While internationalising scholarly careers is an imperative in current academia, literature has focused on the impact of such a process at the institutional, national, and international levels. Yet, internationalisation is connected to the personal dimension of careers and, consequently, it might defy academics' understanding of their working life. The intertwined between well-being and internationalisation in academia is understudied. Using data from qualitative interviews with social science scholars in Mexico, we argue that, seen from the periphery, internationalisation affects personal well-being and job satisfaction both positively and negatively. The challenges of internationalisation for work-life balance depend on the ability of academics to capitalise on their international experiences and their costs. Results indicate that there is no homogeneous positive position with respect to this imperative of academic life today. Hence, if higher education institutions are committed to pursue strategies for internationalisation, they must recognise the personal costs and benefits of this process.

Teacher productive disposition is considered as one of the key strands of mathematical proficiency. Teacher disposition and positioning (disposition in action) toward mathematics influence student learning. However, teachers' productive disposition does not always translate into productive positioning in the mathematics classroom, and vice versa. In this study, we selected teacher dis/position as the unit of analysis to explore the phenomenon of two middle school mathematics teachers' self-reported affective disposition and observed positioning-by-others. Grounded in positioning theory the relationship between teacher disposition and positioning-by-others was examined utilizing a cross-case analysis. Results of the study indicate that dispositional characteristics such as attitude, self-concept, and nature of mathematics were significantly different between the cases. The study findings also suggest that interconnectedness between teacher core disposition and positional situatedness could potentially contribute to understanding and addressing the complexity of teaching and learning in the mathematics classroom.

Learning basic programming concepts in computer science-related fields poses a challenge for students, to the extent that it becomes an academic-social problem, resulting in high failure and dropout rates. Proposed solutions to the problem can be found in the literature, such as the development of new programming languages and environments, the inclusion of virtual and augmented reality, gamification, automatic grading tools, and intelligent tutoring systems, among others. However, most of these solutions do not explicitly describe the application of some learning theory, instead, they focus on new technologies. Cognitive Load Theory (CLT) is an instructional design theory that aligns the design of instructional materials with human cognitive architecture using 17 design guidelines to optimize learning. The goal of this research is to design, develop, and test instructional materials to support the teaching and learning of basic programming, measuring their effectiveness compared to traditional materials, based on the self explanation effect of CLT. To compare the instructional materials, a quasi-experimental design with homogeneous groups was used, involving students from the Autonomous University of Aguascalientes. The results indicate a positive impact of the use of CLT-based instructional materials, either through the application of a single effect or the combination of two effects such as worked example and self-explanation.

This article reports on effects of two earthquakes in Mexico on adolescents attending middle school. The earthquakes struck in close succession during the implementation of a school-based prevention program, providing an opportunity to assess emotional distress due to the earthquakes and whether the life skills taught in the program affected how students coped with the natural disaster. The objectives were to (1) evaluate the earthquakes' impact on students' distress; (2) assess if distress is associated with internalizing symptomology and externalizing behaviors; and (3) investigate if students receiving the original and adapted versions of the intervention coped better with the events. A Mexico-US research team culturally adapted "keepin' it REAL" to address connections between substance use among early adolescents in Mexico and exposure to violence. A random sample of public middle schools from three cities (Mexico City, Guadalajara, and Monterrey), stratified by whether they held morning or afternoon sessions, was selected. A total of 5522 7th grade students from 36 schools participated in the study. Students answered pretest and posttest questionnaires; the latter assessed earthquake-related distress and coping strategies. Earthquake-related distress was associated with all measures of undesired internalizing symptomology and externalizing behaviors. Compared to controls, students in the adapted intervention reported less aggressive and rule-breaking externalizing behavior and less violence perpetration. However, these intervention effects were not moderated by the level of earthquake-related distress, and they were not mediated by positive or negative coping. The findings have implications for prevention intervention research and policy as natural and human-made disasters occur more often.

Adopting learner-centred teaching approaches is important to advance student performance in Mexican rural communities, which have historically been disadvantaged. Yet, little research exists on the factors that might promote the use of this teaching approach. In the study reported on here we examined the associations between principals' transformational leadership, school climate, teacher commitment to learners, and learner-centred teaching practices. In total, 174 teachers were selected from 26 tele-secondaries in the state of Tabasco, Mexico. A structural equation model was calculated. Results do not provide evidence to support a direct association between transformational leadership and the use of learner-centred teaching. However, an indirect relationship was found between the effects of school climate and teacher commitment. These findings indicate that enhancing school climate and teachers' commitment through a transformational leadership style are key to foster an environment for learner-centred teaching.

