Resilience to climate change: a literature review of the concept and its implications
This research reviews the literature on the concept of resilience to climate change, with the aim of offering an overview of this area of knowledge. In addition, it seeks to identify the relevant dimensions, keywords, objects of study and associated methodological theories (approaches). In the exhaustive search for scientific works on "resilience and climate change", 195 publications were found, the majority are on climate and urban resilience with a theoretical, reflective and informative approach. The results show that interest in resilience to climate change has increased, mainly in the countries of the United States, Mexico and Spain. On the other hand, the research areas in which most work has been done with resilience to climate change since 2013 is agroecology, agronomy, economics, social, education, environment, socio-environmental and urban. Likewise, the most common keywords in the research are: adaptation, vulnerability, urban, environmental and risk. Few works on resilience to climate change were found where the object of study is drinking water, irrigation systems, tourism, wine, medium and small businesses, corn, urban housing and fauna. Therefore, it is concluded that there is still much work to be investigated in this line of research.

Good Living and Living Well as alternatives to the concept of conventional development
In Ecuador and Bolivia, a debate has begun around Good Living and Living Well (BV and VB), which has its origin in the words Sumak Kawsay and Suma Qamaña (expressions of the Kichwa and Aymara language). The importance of BV and VB lies in the fact that it can be conceived as an alternative category to the concept of conventional development; For this reason, in this article a documentary review of its main exponents was made to know the bases that support said ideology. It should be noted that this is based on the vision of life of the Andean community and its origin dates back to the indigenous movements of the late twentieth century and the assemblies that led to the current constitutions of Bolivia and Ecuador, in 2008 and 2009 respectively. The BV and VB proposal sets guidelines for building new ways of relating to society and nature. In addition, it works as a platform where other perspectives that coincide with this life project can come together.

Architectural language and social representations of urban insecurity
This article exposes how insecurity has impacted the configuration of the territory, generating armored and defensive architectures that use the privatization of urban space as a "symbol" of security, and how the different social messages of deterioration and abandonment define a vast perception of insecurity in certain urban environments.

Smoothed Particle Hydrodynamics as a tool to mitigate structural damage due to fluid-structure interaction
Computational simulations were performed using the smoothed particle hydrodynamics method to study the interaction between a fluid flow and a solid structure, resembling a bridge and a residential building. The aim was to demonstrate that the use of computational fluid dynamics technique is a valuable tool for evaluating the stresses experienced by the structure during fluid-structure interaction. Two arbitrary case studies were considered where velocity and stress fields were obtained to illustrate which areas experience greater stress than the rest of the infrastructure. This provided numerical-graphical technical support to recommend structural reinforcement or modification of the structural design, intending to mitigate potential structural damage primarily caused by fluid flow derived from hydrometeorological phenomena or tsunamis.

Bayesian estimation of the parameters of the randomized ordinal probit regression model
A large number of papers estimate the prevalence of a randomized binary variable, but few model the effect of non-sensitive covariates on a randomized binary response variable. A small number of papers study a sensitive ordinal variable, and there are no papers that model the effect of non-sensitive covariates on a randomized ordinal response variable. The objective of this work is to use the Bayesian approach to measure the effect of non-sensitive covariates on a randomized ordinal response variable obtained under the forced response design and evaluate the performance of the proposed estimators. Four prior distributions were used: Double exponential, Normal, t and Cauchy. A simulation was performed to compare the Bayesian estimators studied considering two numbers of categories of the randomized ordinal response variable, two sample sizes, and two numbers of non-sensitive covariates. The comparison criteria were the mean squared error, the length and the coverage of the credible intervals. The proposed Bayesian estimators adequately estimated the true parameters of the randomized ordinal probit regression model, even when the forced response design induced by the Hopkins randomization device was used to produce a randomized ordinal response variable. The Bayesian estimator using the double exponential prior distribution was the best in terms of the criteria used.

