Bright spots as climate‐smart marine spatial planning tools for conservation and blue growth
2021
Marine spatial planning that addresses ocean climate-driven change (‘climate-smart MSP’) is a global aspiration to support economic growth, food security and ecosystem sustainability. Ocean climate change (‘CC’) modelling may become a key decision-support tool for MSP, but traditional modelling analysis and communication challenges prevent their broad uptake. We employed MSP-specific ocean climate modelling analyses to inform a real-life MSP process; addressing how nature conservation and fisheries could be adapted to CC. We found that the currently planned distribution of these activities may become unsustainable during the policy's implementation due to CC, leading to a shortfall in its s…
Polyculture as a tool to increase the economic income: a study case in the Gulf of Castellammare
2010
Polyculture is a practice involving integration between organisms of different trophic levels (i.e. fish with low-trophic-level organism like molluscs and/or algae). This paper, reporting on a field experiment carried out during 2004 in the Gulf of Castellammare (South Tyrrhenian), showed that mussels transplanted in areas under fish farm influence grew up better than mussels transplanted far from fish farm. Thus, results pointed out polyculture as a reliable tool for i) increasing local bivalve production, ii) obtaining the reduction of importation from other countries and iii) increasing the environmental sustainability of fish aquaculture.
La Rocca di Cefalù: modello geomeccanico e condizioni di rischio per la cittadina normanna
2021
La cittadina di Cefalù, ubicata a circa 70 km da Palermo, è una delle perle del Mediterraneo, per la bellezza dei luoghi, dominati dalla Rocca, imponente rupe carbonatica alta circa 250 m s.l.m., e per i beni architettonici (Figg. 1 e 2). Fondata dai greci con il nome di Κεφαλοίδιον tra il XIV e il XIII a.C., conserva sulla Rocca il palazzo santuario ciclopico-megalitico, noto come Tempio di Diana. Sul ciglio della Rocca e per il suo intero sviluppo si snoda la cinta muraria di tipo megalitico risalente alla fine del V secolo a.C. (periodo pre-ellenico), in parte ricostruita nel periodo bizantino (VII÷IX secolo d.C.). Nel periodo normanno (secolo XII d.C.) furono costruiti i principali monu…
Stato dell’arte degli interventi sulla sorgente per la mitigazione delle vibrazioni generate da sistemi di trasporto su ferro
2008
La crescente esigenza di mobilità registrata negli ultimi anni in molte città italiane ha condotto all’elaborazione di importanti progetti per la realizzazione, o l’ampliamento, di reti di trasporto di massa in ambito urbano. In molti casi le scelte progettuali prevedono la realizzazione di infrastrutture su ferro, come tram, metropolitana, o ferrovia urbana. Tuttavia, soprattutto nelle città caratterizzate da importanti patrimoni edilizi storici, la realizzazione di tali tipologie infrastrutturali comporta enormi problemi di inserimento ambientale dovuti agli impatti acustici e vibrazionali prodotti dall’esercizio dei vettori. Un caso emblematico che ha mobilitato l’attenzione pubblica, na…

Soluzioni basate sulla natura per le città portuali. L’approccio “Building with nature” e i limiti di trasferibilità nel contesto italiano
2022
Achieving sustainable development goals in port cities is an increasingly challenging task as the trend is toward their expansion for global competition, thus increasing their impacts on soil, atmosphere, water, and marine and terrestrial ecosystems. The present contribution proposes to explore the Building with Nature approach developed by EcoShape and Deltares in the Dutch context through the comparison of case studies and to highlight some critical issues in its transferability to the Italian context.
Coexistence between IEEE802.15.4 and IEEE802.11 through cross-technology signaling
2017
When different technologies use the same frequency bands in close proximity, the resulting interference typically results in performance degradation. Coexistence methods exist, but these are often technology specific and requiring technology specific interference detection methods. To remove the root cause of the performance degradation, devices should be able to negotiate medium access even when using different technologies. To this end, this paper proposes an architecture that allows crosstechnology medium access by means of a Time Division Multiple Access (TDMA) scheme. In order to achieve cross-technology synchronization, which is required for the TDMA solution, an energy pattern beacon…

Pincìpi e naufragi: alcune critiche alla nuova filosofia per il diritto internazionale di Ronald Dworkin e il caso emblematico delle politiche in att…
2022
This contribution critically analyzes Ronald Dworkin's New Philosophy for International Law, by underlying how, his theory of law as interpretation, if transposed to the level of the relations between states, more clearly shows some weaknesses which are mainly connected with the ideality of its fundamental assumptions. After having introduced the fundamental aspects of Dworkin's reflection on international law, the specific contents of the particular principles - of mitigation and salience - that Dworkin places at the basis of his vision of international law are critically analyzed in the face of the prerogatives of contemporary national sovereignty and in relation to the structural limits …
