Published: September 2023

This study is intended to develop sequence and series materials based on the Personalized System of Instruction (PSI). The PSI is a private-based or modified individual with a cooperative learning system using a modular system where learners are assisted by a tutor, the system is the one that has a role as tutor here. The developed teaching material is a high school level e-module. The design used is the ADDIE model of the five stages of analysis, design, development, implementation, and evaluation. The analysis phase includes needs analysis and curriculum analysis. The design phase produces PSI-based e-modules. The development stage produces teaching materials that have been validated by experts and practitioners get very feasible criteria, based on aspects of content feasibility, linguistic aspects, data presentation aspects, and graphic aspects. The implementation stage was carried out by 70 students with above-average KKM. The evaluation stage shows that the results of the analysis of the e-module assessment questionnaire data by students get appropriate. That this teaching material in the form of an e-module is worthy of being an alternative teaching material at the high school level.
Defining and Promoting Pediatric Pulmonary Health: Equitable Family and Community Partnerships
Authors: Smith Brandon M. , Smith Tyler K. , Holve Steve , Connor Katherine A. , Coleman Cara , Tschudy Megan M.
Published: September 2023

Optimizing pulmonary health across the lifespan begins from the earliest stages of childhood and requires a partnership between the family, pulmonologist, and pediatrician to achieve equitable outcomes. The Community Pediatrics session of the Defining and Promoting Pediatric Pulmonary Health workshop weaved together 4 community-based pillars with 4 research principles to set an agenda for future pediatric pulmonary research in optimizing lung and sleep health for children and adolescents. To address diversity, equity, and inclusion, both research proposals and workforce must purposefully include a diverse set of participants that reflects the community served, in addition to embracing nontraditional, community-based sites of care and social determinants of health. To foster inclusive, exploratory, and innovative research, studies must be centered on community priorities, with findings applied to all members of the community, particularly those in historically marginalized and minoritized groups. Research teams should also foster meaningful partnerships with community primary care and family members from study conceptualization. To achieve these goals, implementation and dissemination science should be expanded in pediatric pulmonary research, along with the development of rapid mechanisms to disseminate best practices to community-based clinicians. To build cross-disciplinary collaboration and training, community–academic partnerships, family research partnerships, and integrated research networks are necessary. With research supported by community pillars built on authentic partnerships and guided by inclusive principles, pediatric lung and sleep health can be optimized for all children and adolescents across the full lifespan in the community in which they live and thrive.

Modern aspects of the pathogenesis of acute inflammation of the peritoneum that is concurrent with diabetes involves analysis of metabolic mechanisms, in particular peroxidaton of proteins – antioxidant defense. Therefore, the objective of our study was to examine the interrelation between the processes of free-radical oxidation of proteins and antioxidant system in the dynamics of development of acute generalized peritonitis against the background of streptozotocin-induced diabetes. The study was performed on 56 non-linear white mature male rats. Diabetes mellitus was modeled by a single intraperitoneal injection of streptozotocin (60 mg/kg). On the 14th day of the development of streptozotocin-induced diabetes, we injected 10% filtrated faeces suspension (0.5 mL) into the abdominal cavity, thus initiating acute generalized peritonitis. Oxidative modification of proteins in blood serum was studied using the I. F. Meshchyshen’s method and the condition of antioxidant protection was monitored according to the activities of superoxide dismutase, catalase, content of reduced glutathione, and the level of ceruloplasmin. The study of the parameters of free-radical oxidation of proteins and study of the condition of antioxidant system in blood of the rats with experimental acute generalized peritonitis against the background of streptozotocin-induced diabetes demonstrated that oxidative protein modification grew, while the parameters of the activity of antioxidant system were being inhibited, depending on the stage of acute inflammation of the peritoneum. We determined inverse correlation relationships between the products of free-radical oxidation of proteins and parameters of antioxidant system on the third and on the seventh days of modelling of combined pathology. Manifestation of acute generalized peritonitis concurring with streptozotocin-induced diabetes was accompanied by a gradual accumulation of the products of free-radical oxidation of proteins and exhaustion of the antioxidant defense during all stages of the development of acute inflammation of the peritoneum, peaking on the seventh day after administration of faecal suspension (terminal stage of peritonitis). The observed inverse correlations between the levels of oxidative modification of proteins and the activity of superoxide dismutase, catalase, reduced glutathione, and ceruloplasmin on the third and on the seventh days of modelling of combined pathology indicate a predictive role of the processes of free-radical oxidation of proteins in exhaustion of antioxidant-defense resources.

