Abstract Background Plasmodium vivax is the most widely distributed human malaria, responsible for 70–80 million clinical cases each year and large socio-economical burdens for countries such as Brazil where it is the most prevalent species. Unfortunately, due to the impossibility of growing this parasite in continuous in vitro culture, research on P. vivax remains largely neglected. Methods A pilot survey of expressed sequence tags (ESTs) from the asexual blood stages of P. vivax was performed. To do so, 1,184 clones from a cDNA library constructed with parasites obtained from 10 different human patients in the Brazilian Amazon were sequenced. Sequences were automatedly processed to remove contaminants and low quality reads. A total of 806 sequences with an average length of 586 bp met such criteria and their clustering revealed 666 distinct events. The consensus sequence of each cluster and the unique sequences of the singlets were used in similarity searches against different databases that included P. vivax, Plasmodium falciparum, Plasmodium yoelii, Plasmodium knowlesi, Apicomplexa and the GenBank non-redundant database. An E-value of <10-30 was used to define a significant database match. ESTs were manually assigned a gene ontology (GO) terminology Results A total of 769 ESTs could be assigned a putative identity based upon sequence similarity to known proteins in GenBank. Moreover, 292 ESTs were annotated and a GO terminology was assigned to 164 of them. Conclusion These are the first ESTs reported for P. vivax and, as such, they represent a valuable resource to assist in the annotation of the P. vivax genome currently being sequenced. Moreover, since the GC-content of the P. vivax genome is strikingly different from that of P. falciparum, these ESTs will help in the validation of gene predictions for P. vivax and to create a gene index of this malaria parasite.

From 1986 to 1994, Patrick Chamoiseau and Raphaël Confiant published a series of fictional and non-fictional writings focusing on language issues. Interest in these themes can certainly in part be explained by the "surconscience linguistique" that Lise Gauvin attributes to Francophone authors: a linguistic over-awareness which, in the case of these two Martiniquais writers, may be attributed to their Creole-French diglossia. Although we might believe that the idea of Gauvin is right, it doesn't seem enough to explain why the linguistic theme plays such a central role in Chamoiseau's and Confiant's works. Deeply influenced by Glissant's theories on Creole popular culture and Antillean literature (Le discours antillais), they conceived a "Créolité" poetics based on a primarly identity-based and geopolitical discourse. Declaring the need to build an authentically Creole literary discourse, one that finally expresses the Martiniquais reality, Chamoiseau and Confiant (as well as Bernabé, third and last author of Éloge de la créolité) found the «foundations of [their] being» in orality and its poetics in the Creole language. This belief was maily translated into their works in two ways: by representing the (diglossic) relationships occurring between their first languages (Creole and French) and by representing the Creole parole (orality) and its function. An analysis of our authors' literary and theoretical writings will enable us to show how two works that develop around the same themes and thesis have in fact produced very divergent results, which were perhaps already perceivable in the main ambiguities of their common manifestos.

Che rapporto intercorre tra un’opera letteraria e una sua interpretazione? Che cosa fa sì che la prima supporti la seconda? Come possiamo discernere un’interpretazione valida da una che non lo è ? Come può una stessa opera avere interpretazioni differenti e a volte incompatibili tra loro? Assumendo come punto di partenza la proposta di Nelson Goodman di qualificare l’opera letteraria come allografica e, quindi, di definire l’identità dell’opera sulla base della sua compitazione, cercare un risposta alle domande proposte implica un riflessione tanto sul linguaggio, quale strumento simbolico, quanto sulle modalità di riferimento proprie delle opere letterarie. In particolare, di fronte al dissolversi del mondo nella molteplicità delle versioni che il linguaggio può offrire di esso, una peculiare concezione della metafora, intesa come proiezione di un regno del linguaggio su un altro regno dello stesso, si qualifica come un buon modello per la comprensione del rapporto che lega opere letterarie e loro interpretazioni. In tal modo l’opera stessa non solo diviene significativa, ma, attraverso tale significazione, riesce anche a farsi produttiva, modificando, ampliando, ristrutturando la versione dal mondo dalla quale l’interprete-lettore prende le mosse. Ciascuna lettura di un’opera letteraria può infatti essere concepita come una via attraverso la quale ciò che nell’opera è detto viene proiettato sulla visione del mondo propria dell’interprete e di quanti possono condividerne il punto di vista. In tal modo le interpretazioni pongono le opere cui si riferiscono nelle condizioni di fornire un apporto significativo tanto alla comprensione quanto alla costituzione della nostra versione del mondo. E se ciò può avvenire in diversi modi, mutando le interpretazioni a seconda di chi le produce e delle circostanze in cui sorgono, l’opera evita la dissoluzione in virtù della compitazione che la identifica.

