Surviving “la lucha” in Ciudad Juárez. An Anthropological reflection on the cuban community in Ciudad Juárez, México

Stephanie Morales Victor Vazquez (2021, [Artículo, Artículo])

The following article presents a brief anthropological and historical reflection based on the Cuban community in Ciudad Juárez, Chihuahua, México. Additionally, we discuss important historical aspects that have contributed to the development of the Cuban community in El Paso, TX-Ciudad Juárez, CH border, such as the migrant caravans that occurred between 2017-2019 and the migratory policies that have been put into effect. Furthermore, we present an ethnographic analysis on the migration experience of certain participants, placing an emphasis on created networks, and expanding on the concept of community through spatial solidarity and survival in Ciudad Juárez.

The spatial control of migrants on the Chihuahua border

EDGAR ABEL CASTRO (2023, [Artículo, Artículo])

This article tries to link the immigration policies of the United States and Mexico with the narrative developed by Michel Foucault. It shows how racism is the axis on which the State of biopower exercises its claims and its effects of power on bodies and on life. Thus, the current political rationality goes through the management of the living body of people, their health, and their spatiality. This principle extends to the homicidal function of the State. Two events that occurred on the Chihuahua border demonstrate this.

Contrasting spatial patterns in active-fire and fire-suppressed mediterranean climate old-growth mixed conifer forests

Danny L. Fry  (2014, [Artículo])

In Mediterranean environments in western North America, historic fire regimes in frequent-fire conifer forests are highly variable both temporally and spatially. This complexity influenced forest structure and spatial patterns, but some of this diversity has been lost due to anthropogenic disruption of ecosystem processes, including fire. Information from reference forest sites can help management efforts to restore forests conditions that may be more resilient to future changes in disturbance regimes and climate. In this study, we characterize tree spatial patterns using four-ha stem maps from four old-growth, Jeffrey pine-mixed conifer forests, two with active-fire regimes in northwestern Mexico and two that experienced fire exclusion in the southern Sierra Nevada. Most of the trees were in patches, averaging six to 11 trees per patch at 0.007 to 0.014 ha-1, and occupied 27-46% of the study areas. Average canopy gap sizes (0.04 ha) covering 11-20% of the area were not significantly different among sites. The putative main effects of fire exclusion were higher densities of single trees in smaller size classes, larger proportion of trees (≥56%) in large patches (≥10 trees), and decreases in spatial complexity. While a homogenization of forest structure has been a typical result from fire exclusion, some similarities in patch, single tree, and gap attributes were maintained at these sites. These within-stand descriptions provide spatially relevant benchmarks from which to manage for structural heterogeneity in frequent-fire forest types.

Empleo del software RStudio para la validación analítica Pb en suelo urbano

Eliany Nicado ALBA YADIRA CORRAL AVITIA Laura Elena Santana Contreras Jonatan Torres-Pérez Miroslava Quiñonez Martínez Juan Pedro Flores-Margez (2023, [Artículo, Artículo])

La validación de los métodos analíticos es un requisito importante en la práctica del análisis químico, por lo que cada vez que se desea realizar un control de calidad de una medición, es necesario llevarlo a cabo. La presente investigación tiene como objetivo validar analíticamente la determinación de Pb en suelo urbano por espectrometría de absorción atómica en horno de grafito (GF-AAS por sus siglas en inglés), ya que en un futuro se desea medir el impacto que pueden causar las deposiciones atmosféricas en los suelos, debido a las emisiones de material particulado de las ladrilleras artesanales de Ciudad Juárez, Chihuahua, México. En breve se obtuvo valores de alta calidad, ya que se usaron técnicas y análisis estadísticos más robustos y en menos tiempo que una validación convencional.

Surviving “Los Sures”: An anthropological reflection on the Nuyoricans lived experiences in South Williamsburg, Brooklyn and the current urban context of gentrification in New York City

Victor Vazquez Ashley McAfee (2021, [Artículo, Artículo])

The following article presents an anthropological and historical reflection on the Puerto Rican inner-city neighborhood better known as “Los Sures” in South Williamsburg, Brooklyn, New York City (nyc). The analysis will explore the contemporary academic discussion regarding the following concepts: poverty, the welfare State, the discourse surrounding welfare recipient’s culture, inner-city living conditions, and the current context of gentrification. Methodologically, the article presents an ethnographic reflection based on fieldwork experiences and interviews conducted on residents of the previous “Los Sures” and still living in nyc. Finally, we present a critical reflection on the poverty, welfare State policy, and shed light on the difficulties faced by Puerto Rican migrants and their struggle to preserve the Puerto Rican legacy in the now nyc and gentrified “Los Sures”.

The new proletariat of the north at Ciudad Juarez: Current trends.

Nolberto Tlacaelel Acosta Pérez (2022, [Artículo, Artículo])

The arrival of the nowadays renamed Manufacturing, Maquiladora and Export Service Industry brought within the formation of a new labor subject in the region: the new proletariat of the north. The proposal of the present article is to identify and describe the specific traits of this working class sub-fraction, by a reevaluation of its meaning, the most relevant socioeconomic indicators which serve to understand it, the political organization chapters that it has undertaken in the past years, and its most characteristic cultural attributes.

Remedies for the Inconsistences in the Times of Execution of the Unsorted Database Search Algorithm within the Wave Approach

Manuel Ávila Aoki José Benito Elizalde Salas (2017, [Artículo])

The typical semiclassical wave version of the unsorted database search algorithm based on a system of coupled simple harmonic oscillators does not consider an important ingredient of Grovers original algorithm as it is quantum entanglement. The role of entanglement in the wave version of the unsorted database search algorithm is explored and contradictions with the time of execution of Grovers algorithm are found. We remedy the contradictions by employing two arguments, one of them qualitative and the other quantitative. For the qualitative argument we employ the probabilistic nature of a legitimate quantum algorithm and remedy the above inconsistence. Within the quantitative argument we identify a parameter in the wave version of the unsorted database search algorithm which is related to entanglement. The contradiction with the time of execution of Grovers algorithm is solved by choosing an appropriate values of such a parameter which incorporates entanglement to the wave version of the unsorted database search algorithm. The utility of the present arguments are evident if the wave version of the unsorted data base search algorithm is experimentally implemented through a system of N quantum dots with a harmonic oscillator potential as a confinement potential for each of the quantum dots. Each of the above N vibrating quantum dots must be coupled to an extra single vibrating quantum dot which entangles to all of them. In order to obtain optimal results, the coupling constants of the mentioned quantum dots should be adjusted in the way described in the present work.
