Asphaltenes are complex molecules with a tendency to aggregate. This property can be an issue for the oil industry due to CO2 reinjection into reservoirs to mitigate these gas emissions. The present theoretical study aimed to study the CO2 interaction with no-substitute and substituted coronene as an asphaltene model compound at CAM-B3LYP-D3/6-311G(d,p) level. The electronic properties were evaluated using harmonic oscillator model of aromaticity (HOMA), quantum theory of atoms in molecules (QTAIM), and reduced density gradient (RDG) methods. The results showed that the coronene’s functionalization by a sulfur atom changes the coronene’s electronic structure. However, functionalization does not change the type of interactions between the monomers, as they remain predominantly van der Waals interactions. CO2 interaction with substituted coronene barely changed due to the presence of sulfur atoms. However, in dimers, the position of the heteroatom directly influences the interaction with CO2, although it is insufficient to change the interaction’s magnitude. For this reason, our results indicate that the sulfur heteroatom in asphaltenes should be addressed. However, new studies must be conducted by increasing the number of substituents, CO2 numbers, and the model size. aggregate CO emissions nosubstitute no substitute CAMB3LYPD3/6311Gd,p CAMB3LYPD36311Gdp CAMBLYPDGdp CAM B3LYP D3/6 311G d,p D3 6 d p B LYP D G CAM-B3LYP-D3/6-311G(d,p level HOMA, HOMA , (HOMA) QTAIM, QTAIM (QTAIM) RDG (RDG methods coronenes s structure However monomers dimers magnitude reason addressed substituents numbers size CAMB3LYPD3 6311Gd CAMB LYPD Gd Gdp BLYP D36 D3/ dp (HOMA (QTAIM CAMBLYPD CAMB3LYPD

Abstract The orthodox view of the effect of trade on GDP per capita assumes greater growth and equity, the heterodox theory refutes the argument and predicts inequitable and divergent results between countries. We resume the discussion using information from 1980 to 2022 in 102 countries, applying a panel data methodology and slope disaggregation. The goal is to test whether trade has adverse effects in lower-income countries and how the effect has changed over time. The results show that trade negatively affects GDP per capita growth mainly through imports, this tends to worsen over time and the impact is greater in poor countries. The main implication is the growing income divergence between nations; the recommendation is that governments and multilateral organizations continue to explore ways to balance and socialize trade. It is concluded that heterodox postulates, such as the vision of Thirlwall on trade, continue to be valid. The originality of the document lies in the disaggregation of results by countries and time blocks, as well as exports and imports.

Resumen La visión ortodoxa del efecto del comercio sobre el PIB per cápita supone mayor crecimiento y equidad, la teoría heterodoxa refuta el argumento y predice resultados inequitativos y divergentes entre países. Reanudamos la discusión utilizando información de 1980 a 2022 en 102 países, aplicando una metodología de datos panel y desagregación de pendientes. El objetivo es probar si el comercio tiene efectos adversos en países de menores ingresos y como el efecto ha cambiado en el tiempo. Los resultados muestran que el comercio afecta negativamente el crecimiento del PIB per cápita principalmente a través de las importaciones, esto tiende a empeorar con el tiempo y el impacto es mayor en países pobres. La principal implicación es la creciente divergencia de ingresos entre las naciones, la recomendación es que gobiernos y organismos multilaterales continúen buscando formas de equilibrar y socializar el comercio. Se concluye que postulados heterodoxos, como la visión de Thirlwall sobre el comercio, continúan teniendo vigencia. La originalidad del documento radica en la desagregación de resultados por países y bloques de tiempo, así como exportaciones e importaciones.

