Il Paradigma della Città Fluida

2013

Nella recente crisi globale i poderosi flussi di capitali finanziari, sociali e relazionali che hanno alimentato la riqualificazione urbana nel corso degli ultimi quindici anni non sono più disponibili ad essere intercettati in maniera indiscriminata così come è stato possibile fino a qualche anno fa. Nell'era della crisi strutturale le città più dinamiche non sono più quelle in grado di attrarre progetti urbani iconici ed investitori spinti dal mercato immobiliare o dalla redditività delle attività ricreative, ma quelle città che, a partire dalle loro profonde e diversificate risorse culturali, saranno capaci di attuare una vera e propria “metamorfosi” per usarle come base per la creazione…

In current global crisis the strong flows of financial social and relational capitals that powered urban regeneration over the last fifteen years are no longer available to be tapped in an indiscriminate manner as was the case until just a few years ago. The most dynamic cities in the future will no longer be those that are able to attract urban projects and investors driven by the real estate market or leisure-based development but the cities that have deep and different cultural resources and that are able to use them as the basis for creating new urban cultures and for generating new economic values. Revitalising waterfront is no longer easy opportunity for long-term investments or for using the financial capital gains of corporation or hedge funds but a more creative-driven port city has to provide precious opportunities for real development – not only quantitative but more and more qualitative – that is able to produce effects in both the domain of collective assets and that of private capitals.Settore ICAR/21 - Urbanistica

Molte Palermo. Temi

2019

Nel tema delle incompiute idee di città possibili si riconoscerà il paradigma connotativo dello stesso divenire di Palermo, lungo un percorso millenario di processi di trasformazione nessuno dei quali portato a compimento, in virtù di quel valore distintivo di exemplum che non necessita di ulteriori e conclusive dimostrazioni. Il corso della storia, del resto, ha imposto a Palermo il ciclico riproporsi di destini interrotti. Tale si rilevò l’invenzione della città capitale, quella della “quadratura geometrica e della croce di strade” sovrimpressa a quella archetipica e fondativa della Pan-ormos scambiatrice. E l’incompiutezza sarà il tratto distintivo della città dei rettifili stradali otto…

In the theme of unfinished ideas of possible cities will recognize the connotative paradigm of the evolution of Palermo will be recognised along a thousand year path of transformational processes none of which was completed by virtue of the distinctive value of exemplum that does not require additional and conclusive demonstrations. The course of history has moreover imposed on Palermo a cyclical recurrence of broken destinies. This was evidence of the invention of the capital city that of the “geometric square and the cross roads” superimposed on the archetypal underpinning of Pan-ormos as a place of exchange. And incompleteness will be the hallmark of the city of the nineteenth century straight roads heading towards undefined destinations the symptomatic expression of the idea of a preordained effect of suspension. Similarly unfinished will be the Palermo of the redevelopment plans in the nineteenth and twentieth centuries upto the shapeless development of the contemporary city and the new arterial routes (the Circonvallazione) manifestations of further “Palermo as abstraction” ever more distant from “Palermo as places”. A city ultimately characterized by continuous metamorphoses replacement of values absorptions oblivion and cultural desecration. From this distance one can indeed observe Palermo from a marginal and peripherical point of view as regards its urban limits opening up a different prospect penetrating and maybe even superior able to understand facts and phenomena in depth.Settore ICAR/14 - Composizione Architettonica E Urbana

The Inclusion of Socially Irresponsible Companies in Sustainable Stock Indices

2019

Social rating agencies implement complex filters to identify the companies with the best sustainable and social performance and help investors select the companies for their sustainable portfolios. This study analysed whether companies that are defined as ethical, sustainable and socially responsible by those agencies actually deserve this label. More specifically, the inclusion in the prestigious Dow Jones Sustainability Index (DJSI) World of companies that have been involved in controversies according to the Thomson Reuters Eikon database was studied. The results show that the inclusion of irresponsible companies in the DJSI Index is a fact. This outcome is in line with previous studies t…

On the duration of sovereign ratings cycle phases

2021

Abstract Using long-term sovereign ratings data for a panel of 130 countries over the last three decades, we investigate the duration and determinants of sovereign rating phases through the lens of discrete-time Weibull models. We find that the likelihood of the end of the ‘speculative-grade’ phase increases as time goes by (i.e. there is positive duration dependence), but the ‘investment-grade’ phase is not duration dependent. Thus, for sovereigns rated as speculative, the build-up of reputation as good borrowers is a gradual process, whereas the reputation of investment-grade sovereigns solidifies and remains unchanged as time passes. However, the length of both phases significantly depen…

GekkoFS — A Temporary Burst Buffer File System for HPC Applications

2020

Many scientific fields increasingly use high-performance computing (HPC) to process and analyze massive amounts of experimental data while storage systems in today’s HPC environments have to cope with new access patterns. These patterns include many metadata operations, small I/O requests, or randomized file I/O, while general-purpose parallel file systems have been optimized for sequential shared access to large files. Burst buffer file systems create a separate file system that applications can use to store temporary data. They aggregate node-local storage available within the compute nodes or use dedicated SSD clusters and offer a peak bandwidth higher than that of the backend parallel f…

Generating harmonic surfaces for interactive design

2014

Abstract A method is given for generating harmonic tensor product Bezier surfaces and the explicit expression of each point in the control net is provided as a linear combination of prescribed boundary control points. The matrix of scalar coefficients of these combinations works like a mould for harmonic surfaces. Thus, real-time manipulation of the resulting surfaces subject to modification of prescribed information is possible.

Abnormalities in serum concentrations of interleukin-2, interferon-alpha and interferon-gamma in schizophrenia not detected.

1992

The hypothesis of an immunological defect in schizophrenia has been supported by reports on abnormal production of interleukin-2 (IL-2) and interferons (IFNs) in schizophrenic patients. In the present study we determined the serum concentrations of IL-2, IFN-alpha and IFN-gamma in 10 first onset, neuroleptic-naive schizophrenics, in 6 pretreated patients who were drug free (1 week to 2 years) at the time of the investigation and in 15 matched healthy controls. No IFN-alpha was detected in schizophrenics' and in control sera. No differences were found in IL-2 and IFN-gamma levels between schizophrenics and controls. Thus the present study failed to support the hypothesis of an immunological …
