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.

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.

The migration of Venezuelans nationals to other Latin-American countries has been defined as the most significant migratory phenomenon in the recent story of the region, with Colombia being the country that hosts the highest number of Venezuelan nationals. From a human rights perspective, this article critically analyzes the response of the Colombian State to address migration from Venezuela. The objective of this article is to show that Colombia has preferred to govern this migration through the creation of ad hoc permits, instead of recognizing the need for international protection of this population and their status as refugees. To this end, this paper analyzes the Colombian regulatory framework on migration and refuge and, in particular, the response of the Colombian State to the migration of people from Venezuela. Its central argument is that the Colombian authorities have opted for the design and implementation of alternative measures of migratory regularization, as it was at the time the Special Permit of Permanence and is today the Permit for Temporary Protection. This article concludes by stating that the approach to Venezuelan migration has led to a clear detriment to the refugee system, today collapsed and with no prospect of reform or strengthening. This is so because the institutional design of the Colombian refuge entails a host of obstacles that discourage applicants from following this path, even when they require international protection. The authors of this paper use legal dogmatic as the main research methodology. [ABSTRACT FROM AUTHOR]

This paper explores the determinants of rural-urban student performance in Colombia, a nation characterized by pronounced inequality. Using quantile regression, a student-level education production function at different points along the achievement distribution is estimated. Using the Oaxaca–Blinder decomposition, estimates are provided to explain the achievement differential between urban–rural students. These estimates account for various factors including individual, family, and school characteristics. Results indicate that mean differences in performance between students in rural and urban Colombian schools are significant. Observable factors, especially school characteristics, are the main drivers of the performance gap. Substantial differences are observed when different test percentiles of the performance distribution are considered. Our results suggest that one way in which education can reduce student performance gaps is by investing in improving school quality in rural areas. [ABSTRACT FROM AUTHOR]

This article presents an investigation of the main causes of migration of the Wayuu to urban areas of Colombia and Venezuela and the effect this has caused on the contact between Wayuunaiki and Spanish. Through interviews, ethnographic observations and bibliographic consultations, we identify the voluntary and forced causes of this long-lasting migration that continues to develop. The settlement in urban areas and the growing bilingualism of the Wayuu facilitates the development of an ethnolect specific to the ethnic group, distinguished by the use of lexical borrowings, morphosyntactic combinations and codeswitching. This paper contributes to the existing literature by identifying more features and examples of the products of this linguistic and cultural contact. [ABSTRACT FROM AUTHOR]

Young people in Colombia present high rates of mental health problems, to which the country’s history of armed internal conflict contributes in complex ways. Mental health services in Colombia are fragmented, inadequate, and difficult to access for many. Young people’s help)seeking is often hindered by mental health stigma and/or poor experiences with services. This paper presents a thematic analysis of qualitative data from a mixed-methods study aimed at developing and testing a mental health intervention for Colombian youths. We draw upon theoretical lenses from scholarly work on stigma and Sen’s ‘capabilities approach’ to inform our analysis of interviews and group discussions with staff and young people involved in the state-funded human capital building programme ‘Jovenes en Acción’ (JeA). By illustrating how study participants talked about stigma, vulnerability, mental health services organisation, and the challenges of discussing mental health topics in a learning environment, we illuminate aspects of mental health support and anti-stigma interventions that might need enhancing. In particular, we suggest that more emphasis on ‘community competencies’ as complementary to and interrelated with individual competencies would strengthen young people’s individual and collective resources for mental wellbeing while being in line with the sociocritical principles of existing human capital-enhancing programmes.

The objective of this paper is to suggest a mathematical model of unpaid housework and empirically test its main predictions using data from Mexico (2014) and Colombia (2017) time-use surveys. The model, based upon the Marxist-feminist approach, suggests that the magnitude of unpaid housework is determined by the super-exploitation of labor, i.e. the gap between wages and the value of labor-power. The outcome is an equation that relates positively the magnitude of unpaid housework with the super-exploitation of labor. The parametric and nonparametric regression estimates applied in both countries show preliminary empirical support for the theoretical model. The theoretical and empirical findings have several implications for Marxist-feminist literature as well as for empirical research on unpaid housework. [ABSTRACT FROM AUTHOR]

Objective/context: The article aims to analyze child recruitment as a form of human trafficking. Beyond the theoretical perspectives that focus on security or rights, it addresses the topic as a form of unfree labor. By means of a case study focused on child recruitment by right-wing paramilitary groups in Colombia, the paper analyzes how children entered and exited illegal armed groups, the functions they performed, and the exploitation they endured. The research argues that child recruitment operates as a large-scale labor-market uptake in the wartime social order, where the “employers” are paramilitary groups, and the labor force, in part, consists of children and adolescents. Methodology: This case study relies on different sources of information: a database on child recruitment provided by the special Justice and Peace Unit of the Colombian Attorney General’s Office (989 cases between 1981 and 2005), sentences of Peace and Justice, testimonials given by victims in judicial processes, and semi-structured interviews with different actors. Conclusions: The paper shows that child recruitment as a form of trafficking is functional to wartime social order in contexts of poverty and inequality. There is demand and supply; thus, both girls and boys, who worked as soldiers, are not only victims but also agents that make decisions in challenging conditions. Therefore, if the socioeconomic options for these children, even after their demobilization from the armed group, are still a choice between bad and worse, joining a violent (no longer “armed” but “criminal”) group will remain a feasible alternative. Originality: The article contributes to the academic literature on a recent topic, such as the overlapping between child recruitment and human trafficking in armed conflict and post-conflict situations. It also contributes to the literature on “unfree labor,” as the study focuses on an actor (illegal armed groups) that has not been analyzed until now. Finally, the research demonstrates the limits of understanding human trafficking (and child recruitment as a form of trafficking) as a problem of security or rights entitlement. It highlights the analytical and political advantages of categories such as “unfree labor” to provide effective solutions for the prevention and reintegration of child soldiers.

