Palygoskite pellets were synthesized with lignin and WAX® and subjected to technological characterization for application in the remediation of Pb ions contained in aqueous effluents. X-ray diffraction (XRD) characterization of the palygorskite:lignin:WAX® material in a proportion of 70:15:15 revealed that the heat treatment of the pellets did not compromise the crystalline structure of the palygoskite. Texture analyses demonstrated that the surface area increased after synthesis and heat treatment, thus increasing the adsorption capacity. Regarding porosity, X-ray microtomography revealed that the pellets exhibit an irregular and porous spherical morphology with interconnected pores. Adsorption tests showed a removal of 73% of PbII contained in aqueous effluents after 15 min, with equilibrium reached in 60 min (88.36%). After the adsorption process, the presence of lead in the material was qualitatively confirmed through scanning electron microscopy and energy-dispersive X-ray spectroscopy (SEM-EDS) images. The produced pellets exhibit promising adsorbent qualities, such as strength and effective PbII ion adsorption.

Abstract Rural roads serve as pivotal conduits for the transportation of harvested crops to distribution hubs in Guarapuava-PR, a national agricultural focal point. This study evaluated the impact of incorporating brick kilns ashes(BKA) into the lateritic soil of an unpaved roadway. Mixtures of soil and BKA with three distinct granulometries were formulated, featuring substitution rates of 25%, 50%, and 75% ash relative to the total mixture mass,characterized in terms of: particle size distribution, liquid limit (LL), plastic limit (PL), and the optimum point on the compaction curve under modified energy conditions (optimal moisture content and maximum dry bulk density). Results revealed that BKA inclusion led to increases in LL, PL, OMC, CBR, alongside a reduction of MDD and expansion for the majority of mixtures, particularly within granulometry C1 at a 25% content. Finer ashes exhibited prominence in ISC and expansion outcomes. Substitutions of 75% BKA detrimentally affected geotechnical properties; however, granulometric stabilization with BKA proved feasible, particularly in soil-C2 mixtures designated for use as a sub-base. These mixtures met recommended LL and PL parameters, providing effective waste mitigation and presenting an alternative for soil improvement in pavement applications.

Resumo Estradas vicinais são muito utilizadas para o escoamento da safra da área da colheita até os centros de distribuição na cidade de Guarapuava-PR, referência nacional no setor agrícola. Esta pesquisa avaliou o efeito da adição de cinzas de fornos de olarias (CFO) ao solo laterítico de uma estrada não pavimentada. Foram produzidas misturas de solo e CFO de três diferentes granulometrias, nos teores de substituição de 25%, 50% e 75%, de cinza em relação à massa total da mistura, caracterizadas quanto à:granulometria, limite de liquidez (LL), limite de plasticidade (LP) e ponto ótimo da curva de compactação sob energia modificada (umidade ótima (wot) e peso específico aparente seco máximo (ρdmáx)). Os resultados obtidos mostraram que a adição da CFO foi responsável por aumentos nos parâmetros LL, LP, wot, ISC, bem como pela redução do ρdmáx e da expansão da maioria das misturas, principalmente para a granulometria C1, no teor de 25%. Cinzas mais finas destacaram-se nos resultados de ISC e expansão. Substituições de 75% de CFO prejudicaram as propriedades geotécnicas, mas a estabilização granulométrica com CFO revelou-se viável, especialmente em misturas solo-C2 para utilização como sub-base, atendendo aos parâmetros recomendados de LL e LP, proporcionando mitigação de resíduos e uma alternativa para melhoramento de solos para pavimentação.

Abstract Since 2010, there has been an approximate annual increase of 1% in CO2 emissions due to buildings. The reduction of energy consumption and consequently the mitigation of Greenhouse Gases are global goals due to the global issue of climate change. A key step in achieving these goals is to improve the energy performance of buildings, thereby reducing energy consumption and emissions generated by the built environment. In this regard, the present research focuses on identifying and estimating strategies to reduce energy consumption in buildings known as Community Police Units (UPCs) located in the city of Guayaquil, which corresponds to a very hot and humid climate zone. The study consists of statistical analysis of the historical energy performance of 43 buildings sharing the same architectural design. Additionally, the selection of a representative building was made for energy use monitoring and energy simulation. The results revealed a potential saving of 16 000 kWh per year by reducing the control temperature of the air conditioning system by 1°C and adjusting the on/off schedule. This is equivalent to 1 150 USD and 5 metric tons of CO2 emissions.

