Abstract: Bogotá Social Backbone proposes the development of a backbone of social infrastructure for the most needed people in Bogota, those who usually do not have access to the professional services of an architect. I selected three ""free"", abandoned, and problematic spaces along the Caracas Avenue in Bogotá, and three clients who inhabit them; a drug addict who was displaced from El Bronx, a prostitute from Santafé neighborhood and a recycler from Caracas 59. Social architecture is proposed with the objective of being a platform for these people to reintegrate into society with dignity, providing minimal housing, as well as places for training and for the development of a life project. Resumen: Bogotá Social Backbone propone el desarrollo de una columna vertebral de infraestructura social para las personas más necesitadas de Bogotá, aquellas que normalmente no tienen acceso a los servicios profesionales de un arquitecto. Seleccioné tres espacios ""libres"", abandonados y problemáticos a lo largo de la Avenida Caracas en Bogotá y tres clientes que los habitan; un drogadicto desplazado de El Bronx, una prostituta del barrio Santafé y un reciclador de la Caracas con 59. La arquitectura social se propone con el objetivo de ser una plataforma para que estas personas se reintegren dignamente a la sociedad, proporcionándoles una vivienda mínima, así como lugares para la formación y para el desarrollo de un proyecto de vida.

Abstract: Colombia is a country whose economy is largely driven by SMEs companies, but with the advance of technology, their production and growth is stagnating. Only companies that have under- stood the importance of innovation and have applied technologies framed in the DIGITAL TRANSFORMATION are making progress. One of the most critical reasons why these companies have not yet begun to go through this change of ideology is due to the lack of knowledge and support. The information is abundant but it is not compiled in a single digital site, where any- one can find it. Companies will continue to invest in technology to support the shift towards remote work and automation, but that is no longer enough. One of the most relevant findings when talking to various stakeholders, has been to understand that in the collective imagination of entrepreneurs, there are misconceptions about what DT means. It is common that this concept is framed in a series of myths that confuse and are transferred from voice to voice, creating a panorama of misinformation. That is why, I took on the challenge of creating a digital strategy that brings together in one place the dimensions that are part of the DT. The objective is to demystify the preconceived ideas of entrepreneurs so they can understand that their perception of digital reality has been created under ideas that do not correspond to the truth. Therefore, to achieve this change of mentality, a common and direct language will be used in order to make people feel identified with their false ideas about the concept and as a result, they will experience a desire to explore further. Resumen: Colombia es un país cuya economía está en gran medida impulsada por empresas pymes, pero con el avance de la tecnología, su producción y crecimiento se están estancando. Solo las empresas que han comprendido la importancia de la innovación y han aplicado tecnologías enmarcadas en la TRANSFORMACIÓN DIGITAL están progresando. Una de las razones más críticas por las cuales estas empresas aún no han comenzado a pasar por este cambio de ideología se debe a la falta de conocimiento y apoyo. La información es abundante, pero no está recopilada en un solo espacio digital, donde cualquiera pueda encontrarla. Las empresas continúan invirtiendo en tecnología para respaldar el cambio hacia el trabajo remoto y la automatización, pero eso ya no es suficiente. Uno de los hallazgos más relevantes al hablar con diversos interesados ha sido comprender que en la imaginación colectiva de los empresarios, hay conceptos erróneos sobre lo que significa la Transformación Digital. Es común que este concepto se enmarque en una serie de mitos que confunden y se transmiten voz a voz, creando un panorama de desinformación. Por eso, asumí el desafío de crear una estrategia digital que reúna en un solo lugar las dimensiones que forman parte de la TD. El objetivo es desmitificar las ideas preconcebidas de los empresarios para que puedan entender que su percepción de la realidad digital se ha creado bajo ideas que no corresponden a la verdad. Por lo tanto, para lograr este cambio de mentalidad, se utilizará un lenguaje común y directo con el fin de que las personas se sientan identificadas con sus ideas falsas sobre el concepto y, como resultado, experimenten el deseo de explorar más a fondo. Dentro de esta estrategia y como artefacto final, desarrollé un sitio web llamado ""Mitos Digitales"", los empresarios podrán comprender el concepto, sus componentes, beneficios, la tecnología más usada, historias de éxito y una recopilación de mitos desarticulados. Finalmente, podrán encontrar algunos recursos en términos de formación y ayuda financiera que el gobierno y las organizaciones privadas en Colombia están proporcionando para apoyar y fortalecer el crecimiento y desarrollo tecnológico de las pymes.

