Las políticas públicas regionales y sus dimensiones institucionales. Apuntes teóricos y un análisis de caso

En el artículo se aborda el tema de las políticas públicas regionales como una de las apuestas estratégicas de renovada vigencia en el marco de los procesos de integración en América Latina. En primer lugar se formulan algunas reflexiones teóricas sobre el particular, en lo que se pone especial énfasis en las dimensiones institucionales involucradas en el diseño y la implementación de este tipo de políticas. En segundo lugar se presenta en forma su- cinta un estudio de caso focalizado en un asunto paradigmático: el despliegue de estrategias de manejo integrado en el marco de una cuenca plurinacional como la Cuenca del Río de la Plata. En ambas perspectivas se procura destacar tanto la relevancia estratégica de las políticas públicas regionales como la compleji- dad y la hondura de las dimensiones propiamente institucionales de esa operativa

Embedding Multi-Task Address-Event- Representation Computation

Address-Event-Representation, AER, is a communication protocol that is intended to transfer neuronal spikes between bioinspired chips. There are several AER tools to help to develop and test AER based systems, which may consist of a hierarchical structure with several chips that transmit spikes among them in real-time, while performing some processing. Although these tools reach very high bandwidth at the AER communication level, they require the use of a personal computer to allow the higher level processing of the event information. We propose the use of an embedded platform based on a multi-task operating system to allow both, the AER communication and processing without the requirement of either a laptop or a computer. In this paper, we present and study the performance of an embedded multi-task AER tool, connecting and programming it for processing Address-Event information from a spiking generator.Ministerio de Ciencia e Innovación TEC2006-11730-C03-0

Modelo de proceso basado en BPM para la mejora del indicador de calidad throughput en la implementación de una estación 4.5 G en la ciudad de Trujillo en septiembre 2018

El presente estudio se trata de una investigación aplicada en el Networking el cual analizará el modelo de procesos en una nueva estación 4.5G para posteriormente usando el enfoque BPM plantear un modelo propio que mejore el indicador throughput en una nueva estación 4.5G en la ciudad de Trujillo en el mes de septiembre del año 2018. Se tendrán para el estudio una estación 4.5G como control y otra como experimental sobre la cual se implementará el modelo basado en BPM de manera que se puedan comparar las mediciones de throughput de ambas en las cuatro primeras horas de activación validando lo planteado en la hipótesis. Dicho estudio aporta un modelo de elaboración propia en el radio access network (RAN) para el sector de las telecomunicaciones, el cual no ha sido tratado en estudios previos por otros investigadores.The present study is about an applied research in the Networking which will analyze the process model in a new 4.5G station and then using the BPM approach to propose an own model that improves the throughput indicator in a new 4.5G station in the city of Trujillo in the month of September of the year 2018. A 4.5G station will be considered as a control and another as an experimental one on which the BPM-based model will be implemented, so that the throughput measurements of both can be compared in the first four hours of activation, validating what was proposed in the hypothesis. . This study provides a model of its own development in the radio access network (RAN) for the telecommunications sector, which has not been addressed in previous studies by other researchers.Tesi

Algunas claves para el análisis de procesos de negociación

El presente artículo se centra en los procesos de conformación de los actores políticos involucrados en negociaciones internas o internacionales y en sus relaciones de largo plazo con otros actores. Se presta especial atención al manejo de la complejidad que caracteriza la generación de políticas en sistemas dinámicos, a cómo se desarrollan estrategias consistentes con los objetivos buscados en el marco del juego político que es toda negociación y a la influencia de los modelos de análisis y categorías conceptuales de cada actor sobre su accionaren procesos de negociación. En el trabajo se utilizan como marco teórico los aportes de la teoría de la negociación desarrollada por Harvard desde la década de los ochenta, así como las contribuciones de la teoría de juegos y las de la teoría de la cooperación.Como ejes articuladores de toda negociación se desarrollan los niveles de ésta y los actores involucrados, el número y la composición de los actores, la matriz de pagos del juego, el número de metas a alcanzar por los actores, y los sistemas de información utilizados en el proceso de negociación

We demonstrate that the vector obtained by Kernel Quadratic Programming Feature Selection is equivalent to the Kernel Fisher vector and, therefore, a new interpretation of the Kernel Fisher discriminant analysis is given which provides some computational advantages for highly unbalanced datasets.I.R.-L. is supported by an FPU grant from Universidad Autónoma de Madrid, and partially supported by the Universidad Autónoma de Madrid-IIC Chair and TIN 2010-21575-C02-01.

