Published: August 2024

RESUMO O aparecimento precoce de problemas na estrutura dos pavimentos e o não cumprimento do horizonte de projeto não só provocam desconforto aos usuários devido às más condições de rolamento e a falta de segurança durante o tráfego, como também demandam uma maior quantidade de matéria-prima e capital para restauração, recuperação ou reconstrução das estruturas danificadas. Os métodos de dimensionamento de pavimentos flexíveis empíricos-mecanísticos, como o novo método brasileiro de dimensionamento (MeDiNa), consideram o comportamento mecânico das camadas e do pavimento como um todo e representam de maneira mais apropriada a relação existente entre as cargas solicitantes do tráfego e a resposta apresentada pelo pavimento. O MeDiNa faz uso dos parâmetros de rigidez, como o módulo de resiliência (MR), para realizar uma análise elástico-plástica da estrutura. Este parâmetro, por sua vez, sofre algumas limitações de uso, visto que é obtido em laboratório por meio de ensaios triaxiais dinâmicos que exigem a utilização de equipamentos complexos, mão de obra especializada, além de demandar uma quantidade significativa de material e apresentar uma difícil implementação em situações práticas, tornando a execução do ensaio restrita fora das universidades e instituições acadêmicas. Tendo em vista esta problemática, este artigo propõe um modelo neural de regressão para previsão do módulo de resiliência obtido através dos parâmetros geotécnicos básicos e usuais. Ademais, para comprovar a viabilidade do modelo gerado, foram realizadas simulações considerando os diversos tipos de vias, bem como os modelos constitutivos elásticos do solo linear e não-linear. Demonstrando, assim, que se trata de um modelo satisfatório para previsão do módulo de resiliência, que poderá ser empregado tanto em rodovias com volumes de tráfego moderado quanto emvolumes elevados, quando não for possível a realização do ensaio.

Abstract Natural products, specifically plant extracts with biological activity and the ability to act as botanical biopesticides are often mistakenly considered nontoxic. Scientific evidence indicates the contrary, and for this reason, the objective of this work was to evaluate the toxicity of extracts obtained from Petiveria alliacea L. (Caryophyllales, Phytolaccaceae) using Daphnia magna Straus (Cladocera, Daphniidae) as a bioindicator to identify the plant extracts and the respective concentrations that present the highest toxicity. Leaves of P. alliacea were collected in the Peruvian amazone. From this material, three types of extract (hexane, ethanolic and aqueous) were prepared, which were used in the bioassays with D. magna to find the least toxic extract. Acute toxicity bioassays with D. magna during 48 h of exposure to hexane, ethanolic, and aqueous extracts yielded median lethal concentration (LC50) values of 26.9, 230.6, and 657.9 mg L-1, respectively. The aqueous extract presented the lowest toxicity, causing minimal D. magna mortality in the range of 6.67 to 13.33% at concentrations of 10 and 100 mg L-1. This result enables the efficient use of this plant species in a sustainable manner with a minimal environmental impact for the future development of natural products for pest control.

Abstract Population growth combined with the need for electrical energy resulted in the construction of hundreds of hydroelectric plants in the state of São Paulo, Brazil. The consequence of these interventions was the fragmentation of rivers, forming barriers, that hinder the mobility of migratory fish species, generating an impact on the life cycle of these species, especially about movement between breeding and feeding areas. For this reason, this article aimed to evaluate the state-of-the-art knowledge regarding dams, free stretches, and migratory species in the three main river basins of the state of São Paulo and its tributaries. Through a systematic review from 2003 to 2023, 89 articles were obtained, 48 of which were about dams, 5 which addressed fish transposition systems, and 36 portraying migratory species. In the first half, research focused more on the impacts of dams on fish fauna, while in the second half of the period studied, studies of migratory fish were dominant. Most research was conducted in the main rivers, with few in the tributaries. Finally, 16 migratory species, considered long-distance, were studied, the most studied being P. lineatus, P. maculatus, L. friderici, M. obtusidens and S. hilarri and the ones that occurred most frequently in rivers are Prochilodus lineatus, Pimelodus maculatus, Megaleporinus obtusidens and Salminus hilarii. Therefore, we recommend maintaining the natural flow regime that still exists in the main rivers and tributaries of the state of São Paulo, to maintain healthy populations of the inventoried species.

