The objective of this study was to examine the factors influencing user satisfaction with digital payment methods in emerging contexts. Data were collected through 258 surveys conducted with Mexican users and were analyzed using multiple linear regression. The results indicate that security and privacy, customer service, convenient payment, and information quality are factors that determine user satisfaction with online payment methods. This research contributes to the analysis of user experiences of online payment services for the acquisition of products and services over the internet.

Experiencing Political Advertising Through Social Media Logic: A Qualitative Inquiry

<span style="font-size: 10.0pt; mso-bidi-font-size: 11.0pt; line-height: 107%; font-family: 'Calibri',sans-serif; mso-fareast-font-family: Calibri; mso-bidi-font-family: 'Times New Roman'; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;" lang="EN-US">The allocation of political advertising in social media is rising in Western campaigns. Yet audiences, unlike those of television advertising, are no longer isolated and passive consumers of linear discourses from politicians; users can now interact, share, and merge political advertising with other messages. Literature has dealt with the effects of such affordances separately, yet not in an integrative, holistic way that makes it possible to observe how they interact with each other. Hence, this article explores qualitatively how users experience, engage with, and make sense of political advertising in social media, and how its affordances mediate the attitudes, responses, and meanings users bring to political advertising and its sponsors. Under the lenses of the theory of social media logic, which points out the properties of social media—popularity, programmability, datafication, and connectivity—that structure users’ experiences, we conducted six focus group sessions with Mexican users (<em>n</em> = 34) during the 2021 federal campaigns. Findings show the fuzziness of digital advertising for users, which blurs with other formats like infographics or memes, the crucial role of individual linkages for advertising attention and attitude formation, a mismatch between the platform’s political feed and citizens’ information needs, and the tactics users perform to tame or avoid political content, disengaging them from campaigns.</span>

Entrenar al algoritmo: gobernanza, agencia y literacidad en el uso de YouTube

This study addresses the experiences of young Mexican users with YouTube’s recommendation algorithms. It seeks to determine if they are subordinated to algorithmic governance or if, on the contrary, they are capable of developing some tactics to resist algorithmic power through their agency. It uses a qualitative methodology based on focus groups and shows that users are not entirely subordinated to the platforms. Their possibilities of agency vary depending on the different technological appropriations of the platform, the intuitive theories about the ways in which these operate, the ability to dodge algorithmic distortions, and the resources to evaluate the quality of the information offered. As a result, the study identifies the specific skills that constitute algorithmic literacy.

Effectiveness of a chronic disease self-management program in Mexico: A randomized controlled study

Objective: To assess the effectiveness of a Spanish-language version of the Stanford Chronic Disease Self-management Program among adults who received medical care in community health centers in Mexico.Methods: This was a prospective, randomized study with Mexican users of community health centers in Tampico, Mexico, conducted between September 2015 and July 2016. A total of 120 adults aged 18 years or older were randomly assigned to intervention (n = 62) and control (n = 58) groups. Data were collected at baseline and at 3 and 6 months post intervention using a structured questionnaire. A repeated measures ANOVA was used for data analysis.Results: Statistically significant differences were found in intervention participants at 3 and 6 months post intervention compared to baseline and the control group for self-management behaviors, including: social activity limitation, quality of life perception, depression, stress, physical activity, communication with physicians, adherence to physician visits, and self-management behaviors.Conclusions: Chronic disease self-management programs (CDSMP) with Mexican adults in community settings are effective in improving their health and self-management behaviors. Further research is needed to assess CDSMP in Mexico and Latin America using objective measurements and examining health outcomes and self-management maintenance over longer periods of time.

Escrutinio de depresión y ansiedad en twitter a través de un programa de análisis de palabras

