Authors: Longoria-Espinoza Rosa María , Félix-Gastélum Rubén , Zamudio-Aguilasocho Gloria Margarita
Published: January 2025

En el estado de Sinaloa, México, la producción de maíz blanco se realiza bajo un modelo de agricultura intensiva, lo que implica un uso indiscriminado de agroquímicos, técnicas de labranza inadecuada que deterioran la calidad de los suelos, contaminación de mantos freáticos y actualmente escasez de agua. Sin embargo, paulatinamente se van cambiando estos sistemas de producción por una agricultura de conservación como alternativa sustentable. El objetivo de este estudio es caracterizar molecularmente bacterias endófitas aisladas de plantas de maíz blanco (Zea mays L.) y evaluar in vitro la capacidad promotora de crecimiento vegetal y actividad antagónica contra hongos fitopatógenos. Se recolectaron plantas de maíz blanco híbrido PIONEER 4032 DEKALB, variedad sembrada durante el ciclo otoño-invierno 2022-2023; se aislaron bacterias endófitas de tejido (foliar, tallo y raíz); la diversidad de colonización presentó variaciones significativas en el tejido de la planta. Los aislados se caracterizaron a través de la amplificación y secuenciación del producto de la reacción en cadena de la polimerasa (PCR) del gen 16S rADN; se muestra la asociación al phyla Firmicutes del género Bacillus sp., los aislados endófitos de raíz como: Bacillus subtilis; B. amyloliquefaciens y B. cereus. La evaluación metabólica muestra a B. subtilis con capacidades relevantes de la promoción de crecimiento vegetal con alta producción de hormonas y solubilización de fosfatos. En el análisis in vitro de antagonismo, la cepa B. subtilis presentó el valor máximo de inhibición del hongo Sclerotium rolfsii, (87.09%). El género Bacillus se utiliza en la comprensión de procesos metabólicos y antagónicos ante patógenos que atacan cultivos de importancia económica. Es importante mencionar que existen pocos reportes de especies de Bacillus en maíz blanco cultivado en el municipio de Guasave, Sinaloa, México. Por lo tanto, estos resultados establecen bases para el establecimiento de bioensayos in planta con las cepas de bacillus aisladas de maíz blanco en pro de un modelo de agricultura sustentable.

El tomate saladette es la hortaliza con mayor consumo en el mundo. Sin embargo, las prácticas de fertilización excesivas generan contaminación ambiental. Una ventaja de la utilización del método de nutrición balanceada para el cálculo de dosis de fertilización es que, permite precisar las cantidades de fertilizantes en función de las metas de rendimiento. Sin embargo, para su aplicación se requiere el suministro edáfico y la eficiencia de recuperación de fertilizante además del valor denominado requerimiento nutrimental, el cual considera la necesidad de nutrientes para la producción de biomasa aérea y subterránea de las plantas. El tomate saladette es un cultivo que se puede manejar de manera intensiva a un tallo y solo dos racimos florales, pero hacía falta el valor de requerimiento nutrimental con este manejo. Por ende el objetivo de este estudio fue generar dicho valor; para lograrlo se establecieron plantas de tomate, en condiciones de invernadero y fertirrigación; a los 70 días después de trasplante se extrajeron diez plantas y cuantificaron por órgano peso fresco y seco, producción de fruto comercial y fruto no comercial. Posteriormente se analizaron las concentraciones de nitrógeno (N), fósforo (P) y potasio (K) en cada órgano y se calculó la cantidad de nutrientes necesarios para alcanzar una tonelada de fruto comercial en este tipo de manejo. Los resultados indican que, la producción de fruto comercial por planta fue de 1.0 kg, el órgano que menos materia seca acumula es la raíz y el requerimiento nutrimental expresado en kg por tonelada de fruto fresco es N 0.78; P 0.12 y K 1.74.

