Social play and affiliation as possible coping strategies in a group of Maremmana beef cattle
No full textAnimal internal states can be expressed via social behaviors that are known to shape group dynamics (i.e., allogrooming, social play, agonistic encounters) and that can be flexibly used after experiencing negative stimuli. In extensively bred domestic species, animals are not always used to human handling, and thus also mandatory health checks can alter group dynamics. Here, we investigated possible fluctuations in social behaviors according to the presence and distance from the health check in a group of young Maremmana heifers and steers in semi-extensive conditions. We found that aggression did not change in relation to the health check. On the contrary, the time individuals spent playing and affiliating with each other drastically reduced in the day after the routinary check (Post 1, 0-24 h) if compared to days far from the event (Control): after that, it reached the highest level in the following day (Post 2, 24-48 h). This rebound effect might allow animals to compensate for the previous lack of social interactions and to restore social homeostasis. The findings suggest that social interactions in Maremmana cattle are informative about their internal states. Additionally, social play and allogrooming appear to function as coping strategies for these cattle
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

No full textVariations 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

Effetto del pascolo erbaceo sulle caratteristiche dei prodotti freschi e stagionati di suini di razza Cinta Senese
No full textLa caratterizzare dei prodotti freschi e stagionati di Cinta Senese risulta quanto mai indispensabile a causa dell’eterogenea tecnica di allevamento e alimentazione utilizzata. L’obiettivo di questa tesi è stato quello di valutare le performance produttive di suini di razza Cinta Senese alimentati durante la fase di finissaggio con pascolo erbaceo per periodi di diversa durata. 6 suini maschi castrati e 10 femmine del peso vivo di circa 100-120 kg sono stati divisi in due gruppi di 8 soggetti ciascuno e sottoposti ad un diverso regime alimentare: il gruppo “C” (CONCENTRATO) ha ricevuto un’alimentazione a base di soli cereali, mentre il gruppo “P” (PASCOLO) ha usufruito di pascolo erbaceo con un’integrazione di mangime dello stesso tipo del gruppo “C”. I soggetti sono stati sottoposti a controlli ponderali cadenzati; successivamente sono state effettuate macellazioni scalari in modo da produrre soggetti che avessero ricevuto un’alimentazione a base di pascolo per un periodo variabile (durata stimata a 50, 100, 150 d), così da valutare la dinamica del cambiamento della composizione della carcassa e delle caratteristiche chimico-organolettiche del prodotto finito. Le analisi fisiche e chimiche sono state effettuate sui muscoli Longissimus Lumborum e Psoas major e sulla componente adiposa. È stata inoltre effettuata l’analisi chimica e quella sensoriale del lardo stagionato da parte di una commissione di Panel Test esperta. I risultati hanno indicato come l’introduzione della componente erbacea nella dieta non sembri influenzare il peso della carcassa e le sue diverse componenti, conferendo invece alle carni ottime caratteristiche in termini di tenerezza e sapidità (grasso intermuscolare). Ciò può deporre a favore della possibilità di gestire la fase di finissaggio sostituendo il 50% della dieta con il pascolo: l’utilizzo del pascolo erbaceo nella fase di finissaggio potrebbe anche permettere, così, di inserire l’allevamento della razza Cinta Senese, generalmente condotto in modo semi-brado o brado, in una vera e propria rotazione agronomica dei terreni a disposizione dell’allevatore. Da un punto di vista qualitativo sono state rilevate differenze riguardanti una maggiore presenza della componente n-3 negli animali al pascolo, senza però fornire presupposti per possibili alterazioni tecnologiche dei prodotti stagionati. Anche in questo caso, tuttavia, non sono emerse particolari differenze che possano indicare l’influenza del tempo di pascolamento sulla qualità dei prodotti freschi e del lardo stagionato
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
