Abstract Introduction: Studies on the microsporogenesis of Rubus glaucus are non-existent and little is known about the ultrastructure of the pollen grains. Objectives: To describe the microsporogenesis process, and ultrastructural aspects of the pollen grains in Rubus glaucus. Methods: Flowers at different developmental stages were embedded in paraffin. Sections were stained with Safranin-Alcian Blue, PAS-Amidoblack and Lacmoid or included in resin and stained with toluidine blue. Ultrathin sections were examined by transmission electron microscopy (TEM). For scanning electron microscopy (SEM) observation, the material was fixed and dehydrated in 2.2 dimethoxypropane, then with Hexamethyldisilazane (HMDS), and the samples were coated with gold. Results: Anthers are differentiated by a cellular mass at the ends distal to the staminal filaments. During development, the anther wall presents several cellular layers and at maturity, they are reduced to the epidermis and the endothecium. Microsporocytes undergo simultaneous meiosis and form tetrahedral tetrads. The tapetum develops secretory activity until pollen grains are released, then the cellular content undergoes autolysis. During sporodermis formation, the exine is first deposited and then the intine in a centripetal form. The pollen grains are tricolporate, isopolar, oblate to peroblate, with radial simetry, circular in outline with blunt apices in polar view, ellipsoidal in equatorial view. The exine is thick, tectated, striate perforate. The sporodermis presents an ectexine formed by a tectum interrupted by perforations and thick columellae. Colpus membrane presents small exine granules and orbicules on the surface. The intine develops known structural patterns. Pollenkitt is inconspicuous. Conclusion: Anthers structure and development follows the known patterns of angiosperms. Simultaneous microsporogenesis and centripetal deposition of the sporodermis, as well as ornamentation patterns, have been previously described for the Rosaceae Family.

Resumen Introducción: Los estudios sobre la microsporogénesis de Rubus glaucus son inexistentes y poco es conocido sobre la ultraestructura del polen. Objetivos: Describir la microsporogénesis, y la ultraestructura de los granos de polen en Rubus glaucus. Métodos: Flores en diferentes etapas de desarrollo fueron incluidas en parafina o en resina. Las secciones se tiñeron con Safranin-Alcian Blue, PAS-Amidoblack y Lacmoid o incluidas en resina y teñidas con Azul de Toluidina. Secciones ultrafinas fueron observadas mediante microscopía electrónica de transmisión (MET). Para la observación con microscopía electrónica de barrido (MEB), el material se fijó y se deshidrató en 2.2 dimetoxipropano, luego se usó hexametildisilazano (HMDS) y las muestras se recubrieron con oro. Resultados: Las anteras se diferencian a partir de una masa celular en los extremos distales de los filamentos estaminales. Inicialmente, la pared de las anteras presenta varias capas celulares y al madurar se reducen a la epidermis y al endotecio. Los microsporocitos experimentan meiosis simultánea y forman tétradas tetraédricas. El tapete desarrolla actividad secretora hasta que se liberan los granos de polen, luego el contenido celular se desorganiza y experimenta autólisis. Al formarse la esporodermis, primero se deposita la exina y luego la intina en forma centrípeta. Los granos de polen son tricolporados, isopolares, oblados a peroblados, con simetría radial, de contorno circular con ápices romos en vista polar, elipsoidales en vista ecuatorial. La exina es gruesa, tectada, perforada estriada. La ectexina está formada por un tectum interrumpido por perforaciones y gruesas columelas. La membrana del colpo posee pequeños gránulos como restos de exina y orbículas en la superficie. La intina desarrolla patrones estructurales conocidos. El polenkit es inconspicuo. Conclusión: El desarrollo de las anteras sigue los patrones de las angiospermas. La microsporogénesis simultánea, el depósito centrípeto de la esporodermis, y los patrones de ornamentación observados han sido descritos previamente para la Familia Rosaceae.

Abstract Introduction: The River Tambo basin is one of the main hydrographic systems of the Peruvian western watershed, being a source of development for agriculture, agroindustry, livestock, and domestic use in the Tambo Valley and Arequipa City. Objective: To analyze the structure of macroinvertebrates in River Tambo, Perú and assess the water quality through this community. Methods: Five sampling events were conducted between December 2018 and November 2019 in 12 stations, using a Surber net (500 μm). Macroinvertebrates were identified at a family level. To assess community structure, richness, Simpson’s dominance index (D), Pielou’s evenness (J’), and true diversity of order 1 were determined. A nMDS based on the Bray-Curtis index was used to evaluate dissimilarity. To check for differences in community structure, ANOSIM and two-way MANOVA were used. SIMPER was used to establish family contribution to sample similarity. Relations between physicochemical and biological variables were determined by CCA. ABI index was applied to assess ecological quality. Results: 32 families were recognized, being the most abundant: Baetidae, Chironomidae, Leptohyphidae, Simuliidae, Hydroptilidae, and Elmidae. The middle and low zones of the basin showed the highest and lowest diversity respectively. There were significant differences (P < 0.05) in the community structure indices among the 12 stations differed. There was a higher similarity among the 12 stations in December. ABI scores increased from the low to the middle part of the river, which showed the highest ecological quality. Conclusion: Macroinvertebrate communities from River Tambo reflect ecosystem conditions. Environments impacted by human activities show lower diversity and ecological quality, due to the structure, habitat, and water quality of the river being altered.

