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]

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]

7. Spatial beta‐convergence forecasting models: Evidence from municipal homicide rates in Colombia.

HOMICIDE rates ,STANDARD deviations ,FORECASTING ,TIME series analysis - Abstract
The forecasting power of different methods is tested utilizing crime data for 1120 inland municipalities in Colombia. Using data from 2003 to 2018, five different forecasting methods are used: ETS, ARIMA, STAR, a classical beta convergence based model, and a spatial beta convergence model. First, it is shown that overall municipal crime disparities are steadily decreasing over time. This indicates that convergence and spatial effects are pivotal for the study of the dynamics of crime in Colombian municipalities. Time series cross‐validation for 4‐year ahead forecasts is implemented to assess the accuracy of all models. It is found that the STAR and the beta models have the lowest root mean squared errors. Therefore, as time goes by, space appears to play a more important role in the evolution of homicide rates. The paper concludes with some policy implications in terms of spatial effects and the mitigation of crime. [ABSTRACT FROM AUTHOR]

This paper discusses the limitations and risks associated with the use of output‐oriented measures to assess public school performance. In particular, it questions the capability of the performance measures set by external institutions, with respect to schools, to support sustainable educational outcomes. To this end, the 'street‐level bureaucracy' theory is used in the paper as a basis to analyse the behavioural distortions generated by perceived public service gaps at school level policy implementation. Such unintended behavioural effects are often a major cause of disappointing outcomes when test‐based accountability systems are adopted. In the second part of the paper, an insight model referred to a hypothetic medium‐sized public school located in a poor area in Colombia is used to illustrate how a feedback approach to school performance measurement can support decision‐makers to pursue sustainable education outcomes and to prevent behavioural distortions from perceived public service gaps at 'street‐level' policy implementation. This analysis outlines an alternative approach to school performance measurement that might help policy makers in extending the domain of governmental benchmarks to performance measures and collaborative efforts that reflect the challenges of holistic education in the context where public schools are located.

PARTICIPANT observation ,SOCIAL change ,HUMAN research subjects - Abstract
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.

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.

POLLINATION ,POLLINATORS ,FLORAL morphology ,MELASTOMATACEAE ,SELF-pollination ,NECTAR ,SPECIES diversity - Abstract
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 attempt to find existing linkages of financial literacy with indebtedness and wealth accumulation of households in Bogotá, the capital of Colombia. We analyze an econometric model where we regress a household's debt usage, cost of debt servicing, and wealth indicators against its financial literacy. Financial literacy is assessed according to the financial numeracy and money management skills of the head of households. Numeracy skills are found to have a positive correlation with the decision to use debt and have a mortgage and with the total number of lending sources, debt‐to‐income, and net worth. Money management skills decrease the household's likelihood of using all of the debt types considered in the analysis and increase with net worth. We also uncover important debt and wealth accumulation conducts closely tied to the city's economic stratification and the gender of the head of household. A number of public policy implications are derived from the results of the analysis. [ABSTRACT FROM AUTHOR]

This paper seeks to discuss the use of a participatory documentary process ( PDP) in human geography as a method of constructing critical visual information on territorial histories of dispossession. The process was also used to enhance social change both in conjunction with local communities and within the communities themselves. The project involved 14 local young participants and four professionals who collectively produced a documentary on the rural context of violence in La Toma District, Colombia. By enabling the reflections and intentions of young participants in the research process, PDP gave special value to their social and political commitment to supporting community social organisation, and provided fresh research insights into comprehending territorial conflict. The paper concludes that this method amplifies participatory and action research approaches in geography by producing knowledge that is academically and socially relevant. Such collective, emancipatory and anti-hegemonic visual representations and actions for social change in PDP are especially pertinent in spaces of conflict and violence. [ABSTRACT FROM AUTHOR]

The literature on evidence-based action in humanitarian crises commonly focuses on how inter-and non-governmental organisations can produce better knowledge and how this can be translated into improved programming. Yet, there is little recorded experience of, or concern about, how the beneficiaries of humanitarian relief can produce and use knowledge of their predicament. This paper is based on a case study of how the Liga de Mujeres Desplazadas, an internally displaced women's organisation in northern Colombia, employs proactively research-generated data to advance its own agenda in its interactions with donor bodies and the government. The paper finds that beneficiaries of humanitarian aid can, and do, use participatory research to advance their own ends in the legal and political spaces created around humanitarian crisis. However, their agency is limited by poverty, violence, and local balances of power. The paper concludes that beneficiaries' priorities in the production of data about humanitarian crises warrant further study. [ABSTRACT FROM AUTHOR]

