Luis Monfort, traductor de literatura religiosa y novela gótica
No full textLuis Monfort was a Valencian clergyman who pursued a little known translating career that oscillated between the religious book and the gothic novel. The aim of this paper is to survey such a career and recover it from oblivion, paying also special attention to its connections to the strong pedagogical objectives present in the author's work.
Monfort did not use translation as a literary tool to become a writer himself, but rather employed it to defend the conservative status quo of his time, as seen in the prologues he wrote to doctrinal texts like Oficio de la Semana Santa and Evidencia de la religión cristiana contra la filosofía de la incredulidad or gothic novels like La familia de Vieland and Carvino. Despite his efforts, however, in the end Monfort was not remembered for his doctrinal teachings but rather for his gothic leanings.Este trabajo se ha realizado en el marco del proyecto de investigación MINECO FFI2011-28728
Essays in monetary economics
No full textThis thesis studies the optimal conduct of monetary policy in the presence of nominal
and informational frictions. The first chapter studies the optimal policy in a small open
economy model with external asset holdings. I show that optimal policy implies moderate
inflation volatility with counter-cyclical domestic inflation relative to foreign inflation.
The second chapter studies the determinants of financial dollarization and the optimal policy
in emerging economies. I show that inflation targeting does not reduce dollarization
and is not the optimal policy. Instead, the central bank aims to provide insurance against
domestic shocks through its control over domestic inflation. In fact, absent additional frictions,
optimal policy achieves efficient risk sharing among households, while at the same
time completely eliminating dollarization. Finally, the third chapter studies the optimal
monetary policy in a New-Keynesian model with incomplete information. In this setting,
disclosure of public information about inefficient shocks reduces household welfare. As
a result, the optimal policy is characterized by systematic deviations of the interest rates
from the policy rule with a unique optimal variance that maximizes household welfare.Esta tesis estudia la conducción óptima de la política monetaria en presencia de fricciones
nominales e informativas. El primer capítulo estudia la política ´optima en un modelo de
economía pequeña y abierta con tenencia de activos externos. Muestro que la política
óptima implica una volatilidad moderada de la inflación con una inflación interna anticíclica en relación con la inflación externa. El segundo capítulo estudia los determinantes
de la dolarización financiera y la política óptima en las economías emergentes.
Demuestro que la meta de inflación no reduce la dolarización y no es la política óptima.
En cambio, el banco central tiene como objetivo brindar un seguro contra los choques internos
a través de su control sobre la inflación interna. De hecho, en ausencia de fricciones
adicionales, la política óptima logra una distribución eficiente del riesgo entre los hogares
y, al mismo tiempo, elimina por completo la dolarización. Finalmente, el tercer capítulo
estudia la política monetaria óptima en un modelo neokeynesiano con información incompleta.
En este escenario, la divulgación de información pública sobre choques ineficientes
reduce el bienestar de los hogares. Como resultado, la política óptima se caracteriza por
desviaciones sistemáticas de las tasas de interés de la regla de política con una variación
óptima única que maximiza el bienestar de los hogares.Programa de doctorat en Economia, Finances i Empres
Looking for resource sovereignty in a fragmenting global order: the EU’s response to critical raw materials challenges
No full textThis chapter examines the European Union's (EU) evolving concerns and strategies regarding critical raw materials (CRMs), which are essential for the renewable energy and digital transitions. The COVID-19 pandemic and geopolitical tensions with Russia and China have made the EU aware of the fragility of some of their supply chains. Initially seen mainly as an economic issue, the secure supply of CRMs is now perceived as a geopolitical concern crucial for strategic autonomy. This shift led to the 2024 Critical Raw Materials Act, which includes domestic and external measures such as bilateral agreements with resource exporters and strategic partnerships with politically like-minded countries. These policies were supported by almost all Member States, EU institutions, and groups in the European Parliament. Overall, this case illustrates a move of the EU from unequivocally advocating global free trade to a more protective approach to secure the raw materials vital for Europe's political and economic ambitions.This chapter received financial support from the project “The Emergence of European Sovereignty in a World of Systemic Rivalry: Strategic Autonomy and Permissive Consensus (EUSOV)”, funded by the Ministry of Science and Innovation of Spain (Grant number: PID2020-116443GB-I00)
A multiscale spatiotemporal map of protein-RNA assemblies in human cells
No full textRNA metabolism is dynamically orchestrated by RNA-binding proteins (RBPs) in different
subcellular spaces. Aberrant regulation of the subcellular RNA-protein interactions leads
to severe diseases, such as neural degenerations and cancers. Understanding the precise
spatiotemporal dynamics of RBPs and their interacting networks in the steady state and
upon perturbation is key to deciphering the cell function. We present the coRIC
(compartmentalized RNA Interactome Capture) map, an experimental resource and
analytical pipeline to study the subcellular dynamics of RBPs through multimodal dataset
integration and machine learning. coRIC map successfully identified 1,768 RBPs, including
previously underestimated RBPs, spanning 14 major subcellular regions. This map offered
us the opportunity to delineate subcellular RBP features, their intermolecular and
intercompartmental relationships. We have also defined the hierarchy of RBP complexes
at multiple scales across the cell, uncovering previously unknown functions of multiple
RBPs, such as IGF2BP1. Application of coRIC under the perturbations of DNA damage
and ALS-related dipeptide repeats uncovered the cRBP dynamic changes in complex
composition and subcellular distribution. Our work provides a new reference for
systematically studying the subcellular RNA-protein interactions, which helps understand
the RBP regulatory networks in RNA biology and disease.El metabolismo del ARN está orquestado dinámicamente por proteínas de unión a ARN (RBP) en
diferentes espacios subcelulares. La regulación aberrante de las interacciones subcelulares entre
ARN y proteínas conduce a enfermedades graves, como degeneraciones neuronales y cánceres.
