A criação de mulheres tradicionais e modernas na ficção literária de Cyro dos Anjos
Authors: Oliveira Geuvana Vieira de
Published: November 2024

No emaranhado dos mitos gregos, onde Aracne e Penélope se entrelaçam entre fios e destinos, a tecelagem se ergue como uma metáfora luminosa para a criação feminina e a resistência ao silêncio imposto pela sociedade patriarcal. Cada ponto tecido por Aracne e cada trama desfeita por Penélope são mais do que meros gestos de habilidade; representam atos de autonomia e rebeldia contra o domínio masculino. Nesse universo simbólico, a arte de fiar, tradicionalmente associada às mulheres, adquire uma nova ressonância no ensaio A Representação Feminina nos Romances de Cyro dos Anjos, de Geuvana Vieira de Oliveira. Aqui, a tecedura transcende sua função prática para se tornar um emblema de criatividade, comunicação e contestação. O estudo de Vieira de Oliveira nos induz a pensar como essa metáfora entrelaça e acende a construção das personagens femininas nas obras de Cyro dos Anjos — O Amanuense Belmiro, Abdias e Montanha — tecendo com sutileza e profundidade seus papéis nas narrativas, tais como bordados intricados que desafiam convenções e exigem reconhecimento. O ensaio examina, assim, a figura feminina sob dois grandes arquétipos: o tradicional e o moderno, desgastando os padrões e tecidos de gênero que moldam nossas histórias.

Published: November 2024

Abstract. In this study, the impact of local oscillator cable movements or drift during VNA measurements using frequency extenders is investigated. A non-reciprocal measurement error caused by alterations of the local oscillator signal in R 900 (WR 10) waveguide measurements from 75 to 110 GHz is observed and systematically analyzed. Furthermore, the theory behind this effect and its implications on measurement results are discussed, as well as possible corrections for both calibrated and raw measurement data.
Effect of terrestrial nutrient limitation on the estimation of the remaining carbon budget
Authors: De Sisto Makcim L. , MacDougall Andrew H.
Published: November 2024

Abstract. The carbon cycle plays a foundational role in the estimation of the remaining carbon budget. It is intrinsic for the determination of the transient climate response to cumulative CO2 emissions and the zero-emissions commitment. For the terrestrial carbon cycle, nutrient limitation is a core regulation on the amount of carbon fixed by terrestrial vegetation. Hence, the addition of nutrients such as nitrogen and phosphorus in land model structures in Earth system models is essential for an accurate representation of the carbon cycle feedback in future climate projections. Therefore, the estimation of the remaining carbon budget is impacted by the representation of nutrient limitation in modelled terrestrial ecosystems; however, it is rarely accounted for. Here, we estimate the carbon budget and remaining carbon budget of a nutrient-limited Earth system model, using nitrogen and phosphorus cycles to limit vegetation productivity and biomass. We use eight Shared Socioeconomic Pathways (hereafter SSP) scenarios and idealized experiments with three distinct model structures: (1) carbon cycle without nutrient limitation, (2) carbon cycle with terrestrial nitrogen limitation, and (3) carbon cycle with terrestrial nitrogen and phosphorus limitation. To capture the uncertainty in the remaining carbon budget, three different climate sensitives were tuned for each model version. Our results show that, overall, nutrient limitation reduced the remaining carbon budget for all simulations in comparison with the carbon cycle without nutrient limitation. Between nitrogen and nitrogen–phosphorus limitation, the latter had the lowest remaining carbon budget. The mean remaining carbon budgets obtained from the SSP scenario simulations for the 1.5 °C target in the non-nutrient-limited, nitrogen-limited, and nitrogen–phosphorus-limited models were 228, 185, and 175 Pg C, respectively, relative to the year 2020. For the 2 °C target, the mean remaining carbon budget values were 471, 373, and 351 Pg C for the non-nutrient-limited, nitrogen-limited, and nitrogen–phosphorus-limited models, respectively, relative to the year 2020. This represents a reduction of 19 % and 24 % for the 1.5 °C target and 21 % and 26 % for the 2 °C target for the respective nitrogen- and nitrogen–phosphorus-limited simulations compared with the non-nutrient-limited model. These results show that terrestrial nutrient limitation constitutes an important factor to be considered when estimating or interpreting remaining carbon budgets and that it is an essential uncertainty in the remaining carbon budgets from Earth system model simulations.
Comparing High-Resolution Snow Mapping Approaches in Palsa Mires: UAS LiDAR vs. Machine Learning