Background: Rickettsiae are obligate intracellular Gram-negative bacteria that are the causative agent of rickettsioses and are spread to vertebrate hosts by arthropods. There are no previous reports of isolation of Rickettsia amblyommatis for Colombia. Methods: A convenience sampling was executed in three departments in Colombia for direct collection of adult ticks on domestic animals or over vegetation. Ticks were screened for the presence of Rickettsia spp. by real-time polymerase chain reaction (qPCR) amplifying the citrate synthase gene (gltA), and the positive sample was processed for isolation and further molecular characterization by conventional PCR. The absolute and relative frequencies were calculated for several tick species variables. All products from conventional PCR were further purified and sequenced by the Sanger technique. Representative sequences of 18 Rickettsia species were downloaded from GenBank. Consensus phylogenetic trees were constructed for the gltA, ompB, ompA, and htrA genes with 1000 replicates, calculating bootstrap values through the maximum likelihood method and the generalized time reversible substitution model in the MEGA 7.0 software program. Results: One female Amblyomma mixtum collected on vegetation was amplified by qPCR (gltA), indicating a frequency of 1.6% (1/61) for Rickettsia spp. infection. Sequence analysis of a rickettsial isolate from this tick in BLASTn showed 100% identity with gltA (340 base pairs [bp]), 99.87% for ompB (782 bp), 98.99% for htrA (497 bp), and 100% for ompA (488 bp) to R. amblyommatis. Concatenated phylogenetic analysis confirmed these findings indicating that the isolate is grouped with other sequences of Amblyomma cajennense complex from Panama and Brazil within the R. amblyommatis clade. Conclusions: This paper describes the isolation and early molecular identification of a R. amblyommatis strain from A. mixtum in Colombia. [ABSTRACT FROM AUTHOR]

This paper shows the results of research conducted with the objective of knowing the perceptions of people in Colombia about the possibility of receiving a universal basic income, which does not exist thus far in the country. The research question was: how do the social perceptions of Colombians about receiving a UBI allow them to understand the possibilities of developing a public policy that guarantees it? A qualitative methodology of grounded theory was applied by conducting 37 in-depth interviews with adults of all socioeconomic levels, all educational levels and productive working age. The information obtained was coded. The resultant main categories with which the Grounded Theory was built were mistrust in others, hope for a better society, unconditional support, and implementation scenario. It was concluded that, if there is an intention to implement the UBI in Colombia, there must be policies that contribute to changing the mistrust and fear of citizens to receive support from the State by solidarity and equity so that UBI can be assume as a right that contributes to the construction of justice and social welfare.

This paper presents a compendium of good practices detected from the application of the Social Profitability Indicator in Communication IRSCOM to a group of 12 community and indigenous public interest stations in Colombia during the year 2022. The IRSCOM-RADCC (Radio Comunitaria Colombia) is a tested methodology that is specified in 33 indicators and is designed to collect quantitative and qualitative information on the internal functioning of the media in relation to six categories of analysis: management, social capital, territorial and citizen articulation, programming, Internet activity and infrastructure. The information collected goes through a weighting process that results in numerical scores for each of its variables allowing to observe strengths and weaknesses. The tool facilitates the collection of qualitative information in the form of good practices for each of its variables, thanks to the results of the semi-structured interview that accompanies the IRSCOM implementation methodology. The results have shown ingenious ways by radios to self-manage, as well as loyalty participation, both in management and in the realization of programs. There is also a growing interest in diversity and differential aspects in the configuration of social capital and in the programmatic contents as well as a high level of linkage with the social fabric. All this makes them the axis of territorial structuring and enhancement of proximity communication. [ABSTRACT FROM AUTHOR]

This paper studies the relationship between Marxism and social sciences in Estudios Marxistas. Revista colombiana de ciencias sociales, published between 1969 and 1987 by a group of intellectuals of the Communist Party. The central argument argues that the appearance of this publication, its production dynamics, its interpretation of Marxism and social research, as well as the debates it generated, can be explained by the need of this group of intellectuals to dispute the nascent academic field, where intellectual nuclei of the "new left" had great influence. In order to develop this argument, the paper is structured in four parts. The first reconstructs the political and intellectual context in which Estudios Marxistas emerged and examines the project it outlined. The second describes the dynamics of its scientific production. The third part studies some of the uses that the research presented therein made of the Marxist tradition. The fourth part analyzes the critique of the Estudios Marxistas editorial group of the "new history" current. [ABSTRACT FROM AUTHOR]

