Authors: Ontolan Jay , Malusay Jeneveb , Kiunisala Edward , Buloron Joris
Published: February 2025

In this paper, we introduce a new class of Frobenius-Tangent polynomials, derived from the Bell numbers and Apostol-type functions. We conduct a detailed investigation into the properties of these polynomials, utilizing various analytical techniques. By employing generating functions for Bell-based Apostol-Frobenius-Type Tangent polynomials of higher order, we obtain both explicit and implicit summation formulas and its relation to Appell polynomials.
Statistical Inference Based on Censored Data of Entropy for Lomax Distribution
Authors: Ahmed Samah M. , Ismail Gamal
Published: February 2025

The current research centers around entropy, which is officially defined as an indicator of the possible amount of information of the Lomax (Lo) distribution that quantifies the uncertainty of random variables. When the parameters are unknown under adaptive progressive Using type-II censored data, the entropy maximum likelihood estimate (MLE) is computed and the bootstrap confidence intervals of entropy is displayed. The Bayes estimator of entropy is demonstrated using both the symmetric and asymmetric loss functions. In the meantime, the posterior is also computed to assess how well the entropy estimators perform in relation to various loss functions. The Bayesian estimates were obtained in a numerical simulation applying the method of Markov Chain Monte Carlo (MCMC). Then, using Monte Carlo simulations, various approaches are compared to identify the believable intervals of the entropy's highest posterior density (HPD). Lastly, the recommended methods are illustrated using a numerical example.

Authors: Esquivel-Gámez Ismael , Vázquez-Ariza Jorge Luis , Guerrero-Posadas Martín , Berthely-Barrios Julio César
Published: February 2025

El teléfono inteligente tiene un papel muy importante en la vida de los jóvenes, lo que preocupa por sus efectos en la salud y el rendimiento académico. El objetivo del presente estudio fue validar un instrumento piloto de medición para determinar la prevalencia de la adicción al teléfono inteligente entre bachilleres y universitarios, además de examinar su relación con las preferencias sensoriales (visual, auditiva, lectora, kinestésica). Se realizó un estudio con 141 estudiantes de bachillerato y universidad de México. Se aplicó una encuesta sobre adicción al celular y un cuestionario sobre las modalidades de percepción. Aunque el nivel de adicción promedio fue mayor en universitarios, no hubo diferencia significativa por género. La prevalencia de adicción general fue del 22 %, con “tolerancia” y “síndrome de abstinencia”, como síntomas más comunes, aunque sola la primera tuvo diferencia significativa estadística (P < 0.05). Respecto a las preferencias sensoriales, las más indicadas fueron auditiva (29.6 %) y kinestésica (27.6 %), siendo la cantidad de uno y cuatro canales perceptivos, los más elegidos. Los universitarios prefirieron la información visual más que los bachilleres (P < 0.05), mientras que la preferencia por la lectura/escritura fue mayor en bachilleres (P < 0.05). Considerando la puntuación total obtenida en la encuesta como un indicador de adicción al celular, se observó que las personas que prefieren los contenidos visuales usan más el teléfono inteligente (ρ = 0.20, P = 0.015), mientras que las que disfrutan de la lectura/escritura lo usan menos (ρ = - 0.17, P = 0.048). Dichos hallazgos podrían guiar el desarrollo futuro de aplicaciones para estos dispositivos, de modo que los estudiantes reorienten el uso del teléfono inteligente en beneficio de su propio desarrollo, aprovechando los canales de percepción preferidos, aunque por supuesto, se necesitan más estudios similares en otras regiones de México.
Violencias, perspectiva transdisciplinar y diferencial de construir la prevención
Authors: Monroy Ojeda Carla
Published: February 2025

La prevención es el fin último de la criminología; se cuestiona con un ¿por qué?, para poder generar un abanico de estrategias y acciones que incidan en las causas criminógenas, sin embargo, parte del inicio de esta planeación y desarrollo es analizando e identificando las violencias. La violencia busca causar daño, tanto en cada individuo como en el tejido social, el cual corrompe y debilita, haciendo más difícil la articulación de acciones que prevengan y mitiguen la delincuencia.
Si las violencias son múltiples, también las acciones que se deben diseñar y ejecutar en torno a ellas. Las violencias son conductas, son condiciones, son prácticas que se pueden entender como factores de riesgo, y teniendo una lectura más clara de las diferentes formas de violencias que se presenten en un espacio, mejores y mayores formas de intervención se podrán ejecutar.
Desafíos que enfrentan los ex reclusos al regresar a la sociedad y como estos contribuyen a la reincidencia
Authors: Celaya Flores Hilary Briseidi , Méndez González Johana Nataly
Published: February 2025

