Authors: Крыканов Дмитрий Дмитриевич
Published: December 2017

В статье изучены актуальные проблемы составления методологии оценки проектов государственно частного партнерства в России и за рубежом. Оценка эффективности проектов до сих пор остается спорным моментом в мировой практике ГЧП, так как основные подходы противоречивы и взаимоисключаемы. Рассмотрены основные аспекты анализа – количественный и качественный методы, оценка по методу «издержки-выгоды», а также рассмотрены основные способы анализа финансовой модели проекта. Приведенные методы апробированы в конце статьи на примере отечественного проекта государственно-частного партнерства «западный скоростной диаметр» в городе Санкт-Петербург. В заключении на основе полученных результатов приведены рекомендации для министерства экономического развития РФ.
How institutional voids influence Brazilian foreign direct investment in Angola
Authors: Virches Renato , Cahen Fernanda Ribeiro
Published: December 2017

How do institutional voids influence emerging market multinationals (EMNEs) foreign direct investment (FDI) in developing countries? In this article we respond to this question by examining Brazilian FDI in Angola as our analytical setting. We focus on the host country’s institutions and its institutional voids as essential factors that attract the FDI of EMNES to developing countries. The research indicates that Brazilian companies fill in much of these voids within the market intermediaries, often creating a point of competitive advantage, and also creating advantages in relation to FDI from other economies that invest in Angola. The scarce literature on FDI in Africa has been largely dedicated to the analysis of Chinese investment in the region. We aim to complement recent research on the influence of the host country’s institutions on the behavior of FDI in developing countries, explaining how some EMNEs are able to use the institutional voids of developing countries as market opportunities. Our findings should provide also implications for EMNEs managers from other emerging markets by providing a better understanding of how Brazilian multinationals expand their business in less developed countries, handle institutional voids and manage relationships with local and foreign institutions in the host country.
PRINCÍPIOS DA SUSTENTABILIDADE NO PLANEJAMENTO SOCIOAMBIENTAL DO COMITÊ ECOS DE PERNAMBUCO
Authors: Silva Leonio José Alves da , El-Deir Soraya Giovanetti , Silva Rebecca Guerra da
Published: December 2017

A sustentabilidade possui Princípios que podem ser norteadores para a gestão, tanto na esfera pública quanto privada. Quando da realização do planejamento institucional, tais princípios auxiliam para que se alcance uma eficiência socioambiental. O presente trabalho analisou a aderência do planejamento estratégico/tático socioambiental do Comitê Ecos de Pernambuco aos Princípios de Sustentabilidade definidos por Rohde (1995), buscando compreender o grau de proximidade e distanciamento entre estes. Inicialmente, foi estabelecido um domínio teórico conceitual a respeito do Planejamento, visando elevar o grau de entendimento sobre as questões relativas ao tema central desta pesquisa, mediante o levantamento dos dados secundários. Posteriormente, buscou-se compreender se os temas e os eixos deste planejamento tinham uma visão integralista ou fracionada da realidade, identificando os pontos de interação ou distanciamento entre estes com os Princípios de Sustentabilidade, mediante análise qualiquantitativa. A relação presente no planejamento estratégico/tático socioambiental do referido Comitê entre temas, eixos norteadores e os Princípios, denota a sustentabilidade das ações envolvidas. Os resultados indicam que, embora haja oscilação quanto ao grau de proximidade e distanciamento entre os elementos abordados, conclui-se que a sustentabilidade está presente no planejamento do Comitê, demonstrando que o Poder Público local está em alinhamento com as demandas do novo paradigma socioambiental.