Using estimations by Bresser-Pereira et al. (2021), this paper analyses the misalignment between the real exchange rate and the current account equilibrium exchange rate in Colombia in the last two decades (2000-2020). Evidence suggests that the commodity boom and bust cycle in this period is important to explain (i) the main trend of the misalignment, (ii) the deterioration of the current account in recent years and (iii) the general macroeconomic performance of the Colombian economy. A discussion about macroeconomic development and stability is also provided in the context of the Colombian financial configuration, characterized by a flexible exchange rate regime, central bank independence and inflation targeting. Ideas in this paper are consistent with key elements in the New Developmentalism Theory. [ABSTRACT FROM AUTHOR]

Nasa Yuwe (ISO 639-3 pbb, formerly Páez) has been characterized as a language featuring a substantial inventory of both consonants and vowels, displaying intricate phonological categories. Moreover, various forms of complex syllable onsets have been observed in modern variations of this language. Given the absence of any documented languages closely related to Nasa Yuwe, a comprehensive understanding of the variation and evolution of its intricate phonological system necessitates a process of internal reconstruction. This paper outlines recent advancements in this area, resulting from a comparison between the only known written source of Páez from the Colonial period and data from contemporary Nasa Yuwe varieties. This initial study primarily focuses on the diachronic process of vowel deletion and its correlation with the emergence of double onsets and palatalization in contemporary Nasa Yuwe.

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.

This paper aims to estimate the probability of growth aspirations of Colombian entrepreneurs according to the generation in which they were born. There is a large literature on the determinants of the growth aspiration, but there is not much empirical evidence on the possible effects of belonging to a specific generation. We used data from the Global Entrepreneurship Monitor for the period between 2006 and 2017. Specifically, the data were taken from the Adult Population Survey, which measures certain relevant characteristics of entrepreneurs around the world. Based on a sample of 6,670 individuals, three ordinal logistic regression models were estimated, one for each generation: Baby Boomers, Generation X and Generation Y-Millennials. The results show that the youngest entrepreneurs, the Millennials, have a very different conception of life than their predecessors in relation to their view of entrepreneurship as a life choice. In fact, structural factors such as gender, education and motive for entrepreneurship are significant for all generations. However, context-related factors such as their skills, fear of failure, recognition, and their view of entrepreneurship as a desirable career have different effects on each generation. These results are relevant for the development of public policies and business strategies associated with entrepreneurship in developing regions. [ABSTRACT FROM AUTHOR]

The first organized feminist movement in Colombia demanded the right for women to vote in 1954 and, despite its progressist agendas and decades of work, it still tends to be distorted by traditional media representation. With social media, these activists can reach the audience directly, disseminate information, and dispute narratives. Hence, this study addresses the question: how are the discourses about feminism constructed on Instagram in Colombia? Based on netnography and critical discourse analysis, the paper analyzes the discussions on publications and comments on the most popular feminist Instagram account in Colombia, @ LasIgualadas. The results indicate that the platform usage could help create a less stereotypical perspective on the movement while informing society on its agendas and raising awareness about rights violations. However, the debate on @LasIgualadas is still predominantly carried out by women (80.5%), and some topics, such as abortion and LGBTQI+ rights, are distorted or deviated from by some Instagram users’ comments.

The primary application of base isolation around the world is in buildings and bridges; however, it could be applied in any structure. The technique has some limitations that, theoretically, reduce its efficiency, such as in tall buildings and soft soil conditions. In this paper, a non-conventional seismic isolated structure is studied to evaluate the benefits of the technique on it. Specifically, a stadium grandstand located in Colombia with hard and soft soil conditions beneath the isolated base is analyzed. The considered structure is important due to its necessity for seismic risk mitigation. It will have a high number of people to evacuate safely during earthquakes, and after them, it could be designated as a humanitarian shelter. The results a) show structural benefits principally in hard soil conditions, b) corroborate and quantify the limitations in soft soil, and c) make recommendations to isolate structures under the conditions studied here.

Marine Natural Products (MNPs) isolated from samples collected in Colombia have been an object of study since the early 1980's; however, this information is neither integrated nor compiled. This systematic review describes the articles published in scientific journals up to December 2019. 173 papers met the inclusion criteria of focusing on MNPs obtained from specimens collected from Colombian seas; all original papers written in English, Portuguese or Spanish. The selected papers were mostly authored by researchers from Colombian groups, with low interaction amongst themselves. 99.4% of the papers studied samples collected from the Caribbean Sea; 183 species were studied, mainly sponges and octocorals. In this study, 1,690 compounds (238 new ones) were reviewed, mainly diterpenes and sterol derivatives. Of the selected papers, 76.8% measured various biological activities, including antibiotic (34%) and anticancer (30%). These papers were published in 51 journals (74.6% were international). In conclusion, scientific work on natural marine products of Colombian origin has incremented over time. The most relevant opportunities to address and fill existing gaps comprise: exploring Pacific Ocean organisms and several of the misrepresented taxa; promoting strong interactions amongst the MNPs research groups, and accordingly with other areas of knowledge; and having the productive sector participate in MNPs research.

