'Their opinion counts as far as you let it'- understanding queer migration in Minas Gerais, Brazil.

The literature regarding the life course and queer migration has shown that many gay men and lesbians seek large cities to live their lives away from the prying eyes of their families and build their sexual identity. In the global south, little is known about the effects that sexuality can have on the migratory trajectories of individuals. In that sense, what happens to the lives of those that have never left their hometowns and have had to find ways to experience their sexuality in these places. Therefore, the aim of this paper is to discuss queer migration, the impact on the lives of the individuals that left their hometowns, others that at one point came back and those that never left in the first place. Based on 21 life course interviews with self-identified LGB individuals in small/medium towns in Brazil, this paper shows how aspects such as closeness to family, educational trajectory, financial stability affects the migration trajectories of LGB individuals that live in small/medium cities. The results show that families are an important influence in the decision-making to migrate, to stay or to return to your hometown.

Current challenges for plant biology research in the Global South.

In an attempt to address the large inequities faced by the plant biology communities from the Global South (i.e. countries located around the tropics and the Southern Hemisphere) at international conferences, this Viewpoint is the reflexive thinking arising from the concurrent session titled 'Arabidopsis and its translational research in the Global South' organized at the International Conference of Arabidopsis Research 2023 (ICAR 2023) in Chiba, Japan in June 2023. Here, we highlight the main obstacles plant biology communities in the Global South face in terms of knowledge production, as measured by the unequal production and citation of publications, investigating and advancing local plant genomics and biodiversity, combating disparities in gender and diversity, and current initiatives to break isolation of scientists.

Measuring student mindsets at scale in resource-constrained settings: A toolkit with an application to Brazil during the pandemic.

Mounting evidence that growth mindset-the belief that intelligence is not fixed and can be developed-improves educational outcomes has spurred additional interest in how to measure and promote it in other contexts. Most of this research, however, focuses on high-income countries, where the most common protocols for measuring and intervening on student mindsets rely on connected devices-often unavailable in low- and middle-income countries' schools. This paper develops a toolkit to measure student mindsets in resource-constrained settings, specifically in the context of Brazilian secondary public schools. Concretely, we convert the computer-based survey instruments into text messages (SMS). Collecting mindset survey data from 3570 students in São Paulo State as schools gradually reopened in early 2021, we validate our methodology by matching key patterns in our data to previous findings in the literature. We also train a machine learning model on our data and show that it can (1) accurately classify students' SMS responses, (2) accurately classify student mindsets even based on text written in other media, and (3) rate the fidelity of different interventions to the published growth mindset curricula.

Like diamonds in the sky? Public perceptions, governance, and information framing of solar geoengineering activities in Mexico, the United Kingdom, and the United States.

Solar geoengineering (also known as solar radiation modification) is garnering more attention (and controversy) among media and policymakers in response to the impacts of climate change. Such debates have become more prominent following the first-ever field trials of stratospheric aerosol injection (SAI) in 2022. How the lay public perceives solar geoengineering remains unclear, however. We use nationally representative samples (N = 3013) in Mexico, United States, and United Kingdom to examine public perceptions of risks and benefits, support, and policy preferences. We also employ an information-framing design that presented individuals with media-style reports on SAI activities differing along three dimensions: location, actor, and scale and purpose. Support for SAI is found to be generally higher in Mexico; perceptions of risks and benefits do not differ between countries. Information about SAI activities has a limited effect. There is evidence that activities conducted by universities receive more support than those by start-up companies.

Research in Latin America from a decolonial perspective: Challenges of producing socially situated knowledge.

The developmental science literature predominantly originates from WEIRD (Western, Educated, Industrialized, Rich, and Democratic) countries. This bias perpetuates colonial power imbalances and marginalizes non-WEIRD societies' knowledge. This special issue addresses this gap by focusing on Latin America, emphasizing the region's diverse socioeconomic, cultural, and political contexts. This commentary contextualizes research in Latin America, and then presents and discusses the articles. Finally, it presents some of the challenges researchers in Latin America face.

Veganism, cuisine, and class: exploring taste as a facilitator in adopting a vegan lifestyle in Santiago, Chile.

