Several studies have examined the relationship between monetary policy and the stock market. However, few have assessed the impact of fiscal management on this market. This paper examines the extent to which fiscal policy affects a firm's stock market capitalization using the Panel Vector Autoregressive (PVAR) methodology. The study finds that the stock market capitalization in the CPI fully reflects the available information on the movements of variables related to monetary policy. However, total public indebtedness exerts a significant lagged effect on the stock market capitalization of Mexican firms. This finding indicates that the CPI does not fully reflect the available information on the movements of fiscal policy variables. A comprehensive analysis of fiscal policy measures can enhance stock market performance for investors and financial analysts. [ABSTRACT FROM AUTHOR]

Introduction: The notion of objectivity is the cornerstone of the liberal model of journalism. Following that scheme, one of the aims of news stories is to foster citizens’ understanding of the world they live in, but this can only be achieved through journalists’ vision. In that sense, the aim of this article is to analyze the level of interpretation and contextualization that Mexican journalists deliver when they report on organized crime. Methodology: In doing so, this paper draws on 24 in-depth interviews with news workers who cover this beat across the country. Results and discussion: The findings suggest that journalists do interpret and contextualize the information. This is because they are interested in helping their audiences to better understand this highly complex phenomenon. Although most of the informants said that they separate facts from opinion, they constantly interpret the information by relying upon their amplified subjectivity; which represents the main contribution of this inquiry. Conclusions: The main conclusions suggest that criminals’ pressure constrains reporters’ freedom to interpret the information they publish. Therefore, despite journalists’ efforts, the average Mexican news consumer cannot fully understand the organized crime phenomenon. [ABSTRACT FROM AUTHOR]

Some Latin American countries have introduced presidential recall in the last three decades. This exceptional and spontaneous mechanism by which somebody can remove a servant elected through a popular vote from office before the end of his term aims to broaden participation, empower citizens, and improve the responsibility and accountability of servants. However, the recall faces the challenge of being an instrument serving interests outside of its normative ideal. What are the consequences of holding a recall referendum? Under what conditions can the recall yield better results and be more effective? This paper answers these questions by comparing the presidential recall held in Venezuela, Bolivia, and Mexico. The evidence suggests that the mechanism can have substantial advantages and fulfill its objective when its holding is justified, there is no intervention from relevant political actors, and the institutional design does not hinder or discourage participation.

This paper analyzes the importance of the melting of the Arctic ice for Mexico. The research examines the impacts of this process, the Mexican government’s environmental policies, citizen’s perception and the media’s approach to climate change and the melting of the Arctic ice. To obtain the results, an exploratory analysis was carried out, from which it was concluded that, despite the importance of the Arctic melting in the current climate crisis affecting all countries, and specifically Mexico, within the political agendas of the nation, the citizenry and the mass media, both climate change and the Arctic melting are secondary issues.

Since its appearance in 2020, Brazil and Mexico have been among the most affected countries in the world by covid-19. Their respective presidents, Jair Bolsonaro and Andrés Manuel López Obrador (known as AMLO), have played a leading role in specific policies during the pandemic. Their choices were both singular and counter- intuitive. On the health front, AMLO initially underplayed the seriousness of the situation, and the Brazilian president, Bolsonaro, defended a frankly negationist attitude, with a dramatic balance sheet, without his popularity being seriously affected. On the economic front, they have chosen policies that contradict not only each other but also their own supposed ideological stances. Bolsonaro, who is ranked on the far right, has implemented an emergency transfer program on a scale comparable to those of developed countries and the most massive the country has ever seen. Conversely, AMLO, considered a progressist, provided just a minimum policy package, maintaining his previous electoral program. By adopting a comparative approach and mobilizing a unique and diversified set of data, the objective of this paper is to explore these apparent contradictions. After having established the precise diagnosis of the policies implemented to deal with the crisis and the economic and health situation in the two countries during the 2020-2022 period, we propose an original interpretation grid of the central role played by the two presidents.

