En la actualidad, la ansiedad representa uno de los mayores y más silenciosos problemas de la sociedad. Del mismo modo, las infancias y las adolescencias son una población que se ve afectada en gran medida por estos trastornos. En definitiva, estas es una población con una problemática apremiante de considerar, observar y trabajar. Por tal razón, resulta fundamental generar herramientas y estrategias que permitan a niños, niñas y adolescentes identificar y regular sus emociones de manera efectiva. Aprender a identificar las emociones es algo de suma importancia no solo dentro del proceso terapéutico, sino en la vida diaria del infante. En primer lugar, el hecho de reconocer y expresar emociones contribuye a canalizar la ansiedad. De igual forma, esto les ayuda a aprender a enfrentar los problemas de la vida diaria de una manera adecuada; por lo tanto, lo anterior se estima como un beneficio no solo en la infancia, sino también en la edad adulta. Asimismo, un correcto manejo emocional les permite incrementar la percepción de control sobre los sucesos que viven. Igualmente, esto refuerza su habilidad para empatizar, resolver conflictos y llegar a acuerdos, lo que mejora su forma de relacionarse con otras personas. En suma, son diferentes beneficios que se otorgarían al infante al aprender a conocer, identificar y expresar sus emociones. No obstante, estas aportaciones pueden ser mayores si se realizan a través de elementos lúdicos. Para empezar, la recreación es una acción nata y cotidiana en los infantes. El uso de fantasía, el juego simbólico y la imaginación son actividades naturales del desarrollo en el juego de los infantes (Schaefer, 2012). De igual manera, cuando las y los menores juegan, aprenden a tolerar la frustración, a regular sus emociones y a destacar en una tarea que es innata (Schaefer, 2012). En esa medida, el juego es quizá el medio más poderoso y apropiado para el desarrollo en el cual las y los menores pueden construir relaciones con los adultos, desarrollar el pensamiento causal, procesar las experiencias estresantes y aprender habilidades sociales (Chaloner, 2001). Por tal motivo, la propuesta para apoyar el proceso terapéutico se efectúa por medio de elementos lúdicos que permitan a los infantes identificar y expresar emociones a través del juego. Por tal motivo el objetivo de este trabajo es diseñar elementos lúdicos que apoyen a los niños de 6 a 8 años diagnosticados con ansiedad que se encuentren en tratamiento psicológico de la teoría cognitivo-conductual en la CDMX y área metropolitana con el fin de que puedan conocer, identificar y expresar sus emociones.

Los seres alados y solares del arte maya en el Norte de Yucatán

Rubén Morante (2023, [Capítulo de libro])

En nuestro trabajo de campo en el norte de Yucatán estudiamos la iconografía de sitios como Chichén Itzá, Ek Balam y Mayapán. En ellos observamos esculturas con gran calidad artística de seres humanos que portan alas y que, por ello, se presentan como seres celestes relacionados con deidades del panteón maya de los periodos Clásico tardío, Clásico terminal y Posclásico temprano. Para esta investigación partimos de un breve contexto etnohistórico, geográfico y arqueológico de otros sitios mayas, del centro y oriente de México, incluyendo imágenes de códices y pinturas que nos hablan del posible significado que las plumas, las alas y las aves tuvieron en Mesoamérica. Procedimos al análisis de las figuras aladas que se presentan en relación con importantes edificios de sitios del norte de Yucatán. La advocación solar que sugieren parece haber sido común y en esta zona, no sólo hablan de los grandes artistas que los esculpieron, sino de un sistema de creencias que pudo emanar de tradiciones mayas muy tempranas, que en el siglo IX d.C. se manifiesta de manera clara mediante un estilo depurado, una maestría técnica y una alta sensibilidad estética.

In our field work in northern Yucatán we studied the iconography of sites such as Chichén Itzá, Ek Balam, and Mayapán. There we saw great artistic quality sculptures of human beings that carry wings, and because of that we think that represented celestial beings related to deities of the Mayan pantheon of Late Classic, Terminal Classic and Early Postclassic periods. In our research we started with reviews of ethnohistorical, geographical and archaeological contexts in other Mayan sites, from central and eastern Mexico, including images from codices and paintings that tell us about the possible meaning of feathers, wings and birds in Mesoamerica. We proceeded analyze winged figures presented in relation to important buildings in northern Yucatán sites. Solar evocation suggested probably was common in this area and, sculptures not only speak about belief systems that could emanate from very early Mayan traditions, but also speak about great artists, that in 9th century AD. clearly manifested it through a refined style, technical mastery and high aesthetic sensitivity.

