Abstract

Inclusion in the teaching-learning process is an urgent need in contemporary education, challenging schools and educators to promote equity and respect for diversity, as advocated by Mantoan (2021) and Mittler (2020). This project seeks to understand pedagogical practices that ensure the effective participation of all students, overcoming the limited view of inclusion as merely inserting students with disabilities into regular classes. According to authors such as Rodrigues (2023), inclusion requires curricular, methodological, and pedagogical resource adaptation, ensuring that the specific needs of each learner are met. Accessibility, both physical and pedagogical, is essential to eliminate barriers to learning, as highlighted by Booth (2022), and is one of the pillars of school inclusion. In addition, ongoing teacher training and the collaborative work of multidisciplinary teams, according to Moran and Bach (2018), are essential to create a welcoming and inclusive educational environment. These actions should value students' abilities, promote mutual respect and ensure their integral development. Inclusion in teaching and learning, as pointed out by Sassaki (2021) and UNESCO (2022), is not only a legal duty, but also an ethical and social responsibility. Investing in inclusive practices means ensuring that all students, regardless of their conditions, have full access to learning and can actively participate in society, contributing to the construction of a more just and egalitarian world.

Corporate Venture Capital as Driver of Strategic Change? An Interorganizational Learning Perspective
Authors: Schmidt C. , Kaiser C. , Bausch A.
Published: February 2025

Incumbent firms use corporate venture capital (CVC) as an interorganizational learning mechanism to get access to new technologies or to study and enter foreign markets. When companies adapt their product portfolios or expand their business activities geographically, strategic change takes place. Nonetheless, research still lacks an understanding of CVC's impact on both dimensions of strategic change. Building on learning theory, we examine the impact of CVC activity on product portfolio change and geographic change using a sample of 1,458 CVC units and 6,751 transactions. Our study empirically shows that technology-related CVC investments lead to subsequent product portfolio adjustments, while investments in foreign start-ups drive geographic change. Our paper also finds that these positive change effects diminish with increasing industry and cultural distance, as higher investment uncertainty and risk arise from identifying (excessively) heterogeneous knowledge. Thus, increasing distance reduces the effectiveness of interorganizational learning and impedes strategic change. However, our paper confirms that CVC represents an effective catalyst for knowledge acquisition and related strategic change, offering practical insights for firms seeking to leverage CVC as a low-cost mechanism for product and geographic diversification.

Characterization of the Diversity of Microbial Communities in the Rhizosphere of Solanum betaceum in Response to Inoculation with Microbial Consortia Under Cultivation Condition
Authors: Calle Gill Diana Carolina , Chica Martínez Eduardo José , Bonilla Jaime Julio Andrés
Published: February 2025

Bioinoculation with native or introduced microorganisms is a promising alternative to using synthetic chemicals in agriculture, although its impact on the microbial communities of the rhizosphere is still poorly understood. This study analyzed the microbial community of the rhizosphere of Solanum betaceum (tree tomato) over 120 days, using a metagenomic approach to evaluate microbial diversity and the persistence of Trichoderma spp. through PCR. The predominant phyla identified were Pseudomonadota and Actinomycetota, and the most abundant genera were Streptomyces, Nocardioides, Bradyrhizobium, Sphingomonas, Rhodanobacter, and Micromonospora. While the microbial composition changed over time, diversity indices did not show significant differences before and after inoculation, and the establishment of Trichoderma spp. in the rhizosphere was not observed. These findings provide insight into the complex interactions between residents and introduced microorganisms, offering a basis for future studies. The results suggest that frequent inoculation alone was insufficient to change the diversity of rhizosphere microbial communities noticeably. It is recommended that research be expanded to other geographical conditions to deepen the understanding of the microbial profile of the S. betaceum rhizosphere and its application in different crops.

Keywords: Bioinoculation, rhizosphere, microbial communities, Solanum betaceum, metagenomics.
Potential of Curcuma Temulawak Extract on Melatonin and Hyaluronidase Levels in Human Skin Fibroblast Cell Line Exposed to UV Light as an Aging Model
Authors: Lumbantobing Eva Christine Natalia , Chiuman Linda , Fachrial Edy
Published: February 2025

Skin aging is characterized by a decrease in the skin's ability to regenerate and maintain its structure, which is influenced by endogenous factors (genetic mutations, hormonal factors) and exogenous factors (UV exposure, pollution). UV radiation accelerates skin aging by generating reactive oxygen species (ROS) that can activate hyaluronidase and induce inflammation, leading to cell apoptosis. Natural antioxidants such as melatonin play an important role in skin protection, but melatonin levels decrease with UV exposure. The temulawak plant contains compounds that can be utilized as antioxidants. This study aims to determine the potential of Curcuma xanthorrhiza (temulawak) natural extract to reduce UV-induced skin aging by increasing melatonin levels and reducing hyaluronidase activity. Extraction was performed using maceration method with 70% ethanol solvent. Aging model cells were prepared from human skin fibroblast cell cultures that were exposed to UV light 300J/cm2 for 75 minutes. The treatment given to the aging model cells, namely temulawak extract in 3 different concentrations 12.50; 6,25; 3.13 μg/mL. The results showed that temulawak extract significantly increased melatonin level in fibroblasts exposed to UV light, with an optimal concentration of 12.25 µg/mL (147.71 pg/mL metionin). In addition, temulawak extract also significantly reduced hyaluronidase levels with the same optimal concentration (95.78 ng/mL). Curcuma longa extract may serve as an effective natural agent for anti-aging skin care products by increasing melatonin levels and reducing hyaluronidase activity, thus potentially improving skin health and reducing the effects of aging caused by UV exposure.