The changes in Mexican economic policy within neoliberalism implied serious transformations in labor relations and forms of labor organization. Based on this, the aim of this paper is to analyze the implications that practices such as protection contracts and subcontracting had on the organization of workers, and the subsequent labor reforms, still limited, which make possible new schemes of dynamization within unions, through new demands framed within the rights of labor citizenship. Methodologically, a brief description is made of the main changes in the Mexican economy and the labor context since the last decade of the last century and the first two of the present Century. This is linked to the conceptual elements of the centrality of labor and labor citizenship. It concludes by pointing out that labor reforms make possible new scenarios of opportunity for Mexican trade unionism. [ABSTRACT FROM AUTHOR]

This paper examines the clashes among leftist Mexican intellectuals at the beginning of the 1970s as a consequence of the Cuban Revolution. The correspondence of Laurette Séjourné, an archeologist of Italian origin based in Mexico, provides a source for identifying the tensions generated between those who had maintained an unconditional loyalty toward die Cuban regime and those who had distanced themselves following its Sovietization. This confrontation shows that the New Left was not an ideologically homogenous group and leads to questioning the use of this category. [ABSTRACT FROM AUTHOR]

Commonly known as “sea spiders”, pycnogonids are a group of exclusively marine arthropods. In Mexico, 62 species of Pycnogonida have been reported from almost all the coastal Mexican states. This data is the result mostly of investigations carried out by foreigners and recent studies of sporadic collections focused on meiobenthos fauna. The aim of this paper is to disclose the samples of pycnogonids contained in the National Collection of Mites (CNAC), which was part of PhD. Anita Hoffmann’s collection and which was collected from two different locations in the Mexican Pacific by PhD. Federico Bonet in the 1940s. Three species were identified from the total of 20 specimens: Achelia sawayai (Montagu, 1808), Anoplodactylus californicus Hall, 1912, and Endeis cf. spinosa Marcus, 1940. For the first species, a record is added to the already known wide distribution. E. cf. spinosa was recorded for the first time in the Mexican Pacific, and for A. sawayai, records of its distribution in the country are expanded. Furthermore, the importance of biological collections as material sites for the recognition of biodiversity is highlighted. [ABSTRACT FROM AUTHOR]

This paper used a new source of information (ESRU-EMOVI NL) to estimate, for the first time, the lower limit of unequal opportunities in a federal state in Mexico. Using the former criterion concerning unequal opportunities, a lower threshold indicated 35% inequality in economic resources in the state. As at the national level, the main contributors to unequal opportunities in the state are unequal economic resources by origin and parental education. However, in contrast to what has been observed, for the country as a whole, inequalities associated with people's skin tone account for 5% of observed unequal opportunities. [ABSTRACT FROM AUTHOR]

Research on pre service teachers' thinking about reading is relevant due to the reading comprehension problems in our country. Therefore, the aim of this paper is to describe the implicit theories of reading comprehension of a group of students enrolled in a BA program in English Language Teaching. The scale of implicit theories of reading comprehension was used with a quantitative, descriptive approach. Three implicit theories were identified: critical receptive, sourcing, and literary. most participants hold the critical receptive implicit theory, which focuses on ideological critique and inferring implicit messages. A smaller group holds the rhetorical implicit theory, which focuses on evaluating and contrasting sources and is highly functional for college reading. The literary implicit theory is held by a small minority. These findings suggest that pre-service teachers in the target context need better training in rhetorical and literary reading.

The challenges faced by teachers during the confinement caused by Covid-19 were more severe for those who look after students with special needs or learning barriers, particularly in a context marked by the scarcity of specialized technological tools and an incipient development of digital skills among both teachers and students. The paper analyzes the conditions in which teachers who work in basic and upper secondary education in Mexico carried out their jobs from April 2020 - December 2021. The analysis is based upon a structural attributive research of explanatory scope that retrieved information through a survey. 140 teachers participated in the process; their responses were statistically analyzed and mapped out using the Geographic Information System and the ArcGIS program, in order to highlight regional differences and shortcomings. The results presented focus on two axes of the Common Framework for Digital Teaching Competence (Content Creation and Security) and show the persistence of socio-educational gaps. Those who express that to have developed these competences are teachers from urban areas, particularly those who have less years of service, higher academic degrees, and are in the seek of job stability. This leads to the conclusion that there is a need to strengthen differentiated training processes that respond to the specific needs of educational contexts. [ABSTRACT FROM AUTHOR]

The purpose of this article is to argue that Mexico's involvement in the Universal Exhibitions and World Fairs of the nineteenth century can be considered as the immediate background of what would be called cultural diplomacy in the twentieth century. The evidence found is that Mexico started a tradition that will remain nowadays. The influence of history, as well as the richness and diversity of its artistic and cultural production were their "letters of credence" that allows the country to be appreciated and recognized internationally. Based on testimonies from those who witnessed and attend the exhibitions, as well as official documents and papers of that period, the features of these exhibitions were exposed. To this end, this paper analyzes Mexico's involvement in three of the most important exhibitions of nineteenth century: 1851, 1889 and 1900. This selection allows to compare different contexts and at the same time contributes to observe Mexican political narrative evolution. This article aims to show that the Universal Exhibitions were an opportunity for Mexico to be known and to promote an idea of a country that was aligned with the canons of that century: progress, civility and peace.

