Sustainable urban mobility: An alternative for air pollution in the Guadalajara Metropolitan Area

José Antonio Olivares Mendoza Clemente Hernandez-Rodriguez Luz Alicia Jimenez Portugal (2023, [Artículo, Artículo])

The objective of this paper is to evaluate whether the low-carbon transport strategy (subway, rapid transit bus system -Macrobús-, trolleybus, and shared bicycles) implemented in the Guadalajara Metropolitan Area (AMG) from 2000 to 2019 improves air quality. Sustainable urban mobility is the movement of people in cities in a way that generates the least impact on the environment. We analyze three actions of government intervention in the same sense. This is the first study for Guadalajara, the third-largest city in Mexico. We use robust Newey-West estimators and endogenously model pollution disruptions using the Bai Perron approach. Our results suggest that this type of public transport reduces SO2, NO2, O3, and CO, though we find an increase in PM10. We also identified that when the service of the first line of the Bus Rapid Transit was consolidated CO, O3 and PM10 decreased. In addition, the improvement in the connectivity of the bus network with the subway means that only NO2 diminished. Finally, the entry into operation of the shared bicycle program reduced PM10, while increasing O3 and in SO2. In short, sustainable urban mobility is an alternative to making the transit of people efficient, while mitigating air pollution in the AMG.

Shopping centers at zmcm. The companies, location and production of a neoliberal urban space

Dante-Guillermo Celis-Galindo (2021, [Artículo, Artículo])

This work aims to analyze different aspects of shopping center at the Metropolitan Zone of Mexico City as location, opening year and developer company. Also it will identify diverse characteristics, economic and political phases in the country as well as the role of the development companies and shopping centers as a producers of a neoliberal urban space. This paper presents the way shopping centers importance has growth and how it had become in a neoliberal city characteristic; with this the characteristics of these urban works are visualized and related with their construction companies and local governments which has caused the transformation of the city. After conducting a census, with more than two hundred shopping centers, the study was delimited to those with the greatest significance by size, location and developer. At the beginning of the paper, the characteristics that shopping malls should have for the realization of this work are mentioned. In a first section an approach is made to the theoretical elements of the city and the shopping center and therefore identifying the developers that most  nfluence this process; the second section addresses the characteristics of places by location and the characteristics that urban planners have depending on the area where they are; the third section discusses the years of opening, the squares and relates to government administrations and the economic characteristics of the country; and finally, a tour of the urban regulations in Mexico City and its latest modifications is made.

A pre-pandemic study about recreational uses in the Mexico Park located at Mexico City (year 2017)

Ramiro Flores-Xolocotzi Sergio Ceballos (2022, [Artículo, Artículo])

A recreational study was carried out through surveys in the Parque México in Mexico City. For this, the relationship between visit patterns with socioeconomic information, uses and perceptions of visitors with 18 years old or older was analyzed. This research uses descriptive statistics and a non-linear canonical correlation analysis to analyze relationships between variables. An ordered probit regression was also performed to determine the variables that explain the frequency of recreational use. It was obtained that the Park mainly receives visitors with at least bachelor's degree (78.6%) and high incomes (more than 50% have a monthly family income higher than $10,000.00 pesos and 27.6% receive more than $30,000.00 per month). Considering the results, the conclusions are that although the highest percentage of the studied population comes from neighborhoods outside the Roma-Condesa Corridor: then the visitors who live in the Corridor and who have higher incomes, have weight in the description of the model. The results allow to conclude too, that higher income increases the frequency of use. It is also observed that the park is used during the Monday to Friday by more than 50% of the population of visitors and with a high percentage of use in the mornings.

The public-private confluence of interests between urban and real estate marketing. The case of the Mitikah Ciudad Viva project

ANA PAULA MONTES RUIZ (2021, [Artículo, Artículo])

The shift from a managerial to an entrepreneurial approach establishes a new form of urban governance based on a broader coalition of forces in which public-private partnerships have taken place. The Xoco-Mitikah urban conflict shows that the confluence of interests between the real estate and urban tourism industry embraces the common goal of designing an urban experience that makes the competitive advantages of Southern Mexico City profitable for both. Mitikah’s real estate marketing analysis showed that, through the promotion highlights of the South, the conflictive socio-territorial relationships that emerge along with the construction of real estate megaprojects are emotionally and affectively mediated.

Consideración de fuerzas de filtración en el análisis de estabilidad de taludes granulares

XIANGYUE LI LIU LUIS EMILIO RENDON DIAZ MIRON MARIA JOSELINA CLEMENCIA ESPINOZA AYALA (2010, [Artículo])

Para estudiar materiales porosos se presenta un modelo elastoplástico. Mediante dicho modelo es factible determinar las condiciones bajo las que sucede el colapso de taludes formados por materiales granulares saturados, sujetos a un campo de fuerzas de filtración en régimen estacionario. Los análisis de estabilidad de talud desarrollados en este trabajo, permiten calcular, con un adecuado nivel de precisión, el campo de flujo de agua y la condición de colapso de las masas de suelo bajo el flujo de agua y la carga interna, ambos generados por la gravedad.

Aprovechamiento de biosólidos y composta en el cultivo de haba (Vicia faba L.)

SOFIA ESPERANZA GARRIDO HOYOS MARIA GUADALUPE MARTIN DEL CAMPO SANCHEZ ROCIO VACA PAULIN JORGE ALBERTO LUGO DE LA FUENTE (2005, [Artículo])

La disposición final que se le puede dar a los biosólidos procedentes del tratamiento de aguas residuales municipales depende de sus características físico - químicas y microbiológicas. El contenido de

materia orgánica y su riqueza en elementos esenciales puede permitir que dichos biosólidos sean usados como fertilizantes agrícolas. El objetivo de este estudio fue determinar la acumulación de metales pesados en el suelo y en el cultivo de haba (Vicia faba L.), así como el

valor nutrimental de la semilla de haba, acondicionados con biosólidos y composta provenientes de una planta de tratamiento de aguas residuales del altiplano mexicano.