Professional growth of STEM teacher educators remains an underdeveloped topic in educational research. In the current study, STEM teacher educators representing six countries: Argentina, Brazil, Chile, Colombia, Mexico, and USA completed a survey, which addressed teacher educators' professional trajectories, practices, and challenges they face to meet tenure requirements. This study utilized convergent mixed methods design applying survey research format and as such integrated both quantitative and qualitative data collection and analysis. Descriptive statistics and meaning coding of the survey and interviews allowed identification of emerging themes in professional practices. The main findings suggest that there are common trends as well as country specific professional practices across professional trajectories reported by participants. The study results reveal that the lack of support during the teacher-to-teacher educator transition period was a common feature across the countries. It was also evident among participants that their professional journey begins with an assumption that as teacher educators they should primarily excel in performing teaching tasks.

A binational team of investigators culturally adapted, implemented, and tested the efficacy in Mexico of "keepin' it REAL," a US-designed prevention intervention for youth. This article reports on the social validity of the adapted intervention by assessing its feasibility, acceptability, and utility, as perceived by participating middle school students, teachers/implementers, and school administrators. Middle schools (N = 36) were randomly assigned to (1) the culturally adapted version for Mexico ("Mantente REAL"), (2) the original intervention from the USA ("keepin' it REAL") translated into Spanish, or (3) a control condition (treatment as usual). Adult and child feedback about the adapted and original versions of the intervention indicate that both are feasible to implement in the Mexican context. Implementation fidelity was equally high for both versions of the manualized intervention. Students, however, were more satisfied with the culturally adapted version than with the non-adapted version. They reported gaining more knowledge, finding it more acceptable, applicable, and authentic, and they reported discussing the program with their family and friends more often. The findings support the feasibility of engaging classroom teachers to implement manualized prevention programs in Mexico. These findings also advance prevention science by documenting the importance of cultural adaptation as a means to increase students' identification with and acceptability of efficacious school-based interventions. The article discusses the practice, policy, and future prevention research implications of the findings for Mexico and their potential generalizability to other middle- and lower-income countries.

The consolidation of smartphones as dominant devices for access to digital information and entertainment has redefined the processes of production and commercialization of cultural communication industries. The nature of these screens, which prioritize the visual content over the sound, decisively influences distribution strategies in the audio market: radio operators, streaming music platforms and podcast creators need to adapt their value chains to the habits derived from this mediation, especially in the younger audience. This research identifies the practices of mobile use as an audio receiver among adolescents in Colombia, Spain and Mexico--the most representative countries of Spanish-speaking digital sound consumption--based on a descriptive study on a thousand subjects from 13 to 19 years of age. The results confirm the overwhelming dominance in this music menu in the face of low penetration of radio and podcast word content. The selection is based on personal criteria, with little margin for the prescription of family or friends. There is evidence of the roots of individual listening, linked to the brand and the visibility of audio providers, who are obliged to develop diffusion logics based not only on thematic or genre preferences, but also on the user experience.

The tutorship program is aimed at supporting students throughout their university career and its objective is to prevent future problems of adaptation in the educational ambience as well as intervening in matters of academic achievement. At the Instituto Tecnológico de Sonora (Technological Institute of Sonora) (ITSON), the individual tutorship program began in 2000. In 2002 group tutoring began in order to see to the entire first year student population and today, group tutoring is offered in both the face-to-face and virtual modalities. The general objective of the present study is to determine the impact the programs of face-to-face and virtual tutoring at the ITSON has had on students' academic achievement, during the four semesters after having participated in this program. Information on 2,995 students from the different areas of study offered at the university was collected from databases which existed at the Institute and analyzed using different statistical techniques. The tutoring program is shown to have had a favorable impact on the index of students' failing classes, during the semester they were enrolled in tutoring, but not during the subsequent semesters, during which they did not participate in the tutorship program. The grade point averages obtained by students who had face-to-face tutoring were statistically different from those of the students who did not have tutoring. This was true for all of the semesters analyzed. The same thing happened with the students who had virtual tutoring except for during the second semester when the two were statistically equal.

Purpose: The purpose of this study was to use Watkins and Marsick model of a learning organization (1993, 1996), the dimensions of the learning organization questionnaire as a framework for interdisciplinary network collaboration and knowledge sharing. Design/methodology/approach: The research team used a mixed-methods approach for data collection. Survey data was collected from 181 networks. In addition, data was collected from two focus groups with six participants each. Findings: Results, in general, showed that the learning organization culture could be used as a framework for interdisciplinary network collaboration. In particular, results showed that shared vision, imbedded systems and knowledge sharing were key driving forces required for successful collaboration. Research limitations/implications: Theoretical and practical implications were discussed, and conditions for learning organization culture for networks were established. Originality/value: People in a network era need more than training; they need ongoing, interdisciplinary, collaborative support to solve complex problems. Organizations can only work effectively if barriers to organizational learning were removed. This originality of this paper lies in applying learning organization framework at the network level.

We focus on the binational educational lives of Otros DREAMers students to address Keith Gilyard's insistence that if translingualism is to become an attractive alternative to scholars invested in combating pernicious language instruction, it must promote analyses that don't overlook or devalue the struggles of traditionally underrepresented groups.