Abstract The aim of this article is to apply the model of Thirlwall's simple rule to analyze the causes of the divergent equilibrium growth rates between China and Mexico. The Fully Modified OLS method by Peter C. B. Phillips and Bruce E. Hansen is used. This approach offers precise estimates for the long-term relationships between GDP and exports, addressing endogeneity and autocorrelation. Through this estimator, we obtained the equilibrium GDP growth rates and the income elasticities of import demand. It is recommended to implement industrial and trade policies in Mexico to boost its growth. A limitation is that a more detailed analysis of differentiated growth was not conducted, so it would be necessary to explore further the extended version of Thirlwall's Law. The originality of our work lies in contributing to the understanding of the disparities in economic growth between China and Mexico. In conclusion, we demonstrate the different growth capacities based on the constraints of each country's current accounts.

Resumen El objetivo de este artículo es aplicar el modelo de la regla simple de Thirlwall para analizar las causas de las tasas divergentes de crecimiento de equilibrio entre China y México. Se utiliza el método Fully Modified OLS de Peter C. B. Phillips y Bruce E. Hansen. Este enfoque ofrece estimaciones precisas para las relaciones de largo plazo entre el PIB y las exportaciones, abordando la endogeneidad y la autocorrelación. Mediante este estimador, obtuvimos las tasas de crecimiento de equilibrio del PIB y las elasticidades ingreso de la demanda de importaciones. Se recomienda implementar políticas industriales y comerciales en México para impulsar su crecimiento. Una limitante es que no se realizó un análisis más detallado del crecimiento diferenciado, por lo que habría que explorar más adelante la versión ampliada de Ley de Thirlwall. La originalidad de nuestro trabajo consiste en que contribuye a la comprensión de las disparidades de crecimiento económico entre China y México. En conclusión, evidenciamos las distintas capacidades de crecimiento en función de las restricciones de las cuentas corrientes de cada país.

Die inflasiekoers en die produksiegaping speel 'n belangrike rol in die monetêrebeleidstand-punt. Alhoewel die publiek inflasie redelik goed verstaan, is die produksiegaping 'n relatief onbekende begrip. Definisies van potensiële produksie kan dubbelsinnig wees, aangesien die term dikwels gebruik word om verwante, maar logies afsonderlike, konsepte te beskryf. Die produksiegaping word ook nie direk waargeneem nie en word afgelei uit beramings van potensiële produksie, wat self nie waarneembaar of meetbaar is nie en dus beraam moet word. Hierdie beramings kan egter sensitief wees vir verskillende metodologiese paradigmas en databeskikbaarheid. Die doel van hierdie artikel is om by te dra tot 'n beter begrip van en groter deursigtigheid in plaaslike monetêre beleid deur die rol van die produksiegaping in Suid-Afrikaanse monetêre beleid te verduidelik. Eerstens word die idees onderliggend aan die konsep van die produksiegaping bespreek, waarna 'n werksdefinisie van die produksiegaping in die konteks van monetêre beleid voorgestel word. Verskeie metodologieë en empiriese tegnieke waarvolgens potensiële produksie en die produksiegaping beraam kan word, word bespreek, insluitende eenveranderlike statistiese tegnieke, strukturele modelle en semistrukturele benaderings. Die artikel verduidelik voorts hoe die Suid-Afrikaanse Reserwebank (SARB) die plaaslike produksiegaping beraam en hoe hierdie beraamde produksiegaping op die monetêrebeleidstand-punt inwerk. Ten slotte word die SARB se monetêrebeleidstandpunt beskou met betrekking tot die inflasiekoers en produksiegapingsberamings oor die afgelope twee dekades ten einde die reaksie van die plaaslike monetêre beleid op groot ekonomiese skokke soos die wêreldwye finansiële krisis en COVID-19 te illustreer, en ten einde die beramings se sensitiwiteit vir datahersienings uit te lig.

