The causal effect of crop diversification obligations on crop diversity: An EU-level analysis
No full textThe Common Agricultural Policy (CAP) is a cornerstone policy of the European Union, increasingly focused on promoting environmentally sustainable practices. In 2014, the CAP introduced Greening payments and a crop diversification requirement to enhance soil resilience and mitigate ecosystem degradation. Despite its economic significance, the policy's effectiveness across the EU remains largely limited. This study evaluates the impact of the Greening crop diversification requirement on crop diversity itself and on a set of subsequent outcomes, including agricultural land allocation, the economic performance of farms and indirect environmental outcomes. Using farm-level data from the Farm Accountancy Data Network (2012–2017), causal relationships are identified, through a design that combines propensity score matching and difference-in-differences, by comparing farms needing to adapt to the new requirements to those who were already compliant. Additionally, a regression discontinuity design estimates local average treatment effects for 2017, thereby exploiting the diversification requirement's threshold-based design. Both strategies corroborate the conclusion that Greening measures have significantly increased crop diversity across the EU, impacting over the subset of farms that were not already compliant with regulation requirements, primary small- and medium-size crop farms; moreover, results for the remaining farm-level outcomes are consistent with adaptation responses to the new environmental requirements. Overall, the results highlight the policy's effectiveness in promoting sustainable agriculture throughout the EU
Advanced methodologies of valorization of catalytically active automotive waste for remediation of landfill leachates and organic synthesis
Full text linkWaste produced annually worldwide has been increasing in the last decades due to the development of industrialization and the continuous growth of consumption. Within the sole European Union, 2.1 billion tons of waste are ended every year in landfills and such an excessive waste production increasingly impacts on environmental and human well-being as well as on the economic resources required for waste management.
Due to the impossibility to eliminate the production of waste, the most profitable strategy to face issues related to its management consists in the development of sustainable approaches of waste revalorization in accordance with the principles of Circular Economy. Hence, reuse and recycling should be prioritized over the commoner option of disposal in landfill. Individual and collective actions to control and differentiate waste have been already adopted but they must be more and more implemented.
This PhD project aims to develop an innovative and eco-friendly methodology to reduce the degree of pollution of landfill leachate concentrates expressed as the Chemical Oxygen Demand (COD) necessary to oxidize organic and inorganic pollutants present in 1 liter of leachate.
The investigated novel strategy for reduction of COD values avails of supported and recyclable catalysts derived from spent Scrap Waste Automotive Converters (SCATs,) recovered and regenerated from end-of-life vehicles (ELVs).
SCATs have been proven to act as efficient supported transition metal-based catalysts non only in oxidation reactions of landfill leachates but also, more in general, in organic synthesis. Indeed, this PhD research work provides the proof of principle that SCATs from ELVs can actually be promising catalysts for carbon-carbon bond forming eco-friendly cross-coupling processes, such as the Suzuki Miyaura cross-coupling of a series aryl halides with aryl boronic acids herein systematically investigated as the model reaction. This study paves the way to a new life of catalytic waste in Green Chemistry
Contamination of Wheat Flour and Processed Foodstuffs with Soybean and Mustard Allergenic Proteins
No full textIn recent years, sustainable agricultural practices in wheat cultivation have garnered significant attention, particularly those focused on minimizing pesticide and herbicide usage to safeguard the environment. One effective approach is green manuring, which entails rotating wheat with crops such as soybean and mustard to harness their natural pesticidal and herbicidal properties. While this method presents clear environmental advantages, it also poses a risk of cross-contamination, as these globally recognized allergens may unintentionally pass through wheat-based products. To protect consumers with allergies, there is an urgent need for a reliable analytical method to detect and quantify these allergenic proteins in wheat-derived foodstuffs. In this study, we assessed various protein extraction protocols to optimize the recovery of soybean and mustard allergens from wheat flour. The extracted proteins were analyzed using a bottom-up proteomics approach involving trypsin digestion, coupled with reversed-phase liquid chromatography and mass spectrometry in multiple reaction monitoring (MRM) mode. Two key allergenic proteins, Glycinin G1 and 11S Globulin, were