In 2009, through Court Order 004, the Colombian Constitutional Court declared that thirty‐four separate groups of Indigenous peoples were at risk of extermination due to armed conflict, and it ordered the government to protect them. In 2013, the court then ordered the government to prove its compliance with Order 004. The government did so through a complex documentation process. The production of documents in Colombia not only records compliance but also constitutes compliance even if the actions are limited. In this article, I examine the role of documentation in mediating legal protection in a violent context. How does a governmental report obscure a persisting threat that is mostly ignored? Using participant observation at the Colombian Interior Ministry on the government's response, I illustrate how this documentation converts ordinary governmental actions into restitution of rights and manufactures compliance via the display—and concealment—of numbers through a focus on aesthetics. This generates the effect of sufficient state response while obfuscating the failure to achieve any intended changes: a phenomenon that I term complying incompliantly. Transforming negligence into a proper response through a paper trail outsmarts auditing and maintains the state's legitimacy by normalizing the government's shortcomings. This article contributes to the analysis of the relationship among law, documentation, and transparency.

A corrigendum has been issued for an article published in Acta Paediatrica titled "Short-term neurological injury in newborn infants with overcooling in passive hypothermia and transferred to reference hospital in Colombia." The corrigendum addresses an error in Table 3, specifically regarding the use of symbols ">" and "<" in the group "Age of Onset of Hypothermia (hours)." The revised table rectifies the inaccuracies and ensures the precision of the findings. The online version of the article has been corrected accordingly. [Extracted from the article]

This study explores the impacts of armed conflict on women's sexual and reproductive health in Colombia, building on a reproductive justice perspective to analyse original interviews with stakeholders in healthcare, women's rights, and peacebuilding. The analysis reveals that war affects women's sexual and reproductive health in three ways, through violent politicisation, collateral damage, and intersectional dimensions. First, multiple armed actors have used women's health as an instrument in politically motivated strategies to increase their power, assigning political meaning to sexuality and reproduction within the context of war. Second, women's health has also suffered from secondary damage of conflict resulting from a decay in healthcare service provision and an unmet need for healthcare services among those affected by sexual and reproductive violence. Third, marginalised women have been particularly affected by a discriminatory nexus of poverty, ethnicity, and geographic inequality. The paper concludes with a reflection on the opportunities for reproductive justice in Colombia. [ABSTRACT FROM AUTHOR]

This paper explores the spatio‐legal dynamics of marine protected areas and their relation to socio‐environmental justice. It adopts a critical legal geography perspective to unpack ocean lawscape configurations triggered by territorial claims, the international mechanisms for maritime boundary‐making, and state sovereignty instruments. It is empirically focused on the Seaflower marine biosphere reserve, a protected area amid a geopolitical contestation between Nicaragua and Colombia in the southwestern Caribbean. By analysing its spatio‐legal history over two decades (2000–2021), the paper sheds light on the marine legalities of this region, which are often contradictory and overlapping. Focusing on the marine lawscape of Colombia, it explores the relationship between protected areas and marine territorialisation, also reflecting on the governance regimes' effects on indigenous livelihoods and marine biodiversity. The paper concludes that (i) marine protected areas are regularly being disrupted, re‐bordered, and reconfigured by the international ocean regimes governing the oceans; (ii) the link between the creation and management of marine protected areas and territorial jurisdiction compromises social and environmental justice, and (iii) inclusion of indigenous legalities might enhance equity and sustainability in ocean governance.

Considering the ongoing, record‐setting migration in the Global South, this paper explores the values, principles and ethical tensions of Venezuelan migrants in the informal economy of Colombia. We found that migrants frequently prefer to stay within the informal economy as a way of preserving their identities, values and principles, rather than adopting those of their new country. This choice sets up ethical tensions for the migrants and their host countries. Our analysis challenges the current policy goals of transitioning migrants from informal to formal economies as a mark of success and inclusion. Instead, we attempt to recognize the migrant voice and their agency capacity through our research using focus groups and applied thematic analysis (ATA) of popular music and narratives. Our findings broaden the understanding of why migrants choose to stay in the informal economy and challenge policy goals that focus on inclusion and integration of migrants into formal economy.

