Research Translation to Promote Urban Health in Latin America: The SALURBAL Experience.

In highly urbanized and unequal Latin America, urban health and health equity research are essential to effective policymaking. To ensure the application of relevant and context-specific evidence to efforts to reduce urban health inequities, urban health research in Latin America must incorporate strategic research translation efforts. Beginning in 2017, the Urban Health in Latin America (SALURBAL) project implemented policy-relevant research and engaged policymakers and the public to support the translation of research findings. Over 6 years, more than 200 researchers across eight countries contributed to SALURBAL's interdisciplinary network. This network allowed SALURBAL to adapt research and engagement activities to local contexts and priorities, thereby maximizing the policy relevance of research findings and their application to promote policy action, inform urban interventions, and drive societal change. SALURBAL achieved significant visibility and credibility among academic and nonacademic urban health stakeholders, resulting in the development of evidence and tools to support urban policymakers, planners, and policy development processes across the region. These efforts and their outcomes reveal important lessons regarding maintaining flexibility and accounting for local context in research, ensuring that resources are dedicated to policy engagement and dissemination activities, and recognizing that assessing policy impact requires a nuanced understanding of complex policymaking processes. These reflections are relevant for promoting urban health and health equity research translation across the global south and worldwide. This paper presents SALURBAL's strategy for dissemination and policy translation, highlights innovative initiatives and their outcomes, discusses lessons learned, and shares recommendations for future efforts to promote effective translation of research findings.

Cancer survival in sub-Saharan Africa (SURVCAN-3): a population-based study

The Cancer Survival in Africa, Asia, and South America project (SURVCAN-3) of the International Agency for Research on Cancer aims to fill gaps in the availability of population-level cancer survival estimates from countries in these regions. Here, we analysed survival for 18 cancers using data from member registries of the African Cancer Registry Network across 11 countries in sub-Saharan Africa. We included data on patients diagnosed with 18 cancer types between Jan 1, 2005, and Dec 31, 2014, from 13 population-based cancer registries in Cotonou (Benin), Abidjan (CÔte d'Ivoire), Addis Ababa (Ethiopia), Eldoret and Nairobi (Kenya), Bamako (Mali), Mauritius, Namibia, Seychelles, Eastern Cape (South Africa), Kampala (Uganda), and Bulawayo and Harare (Zimbabwe). Patients were followed up until Dec 31, 2018. Patient-level data including cancer topography and morphology, age and date at diagnosis, vital status, and date of death (if applicable) were collected. The follow-up (survival) time was measured from the date of incidence until the date of last contact, the date of death, or until the end of the study, whichever occurred first. We estimated the 1-year, 3-year, and 5-year survival (observed, net, and age-standardised net survival) by sex, cancer type, registry, country, and human development index (HDI). 1-year and 3-year survival data were available for all registries and all cancer sites, whereas availability of 5-year survival data was slightly more variable; thus to provide medium-term survival prospects, we have focused on 3-year survival in the Results section. 10 500 individuals from 13 population-based cancer registries in 11 countries were included in the survival analyses. 9177 (87·4%) of 10 500 cases were morphologically verified. Survival from cancers with a high burden and amenable to prevention was poor: the 3-year age-standardised net survival was 52·3% (95% CI 49·4-55·0) for cervical cancer, 18·1% (11·5-25·9) for liver cancer, and 32·4% (27·5-37·3) for lung cancer. Less than half of the included patients were alive 3 years after a cancer diagnosis for eight cancer types (oral cavity, oesophagus, stomach, larynx, lung, liver, non-Hodgkin lymphoma, and leukaemia). There were differences in survival for some cancers by sex: survival was longer for females with stomach or lung cancer than males with stomach or lung cancer, and longer for males with non-Hodgkin lymphomas than females with non-Hodgkin lymphomas. Survival did not differ by country-level HDI for cancers of the oral cavity, oesophagus, liver, thyroid, and for Hodgkin lymphoma. For cancers for which population-level prevention strategies exist, and with relatively poor prognosis, these estimates highlight the urgent need to upscale population-level prevention activities in sub-Saharan Africa. These data are vital for providing the knowledge base for advocacy to improve access to prevention, diagnosis, and care for patients with cancers in sub-Saharan Africa.