This paper concerns the study of Colombian foreign policy. Specifically, it applies foreign policy analysis (fpa) methods to the study of Colombian international politics and international relations. Embarking from the analytical framework of International Regimes, the work describes a specific approach to their study, and thereafter traces the process that preceded Colombia's accession to the Organization for Economic Cooperation and Development (oecd). It analyzes how the decision to join the oecd is best understood as a foreign policy strategy on the part of the national government. The paper also offers a preliminary evaluation of the process of institutional adaptation accompanying oecd membership and its impact on Colombian society. The article is based on the analysis of primary sources related to the decision-making process carried out by both the national government and the oecd. Additionally, it uses a variety of other sources to illuminate a foreign policy strategy implemented in a complicated international context, one only made more difficult by the onset of the Covid-19 pandemic. In this manner, the paper discusses the challenges and importance of oecd membership, including the delay of its formalization to the point of coinciding with the Covid-19 pandemic. Such unfortunate timing has likely contributed to the perception among many Colombians, of the fruitlessness of membership. While indeed complex and challenging, the paper seeks to present the situation of Colombian membership in more nuanced light. [ABSTRACT FROM AUTHOR]

Equity is a priority for the development of education policies in Latin America and the Caribbean, whose intention is to contribute to the construction of fairer and more democratic societies in line with the 2030 Agenda. Tracing the path followed by national education policies, in terms of opportunities and challenges, has inspired this paper whose aim is to pinpoint the context and evolution of Colombia’s ‘Todos Aprender’ program (PTA) from an equity perspective. Using a public policy analysis methodology based on documentary review and scientific credibility criteria, the analytical hypothesis is that PTA, without being a public policy, has become a de facto public policy with an impact on improving the quality of learning of preschool and elementary school students. According to the following questions of analysis: What has been the meaning and context of PTA’s evolution? What actors have been involved in PTA during its years of implementation? What has been their role in terms of positions, interests, and tensions? PTA has attempted to provide institutional responses to the lack of quality and equity in education, with changing priorities depending on each political moment. Thus, PTA represents an adaptable reference with pedagogical power from public policy to promote preschool and elementary education in the face of the educational challenges of the 2030 Agenda, promoting actions in teacher training, educational innovation and research, and formative evaluation to promote successful learning for all.

Colombia is one of the most inequal countries in Latin America, which at the same time, is the most inequal region of the world. Even though this situation is discouraging it is not new, the difference lays on the importance that this situation has been taken in the political agenda in the nation, awakening multiple expectative between the citizens who has been the eternal losers: the poor. This paper focuses on the challenges that the new government of Gustavo Petro faces in matter of the inequality and poverty that affects over the half of the population in Colombia, at the same time provides a context of the Colombian case in the conjuncture of global and regional socioeconomic changes that incident on the chances of fulfill structural transformations at the social policy. Although this research acknowledges a large spectrum of inequalities existing in the territory (gender, generational, ethnic, racial) it focusses on the income inequality. This analysis takes place based on the data of specialized sources on the subject and the monitoring fluctuations of inequality in Colombia in the last decade. [ABSTRACT FROM AUTHOR]

Researchers and practitioners recognise the importance of context when implementing healthcare interventions, but the influence of wider environment is rarely mapped. This paper identifies the country and policy-related factors potentially explaining the country differences in outcomes of an intervention focused on improving detection and management of heavy alcohol use in primary care in Colombia, Mexico and Peru. Qualitative data obtained through interviews, logbooks and document analysis are used to explain quantitative data on number of alcohol screenings and screening providers in each of the countries. Existing alcohol screening standards in Mexico, and policy prioritisation of primary care and consideration of alcohol as a public health issue in Colombia and Mexico positively contributed to the outcome, while the COVID-19 pandemic had a negative impact. In Peru, the context was unsupportive due to a combination of: political instability amongst regional health authorities; lack of focus on strengthening primary care due to the expansion of community mental health centres; alcohol considered as an addiction rather than a public health issue; and the impact of COVID-19 on healthcare. We found that wider environment-related factors interacted with the intervention implemented and can help explain country differences in outcomes. [ABSTRACT FROM AUTHOR]

This paper is the result of research whose objective was to investigate the genesis of Library Parks as an expression of political and architectural discourse in Colombia. For this purpose, a methodology based on a comparative historiography of the phenomenon of libraries and educational buildings built in public parks as a government policy at the beginning of the 20th century, and later, in the interstice between the 20th and 21st centuries, is proposed. The conclusions show that, contrary to the general perception, the library park model is not an ex novo phenomenon of the contemporary world. In this sense, the results evidence not only the identification of a set of antecedent projects of this phenomenon, built between 1932 and 1940, but also a set of existing correlations between political and architectural discourses, as a predetermining reflection of a system of thought that gave rise to the library park model.

Background and aims: During the study of the bryoflora of Bogotá, individuals of Syntrichia papillosa were found in urban localities. The aim of this contribution is to confirm the presence of this epiphytic species to the Colombian flora. Materials and methods: Living plants and herbarium material from the Natural History Museum (BM), the New York Botanical Garden (NY) and Jardín Botánico José Celestino Mutis (JBB) herbaria, were analyzed. Recently collected specimens were deposited in JBB. Results: A conspectus of the morphological features of the species based on herbarium specimens are provided, along with morpho-anatomical photographs. Further, the presence of the species in different localities belonging to the area around Bogotá was confirmed. Conclusion: This paper confirms the presence of Syntrichia papillosa in the surroundings of Bogotá. This species is known from Asia, Australia, Europe, New Zealand, North America, Africa, Argentina, Bolivia, Brazil, Colombia, Chile, and Ecuador. Thus, the genus Syntrichia is represented in Colombia by eight taxa: S. andicola, S. bogotensis, S. breviseta, S. fragilis, S. kingii, S. lacerifolia, S. laevipila and S. papillosa.