Published: January 2025

Vertisols is one of the soils with problems in nutrient availability, necessitating nutrient input in the form of fertilizer. The continuous use of inorganic fertilizers can negatively impact soil quality and the environment. Thus, it is essential to reduce their use and balance them with manure. This study aims to evaluate the ef fect of combining inorganic fertilizers with manure on improving the availability of Vertisols nutrients and the growth and yield of sweet corn (Zea mays saccharata). The research was conducted in Sidokerto, Plupuh, Sragen, from March 2023 to August 2023, using a Randomized Complete Block Design (RCBD) with 9 treatments and 3 replications. The treatments included a control (A), NPK recommendation (B), manure (C), and combinations of manure and inorganic fertilizer at predetermined doses. The observation variables were C-Organic, CEC, Total-N, P-Available, K-Available, chlorophyll, and the growth and yield of corn. The results showed that the application of ¾ NPK + 1500 kg ha-1 of manure increased N-Total by 38%, P-Available by 38.68%, K-Available by 57%, chlorophyll by 29%, plant height by 28.25%, number of leaves by 20%, stem diameter by 22.89%, cob weight by 31%, cob length by 48%, and cob diameter by 29% compared to the standard NPK treatment. Application of manure and inorganic fertilizers can increase the availability of N, P, K nutrients in Vertisols, growth, and yield of sweet corn.

Published: January 2025

Los abonos verdes (AV), constituyen una alternativa a la fertilización convencional basada en el uso de fertilizantes de síntesis industrial que, por su excesivo e ineficiente uso, han contaminado el ambiente y agravado la erosión y degradación de los suelos. El presente trabajo tuvo como objetivo principal determinar, e tres AV inoculados y no inoculados con endomicorrizas y bacterias fijadoras de nitrógeno, el contenido de nutrientes en la biomasa aérea, a los 60 días después de su siembra. Para ello se estimó el contenido de nutrientes presentes en la biomasa seca de tres leguminosas; Mucuna pruriens (L.) DC. (MU), Vigna unguiculata L. (XPE), y Phaseolus lunatus L. (IB), Mucuna pruriens inoculada con endomicorrizas (EM) y bacterias benéficas fijadoras de nitrógeno (BFN) (MU+R), V. unguiculata inoculada con EM y BFN (XPE+R), P. lunatus inoculada con EM y BFN (IB+R). La mucuna, inoculada o no, presentó una relación C/N (18.33 y 21.73) cercano al óptimo para un abono verde, no obstante, XPE+R es superior en la producción de biomasa seca (6.25 Mg ha-1), nitrógeno (104.20 kg ha-1), fósforo (15.73 kg ha-1) y potasio (127.33 kg ha-1). Además de tener valor comercial en el mercado regional puede considerarse como posible alternativa de abonado más apropiada, respaldando así la capacidad de la tecnología ancestral maya, pues V. unguiculata, forma parte del sistema milpa en Yucatán.

El silicio (Si) tiene efectos benéficos en las plantas ya que les concede tolerancia a factores de estrés abiótico como la salinidad. El objetivo de este estudio fue determinar los efectos de la adición de Si sobre la eficiencia fotosintética, conductancia estomática, crecimiento y rendimiento de pepino (Cucumis sativus L.) cultivado bajo condiciones de salinidad. Se utilizaron tres concentraciones de Si (S: 0, 4 y 8 g L-1 [parcela principal]) y dos cultivares de pepino (C: GVS y Alpha Garden [sub-parcela]). La evaluación se realizó en dos tiempos: plantas cultivadas a salinidad de 2.5 dS m-1, y posteriormente a salinidad de 4.5 dS m-1. El incremento a la salinidad consistió en aumentar la concentración de macronutrientes en la solución nutritiva. Los tratamientos fueron distribuidos bajo un diseño completamente al azar con tres repeticiones. No se identificó interacción entre los factores evaluados (S × C), (P > 0.05). Bajo salinidad de 2.5 dS m-1, la adición de Si, no afectó la eficiencia fotosintética (Fv/Fm), la fluorescencia mínima (Fo), la conductancia estomática (gs). Sin embargo, bajo salinidad de 4.5 dS m-1, la adición de Si mejoró la gs. El cultivar GVS superó en rendimiento y número de frutos al cultivar Alpha Garden. La falta de respuestas fisiológicas del pepino por la aplicación de Si, posiblemente fue a que la salinidad se incrementó en la concentración de macronutrientes y no al incremento de otras sales comúnmente utilizadas como el cloruro de sodio.

