No full textEn agosto de 2023 comenzó en nuestro Hospital un proyecto que contempla un problema real en la comunidad sorda, surgiendo la necesidad de dar respuesta a esta problemática, postergada e invisibilizada por años como ser la inclusión de personas sordas. La comunidad hospitalaria (pacientes, padres, empleados) también precisa dar una respuesta eficaz a esta necesidad comunicativa, para lo cual brindar las herramientas de comunicación básicas, demostrando el máximo respeto hacia la Cultura e Identidad sorda.
En marzo de 2025 inició, a cargo de Enfermería, el dictado del tercer curso destinado a estudiantes del H.I.A.E.P. “Sor María Ludovica”
Resultados preliminares sobre la validez de contenido basada en el juicio de expertos para una escala de observación del vínculo madre-bebé en lactantes con síndrome de Down
No full textIntroducción: El vínculo madre-lactante es el que se establece entre la madre y el bebé. Engloba a la comunicación y es el producto de un proceso comunicacional continuo. Para díadas sin dificultades en el desarrollo se utiliza la Escala de Observación del Vínculo Madre-Bebé. Dado que los lactantes con Síndrome de Down (SD) presentan mayores dificultades en el desarrollo, resulta necesario contar con instrumentos específicamente adaptados. El objetivo fue analizar la validez de contenido del perfil 1 de la escala mediante el juicio de expertos, para su uso en díadas madre-lactante con SD entre 0 y 8 meses.
Material y métodos: Se realizó un estudio descriptivo con diseño mixto. Profesionales expertos con experiencia clínica evaluaron cada ítem de la escala según los criterios de suficiencia, claridad, coherencia y relevancia. Además, se recopilaron sugerencias cualitativas. El análisis cuantitativo incluyó el coeficiente V de Aiken por ítem y Kappa de Fleiss por criterio. Para los datos cualitativos se realizó el análisis temático de Braun y Clarke. El procesamiento estadístico se realizó con el software R versión 4.3.1 y SPSS versión 26.
Resultados: Participaron 29 profesionales de diversas disciplinas. La mayoría de los ítems de la escala obtuvieron un V de Aiken ≥ 0,70 con significación (p < 0,05) para suficiencia, claridad, coherencia y relevancia, excepto la función sostén (V = 0,59; p = 0,229). El Kappa de Fleiss indicó concordancia leve en suficiencia (K = 0,19), moderado en claridad (K = 0,59) y sustancial en coherencia (K = 0,61) y relevancia (K = 0,70). El análisis temático identificó ajustes necesarios en todas las dimensiones, especialmente para la función sostén.
Conclusión: El análisis de la validez de contenido basado en el juicio de expertos respalda la revisión y adaptación de la Escala de Observación del Vínculo Madre-Bebé para lactantes con Síndrome de Down.Introduction: The mother-infant bond refers to the relationship established between the mother and her baby. It encompasses communication and is the result of a continuous communicational process. The Mother-Infant Bond Observation Scale was originally designed for dyads without developmental difficulties. Given that infants with Down syndrome (DS) are at increased risk of developing conditions that may compromise their development, it is essential to have instruments specifically adapted to this population. The aim of this study was to analyze the content validity of profile 1 of the scale through expert judgment, for its use with mother-infant dyads with DS between 0 and 8 months.
Materials and Methods: A descriptive study with a mixed-methods design was conducted. Professional experts with clinical experience evaluated each item of the scale according to the criteria of sufficiency, clarity, coherence, and relevance. Qualitative suggestions were also collected. Quantitative analysis included Aiken’s V coefficient per item and Fleiss’ Kappa per criterion.
Qualitative data were analyzed using the thematic analysis approach by Braun and Clarke. Statistical processing was performed using R version 4.3.1 and SPSS version 26.
