What happens when the architectures of extraction, once intimately constituted by capitalist and racial forms of exclusion, begin to rot? Focusing on a Bolivian tin mine, this paper examines the social effects of deteriorating "architectures of extraction," a category that includes both aboveground infrastructures and belowground networks of tunnels and scaffolding. First, I argue that when Llallagua's extractive architecture was built, it helped shore up a connection between tin mining, working-class identity, and revolutionary nationalism – which in turn became bound up with mestizaje, an ideology of racial and cultural whitening. Second, I argue that the ruination of this extractive architecture has had ambivalent implications for the racial politics of contemporary small-scale mining operations that continue to operate inside the mountain. On the one hand, the rotting structures reinforce regional racial hierarchies in a variety of ways, but on the other hand, the slow degradation of the physical structures has made the corresponding social structures more porous, if not fully permeable, to members of regional Indigenous ayllus. While access to the financial benefits of mining is far from unambiguously liberatory, this paper nevertheless suggests that the political possibilities contained within the ruins of extractive architectures are not uniformly adverse.

With its proclamation of universal suffrage in 1952, Bolivia fits into Samuel Huntington's "second short wave of democratization" (1943–1963). In 1952, all women and men gained the right to vote, marking a significant step towards democratization by including previously excluded groups. Literate women had already obtained municipal voting rights in 1945 under a populist government aiming for broader political participation. However, women first voted in 1947, after the oligarchy overthrew this government in 1946 and sought to regain power by repressing the opposition parties and previously marginalized sectors. Unexpectedly, it supported women's suffrage for national elections by the late 1940s. What prompted various political parties to support women's suffrage in the late 1940s? This paper explores how women in Bolivia gained the right to vote and what role the feminist movement and power struggles played in obtaining women's suffrage. Beginning in the 1920s with a study of the emergence of the feminist movement and its evolution during the decades of the 1930s (the Chaco War) and 1940s, the paper culminates with an assessment of feminism's impact on public opinion as well as the importance of the growing politicization of women in the 1940s.

Stand-alone price analysis of illicit opium and coca does not explain why smallholders turn to illicit crops for coping and survival. Under conditions of precarity, illicit crop markets can stimulate productivity. They generate returns that can tame crises and relieve pressures. To smallholders facing marginalisation, violence, and climate change – growing opium and coca, despite their illegality, can reduce or spread risks and provide more predictability. Thus, rather than fix on the 'invisible hand' of price theory, the focus should be on the 'visible hand' of political entrepreneurship, interdependent relationships, and the metrics of precarity. To do this, this paper retrospectively compares illicit crop prices before and after certain historical moments in Bolivia, Myanmar, Colombia, and Afghanistan. [ABSTRACT FROM AUTHOR]

In many countries, the advancement of hydropower resources has been hindered by economic factors and insufficient data on topography, streamflow, environmental sensitivity, power grid, and, most importantly, the location of potential hydropower sites. This challenge is particularly pronounced in certain African and Latin American river systems. Developing web-based maps of hydropower resources based on geographic information systems and advanced mapping technologies can facilitate the initial assessment of hydropower sites. This is especially relevant for developing sites in remote areas and data-scarce regions. The available geospatial datasets, remote sensing technologies, and advanced GIS modelling techniques can be used to identify potential hydropower sites and assess their preliminary characteristics. This paper reviews web-based hydropower atlases in African and Latin American countries. Their main features are represented and compared with the recently launched HYPOSO map viewer covering two African countries (Cameroon and Uganda) and three Latin American countries (Bolivia, Colombia, and Ecuador). This hydropower atlas consists of 20 spatial layers. Its particular focus is to present a geospatial dataset of new hydropower sites with concise information for potential investors. These so-called virtual hydropower atlases can be only one type of discovery at the early project stage, automatically identifying sites worthy of further investigation. A formal validation of the web-based atlases, including the HYPOSO hydropower atlas, is briefly considered. Creating open-access hydropower map viewers is anticipated to significantly enhance the hydropower development database in these nations, offering valuable insights for small and medium-scale projects.

In this paper, we compare practices of formulating responses to requests for confirmation oriented toward confirmation but doing less or more than that in German and Yurakaré (isolate, Bolivia). The German particle joa is identified as a versatile resource for navigating the functional spectrum of such responses, being deployed for less than confirming in terms of epistemic or propositional downgrading, and for more than confirming in terms of addressing terms of questions or a confirmable's valence. When exercising these specific tasks, speakers of Yurakaré, in contrast, rely mostly on repetitional strategies, while a highly specialised particle constitutes an 'escape strategy' when a repeat would convey unwanted implications. We propose that doing less and more than confirming is contingent on a more fundamental distinction: a preference for particles (German) vs. repeats (Yurakaré) in the realm of plain confirmation, which carries over to responses doing less and more than confirming.

Historically, Latin America has been a fertile ground for the emergence of populism. Scholars have identified several waves of populist governments flourishing in the region during the last century. The third wave began in the 2000s when leftist leaders came to power in some Latin American countries, a phenomenon called "the Pink Tide". Two of the most notable examples of populist governments in this wave were Evo Morales in Bolivia (2006-2019) and Rafael Correa in Ecuador (2007-2017). Both leaders promoted an anti-elitist rhetoric highlighting a confrontational divide between domestic elites (as perpetrators of injustices) and the people (as victims). This rhetoric also involved external actors. The relationship with the great powers was permeated by the populist discourse based on the logic of "them vs. us". In this context, the paper analyses the rhetoric of Evo Morales and Rafael Correa concerning the role of the European Union in their countries. Primary sources (speeches, press releases and official documents) are examined to understand the image built around the EU and to grasp how populist rhetoric portrayed the EU's role in areas such as trade and migration. The result is a complex assessment of the ideas about the EU disseminated by these leaders, examining how Morales's and Correa's rhetoric evolved over the years and identifying similarities and differences between their approaches.

