ABSTRACT This study focuses on the performance of cows for meat production raised in the wetlands of Paraguay, examining five cattle genotypes: Brahman, Brangus, and Nelore, as well as two local breeds at risk of extinction. The main objective is to identify and rank phenotypic variables, including blood, clinical, hair, and health variables, demonstrating causal linkage with the live weight of the cows analyzed. Initially, high correlations were identified between different variables included in this study; then, using advanced Machine learning (ML) techniques and the application of Shapley additive explanations (SHAP), a deeper understanding was provided of the factors strongly associated with adaptability in these environments, and, therefore, the respective zootechnical performance. The association between cattle genotypic components linked with the season of the year proved to be the most influential factor on cattle live weight. Variables such as hair length, hematocrit, phosphatase, phosphorus, creatine phosphokinase, creatinine, protein, cortisol, calcium, and the presence of endoparasites were highlighted, demonstrating their hierarchical importance for animal selection. ML models are effective tools for establishing hierarchies of relevance in complex phenotypic multivariable, which is crucial in breeding programs for different zootechnical species and in special and specific environments like wetlands.

RESUMO Este estudo foca no desempenho de vacas para produção de carne, criadas nos pântanos do Paraguai, examinando cinco genótipos bovinos; Brahman, Brangus, Nelore, bem como duas raças locais em risco de extinção. O principal objetivo é identificar e classificar variáveis fenotípicas que incluem variáveis sanguíneas, clínicas, de pelagem e saúde, demonstrando ligação causal com o peso vivo das vacas analisadas. Inicialmente, foram identificadas correlações elevadas entre diferentes variáveis incluídas neste estudo, e, então, utilizando técnicas avançadas de aprendizado de máquina e a aplicação de explicações aditivas de Shapley (SHAP), foi proporcionado um entendimento mais profundo dos fatores fortemente associados à adaptabilidade nestes ambientes, e, portanto, o respectivo desempenho zootécnico. A associação entre o componente genotípico bovino ligado à estação do ano mostrou ser o fator influente mais predominante sobre o peso vivo bovino. Variáveis como comprimento do pelo, hematócrito, fosfatase, fósforo, creatina phosphokinase, creatinina, proteína, cortisol, cálcio e a presença de endoparasitas foram destacadas, demonstrando sua importância hierárquica para a seleção animal. Os modelos de ML são ferramentas eficazes para estabelecer hierarquias de relevância em multivariáveis fenotípicas complexas, o que é crucial em programas de melhoramento genético em diferentes espécies zootécnicas, bem como em ambientes especiais e específicos, como os pântanos. carne Paraguai bovinos Brahman Brangus Nelore extinção sanguíneas clínicas saúde analisadas Inicialmente então SHAP, SHAP , (SHAP) portanto zootécnico pelo hematócrito fosfatase fósforo phosphokinase creatinina proteína cortisol destacadas animal complexas zootécnicas específicos (SHAP

Resumen: Se trata de estudiar, en una primera aproximación, el impacto del cambio en el modo de producción como consecuencia de la telemática y el uso del aprendizaje de las máquinas y la inteligencia artificial en muchas de las aplicaciones y procesos repetitivos en los sistemas sociales de producción y distribución de bienes. Se utilizó el método del construccionismo sistémico, que, en definitiva, parte de la base de que los datos no son datos, sino construcciones con supuestos teóricos inevitables, y de que la lengua es el sistema en el que se construyen los lenguajes que son un límite general para obtener y comunicar información en la sociedad. Esto conduce a una teoría de las acciones algo diferente de las de Parsons y Luhmann, que lleva al concepto de praxemas, y a todo un nuevo análisis de la sociedad y su derecho.

