Authors: Durazo Armenta Arturo Alberto , Martínez Gálvez Berenize Olivia , López Valenzuela José Jesús
Published: February 2025

Se analiza la importancia del control interno en las organizaciones sindicales, reformas legislativas recientes que han transformado su funcionamiento. Desde 2012, la Ley Federal del Trabajo exige acceso a la información pública para los sindicatos, y desde 2014, el artículo 6º de la Constitución los clasifica como sujetos obligados a rendir cuentas. El estudio se centra en la implementación de normas de control interno en un sindicato específico, alineadas con las Normas de Información Financiera Mexicanas, debido a la gestión de recursos públicos, cuotas sindicales y presupuestos anuales; todo ello a través de la implementación de un Manual de Políticas y Procedimientos. Se usaron métodos descriptivos, inductivos y analíticos para subrayar la relevancia del control interno en la prevención y detección de riesgos y fraudes. Se revisaron documentos financieros, se realizaron entrevistas con directivos y se encuestó a miembros sobre la transparencia y eficiencia en la gestión. Los hallazgos muestran que un control interno robusto mejora la transparencia financiera y la eficiencia operativa en los sindicatos, aunque se identificaron áreas para mejorar, como la capacitación del personal y el uso de tecnología en el monitoreo. Se concluye que el control interno es fundamental para mantener la integridad financiera y fortalecer la confianza de los miembros, recomendando políticas adaptadas y formación continua del personal.

Modeling Nonlinear Signal Components Based on Volterra Series in the Frequency Domain during Spectral Reconstruction
Authors: Perets K. , Lysechko V. , Komar O.
Published: February 2025

The article presents a study on the application of Volterra series for modeling nonlinear signal components in the frequency domain. The proposed spectral reconstruction algorithm accounts for the impact of signal nonlinearity on its frequency-time distribution. Volterra series enable the extraction of nonlinear components in the frequency spectrum, improve the accuracy of signal reconstruction, and optimize filtering in complex radio environments. Experimental calculations demonstrated the algorithm's effectiveness in reducing mean-square error (MSE) and mean-square deviation (MSD) by up to 20,55% compared to lower-order models. The algorithm showed the ability to preserve the accuracy of signal amplitude characteristics by 10,3% better than first-order models and to ensure more precise phase reproduction with a 5,2% improvement. In dynamic radio environments, the algorithm significantly reduced the impact of inter-channel and inter-symbol interference, enhancing signal robustness. Specifically, at key time points, the second-order model reduced MSE by an average of 43,6–57,8% compared to the first-order model. The prospects for further research include the development of the algorithm for multichannel communication systems, integration of machine learning methods for dynamic parameter tuning during reconstruction, and the expansion of its application in cognitive radio networks with highly variable environments

This study explored spatial patterns of overflights at Denali National Park and Preserve. Data were collected at Old Town Cantwell, Healy Radio Repeater, and K?esugi Ken Ranger Station. In total, overflights were analyzed from September 18th, 2021 to October 6th, 2022 (384 total days; 56 days of missing data) and May 25th, 2023 to September 13th, 2023 (112 total days; 0 days of missing data) using Automatic Dependent Surveillance-Broadcast (ADS-B) data. Phase 1 of the analysis focused on all overflights and revealed the transportation network of overflights above DENA. Phase 2 of analysis focused on low-level overflights that fly at or below 21,000 feet above mean sea level (MSL) and flew within 10 miles of the DENA boundary and found that the majority of waypoints were below 12,000 feet MSL. Phase 3 of analysis removed all overflights that were government flights, major airlines, and survey flights. The remaining flights were low-level overflights predominantly air tours. Kernel density analysis was conducted using waypoints segmented into 500 feet above ground level (AGL) altitude intervals. The altitude interval with the highest density of overflights was ?0?500 feet AGL?. This information can be used for planning and management purposes and this study serves as a resource for future research that intends to use more advanced analytics.

On the Evolution of Random Integer Compositions
Authors: Bevan David , Threlfall Dan
Published: February 2025

We explore how the asymptotic structure of a random $n$-term weak integer composition of $m$ evolves, as $m$ increases from zero. The primary focus is on establishing thresholds for the appearance and disappearance of substructures. These include the longest and shortest runs of zero terms or of nonzero terms, longest increasing runs, longest runs of equal terms, largest squares (runs of $k$ terms each equal to $k$), as well as a wide variety of other patterns. Of particular note is the dichotomy between the appearance and disappearance of exact consecutive patterns, with smaller patterns appearing before larger ones, whereas longer patterns disappear before shorter ones.

