Representació gràfica i ècfrasi en l’obra de Ramon Llull
2016
El present treball estudia la relació que s’estableix entre text i representacions gràfiques en les obres de Ramon Llull, fent una atenció especial al recurs retòric anomenat ècfrasi, això és, la descripció verbal d’un objecte visual. S’analitzen casos de descripció de figures lul·lianes, sobretot esquemes arboris, en presència de la seva representació (ècfrasi referencial) o en absència de la mateixa (ècfrasi nocional). Es conclou que la dimensió material de les figures i l’assimilació mental del seu funcionament són elements cabdals del procés d’elevació cognitiva que proposa Llull This article discusses the relation established between texts and graphic representations in works of Ramon …
The effect of teacher feedback on EFL learners' functional production in classroom discourse.
2005
The present study is based on the analysis of classroom interactions between children and with their teacher both in first and second language contexts. The subjects of our study are two five-year-old classes in an English bilingual school in Madrid, with two different teachers, and one five-year-old monolingual class. The source of our analysis is Halliday’s classification of the communicative functions that children can convey in their mother tongue at the pre-school level (Halliday, 1975). Our premise is that the functional variety of children’s production and their use of language for their own communicative purposes is highly related to both frequency and type of teacher feedback. This…

Perfil genético, epigenético e inmunohistoquímico en los cánceres de mama esporádicos y hereditarios
2016
El cáncer de mama (CM) es una de las principales causas de muerte por cáncer en la mujer en todo el mundo. En la actualidad el CM se entiende como una enfermedad heterogénea que abarca una serie de entidades definidas por sus diferentes características biológicas y comportamientos clínicos. Todo ello ha llevado a la búsqueda de biomarcadores que, a nivel individual o en combinación con otros marcadores (perfiles), ofrezcan a una mayor precisión diagnóstica, en el comportamiento evolutivo y en la predicción de la respuesta terapéutica. El presente estudio considera como mecanismo etiopatogénico de referencia del CM las mutaciones en los genes supresores tumorales BRCA1 y BRCA2, característic…
Estudio del perfil de microRNAs circulantes en pacientes con déficit de alfa-1 antitripsina. Implicaciones diagnósticas, pronósticas y terapéuticas
2017
El déficit de alfa-1 antitripsina (DAAT) es una condición genética rara y hereditaria que conduce a la disminución de los niveles circulantes de alfa-1 antitripsina, aumentando significativamente el riesgo de padecer enfermedad pulmonar y hepática grave, en niños y adultos. Esta condición tiene una gran variabilidad, tanto genética como clínica, lo que dificulta su pronóstico. Los microRNAs son unas pequeñas moléculas alrededor de 22nt cuya función es la regulación de la expresión génica. Además, estas moléculas tienen gran potencial como biomarcadores por su localización en fluidos corporales, como la sangre, provenientes de órganos altamente vascularizados, incluyendo pulmones e hígado; s…
The Cth2 ARE-binding protein recruits the Dhh1 helicase to promote the decay of succinate dehydrogenase SDH4 mRNA in response to iron deficiency
2008
Iron is an essential nutrient that participates as a redox co-factor in a broad range of cellular processes. In response to iron deficiency, the budding yeast Saccharomyces cerevisiae induces the expression of the Cth1 and Cth2 mRNA-binding proteins to promote a genome-wide remodeling of cellular metabolism that contributes to the optimal utilization of iron. Cth1 and Cth2 proteins bind to specific AU-rich elements within the 3'-untranslated region of many mRNAs encoding proteins involved in iron-dependent pathways, thereby promoting their degradation. Here, we show that the DEAD box Dhh1 helicase plays a crucial role in the mechanism of Cth2-mediated mRNA turnover. Yeast two-hybrid experim…
Quantitative importance of staminodes for female reproductive success inParnassia palustrisunder contrasting environmental conditions
2003
The five sterile stamens, or staminodes, in Parnassia palustris act both as false and as true nectaries. They attract pollinators with their conspicuous, but non-rewarding tips, and also produce nectar at the base. We removed staminodes experimentally and compared pollinator visitation rate and duration and seed set in flowers with and without staminodes in two different populations. We also examined the relative importance of the staminode size to other plant traits. Finally, we bagged, emasculated, and supplementary cross-pollinated flowers to determine the pollination strategy and whether reproduction was limited by pollen availability. Flowers in both populations were highly dependent o…
Reassessment of international executive institutions : the case of the European Commission, the OECD secretariat and the WTO secretariat
2006
Masteroppgave i økonomi og administrasjon 2006 - Høgskolen i Agder, Kristiansand This master thesis focuses on the dynamics within the International Executives (IEs) of International Governmental Organizations: the European Union, the Organisation for Economic Cooperation and Development (OECD) and the World Trade Organization (WTO). This master thesis has its intention to examine the ways these IEs challenge the principle of sovereignty, why they do go beoynd the existing heritage of Westphalia. Dependent and independent variables will be defined in order to examine this matter. The dependent variable is decision-making dynamics that are evoked by civil servants of these IEs. There are fou…
The emergence of supranationalism and intergovernmentalism in European defence cooperation : the role of PESCO and its Secretariat
2020
Master's thesis in Political science and management (ME502) For a long time,theEuropean Union’s(EU) member states have meticulously ring-fenced defence cooperation vis-à-vis the potential intrusion of supranationalism. Thus, defence cooperation has been conceived as perhaps the most central part of core state powers in Europe. Has this changed since member states have agreed to establish the so-called Permanent Structured Cooperation (PESCO) in 2017? Cleary, PESCO has developed bothas a more structuredand legally ‘binding’cooperation in defence mattersamongst participating member states, such as defence procurement, training and capability development.Yet, the jury is out for as to whether …
The Making of EU Foreign Policy Strategy : The case of Central Asia
2019
Master's thesis Public Policy and Management ME502 - University of Agder 2019 This thesis examinesthe EU foreign policy agenda-setting with regards to the drafting of the Union’snew Central Asia strategy. The EU Strategy for Central Asia was eventually released May 2019.The thesis adopts the analytical framework of Europeanization and seeks to explainthe coordination between the EU institutions on the one hand and howmember states influence EU foreign policy strategy-makingon the other.Analytically,the Europeanization framework subscribes to exploringthe EU’s impact on member states (‘down-loading’)andthe capacity of member states to shape the direction of the EU(‘up-loading’). The down-loa…