Published: November 2024

Abstract. Snow cover has an important role in permafrost processes and dynamics, creating cooling and warming systems, impacting the aggradation and degradation of frozen soil. Despite theoretical, experimental, and remote sensing-based research, comprehensive understanding of small-scaled snow distribution at palsas remains limited. This study compares two approaches to generate spatially continuous, small-scale snow distribution models in palsa mires in northwestern Finland based on Digital Surface Models: a machine learning approach using the Random Forest algorithm with in-situ measured snow depth data and an Unmanned Aerial System (UAS) equipped with a Light Detection and Ranging (LiDAR) sensor. For the first time, snow distribution was recorded over a palsa using a UAS. The aim is to review which approach is more precise overall and which areas are not represented sufficiently accurate. In comparison to in-situ collected validation data, the machine learning results showed high accuracy, with a RMSE of 6.16 cm and an R2 of 0.98, outperforming the LiDAR-based approach, which had an RMSE of 26.73 cm and an R2 of 0.59. Random Forest models snow distribution significantly better at steep slopes and in vegetated areas. This considerable difference highlights the ability of machine learning to capture fine-scale snow distribution patterns in detail. However, our results indicate that UAS data enables the study of snow and permafrost interaction at a highly detailed level as well. Generally, snow accumulation zones especially at steep edges of the palsas and inside cracks are recognizable, while thin snow cover occurs at exposed areas on top of the palsas. Correspondingly, areas with thicker snow cover at the edges and inside cracks act as potential warming spots, possibly leading to heavy degradation including block erosion. In contrast, areas with thinner snow cover on the exposed crown parts can act as cooling spots. They initially stabilize the frozen core under the crown parts, but then form steep edges and expose the frozen core, leading finally to even more block erosion and degradation.

Published: November 2024

Abstract. Persistent Scatterer Interferometry (PSI) is a powerful Synthetic Aperture Radar (SAR) technique capable of detecting millimeterscale deformation. However, the technique faces limitations related to the observed ground or areas and the phase unwrapping stage. This research proposes an integrated approach to address these limitations by combining multiple images from different sensors. The integrated method aims to provide more coverage and additional data to partially overcome the weaknesses of the PSI technique. The article introduces the proposed integrated approach and provides insights into the workflows required to apply this method on geoenergy projects.
Standardization of Performance Metrics for Benchmarking InSAR Parameter Estimation
Authors: Sica Francescopaolo , Dill Rafael , Schmitt Michael
Published: November 2024

Abstract. Interferometric Synthetic Aperture Radar (InSAR) is a well-established remote sensing technique that enables a precise monitoring of the Earth’s surface. Accurate estimation of InSAR parameters, such as phase and coherence, is critical for deriving meaningful geophysical information. However, there are many challenges in evaluating the performance of different estimation methods. This work aims to standardize performance evaluation metrics to ensure consistent and reliable results across different applications. We address this challenge by examining factors such as the nature of the data (real or simulated), the processing stage of the evaluation, the signal properties under test, and the nature of the metrics (quantitative and qualitative). We emphasize the need for a comprehensive evaluation framework that integrates multiple metrics to assess different properties of the interferometric data. Examples of both simulated and real data are provided to demonstrate performance evaluation. In addition, we outline various metrics and evaluation frameworks to facilitate benchmarking in InSAR parameter estimation.
Baselines for Calculating Crop Water Stress Index in Bean Cultivation

