Resumo A expansão desordenada das cidades é um desafio global que afeta o desenvolvimento urbano. Neste estudo, é analisado o crescimento urbano em uma cidade média durante cinco décadas, com enfoque na forma urbana e aplicação de mais de 20 métricas espaciais associadas à mensuração da geometria da expansão físico-territorial no ambiente construído. Os padrões de crescimento são analisados à luz do fenômeno espraiamento urbano e sob a perspectiva da teoria de Difusão-Coalescência. São discutidas as limitações inerentes às métricas existentes, assim como elencadas alternativas que as superam por mensuração das propriedades de Compacidade, Fragmentação, Complexidade e Dispersão concomitantemente. Os resultados demonstraram a ocorrência de fases distintas no crescimento urbano ao longo das décadas: Difusão de uma forma inicialmente compacta em partes menores nas periferias; e Transição para crescimento com agrupamento dessas partes, elevando a compacidade. Essa oscilação sugere aderência à teoria da Difusão-Coalescência, com ocorrência de espraiamento urbano (entre 1966 e 1976) seguida de aumento da compacidade nas décadas subsequentes (1976-2006). Após 2006 os resultados são ambíguos, possivelmente associados a fatores intervenientes de planejamento. A discussão dos resultados destaca a relevância da quantificação do crescimento urbano por meio de métricas, e traz conceitos importantes atualmente limitados à literatura internacional. estudo 2 físicoterritorial físico territorial construído DifusãoCoalescência.

Abstract The disorderly expansion of cities is a global challenge that impacts urban development. In this paper, we analyse the urban growth in a medium-sized city over five decades, focusing on urban form and employing more than 20 spatial metrics associated with the geometry of physical-territorial expansion in the built environment. We examine the growth patterns in the context of the urban sprawl phenomenon and the Diffusion-Coalescence theory perspective. We discuss the inherent limitations of existing metrics and raise alternatives that simultaneously address the properties of Compactness, Fragmentation, Complexity, and Dispersion. The results reveal distinct phases in urban growth over the decades, from diffusion of an initially compact form into smaller parts on the periphery; to a transition towards more compact growth. This oscillation suggests adherence to the Diffusion-Coalescence theory, with urban sprawl occurring between 1966 and 1976, followed by increased compactness in subsequent decades (1976-2006). After 2006, the results became ambiguous, possibly due to intervening planning factors. The discussion of the findings underscores the importance of quantifying urban growth using metrics and introduces concepts that have been hitherto limited to international literature. development paper mediumsized medium sized 2 physicalterritorial physical territorial environment DiffusionCoalescence Diffusion Coalescence perspective Compactness Fragmentation Complexity Dispersion periphery 196 1976 19762006. 19762006 2006 .

Resumen Introducción: la tuberculosis es una enfermedad infecciosa crónica causada por Mycobacterium tuberculosis, capaz de afectar cualquier órgano o tejido siendo la forma más común la enfermedad pulmonar. Objetivo: identificar los factores que afectan la adherencia al tratamiento antituberculoso en pacientes del Departamento de Boyacá durante los años 2017-2019. Metodología: estudio descriptivo retrospectivo que utilizó como fuentes de información datos registrados en la base del programa departamental de Tuberculosis y SIVIGILA. Se realizó análisis univariado, determinando la distribución de las variables y análisis bivariado en el que se exploró la asociación entre la adherencia al tratamiento de tuberculosis y las variables independientes, se utilizó la prueba de Chi cuadrado. Resultados: se incluyeron 402 pacientes, la adherencia al tratamiento antituberculoso fue 96,5% y la no adherencia de 3,5%. El 66,7% eran de sexo femenino; 55,7% vivián en zona urbana; 66,5% pertenecían al régimen subsidiado; 89,7% mestizos; 91,2% correspondían a otros grupos poblacionales, seguido del 7,5% de población privada de la libertad y 1,3% habitantes de calle. Dentro de las comorbilidades la coinfección con VIH con 4,2% fue la de mayor presencia. Entre las causas de no adherencia al tratamiento fueron desinterés, cambio frecuente de domicilio, contrato finalizado con la EPS y suspensión del tratamiento por toxicidad hepática. El paciente con mayor probabilidad de abandonar el tratamiento pertenece al sexo masculino, al grupo poblacional de migrantes o habitantes de calle y se encuentra afiliado al régimen subsidiado, se encontró una relación estadísticamente significativa entre estas variables y el resultado con la adherencia al tratamiento. Conclusiones: si bien el resultado obtenido en el presente trabajo no es elevado, es importante realizar vigilancia de la adherencia al tratamiento antituberculoso para disminuir el riesgo de complicaciones derivadas de su abandono como mayor mortalidad, desarrollo de resistencia bacteriana y un período de contagiosidad más prolongado.

