Els homes invisibles: els pescadors i llurs famílies a les comarques de l’Alt i el Baix Empordà, la Selva i el Maresme durant els anys trenta
El present treball pretén demostrar com els pescadors formen part d’un grup separat de la resta de la societat quant a la seva manera d’operar i de prendre partit en moments rellevants dels anys trenta. Intentarem esbrinar ...
Sexual (Mis) Encounters in the Mariana Islands: Tracing Sexuality in Spanish Policies and CHamoru Responses to Contact and Colonization, 1521-1769
This doctoral thesis explores the role that sexuality played in the first contacts between the inhabitants of the Mariana Islands (Micronesia, western Pacific) and the Europeans, as well as in the subsequent Spanish ...
For a Marxist Critique of Late Imperialism: Revolution or Extintion
El presente trabajo se divide en dos partes. La primera parte está dividida en dos secciones distintas, mientras que la segunda tiene dos más. La primera sección de la primera parte trata del estado del arte. En particular, ...
Lagragian duality for efficient large-scale reinforcement learning
Reinforcement learning is an expanding field where very often there is a mismatch between the high performance of the algorithms and their poor theoretical justification. For this reason, there is a need of algorithms ...
Natural language processing technologies in compensatory supports for people with aphasia and acquired reading impairments
Aphasia is often associated with reading impairments. Nonetheless, supports designed for people with aphasia and acquired reading impairments allowing autonomous access to written material are lacking. These individuals ...
Involvement of the prefrontal cortex-limbic pathway in the development of food addiction
Food addiction is closely associated with eating disorders including obesity and binge eating. However, the neural alterations underlying this disorder have not been yet clarified. We have trained mice in an operant model ...
Biophysical mechanisms of phagocytic epithelial tissue clearance in the early vertebrate embryo
Cellular errors can spontaneously occur during vertebrate embryo development and can lead to apoptosis. Recent work in our lab revealed a novel function of the embryonic epithelium as an efficient phagocytic scavenger of ...
Dynamics of axial polarization in embyonic stem cells aggregates and the evolution of body axis establishment
Across metazoans, minimal in vitro systems from embryonic stem cells (ESCs) recapitulate the establishment of a body plan, particularly the anteroposterior (AP) axis. In contrast to actual embryos that generally require ...
From populations to species : Unravelling the unknowns of ageing with two complementary approaches
Ageing is a very complex phenotype that has been widely studied, but is still largely unknown. Most of the studies focus on a single species, or on performing genome wide association studies in human cohorts, but this only ...
Representation learning for music classification and retrieval: bridging the gap between natural language and music semantics
The explosion of digital music has dramatically changed our music consumption behavior. Massive digital music libraries are now available through streaming platforms. Since the amount of information available to ...
Motivations, engagement, and incentives in online communities: contributions to theory, data analytics and design
The success of an online community depends on the contributions and actions performed by the community members. This dissertation aims to understand the dynamics of participation in regulated, not-for-profit, open online ...
¿Guerra de Cortes en Costa Rica?: los conflictos entre las jurisdicciones constitucional y electoral
La investigación trata acerca de los principales motivos causales para el surgimiento de los más importantes y recientes conflictos entre la Sala Constitucional y el Tribunal Supremo de Elecciones costarricenses, dos de ...
Intercambio de información policial y protección de datos personales en Europa: ADN forense en la investigación criminal
El intercambio de información entre los distintos cuerpos policiales favorece la cooperación entre Estados cuando se trata de luchar contra el crimen, pero a veces puede afectar al derecho a la protección de datos de ...
In-depth exploration of the syntactic capabilities of autoencoding language models for downstream applications
Pretrained Transformer-based language models have quickly replaced traditional approaches to model NLP tasks, pushing the state of the art to new levels, and will certainly continue to be very influential in the years ...
Generalized exterior-algebraic electromagnetism in (k, n)-dimensional spacetime
This doctoral thesis aims to find a connection between two different disciplines. On the one hand, the electromagnetic theory, one of the most known and most applied theories in physics, properly described by the famous ...
Prácticas comunicacionales activistas en defensa ecoterritorial frente a la megaminería en la Amazonía del Ecuador
Esta tesis por compendio de publicaciones presenta el análisis de las prácticas comunicacionales, como parte de los repertorios de acción colectiva de las redes activistas frente a la intrusión de la industria extractiva ...
Impacto de la disfunción muscular y de los microorganismos resistentes en las exacerbaciones de la enfermedad pulmonar obstructiva crónica
La Enfermedad Pulmonar Obstructiva crónica (EPOC) presenta afectación pulmonar y sistémica y periodos de exacerbación (AEPOC), que contribuyen a su progresión. En algunas ocasiones la AEPOC está causada por microorganismos ...
Computational studies of DNA modifications and mutations in bulk and single-cell data
Sequencing technologies have recently evolved and generated large amounts of data. These datasets have had significant impacts in the cancer field and the detection of damage and repair mechanisms. Methodologies to analyze ...
Adecuación automática de términos biomédicos para personas no expertas: el caso de los informes médicos
La terminología utilizada en los textos médicos especializados pone en desventaja al paciente, quien no siempre logra comprender lo que lee pues carece del conocimiento necesario. La presente tesis doctoral describe una ...
Mechanical control of nuclear plasticity and mechanotransduction in cell migration
Cells commonly live in a crowded environment, in a tissue or in a developing embryo. The extracellular matrix and/or surrounding neighboring cells can impose physical deformations to which cells need to adapt in order to ...
