Espacios de transición en los equipamientos culturales como elementos que potencian las dinámicas sociales

Este trabajo pretende hacer una reflexión sobre la importancia de los espacios de transición en los Equipamientos Colectivos, más exactamente los Centros Cívicos, la sinergia con el espacio público y los efectos que tienen en las dinámicas sociales en las ciudades y los barrios. Los equipamientos colectivos son un componente importante en la planeación de las ciudades. Su principal función ha sido la de ofrecer servicios para los ciudadanos por medio de espacios que promueven actividades, reunión, participación y encuentro. Para lograrlo, deben en su mayoría estar acompañados de componentes que aseguren la accesibilidad y cobertura equilibrada en el territorio. Se entienden por esos componentes, al espacio público de calidad, la accesibilidad por medio de transporte público y privado, la calidad en la configuración de los espacios, y la igualdad de condiciones, que permiten el acceso a todos los ciudadanos sin importar edad, raza, género y condición física, promoviendo inclusión y generando una cohesión social. Son estos componentes los que serán profundizados en este trabajo, y se apoyarán en un análisis realizado en una escala mas reducida, de 1:1, sobre el edificio, los Centros Cívicos, y la simbiosis con el Espacio Público, la Morfología y el Entorno. Identificando el potencial que tienen estos componentes cuándo son de verdad pensados para las personas y se aprovecha la función social que cumplen en el territorio. Para realizar este análisis se decidió escoger una Ciudad como base principal de estudio, donde el desarrollo de la ciudad esté o haya estado fundamentada la participación social y su principal objetivo sea mejorar la calidad de vida de sus habitantes. La Ciudad escogida es Barcelona, aunque conocida por sus transformaciones e innovaciones urbanísticas, aún no ha sido completamente explorada desde la completa red de equipamientos que históricamente ha estado ligada con la democracia de su territorio. Esta es una de sus fortalezas y hace de esta ciudad un buen ejemplo para estudiar y analizar. Este gran laboratorio, cómo es la Barcelona, será usado en este trabajo para estudiar y encontrar esos puntos de convergencia, donde la arquitectura promueve las interacciones, cumple la función de integrador y logra generar o influir positivamente en el proceso de apropiación espacial por parte de los ciudadanos. Con el fin de identificar fortalezas, debilidades o potencialidades en los equipamientos colectivos y su verdadero aporte a la cohesión social del territorio. Entendiendo que al final lo que hace la diferencia es la manera de implantarlo, pues el concepto o tipología ya está un poco más desarrollado

The hassles & uplifts scale

A escala Hassles & Uplifts avalia a intensidade da resposta a pequenos eventos cotidianos, sendo considerada um preditor de sintomas psicológicos. O objetivo deste estudo foi avaliar uma tradução da escala Hassles & Uplifts, aqui intitulada Aborrecimentos e Alegrias; para tal, realizou-se a réplica de um estudo norte-americano que mediu o desempenho, nessa escala, de indivíduos cujo padrão de comportamento fosse do tipo A ou B segundo a escala de Jenkins (Escala Aborrecimentos e Alegrias). As escalas Aborrecimentos e Alegrias e A/B foram aplicadas em 145 universitários brasileiros. Os resultados mostraram que: 1) as pontuações médias de Aborrecimentos e Alegrias foram similares às do estudo norte-americano, exceto pelos Aborrecimentos dos participantes tipo B; 2) a intensidade das Alegrias dos participantes tipo A foi significativamente superior à dos tipo B, como na literatura; 3) a intensidade de Alegrias e Aborrecimentos não diferiu entre os dois tipos, provavelmente devido à especificidade da época do teste. Concluiu-se que o padrão e a consistência dos resultados indicam que a tradução pode ser utilizada como instrumento confiável de pesquisa.The Hassles & Uplifts Scale assesses the reaction to minor every-day events in order to detect subtle mood swings and predict psychological symptoms. The aim of this study was to evaluate the Portuguese translation of Hassles & Uplifts (Aborrecimentos e Alegrias) through the replication of a North American study which used this scale to measure the performance of individuals with type A and type B behavior patterns. The Aborrecimentos e Alegrias and Jenkins A/B scales were answered by 145 Brazilian college students. Results showed that: 1) The average Aborrecimentos e Alegrias scores were similar to the North American study, except for the type-B Hassles scores; 2) Uplifts received higher scores than Hassles from both types, substantiating literature on the subject; 3) the intensity of Hassles and Uplifts did not differ between types A and B, probably due to the timing of the testing period. It was concluded that the pattern and consistency of the results indicate that the translation can be used as a reliable research tool

Embodied GHG emissions of buildings – The hidden challenge for effective climate change mitigation

