Authors: Costa Yasmim Silva Blard da , Piveti Gabriel Santos , Silva Kaio de Oliveira Ermida da , Ferraz Rodrigo de Sousa Campista
Published: December 2023

Este artigo buscou propor uma solução que aborda uma lacuna relacionada à deficiência nos procedimentos de manutenção em painéis elétricos. Deficiência essa, causada principalmente pelo monitoramento ineficiente de painéis elétricos, podendo resultar no descuido em relação a portas abertas e à vedação inadequada, gerando consequências graves ao processo. O estudo colheu dados relacionados a um significativo impacto financeiro registrado em uma mineradora, que por conta da deficiência citada, teve sua produção interrompida por mais de 34 horas. Sendo assim, o projeto apresentou uma solução que buscou envolver equipamentos e componentes de automação e controle já existentes nos painéis desta mineradora como CLP, IHM e sensores mecânicos. Além disso, foram detalhados os procedimentos necessários para que essa implantação seja bem-sucedida, já que com os resultados positivos nos testes realizados, houve uma previsão de que a solução agregaria uma significativa mitigação do impacto financeiro e operacional para todo o processo da mineradora, além da adequação à norma NR-12 que se refere à segurança no trabalho em máquinas e equipamentos.
The effect of breed and body weight at slaughter on histochemical muscle fiber characteristics and meat quality of longissimus lumborum and semitendinosus lamb muscles
Authors: Rant Witold , Radzik-Rant Aurelia
Published: December 2023

Abstract. The skeletal muscles of mammals are composed of fibers of different morphological, metabolic and functional characteristics. The properties of muscle fibers may be determined genetically as well as by environmental factors such as the age of the animals, their physical activity, the level of nutrition, or the selection intensity. The present study was conducted to determine the influence of genotype (Polish Lowland vs. Polish Heath) and body weight at slaughter (23–25 kg vs. 35–40 kg) of lambs on histological characteristics of muscle fibers in musculus longissimus lumborum (LL) and musculus semitendinosus (ST) skeletal muscles and their impact on chosen meat quality features. Three types of muscle fibers were identified: slow-twitch oxidative (STO), fast-twitch oxidative (FTO) and fast-twitch glycolytic (FTG). Differences in the diameters of individual fiber types between the LL and ST muscles have been found in both investigated genotypes. The diameters of the analyzed types of fibers were usually larger in the ST muscle compared to the LL muscle. The lambs of the more primitive Polish Heath breed were characterized by a smaller diameter of all fiber types, especially in the LL muscle. The higher proportion of STO fibers and the lower proportion of FTO fibers have been found in the LL muscle of Polish Heath lambs in the group with lower body weight. The breed of lambs, muscle type and slaughter body weight had an impact on some meat quality characteristics, especially color, intramuscular fat content and expressed juice.

Published: December 2023

Abstract. Climate change poses a significant threat to humans and biodiversity, impacting various aspects of livelihoods, infrastructure, and ecosystems. Understanding climate change and its interaction with the environment is crucial for achieving Sustainable Development Goals. Local Climate Zones (LCZ) play a key role in comprehending climate change by categorizing urban areas also based on their thermal characteristics. This study presents prototype open-source software tools developed to integrate ground and satellite data for LCZ analysis in the Metropolitan City of Milan (Northern Italy). These tools consist of a QGIS plugin to access and preprocess ground-based meteorological sensor data and a client-server platform, based on the Open Data Cube and Docker technologies, for the exploitation of multispectral and hyperspectral satellite data in LCZ mapping and analysis. The tools’ architecture, data retrieval methods, and analysis capabilities are described in detail. The QGIS plugin facilitates the access and preprocessing of ground-based sensor data within the user-friendly QGIS environment. The platform enables seamless ground-sensor and satellite data management and analysis, using Jupyter Notebooks as an interface to support programmatic operations on the data. The proposed tools provide a framework for studying climate change and its local impacts on urban environments, with the potential of empowering users to effectively analyze and mitigate its effects.
YUTO SEMANTIC: A LARGE SCALE AERIAL LIDAR DATASET FOR SEMANTIC SEGMENTATION
Authors: Yoo S. , Ko C. , Sohn G. , Lee H.
Published: December 2023

