Emergent communication in simulated robotics: supporting supply chains through evolutionary computation
type: item
description: This study introduces an innovative model of cooperation and communication among a collective of Marxbot robots. The primary task involves the retrieval and deposition of raw materials onto a processing band, as well as the collection and placement of finished products onto a packaging band. The robots are controlled using artificial neural networks (ANN), which are optimized using a genetic algorithm (GA) within the framework for autonomous robotics simulation and analysis (FARSA) environment. Our simulations have demonstrated that homogeneous robot groups utilizing emergent communication via light emitting diodes (LED) significantly outperform those with predefined signal systems or no communication capabilities. The superior performance is attributed to the organizational structure that arises from signal emergence within the group dynamics and environmental interactions. These findings emphasize the relevance of evolutionary robotics (ER) principles in meeting the demands of Industry 4.0.

Primary school teachers in Tlaxcala, Mexico: their trajectory in the face of gender inequalities
type: item
description: From theoretical and methodological approaches, female professional development in education is one of the many reflections of social inequality which leads to reflect on female schoolteachers’ professional and personal experience from a gender view. The objective of this article is to analyze female schoolteachers career paths in Tlaxcala, in an inequality framework. To achieve this, an instrument with four dimensions was designed: sociodemographic data, initial and continuing education, labor mobility, and gender violence. Results identify, in the professional field, lower labor mobility due to their academic and continuing training. In the personal field, they are affected by aspects such as marriage, maternity, patriarchal culture, and gender violence victimization.

¿Who is more aggressive? An analysis of hostility in medical students and its expression by gender
type: item
description: This quantitative, cross-sectional, and comparative study analyzed aggression levels among 638 medical students at a public university in Nayarit (59.2 % female; 40.8 % male) using the Buss-Durkee Hostility Inventory (BDHI). Due to the non-normal distribution of the data, Spearman and Kruskal-Wallis tests were employed for statistical analysis. The results revealed significant gender differences (p < 0.05): while men scored higher in physical aggression, women presented superior levels in verbal aggression, indirect aggression, irritability, guilt, and overall hostility scores. Furthermore, a moderate correlation between resentment and guilt was identified across both sexes. These findings challenge the traditional conception of aggression as a predominantly male trait, suggesting that within the medical academic context, women manifest higher levels of hostility in relational and verbal dimensions. This highlights the critical need for preventive interventions incorporating a gender-sensitive approach.

Personalized physical activity in people with disabilities: a scoping review of empirical evidence
type: item
description: People with disabilities face physical, social, and structural barriers that restrict participation in physical activity programs and negatively affect health and quality of life. This study aimed to examine recent empirical evidence on the benefits and challenges of personalized physical activity interventions for this population. A scoping review was conducted in PubMed, Scopus, and Web of Science following PRISMA-ScR guidelines. Empirical studies published between 2017 and 2025 in English and Spanish were included and selected using PICOS criteria. Eleven studies addressing different types of disabilities were identified. Reported benefits included improvements in strength, balance, mobility, autonomy, social inclusion, and quality of life. Recurrent challenges involved shortages of trained personnel, limited accessible infrastructure, and economic sustainability constraints. Current evidence supports the effectiveness of personalized physical activity programs; however, persistent structural barriers and methodological gaps highlight the need for future research and intersectoral policies to ensure equitable and sustainable implementation.

Experimental study of a water source heat pump (WSHP): evaluation of R32 refrigerant as a direct replacement for R410A
type: item
description: The energy performance of a water-source heat pump in heating mode was experimentally evaluated using R32 as a direct replacement for R410A. For this purpose, an experimental bench was constructed to simulate the operating conditions of the water source (water-glycol mixture) flow rate and temperature, as well as the set-point condition (space-heating temperature). These conditions expand on the existing literature, positioning R32 as a viable option in the short- and medium-term. The results indicated that R32 outperformed R410A, achieving COP increases of up to 40%. For set-point temperatures of 31 °C and 28 °C, the pump achieved 37% energy savings with R32 compared to R410A. Finally, a TEWI analysis was performed, where R32 showed an 84.2% reduction in indirect emissions due to lower energy consumption.

Impact of tourism on gender relations in the Magical Town of Tapijulapa
type: item
description: This research was carried out in Villa Tapijulapa, located in the municipality of Tacotalpa, Tabasco, Mexico. It shows the impact of tourism on gender relations of tourism service providers; additionally, it seeks to describe the roles established for genders in their families. This work was developed adopting a qualitative methodology, where semi-structured interviews were applied to 12 men and women (25 and 68 years old) involved in tourism activities. It was found that gender roles assigning specific functions to men and women persist; for instance, women carry out work activities and, at the same time, must take care of their homes. Women are more involved in cooking and hosting, while men work in jobs that require greater physical strength, leadership, or dissemination of art and culture.

