La comunicación del propósito corporativo en organizaciones con impacto positivo. Sinergias y comparaciones entre las prácticas de las B Corporations y de las ONG.
No full textSe analiza cómo el propósito corporativo transforma organizaciones con impacto positivo, especialmente B Corporations y ONG. Se demuestra que, a diferencia de la responsabilidad social tradicional, el propósito actúa como una brújula estratégica que guía decisiones, cultura y comunicación. A través de un enfoque comparativo, se evidencian diferencias: mientras las B Corporations integran el propósito desde su modelo de negocio, muchas ONG lo entienden como misión, aunque sin herramientas estratégicas o comunicativas suficientes para hacerlo visible. La coherencia entre lo que se dice y lo que se hace emerge como clave para la confianza pública. Se identifican oportunidades de colaboración entre ambos sectores, y se proponen recomendaciones para que las ONG fortalezcan su propósito, modernicen su comunicación y refuercen su singularidad. La tesis plantea que hablar de “propósito social” puede ayudar a las ONG a diferenciarse y conectar mejor con las nuevas generaciones, promoviendo un impacto más amplio y sostenibleThis doctoral thesis examines how corporate purpose is integrated and communicated within organizations with a positive impact, focusing on B Corporations and non-governmental organizations (NGOs). In a context where companies are called to act as agents of social change, corporate purpose emerges as an evolution of corporate social responsibility and as a strategic axis of corporate communication. Through a qualitative research design structured in four phases (content analysis, horizontal comparison, expert interviews, and triangulation) the study explores the differences and synergies between both organizational models. The findings reveal that while B Corporations are founded with an activated purpose, NGOs face challenges in updating their communication strategies. The research concludes that purpose only generates impact when it is activated, coherently communicated, and connected to action, proposing a framework to enhance the integration and communication of purpose in organizations operating with limited resources.Programa de Doctorat en Ciències de la Comunicaci
La Justicia Transicional “desde abajo” como enfoque de transformación pacífica del conflicto armado en Colombia
No full textLa continuidad del conflicto armado en Colombia a pesar de la implementación de dos modelos de Justicia Transicional (JT), obliga a la revisión del sistema y su enfoque. La pregunta de este trabajo, aunque obvia, no es fácil de responder: ¿qué explica la paradoja de una JT sin transición? Las evidencias apuntan a que el enfoque retributivo explica el limitado éxito del sistema. Éste, hasta ahora, no ha abordado las causas estructurales del conflicto. La JT tiene necesidad de una perspectiva “desde abajo” que ponga en diálogo criterios jurídicos y sociales, para garantizar la resolución pacífica del conflicto. Este enfoque pone en el centro del sistema a las víctimas y se propone plantear las causas estructurales del conflicto en función de una solución jurídica y social que sea eficaz. Esta investigación, metodológicamente documental, se ajusta a los principios de verdad, justicia, reparación y garantías de no repetición.The Transitional Justice system implemented in Colombia faces widespread criticism because it has failed to generate a transition toward peace and development. The paradox of Transitional Justice without transition justifies the adoption of a "bottom-up" approach, in which victims and grassroots activism acquire the centrality they deserve within the system. The findings of this doctoral research, obtained through qualitative research methods, indicate that this practical perspective facilitates the collective construction of peaceful solutions to the armed conflict by addressing its structural causes, while also ensuring territorial, differential, and gender perspectives. The first section structurally examines the conflict, ultimately proposing a causal theory. The second section critiques "top-down" Transitional Justice and describes the "bottom-up" perspective in detail. The third section practically develops this critical approach, highlighting the grassroots activism of several initiatives.Programa de Doctorat en Estudis Internacionals de Pau, Conflictes i Desenvolupamen
Depth Error and Noise Analysis in Multi-frequency Indirect Time-of-Flight Imaging