Modeling the growth, yield and N dynamics of wheat for decoding the tillage and nitrogen nexus in 8-years long-term conservation agriculture based maize-wheat system

C.M. Parihar Dipaka Ranjan Sena Prakash Chand Ghasal Shankar Lal Jat Yashpal Singh Saharawat Mahesh Gathala Upendra Singh Hari Sankar Nayak (2024, [Artículo])

Context: Agricultural field experiments are costly and time-consuming, and their site-specific nature limits their ability to capture spatial and temporal variability. This hinders the transfer of crop management information across different locations, impeding effective agricultural decision-making. Further, accurate estimates of the benefits and risks of alternative crop and nutrient management options are crucial for effective decision-making in agriculture. Objective: The objective of this study was to utilize the Crop Environment Resource Synthesis CERES-Wheat model to simulate crop growth, yield, and nitrogen dynamics in a long-term conservation agriculture (CA) based wheat system. The study aimed to calibrate the model using data from a field experiment conducted during the 2019-20-2020-21 growing seasons and evaluation it with independent data from the year 2021–22. Method: Crop simulation models, such as the Crop Environment Resource Synthesis CERES-Wheat (DSSAT v 4.8), may provide valuable insights into crop growth and nitrogen dynamics, enabling decision makers to understand and manage production risk more effectively. Therefore, the present study employed the CERES-Wheat (DSSAT v 4.8) model and calibrated it using field data, including plant phenological phases, leaf area index, aboveground biomass, and grain yield from the 2019-20-2020-21 growing seasons. An independent dataset from the year 2021–22 was used for model evaluation. The model was used to investigate the relationship between growing degree days (GDD), temperature, nitrate and ammonical concentration in soil, and nitrogen uptake by the crop. Additionally, the study explored the impact of contrasting tillage practices and fertilizer nitrogen management options on wheat yields. The experimental site is situated at ICAR-Indian Agricultural Research Institute (IARI), New Delhi, representing Indian Trans-Gangetic Plains Zone (28o 40’N latitude, 77o 11’E longitude and an altitude of 228 m above sea level). The treatments consist of four nitrogen management options, viz., N0 (zero nitrogen), N150 (150 kg N ha−1 through urea), GS (Green seeker based urea application) and USG (urea super granules @150 kg N ha−1) in two contrasting tillage systems, i.e., CA-based zero tillage (ZT) and conventional tillage (CT). Result: The outcomes exhibited favorable agreement between the model’s simulations and the observed data for crop phenology (With less than 2 days variation in 50% onset of flowering), grain and biomass yield (Root mean square error; RMSE 336 kg ha−1 and 649 kg ha−1, respectively), and leaf area index (LAI) (RMSE 0.28 & normalized RMSE; nRMSE 6.69%). The model effectively captured the nitrate-N (NO3−-N) dynamics in the soil profile, exhibiting a remarkable concordance with observed data, as evident from its low RMSE = 12.39 kg ha−1 and nRMSE = 13.69%. Moreover, as it successfully simulated the N balance in the production system, the nitrate leaching and ammonia volatilization pattern as described by the model are highly useful to understand these critical phenomena under both conventional tillage (CT) and CA-based Zero Tillage (ZT) treatments. Conclusion: The study concludes that the DSSAT-CERES-Wheat model has significant potential to assess the impacts of tillage and nitrogen management practices on crop growth, yield, and soil nitrogen dynamics in the western Indo-Gangetic Plains (IGP) region. By providing reliable forecasts within the growing season, this modeling approach can facilitate better planning and more efficient resource management. Future implications: The successful implementation of the DSSAT-CERES-Wheat model in this study highlights its applicability in assessing crop performance and soil dynamics. Future research should focus on expanding the model’s capabilities by reducing its sensitivity to initial soil nitrogen levels to refine its predictions further. Moreover, the model’s integration with decision support systems and real-time data can enhance its usefulness in aiding agricultural decision-making and supporting sustainable crop management practices.

Evaluación del uso de vibriófagos encapsulados en el alimento para el control de Vibrio parahaemolitycus causante de AHPND en el camarón Penaeus vannamei

Esther Imelda Ponce García (2023, [Tesis de maestría])

