The use of video narration to develop soft skills in initial teacher training
Full text linkThe narrative dimension allows us to understand reality and to organize knowledge in a hermeneutical and open way. It is also able to generate reflective learning and to stimulate skills that are not necessarily subject related. When narration turns into video narration, video production and artefact building processes can promote the development of soft skills, to be improved during the academic path and put into practice in future professional actions. This article presents the main results of an empirical study of a blended/hybrid digital video-narrative laboratory proposed to 132 university students doing undergraduate initial teacher training, extrapolated from a wider mix-method research study conducted at the university level. The study currently has the limitations of focusing on a single teaching area, but the encouraging results could be a stimulus to expand research on the use of video across the entire teacher training curriculum
La distanza e la vicinanza: formazione e tecnologie a sostegno di una comunità professionale di servizi per l’infanzia,
No full textLa “competenza digitale” continua a figurare tra le competenze fondamentali allo scopo di rispondere alle esigenze indotte dalla New/Net/Knowledge Economy e superare nuove forme di digital divide.
Attualmente si ravvisa sempre più significativa la connessione tra i temi del framework DigCom 2.1 e gli obiettivi dell’Agenda 2030 declinati in termini di sostenibilità, accessibilità e inclusione per promuovere un’istruzione di qualità (obiettivo 4) e il contrasto alle povertà, tra cui anche quella educativa (obiettivo 1). Nell’ambito del percorso di formazione per lo sviluppo di innovazione digitale rivolto ai coordinatori pedagogici dei servizi e delle scuole dell’infanzia (CPT Parma), svolto tra il 2018-19 e continuato nel 2020 a supporto dell’emergenza pandemica, è stata svolta un’indagine rivolta al personale educativo, educatori e coordinatori, dei servizi. Il contributo vuole mettere in luce alcuni aspetti di questa indagine per far
emergere lo stato dell’arte dell’uso e delle credenze riguardo le tecnologie digitali nelle relazioni professionali orizzontali e con le famiglie, ma anche nelle concrete proposte di attività educative. Interessante è il confronto tra usi e abitudini prima e dopo la prima ondata pandemica per elaborare alcune indicazioni che siano di orientamento per il futuro del Coordinamento Pedagogico Territoriale
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
Design smart city apps using activity theory.
Full text linkIn this paper we describe an innovative approach to the design process of Smart City interventions. We tested it with participants enrolled in the Master’s Degree program in “Innovators in enterprise and public administration”: the objective of the Master was to stimulate the acquisition of technical and methodological skills useful in designing and implementing specific Smart City actions. During the "project work" phase, participants learned about a design method named SAM – Smart City Model - based on the Cultural Historical Activity Theory (CHAT). We present an overview of design criteria for Smart City projects, the description of the theoretical framework of Activity Theory, and our proposal of the SAM design model. We also present some examples of student’s “projects” and a more extensive description of one case study about the full design process of an App planned using SAM, for “smart health” vaccine management and monitoring services. The App was later published and made available to the citizens and was successful in attracting thousands of users. All the participants considered the model very useful in particular because it made possible to understand the interaction and solve contradictions between different stakeholders and systems involved
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
Caratterizzazione geotecnica e analisi di stabilità degli argini del Fiume Tevere in tre siti nel tratto compreso tra Castelgiubileo e la foce
No full textL'articolo riassume i risultati di uno studio finalizzato alla caratterizzazione dello stato di ammaloramento degli argini esistenti del fiume Tevere nel tratto compreso tra Castelgiubileo e la foce. Le indagini e le analisi geotecniche sono state concentrate in tre siti campione, tipologicamente rappresentativi. La caratterizzazione geotecnica dei corpi arginali e dei terreni di fondazione in ciascuno dei tre siti è basata su un'estesa campagna di indagini in sito e in laboratorio. Per valutare le condizioni di stabilità e il margine di sicurezza degli argini nei tre siti sono state eseguite analisi di stabilità utilizzando il codice agli elementi finiti Plaxis, considerando le distribuzioni delle pressioni interstiziali indotte da tre diverse condizioni idrometriche del fiume: livello ordinario, massima piena, svaso dopo il passaggio dell'onda di piena. Le azioni sismiche sono state portate in conto mediante un approccio pseudostatico. I fattori di sicurezza calcolati risultano in generale accettabili in confronto ai valori minimi prescritti dalla normativa (NTC2008)
Hair analysis by GC[sol ]MS[sol ]MS to verify abuse of drugs.
No full textBecause of its peculiar characteristics, hair analysis provides a way of obtaining information that cannot be acquired by other commonly used forensic medical analyses, such as blood or urine analysis. In the keratin matrix many xenobiotics are incorporated permanently, in contrast to the situation with blood or urine where they are generally only detectable for a few hours or days. Therefore hair analysis should be the method of choice in the clinical and forensic toxicology field when the assessment of repeated or chronic exposure to a drug is required, e.g. in the case of criminal responsibility, revocation/restoration of a driving licence or in workplace testing. Some factors that can affect the concentrations of drugs in hair, such as passive contamination, age, ethnicity and cosmetic treatment, must be considered. Analytical methodology is also very important: GC/MS/MS has proved to be a highly sensitive and specific technique for the detection of very low concentrations of such drugs in hair. In this study five cases of the application of hair analyses using this technique for the determination of abused drugs (opiates, cocaine, amphetamine, anabolic steroids) are described
