Síncrono / asíncrono. Convergencia y alternancia en la enseñanza futura del diseño

Francisco Gerardo Toledo Ramirez (2023, [Capítulo de libro])

La cuarentena sanitaria de los últimos dos años (COVID-19) obligó a “rediseñar”, “digitalizar” o “virtualizar” nuestros cursos y estilos de enseñanza en tiempo récord para “adaptarlas” al “formato virtual a distancia” (online). La profusión de comillas en las líneas anteriores tiene la intención de señalar el carácter incierto o erróneo que ciertos términos-fetiche adquirieron en el proceso. Es importante desmitificar esas figuras de la expresión que se elevaron casi al nivel de pseudo-epistemes (presuntamente novedosas) para la enseñanza del Diseño. Ese tema lo abordo con mayor amplitud en una nueva investigación, recientemente registrada en la UAM. En este texto esbozo (en forma algo lúdica) pero seria y breve a la vez, la conveniencia de tal desmitificación y avanzo en el delineamiento de un modelo de la alternancia y convergencia de recursos pedagógico-didácticos síncronos y asíncronos, mediante la tecnología-red digital, como un elemento estratégico para la educación futura en Diseño.

The health quarantine of the last 2 years (COVID-19) forced us to “redesign”, “digitize” or “virtualize” our courses and teaching styles in record time to “adapt” them to the “virtual format” “at a distance” (online). The profusion of quotation marks in the previous lines is intended to indicate the uncertain or erroneous character that certain fetish-terms acquired in the process. It is important to demystify those figures of expression that have risen almost to the level of pseudo-epistemes (presumably novel) for teaching design. I address this topic more fully in a new investigation, recently registered at the UAM. In this text I outline (in a somewhat playful way) but serious and brief at the same time, the convenience of such “demystification” and I advance in the outline of a model of alternation and convergence of synchronous and asynchronous pedagogical-didactic resources, through technology. -digital network, as a strategic element for future design education.

Teacher training in the state of Chihuahua: Between the health challenge and teacher resilience

Evangelina Cervantes Holguín Pavel Roel Gutiérrez Sandoval Cely Celene Ronquillo Chávez (2023, [Artículo, Artículo])

The article proposes to recover the response of the Teacher Training and Updating Institutions in the state of Chihuahua regarding the various challenges imposed by the Coronavirus Disease (COVID-19). The qualitative exercise analyzes the experience of 10 institutions based on the voice of their students, teachers, and principals regarding changes in academic, administrative, and organizational processes. It is concluded that the pandemic has affected each institution in different ways and with diverse intensity. Despite the achievements, the experience analyzed reveals the relative success of the using virtual platforms in the face of three basic conditions: connectivity, technological competencies, and socio-emotional skills of the teaching staff. It highlights the importance of implementing tutoring, resilience, or awareness actions of teachers and students' needs, feelings, and sufferings. It is opportune to recover the experiences of other institutions and to question especially students, thesis students and graduates.

Una articulación fundamental: la emancipación

Nicolás Amoroso Boelcke (2023, [Capítulo de libro])

El concepto, la circunstancia de la enseñanza que aquí abordaremos, tiene el propósito de restituir ciertas situaciones que corresponden al propio ejercicio de la instrucción y a aquellas otras que hablan del acontecer, por ello el trabajo. Tiene las variables tanto de la experiencia real como de las otras sobre las que se han escrito, una de ellas, al final, plantea una situación paradójica que se refiere a la del maestro ignorante que, básicamente, tiene como propósito mostrar que el conocimiento es algo que está en el alumno y que el docente debe limitarse a tratar de que aflore y se exprese de la mejor manera posible. Nos habla de la independencia y de las características que puede tener una educación rigurosa y rígida, en contraposición con una más flexible. Lo mismo sucede con el pensamiento desde nuestra América, de la educación dependiente a una educación libertaria.

The concept, the circumstance of the teaching that we will address here has the purpose of restoring certain situations that correspond to the exercise itself as those others that speak of the happening for it the work. It has the variables of real experience as of the others about which they have been written, one of them, in the end, poses a paradoxical situation that refers to that of the ignorant teacher that, basically, has the purpose of showing that knowledge is something that is in the student and that the teacher must limit himself to trying to bring it out and express itself in the best possible way. It tells us about independence and the characteristics that a rigorous and rigid education can have with a more flexible one and the same happens with the thought from our America, from dependent education to a libertarian education.