Background: Verbal fluency tests (VFT) are highly sensitive to cognitive deficits. Usually, the score on VFT is based on the number of correct words produced, yet it alone gives little information regarding underlying test performance. The implementation of different strategies (cluster and switching) to perform efficiently during the tasks provide more valuable information. However, normative data for clustering and switching strategies are scarce. Moreover, scoring criteria adapted to Colombian Spanish are missing. Aims: (1) To describe the Colombian adaptation of the scoring system guidelines for clustering and switching strategies in VFT; (2) to determine its reliability; and (3) to provide normative data for Colombian children and adolescents aged 6–17 years. Methods & Procedures: A total of 691 children and adolescents from Colombia completed phonological (/f/, /a/, /s/, /m/, /r/ and /p/) and semantic (animals and fruits) VFT, and five scores were calculated: total score (TS), number of clusters (NC), cluster size (CS), mean cluster size (MCS) and number of switches (NS). The intraclass correlation coefficient was used for interrater reliability. Hierarchical multiple regressions were conducted to investigate which strategies were associated with VFT TS. Multiple regressions were conducted for each strategy, including as predictors age, age2, sex, mean parents' education (MPE), MPE2 and type of school, to generate normative data. Outcomes & Results: Reliability indexes were excellent. Age was associated with VFT TS, but weakly compared with strategies. For both VFT TS, NS was the strongest variable, followed by CS and NC. Regarding norms, age was the strongest predictor for all measures, while age2 was relevant for NC (/f/ phoneme) and NS (/m/ phoneme). Participants with higher MPE obtained more NC, and NS, and larger CS in several phonemes and categories. Children and adolescents from private school generated more NC, NS and larger CS in /s/ phoneme. Conclusions & Implications: This study provides new scoring guidelines and normative data for clustering and switching strategies for Colombian children and adolescents between 6 and 17 years old. Clinical neuropsychologists should include these measures as part of their everyday practice. WHAT THIS PAPER ADDS: What is already known on the subject: VFT are widely used within the paediatric population due to its sensitivity to brain injury. Its score is based on the number of correct words produced; however, TS alone gives little information regarding underlying test performance. Several normative data for VFT TS in the paediatric population exist, but normative data for clustering and switching strategies are scarce. What this paper adds to existing knowledge: The present study is the first to describe the Colombian adaptation of the scoring guidelines for clustering and switching strategies, and provided normative data for these strategies for children and adolescents between 6 and 17 years old. What are the potential or actual clinical implications of this work?: Knowing VFT's performance, including strategy development and use in healthy children and adolescents, may be useful for clinical settings. We encourage clinicians to include not only TS, but also a careful analysis of strategies that may be more informative of the underlying cognitive processes failure than TS. [ABSTRACT FROM AUTHOR]

This review article presents the results of an exploratory study for illuminating the state of the research concerning public policy in Colombia. A core assumption of the project is that the national capacity (intellectual capital) for producing relevant and thorough research in public policy, theory and practice, is a key element for the quality of its democracy and the sustainability of the system. A systematic documentary review of the research papers produced between 2008 and 2018 was conducted, spanning a total of 1010 papers. The results point to the relevance of continuing this type of study within Colombia and to the need of involving all the stakeholders in a dialogue about how to improve the country's capacity to design, implement, and evaluate sound public policies.

Adolescent and young women face grave nutrition challenges, but limited evidence exists on solutions to improve their diets. Action‐research was done over 3 years (2020–2022) in secondary cities of Colombia (Medellin) and Vietnam (Thai Nguyen) to identify nutrient deficits in adolescent and young women diets; elaborate food‐based recommendations to improve their nutritional status using Optifood linear programming; and engage respondents in incorporating suggested recommendations to their diet using a Social Innovation Challenge approach. A total of 1001 respondents were interviewed in Vietnam, 793 in Colombia. The probability of nutrient inadequacy in both locations was highest for iron and calcium, followed by the risk of deficiency for several other vitamins and minerals. Social Innovation Challenge teams (11 in Vietnam, 9 in Colombia) were created and supported in developing solutions to improve diets and tackle those deficiencies. Awards and resources were transferred to the most promising solutions to enable their implementation. Pre/post measurements of the interventions' impact using the Global Diet Quality Score as outcome metric showed significant improvement in the diets of Challenge participants. After introducing a series of companion articles that offer detailed results on those various steps, this paper draws strategic lessons from an action‐research perspective. [ABSTRACT FROM AUTHOR]

