A bibliometric analysis is carried out on scientific articles referring to Mexico on cybersecurity issues, published between 2015 and 2020, indexed by Sciencedirect, Redalyc, and Dialnet. The study takes into consideration indicators such as productivity per year, per journal, per institution and per author, as well as the thematic content of the texts. From the 18 papers analyzed, the detected research trends suggest a majority contribution from researchers affiliated to universities, as well as the association of cybersecurity issues and the technologies involved in cyberspace with social topics.

The purpose of this paper is to analyze the fiscal incentives and public financing destined to the promotion of Workers' Cooperatives in Mexico, as well as the participation of cooperatives in activities that may represent transgressions to the fiscal and labor laws of our country. The results show that the economic crisis of the 1980s forced a change in the economic model and cooperatives were relegated from public policies. The relationship with the State fractured again in 2013 when cooperative companies were accused of fraudulent operations to avoid paying federal taxes, as a consequence, special taxation regimes were eliminated and public financing was reduced. However, the information published by the country's administrative authorities does not provide evidence to ensure that in the last 11 years the cooperative organizations have constituted a risk factor for federal public finances and the labor stability of workers. This research applies a mixed method, which means the combination of quantitative and qualitative research methods and techniques. In the first case, the hypothetical-deductive method is used, and in the second, grounded theory and hermeneutic triangulation. The data come from the tax agency's web page and direct consultation with the institute responsible for providing public information to citizens. [ABSTRACT FROM AUTHOR]

The objective of this paper is to show the way in which the educational policies implemented in Higher Secondary Education (EMS) in Mexico, led to the omission of the Federal High Schools for Cooperation (PREFECO for its acronym in Spanish) as a public subsystem. This omission had repercussions in the closure of schools and exacerbated the precarious working conditions of the teachers who work in that school subsystem. The paper analyzes the policies directed at the EMS during the 2008-2019 period in order to identify the causes that originated the main changes in the subsystem. The case of the PREFECO's of the state of Morelos is contextualized and the labor conditions of their teachers. For the analysis of the official documents, some guidelines of the historical-descriptive method were retaken. To contextualize the conditions of the teachers, a questionnaire was applied and descriptive statistics were used for the analysis. [ABSTRACT FROM AUTHOR]

In Mexico, during the 2012-2018 six-year term, the National Crusade against Hunger (CNCH) was implemented, in which social participation played a central role in combating the lack of access to food and promoting social welfare. With the creation of Community Committees and the support from promoter staff, this strategy aimed to strengthen and ensure the active and constant involvement of the population; however, there were a number of factors that had an impact on the difficulties in achieving sustained community participation. The objective of this paper is to show the factors that limited social participation in the implementation of the CNCH in Ciudad Juarez, Chihuahua, Mexico, through the voices of the implementing staff.

This paper exposes the limits and possibilities of educational researchers' training in Mexico concerning the dissemination of science. From the criticism of these formative processes, it turns evident the scarce professional preparation of the consolidated researchers, as well as of the novices, to establish a plural and open dialogue with all the strata of Mexican society. The idea that scientific knowledge is for the consumption of academic elites within the educational field is still upheld, and not the opportunity to debate, from different points of view, regional educational problems. Based on this, scientific journalism is proposed as the primary activity for the social communication of science to build more equitable scenarios for making better political decisions in and for our National Educational System.

This paper has the purpose to analyze to what extent TV series produced nowadays mostly on digital streaming platforms, and whose main topics focus on drug dealers' lives (narcoseries), have constituted one of the most 'fashionable' trends on TV production lately, both in terms of viewer figures and audiences' perceptions. Most of them, especially in Mexico, are linked to a group of political and social facts which, undeniably, lead many audiences to perceive a transposition of roles in these productions over the traditional duo villain-hero. Thus, viewers tend to relate the figure of a corrupted State to the villain one, while criminals are identified as heroes. Nonetheless, such perceptions find historical roots in Mexico's and Latin America's questionable governmental policies, which have direct effects on the State's condition of anomie. All these aspects together could lead, not just viewers but actual citizens, to lessen -and ultimately justify-real and patent criminal acts. [ABSTRACT FROM AUTHOR]

This paper is a reflection on the relationship between the mass media and the prehispanic past of Mexico. The official discourse (archaeological, institutional) around the past has been called into question with the transition from classical media (print, film and TV) to digital media. In contemporary worlds, the established imaginary about Mesoamerica is seen resignified and confronted with other imaginaries associated with New Age groups that promote the resurgence of the Anahuac culture.