Abstract. Creating virtual duplicates of the real world has garnered significant attention due to its applications in areas such as autonomous driving, urban planning, and urban mapping. One of the critical tasks in the computer vision community is semantic segmentation of outdoor collected point clouds. The development and research of robust semantic segmentation algorithms heavily rely on precise and comprehensive benchmark datasets. In this paper, we present the York University Teledyne Optech 3D Semantic Segmentation Dataset (YUTO Semantic), a multi-mission large-scale aerial LiDAR dataset specifically designed for 3D point cloud semantic segmentation. The dataset comprises approximately 738 million points, covering an area of 9.46 square kilometers, which results in a high point density of 100 points per square meter. Each point in the dataset is annotated with one of nine semantic classes. Additionally, we conducted performance tests of state-of-the-art algorithms to evaluate their effectiveness in semantic segmentation tasks. The YUTO Semantic dataset serves as a valuable resource for advancing research in 3D point cloud semantic segmentation and contributes to the development of more accurate and robust algorithms for real-world applications. The dataset is available at https://github.com/Yacovitch/YUTO_Semantic.

Published: December 2023

Abstract. The availability of semantic information about a cityscape is essential for understanding and analysing urban processes. Automatic gathering of such information is important due to the enormous amount of data. A great number of building features could be gained solely by visual inspections. Therefore, it is meaningful to utilize recent advancements in automatic image recognition technologies to extract these properties automatically.This paper proposes an optimized solution for the classification of rooftops from aerial imagery based on a deep learning model using Convolutional Neural Networks (CNNs). It describes the architecture of the network, the training procedure and important hypermeters. A model analysis using advanced interpretability and explainability tools is conducted. The model’s superiority is demonstrated by comparing its performance against several state-of-the-art image classification architectures, including CNN-based ones such as Xception and Efficientnet, pure Visual Transformers (ViTs) based architectures such as BEiT, and hybrid architectures.
DEVELOPING COMPLETE URBAN DIGITAL TWINS IN BUSY ENVIRONMENTS: A FRAMEWORK FOR FACILITATING 3D MODEL GENERATION FROM MULTI-SOURCE POINT CLOUD DATA
Authors: Ismail M. H. , Shaker A. , Li S.
Published: December 2023

Abstract. The proliferation of affordable LiDAR technology and photogrammetry sensors has revolutionized 3D data acquisition in built environments, enabling comprehensive data capture from citywide scales to interior structures. This data can be transformed into digital twins, providing valuable resources for city planners, architects, engineers, and decision-makers. However, current studies often overlook the limitations of real-world point cloud datasets derived from LiDAR systems, which are voluminous, noisy, incomplete, and lacking information, which hinders monitoring, interpretation, and automated analysis. To address these challenges, methods are required to prepare point cloud data, ensuring accurate and reliable 3D representations. This research proposes a detailed framework for point cloud data preparation in busy urban environments. It includes precise algorithms, software, and parameter guidelines, allowing for the creation of comprehensive point cloud datasets. The framework has been successfully implemented on datasets acquired in Toronto, converting point cloud data from various platforms and parameters into an integrated dataset. Results demonstrate the framework's effectiveness in producing accurate and complete point cloud datasets for applications such as classification, information extraction, 3D model generation, and smart cities' monitoring and management.
Stochastic stability and the moment Lyapunov exponent for a gyro-pendulum system driven by a bounded noise
Authors: Li Shenghong , Lv Junting
Published: December 2023

Abstract. The stochastic stability of a gyro-pendulum system parametrically excited by a real noise is investigated by the moment Lyapunov exponent in the paper. Using the spherical polar and non-singular linear stochastic transformations and combining these with Khasminskii's method, the diffusion process and the eigenvalue problem of the moment Lyapunov exponent are obtained. Then, applying the perturbation method and Fourier cosine series expansion, we derive an infinite-order matrix whose leading eigenvalue is the second-order expansion g2(p) of the moment Lyapunov exponent. Thus, an infinite sequence for g2(p) is constructed, and its convergence is numerically verified. Finally, the influences of the system and noise parameters on stochastic stability are given such that the stochastic stability is strengthened with the increased drift coefficient and the diffusion coefficient has the opposite effect; among the system parameters, only the increase in k and A0 strengthens moment stability.