Comprender la dinámica espaciotemporal precisa de las RBP y sus redes interactivas en estado
estacionario y tras perturbaciones es clave para descifrar la función celular. Presentamos el mapa
coRIC (captura compartimentada de interactomas de ARN), un recurso experimental y un canal
analítico para estudiar la dinámica subcelular de RBP a través de la integración de conjuntos de
datos multimodales y el aprendizaje automático. El mapa coRIC identificó con éxito 1768 RBP,
incluidas RBP previamente subestimadas, que abarcan 14 regiones subcelulares principales. Este
mapa nos ofreció la oportunidad de delinear las características de la RBP subcelular, sus relaciones
intermoleculares e intercompartimentales. También hemos definido la jerarquía de complejos RBP
en múltiples escalas en la célula, descubriendo funciones previamente desconocidas de múltiples
RBP, como IGF2BP1. La aplicación de coRIC bajo las perturbaciones del daño del ADN y las
repeticiones de dipéptidos relacionadas con la ELA descubrió los cambios dinámicos de cRBP en la
composición compleja y la distribución subcelular. Nuestro trabajo proporciona una nueva
referencia para estudiar sistemáticamente las interacciones subcelulares entre ARN y proteínas, lo
que ayuda a comprender las redes reguladoras de RBP en la biología y las enfermedades del ARN.Programa de Doctorat en Biomedicin
Decentralisation and regional cabinet size: the Spanish case (1979-2015)
No full textThis article explores under what conditions regional governments tend to have larger or smaller cabinets. The main contention is that cross-regional variation in cabinet size is partly explained by the dynamics set up by the multilevel system of government, mainly territorial decentralisation, multilevel government (in)congruence or the existence of nationally distinct regions. The hypotheses are tested with a new and original dataset built upon the Spanish case (1979-2015). Findings show that regions with more welfare state policies, especially when the region's economic capacity is high, and nationally distinct regions tend to have bigger executives. In contrast, decentralisation in the form of basic state functions and government incongruence do not have a significant effect. Results have important implications for our understanding of sub-national territorial institutions and their interaction with decentralisation dynamics
Social media as an identity barometer: evidence from the Russia-Ukraine war
No full textThis study investigates how social media data can be used to study shifts in identity, focusing on Ukraine during the Russia-Ukraine war. We analyze VK users' reported language proficiency and the language of tweets and note a significant shift from Russian to Ukrainian during both the early (2014-2022) and later (2022-) phases of the war. Additionally, we observe a positive association at the province level between these language changes and shifts in ethnic identity reported in nationally representative surveys. The findings underscore the effectiveness of social media data in tracking and quantifying shifts in identity
Sentiment-driven LSTM forecasting: leveraging FinBERT, news, and Kalshi market data for S&P 500 price prediction
No full textTreball fi de màster de: Master's Degree in Economics and Finance. Financial Economics Program . Curs 2024-2025Tutora: Victoria VanascoAmidst growing usage of Machine Learning (ML) models for predictive analysis, this thesis employed a sentiment driven LSTM forecast on the S&P 500 stock price. The LSTM networks were augmented with news articles sentiment encoded with FinBERT, historical stock price data and prediction market forecast from Kalshi to improve forecasting accuracy. The models relied on different sentiment features, such as net daily sentiment and mean negative, neutral and positive sentiment score. Additionally different model architectures were employed, achieving an MAE of 57.04 (0.981% error). This aligns with novel research results where LSTM models outperform traditional methods like ARIMA and GARCH.En medio del creciente uso de modelos de aprendizaje automático (ML) para el análisis predictivo, esta tesis empleó un pronóstico LSTM basado en el sentimiento sobre el precio de las acciones del S&P 500. Las redes LSTM se ampliaron con artículos de noticias codificados con FinBERT, datos históricos de precios de acciones y pronósticos de mercado de predicción de Kalshi para mejorar la precisión de los pronósticos. Los modelos se basaron en diferentes características de sentimiento, como el sentimiento neto diario y la puntuación media de sentimiento negativo, neutral y positivo. Además, se emplearon diferentes arquitecturas de modelos, logrando un MAE de 57,04 (0,981% de error). Esto se alinea con resultados de investigaciones novedosos en los que los modelos LSTM superan a los métodos tradicionales como ARIMA y GARCH
