ABSTRACT Objective: To evaluate the agreement between body mass index (BMI) parameters applied to children aged six to ten years in the city of Montes Claros (MG), Brazil with national and international criteria, also calculating their sensitivity and specificity regarding excess weight screening. Methods: A sample comprising 4151 children aged six to ten years was assessed, with height and body mass determined for BMI calculation. The obtained values were classified according to cutoff points established by the World Health Organization (WHO), International Obesity Task Force (IOTF), Centers for Disease Control and Prevention (CDC), Conde & Monteiro, and a recent local proposal. The agreement index between the mentioned criteria was calculated and thereafter the sensitivity and specificity. Results: The local proposal was proven to be highly consistent in most combinations, especially concerning the excess weight criteria of the World Health Organization (WHO) (k=0.895). Regarding excess weight, the local proposal presented sensitivity and specificity values of 0.8680 and 0.9956, respectively, indicating high BMI discrimination power. Conclusions: The locally applied BMI parameters for children aged six to ten years represent a valid, highly viable and practical proposal for excess weight screening in this population group, improving professional decision-making in their follow-up.

ABSTRACT A study was undertaken comparing the water requirements of two common bean ( Phaseolus vulgaris L.) cultivars to generate specific recommendations aimed at optimizing water use. To accomplish this work, the agronomic performance, responsiveness to water and water productivity of these two common bean cultivars of determinate and indeterminate growth habits were identified. The 2-year experiment was carried out during the winter growing season in the southeast of Brazil. Cultivars IAC Imperador, with an early season of determinate growth habit, and IPR Campos Gerais, having a mid-season of indeterminate growth habit, were subjected to five irrigation levels (54, 70, 77, 100, and 132 % of the crop evapotranspiration). Water deficit affected agronomic performance, reducing plant height (by up to 29 %), leaf area index (by up to 40 %), soil cover fraction (by up to 28 %), and grain yield (GY - by up to 31 %), in both cultivars. In contrast, excess water was more detrimental to cultivar IAC Imperador. Cultivar IPR Campos Gerais produced 18 % more than GY, showing superior water productivity and response to irrigation depth than IAC Imperador. Out of all the variables evaluated, the soil cover fraction correlated the most with grain yield in both common bean cultivars during the 2-year study. In other words, cover fraction evaluation in common bean allows for estimating crop production potential, which helps producers and technicians in their decision making regarding management practices. Thus, a cultivar directly affects water use in common bean production, thereby suggesting the need for a or water conservation strategy and sustainability of irrigated common bean production. L.

ABSTRACT The cultivation of Coffea arabica L. in a low-altitude region is a sustainable alternative for diversifying the income of farmers. On account of the variability of available cultivars, the use of indirect selection through initial vegetative development may be an auxiliary tool for identifying the most suitable genotypes for this environment. This study aimed to identify the dwarf Arabica coffee cultivars with better initial development in a low-altitude region and the morphological traits with greater relevance for the early selection of cultivars with high yield potential. The experiment was installed in the northeast of São Paulo, Brazil. The experimental design used was randomized blocks with four replications. The treatments consisted of 17 dwarf Arabica coffee cultivars. There is variability among dwarf Arabica coffee cultivars for initial vegetative development. The growth and increase in the number of nodes of the plagiotropic branch can be used in early selection to identify cultivars with greater yield potential. The cultivars IAC Obatã 4739, Obatã IAC 1669-20, and Tupi IAC 1669-33 present higher initial vegetative performance in low-altitude environments. The results obtained are useful to breeders and producers for choosing the cultivars best adapted to cultivation in this environment.

RESUMO O uso de índices de vegetação apresenta bom potencial para a predição da produtividade de diversas culturas, porém fatores como a época de avaliação, cultivares e fenologia da planta podem influenciar na performance de modelos preditivos. O objetivo do trabalho foi avaliar e comparar a precisão de estimativa da produtividade do feijoeiro, em função do índice de vegetação NDVI, utilizando modelos individuais por cultivar e geral com todas as cultivares. Foram avaliadas as cultivares IAC Imperador e IPR Campos Gerais, de hábitos de crescimento determinado e indeterminado, respectivamente. Foram submetidas a diferentes manejos de fornecimento de nitrogênio, a fim de proporcionar variação da produtividade. Foram realizadas avaliações do NDVI ao longo do ciclo da cultura, em 6 datas, durante estádios vegetativos e reprodutivos. A produtividade de grãos do feijão pode ser estimada com elevada performance em função do índice de vegetação NDVI, obtendo-se R2 de até 78% e erro médio próximo de 350 kg ha-1. Os melhores ajuste de estimativa são obtidas em estádios fenológicos reprodutivos do feijão, especialmente após o florescimento da cultura (R6). Modelos generalistas, compostos por dados de mais de uma cultivar, apresentam precisão semelhante e, em alguns casos, superior aos modelos ajustados para cada cultivar, demonstrando a viabilidade da utilização de um mesmo modelo para vários genótipos.

