- Abstract
Public spending on education has increased significantly in Latin America over the last several decades. Yet, the question remains as to whether greater spending translates into a more equitable distribution of resources. We address this issue by measuring inequality in per-pupil spending between regions of varying socioeconomic status (SES) within five different countries: Brazil, Chile, Colombia, Ecuador, and Peru. The results show that while Brazil's funding gap has narrowed over time, this federal nation has the widest socioeconomic spending divide, due to large inequalities in local revenues between high and low SES regions. School funding in Colombia has become more regressive over time, though its gap is half the size of Brazil's. Meanwhile, the distribution of school funding in Peru has changed, shifting from regressive (benefiting the richest regions) to progressive (benefiting the poorest regions). Education spending in Chile and in Ecuador have instead been consistently progressive. However, while the progressiveness of funding in Ecuador is driven by transfers targeting disadvantaged rural areas, the funding formulas in Chile address socioeconomic inequalities beyond the rural-urban gap.

- Abstract
In the past decade, hundreds of impact evaluation studies have measured the learning outcomes of education interventions in developing countries. The impact magnitudes are often reported in terms of "standard deviations," making them difficult to communicate to policy makers beyond education specialists. This paper proposes two approaches to demonstrate the effectiveness of learning interventions, one in "equivalent years of schooling" and another in the net present value of potential increased lifetime earnings. The results show that in a sample of low- and middle-income countries, one standard deviation gain in literacy skill is associated with between 4.7 and 6.8 additional years of schooling, depending on the estimation method. In other words, over the course of a business-as-usual school year, students learn between 0.15 and 0.21 standard deviation of literacy ability. Using that metric to translate the impact of interventions, a median structured pedagogy intervention increases learning by the equivalent of between 0.6 and 0.9 year of business-as-usual schooling. The results further show that even modest gains in standard deviations of learning--if sustained over time--may have sizeable impacts on individual earnings and poverty reduction, and that conversion into a non-education metric should help policy makers and non-specialists better understand the potential benefits of increased learning.

- Abstract
This paper examines common instructional strategies in early grade mathematics interventions through a review of studies in classrooms in low- and middle-income countries. Twenty-four studies met the criteria for inclusion, and analyses reveal four sets of instructional strategies for which there is evidence from multiple contexts. Of the 24 studies, 16 involved the use of multiple representations, 10 involved the use of developmental progressions, 6 included supporting student use of explanation and justification, and 5 included integration of informal mathematics. Based on the review, we provide conclusions and recommendations for future research and policy.

- Abstract
Good teachers are essential for high-quality educational systems. However, little is known about teachers' skills formation during college. By combining two standardized tests for Colombian students, one taken at the end of senior year in high school and the other when students are near graduation from college, this paper documents the extent to which education majors relatively improve or deteriorate their skills in quantitative reasoning, native language, and foreign language, in comparison to students in other programs. Teachers' skills vis-à-vis those in other majors deteriorate in quantitative reasoning and foreign language, although they deteriorate less for those in math-oriented and foreign language oriented programs. For native language, there is no evidence of robust differences in relative learning mobility. An appendix contains Figure A1 and Tables A1 and A2.

- Abstract
This paper examines the impact of Colombia's Programa de Ampliacion de Cobertura de la Educacion Secundaria (PACES), which provided over 125,000 poor students with private secondary school vouchers, many of which were awarded by lottery. Researchers surveyed lottery winners and losers to compare educational and other outcomes. Results showed no significant enrollment differences between winners and losers 3 years after application, with most students in both groups still in school. Lottery winners were 15 percentage points more likely to attend private than public schools. They had completed an additional .1 years of school and were 10 percentage points more likely to have completed 8th grade, primarily because they repeated fewer grades. Winners scored .2 standard deviations higher on standardized tests. PACES did not affect dropout rates significantly. Lottery winners were less likely to be married and cohabiting and worked about 1.2 fewer hours per week than losers. They increased their educational expenditure by about 70 percent of the value of the voucher. The voucher program increased annual government educational expenditure by $24 per winner, but costs were probably much less than increases in the winners' earnings due to greater educational attainment.

8. Can You Hear Me? The Right of Young Children to Participate in Decisions Affecting Them. Working Papers in Early Childhood Development, No. 36

- Abstract
"Can You Hear Me? The Right of Young Children to Participate in Decisions Affecting Them" emphasises that participation enhances children's self-esteem and confidence, promotes their overall capacities, produces better outcomes, strengthens understanding of and commitment to democratic processes and protects children more effectively. Participation provides the opportunity for developing a sense of autonomy, independence, heightened social competence and resilience. The benefits are therefore significant, and adults with both direct and indirect responsibility for children need to acquire a greater humility in recognising that they have a great deal to learn from children. But the case for listening to young children goes beyond the beneficial outcomes. It is also a matter of social injustice and human rights. All people, however young, are entitled to be participants in their own lives, to influence what happens to them, to be involved in creating their own environments, to exercise choices and to have their views respected and valued.

