Resumen
The purpose of this study was to know the students' perception of teaching performance in a recently created educational program at a Mexican public university. This is a quantitative study through the application of a survey composed of 19 items. The sample was made up of 121 students of an educational program that began in 2020. Data processing was carried out considering the variables sex, age range and semester using descriptive and inferential statistics. The results indicate that there are no differences in the perceptions of teaching performance between men and women. Meanwhile, for most of the items there is no correlation between the age of the students and their perception of teaching performance. As for most of the items, there are no differences in the perception of teaching performance between the different semesters that students take.

Resumen
La importancia del mercado de maíz en México justifica analizar los efectos de la política agrícola en el sistema agroalimentario mexicano. El objetivo fue medir el impacto de la Política de Precios de Garantía y del Programa de Fertilizantes sobre la oferta de maíz y el sistema agroalimentario. Primero se usaron datos de precios de maíz, fertilizante, producción y elasticidades para determinar los efectos que ambos programas tendrían sobre la producción de maíz; posteriormente, se usó el simulador de impactos sectoriales de la matriz de insumo producto para determinar los efectos que se tendrían en el sistema agroalimentario. Los resultados indican que aplicar ambos programas en toda la superficie de maíz aumentaría la producción del grano en 44.2%, y que el valor de la producción en la economía se incrementaría en 48 578 millones de pesos. Los sectores más beneficiados serían aquellas industrias que utilizan al maíz como materia prima.

Resumen
This paper analyzes consumer preferences and WTP for consuming organically and locally produced fruit. Data were obtained through a face-to-face structured interview with a statistical sample of 501 consumers. An ordered probit regression model was used to estimate WTP and marginal effects. Consumers considered it important and very important that the fruit they consume is produced in Mexico (66%), without chemicals (60%), and produced by small local producers (58%). 21% and 28% of the interviewees showed WTP between 15-25% higher if the fruit is produced locally and organically respectively. Price and consumer income were the main determinants in explaining WTP (p≤0.05). The high WTP revealed by consumers could be used to design a marketing strategy for organized producers in the Sierra Nevada of Puebla

Resumen
Dengue is one of the most prevalent vector-borne viral diseases globally. The aim of this study was to identify knowledge about the mode of spread, symptoms and preventive measures against dengue and to evaluate its relationship with sociodemographic variables in two Afro-descendant communities in the Costa Chica region of Guerrero. A cross-sectional study was conducted and 36 surveys were administered. Nonparametric tests and post hoc analysis were used. A total of 8.5% of the participants had sufficient knowledge about dengue. Marital status” and ‘occupation’ showed significant differences in the level of knowledge. In particular, groups such as housewives and unemployed people showed lower levels of knowledge, which could increase their vulnerability to the disease. We emphasize the importance of designing educational interventions that consider local sociocultural characteristics to help promote preventive behaviors that reduce the incidence of dengue.

Resumen
In this work, the performance of the rotating disk photoreactor with a TiO2 semiconductor used as a photocatalyst in its crystalline form and doped with iron (Fe3+) and Silver (Ag+) metallic nanoparticles (NP) in the heterogeneous photocatalysis process for paracetamol degradation is reported. The photocatalyst was impregnated in the discs, and doping with the Fe3+ and Ag+ NPs was carried out using the photo deposition technique. The photocatalysts were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results showed that the efficiency in the degradation of toxic compounds presents a high removal of the pollutant at low concentrations.

Resumen
Suicide is one of the leading causes of death worldwide and, young people are a vulnerable group. Therefore, it is essential to identify risk and protective factors that can be worked on in clinical intervention, such as emotional regulation and clinical symptoms. The objective of this study is to generate an explanatory model of suicidal risk based on emotional regulation, and clinical symptomatology in psychology students. Method: Quantitative, non-experimental, cross-sectional study with explanatory scope, in which 295 psychology students participated. Results: the factors that explain suicide risk are depressive symptoms, emotional modification, the total score of clinical symptoms and anxious symptoms. Conclusions: the combination of emotional regulation and clinical symptomatology can play a crucial role in preventing suicide risk. This work establishes a scientific foundation to develop more effective and contextualized preventive strategies.

Resumen
Critical thinking is a fundamental skill of the 21st century and is essential in education to develop informed citizens capable of facing the challenges of today's world. In this work, the level of critical thinking of fifth-grade elementary school students in a public school in central Mexico was evaluated. A descriptive study was conducted to determine the level of critical thinking of fifth-grade elementary school students. The sample consisted of 77 students. The EdP_5P Thinking Challenges instrument was applied. Our results showed that students presented medium to high levels of critical thinking. Critical thinking did not differ in the levels of thinking of girls and boys. More research is needed that addresses other levels of development and grades of study that allow continuity of critical thinking in students throughout their school careers.

Resumen
Greenhouse production is a modern technique that allows for agricultural production under controlled conditions, optimizing both yield and product quality. The objective of this paper is to classify the municipalities of Hidalgo, Mexico, based on three variables than can determine greenhouse production, using two machine learning techniques: K-means and K-medoids. The classifications were conducted with respect to altitude above sea level, the proportion of total cultivated area with irrigation, and temperature. The results indicate that the variables considered provide useful segmentations for analyzing the suitability of the municipalities for the stablishment of new productive units. Additionally, significant relationships were found between the variables considered and the area cultivated under greenhouses in 2023.
Keywords: Protected agriculture, machine learning, Hidalgo, greenhouses.

Resumen
Well logs from the SM-1 and SM-2 groundwater wells were analyzed using spontaneous potential, natural gamma ray, resistivity, and temperature logs. The petrophysical analysis allowed the identification of porous, permeable, and less consolidated beds named here as “Arenas I, II, III, III´, IV, V”, as well as two intercalation intervals where sands alternate with more compact layers, marked as “Intercalación I and II”. The X-ray diffraction analysis in SM-2 well reports sanidine; the occurrence of this potassium feldspar interferes with using the natural gamma ray log as a shale indicator. The well log correlation between SM-1 and SM-2 is congruent. It is recommended to add more logs in future wells in order to improve the interpretation, and quantify formation parameters such as porosity and hydraulic conductivity.

Resumen
The municipality of Champotón is the main honey producer in Campeche. The purpose of this study was to identify and analyze the main socioeconomic characteristics of beekeepers, as well as the degree of association between these and hive ownership. Information was obtained through a stratified statistical sampling survey, producers were grouped into four strata: more than 50 hives, from 51 to 100, from 101 to 150 and more than 150 hives. It was discovered that beekeeping is a secondary activity, most of the producers are elderly and have extensive experience in the activity, they have basic schooling and their production capacity is based on an average ownership of 71 hives, distributed in four . apiaries. The main variable that influenced the number of hives was the status of organized producer, from which they obtain advantages in the purchase of inputs and sale of products.