Published: November 2024

Abstract. Efficient irrigation management is vital for conserving water and maximizing productivity, making the crop water stress index (CWSI) a powerful remote sensing tool. CWSI computation requires lower and upper baselines, corresponding to no-stress and severe stress conditions, respectively. This study aims to compare two different methods for determining those baselines. In the empirical method, the non-water-stressed baseline (NWSB) is derived by the linear regression of the canopy-air temperature difference against vapor pressure deficit (VPD) for a well-watered crop. The combined method compares the NWSB coefficients to theoretical expressions to estimate aerodynamic and canopy resistance at potential transpiration. This work used infrared radiometers (IRR) to measure the canopy temperature of bean plants (Phaseolus vulgaris L.) cultivar ‘IAC1850’ under center-pivot irrigation. Since the empirical method is susceptible to fluctuations in meteorological data, an expressive amount of data had to be filtered out. When comparing the two methods, the RMSE is 1.0 °C for the lower baseline and 1.8 °C for the upper baseline. Future studies could use these baselines to provide CWSI maps from thermographic images.
Enhancing Fluvial Modeling and Flood Prediction Accuracy through the Fusion of 3D Point Clouds, Multispectral, and RGB Data

Published: November 2024

Abstract. Floods are among the most prevalent and devastating natural disasters, affecting over 2 billion people worldwide. The increasing frequency and intensity of extreme precipitation events, driven by climate change, increase the vulnerability of communities to flooding. This underscores the urgent need for more accurate and reliable flood prediction and risk assessment models to enhance preparedness and mitigation efforts. In this research, we investigate the critical role of Digital Elevation Model (DEM) resolution in fluvial flood modeling. DEMs are essential for representing the Earth’s surface and are necessary in hydrodynamic simulations used to predict flood behavior. We employed a two-dimensional hydrodynamic model to simulate flood scenarios using DEMs of three different resolutions: 1 m, 5 m, and 25 m. The objective was to determine how variations in DEM resolution influence the accuracy of flood extent predictions. Our findings reveal that higher resolution DEMs, such as those with 1-meter resolution, provide a more precise and detailed representation of the terrain. This level of detail significantly reduces the predicted extent of flooding compared to lower resolution DEMs (5m and 25 m).
Stereo bathymetry to monitor small seasonal agriculture water ponds in ungauged areas

Published: November 2024

Abstract. Small reservoirs represent a critical water supply to farmers across semi-arid regions, but their hydrological modelling suffers from data scarcity and highly variable and localised rainfall intensities. Over 200,000 ancient rainwater harvesting reservoirs (“tanks”) exist across South India, but with their complex history, considerable size variation, and widespread distribution, understanding the hydrological role of these tanks has been difficult. Fortunately, the last decade has seen improvements in sensors and technologies that enhance our ability to assess the hydrological role of these tanks. In particular, high-resolution Digital Elevation Model (DEMs), now much easier to produce, can be used to improve the characterization of tanks and their surrounding watersheds. Here, a high-resolution DEM is created during the lowest reservoir conditions using Pléiades stereoscopy, and along with two global DEMs, compared with volume estimates from a field-derived UAV reference DEM for a set of tanks in South India. This study demonstrates that a Pléiades-derived DEM can capture accurate reservoir geometry and, when simulating water volume, achieves volumetric differences of 2–8% compared to our UAV reference data. The Pléiades-derived-DEM produced an equivalent height bias less than the expected bias for the recently launched Surface Water and Ocean Topography (SWOT) mission. Deriving high-resolution tank bathymetry from space during low-water conditions provides an opportunity to systematically and repeatably measure tank volume. These results are encouraging in efforts to utilize very high resolution DEMs chosen at an appropriate hydrological time, particularly in regions where water management and security is paramount.

Abstract. To achieve a more green city in the shortest possible time, joint work between government and society is necessary and this work intend to contribute with scientific basis to support the expansion of urban greens areas in Bogota DC. We analyzed the spatial and the social distribution of urban greens and their variations inside of Bogotá urban areas, between years 2019 and 2023, based on NICFI-Planet images. The Normalized Difference Vegetation Index (NDVI) was calculated for each monthly cloud-free mosaics over Bogota DC. and a NDVI Maximum Value Composite (NDVI-MVC) image was calculated for both years. The NDVI-MVC images were clustered with the k-means algorithm, generate a binary image with built-ups targets and other urban targets (vegetation and shadows). These images were analyzed with socio-economic data to a better understanding about the social distribution of urban greens. Were observed an environmental injustice, where the benefits of green areas of the human health are allowed for people from middle and upper classes.
Do Family-Friendly Work Conditions Benefit Women in Malaysia?
Authors:   , Mat Pozian Nadirah
Published: November 2024

