Eighth International Symposium “Monitoring of Mediterranean Coastal Areas. Problems and Measurement Techniques” : Livorno (Italy) June 2020. PROCEEDINGS E REPORT
No full textThe 8th International Symposium Monitoring of Mediterranean Coastal Areas. Problems and Measurements Techniques was organized by CNR-IBE in collaboration with FCS Foundation, and Natural History Museum of the Mediterranean and under the patronage of University of Florence, Accademia dei Geogofili, Tuscany Region and Livorno Province.
It is the occasion in which scholars can illustrate and exchange their activities and innovative proposals, with common aims to promote actions to preserve coastal marine environment. Considering Symposium interdisciplinary nature, the Scientific Committee, underlining this holistic view of Nature, decided to celebrate Alexander von Humboldt; a nature scholar that proposed the organic and inorganic nature’s aspects as a single system. It represents a sign of continuity considering that in-presence Symposium could not be carried out due to the COVID-19 pandemic restrictions. Subjects are related to coastal topics: morphology; flora and fauna; energy production; management and integrated protection; geography and landscape, cultural heritage and environmental assets, legal and economic aspects

No full textYou get what you deserve, how the belief in a just world changes physiological response towards adverse stimuli.
No full textAccording to Lerner’s Just World Theory (1980), during their life human beings are exposed to a plethora of experiences that shape their idea of a “Just World” which will have an important role in guiding them in their life’s choices. The present study aims to investigate the influence of individuals' perceptions of a just world and their moral values in the physiological response (the pupil dilation) towards adverse stimuli. For this purpose, an ad hoc experiment was conducted where participants were primed to see the world as just or unjust using a framing technique and asked to look at a set of images representing negative events happening all over the world. Participant’s morality was also assessed using the Moral Foundation Questionnaire (Graham et al., 2008). Although there was no main effect of the type of framing (just world/unjust world) on pupil dilation, a two-way interaction shows that participants who gave more importance to binding foundations had a greater response (a constriction of the pupil, that is a type of activation, Bradley et al., 2006) towards adverse stimuli when they see the world as unjust. Possible present and future implications are discussed