Perspectives for the use of entomopathogenic fungi for pest control in chili crops
type: item
description: Entomopathogenic fungi (EPF) are used to control pests as an alternative to chemical pesticides. The aim was to determine producers' knowledge and attitude toward the potential use of EFF against pests in the chili crop in the Sotavento region of Veracruz. A semi-structured questionnaire was applied to 22 chili producers, selected using the “snowball” technique, and their attitude toward the use of EPF in social, economic, and environmental aspects was measured using a Likert scale. Twenty-seven percent of interviewees know about EPF, and 18% use Beauveria bassiana and Metarhizium anisopliae against chili pests. Producers expressed a positive attitude toward social and environmental aspects. The heterogeneity in knowledge, use, and attitude within a given territory are essential elements to consider when promoting the use of EPF and reducing dependence on chemical pesticides.

Discursive disputes on Mexico's Energy Reform: symbolic power and the legitimation of sustainable development models
type: item
description: This article analyzes discursive disputes surrounding Mexico’s 2013 Energy Reform through comparative critical discourse analysis (CDA). A corpus of legal texts and newspaper articles was examined. The objective was to identify ideological dimensions that structure meanings about energy, development, and sustainability. Using standard CDA procedures, comparable discursive categories were constructed. Results show clear divergences: legal texts legitimize the model through technocratic frames, whereas the press deploys counter-narratives with a socio-environmental emphasis. It is concluded that discourse not only accompanies the reform and its secondary laws, but it also configures them symbolically. The study contributes with evidence from the Global South on the influence of language in the legitimacy of energy policy.

Factors influencing the willingness to recommend a sun and beach destination in the northwestern region of Mexico: an econometric evaluation
type: item
description: The objective was to analyze the factors that influence the willingness to recommend a sun and beach destination in northwestern Mexico. The methodology was quantitative, with a survey administered to a sample of 516 tourists during April 2023. The theoretical approach of random utility maximization was used. The dimensions of analysis, whose values were ranked from excellent to poor, were obtained from the principal components and included in the Logit and Probit models. The results show three main components: 1) sustainability, where the probability of recommending the place decreases by 2.06%; 2) services, where the probability of recommending decreases by 2.21%; and 3) competitiveness, where the willingness to recommend decreases with a probability of 2.32%. The relevance of this work lies in its contribution to decision-making aimed at strengthening the destination's sustainability, competitiveness, and loyalty strategies.

Analysis of physical properties in three mango varieties processed with indirect solar and electric drying
type: item
description: Mexico is one of the leading exporters of mangoes but faces post-harvest losses of up to 40%. This study evaluated the effect of indirect tunnel solar drying and non-convective electric oven drying on the physical and colorimetric properties of Manila, Ataulfo, and Oro mangoes. Moisture content, weight loss, water activity, and CIE-Lab parameters (L*, a*, b*) were analyzed. Both methods reduced moisture content to below 8%, inhibiting microbial growth. However, differences in color were observed: all samples showed a decrease in yellowness (b*) and an increase in redness (a*), which were more intense in the electric oven. Indirect solar drying better preserves brightness and yellow-orange tones. The Oro variety showed the greatest color variation (∆E > 40), possibly due to its rich composition of sugars and polyphenols. These results support solar drying as a sustainable alternative for mango preservation.

Comparative analysis of welding processes using MCDM methods for the development of a component joining station
type: item
description: Welding methods are common in production lines, which allows to join components with various properties that can impact quality, safety, and performance. There are techniques such as electric arc, induction, gas, GTAW, and GMAW, whose selection depends on the characteristics and needs of the process, which can be complex due to the multiple requirements to be met. This paper aimed to identify attributes of welding methods so as to weigh alternatives and, through a multi-criteria decision-making method, choose the most appropriate technology for a specific process. In particular, the AHP was used to weigh attributes found in the literature, and the TOPSIS method was applied to select the welding alternatives. At the end of the manuscript, the selection that best fitted the requirements of the joining station is provided.