Published: August 2024

Abstract The sustainability of organic production and the agroecological transition of farmers in the Chapada dos Veadeiros region was evaluated using the Environmental Impact Assessment System of Agricultural Technological Innovations (AMBITEC-AGRO). The evaluation process consisted of three stages: 1st survey and data collection, 2nd application of questionnaires and 3rd individual interviews. Data were entered into electronic spreadsheets, generating quantitative results of the impacts of activities carried out on rural properties. The indicators of the data obtained are organized in weighting matrices and automatically transformed into impact indices expressed graphically. These indexes resulted in the Percentage of Impact of Technologies - PIT, which characterizes the percentage gain of technology for each of the criteria of the environmental, economic and social dimensions of the productive units. For the environmental dimension, the PIT showed a reduction of -3.73%, where the general index of impact of the activity was 0.95 and after the transition to organic and/or agroecological production it went to 1.29, with a difference of 0.34. In the economic dimension, the PIT was 7.70%, the employment variable with 0.73 and income with 3.89 were the ones that most contributed to this percentage. In the social dimension, the PIT was 7.19%, the most prominent criteria being the consumer with an average of 3.74 and health with an average of 2.99. In this sense, the transition to organic and/or agroecological management, mainly due to the reduction of environmental impacts, provided greater sustainability for agricultural activities in the region.

ABSTRACT The drying process is paramount for maintaining seed quality, where the temperature during this process directly influences germination and vigor, especially for vegetable species harvested with high moisture content. This research aimed to determine and model the drying curves of S. aethiopicum (cultivar Tinguá-verde-claro) seeds at temperatures of 35, 38, 41, and 44 ºC, as well as to evaluate the physiological quality of the seeds after drying. A completely randomized design was used, with four drying temperatures (35, 38, 41, and 44 ºC) and four replicates. Nine mathematical models were fitted using the non-linear regression analysis by the Gauss-Newton method, and the goodness of fit was assessed based on the magnitude of the coefficient of determination (R2), chi-square test (χ2), relative mean error (P), and estimated mean error (SE). Seed quality was evaluated by germination test (G), electrical conductivity (EC), and accelerated aging (AA). The Modified Midilli model best represents the drying curves of S. aethiopicum seeds at the studied temperatures. Seeds with higher germination and vigor, meaning lower electrical conductivity values and higher germination rates after accelerated aging, are achieved through drying at 35 and 38 ºC.

ABSTRACT The contribution of plant residues throughout the sugarcane cycles favors the increase of organic matter and the activity of microorganisms in the soil, especially in the surface layers. Soil texture also has an important effect on ecological processes and soil quality. In this context, the objective of this study was to evaluate soil biological attributes in different sugarcane cultivation cycles under mechanized harvesting in an Oxisol in the Savanna region of Central Brazil. The study was conducted in commercial areas under sugarcane cultivation during the 2018/2019 season, which were considered homogeneous in terms of soil and climatic conditions, with the source of variation among the areas being the cultivation cycles (C1: one cultivation cycle; C3: three cultivation cycles; C7: seven cultivation cycles) and a savanna vegetation area selected as a reference. Microbiological variables were determined in two layers, 0-0.1 and 0.1-0.2 m. The variables related to microbial biomass and texture were subjected to principal component analysis. Areas with longer sugarcane cultivation cycles show higher proportion of microbial biomass carbon in the total organic carbon in subsurface layers (microbial quotient). The performance of the soil microbial community, as expressed by total organic carbon and microbial biomass nitrogen indicators, was associated with higher presence of clay and silt, i.e., soil particles smaller than 0.02 mm.

Authors: Hossoda Dário Hachisu , Tercini João Rafael Bergamaschi , Garcia Joaquin Ignacio Bonnecarrère
Published: August 2024

ABSTRACT This study introduces an integrated model for water resources planning and management that accounts for both the quantity and quality of water in watersheds and reservoirs. Therefore, it provides a comprehensive approach for better understanding and assessing water systems. The model facilitates analyses of the spatial and temporal dynamics of hydrological processes, pollutant transport, and the behavior of rivers and reservoirs. The study evaluated pollutant load transport in the Upper Paranapanema Basin by applying the Soil Moisture Accounting Procedure (SMAP) model, Muskingum method, Streeter-Phelps buildup/washoff model, and zero-dimensional (0D) models to estimate inflows to the Jurumirim reservoir. A Python-based public library was developed to model all hydrological processes. The model calibration yielded a NSE, KGE, PBIAS and RMSE result of 0.746, 0.778, 6.5% and 73.3 m 3 s − 1, respectively. Indicating a robust simulation that attests to the versatility and reliability of the proposed approach. The methodology outlined in this research enables comprehensive water quality simulation at basin scale, thereby serving as a tool for understanding water quantity and quality dynamics and support decision-making regarding water resource planning and management.

