This article presents an analysis of the proportion of the population that lives in the 20 top cities of Mexico. Population that suffers from moderate to severe Depressive Symptoms (DS) in relation to urban and socioeconomic factors typical of urban territories and comparing them with people living in rural or non-urban environments that suffers DS. To check this, we generated the Complex Index of Socioeconomic and Urban Conditions (CISUC), based on the Mind the GAPS framework, a model that relates the susceptibility or prevention of mental illness in cities based on urban factors, we also used socioeconomic indicators that exist in Mexican cities. For the construction of the ICCSU database, we used data from the National Health and Nutrition Survey in the years 2006, 2012 and 2018-19 and the data of the Mexican Institute for Competitiveness, A.C. and National Institute of Statistics and Geography in the same years. The results obtained from CISUC were reinforced with the use of a panel data model. The findings that we obtained reveal that there is a more important correlation between cities and people who suffer from moderate to severe DS than in rural areas, a condition that intensifies with the socioeconomic conditions of the population, for example, their socioeconomic stratum, their gender, and present urban marginalization. This allows to generate future discussions about other types of diseases such as anxiety, depression, stress, loneliness, and schizophrenia for large population groups. The panel model yields a lower goodness of adjustment, due to the lack of more time points, however, it points out that improvements in socioeconomic and urban conditions slightly reduce depressive symptoms.

El huevo de traspatio: características físicas y desempeño en pruebas de incubación artificial

The backyard egg: physical characteristics and performance in artificial incubation tests

MARCO ANTONIO CAMACHO ESCOBAR MARTHA PATRICIA JEREZ SALAS JUAN CARLOS GARCIA LOPEZ SERAFIN JACOBO LOPEZ GARRIDO EDGAR IVAN SANCHEZ BERNAL (2019, [Artículo])

El huevo de traspatio es de tamaño variable, en comparación con el huevo incubable comercial. El objetivo fue incubar huevo de traspatio para conocer las características físicas y desempeño en pruebas de incubación artificial. Se incubaron 1129 huevos: 1002 de gallinas criollas, 68 de gallinas araucanas y 59 de pava. Las variables evaluadas fueron peso, eje longitudinal, diámetro máximo polar, diámetro ecuatorial, diámetro mínimo polar e índice de forma, cascarón quebrado o cascarón sucio, fertilidad, incubabilidad y mortalidad embrionaria total, temprana, intermedia y tardía. El huevo de pava tuvo mayor peso, eje longitudinal, diámetro máximo polar, diámetro ecuatorial, diámetro mínimo polar y fertilidad (p < 0.05), también tuvo menor índice de forma que los huevos de gallina criolla y gallina araucana (p < 0.05). El huevo de gallina araucana presentó mayor incubabilidad y menor mortalidad embrionaria total (p < 0.05). Las características y desempeño del huevo criollo son diferentes al huevo incubable; por ello, los criterios de uniformidad e incubación comercial no le son, precisamente, adecuados para la incubación

The backyard egg is small in comparison with the incubating egg. The objective was to incubate backyard eggs to know physical characteristics and performance in artificial incubation tests. 1129 eggs were incubated: 1002 creole hens’ eggs, 68 araucana hens’ eggs and 59 turkeys’ eggs. The evaluated variables were weight, longitudinal axis, maximum polar diameter, equatorial diameter, polar minimum diameter, shape index, broken shell or dirty shell, fertility, hatchability, and total early, intermediate, and late embryonic mortality. The turkey egg had greater weight, length, maximum polar diameter, equatorial diameter, minimum polar diameter and fertility (p < 0.05). They also had a lower rate of form than the eggs of the creole and araucanian hens (p < 0.05). The araucanian chicken egg showed greater hatchability and lower total embryonic mortality (p < 0.05). The characteristics and performance of the creole egg are different from the incubable egg; therefore, the criteria of uniformity and commercial incubation are not, precisely, suitable for incubation

La hegemonia cultural como impedimento para la protección jurídica de los derechos económicos, sociales, culturales y ambientales en México

ITZEL ARRIAGA HURTADO (2021, [Capítulo de libro])

El presente capítulo de libro tiene como objetivo analizar el sistema de hegemonía cultural presente en la realidad social en México y mostrar la afectación que provoca en la protección jurídica de los Derechos Económicos, Sociales, Culturales y Ambientales (DESCA) en México. Se presenta en primer término una concepción de la actual perspectiva de la figura hegemonía cultural y cómo esta se mantiene superpuesta a los sistemas jurídicos de cualquier circunscripción, determinados dichos sistemas por una clase dominante, y particualrmente se realiza una propuesta de las categorías hegemónicas consideradas como las principales ideologias de pensamiento en la evolución humana que han ido determinando el dominio y superioridad de sectores de poblacion para su desarrollo, ello de conformidad con los aspectos humanos que generan una intersección y por lo tanto colocación del sujeto de derechos, en materia de derechos humanos, que le impliden acceder a un sistema jurídico de protección por parte del sistema gubernamental, de manera especifica los derechos económicos, sociales, culturales y ambientales.

Influence of poverty concerns on demand for healthier processed foods: A field experiment in Mexico City

Marrit Van den Berg Jason Donovan (2023, [Artículo])

Living in poverty can present cognitive biases that exacerbate constraints to achieving healthier diets. Better diets could imply food choice upgrades within certain food categories, such as electing processed foods with an improved nutritional profile. This study evaluated the influence of monetary and health concerns on the willingness to pay (WTP) for healthier processed foods in a low-income section of Mexico City. We employed priming techniques from the scarcity literature, which are applied for the first time to healthier food purchasing behaviours in low-income settings. Our predictions are based on a dual system framework, with choices resulting from the interaction of deliberative and affective aspects. The WTP was elicited through a BDM mechanism with 423 participants. Results showed that induced poverty concerns reduced the valuations of one of the study's healthier food varieties by 0.17 standard deviations. The latter effect did not differ by income level. The WTP for a healthier bread product but one with relatively high sugar and fat content was reduced by induced poverty concerns only among certain consumers without bread purchasing restrictions (78% of the sample). Potential mechanisms were assessed through regression analysis and structural equation modelling. The relationship between poverty concerns and WTP was mediated by increased levels of stress. While we could not rule out impact on cognitive load, it was not deemed a mediator in this study. Our findings signal that improvements in economic and psychological well-being among low-income consumers may aid to increase their demand for healthier processed foods.