Published: December 2017

Resumen: El dengue es una infección vírica transmitida por la picadura de las hembras infectadas de mosquitos del género Aedes aegypti que se presenta en los climas tropicales y subtropicales de todo el planeta, sobre todo durante la estación lluviosa. Según el Ministerio de Salud de la Nación, en 2016 Argentina se enfrentó al peor brote epidémico de dengue desde 2009. El nordeste argentino es la zona más afectada por casos de dengue, dado que allí se produce una combinación de altas temperaturas con una humedad también elevada. La provincia de Corrientes, además, por su situación geográfica tiene un alto nivel de vulnerabilidad a la presencia del mosquito portador del virus. El presente artículo muestra los resultados del análisis de contenido de la cuenta oficial de Twitter @saludcorrientes, desde el 1 de enero hasta el 30 de abril de 2016 sobre el fenómeno que nos ocupa, teniendo en cuenta que, en la era digital, las redes sociales son un instrumento clave para informar a la población sobre cualquier emergencia sanitaria. Se puede afirmar que, al haber emitido tan solo 54 tweets en el mencionado periodo, el Ministerio de Salud de la Provincia de Corrientes utilizó escasamente las redes sociales para la prevención de la enfermedad y promoción de la salud.Palabras clave: Comunicación de Crisis, Dengue, Redes Sociales, Twitter, Argentina, Provincia de Corrientes, Prevención, Salud.Abstract: Dengue is a viral infection transmitted by the bite of infected females of mosquitoes of the genus Aedes aegypti that occurs in tropical and subtropical climates throughout the planet, especially during the rainy season. According to the Ministry of Health of the Nation, in 2016 Argentina faced the worst epidemic outbreak of dengue since 2009. The northeast of Argentina is the area most affected by cases of dengue, given a combination of high temperatures and humidity. The province of Corrientes, also, due to its geographical situation, has a high level of vulnerability to the presence of the virus-carrying mosquito. This article shows the results of content analysis of the official Twitter account @saludcorrientes, from January 1 to April 30, 2016 in regards to the phenomenon. The study takes into account that, in the digital era, social networks are a key instrument to inform the population about any health emergency. It can be said that, having issued only 54 tweets in the aforementioned period, the Ministry of Health of the Province of Corrientes used social networks sparingly for the prevention of disease and health promotion.Keywords: Crisis Communication, Dengue Fever, Social Media, Twitter, Argentina, Province of Corrientes, Prevention, Health.

Pedagogia palhacesca: a escola do só eu no ensino regular
Authors: Ferreira Frederico de Carvalho , Wuo Ana Elvira
Published: December 2017

O presente trabalho refere-se a uma reflexão crítica acerca das potencialidades transgressoras de uma pedagogia palhacesca, realizada numa escola da rede municipal de Uberlândia-MG. A partir da apropriação de uma poética ridente, de aspectos palhacescos e a inserção do palhaço como figura transgressora no âmbito escolar, no que tange a proposta de construção de uma escola risonha, foi possível perceber possibilidades, construir sonhos, subverter a lógica, poetizar momentos, descontruir o cartesianismo e eleger o riso como ritual de quebra de paradigmas na educação básica.

Para uma contra-história do espetáculo moderno. Primeiras notas sobre o teatro dos ciarlatani
Authors: Tessari Roberto , Santos Ivanildo Piccoli
Published: December 2017

Com base nos limitados documentos restantes, registrou-se um verdadeiro e próprio mercado moderno do espetáculo com os novos cerretani-ciarlatani, charlatães da praça, que assumiram o papel de terapeutas populares através de diversos recursos cênicos como as máscaras dos zanni. Esses ciarlatani-espetáculos constituíam uma estrutura para propiciar e explorar as expectativas do divertimento de um público não mais elitista, com um fim cômico - espetáculos de máscaras. Os ciarlatani tornam-se comediantes e se servem da comédia como meio eficaz para atrair a venda de suas mercadorias e deixam um imenso legado na história dos espetáculos de lugares públicos.