Latent autoimmune diabetes in adults (LADA) is characterized by the presence of glutamate decarboxylase autoantibodies (GADA). LADA has intermediate features between type 1 diabetes and type 2 diabetes. In addition, genetic risk factors for both types of diabetes are present in LADA. Nonetheless, evidence about the genetics of LADA in non-European populations is scarce. This study aims to perform a genome-wide association study with a phenome-wide association study of LADA in a southeastern Mexican population. We included 59 patients diagnosed with LADA from a previous study and 3121 individuals without diabetes from the MxGDAR/ENCODAT database. We utilized the GENESIS package in R to perform the genome-wide association study (GWAS) of LADA and PLINK for the phenome-wide association study (PheWAS) of LADA features. Nine polymorphisms reach the nominal association level (1 × 10−5) in the GWAS. The PheWAS showed that rs7305229 is genome-wide and associated with serum GADA levels in our sample (p = 1.84 × 10−8). rs7305229 is located downstream of the FAIM2 gene; previous reports associate FAIM2 variants with childhood obesity, body mass index, body adiposity measures, lymphocyte CD8+ activity, and anti-thyroid peroxidase antibodies. Our findings reveal that rs7305229 affects the GADA levels in patients with LADA from southeastern Mexico. More studies are needed to determine if this risk genotype exists in other populations with LADA. [ABSTRACT FROM AUTHOR]

Background: There is a significant gap between the prevalence of child and adolescent mental illness in Mexico and access to mental health services, especially those that are evidence-based. School-based interventions can significantly narrow this gap. Objective: The study evaluated the effectiveness of the interventions "Dejando Huellitas en tu Vida" (Leaving Traces on Your Life [Huellitas]) and "Criando con Amor, Promoviendo Armonía y Superación en México" (Raising Children with Love, Promoting Harmony and Self-Improvement [CAPAS-Mx]). Methods: Participants were 215 caregivers (M[subscript age] = 38.4 years, SD = 8.9, 82.9% women) and 202 children (M[subscript age] = 8.6 years, SD = 1.3, 44.06% girls) from four public schools randomly assigned to four experimental conditions (Huellitas, CAPAS-Mx, Huellitas-CAPAS-Mx, and Control) with pre-test and post-test assessments. Results: Caregivers in the multicomponent condition reported significantly lower scores in child externalizing problems and higher scores in discipline, skills encouragement, social adaptation, emotional control and prosocial behavior than caregivers in the control group. There were also improvements in parents' use of effective discipline and skills encouragement in the CAPAS-Mx group over the control group. Among the children, only those in the Huellitas condition showed a decrease in mediation. Conclusions: Findings support the implementation of the multicomponent intervention in public school settings.

This study reports on the impact of international visiting faculty's teaching experiences in the United States on their personal, professional, and intercultural development. It is based on the principles of qualitative research and can be described as a case study. Data collection involved a questionnaire, a written narrative, and a semi-structured interview with each of a number of teachers. Participants included a group of 22 visiting faculty. Three main categories, each of which can be subdivided into benefits and challenges, emerged from the analysis: intercultural matters, professional matters, and personal matters. A wide range of benefits was identified, suggesting that the participants adapted to new life styles, became more mature, obtained a deeper understanding of themselves, reaffirmed their own educational values and philosophies, raised cultural awareness, became more flexible, and developed attitudes that involved tolerance and respect. Conversely, visiting faculty reported that they faced challenges related to language barriers, interaction with native speakers, classroom management, lack of support from school administrators, and separation from family.

Reading is one of the aspects that help students achieve optimal performance in their education. There are several determining factors that can affect reading, particularly its promotion by teachers, and the students' behavior and comprehension. This paper seeks to determine the relationship between reading promotion, behavior, and comprehension and educational achievement in Mexican high school students. Our sample consisted of 7,299 students, with an average age of 15.8 years. We analyzed their answers to a questionnaire as well as the database from the 2018 Program for International Student Assessment (PISA) test. A theoretical model was built using the reading promotion, reading behavior, reading comprehension, and educational achievement factors; the model was evaluated using the structural equation modelling technique. We found a positive and significant relationship between reading promotion, behavior, and comprehension and educational achievement. We conclude that, in order to improve educational achievement, teachers should perform specific actions to promote favorable reading behavior and comprehension among high school students in Mexico.

Measures of teaching are used internationally to understand and improve quality in early education with little consideration for ecological validity. In this study, we analyze videos gathered in 58 K-1 classrooms in Central Mexico to evaluate the validity and reliability of scores from an observational tool developed in the U.S. and used internationally: the Classroom Assessment Scoring System (CLASS). We use mixed methods to examine ecological validity to propose a revised, better-fitting three-factor solution of the CLASS in Mexico: Emotional Support (Positive Climate, Negative Climate), Social Relationships for Teaching (Teacher Sensitivity, Instructional Learning Formats, Behavior Management, Productivity), and Instructional Interactions (Regard for Student Perspectives, Concept Development, Quality of Feedback, Language Modeling). Generalizability study findings demonstrate moderate reliability across three sources of measurement error: raters, days, and video segments. These findings support the need for a 'unified approach to validity' to develop, adapt, and refine measures of teaching as a basis for enhancing teacher development and teaching quality in early education in Mexico and throughout Latin America.