Buildings are major sources of greenhouse gas (GHG) emissions and contributors to the climate crisis. To meet climate-change mitigation needs, one must go beyond operational energy consumption and related GHG emissions of buildings and address their full life cycle. This study investigates the global trends of GHG emissions arising across the life cycle of buildings by systematically compiling and analysing more than 650 life cycle assessment (LCA) case studies. The results, presented for different energy performance classes based on a final sample of 238 cases, show a clear reduction trend in life cycle GHG emissions due to improved operational energy performance. However, the analysis reveals an increase in relative and absolute contributions of so‐called ‘embodied’ GHG emissions, i.e., emissions arising from manufacturing and processing of building materials. While the average share of embodied GHG emissions from buildings following current energy performance regulations is approximately 20–25% of life cycle GHG emissions, this figure escalates to 45–50% for highly energy-efficient buildings and surpasses 90% in extreme cases. Furthermore, this study analyses GHG emissions at time of occurrence, highlighting the ‘carbon spike’ from building production. Relating the results to existing benchmarks for buildings’ GHG emissions in the Swiss SIA energy efficiency path shows that most cases exceed the target of 11.0 kgCO$^{2}$eq/m$^{2}$a. Considering global GHG reduction targets, these results emphasize the urgent need to reduce GHG emissions of buildings by optimizing both operational and embodied impacts. The analysis further confirmed a need for improving transparency and comparability of LCA studies

Embodied GHG emissions of buildings - Critical reflection of benchmark comparison and in-depth analysis of drivers

In the face of the unfolding climate crisis, the role and importance of reducing Greenhouse gas (GHG) emissions from the building sector is increasing. This study investigates the global trends of GHG emissions occurring across the life cycle of buildings by systematically compiling life cycle assessment (LCA) studies and analysing more than 650 building cases. Based on the data extracted from these LCA studies, the influence of features related to LCA methodology and building design is analysed. Results show that embodied GHG emissions, which mainly arise from manufacturing and processing of building materials, are dominating life cycle emissions of new, advanced buildings. Analysis of GHG emissions at the time of occurrence, shows the upfront \u27carbon spike\u27 and emphasises the need to address and reduce the GHG \u27investment\u27 for new buildings. Comparing the results with existing life cycle-related benchmarks, we find only a small number of cases meeting the benchmark. Critically reflecting on the benchmark comparison, an in-depth analysis reveals different reasons for cases achieving the benchmark. While one would expect that different building design strategies and material choices lead to high or low embodied GHG emissions, the results mainly correlate with decisions related to LCA methodology, i.e. the scope of the assessments. The results emphasize the strong need for transparency in the reporting of LCA studies as well as need for consistency when applying environmental benchmarks. Furthermore, the paper opens up the discussion on the potential of utilizing big data and machine learning for analysis and prediction of environmental performance of buildings

Postcranial remains of basal typotherian notoungulates from the eocene of Northwestern Argentina

Notoungulates represent the most taxonomically diverse and temporally and geographically widespread group among South American native ungulates. Here, we analyze anatomical and systematic aspects of proximal tarsal bones recovered from the Lower and Upper Lumbrera formations (middle and late middle Eocene) in northwestern Argentina. We provide detailed descriptions, comparisons, and infer foot stances and range of movements for the taxa implicated. Material studied includes astragali belonging to the oldfieldthomasiid Colbertia lumbrerense (Lower Lumbrera Formation), a set of proximal tarsals referred as Typotheria indet. (Lower Lumbrera Formation), and tarsals (also including navicular and cuboid) of the informal taxon “Campanorco inauguralis” (Upper Lumbrera Formation). The comparison of the tarsals of Colbertia lumbrerense (middle Eocene of Argentina) with Colbertia magellanica (early Eocene of Brazil) reveals several differences including variations on the development and arrangement of articular facets, and the size of the dorsal astragalar foramen in the Argentinean species. The specimen of Typotheria indet. shows morphological affinities with basal interatheriid taxa. However, its larger size contrasting with the overall small body sizes of Eocene interatheriids precludes an indisputable taxonomic assignment. Concerning “Campanorco inauguralis”, our observations indicate that there is no morphological evidence for a close phylogenetic relationship with Mesotheriidae. It presents a “reversed alternating tarsus” condition, which is also observed in Leontiniidae, “Notohippidae”, Toxodontidae, and some typotherians. However, the spectrum of singularities exhibited by this form precludes the assessment of its relationships in the context of the Paleogene radiation of Typotheria and it is necessary to extend the comparison to Eocene notoungulates. Finally, in a morphofunctional context a plantigrade foot posture is inferred for the specimens here reported. These observations have the potential to provide functional proxies for paleoecological reconstructions to be applied to the study of the early radiation of these notoungulate faunas.Fil: Armella, Matías Alberto.