Ludoeducational computing for the revitalization of Nahuatl: design and evaluation of an interactive tool for primary school children
type: item
description: This article presents the design, implementation, and evaluation of a ludic-educational platform for learning Nahuatl among elementary school children. The tool integrates an educational game and an automatic translator, combining intelligent computing, didactics, and game science to provide a personalized learning experience. It was implemented in a Mexican primary school in the state of Hidalgo, where improvements in language learning and high usability were observed, achieving a score of 84.7 on the System Usability Scale. These results demonstrate that ludic-educational computing is an effective strategy to enhance language learning and contribute to the preservation of cultural identity. Additionally, areas for improvement were identified, such as visual design and the inclusion of more multimedia resources. The tool is proposed as a replicable model for other endangered languages.

Factors contributing to students’ implicit and explicit learning difficulty of targeted English grammatical structures
type: item
description: This is an exploratory, correlational research and represents a conceptual replication of R. Ellis’ (2006) study. The purpose of this inquiry was to examine 17 grammatical structures in terms of learners’ explicit and implicit learning difficulty. Thirty-three students enrolled in a BA in an ELT program in Mexico at three different levels of proficiency (A1 to B1) were recruited. The following instruments were used to measure implicit and explicit knowledge: an oral elicited imitation test, a timed grammaticality judgement test, an untimed grammaticality judgment test, and a metalinguistic knowledge test. Results showed that students performed better on the explicit tests than on the implicit tests; besides this, there was a non-significant and very weak correlation (rho = -0.18, p = NS) between the two sets of mean scores.

Didactics of forms and algebraic procedures in the teaching of differential and integral calculus
type: item
description: In high school differential calculus courses, many students struggle to differentiate functions and to choose and combine the correct formulas, especially for products and fractional exponents. A literature review of widely used calculus textbooks examined how these topics are presented. In addition, an exploratory study with focus groups at CBTis 190 investigated the reasons for students’ initial difficulties. Based on these findings, we designed a teaching proposal for using formula sheets that includes the algebraic steps needed in differentiation and connects this work to integral calculus. The proposal emphasizes selecting key rules (product, power, and chain) and organizing the formula sheet to support clear, step-by-step decisions while differentiating. After the intervention, a follow-up assessment showed a notable improvement, particularly among students who initially scored low on the diagnostic test.

Adaptogens: nature, function, and main representatives
type: item
description: Adaptogens are natural compounds, primarily of plant origin, that have attracted growing scientific interest due to their ability to enhance the body's nonspecific resistance to physical, mental, and environmental stress. They act by modulating the hypothalamic-pituitary-adrenal (HPA) axis and other neuroendocrine systems, promoting homeostasis without altering normal physiological functions. Recent research has documented beneficial effects of adaptogens such as Panax ginseng, Rhodiola rosea, and Withania somnifera in reducing stress, fatigue, and mood disorders, as well as in improving physical and cognitive performance. Despite empirical support from preclinical and clinical studies, challenges remain regarding the standardization of extracts, specific molecular mechanisms, and large-scale clinical validation. This paper reviews the most recent evidence on major adaptogens, their mechanisms of action, therapeutic applications, and future perspectives.

Productive diversification of small orange producers in two municipalities of Huasteca Potosina, Mexico
type: item
description: This study analyzes the productive diversification of small-scale orange producers in Tampacán (G1) and Axtla de Terrazas (G2), Huasteca Potosina, Mexico. Area, diversification, and productive profile were evaluated through interviews with 54 producers and nonparametric analyses (Kruskal-Wallis, chi-square, and Spearman's correlation). Producers own an average of 3 ha, allocating 2 ha to orange cultivation in hilly areas. Age was different (p < 0.05) between group 1 (G1, 58 years) and group 2 (G2, 42 years). 25% of G1 and 37.5% of G2 have diversified production: G1 focuses on staple crops, while G2 cultivates citrus, sugarcane, and coffee. A negative correlation was found between orange acreage and diversification index (rho = -0.287, p = 0.036). Producers with larger orange acreages reported less diversification. Implementing comprehensive strategies that consider productive diversification will contribute to improving orange production.

Validation of the brief resilience scale in adolescents and its mediating role between indirect violence, PTSD, and substance use
type: item
description: Resilience is a dynamic personality characteristic that enables adaptation in the face of adversity. There is substantial scientific evidence demonstrating its association with mental health, highlighting the importance of its study and measurement. The brief resilience scale (EBRA-14) is one of the most widely used instruments internationally. Therefore, the aim of this study was to obtain evidence of the validity and reliability of the EBRA-14, as well as to evaluate its mediating role between exposure to indirect violence, post-traumatic stress disorder symptoms, and substance use. A questionnaire was administered to 744 upper-secondary students in Guadalajara, Jalisco, Mexico. Results showed adequate levels of validity and reliability in the two factors of the scale, with eight items grouped into two dimensions, consistent with the original version. Furthermore, resilience was confirmed to mitigate the negative impact of exposure to violence on substance use.