Authors: Valenzuela Rettig Pilar , Conejeros Obreque Francisca
Published: September 2023

El presente artículo corresponde a estudio de caso sobre la problemática de las prácticas pedagógicas inclusivas desde una perspectiva mapuche y rural. Las niñas, niños y adolescentes de esta cultura se encuentran en desventaja educativa por no ser parte de la población normativa de la ciudadanía chilena. Sin embargo, identificamos instituciones educativas que generan prácticas inclusivas contextualizadas al territorio en busca de una mejor educación para la comunidad. Una de estas es la escuela rural de Puquiñe Bajo, en la comuna de Lanco, Región de los Ríos, Chile. El objetivo del estudio fue analizar estas prácticas en la escuela, con la finalidad de lograr la inclusión del estudiantado desde sus identidades mapuche y rural en el sistema escolar chileno. El enfoque fue cualitativo, descriptivo, con desarrollo de observación participante y entrevistas a docentes realizadas durante el año 2022. Los resultados evidenciaron el desarrollo consolidado y colaborativo de la comunidad escolar en cuanto a las prácticas: implementación de sellos interculturales en el Proyecto Educativo Institucional, relevancia de la historia del territorio, trabajo pedagógico en y con identidad mapuche, trabajo colaborativo con las familias, adecuaciones curriculares y Aprendizajes Basados en Proyectos e investigaciones culturales. Por tanto, se presentan datos importantes para ser considerados en los procesos de gestión pedagógica en comunidades que tengan los antecedentes de ruralidad y origen étnico. También, estos datos sirven para los equipos de investigación en educación intercultural e inclusiva, junto a docentes de formación inicial para promover una educación inclusiva.

Published: September 2023

En el contexto carcelario costarricense, el Centro de Formación Juvenil Zurquí (CFJZ) alberga jóvenes con edades entre los 12 y los 22 años que cuentan con un historial de abandono anticipado del sistema educativo o que no desarrollaron las habilidades propias para la lectoescritura. ¿Cómo es posible enseñar a leer a la población con sobreedad que ha abandonado las aulas y que se ha enfrentado a procesos de exclusión? ¿Cuál metodología responde a las necesidades de la población joven privada de libertad? Este artículo documenta el proceso llevado a cabo desde un estudio de caso con una joven de 17 años, Ana, madre de una niña, con un historial de analfabetismo por la no escolarización, conductas desafiantes, cuadros depresivos y la dificultad para aprender a leer y escribir bajo diversos modelos. La docente a cargo intenta desarrollar el proceso de escritura desde el enfoque social partiendo del nombre de su hija, Elena, como palabra generadora. La visión de Freire plantea que la palabra generadora es primeramente significativa cuando se propicia la participación de cada estudiante y se le involucra naturalmente. En dos semanas, Ana reconocía aproximadamente 20 palabras y las relaciones entre los fonemas para llegar a la formación de palabras y oraciones. La joven logra desarrollar frases de agrado y desagrado partiendo de los vínculos y las situaciones familiares a las que se enfrentó, lo cual fue un estímulo para su deseo de aprender. Esta experiencia investigativa, documentada durante los años 2020 al 2022, demuestra que es posible propiciar la alfabetización considerando la diversidad de aprendizajes y los retos propios de una educación en contextos carcelarios.