Resumo O estudo objetivou compreender as expectativas das famílias frente às necessidades de cuidado de crianças elegíveis para cuidados paliativos (CP). Trata-se de uma pesquisa qualitativa de estudo de casos múltiplos, realizadas em duas etapas: 1) identificação das crianças elegíveis para cuidados paliativos; e 2) estudo de unidades caso, através da entrevista semiestruturada com 18 familiares diretamente ligados ao acompanhamento das crianças. Utilizou-se a análise temática em Bardin, da qual emergiram três categorias: 1) à espera de um milagre; 2) entre a aceitação e o milagre; e 3) aceitando e buscando estratégias para o cuidado. Observaram-se vivências de negação e a aceitação da doença, com impactos nas expectativas em relação aos desfechos. A religião surgiu como elemento essencial para o enfrentamento e busca por sentido da experiência vivida. A aceitação da doença em alguns casos incentivava a busca por estratégias para cuidado, sem exclusão de esperanças. Surgiram expressões não explícitas de luto e sem indícios de abordagem pela equipe. Conclui-se que existe uma necessidade de acolhimento, escuta qualificada, orientação e apoio das equipes de saúde relativos a esperanças e necessidades dos familiares de crianças elegíveis para CP, pois as expectativas dos familiares repercutem diretamente nas possibilidades de enfrentamentos menos traumáticos.

Published: August 2024

Resumo Objetivou-se refletir sobre o impacto do racismo estrutural na saúde dos adolescentes afrodescendentes brasileiros, considerando o contexto político e social do período pós-abolição, quando foi iniciada uma nova configuração de exploração e manutenção das desigualdades sociais relacionadas aos escravizados libertos e seus descendentes. É na adolescência, fase da vida ligada ao contexto social e cultural, e não apenas determinada pelo período cronológico da vida, quando geralmente o indivíduo negro começa a vivenciar de modo mais consciente o estigma da raça. Este ensaio, inicialmente, apresenta o percurso histórico da construção social da raça nos padrões de dominação e o racismo. Em seguida, reflete, balizado no racismo estrutural, sobre o papel do capitalismo monopolista no desenvolvimento e crescimento econômico do Brasil pós-abolicionista, como um dos principais mecanismos de recrutamento e manutenção da população negra nas classes sociais inferiores e marginalizadas. Por fim, discute como o racismo impacta a saúde dos adolescentes afrodescendentes brasileiros a partir da teoria ecossocial, proposta por Nancy Krieger, e de bibliografia representativa. O racismo estrutural em nossa sociedade impacta na saúde dos adolescentes negros, com forte determinação no processo de saúde-doença. Por isso, é preciso combater as disparidades históricas, no sentido de se construir uma sociedade mais democrática e igualitária.
Violência sexual contra mulheres e os processos de trabalho em unidades de saúde especializadas: avanços, desafios e resistências feministas

Published: August 2024

Resumo Neste artigo, buscou-se refletir sobre a atenção ofertada às mulheres em situação de violência sexual (VS) em duas unidades de saúde especializadas (UE) do Sistema Único de Saúde (SUS). A partir da análise qualitativa de entrevistas com profissionais dessas UE e de observações participantes realizadas entre novembro/2021 e agosto/2022, notaram-se problemas como: dificuldades em abordar o tema da VS e do aborto; despreparo para acolher mulheres em situação de VS; e fragilidades na atuação em rede. Como avanços, destacam-se: a compreensão da VS como problema social e de saúde por profissionais das equipes multidisciplinares, que se configuram como referências positivas para organização do trabalho em torno da VS nas UE; a disponibilidade de insumos necessários; e a percepção da melhoria na humanização da atenção à VS, desde a implementação da coleta de vestígios no SUS. É evidente que, para além das questões técnicas, o atendimento à VS é permeado por questões socioculturais e de gênero que atravessam os processos de trabalho, afetando a organização e a forma como o cuidado será ofertado. Enfatiza-se a importância da resistência feminista dos profissionais das equipes multidisciplinares para realização do trabalho e a urgência da formação de profissionais sensíveis para tratar das violências de gênero.

