Il gruppo interuniversitario “Condizione adulta e processi formativi”: interessi di ricerca e linee progettuali
No full textSu iniziativa di Duccio Demetrio, si è istituito, a febbraio 2010, un gruppo di ricerca interuniversitario animato dalla volontà di confronto e di collaborazione sui temi e problemi dell’educazione degli adulti. I frequenti contatti tra i partecipanti hanno progressivamente delineato e consolidato la sua composizione e la sua operatività, consentendo di individuare una mission di fondo, articolata in filoni tematici e in approcci metodologici principalmente tesi a fare emergere sia le criticità del settore sia le prospettive di un suo rilancio, tanto sul versante degli orientamenti teorici quanto su quello delle pratiche. L’attività del gruppo ha già dato luogo ad iniziative di disseminazione culturale come la realizzazione di monografie e saggi collettanei, la fondazione di due collane editoriali, l’organizzazione di diversi seminari e convegni, la progettazione e la realizzazione di lavori di ricerca e di percorsi formativi, che ne hanno progressivamente consolidato l’identità e l’impegno incoraggiandoci – in questa occasione di dibattito – ad una condivisione con la comunità scientifica pedagogica e, in particolare, con la S.I.PED. Il presente intervento intende, quindi, illustrare il nostro approccio alla ricerca nell’ambito dell’educazione degli adulti: i quesiti, le ipotesi, gli argomenti, i metodi, i progetti e le attività, in estrema sintesi, il percorso compiuto e le direzioni in cui intendiamo proseguire. Tenendo saldo, ed alimentando, un orizzonte di senso educativo attento ad incrementare le possibilità di realizzazione umana e a tutelare un progetto antropologico di cura per la qualità della vita, che trova nell’educazione il suo perno e che è consapevole dei rischi di strumentalizzazione e dei riduttivismi che non di rado si celano nell’universo formativo contemporaneo, oltre che nelle logiche utilitaristiche che tendono a dominarlo

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
Adult education in Italy: epistemological and political issues
No full textThis contribution aims to present the current situation of Adult Education in Italy. The paper is organized in two parts: the
first one (paragraphs 2 and 3) concerns the debate on academic discipline, with particular attention to the epistemological location of Adult Education. The second one (paragraphs 4 and 5) presents the actual education system for adults and it illustrates the bill of reform that Italian Parliament is debating for some years. This part also explains why this reform has been treated by teachers, trade unions associations and school leaders with reluctance. The paper has been designed jointly by the two authors. The writing of the “Abstract”, “Introduction” and “References” is common, whereas are attributed to Elena Marescotti paragraphs 2 and 3, and to Matteo Cornacchia paragraphs 4 and 5
Analysis of particle size distribution in municipal wastewaters
No full textInnovative membrane filtration plants for municipal wastewaters are being developed and need the support of reliable filtration models in the designing phase. In the past, semi-empirical filtration models for membrane processes have been proposed. At present, the most prominent works point out the importance of particle poly-dispersity in the development of reliable models but fail into the implementation of probability density functions (PDFs) capable of an accurate fitting of the experimental particle size distribution (PSD). We report the experimental PSDs of two different municipal wastewater samples, obtained through the laser diffraction technique. The experimental results show that the laser diffraction technique can characterize wastewater particle dimensions both in the colloidal and supra-colloidal regions. The experimental study is complemented by a comparative analysis in which many PDFs are used to fit the experimental PSDs through a least-squares approach. Some of these PDFs are proposed here for the first time to fit experimental wastewater PSDs. Among the PDFs considered for the statistical modeling, the three-parameter lognormal and the Burr PDFs are demonstrated to provide satisfactory fitting, whereas the other considered functions fail. This result is confirmed by the analysis of both the available wastewater samples
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