This paper shows the different forms of cultural resistance that some people belonging to original cultures in Mexico and who have migrated to the city of León Guanajuato have. Through qualitative research and the interview technique, we recover the actions they have to preserve particular characteristics of their culture are revealed. In the first place, we will talk about what the resistance of native peoples is, and then, we analyzed the strategies used by indigenous people to preserve everything that identifies them as part of their community, culture and people even when they are outside of it, that is, knowing the way in which they resist so that their culture continues to stay alive wherever they decide to go.

This paper presents a review of the psychological, social and emotional effects of social isolation. Its objective is to reflect on this measure taken during the pandemic, focusing on the psychological consequences. On the one hand, it is based on official speeches, critical views and mental health research. On the other hand, a study is made on the subject in Mexico, in which opinions, practices and the cognitive, emotional, behavioral and relational impacts are addressed. This is done through a bibliographic and documentary review, as well as surveys, questionnaires and interviews, for the country and for Mexico City. As a result, the consideration between benefits and risks in general is presented. In particular, a favorable assessment from the population, a relative follow-up, an accumulation of unpleasant feelings, psychological disorders, as well as changes in habits, activities and relationships.

The objective of this paper is to evaluate whether the low-carbon transport strategy (subway, rapid transit bus system -Macrobús-, trolleybus, and shared bicycles) implemented in the Guadalajara Metropolitan Area (AMG) from 2000 to 2019 improves air quality. Sustainable urban mobility is the movement of people in cities in a way that generates the least impact on the environment. We analyze three actions of government intervention in the same sense. This is the first study for Guadalajara, the third-largest city in Mexico. We use robust Newey-West estimators and endogenously model pollution disruptions using the Bai Perron approach. Our results suggest that this type of public transport reduces SO2, NO2, O3, and CO, though we find an increase in PM10. We also identified that when the service of the first line of the Bus Rapid Transit was consolidated CO, O3 and PM10 decreased. In addition, the improvement in the connectivity of the bus network with the subway means that only NO2 diminished. Finally, the entry into operation of the shared bicycle program reduced PM10, while increasing O3 and in SO2. In short, sustainable urban mobility is an alternative to making the transit of people efficient, while mitigating air pollution in the AMG. [ABSTRACT FROM AUTHOR]

This study analyses the epistemic functions of images in the geographic and sociological discourses on poverty habitat in the megacities of the global south by focusing on Mexico city. Based on a conceptual and methodological review of art history from Bildwissenschaft perspective (visual studies), this paper aims to examine the poverty habitat by describing its typologies, patterns, encodings and possible effects of its visual constructions. This contribution outlines the utility of this type of research, the function of inter and transdisciplinary studies in this field and its fundamental ethic dimension. [ABSTRACT FROM AUTHOR]

This paper reflects on the gender perspective, historicization and decolonization as part of a theoretical-methodological proposal, to understand the gender systems that support masculinities and models of being a man, linked to reproduction and contemporary indigenous survival in Mexico. It constitutes a first effort of reflective analysis, on how to approach these ethnicized and gendered realities, specifically on masculinities and being a man. To do this, we start by discussing the contributions of some gender studies of men and masculinities, which do not constitute an exhaustive and updated review, but only an approximation to the growing knowledge base, to support the methodological proposal with which it seeks to understand the patriarchal, heterosexist and colonizing constraints on men and women of indigenous peoples. In this work, it is argued that re-readings of these realities are required through theoretical-methodological proposals that are sensitive to these realities, in order to stop the homogenizing views of the indigenous gendered subject, specifically the masculinized one from westernized gender systems.

This paper addresses the significance and the challenges of various decolonized practices in research and in social science training methods in Mexico and, particularly, in Chiapas, based on a Latin American approach to the field of studies conducted by intellectuals and activists involved in social movement struggles. We analyze different forms of intercultural dialogues used in decolonizing research in terms of social, ethnic and gender relationships, according to the contexts and the knowledge production of popular and indigenous movements facing politics, education and epistemic racism.

