De aquí a allá, de ayer a hoy : Posmemoria y cine documental en la España y Argentina contemporáneas

Tanto en el panorama cinematográfico español como en el argentino, varios son los títulos que desde el ámbito no sólo de la ficción, sino también del documental, han pretendido dar una visión de lo que sucedió durante la guerra civil y el franquismo y, en el caso del país latinoamericano, de la última dictadura militar encabezada por Jorge Rafael Videla. Dentro de este grupúsculo de películas, en la última década se ha producido un nada despreciable número de películas documentales (Nadar, Entre el dictador y yo, Muerte en El Valle, El muro de los olvidados, Cosas raras que pasaban entonces, Pepe el andaluz o Tierra encima, en España; o Los Rubios, M, En memoria de los pájaros, Encontrando a Víctor, Papá Iván o La fe del volcán, en Argentina) firmadas por la generación siguiente o subsiguiente a la de quienes fueron víctimas directas o indirectas de la tortura, el exilio, la represión y la falta de libertades impuestas por sendos regímenes totalitarios. Se trata, en todos los casos, de jóvenes cineastas y videastas que se acercan a un pasado que no recuerdan pero al cual necesitan interrogar de manera imperiosa para poder definirse en tanto que sujetos políticos. El artículo que presentamos pretende acercarse a dos corpus cinematográficos fraguados en países geográficamente muy distantes pero realizados bajo una mirada muy similar: aquella que se arroja desde la 'posmemoria', esto es, desde una distancia generacional respecto a los hechos históricos evocados que proporciona a estas cintas una voz políticamente más crítica pero no por ello menos intimista y autobiográfica que la que puede ostentar el superviviente o el testigo directo de los hechos. El propósito último de nuestro análisis es el de poder dilucidar los puntos de convergencia y de divergencia entre un conjunto de producciones documentales que si bien creemos que aboga por la transmisión de la memoria entre generaciones y su continuidad en el futuro, implica la presencia, por su misma idiosincrasia, de vacíos, silencios, recreaciones y, en definitiva, (auto)ficciones que, normalmente desde la primera persona, dan fe de unos sujetos fracturados por los traumáticos y complejos orígenes de sus respectivas genealogías familiares

Territorio y extensión universitaria. Una experiencia de organización social en el Parque Pereyra Iraola

El trabajo que aquí se presenta recupera la experiencia de organización social y extensión que universitarios, militantes y técnicos rurales viene desarrollando en el Parque Pereyra Iraola desde el año 2001 junto a un grupo de 40 familias, como una estrategia de respuesta a la crisis. Se propone entender el proceso de transformación en la toma de posición territorial de los quinteros como un sistema de relaciones complejo entre la posición social de los productores, la irregularidad en la forma de tenencia de la tierra, la resistencia espontánea al desalojo, el posicionamiento de los extensionistas rurales que brindan asistencia técnica y la estrategia de conversión a la producción sin agrotóxicos.

Modalidades de la diversidad en los vínculos familiares

Se presenta una síntesis del nuevo proyecto de investigación, en el que se propone indagar las Modalidades de la diversidad en el ejercicio de la parentalidad y en la pareja , en dos campos de problemáticas. Una refiere a la diversidad en relación con las múltiples formas que adquieren hoy las configuraciones vinculares familiares. La otra a la diversidad en relación con la conformación sexual de la pareja. Se desarrollan los núcleos conceptuales con que se abordarán dichas problemáticas: origen y transformaciones del patriarcado ; sexualidad y diversidad ; complejización y ampliación de los conceptos del marco teórico que se vienen utilizando desde las anteriores investigaciones: concepto de familia (organización y aspectos estructurales), principios de permanencia y cambio , vínculo , diversidad y parejas parentales del mismo sexo. De investigaciones anteriores se evalúa que persiste la representación de la madre como eje central de la crianza y que el reparto del poder entre madres y padres en la familia y entre varones y mujeres en la sociedad surge con vacilaciones y ambivalencias. Orientará la presente investigación la indagación sobre los modos actuales de expresión de estas representaciones, en familias de organización y configuración de la pareja no convencionales. El análisis de sus transformaciones posibilitará dilucidar su relación con nuevas formas de lazo familiar que den cuenta de la diversidad