Abstract Introduction: Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis, capable of affecting any organ or tissue, the most common form being lung disease. Objective: Identify the factors that affect adherence to tuberculosis treatment in patients from the Department of Boyacá during the years 2017-2019. Methodology: Retrospective descriptive study that used as information sources data registered in the database of the departmental Tuberculosis program and SIVIGILA. A univariate analysis was carried out, determining the distribution of the variables and a bivariate analysis in which the association between adherence to tuberculosis treatment and the independent variables was explored, using the Chi-square test. Results: 402 patients were included, adherence to anti-tuberculosis treatment was 96.5% and non-adherence 3.5%. 66.7% were female; 55.7% lived in an urban area; 66.5% belonged to the subsidized regime; 89.7% mestizo; 91.2% corresponded to other population groups, followed by 7.5% of the population deprived of liberty and 1.3% homeless. Within the comorbidities, coinfection with HIV 4.2% was the one with the greatest presence. Among the causes of non-adherence to treatment were lack of interest; frequent change of address; Terminated contract with the EPS and suspension of treatment due to liver toxicity. The patient with the highest probability of abandoning treatment belongs to the male sex, to the population group of migrants or street dwellers and is affiliated with the subsidized regime, a statistically significant relationship was found between these variables and the result with adherence to treatment. Conclusions: Although the result obtained in this study is not high, it is important to monitor adherence to tuberculosis treatment to reduce the risk of complications derived from its abandonment, such as increased mortality, development of bacterial resistance, and a longer period of contagiousness.

Abstract: The Linguistic Landscape, a relatively recent area of research, deals with the visible written form of languages in public space. The methodology of data collection involves photographing and documenting the distinct types of support, languages and their functions in urban space. Linguistic Landscape research usually considers the simultaneous presence of several languages or varieties and their relation to each other. However, within the so-called Spot German approach, not necessarily used for academic purposes, data collection can be carried out for a specific purpose, without documenting all visible signs. In this article, I discuss the characteristics, definitions, and differences between the approaches and briefly present the possible sources of data collection based on research conducted in different countries. In addition, I present as an example of application the case of the German language in its relation to the space near a German school and its influence on the linguistic landscape of the city in which it is located. Finally, I present pedagogical possibilities for exploring the linguistic landscape in language teaching, as it offers the opportunity to investigate the relationship of the city and people with the languages in their surroundings, as well as presenting numerous entries for didactic exploration.

Resumo: A Paisagem Linguística, área de pesquisa relativamente recente, trata da forma escrita das línguas visível no espaço público. A metodologia de coleta de dados engloba fotografar e documentar os diferentes tipos de suporte, de línguas e suas funções no espaço urbano. As pesquisas em Paisagem Linguística geralmente consideram a presença simultânea de várias línguas ou variedades e sua relação umas com as outras, porém, dentro da abordagem denominada Spot German , não necessariamente utilizada com fins acadêmicos, a coleta de dados pode ser realizada com um objetivo específico, sem documentação de todos os sinais visíveis. Assim, neste artigo, discorro sobre as características, definições e diferenças entre as abordagens e apresento brevemente as possíveis fontes de coleta de dados com base em pesquisas realizadas em diversos países. Além disso, trago como exemplo de aplicação a língua alemã em sua relação com o espaço próximo a um colégio alemão e sua possível influência na paisagem linguística da cidade na qual se encontra. Por fim, apresento possibilidades pedagógicas para explorar a paisagem linguística no ensino de línguas, que oferece oportunidade de investigar a relação da cidade e das pessoas com as línguas do entorno, da mesma forma que apresenta inúmeras entradas para exploração didática.