Resumen: La expresión “método socrático” es usada con regularidad en la literatura educativa, donde se discuten sus aplicaciones, virtudes y limitaciones. Sin embargo, no son tantos los esfuerzos que se hacen por precisar la noción misma de método socrático, en especial su relación con lo que sabemos del pensamiento de Sócrates. El objetivo de este capítulo es precisamente especificar este concepto, atendiendo a cuestiones como la posibilidad de convertirlo en un instrumento de enseñanza, su finalidad, los criterios para que un ejercicio pedagógico pueda ser considerado socrático y las condiciones para poder aplicarlo. Este objetivo se perseguirá mediante el rastreo de distintos elementos en algunos diálogos tempranos de Platón, los cuales serán contrastados con consideraciones presentadas por lecturas contemporáneas de los mismos. Abstract: The expression “Socratic method” is regularly used in the educational literature, where its applications, virtues and limitations are discussed. However, not so many efforts are made to specify the very notion of Socratic method, especially its relationship with what we know of Socrates’ thought. The aim of this chapter is precisely to specify this notion, addressing issues such as the possibility of turning it into a teaching tool, its purpose, the criteria for a pedagogical exercise to be considered Socratic and the conditions for its application. This objective will be pursued by tracing different elements in some of Plato’s early dialogues, which will be contrasted with considerations presented by contemporary readings of them.

Abstract: Reservoir models of deep-water channels rely upon low-resolution but spatially extensive seismic data, high vertical resolution but spatially sparse well log data and geomodeling methods. The results cannot predict architecture below seismic resolution or between well logs. Usually, the data and interpretations that provide constraints for modeling workflows do not capture sub-seismic scale architecture. Therefore, standard modeling methods do not generate models that include details that can impact hydrocarbon flow and recovery. Constraining models to well and seismic data is problematic. Employing measured sections in the Tres Pasos Fm. (Magallanes Basin, Chile) is feasible to predict deep-water channel architecture, specifically channel stacking patterns with 1D information analogous to well data. This research performed near-wellbore modeling to generate multiple scenarios of channel stacking patterns constrained by machine learning-derived probabilities using (i) conditional Monte Carlo simulation with soft probabilities per channel element within the measured section choosing the highest probabilities for each element (ii) conditional Monte Carlo simulation of channel stacking, (iii) template-based modeling, (iv) forward modeling with Markov transition probabilities without matching to thickness and (v) conditional Monte Carlo simulation constrained to measured section thickness. Machine learning workflows generate channel position probabilities (i.e., axis, off-axis, margin) within a measured section given the interpreted top/bases of channel elements. These probabilities constitute the input for Monte Carlo simulations capturing channel element stacking patterns at the measured section locations. The most likely 2D channel stacking pattern scenarios defined channel centerline points, and volumes of the individual channel elements can be generated connecting them. Surface-based modeling offers a way to depict reservoirs of hydrocarbons, water or low-enthalpy geothermal systems in which small-scale heterogeneity needs to be captured explicitly by bounding surfaces because it impacts fluid flow, improving our forecasts of resource exploitation. Furthermore, predicting heterogeneity controlled by depositional architecture is critical for transport and storage capacity in CO2 reservoirs. The dataset provided and the advent of these flexible and accurate methods to depict the subsurface offer the opportunity to overcome the historical limitations of grid-based models and allow us to assess multiscale architecture that controls fluid flow. This research aims to show the results of modeling deepwater channels, including a 1D identification of architectural positions and a 2D arrangement of channel stacking patterns.

