A influência dos ciclos políticos nos investimentos públicos em infraestrutura: um estudo nos estados brasileiros no período de 2003 a 2014
Authors: Gonçalves Luciano Gomes , Funchal Bruno , Bezerra Filho João Eudes
Published: September 2017

Resumo Este artigo tem como objetivo avaliar se os ciclos políticos em conjunto com viés ideológico impactam significativamente as decisões de alocação de recursos públicos em investimentos de infraestrutura nos estados brasileiros. Para atingir tal objetivo, utilizamos informações em nível estadual de 2003 a 2014 para capturar três ciclos eleitorais. Como abordagem metodológica utilizamos regressão em painel com efeitos fixos, com o objetivo de detectar características estaduais não observáveis e invariantes no tempo. Os resultados encontrados mostram a existência de influência do ciclo eleitoral se considerarmos as diferenças ideológicas interagindo com os ciclos eleitorais. Os resultados apontam que partidos de esquerda e de centro tendem a investir mais em infraestrutura em períodos pré-eleitorais se comparados com partidos de direita. Esse resultado contribui para a literatura evidenciando que ciclos podem ser mais influenciados dependendo do partido que está governando. Foi identificado adicionalmente um resultado contraintuitivo relativo ao impacto negativo nos gastos em infraestrutura quando o governador é do mesmo partido do presidente. Para essa variável, esperava-se um impacto positivo.
Parcerias público-privadas (PPP) em megaeventos esportivos: um estudo comparativo da provisão de arenas esportivas para a Copa do Mundo Fifa Brasil 2014
Authors: Reis Cláudio José Oliveira dos , Cabral Sandro
Published: September 2017

Resumo Em função do caráter recente de sua adoção, pouco se sabe ainda sobre o desempenho de projetos de parcerias público-privadas (PPP) e seus condicionantes. O presente estudo tem por objetivo investigar o comportamento das PPP e suas variações contratuais na provisão de arenas esportivas para a Copa do Mundo Fifa Brasil 2014 numa perspectiva comparada às modalidades de provisão pública tradicional e estritamente privada. Para tanto, utilizou-se uma abordagem metodológica qualitativa, inserida numa perspectiva exploratória por meio de estudo de casos múltiplos. Os resultados sugerem que os projetos de PPP geraram value for money para a administração pública brasileira, sobretudo referente aos aspectos de prazo, custos, receitas diversificadas e processo licitatório em decorrência das estruturas de incentivos oriundas dos contratos de PPP e da própria flexibilidade gerencial inerente aos atores privados.

ABSTRACT The objective of the present research is to characterize the phytotoxic activity of geopropolis from the Jandaira bee (Melipona subnitida Ducke) in the state of Ceará in Northeast Brazil and to analyze its effects. Extracts were prepared in 80% v/v grain alcohol at 0.25, 0.5, 0.75, and 1.0%. Their effects were determined on seed germination, radicle elongation, and hypocotyl growth of the pasture weeds malícia (Mimosa pudica) and mata-pasto (Senna obtusifolia). Extract phytotoxicity varied as functions of plant species, application dosage, and plant organ. M. pudica was more sensitive to the inhibitory effects of geopropolis than S. obtusifolia. There was a phytotoxic effect of 50% (PE50) for S. obtusifolia in terms of seed germination and in rootlet development near the maximum applied concentrations. M. pudica had PE50 and PE90 at the minimum concentration (0.25%) and near the maximum (1.00%), respectively. Thus, geopropolis extracts from the Jandaira bee (M. subnitida) are potentially phytotoxic to certain plant species.

