Gestalt/Gestalt Theory
2020
Gestalt is a concept introduced to solve the problems of unity, connection and order that objects manifest in experience. Philosophers trained at Franz Brentano’s teaching began to work on it to address epistemological and ontological questions about perception, cognition and the structure of objects. This work was seminal for Gestalt psychology, from the research of the Graz and Berlin Schools, carried on by Cesare Musatti, Fabio Metelli, Gaetano Kanizsa, Paolo Bozzi in Padua and Trieste, Albert Michotte and Paul Fraisse in Louvain, to that of Edgar Rubin and David Katz, but also of Karl Buhler, Egon Brunswik and Ludwig Kardos in Wien. Common is the tenet that the world looks as neither a …

Green Composites Based on Mater-Bi® and Solanum lycopersicum Plant Waste for 3D Printing Applications
2023
3D printability of green composites is currently experiencing a boost in importance and interest, envisaging a way to valorise agricultural waste, in order to obtain affordable fillers for the preparation of biodegradable polymer-based composites with reduced cost and environmental impact, without undermining processability and mechanical performance. In this work, an innovative green composite was prepared by combining a starch-based biodegradable polymer (Mater-Bi®, MB) and a filler obtained from the lignocellulosic waste coming from Solanum lycopersicum (i.e., tomato plant) harvesting. Different processing parameters and different filler amounts were investigated, and the obtained sample…
Guided Wave Techniques for Damage Detection in Composite Aerospace Structures
2018
Composite materials make up an increasing portion of today’s aerospace structures (see, e.g. Boeing 787 and Airbus 380). These aircrafts’ fuselage, for example, is composed of a laminated composite skin connected to composite stringers and C-frames. Of primary importance is the detection of damage in these built-up structures, whether caused by the manufacturing process or in service (e.g. impacts). A related issue is the characterization of the composite (visco)elastic mechanical properties, that can also be related to the quantification of potential damage. Guided elastic waves propagating in the ~100s kHz regime lend themselves to provide the necessary sensitivity to these two conditions…
I diritti umani come tema conflittuale nel Consiglio di Sicurezza delle Nazioni Unite
2019
With the end of the Cold War and the expansion of the international liberal order, human rights have entered the UN Security Council agenda. However, this has become a divisive issue. In a context of greater influence of the US and its Western allies over the decision-making process of the most important multilateral institutions, the UN above all, the interpretation allowing intrusive practices by the Security Council promoted by the Western permanent members has clashed with the defense of sovereignty promoted by Russia and China. Analyzing divisive resolutions with reference to human rights in the period 2001-2017 (Lebanon, Myanmar, Zimbabwe, Libya and Syria) and the only thematic meetin…
IMMAGINAZIONE FILMICA E FANTASCIENZA NELL' EDUCAZIONE DEI GIOVANI
2018
Questo articolo rivaluta l’esperienza filmica come un’occasione di apprendimento per i giovani, nei quali provoca un’immaginazione che permette loro di dotare di nuovi significati la realtà. In particolare, il cinema di fantascienza viene considerato un passaggio imprescindibile per la formazione dell’identità della persona, sia per l’aspetto avventuroso, che conduce gli spettatori ad una graduale metamorfosi da una fase ingenua ad una visione più realistica di se stessi, delle cose e degli altri, sia per la vocazione utopica, cioè per la capacità di immaginare il futuro che fornisce loro un modo per conoscere il presente, recuperare la memoria storica e progettare il futuro. This paper re-…