Resumen: Desde el 2010 existe un incremento aproximado del 1% anual respecto a las emisiones de CO2 a causa de los edificios. La disminución del consumo energético y consecuentemente la mitigación de los Gases de Efecto Invernadero son metas a nivel mundial debido a la problemática global del cambio climático. Un paso clave para alcanzar estas metas es mejorar el desempeño energético de las edificaciones y de esta manera reducir la energía consumida y las emisiones generadas por el parque edificado. En este sentido, la presente investigación se centra en identificación y estimación de estrategias para reducir el consumo de energía de los edificios llamados Unidades de Policía Comunitaria (UPC) localizadas en la ciudad de Guayaquil, y que corresponde a una zona climática húmeda muy calurosa. El estudio está compuesto por el análisis estadístico del rendimiento energético histórico de 43 edificios, que comparten el mismo diseño arquitectónico. Además, se realizó la selección de un edificio representativo para el monitoreo del uso de energía y simulación energética. Los resultados evidenciaron un potencial de ahorro de 16 000 kWh al año, al disminuir 1°C la temperatura de control del sistema de climatización y modificando el horario de encendido y apagado. Esto es equivalente a 1 150 USD y 5 toneladas equivalentes de CO2.

Abstract Introduction: Spills of flammable liquids can lead to serious accidents, mainly in industrial plants and on roads. To prevent the spread of spills, various forms of collection are used, such as absorption with porous solids. Agroindustrial waste can be used as sorbent materials for flammable liquids. Objective: To determine the sorption capacity of the residual empty-fruit bunch of oil-palm (Elaeis guineensis) and the macaw palm (Acrocomia sp.) nutshell for four organic flammable liquids. Methods: The residual biomasses of E. guineensis and Acrocomia sp. were assessed as sorbents for spilled fuels (diesel, jet fuel, commercial kerosene, and gasoline). Volumetric measurement of liquid-fuel absorption at 24 ºC was taken during a week. Desorption was measured at 50 ºC as the drying kinetics, by using moisture scales. Results: The sorption capacity of the Acrocomia sp. material was not satisfactory, compared to the E. guineensis residual material, due to differences in the residual architecture of the organic material. This last can absorb 2.4 ± 0.2 cm3 g-1 at 24 ºC, during a one-week period. Diatomite absorbs greater quantities of the organic liquids but, the fluids diffusion at 50 ºC is 0.26 ± 0.09 times more slowly in the mineral matrix, because of the greater pore tortuosity in this mineral matrix. Conclusions: The oil-palm empty fruit bunch of E. guineensis, showed lesser but adequate performance than the sorbing behavior for fire hazard mitigation of diatomite. The nutshell of macaw palm (Acrocomia sp.) did not prove to be useful for this recovery operation.

Resumen Introducción: Los vertidos de líquidos inflamables pueden producir accidentes graves, principalmente en plantas industriales y en carretera. Para prevenir la dispersión de derrames, se utilizan diversas formas de recolecta, como la absorción con sólidos porosos. Residuos agroindustriales pueden ser aprovechados como materiales sorbentes de líquidos inflamables. Objetivo: Determinar la capacidad de absorción de las biomasas residuales del pedúnculo de la palma aceitera (Elaeis guineensis) y del endocarpio del fruto de coyol (Acrocomia sp.) para cuatro líquidos orgánicos inflamables. Métodos: Las biomasas residuales de E. guineensis y de Acrocomia sp. se evaluaron como sorbentes para combustibles derramados (diésel, queroseno de aviación, queroseno comercial y gasolina). Se midió la cantidad de líquido absorbida por las biomasas a 24 ºC durante una semana, y su cinética de desorción a 50 ºC, usando balanzas de secado. Resultados: La propiedad sorbente del material de Acrocomia sp. no fue satisfactoria, comparada con el pedúnculo de E. guineensis, debido a diferencias en arquitectura residual del material orgánico. Esta última biomasa muestra una capacidad de absorción para los combustibles de 2.4 ± 0.2 cm3 g-1 a 24 ºC. La diatomita absorbe mayor cantidad de los combustibles estudiados, pero la difusión de estos fluidos a 50 ºC por la matriz mineral es solo 0.26 ± 0.09 veces lo observado para el material de E. guineensis, como resultado del mayor grado de tortuosidad de los poros de la diatomita. Conclusiones: El pedúnculo de palma aceitera (E. guineensis) mostró un adecuado potencial desempeño para la aplicación pasiva en la mitigación de los riesgos de incendio, con respecto a la diatomita. El endocarpio del fruto de Acrocomia sp. no resultó útil para esta operación de recuperación.