ABSTRACT In Brazil, species of the genus Liriomyza are widely distributed and have economic importance as they cause damage to at least 14 plant families, especially Solanaceae, Cucurbitaceae, Asteraceae, and Fabaceae. Studies suggest existence of a species complex within this genus, based on the presence of morphological similarities among the species Liriomyza trifolii (Burgess), L. sativae Blanchard and L. huidobrensis (Blanchard). The present study aimed to use DNA barcoding to establish new distribution records of L. sativae in distinct regions in Brazil, determine intra- and inter-population genetic diversity, and reconstruct the phylogeny of Liriomyza species using the DNA barcode sequences. Identity values were between 97% and 99%, confirming that all the examined Brazilian populations belonged to the species L. sativae. Phylogenetic analyses indicated the presence of a single clade of L. sativae, composed of seven populations. Intra-population analysis on individuals of these populations indicated low levels of nucleotide and haplotype diversity. The haplotype network indicated presence of only 14 haplotypes distributed among the Brazilian populations. The genetic similarities shared by the Brazilian populations of L. sativae suggest that these populations are closely related. Genetic patterns observed among populations of L. sativae might be associated with bottleneck events or founder effect during establishment of this leafminer in Brazil.
CARBON SOURCES AND C:N RATIOS ON WATER QUALITY FOR NILE TILAPIA FARMING IN BIOFLOC SYSTEM
Authors: SILVA UGO LIMA , FALCON DARIO ROCHA , PESSÔA MAURÍCIO NOGUEIRA DA CRUZ , CORREIA EUDES DE SOUZA
Published: September 2017

ABSTRACT The use of biofloc technology (BFT) can improve fish production in regions with low water availability. Therefore, information on dynamics of water quality is essential for success in fish rearing. Thus, the objective of the present study was to evaluate the water quality for Nile tilapia farming in a system without water exchange, during the fingerling stage, using different sources of carbon and C:N ratios. A completely randomized experimental design was used in a 2x3 factorial arrangement, with two carbon (C) to nitrogen (N) ratios (10:1 and 20:1) and three carbon sources (sugar, molasses and cassava starch). The C:N ratio and carbon source affected the variables alkalinity, settleable solids (SS), turbidity and total suspended solids (TSS), showing significantly higher values at C:N ratio of 20:1 (P < 0.05). The best carbon source for microbial floc formation were the molasses and sugar, under C:N ratios of 10:1 and 20:1. The stability of the monitored water quality parameters occurred from 6 to 7 weeks of rearing. The growth performance of Nile tilapia in BFT system fertilized with different organic carbon sources was not significantly different (P < 0.05) between treatments. The use of molasses to fertilize BFT systems can reduce costs of production in regions where this product is available.

ABSTRACT This study aimed to define areas suitable, and the irrigation water requirement for, cultivation of Tanzania guineagrass in the state of Ceará, Brazil. Tanzania guineagrass yield was estimated by a mathematical model, which considers the crop actual evapotranspiration, resulting from the crop climatological water balance. The water requirement throughout the year was estimated for soils with a water holding capacity of 20 (shallow soils), 40 (sandy soils), 60 (soils with medium texture) and 100 mm (clay soils). The relative frequency of occurrence of monthly productions greater than 2,750 kg DM ha-1 month-1 was obtained for different areas in Ceará, representative of most of the state's economic mesoregions. Tanzania guineagrass annual yields in the state of Ceará were between 20,000-30,000 kg DM ha-1 year-1. During the rainy season, the productive potential varies with the economic mesoregion, which presents different climatic conditions. The state of Ceará is only suitable for the rainfed production of Tanzania guineagrass for 4 months each year, predominantly from February to May, while weather conditions do not favor the development of this grass in the remaining months.

ABSTRACT The benefits of integrating agricultural components into silvopastoral systems are widely known, but the limited knowledge about ecological processes in the establishment phase impedes the use of this technology. The objective of this study was to evaluate interactions between fruit tree species and the sward layer under canopies of trees in the establishment phase of silvopastoral systems in Mato Grosso, Brazil. The experiment was implemented in October 2013, with an evaluation period from January to July 2015. The systems were composed of eight fruit trees intercropped with Tifton 85 grass. A completely randomized block design was adopted, with two replications per area per treatment. We evaluated the agronomic performance of the fruit trees, the categories of the light environment, and the plant accumulation under the canopies. The acerola fruit trees of the variety Roxinha had higher Leaf area index (LAI) and Light interception (LI) values, showing a denser canopy with small porosity and the lowest light quality available to the plants beneath the canopy (lower red/far-red ratio), thereby decreasing plant accumulation under trees. The guava fruit trees showed higher growth rates than the other fruit trees, but lower LAI and LI values and a higher red/far-red ratio, allowing higher plant growth under the canopy. Cajá trees showed a similar behavior; however, this species is deciduous, which limits its potential use in integrated systems. Banana and coconut trees were highly dependent on irrigation during the dry season. The remaining species showed an adequate growth and potential to control plant species growth under their canopies.