Abstract: The purpose of this article is to offer empirical evidence on the characteristics of demographic dynamics and physical expansion of urban development in Mexico between 1990 and 2020, in order to identify patterns of urban form and to contribute to the debate on the compact urban growth or sprawl. The general question is whether contemporary urbanization in Mexico has been compact or dispersed. To achieve this purpose and to answer the question, statistical and cartographic information from population and housing censuses are used. The general conclusion is that cities with compact or sprawl pattern coexist in Mexico. In the context of a decline in the country’s demographic dynamics, the share of the population residing in discontinuous settlements increased discreetly, an indicator of sprawl, and population density increased marginally, an indicator of compact urbanization. These results confirm the concentrated or sprawl pattern of urbanization in Mexico, where the intra-urban and intra-metropolitan organization of the population has been closely linked to the patterns of the urban housing market and has had an effect on the performance of urban labour and transport markets.

Resumen: El propósito de este artículo consiste en ofrecer evidencia empírica sobre las características de la dinámica demográfica y de la expansión física del desarrollo urbano en México entre 1990 y 2020, con el fin de identificar patrones de forma urbana y de contribuir al debate sobre la configuración compacta o dispersa del crecimiento. La pregunta general es si la urbanización contemporánea en México ha sido compacta o dispersa. Para lograr dicho propósito y contestar el cuestionamiento, se utiliza información estadística y cartográfica de los censos de población y vivienda. La conclusión general es que en México coexisten ciudades compactas y ciudades dispersas. En el marco de un descenso en la dinámica demográfica del país, la participación de la población que reside en asentamientos discontinuos se incrementó de manera discreta, indicador de la urbanización dispersa, además de que la densidad de población aumentó marginalmente, indicador de la urbanización compacta. Estos resultados matizan el patrón concentrado o disperso de la urbanización en México. La organización intraurbana e intrametropolitana de la población ha estado estrechamente relacionada con las modalidades del mercado urbano de vivienda y ha tenido efecto en el funcionamiento de los mercados urbanos de trabajo y de transporte.

BACKGROUND: Despite inpatient rehabilitation many stroke survivors struggle with community reintegration on returning home. The environment to which the stroke survivor returns affects and may limit participation in home and community-based activities. AIM: To describe stroke survivors' lived experiences of the environmental barriers and facilitators to community reintegration in an under resourced urban metropolitan sub-district in the Western Cape, South Africa. METHODS: A descriptive, qualitative study design with a phenomenological emphasis used semi-structured interviews to collect the data from purposefully selected stroke survivors who had been discharged for more than one year following inpatient rehabilitation. Supporting data were collected from interviews with two occupational therapists providing rehabilitation services to the stroke survivors. Deductive priori coding of semi-structured interviews with 11 stroke survivors, based on the environment subsystems described in the Person-Environment-Occupation-Performance (PEOP) model explored the barriers and facilitators to their community reintegration. FINDINGS: Of the six environmental sub systems in the PEOP model the systems and policy, access to information and health education, social determinants of health in the form of poor rehabilitation planning and loss of income as well as the built and natural environment presented the greatest barriers to the stroke survivor participants' community reintegration. However, reintegration was facilitated by social support and social capital, social determinants of health in the form of support groups as well as assistive technologies. CONCLUSION: Community reintegration continues to be a challenge for stroke survivors in an under-resourced urban sub-district due to environmental barriers associated with factors such as poor social support, inadequate implementation of policies and systems, poor compliance with home programmes, low socioeconomic status, poor access within the built and natural environment and inappropriate assistive devices. Several facilitators that occupational therapists can focus on to enable community reintegration included ensuring effective social support, access to community-based organisations, the introduction of home visits and provision of appropriate assistive devices. IMPLICATIONS FOR PRACTICE All stroke survivors must receive a comprehensive discharge plan to facilitate adequate access to continued rehabilitation and support for successful community reintegration. • There must be a specific referral to primary health care rehabilitation services on discharge from hospital. • Occupational therapists at community level have the responsibility to: o advocate for, or assist stroke survivors to self-advocate, the removal of inter-sectoral environmental barriers that limit their community reintegration and community participation, o where possible provide services in the home and involve midlevel workers when conducting home visits to enable successful reintegration into the home and resumption of occupational roles where possible, o look to other resources in their community that can assist in facilitating the community reintegration of stroke survivors to enable access to health, education, productive activities, and social and leisure participation opportunities, o improve their collaboration with the communities that they service.

