Molte vie, una sola direttrice. Infrastrutture e geopolitica tra Mediterraneo Allargato e Oceano Pacifico
No full textLe infrastrutture disegnano in epoca contemporanea come nel passato dinamiche del potere sia a livello regionale che globale. BRI ha significato un'azione della Cina ben precisa volta a contrastare l'egemonia occidentale sul Rimland, ridefinendo traiettorie terrestri e marittime in grado di sviluppare dinamiche geopolitiche ben precise. L'occidente e, in generale, i paesi antagonisti della Cina, organizzano piani concorrenti. Uno di questi è IMEC, il corridoio europa medioriente India, che vorrebbe contrastare la crescente influenza cinese nell'arco territoriale tra India e Mediterraneo. Tutti questi progetti e iniziative sono tasselli di un disegno egemonico che vuole tendere al controllo delle vie di comunicazione tra Atlantico e Pacifico.Infrastructure draws both regional and global power dynamics in contemporary times as in the past. BRI signified a very precise action by China to counter Western hegemony over the Rimland, redefining land and sea trajectories capable of developing very precise geopolitical dynamics. The West and, in general, countries antagonistic to China, organise competing plans. One of these is IMEC, the Middle East-India corridor, which would like to counter China's growing influence in the territorial arc between India and the Mediterranean. All these projects and initiatives are pieces of a hegemonic design that aims at controlling the communication routes between the Atlantic and the Pacific
Eco-design teaching initiative within a manufacturing company based on LCA analysis of company product portfolio
Full text linkEco-design is the integration of environmental considerations within product design and development. Eco-design represents an important innovation driver for companies; however, well-known barriers limit the diffusion of this design paradigm in the industrial world. Amongst these, lack of eco-knowledge is correlated to the adopted eco-design teaching methods. Previous experience has highlighted that traditional teaching methods such as university lectures or refresher courses are not an effective means for disseminating eco-design knowledge in the industrial world.In this context, the present paper proposes a novel eco-design teaching method based on a transformative strategy for promoting eco-design and facilitating the learning process.This approach, tested in collaboration with an Italian manufacturing firm, is considered the first attempt to implement a repeatable eco-design teaching approach that can be scaled up in different industrial contexts. Several company departments, including management, marketing and commercial affairs, design and engineering, and a testing laboratory were involved in the training program. Technical results show that company employees were able to autonomously implement re-design solutions and improve the environmental performance of a coffee machine upon completion of the course. The quantitative evaluation of formative outcomes through assessment before and after the course highlights a significant increase in the awareness of personnel and knowledge relating to eco-design.

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 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
Modeling M3 RR Lyrae light curves
No full textNonlinear convective pulsation models of RR Lyrae stars are used to obtain a theoretical fit of the observed light curves for a number of pulsators in the Galactic globular cluster M3, with the purpose of constraining their intrinsic stellar parameters and the cluster distance modulus. The dependence of the fit quality on the input stellar properties is investigated and the self consistency of the adopted theoretical scenario is discussed