This paper examines the factors of stage of establishment, region of destination, country of origin and union as determinants of the annual integrated wage of unionized workers through the analysis of the collective bargaining agreements of the year 2019 for 20 automotive assembly companies. Kruskal Wallis analysis and Dunn-Bonferroni tests are used to determine whether wage differences existed. The findings show that from the third stage of establishment wages decreased. The central and northern regions displayed high wages, but western and central-northern regions displayed low wages. In the case of companies of European origin, they displayed high wages, while Asian companies displayed low wages; in unions of FESEBS higher wages and FNSI low wages. [ABSTRACT FROM AUTHOR]

The purpose of this paper is to show the perspectives of companies, school tutors and graduates on the Mexican Dual Training Model (MMFD) in the CBTIS of the State of Hidalgo. For this, we followed a mixed methodology using semi-structured interviews and a questionnaire to find out the perception of the MMFD. In this way, we identified an articulation between education and employment and that the MMFD generates and promotes new dynamics. Likewise, we observed effects such as the development of competencies in graduates and internships in companies and the reach in employability by graduates. We set out conclusions and recommendations for its application in Mexico. [ABSTRACT FROM AUTHOR]

This paper, based on qualitative interviews realized between 2014 and 2022 with 36 Central American migrant women captured by drug cartels when they transited through Mexico, aims to examine the different repertories used by criminal organizations to capture, exploit, and subject the victims to a condition of sexual slavery. It is concluded that criminal groups have developed four different repertories, which aim to tame the body and mind of the slaves to achieve total submission: kidnapping, deception, recruitment in the country of origin and extortion. Inside these organizations the roles of victim and perpetrator are interchangeable, and enslaved women are not always passive victims, but some rescue themselves using both astuteness and brute force.

The study of sediment transport is important to understand how erosive processes operate on the earth's surface and to try to manage natural resources in an optimal way. This paper studies the mechanisms of surface transport of sediments in two high mountain headwaters that have similar topographic and lithological characteristics with an ecosystem of high ecological value characterized by the alpine grassland. These headwaters are distinguished in that one is in a natural state, located in the Altzomoni gorge, and the other has implemented management practices consisting of the construction of infiltration trenches and afforestation, in the Amalacaxco gorge. Both headwaters are located within the Iztaccihuatl-Popocatepetl Zoquiapan National Park (central Mexico). In the study, the luminescence signals were analyzed with the optically stimulated luminescence (LOE) technique to understand the degree of erosion that exists. The luminescence of the two deposits that make up the surface of the two headwaters was estimated and the LOE signals were analyzed in samples taken on the surface in longitudinal profiles along the slope in three different periods of one year, this to consider the variability associated with seasonal changes. The results indicate that most of the materials that are mobilized downhill come from the surface deposit. However, during the months that concentrate the greatest rainfall and solar radiation, the subsurface materials, more than 80 cm deep, but only in the Amalacaxco gorge, are mobilized punctually. This indicates that erosion is greater in the gorge where the management techniques were implemented, which contrasts with what is observed in the gorge in its natural state. It is concluded that the management techniques applied modify the surface dynamics and favor the incisive processes of the alpine grassland. The use of the method used is appropriate to study erosive processes in high mountain areas. [ABSTRACT FROM AUTHOR]

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.

