El eco de los presos: los libertarios en la cárceles franquistas y la solidaridad desde fuera de la prisión, 1936-1963

Esta tesis doctoral explora las vivencias colectivas, las actitudes e iniciativas de los presos anarquistas desde la victoria franquista hasta los años sesenta. El estudio ha tenido como doble objetivo reconstruir una esfera de experiencia a la que los propios libertarios otorgaron importancia en sus relatos y memorias sobre la lucha contra el régimen, y ubicar tal experiencia colectiva en el marco más amplio de la historia de la implantación de la dictadura y del declive del anarquismo español. Las aproximaciones a la historia de los presos políticos durante el franquismo no han tenido en cuenta, por lo general, el modo en que la filiación ideológica, así como las redes e identidades colectivas de los reclusos mediaron en la construcción de su experiencia. Por otra parte, la historiografía del anarquismo de posguerra se ha centrado en el estudio de las formas de lucha clandestinas y el devenir del movimiento en el exilio, pero apenas ha considerado la realidad vivida por los miles de militantes dentro de las cárceles. Este estudio parte de una primera noción, según la cual, en las prisiones de las dos primeras décadas de la dictadura, a pesar de los esfuerzos del régimen por arrancar el más mínimo brote de organización de la oposición, los presos políticos protagonizaron diversos episodios de resistencia y procesos de reconstrucción de sus vínculos identitarios y estructuras organizativas. Esto hizo que militantes de los diversos ámbitos ideológicos se organizaran aparte, constituyendo comunidades diferenciadas entre sí dentro las cárceles. Además, las prisiones y los activistas detenidos constituyeron constantemente un elemento con el cual aquellos todavía en libertad se debieron confrontar necesariamente, porque casi todos los exponentes más importantes estaban encarcelados. Dicho esto, a partir del análisis de diversos tipos de documentos personales generados por los propios anarquistas (autobiografías, cartas y entrevistas) y de fuentes oficiales franquistas, hemos reconstruido la formación –sin duda, fragmentaria e irregular- del sujeto “preso libertario” y sus significados, hemos examinado sus respuestas al entorno carcelario franquista, y puesto esas realidades en relación con la oposición antifranquista de primera época, tanto del interior como del exilio...

Carbon assimilation, herbage accumulation, nutritive value, and grazing efficiency of Mulato II brachiariagrass under continuous stocking

Grazed pastures are the backbone of the Brazilian livestock industry and grasses of the genus Brachiaria (syn. Urochloa) are some of most used tropical forages in the country. Although the dependence on the forage resource is high, grazing management is often empirical and based on broad and non-specific guidelines. Mulato II brachiariagrass (Convert HD 364, Dow AgroSciences, São Paulo, Brazil) (B. brizantha × B. ruziziensis × B. decumbens), a new Brachiaria hybrid, was released as an option for a broad range of environmental conditions. There is no scientific information on specific management practices for Mulato II under continuous stocking in Brazil. The objectives of this research were to describe and explain variations in carbon assimilation, herbage accumulation (HA), plant-part accumulation, nutritive value, and grazing efficiency (GE) of Mulato II brachiariagrass as affected by canopy height and growth rate, the latter imposed by N fertilization rate, under continuous stocking. An experiment was carried out in Piracicaba, SP, Brazil, during two summer grazing seasons. The experimental design was a randomized complete block, with a 3 x 2 factorial arrangement, corresponding to three steady-state canopy heights (10, 25 and 40 cm) maintained by mimicked continuous stocking and two growth rates (imposed as 50 and 250 kg N ha-1 yr-1), with three replications. There were no height × N rate interactions for most of the responses studied. The HA of Mulato II increased linearly (8640 to 13400 kg DM ha-1 yr-1), the in vitro digestible organic matter (IVDOM) decreased linearly (652 to 586 g kg-1), and the GE decreased (65 to 44%) as canopy height increased. Thus, although GE and IVDOM were greatest at 10 cm height, HA was 36% less for the 10- than for the 40-cm height. The leaf carbon assimilation was greater for the shortest canopy (10 cm), but canopy assimilation was less than in taller canopies, likely a result of less leaf area index (LAI). The reductions in HA, plant-part accumulation, and LAI, were not associated with other signs of stand deterioration. Leaf was the main plant-part accumulated, at a rate that increased from 70 to 100 kg DM ha-1 d-1 as canopy height increased from 10 to 40 cm. Mulato II was less productive (7940 vs. 13380 kg ha-1 yr-1) and had lesser IVDOM (581 vs. 652 g kg-1) at the lower N rate. The increase in N rate affected plant growth, increasing carbon assimilation, LAI, rates of plant-part accumulation (leaf, stem, and dead), and HA. The results indicate that the increase in the rate of dead material accumulation due to more N applied is a result of overall increase in the accumulation rates of all plant-parts. Taller canopies (25 or 40 cm) are advantageous for herbage accumulation of Mulato II, but nutritive value and GE was greater for 25 cm, suggesting that maintaining ∼25-cm canopy height is optimal for continuously stocked Mulato II.

