Has the past decade of sustained economic growth and political transformations reversed Latin America's historical failure to secure market and social incorporation? To address this question this article draws on the experiences of Bolivia, Brazil, Chile, Peru and Uruguay by distinguishing between short-term outcomes - which may depend on benign international conditions - and policy changes, which are more important for long-term performance. It highlights the overall success of both Brazil and Uruguay and shows that the other countries have made more progress in terms of social than market incorporation. [ABSTRACT FROM AUTHOR]

Purpose: This study aims to identify the strategic leadership and change management used to obtain the Association to Advance Collegiate Schools of Business (AACSB) accreditations as well as the research development on AACSB in the past decade. Design/methodology/approach: This study used a systematic literature review following Petticrew and Roberts' study. The articles were limited to empirical studies published from 2013 to 2022, taken from the Dimensions AI database. Findings: The findings suggested that two leadership styles were used to obtain AACSB accreditation: dominance-oriented transformational and financial leadership, alongside three traits of academic leaders: commitment, engagement and encouragement. Additionally, three change management models/processes were found in the articles: teaching evaluation framework, temporary isomorphism and authenticity. Finally, they discovered that the object of the studies on AACSB accreditation had been narrowed down from the organizational level to smaller objects consisting of schools' identity, teaching, learning and business schools' key players. Research limitations/implications: As this study only used Dimensions AI, potential articles related to the topic outside the database could not be obtained. Thus, it limits the scope of the findings of this paper. Practical implications: This study informs academic leaders in business schools about the role of strategic leadership and change management in obtaining AACSB accreditation. Originality/value: Through a systematic scoping review, this study presented a decade of research development on AACSB in addition to the strategic leadership and change management needed to obtain it.

This paper analyzes the relationship between the financial instability generated by shortterm capital flows in the absence of control mechanisms and the restrictions facing the implementation of counter-cyclical fiscal policies in the inflation-targeting regime, using as a springboard the recent financial crises in, specifically, Brazil, Chile, Colombia, Mexico, and Peru, showing how an increase in the issuance of public bonds to, via interventions in the exchange rate market, sterilize the effects of short-term capital flows on the monetary base is a source of endogenous instability, because this mechanism entails risks for the exchange rate and interest rate.

This study considers the role that public service announcements (PSAs) play in addressing violence against women (VAW) in Latin America. Using content analysis, the study examines 407 PSAs about VAW from 20 Latin American countries. The results show that 62.3% of the PSAs encourage bystanders to denounce violence while portraying women as victims in 48.8% of the PSAs. However, 71.7% of PSAs did not include a helpline or how to report the crime, only 11.8% of the PSAs have non-narrative, or factual information, about VAW, and just 6.4% engage in compelling narrative messaging or storytelling.

Objective: Our study analyzes the cost-effectiveness of the COVID-19 vaccination campaigns in Argentina, Brazil, Chile, Colombia, Costa Rica, Mexico, and Peru. Methods: Using a previously published SVEIR model, we analyzed the impact of a vaccination campaign (2021) from a national healthcare perspective. The primary outcomes were quality adjusted life years (QALYs) lost and total costs. Other outcomes included COVID-19 cases, hospitalizations, deaths, and life years. We applied a discount rate of 3% for health outcomes. We modeled a realistic vaccination campaign in each country (the realistic country-specific campaign). Additionally, we assessed a standard campaign (similar, "typical" for all countries), and an optimized campaign (similar in all countries with higher but plausible population coverage). One-way deterministic sensitivity analyses were performed. Findings: Vaccination was health improving as well as cost-saving in almost all countries and scenarios. Our analysis shows that vaccination in this group of countries prevented 573,141 deaths (508,826 standard; 685,442 optimized) and gained 5.07 million QALYs (4.53 standard; 6.03 optimized). Despite the incremental costs of vaccination campaigns, they had a total net cost saving to the health system of US$16.29 billion (US$16.47 standard; US$18.58 optimized). The realistic (base case) vaccination campaign in Chile was the only scenario, which was not cost saving, but it was still highly cost-effective with an ICER of US$22 per QALY gained. Main findings were robust in the sensitivity analyses. Interpretation: The COVID-19 vaccination campaign in seven Latin American and Caribbean countries -that comprise nearly 80% of the region- was beneficial for population health and was also cost-saving or highly cost-effective.