Perspectives and Opportunities for Learning Analytics Integration

The adoption of learning analytics (LA) in higher education institutions (HEIs) in Mexico is still at an early stage despite increasing global interest and advances in the field. The use of educational data remains a challenging puzzle for many universities, which strive to provide students, teachers, and institutional administrators with information and insights to better understand their performance. The objective of this study was to identify the perspectives of teachers, students, and administrators about the use of educational data to explore opportunities for the adoption and integration of LA in three different Mexican universities. A qualitative approach was used, adopting instruments and guidelines previously developed in the framework of Learning Analytics for Latin America (LALA) project, adapting them to the Mexican context. Methods included 1) structured interviews with high-level institutional administrators and 2) focus groups with students, teachers, and other educational administrators. Results showed that perceptions are oriented toward improving school performance through data-based feedback, with ethical responsibility. Emergent categories were physical and mental health, development of healthy relationships and well-being, feedback style, and governance in a bureaucratic setting. The specific modern construct of LA still needs to be internalized and disseminated to Mexican universities’ educational stakeholders to increase the likelihood of successful adoption.

Associations of Medical Debt With Health Status, Premature Death, and Mortality in the US

Medical debt is increasingly common in the US. Little is known regarding its association with population health. To examine the associations of medical debt with health status, premature death, and mortality at the county level in the US. This cross-sectional study was conducted at the US county level using 2018 medical debt data from the Urban Institute Debt in America project linked with 2018 data on self-reported health status and premature death from the County Health Rankings & Roadmaps and with 2015 to 2019 mortality data from the National Center for Health Statistics. Data analysis was performed from August 2022 to May 2023. Share of population with any medical debt in collections and median amount of medical debt. Health status was measured as (1) the mean number of physically and mentally unhealthy days in the past 30 days per 1000 people, (2) the mean number of premature deaths measured as years of life lost before age 75 years per 1000 people, and (3) age-adjusted all-cause and 18 cause-specific mortality rates (eg, malignant cancers, heart disease, and suicide) per 100 000 person-years. Multivariable linear models were fitted to estimate the associations between medical debt and health outcomes. A total of 2943 counties were included in this analysis. The median percentage of the county population aged 65 years or older was 18.3% (IQR, 15.8%-20.9%). Across counties, a median 3.0% (IQR, 1.2%-11.9%) of the population were Black residents, 4.3% (IQR, 2.3%-9.7%) were Hispanic residents, and 84.5% (IQR, 65.7%-93.3%) were White residents. On average, 19.8% (range, 0%-53.6%) of the population had medical debt. After adjusting for county-level sociodemographic characteristics, a 1-percentage point increase in the population with medical debt was associated with 18.3 (95% CI, 16.3-20.2) more physically unhealthy days and 17.9 (95% CI, 16.1-19.8) more mentally unhealthy days per 1000 people during the past month, 1.12 (95% CI, 1.03-1.21) years of life lost per 1000 people, and an increase of 7.51 (95% CI, 6.99-8.04) per 100 000 person-years in age-adjusted all-cause mortality rate. Associations of medical debt and elevated mortality rates were consistent for all leading causes of death, including cancer (1.12 [95% CI, 1.02-1.22]), heart disease (1.39 [95% CI, 1.21-1.57]), and suicide (0.09 [95% CI, 0.06-0.11]) per 100 000 person-years. Similar patterns were observed for associations between the median amount of medical debt and the aforementioned health outcomes. These findings suggest that medical debt is associated with worse health status, more premature deaths, and higher mortality rates at the county level in the US. Therefore, policies increasing access to affordable health care, such as expanding health insurance coverage, may improve population health.