The inflation rate and the output gap are two of the main determinants of the monetary policy stance. However, while inflation is relatively well understood by the public, the output gap is not. The output gap is not directly observed and is derived from estimates of potential output. Potential output is also not observable or measurable, and therefore needs to be estimated. Such estimates can, however, be sensitive to different methodological paradigms and the availability of data, while definitions of potential output may be ambiguous, because the term is often used to describe related, but logically distinct, concepts. With the aim of contributing to a better understanding of and greater transparency in domestic monetary policy, this paper describes the role of the output gap in South African monetary policy by broadly examining the following three questions: (i) What exactly is the output gap?; (ii) How is it measured? and (iii) Why is it important? To begin with, the idea underlying the concept of the output gap is explained and a tentative working definition of the output gap in the context of monetary policy is provided. Various methodologies and empirical techniques of estimating potential output and the output gap are then discussed, including univariate statistical techniques, structural models and semi-structural approaches. This is followed by an explanation of how the South African Reserve Bank (SARB) estimates the domestic output gap, and how the estimated output gap feeds into the monetary policy stance. Finally, the SARB's monetary policy stance is viewed in relation to the inflation rate and output gap estimates over the last two decades to illustrate the domestic monetary policy response to notable economic events such as the global financial crisis and the COVID-19 shock, and to highlight the sensitivity of the estimates to data revision. This paper shows that both actual and potential economic growth have declined over the last decade, even without taking into account the COVID-19 shock. This is consistent with the South African empirical literature, and points to a worrying and persistent stagnation in domestic economic activity. After strong economic activity during the early 2000s, the economy started slowing down in 2008. This may be ascribed to a number of factors, including the introduction of load-shedding in 2007, changes in the global economic landscape following the globalfinancial crisis, dwindling infrastructure investment after the 2010 FIFA World Cup tournament, and uncertainty about domestic economic policy. COVID-19 brought about a massive economic shock in 2020. Lockdown regulations saw capital and labour withdrawn from economic use, which caused real GDP and potential output to contract by 6,2% and 2,7%, respectively, for the year. The output gap, which has mainly remained in negative territory since 2009, fell to -7,9% in the second quarter of 2020. In response to the crisis, the SARB drastically lowered the policy rate and applied several other financial market interventions, but even this extensive range of stimuli failed to prevent an economic collapse. Moreover, the output gap has remained negative despite a minor rebound of the economy in 2021 and 2022, which indicated that economic activity remained on its weakpre-COVID-19 trajectory. Inflation has stabilised markedly since 2010. This may be partly due to weak domestic economic activity that does not exert significant domestic inflationary pressures. In fact, many of the notable inflationary episodes of the last 25years were largely caused by external factors, such as the rand depreciation shock and the global financial crisis. This benign domestic inflationary environment has arguably made it easier for the SARB to achieve its inflation target. Such consistency has contributed to an increase in the SARB's credibility, which, in turn, has led to inflation expectations that are lower and better anchored.

Abstract Pig Respiratory and Reproductive Syndrome (PRRS) is a disease with economic repercussions for pig farmers worldwide as it causes low feed efficiency and, therefore, less weight gain in the fattening stage. The effect of dietary supplementation with docosahexaenoic acid (DHA), turmeric oleoresin and capsicum (EP, plant extracts) on the productive performance of fattening pigs and on the health of a herd affected by PRRS was evaluated. Nine-hundred and sixty fattening pigs with an initial average weight of 5.21 ± 0.065 kg was randomly assigned to one of four treatments, T1, control; T2, DHA; T3, EP; T4, DHA+EP. The variables analyzed were weight at day 70 of life (P70), weight at market (PM), daily weight gain at day 70 of life (GDP70), daily weight gain to market (GDPM), feed conversion at day 70 of life (CA70) and feed conversion at market (CAM). T2 and T4 diets exceeded the control and T3 in P70 and GDP (P < 0.05), T2 and T4 did better than the control and T3 in CA70 (P < 0.05). T2, T3, and T4 surpasssed the control in PM (P < 0.05). All pigs had antibodies against PRRS throughout the study, although pigs in the second fattening cycle showed higher IgG values for T2 and T4. The cost of production for T2, T3 and T4 was lower for GDPM, CAM and PM. In conclusion, the treatments T2, T3, and T4 were superior to the control in PM and therefore, the use of DHA and phylogens wasp cost-effective.