Abstract: The aim is to study, in a first approximation, the impact of the change in the production mode as a result of telematics and the use of machine learning and artificial intelligence in many of the applications and repetitive processes in social systems of production and distribution of goods. The method of systemic constructionism was used, which, in short, assumes that data are not data - they are constructions with unassailable theoretical assumptions and that language is the system in which the general limit languages are constructed to obtain and communicate information in society. This leads to a theory of actions somewhat different from those of Parsons and Luhmann - leading to the concept of praxemas, and to a whole new analysis of society and its law.

Abstract: This study addresses the application of the Cross-Industry Standard Process for Data Mining (CRISP-DM) methodology in the analysis of dissolved gases in oil of power transformers, being this a critical component in electrical systems. The adoption of this six-phase structured method allowed a comprehensive evaluation of the condition of the transformer units of the Ecuadorian electrical system based on the analysis of investment and expansion data of the sector, as well as the study of 1 099 DGA (Dissolved Gas Analysis) profiles obtained from a population of 153 transformers located in the different regions of continental Ecuador. The findings described in this work have the potential to significantly improve investment and maintenance strategies and policies. In addition, the adoption of automation techniques in the DGA classification process is proposed, using supervised learning models to enhance the reliability and efficiency of the public energy service. The results suggest that this approach not only improves the diagnosis within the maintenance activities, but also provides a solid basis to draw a roadmap towards a predictive asset management, resulting in a substantial improvement of the reliability of the national power system.

Abstract The development of mining projects in the exploration and pre-feasibility stages involves challenges related to geological and processing heterogeneity and uncertainty due to variability in their primary and response attributes. Therefore, the objective of this research is to develop the geometallurgical model of the Bond work index. For this purpose, linear regression models were developed in Jupyter Notebook considering 790 samples of uniaxial compressive strength of rock (UCS), lithologies, mineral zones and Bond work index (BWi) in a porphyry copper deposit. The results indicate a directly proportional linear relationship between BWi and UCS, generating modeling with acceptable R2 performances between 0,76 and 0,90. In addition, the lithologies and ore zones in the deposit studied are relevant characteristics related to comminution. Finally, according to rock competence, the rock is classified as medium to hard, hard and very hard in the oxide, mixed and primary sulfide zones, respectively.

This research presents the implementation and evaluation of machine learning models to predict solar irradiance (W/m²). The objective is to provide valuable insights for making informed decisions regarding solar system design and financing. A thorough exploratory data analysis was conducted on the Southern African Universities Radiometric Network (SAURAN) data collected at the University of Pretoria's station to gain insights into the patterns of solar irradiance over the past 10 years. Python's functions and libraries are utilized extensively for conducting exploratory data analysis, model implementation, model testing, forecasting, and data visualization. Random Forest (RF), k-Nearest Neighbors (KNN), Feedforward Neural Network (FFNN), Support Vector Regression (SVR), and extreme Gradient Boosting models (XGBoost) are implemented and evaluated. The KNN model was found to be superior achieving a relative Root Mean Squared Error (RMSE), relative Mean Absolute Error (MAE), and R-Squared (R²) of 5.77%, 4.51% and 0.89 respectively on testing data. The variable importance analysis revealed that temperature (°C) exerted the greatest influence on predicting solar irradiance, accounting for 44% of the predictive power. The KNN model is suitable to inform solar systems design and financing decisions. Directions for future studies are identified and suggestions for areas of exploration are provided to contribute to the advancement of solar irradiance predictions.

