The Suicidal Ideation Attributes Scale (SIDAS) and the Suicidal Behaviors Questionnaire-Revised (SBQ-R) are widely used psychological instruments for assessing people‘s suicidal ideation and suicidal behavior. The aim of this study was to examine the psychometric characteristics of the Lithuanian versions of the SIDAS and SBQ-R. We analysed data collected from four samples: a Lithuanian general population quota sample based on age, gender and place of residence (N = 697, 52.9% women, aged 18–79 years); a sample of students (N = 2013, 72 % women, aged 18–29 years); a clinical sample of suicidal patients (N = 35, 77.1% women, aged 18–59 years); and a test-retest sample of students who completed the instruments twice within a two-week period (N = 54, 70.4% women, aged 18–47 years). The participants answered questions on gender, and age and completed the SIDAS and SBQ-R. The data analysis revealed that the Lithuanian versions of the SIDAS and SBQ-R have good internal consistency, temporal stability, construct, convergent, and criterion validity. The Lithuanian versions of the SIDAS and SBQ-R can be used to measure suicidality in research settings, as well as in clinical work as auxiliary tools.

Authors: B Soni Hiren , M Multani Tahir
Published: July 2024

The specific epithet melanocephalus is derived from Greek words meaning "black" (melas) and "head" (kephalē), referring to the distinctive black plumage on the head and neck of the Black-headed Ibis. The Black-headed Ibis (Threskiornis melanocephalus) stands as a captivating symbol of avian grace amidst wetland habitats across Asia. With its distinctive black head contrasting against a white body, this elegant bird captivates both ornithologists and birdwatchers alike. In this review, we delve into the ecology, behavior, and conservation status of the Black-headed Ibis, shedding light on its significance in the avian world. It is a striking bird species belonging to the ibis family, Threskiornithidae. Known for its distinctive appearance and graceful appearance, this bird captivates observers across its range in South Asia, Southeast Asia, and parts of the Middle East. Threskiornis melanocephalus is commonly found in South Asia, Southeast Asia, and parts of the Middle East, where it inhabits freshwater marshes, flooded grasslands, and shallow lakes. While not globally threatened, this species faces localized threats such as habitat loss, pollution, and hunting, highlighting the importance of conservation efforts to safeguard its populations and their wetland habitats.1

The limits of the average value of the average annual external radiation dose rate of fishes from four lakes (with different degrees of radionuclide pollution of ichthyofauna representatives) of the Chornobyl Exclusion Zone as of 2021 are given, namely: Azbuchyn Lake (4 - 33 μGy/h), Vershyna Lake (3 - 26 μGy/h), Glyboke Lake (2 - 15 μGy/h) and Plyutovyshche Lake (0.02 - 0.16 μGy/h). Bottom-dwelling fish species such as tench and Prussian carp receive the highest external radiation dose, and rudd and surface fish species receive the lowest. It has been proven that the radionuclide 137Cs forms from 62.8 to 98.7 % of the absorbed dose of external irradiation of fishes from the studied water bodies. It is clearly shown that the current levels of the average annual absorbed external dose rate for many of the studied fishes of the lakes exceed the screening dose of 2 μGy/h and in 6 cases out of 22 exceed the safe level of 10 μGy/h recommended by the European Commission project “PROTECT”.
Dose estimates of 137Cs in bank voles inhabiting research sites within the Chornobyl Exclusion Zone considering the age-related dynamics of change in physiological parameters

Published: July 2024

Methods for dose estimation of 137Cs in mouse-like rodents, specifically bank voles (Myodes glareolus), commonly found within the research sites in the Chornobyl Exclusion Zone, are being proposed. The International Commission on Radiological Protection recommends using the specially developed "BiotaDC" software, but it needs to be adapted to solve specific applied issues. It is shown that the "BiotaDC" approach adequately describes dose accumulation of 137Cs for external exposure inside nest chambers if the mean integral value of soil activity concentration at a depth of 0.5 m is used, for external exposure above soil – if the mean integral value of soil activity concentration at a depth of 0.2 m is used. However, the authors propose a method considering the age of animals at the time of capture and the age-related dynamics of changes in such parameters as excretion and accumulation of radioisotopes for internal dose estimation using the "BiotaDC" software. A detailed dose estimation algorithm is being proposed. Dose estimates for internal irradiation according to the authors' method and the method of the International Commission on Radiological Protection are being compared.
Epidemiology of Acute Respiratory Failure in US Children: Outcomes and Resource Use
Authors: Odetola Folafoluwa O. , Gebremariam Achamyeleh
Published: July 2024