Cost, time and environmental impact in the execution of mine closure coverage with geosynthetics

Between 10 and 20 years have passed in which several countries of the South American region began declaration processes of mine closures to the respective countries in which mining companies operate. Several of these declared projects initiates actual closure processes, in dumps, tailings deposits, leaching pads, and pits. During the closure process with the use only of granular and cohesive materials; it has been observed that its extraction and placement have presented serious problems of excessive costs, lack of availability, long execution times and environmental problems due to the process of closing the borrow material areas used. This leads to observe if improvements can be made in this type of projects with the use of Geosynthetics. After more than 30 years of using geosynthetics in mining operation projects in South America, they have shown that they can be more efficient in cost and time, in addition to providing less impact benefits when used. In papers presented at other conferences on the design methodology of mine closure covers with geosynthetics, as well as methodologies for estimating the durability, they have left a precedent for their applicability and how to design them as a substitute for soils in this type of project. Experiences of coverages built following these methodologies available up to date have also been presented in congresses. This work focuses on making economic comparisons obtained by using geosynthetics in mine closure covers, as well as the time savings that can be obtained with the benefits of high quality installation using geosynthetics. The issue of impact generated by the lower consumption of fossil fuel and borrow material sites that will later require more closing work is also focused. Comparisons of these issues are presented, in order to share information to designers, project managers and environmental officials who have to deal with mine closure covers.

Climate hazards in Latin American cities: Understanding the role of the social and built environments and barriers to adaptation action

Climate hazards threaten the health and wellbeing of people living in urban areas. This study characterized reported climate hazards, adaptation action, and barriers to adaptation in 124 Latin American cities, and associations of climate hazards with urban social and built environment characteristics. We examined cities that responded to a global environmental disclosure system and that were included in the Urban Health in Latin America (SALURBAL) Project database.The cities studied reported a median of three climate hazards. The most reported hazards were storms (61%) water scarcity (57%) extreme temperature (52%) and wildfires (51%). Thirty-eight percent of cities reported four or more distinct types of hazards. City size, density, GDP, and greenness were related to hazard reports, and although most cities reported taking actions to reduce vulnerability to climate change, 23% reported no actions at all. The most frequently reported actions were hazard mapping and modeling (47%) and increasing vegetation or greenspace coverage (45%). Other actions, such as air quality initiatives and urban planning, were much less common (8% and 3%, respectively). In terms of challenges in adapting to climate change, 35% of cities reported no challenges. The most frequently reported challenges were urban environment and development (43%) and living conditions (35%). Access to data, migration, public health, and safety/security were rarely reported as challenges. Our results suggest that climate hazards are recognized, but that adaptation responses are limited and that many important challenges to response action are not fully recognized.This study contributes to understanding of local priorities, ongoing actions, and required support for urban climate vulnerability assessment and adaptation responses. Findings suggest the need for future research documenting local perceptions of climate hazards and comparison with documented climate hazards.

Spatial data collection and qualification methods for urban parks in Brazilian capitals: An innovative roadmap.

Urban parks have been studied for their effects on health and the environment. Accessing park data from reliable and comparable sources remains challenging, reinforcing the importance of standardized search tools, notably in Latin America. We designed a systematized methodology to identify processes of accessing, collecting, verifying, and harmonizing urban park spatial data in all Brazilian capitals included in the Urban Health in Latin America (SALURBAL) project. We developed a research protocol using official and non-official sources combining the results of Google Maps (GMaps) points and OpenStreetMap (OSM) polygons-GMaps-OSM. Descriptive analyses included the frequency of the distribution of parks before and after harmonization stratified by data source. We used the intraclass correlation coefficient (ICC) to assess agreement in the area between official and GMaps-OSM data. Official data were obtained for 16 cities; for the remaining 11 capitals, we used GMaps-OSM. After verification and harmonization, 302 urban parks were obtained from official data and 128 from GMaps-OSM. In a sub-study of the 16 cities with official data (n = 302 parks), we simulated a collection of non-official data using GMaps-OSM and OSM only. From GMaps-OSM, we obtained 142 parks, and from OSM, 230 parks. Statistical analysis showed a better agreement between official data and OSM. After completing verification and harmonization, the complete dataset (official and GMaps-OSM) included 430 urban parks with a total area of 145.14 km2. The mean number of parks across cities was 16, with a mean size area of 0.33 km2. The median number of parks was nine, with a median area of 0.07 km2. This study highlights the importance of creating mechanisms to access, collect, harmonize, and verify urban park data, which is essential for examining the impact of parks on health. It also stresses the importance of providing reliable urban park spatial data for city officials.

