This study aimed to assess the effect of the Lower Extremity Constraint-Induced Movement Therapy (LE-CIMT) intervention on the intra-limb hip-knee coordination and its variability in walking in chronic post-stroke individuals considering the lenses of the dynamic systems approach to motor behavior. Twelve chronic post-stroke individuals received the LE-CIMT intervention for 10 days following all protocol’s recommendations and designed according to individuals’ needs. Before, three days, and 30 days after the intervention, angular kinematics in the sagittal plane of the trunk, hip and knee of both extremities were analyzed. We analyzed joint angles for swing and stance phases of walking, and the intra-limb coordination of hip-knee joints through the vector coding technique. For separate joint angular kinematics, we found differences between affected extremities but no effects of the intervention. However, we observed changes in intra-limb coordination pattern as a function of increased variability after intervention and increased stability at follow-up. These changes follow the predicted pattern from the dynamic systems approach to motor behavior. The immediate decreased stability of the initial pattern could be due to the active exploration of space solution offered by the LE-CIMT and, posteriorly, the stability increased after finding new movement solutions in the real-life environment.

Este libro es un esfuerzo conjunto de investigadores de Brasil, México y Colombia, y del semillero de investigación Estudios sociales del desarrollo y los territorios del Programa de Sociología de la Universidad Nacional Abierta y a Distancia - UNAD, que busca identificar los factores asociados que impulsan o desincentivan la participación política en la población de sus países, con una visión multidisciplinar que estudia este fenómeno social a través de disciplinas como la economía, la ciencia política, la psicología y demás ciencias que aportan al conocimiento. Las democracias latinoamericanas tienen como reto enorme y permanente generar mecanismos que permitan la participación política a sus ciudadanos; entender los factores asociados a dicha participación es el reto que se propone el libro, el cual aborda la participación política en dos enfoques: uno ligado a la participación política electoral, que es uno de los ejercicios de derechos más comunes en Latinoamérica, complementándolo con una segunda mirada, la cual está ligada a la participación sociopolítica de los ciudadanos en organizaciones sociales. Ambos enfoques de participación política permiten al lector entender cuáles son las probabilidades de cada uno de los factores o dimensiones asociados a la participación política tanto a nivel de características individuales del ciudadano, como de los factores asociados a contextos socioeconómicos, que terminan afectando en mayor proporción la decisión de participar bien sea en un proceso político electoral o en una organización político social.

CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior Este trabajo analiza organizaciones comunitarias de abastecimiento de agua, sus repercusiones (simbólicas, políticas y técnicas) y su posibilidad de articulación y complementariedad con la gestión estatal del servicio del agua. Para ello, se seleccionaron tres organizaciones comunitarias del servicio del agua, también conocidas como “acueductos comunitarios”, en la ciudad de Villavicencio, en Colombia. Localizada donde la cordillera Oriental de los Andes colombianos se encuentra con la región conocida como Llanos Orientales, en el centro del país, Villavicencio posee 531.275 habitantes y ha experimentado fuertes transformaciones urbanas y socioeconómicas en los últimos veinte años. El principal prestador del servicio de abastecimiento de agua en la ciudad es la Empresa de Acueducto y Alcantarillado de Villavicencio (EAAV), una empresa municipal que ha sido criticada por presentar diversas deficiencias técnicas y administrativas, tales como cortes prolongados en el servicio. En este contexto, una multiplicidad de prestadores, privados y comunitarios, han surgido en el tejido urbano, poniendo en entredicho la idea de que el modelo de distribución universal e industrial de agua constituye un monopolio natural y la vía única -e idónea – para la prestación del agua en las ciudades. Por medio de una metodología de investigación-acción, este trabajo, llevado a cabo entre 2017 y 2022, empleó diversos procedimientos metodológicos cualitativos como la observación participante, entrevistas semiestructuradas, censos comunitarios y talleres participativos. Orientada por la ecología política, el enfoque de los “bienes comunes”, propio de la Teoría de la Acción Colectiva (Ostrom, 2011), y las reflexiones de Dardot y Laval (2010, 2015) sobre “lo común” como un proceso político, esta investigación levanta tres reflexiones principales. Primero, se interroga sobre la pertinencia técnica y los efectos sociales del gran sistema de redes de infraestructura de agua. Segundo, aunque los acueductos comunitarios también presentan conflictos y dificultades, se reconoce la gestión comunitaria del servicio del agua como estrategia de abastecimiento flexible, participativa y contestataria, donde las organizaciones comunitarias han dado origen, además, a movimientos sociales más amplios que cuestionan los principios -normativos e ideológicos – que sustentan la gestión del servicio del agua en Colombia. Tercera, y como propuesta general de este trabajo, se señala la posibilidad de articular la acción pública con estrategias comunitarias de abastecimiento de agua de escala local, forjando nuevos paradigmas de gestión del servicio de agua, más democráticos, más sostenibles y más pertinentes para la realidad de las ciudades. This research analyzes community water supply organizations, their effects (symbolic, political and technical), as well as possibilities of articulation and complementarity with public management. For this purpose, three community water service organizations were selected in the city of Villavicencio, Colombia. Located where the eastern mountain range of the Colombian Andes meets the region known as Llanos Orientales, in the center of the country, Villavicencio has 531,275 inhabitants and has undergone strong urban and socioeconomic transformations in the last twenty years. The main provider of water supply services in the city is the Empresa de Acueducto y Alcantarillado de Villavicencio (EAAV), a public company that has been criticized for various technical and administrative deficiencies, such as extended service cuts. In this context, a multiplicity of private and community providers have emerged in the urban area, challenging the idea that the universal and industrial water distribution model is a natural monopoly and the only - and ideal - way for water supply in the cities. Through an action research methodology, this work, carried out between 2017 and 2022, employed various qualitative methodological procedures such as participant observation, semi-structured interviews, community censuses and participatory workshops. Guided by the political ecology approach, the "commons" perspective of the Theory of Collective Action (Ostrom, 2011), and Dardot and Laval's (2010, 2015) arguments about "the common" as a political process, this research raises three main considerations. First, it questions the technical relevance and social effects of the "big system" of water infrastructure networks. Second, although community water organizations also present conflicts and difficulties, they can be recognized as a flexible and more democratic supply model, where community organizations have also given rise to broader social movements that question the principles - normative and ideological - that underpin the water services management in Colombia. Third, and as a general proposal of this research, it suggests the possibility of articulating public action with community water supply strategies at a local scale, forging new paradigms of water service management that are more democratic, more sustainable and more relevant to the reality of the cities.

The occurrence of Alzheimer's disease (AD) can exert a negative impact in social participation in affected older adults. The purpose of this study was to investigate whether social participation in older adults with AD is associated with disease stage and cognitive function as well as the quality of life and depressive symptoms in their caregivers. A correlational, cross-sectional study was conducted in 40 older adults with AD (28 women and 12 men) and 40 caregivers (30 women and 10 men). Social participation was assessed using the 'social participation' domain of the Activities of Daily Living Questionnaire. Disease stage was determined using the Clinical Dementia Rating scale and cognitive function was assessed using Addenbrooke's Cognitive Examination. Quality of life and depressive symptoms in the caregivers were evaluated using the Quality of Life Assessment Scale on Alzheimer's Disease and Beck Depression Inventory respectively. The older adults with AD had a mean percentage of 59.4% on the social participation domain and a mean score of 49.0 for cognitive function. The caregivers had mean scores of 39.1 for quality of life and 9.9 for depressive symptoms. The stepwise backward multiple linear regression model indicated that the predictors analysed together explained 48% of the variability in social participation among older adults with AD. Therefore, lower social participation among older adults with AD is associated with more advanced stages of the disease and cognitive decline in these individuals as well as a lower perception of quality of life and greater levels of depressive symptoms in their caregivers.

