Landmark anything: Multi-view consensus convolutional networks applied to the 3D landmarking of anatomical structures
Get PDFAs shape alterations in three-dimensional biological structures are associated to numerous pathological processes, quantitative shape analysis for obtaining phenotypic biomarkers of diagnostic potential has become a prominent research area. In this context, the automatic detection of landmarks on 3D anatomical structures is crucial for developing high-throughput phenotyping tools. This study evaluates the performance of multi-view consensus convolutional networks – originally developed for facial landmarking– in automatically detecting landmarks on three different 3D anatomical structures: the face, the upper respiratory airways and the brain hippocampi. Leveraging magnetic resonance imaging datasets, we trained multiple models and assessed their accuracy against manual annotations, while analyzing the impact of different network hyperparameters on the results.info:eu-repo/semantics/publishedVersio
Puerto Rican Chronicles on the Spanish Civil War. Remains of a Scattered Memory
Get PDFLas noticias sobre la Guerra Civil española tuvieron un enorme impacto en la sociedad latinoamericana y caribeña, generando de inmediato una serie de disputas político-culturales que marcarían el debate público en todo el ámbito hispánico. En el caso de Puerto Rico, no existe hasta la
fecha un trabajo integral dedicado a las crónicas que unos cuantos puertorriqueños, testigos de la
guerra peninsular, enviaron de forma ocasional a determinados medios de la isla o publicaron en
forma de libro una vez que regresaron. Tales crónicas, escritas por voluntarios brigadistas, estudiantes, médicos, políticos, editores y artistas, se hallan esparcidas en las hemerotecas y en libros
descatalogados de no fácil acceso. Recomponer esta memoria dispersa, examinarla y tipificarla
resulta esencial si se tiene en cuenta que, a diferencia de otros países latinos, la prensa puertorriqueña no envió corresponsales de guerra a la península.The news about the Spanish Civil War had an enormous impact on Latin American and Caribbean
society. This led to political and cultural disputes that would mark the public debate throughout
the Hispanic world. In the Puerto Rican case, there is no exhaustive study of the chronicles on the
Spanish Civil War written by Puerto Ricans. The authors, witnesses of the Peninsular War, occasionally sent their work to some newspapers on the island or published it in book form once they
returned. These chronicles were written by brigade volunteers, students, doctors, politicians, editors, and artists. Nowadays, these documents are scattered in newspaper archives and in out-ofprint books that are not easily accessible. It is essential to reconstruct, examine, and typify this
scattered memory because, unlike other Latin American countries, the Puerto Rican press did not
send war correspondents to Spain.info:eu-repo/semantics/publishedVersio
The Emergence and Effects of Sponsors for Women Leaders
Get PDFSponsoring activities are crucial for women leaders' career advancement. We explore who the sponsors of women are, the nature of their sponsoring activities, and how these activities have influenced women careers' advancement. Based on semi-structured interviews with women leaders in France and Spain, we show the importance of combined assistive and appreciative support in sponsoring activities by superiors and by informal networks inside and outside the organization for women leaders in their early- and mid-careers. We show that women in leadership positions are predominantly sponsored by men, which differs from existing literature that advocates for homophilous propensities and the establishment of same-sex sponsoring relationships. We argue for a more structured approach to offering challenging assignments to women at every stage of their careers, and to move toward a constellation of sponsors both within and outside the organization, who can offer diverse sponsoring opportunities to women leaders at various career stages.info:eu-repo/semantics/publishedVersio
Navigating the Technological Landscape in Hospitality: Added Values and Entry Barriers of Technologies 4.0
Get PDFTechnological advancements, particularly Technologies 4.0, have become pivotal in reshaping the hospitality industry thanks to a wide range of new opportunities but knowing when, and how their adoption is beneficial to a company is an arduous task. This uncertainty of whether the investment is worth it or not hinders managers in taking the leap into the future, restraining business performance from reaching its maximum potential. This study investigates the synergistic relationship between the integration of Technologies 4.0 and the hospitality sector’s pursuit of enhanced service quality, operational efficiency, and sustainable growth. Drawing upon an extensive literature review and empirical data, this research aims to shed light on the added values that Technologies 4.0 offer to the hospitality sector, as well as the entry barriers that organizations encounter in their pursuit of technological integration.info:eu-repo/semantics/publishedVersio