Effect of pruning and fertilization on flowering induction in guava (Psidium guajava L.) in the municipality of Cuernavaca, Morelos
The effect of cultural tasks such as pruning and fertilization on floral induction in guava (Psidium guajava L.) was evaluated. The 60-60-30 fertilizer formula was used, applied 50% at the time of pruning, 50% at the beginning of flowering and irrigated by dripping. The trial was set up under a randomized complete block design with factorial arrangement. Treatments T1 without pruning and without fertilization, T2 with pruning plus fertilization, T3 with pruning and without fertilization, T4 without pruning with fertilization, in five blocks. As response variables: shoot diameter, shoot length, number of flowers per shoot and number of fruits per shoot, were subjected to an ANOVA and LSD test (α=0.05). Treatments T2 and T3 did not show significance in the expression of the variables emitted shoot diameter, shoot length, number of leaves per shoot and number of flowers per shoot, exceeding the expression of trees subjected only to fertilization (T4) and to the trees of the control treatment (T1), without finding significant differences between the latter. Pruning and fertilization had a clear effect on the induction of foliar and floral buds, the highest flower and fruit production occurred in the pruning-only treatment (T3) with 4.8 fruits/bud/year, followed by the pruning plus fertilization treatment. (T2) with 2.1 fruits/shoot/year. The treatment only fertilization (T4) and the control treatment with 1.2 and 1.6 fruits/shoot/year. The four treatments followed the statistical trend indicated above. The branches of the trees facing east and west were the branches with the highest set of fruits. Pruning and fertilizing cultural work is an alternative that will allow the harvest to be focused on windows of market opportunity. The production is concentrated in the branches facing east and west, it will help the establishment of the guava orchards

Fischer decomposition by generalized inframonogenic functions
In this note we will define a new fractional Dirac operator constructed with a structural set φ to subsequently obtain a Fischer decomposition in terms of (φ,ψ)-inframonogenic functions. This Dirac operator and the fractional variable generate a Lie superalgebra isomorphic to osp (1|2). Such an algebra occurs in superconformal minimal models and in supergravity quantization. As a consequence of the absence of commutativity some features will be shown which differ generally from those known in the classical harmonic case.

Civil society and non-electoral participation in Guerrero
The study explores the attitudes and values that underline the political participation of Guerrero citizens. Two questionnaires were designed to collect data: The first was administered using focus groups (FG) to members of civil society associations, members of business chambers, and professional associations, distributed across the state's seven regions; the second included semi-structured questions to researchers, former electoral officials, and relevant political actors. The study sought to identify the main reasons that prevent citizens from fully exercising their political rights. The data obtained show the existence of factors, some of them structural, that promote or inhibit political participation. The information obtained provides elements that can contribute to the design and development of public policies that strengthen Civic Culture in Guerrero.

Exploring the Frontiers of Artificial Intelligence: Impact, Challenges, and Future
This paper attempts to detail the evolution of Artificial Intelligence (AI) in various fields, revealing how it has altered the interrelationship between human ability and technology. Its objective is to analyze the frontiers of AI, its impact, challenges, and future in different sectors and society in general. It is based on a mixed methodological approach carried out through a systematic review of recent studies, which includes 88 investigations found according to the search criteria, of which 10 are analyzed. The results indicate that, although AI has revolutionized many sectors such as education and healthcare, it has given rise to moral dilemmas such as algorithmic bias and data privacy issues. With these findings, it is concluded that AI has brought about notable progress in many areas of knowledge; however, regulation on data control is necessary to maintain a balance between technological innovation and ethics.

Teaching materials in emergency remote education: perceptions from students of the Higher School of Educational Sciences
Teaching materials are one of the main tools for learning; their diversity and adaptability are relevant to meet the needs and contexts of students. Emergency remote education involves three situations: first, living a contingency condition that makes it impossible for students to attend face-to-face classes; second, considering virtual spaces as alternative training elements, and third, that in these environments the accessibility conditions are different and even hostile, because the digital divide in the state of Guerrero is latent. The research aims to identify the teaching materials used in remote emergency classes due to Covid-19, in the Bachelor of Education Sciences. From a positivist paradigm with a quantitative approach, the descriptive case study answers the following research question: What are the characteristics of the teaching materials used in a remote emergency situation? Beyond knowing the materials, the research aims to characterize them, since remote emergency education has certain particularities that lead to changes and adaptations that conventional materials may have. From the perceptions of students in education, the work accounts for training needs and opportunities to be better prepared to face academic vicissitudes with appropriate educational materials in any eventuality. The results show that various materials were used, both to facilitate teaching content and to demonstrate learning: videos, infographics, conceptual maps, synoptic tables, in addition to traditional ones such as books and notes. Characteristics such as the diversity of formats, intentionality, character, meaning and potential of the material to generate learning and motivate its consultation were relevant findings that allow us to glimpse lines of work and research for its continuous improvement.

