A CRITICAL APPROACH OF THE CALCULATION PROCEDURES TO BE USED IN DIGESTIBILITY DETERMINATION OF FEED INGREDIENTS FOR RABBITS
No full text[EN] The effect of differences between tested ingredient and
basal diet dry matter content and the effect of premix inclusion on the
digestible nutrient content of tested feedstuffs are analysed. The
calculation procedures to be followed in digestibility evaluation assays of
feed ingredients far rabbits are also described by means of examples.
The impact of dry matter correction on the estimation of the digestible
nutrient content of tested ingredient increases with increasing of
differences between the dry matter content of basal diet and tested ingredient, and between the nutrient content of basal and test diet, and
with decreasing substitution rate, varying from 0.05% to 9%. Premix
correction increases the digestible nutrient content of tested ingredient
proportionally to the premix addition (calculated on dry matter basis) and
independently of the substitution rate and of the kind of feedstuff
evaluated. Nevertheless, the complete correction (both by dry matter
and premix) sometimes has a compensatory effect, when corrections
act in opposite way.[FR] Les auteurs ont analysé les conséquences des différences de
composition entre la matiere premiere testée et le régime de base
servant a l'étudier, ainsi que les effets de la prise en compte du taux
d'inclusion du prémix, dans l'estimation de la digestibilité des éléments
nutritifs de cette matiere premiere. La procédure de calcul qu'il convient
de suivre pour la mesure de la digestibilité d'une matiere premiere est
décrite a l'aide d'exemoles. L'effet de la correction pour la teneur en
matiere séche de la mutiere premiere étudiée est d'autant plus grand
que cette teneur s'éloigne de celle de l'aliment de base, ou que s'accroit
l'écart de teneurs en nutriments digestibles entre l'aliment de base et
l'aliment expérimental contenant la matiere premiere étudiée. L'effet de la correction pour la teneur en matiére seche s'accroit aussi avec la
réduction du taux d'incorporation de la matiere premiére étudiée. Selon
les situations, cette correction pour la teneur en matiere séche, a un
impact qui représente de 0,05% a 9% des teneurs en éléments
digestibles estimées. La correction liée a la prise en compte du prémix
(lorsqu'il est incorporé a taux fixe dans taus les régimes expérimentaux)
accroit la valeur de la digestibilité attribuée aux nutriments de la matiere
premiere étudiée, de maniere proportionnelle au taux d'incorporation de
ce prémix (calculé sur la base de la matiere seche), quel que soit le type
de matiere premiere ou le taux de substitution entre le régime de base
et la matiere premiere étudiée.. Toutefois, la correction complete
(matiere seche et prémix ensemble) a quelquefois un effet
compensateur, quand les corrections agissent de maniere opposée ..Villamide, M.; Maertens, L.; Cervera, C.; Perez, J.; Xiccato, G. (2001).

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
Rafael Cervera (c. 1563-1633). Aproximación a la trayectoria social desde el discurso de un erudito de la primera Edad Moderna
No full textDue to the importance of his writings and his erudition, Rafael Cervera (c. 1563-1633) was one of the greatest Catalan intellectuals of the seventeenth century, becoming one of the authors of reference for the history of Barcelona and Catalonia for many later authors. In this article I will analyse the author's life trajectory and the speeches he made in his works with the aim of exploring his political and cultural contacts in order to provide an example of the social trajectory and thought of an author from Barcelona in the early Modern Age, while also answering a number of other questions that arise from this reading of the author.Por la importancia de sus escritos y su erudición, Rafael Cervera (c. 1563-1633) fue uno de los mayores intelectuales catalanes del siglo XVII, situándose como uno de los autores de referencia para la historia de Barcelona y Cataluña para muchos autores posteriores. En este artículo voy a analizar la trayectoria vital del autor y los discursos que emitió en sus obras con el fin de indagar en sus contactos políticos y culturales a fin de aportar un ejemplo de trayectoria social y de pensamiento de un autor de la Barcelona de la primera Edad Moderna, respondiendo también a otras diversas cuestiones que surgen de esta lectura del autor
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