Parental exposure to antidepressants has lasting effects on offspring? A case study with zebrafish
Get PDFFish have common neurotransmitter pathways with humans, exhibiting a significant degree of conservation and homology. Thus, exposure to fluoxetine makes fish potentially susceptible to biochemical and physiological changes, similarly to what is observed in humans. Over the years, several studies demonstrated the potential effects of fluoxetine on different fish species and at different levels of biological organization. However, the effects of parental exposure to unexposed offspring remain largely unknown. The consequences of 15-day parental exposure to relevant concentrations of fluoxetine (100 and 1000 ng/L) were assessed on offspring using zebrafish as a model organism. Parental exposure resulted in offspring early hatching, non-inflation of the swimming bladder, increased malformation frequency, decreased heart rate and blood flow, and reduced growth. Additionally, a significant behavioral impairment was also found (reduced startle response, basal locomotor activity, and altered non-associative learning during early stages and a negative geotaxis and scototaxis, reduced thigmotaxis, and anti-social behavior at later life stages). These behavior alterations are consistent with decreased anxiety, a significant increase in the expression of the monoaminergic genes slc6a4a (sert), slc6a3 (dat), slc18a2 (vmat2), mao, tph1a, and th2, and altered levels of monoaminergic neurotransmitters. Alterations in behavior, expression of monoaminergic genes, and neurotransmitter levels persisted until offspring adulthood. Given the high conservation of neuronal pathways between fish and humans, data show the possibility of potential transgenerational and multigenerational effects of pharmaceuticals’ exposure. These results reinforce the need for transgenerational and multigenerational studies in fish, under realistic scenarios, to provide realistic insights into the impact of these pharmaceuticals.info:eu-repo/semantics/publishedVersio
Navigating the landscape of e‑commerce: thematic clusters, intellectual turning points, and burst patterns in online reputation management
Get PDFRecognizing the challenges identified in the vast literature exploring the intellectual landscape of Online Reputation Management (ORM) in the realm of e-commerce, this study performs a quantitative bibliometric analysis, specifically a co-citation analysis using CiteSpace software, to find thematic clusters in a sample of 1136 papers containing 48,385 cited references. This is the first co-citation analysis of ORM literature that cluster the intellectual structure and identifies both the intellectual turning points and burst papers. The results reveal 14 distinct co-citation clusters, each representing a unique thematic structure. An in-depth analysis further characterizes the clusters, ranging from the impact of online reputation on the hospitality industry to frameworks explaining trust formation in e-commerce. Additionally, the study identifies intellectual turning points by assessing betweenness centrality, highlighting four seminal papers that have strongly influenced the field. Furthermore, burst detection analysis uncovers the temporal dynamics of research trends, showcasing the enduring influence of certain clusters and the transient nature of burst patterns. The novelty and importance of the results from the detailed burst detection analysis lie in identifying a significant evolution in research focus over time. Initially, research was concentrated on foundational studies and understanding customer behavior. It then shifted towards practical applications in specific industries, particularly in hospitality and online reviews. In recent years, the emphasis has been on integrating ORM into broader business strategies, especially within e-commerce and the collaborative economy. This research not only contributes to a deeper understanding of ORM, but also serves as a valuable guide for researchers, practitioners, and policymakers in the evolving landscape of online reputation in e-commerce.info:eu-repo/semantics/publishedVersio
The similarities in the speeches of pro-independence leaders in Catalonia and Scotland. Classical rhetoric in presidents Puigdemont and Salmond
