This research paper seeks to bring into view the present-day situation of Native-American narrative in English. It is divided into four chapters. The first deals with the emergence of what we might call a Native-American narrative style and its evolution from 1900 up until its particularly forceful expression in 1968 with the appearance of N. Scott Momaday’s novel House Made of Dawn. To trace this evolution, we follow the chronology set forth by Paula Gunn Allen in her anthology Voice of the Turtle: American Indian Literature 1900-1970. In the second chapter we hear various voices from contemporary Native-American literary production as we follow Simon J. Ortiz’s anthology Speaking for the Generations: Native Writers on Writing. Noteworthy among these are Leslie Marmon Silko and Gloria Bird, alongside new voices such as those of Esther G. Belin and Daniel David Moses, and closing with Guatemalan-Mayan Victor D. Montejo, exiled in the United States. These writers’ contributions gravitate around two fundamental notions: the interdependence between human beings and the surrounding landscape, and the struggle for survival, which of necessity involves the deconstruction of the (post-)colonial subject. The third chapter deals with an anthology of short stories and poems by present-day Native-American women writers, edited by Joy Harjo and Gloria Bird and entitled Reinventing the Enemy’s Language: Contemporary Native Women’s Writings of North America. It too exemplifies personal and cultural reaffirmation on a landscape rich in ancestral elements, but also where one’s own voice takes shape in the language which, historically, is that of the enemy. In the final chapter we see how translation studies provide a critical perspective and fruitful reflection on the literary production of Native-American translative cultures, where a wide range of writers struggle to bring about the affirmative deconstruction of the colonialised subject. Thus there comes a turnaround in the function of the “enemy’s language,” giving rise also to the question of cultural incommensurability.

Aphids are important agricultural pests and also biological models for studies of insect-plant interactions, symbiosis, virus vectoring, and the developmental causes of extreme phenotypic plasticity. Here we present the 464 Mb draft genome assembly of the pea aphid Acyrthosiphon pisum. This first published whole genome sequence of a basal hemimetabolous insect provides an outgroup to the multiple published genomes of holometabolous insects. Pea aphids are host-plant specialists, they can reproduce both sexually and asexually, and they have coevolved with an obligate bacterial symbiont. Here we highlight findings from whole genome analysis that may be related to these unusual biological features. These findings include discovery of extensive gene duplication in more than 2000 gene families as well as loss of evolutionarily conserved genes. Gene family expansions relative to other published genomes include genes involved in chromatin modification, miRNA synthesis, and sugar transport. Gene losses include genes central to the IMD immune pathway, selenoprotein utilization, purine salvage, and the entire urea cycle. The pea aphid genome reveals that only a limited number of genes have been acquired from bacteria; thus the reduced gene count of Buchnera does not reflect gene transfer to the host genome. The inventory of metabolic genes in the pea aphid genome suggests that there is extensive metabolite exchange between the aphid and Buchnera, including sharing of amino acid biosynthesis between the aphid and Buchnera. The pea aphid genome provides a foundation for post-genomic studies of fundamental biological questions and applied agricultural problems.

This article is a reflection on a master thesis. The article tries to unravel some of the interdisciplinary keys present in the work and necessary for the development of research on Public Space and Public Art. At the same time argues in favor of"post colonial" reading over the-produced space by the colonial powers, both in terms of its structural dimension and in the dimension of 'decorum'.

An abundant scientific literature about climate change economics points out that the future participation of developing countries in international environmental policies will depend on their amount of pay offs inside and outside specific agreements. These studies are aimed at analyzing coalitions stability typically through a game theoretical approach. Though these contributions represent a corner stone in the research field investigating future plausible international coalitions and the reasons behind the difficulties incurred over time to implement emissions stabilizing actions, they cannot disentangle satisfactorily the role that equality play in inducing poor regions to tackle global warming. If we focus on the Stern Review findings stressing that climate change will generate heavy damages and policy actions will be costly in a finite time horizon, we understand why there is a great incentive to free ride in order to exploit benefits from emissions reduction efforts of others. The reluctance of poor countries in joining international agreements is mainly supported by historical responsibility of rich regions in generating atmospheric carbon concentration, whereas rich countries claim that emissions stabilizing policies will be effective only when developing countries will join them.Scholars recently outline that a perceived fairness in the distribution of emissions would facilitate a wide spread participation in international agreements. In this paper we overview the literature about distributional aspects of emissions by focusing on those contributions investigating past trends of emissions distribution through empirical data and future trajectories through simulations obtained by integrated assessment models. We will explain methodologies used to elaborate data and the link between real data and those coming from simulations. Results from this strand of research will be interpreted in order to discuss future negotiations for post Kyoto agreements that will be the focus of the next. Conference of the Parties in Copenhagen at the end of 2009. A particular attention will be devoted to the role that technological change will play in affecting the distribution of emissions over time and to how spillovers and experience diffusion could influence equality issues and future outcomes of policy negotiations.