Careers guidance: an international perspective

The rationales for comparative studies of guidance systems are outlined. The key differences between guidance systems in different countries can be related to stage of economic development, to the political system, to social and cultural factors, to the education and training system, and to professional and organisational structures. The competing pressures towards convergence and divergence between guidance systems are explored.

La diversidad familiar en situaciones de exclusión social. Resultados y reflexiones sobre actividades de investigación, formación y transferencia de conocimientos

El presente artículo se propone caracterizar las configuraciones familiares que habitan en contextos de exclusión social; aportar conceptualizaciones sobre sus modos de funcionamiento a través de la sistematización de los datos recogidos y destacar los efectos formativos que las prácticas interdisciplinarias barriales con esas familias, van produciendo en los psicólogos recién graduados, a través de una tarea de transferencia del enfoque sobre la diversidad tanto en el interior de las investigaciones como a partir de las intervenciones realizadas con las familias en las tareas de incorporados al Programa de Extensión. Asimismo, nos ha interesado poder efectuar una tarea de transferencia del enfoque sobre la diversidad en la formación de los profesionales jóvenes, tanto en el interior de las investigaciones como en el de las intervenciones realizadas con familias en las tareas de extensión. Este trabajo surge de resultados y reflexiones provenientes de tres fuentes: de lo producido en el marco de una Beca de iniciación a la Investigación; de las investigaciones sobre parentalidad, que desde el año 2001 venimos realizando en la Cátedra de Psicología Evolutiva II y del trabajo interdisciplinario con familias asistidas psicológicamente en el interior del Programa de Extensión Universitaria ?Consultorios Jurídicos Gratuitos?, asentados en doce barrios suburbanos de la ciudad de La Plata (convenio entre la Facultad de Ciencias Jurídicas y Sociales y la Facultad de Psicología, U.N.L.P.) A partir de una metodología cualitativa, con participación interdisciplinaria, los resultados obtenidos han permitido por un lado arribar a la caracterización y conceptualizaciones propuestas acerca de las familias incluidas y al mismo tiempo precisar los beneficios que para la formación de estudiantes avanzados y jóvenes graduados trae aparejado el trabajo que articula actividades de investigación y extensión

Composition of bottom sediments from Core SO201-2-101, Shirshov Ridge, Bering Sea

Analysis of lithology, grain-size composition, clay minerals, and geochemistry of Upper Pleistocene bottom sediments from the submarine Shirshov Ridge (Bering Sea) showed that the Yukon-Tanana terrane of the Central Alaska was main source area of the sediments. Sedimentary material was transported by the Yukon River through Beringia up to the shelf break, where they were entrained by a strong north-west sea current. Lithological data revealed several pulses of ice-rafted debris deposition roughly synchronous with Heinrich events and periods of weaker bottom current intensity. Based on geochemical results we distinguished intervals of an increase in paleoproductivity and extension of the oxygen minimum zone. Our results suggest that there were three stages of deposition driven by glacioeustatic sea-level fluctuations and glacial cycles in Alaska.