Published: August 2024

Abstract The objective of this work was to evaluate the effect of row spacing for sowing of ‘BRS Mandarim’ pigeon pea (Cajanus cajan) on soil fertility and on the yield and nutritional values of brachiaria (Urochloa decumbens) pasture. Pigeon pea was sown in an area in the initial stage of degradation and cultivated with brachiaria. Four row-spacing treatments were evaluated for pigeon pea sowing, using the following row spacing: single rows spaced at 40, 80, and 120 cm; and a double-row with 40 cm between rows, spaced at 120 cm. In addition, a reference area treatment without pigeon pea was used. The nutritive parameters of the total available forage and of the pigeon pea plants were measured at three following development stages of pigeon pea plants: vegetative stage, at 79 days after sowing (DAS); beginning of the reproductive stage, with green pods, at 157 DAS; and final stage of grain production (dry pods), at 281 DAS. The use of the legume provided an economy of up to R$ 1,716.30 ha−1 in the application of nitrogen fertilizers. Pigeon pea used as green manure provides a significant increase of 53.5 to 140% in the dry matter yield of brachiaria.

Resumen Los videojuegos son uno de los medios de entretenimiento más populares entre las personas y tienen el potencial de ser un recurso a tener en cuenta en los procesos de enseñanza-aprendizaje dado su carácter motivador e inmersivo. En esta investigación se aborda la evaluación del videojuego clásico los como recurso didáctico por parte de futuros docentes de la etapa de Educación Infantil. Para ello, participaron 261 estudiantes de grado de Educación Infantil de la Universidad de Córdoba (España). La recopilación de información se llevó a cabo mediante un cuestionario, que fue creado ad hoc y conformado por una escala Likert (1-5) con 16 ítems organizados en tres dimensiones: Perfil del estudiante/jugador; calidad del videojuego; y valoración del videojuego como recurso didáctico. Los datos recogidos se sometieron a análisis descriptivos, comparativas de medias, y a un estudio de correlaciones y regresiones lineales. Los resultados alcanzados muestran que los futuros docentes de la etapa de Educación Infantil presentan un perfil bajo como jugadores de videojuegos, adoptando una posición neutral en cuanto a la valoración de la calidad de este videojuego y su uso como recurso didáctico. En definitiva, pese a esta indiferencia hacia la utilización de este videojuego para fomentar el aprendizaje del alumnado de la etapa de Educación Infantil, no ha habido rechazo hacia este, por lo que es posible emplearlo para trabajar los contenidos de esta etapa educativa.

Over this period, 15 fish species were recorded listed in the Red Data Book of Ukraine (2009). Two of them (13.3%) were recorded in the considered water areas for the first time and are obligatory marine species. The occurrence degree of the protected fishes was established. According to the principle of occurrence and records in these water areas, they were conditionally divided into three categories:
1) permanently occurring; 2) migratory, which enter annually or almost annually; 3) rare or only once detected. The localization of these species in the considered region was determined. One of the species is considered critically threatened, and one species has vanished since 1992. The material presented is especially actual in view of consequences of the catastrophic events after the Kakhovka Dam (Hydroelectric Power Plant) destruction owing to expected drastic changes of ichthyofauna of the Dnieper estuary in the coming years.

The paper deals with seasonal changes of content and ratio of adenylate nucleotides (ATP, AMP, ADP) in tissues of perch and roach in the water bodies of Kyiv city under different degree of anthropogenic load.

The balance of the adenylates in tissues of specimens in the polluted water body shifts mainly towards increase the low-energy phosphates portion. From spring to autumn, the trend was revealed to decrease the ATP portion and increase of AMP, owing to active involvement of the high-energy phosphate into the biochemical reactions aimed at adaptation. This was confirmed by prevailing of the energy-consuming processes over energy-generating. Probably, over occurrence in the toxic environment, the roach developed effective adaptive mechanisms aimed at counteraction of the toxic load, which differed from those in perch, also confirming the species-specific reactions in taxonomically and ecologically remote species.

The changes in the adenylates' content and their ratio are considered as potential markers to assess physiological state of the fishes in the urbanized water
bodies.

The paper deals with the structural features of the waterbirds' cenoses, the fish population composition and distribution of metacercariae of trematodes, whose final hosts are waterbirds, in the model shallow lentic ecosystems of the city of Kyiv (Almazne, Martyshev, Verbne lakes and Sovski ponds).