This paper studies the connections between the expansion of mining capital, speculative forms of land grabbing and agrarian transformation. It is argued that in periods of commodity boom, the landowning rural elite benefits from mining through speculative land deals with mining companies. They act as 'land brokers' for the mining firms, helping them to overcome a significant barrier to land accumulation through the de facto abolition of landed property. The analysis is based on a qualitative case study on the expansion of coal mining in central Cesar in northern Colombia. To develop my arguments, I refer to the concept of accumulation by dispossession as defined by Michael Levien, and historical materialist approaches on rent, and speculative land dispossession. In addition, I use concepts developed for studying coercive land grabbing and agrarian elite participation in armed conflicts to analyse the mechanisms applied to (coercively) acquire rights to land. It is concluded that with high global prices for minerals, metals and fossil fuels, the expansion of mining in the countryside fosters a process of agrarian change through land speculation that is articulated in a reconcentration of landed property, a re‐strengthening of the rural landowning elite and the dissolution of peasant agriculture.

Some literature on public sociology conceives of students as a public rather than potential or real practitioners of this type of sociology. There is a dearth of texts reflecting on graduate student training in public sociology and the trade‐offs they face. In this paper, I engage in a reflexive account of my experience doing public sociology, as I partnered with nonprofits to conceptualize, research, and write a report on the effects of stripped citizenship in Colombia after a mistaken administrative decision deprived 40,000 mostly binnational Venezuelan‐Colombians of their nationality in that country. This report has served as part of strategic litigation and to raise public awareness of the harmful policy. I argue that three things are key for graduate students to engage in public sociology and have been overlooked. First, training in public sociology, especially training with elements of apprenticeship, can develop the publicly engaged sociological imagination and toolkit, which is key to identifying opportunities for interventions in the midst of fieldwork, and models for interventions. Second, support from established professors. And third, local, contextual knowledge is indispensable. I also discuss ways to offset some of the trade‐offs that graduate students are likely to face when doing public sociology. [ABSTRACT FROM AUTHOR]

Several repercussions of the COVID‐19 pandemic and its subsequent isolation period have been reported worldwide. In this paper, we analyze the behavioral and emotional effects of 1 year of coronavirus‐related lockdown in Colombia. A cross‐sectional correlational design was used on a sample of 1853 participants from different regions, and with different levels of education, income, and employment situations. We applied the fear of coronavirus scale, the use of preventive behaviors scale, and a scale to measure pleasant and unpleasant emotions based on the circumplex model of affect. Our data shows that women, participants who were unemployed during the lockdown, and participants that study or work in legal, computational, or related fields, have been more affected in terms of unpleasant emotions. In addition, we observed a trend towards a relation between higher income and educational levels with lower degrees of fear, higher degrees of pleasant emotions, and a greater use of preventive behaviors related to the pandemic.

Forest landscape restoration (FLR) is the intentional intervention in the forest landscape to recover biological diversity and ecosystem functions, improving human well‐being in altered landscapes. The general objective of the present study was to understand the state of the art of research that potentially contributes to FLR practices in the Amazon. We carried out a comprehensive literature review using the Web of Science platform, considering papers published between 2000 and 2020 to understand the state of knowledge on restoration strategies that support FLR in the nine Amazonian countries and the nine states of the Brazilian Amazon. We selected 362 articles that met our inclusion criteria after analyzing 1,205 articles. We found that Brazil, followed by Peru, Colombia, and Ecuador, has the largest number of published articles on FLR. Agroforestry (37.88%) and natural regeneration (30.35%) were the most common FLR strategies across all countries and Brazilian states. Most studies investigated ecological functioning (33%), vegetation structure (31%), and tree diversity (15.5%). Forest restoration strategies (forest plantation, natural regeneration, or silviculture) are reported in most studies (57.23%), in comparison to restoration strategies of agricultural lands (agroforestry systems or improved fallow; 42.77%). We found an increase in publications describing restoration strategies over time in the Amazon, especially from 2012 onwards, with a peak in 2018. Future studies in the Amazon region should address socioeconomic issues and expand the geographic scope within the Amazon, as well as the FLR strategies and the ecosystem attributes investigated.

