Use of alternative protein sources for finishing lambs. 2. Effects on chemical and physical characteristics and fatty acid composition of meat.
No full textThis study investigated the use of different protein sources (soybean, faba bean, sweet lupin and pea) in lamb feed and their influence on the chemical and physical characteristics of the meat and on the acid composition of intramuscular fat. The meat of lambs fed on faba bean contained a greater percentage of fat than those fed on lupin (P < 0.05) and soybean (P < 0.01). The meat of lambs fed on faba bean had a greater (P < 0.01) proportion of PUFA and a higher PUFA/SFA ratio than the meat of all other groups. The thrombogenicity index and nutritive value of meat fat were higher for lambs fed with faba bean and pea. The use of lupin in feed determined the highest (P < 0.01) SFA percentage, the lowest PUFA incidence and the worst thrombogenicity index. In conclusion, the protein sources studied did not influence the physical characteristics of the meat. However, the acid composition improved with the use of pea, and especially of faba bean.È stata valutata l’influenza della fonte proteica della razione (soia, favino, lupino e pisello proteico) sulle caratteristiche chimico-fisiche della carne e sul profilo acidico dei lipidi intramuscolari di agnelli in finissaggio. La carne degli agnelli alimentati con favino ha evidenziato una maggiore percentuale di lipidi rispetto a quella dei soggetti riceventi il lupino (P < 0.05) e la soia (P < 0.01) L’alimentazione con il favino, rispetto a tutti gli altri gruppi ha condizionato, una maggiore (P < 0.01) proporzione di PUFA e un maggiore rapporto PUFA/SFA. L’indice di trombogenicità e il valore nutritivo dei lipidi sono risultati migliori negli agnelli riceventi il favino e il pisello proteico. Il lupino ha determinato la maggiore (P < 0.01) percentuale di SFA, la minore incidenza di PUFA e il peggiore indice di trombogenicità. In conclusione, le fonti proteiche allo studio non hanno influenzato le caratteristiche fisiche della carne, mentre, il profilo acidico è stato migliorato dalla presenza, nella razione, del pisello proteico e soprattutto del favino
Dietary supplementation with oregano and linseed in garganica suckling kids: Effects on growth performances and meat quality
Full text linkMeat from Garganica kids fed diets containing oregano and linseed was analysed for physical and sensory properties, chemical and fatty acid composition of intramuscular lipids. Twenty-one three-week-old kids were divided into three homogeneous groups (n = 7), according to age and body weight, and assigned to one of the following feeding treatments: C) control: commercial pelleted feed; L) pelleted feed containing 3% extruded linseed; LO) pelleted feed containing 3% extruded linseed and 0.6% dried oregano inflorescences. Kids were slaughtered at 60 days of age. Diet did not affect in vivo performances, dressing percentage, pH and meat colour, but it influenced meat tenderness, that was lower (P<0.01) in meat from kids receiving oregano, probably due to the lesser (P<0.05) fat content of their meat. The use of oregano also resulted in a lower muscle fat oxidation and in a better meat flavour. As for human health, the dietary supplementation with linseed improved the muscle fatty acid composition, resulting in higher levels of α-linolenic acid (P<0.05) and in a lower n-6/n-3 ratio
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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