Results: Twenty-nine professionals from various disciplines participated. Most items obtained Aiken’s V ≥ 0.70 with statistical significance (p < 0.05) for sufficiency, clarity, coherence, and relevance, except for the holding function (V = 0.59; p = 0.229). Fleiss’ Kappa indicated slight agreement for sufficiency (K = 0.19), moderate for clarity (K = 0.59), and substantial for coherence (K = 0.61) and relevance (K = 0.70). Thematic analysis identified necessary adjustments in all dimensions, particularly regarding the holding function.
Conclusion: The analysis of content validity based on expert judgment supports the revision and adaptation of the Mother-Baby Bond Observation Scale for infants with Down syndrome
Research Infrastructures in Citizen Science: State of Knowledge and Taxonomic Framework As a Pathway to Sustainability
No full textCitizen science platforms (CSPs) and citizen observatories (COs) are rapidly expanding research infrastructures (RIs) that support the growth of citizen science. These systems have boosted data collection capabilities and broadened participant engagement across spatial and demographic dimensions. Despite their essential role in advancing citizen science, the current state of knowledge of these infrastructures remains largely unexplored, affecting both theoretical understanding and practical implementation. The study discussed herein addresses this knowledge gap through a systematic review of 474 articles, with in-depth analysis of 72 publications spanning a 15-year period across multiple disciplinary domains. The methodological framework integrates bibliometric analysis with qualitative investigation, utilizing Web of Science and Scopus databases, supplemented by grey literature from Zenodo and Google Scholar. Findings indicate that research in this field has developed across three main waves: technological development and engagement, monitoring systems and openness, and frontiers technologies. This evolution reflects a progression in the CSP body of knowledge from technical documentation to complex socio-technological systems. Analysis of 450 articles identified 98 unique terms referring to CSPs, highlighting conceptual fragmentation. To clarify the landscape of overlapping, we propose a CSP purpose-based taxonomic framework comprising nine platform categories, contributing to a clearer understanding of the CSPs’ role in citizen science. Additionally, our systematic analysis reveals key research trajectories essential for strengthening CSPs and COs as sustainable infrastructures
RDF Graph GPT - Building Knowledge Graphs with Chat GPT
No full textThis paper introduces RDF Graph GPT app as a tool to automatically translate natural language texts into RDF format knowledge graphs using Artificial Intelligence. Throughout its reading we will dissect and elaborate the various aspects of the functionality mentioned above, as well as some more that this app provides such as graph visualization of any RDF format text with the possibility to choose between two graph types. It also presents an overview of the connection with the AI, more precisely Chat GPT, and the prompts structure that leads to the desired results. The app was tested using different types of natural language texts and different prompts in order to make a richer analysis of the results. This evaluation process was made by experts who gave us some conclusions about the scope and limitations of the tool. It has promising results that show us how interesting this task is along with the potential that the resultant app has. This app, then, puts the focus on the IA as a resource on the matter of developing powerful tools for translating natural language texts into structured formats such as RDF.