- Abstract
This monograph summarizes the results of a World Bank research project that compared private and public secondary school costs and achievement in five developing countries--Columbia, the Dominican Republic, the Philippines, Tanzania, and Thailand. All the case studies address the question: Would a high school student, selected at random from the general student population, perform better in a public or private school? In the absence of experimental data, the studies compare students' performance on standardized tests in a cross-section of public and private schools. Student background, motivation, innate ability, and prior performance are controlled through the use of various statistical techniques. The report also compares the costs of public and private schools. The principal findings include: (1) although students in private schools come from more privileged families than those in public schools, on average, there is a significant overlap between the two groups; (2) with student background and selection bias held constant, students in private schools out-perform students in public schools on a variety of achievement tests; (3) unit costs of private schools are lower than those of public schools; and (4) private schools are organized for greater school-level decision making and emphasis on enhancing student achievement; this seems to affect the mix of inputs that private versus public schools choose. Implications for policy include: (1) over-restrictive regulations on private schools may be suppressing an efficient way to provide education; (2) in some cases, governments could encourage greater private sector participation in education; and (3) public schools could emulate at least some of the teaching and administrative practices of their private counterparts.

- Abstract
This combination report/guide summarizes practical "how-to" information on the development and operation of national training boards that was gathered in a series of case studies of the effectiveness of national training boards in Canada, Singapore, Sweden, and the United Kingdom and in studies of training boards in Australia, Brazil, Colombia, Germany, and South Africa. The introductory chapter describes the research on which the guide is based, discusses common themes affecting the quality of training in the countries studied, and examines the rationale for training programs. Chapter 2 summarizes the subsequent discussion of the effectiveness of national training boards in the form of a checklist and guidelines for use by countries considering establishing a national training board. Chapters 3-9 synthesize research findings into practical recommendations dealing with the following aspects of initiating and operating national training boards: enabling legislation, training board composition, training board structure, financial resources, delivery of training, institutional planning and operations, and testing and certification. Chapters 10 and 11, which are more analytical than the chapters preceding them, examine the perception and images of national training boards and lessons learned from the case studies.

The SIR Iber highlights the geographical location of Ibero-American universities by positioning them according to the indicators grouped into three main factors: research, innovation and social impact. The 2020 edition highlights the formation of three groups of countries according to the production capacity of higher education institutions. In group 1 we have: Brazil, Mexico, Chile, Argentina, and Colombia as Latin American countries that managed to publish more than 60,000 papers in the period 2014-2018. This paper analyzes and compares the indicators from the five (05) Latin American countries in group 1 of the SIR Iber 2020 referring to investment in I+S as a percentage of its Gross Domestic Product (PIB), the number of full-time equivalent researchers (Inv JCE), the production (%) of scientific works in the university education sector, to name a few. A conglomerate formed with the Normalized Impact (NI) of public and private IESs is presented, regarding the global average of citation, with the data published in the SIR IBER 2020 Report, and highlights that Chile has a normalized impact above the World average for both public and private IES publications.

- Abstract
Fiscal constraints have limited education budgets in developing countries. Increases necessary to expand access to highly subsidized and publicly provided education have not been forthcoming. Another concern is that education is being inadequately and inefficiently provided by the public sector. This study is an inquiry into the nature of the achievement differential between public and private schools in Colombia and Tanzania. It questions the extent to which the differential in academic achievement can be attributed to student characteristics rather than school inputs, attempts to estimate the quality differences between the public and private secondary schools in these two countries, as measured by student performance on the achievement tests (ACATESTs). Estimated sample-selection effects suggest that Colombian students sort themselves by type of institution, public or private; but Tanzanian students are selected by a hierarchical mechanism, with the lowest-scoring students entering private institutions. These effects are consistent with the different institutional frameworks for educational choice in these two countries. For each country, however, private schools offer an achievement advantage. By standardizing for differences in student and school attributes, private school students have higher achievement test scores. (Author/NL)

- Abstract
Mold deterioration of historical documents in archives and libraries is a frequent and complex phenomenon that may have important economic and cultural consequences. In addition, exposure to toxic fungal metabolites might produce health problems. In this work, samples of broths of fungal species isolated from the documentary material and from indoor environmental samples of the Archive of Bogotá have been analyzed to investigate the presence of mycotoxins. High resolution mass spectrometry made possible to search for a large number of mycotoxins, even without reference standards available at the laboratory. For this purpose, a screening strategy based on ultra-high pressure liquid chromatography coupled to quadrupole-time of flight mass spectrometry (UHPLC-QTOF MS) under MS(E) mode was applied. A customized home-made database containing elemental composition for around 600 mycotoxins was compiled. The presence of the (de)protonated molecule measured at its accurate mass was evaluated in the samples. When a peak was detected, collision induced dissociation fragments and characteristic isotopic ions were also evaluated and used for tentative identification, based on structure compatibility and comparison with literature data (if existing). Up to 44 mycotoxins were tentatively identified by UHPLC-QTOF MS. 34 of these tentative compounds were confirmed by subsequent analysis using a targeted LC-MS/MS method, supporting the strong potential of QTOF MS for identification/elucidation purposes. The presence of mycotoxins in these samples might help to reinforce safety measures for researchers and staff who work on reception, restoration and conservation of archival material, not only at the Archive of Bogotá but worldwide., (Copyright © 2015 Elsevier Inc.