Case Study of Applied LIP Approach/Activities in the Philippines The Training Services Enhancement Project for Rural Life Improvement (TSEP-RLI) Experience

TSEP-RLI was a technical cooperation project jointly conducted by GOP thru DA-Agricultural Training Institute (ATI) and GOJ thru JICA aimed at institutionalizing the training program for Rural Life Improvement (RLI) at the (ATI). As expected, farmers, fisherfolk, women, youth and extension agents were provided with efficient and effective training services from ATI leading to the improvement of quality of life in the rural areas through efforts of human resource development. The ATI- Bohol was chosen as the model center where participatory trials and various activities of the project were undertaken for five years. These activities were participatory surveys and data collection of on-farm and off-farm productive activities; planning workshop for RLI; feedbacking of survey results and action plans to the community and the Local Government Units (LGUs), and signing of Memorandum of Agreement between the Project and participating LGUs. The above activities were done to facilitate the planning and development of most effective and necessary rural life improvement activities, to confirm the willingness of the people to support and participate and to formalize the partnership between the Project and the LGUs. Since the concept of rural life covers a vast range of activities, a consensus had been reached that the total aspects of rural life be grasped in three spheres, namely, Production & Livelihood (P/L), Rural Living Condition (RLC) and Community Environment (C/E). The RLI for Ubi (Yam) Growers was one of the pilot activities undertaken in two pilot barangays and the target beneficiaries were members of the Rural Improvement Club (RIC- a group of organized women) with the LGU of the Municipality of Corella as the implementing partner. During the planning workshop, the barangay residents articulated their desire to promote production and processing of ubi (sphere on P/L - as the entry point), lack of nutritious food was one of the identified problem (sphere on RLC- expansion point) and environmental degradation such as deforestation, and soil erosion was another problem articulated by the community people (sphere on C/E- expansion point). Major activities that were undertaken namely, Ubi cooking contest, cooking/processing seminar, training courses on entrepreneurial development, ubi production and storage technology, packaging and product design, human resource development and simplified bookkeeping motivated the beneficiaries as well as developed and enhanced their skills & capabilities while strengthening their associations. Their participation to the 5 ubi festivals and other related activities had brought some impacts on their economic and rural life improvement activities. The seven principles of TSEP-RLI include the participatory process, holistic approach, dialogical approach, bottom -up training needs assessment, demand-driven approach, cost sharing approach and collaborative implementation with other agencies including LGUs and the community.

Efficient Model-based 3D Tracking by Using Direct Image Registration

This thesis deals with the problem of efficiently tracking 3D objects in sequences of images. We tackle the efficient 3D tracking problem by using direct image registration. This problem is posed as an iterative optimization procedure that minimizes a brightness error norm. We review the most popular iterative methods for image registration in the literature, turning our attention to those algorithms that use efficient optimization techniques. Two forms of efficient registration algorithms are investigated. The first type comprises the additive registration algorithms: these algorithms incrementally compute the motion parameters by linearly approximating the brightness error function. We centre our attention on Hager and Belhumeur’s factorization-based algorithm for image registration. We propose a fundamental requirement that factorization-based algorithms must satisfy to guarantee good convergence, and introduce a systematic procedure that automatically computes the factorization. Finally, we also bring out two warp functions to register rigid and nonrigid 3D targets that satisfy the requirement. The second type comprises the compositional registration algorithms, where the brightness function error is written by using function composition. We study the current approaches to compositional image alignment, and we emphasize the importance of the Inverse Compositional method, which is known to be the most efficient image registration algorithm. We introduce a new algorithm, the Efficient Forward Compositional image registration: this algorithm avoids the necessity of inverting the warping function, and provides a new interpretation of the working mechanisms of the inverse compositional alignment. By using this information, we propose two fundamental requirements that guarantee the convergence of compositional image registration methods. Finally, we support our claims by using extensive experimental testing with synthetic and real-world data. We propose a distinction between image registration and tracking when using efficient algorithms. We show that, depending whether the fundamental requirements are hold, some efficient algorithms are eligible for image registration but not for tracking.

An approach of the European higher education framework to the management of higher education at university level in Perú

This communication research gives an insight to University Education in Peru and a brief review of the main European documents that deal with the European Higher Education Framework, highlighting the principles upon which it is based, as well as the strategic objectives that it sets forth and the tools to achieve them. The purpose of this process is to adapt our university education management in Peru to the EEES, seeking to identify the limitations and constraints faced with regard to the keys of European convergence and the means or instruments that we have in order to attain convergence in Peru.