Resumen El Síndrome Respiratorio y Reproductivo del Cerdo (PRRS) es una enfermedad que impacta económicamente a la porcicultora, pues provoca baja eficiencia alimenticia y menor ganancia de peso en la fase de engorda. Se evaluó el efecto de adicionar la dieta con ácido docosahexaenoico (DHA), oleorresina de cúrcuma y capsicum (EP, extractos de plantas) sobre el desempeño productivo de cerdos en engorda y en la salud de una piara con PRRS. Novecientos sesenta cerdos con un peso promedio inicial de 5.21 ± 0.065 kg fueron asignados a uno de cuatro tratamientos: T1, testigo; T2, DHA; T3, EP; T4, DHA+EP. Las variables fueron: peso al día 70 (P70), peso a la salida al mercado (PM), ganancia diaria de peso al día 70 (GDP70), ganancia diaria de peso al mercado (GDPM), conversión alimenticia al día 70 (CA70) y conversión alimenticia a la salida al mercado (CAM). P70 y GDP mostraron que las dietas T2 y T4 (P < 0.05) superaron al testigo y a T3. En CA70, los cerdos de T2 y T4 fueron mejores que el testigo y T3 (P < 0.05). En PM, T2, T3 y T4 superaron al testigo (P < 0.05). Todos los cerdos fueron positivos a PRRS durante todo el estudio, aunque los cerdos del segundo ciclo de engorda mostraron más IgG en T2 y T4. El costo de producción para T2, T3 y T4 fue menor para GDPM, CAM y PM. En conclusión, las dietas experimentales fueron superiores al testigo en PM y, por ende, el uso de DHA y fitogénicos resultó rentable.

RESUMO Nos últimos 30 anos, ocorreram transformações significativas nas relações de trabalho, no sindicalismo e na própria comunicação sindical no Brasil. O avanço do neoliberalismo e das plataformas online expandiu a informalidade, fragmentou as organizações da classe trabalhadora e produziu um proletariado da era digital ainda mais precarizado. Sob os efeitos do capitalismo de plataforma, os trabalhadores de aplicativos começaram a experimentar novos arranjos de resistência a partir da convergência midiática e das possibilidades de existir e lutar em ambientes digitais. Este artigo analisa as experiências de comunicação do grupo de moto-entregadores Galera da Pressão (GDP), em atividade na cidade de Natal, no Estado do Rio Grande do Norte, desde 2020. As reflexões buscaram identificar possíveis semelhanças e diferenças com a tradicional comunicação sindical, a partir da observação de uma paralisação liderada pelo coletivo, em maio de 2022, cujas ações foram registradas no Instagram do grupo.

ABSTRACT In the last 30 years, significant transformations have occurred in labor relations, unionism, and union communication itself in Brazil. The advance of neoliberalism and online platforms has expanded informality, fragmented working class organizations, and produced an even more precarious digital age proletariat. Under the effects of platform capitalism, app-based workers began to experiment with new resistance arrangements based on media convergence and the possibilities of existing and fighting in digital environments. This article analyzes the communication experiences of the group of delivery motorcyclists Galera da Pressão (GDP), which has been operating in the city of Natal, in the state of Rio Grande do Norte, since 2020. The reflections sought to identify possible similarities and differences with the traditional union communication, based on the observation of a strike led by the collective, in May 2022, whose actions were recorded on the group's Instagram.

ABSTRACT This paper discusses some comparative analysis between the pattern of economic performances in Asia and Western Europe during 1950s-2020s through political economies perspective. The Asian and Western European economic performances are investigated through some stylized facts in the sense of economic factors. Three analyses are used to explain the general pattern of these regions. First, this study examines the pattern of GDP growth per capita during the 1950s-2020s, focusing on several countries in this region. Second, the analysis captures the pattern of linkages of economic variables in this region related to the principle of Circular and Cumulative causation (CCC) and contradiction. Third, the analysis employs a historical perspective underpinned by the results in the second analysis. This third analysis is crucial to appreciating Asia’s global economic performance and also the process of Western deterioration phenomenon through long wave, including the occurrence recession and financial crises. The institutions of globalization and neoliberalism that put the power of capital promoted a financial crisis several times during the decades of 1980s-2020. The financial crisis is depicted by contradictions in the structural linkages among economic factors in Western Europe over the period. 1950s2020s ss 1950s 2020s s regions First 1950s2020s, 2020s, Second CCC (CCC contradiction Third Asias wave crises 1980s2020. 1980s2020 1980s 2020. 2020 1980s-2020 period 1980s202 202 1980s-202 1980s20 20 1980s-20 1980s2 2 1980s-2 1980s-