Our study evaluates the dimensionality and equivalence of social trust across cultural contexts, using new data from Switzerland and the World Values Survey 2005–2008. Whereas some scholars assert that trust should be regarded as a coherent concept, others claim that trust is better conceived of as a multidimensional concept. In contrast to the conventional dichotomy of the forms of social trust, we identify three distinct forms of trust, namely, particularized, generalized, and identity-based trust. Moreover, we dispute the view that respondents understand the wording of survey questions regarding social trust differently between different cultural contexts, which would imply that comparative research on trust is a pointless endeavor. Applying multiple-group confirmatory factor analysis to the various constructs of social trust, we conclude that one may study relationships among the three forms of trust and other theoretical constructs as well as compare latent means across cultural contexts. Our analyses therefore provide an optimistic outlook for future comparative analyses that investigate forms of social trust across cultural contexts.

The study of secession generally stresses the causal influence of cultural identities, political preferences, or ecological factors. Whereas these different views are often considered to be mutually exclusive, this paper proposes a two-stage model in which they are complementary. We posit that cultural identities matter for explaining secessionism, but not because of primordial attachments. Rather, religious and linguistic groups matter because their members are imbued with cultural legacies that lead to distinct political preferences – in this case preferences over welfare statism. Further, ecological constraints such as geography and topography affect social interaction with like-minded individuals. On the basis of both these political preferences and ecological constraints, individuals then make rational choices about the desirability of secession. Instrumental considerations are therefore crucial in explaining the decision to secede, but not in a conventional pocketbook manner. To examine this theory, we analyze the 2013 referendum on the secession of the Jura Bernois region from the Canton of Berne in Switzerland, using municipal level census and referendum data. The results lend support to the theory and suggest one way in which the politics of identity, based on factors like language and religion, can be fused with the politics of interest (preferences for more or less state intervention into the polity and economy) to better understand group behavior.

Para la sociedad del Antiguo Egipto el mito era la forma de legitimación y la explicación de porqué el mundo adquiría determinada forma y orden. El paso de una economía cazadora- recolectora a una propiamente agrícola provoca un cambio de mentalidad en donde la figura del rey aparece como garante del orden dado. En este trabajo analizaremos la construcción de la identidad del rey en el Antiguo Egipto en base a dos interrogantes: los orígenes topográficos del culto a Osiris y cómo a través del mito se produce la identificación de Osiris el rey-padre muerto con su sucesor Horus-rey-hijo-vivo, todo esto vinculado a la formación del Estado