Infrastructural design, transport and mobility policies are strong instruments for interpreting historical urban and regional transformation processes. The paper addresses the intercausalities between both of them. To do so, it briefly sketches debates on the causalities of transport infrastructure and urbanisation and the theory of technological politics, drawing attention to the relationship between transport infrastructure and politics, and how infrastructures and their techno-political frames include means of power and authority. From there, the paper moves to the debate on the relationship between social justice and transport, showing how transport systems embody social processes and social (in)injustice. The history of agrarian extractivism in the region of Urabá in Colombia serves as a case study. The paper shows how existing transport networks of the region of Urabá have supported the expansion of agrarian extractivist industries and more specifically the production of transport (in)justice. It explores the development of the infrastructural network, transport systems and urbanisation of this region from the early 1900s onwards. Results show how the actual agrarian extractivist industries of the region are causing huge challenges related to the overlapping of transport scales, congestion and risks of accidents in urban areas, and how actual transport dynamics in the region are affecting urban development, generating a high segregation characterised by uneven distributions of public services and transport infrastructures. The paper reveals that the existing transport developments in the region of Urabá have no support for local development and are mainly thought for the efficiency of agrarian extractivist industries over local economic development. Agrarian extractivism has been a consistent factor in the economic, political and social spheres, and since colonial times the appropriation of natural resources and the dispossession of territories has been omnipresent. This paper explores the historical role of transport in agrarian extractivism, the long-term impact of the prolongation of old mechanisms, and the interrelations of the latter with current urbanisation and development. It concludes that infrastructural developments in this region have supported agrarian extractivist industries, first in colonial times, but also more recently, showing the deep embeddedness of the relation between mobility and urbanity in the (agrarian extractivist) development history of this region.

Fiscal credibility plays an important role in creating favorable scenarios for investment and economic growth. Adequate management of public finances can be decisive in the perception of country risk and the attraction of foreign capital. The aim of this paper is to build a fiscal credibility index and evaluate its impact on investment expectations in Colombia for the 2005-2019 period. Using monthly data on fiscal credibility, investment expectations, and a set of control variables, estimates were made using OLS and GMM methods. Robustness tests were performed using impulse-response functions. The findings reveal that fiscal credibility directly influences the investment decisions of private agents, and that local interest rates and international volatility negatively affect investors' expectations.

Fipronil is an insecticide and acaricide widely used in agriculture and domestic animals worldwide. Ecotoxicology studies have shown that, even at the low concentrations used on target species, fipronil and its degradation products have a significant impact on non-target species, either by direct toxicity or indirect effects affecting the food chain. The negative effects of fipronil on non-target species of terrestrial and aquatic invertebrates and indirect effects on food chains have led to its use being banned or severely restricted in numerous countries, including all of the European Union, China, and the United States. Some of the species highly susceptible to fipronil are of great economic and ecological importance, including crayfish, brown shrimp, and bees. In particular, the impact on decimating bee hives worldwide is an example of fipronil´s undesirable effects on agriculture. Other species affected by fipronil -for which there are few studies- are biological predators of the same pests controlled by fipronil. Considering all the impacts on non-target species, the commercialization and indiscriminate use of fipronil in agriculture seem irresponsible. In Colombia, as of September 2021 and pressed by local beekeepers, the Instituto Colombiano Agropecuario (ICA) prohibited its use on avocado, coffee, citrus, and passiflower plantations. However, as long as its use is not prohibited in all agricultural applications, farmers could divert its use and continue using it in any other type of plantation. This paper describes the impact of fipronil on some of the beneficial invertebrate species of outmost economic and ecological importance. [ABSTRACT FROM AUTHOR]

This contribution offers the author's personal experience with a project that took place 25 years ago in Latin America. This was about Second Order Auditing in Colombia during the second part of the 1990s. This project was carried out at the Country's National Auditing Office (CGR), and was an application of the Viable System Model (VSM) and the Viplan Methodology to a National Context. It was an innovative project at the CGR, focused on Second Order Auditing, to improve communications within the fabric of the Colombian government. Its emphasis was building responsible trust between public enterprises, ministries and political agencies. Its emphasis was building communications between ministries and public entities, with the aim of increasing their effectiveness. At its core were methodological and epistemological developments. Key questions it attempted to answer were how to model the complexity of the enterprises and how to transform the auditors' views of their relations with people in public entities, from one focused on requesting information, to one focused on communications. Structural changes were proposed for the National Audit Office and state enterprises, and hundreds of auditors were trained, through epistemological methodological workshops, in second order auditing and the reports of their auditing were debated extensively in government and beyond. This paper finishes with a short discussion of these transformations in the light of organisational cybernetics and in particular of the Viable System Model. [ABSTRACT FROM AUTHOR]