RESUMO Este artigo discute algumas análises comparativas entre o padrão de desempenho econômico na Ásia e na Europa Ocidental durante os anos 1950-2020 através da perspectiva das economias políticas. Os desempenhos econômicos da Ásia e da Europa Ocidental são investigados por meio de alguns fatos estilizados no sentido de fatores econômicos. Três análises são usadas para explicar o padrão geral dessas regiões. Em primeiro lugar, este estudo examina o padrão de crescimento do PIB per capita durante os anos 1950-2020, com foco em vários países dessa região. Em segundo lugar, a análise captura o padrão de vínculos de variáveis econômicas nesta região relacionadas ao princípio da Causação Circular e Cumulativa (CCC) e contradição. Em terceiro lugar, a análise emprega uma perspectiva histórica sustentada pelos resultados da segunda análise. Esta terceira análise é crucial para apreciar o desempenho econômico global da Ásia e também o processo de deterioração do fenômeno ocidental por meio de ondas longas, incluindo a ocorrência de recessão e crises financeiras. As instituições da globalização e do neoliberalismo que colocaram o poder do capital promoveram várias vezes uma crise financeira durante as décadas de 1980-2020. A crise financeira é retratada por contradições nas ligações estruturais entre os fatores econômicos na Europa Ocidental durante o período. 19502020 1950 2020 1950-202 políticas regiões lugar 19502020, 2020, CCC (CCC contradição longas financeiras 19802020. 19802020 1980 2020. 1980-2020 período 1950202 195 202 1950-20 1980202 198 1980-202 195020 19 20 1950-2 198020 1980-20 19502 1 2 1950- 19802 1980-2 1980-

ABSTRACT The macroeconomic approach is a way of analyzing and studying issues related to the global analysis of the economy. The objective of this paper is to estimate the influence of macro- economic determinants on the achievement of the monetary poverty reduction targets in Paraguay during the period 1997-2020. It works specifically with the first two targets that have to do with the eradication of extreme poverty and the reduction to 50% of total poverty. The macroeconomic determinants analyzed are GDP, CPI, the Gini index and social spending. For this purpose, we propose the application of an econometric model which, based on regression models, allows us to calculate the incidence of each of the variables analyzed on monetary poverty. In addition, projections are made to infer whether or not the objectives of SDG 1 can be met and under what conditions. The results obtained allow us to affirm, on one hand, that all the determinants analyzed have a significant impact on monetary poverty and, on the other hand, allow us to infer that none of the targets can be met by 2030, either by maintaining constant or even increasing economic growth. This leads to the conclusion that the effectiveness of poverty reduction strategies lies in combining efforts that link GDP growth with equitable redistribution of resources and social investment.

RESUMEN Este trabajo tiene como objetivo estimar la influencia de los determinantes macroeconómicos en la consecución de las metas de reducción de pobreza monetaria en Paraguay durante el período 1997-2020. Los determinantes macroeconómicos analizados son el PIB, el IPC, el índice de Gini y el gasto social. Para el efecto, se propone la aplicación de un modelo econométrico, el cual, a partir de modelos de regresión, permite calcular la incidencia de cada una de las variables analizadas sobre la pobreza monetaria. Además, se realizan proyecciones para inferir si se pueden cumplir o no con los objetivos del ODS 1 y bajo qué condiciones. Los resultados obtenidos permiten afirmar, por un lado, que todos los determinantes analizados inciden significativamente sobre la pobreza monetaria y, por otro lado, permiten inferir que ninguna de las metas se puede cumplir al 2030, ya sea manteniendo constante o incluso aumentando el crecimiento económico. Esto permite concluir que la eficacia en las estrategias de reducción de pobreza radica en combinar esfuerzos que vinculen el aumento del PIB con la redistribución equitativa de recursos y la inversión social.