OBJECTIVE

Acute respiratory failure recalcitrant to conventional management often requires specialized organ-supportive technologies to optimize outcomes. Variation in the availability of these technologies prompted testing of the hypothesis that outcomes and resource use will vary by not only patient characteristics but also hospital characteristics and receipt of organ-supportive technology.

METHODS

Retrospective study of children 0 to 20 years old hospitalized for acute respiratory failure using the 2019 Kids’ Inpatient Database. Multivariable regression models identified factors associated with mortality, length of hospitalization, and costs.

RESULTS

Of an estimated 75 365 hospitalizations nationally, 97% were to urban teaching hospitals, 57% were of children < 6 years, and 58% were of males. Complex chronic conditions (CCC) existed in 62%, multiorgan dysfunction in 35%, and extreme illness severity in 54%. Mortality was 7%, length of stay 15 days, and hospital costs $77 168. Elevated mortality was associated with cumulative organ dysfunction (odds ratio [OR]:2.31, 95% confidence interval [CI]: 2.22–2.42), CCC (OR: 5.49, 95% CI: 4.73–6.37), transfer, higher illness severity, and cardiopulmonary resuscitation. Lower mortality was associated with extracorporeal membrane oxygenation (OR: 0.36, 95% CI: 0.28–0.47) and new tracheostomy (OR: 0.30, 95% CI: 0.25–0.35). Longer hospitalization was associated with transfer, infancy, CCC, higher illness severity, cumulative organ dysfunction, and urban hospitals. Higher costs accrued with noninfants, cumulative organ dysfunction, private insurance, and urban teaching hospitals.

CONCLUSIONS

Hospitalizations for pediatric acute respiratory failure incurred substantial mortality and resource consumption. Efforts to reduce mortality and resource consumption should address interhospital transfer, access to organ-supportive technology, and drivers of higher severity-adjusted resource consumption at urban hospitals.

OBJECTIVES

This study assessed the state of pediatric medical device (PMD) development by comparing PMD clinical trials to pediatric trials evaluating drugs and biologics, from 1999 to 2022.

METHODS

The site www.clinicaltrials.gov was used to identify and quantify both PMD clinical trials and pediatric trials for drugs and biologics. Clinical specialty was also assessed. The institutions included were the 7 children’s hospitals primarily affiliated with the Food and Drug Administration (FDA) Pediatric Device Consortia (PDC) grant program between 2018 and 2023. For a national comparison, an additional search assessed PMD trials across all US medical institutions.

RESULTS

A total of 243 PMD clinical trials were identified at the FDA–PDC institutions on the basis of the year of initiation; the average number of PMD trials initiated per year per institution was 1.5 from 1999 to 2022. However, PMD trials significantly increased during the period 2014 to 2022 compared with 1999 to 2013 (P < .001); the rate of initiation of drug and biologic pediatric trials demonstrated no significant differences between these time periods. A national survey of all institutions initiating PMD trials, and drugs and biologics trials, identified 1885 PMD trials out of a total 12 943. A comparable trend was noted in the national survey with initiation of PMD trials increasing significantly from 2014 to 2022 (P < .001), compared with 1999 to 2013, whereas the rate of initiation of drug and biologic trials during these periods did not demonstrate a significant change.

CONCLUSIONS

Although pediatric clinical trial initiation for drugs and biologics remained stable from 1999 to 2022, the rate of new PMD trials significantly increased during the period 2014 to 2022 at FDA–PDC institutions and nationally.