RESUMO: A qualidade e a produtividade de um vinhedo estão relacionadas com a biomassa do dossel e o vigor foliar, e técnicas de sensoriamento próximo têm sido utilizadas como alternativas aos métodos convencionais para estimar esses parâmetros. O conhecimento do teor de clorofila é fundamental para as avaliações fitossanitárias. No entanto, índices de clorofila também podem ser extraídos de espectros de refletância obtidos para uma ampla gama de aplicações. Nesta perspectiva, foram investigadas as relações entre os índices de clorofila obtidos por medidas diretas e derivados de radiometria de campo, com o objetivo de avaliar a acurácia do teor de clorofila previsto. A investigação foi realizada em plantas da variedade Cabernet Sauvignon, baseando-se em levantamentos diretos de clorofila, espectrorradiometria foliar e na derivação de Índices de Vegetação Hiperespectrais (HVIs), sendo a aquisição de dados realizada em duas fases do ciclo vegetativo. Os resultados das estimativas mostraram que os maiores coeficientes de determinação expressando a correlação entre medições e predições foram obtidas para Chl a e Chl a/Chl b modeladas pelo algoritmo RFR, com valores de R ² tão altos quanto 0,8 e erros quadráticos médios tão baixos quanto 0,093. Com relação aos HVIs, o Photochemical Reflectance Index (PRI) calculado para a segunda data de aquisição, correspondente às folhas que atingiram a senescência, foi o que produziu o maior percentual de explicações de predição. Em conclusão, sugere-se que este estudo pode trazer uma contribuição significativa para o desenvolvimento de técnicas não invasivas de monitoramento de vinhedos.

ABSTRACT: Quality and yield of a vineyard are related to canopy biomass and leaf vigor, and proximal techniques have been used as alternatives to conventional methods to estimate these parameters. Knowledge on chlorophyll content is crucial to plant health assessments. However, chlorophyll indices can also be extracted from reflectance spectra obtained for an ample range of applications. In this perspective, relations between chlorophyll indices obtained by direct measurements and derived from field radiometry were investigated, with the aim to assess the accuracy of predicted chlorophyll content. The investigation was performed on Cabernet Sauvignon vines, being based on direct chlorophyll surveys, vine leaf spectroradiometry and the derivation of Hyperspectral Vegetation Indices (HVIs), with data acquisition being performed on two stages of the vegetative cycle. Direct chlorophyll data was compared with predicted indices using two machine learning algorithms: Partial Least-Squares Regression (PLSR) and Random Forest Regressor (RFR), using data from reflectance spectra and derived HVIs. The higher correlations between measurements and predictions were obtained for ChlaandChl a/Chl b modeled by the RFR algorithm, with R 2 values as high as 0.8 and Root Mean Squared Errors as low as 0.093. With respect to HVIs, the Photochemical Reflectance Index (PRI) calculated for the second acquisition date, corresponding to leaves reaching senescence was the one which produced the highest percentage of prediction explanations. This study can bring a significant contribution to the development of non-invasive techniques to vine monitoring.

Abstract This article endeavours to examine how Brazilian television has responded to technological trends in the context of media convergence within the realm of Brazilian television, with a specific focus on the streaming platform of Globo Group, the largest media conglomerate in Latin America, known as Globoplay. The central argument of this paper revolves around the various forms of engagement employed by the organisation as it seeks to adapt to the changing landscape of media. Using the case study method (Yin, 2015), this research correlates the theoretical framework with three central points aimed at discussing engagement in the era of media convergence as a foundation for television’s relationships with its advertisers, the creation of audiovisual products and projects, and, most importantly, its relationship with the contemporary audience. The analysis underscores the use of techniques such as artificial intelligence and machine learning, which aid the platform in reshaping its strategies and decision-making processes. In light of the findings and subsequent discussion, it can be inferred that the primary goal of these initiatives is to foster engagement among both its audience and advertisers.

Resumo Este artigo visa examinar como a televisão brasileira tem respondido às tendências tecnológicas no contexto da convergência mediática, com foco específico na plataforma de streaming do Grupo Globo, o maior conglomerado de média da América Latina, conhecida como Globoplay. O argumento central deste artigo gira em torno das várias formas de engajamento empregues pela organização enquanto procura adaptar-se ao cenário de constante mudança dos média. Utilizando o método de estudo de caso (Yin, 2015), esta pesquisa correlaciona o quadro teórico com três pontos centrais destinados a discutir as noções de engajamento na era da convergência dos média como base para as relações da televisão com os seus anunciantes, a criação de produtos e projetos audiovisuais e, sobretudo, a sua relação com a audiência. A análise destaca o uso de técnicas como inteligência artificial e aprendizagem automática, que ajudam a plataforma a remodelar as suas estratégias e processos de tomada de decisão. À luz dos resultados e discussão subsequentes, pode-se inferir que o objetivo principal dessas iniciativas consiste em adaptar-se ao contexto hipertelevisivo e ampliar o modo como o Grupo Globo se relaciona tanto com o seu público como com os seus anunciantes.