La tesis doctoral “La construcción de la transparencia. Museo de Arte Contemporáneo del Siglo 21 de Kanazawa / SANAA” estudia, desde diferentes perspectivas, esta obra de los arquitectos japoneses Kazuyo Sejima + Ryue Nishizawa / SANAA. El museo, proyectado y construido entre 1999 y 2004, supone un referente arquitectónico de gran relevancia en el cambio de siglo, y está considerado un manifiesto construido en el que resuenan ecos culturales y sociales de su época. La investigación toma como constante el Museo del Siglo 21 de Kanazawa y a través de él se realizan una serie de miradas transversales a modo de narrativas interconectadas. Estas visiones múltiples colaboran, a través de las relaciones que se producen entre ellas, a generar un entendimiento global de esta obra y sus efectos sobre la cultura arquitectónica contemporánea. La tesis se estructura en dos partes: la primera estudia de manera analítica la obra en su contexto cultural, el proceso de proyecto y el edificio construido. La segunda parte propone una triple lectura interpretativa del edificio en relación a temas de especial relevancia para el proyecto y al modelo de espacio que constituye, tomando de nuevo como constante la noción de transparencia. La tesis partirá de la interpretación que hace del museo su directora artística Yuko Hasegawa, cuya colaboración activa durante el proceso de diseño resultó de gran relevancia para el resultado final. Hasegawa define la obra como la materialización de una situación cultural característica del nuevo siglo basada en tres conceptos: La Coexistencia, la Consciencia y la Inteligencia Colectiva. A partir de dichas ideas entenderemos la transparencia no sólo desde el punto de vista de las cualidades físicas y materiales del espacio sino también, desde una perspectiva más amplia: como estrategia utilizada para clarificar la organización funcional del edificio y las relaciones entre sus partes como posición política, catalizadora del espacio público; la producción de consciencia a través de la experiencia del arte y la arquitectura; y como medio de representación y generación de una identidad colectiva basada en la visibilidad mediática. Las conclusiones de esta investigación, extraídas de las confluencias y puntos de intersección de las diferentes miradas transversales proyectadas sobre la obra, determinan una clara voluntad por parte de los arquitectos de construir un espacio donde lo público se entiende como el ensamblaje de diferentes individualidades. De manera similar al proceso de proyecto, la multiplicidad y las relaciones entre elementos autónomos generan un consciencia colectiva del espacio donde, a través de la organización programática, la construcción y el uso de los materiales y la luz, la arquitectura tiene la voluntad de desvanecerse para ofrecer protagonismo a sus usuarios y a las relaciones y encuentros que se producen entre ellos y con el espacio que habitan. ABSTRACT The PhD thesis “The construction of transparency. 21st Century Museum of Contemporary Art in Kanazawa / SANAA” studies, from different perspectives, this work, realized by Japanese architects Kazuyo Sejima + Ryue Nishizawa / SANAA. The museum, designed and built between 1999 and 2004, had a huge relevance as an architectural referent in the swift of the century, being considered a built manifesto that echoes the culture and society of its time. The research takes as a constant the 21st Century Museum in Kanazawa and it is studied throughout a series of transversal readings as interconnected narratives. These multiple approaches and the relations among them, help to generate a global understanding of the building and its effects on contemporary architectural culture. The dissertation is structured in two parts: the first one studies from an analytical perspective the project in its cultural context, the process of design and the built work. The second part proposes a triple interpretative reading of the building in relation to topics that are especially relevant for the project and the spatial model that it constitutes, taking again the notion of transparency as a constant concept. The thesis departs from the interpretation expressed by the artistic director of the museum, Yuko Hasegawa, whose active collaboration during the design process had special relevance for the final result. She defines the work as the materialization of the cultural context of the new century based in three concepts: Co-existence, Consciousness and Collective Intelligence. From these concepts we will understand transparency, not only from the point of view of the physical and material qualities of the space, but also from a broader perspective: as an strategy used to clarify the functional organization of the building and the relation of its parts as political stand that catalyzes the public space; the production of consciousness based on the experience of art and architecture; and as a method of representation and construction of a collective identity based in the media visibility. The conclusions of this research -extracted from the confluences and intersections of the different transversal readings projected on the work- determine a clear intention by the architects to build a space where the public is understood as an assembly of different individualities. In a similar way as it happens in the design process, the multiplicity of relations between autonomous elements generate a collective consciousness of the space. Throughout the programmatic organization, the construction and the use of light and materials, the architecture has the will of disappearance to yield protagonist the users and the relations and encounters that happen among them and the space they inhabit.

For decades, the international community has recognized that youth are some of the most vulnerable to mental and emotional distress within the intractable and cyclical nature of identity-based violent conflict. Exposure to traumatic stressors within these intergroup conflicts poses unique risks not only to the neurological and social development of youth, but also to the capacities of youth to fully participate in peacebuilding interventions. The peacebuilding field has yet to strongly consider how traumatic stress affects dynamics within programs for youth and how these programs may need to modify expectations of youth’s cognitive, social, and emotional functioning to account for the traumatic dimensions of political and social violence. Through a qualitative analysis of practitioner reflections gathered from an online survey distributed worldwide, this study explores how practitioners conceptualize and approach issues of traumatic stress in peacebuilding programs focused on youth in conflict-affected contexts. The objective is to identify the working assumptions undergirding practitioner conceptualizations and approaches to traumatic stress and gaps in trauma interventions in peacebuilding programs for youth. The implications of these findings will support efforts to enhance trauma-sensitive peacebuilding practice by revisiting and reconsidering preexisting norms.

La Criptografía Basada en la Identidad hace uso de curvas elípticas que satisfacen ciertas condiciones (pairingfriendly curves), en particular, el grado de inmersión de dichas curvas debe ser pequeño. En este trabajo se obtienen familias explicitas de curvas elípticas idóneas para este escenario. Dicha criptografía está basada en el cálculo de emparejamientos sobre curvas, cálculo factible gracias al algoritmo de Miller. Proponemos una versión más eficiente que la clásica de este algoritmo usando la representación de un número en forma no adyacente (NAF).
