Abstract:
El famoso drama quechua Ollantay. cuya primera versión escrita se realizó sin duda en la segunda mitad del siglo XVIII, ha suscitado una polémica larga, a menudo estéril y repetitiva, entre los defensores de su supuesto origen incaico y los que insisten, por el contrario, en sus rasgos coloniales e hispánicos.

Abstract:
Betanhe (betana + / h + exchanger) est la seule isoforme d'echangeur na + / h + activee par les agonistes des recepteurs beta adrenergiques. La region c-terminale de betanhe possede les elements necessaires a l'activation ampc-dependante de l'echangeur. En effet, la proteine chimere formee du domaine transmembranaire de l'isoforme nhe-1 (fortement homologue a betanhe) et du domaine cytoplasmique de betanhe, est activee par l'ampc, contrairement a nhe-1. Sur le domaine cytoplasmique de betanhe, sont localises deux sites concensus de phosphorylation reconnus specifiquement par la proteine kinase ampc-dependante (pka), qui sont impliques dans l'activation de l'echangeur par l'ampc. En effet, les experiences de phosphorylation in vitro montrent que betanhe est substrat de la pka et la mutation des deux sites pka reduit de 72% la stimulation de betanhe par l'ampc. Cependant ces elements ne sont pas a eux seuls suffisants car l'echangeur hybride n3beta, forme du domaine transmembranaire de l'isoforme nhe-3 (peu homologue a betanhe) et de la region cytoplasmique de betanhe, est insensible a l'ampc. Des sequences du domaine transmembranaire, conservees entre betanhe et nhe-1, mais absente sur l'isoforme nhe-3, sont indispensables a l'activation ampc-dependante de betanhe. Par ailleurs, nous avons montre que deux domaines proteiques (localises dans la region transmembranaire) doivent etre issus de la meme isoforme (betanhe ou nhe-3) pour permettre l'expression des echangeurs chimeres sur la membrane plasmique, suggerant l'existence d'une complementarite structurale entre ces 2 domaines, indispensable a l'adressage des echangeurs.

Abstract:
Den svenska hagmarken och dess biologiska mångfald är hotade, men det finns en vilja från samhället att bevara det biologiskt och pedagogiskt viktiga utrymme som hagmarkerna utgör. Det finns dessutom behov av mer ekologiska och ekonomiska metoder att förvalta stadsnära natur. Betande djur i stadsnära grönområden används i flera kommuner som en del av lösningen på dessa problem, och detta examensarbete undersöker hur betande djur påverkar ett områdes biologi, och hur betande djur fungerar som en del av skötseln av stadsnära natur. Den metod som använts är litteraturstudier. Som ett komplement har fyra intervjuer gjorts med ansvariga personer på förvaltningar som arbetar med betande djur. Resultatet visar att en grönyta påverkas på många sätt av bete: Floran och faunan förändras och blir artrikare, beroende på störningar i form av bland annat det tramp som marken utsätts för vid bete. Förvaltningarna använder betande djur framför allt för att bevara den biologiska mångfalden och det öppna kulturlandskapet, men även som ett pedagogiskt, miljömässigt försvarbart och attraktivt inslag i de stadsnära grönområdena. De tillfrågade förvaltningarna upplever att skötsel av stadsnära natur med hjälp av betande djur i huvudsak har fungerat bra, och att det bidragit till att de betade områdena har erhållit ökade biologiska och kulturella värden. Det behövs dock ytterligare inventeringar för att säkert kunna visa hur en restaurerad betesmarks flora och fauna förändras vid ett återinfört bete. Betande djur bedöms kunna användas i större utsträckning som en realistisk och ekologisk del av förvaltning av stadsnära natur, förutsatt att djurens säkerhet kan upprätthållas.