A very desired task to do automatically due to its implications and applications in the matter of adding semantics to the data
Características clínicas de la esquizofrenia de inicio muy temprano: a propósito de un caso
No full textLa esquizofrenia de inicio muy temprano es un trastorno psiquiátrico poco frecuente. Presenta criterios diagnósticos similares a la población adulta, sin embargo los niños presentan cuadros clínicos con características particulares. El inicio es más insidioso, hay mayor sintomatología premórbida, con etapas poco diferenciadas, menor respuesta al tratamiento, más hospitalizaciones y por lo tanto, peor pronóstico. Cuando la esquizofrenia inicia antes de los 13 años de edad, se asocia con mayor carga genética que en las presentaciones que inician en la adultez y con hallazgos en neuroimágenes similares. Se presenta un caso clínico de un niño de 8 años de edad con sintomatología compatible con esquizofrenia de inicio muy temprano.LVery early onset schizophrenia is a rare psychiatric disorder. It presents similar diagnostic criteria to the adult population, however, children present clinical symptoms with particular characteristics. The very early onset schizophrenia presentation is more insidious, there are greater premorbid symptoms with poorly differentiated stages, less response to treatment, more hospitalizations and, therefore, a worse prognosis. When schizophrenia begins before the age of 13, it is associated with a greater genetic load than presentations that begin in adulthood and with similar neuroimaging findings. A clinical case of an 8-year-old boy with symptoms compatible with very early onset schizophrenia is presented
Atmospheric microplastic accumulation in Ramalina celastri (Sprengel) Krog & Swinscow Thalli: a transplant study across different levels of urbanization
No full textLichens are widely recognized as bioindicators of atmospheric pollution, but studies on their role in monitoring microplastic (MP) deposition remain scarce. This study investigates MP accumulation in natural populations of Ramalina celastri across an urbanization gradient in Luján, Argentina, marking the first report for this species. MP concentrations ranged from 16.54 ± 3.59 MPs g–1 in baseline sites to significantly higher levels in urban zones. Fragments showed a stronger association with urbanised areas compared with fibres. Unlike larger urban centers, no significant trend was observed in MP size with urbanization, likely due to Lujan’s small size, facilitating unrestricted MP movement. Comparisons with global studies revealed consistent patterns of increased MP accumulation near anthropogenic sources, while unique findings highlight the potential of R. celastri as a bioindicator in diverse environments. These results emphasize the influence of urbanization on MP deposition and suggest localized sources as key contributors to fragments, advancing our understanding of MP dynamics. This work underscores the need for standardized methodologies to enhance comparability in future research on terrestrial MP pollution

Web scraping by end users
No full textScraping is a topic studied from various perspectives, encompassing automatic and AI-based approaches, and a wide range of programming libraries that expedite development. As the volume of available web content increases, it becomes increasingly challenging to anticipate end-user requirements regarding what, how, and when to extract data from the web. This challenge is compounded when integrating data from multiple websites, particularly when websites’ search engines dynamically retrieve unavailable data via permanent links. Complex scraping processes, such as these are difficult to develop using generalpurpose programming languages and are challenging to automate with AI-based approaches. Controllability is a crucial aspect of scraping, that is, how end users can make decisions during the scraper specification process, understand information sources, and how the data are ultimately extracted, compiled, and formatted for output. In response, our study presents an innovative end-user approach for specifying scrapers that focuses on seamlessly integrating data from multiple sources. Through this approach and its supporting toolset, we aim to provide users with greater control and transparency over the extraction, integration, and formatting of data, thereby addressing the key concerns in web scraping. The approach and toolset were evaluated and they yielded promising results
SEO y consumo informativo en medios digitales de Argentina
No full textEl presente artículo analiza la percepción de las audiencias sobre las técnicas de optimización para motores de búsqueda (SEO, por sus siglas en inglés) aplicadas en el periodismo digital. A partir de un enfoque que articula los estudios sobre rutinas productivas, el SEO como técnica de visibilidad y los estudios de recepción, se indaga si los públicos reconocen estas estrategias y cómo las valoran en su experiencia cotidiana de lectura de noticias. El trabajo se inscribe en una segunda etapa de investigación: en una fase previa se identificaron y categorizaron diversas técnicas SEO mediante entrevistas en profundidad a periodistas de distintos medios argentinos. En esta instancia, se organizaron grupos focales en diferentes provincias del mismo país, con el objetivo de explorar las formas en que las audiencias interpretan las estrategias de posicionamiento utilizadas por los medios digitales. Metodológicamente, se recurrió a una estrategia cualitativa basada en el análisis temático de las discusiones generadas en los grupos focales. Los resultados permiten observar que las audiencias identifican algunas de las técnicas SEO relevadas, sobre las cuales valoran aquellas vinculadas a la implementación de recursos audiovisuales. Al mismo tiempo que problematizan las técnicas relacionadas a la saturación informativa y homogeneidad en la producción periodística. Este estudio contribuye a un campo poco explorado al visibilizar la mirada de las audiencias en relación con las estrategias algorítmicas de visibilidad, que plantea la necesidad de encontrar equilibrio entre la accesibilidad y calidad periodística.This article analyzes audience perceptions of search engine optimization (SEO) techniques applied in digital journalism. Using an approach that articulates studies on production routines, SEO as a visibility technique, and reception studies, it investigates whether audiences recognize these strategies and how they value them in their daily news reading experience. The work falls into a second stage of research: in a previous phase, various SEO techniques were identified and categorized through in-depth interviews with journalists from different Argentine media outlets. In this phase, focus groups were organized in different provinces of Argentina, with the aim of exploring how audiences interpret the positioning strategies used by digital media.