Evaluation of anthropometric facial landmarks in woman with Blepharophimosis, Ptosis, and Epicanthus Inversus Syndrome (BPES)

Introduction: Blepharophimosis, ptosis, and epicanthus inversus syndrome (BPES) is a syndrome easily recognized by facial appearance. In this sense, the facial anthropometry is a simple and non-invasive way to evaluate the morphology of the facial surface of individuals, thus, defining the craniofacial dimensions. Objective: To evaluate the facial anthropometric measurements of a Caucasian female, aged 20 years, diagnosed with BPES and to compare these measures with the values described in the literature for non-syndromic woman.Material and methods: This research is an observational study of a Caucasian female, aged 20 years, who was diagnosed with BPES. Frontal photographs were taken, and the images analyzed by nine researchers calibrated in Image J® software. The facial measurements evaluated were head, face, orbits, nose, and labio-oral region and were compared with non-syndromic woman. Results: All vertical and horizontal face measurements were higher than that of otherfemales from Caucasian groups. BPES woman also presented bilateral ptosis and the main differences appear in the region of the orbits. Conclusion: The anthropometric facial analysis of BPES woman showed a significant change in the facial landmarks.Introduction: Blepharophimosis, ptosis, and epicanthus inversus syndrome (BPES) is a syndrome easily recognized by facial appearance.

Electrospun Ta-MOF/PEBA Nanohybrids and Their CH4 Adsorption Application

For the first time, biocompatible and biodegradable Ta-metal organic framework (MOF)/polyether block amide (PEBA) fibrous polymeric nanostructures were synthesized by ultrasonic and electrospinning routes in this study. The XRD peaks of products were wider, which is due to the significant effect of the ultrasonic and electrospinning methods on the final product. The adsorption/desorption behavior of the nanostructures is similar to that of the third type of isotherm series, which showed mesoporous behavior for the products. The sample has uniform morphology without any evidence of agglomeration. Since the adsorption and trapping of gaseous pollutants are very important, the application of the final Ta-MOF/PEBA fibrous polymeric nanostructures was investigated for CH4 adsorption. In order to achieve the optimal conditions of experiments and also systematic studies of the parameters, fractional factorial design was used. The results showed that by selecting temperature 40°C, time duration 35 min, and pressure 3 bar, the CH4 gas adsorption rate was near 4 mmol/g. Ultrasonic and electrospinning routes as well as immobilization of Ta-MOF in the PEBA fibrous network affect the performance of the final products for CH4 gas adsorption

Functional assessment using 3D movement analysis can better predict health-related quality of life outcomes in patients with adult spinal deformity: a machine learning approach

IntroductionAdult spinal deformity (ASD) is classically evaluated by health-related quality of life (HRQoL) questionnaires and static radiographic spino-pelvic and global alignment parameters. Recently, 3D movement analysis (3DMA) was used for functional assessment of ASD to objectively quantify patient's independence during daily life activities. The aim of this study was to determine the role of both static and functional assessments in the prediction of HRQoL outcomes using machine learning methods.MethodsASD patients and controls underwent full-body biplanar low-dose x-rays with 3D reconstruction of skeletal segment as well as 3DMA of gait and filled HRQoL questionnaires: SF-36 physical and mental components (PCS&MCS), Oswestry Disability Index (ODI), Beck's Depression Inventory (BDI), and visual analog scale (VAS) for pain. A random forest machine learning (ML) model was used to predict HRQoL outcomes based on three simulations: (1) radiographic, (2) kinematic, (3) both radiographic and kinematic parameters. Accuracy of prediction and RMSE of the model were evaluated using 10-fold cross validation in each simulation and compared between simulations. The model was also used to investigate the possibility of predicting HRQoL outcomes in ASD after treatment.ResultsIn total, 173 primary ASD and 57 controls were enrolled; 30 ASD were followed-up after surgical or medical treatment. The first ML simulation had a median accuracy of 83.4%. The second simulation had a median accuracy of 84.7%. The third simulation had a median accuracy of 87%. Simulations 2 and 3 had comparable accuracies of prediction for all HRQoL outcomes and higher predictions compared to Simulation 1 (i.e., accuracy for PCS = 85 ± 5 vs. 88.4 ± 4 and 89.7% ± 4%, for MCS = 83.7 ± 8.3 vs. 86.3 ± 5.6 and 87.7% ± 6.8% for simulations 1, 2 and 3 resp., p < 0.05). Similar results were reported when the 3 simulations were tested on ASD after treatment.DiscussionThis study showed that kinematic parameters can better predict HRQoL outcomes than stand-alone classical radiographic parameters, not only for physical but also for mental scores. Moreover, 3DMA was shown to be a good predictive of HRQoL outcomes for ASD follow-up after medical or surgical treatment. Thus, the assessment of ASD patients should no longer rely on radiographs alone but on movement analysis as well