In this paper, I argue that the cumulative effects of coercive and indirect labour discipline enable firms to reorganize production. Through a historical analysis of the palm oil industry in northeastern Colombia, I identify changing forms of value chain governance in relation to transformations in labour control regimes. The combined effects of multiple labour control strategies have weakened labour power and workers' overall possibilities to shape value chain governance. In this case, labour coercion directly diminished workers' associational power and enabled labour flexibilization in the industry, limiting workers' structural power. A dialogue between the Global Value Chains framework and Critical Agrarian Studies, with a focus on labour regimes, highlights that labour flexibilization can build on past instances of coercive control to transform the structure of a value chain. This research illustrates that coercion is not necessarily "extra‐economic" but is often intrinsic to the organization of the global economy. [ABSTRACT FROM AUTHOR]

Within feminist geography, there is a growing consensus on the need for research to contribute to social change and transformation beyond the academy, and increased emphasis on the co‐production of impact. In this paper I critically reflect and report on how I co‐produced impact with a participatory audio‐visual research project, conducted in collaboration with women in Bogotá and Medellín and researchers and filmmakers based in the UK and Colombia. I focus particularly on co‐producing 'impact‐in‐process', which builds participants' capacities, creates spaces of reciprocal learning and increases participants' confidence and sense of ownership both during and beyond the research process. Yet, while co‐producing impact‐in‐process benefits research participants and has the potential to contribute to social change and transformation, this form of impact is rarely recognised as such.

In this paper, radial vibrations of a fluid‐filled poroelastic cylindrical bore saturated with two immiscible fluids of infinite extent are investigated. By considering the stress‐free boundaries, the frequency equation is obtained. Particular case, namely, fluid‐filled poroelastic cylinder saturated with single fluid is discussed. In both cases, phase velocity is computed as a function of wavenumber for different porosity values. The parameter values of Columbia fine sandy loam saturated with air‐water mixture are used for the numerical evaluation. The numerical results are presented graphically and then discussed. Wave propagation in a fluid‐filled borehole embedded in an infinite poroelastic medium is of great importance due to its various applications. Bore hole studies are of great help in exploration of oils, gases, and hydro‐carbons. This interest is strongly linked to the oil industry and the need to estimate the fluid mobility in reservoirs. Beyond the scope of geophysical applications, the understanding of wave propagation in cylindrical poroelastic structures is of great importance in the areas of non‐destructive testing, Mechanical Engineering and Civil Engineering.

This contribution explores processes of political class formation in peasant autonomy movements. The paper is based on a comparison of two peasant autonomy movements emerging from diverse agrarian structures and looks at how each movement emerged and developed. It argues that variations in class bases, cultural traditions and political histories shape the different ways autonomy is conceived and practised between peasant movements. The political expressions of autonomy struggles can be very diverse, ranging from poverty‐driven survival strategies to politicized socio‐territorial movements. The paper also highlights three main tensions in the question of autonomy for peasant movements: (1) struggles for autonomy do not involve a straightforward withdrawal from commodity markets, but also seek greater control over the terms of integration into markets; (2) states are still central focal points for the demands and tactics of autonomy struggles, and states still play an important role in allocating resources and co‐opting peasant movements; and (3) the strategy of autonomy alone is insufficient for building counter‐hegemonic movements. Leadership strategies are critical in shaping the political direction of autonomy movements. [ABSTRACT FROM AUTHOR]

