A Simple Global Perspective on the US Slowdown, Boom-Bust Cycles and the Rise of Protectionism

The global economy has experienced several significant developments during the recent years: the rising role of giant Asian economies in international trade; the 2008 financial crisis and the ensuing Great Recession in the US, with its propagation to the rest of the world; the sharp rise and subsequent burst of commodity prices over 2006-2009. In this paper we use a multi-region DSGE model for the global economy as a simple framework to understand the global response to these shocks and the importance of the propagation to different regions. The model is equipped to jointly determine exchange rates, trade balances and commodity prices across the world. We carry out several simulations with the model. First, we consider the US slowdown and its international propagation. Second, we explore a global boom-bust cycle driven by overoptimistic forecasts for productivity and their relationship with current account rebalancing. Finally, we analyze the global economic consequences of protectionism. We find that the effects in commodity prices, global output and demand tend to be amplified if the real exchange rates and real wages are more sluggish to adjust in some regions.

A detection method of intersections for determining overlapping using active vision

Sometimes, the presence of objects difficult the observation of other neighboring objects. This is because part of the surface of an object occludes partially the surface of another, increasing the complexitiy in the recognition process. Therefore, the information which is acquired from scene to describe the objects is often incomplete and depends a great deal on the view point of the observation. Thus, when any real scene is observed, the regions and the boundaries which delimit and dissociate objects from others are not perceived easily. In this paper, a method to discern objects from others, delimiting where the surface of each object begins and finishes is presented. Really, here, we look for detecting the overlapping and occlusion zones of two or more objects which interact among each other in a same scene. This is very useful, on the one hand, to distinguish some objects from others when the features like texture colour and geometric form are not sufficient to separate them with a segmentation process. On the other hand, it is also important to identify occluded zones without a previous knowledge of the type of objects which are wished to recognize. The proposed approach is based on the detection of occluded zones by means of structured light patterns projected on the object surfaces in a scene. These light patterns determine certain discontinuities of the beam projections when they hit against the surfaces becoming deformed themselves. So that, such discontinuities are taken like zones of boundary of occlusion candidate regions

Conocimientos de la población estudiantil en Reanimación Cardiovascular Básica

Introducción: La Parada Cardiorrespiratoria (PCR) es la interrupción brusca, inesperada y potencialmente reversible de la respiración y la circulación espontánea. A nivel mundial se producen entre 4 y 5 millones de PCR al año. España tiene un ratio de una parada cada 20 minutos. Un 80% de las PCRs extrahospitalarias se producen en presencia de testigos, por ello la importancia de formación en de reanimación cardiopulmonar (RCP). Objetivo: Determinar la adquisición de competencias en RCP Básica en alumnos de primero del grado de enfermería de la Universidad Jaume I. Metodología: Estudio observacional transversal, en alumnos de primero del Grado de Enfermería de la Universidad Jaume I, con una población de 54 alumnos y una muestra de estudio del 94,44% (n=51), distribuida en tres grupos. El estudio se llevó a cabo en diciembre del 2016, mediante la cumplimentación de un pretest y un postest auto cumplimentable. El pretest previo a la realización de unas sesiones teórico-prácticas de RCP, y el postest tras la realización de estas sesiones teórico-prácticas. Los cuestionarios empleados, fueron de elaboración ad hoc evaluando su adecuación mediante grupo nominal de expertos, compuesto por seis profesionales. Para la explotación de los datos fue empleado el programa estadístico SPSS v.20 OSX. Resultados: La nota media obtenida en la sesión pretest fue de 5´5 puntos, un 29,41 % (n=15) de los alumnos no superó la prueba. En éste, la nota mínima obtenida fue de 2,5 puntos y la máxima de 8 puntos. La nota media obtenida en la sesión postest fue de 7,72 puntos, un 100% (n=50) superaron la prueba. En este, la nota mínima obtenida fue de 6,5 puntos y la máxima de 9 puntos. Conclusión: Se demuestra un aumento de los conocimientos medios en RCP del estudiantado participante, apreciándose un porcentaje mayor de calificaciones en el LAB-3.Introduction: Cardiorespiratory arrest is the sudden, unexpected and potentially reversible disruption of breathing and spontaneous circulation. Between 4 and 5 million cardiorespiratory arrest occur all around the world each year. Every 20 minutes someone suffers from them in Spain. 80% of out of hospital cardiorespiratory arrests occur in the presence of witnesses, that is the reason why effective training in cardiopulmonary resuscitation (CPR) is very important. Objective: To determine the acquisition of basic CPR skills among first year nursing students at Universitat Jaume I. Methods: Cross-sectional study conducted on first year nursing students at Universistat Jaume I, involving 54 students and a sample of 94,44% (n=51) distributes into 3 groups. The study took place in December 2016, by filling a pretest and a postest. The pretest was answered before some theoretical and practical CPR sessions and the postest after finishing those sessions. Ad hoc questionnaries were used by evaluating their suitability by means of a nominal group of experts, made up of six professionals on that field. The statistical programme SPSS v.20 OSX was used for the data exploitation. Results: The average mark on the pretest sessions was 5,5, 29,4% (n=15) of the students did not pass the test. The lowest mark was 2,5 and the highest 8. The average mark on the postest was 7,72, 100% of the students passed the test. The lowest mark was 6,5 and the highest 9. Conclusion: The study shows that CPR knowledge has higher marks among the LAB-3 students than among the other groups