Published: December 2023

The shortage of skilled workers in technical and scientific professions, including IT, is more topical than ever in Austria. Despite the best job prospects, interest in apprenticeships, school branches and degree programmes in this field is still low. The urgency for action in STEM education is thus highlighted by high dropout rates in STEM-apprenticeships and STEM-qualifications. Based on the EU project RoboCoop we use the example of Educational Robotics including the basic didactic principle of Computational Thinking to indicate how pupils can be inspired for STEM topics through innovative, interdisciplinary teaching/learning settings, and derive recommendations for teacher training.

Published: December 2023

The change in the curriculum for primary school makes it necessary to prepare (prospective) teachers with the topics of data, probability and combinatorics. In order to design a suitable learning setting for the DaWaKo on the basis of a lesson study research project, the initial situation of the (prospective) teachers must be determined. First results show that the students’ assessment in the three areas mentioned is very low and that they have gained almost no teaching experience and that there is an urgent need for further training in order to realise the methodological and subject didactic repertoire in the implementation of stochastic topics in mathematics lessons at primary level.

A Qualitative Exploration of People Who Have Left Housing First and Returned to Homelessness
Authors: Cole Jennie Ann
Published: December 2023

This article offers a thick, rich, multidimensional, and situational look into a Housing First (HF) program in Charlotte, North Carolina, called HousingWorks. This study focuses on individuals who have experienced chronic homelessness and who exited permanent supportive housing (PSH) programs that employ a HF model and return to homelessness. In January 2022, there were 582,500 people experiencing homelessness in the United States (The U.S Department of Housing and Urban Development [HUD], 2023). One-third of these individuals had patterns of chronic homelessness, which has doubled since 2016 (HUD, 2023). Additionally, one-third of unsheltered individuals are at a high risk of being unsheltered again. To address issues of chronic homelessness, emphasis has been placed on increasing supportive housing, which combines permanent affordable housing with supportive services (permanent supportive housing), commonly called a housing first, or the rapid rehousing approach. Participants exited HousingWorks for multiple individual and programmatic reasons. All exits in this study were tied to relationships individuals had with friends, family (of choice and biological), romantic partners, case managers, and neighbors. Consumers, providers, and former residents describe their experiences and offer insights for improving housing retention in PSH programs. Implications for implementation and housing first fidelity criteria are also discussed.

Published: December 2023

In the conditions of the globalization of the global economy and the deepening of economic integration, the external debt appears as a unique form of relations between the global economy and individual regions and group of countries. External debt affects a country's creditworthiness and investors' expectations. Such a circumstance creates a unique chain of interdependencies and interconnections between them. There is a situation where "everyone depends and is connected to everyone". It is obvious that foreign debt is a special form of loanable capital, which, as shown by the development indicators of the global economy in the last decade, has a progressive coefficient of other main macroeconomic indicators (GDP, foreign trade turnover, including exports and
imports).

A coleção dos animais taxidermizados do Museu Escolar do Colégio Marista Arquidiocesano de São Paulo
Authors: Ismael Madi Filho José Maurício , Braghini Katya
Published: December 2023

