Percepcions i efectes de la representació de la dona gitana als mitjans de comunicació
No full textTutora: Lorena Gómez PuertasTreball de fi de grau en Periodisme. Curs 2024-2025Aquest estudi se centra en analitzar les percepcions i els efectes de la representació de la dona gitana als mitjans de comunicació, abordant el fenomen de l’antigitanisme mediàtic. L’objectiu principal és entendre com les dones gitanes valoren la seva imatge als mitjans i com aquesta les afecta en la seva vida quotidiana i construcció d’identitat. La recerca utilitza una metodologia qualitativa basada en entrevistes semiestructurades a deu dones gitanes espanyoles. L’estudi posa el focus en les pròpies veus de les dones gitanes i en la discriminació interseccional que pateixen per la seva condició de gènere. Els resultats
revelen una percepció generalitzada de ser representades de manera estereotipada, associades a la marginalitat i des d’una narrativa que no les representa. Aquesta imatge s’intensifica per la discriminació interseccional i provoca crisis identitàries i episodis de discriminació quotidiana en les membres de la comunitat. L’estudi pretén contribuir a unes pràctiques periodístiques més ètiques, inclusives i representatives de la diversitat gitana.This study focuses on analyzing the perceptions and effects of the representation of Romani women in the media, addressing the phenomenon of anti-Roma media bias. The main objective is to understand how Romani women perceive their image in the media and how this affects their identity construction and everyday lives. The research follows a qualitative methodology based on semi-structured interviews with ten Spanish Romani women. This study highlights the voices of the Romani women themselves and the intersectional discrimination they face due to their gender. The findings reveal a widespread perception of being portrayed in a stereotypical manner, often associated with marginalization and through narratives that do not represent them. This distorted image is intensified by intersectional discrimination and leads to identity crises and daily experiences of discrimination among members of the community. The study aims to contribute to more ethical, inclusive, and
representative journalistic practices that reflect the diversity of the Roma community
Eating men like air: las imágenes de la boca y la sangre en dos traducciones de la poesía de Sylvia Plath
No full textTreball d'investigació/Fi de màster. Director: Dr. Dídac PujolLa obra poética de Sylvia Plath ha sido ampliamente escrutada por la crítica literaria, en buena parte condicionada por su biografía y su muerte. Muchas lecturas insisten en su vida trágica y en la dimensión suicida de su escritura, mientras que otras han explorado con mayor profundidad su imaginario simbólico —cargado de colores, oposiciones y figuras corporales—. Sin embargo, son pocas las investigaciones que se han centrado específicamente en el imaginario sangriento o rojo, y aún menos en su relación con otra imagen central: la boca. El presente trabajo propone una exploración simbólica, cuantitativa y traductológica de este doble imaginario en la poesía de Plath, con el fin de demostrar que la sangre y la boca constituyen núcleos persistentes de una poética del cuerpo femenino, fragmentado, hambriento y mitificado. A través de un corpus anotado y su análisis visual, se rastrea su evolución a lo largo del tiempo y se examina cómo se traducen y reinterpretan estas imágenes en dos versiones contemporáneas al español.Sylvia Plath’s poetic work has been widely examined by literary critics, largely shaped by her biography and death. Many readings emphasise her tragic life and the suicidal dimension of her
writing, while others have delved more deeply into her symbolic imagery—rich in colours, oppositions, and bodily figures. However, few studies have focused specifically on her bloody or red imagery, and even fewer on its connection with another central image: the mouth. This study proposes a symbolic, quantitative, and translation-focused exploration of this dual imagery in Plath’s poetry, to show that blood and the mouth form persistent cores of a poetics of the female body—fragmented, hungry, and mythicised. Through an annotated corpus and its visual analysis, the evolution of this imagery over time is traced, and its translation and reinterpretation in two contemporary Spanish versions are examined
Different sized belts: family strategies against financial shocks
No full textData de publicació electrònica: 30-04-2025When faced with financial shocks, families often combine multiple resources, including savings, networks, public transfers and services, to cover their needs and respond to changing conditions. This paper explores the strategies families with children in Barcelona deploy to respond to financial shocks by analysing interviews with 29 families experiencing difficulties to make ends meet. The paper makes three main contributions to the literature on responses to shocks. First, it provides novel evidence on how and to what extent families’ strategies are shaped by their past trajectories and resources. Second, it introduces a novel technique, event interviews, specifically designed to study family responses to events and identify the resources (both public and private) they rely on. Third, by contrasting the experiences of families with diverse resources, the paper seeks to illuminate some of the mechanisms through which structural constraints shape coping strategies and thus, agency. Understanding family strategies is particularly relevant in the current context framed by the aftermath of the COVID pandemic and the recent increases in energy, food and housing prices that affected the most disadvantaged the most
Privacy preserving face recognition in cloud robotics: a comparative study
