Predictive mechanistic bioenergetics to model habitat suitability of shellfish culture in coastal lakes

2014

Quantitative tools based on mechanistic modelling of functional traits able to enhance the sustainability of aquaculture and most other human activities (i.e. reducing the likelihood of detrimental impacts optimising productions), are especially important factors in the decision to site aquaculture facilities in coastal lakes, ponds and lagoons and, in the case of detrimental impact, to adopt mitigation measures. We tested the ability of mechanistic functional trait based models to predict life history traits of cultivable shellfish in shallow coastal lakes. Dynamic Energy Budget (DEB) models were run to generate spatially explicit predictions of Mytilus galloprovincialis life history (LH) …

Growth and reproductive simulation of candidate shellfish species at fish cages in the Southern Mediterranean: Dynamic Energy Budget (DEB) modelling …

2012

Abstract A Dynamic Energy Budget (DEB) model is used to simulate growth and reproduction of the shellfish Mytilus galloprovincialis and Crassostrea gigas in an integrated multi-trophic aquaculture (IMTA) farm scenario situated in the Southern Mediterranean (the Gulf of Castellammare, Sicily). We modelled the effect of primary production enrichment at fish cages on shellfish growth and life history traits using 4 years-hourly temperature data (01 January 2006–31 December 2009) at a depth of 1 m. Outputs of the DEB simulations were: the maximum theoretical total shell length of shellfish, the potential reproductive outputs and the mean annual von Bertalanffy growth rate. There was a mean incr…

Mussels as a model system for integrative ecomechanics.

2015

Copyright © 2015 by Annual Reviews. All rights reserved. Mussels form dense aggregations that dominate temperate rocky shores, and they are key aquaculture species worldwide. Coastal environments are dynamic across a broad range of spatial and temporal scales, and their changing abiotic conditions affect mussel populations in a variety of ways, including altering their investments in structures, physiological processes, growth, and reproduction. Here, we describe four categories of ecomechanical models (biochemical, mechanical, energetic, and population) that we have developed to describe specific aspects of mussel biology, ranging from byssal attachment to energetics, population growth, an…

Thinking beyond organism energy use: a trait-based bioenergetic mechanistic approach for predictions of life history traits in marine organisms

2014

The functional trait-based bioenergetic approach is emergent in many ecological spectra, from the conservation of natural resources to mitigation and adaptation strategies in a global climate change context. Such an approach relies on being able to exploit mechanistic rules to connect environmental human-induced variability to functional traits (i.e. all those specific traits defining species in terms of their ecological roles) and use these to provide estimates of species life history traits (LH; e.g. body size, fecundity per life span, number of reproductive events). LHs are species-specific and proximate determinants of population characteristics in a certain habitat. They represent the …

THE NEW ARCHITECTURE OF THE EUROPEAN ECONOMIC GOVERNANCE AND ITS CONSTITUTIONAL IMPLICATIONS AT THE EU AND NATIONAL LEVEL

La tesi analizza la nuova architettura costituzionale della governance economica europea come ridefinita dalle più recenti riforme europee predisposte al fine di contrastare la crisi economico-finanziaria dell’area euro e il suo impatto sull’assetto costituzionale dell’Unione europea e degli Stati Membri. La tesi, articolata in quattro capitoli e redatta interamente in lingua inglese, ripercorre le tappe salienti dell’evoluzione dell’Unione Economica e Monetaria, analizza le principali disposizioni della “costituzione economica” dell’Unione europea e contiene un’esposizione, in chiave critica, delle principali misure adottate dall’Unione europea per contrastare la crisi economica della zona…

The Introduction of the “Balanced Budget” Principle into the Italian Constitution: What Perspectives for the Financial Autonomy of Regional and Local…

2013

This paper analyses the impact on regional and local authorities of Articles 117 and 119 of the Italian Constitution as amended by Constitutional Law no. 1/2012. In particular, it attempts to verify whether the new formulation of these constitutional provisions materializes the risk of a significant reduction in the financial autonomy of both Regions and Local Governments. With the constitutional reform the legislative competence of “harmonization of public account” has become an exclusive State competence, the “balanced budget” principle has been extended to Regions and local authorities and public borrowing has been broadly prohibited. What is the actual significance of the changes introd…

I più recenti sviluppi costituzionali del ciclo di bilancio

2023

The A. answer to a series of questions by the Director of the "Gruppo di Pisa" Journal. The questions concern the parliamentary procedure followed to enact the State Budget Law for the year 2023 (law No 197/2022). The A. debates over: the possibility to prove the evident violation of parliamentary privileges in the procedure followed by the two chambers of the Italian parliament (Const. court. orders Nos. 17/2019 and 60/2020); the impact of Next Generation EU and of NPRR over the National Budgetary procedures; the role played by the Budget Parliamentary Office (UPB) and by the State General Accounting Office in parliamentary procedures concerning the State Budget Law for the year 2023

Lo sviluppo e l’innovazione

2021

Le norme della legge di bilancio per il 2021 in materia di sviluppo e innovazione sembrano ancora legate a una logica di natura emergenziale, ponendosi in continuitàconle normative adottate nel corso del 2020 per fare fronte alle fasi più acute della crisi causata dal Covid-19, con le quali, non a caso, condividono il carattere temporaneo degli interventi. Questi si basano su incentivi ai consumi, garanzie pubbliche sui prestiti bancari e varie provvidenze da distribuire tramite fondi pubblici appositamente istituiti. Sorprende l’assenza di progetti ambiziosi per lo sviluppo economico, che avrebbero potuto essere coordinati, o costituire anticipazioni, di quelli da inserire successivamente …

Una valutazione economica completa della vaccinazione estensiva contro i rotavirus con il vaccino RIX4414 a livello nazionale e regionale in Italia

2013

Background. Vaccination of all healthy children against rotavirus (RV) has been recommended, since the availability of vaccines, both in Europe (PIDJ) and Italy (pediatricians). The aims of universal vaccination against RV include the protection of children against moderate/severe gastroenteritis forms by RV (GARV), prevent hospitalizations, reduce the severity and duration of the disease, and reduce morbidity and socio- economic costs. Payers need to informed regarding the efficacy and the healthcare utilization related to RV vaccination in order to decide in favour of its extensive implementation. The aim of this paper is to assess the clinical and financial impact of the extensive vaccin…

Scritti in onore di Pellegrino Capaldo

2014

La qualità dei servizi è stata riconosciuta come un rilevante aspetto caratterizzante la performance dell’azienda pubblica, analogamente alla capacità di operare secondo criteri di efficienza e nel rispetto dei vincoli di bilancio. Sebbene sia possibile riscontrare alcuni significativi casi di adozione di politiche di customer satisfaction nelle amministrazioni pubbliche italiane, a tutt’oggi il tema presenta significative criticità, specialmente in ordine agli aspetti metodologici e agli strumenti operativi che consentano di integrare dette politiche nel sistema di programmazione e controllo delle aziende che erogano tali servizi. Il presente lavoro adotta una diversa prospettiva di analis…