Abstract: Following the economic complexity methodology introduced by Hausmann et al. (2013), this study establishes an order of crime evolution in Mexico. This ordering is based on the complexity of crimes, as determined by the capabilities required to commit them. According to the study, the least complex crimes in Mexico include robbery in collective public transport, robbery in individual transport, counterfeiting, and auto parts theft. On the other hand, the crimes characterized by the highest complexity involve organized crime, intentional and unintentional homicide, and the trafficking of minors. Furthermore, the analysis reveals that femicide and rape exhibit the most significant centrality or influence within the criminal network. According to the model, crimes associated with violence against women are those that most increase the probability of committing another crime. Therefore, targeted prevention efforts aimed at reducing femicide and rape may substantially impact overall levels of criminality in Mexico. This study also highlights the importance of addressing violence against women in designing crime prevention policies in Mexico. Moreover, the methodology adopted in this study can be reinterpreted as a spectral clustering algorithm and thus also contributes to the literature on machine learning applications in public policy design.

Resumen: Bajo la metodología de complejidad económica propuesta por Hausmann et al. (2013), esta investigación estableció un ordenamiento de la evolución del crimen en México. Este ordenamiento se basa en la complejidad de los delitos, determinada por las capacidades requeridas para cometerlos. De acuerdo con esta investigación, los delitos con menor complejidad en México incluyen el robo en transporte público colectivo, robo en transporte individual, falsificación y robo de autopartes. Por otro lado, los delitos con mayor complejidad están relacionados con el crimen organizado, el homicidio intencional e involuntario y el tráfico de menores. Además, el análisis reveló que el feminicidio y la violación exhiben la centralidad o influencia más significativa dentro de la red criminal. Según el modelo, los delitos asociados con la violencia contra las mujeres son los que más aumentan la probabilidad de cometer otro delito. Por lo tanto, los esfuerzos de prevención dirigidos a reducir el feminicidio y la violación pueden tener un impacto sustancial en los niveles generales de criminalidad en México. Este estudio también destaca la importancia de abordar la violencia contra las mujeres en el diseño de políticas de prevención del delito en México. Además, la metodología adoptada en este estudio puede ser reinterpretada como un algoritmo de agrupamiento espectral y, por lo tanto, también contribuye a la literatura sobre aplicaciones de aprendizaje automático en el diseño de políticas públicas.

Abstract The current article explores the causes of financial inclusion among the Mexican population. It leverages data from the Encuesta Nacional de Inclusión Financiera (ENIF) (INEGI, 2021) to develop two machine learning models aimed at identifying individuals who are part of the financial system. These models are assessed using both artificial intelligence methodologies and traditional statistical significance tests. The findings suggest that factors such as education level, monthly income, future-oriented behavioral preferences over present ones, saving capacity, and access to smartphones are significant drivers that enhance the likelihood of financial inclusion. Consequently, there is a potential for implementing public policies to incentivize individuals to voluntarily adopt formal financial services.

