Truth (bearers) pluralism
As for many other properties, to understand the nature of truth attention should be paid to the kind of entities that are apt to bear it. In particular, I argue that different kinds of truth bearers tend to support different properties of truth. After that, I show that there are reasons to admit a plurality of truth bearers. As a consequence of these two results, a plurality of truth properties may be naturally admitted. The general upshot of the paper is a new way to motivate alethic pluralism, which stems from considerations on the nature of representations rather than from considerations on what is represented. This new version of truth pluralismâtruth (bearers) pluralismâis shown to be theoretically fertile and promising against some standard criticisms
Truth and the Unity of Logical Validity
According to a traditional view, logical validity consists in necessary truth preservation. Such an account has been argued to carry an apparent commitment to a unique property of truth to be preserved from premises to conclusion. Recent discussions, however, have concluded that if the metaphor of truth preservation is carefully unpacked, no need for a unique property is there. All is needed is that certain structural relations among instantiations of truth properties hold. Against this view, we argue that a unique general truth property is indeed required by logical validity. We first show that the unpacking should be correctly understood since it imposes constraints on the concept and the properties of truth. We then demonstrate that, under such constraints, a general property is not imposed by truth preservation but by another feature of validity: its uniformity. Finally, some options that could be attempted to resist this result are discussed, showing that (strong) truth pluralism and deflationism are affected in different ways

DLEAC and the Rejection Paradox
In this paper we first develop a Dialetheic Logic with Exclusive Assumptions
and Conclusions, DLEAC. We adopt the semantics of the logic of paradox (LP)
extended with a notion of model suitable for DLEAC, and we modify its proof
theory by refining the notions of assumption and conclusion, which are understood
as speech acts. We introduce a new paradox â the rejectability paradox â
first informally, then formally. We then provide its derivation in an extension
of DLEAC contanining the rejectability predicate

Il suolo ci regala tanto. Non calpestiamolo
LIFE + SAM4CP âSoil Administration Model 4 Community Profitâ (www.sam4cp.com), aims to demonstrate that the
planning and regulation of land use require the integration of policies for the protection of soil resources and evaluation the
economic implications, in terms of cost/benefit, their impact on the ecosystemic functions of the resource itself. With effects on the production capacity, availability of raw materials,
biodiversity, carbon cycle, water cycle, landscape heritage and environmental functions of rural areas and the hydrogeological hazards.
The project aims to propose simulation models on the impacts of soil sealing both the consequences, regarding ecosystem and economic, for the community, to be used in the context of urban planning and policies of government land
Land Consumption Monitoring with SAR Data and Multispectral Indices
Land consumption is the increase in artificial land cover, which is a major issue for environmental sustainability. In Italy, the Italian Institute for Environmental Protection and Research (ISPRA) and National System for Environmental Protection (SNPA) have the institutional duty to monitor land consumption yearly, through the photointerpretation of high-resolution images. This study intends to develop a methodology in order to produce maps of land consumption, by the use of the semi-automatic classification of multitemporal images, to reduce the effort of photointerpretation in detecting real changes. The developed methodology uses vegetation indices calculated over time series of images and decision rules. Three variants of the methodology were applied to detect the changes that occurred in Italy between the years 2018 and 2019, and the results were validated using ISPRA official data. The results show that the produced maps include large commission errors, but thanks to the developed methodology, the area to be photointerpreted was reduced to 7300 km2 (2.4% of Italian surface). The third variant of the methodology provided the highest detection of changes: 70.4% of the changes larger than 100 m2 (the pixel size) and over 84.0% of changes above 500 m2. Omissions are mainly related to single pixel changes, while larger changes are detected by at least one pixel in most of the cases. In conclusion, the developed methodology can improve the detection of land consumption, focusing photointerpretation work over selected areas detected automatically
