Transfers and land demand for housing: Evidence from a municipality in northwestern México

Nicolás Guadalupe Zúñiga Espinoza (2021, [Artículo, Artículo])

Objective: to analyze the destination of conditional transfers (TC) to finance public services on land managed for housing in a municipality in the Northwest of Mexico. Methodology: based on semi-structured interviews, analysis of documents and data consulted in Inegi, Coneval, Inafed, Municipal Governments of Guasave and State of Sinaloa, it was possible to develop this work for the period 2013 to June 2020. Results: the evidence indicates that of the 6.9-hectare surface managed for housing, 50 % of the lots are vacant and in only a part of them there are houses or unfinished constructions (17 %). It is more about an interest in fattening land and taking advantage of financing, with transfers, to introduce free public services such as electricity, water and drainage.

Bacterial communities in the rhizosphere at different growth stages of maize cultivated in soil under conventional and conservation agricultural practices

Yendi Navarro-Noya Bram Govaerts Nele Verhulst Luc Dendooven (2022, [Artículo])

Farmers in Mexico till soil intensively, remove crop residues for fodder and grow maize often in monoculture. Conservation agriculture (CA), including minimal tillage, crop residue retention and crop diversification, is proposed as a more sustainable alternative. In this study, we determined the effect of agricultural practices and the developing maize rhizosphere on soil bacterial communities. Bulk and maize (Zea mays L.) rhizosphere soil under conventional practices (CP) and CA were sampled during the vegetative, flowering and grain filling stage, and 16S rRNA metabarcoding was used to assess bacterial diversity and community structure. The functional diversity was inferred from the bacterial taxa using PICRUSt. Conservation agriculture positively affected taxonomic and functional diversity compared to CP. The agricultural practice was the most important factor in defining the structure of bacterial communities, even more so than rhizosphere and plant growth stage. The rhizosphere enriched fast growing copiotrophic bacteria, such as Rhizobiales, Sphingomonadales, Xanthomonadales, and Burkholderiales, while in the bulk soil of CP other copiotrophs were enriched, e.g., Halomonas and Bacillus. The bacterial community in the maize bulk soil resembled each other more than in the rhizosphere of CA and CP. The bacterial community structure, and taxonomic and functional diversity in the maize rhizosphere changed with maize development and the differences between the bulk soil and the rhizosphere were more accentuated when the plant aged. Although agricultural practices did not alter the effect of the rhizosphere on the soil bacterial communities in the flowering and grain filling stage, they did in the vegetative stage.

Economic inequality and the impact of cash transfers in the state of Veracruz, México, 2008 to 2020

José Alejandro Pérez-Nájera Rogelio Javier Rendón Hernández (2023, [Artículo, Artículo])

Income inequality in Mexico is extremely high and the federal states are considerably heterogeneous, which is why a regional analysis allows us to identify the fundamental characteristics, trends, and regional conditions for the implementation of redistributive policies.  We used microdata from the National Household Income and Expenditure Survey (ENIGH) to analyze the evolution of income inequality in the state of Veracruz during the 2008-2020 period; To identify its sources and investigate how it was affected by monetary transfers, the income decomposition method is used to identify the ENIGH income sources and investigate preliminary COVID-19 effects. The results show evidence of a decrease in inequality in the period; relatively and marginally, it is identified that the observed decrease can be attributed to cash transfers. In recent years, transfers represented 30% of the income of the lowest deciles (I, II, and III) and the income elasticity of the Gini coefficient indicates that their increase represents a decrease in inequality.

Análisis de las conexiones matemáticas en la enseñanza y aprendizaje de la derivada basado en un networking of theories entre la Teoría de las conexiones y el Enfoque ontosemiótico.

In research in Mathematics Education, models have been reported to analyze mathematical connections in which specific connection categories are considered. In the literature, it was identified that the most used model is the Businskas with contributions from other researchers. However, the problem refers to the fact that some categories of connections limit the analysis of mathematical activity and, therefore, the research suggests that the established categories are validated and, if possible, new categories of connections are reported. Other investigations focused on exploring mathematical connections and understanding the derivative reveal that high school students, pre-service teachers, and some in-service mathematics teachers have difficulty connecting multiple representations of the derivative (e.g., algebraic, or symbolic, verbal, graphic, tabular) and establish connections between partial meanings about this concept.

Study of modal coupling in tapered optical fibers

LUIS ALEJANDRO HERRERA PIAD (2019, [Tesis de doctorado])

La comunicación por fibra óptica es una forma de transmitir información mediante el envío de pulsos de luz a través de una fibra óptica. Desarrollados por primera vez en la década de los 70s, los sistemas de comunicación de fibra óptica han revolucionado la industria debido a sus ventajas sobre la transmisión eléctrica. Las tecnologías de telecomunicaciones y láseres se han relacionado recientemente con fibras de pocos modos, de área modal grande y multimodo. Más específicamente, se han propuesto linternas fotónicas, combinadores de fuentes y fibras multimodo para láseres de alta potencia y comunicaciones. Otro dispositivo que se usa frecuentemente en los láseres, sensores y otras sistemas de comunicaciones es la fibra óptica cónica o estrechada. Fue necesario maximizar la potencia óptica recolectada en una guía de onda desde el campo de difracción de un láser semiconductor; por lo tanto, la técnica de mapeo permitió la remodelación del campo capturado en el modo fundamental de la guía de onda de salida. Además, los sensores de fibra estrechada son capaces de medir diversas variables como índice de refracción, tensión, campo magnético, temperatura y señales acústicas. En comparación con las estructuras de fibra convencionales, las fibras ópticas estrechadas pueden proporcionar una serie de características útiles como un gran campo evanescente, capacidad de confinamiento, diámetro a pequeña escala y generación de supercontinuo, entre muchas otras. En este trabajo se propone una investigación sobre la interacción modal en fibras ópticas estrechadas para observar este dispositivo bajo diversos cambios físicos con el objetivo de proponer la geometría óptima que se implementará en las aplicaciones de detección y láseres de nuestro laboratorio.