Children born as a result of wartime sexual violence have not gained a place in the stories covered by the Colombian media. Based on an extensive content analysis (using the software MAXQDA 12) of newspaper articles published between 1990 and 2015, ethnographic content analysis, and drawing upon feminist critical discourse analysis, this paper explores how information about these children is presented as part of storylines that use the explanatory framework of sexual violence as a weapon of war. In those storylines, children emerge not as independent subjects but as part of social representations of female victims of wartime sexual violence and male perpetrators. [ABSTRACT FROM AUTHOR]

Building on an extensive literature review that included peer-reviewed publications, grey literature, national statistics, official reports, and regulations enacted by the Colombian government, this paper identifies opportunities, challenges, and constraints faced by solid biofuels production from energy crops in Colombia. Our findings suggest that the solid biofuels industry currently lacks policy regulations and an adequate research framework. The paper notes the industry's market potential and addresses its dependency on a legal framework, political willingness, and technological developments. The legal framework includes land ownership formalization, job regulations, and the definition of environmental and administrative permits. Political willingness relates to governmental policies and financial incentives based on environmental and sustainability criteria, which can make the sector competitive compared to other energy sources at the local and international market scales. The technological aspects include public and private support for research and development programs and a strategic analysis of industry-specific requirements for infrastructure, conversion, and transportation within a life cycle assessment framework. The preliminary land-use analysis suggests the potential availability of land for solid biofuels production in the Caribbean, Andean, Inter-Andean Valley, and Orinoco regions. Furthermore, the results show that solid biofuels production can potentially supply internal demand and play a role in international markets with strategic development and government support. © 2016 Society of Chemical Industry and John Wiley & Sons, Ltd [ABSTRACT FROM AUTHOR]

Latin America generates a low proportion of the references quoted in Medline, the most popular health-related literature search database in the world. This paper explores references from and about Colombia in Medline during the period 1987–1996. Topics addressed, patterns of authorship and research locations are established. The number of Latin American journals indexed in Medline has been progressively reduced during this 10-year period, with Colombian journals completely excluded since 1991. During this 10-year period, the total output of Colombian research institutions in foreign journals consisted of 531 articles, 41% (219) of which come from the four leading universities. These figures are substantially lower than those from other countries of the region such as Venezuela or Chile. Despite some governmental efforts, Colombia continues to have a low scientific output and has yet to attract the interest of foreign researchers. Alternatives for development of Latin American research and publications are offered. [ABSTRACT FROM AUTHOR]

This paper analyses the spatial and temporal patterning of Colombia's rural coffee, banana, and coca‐producing labour regimes. The violent labour repression and endemic crises of labour control characterizing these regimes challenge the market despotism paradigm that predominates in scholarly analysis of 21st century labour and agrarian struggles. Instead, I draw from early and later writings of Giovanni Arrighi and his collaborators to develop a new labour regime framework that is sensitive to the experiences of capitalist development in "hostile environments" (i.e., peripheral market conditions) and "hostile times" (periods of world hegemonic decline). In doing so, I highlight the deep social contradictions—crises, violence, and labour militancy—that result from processes of peripheral proletarianization and the ways that these contradictions were mitigated and/or exacerbated by the rise of U.S. global hegemony, Colombian developmental policy, and local agrarian struggle.