Hierarchical linear support vector machine

This is the author’s version of a work that was accepted for publication in Pattern Recognition. Changes resulting from the publishing process, such as peer review, editing, corrections, structural formatting, and other quality control mechanisms may not be reflected in this document. Changes may have been made to this work since it was submitted for publication. A definitive version was subsequently published in Pattern Recognition, Vol. 45, Iss. 12, (2012) DOI: 10.1016/j.patcog.2012.06.002The increasing size and dimensionality of real-world datasets make it necessary to design efficient algorithms not only in the training process but also in the prediction phase. In applications such as credit card fraud detection, the classifier needs to predict an event in 10 ms at most. In these environments the speed of the prediction constraints heavily outweighs the training costs. We propose a new classification method, called a Hierarchical Linear Support Vector Machine (H-LSVM), based on the construction of an oblique decision tree in which the node split is obtained as a Linear Support Vector Machine. Although other methods have been proposed to break the data space down in subregions to speed up Support Vector Machines, the H-LSVM algorithm represents a very simple and efficient model in training but mainly in prediction for large-scale datasets. Only a few hyperplanes need to be evaluated in the prediction step, no kernel computation is required and the tree structure makes parallelization possible. In experiments with medium and large datasets, the H-LSVM reduces the prediction cost considerably while achieving classification results closer to the non-linear SVM than that of the linear case.The authors would like to thank the anonymous reviewers for their comments that help improve the manuscript.

Multi-task Implementation for Image Reconstruction of an AER Communication

Address-Event-Representation (AER) is a communication protocol for transferring spikes between bio-inspired chips. Such systems may consist of a hierarchical structure with several chips that transmit spikes among them in real time, while performing some processing. There exist several AER tools to help in developing and testing AER based systems. These tools require the use of a computer to allow the processing of the event information, reaching very high bandwidth at the AER communication level. We propose to use an embedded platform based on multi-task operating system to allow both, the AER communication and the AER processing without a laptop or a computer. We have connected and programmed a Gumstix computer to process Address- Event information and measured the performance referred to the previous AER tools solutions. In this paper, we present and study the performance of a new philosophy of a frame-grabber AER tool based on a multi-task environment, composed by the Intel XScale processor governed by an embedded GNU/Linux system.Ministerio de Ciencia e Innovación TEC2006-11730-C03-0

En los bordes del poder mundial: Brasil a comienzos del siglo XXI

This article analyzes Brasil’s position in the international system at present, when the system has been reshaped by the weakening of regional actors such as the European Union or Brazil itself. Three levels of analysis are considered: the international order, the regions with ongoing integration processes and the national State. With regards to the Brazilian case the article studies the recent domestic changes and their impact on the country’s foreign policy, as well as the estrangement from South America y rapprochement with United States as a global actor, with Panamerican positions that Brazil had not assumed during several decades. Finally, the article builds five prospective scenarios and concludes that in the near future Brazil does not have many chances to become a powerful actor with strategic importance in the world system. El presente artículo analiza la posición de Brasil en el escenario internacional promediando la segunda década del siglo XXI, escenario que ha resultado reconfigurado por la pérdida de peso específico de actores regionales como la Unión Europea y el propio Brasil. El trabajo utiliza tres niveles de análisis: el sistema internacional, las regiones donde se dan procesos de integración y los procesos internos de los Estados-nación. En particular, en el caso de Brasil se consideran los recientes cambios políticos internos y su impacto sobre su política exterior, y también su distanciamiento de Sudamérica en el plano regional y su reorientación hacia los Estados Unidos en lo global. Finalmente, se plantea el poco espacio que Brasil tiene en un futuro próximo entre los países que se ubican en la cúspide del poder mundial aún en los escenarios prospectivos le que serían más favorables
