¿Por qué la ciencia mantiene un punto de vista masculino?
No full textEl artículo analiza la persistente perspectiva masculina en la ciencia, destacando la subrepresentación y discriminación de las mujeres, especialmente en ciencias exactas e ingeniería. Se enfatiza la necesidad de reconocer las contribuciones femeninas y reformar la educación para incluir visiones más inclusivas. El texto también aborda cómo la baja participación femenina afecta la diversidad y equidad en la ciencia, perpetuando sesgos y desigualdades. Subraya la importancia de abordar estas cuestiones para crear un entorno científico más inclusivo y diverso, concluyendo que el cambio hacia prácticas más equitativas es crucial para el progreso científico
Popular election of judges: Analysis of Judicial Reform in Mexico
No full textThe Judicial Reform published on September 15, 2024 substantially changes how judges are elected in Mexico, since now judges will be elected through popular vote. The election of judges is very controversial among a large part of society and the Mexican political opposition due to the significant intervention of the government in the election, as well as the possible loss of expertise of judges. By using a dogmatic methodology based on the doctrinal contributions of various jurists who have carried out analyses regarding the separation of powers, jurisdictional autonomy, the democratic legitimacy of judges, and their popular election, it is argued that the changes should not be conceptually controversial, since the direct participation of citizens in the election of judges generally guarantees jurisdictional autonomy. However, it is concluded that with the Judicial Reform, doubts remain regarding its execution. Also, there is uncertainty due to the government’s intervention in the election of judges and the lack of requirements to aspire to a jurisdictional position. Consequently, some proposals are presented to address the questions arising from the Judicial Reform, for example, maintaining the popular election only for the positions of judges of the National Supreme Court of Justice, magistrates of the ..
Algebraic identifiers for an inerter-based passive suspension system
No full textIn this work, the focus is on the analysis and formulation of identifiers for the physical properties of a quarter-vehicle suspension, such as suspended mass, spring stiffness, damping, and inertance, using a mechanical network based on an inerter. The methodology employed to obtain these identifiers is known as algebraic identification. To develop the algebraic estimators, the mathematical model of a passive suspension was utilized by implementing the C4 mechanical network (TID), considering the effects of translational inertia. The proposed algebraic identifiers allow for the calculation of the physical parameter values of the system in two distinct situations: under a constant harmonic force and with a random signal that simulates road dynamics. The numerical analysis of the identifiers shows that it is feasible to obtain the values of mass, damping, stiffness, and inertance parameters of the passive suspension within a very short time interval, not exceeding 2 seconds
Mathematical journal as strategy to develop skills in learning addition
No full textThis paper explores the use of the mathematical journal as a teaching strategy to develop addition skills in second-grade elementary school students. The intervention was carried out with a group of 28 students from an elementary school in Ciudad Juárez, Chihuahua, Mexico, who were assigned a specific notebook to document addition problems based on everyday situations. The methodology included initial activities, increasing the complexity of the problems, and contextualizing them in practical scenarios. The results indicate that this tool not only improved numerical skills but also fostered critical thinking and motivation toward mathematics. Students showed greater willingness to participate and contextualized mathematical problems in their daily lives, which facilitated meaningful learning. This innovative approach adds value by considering both the students' sociocultural context and their daily experiences, promoting more inclusive learning. The implementation of the mathematical journal as a teaching resource proved effective in improving addition skills and strengthening students' commitment to mathematics
Study on fruit and seed morphology and morphometry, seed phytochemicals, and germination characterization in three populations of Echinocereus stramineus(Cactaceae) at Ciudad Juárez Municipality, Chihuahua, Mexico
No full textIn this study, the fruit and seed morphological and morphometric parameters, the seed phytochemical content, and the germination process were analyzed for three populations ofEchinocereus stramineuslocated at Juárez Municipality, Chihuahua, Mexico. The morphometric variables were measured for each fruit and seeds obtained from each one.The seeds were subjected to three times of immersion in H2SO4as scarification treatment, allowing the seed development for 21 daysfor the characterization of the germination process. The germination percentage, mean germination time, germination speed, and mean germination speed were calculated. The seedling morphometry was also measured for all treatments. The concentration of reducing sugars, total phenols, tannins, flavonoids, andantioxidant activity (DPPH and FRAP) were determined for seeds under basal conditions. The fruits from the three populations showed significant differences in length and width, with the Sierra of Ciudad Juárez(SCJ)population having the longest and widest fruits.TheSCJ seeds had the highest mass values, while those from the Sierra of Presidio (SP)and SCP populations showed the highest length, length/width ratio, area, and perimeter. Immersionin H2SO4improved the germination percentage in SCJ and SP seeds. This treatment also caused a gradual decrease in the mean germination time and a progressive increase in the mean germination rate and germination speed index across seeds from all three populations as the immersion time increased. Similarly, the seedling stem length and area in SP seeds increased with immersiontime. The seeds from the SP population had the highest reducing sugar content, while those from the Sierra of Samalayuca (SS) population showed the highest levels of flavonoids, phenolics, tannins, and antioxidant activit
Evaluation of good governance practices in the Citizen Participation Council of the Historic Center and Built Heritage of Puebla
No full textThe establishment of public bodies for the territorial management of areas of material heritage interest has become a matter of interest to citizens in the municipality of Puebla, Puebla, in recent decades. In 2006, a public body was established to assists the municipal public administration in addressing issues of protection and restoration in the polygon of the monument zone, the Citizen Participation Council of the Historic Center and Built Heritage (CPC-HC&BH). This paper evaluates the good governance practices in the CPC-HC&BH, which aims to determine the quality of its mechanisms and the instruments that have been developed to achieve democratic processes within the organization