The success of a scientist depends on their production of scientific papers and the impact factor of the journal in which they publish. Because most major scientific journals are published in English, success is related to publishing in this language. Currently, 98% of publications in science are written in English, including researchers from English as a Foreign Language (EFL) countries. Colombia is among the countries with the lowest English proficiency in the world. Thus, understanding the disadvantages that Colombians face in publishing is crucial to reducing global inequality in science. This paper quantifies the disadvantages that result from the language hegemony in scientific publishing by examining the additional costs that communicating in English creates in the production of articles. It was identified that more than 90% of the scientific articles published by Colombian researchers are in English, and that publishing in a second language creates additional financial costs to Colombian doctoral students and results in problems with reading comprehension, writing ease and time, and anxiety. Rejection or revision of their articles because of the English grammar was reported by 43.5% of the doctoral students, and 33% elected not to attend international conferences and meetings due to the mandatory use of English in oral presentations. Finally, among the translation/editing services reviewed, the cost per article is between one-quarter and one-half of a doctoral monthly salary in Colombia. Of particular note, we identified a positive correlation between English proficiency and higher socioeconomic origin of the researcher. Overall, this study exhibits the negative consequences of hegemony of English that preserves the global gap in science. Although having a common language is important for science communication, generating multilinguistic alternatives would promote diversity while conserving a communication channel. Such an effort should come from different actors and should not fall solely on EFL researchers. [ABSTRACT FROM AUTHOR]

Purpose: This paper aims to identify complementary strategies for urban freight logistics in a low emission zone (LEZ) that can be implemented in downtown Medellin, Colombia. The strategies will be executed by identifying the characteristics and problems of the business establishments in the area and the entrepreneurs’ opinions. Design/methodology/approach: First, a literature review is performed to identify global and complementary strategies for the future LEZ, which is the study subject. Then, a “pilot” zone (a main corridor) of downtown Medellín is selected, and the business establishments of the area are identified to spot problems and evaluate possible strategies for the future LEZ. This identification and evaluation phase is conducted by interviewing logistics managers in 105 establishments selected in the corridor for analysis. Findings: One of the outstanding findings concerns the specificity of the logistics and mobility problems in downtown Medellin, located in Colombia, a developing country. The main issues are traffic congestion, lack of regulation and control in loading and unloading areas, as well as inadequate infrastructure for these operations. These obstacles significantly impact business activities and air quality in the area. The proposed solutions to complement the LEZ strategy for freight transport focus on improving regulation, establishing specific loading and unloading areas, exploring sustainable transportation options such as the cargo bike, and supporting small and medium-sized businesses. This emphasizes the situation’s complexity and the need for a comprehensive approach to address these logistical and environmental challenges. Originality/value: This study analyses urban freight logistics strategies that complement the traffic flow restriction policies imposed by low-emission zones. Unlike other studies that address these two issues independently, this paper specifically examines how to improve a LEZ as a comprehensive strategy to reduce the environmental impact of freight transport. In addition, it is noted that most publications tend to focus on passenger mobility strategies, which highlights the potential for research in the freight logistics field. [ABSTRACT FROM AUTHOR]

This volume contains papers submitted to the 10th Annual Conference of the Bulgarian Comparative Education Society, held in Kyustendil, Bulgaria, 12-15 June 2012. The overall goal of the 10th BCES conference is to facilitate discussion of different perspectives on international education providing a forum for scientific debate and constructive interaction in a multi cultural social environment such as Bulgaria. This is a jubilee conference. Ten might not mean too much for large scholarly societies in other countries, especially in the Western world. However, for a small society like BCES, ten means a lot. It means trust, international recognition, constant interest, well-developed academic cooperation, and the most important--it means an established conference tradition.

- Abstract
Background: Real-time PCR is a sensitive and specific method for the analysis of Plasmodium DNA. However, prior purification of genomic DNA from blood is necessary since PCR inhibitors and quenching of fluorophores from blood prevent efficient amplification and detection of PCR products., Methods: Reagents designed to specifically overcome PCR inhibition and quenching of fluorescence were evaluated for real-time PCR amplification of Plasmodium DNA directly from blood. Whole blood from clinical samples and dried blood spots collected in the field in Colombia were tested., Results: Amplification and fluorescence detection by real-time PCR were optimal with 40× SYBR® Green dye and 5% blood volume in the PCR reaction. Plasmodium DNA was detected directly from both whole blood and dried blood spots from clinical samples. The sensitivity and specificity ranged from 93-100% compared with PCR performed on purified Plasmodium DNA., Conclusions: The methodology described facilitates high-throughput testing of blood samples collected in the field by fluorescence-based real-time PCR. This method can be applied to a broad range of clinical studies with the advantages of immediate sample testing, lower experimental costs and time-savings.