Quantifying Morphostructural Evolution of the Eastern Algerian Saharan Atlas (NE, Algeria) Using GIS-based Surface Envelope Technique, Drainage Network Analysis, and Geological Features
Authors: Boufaa Kamel , Bougherara Ahmed , Bouaicha Foued , Bouzenoune Azzedine
Published: July 2024

This research work focuses on the morphostructural evolution of the eastern end of the Algerian Saharan atlas. The study employs a comprehensive methodology involving the utilization of the surface envelope technique, combined with an analysis of the hydrographic network and geological context. These techniques are integrated within a GIS framework to decipher the current relief characteristics. To interpret the current relief features, two ASTGTM v2 tiles were processed to extract morphometric data. The reconstruction of the original relief requires the generation of the summit level surface, the base level surface and the relief amount maps for 3 different grid sizes (4000m, 1000m and 250m). The respective different grid size maps has allowed determining the initial surface of the reliefs; first before any major vertical erosion, then after a phase of dismantling and finally the recent and sub current morphological aspect.  The extraction of the hydrographic network and the elimination of lower than order 5 streams revealed the harmony of the latter with a raised shaped form (mega-horst) which represents the main morphostructural unit. This morphostructure is particularly characterized by outcrops from the Lower Cretaceous outcrops. The ramification of the hydrographic network along the main tectonic accidents has allowed the digging of wide valleys, often described as graben.
New insights into the Permian-Triassic magmatism of southern Cerro Cacheuta, Argentina
Authors: Martínez Amancay , Gallardo Adrian , Mulé Melisa , Giaccardi Aldo , Crespo Esteban , Aguilera David
Published: July 2024

The igneous rocks of Cerro Cacheuta are considered a typical expression of the Permian-Triassic magmatism within the Andes Precordillera of Mendoza, Argentina. In particular, the southwestern margin of this hilltop is characterised by intermediate volcanic and felsic intrusives from the Choiyoi Group, one of the most extensive volcano-sedimentary suites of southern South America. The Choiyoi magmatism is widely associated with dramatic tectonic and environmental changes in the Gondwana supercontinent. Therefore, a better characterisation of the igneous facies of Cerro Cacheuta is critical to understand the evolution of Gondwana and recognise the multiple events that occurred towards the end of the Permian. This paper presents new data about the mineralogy, petrography, and geochemistry of the plutonic and volcanic units of Cerro Cacheuta, which enables authors to draw additional conclusions about the genesis and evolution of the magmatism in the region. Microscope observations indicate that the volcanic rocks are largely consistent with intermediate facies dominated by a porphyry texture with plagioclase and sanidine phenocrystals within a trachytic groundmass. Coetaneous breccias of possible hydrothermal origin and geodes with cryptocrystalline silica, limonite, and quartz are also recognised in outcrops. Geochemical analysis suggests that the lavas would likely correspond to andesites from a calc-alkaline magmatic arc. Furthermore, trace elements show enrichment in LREE/HREE, a slight negative anomaly in Eu, and concentration ratios compatible with crustal extension during the initial stages of the Choiyoi Group. Based on their chemical similarities, the monzonites of the Boca del Río Pluton would correlate with the lower section of the Choiyoi Group, of Permian age. In contrast, granites of the Cacheuta Pluton show a signature typically recognised in units from the Triassic and, therefore, would be comparable to the upper member of the Choiyoi Group.

Apuntes sobre los análisis de la movilización popular de los setenta en El Salvador: una propuesta de nuevos conceptos para un viejo debate
Authors: Molinari Lucrecia
Published: July 2024

Entre 1980 y 1992 se desarrolló en El Salvador una guerra civil que enfrentó a sus fuerzas armadas y al Frente Farabundo Martí de Liberación Nacional (FMLN). Fue precedida por una movilización popular de enorme riqueza y carácter inédito (1972-1979). El presente trabajo revisa diversos análisis sobre la movilización desarrollada en la década de los 70, principalmente en el ámbito urbano, para dar cuenta de dos supuestos que subyacen en el debate: los 70 como antesala de la  guerra civil o la continuidad entre la movilización de los 70 y el desarrollo de la lucha armada, y la continuidad entre la movilización previa a la guerra civil y la transición democrática. Se plantea una lectura de la historia reciente salvadoreña que busca dialogar con las anteriormente mencionadas discutiendo esta idea de continuidad. Se enfatiza para ello en aquellas lógicas, dinámicas y elementos que se debilitaron o desaparecieron como resultado del salto represivo que tuvo lugar alrededor del año 1980.