Effects of an urban cable car intervention on physical activity: the TrUST natural experiment in Bogotá, Colombia

Cable cars are part of the transport system in several cities in Latin America, but no evaluations of their effects on physical activity are available. TransMiCable is the first cable car in Bogotá, Colombia, and the wider intervention includes renovated parks and playgrounds. We assessed the effects of TransMiCable and the wider intervention on physical activity. The Urban Transformations and Health natural experiment was a prospective quasi-experimental study conducted from Feb 1, 2018, to Dec 18, 2018 (baseline, pre-intervention) and from July 2, 2019, to March 15, 2020 (post-intervention follow-up) in the TransMiCable intervention area (Ciudad Bolívar settlement) and a control area without TransMiCable (San Cristóbal settlement). A multistage strategy was used to sample households in each area, with one adult (aged ≥18 years) per household invited to participate. Eligible participants had lived in the intervention or control areas for at least 2 years and were not planning to move within the next 2 years. Physical activity was assessed among participants in the intervention and control areas before and after the inauguration of TransMiCable in Ciudad Bolívar with the International Physical Activity Questionnaire (long form) and with wearable accelerometers. Complete cases (those with baseline and follow-up data) were included in analyses. Respondents were classed as being physically active if they met 2020 WHO guidelines (≥150 min per week of moderate activity, ≥75 min per week of vigorous activity, or equivalent combinations); and accelerometery data were classified with the Freedson cut-points for adults. Data were also gathered in zonal parks (area ≥10 000 m2) and neighbourhood parks (area <10 000 m2) in the intervention and control areas by direct observation with the System for Observing Play and Recreation in Communities, to assess levels of physical activity before and after the TransMiCable intervention. Multilevel regression models were used to assess changes in physical activity associated with the TransMiCable intervention. Physical activity questionnaires were completed by 2052 adult participants (1289 [62·8%] women and 763 [37·2%] men; mean age 43·5 years [SD 17·7]) before the inauguration of TransMiCable. After the inauguration, the follow-up (final) questionnaire sample comprised 825 adults in the intervention group and 854 in the control group, including 357 adults in the intervention group and 334 in the control group with valid accelerometery data. 334 (40·5%) of 825 participants in the intervention group reported levels of physical activity that met the 2020 WHO guidelines during walking for transport before the intervention, and 426 (51·6%) afterwards (change 11·1 percentage points [95% CI 6·4 to 15·9]). A similar change was observed in the control group (change 8·0 percentage points [3·4 to 12·5]; adjusted odds ratio [OR] for the time-by-group interaction, intervention vs control group: 1·1 [95% CI 0·8 to 1·5], p=0·38). Time spent doing moderate-to-vigorous physical activity, measured with accelerometers, did not change in the intervention group after the inauguration of TransMiCable (change -0·8 min per day [-4·6 to 3·0]) and did not change compared with the control group (adjusted β for the time-by-group interaction: 1·4 min per day [95% CI -2·0 to 4·9], p=0·41). Moderate-to-vigorous physical activity was 52·1 min per day (SD 24·7) before and 59·4 min per day (35·2) after the inauguration of TransMiCable in new regular users who reported using TransMiCable during mandatory trips for work or education (n=32; change 7·3 min per day [-22·5 to 7·9]). After the intervention, an increase in the proportion of male individuals engaging in moderate or vigorous physical activity was observed in a renovated zonal park (adjusted OR for the time-by-group interaction, intervention vs control park: 2·7 [1·1 to 6·8], p=0·033). Female users of a renovated neighbourhood park were less likely to become engaged in moderate or vigorous physical activity than female users of the control area neighbourhood park (adjusted OR for the time-by-group interaction: 0·4 [0·1 to 0·6], p=0·019). It is encouraging that walking for transport remained high in the TransMiCable intervention area when the use of private motorised transport had increased elsewhere in Bogotá. In low-income urban areas, where transport-related walking is a necessity, transport interventions should be focused on efforts to maintain participation in active travel while improving conditions under which it occurs.

