Análisis interferométrico de caos óptico

Fabian Camilo CUBILLOS Morales (2020)

It is proposed a desing based on the Young’s experimental setup for implement caos in interferometric systems. First, correlation is studied for a system where the point sources are distributed in random way, this is for analize the caos ideas in the setup. For this, a rigid double pendulum system was used with the point sources in it. It is shown that the irradiance distribution follows a partial, non-linear and second order differential equation, whose solution allows to establish properties analogous to the mathematical structure of entropy. In addition, a description of the irradiance correlation processes is made using the matrix formalism.

Se propone un diseño basado en el arreglo experimental de Young para implementar caos en sistemas inteferómetricos. En primera instancia se estudia la correlación en un sistema donde las fuentes puntuales se distribuyen de forma aleatoria, esto con la intención de analizar nociones de caos en dicho arreglo. Para ello se utilizó un sistema de péndulo doble rígido con las fuentes puntuales en él. Se muestra que la distribución de irradiancia sigue una ecuación diferencial parcial, no-lineal y de segundo orden, cuya solución permite establecer propiedades análogas a la estructura matemática de la entropía. En adición se realiza una descripción de los procesos de correlación en irradiancia usando el formalismo matricial.

Impact of the social network Facebook in the higher education process of mathematics considering the science of data

Ricardo-Adán Salas-Rueda Rodrigo Salas (2021)

This mixed research aims to analyze the use of the social network Facebook in Computational Mathematics and Basic Applied Statistics during the 2017 school year through data science (decision tree technique). The sample is composed of 54 students of the Bachelor of Administration, Information Technology, Marketing and Commerce. The decision tree technique allows the identification of 8 predictive models about the interaction and communication of students in the social network Facebook during the teaching and learning process. Likewise, the qualitative approach analyzes the use of this social network considering the variables on the meeting point, distribution of contents, motivation, support tool in learning and satisfaction. The results indicate that Facebook is a tool that facilitates the teaching and learning process in the field of mathematics. In fact, the linear regression indicates that the publication of tasks, sending of messages among students, creation of comments on the wall and consultation of videos in this social network positively influence the interaction and communication of students during the teaching and learning process. Therefore, this qualitative and quantitative study recommends the incorporation of the social network Facebook in school activities with the purpose of innovating educational practices.

Intercultural universities in Mexico at the crossroads

León Enrique Avila Romero AGUSTIN AVILA ROMERO (2021)

Intercultural Universities in Mexico took place to promote access to higher education of indigenous population, which has historically experienced a lag. In 2003 the General Coordination of Intercultural and Bilingual Education (CGEIB) is created by the federal government in order to generate proposals that incorporate knowledge, languages and culture of indigenous educational processes. By 2014 there were ten Institutions of Higher Education, which are grouped in the University Network Intercultural (Redui), and located in Mexican states with significant presence of native people. This paper seeks to analyze three great moments: a) the genesis of intercultural universities in Mexico, b) their evolution and development, and c) analysis and actual situation. Finally, this inquiry will analyze the scope, difficulties and problems that the Unich has had.

Organizational culture and competitive intelligence in a higher education institution of northern Mexico

Armando Esquinca Carmen Patricia Jiménez Hugo Gaggiotti (2022)

The objective is to describe the organizational culture (OC) of managers, administrators and teachers of higher institution in the north of Mexico and their vision of competitive intelligence (CI) in the collection of information for the achievement of institutional objectives. A qualitative and case study was conducted, with semi-structured interviews and grounded theory, in a theoretical sample of 14 participants and institutional documents. The coding was selective theoretical with a hypothetico-deductive model based on Cameron and Quinn's OC types and the CI cycle. It was found that the results of market OC that the institutional plan projects, only correspond to what the administrative mention and CI in the 2021 projection as institutionalized and regulated, although currently lack of knowledge about the CI of the institution and unification of criteria on who and what strategies they carry out. The document includes recommendations for the cultural change that is required in the 2021 projection.

Pedagogía del diseño en el contexto COVID-19: una experiencia educativa en el aula virtual

Eska Elena Solano Meneses (2022)

