The current study presents a non-random, quantitative experimental investigation detailing the steps required to accredit a non-regulated test method (referred to as its own) under the ISO/IEC 17025:2017 standard and the criteria set by the Mexican Accreditation Entity (EMA). The focus is on the methodology employed to validate the test method, particularly emphasizing the precision of the measurement system, along with the total variation in and tolerance of its components. For the measurement analysis, repeatability and reproducibility (r&R) studies were conducted using a variance analysis method variant (ANOVA). This variant is highlighted for its ability to estimate deviations more accurately. Furthermore, the chosen model incorporates random effect measurements for all factors or components of system variation (operators, parts, interaction, and instrument). This approach demonstrates the reliability, accuracy, and precision of the proposed measurement system within the test method, leading to its subsequent accreditation under ISO/IEC 17025:2017 as a conformity assessment body.

Labor dynamics have changed in recent years, and women have increased their participation in various activities within the production and business industries. One of these sectors is mining, which presents both challenges and opportunities to promote gender equality and decent work. In light of this, the objective of the present study is to identify the limitations faced by women in the mining sector, framed within personal, family, social, and labor aspects, in relation to their educational level. Due to the nature of the study, a cross-sectional, descriptive, and non-experimental investigation was proposed. The sample consisted of more than 50 companies distributed throughout the Mexican Republic, with a total of 316 female workers in the mining sector. The main results show greater limitations in labor and family aspects. Moreover, educational levels directly affect how women perceive the impact of working in mining on the various areas in which they operate.

This research explores the effectiveness of Quality Management Systems (QMSs) certified under the ISO 9001 standard by applying Hotelling’s multivariate statistical test T². This research focuses on organizations in central Mexico, evaluating whether the adoption of the ISO 9001 standard generates the promised benefits (by the International Standardization Organization itself), such as process improvement, increased customer satisfaction, higher sales, and increased revenues. Using a comprehensive framework grounded in ISO 10014 and incorporating statistical tools, such as descriptive analysis, regression, simulation, and Hotelling’s T² test, this study examined performance differences across sectors and pinpointed the critical factors impacting QMS outcomes. The results demonstrated notable advantages, including average improvements exceeding 20% in anticipated benefits. Furthermore, the analysis underscored the importance of QMS maturity, process enhancement, and customer satisfaction as pivotal drivers of QMS success. Sector-specific patterns also emerged, revealing that public organizations prioritize process efficiency and customer satisfaction, whereas private entities emphasize sales and revenue growth. By employing multivariate techniques, this research offers valuable insights into the interconnected factors affecting QMS effectiveness and provides actionable recommendations for organizations to enhance their QMS performance.

This work aims to analyze and explain the didactic strategies used to achieve meaningful learning. It begins under the assumption that if meaningful learning is created and students are given freedom and confidence, they can find their own answers and develop their knowledge both in the classroom and in practical life. The method used is the analytical-descriptive one of the reviews of the literature of the main authors who have given rise to this approach, its elements, and the didactic strategies used. It is concluded that the design and implementation of didactic strategies focused on meaningful learning with the application of active didactic methodologies and strategies in meaningful learning processes depending on the context in which it takes place obtains better results in the training of professionals.

Systems thinking is not a static concept, but rather a dynamic and evolving paradigm that continually adapts to the challenges of its time, becoming more refined and applicable in different areas, such as education. The main objective of the study is to identify the relationship between academic performance and the pedagogical strategies used to promote systems thinking in undergraduate and graduate students in STEM disciplines (science, technology, engineering, and mathematics). The method used is quantitative research with a non-experimental cross-sectional design. For data collection, a 25-item Likert scale called “STEM Pedagogical Strategies” was used, with an overall Cronbach’s alpha coefficient of α = 0.985. The instrument measures students’ perceptions of the application of five key strategies: problem-based learning, thinking routines, system maps and visual diagrams, design thinking, and system dynamics. The sample consisted of 350 undergraduate and graduate students in STEM fields. The main results show that there is a significant correlation between students’ academic performance and the pedagogical strategies of thinking routines and design thinking. Likewise, the skills developed through systems thinking, as shown in the available literature, would be the basis for fostering collaboration, complex problem solving, and students’ ability to become “systems”.

Recent advancements have been observed in the global legal framework, particularly in the recognition of Indigenous peoples’ rights, among which the right to self-determination stands out. This right encompasses the ability to define their political status and to pursue economic, social, and cultural development autonomously. The Inter-American Commission on Human Rights (IACHR) has identified six criteria to evaluate adherence to these rights. This study aims to assess the progress made by Chile, Colombia, and Mexico in meeting these criteria. Employing a non-experimental, cross-sectional, and exploratory research design, the study utilized a questionnaire based on a Likert scale to gather data from residents of Indigenous communities within the three countries under consideration to measure the perception that these individuals have regarding the compliance with the six standards of the IACHR, and specific questions have been designed based on the content of each standard. Once the degree of self-determination is understood, a multivariate analysis technique (Principal Component Analysis) will be used to compare the level of progress by country. The data collection instruments were applied in 2023 (September/November), with the results processed and the final report drafted in early 2024. Findings suggest that the criterion most adequately met is that of cultural identity and non-discrimination, whereas the criterion pertaining to the right to prior, free, and informed consultation and consent is the least fulfilled. Through principal component analysis, it was noted that Colombia exhibits a higher level of compliance with the right to self-determination, followed by Mexico, with Chile demonstrating a divergence and lagging in progress. The study concludes that a significant challenge for these countries lies in continuing efforts to effectively meet these standards and ensure the right to self-determination for Indigenous and tribal peoples.