Resumen Introducción: La cuenca del rio Tambo es uno de los principales sistemas hidrográficos de la vertiente occidental del Perú y fuente de desarrollo para la agricultura, agroindustria, ganadería y consumo doméstico en el valle de Tambo y la ciudad de Arequipa. Objetivo: Analizar la estructura de macroinvertebrados en el río Tambo, Perú y evaluar la calidad del agua a través de esta comunidad. Métodos: Entre diciembre del 2018 y noviembre del 2019 se realizaron cinco muestreos en 12 estaciones, empleando una red Surber (500 μm). Los macroinvertebrados se identificaron a nivel de familia. Se registró la riqueza, dominancia de Simpson, equidad de Pielou, y diversidad verdadera de orden 1, para evaluar la estructura de la comunidad. Para estimar la similitud, se utilizó nMDS (índice de Bray-Curtis). Para verificar si existen diferencias en la estructura comunitaria, se empleó MANOVA de dos vías y ANOSIM. Para establecer la contribución de las familias a la similitud entre muestras, se utilizó SIMPER. La relación entre variables fisicoquímicas y biológicas se determinó con ACC. Se aplicó el índice ABI para evaluar la calidad ecológica. Resultados: se reconocieron 32 familias, siendo las más abundantes: Baetidae, Chironomidae, Leptohyphidae, Simuliidae, Hydroptilidae y Elmidae. La mayor y menor diversidad se presentó en la parte media y baja de la cuenca respectivamente. Existieron diferencias significativas (P < 0.05) de los índices de estructura comunitaria entre las 12 estaciones. Se evidenció mayor similitud entre las 12 estaciones en diciembre. Los puntajes del índice ABI se incrementan de la parte baja del río a la media, que se presentó la mejor calidad ecológica. Conclusión: Las comunidades de macroinvertebrados del río Tambo reflejan el estado del ecosistema. Los ambientes con impacto por actividad humana registran menor diversidad y calidad ecológica, ya que se altera la estructura, hábitat y calidad de agua del río.

Resumen Antecedentes: Las especies de la familia Podostemaceae poseen rasgos inusuales en angiospermas. Crecen sumergidas en ríos de corriente fuerte y su ciclo de vida está ligado a la estacionalidad. Debido a su estructura floral reducida, el análisis de las etapas de desarrollo y eventos como la antesis o la receptividad del estigma ha sido complicado. Pregunta: ¿Cuál es la relación entre la morfología, el desarrollo y la receptividad del estigma en diferentes etapas del desarrollo de la flor de Marathrum rubrum? Especie de estudio: Marathrum rubrum Novelo & C. T. Philbrick. Sitio y años de estudio: Río Horcones, Jalisco, México. Enero 2014 y 2015. Métodos: Se realizó un análisis in situ y en laboratorio de la morfología floral de M. rubrum para evaluar la relación entre la morfología y desarrollo floral, y la receptividad del estigma en distintas etapas. Resultados: Cuando las flores emergen de la espatela, los óvulos y el polen están completamente desarrollados, por ello, la esporogénesis y la gametogénesis ocurren dentro del tallo, estando las plantas aún sumergidas. Conclusiones: Los cambios morfológicos observados en las flores de M. rubrum durante las etapas analizadas se relacionan únicamente con eventos asociados con la fecundación y el desarrollo del fruto. Las observaciones detalladas de la biología reproductiva de M. rubrum en el ambiente aéreo tienen importantes implicaciones para el conocimiento básico de la biología de las plantas de esta familia, la estructura genética de las poblaciones, el éxito reproductivo y la biología de la conservación en ambientes amenazados.

Abstract Background: Podostemaceae is the largest family of strictly aquatic angiosperms. Species of this family possess unusual morphological and reproductive characters, grow attached to rocks in rivers with strong currents, and have a life cycle tightly linked to seasonality. Due to its reduced floral structures, which characterizes most species, the analysis of developmental stages and events such as anthesis or stigma receptivity has proven difficult. Question: How floral morphology, floral development and stigma receptivity of different stages of flower development of Marathrum rubrum Novelo & C. T. Philbrick are related among them? Studied species: Marathrum rubrum Novelo & C. T. Philbrick. Study site and dates: Horcones River, Jalisco, Mexico. January, 2014 and 2015. Methods: We made an in situ and lab analyses of flower morphology to assess the relationships between flower morphology, stages of development, reproductive structures, and stigma receptivity, during different stages of flower development. Results: When flowers emerge from the spathella, both the ovules and pollen grains are fully developed, implying that sporogenesis and gametogenesis take place within the stem while the plant is still submerged. Conclusions: The morphological changes observed in the flowers of M. rubrum during the analyzed stages are related only to events associated with fertilization and fruit development. The time-course of morphological changes in the flowers, from anthesis to fruit formation, lasts 20 to 30 days. The detailed observation of the aerial reproductive biology of M. rubrum bears important implications to the genetic structure of populations, plant fitness and conservation biology in threatened environments.