The waterbird cenosis was dominated by ichthyophagous (58.5-75.7%) and pantophagous birds (16.4-41.42%). The black-headed gull Chroicocephalus ridibundus (21.9-56.7%) prevailed in terms of relative abundance everywhere. The ornithocenoses differed in terms of the subdominant species: in the Almazne lake it was Podiceps cristatus, in the Martyshev Lake - Sterna hirundo (14.6%), in the Sovski ponds and Verbne Lake - Anas platyrhynchos (12.8-20.2%). Differences in the coastal ornithocenoses' composition were confirmed by results of the cluster analysis WPGMA (weighted pair-group centroid (median)); distance measure - 1-Pearson r).

The coastal fish population comprised 24 species, including the native fresh-water (15 species), Ponto-Caspian and Mediterranean self-dispersers (4 species), and alien species - distant invaders (5 species).

Parasitological studies revealed trematode metacercariae localized in lens (Diplostomum sp.) and vitreous body (Tylodelphys clavata) of the eye, ripples (Apatemon gracilis), and in the integument of the body (Posthodiplostomum cuticola).

The discriminant analysis enabled to reveal significant differences in the species composition and abundance of trematode metacercariae in the water bodies with different structure of the water ornithocenoses (Wilks' Lambda: approx. 0.92235; F(8, 510) = 2.6293f) - 2.6293; the dispersion analysis showed confidently lower total number of trematode metacercariae in the Almazne Lake (Wilks' Lambda = 0.87377; F(6, 432) = 5.0253; p<0.00005).

Resumen La infección de los rumiantes domésticos con Fasciola hepática y Fasciola gigantica causa pérdidas económicas significativas estimadas en más de US $ 2000 millones por año en el sector agrícola mundial con más de 600 millones de animales infestados.  La Organización Mundial de la Salud (OMS) ha estimado recientemente que 2.4 millones de personas están infestadas con F. hepática y otros 180 millones están en riesgo de infestación. En este contexto, la pobreza ha sido identificada como uno de los principales obstáculos para un desarrollo ambientalmente seguro, ya que la mayoría de los pobres (60%) viven en áreas ecológicamente vulnerables. Son analizadas críticamente las posibles estrategias de lucha y control contra esta parasitosis en las condiciones latinoamericanas, evidenciándose entre otros aspectos, la necesidad de concientización de la comunidad sobre esta problemática, para lograr un desarrollo socio-cultural sostenible, además de otras medidas de control como son las farmacológicas, inmunológicas, físicas, químicas,  biológicas y de origen vegetal. Palabras clave: alternativas de control, desarrollo socio-cultural, impactos,   lectinas, prevalencia. Summary Infection of domestic ruminants with Fasciola hepatica and F. gigantica causes significant economic loses estimated at over US$2000 million per annum to the worldwide agricultural sector with over 600 million animals infected. The World Health Organization (WHO) has recently estimated that 2.4 million people are infected with F. hepatica, and a further 180 million are at risk of infection. In this context, poverty has been identified as one of the main obstacles for an environmentally save development, due to most of poor people (60%) live in ecologically vulnerable areas. There are critically analyzed the possible strategies of struggle and control against this pathologic entity in the Latinoamerican conditions evidencing, among other aspects, the necessity of awareness of the community on this problem in order to get a sustainable socio-cultural development among other alternatives of control such as pharmacological, inmunological, physical, chemical, biological and vegetable origin.

Published: August 2024

Resumen La ganadería, una actividad generalizada y desarrollada prácticamente en todo el país, considerada como un renglón socioeconómico de gran importancia para el desarrollo del campo y que ha sido y es cuestionada fuertemente por su desempeño productivo e impacto ambiental, debe equilibrarse en un nivel tecnológico aceptable y sostenible, que combine la productividad de los sistemas intensivos con las bondades de los extensivos. Esta monografía se realizó con el objetivo de analizar la situación de la ganadería bovina de carne en Colombia y plantear estrategias que promuevan su competitividad y sostenibilidad. La ganadería colombiana esta caracterizada por ser una actividad extensiva-extractiva, con bajos niveles de inversión y un deficiente desarrollo de acciones administrativas que la promuevan empresarialmente en un mercado globalizado, que es altamente competitivo. El silvopastoreo, los sistemas de conservación de forrajes y el uso de bloques multinutricionales, constituyen estrategias que pueden generar importantes avances en los aspectos productivo y ambiental, enmarcados en las exigencias de los mercados globalizados. Palabras clave: bloques multinutricionales, conservación de forrajes, producción bovina, sistemas ganaderos extensivos, sistemas silvopastoriles. Summary Cattle ranching a widespread activity practically in all the country, is considered as an important socioeconomic echelon of great importance for the development of rural areas. Being strongly questioned for its productivity and environmental impact, should achieve a balance between an acceptable technological level and sustainable development in order to combine the productivity of intensive systems with the benefits of the extensive systems. This work was prepared with the objective of analyzing the situation of beef cattle in Colombia and to propose strategies of clean and sustainable production that promote competitiveness. Beef cattle ranching in Colombia are characterized as an extensive and extractive activity, with low levels of investment and a low level of administrative actions to promote it in an entrepreneurial way, in a highly competitive global market. Silvopastoral systems, multinutricional blocks and forage conservation constitute strategies that can generate important advances in productive and environmental aspects. Key words: cattle ranching, extensive livestock, forage conservation, multinutricional blocks, silvopastoral systems.