This study explored Students’ Motivation for Effective Learning of Basic Science and Technology (BST) among junior secondary school students in Oredo Local Government Area of Edo State, Nigeria. Two research questions were raised, and one hypothesis formulated to guide the study. The sample for the study is three hundred and fifty-two (168 males and 184 females) junior secondary school students from the twelve (12) public junior secondary schools. The survey research design was adopted for the study while the simple random sampling technique was used in selecting the sample. A 10-item Basic Science and Technology Students’ Motivation (BSTSM) Questionnaire was adopted for the study. To establish its reliability, the instrument was administered to 20 students in the study population who were not part of the study sample. Using Cronbach’s alpha statistic, the reliability was computed and found to be 0.71. The instrument was therefore accepted as reliable and administered to BST Junior Secondary Schools two students by the researcher, with the assistance of the teachers and thereafter they were collected and collated for analysis. The data was analyzed using descriptive statistics of mean and standard deviation, while t-test was used in testing the hypothesis at 0.05 level of significance. The findings revealed that students are well motivated for effective learning of BST. It was also found that there is no significant difference between male and female students’ levels of motivation for effective learning of BST. It is recommended among others that the gender balance for students’ motivation for effective learning should be sustained and school management should always provide a conducive learning environment that will be a good recipe for continuous motivation of the students for effective learning.

Authors: SALAUDEEN ABDULRAUF ADEWALE
Published: February 2025

This paper delves into the intricate relationship between Islam and democracy, focusing on the role of Maqasid al-Shari’ah in shaping Islamic political thought. It explores how this framework, emphasizing the core objectives of Islamic law, intersects with democratic values and principles. The study begins with a historical overview of Islamic political thought, tracing the evolution of the Maqasid al-Shari’ah and its integration into various Islamic political models through history. It then examines the perspectives of three primary schools of thought in Islamic political theory: the normativists, who advocate for a traditional interpretation of Islamic texts; the acculturalists, who emphasize the adaptation of Islamic principles to contemporary contexts; and the neo-normativists, who seek a reevaluation of classical Islamic interpretations in light of modern challenges. The paper further analyzes the compatibility of Maqasid al-Shari’ah with democratic principles, discussing its application in modern Islamic states and the challenges and criticisms it faces. A comparative analysis between Islamic and Western democratic models is conducted, highlighting the influence of Maqasid al-Shari’ah on democratic practices in Muslim countries and its role in cross-cultural and interfaith dialogues. The paper concludes with a discussion on contemporary challenges and future directions, focusing on the political, social, and economic challenges in Muslim democracies, the role of education and public discourse, and recommendations for future research.

The design adopted in this study was quasi-experimental design using a pretest-posttest, control group with 3 X 2 factorial matrix. The variables of the study comprised independent variable (instructional strategies operated at three levels), moderating variable (gender operated at two level) and dependent variable (achievement in Mathematics). The population of the study consisted all primary three pupils in the five states (Anambra, Imo, Abia, Enugu and Ebonyi) of South- East geopolitical zone in Nigeria. Sampling was carried out at multi-stage levels. Two states were randomly selected, the primary schools in each of the selected states were clustered according to the local government areas.  One local government areas were randomly chosen from each of the selected states making a total of two local government areas. Three (3) primary schools were randomly chosen from each of the selected local government areas making a total of six (6) primary schools. The selected schools were randomly assigned treatments. The intact classes of the selected primary schools were used for the study. The sample size was one hundred and forty-four pupils (144). Three stimulus treatment packages (Collaborative Team Instructional Package (CTIP), Indigenous Instructional Package (IIP) and Conventional Instructional Package (CIP). Mathematics Achievement Test (MAT with Lawshe’s Content Validity Index 0.85; r = 0.89) was developed by the researchers and served as a response instrument. Data were analysed with Analysis of Covariance (ANCOVA) using pretest as covariates. The findings of the study showed that instructional strategies showed a significant effect on pupils’ achievement in Mathematics. Pupils taught with bilingual instruction (F (1, 137) = 123.161, p<0.05) produced better performance than those taught with collaborative team and foreign language instructions. The study concludes that bilingual instruction produced a better performance than collaborative team and convectional instructions. The study recommends that bilingual instructional strategy should be used by Mathematics teachers in Basic schools to produce better achievement in Mathematics.