Authors: Aoki Takuto , Suzuki Tomomasa , Sunami Yuta , Zhang Hong , Okamura Yosuke
Published: September 2023

A combination of roll-to-roll coating and nanoimprinting technique is proposed for large-scale fabrication of porous nanosheets. Poly (d,l-lactic acid) (PLA) in 2-methoxy-1-methylethyl-acetate is roll-to-roll coated on polypropylene substrate to obtain nanosheets with thickness above ca. 95 nm. Roller nanoimprinting with a nickel mold is applied to fabricate pores on nanosheets with diameter of ca. 1.2 μm. The imprinted PLA nanosheets with thickness above ca. 129 nm can be directly peeled from the substrate using a polyester adhesive tape frame with open circle of 30 mm. This method shows promising potential for achieving continuous production of porous nanosheets to facilitate their application.

Análise estatística da influência dos parâmetros de processamento na planicidade de placas de zircônia estabilizada com 8%mol de ítrio obtidas por colagem de fita
Authors: Sigeiro Augusto Prata , Marcomini Raphael Fortes
Published: September 2023

RESUMO No presente estudo, lotes de placas de zircônia estabilizada com 8% mol de ítrio (TZ8Y) foram fabricados pela técnica de colagem de fita, variando entre eles a composição da suspensão, como o volume de sólidos e os teores de ligantes, de plastificante do tipo I e de plastificante do tipo II com o intuito de verificar a influência destes parâmetros e do comportamento tixotrópico da suspensão sobre o empenamento do produto final. Após sinterizadas, a topografia das placas foi mapeada por meio de um relógio comparador, tomando medidas sobre a superficia das placas em um sistema de coordenadas, e, a partir desse sistema, foi definido um índice numérico que quantifica a planicidade das amostras. A influência foi investigada através de uma análise estatística bivariada, relacionando o índice de planicidade com cada um dos parâmetros alvo. A análise apresentou uma correlação negativa forte e significativa pelo teste de Spearman (⍴ ≅ 0,95 e valor-p < 10–3) entre o teor de plastificante do tipo I e a planicidade das placas produzidas, porém para os outros parâmetros analisados a correlação não pôde ser considerada estatisticamente significativa. Além disso, os resultados mostraram também que a utilização de um pós processamento nas fitas à verde, como uma laminação, melhorou substancialmente a planicidade das placas após a sinterização.

Resumo Objectives: to determine the prevalence of pathological findings according to the type of chorionicity in pregnancies in two institutions in Bogotá, Colombia. Methods: descriptive, retrospective, cohort study. Biometric variables were calculated, and pathological findings were evaluated according to the type of chorionicity in multiple pregnancies. Statistical characterization was performed with absolute frequencies, calculation of relative frequencies in qualitative variables, standard deviation measures, median and interquartile range. In addition, a descriptive analysis of the information was carried out. Results: 528 studies were carried out in 141 pregnant women, 98.5% (n = 139) twins and 1.4% (n = 2) triplets. A prevalence of 35.4% of fetal complications was calculated. The most frequent was fetal growth restriction (p=0.37). According to each type of chorionicity, fetal growth restriction was presented in 50% (1/2) of the trichorionics, 16.6% (7/42) of the monochorionics, and 11.3% (11/97) of the dichorionics. Conclusion: fetal growth restriction was the most common finding, both in trichorionics, monochorionics and dichorionics pregnancies.
Deconstruir estereotipos y visibilizar la dominación gracias a la traducción literaria
Authors: Alarcón Soledad Díaz
Published: September 2023