Abstract Introduction: Mining is one of the main drivers of deforestation of tropical forests. This activity affects the storage of aboveground biomass of these ecosystems; therefore, their ability to contribute to the mitigation of global climate change. Objective: To assess the influence of soil properties on the aboveground biomass storage of post-mining forests in the Colombian Pacific. Methods: Plots were established in areas post-mining and with different successional ages (12-15 years, 30-35 years, and mature forest). The aboveground biomass and physicochemical parameters of the soil were measured. Results: An aboveground biomass of 15.58 t ha-1, 35.17 t ha-1, and 178.32 t ha-1 was recorded at 12-15 years, 30-35 years, and mature forests, respectively. The species with the highest biomass content in post-mining forests were Cespedesia spathulata and Clidemia septuplinervia. The aboveground biomass was positively correlated with organic matter (OM), calcium (Ca), magnesium (Mg), CICE, total nitrogen (N), and silt. In contrast, the relationship was negative with sand, aluminum (Al), and potassium (K) content. It was evidenced that the relationship between aboveground biomass and soils differed in each successional age. When evaluating the changes of aboveground biomass and soils in the succession, it was observed that the aboveground biomass and total N increased with the recovery time. At the same time, the P and K decreased with succession. On the other hand, the contents of OM, Mg, Al, Ca, and CICE showed curvilinear tendencies since they increased in the first stages and then decreased in the advanced successional stages. Conclusions: Aboveground biomass increases with forest recovery time in the study area. This increase is influenced by the presence of two dominant species shared among the investigated ecosystems and by the soil’s N, P, and K content.

Resumen Introducción: La minería es una de las principales causas de deforestación de los bosques tropicales. Esta actividad afecta el almacenamiento de biomasa aérea de estos ecosistemas; y, por tanto, su capacidad para contribuir a la mitigación del cambio climático global. Objetivo: Evaluar la influencia de las propiedades del suelo en el almacenamiento de la biomasa aérea de bosques post-minería del Pacífico colombiano. Métodos: Se establecieron parcelas en áreas post-minería con diferentes edades de sucesión (12-15 años, 30-35 años y bosque maduro). Se midió la biomasa aérea y parámetros fisicoquímicos del suelo. Resultados: Se registró una biomasa aérea de 15.58 t ha-1, 35.17 t ha-1 y 178.32 t ha-1 en 12-15 años, 30-35 años y bosque maduro, respectivamente. Las especies con mayor contenido de biomasa en los bosques post-minería fueron Cespedesia spathulata y Clidemia septuplinervia. La biomasa aérea se correlacionó positivamente con la materia orgánica (MO), calcio (Ca), magnesio (Mg), CICE, nitrógeno total (N) y limo. Por el contrario, la relación fue negativa con el contenido de arena, aluminio (Al) y potasio (K). Se evidenció que la relación entre la biomasa aérea y los suelos difería en cada edad sucesional. Al evaluar los cambios de la biomasa aérea y los suelos en la sucesión, se observó que la biomasa aérea y el N total aumentaron con el tiempo de recuperación. Al mismo tiempo, el P y el K disminuyeron con la sucesión. Por otro lado, los contenidos de OM, Mg, Al, Ca, y CICE mostraron tendencias curvilíneas ya que aumentaron en los primeros estadios y luego disminuyeron en los estadios sucesionales avanzados. Conclusiones: la biomasa aérea aumenta con el tiempo de recuperación del bosque en el área de estudio. Este incremento está influenciado por la presencia de dos especies dominantes compartidas entre los ecosistemas investigados y por el contenido de N, P y K del suelo.

