Distance learning for farmers: Experience during the pandemic

Andrea Gardeazabal (2023, [Documento de trabajo])

In response to the COVID-19 pandemic's disruption of farmer training—a crucial component for enhancing the resilience and livelihoods of smallholder farmers—CIMMYT innovated educational solutions to sustain capacity building in agri-food systems. Addressing the challenges of limited mobile device access, poor internet connectivity, and digital illiteracy, CIMMYT implemented two pilot projects in Mexico. These projects facilitated distance learning for adult farmers in rural areas, employing both internet-based and non-internet methods. The non-internet approach utilized traditional media like print, while the internet-based approach leveraged WhatsApp for educational content delivery. Building on these experiences, CIMMYT expanded its offerings by creating micro -courses delivered through WhatsApp, hosted on the Co-LAB's new Learning Network platform, specifically targeting farmers. This paper delves into the various strategies, methods, and techniques adopted, documenting the learning outcomes, results, and key conclusions drawn from these innovative training initiatives.

Universal fixation system for pad printing of plastic parts

JOSE ALEJANDRO FERNANDEZ RAMIREZ (2023, [Artículo])

Pad printing is used in automotive, medical, electrical and other industries, employing diverse materials to transfer a 2D image onto a 3D object with different sizes and geometries. This work presents a universal fixation system for pad printing of plastic parts (UFSP4) in response to the needs of small companies that cannot afford to invest in the latest technological advances. The UFSP4 comprises two main subsystems: a mechanical support system (i.e., support structure, jig matrix and braking system) and a control system (i.e., an electronic system and an electric-hydraulic system). A relevant feature is the combination of a jig matrix and jig pins to fixate complex workpieces with different sizes. Using finite element analysis (FEA), in the mesh convergence, the total displacement converges to 0.00028781 m after 12,000 elements. The maximum equivalent stress value is 1.22 MPa for the polycarbonate plate in compliance with the safety factor. In a functionality test of the prototype performed in a production environment for one hour, the jigs fixed by the plate did not loosen, maintaining the satisfactory operation of the device. This is consistent with the displacement distribution of the creep analysis and shows the absence of the creep phenomenon. Based on FEA that underpinned the structural health computation of the braking system, the prototype was designed and built, seeking to ensure a reliable and safe device to fixate plastic parts, showing portability, low-cost maintenance and adaptability to the requirements of pad printing of automotive plastic parts.

Tutoring to novel teachers. A fragment of skylight from the border of Ciudad Juarez

Silvia Gabriela Alvídrez Minora (2022, [Artículo, Artículo])

This article describes and interprets the tutoring of novice teachers in a preschool area of ​​Ciudad Juarez. The study is situated in the interpretive paradigm; It makes use of the ethnographic method and research techniques such as participant observation and interview. The partial results show that tutoring is considered an important process for the insertion and professionalization of new teachers; however, it is mentioned that this enriching relationship is only possible when there is communication between all the people involved in the tutoring, in addition to being open to peer learning.

On-farm storage loss estimates of maize in Kenya using community survey methods

Hugo De Groote Anani Bruce (2023, [Artículo])

Maize is the most important staple in sub-Saharan Africa (SSA), with highly seasonal production. High storage losses affect food security, but good estimations are lacking. A new method using focus group discussions (FGDs) was tested with 121 communities (1439 farmers, 52% women) in Kenya's six maize-growing zones, to estimate the maize losses to storage pests and analyze farmer practices. As control strategies, half of the farmers used chemical pesticides (49%), while hermetic bags (16%) and botanicals (15%) were also popular. Relative loss from weevils in the long rains was estimated at 23%, in the short rains 18%, and annually 21%. Fewer farmers were affected by the larger grain borer (LGB) than by maize weevils: 42% in the long rainy season and 32% in the short rainy season; losses from LGB were also smaller: 19% in the long season, 17% in the short season, and 18% over the year. Total storage loss, from both species combined, was estimated at 36%, or 671,000 tonnes per year. The greatest losses occur in the humid areas, especially the moist mid-altitudes (56%), and with smaller loss in the drylands (20–23%). Extrapolating the point data and overlaying with the maize production map shows the geographic distribution of the losses, with the most important area found around Lake Victoria. FGDs provide convenient and cheap tools to estimate storage losses in representative communities, but a total loss estimate of 36% is higher than is found in other studies, so its accuracy and framing effects need to be assessed. We conclude that storage pests remain a major problem, especially in western Kenya, and that the use of environmentally friendly technologies such as hermetic storage and botanicals needs more attention, both by the public extension service and private agrodealers.

Generalized Neophobia: concept, theoretical model and measurement

Arturo Barraza Macías (2023, [Artículo, Artículo])

Objective: To build and validate the generalized neophobia scale and establish its prevalence and sociodemographic profile of the participants. Method: an instrumental and correlational study was carried out by applying the generalized neophobia scale to 517 people. Results: the scale has a reliability level that ranges between .79 and .88, the exploratory factor analysis reports a single factor that explains 69.29% of the total variance and the confirmatory factor analysis reports a perfect fit model; the prevalence in the surveyed population was 13.5% and it is women and younger people who report a higher level of neophobia. Conclusions: the theoretical-conceptual contributions of this research can be assessed as consistent and its empirical contribution can be considered as indicative since its main limitation is the selection of the sample determined by accessibility and availability.

La literatura de no ficción en México: Asesinato, de Vicente Leñero

Abordar el tema de literatura de no ficción resulta relevante tanto para el estudio de la literatura como para el del periodismo, ya que es dentro de estas dos áreas donde este género encuentra sus fronteras. Existen diversos artículos e investigaciones que se han encargado de estudiar el tema, en la mayoría de los casos estos estudios parten de las obras fundacionales de la no ficción. Entre ellas se encuentran: Operación Masacre (1957) de Rodolfo Walsh, A sangre fría (1966) de Truman Capote y Los ejércitos de la noche (1968) de Norman Mailer. Sin embargo, son pocas las investigaciones que se han encargado del estudió de la no ficción en México, su surgimiento y obras fundacionales. Por este motivo, en la siguiente investigación se analizará el cuarto capítulo de la novela Asesinato (1985) del escritor Vicente Leñero. En esta novela es donde se pueden observar con mayor claridad los elementos propios de la no ficción, así como el estilo dado por Leñero a este género. Elementos que lo vuelven uno de los fundadores de este género en la narrativa mexicana del siglo XX. Para sustentar teóricamente el análisis de este texto se retomarán las ideas expuestas por Tom Wolf y Jonh Hollowell, respecto al tema del llamado “Nuevo periodismo” o Literatura de no ficción. Finalmente, para entender el término “nuevo periodismo” en la narrativa mexicana es necesario revisar de forma general la evolución del periodismo en México, ya que éste sentó las bases para la creación de la no ficción. Son las técnicas de representación de la no ficción las que permiten observar la evolución del periodismo. La información ya no está delimitada a la transmisión llana del hecho. Ahora la voz de los sujetos implicados, así como la del periodista son tan importantes como la acción misma. Lo imparcial adquiere un tono personal.