Resumen: En la sociedad actual la mujer sigue soportando la infravaloración y el abuso por parte del colectivo masculino, quien, a través de técnicas de dominación y creación de estereotipos arbitrarios y artificiales, insiste en que esta situación de asimetría es connatural al ser humano. Consideramos que este desequilibrio se neutraliza con una educación para nuestros jóvenes basada en la igualdad y el respeto. En este trabajo analizamos los segmentos que vehiculan micromachismos y estereotipos en la novela Des poupées et des anges (2004) de Nora Hamdi, siguiendo las técnicas de dominación de Berit Ås (2004) y los parámetros de medición de estereotipos de Colás y Villaciervos (2009). La traducción al español de los ejemplos permite a nuestro alumnado universitario reflexionar sobre las agresiones que sufre la mujer, y cómo el lenguaje participa de actitudes excluyentes y de control individual y social.
El género como dispositivo de poder: un análisis a partir de tres órdenes patriarcales
Authors: Rodríguez Ugalde Diana Cecilia
Published: September 2023

Resumen: El ensayo sostiene como argumento central que las deudas históricas del patriarcado con las mujeres lo son con toda la humanidad, aunque con alcances distintos. Para ello, retoma los análisis que han realizado Federici, Mies y Segato sobre las reconfiguraciones del orden patriarcal frente a la conformación y las mutaciones del orden del capital. En específico, expone el entramado social de tres órdenes patriarcales: uno, en un relato etnográfico, que muestra al género como un elemento fundamental del crimen organizado en Michoacán, con base en lo observado con trabajadoras y trabajadores de educación básica. El segundo, en el surgimiento del capitalismo en Europa, y el tercero, durante la intromisión del mundo colonial-moderno al mundo-aldea en tiempos contemporáneos en América Latina. Posteriormente, analiza los alcances que tienen estos tres órdenes patriarcales en la vida de hombres y mujeres.
Taxas de administração de fundos: o papel da concorrência da indústria e do sentimento do investidor
Authors: Silva Sabrina Espinele da , Pereira Leticia Fernandes , Iquiapaza Robert Aldo
Published: September 2023

Resumo Este artigo analisa a influência da concorrência da indústria e do sentimento do investidor sobre a probabilidade de alteração nas taxas de administração dos fundos de investimento no Brasil. Devido à grande variedade de fundos existentes, com características e objetivos diversos, pode haver diferenças significativas nas taxas observadas. Assim, é importante analisar os fatores que influenciam os valores das taxas de administração dos fundos, já que a literatura destaca que a cobrança de taxas é relacionada ao desempenho dos fundos. Além disso, observa-se que a indústria de fundos brasileira, apesar de ter um grande número de fundos disponíveis, ainda se concentra em poucas administradoras, o que é um indicativo de que existe um baixo nível de concorrência. Em termos práticos, a investigação pode ser útil a investidores no processo de seleção dos fundos, uma vez que a taxa de administração representa um dos principais custos ao qual um investidor se depara ao investir nessa indústria. Os resultados apontam a importância da adoção de maior transparência na divulgação das taxas, por parte das instituições financeiras, uma vez que há indicações de que os valores cobrados são influenciados pelas características dos fundos e dos investidores. A metodologia adotada envolve modelos de regressão Logit/Probit, que tiveram as alterações da taxa de administração como variável explicada e, como variáveis explicativas, as proxies da concorrência e do sentimento do investidor, além de outras variáveis de controle. Observou-se que a proxy de sentimento do investidor foi significativa para explicar a probabilidade de alteração das taxas de administração, principalmente para fixação de taxas mais elevadas. Porém, não foi observada significância estatística para a concorrência da indústria. Esta pesquisa inova ao analisar o papel da concorrência da indústria e do sentimento do investidor sobre a probabilidade de alteração das taxas de administração, contribuindo para preencher um gap encontrado na literatura nacional.