Introduction: Veganism is a movement that avoids consuming animal products. This lifestyle is commonly represented as elitist despite the broad range of people who follow it. Using Bourdieu's taste theory, this study analyzes how personal culinary tastes of different social classes generate favorable (or unfavorable) dispositions to adopting veganism. Methods: We analyzed 73 biographical interviews with 40 young vegans in three different waves. Results: The findings reveal that all social classes exhibit favorable dispositions towards veganism. In upper-class individuals, dispositions to embrace healthy and exotic food facilitate the adoption of new flavors and reflexivity in eating practices. Conversely, lower-class individuals have traditional meatless culinary practices rooted in their restricted budget, facilitating the transition to a plant-based diet. Discussion: These results demonstrate the relevance of social class in understanding the diversity of vegan practices, and they contribute to breaking stereotypes around this movement.

The role of Geographic Information Systems in mitigating plastics pollution in the Global South-A spatial analysis of recycling facilities in Costa Rica.

Costa Rica is at the forefront of environmental conservation in Central America, with its focus on sustainability and green practices. Building on this foundation, the country joins a cohort of middle-income developing countries that have set forth ambitious goals to eliminate plastic pollution and become plastics-free. Recycling remains one of the most effective ways of removing plastic waste from the environment. Although GIS has been utilized in environmental research, its use is still expanding in developing countries of the Global South. These countries are experiencing unprecedented adverse climate and ecological impacts while also pursuing fundamental socioeconomic growth. The application of more cost-effective and strategic technological solutions, as well as data-driven decision-making, could fast-track the achievement of their urgent environmental goals. Using Geographic Information Systems (GIS) analysis, this study applies hot spot, location-allocation, and time-distance measures to examine Costa Rica's capacity to recycle plastic waste. Focusing specifically on availability and the public's access to recycling facilities, this article offers insights into the resource constraints and evolution of plastics governance in developing countries with environmentally-focused priorities. The findings of this study suggest that while Costa Rica is implementing progressive plastics regulatory policies, the ability to achieve plastics-free status is hampered by shortfalls in the number and distribution of recycling facilities and the public's access to recycling services. Expanding recycling infrastructure, including transportation, and adopting a less canton-centric waste administration system could contribute to resolving these challenges. This study contributes to discourses on global plastics governance and environmental change management in the Global South.

Integrating perspectives in developing mycorrhizal trait databases: a call for inclusive and collaborative continental efforts.

Global assessments of mycorrhizal symbiosis present large sampling gaps in rich biodiversity regions. Filling these gaps is necessary to build large-scale, unbiased mycorrhizal databases to obtain reliable analyses and prevent misleading generalizations. Underrepresented regions in mycorrhizal research are mainly in Africa, Asia, and South America. Despite the high biodiversity and endemism in these regions, many groups of organisms remain understudied, especially mycorrhizal fungi. In this Viewpoint, we emphasize the importance of inclusive and collaborative continental efforts in integrating perspectives for comprehensive trait database development and propose a conceptual framework that can help build large mycorrhizal databases in underrepresented regions. Based on the four Vs of big data (volume, variety, veracity, and velocity), we identify the main challenges of constructing a large mycorrhizal dataset and propose solutions for each challenge. We share our collaborative methodology, which involves employing open calls and working groups to engage all mycorrhizal researchers in the region to build a South American Mycorrhizal Database. By fostering interdisciplinary collaborations and embracing a continental-scale approach, we can create robust mycorrhizal trait databases that provide valuable insights into the evolution, ecology, and functioning of mycorrhizal associations, reducing the geographical biases that are so common in large-scale ecological studies.

Substance use treatment completion and criminal justice system contact in Chile: A retrospective, linked data cohort study.

BACKGROUND AND AIMS: Substance use treatment (SUT) has shown to be effective in reducing self-reported offending; however, the association between SUT completion and criminal justice system (CJS) contact has been underexplored, especially in Latin America. This study aimed to estimate the association between SUT completion status and (1) any subsequent CJS contact and (2) CJS contact leading to imprisonment, at 1, 3 and 5 years post-discharge, in Chile. DESIGN: Retrospective cohort study using multivariable survival analysis based on linked administrative data from 2010 to 2019. SETTING: This study took place in Chile, where SUT is available at no cost through Chile's publicly funded health-care, and is provided in outpatient and inpatient modalities in public and private centres. PARTICIPANTS: A total of 70 854 individuals received their first SUT from 2010 to 2019. They were mainly males (76.3%), and their main substance used at admission was cocaine paste (39.2%). MEASUREMENTS: SUT completion status included completion, late dropout (≥ 3 months) and early dropout (< 3 months). Outcomes were (1) any CJS contact and (2) CJS contact leading to imprisonment after baseline treatment. We estimated the association between treatment completion and CJS contact through flexible parametric Royston-Parmar models while adjusting for several covariates. FINDINGS: Those who completed SUT (27.2%) were less likely to have any CJS contact at 5 years post-SUT compared with those who dropped out late [with a gap of -9.5%, 95% confidence interval (CI) = -8.7, -10.3] and early (-11.2%, 95% CI = -10.1, -12.3). Also, those who completed SUT were less likely to have CJS contact leading to imprisonment at 5 years post-SUT compared with those who dropped out late (-2.6%, 95% CI = -2.2, -3.1) and early (-4.0%, 95% CI = -3.3, -4.6). These differences were also observed at 1 and 3 years post-SUT for each outcome. CONCLUSIONS: In Chile, completion of substance use treatment appears to be associated with lower probabilities of both any criminal justice system contact and contact leading to imprisonment.

