As a result of the confinement provoked by the COVID-19 pandemic, educational institutions around the world employed various remote strategies to continue with the students' educational process; however, given the long period of confinement, various affectations emerged, mainly related to emotional, physical health, social, academic, and technical issues. The objective of this research was to determine the main effects that students at a university campus in Mexico had while studying in the distance mode during the confinement, as well as to identify if there is a difference between the effects found among the students of the different disciplinary areas that conform the campus. A total of 475 students were surveyed and the means of the responses were compared, showing that the main effects were emotional, physical and academic, as well as that there are significant differences in three of the six disciplinary areas investigated. It was also found that the social affectation was not significant. The findings confirm that four of the five most frequent affectations found in the literature were also present in the university students of the Campus in all their disciplinary areas, which confirms that it is essential to have holistic visions of distance learning in order to face the challenges that educational systems will face in the future.

This review explores the significance of consuming edible insects, as well as their use in the food industry, agro-industry for animal husbandry, agricultural fertilizers and bio-pesticides, and pharmaceuticals. It emphasizes the increasing interest and relevance of this practice. The study starts by investigating the earliest evidence of anthropoentomophagy, which is the consumption of insects by humans, in the region. The review offers an overview of the consumption and utilization of insects in specific regions of the world, emphasizing their significance in various cultures and geographic areas. It also identifies the types of edible insects commonly consumed in Latin American countries, such as Mexico, and explains their preparation and consumption. Furthermore, the review assesses the nutritional value of edible insects, emphasizing their potential as a valuable source of protein, vitamins, and minerals. It also explores the various promising applications of insects, including their role in the food industry, animal husbandry, production of agricultural fertilizers and bioprotectants, and even their potential in the pharmaceutical sector. Finally, the article highlights the significance of entomophagy in Latin America by exploring its historical origins, nutritional benefits, and potential applications in various industries.

The higher education institutions (IES by its Spanish acronym) in Mexico, carried out, with certain periodicity, various actions prosecuted to evaluate, restructure or modify their study programs; in whose curricular organization, must ensure and guarantee the quality of education to enable the graduates respond professionally to the demands of the current times. To safeguard the teaching quality, the (IES) have created new figures that are understood in essence, nevertheless the university teachers face a different reality at the time to put them into practice, as is the case in some of the degrees in our University campus. This work is a reflection that enables strategic proposals for the development of the tutorial activity on the basis of considerations on the tutorial task that is currently within the Bachelor's Degree in Communication Sciences of the Faculty of Human Sciences comparing with the proposals which expresses the National Association of Universities and Higher Education Institutions (ANUIES by its Spanish acronym) about tutorials and his practice in the day to day work of university teaching.

The increased interest on measuring violence in romantic relationships has led to the identification of some risk factors for intimate partner violence (IPV) in its different forms. Some of them are often present from the onset of the relationships. However, little attention has been paid to the engagement period. This might be, in part, due to the cognitive dissonance that hinders partners reporting intimate violence when they are planning their wedding. The purpose of our study is to test the association between the individual perception of relationship power imbalance (RPI)—a possible indirect measure of intimate violence—and known predictors of IPV. To test this hypothesis, a total of 254 premarital couples taking part in a dynamic prospective cohort study completed a questionnaire with questions about the perception of RPI and referred predictors of IPV. Results showed a positive correlation between the perception of RPI and known predictors of IPV. These findings suggest that RPI is a powerful indirect measure to detect situations that might imply a mild form of IPV and that could evolve into stronger presentations of violence later in marriage. Noticing the presence of RPI before marriage could encourage the prevention and development of personal and relational strategies to avoid the consolidation of violent dynamics within the marital relationship.

