Calpain system in vitro activity and myofibril fragmentation index in fallow deer (Dama dama): Effects of age and supplementary feeding
No full textCalpain system (μ- and m-calpain, calpastatin) and myofibril fragmentation index (MFI) were analysed on muscle longissimus thoracis et lumborum of 16 male fallow deer, half 18- and half 30-month-old, slaughtered after a 4-month feeding trial on pasture alone or with concentrate supplement. Diet did not produce any difference on the measured variables. The muscle of the elder deer had a higher calpastatin level 6 h post-mortem (136.0 vs. 99.7 units/50 g, for the 30- and 18-months-old, respectively), and a lower MFI value, particularly 24 h post-mortem (71.1 vs. 89.1). This is in agreement with previous data showing tougher meat from 30-month-old animals
Fallow deer milk composition: effect of diet
No full textTwo groups of 6+6 female lactating fallow deer were fed either on pasture alone (PASC) or on pasture plus supplementary feeding (500-700g/head/d; CONC). CONC improved dams’ body condition and suckling fawns’ growth rate. Supplemented deer’s milk was lower in fat and in dry matter, and higher in lactose: it may be argued that CONC milk production was higher. Milk fat, protein and dry matter increased, while lactose decreased in both groups from the 46th to 134th lactation day. Two analytical methods (infra-red spectroscopy and proximate analysis on freeze-dried milk) and two calibration systems within infra-red spectroscopy (buffalo milk and ewe milk) gave similar results for milk fat and protein
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
Effect of milk feeding system on carcass and meat quality of Frisa Valtellinese kid
No full textEffetto del sistema di allattamento sulla qualità della carcassa e della carne del capretto di razza Frisa Valtellinese - Sedici capretti di razza Frisa Valtellinese sono stati allattati naturalmente (N) o
con sostituto del latte (A) e macellati a circa 17 kg di peso. L’alimentazione artificiale ha prodotto un aumento
della resa lorda di macellazione (45,6 vs.. 48,6% per N e A), a causa soprattutto del minor contenuto dell’apparato digerente. Il sistema di allattamento ha avuto una scarsa influenza sulla resa in tagli, mentre la carcassa dei capretti A ha mostrato un maggior rivestimento adiposo (stato d’ingrassamento: 3,5 vs.. 2,2 punti). I principali parametri di qualità della carne (pH finale, colore, perdite alla cottura, resistenza al taglio, analisi tipo)
non sono stati modificati dalla dieta; tuttavia la carne dei capretti allattati naturalmente è risultata più ricca
di C18:3 e C20:5, con un più favorevole rapporto n-3/n-6 (0,77 vs. 0,45)
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
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