Perspective on the management of urban solid waste in Xaltianguis, Guerrero
In Mexico, municipalities present challenges for waste management, due to economic development and the proportion of the urban population. Such waste must be managed to avoid contamination of the environment and natural resources. The objective of this research was to explore and analyze social perceptions of management practices in their different stages (generation, separation, collection, reuse and disposal) in Xaltianguis, municipality of Acapulco de Juárez, Guerrero, México. 389 questionnaires with 51 items were applied to people over 18 years of age. The results showed that people are willing to separate, collect and reuse waste in their homes, which is related to aspects such as: gender, age and level of education. The management of waste in this town is a challenge for the municipality, so the population tends to take actions to manage waste. It is concluded that joint work is necessary between the municipality, the actors involved, the private sector and the population for the coordination of actions supported by reliable diagnoses for the efficient use of available resources.

Impact of the support of the National Network of Ethnobotanical Gardens on the living Bursera collection of the Botanical Garden of the Autonomous University of Guerrero
The document describes how the support of CONAHCYT, through the National Network of Ethnobiological Gardens (Renajeb), has impacted the increase of the collection of the Bursera genus in the Botanical Garden of the Autonomous University of Guerrero (JB-UAGro). The species of the Bursera taxon, known locally as copales and cuajiotes, are plants that live mainly in deciduous tropical forests, of which they are important elements in its structure and physiognomy. In addition to their ecological relevance, they also have a cultural relevance, since they are used in traditional medicine, living fences, ritual uses and for the elaboration of crafts. Among the objectives of JB-UAGro is to promote knowledge of the genus through the conservation and permanent exhibition of specimens of its species. Through research projects, Renajeb has facilitated the increase of specimens of species that were not represented in the living collection of JB-UAGro, by expanding the geographic range of collection in municipalities of Guerrero, which has allowed a more complete representation of the diversity of the genus. Specimens of 14 species that were not part of the collection have been incorporated into the collection, which represents an increase of 77.7%. Another relevant support from Renajeb was the hiring of a specialized taxonomist for the precision in the scientific identification of both the specimens already established in the collection and the new additions. Currently, of all the member gardens of Renajeb, JB-UAGro stands out for the collection of specimens of 32 “ex situ” species of Bursera. The support provided by Renajeb strengthens this university garden in aspects related to research, conservation and dissemination of biological and cultural knowledge of the Bursera taxon.

Perceptions about the exploitation of the Nexpa aquifer in the community of El Pericón, municipality of Tecoanapa, Guerrero, Mexico
In this work, the water problems presented by the community of El Pericón located in the municipality of Tecoanapa in the state of Guerrero were analyzed, based on the perception that the inhabitants have about the aquifer. The information was obtained from interviews of different social actors. The results showed that the majority of participants in the study perceive that the community's aquifer is only exploited by the lack of surface water in springs and streams, also by the prolonged shortage of water in the distribution network, and by the trade of water. The factors with the greatest impact on the exploitation of the aquifer are social and economic, since the demand for self-sufficiency is increasing. Another pressure factor is the extraction of water for sale, an activity carried out by local merchants and resellers who distribute water in neighboring communities. Deforestation and fires are also pressure factors for the aquifer. It is necessary, through of alternatives that allow homes to capture rainwater, carry out wastewater sanitation, reforest the area and carry out actions for the natural recharge of the aquifer. Furthermore, it is important to reduce, with similar alternatives, the pressure placed on the aquifer when other communities buy water extracted from the community where the research was carried out.