La enseñanza del diseño guarda grandes distancias que la alejan de otros campos disciplinares, tanto por sus características peculiares como disciplina eminentemente creadora como por la manera en que los procesos de enseñanza se adecuan a estas particularidades. A esta peculiaridad se agrega la situación que en marzo del 2020 y en el contexto de la pandemia por COVID-19 obligó a un confinamiento generalizado en México, y con ello a la gestión en un modelo virtual sostenido en plataformas tecnológicas de aprendizaje y aplicaciones para reuniones virtuales. La propuesta de una educación basada en el aprendizaje activo (Tishman, 1999), aunada a la idea de desarrollar la autogestión en los alumnos (Góngora, 2010), se presentan ensambladas a una actitud creativa impulsada intencionalmente por el docente a través de la construcción de ambientes retadores y lúdicos virtuales. El presente trabajo corresponde a un análisis y crítica de las experiencias creativas generadas en la educación apoyada en medios virtuales, diseñadas mediante estrategias instruccionales, a través de las que se ha pretendido consolidar una visión educativa orientada a un aprendizaje significativo. Se concluye que las propuestas de los últimos avances a nivel educativo, obligadas de alguna manera por el contexto de la pandemia, proporcionan nuevas plataformas y recursos tecnológicos para generar un estilo de enseñanza más amigable para el alumno, que aproveche las ventajas de recursos que procuren un diseño cordial pero también retador, donde las acciones realizadas dentro y fuera del aula virtual le marquen y le signifiquen.

Rendimientos a la educación superior en México: ajuste por sesgo utilizando máxima verosimilitud

ANDRES ZAMUDIO CARRILLO (1995)

En el presente documento se trabaja con un segmento del ciclo escolar: la educación superior. Para este sector reviste especial importancia el problema de la endogeneidad de la escolaridad, ya que en el acceso a la educación superior en México influyen tanto las características de los individuos como los factores socioeconómicos. Muchos de estos factores forman parte, al mismo tiempo, de la decisión de continuar con estudios superiores y del desempeño laboral del individuo.

Adsorción de hidrógeno a alta presión en zeolitas naturales y sintéticas

SANDRA LOERA SERNA MARIA ELBA ORTIZ ROMERO VARGAS (2015)

El continuo aumento de la demanda energética mundial está generando en los últimos años una creciente preocupación, ya que los recursos de los combustibles fósiles, que son la fuente energética por excelencia, son limitados y su uso conlleva a un negativo impacto ambiental. Debido a esto, se está considerando la implantación de fuentes alternas, una de ellas es el hidrógeno. Sin embargo, el almacenamiento y transporte de hidrógeno es un problema que aún no se ha resuelto, en la actualidad se utilizan materiales porosos para retenerlo y transportarlo. Este método resulta eficaz, seguro y económicamente viable. Las zeolitas son materiales usados en el transporte y almacenamiento de hidrógeno, debido a que son materiales porosos y adsorbentes, con diversas características y propiedades. En el presente trabajo se propone la caracterización de zeolitas naturales (clinoptilolita, mordenita y eriotnita) y zeolitas sintéticas (A, y Beta) para determinar sus propiedades fisicoquímicas, y la homogenización de sus iones de intercambio, para aplicarlas a la adsorción hidrógeno a alta presión.

The continuous increase in global energy demand is generating in recent years a growing concern, since resources of fossil fuels, which are the energy source for excellence, are limited and its use leads to a negative environmental impact. Because of this, it is considering the introduction of alternative sources, one of them is hydrogen. However, hydrogen storage and transport is a problem that has not yet been resolved, now porous materials are used to hold and transport. This method is effective, safe and economically viable. Zeolites are used in transport and storage of hydrogen, because they are porous and adsorbent materials, with different characteristics and properties. In this paper the characterization of natural zeolites (clinoptilolite, mordenite and eriotnite) and synthetic zeolites (A, y and Beta) to determine their physicochemical properties, and the homogenization of the ion exchange is proposed to apply to the hydrogen adsorption high pressure.

Sexual harassment and stalking in female university students: negative emotions and coping with these forms of gender-based violence

Karla Jazmín Rodríguez Hernández ADRIANA RODRIGUEZ BARRAZA Maria Carolina Agoff (2023)

Stalking and sexual harassment, as expressions of gender violence in the field of higher education, are very pressing problems as they have been exhibited by the protest movements that have arisen in Higher Education Institutions. The objective of this work is to analyze the narratives of university women who experienced stalking and/or sexual harassment in Higher Education Institutions in the municipalities of Tampico and Ciudad Madero in the state of Tamaulipas. The purpose was to learn about their experiences and their way of dealing with these forms of gender violence, using qualitative research and a phenomenological design. The technique used for data collection was the semi-structured interview. The selection of the informants was based on intentional sampling and the number of cases examined was guided by the saturation criterion, the total number of participants being thirteen. The analysis of the interviews shows that acts of stalking and sexual harassment provoke various emotions in women that can shed light on the problem of violence from the perspective of the victims, instead of considering only their own explanations, which are often rationalized or consistent with socially legitimized meanings. In sum, the study of emotions allows us to conclude that women within the university context suffer from a psychophysical discomfort that does not allow them to live a full university life.
