Hacia la operacionalización del derecho humano a la vivienda adecuada en México: Propuesta de un indicador multifactorial
Authors: Aguilar-Méndez Carlos Emmanuel
Published: December 2024

En el Estado mexicano, el derecho constitucional a la vivienda adecuada enfrenta desafíos significativos derivados de políticas públicas históricamente enfocadas en criterios económicos y neoliberales. La transición de "vivienda digna y decorosa" a "vivienda adecuada", basada en los criterios de la Organización de las Naciones Unidas (ONU), implica integrar dimensiones como seguridad jurídica, habitabilidad, accesibilidad y adecuación cultural, entre otras. Este cambio exige la alineación normativa y la creación de indicadores específicos que permitan medir y evaluar el cumplimiento de este derecho humano. La investigación propone generar un indicador multifactorial que permita la operacionalización de la vivienda adecuada a partir de i) la definición de una base epistémica basada en teóricos de la arquitectura, el urbanismo e instituciones; ii) la definición del marco normativo a escala internacional y nacional; iii) la caracterización de la vivienda en México y iv) la composición de indicadores preexistentes generados por instituciones como el Instituto Nacional de Estadística y Geografía (INEGI), la Secretaría de Desarrollo Agrario, Territorial y Urbano (SEDATU) y el Consejo Nacional de Evaluación de la Política de Desarrollo Social (CONEVAL) y su alineación con la vivienda adecuada con base en la base epistémica propuesta. El indicador considera las siete dimensiones de la vivienda adecuada establecidas por la ONU y articula enfoques cuantitativos y cualitativos para reflejar la complejidad del contexto mexicano. Los resultados subrayan la necesidad de políticas públicas intersectoriales que prioricen las escalas espaciales más allá de la habitabilidad interna, la cohesión social y la sostenibilidad ambiental. La implementación de este indicador propone, además de la evaluación de las políticas existentes, la identificación de brechas y el diseño de estrategias efectivas para garantizar el derecho a una vivienda adecuada, promoviendo así el desarrollo humano integral y la inclusión social.
Nuevos instrumentos de captación de plusvalías: Experiencias en el corredor noroeste del Área Metropolitana Rosario
Authors: Barenboim Cintia Ariana
Published: December 2024

Las ciudades latinoamericanas han atravesado una rápida urbanización, caracterizada por inversiones privadas que avanzan sobre terrenos rurales y regulaciones permisivas, incrementando la valoración del suelo. En el corredor noroeste del área metropolitana de Rosario, Argentina, se ha registrado un crecimiento excesivo y disperso debido al auge económico, particularmente del sector agropecuario y volcado en la industria de la construcción, a principios del siglo XXI. Allí se ofrecieron grandes parcelas con valor paisajístico para nuevas tipologías residenciales. Sin embargo, surge la necesidad de que los municipios financien las inversiones públicas requeridas. La investigación tiene como objetivo analizar los instrumentos de captación de plusvalías del corredor. La metodología se basa en el análisis de contenido de documentos escritos (trabajos de investigación, datos censales, noticias y normativas) y gráficos (imágenes satelitales) para la confección de plano de expansión urbana, sumado a entrevistas semi-estructuradas. Los resultados muestran que se ha triplicado tanto en población y superficie construida. Además, desde 2019, se han implementado mecanismos para captar plusvalías, identificando el monto y destino de los fondos en Funes y Roldán, generado un debate sobre si deberían destinarse en obras públicas o en gastos generales. En suma, la ejecución del instrumento fortalece las finanzas municipales y promueve un desarrollo urbano equitativo, pero requiere una gestión integral y transparente que asegure el acceso a las infraestructuras y equipamientos básicos.

Authors: Ochoa-Portillo Celia Jocelyn
Published: December 2024

El imperativo de la resiliencia urbana pone de relieve la necesidad de un cambio de paradigma en la planificación y el desarrollo urbanos. En lugar de centrarse en las ganancias a corto plazo y el crecimiento económico, las ciudades deben priorizar la sostenibilidad, la equidad y la resiliencia a largo plazo. El Distrito II de la ciudad de Managua es un sector de importancia para la ciudad, con características físicas, naturales, ecológicas y urbanas que lo vuelven atractivo para la aplicación de este estudio. Al no encontrarse una metodología específica para brindar una valoración numérica, pero considerando la basta fundamentación acerca de la temática, se elaboró una propuesta exploratoria que se centra en evaluar la resiliencia urbana, utilizando cinco variables claves: Equipamientos Urbanos, Áreas Verdes y Espacios Abiertos, Infraestructura y Servicios Básicos, Uso de Suelo, y Ecología Urbana, buscan medir cómo estas áreas pueden adaptarse y recuperarse frente a eventos adversos. Los resultados sugieren que en la actualidad el sector tiene una resiliencia urbana intermedia, con fortalezas en algunos componentes, a la vez que se hace necesario adoptar un enfoque holístico que integre la planificación urbana, el desarrollo de infraestructura y la participación comunitaria, con el foco puesto en la creación de un entorno urbano más resiliente y sostenible.