This research addresses the challenges Malaysian women face in balancing paid work and family responsibilities. We discovered large gaps between the availability and use of eleven different family-friendly work conditions, and only the use of paid maternity leave was associated with better outcomes (higher work participation and lower anxiety) for women. Existing documentation about family-friendly work conditions overuse gendered language and presume gender roles to reinforce traditional divisions of paid and unpaid work. The notion that family-friendly work conditions benefit women and whether policies promote gender equity and social inclusion over economic prioritization deserves ongoing critique.

Background: A radicular cyst (RC), also known as a periapical cyst, is the most common type of odontogenic cyst. It typically develops at the apex of a tooth’s root due to chronic inflammation following pulp necrosis, often resulting from untreated dental caries or trauma. A radicular cyst is commonly found in anterior maxilla, not commonly seen in the mandible. The bilateral symmetrical presentation of this cyst is quite rare. This case report emphasizes the surgical role in the early diagnosis and treatment of such lesions and the overall oral rehabilitation of such mutilated dentition. Case Report: This report describes the case of a 60-yearold healthy African male who presented with a rare case of bilateral symmetrical radicular cyst in the mandibular premolar region along with advanced periodontal disease and hopeless remaining dentition. The patient management comprised surgical enucleation of the cystic sac for histopathologic examination, extraction of associated remaining roots, and total mouth extraction under local anesthesia followed by bone augmentation and implantsupported overdenture prosthesis. This case was followed up at 6, 12, 24 and 36 months. Radiographic analyses revealed complete healing at the sites of the cyst’s enucleation with no signs of recurrence or preapical pathology. Conclusions: This case presented a common condition in an uncommon age group, sex, location, and presentation. It highlights the importance of clinical and radiographic diagnosis and reinforces the role of histopathologic examination. This case also demonstrates the scope of dental management and comprehensive care of a dental patient with a hopeless dentition.

Efectos de la reducción del financiamiento en universidades públicas mexicanas: Análisis pospandemia
Authors: Reyes de la Cruz Virginia Guadalupe , Alvarado Juárez Ana Margarita
Published: November 2024

Este capítulo analiza la situación financiera de las universidades públicas mexicanas en el contexto posterior a la pandemia de SARS-CoV-2 (covid-19), con el propósito de identificar las particularidades de la reducción del financiamiento gubernamental y su impacto en las diferentes funciones de la universidad: docencia, investigación, vinculación y gestión, a partir de la revisión de fuentes oficiales que incluyen documentos gubernamentales, de políticas públicas y artículos científicos publicados sobre el tema; además de las reflexiones como actores inmersos en esta problemática, derivadas de un proceso de investigación acción participativa. Los resultados revelan desafíos financieros significativos que enfrentan las instituciones de educación superior a consecuencia de la suspensión de diferentes programas federales y la disminución de los recursos estatales. Esta dependencia financiera y la insuficiencia de recursos han afectado los procesos de enseñanza-aprendizaje, la investigación, los proyectos de vinculación con la sociedad, la difusión del conocimiento y la capacidad para ofrecer una educación gratuita. Ante este panorama, se subraya la importancia de diversificar las fuentes de ingresos, integrar la colaboración del sector privado, la eficiencia y transparencia en el manejo de recursos y, fundamentalmente, que el gobierno federal y los gobiernos estatales aseguren la sostenibilidad de las universidades públicas mexicanas.
El financiamiento a la educación y la escolarización en México
Authors: Valle Cruz Maximiliano
Published: November 2024

