The Role and Function of the Liaison Officer: Lessons Learned and Applied after Superstorm Sandy.

In October 2012, Superstorm Sandy had a wide impact on the public across New York City (NYC). The NYC Department of Health and Mental Hygiene (DOHMH) activated its incident command system (ICS) and deployed a liaison officer (LNO) to the NYC Emergency Operations Center (EOC) at NYC Emergency Management (NYCEM) 24 hours a day for 6 weeks. This prolonged response period, coupled with environmental effects on NYC's coastal communities, increased public awareness of Sandy's health impacts, requiring a broad scope of interagency coordination and operational input from the liaison officer. Liaison officers involved in this response later conducted a content analysis of issues handled throughout Sandy, to better understand the skill set required to serve in this role, identify greater staff depth, integrate liaison officers into DOHMH exercises, and update just-in-time training provided before liaison officers deploy. This analysis revealed defined training topics for liaison officers to improve staff performance and effectiveness in leading interagency coordination during emergency responses. Topics include resources, staffing, data management, public messaging, and vulnerable populations, and these topics have since been used to revamp liaison officer training and guide policy changes in the liaison officer job charter. Targeted use of liaison officers to support development and implementation and to coordinate response objectives with local, state, and federal partners has only become more important. This analysis continues to influence how DOHMH defines its citywide agency response role, to inform how best to staff and train liaison officers to respond, and to pose lessons for other jurisdictions seeking to maximize the effectiveness of liaison officers deployed in emergencies.

Contribución a la flora altoandina del distrito de Oyón, región Lima, Perú / Contribution to Andean flora from Oyón District , Lima, Peru

En este trabajo se presenta el inventario de plantas vasculares de montaña alta (altitudes de 4000 a 4810 m) del noreste del distrito de Oyón, región Lima, Perú. Las colectas se realizaron durante los periodos marzo a mayo de 2014 y de 2015, y setiembre a noviembre de 2014. Se encontraron 47 familias, 112 géneros y 181 especies, de las cuales 94 no estaban registradas para la región Lima. Se presenta la lista de todas las especies encontradas con referencia a los colectores, número de colecta y altitud de colecta. Se argumenta la necesidad de multiplicar los inventarios botánicos locales que permitirían conocer mejor la diversidad de la flora, la distribución de las especies, y los endemismos en la vegetación altoandina.

In this paper, the inventory of vascular plants of high mountains (altitudes of 4000-4810 m) from northeast Oyon district, Lima, Peru is presented. Specimens were collected during March to May 2014 and 2015 and September to November 2015. 47 families, 112 genera and 181 species are reported, of which 94 were the first record for Lima region. For each species are given collector names, collect number and elevation. New local botanical inventories are needed for better evaluating the diversity, species distribution patterns and endemism in the high Andean vegetation.

Structure et dynamisme de la forêt

Résumé Les auteurs comparent la structure de la végétation de deux toposéquences choisies dans les bassins versants de la ZF-02. Pour ce faire, ils utilisent une méthode de description morpho-structurale de la végétation dont ils rappellent I'essentiel. Ils discutent des variations selon la position sur la toposéquence et de leurs causes. Ces résultats sont comparés à deux autres séquences. Répartition en classes de diamètres, aire basale sont interprétées en fonction du cycle silvigénétique. Cette analyse montre I'homogénéité de la forêt dans cette région et I'existence d'un segment toposéquentiel de végétation. Le principal facteur de variation est le cycle silvigénétique, consideré comme processus d'autorégénération par création et cicatrisation de chablis.

Resumo Os autores fazem um estudo comparativo da estrutura da vegetação de duas toposseqüências nas bacias hidrográficas da ZF-02, segundo um método morfo-estrutural do que recordam o essencial. Discutem as variações na toposseqüência e os fatores de variação. Comparam os resultados com duas outras toposseqüências. Alguns parâmetros quantitativos, diâmetro, área basal, são interpretados em função do ciclo silvigenético. Esta análise evidencia a homogeneidade da vegetação florestal nesta área, e a existência de uma unidade estrutural da toposseqüência. O principal fator de variação é o ciclo silvigenético, processo de auto-regeneração da floresta pela queda das árvores e a cicatrização das clareiras naturais.
