Resumen
Arthropod vectors are organisms capable of transmitting disease-causing pathogens to humans and animals. In Yucatán, Mexico, these constitute a public health problem that affects vulnerable sectors of the population, mainly rural communities. The main aim of this work was to promote educational strategies to infants for the prevention of vector-borne diseases (VTD) in a Yucatecan rural community. Under a qualitative-participatory approach, information was collected through community visits to conduct workshops. The infants exchanged "saberes" and knowledge about vector arthropods, VTD, prevention strategies, and vector control during educational sessions through didactic activities. Results indicate that infants identify this problem as one of the most important situations that affect their community. We concluded that it is necessary to reinforce knowledge on the subject from an early age to minimize their impact on the health of communities.

Resumen
In Mexico, the dry bean (Phaseolus vulgaris) plays a leading role as a source of low-cost vegetable protein. Among the varieties available nationally, black beans represent a large proportion of the total consumption of this legume. This paper analyzes the symmetry in the price transmission of black “bola” beans in the cases of Zacatecas (main producer) and Mexico City (main consumer center). The analysis was carried out using two time series spanning from August 2005 to September 2023. Two statistical tests indicate the presence of cointegration between prices, while the results of the threshold autoregressive (TAR) and momentum threshold autoregressive (MTAR) models suggest symmetry in the speed of adjustment between prices in a long-run equilibrium relationship. The elasticity of price transmission from Zacatecas to Mexico City was estimated at 0.8627%, ceteris paribus.

Resumen
The LGBT+ community in Peru faces significant challenges, such as social and family exclusion, low self-esteem, and stress. An environment of social acceptance and support is crucial to improve well-being and resilience to stress in this community. Through a descriptive, correlational, and cross-sectional design, we sought to identify the relationship between the variables of perceived social support, depression, loneliness, and suicidal ideation in cisgender gay men. The sample consisted of 307 subjects between 18 and 28 years old, who identified themselves as cisgender gay men. The study reveals that strong social support is related to lower suicidal ideation (r = -0.162) and depression (r = -0.146) in the cisgender gay community in Peru, as well as a negative relationship between loneliness and perceived social support (r = -0.415), thus highlighting the importance of addressing emotional burden and fostering social connections to promote well-being.

Resumen
This research is based on educational ethnography and institutional analysis. It delves about teacher’s problems during the pandemic that forced them to modify their daily lives. The objective was to reveal the repercussions and biopsychosocial challenges of teachers during confinement, as well as the adaptation to their teaching practice. This is a qualitative research with a non-experimental design. Through the biographical method, it looked for the authentic knowledge of three teachers from the state of Jalisco, Mexico, to inquire about their teaching experience during the pandemic. Results evidence that, during the pandemic, teachers made emergent adjustments to the teaching-learning processes and that they were able to solve the immediate problems related to their teaching work, although their biopsychosocial health status was complicated.

Resumen
Jaltomata (Jaltomata procumbes (Cav.) J.L. Gentry) is a Mexican native species that grows tolerated, mainly in corn fields. The present work aimed to determine harvest fruit quality and postharvest behavior of jaltomata berries harvested in October and November 2019. Also, at postharvest we observed the effect of the application of an edible coating before berries were storaged at 4 °C or 20 °C. At harvest, the November berries presented five units more of luminosity and, then, depending on storage treatment, they had 2 d or 3 d longer shelf life than that observed in October berries. Refrigeration at 4 °C increased 2 d the period of storage, without provoking chilling injury; those berries collected in November and stored at 4 °C had a shelf period of 7 d.

Resumen
The objective was to know the contribution of the floristic diversity of the low flooded (SBI) and medium semievergreen (SMS) forests, in the botanical composition of the diet of the white-tailed deer. The importance value indices (IVI) of the species, the Margalef index (Dmg), and the Shannon index (H'), as well as the botanical composition of the diet, were calculated. The greatest diversity was found in the SMS (H' = 3.96-3.99; Dmg = 12.11-12.17), in contrast to SBI (H' = 3.80; Dmg = 10.51), and 75 species consumed by deer were identified. The diet of the deer is related to a higher IVI of the species. The main species in the diet were Cladium mariscus subsp. jamaicense, Thevetia ahouai, Byrsonima bucidifolia, Machaerium cirrhiferum, and Dalbergia glabra. It is concluded that the high species diversity of tropical forests provides a high food supply to white-tailed deer, with the consumption of species from the Fabaceae, Cyperacea, Rubiaceae, and Malvaceae families predominating.

Resumen
Ultra-processed foods are products modified with the addition of substances like salt, sugar, and oil, altering their original form. This study aims to design and validate the scale of attitudes towards the consumption of ultra-processed foods in Health Sciences students. Through a quantitative, non-experimental, cross-sectional, and explanatory study, 277 students (65.7% female and 34.3% male) with a mean age of 19.16 years (DE = 1.76) were surveyed. The exploratory factor analysis revealed a one-factor structure explaining a total explained variance of 91.9%, the confirmatory factor analysis demonstrated the hypothesized one-factor model where all items had acceptable factor loadings (λ > 0.84), and the scale showed a high McDonald's omega (ω = 0.97). This study indicates that the present questionnaire is valid, reliable, and useful to measure attitudes towards the consumption of ultra-processed foods in university students majoring in Health Sciences.

Resumen
Digitalization and sustainable development are crucial for the competitiveness of Mexican micro, small, and medium enterprises (MSME) to improve processes, gain competitive advantages and strive for an economic, environmental, and social balance of economic activities. This study focused on the Mexican tourism sector and aimed to analyze the impact of digitalization and sustainable development on the performance of these companies. It is based on a sample of 555 MSME and uses eight performance indicators as dependent variables: product quality, efficiency, customer satisfaction, readiness for change, sales growth, financial profitability, employee satisfaction, and absenteeism. Results coming from a logistic regression model show a direct and significant relationship between digitalization and sustainability strategies and most performance variables. This study suggests that the corporate sector, consultants, and government can incorporate these strategies to strengthen national businesses.

Resumen
Nowadays, there is a social and work environment less resistant to change due to the incorporation of technology in the everyday life of people. This phenomena has led to changes in people’s behavior. For that reason, it is necessary that higher education institutions focus on developing students’ digital competencies that would prepare them for a workplace that demands such skills. In this research, we intend to demonstrate the importance of incorporating a social network in teaching strategies aiming to prepare digital professionals. To do this, we used Pinterest as a means to share infographics related to a subject where students can develop skills such as: research, reading, comprehension, text writing, creativity and teamwork skills. A Likert rubric was designed to be filled out by fellow students from other grades in order to obtain constructive feedback, as well as to identify areas of opportunity.

Resumen
Knowing the ecological state of the banks is an essential element in the management of a hydrographic basin, since it reflects the quality of the water and the aquatic habitat. In this study, the ecological condition of the riverbanks in eight sampling sites of the Huixtla River was evaluated through the Riverbank Ecological Quality Index (RQI) and physicochemical parameters of the water (temperature, conductivity, pH and total dissolved solids). Conditions ranged from very good to poor. The S1 site was the one with the best quality, observing a strip of continuous riparian vegetation of considerable breadth and length. The sites with poor and bad condition presented riparian vegetation in patches, retaining walls and rectified channel, compacted soil and sand extraction from the river. It is concluded that the banks need restoration measures to recover their hydrogeomorphological conditions.