Methodologically, a qualitative strategy was used based on the thematic analysis of the discussions generated in the focus groups. The results show that audiences identify some of the SEO techniques surveyed, among which they value those linked to the implementation of audiovisual resources. At the same time, they problematize techniques related to information saturation and homogeneity in journalistic production.
This study contributes to an underexplored field by illuminating audiences' perspectives on algorithmic visibility strategies, which raises the need to find a balance between accessibility and journalistic quality
Evaluación integral de aguas subterráneas en la Llanura Pampeana Argentina mediante indices y análisis discriminante
No full textEl propósito de este estudio es contribuir a la gestión integrada de los recursos hídricos, abordando la complejidad mediante la combinación de dos herramientas estadísticas, la construcción de números índice y el análisis discriminante, empleando variables cuantitativas y cualitativas cuyos valores fueron obtenidos mediante análisis de laboratorio y encuestas. El objetivo principal fue desarrollar y aplicar dos índices, evaluando su confiabilidad mediante análisis multivariado, para analizar la gestión del agua en las escuelas rurales del partido de Tandil, Buenos Aires, Argentina. Por un lado, se construyó un índice de calidad del agua basado en parámetros fisicoquímicos y microbiológicos, los cuales se ponderaron y valoraron según el cumplimiento o incumplimiento de la normativa para agua de consumo. Por otro lado, se construyó un índice de manejo del agua a partir de encuestas realizadas a las escuelas, asignando ponderaciones y valores a las variables en función del conocimiento de su relevancia para el manejo. La confiabilidad de ambos índices se evaluó mediante análisis de correspondencia. Los resultados mostraron que, de las veintiséis escuelas analizadas, dieciocho presentaron un índice de calidad del agua clasificado como bueno, mientras que cuatro obtuvieron una clasificación regular y otras cuatro mala. En cuanto al índice de manejo, dieciocho escuelas obtuvieron una calificación alta, mientras que ocho una calificación media. La metodología utilizada permitió identificar factores institucionales y estructurales que comprometen la calidad del agua, demostrando su potencial aplicabilidad a otros estudios ambientales que requieran integrar variables cualitativas y cuantitativas, con un costo reducido en la obtención de datos.The purpose of this study is to contribute to the integrated management of water resources, addressing complexity by combining two statistical tools, The main objective was to develop and apply two indices, evaluating their reliability through multivariate analysis, to analyse water management in rural schools in Tandil, Buenos Aires, Argentina. On the one hand, a water quality index was constructed based on physicochemical and microbiological parameters, which were weighted and valued according to compliance or non-compliance with regulations for drinking water. On the other hand, a water handling index was constructed from surveys carried out in schools, assigning weights and values to variables based on knowledge of their relevance to management. The reliability of both indices was evaluated through correspondence analysis. The results showed that of the twenty-six schools analysed, eighteen had a good water quality index, while four were rated average and four were rated poor. Regarding the handling index, eighteen schools obtained a high rating, while eight obtained a medium rating. The methodology employed allowed the identification of institutional and structural factors that compromise water quality, demonstrating its potential applicability to other environmental studies that require integration of qualitative and quantitative variables, with reduced data collection costs