Purpose: This paper aims to present an approach to achieve accessible and inclusive Virtual Education for all, but especially intended for students with disabilities. This work proposes main steps to take into consideration for stakeholders involved in the educational process related to an inclusive e-Learning. Design/methodology/approach: The paper pays particular regard to accessibility in Virtual Education. This work is based on the activities prepared from years 2012 to 2015 within the initiative called ESVI-AL. This initiative was carried out in conjunction with Latin American and European Universities; for this paper, experiences and best practices from the initiative were used to prepare the proposed approach. Findings: The aim of ESVI-AL initiative was to offer products that can help in the development of an accessible and inclusive e-Learning education. Among the main results were reports, case studies, practical guidelines, training courses and software to install virtual campuses with accessibility features. Social implications: Nowadays, few countries have laws promoting and enforcing accessibility for e-Education and e-Society. This work aims to sensitize educators from different countries and raise awareness on the importance of working together toward an inclusive society based on accessible e-Learning. Originality/value: Based on a literature review and ESVI-AL initiative results, a descriptive overview was prepared as a starting point for the four identified main actors of an educational project, namely, educators, technical staff, quality auditors and students, with special emphasis on students with disabilities.

This paper aims to evaluate and discuss the digital competence of academics at universities, to identify challenges and define recommendations for policy. This study was conducted through collaboration between the Joint Research Centre (JRC) of the European Commission and Metared of the Universia Foundation, surveying 30,407 participants who present the perceptions of their own digital competence levels. These self-reflections took place in universities in seven countries, namely Argentina, Brazil, Colombia, Chile, Peru, Mexico and Portugal, and used the Check-In tool, which consists of 22 questions based on the European Framework for the Digital Competence of Educators--or 'DigCompEdu' framework. A descriptive statistical analysis was performed, followed by a qualitative evaluation. Almost 70% of the academics have an average intermediate level of competence when the data is aggregated, with results varying in each DigCompEdu area according to the specific question asked. There is no significant difference between young and senior academics, as well as between men and women. The results present a discussion of whether the age and gender of educators and their work environment have an impact on their digital competence level, and at the same time highlights the areas in which educators perceive themselves to be most and least competent. It shows how the amount of institutional support that is offered affects the academics' perceptions of their level of digital competence. On the basis of the results, recommendations are presented for higher-education institutions, with the aim of supporting the professional development of their academics.

Latin American countries have evolved over the years. Still, after years of military reign, socioeconomicinstability, and civil wars, the region has been known for its anti-hegemonic economic growth (educationalpolicies) strategies. Central and South America's educational system has long been under investigation by researchers both theoretically and empirically. The transition of its education system through the introduction of centralized, liberalized, and populist ideology has sparked many researchers' interest. This paper aims to understand and compare 14 Latin American countries' education orientation. The study uses a matrix table to visualize the qualitative finding.

In the COVID-19 pandemic, patients who are older and residents of long-term care facilities (LTCF) are at greatest risk of worse clinical outcomes. We reviewed discharge criteria for hospitalised COVID-19 patients from 10 countries with the highest incidence of COVID-19 cases as of 26 July 2020. Five countries (Brazil, Mexico, Peru, Chile and Iran) had no discharge criteria; the remaining five (USA, India, Russia, South Africa and the UK) had discharge guidelines with large inter-country variability. India and Russia recommend discharge for a clinically recovered patient with two negative reverse transcription polymerase chain reaction (RT-PCR) tests 24 h apart; the USA offers either a symptom based strategy—clinical recovery and 10 days after symptom onset, or the same test-based strategy. The UK suggests that patients can be discharged when patients have clinically recovered; South Africa recommends discharge 14 days after symptom onset if clinically stable. We recommend a unified, simpler discharge criteria, based on current studies which suggest that most SARS-CoV-2 loses its infectivity by 10 days post-symptom onset. In asymptomatic cases, this can be taken as 10 days after the first positive PCR result. Additional days of isolation beyond this should be left to the discretion of individual clinician. This represents a practical compromise between unnecessarily prolonged admissions and returning highly infectious patients back to their care facilities, and is of particular importance in older patients discharged to LTCFs, residents of which may be at greatest risk of transmission and worse clinical outcomes.