Animais taxidermizados apareceram na escola em meados do século XIX, no âmbito de um processo que culminou na entrada das ciências nos currículos e na difusão do método intuitivo de ensino. Tal metodologia tinha por princípio a utilização de coisas e o desenvolvimento da observação na construção da aprendizagem. A generalização do uso de objetos tornados materiais didáticos incidiu diretamente sobre os animais taxidermizados, que passaram a ser comercializados para a escola. O presente artigo tem como objetivo apresentar a coleção de animais taxidermizados do centenário Colégio Marista Arquidiocesano de São Paulo, analisando esse patrimônio escolar como fonte e como objeto de estudo. Este trabalho está dividido em quatro partes. A primeira apresenta brevemente as coleções de taxidermizados e seu uso para o estudo de História Natural. A segunda versa sobre a percepção do animal taxidermizado como objeto cultural e sua apropriação como material didático. A terceira contextualiza a composição da coleção no histórico do Colégio Marista. Por fim, há a apresentação do acervo propriamente dita, seu perfil e sua composição no museu escolar. As análises presentes neste trabalho estão ancoradas na temática da história da ciência e da cultura material escolar e contam com contribuições de autores como Augustín Escolano Benito, Keith Thomas, Marie-Noëlle Bourguet e Pierre-Yves Lacour. A documentação é composta de livros de História Natural, de documentação administrativa e memorialística e da coleção de taxidermizados encontrada no colégio. Para os aspectos mais gerais, mobilizam-se manuais de taxidermia, relatórios das Exposições Universais, catálogos de empresas comerciais etc. Como resultado, conclui-se que animais taxidermizados foram apropriados em razão de seu valor mercadológico e de seu potencial pedagógico como mediador de saberes e práticas ligados ao ensino de Zoologia. A coleção do Colégio Marista reflete basicamente os biomas brasileiros, e vários de seus artefatos buscam recriar os comportamentos dos animais na natureza.

Using research findings, it was determined that each strain exhibits distinct morphological, biochemical, and tinctorial attributes that are intrinsic to its particular classification. Remarkably, the API test proficiently categorized the subtypes of these strains, achieving an exceptional precision rate of up to 99.8 %. The following strains of microbes have been isolated during this study: E. coli, Salmonella Typhimurium, Staphylococcus spp., and Proteus mirabilis. The results of analyses conducted through the discօ diffusion technique reveal a diverse spectrum of antibiotic resistance profiles among the multiple strains isolated from poultry, encompassing 28 antibiotics originating from Italy. The acquired data are of significant scientific and pragmatic value. This underlines the need for specific emphasis on strains manifesting pathogenic traits, particularly those demonstrating multidrug resistance involving three or more distinct antibiotics. The importance of understanding and managing antibiotic resistance in avian microbial populations is underscored by this imperative.

Effect of retirement on self-rated oral health and dental services use: longitudinal fixed-effects instrumental variable study in 31 countries
Authors: Baumeister Sebastian-Edgar , Wesselmann Hanna , Nascimento Gustavo G , Listl Stefan
Published: December 2023

OBJECTIVE: This study examined the effect of retirement on self-rated oral health and dental services use.

METHODS: Covering 31 countries, we used harmonized panel data from the English Longitudinal Study on Aging (ELSA), Health and Retirement Study (HRS), and the Survey of Health, Aging and Retirement in Europe (SHARE). Data comprised 485 085 observations from 112 240 individuals aged ≥50 years. Official and early retirement ages were leveraged as instruments in a fixed-effects instrumental variable approach.

RESULTS: We found that retirement exhibited a negative effect on self-rated oral health (β = -0.37; 95% confidence interval (CI) -0.44– -0.30) and a positive effect on the propensity to seek dental care (β = 0.56; 95% CI 0.53–0.60). Male retirees showed a stronger decrease in self-rated oral health and increase in dental services use than female retirees. Participants who previously worked in a physically demanding job showed a stronger effect on self-rated oral health. Conversely, participants without a physically demanding job in the past exhibited a stronger retirement effect on dental service use. Compared with other health system clusters, retirement effects on dental services use were stronger in three health system clusters: Belgium, Denmark, Finland, France, Ireland, Luxembourg, The Netherlands, and Sweden; Israel; and the United States.