Published: September 2017

Abstract Objectives: To identify the frequency of change of chlorhexidine-impregnated gel dressings applied in central venous catheter insertion sites, describe reasons for dressing changes, and identify the amount of dressings used per adult patients admitted to an intensive care unit. Methods: Descriptive study consisting of daily record of occurrence evaluation, reason for dressing change and quantity used per patient, between April and December 2014. Descriptive statistical analysis was used. Results: A total of 159 dressings were applied at the insertion site of 64 central venous catheters whose mean frequency of dressing changes was 3.04 days. The mean number of dressing per patient was 3.1, but 83 unscheduled changes occurred before 7 days of stay, due to detachment, wetness, soiling, and loss of dressing. Conclusion: The frequency of dressing changes was less than seven days, resulting in greater quantities of dressings per patient. Detachment was the most common reason for unscheduled dressing changes.
A poesia de Manuel Bandeira: a crítica de Mário de Andrade e Sérgio Buarque de Holanda
Authors: MORAES RICARDO GAIOTTO DE
Published: September 2017

RESUMO A poesia de Manuel Bandeira, um dos mais profícuos poetas brasileiros do século XX, interessou tanto à crítica literária de Mário de Andrade quanto à de Sérgio Buarque de Holanda. O objetivo deste artigo é analisar os critérios que sustentam as críticas de Mário de Andrade e Sérgio Buarque à poesia de Manuel Bandeira, tendo como ponto de partida a afirmação da trajetória artística sincera do poeta. No caso de Mário de Andrade, tal conceito parece retomar as reflexões sobre a técnica da poesia desenvolvidas sistematicamente em “O artista e o artesão”; no caso de Sérgio Buarque, parece figurar como um dos combustíveis para a revolução contra a “cordialidade” brasileira, conforme definida em Raízes do Brasil.
Os “Poemas da Negra”, uma leitura a contrapelo da “poesia do senhor do engenho”
Authors: GRILLO ANGELA TEODORO
Published: September 2017

RESUMO O presente artigo dedica-se a uma leitura dos doze “Poemas da Negra” de Mário de Andrade, escritos em 1928 e publicados em 1930 na obra Remate de males. A análise e a interpretação do conjunto amoroso nascem dos estudos do manuscrito Preto no acervo do escritor (Grillo, 2010), salvaguardado no Instituto de Estudos Brasileiros (IEB-USP), e seguem indicações de Gilda de Melo e Souza (2005). A estudiosa aponta para que se faça uma leitura dos poemas a contrapelo do que ela denomina “poesia do senhor do engenho”. De fato, em um dos mais belos versos amorosos de Mário de Andrade, o poeta desenvolve na poesia modernista uma nova dicção a respeito da negra, na medida em que o eu lírico a eleva a um plano cósmico, igualando o eu poético e a musa de azeviche.

Authors: El Haffar I. , Blanc M. , Thorel L.
Published: September 2017

The impact of installation methods on pile axial capacity is studied using centrifuge model testing. Compression and tension tests are carried out on model piles jacked at 1g or at 100g in dense Fontainebleau NE34 sand. The pile total compression capacity and shaft and tip resistance are analysed and compared with the current design standards used in offshore engineering. These results show that the axial capacity of the tested piles is clearly underestimated. Pile total tension capacities are also studied. A significant increase in tension capacity is observed in cyclically jacked piles unlike piles monotonically jacked at 100g.
Leitura dos Desenhos de um Serial Killer: Um Relato de Experiência