La reintegración de ex reclusos a la sociedad es un proceso complejo que enfrenta numerosos desafíos sociales, económicos y personales. Estos obstáculos pueden tener un impacto significativo en las tasas de reincidencia y regresar al sistema penitenciario. Sin embargo, es importante considerar que no todos los desafíos que enfrentan los ex reclusos derivan de necesidades económicas o falta de recursos. En muchos casos, otros factores como la estigmatización social, el estancamiento personal y la falta de apoyo emocional desempeñan un papel fundamental en la difícil transición hacia una vida libre de criminalidad. Este artículo explora los principales desafíos que enfrentan los ex reclusos al reincorporarse a la sociedad y analiza cómo estos factores contribuyen a la reincidencia.

Authors: Caloca Lafont Eloy
Published: February 2025

La enseñanza de las Humanidades Digitales (HD) en México comenzó hace década y media, impulsada por asociaciones como la Red HD y centros educativos como la Universidad Nacional Autónoma de México (UNAM), El Colegio de México (Colmex), el Tecnológico de Monterrey (Tec), la Universidad de El Claustro de Sor Juana y la Universidad de la Rioja, México (UNIR). También, fuera de la capital del país destacan espacios como las Universidades Autónomas de Querétaro (UAQ) y Nuevo León (UANL). En este artículo se analizan los esfuerzos de estas y otras instituciones por fomentar cursos, talleres y proyectos de HD, considerando: a) su conceptualización del campo interdisciplinario (es decir, sus bases epistemológicas y pedagógicas); b) su infraestructura; y c) algunas experiencias de profesores y alumnos. Asimismo, se relatan los inicios de las HD en México y los avances en el área; por ejemplo: la apertura de capacitaciones introductorias, la consolidación de un pensamiento crítico y decolonial en el campo, y la asesoría integral de investigaciones o el contraste entre metodologías. Por otro lado, se evalúan las dificultades que persisten, como la centralización del área, la falta de recursos materiales e inmateriales, y la dependencia tecnológica y financiera de instituciones públicas y privadas.
Humanidades Digitales y Literatura Infantil: análisis de traducciones de 'El patito feo' y la influencia de H.C. Andersen en México
Authors: Flores HIlerio Dalina , Contreras López Azael Abisaí
Published: February 2025

Hans Christian Andersen se considera el padre de la literatura infantil contemporánea, por la variedad y amplitud de su obra así como por su estilo narrativo ameno y profundo. Estas cualidades han hecho de su obra la más traducida en el ámbito de la literatura infantil, como una muestra de que la literatura contemporánea escrita para niños carece de las fórmulas pedagógicas y moralizantes tan vigentes en la literatura infantil clásica; sin embargo, hemos notado que se han realizado diversas traducciones al español, con intenciones discursivas tendientes a promover modelos y sistemas axiológicos donde se reflejan las dinámicas y valores de sus respectivos contextos socioculturales. Estas diferencias también nos llevaron a encontrar que muchas de las versiones en español de “El patito feo” no se han derivado directamente del danés, su idioma original, o bien, son versiones libres de la historia original. Por ello, en esta investigación nos hemos allegado de las herramientas que nos ofrece la tecnología digital para nutrir el corpus con el que estamos trabajando. En este artículo describimos la metodología y algunos obstáculos que hemos encontrado para analizar comparativamente los efectos discursivos de algunas traducciones de este popular cuento infantil, escrito por Andersen; asimismo, describimos el diseño de una interfaz, a partir del lenguaje de programación de código abierto Python y la librería Tkinter, de acceso libre, para solicitar la colaboración de otros investigadores interesados en el análisis comparativo de los cuentos de Andersen traducidos al español.