An approach to operational modal analysis using the expectation maximization algorithm

This paper presents the Expectation Maximization algorithm (EM) applied to operational modal analysis of structures. The EM algorithm is a general-purpose method for maximum likelihood estimation (MLE) that in this work is used to estimate state space models. As it is well known, the MLE enjoys some optimal properties from a statistical point of view, which make it very attractive in practice. However, the EM algorithm has two main drawbacks: its slow convergence and the dependence of the solution on the initial values used. This paper proposes two different strategies to choose initial values for the EM algorithm when used for operational modal analysis: to begin with the parameters estimated by Stochastic Subspace Identification method (SSI) and to start using random points. The effectiveness of the proposed identification method has been evaluated through numerical simulation and measured vibration data in the context of a benchmark problem. Modal parameters (natural frequencies, damping ratios and mode shapes) of the benchmark structure have been estimated using SSI and the EM algorithm. On the whole, the results show that the application of the EM algorithm starting from the solution given by SSI is very useful to identify the vibration modes of a structure, discarding the spurious modes that appear in high order models and discovering other hidden modes. Similar results are obtained using random starting values, although this strategy allows us to analyze the solution of several starting points what overcome the dependence on the initial values used.

A Keyword-driven approach for generating OWL DL conformance test data

The conformance of semantic technologies has to be systematically evaluated to measure and verify the real adherence of these technologies to the Semantic Web standards. Currente valuations of semantic technology conformance are not exhaustive enough and do not directly cover user requirements and use scenarios, which raises the need for a simple, extensible and parameterizable method to generate test data for such evaluations. To address this need, this paper presents a keyword-driven approach for generating ontology language conformance test data that can be used to evaluate semantic technologies, details the definition of a test suite for evaluating OWL DL conformance using this approach,and describes the use and extension of this test suite during the evaluation of some tools.

Improving availability of mobile networks using a cluster routing protocol with redundant cluster head

We show a cluster based routing protocol in order to improve the convergence of the clusters and of the network it is proposed to use a backup cluster head. The use of a event discrete simulator is used for the implementation and the simulation of a hierarchical routing protocol called the Backup Cluster Head Protocol (BCHP). Finally it is shown that the BCHP protocol improves the convergence and availability of the network through a comparative analysis with the Ad Hoc On Demand Distance Vector (AODV)[1] routing protocol and Cluster Based Routing Protocol (CBRP)[2]

Consulta on-line basada en corpus de construcciones con preposición en el texto técnico en inglés y su traducción al español