Análise de métodos de avaliação de eco eficiência.

Para que a sustentabilidade seja gerenciada e praticada de maneira efetiva, ela deve ser mensurada, utilizando-se de métodos de avaliação da sustentabilidade. Estão disponíveis diferentes métodos de avaliação, que geralmente reduzem o resultado desse levantamento à indicadores de desempenho ambiental, econômico e social (POPEA; ANNANDALE; MORISON-SAUNDERSB, 2004). Uma das denominações mais bem aceitas e difundidas para a conjunção da dimensão ambiental e econômica é conhecida por avaliação de eco eficiência (AEE). Eco eficiência é o \"aspecto da sustentabilidade que relaciona o desempenho ambiental de um sistema de produto ao valor do sistema de produto\" (ISO, 2012). Estão disponíveis diferentes métodos de AEE, porém sem evidência das suas semelhanças e particularidades e como essas características influenciam na escolha do método mais adequado de AEE em relação às potenciais aplicações O objetivo desta pesquisa é, portanto, analisar e indicar os tipos de métodos de avaliação de eco eficiência (AEE) mais adequados para ações gerenciais nas quais caibam tais abordagens. Foram selecionados onze métodos de AEE, a partir do estabelecimento de critérios de caracterização desses métodos, a saber: BASF, Bayer, EcoWater, Hahn et al., Kuosmanen e Kortelainen, MIPS, NRTEE, UN ESCAP, UN, TU Delft, e WBCSD. Identificaram-se, ainda, quatro potenciais aplicações: (i) Monitoramento de processo com vistas à melhoria contínua; (ii) Selecção e classificação de produtos; (iii) Atendimento a requisitos legais e outros requisitos; e, (iv) Marketing, rotulagem de produtos e comunicação ambiental. A partir dos elementos metodológicos estabelecidos pela norma ISSO 14045 (2012) e do conhecimento obtido dos métodos de AEE, determinaram-se quatro requisitos pelos quais os métodos e os potenciais aplicações foram avaliados: (i) Tipo de indicador de desempenho ambiental; (ii) Tipo de indicador de valor de sistema de produto; (iii) Abrangência de aplicação; e, (iv) Tipo de indicador de eco eficiência. Aplicando-se estes requisitos nos métodos de AEE e nos potenciais usos, concluiu-se que quanto à aplicações em termos de monitoramento de processos com vistas à melhoria continua os métodos de AEE recomendados foram Bayer, NRTEE, WBCSD e UN. Para situações de seleção e classificação de produtos os métodos BASF, EcoWater, Kuosmanen e Kortelainen, MIPS, Hahn et al., TU Delft, UN ESCAP e UN demonstraram ter boa aderência. No que se refere a usos voltados ao atendimento de requisitos legais e/ou de outras naturezas, os métodos NRTEE, WBCSD e UN são os mais indicados. Em aplicações de marketing, rotulagem e comunicação foram indicados os métodos BASF, EcoWater e MIPS. Finalmente, concluiu-se que, para a escolha adequada da metodologia para uma AEE, conhecimento prévio das características de cada abordagem é necessário.

