No full textThe exhibition, dedicated to the middle register of Schifanoia's frescoes, took place in Iuav till 14th march 2013. Edited by Marco Bertozzi (University of Ferrara) and Monica Centanni (University Iuav of Venice), and designed by Olivia Sara Carli and Emma Filipponi, it proposes a comprehensive vision of the astrological register of the Hall of Months of Schifanoia Palace. The show moves from an introductory section, dedicated to the historical and artistic context, throughout the seven conserved months, and ends with the pictorial reconstruction of the destroyed ones, made by Maurizio Bonora

New advances in the study of local structure of molten binary salts
No full textAccurate extended x-ray absorption fine structure measurements of molten RbBr and CuBr are analyzed and compared with computer simulations and neutron diffraction results. Advanced multiple-edge ab initio methods are used for data analysis. The short-range cation-anion pair distribution function of liquid RbBr is found to be in agreement with previous molecular dynamic simulations confirming the accuracy of present theoretical models. In liquid CuBr, due to the exceptional short-range, sensitivity, direct evidence for nearly covalent bonding is obtained, improving previous neutron diffraction determinations. Possible important consequences of present results for experimental studies of binary liquid systems are addressed
Development of a deep karst system within a transpressional structure of the Dolomites in north-east Italy
No full textThe Piani Eterni karst system is one of the longest and deepest caves of Italy situated in the southern sector of
the Dolomiti mountain range. The area where the cave was formed displays peculiar structural settings confined
in a tectonic transpressive corridor between two regional thrusts (Belluno and Valsugana). During Miocene
uplift of the range the inheritance of Mesozoic structures led to the formation of a deep and wide
upward-branching flower (or palm tree) structure cutting the carbonate sequence and exposing the surrounding
surface to karst processes after erosion. The relative lowering of the hydrologic base level, due
both to the uplift of the area and then to the carving of deep glacial valleys in the Quaternary, allowed the
formation of paleo-phreatic conduits at subsequently deeper levels, interconnected by vadose shafts and
canyons.
This work gives a detailed tectonic interpretation of the transpressive structure and picks out the tectonic features
most favorable to the karst development. A detailed statistical analysis of the distribution and orientation
of the karst conduits was performed using 31 km of 3D surveys showing that the development of the
cave was strictly guided by a few favorable surfaces of stratigraphic and tectonic origin. These features are
known in the literature as inception horizons and tectonic inception features, respectively. Cave levels are
usually related to lithologic favorable conditions associated with standings of the paleo-water table. Here
we suggest that some tectonic surface geometries could have led to the opening of voids in the active tectonic
phase leading to the formation of the original proto-conduit network. Different types of tectonic inception
features identified in the cave were described in terms of geometry and kinematics. Tensional fractures, as
well as fault plane undulations and flexural slip surfaces between beds, are described as the most favorable
tectonic surfaces for the development of the conduits. Finally, we discuss why transpressional settings and
related flower structures in soluble rocks can enhance the karst process allowing the formation of huge
and deep karst systems
Urban Tree CO<sub>2</sub> Compensation by Albedo
No full textUrban form and surface properties significantly influence city liveability. Material choices in urban infrastructure affect heat absorption and reflectivity, contributing to the urban heat island (UHI) effect and residents’ thermal comfort. Among UHI mitigation strategies, urban parks play a key role by modifying the microclimate through albedo and evapotranspiration. Their effectiveness depends on their composition, such as tree cover, herbaceous layers, and paved surfaces. The selection of tree species affects the radiation dynamics via foliage color, leaf persistence, and plant morphology. Despite their ecological potential, park designs often prioritize aesthetics and cost over environmental performance. This study proposes a novel approach using CO2 compensation as a decision-making criterion for surface allocation. By applying the radiative forcing concept, surface albedo variations were converted into CO2-equivalent emissions to allow for a cross-comparison with different ecosystem services. This method, applied to four parks in two Italian cities, employed reference data, drone surveys, and satellite imagery processed through the Greenpix software v1.0.6. The results showed that adjusting the surface albedo can significantly reduce CO2 emissions. While dark-foliage trees may underperform compared to certain paved surfaces, light-foliage trees and lawns increase the reflectivity. Including evapotranspiration, the CO2 compensation benefits rose by over fifty times, supporting the expansion of vegetated surfaces in urban parks for climate resilience
MABS validation through repeated execution and data mining analysis
No full textAgent Based Modelling is the most interesting and advanced approach for simulating a complex system: in a social context, the single parts and the whole are often very hard to describe in detail. Besides, there are agent based formalisms which allow to study the emergency of social behaviour with the creation and study of models, known as artificial societies. Thanks to the ever increasing computational power, it's been possible to use such models to create software, based on intelligent agents, which aggregate behaviour is complex and difficult to predict, and can be used in open and distributed systems. Data mining is born in the last decades in order to help users in finding useful knowledge from the otherwise overwhelming amount of data available nowadays from the web and the data collected every day by companies. Data Mining techniques can therefore be the keystone to reveal non-trivial knowledge expressed by the initial assumption used to build the micro-level of the model and the structure of the society of agents that emerged from the simulation
Using overt and covert items in self-report personality tests: Susceptibility to faking and identifiability of possible fakers
No full textSelf-report personality tests widely used in clinical, medical, forensic, and organizational areas of psychological assessment are susceptible to faking. Several approaches have been developed to prevent or detect faking, which are based on the use of faking warnings, ipsative items, social desirability scales, and validity scales. The approach proposed in this work deals with the use of overt items (the construct is clear to test-takers) and covert items (the construct is obscure to test-takers). Covert items are expected to be more resistant to faking than overt items. Two hundred sixty-seven individuals were presented with an alexithymia scale. Two experimental conditions were considered. Respondents in the faking condition were asked to reproduce the profile of an alexithymic individual, whereas those in the sincere condition were not asked to exhibit a particular alexithymia profile. The items of the scale were categorized as overt or covert by expert psychotherapists and analyzed through Rasch models. Respondents in the faking condition were able to exhibit measures of alexithymia in the required direction. This occurred for both overt and covert items, but to a greater extent for overt items. Differently from overt items, covert items defined a latent variable whose meaning was shared between respondents in the sincere and faking condition, and resistant to deliberate distortion. Rasch fit statistics indicated unexpected responses more often for respondents in the faking condition than for those in the sincere condition and, in particular, for the responses to overt items by individuals in the faking condition. More than half of the respondents in the faking condition showed a drift rate (difference between the alexithymia levels estimated on the responses to overt and covert items) significantly larger than that observed in the respondents in the sincere condition
