Published: March 2024

Background: Chickpea is mainly grown on marginal lands and encounter the problem of erratic rainfall that causes lack of water availability especially at terminal growth stages. Exploration of yield stability and defining the adaptation domains of advance genotypes in different ecosystem is highly imperative for crop genetic improvement programs. Development of variety with high yield potential and stable under irrigated condition is one of the major objectives of chickpea improvement programme, which can be achieved by improving selection efficiency with estimating stability parameters. Ten chickpea genotypes as advance breeding lines and popular varieties were evaluated to assess seed yield stability under irrigated condition during rabi 2021-22. Methods: Experiments were conducted in randomized block design with three replications at five different locations of Karnataka i.e. Bidar, Kalaburagi, Bheemarayanagudi, Raichur and Hagari. The interaction analysis (AMMI ANOVA) indicates large variations for seed yield due to highly significant (p less than 0.01) environment (65.42%) and significant (p less than 0.05) genotype (10.03%), thus the genotypes were diverse with large sum of squares for seed yield and environment. Result: The differential response of chickpea genotypes for seed yield across the environments was observed. IPCA1 and IPCA2 together captured 12.97 per cent of the interaction mean squares RG-2016-134 and KCD-2019-05 showed higher mean yields and adaptable to favourable environments. Based on AMMI bi-plot analysis, genotypes (KCD-2019-05 and Super Annigeri-1) were stable and (DC-17-1111 and RG-2016-134) were unstable. Similarly, best performer genotypes and three mega environments were noticed through the analysis. Three environments i.e., (Bidar, Kalaburagi and Raichur) were found with most selective for seed yield estimation. The genotypes (RGV-203, KCD-2019-02 and Super Annigeri-1) were the best among all the ten tested genotypes in terms of seed yield stability.

Background: Pigeonpea, Cajanus cajan (L.) is a vital pulse crop in South Asia, with India accounting for 90% of it’s global production. Its protein content (21-25%) is essential for nutrition and plays significant role in improving food security and nutrition in regions with limited resources. The insect pest attacks in Pigeonpea cause significant amount of grain loss in field and storage, the research was carried out to investigate the carryover of pest from field to storehouses and to study the efficacy of oils on C. maculatus management in which literature available is scarce. Methods: This study was carried out at Sardar Vallabhbhai Patel University of Agriculture and Technology Meerut, U.P., India during the year 2020-2022. Pigeonpea seeds were collected from research farm threshing floor of ICAR-IIFSR, Meerut. Infestations of pulse beetle carried from field to storage was studied on basis of mean no. of eggs laid and mean seed damage caused by beetle. To study efficacy of oils, the seeds were subjected to linseed, mustard, soybean, rice bran, safflower, castor, mahua and neem oil each at concentrations of 0.20, 0.50 and 1.00 ml per 100 g of seeds and five pair of beetles of same age were released into each container and removed after 5 days to study the damage incurred. Result: In the carryover study, maximum oviposition (16.88 eggs) was recorded on freshly harvested seeds that were kept open in storehouse for infestations which witnessed field as well as storage egg laying. Oils application on seeds showed 1ml oil per 100 g seed as most suitable dosage and neem oil, castor, mahua as most successful oil providing beetle control in terms of oviposition, damage and adult survival. Residual action of oil on seed surface after 3 months revealed different oil treatments showed significant reduction in the number of eggs laid, adult emergence and seed damage due to C. maculatus in pigeonpea seeds in comparison to control. Mean reductions in the number of eggs, adult emergence and seed damage were relatively higher in all the oil treatments.