University Student Stress and Behavioral Health During the COVID-19 Pandemic
Authors: Vora Sana , M. King Christopher , Bomysoad Rachel , Pozzo Jill Del
Published: February 2025

Higher education students have experienced increased stressors and behavioral health problems during the COVID-19 pandemic. The current study further investigated such phenomena in a sample of university students collected between June 2020 to December 2021. Students (N = 1,441) from a Mid-Atlantic public university were recruited via email lists and a psychology department research participant pool. The participants completed an online survey with items pertaining to demographic factors, biopsychosocial stressors, and measures of behavioral health functioning. All variables were examined descriptively, and regression analyses were used to examine hypothesized cross-sectional relationships between demographic factors and biopsychosocial stressors, on the one hand, and behavioral health functioning, on the other. Experiencing notable levels of biopsychosocial stressors was common, though a linear trend across semesters was not observed with respect to behavioral health functioning. Gender was the most consistent demographic predictor of behavioral health functioning, whereas the most common biopsychosocial stressor predictors for behavioral health functioning were stress/worry, social isolation, discrimination, and prior mental health services. Results corroborate and extend prior research evidencing notable levels of biopsychosocial stressors and behavioral health problems reported by higher education students during the COVID-19 pandemic. Implications for campus administrators and behavioral health providers concern vulnerabilities for a range of pandemic-time challenges being experienced by their constituents to which to attend.

A Sobrecarga Mental de Mulheres Brasileiras na Contemporaneidade e as Contribuições da Terapia Narrativa
Authors: Lopes Eliana Maria , Becker Ana Paula Sesti
Published: February 2025

A sobrecarga mental em mulheres brasileiras é um fenômeno de risco para o adoecimento psíquico, além de provocar prejuízos no âmbito pessoal, familiar e profissional. A naturalização de papéis e funções femininas deriva-se de valores culturais, religiosos e interesses econômicos que mantêm as mulheres subordinadas à cultura patriarcal. Sob este cenário, a Teoria Narrativa surge como uma possibilidade para o enfrentamento dessa problemática ao apontar estratégias e novas perspectivas relacionais que contribuem no manejo das adversidades e queixas psicopatológicas. Desse modo, o presente ensaio teórico tem como objetivo discutir os impactos da sobrecarga mental na vida de mulheres brasileiras na contemporaneidade e as contribuições da Terapia Narrativa para a saúde mental feminina. Portanto, os principais resultados indicaram a permanência de paradigmas culturais e estigmatizadores que discriminam e pouco valorizam o trabalho feminino, seja nas ocupações profissionais e domésticas ou no cuidado dos filhos e da família. É neste panorama que a Terapia Narrativa pode lançar novos olhares e favorecer a construção de histórias alternativas para a superação das barreiras de desigualdades e violências, além de promover a saúde mental da mulher.
The impact of mathematical disposition and self-efficacy beliefs on secondary school students' mathematical literacy
Authors: Nurhayati Hanifah , Hasanah Aan , Dasari Dadan
Published: February 2025

The mathematical literacy skills of Indonesian students, as reflected in the PISA results, continue to be a concern because of their poor performance. Students with high mathematical disposition and high self-efficacy are often more proficient in mathematical literacy. This study aimed to examine how mathematical disposition and self-efficacy affect students’ mathematical literacy skills. This study employed a quantitative approach with a nonexperimental design and adopted a causal associative methodology. Data collection involved administering mathematical disposition and self-efficacy questionnaires, along with a mathematical literacy test, to 56 junior high school students. The analysis was performed using structural equation modeling-partial least squares (SEM-PLS) in the JASP 0.18.3.0 application. The results showed that mathematical disposition significantly enhances both self-efficacy and mathematical literacy skills. Conversely, while self-efficacy positively influenced mathematical literacy skills, the effect was not statistically significant.
Abstraction level of van Hiele’s theory: Occurrence of side effects in GeoGebra integration
Authors: Kandaga Thesa , Novianti Idha , Adnan Mazlini
Published: February 2025

One of the obstacles to teaching geometric transformation is the complex procedures that require a broad base of prerequisite knowledge. This complexity often leads students to focus on rote memorization and procedural calculations instead of understanding the underlying context. This study aims to overcome these challenges by developing a hypothetical learning trajectory (HLT) and using GeoGebra to enhance visualization and understanding. The case study involved ten university students in Indonesia who tackled the abstraction level in the Transformation, Isometries, and Reflection topics. The researchers analyzed students' worksheets, activity observations, and learning obstacle tests to extract their geometric thinking. Qualitative analysis of the data revealed that seven out of ten participants met three of the four abstraction level indicators. The use of GeoGebra in HLT helped overcome epistemological obstacles. However, integrating GeoGebra into the HLT introduced a new issue: a GeoGebra-centric habit characterized by an excessive dependence on GeoGebra in solving geometric transformation problems.