Abstract
The food enzyme glucose oxidase (β‐d‐glucose: oxygen 1‐oxidoreductase, EC 1.1.3.4) is produced with the genetically modified Aspergillus niger strain ZGL by DSM Food Specialties B.V. A safety evaluation of this food enzyme was made previously, in which EFSA concluded that this food enzyme did not give rise to safety concerns when used in one food manufacturing process. Subsequently, the applicant has requested to extend its use to include one additional process. In this assessment, EFSA updated the safety evaluation of this food enzyme when used in a total of two food manufacturing processes. Dietary exposure was calculated to be up to 0.025 mg TOS/kg body weight (bw) per day in European populations. When combined with the no observed adverse effect level (NOAEL) previously reported (1038 mg TOS/kg bw per day, the highest dose tested), the Panel derived a margin of exposure of at least 41,520. Based on the new data, the revised margin of exposure and the previous evaluation, the Panel concluded that this food enzyme does not give rise to safety concerns under the revised intended conditions of use.

Published: January 2025

This study was carried out to analyze an online science, technology, engineering, and mathematics (STEM) teachers’ professional development using the DEmonstration, CO-train/design/teach, DEbrief (DECODE) model to empower teachers in refining technological pedagogical content knowledge (TPACK) skills. The model was performed due to the focus on STEM education as well as the ongoing challenges posed by the virtual environment era. The online DECODE model is mainly based on virtual lectures in combination with hard copies of instructors’ manuals, forming a blended training model. Therefore, the model empowered teachers to refine TPACK skills through familiarization with various software technologies and enhancing proficiency in instructional design. A total of ninety-one teachers from diverse educational settings, including urban, suburban, and rural schools, actively participated in a comprehensive 72-hour study. A willingness to engage in similar STEM-TPD sessions in the future was expressed after the analysis of open-ended questions. Furthermore, the paired sample t-test results showed a significant difference in TPACK ability before and after the training (t = 4.21; p = <.001; d = .82). The results showed that online teachers had increased the understanding and ability of TPACK after participating in online STEM-TPD workshop. Therefore, STEM-TPD with the DECODE model was essential to preserving teaching quality in the virtual and digital age.
Decimal multiplication and division in mathematics textbooks for prospective elementary teachers
Authors: He Jia
Published: January 2025

This study examined 11 U.S. textbooks written for prospective teachers to investigate how standard decimal multiplication and division algorithms are presented, especially the rationale of both algorithms. Analytical frameworks of various methods used in different textbooks were developed. The findings suggest that half of the textbooks do not fully present the standard algorithms. The results indicate variations in textbooks’ explanations for the procedures involved in the standard algorithms. Some procedures are explained more frequently than others. The reason why moving the decimal point in both dividend and divisor keeps the quotient unchanged is provided in most of the textbooks. Half of the textbooks explain why adding the decimal places in the multiplication algorithm. However, only two books explain the rationale for placing the decimal point in the quotient. The findings suggest that textbook writers pay more attention to explaining the rationales of the standard algorithms for decimal multiplication and division.
How to enable teachers to enhance all students’ understanding of percentages? A quasi-experimental field trial
Authors: Prediger Susanne , Kuhl Jan , Schulze Sarah , Wittich Claudia , Pulz Imke , Ademmer Claudia , Büscher Christian
Published: January 2025

