Comportamento delle lepri allevate in harem e in coppia fissa.
No full textHare behaviour was video recorded during two years. The hares were reared in cage in fixed couples and in harem. The presence in display zone, rest, feeding, drinking, locomotion, reproduction, comfort and stereotypes were observed. Results showed that presence in display zone decreased February through June; rest and comfort behaviour were observed during the whole season. repeated activities (stereotypes) were observed in couples bred hares during the whole season while in harem bred hares were observed mainly during the starting of the reproductive season

No full textHare behaviour was video recorded during two years. In the first yearr the hares were video recorded during the whole day; in the second year the hares were video recorded February thriugh March, April through May, and June through July, from 8:00 AM to 10:30 AM, and from 4:00 PM to 6:30 PM (peaks of activity observed during daylight) Presence in display zone of the cages, rest, feeding, drinking, locomotion, reproduction, comfort and stereotypes were video recorded. Results showed that: presence in display zone decreased February through June. Repeated activities (stereotypes) were observed, in couple bred hares during the whole season while in harem bred hares mainly during the starting of the reproductive season. Aggressivness was mainly related to refuse of mating in couple-bred hares, and to feeding competitivity in harem.bred hares
L’impiego della paglia di avena come alimento complementare nella lepre
No full textThe aim of this study was to evaluate the digestibility in the hare of two commercial feeds with or without oat straw fed ad libitum. Four couples bred hares were fed ad libitum with two commercial pellet (first pellet: crude protein 17% and crude fibre 21%; second pellet: crude protein 15% and crude fibre 23%) with or without oat straw. Feed intake was not significantly influenced by the addition of oat straw, although the hares decreased the pellet intake in presence of oat straw. The coefficients of digestibility were higher in 15% p - 23% f .pellet than in 17% p - 21% f. pellet. The oat straw did not decrease the digestibility of the organic matter, probably in relationship to a best production and utilization of soft faeces
Comportamento e performance del gallo forcello (Tetrao tetrix L.) allevato a fini sperimentali nel parco dell'Orecchiella (Toscana)
No full textCptive breeding of black grouse is justified because this species id declining in most of the alpine areas, at the edge of its distribution area. Only reared black grouse originating from the alpine population, can be used for re-introducing the species in the alpine areas where it has disappeared or is endangered. The experimental breeding started in natural park and was based on fixed pairs. Since it was not possible to use artificial feed, some natural long-fibre supplementary feed with siliceous grit is alwyas given. The laying period in the experimental breeding farm was monitored. Eggs were artificially incubated. Chick were reared in commercial heated cages for the first 4 weeks before transferred to the pens The behaviour of the caged black grouses showed the typical seasonal course of the specie and no stereotypies were observed

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