El objetivo de este estudio es contribuir al entendimiento, desde un punto de vista histórico, del papel que juega el cine en los procesos de popularización de la ciencia, la medicina y la tecnología. El punto de partida es la consideración de la medicina y del cine como conjuntos complejos y multidimensionales de “prácticas y discursos” de carácter científico-tecnológico y, por tanto, como formas particulares de acción e interacción cotidiana entre personas, colectivos e instituciones que juegan un papel básico en los procesos de construcción y funcionamiento de las sociedades contemporáneas. Así, mediante el análisis de la representación y articulación de las prácticas y los discursos médico-sanitarios en el cine documental colonial español del primer franquismo, es decir, en el caso particular de la construcción, legitimación y consolidación de un régimen totalitario, se aportan algunas claves explicativas sobre las múltiples relaciones entre diferentes colectivos (expertos y no-expertos) en cuanto a la naturaleza y el nivel de intervención en los procesos de generación y gestión de conocimiento científico-tecnológico. Como resultado, el cine se revela como un espacio no sólo de evasión y entretenimiento, sino también de ciencia y educación, donde la capacidad de definir y solucionar problemas cotidianos de la población, y por tanto, su impacto en la construcción de la arquitectura social, ideológica, económica, política y cultural de las sociedades contemporáneas, se fundamenta en la combinación de sus aspectos como espectáculo narrativo y científico-tecnológico.

The dominant hypothesis in the literature that studies conflict is that poverty is the main cause of civil wars. We instead analyze the effect of institutions on civil war, controlling for income per capita. In our set up, institutions are endogenous and colonial origins affect civil wars through their legacy on institutions. Our results indicate that institutions, proxied by the protection of property rights, rule of law and the efficiency of the legal system, are a fundamental cause of civil war. In particular, an improvement in institutions from the median value in the sample to the 75th percentile is associated with a 38 percentage points reduction in the incidence of civil wars. Moreover, once institutions are included as explaining civil wars, income does not have any effect on civil war, either directly or indirectly.

Huntingtin regulates post-Golgi trafficking of secreted proteins. Here, we studied the mechanism by which mutant huntingtin impairs this process. Colocalization studies and Western blot analysis of isolated Golgi membranes showed a reduction of huntingtin in the Golgi apparatus of cells expressing mutant huntingtin. These findings correlated with a decrease in the levels of optineurin and Rab8 in the Golgi apparatus that can be reverted by overexpression of full-length wild-type huntingtin. In addition, immunoprecipitation studies showed reduced interaction between mutant huntingtin and optineurin/Rab8. Cells expressing mutant huntingtin produced both an accumulation of clathrin adaptor complex 1 at the Golgi and an increase of clathrin-coated vesicles in the vicinity of Golgi cisternae as revealed by electron microscopy. Furthermore, inverse fluorescence recovery after photobleaching analysis for lysosomal-associated membrane protein-1 and mannose-6-phosphate receptor showed that the optineurin/Rab8-dependent post-Golgi trafficking to lysosomes was impaired in cells expressing mutant huntingtin or reducing huntingtin levels by small interfering RNA. Accordingly, these cells showed a lower content of cathepsin D in lysosomes, which led to an overall reduction of lysosomal activity. Together, our results indicate that mutant huntingtin perturbs post-Golgi trafficking to lysosomal compartments by delocalizing the optineurin/Rab8 complex, which, in turn, affects the lysosomal function.

The approaches of comparative studies and profile measurements, often used in order to detect post-depositional alterations of ceramics, have been applied simultaneously to two sets of Roman pottery, both of which include altered individuals. As analytical techniques, Neutron Activation Analysis and X-Ray Diffraction have been used. Both approaches lead to substantially different results. This shows that they detect different levels of alteration and should complement each other rather than being used exclusively. For the special process of a glassy phase decomposition followed by a crystallization of the Na-zeolite analcime, the results suggest that it changes high-fired calcareous pottery rapidly, and so fundamentally that the results of various archaeometric techniques can be severely disturbed.

The appearance and popularization of the internet has created new forms of writing, which compel us to think anew about identity and subjectivity. Webjournals or blogs are specially interesting because they are a massive phenomenon that use autobiographical writing in a peculiar way. These forms of writing stress a particular paradox of the genre: the coexistence between a purpose of private, confessional and spontaneous writing and a public image, carefully built, as a result of its writing. The technology is new, but, in fact, the paradox is old. This paper tries to explore this old paradox, our eternal condition of cyborgs, our use of technologies in order to construct a public, unique and recognizably identity. In oder to do so, I will try to show the virtual condition of any written individual ¿this issue has already been dealt with by autobiographical studies¿, focusing on blogs, and especially on concrete example (Lord Whimsy¿s Journal). I will pay attention to gender as a technology that constructs identity and, at the same time, is deconstructed by the autobiographical narratives analyzed. In short, I attempt to show that virtual and autobiographical discourse do not bring forth a new kind of subject but the permanence of an old phenomenon "clearly developed by dandyism, for instance¿: the use of tehnologies to re-invent, re-formulate and re-construct us as multiple, hybrid and mixed subjects."