Objective: the aim of this paper is to test a sociology of welfare; that is, two analytical tools are argued to gain an understanding of the sociological content of welfare: 1) the identification of the forms of social precariousness existing in Mexico; 2) the idea of the continuum of inequality of violence and its visibility. Methodology: in defending their theory, the authors use analytical and qualitative sociology as a methodological perspective, where classical concepts of sociology function as reflexive tools to promote the elaboration of a qualitative, critical and normative thinking around the forms of precariousness and their opposite, welfare. Results: presented in two sections: 1) The emergence of violence as a structure for the precariousness of life, a section that reflects on the increase in the forms of violence and their importance when addressing the issue of well-being; 2) Analysis of the forms of social precariousness, which proposes a matrix of the main forms of precariousness that actually exist in Mexico, where the elements of the continuum of inequality of violence are identified. Conclusions: it is proposed that a qualitative sociological knowledge of social precariousness and violence, of the forms and dynamics of social action is necessary to understand the substantive meaning of welfare; useful knowledge to guide public actions in favor of welfare in democratic societies, especially to test innovation in the design of social policies.

Humanity has suffered throughout its history from different types of pandemics caused by deadly infectious diseases. Mathematical models are very useful tools to understand the dynamics of the behavior and propagation of these. Among these models are those known as SIS, SIR and SEIR. This paper presents a brief explanation of the structure of these models and its use in some pandemics. In particular, some SIR-type models without and with delays are analyzed with special interest, as well as their applications to the current pandemic caused by the SARS-CoV-2 virus. To determine the correspondence between some of the models analyzed and the data of Infectious and Recovered from Mexico reported by the World Health Organization (WHO), simulations are presented in three different time periods between the years 2020-2021. In addition, an unpublished SIR-type mathematical model with three delays is proposed as a main contribution. Finally, a discussion is given on the application of numerical algorithms to identify some parameters of mathematical models, such as ordinary least squares. [ABSTRACT FROM AUTHOR]

The General Health Law in Mexico was reformed in 2019. Since that moment the re-centralization began. Part of these process were the following actions: the Health Welfare Institute creation; the Popular Insurance disappearance; the coordination agreements signature between the national and the subtnationals governments, and the medicines consolidated purchase. These actions produced consequences in organizational functioning. Through the staff perception, this paper seeks to investigate these consecuences in a pimary healthcare organization in Nezahualctoyotl, Estado de México. Findings shouw that: 1. Second and third level hospitals were regionalized; 2. Contracts to treat diseases like cancer were eliminated; 3. Less existance of medicines and medical supplies; 4.Staff hired with fixed-term contract were given a regular contract. The re-centralization is usefull to study the health system changes.

This paper presents the results of a study aimed at identifying good practices in different systems of Vocational Education and Training (VET) around the world and in some regions of Mexico, with the purpose of designing a new vocational model for the state of Guanajuato, integrating the educational and employability dimensions, and considering the new trends in vocational systems, that have evolved from an exclusive action of educational centers, towards a new conception that integrates strategic actions carried out collaboratively by educational, governmental, social and economic actors in the region. This is a research project where a documentary analysis methodology is applied, exploring different sources and references of vocation systems that have been implemented by different countries and in other states of the Mexican Republic, to make the proposal of a new vocation model, which is the theoretical-practical reference to coordinate the actions of different actors in the region, which facilitates adequate decision-making by Guanajuato students about the continuation of their educational preparation at the high school and college levels, in addition to the best option for employment. The resulting model integrates two major conceptual axes and four subcategories in each axis, so that it is the initial input for the design of state public policies, as well as the formation of strategies in the educational, social and economic sectors of the state of Guanajuato.

This paper examines the effect of renewable energy consumption, electricity demand, sustainable economic growth and carbon dioxide (CO2) emissions on international trade in the countries of U.S. - Mexico - Canada Agreement (USMCA). To do this, unit root, cointegration and causality tests are applied, and the long-term relationship between the variables is estimated. The results suggest that the variables are integrated of different order and that there is a long-term equilibrium relationship between them. There is a positive relationship between the consumption of renewable energy, the demand for electrical energy and sustainable economic growth on international trade, while CO2 emissions reduce it. This implies that it is important to analyze energy policies that encourage increased consumption of renewable energy to boost international trade, in order to accelerate sustainable economic growth in the region. In addition, the feedback relationship between CO2 emissions and the demand for electrical energy could have important implications within the energy and environmental policy for the panel of countries in the region.