- Abstract
Latino women show lower incidences of breast cancer (BC) than non‐Hispanic whites. Large‐scale genetic association studies have identified variants robustly associated with BC risk in European women. We examine here the relevance of these variants to Colombian BC and possible interactions with genetic ancestry. Native American, European and African proportions were estimated for 1022 Colombian BC cases and 1023 controls. Logistic regression was applied to assess the association between 78 variants and BC risk and interactions between the variants and ancestry proportions. We constructed a multifactorial risk score combining established BC risk factors, associated risk variants and individual ancestry proportions. Each 1% increase in the Native American proportion translated into a 2.2% lower BC risk (95% CI: 1.4–2.9). Thirteen variants were associated with BC in Colombian women, with allele frequencies and risk effects partially different from European women. Ancestry proportions moderated the risk effects of two variants. The ability of Native American proportions to separate Colombian cases and controls (area‐under‐the‐curve (AUC) = 0.61) was similar to the discriminative ability of family history of BC in first‐degree female relatives (AUC = 0.58) or the combined effect of all 13 associated risk variants (AUC = 0.57). Our findings demonstrate ample potential for individualized BC prevention in Hispanic women taking advantage of individual Native American proportions, information on established susceptibility factors and recently identified common risk variants. What's new? Increasing Native American ancestry proportions are associated with decreasing breast cancer (BC) risk. This paper examines the contributions of genetic ancestry, established risk factors, and newly identified susceptibility variants to BC risk in a Colombian population with diverse proportions of European, Native American, and African ancestry. The authors demonstrate that individual ancestry proportions predict breast cancer risk in Colombia as accurately as established breast cancer risk factors. They also develop a multifactorial risk score and examine its potential for breast cancer risk prediction. The findings underline the relevance of considering genetic ancestry in the breast cancer care of Hispanic populations. [ABSTRACT FROM AUTHOR]

Recent years have seen an intense and critical debate about the impact of microcredit on entrepreneurial activities and poor households' welfare. This paper suggests that information asymmetries in the ex post loan arrangement between the microfinance institution and local borrowers could partially explain the limited impact of microcredit. The physical distance separating borrowers from the microfinance institution could be considered as a proxy of agency costs, increasing the costs of monitoring and easing moral hazard. The estimation of the effect of distance on the borrower's self-assessed outcome of a microcredit project in Colombia confirms the presence of moral hazard in the microcredit market, with agency costs increasing with geographical distance.

Abstract: Effectiveness trials of increasing childhood development interventions across low‐ and middle‐income countries have shown significant variability. The strength and consistency of benefits for children are dependent on program quality, and this requires paying attention to program implementation. In this paper, we summarize findings on program quality and teacher practices and perceptions for the aeioTU program, a center‐based Reggio‐inspired program in Colombia, now serving more than 13,000 children. The research found engaged, committed staff who valued the emergent approach and understood the children as requiring opportunities to express themselves, being the source for the curriculum, and having relationships with the materials around them. Although the average classroom quality was low in 2011, it increased significantly by 2014, particularly in the language and reasoning and interactions items. Indicator‐level analyses showed that higher‐order interactions and language processes were observed in a large proportion of classrooms by 2014. Teachers' self‐reports on the environment and their teaching and learning showed high levels of quality by 2013. These findings illustrate the significance of process data for program improvement, especially when a program is young. Program quality can be raised after teachers improve their skills, have experience enacting a curriculum, and after training has been strengthened in response to information, while simultaneously scaling up the program.

The Pacific region of Colombia, like many sparsely populated places in developing countries, has been imagined as empty in social terms and yet full in terms of natural resources and biodiversity. These imaginaries have enabled the creation of frontiers of land and sea control, where the state as well as private and illegal actors have historically dispossessed Afro-descendant and indigenous peoples. This paper contributes to the understanding of territorialisation in the oceans, where political and legal framings of the sea as an open-access public good have neglected the existence of marine social processes. It shows how Afro-descendant communities and non-state actors are required to use the language of resources, rather than socio-cultural attachment, to negotiate state marine territorialisation processes. Drawing on a case study on the Pacific coast of Colombia, we demonstrate that Afro-descendant communities hold local aquatic epistemologies, in which knowledge and the production of space are entangled in fluid and volumetric spatio-temporal dynamics. However, despite the social importance of aquatic environments, they were excluded from Afro-descendant's collective territorial rights in the 1990s. Driven by their local aquatic epistemologies, coastal communities are reclaiming authority over the seascape through the creation of a marine protected area. We argue that they have transformed relations of authority at sea to ensure local access and control, using state institutional instruments to subvert and challenge the legal framing of the sea as an open access public good. As such, this marine protected area represents a place of resistance that ironically subjects coastal communities to disciplinary technologies of conservation. [ABSTRACT FROM AUTHOR]