Climate change and long-term human behaviour in the Neotropics: an archaeological view from the Global South.

In this paper, we argue for the inclusion of archaeology in discussions about how humans have contributed to and dealt with climate change, especially in the long term. We suggest Niche Construction Theory as a suitable framework to that end. In order to take into account both human and environmental variability, we also advocate for a situated perspective that includes the Global South as a source of knowledge production, and the Neotropics as a relevant case study to consider. To illustrate this, we review the mid-Holocene Hypsithermal period in the southern Puna and continental Patagonia, both in southern South America, by assessing the challenges posed by this climate period and the archaeological signatures of the time from a Niche Construction Theory perspective. Finally, we emphasize the importance of these considerations for policymaking. This article is part of the theme issue 'Climate change adaptation needs a science of culture'.

Building management and innovation capabilities for global health: a senior executive program.

Accurately approaching the major challenges associated with global health management has become a mandatory key point in the training of medical leaders around the world. The Senior Executive Program in Global Health Innovation Management (SEPGHIM) seeks to provide an answer to the need for innovation and managerial capacity building in Global Health and to address the current detachment between Public Health Organizations and Business Schools. In 2019, SEPGHIM's first edition was led by five prestigious academic institutions on three continents. The first cohort included a total of 27 high-level health professionals and executives from 16 countries with 7-10 years of working experience who participated during the 11 months of the course. The program sought to fill an often-found knowledge gap among health professionals in terms of health innovation, leadership, and management. SEPGHIM relied on multiple pedagogical methods conveyed through a robust theoretical and applied syllabus that included case studies, simulations, guest speakers, debates, site visits, and an executive challenge. The program achieved various results. First, it recruited high-level health professionals that ensured diversity of backgrounds, allowing an exchange of experiences and different ways of addressing global health challenges. Second, it created a network of health professionals for possible future collaborations that can anticipate new trends and opportunities in global health and work together with stakeholders from other sectors. This networking was one of the most highly rated benefits by the students. Finally, the participants expressed great eagerness to recommend the program (4.9 out of 5) to other decision-makers and leaders in the global health field. These results provide positive insights regarding the value of such a training program for senior health professionals.

Health Science Research at a Regional Level: Insights From South America Comment on "The Roles of Regional Organisations in Strengthening Health Research Systems in Africa: Activities, Gaps, and Future Perspectives".

The article seeks to shed light on the role of regional organizations in strengthening health research systems in Africa, how they operate and how they work, as well as debts and future challenges. As can be observed also in South America, the continued strengthening of health research requires strategic thinking about the roles, comparative advantages, and capacity of regional organizations to facilitate the flourishing of health research systems. Health research is a strategic field for the transformation of socio-health inequalities on the one hand and the reduction of regional asymmetries on the other. Thus, regional organizations represent key actors in strengthening health research systems and the regional research agenda reinforces its sovereign condition in the autonomous definition of relevant topics and financing. In this process, integration mechanisms face a great challenge, as shown by the recent pandemic, not only in Africa but also in South America.

A review of ancestrality and admixture in Latin America and the caribbean focusing on native American and African descendant populations.