Resumen El presente artículo explora las causas de la inclusión financiera entre la población mexicana. Con datos de la Encuesta Nacional de Inclusión Financiera (ENIF) (INEGI, 2021) desarrolla dos modelos de aprendizaje automático con el objetivo de identificar a individuos que forman parte del sis tema financiero. Estos modelos son evaluados valiéndose tanto de metodologías de inteligencia artificial como de pruebas estadísticas de significancia tradicionales. Los hallazgos sugieren que factores como nivel educativo, ingreso mensual, preferencias orientadas hacia el futuro sobre las presentes, capacidad de ahorro y acceso a teléfonos inteligentes son impulsores significativos que aumentan la probabilidad de inclusión financiera. En consecuencia, existe un potencial para la implementación de políticas públicas dirigidas a incentivar a los individuos para que adopten voluntariamente servicios financieros formales.

Abstract This paper investigates trends in antiretroviral medication prices and their impact on public health in Mexico during 2019. Using three machine learning models developed in Python (logistic regression, random forest, and K-Nearest Neighbors or KNN), this study discerns increasing or decreasing patterns in antiretroviral (ARV) drug price fluctuations using a dataset comprising 15,220 observations of ARV drugs acquired between 2016 and 2019. Results indicate that random forests exhibited the highest precision in predicting price changes, followed by KNN and logistic regression. Significant factors affecting acquisition prices, such as drug type and duration of procurement strategy, were identified. In addition to analyzing price trends, the paper explores the budgetary considerations associated with these fluctuations, providing insights into the financial implications for healthcare systems and stakeholders. It is important to note that this paper focuses on a specific ARV pharmaceutical purchasing scheme. Moreover, the study emphasizes the creation of a unified and detailed medication price database, highlighting the significant effort invested in compiling complete and comprehensive information from various sources. This study’s findings underscore the effectiveness of initiatives such as consolidated purchasing approaches and the integration of newer, cost-effective medications into treatment protocols. These initiatives have led to significant cost savings in antiretroviral medication procurement, contributing to improved access for individuals living with HIV/AIDS. Overall, the research highlights the importance of data-driven approaches and strategic planning in optimizing pharmaceutical purchasing processes and ensuring sustainable access to essential medications for public health interventions.

Resumen Este trabajo examina las tendencias en los precios de medicamentos antirretrovirales y su impac to en la salud pública, centrándose en el contexto mexicano en 2019. Por medio de técnicas de aprendizaje automático, el estudio analiza las fluctuaciones en los precios de los medicamentos antirretrovirales, con base en un conjunto de datos que comprende 15,220 observaciones de medicamentos antirretrovirales (ARV) adquiridos entre 2016 y 2019, con énfasis particular en el año 2019. Los resultados indican que los “bosques aleatorios” demostraron la mayor precisión en la predicción de cambios de precios, seguidos por K-Nearest Neighbors o KNN (algoritmo de k vecinos más próximos) y la regresión logística. Se identificaron factores significativos que afectan los precios de adquisición, como el tipo de medicamento y la duración de la estrategia de adqui sición. Además, el estudio profundiza en las consideraciones presupuestarias, evaluando las im plicaciones financieras de estas fluctuaciones de precios. Estos hallazgos destacan la efectividad de iniciativas como los enfoques de adquisición consolidada y la integración de medicamentos más nuevos y rentables en los protocolos de tratamiento, lo que conduce a ahorros significativos y mejor acceso para las personas que viven con VIH/sida. Es importante destacar que este artículo se centra en analizar un esquema específico de adquisición de medicamentos antirretrovirales. Los estudios futuros ampliarán este análisis para abarcar un espectro más amplio de esquemas de adquisición de medicamentos, proporcionando así una comprensión más completa de la di námica de fijación de precios y sus implicaciones para la salud pública. Además, la investigación en curso perfeccionará la metodología e integrará fuentes de datos adicionales para mejorar la precisión y profundidad del análisis.

