Utilizzo degli e-book per familiarizzare i bambini alle verdure.
Introduzione. Il primo approccio dei bambini al cibo solido, e in particolare alle verdure, non è sempre semplice per i genitori L’effetto di diverse strategie di familiarizzazione è stato studiato da numerose ricerche, che hanno messo in luce una varietà di metodi: ripetizione per più giorni della proposta di verdura non gradita; utilizzo di ricompense materiali – come ad esempio una figurina con i personaggi preferiti – e non-materiali, come la lode e l’incoraggiamento; informazioni ai genitori sull’alimentazione sana, etc.
Un metodo recentemente proposto in Inghilterra e che ha dimostrato una buona efficacia nel familiarizzare i bambini a una verdura nuova o non gradita, è quello della lettura condivisa fra bambini e genitori di un libro illustrato che presenti la verdura in questione, dalla coltivazione nel campo al piatto cucinato.
La nostra ricerca, condotta all’interno del progetto See&Eat finanziato dalla Comunità Europea si propone di verificare l’efficacia della lettura di e-book sull’approccio alla verdura, quindi l’efficacia di una esposizione ripetuta in forma virtuale nell’aumentare la disponibilità ad assaggiare, il consumo e il gradimento di una nuova verdura.
Metodo. La ricerca ha coinvolto 61 famiglie con bambini di età compresa fra 18 mesi e 4 anni: a ognuna è stato chiesto di indicare due verdure non gradite al bambino (su un elenco di 24), ed è stato chiesto di leggere per 15 giorni un e-book su una delle due verdure, scelta in modo casuale. Prima e dopo il periodo di lettura, i genitori hanno compilato un questionario che valutava la disponibilità ad assaggiare, il consumo e il gradimento di entrambe le verdure: la verdura target (quella oggetto dell’e-book), e quella non-target, altrettanto sgradita ma non oggetto di intervento.
Risultati. I questionari hanno mostrato un incremento significativo su tutte e tre le voci al post-test, sia per la verdura target che per quella non-target.
Discussione. Anche se non abbiamo trovato differenze significative fra le due condizioni, possiamo interpretare l’effetto di generalizzazione sul gradimento e sul consumo delle verdure come un risultato importante, dovuto alla maggiore attenzione comunque prestata nell’ambiente familiare alla verdura, risultato che del resto trova conferma in altre ricerche analoghe ed è stato confermato dai commenti espressi da alcuni dei genitori partecipanti in un focus-group di verifica dell’iniziativa
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
Psychosexual Education Interventions for Autistic Youth and Adults—A Systematic Review
(1) Background: The literature shows a general lack of sexual knowledge and appropriate sexual health education in persons with Autism Spectrum Disorders (ASD). Moreover, the existing interventions mainly target the neurotypical population, without addressing the specific needs of individuals with ASD. (2) Aims: The current systematic review aimed at analyzing the literature encompassing psycho-educational interventions on sexuality addressed exclusively to people with ASD, in order to report the good practices and to describe the effectiveness of the existing programs. (3) Methods: The systematic review followed the PRISMA-P method. The literature search was conducted in June 2022, examining PsycInfo, PsycArticle, PubMed, and Education Source. The search strategy generated 550 articles, of which 22 duplicates were removed, 510 papers were excluded for not matching the criteria, and 18 articles were finally included. (4) Results: Ten papers presented good practices and eight focused on intervention validation. The analysis showed that the good practices were essentially applied in the intervention studies. No intervention proved to be successful both in increasing psychosexual knowledge and in promoting appropriate sexual behaviors; thus, further research is needed. (5) Conclusions: The current review allows for critical reflection on the need for validated sexuality interventions
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
Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Home-based interventions targeting vegetable intake and liking among preschoolers: A systematic review
Consumption of vegetables is low among preschoolers and does not meet WHO recommendations. We conducted a systematic review of home-based interventions aimed at increasing vegetable consumption and liking among preschoolers. The main aim was to synthesize existing studies and to identify relevant features of successful interventions, especially looking at those with long-lasting effects. A comprehensive search strategy was performed using Psychinfo, PsychArticles, Psyndex, Medline and ERIC databases. Articles published until February 2020, regarding evaluation of vegetable intake and/ or liking following an intervention, were included. Fourteen articles were selected, encompassing seven intervention strategies: familiarization with vegetable, tasting of the vegetable, intake of the vegetable, reward, information to parents about healthy eating, how-to-do tips to parents to improve healthy eating, intervention tailored to the characteristics of the family. Successful interventions on vegetable intake did not present systematic similarities in terms of type of intervention, but were characterized by an intense intervention (high frequency/length ratio). Successful interventions on vegetable liking mainly included a small reward. Interestingly, the few studies including a long-term follow-up found persistent positive effects. Despite interesting and promising outcomes, the present review highlighted a number of methodological issues that limited the generalisability of findings. Such limitations are discussed, together with outlets for future directions concerning this research topic