ABSTRACT The use of vegetation indices has good potential for predicting the productivity of several crops, but factors such as the time of assessment, cultivar, and plant phenology can influence the performance of predictive models. The objective of this study was to evaluate and compare the precision of estimating the common bean grain yield, according to the normalized difference vegetation index (NDVI), using individual models per cultivar and a general model with all cultivars. The cultivars IAC Imperador and IPR Campos Gerais, with determined and indeterminate growth habits, respectively, were evaluated. They were subjected to different nitrogen management methods to provide grain yield variability. NDVI evaluations were conducted throughout the culture cycle on six dates during the vegetative and reproductive stages. The common bean grain yield was estimated with high precision as a function of NDVI, obtaining a precision of up to 78% and an average error close to 350 kg ha-1. The greatest fit of estimation was obtained in the phenological reproductive stages of beans, especially after crop flowering. General models, composed of data from more than one cultivar, had similar precision and, in some cases, superiority to the fitted models for each cultivar, demonstrating the feasibility of using the same model for several genotypes.

ABSTRACT The demand for specialty coffees in the national and international market grows and generates an excellent opportunity for the exploration of new business. The cup quality of coffee is defined by the genetic predisposition of varietal groups, effects of the production environment, crop management, and form of post-harvest processing. Genotypes of Yellow Bourbon have already shown a predisposition to the production of excellent cup quality, but it may differ in sensory attributes and cup quality. The aim of this article was to evaluate the agronomic and qualitative performance of Yellow Bourbon strains from the Active Germplasm Bank of the Agronomic Institute of Campinas, in order to identify the best genotypes for the production of specialty coffees. The experiment was conducted in São Sebastião da Grama, SP, Brazil, at 1,100 meters of altitude in a medium-textured Ultisol. Treatments consisted of 14 strains of Yellow Bourbon, arranged in a randomized block design with three replicates. Field, post-harvest and laboratory evaluations were carried out. The strains IAC J3-1, IAC J9-16 and IAC J19-18-10 stood out in terms of yield values and sensory quality above the average of the studied group. The strains IAC J9-16 and IAC J19-18-10 showed predominance of floral and honey nuances, respectively, indicating that they may have high potential to express these characteristics in the beverage. The results suggested that there are Yellow Bourbon strains suitable for production and with superior cup quality, which highlights the importance of the appropriate choice of genotypes for the production of differentiated specialty coffees.

Abstract Maize has a high nitrogen (N) demand; as a result, more sustainable alternatives are needed to reduce demand for mineral fertilizers. The hypothesis is that the agronomic perfor mance of maize genotypes diverges in their potential when subjected to different supplies of N. This study aimed to evaluate and characterize the agronomic performance of maize geno types submitted to topdressing nitrogen fertilization and inoculation with Azospirillum brasilense and select the best genotypes within each management. An experiment was conducted in the second season of 2017, in Jaboticabal-SP (Brazil), using 48 maize geno types in a randomized block design. Treatments consisted of: 1) application of 140 kg ha-1 nitrogen, using urea as mineral fertilizer; 2) A. brasilense inoculation via soil, at a rate of 600 mL ha-1, as biological fertilization. Grain yield and agronomic traits were evaluated. The data were subjected to analysis of variance (F-Test), means were compared by Scott-Knott test at 5% probability, and multivariate statistical analysis was performed by principal component analysis. The maize genotypes showed contrasting agronomic performance in relation to the nitrogen supplies evaluated. Inoculation with A. brasilense via soil has a significant effect on increasing maize grain yield, making it a viable and more sustainable alternative in the supply of N. The choice of the genotype is an essential factor for the successful use of mineral nitrogen fertilization or A. brasiliense inoculation.

