Songs in passerine birds are important for territory defense and mating. Speciation rates in oscine passerines are so high, due to cultural evolution, that this bird lineage makes up half of the extant bird species. Leaf warblers are a speciose Old-World passerine family of limited morphological differentiation, so that songs are even more important for species delimitation. We took 16 sonographic traits from song recordings of 80 leaf warbler taxa and correlated them with 15 potentially explanatory variables, pairwise, and in linear models. Based on a well-resolved molecular phylogeny of the same taxa, all pairwise correlations were corrected for relatedness with phylogenetically independe…

Architettura altomedievale nel Santuario di San Michele: analisi stratigrafica degli elevati e studio ricostruttivo 3D
2012
Il Santuario di San Michele a Monte Sant’Angelo (FG) costituisce uno dei più importanti e antichi luoghi della cristianità occidentale. La sede del culto riservato all’Angelo è posta all’interno di una Caverna situata a metà del fianco settentrionale del rilievo montuoso sul cui pianoro si estende il centro abitato. Il contributo riguarda lo studio architettonico, dal rilievo alla lettura stratigrafica muraria fino alla ricostruzione virtuale, del monumento di età longobarda The Sanctuary of San Michele in Monte Sant’Angelo (FG) is one of the most important and ancient places of Western Christianity. The seat of the cult reserved for the Angel is placed inside a Cave located in the middle o…
«Poeni foedifragi, crudelis Hannibal, reliqui iustiores» (off. i 38) Cicerone e gli exempla a proposito delle guerre puniche
2021
In a section of the De officiis, Book i, Cicero deals with the justice of warfare. He asserts that the enemies defeated who were not cruel and savage should be spared, so the maiores utterly destroyed Carthage and Numantia (i 35). In i 38 Cicero refers to the wars undertaken by Romans, distinguishing the ones waged de imperio (as the Punic wars) from the others fighted uter esset (as the wars against Celtiberi and Cimbri): the first must be fought less cruelly, but Cicero justifies the destruction of Carthage with the sentence Poeni foedifragi, crudelis Hannibal, reliqui iustiores, probably containing a quotation from Ennius’s Annales. These passages, examined in comparison with historical …
Metodologia della ricerca sociale e politiche pubbliche
2020
In questo capitolo si passano in rasegna i principali concetti che devono essere padroneggiati dal buon valutatore delle politiche pubbliche e gli strumenti che devono far parte della sua cassetta degli attrezzi. Trattando la causazione e l'esperimento vedremo come nel campo delle scienze sociali sia necessario avvalersi di alcuni accorgimenti per disegnare una buona ricerca valutativa. In this chapter we review the main concepts that must be mastered by the good public policy evaluator and the tools that must be part of his toolbox. In dealing with causation and experiment we will see how in the field of social sciences it is necessary to use some precautions to design good evaluative rese…
Stochastic modeling and prediction of catalytic converters degradation
2009
This paper proposes a stochastic model for describing the degradation process of catalytic converters over time, where the degradation is indirectly measured through the emission of complex hydrocarbons (HC) in legislated driving cycles. The proposed model is the superposition of two processes, the former being a dependent increments process which describes the actual degradation process, and the latter a white noise process which models the experimental errors. In particular, the proposed model assumes that the degradation growth in a small usage interval depends on the degradation level at the beginning of the interval, rather than on the age of the converter. The model has been applied t…
ESTIMATION OF ATTRIBUTE IMPORTANCE BY CHOICE TIME IN A RANKING TASK
2010
The evaluation of the quality of products and services as a function of their attributes has been broadly implemented in marketing research. The current methods for identifying important attributes and prioritize them suffer from theoretical and practical limitations. The former are related to the choice of the most appropriate model for the specific experimental context, the latter are due to the large amount of variables (cognitive, context and survey variables) affecting the chosen model. This work aims at presenting a new method for capturing consumer attribute preferences and estimating the relative importance weights by using the choice time in a ranking task. All is made through an e…
Distributed Consensus in Noncooperative Inventory Games
2009
This paper deals with repeated nonsymmetric congestion games in which the players cannot observe their payoffs at each stage. Examples of applications come from sharing facilities by multiple users. We show that these games present a unique Pareto optimal Nash equilibrium that dominates all other Nash equilibria and consequently it is also the social optimum among all equilibria, as it minimizes the sum of all the players’ costs. We assume that the players adopt a best response strategy. At each stage, they construct their belief concerning others probable behavior, and then, simultaneously make a decision by optimizing their payoff based on their beliefs. Within this context, we provide a …