Published: February 2025

Although many studies have involved fractions in the elementary school curriculum, research on this topic at the junior high school level has been limited, particularly in identifying the factors causing student learning difficulties and designing alternative didactic approaches to overcome these challenges. Therefore, this study aimed to investigate these aspects. Hermeneutic phenomenology was used in this study. The participants in this research were students from a junior high school in Lombok, Indonesia, consisting of 29 eighth-grade students (aged 14-18), most of whom were female and from the Sasak ethnic group. Instrument, such as fraction operation tests, in-depth interview guidelines, and a hybrid didactic design for mathematics learning. Data related to learning difficulties were analyzed using a thematic analysis approach with NVivo-12 software. The study's findings revealed that students' low ability to operate integers, especially multiplication and division, was a primary factor in learning difficulty. The hybrid mathematics learning design sequence consists of three stages. The first stage encompasses several activities, namely Let’s Guess and Let’s Read. The second stage involved activities like Let’s Search, Let’s Discuss, and Let’s Conclude. The third stage comprised activities of Let’s Practice and Self-Reflection.
Students' misconceptions in algebraic concepts: A four-tier diagnostic test approach
Authors: Hestu Wilujeng  , Aristiawan  , Joel I. Alvarez
Published: February 2025

Misconceptions in algebraic thinking refer to misunderstandings in grasping and manipulating abstract concepts such as variables and mathematical relations. These misconceptions are often consistently applied by students in certain situations even though they deviate from the correct concept. This qualitative study used a case study approach focused on analyzing students' misconceptions in understanding algebra, specifically in the topic system of linear equations in two variables (SLETV). This study utilized a four-tier diagnostic test combined with the Certainty of Response Index (CRI) to identify students' misconceptions. The test consisted of 12 questions covering four aspects of algebraic thinking: problem-solving, mathematical modeling, generalization, and analytical thinking. The subjects were 118 junior high school students in Ponorogo who had studied SLETV materials. The results showed that students experienced misconceptions, such as errors in interpreting mathematical statements, simplifying concepts, and organizing ideas. Although their understanding was incorrect, the students exhibited a high level of confidence in their answers. Teachers should use more explicit approaches to convey abstract concepts and provide appropriate feedback. Diagnostic tools such as the CRI can help teachers identify students' misconceptions and offer more effective remedial teaching, thereby significantly enhancing students' understanding of algebra.

Authors: Makiling Rodillo , Christian G. Abalos  , Ma. Leah I. Abad  , Jomar C. Cabuquin
Published: February 2025

The successful passing of the Licensure Examination for Teachers (LET) by secondary education graduates is one of the core priorities of Tertiary Education Institutions (TEIs) in the Philippines, as they work to address the increasing demands of the teaching workforce and produce highly qualified educators. However, few studies have attempted to create a model to predict the probability of passing LET. In this study, a quantitative approach using a predictive-correlational design was used to analyze the correlations between areas of academic achievement and LET performance among Bachelor of Secondary Education (BSEd) graduates at a government-funded university in the Leyte province. This study also investigated the role of academic achievement in predicting BSEd graduates’ licensure examination performances. Using total enumeration sampling, 225 BSEd graduates’ academic achievement records and LET performances were considered. The results revealed significant correlations between the areas of academic achievement and licensure examination performance among BSEd graduates. Meanwhile, achievements in professional education courses followed by general education courses were the most significant predictors of LET performance. This result implies that BSEd graduates aiming to excel in LET should prioritize strong performance in their professional and general education courses during their studies, as it could significantly impact LET outcomes.