Equine infectious anemia (EIA) is a highly infectious disease in members of the Equidae family, caused by equine infectious anemia virus (EIAV). The disease severity ranges from subclinical to acute or chronic, and causes significant economic losses in the equine industry worldwide. Serologic tests for detection of EIAV infection have some concerns given the prolonged seroconversion time. Therefore, molecular methods are needed to improve surveillance programs for this disease. We attempted detection of EIAV in 6 clinical and 42 non-clinical horses in Nuevo Leon State, Mexico, using the agar gel immunodiffusion (AGID) test for antibody detection, and nested and hemi-nested PCR for detection of proviral DNA. We found that 6 of 6, 5 of 6, and 6 of 6 clinical horses were positive by AGID, nested PCR, and hemi-nested PCR, respectively, whereas 0 of 42, 1 of 42, and 9 of 42 non-clinical horses were positive by these tests, respectively. BLAST analysis of the 203-bp 5′-LTR/ tat segment of PCR product revealed 83–93% identity with EIAV isolates in GenBank and reference strains from other countries. By phylogenetic analysis, our Mexican samples were grouped in a different clade than other sequences reported worldwide, indicating that the LRT/ tat region represents an important target for the detection of non-clinical horses.

Background. Spatial genetic structure (SGS) analysis is a powerful approach to quantifying gene flow between trees, thus clarifying the functional connectivity of trees at population and landscape scales. The findings of SGS analysis may be useful for conservation and management of natural populations and plantations. Pinus cembroides is a widely distributed tree species, covering an area of about 2.5 million hectares in Mexico. The aim of this study was to examine five natural seed stands of P. cembroides in the Sierra Madre Occidental to determine the SGS at population (within the seed stand) and landscape (among seed stands) levels in order to establish guidelines for the conservation and management of the species. We hypothesized that P. cembroides, in which the seeds are dispersed by birds and mammals, creates weaker SGS than species with wind-dispersed seeds. Methods DNA fingerprinting was performed using the amplified fragment length polymorphism (AFLP) technique. In order to estimate the SGS at population and landscape levels, we measured the geographical (spatial) distance as the Euclidean distance. We also estimated the genetic distances between individuals using the pairwise kinship coefficient. Results The results showed non-significant autocorrelation in four out of five seed stands studied (i.e., a mainly random distribution in the space of the genetic variants of P. cembroides at population level). Discussion SGS was detected at the landscape scale, supporting the theory of isolation by distance as a consequence of restricted pollen and seed dispersal. However, the SGS may also have been generated by our sampling strategy. We recommended establishing a close network of seed stands of P. cembroides to prevent greater loss of local genetic variants and alteration of SGS. We recommend seed stands of P. cembroides of a minimum width of 225 m. [ABSTRACT FROM AUTHOR]

We present a classification of the types of censorship of media to frame the various issues that journalism and freedom of expression face in Mexico, which mainly include the role of the State in preventing or enforcing censorship, the monopoly of a few corporate groups that control most of the mass media and dictate fixed editorial lines throughout all of them, the effect of violence on journalism and the issues that are emerging around the freedom of expression in social media.

Accurate quantification of branch volume in trees is important for sustainable forest management, especially as these fractions are increasingly used for bioenergy, and for precise forest CO2 quantification. Whereas a large focus has been placed on the compatible estimation of tree taper and bole volume with and without bark, little effort has been made to develop models that allow a simultaneous prediction of these variables together with tree branch volume. In this study, 595 Pinus cooperi trees and 700 Pinus durangensis trees were sampled in pine-oak forests in the Sierra Madre Occidental, Mexico. A compatible system for predicting two segmented taper functions, over and under bark; the corresponding merchantable volumes; coarse branch volume and whole-tree volume was fitted using a modified continuous autoregressive structure to account for autocorrelation. The proposed compatible equations explained more than 97% of the observed variability in diameter over and under bark, volume over and under bark, and total tree volume and more than 64% of the observed variability in branch volume in both species. The method described can theoretically be replicated for any tree species, thus providing a better understanding of the patterns of volume distribution by components, potentially improving carbon accounting system and forest bioenergy planning.