El presente capítulo muestra las tendencias que ha seguido el financiamiento de la educación pública en México entre 1950 a 2023, y cómo se asocia a los ritmos seguidos por la escolarización en función de las tendencias del crecimiento económico. Para ello, el texto se organiza en tres apartados. En el primero, se muestra el modo en que se creó conciencia a partir del México Independiente acerca de la obligación del Estado para organizar y financiar la educación, la cual se expresa en discursos y regulaciones jurídicas. En el segundo, se da cuenta de los ritmos que ha seguido la escolarización desde fines de siglo XIX hasta 2023, y en cómo se manifiesta la intensidad de la escolarización de la población de 3 a 24 años de edad. En el tercero, en función de las estadísticas disponibles, se muestra el modo en que se distribuye el financiamiento por sector público y privado, así como la distribución del gasto federal en educación por niveles educativos, a partir de 1950, como indicio de la relevancia que la política educativa confiere a la escolarización obligatoria de determinados grupos sociales. Con el propósito de entender la discusión contemporánea en torno al financiamiento a la educación en México, se puede ubicar que a partir de la expedición de la Ley Orgánica de la Educación Pública de 1942, en su artículo 3º se definía a la educación como un servicio público en cualesquiera de sus tipos incluida la impartida por instituciones descentralizadas, cuando era impartida por la federación, estados, municipios, y distrito y territorios federales, en tanto que declaraba a la educación impartida por particulares como de interés público; establecía que el Estado estaba obligado a impartir el servicio educativo y a apoyar a los alumnos pobres con becas. El centro de atención estaba en la educación primaria, pues en el artículo 14 de la citada ley se indicaba que el Estado tendría que aumentar progresivamente sus egresos para lograr que la educación primaria fuera totalmente gratuita, incluso, fijaba la obligación de las aportaciones de los tres niveles de gobierno. La discusión en torno al financiamiento de la educación muestra distintos momentos que acentúan la obligación del Estado para organizar e impartir una educación elemental pública y gratuita, ya sea perfilando el sujeto que se quiere educar, ya sea reivindicando que la educación permite obtener mejores ingresos o que contribuye al desarrollo económico; asimismo, transita de la determinación de las fuentes tributarios, de donde provendrían los recursos a la adopción de la argumentación y recomendaciones provenientes del Banco Mundial, respecto de los recursos destinados a la educación que compiten con otras necesidades prioritarias, que están sujetas a la disponibilidad de recursos que, para el caso de la educación superior, se requiere buscar fuentes alternativas, pues se aspira que alcancen un porcentaje del producto interno bruto para garantizar el ejercicio del derecho a la educación.
Escenarios utópicos o distópicos en perspectiva digital

La historia de la civilización refleja la evolución de la cultura humana, caracterizada por transformaciones sorprendentes. Actualmente, nos encontramos en un periodo ‘postécnico’, ligado a la posmodernidad. La interacción entre humanos y técnica ha dado lugar a una nueva forma de artefactualidad, marcada por la inteligencia artificial, que redefine nuestra era tecno-científica. Estamos avanzando hacia realidades transhumanas y poshumanas, buscando desarrollar una inteligencia artificial general que impactará el discurso jurídico contemporáneo. Los sistemas jurídicos actuales están diseñados para un mundo analógico y podrían enfrentar una crisis al convivir con entidades de inteligencia artificial.
El transhumanismo desafía la ciencia jurídica mediante tecnologías NBIC, destinadas a mejorar al ser humano. Además, la creación de máquinas inteligentes o “no-cosas” está cambiando nuestras interacciones sociales. Si estas “no-cosas” adquieren características humanas, podríamos ver un cambio significativo en nuestra concepción de la humanidad y las relaciones sociales.
El papel del Estado subsidiario y las supuestas externalidades negativas
Authors: Mohor Salvador
Published: November 2024

Nuestro propósito es poner de manifiesto la importancia de la subsidiariedad como factor de desarrollo económico y social, y la necesidad de su aplicación como alternativa de ideologías políticas fundadas en la negación de las libertades y en el fortalecimiento indiscriminado del poder del Estado (v. gr. socialismo marxista) como, asimismo, de aquellas que exacerban el goce de las libertades en perjuicio de la justicia social (v. gr. liberalismo individualista). En este plano, intentaremos desactivar las negativas externalidades que se le atribuyen a la subsidiariedad.