This paper exploits the sharp escalation of violence in Colombia in the 1980s associated with the emergence of drug cartels to provide novel evidence on the long-run effects of violence exposure throughout the life-course, on children's educational attainment and academic achievement using administrative data. I find that, a higher homicide rate in early-childhood is associated with a higher probability of school dropout and conditional on completing high school, lower scores on a national end-of-high school exam. Results are robust to several falsification tests, and analyses of potential sources of selection bias. I provide supportive evidence that changes in fetal, child, and adolescent health outcomes are important potential mechanisms. [ABSTRACT FROM AUTHOR]

- Abstract
The new psychoactive substances (NPS) in Colombia are detected by national authorities, in blotters strip, in different circumstances and places: airports, music concerts, discos and parks. Blotters are marketed as LSD and cause several cases of intoxication and death in some consumers: due to acute intoxication or when mixed with other drugs and may have different effects on the central nervous system (CNS). This study was conducted to research into and identify the chemical composition of the drugs impregnated in the blotters sold in two Colombian cities. This research provides the analysis of 70 doses coming from forensic cases of the Colombian Attorney General's Office in Bogota and from the Laboratory of Narcotics of the Colombian National Institute of Legal Medicine and Forensic Sciences (North Headquarter) in Barranquilla. Mixtures of drugs, such as DOB, 25I-NBOMe, MDMA and 25I-NBOMe imine were found within the blotters through gas chromatography coupled to mass spectrometry (CGMS); these drugs are classified by international authorities as NPS belonging to the phenylethylamines group. The results clearly warn about a growing public health problem in the country., (Copyright © 2019 Elsevier B.V. All rights reserved.)

Tardigrades, with over 1450 species, are important organisms in ecological understanding and are valuable biological models (e.g., due to their extremotolerant capabilities). While their biodiversity is better known in Europe and North America, Central and South America have only recently started making significant contributions. Through a comprehensive review of scientific literature, biological collections, web portal consultations, and the addition of new records, this study clarifies the current knowledge of tardigrade biodiversity in Colombia. Past research started in the early 20th century, but most data are unreliable due to information gaps and the absence of specimens in biological collections. The last decade has witnessed a resurgence in tardigrade research in Colombia, leading to new species descriptions and a more robust understanding of their biodiversity. Nevertheless, the majority of the territory remains unexplored. A total of 43 known species from our analysis are present in Colombia: 26 records accepted by the literature and 17 questioned in the literature but representing distinct taxa surely present in Colombia. Other species records are considered doubtful. Our study recommends considering mostly scientific records based on verifiable material deposited in scientific collections (highlighting their importance in studying and safeguarding biodiversity) and encourages future researchers to contribute while adhering to legal requirements.

Background: This paper identifies opportunities and challenges for leishmaniasis control and elimination in Colombia, emphasizing the role of pooled procurement of essential medicines and supplies. Colombia is among the countries most affected by leishmaniasis globally, and also faces the dual challenge of procuring critically needed medicines in the context of limited national resources. It recently renewed its commitment to the control and elimination of leishmaniasis under its 2022–2031 Public Health Plan (PDSP) through a comprehensive public health approach. Methodology/Principal findings: The methodology comprises a comprehensive literature review and key informant interviews with leishmaniasis experts from the Colombian national control program and PAHO/WHO, focusing on cutaneous, mucocutaneous, and visceral leishmaniasis. Leishmaniasis is endemic throughout Colombia, with over 11 million people at risk, many of whom live in poverty-stricken, remote and isolated rural areas with limited access to health services. Leishmaniasis care, including medicines, is provided free of charge, but many barriers were nonetheless identified at environmental, population, and health system levels, including the supply of quality-assured medicines. Opportunities to alleviate these barriers were identified, including the support of the PAHO Strategic Fund. Within the context of the sustainable development goals and international leishmaniasis control and elimination targets, Colombian officials have established their own priorities, the highest of which is the reduction of deaths from visceral leishmaniasis. Conclusions/Significance: The elimination of leishmaniasis as a public health problem presents significant challenges, given its biological complexity and diversity, physical and clinical manifestations, social and economic impacts, frequently burdensome treatment regimens, and insufficient supply of necessary medicines. However, rigorous prevention and control efforts through strong political commitment and a highly motivated workforce can dramatically reduce its burden. Colombia's new PDSP, which highlights leishmaniasis control, is an opportunity for a revitalized health system response through committed leadership, intersectoral actions, and partnerships with international organizations that share a common vision. Author summary: Leishmaniasis is a vector-borne disease transmitted by female sand flies to humans and animals, causing infections ranging from asymptomatic and self-healing cutaneous leishmaniasis to visceral leishmaniasis which is highly lethal if untreated. Although all forms of leishmaniasis are treatable and curable with early diagnosis and treatment, the disease presents many challenges for affected populations, many of whom live in remote rural areas of the developing world, with limited access to public health facilities. Health services also face major constraints in supplying critically needed, yet costly medicines, in the context of limited financial resources. This paper presents the case of Colombia which is among the countries most affected by leishmaniasis globally, and discusses its many challenges in responding to the disease, including the guaranteed supply of necessary medicines. Our results uncover new opportunities for a revitalized health system response through committed leadership, intersectoral actions, such as a One Health approach, and partnerships with like-minded international organizations. These include Colombia's new 10-Year Public Health Plan that contains specific time-bound goals for leishmaniasis control and elimination as a public health problem, prioritizing a reduction in deaths from visceral leishmaniasis, and potential cost-savings from the acquisition of essential medicines and supplies through the Strategic Fund of the Pan American Health Organization.