Resumen El maíz tiene una alta demanda de nitrógeno (N), como resultado, se necesitan alter nativas más sostenibles para reducir la demanda de fertilizantes minerales. La hipótesis es que el comportamiento agronómico de los genotipos de maíz diverge en su potencial cuando se someten a diferentes suministrados de N. Este estudio tuvo como objetivo evaluar y caracte rizar el rendimiento agronómico de los genotipos de maíz sometidos a fertilización nitro genada e inoculación con Azospirillum brasilense y seleccionar los mejores genotipos dentro de cada manejo. Se realizó un experimento en la segunda temporada de 2017, en Jabotica bal-SP (Brasil), utilizando 48 genotipos de maíz en un diseño de bloques al azar. Los trata mientos consistieron en: 1) aplicación de 140 kg ha-1 de nitrógeno, utilizando urea como fertilizante mineral; 2) Inoculación de A. brasilense vía suelo, a razón de 600 mL ha-1, como fertilización biológica. Se evaluaron el rendimiento de granos y los rasgos agronómicos. Los datos se sometieron a análisis de varianza (prueba F), y las medias se compararon mediante la prueba de Scott-Knott con una probabilidad del 5%, y el análisis estadístico multivariado se realizó mediante análisis de componentes principales. Los genotipos de maíz mostraron un comportamiento agronómico contrastante en relación con los suministrados de N evaluados. La inoculación con A. brasilense vía suelo tiene un efecto significativo en incrementar el rendi miento de granos de maíz, convirtiéndolo en una alternativa viable y más sustentable en el sumi nistrado de N. La elección del genotipo es un factor esencial para el uso exitoso de la fertilización con nitrógeno mineral o la inoculación con A. brasiliense.

More sustainable practices involving biological nitrogen fixation (BNF) and the use of portable chlorophyll meter in fertilization management are promising to increase nitrogen (N) use efficiency in the common bean crop. This study aimed to monitor N managements using a portable chlorophyll meter and its effects on agronomic attributes of Carioca-type common bean cultivars with indeterminate and determinate growth habits ('IPR Campos Gerais' and 'IAC Imperador'). The experiment was carried out in a randomized block design (RBD), in a 2 × 9 factorial scheme, with four replicates. The first factor consisted of the cultivars and the second factor of the N management. The data were subjected to analysis of variance by F test and, when necessary, the means were grouped by the Scott-Knott test at 5% probability level. The use of portable chlorophyll meter is a viable alternative for N monitoring and management in common bean, allowing the reduction of top-dressing N application, regardless of the cultivar used.

Las prácticas más sostenibles que involucran la fijación biológica de nitrógeno (BNF) y el uso del clorofilómetro portátil en el manejo de fertilizantes son prometedoras para aumentar la eficiencia del uso de nitrógeno (N) en el cultivo de frijol común. El objetivo fue monitorear el manejo de N con el clorofilómetro portátil y sus efectos sobre los atributos agronómicos de los cultivares de frijol carioca de crecimiento indeterminado y determinado ('IPR Campos Gerais' e 'IAC Imperador'). El experimento se implementó en un diseño de bloques al azar (DBC), en un esquema factorial 2 x 9, con cuatro repeticiones. El primer factor consistió en cultivares, y el segundo factor fue el manejo de N. Los datos fueron sometidos a análisis de varianza por la prueba F, y cuando fue necesario los medios se agruparon por la prueba de Scott-Knott con un 5% de probabilidad. El uso clorofilómetro portátil es una alternativa viable para el monitoreo y manejo del N en el frijol común, permitiendo la reducción de la aplicación del nutriente en la cobertura, independientemente del cultivar utilizado.

Resumo Neste artigo procuramos identificar um fenômeno discursivo emergente na cidade de São Paulo: o cicloativismo, que passa de um emaranhado de vozes desconexas a uma "fala articulada" no campo de embates sobre os sentidos da mobilidade urbana. O cicloativista constitui-se em uma nova posição de sujeito na medida em que abre um antagonismo ao discurso estabilizado em torno da hegemonia do transporte individual motorizado. O artigo se desdobra em quatro partes: a) uma descrição da cidade voltada ao automóvel como horizonte semanticamente normal; b) a categorização da política como processo de articulação de "falas", nos termos de Rancière; c) a análise discursiva de peças comunicacionais veiculadas em websites especializados em ciclomobilidade; d) considerações sobre um processo de reabsorção parcial da atividade ciclística nas cadeias de equivalência simbólica do liberal-capitalismo.