En el presente trabajo, se busca determinar los coeficientes de frecuencia natural de vibración transversal de placas FG rectangulares delgadas, con variación continua de sus propiedades mecánicas a lo largo de su espesor y presencia de huecos en su dominio. Las placas FG deben su denominación a que se encuentran construidas con materiales funcionalmente graduados. El análisis propuesto es una continuación de trabajos presentados anteriormente que agrega la presencia de singularidades en el dominio de la placa, dadas por la existencia de uno o más huecos de forma rectangular, que resulten necesarios debido a diferentes requerimientos de diseño. Para obtener dichos valores, se recurre a la modelización numérica, mediante la aplicación del método de Ritz y del método de elementos finitos. En los casos en que resulte posible, se comparan los valores obtenidos con los hallados en la literatura técnico-científica disponible.

La ocurrencia de terremotos en zonas sísmicas densamente pobladas del mundo y en las del oeste argentino, han puesto en evidencia grandes pérdidas económicas y de vidas humanas. Con el objeto de controlar y minimizar el daño ocasionados por los terremotos se han desarrollado distintas técnicas de protección sísmica basadas en la disipación de energía y/o el aislamiento sísmico. La investigación se encuadra dentro de un proyecto más amplio que abarca el diseño, la fabricación y la caracterización mecánica y no lineal de aisladores sísmicos, todos ellos fabricados con tecnología local. El trabajo muestra los resultados de los ensayos de distintos prototipos de aisladores elastoméricos sujetos a cargas verticales de compresión y horizontales cíclicas. Los resultados obtenidos se contrastan con los obtenidos mediante análisis numéricos de elementos finitos. Los ensayos experimentales permitieron la validación del modelo numérico propuesto y también la caracterizar de las leyes constitutivas de los dispositivos.

Los paneles estructurales con aislación resultan un material alternativo para la construcción de viviendas residenciales y construcciones industriales livianas. Estos paneles están compuestos por un núcleo de poliestireno expandido de alta densidad contenido dentro de un marco perimetral de madera y dos tableros exteriores formados por virutas de madera mezcladas con un adhesivo fenólico y poliuretano prensadas a alta temperatura y presión. Los dos tableros se adosan al núcleo con adhesivos de alta resistencia. En este trabajo se representan resultados de simulaciones en elementos finitos del comportamiento de un panel sometido a ensayos estáticos de cargas verticales excéntricas y de flexión. El panel se modela con elementos sólidos hexaédricos de aproximación lineal con un código de propósitos generales. Se realiza un análisis de bifurcación lineal y análisis no lineal geométrico, y los resultados numéricos se comparan evaluaciones experimentales para las dos configuraciones de carga.

Una estructuración frecuente para la cubierta de tanques industriales de almacenaje de combustible es la de un domo autoportante que, compuesta por un entramado de perfiles y chapa de acero, logra resistir una variedad de acciones externas junto a su peso propio sustentándose únicamente en su perímetro. Existe una amplia variedad de diseños estructurales para este tipo de cubierta, lo que la convierte en una tipología ampliamente discutida en trabajos de optimización estructural. Este trabajo se centra en la optimización de la cubierta autoportante tipo domo de un tanque industrial de 50 metros de diámetros y 17.5 metros de altura. Los parámetros a optimizar son el espesor de la chapa, la rigidez del anillo de borde de la cubierta y el radio del casquete esférico, utilizando un modelo numérico paramétrico con elementos de cáscara MITC lagrangeanos cuadráticos en el software COMSOL Multiphysics. Se analiza la respuesta estática de la estructura bajo dos combinaciones de cargas críticas conforme a la norma API-650, incluyendo sobrecargas, presiones internas y la acción del viento. La evaluación del desempeño se basa en los factores críticos de carga de pandeo lineal, con el objetivo principal de minimizar el peso total de la estructura. El estudio concluye identificando una configuración óptima que equilibra la eficiencia en el peso con márgenes de seguridad, brindando interesantes conclusiones para el diseño de cubiertas de grandes luces y sin apoyos intermedios.
Influencia de la No Linealidad Geométrica en Cubiertas Autoportantes de Tanques de Grandes Dimensiones

Se analiza la influencia que la no linealidad geométrica tiene en el abollamiento de la chapa de la cubierta tipo domo autoportante de un tanque de almacenaje de combustible de 17.5 metros de altura y 50 metros de diámetro con pared cilíndrica de chapa. Se utilizan para el modelado elementos de cáscara tipo MITC lagrangeanos cuadráticos en el software COMSOL Multiphysics y se preserva como hipótesis la linealidad física de los materiales. Las cargas son consideradas conforme a la norma API-650. Se contrastan los valores de carga crítica obtenidos mediante tres tipos de análisis diferentes: pandeo lineal con paso inicial lineal, pandeo lineal con paso inicial no lineal geométrico en diferentes puntos de linealización y análisis no lineal con control de desplazamiento. Se observa que un análisis de pandeo lineal puede resultar insuficiente, no solo para estimar con precisión el valor numérico de la carga crítica sino también la zona de la estructura espacial que resultaría abollada, independientemente de haber considerado un paso inicial lineal como no lineal geométrico.