CONCLUSIONS: Using a quasi-experimental design, we found that transition to retirement lowers self-rated oral health and increases the use of dental services. Retirement effects appeared heterogeneous across sexes, type of previous labor, and health systems.
Droplet dynamics in the presence of gas nanofilms: merging, wetting, bouncing & levitation
Authors: Spritless James
Published: December 2023

Recent advances in experimental techniques have enabled remarkable discoveries and insight into how the dynamics of thin gas/vapour films can profoundly influence the behaviour of liquid droplets: drops impacting solids can “skate on a film of air” [1], so that they can “bounce off walls” [2,3]; reductions in ambient gas pressure can suppress splashing [4] and initiate the merging of colliding droplets [5]; and evaporating droplets can levitate on their own vapour film [7] (the Leidenfrost effect). Despite these advances, the precise physical mechanisms governing these phenomena remains a topic of debate. A theoretical approach would shed light on these issues, but due to the strongly multiscale nature of these processes, brute force computation is infeasible. Furthermore, when films reach the scale of the mean free path in the gas (i.e.  100nm) and below, new nanoscale physics appears that renders the classical Navier-Stokes paradigm inaccurate. In this talk, I will overview our development of efficient computational models for the aforementioned droplet dynamics in the presence of gas nanofilms into which gas-kinetic, van der Waals and/or evaporative effects can be easily incorporated [8,9]. It will be shown that these models can reproduce experimental observations – for example, the threshold between bouncing and wetting for drop impact on a solid is reproduced to within 5%, whilst a model excluding either gas-kinetic or van der Waals effects is ~170% off! These models will then be exploited to make new experimentally-verifiable predictions, such as how we expect drops to behave in reduced pressure environments. Finally, I will conclude with some exciting directions for future work.
Interaction between fast tides and convection with application to giant planets and solar type stars
Authors: Terquem Caroline
Published: December 2023

We propose a new formalism to calculate the exchange of energy between tides and a convective flow when the turnover timescale is larger than the tidal period. We argue that the standard picture, in which the tides are described as a mean shear flow which is damped by fluctuating convective eddies, is inconsistent and should be reversed. In other words, the fluctuations are the tidal oscillations and the mean shear flow is provided by the largest convective eddies. We further argue that, even if energy is intermittently transferred from convection to the tides, it must ultimately return to the convective flow and transported efficiently to the stellar surface on the convective timescale. This is consistent with assuming that energy is locally transferred from the tides to the convective flow. Using this assumption, we obtain values for the tidal dissipation Q factor of Jupiter and Saturn, for the circularization periods of late-type binaries (taking into account the full time evolution of the stellar structure) and for hot Jupiters in good overall agreement with observations.
Internal shear layers in a stratified and rotating fluid
Authors: Dizès Stéphane Le
Published: December 2023

In a stratified and rotating fluid, internal shear layers are systematically generated when an object oscillates at a frequency between the buoyancy frequency and the vorticity of the fluid. In this talk, I first show that these viscous layers have a generic self-similar structure in the limit of large Reynolds numbers. Then, I consider the reflection of these layers on a boundary. I show that a strong meanflow correction is generated close to the reflection point. I provide its asymptotic structure in the limit of large Reynolds numbers according to the boundary inclination. I finally discuss applications of the results in the context of oceanography (tide) and planetary interiors (libration)
GISPerdas: a geographic information system to help water loss management
Authors: Aragão Helder Guimarães
Published: December 2023

Water is one of the main elements of nature and the environment. It is present in various processes in society. Despite its importance, it is known that water is a finite and scarce resource, as most of it on our planet is salty and found in the oceans, therefore, not potable for human use. The majority of available water resources are unfit for human consumption or for use in activities dependent on these resources. Because of this, it is important to combat water losses when distributed through basic sanitation companies. This loss may occur due to water leaks in the pipes of the urban infrastructure of these companies. Currently, there are few existing technological tools that help combat water leaks. In this context, the present project aims to develop a Geographic Information System (GIS), based on free software, one of the main geoprocessing technologies, aiming to provide maps with leak occurrences in a given municipality. This mapping will reduce water losses from the basic sanitation company.

