Local LGCP estimation for spatial seismic processes

2020

Using recent results for local composite likelihood for spatial point processes, we show the performance of advanced and flexible statistical models to describe the spatial displacement of earthquake data. Local models described by Baddeley (2017) allow for the possibility of describing both seismic catalogs and sequences. When analysing seismic sequences, the analysis of the small scale variation is the main issue. The interaction among points is taken into account by Log-Gaussian Cox Processes models through the estimation of the parameters of the covariance of the Gaussian Random Field. In their local version these parameters are allowed to vary spatially, and this is a crucial aspect fo…

Detection of spatio-temporal local structure on seismic data

2017

For the description of the seismicity of an area, the comparison between local features of background and induced events could be a new perspective of research. In spatio-temporal point process, local second-order statistics provide information on the relationships of each event and its nearby events. In this paper, we use a test based on local indicators of spatio-temporal association (LISTA functions) for identifying different local structures comparing the two previous sets of events. We present a simulation study on the test and show the main results of the application on Greece earthquake data.

Advanced spatio-temporal point processes for the Sicily seismicity analysis

2018

Due to the complexity of the generator process of seismic events, we study under several aspects the interaction structure between earthquake events using recently developed spatio-temporal statistical techniques and models. Using these advanced statistical tools, we aim to characterise the global and local scale cluster behaviour of the Easter Sicily seismicity considering the catalogue data since 2006, when the Italian National Seismic Network was upgraded and earthquake location was sensibly improved. Firstly, we characterise the global complex spatiotemporal interaction structure with the space-time ETAS model where background seismicity is estimated non-parametrically, while triggered …

Global Perspective on Marital Satisfaction

2020

Across the world, millions of couples get married each year. One of the strongest predictors of whether partners will remain in their relationship is their reported satisfaction. Marital satisfaction is commonly found to be a key predictor of both individual and relational well-being. Despite its importance in predicting relationship longevity, there are relatively few empirical research studies examining predictors of marital satisfaction outside of a Western context. To address this gap in the literature and complete the existing knowledge about global predictors of marital satisfaction, we used an open-access database of self-reported assessments of self-reported marital satisfaction wit…

Natural Laboratories for Field Observation About Genesis and Landscape Effects of Palaeo-Earthquakes: a Proposal for the Rocca Busambra and Monte Bar…

2018

Earthquakes are phenomena that are still being learned by the scientific community, and poorly known, especially as regards the prevention, by the population. Having a more complete knowledge is a basic step in understanding the vastness and intensity of the destructive phenomenon that involves a great amount of people. The recent earthquakes occurred in Central Italy (L’Aquila and Amatrice earthquakes) are examples that demonstrate the importance of having knowledge about these phenomena to contrast their destructive effects. We present a geological field trip to recognise causes and landscape effects of palaeo-earthquakes recorded in the Mesozoic rock successions outcropping in Sicily. Th…

Se soigner en zone rurale lorraine : Domestication du système de soin et encadrement familial des trajectoires individuelles

2018

Cadre de la recherche : À l’articulation de la socioanthropologie de la famille et de la santé, la recherche interroge l’intervention de la famille à tous les âges de la vie et à différents temps de la gestion des problèmes de santé en zone rurale. Objectifs : S’appuyant sur une recherche qualitative que nous avons menée en Lorraine (France), cet article examine les influences et les actions des membres du réseau familial et de l’entourage dans la construction des itinéraires de soins.Méthodologie : En Lorraine rurale, une enquête socioanthropologique par entretiens semi-directifs a été réalisée de 2013 à 2015 auprès de 48 personnes âgées de 25 à 94 ans. Nous avons enquêté dans des territoi…

'The Ideological Framework of the French Nouvelle Droite and the Contemporary Finnish Far Right'

2015

This article deals with the xenophobic discourse of contemporary Finnish anti-immigrationists, namely the anti-immigration faction of the Perussuomalaiset party and its 'metapolitical' background organisation - Suomen Sisu. It focuses on two main themes - differentialism and anti-egalitarianism - as they have been conceptualised by the French Nouvelle Droite (ND) and the European New Right. Because these themes have been used to serve a variety of anti-immigration movements and parties within Europe, the article examines whether the selective reception of differentialism and anti-egalitarianism have a part to play in the xenophobic discourse within Finnish politics as well. The Finnish anti…

Flexible space-time process for seismic data

2009

Point processes are well studied objects in probability theory and a powerful tool in statistics for modelling and analyzing the distribution of real phenomena, such as the seismic one. Point processes can be specified mathematically in several ways, for instance, by considering the joint distributions of the counts of points in arbitrary sets or defining a complete intensity function. The conditional intensity function is a function of the point history and it is itself a stochastic process depending on the past up to time t. In this paper some techniques to estimate the intensity function of space-time point processes are developed, by following semi-parametric approaches and diagnostic m…
