Social phenotype extended to communities: expanded multilevel social selection analysis reveals fitness consequences of interspecific interactions.
2014
In social species, fitness consequences are associated with both individual and social phenotypes. Social selection analysis has quantified the contribution of conspecific social traits to individual fitness. There has been no attempt, however, to apply a social selection approach to quantify the fitness implications of heterospecific social phenotypes. Here, we propose a novel social selection based approach integrating the role of all social interactions at the community level. We extended multilevel selection analysis by including a term accounting for the group phenotype of heterospecifics. We analyzed nest activity as a model social trait common to two species, the lesser kestrel (Falc…

Architectural Scenes Reconstruction from Uncalibrated Photos and Map Based Model Knowledge
2001
In this paper we consider the problem of reconstructing architectural scenes from multiple photographs taken from arbitrarily viewpoints. The original contribution of this work is the use of a map as a source of a priori knowledge and geometric constraints in order to obtain in a fast and simple way a detailed model of a scene. We suppose images are uncalibrated and have at least one planar structure as a facade for exploiting the planar homography induced between world plane and image to calculate a first estimation of the projection matrix. Estimations are improved by using correspondences between images and map. We show how these simple constraints can be used to calibrate the cameras, t…
Forage production, N uptake, N2 fixation, and N recovery of berseem clover grown in pure stand and in mixture with annual ryegrass under different ma…
2011
In Mediterranean countries, forage grasses and legumes are commonly grown in mixture because of their ability to increase herbage yield and quality compared with monocrop systems. However, the benefits of intercropping over a monocrop system are not always realized because the efficiency of a grass–legume mixture is strongly affected by agronomic factors. The present study evaluated productivity, N2 fixation, N transfer, and N recovery of berseem clover (Trifolium alexandrinum) grown in pure stand and in mixture with annual ryegrass (Lolium multiflorum) under high or low defoliation frequencies and varying plant arrangements (sowing in the same row or in alternating rows). On average, the b…
Ernesto Rossi e La Riforma Sociale (1926-1930). La carriera interrotta di un economista politico
2022
Con questo saggio si intende ricostruire la breve ma intensa fase di collaborazione di Ernesto Rossi con La Riforma Sociale, prestigiosa rivista di economia e scienze sociali fondata da Francesco Saverio Nitti nel 1894 e diretta da Luigi Einaudi dal 1908. Fra il 1926 e il 1930 Rossi è autore di sette lunghi saggi su tematiche di finanza pubblica, economia applicata e statistica economica che sono stati relativamente trascurati dalla storiografia. La rilettura di questi contributi consente di approfondire alcuni momenti centrali nella sua formazione di economista. In particolare: l’influenza di Einaudi e di De Viti de Marco; la predilezione per un approccio empirico all’analisi economica; la…
A new opportunity for biomagnetic monitoring of particulate pollution in an urban environment using tree branches
2018
Abstract: Environmental magnetism, and the magnetic leaf signal in particular, is amply investigated and applied as proxy for atmospheric particulate matter pollution. In this study, we investigated the magnetic signal of annual segments of tree branches, and the composition of particles deposited hereon. Branches are, contrary to leaves of deciduous trees, available during leaf-off seasons and exposed to air pollution year-round. We examined the intra- and inter-tree variation in saturation isothermal remanent magnetization (SIRM) of branch internodes of London plane (Platanus x aeerifolia Willd.) trees in an urban environment. The branch SIRM, normalized by surface area, ranged from 18 to…
Porti e automazione: spunti in materia di responsabilità delle imprese di sbarco
2019
Lo studio si incentra sull'automazione delle operazioni portuali di imbarco e di sbarco, con particolare riferimento all'incidenza della tecnologia sul sistema di responsabilità degli attori del trasporto marittimo. Sarà trattata la normativa portuale, la governance, il sistema di protezione sociale dei lavoratori portuali e il regime giuridico dei terminal operator. La relazione tra attività totalmente automatizzata e infrastrutture marittime è analizzata nel contesto del diritto internazionale marittimo. The article focuses on the automatization of loading, stowing and unloading ports operations, from the point of view of the impact of the technologies on the system of liabilities of the …
Hospital Reform in Palermo
2023
A partire dal XV secolo, l'ospedale cessa di essere un riflesso della carità cristiana e diventa un veicolo per la gestione del bene comune. In precedenza, la diffusione della spiritualità influenzata dagli Ordini mendicanti aveva stimolato nuove forme di pietà e opere di carità più ampie, tra cui le visite ai malati, la gestione degli ospedali e la distribuzione di cibo e vestiario. Il tardo Medioevo vide un un cambiamento radicale. Gli ospedali divennero centri polifunzionali dedicati a vari tipi di cure. In linea con una tendenza osservata in tutta Europa, le principali città siciliane (Messina, Catania, Palermo, Siracusa e Trapani) adattarono i propri sistemi ospedalieri alle esigenze d…
Il nuovo regime probatorio nei giudizi canonici di nullità del vincolo: riflessioni a prima lettura
2016
The study examines the new rules of evidence arising from the reform of the matrimonial canonical process, intended primarily to enhance the judicial confession and the declarations of the parties, to which can be attribute the force of full proof as long as they are supported by witnesses to the credibility of the parties and unless other elements are present which weaken them. The opinion underlying the essay is that this is a very interesting development, on the basis of which - by the way - the so-called "nullities of conscience" (i.e. the cases in which the invalidity is not demonstrable as such "in foro externo" because it is supported only by the declaration of the interested party) …
Verso un diritto penale geneticamente modificato? A proposito di un recente progetto di riforma dei reati agroalimentari
2016
The article analyses, first of all, – also in a comparative key – the most significant problematic aspects emerging from the resort, very frequent in the food sector, to typification techniques based on references to European legislation. Lexical hybridisms and precautionary needs of the European model of food security risk to affect the classical categories of criminal law, not only at the level of relevant concepts, but also at that of fundamental principles. After an overall look to the contents of the reform Project of agro-food crimes elaborated by the Caselli Commission in 2015, the study focuses particularly on the way the Project suggests to rewrite the cornerstone offence establish…
