Abstract This article presents the increasing demands over the Brazilian Ministry of Foreign Affairs (Itamaraty) for opening its doors to other actors. This discussion will be followed by relevant theoretical and methodological analysis. We will defend the need to overcome problems related to: 1) conceptual vagueness about what the concept of participation means; 2) lack of clarity in the baseline to which comparisons are made; 3) fragile empirical basis; 4) limitations on the use of sources; and 5) how to understand the impact exerted by systemic forces.

Video coding technologies have played a major role in the explosion of large market digital video applications and services. In this context, the very popular MPEG-x and H-26x video coding standards adopted a predictive coding paradigm, where complex encoders exploit the data redundancy and irrelevancy to 'control' much simpler decoders. This codec paradigm fits well applications and services such as digital television and video storage where the decoder complexity is critical, but does not match well the requirements of emerging applications such as visual sensor networks where the encoder complexity is more critical. The Slepian Wolf and Wyner-Ziv theorems brought the possibility to develop the so-called Wyner-Ziv video codecs, following a different coding paradigm where it is the task of the decoder, and not anymore of the encoder, to (fully or partly) exploit the video redundancy. Theoretically, Wyner-Ziv video coding does not incur in any compression performance penalty regarding the more traditional predictive coding paradigm (at least for certain conditions). In the context of Wyner-Ziv video codecs, the so-called side information, which is a decoder estimate of the original frame to code, plays a critical role in the overall compression performance. For this reason, much research effort has been invested in the past decade to develop increasingly more efficient side information creation methods. This paper has the main objective to review and evaluate the available side information methods after proposing a classification taxonomy to guide this review, allowing to achieve more solid conclusions and better identify the next relevant research challenges. After classifying the side information creation methods into four classes, notably guess, try, hint and learn, the review of the most important techniques in each class and the evaluation of some of them leads to the important conclusion that the side information creation methods provide better rate-distortion (RD) performance depending on the amount of temporal correlation in each video sequence. It became also clear that the best available Wyner-Ziv video coding solutions are almost systematically based on the learn approach. The best solutions are already able to systematically outperform the H.264/AVC Intra, and also the H.264/AVC zero-motion standard solutions for specific types of content. (C) 2013 Elsevier B.V.

En el trabajo se sistematiza la información semántica a fin de que ella sea la articuladora y eje de otros contenidos abordados en la enseñanza de la lengua materna. Así, en primer lugar se sistematizarán conceptos y perspectivas semánticas, para luego establecer relaciones con otros niveles lingüísticos, como lo son la Morfología y la Sintaxis, sin descuidar los aportes de la semántica a los procesos de producción y comprensión textuales. Realizaremos estudios para sistematizar y asignar al contenido un lugar dominante e integrador en el proceso de enseñanza-aprendizaje de la lengua materna, sin pretender desdibujar otras temáticas. Planteamos tareas cuyo punto culminante es la capacitación de docentes y experimentación de las propuestas didácticas en tres cursos de lengua en una institución educativa de la ciudad de Córdoba, cuyo examen, de ser positivo, permitirá la replicación y transferencia de esas prácticas a otras instituciones. Como objetivos generales, destacamos colaborar con la integración de los contenidos que se dictan en Lengua Materna, tomando como eje la naturaleza semántica del lenguaje; contribuir con la formación de los estudiantes en las dimensiones de la comprensión y producción textuales; promover la reflexión y el incremento del caudal léxico -y del lenguaje en general-, por parte de los estudiantes; contribuir con la capacitación y formación de los docentes en las temáticas abordadas, a través de acciones concretas; corroborar que la formación de los alumnos podrá tornarse más significativa en la medida en que se trabajen 'formas' lingüísticas atravesadas por contenidos. El marco teórico está constituido por los aportes de diferentes líneas, los que, compatibilizados, permitirán acceder a un abordaje integral del 'contenido' lingüístico. Más precisamente, consideramos las conceptualizaciones de autores tales como Coseriu (1986) para la delimitación semántica, sus conceptos y operaciones, al que completamos con la perspectiva de Lyons (1986, 1997); para las relaciones entre Morfología, seguimos a Ramírez Sáinz (2008) ; el vínculo sintaxis- semántica será abordado desde la perspectiva de la Gramática Generativa (Demonte,V. 1991; D'Introno, 2001; Fernández Lagunilla, M y Anula Rebollo,A, 1995; los aportes de la comprensión serán considerados desde De Beaugrande-Dresller (1997). Otros autores de referencia son Lakoff y Jhonsson (1998).

Se hace una critica al cambio de orientación dado a la enseñanza de la geografía desde 1990 en las escuelas del Reino Unido y de Estados Unidos por parte de los responsables de las políticas educativas. Así, al primar la perspectiva ética de estamateria sobre la investigación de conceptos, ideas y habilidades espaciales en los estudiantes, se socava el valor educativo de la geografía y la libertad de los jóvenes para dar forma al mundo en que viven.

Based on interviews with diplomats from a representative cross-section of nine member states and members of the EEAS itself, the research findings of this EPIN Working Paper confirm long-standing traditions and member state perceptions of cooperation with European institutions. The paper also reveals new aspects of the intergovernmental method of foreign policy shaping and making in the European Union; in particular how different national positions can positively or negatively affect the consolidation of the EEAS and the role of the EU as an international actor. As such, the Working Paper makes an original contribution to the existing literature on one of most discussed actors in the European Union’s post-Lisbon architecture in the domain of EU external action.

Drawing on discussions within a CEPS Task Force on the revised EU emissions trading system, this report provides a comprehensive assessment of the pros and cons of the various measures put forward by different stakeholders to address the level and stability of the price of carbon in the EU. It argues that the European Commission, the member states, the European Parliament and other stakeholders need to give serious consideration to introducing some kind of ‘dynamic’ adjustment provision to address the relatively inelastic supply. The report also suggests that there is a need to improve communication of market-sensitive information, for example by leaving the management of the ETS to a specialised body.