Authors: Solar Horacio , Ortiz Andrés , Aravena María , Goizueta Manuel
Published: September 2023

Resumo Para desarrollar una visión competencial del aprendizaje, varias investigaciones han puesto el acento en las competencias de modelación y argumentación. Si bien existe una nutrida literatura en ambas competencias matemáticas, es muy escasa en la literatura el abordaje conjunto de la argumentación y modelación. Este estudio tiene como propósito caracterizar las relaciones entre la argumentación y la modelación en el aula de matemáticas. A partir de una experiencia de desarrollo profesional docente, se presentan el análisis de dos casos de profesoras quienes diseñaron una actividad de modelación y argumentación. Los resultados de este estudio indican que se plantean tres relaciones importantes entre la argumentación y la modelación: 1) Las tareas matemáticas diseñadas favorecieron el desarrollo de la modelación y argumentación en los estudiantes; 2) los modelos actúan de manera implícita como respaldo de las garantías y refutaciones dados por los estudiantes; 3) la argumentación en el aula favorece que los estudiantes transiten por las distintas fases del ciclo de modelación.
Conexiones matemáticas identificadas en una clase sobre las funciones exponencial y logarítmica
Authors: Campo-Meneses Karen Gisel , García-García Javier
Published: September 2023

Resumen Se analizaron las conexiones matemáticas que emergieron durante una clase de matemáticas, de cuarto semestre, de un bachillerato mexicano, en la que se abordó como objeto de estudio a las funciones exponencial y logarítmica. El análisis de datos se realizó empleando parte del análisis ontosemiótico, en el que se identificaron las conexiones matemáticas entre los objetos primarios que emergieron en las diferentes prácticas matemáticas realizadas. Las conexiones matemáticas se conciben como un proceso mediante el cual una persona establece una relación verdadera entre dos o más conceptos, definiciones, proposiciones, representaciones etc. Uno de los resultados encontrados es que la conexión de reversibilidad entre las funciones no fue establecida en la clase y que la conexión mayormente evidenciada fue la de representaciones diferentes (entre los registros lenguaje natural, simbólico y gráfico).
Los parámetros y las infinitas soluciones en sistemas de ecuaciones lineales
Authors: Hernández-Zavala Luis Enrique , Acuña-Soto Claudia , Liern Vicente
Published: September 2023

Resumen En el presente trabajo investigamos la utilidad didáctica de usar parámetros como variables de naturaleza dual (variables activas o inactivas), así como la actualización de cinco profesores mexicanos en este saber. En esta actualización se analizaron sistemas de ecuaciones lineales (SEL) con dos ecuaciones y tres incógnitas que tienen infinitas soluciones. Para ello propusimos, vía internet, cinco artefactos semióticos: 1. una definición, 2. la inclusión del parámetro en el SEL, 3. el cálculo de soluciones, 4. representaciones gráficas y 5. la aplicación a un problema en contexto. Los resultados revelaron la pertinencia de la introducción del parámetro mediante este proceso y, además, los profesores lograron un control sobre las soluciones válidas de entre las infinitas del sistema planteado. Para algunos profesores, la estrategia y el papel del parámetro fue sólo un método más que se agrega a los ya conocidos; sin embargo, para otros, permitió dar una explicación a la relación entre la variable y el parámetro, así como la posibilidad del uso controlado de las infinitas soluciones.

Authors: Santos Jéssica de Castro , Arreguy-Sena Cristina , Pinto Paulo Ferreira , Lopes Rafael Oliveira Pitta , Vilela Talyta do Carmo , Brandão Marcos Antônio Gomes
Published: September 2023

ABSTRACT Objective: To describe contents, structure and origin of social representations about falls by elderly people, the peridomiciliary structural conditions that predispose to falls, and to relate the implications of these empirical evidence on the routine of the elderly in the architectural context. Method: Convergent mixed method by triangulation. Qualitative approaches(structural, n=195 and procedural, n=40of the Theory of Social Representations) and quantitative (descriptive sectional, n=183) were used. Elderly people enrolled in primary care were interviewed at home in 2018. Analysis techniques: categorical-thematic, prototypical, statistical, and deductive according to Leininger. Results: Categories of analysis: 1) Peridomicile: fall scenario and 2) Aging and vulnerability: risk of falls in peridomicile. The following environmental characteristics were precursors to falls: uneven floors, holes, unevenness and objects in the pathway. Feelings and behaviors allocated in the possible central core are associated, justifying falls, and determining their causes. Conclusion: There was an association between the peridomiciliary architectural environment and the predictive characteristics of the risk of falls.