This paper describes a novel qualitative dataset regarding coffee pests based on the ancestral knowledge of coffee farmers in the Department of Cauca, Colombia. The dataset has been obtained from a survey applied to coffee growers with 432 records and 41 variables collected weekly from September 2020 to August 2021. The qualitative dataset includes climatic conditions, productive activities, external conditions, and coffee bio-aggressors. This dataset allows researchers to find patterns for coffee crop protection through the ancestral knowledge not detected by real-time agricultural sensors. As far as we are concerned, there are no datasets like the one presented in this paper with similar characteristics of qualitative value that express the empirical knowledge of coffee farmers used to detect triggers of causal behaviors of pests and diseases in coffee crops.

Executive Summary: The near collapse of the Venezuelan economy since 2015 and the concomitant erosion of public order have led to an exodus of over seven million people by mid-2023, the largest forced migrant flow in recent Latin American history and the second largest globally after Syria. It occurs against a global backdrop of a 400 percent increase in persons displaced across borders between 2010 and 2021. Colombia hosts the largest number of Venezuelan refugees — with about 2.5 million officially recorded by the government. This has occurred during a politically tumultuous period in Colombia, which has featured the reconfiguration of competing illegal armed groups since the signing of the 2016 Peace Accord between the government and the Fuerzas Armadas Revolucionarias de Colombia (FARC), a major COVID-19 outbreak in 2020–2021, and a crippling and protracted national strike in 2021. Within the hemispheric context, Colombia serves as a stop-gap to stem the flow of Venezuelan refugees northward, roughly similar to the role played by Mexico to intercept and diminish migration to the United States. This has especially been the case since the January 5, 2023 announcement by US President Biden, which specified that refugees cannot declare asylum in the US if they attempt to cross the US border without first seeking asylum in their initial transit country. For Venezuelan refugees, the first country they enter is typically Colombia. Further, in May 2023, the Biden administration announced it was considering sending US troops to the Darien Peninsula in Panama, and will perhaps train Colombian forces, to diminish the "trafficking" of Venezuelan refugees and other refugees passing through Colombia and headed north. The result, according to leaders of NGOs and other who work directly with refugees, has been more pressure on Colombia to retain them. The argument here is twofold. First, human security threats for Venezuelan refugees should be viewed intersectionally in the particular spaces through which they pass — from the collapse of order in their home countries (which qualifies them as refugees), through the borderlands with Colombia that pose specific threats to their safety and wellbeing, and to their destinations within Colombia that offer their own peculiar array of opportunities and human security challenges. Second, regularization programs such as the Estatuto Temporal de Protección de Migrantes Venezolanos (ETPMV) are the best way to promote human security for refugees in Colombia in the short and medium terms, but this process needs to be more inclusive.
1 The first half of this paper discusses the conceptual underpinnings that link power/mobility/space to human security for refugees. The second part brings those concepts to life through interviews with an assortment of refugees. The paper draws from a database of interviews with 72 Venezuelan refugees in Colombia in 2022 and 2023 regarding the intersectional nuances of human security. It also relies on interviews with dozens of security, migration, and human rights experts in Colombia since 1997. A unique conceptual perspective is developed regarding critical human security for Venezuelan refugees. [ABSTRACT FROM AUTHOR]- Published

Implementing smart microgrids for Non-Interconnected Zones (NIZs) has become an alternative solution to provide electrical energy by taking advantage of the resources available through the generation of renewable energy within these isolated areas. Within this context, in this study, the challenges related to microgrids and data analysis are presented, and different relevant data architectures described in the literature are compared. This paper focuses on the design of a data architecture for a smart microgrid for NIZs whose microgrid contains two 260 W solar panels, a 480 W inverter, and two 260 Ah batteries. Regarding the Colombian context, this paper describes the limitations (connectivity, isolation, appropriation of technologies) and opportunities (low demand, access to natural resources, state interest) from which the functional and non-functional requirements for the architecture are established. Finally, a data architecture is proposed and implemented in a NIZ in Colombia, and this paper also includes a description of the architecture, its characteristics, its associated opportunities and challenges, and discussions regarding its implementation.