This paper addresses the energy efficiency issue in household appliances, which has led to the establishment of policies at a global level in favor of setting minimum energy performance standards (MEPS), which guarantee end users are able to select more efficient equipment. The countries of the United States, Brazil, Mexico, Chile, and the Community of the European Union were taken as references to review their policies and implementation strategies, in order to be compared with the Colombian panorama (at the market, technical and political levels). This allows the establishment of common aspects and differences related to the determination of energy consumption, adjusted volume, and formalization of efficiency ranges, and in the specific case of domestic refrigeration. Managing to distinguish the most relevant aspects for the successful adoption of these policies in Colombia. It is evident that the implementation of these guidelines has a positive impact on the market of the countries and communities of reference. Similarly, the MEPS are shown as a mechanism to regulate energy consumption in the residential sector. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this paper is to analyze the role of the process innovation on export propensity in knowledge-intensive business services (KIBS) firms and non-KIBS firms in Colombia. Design/methodology/approach: For the empirical application, the authors use a unique primary data set drawn from the Global Competitiveness Project (GCP: www.gcp.org) that includes information for 57 Colombian KIBS for 2019. The authors use a binary choice model to test the proposed hypotheses on the relevance of KIBS and process innovation in explaining export propensity. Findings: The results showed a positive relationship between KIBS and business size with an export propensity, but this relationship is non-meaningful. Also, the findings showed a negative and non-significant relationship between a process innovation and business age with the probability to export. On the other hand, the evidence state that KIBS firms encourage the relationship between propensity to export and process innovation, which is to say that they are highly effective to increase the propensity to export. Finally, the industry increases the probability of export propensity. Originality/value: This study offers a new insight relating to KIBS, process innovation and their contribution to increasing export propensity. The findings of this paper offer relevant information to government policymakers to design strategies that promote export activity in Colombia. [ABSTRACT FROM AUTHOR]

The humanitarian crisis in Venezuela has caused the migration of millions of people towards several countries, a situation that has impacted Colombia in a special way since this is the bordering country with the greatest mobility. Among the immigrant population there is a wide portion of boys, girls, and adolescents representing a challenge to the government, to the educational establishments, and to the coexistence between Colombian and Venezuelan students in schools. This paper is focused on the identification, as perceived by teachers, of the educational conditions that allow or hinder the Venezuelan students to integrate into the Colombian educational system. The methodology was based on conducting mixed focus groups including teachers from educational institutions in Cúcuta and Bogotá, two Colombian cities involving a high concentration of migrant population. Among the most important conclusions achieved there is the identification of a series of factors that, on one hand, facilitate a proper acceptance at educational institutions but, on the other hand, there are difficulties related to the lack of tools that permit to face circumstances potentially generating conflictive situations. Some of such circumstances are xenophobe, strain situations between students, the need of establishing social links beyond the classroom, the lack of teaching tools and curricular innovations, the scarcity of institutional policies, and the existence of situations of vulnerability or risks affecting Venezuelan students.

Objective/Context: The year 2021 marked the 50th anniversary of the Regional Indigenous Council of Cauca (CRIC), the first organization established in Colombia to fight for territorial and identity rights of Indigenous Peoples. From a historical perspective and proposing an approach related to the concept of resistance, this paper focuses on how this latter has been expressed through this indigenous movement since its inception. Methodology: The information and reflections presented here are based on a corpus of bibliographical and documentary sources, as well as on a follow-up of the political mobilizations of indigenous peoples in situ, in the media, digital social networks, official minutes, and other statements. Conclusions: The analysis reveals the persistence of indigenous resistance and an expansion of the project that accompanies it, from a struggle for land and territory to efforts carried out along with other actors and social organizations to create a "better world." Originality: The originality of the article consists of an analysis of the political dimensions of the resistance of Indigenous Peoples, which are still little known. In addition, it offers a novel approach to stress the intersection of (sub) national and global dynamics in which the demands of Indigenous Peoples and issues related to Colombia's society and the whole world converge.

The long-lasting consistency of a regulatory framework is essential for the proper functioning of incentives, particularly in industries such as electricity generation, with high sunk costs where different schemes have been developed to guarantee a long-term supply. In this respect, the instability of the regulatory framework can both impede the proper functioning of such incentives and, on occasion, violate the legitimate expectations of the agents involved. The purpose of this paper is to study the stability of the regulatory framework in terms of the long-term incentive mechanism for power generation applied in Colombia, known as "Cargo por Confiabilidad." The findings of this paper suggest the independence of the regulatory agency must be strengthened and that the instability of the regulatory framework has generated redistributions of income among agents. This study observes that among these agents, the best-organized pressure groups benefit the most from such a redistribution of incomes. [ABSTRACT FROM AUTHOR]

Objective: The aim of this paper is to present a review of specific cases that reported lead concentrations in blood, objects, food, soil, bioindicators, air, and water in specific places in Colombia and evaluate the reported concentrations against target values. Materials and Methods: A systematic qualitative literature review of publications between 1995 and 2019 was done; using Boolean operators 1571 papers were identified, to which 3 inclusion and 4 exclusion criteria were applied. A total of 57 studies met the defined criteria. The reports in these studies were geolocalized and compared with acceptable values. Results and Discussion: Results suggest that lead is present in all environmental matrices, widely distributed in the Colombian territory, and that 72 % of the cases exceeded regulation limits. The percentage of noncompliance per environmental matrix was 89 % for blood samples, 71 % in food, 63 %, in soil, 89 % for bioindicators, 60 % for air, and 55 % for water. Conclusion: These results show that lead pollution is a large-scale problem in the country, more systematic studies are needed, and control measures, policy-making and regulatory updating should be pursued.

