Risk, Covid-19 and hospital care in Mexico City: Are we moving toward a new medical practice?

Rubén Muñoz (2023, [Artículo, Artículo])

Covid-19 pandemic has entailed new challenges for health care in the Mexican public health sector, producing changes in clinical practices that are now handling patients infected with covid-19 and also outpatient consultations at tertiary-level care hospitals. Some of these challenges are related to the perception of risk held by physicians regarding the possibility of contracting or transmitting covid-19 during their work,and to the management of risk from the standpoint of biomedical organizational culture linked to the material and symbolic conditions of public health services predating the pandemic. We analyze these issues from a anthropological research based on in-depth interviews to physicians that work with covid-19 patients at “Covid-19 hospitals” or “hybrid hospitals” in Mexico City. Covid-19 has arrived in social relations and perceptions of risk in the arena of health care and involves knowing and transforming some structural and symbolic conditions, resignified with the pandemic, for proper medical care.

Effect of Nitrogen, Phosphorus and Potassium on regional organic substrates in Agave salmiana production in Huichapan, Hidalgo, Mexico

EMILIO RAYMUNDO MORALES MALDONADO MONICA GUTIERREZ ROJAS RAMON JAIME HOLGUIN PEÑA Daniel Ruiz-Juárez Jorge Luis Vega Chávez Ana Cristina Reyes Godoy (2022, [Artículo])

"Mexico has 159 species of Agave spp. In the agri-food industry stand out are Agave tequilana, A. angustifolia, and A. salmiana. A limitation to producing maguey seedlings is the low availability of organic substrates that favor plant adaptation in the field. The objective was to evaluate the effect of nitrogen (N), phosphorus (P) and potassium (K) found in substrates in response to vegetative and root growth of A. salmiana in agricultural areas of Huichapan, Hidalgo, Mexico. The treatment consisted of earthworm humus (EH) and leaf compost (LC) substrates with materials from the region with different percentages of EH (100, 75, 50%), LC (5, 10%), and sand (20, 40%). The treatments were applied with 14 random replications in two phases in seeds and 40-day-seedlings. The variables evaluated were NPK amount and pH in substrates. The physiological variables measured were plant height, leaf number, stem diameter, root length, and volume. Significant differences (P≤0.05) were observed in seedling physiology due to the effect of the treatment. The best agronomic responses (plant growth and root length/weight) of Agave seedlings were T5 (75% earthworm humus + 20% sand + 5% leaf-soil) and T6 (50% earthworm humus + 40% sand + 10% leaf-soil); in both treatments, the NPK percentages were different from the control (Haplic Phaeozem soil) group. The final concentration of NPK in T6 was N = 0.04%, P = 398.13 mg Kg-1 and K = 11.88 meq 100g-1 . The results infer that NPK availability in soil and progressive acidification (initial pH = 8.6, final pH = 7.4) of the substrate can favorably influence the plant response. The interactions between NPK availability in the substrate and their use for a better response in maguey seedling adaptability open up new lines of research on the productive systems in the región of Huichapan, Hidalgo, Mexico."

Voter´´´'s dilemma between honest and competent candidates in the 2018 elections in Mexico and Brazil

José Daniel Sousa Oliva (2023, [Artículo, Artículo])

This article is dedicated to understanding and explaining the electoral dilemma “Dishonest, but competent” and “Honest, but incompetent” in the elections of legislators, governors and municipal presidents in 2018 in Mexico and Brazil. The research questions that guided the investigation are: Why are there voters in Mexico and Brazil who vote for “dishonest” candidates? And how do the voters of those countries decide their vote in the face of this dilemma? The theoretical approach of this work is Social Psychology through two analytical tools: the Funnel of Causality and the Tripartite Model of Attitudes. The methodology is mixed, quantitative and qualitative, using statistical models with data from the international surveys World Values Survey and Comparative Studies of Electoral Systems, as well as the application of Focus Groups in the distance modality. In this way, four categories of voter are proposed: moralist, moralist-moderate, pragmatic-moderate and pragmatic. The arguments of this work are: first, that regardless of cultural differences, there is an “affective voter” “non-rational” who makes decisions based on emotions and intuition, demonstrating that the affective components of attitudes are more relevant than the cognitive ones in electoral choice; second, that voting for “dishonest” candidates is determined under a greater influence of “short-term factors” such as candidate characteristics and short-term events rather than “long-term factors” such as party loyalties and ideology.

Diseño y activismo artístico

Olivia Fragoso-Susunaga (2023, [Capítulo de libro])

En el 2015, las Naciones Unidas proponen una serie de objetivos dirigidos a convocar a los habitantes del mundo a realizar acciones orientadas a acabar con la pobreza, mejorar las condiciones del planeta y lograr que, para el 2030, todas las personas puedan gozar de paz y bienestar. A estos objetivos se les conoce como los Objetivos de Desarrollo Sostenible (ODS). La educación superior juega un papel fundamental en el logro de los ODS. La UAM y, en el caso que nos compete, el CyAD están llamados a colaborar en esta tarea que nos involucra a todos y todas quienes formamos la comunidad universitaria. Este trabajo es una reflexión sobre la importancia que tiene la formación en activismo artístico en la educación del diseño para el logro de los ODS. Se propone que enfatizar el vínculo entre el diseño y el activismo artístico es parte de un escenario futuro indiscutiblemente necesario en el currículo de licenciatura en el CyAD.

In 2015, the United Nations proposed a series of goals aimed at calling on the world’s inhabitants to take action to end poverty, improve the conditions of the planet and ensure that by 2030 all people can enjoy peace and well-being. These goals are known as the Sustainable Development Goals (SDGs). Higher education plays a fundamental role in the achievement of the SDGs, the UAM and, in the case that concerns us, the CyAD are called to collaborate in this task that involves all of us who form the university community. This work is a reflection on the importance of training in artistic activism in design education for the achievement of the SDGs. It is proposed that emphasizing the link between design and art activism is part of an indisputably necessary future scenario in the undergraduate curriculum at CyAD.

Phylogenetic relationships of Pseudo-nitzschia subpacifica (Bacillariophyceae) from the Mexican Pacific, and its production of domoic acid in culture

Sonia Quijano (2020, [Artículo])

Pseudo-nitzschia is a cosmopolitan genus, some species of which can produce domoic acid (DA), a neurotoxin responsible for the Amnesic Shellfish Poisoning (ASP). In this study, we identified P. subpacifica for the first time in Todos Santos Bay and Manzanillo Bay, in the Mexican Pacific using SEM and molecular methods. Isolates from Todos Santos Bay were cultivated under conditions of phosphate sufficiency and deficiency at 16°C and 22°C to evaluate the production of DA. This toxin was detected in the particulate (DAp) and dissolved (DAd) fractions of the cultures during the exponential and stationary phases of growth of the cultures. The highest DA concentration was detected during the exponential phase grown in cells maintained in P-deficient medium at 16°C (1.14 ± 0.08 ng mL-1 DAd and 4.71 ± 1.11 × 10−5 ng cell-1 of DAp). In P-sufficient cultures DA was higher in cells maintained at 16°C (0.25 ± 0.05 ng mL-1 DAd and 9.41 ± 1.23 × 10−7 ng cell-1 of DAp) than in cells cultured at 22°C. Therefore, we confirm that P. subpacifica can produce DA, especially under P-limited conditions that could be associated with extraordinary oceanographic events such as the 2013–2016 "Blob" in the northeastern Pacific Ocean. This event altered local oceanographic conditions and possibly generated the presence of potential harmful species in areas with economic importance on the Mexican Pacific coast. © 2020 Quijano-Scheggia et al.