Introduction: Mathematical models and field data suggest that human mobility is an important driver for Dengue virus transmission. Nonetheless little is known on this matter due the lack of instruments for precise mobility quantification and study design difficulties. Materials and methods: We carried out a cohort-nested, case-control study with 126 individuals (42 cases, 42 intradomestic controls and 42 population controls) with the goal of describing human mobility patterns of recently Dengue virus-infected subjects, and comparing them with those of non-infected subjects living in an urban endemic locality. Mobility was quantified using a GPS-data logger registering waypoints at 60-second intervals for a minimum of 15 natural days. Results: Although absolute displacement was highly biased towards the intradomestic and peridomestic areas, occasional displacements exceeding a 100-Km radius from the center of the studied locality were recorded for all three study groups and individual displacements were recorded traveling across six states from central Mexico. Additionally, cases had a larger number of visits out of the municipality´s administrative limits when compared to intradomestic controls (cases: 10.4 versus intradomestic controls: 2.9, p = 0.0282). We were able to identify extradomestic places within and out of the locality that were independently visited by apparently non-related infected subjects, consistent with houses, working and leisure places. Conclusions: Results of this study show that human mobility in a small urban setting exceeded that considered by local health authority’s administrative limits, and was different between recently infected and non-infected subjects living in the same household. These observations provide important insights about the role that human mobility may have in Dengue virus transmission and persistence across endemic geographic areas that need to be taken into account when planning preventive and control measures. Finally, these results are a valuable reference when setting the parameters for future mathematical modeling studies. [ABSTRACT FROM AUTHOR]

National Parks in Mexico are home to small communities. Whereas productive activities are by definition prohibited within park limits, restoration and conservation practices are encouraged. One way to benefit the inhabitants of these parks is to promote conservation practices that can be productive at the same time. This paper describes and evaluates the practice of regular pruning of Abies religiosa (HBK) in the Cofre de Perote National Park as both a measure to prevent forest fires and a means to obtain the raw material for the manufacturing of Christmas wreaths. Under the guidance of our university research team, over a period of 3 years, local women pruned trees over a total area of 36 ha and used part of the pruning waste (2.71 %) to make the wreaths. The income generated from pruning and from sale of the wreaths contributes significantly to household expenses. We describe the collaboration between the local Women's Group, the academic team, a federal government agency and the local authorities. The study concludes that the laws regulating national parks in Mexico should specifically stress the importance of allowing productive activities compatible with conservation. [ABSTRACT FROM AUTHOR]

The effect of varying fat content in Oaxaca cheese, a typical pasta filata, on microstructure was described. Microstructure of cheeses was analysed by scanning electron microscopy (SEM) and light microscopy (LM) in nondehydrated and dehydrated samples. In nondehydrated samples, protein fibres were wide and compact in fat-free cheese, and big serum channels were approximately 100 μm in width. Width of protein fibres and size of channels decreased as fat content increased. Small channels seemed to be occupied only by fat, while in big channels, water and fat were observed. LM both confirmed and supplemented the observations made by SEM, particularly the presence and distribution of fat in channels. [ABSTRACT FROM AUTHOR]

Semiarid scrubland communities are highly dynamic in terms of their species composition, abundance, and functioning, given the drastic changes in climate among seasons. Spatiotemporal patterns of saprophagous Copestylum (Diptera: Syrphidae) communities in different cactus species richness have not yet been studied, although seasonal changes and plant species richness have been shown to strongly impact the diversity and distribution of many insect communities in scrublands. We analyzed the impact of seasonality and of habitat type (disturbed and undisturbed) on Copestylum communities reared from cactus species at the Barranca de Metztitlán Biosphere Reserve, in central Mexico, by comparing their community structure between seasons and habitats, and assessing the contribution of diversity components for the total diversity of this genus. We also measured patterns of temporal niche overlap among hoverfly species considering their breeding medium. Seasonal variation influenced Copestylum community composition most significantly. Species richness and abundance of Copestylum were higher in the rainy season. Additive partitioning of diversity showed that the main component for species richness is beta diversity between seasons. We detected high niche overlap during the dry season and low overlap during the rainy season. This study provides evidence of temporal shifts in xeric hoverfly communities and suggests that the Copestylum species partition resources over time. [ABSTRACT FROM AUTHOR]