Abstract Objective: Carried out a structural analysis to identify the variables that intervene in the strengthening of the short food supply chains in the Metropolitan Area of Xalapa, Veracruz, Mexico (ZMX). Methodology: A descriptive and correlational research was carried out, with a mixed approach, semi-structured interviews Results: The SFSC identified in the ZMX were characterized according to the type of proximity, temporality, type of production, size, form of organization, validity, type of initiative, the origin of the products, pricing strategy, and communication strategy with the consumers. In addition, it was identified that the key variables for the strengthening of the CCC in the ZMX are agroecological production, consumer education, governance, and diversity in the supply of local products. Limitations: The particularities of the context and the social actors generate constant changes in the development of the SFSC, for which reason the research registers a specific time. Conclusions: The SFSC plays a relevant role in territorial development, mainly for the link between the urban and peri-urban areas of the ZMX. Multi-stakeholder participation is important for its strengthening, and this can be linked to public program strategies that facilitate the creation and consolidation of SFSC in the region.

Resumen Esta contribución se enmarca dentro de la línea de investigación de la etnobotánica urbana que tiene como principal objetivo estudiar el conocimiento botánico en el ámbito urbano y periurbano. Este trabajo está orientado a conocer las etnoespecies (que incluyen especies vegetales y variedades botánicas locales) utilizadas por las familias bolivianas del cinturón hortícola de La Plata para la elaboración de sus platos típicos/cotidianos. El relevamiento se realizó en 6 ferias y 22 puestos de venta de hortalizas y frutas en el ámbito urbano, a partir de estos se realizaron 10 entrevistas abiertas y semiestructuradas a los vendedores/productores bolivianos en sus sitios de venta. Como resultado se identificaron 61 etnoespecies pertenecientes a 16 familias botánicas, tres de las cuales concentran la mayor cantidad de etnoespecies registradas: Solanaceae (13), Cucurbitaceae (8) y Brassicaceae (6); junto a la parte de la planta que se comercializa, siendo los frutos frescos a granel la forma predominante (59%). Esta contribución amplía el conocimiento de la dieta de los migrantes, los usos y la adaptación de su gastronomía. En conclusión, los vendedores informaron que emplean todas las etnoespecies que comercializan en su cocina diaria cumpliendo un rol importante dentro de su hogar, como así también sus cultivos que aumentan la agrobiodiversidad local.

Summary This contribution is part of the urban ethnobotany research line whose main objective is to study botanical knowledge in the urban and peri-urban environment. This work is oriented to know the ethnospecies (which include plant species and local botanical varieties) used by the Bolivian families of the La Plata horticultural belt for the elaboration of their typical/daily dishes. Six fairs and 22 vegetable and fruit sales stalls in the urban area were surveyed, three of which concentrate the largest number of registered ethnospecies: Solanaceae (13), Cucurbitaceae (8) and Brassicaceae (6); along with the part of the plant that is commercialized, being the fresh fruits in bulk the predominant form (59%). This contribution expands knowledge of the diet of migrants, the uses and adaptation of their gastronomy. In conclusion, the sellers reported that they use all the ethnospecies that they sell in their daily cooking, fulfilling an important role within their home, as well as their crops that increase the local agrobiodiversity.

