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 work explores the results of a creative and art‐based intervention to foster reconciliation in Colombia. The paper presents a novel methodology defined as 'Art for Reconstruction', piloted with victims of violence, veterans from armed forces and former members of illegal groups between 2018 and 2019 in Medellín, Colombia. The initiative encouraged trauma healing, reduced intergroup hostility, fostered cooperation and willingness to reconcile among previous enemies. Results show that creative and art‐based approaches, like Kintsugi, are promising to transform citizens' interactions at the micro level. This project presents how art and social engagement facilitate transitions from war to peace and reconciliation. [ABSTRACT FROM AUTHOR]

Statistical analysis of point processes often assumes that the underlying process is isotropic in the sense that its distribution is invariant under rotation. For point processes on ℝ2, some tests based on the K‐function and nearest neighbour orientation function have been proposed to check such an assumption. However, anisotropy and directional analysis need proper caution when dealing with point processes on linear networks, as the implicit geometry of the network forces particular directions that the points of the pattern have to necessarily meet. In this paper, we adapt such tests to the case of linear networks and discuss how to use them to detect particular directional preferences, even at some angles that are different from the main angles imposed by the network. Through a simulation study, we check the performance of our proposals under different settings, over a linear network and a dendrite tree, showing that they are able to precisely detect the directional preferences of the points in the pattern, regardless the type of spatial interaction and the geometry of the network. We use our tests to highlight the directional preferences in the spatial distribution of traffic accidents in Barcelona (Spain), during 2019, and in Medellin (Colombia), during 2016.

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]

This article reports on a joint meeting of International Union of Forestry Research Organizations working parties held to discuss pests and diseases of pine in the tropics. The meeting was held at the Forest Protection Laboratories at Priedras Blancas, near Medellin, Colombia, over the period 3rd to 8th September 1978. The main objectives of the meeting were to integrate the organization and future activities of the two working parties and provide an opportunity for technical exchange between them. The papers presented gave a basis for a valuable exchange of information and ideas.

The Monte Azul archaeological site is located in the inter‐Andean Aburrá Valley of the upper Medellín River in Colombia and it is dated from the Middle Ceramic period to the Republican period. In this study area, it is common to find evidence of disturbed soils that is related to ancient use and erosion. In Monte Azul, the pedogenesis is associated with the presence of fast‐weathering eolian volcanic ash deposits, extreme acidity, low base saturation, strong leaching, high precipitation, and high temperature; hence, some of these tropical conditions are responsible for the low conservation of the archaeological record. Consequently, we used a geoarchaeological approach with paleoenvironmental, sedimentary, geochemical, and soil micromorphological proxies as integral units of analysis to understand site formation processes. Micromorphological and paleobotanical records indicate soil use dynamics and changes in paleoenvironmental conditions from humid conditions to small and persistent clearings around a domestic unit. This approach sheds light on the development of possible pre‐Hispanic activity areas and cultivation techniques related to the ancient use of the Ferrería pottery style in the Central Mountain Range of Colombia.

From the U.S. to Colombia to China, millions of public surveillance cameras are at the core of crime prevention strategies. Yet, we know little about the effects of surveillance cameras on criminal behavior, especially in developing economies. We study an installation program in Medellín and find that the quasi‐random allocation of cameras led to a decrease in crimes and arrests. With no increase in the monitoring capacity and no chance to use camera footage in prosecution, these results suggest offenders were deterred rather than incapacitated. We test for spillovers and find no evidence of crime displacement or diffusion of benefits to surrounding locations. [ABSTRACT FROM AUTHOR]

