Teacher training in the state of Chihuahua: Between the health challenge and teacher resilience

Evangelina Cervantes Holguín Pavel Roel Gutiérrez Sandoval Cely Celene Ronquillo Chávez (2023, [Artículo, Artículo])

 

The article proposes to recover the response of the Teacher Training and Updating Institutions in the state of Chihuahua regarding the various challenges imposed by the Coronavirus Disease (COVID-19). The qualitative exercise analyzes the experience of 10 institutions based on the voice of their students, teachers, and principals regarding changes in academic, administrative, and organizational processes. It is concluded that the pandemic has affected each institution in different ways and with diverse intensity. Despite the achievements, the experience analyzed reveals the relative success of the using virtual platforms in the face of three basic conditions: connectivity, technological competencies, and socio-emotional skills of the teaching staff. It highlights the importance of implementing tutoring, resilience, or awareness actions of teachers and students' needs, feelings, and sufferings. It is opportune to recover the experiences of other institutions and to question especially students, thesis students and graduates.

THE RIGHT TO THE CITY AND URBAN-RURAL LINKAGES. COMMUNITY PARTICIPATION IN THE METROPOLITAN AREA OF TUXTLA GUTIERREZ, CHIAPAS.

Briseida Corzo Rivera Gabriel Castañeda Nolasco (2023, [Artículo, Artículo])

Access to water is a common struggle of the communities in the state of Chiapas, with the effects of urban expansion these struggles increase and with them the challenges that these populations already face, having a greater impact on the rural environment. The struggles to satisfy this basic need are a factor that has triggered processes that promote community participation. Based on a qualitative analysis, this paper compares two existing forms of participation in the rural communities of the Metropolitan Area of Tuxtla Gutierrez that allow the population to manage actions to improve their quality of life. The objective is to analyze how these processes promote or restrict the empowerment of the community and allow progress, not only in the population's access to water, but also in the construction of the right to the city. From the urban-rural linkages, the right to the city is discussed beyond the city, addressing other territories. The study identifies factors that show changes in the participation of the populations and strengthen the community, as well as factors in the relationships of the community and of the community with other actors that limit the scope of the processes.

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.

Big data, small explanatory and predictive power: Lessons from random forest modeling of on-farm yield variability and implications for data-driven agronomy

Martin van Ittersum (2023, [Artículo])

Context: Collection and analysis of large volumes of on-farm production data are widely seen as key to understanding yield variability among farmers and improving resource-use efficiency. Objective: The aim of this study was to assess the performance of statistical and machine learning methods to explain and predict crop yield across thousands of farmers’ fields in contrasting farming systems worldwide. Methods: A large database of 10,940 field-year combinations from three countries in different stages of agricultural intensification was analyzed. Random effects models were used to partition crop yield variability and random forest models were used to explain and predict crop yield within a cross-validation scheme with data re-sampling over space and time. Results: Yield variability in relative terms was smallest for wheat and barley in the Netherlands and for wheat in Ethiopia, intermediate for rice in the Philippines, and greatest for maize in Ethiopia. Random forest models comprising a total of 87 variables explained a maximum of 65 % of cereal yield variability in the Netherlands and less than 45 % of cereal yield variability in Ethiopia and in the Philippines. Crop management related variables were important to explain and predict cereal yields in Ethiopia, while predictive (i.e., known before the growing season) climatic variables and explanatory (i.e., known during or after the growing season) climatic variables were most important to explain and predict cereal yield variability in the Philippines and in the Netherlands, respectively. Finally, model cross-validation for regions or years not seen during model training reduced the R2 considerably for most crop x country combinations, while for wheat in the Netherlands this was model dependent. Conclusion: Big data from farmers’ fields is useful to explain on-farm yield variability to some extent, but not to predict it across time and space. Significance: The results call for moderate expectations towards big data and machine learning in agronomic studies, particularly for smallholder farms in the tropics where model performance was poorest independently of the variables considered and the cross-validation scheme used.

Política de lo materno de dirigentes barriales en el espacio público

David Luján Veron ANÍBAL PÉREZ CONTRERAS (2023, [Artículo])

"En este artículo se analiza un conjunto de relatos de dirigentes vecinales, recabados a partir de dos investigaciones doctorales concluidas, con el objetivo de desvelar los distintos modos en que las mujeres invocan roles tradicionalmente asociados a lo femenino —protección, cuidado, maternidad— para legitimarse en el espacio público y participar en la política local. Se argumentará que las mujeres observadas participan en la configuración de una “política de lo materno” que, pese a reforzar estereotipos tradicionales sobre el rol de las mujeres, constituye un reservorio de experiencias, aprendizajes y prácticas que pueden ser leídas en clave de politización y construcción de ciudadanía".

Socio-spatial segregation of socio-environmental assets of public green spaces in the city of Durango, Mexico

Carlos Alejandro Custodio González Tania Ortiz Patricia Catalina Medina Pérez (2024, [Artículo, Artículo])

The current development model's accumulation logic has resulted in the emergence and consolidation of social processes like segregation, leading to differentiated access and availability of urban goods and services among social groups based on socioeconomic, ethnic, or societal standing. The current development model's accumulation logic has resulted in the emergence and consolidation of social processes like segregation, leading to differentiated access and availability of urban goods and services among social groups based on socioeconomic, ethnic, or societal standing. This disparity impacts employment levels, educational performance, urban decay, and environmental degradation. In this context, the article aims to examine the socio-spatial segregation in the access to socio-environmental amenities provided by public green spaces (EVP) in a medium-sized city, specifically Durango, Mexico. The analysis utilizes spatial analysis and statistical methods that involve five variables associated with EVPs: surface area, percentage, number, density, and the socioeconomic level of the population. A spatial pattern of segregation was identified through these variables, resulting in four clusters that impact how the city of Durango is inhabited, produced, reproduced, lived, and constructed.