Authors: Rojas Barrantes Erika , Picado Rossi Milena , Prado-Calderón Jorge Esteban
Published: July 2024

A en los cursos de Actuación V y VI de la Escuela de Artes Dramáticas de la Universidad de Costa Rica, se propone revisar críticamente algunos roles docentes tradicionales de la pedagogía de la actuación teatral. Por medio de una lectura crítica de estos roles se exponen sus elementos constitutivos y funciones, con el objetivo de desestabilizar las intencionalidades que los sostienen y valorar sus sentidos. Se concluye que las dinámicas implícitas en el ejercicio de la docencia colaborativa pueden considerarse para proponer nuevos roles docentes más coincidentes con nuestras miradas. Uno de estos roles es el que denominamos docente-comodín, inspirado en el Comodín de Augusto Boal y del Teatro de las Personas Oprimidas. Asimismo, se comparten otros hallazgos derivados de la experiencia que des-sedimentan la relación docente-discente y revelan aprendizajes significativos para las personas participantes.

Published: July 2024

Language teaching and error analysis are integral in Arabic language education, particularly evident among fifth-grade students at SD Tunas Harapan Ar-Raudhah, who face challenges in mastering Arabic pronunciation. These errors occur due to differences between the Indonesian and Arabic sound systems, which cause difficulties. This study included a total of 9 students as its sample group and focuses on analyzing pronunciation errors made by fifth-grade students of SD Tunas Harapan Ar-Raudhah to find out what letters often have errors in pronunciation and find out the factors that cause these errors, as well as finding and providing specific treatments to overcome and reduce the percentage of student errors. The method used in this research is descriptive qualitative with simak catat technique. The results showed 116 errors in Arabic consonant pronunciation (75.8%) during the pre-test, with the highest errors in three letters: dza, qaf, and 'ain. During the post-test, there were 37 errors (24.2%); this shows that the percentage of student errors decreased. The findings underscore the importance of tailored interventions in addressing pronunciation difficulties and contribute to refining language teaching strategies. Future research should explore alternative methodologies and replicate the study with larger student cohorts to enhance generalizability across diverse educational settings, further advancing effective Arabic language instruction

Authors: Fahri Muhamad , Arrahman Fajar Pinastia , Albantani Azkia Muharom , Mahfuzo Muhammad Rizal , Muslimin Muhamad Ihwanul
Published: July 2024

The main goal of learning Arabic is to develop practical linguistic skills among learners centered around the concept of willingness to communicate (WTC). WTC refers to learners' strong desire and readiness to speak in specific contexts or situations. A critical challenge is how to accurately measure WTC in Arabic language learning using a valid and reliable instrument. Understanding WTC is crucial as it indicates learners' motivation to use Arabic, enhances their speaking proficiency, and creates a supportive linguistic environment. Research on WTC in Arabic language learning is currently limited, necessitating further exploration in this area. Consequently, this study aims to develop a valid and reliable WTC measurement instrument for Arabic language learners using a quantitative approach, incorporating both Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) methods. The participants for this research are 204 Arabic language learners, and a survey was utilized for data collection. The WTC instrument employed in this study is an adaptation of existing instruments, modified to align with the context of Arabic language learning and the specific conditions of Indonesian learners. The findings reveal that the WTC construct has yielded valid and reliable items that can be used to measure WTC among learners in Arabic language learning. Furthermore, there are three main dimensions within this construct, namely, the context of online, classroom, and offline. Thus, it is hoped that the WTC construct developed can be utilized to measure aspects of WTC among Arabic language learners, thereby enabling the determination of further steps in realizing linguistic behaviors