Authors: Cruz-Ramírez Luis Carlos , Rivas-González Gerardo Tomihuatzi , Zárate-Martinez Jorge Fernando
Published: December 2024

La técnica del corte de la piedra en piezas para la construcción se conoce como estereotomía. Este método de construcción fue desarrollado y perfeccionado durante siglos. Ha sido registrado en algunos tratados de construcción, tales como los de Philibert de l’Orme o Alonso de Vandelvira y funcionó para el desarrollo de la geometría descriptiva. Hoy forma parte de la construcción arquitectónica tradicional de fábricas de cantería y su aplicación en gran medida se limita a la intervención de monumentos. No obstante, la estereotomía es una técnica que continúa siendo desafiante por la dificultad práctica. Desde hace un par de décadas, ha recuperado interés nuevamente en la investigación en arquitectura con la implementación de técnicas digitales como el CAD-CAM, para convertirse en lo que hoy se conoce como estereotomía digital. El objetivo en esta investigación fue identificar como modelar y fabricar por medios digitales una bóveda de arista a escala reducida utilizando procesos de manufactura aditiva de bajo costo. Para cumplir este objetivo, primero se modeló digitalmente una bóveda de arista, pasando su despiece digital desde software CAD, y luego, ejecutando un plan de manufactura digital. Para la manufactura, se utilizó un método aditivo, por medio del Modelado por Deposición Fundida (FDM) con filamento de ácido poliláctico (PLA). Este estudio es de utilidad para comprender un tipo de construcciones con una cantidad representativa de ejemplares y tiene aplicación en la construcción arquitectónica contemporánea.

The Crisis of Older Women’s Homelessness: A Case Study of Australia
Authors: Shao Nan
Published: December 2024

This paper explored the growing homelessness issue among older women in Australia, identifying three main contributing factors. Firstly, the lack of houses which are affordable for homeless people, combined with a rapidly aging population, led to a housing crisis that disproportionately affected this demographic. Secondly, persistent gender disparities, including unpaid caregiving roles, restricted access to full-time employment, and lower retirement savings, significantly worsened their financial vulnerability. Lastly, domestic violence emerged as a significant contributor that intensified the housing insecurity faced by older women. The study further examined how homelessness impacted this group, revealing that it resulted in severe physical and mental health challenges while hindering access to vital social services. To address these issues, several solutions were proposed, such as affordable housing programs, tailored rental support, and co-housing initiatives. Additionally, the paper highlighted the need to create housing projects that focus on accessibility, safety, and aging in place. Innovative financing models, including impact investing and housing funds, were recommended as sustainable approaches to fund housing developments aimed at reducing homelessness among older women.
Systmatic Analysis of Magnetic Monopoles History, Current Research, and Advances
Authors: Qin Mu
Published: December 2024

Magnetic monopoles, first posited by Paul Dirac in 1931, are hypothetical particles that carry a single magnetic charge, unlike ordinary dipoles which have both a north and south pole. These particles would introduce a striking symmetry to Maxwell’s equations of electromagnetism and could provide a compelling explanation for the quantization of electric charge, a key aspect of our understanding of particle physics. Dirac’s theoretical framework laid the groundwork for subsequent exploration of monopoles, inspiring decades of experimental efforts to detect them. These efforts have included searches for remnants of magnetic monopoles in ancient deep-sea ferromanganese crusts and attempts to produce them in advanced particle accelerator experiments, such as those conducted at CERN. Recent breakthroughs in condensed matter physics, particularly in the study of spin ice materials, as well as the creation of synthetic Dirac monopoles in Bose-Einstein condensates, have generated new avenues for understanding their properties and potential behavior. Although magnetic monopoles have not yet been observed directly, ongoing research continues to refine theoretical models and experimental techniques, keeping the search at the frontier of modern physics. The pursuit of monopoles remains significant, especially in the context of advancing toward a unified theory of fundamental forces that underpins the universe.
Research on Power Smoothing Control of Grid-Connected High Proportion New Energy Power Systems
Authors: Guo Shunxi
Published: December 2024