Abstract:
Le « cas » Juan de Betanzos (1519-1576) est en apparence extrêmement simple et peut se résumer en quelques mots : en 1551, à Cuzco, un Espagnol, marié à une princesse indigène, écrit une histoire des Incas à la demande du vice-roi de l’époque, don Antonio de Mendoza. Cette simplicité explique sans doute, pourquoi ce « cas » n’a pas suscité davantage d’intérêt. Si la Suma y narración de los Incas, depuis la découverte d’une version complète en 1987, est unanimement considérée comme une source fondamentale pour la connaissance du Tahuantinsuyo et un passage obligé pour tout spécialiste du Monde andin, son contexte d’élaboration, ses sources et même son auteur n’ont reçu qu’une attention fort limitée. Ce dernier a été relégué à l’arrière-plan au sein de son propre ouvrage et cantonné à un second rôle au sein de la société de son époque. Abordé comme un « passeur culturel » et un « expert » de la langue quechua et du monde inca, Betanzos acquiert un tout autre relief : il n’apparaît plus comme un personnage secondaire, mais comme un acteur du processus de transition entre monde préhispanique et monde hispanique et de la construction de la société coloniale péruvienne<br>The “case” of Juan de Betanzos (1519-1576), apparently simple, can be summed up in a few words: in 1551, in Cuzco, a Spaniard, married to an indigenous princess, writes a history of the Incas, commissioned by the viceroy at the time, don Antonio de Mendoza. This simplicity undoubtedly explains why this "case" did not raise more interest. Although the Suma y narración de los Incas, since the discovery of a complete version in 1987, has been considered unanimously as a fundamental source for understanding the Tahuantinsuyo, as well as required reading for any specialist of the Andean world, the context of its production, its sources, and even its author have only received very limited attention. The author has been pushed to the background of his own work and confined to a secondary role in his own society. Approached, however, as a “passeur culturel” and an "expert" of the Quechua language and Inca world, Betanzos acquires an altogether different depth: he no longer appears as a secondary character, but as an agent in the process of transition between pre-Hispanic and Hispanic worlds and in the construction of colonial Peruvian society

Abstract:
La politique mise en oeuvre par le président colombien Belisario Bétancourt (1982-1986) en direction de l'Amérique centrale illustre la portée et les limites de l'autonomie dont dispose une puissance régionale moyenne-statut atteint par la Colombie au cours de cette période- dans une politique extérieure donnée lorsque cette politique entre en conflit avec ce que l'administration américaine considère comme son "intérêt national". En rupture avec un certain pragmatisme de la politique extérieure colombienne, le gouvernement de Bétancourt essaie de développer une orientation internationale relativement autonome vis-à-vis des Etats-Unis. Cette politique cherche à éviter la régionalisation et l'internationalisation du conflit armé interne. Dans le développement de ses objectifs, Bétancourt arrive à suppléer la carence relative de ses ressources matérielles au moyen de deux autres ressources de pouvoir. D'abord, par l'association avec quelques pays de la région, il favorise la négociation entre tous les acteurs de la crise centre-américaine. En deuxième lieu, à travers une intense activité diplomatique, il cherche l'appui international à ses gestions. Néanmoins, ses efforts se butent à des multiples obstacles. Mais, les difficultés purement externes sont relativement moins importantes que l'opposition interne des élites -militaires, économiques et politiques- et que les tensions apparues parmi les alliés régionaux. Le gouvernement de Bétancourt se voit obligé de modérer et même de rectifier les efforts déployés en vue d'atteindre une plus grande autonomie. Cependant, les efforts réalisés produisent des résultats, tant directs qu'indirects, nationaux et régionaux fort appréciables.

Abstract:
There are a number of species of geese in Sweden that can be found in large flocks during spring migration, but are also relatively numerous during breeding. The accumulation of geese can cause damage to growing crops, something that costs farmers and the state a large amount annually. In this study, nesting geese were counted in fields in the vicinity of Lake Tåkern, Southern Sweden, during six days in the spring in the year 2015. Their location on the fields was noted to investigate any preferences regarding distances to the lake, buildings, trees and roads. The conclusion is that proximity to water was the factor that had the greatest importance in field selection, but it also showed that they avoid trees but not settlements and roads.

Para entender la religión y las costumbres de los incas, así como la cosmovisión de los pueblos del mundo andino, las crónicas constituyen una fuente fundamental. El culto al dios Viracocha y el culto solar resultan temas importantes y complejos, diferentes cronistas lo describen con distintos énfasis debido a una serie de factores. La presente investigación se enfoca en analizar el culto a estos dioses en la formación del Tahuantisuyu, así como sus estrechos vínculos con los gobernantes incas, a partir del análisis de tres cronistas importantes de la historia de los incas, Juan de Betanzos, Cieza de León y Cabello de Balboa. En primer lugar, se describe el contexto en que fueron escritas las crónicas, el cual influyó en su contenido y en la apreciación que tuvieron sus autores de los incas. Posteriormente, se presenta las descripciones del culto al dios Viracocha y el Sol de los tres autores. Y luego se hará una comparación de las diferencias y similitudes en las descripciones de dichos temas y analizar los distinto énfasis que ponen los tres cronistas y los intereses y restricciones que están detrás de los autores bajo su época.<br>To understand the religion and customs of the Incas, as well as the worldview of the peoples of the Andean world, the chronicles constitute a fundamental source.