Authors: Pleskach V. , Akimov I. , Kyrylakha S.
Published: July 2024

Purpose. The development of a method of thermal calculation of molds for the manufacture of products from composite materials, which allows you to choose an insulating material that ensures effective savings in heat consumption.
Research methods. A theoretical analysis of the existing thermal calculations of the molds was carried out; an analysis of the theory of heat exchange based on the theory of similarity was carried out, using dimensionless criteria of Nusselt, Grashof and Prandtl; an analysis of reference data on the properties of insulating materials was carried out.
Results. In the course of the work, the processes of convective heat transfer from the side surface of the mold were clarified and described; a method of calculating energy losses through heat transfer at a certain temperature on the outer surface of an uninsulated mold was developed; it was established that the temperature of the wall, from which the heat transfer is actually carried out, plays a decisive role in the selection of the insulating material; a method of reducing energy consumption is determined by applying a layer of heat-insulating material on the heat transfer surface of the mold, reaching a given temperature on the isolated surface of the mold; on the example of a mold of specific dimensions, the optimal materials were selected and their effectiveness in reducing heat consumption was determined.
Scientific novelty. Developed methods for evaluating the effectiveness of heat-insulating material by calculating the temperature on the insulated surface of the mold; in this connection, the reduction of heat loss through heat transfer is achieved with the help of the selected optimal heat-insulating material, which has the appropriate thermophysical and technological properties.
Practical value. Information on the impact of the design of the mold matrix and reference information on the thermal conductivity of heat-insulating materials are provided; the proposed calculation method can be used in the design of energy-saving molds for the manufacture of products from composite materials.

Published: July 2024

This study evaluates the efficacy of five machine learning algorithms Support Vector Regression (SVR), Decision Tree (DT), Random Forest (RF), Light Gradient Boosting Machine Regressor (LGBM), and Linear Regression (LR) in predicting water levels in the Vietnamese Mekong Delta's tidal river system, a complex nonlinear hydrological phenomenon. Using daily maximum, minimum, and mean water level data from the Cao Lanh gauging station on the Tien River (2000-2020), models were developed to forecast water levels one, three, five, and seven days in advance. Performance was assessed using Nash-Sutcliffe Efficiency, coefficient of determination, Root Mean Square Error, and Mean Absolute Error. Results indicate that all models performed well, with SVR consistently outperforming others, followed by RF, DT, and LGBM. The study demonstrates the viability of machine learning in water level prediction using solely historical water level data, potentially enhancing flood warning systems, water resource management, and agricultural planning. These findings contribute to the growing knowledge of machine learning applications in hydrology and can inform sustainable water resource management strategies in delta regions.

Published: July 2024

Cases of relatively safe dental implant treatment in patients with low-volume bisphosphonate (BP) have been gradually reported. Although bone augmentation is commonly used when the bone volume is insufficient for implant placement, the studies and case reports regarding the safety of bone augmentation in patients treated with BP remain insufficient. Herein, we report a case wherein bone augmentation was performed after BP treatment with bone healing realized according to imaging, and we review the literature regarding BP and bone augmentation. A 67-year-old Japanese woman requested implant treatment for a hopeless lower right second molar. She had been taking minodronic acid hydrate (50 mg/4 wk) for 18 months to treat steroid-induced osteoporosis. After obtaining informed consent, tooth extraction and bone augmentation within the extraction socket were performed. The tooth was extracted atraumatically to preserve the surrounding alveolar bone, and the extraction socket was intensely curetted. Subsequently, the socket was filled with carbonate apatite granules and covered with a biodegradable membrane, and the wound was sutured without tension. Although protracted wound healing without any symptoms of infection was observed, the wound healed completely. No clinical symptoms were observed, the color of the mucosa at the site was healthy, and imaging findings at 6 months postoperation indicated that osteogenesis had progressed uneventfully.