Published: September 2017

O texto apresenta o resultado do primeiro Laudo Arteterapêutico Jurídico do Brasil realizado a partir da leitura de desenhos de um serial killer. O objetivo deste artigo é relatar a experiência da entrevista realizada com o acusado e a leitura dos desenhos encontrados em sua pose no momento da detenção, para fins de auxiliar na interpretação e elaboração do laudo, propiciando entendimentos em relação à história de vida do sujeito e suas conflitivas, auxiliando na compreensão do magistrado sobre o processo em questão. O relato se refere a um brasileiro, adulto jovem, solteiro, sexo masculino, atualmente preso por homicídios de crianças e adolescentes, ocultação de cadáveres e, em alguns casos, violência sexual post-mortem. Procura-se mostrar os significados dos sete desenhos que fizeram parte do processo judicial e que cobram importância ao trazer à tona conteúdos internos do assassino. A avaliação dos desenhos foi feita mediante duas leituras, uma do próprio acusado que referiu gostar de desenhar, outra pela Leitura Transtextual Singular de Imagens (ORMEZZANO, 2009). Pode-se observar na leitura dos desenhos sinais de um sujeito sem capacidade de empatia, com sintomas de psicopatia havendo repetida manifestação de uma negação dos conteúdos inconscientes, levando-o por diversas vezes à um comportamento ambíguo que ora ocupa o papel de vítima, ora ocupa o papel de algoz. Nesse sentido, esta experiência pode contribuir de modo relevante para as múltiplas áreas que realizam interfaces nas ciências forenses e de saúde mental.
Ciberactivismo y olas de agitación comunicativa. Consideraciones etnográficas
Authors: Aguilar-Forero Nicolas
Published: September 2017

En este artículo se presentan algunos resultados de un trabajo etnográfico colaborativo, multisituado y experimental que tuvo lugar durante los años 2012 y 2014, y que giró en torno a las prácticas comunicativas de la organización Hijos e Hijas por la Identidad y la Justicia contra el Olvido y el Silencio (H.I.J.O.S.). En particular, se analizan las características del ciberactivismo del nodo de H.I.J.O.S. en Bogotá y se ilustra cómo la apropiación politizada de distintas plataformas de Internet por parte de este colectivo favorece la circulación de contenidos, la coordinación de acciones e incluso la transformación constructiva de sus conflictos internos. El análisis, desarrollado en diálogo con ciertas claves interpretativas derivadas de la antropología de los mundos virtuales, pretende además promover una reflexión acerca de los desplazamientos necesarios y los retos del trabajo etnográfico, de cara al estudio del ciberactivismo en el mundo contemporáneo.
Resituando el diario/bitácora/sketch en la producción de conocimiento y sentido antropológico
Authors: Cortés Severino Catalina
Published: September 2017

El objetivo principal de este artículo es situarme desde el “giro corporal” en “lo visual”, lo que nos lleva a ubicarnos no en un tipo de observación a la distancia, desprendida y objetiva sino desde otra forma de mirar y relacionarnos con el mundo; no como algo ajeno, sino el mundo que nos afecta y al cual nosotros afectamos con nuestras miradas. Así, el cuerpo es el eje articulador, es decir, reconocer y reposicionar a los cuerpos como eje fundamental para renovar la investigación antropológica y artística en nuestro continente. Desde estos planteamientos, el propósito de este artículo es visibilizar, articular y compartir algunas de mis experiencias en el quehacer etnográfico a partir de tres trabajos realizados desde el diario/bitácora/sketch, al igual que reflexionar sobre el diario como práctica narrativa y visual.
Cultura autóctona: curaduría como proceso etnográfico en la escena del arte cubano actual
Authors: González Celia Irina
Published: September 2017