Community census of urban trees and their carbon storage estimation: a citizen science exercise in Guadalupe Victoria, Durango, Mexico
Urban trees play a crucial role in environmental sustainability, contributing to climate change mitigation, air quality improvement, and biodiversity promotion. However, the lack of detailed information on tree species in urban areas complicates the effective management and conservation of these resources. Often, gathering this information requires considerable human resources for field data collection. To address this issue, this research presents a citizen science exercise for urban tree census and the estimation of its ecosystem service of carbon storage, using the city of Guadalupe Victoria, Durango, Mexico, as a case study. The city was sampled by zones, conducting a count of trees and arboreal shrubs in urban green areas and recording their common and scientific names. Subsequently, carbon storage in the tree- covered area was estimated using the i-Tree Canopy software. As a result, a total of 4,503 specimens were surveyed. The most prevalent tree species were huizaches (Vachellia farnesiana), jacarandas (Jacaranda mimosifolia), truenos (Ligustrum lucidum), mezquites (Prosopis juliflora) and species from the Pinaceae family and Casuarina. Carbon storage in the tree-covered area was estimated at 5,678.9 tons of carbon. This exercise is expected to serve as a useful and replicable example for generating information that guides conservation and management actions for urban trees, as well as fostering citizen participation.

Specification of an electronic entrepreneurship model
The digital entrepreneurship involves the emergence of empathy, commitment, innovation and satisfaction to make a program to build a global digital village process. In this scenario, state deregulation looming citizen participation through electronic devices in order to generate ideas for Human Development. But in either scenario, as digital exclu-sion or inclusion, differences between resources and groups exacerbate asymmetries between individuals. This paper argues that in both contexts, digital gap or digital village, the entrepreneurship generates human development, but also intensifies the helplessness of people exposed to harassment. A review of theoretical and conceptual frameworks and findings reported in the state of knowledge warns that entrepreneurship is generated by perceptions of opportunity, that linked to expectations associated with compatibility, usability, and users, develop asymmetric relations between ciber-users. Therefore, we propose a model for study of these phenomena, in order to open the discussion about relevance of electronic devices in the dissemination of equity.

Environmental education and sustainable development
Current problematic issues regarding environmental pollution, climate change and degradation of nature has derived into an increase of interest of many citizens about possible harmful consequences of these threats for nature. These current issues must be explained, and must reach the entire population, in a way that exceeds a scope of simple ex- change of information. In the same way, these issues need to become a generating process of conscience based on critical thinking that challenges current ways of thinking responsible for ecological and social deterioration. An alternative to address this global problem is environmental education, understood as a continuous process of formation of an ecological culture through management and assimilation of knowledge, attitudes, skills and values about man's relationship with nature. Within this approach, it is necessary to leave behind an encyclopedic education, decontextualized from reality, and mainly focused on cumulative theoretical knowledge, and turn into a way for education that not only is worried about how to teach, but also how to learn, and to boost development of life skills. Environmental responsibility is no longer a national or regional task, this issue is turning into a matter of global dimensions. All rich and poor countries must work together to reverse current nature degradation, because this problem is result of both, poverty and industrialization.

Citizens and council members of the coastal regions of Guerrero, Mexico, from the perspective of their political culture
This study examines, through the results of surveys on political culture, the type of political orientation that guides the behavior of citizens and members of municipal councils in the Costa Grande, Acapulco, and Costa Chica regions of Guerrero, Mexico, in their interactions with the post-transition political system. It seeks to identify the potential for these orientations to contribute to democratic governance. The political culture of citizens and council members in the coastal regions of Guerrero, Mexico, is analyzed to evaluate its influence on democratic governance. Three dimensions are studied using surveys: political interest, satisfaction with democracy, and trust in institutions and political actors. The results show that citizens' interest in politics is limited, while council members demonstrate greater involvement. Television is the primary source of information for both groups. Regarding democracy, there is an ambivalent perception: some citizens acknowledge its existence, but many express dissatisfaction or indecision. For their part, council members are viewed more favorably, although they also express criticism. Trust in institutions is uneven: citizens are particularly distrustful of political parties and local authorities, while council members show greater confidence in the various levels of government. Likewise, problems of intolerance and discrimination are detected, as well as weaknesses in public ethics and oversight mechanisms, notably the lack of understanding of their roles by some council members. In conclusion, although conditions exist for strengthening democracy, traditional political practices, institutional distrust, and low citizen participation persist, limiting its consolidation.