Resumen Los efectos desfavorables de las condiciones meteorológicas sobre la salud de la población cubana están aumentando en frecuencia e intensidad, debido a los impactos ya visibles del cambio climático sobre Cuba, problema que demanda realizar la evaluación de la vulnerabilidad de la población cubana ante los peligros regionales asociados a los procesos meteorológicos que influyen sobre el país. Se realiza una adaptación de la metodología utilizada en Cuba para los estudios de peligro, vulnerabilidad y riesgo, aplicada en este caso a la estimación del riesgo meteoro-trópico, a partir de establecer la línea base de la mortalidad general diaria en exceso para el período 2001-2020, como indicador de la vulnerabilidad de las poblaciones residentes en las mitades occidental y oriental de Cuba; para después estimar el peligro asociado a los procesos sinópticos de escala global y regional que influyen sobre esas mismas porciones del territorio. Se demuestra que existe una relación bien definida entre la mortalidad en exceso y los peligros analizados, lo cual permitió estimar satisfactoriamente la magnitud del riesgo meteoro-trópico diario y llegar a un modelo estadístico que facilita su pronóstico a corto plazo. Se comprueba la génesis meteoro-trópica de los días con mayor mortalidad en exceso, tanto en invierno como en verano, demostrando el relevante papel que tienen algunos procesos y condiciones meteorológicas sobre la salud de la población cubana, hecho que justifica la necesidad de su pronóstico y mitigación.

Abstract The unfavorable effects of meteorological conditions on the health of the Cuban population are increasing in frequency and intensity, due to the already visible impacts of climate change on Cuba, a problem that demands an evaluation of the vulnerability of the Cuban population to regional dangers. Associated with the meteorological processes that influence the country. An adaptation of the methodology used in Cuba for studies of danger, vulnerability and risk is carried out, applied in this case to the estimation of meteor-tropic risk, based on establishing the baseline of the general daily excess mortality for the period. 2001-2020, as an indicator of the vulnerability of the populations residing in the western and eastern halves of Cuba; to then estimate the danger associated with global and regional synoptic processes that influence those same portions of the territory. It is demonstrated that there is a well-defined relationship between excess mortality and the hazards analyzed, which allowed us to satisfactorily estimate the magnitude of the daily meteor-tropic risk and arrive at a statistical model that facilitates its short-term forecast. The meteor-tropic genesis of the days with the highest excess mortality is verified, both in winter and summer, demonstrating the relevant role that some meteorological processes and conditions have on the health of the Cuban population, a fact that justifies the need for its forecast and mitigation.

In the context of Lachin in Azerbaijan, the region's strategic position at the convergence of important trade routes, together with its rich cultural tapestry characterized by diverse traditions and customs, underlines its profound importance for historical research. Tragically, the Nagorno-Karabakh conflict has inflicted severe repercussions on Lachin, precipitating economic turbulence and widespread displacement among its population, highlighting the urgent need for comprehensive studies and mitigation efforts. But considering that before taking action it is necessary to have a deep knowledge of the social and cultural aspects, the objective of this work is to make a brief historical approach to the region of Lachin, Azerbaijan.