ABSTRACT This paper studies the socio-economic determinants of violence in the seven most important cities in Colombia. Derived from theories rooted in classic works, including Becker's paradigm, criminal inertia, social disorganisation, urbanism and strain, we formulate several hypotheses on the socio-economic determinants of violence. To test these hypotheses, a dynamic panel data analysis is employed. The analysis shows that cities' deprivation and high population density are strong predictors of homicide rates. Comparing the results among Colombian cities, we find support indicating that city-level homicide rates are influenced by the city's level of development. Moreover, we find evidence that economic growth, inequality, poverty and human capital influence violence in the cities studied, which could generate negative effects on the economic and social development of Colombia.

This paper focuses on three periods of stabilisation in Colombia: the Alliance for Progress (1961–73) that sought to stem the threat of communist revolution in Latin America; Plan Colombia and President Alvaro Uribe's ‘democratic security’ policy (2000–07) aimed at defeating the guerrillas and negotiating a settlement with the paramilitaries; and the current ‘integrated approach’, adopted from 2007, to consolidate more effectively the state's control of its territory.
1 The paper assesses the extent to which these stabilisation efforts have enhanced the protection of civilians and ultimately finds that in all three periods there has been a disconnect between the discourse and the practice of stabilisation. While they have all sought to enhance security, in actual fact, they have privileged the security of the state and its allies at the expense of the effective protection of the civilian population. This has not only led to widespread human rights abuses but also has undermined the long-term stability being pursued. [ABSTRACT FROM AUTHOR]- Published

As of 30 June 2006, more than 3.5 million Colombians are internally displaced persons (IDPs), the second largest IDP population in the world after that of Sudan. While most IDP studies treat the plight of internally displaced women (IDW) as an isolated phenomenon, this paper demonstrates that their situation reflects Colombia's chronic cultural, political and socio-economic crisis. This paper uses a sexual and reproductive rights framework to establish a connection between IDW and Colombia's culture of violence, discrimination and inequality. The effects of this culture of violence, discrimination and inequality are highlighted during a discussion of the rights to health, reproduction, privacy, physical integrity, education, and freedom from violence and sexual exploitation. This paper argues that a holistic understanding of Colombia's humanitarian emergency is essential to improving the lives of IDPs. It ends with some concrete, short-term recommendations to meet some of the needs of IDPs and other vulnerable populations. [ABSTRACT FROM AUTHOR]

The aim of this paper was to create a decision tree (DT) to identify personality profiles of offenders against public safety. A technique meeting this requirement was proposed that uses the C4.5 algorithm to derive decision rules for personality profiling of public safety offenders. The Mini-Mult test was used to measure the personality profiles of 238 individuals. With the test results as our database, a C4.5 DT was applied to construct rules that classify each profile into one of two groups, those without and those with records of offences against public safety. The model correctly classified 80% of the personality profiles and delivered a set of decision rules for distinguishing the profiles by group, and the principal personality profiles were interpreted. We conclude that DTs are a promising technique for analysing personality profiles by their offender or non-offender status. Finally, we believe that the development of a classifying model using DT may have practical applications in the Colombian prison system. Copyright © 2016 John Wiley & Sons, Ltd.

WOMEN in development ,EQUALITY ,SOCIAL conditions of women - Abstract
As a result of the United Nations Decade for Women (1976-1985) many member states of the United Nations in the South put in place some form of national machinery for the advancement of women. This paper considers that process, identifying three main phases. The first was heavily overlaid by the agendas of international development agencies and coincided with efforts to advance a "women in development" or WID agenda within international development cooperation. The second, explored here in relation to Colombia, saw a shift towards attempts to institutionalize gender awareness in development policy, the so-called "gender and development" or GAD approach. Against this background, the later South African experience is evaluated. It is argued that this potentially represents a third and distinguishable phase in the establishment of national machineries. Here structures were set up in the context of less aid dependence than many other countries and as a result of a process that was largely internally driven. Nevertheless, South Africa enjoyed tremendous support from international women's networks and lessons were learnt from past experience elsewhere, both positive and negative. The South African approach to advancing gender equality is arguably the most progressive to be found anywhere. What remains to be seen is whether it will be possible to implement, given the persistence of poverty and inequality nationally and South Africa's increasing identification with international neo-liberal agendas.

