Using administrative data to estimate population displacement and resettlement following a catastrophic U.S. disaster
After a large scale evacuation, authorities need to know the new and frequently changing population distributions in order to meet needs for housing, schools, health care, and other services. This paper reviews literature from the fields of demography and other disciplines to identify available administrative data sets that can form the basis of sound, relevant, and timely county-level population estimates following a catastrophic U.S. event. The most appropriate data to estimate population in damaged counties will be disaster-specific data such as housing damage estimates and FEMA applicant counts initially, and later electric accounts and USPS active residences. In heavily damaged counties, data on electric accounts and USPS active residences may not be consistently collected for many months, during which time sample surveys may be needed. For counties that receive an influx of population, school enrollment data provide the most appropriate basis for population estimates. Population estimates for large, heavily damaged counties are highly uncertain. Sensitivity analysis when using estimates for planning in these areas is recommended. The Census Bureau can build on this research by codifying recommendations to local authorities for developing frequent post-disaster population estimates
Restaurer la sensibilité au paysage
Notre terrain dâĂ©tude, lâextrĂ©mitĂ© orientale du district de Hradec KrĂĄlovĂ© (RĂ©publique tchĂšque), a connu deux mouvements de patrimonialisation successifs depuis la Seconde Guerre mondiale, par les anciens habitants germanophones expulsĂ©s aprĂšs 1945 puis par des associations locales tchĂšques qui cherchent aujourdâhui Ă augmenter lâattractivitĂ© de leur rĂ©gion. Il leur arrive dâailleurs de collaborer ; mais plus fondamentalement, leur dĂ©marche est dâune Ă©tonnante similitude en ce qui concerne la valeur accordĂ©e au paysage. Lâanalyse de leurs publications montre en effet que le paysage, dĂ©crit dans les Ă©tudes sur le nationalisme en Europe centrale comme un Ă©lĂ©ment majeur pour construire la nation, est ici conçu au premier chef comme une ressource morale, apte Ă refaire du lien social (par exemple en y rĂ©parant les chemins), comme Ă restaurer la capacitĂ© sensible de ses visiteurs, donc lâestime de soi et la capacitĂ© Ă se projeter dans un avenir durable. Ceci rejoint de maniĂšre Ă©tonnante les prĂ©occupations exprimĂ©e en Angleterre dĂšs la premiĂšre moitiĂ© du xixe siĂšcle Ă propos du paysage menacĂ© par lâaction de lâhomme â ici, lâindustrialisation â et les efforts faits pour conserver certains paysages remarquables comme rĂ©sultat dâune interaction sĂ©culaire entre lâhomme et son environnement. Par-delĂ les diffĂ©rences de pĂ©riode et de contexte, on voit donc ici Ă lâĆuvre une mĂȘme conception europĂ©enne du paysage, certes romantique, mais qui nâest pas nationale.We studied two attempts to define and preserve the worthwhile past of a small region between the Sudeten mountains and Silesia in the Eastern part of the Czech republic : first by the expelled German-speaking inhabitants collecting memories in exile after 1945, then by Czech associations founded in the aftermath of the âVelvet revolution.â Both show an amazing similarity in their conception of the landscape as a therapeutic resource for individuals and for local society, harmed by war, expulsion or a ruthless dictatorship disregarding human rights and environment. They both aim at restoring the ties of the former or actual inhabitants with the outstanding beauty of the local landscape, either by publishing imaginary walks through the region that had just expelled them or by preserving nature and historical buildings. Hence humans and society seek a cure for their feeling of estrangement, which could lead to despair, lack of self-confidence and inability to imagine a sustainable future. This conception reminds us of the first European attempt to protect an endangered landscape, the English Lake district movement in the first half of the nineteenth century, which shows that the celebration of natural scenery in Central Europe, though no doubt romantic, is not necessarily an attempt to nationalize nature

How Data Became Part of New Orleansâ DNA during the Katrina Recovery
Data intermediaries have a symbiotic relationship with government as the source of most of their information. The open-data movement in government and development of software-as-a-service technologies shaped the data landscape after Katrina. Through relationships and talent transfers with The Data Center, the City of New Orleans went from having its chief technology officer in federal prison and its data systems in shambles to being a nationally recognized leader in open and accountable government. To be effective during disasters, an intermediary should be (1) in place and widely respected before the event, (2) ready to respond immediately after the event and for the long recovery, and (3) continually scanning the horizon for changes in data and technology

Brandes, Detlef, Die Sudetendeutschen im Krisenjahr 1938
Le soixante-dixiĂšme anniversaire des accords de Munich a incitĂ© D.B., spĂ©cialiste des relations tchĂ©co-allemandes, Ă entreprendre une Ă©tude de lâopinion sudĂšte. InspirĂ© par son homologue tchĂšque Jan Kâen, pour qui lâexpulsion des Allemands des SudĂštes en 1945 avait fait consensus Ă cause de lâextrĂȘme dĂ©gradation de leurs relations avec les TchĂšques juste avant la guerre (p. VII et p. 319), il se penche sur la pĂ©riode allant de 1935 (lorsque Konrad Henlein remporte 60% des voix allemandes aux ..
GwĂ©nola Sebaux (dir.), IdentitĂ©s, migrations et mobilitĂ©s transnationales. Europe (xixe-xxie siĂšcle). Ătude de cas : Allemagne, Autriche, Roumanie, France, IsraĂ«l
Les mobilitĂ©s, câest bien connu, sont lâantithĂšse de la stabilitĂ© dont les identitĂ©s collectives ont besoin pour se constituer et qui, pour les plus abouties, sâappuient sur lâĂtat et ses moyens administratifs et coercitifs, ces derniers incluant le contrĂŽle des dĂ©placements de population. NĂ©anmoins, lâhistoire contemporaine de lâEurope continentale ou projetĂ©e outre-mer, Ă©tudiĂ©e ici au travers dâexemples allemands, autrichiens et roumains, français et israĂ©liens, est en contradiction avec ce..

Ă lâheure oĂč disparaissent les derniers tĂ©moins des dĂ©portations de la Seconde Guerre mondiale, quelles traces cette expĂ©rience laisse-t-elle en Europe ? En se saisissant de cette question, lâouvrage collectif et interdisciplinaire dirigĂ© par M. FabrĂ©guet et D. Henky (UniversitĂ© de Strasbourg) fait le pari dâenrichir lâhistoire europĂ©enne du phĂ©nomĂšne de la dĂ©portation, vu aprĂšs 1945 au travers dâun prisme national insistant sur les prisonniers de guerre et les rĂ©sistants, puis Ă©clairĂ© par la..
Learning fluid trajectory models for time-resolved PIV
International audienceWe present a new multiframe cross-correlation (Lucas-Kanade based) algorithm for time-resolved PIV. This algorithm leverages time coherence in image sequences by decomposing the temporal dependency of motion on an arbitrarily chosen trajectory basis. We propose to learn this basis from the data by performing a Principal Component Analysis on trajectories sampled from the studied sequence. We show on simulated data that such an approach can outperform the polynomial models classically used in multiframe PIV