Occupation and cancer in Brazil: a perennial challenge
Authors: Fernandes Gisele Aparecida , Wünsch-Filho Victor
Published: September 2023

Abtract Introduction: cancer incidence is increasing worldwide, especially in low- and middle-income countries. Objective: to identify and synthesize knowledge about occupational exposure and cancer, with emphasis on Brazilian scientific publications. Method: essay based on reviews carried out in the SciELO and PubMed databases. Results: a recent study identified 47 occupational agents among the 120 classified as definitively carcinogenic to humans by the International Agency for Research on Cancer. Studies carried out in the last two decades suggested fractions of cancer attributable to occupation, ranging from 1.3% in Brazil to 8% in Finland, although the criteria for measuring exposure in these studies can be questioned. In Brazil, scientific production on occupation and cancer is limited. The Revista Brasileira de Saúde Ocupacional (RBSO) published, between January 2003 to July 2022, six articles on the subject. In the PubMed database, from 2012 to 2022, 14 studies carried out in Brazil were identified. Conclusion: expanding research in this subject in Brazil is imperative to obtain more accurate estimates of workers exposed to carcinogens and related malignant tumors, essential to support public health actions and to establish norms on exposure limits or agents banning, reducing the burden of cancer in the Brazilian society.

Abstract Introduction The COVID-19 disease caused a pandemic, generating an overload on health services, especially in hospital institutions, due to the need for hospitalization of infected patients. Among health professionals, the occupational therapists have contributed to coping with the disease. Objective To verify the performance of occupational therapists in hospital contexts in the first year of the COVID-19 pandemic. Method This is a cross-sectional, exploratory, descriptive study with a quantitative approach. The research was developed using Google Forms®, with data collection through a questionnaire with open and closed questions, with occupational therapists working in hospital care as participants. Data were described and statistically analyzed using Statistica 9.1 software and Fisher's exact test. Results 36 occupational therapists participated, of which 23 treated patients with COVID-19 (63.9%). Of the participants, 75% responded that they modified their intervention with the onset of the pandemic and 91.7% considered their role fundamental during this period. The percentage of therapists who consider their performance as an occupational therapist fundamental during the pandemic in the group that worked with patients with COVID-19 (p=0.040) is significantly higher compared to the group that did not work with patients with COVID-19 (76.9%). In caring for patients with COVID-19, most occupational therapists responded that their role was specific to the scope of their profession (86.9%) and important in combating the disease (60.8%). Conclusion The results bring enlightening data about the interventions of occupational therapists, leading to critical-reflective discussions about the need to appropriate a new practice in a hospital context.

Abstract Introduction This article proposes to understand the daily life of informal caregivers through their narratives from the perspective of Occupational Therapy under the implications in occupational areas. Objective Analyze from the occupation areas of self-care, productivity and leisure, the narratives of women who exercise the role of informal caregiver. Method Qualitative research, with a narrative approach to obtain the experience of the caregivers since they assumed this role, through a semi-structured interview that was carried out with five informal caregivers belonging to the Valdivia commune, Los Ríos Region (Chile). Results Repercussions were identified in the self-care area, expressed in overload, multiplicity of roles, mood and sleep disorders. In terms of productivity, these women manage to reconcile their daily lives with their work, the support of third parties being a protective factor. Finally, in leisure time, the space for themselves is drastically reduced by both the work and the health situation, making it impossible to balance their routines. Conclusions Exercising the role of caregiver implies a change in occupational areas, which directly and indirectly affects daily life, since there is an abrupt break in the routine, enhanced by the lack of social support and / or the normalization of the performance of this role by women. In addition, the confinement measures due to COVID-19 increased the impact of the role of caregiver in the daily life of these women, expressed in a greater workload and a significant decrease in self-care.