Body mass is one of the most important phenotypic attributes in animal ecology and life history. This trait is widely used in the fields of ecology and macroevolution, since it influences physiology, morphological functions, and a myriad of ecological and social interactions. In this data set, our aim was to gather a comprehensive bird and mammal body mass data set from northern South America. We report body mass, discriminated by sex, for 42,022 individual birds and 7,441 mammals representing 1,317 bird species (69% of Colombia's avifauna) and 270 mammal species (51% of Colombian mammals) from the Neotropics. The data were sourced from vouchers collected between 1942 and 2020 and from individuals captured and released at banding stations over the last two decades for birds (2000–2020) and the last decade for mammals (2010–2020), by 10 research groups and institutions in Colombia. This data set fills gaps identified in other similar databases, as it focuses on northern South America, a highly diverse Neotropical region often underrepresented in morphological data sets. We provide wide taxonomic coverage for studies interested in information both at regional and local scales. There are no copyright restrictions; the present data paper should be appropriately cited when data are used for publication. The authors would appreciate learning about research projects, teaching exercises, and other uses given to this data set and are open to contribute in further collaborations using these data.

The installation of cable cars as part of slum beautification projects has begun to circulate among politicians, planners and residents as a magical solution that offers social and economic integration to historically marginalized urban areas. This paper analyzes the way in which a cable car project became a fetish for the inhabitants, politicians and planners of Cazucá, a very deprived, abandoned and stigmatized area on the outskirts of Bogotá, Colombia. The highly positive value given to the cable car project must be understood within the specific local context without judging its 'false promises' a priori. The promise of the cable car in Cazucá reveals at least two crucial political reasons for the current potency of such projects: a complex history of political failures and the political value cable cars have acquired nationally and internationally. We analyze how, for both residents and politicians, the mere possibility of a cable car awakened long neglected desires for visibility and created new ones, such as those related to tourism. They see the cable car as an 'engine for social change', a way to ensure the commitment of national and international funds, and a venue to brand the city on a global scale. [ABSTRACT FROM AUTHOR]

In many Latin American cities, infrastructure was largely financed through development lending over the second half of the 20th century. Exacerbated by debt crises and currency devaluations, public utilities became holders of significant levels of negative value. This encouraged public debt financialisation in order to mitigate the effects of shifting interest rates and devaluation. For David Harvey, negative value is the hallmark of contemporary capitalism whereby one must produce, not for profit, but to retire debt. This statement can be applied to indebted utilities, in the sense that the focus of utility governance – and its relationship towards those dependent on it for services – becomes reoriented towards debt management – or governing by debt. Full‐cost recovery emerges in this context as a mechanism to pay down the infrastructure debt held by utilities, which quickly led to increasing levels of user indebtedness. Service disconnection and pre‐paid metering emerge as processes to recover this user debt by enforcing a culture of payment through service exclusion. In these ways, the responsibility for infrastructure debt 'trickles down' in small – but individually significant – amounts to persons and households, enrolling them in the logic of debt (re)payment. This paper examines these issues through a case study of urban infrastructure financing, debt, and tariffs in Medellín, Colombia from 1960 to 2013. [ABSTRACT FROM AUTHOR]

In Colombia, national policies and laws on the protection of vulnerable populations pay specific attention to the sexual and reproductive health needs and rights of internally displaced adolescents. This paper describes how a United Nations Population Fund (UNFPA)-supported programme (September 2000-August 2004) on the sexual and reproductive health of internally displaced adolescents contributed to restoring their dignity as a precursor to promoting their sexual and reproductive health rights. Different forms of the arts were used as basic techniques to discover their body and to provide sexual and reproductive health information and education. The arts were found to play a key role in restoring their dignity. Although dignity appeared to be a determinant of greater awareness of rights, it did not lead to increased empowerment with regard to rights. The availability of and access to sexual and reproductive health services remains a problem and displaced populations continue to have little or no power to hold their authorities accountable.