Theoretical reflections and hypotheses of circular economy for waste reduction
type: item
description: In the face of rapidly increasing waste, circular economy (CE) represents an alternative that can transform production and consumption processes. However, despite the rise of CE, there is no conceptual and theoretical clarity. This work aims to identify and clarify the economic theory behind CE; generate a CE model; and propose economic, environmental, and social hypotheses that can be tested in subsequent research. The methodology used was a critical literature review based on the snowball method, through which 143 articles were reviewed using a scientific article search engine. Results included the identification of three basic economic models along with their limitations for correct interpretation; the generation of a CE model; and the proposal of new hypotheses and indicators that can be tested in subsequent studies.

Towards the automation of attendance control: improving administrative efficiency in higher education in Ecuador
type: item
description: Attendance control for teachers is a crucial component in the educational system, but it is facing significant challenges due to manual methods that generate errors and waste time. The implementation of technologies, such as biometric systems and human resource management tools, presents an effective solution to optimize this process. Information and communication technologies (ICT) allow for more precise monitoring of performance, improving efficiency and decision-making. However, resistance to change and a lack of technical expertise are both obstacles that must be overcome. Automation not only enhances human talent management, it also contributes to a more effective and sustainable educational environment. Continuous evaluation of the impact of these technologies is essential to ensure educational quality and continuous improvement.

Marital subsystem and psychosocial factors in therapeutic adherence in patients with diabetes of the Veracruz Naval Specialty Hospital
type: item
description: The aim is to associate marital dysfunction and treatment adherence in patients with type 2 diabetes mellitus (DM2). The study was developed with adults of both sexes, people over 18 years old, who attended the service of the Naval Specialty Hospital in Veracruz. Four instruments were used: the Chávez Aguilar marital subsystem functionality scale, the family APGAR, the Morisky-Green test, and the AMAI 2022 questionnaire. A total of 186 patients were evaluated, predominantly women (60.2%), aged 51 to 60 (60.8%). Most participants were relatives of military personnel (82.2%), and 50% of the total population were obese. Only 18.8% were adherent to treatment, with a higher proportion of men than women (65.7% and 34.3%). Marital dysfunction was associated with non-adherence to treatment in patients with DM2 (OR = 25.27, p < 0.001). Smoking and marital dysfunction showed a positive association with adherence (p < 0.001).

Psychometric analysis of the Feminism and Women’s Movement Scale in cisgender LGB youth from Lima, Peru
type: item
description: Attitudes regarding feminism and women's movements have gained relevance in cisgender LGB youth, although there are still few validated instruments to assess these attitudes. The purpose of the research was to carry out the validation of the psychometric properties of the Feminism and Women's Movement (FWM) Scale in the cisgender LGB community, an instrument designed to measure attitudes towards feminism. It was conducted under an instrumental design, which allows evaluating the potential and reliability of psychometric instruments. The population studied was composed of members of the cisgender LGB community, achieved using the snowball sampling technique, which facilitated the inclusion of those who had relevant experiences. It was found that the FWM possesses a unidimensional structure with acceptable indicators of fit, is reliable, and has relationship to flourishing.

Temporal sequences of maladaptive behavior in aggressive children: a T-Pattern analysis in structured tasks
type: item
description: Assessing childhood behavioral problems faces limitations associated with early child development. In this context, the systematic observation of dyadic interactions optimizes the collection of reliable data. This study examined differences in maladaptive behavior patterns between two groups of children (high and low aggression scores) during a structured task and a free-play situation. Participants were 10 girls and 12 boys (ages 41–73 months, M = 61.50, SD = 9.11) interacting with their mothers. Results showed that aggressive children displayed more maladaptive behaviors, particularly during the structured task, where the observed patterns consisted of annoyance, disobedience, negative physical contact, and complaints. In the free-play situation, fewer patterns of annoyance were observed, and there was an absence of negative physical contact. These findings suggest that structured tasks, which require adherence to rules and achievement of specific goals, are more effective in revealing problematic behaviors in aggressive children.