"Las enfermedades causadas por bacterias del género Vibrio en el cultivo de camarón son de gran importancia debido a su impacto negativo en la industria acuícola. Estas bacterias pueden causar diversas enfermedades en camarones, como la necrosis hepatopancreática aguda (AHPND). La fagoterapia es una alternativa para el biocontrol de estas bacterias patógenas que presenta importantes ventajas, como la alta especificidad a sus huéspedes, la replicación en el sitio de infección, y la capacidad de infectar a bacterias resistentes a antibióticos. Sin embargo, la estabilidad de los fagos en el sistema de cultivo es una preocupación latente, ya que los fagos presentan una estabilidad limitada en solución y experimentan una caída significativa en el título de fagos durante el procesamiento y almacenamiento. El método de encapsulación de bacteriófagos, un área que aún no se estudia del todo, se presenta como una potencial alternativa para atender esta problemática. En el presente estudio se evaluó la eficacia terapéutica de un cóctel de bacteriófagos (vB_Vp_PvVp05, vB_Vp_PvVp07 y vB_Vp_PvVp11), encapsulados en alginato de sodio comercial y de mediana viscosidad, pectina, carboxilmetilcelulosa, liposomas y liofilizado en pectina como agente de biocontrol de Vibrio parahaemolyticus para su uso en terapias fagicas pasiva y activa. Se observó que el encapsulado en alginato de sodio de mediana viscosidad presentó la mayor liberación de fagos activos y al momento de ser incorporado a alimento para camarón y horneados a 80 – 100°C, se mantuvo una concentración de 1.3 x105 UFP/g después de 100 días de almacenamiento. Para la evaluación de las terapias pasiva y activa se realizó una infección experimental en juveniles de Penaeus vannamei para conocer la efectividad de los encapsulados, utilizando para la terapia pasiva la cepa Vp M0904 y para la activa la cepa Vp M0605. El experimento de terapia pasiva mostró una mortalidad del 80.6% en los camarones a las 48 hpi (p > 0.05) y una concentración de 5 x102 UFC/mL de Vibrio spp. no fermentativos en TCBS. En el caso de la terapia activa no se presentó mortalidades, pero hubo una disminución de la concentración de Vibrio spp. no fermentativos en TCBS con 5.56 x101 UFC/mL a las 48 hpi (p < 0.05) y aumentó la densidad de vibriófagos en 1.4 x102 UFP/mL en el agua de los acuarios (p < 0.05)..."

"Diseases caused by bacteria of the Vibrio genus in shrimp farming are of great importance due to their negative impact on the aquaculture industry. These bacteria can cause various diseases in shrimp, such as acute hepatopancreatic necrosis disease (AHPND). Phage therapy is an alternative for the biocontrol of these pathogenic bacteria, offering significant advantages, including high specificity to their hosts, replication at the infection site, and the ability to infect antibiotic-resistant bacteria. However, the stability of phages in the farming system is a persistent concern, as phages have limited stability in solution and undergo a significant drop in phage titer during processing and storage. The method of bacteriophage encapsulation, an area that is not yet fully explored, emerges as a potential alternative to address this issue. In this study, the therapeutic efficacy of a cocktail of bacteriophages (vB_Vp_PvVp05, vB_Vp_PvVp07, and vB_Vp_PvVp11), encapsulated in commercial medium-viscosity sodium alginate, pectin, carboxymethylcellulose, liposomes, and lyophilized pectin, was evaluated as a biocontrol agent against Vibrio parahaemolyticus for use in passive and active phage therapies. It was observed that encapsulation in medium-viscosity sodium alginate showed the highest release of active phages, maintaining a concentration of 1.3 x 105 PFU/g after 100 days of storage when incorporated into shrimp feed and baked at 80–100°C.For the evaluation of passive and active therapies, an experimental infection was conducted on Penaeus vannamei juveniles to assess the effectiveness of the encapsulated phages. The passive therapy experiment showed a mortality rate of 80.6% in shrimp at 48 hpi (p > 0.05) and a concentration of 5 x 102 CFU/mL of non-fermentative Vibrio spp. on TCBS agar. In the case of active therapy, no mortalities were observed, but there was a decrease in the concentration of non-fermentative Vibrio sp. on TCBS agar to 5.56 x 101 CFU/mL at 48 hpi (p < 0.05), and the density of vibriophages increased to 1.4 x 102 PFU/mL in the aquarium water (p < 0.05). It was determined that passive therapy offered no advantage for the control of Vibrio parahaemolyticus, unlike active therapy, which proved to be effective in controlling this bacterium."

Development of a thermoelectric test for electrical contactors

PABLO OROZCO CORRAL FRANCISCO JAVIER IBARRA VILLEGAS NOE VILLA VILLASEÑOR (2023, [Artículo])

In the economic model in which we develop, there is a dependence on the means of transport that every day is increasing and due to the importance of electrification in the issue of efficient and clean transportation, has caused the need for companies supplying components for automotive manufacturers to evolve and develop new technologies to stay ahead of the needs of their customers being in full evolution towards electrified transport. This evolution extends not only to manufacturing but to the test methods that currently exist, since automotive standards require suppliers to test in laboratory, the components they sell to their customers to ensure their correct operation.

THE RIGHT TO THE CITY AND URBAN-RURAL LINKAGES. COMMUNITY PARTICIPATION IN THE METROPOLITAN AREA OF TUXTLA GUTIERREZ, CHIAPAS.