The role of women in agricultural systems
Agricultural development requires social actors as women, and they are who generate job force. From its basic role in the family organization and participation in agricultural activities, this study analyzes the role developed by women in agricultural production systems in the State of Guerrero. Sustained by an analysis of 398 surveys in 7 regions of the state of Guerrero, we found that most of women reach at least a primary level of study, with further limitations for kee-ping at school. Production is based on cattle breeding and the purpose of the revenue is to acquire food for family con-sumption. 77.1% said that for mothers involved in livestock activities, the most important function is to clean the barn, milking and sell milk and taking care for small animals. Family members share labor activities and women are an im-portant resource as labor force, They are usually involved in the division of labor and acquiring more income, and a higher level of revenue is related with mother´s activities. Decision of raising animals is attributed to the mother, con-sidering that when the to a traditional women

Poverty and female headship in the state of Guerrero, Mexico. Diagnostic elements
The state of Guerrero ranks third in the country in terms of female-headed households. Despite this, government agencies design their policies without considering a gender perspective. The diagnostic elements presented here highlight the need to incorporate the perspectives and interests of female heads of household into public policies, emphasizing their high presence and the poverty in which many of these women live. Based on statistical data and testimonies, it is evident that female heads of household face gender inequalities, an excessive burden of domestic work, and limited employment opportunities, which negatively impacts their quality of life. The research shows that these women often assume the role of head of household due to widowhood, separation, or abandonment, and that, although they contribute significantly to family support, their work is under-recognized. Furthermore, difficulties in accessing housing, credit, and property ownership are identified. Despite these challenges, some achieve a degree of empowerment by making decisions within the household. The study concludes that it is necessary to incorporate a gender perspective into public policies to improve their conditions and promote their economic and social autonomy.

Analysis of the Expectation, Satisfaction and Loyalty of Tourists Who Visited Acapulco, Guerrero, Mexico
This study analyzes the behavior of tourists who visited Acapulco, Guerrero, Mexico in 2013. The study was conducted using a sample of 400 tourists at 40 tourist sites. The results reveal the influence of Expectation, Satisfaction, and Loyalty on tourists who visited Acapulco during a time of crisis. The results show that, although tourists arrive with relatively low expectations, most experience a high level of satisfaction during their visit and express a strong intention to return and recommend the destination, indicating a high degree of loyalty. The study confirms that: expectations positively influence satisfaction; satisfaction influences loyalty; and expectations also directly impact loyalty. It concludes that satisfaction is a key step in generating loyalty, but it is not sufficient on its own. To strengthen this, it is necessary to create value, trust, and long-term relationships with tourists. Finally, it is worth noting that Acapulco, despite its decline as an international destination, maintains a high level of repeat domestic tourism, which represents an opportunity to improve its image and competitiveness.

Aspects to consider in the construction of an expert system for environmental quality assessment
This study analyzes aspects to consider in design of a methodology for development of an Expert System for Eval-uation of Environmental Quality [ESEEQ]. There are different models for analyzing environmental quality, but it is noteworthy that most of these methods were developed for specific projects and may be complicated to generalize their uses. Modelling architecture of the computer system is based on ERFCA technical variables. These variables must be represented by significantly structured data, easily usable, and must be integrated into the process and must be readily available, allowing an accurately technical model of with a high degree of reliability. Interaction of environmental sys- tems and computer systems that integrates environmental computer information technologies, and environmental sus-tainability focused on contribute to environmental conservation, could generate new knowledge. This model promotes diffusion and dissemination of scientific knowledge favoring a change in habits arising, and behaviors of citizens in order to benefit our environment.