No full textCompendi d'articles, Doctorat industrialThis PhD thesis investigates the fundamental limitations and performance factors of indirect Time-of-Flight (iToF) camera systems, with a focus on improving phase estimation accuracy and depth reliability. The global objective is to enhance the understanding of error sources in iToF systems and to develop models and methodologies that improve their robustness and precision in both academic and industrial contexts. The research is structured around three main contributions. First, a multi-objective optimization framework is proposed for selecting modulation frequencies in multi-frequency iToF systems. This model simultaneously minimizes phase unwrapping errors and maximizes depth precision, while incorporating constraints such as maximum unambiguous range and frequency limits, adapting to specific application requirements. Thanks to this multi-objective formulation, the proposed optimization model improves the performance over existing methods. Second, the thesis presents a generalized shot noise model for traditional sampling architectures. This model accounts for key system parameters including modulation frequency, signal amplitude, background illumination, integration time and the number of points in the Discrete Fourier Transform. It provides a deeper understanding of noise behaviour. A second order-order error propagation is modelled to get a more accurate phase variance estimation. Third, the analysis is extended to the differential sampling architecture used in commercial sensors, such as those developed by Analog Devices Inc (ADI). This architecture simplifies the analog front-end and removes the DC component of the received light, optimizing the use of the dynamic range of the Analog to Digital Converter. A new shot noise model is derived, showing that phase error is inversely proportional to signal amplitude and directly proportional to background illumination, while remaining independent of the number of points in the Discrete Fourier Transform. Together, these contributions form a unified framework that links frequency design and noise modelling, offering practical tools for optimizing iToF systems. The proposed methodologies have been validated through extensive simulations and experimental data, and have been integrated into the development of next-generation iToF modules at ADI. This work lays the foundation for future research in adaptive frequency selection strategies and enhanced noise mitigation, particularly in environments affected by multipath interference and dynamic scene conditions.Programa de Doctorat en Informàtic

Microwave-Assisted Synthesis of CsPbBr3 Perovskite Nanocrystals for Optoelectronic Applications Resum de la tesi (Anglès)
No full textCompendi d'articles, Doctorat internacionalPerovskite nanocrystals have emerged as outstanding materials for optoelectronic applications due to their tunable composition, bright emission, and tolerance to defects. Among them, all-inorganic CsPbBr3 nanocrystals exhibit exceptional photoluminescence and stability, making them ideal for next-generation LEDs. However, conventional hot-injection synthesis is complex, energy-intensive, and unsuitable for scale-up. This Ph.D. thesis explores microwave-assisted synthesis as a fast, sustainable alternative, enabling precise control of crystal size and halide composition while achieving high photoluminescence quantum yields after purification. The resulting nanocrystals were successfully integrated into LEDs, showing sharp emission, high efficiency, and excellent luminance. A life cycle assessment revealed that microwave synthesis dramatically reduces energy consumption compared to conventional methods, without compromising material quality. Overall, this work demonstrates that microwave-assisted strategies combine performance and sustainability, offering a scalable route for high-quality CsPbBr3 nanocrystals and advancing their integration into practical optoelectronic technologies.Programa de Doctorat en Cièncie

β2-Adrenergic Receptor Modulation of Astrocyte-Neuron Lactate Shuttle During Recognition Memory Formation: Behavioral and Molecular Studies
No full textDoctorat internacionalThis thesis proposes an integrative framework linking noradrenergic neurotransmission with astrocyte-mediated metabolic mechanisms in long-term declarative memory, focusing on object recognition memory (ORM). Recognition memory relies on recollection and familiarity, supported primarily by the hippocampus and perirhinal cortex, respectively. Using the Novel Object Recognition task, the study demonstrates that noradrenaline (NA) critically modulates ORM through β₂-adrenergic receptors (β₂-AR). Behavioral experiments reveal sex-dependent encoding strategies and show that enhancing NA facilitates, while β₂-AR blockade impairs, ORM. At the cellular level, NA induces astrocytic lactate production via β₂-AR signaling, linking neuromodulation to the astrocyte–neuron lactate shuttle (ANLS). Disruption of lactate transport abolishes NA-mediated memory enhancement, whereas exogenous lactate rescues β₂-AR blockade-induced deficits. Collectively, these findings establish astrocytic metabolism as an essential mediator of NA-dependent, non-emotional memory formation.Programa de Doctorat en Psicologi