Abstract: The unplanned and fragmented urban development of cities has caused them to be responsible for most of the planet's unsustainable development. Urban sustainability emerges as a response to this imbalance. Throughout its history, Guayaquil has shown unplanned urban growth that has continuously degraded its natural resources, such as forests and estuaries. The present research aims to evaluate the level of sustainability resulting from such change at the neighborhood level in Guayaquil. The study analyzes urban indicators of six representative neighbourhoods of the city regarding socioeconomic and historical factors. Thus, indicators were analyzed with respect to form, diversity, mobility, and environmental quality. The methodology includes an analysis for selecting variables, a study of the neighbourhoods' morphology using geo-portal map and information gathering through field studies and data processing. The results allow inferring the variables' influence on the sustainability level of each analyzed neighbourhood and how density, diversity and environmental quality play a vital role in developing greater sustainability at the neighbourhood and city levels.

Resumen: El desarrollo urbano no planificado y fragmentado de las ciudades ha ocasionado que estas sean responsables de la mayor parte del desarrollo no sustentable del planeta. La sostenibilidad urbana surge como medida de respuesta ante esta descompensación. La ciudad de Guayaquil presenta a lo largo de su historia un crecimiento urbano no planificado que continuamente ha degradado sus recursos naturales, como bosques y esteros. La presente investigación tiene como objetivo evaluar el nivel de sostenibilidad resultante de tal crecimiento a nivel barrial en Guayaquil. El estudio analiza indicadores urbanos de seis barrios representativos de la ciudad en cuanto a factores socioeconómicos e históricos. Se analizaron indicadores con respecto a la forma, diversidad, movilidad y calidad ambiental. La metodología utilizada recoge un análisis para la selección de variables, estudio de la morfología de los barrios realizada por medio de mapas de geo portales, relevamiento de información a través de estudio de campo y procesamiento de datos. Los resultados permiten inferir la influencia de las variables en el nivel de sostenibilidad de cada uno de los barrios analizados y como la densidad, la diversidad y calidad ambiental desempeñan un papel primordial en el desarrollo de una mayor sostenibilidad a nivel barrial y de ciudad.

ABSTRACT Urban growth in Latin American metropolises has adopted different spatial patterns and intensities, including a form of urban sprawl that is moving away from the core of the city. To address the negative consequences of such growth, states have established policies to control and guide expansive urban development, mainly through urban planning and land regulation. This study analyses the role of urban planning and regulation in the expansion of the city of Santiago de Chile between 1997 and 2013. The analysis employs coverage maps, the zoning established by the Metropolitan Regulatory Plan of Santiago and a review of applicable regulations. The main result shows that the city expands in areas declared as non-urban by the Plan, with an active role of the State in the establishment of norms that allow the expansion of the city, producing territorial normative contradictions.

RESUMEN El crecimiento urbano de las metrópolis latinoamericanas ha adoptado diferentes patrones espaciales e intensidades; entre ellos, una forma urbana que se da en expansión y crece hacia fuera del núcleo de la ciudad. Para hacer frente a las consecuencias negativas de tal crecimiento, los Estados han establecido políticas destinadas a controlar y orientar el desarrollo urbano expansivo, principalmente a través de la planificación urbana y la regulación del suelo. Este estudio analiza el rol de la planificación y normativa urbana en la expansión de la ciudad de Santiago de Chile entre 1997 y 2013, utilizando para ello mapas de cobertura, la zonificación establecida por el Plan Regulador Metropolitano de Santiago y una revisión de la normativa aplicable. Se demuestra que la ciudad se expande en aquellas zonas declaradas como no urbanas por el Plan, proceso en que el Estado desempeña un rol activo al establecer normas que permiten expandir la ciudad, produciendo contradicciones normativas territoriales.