Resumen Antecedentes: La información sobre las comunidades templadas es insuficiente, y esto se manifiesta de manera particular en el estado de Michoacán. Preguntas: ¿Cómo está constituido un ecosistema templado establecido en el Cinturón Volcánico Transmexicano (CVTM) en relación con su composición, estructura y diversidad? Sitio y años de estudio: El análisis se llevó a cabo en el otoño e inverno del 2018 en el Parque Nacional Barranca del Cupatitzio en Uruapan, Michoacán, México. Métodos: En 18 parcelas de 0.1 ha (20 × 50 m) se registraron plantas leñosas con un diámetro a la altura de 1.3 m (DAP) ≥ 2.5 cm y se registró el número de individuos y tallos, área basal, cobertura de copa, altura total, la diversidad alfa y se agruparon las unidades con técnicas multivariadas. Resultados: En 1.8 ha se registraron 55 especies, en 42 géneros y 32 familias. Pinaceae fue la más diversa (8) seguida de Asteraceae (9). La densidad (500-1,330 ind. ha-1), los tallos (650-3,040 ind. ha-1), la cobertura (10,999-46,390 m2ha-1), el DAP (9.2-18.9 cm), la altura (6.5-12 m) y la riqueza (6-17) varían entre parcelas. El 75 % del área basal (20.1 m2 ha-1) fue aportada por los pinos, los encinos contribuyeron con el 14 % (3.6 m2 ha-1) y el 11 % fue de otras especies (2.9 m2 ha-1). Conclusiones: Los ecosistemas forestales del parque mantienen propiedades ecológicas características de los bosques templados del CVTM. Este estudio sirve como punto de referencia para establecer metas de restauración ecológica en el parque explícitamente cuantificables.

Abstract Background: Information about temperate communities is insufficient, and this is particularly evident in the state of Michoacán. Questions: How is a temperate ecosystem established in the Trans-Mexican Volcanic Belt (TMVB) organized in terms of its composition, structure, and specific diversity? Study Site and Date: The analysis was conducted in the fall and winter of 2018 in the Barranca del Cupatitzio National Park in Uruapan, Michoacán, Mexico. Methods: In 18 plots of 0.1 hectares (20 × 50 m), woody plants with a diameter at breast height (DBH) ≥ 2.5 cm were recorded. Information was collected on the number of individuals and stems, basal area, canopy cover, height, alpha diversity, and units were grouped using multivariate techniques. Results: In 1.8 hectares, 55 species were recorded, belonging to 42 genera and 32 families. Pinaceae was the most diverse family with 8 species, followed by Asteraceae with 9 species. Density (500-1,330 individuals per hectare), stems (650-3,040 per hectare), canopy cover (10,999-46,390 m2 ha-1), DBH (9.2-18.9 cm), height (6.5-12 m), and species richness (6-17) varied among plots. 75 % of the basal area (20.1 m2 ha-1) was contributed by pines, oaks contributed 14 % (3.6 m2 ha-1), and 11 % came from other species (2.9 m2 ha-1). Conclusions: The forest ecosystems in the park exhibit ecological properties typical of temperate forests in the TMVB. This study serves as a reference point for establishing quantifiable ecological restoration goals in the park.

RESUMEN Sin lugar a dudas, la educación con enfoque de género se convierte en un imperativo para instituciones y organismos nacionales e internacionales encargados de estas acciones formativas. En ese sentido, se enfocan bases legales en República Dominicana que declaran la igualdad de género. Sin embargo, la práctica indica la necesidad de ahondar en las representaciones de la temática en los docentes en torno a su desempeño profesional y convoca a la búsqueda de sus referentes teóricos para intervenir. En esa dirección este artículo pretende socializar la propuesta interventiva de una estrategia pedagógica orientada a promover el enfoque de género en las instituciones educativas de la República Dominicana desde la preparación del docente. Desde un enfoque cualitativo, se sistematizan referentes esenciales y se constata la problemática en la práctica a partir de entrevistas, encuestas y observaciones, los que ofrecieron información pertinente para estructurar las etapas y acciones, en función de favorecer cambios en las instituciones educativas, que coadyuvaran a identificar y superar la educación sexista, fomentar vínculos equitativos entre los sujetos en el contexto escolar, familiar y social. La percepción medular en la preparación del docente contribuyó al desempeño profesional coherente con significativas transformaciones.

ABSTRACT Without a doubt, gender-focused education becomes an imperative for national and international institutions and organizations in charge of these training actions. In this sense, legal bases in the Dominican Republic that declare gender equality are focused on. However, practice indicates the need to delve into the representations of the subject in teachers around their professional performance and calls for the search for their theoretical references to intervene. In this direction, this article aims to socialize the intervention proposal of a pedagogical strategy aimed at promoting the gender approach in educational institutions in the Dominican Republic from the preparation of teachers. From a qualitative approach, essential references are systematized and the problem is verified in practice from interviews, surveys and observations, which offered pertinent information to structure the stages and actions, in order to favor changes in educational institutions, which will help to identify and overcome sexist education, promote equitable links between subjects in the school, family and social context. Core perception in teacher training contributed to professional performance consistent with significant transformations.