Published: February 2025

The importance of developing PISA-type questions and learning activities is to familiarize students with these questions. This study employs a research design with development studies that include the stages of preliminary evaluation and formative evaluation. This research was conducted in response to the low mathematical reasoning skills of students in Indonesia, focusing on eighth-grade junior high school students. Qualitative findings were obtained from field data in the form of interviews, photos, and videos of the activities. The results of this study produced six units of activity questions and three units of evaluation questions on the theme of elections, which are valid and practical for enhancing mathematical reasoning abilities of eighth-grade students. The average score of students for Activity 1, Activity 2, and evaluation questions reached 53.45, indicating the potential effect of PISA-type questions and activities in the context of uncertainty and data with the theme of elections on students' mathematical reasoning skills, which are categorized as adequate. The reasoning indicator that appeared most frequently was the ability to make a conjecture, while the ability to manipulate mathematics was rarely observed. Overall, PISA-type questions and activities in an election context can be used to strengthen students' mathematical reasoning abilities.

Mathematics can be found in cultural aspects. Moreover, Indonesia has a variety of cultures that can be explored and used as mathematics learning resources. Existing mathematics learning has yet to integrate cultural elements that are close to students. The aim of this study is to examine the findings of geometric objects and mathematics activities in the Moekhlas Sidik Red Mosque. The research method used was an ethnographic study and data collection techniques in the form of observations, documentation, and interviews. The obtained data were analyzed using an interactive model: data reduction, data presentation, data interpretation, and conclusion. This study found that the geometric objects include 2D shapes, 3D shapes, and geometric transformations. The 2D shapes observed are triangles, trapeziums, squares, rectangles, rhombuses, and semicircles. The 3D shapes that can be observed are rectangular prisms. Geometric transformation is the use of the principles of translation, reflection, and rotation. The mathematical activities that can be explored include creating tile patterns, finding the purpose of tile patterns, and drawing 2D shapes using geometric transformation principles. In addition, the existence of the Moekhlas Sidik Mosque provides socioeconomic value that has an impact on the surrounding community.
Enhancing fault tolerance in RDMA systems through hybrid protocol models
Authors: Santhosh Katragadda
Published: February 2025

Remote Direct Memory Access (RDMA) has become a critical technology in high-performance computing (HPC), cloud environments, and distributed systems due to its ability to provide low-latency, high-throughput data transfer by bypassing the operating system. However, ensuring fault tolerance in RDMA systems remains a significant challenge, particularly in scenarios involving network failures, node crashes, or memory corruption. This paper proposes a novel approach to enhancing fault tolerance in RDMA systems using hybrid protocol models. By combining the efficiency of RDMA protocols with the reliability mechanisms of traditional transport protocols (e.g., TCP/IP), the proposed hybrid model aims to minimize the performance impact of fault recovery while maintaining system resilience. We explore the design principles behind the hybrid protocol, outline its integration into existing RDMA systems, and present evaluation results comparing its performance and fault tolerance capabilities to existing methods. Our results demonstrate that hybrid protocols can significantly improve fault tolerance in RDMA networks with minimal degradation in performance, making them a promising solution for mission-critical applications requiring both high throughput and high reliability.

Published: February 2025

The level of polycyclic aromatic hydrocarbons (PAHs) and heavy metals (HMs) in surface water from Bakana River located within the hydrocarbon pollution-prone Niger Delta Region of Nigeria was assessed to evaluate possible human health hazards and other associated risk to seafood. Surface water samples were analyzed for various physicochemical parameters using standard analytical methods. The level of sixteen (16) USEPA-recognized PAH compounds and selected HMs (Zn, Cu, Ni, Pb, Cr and Cd) were investigated. PAHs and HMs were determined using gas chromatography-flame ionization detector (GC-FID) and atomic absorption spectrophotometer (AAS). Analytical results revealed deterioration of surface water from the study location, with significantly (P<0.05) high turbidity (30.00 ± 0.63 NTU), BOD (8.06 ± 0.66mg/l), total hardness (1079.05 ± 10.11mg/l) and nitrite (4.98 ± 0.16mg/l). For HMs, Cd and Pb showed values above WHO permissible limits, recording 0.014±0.001mg/l and 0.132±0.001mg/l respectively. Varying levels of PAH compounds were found to be present in the surface water samples. Naphthalene, acenaphthylene acenaphthene, phenanthrene, fluoranthene and pyrene showed significance presence when values were compared with results for control surface water samples. Health risk evaluation was performed using Estimated Daily Intake (EDI), Target Hazard Quotient (THQ) and Carcinogenic Risk (CR) assessment, and indicated that surface water from Bakana River has potential health risk cancer risk for Cd, Pb, Cr and Ni in adult and children populations. These findings demonstrate that residents of Bakana Community and its environs are exposed to contaminated surface water and the health risks associated with consumption of toxic contaminants in water.
Botnets and Critical Infrastructure Security: A Survey
Authors: Hallowe Andrew
Published: February 2025