ABSTRACT: The hydrothermal carbonization process has attracted the attention of the academic and scientific community as an emerging and ecological technology for the transformation of urban lignocellulosic waste into a source of bioenergy in solid form (hydrochar), liquid, and gases. This review addresses understanding the properties and potential use of these wastes as a source of bioenergy. The physicochemical and energetic properties of these wastes are analyzed, as well as the operating parameters that influence their transformation. Furthermore, new perspectives are presented on future challenges related to the potential use of this waste and the carbonization process. The sustainable conversion of these urban wastes into a source of bioenergy will contribute to reducing dependence on fossil fuels, minimizing greenhouse gas emissions, ensuring efficient urban waste management, and developing a circular bioeconomy.

RESUMEN: El proceso de carbonización hidrotérmica ha llamado la atención de la comunidad académica y científica como una tecnología emergente y ecológica para la transformación de los residuos lignocelulósicos urbanos en fuente de bioenergía en forma sólida (hidrocarbón), líquida y gaseosa. Esta revisión aborda la comprensión de las propiedades y el potencial uso de estos residuos como fuente de bioenergía. Se analizan las propiedades fisicoquímicas y energéticas de estos residuos, así como los parámetros de operación que influyen en su transformación. Además, se presentan nuevas perspectivas sobre los desafíos futuros relacionados con el uso potencial de estos residuos y el proceso de carbonización. La conversión sostenible de estos residuos urbanos en una fuente de bioenergía contribuirá a reducir la dependencia de los combustibles fósiles, minimizar las emisiones de gases de efecto invernadero, garantizar una gestión eficiente de los residuos urbanos y desarrollar una bioeconomía circular.

Abstract: The municipalities, faced with the obligation to generate property appraisals, have predominantly used the comparison method, characterized by submitting to the distortions of the land market, excluding the explicit consideration of factors that value it. This article presents a method of valuing urban land massively, based on the generation of land rents that value the property and that in its capitalized form are expressed in its price. Through the application in the city of Cuenca, a set of procedures is established for the determination of the base unit price, identifying for this the capital incorporated into the land in infrastructures and equipment, and quantifying the most relevant primary and secondary rents from the expressions of the spatial structure of land uses linked to their generation. The results obtained show that the theory of land rent is applicable to the massive valuation of urban land for cadastral purposes, obtaining a significant degree of understanding of the conformation of land prices in the city associated with their dynamics.

Resumen: Las municipalidades, frente a la obligatoriedad de generar avalúos prediales, predominantemente han empleado el método de comparación, caracterizado por someterse a las distorsiones del mercado de suelo, excluyendo la consideración explícita de factores que lo valorizan. En este artículo se expone un método de valuación masiva del suelo urbano basado en la generación de rentas de suelo que valorizan la propiedad y que, en su forma capitalizada, se expresan en su precio. A través de la aplicación en la ciudad de Cuenca, se establece un conjunto de procedimientos para la determinación del precio unitario base, identificando para ello el capital incorporado al suelo en infraestructuras y equipamientos, y cuantificando las rentas primarias y secundarias más relevantes a partir de las expresiones de la estructura espacial de los usos de suelo vinculadas a su generación. Los resultados obtenidos demuestran que la teoría de la renta de la tierra es aplicable a la valuación masiva del suelo urbano con fines catastrales, obteniendo un significativo grado de comprensión sobre la conformación de los precios del suelo en la ciudad asociados a sus dinámicas.

Abstract Throughout this work we address the concept of Sustainable Entrepreneurship that arises from Social Entrepreneurship and the Sustainable Development Goals in a context of major global crises and emergencies such as Climate Change and COVID-19, and relates as well with the change in the paradigm of consumption in which millennials and centennials seek to buy products made in a responsible way and that have the least possible impact on the ecosystem. We will provide examples of successful stories of sustainable entrepreneurs at a global level and the opportunities that this new form of business offers. We’ll also make reference to the importance of teaching this new business model in universities, particularly in business schools, a model that is conscious and responsible with the environment and that responds to the need for an urban economy that provides concrete development solutions for the community in which it is inserted and the city we need.