BACKGROUND: Maintaining or promoting employment in the presence of disability or reducing the impact of disability on employability should be the adopted focus to decrease the negative impact that disability has on the economy and just as important on the livelihood and well-being of exposed insured individuals. Group risk disability insurance protects an employee's income when illness or injury result in work disability. To achieve this, factors that promote the success of rehabilitation and support for return-to-work of employees following illness and injury need to be understood from an insurance perspective. OBJECTIVES: To explore principles of disability claims management during the rehabilitation and work reintegration stage using a multi-stakeholder approach for the purpose of successful return to work. METHODS: An exploratory qualitative design was used to collect data via semi-structured interviews with 26 purposively selected participants. Interviews were audio-recorded, data were transcribed and analysed thematically. Qualitative research was used to understand the necessary role players in the work reintegration process, factors that hinder and promote work reintegration and best practice principles for Disability Claims Management (DCM). RESULTS: Three themes emerged from the study; (i) role players and their functions with collaboration is integral to disability claims management, (ii) various factors promote and restrict return-to-work planning, and (iii) best practice principles in the DCM pathway that promote return-to-work. These principles include behavioural economics as the central principle, with resource identification and competency, governance, role engagement and education and awareness as supporting principles. CONCLUSION: Collaborative and integrated approaches by role players within a workers' family unit, health system, employer structure and insurance compensation are required for positive return-to-work outcomes. The various role players are responsible for creating policies, structures, intervention strategies, and environments that foster return-to-work. IMPLICATIONS FOR PRACTICE • An integrated approach is required for optimal RTW outcomes as employers' policies restrict work integration. • A collaborative approach by all role players involved in DCM, focusing on positive RTW outcomes is required in the RTW process • Occupational therapists can influence employer incapacity and disability policies in order to keep people employed and productive in the presence of medical conditions with the application of reasonable accommodations where necessary. • Occupational therapists are suitably positioned to outline workplace environment and other supports required to guide and support employees through rehabilitation and RTW and in ensuring that employees who can remain at work while on a partial or fully insured benefit, can engage optimally in aspects of work function.

Abstract Understanding forest structure and diversity allows the development and analysis of strategies for the sustainable management of natural resources. The objective of the research was to contribute to the knowledge of tree structure, as well as its regeneration capacity in an altitudinal gradient in a Natural Protected Area in Madera, Chihuahua. The study included three altitudinal intervals: lower (2 307 to 2 466 m), middle (2 466 to 2 625 m) and upper (2 625 - 2 785 m), in which 30 circular sites of 500 m2 were distributed where the diameter and height of the upper trees were measured, as well as the density of regeneration. The vertical structure was obtained with the Pretzsch index (A), in addition, the importance value index (IVI), diversity with the Shannon-Wiener index (H') and richness with Margalef (D mg ) were evaluated, as well as the renewal capacity and damage present. The values of A show the greatest structural homogeneity in interval 2; the Pinaceae family registered the highest ecological weight in the IVI; the values of H' and Dmg were higher in stratum II, however, all are considered of low diversity and richness; the species Abies concolor and Pseudotsuga menziesii, showed the highest proportion of regeneration in the community, in which suppression is the frequent damage, however, 95% of the individuals were not affected. This information is useful for the conservation of these ecologically important communities in temperate forests.

Resumen Comprender la estructura y diversidad forestal permite elaborar y analizar estrategias para el manejo sustentable de los recursos naturales. El objetivo de la investigación fue contribuir al conocimiento de la estructura arbórea, así como su capacidad de regeneración en un gradiente altitudinal en un Área Natural Protegida, en Madera, Chihuahua. El estudio comprendió tres intervalos altitudinales: inferior (2 307 a 2 466 m), medio (2 466 a 2 625 m) y superior (2 625 - 2 785 m), en los que se distribuyeron 30 sitios circulares de 500 m2 donde se midió el diámetro y altura del arbolado superior, así como la densidad de la regeneración. La estructura vertical se obtuvo con el índice de Pretzsch (A), además, se evaluó el índice de valor de importancia (IVI), la diversidad con el índice de Shannon-Wiener (H’) y riqueza con Margalef (D mg ), asimismo, se estimó la capacidad de renuevo y los daños presentes. Los valores de A muestran la mayor homogeneidad estructural en el intervalo 2; la familia Pinaceae registró el peso ecológico superior en el IVI; los valores de H’ y D mg fueron superiores en el estrato II, sin embargo, todos se consideran de baja diversidad y riqueza; las especies Abies concolor y Pseudotsuga menziesii, mostraron la mayor proporción de regeneración en la comunidad, en la que la supresión es el daño frecuente, no obstante, el 95% de los individuos no presentaron afectaciones. Esta información es de utilidad para la conservación de estas comunidades de importancia ecológica en bosques templados.

Abstract The ‘Blue Book’: a Future for Family Medicine in Portugal, edited in 1990 by the Portuguese Association of General Practice and Family Medicine, influenced the subsequent years and built the foundation for the Primary Healthcare Reform, initiated in 2005, but not fully implemented. In the current moment of low professional satisfaction, reviewing the principles that should guide family medicine in the future is important. The family doctor is the individual’s physician, who accompanies people's health throughout their life. Family doctors are specialists in primary healthcare and act according to the core values of family medicine as defined by the WONCA. Their actions form the basis of the health system and are associated with better health outcomes. Therefore, their actions must be centred on the person and the provision of differentiated care, reducing bureaucratic tasks and those with low health value. Physical spaces, equipment, and human resources should be adequately ensured, including the adjustment of the size of patients’ lists to ensure quality and dignified work by the Family Doctor, in every working setting. The Portuguese Association of General Practice and Family Medicine advocates for a performance-based remuneration model appropriate to the family doctor’s activity that compensates and prioritizes value-based healthcare, focusing their actions on the individual and reducing inefficiencies and duplications. This model is based on a new, simplified, and modern quality system grounded in the classic Structure - Process - Results framework but considering the dimensions of patient and professional satisfaction and adequately rewarding clinical work, teamwork, and citizen-centeredness. The present document is an adaptation and translation into English of the book 'A New Future for General and Family Medicine', edited by the Portuguese Association of General Practice and Family Medicine, in 2023.