Briseida Corzo Rivera Gabriel Castañeda Nolasco (2023, [Artículo, Artículo])

Access to water is a common struggle of the communities in the state of Chiapas, with the effects of urban expansion these struggles increase and with them the challenges that these populations already face, having a greater impact on the rural environment. The struggles to satisfy this basic need are a factor that has triggered processes that promote community participation. Based on a qualitative analysis, this paper compares two existing forms of participation in the rural communities of the Metropolitan Area of Tuxtla Gutierrez that allow the population to manage actions to improve their quality of life. The objective is to analyze how these processes promote or restrict the empowerment of the community and allow progress, not only in the population's access to water, but also in the construction of the right to the city. From the urban-rural linkages, the right to the city is discussed beyond the city, addressing other territories. The study identifies factors that show changes in the participation of the populations and strengthen the community, as well as factors in the relationships of the community and of the community with other actors that limit the scope of the processes.

Determinantes del comportamiento de queja del consumidor en México

Determinants of consumer complaint behavior in Mexico

IGNACIO JAVIER CRUZ RODRIGUEZ JAVIER GALAN FIGUEROA (2019, [Artículo])

El objetivo del trabajo es explicar los determinantes del comportamiento de queja del consumidor en los niveles socioeconómico y empresa. Para ello se acude a la metodología de datos de panel estático a fin de estimar el impacto de los determinantes de las quejas de los consumidores. Los resultados a nivel socioeconómico indican que las quejas se encuentran determinadas por el ingreso, las conciliaciones a favor de los consumidores y por la población residente en zonas urbanas. Mientras a nivel empresa los resultados muestran que tanto la cuota de mercado como el tamaño de la firma afectan positivamente las quejas. Se concluye que los resultados coinciden con la literatura revisada y que se puede esperar un aumento en el número de quejas presentadas por los consumidores.

This work aims to quantify the determinants of consumer complaint behavior in socioeconomic and business levels. For this purpose, the static panel data methodology is used in order to estimate the impact of consumer complaints both at the federal level of the Mexican Republic and at the level of the main companies that are considered leaders in their field. The results by the state indicate that the complaints are determined by income, reconciliations in favor of consumers and population residing in urban areas.While at the company level, the results show that both market share and company size positively affect consumer complaints. In conclusion, the results agree with the literature reviewed, and a rise in the number of complaints is possible.

Expanding the WOFOST crop model to explore options for sustainable nitrogen management: A study for winter wheat in the Netherlands

João Vasco Silva Pytrik Reidsma (2024, [Artículo])

Nitrogen (N) management is essential to ensure crop growth and to balance production, economic, and environmental objectives from farm to regional levels. This study aimed to extend the WOFOST crop model with N limited production and use the model to explore options for sustainable N management for winter wheat in the Netherlands. The extensions consisted of the simulation of crop and soil N processes, stress responses to N deficiencies, and the maximum gross CO2 assimilation rate being computed from the leaf N concentration. A new soil N module, abbreviated as SNOMIN (Soil Nitrogen for Organic and Mineral Nitrogen module) was developed. The model was calibrated and evaluated against field data. The model reproduced the measured grain dry matter in all treatments in both the calibration and evaluation data sets with a RMSE of 1.2 Mg ha−1 and the measured aboveground N uptake with a RMSE of 39 kg N ha−1. Subsequently, the model was applied in a scenario analysis exploring different pathways for sustainable N use on farmers' wheat fields in the Netherlands. Farmers' reported yield and N fertilization management practices were obtained for 141 fields in Flevoland between 2015 and 2017, representing the baseline. Actual N input and N output (amount of N in grains at harvest) were estimated for each field from these data. Water and N-limited yields and N outputs were simulated for these fields to estimate the maximum attainable yield and N output under the reported N management. The investigated scenarios included (1) closing efficiency yield gaps, (2) adjusting N input to the minimum level possible without incurring yield losses, and (3) achieving 90% of the simulated water-limited yield. Scenarios 2 and 3 were devised to allow for soil N mining (2a and 3a) and to not allow for soil N mining (2b and 3b). The results of the scenario analysis show that the largest N surplus reductions without soil N mining, relative to the baseline, can be obtained in scenario 1, with an average of 75%. Accepting negative N surpluses (while maintaining yield) would allow maximum N input reductions of 84 kg N ha−1 (39%) on average (scenario 2a). However, the adjustment in N input for these pathways, and the resulting N surplus, varied strongly across fields, with some fields requiring greater N input than used by farmers.

Contracting in teams with network technologies

Giselle Labrador Badía (2020, [Tesis de maestría])

We develop a contracting model between the owner and the workers of a firm when production depends directly on a network of synergies among workers. We aim to answer how the owner of the firm uses the network structure to maximize profits. With this purpose, we analyze two contracting regimes: single wage and perfect discrimination. We find that individual network characteristics, as well as aggregate measures, affect profits and salaries. We also study the parameters for wich the incentives to discriminate and to account for the network structure are significant.