Background: Disabled people are particularly exposed to the risks of COVID-19, as well as to the measures taken to address it, and their impact. The aim of the study was to examine the disability-inclusiveness of government responses to COVID-19 in four South American Countries: Argentina, Brazil, Chile, and Peru. Methods: We conducted documentary research, using framework analysis to analyse reports, legislation, decrees, and other official documents that communicated measures taken in response to the pandemic, published from February 1st until May 22nd, 2020. We included documents reporting measures that affected disabled people either directly (measures specifically designed for disabled people) or indirectly (measures for the general population). We developed an analytical framework based on recommendations for disability-inclusive response to COVID-19 published by the Economic Commission for Latin America and the Carribean, the World Health Organisation, and other international organisations. Results: We analysed 72 documents. The findings highlight that while some positive measures were taken, the needs of disabled people were not fully considered. Several countries published recommendations for a disability-inclusive response to COVID-19, without ensuring their translation to practice. All countries took at least some steps to ensure access to financial support, health, and education for disabled people, but at the same time they also implemented policies that had a detrimental impact on disabled people. The populations that are most exposed to the impacts of COVID-19, including disabled people living in institutional care, were protected in several cases only by recommendations rather by legislation. Conclusions: This study illustrates how the official government responses taken by four countries in the region – while positive, in several aspects – do not fully address the needs of disabled people, thus further disadvantaging them. In order to ensure response to COVID − 19 is disability inclusive, it is necessary to translate recommendations to practice, consider disabled people both in mainstream policy and in disability-specific measures, and focus on the long-term reconstruction phase.

Patients with rare diseases across the world struggle to access timely diagnosis and state-of-the-art treatment and management of their conditions. Several recently published reviews highlight the importance of country efforts to address rare diseases and orphan drugs policy comprehensively. However, many of these reviews lack depth and detail at the local level, which we believe is necessary for rare disease advocates to identify and prioritize opportunities for strengthening each country's policy framework.We asked leading patient advocates from civil society organizations their views on rare disease public policy in Argentina, Brazil, Chile, Colombia, Mexico, and Peru with a focus on whether specific laws and regulations in these six Latin American countries have been promulgated. From December 2018 to March 2019 we supplemented their perspectives with evidence from accessible literature using key search terms. For each country, we prepared a detailed analysis on how laws or other policy initiatives took shape and the steps taken since to implement them. This allowed us to identify five broad policy categories for subsequent analysis: national laws, national regulations, health system incorporation of rare disease treatments, care delivery, and patient engagement.By describing the different approaches, challenges and timelines across six countries, our research demonstrates that strengthening rare disease policy first requires a common understanding and local consensus of each country's recent past and current situation. Subsequent analysis based on a set of common policy dimensions led us to where we believe salient opportunities lie for each of these countries to strengthen their overall policy framework for rare disease patients.

In this paper, we estimate the causal effect of an extra year of schooling on mathematics performance for seven Latin American countries based on PISA 2012. To that end we exploit exogenous variation in students' birthdates around the school entry cut-off date using both sharp and fuzzy Regression Discontinuity designs. We find strong effects of an extra year of schooling in most countries, which amount to a 30% increase in PISA test scores in Brazil, 18% in Uruguay, 7% in Argentina and 6% in Costa Rica. These effects differ from the typical estimates obtained from simple regressions or multilevel models and are large enough to allow 15-year-old students to reach higher proficiency levels, suggesting significant potential gains of reducing dropout rates in the region. Finally, we stress the importance of taking into account the effects of school entry cut-off dates on PISA samples to avoid making unfair international comparisons.