Resumo O Livro Azul: um futuro para a Medicina de Família em Portugal, editado em 1990 pela Associação Portuguesa de Médicos de Clínica Geral, marcou os anos seguintes e conceptualizou a Reforma dos Cuidados de Saúde Primários, iniciada em 2005, mas não implementada na totalidade. No momento atual de insatisfação profissional é importante rever os princípios que nortearão a medicina geral e familiar no futuro. O médico de família é Médico da Pessoa. É nessa condição que faz o acompanhamento médico ao longo da sua vida. É especialista em cuidados de saúde primários e atua de acordo com os valores da medicina de família definidos pela WONCA. A sua ação é a base do sistema de saúde em que atua e está associada a melhores resultados de saúde. É, por isso, fundamental que a sua ação seja centralizada na pessoa e na prestação de cuidados diferenciados a esta, reduzindo as tarefas burocráticas e de baixo valor em saúde. Devem ser dadas condições materiais, de espaços físicos e de recursos humanos, incluindo adequação do tamanho das listas para garantir um trabalho digno e de qualidade ao médico de família. A APMGF defende um modelo de remuneração pelo desempenho adequado à atividade do médico de família que compense e priorize o valor em saúde, que centre a sua ação na pessoa e que reduza as ineficiências e duplicações. Este modelo assenta num novo sistema da qualidade simplificado e moderno assente no clássico Estrutura - Processo - Resultados, mas que considere as dimensões de satisfação de utentes e profissionais e que compense adequadamente o trabalho clínico, em equipa e centralidade do cidadão. O presente documento é uma adaptação e tradução para inglês do livro “Um Novo Futuro para a Medicina Geral e Familiar”, editado pela Associação Portuguesa de Medicina Geral e Familiar, em 2023.

Abstract When a building is demolished, its cohesive and planned structure fractures into countless fragments. These heterogeneous and disorganised fragments blur the boundaries between what was once private - the domestic space - and what is now public - the formerly occupied land. In 2019, I stumbled upon a family photograph amidst the rubble left by the demolition of the last towers of the Bairro do Aleixo in Porto. Constructed in the 1970s, this was a public housing estate designed to accommodate families from Ribeira-Barredo who had been displaced due to urban redevelopment. Throughout the years, the five towers have hosted a sizable and fluctuating population that has adapted and made use of this previously unconventional housing model. From 2011 to 2019, Aleixo underwent three demolition operations, politically supported by arguments citing its structural and social deterioration as justification. The first two were striking implosions broadcasted on television, whereas the final demolition, which I witnessed, unfolded as a slow deconstruction spanning several months. In the photograph, the woman dressed in white poses on a balcony of Tower 1 within the old Bairro do Aleixo. In the background stands the phallic skeleton of Tower 4, which would be imploded decades later. Upon its unearthing, the photograph, weathered by time and circumstance, hinted at a conceptual connection with the debris surrounding it. In this article, my focus centres on this found photograph, aiming to unveil the processes and tensions encapsulated within this fragment. I draw on the ontological connections between photography and death, as well as between photography and ruin, to analyse the spectral image of this obliterated site. I delve into what the encounter with this image might reveal about the memory of the neighbourhood, its public image, and the extensive and violent process of displacing its residents. I reach the concept of a "rubble-image" as pivotal in interpreting this nearly vanished imprint that stubbornly affirms the persistence of a dissenting and complex place, supposedly erased from public space and suppressed from urban memory by dominant sensibilities.

Resumo Quando uma edificação é demolida, a sua estrutura, unitária e planeada, é desintegrada em incontáveis fragmentos. Heterogéneos e desordenados, estes fragmentos borram os limites entre o que era privado - o espaço doméstico - e o que é público - o terreno antes ocupado. Em 2019, encontrei uma fotografia familiar entre os escombros da demolição das últimas torres do Bairro do Aleixo, no Porto. Este foi um conjunto de habitação pública construído na década de 1970 para realojar famílias da Ribeira-Barredo, deslocadas por uma reabilitação urbana. Ao longo do tempo, as cinco torres abrigaram uma população numerosa e mutável que se apropriou desse modelo de habitação até então incomum. Entre 2011 e 2019, o Aleixo foi alvo de três operações de demolição, politicamente justificadas por sua degradação estrutural e social. As duas primeiras foram implosões espetaculares e televisionadas, enquanto a última, que presenciei, foi uma lenta desconstrução que durou meses. Na fotografia, uma mulher vestida de branco posa numa varanda da Torre 1 do antigo Bairro do Aleixo. Ao fundo, paira o esqueleto fálico da Torre 4, implodida décadas depois. Quando encontrada, a fotografia, arruinada pelo tempo e pelas circunstâncias, sugeria uma afinidade conceptual com os escombros que a cercavam. Neste artigo, detenho-me sobre essa fotografia encontrada, objetivando desvelar os processos e as tensões armazenadas nesse fragmento. Recorro às relações ontológicas entre fotografia e morte, também entre fotografia e ruína, para analisar a imagem espectral desse sítio obliterado. Desenvolvo o que o encontro com ela pode indicar sobre a memória do bairro, a sua imagem pública, assim como o longo e violento processo de remoção dos seus moradores. Chego à noção de “imagem-escombro” como chave de leitura para esse vestígio quase desaparecido que afirma teimosamente a persistência de um lugar dissidente e complexo, pretensamente apagado do espaço público e suprimido da memória urbana pelas sensibilidades dominantes.

