Missing Data in Space-time: Long Gaps Imputation Based On Functional Data Analysis
2017
High dimensional data with spatio-temporal structures are of great interest in many elds of research, but their exhibited complexity leads to practical issues when formulating statistical models. Functional data analysis through smoothing methods is a proper framework for incorporating space-time structures: extending the basic methodology to the multivariate spatio-temporal setting, we refer to Generalized Additive Models for estimating functional data taking the spatial and temporal dependences into account, and to Functional Principal Component Analysis as a classical dimension reduction technique to cope with the high dimensionality and with the number of estimated eects. Since spatial …
Mourning Missing Migrants: Ambiguous Loss and the Grief of Strangers
2019
While the term missing refers to various instances and practices, we focus on the bodies of deceased migrants that remain unidentified, and on the inability of families to mourn someone when there is no body to grieve for. We deploy some ethnographic fragments of how Italian communities sometimes mourn those who are buried without a name and we describe the many problems of mourning someone whose fate is unknown through a discussion of the notion of ‘ambiguous loss’. Our contribution articulates some of the politics around deaths in migration by considering how missing migrants and their bodies are mourned in multiplicity. peerReviewed
Search for photonic signatures of gauge-mediated supersymmetry in 8TeV pp collisions with the ATLAS detector
2015
A search is presented for photonic signatures motivated by generalized models of gauge-mediated supersymmetry breaking. This search makes use of 20.3 fb[superscript −1] of proton-proton collision data at √s = 8 TeV recorded by the ATLAS detector at the LHC, and explores models dominated by both strong and electroweak production of supersymmetric partner states. Four experimental signatures incorporating an isolated photon and significant missing transverse momentum are explored. These signatures include events with an additional photon, lepton, b-quark jet, or jet activity not associated with any specific underlying quark flavor. No significant excess of events is observed above the Stand…