Resumo Introdução: As doenças respiratórias são uma das principais causas de doença e morte, ocupando o terceiro lugar em Portugal. Globalmente, a Doença Pulmonar Obstrutiva Crónica (DPOC) é a terceira principal causa de morte, a seguir às doenças cardiovasculares e ao acidente vascular cerebral. Identificar indivíduos de alto risco e implementar tratamento precoce é crucial devido à variabilidade dos sintomas e exacerbações na DPOC. Este estudo teve como objetivo determinar estratégias eficazes para prevenir exacerbações e complicações relacionadas. Métodos: Foi desenvolvido um estudo Delphi que envolveu 15 especialistas de diversas áreas, incluindo médicos, enfermeiros, gestores de saúde, decisores políticos, especialistas em saúde pública e representantes de organizações de pessoas com doença. Os especialistas utilizaram uma escala, variando de “Concordo” a “Discordo”, para alcançar um nível de consenso de 73,3% para cada estratégia. Foram realizadas três rodadas para abordar seis perguntas relacionadas com o diagnóstico precoce e seguimento dos doentes. A primeira ronda centrou-se na identificação dos principais desafios enfrentados pelo sistema de saúde português na gestão da DPOC, dos obstáculos na identificação e gestão das exacerbações da DPOC e das estratégias eficazes para ultrapassar as barreiras identificadas. A segunda e a terceira rondas envolveram a análise da informação recolhida e a votação de cada indicador para obter consenso. Os indicadores resultantes foram categorizados em dois grupos: barreiras, desafios e constrangimentos na gestão da DPOC e estratégias de ação para melhorar a prevenção, a referenciação e diminuir exacerbações e o peso desta doença. Resultados: De um total de 134 indicadores válidos gerados, 108 obtiveram consenso. Dos indicadores consensualizados pelos peritos, 18 dizem respeito a barreiras, desafios e constrangimentos, enquanto 90 são referentes a estratégias de ação para a DPOC. Entre as estratégias formuladas, 25 indicadores com consenso visam estratégias de prevenção, 24 indicadores com consenso têm como alvo a referenciação da DPOC e 41 indicadores com consenso concentram-se em mitigar as exacerbações da DPOC e reduzir a carga da doença. Discussão/Conclusão: Este estudo enfatiza a necessidade de investimento integrado na saúde respiratória e o reconhecimento do impacto da DPOC na vida das pessoas, nos sistemas de saúde e na economia. A prevenção e o tratamento adequado das exacerbações são cruciais para uma gestão eficaz da DPOC e para reduzir a morbidade e a mortalidade associadas. Os especialistas destacam a importância de melhorar a coordenação entre diferentes níveis de cuidados, integrar sistemas de informação e descentralizar as responsabilidades hospitalares. A pandemia da COVID-19 reforçou a importância da saúde respiratória individual e coletiva, enfatizando a necessidade de investir na promoção da saúde e na consciencialização sobre a DPOC.

Abstract Introduction: Respiratory diseases, ranking the third in Portugal, contribute significantly to illness and mortality. Chronic obstructive pulmonary disease (COPD) is the third-leading cause of death globally. Identifying high-risk individuals and implementing early treatment is crucial due to the variability of COPD symptoms and exacerbations. This study aimed to identify effective strategies for preventing exacerbations and complications. Methods: A Delphi involving 15 experts was performed. Experts included physicians, nurses, health managers, policymakers, public health experts, and patient organizations. Consensus was achieved at 73.3% for each strategy using a scale ranging from “agree” to “disagree.” Three rounds were conducted to address six questions related to early diagnosis and patient follow-up. Challenges faced by the Portuguese Health System in managing COPD, obstacles in COPD exacerbation diagnosis and management, and effective strategies to overcome barriers were identified in the first round. The second and third rounds involved analyzing the gathered information and voting on each indicator to achieve consensus, respectively. Indicators were categorized into constraints and barriers, and strategies for reducing COPD exacerbations and disease burden. Results: Out of a total of 134 valid indicators generated, 108 achieved consensus. Among the indicators agreed upon by experts, 18 pertained to barriers, challenges, and constraints, while 90 focused on action strategies for COPD. Among the strategies formulated, 25 consensus indicators target prevention strategies, 24 consensus indicators aim to enhance COPD referrals, and 41 consensus indicators focus on mitigating COPD exacerbations and reducing the overall disease burden. Discussion/Conclusion: This study emphasizes the need for integrated investment in respiratory healthcare and recognition of the impact of COPD on patients, healthcare systems, and economies. Prevention and appropriate treatment of exacerbations are crucial for effective COPD management and reducing associated morbidity and mortality. Experts highlight the importance of improving coordination between different levels of care, integrating information systems, and decentralizing hospital responsibilities. The COVID-19 pandemic has further emphasized the importance of individual and collective respiratory health, necessitating investment in health promotion and COPD awareness.