The SIR model (Susceptible-Infected-Recovered) proposed by Kermack & McKendrick aims to simulate the behavior of a contagious disease's effect-propagation, such as covid-19's; consists of a system of three differential equations, one that models the behavior of the individuals likely to acquire the disease, another equation for the infected ones and the last one for those recovered. This system has two parameters: the transmission rate ß and the recovery rate ?. The objective of the paper is to show the operation of the SIR behavior model using data from the covid-19 pandemic for Mexico, in particular, the effects of health and social containment measures on the dynamics of the model addressed. Based on daily data from the first three phases of the pandemic in Mexico, which runs from February 27 to May 17, 2021, the scenarios with and without public intervention measures was contrasted. The finding is that with sanitary and social containment measures, the rate of transmission is reduced and the curve of infected is "flattened". [ABSTRACT FROM AUTHOR]

This paper analyzes the impact of the feedback relationship that exists between inflation, its uncertainty, and the economic growth of the two main Latin American economies. A Bivariate Generalized Autoregressive Conditional Heteroscedasticity model is developed, which also allows the identification of asymmetric impacts on the conditional volatility of the product and inflation, the sample period corresponds to January 1985 to June 2019. Additionally, causality tests are developed to identify the fulfillment of the main hypotheses raised. Among the main findings is the verification of the Friedman-Ball hypothesis for both countries in most of the lags. Regarding the second hypothesis, it is found that the central bank of Mexico has presented a stabilizing behavior, while in the Brazilian case an opportunistic behavior has been identified. In the third hypothesis, no causal relationship of inflationary uncertainty towards economic growth is identified, in the case of Mexico; while, in the case of Brazil, an ambivalent causality has been identified, regarding the number of lags. Finally, in the fourth hypothesis we find results that corroborate, mainly for both economies, a positive effect from inflation on economic growth. [ABSTRACT FROM AUTHOR]

In contrast to other countries, in Mexico, there is no survey to numerically measure consumer inflation expectations. This paper reports the results of the application of a simple questionnaire that aims to obtain a first approximation of these expectations. The exercise also seeks to obtain information on the process of expectations formation through a controlled intervention, as well as to investigate which products have an effect on inflation expectations the most. Four groups were randomly formed: three that received information on past, present or expected inflation, and a control group with no additional information. Consistent with the literature, the results show that people have a higher inflation expectation than specialists. The experiment also reveals that providing information does affect and reduce inflation expectations. Finally, we find that inflation expectations depend mainly on everyday consumer products, such as food. [ABSTRACT FROM AUTHOR]

Historically, higher education is considered one of the main routes of upward social mobility. However, given the plurality of options offered by the education system at this level, there may be a distinctive pattern not only of socioeconomic origin but also of economic results after graduating from a specific higher education institution (hei), which can inhibit the promotion of social mobility through hei. Using data from the Intergenerational Social Mobility Module 2016, this paper analyzes whether the hei in Mexico promote the social mobility of their graduates. The results suggest a potential mediating effect of hei in the intergenerational transmission of wealth. This means that the wealth of the original household is an important determinant of the type of hei from which the respondents graduate, furthermore, the type of hei also explains part of the variation in the wealth of the current household of graduates. Specifically, individuals who reported having completed their university studies at the National Polytechnic Institute (ipn, Mexico) present the lowest intergenerational correlation of wealth, 0.18. In contrast, normal schools and the National Pedagogical University (upn, Mexico) have the highest intergenerational persistence rates, 0.48 and 0.47, respectively. Under these findings, it is argued that the type of hei from which individuals graduate can complement the explanation of the mechanisms of intergenerational persistence of wealth.

This paper presents various epistemological and methodological implications associated with research in dangerous regions in Mexico. Anthropological and sociological analysis methodologies were used to study violence as an object of knowledge, with new research routes and new ethnographic and information analysis strategies. These routes and strategies have been incorporated from research experiences in various dangerous territories in Mexico. This study concludes that dangerous contexts have led researchers to take new epistemological and methodological routes to address phenomena derived from criminal violence, conceptually understood within the framework of a new war between drug cartels and the state.