Big data, small explanatory and predictive power: Lessons from random forest modeling of on-farm yield variability and implications for data-driven agronomy

Martin van Ittersum (2023, [Artículo])

Context: Collection and analysis of large volumes of on-farm production data are widely seen as key to understanding yield variability among farmers and improving resource-use efficiency. Objective: The aim of this study was to assess the performance of statistical and machine learning methods to explain and predict crop yield across thousands of farmers’ fields in contrasting farming systems worldwide. Methods: A large database of 10,940 field-year combinations from three countries in different stages of agricultural intensification was analyzed. Random effects models were used to partition crop yield variability and random forest models were used to explain and predict crop yield within a cross-validation scheme with data re-sampling over space and time. Results: Yield variability in relative terms was smallest for wheat and barley in the Netherlands and for wheat in Ethiopia, intermediate for rice in the Philippines, and greatest for maize in Ethiopia. Random forest models comprising a total of 87 variables explained a maximum of 65 % of cereal yield variability in the Netherlands and less than 45 % of cereal yield variability in Ethiopia and in the Philippines. Crop management related variables were important to explain and predict cereal yields in Ethiopia, while predictive (i.e., known before the growing season) climatic variables and explanatory (i.e., known during or after the growing season) climatic variables were most important to explain and predict cereal yield variability in the Philippines and in the Netherlands, respectively. Finally, model cross-validation for regions or years not seen during model training reduced the R2 considerably for most crop x country combinations, while for wheat in the Netherlands this was model dependent. Conclusion: Big data from farmers’ fields is useful to explain on-farm yield variability to some extent, but not to predict it across time and space. Significance: The results call for moderate expectations towards big data and machine learning in agronomic studies, particularly for smallholder farms in the tropics where model performance was poorest independently of the variables considered and the cross-validation scheme used.

Monitoreo con drones en gráficas con viento dinámico

Jovanni Manuel López Elisea (2024, [Tesis de maestría])

108 páginas. Maestría en Optimización.

Dada una gráfica completa no dirigida, se desea recorrer un subconjunto de sus aristas usando una flotilla de drones. Los drones tienen baterías limitadas que pueden recargarse al regresar a la base y, en principio, el tiempo para recorrer una arista está en función de la distancia entre sus vértices. Sin embargo, ante la presencia de viento el tiempo de recorrer una arista puede depender del sentido en el que se haga. La dificultad del problema aumenta si además la intensidad del viento puede variar de un instante a otro. En esta tesis se aborda el problema anteriormente descrito para el caso particular en el que los vértices son puntos en el plano, el impacto del viento en los tiempos de recorrido de las aristas está relativamente acotado y el subconjunto de las aristas a recorrer inducen un árbol que abarca todos los vértices excepto la base de los drones. Dado que los drones operan simultáneamente y pueden recorrer distintas partes de la gráfica de manera independiente, se desea minimizar el tiempo que emplea el dron con el recorrido más tardado. Esta tesis presenta un modelo matemático para resolver el problema de manera exacta, así como tres heurísticas diferentes para obtener buenas soluciones factibles. La primera de estas heurísticas transforma una solución sin viento y sin batería en una solución con viento y batería. La segunda heurística es un algoritmo glotón sin comunicación entre los drones y la última heurística también es un algoritmo glotón, pero con comunicación entre los drones. Aunque el problema abordado resulta ser lo suficientemente difícil como para que su resolución exacta sea inviable en la práctica, las heurísticas diseñadas son fáciles de implementar y obtuvieron resultados razonables en un tiempo corto de cómputo.

Propaganda against Mexican women married to Chinese immigrants in Chihuahua 1920-1940

Vladimir Alejandro Armendáriz Romero Jesús Adolfo Trujillo Holguín (2023, [Artículo, Artículo])

At the turn of the 20th century and at the beginning of the new revolutionary government stage in Mexico, the press was an effective way to disseminate propaganda for the nationalist ideology of the State. An important part of this diffusion covered the question of the racial constitution of the mexicans, which led to the need to convince the public that it was important to determine controls over women and with whom they married since they were responsible for the reproduction of the Mexican race. Therefore, a mixture of races considered undesirable, such as the Chinese, was detestable. This propaganda occurred in the context of national anti-Chinese and anti-Jewish campaigns in which they wanted to expel these foreigners on the pretext that their presence and mixing with them would result in degeneration. In Chihuahua there are indications of this propaganda, but also that women married to Chinese resisted this campaign against their families.

Hymenopteran parasitoid complex and fall armyworm: a case study in eastern India

Tapamay Dhar PRATEEK MADHAB BHATTACHARYA Mahesh Gathala Alison Laing (2024, [Artículo])

Fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) has significantly affected maize crop yields, production efficiency, and farmers’ incomes in the Indian Eastern Gangetic Plains region since it was first observed in India in 2018. A lack of awareness by maize growers of the appropriate selection, method, and timing of insecticide application not only creates a barrier to sustainable FAW control but also contributes to increased environmental pollution, reduced human health and increased production costs. We demonstrated that FAW inflicted the most damage in early whorl growth stage of maize, regardless of whether chemical insecticides were applied. FAW egg masses and larvae collected from maize fields in which no insecticides had been sprayed showed high parasitism rates by parasitoid wasps; in contrast fields that had been sprayed had much lower rates of parasitism on FAW. Ten hymenopteran parasitoids were observed in maize fields across the study region, suggesting a diversity of natural methods to suppress FAW in maize at different growth stages. These included two FAW egg parasitoids and eight FAW larval parasitoids. Microplitis manilae Ashmead was the most abundant FAW larval parasitoid species, and Telenomus cf. remus was the dominant FAW egg parasitoid species. Endemic FAW parasitoids such as those observed in this study have great potential as part of a sustainable, cost-effective agroecological management strategy, which can be integrated with other methods to achieve effective control of FAW.
