Electronic identification of sheep in Sardinia: a retrospective analysis of the past fifteen years
Full text linkThis doctorate thesis provides a general background and new research findings on the electronic identification of ruminants. The first chapter is a literature review on electronic devices used for livestock identification. The other chapters describe experimental work on electronic identification devices, mostly in dairy sheep but also in goats. Chapter 2 deals with the effect of the presence and permanence time (from few days to 9 years) of four types of ceramic boluses (differing in capsule size, weight and material) used for electronic identification of Sarda sheep in six farms on the reticulum and chemical-physical characteristics of the interface surface. The boluses showed the presence of calcium, manganese, and zinc salts. The long-term permanence of the bolus in situ caused little changes in the mucosa which did not seem to impair the organ function. Chapter 3 comparing traditional and electronic animal identification in dairy sheep farms showed that the electronic identification device was more realiable, effective and efficient than the ear tag and ear tattoo. Chapter 4 studied possible correlations between the presence of rumen bolus and calcium content in blood, during pregnancy and lactation, and in milk in early, mid and late lactation in Sarda sheep. Calcium content in blood and milk did not differ between ewes with or without ceramic bolus. Chapter 5 concerns animal reading and data collection efficiency of automated milk recording in dairy sheep and goats

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