Subnational determinants of foreign direct investment in the context of nearshoring: the comparative case of Sonora and the leading states of Mexico
type: item
description: Nearshoring has altered the recent geography of foreign direct investment (FDI) in Mexico, accentuating regional disparities. This article comparatively analyzes the structural conditions that determine the capacity of the state of Sonora to attract nearshoring-related FDI, contrasting them with the country's leading states. It employs a qualitative comparative analysis (QCA) approach based on six dimensions: infrastructure, human capital, clusters, governance, security, and investment performance. The study hypothesizes that Sonora's border location does not constitute a structural advantage due to shortcomings in logistics, technical training, and institutional coordination. Results confirm that attracting FDI depends on complex territorial configurations, where the interaction between infrastructure, talent, and governance is crucial. The study offers a territorial perspective on nearshoring and a replicable framework for strengthening subnational competitiveness in Latin America.

Institutional insecurity and the neoliberalization of the territory: mobility and public transport in Ensenada, Baja California, Mexico
type: item
description: This paper shows how mobility conditions in Ensenada, Baja California, respond, on the one hand, to uncertainties generated by the current institutional framework that severely limit government management of public transportation and, on the other hand, to economic criteria of neoliberalism imposing the use and configuration of urban space, which creates developed areas and marginalized zones. Ensenada is an example of how government investment in urban development is oriented to favor activities that privilege private income over public services, such as public transportation. Questionnaires were applied to users, following a chain sampling technique, and interviews were carried out with key informants. Additionally, a rigorous document review and analysis was done applying a discourse analysis method. In conclusion, an institutional and organizational redesign is proposed, searching for operational effectiveness in the public management of public transport and mobility in Ensenada.

Tamaulipas' educational capabilities for developing human capital in the semiconductor industry: diagnosis of secondary and higher education
type: item
description: This research aimed to evaluate the level of vocational programs and subjects related to the semiconductor industry, focusing on human capital training in secondary and higher education levels. A mixed-methods approach was used to analyze institutional coverage, infrastructure, and program offerings. Through a review of documents and official data from the Tamaulipas Education Ministry, as well as interviews with officials and teachers, it was found that technical programs showed limited progress. Also, while there is evidence of teacher training, significant improvements in infrastructure and curriculum updates are necessary. This research suggests a need to innovate programs and courses tailored to the semiconductor industry by providing teachers with training in new academic topics, thereby equipping students with the knowledge required in the field. Evidence indicates that Tamaulipas has potential but requires increased investment and greater integration between academia and industry.

Circular Economy and its alignment with sustainable development: a systematic literature review
type: item
description: The literature on circular economy (CE) and sustainable development exhibits uneven coverage of the three sustainability dimensions (social, economic, and environmental), with the social dimension being the least addressed. This article aims to analyze the congruence between CE practices and sustainable development as well as to identify a coherent theoretical link between those practices and the three dimensions. To this end, a systematic literature review was carried out, drawing primarily on Web of Science (WoS) and incorporating studies on sustainability, CE, and carbon performance. A systematic approach was applied to classify and examine the retrieved papers, integrating conceptual elements and theoretical frameworks. Results show a consistent theoretical articulation between CE and sustainability while confirming the comparatively limited attention to the social dimension in the literature. Finally, the study offers a rigorous and comprehensive synthesis of the state of the art and highlights relevant gaps for future research.

Irrational beliefs and their influence on the level of academic stress in university students
type: item
description: Academic stress encounters different stressors that limit students' academic performance; therefore, one of these factors is addressed: irrational beliefs. The objective of this study was to determine the extent to which an intervention program to reduce irrational beliefs influences on the level of academic stress presented by fifth-semester students of the Bachelor of Education Sciences program at the Universidad Pedagógica de Durango. A quantitative inquiry with explanatory scope and experimental design was conducted. The instrument applied was the Systemic Cognitive Inventory for the Study of Academic Stress (SISCO) (Barraza, 2006). The main results show that academic stress decreased significantly in the experimental group after the intervention (0.000); likewise, this reduction was significant (0.012) compared to the control group.

Analysis of environmental regulations at state level in Mexico
type: item
description: In Mexico, each state must have an environmental protection law; however, the current status of these regulations in the states is unknown. Therefore, the objective was to analyze the status of state environmental laws in Mexico. For each state, environmental laws were identified and analyzed according to different parameters of validity and content using descriptive and inferential statistics (simple linear correlation). Some parameters were found to be significantly correlated (years of antique with total updates), while others had low levels of significance (states and categories). To achieve sustainability, having adequate regulations at the national level is not enough; it is also necessary to pursue the development of state environmental legislation to promote adequate environmental practices at different levels of jurisdiction. There may be a gap in certain topics, such as water, which is poorly legislated at the state level because it falls under federal jurisdiction.
