No full textCatalogo della mostra realizzata presso la Biblioteca Ariostea di Ferrara, in occasione del 250° anniversario della nascita di Vincenzo Monti (2004). Monti fu studente illustre dell'Università di Ferrara. Il catalogo è introdotto da brevi saggi di G. Barbarisi, L. Pepe, W. Moretti, D.Tongiorgi, T. Matarrese, G. Nalini Montanari
Regolo circolare per aumento ponderale desiderabile in gravidanza
No full textConsiderate le implicazioni per feto e madre, che un inappropriato aumento ponderale potrebbe comportare, e constatate le difficoltà percepite nel tentativo di monitorare tale parametro, si avverte urgente la necessità di poter usufruire di uno strumento di facile ed immediato utilizzo, tarato su validi valori di riferimento , per poter individuare il peso ideale per la paziente in gravidanza.
Nasce così il regolo di controllo che consente di individuare l’aumento di peso auspicabile per la gravida, prendendo in considerazione sia il valore di BMI pregravidico sia l’età gestazionale, in modo tale da assicurare la possibilità di monitorare l’incremento ponderale della paziente secondo un criterio personalizzato.
Lo strumento, tascabile, consta di due facce (A e B) (figure 1,2,3). Consultando A è possibile ricavare il valore di BMI pregravidico (kg/m2), indicato nell’ apposita finestra, dopo aver allineato peso (kg) e altezza (m) della paziente. Passando a B, in base al valore di BMI precedentemente ricavato, la paziente rientrerà in una delle categorie di peso contrassegnate da diversi colori: sottopeso (BMI<18.5 kg/m2), normopeso (18.5-24.9 kg/m2), sovrappeso (25-29.9 kg/m2), obesità (BMI≥30 kg/m2). Collocando la finestra sulla settimana di gestazione, essa indicherà anche l’incremento ponderale minimo e massimo per ogni categoria di BMI.
Il regolo è stato costruito sfruttando come valori di riferimento le raccomandazioni della SINU, sezione “il fabbisogno energetico in gravidanza”, con l’intento di fornire al personale medico ed ostetrico uno strumento di rapida ed agevole consultazione con cui valutare quasi “a colpo d’occhio” il trend ponderale della gestante, potendo, così, intervenire prontamente là dove esso abbia assunto un andamento indesiderato.
A tale scopo, si è pensato di scegliere uno strumento dalla forma già familiare e nota agli operatori di ostetricia e ginecologia, per permettere una veloce e semplice, seppur molto utile, valutazione del più elementare indice dello stato di nutrizione: il peso corporeo.
Indubbiamente, valutazioni impedenzometriche, in grado di individuare variazioni delle percentuali di massa magra e massa grassa nonché il livello di ritenzione idrica, consentirebbero di delineare un profilo ancor più specifico e dettagliato. Tuttavia, il semplice monitoraggio ponderale, con l’ausilio del regolo, costituirebbe un primo significativo traguardo, nell’ottica di assicurare alla gestante un routinario controllo del trend ponderale
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
Assessment of weight gain during pregnancy: an Italian practical approach
No full textWeight increase during pregnancy is an extremely useful parameter since adequate weight gain is associated with better outcomes for the health of both the mother and the baby. On the other hand, if there is an inappropriate change in weight, either too much or too little, both mother and foetus are more greatly exposed to numerous complications with different degrees of seriousness. Therefore it is necessary to rely on appropriate guidelines that provide medical and obstetric personnel with clear directions regarding correct weight gain. Since the recommendations of the guidelines must be adapted to the patient’s specific profile, establishing the ideal weight gain in numerical terms is not immediate.
Therefore we developed an instrument for estimating the ideal weight gain during pregnancy, which is quick and easy to use and takes the specific subject's characteristics into account, in order to allow a personalized evaluation.
A pocket instrument was developed, with a circular shape and two sides (A and B). On side A, two concentric disks contain weight and height, which allow pre-pregnancy BMI (Body Mass Index) to be calculated. On side B, three concentric disks contain respectively: a solar calendar, a calendar calculating the week of pregnancy and a window behind which the desired weight gain values scroll, divided by weight category.
We believe that the instrument may be an additional helpful tool to control weight gain during pregnancy
