Interventi per la promozione della salute attraverso le attività motorie nella scuola primaria. Il programma SBAM in Puglia: risultati ed implicazioni pedagogiche e didattiche
No full textL’educazione fisica nella scuola primaria contribuisce in modo significativo al processo educativo del bambino. In molti Paesi dell’UE la sedentarietà è divenuta progressivamente una caratteristica dominante dello stile di vita dei bambini che coinvolge tutte le classi sociali. I livelli di attività fisica destrutturata diminuiscono con l’età e la scuola è il contesto privilegiato per promuovere stili di vita attivi e corrette abitudini alimentari. In Italia l’insegnamento dell’educazione fisica nella scuola primaria è svolto dagli insegnanti generalisti ma, in molte scuole, la proposta di un’offerta didattica di educazione fisica – già da diversi anni – si attua con la presenza di insegnanti specialisti, laureati in scienze motorie e sportive, allo scopo di assicurare efficacia e sistematicità, secondo diverse modalità didattiche ed organizzative. Al fine di promuovere stili di vita attivi e corrette abitudini alimentari a scuola, in Puglia si è svolta la prima edizione del programma regionale triennale inter-istituzionale e multicomponente – SBAM! - che integra tre misure: l’educazione fisica, l’educazione alle corrette abitudini alimentari ed il pedibus. I risultati del monitoraggio hanno evidenziato un’evoluzione delle capacità motorie e dei punteggi inerenti all’auto-efficacia percepita e l’enjoyment, con differenze di genere e di gruppo (secondo le differenze di indice di massa corporea). È in corso di svolgimento la seconda edizione
Promuovere l’attività fisica all’interno del contesto familiare. La dimensione enattiva della relazione educativa
No full textL’epistemologia enattivista, da ritenere oggi quale a quale
frontiera delle scienze cognitive (Stewart, Gapenne & Di Paolo,
2010), è sempre più al centro del dibatito pedagogico e didattico
contemporaneo; secondo tale prospettiva, le strutture mentali
emergerebbero dalle dinamiche senso-motorie che si stabiliscono
tra l’agente “embodied”, vale a dire incarnato, e l’ambiente
“embedded”, dunque, radicato, immerso, integrato (Varela,
Thompson, Rosch, 1991). Tutto ciò ha allora impresso un’ulteriore
centratura educativa sul soggetto, conferendo un ruolo di primo
piano alle relazioni che si stabiliscono tra sè/mondo,
identità/alterità, dunque al processo di apprendimento e, di
conseguenza, a quello di insegnamento (Damiani, 2016). Così,
quella faglia cartesiana che, nel corso dei secoli, aveva presupposto
quella separatezza tra il mentale e il corporeo, il soggettivo e
l’oggettivo, viene notevolmente ridimensionata alla luce del
riconoscimento della mente quale fondamentale componente del
processo conoscitivo (Galimberti, 2008)
Physical activities in Kindergarten: the italian Project a Region in Motion- Play motor Path in the Preschool "Run, Jump & Learn"
No full textBackground. The implementation of a project to promote correct lifestyles of the child is a
pedagogical and educational path that aims to decline different and complementary ways of
promoting health education. Physical activities in the preschool constitute an inescapable range of
experience which is, at the same time, a junction and denominator of further educational
interventions. Various scientific evidences and good practices affirm the preventive role of
structured motor activities regarding numerous pathologies typical of contemporary society and
solicit physical education programs and correct eating habits. A priority for scientific research is
to offer institutions (schools, local administrations) guidelines to develop multi-component
programs, increase the levels of daily physical activity of the child through play, active transport,
the reduction of periods of inactivity, developing the motor skills learning. There is a need to
implement joint actions by the family, school and community, to comply with the Guidelines
concerning the quantity and quality of daily physical activities of children, formulated by the
international scientific bodies. Objectives of the project: a. develop and implement a training
plan, with particular reference to teaching methods, aimed at preschool teachers; b. promote a
motor intervention for all children during the whole school year; c. promote a motor intervention
for all children during the whole school year. In the following contribution, starting from the
relationship between motor development and physical activity, a national project for preschool is
presented: "A Region in Motion - Play-motor path in the preschool" run, jump & learn "aimed at schools
of and that involved in the first edition the regions of Calabria, Basilicata, Marche, Puglia, Sicilia,
Umbria. Methods. Motor experiences, supported by correct methodologies, contribute to selfperception, the learning of different languages and to acquire correct modes of interpersonal and
social relationship. The project has developed educational courses aimed at learning different
languages through physical-motor activities; the teaching methodology was oriented to the
discovery, autonomous and mediated by the teacher, of executive variants of the movement and
to the resolution of problems for the development of creativity
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
Independent value of tumor size and DNA ploidy for the prediction of disease progression in patients with organ-confined renal cell carcinoma
No full textBACKGROUND. Greater than 20% of patients with apparently localized renal cell carcinoma (RCC) present with disease progression after surgery. The objective of the current study was to improve the ability of clinicians to predict prognosis in patients with localized RCC. METHODS, The authors studied 154 patients with organ-confined RCC classified as pT1 to pT2-pN0-M0 who underwent radical nephrectomy. Follow-up ranged from 24-128 months (median, 72 months). Several morphologic parameters of the tumor were considered. DNA content was analyzed by flow cytometry and tumor size was determined from the surgical specimen. A Cox proportional hazards regression model was used to identify significant independent prognostic factors for disease progression. RESULTS. At 5 and 10 years of follow-up, disease free survival was found to be 87% and 86%, respectively. Univariate analysis revealed that DNA content, Furhman grade, and tumor size had a statistically significant predictive value for disease progression, whereas, with regard to grade, the difference was significant only between patients with Grade 3 tumors and all other patients with Grade 1-2 tumors (P < 0.0001). Although DNA content was found to correlate with tumor size (P < 0.0001), multivariate analysis showed that these were the only significant independent predictors of disease progression. The sum of DNA content and tumor size therefore was considered to distinguish separate risk groups. For a patient with diploid RCC, the risk of progression increased from 4% if the tumor size was 3 cm to 43% if the tumor size was 10 cm. For a patient with nondiploid RCC, this risk was 32% if the tumor size was 3 cm, increasing to 99% for tumors measuring 10 cm. CONCLUSIONS, Stratification of organ-confined RCC according to tumor size and DNA content could possibly provide more information that could be useful in the selection of individuals with significantly different risks of disease progression.

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
No full textWe 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