Background: A single, 200-mg iron injection for newborn pigs is a common practice in swine production. It is required to provide sufficient iron for newborn pigs while avoiding the potential risk of excessive amount of iron causing oxidative stress. Objective: To evaluate the quantity and timing of a single or second iron injection into suckling piglets on growth performance and hematocrit levels. Methods: A total of 24 piglets from 4 litters were used in each experiment (3). Treatments were: Experiment 1- 1) Control: 150 mg iron injection at d 1-3 of age, 2) Iron14: additional 100 mg iron injection at 14 d before weaning, and 3) Iron7: additional 100 mg iron injection at 7 d before weaning; Experiment 2- 1) Control: 100 mg iron injection at d 1-3 of age, 2) Iron100/100: 100 mg iron at d 1-3 of age and 9 d after the first injection, and 3) Iron200: 200 mg iron injection at d 1-3 of age; and Experiment 3 (at d 3-4 of age)- 1) Fe100: 100 mg iron injection, 2) Fe200: 200 mg iron injection, and 3) BW200: 125 mg iron injection/kg body weight. Pigs were weaned at d 25-28 of age. Growth performance and hematocrit levels were measured until d 13-14 postweaning. Results: In Experiment 1, the Iron14 treatment had a greater final body weight than the control treatment (p=0.07). Hematocrit levels were greater in the Iron14 (p=0.10) and Iron7 (p<0.05) treatments than in the control treatment at d 14 postweaning. In Experiment 2, average daily gain in the postweaning period was greater in the Iron100/100 treatment than in the control (p<0.05) and Iron200 (p=0.08) treatments. Hematocrit levels in the Iron200 treatment were greater than those in the control treatment (p<0.05) at d 13 postweaning. In Experiment 3, there was no difference in growth performance, but the BW200 treatment increased hematocrit levels to a greater degree than the Fe200 treatment (p<0.10). Conclusion: An additional iron injection earlier and a split iron injection to newborn pigs could benefit postweaning growth, but not by body weight-based iron injection. Hematocrit levels increase with a greater dose of iron injected although the magnitude varies depending on injection strategies.
US Economic Growth Potentia
Authors: Davydov Andrey
Published: August 2024

This article covers the current problems of US economic growth. The policy instruments that President Biden administration uses in pursuit of the strategic objectives of influencing US economic growth are being discussed. Joseph Biden administration macroeconomic priorities are reflected in the 2023 Economic Report of the President, which calls for stimulating economic growth. The article shows that economic growth is constrained when the size of the economy reaches what economists call “potential gross domestic product (GDP)” or “capacity.” An economy’s long-run capacity depends on such factors as a growing and skilled labor force, high-quality physical infrastructure, and the efficiency of the production process.  Current situation on labor market and capital market is being discussed. Actions that affect these markets can either constrain or enhance the capacity of the economy over time. Investing in increased economic capacity enables the economy to accommodate more demand in the medium to long run, which can make it more resilient to economic shocks and minimize the risk of inflationary episodes. The core of the Biden-Harris Administration’s economic agenda is building a foundation for steady, sustainable, and shared growth by increasing economic capacity. To expand the potential growth of the U.S. economy, policymakers need to adjust how the Nation invests in response to negative changes. In some areas changing economic and social context calls for a new approach to increasing the capacity for economic growth. This article discusses how the relevant context in these areas has changed, analyzes pressing current challenges to sustained economic growth, and highlights potential strategies to confront these challenges.