Burnout is a highly prevalent globalized health issue that causes significant physical and psychological health problems. In Latin America research on this topic has increased in recent years, however there are no studies comparing results across countries, nor normative reference cut-offs. The present meta-analysis examines the intensity of burnout (emotional exhaustion, cynicism and personal accomplishment) in 58 adult nonclinical samples from 8 countries (Argentina, Brazil, Chile, Colombia, Ecuador, Mexico, Peru and Venezuela). We found low intensity of burnout but there are significant differences between countries in emotional exhaustion explained by occupation and language. Social and human service professionals (police officers, social workers, public administration staff) are more exhausted than health professionals (physicians, nurses) or teachers. The samples with Portuguese language score higher in emotional exhaustion than Spanish, supporting the theory of cultural relativism. Demographics (sex, age) and study variables (sample size, instrument), were not found significant to predict burnout. The effect size and confidence intervals found are proposed as a useful baseline for research and medical diagnosis of burnout in Latin American countries. [ABSTRACT FROM AUTHOR]

The academic programs at the graduate level are increasingly interested about the enrollment management challenges in terms of international student mobility. Understanding fundamental enrollment concepts to attract international students provides the essential key to consider the competitive environment concerning university resources, academic program potential, complex cultural dynamics, and workplaces among others. Based on a six-year quantitative and descriptive statistical study, this paper addresses the trends of first-time graduate enrollment and patterns of international student mobility by faculty at the University of Puerto Rico at Mayaguez. Results revealed the sustained trend of graduate enrollment of international students mainly from South America, Central America, and the Caribbean among others. Moreover, the presence of international graduate students adds a dimension of diversity to UPRM between teaching and research undertakings that enhance the Colleges of Engineering, Arts and Sciences, Agricultural Sciences, and Business Administration. The international student mobility has a consistent tendency mainly in the Colleges of Engineering, Arts and Sciences, and Agricultural Sciences. This consistency resembles the quality and reputation recognized by educational institutions and organizational world rankings. In-depth, understanding the trends related to international graduate enrollment and mobility should be considered by institutional leaders and administrators at UPRM to make knowledgeable decisions and to effectively set priorities to recruit highly qualified international students.

Background: Obesity is growing at an alarming rate in Latin America. Lifestyle behaviours such as physical activity and dietary intake have been largely associated with obesity in many countries; however studies that combine nutrition and physical activity assessment in representative samples of Latin American countries are lacking. The aim of this study is to present the design rationale of the Latin American Study of Nutrition and Health/Estudio Latinoamericano de Nutrición y Salud (ELANS) with a particular focus on its quality control procedures and recruitment processes.Methods/design: The ELANS is a multicenter cross-sectional nutrition and health surveillance study of a nationally representative sample of urban populations from eight Latin American countries (Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Perú and Venezuela). A standard study protocol was designed to evaluate the nutritional intakes, physical activity levels, and anthropometric measurements of 9000 enrolled participants. The study was based on a complex, multistage sample design and the sample was stratified by gender, age (15 to 65 years old) and socioeconomic level. A small-scale pilot study was performed in each country to test the procedures and tools.Discussion: This study will provide valuable information and a unique dataset regarding Latin America that will enable cross-country comparisons of nutritional statuses that focus on energy and macro- and micronutrient intakes, food patterns, and energy expenditure.Trial Registration: Clinical Trials NCT02226627.

South America has gained international media attention due to its ongoing arms race, with politicians and analysts warning about the possibility of war. Nevertheless, since the Chaco War in the 1930s, the region has seldom faced major inter-state wars, all of which have been short-lived and with relatively few casualties. This article will discuss in greater detail the ongoing arms race in South America, portraying it as a race 'of levels', with not all countries carrying out massive weaponry purchases. Finally, I will discuss regional geopolitics, geosecurity and integration as part of an analysis regarding the unlikelihood of war. [ABSTRACT FROM AUTHOR]