Esta investigación participa de la discusión sobre la urgencia de la problematización del trabajo de campo para la producción de conocimiento antropológico a través de nociones provenientes de las artes visuales como diseño, instalación y curaduría. El trabajo de campo fue realizado en La Habana bajo la noción de práctica curatorial como práctica etnográfica, método y modo de producción teórica. La práctica curatorial se concretó en una exhibición nombrada Cultura autóctona, con el objetivo de comprender la escena actual del arte cubano y su repercusión en la producción de prácticas involucradas con su contexto social potencialmente críticas. El diseño de la operación de encuentro como parte del proceso de la práctica curatorial aportó elementos a la actual discusión de la antropología visual, al entender la imagen como parte de procesos de relacionamiento, más que de descripción.
ANÁLISE DO IMPACTO DO CRÉDITO RURAL NA PRODUÇÃO AGRÍCOLA BRASILEIRA NO PERÍODO 2006-2014
Authors: Medeiros Angélica Pott de , Bender Filho Reisoli , Vieira Kelmara Mendes , Ceretta Paulo Sergio
Published: September 2017

Num cenário em que as políticas de governo têm buscado suportar o crescimento do setor agrícola, sobremaneira a partir de políticas direcionadas, o estudo objetivou examinar o impacto da concessão de crédito rural sobre a produção agrícola, considerando o período 2006-2014. Para isso, fez-se o uso da metodologia do Vetor de Correção de Erros (VEC), a qual possibilita analisar as relações de curto e de longo prazo. Os resultados indicaram que, no longo prazo, impactos positivos e mais expressivos sobre a produção agrícola decorreriam da ampliação da área plantada, enquanto que, em curto prazo, o aumento passaria pelo investimento em fertilizantes e pela maior utilização de máquinas e implementos. Por outro lado, embora a concessão de crédito rural não tenha apresentado relação significativa, não se pode desconsiderar seus efeitos indiretos sobre a produção agrícola.

Published: September 2017

O descarte inadequado dos resíduos gerados em ETA’s e/ou ETE’s configura-se como crime ambiental pelo potencial poluidor dos resíduos. Portanto, a gestão do lodo bruto é uma tarefa relevante pelos riscos epidemiológicos e a ocorrência de metais pesados. A utilização de técnicas de estabilização/solidificação é um meio de permitir o tratamento de resíduos. Este trabalho teve como objetivo monitorar o impacto ambiental causado pela utilização de resíduos do lodo em base e sub-base de pavimentos, por meio da construção de um modelo reduzido, das misturas de solo + lodo + estabilizante, para o lodo de ETE e para o lodo de ETA. Foram analisados durante um ano parâmetros como umidade, pH, recalque e concentração de metais. Os resultados apontaram que o uso do processo de estabilização/solidificação com os resíduos de lodo para fins de pavimentação é uma solução que pode equacionar problemas ambientais e econômicos.

Authors: Alcantar González Blanca Viridiana , Trujillo Xóchitl , Huerta Miguel
Published: September 2017

Durante el ejercicio, los requerimientos de glucosa por los tejidos se incrementan, particularmente en el músculo esquelético; durante el ejercicio de intensidad moderada (60-75% VO2máx); el incremento de glucosa es debido a un aumento en la relación glucagon venoso-insulina (Engler 2006). En el presente trabajo se determinó el efecto del ejercicio de resistencia aeróbica durante cuatro semanas sobre el peso corporal y los niveles de glucosa sanguínea en ratas Wistar. Los animales recibieron entrenamiento en una banda sinfín (Modular Enclosed Treadmill; Columbus Instrument, Columbus, OH, USA), cero grados de inclinación, con incorporación de dispositivo eléctrico de 10 mV. El protocolo de marcha se aplicó en sesiones de 30 min/día, a una velocidad de 10 m/min con una frecuencia de 5 veces/semana durante 4 semanas.  Se midió el peso corporal y la glucosa sanguínea. Se determinó la Curva de Tolerancia Oral a la Glucosa (CTOG) en sangre en ayuno de 12 horas al inicio y al fin de cuatro semanas de ejercicio. La diferencia entre los grupos se analizó mediante la prueba estadística t de Student para comparación de medias, considerando una p≤0.05 como significativa. Después de cuatro semanas de entrenamiento, los grupos no mostraron diferencias significativas en el peso corporal 262.0±31.78 g al inicio y 292.01±35.62 g al final en el grupo control (p>0.05) vs. 282.75±25.91 g al inicio y 301.47±31.38 al final en el grupo de ratas entrenadas (p>0.05). Asimismo, los niveles de glucosa sanguínea antes y después del protocolo de ejercicio no se modificaron significativamente entre los grupos de estudio, siendo en el grupo control de 73.5±3.8 g/dL al inicio y 83.5±2.38 g/dL después de las 4 semanas de estudio; mientras que en el grupo experimental el nivel de glucosa sanguíneo disminuyó de 91.0±7.43 g/dL al inicio a 85.7±7.0 g/dL al final de las 4 semanas del protocolo de entrenamiento; sin embargo, esta diferencia no fue significativa entre los grupos (p>0.05). La CTOG antes y después del protocolo de ejercicio tendió a ser similar en ambos grupos de estudio.

