Quantum physics at high school: a collaboration between physics researchers and teachers to design teaching - learning sequences
Full text linkQuantum physics is changing the paradigms for understanding reality and is fostering scientific innovation. Nevertheless, the core concepts of the second quantum revolution are not included in the Italian physics curriculum. Our research project aims to generate the conditions for the development of the scientific competences related to the understanding of the fundamental concepts of contemporary physics at secondary school level. In the framework of Educational Reconstruction for Teacher Education (ERTE), we have developed a continuous professional development program for teachers to enable in-service physics teachers in secondary schools to introduce the superposition principle, quantum entanglement, and their technological applications into regular classroom activities. To achieve this goal, several types of activities have been planned to strengthen collaboration between high school teachers and physics researchers. The intended outcome is to create resources and materials that can help teachers and researchers create innovative physics curricula that can be used in normal secondary school teaching activities. In this paper we present the results of the first edition of a continuous professional development program for in-service teachers on introducing the superposition principle and quantum entanglement into online classroom activities during the schools Covid19 lockdown
Il progetto interateneo delle Università degli Studi di Camerino e Macerata: la nascita di 'Eratosthenes' e 'Aretusa'
No full textScopo del Progetto è stata quello di elaborare un percorso divulgativo-culturale, che in modo interdisciplinare si muovesse intorno a tematiche tra archeologia, storia, geologia attraverso il linguaggio dell'arte, in particolare del teatro. Ne è scaturita la creazione di "Aretusa - Canto delle acque nelle Metamorfosi", che, insieme al precedente 'Eratostene: il volto della terra', rappresenta un libretto teatrale intorno alla natura, in particolare l'Acqua, in cui la mitologia, le fonti letterarie e iconografiche forniscono il pretesto narrativo e la materia per la rappresentazione. I luoghi e i miti di Cirene in Libia per 'Eratostene' e della Sicilia antica per 'Aretusa' rivivono nei temi e nelle geo-ambientazioni dei due libretti (Autore: geologo F. Pallotta; consulenza scientifica: archeologi E. Catani; E. Stortoni). Entrambi gli Atenei hanno fatto circuitare l'opera con il coinvolgimento di attori-studenti nei teatri storici e antichi delle Marche e della Sicilia
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

No full textLibyc territory preserves again wide archaeological treasures of these millenarian stratifications of civilization – Roman and Greek period in particular – with stately urban settlements, destroyed long centuries and buried under sand piles. The ancient buried cities as Sabratha, Leptis Magna, Euesperide, Tocra, Tolemaide, Apollonia and Cyrene (the so called “ Athen of Africa”), represent one of the most important and big archaeological layer of the mediterranean basin. The Apollonia area belongs to a wide coasting plateau, extended in WE direction, which represents the most highest point of Cyrenaica region. Actually for the problems due to the sinking of the ground and the sea rise level showed above, the coastal area of Apollonia has the real necessity to be protected to stabilize the zone to avoid that the sea puts in danger the historical area. We propose to define a two-sided technical group – that involves, of course, by italian and libyan governative people – that can work starting from this draft, on writing a detailed technical report, aimed to protect the libyan coastline and its important archaeological heritage
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