No full textReal-time robotic applications encounter the robot on board resources' limitations. The speed of robot face recognition can be improved by incorporating cloud technology. However, the transmission of data to the cloud servers exposes the data to security and privacy attacks. Therefore, encryption algorithms need to be set up. This paper aims to study the security and performance of potential encryption algorithms and their impact on the deep-learning-based face recognition task's accuracy. To this end, experiments are conducted for robot face recognition through various deep learning algorithms after encrypting the images of the ORL database using cryptography and image-processing based algorithms
Newspaper narratives of migration during national elections in Denmark, Spain, and the Netherlands
No full textTreball de fi de màster Estudis Internacionals sobre Mitjans, Poder i DiversitatSupervisor: Carles Roca CuberesThis study examines how migration is portrayed in national newspapers in Denmark, the Netherlands, and Spain during each country's most recent election. Drawing on Policy Narrative Framing and broader framing theories, we conducted a qualitative content analysis of 300 articles, 100 per country, selected through stratified purposive sampling from two national outlets in each country, representing both left- and right-leaning perspectives. Our findings show that, regardless of editorial stance, mainstream media attribute limited agency to migrants, portraying them predominantly as either victims or depersonalised
threats. At the same time, political and institutional actors drive the narrative. This marginalization of migrant voices reduces complex human experiences to policy abstractions and narrows public debate to questions of control or charity, rather than representing migrants as individuals with agency and the capacity to influence the political debate. We also observe that right-leaning outlets primarily emphasize securitization and cultural identity frames, whereas left-leaning outlets tend to foreground humanitarian and policy critique frames
Identification and characterization of novel bat coronaviruses in Spain
No full textThe zoonotic transmission of bat coronaviruses poses a threat to human health. However, the diversity of bat-borne coronaviruses remains poorly characterized in many geographical areas. Here, we recovered eight coronavirus genomes by performing a metagenomic analysis of fecal samples from hundreds of individual bats captured in Spain, a country with high bat diversity. Three of these genomes corresponded to potentially novel coronavirus species belonging to the alphacoronavirus genus. Phylogenetic analyses revealed that some of these viruses are closely related to coronaviruses previously described in bats from other countries, suggesting a shared viral reservoir worldwide. Using viral pseudotypes, we investigated the receptor usage of the identified viruses and found that one of them can use human ACE2, albeit with lower affinity than SARS-CoV-2. However, the receptor usage of the other viruses remains unknown. This study broadens our understanding of coronavirus diversity and identifies research priorities for the prevention of zoonotic viral outbreaks.This research was financially supported the European Research Council (ERC; Advanced Grant (101019724-EVADER to R.S.), the Spanish Ministerio de Ciencia e Innovación (MICINN; grant PID2020-118602RB-I00 to R.S. and J.M.C.), the Conselleria de Educación, Universidades y Empleo (Generalitat Valenciana; grant CIAICO/2022/110 to R.S.), the European Molecular Biology Organization (EMBO; postdoctoral fellowship ALTF 140-2021 to J.Du. and R.S.), and the Sklodowska-Curie Actions (postdoctoral fellowship 101104880 to J.Du. and R.S.).

Roberto Bolaño and the visual imagination: a poetics of the eye
No full textThe eye was a fetish object for the surrealists, a locus of desire, a portal into the unconscious and the irrational. Roberto Bolaño carried Breton’s savage eye into the center of his own poetics, to see anew. In his work we find the eye as symbol and metaphor, its communicating gesture, its visionary capacity to plumb the depths of dreams, that is able to reclaim the raw, primal nature of perception. We also see the opposite, eyes that cannot see, that are obfuscated, that alight on arbitrary surfaces like stains on the wall or ceiling to open the space of imagination. In Bolaño's work the eye functions as an organizing principle that unifies the components of a poetic system. Shifting signifiers that recur and link and emphasize the thingness of Bolaño’s body of work, making it into an object to be contemplated, una figura sembrada de ojos. We suggest a new way of reading Bolaño. To do so, we look at the text, open the imagination to see Bolaño’s poetic system, his recurring pictograms that act as a second-tier language, geometrical figures that spatialize and constellate, the picture that lay embedded in the language. We locate, bracket, and observe examples of Bolaño’s recurring glyphs, which we call “bolañoglyphs” -windows, triangles, the number three, and the eye providentially casting its spell-shadow-screen– and approach this system through a comparison with another similar system though across the intermedial gulf of image and text; that of Miró’s famous miroglyphs. What happens when we read a painting-poem and look at a novel-poem?El ojo era un objeto fetiche para los surrealistas, un locus del deseo. Roberto Bolaño llevó el ojo salvaje de Breton al centro de su propia poética, para ver y mirar nuevamente. El ojo como símbolo y metáfora, su gesto comunicador, su capacidad visionaria para sondear el inconsciente, su capacidad para reivindicar la naturaleza cruda y primigenia de la percepción. El ojo opera como principio organizador que unifica los componentes de un sistema poético recursivo que enlaza y enfatiza el carácter de cosa de la obra de Bolaño, convirtiéndola en un objeto para ser contemplado, una figura sembrada de ojos. Se analiza su sistema poético: una serie de pictogramas recurrentes que actúan como un lenguaje de segundo orden, figuras geométricas que espacializan y constelan la imagen que yace incrustada en el lenguaje. Se localizan, colocan entre corchetes y observan ejemplos de los glifos recurrentes en su obra, aquí denominados «bolañoglifos» --ventanas, triángulos, el número tres y el ojo que proyecta providencialmente su hechizo-sombra-pantalla-- y se compara cómo el sistema de glifos verbales trasladó el sistema de figuras poético-pictóricas de Miró, sus célebres miroglifos.Programa de Doctorat en Humanitat