Authors: Alazaidah Raed
Published: February 2025

The predictive performance of any classification or regression model highly depends on the quality of the collected data. Most of time datasets suffer from the problem of missing values, and hence, several techniques have been proposed to handle the problem of missing values. Consequently, this paper aims to quickly survey the most well-known techniques that handle missing data, and identify the best one to use concerning several issues such as the ratio of missing values, type of attributes in the dataset, number of instances, and number of class labels. Hence, seven different and well-known missing values handling techniques have been evaluated and compared using five datasets with different characteristics concerning the Accuracy metric. The results revealed that the K- Means technique is the most appropriate technique to handle the problem of missing data and the SMO classifier is the best choice to use as a classification model in case of missing data.

Published: February 2025

This study examines the Benin public's perceptions of media framing gender equality in Nigeria and its impact on national development. The study's rationale was to ascertain how media framing practices shape public attitudes and influence policy responses, ultimately affecting the overall advancement of gender equality in Nigeria. Anchored on framing theory, the study employed the survey research design and collected data using a structured questionnaire from 384 respondents in Benin City using the multistage sampling technique. The data were presented in tables and analyzed using frequency counts, straightforward percentages, and mean scores. Findings revealed that the media create awareness of gender equality among the Benin public to a great extent, with social media identified as the most effective platform. Also, the standard frames employed by the media on gender equality issues are social justice and political empowerment frames. However, despite recognizing the media’s effectiveness, concerns about bias and fairness persist. The researchers conclude that while media plays a significant role in raising awareness, there is considerable skepticism regarding the accuracy and bias of these portrayals. Recommendations include efforts that should be made to increase the frequency and consistency of gender equality content across all media platforms, including traditional and digital media, among others.

Gaze cues facilitate incidental learning in children aged 7–10 years, but arrow cues do not
Authors: Ishikawa Mitsuhiko , Yoshioka Ayumi
Published: February 2025

From infancy, humans use gaze cues from others to learn about their surrounding environment. It is known that gaze cues facilitate the cognitive processing of targets in both infants and adults, but what developmental changes occur during childhood? This study investigated the impact of gaze cueing on incidental learning in children aged 7–10 years (n = 80). Participants completed a cueing task where they were presented with gaze or arrow cues (valid or invalid) followed by a target stimulus. Then, participants conducted an incidental memory test including the target stimuli presented in the cueing task and novel stimuli. Results revealed that valid gaze cues significantly enhanced memory performance compared to arrow cues, while gaze cues and arrow cues had similar effects on attention orienting. This effect was consistent across age groups, suggesting that gaze cueing facilitates memory regardless of developmental stage. The findings support the socio-communicative aspect of gaze cues, which may influence cognitive facilitation in joint attentional situations in childhood. Joint attentional situations may be rewarding, influencing the motivation for implicit cognitive processing of objects that are the focus of attention. This study contributes to our understanding of spontaneous social cognition in children and underscores the importance of gaze cues in facilitating memory and learning in social contexts.

Authors: Batista Josiane A D , de Oliveira Rayane M , Lima Carlos H M , Lana Júnior Milton L , dos Anjos Virgílio C , Bell Maria J V , Rocha Márcio S
Published: February 2025

We use optical tweezers and atomic force microscopy to investigate the potential of rare earth elements to be used as anticancer agents in the development of new chemotherapeutic drugs by characterizing the binding of three rare earths (ytterbium, neodymium, and erbium) to double-stranded DNA, which is one of the main targets for these drugs inside cells. The three elements presented a significant interaction with the biopolymer in buffers of physiological relevance, typically binding with very high equilibrium association constants (106 to 107 M−1) at the DNA grooves. Furthermore, neodymium and erbium can also induce a very strong compaction/condensation of the double helix at high concentrations, promoting DNA collapse at the single molecule level in a similar way to what occurs with classical DNA condensing agents such as polycations and depletants.

Anomalous Neutral Hydrogen Column Densities in Local Interstellar Medium Clouds*
Authors: Linsky Jeffrey L. , Redfield Seth
Published: February 2025

Analysis of high-resolution spectra of the hydrogen and deuterium Lyα lines provides measurements of interstellar neutral hydrogen column densities N(H i) to 113 stars within 50 pc of the Sun. Plots of N(H i) versus distance through the LIC, G, Mic, and other clouds in the local interstellar medium (LISM) show very interesting properties. For the LIC and G clouds, nearly all of the observed neutral hydrogen occurs within 3 or 4 pc of the Sun with no significant additional neutral hydrogen at larger distances out to 50 pc, except for several sight lines with anomalously high N(H i). Scatter about the mean hydrogen column density in the LIC is several times larger than the measurement errors. We evaluate several possible sources of the high N(H i) sight lines. Seven sight lines with anomalously high N(H i) are aligned perpendicular to the line connecting the centers of the LIC and G clouds where the two clouds merge creating a mixed cloud region. The high N(H i) in these seven sight lines can be explained by their paths through an irregularly shaped mixed cloud region where the neutral hydrogen number density is the sum for both clouds. However, the most recent nearby supernova explosion created a shell that is seen in nearly the same direction perpendicular to the LIC/G axis and may also explain these seven high N(H i) sight lines. Other possible explanations for the high N(H i) sight lines include interstellar shocks, wakes produced by stars moving rapidly through the LISM, and regions where other clouds may overlap.
Observations of the X-Ray Millihertz Quasiperiodic Oscillations in Hercules X-1
Authors: Yang Wen , Wang Wei
Published: February 2025