Botnets have emerged as a significant threat to the security and resilience of critical infrastructure systems. These decentralized networks of compromised devices enable malicious actors to execute sophisticated cyberattacks, such as Distributed Denial of Service (DDoS) attacks, data exfiltration, and ransomware deployment, which can disrupt essential services and compromise national security. This paper examines the evolving landscape of botnet threats to critical infrastructure, highlighting the vulnerabilities inherent in increasingly interconnected systems, including industrial control systems (ICS), smart grids, and healthcare networks. It explores how advancements in artificial intelligence (AI), machine learning (ML), and the Internet of Things (IoT) have expanded the attack surface for botnets while also offering potential mitigation strategies. Furthermore, the paper reviews contemporary defense mechanisms, including anomaly detection, threat intelligence sharing, and network segmentation, and assesses their efficacy in safeguarding critical infrastructure. By identifying gaps in existing security frameworks and proposing a multi-layered, proactive defense approach, this study aims to enhance the resilience of critical infrastructure against botnet-driven threats. The findings underscore the urgent need for collaboration between policymakers, industry stakeholders, and cybersecurity experts to develop robust and adaptive solutions in the face of this escalating cyber threat.

In aquaculture, probiotics appear as one of the alternatives to the excessive use of antibiotics. They promote good health, growth and improve the quality of fish culture water. One route of administration is incorporation into foods. But the mode of incorporation influences their viability and density. The objective of this study is to evaluate the effectiveness of incorporation of Saccharomyces cerevisiae and Bacillus subtilis by spraying with three binding agents (sterile salt water 0.9 %, vegetable oil and egg white). After determining the type of interaction existing between the two probiotics, 3×109 CFU of each of them was sprayed onto 30 g of granules. Then, the viability of the incorporated probiotics was evaluated over 12 days and after 60 minutes of residence in water. The density of incorporated probiotics showed a significant difference with vegetable oil in S. cerevisiae for an average of 3.28×107 CFU/g. This density varies from 1.5×106 to 2.75×106 CFU/g with B. subtilis among all binders. For the viability of 12 days, we observe a progressive increase in microbial density with salt water as a binder in B. subtilis from 2.4×104 to 5.35×106 CFU/g and S. cerevisiae of 7.43×106 to 1.5×107 CFU/g. The contact test on water with B. subtilis shows a decrease in microbial density from 3.5×106 to 1.56×106 CFU/g, while with S. cerevisiae it favors an increase from 3.07×107 to 4, 56×108 CFU/g with all binding agents. Sterile salt water 0.9% is the appropriate binding agent for both probiotic strains.

The aim of this study was to determine the prevalence of antibiotic resistance among Gram-negative bacilli on livestock farms. A total of 356 faecal samples from farms in 9 cities across 6 provinces were collected. Isolates obtained after culture and isolation were identified using the API 20E gallery. Following culture, 51.4% of the samples yielded colonies. Identifications revealed Escherichia (30.0%), followed by Pseudomonas (26.2%), Serratia (17.5%), and Enterobacter (6.56%), among others. Antibiotic susceptibility testing was conducted using the disc diffusion method. Susceptibility tests indicated resistance to Ampicillin (68.3%), Amoxicillin + Clavulanic Acid (66.7%), Cefotaxime (65.6%), Cefepime (60.1%), Aztreonam (59%), and Ertapenem (49.2%). Maximum resistance to Ceftazidime (77.0%) was observed, particularly in Escherichia, Pseudomonas, Serratia, and Enterobacter, posing a public health problem and a threat to the health of these Populations. All identified isolates exhibited antibiotic resistance at least to three or more antimicrobial family of antibiotics, and were multidrug resistance (MDR) bacteria. Some of them are associated with ESβL (7.1%). Given that MDR bacteria were isolate from farm animals that are intended for human consumption, there is a significant risk of transmitting MDR strains to consumers, posing a substantial threat to human health.
