Le potentiel des technologies de l’information et des communications pour le renforcement de la résilience organisationnelle lors des opérations d’évacuation : é́tude de cas de la ville de New York

Lorsque les ouragans entrent en contact avec l'environnement bâti et naturel, les autorités publiques n'ont parfois d'autre choix que de déclarer l'évacuation obligatoire de la population située en zone à risque. En raison de l'imprévisibilité du déroulement d'une catastrophe et des comportements humains, les opérations d'évacuation sont confrontées à une incertitude significative. Les expériences passées ont montré que les technologies de l'information et des communications (TIC) ont le potentiel d'améliorer l'état de l'art en gestion des évacuations. Malgré cette reconnaissance, les recherches empiriques sur ce sujet sont à ce jour limitées. La présente étude de cas de la ville de New York explore comment l'intégration des TIC dans la planification opérationnelle des organisations ayant des responsabilités en matière de transport peut améliorer leurs réponses aux événements et influencer le succès global du système de gestion des catastrophes. L'analyse est basée sur les informations recueillies au moyen d'entretiens semi-dirigés avec les organisations de transport et de gestion des catastrophes de la ville de New York ainsi qu’avec des experts du milieu universitaire. Les résultats mettent en lumière le potentiel des TIC pour la prise de décision en interne. Même s’il est largement reconnu que les TIC sont des moyens efficaces d'échanger de l'information en interne et entre les organisations, ces usages sont confrontés à certaines contraintes technologique, organisationnelle, structurelle et systémique. Cette observation a permis d'identifier les contraintes vécues dans les pratiques usuelles de gestion des systèmes urbains.

Hermenêutica botânica e antropização na Amazônia: exsicatas de verbenáceas da Amazônia Legal no Herbário do New York Botanical Garden

Este artigo tem como base informações de uma série histórica de exsicatas datadas de 1819 a 2002, reunindo contribuições de pesquisadores de instituições governamentais e não governamentais das Américas do Norte, do Sul e Europa. Tem foco nas verbenáceas, pela reconhecida gama de espécies aromáticas e medicinais desta família e o seu reconhecido uso no Brasil. Analisa notas descritivas e críticas sobre a coleção do New York Botanical Garden referente à Amazônia, revelando o espírito da cooperação entre instituições brasileiras e estrangeiras nesta região. Alterações do meio ambiente, rede de pesquisadores, mudanças na linguagem, na tecnologia dos registros e absorção de termos regionais são detectados ao longo de quase dois séculos de trabalho científico em que se projeta a formação continuada de cientistas e a interação com saberes locais.

An Ardent Flame: Witness to Distant Suffering, Human Rights and Unworthy Victims in the Coverage by The New York Times and Two Journals of the Religious Left of the 1980s Civil Wars in El Salvador and Nicaragua

Scholars have investigated witness to distant suffering (WTDS) almost entirely in visual media. This study examines it in print. This form of reporting will be examined in two publications of the religious left as contrasted with the New York Times. The thesis is that, more than any technology, WTDS consists of the journalist’s moral commitment and narrative skills and the audience’s analytical resources and trust. In the religious journals, liberation theology provides the moral commitment, the writers and editors the narrative skills and trust and the special vision of the newly empowered poor the analytical foundation. In bearing witness to those who have suffered state or guerilla terrorism in El Salvador and Nicaragua during the 1980s, we will investigate a distinction between “worthy” and “unworthy victims.” This last issue has a special ethical and political significance. Media witnessing to the suffering of strangers can help them become known, and so “worthy.” It can help them, and their plight and cause, become better recognized. This is the power of the media.

DEVELOPMENT OF A CONCEPTUAL MODEL AND PARAMETERIZATION OF A MATHEMATICAL MODEL FOR SEDIMENT PHOSPHORUS DIAGENESIS, SORPTION AND RELEASE FROM ONONDAGA LAKE SYRACUSE, NEW YORK

Eutrophication is a persistent problem in many fresh water lakes. Delay in lake recovery following reductions in external loading of phosphorus, the limiting nutrient in fresh water ecosystems, is often observed. Models have been created to assist with lake remediation efforts, however, the application of management tools to sediment diagenesis is often neglected due to conceptual and mathematical complexity. SED2K (Chapra et al. 2012) is proposed as a "middle way", offering engineering rigor while being accessible to users. An objective of this research is to further support the development and application SED2K for sediment phosphorus diagenesis and release to the water column of Onondaga Lake. Application of SED2K has been made to eutrophic Lake Alice in Minnesota. The more homogenous sediment characteristics of Lake Alice, compared with the industrially polluted sediment layers of Onondaga Lake, allowed for an invariant rate coefficient to be applied to describe first order decay kinetics of phosphorus. When a similar approach was attempted on Onondaga Lake an invariant rate coefficient failed to simulate the sediment phosphorus profile. Therefore, labile P was accounted for by progressive preservation after burial and a rate coefficient which gradual decreased with depth was applied. In this study, profile sediment samples were chemically extracted into five operationally-defined fractions: CaCO3-P, Fe/Al-P, Biogenic-P, Ca Mineral-P and Residual-P. Chemical fractionation data, from this study, showed that preservation is not the only mechanism by which phosphorus may be maintained in a non-reactive state in the profile. Sorption has been shown to contribute substantially to P burial within the profile. A new kinetic approach involving partitioning of P into process based fractions is applied here. Results from this approach indicate that labile P (Ca Mineral and Organic P) is contributing to internal P loading to Onondaga Lake, through diagenesis and diffusion to the water column, while the sorbed P fraction (Fe/Al-P and CaCO3-P) is remaining consistent. Sediment profile concentrations of labile and total phosphorus at time of deposition were also modeled and compared with current labile and total phosphorus, to quantify the extent to which remaining phosphorus which will continue to contribute to internal P loading and influence the trophic status of Onondaga Lake. Results presented here also allowed for estimation of the depth of the active sediment layer and the attendant response time as well as the sediment burden of labile P and associated efflux.

Synoptic Analysis of the New York March 1888 Blizzard

The meteorological circumstances that led to the Blizzard of March 1888 that hit New York are analysed in Version 2 of the “Twentieth Century Reanalysis” (20CR). The potential of this data set for studying historical extreme events has not yet been fully explored. A detailed analysis of 20CR data alongside other data sources (including historical instrumental data and weather maps) for historical extremes such as the March 1888 blizzard may give insights into the limitations of 20CR. We find that 20CR reproduces the circulation pattern as well as the temperature development very well. Regarding the absolute values of variables such as snow fall or minimum and maximum surface pressure, there is anunderestimation of the observed extremes, which may be due to the low spatial resolution of 20CR and the fact that only the ensemble mean is considered. Despite this drawback, the dataset allows us to gain new information due to its complete spatial and temporal coverage.