Unsupervised clustering of patients undergoing thoracoscopic ablation identifies relevant phenotypes for advanced atrial fibrillation
No full textBackground/Objectives: The rate of recurrence after ablation for atrial fibrillation (AF) is considerable. Risk stratification for AF recurrence after ablation remains incompletely developed. Unsupervised clustering is a machine learning technique which might provide valuable insights in AF recurrence by identifying patient clusters using numerous clinical characteristics. We hypothesize that unsupervised clustering identifies patient clusters with different clinical phenotypes, including AF type and cardiovascular morbidities, and ablation outcomes. Methods: Baseline and procedural characteristics of 658 patients undergoing thoracoscopic ablation for advanced AF (persistent, with enlarged left atria, or with previous failed catheter ablation) between 2008 and 2021 were collected. Principal component analysis (PCA) was used as an unsupervised dimensionality reduction technique, followed by K-Means clustering for unsupervised data clustering. The silhouette score was used to determine the optimal number of clusters, resulting in the formation of three clusters. CHA2DS2-VASc score and AF recurrence were not included in the clustering, but were compared between clusters. Moreover, we compared the patients with and without previously established risk factors for AF recurrence for each cluster. Results: Unsupervised clustering resulted in three distinct clusters. Cluster I had a significantly lower rate of AF recurrence than Cluster II, which contained significantly more persistent AF patients than the other clusters. The CHA2DS2-VASc score in Cluster III was significantly higher than in the other clusters. In all clusters, but particularly in Cluster III, the recurrence risk was higher for persistent AF patients and female patients. In Cluster II, the recurrence risk was not influenced by an increased left atrial volume index, unlike other clusters. Conclusions: Using unsupervised clustering of clinical and procedural data, we identified three distinct advanced AF patient clusters with differences in AF type, CHA2DS2-VASc score, and AF recurrence. We found that established risk factors like BMI, AF type, and LAVI vary in importance across clusters.This research and the APC was funded by ITEA4, grant number 21026, and by the European Union’s Horizon Europe research and innovation programme, grant number 101136438

Post-transplant renal anemia: a call to action from a national study in routine clinical practice
No full textBackground: Post-transplant anemia is a prevalent yet often overlooked condition that poses significant risks. Current guidelines consider the same treatment recommendations and goals for these patients as for chronic kidney disease patients not on dialysis. Previous reports demonstrated a lack of awareness and suboptimal management, indicating a pressing need for improvement. We therefore wanted to update the information on post-transplant anemia. We aimed to describe the present state of anemia management, goals and adherence to guidelines within a representative sample of the kidney transplant (KTx) population. Methods: We designed a retrospective nationwide multicenter study including outpatients from eight KTx hospitals. Nephrologists gathered data from electronic medical records encompassing demographics, comorbidities, KTx characteristics and immunosuppressive therapy, and information pertaining to anemia management (laboratory values, previously prescribed treatments and subsequent adjustments). The European statement on the Kidney Disease: Improving Global Outcomes (KDIGO) guidelines was the reference for definitions, drug prescriptions and targets. Anemia occurring within the initial 6 months post-transplantation was classified as early onset. Results: We included 297 patients with post-transplant anemia aged 62.8 years (standard deviation 13.6), 60% of whom were male. They had received a graft from cardiac death or brain death donors (61.6% and 31.1%, respectively) a median of 2.5 years (0.5-8.7) before. Among them 77% (n = 228) were classified as having late post-transplant anemia, characterized by a higher prevalence of microcytic and iron deficiency anemia. A total of 158 patients were on erythropoietic-stimulating agents (ESAs) treatment, yet surprisingly 110 of them lacked iron supplementation. Notably, 44 patients had an indication for iron supplementation and among them, 30 exhibited absolute iron deficiency. Out of the 158 patients receiving ESAs, only 39 surpassed the limit for the ESA resistance index, indicating poor response. This resistance was more frequent among patients with early post-transplant anemia (26.1% vs 9.2%). We have identified iron profile, early post-transplant anemia and estimated glomerular filtration rate as factors associated with the highest risk of resistance. Conclusion: We found that hemoglobin targets are individualized upwards in post-transplant anemia. In this setting, iron therapy continues to be underutilized, especially intravenous, and iron deficiency and prior events (blood transfusion or hospital admission) explain most of the hyporesponsiveness to ESA. This highlights missed opportunities for precise prescription targeting and adherence to established guidelines, suggesting a need for improved management strategies in post-transplant anemia patients
