Persistencia de las formas de vida campesina. Identidad y patrimonio agrícola de la Región de Los Llanos (Durango, México)

Mundo Agrario (2022)

María del Socorro Morales de Casas Marco Linares Luís Arturo Ávila Meléndez

El objetivo de esta investigación fue identificar los elementos del arreglo tecnológico y social que influyen en la persistencia de la forma de vida campesina en la región de Los Llanos, Durango. El método empleado fue la Teoría Fundamentada y como técnica la entrevista a profundidad con 21 agricultores en ocho comunidades. Resultaron dos categorías clave dentro del arreglo social y una dentro del tecnológico. Se concluye que los limitantes son las condiciones ambientales regionales, la política agraria, la falta de organización productiva y el rendimiento económico. Asimismo la persistencia es favorecida por el patrimonio agrícola y la identidad colectiva.

Espacios de vida y subjetividades de los jornaleros agrícolas: reglamentaciones morales en sociedades agroempresariales contemporáneas.

Agricultura Sociedad y Desarrollo (2014)

M. Rocío Echeverría-González Luís Arturo Ávila Meléndez Adela Miranda-Madrid

En este trabajo se explora la formación de espacios de vida precarios y la construcción de representaciones sociales y subjetividades de la población jornalera en México mediante el estudio de seis vecindades y diversos espacios públicos de Yurécuaro, Michoacán, entre septiembre de 2007 y marzo de 2010. En particular, se obtuvo información de las condiciones materiales y de la vida cotidiana en las viviendas y espacios públicos; de los procesos de asimilación de sufrimientos físicos y emocionales, y restricciones dramáticas de los proyectos de vida de los jornaleros. La investigación muestra cómo el mercado capitalista contribuye a crear subjetividades a las cuales les resulten menos significativas las alternativas colectivas que han surgido frente a los proyectos civilizatorios y desarrollistas, a pesar de su origen cultural comunitario, y de ocupar el lugar menos favorecido en el mercado laboral.

Biotic Integrity, Water Quality, and Landscape Characteristics of a Subtropical River

Water (2023)

Luis Fernando Gudiño-Sosa Rodrigo Moncayo‐Estrada Martha Alicia Velázquez Machuca Gustavo Cruz-Cárdenas Luís Arturo Ávila Meléndez

The integrity of rivers is affected by anthropogenic activities at different spatial scales, from basin and landscape levels to the direct effects on the river and aquatic life. Our objective was to study these effects on the subtropical La Pasión River, analyzing environmental, geomorphological, habitat and water quality, and macroinvertebrates. We sampled the dry season (March 2022) because the river presented stable conditions. We selected the most influential variables in each spatial scale and determined their relationship with the indexes of quality characteristics and aquatic life in the river using multivariate statistics. Most sites (≈65%) had medium water and suboptimal habitat quality status, meanwhile half the sites had regular biotic integrity status; without finding coincidence in the quality of the different indexes applied, all sites indicated a high gradient of degradation from the origin to the mouth of the river. The presence of some families (e.g., Culicidae, Chironomidae, Lumbriculidae) indicated organic matter contamination. The main variables that significantly classified the river quality and integrity structure were water flow, turbidity, habitat embeddedness, and sulfates (χ2 = 0.1145, p < 0.01). It is concluded that the affected sites received wastewater without prior treatment and presented physical barriers such as irrigation channels.

Geostatistical Modeling of Facies and Fractures of the San Juan Formation and Reservoir Modeling for Delineation of Orocual Field, Venezuela

SPE Annual Technical Conference and Exhibition (2000)

Róbert Porjesz Marielis Vargas Agostino Guerini Pascual Márquez Luís Arturo Ávila Meléndez

Abstract The Orocual field is located in northern Monagas State of Venezuela and is owned and operated by Petroleos de Venezuela, S.A. (PDVSA), the national oil company of Venezuela. This paper presents the results of the geological and geostatis-tical modeling aspects of an integrated study for the San Juan Reservoir in Orocual Field, Eastern Venezuela. The objective of this work was to establish a static model to be used in dynamic modeling to determine development potential, risk, and hydrocarbon reserves. Special interest exists in untested but highly prospective areas. A recently acquired 3-D seismic volume was integrated with a detailed core based sedimentology study used to define the depositional environment and facies connectivity. Based on this description, the San Juan Formation is subdivided into 3 major sedimentological units: Lower, Middle and Upper. A stochastic method was used to quantify model uncertainty. The fine grid geostatistical model was up-scaled to provide facies consistency for reservoir modeling. The prediction of heterogeneous fractured reservoir was added to the complexity. Numerical simulation was performed and will be discussed.