The low fertility levels observed in Mexico in recent years have been accompanied by high levels of poverty. The paper analyzes the effect of multidimensional poverty on the observed levels of fertility at the municipal level, that is, the relationship between the spatial dispersion of fertility and the observed levels of poverty. The analysis is based on the application of two hierarchical Bayesian models, the first one representing a spatial field that adjusts the behaviour of the total fertility rate and a second one that adds the effect of the poverty covariate to the spatial field. The results show that an increase in municipal poverty levels would cause a significant increase in fertility rates, which is evidenced by the formation of spatial clusters where high levels of fertility and poverty are observed.

A reduction in platelet count in critically ill patients is a marker of severity of the clinical condition. However, whether this association holds true in acute kidney injury (AKI) is unknown. We analyzed the association between platelet reduction in patients with AKI and major adverse kidney events (MAKE). In this retrospective cohort, we included AKI patients at the Hospital Civil of Guadalajara, in Jalisco, Mexico. Patients were divided according to whether their platelet count fell >21% during the first 10 days. Our objectives were to analyze the associations between a platelet reduction >21% and MAKE at 10 days (MAKE10) or at 30-90 days (MAKE30-90) and death. From 2017 to 2023, 400 AKI patients were included, 134 of whom had a > 21% reduction in platelet count. The mean age was 54 years, 60% were male, and 44% had sepsis. The mean baseline platelet count was 194 x 103 cells/µL, and 65% of the KDIGO3 patients met these criteria. Those who underwent hemodialysis (HD) had lower platelet counts. After multiple adjustments, a platelet reduction >21% was associated with MAKE10 (OR 4.2, CI 2.1-8.5) but not with MAKE30-90. The mortality risk increased 3-fold (OR 2.9, CI 1.1-7.7, p = 0.02) with a greater decrease in the platelets (<90 x 103 cells/µL). As the platelets decreased, the incidence of MAKE was more likely to increase. These associations lost significance when accounting for starting HD. In our retrospective cohort of patients with AKI, a > 21% reduction in platelet count was associated with MAKE. Our results are useful for generating hypotheses and motivating us to continue studying this association with a more robust design. A reduction in platelet count in critically ill patients has been associated with a worse prognosis, but it is not yet known whether this relationship also exists in patients with acute kidney injury, who are more susceptible to platelet decrease due to the syndrome or due to the onset of hemodialysis. In our study of acute kidney injury patients, we found that those whose platelet count decreased >21% during the first days were more likely to experience a major kidney event. In addition, the greater the decrease in platelet count was, the more likely these events were to occur. The significance of this association was lost in patients who start hemodialysis. Our conclusions could serve to generate hypotheses about this interesting relationship. [ABSTRACT FROM AUTHOR]

This study analyzed the narratives of a group of college students in so-called "Citizen Experience Reports" (REC). These reports provide an account of experiences carried out by students during their social service. The objective was to analyze these narratives and identify the level of development of related skills concerning citizenship, using for this purpose the institutional definition of citizenship and the operative model created by Cantu, García and Ochman (2008). It was found that some of the components of the competences related to the citizen construction such as tolerance, respect, analysis, judgment, responsibility, and identity are the most common references in the student's narratives and that some variables such as gender may establish differences in these reports.

Purpose: The purpose of this paper is to analyze the relationship among undergraduate students' perception of faculty members' and institutional support, undergraduate students' appreciation of scientific skills and undergraduate students' research endeavors. Design/methodology/approach: A structural model was calculated to relate the variables. The sample included 1,882 undergraduate students from a State University located in the Southeast of Mexico. Undergraduate students came from different fields, and all of them that had taken at least 60 percent of their curricular credits. Findings: The structural model suggests that faculty members' and institutional support are positively related to undergraduate students' appreciation of scientific skills and undergraduate students' research endeavors. The findings suggest faculty members' and institutional support are key factors to develop scientific research in undergraduate students. Therefore, the researchers argue that science programs taught in Mexican colleges and universities must endorse supportive practices among faculty members and institutions. Research limitations/implications: The cross-sectional design does not allow to set clear causal relationships among the explored variables. In addition, the sample included only one public university. Thus, further empirical research with research participants from different universities across the country is suggested. These improvements may enhance the strength of the proposed theoretical model. Practical implications: Currently, there are a plethora of studies looking at students' attitudes toward science. Those studies have also discussed the conditions and contexts that influence research practice among undergraduate students. Nonetheless, there are no studies known by the authors that include the set of variables and relationships considered in the present study. Originality/value: Despite the plethora of studies looking at several conditions and contexts influencing undergraduate students' attitudes toward science, no studies known by the authors have included the set of variables and relationships considered in the present study.