Correlación entre la amplitud de distribución eritrocitaria y los parámetros hematológicos e inflamatorios, en sujetos venezolanos con procesos infecciosos
Authors: Hernández-Guitián Jesús
Published: December 2023

La amplitud de distribución eritrocitaria es un parámetro hematológico que mide la variabilidad del tamaño de los glóbulos rojos y clásicamente se ha utilizado para determinar el origen de las anemias, sin embargo, actualmente se ha asociado a enfermedades no hematológicas. El objetivo de esta investigación fue determinar si existe correlación entre la amplitud de distribución eritrocitaria y los parámetros hematológicos e inflamatorios, en sujetos venezolanos con procesos infecciosos. Fue un estudio piloto, transversal retrospectivo, donde se registraron los valores de velocidad de sedimentación globular, proteína C reactiva y parámetros hematológicos, de 48 sujetos (40,3 ± 16,2 años de edad), que acudieron al servicio de emergencia del Hospital Universitario de Caracas, los cuales fueron divididos según su estado infeccioso en dos grupos: G1 (sin proceso infeccioso aparente asociado) (n=28) y G2 (con proceso infeccioso) (n=20). Se encontró que sólo hubo diferencia estadísticamente significativa en el contaje de glóbulos blancos y la relación neutrófilo/linfocito (p< 0,05) entre G1 y G2; la amplitud de distribución eritrocitaria mostró correlación positiva con la velocidad de sedimentación globular (p< 0,01), la proteína C reactiva (p< 0,05) y la relación neutrófilo/linfocito (p< 0,05) en el G2, mientras que no mostró correlación con ningún parámetro en el G1. Se concluye que probablemente los procesos infecciosos condicionan a que exista correlación positiva entre la amplitud de distribución eritrocitaria y la velocidad de sedimentación globular, la proteína C reactiva y la relación neutrófilo/linfocito. Se sugiere dar continuidad a este estudio con un tamaño muestral mayor.
Varices esofágicas en autopsia médicolegal
Authors: Pineda Montalván Darwin , Sosa Ramón
Published: December 2023

La hemorragia aguda por rotura de várices esofágicas es una de las complicaciones más graves de la cirrosis. Las varices esofágicas son venas anormalmente dilatadas que se encuentran en la parte final del esófago, por las que circula parte de la sangre que en condiciones normales debería pasar a través del hígado. Su dilatación es consecuencia de la dificultad que el hígado enfermo ofrece al paso de la sangre.
El papel de la medicina forense en la investigación de la muerte súbita
Authors: Lucena Joaquin
Published: December 2023

El papel de la medicina forense en la investigación de la muerte súbita es crucial, ya que desde el punto de vista jurídico, como en su forma de presentación, así como el desconocimiento de la existencia de una patología natural o, en su caso, la falta de testigos, hacen que se trate de una muerte “sospechosa”. De ahí que sea el patólogo forense el responsable de determinar su causa precisa. La autopsia puede representar en estos casos la primera y última oportunidad para hacer el diagnóstico correcto de la causa de la muerte, lo cual es de suma relevancia, especialmente para los familiares. A pesar de la relevancia de su estudio, aun se necesita realizar mas investigación, para su mejor comprensión; especialmente la relacionado a la Muerte Súbita no cardiovascular.
Factores que afectan al valor de marca de la universidad de dong thap - investigación basada en los estudiantes
Authors: Giac Tri Nguyen
Published: December 2023

La investigación analiza los factores que afectan al valor de marca de la Universidad de Dong Thap desde el punto de vista de los estudiantes a través de cuatro factores: conocimiento de marca, asociación de marca, calidad percibida y fidelidad a la marca. El estudio utiliza datos primarios mediante encuestas a estudiantes de la Universidad de Dong Thap y 298 respuestas recogidas mediante cuestionarios a través de un muestreo de conveniencia (muestreo no probabilístico). Los datos se analizaron para obtener estadísticas descriptivas, alfa de cronbach y otros análisis (es decir, análisis factorial exploratorio, estimación y pruebas de regresión). Los resultados muestran que los cuatro factores considerados afectaron al valor de marca de la Universidad de Dong Thap, seguidos de otros factores. Así pues, este valor de marca no sólo se ve afectado por las percepciones de los estudiantes, sino también por los servicios de formación. En consecuencia, la investigación pone de relieve las implicaciones prácticas y la dirección sugerente para que el personal directivo construya el valor de marca de la Universidad Dong Thap.
La discriminación de género a través de las metáforas del cristal, una aproximación a la situación de las mujeres en la alta dirección de la administración pública en México
Authors: Solórzano Andrade Cinthya Teresa , Padilla Martínez Albania
Published: December 2023