Abstract: The supply chain is a network of nodes that connects the different states through which a raw material must go from the source to being a finished product available to the consumer. The intermediate nodes that help reduce the distances between the manufacturer and the customer when distributing products are called warehouses, distribution centres or cross-docks. These facilities serve as temporary storage that reduces distribution costs and allows products to be available closer to the customers when required. In many operations worldwide where automation is not an option as it is a costly alternative, these warehouses, distribution centres and crossdocks manually operate with workers their activities of loading, unloading, picking, sorting, storing, among others. This study seeks to address the workforce sizing problem in warehouses, distribution centres or cross-docks to understand what the indicated number of workers should be to meet the site's performance indicators, meet demand and reduce operating costs. The research was developed under a methodology with mixed methods, where from an exploratory sequential approach, it begins with a systematic literature review to find the most relevant variables or factors used by multiple studies when trying to address the problem of dimensioning the workforce in distribution centres, warehouses, or cross-docks, as well as contrast their approaches and identify the techniques and tools used. With this, a total of 46 variables were found by breaking down their frequency of appearance by journal article or conference proceeding, clustering them into 7 categories which are input and output operations, material handling equipment (MHE) performance, warehouse configuration, warehouse performance, product complexity, picking operations and labour and worker conditions. Based on these variables, some were used in the technique that most frequently appeared in the literature, simulation. Here, a crossdock of a company belonging to the mass consumption sector was virtually represented using Flexsim software. The objective of this simulation was to find the number of forklifts needed to handle the loading and unloading operation of 5 types of trucks under different demand scenarios, or the total number of trucks to attend per day. After developing the model and extracting the results for 4 demand profiles, a sensitivity analysis was carried out where the influence of the forklift quantity on the crossdock performance measures was demonstrated, finding that as the number of forklifts increased, the average truck cycle time decreased, the total quantity of trucks attended reached the expected number per day according to the demand profile, and the average forklift utilization decreased. Finally, the limitations were shown from the literature and from the simulation model to address the workforce sizing problem, giving suggestions for future research that can deepen or address the problem from another approach.

Abstract: The thesis critically deals with Urban Greening, a phenomenon that transformed contemporary urban areas in the post-industrial landscape. After a deep exploration of literature and field fieldwork, this research defines such an issue as “an accumulative mechanism of translation of the perception and relationship between society and urban nature”. By inquiring greening mechanisms in the cases of Rotterdam and Torino, the work proposes a design experiment to challenge the current ways of production of green bodies, by fostering new relationships in the urban sphere. The first part of the thesis defines urban greening through literature, contemporary definitions, and categorizations. Aiming for a redefinition of the concept by means of the deconstruction into its main components; society, nature, time, and interactions. The research directly moves towards a better understanding of what greening and nature can mean, by confronting the ideas of some significant authors, such as Matthew Gandy, Phillippe Descola, and Lucilla Barchetta, among others. The exploration understands the relevance of greening as a term that has gained momentum in the past few decades, with the decline of the post-industrial landscape and the increasing degradation processes of the Anthropocene. However, the general approach, wishes to go beyond the contemporary notions of greening, as one of the promises of the so-called “sustainable city”, and explore the constructions and narratives that have constituted its meaning throughout time. The second part of the inquiry takes two contemporary cities as case studies: Rotterdam and Torino. By analyzing their greening history and urban expansion, to later take a look at the modern-day panorama in terms of administration, governance, and policies around green infrastructures. Moreover, confronting this Greening agenda with the projects that will shape the future of Rotterdam and Torino, assessing their reach, coherence, and implementation in terms of the Sustainable City. As a result of the case studies exploration, the thesis draws a series of considerations that suggest new types of relationships around urban greening. The last part of the study wishes to challenge current ways of urban greening, by experimenting with a form of planning that drifts apart from the objectification of green elements and hopefully tries to integrate spontaneity in urban relationships.

Abstract: A growing number of information and communication technologies (ICTs) are being used worldwide to support participatory budgeting, a process that allows citizens to decide how to spend part of the public budget. Nevertheless, the effects of ICTs on political inclusion in participatory budgeting processes remain underexplored in the literature. This paper aims at contributing to the cited scholarship. The research takes the form of a qualitative case study of the participatory budgeting process in Medellín, Colombia’s second-biggest city, from its launch as a city-wide policy in 2004, until its last regulatory change in 2017. The article analyzes the influence of the use of ICTs in Medellín’s participatory budgeting process on political inclusion in the view of the process participants. The qualitative data collected suggests that ICTs can change the power dynamics in Medellín’s participatory budgeting process; nevertheless, their use has mixed results, depending on how they are designed and implemented.