Abstract Mexico’s school enrolment in the 2021-2022 school year corresponds to 5.07 million students (5.5 % in higher technical and normal levels; 86.2 % in bachelor’s degrees; 7.2 % in specialties and master’s degrees; 1.1 % in doctorates), representing 4 % of the total national population. The article is structured on the basis of the deductive method and with a quantitative archetype; its objective is to determine the correlation between the higher education student population and economic growth and human development. It is hypothesized that higher education will contribute significantly to the achievement of these objectives, in the first instance to try to achieve economic growth, and then to gain access to economic, social, sustainable and human development. The hypothesis was confirmed that in Mexico during the period from 2010 to 2022, the highest number of higher education students can explain 82.6 % of the variations experienced in the increase of the Gross Domestic Product (GDP) or economic growth. It was considered that the highest levels of education in the country (doctorate and master’s degrees) would have a decisive influence on the increase in GDP (economic growth) and a better position in the Human Development Index (HDI), but it turned out that the most influential variable in the estimated linear regressions is enrolment at the bachelor’s degree.

Resumen La matrícula escolar de México en el ciclo escolar 2021-2022 corresponde a 5,07 millones de alumnos (5,5 % en nivel técnico superior y normal, 86,2 % en licenciatura, 7,2 % en especialidad y maestría, y 1,1 % en doctorado), representando el 4 % de la población total nacional. El artículo se estructura con base en el método deductivo y con un arquetipo cuantitativo, teniendo como objetivo conocer el estado de correlación existente entre el universo estudiantil de educación superior con el crecimiento económico y el desarrollo humano. Se parte de la hipótesis que la educación superior contribuirá significativamente al logro de estos objetivos, en primera instancia, para tratar de alcanzar el crecimiento económico, y después, para lograr tener acceso al desarrollo económico, social, sustentable y humano. Se confirmó la hipótesis de que, en México, durante el período de 2010 a 2022, el mayor número de alumnado de nivel superior puede explicar el 82,6 % de las variaciones experimentadas en el aumento del Producto Interno Bruto (PIB) o crecimiento económico. Se consideraba que los más altos niveles de estudios en el país (doctorado y maestría) influirían de forma determinante en el incremento del PIB (crecimiento económico) y en una mejor posición del Índice de Desarrollo Humano (IDH), pero resultó que la variable más influyente en las regresiones lineales estimadas es la matrícula de nivel licenciatura.

ABSTRACT The consistent underperformance of the Brazilian economy in the 21st century, despite some years of higher gross domestic product (GDP) growth in the 2000s, has coincided with positive outcomes in its financial system. This contradiction is examined in the article through the concepts of hegemony and financialization. The aim is to establish a connection between financial hegemony, economic structure, and aggregate profitability, to identify how the former affects negatively the latter. The weight of the financial sector and its ability to influence economic policies and sustain its gains in different contexts are evaluated. Additionally, the determinants of the profit rate and its relationship with structural factors are examined. The evidence points to a significant influence of financial capital, which, through adverse structural changes, affects long-term profit rate trends, and consequently affects the industry and foreign trade, while also allowing the financial sector to maintain its gains over time.