Objetives: The adoption of vaccines was a crucial factor in overcoming the COVID-19 pandemic. However, vaccination rates between rural and urban areas varied greatly. In this paper, our objective is to understand the individual and institutional factors associated with the uptake of vaccines in remote rural areas in Colombia. Methods: We interviewed a random sample of 800 households (1,592 individuals) in remote rural areas of Antioquia (Colombia) during February 2022 when vaccinations were available. Then, we use a linear probability model to explain the uptake of the COVID-19 vaccine. Results: The results indicate that the probability of having at least the first dose of the COVID-19 vaccine is positively associated with access to information, trust in police and army, and the perceived risk of contracting COVID-19. Trust in the church is negatively related to vaccination. Conclusion: Institutions can play a critical role in the management of pandemics. Timely information on the risks associated with the disease and perceived riskiness are key factors that mobilize the population to take the COVID-19 vaccine. [ABSTRACT FROM AUTHOR]

Multi-stakeholder participation processes in watershed management face challenges due to limited monitoring and baseline data, resulting in a lack of awareness among stakeholders about the current state of the watershed. This knowledge gap often leads to conflicts of interest, wherein the broader impacts of individual decisions are overlooked. To overcome these limitations, this paper explores the design and implementation of a Serious Game (SG) aimed at coproducing a watershed management plan at the basin scale within the specific context of the Campoalegre River basin in Colombia. By providing an interactive platform, the SG facilitates collaboration between local actors, who may be unfamiliar with existing watershed plans, and decision-makers. The goal is to create a participatory space where stakeholders can comprehend the watershed management plan structure and prioritize actions based on various climatic, social, and economic conditions. Following the application of the SG, stakeholders demonstrated an improved understanding of the basin, fostering increased participation, open debate, and the proposal of actions. These outcomes serve as valuable inputs for the implementation of water management planning policies, showcasing the potential of SGs in bridging knowledge gaps, and fostering effective multi-stakeholder engagement.

This study presents a conceptual framework proposal for integrating urban freight initiatives (UFIs), or city logistics initiatives, into urban planning and urban management (UPUM) land use and infrastructure systems. As a novel approach, this framework integrates three components: Firstly, a conceptual basis on three economic geography theory principles—location, agglomeration, and urbanisation. Secondly, spatial analysis and subsequent clustering integrate companies' spatial positions, their proximity to other companies, their freight intensity, and the characteristics of the zonal road infrastructure; these clusters are defined as freight traffic zones (FTZs). Thirdly, a functional yet strategic UFI clustering or grouping is proposed to work in an optimised and integrated manner with the FTZs' opportunities for efficiency and reduced externalities. It is expected that the integrated result of these three components can serve to optimise freight initiatives and road infrastructure from a city governance perspective, reduce freight externalities, and function as a stakeholder cooperation tool from government-led, policy-driven perspectives. This research also identifies and characterises various variables influencing the emergence and existence (planned or organic) of FTZs and shows how these could be incorporated into high-level UPUM processes. Although it is deemed that the principles and methodological approach followed here could be common to urban areas, an example for the Metropolitan Area of the Aburra Valley (MAAV), in Colombia, is presented as an initial case study. Conclusively, this paper introduces a pioneering methodology for integrating UFIs into city or metropolitan governance, offering guidance for policymakers to promote sustainable freight systems.

Purpose: This study aims to measure the gender wage gap among millennial workers in Colombia and determine if there is a marked wage difference between millennial women and men. Furthermore, this study analyzes whether millennial women face a glass ceiling, that is, whether there is a larger gender wage gap among workers earning relatively high wages. Design/methodology/approach: The study data included a sample of 2,144 millennial workers employed in 11 organizations located in the five main cities of Colombia. Oaxaca–Blinder econometric methods of wage decomposition were used to calculate both raw and adjusted gender wage gaps. The latter results in estimating the gender wage gap while controlling for observable characteristics related to individual, family, and labor. In addition, wage decompositions by education levels were carried out to approximate the extent of the glass ceiling among young workers. Findings: The results show that millennial workers in Colombia face gender inequality in the labor market and that professional millennial women experience a distinct glass ceiling. The adjusted gender wage gap is 9.5%, and this gap increases with education level, increasing to nearly 14% among college-educated workers. Research limitations/implications: The empirical results are supported by a self-report survey of millennial workers. An important limitation is that the data include millennial workers employed in the formal sector and exclude the informal sector (activities not regulated or protected by the state), which represents an important part of the economy in developing countries. Originality/value: This paper contributes to the empirical literature on gender wage inequality for younger workers. This paper is original in reviewing the gender pay gap in Colombia using a primary dataset. Most of the work in this area has been done in developed countries and this research adds to the findings that have had focused on those nations. [ABSTRACT FROM AUTHOR]

Against the backdrop of ongoing planetary crises, this paper discusses the ambivalent relationship between large-scale material infrastructure, particularly energy technologies, and environmental justice. Inspired by relational and practice-oriented understandings of infrastructure, it develops a conceptual approach for energy-related environmental justice research, which is exemplarily applied to the emerging issue of green hydrogen, drawing on brief insights from the hydrogen frontrunner countries Colombia and Canada and associated struggles over Indigenous sovereignty. This "infrastructural lens", based on three epistemological shifts – from infrastructure to "infrastructuring", from social imaginaries to "sociotechnical imaginaries" and from human infrastructuring to "planetary infrastructuring" – provides deeper insights into how patterns of justice and injustice are practically infrastructured and what kinds of imaginaries they evoke or are entangled with. Moreover, it makes tangible how practices of infrastructuring can themselves become part of a broader political ontology, that is, of struggles over ways of being and ways of relating to planet Earth.

