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
CHANGING MINDSET IN SCHOOL TEACHERS. THE STRANGE CASE OF THE ITALIAN NATIONAL PLAN FOR DIGITAL SCHOOL AND THE H-MOOC ON CODING
No full textThe National Plan for Digital School (PNSD 2015) is one of the main components of “La Buona Scuola”, the national policy program to modernize the K-12 schools system in Italy. Born as a deliberative policy-making process, indeed la Buona Scuola has been bitterly contested because of its general aim to reinforce and responsibilize the school leadership, thus reducing the general sense of collegial participation in school and program management. On the other hand, however, the school system in Italy has never experienced such a level of bottom up participation, engagement, and centrality in government policies, with a positive effect on allocated funds for reengineering education, renewal of school buildings, and creation of new skills and pedagogies in teacher education. One billion Euro has been, in fact, allocated to the National Plan for Digital School in order to bring broadband and connectivity in all K-12 institutions, to create a generation of tech savvy teachers, to provide educational opportunities to all the field personnel, to elaborate and implement a consistent strategy for learning by doing, problem solving, and lab-based teaching initiatives. Moreover, the national strategy aims at laying a common ground for basic skills both in teachers and learners, experimenting with new approaches and at the same time, inviting teachers to become researchers in their field. The need for repositioning education is well supported by some data: an inquiry by OCSE TALIS (2013) sees Italy in first place for teacher training and educational needs in ICTs, with 36% of teachers investigated declaring themselves to be insufficiently prepared for technology-enhanced teaching against an average rate of 17%.
Considered as a central pillar of “La Buona Scuola”, the PNSD intends to propose a strategic vision regarding 21st century education, using digital not as a means but as a game-changer that is able to push for organizational change, to leverage key education resources (mainly human), to promote open educational resources (OER) and professional skills development. In other words, to re-position the italian education system on the global market. It seems to be a complete change of paradigm. Coding has been recognized by the PNSD as a fundamental discipline to be introduced at schools to develop computational thinking skills, with a non secondary effect: to converte the teacher role into an enabler factor, giving to it new centrality, legitimation and social value.
The MOOC on Coding has been offered through the European Multiple MOOC Platform (europeanmoocs.eu, Emma for short). The MOOC has been organized as a hands-on experience course, that is mainly based on live webinars illustrating how to organize coding activities using only freely accessible online resources. This approach allows them to learn the fundamental principles of coding together with their pupils and to apply computational thinking to any topic. Considered as a transversal skill, the objective of such a MOOC was to restore the centrality of the teacher in the Italian school system through a highly scalable process of teaching/learning among the diverse actors involved: coding ambassadors, teachers and digital animators, pupils as final users. In this paper, we will explore the dimension of the experience, the relevance of pedagogies used, as well as the factors of success with empirical data on user profiles, previous learning experience as well completion rate
On demand e serialità. L’informazione politica si fa push
No full textL’ultima edizione del Digital News Report (2023)1, pubblicato dal Reuters Institute for the Study of Journalism dell’Università di Oxford, documenta come l’informazione digitale stia cambiando formati e canali di fruizione. Se solo poco più di un quinto delle persone accede oggi alle notizie da siti e app dei giornali, diventano sempre più popolari le newsletter e i podcast. Cambiano le traiettorie della sostenibilità con un aumento dell’accesso
a pagamento: negli Stati Uniti il 56% degli intervistati sottoscrive un abbonamento,
l’8% di questi paga per ricevere una newsletter, il 5% per un podcast. In UK solo il 9% accede a prodotti news a pagamento, ma il 30% ha ascoltato almeno un podcast nell’ultimo mese. In Italia i sottoscrittori raggiungono il 12% e gli utenti podcasts oltre il 30%. Naturalmente, ogni paese fa storia a sé, ma l’indagine fornisce indizi di una inversione di tendenza del fenomeno noto come news-finds-me-perception, vale a dire la percezione diffusa che, attraverso i social, le notizie raggiungano gli utenti anche in presenza di comportamenti passivi di consumo (Gil de Zúñiga e Cheng, 2021). Va consolidandosi, dunque, la ricerca di informazione di qualità e la volontà di sostenere testate o esperti cui si attribuisce credibilità e fiducia (Fig. 1). Newsletter e podcast sono formati non nuovi, che si stanno ora giovando di quella cultura della serialità diffusa da piattaforme come Netflix. Tecnologie cosiddette
push, che garantiscono un alto livello di selezione e qualità editoriale, una fruizione on demand e uno stile narrativo fresco. In questa rubrica ne proponiamo alcuni esempi con una decisa preferenza per i canali di informazione politica e con un occhio a quelle iniziative che stanno diventando veri e propri asset strategici per la brand loyalty e la diversificazione delle audience, anche delle grandi testate

No full textVariations 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