Species traits provide a strong link between an organism's fitness and processes at community and ecosystem levels. However, such data remain scarce for amphibians in the Neotropics. Colombia is the country with the highest number of threatened amphibians and the second greatest number of amphibian species worldwide. We present a data set containing eight morphological traits for 4,623 museum specimens of the seven largest collections in the country corresponding to 293 species of 14 families. The number of measured specimens per species ranged from 1 to 118 individuals with a median of 8 individuals per species. Overall, this database gathered morphological information for 37.6% of Colombian anuran diversity. Species measured were mainly distributed in the high Andean forest, the páramo, and wetland ecosystems, and was part of a national initiative led by the Instituto Alexander von Humboldt. The morphological traits were selected on the basis of their role in species' responses to environmental variability and their contributions to ecosystem processes. These traits were related to habitat use, (forearm length, tibia length, femur length, foot length, and foot webbing), predation and food chains (head width and mouth width), and nutrient recycling (snout–vent length). We expect this data set will be used in studies on functional diversity in amphibians and the development of conservation planning for these taxa. No copyright or proprietary restrictions are associated with the use of this data set other than citation of this Data Paper. [ABSTRACT FROM AUTHOR]

By critically reviewing different strands of literature on institutional change and development, this essay argues that, in order to fully understand subnational economic development, we need to move away from 'good governance' explanations in which geography‐specific analyses of power structures and elite interests are largely absent. Using findings for Colombia and insights from economic geography and heterodox political economy theories, this essay gives theoretical and conceptual guidelines and approximations for future studies on regional economic development. The contribution provides a place‐based discussion of how the historically evolved distribution of power balances, context‐specific elite interests, and the interaction between place‐bound actors and place‐less dynamics affect subnational institutional arrangements shaping policies and development outcomes. The conclusions drawn are not limited to Colombia and will prove beneficial to researchers studying regional economic development in subnational contexts elsewhere in the world.

In the protracted Colombian conflict, assistance to internally displaced persons has developed in the context of contradictory political processes. The Colombian government's launching of a transitional justice process in the midst of armed conflict has generated a complex situation displaying both conflict and post-conflict characteristics. The progressive Constitutional Court rulings on internal displacement, in particular the gender-sensitive Auto 092, constitute an attempt to bring together humanitarian interventions and transitional justice measures in a rights-based framework. However, the national government is reluctant to adopt them fully and local realities still hamper their integrated implementation. Displaced women, therefore, remain in an especially vulnerable position. This paper argues that gender-sensitive humanitarian interventions must take into account all of these complexities of scale and political process in order to make legal frameworks more effective at the local level. In these contexts, interventions should pay particular attention to strategies that contribute to transforming pre-existing gender regimes. [ABSTRACT FROM AUTHOR]

Few cities in Latin America provide much evidence of good governance. However, during the last fifteen years, Bogotá has been transformed and now qualifies in certain respects as an example of ‘best practice’. The paper considers how Bogotá changed and whether it can continue its improvement, an especially interesting question insofar as a left-wing administration has been in charge since 2004. Of course, the city is by no means perfect and national issues continue to create difficulties both for the poor and for the local administration. [ABSTRACT FROM AUTHOR]

The Spanish civil war saw two different Liberal presidencies in Colombia. Contrary to common belief, they did not follow a unified policy towards Spain but instead faced different parameters for action which shaped their response. These policies, in turn, illuminate both the internal dynamics of the two administrations and how they conceived of Colombia's position on the world stage. By providing the national, international and wider structural contexts, this article will therefore use the Spanish conflict to shine a spotlight on the Santos and López governments and the development of Colombian foreign policy during the late 1930s.

In this article I analyze the participation of economic patrons or gamonales in processes of city building. Like clientelistic leaders, local 'big men' can partake in the transformation of the living conditions of the urban poor. These individuals show an extraordinary capacity for transforming cities, their built environments and social and political infrastructures, especially in small and rapidly growing cities located in the peripheries of nation‐building projects. In my research I explore the case of one patron in Granada, a rapidly urbanizing city in Colombia that received many forced migrants between 1990 and 2010, to reveal a new way in which city building and patron–client relationships co‐evolve and are constituted within a space of intimate interactions between landed property and urban real estate.