Policy entrepreneurs interact with their wider social environment to create social and policy change. To understand entrepreneurial behavior in this context, adopting multi‐level approaches becomes increasingly important. They are crucial to explaining the interdependencies of individual entrepreneurs, immediate stakeholders (such as team members), and their wider context. Scholars focus on specific links, such as those between entrepreneurs and their local community. Very few papers have to date take a holistic approach, even though studying how entrepreneurs interact with multiple levels of stakeholders over time has the potential to better explain entrepreneurial processes. By following a qualitative research approach using two case studies of policy entrepreneurs in Bolivia and Germany, we show that policy entrepreneurs employ different modes of action over time when interacting with their immediate and wider contexts in attempting to foster policy change. Our results suggest that they co‐create with policymakers in order to shape their ecosystems and society at large. [ABSTRACT FROM AUTHOR]

Indigenous Peoples are gaining renewed attention within both policy and academia, as examples of “resilience” and of non‐humanist, non‐modern ways of relating to nature, which might, it is hoped, provide tools to withstand the socio‐ecological crises associated with “the Anthropocene”. This paper argues that such representations obscure both their own colonial foundations and the ongoing forms of racialised dispossession and ecocide faced by Indigenous Peoples today. Instead, we conceptualise indigeneity and nature as deeply entangled categories that are co‐produced with capitalist modernity. Engaging anti‐colonial and Marxist scholarship, and drawing on our long‐term research with Indigenous movements in Bolivia and Colombia, we highlight how discursive and material assemblages of indigeneity and nature are dialectically linked to capitalist processes of dispossession and subaltern efforts to contest these. We further highlight how romanticised accounts of non‐modern nature‐cultures are unsettled by the violent world‐making of colonial capitalism and the unequal burdens placed on Indigenous territories and bodies. We use an ethnographic vignette from the Bolivian Chaco to illustrate the messy everyday ways in which real Indigenous people navigate, contest, endure, and make do amidst the contradictory processes of racialisation, dispossession, and conditional recognition that characterise their positioning within colonial capitalism. In doing so, we show how thinking from the sacrifice zones of extractive capitalism unsettles contemporary debates on decolonising nature in the Anthropocene. [ABSTRACT FROM AUTHOR]

Knowledge on seed ecology is foundational for effective seed‐based restoration including seedling production, direct seed sowing, topsoil transplant, and natural regeneration. Consequently, quantifying available knowledge and biases in seed‐based research allows practitioners to better plan and implement seed‐based restoration programs and identify research priorities. Using a systematic review comprising 45 papers, 401 species, and 2,415 case studies, we provide an overview of seed ecology research in the Pantanal, the world's largest tropical wetland. We identified geographic, taxonomic, and ecological biases, as well as knowledge gaps in seed functions including production, dispersal, dormancy, germination, predation, and stress tolerance. Studies concentrated near large cities resulting in extensive unexplored sites in central Pantanal, in Paraguay, and in Bolivia. Unexpectedly, the most studied species were conducted with dry‐fruited, terrestrial forbs, or shrubs with autochoric or zoochoric dispersal syndromes. Seed banks, stress tolerance, and dispersal were the most studied topics, whereas studies on dormancy and seedling establishment remain rare. We also found disproportionate research interest across the angiosperm tree of life with many examples of underrepresented and overrepresented families. Altogether, persistent knowledge gaps in seed‐based research in the Pantanal hinder upscaling restoration programs and consequently the likelihood of achieving the targets of UN Decade of Ecosystem Restoration. We propose an integrated agenda consisting of a series of orchestrated actions to overcome such barriers, close biodiversity knowledge shortfalls, and promote successful large‐scale restoration programs in the Pantanal.

The Tropical Andes, one of the world's most biodiverse regions, is vital for ecological research and conservation. However, while researchers in Bolivia, Ecuador, and Peru contribute significantly to scientific knowledge, their publication rates in academic journals have historically lagged behind neighboring nations. A multifaceted strategy was employed to understand and address the publication divide in the Tropical Andes region. This approach focused on regional researchers and consisted of a three-day workshop to improve scientific writing skills, offer publication insights, and equip researchers with tools to overcome obstacles. A series of surveys were also conducted to explore the challenges faced by local researchers and their proposed solutions, covering topics such as participant demographics, factors contributing to lower publication rates, personal barriers, proposed strategies for improving publications, specific topics of interest, participant satisfaction, most valuable workshop topics, and future recommendations. The workshop had an overwhelming response, with over 500 interested participants registering in just a few days, mostly experienced professionals, highlighting the need for such initiatives in the region. About two-thirds had ready-to-publish materials, highlighting the potential impact of targeted interventions on unlocking untapped knowledge. The surveys revealed the challenges contributing to the publication divide, including insufficient training, cultural emphasis on economic development, language barriers, limited resource access, lack of institutional support, high publishing costs, and time and financial constraints. The most common personal barriers were insufficient knowledge and experience in the publication process, lack of self-confidence, and fears of rejection. Proposed solutions include conducting training workshops, fostering collaborative networks, improving resource accessibility, and an institutional and cultural shift that encourages publishing. Addressing challenges faced by experienced professionals in the Tropical Andes by understanding individual needs, fostering support, and demystifying the publication process offers a promising path to closing the publication divide and unlocking the region's valuable scientific contributions.

Let G be an abelian group with identity 0 and let R be a commutative graded ring of type G with nonzero unity. Let I(R) be the set of all ideals of R and let δ : I(R) −→ I(R) be a function. Then, according to (R. Abu-Dawwas, M. Refai, Graded δ-Primary Structures, Bol. Soc. Paran. Mat., 40 (2022), 1-11), δ is called a graded ideal expansion of a graded ring R if it assigns to every graded ideal I of R another graded ideal δ(I) of R with I ⊆ δ(I), and if whenever I and J are graded ideals of R with J ⊆ I, we have δ(J) ⊆ δ(I). Let δ be a graded ideal expansion of a graded ring R. In this paper, we introduce and investigate a new class of graded ideals that is closely related to the class of graded δ-primary ideals. A proper graded ideal I of R is said to be a graded 1-absorbing δ-primary ideal if whenever nonunit homogeneous elements a, b, c ∈ R with abc ∈ I, then ab ∈ I or c ∈ δ(I). After giving some basic properties of this new class of graded ideals, we generalize a number of results about 1-absorbing δ-primary ideals into these new graded structure. Finally, we study the graded 1-absorbing δ-primary ideals of the localization of graded rings and of the trivial graded ring extensions. [ABSTRACT FROM AUTHOR]

Background: Reducing malnutrition is a key priority for governments in low- and middle-income countries given its lasting effects on child development, health, income, and economic growth. Strategies to improve recommended infant and young child feeding (IYCF) practices, especially during the first two years of life, are considered among the most effective. Methods: In this paper, we evaluate the long-run impacts of an innovative education strategy based on interactive play and performing arts implemented in El Alto, Bolivia on caregivers' IYCF knowledge and practices. Two thousand and fifteen households were randomly assigned to intervention and control groups. Two rounds of data were collected approximately 30 and 42 months after baseline. We estimate short-term (30 month) and longer-term (42 month) intent-to-treat effects using multivariate linear regression analysis, with and without controlling for covariates. Results: The program significantly increased caregiver IYCF knowledge by 0.13 SDs in the short run, and this effect grew over time. The program also improved adherence to recommended IYCF practices by 0.23 standard deviations (SDs) in the short term, but the effect on practices dissipated over time, and no longer-term impacts were detected. Caregivers with above median baseline knowledge, number of children, and age appear to have benefited most from the program. Conclusions: Our findings suggest that entertainment-education interventions are a promising model for improving and maintaining IYCF knowledge. However, their ability to sustain more permanent changes in IYCF practices is less certain. Further evidence is needed to identify other avenues for producing long-term, sustainable behavior change, especially among indigenous populations in Latin America, where literature on education and behavior-change interventions related to IYCF practices is limited.