HIV/AIDS remains one of the world's most significant public health and economic challenges, with approximately 36 million people currently living with the disease. Considerable progress has been made to reduce the impact of HIV/AIDS in the past years through successful multiple HIV/AIDS prevention and treatment interventions. However, barriers such as lack of engagement, limited availability of early HIV-infection detection tools, high rates of HIV/sexually transmitted infections (STIs), barriers to access antiretroviral therapy, lack of innovative resource optimisation and distribution strategies, and poor prevention services for vulnerable populations still exist and substantially affect the attainment of the UNAIDS 95-95-95 targets. A rapid review was conducted from 24 October 2022 to 5 November 2022. Literature searches were conducted in different prominent and reputable electronic database repositories including PubMed, Google Scholar, Science Direct, Scopus, Web of Science, IEEE Xplore, and Springer. The study used various search keywords to search for relevant publications. From a list of collected publications, researchers used inclusion and exclusion criteria to screen and select relevant papers for inclusion in this review. This study unpacks emerging opportunities that can be explored by applying machine learning techniques to further knowledge and understanding about HIV service design, prediction, implementation, and evaluation. Therefore, there is a need to explore innovative and more effective analytic strategies including machine learning approaches to understand and improve HIV service design, planning, implementation, and evaluation to strengthen HIV/AIDS prevention, treatment, and awareness strategies.

Resumen: En esta investigación se analizó un conjunto de mensajes de recaudación para el pago de impuestos. En total, se evaluaron doce variaciones de los mensajes de cobro (normas sociales, simplificación, divulgación, compromiso previo, recordatorios y decisiones pasadas) y se determinó su efectividad. Los mensajes fueron transmitidos a microempresarios morosos en cuatro estados brasileños. A partir de una base de datos que contiene información sobre microempresarios morosos, se enviaron 250 000 mensajes de texto para hacer el cobro. Los datos se obtuvieron de la Secretaria Especial da Micro e Pequea Empresa (Sempe). Se utilizaron pruebas para analizar la diferencia entre medias y se utilizó una secuencia de regresión logística. Se utilizaron los widgets Random Forest, regresión logística y Naïve Bayes para definir la solidez del modelo predictivo de Machine Learning. Los resultados de la investigación indicaron que los formatos “simplificación”, “decisiones pasadas” y “alerta” no tuvieron ningún efecto en la lucha contra el incumplimiento. Sin embargo, al combinarlos con mensajes que aludan a normas sociales, los mensajes con el estilo de “decisiones pasadas” y “recordatorios” aumentaron el pago de la deuda. Los widgets empleados mostraron un ajuste excelente al modelo de machine learning. La herramienta Random Forest determinó que el modelo es robusto y adecuado para la función predictiva. Los resultados de la encuesta brindan un aporte a las políticas públicas, pues presentan una acción efectiva para reducir la morosidad tributaria. El uso de mensajes que apelan a las normas sociales puede adaptarse a otras situaciones, y se sugiere aplicarlo en futuras investigaciones.

Abstract: In this research, a group of charging messages for the payment of taxes was investigated. Altogether 12 variations of billing messages (social norms, simplification, disclosure, previous engagement, reminders and previous choices) were evaluated, and their effectiveness was tested. The messages were transmitted to defaulting microentrepreneurs in four Brazilian states. From a database containing information about defaulting micro entrepreneurs, 250 thousand text messages were sent making charges. The data were obtained from the Secretaria Especial da Micro e Pequena Empresa (Sempe). Tests were used to analyse the difference between means and Logistic Regression was used in sequence. The Random Forest, Logistic Regression and Naïve Bayes widgets were used to indicate the robustness of the Machine Learning predictive model. The research findings indicated that the formats “simplification”, “previous choices” and “alert”, employees, did not have an effect in combating default. However, when aligned with social norms, messages in the form of “past options” and “reminders” increase the payment of debts. The widgets used indicated an excellent fit to the machine learning model. The Random Forest tool attested with superiority that the model is robust and suitable for the predictive function. The results of the research provide a contribution to public policies when they present an effective action to reduce defaults in the payment of taxes. The use of messages in the social norm format can be adapted to other situations, constituting a suggestion for future research.
