The political ecology of Jatropha plantations for biodiesel in Tamil Nadu, India

Jatropha curcas is promoted internationally for its presumed agronomic viability in marginal lands, economic returns for small farmers, and lack of competition with food crops. However, empirical results from a study in southern India revealed that Jatropha cultivation, even on agricultural lands, is neither profitable, nor pro-poor. We use a political ecology framework to analyze both the discourse promoting Jatropha cultivation and its empirical consequences. We deconstruct the shaky premises of the dominant discourse of Jatropha as a “pro-poor” and “pro-wasteland” development crop, a discourse that paints a win-win picture between poverty alleviation, natural resource regeneration, and energy security goals. We then draw from field-work on Jatropha plantations in the state of Tamil Nadu to show how Jatropha cultivation favors resource-rich farmers, while possibly reinforcing existing processes of marginalization of small and marginal farmers.

Cap a una escola secundària inclusiva: sabers i experiències de joves en situació d'exclusió

[cat] Aquest projecte revisa la narrativa al voltant del fracàs escolar a partir del desenvolupament de deu històries de joves - set nois i tres noies- de Catalunya en situació d'exclusió escolar. Dins d'aquest marc la recerca s'ha articulat a partir de tres eixos: (1) La realització d'un mapa dels estudis realitzats a Catalunya entorn l'anomenat fracàs escolar, amb la finalitat de situar i contextualitzar les seves narratives dominants. (2) La recerca entorn a les històries biogràfiques d'un grup de joves per explorar alternatives a l'actual crisi internacional de l'escola secundària que es reflecteix, entre d'altres fenòmens, en els elevats índexs d'abandonament d'aquesta etapa educativa per part dels estudiants. (3) La recerca conclou amb una sèrie de consideracions que pretenen contribuir a una narrativa a favor d¿una escola inclusiva per a l'educació secundària que tingui en compte les experiències i sabers d'aquests joves que, per diferents raons, no finalitzen la seva educació bàsica.

La atención a la diversidad cultural en Cataluña: exclusión, segregación e interculturalidad

La diversidad cultural se ha incrementado notablemente en los centros escolares españoles por la llegada de alumnado de origen inmigrado y esto, más los discursos de toma en consideración de las diferencias culturales que han realizado la Unión Europea y las administraciones autonómicas, ha contribuido a la aparición del discurso intercultural. Este artículo presenta la evolución realizada hasta llegar al discurso dominante actual basándose en un trabajo empírico de análisis de documentación editada por la Generalitat de Cataluña sobre política de integración y de escolarización de los inmigrados y entrevistas en profundidad a políticos y técnicos de los diferentes niveles de la administración catalana. De ello se concluye la existencia de tres etapas en la política de integración de los inmigrados en Cataluña: un primer momento de mera observación del fenómeno; una segunda etapa en la que sin abandonar la observación se insiste en la organización vertical y horizontal de la administración para trabajar de forma coordinada un fenómeno que empieza a despertar preocupación; y, una tercera, en la que sin abandonar la necesaria observación y organización, el énfasis se sitúa en la intervención. Estas fases son el marco de lo realizado a nivel educativo donde observamos la dificultad de traducción del discurso intercultural a la práctica cotidiana de los centros escolares, de los noventa, es necesario incrementar los esfuerzos para incorporar al alumnado de origen inmigrado en el dominio de la creencia de que la educación intercultural (en contra de lo que esta implica) es cuestión que deben trabajar los centros con inmigrantes y, ante la presión existente en las aulas (por el incremento del alumnado, la matrícula viva, etc.), el retorno a prácticas potencialmente segregacionistas que nos recuerdan actuaciones implementadas para escolarizar a los gitanos años atrás. Sin negar los avances realizados desde mediados aulas y centros de Cataluña.

Women at home, at school and in the factory. The particular discourse of domesticity done by the Spanish Escuela Economista (1861-1909)

The texts by the Spanish Economist School (second half of the 19th century) contain an assessment of the role of women in the economy and society that is transgressor in front of the prevailing discourse that defended a unique and exclusive role for all women: being at home and a mother. Most members of that economic trend defended female work in the factories, basing themselves on wage arguments and even asked for a professional training for those who in many cases could not even write and read for the fact of being a woman. The texts of those economists give new ideas about the economic and social role of women in a Spain dominated by a discourse that denied the necessity of female work for the working families.

GDAP1-related autosomal dominant Charcot-Marie-Tooth disease: phenotypical and MRI features

El present estudi es basa en la descripció de quatre famílies portadores d’una mateixa mutació puntual (p.R120W) en el gen GDAP1 que segreguen d’una manera autosòmica dominant. Les trobades més rellevants foren:  Els individus afectats varen tindre un començament més tardà i un fenotipus més lleu que les mutacions recessives del gen GDAP-1, però amb una gran variabilitat clínica.  La Resonància Magnètica Muscular va demostrar una afectació selectiva de la musculatura intrínseca del peu i la part distal del panxell. El compartiment posterior superficial de la musculatura del panxell estava més afectat que el compartiment anterolateral.

Political Humor as a confrontational tool against the Syrian regime: A study case: Syria, 15th March 2011 – 15th May 2012

The aim of this working paper is to analyze the inclusion of political humor into the set of actions used by opponents to the Syrian regime during the first year of a state-wide uprising in 2011. The research argues that although political humor has traditionally been seen mainly as a concealed voice against dominant elites, it can nevertheless take a confrontational stance and challenge a regime. In this paper we assess the role of political humor in challenging the legitimacy of the Syrian State through the battle for the signification of events. We will work with a theoretical framework that draws its assumptions from social movements’ studies and cultural studies. Through the assessment of the importance of discourse and the role of ideological domination to a regime we will see how the first year of the Syrian uprising included widespread acts of political humor as part of the strategy against the regime.