This paper provides pioneering estimates of the impact of loan-to-value (LTV) ratios, also known as leverage, on Bolivia's GDP. The empirical evidence reveals the pro-cyclicality between the economic and financial cycles, which affects the intertemporal resource allocation processes between the financial and real sectors. The findings from the RBC model demonstrate that shocks in the loan-to-value (LTV) ratios trigger a rise in housing prices and greater consumption by entrepreneurs, leading to an increase in investment, employment, and output. Additionally, the study confirms that LTV ratios can be a double-edged instrument, as excessive use can potentially destabilize the economy. [ABSTRACT FROM AUTHOR]

Considering the external effects of adjudicative activity of the Inter-American Court of Human Rights, structural questions emerge regarding the influence of IACtHR precedent in judicial branches of the Parties to the American Convention on Human Rights. In this sense, this paper seeks to apply the theoretical typologies developed by Ryan Goodman and Derek Jinks to the analysis of operative mechanisms of influence of international law inside the States' jurisdictions. In this regard, it was necessary to create new specific categories (eg, acculturative persuasive precedent, selective persuasive precedent), to test whether they suitably describe the application of Inter-American precedents, in an attempt to categorize the recent performance of the highest courts in Brazil, Colombia, Argentina, Chile, and Bolivia. Additionally, the concept of double control of conventionality has presented essential perspectives for the compliance with IACtHR judgments by demanding States, as well as the interpretation and application of national laws deemed compatible, or not, with the Pact of San José. In the end, quantitative analysis played an important role in measuring each national court's assimilation of international precedents as it outlined scenarios of explicit adoption of Inter-American Court precedent by national judicial branches. Sampled States were classified as follows: a) Brazil: selective persuasive IACtHR precedent with low performance; b) Colombia: acculturative persuasive IACtHR precedent with high performance; c) Argentina: selective persuasive IACtHR precedent with moderate performance; d) Chile: selective persuasive IACtHR precedent with high performance; and e) Bolivia: acculturative persuasive IACtHR precedent with moderate performance.

Purpose: This study aims to present a conceptual framework aimed at promoting educational innovation in supply chain management and logistics (SCM&L). The framework can help to design active learning experiences regarding student learning outcomes that tackle current challenges in the discipline. Emphasizing the significance of linking students' learning to real-world scenarios, the framework enables reflective learning through hands-on engagement in a constructive alignment, overcoming existing pedagogical limitations in the field. Design/methodology/approach: This study presents a qualitative research methodology that relies on the case study method. Three instances are presented to illustrate educational efforts of active learning in countries of Latin America, Bolivia, Mexico and Peru, linking real-world relevant situations to disciplinary teaching and learning. Findings: The innovative learning experiences introduced in this study transform real-world SCM&L operations into distinctive educational opportunities. These experiences facilitate learning not only within traditional classrooms but also in urban areas of the Latin American region, enabling students to interact with educational partners in authentic settings to achieve their intended learning outcomes. These experiences are characterized by their focus on establishing meaningful connections between learning and local communities, businesses or specific contexts. Research limitations/implications: The study recognizes various limitations of conceptual, methodological, execution-related and research process aspects. First, not all academics in the SCM&L discipline may universally acknowledge the importance of educational innovation and active learning experiences because of limited pedagogical awareness. Moreover, execution-related limitations arise from the demanding nature of incorporating active pedagogical approaches into courses, as they can be resource-intensive and time-consuming. Regarding research process limitations, the case study limits generalizability and broader inferences because of its particular views and locations, which require further investigation with other instances across other disciplines and geographical regions for validation. Practical implications: The practical implementation of this framework within the MIT SCALE network for Latin America and the Caribbean (LAC) demonstrates its potential in meeting diverse academic and institutional expectations and providing educational benefits to students. Social implications: The study makes a valuable contribution to prioritizing and coordinating pedagogical research by investigating the success of learning outcomes achieved through active and experiential implementations in various contexts. It provides inspiring examples of innovative learning experiences that can drive new developments not only within the LAC region but also in other areas, prompting a shift away from traditional educational approaches. Originality/value: This research presents a conceptual framework, which is developed from the insights obtained in the three learning experiences to guide future efforts in SCM&L education. The findings demonstrate how to structure active learning experiences based on authentic assessment and illustrate the potential for increased cooperation among institutions in Latin America. It also promotes the recognition of novel SCM&L active learning experiences and highlights some of the benefits of this approach. [ABSTRACT FROM AUTHOR]

The Silala is a small river, originating in the Andean Altiplano, which flows from Bolivia into Chile. Prior to a legal dispute between Chile and Bolivia over the status and use of the waters of the Silala, few hydrological studies had been performed in the basin. Further insights were required to better understand the surface‐water and groundwater discharges from Bolivia to Chile, and the effects of historical channelization of the Bolivian wetlands on these flows. A semi‐distributed hydrological model was therefore developed to estimate the discharges from the basin and provide recharge inputs to a groundwater model used to investigate the effects of channelization. Long‐term temperature and precipitation data were available for 1969–1992, while more detailed data were available for 2018–2019. 1969–1992 was selected as a suitable length of record for long‐term groundwater recharge estimation, and the recent data were reserved for model validation, reported in a companion paper. Prior model parameter ranges were identified based on field observations and scientific literature, and sampling of both input and parameter uncertainty allowed determination of representative, lower and upper groundwater recharge scenarios. Results show strong inter‐annual and seasonal variability, the largest groundwater recharge being observed during the Austral summer. A representative groundwater recharge rate of 39.5 mm/year was obtained for the basin to the international border, with feasible lower and upper bounds of 34.9 and 50.2 mm/year, respectively. This lies within the range of 21–51 mm/year estimated by Bolivia for 1969–2017, albeit higher than their best estimate (24 mm/year).

