Recent technological advances have significantly impacted news media in the way they provide news to the public, evolving into a digital environment. Therefore, digital media today focuses on generating readers' loyalty to their news websites. In this sense, a multiple linear regression analysis was carried out on a sample of 344 surveys of adult residents in the cities of Mexico and Monterrey. The results show that factors such as familiarity, satisfaction and reputation are positively related to the loyalty of news website users. However, they also show that the importance of the impact of these factors is different when the analysis is carried out in a stratified manner, such as residence, gender or education, which allows us to conclude that digital media can guide their loyalty efforts depending on the profile of their readers and the market they seek to target. To illustrate focusing on stratification by place of residence, the most significant factors for the Mexico City group corresponded to familiarity and satisfaction, wile for the Monterrey group the most significant factors were reputation and familiarity in that order. Results with this type of differences between groups were also obtained when comparing by gender and schooling. It is recommended for future research on the subject, to include other cities within the country, with the purpose of contrasting these paper's findings. [ABSTRACT FROM AUTHOR]

The pandemic generated containment and mitigation policies, as well as distancing and confinement strategies that limited the supply of water resources to social sectors. Residential areas- The offer is maintained, but with an increase in rates. Marginalized areas were subsidized and exempted from paying for an increasingly intermittent supply. The anti-COVID-19 policies guided water policies in two ways: The first consisted of disseminating anti-COVID-19 policies in water management agencies. Another second consisted of the autonomy of the institutions and their disassociation or agreement with the antiCOVID-19 policies. In this way, the literature from 2020 to 2023 around anti-COVID-19 policies in their water dimensions, registers problems of scarcity, famine and unsanitary conditions. Scarcity had already been observed in marginalized sectors, famine in residential neighborhoods, but unsanitary conditions were appreciated in migrant communities. In fact, the type of exposure to occupational hazards determined the health status of the migrants. The water problems were recorded in the circulation press to highlight the asymmetries of the anti-COVID-19 policies in the public and private sectors, as well as in the political and social actors. The objective of the study was to reveal the network structure of relationships between nodes and edges related to press releases on water issues. A documentary, cross-sectional and retrospective study was carried out with national circulation newspapers: El País, El Reforma, La Jornada and El Universal, considering the water problems of scarcity, unsanitary conditions and famine. The results show a structure of nodes where the water problems were initiated by La Jornada and ended by El Reforma. Both findings are relevant considering the ideology of the newspaper. La Jornada, a newspaper identified with the political ideology of the left, began the diffusion of water problems in a city administered by a government of the same ideology. El Reforma, a newspaper designated by the executive as a spokesperson for the opposition ideology, culminates the network of notes on water problems. In other words, regardless of the type of political ideology attributed to newspapers, the problems of scarcity, unsanitary conditions and famine are spread.In relation to the state of the art where it is shown that ideology does not influence the establishment of the agenda, the present work corroborates and recommends expanding the study to other entities administered by the opposition such as the cities of Guadalajara and Monterrey.

In the three major urban agglomerations in Mexico (Mexico City, Monterrey, and Guadalajara), a significant change to anthropogenic sources of air pollution happened in March–May 2020, when policies implemented to stop the spread of the COVID-19 virus in Mexico caused the reduction of some anthropogenic sources of air pollution. We study the effect of these significant changes to air pollution sources using satellite-retrieved aerosol optical depth (AOD) and particulate matter (PM10 and PM2.5) concentrations from ground stations. The Chow test was applied to study trend changes in PM concentrations from 1 January to 30 May 2020. The Mann–Whitney non-parametric test was then used to compare average PM concentrations in April and May pre-lockdown, during lockdown in 2020, and post-lockdown in 2021. The assessment was further performed by evaluating the exceedance of national air quality standard maxima. The trend analysis showed that PM10 concentrations were reduced during lockdown in Mexico City and Monterrey, whereas no change was found for PM10 in Guadalajara and PM2.5 in the three cities. Further analysis showed that in Mexico City and Guadalajara, average PM10 and PM2.5 concentrations decreased by 12% in April and May 2020. However, in Monterrey, average PM10 and PM2.5 concentrations increased by 2.76% and 11.07%, respectively, in April 2021 due to a severe drought that caused dry soils and dust around the city. The results of this research can be used to implement policies for reducing anthropogenic sources to improve the air quality in urban areas. [ABSTRACT FROM AUTHOR]