Abstract The objective of this work was to analyze the relationship between perceptions and agricultural practices in the face of the effects of climate change from the agro-socio-economic context and the hydrological structure in the Cochapata high-altitude ecosystem in Urcuquí-Ecuador. The methodological strategy responds to the qualitative paradigm, case study method. Primary information was collected through landscape reading, interviews, and participant observation. It was found that the territory is occupied by timber industries, whose tree species are characterized by excessive water demand. The sub-paramo is inhabited by peasants in survival conditions who use the land to obtain goods for family sustenance using their labor force. Water distribution is of a hydro-social nature, as it excludes peasants from the right to irrigation and watering. Regarding the effects of the changing climate, the inhabitants perceive heat waves and variations in the rainy season in their daily lives; however, no agricultural practices were found to adapt to the climatic phenomenon. It is concluded that the vulnerability of the ecosystem is not directly related to climate change; it responds to historical failures in the distribution of ecosystem goods such as land and water, to the lack of knowledge of the peasant subject on the part of the state and society, and the excessive extractivism implemented during the last decades.

Resumen El objetivo de este trabajo fue analizar la relación entre percepciones y prácticas agrícolas frente a los efectos del cambio climático desde el contexto agro-socio-económico y la estructura hidrológica en el ecosistema de altura Cochapata en Urcuquí-Ecuador. La estrategia metodológica responde al paradigma cualitativo, método de estudio de caso. Se levantó información primaria mediante lectura del paisaje, entrevistas y observación participante. Se encontró que el territorio está ocupado por industrias madereras cuyas especies arbóreas se caracterizan por excesiva demanda hídrica. El subpáramo está habitado por campesinos en condición de sobrevivencia que usan la tierra para obtener bienes de sustento familiar, valiéndose de su fuerza de trabajo. Se evidenció que la distribución del agua es de carácter hidrosocial, pues excluye al campesinado del derecho a riego y abrevadero. Respecto a los efectos del clima cambiante, los pobladores perciben en su cotidianidad olas de calor y variaciones en las temporadas de lluvias, sin embargo, no se encontraron prácticas agrícolas con intención adaptativa al fenómeno climático. Se concluye que la vulnerabilidad del ecosistema no guarda relación directa con el cambio climático, esta responde a las fallas históricas en la distribución de los bienes ecosistémicos tierra y agua, al desconocimiento del sujeto campesino por parte del Estado y de la sociedad, y al excesivo extractivismo implantado durante las últimas décadas.

Abstract During the Inka period, the populations from the Calchaquí valleys engaged in economies where the production, distribution, and consumption of goods occurred on both family and community levels, and within the larger framework of an imperial political economy, in which activities and services were subordinated to a hierarchical social integration in a previously non-existent structure. This differential participation can be evidenced through various material remains and may be observed at multiple scales. We argue that the preparation and consumption of food and drink materialize different types of social relationships and provide a valuable line of evidence for examining the two spheres of economic participation. In this paper, we carry out an initial exploration of this issue by studying organic residues preserved in six ceramic vessels from the archaeological sites of Tolombón, Pukará, and Tambo de Angastaco (Salta, Argentina) employing gas chromatography coupled with mass spectrometry. Additionally, 22 current food species from the study area were analyzed to create a more accurate comparative reference collection than those currently available. The results suggest different uses for the ceramic morphological types analyzed in the contexts of domestic and state-scale food practices in these settlements.

Resumen Durante el período Inka las poblaciones de los valles Calchaquíes participaron en economías donde la producción, distribución y consumo de bienes se dio tanto a escala familiar y/o comunitaria como en el marco de una economía política imperial, en que las actividades y servicios estuvieron supeditados a una integración social jerárquica dentro de una estructura previamente inexistente. Esta participación diferencial puede observarse a través de diversas materialidades y a diferentes escalas. Aquí partimos del supuesto que la preparación y consumo de comida y bebida materializan diferentes tipos de relaciones sociales y constituyen una línea de evidencia a través de la cual podemos observar estas dos esferas de participación. En este trabajo realizamos un primer acercamiento al problema a través del estudio de residuos orgánicos preservados en seis vasijas cerámicas procedentes de los sitios arqueológicos de Tolombón y Pukará y Tambo de Angastaco (Salta, Argentina) aplicando cromatografía gaseosa acoplada a espectrometría de masa. Asimismo, se analizaron 22 especies alimenticias actuales de la zona de estudio a fin de contar con una colección de referencia comparativa más adecuada que las disponibles actualmente. Los resultados obtenidos sugieren que existió una variabilidad de usos para los distintos tipos morfológicos cerámicos analizados en contextos de prácticas alimentarias a escala doméstica y estatal en los asentamientos investigados.