Abstract In an increasingly dynamic and complex world, the professional figure of teachers who show commitment to their work acquires fundamental importance in quality education. In this sense, this research aims to analyze burnout syndrome as a predictor of work commitment in teachers of private universities in the city of Chiclayo, Peru, in a context of mitigation of the COVID-19 pandemic. This is an empirical study of cross-sectional predictive design. The final sample included 100 undergraduate teachers, of both sexes, whose ages ranged from 35 to 60 years (M=46.63; SD=9.90). The instruments applied were the Burnout Syndrome Scale version for teachers and the Utrecht Work Engagement Scale, virtualized in Google Forms. The data collected were subjected to simple regression analysis, also reporting effect size indices and statistical power, to ensure greater scope and precision in the results. Low levels of burnout syndrome and high levels of work engagement were reported; moreover, burnout syndrome negatively and significantly predicted work engagement and its dimensions of vigor and dedication; not so for absorption. Therefore, the reported findings suggest that burnout syndrome can predict work engagement and its factors, except for absorption, in teachers of private universities in Chiclayo. The limitations and practical implications of the study are discussed.

Resumen En un mundo cada vez más dinámico y complejo, la figura profesional docente que muestra compromiso con su quehacer adquiere fundamental importancia en una educación de calidad. En ese sentido, esta investigación tiene como objetivo analizar el síndrome del quemado como predictor del compromiso laboral en docentes de universidades privadas de la ciudad de Chiclayo, Perú, en un contexto de mitigación de la pandemia por COVID- 19. Se trata de un estudio empírico de diseño predictivo transversal. La muestra final incluyó 100 docentes de pregrado, de ambos sexos, cuyas edades oscilaban entre los 35 y 60 años (M=46.63; DE=9.90). Los instrumentos aplicados fueron la Escala de Síndrome de Burnout versión para docentes y la Escala Utrecht de Engagement Laboral, virtualizados en Google Forms. Los datos recopilados se sometieron a análisis de regresión simple, reportando también índices de tamaño de efecto y potencia estadística, para garantizar un mayor alcance y precisión en los resultados. Se reportaron niveles bajos de síndrome del quemado y altos de compromiso laboral, además, el síndrome del quemado predijo de manera negativa y significativa el compromiso laboral y sus dimensiones de vigor y dedicación; no así para absorción. Por tanto, lo reportado sugiere que el síndrome del quemado puede predecir al compromiso laboral y sus factores, salvo la absorción, en docentes de universidades privadas de Chiclayo. Se discuten las limitaciones e implicancias prácticas del estudio.

Abstract The study evaluates the generation and recovery capacity of methane at the Villavicencio Landfill in Colombia, using the LandGEM model. It shows a significant increase in methane generation, rising from about 1.5 million cubic meters in 2010 to over 8.5 million in 2020, indicating a growing urgency to implement effective mitigation measures. It was estimated that by the year 2042, the electrical energy production from methane could be 248.067 kW/day, capable of supplying about 43.705 homes monthly. Additionally, thermal energy generation would be 468.572 kWh/day, useful for industrial processes. Management scenarios were proposed, where, for example, operational optimization could increase electric production to 342.333 kW/day, benefiting more than 60.000 homes monthly. The conclusions highlight the direct correlation between the amount of waste and methane generation, and the significant potential for converting these emissions into energy, pointing towards regional energy self-sufficiency and sustainability. Methane recovery represents a valuable alternative to the dependence on fossil fuels and for the development of a circular economy.