Ói Nóis e Companhia do Latão: a coragem de morar com a sogra ou memória, convívio e resistência na experiência de grupos de teatro brasileiros
Authors: Silva Carlos Eduardo da
Published: December 2017

O presente artigo aborda os grupos de teatro como os genros de uma sogra nada indesejável, Mnemôsine, a deusa da memória, por isso, são núcleos importantes da memória do Teatro Brasileiro, restaurada e enriquecida constantemente. O conceito de memória é observado não apenas como a trajetória artística dos coletivos, mas como um saber adquirido que conserva as diversas experiências vivenciadas pelos membros de um grupo, seu conhecimento prático e sua maneira peculiar de fazer teatro. Além disso, a memória é tomada como uma força dinâmica, adquirida e aperfeiçoada essencialmente pelo convívio no grupo, em razão do caráter comunitário da construção dos saberes e cuja potência dependente da estabilidade da formação do coletivo articulada com estratégias de registros documentais que possam ser transmitidos às gerações subsequentes e aos novos participantes, de modo a manter vivos os princípios éticos, ideológicos e estéticos das grupalidades. As reflexões foram possíveis através da análise das trajetórias do Ói Nóis Aqui Traveiz e da Companhia do Latão. Para tanto foram entrevistados atuantes artistas dos dois grupos. Por fim, observa-se como os grupos em questão enfrentam as pressões econômicas e políticas que são forças que tentam desagregar e destruir as memórias dessas organizações.
Saber sentido

A ruptura epistemológica que fez a ciência moderna existir deslegitimou os demais saberes. Esse ato epistemológico secular ainda desqualificou as artes que, por sua vez, na contemporaneidade, estão fortemente presentes em determinados territórios da ciência. O denominado pensamento racional, portanto, é também feito do exercício de sentir e de experimentar o mundo. Todo saber é sentido, na medida em que se sente-pensa para se fazer.
A participação da agricultura familiar no Programa Nacional de Alimentação Escolar: estudo de casos em municípios paulistas da região administrativa de Campinas
Authors: Marques Paulo Eduardo Moruzzi , Retière Morgane Isabelle Hélène , Almeida Nayla , Santos Carolina Ferraz dos
Published: December 2017

A participação da agricultura familiar no Programa Nacional de Alimentação Escolar (PNAE) constitui a questão chave deste artigo. Nesta perspectiva, nosso estudo se dirigiu à discussão sobre o funcionamento dos conselhos municipais de alimentação escolar (CAE) de Americana, Cosmópolis e Piracicaba. Trata-se de uma análise sobre as compras de produtos da agricultura familiar, interrogando em que medida o Programa Nacional de Alimentação Escolar é considerado como um meio para promover o desenvolvimento local com ênfase no fortalecimento dos agricultores familiares. O conceito de referencial de circuitos curtos de proximidade, vinculado à sustentabilidade agroalimentar, foi considerado em nossa análise. Foram entrevistados, em 2015 e 2016, atores chave do programa nos municípios escolhidos. Nossa pesquisa permitiu constatar que todas as prefeituras estudadas realizam compras de produtos da agricultura familiar. Porém, o fomento ao desenvolvimento local está longe de alcançar o que é recomendado nos documentos do PNAE.  Para atingir o mínimo de 30% dos recursos do Fundo Nacional de Desenvolvimento da Educação (FNDE) transferidos para os municípios para a aquisição de gêneros alimentícios advindos da agricultura familiar, as prefeituras consideradas recorrem frequentemente a organizações distantes de agricultores familiares.
O auxílio alimentação no Brasil: seu efeito na distribuição da renda e no Índice de Massa Corporal dos empregados, conforme dados da Pesquisa de Orçamentos Familiares de 2008-2009
Authors: Hoffmann Rodolfo , Santiago Letícia Alves Tadeu
Published: December 2017

Lei de 1976 criou o Programa de Alimentação do Trabalhador (PAT), dando incentivo fiscal às empresas que promovessem a alimentação de seus empregados. A regulamentação estabelece que isso pode ser feito mantendo serviço próprio de refeições ou, indiretamente, facilitando sua aquisição por meio de tíquetes ou cartões específicos. A Pesquisa de Orçamentos Familiares de 2008-2009 registrou a valor do Auxílio Alimentação como parte da remuneração dos empregados. Esses dados são utilizados para analisar como esse auxílio afeta a distribuição da renda no Brasil. Embora a lei que criou o auxílio considerasse que deveriam ser atendidos prioritariamente os trabalhadores de baixa renda, verifica-se que esse auxílio é um componente levemente regressivo da renda familiar per capita, beneficiando mais os trabalhadores relativamente bem remunerados. Também é analisado o efeito do auxílio alimentação sobre características antropométricas dos beneficiados. Controlando o efeito da renda, não foi possível detectar qualquer impacto do auxílio alimentação no Índice de Massa Corporal (IMC) ou na probabilidade de sobrepeso ou obesidade em homens. Mas há evidências de que, em algumas circunstâncias, o auxílio favorece a obesidade de mulheres.