Objective. To examine the correlates of non-compliance with the movement behaviors (MB) recommendations, and the association with nutritional status in Mexican schoolchildren and adolescents. Materials and methods. Cross-sectional study with data from the National Health and Nutrition Survey 2022-2023 (Ensanut 2022-2023), including MB (physical activity, sedentary behavior and sleep), sociodemographic characteristics (sex, well-being index, educational level, and rural/urban area) and nutritional status (body mass index). Univariate and multivariate logistic regressions were used. Results. Being female, living in urban areas, and having a higher well-being index were associated with not meeting any of the three MB recommendations (schoolchildren) or some individual MBs (schoolchildren and adolescents). Not meeting any of the three MB recommendations was associated with higher odds of being overweight or obesity in adolescents. Conclusions. Strategies to promote healthy MB with a gender perspective, especially in urban areas and among those with a higher well-being index, should be prioritized. [ABSTRACT FROM AUTHOR]

The use of medicinal plants among local experts and the general population of San Sebastián Coatlán, Oaxaca, Mexico was documented. A total of 117 medicinal species were recorded, 61% of which are native to Mexico, being used to treat 16 types of illnesses. In total, 44.4% of medicinal species can be obtained from home gardens. Local experts and general population contribute similarly to the total knowledge of medicinal plants. In total, 45% of the medicinal plants are herbaceous, and 65% are cultivated. Community traditional knowledge about medicinal plants is distributed and conserved among all members of the locality. [ABSTRACT FROM AUTHOR]

The microeconomic research about private expenditures on educational goods and services shows that the variation in investment levels reflects differences in income, socio-demographic characteristics, and the average number of household members. There are few studies in Latin America, however, that also explore the income elasticity of educational demand. This article addresses this important gap in Mexico, using data from the 2020 National Survey of Household Income and Expenditures. By means of Engel curves and tobit regression analysis, this article outlines the values assigned to education according to family traits. In particular, the results show that, as we focus on economically wealthier households, education is no longer a superior good, without becoming a necessity good. In addition, the data show evidence of gender differences that are opposite to those pointed out in the peer-reviewed literature. [ABSTRACT FROM AUTHOR]

Objective: The objective of this study was to associate the epidemiological and clinical characteristics of patients hospitalized for COVID‐19 with the progression to critical illness and death in northwestern Mexico. Methods: From March to October 2020, we collected the demographic and clinical characteristics of 464 hospitalized patients from northwestern Mexico. Results: Sixty‐four percent (295/464) of the patients became critically ill. Age, occupation, steroid and antibiotic use at previous hospitalization, and underlying diseases (hypertension, obesity, and chronic kidney disease) were associated with critical illness or death (p: < 0.05). No symptoms were associated with critical illness. However, the parameters such as the heart rate, respiratory rate, oxygen saturation, and diastolic pressure and the laboratory parameters such as the glucose, creatinine, white line cells, hemoglobin, D‐dimer, and C‐reactive protein, among others, were associated with critical illness (p: < 0.05). Finally, advanced age, previous hospital treatment, and the presence of one or more underlying diseases were associated with critical illness and death (p: < 0.02). Conclusions: Several epidemiological (e.g., age and occupation) and clinical factors (e.g., previous treatment, underlying diseases, and vital signs and laboratory parameters) were associated with critical illness and death in patients hospitalized with COVID‐19. These data provide us with possible markers to avoid critical illness or death from COVID‐19 in our region. [ABSTRACT FROM AUTHOR]

The main objective of this study was to analyze the relationship between Geriatric Syndromes (GSs) and in-hospital mortality in adults aged 65 and older admitted to the Emergency Department (ED). The study included 202 Older Adults (OAs) who met the inclusion criteria. We conducted a Comprehensive Geriatric Assessment and collected clinical and demographic data. A univariate analysis was carried out for each of the GSs analyzed. Those variables with p < 0.05 were entered into a multiple logistic regression using the backward stepwise entry method to analyze the independent predictor variables. The average number of GSs per individual was 4.65 (±2.76). Frailty syndrome was the most prevalent (70.2% of patients). Our study found an association between mortality and some GSs, such as frailty (p = 0.042), risk of falls (p = 0.010), delirium, cognitive impairment, dependence, and risk of ulcers (p < 0.001). We found that cognitive impairment (adjusted OR, 6.88; 95% CI, 1.41–33.5; p = 0.017) and dependence (adjusted OR, 7.52; 95% CI, 1.95–29.98; p = 0.003) were independent predictors associated with mortality in our population. It is necessary to develop new care strategies in the ED that respond to the needs of aging societies, including the use of new technologies and personnel with experience in gerontology.

