Biodiversità in alcune specie del genere Mentha nel territorio dei Monti Nebrodi (Sicilia N-W).
2008
In Nebrodi Mountains (N-E Sicily), the genus Mentha is represented by an high number of species, in many cases typical of humid and subhumid environments. This work was addressed to investigate about the biomorphological traits of various accessions belonging to 3 Mentha species collected in the Nebrodi highlands, namely 22 accessions of Mentha spicata, 12 of Mentha suaveolens and 13 of Mentha aquatica. Plant material was picked up starting from the early spring 2007, from different sites as in altitude and in pedological and climatic traits, that were distributed over an area of 200.000 ha approx.. Later on, all collected plant individuals were transplanted in a collection field, appositel…
A 'gateway city' between landscape and cultural heritage
2015
The paper analyzes the achievable strategic role that the porto of Porto Empedocle (sinergy by Agrigento, its "city mother") could have. This marginal city, localized in the center of the African side of the Sicily, is far from European politics, but this situation could change. It's necessary to improve the sea routes and to activate the disused railway line from Porto Empedocle to Castelvetrano (near Trapani). This solution will help the accessibility of Agrigento and the development of the little coastal towns organized in a slow and sustainable network. Lo scritto analizza il possibile ruolo strategico che il porto di Porto Empedocle (in sinergica con la sua città-madre, Agrigento). Que…
Phrasal prosody constrains word segmentation in French 16-month-olds
2011
Infants who are in the process of acquiring their mother tongue have to find a way of segmenting the continuous speech stream into word-sized units. We present an experiment showing that French 16-month-olds are able to exploit phonological phrase boundaries in order to constrain lexical access. Using the conditioned head-turning technique, we showed that infants trained to turn their head for a bisyllabic word responded more often to sentences that contained this word, than to sentences that contained both syllables of this word separated by a phonological phrase boundary. We compare these results with similar results obtained with English-speaking infants, and discuss their implication fo…

The Political Economy of the World Bank. The Early Years
2009
This book covers the early years of the International Bank of Reconstruction and Development (IBRD), commonly known as the World Bank when it first confronted the issue of development as a fundamental part of its mission. The book is mainly concerned with how the Bank interpreted its mission and, more specifically, how its mission was born: what events shaped it, what cultural and ideological background influenced it and what was the historical context in which it arose. So this book is a contribution to the study of the prehistory of development, understood in its social and economic context. In this respect, the study of the early years of the World Bank offers excellent context for obser…
Biodiversità e caratteristiche bio-agronomiche in lenticchia (lens culinaris medik.).
2016
Tra le leguminose da granella la lenticchia (Lens culinaris Medik.), occupa un posto importante nella alimentazione umana, per la quantità e qualità di proteine contenute nel seme e per il contenuto di carboidrati associati alla bassa presenza di sostanze antinutrizionali. La coltivazione della lenticchia è ancora basata, nella maggior parte del mondo, su ecotipi locali e solo in pochi Paesi, come il Canada, si utilizzano varietà selezionate. La coltura, come molte leguminose minori, risulta poco presente negli ordinamenti colturali italiani e, negli ultimi decenni, la superficiecoltivata ha registrato una notevole riduzione a causa di ,molteplici fattori, come mancanza di germoplasma selez…
Behavioral profile of intermittent vs continuous access to a high fat diet during adolescence
2018
Abstract Over the past few years, the effects of a high-fat diet (HFD) on cognitive functions have been broadly studied as a model of obesity, although no studies have evaluated whether these effects are maintained after the cessation of this diet. In addition, the behavioral effects of having a limited access to an HFD (binge-eating pattern) are mostly unknown, although they dramatically increase the vulnerability to drug use in contrast to having continuous access. Thus, the aim of the present study was to compare the effects of an intermittent versus a continuous exposure to an HFD during adolescence on cognition and anxiety-like behaviors, as well as to study the changes observed after …
Letter-case information and the identification of brand names.
2014
A central tenet of most current models of visual-word recognition is that lexical units are activated on the basis of case-invariant abstract letter representations. Here, we examined this assumption by using a unique type of words: brand names. The rationale of the experiments is that brand names are archetypically printed either in lowercase (e.g., adidas) or uppercase (e.g., IKEA). This allows us to present the brand names in their standard or non-standard case configuration (e.g., adidas, IKEA vs. ADIDAS, ikea, respectively). We conducted two experiments with a brand-decision task (‘is it a brand name?’): a single-presentation experiment and a masked priming experiment. Results in the s…
The role of the frequency of constituents in compound words: evidence from Basque and Spanish.
2008
Recent data from compound word processing suggests that compounds are recognized via their constituent lexemes (Juhasz, Starr, Inhoff, & Placke, 2003). The present lexical decision experiment manipulated orthogonally the frequency of the constituents of compound words in two languages: Basque and Spanish. Basque and Spanish diverge widely in their morphological properties and in the number of existing compound words. Furthermore, the head lexeme (i.e., the most meaningful lexeme related to the whole-word meaning) in Spanish tends to be the second lexeme, whereas in Basque the percentage is more distributed. Results showed a facilitative effect of the frequency of the second lexeme, in both …
Optimal Control of Dissipative Quantum Systems
2008
We study the control of finite dimensional quantum systems by external laser fields. After examining the concrete example of the diatomic molecular alignment in dissipative media, we are interested in the problem of optimal control, where the objective is to bring the system from an initial state into a given final state while minimizing a cost functional. The Pontryagin maximum principle (PMP) provides necessary conditions for optimality, by establishing that any optimal trajectory is the extremal solution of an extended problem of Hamiltonian structure. In this context, we perform the analysis of two particular systems. The first one is a dissipative 2-level system, for which we determine…