Environmental conflict and the expansion of renewable energy in Central America: exploring Canadian participation

ABSTRACT As capacity to generate and distribute renewable energy expands across Central America, environmental conflict is on the rise, with communities confronting dispossession of water and territory. Renewable energy holds a central position within the extractivist economic model in the region, but little is known about the involvement of Canada in Central American renewable energy sectors. This paper addresses that gap by asking what role Canada plays within a scenario of expanding and conflictual renewable energy projects across Central America. We combine Canadian public records with data from projects, including GeoComunes and the Environmental Justice Atlas, to analyze 726 renewable energy and 162 traditional extractive projects in Central America, and to connect 156 of these projects to evidence of conflict with surrounding communities. While Canadian private companies own very few renewable energy projects in Central America, we argue that this does not imply an absence of Canadian involvement. Instead, the paper explores Canadian participation at multilateral venues, support for energy projects by the federal government, and the benefits that renewable energy expansion presents to the Canadian private sector. The invisibility of the Canadian presence in Central American renewable energy, we suggest, serves to obscure Canadian responsibility for a scenario defined by high levels of conflict.

The affective turn in museums and the rise of affective curatorship

ABSTRACT This article examines the affective turn in museums: what does it mean for museum theory and practice? How can we theorize its effects? In order to address these questions, the article develops the concept of ‘affective curatorship’, denoting curatorial approaches specifically aimed to affect visitors emotionally. Drawing on recent museological literature and exhibition projects in Europe and North America, the article exemplifies the qualities of affective curatorship and examines how emotions can be leveraged in curatorial practice in connection with the exhibition theme, activities, design, and the senses. The main finding is that affective curatorship is subtly transforming curatorial practice and, through that, the way we think and feel about museums. As a curatorial, theoretical and analytical perspective, affect offers crucial insights into the new roles that museums can play in increasingly emotionally demanding times.

Smart Cities as “Big Brother Only to the Masses”: The Limits of Personal Privacy and Personal Surveillance

Smart city projects in Europe and North America are employing a novel approach to data analysis that processes hardly any or no personal data at all. As such, these projects—at least, for the most part—escape the scope of (European) data protection law. The idea behind this new approach to smartness can be condensed in the statement: “smart cities are only Big Brother to the masses.” In other words, if the data collected within smart city projects do not identify any individuals, then there are no issues with privacy and data protection law. This problematic assumption relies on two reductive understandings of key notions in this context: that of “personal privacy” and “personal surveillance.” In this contribution, I focus on the latter and call for a broader understanding of surveillance as a set of diverse modes of social control by privacy law scholars. After all, in order to reveal the underlying dynamics of power and how these might lead to surveillance abuse—even, or especially, when surveillance is based on the processing of seemingly non-personal data—concrete surveillance practices and their logics need to be examined. For this purpose, I take the example of the Stratumseind Living Lab in the Netherlands and examine it through the lens of Foucault’s notion of security. This examination leads to two valuable insights for privacy and data protection law scholars. First of all, it strengthens the argument of contemporary group privacy scholars that a narrow focus on individual privacy and surveillance is inadequate and that the regulatory framework needs to be adapted. The second insight raises another broad issue: smart cities, which function according to the securitizing logic of surveillance, such as the Stratumseind Living Lab, are transforming public spaces into consumption spaces. Yet, the protection of privacy in public can and should serve to protect key aspects of public space—political participation and sociability—as well.

Can't buy me acceptance? Financial benefits for wind energy projects in Germany

Local opposition to wind energy projects in Europe and North America is growing. This often causes project delays or even failure. Financial benefits may be one way to counteract a lack of community support. This analysis seeks to explain how discounted electricity, payments to the municipality, and payments for social purposes shift the acceptance of communities about a local wind energy project. A choice-based conjoint analysis among 811 German citizens showed that financial benefits increase citizens’ acceptance of a hypothetical wind energy project in the close vicinity of their homes. Proponents and the large group of citizens with rather weak preferences for local wind energy projects appreciate all tested benefits. In contrast, benefits cannot win over the small group of opponents. The study provides evidence that benefits do not ensure the perception of fair distributive justice, even for citizens with weak preferences. The findings inform current policies that introduce benefit schemes for wind energy projects to foster community acceptance and win over majority support for projects.