This paper examines in-depth the root causes and consequences of Mexican forced displacement from a decolonial feminist perspective, emphasizing the intersections between the body and territory. The absence of quantitative and qualitative data on internal forced displacement in Mexico erases people and communities from the territory, making them invisible along the migratory routes and making them disappear on the map of contemporary geographies of terror. In this article, we focus on the embodied experiences of women, drawing upon extensive multi-sited binational research along the Mexico-US border. Their testimonies allow an understanding of forced displacement beyond passive and re-victimizing narratives. [ABSTRACT FROM AUTHOR]

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 shows the state of the social capital between 2004 and 2014 in front of the implementation of the Mexican policy of attention to poverty. The investigation contemplates the beginning of the OPPORTUNIDAES program, and its passage to the PROSPERA program. The first study was conducted in a municipality in the state of Guerrero, and the second in the state of Oaxaca. The work made use of semi-structured interviews, face-to-face and with a mixed questionnaire, these were complemented with the observation technique to obtain a contextualized understanding of the situation at different explanatory levels. The results show that the policy of attention to poverty has a negative effect on the development of social capital. It was observed that the targeting method employed by these poverty attention programs creates two networks of social relationships, beneficiaries and non-beneficiaries; from the perspective of social capital, this influences the development of cooperation, solidarity, trust, reciprocity and social norms; that is, the fragmentation of social ties in a community has an impact on local development, and this does not counteract poverty.

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.

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.

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]

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.

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]

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 Mexican economy has moved to an outward growth model that has resulted in a spatial restructuring of manufacturing activities. This transformation has allowed the incorporation of the regional economy, in which the local and the global interact to promote the expansion and well-being of the localities. The general objective of this paper is to describe the performance of manufacturing in Mexico through its regional composition based on total factor productivity (TFP) in the period 1993-2018. The applied methodology is the Solow Residual model with a Cobb-Douglas production function with constant marginal returns to analyze the sources of growth. The results show regional asymmetries in TFP growth, on the one hand, the northern border and central-north regions register significant growth and, on the other, the central and southern regions have lagged due to inefficient performance that has resulted in a limited productivity performance of Mexican manufactures.

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]

The article reviews the main projects supported by Conacyt during the government of Luis Echeverria Álvarez (1970-196), both with its own resources and with those of international cooperation. On the other hand, it also reviews the scientific articles published during the same period that were considered relevant in the indexes of the site Web of Science. Today, those indexes are taken into account as a relevant indicator of scientific work in Mexico. Finally the information about the projects and the articles are crossed to test the hypothesis of our research: the institutionalization process of the science system in Mexico started in 1970 allowed us to organize, support and promote scientific research in the country. allowing the rise of relevant papers published. The objective is to show the impact that the new institution had on the dynamics of scientific work at national and international level. [ABSTRACT FROM AUTHOR]

During the New Spain viceroyalty, cultivation in irrigated orchards was a common practice in the semi-arid region of the west of the current state of Hidalgo, Mexico, where the ethnic group known as hñähñü settled. In this paper we focus on the analysis of the areas bathed by rivers and springs in the towns of Ixmiquilpan, Tecozautla and San José Atlán. Our objective is, in the first place, to expose the process of arrival of new plants as a result of the conquest that the Indian peoples adapted to their agriculture; second, to describe the variety of products obtained in orchards between the 16th and 18th centuries, and, finally, to show the relevance of the uses of water as a factor that favored cultivation in this agroecosystem. The sources that fed the investigation are wills, letters of rent or sale, judicial files and general descriptions made in the territory of New Spain. We conclude that hunting and gathering were not the only economic activities of the indigenous population in the studied region. [ABSTRACT FROM AUTHOR]

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.

Since his arrival to the presidency of Mexico in 2018, López Obrador has established a communication strategy focused on his daily press conferences, called mañaneras, through which he tries to establish the informative agenda of the country. It is common for the president to use a discursive rhetoric tending to polarization, for which he makes use of cues or labels that offer a context to understand the issues on which he is pronounced. The paper seeks to analyze the use of labels or cues by the president in his discourse, for which a quantitative content analysis was carried out on a sample of his interventions (N = 867) during a year in the mañaneras. The findings made it possible to detect two discursive schemes from the convergence of different cues: one that tends to present an Us visualized in a new government scheme, linked to positive aspects such as engagement or the fight against corruption, compared to an Others that presents the previous government, linked to negative aspects such as corruption.

The Mexican automotive sector--integrated into the regional value chain of North America, led by the United States--is characterized by performing mainly manufacturing tasks, which limits its value-added contribution. However, this does not imply that the environmental impact resulting from these tasks is proportional to the value it generates. The paper aims to analyze this dual dimension of the Mexican automotive sector, by describing both its productive structure and its environmental impact related to its foreign trade flows. The results reveal uneven participation in the regional value chain depending on whether Mexican value-added exports are considered in monetary or emission terms, which exhibits a greater contribution in terms of emissions than in value compared to the United States.
