Ciudad Juarez from historical sketch of national migration policies

Luis Fernando Noyola Rojas Luis Manuel Lara Rodríguez (2023, [Artículo, Artículo])

The context of migration in the Mexican case and its migration policies are analyzed here, taking the case of Ciudad Juarez as a node of movement and link of said policies; for this, the work is divided into four sections. A historical review of the way of how migration policies, through programs operated by different institutions and spheres of government, have worked through the manifestations of the domestic and international Mexican migration it is proposed. It also serves to contextualize and to understand how they are created and why the objectives they intend to meet are more orientated to immediate problems rather to recognize the complexity of migratory problems, in need of specific policies.

Transformation and innovation of knowledge in the construction and sustainable function of housing at the headwaters of San Juan Chamula.

Alejandra Trujillo Miguel Sánchez Álvarez (2022, [Artículo, Artículo])

SUMMARY

 

San Juan Chamula, Chiapas, is one of the most representative cultures of the native peoples of Mexico. The municipal seat is made up of three main neighborhoods: San Juan, San Sebastián and San Pedro. In ancient times, the architectural design of the houses was made of materials such as straw, adobe, bajareque and others of organic origin, which were part of the natural environment of the inhabitants. Thus, houses were built based on the use of natural elements available to the inhabitants as a result of the use of primary sector activity.

 

From the Chamula worldview housing has played functions for rest and shelter, therefore it was considered as a sacred place. When building one, ceremonies and offerings were carried out to appease any disgust of the guardians of Mother Earth, as they considered that nature had life, and to avoid any misfortune among the members of the family. For this, it was necessary to offer music, songs, and special dishes to feed the house and the Earth, so there would be harmony and well-being. Today, that worldview has been disrupted by the presence of multiple religions and other factors.

 

Chamula housing has gone through different stages of transition, from 1990 onwards, it was made of materials such as bricks, blocks and cement. With international migration and the arrival of young Chamula in the United States, changes in the building styles and function of housing are observed, as well as a loss of Chamula-type architectural knowledge, so that traditional architectural knowledge remains only with the elderly. Nowadays, Chamula masons and house builders opt for a foreign architectural design like California, thus changing their cultural identity, their way of life and their relationship with nature.

Militancia partidaria y toma de decisiones en el Movimiento Regeneración Nacional.

Mariela Díaz Sandoval Alberto Espejel Espinoza (2018, [Artículo])

The purpose of the article is to show a qualitative approach to the opinion of the militancy on decision¿making inside the National Regeneration Movement (Morena). Hence, the paper accounts for an actor, of whom little evidence has been provided, in the studies on intra¿democracy: the militant. In that sense, the questions that guided the research were: Who makes the major decisions with in Morena? What role do the militants have when it comes to selecting leaders and candidates? What does the militant think about the way in which are made with in the party? By conducting in¿depth interviews and document analysis, the main findings show the concentration of power in Morena, both statutory level and in the partisan reality. Coupled with an active and dissatisfied militancy, but at the same time justifies the concentration of power in Andrés Manuel López Obrador.

COORDINATED CONTROL OF A 6-DOF ROBOTIC MANIPULATOR EMPLOYING VIRTUAL MODELS OF ITS ACTUATORS

Jessica Villalobos (2023, [Tesis de doctorado])

"This study proposes a scheme that combines the model reference control with the internal model control to impose a first-order behavior on the speed control system of direct current motors. This scheme is used as the internal loop to control the position of a model to use it as the reference for the physical motor.

This work also presents an inverse kinematic solution for the UR5 and algorithms to choose angles that do not lead to singularities. These algorithms can be used in independent joint control schemes such as the one proposed in this document."

Impactos del desplazamiento forzado sobre el sector agrícola: el caso colombiano

Wilmer Vladimir Ferrer Vargas (2021, [Tesis de maestría])

La intensificación del conflicto civil colombiano tuvo como una de sus peores consecuencias el desplazamiento forzado. El propósito de este trabajo es estudiar el impacto del desplazamiento forzado en el sector agrícola colombiano. Con este fin, se estudiaron las características de los principales cultivos. Para responder a esta pregunta se estima un modelo panel de efectos fijos de para todos los municipios de Colombia entre 2011-2016. Los resultados muestran que el desplazamiento forzado tiene efectos negativos principalmente en las unidades familiares y estos efectos se amplifican en presencia de mercados ilegales.

Capability approach and life course cube applied to the migration of skilled women

Lidia Ivonne Munguía Ocampo Arlette Covarrubias (2023, [Artículo, Artículo])

A proposal is developed to integrate Amartya Sen's Capabilities Approach and the study of life trajectories, represented in the life course cube of Bernardi et al. (2019), taking as an empirical example the couple migration the skilled women. The life curse cube allows the visualization of the interdependencies between (1) the temporality of women's life course and the historical moment where the migration process occurs, (2) the individual, social, and environmental conversion factors that provide or restrict their ability to achieve those functionings they consider of value to their lives and how they exercise their agency to achieve their well-being, and (3) the micro, meso and macro levels of interaction that together connect life domains over time from the individual environment, the social relationships and considering external societal structures.

Climate change and the northern elephant seal (Mirounga angustirostris) population in Baja California, Mexico

M. Concepción García-Aguilar (2018, [Artículo])

The Earth0s climate is warming, especially in the mid- and high latitudes of the Northern Hemisphere. The northern elephant seal (Mirounga angustirostris) breeds and haul-outs on islands and the mainland of Baja California, Mexico, and California, U.S.A. At the beginning of the 21st century, numbers of elephant seals in California are increasing, but the status of Baja California populations is unknown, and some data suggest they may be decreasing. We hypothesize that the elephant seal population of Baja California is experiencing a decline because the animals are not migrating as far south due to warming sea and air temperatures. Here we assessed population trends of the Baja California population, and climate change in the region. The numbers of northern elephant seals in Baja California colonies have been decreasing since the 1990s, and both the surface waters off Baja California and the local air temperatures have warmed during the last three decades. We propose that declining population sizes may be attributable to decreased migration towards the southern portions of the range in response to the observed temperature increases. Further research is needed to confirm our hypothesis; however, if true, it would imply that elephant seal colonies of Baja California and California are not demographically isolated which would pose challenges to environmental and management policies between Mexico and the United States. © 2018 García-Aguilar et al.