selected as representative for soybean and mustard, respectively. The identified quantifier marker of Glycinin G1 was VLIVPQNFVVAAR (m/z 713.4312+), while FYLAGNQEQEFLK (m/z 793.8962+) and VFDGELQEGR (m/z 575.2802+) were designated as qualifier markers. The selection of specific marker peptides for mustard proved challenging due to the high structural similarity among proteins from Sinapis alba and other members of the Brassicaceae family. For 11S Globulin, FNTLETTLTR (m/z 598.3192+) was recognized as the quantifier marker, with VTSVNSYTLPILQYIR (m/z 934.0192+) serving as the qualifier marker. The developed method underwent thorough validation for linearity, limit of detection (LOD), limit of quantification (LOQ), recovery, repeatability, and reproducibility, as well as potential matrix and processing effects. This strategy successfully facilitated the identification and quantification of soybean and mustard allergenic proteins in complex, processed food matrices, including naturally contaminated flour and cookies. These findings enhance food safety monitoring and regulatory compliance, thereby helping to mitigate allergen-related risks in wheat-based products
¿MÁS ALLÁ DE LOS DERECHOS HUMANOS? LOS DERECHOS FUNDAMENTALES ENTRE JUSTICIA, VALIDEZ Y EFICACIA
No full textSyntagma “human rights” has given way in post-metaphysical and secularized society to the phrase “fundamental rights”. The research examines three theories of fundamental rights formulated by Michel Troper, Gregorio Peces-Barba Martínez and Luigi Ferrajoli, to verify the possibility of eliminating within the theoretical horizon of fundamental rights the underlying (transcendental) reference to humanum

"React", "Command", or "Instruct"? Teachers' Mental Models on End-User Development
No full textThis paper presents fndings from a thinking-aloud protocol exploring mental models in 28 elementary school math teachers during their initial attempt at composing and testing trigger-action rules for a smart tangible educational device. In the study, two sets of event-driven primitives were implemented in an End-User Development platform for guiding teachers with no programming experience in defning new functions of the device: "concrete", based on actual actions performed on the device, and "abstract", based on general defnitions of events/actions. With a thematic analysis, we identifed three diferent metaphors that drive participants interaction with the device. We discuss how the metaphors infuenced performance and how the order of exposition to the two primitive sets impacted their grasping of the trigger-action logic. Our fndings suggest the importance of guiding teachers in assuming efective metaphors for performing End-User Development tasks, to empower them to adopt an active role toward digital devices in education
State, Territori, Colonized
No full textThe territory is the place of a political category of
sovereignty, the definition of a specific and cultural legitimacy that can become a memory of history itself. It is a representation that disappears with man himself or with the
very men who had maintained it, but which – and this is
precisely where that specific force of change lies – lives again
as a necessity of law and politics, which have their roots in
the possibility of representing themselves as sovereigns. The
risk of a return of imperialism in different forms, such as
those of the great international organizations, remains ever
closer

Reuse of UHT Milk Close to Expiring and Almond Okara in the Production of Fresh Cheese
No full textThis study evaluated the possibility of recycling ultra-high temperature (UHT) milk close to the expiry date in the production of fresh cheese fortified with almond okara, a by-product of almond-based beverage production. The experimental design involved the addition of okara to skimmed and semi-skimmed milk at two different levels of concentration (25% and 50%), obtaining cheese prototypes coded as CS-1/CS-2 and CP-1/CP-2, respectively. The chemical characterization of okara showed a high fiber (13.47 g/100 g) and fat content (18.62 g/100 g), with 90% of lipids composed of polyunsaturated fatty acids (PUFAs). The physicochemical properties and safety of the cheese samples during 30 days of storage were evaluated. Fortification allowed the cheeses to reach the minimum levels for the nutritional claims "source of fiber" (3 g/100 g), "rich in fiber" (6 g/100 g), and "rich in unsaturated fatty acids" (40% of total fats). The addition of okara at 50% level made the cheeses more consistent, with pleasant almond flavor but increased lipid oxidation, even though the oxidative test gave values that did not exceed the limits threshold of toxicological concern (30 mu g/kg body weight/day). In addition, the samples obtained with skimmed milk (CS, CS-1, and CS-2) were found to be more consistent and with higher yellow index values than the corresponding formulations obtained with semi-skimmed milk. During storage, all samples showed a reduction in consistency and hardness and an increase in astringent and vegetal flavor, especially for samples containing 50% okara. At the end of the storage period, all cheeses were microbiologically safe