Get PDFEl presente estudio aborda el análisis del discurso independentista oficial en Cataluña y Escocia a partir de los fundamentos de la retórica clásica. Los periodos estudiados se han determinado teniendo en cuenta los puntos álgidos para el independentismo que supusieron, por una parte, el referéndum declarado ilegal de 2017 en Cataluña y, por otra, el referéndum sobre la independencia de Escocia, en 2014. La metodología se basa en la retórica clásica, y particularmente en las obras de Aristóteles y Cicerón, así como en el tratado Retórica a Herenio. Se han sometido a análisis los discursos oficiales de los respectivos presidentes de gobierno independentistas, el catalán Carles Puigdemont y el escocés Alex Salmond (n=45). Los discursos presentan relevantes y a veces sorprendentes similitudes, por ejemplo, en cuanto a su género y estructura, aunque también hay algunas diferencias, por ejemplo, en cuanto al logos. El parecido entre los discursos de Puigdemont y Salmond se explica por el hecho de que el hito de ambos políticos es el mismo: la independencia de su territorio. Los discursos del presidente catalán son más agresivos con el estado central que los de su homólogo escocés, en especial por las distintas circunstancias en que se produjeron los referéndums en Cataluña y en Escocia.This study addresses the analysis of the independence speech in Catalonia and Scotland based on classical rhetoric. The periods studied have been determined taking into account the high points for independence that were, on the one hand, the referendum declared illegal in 2017 in Catalonia and, on the other hand, the referendum on Scottish independence in 2014. The methodology is based on classical rhetoric, particularly the works of Aristotle and Cicero, as well as the treatise Rhetoric to Herennius. The official speeches of the respective presidents of pro-independence governments, the Catalan Carles Puigdemont and the Scottish Alex Salmond (n=45), were subjected to analysis. The speeches show relevant and sometimes striking similarities, for example, in terms of genre and structure, although there are also some differences, for example, in terms of logos. The simi-larity between Puigdemont’s and Salmond’s speeches is explained by the fact that the milestone for both politicians is the same: the independence of their territory. The Catalan president’s speeches are more aggressive towards the central state than those of his Scottish counterpart, especially because of the different circum-stances in which the referendums in Catalonia and Scotland took place.info:eu-repo/semantics/publishedVersio
Prototype-based learning for real estate valuation: a machine learning model that explains prices
Get PDFThe systematic prediction of real estate prices is a foundational block in the operations of many firms and has individual, societal and policy implications. In the past, a vast amount of works have used common statistical models such as ordinary least squares or machine learning approaches. While these approaches yield good predictive accuracy, most models work very differently from the human intuition in understanding real estate prices. Usually, humans apply a criterion known as “direct comparison”, whereby the property to be valued is explicitly compared with similar properties. This trait is frequently ignored when applying machine learning to real estate valuation. In this article, we propose a model based on a methodology called prototype-based learning, that to our knowledge has never been applied to real estate valuation. The model has four crucial characteristics: (a) it is able to capture non-linear relations between price and the input variables, (b) it is a parametric model able to optimize any loss function of interest, (c) it has some degree of explainability, and, more importantly, (d) it encodes the notion of direct comparison. None of the past approaches for real estate prediction comply with these four characteristics simultaneously. The experimental validation indicates that, in terms of predictive accuracy, the proposed model is better or on par to other machine learning based approaches. An interesting advantage of this method is the ability to summarize a dataset of real estate prices into a few “prototypes”, a set of the most representative properties.info:eu-repo/semantics/publishedVersio
'Fugir era el més bell que teníem'. Reflexions des de la postmemòria
Get PDFEl present text proposa un parell de reflexions suscitades per la lectura de Fugir era el més bell que teníem. A mig camí entre la ressenya i l’article acadèmic, entre l’elogi i la crítica, el present text no desgrana el conjunt de la novel·la, sinó tan sols algunes idees que m’ha semblat pertinent aprofundir i retòrcer. Les reflexions s’emmarquen en la línia d’investigació sobre ètica i memòria que la Càtedra Ethos-URL desenvolupa des del 2022, però, en últim terme, es justifiquen pel desig de seguir encadenant escriptura sobre la memòria i memòria sobre l’escriptura.info:eu-repo/semantics/publishedVersio