The northwestern corner of South America presents a highly complex geodynamical setting including the convergence between South America, Nazca, and Caribbean plates; which also entails heterogeneity and complexity in the lithospheric structure. Here, we present depth‐migrated common‐conversion point (CCP) teleseismic receiver function profiles carried out using seismological data between 2011 and 2020 from the Colombian Geological Service, combined with some stations of observatories and international networks. These profiles provide better constraints on the lateral interpretation of the main lithospheric discontinuities in this region. We provide an updated crustal thickness map displaying some differences from previous studies, especially in the northernmost part of the cordilleran system. Our results also show some intracrustal features such as the regional detachment surface beneath the Eastern Cordillera and the presence of deep melt reservoirs under the Central Cordillera and the Paipa‐Iza complex in the Eastern Cordillera. We also discuss the lithospheric thickness and the potential existence of a highly hydrated and serpentinized mantle wedge under the forearc over the slab segment south of the Caldas tear. Furthermore, the CCP profiles further support the subduction system segmentation under northwestern South America, with at least five slab segments, two of them overlapping between ∼5.5 and ∼8°N, three belonging to the Nazca plate, and two having a Caribbean origin. The Bucaramanga nest appears to be linked to the interaction between the two northmost slab segments, while the Cauca cluster might be related to a slab dehydration process of a highly fractured zone. Plain Language Summary: The Colombian tectonic configuration is highly complex with the convergence of three major tectonic plates. Despite extensive recent studies in this region, some of the important tectonic features are still under discussion. In this study, we present cross‐section images of the lithospheric and upper mantle structure beneath Colombia, carrying out an analysis of teleseismic wave conversions corresponding to data collected between 2011 and 2020 by the Colombian Geological Service, volcanological and seismological observatories, and international stations. The results show that the crust is thinner than estimated in previous studies in the northernmost part of the Colombian cordillera system, and provide some material on intracrustal features and lithospheric thickness. Moreover, our images support other studies on the subduction system in this area, showing the presence of five slab segments on the Pacific side subducting beneath Colombia, including an overlapping segment between ∼5.5 and ∼8°N. The two densest seismic clusters, the Bucaramanga nest and the Cauca cluster, seem to be linked to the interaction of two plates at depth and the dehydration of a fractured slab zone, respectively. Key Points: Crustal thickness beneath northwestern South America with some significant changes from previous studiesWe observe five different slab segments under northwestern South AmericaRegional detachment surface under the Eastern Cordillera ranging between 10 and 30 km depth [ABSTRACT FROM AUTHOR]

This study is an attempt to understand flow patterns in the Middle Magdalena Valley River basin (MMV), a tropical lowland humid forest. For this purpose, we used δ2H and δ18O water stable isotopes measured in different surface and groundwater sources collected in the area both during the dry and the wet seasons. Two hundred and forty‐five water samples were collected in rainfall, springs, rivers, swamps, and wells (from 10 to 350 m depth). Thus, we were able to establish three tendencies that suggest the existence of surface‐groundwater interactions or preferential groundwater fluxes in the MMV: (i) samples with an isotopic enrichment from the wet to the dry season (groundwater samples following the rainfall isotopic variability), (ii) groundwater samples with an isotopic depletion from the wet to the dry season (opposite to the rainfall isotopic signal), and (iii) groundwater samples whose isotopic composition did not change significantly among seasons. However, none of these tendencies could be related to geology or the type of sampled site, which suggests that some not fully understood processes must be taking place in the hydrological system of the MMV. Both, surface, and groundwater samples are grouped close to the Colombian meteoric line, with exception of some swamp samples collected during the dry period, which displayed the expected evaporation trend line tendency. This may be an indicator of the connection/disconnection of swamps with the river during the hydrological year. Finally, this study aims to fulfil the gap in water‐stable isotope data in Colombia and provide insights about the hydrological setup of a lowland tropical basin. [ABSTRACT FROM AUTHOR]