Abstract In this paper we intend to identify an emergent discursive phenomenon in the city of São Paulo: the bike activism. It rises from a medley of disconnected voices towards an "articulated speech", in the discursive field about the meanings of the urban mobility. The bike activism constitutes a new subject position insofar as it defies, as an antagonism, the stabilized discourse related to the hegemony of the individual motorized transportation. The paper is divided into four sections: a) a description of the automobile city as a semantically normalized horizon; b) the conceptualization of politics as an articulation of speech, in Rancière terms; c) the discursive analysis of texts published in bike-mobility specialized websites; d) considerations about the partial re-absorption of the cycling into the symbolical equivalence chains of liberal-capitalism.

ResumoEsta resenha apresenta o livro Heidegger and the Media, dos autores David J. Gunkel e Paul A. Taylor, publicado em inglês pela editora Polity Press. O objetivo é oferecer aos leitores uma visão crítica sobre os principais pontos tratados na obra. O livro, dividido em quatro capítulos, além de introdução e conclusão, busca num primeiro momento abordar a importância do pensamento heideggeriano para o campo midiático; passa em seguida aos problemas conceituais da "verdade" e do "objeto" nos termos propostos pelo filósofo alemão; termina considerando a influência que a obra de Heidegger teve sobre os mais devotados pensadores da mídia, a exemplo de Mcluhan.

AbstractThis review presents the book Heidegger and the Media, by David J. Gunkel and Paul A. Taylor. It offers to the readers a critical analysis about the main points covered by the authors. The book is organized in four chapters, besides an introduction and a conclusion. In the beginning, it approaches the relevance of Heideggerian thought for the media field. Then, it faces the problems concerning the 'truth' and the 'object' according to the terms proposed by the German philosopher. Finally, the book epitomizes the influence of Heidegger's works over thinkers more devoted to media studies as Mcluhan.

O presente estudo analisa a interface entre dois campos disciplinares: finanças e pesquisa operacional. Nesse sentido integra duas abordagens de análise de investimentos - técnica e fundamental, bem como as preocupações de um investidor no momento de alocação de recursos em uma estratégia de investimento em ações do tipo Buy & Hold. De caráter exploratório e descritivo, o estudo utiliza como instrumento de intervenção a Metodologia Multicritério de Apoio à Decisão (MCDA). Como resultados, ficou evidenciado que o instrumento de intervenção utilizado, aliado à uma estratégia de investimentos pré-definida, foi capaz de suportar o decisor no momento de alocação de recursos, gerando uma rentabilidade de 25.14% no acumulado, contra uma rentabilidade negativa de -13.41% do IBOVESPA no mesmo período. Com o objetivo de conferir a robustez dos resultados, foram realizadas regressões do modelo CAPM tanto com dados semanais quanto diários, sendo que o teste t realizado nos coeficientes da regressão se mostrou significativo à 1% para o retorno anormal dos dados semanais e à 0.1% para o retorno anormal dos dados diários, além disso, a estatística t foi positiva nos dois casos, indicando a presença de um retorno anormal positivo, ou seja, a carteira aqui proposta superou o seu benchmark.

The present study analyzes the interface between two disciplinary fields - finance and operational research. In this sense, it integrates two approaches to investment analysis - fundamental and technical, as well as an investor's concern at the time of resources allocation in a Buy & Hold investment strategy. The study uses the Multicriteria Decision Aid (MCDA) as an instrument of intervention. As for results, it was evident that the instrument of intervention used, together with a pre-defined investment strategy, was able to support the decision maker at the time of allocation of resources, generating an accumulated return of 25.14 % in the period, compared with a negative return -13.41% of the Bovespa index in the same period. In order to check the robustness of results, regressions were performed with both the CAPM model as daily and weekly data, and the t test performed on the coefficients of the regression was significant at 1% for the abnormal return of weekly data and 0.1% for the return of abnormal daily data; in addition, the t-statistic was positive in both cases, indicating the presence of abnormal positive feedback, i.e., the portfolio proposed here outperformed its benchmark.