In this case study, we propose a network analysis approach to map social movements through an intersectional feminist lens. We aim to gain a more in-depth understanding of movements' network structures to examine the roles and relationships of movement actors, the flow of resources between them, and potential areas of collaboration and conflict. By incorporating Social Network Analysis (SNA) techniques and visually mapping dynamics within social movements, this approach can assess the significance of small actors in creating change and stresses the need for their perspectives to be heard. Furthermore, our methodology adopts a feminist intersectional framework that recognizes the role of different identities in shaping the movement and its actors. To demonstrate the practical application of this approach, we examined the movement for the right to abortion in Mexico between September and December 2021. Our multi-step process included (1) designing a survey tool adapted to the context of the movement, (2) collecting and analyzing survey responses on movement actors' relationships and interactions, including their priorities, activities, needs, risks, and challenges, (3) visualizing the network using SNA techniques that account for the complexity and diversity of the movement, (4) interpreting the findings through insights collected in semi-structured interviews and validation meetings with key movement actors, and (5) implementing safety and security guidelines to safeguard the identity of individuals whose activities could put them at risk of suffering institutional, emotional, and physical violence. Our case study offers valuable insights that not only encourage the integration of feminist and intersectional perspectives into data collection processes but also provide a roadmap for accompanying social movements and supporting meaningful and contextually responsive activities.

Agroforestry practices that include trees on grazing lands could enhance atmospheric CO2 sequestration and storage. However, carbon sequestration rates and storage capacity of intensively grazed agroforestry systems vary due to the diversity in species composition, stand structure, system age, and management practices. The objective of this study was to evaluate carbon stocks and accrual rates in Leucaena leucocephala + Cynadon plectostachyus, and Brachiaria decumbens grass silvopastoral systems and compare them with conventional open grazing lands. The study was carried out in Chiapas in southern Mexico, one of the hotspots of deforestation driven by the expansion of livestock farming. We measured above- and belowground carbon stocks in 18 silvopasture (SP) plots, with the plantation age ranging from 2 to 10 years. Nine plots of adjacent conventional full-sun grasslands (open pasturelands) grazed rotationally were sampled for comparison. The average tree biomass stock in SP was 5.5 ± 1.9 Mg C ha−1 and differed with SP age. Mean annual biomass accrual rates ranged from 0.25 to 2.57 Mg C ha−1 year−1, indicating that SP systems are CO2 sinks, excluding other sources of GHG such as methane emissions from enteric fermentation. The average soil organic carbon (SOC) sequestration rate of SP was 0.143 ± 0.043 Mg C ha−1 year−1 to 50 cm depth. The SOC sequestration rates correlated positively with SP age at the beginning and decreased after about 8 years. The results suggested that the age and lifespan of trees play a significant role in aboveground C sequestration through the Leucaena leucocephala SP, while SOC storage varied with soil properties. Further research on the relative response of active and stable SOC fractions along with soil CO2 fluxes could explain the results on the SOC storage potential of these agroforestry systems.

COVID-19 is no longer a public health emergency of international concern, but long COVID's effects are yet to be fully understood. Hence, globally, SARS-CoV-2 is still a profound threat to public health and of perilous nature as a zoonotic disease. Timely vaccination provided to individuals worldwide during the pandemic phase was under a certain degree of control; however, few studies have reported the effectiveness of vaccines administered in Mexico, and its surveillance is paramount. Furthermore, an unknown proportion of Mexican individuals have not yet received any vaccine, and the circulation of the Omicron, Pirola, and FLiRT variants is ongoing. A cross-sectional serology survey study design was employed, involving 150 individuals from Southern Mexico (Oaxaca) whose humoral immune responses after vaccination were tested by an ELISA; the receptor-binding domain of the SARS-CoV-2 spike protein served as a recombinant antigen in the ELISA. One hundred thirty-nine out of 150 individuals (92.6%; 95%-CI = 87–95%) examined were positive for the ELISA, but in 11 individuals, the vaccines did not induce any immune response. Interestingly, the immune responses (antibody prevalence and levels) of females (58%) were higher (T= −2.21; p-value = 0.02) than those of males (41%). However, in this sample population of Southern Mexico, age, vaccine type, comorbidity, and body mass index did not have any effect (p > 0.05) after COVID-19 vaccination. Taking all results together, here, we present factors that affected immune responses of individuals during the first vaccination campaign in Oaxaca, Mexico; however, vaccine surveillance during the post-pandemic phase needs further investigation.

Purpose –The purpose of this paper is to contribute to the understanding of the relationship between different types of organizational culture (hierarchical, clan or group, market or rational and adhocratic) and sustainability through three dimensions (economic, environmental and social) in ecotourism businesses in Oaxaca and Chiapas, Mexico. Design/methodology/approach – In this research 80 questionnaires were administered in the form of faceto-face interviews to ecotourism business owners’. Through a discriminant analysis and the theoretical support of the competing values framework (CVF), the prevailing types of culture were identified, and their influence was analysed through a regression analysis. Findings – The results show that ecotourism businesses which are driven by hierarchical culture tend to have a greater focus on economic sustainability, while those businesses with a market or rational culture show a positive and significant influence on environmental sustainability. Likewise, businesses with adhocratic culture achieve sustainability holistically; however, the data reveal that clan or group culture is not associated with social sustainability. Originality/value – This study offers empirical research that explains the relationship between organizational culture and sustainability. Additionally, it contributes to the study of environmental management issues in the ecotourism sector. [ABSTRACT FROM AUTHOR]