Carbon‐sensitive pedotransfer functions for plant available water

AbstractCurrently accepted pedotransfer functions show negligible effect of management‐induced changes to soil organic carbon (SOC) on plant available water holding capacity (θAWHC), while some studies show the ability to substantially increase θAWHC through management. The Soil Health Institute's North America Project to Evaluate Soil Health Measurements measured water content at field capacity using intact soil cores across 124 long‐term research sites that contained increases in SOC as a result of management treatments such as reduced tillage and cover cropping. Pedotransfer functions were created for volumetric water content at field capacity (θFC) and permanent wilting point (θPWP). New pedotransfer functions had predictions of θAWHC that were similarly accurate compared with Saxton and Rawls when tested on samples from the National Soil Characterization database. Further, the new pedotransfer functions showed substantial effects of soil calcareousness and SOC on θAWHC. For an increase in SOC of 10 g kg–1 (1%) in noncalcareous soils, an average increase in θAWHC of 3.0 mm 100 mm–1 soil (0.03 m3 m–3) on average across all soil texture classes was found. This SOC related increase in θAWHC is about double previous estimates. Calcareous soils had an increase in θAWHC of 1.2 mm 100 mm–1 soil associated with a 10 g kg–1 increase in SOC, across all soil texture classes. New equations can aid in quantifying benefits of soil management practices that increase SOC and can be used to model the effect of changes in management on drought resilience.

Space and Asteroid Mining

Space mining is the name of complicated studies that involve the search for minerals, elements and water from asteroids and minor planets that are close to our world. In particular, the policy of commercializing and financing some products used in space technology, which began in the 1980s, led to the start of extensive development projects in America, Japan and Europe. For this reason, space technology has turned into a way in which we work together, directly or indirectly, with its structure that also enters our lives, its financial structure financed by the whole world, and the scientific cycle of technologies obtained from the working area. Every work done for life in space, settlement, movement, mining, every development will create a serious change in our life on earth.

O Paradoxo da Política Externa Brasileira

Este artigo tem como objetivo discutir a política externa brasileira para a América do Sul a partir da perspectiva da infraestrutura regional. Apesar de ter sido o principal ator na criação da Iniciativa para a Integração da Infraestrutura Regional Sul-Americana (IIRSA), e posteriormente da União das Nações Sul-Americanas (UNASUL), o governo brasileiro foi se afastando das instituições regionais e de seus compromissos declarados para a região. Ainda que grande parte da bibliografia existente no tema defenda que o Banco Nacional de Desenvolvimento Econômico e Social (BNDES) tenha sido o principal financiador dos projetos de integração da infraestrutura regional na América do Sul, ao analisar os documentos e dados disponíveis tal afirmação não se sustenta. O paradoxo a ser discutido neste artigo se apresenta na premissa da utilização do espaço regional para a alavancagem dos compromissos e interesses nacionais através da política externa brasileira de 2000 a 2016.

The Network Entropy as a Measure of a Complexity for Project Organizational Structures

The selection of an organizational structure is one of the most important decisions to make when executing a project. The form of the structure will define the authority, the relationships between the members of the project, where each member is located, the lines of coordination, control, etc. There exists a wide array of quantitative metrics that may be used to measure the complexity of a project organizational structure and that are borrowed from other fields. In this paper, we adopt a metric developed from Shannon’s information entropy, the network entropy, which is a useful metric to measure the complexity of a project organizational structure linking the complexity of the structure to its functional role. The measure is applied to the project organizational structure of an international company dedicated to the development, construction, and operation of renewable energy projects in Europe, Asia, and America. Additionally, and for comparative purposes, alternative organizational structures are considered for the company. Our results show that adopting an organizational structure different from the structure that the company is currently using, the company would reduce its complexity and improve its structural agility and performance.
