Sacrocaudal (sacrococcygeal) intervertebral disc protrusion in 2 cats
No full textOne cat was presented for investigation of urinary retention and constipation and a second cat was presented with decreased appetite, reluctance to jump, reduced level of activity, and constipation. Magnetic resonance imaging revealed dorsal bulging of the hypo-intense intervertebral disc at S3-Cdl on fast spin echo T2. Dorsal laminectomy was performed and both cats recovered with resolution of neurological signs
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
Immunohistochemical and lectin histochemical analysis of the Alpaca efferent ducts
No full textAn immunohistochemical and lectin histochemical study of the efferent ducts was performed in the alpaca. Two types of epithelium were detected on the basis of the different cytokeratins expression and lectin binding pattern. AE1/AE3 and 13 cytokeratin antibodies intensely immunostained the entire cytoplasm of type I PCs, whereas AE1/AE3, but not anti cytokeratin 13, immunoreacted in type II principal cells along the apical, lateral and basal plasma-membrane. The histochemical characterization of the epithelial cells was carried out using different lectins: Con-A, UEA-I, LTA, WGA, GSA-II, GSA-IB4, SBA, PNA, ECA, DBA, MAL-II and SNA. Sialidase digestion and deglycosilation pre-treatments were also employed. In type I principal cells, the staining of the Golgi zone was interpreted giving evidence for the synthesis and secretion of O- and N-linked oligosaccharides. In II principal cells, the lectin staining was observed in the apical cytoplasmic granules and in vacuoles that were interpreted as components of an elaborate endocytotic apparatus specialized for the uptake of particulate material and fluid from the lumen. These results suggest the existence of two structurally different epithelial segments along the ductuli efferentes of the alpaca, with a high degree of compartmentalization of the secretory and absorptive activities
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
La morte violenta del soggetto di provenienza extracomunitaria nel settorato dell'Istituto di Medicina Legale di Parma nel periodo 1984-2003: revisione casistica.
No full textGli Autori analizzano la casistica autoptica dell'Istituto di Medicina Legale di Parma nel periodo 1984-2003 relativamente alla fattispecie della morte violenta nella popolazione extracomunitaria del territorio di pertinenza. Sono stati analizzati i dati relativi a provenienza, età, sesso e modalità del decesso, anche per quanto riguarda il rapporto con l'andamento del fenomeno omicidiario e di quello suicidiario nella popolazione generali, al fine di individuare, nell'ambito del fenomeno migratorio, utili indicatori statistici
The sustainable “4 F” for rainbow trout (Oncorhynchus mykiss) feeding: Feedstuffs from the Fish Farmer Farmhouse
No full textIn trout production, feed sustainability, together animal welfare, quality of the final product and environmental impact are the main challenges to face for the operators. For the aim, a trial was carried out comparing two different feeds characterized by different dietary ingredient composition: D1 included fish meal and conventional feedstuffs and D2 with co-products deriving from fish processing as main protein and lipid source and vegetable feedstuffs coming from the farmhouse owned by the same fish farmer. 600 young rainbow trout (Oncorhynchus mykiss, mean body weight=48±3g) were reared in 6 tanks resulting in 3 replicates per dietary treatment. The main physico-chemical water parameters were monitored to evaluate effects on the environment. At the end of the 8-week trial, the most important growth performances and quality of the fillet were determined in terms of proximate composition and fatty acid profile. Both the groups reached a suitable final mean body weight (D1=172±35.7g; D2=151.65±34.7g). The feed conversion showed a better rate in D2 (1.03±0.02) compared to D1 (1.3±0.03). Water quality exhibited an improvement of the main chemical parameters with a reduction of total ammonia nitrogen and nitrites in D2 (TAN=0.23 mg/l; NO2-N=0.08 mg/l). No significant differences were observed in fish fillet quality and fatty acid profile. This study showed that dietary ingredient composition, as co-products deriving from animal processing, together with vegetable feedstuffs from the farmer farmhouse, favourably affected the sustainability of the trout production system
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 textDispelling 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