With a systematic timing investigation of the persistent X-ray binary pulsar Her X-1 based on a large number of Insight-HXMT observations between 2017 and 2019, we confirm the presence of X-ray millihertz quasiperiodic oscillations (mHz QPOs) at ∼0.01 Hz. By applying wavelet analysis in our data analysis procedures, we first identify ∼0.005–0.009 Hz QPOs coexisting with the ∼0.01 Hz QPOs. Wavelet analysis suggests that these QPO features show transient behaviors, that the frequencies of mHz QPOs evolve in short timescales. There exists a positive relation between QPO centroid frequency (from ∼0.005 to 0.009 Hz) and X-ray luminosity, while the 10 mHz QPO frequencies remain nearly constant for different luminosities, which suggests different physical mechanisms for the two types of mHz QPOs. The 10 mHz QPOs in both X-ray and UV bands would have the same origin related to the beat frequency where the Alfvén radius is close to the corotation radius, and the 5 mHz QPOs may originate from magnetic disk precession.
Dynamics of monoatomic steps on the Si(100) surface during MBE growth and post-growth annealing

The dynamics of monoatomic steps on the Si(100) vicinal surface during molecular beam epitaxy (MBE) growth and annealing is studied based on the analysis of reflection high-energy electron diffraction intensity variations. During growth, the initially equally spaced A- and B-steps are getting closer: the width of the A-terraces decreases to a certain minimum value, which increases with increasing growth temperature. The number of Si monolayers deposited until the minimum distance between the A- and B steps is reached increases monotonically with increasing temperature.

After interrupting the Si deposition flux (during annealing) the width of the A-terrace gradually increases to the initial value. The time of such relaxation to the initial configuration of the steps decreases with increasing temperature and increasing miscut angle. The observed behavior of the steps during annealing is in good agreement with the available theoretical models of the step dynamics and is explained by the presence of an exchange flux of Si atoms between the A- and B-steps due to the elastic interaction of the steps caused by the anisotropy of the elastic stress tensor on the reconstructed Si(100) surface. However, the available models fail to explain the experimentally observed monotonically increasing temperature dependence of the number of Si monolayers deposited until the steps approach each other during growth, which indicates the need to modify the model of incorporation of Si adatoms into steps in the case of high temperatures.
Lorca según Cernuda: sobre «A un poeta muerto (F. G. L.)»
Authors: Insausti Gabriel
Published: February 2025

Un análisis de «A un poeta muerto (F. G. L.)» que sin renunciar a la lectura atenta preste atención al contexto permite advertir que Cernuda elabora allí una determinada imagen de Lorca mediante la selección de unos rasgos; que esta selección posee un sentido muy determinado dentro de la disputa con Dámaso Alonso y otros amigos de Lorca; que en ese Lorca, el Lorca según Cernuda, habría un espejo del propio Cernuda; y que esa imagen cumple una función y contiene un pronunciamiento dentro de las polémicas literarias y políticas de la Valencia de 1937 en que se escribió y publicó.
La voz al mito debida: reescritura y desmitificación de la mitología y la épica clásicas en el ciclo troyano de Luis Alberto de Cuenca
Authors: Martín Barrachina Antonio
Published: February 2025

Cumplido el medio siglo, la obra de Luis Alberto de Cuenca destaca como uno de los testimonios más valiosos de la poesía hispánica actual. De la multiplicidad de facetas y registros que conforman su poética, la presencia de la tradición clásica constituye una de sus constantes. El artículo analiza la reescritura y desmitificación de la mitología y la épica clásicas en los poemas «El juicio de Paris», «Nausícaa», «Helena: palinodia» y «Teichoscopia». En ellos, la temática y los procedimientos empleados conforman un particular ciclo troyano en la poesía del autor. En el diálogo de la mitología con el mundo contemporáneo, la reescritura desmitificadora se evidencia como justificación de la necesidad del mito.
Préstamos del catalán en el castellano oriental del siglo XV: el papel de las tipologías textuales
Authors: Raab Matthias
Published: February 2025

El estudio abarca las transferencias léxicas del catalán que se documentan en textos del siglo XV escritos en variedades orientales del castellano. El análisis multifactorial incluye cuestiones cronológicas, tipológicas, etimológicas, morfológicas, gramaticales y semánticas e investiga la presencia de numerosas variantes léxicas. La mayoría de catalanismos léxicos son tecnicismos y se documentan en textos científicos y técnicos, sobre todo en traducciones del catalán, mientras que los textos jurídicos y administrativos recogen un mayor número de elementos gramaticales procedentes de la lengua catalana.