This paper aims to expose and analyze how LGBT students in three public universities in Chiapas, Mexico, are carrying out forms of resistance in response to manifestations of violence and discrimination. The research was based on a qualitative methodology and analyzed through a grounded-theory strategy. We found that LGBT students are not passive victims of discrimination, but rather resist in various ways, making the university a space in dispute over heteropatriarchal norms.

This paper performs a comparative analysis of the Chinese and Mexican production structures, through a descriptive study and using the methods of structural analysis on input-output tables of 1995 and 2011. During this period, the average annual per capita gross domestic product (gdp) growth in China amounted to 9.18%, while in Mexico it reached only 0.95%. Assuming that China's growth has been successful in this sense, then a mayor conclusion from this paper is that if Mexico wishes to reach high growth rates, the main element potentially useful to elaborate an efficacious strategy from China's experience is clear: To foster, from a proactive participation of the state, the development of key sectors which will constantly increase their multiplier effects, so that a mayor integration of the national economy is achieved, and the development and consolidation of the productive apparatus sufficient to support the generation of next-generation productive sectors.

The mercantile expeditions organized by Lima's commercial and political elite who traded with the Philippines and China during times of notable silver production in Potosí are studied from the last two decades of the sixteenth century until 1604. This analysis emphasizes the roles in this trade of the viceroys of New Spain, Perú, and the governors of the Philippine islands such as Francisco Tello de Guzmán. Case studies are undertaken of the networks built by Limenian neighbors Juan de Segura and Diego Núñez de Campoverde. This paper ends with an analysis of the merchandise coming from the East destined for Lima, Potosí, Sucre, and La Paz. Research for this article has been conducted in the General Archive of the Indies (Sevilla, Spain), the Peruvian General Archive, México City's General Notary Archive, and the Bolivia's Nationals Archive and Library.

In this paper, the objective is to determine whether international trade operations, cleared by maritime customs in Mexico, present fractal characteristics with long term memory. To estimate the Hurst exponent (H), the scaled rank method (R/S) was applied to 1,700 data grouped by each customs office in the country, considering as a hypotheses that long-term memory is present when H is equal or greater than 0.5 and less than or equal to 1. The results allow affirming that long-term memory does exist, with which the authorities could manage more efficiently the resources assigned to the country's maritime customs offices.

The objective of this paper is to measure the performance of formal work in two states of Mexico with different economic vocation: Quintana Roo whose main activity is tourism and Aguascalientes with mainly industrial activity. The work begins by presenting the work context in both states, and later describes the review of literature related to the performance of formal work in Mexico and Latin America. With the official data of the workers affiliated to the IMSS from 1998 to 2019, the best adjustment is identified, with the statistical parameters obtained; the monthly behavior of the first quarter of 2020 is analyzed with classical methodology contrasted with meta-analysis. The results allow us to conclude that in previous periods and during social distancing, the number of IMSS members not only remained at conventional levels, but that in several months the number of registered workers increased.

This study concentrates information from the publications that have described the occurrence of bacterial diseases and the isolation and identification of bacteria from Mexican fish. The research consisted of the systematic search of scientific papers in Pubmed, Scopus and other search engines using the key words: diseases, bacteria, fish, Mexico- in English and Spanish, without date restrictions; information from official institutions was also included. The analysis shows records of isolation and identification of several bacterial genera obtained from both clinically diseased and subclinical fish, with high frequency of opportunistic bacteria and that in the last decade the occurrence of septicemic diseases caused by emerging bacteria has been confirmed. In freshwater environment Flavobacterium psychrophilum, Yersinia spp., Weissella ceti and Lactococcus garviae have caused septicemic disease in rainbow trout (Oncorhynchus mykiss), while Francisella orientalis, Streptococcus iniae and Mycobacterium spp. have affected tilapia (Oreochromis spp.). In the saline environment, Nocardia seriolae is reported as a cause of systemic disease in red croaker (Sciaenops ocellatus). It should be noted that, despite having this information, diseases that affect or have affected fish in the country are not officially reported. To promote the development of fish farming, it is necessary to know and report its health status, in this way risks and opportunities can be identified, and control actions established.