With the increasing share of renewable energy in power systems, the construction of an integrated "source-grid-load-storage" system in regions rich in renewable energy and areas with concentrated loads has become an effective way to promote large-scale local consumption of renewable energy. However, under scenarios of high renewable energy integration, the lack of synchronous inertia support in the integrated system poses severe challenges to system frequency stability. Therefore, it is crucial to deeply explore the frequency regulation potential of each component in the "source-grid-load-storage" system. This paper studies the frequency response characteristics of new energy power stations and the demand-side response mechanism. Based on the actual operating conditions of the system and expected fault scenarios, reasonable virtual inertia time constants are set, and a frequency response model of the "source-grid-load-storage" integrated system is established. Furthermore, a new optimized power command is proposed, which combines a moving average filtering algorithm to smooth wind power output fluctuations. Finally, an optimized energy storage configuration method considering resource coordinated operation is studied. The research in this paper provides theoretical support and reference for improving system frequency stability and promoting renewable energy consumption under high renewable energy integration scenarios.

How Democracies Fall: Exploring Historical Collapses and The Popular Appeal of Dictatorship
Authors: Chen Yitong
Published: December 2024

For the past few centuries, democracy has become increasingly dominant as a political system, especially in the West, and has projected itself to the rest of the world, with many believing that it is the best available model that provides economic development and stability. However, democracies have collapsed in the past and given way to autocracy, raising the question of why such failures occur and how sometimes people, through the electoral process, voluntarily enable the rise of dictators. This paper will thus examine historical cases of democratic collapse, particularly the Weimar Republic, and suggest that these failures were not solely due to factors like economic crises or political extremism, but due to the inherent contradictions within its basis of ideologies that make democracies hard to defend during times of crisis as opposed to autocracies. Exploring the reasons behind the failure, this discussion will, at last, apply itself to the current political climate and suggest that although today’s democratic institutions are more resilient and trusted, the potential risks of collapse remain deeply rooted.

Exploring Aerodynamics: The Impact of Aspect Ratio on Paper Airplane Flight Dynamics
Authors: Sun Yiheng
Published: December 2024

Aspect Ratio significantly influences the aerodynamic performance of aircraft, dictating crucial factors such as lift and glide efficiency. This paper investigates the impact of varying Aspect Ratios on the Gliding Angle of paper airplanes, serving as analogs for larger aircraft. Different models of paper airplanes, each with unique Aspect Ratios, are constructed and tested under controlled conditions to measure their aerodynamic responses. The experiment employs video tracking and statistical analysis to precisely gauge the glide angles and correlate these with Aspect Ratios. Results indicate that an increase in Aspect Ratio generally leads to a decrease in the Gliding Angle, suggesting enhanced aerodynamic performance. However, this relationship exhibits complexity beyond a straightforward linear association, hinting at the nuanced interactions between wing geometry and airflow dynamics. Further, the study explores the Lift to Drag ratio, revealing its dependency on the glide dynamics shaped by Aspect Ratio variations. These findings contribute to a deeper understanding of flight mechanics, potentially guiding the design of more efficient gliders and other aircraft by optimizing Aspect Ratios to suit specific flight requirements.
Comparing the Paraphrasing Ability of ChatGPT and Kimi AI in Jane Eyre：a Qualitative Study
Authors: He Xiangyu
Published: December 2024

This study compares the paraphrasing abilities of ChatGPT and Kimi AI in Jane Eyre, based on a linguistic typology standard. Firstly, the data shows a general paraphrasing situation across each facet of the standard, demonstrating the two Large Language Models(LLMs) performed better in their original source languages, English and Chinese. Subsequently, qualitative case studies demonstrate the discrepancy of single quantitative study and delves deeper into the English-Chinese comparison behind the behaviour of the two models, which is analyzed with comparative Linguistics, advanced translation studies and even Literature theories. The results demonstrate that English is more hypotactic, using more variations of words or clause to express compared to Chinese. Chinese, on the other hand, is more paratactic, requiring more modifiers to concretize the same expression. In conclusion, this paper sheds light on and contributes to the linguistic characteristics of the source languages in developing and refining LLMs for NLP tasks. Meanwhile, concerns are raised about the limitations due to the limited case study and translation deviation. Additionally, this paper rasies suggestions for future AI modification and personalizes development of future LLMs and AI.