Basándonos en la recopilación inicial de preposiciones, locuciones preposicionales, términos con preposición dependiente y phrasal verbs utilizados en el texto técnico realizada en otros proyectos anteriores del Departamento de Lingüística Aplicada a la Ciencia y a la Tecnología, el objetivo de este trabajo es completar, organizar, actualizar y dar visibilidad a esta información inicial. Tras realizar un proceso exhaustivo de verificación, unificación, clasificación y ampliación de la información existente, en caso necesario, el listado resultante se utiliza para elaborar un glosario de términos con preposición. El objetivo final de este proyecto es que este glosario esté a disposición de los usuarios, a través de una consulta on-line, en la página del ILLLab (http://illlab.euitt.upm.es/wordpress/), dependiente del Departamento de Lingüística Aplicada a la Ciencia y a la Tecnología. Para incluir en el glosario ejemplos actualizados de textos técnicos, se ha recopilado un corpus lingüístico de textos técnicos, tomando como base diferentes números de la revista IEEE Spectrum, en su edición digital, publicados entre los años 2009 y 2012. El objetivo de esta recopilación es la de ofrecer al consultante diferentes ejemplos de uso en el texto técnico de los distintos términos con preposición que componen el glosario, de manera que pueda acceder de manera rápida y sencilla a ejemplos de uso real de los términos que está buscando, con objeto de clarificar aspectos relacionados con su uso o, en su caso, facilitar su aprendizaje. Toda esta información, tanto el listado de términos con preposición como las frases pertenecientes al corpus recopilado, se incorpora a una base de datos, alojada dentro de la misma página web del ILLLab. A través de un formulario de consulta, a disposición del usuario en dicha página, se pueden obtener todos los términos recopilados que coincidan con los criterios de búsqueda introducidos. El usuario puede realizar dos tipos de búsqueda principales: por preposición o por término completo. Además, puede elegir una búsqueda global (entre todos los términos que integran el glosario) o parcial (en una sola de las categorías en las que se han dividido los diferentes términos, de acuerdo con su función gramatical). Por último, se presentan unas estadísticas de uso de los términos recopilados dentro de los diferentes textos que integran el corpus lingüístico, de manera que pueda establecerse una relación de los que aparecen con más frecuencia en el texto técnico. ABSTRACT. Based on the initial collection of prepositions, prepositional phrases, dependent prepositions and phrasal verbs used in technical texts collected on previous projects in the Department of Applied Linguistics to Science and Technology, the aim of this project is to improve, organize, update and provide visibility to this initial information. Following a process of verification, unification, classification and extension of existing information, if necessary, a glossary of terms with preposition is built. The ultimate objective of this project is to make this glossary available to users through an online consultation in the ILLLab webpage (http://illlab.euitt.upm.es/wordpress/). The administration of tis webpage depends of the Department of Applied Linguistics in Science and Technology. A linguistic corpus of technical texts has been compiled, based on different numbers of the IEEE Spectrum magazine, in its online edition, published between the years 2009 and 2012. The aim of this collection is to provide different examples of use in the technical text for the terms included in the glossary, so that examples of the actual use of the terms consulted can be easily and quickly accessed, in order to clarify doubts regarding their meaning or translation into Spanish and facilitate learning. All this information, both the list of terms with prepositional phrases as well as the corpus developed, is incorporated in a database. Through a searching form, the ILLLab's user may obtain all the terms matching the search criteria entered. The user can perform two types of main search: by preposition or by full term. Additionally, a global search can be selected (including all terms included in the glossary) or a partial one (including only one of the glossary's categories). Finally, some statistics of use are presented according to the various texts included in the corpus, so a relation of the most frequent prepositions in the technical text can be established.

Two design methods for radial line slot antennas with arbitrary or beam pattern

Two design procedures for Radial Line Slot Antennas (RLSAs) with circular polarization and either maximum gain or an arbitrary shaped pattern are proposed. Firstly, a method to design a RLSA with any desired pattern is presented. It is based on an optimization algorithm and some measures to ensure its fast convergence and stability need to be taken. Secondly, a fast technique to calculate the length and the position of every slot in a high gain RLSA with uniform field distribution is described. Both procedures are vali dated with the design of three antennas with different characteristics.

Urban agriculture in the new framework of green cities.

Urban Agriculture was a common practice in the old times. However after a period of low interest by urban population there is a movement of renaissance of urban agriculture especially in the new megalopolis. It is important to understand the role of UA in the new framework, and the interface of urban and rural agricultures, with their comparative advantages. Thus, we describe the impact of UA in several scenarios: political, socioeconomic and environmental. As a consequence several actions should be developed for improving the situation, with the stimulus to UA: urban planning, food value chain, appropriate technology, education and extension services, entertainment and leisure, selection of botanic varieties and agrochemical inputs, design and landscape and good farming practices. As a complement, there is an analysis of the Urban Greening Value Organization in our society. In the paper there is a description of the situation of urban agriculture in Spain (located mainly in roofs, walls, indoor and ground places) the existence of local regulations, barriers and opportunities in the new situation. Due to the social dimension of urban agriculture there are some comments about the role of the more significant stakeholders, and the goals and the structure of the neighbor communities.