Genomics can reveal essential features about the demographic evolution of a population that may not be apparent from historical elements. In recent years, there has been a significant increase in the number of studies applying genomic epidemiological approaches to understand the genetic structure and diversity of human populations in the context of demographic history and for implementing precision medicine. These efforts have traditionally been applied predominantly to populations of European origin. More recently, initiatives in the United States and Africa are including more diverse populations, establishing new horizons for research in human populations with African and/or Native ancestries. Still, even in the most recent projects, the under-representation of genomic data from Latin America and the Caribbean (LAC) is remarkable. In addition, because the region presents the most recent global miscegenation, genomics data from LAC may add relevant information to understand population admixture better. Admixture in LAC started during the colonial period, in the 15th century, with intense miscegenation between European settlers, mainly from Portugal and Spain, with local indigenous and sub-Saharan Africans brought through the slave trade. Since, there are descendants of formerly enslaved and Native American populations in the LAC territory; they are considered vulnerable populations because of their history and current living conditions. In this context, studying LAC Native American and African descendant populations is important for several reasons. First, studying human populations from different origins makes it possible to understand the diversity of the human genome better. Second, it also has an immediate application to these populations, such as empowering communities with the knowledge of their ancestral origins. Furthermore, because knowledge of the population genomic structure is an essential requirement for implementing genomic medicine and precision health practices, population genomics studies may ensure that these communities have access to genomic information for risk assessment, prevention, and the delivery of optimized treatment; thus, helping to reduce inequalities in the Western Hemisphere. Hoping to set the stage for future studies, we review different aspects related to genetic and genomic research in vulnerable populations from LAC countries.

Vaccine technology transfer in a global health crisis: Actors, capabilities, and institutions.

The COVID-19 pandemic, which featured international pharmaceutical firms seeking to build global manufacturing networks to scale-up the supply of vaccines, has generated heightened interest in understanding the role of firm-to-firm technology transfer. While considerable attention has been given to tracking the extent of international vaccine technology transfer, we know little about how partnerships were established and work in practice. Understanding the challenges that such projects face, and how such challenges may be overcome, is crucially important. This paper provides an account of the partnership between the British-Swedish multinational pharmaceutical company AstraZeneca, the vaccine developer that has engaged in the most technology transfer and built the widest global manufacturing network, and Bio-Manguinhos, a public laboratory linked to Brazil's Ministry of Health. The case study demonstrates the importance of capabilities and regulatory flexibility. Moreover, the analysis highlights the role of political factors that affect the process of technology transfer, and innovation more broadly. Because of the risks involved and the need to quickly mobilize existing capabilities and build new ones, as well as the imperatives of coordinating among manufacturing and regulatory processes and allocating resources to make such arrangements feasible, technology transfer projects need to be enabled politically. Looking forward, the case study has implications for initiatives to expand technology transfer for broadened production of vaccines in the Global South.

Zooplankton exposure to microplastic contamination in a estuarine plume-influenced region, in Northeast Brazil.

This work describes the spatio-temporal distribution of suspected plastic and microplastic (MP) particles in estuarine plumes and analyzes the microplastic/zooplankton ratio. Subsurface hauls with a conical-cylindrical net were deployed in the coastal area of Tamandare (Pernambuco, Brazil), covering the plume of two rivers and a bay adjacent to coral reefs. A total of 2079 suspected plastic particles were detected, mostly fibers and fragments (>60%). Organic matter digestion was made using a 30% hydrogen peroxide solution, of which approximately 50% of suspected particles were validated as MPs. The average MP abundance was significantly higher during the high rainfall season (53.8 ± 89.6 and 18.8 ± 32.3 particles/m³, respectively), with higher values registered in the plume area (108.9 ± 158.5 and 44.6 ± 55.5 particles/m³). Polymer identification using FT-IR confirmed that suspected particles were mainly polypropylene, polyamide, and polyurethane. These results confirm the hypothesis of a temporal transport variation of MPs from the river to the coastal environments, particularly since the plume influences debris input. Eleven animal phyla were identified, and the subclass Copepoda was predominant (90%), particularly the nauplius stage (70%). Over 70% of verified MPs range between 20 and 2000 µm, equivalent to the most common size of zooplanktonic organisms. Results support that coastal areas near estuarine plumes are exposed to microplastic contamination, affecting species dependent on zooplankton in marine coastal food webs.

The right to dream: A cross-sectional look at poverty alleviation programs.

Studies on social programs reveal the absence of a cross-sectional perspective capable of identifying common aspects that improve the living conditions of their participants while also contributing to poverty alleviation. To detect such elements, we examined the transformations in the experiences and meanings associated with poverty and its alleviation by conducting semistructured interviews and focus groups with participants and intervention team members that implemented six social programs in Chile and Peru. We conducted a descriptive and relational analysis guided by Grounded Theory, which revealed three overarching elements: notions of poverty, notions of the overcoming of poverty, and changes necessary for overcoming poverty. Lastly, based on a complex view of poverty and considering the contributions of community psychology, we propose that interventions in this field must create meaningful relational spaces that restore participants' objective and subjective rights, such as the right to dream.