Informal employment, which is labor activity without official registration and corresponding tax and social contributions, causes serious challenges to economic stability, social justice, and sustainable development, affecting social protection systems, budgetary resources, and equality in the labor market. The purpose of the study is to improve the understanding of aspects of countering informal employment and to investigate the factors affecting informal employment. Methods of the study are comparative analysis, multiple regression analysis, differentiated difference method, logical method, induction and deduction, systematization, and graphical method. The information base of the study consists of data from the World Bank and the International Labour Organization (ILO). It is established that international cooperation in countering informal employment, taking the example of EU countries, has not yielded significant results in achieving its goals. We have determined that the level of GDP per capita, as well as the indicator of the share of people employed in the service sector, are negatively correlated with the level of informal employment. In addition, we found that in countries with a more active community of online freelancers, the level of informal employment is generally lower. The results of the study contribute to the understanding of the mechanisms of combating informal employment and can also serve as a source of information for the development and implementation of policies aimed at countering this phenomenon. The work can also be the basis for further research on the relationship of informal employment with indicators such as unemployment, the proportion of people employed in online freelancing, and other indicators.
Exploring Design Principles for STEAM Learning Activities Development by Science and Technology Teachers
Authors: Tsakeni Maria
Published: July 2024

This study explored the design principles of science, technology, engineering, arts, and mathematics (STEAM) learning activities developed by science and technology teachers for classroom practice. Through a qualitative approach, interpretive paradigm, and design-based research, 12 Bachelor of Education honours degree students were conveniently sampled. Data were collected by means of reflections and development of learning materials through the analysis, design, development, implementation, and evaluation (ADDIE) model. The study followed the design-based research stages of needs analysis, development, testing, and reflection to produce design principles, and it was underpinned by the learning theory of constructionism. The findings showcase the design principles to include design thinking, finding solutions for learning problems, creativity, and innovation applied to instructional design. The study recommends the use of design thinking pedagogies in developing teacher knowledge on STEAM classroom practice.

Authors: Cárdenas-Ibarra Álvaro , Hernández-Arévalo Jessica Lorena
Published: July 2024

Este artículo de investigación, enmarcado en la línea temática de “Pedagogía de la literatura”, presenta los resultados obtenidos tras el desarrollo de la investigación titulada “Lectura Literaria de Textos Verbo-Visuales: Una Ventana a la Experiencia Estética”, experiencia llevaba a cabo en dos colegios privados de Bogotá, en el marco de la Maestría en Pedagogía de la Lengua Materna. Esta investigación buscó desarrollar una propuesta de lectura literaria de textos verbo-visuales con el fin de generar espacios en el aula para la experiencia estética de los estudiantes. Para ello, se aplicaron una serie de talleres pedagógico-literarios que responden al paradigma interpretativo de enfoque cualitativo. En los hallazgos, se estableció que los textos verbo-visuales, al ser un tipo de discurso poco novedoso en la enseñanza de la literatura, dinamiza los procesos de lectura y creación de textos con intención literaria. Además, evidencia la necesidad de ampliar la experiencia en el canon literario y así propiciar el abordaje de nuevas formas de alfabetización.

Authors: Sierra-Piedrahita Ana María
Published: July 2024

This reflection article makes a call to the language teacher education field in Colombia to integrate social justice language education and critical language education perspectives to advance a social justice agenda in language teacher education. Its overall intention is to invite critical language teacher educators to expand the scope of their work by being knowledgeable about the theories or dimensions of social justice - redistribution, recognition and representation - and including social justice frameworks and principles in their practices. These elements are fundamental to tailoring teacher education programs and guiding pedagogical practices that prepare future teachers for social action and transformation.

Authors: Ramos-Pérez Juan Carlos , Gamboa-Mora María Cristina
Published: July 2024

Se presenta una revisión documental sobre la enseñanza y el aprendizaje del conflicto armado en Colombia, privilegiando aquellas investigaciones que aportan evidencias sobre el conocimiento didáctico en este campo de estudio. El balance bibliográfico se organiza teniendo en cuenta a quienes han sido sujetos de las investigaciones. Es así como, luego de una introducción donde se plantean algunas perspectivas investigativas sobre este asunto, se propone abordar metodológicamente el problema desde tres tradiciones de investigación. La primera se refiere al alumnado, sus representaciones y conocimientos sobre la guerra, y los resultados de sus aprendizajes. La segunda se detiene en el profesorado, sus enfoques de enseñanza de esta problemática y su formación inicial. La tercera estudia la dimensión curricular, centrándose en la política oficial y los contenidos y materiales utilizados para la enseñanza del conflicto armado colombiano. La revisión termina señalando algunas certezas y las principales ausencias en relación con el conocimiento didáctico en conexión con la guerra reciente en Colombia como problemática de enseñanza escolar.
Estado del conocimiento científico sobre la danza en educación física
Authors: Cuervo-Zapata Juan José , González-Palacio Enoc Valentín
Published: July 2024

