“Intervista a Sofia Borri e Josefina Giglio”
Sofia Borri (Laprida, 1976) ha due anni quando vede per l’ultima volta sua madre, sequestrata dalla polizia militare argentina e mai più tornata. È autrice, insieme a Sara Poma, del podcast Figlie (prodotto da Chora Media per RaiPlay Sound, 2023) in cui si narra la storia della madre di Sofia, Silvia Roncoroni, architetta e militante desaparecida, e della madre di Sara, morta quando lei aveva diciassette anni.
Josefina Giglio (La Plata, 1970) è figlia di Vibel (Virginia Isabel) Cazalas (detenuta scomparsa nel 1977) e Carlos Giglio (detenuto scomparso nel 1976), militanti del Partito Comunista Marxista Leninista (PCML). È autrice del libro Io l’ho amata (Le Commari Edizioni, 2024), traduzione italiana di Yo la quise (Universidad Nacional de La Plata, 2020) in cui narra la storia di sua madre, scomparsa quando lei aveva 7 anni.
Sofia Borri e Josefina Giglio, condividono non solo una relazione di parentela –sono infatti cugine di secondo grado– ma anche la condizione di figlie di desaparecidos. Le autrici, esplorando le fratture e le crepe della storia personale e di quella collettiva, utilizzano l’effimero materiale di cui dispongono –qualche foto, pagine di diario, lettere, testimonianze di conoscenti e amici– per dar voce a chi non ha avuto la possibilità di raccontare, in un cammino dove la ricerca della memoria e della verità si trasforma in un esercizio terapeutico

Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
cateterizzazione non invasiva della vena auricolare per prelievi frequenti nella specie suina
In the modern swine farming often the clinical problems are complex and the diagnosis requires frequent blood samples for several days to assess various biomedical parameters. Several techniques for the collection of swine blood samples are currently in use but most of them involve surgical procedures under general anaesthesia. Several techniques for ear vein catheterization have been developed but they have been tested only for few days. Aim- The aim of this study was to test a non-invasive venous catheterization in swine that allows frequent sampling for several days without any invasive intervention and with minimum disturbance to the animal. Materials and methods - For this study 20 pluriparous sows have been used. The technique involved the implantation of a catheter, with a "through the needle" technique, via the lateral or medial ear vein. The adopted catheters were: Dog Catheter (PVC IV 1.3 × 300 mm-4FG) (n°=10 sows) and Polyetilene Tubing I.D 0.76 mm (0.030" inch) O.D. 1.22 (0.048") 90-120 cm, (n°=10 sows). Frequent blood samplings have been performed every 15 minutes for 6h from 9 a.m. to 3 p.m. for 10 days consecutively or until the catheter was functional. Results - The ear vein catheterization with Polyetilene Tubing has been performed in 16-17 minutes and remained patent for 8-9 days, while the catheterization with the Dog Catheter required 21-23 minutes and remained patent for 4- 5 days. During the trial the pig behaved normally, presented a good appetite and normal body temperature. Conclusion - The permanent ear venous cannulation enables to collect sequential blood samples for several days with minimum restraint of the animal, it does not require surgical procedures under general anaesthesia and it can be applied routinely in the farm
New parametric performance maps for a novel sizing and selection methodology of a Liquid Air Energy Storage system
Liquid Air Energy Storage is one of the most promising novel energy storage concept that guarantees at the same time viable capital cost, high energy density and no geographical/geological constrains. Considering the complexity of the plant, composed by three different phases (charge, discharge and storage), thermodynamic modelling could be a challenging undertaking. Making use of the strong similitude with gas turbine technology, this paper aims to deliver new generalized performance maps for Liquid Air Energy Storage system. The performance maps, validated against the experimental results of Highview Power pilot plant, have been modelled by means of a comprehensive sensitivity analysis carried out considering three macro-scenarios imposing the storage pressures and the turbomachinery performance (design/off-design conditions). By means of the performance maps, the impact of the main LAES operative parameters, as well as the effect of the cold/warm thermal energy storage utilization factor, over the key performance indicators has been assessed and analysed. The analysis shows that at design condition the higher is the value of the high grade cold thermal energy storage utilization factor, the lower is the positive impact of charge pressure over the specific consumption. For off-design condition of the main turbomachinery, the negative effect of lower isentropic efficiency of the main turbomachinery on the round trip efficiency is amplified by the choice of the charge pressure. At high value of the warm energy storage utilization factor, this negative effect can be partially offset by the higher Turbine Inlet Temperature available for the expansion process of the discharge phase