The purpose of this study was to survey and report on the empirical literature at the intersection of science education research in Latin American and previous studies addressing international research trends in this field. Reports on international trends in science education research indicate that authors from English-speaking countries are major contributors of publications. Despite the internationalization of the science education community, as represented by the publication of the work generated in non-English-speaking countries, research trends in science education in Latin America are uncommon in the literature. Therefore, it was deemed important to explore the scholarly productivity of science education researchers from Latin America to learn about the research orientations pursued by scholars from this region. Collective review findings are presented with respect to author's nationality, publication volume generated in each country, research type and topic, collaborative research, and areas for future research. Of the ten countries represented in this study, Brazilian authors were the most research active scholars followed by their colleagues from Venezuela, Mexico, and Argentina. The History, Philosophy and the Nature of Science (HPNOS) was the topic that most attracted the interest of Latin American science education researchers, and the Empirical Qualitative studies was the most frequent research type combination in the analyzed publications. Findings in this study suggest a relationship between investment power in Research and Development (R&D) and the scholarly productivity not only in science education but also in the scientific field in the countries of the region.

This article examines the nature and evolution of the term blended learning (BL), which encompasses numerous connotations, including its conception as a strategy, delivery mode, opportunity, educational shift, or pedagogical approach. Although much has been said in this field, very few studies examine the different types of blends behind their implementation. To address this gap in the literature, the article indicates types of blends and analyses the characteristics of BL, its benefits and limitations, supported by a review of literature, and an analysis of a sample of BL cases in higher education language-teaching worldwide. Additional data were also gathered through a questionnaire administered to language department chairs. Data were triangulated and analysed using the grounded theory approach. The article closes with an examination of different levels of blending, the various perspectives within the educational community on its use, and a discussion of its future applicability, especially in higher education.

Background: The SARS-CoV-2 pandemic brought a radical shift in the healthcare system and suboptimal care for vulnerable patients, such as those with Type 2 Diabetes Mellitus (T2D). Therefore, we compared metabolic control and macro/microvascular complications of patients with T2D before and throughout the three-year SARS-CoV-2 pandemic. Research design and methods: A retrospective observational cohort of subjects with T2D studied from 2018 to 2022 in Northern Mexico was treated by a dynamic multidisciplinary team. Levels of Glycated hemoglobin (HbA1c), fasting serum glucose (FG), LDL-Cholesterol (LDL-C), blood pressure (BP), albuminuria, triglycerides, Body Mass Index (BMI), and FIB-4 score, micro and macrovascular complications were evaluated. Results: A total of 999 patients were studied, 51.7% males with a mean (SD) age of 60.1 (12.7) years. Adequate glycemic control based on HbA1c increased by 15.2% and 42.3% in FSG (p < 0.001) between the beginning 2018 and the end of 2022. LDL-C control decreased by 5.1% between 2018 and 2022 (p < 0.001). Systolic BP control decreased by 2.6% (p < 0.001), whereas diastolic BP control increased by 1.8% (p = 0.01) between 2018 and 2022. Albuminuria control increased by 8.5% (p = 0.002). When comparing the Area Under the Curve (AUC) of metabolic parameters between patients who developed SARS-CoV-2 vs. those who did not, AUC was statistically higher in those who developed SARS-CoV-2 (p < 0.05). Diabetic neuropathy was the most prevalent microvascular complication (n = 35; 3.6%); ischemic heart disease was the most frequent macrovascular complication (n = 11;1.1%). Conclusions: A multidisciplinary dynamic team that adapts to the pandemic SARS-CoV-2 maintains and increases metabolic control in subjects with type 2 diabetes in Mexico. This represents a low percentage of chronic complications. The AUC of metabolic parameters of subjects with SARS-CoV-2 infection is higher, reflecting more variability in metabolic control.

Simple Summary: The Worthen sparrow (WS) is an endemic species of the Mexican rangelands that is considered endangered. The objective of this study was to document the building materials for nest building of this obligate grassland bird species. After completing the breeding season from 2013–2016, 207 empty nests were collected to analyze the construction materials used in their assembly. The findings revealed that Muhlembergia torrey was a key component of the WS's nest. The study was conducted within a well-managed beef cattle operation in northeastern Mexico. Each nest was weighed and dissected to obtain the plant and animal material used to build the nests. The number of materials present per nest and relative frequency were determined. Twenty-one building materials were used. Over the years, Muhlenbergia torreyi represented 85.5% of the total biomass of the nests, and Aristida longiseta, Bouteloua gracilis, Brickellia canescens, Purshia mexicana and Cirsium ehrenbergii constituted 2.45, 2.80, 2.44, 1.34 and 1.11% of the total biomass, respectively. The above-mentioned grasses represented 95.62% of the total biomass. Material of animal origin was horse and cow hair, which represented 0.84 and 0.58% of the total biomass, respectively. It was concluded that, at the study site, Muhlenbergia torreyi was a key nest-building material for the Worthen sparrow nest. [ABSTRACT FROM AUTHOR]