One of the main axes of the criminal process for adolescents is the application of alternative forms of justice, which are regulated in the National Law of the Comprehensive Criminal Justice System for Adolescents in two forms of alternative solutions: Reparatory Agreement and Conditional Suspension of the Process. In this paper, some reflections are presented as a result of the work carried out between 2021 and 2022 in the areas in charge of applying the Alternative Dispute Resolution Mechanisms in criminal justice for adolescents in Mexico City, the State of Mexico and in Chiapas. Interviews were conducted with the facilitators (in the three entities) and with adolescents who participated in criminal mediation processes (State of Mexico). [ABSTRACT FROM AUTHOR]

This paper aims to show the difficulty of making the discourse of the link between professional technical education and the world of work in Mexico come true. From the analysis of several studies and, mainly, the results of an investigation of a case, it explores how the National College of Technical Professional Education (Conalep) in Aguascalientes uses linking strategies to approach the productive sector, in terms of its academic commission, support for the labor market, obtaining resources and its administrative management. The study has a qualitative approach through 12 semi-structured interviews with graduates, four with teachers, and four with school principals. The findings account for the type of school-work relationship developed by Conalep and the problems that prevent the achievement of objectives: management deficiencies, lack of technology, limitations in training and teaching practice, and, particularly, the absence of personnel, which causes non-compliance with agreements, lack of graduates' follow-up, and deficiencies in the labor market. The latter causes graduates to depend on their direct social relations to obtain work so that they do not go to their institution support offices. [ABSTRACT FROM AUTHOR]

This paper presents partial advances in the subject matter of vocational training of an investigation in progress; the objective is to analyze the importance of high school education in the life of a group of graduates in a community high school in Oaxaca. Based on a qualitative methodology with an ethnographic approach, we analyzed interviews with graduates and field research notes. The graduates' points of view are organized in two aspects: those who stay in their community and those who migrate to the city. For the first, high school has allowed them to develop a better agricultural job. Some are intermediaries of government programs, and they carry out activities with the local government; others start or work in a local business. Their economic status forces them to enroll in more than one job at a time. Those who migrate to the city mention that high school helps them perform a less physically demanding job. However, graduates decide to work in cleaning or building activities, because they can earn a better income. The conclusions discuss the results to reflect on vocational training offered to rural populations through the formal education system. [ABSTRACT FROM AUTHOR]

The crisis of disappearances in Mexico worsened in 2007, when then-President Felipe Calderon launched the war on drugs. Since then, more than 80,000 people have been reported as missing. In this panorama of violence and uncertainty, a bureaucratic apparatus tries to manage the search and mourning of families still awaiting the return of their loved ones. The following pages deal mainly with the way in which the binder -that is, the case file containing the official investigation carried out by the authorities-plays a central role in the search process. Through the voices of thirteen mothers whose daughters and sons have been disappeared, the binder is framed as a person-object, which represents a material embodiment of the victim. Through this perspective, which goes beyond the rational limits imposed by the state, this paper is based on the negative methodology proposed by the anthropologist Yael Navaro. Thus, one of the conclusions shows how through objects the disappeared persons continue to participate in the everyday life of their loved ones, as well as in the claims for justice. Finally, it is important to note that all the names of people and places have been modified. [ABSTRACT FROM AUTHOR]

The paper analyzes the socio-economic and institutional fundaments for the operation of a circular economy at the local level, and in which rural tourism is a relevant economic activity. The paper systematize the operation of some projects on ecotourism in south Mexico. It also presents some of the complementary institutional actions that are required to achieve sustainable development by applying the principles of the circular economy. The construction of a circular economy for local development requires the presence of a functional institutional framework, as this makes possible and facilitates the use of human capacities in the performance of complementary functional activities to the central project and the best use of the underlying social capital in rural communities. Rural tourism as a basis in a circular economy for local development faces challenges but offers potential that can be exploited, combining local development with the careful use of natural resources, with technological and institutional innovations that are consistent with the use of capacities. existing in rural societies.

This paper examines the narratives of thirty-three former drug traffickers and analyses how they portray drug trafficking violence. Using a discourse analysis approach, this study reveals four different meanings att ached to this violence: a) drug trafficking violence as a business; b) violence as the ground rules of drug trafficking; c) drug trafficking violence as a source of adrenaline and empowerment, and; d) drug trafficking violence linked to the cult of the Holy Dead. Identifying and understanding each of these dimensions has significant implications for policy design. As this paper shows, each dimension has distinct origins, and serves a different purpose; therefore, each of them requires a different policy-making strategy for their containment and prevention.