A key issue in the legal case before the International Court of Justice between Bolivia and Chile concerned artificial channels in the headwater wetlands of the Silala River in Bolivia, and their impact on the river and groundwater flow rates across the international border into Chile. In pleadings before the Court, Bolivia had claimed up to 40% changes in river flow, whereas Chile had maintained that these were much smaller. This paper reviews construction of a numerical groundwater model to quantify this impact, based on the hydrogeological conceptual model presented earlier in this volume. The groundwater model domain covers the Silala River topographical catchment, plus three adjacent closed (endorheic) topographical catchments to the northeast, which together form the groundwater catchment of the Silala River. The geometry was based on a 3D geological model, constructed based on knowledge gained from several geological mapping investigations. Surface water flows were simulated within a margin of error less than the range of uncertainty associated with the flow measurements. The resulting calibrated groundwater model was used to simulate scenarios corresponding to (a) the removal of channels in the Bolivian wetlands and (b) backfilling of the channels and a small increase in ground elevation (postulated by Bolivia due to long term peat accumulation). The results of these scenarios indicate that the measures would result in a small reduction to the surface water flow over the border to Chile; for Scenario A less than 1% change in surface flows, and for Scenario B less than 3%.

A dispute between Chile and Bolivia regarding the status and use of the waters of the Silala River resulted in proceedings before the International Court of Justice, initiated in 2016. The magnitude of the effect of historical channelization in Bolivia on surface water flows emerged as a major point of disagreement. Based on modeling by the Danish Hydraulic Institute (DHI), using the MIKE‐SHE and MIKE‐11 modeling systems, Bolivia suggested initially that the channels had increased surface flow by 30%–40% and later by 11%–33%. In the opinion of Chile's international experts, these effects would be small. This paper reviews the use of DHI's models by Bolivia and, subsequently, by Chile. Concerns about Bolivia's modeling raised by Chile included the selection of boundary conditions, inconsistent use of the two models for different scenarios, the use of inconsistent topographies for different scenarios, unexplained additions of water and numerical instabilities affecting the results. To investigate these discrepancies, additional simulations were performed by Chile. DHI's MIKE‐SHE and MIKE‐11 models were used for all scenarios, with consistent topography, spring and surface water flow representation. Numerical instabilities were reduced by adjustment of time steps and channel topography. These simulations showed that removing the channels reduces surface flow by a maximum of 3.5 L/s, or 2.4%. The sum of the groundwater and surface water outflow decreases by 2.6 L/s or 1.0%. This small decrease lies within the modeling error but is consistent with the expected effect of minor changes in evaporation.

The flows of surface water and groundwater from the Andes to the Atacama Desert are a vital source of freshwater, supporting ecosystems and human activities, but few substantive studies have addressed the hydrological and hydrogeological functioning of these systems. A dispute between Chile and Bolivia concerning the transboundary Silala River, recently heard before the International Court of Justice, The Hague, provided a unique opportunity for new scientific studies, reviewed in this Special Issue. First, findings from field studies that address the geological and geomorphological evolution of the Silala River basin and its current status, the key hydrological processes (including infiltration, actual evaporation from wetlands and alluvial plains, and surface water‐groundwater interactions), and the hydrogeological characterization of the major aquifers are reviewed. The dispute arose because Bolivia disagreed that the Silala was a transboundary river, subject to international law. As the Court proceedings evolved, this was accepted by Bolivia, but effects on surface flows of historical channelization in the Bolivian headwater wetlands remained a point of legal and technical disagreement. Bolivia asserted large increases in surface flow, based on modeling by their consultants, DHI. Chile held that these effects are small. In the second part of this paper, we summarize the modeling evidence. Chile's use of DHI's models, and its own hydrological and groundwater modeling of the basin, fully support Chile's position. We conclude with discussion of the Court's judgment, the challenges of physically‐based modeling of small changes in complex systems, and associated implications for judicial practice.

• The very first Argentine flags of Macha and Ayohuma share a common origin. • The original colour of both flags, blue, was achieved using the indigo dye. • It was determined that specifically, the dye used is indigotin, originating from Europe. Historical sources claim that the Argentine ensigns commonly referred to as Macha and Ayohuma flags have the same origin. The difference in their designs is remarkable, with the former being white, blue, and white in horizontal bands, while the latter has the coloured stripes at its ends. According to a historical account, these two flags were used by the patriot and creator of the Argentine flag, one of the parents of the homeland, Manuel Belgrano, when he first raised them on the banks of the Paraná River on February 27, 1812. Both flags were found by Father Martín Castro in 1883 behind a painting of Santa Cecilia in the church of Titiri near the town of Macha in Bolivia at an altitude of 4350 m above sea level. The composition of the Ayohuma flag was analysed in this paper, and the results were compared with those obtained and already published for the study conducted on the flag of Macha. It was determined by ATR-FTIR spectroscopy that the Ayohuma flag is made of silk, with the diameter of the individual silk filament of 12.5 μm, the dye used to colour the silk is indigotin, according to its resonance Raman spectrum, and methylene blue was detected by Surface-Enhanced Resonance Raman Spectroscopy, presumably utilized for the restoration of the coloured part of the flag.

Charcoal fragments preserved in soils or sediments are used by scientists to reconstruct fire histories and thereby improve our understanding of past vegetation dynamics and human-plant relationships. Unfortunately, most published methods for charcoal extraction and analysis are incompletely described and are therefore difficult to reproduce. To improve the standardization and replicability of soil charcoal analysis, as well as to facilitate accessibility for non-experts, we developed a detailed, step-by-step protocol to isolate charcoal from soil and to efficiently count and measure charcoal fragments. The extraction phase involves the chemical soaking and wet sieving of soils followed by the collection of macrocharcoal (≥500 μm). The analysis phase is performed semi-automatically using the open-source software ImageJ to count and measure the area, length, and width of fragments from light stereo microscope images by means of threshold segmentation. The protocol yields clean charcoal fragments, a set of charcoal images, and datasets containing total charcoal mass, number of fragments, and morphological measurements (area, length, and width) for each sample. We tested and validated the protocol on 339 soil samples from tropical savannas and forests in eastern lowland Bolivia. We hope that this protocol will be a valuable resource for scientists in a variety of fields who currently study, or wish to study, macroscopic charcoal in soils as a proxy for past fires.