Vozes do Sul Global: a midiatização dos feminismos em um podcast de mulheres brasileiras pelo mundo / Voces del Sur Global: la mediatización de los feminismos en un podcast de mujeres brasileñas por el mundo / Voices from the Global South: the mediatization of feminisms in a podcast by Brazilian women around the world

Resumo O podcast Femigrantes BR se define como "um espaço de conversa de mulheres feministas e imigrantes pelo mundo". Em maio de 2022, o Femigrantes BR contava com 21 episódios, reunindo histórias de brasileiras que vivem e atuam em diversos países. Na voz das entrevistadas, histórias de vida expandem-se para além do relato pessoal, rico em si mesmo, para conectar-se com estruturas solidamente assentadas como as do racismo e das relações desiguais entre Norte e Sul Global. A partir do objeto e do cenário descritos, procuro investigar qual tem sido a contribuição dos feminismos, enquanto discurso político, para o "empoderamento" dessas mulheres migrantes e analisar como a midiatização do debate feminista reflete na forma como estas atuam na vida pública do país no qual passaram a viver. No esforço para atender a esses pontos, dedico-me a um trabalho imersivo nos meios digitais e, em diálogo com aportes dos estudos feministas da tecnologia, decoloniais, pós-coloniais e da comunicação midiática, intento pensar como ocupação feminista da internet pode potencializar transformações sociais nas estruturas desiguais de gênero e contribuir para desafiar as hierarquias entre Norte e Sul Global.

Abstract The podcast Femigrantes BR is defined as "a space for conversation among feminist-immigrant women around the world". The podcast had 21 episodes, gathering stories of Brazilian women who live and work in several countries. In the voices of the interviewees, life stories expand beyond the personal account and connect with firmly established structures such as racism and the unequal relations between the Global North and South. Taking that object and scenario, I investigate what has been the contribution of feminisms, as political discourse, to the "empowerment" of those migrant women and analyse how the media coverage of the feminist debate reflects on the way they act in the public life of the country in which they now live. In the effort to attend to these points, I engage in an immersion in digital media and, in dialogue with contributions from feminist media, technology, decolonial, postcolonial studies, I discuss how the feminist occupation of the internet can potentiate social transformations in unequal gender structures and contribute to challenge hierarchies between North and Global South.

Por uma bioética queer: perspectivas a partir do Sul Global / For a queer bioethics: perspectives from the Global South

RESUMO O objetivo deste artigo foi investigar as intersecções entre a agenda LGBTI+ e a bioética enquanto campo disciplinar. Esta pesquisa se baseou em análise qualitativa e revisão bibliográfica que englobam tópicos relacionados com bioética, estudos pós-coloniais, teoria queer, direitos humanos e relações internacionais. Por meio de reflexões sobre o contexto político e social que precedeu o surgimento da bioética, com enfoque na interpretação da sexualidade e na identidade de gênero durante os períodos coloniais e imperialistas, buscou-se compreender como as perspectivas históricas influenciaram a evolução da bioética. Além disso, pretendeu-se examinar a consolidação da bioética como um campo disciplinar e área de conhecimento científico, destacando a predominância do principialismo na segunda metade do século XX. Nesse sentido, analisou-se o potencial de uma abordagem feminista na bioética para enfrentar as desigualdades e opressões presentes em sua própria estrutura, com uma visão crítica e reflexiva. Por último, apresentou-se de que forma as contribuições epistemológicas da teoria queer podem subsidiar o desenvolvimento de uma bioética queer, a partir do Sul Global. Essas discussões visam ampliar a reflexão sobre as desigualdades e opressões enfrentadas pelas pessoas LGBTI+ enquanto grupo social no contexto da bioética.

ABSTRACT The aim of this article is to investigate the intersections between the LGBTI+ agenda and bioethics as a disciplinary field. This research is based on a qualitative analysis and bibliographic review that encompasses topics related to bioethics, post-colonial studies, queer theory, human rights, and international relations. Through reflections on the political and social context that preceded the emergence of bioethics, focusing on the interpretation of sexuality and gender identity during colonial and imperial periods, we seek to understand how historical perspectives influenced the evolution of bioethics. Additionally, we aim to examine the consolidation of bioethics as a disciplinary field and area of scientific knowledge, highlighting the predominance of principlism in the second half of the 20th century. In this sense, we will analyze the potential of a feminist approach in bioethics to address the inequalities and oppressions present within its own structure, with a critical and reflexive view. Finally, we intend to present how the epistemological contributions of queer theory can support the development of a queer bioethics, from the Global South. These discussions aim to broaden the reflection on the inequalities and oppressions faced by the LGBTI+ community as a social group within the context of bioethics.