This paper analyzes the way in which the Mexican electorate modified the configuration of the party system after the 2018 election. By analyzing the structure and dynamics of electoral competition, it explores different dimensions to determine the magnitude of the electoral change and its translation in the party system after this election. For this purpose, the paper compares the results of the presidential and federal deputies' election in 2018, with the results of the elections held since the early 1990s. This research offers a historical perspective of the magnitude of the changes registered during this election in both the structure of electoral competition (the massive reorientation of the vote in a large part of the country, the re-concentration of power in a party, the reduction of partisan fragmentation and the changes in the nationalization of the vote of the main forces) and the dynamics of electoral competition (the emergence of the first government of the unified party from 1994, the effect of dragging the presidential election on legislative results).

Objective/Context: In this research we analyze the change in heterosexual masculinities in Argentina and Mexico during the second half of the twentieth century with a special focus on working class men who, while playing the insertive role in sex with maricas, jotas and gays, still considered themselves and were perceived by their peers to be straight. The evidence shows that, although sex between maricas and young heterosexual men occurred frequently, it was not stigmatized by straight peers, nor did it erode the perceived heterosexuality of these young men in any way. Methodology: In order to explore the representation of sexual activities from the point of view of those involved we conducted in-depth interviews and used a wide range of historical evidence, such as autobiographical literature, ethnographies, and judicial records, materials that have not previously been analyzed together. In addition to discussing self-representations, this paper also analyzes the ways in which scholars and activists from the time period perceived sex between men and the associated identitites. Originality: This paper rests on a comparative approach that helps to reconstruct regional historic and social processes in the midterm. This is the first paper that studies the problem from these straight young men's point of view, based on a novel and diverse corpus. Conclusions: In opposition to the prevailing analysis, this paper develops a counter-intuitive hypothesis: given that sex between men did not deprive heterosexual men of their identity and, instead, it constituted a way of reaffirming their masculinity, these sexual activities between men cannot be categorized as homosexual. On the contrary, the very performance of same-sex sexuality served to shape heterosexuality. [ABSTRACT FROM AUTHOR]

Objective. To determine the relative risk of a lethal outcome associated with chronic degenerative conditions in patients with COVID-19. Methods. A cohort study was conducted using electronic medical records belonging to patients who tested positive for COVID-19 on RT-PCR while receiving care as outpatients or inpatients in a social security system facility between March 2020 and March 2021. Two study groups were formed. The exposed group was divided into four subgroups, each of which was diagnosed with one and only one chronic condition (diabetes, hypertension, obesity, or chronic kidney disease); the unexposed group was obtained from the medical records of patients without comorbidities. A total of 1 114 medical records were examined using simple random sampling. Once the minimum sample size was reached, the relative risk was calculated for each chronic condition. Combinations of two, three, and four conditions were created, and each of them was included in the analysis. Results. In the absence of a chronic degenerative condition, the prevalence of a lethal outcome from COVID-19 is 3.8%; in the presence of type 2 diabetes mellitus, 15.8%; in the presence of arterial hypertension, 15.6%; and in the presence of obesity, 15.0%. For diabetes and hypertension combined, the prevalence of a lethal outcome is 54.1%; for diabetes and obesity combined, 36.8%, and for obesity and hypertension combined, 28.1%. Conclusion. In patients with COVID-19, the relative risk of a lethal outcome is 4.17 for those with diabetes, 4.13 for those with hypertension, and 3.96 for those with obesity. For two chronic conditions combined, the relative risk doubles or triples. The relative risk of a lethal outcome is 14.27 for diabetes plus hypertension; 9.73 for diabetes plus obesity, and 7.43 for obesity plus hypertension. Chronic conditions do not present alone; they generally occur together, hence the significance of the relative risks for lethal outcomes presented in this paper. [ABSTRACT FROM AUTHOR]

This work aims to know how the trend in the use of virtual spaces is, from the proposals is of incorporating technology in the teaching practice in Higher Education and knows if the level of use of information and communication technologies (ICT) affects the design and development of the proposals. In this work was used a correlative transactional methodology and the process was concurrent by complementation with a group of professors from a Mexican public university. We observed that sending and receiving documents is the most used dynamic and that, the main obstacles and difficulties are get internet accessibility and the connection speeds. The main learning activity used is creating individual documents. We concluded that, the level of skill in use of ICT that the teacher considers having does not improve the integration of technologies inside of teaching practice, and that the use of virtual spaces is oriented towards instrumental aspects (do not spent paper, automatic evaluation, and others), the possibility of structuring pedagogical proposals with integration of ICT that seek to improve the teaching and learning process in students is left aside.