Examining Technology Use and Competence of Higher Education Academics During the COVID-19 Pandemic
Authors: Akgunduz Devrim , Kinik Topalsan Aysegul
Published: March 2024

Objectives: The present study describes the utilization frequency and competencies of educational technologies among academics at a university in Turkey during the COVID-19 pandemic. Methods: Participants were 391 faculty members and lecturers working in the faculties and vocational schools of a Turkish university during the 2020–2021 academic year. A survey included questions regarding the use of educational technologies and perceived competency in the use of those technologies. Results: Academics are more familiar with distance education than hybrid or blended learning. Academics reported that blended learning, hybrid learning, and distance education provide more effective education on integrating technology but report that they mostly prefer face-to-face teaching after the COVID-19 pandemic. The top three self-reported competencies are MS Office, the university academic information system, and meeting and course management tools. More information is needed about educational technology approaches and various applications such as augmented reality, simulations, assessments, and video tools. Conclusion: Faculty use of digital tools is limited, they experience significant deficiencies in using various digital tools and systems, and they are less competent in applying these tools. Academics still consider traditional face-to-face teaching as the primary choice if they are free to make decisions in the context of education and training. Thus, there is a need for professional development focused on pedagogical educational technology approaches, models, and methodologies. Implications: Various factors such as the course type, subject matter, education level, technical infrastructure, and technological and methodological support should be evaluated within the context of digitizing universities.

Authors: Bieńkowska Agnieszka , Tworek Katarzyna
Published: March 2024

The article concerns the role of employees’ dynamic capabilities in boosting the perceived job security of employees in contemporary organizations. It is assumed that the fit between employees and their job (P-J fit) and employees and their supervisor (P-S fit) in mediating the influence of employees’ dynamic capabilities on perceived job security. Such a theoretical model is empirically verified based on the sample of 1,197 organizations operating in Poland, Italy, and the USA in 2021 when job security was crippled by COVID-19. The results confirm that employees’ dynamic capabilities remain crucial for boosting perceived job security and such relation is mediated by P-J fit and P-S fit.

UN MODELO UNIFICADO ESTRUCTURAL DE SUPERFICIE PARA LA FERRIHIDRITA: CARGA PROTÓNICA, ENLACE ELECTROLÍTICO, ADSORCIÓN DE ARSENATO
Authors: Villalobos Mario , Antelo Juan
Published: March 2024

La ferrihidrita (FH) es un nanomineral de óxido férrico hidratado común en ambientes geoquímicos acuosos. Sus pequeños tamaños de partícula (1.5-5 nm) exponen una gran área superficial específica en la interfaz mineral/agua, y esto puede tener una influencia considerable en el transporte y destino de una variedad de elementos vestigiales y mayores, a través de diversos procesos de sorción. En particular, los aniones de arseniato muestran una gran afinidad por las superficies de óxidos de Fe(III), incluyendo a la FH, y su destino en ambientes contaminados está casi invariablemente asociado a éstos. Las nanopartículas extremadamente pequeñas de FH, que muestran un alto grado de agregación cuando se secan, impiden la determinación experimental de parámetros superficiales importantes para la descripción termodinámica de su comportamiento de adsorción, tales como el área superficial específica disponible en suspensión. En el presente trabajo hemos recopilado ocho series de datos de titulación superficial ácido-base publicadas de preparaciones sintéticas de FH en un amplio intervalo de tamaños de partícula y hemos unificado su descripción a través de un modelo de distribución de caras cristalinas - densidad de sitios desarrollado previamente para la goetita. Mostramos que el comportamiento de carga superficial protónica de la FH junto con su comportamiento de adsorción de As(V) se puede describir adecuadamente utilizando las constantes de afinidad derivadas para la goetita, asumiendo la superficie de la FH como compuesta predominantemente de grupos superficiales monocoordinados >OH, con una densidad de sitios igual al de la cara (010) de la goetita (grupo espacial Pnma). Además, a través del modelo aplicado se puede derivar exitosamente el área superficial específica disponible de cada preparación de FH en suspensión acuosa, mostrando valores entre 330 y 1120 m2/g. La implicación de los resultados que se reportan aquí es altamente relevante para la predicción general de la reactividad superficial de la FH.