Two isidiate species, Sticta arenosella and S. cellulosa, are reported from South America for the first time and the former species also as new to the Southern Hemisphere. Sticta arenosella was found in Chile and S. cellulosa in Bolivia. The identification of both species was confirmed by sequencing of the nuITS rDNA marker, a universal barcode of fungi, and the haplotype network analyses. Specimens of S. cellulosa possess sparse apothecia, which previously have not been observed in this species. [ABSTRACT FROM AUTHOR]

Can protests produce changes in electoral behavior? In this paper, we examine variations in voter turnout and electoral preferences at the local level after a protest cycle. Using data on protest occurrence during the 2019 social mobilizations in Chile and Bolivia and a difference-in-differences design, we assess the impact that street demonstrations had on voting behavior in the elections that took place the following year. We found that turnout was higher in municipalities that had protests, while the incumbent vote was lower. We argue that the effect on turnout is explained by the surge in political efficacy that emerged from the protests. Furthermore, we suggest that the protests enabled more effective blame attribution and heightened the salience of political issues, leading to changes in voter preferences. These results demonstrate the effect of protests on electoral dynamics, highlighting their role not only in mobilizing voters but also in shaping electoral preferences. [ABSTRACT FROM AUTHOR]

Water availability and quality are still challenges around the world, but access to safe drinking water is essential for human development. This study analyzed the chemical parameters of drinking water quality in the Santa Cruz de la Sierra region of Bolivia. Residual chlorine, pH and concentration of dissolved solids were measured in water supplied by drinking water and basic sanitation service providers (EPSA). The water quality results indicated that the water supplied met the requirements established by the Bolivian Standard NB 512 in terms of residual chlorine, pH and concentration of dissolved solids. However, a decrease in residual chlorine concentration was observed as the water moved away from the disinfection point. Microbiological testing is recommended to ensure the absence of viable organisms in the distributed water. In conclusion, this study highlights the importance of chlorination, as the only treatment performed in the study area, the pH and the concentration of dissolved solids as indicators of drinking water quality. Automation of chlorination processes and continuous monitoring of these parameters is suggested to ensure a safe and high-quality water supply in the study area. [ABSTRACT FROM AUTHOR]

In this study, we assess competing interpretations of a burnt ceremonial structure from the terminal Middle Formative period (ca. 300–100 BCE) by analyzing the stepped platform mound at Chiripa, Bolivia, through a systematic reconstruction of the fire that destroyed it. We developed a model of potential fire pathways, their social contexts, and material indicators. Our approach contrasts incipient fires from accident or arson to planned fires initiated for functional or social ends. We assessed these pathways for the Chiripa mound fire through experimental, geoarchaeological, faunal, and botanical data. Experiments were aimed at deducing the temperature, duration, and oxidation conditions of the fire. The fire temperature and duration were approximated from geoarchaeological analyses of construction materials in comparison with controls, and thermal alteration of faunal bone. Fuels were reconstructed through paleoethnobotanical analysis of charred remains from discrete areas within the burnt structure. We conclude that an intentional fire burned the structures on the Chiripa mound to temperatures of 700 °C or higher under oxidizing conditions for several hours. The pattern of heat-altered materials recovered would have required a substantial supplemental fuel load. At the 3840 masl elevation of Chiripa, the effective control of a high temperature oxidizing fire demonstrates technical expertise in fire management. Our findings indicate the fire appears intentional, likely a ritual event. We believe the structures were burned to facilitate a socio-political change during a period of social transition at the end of the Middle Formative period in Bolivia. [ABSTRACT FROM AUTHOR]

The Department of Beni, in the country of Bolivia, is thought to host a significant level of biodiversity as a result of its tropical, moist, and diverse climate and landscape. However, the biodiversity of Beni is also considered poorly known and understudied due to its inaccessible landscapes, socio-economic challenges, and an overall lack of biodiversity infrastructure. This emphasizes the need for comprehensive species inventories and the development of effective conservation policies and strategies. We conducted an assessment of biodiversity, environmental vulnerability, and conservation status of reptiles documented in Beni. We identified 169 reptile species, spanning three orders and twenty-five families that have been officially documented in Beni. Utilizing the Environmental Vulnerability Score (EVS), we classified these species into high (17.8%), medium (68.1%), and low (14.2%) vulnerability categories, while IUCN categorization revealed 1.8% of reptile species in Beni are classified as vulnerable and 0.6% as near threatened. We found significant differences in ecological drivers of vulnerability among species within all categories (high, medium, low), with habitat specificity and human persecution being significantly higher for high and medium-vulnerability species. Our results demonstrate the intricate vulnerabilities of Beni's reptiles, highlighting the need for comprehensive, species-specific conservation strategies and planning. Most importantly, our results offer a consolidated framework of information on reptile biodiversity and conservation for researchers, conservationists, and policymakers to use and build upon in the future that will facilitate the development of biodiversity infrastructure not only in the Department of Beni but throughout Bolivia and the Neotropics [ABSTRACT FROM AUTHOR]

This study investigates Bolivians' willingness to pay for an annual passport facilitating visits to protected areas (PAs) in Bolivia, aiming to address challenges in PA financing and management amidst escalating deforestation. Employing the contingent valuation method, a representative sample of citizens aged 18 or older from major cities across Bolivia participated in a telephone interviewing questionnaire. The findings reveal limited public awareness and recognition of PAs, alongside significant interest in visiting these areas for tourism purposes or simply donating to the system to reduce its current financial gaps. Concerns regarding trust and transparency in fund management are highlighted, with demographic factors and perceptions influencing willingness to pay estimated at approximately USD 35 for a one-year passport. This study underscores the necessity for targeted interventions to enhance public awareness, improve infrastructure, and ensure transparency in fund management, thereby promoting sustainable tourism and safeguarding Bolivia's PAs.

Discourses on sustainable development seldom question the mode of production behind so-called green technologies. Yet so long as these technologies are developed under a capitalist framework, they too will necessitate the cheapening of nature and labor. The socio-ecological costs of development in the Global North have long been borne by the Global South, and the production of green technologies risks reproducing this pattern. To critically engage with these dynamics, we use a political ecology framework to analyze lithium extraction in Bolivia. Supported by interviews with experts on Bolivian lithium extraction, we consider: (1) the anticipated socio-ecological impacts of lithium extraction; (2) the political economy of contemporary Bolivia; and (3) the governance/politics of lithium extraction at the local and global levels. The Bolivian state's effort to exercise its sovereignty and develop its economy through "100% state-led lithium industrialization" risks re-inscribing Bolivia's subordinate position in the world-system. Given the anticipated ecological impacts and unequal revenue distribution, local communities may be on the verge of accumulation by dispossession. [ABSTRACT FROM AUTHOR]