Faced with popular dissatisfaction with liberal-capitalist democracy, at the beginning of the 21st century there is a governmental shift to the left in Latin America, in which Mexico is recently participating, with the arrival of the Morena party to power. The social movements that promote these political projects convey leftist utopias that seek to institutionalize themselves in political systems and public policies. However, this process of utopian institutionalization presents tensions and contradictions within the so-called party-movements. In this paper I present a methodological proposal for utopian analysis, which I apply to the "Colectivo La Calle", a group that is part of the lopezobradorista movement in Mexico. I analyze three utopias mediated by this group and find that indeed the Colectivo is mobilizing against Morena's pragmatism. This result adds to previous literature, which, given contemporary governmental experiences, questions the ability of the Latin American institutional left to overcome conservative hegemony.

Noise, smells and visual impacts are, probably, the environmental pollution problems to which the least attention is paid, considering that they are the ones that least affect the planet; However, all of them influence our quality of life and health, in addition to hindering and even preventing the full enjoyment of the Human Right to a healthy environment. Although the country has a basic legal framework that aims to prevent and control these types of pollution, there are no legal regulations that contain detailed technical standards to measure and / or limit it, except in the case of noise pollution. In this paper we present and analyze the legal framework for the prevention and control of these types of pollution in Mexico. [ABSTRACT FROM AUTHOR]

This paper analyzes self-solidarity as a position in the face of extreme poverty and shows the articulated complex of homelessness and the difficulty in overcoming it. Raymond's life story, as a case study in northern Mexico, unravels the link between migration, masculinity(ies) and social exclusion and its relationship with the street situation of deported ex-migrant men, collective helpless by social policy. Raymond's life trajectory exposes violence, contexts of vulnerability and resignifications, highlighting an example of descending social mobility. It is concluded that self-solidarity, as an autonomous position against homelessness, is developed as a practical tool in self-care, an element of resilience and a way to understand the experiential context and direct support demands.

This paper analyzes the experiences of vulnerability and the development of resilience in trans women and gay men from Central America who transited through Mexico to the United States between 2017 and 2020. Based on interviews conducted in a shelter for lgbt+ migrants in Tijuana, it is shown that vulnerability is expressed in acts of violence and discrimination by authorities, criminal organizations, and other migrants, in response to the sexual orientation and gender identity of trans women and gay men. In contrast, resilience developed thanks to the support provided by networks of the lgbt+ community itself in the form of chosen families and civil society spaces. From this, it is observed that even within vulnerability, mobility enables the development of resilience through new ways of living gender and sexuality. [ABSTRACT FROM AUTHOR]

The paper investigates the impact of the international trade on employment of the northern border states of Mexico and its integration with the economy of the United States during 2007-2020. In order to analyze the effect of commercial penetration on the evolution of employment in the region, a dynamic panel model is used to estimate the effect of exports and imports. The results indicate that at the level of total exports there is no clear correlation of the penetration of exports on employment in the region. In contrast, the penetration of manufacturing exports and imports showed a positive and statistically significant effect on manufacturing employment in the northern border region of Mexico. The coefficient of average manufacturing wages showed an inverse coefficient suggesting that the employment dynamics are limiting the growth of wage income. [ABSTRACT FROM AUTHOR]

This paper questions the actions originated from Corporate Social Responsibility, implemented by companies carrying the ESR Badge during the National Day of Healthy Distance by Covid-19 in Mexico. The objective is to contribute to the theoretical discussion and studies developed around CSR based on its analysis in the light of the dominant paradigm and the emerging paradigm, that in a context of maximum crisis allow to evaluate the exercise of the CSR through the actions carried out to manage the relations with the workers. The research was based on qualitative methodology, through an instrumental case study. It is concluded that the exercise of CSR during the National Day of Healthy Distance in the company studied responds to the interest of the organization to generate a positive impact on its workers through social responsibility initiatives.