In this paper I analyse how the gradual reduction of research funds in Colombia can interrupt a key process in the generation of solutions to global urban problems. I draw on a bibliometric analysis to show that research funding flowing from North to South has created collaborations between researchers from North and South that have led to a better and more comprehensive understanding of the challenges facing cities around the world. To conclude, I propose four options to counteract these trends towards lower research funding. [ABSTRACT FROM AUTHOR]

The paper presents data on the U–Pb chronology of detrital zircon grains and radiogenic isotopic composition (87Sr/86Sr, ɛNd) from the Proterozoic clastic successions of the Garhwal‐Kumaon Lesser Himalaya representing the extended northern Indian cratonic margin, NW India. The Proterozoic Lesser Himalayan Basin in Garhwal‐Kumaon Himalaya is divided into two sectors, namely, Inner Lesser Himalaya (ILH) and Outer Lesser Himalaya (OLH) by a tectonic boundary, namely the Tons Thrust (TT). Age distribution from inner and outer sectors of the Lesser Himalaya shows that the U–Pb chronology of most of these zircons provides Palaeoproterozoic (between 1.6 and 1.8 Ga) to Neoproterozoic (800 Ma) ages. The age data suggest sedimentation of the Rautgara Formation (Damtha Group) of ILH continued till the Neoproterozoic (~850 Ma), which was earlier regarded as ≤1.6 Ga. Tracking the detrital U–Pb zircon ages in the near adjacent cratonic parts point towards Aravalli Orogen as the major source region. Whole‐rock ƐNd(0) values for ILH rocks range from −37.6 to −14.6 and for OLH it ranges from −19.6 to −6.7. More negative ƐNd values along with dominance of Neoarchean‐Palaeoproterozoic ages in ILH indicates supply from more evolved protolith or recycled sources and less negative ƐNd values with major Neoproterozic zircon ages from OLH supports for less evolved source rock. The change from more negative ƐNd to less negative ƐNd values progressively upward the stratigraphy can be due to a shift in source with time. Both U–Pb zircon and ƐNd supports for a continuous sedimentation model, rule out the presence of ~500 Ma unconformity within the LH and argues for separate evolution of the Lesser Himalayan Basin on the trailing edge of the extended north Indian craton in "Columbia" configuration.

This contribution aims to explore the potentials and pitfalls for the emergence of a popular agrarian movement capable of offering a progressive alternative to the far‐right. Taking the case of Colombia's national agrarian strike, the paper argues that food sovereignty can offer a mobilizing framework for a multiclass, antineoliberal agrarian coalition. However, the possibilities for building a counter‐hegemonic movement should be taken with more caution. An examination of the class differentiation between and within campesino movements reveals how the interests of certain groups may be prioritized over others. While agrarian populism may offer an important political strategy for building coalitions and framing demands, a closer class analysis points to limits to its transformative potential.

Background: Small private online courses (SPOCs) are one of the strategies to introduce the massive open online courses (MOOCs) within the university environment and to have these courses validates for academic credit. However, numerous researchers have highlighted that academic dishonesty is greatly facilitated by the online context in which SPOCs are offered. And while numerous algorithms have already been proposed, no research has been performed on how to transfer this information to instructors, so that they can intervene and decrease the prevalence of this issue. Objectives: In this article, we present a qualitative evaluation of a tool for detecting and monitoring students suspected of academic dishonesty in SPOCs in Selene, a Colombian instance of Open edX. Methods: The evaluation was carried out through semi‐structured interviews with four instructors who taught SPOCs with academic recognition at the University of Cauca. Results: The evaluation results indicated that participants found the dashboard reliable and appropriate to detect academic dishonesty behaviours in order to intervene in these cases. Implications: But interventions are difficult to systematise, need an institutional policy, and there is uncertainty about whether these interventions can actually contribute to decreasing academic dishonesty. Lay Description: What is currently known about the subject matter: There are studies that detect academic dishonesty behaviour through webcams in massive open online courses (MOOCs).There are studies based on Learning Analytics techniques for the detection of academic dishonesty behaviour in MOOCs.There are dashboards for monitoring students' learning activities in online courses. What their paper adds to this: An algorithm for real‐time detection of academic dishonesty behaviour in small private online courses (SPOCs) with academic recognition is presented.A dashboard for the visualisation of students' academic dishonesty behaviour in SPOCs is presented.A qualitative evaluation of a dashboard for the detection of academic dishonesty in SPOCs with academic recognition is presented. Implications of study findings for practitioners: Our work opens an avenue for exploration of different ways to detect and follow up on academic dishonesty in online courses.Implies that trainers should have a basic knowledge of data analysis.