La extracción de recursos naturales y la protesta social en el Perú

Revista Andina de Estudios Políticos (2017)

José Manuel Mejía Luís Arturo Ávila Meléndez

Moises Arce's book, The extraction of natural resources and social protest in Peru (PUCP, 2015), is an important contribution to understanding the social protests in Peru today. Its objective is ambitious by offering a general reading of the factors that determine the dynamics of the protests and their impact on national politics. In this sense, the author inserts his work in two arenas of debate: one linked to efforts to identify the conditions in which the protests in Peru between 1980 and 2010 emerge - or more precisely, re-emerge4 (chap. 1-3) , and another relative to the political effects of the same (chap. 4-6).

Historical Delineation of Landscape Units Using Physical Geographic Characteristics and Land Use/Cover Change

Open Geosciences (2018)

Oswaldo Campos-Campos Gustavo Cruz-Cárdenas Roque Juan Carrasco Aquino Rodrigo Moncayo‐Estrada Martha Alicia Velázquez Machuca

Abstract Landscape units are conceived as a part of the territory that share similar physical and geographic characteristics. Their delineation can contribute to identify the physical and social dynamics that emerge in the spatial environment and to propose strategies of planning and management of the territory. The main objective was to make a historical delineation of landscape units in the Duero river basin that demonstrate the dynamics of changes in the territory, the description of the actors involved, and the affectations in the natural and social environment. We analyzed the vegetation change and urban growth from 1983 to 2014, incorporating climatic, edaphic, and topographic variables. A Principal Component Analysis was performed with the information and results were used in Maximum Likelihood procedure to define different clusters based on environmental characteristics. We defined five categories from the Landsat images. Results showed landscape units with homogeneous environmental characteristics and some differences in the units’ delineation were mainly influenced by political and socioeconomic factors. Temporally there was an increased tendency of landscape units, three in 1983, nine in 1990, 1995, 2000 and 2011, and eight in 2014. This increase resulted from territory fragmentation because of berries and avocado cultivars expansion over wooded area.

Sociabilidad restringida en aulas multiculturales con niños jornaleros itinerantes

Revista mexicana de investigación educativa/Revista mexicana de investigación educativa (2018)

Alfonso Zambrano Romero Luís Arturo Ávila Meléndez

espanolResumen: El objetivo de este trabajo es analizar la sociabilidad de la ninez migrante en espacios escolares de Yurecuaro, Michoacan, Mexico. Para ello, registramos interacciones e indagamos las relaciones de amistad reportadas por los ninos y sus padres. El modelo explicativo que retomamos ha implicado realizar una interpretacion de las evidencias etnograficas considerando las relaciones desiguales de grupos culturales en contacto. Identificamos indicios de que la sociabilidad de migrantes itinerantes en la escuela enfrenta obstaculos que limitan su potencial. Concluimos que destacar las relaciones desiguales, que al mismo tiempo son economicas, politicas y simbolicas, proporciona un panorama mas amplio de los retos de la educacion intercultural. EnglishAbstract: The objective of this study is to analyze the sociability of migrant children in schools in Yurecuaro, Michoacan, Mexico. To this end, we recorded interactions and researched the friendships reported by the children and their parents. The explanatory model we used has implied an interpretation of the ethnographic evidence, taking into account the unequal relationships of cultural groups in contact. We found indications that the sociability of migrant children at school faces obstacles that limit their potential. Our conclusion is that calling attention to unequal relationships, which at the same time are economic, political, and symbolic, provides a broader panorama of intercultural education.
