R3C-GeoResilience. Il plugin open-source per mappare le vulnerabilità territoriali

R3C-GeoResilience è un plugin open-source progettato in ambito QGIS per mappare le vulnerabilità territoriali, tenendo conto di diverse componenti di sensitività, quali: ambiente, infrastrutture, economia, società e patrimonio culturale. Questo plugin offre un’analisi spaziale dettagliata, identificando le aree vulnerabili a diversi tipi di disturbi, sia puntuali che dinamici. Attraverso valutazioni approfondite di queste vulnerabilità, il plugin supporta città e territori nel prepararsi alle incertezze e alle perturbazioni, contribuendo così a rafforzare la resilienza territoriale. Con questo articolo intendiamo presentare la funzionalità del plugin R3C-GeoResilience e la sua potenzialità nel favorire processi condivisi e responsabili verso la resilienza territoriale.

Notes on Spatial Implications of COVID-19. Evidence from Piedmont Region, Italy

The COVID-19 pandemic has been studied by many scholars from a wide range of disciplines. Among these investigations, planners and regional scientists have researched the spatial spread of the contagion. Most of these studies tried to explore the spread of the disease in a fixed period, like annually, and analysed the spatial variables that are most influential on the COVID-19 spread over territories.

A Minimizing Problem of Distances Between Random Variables with Proportional Reversed Hazard Rate Functions

Let X be a random variable with distribution function F and let F_X be the family of proportional reversed hazard rate distribution functions associated to F. Given the random vector (X, Y) with copula C and respective marginal distribution functions F and G ∈ F_X, we obtain sufficient conditions for the existence of G ∈ F_X that minimizes E|X − Y |.

Note on Efron’s Monotonicity Property Under Given Copula Structures

Given a multivariate random vector, Efron's marginal monotonicity (EMM) refers to the stochastic monotonicity of the variables given the value of their sum. Recently, based on the notion of total positivity of the joint density of the vector, Pellerey and Navarro (2021) obtained su cient conditions for EMM when the monotonicity is in terms of the likelihood ratio order. We provide in this paper new su cient conditions based on properties of the marginals and the copula.

On sums of dependent random lifetimes under the time-transformed exponential model

For a given pair of random lifetimes whose dependence is described by a timetransformed exponential model, we provide analytical expressions for the distribution of their sum. These expressions are obtained by using a representation of the joint distribution in terms of bivariate distortions, which is an alternative approach to the classical copula representation.

A Novel Approach for the Assessment of the Nocturnal Image of the Cultural Landscape

Policies aimed at urban and territorial development stressed the importance of landscape as a significant resource for sustainable and economic development. In this perspective, research on landscape visual values and people preferences can support the enhancement of the global values of territories. Currently, the theoretical framework and approaches are mainly limited to the day images of sites, while nighttime landscape is not usually considered.
