- 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.

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.

SCIENCE publishing , *LANGUAGE ability , *LINGUISTICS , *SCIENTIFIC language , *ENGLISH language , *COMPUTER assisted language instruction - Abstract
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]

WASTEWATER treatment , *PAPER industry , *WASTE paper , *RECYCLED products , *RAW materials , *WASTE recycling - Abstract
The wastewater treatment at paper industry that uses recycled fibers as one of its raw materials generates a sludge rich in cellulose fibers, which once dehydrated is called "paper waste". This waste has become an environmental problem because of its high generation rate. Although several alternatives of valorization have been studied, in Medellin none of them has been implemented on an industrial scale; the necessity is still there, that is why the land disposal of this waste appears as the most immediate way to manage it. Combined with the problem of disposition, it is the selection of the suitable site to make it, for which a methodology to be applied in the evaluation and selection of the optative sites for the disposition of remainders of paper industry was developed.

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]

- Abstract
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.

This paper examines the web tools used by two Colombian daily papers (El Tiempo, from Bogotá, and El País, from Cali) in order to interact with their readers. For our research we used a matrix to help us classify the abovementioned tools vis-à-vis the different extent of the interactions, the latter understood as the range of possibilities offered by the media to their users in order to modify, produce, and communicate content with both the original transmitters of information and other users. In the case of the papers herein examined, we found that, in spite of the fact that they do offer tools which in fact do bring about interactivity, the latter revolves around three main aspects: adaptability, browsing, and feedback, whereby the user remains at a first level (that of reading the texts) but is not yet allowed to co-produce the content.

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]

An emergent literature has shown that some students overcome adversities related to their low Socio-Economic Status (SES) by attaining high academic achievement. One of the aims of this literature is to identify the factors that explain the capacity of students from low SES backgrounds to attain high academic achievement. However, upon reviewing this literature, I observed that few studies have comparatively investigated the associations between the capacity of students from low SES backgrounds to attain high achievement in reading and school climate characteristics. Additionally, I found that not many studies have researched whether student SES moderates these associations. This paper contributes to fill these two gaps by estimating associations between high achievement in reading and school climate characteristics. Moreover, it examines whether student SES moderates these associations. To do this, this research estimated logit and heterogeneous choice models using representative samples of students from Argentina, Brazil, Chile, Colombia, and Uruguay who participated in the 2018 Programme for International Student Assessment (PISA). The results show that high achievement in reading is positively correlated to certain teaching practices, such as perceived teacher enthusiasm during the instruction and adapting instruction to students' needs. Conversely, it is negatively correlated to teacher feedback and teacher-directed instruction. Furthermore, the findings indicate that high achievement in reading is negatively correlated to the scarcity and low quality of educational material. Interestingly, the results show that student SES does not moderate these associations. In conclusion, these findings indicate that interventions targeting these areas of school climate may help to increase students' probability of attaining high achievement in reading, regardless of their SES. Likewise, these results suggest that if these interventions are focused in low SES schools, they may contribute to bridge the gap in reading skills between students from low and middle or high socioeconomic backgrounds.

Introduction: This article presents a model of political competition in which political parties, through clientelism strategies, vie for control of legislative seats. Parties exercise political violence to prevent potential rivals from gaining power and threatening their position within the hybrid political regime. The theory suggests that the degree of political violence exerted by parties in hybrid regimes will increase (decrease) as they concentrate more (less) power in the legislature. Methods: Using the methodology of analytical narratives, we examine the narrative on political violence in the Colombian political regime to identify key actors, strategies, information sets, and institutional changes. From these identified elements, we construct a theoretical model of political competition within the mathematical theory of games to explain the institutional changes highlighted in the narrative. Finally, we develop an econometric model to find statistical evidence supporting the predictions of the theoretical model derived from the narrative. Results: The narrative and the analytical narrative indicate that, in a hybrid regime, a higher degree of political power concentration causes a higher rate of political violence. The estimation of the Vector Auto-regression model allows us to analyze the response of the violence rate to a shock in the concentration index. Following an unexpected increase in the concentration of political power, the violence rate shows an initial increase of approximately 0.3 percentage points above its initial value. Subsequently, the effect attenuates slightly and stabilizes at around 0.2 percentage points above the baseline, maintaining this level throughout the period. Discussion/Conclusion: The theoretical model proposed in this paper suggests an explanation of political violence that diverges from the explanations offered by traditional theories. We suggest that the theoretical model proposed here captures the historical logic of the relationship between violence, political clientelism, and exclusion in Colombia, a country with a relatively long tradition as a formal democracy (since 1958), leading us to interesting conclusions that have not been proposed so far in the literature on violence in Latin America.

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.

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.

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

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]

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.

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.

- 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.

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.

This paper brings together the tale "Canciones para el incendio" of the colombian writer Juan Gabriel Vásquez, with the hermeneutic thinking of Ricoeur supported, in some traits, by Husserl's phenomenology. From a hermeneutic standpoint, the three-fold mimesis model enables the methodology developed in this paper, which unfolds into three approaches to the tale. The mimesis proposes three steps that include prefiguration, configuration and refiguration; issues that respond to the relationships between time lived and narrative. Its unfolding nestles in a sort of time relaxation, that brings closer the before and after of the narrative. The key questions are: what mimics the tale? mimesis I, how is it set up? mimesis II and, lastly, what does the refiguration of the tell means, when the reader inhabits in it? mimesis III. Vásquez's work is impressive not only for its literary quality, but also for putting in the spotlight the most pitiful aspects of the historical reality of violence and exclusion that Colombia has endured, witnessing the poor democracy experience and secularization; values and truths that are scarcely instituted in this nation.

Martins, Claudia Beatriz and Werner, Maristela
- Abstract
The objective of this paper is to report the preliminary results of a telecollaborative project between a Brazilian university (UTFPR) and a Colombian university (Universidad de Pamplona) that both offer a Licentiate degree in English. The project had two purposes: a pedagogical one to show student-teachers how they can develop their communication skills in English in a collaborative way by sharing information with other student-teachers from a different culture, and a technological one to put future teachers in contact with some technological tools. The paper is divided into three parts: (1) a brief description of the context and the participants; (2) the project itself -- the first steps, the objectives, and the tasks; and (3) the Brazilian view of the whole process/project as well as the students' feedback.