Resumen A lo largo del presente trabajo abordamos el concepto de Emprendedorismo Sostenible, que surge del Emprendedorismo Social y de los Objetivos de Desarrollo Sostenible en un contexto de grandes crisis y emergencias mundiales, como el Cambio Climático y COVID-19, sumado al cambio en el paradigma del consumo en el cual los millennials y centennials buscan comprar productos elaborados de forma responsable y que tengan el menor impacto posible en el ecosistema. Se brindarán ejemplos de casos de éxitos de emprendedores sostenibles a nivel global y de las oportunidades que esta nueva forma de negocios brinda, así como de la importancia de que desde los ámbitos universitarios, en particular desde las escuelas de negocios, se enseñe este nuevo modelo de negocios consciente y responsable con el ambiente y que da respuesta a la necesidad de una economía urbana que brinde soluciones concretas de desarrollo para la comunidad en la que está inserta y la ciudad que necesitamos.

Exemplos de casos de sucesso de empreendedores sustentáveis a nível global e das oportunidades que esta nova forma de negócio oferece, bem como a importância do ensino deste novo modelo nas universidades, em particular nas escolas de negócios, negócios conscientes e responsáveis com o meio ambiente e que respondam à necessidade de uma economia urbana que ofereça soluções concretas de desenvolvimento para a comunidade em que está inserida e para a cidade de que precisamos.

The research reported on in this article was mainly undertaken to determine the obstacles to the enhancement of critical thinking in the learning of history at Form 3 level in secondary schools in the Masvingo urban area of Zimbabwe, in terms of the rationale of developing the learners' critical thinking. The promotion of critical thinking abilities is vital in education, since doing so helps to improve the learners' academic performance, as well as aiding in producing graduates with a multiplicity of skills that are required in the 21st century job market and in society as a whole. We used semi-structured interviews and lesson observations to reach conclusions on what recommendations to make in addressing the research problem. Several factors were identified as hindering the learners' acquisition of critical thinking, including the learners' and teachers' lack of self-efficacy, motivation and the poor learning environment. In addition to reflecting on the possibility of improving the learning and teaching of critical thinking, we recommend that the Ministry of Primary and Secondary Education, Zimbabwe's Schools Examination Council, teacher training colleges and teachers should all work together to develop the learners' critical thinking skills within the parameters of the Zimbabwean education system.

Abstract The objective of this article is to demonstrate, using a squatted building located in the Brás neighborhood and organized by Brazilian and Latin American migrants, the way in which commuting, housing, and work are associated and interwoven. The article shows the constitution and organization of the squatted building, displays the protection network that was formed around the urban space, and explains the way in which a lawsuit that requires the eviction of families addresses the issue of work in the squatted building. Based on the dynamics of this urban space, we demonstrate that the form of work constituted in the squatted building fosters another market: the informal housing market. migrants commuting interwoven space market

Resumo O objetivo deste artigo é demonstrar, a partir de uma ocupação localizada no Brás, organizada por migrantes latino-americanos e brasileiros, a forma de associação e entrelaçamento entre deslocamento, moradia e trabalho. Demonstra-se o modo de constituição da ocupação e de organização do local, indicando a rede de proteção que se estabeleceu em torno do espaço urbano e como uma ação judicial, que requer a remoção das famílias, aborda o tema do trabalho no local. A partir da dinâmica desse espaço urbano, demonstra-se que o trabalho constituído na ocupação fomenta um outro mercado, o mercado tido como informal de moradia. demonstrar Brás latinoamericanos latino americanos brasileiros deslocamento Demonstrase Demonstra local judicial famílias demonstrase demonstra