The World Health Organization (WHO) has established a target to eliminate mother‐to‐child‐transmission (EMTCT) of hepatitis B virus (HBV), defined as a prevalence of hepatitis B surface antigen (HBsAg) of ≤0.1% among children, by 2030. Using nationally representative serosurveys to verify achievement of this target requires large sample sizes and significant resources. We assessed the feasibility of a potentially more efficient two‐phase method to verify EMTCT of HBV in Colombia. In the first phase, we conducted a risk assessment to identify municipalities at the highest risk of ongoing HBV transmission. We ranked the 1122 municipalities of Colombia based on the reports of HBV infection in pregnant women per 1000 population. Municipalities with ≥0.3 reports per 1000 persons (equating to the top quartile) were further assessed based on health facility birth rates, coverage with three doses of hepatitis B vaccine (HepB3) and seroprevalence data. Hepatitis B risk was considered to be further increased for municipalities with HepB3 coverage or health facility birth rate <90%. In the second phase, we conducted a multistage household serosurvey of children aged 5–10 years in 36 municipalities with the highest assessed HBV risk. HBsAg was not detected in any of 3203 children tested, yielding a 90% upper confidence bound of <0.1% prevalence. Coverage with HepB3 and hepatitis B birth dose was high at 97.5% and 95.6%, respectively. These results support the conclusion that Colombia has likely achieved EMTCT of HBV. [ABSTRACT FROM AUTHOR]

Objective: Intestinal parasitic infections (IPIs) are a public health challenge in developing countries such as Colombia, causing anaemia and delayed growth and development in children. We aimed to estimate the geographical and prevalence trend of IPIs in the last 30 years in school and preschool children in Colombia.Methods: We conducted a systematic review and meta-analysis. We identified potential manuscripts through PubMed, EMBASE, Web of Science, LILACS, Scielo and Google Scholar on the IPIs prevalence in school and preschool children in Colombia. Articles included in the qualitative analysis were published between 1990 and 2020 in English or Spanish and met the inclusion criteria. Subsequently, a random-effects meta-analysis, a meta-regression and a trend analysis were performed.Results: We identified 2292 articles; 109 were included in the qualitative review, and 79 articles were included in the meta-analysis. The estimated IPI prevalence was 55% (95% CI: 48-63). By age group, the prevalence in preschool children was 37% (95% CI: 26-49) and 66% (95% CI: 52-78) in schoolchildren. The prevalence by region was heterogeneous, with the Amazon being the highest (69%) and the Santanderes the lowest (28%). In the last 20 years, the prevalence of helminthiasis has decreased (from 64.66% in 1990-1995 to 22.09% in 2016-2020).Conclusion: The prevalence of IPIs is high (>30%) in three of the seven regions in Colombia. Biannual administration of mass deworming in schoolchildren is recommended in the Amazon region. Public policies aiming to control IPIs should be reinforced. Further prevalence studies should include Cesar, Guaviare, Vichada and Vaupés, where the epidemiology of IPIs is unknown.Sustainable Development Goals: Good health and wellbeing, clean water and sanitation, sustainable cities and communities.

ALPINE glaciers ,LITTLE Ice Age ,MELTWATER ,SOLAR radiation ,GLACIERS - Abstract
This study extends knowledge of the evolution of glacier shrinkage in the Cocuy‐Güican Mountains since the maximum glacier extent of the Little Ice Age (LIA). Mass balance data for the Ritacuba Glacier since 2009 were acquired and compared with available data for the Conejeras Glacier (Los Nevados National Park). This study also investigated the hydrological significance of Colombian glaciers, which is still largely unknown because the available information is very limited. Glaciers in the Cocuy‐Güican Mountains covered 13.2 km2 in 2019 compared with 127.8 km2 during the maximum LIA, representing a shrinkage of 89.7%. Analysis of glacier cover observations made in 1955, 1994, 2010, and 2019 revealed that the rate of ice loss was greatest from 1994 to 2010 (0.59 km2 yr−1), and was then almost halved from 2010 to 2019 (0.34 km2 yr−1). This slowing of glacier retreat is consistent with the moderate negative mass balance measured for 2009–2019, and an accumulated loss of 1766 mm w.e. (mm water equivalent). The progressive confinement of glaciers to higher elevations, ice accumulation in topographic locations providing shelter from solar radiation, and an absence of recent marked climatic anomalies could explain why the Cocuy‐Güican glaciers have temporally reached a near equilibrium state conditions. This contrasts with the Conejeras Glacier, where 47,000 mm w.e. has been lost in the same period. The available data on runoff and isotope tracers of streamflow and precipitation suggest that precipitation rather than glacier melt water exerts primary control over the hydrological variability at high elevation sites.