Summary: Tropospheric attenuations can be significant in the millimeter wave (mmWave) frequency bands; hence, accurate prediction modeling of tropospheric attenuation is important for reliable mmWave communication. Several models have been established by the International Telecommunication Union (ITU), yet estimation accuracy is limited due to the large spatial scales used for model input parameters. In this paper, we address this and apply local precipitation data to analyze tropospheric attenuation statistics and compare to results when using ITU regional input rain data. Specifically, tropospheric attenuation is predicted via simulations using the ITU method at 30, 60, and 90 GHz in four distinct geographic locations with different climate types. From our simulations, we gather statistics for annual average rain attenuation, worst month rain attenuation, and rain attenuation per decade. Our results indicate that when using local measured rain data, for 1 km link distance, mean rain event attenuation increases from 0.5 to 2 dB. Local rain data yield larger attenuations at essentially all percentages of time not exceeded (essentially corresponding to all probability values): for example, for 0.1% of time not exceeded, in Columbia, SC, rain attenuation for 30 GHz frequency increases to 9 dB with local rain data, compared to 5 dB with ITU's regional data, corresponding to rain rates of 38.2 and 17.5 mm/h, respectively; at the same probability and location, the 90 GHz attenuation increases by 10 dB, from 10 to 20 dB when local rain data are used. Fog attenuations are also appreciable, reaching 8 dB for the 90 GHz frequency. Moreover, for the example locations, peak rain attenuations have increased at a rate of approximately 2 dB/decade over the past 50 years. Our results indicate that actual tropospheric attenuations may be substantially larger than that predicted by the ITU model when using regional rain rate data. [ABSTRACT FROM AUTHOR]

This paper investigates the factors that determine survival migrants' intention to stay in their host country, using a survey of Venezuelan migrants in Colombia and analysed by means of a binary regression model. A theoretical framework that explains the intention to stay was derived from the theory of return migration and confirmed the importance of both meso‐level and macro‐level factors in migrants' intention to stay. A macroeconomic comparison confirmed that macro‐level factors played a role in the decision to migrate and stay. With respect to meso‐level factors, we found that survival migrants' intentions deviate from those of voluntary migrants since ties to their home country were not significant influences on their intention to stay. In contrast, factors that strengthen or weaken structural integration and ties to the host country were often highly significant, as were factors that influenced survival migrants' knowledge of the host country.

Given the rise of satellite television, radio telescopes in the Ku‐band (12–18 GHz) constitute a potential alternative to introduce low‐scale astronomical observatories and amateur astronomers to radio astronomy. In this paper, we show a methodology for the calibration of Ku‐band radio telescopes and the evaluation of the techniques used for the observation of celestial bodies in this frequency range. To reduce the pointing error, we present a method of observation through matrix windows around the Sun. By observing the solar transits, our methodology allows to determine the system temperature, the beamwidth, the gain, the effective area, and the efficiency of the radio telescope. In addition, we developed the Compact Radio Telescope (CRT) software, designed to perform the calibration, and carry out observations. We tested our methodology with the Ku‐band radio telescope of the Observatorio Astronómico of the Universidad Tecnológica de Pereira (OAUTP), Colombia. After observing the Sun and the Moon, we obtained a brightness temperature of 8,600 ± 800 K and 240 ± 50 K, and radiation fluxes of 2,970,000 ± 690,000 Jy and 55,000 ± 10,000 Jy, respectively. These observations demonstrated the usefulness of our methodology and CRT software in the calibration of compact Ku‐band radio telescopes for the observation of celestial bodies in radio waves.