RNA-binding proteins mediate the maturation of chromatin topology during differentiation
No full textTopologically associating domains (TADs) and chromatin architectural loops impact promoter-enhancer interactions, with CCCTC-binding factor (CTCF) defining TAD borders and loop anchors. TAD boundaries and loops progressively strengthen upon embryonic stem (ES) cell differentiation, underscoring the importance of chromatin topology in ontogeny. However, the mechanisms driving this process remain unclear. Here we show a widespread increase in CTCF-RNA-binding protein (RBP) interactions upon ES to neural stem (NS) cell differentiation. While dispensable in ES cells, RBPs reinforce CTCF-anchored chromatin topology in NS cells. We identify Pantr1, a non-coding RNA, as a key facilitator of CTCF-RBP interactions, promoting chromatin maturation. Using acute CTCF degradation, we find that, through its insulator function, CTCF helps maintain neuronal gene silencing in NS cells by acting as a barrier to untimely gene activation during development. Altogether, we reveal a fundamental mechanism driving developmentally linked chromatin structural consolidation and the contribution of this process to the control of gene expression in differentiation
Más allá de la paridad de género en el politainment: cuando la información política se convierte en espectáculo televisivo, el androcentrismo persiste
No full textEn un contexto donde la televisión aún es clave como medio de influencia en la opinión pública, y desde un posicionamiento crítico feminista, este estudio explora la perpetuación de los sesgos de género en la comunicación política que se desarrolla en formatos de infoentretenimiento. El objetivo general es evaluar los roles y las funciones de las personas participantes en los debates de actualidad del politainment desde una perspectiva de género. Para ello se adapta un diseño de análisis de contenido a una muestra no probabilística del período comprendido entre enero y mayo de 2024 (más de 35 horas) que cubre tres debates de actualidad política televisiva de formato, contenidos, franja de emisión y cuota de pantalla similar durante la temporada 2023/24: La hora de La 1 (La 1, Corporación Radio Televisión Española, 11,5 % share), La mirada crítica (Telecinco, Mediaset España, 12,3 % share) y Al rojo vivo (La Sexta, Atresmedia, 11,5 % share). El análisis permite detectar la relevancia de las mujeres presentes en estos espacios de debate, dependiendo del rol que ejercen (moderador, tertuliano, relator, fuente, experto, reportero, corresponsal, o especialista). Los principales hallazgos señalan la infrarrepresentación de la mujer en roles clave como el de experta (8,51%), frente a la feminización de otros como el de relatora, (63,16%) sin voz propia en el debate político espectacularizado. Esta desigual distribución en las funciones ejercidas por las mujeres reproduce su exclusión de la esfera pública también en los formatos de politainment, donde la mirada androcéntrica se impone a su participación efectiva como sujetos políticos
TOPLAP Athens: a networked live coding community
No full textTOPLAP Athens, founded in 2021, is the first Greek-speaking live coding community that focuses on artistic and performative aspects of live coding. This paper outlines the community’s formation, goals, and challenges, highlighting its commitment to fostering collaboration and growth in Greek live coding. Despite geographical dispersion, the group maintains regular online meetups and has performed at significant events such as ICLC 2021, 2023, and 2024. There is a primary focus using SuperCollider and OscGroups for networked performances, prototyping networked setups for handling incompatibilities across different operating systems, and forming a heterogeneous rhizomatic network for creative explorations. While rooted in academic research, the community has evolved to emphasize the artistic and performative aspects of live coding, combining scholarly endeavors with practical exploration and creative expression. Organizational hurdles common to decentralized communities are discussed, along with individual approaches within the group. The paper also discusses future vision, including the exploration of interactive AI and polyglot (i.e. multilingual) live coding performance