The purpose of this paper is to present an exploration on the response of parents of two rural multigrade schools facing the homeschooling activities in the context of pandemics. To frame a comparative perspective some conceptual work was done about new rurality and family structure before interviewing parents of both schools about distribution of tasks among family members, distribution of time and technological support. The study concluded that the traditional structure of rural families made easy to carry on with the tasks of home, labor and education. [For the complete Volume 21 proceedings, see ED629259.]

- Abstract
Demographic features are commonly used in Educational Data Mining (EDM) research to predict at-risk students. Yet, the practice of using demographic features has to be considered extremely problematic due to the data's sensitive nature, but also because (historic and representation) biases likely exist in the training data, which leads to strong fairness concerns. At the same time and despite the frequent use, the value of demographic features for prediction accuracy remains unclear. In this paper, we systematically investigate the importance of demographic features for at-risk prediction using several publicly available datasets from different countries. We find strong evidence that including demographic features does not lead to better-performing models as long as some study-related features exist, such as performance or activity data. Additionally, we show that models, nonetheless, place importance on these features when they are included in the data--although this is not necessary for accuracy. These findings, together with our discussion, strongly suggest that at-risk prediction should not include demographic features. Our code is available at: https://anonymous.4open.science/r/edm-F7D1.

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.

Obstructive sleep apnea/hypopnea syndrome (OSAHS) is a condition linked to severe cardiovascular and neuropsychological consequences, characterized by recurrent episodes of partial or complete upper airway obstruction during sleep, leading to compromised ventilation, hypoxemia, and micro-arousals. Polysomnography (PSG) serves as the gold standard for confirming OSAHS, yet its extended duration, high cost, and limited availability pose significant challenges. In this paper, we employ a range of machine learning techniques, including Neural Networks, Decision Trees, Random Forests, and Extra Trees, for OSAHS diagnosis. This approach aims to achieve a diagnostic process that is not only more accessible but also more efficient. The dataset utilized in this study consists of records from 601 adults assessed between 2014 and 2016 at a specialized sleep medical center in Colombia. This research underscores the efficacy of ensemble methods, specifically Random Forests and Extra Trees, achieving an area under the Receiver Operating Characteristic (ROC) curve of 89.2% and 89.6%, respectively. Additionally, a web application has been devised, integrating the optimal model, empowering qualified medical practitioners to make informed decisions through patient registration, an input of 18 variables, and the utilization of the Random Forests model for OSAHS screening.

The Hispanic Society Museum & Library (HSML) holds a collection of nine viceregal barniz de Pasto objects, made by Indigenous artisans in the 17th and 18th centuries. Designed to imitate Asian lacquers and intended for European aesthetic tastes, barniz de Pasto is an example of Indigenous technique and knowledge that has survived to the present day. An in-depth analysis of five of these barniz de Pasto objects, dated to the first half and last quarter of the 17th century based on their iconography, was carried out through a combination of non-invasive and micro-invasive techniques, including portable X-ray fluorescence (pXRF) spectroscopy to investigate the possible presence of inorganic pigments, and fiber-optics reflectance spectroscopy (FORS) and reflectance imaging spectroscopy (RIS) to provide molecular information on colorants and their distributions across the objects. Dyes and pigments were also identified using Raman spectroscopy, Fourier-transform infrared (FTIR) spectroscopy, and liquid chromatography/mass spectrometry (LC/MS). The nature of the resin was determined by FTIR and pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS), while the decoration stratigraphy and composition were analyzed by scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS). This paper confirms the use of mopa mopa, the resin used in the barniz de Pasto technique, in two objects not previously analyzed, and identifies indigo, insect-based red, calomel, lead white, and an unknown flavonol-based yellow dye, and challenges the use of calomel as a temporal marker for these works. Taken together, these results expand our understanding of the material use and explorations undertaken by artists during this time period to create such elaborate and enduring objects.

INSPECTION & review ,DATABASES ,BRIDGE inspection ,CATALOGS ,CHEMICAL processes - Abstract
Road structures undergo a series of chemical and physical processes once they are put into service. This phenomenon results from the action of the load and the influence of the environment, which causes their progressive deterioration. In order to mitigate the risk of progressive deterioration and guarantee their stability and durability, various maintenance tasks are required, including visual inspections. The Intelligent Bridge Management System of Colombia (SIGP) includes visual inspection as one of its modules. The system has been designed based on state-of-the-art criteria and national experience with relevant damages and bridge collapses. This paper presents the visual inspection methodology, which includes several stages such as a classification scale, condition index, evaluation areas, damage catalog, and evaluation criteria. In addition, a digital application has been developed to facilitate real-time data collection during field inspections using mobile devices, which can be uploaded directly to the system database hosted in the cloud. The results from the inspection of bridges of different typologies and years of construction are presented, as well as general inspection results from 150 bridges in Colombia. The relevance, comprehensiveness, and accuracy of the inspection are supported by a damage catalog, which allows the identification of intervention needs and reduces the bias of the collected data.