Abstract The objective was to know the population structure of Holstein animals in the family dairy system, to identify possible origins of the genetic material, to know the degree of inbreeding and to identify possible traces of selection in the genome, which allow glimpses of the traits that have been improved over the years. The study included 270 animals genotyped with the GGP-50K® chip. After genotype quality control, 43,548 autosomal SNPs were included. To know the population structure, analyses of mixtures and principal components (PCs) were performed. To know genomic inbreeding and detect traces of selection, information on runs of homozygosity (ROH) was used. Mixture analysis was performed with the Admixture software, and PC, ROH and inbreeding analyses were performed with SVS-v7.6.8. Mixture analysis showed evidence of six components, all linked to Holstein bulls families with different country of origin. The PCs did not show stratification of the population by herd. The mean inbreeding coefficient was 0.59 ± 0.53 %. In the regions of the genome with ROHs most frequent in the population (≥20 animals), numerous associations, QTLs and genes related to milk production and composition, fertility parameters, susceptibility to diseases, body conformation, feed efficiency and some characteristics of carcass composition have been reported. The results reflect the existence of a wide genetic diversity in this population and the possibility of carrying out genetic improvement work through selection without affecting inbreeding levels.

Resumen El objetivo fue conocer la estructura poblacional de los animales Holstein del sistema de lechería familiar, identificar posibles orígenes del material genético, conocer el grado de consanguinidad e identificar posibles huellas de selección en el genoma, que permitan vislumbrar las características que se han mejorado a través de los años. El estudio incluyó 270 animales genotipados con el chip GGP-50K®. Después del control de calidad de genotipos, se incluyeron 43,548 SNP autosómicos. Para conocer la estructura poblacional se realizaron análisis de mezclas y componentes principales (CP). Para conocer la consanguinidad genómica y detectar huellas de selección, se usó información de corridas de homocigosidad (ROH). El análisis de mezclas se realizó con el software Admixture, y los de CP, ROH y consanguinidad se realizaron con SVS-v7.6.8. El análisis de mezclas mostró evidencia de seis componentes, todos ligados a familias de sementales Holstein con diferente país de origen. Los CP no evidenciaron estratificación de la población por hato. El coeficiente de consanguinidad promedio fue de 0.59 ± 0.53 %. En las regiones del genoma con ROH más frecuentes en la población (≥20 animales), se han reportado numerosas asociaciones, QTL y genes relacionados con producción y composición de la leche, parámetros de fertilidad, susceptibilidad a enfermedades, conformación corporal, eficiencia alimenticia y algunas características de composición de la canal. Los resultados reflejan la existencia de una amplia diversidad genética en esta población y la posibilidad de realizar trabajos de mejoramiento genético a través de selección sin afectar los niveles de consanguinidad.

Abstract: In the context of economic development, the acquisition of skills plays a vital role, and training is the main tool for promoting the development of individual competencies. However, access to this training can be limited by several factors. This article focuses on identifying the determinants that influence women's participation in training programs in Chile, considering the particularities of the Chilean labor market in recent years. To achieve this objective, an analysis of the structure of the Chilean labor market is carried out using data extracted from the Labor Survey (ENCLA) corresponding to the year 2019. In addition, an analysis of the most recent data related to training, provided by the National Socioeconomic Characterization Survey (CASEN) corresponding to the years 2015 and 2017, is developed. The analysis is based on a logistic regression methodology. The results obtained show that the probability of a woman participating in training programs in Chile is mainly influenced by income level, employment particularities, educational level and family environment characteristics.

Resumen: En el contexto del desarrollo económico, la adquisición de habilidades desempeña una función de vital importancia, y la formación se erige como la herramienta principal para fomentar el desarrollo de competencias individuales. No obstante, el acceso a esta formación puede encontrarse limitado por una serie de factores. Este artículo se centra en la identificación de los determinantes que influyen en la participación de las mujeres en programas de capacitación en Chile, teniendo en cuenta las particularidades del mercado laboral chileno en los últimos años. Para alcanzar este objetivo, se realiza un análisis de la estructura del mercado laboral chileno utilizando datos extraídos de la Encuesta Laboral (ENCLA) correspondiente al año 2019. Además, se desarrolla un análisis de los datos más recientes relacionados con la capacitación, proporcionados por la Encuesta de Caracterización Socioeconómica Nacional (CASEN) correspondiente a los años 2015 y 2017. El análisis se fundamenta en una metodología de regresión logística. Los resultados obtenidos muestran que la probabilidad de que una mujer participe en programas de capacitación en Chile está principalmente influenciada por el nivel de ingresos, las particularidades del empleo, el nivel educativo y las características del entorno familiar.

Abstract After the subjugation operated by the military campaigns of 1878-1885, the native population of northern Patagonia (Mapuche-tehuelche) suffered forced relocation, the breakdown of socio-political and family units, the erasure of the identity of hundreds of minors and the declamation of the extinction of the indigenous cultural and social world. From this genocidal process, the agency of indigenous individuals and collectives was conditioned within the framework of the construction of a new society that was defined as “without Indians”. From then on, this became a condition for their possibilities of accessing land, as well as a principle of stigmatization and social differentiation. This paper focuses in addressing a particular instance of the agency of this population: the National Aboriginal Association. This organization stood out for its self-recognition as aboriginal and for its supra-community, trans-territorial and national structure. The ANA was active in a key period defining a political strategy that defended the indigenous producer, encouraged processes of communalization and articulation of the agency of the original peoples with other political actors, both in northern Patagonia and in the national context.