Abstract:
This dissertation studies the ethic-esthetic project of the Puerto Rican patriot, Dr. Ramon Emeterio Betances Alacan, during half a century of revolutionary struggle. For this study, we will use various texts on Betances that have been preserved to present time. Among them, Betances by Luis Bonafoux is of great importance, in addition to the texts published by Carlos M. Rama, and the written by Feliz Ojeda Reyes. Furthermore, we will rely on the biography, El Antillano by Ada Suarez Diaz, a text of principal importance for this study. However, La virgen de Borinquen y epistolario intimo, the book that contains Betances' poetry, and some of his revolutionary speeches and proclamations, deserves particular attention since they are fundamental to emphasize the symbiosis between the great loves of the patriarch: the fatherland, liberty and a woman. The first chapter is dedicated to explaining the birth and formation of Betances as a patriarch. We will look into the influences Betances received from the bosom of his home. In addition, we will see the importance that Betances' home upbringing had in his political growth and maturity in the revolutionary Paris of 1848, as well as in the rise of his campaign for the abolition of slavery after his return to Puerto Rico in 1856. This part of our study will aim to link his family experience to his revolutionary activities in Paris, in an attempt to reveal the birth of Betances the patriarch. The second chapter will be dedicated to the study of Betances' epistolary texts. Maria del Carmen Henri Betances, the only woman loved by the patriarch, is the cornerstone upon which these texts will be sustained. Maria del Carmen Henri is the muse that illuminated Betances' existence, and whose sudden death unleashed his most poetic and heart-rending writings. This contributed to the link between his esthetic and political concepts, achieving with this a "betanciana" poetry of the fatherland. In the third chapter we will study the narrative, La Virgen de Borinquen, where we will see the symbols of the beloved woman and the fatherland as the center that moves the spirit of this writer. In the fourth chapter we will analyze some of Betances' poetry, as well as a few of his revolutionary proclamations and speeches, in which he uses biblical references to advocate the independence of Puerto Rico. The final chapter will offer the conclusions of this study.

Abstract:
In vertebrates, Sox10 is a transcription factor essential for the formation of neural crest cells and their derivatives as well as placode-derived inner ear structures. At gastrula stages, both presumptive neural crest and placode cells reside at the neural plate border, between the non-neural ectoderm and the neural plate. Despite their common site of origin, these two cell populations have different characteristics. Neural crest cells are a multipotent, stem cell-like population that arises at all axial levels, migrates extensively in the embryo and forms a wide array of derivatives ranging from neurons to melanocytes and cartilage. On the other hand, placode cells are restricted to the cranial region, have limited migratory capacity and contribute only to sensory structures such as the eye, ear, olfactory epithelium and distal portions of the cranial sensory ganglia. Interestingly, I have identified cis-regulatory modules responsible for the regulation of Sox10 in these two different embryonic regions and at different times. Among these modules, I found a downstream novel cis-regulatory region, Sox10E2,that mediates initial Sox10 expression in cranial neural crest cells and otic placode cells. Through a combination of computational analysis, experimental perturbation of putative upstream transcription factors and their binding sites within the Sox10E2 regulatory module, plus chromatin immunoprecipitation, I revealed a set of direct inputs into Sox10E2 regulatory region. The results show that cMyb, Sox9 and Ets1 are responsible for the initial Sox10 expression in delaminating cranial neural crest cells, whereas cMyb, Sox8 and Pea3 regulate Sox10 expression in the otic placode. Analyzing Sox10 regulation through the enhancer Sox10E2 has helped unravel gene regulatory inputs contributing to both neural crest formation and otic placode development. The finding that paralogous factors activate the same regulatory module in these two populations suggests the intriguing possibility of an ancient cooption of regulatory function and/or a common ancestral crest-placode origin.