In 2007, six countries (Argentina, Brazil, Chile, Paraguay, Peru and Uruguay) commenced work on a project to harmonise public policy on school sexuality education (SE) and the prevention of HIV. Inter-sectoral management committees for SE involving ministries of education, ministries of health and civil society were established, national policies and work plans were formulated and implemented, and SE/HIV prevention activities were carried out. The strengths and weaknesses of implementation were assessed. After this, the beginnings of a community of practice were created, with national focal points. This paper analyses the above process using qualitative data generated through semi-structured questionnaires and interviews, with a focus on the perceived contribution of regional collaboration to the development of national policies, national curricula and implementation. Overall, the initiative reached 83,000 teachers and 1,500,000 pupils. Training materials and national curricula and policies were developed, introduced and implemented. Regional collaboration improved political institutionalisation, information exchange, inter-sectoral collaboration, civil society participation, programme legitimacy and the perception of SE as a young person's right. The initiative offers a model for other countries, with regional collaboration helping to establish the case for SE both normatively and institutionally at the political level, mitigate obstacles in the context of such a politically sensitive topic as SE and provide a forum for discussion and the exchange of information which in turn helped legitimise and operationalise national SE policies.

Purpose: This paper aims to determine the level of awareness and implementation of family-responsible parameters: policies, enablers, practices, and culture, in Spanish and Latin-American companies, and how they impact work-life balance. Design/methodology/approach: The study uses data from different national IESE's Family-Responsible Employer Index surveys in Spain (1,000 companies) and five Latin-American countries (1,155 companies), Brazil, Chile, Colombia, El Salvador and Peru, done between 2006 and 2008. This is a structured questionnaire that assesses the stage of development the organization is in regarding four main family-responsible parameters: policies, enablers, practices, and culture. Findings: Latin-American countries get a slightly higher number of companies that are fully supportive of work-family balance environment than Spain, but with lesser formal policies implemented and a stronger presence of enablers and practices. Policies are important but might not be as effective if not accompanied by the example of managers and staff as well as by a deep understanding of the cultural value placed by them on work, family and personal life. Research limitations/implications: The survey-based data used limits insight into causal relationships. Qualitative and longitudinal studies are needed in order to clarify motives for individual and organizational decisions regarding work-life initiatives. Data collected are from one source only: employer's management. Multi-source studies must follow and include the public sector. Originality/value: This is the first comparison between Spanish companies and companies from five Latin-American countries regarding work-family policies, enablers, practices and culture with such an ample number of companies. Findings will aid HRD practitioners in developing work-family initiatives and help researchers to address new questions in cross-cultural comparisons. (Contains 1 figure and 6 tables.)

Based on data from 700 companies in 20 countries, this paper records the research that investigates the contribution of organisational and technological practices to speed up New Product Development (NPD). The organisational practice is found positively correlated with the speed of NPD. However, no significant direct relationship was found between technology practice and the speed of NPD. The organisational and technological practices are found to be in balance, which may be a new input to explain how technology helps NPD. The implication is that organisational practices such as team, continuous improvement and Total Quality Management (TQM) philosophy are needed in order to implement technologies successfully. This result supports the simultaneous theory on innovation, which is especially important in developing countries. (Contains 1 figure and 4 tables.)

Fitting Susceptible-Infected-Recovered (SIR) models to incidence data is problematic when not all infected individuals are reported. Assuming an underlying SIR model with general but known distribution for the time to recovery, this paper derives the implied differential-integral equations for observed incidence data when a fixed fraction of newly infected individuals are not observed. The parameters of the resulting system of differential equations are identifiable. Using these differential equations, we develop a stochastic model for the conditional distribution of current disease incidence given the entire past history of reported cases. We estimate the model parameters using Bayesian Markov Chain Monte-Carlo sampling of the posterior distribution. We use our model to estimate the transmission rate and fraction of asymptomatic individuals for the current Coronavirus 2019 outbreak in eight American Countries: the United States of America, Brazil, Mexico, Argentina, Chile, Colombia, Peru, and Panama, from January 2020 to May 2021. Our analysis reveals that the fraction of reported cases varies across all countries. For example, the reported incidence fraction for the United States of America varies from 0.3 to 0.6, while for Brazil it varies from 0.2 to 0.4., Competing Interests: The authors have declared that no competing interests exist.

