Italian sisters, 10 and 6 years of age, affected by congenital muscular dystrophy (CMD) with divergent CNS involvement. In both, CMD was diagnosed by finding dystrophic alterations in muscle biopsy and muscular deficit at birth. The elder sister suffered also from marked intellectual deficit and epilepsy, as usually reported in children with Fukuyama CMD. In the same patient, at 2 years of age, CT scan showed severe hypodensity of cerebral white matter and severe ventricular dilatation of occipital horns. At 8 years of age, MRI also showed clearcut pachygyria mainly in the parietal and occipital lobes. MRI and CT scan at the same age showed improvement of the leukoencephalopathy and unchanged ventricular dilatation, as reported for patients with Fukuyama CMD. Unlike Japanese cases, however, she showed no progression in her muscular deficit and her muscle immunostaining of laminin M chain (merosin) was normal. The younger sister had normal mental development, never experienced epileptic fits and had always normal EEG. However, as often seen in classical CMD, her CT scan showed moderate hypomyelination of cerebral white matter and mild dilatation of lateral ventricles. MRI did not show any other brain abnormalities. Sequential CT scan at 2, 4 and 6 years of age showed improvement of the leukoencephalopathy. Her muscular deficit had a stationary clinical course. Her immunostaining of muscle merosin was moderately reduced. The finding of Fukuyama-like and classical CMD in 2 sisters indicates the possibility that different forms of CMD may be different expressions of the same genetic disease
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
Echinococcosis/hydatidosis in Emilia-Romagna: a study of hospital admissions in the period of 1989-1993
No full textAn overview of the epidemiology human echinococcosis/hydatidosis is presented for the Emilia-Romagna region during the period 1989-1993. Data were extracted from hospital discharge reports. The description was based on 806 discharges totaling 10187 days of stay. Thirty-five percent of the patients discharged were residents outside the Emilia-Romagna region. A significant statistical correlation was identified between a high average yearly incidence of the disease and a relatively small jurisdiction of residency. No correlation was established between average yearly incidence and number and density of sheep and goats and farms and estimated dogs
Dispelling the Myths Behind First-author Citation Counts
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