Published: February 2025

The education of motor conducts offers an essential paradigm shift for the present and future physical sports educator, in line with the challenges posed by the Sustainable Development Goals of the 2030 Agenda. The teacher, monitor, animator, or coach must work on the integral development of each person in a motor game, promoting not only physical skills, but also emotional, social, and cognitive aspects. This chapter presents a pedagogical intervention designed to train university students in the field of physical activity and sport in the education of motor conduct through the practice of motor games. Through experimental work in the classroom, students collected, analysed, and discussed the impact of motor games on the dimensions of motor conduct, favouring the transfer of this knowledge to future educational contexts. to future educational contexts.
Use of Pedagogical Interventions to Improve Well-Being in Physical Education
Authors: Pla-Pla Paula , Lavega-Burgués Pere , de Ocáriz Unai Sáez
Published: February 2025

Living in society requires establishing social relationships, which often lead to disagreements and conflicts. To promote well-being among secondary school students, a quasi-experimental study evaluated two pedagogical interventions. Using a pre-post-test design, data were collected from four natural groups: two engaged in a Motor Conduct Education focused on socio-affective skills, while the other two followed a Sport Education approach lacking social interaction emphasis. The results indicated significant improvements in conflict management and positive emotional intensity among participants in the Motor Conduct Education group, particularly benefiting females in emotional stability and males in conflict perception. These findings suggest that integrating socio-affective education effectively enhances both emotional well-being and conflict resolution skills in secondary school students.
Inclusive, Sustainable Motor Play for People With Intellectual Disabilities

The document describes a university project focused on inclusive and sustainable physical education (PE) for individuals with intellectual disabilities (ID). Through a service-learning (SL) approach, students designed motor games using recycled materials, promoting physical activity, inclusion, and sustainability. The project combined theoretical learning with practical experiences, involving direct interaction with athletes with ID. It emphasized the importance of sustainable, inclusive PE in teacher training and highlighted the need for future educators to develop skills in diversity and adaptive PE.
Philosophical Approaches to Qualitative Research (Positivism, Phenomenological Approach & Critical Social Sciences)
Authors: Kaluarachchi K. A. D. P.
Published: February 2025

This article delves into the philosophical underpinnings and methodological frameworks of positivism, phenomenology and critical sociology as they apply to the study of human behaviour within the social sciences. Originating from distinct historical contexts, these approaches offer contrasting perspectives on knowledge construction and interpretation. Positivism rooted in empirical observation and the scientific method seeks to uncover universal laws governing human behavior through systematic data collection and analysis. In contrast, phenomenology emphasizes the subjective experiences and meanings individuals attribute to their social interactions advocating for an inductive approach that prioritizes understanding over explanation. Critical sociology, drawing from critical theory critiques positivist and phenomenological approaches for their perceived limitations in addressing power dynamics, social inequalities and the complexities of social structures. This synthesizes these perspectives, highlighting their contributions and limitations in advancing the understanding of human behavior and societal dynamics. It underscores the importance of adopting multiple methodological approaches in sociology to enrich our comprehension of diverse social phenomena and to foster a more inclusive and critical examination of social reality.
Film Review of 'Margarita with a Straw'- Exploration of Sexuality by a Woman with Disability
Authors: Jayasena C. , Singh N.
Published: February 2025

Cinema is a tool for positive social change within social work. It is a powerful tool for challenging deeply rooted social stereotypes in society. Cinema would provide a robust and in-depth portrayal of the lives of women with disabilities who are subject to double and triple oppression. Especially in dominant discourses, social models often interpret phenomena such as disability and femininity through narratives of pity, past karma, and social discrimination. The profession of social work aims to create well-being for marginalized citizens whose rights are violated in everyday life. In disability and social work, media, such as cinema, could critically analyze social models of women with disabilities. This review examines disability representation, focusing on Shonali Bose's 2014 film Margarita with a Straw, which explores the sexuality and intimacy of a young woman with disabilities. The film is relevant to a country like Sri Lanka in the South Asian region. Indian cinema has often highlighted the struggles and resilience of people with disabilities in their daily lives. Themes such as sexuality, intimacy, love, and relationships have been explored to a limited extent, especially in Hindi films. These dimensions of human life, often neglected in the South Asian region itself, must be addressed. The review uses content analysis to explore cinema as a medium. Finally, the film emphasizes the potential of films as social work tools for women with disabilities and also as tools for advocating for their rights and visibility.