RESUMEN El bajo rendimiento constante de la economía brasileña en el siglo XXI, a pesar de algunos años de mayor crecimiento del producto interno bruto (PIB) en la década del 2000, ha coincidido con resultados positivos en su sistema financiero. Esta contradicción se examina en el artículo mediante los conceptos de hegemonía y financiarización. El objetivo es establecer una conexión entre la hegemonía financiera, la estructura económica y la rentabilidad agregada, a fin de identificar cómo lo primero impacta negativamente en lo segundo. Se evalúa el peso del sector financiero, así como su capacidad para influir en las políticas económicas y mantener sus ganancias en diferentes contextos. Además, se examinan los determinantes de la tasa de beneficio y su relación con los factores estructurales. La evidencia apunta a una influencia significativa del capital financiero, que mediante cambios estructurales adversos afecta las tendencias de la tasa de beneficio a largo plazo, lo que en consecuencia impacta en la industria y el comercio exterior, y permite al sector financiero mantener sus ganancias con el tiempo.

Abstract This article presents the results of an analysis of the performance of primary health care in São Paulo state over the last decade against a backdrop of financial crisis and health funding cuts. We conducted a time series analysis (2010-2019) of performance indicators across the following dimensions based on an adapted conceptual framework: health service performance, health system, and determinants of health. Annual percentage change was calculated for each indicator using a log-linear model. Performance across the indicators was generally positive; however, there was a decline in performance across indicators of quality of care (congenital syphilis, cesarean section rate and cervical cancer screening). The findings also show a potential rise in demand for public services (due to population aging and a reduction in the percentage of the population with private health insurance) and increase in health expenditure against a backdrop of falling GDP per capita. cuts 20102019 2010 2019 (2010-2019 framework system loglinear log linear model positive however congenital syphilis screening. screening . screening) due insurance capita 2010201 201 (2010-201 201020 20 (2010-20 20102 2 (2010-2 (2010- (2010 (201 (20 (2 (

Resumo O artigo apresenta uma análise do desempenho da APS no estado de São Paulo na última década, em contexto de crise econômica e retração dos investimentos em saúde.

Resumo O artigo apresenta uma análise do desempenho da APS no estado de São Paulo na última década, em contexto de crise econômica e retração dos investimentos em saúde. Utilizaram-se indicadores de desempenho, determinantes em saúde e sistema de saúde, em série temporal (2010 a 2019), a partir de matriz conceitual adaptada. Foram calculadas variações percentuais anuais (VPA) de cada indicador em modelo log-linear. Os indicadores de desempenho apresentaram, no geral, evolução favorável; no entanto, ocorreu piora em indicadores relacionados à qualidade do cuidado (sífilis congênita, partos cesáreos e rastreamento de câncer de colo uterino). Verificou-se, ainda, um potencial aumento das demandas ao SUS (envelhecimento da população e redução da cobertura da saúde suplementar) e aumento das despesas em saúde em contexto de redução do PIB per capita.

Abstract This article presents the results of an analysis of the performance of primary health care in São Paulo state over the last decade against a backdrop of financial crisis and health funding cuts. We conducted a time series analysis (2010-2019) of performance indicators across the following dimensions based on an adapted conceptual framework: health service performance, health system, and determinants of health. Annual percentage change was calculated for each indicator using a log-linear model. Performance across the indicators was generally positive; however, there was a decline in performance across indicators of quality of care (congenital syphilis, cesarean section rate and cervical cancer screening). The findings also show a potential rise in demand for public services (due to population aging and a reduction in the percentage of the population with private health insurance) and increase in health expenditure against a backdrop of falling GDP per capita.