In most Latin American countries, there are significant numbers of missing people and forced disappearances, over 120,000 in Colombia alone. Successful detection of shallow buried human remains by forensic search teams is difficult in varying terrain and climates. Previous research has created controlled simulated clandestine graves of murder victims to optimize search techniques and methodologies. This paper reports on a study on controlled test site results over four simulated dismembered victims' clandestine graves as this is sadly a common scenario encountered in Latin America. Multispectral images were collected once post‐burial, electrical resistivity surveys were collected 4 times, and ground penetrating radar (GPR) surveys were collected three times up to the end of the 371 day survey monitoring period. After data processing, results showed that the multispectral data set could detect the simulated clandestine and control graves, with electrical resistivity imaging relative high resistances over some of the simulated graves but not over the empty control graves. GPR results showed good imaging on the Day 8 surveys, medium imaging on the Day 294 surveys, and medium to good imaging on the Day 371 surveys. Study implications suggest that, while clandestine graves of dismembered homicide victims would likely result in smaller‐sized graves when compared to graves containing intact bodies, these graves can still potentially be detected using remote sensing and geophysical methods.

Melastomataceae is a megadiverse family with records of transitions from specialized to generalized pollination systems for several species. These transitions are associated with the colonization of new, unpredictable and/or impoverished pollinator habitats or habitats where specialized pollinators are scarce (e.g., in highland environments). The bee species diversity is low in highlands. Therefore, autonomous breeding systems such as apomixis and self‐pollination emerge in these environments. In this paper, we studied the floral traits associated with the generalization of pollination systems and registered the floral visitors of two species in the Colombian Andes: Miconia cataractae and M. elaeoides. We investigated the breeding system of M. elaeoides. Both species presented small flowers, short anthers of medium pore size, and nectar‐producing stomata on the base of the anthers. Miconia cataractae produced an average of 1.62 μl nectar/flower, a sugar concentration of 6.78%, whereas M. elaeoides produced 0.09 μl nectar/flower, a sugar concentration of 6.13%. We recorded a wide diversity of pollinators for both species, mainly insects from the orders Hymenoptera and Diptera. Miconia elaeoides presented a mixed breeding system and was also capable of setting fruits by apomixis. We conclude that flower and anther morphology, combined with nectar production, thus represent convergent traits resulting in a generalist pollination system shared by M. cataractae and M. elaeoides. Here, we presented the first generalist pollination system recorded for Miconia (and the Melastomataceae) in the Andes, the first report for a species from the small‐pored section Amblyarrhena, and the first report for a species from the large‐pored section Cremanium in Colombia.

In this paper, we propose Bayesian skew‐normal regression models where the location, scale and shape parameters follow (linear or nonlinear) regression structures, and the variable of interest follows the Azzalini skew‐normal distribution. A Bayesian method is developed to fit the proposed models, using working variables to build the kernel transition functions. To illustrate the performance of the proposed Bayesian method and application of the model to analyze statistical data, we present results of simulated studies and of the application to studies of forced displacement in Colombia.

Background and purpose: Perry disease (or Perry syndrome) is an autosomal dominant neurodegenerative disorder characterized by parkinsonism, neuropsychiatric symptoms, central hypoventilation, weight loss and distinct TDP‐43 pathology. It is caused by mutations of the DCTN1 gene encoding an essential component of axonal transport. The objectives were to provide the current state of knowledge on clinical, pathological and genetic aspects of Perry disease, as well as practical suggestions for the management of the disease. Methods: Data on new patients from New Zealand, Poland and Colombia were collected, including autopsy report. Also all of the published papers since the original work by Perry in 1975 were gathered and analyzed. Results: Parkinsonism was symmetrical, progressed rapidly and was poorly responsive to L‐Dopa; nonetheless, a trial with high doses of L‐Dopa is warranted. Depression was severe, associated with suicidal ideations, and benefited from antidepressants and L‐Dopa. Respiratory symptoms were the leading cause of death, and artificial ventilation or a diaphragm pacemaker prolonged survival. Weight loss occurred in most patients and was of multifactorial etiology. Autonomic dysfunction was frequent but underdiagnosed. There was a clinical overlap with other neurodegenerative disorders. An autopsy showed distinctive pallidonigral degeneration with TDP‐43 pathology. Genetic testing provided evidence of a common founder for two families. There was striking phenotypic variability in DCTN1‐related disorders. It is hypothesized that oligogenic or polygenic inheritance is at play. Conclusions: Perry disease and other DCTN1‐related diseases are increasingly diagnosed worldwide. Relatively effective symptomatic treatments are available. Further studies are needed to pave the way toward curative/gene therapy. [ABSTRACT FROM AUTHOR]