This paper presents a proposal for incorporating educational robotics into primary and secondary education to support the Ministry of National Education's general guidelines for technology education in Colombia from various national and international approaches. The research is carried out with a mixed-method and divided into the documentary, descriptive, analytical, and projective phases. The paper contains three sections: a conceptual review of educational robotics; its importance, based on scientific literature and applied programs internationally and nationally; and finally, the treatment of robotics from different knowledge approaches, perspectives, and dimensions. We noted a growing tendency to introduce robotics education in private and public schools, focused on the "use of free time." Therefore, we propose designing a spiral curricular model with four complexity levels relevant to the principles of meaningful and inclusive learning, per the current needs for and cutting-edge knowledge of science and technology education.

This paper presents a growth strategy that, modifying the distribution of income in favor of wage earners, allows boosting aggregate demand, productivity and employment. This proposal is essential for the achievement of the Sustainable Development Goals, especially those related to growth, innovation, employment, and distribution in Colombia, opposed to the model that has historically been applied and that implied an exclusive growth. To build this alternative vision, the paper presents a renewed theoretical proposal based on the concept of inclusive growth, and by means of Structural Equations Modeling (SEM), the hypothesis that the concentration of the productive structure generates distortions in the economic, innovation process and job creation. This makes necessary to adopt policies focused on increasing productivity and diversifying the productive structure. [ABSTRACT FROM AUTHOR]

At the intersection between sociology, anthropology and law, this article analyses the various legal instruments for the protection of the natural environment in Colombia. In their application, these instruments have produced a range of conflicts, stemming from ecosystem conservation strategies, legal complexity and disregarded social realities. Based on the analysis of the situation in the Ciénaga Grande de Santa Marta, the paper argues that the interaction of the different environmental protection and conservation measures is generating a tension between guaranteeing protection for human rights, people's well-being and the ecosystems themselves.

Background: Abusive and disrespectful treatment of women during childbirth is a critical global issue that threatens women's sexual rights and reproductive rights and access to quality maternal care. This phenomenon has been documented in Colombia. However, little emphasis has been placed on identifying the drivers of and potential interventions against disrespect and abuse against particularly vulnerable populations in the country, including internally displaced indigenous women.Methods: This report is a sub-analysis of a larger project. Semi-structured interviews were conducted with indigenous (Embera) women with childbirth experience (n = 10), maternal healthcare workers (n = 6), and community stakeholders (n = 5) in Medellín, Colombia. Qualitative analysis techniques, consisting of inductive and deductive approaches, were used to identify and characterize the drivers of disrespect and abuse against indigenous women during childbirth and points for intervention. Existing frameworks were adapted to thematically organize drivers and potential solutions into four interrelated subsystems: individual and community factors, clinician factors, facility factors, and national health system factors.Results: Participants highlighted disrespect and abuse as stemming from (within the individual and community level) its normalization, lack of autonomy and empowerment among indigenous women, lacking antenatal care, (within the clinician level) prejudice, linguistic or cultural barriers to communication, lack of understanding of indigenous culture, medical culture and training, burnout and demoralization, (within the facility level) inadequate infrastructure, space, and human resources, and (within the national systems level) lack of clear policies and the devaluing of respectful maternity care. They called for interventions specific to these drivers, grounded in dignity and respect for indigenous culture.Conclusion: This paper expands upon the growing literature on global mistreatment during childbirth by highlighting drivers of mistreatment and identifying points for intervention in a previously unstudied population. Our data show that indigenous women are especially vulnerable to mistreatment due to cultural and linguistic barriers and prejudice. Broad and meaningful action is urgently needed to realize these women's rights to respectful maternity care. Interventions must be multifaceted and locally specific, taking into account the needs and wants of the women they serve. [ABSTRACT FROM AUTHOR]

This paper explores in detail the transfer and investment components of the General Budget of the Nation, whose composition is complex to evaluate due to the nature and variety of its items. For the study of these items, the literature on the political economy of the budget and the budget process in Colombia is considered. The transfer and investment items represent about 60 % of the General Budget and have great inflexibility of public spending, due to the diversity of appropriations with legal backing, especially in the transfer's item. The investment is made up of a wide range of social programs, subsidies, and infrastructure projects, which in some cases correspond to commitments acquired in previous terms, through the so-called future terms. The rigidity of the budget deepens with the frequent approval of laws that generate additional spending on a temporary or permanent basis. [ABSTRACT FROM AUTHOR]

The purpose of this work is to explore the role of violent crime on adolescent fertility choices. It reviews the hypothesis that violent crime shortens life expectancy, which leads individuals to make earlier decisions about childbearing. We model the adolescent fertility rate (AFR) for the 10-14 and 15-19 years age groups separately. We use a panel data set for Colombia at department level from 2003 to 2014, using Arellano-Bond estimator with department fixed effects. The empirical findings suggest that crime has a positive effect on AFR among adolescent aged 15-19, and is statistically significant at 10%. The results of this paper contribute to explaining the connection between crime and fertility choices in Colombia. It provides further insight into the different factors affecting AFR, and stimulates public debate on the need to strengthen the country's institutions and to ensure access to quality education and the promotion of early interventions programs.