Resumo Após a subjugação das campanhas militares de 1878-1885, a população original (Mapuche-Tehuelche) da Patagónia setentrional sofreu deslocações forçadas, a desestruturação das unidades sociopolíticas e familiares, o apagamento da identidade de centenas de menores e a declamação da extinção do mundo cultural e social indígena. Como resultado desse processo genocida, a agência dos indivíduos e coletivos indígenas foi condicionada no âmbito da construção de uma nova sociedade que se definia como "sem índios". A partir de então, este fato tornou-se um fator determinante nas suas possibilidades de acesso à terra, bem como um princípio de estigmatização e de diferenciação social. Este artigo analisa um caso particular de agência aborígene: a Asociación Nacional de Aborígenes (Associação Nacional de Aborígenes). Esta organização destacou-se pelo seu auto-reconhecimento como indígena e pela sua estrutura supracomunitária, transterritorial e nacional. A Associação esteve ativa num período chave durante o qual definiu uma estratégia política que defendeu o produtor indígena, encorajou processos de comunalização e a articulação da agência dos povos indígenas com outros actores políticos, tanto no norte da Patagónia como no contexto nacional.

Resumen Desde el sometimiento de las campañas militares de 1878-1885, la población originaria (mapuche-tehuelche) del norte de la Patagonia sufrió la reubicación forzosa, la desestructuración de las unidades sociopolíticas y familiares, el borramiento de la identidad de cientos de menores y la declamación de la extinción del mundo cultural y social indígena. A partir de este proceso genocida, la agencia de individuos y colectivos indígenas fue condicionada en el marco de la construcción de una nueva sociedad que se definía “sin indios”. En adelante, esto se constituyó en un condicionante de sus posibilidades de acceder a la tierra, como así también en un principio de estigmatización y diferenciación social. En este artículo se aborda una instancia particular de la agencia de esta población: la Asociación Nacional de Aborígenes. Esta organización se destacó por su autoreconocimiento como aborigen y por su estructura supracomunitaria, transterritorial y nacional. La Asociación militó en un período clave durante el cual definió una estrategia política que defendía al productor indígena, alentó procesos de comunalización y de articulación de la agencia de los pueblos originarios con otros actores políticos, tanto en el norte de la Patagonia como en el contexto nacional.

ABSTRACT Introduction: Social distancing measures due to the COVID-19 pandemic prevented many children with neurodevelopmental disorders from accessing face-to-face treatments. Tele-rehabilitation grew at this time as an alternative therapeutic tool. In this study we analyzed remote cognitive rehabilitation in neurodevelopmental disorders. Methods: This was a prospective, quasi-experimental (before-after) study that included 22 patients (mean age 9.41 years) with neurodevelopmental disorders who had telerehabilitation for over six months. Results: After six months of telerehabilitation, a statistically significant improvement was found with a large effect size in these areas: attention (sustained, selective and divided), executive functions (verbal and visual working memory, categorization, processing speed), visuospatial skills (spatial orientation, perceptual integration, perception, simultanagnosia) and language (comprehensive and expressive). On the Weiss Functional Impairment Scale, all areas (family, learning and school, self-concept, activities of daily living, risk activities) improved with statistical significance. We found a positive correlation between the number of sessions and the improvement observed in executive functions (visual working memory, processing speed), attention (sustained attention, divided attention) and visuospatial skills (spatial orientation, perceptual integration, perception, simultanagnosia). We did not find statistical significance between the family structure and the number of sessions carried out. A high degree of perception of improvement and satisfaction was observed in the parents. Conclusions: Telerehabilitation is a safe alternative tool which, although it does not replace face-to-face therapy, can achieve significant cognitive and functional improvements in children with neurodevelopmental disorders.

RESUMEN Introducción: Las medidas de distanciamiento social debidas a la pandemia por COVID-19 impidieron que muchos chicos con trastornos del neurodesarrollo pudieran acceder a tratamientos presenciales. La telerrehabilitación creció en este tiempo como una herramienta terapéutica alternativa. El objetivo es analizar la telerrehXbilitación cognitiva en trastornos del neurodesarrollo. Métodos: En este estudio prospectivo, cuasi-experimental (antes-después), se incluyó a 22 pacientes (media de edad, 9,41 arios) con trastornos del neurodesarrollo que realizaron telerrehabilitación con el programa Rehametrics por más de 6 meses. Resultados: Luego de 6 meses de telerrahabilitación, se constató una mejoría estadísticamente significativa con un gran tamaño del efecto en áreas de: atención (sostenida, selectiva y dividida), funciones ejecutivas (memoria de trabajo verbal y visual, categorización, velocidad de procesamiento), habilidades visuoespaciales (orientación espacial, integración perceptiva, percepción, simultagnosia) y lenguaje (comprensivo y expresivo). En la Escala de Impedimento Funcional de Weiss mejoraron con significancia estadística todas las áreas (familia, aprendizaje y escuela, autoconcepto, actividades de la vida diaria, actividades de riesgo). Se constata una correlación positiva entre la cantidad de sesiones y la mejoría observada en funciones ejecutivas (memoria de trabajo visual, velocidad de procesamiento), atencionales (atención sostenida, atención dividida) y habilidades visuoespaciales (orientación espacial, integración perceptiva, percepción, simultagnosia). No encontramos significancia estadística entre la estructura familiar y la cantidad de sesiones realizadas. Se observó un alto grado de percepción de mejora y satisfacción en los padres. Conclusiones: La telerrehabilitación puede ser una herramienta alternativa segura que, sin reemplazar la presencialidad, puede lograr mejoras cognitivas y funcionales significativas en niños con trastornos del neurodesarrollo.
