Fire risk sub-module assessment under solvency II. Calculating the highest risk exposure

2021

The European Directive 2009/138 of Solvency II requires adopting a new approach based on risk, applying a standard formula as a market proxy in which the risk profile of insurers is fundamental. This study focuses on the fire risk sub-module, framed within the man-made catastrophe risk module, for which the regulations require the calculation of the highest concentration of risks that make up the portfolio of an insurance company within a radius of 200 m. However, the regulations do not indicate a specific methodology. This study proposes a procedure consisting of calculating the cluster with the highest risk and identifying this on a map. The results can be applied immediately by any insur…

Decoherence in a fermion environment: Non-Markovianity and Orthogonality Catastrophe

2013

We analyze the non-Markovian character of the dynamics of an open two-level atom interacting with a gas of ultra-cold fermions. In particular, we discuss the connection between the phenomena of orthogonality catastrophe and Fermi edge singularity occurring in such a kind of environment and the memory-keeping effects which are displayed in the time evolution of the open system.

La “naturalización” mediática de las catástrofes: una aproximación crítica

2010

La informacion sobre las llamadas catastrofes naturales que transmiten los medios de comunicacion suele construirse de forma acritica, incidiendo en la casualidad, imprevisibilidad e imposibilidad de luchar contra fenomenos naturales de semejante magnitud. Se conforman asi discursos fundamentados en la naturalizacion, que eluden profundizar en la responsabilidad de determinados agentes politicos, economicos, sociales y culturales. Para fundamentar la critica a dicha naturalizacion se recurre, en este trabajo, al termino y concepto de Responsabilidad Comunicativa, segun el cual los duenos de los medios, los procesos de produccion y los productos mediaticos deben actuar de acuerdo con una log…

W pogoni za sensacją : kulturowy wymiar mrocznej turystyki (dark tourism)

2018

Wychodząc z założenia, że wszelkie katastrofy, zarówno przyrodnicze, jak i spowodowane przez człowieka, mają kulturowy wymiar, w artykule skoncentrowałam się nie na samych miejscach tragicznych naznaczonych śmiercią i krwią, ale na kształtowaniu się wyobrażeń związanych z tymi miejscami w efekcie kontaktu z nimi turystów. Śledzę zatem proces mityzacji, a nawet sakralizacji „czarnych miejsc” (black spots), funkcjonowania wyobrażeń na temat katastrofy (w Czarnobylu czy w Smoleńsku), które determinują wszystkie następne zachowania wobec kolejnych katastrof. Zwracam uwagę na źródła popularności mrocznej turystyki (dark tourism) oraz kreowania przez media potrzeby przeżywania mocnych wrażeń. Wsp…

The shape of the water

2016

The Po River is a living organism that breathes: it inhales and swells; it exhales and releases its energy. Between two extreme phases of overflow and shallows, there are endless variations. In Piacenza, at the riverside, hydrometric instruments also took size and shape of a special building in reinforced concrete crowned by conical elements. When the water level rises, it floods the earth gradually; it deletes some marks lapping, and then reveals other things. The water clears and continuously constructs, in a surreal atmosphere of expectation, always in the balance between the catastrophe and the regeneration of a soil that emerges like an archaeological plan. Visible volumes are like the…

Model społeczeństwa a założenia Specjalnej Strefy Demograficznej

2016

Założenia opolskiej Specjalnej Strefy Demograficznej odwołują się do strukturalno-systemowych teorii społeczeństwa. Stan katastrofy demograficznej wymaga, moim zdaniem, przeprowadzenia reprezentatywnych badań empirycznych wśród młodego pokolenia, opracowania socjologicznego studium i uzupełnienia teoretycznych założeń Specjalnej Strefy Demograficznej w regionie opolskim.

A Time-Non-Homogeneous Double-Ended Queue with Failures and Repairs and Its Continuous Approximation

2018

We consider a time-non-homogeneous double-ended queue subject to catastrophes and repairs. The catastrophes occur according to a non-homogeneous Poisson process and lead the system into a state of failure. Instantaneously, the system is put under repair, such that repair time is governed by a time-varying intensity function. We analyze the transient and the asymptotic behavior of the queueing system. Moreover, we derive a heavy-traffic approximation that allows approximating the state of the systems by a time-non-homogeneous Wiener process subject to jumps to a spurious state (due to catastrophes) and random returns to the zero state (due to repairs). Special attention is devoted to the cas…