Authors: Reyes Jaime Alejandra , Aguilar Ibarra Alonso , Anglés Hernández Marisol , Güereca Hernández Leonor Patricia
Published: March 2024

En México existe una tendencia por reformar las legislaciones estatales de gestión de residuos con la intención de frenar la dispersión de plásticos de un sólo uso (P1U) y fomentar la reducción de residuos mediante acciones de corresponsabilidad. Actualmente, 29 de los 32 estados mexicanos establecen en sus leyes la participación de sectores de la sociedad para motivar una gobernanza de los plásticos. Sin embargo, aún no existe un estudio nacional que brinde información sobre la forma en la que se está distribuyendo la responsabilidad dentro de las legislaciones. Por ello, el objetivo de este estudio fue evaluar a través de un análisis de redes la diversidad de actores y su inclusión como sectores dentro de la legislación que hasta ahora regula los P1U en México. Los hallazgos de la investigación indican que para frenar la dispersión de P1U el 90 % de las entidades federativas, de acuerdo con su legislación, se apoyan en el sector económico de la distribución y comercialización. Además, a nivel nacional, se observó una subrepresentación de la responsabilidad de los sectores productivo y académico. En este sentido el presente estudio ofrece una propuesta metodológica para visualizar de forma resumida y esquemática la diversidad de actores y sectores en el complejo panorama de la corresponsabilidad para la reducción de P1U. La herramienta de análisis de redes podría ser aprovechada para facilitar la tarea de los tomadores de decisión o para investigaciones que consideren la revisión legislativa cuantitativa.

Published: March 2024

This research is motivated by reasons of low mathematical reasoning and ability to solve mathematical problems. Learning is still centered on the teacher who only provides mathematical formulas without providing the concept of discovery and problem solving. The use of a learning approach that is not optimal. Mathematics is a subject that is difficult to solve the problem. Most teachers in elementary schools use student worksheets (LKS) in the learning process. The problem used in the student worksheet (LKS) is a closed problem. The unavailability of student worksheets developed based on an open-ended approach that emphasizes mastery of concepts and reasoning to solve problems. The research method is quantitative research in the form of experimental research with a Non Equivalent Control Group Design. Data collection techniques with tests. The research subjects were students at SDN 1 and SDN 2 Kebloran Rembang. Sampling technique with purposive sampling. Data analysis using the Paired Sample Test. Test the effectiveness of getting the value of Sig. (2-tailed) of 0.000 <0.05. The decision was that Ho was rejected and Ha was accepted because Sig. (2-tailed) < 0.05 and t count > t table. The conclusion of this study is that there is a difference between the group and the experimental group, which shows a significant increase in students' mastery of mathematical concepts from the Development of Student Worksheets with the Open Ended approach.

Abstract. The purpose of writing this article is to describe: developing models and formulating rough forms of design models of inductive approaches to learning mathematics for elementary school (SD) teachers whose backgrounds are not from mathematics or mathematics education. The research partners are Mutiara Persada Elementary School teachers, Kasihan Subdistrict, Bantul Regency. The research approach is mixed qualitative and quantitative with the type of research and development. Data collection techniques for first year research are using:
questionnaires, interviews, and documentation. The development model used is the ADDIE model by Dick & Carry (1996). The results of the study, namely: (1) maximizing mathematical understanding needs to pay attention to Piaget's learning theory, (2) the mistakes made by the teacher are how to make the relationship between symbols and procedures and the availability of appropriate references, linking symbolic procedures with informal problem solving, and connecting between symbol system, (3) inductive message processing, i.e., it starts with facts or special events which are then related to the previous material (prerequisite material), conceptualization based on facts that are in accordance with reasoning and the results of empirical case development, and compilation of generalizations based on concepts concepts, and (4) the construction of a crude model of mathematics learning with an inductive approach, the stages of which are:decomposition of the problem; determination of prerequisite material;
fixing the facts of the problem; motor, affective, and cognitive domain integration activities; reasoning process; evaluation of the reasoning process; empirical case development; concept formulation; and evaluation of learning.