La problemática abordada en esta inves­tigación radica en la segregación vertical y horizontal, la cual se evidencia en la baja proporción de mujeres que ocupan puestos de dirección en la administración pública en México (APM) que, además, disminuye conforme se va llegando a cargos de máximo nivel. La cultura, los estereotipos de género y la organización y las políticas públicas para la igualdad de género se consideraron como elementos de análisis; se utilizaron las metáforas: suelo pegajoso, techo, muros y acantilado de cristal para explicar las formas en que se presenta la discriminación de género. Uno de los hallazgos que aquí se plantean es que los códigos sociales permean en los compor­tamientos, normas y valores institucionales y, de esta forma, la discriminación de gé­nero se incorpora en los procedimientos organizacionales, lo que infiere en que las mujeres se encuentren en desventaja desde el proceso de reclutamiento. Sin embargo, ésta no es la única limitación, a pesar de que las reformas de ley obligan a los tres órdenes de gobierno a aplicar la paridad de género. El enfoque de investigación es cua­litativo y el tipo de estudio es descriptivo. La unidad de análisis es la administración pública en México. La recolección de datos se realizó a través de cédulas para el análisis documental y las técnicas de análisis son análisis de contenido e inducción analítica. El sustento teórico es la perspectiva de género.
La transversalidad de la perspectiva de género en las políticas públicas para la violencia intrafamiliar en México
Authors: López Pérez Nadxilli , Jaramillo Cardona Martha Cecilia
Published: December 2023

Este trabajo busca analizar la transversa­lidad de la perspectiva de género en las políticas públicas para la violencia familiar en México, en el período de 2005-2015, a partir de los indicadores del Mecanismo de Seguimiento a la Convención de Belém do Pará (MESECVI), para el monitoreo de las políticas públicas, y la conceptuali­zación de mainstreaming gender, propuesta por García Prince (2008). Se utiliza una metodología cualitativa con base en el método de estudio comparado. Para la comparación se toma como referencia los indicadores de proceso de la MESECVI en los estados de Baja California, Chi­huahua, Guerrero y Tabasco, considerados como muestra por sus altos índices de violencia, de acuerdo con la Encuesta Nacional sobre la Dinámica de las Re­laciones en los Hogares (ENDIREH) 2016 del Instituto Nacional de Estadís­tica y Geografía (INEGI). Se concluye que, de acuerdo con lo establecido por el MESECVI, las entidades federativas de referencia implementan la transversalidad con perspectiva de género en el modelo de prevención, atención y protección, sanción y restitución.
El activismo sexopolítico en Cuba: Apuntes para un debate
Authors: Aguila Sánchez Julio César
Published: December 2023

En el ensayo analizo el contexto del acti­vismo por los derechos sexuales en Cuba; para ello, expongo brevemente las condi­ciones históricas, ideológicas y culturales que actúan como base de la discriminación sexual en el país; después, describo el ac­cionar activista de los últimos treinta años para hacer frente a dicha discriminación y de la apropiación del espacio público por las personas no heterosexuales, como materialización de una conquista; para el cierre, presento las principales críticas que ha recibido dicho activismo. De esta manera, llego a la conclusión de que las críticas hacia el activismo sexopolítico cubano parten de la tradición homofóbica del país y de la oposición al gobierno, por ser un activismo institucionalizado gubernamentalmente que, no obstante, muestra avances significativos en la lucha por el respeto e inclusión en los espacios públicos, laborales, jurídicos y políticos.