Influence of HgCl2 on the expression of fibrillarin (Fb) in germination of Phaseolus vulgaris LFibrilarina
Mercury (Hg) is now considered an environmental contaminant of high risk to human health and the environment. The toxicity of mercury and its compounds has been extensively documented, but the molecular mechanisms of tox- icity have not been fully clarified. The aim of this study was to analyze the effect of mercuric chloride (HgCl2) in the expression of Fb, as a biomarker of early effect of mercury contamination, using as a model of Phaseolus vulgaris L. seeds, black variety Jamapa . Fibrillarin (Fb) one of the main components of the nucleolus, is an essential ribonucleo- protein phylogenetically conserved in ribosomal RNA processing (rRNA) in partnership with small nucleolar RNAs (snoRNAs), along with other basic functions in biological systems. The expression of Fb was monitored by protein electrophoresis (SDS-PAGE) and Western blot of embryos beans during early stages of germination with different times 0, 6, 12, 18, 24 and 30 hrs and exposure 10 , 20 and 30 µM HgCl2. The results obtained by Western blot re- vealed that inhibits mercury nucleolar protein expression Fb from a minimum concentration of 10 µM HgCl2 after 18 hours after the start of germination. These observations demonstrate that the protein is usually a mercury target mole- cule capable of inhibiting its expression. This particular selectivity of HgCl2 by protein may constitute the biochemi- cal basis for considering Fb as early biomarker of contamination by HgCl2 Additionally the results show that the inhi- bition HgCl2 and caused marked delay seed germination gradually, as the dose of mercury is increased to 30 µM HgCl2.

188 C/A polymorphisms in the LEP gene and K109R in LEPR in a group of mother-neonatal pairs and their association with gestational weight gain and neonatal anthropometry
Genes, environmental factors, and lifestyle play an important role in the development of obesity. Leptin, through the action of its receptor, regulates weight gain by decreasing food intake and increasing energy expenditure; it is also an important hormone in embryonic and fetal development. The objective of this study was to determine the genotypic frequency of the -188 C/A polymorphism in the LEP gene and the K109R polymorphism in the LEPR gene in mothers and their newborns and to evaluate their relationship with maternal gestational weight gain and anthropometric parameters in newborns. Ninety-one mother-newborn pairs from the state of Guerrero, Guerrero, and attending the Hospital de la Madre y el Niño Guerrerense were included. All participants underwent body composition analysis, and maternal gestational weight gain was classified according to the criteria of the Institute of Medicine (IOM) of the United States. Quantitative determination of leptin and its soluble receptor (sLEPR) was performed using the ELISA method (Biovendor) on maternal peripheral blood and umbilical cord blood samples. The -188 C/A and K109R polymorphisms were genotyped by PCR-RFLP. Maternal and umbilical cord leptin levels were found to be related to gestational weight gain and neonatal anthropometry. The K109R polymorphism in the leptin receptor was associated with gestational weight gain, placental weight, and neonatal anthropometry.

Evaluation of REST expression levels in lung cancer cell lines: potential use as a diagnostic tool
The aggressiveness of small cell lung cancer (SCLC) is associated with the ability of cancer cells to metastasize. Previous studies have demonstrated the role of REST (RE-1 Silencing Transcription factor) in regulating the neuronal phenotype of SCLC, highlighting its importance as a potential diagnostic target. The aim of this study was to determine whether there is differential REST expression among cell lines from different stages of SCLC, using protein analysis via Western blot. The results showed differential expression of canonical REST in the different cell lines, demonstrating decreased levels and the appearance of truncated REST (tREST) in advanced stages of cancer. These studies constitute some of the first evidence of REST as a potential biomarker for SCLC.

Avifauna of Tierra Colorada in the municipality of Juan R. Escudero, Guerrero, Mexico
The state of Guerrero harbors a high diversity of bird species, ranking seventh nationwide in terms of avian richness. Unfortunately, significant knowledge gaps persist in certain regions regarding its avifauna. Therefore, the development of biotic inventories It is crucial in understanding its biodiversity and can serve as input for species and habitat conservation strategies. This study presents a description of the avifauna recorded in Tierra Colorada, municipality of Juan R. Escudero. Fieldwork was conducted January, February, April, July and August, in 2024. Five observation transects were established and surveyed across areas with natural vegetation and zones influenced by human settlements. The composition of bird species was analyzed in terms of endemism, seasonality, conservation status, and trophic guilds. A total of 88 bird species were recorded, representing 14 orders and 32 families. Sixteen species are endemic to Mexico, five are listed under some risk category according to Mexican laws, and two species are included on the red list of the International Union for Conservation of Nature. Regarding migratory status, 82% of the species are residents, 16% winter migrants and the remaining 2% are summer or transient migrants. The most represented trophic guild was of insectivores (49%) followed by granivores (19%). Our results reveal a significant avian richness in the Tierra Colorada town, underscoring the value of biotic inventories and the urgent need to implement conservation strategies for the species present in the region.