The impacts of the accelerated glacier retreat in recent decades on glacier runoff changes are still unknown in most Andean catchments, increasing uncertainties in estimating water availability. This particularly affects the outer tropics and Dry Andes, heavily impacted by prolonged droughts. Current global estimates overlook climatic and morphometric disparities, which significantly influence model parameters, among Andean glaciers. Meanwhile, local studies have used different approaches to estimate glacier runoff in a few catchments. Improving 21st-century glacier runoff projections relies on calibrating and validating models using corrected historical climate inputs and calibrated parameters across diverse glaciological zones. Here, we simulate glacier evolution and related runoff changes between the periods 2000–2009 and 2010–2019 across 786 Andean catchments (11 282 km2 of glacierized area, 11° N to 55° S) using the Open Global Glacier Model (OGGM). TerraClimate atmospheric variables were corrected using in situ data, getting a mean temperature bias by up to 2.1 °C and enhanced monthly precipitation. Glacier mass balance and volume were calibrated, where melt factor and the Glen A parameter exhibited significant alignment with varying environmental conditions. Simulation outcomes were validated against in situ data in three documented catchments (with a glacierized area > 8 %) and monitored glaciers. Our results at the Andes scale reveal an average reduction of 8.3 % in glacier volume and a decrease of 2.2 % in surface area between the periods 2000–2009 and 2010–2019. Comparing these two periods, glacier and climate variations have led to a 12 % increase in mean annual glacier melt (86.5 m3s-1) and a decrease in rainfall on glaciers of - 2 % (- 7.6 m3s-1) across the Andes, with both variables comprising the glacier runoff. We confirmed the utility of our corrected regional simulations of glacier runoff contribution at the catchment scale, where our estimations align with previous studies (e.g., Maipo 34° S, Chile) as well as provide new insights on the seasonal glaciers' largest contribution (e.g., La Paz 16° S, Bolivia) and new estimates of glacier runoff contribution (e.g., Baker 47° S, Chile).

The restorative nature of Aymara Indigenous justice in Bolivia: Much current Western scholarship suggests that the modern idea of restorative justice is not totally a recent invention; it shares a common basis with and is similar to Indigenous justice. This article draws on fieldwork concerning Indigenous justice in Bolivia and contends that it has little in common with restorative justice. In much of the Western world, modern justice systems are largely retributive, based on individual blame and punishment, and restorative mechanisms are used rarely as complementary. Our Bolivian fieldwork revealed Indigenous justice to be a full-fledged, intrinsically restorative system of justice. This article will briefly set out conceptualisations and practices of restorative justice in the Western world before going on to consider in some detail the Indigenous system in Bolivia. It will contend that it is the differences between Western restorative justice and Indigenous justice which are more important to a proper understanding of Indigenous justice. It will make the argument that linking the two may be damaging to the comprehension and survival of Indigenous justice and may also inhibit the real potential of Indigenous justice to enrich justice practices in Western countries.

Four species of the genus Sticta are described as new from Bolivia, based on morphological examination and phylogenetic analysis of the fungal ITS barcoding marker. Additionally, two species are reported as new to Bolivia (their identification confirmed by molecular data) and one previously reported species is confirmed by molecular data for the first time. Detailed morphological and anatomical descriptions are provided for all new species. Two of the new species, S. isidiolobulata Ossowska, B. Moncada, Lücking & Kukwa and S. madidiensis Ossowska, B. Moncada, Lücking & Kukwa belong to clade I, as defined in previous studies. In contrast, S. montepunkuensis Ossowska, B. Moncada, Lücking & Kukwa and S. macrolobata Ossowska, B. Moncada, Lücking & Kukwa, also described here as new to science, belong to clade III. Sticta isidiolobulata has an irregular to suborbicular thallus of medium size, with isidia developing into spathulate lobules, cyanobacterial photobiont and apothecia with entire to weakly-crenate margins. The large irregular thallus of the cyanobacteria-associated S. macrolobata has broad lobes, apothecia with verrucous to tomentose margins and cyphellae with raised margins, whereas S. madidiensis has a medium-sized, palmate to irregular thallus with a stipe, but without vegetative propagules and apothecia. Sticta montepunkuensis has large and irregular thalli with green algae as photobiont, apothecia with crenate to verrucous margins and urceolate cyphellae with a wide pore and a scabrid basal membrane. Two species, S. beauvoisii Delise and S. riparia Merc.-Díaz are reported as new to Bolivia (the latter also as new to South America) and belong to clade III. Sticta tomentosa (Sw.) Ach., species confirmed from Bolivia by molecular data, belongs to clade II. Sticta beauvoisii is characterised by a smooth yellowish-brown upper surface with darker apices and abundant, marginal isidia and a brown lower surface with golden-chocolate brown primary tomentum and sparse, golden-brown rhizines. Sticta riparia has a strongly branched thallus, with undulate lobes and abundant, marginal, palmate, grey to dark brown phyllidia and greyish-brown lower surface with the primary tomentum absent towards the margins. Sticta tomentosa has palmate, bluish thalli with white cilia and abundant, submarginal apothecia and creamy-white lower surface with a sparse, white primary tomentum. [ABSTRACT FROM AUTHOR]

Purpose: This study compared approaches to school closures in four Latin American countries (Bolivia, Colombia, Ecuador, Peru), describing the impact on the health and educational wellbeing of school-age children and youth, and evaluating their approaches in regard to continuing education through the pandemic. Design/methodology/approach: We collected 75 publicly available documents including scientific and gray literature (government documents and news releases), that referred to school closures and their impact on children's health and wellbeing. We did thematic analyses using open, axial, and selective coding and applied the latest Health Promoting Schools standards and indicators to the findings. Findings: Results showed that countries followed epidemiological reasons for prioritizing school closures while adopting some policies that abide by Health Promoting School principles. While they emphasized the need to reopen schools so that instruction could continue, school closures were among the longest in the world. The most significant impacts on wellbeing identified in the four countries were related to food security and mental health. Research limitations/implications: This study focused on a particular set of documents, and it may not capture the full spectrum of relevant information in different contexts or regions. Practical implications: By comparing school closures approaches among four Latin American countries, this study highlights the importance of context-specific interventions. In a post-pandemic era, lessons learned from these experiences should help foster more resilient and inclusive educational systems and explore the paths forward for following the new Health Promoting Schools framework in the region. Originality/value: Cross-country qualitative analyses on this topic are rare. This study adds to the knowledge base by eliciting lessons for future health education research and policy efforts.