IntroductionTwitter is the second most used social network in the country, with about 10.2 million users. It is possible that mood may be reflected in texts posted by users of Twitter. A group of specialists designed a software that attempted to analyze the statements posted on Twitter and to detect various components of personality. The study focused on ascertaining whether it is possible to use these postings as elements for depression or anxiety, and comparing the consistency between the interpretation of software testing and in vivo using a standardized diagnostic inventory. MethodsA correlational comparative study with convenience sampling of 18 to 24 year-old medical students from the Autonomous Metropolitan University who have active Twitter accounts by applying, in person, the Depression and Beck Anxiety Inventories. Once applied, it was used in the accounts of Twitter Software Analyze Words for the analysis of their postings. The results were downloaded and analyzed using the SPSS program. ResultsThe minimum score for the Beck Anxiety Inventory was 0, the maximum was 29, and the mean was 9.37. For depression, the minimum was 0, the maximum 20, and the mean 4.94. For the tests performed by the Words Analyze software for anxiety, the lowest result was 19, a maximum of 99, and a mean of 54.58. A minimum of 35, a maximum of 66, and a mean of 51.89 was obtained for depression. A value of Pearson correlation of —.197 was obtained for anxiety in the analysis with the Beck inventory and Analyze Words software. Similarly, Pearson R value of .047 was obtained in the same tests for depression. ConclusionsThere is no agreement between the results, and it is considered that the software is designed for the U.S. population and postings by Mexican users do not project their emotions as it does for Americans and would not have the necessary characteristics to determine mood. In conclusion this study shows that Twitter is not a diagnosis indicator of probable depressive or anxiety disorders.

Metabolic effects of the contraceptive skin patch and subdermal contraceptive implant in Mexican women: a prospective study.

BackgroundThe contraceptive skin patch (CSP) accepted by the U.S. FDA in 2001 includes ethinylestradiol and norelgestromine, whereas the subdermal contraceptive implant (SCI) has etonogestrel and is also approved by the FDA. In Mexico, both are now widely used for contraception but their effects on Mexican population are unknown. The objective of the study was to evaluate if these treatments induce metabolic changes in a sample of indigenous and mestizo Mexican women.MethodsAn observational, prospective, longitudinal, non-randomized study of women between 18 and 35 years of age assigned to CSP or SCI. We performed several laboratory tests: clinical chemistry, lipid profile, and liver and thyroid function tests. Also, serum levels of insulin, C-peptide, IGF-1, leptin, adiponectin, and C reactive protein were assayed.ResultsSixty-two women were enrolled, 25 used CSP (0 indigenous; 25 mestizos) and 37 used SCI (18 indigenous; 19 mestizos). Clinical symptoms were relatively more frequent in the SCI group. Thirty-four contraceptive users gained weight without other clinical significant changes. After 4 months of treatment, significant changes were found in some biochemical parameters in both treatment groups. Most were clinically irrelevant. Interestingly, the percentage of users with an abnormal atherogenic index diminished from 75% to 41.6% after follow-up.ConclusionsThe CSP slightly modified the metabolic variables. Most changes were nonsignificant, whereas for SCI users changes were more evident and perhaps beneficial. Results of this attempt to evaluate the effects of contraceptives in mestizo and native-American populations show that clinical symptoms are frequent in Mexican users of CSP and SCI. Although these medications may affect some metabolic variables, these changes seem clinically irrelevant. Induction of abnormalities in other physiological pathways cannot be ruled out.

An examination of the information quality perceptions of Mexican internet users

Mexico was a relatively early adopter of the internet, and although broadband access has been limited in some parts of the country, the government has aggressively sought to provide internet access to users throughout the country. This study reports the results of a study of perceptions of information quality among Mexican users of the internet. Results are reported from a survey of internet users at two Mexican universities in which perceptions of 15 dimensions of information quality are assessed. The nine dimensions of believability, accuracy, objectivity, reputation, value-added, ease of understanding, representational consistency, concise representation, and access security have higher ratings for traditional text sources of information than for internet sources of information. In contrast, the dimensions of timeliness and accessibility have higher ratings for internet sources than for traditional text sources of information.

Blood copper levels in Mexican users of the T380A IUD

Objective Copper T380A is one of the most commonly prescribed intrauterine devices (IUDs). However, there are few reports of its systemic health effects. This study evaluates the association between the use of T380A IUD and blood Cu levels in a group of Mexican users. Methods Eighty-six T380A users and eight nonusers were recruited. Blood Cu levels were measured using an atomic absorption spectrophotometic technique. Results In IUD users, mean blood Cu level was significantly higher than in nonusers, 216.63 vs. 107.47 μg/dL (p≤.001), and above the normal blood Cu level range of 80–160 μg/dL. No significant difference in blood Cu levels was observed by age or length of time of IUD use. Conclusions The observed higher blood Cu levels among T380A user stands out in sharp contrast to previous reports of other types of Cu IUDs. Further research should evaluate if the observed levels are associated to toxic effects with the general population or special groups.