This paper presents two datasets about college students' subjective well-being and mental health in a developing country. The first data set of this report offers a diagnosis of the prevalence of self-reported symptoms associated with stress, anxiety, depression, and overall evaluation of subjective well-being. The study uses validated scales to measure self-reported symptoms related to mental health conditions. To measure stress, the study used the Perceived Stress Scale (PSS-10) and the 7-item Generalized Anxiety Disorder Scale (GAD-7) to measure symptoms associated with anxiety (GAD-7), and the 9-item Patient Health Questionnaire (PHQ-9) to measure symptoms associated with depression. This diagnosis was collected in a college student sample of 3052 undergrad students in 2022 at a medium-sized university in Colombia. The second dataset reports the evaluation of a positive education intervention implemented in the same university. The Colombian Minister of Science and Technology financed the intervention to promote strategies to mitigate the consequences on college students' well-being and mental health after the pandemic. The program evaluation data cover two years (2020–2022) with 193 college students in the treatment group (students enrolled in a class teaching evidence-based interventions to promote well-being and mental health awareness) and 135 students in the control group. Data for evaluation include a broad array of variables of life satisfaction, happiness, negative emotions, COVID-19 effects, relationships valuations, and habits and the measurement of three scales: The Satisfaction with Life Scale (SWLS), a brief measurement of depressive symptomatology (CESD-7), and the Brief Strengths Scale (BSS).

Executive Summary: Millions of Venezuelans have fled their country in hopes for a better future outside the political and financial turmoil in their home country. This paper examines the self-reported needs of Venezuelans in the United States and Colombia. Specifically, it looks at perceived discrimination in each country and its effect on the service needs of Venezuelan immigrants. The authors used data from a larger project conducted in October to November 2017 to perform a qualitative content analysis on the specific services that participants and others like them would need following immigration. The sample consisted of 647 Venezuelan immigrant adults who had migrated to the United States (n = 342) or Colombia (n = 305). Its findings indicate statistically significant differences between the two countries. Venezuelan immigrants in the United States were more likely to identity mental health and educational service needs, while those in Colombia were more likely to list access to healthcare, help finding jobs, and food assistance. When looking at perceived discrimination, means scores for discrimination were significantly greater for participants who indicated needing housing services, who indicated needing assistance enrolling children in school and who indicated needing food assistance, compared to participants who did not list those needs. Venezuelans who had experienced greater negative context of reception were less likely to indicate needing mental health services, where 11.9 percent of those who did not perceive a negative context of reception responded that they needed mental health services. Evaluating existing service networks will be essential in working to bridge the gap between the services provided to and requested by Venezuelans. Collaboration between diverse government actors, community-based organizations (CBOs) and other stakeholders can help identify gaps in existing service networks. CBOs can also facilitate communication between Venezuelan immigrants and their new communities, on the need to invest in necessary services. [ABSTRACT FROM AUTHOR]

NINETEENTH century ,STREAMFLOW ,UTOPIAS ,POLITICAL agenda - Abstract
This paper examines how utopian river planning has arisen in Colombia and Spain since the late nineteenth century. Specifically, the paper contributes to understanding how particular ideologies of modernism and development present in territorial planning connect both countries. Taking Thomas More's classic work 'Utopia' as the analytical reference, I analyze how utopian tendencies have traveled through time and space to shape territorial planning and water governance. In both countries, this was evident in the late nineteenth century through the political project to strengthen the nation state. For Spain, I describe the regenerationist movement and the hydraulic utopia led by the Spanish intellectual Joaquín Costa, who forged the dream of a water nationhood. By contrast, in Colombia, several political intellectuals looked at Europe and North America as a source of inspiration to achieve progress by controlling rivers. Through the method of disjunctive comparison, I show how the same utopian notions are expressed in similar ways in distinct contexts: violently governing the flows of rivers, standardizing minds and ordering territories towards capital growth. This paper contributes to grasping the notions and roots of the discourses that have colonized the political water agendas in both countries. [ABSTRACT FROM AUTHOR]

In their article "Ancient gold pectorals from Colombia: Mushroom effigies?" Richard Evans Schultes and Alec Bright gave enough reasons to assure the reader that some goldsmithing pieces exposed mostly in the Museo del Oro located in Bogotá, Colombia that are part of the objects named "Darien Pectorals", are representations of mushrooms. This is evidence of a mushroom cult that was practiced by the inhabitants of the places where these pieces where produced and found. Some of these pieces are located in private collections and museums all over the world. Such ornaments denominated "Darien Pectorals", were not limited to a single region. They mentioned in their article that, these ornaments are not confined to one region, although their greatest concentration seems to be in the Sinu country in northwestern Colombia, near the border with Panama's Darien Province. They are found also in the Quimbaya region of Colombia, farther south." In another part of the article, we find the following: "Interestingly, one such "Darien pectoral" has been found as far north as Chichen Itza in Yucatan, where it undoubtedly found its way as an item of long-distance trade, along with other lower Central American and Colombian gold artifacts." The purpose of this paper is to contribute to the ethnomycological knowledge of Colombia, continuing what was proposed by Schultes and Bright, reinforcing their ideas with new evidence based on specialized bibliography and regular visits to the Museo del Oro in Bogotá to the Zenú Collection with the purpose of analyzing the pieces and finding indications that may suggest the possible use of hallucinogenic mushrooms by the indigenous culture of pre-Hispanic Colombia.
