Full text linkIl comparto asinino è una realtà particolare nel contesto zootecnico che presenta problemi del tutto simili a quello equino, ma che ha attualmente delle opportunità di sviluppo probabilmente superiori rispetto agli altri comparti minori zootecnici. La polivalenza dell’asino – come quella del cavallo – che può essere utilizzato per la diversificazione delle attività nelle aziende agricole,come per attività sportive, turistiche, terapeutiche, lo rende infatti un animale fruibile a molteplici livelli, e il suo latte trova ulteriori nuovi sbocchi nell’alimentazione neonatale e per la cosmesi. In questo lavoro si è voluto analizzare i dati del 5° Censimento generale dell’Agricolturadell’Istat, confrontandoli con quelli del Censimento precedente. Alcuni aspetti, sono invece stati sviluppati dai questionari redatti durante le visite svolte dal Dipartimento di Produzione Animali nell’ambito delle attività di ricerca e di tesi negli ultimi due anni presso allevamenti presenti sul territorio regionale. Gli elementi dell’indagine conoscitiva sono stati gli allevamenti asinini e il relativo numero di capi, prendendone in considerazione le variazioni, la distribuzione sul territorio,la superficie aziendale,la forma di conduzione e le dimensioni dell’allevamento

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

No full textSelf-potential have been recently employed as a tool for water fluxes detection in the vadose zone. In this work we present the preliminary results of an on-going research being carried out at the Basilicata University. The aim of the research is to improve the detection of water flux-es in the vadose zone by using a self-potential tomographic technique which gives a 4D (3D + time) high resolution image of water movements within the soil subsurface. Several water in-filtration experiments were performed in both field and lab conditions. In this case, particular-ly, the experiments were performed by using a sand box (6.0 x 4.0 x 2.0 meters) which allow to reproduce a medium-large scale natural environment. SP signals were recorded continuous-ly by using an array of 32 unpolarizable electrodes connected to a multiplexed high imped-ance and resolution multimeter. Better results came out from laboratory experiments where most of the so called cultural noise was reduced at a negligible amount. The results of such experiments have proved that SP tomographic images can represent a good tool for monitor-ing the changes of water fluxes under the boundary conditions which are discussed in the work