An Asset Allocation Model and Its Solving Method
Authors: Zhang Qingye , Gao Yan
Published: September 2017

Asset allocation is an important issue in finance, and both risk and return are its fundamental ingredients. Rather than the return, the measure of the risk is complicated and of controversy. In this paper, we propose an appropriate risk measure which is precisely a convex combination of mean semi-deviation and conditional value-at-risk. Based on this risk measure, investors can trade-off flexibly between the volatility and the loss to tackle the incurring risk by choosing different convex coefficients. As the presented risk measure contains nonsmooth term, the asset allocation model based on it is nonsmooth. To employ traditional gradient algorithms, we develop a uniform smooth approximation of the plus function and convert the model into a smooth one. Finally, an illustrative empirical study is given. The results indicate that investors can control risk efficiently by adjusting the convex coefficient and the confidence level simultaneously according to their perceptions. Moreover, the effectiveness of the smoothing function proposed in the paper is verified.
Performance Analysis of a Discrete-Time Queue with Working Breakdowns and Searching for the Optimum Service Rate in Working Breakdown Period
Authors: Lan Shaojun , Tang Yinghui
Published: September 2017

This paper deals with a discrete-time Geo/Geo/1 queueing system with working breakdowns in which customers arrive at the system in variable input rates according to the states of the server. The server may be subject to breakdowns at random when it is in operation. As soon as the server fails, a repair process immediately begins. During the repair period, the defective server still provides service for the waiting customers at a lower service rate rather than completely stopping service. We analyze the stability condition for the considered system. Using the probability generating function technique, we obtain the probability generating function of the steady-state queue size distribution. Also, various important performance measures are derived explicitly. Furthermore, some numerical results are provided to carry out the sensitivity analysis so as to illustrate the effect of different parameters on the system performance measures. Finally, an operating cost function is formulated to model a computer system and the parabolic method is employed to numerically find the optimum service rate in working breakdown period.

Published: September 2017

In this paper, we investigate the disparities of China’s insurance market from the viewpoint of geography and enterprise by using the monthly data from January 2006 to December 2015. We divide the whole insurance market into two parts, namely property insurance and personal insurance. By constructing and analyzing minimum spanning trees of insurance market, we obtain the results as follows: (i) The connections between provinces are much closer than those of firms, and there are regional links between neighboring provinces in the minimum spanning tree (MST); and (ii) the domestic funded firms and foreign funded firms form two explicit clusters in the MSTs of property and personal insurance market.
Effect of Water Salinity and Water–Filled Pore Volume on High–Frequency Dielectric Measurements in Porous Media
Authors: Chen Huangye , Heidari Zoya
Published: September 2017