Summarization of specialized discourse: the case of medical articles in Spanish

In this article, we present the current state of our work on a linguistically-motivated model for automatic summarization of medical articles in Spanish. The model takes into account the results of an empirical study which reveals that, on the one hand, domain-specific summarization criteria can often be derived from the summaries of domain specialists, and, on the other hand, adequate summarization strategies must be multidimensional, i.e., cover various types of linguistic clues. We take into account the textual, lexical, discursive, syntactic and communicative dimensions. This is novel in the field of summarization. The experiments carried out so far indicate that our model is suitable to provide high quality summarizations.

Discourse, knowledge, power and politics: towards critical epistemic discourse analysis

Although both are fundamental terms in the humanities and social sciences, discourse and knowledge have seldom been explicitly related, and even less so in critical discourse studies. After a brief summary of what we know about these relationships in linguistics, psychology, epistemology and the social sciences, with special emphasis on the role of knowledge in the formation of mental models as a basis for discourse, I examine in more detail how a critical study of discourse and knowledge may be articulated in critical discourse studies. Thus, several areas of critical epistemic discourse analysis are identified, and then applied in a study of Tony Blair’s Iraq speech on March 18, 2003, in which he sought to legitimatize his decision to go to war in Iraq with George Bush. The analysis shows the various modes of how knowledge is managed and manipulated of all levels of discourse of this speech.

Dynamic and Regulated Association of Caveolin with Lipid Bodies: Modulation of Lipid Body Motility and Function by a Dominant Negative Mutant

Caveolins are a crucial component of caveolae but have also been localized to the Golgi complex, and, under some experimental conditions, to lipid bodies (LBs). The physiological relevance and dynamics of LB association remain unclear. We now show that endogenous caveolin-1 and caveolin-2 redistribute to LBs in lipid loaded A431 and FRT cells. Association with LBs is regulated and reversible; removal of fatty acids causes caveolin to rapidly leave the lipid body. We also show by subcellular fractionation, light and electron microscopy that during the first hours of liver regeneration, caveolins show a dramatic redistribution from the cell surface to the newly formed LBs. At later stages of the regeneration process (when LBs are still abundant), the levels of caveolins in LBs decrease dramatically. As a model system to study association of caveolins with LBs we have used brefeldin A (BFA). BFA causes rapid redistribution of endogenous caveolins to LBs and this association was reversed upon BFA washout. Finally, we have used a dominant negative LB-associated caveolin mutant (cavDGV) to study LB formation and to examine its effect on LB function. We now show that the cavDGV mutant inhibits microtubule-dependent LB motility and blocks the reversal of lipid accumulation in LBs.

Psychosocial analysis of ETA's violence legitimation discourse

This study analyses the fundamental components shaping the violence legitimation discourse of ETA (Euskadi Ta Askasuna). With this aim, a category system has been built, which organizes the psychosocial processes identified in previous studies related to violence legitimation. Based on the proposed category system, a content analysis was conducted on 21 statements of ETA, released between 1998 and 2011. An intraobserver and inter-observer reliability analysis reveals high level stability and replicability of the categorization. The results show, firstly, that outgroup components have a predominant presence over ingroup components. Secondly, in the components hierarchy, we observe that elements referring to identity come in first place, followed in similar frequencies by those related to violence representation and the definition of the situation.

Psychosocial analysis of ETA"s violence legitimation discourse

Este artículo analiza los componentes fundamentales que configuran el discurso legitimador de la violencia de ETA (Euskadi Ta Askatasuna). Con este objetivo, se construye un sistema de categorías, el cual organiza los procesos psicosociales identificados en investigaciones previas relacionadas con la legitimación de la violencia. A partir del sistema de categorías propuesto, se realiza un análisis de contenido en 21 comunicados de ETA publicados entre 1998 y 2011. El análisis de fiabilidad intraobservador e interobservador muestra una alta estabilidad y replicabilidad de la categorización. Los resultados muestran, en primer lugar, que los componentes exogrupales son predominantes respecto a los endogrupales. Segundo, en la jerarquización, se observa la preminencia de los elementos referidos a la identidad, seguido por frecuencias similares los relacionados con la representación de la violencia y la definición de la situación.

Differences in the evolutionary history of disease genes affected by dominant or recessive mutations

Background: Global analyses of human disease genes by computational methods have yielded important advances in the understanding of human diseases. Generally these studies have treated the group of disease genes uniformly, thus ignoring the type of disease-causing mutations (dominant or recessive). In this report we present a comprehensive study of the evolutionary history of autosomal disease genes separated by mode of inheritance.Results: We examine differences in protein and coding sequence conservation between dominant and recessive human disease genes. Our analysis shows that disease genes affected by dominant mutations are more conserved than those affected by recessive mutations. This could be a consequence of the fact that recessive mutations remain hidden from selection while heterozygous. Furthermore, we employ functional annotation analysis and investigations into disease severity to support this hypothesis. Conclusion: This study elucidates important differences between dominantly- and recessively-acting disease genes in terms of protein and DNA sequence conservation, paralogy and essentiality. We propose that the division of disease genes by mode of inheritance will enhance both understanding of the disease process and prediction of candidate disease genes in the future.