La presente investigación tuvo como objetivo principal analizar el estado de conocimiento científico de la danza en el campo de la educación física escolar entre los años 2015 y 2022. El abordaje metodológico se ancló desde un enfoque cualitativo retomando las tres fases para la realización de un estado del arte propuestas por Gómez Vargas et al. (2015), de igual forma, se hizo una búsqueda de artículos de investigación en bases de datos científicas como Dialnet, Scielo, Web of Science, Ebsco y Scopus obteniendo un total de 697 registros, de los cuales se seleccionaron 68 artículos para el análisis, empleando una matriz de resumen analítico de investigación (RAI), diseñado por González Palacio (2019); se digitalizó la información en una base de datos en Microsoft Excel 2021 para la realización del análisis descriptivo (aspectos cuantitativos) y se hizo un mapeo a partir de herramientas de construcción de redes bibliométricas-semánticas, como es vosviewer (Ding et al., 2014) y Atlas ti versión 9. En conclusión, la danza, vista como un proyecto motor, permite considerar en el proceso una intencionalidad pedagógica a nivel corporal. Esto quiere decir que se analizan los pasos de movimientos a la vez que se busca que estas acciones doten de sentido los niveles cognitivo y expresivo de la persona que está inmersa en el acto, puesto que la danza facilita que el sujeto esté en contacto con un espacio y con otros cuerpos.

Published: July 2024

El propósito de este estudio es analizar a través de un diseño comparativo las variables asociadas a los cambios en el modelo de profesión académica en las instituciones normalistas de México. Es una investigación con enfoque cuantitativo, transeccional y de alcance causal-comparativo, realizado con una muestra de 312 académicos normalistas de tiempo completo. La recolección de información se llevó a cabo mediante la técnica de encuesta, con la aplicación de un cuestionario en una plataforma en línea. El cuestionario fue diseñado con base a las características y condiciones de la profesión académica normalista. Se realizó un análisis de las dimensiones de trayectoria académica, dedicación en horas a las funciones académicas, identidad académica, valoración de la investigación, valoración de la docencia y disposición al cambio. Los resultados advierten que la identificación de los participantes con rasgos específicos que definían la identidad académica del formador de formadores se encuentra en proceso de reconfiguración de determinadas dimensiones vinculadas con las trayectorias académicas, la dedicación y percepción de valoración de las actividades de investigación. El diseño metodológico permite inferir que los cambios que se están presentando en la profesión académica normalista se encuentran directamente relacionados con la obtención del reconocimiento de los programas de estímulo. Finalmente, se reflexiona sobre la homologación que genera la orientación de las políticas y la Ley General de Educación Superior sobre el subsistema de Escuelas Normales y los efectos que esto tiene sobre el modelo de profesión académica.
Mujeres que estudian en Escuelas Normales, profesionales, comerciales y liceos (Buenos Aires, 1880-1940)
Authors: Rodríguez Laura Graciela
Published: July 2024

En este artículo de investigación analizaremos el proceso de creación de escuelas para mujeres (Normal N. º 1, Comercial N. º 1, Profesional N.º 1 y Liceo N.º 1) ubicadas en la ciudad de Buenos Aires, en base a los informes que debían elevar anualmente las directoras a las autoridades, entre 1880 y 1940. Nos interesa aquí poner el foco en las características de cada escuela, de las trayectorias de las directoras y de las alumnas. Mostraremos que estas distintas creaciones de establecimientos de enseñanza secundaria, normal y especial no fueron neutrales en términos de género, dado que los funcionarios evitaron ofrecer las mismas oportunidades educativas a varones y mujeres, en el entendido que ambos estaban “naturalmente” mejor preparados para cursar en una u otra escuela.