Objective: To assess the presence, pattern and magnitude of socioeconomic inequalities on dengue, chikungunya and Zika in Latin America, accounting for their spatiotemporal distribution. Methods: Using longitudinal surveillance data (reported arboviruses) from Fortaleza, Brazil and Medellin, Colombia (2007–2017), we fit Bayesian hierarchical models with structured random effects to estimate: (i) spatiotemporally adjusted incidence rates; (ii) Relative Concentration Index and Absolute Concentration Index of inequality; (iii) temporal trends in RCIs; and (iv) socioeconomic‐specific estimates of disease distribution. The spatial analysis was conducted at the neighbourhood level (urban settings). The socioeconomic measures were the median monthly household income (MMHI) for Brazil and the Socio‐Economic Strata index (SES) in Colombia. Results: There were 281 426 notified arboviral cases in Fortaleza and 40 887 in Medellin. We observed greater concentration of dengue among residents of low socioeconomic neighbourhoods in both cities: Relative Concentration Index = −0.12 (95% CI = −0.13, −0.10) in Fortaleza and Relative Concentration Index = −0.04 (95% CI = −0.05, −0.03) in Medellin. The magnitude of inequalities varied over time across sites and was larger during outbreaks. We identified a non‐monotonic association between disease rates and socioeconomic measures, especially for chikungunya, that changed over time. The Relative Concentration Index and Absolute Concentration Index showed few if any inequalities for Zika. The socioeconomic‐specific model showed increased disease rates at MMHI below US$400 in Brazil and at SES‐index below level four, in Colombia. Conclusions: We provide robust quantitative estimates of socioeconomic inequalities in arboviruses for two Latin American cities. Our findings could inform policymaking by identifying spatial hotspots for arboviruses and targeting strategies to decrease disparities at the local level. [ABSTRACT FROM AUTHOR]

The study analysed pre‐Hispanic gold objects found within a surprising archaeological finding of a structure that likely served as a funeral pyre in Medellín, Colombia. 14C analyses of the site's organic materials dated the structure to the fifth century ce. The metal objects were subjected to X‐ray diffraction (XRD), energy‐dispersive X‐ray fluorescence (EDXRF), scanning electron microscopy‐energy dispersive X‐ray (SEM‐EDX), density measurement by the Archimedes method, and metallographic analysis. The measurements by EDXRF and SEM‐EDX showed that the pieces were composed mostly gold and silver. The XRD results indicated that the microstructure of the objects corresponded to a single phase of gold and silver. The images obtained by the metallographic microscope showed equiaxial grains with some twins, a structure consistent with annealed metals. The different colours observed correspond to different grain orientations. Pre‐Hispanic objects from a second archaeological site in the municipality of Amalfi (Department of Antioquia) were also analysed for comparative purposes. The results showed that the gold objects were not subjected to any alloying process, but were instead manipulated in their original form (native gold). The shape of the objects and their microstructural results suggested that the pieces were manufactured by casting, mechanical deformation and then annealing. [ABSTRACT FROM AUTHOR]

Summary: We propose a computationally efficient and statistically principled method for kernel smoothing of point pattern data on a linear network. The point locations, and the network itself, are convolved with a two‐dimensional kernel and then combined into an intensity function on the network. This can be computed rapidly using the fast Fourier transform, even on large networks and for large bandwidths, and is robust against errors in network geometry. The estimator is consistent, and its statistical efficiency is only slightly suboptimal. We discuss bias, variance, asymptotics, bandwidth selection, variance estimation, relative risk estimation and adaptive smoothing. The methods are used to analyse spatially varying frequency of traffic accidents in Western Australia and the relative risk of different types of traffic accidents in Medellín, Colombia.

HLA-DRB1, DRB3, DRB4, DRB5 and DQB1 polymorphisms were studied using molecular methods in a population of 100 unrelated healthy individuals from an area in north-west Colombia (Medellin) inhabited by the “Paisa”, a community with features of a genetically isolated group. The most frequently observed specificities at the DRB1 locus were *07 (16.4%) and *15 (12%), and at the DQB1 locus *02 (18.8%) and *03 (33.6%), of which *0302 was the most prevalent allele (14.3%). The most polymorphic specificities were DRB1*04, 13 and 11, and DQB1*06. Both the HLA-DRB1 and DQB1 loci were in linkage disequilibrium. Haplotypes were estimated using maximum likelihood methods. The most frequent two locus haplotype was DRB1*07-DQB1*02 (6.6%) and these specificities were in linkage disequilibrium. Several unusual possible haplotypes were observed. Both the HLA-DRB1 and DQB1 locus were in Hardy–Weinberg equilibrium. [ABSTRACT FROM AUTHOR]