Brain-derived neurotrophic factor (BDNF) polymorphism is associated with the pathophysiology of several neurodegenerative disorders, including Huntington"s disease. In view ofthese data andthe involvement of huntingtin in intracellular trafficking, we examined the intracellular transport and release of Val66Val BDNF (Val-BDNF) and Val66Met BDNF (Met-BDNF) in transfected striatal knock-in cells expressing wild-type or mutant full-length huntingtin. Colocalization studies with specific markers for endoplasmic reticulum showed no differences between the Val-BDNF and Met-BDNF and were not modified by mutant huntingtin. However, post-Golgi trafficking was altered by mutant huntingtin dependent on the BDNF form. Thus, fluorescence recovery after photobleaching (FRAP) and inverse FRAP analysis showed retention of Met-BDNF inthe Golgi apparatus with respectto Val-BDNF in wild-type cells. Strikingly, mutant huntingtin diminished post-Golgi trafficking of Val-BDNF, whereas Met-BDNF was not modified. Accordingly, a reduction in the number of transport vesicles was only observed in mutant huntingtin cells transfected with Val-BDNF but not Met-BDNF. Moreover, mutant huntingtin severely affectedthe KCl-evoked release of Val-BDNF, although it had little effect on Met-BDNF regulated release. The constitutive release of Val-BDNF or Met-BDNF in mutant cells was only slightly reduced. Interestingly, mutant huntingtin only perturbed post-Golgi trafficking of proteins that follow the regulated secretory pathway (epidermal growth factor receptor or atrial natriuretic factor), whereas it did not change those that follow the constitutive pathway (p75 NTR ). We conclude that mutant huntingtin differently affects intracellular transport and release of Val-BDNF and Met-BDNF. In addition, our findings reveal a new role for huntingtin in the regulation of the post-Golgi trafficking of the regulated secretory pathway.

Ralstonia solanacearum is a soil-borne bacterium causing the widespread disease known as bacterial wilt. Ralstonia solanacearum is also the causal agent of Moko disease of banana and brown rot of potato. Since the last R. solanacearum pathogen profile was published 10 years ago, studies concerning this plant pathogen have taken a genomic and post-genomic direction. This was pioneered by the first sequenced and annotated genome for a major plant bacterial pathogen and followed by many more genomes in subsequent years. All molecular features studied now have a genomic flavour. In the future, this will help in connecting the classical field of pathology and diversity studies with the gene content of specific strains. In this review, we summarize the recent research on this bacterial pathogen, including strain classification, host range, pathogenicity determinants, regulation of virulence genes, type III effector repertoire, effector-triggered immunity, plant signalling in response to R. solanacearum, as well as a review of different new pathosystems.

Introducción: A pesar de ser considerados eventos infrecuentes en comparación a otros estados patológicos relacionados con la alimentación, en los últimos años y en diferentes países, se constata un incremento de las tasas de incidencia y prevalencia de los Tras - tornos del Comportamiento Alimentario; la mayoría de estudios que analizan los factores que pueden influir en su aparición, suelen implicar a jóvenes y adolescentes de poblaciones pre-mórbidas o mórbidas, siendo menos frecuentes los realizados sobre población sana y estándar. Objetivos: Evaluar el nivel de conocimientos acerca de los Trastornos del Comportamiento Alimentario y comprobar la eficacia de una intervención educativa, en jóvenes de una población presumiblemente sana. Métodos: Estudio de intervención con evaluación pre y post intervención, a través de un cuestionario previamente validado de 10 preguntas cerradas y abiertas, en estudiantes de Fisioterapia, Educación Infantil y Hostelería. Resultados: Respondieron el cuestionario inicial 154 estu diantes, 85 universitarios y 39 de ciclo formativo en Hostelería, mayoritariamente mujeres (68%) y con una edad media de 20,8 años. Los estudiantes demostraron un nivel medio de conocimientos inicial, mayor en las mujeres y en los estudiantes universitarios que en los de formación profesional. Los factores de riesgo y las manifestaciones clínicas fueron los aspectos menos conocidos por los estudiantes. La intervención educativa realizada en los 35 estudiantes de Hostelería que participaron en el taller y respondieron el cuestionario post-intervención, consiguió elevar el nivel de conocimientos hasta una calificación media superior a la inicial y a la de los grupos en que no se realizó la intervención. Discusión y conclusiones: A pesar de que la intervención realizada resultó eficaz para mejorar el nivel de conocimientos en muchos de los participantes, los resultados del cuestionario post-intervención revelan la necesidad de educar a los jóvenes en los rasgos que definen y caracterizan un Trastorno del Compor tamiento Alimen - tario, adaptando el abordaje de los mismos a su realidad social. La inclusión de temas relacionados con la nutrición y la salud en los programas curriculares de los estudios post-obligatorios mejoraría el nivel de conocimientos entre los futuros profesionales de los ámbitos de la salud, la educación y la hostelería/restauración.