Resumen El estudio evalúa la generación y capacidad de recuperación de metano en el Relleno Sanitario de Villavicencio, Colombia, mediante el modelo LandGEM. En donde se observa un aumento significativo en la generación de metano, pasando de alrededor de 1,5 millones de metros cúbicos en 2010 a más de 8,5 millones en 2020, lo que indica una creciente urgencia por implementar medidas de mitigación efectivas. Se estimó que, para el año 2042, la producción de energía eléctrica del metano podría ser de 248.067 kW/día, capaz de abastecer a unos 43.705 hogares mensualmente. Asimismo, se generaría energía térmica de 468.572 kWh/día, útil para procesos industriales. Se plantearon escenarios de gestión, donde, por ejemplo, la optimización operacional podría aumentar la producción eléctrica a 342.333 kW/día, beneficiando a más de 60.000 hogares mensualmente. Las conclusiones resaltan la correlación directa entre la cantidad de residuos y la generación de metano, y el significativo potencial de convertir estas emisiones en energía, apuntando hacia la autosuficiencia y sostenibilidad energética regional. El aprovechamiento del metano representa una alternativa valiosa frente a la dependencia de combustibles fósiles y para el desarrollo de una economía circular.

Abstract In this study, we have carried out a variationist analysis of the use of mitigation resources in oral narrations of personal experiences both individually and conversationally constructed by speakers from Santiago de Chile. For this purpose, we have followed the model proposed in González Riffo yand Guerrero González (2017), who have classified the mitigation resources in three pragmatic axes: ‘certainty’, ‘veracity’, and ‘esteem’. The extralinguistic factors are the informants’ sex, their socioeconomic status, and the type of narrative construction. We have contrasted 36 individual narrations and 54 conversational (or co-constructed) narrations. Results have shown that speakers from high socioeconomic status mitigate more than those in medium or low status; females mitigate more than males in individual narrations; and, in conversational narrations, females mitigate less in those constructed by two males in comparison with those constructed by two females or a male and a female. Lastly, it is possible to observe that in individual narrations speakers mitigate less than in conversational narrations, which can be explained by a ‘conversational validation’ that can be found in the latter.

Resumen En este trabajo se realiza un análisis variacionista del empleo de recursos de atenuación en narraciones orales de experiencia personal construidas individual y conversacionalmente por hablantes de Santiago de Chile. Para esto, se sigue el modelo expuesto en González Riffo y Guerrero González (2017), quienes clasifican los recursos de atenuación según tres ejes pragmáticos: ‘certeza’, ‘veracidad’ y ‘estima’. Los factores extralingüísticos corresponden al sexo de los informantes, su grupo socioeconómico y el tipo de construcción narrativa. Se contrastan 36 narraciones individuales y 54 narraciones conversacionales (o co-construidas). Los resultados muestran que los hablantes del grupo socioeconómico alto atenúan más que los de los grupos bajo y medio; las mujeres atenúan más que los hombres en narraciones individuales; y en las conversacionales aquellas construidas por dos hombres presentan menos atenuadores que las construidas por dos mujeres y un hombre y una mujer. Por último, es posible observar que en las narraciones individuales los hablantes atenúan menos que en las conversacionales, lo que se explicaría por una ‘validación conversacional’ que es apreciable en las últimas.

ABSTRACT: The National School Feeding Program (PNAE) is the oldest and most extensive food and nutrition program in Brazil. Art. 14 of Law 11.947 stipulate that at least 30% of its operational resources need be used to purchase family farming products. However, there are important barriers that hinder the application of this law. The present article developed a conceptual model that described and analyzed the barriers to this requirement. A systematic literature review identified twelve barriers, divided into three constructs political administrative infrastructure and human capital, which enables PNAE management to develop mitigation strategies, including a larger number of farmers in the program, thereby increasing its efficiency.

RESUMO: O Programa Nacional de Alimentação Escolar (PNAE) é considerado o programa de alimentação e nutrição mais antigo e de maior abrangência do Brasil. O art. 14 da Lei n. 11.947 determina que um percentual mínimo de 30% dos seus recursos operacionais deva ser empregado na compra de produtos da agricultura familiar. Contudo, existem barreiras importantes que dificultam a aplicação dessa Lei. Este artigo tem como objetivo desenvolver um modelo conceitual que permita descrever e analisar as barreiras impeditivas à esta exigência. Uma revisão sistemática da literatura permitiu identificar doze barreiras que se agrupam em três constructos: político-administrativo, infraestrutura e capital humano, que possibilita aos gestores do PNAE o desenvolvimento de estratégias de mitigação, inserindo um maior quantitativo de agricultores no programa, aumentando sua eficiência.
