Collaboration and Decision Making in Crisis Situations

[EN] Emergencies are critical situations that demand immediate action to avoid adverse consequences to life and property. Recent events around the world highlight the importance of the theme. A key challenge in Emergency Management is decision-making under time pressure, with an overload of unconfirmed, uncertain and conflicting information, including the management of many people, with distinct and possibly fluid roles, in different places. Collaboration in these settings is an interesting element, since emergency response generally involves multiple agencies and the public, which, having different views, protocols and priorities, must act in concert to handle the situation. In addition, an increasing amount of virtual information is necessary to inform and manage volunteers. The goal of this workshop is to identify and map the main challenges of collaboration in crisis situations, review current research methods and approaches to address them and address the lack of formal processes, structures, methodologies and tools.Adriana S Vivacqua is partially supported by CNPq grant 308425/2012-0 and FAPERJ grant E26/103.029/2012.

The catalogs of the superior music conservatories: identification, analysis and evaluation.

The online catalogs (OPACs) belonging to the libraries of the Superior Music Conservatories are evaluated. To achieve this goal, we begin by analyzing the scientific literature on the subject. The study population is then identified through the consultation of the Directory of Spanish Libraries, the website of the Spanish Association of Higher Schools of Artistic Teaching and the Map of Conservatories of Music of Spain recently created. For the analysis of the catalogs we opted for the creation of an ad hoc evaluation instrument defining the following parameters: Presentation, retrieval of information, export of records, bibliographic services, user attention, diffusion and social OPAC. It concludes by highlighting the main results obtained and establishing a series of proposals for improvements

Microcavity exciton-polariton mediated Raman scattering: Experiments and theory

We studied the intensity of resonant Raman scattering due to optical phonons in a planar II-VI-type semiconductor microcavity in the regime of strong coupling between light and matter. Two different sets of independent experiments were performed at near outgoing resonance with the middle polariton (MP)branch of the cavity. In the first, the Stokes-shifted photons were kept at exact resonance with the MP, varying the photonic or excitonic character of the polariton. In the second, only the incoming light wavelength was varied, and the resonant profile of the inelastic scattered intensity was studied when the system was tuned out of the resonant condition. Taking some matrix elements as free parameters, both independent experiments are quantitatively described by a model which incorporates lifetime effects in both excitons and photons, and the coupling of the cavity photons to the electron-hole continuum. The model is solved using a Green's function approach which treats the exciton-photon coupling nonperturbatively.Comment: 10 pages, 6 figure

High-K dielectric sulfur-selenium alloys.

Upcoming advancements in flexible technology require mechanically compliant dielectric materials. Current dielectrics have either high dielectric constant, K (e.g., metal oxides) or good flexibility (e.g., polymers). Here, we achieve a golden mean of these properties and obtain a lightweight, viscoelastic, high-K dielectric material by combining two nonpolar, brittle constituents, namely, sulfur (S) and selenium (Se). This S-Se alloy retains polymer-like mechanical flexibility along with a dielectric strength (40 kV/mm) and a high dielectric constant (K = 74 at 1 MHz) similar to those of established metal oxides. Our theoretical model suggests that the principal reason is the strong dipole moment generated due to the unique structural orientation between S and Se atoms. The S-Se alloys can bridge the chasm between mechanically soft and high-K dielectric materials toward several flexible device applications

Concentración dietaria óptima de aminoácidos azufrados utilizando L-metionina en el alimento inicial de patos Muscovy (Cairina moschata Linnaeus, 1758)

This study evaluated the effect of supplementing increasing levels of L-methionine (L-Met) in the diet for Muscovy ducks from hatch to 21 days of age. A total of 90 male Muscovy ducklings were assigned to 30 pens with 3 birds per pen. A basal diet with corn, soybean and wheat by-product was supplemented with 0, 0.08, 0.16, 0.24, 0.32 and 0.40% L-Met, obtaining 6 diets with increasing concentrations of sulfur amino acids, but constant in energy and other essential nutrients. Analysis of variance and Tukey's mean comparison test were performed. In addition, an effective dose-response model was performed to determine the optimal methionine level. Body weight and feed intake were not influenced (p>0.05) by L-Met supplementation, although a numerical trend towards greater weights was observed as supplementation increased. Feed conversion was significantly better with 0.24 and 0.32% L-Met supplementation (p<0.05), deteriorating when supplemented with 0.08% L-Met. The adequate concentration to reach the optimum body weight was determined at 0.44 and 0.72% for Met and Met+Cys, respectively. while the adequate concentration to achieve the best feed conversion efficiency was determined at 0.40 and 0.68% for Met and Met+Cis, respectively.La presente investigación evaluó el efecto de la suplementación de niveles crecientes de L-metionina (L-Met) en la dieta para patos Muscovy desde el nacimiento hasta los 21 días de edad. Se utilizaron 90 patos Muscovy machos recién nacidos asignados a 30 corrales con 3 aves por corral. Una dieta basal con maíz, soya y subproducto de trigo fue suplementada con 0, 0.08, 0.16, 0.24, 0.32 y 0.40% L-Met, dando lugar a 6 dietas con concentraciones crecientes en aminoácidos azufrados pero constantes en energía y demás nutrientes esenciales. Se realizó el análisis de variancia y la prueba de comparación de medias de Tukey. Además, un modelo dosis-respuesta efectiva fue realizado para determinar el nivel de metionina óptimo. El peso corporal y el consumo de alimento no fueron influenciados (p>0.05) por la suplementación de L-Met aunque se observó una tendencia numérica a mayores pesos conforme se incrementaba la suplementación. La conversión alimenticia fue significativamente mejor con la suplementación de 0.24 y 0.32% de L-Met (p<0.05), deteriorándose cuando se suplementó con 0.08% L-Met. La concentración adecuada para alcanzar el óptimo peso corporal fue determinada en 0.44 y 0.72% para Met y Met+Cis, respectivamente. Mientras que la concentración adecuada para alcanzar la mejor eficiencia de conversión alimenticia fue determinada en 0.40 y 0.68% para Met y Met+Cis, respectivamente

There is a pressing technological need for the better representation of biomedical protocols to enable other agents (human or machine) to better reproduce results. A framework that ensures that all information required for the replication of experimental protocols is essential to achieve reproducibility. Methods: We have developed the ontology EXACT2 (EXperimental ACTions) that is designed to capture the full semantics of biomedical protocols required for their reproducibility. To construct EXACT2 we manually inspected hundreds of published and commercial biomedical protocols from several areas of biomedicine. After establishing a clear pattern for extracting the required information we utilized text-mining tools to translate the protocols into a machine amenable format. We have verified the utility of EXACT2 through the successful processing of previously ‘unseen’ (not used for the construction of EXACT2) protocols. Results: The paper reports on a fundamentally new version EXACT2 that supports the semantically-defined representation of biomedical protocols. The ability of EXACT2 to capture the semantics of biomedical procedures was verified through a text mining use case. In this EXACT2 is used as a reference model for text mining tools to identify terms pertinent to experimental actions, and their properties, in biomedical protocols expressed in natural language. An EXACT2-based framework for the translation of biomedical protocols to a machine amenable format is proposed. Conclusions: The EXACT2 ontology is sufficient to record, in a machine processable form, the essential information about biomedical protocols. EXACT2 defines explicit semantics of experimental actions, and can be used by various computer applications. It can serve as a reference model for for the translation of biomedical protocols in natural language into a semantically-defined format.This work has been partially funded by the Brunel University BRIEF award and a grant from Occams Resources