Este estudio analiza la relación entre dos disciplinas, a saber, las finanzas y la investigación operativa. En consecuencia, integra dos enfoques para el análisis de inversiones - fundamental y técnica-, así como las preocupaciones de un inversionista en el momento de la asignación de los recursos, con el fin de analizar los resultados de una estrategia de inversión en acciones Buy & Hold. El estudio utiliza como herramienta de intervención el MCDA (Ayuda a la Decisión Multicriterio). Como hallazgos, se hizo evidente que el instrumento de intervención utilizado, junto con una estrategia de inversión previamente definidos, fue capaz de apoyar la toma de decisiones en el momento de la asignación de los recursos, generando una rentabilidad del 25.14% en el año, frente a una rentabilidad negativa -13.41% del índice Bovespa en el mismo período. Con el fin de comprobar la solidez de los hallazgos, las regresiones se realizaron con el CAPM tanto como datos de diario y semanal, y la prueba de la t realizada en los coeficientes de la regresión fue significativa al 1% para el rendimiento anormal de los datos semanales y 0.1% para el rendimiento anormal de los datos diarios, además, la estadística t fue positiva en ambos casos, lo que indica la presencia de retroalimentación positiva anormal, es decir, la cartera propuesta aquí batió a su referencia.

OBJETIVO: Avaliar a tendência de mortalidade por pneumonia em crianças brasileiras até 4 anos de idade no período de 1991 a 2007. MÉTODOS: Foi realizado um estudo retrospectivo baseado em banco de dados do Departamento de Informática do Sistema Único de Saúde (DATASUS), do qual foram extraídos o número de óbitos por pneumonia e a população residente de até 4 anos de idade nas cinco regiões brasileiras e no país como um todo. O coeficiente de mortalidade foi calculado pelo número de óbitos por pneumonia dividido pela população, multiplicando por 1.000 na faixa etária menor de 1 ano e por 10.000 na faixa etária de 1 a 4 anos. Utilizou-se o teste de regressão linear para avaliar a tendência temporal de mortalidade. RESULTADOS: Observou-se um decréscimo significativo de mortalidade por pneumonia no período estudado em ambas as faixas etárias e em todas as regiões do país. No Brasil como um todo, a redução média anual dos coeficientes de mortalidade na população menor de 1 ano e naquela entre 1 e 4 anos foi de 0,12 e 0,07, respectivamente. As Regiões Sul e Sudeste apresentaram as maiores reduções (-0,14 e -0,18 para < 1 ano; -0,07 e -0,09 para 1 a 4 anos). As menores reduções foram nas Regiões Norte e Nordeste (-0,04 e -0,07) nas crianças menores de 1 ano, e nas Regiões Norte e Centro-Oeste (-0,03 e -0,04) na faixa etária entre 1 e 4 anos. CONCLUSÕES: Houve uma redução significativa na mortalidade por pneumonia em crianças até 4 anos de idade em todo o país no período de 1991 a 2007, porém, uma discrepância entre as diferentes regiões permanece em evidência.

OBJECTIVE: To evaluate the trend of pneumonia mortality in Brazilian children aged 4 years and younger from 1991 to 2007. METHODS: We conducted a retrospective study based on the database of the IT Department of the Brazilian Unified Health System (DATASUS), from which we obtained the number of deaths from pneumonia and the population aged 4 years and younger living in the five Brazilian regions and in the whole country. Mortality rate was calculated according to the number of deaths from pneumonia divided by the population, multiplied by 1,000 for the age group under 1 year old and by 10,000 in the age group from 1 to 4 years. The linear regression test was used to evaluate the time trend of mortality. RESULTS: There was a significant decrease in pneumonia mortality rates during the study period in both age groups and all regions of the country. In Brazil, the mean annual reduction in mortality rates in the population under 1 year old and between 1 and 4 years was 0.12 and 0.07, respectively. The South and Southeast regions showed the greatest reductions (-0.14 and -0.18 for < 1 year and -0.07 and -0.09 for 1 to 4 years). The smallest decreases were in the North and Northeast regions (-0.04 and -0.07) in children younger than 1 year, and in the North and Central West (-0.03 and -0.04) in the age group between 1 and 4 years. CONCLUSIONS: There was a significant reduction in pneumonia mortality in children aged 4 years and younger across the country from 1991 to 2007; however, a discrepancy between the different regions remains evident.
