‘Landscape of exception’: Power inequalities and ethical planning challenges in the landscape transformation of south-eastern Sicily
2021
In some marginal contexts of Southern Italy, in light of specific economic, political and social conditions, certain relationships between ‘strong powers’ and ‘weak powers’ produce a suspension of norms/rights that is, paradoxically, ‘normalised’. This creates a particular spatial variation of Agamben’s (2005) state of exception concept: the ‘landscape of exception’. With respect to the possible conditions of ‘exception’, this article describes the ‘landscape of exception’ of the greenhouse system in South-Eastern Sicily. This ‘landscape of exception’ is generated by the greenhouses, in particular those dedicated to vegetable production, through an effective mechanism of spatial manipulati…
Think transformational leadership – Think female?
2015
This study examines whether the behaviors of transformational, transactional, and laissez-faire leadership are perceived as being more typical of female or male leaders. In a questionnaire study, 113 participants in Germany were asked to rate the probability of occurrence of a specific leadership behavior for male and female leaders, respectively. A diagnostic ratio for each leadership behavior allows the determination of the direction and degree of gender-specific evaluations. As predicted, transformational leadership is believed to be more typical of female leaders. Nevertheless, inspirational motivation and idealized influence attributed are rated as being gender neutral. For transactio…
Non-Hermitian Physics and Master Equations
2022
A longstanding tool to characterize the evolution of open Markovian quantum systems is the GKSL (Gorini-Kossakowski-Sudarshan-Lindblad) master equation. However, in some cases, open quantum systems can be effectively described with non-Hermitian Hamiltonians, which have attracted great interest in the last twenty years due to a number of unconventional properties, such as the appearance of exceptional points. Here, we present a short review of these two different approaches aiming in particular to highlight their relation and illustrate different ways of connecting non-Hermitian Hamiltonian to a GKSL master equation for the full density matrix.
La cultura ci salverà? Processi di touristification a base culturale nel centro storico di Palermo
2023
Negli ultimi tre decenni la cultura ha avuto un ruolo chiave nella costruzione delle politiche urbane, divenendo uno strumento decisivo nella definizione delle strategie di sviluppo economico e nell’accesso alla competizione globale che caratterizzano l’attuale regime di neoliberismo urbano (Miles e Paddison 2005). Anche nel sud Europa la cosiddetta rigenerazione a base culturale ha rappresentato e continua ancora oggi a rappresentare una vera e propria ortodossia urbana, che trova nel turismo tanto una ragione di esistenza quanto un campo di attuazione. In particolare, negli ultimi anni i centri storici di molte città sudeuropee sono stati oggetto di trasformazioni profonde in cui pratiche…

Optical force rectifiers based on PT-symmetric metasurfaces
2018
We introduce here the concept of optical force rectifier based on parity-time symmetric metasurfaces. Directly linked to the properties of non-Hermitian systems engineered by balanced loss and gain constituents, we show that light can exert asymmetric pulling or pushing forces on metasurfaces depending on the direction of the impinging light. This generates a complete force rectification in the vicinity of the exceptional point. Our findings have the potential to spark the design of applications in optical manipulation where the forces, strictly speaking, act unidirectionally. R.A. and B.G. would like to acknowledge financial support from the Max Planck Society. J.C. acknowledges the suppor…
Parte III. Cap. IX. I Fattori della produzione agricola.
2021
The process of modernization and innovation in the agricultural sector requires careful analysis regarding financial resources and the need to strengthen economic structures within it. The specific discipline of agricultural credit is different from that provided for other productive activities. The "naturalness" of the agricultural product is reflected in the incidence of credit risk. These economic evaluations, which are at the basis of what is known as agricultural exceptionalism, have repercussions on the legal system of access to credit, requiring, for example, a differentiated system of evaluation of creditworthiness.