Drought and grazing combined: Contrasting shifts in plant interactions at species pair and community level

The combined effects of drought stress and grazing pressure on shaping plant–plant interactions are still poorly understood, while this combination is common in arid ecosystems. In this study we assessed the relative effect of grazing pressure and slope aspect (drought stress) on vegetation cover and soil functioning in semi-arid Mediterranean grassland–shrublands in southeastern Spain. Moreover, we linked these two stress factors to plant co-occurrence patterns at species-pair and community levels, by performing C-score analyses. Vegetation cover and soil functioning decreased with higher grazing pressure and more south-facing (drier) slopes. At the community level, plants at south-facing slopes were negatively associated at no grazing but positively associated at low grazing pressure and randomly associated at high grazing pressure. At north-facing slopes, grazing did not result in a shift in the direction of the association. In contrast, analysis of pairwise species co-occurrence patterns showed that the dominant species Stipa tenacissima and Anthyllis cytisoides shifted from excluding each other to co-occurring with increasing grazing pressure at north-facing slopes. Our findings highlight that for improved understanding of plant interactions along stress gradients, interactions between species pairs and interactions at the community level should be assessed, as these may reveal contrasting results.

La evaluación de los aprendizajes en los sMOOC. Estudio de caso en el Proyecto Europeo ECO

El siguiente artículo hace una reflexión crítica sobre los MOOC, prestando especial atención al análisis de los nuevos sistemas de evaluación; en concreto, el método peer to peer, y cómo esto afecta al rol de docentes y estudiantes. El estudio se ha llevado a cabo tomando como referencia dos sMOOC liderados por el Proyecto Europeo ECO (Elearning, Communication and Open-data: Massive Mobile, Ubiquitous and Open Learning). Los resultados que se presentan han sido analizados desde una perspectiva cuantitativa, utilizando como muestra a los miembros de la comunidad de aprendizaje que han participado en ambos cursos. A través de la utilización de un cuestionario se ha podido conocer cómo han valorado su experiencia formativa y su grado de satisfacción. La mitad de los sujetos encuestados ha considerado adecuado y justo el nuevo sistema evaluativo, sin embargo existe otra mitad que lo considera injusto y que tiene lagunas. Se ha abordado la evaluación como una parte intrínseca del proceso educativo y por ello se ha enfatizado en aspectos como el empoderamiento del alumnado, la cultura de la participación y la interacción social, conceptos que nos acercan a nuevos modelos de aprendizaje que potencian el intelecto colectivo y dejan atrás sistemas transmisivos de conocimiento.

European Energy and Industrial Policy Realigned: Risk or Opportunity for EU Eco-Innovation Strategy? IES Policy Brief Issue 2014/03/February 2014

Summary. Europe’s eco-innovation strategy fuses industrial, energy and environmental policy together in a concept for sustainable economic growth in the 21st century. The latest debate about high energy prices and their impact on energy-intensive industry shows, however, that the emphasis among the three policies has shifted over the years. Some adjustments are therefore necessary in order to reduce evolving inconsistencies. This Policy Brief describes the different dimensions of the EU’s industrial policy, and assesses the options available to policy-makers to increase the competitiveness of energy-intensive sectors without compromising the eco-innovation and sustainability agenda. If several key principles of the European sustainability agenda remain unchanged, strategic development is possible.

Measuring progress in eco-innovation. CEPS Working Document No. 409/June 2015

Eco-innovation has been identified as one of the key drivers of change that need to be harnessed for a sustainable future. Given the complexity of eco-innovation as a concept, there are various challenges to measuring its progress. This paper briefly explores the evolution of the concept of eco-innovation and emphasises its role in the EU 2020 strategy. It then provides an overview of the different measurement approaches and challenges associated with identifying and using indicators for measuring progress in eco-innovation. Within this context, the paper describes the added value and key features of the www.measuring-progress.eu web tool, which aims to improve the way in which policy-makers and others involved in the policy process can access, understand and use indicators for green economy and eco-innovation. The web tool was developed on the basis of a systematic overview by the NETGREEN research team of the large and fragmented body of work in the field of green economy indicators. The paper concludes with a number of messages for policy-makers in the field of the green economy.