The present study examined how conspiracy beliefs about COVID-19 vaccines specifically relate to symptoms of fear of COVID-19 in a sample of four South American countries. A total of 1785 people from Bolivia, Colombia, Ecuador, and Peru participated, responding to a sociodemographic survey, the Fear of COVID-19 scale (FCV-19 S) and the Vaccine Conspiracy Beliefs Scale-COVID-19 (VCBS-COVID-19). Network analysis identified the most important symptoms of fear and conspiracy beliefs about COVID-19 vaccines (nodes) and the associations between them (edges). In addition, the robustness of the network of these indicators of centrality and the possible differences in the structure and connectivity of the networks between the four countries were evaluated. The results suggest that the nodes with the highest centrality were items 2 and 5 of the FCV-19 S and item 2 of the VCBS-COVID-19. Likewise, item 6 is the belief that most predicts conspiracy beliefs about vaccines against COVID-19; while item 6 was the symptom that most predicts fear of COVID-19. The findings strongly support cross-cultural similarities in the networks across the four countries rather than differences. Although it was expected that a higher presence of symptoms of fear of COVID-19 may lead people to compensate for their fear by believing in conspiratorial ideas about vaccines and, consequently, rejecting the COVID-19 vaccine, the results do not clearly show this relationship. This could lead other researchers to generate evidence to explain the differences between Latin American countries and countries in other contexts in terms of vaccination rates. This evidence could be useful to develop policies favoring vaccination against COVID-19 that are more contextualized to the Latin American region, characterized by social instability and economic recession during the pandemic.

Climate change (CC) impacts on hydrology pose significant global concerns due to their effects on water availability, thereby impacting various human activities reliant on this essential resource. This study assesses the influence of CC on the water supply in the Angostura-Bolivia basin. We employed the RegCM4 system, which develops its own regional climate models (RCMs) tailored to the Angostura basin using specific convective schemes, diverging from reliance on pre-existing RCMs, like those provided by CORDEX. Methodologically, the study involves hydrometeorological data collection and analysis, utilizing dynamic and statistical downscaling methods to refine the RCMs derived from ERA-Interim reanalysis data. Subsequently, precipitation and temperature projections are generated under CC scenarios (RCP 4.5 and RCP 8.5) for both near (2045–2055) and far (2065–2075) future periods, compared to the historical period (1981–2010). The final stage employs the HydroBID system to project future runoff, considering both perturbed and unperturbed hydrometeorological data under CC effects. The analysis of flow duration curves for 50%, 75%, and 90% exceedance probabilities reveals a significant reduction in flows across all scenarios, indicating a noteworthy impact on water availability. These findings underscore the urgency of comprehending and adapting to CC on hydrology, emphasizing the critical importance of sustainable water resource management amidst evolving climatic conditions.

Most developing countries fail to provide waste collection services to all their citizens, which leads to many adverse effects. Nevertheless, research has not yet succeeded in explaining the underlying causes. We drew up a quantitative system dynamics model that can be used to diagnose the complex societal system that is leading to poor waste collection. The model describes demographic, social, economic, financial, participatory, and governance processes that may play a role. It is calibrated against real-life datasets for six Latin American countries. The calibration shows adequate performance of the model. Strong population growth appears to have a dual effect. It leads to an increase in available budgets for collection but also tends to dilute the available budget per inhabitant. Processes on the growth of GDP, government revenues, and quality of governance strongly improve access of citizens to waste collection. They do so separately but also because they reinforce each other. But, there are differences per country. Progress in Belize seems to be hampered mostly by low governance quality. For Bolivia, the hurdle seems to consist of an inability to increase public revenues and absorb new urban citizens. Ecuador and Paraguay would also benefit from increased revenues along with an ability to increase public participation. The Dominican Republic and Panama reveal an overall passivity to improve their services. This model may be useful for decision makers globally to develop effective interventions.

The South American central Andes have a great richness of Asteraceae, where the genus Stevia (Eupatorieae, Piqueriinae) is also especially diverse. The taxonomy of Stevia species in the southern part of the central Andes pose a challenge because of the unclear delimitation among the species and overlap of morphological characters. Two species complexes were identified for the region comprising north Argentina and southern Bolivia. In this study, our objectives were to employ morphometric analyses to assess the delimitation of taxa within the Stevia alpina Griseb. and Stevia chamaedrys Griseb. complexes. We aimed to identify informative morphological characters and gain insight into the identity of species in each group. To accomplish this, we utilised cluster analysis, principal-component analysis, non-metric multidimensional scaling and univariate analyses to evaluate 37 morphological traits. In total, 200 specimens were examined, covering the entire geographic distribution of each species complex. We found support for the recognition of nine species: Stevia alpina, S. breviaristata Hook. & Arn., S. chamaedrys, S. mandonii Sch. Bip., S. mercedensis Hieron., S. minor Griseb., S. potrerensis Hieron., S. procumbens Hieron. and S. vaga Griseb. A new combination and status is proposed for S. tarijensis Hieron., incorporating it as a variety of S. mandonii, and S. centinelae Cabrera and S. crassicephala Cabrera are merged as synonyms under the name S. alpina. Two neotypes are designated for the names S. mercedensis and S. potrerensis. [ABSTRACT FROM AUTHOR]

This article addresses the results of an ethnography study on the cross-border experiences of Bolivian Aymara women in the Chilean territories of the Andean Triple-border (between Chile, Peru, and Bolivia). Its objective is to test the assumptions of the international literature on the relationship between gender inequalities, care, and migration. Its analytical focus is on the relationship between (1) the constitution of inequalities in the gender division of labor in the women's families and ethnic communities, (2) their productive and reproductive overloads, and (3) the articulation of female care chains that sustain cross-border mobilities.

By paying attention to what Peruvian and Bolivian students in schools say about how they are seen and treated by their nativeborn peers, this article aims to analyze the ways in which symbolic boundaries are produced, eventually giving way to social boundaries between natives and migrants. The methodology is based on in-depth interviews with students, parents, and educators of rural and urban schools in the region of Arica y Parinacota, the northernmost region of Chile, by the borders with Peru and Bolivia. We conclude that the production of symbolic boundaries among students emerges as discourses about nationality, skin color, ethnicity, and history. Peruvian and Bolivian migrant students describe being teased by their native-born peers because of their country of origin, for being darker-skinned, for being Aymara, and for having lost the War of the Pacific (and, in the case of Bolivians, for having lost access to the coastline). Some migrant students perceive these discourses as discrimination and consider them harmful; however, many others accept them as normal school stuff--as long as there is no physical violence. Moreover, teachers and parents do not see these interactions as problematic. The article concludes that the normalization of stigmatizing and discriminatory dynamics against migrant students complicates their inclusion in Chilean schools. [ABSTRACT FROM AUTHOR]