Louis-Eugène-Gabriel de Ferry de Bellemare, better known as Gabriel Ferry, was a Frenchman with a successful literary career. A native of Grenoble, he went to Mexico in the 1830s as part of a French migratory flow that settled in the ports and cities of the interior, in search of a better future (Ferry was interested in commercial opportunities). Although Ferry is known as a traveler, he was also a migrant, traveling throughout Mexico for 7 years. He recorded his impressions, which were influenced by Romanticism, in novels and travelogues. This article examines Ferry's impressions of northwestern Mexico, particularly his commentaries about landscapes, economy, and society, documented in his Mexican-themed writings, Scènes de la vie sauvage au Mexique, Le coureur des bois ou les chercheurs d'or, and Impressions de voyages et aventures dans le Mexique, la Haute Californie et les régions de l'or.

We analyzed the geographical distribution of Habromys species based on distributional data from museum specimens, web databases, and literature. We recorded species-presence data of each species in 0.5° × 0.5° grid cells and biogeographic provinces in Mexico and Central America. We analyzed the association between vegetation types and land use. We carried out species distribution models of most species of Habromys and those tree species frequently harboring these mice, finding a high distributional congruence among mice and trees. Species of Habromys occur throughout the montane systems of Mexico and northern Central America, so they can be considered characteristic elements of the Neotropical montane cloud forests. All species of the genus occur in Mexico, whereas Guatemala and El Salvador have only one species. Although all species of Habromys are highly restricted and considered rare species, only one (H. simulatus) is currently protected by Mexican laws. We assigned two species to a high and four to the critical conservation risk. Habromys species contribute to the recognition of Mesoamerica as a biodiversity hotspot. [ABSTRACT FROM AUTHOR]

The changing supply and demand of hydrocarbons in recent years, generated by inflation, pandemics, and wars, have impacted its price considerably, developing limitations in maintenance processes in the oil industry worldwide; however, the mechanical deterioration of facilities due to corrosion does not stop. This article contributes original to the knowledge and management of a pipeline transportation system (PTS) without an immediate high impact that would help reduce property loss due to corrosion through the development of intelligent evaluation models that combine field data, laboratory, and cognitive knowledge in a case study in Mexico. The research is divided into Part 1 (Modeling; https://doi.org/10.1515/corrrev-2021-0080) and Part 2 (Operational and economic risk analysis of PTS under corrosive effects, using Monte Carlo simulation, MCS), supported by information and knowledge of 564 km of soils, from cathodic protection studies, essential to determine corrosive profiles of the PTS, considering supply and demand effects, with 1095 data on the price of the Mexican mixture from 2016 to 2019, as well as data monthly inflation rates for the same period, to generate financial estimates representative of the system, in search of replicable exchange actions and practices in international fields.

TwinsMX registry is a national research initiative in Mexico that aims to understand the complex interplay between genetics and environment in shaping physical and mental health traits among the country's population. With a multidisciplinary approach, TwinsMX aims to advance our knowledge of the genetic and environmental mechanisms underlying ethnic variations in complex traits and diseases, including behavioral, psychometric, anthropometric, metabolic, cardiovascular and mental disorders. With information gathered from over 2800 twins, this article updates the prevalence of several complex traits; and describes the advances and novel ideas we have implemented such as magnetic resonance imaging. The future expansion of the TwinsMX registry will enhance our comprehension of the intricate interplay between genetics and environment in shaping health and disease in the Mexican population. Overall, this report describes the progress in the building of a solid database that will allow the study of complex traits in the Mexican population, valuable not only for our consortium, but also for the worldwide scientific community, by providing new insights of understudied genetically admixed populations.

This article demonstrates how digital information and communication technologies (ICTs) (Zoom/WhatsApp) unexpectedly and counterintuitively proved to be valuable tools for community-engaged health research when, in the context of the COVID-19 pandemic, they were integrated into a research study testing a peer support group intervention with female immigrants from Mexico. Because of pandemic restrictions, we changed the study protocol to hold meetings remotely via Zoom rather than in person as originally planned. Because we recognized that this would lack some opportunities for participants to interact and develop relationships, we created a WhatsApp chat for each group. Despite challenges for participants to use ICTs and participant-stated preference for in-person meetings, the results demonstrated that participants overwhelmingly endorsed these technologies as promoting access, participation, engagement, and satisfaction. Zoom/WhatsApp created a valuable environment both as a method for conducting research with this population, but also as part of the intervention for immigrant women to support and learn from each other. ICT adaptations have now permanently changed the way we conduct community-engaged health research. [ABSTRACT FROM AUTHOR]