L’Influenza del livello di costrutto nell'intenzione all'azione collettiva
No full textLa Construal Level Theory (CLT) afferma che la distanza psicologica può influenzare il modo in cui le
persone concepiscono e strutturano nella propria mente le cose, gli eventi e persino le altre persone. Nello
specifico, un'elevata distanza psicologica porta le persone ad avere un mindset ad alto costrutto (astratto),
concentrandosi sul "fine" delle cose, mentre una bassa distanza psicologica porta le persone ad avere un
mindset a basso costrutto (concreto), concentrandosi sui "mezzi" delle cose. La ricerca proposta mira ad
indagare se e come il diverso tipo di mindset suscitato dalla distanza psicologica possa influenzare
l'intenzione delle persone di agire collettivamente a favore e contro la disuguaglianza economica, tenendo
conto del possibile effetto di mediazione della Giustificazione del Sistema Economico (ESJ; la tendenza
motivazionale a percepire il sistema economico di riferimento come giusto, legittimo e naturale). Per tale
obiettivo di indagine, è stato condotto uno studio sperimentale (N = 392) in cui è stata prima manipolata la
distanza psicologica e, successivamente, sono state misurate le credenze di giustificazione del sistema
economico e le intenzioni di azione collettiva a favore e contro la disuguaglianza economica in Italia. I risultati di analisi di mediazione semplice hanno rivelato che un alto livello di costrutto (vs. basso)
manipolato attraverso la distanza temporale ha un effetto indiretto significativo e negativo sull'intenzione di
partecipare alle azioni collettive contro la disuguaglianza economica attraverso alta ESJ. Al contrario, un alto
livello di costrutto (vs. basso) ha un effetto indiretto significativo e positivo sull'intenzione di partecipare alle
azioni collettive a favore della disuguaglianza economica attraverso alta ESJ. I risultati ottenuti dimostrano
che un mindset di tipo astratto (vs. concreto), centrato quindi solamente su caratteristiche principali, può
contribuire al mantenimento della disuguaglianza economica, riducendo le intenzioni di azione collettiva
volte al cambiamento sociale e aumentando quelle volte alla stabilità sociale
Creep modelling of 316H stainless steel over a wide range of stress
No full textInvestigation of material creep behaviour in the diffusion controlled creep regime is often unfeasible because of the long duration associated with low stress levels. On the other side, extrapolation from higher creep rates usually provides inaccurate results because of the sharp change in the data trend as a result of the change in the governing deformation mechanism from dislocation to diffusion type controlled creep. Similarly, extrapolation based on creep models, which have been formulated and validated mainly for dislocation type creep (such power law creep with the creep exponent ranging from 6 to 9), underestimates the actual creep rate significantly. Recently, Bonora and Esposito (2010) developed a mechanism-based model (BE model) capable to account for deformation and damage mechanism occurring in creep. In this work the BE model was applied to AISI 316H stainless steel for which considerable creep data in both dislocation and diffusion temperature/stress controlled regime were available. Using the same data set, the predictive capabilities of several models were compared
A non-invasive capacitive sensor strip for aerodynamic pressure measurement
No full textThis paper presents a capacitive pressure sensor strip implemented in general purpose printed circuit board (PCB) technology based on a thin 3D structure composed of polyimide, woven glass reinforced epoxy resin (FR4) and metal layers. Multiphysics finite elements method (FEM) simulations have been performed over the proposed structure in order to develop a time-dependent electrical and mechanical model that can be easily used to tailor the characteristics to the application. The device targets a wide class of fluid dynamics applications, being non-invasive, comformable and smart for placement. The device simulations are herein validated by experimental wind tunnel measurements and compared with figures obtained on a wing profile by conventional electromechanical pressure transducers. This approach is one of the first example of fully embedding and electronically controlled fluid flow monitoring apparatus that could be used in replacement of state of the art mechanical systems
New Scenarios for a Development between Infrastructures and Innovation
No full textBoth infrastructure and research, make communications and exchanges between distant places possible. As a consequence, geographic positions and administrative borders are less and less significant compared to the polarity of the individual cities. From the port and infrastructural systems’ point of view, Trieste, can closely resemble this model by strengthening the two drivers for development, quality of life and employment opportunity. The specificity that needs to be investigated is the complex system that joins port logistics with innovation promoted by AREA Science Park among others
Design of Finite State Machines for SRAM-based FPGAs operated in radiation field
No full textFor the CERN LHC Run 3, the ALICE experiment completely redesigned the Inner Tracking System (ITS), which now consists of seven cylindrical layers instrumented with 24 120 Monolithic Active Pixel Sensors, covering an area of 10m . The ITS is controlled and read out by 192 custom Readout Units, which employ commercial SRAM-based FPGAs and will operate in a radiation field, requiring specific FPGA design to ensure system reliability. This contribution focuses on the techniques developed for designing radiation tolerant finite state machines, discussing the theoretical background, the actual implementation, and their validation with fault injections and proton irradiation tests
Monitoring of Mediterranean Coastal Areas problems and measurement techniques. EIGHTH INTERNATIONAL SYMPOSIUM Livorno (Italy) June 2020
No full textMORPHOLOGY AND EVOLUTION
OF COASTLINES AND SEABEDS
The session "Morphology and evolution of coastlines and seabeds" has faced a
theme that is becoming increasingly important because coastal areas are characterized by
high-anthropic pressure, relevant socioeconomic interests besides being very sensitives to
the effect of climate changes.
The title of the session aims to underline how the coastal areas are a multifaceted
system constituted by both emerged and submerged areas that are in continuous and mutual
evolution.
Although the symposium starting date had unfortunately fallen during the Covid-19
emergence, several international and national researchers have brought their contributions
to the session.
The issues addressed, mainly concern a series of case-histories (Italy, Spain,
Turkey and Croatia) illustrating coastline changes along the time and, in some instances,
their relationships with beach nourishment or coastal defenses. Studies about the influence
of fluvial sedimentary supply on the offshore area and the effects of intensity water
circulation in strongly anthropized areas are also presented. The acquisition of data of the
scientific contributions derives from different approaches:
i) analysis of aerial and satellite images,
ii) laboratory analyses of samples collected in the study area,
iii) experimental tests.
Gomes da Silva et al. show how the use of automatic co-registered Landsat and
Sentinel-2 satellite images allows them to obtain accurate shoreline series in the Tordera
Delta area (Spain).
A complementary approach is proposed by Pagán et al. that analyses aerial images
spanning from 1956 to 2019 and reconstruct the coastal evolution along the Alicante coast
(Spain) testing the impact of beach nourishment that occurred since the 1990s.
Similar is the methodological approach proposed by Kadri and Atroune to
evaluate the diachronic evolution of the Bordj El Kiffane coastline (Algeria) with respect to
the presence or absence of protection structures.
Piccioli-Resta et al. have utilized a remotely piloted aircraft systems (RPSA) along
the Lecce coast (Italy), for the monitoring of the beach dunes and the nearby shorelines.
A similar technique was also utilized by Bedini et al., to monitoring
the Poseidonia oceanica meadows evolution in the Follonica and Baratti gulfs (Italy). The
drone-survey has evidenced the unsuitability of the coastal defenses used up now.
A direct sedimentological approach is proposed by López et al. to investigate,
within three beaches located in Spain, the relationship between sediment wear and shoreline
evolution through the use of the accelerated particle wear test (APW).
Pikelj and Furčić analyze several seabed samples collected in front of a coastal
cliff subjected to erosional processes at the Vrgada Island, in Croatia. The data furnish new

information about the impact of cliff erosion on coastal sediments supply and on their
longshore redistribution.
Di Leo et al. present a sedimentological and geochemical-based study to establish
the influence of the Sarno river on the present-day sedimentation in the Naples (Italy) bay
evaluating grain size, the presence of organic matter, and the pollution degree of the
sediments samples collected in the offshore area of the bay.
Bulkan et al. use a stratigraphic perspective to infer the depositional coastal
evolution of the Lake Bafa area (Aegean coast, Turkey), which occurred during the last
3,5 ka. Through the study of six cores, they document the succession of four phases, from
the earlier marine-dominated stage to the present-day isolated lacustrine stage.
Finally, Di Natale et al. by means of the implementation of experimental tests of a
three-dimensional physical model, carry out an evaluation of the intensity water circulation
within marinas and defense structures located in relevant sites of Italy (Salerno and
Ischitella stretch of coast along with the harbors of Fiumicino Manfredonia and
Castelvolturno).