Mixing acerola pulp with whey, a by-product of the dairy industry, led to this study, whose aim was the development of a powdered beverage mix of acerola pulp, whey and maltodextrin (DE20). To determine the proportions of the mixture, a simplex-centroid mixture design was used. Different proportions of the mixture were dehydrated in a spray dryer at 175 °C. The results were evaluated in relation to hygroscopicity, moisture and ascorbic acid. Higher proportions of whey and pulp increased hygroscopicity and moisture, while maltodextrin reduced these parameters. An increase in pulp content raised the levels of ascorbic acid. The proportions (m m-1) of 50% acerola pulp, 25% whey and 25% maltodextrin resulted in significantly lower hygroscopicity (8.25 g 100 g-1) and moisture (1.66%), and appreciable levels of ascorbic acid (1492.49 g 100 g-1). The results indicated that the powder obtained shows good stability after 75 days of storage, with 9.20%, 1.79% and 1146.13 g 100 g-1 of hygroscopicity, moisture and ascorbic acid respectively. RESUMO A mistura de polpa de acerola com soro lácteo, subproduto da indústria de laticínios, conduziu a base deste trabalho, cujo objetivo foi desenvolver uma bebida composta em pó de polpa de acerola, soro lácteo e maltodextrina (dextrose equivalente 20). Para determinação das proporções da mistura foi utilizado um delineamento de misturas de tipo Simplex Centroide. Diferentes proporções da mistura foram desidratadas em secador tipo spray dryer à 175 ºC. Os resultados foram avaliados em relação a higroscopicidade, umidade e ácido ascórbico. Maiores proporções de soro e polpa, elevaram a higroscopicidade e umidade, enquanto que a maltodextrina reduziu estes parâmetros. O aumento do teor de polpa elevou os valores de ácido ascórbico. Proporções (m m-1) de 50% polpa de acerola, 25% soro lácteo e 25% maltodextrina, resultaram em higroscopicidade (8,25 g 100g-1) e umidade (1,66 %) significativamente baixos e valores apreciáveis de ácido ascórbico (1492, 49 g 100g-1). Os resultados indicaram que o pó obtido possui boa estabilidade após 75 dias de armazenamento com 9,20 %, 1,79 % e 1146,13 g 100 g-1 de higrocopicidade, umidade e ácido ascórbico, respectivamente.

In the Paris agreement about climate change, it was established that greenhouse gas emissions must be reduced by 0% in order to avoid irreversible damage, so the world economy based on fossil fuels must undergo a transformation towards an economy clean, safe and sustainable. As a result, it has been established that the only alternative that guarantees 0% emissions of polluting gases is the economy of hydrogen. Countries such as the Netherlands, the United States, and the European Union have projected policy towards 2050 that expects to meet the objectives set out in the Paris agreement. In this document shows the different alternative fuels that are currently being proposed to mitigate polluting emissions, as well as the overview of these fuels in Colombia, and how, from the different renewable energy sources that this country has, could venture economically and politically towards economy based on the use of hydroxy and hydrogen as a raw material and energy source, showing its possible applications. The foregoing will allow to identify the potential of application of these fuels in the energy matrix of Colombia and define policies to accelerate their implementation.Keywords: Environmental Pollution, Energy Policy, Alternative Fuels, Hydrogen, Renewable Energy.JEL Classifications: L78, L90, O31, Q20DOI: https://doi.org/10.32479/ijeep.8395

This study determined the ratio between glenohumeral and three-dimensional scapular motion during arm elevation and lowering in 91 individuals without shoulder pain. Scapular kinematics were assessed using an electromagnetic tracking device. Individuals performed 3 repetitions of elevation and lowering of the arm in the sagittal plane. Two-way ANOVAs (interval: 30-60°, 60-90°, 90-120° x phase: elevation and lowering) and paired t-tests were used for data analysis. For scapular internal/external rotation, lesser scapular internal rotation contribution was found during the 60-90° interval as compared to the 90-60° interval. Lesser scapular external rotation was identified in the 60-30° interval of arm lowering. The ratio was greater during arm elevation (1.89) compared to lowering (1.74) across the entire motion arc. For scapular upward rotation, greater upward rotation contribution was observed during arm elevation at the 30-60° interval, and less scapular downward rotation contribution in the final range of arm lowering. For scapular tilt, lesser scapular posterior tilt contribution during arm elevation was observed compared to arm lowering. The ratios between glenohumeral elevation/lowering and each individual scapulothoracic motion showed either differences between intervals and/or between elevation and lowering during specific intervals in healthy individuals.