Purpose: Prescriptive and predictive analytics and artificial intelligence (AI) provide tools to analyze data with objectivity. In this paper, we provide an overview of how these techniques can improve nursing care, and we detail a quantitative model to afford managerial insights about care management in a Hospital in Colombia. Our main purpose is to provide tools to improve key performance indicators for the care management of inpatients which includes the nurse workload. Methods: The optimal nurse‐to‐patient assignment problem is addressed using analytics, lean health care, and AI. Also, we propose a new mathematical model to optimize the nurse‐to‐patient assignment decisions considering several variables about the patient state such as the Barthel index, their risks, the complexity of the care, and the mental state. Findings: Our results show that there are several processes inherent to compassionate nursing care that can be improved using technology. By using data analytics, we can also provide insights about the high variability of the care requirements and, by using models, find nurse‐to‐patient assignments that are nearly perfectly balanced. Conclusions: We illustrated this improvement with a pilot test that makes the equitable distribution of nursing workload the functionality of this strategy. The findings can be useful in highly complex hospitals in Latin America. Clinical Relevance: The proposed model presents an opportunity to make near perfectly balanced nurse‐to‐patient assignments according to the number of patients and their health conditions using technology.

Among geographers, recent focus on the illicit and illegal has tended to fall into two camps. Economic geographers focus on regimes of illicitness and corresponding production of specific forms of economic space; political ecologists and land change scholars, on the other hand, scrutinised how illicit commodity flows shape land and resource use, especially in the global South. This paper offers an initial integration of these two relatively separate subfields, specifically in terms of their complementary attention to uneven development. We use the concept of "global commodity chains" to explore the ways in which the regulation of agricultural commodities shapes how they are trafficked and embed in space, with particular attention to sites of international transshipment. When a commodity is illegal, spaces of transit take on significant analytical importance. As a heuristic, we present a comparative mapping of two agricultural commodity chains linking Colombia and the USA: coffee and cocaine. Their comparison highlights how "illicitness" fundamentally transforms cocaine's spatiality, requiring risk evasion that results in characteristically enlarged transit spaces and huge differentials between producer and consumer price. We show how rents circulate in those transit spaces, socially and ecologically embedding in diffuse, fluid networks with severe consequences for people and environments. We conclude with implications for work on illicit commodities and the collateral social and environmental harms they produce. [ABSTRACT FROM AUTHOR]

A growing body of evidence highlights that maternal and child nutrition programmes need to extend beyond the mother–child dyad by adopting a family systems approach, particularly in the Global South. Guided by a sociocultural and community psychology understanding of health, the paper explores factors identifying grandmothers as central resources for nutrition programmes. The study was conducted in a Colombian urban periphery applying a qualitative longitudinal design (prenatal and postpartum). It is based on interviews with adolescent mothers and mothers in their 20s (n = 35 at T1; n = 21 at T2), grandmothers (n = 15 at T1; n = 12 at T2) and community/public stakeholders (n = 17). Many of the participants live in low‐income households headed by grandmothers, who adjust feeding practices to the extent of their economic capacity. Findings reveal grandmothers play a central role in decision‐making and in enabling a holistic support system for the dyad. This is defined as grandmothers' scaffolding; it covers nutrition advice, breastfeeding and infant feeding, cultural practices, caregiving and maternal mental health. The study helps build the evidence‐base for the transferability of a family systems approach to Global South regions by using sociocultural and community psychology concepts to fortify the rationale for including grandmothers in maternal and child nutrition programmes. It argues for the need to continue raising the visibility of key actors like grandmothers and for nutrition programmes to align themselves more flexibly with the needs of families experiencing poverty.