Abstract This study evaluated the efficacy of therapeutic baths with Carapa guianensis (andiroba) oil against monogeneans of Colossoma macropomum (tambaqui), as well as the hematological and histological effects on fish. Among the fatty acids identified in C. guianensis oil, oleic acid (53.4%) and palmitic acid (28.7%) were the major compounds, and four limonoids were also identified. Therapeutic baths of 1 hour were performed for five consecutive days, and there was no fish mortality in any of the treatments. Therapeutic baths using 500 mg/L of C. guianensis oil had an anthelmintic efficacy of 91.4% against monogeneans. There was increase of total plasma protein and glucose, number of erythrocytes, thrombocytes, leukocytes, lymphocytes and number of monocytes and decrease in mean corpuscular volume. Histological changes such as epithelium detachment, hyperplasia, lamellar fusion and aneurysm were found in the gills of tambaqui from all treatments, including controls with water of culture tank and water of culture tank plus iso-propyl alcohol. Therapeutic baths with 500 mg/L of C. guianensis oil showed high efficacy and caused few physiological changes capable of compromising fish gill function. Results indicate that C. guianensis oil has an anthelmintic potential for control and treatment of infections by monogeneans in tambaqui.

Abstract The aim of this study was to investigate the association between chronic Anaplasma marginale and Babesia spp. infection and hematological parameters of pregnant and non-pregnant taurine heifers. Blood samples from 94 females were collected on the first day (D-10) of timed artificial insemination (TAI) protocol and on pregnancy diagnosis (D+34). Hematological parameters were determined and compared between pregnant (PG) and non-pregnant (NPG) heifers, and within group at different sampling days. Real-time PCR (qPCR) was used to determine A. marginale and Babesia bovis infection, and for absolute quantification of Babesia spp. between PG and NPG groups. Correlation analysis was performed between the number of gDNA copies (CN) of Babesia spp. and hematological parameters. On D-10, mean hemoglobin concentration was higher for NPG, and hematocrit and total plasma protein were higher on D+34 for both groups. There was no difference in Babesia spp. CN between groups. In the first qPCR, all heifers were positive for A. marginale and B. bovis. Significant correlations were found between hemoglobin and erythrocyte and between hemoglobin and hematocrit (r = 0.8082 and r = 0.3009, respectively). Low levels of A. marginale and Babesia spp. did not affect hematological parameters of chronically infected pregnant and non-pregnant taurine heifers.
Análisis Causal de los Retrasos en la Aprobación de Materias de Primer Año en una Carrera de Ingeniería mediante Técnicas de Inferencia
Authors: Paz Hugo
Published: September 2023

En este estudio se exponen las técnicas de inferencia causal utilizadas para descubrir los factores subyacentes que contribuyen a los retrasos prolongados en la aprobación de cursos de primer año que se observan en la Carrera de Ingeniería Civil de la Facultad de Ciencias Exactas y Tecnología (FACET). de la Universidad Nacional de Tucumán (UNT), Argentina. Hasta el año 2019, los estudiantes tardan un promedio de 5 años en aprobar sus asignaturas del primer año. Determinar las causas de ese retraso fue el motivo de la presente investigación.
 
Nuestro análisis se basó en la utilización del marco de trabajo DoWhy (Blöbaum et al., 2022; Sharma y Kiciman, 2020) y Causal Discovery Toollbox (CDT) (Kalainathan et al., 2020), herramientas diseñadas para la inferencia causal. Nuestro objetivo era desentrañar la red de variables que influyen en los tiempos de aprobación de los cursos. Los hallazgos del estudio iluminan un factor causal fundamental que conduce a un aumento estadísticamente significativo en la duración de la aprobación. Específicamente, se reveló que la estructura regulatoria del programa académico y los métodos de evaluación empleados juegan un papel sustancial. En particular, la acumulación de materias regulares que aún no han sido aprobadas mediante un examen final surgió como un determinante clave.
Este conocimiento tiene el potencial de guiar intervenciones específicas, mejorando tanto las tasas de éxito de los estudiantes como la eficacia general del sistema educativo.