Abstract: I document differences in inflation rates across gender in the UK between 2001 and 2021. Using data from the interview and diary components of the Living Costs and Food Survey, for the period spanning 2001-2021, I compute gender specific inflation rates for male and female households. I find that average annual inflation was higher for male than for female households (17 and 15 basis points higher for single and cohabitating male households than single and cohabitating female households, respectively). This difference persists after controlling for other sociodemographic characteristics. Differences are mainly explained by male households spending a significantly larger part of their consumption budget in relatively higher-inflation product categories, such as transport, restaurants and hotels, and alcohol and tobacco. Deflation in clothing and footwear, a category on which female households spent around twice as much as male households, further increased the gap. I also document a significant amount of heterogeneity in inflation within gender. Resumen: Documento las diferencias en las tasas de inflación por género en el Reino Unido entre 2001 y 2021. Utilizando datos de los componentes de entrevista y diario de la Living Costs and Food Survey del Reino Unido, para el periodo comprendido entre 2001 y 2021, calculo las tasas de inflación específicas por género para los hogares masculinos y femeninos. La inflación media anual fue mayor en los hogares masculinos que en los femeninos (17 y 15 puntos básicos, respectivamente). Esta diferencia persiste después de controlar otras características sociodemográficas. Las diferencias se explican principalmente por el hecho de que los hogares masculinos gastan una parte significativamente mayor de su presupuesto de consumo en categorías de productos que experimentaron una mayor inflación, como transporte, restaurantes y hoteles y alcohol y tabaco. La deflación en ropa y calzado, una categoría en la que las mujeres en la que los hogares femeninos gastan aproximadamente el doble que los masculinos.

Abstract: O-vacancies are defects commonly correlated with the production of CH4 by CO2 hydrogenation on reducible catalysts. Their effect on the stability of active COads and its origin is, however, not commonly explored for low Ru-loaded catalysts (Ru < 0.5 wt%). Herein, we investigated two catalysts containing a comparable amount of Ru (? 0.4 wt%) on two different zirconia supports: ZrO2 and ZrO2-MgO (2.6 wt%-MgO). The rate of CH4 formation on Ru/ZrO2-MgO is ca. 3-fold higher than on Ru/ZrO2. Combined results from various ex-situ and in-situ characterization techniques provide evidence supporting the correlation between methane evolution and the extended Ru-support perimeter as well as with changes in the bond strength of intermediates modulated by Ovacancies. This latter effect represents the main difference between the two catalysts since the replacement of Zr4+ by Mg2+ ions in the ZrO2 lattice promotes the generation of Ovacancies, facilitating electron transfer from them to interfacial Ru sites. This not only enhances H2 activation but also weakens the stability of adsorbed bidentate formate (b-HCOO- ads), which subsequently decomposes to COads and then hydrogenates to CH4 at the Ru-support perimeter.

Abstract: This paper analyzes some of the consequences that a perspective of economic growth based on the domain of what is usually called ""natural resources"" has for the Amazon Region and its socio-biodiversity. Through a critical analysis of academic literature and recent journalistic articles, it aims to contextualize the Amazon region and its importance for the planet, as well as show the scope of the deforestation problem and point out some of its consequences. In contrast to the ""exploitation of nature"" promoted by the capitalist system, which only benefits a minority of human beings to the detriment of a majority of other beings -human and non-human-and their environments, the worldview of Good Living developed by the Andean-Amazonian peoples and the decolonial perspective are highlighted. Good Living defends the need to respect all forms of life. Thus, it constitutes a possibility of establishing another relationship between all living beings and their environments and, as a consequence, an attempt to avoid the destruction of what remains of the Amazon rainforest and the possible appearance of other pandemics such as COVID-19 in that region. Resumen: Este artículo analiza algunas de las consecuencias que una perspectiva de crecimiento económico, por medio del dominio de lo que se suele denominar “recursos naturales”, tiene para la región amazónica y para su sociobiodiversidad. Desde un análisis crítico de literatura académica y de artículos periodísticos recientes, se pretende contextualizar la región amazónica y su importancia para el planeta, así como mostrar el alcance del problema de la deforestación y señalar algunas de sus consecuencias. Como contrapunto a la “explotación de la naturaleza” promovida por el sistema capitalista, que solo beneficia a una minoría de seres humanos en detrimento de una mayoría de otros seres –humanos y no humanos–y de sus ambientes, se destacan la cosmovisión del Buen Vivir desarrollada por los pueblos andino-amazónicos y la perspectiva decolonial. El Buen Vivir defiende la necesidad de respetar todas las formas de vida. Así, constituye una posibilidad de establecer otra relación entre todos los seres vivos y sus ambientes y, como consecuencia, un intento de evitar la destrucción de lo que queda de la selva amazónica y la posible aparición de otras pandemias similares a la de COVID-19 en esa región.