Detection of partial occlusions of assembled components to simplify the disassembly tasks

An automatic disassembly cell requires of a computer vision system for recognition and localization of the products and each of theirs components. The detection of occlusions adds more information to the knowledge base to identify components and products, and generate a trustworthy and precise relational model (generic graph of hierarchic relations among the different components that make up the product). In this paper, a method to detect partial occlusions in assembled components is presented. This method is based on the fusion of regions and edges information, and it offers a certain degree of simplification for the recognition and modelled of the disassembly tasks, of the set of components which compose the product. The proposed approach to detect regions is a hybrid approach between RGB and HSV spaces. The bi-dimensional histogram V/S is employed for the selection of the appropriate thresholds which serve as an aid to diminish the influence of the highlights and shadows in images. The goal of this paper is to present an approach for the detection of occlusions in assembled components from a combination of HSV and RGB spaces, a bi-dimensional histogram and an edge detector.This work was funded by the following Spanish MCYT project “DESAURO: Desensamblado Automático Selectivo para Reciclado mediante Robots Cooperativos y Sistema Multisensorial” (MCYT (DPI2002-02103)

Extracorporeal membrane oxygenation improves survival in a novel 24-hour pig model of severe acute respiratory distress syndrome

Indexación: Web of Science; Pub Med CentralExtracorporeal membrane oxygenation (ECMO) is increasingly being used to treat severe acute respiratory distress syndrome (ARDS). However, there is limited clinical evidence about how to optimize the technique. Experimental research can provide an alternative to fill the actual knowledge gap. The purpose of the present study was to develop and validate an animal model of acute lung injury (ALI) which resembled severe ARDS, and which could be successfully supported with ECMO. Eighteen pigs were randomly allocated into three groups: sham, ALI, and ALI + ECMO. ALI was induced by a double-hit consisting in repeated saline lavage followed by a 2-hour period of injurious ventilation. All animals were followed up to 24 hours while being ventilated with conventional ventilation (tidal volume 10 ml/kg). The lung injury model resulted in severe hypoxemia, increased airway pressures, pulmonary hypertension, and altered alveolar membrane barrier function, as indicated by an increased protein concentration in bronchoalveolar fluid, and increased wet/dry lung weight ratio. Histologic examination revealed severe diffuse alveolar damage, characteristic of ARDS. Veno-venous ECMO was started at the end of lung injury induction with a flow > 60 ml/kg/min resulting in rapid reversal of hypoxemia and pulmonary hypertension. Mortality was 0, 66.6 and 16.6% in the SHAM, ALI and ALI + ECMO groups, respectively (p < 0.05). This is a novel clinically relevant animal model that can be used to optimize the approach to ECMO and foster translational research in extracorporeal lung support.http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4931177