In this paper, we group South American countries based on the number of infected cases and deaths due to COVID-19. The countries considered are: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Peru, Paraguay, Uruguay, and Venezuela. The data used are collected from a database of Johns Hopkins University, an institution that is dedicated to sensing and monitoring the evolution of the COVID-19 pandemic. A statistical analysis, based on principal components with modern and recent techniques, is conducted. Initially, utilizing the correlation matrix, standard components and varimax rotations are calculated. Then, by using disjoint components and functional components, the countries are grouped. An algorithm that allows us to keep the principal component analysis updated with a sensor in the data warehouse is designed. As reported in the conclusions, this grouping changes depending on the number of components considered, the type of principal component (standard, disjoint or functional) and the variable to be considered (infected cases or deaths). The results obtained are compared to the k-means technique. The COVID-19 cases and their deaths vary in the different countries due to diverse reasons, as reported in the conclusions.

This paper revisits three major accidents that occurred in South America. The main purpose of this review is to analyze the long term health and other effects of accidental exposures to ionizing radiation in order to extract lessons from these radiological emergencies that might be useful for avoiding similar events (primary prevention) and for preparing the overall response to radiation accidents to mitigate their different impacts (secondary prevention). For that, consults were made on the pertinent literature and use was made of personal information of the authors.

Human cystic echinococcosis (CE) caused by larval Echinococcus granulosus is a zoonosis of major public health importance throughout Latin America. The Andean and South Cone regions have been recognized as endemic areas of cystic echinococcosis. This paper reviews prevalence in Argentina, Chile, Uruguay, Brazil and Peru.

The production of articles resulting from biomedical, clinical, and public health studies that originated in Argentina, Brazil, Chile, Cuba, Mexico, and Venezuela from 1973 through 1992 was analyzed to discover trends in health research in Latin America. From the database of the Institute for Scientific Information (ISI), 41,238 articles with first authors who resided in those countries were extracted. These articles were analyzed by subject area, type of study, country, number of authors and institutions that participated in the investigation, and citations received by each article. Also analyzed were 95 articles in epidemiology selected from a pool of 570 published by authors from the six countries in 11 public health journals that enjoy international prestige. The results showed that the number of published works increased by 117% between the first and last five-year periods within the study period. Clinical research was distributed the most evenly among the countries, and public health research was the most concentrated (60.7% originated in Brazil). The numbers of biomedical and public health research articles showed relatively more growth than those reporting on clinical research throughout the period. A relative decrease was found in articles by only one author, which suggests a greater frequency of team efforts, and an increase was seen in articles with authors tied to two or more national or foreign institutions, which indicates greater cooperation between institutions and countries. The average number of citations received by each article was 3, which was less than half the number received by the articles in the ISI database (7.78). Regarding the subset of 95 articles in epidemiology, the great majority (96%) dealt with infectious diseases or maternal and child health, while in the international literature 78% of such articles were about chronic diseases. This group of articles gave evidence of more cooperation with international institutions and had a citation index of 4.36 per article. It is concluded that, despite the inherent limitations, this type of study reveals some general trends in the development of research in the six Latin American countries with the greatest scientific production and makes it possible to formulate hypotheses on the factors that influence these trends. Taken with the paper caution, the results of studies like this one can be of great value in defining health science and technology policies.

Extent of genic variability among 22 tribal groups of South American Indians in terms of net codon differences per locus has been studied on the basis of determinations on ten genetic systems. The possibility of more than one (other than the north-south route, considered by others) migrational pattern is discussed in the light of the existing genetic variability among the Andean highland and the jungle populations. Genic similarities (as measured by gene identity) are related with geographic proximities which reflect the importance of random genetic drift in creating the present genic divergence among these population groups. Although the materials used in this paper form probably only a non-random sample of structural genome, intralocus variance (sampling) is found to contribute only a little in the variabilities of heterozygosity or genetic distance.

"This paper describes the historical evolution of five populations and analyzes the circumstances under which data on maternal and paternal orphanhood of couples at the moment of marriage were collected and compiled." The data, which concern historical populations in Mexico, Chile, Peru, Brazil, and Argentina, are used to construct life tables for male and female adults. Consideration is given to mortality differentials by sex. (summary in ENG), (excerpt)