Resumo O artigo tem como objetivo avaliar efeitos econômicos das aquisições da agricultura familiar, no âmbito do Programa Nacional de Alimentação Escolar (PNAE), para os municípios mineiros. De cunho quantitativo, o método escolhido é a regressão linear múltipla. Foram estimados quatro modelos, em que as variáveis econômicas, Produto Interno Bruto (PIB) total, agropecuário, indústria e serviços, são dependentes; o volume de repasses do PNAE (em reais) para agricultura familiar é a variável independente de interesse; e os valores (em reais) do crédito rural por meio do Programa de Fortalecimento da Agricultura Familiar (PRONAF), a produção da agroindústria familiar rural e o número de estabelecimentos da agricultura familiar vinculados a cooperativas ou associações são variáveis independentes de controle. Os principais resultados indicam que a variável PNAE mostrou-se estatisticamente significativa a 1% para os PIBs total, indústria e serviços, e estatisticamente significativo a 10% para o PIB agropecuária, apresentando maior efeito sobre o PIB total. Isso significa que as aquisições da agricultura familiar, por meio do PNAE, exercem efeitos econômicos positivos sobre esses setores e, principalmente, sobre o PIB total. Sugerem-se, para pesquisas futuras, estudos comparativos, aplicações de outras técnicas quantitativas e estudos com abordagens qualitativas. Recomendam-se também pesquisas que contemplem outras lentes teóricas para a percepção dos efeitos da política pública. , (PNAE) mineiros quantitativo múltipla modelos econômicas (PIB total agropecuário serviços dependentes reais interesse PRONAF, PRONAF (PRONAF) controle mostrouse mostrou se 1 10 agropecuária principalmente Sugeremse, Sugeremse Sugerem se, Sugerem-se futuras comparativos qualitativas Recomendamse Recomendam pública (PNAE (PRONAF

Abstract The article aims to evaluate the economic effects of purchases form family farming, under the Brazilian School Feeding Program (PNAE), for the municipalities of Minas Gerais. Of quantitative nature, the chosen method is the multiple linear regression. Four models were estimated, in which the variables are total Gross Domestic Product-GDP (PIB), agriculture and cattle ranching GDP (PIB agropecuário), industry GDP (PIB indústria), and services GDP (PIB serviços). As dependent variables were chosen: the volume of PNAE transfers (in Reais) for family agriculture as the independent variable of interest; the values (in Reais) of rural credit through the Brazilian Program Strengthening Program for Family Farming (PRONAF), the production of family farming agro-industry and the number of family farming establishments linked to cooperatives or associations as the independent control variables. The main results indicate that the independent variable PNAE was statistically significant at 1% for total GDP, industry GDP and services GDP, and statistically significant at 10% for the agriculture and cattle ranching GDP, showing greater effect on total GDP. This means that purchases from family farming , through the PNAE, have positive economic effects on these sectors and, especially, on the total GDP. It is recommended for future researches comparative studies, the application of other quantitative techniques and studies with qualitative approaches. We also recommend research that includes other theoretical lenses for the perception of the effects of public policy.

Resumen El artículo tiene como objetivo evaluar los efectos económicos de las compras de la agricultura familiar, en el marco del Programa Nacional de Alimentación Escolar (PNAE), para los municípios de Minas Gerais, Brasil. De carácter cuantitativo, el método elegido es la regresión lineal múltiple. Se estimaron cuatro modelos, en los que las variables el Producta Interno Bruto (PIB) total, el PIB de la agricultura y la ganadería, el PIB de la industria y el PIB de los servicios, son variables dependientes; el volumen de las transferencias del PNAE (en reales) para la agricultura familiar es la variable independiente de interés; y los valores (en reales) del crédito rural a través del Programa de Fortalecimiento de la Agricultura Familiar (PRONAF), la producción de la agroindustria familiar rural y el número de establecimientos de la agricultura familiar vinculados a cooperativas o asociaciones son las variables de control independientes. Los principales resultados indican que la variable PNAE, resultó estadístícamente significativa al 1% para el PIB total, la industria y los servicios, y estadístícamente significativa al 10% para el PIB agrícola y ganadero, presentando mayor efecto sobre el PIB total. Esto significa que las compras de la agricultura familiar tienen efectos económicos positivos en estos sectores. Se sugiere para futuras investigaciones estudios comparativos, la aplicación de otras técnicas cuantitativas y estudios con enfoques cualitativos. También recomendamos una investigación que incluya otras lentes teóricas para la percepción de los efectos de las políticas públicas. , (PNAE) Gerais Brasil cuantitativo múltiple modelos (PIB total ganadería servicios dependientes reales interés PRONAF, PRONAF (PRONAF) independientes 1 10 ganadero sectores comparativos cualitativos públicas (PNAE (PRONAF
