Does the use of ensiled forage affect the sensory properties of fresh cheese?
No full textThe present work aimed to evaluate the effects of the forage preservation method (silage vs. hay) on the chemical and sensory characteristics of two artisanal, fresh cheeses: ricotta and ‘primo sale’. A 6-ha dryland field (760 m above sea level) was sown with a legume-grass mixture (Lolium multiflorum, Triticum aestivum cv.Ludwig, Trifolium alexandrinum, Trifolium squarrosum spp.) at a 40–60 ratio. At harvest (early flowering of legumes), half of the forage (3 ha) was chopped at a theoretical length of 1.1 cm and ensiled in plastic film, whereas the other half was air-dried to hay and then stored in 1.2-m-diameter round bales. Three months after the forage harvesting, thirty-two lactating Holstein cows were randomly allocated into 2 groups, silage (S) and hay (H), balanced for DIM (141 ± 76 vs. 141 ± 69 d, respectively, for the S and H group), milk yield (29.6 ± 10.0 vs. 29.0 ± 8.9 kg/ head per d), and milk quality (fat 3.8 ± 0.74 vs. 3.7 ± 0.78%; protein 3.2 ± 0.4 vs. 3.2 ± 0.4%). Group H was fed a TMR containing as the sole forage the experimental hay which for group S was replaced by the experimental silage. A limited amount of the experimental hay (5.0 kg as fed) was included in the silage based TMR to provide a basic level of physically effective fiber. After 10 d of adaptation to the diets, during 3 consecutive morning milk¬ing, bulk milk of each group was separately collected to manu¬facture ‘primo sale’ and ricotta cheeses. Milk and cheeses from each batch of production were collected to be analyzed for macro components, fatty acids (FA) profile, and sensory properties (Quantitative Descriptive Analysis). Data were analyzed with a one-way ANOVA to assess the effects of diet (S and H). The chem¬ical and FA compositions of ricotta and ‘primo sale’ were not affected by the preservation method. Regarding the sensory prop¬erties, the ‘primo sale’ cheese produced on the silage diet was more acidic and saltier (p < 0.05) than that produced on the hay diet. Similarly, S-ricotta was saltier (p < 0.001), but it also scored lower in brightness (p < 0.001) and color intensity (p < 0.05). The consumer panel did not perceive any differences between ricotta and primo sale produced on S and H diets. The results indicate that although experienced panelists may detect little difference, the forage preservation has no effect on consumers’ liking of fresh cheese

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