Enhancing understanding is crucial for all students. Instructional approaches have been developed to achieve this goal, yet little is known about the kind of support that teachers need for their effective implementation. We compare two support conditions designed to enable teachers to enhance students’ understanding of the mathematical topic percentages. 51 teachers and their grade 7 classes participated in a quasi-experimental pre-post-test control group design, comparing three groups. (1) Teachers of the material condition received the curriculum material of the MATILDA teaching unit on percentages, with a comprehensive teacher manual on the main principles of the approach. (2) Teachers in the workshop condition received the same materials and additionally participated in professional development (PD) workshops covering key ideas of the approach. (3) The waiting control group used their regular textbooks. Hierarchical regressions were used to compare the effects on students’ learning outcome. The analysis reveals that students in both support conditions achieved significantly higher learning outcomes than the control group, i.e., curriculum materials and teacher manuals seem to provide effective support. No additional effect on student outcomes was found for the workshop condition, but a substantially lower teacher dropout than in the material condition. This finding indicates that PD workshops may not be necessary for highly motivated volunteer teachers but can be completed by a wider range of teachers. The findings can inform implementation projects for educational innovations and inspire further research to determine for which teachers a written PD is sufficient and for which face-to-face workshops are more promising.

El seguimiento a la gestión de los gobiernos locales en seguridad y convivencia
Authors: Leyva Botero Santiago , Pinzón-Villa Mariana , Fernando Agudelo Luis
Published: January 2025

Este artículo busca identificar las características de los esquemas intergubernamentales de medición del desempeño que valoran las capacidades de gestión local de la seguridad y la convivencia, con el fin de proponer un esquema de medición del desempeño para los gobiernos subnacionales de Colombia. Los gobiernos nacionales y federales necesitan herramientas de medición del desempeño de los gobiernos locales que le provean instrumentos objetivos a las relaciones intergubernamentales. Estos esquemas se desarrollan en un contexto en el que la securitización de las agendas públicas coincide con el mayor protagonismo de los gobiernos subnacionales en la gestión de la seguridad y la convivencia bajo los enfoques conceptuales de seguridad ciudadana y humana. América Latina vive una crisis de seguridad y convivencia a la vez que tiene dificultades para pasar de los esquemas de medición del desempeño de los gobiernos locales a los sistemas de gestión del desempeño, y esa dificultad es mayor a la hora de medir capacidades relacionadas con seguridad y convivencia. Las experiencias internacionales para medir las capacidades de los gobiernos locales en la gestión de la seguridad y la convivencia reflejan la existencia de un desajuste entre los objetivos de medición reflejados en las denominaciones de las dimensiones que pretenden entender de manera integral los problemas de seguridad local (contextos de desigualdad y pobreza, participación comunitaria o respeto de los DDHH) y unas mediciones expresadas en los indicadores que se concentran en la visión tradicional de los resultados de las expresiones criminales y los delitos de alto impacto

La evolución de los marcos de política pública de seguridad ha ido de la seguridad pública y del Estado a la seguridad humana pasando por la seguridad ciudadana, se expresa en términos de actores en el mayor protagonismo de las autoridades locales, de las comunidades, empresarios, ONG o cuerpos de seguridad privada, en el cambio de la escala territorial y la evolución de la relación integración social y seguridad en la esfera de los gobiernos centrales. En relación con los instrumentos de política, se ha transitado de capacidades monopólicas de gobierno directo de la policía y la justicia, hacia herramientas de mejora urbanística, participación comunitaria, gestión de las percepciones ciudadanas y de la integración social. Los aprendizajes para América Latina del proceso de transición hacia enfoques de seguridad ciudadana y humana están relacionados con complementar los esfuerzos de mejora urbanística, civilizar la policía, ampliar la participación a lo social, de forma que se aborde realmente el cierre de brechas y el combate al control de la gobernanza local por parte de grupos ilegales.