This paper examines social, cultural and religious factors that affect the implementation of international humanitarian law concerning dead and missing persons in non-international armed conflicts. To this end, the behaviour of both armed groups and civil society is studied. The argument made in the paper is that in some cases endogenous and exogenous systems of value (social, religious and cultural understandings), operating within the logic of armed non-State actors and within local communities, should be considered by policies concerning the search for missing persons. The Colombian armed conflict is used as case study; the social, cultural and religious practices of the National Liberation Army and the Revolutionary Armed Forces of Colombia – People's Army are analyzed as examples. Likewise, social and cultural values within affected populations can impact on post-conflict mechanisms agreed upon by the parties concerning the search for missing persons, and vice versa. Consequently, customs and traditions such as the "adoption" of unidentified buried people by local communities (social resignification of the dead) and the practices of indigenous communities are reviewed in order to establish a holistic framework.

The aim of this paper is to estimate the impact of price and oil production shocks on macroeconomic variables such as public debt, real exchange rate, and Colombian economic activity. This country depends to a large extent on oil exports, which could lead to different obstacles in macroeconomic management when prices and oil production record fluctuations. The paper first describes the importance of oil in Colombia, which went from being a completely-importing country in 1976 to an oil-exporting economy in 1986. The empirical analysis uses a time-varying vector autoregressive methodology, which assumes that the relation between prices and oil production with macroeconomic variables changes dynamically. The results confirm that there are different stochastic volatility patterns of the variables included in the model. According to the impulse response functions, positive oil price shocks did not cause significant effects on the real exchange rate or on government debt. However, the negative price shock in 2015 led to a real depreciation and an increase in public debt. [ABSTRACT FROM AUTHOR]

Economic growth is not always related to social welfare. Therefore, this paper takes the case of the Colombian economy that has a strong dependence on commodity exploitation to identify the impacts of different commodities such as oil, coffee, coal, and nickel over economic variables. The results show that the increase in prices of commodities generates significant impacts on economic activity in variables such as GDP and investment. Also, there are no significant impacts on variables that provide welfare to individuals as total consumption or the unemployment rate. [ABSTRACT FROM AUTHOR]

Previous research shows that irregular immigration can worsen perceptions of security. However, the real effect of irregular immigration on crime rates remains unknown. In this paper, we analyze the effect of irregular immigration inflows on crime in the recipient country. For this, we build a dataset of Venezuelan irregular immigration in Colombia and crime rates at municipal level between 2016 and 2018. Our specification is based on an IV strategy using the exogenous variation in distance to the borderline as an instrument for immigration. We find that the immigration shock caused a slight increase in two types of theft in the short run and no significative changes in violent crime. These results are robust when using different instrumental variables, applying special autocorrelation corrections, and including controls for police capacity. [ABSTRACT FROM AUTHOR]

This paper describes recentfindings on indigenous navigation in northern Colombia. Using the notion of "indigenous navigation" does not discriminate between pre-Columbian and historical times. This notion is very useful to see continuities in material culture. Since this is an ongoing research, historical, ethnographic and, to a lesser extent, archaeological sources are being used to understand the general elements of indigenous navigation in this part of the world.

The main objective of this paper is to analyze the effect of education, age, access to ICTs and physical and financial assets, as well as other personal and socioeconomic characteristics on the probability of being a formal or informal own-account worker. In order to achieve this purpose, information will be used at the urban level for the twenty-one main cities in Colombia from the Great Integrated Household Survey 2010 (GISH), by the National Administrative Department of Statistics (DANE) and the Colombian Longitudinal Survey of the University of the Andes 2013 (CLS). Based on these data, models that have a qualitative binomial and multinomial dependent variable are employed, correcting for selection bias. As main results, it was found that physical assets and access to credit have a positive marginal effect on the probability of being an own-account worker. On the other hand, the marginal effect of education was negative; the lower the educational level, the greater the probability of self-employment, especially regarding the informal work.

This paper characterizes the labor market of youth in Colombia from 2008 to 2017. We estimate labor market indicators for individuals aged between 14 and 28 years using microdata from Colombia's household surveys over the study period. Our estimates document the main patterns and trends in the labor market of youth in labor force participation, employment, unemployment, informality, and earnings. We compare these statistics with the same indicators of adults (individuals aged between 29 and 65 years), and explore differences in characteristics within youth such as gender, region, educational attainment, socioeconomic status (SES), and experience. Results indicate that participation rate of young Colombians have increased in recent years, but are mainly employed in low-quality jobs namely unsalaried and informal. We also document marked inequalities in labor market outcomes across youth characteristics. We provide a series of recommendations to guide future youth labor policy based on these estimates as well as the critical analysis of recent youth policies in Colombia. [ABSTRACT FROM AUTHOR]