High-frequency dielectric measurements have been attractive candidates for assessment of water-filled porosity in porous media. In the presence of saline water, the water molecules lose their orientation freedom partially because of hydration with ions and make these measurements sensitive to water salinity, which makes the interpretation of the dielectric-permittivity measurements challenging. The effects of water salinity on the real and the imaginary parts of dielectric permittivity have not yet been quantitatively studied in high-frequency (e.g., greater than 1 GHz) measurements. We measured dielectric permittivity of brine at frequencies ranging from 1 MHz to 3 GHz at room temperature and pressure conditions, where water salinity varies between 0 and 160 kiloparts per million (kppm). We also measured the dielectric permittivity of rock samples with different brine saturations. Our experimental results confirmed that there exists a critical frequency above which water salinity does not affect the real part of the dielectric constant, and such critical frequency increases as water-filled porosity and water salinity increase. At high frequencies where the real part of the dielectric constant is independent of the frequency, there exists a critical water-filled porosity below which water salinity has negligible effect on the real part of the dielectric constant. However, when water-filled porosity is higher than this critical value, the real part of the dielectric constant slightly decreases by increasing water salinity. Further, the results showed that at frequencies greater than the critical frequency, there is a critical water salinity below which the imaginary part of the dielectric constant increases as the water salinity increases, whereas the imaginary part of the dielectric constant decreases if the water salinity exceeds the critical value. The quantitative results on the effect of water salinity on dielectric measurements can potentially improve interpretation of dielectric-permittivity measurements for reliable assessment of water-filled porosity and hydrocarbon saturation.

Published: September 2017

Quality management systems in public organizations influence the quality of service delivery outputs. The purpose of this study was to determine the quality of service delivery at Community Service Centres (CSC) of the South African Police Service (SAPS) in the Western Cape, South Africa. A mixed-method research approach was employed to gather data for the study. Both a survey questionnaire and in-depth interviews were used to collect the data. The sample data set contacted 300 respondents from three policing areas situated in the Western Cape Metropolis. The main findings indicated that clients were satisfied with the level of service they received from the SAPS. However, the main area of concern was the absence of service delivery initatives at three police stations.

El maíz (Zea mays L.) es uno de los cereales con mayor superficie sembrada a nivel mundial, debido a su importancia en la alimentación humana y animal. Son muchos los agentes etiológicos que ocasionan enfermedades en la plantas de maíz; sin embargo,                Fusarium verticillioides (Sacc.) Nirenberg, es uno de los mohos a los cuales se le ha prestado especial atención por su amplia distribución, especialmente en zonas tropicales y subtropicales, su  capacidad toxigénica y su resistencia. Por tal motivo, se evaluó la incidencia de F. verticillioides y el contenido de fumonisinas en granos de maíz blanco de once híbridos destinados al consumo humano provenientes de los estados Guárico y Yaracuy, Venezuela. Método: La cuantificación de especies toxigénicas se realizó por siembra directa de granos enteros y desinfectados con NaClO al 3,27%, sobre el medio malta sal agar, expresando los resultados como porcentajes de granos colonizados por mohos totales y por especies potencialmente toxigénicas. El contenido de fumonisinas se cuantificó por el método inmunoquímico con columnas de inmunoafinidad para fumonisinas (B1+B2).                      Resultados: No se observaron diferencias estadísticas significativas para la incidencia de F. verticillioides y la concentración de fumonisinas en las muestras evaluadas en ambos estados. La micobiota asociada a los granos de maíz fueron Aspergillus flavus, Aspergillus Niger, A. ochraceus,  A. terreus, Eurotium chevalieri, F. verticillioides, Penicillium spp. Alternaria sp., y Curvularia sp. La  mayor incidencia promedio de mohos toxigénicos la obtuvieron A. flavus (24,3%), F. verticillioides (14,6%) y Penicillium sp. (4,4%) en Yaracuy; no obstante, en Guárico fueron F. verticillioides (16,7%) y Penicillium spp. (13,8%). La concentración promedio de fumonisinas en Yaracuy y Guárico fue de 1,8 y 8,4µg/g, respectivamente, superando el límite permitido para consumo humano (1 µg/g).Discusión: Con base en la baja incidencia de F. verticillioides y los bajos contenidos de fumonisinas detectados en los híbridos D1B-348 (proveniente de Guárico) y D1B-246 (proveniente de Yaracuy), se recomienda su uso en los respectivos estados, como medida de control del patógeno a nivel de campo y evitar la posible contaminación con fumonisinas.