This paper uses a unique data set and a natural experiment to test if electoral fraud can exist in late-arriving votes. On the night of the 2019 Bolivian elections, the official vote counting system that was expected to publish the results real-time, suddenly stopped. When it resumed, the results had flipped. We estimate several difference-in-differences specifications using a 2016 referendum and the votes of other political parties. We find that the extent of the fraud is 2.51% of the valid votes, sufficient to change the outcome of the election. Our results are robust to polling-station-level shocks common across 2019 and 2016, as well as 2019 specific shocks. This controls for geography, socioeconomic characteristics, unobserved voting preferences, and endogeneity in the arrival of the polling station results. We report evidence of fraud that occurred before the shutdown and document a statistically significant discontinuous jump in the votes during the shutdown. We provide insights on how to apply our different identification strategies to test for fraud in other elections. • Use a unique data set to test for and find electoral fraud in late-arriving votes. • Have various difference-in-differences specifications using a referendum and the votes of other political parties. • We control for geography, socio-economic characteristics, and unobserved voting preferences. • There is a statistically significant discontinuous jump in the votes during the shutdown. • We provide insights on how to apply these fraud identification methods in other elections.

• Indigenous autonomy has multiple meanings in tension for TIPNIS residents. • Relations between indigenous autonomy and environmental conservation are complex. • Age and community belonging are relevant in shaping indigenous autonomy priorities. • Intercommunal/intergenerational dialogues on material bases of autonomy are needed. • The Q-method is useful to elucidate heterogeneity in indigenous autonomy conceptions. State-recognized indigenous autonomy regimes have been one of the main avenues by which various Latin American countries, including Bolivia, have recently advanced indigenous rights. However, implementation of pluralistic political organization is slow and challenging. As States engage in supporting the increase of extractive activities, including in indigenous territories, tensions between local and national interests crystallize in struggles for territorial control which unavoidably focus on who gets to decide what autonomy or territory mean. Centering on the case of the Isiboro Sécure Indigenous Territory and National Park (TIPNIS), this paper aims to contribute to the understanding of autonomy conceptions among indigenous people, particularly in relation to natural resource governance. Through semi-structured interviews and a Q-sorting test, I investigated preferences allocated to multiple and sometimes conflicting autonomy meanings by residents of the TIPNIS – a site of contention that has fueled debates around development pathways and indigeneity in Bolivia. Findings highlight the foreign nature of the term "indigenous autonomy", the relevance of natural resource governance within autonomy conceptions, and the heterogeneity of priorities in understanding indigenous autonomy depending on socio-spatial and generational factors. Building on debates in political geography, these findings illustrate both sensible pragmatism and tensions in approaching indigenous autonomy, as well as implications for fostering dialogues across communities and generations. This study supports the argument that indigenous autonomy should be understood as multidimensional, territorially-specific, relational, and dynamic. It also contributes to complexifying relations between indigenous autonomy and environmental conservation, which appear as heterogenous and fluid, challenging essentialist views.

Background: Cervical cancer is a major health problem in Latin America. In 2019, the Italian Agency for Development Cooperation (La Paz regional site) conducted a pilot study to estimate the prevalence of high-risk human papillomavirus (HPV) and the feasibility of HPV screening in Bolivia through self-sampling and portable and transportable laboratory instruments for HPV testing in urban and rural areas. Methods: Women aged 20–65 years from La Paz (urban area), Toro Toro (rural area), and Acasio (rural area) were enrolled in local public health centers between Dec 1, 2019, and June 30, 2021. Self-sampling was carried out with the Viba-Brush system (Rovers, Oss, Netherlands) and samples were preserved in ThinPrep containers (Hologic Corporation, San Diego, CA, USA). The GeneXpert system (Cepheid, Sunnyvale, CA, USA) for high-risk HPV testing detects HPV E6 and E7 DNA via real-time PCR in a mobile system of easy execution requiring minimal manual intervention. The system provides results in about 1 h. The hr- HPV prevalence data, overall and partial genotyping, were analyzed considering the following age groups: 20–34, 35–44, and 45–65 years old. Findings: 2168 women were enrolled: 614 (28.3%) in La Paz, 743 (34.3%) in Toro Toro, and 811 (37.4%) in Acasio. Only one sample was collected from each participant. 2043 (94.2%) of 2168 samples were adequate for HPV testing. 255 (12.5%) samples were positive for high-risk HPV. Comparing the urban area (La Paz) versus rural combined areas (Acasio+Toro Toro), using a logistic model, the HPV total rate was statistically significantly higher in the city of La Paz (15.0% vs 11.4%; OR:1.37;95% CI: 1.04–1.80). Furthermore, the HPV prevalence was declining by age, and the urban/rural odds ratio was 1.50; (95% IC 1.13–19). The overall HPV 16 positivity was 2.7% (55/2043) and for HPV 18/45 was 1.8% (37/2043) without any statistically significant differences between the three BHU enrolling centers. Only the prevalence of HPV group '39/56/66/68' was significantly higher in La Paz (p<0,001) in comparison to Acasio and Toro Toro. Interpretation: The total and age-adjusted prevalence of high-risk HPV infection in rural and urban areas in Bolivia, as measured with a validated test for screening, is similar to that observed in Europe and the USA. Our study shows that a screening protocol for HPV testing with self-sampling would be feasible in urban and rural areas in Bolivia, and that the reported high occurrence of cervical cancer in Bolivia is not related to a higher rate of high-risk HPV infections. Carrying out HPV tests locally avoids the issues associated with transportation and storage of the collected material and allows the participant to wait in the clinic for the test result, overcoming the very long response time for screening test in Bolivia.

Introduction: Disruptive uncertain events often necessitate universities to abruptly shift from face-to-face to remote online learning, posing challenges to instructional quality and learning outcomes. Remote online instruction may lack social interaction, educational resources, and practical activities, hindering effective learning. Methods: This study presents an experiential learning framework designed to foster active learning experiences amidst disruptive uncertain events. The framework incorporates such events as study situations to enhance student motivation and engagement. A methodology for designing learning experiences is proposed, with a focus on incorporating real-world disruptions into educational settings. Results: A case study is presented, detailing the implementation of the framework in supply chain management and logistics education at a private university in Bolivia, amidst the COVID-19 pandemic. Results indicate that the novel learning experience positively impacted student motivation and engagement, facilitating the achievement of learning outcomes. Discussion: The initial implementation suggests that the novel learning experience positively impacted student motivation and engagement while achieving their intended learning outcomes. However, further instances of utilizing the proposed framework are necessary to ascertain its generalizability and effectiveness across diverse contexts and situations. Identifying similarities or invariances will help validate the applicability of this approach in different educational settings affected by disruptive uncertain events. [ABSTRACT FROM AUTHOR]
