Behavioural Expertise: Drift, Thrift and Shift under COVID-19

open access: yesInternational Review of Public Policy, 2022
Many government responses to the coronavirus-pandemic have been marked by attempts at expertization and scientization. Particularly, politico-epistemological authority is being given to the behavioural science community consulting government.

Simulation of cluster point processes without edge effects [PDF]

open access: yes, 2002
The usual direct method of simulation for cluster processes requires the generation of the parent point process over a region larger than the actual observation window, since we have to allow for all possible parents giving rise to observed daughter ...

Bias-Correction and Test for Mark-Point Dependence with Replicated Marked Point Processes

open access: yesJournal of the American Statistical Association, 2022
Mark-point dependence plays a critical role in research problems that can be fitted into the general framework of marked point processes. In this work, we focus on adjusting for mark-point dependence when estimating the mean and covariance functions of the mark process, given independent replicates of the marked point process.

Neural Spectral Marked Point Processes

open access: yes, 2021
Self- and mutually-exciting point processes are popular models in machine learning and statistics for dependent discrete event data. To date, most existing models assume stationary kernels (including the classical Hawkes processes) and simple parametric models.

A Marked Point Process for Modeling Lidar Waveforms [PDF]

open access: yesIEEE Transactions on Image Processing, 2010
Lidar waveforms are 1-D signals representing a train of echoes caused by reflections at different targets. Modeling these echoes with the appropriate parametric function is useful to retrieve information about the physical characteristics of the targets.

Catastrophe Insurance Modeled by Shot-Noise Processes

open access: yesRisks, 2014
Shot-noise processes generalize compound Poisson processes in the following way: a jump (the shot) is followed by a decline (noise). This constitutes a useful model for insurance claims in many circumstances; claims due to natural disasters or self ...

Ecology and digital technologies. Small-scale architecture as a place of connections

open access: yesAgathón, 2021
Starting from the relationships between digital technologies and environmental culture, the essay aims to outline the contours of the new ecological dimension of architectural design as a place of multiple and interacting connections in which we can ...

Summary statistics for inhomogeneous marked point processes [PDF]

open access: yes, 2016
We propose new summary statistics for intensity-reweighted moment stationary marked point processes with particular emphasis on discrete marks. The new statistics are based on the $n$-point correlation functions and reduce to cross $J$- and $D$-functions

Recorrido por la jurisprudencia sobre los denominados «Alardes»: una fiesta plagada de conflictos

open access: yesEstudios de Deusto, 2012
The celebration of the so called «Alardes» in diverse Basque localities has been the starting point of constant judicial conflicts since the 90´s. Without denying the sociological dimension of such controversies, it must be recognized that, from a ...