Mesmo com avanços significativos em relação a políticas e programas no combate à miséria e à fome, Comunidades Remanescentes de Quilombo perpassam por disparidades envolvendo o Direito à alimentação, concretizando um desafio atingir parcelas mais vulneráveis da população. Assim, objetivou-se avaliar a prevalência de Insegurança Alimentar intradomiciliar em domicílios de uma comunidade quilombola de um município da Grande Aracaju-SE e seus aspectos associados. Com um total de 26 domicílios, totalizaram-se informações de 88 moradores em relação ao perfil socioeconômico, à insegurança alimentar intradomiciliar, ao acesso a programas sociais, entre outros. Os dados foram analisados descritivamente, a partir de frequências relativas e medidas de tendência central. Foi aplicado o teste de Qui-Quadrado nas associações entre insegurança alimentar e outras variáveis. A prevalência de Insegurança Alimentar Moderada ou Grave (IAMG) encontrada foi de 52,2%, também foram encontradas associações significativas entre a situação de IAMG com variáveis de acesso a serviços de saúde e saneamento básico. Conclui-se que a prevalência de insegurança alimentar na comunidade é bastante elevada, estando associada a condições precárias de saneamento básico, acesso deficiente a serviços de saúde e a políticas públicas, revelando condição de vulnerabilidade referente à garantia de segurança alimentar e nutricional e do direito humano à alimentação adequada.
Qualidade da alimentação escolar a partir da aquisição de produtos da agricultura familiar
Authors: Führ Aline Luiza , Triches Rozane Marcia
Published: December 2017

Este estudo buscou verificar qual a repercussão da aquisição de alimentos da agricultura familiar para a qualidade nutricional de refeições oferecidas pela alimentação escolar em dois municípios do estado do Paraná (município A e B). Foram utilizadas chamadas públicas, editais de licitação, prestações de contas e cardápios escolares referentes ao ano de 2013. Os cardápios foram avaliados quantitativamente, com auxílio do programa Avanutri®. Esta análise foi complementada com a análise dos mecanismos de compras. Os resultados foram organizados por meio de estatística descritiva com o Microsoft Excel® e Statistical Package for the Social Science. O município que realizou maior aquisição de produtos provenientes da agricultura familiar também efetuou maiores investimentos em frutas e vegetais; adquiriu maior variedade de alimentos e apresentou cardápios mais adequados em macronutrientes, alguns micronutrientes, fibras e energia. Em ambos os municípios não houve adequação dos valores de cálcio, magnésio e zinco. As chamadas públicas garantiram a oferta de maior percentual de alimentos recomendados em relação às licitações. Os resultados apresentados exprimem que a aquisição de alimentos da agricultura familiar permite o planejamento de um cardápio mais adequado, influenciando positivamente na qualidade do consumo alimentar dos escolares.

ABSTRAK

 

Dalam dunia profesionalisme, seorang guru dituntut untuk memiliki kemampuan verbal yang baik Namun jika proses pembelajaran hanya mengandalkan kemampuan verbal saja, maka akan muncul keterbatasan-keterbatasan. Perkembangan IPTEK ini seharusnya dapat dimanfaatkan  juga dalam  dunia  pendidikan,  salah satunya  untuk  memaksimalkan proses pembelajaran di dalam maupun diluar kelas melalui pembuatan media pembelajaran interaktif berbasis ICT (Information and Communication Technology). Sehingga, keterbatasan-keterbatasan yang dapat timbul dari proses pembelajaran yang hanya mengandalkan lisan saja dapat dihindari atau paling tidak dapat diminimalisir. Kegiatan pengabdi adalah memberikan pelatihan pembuatan media pembelajarn interaktif berbasis PowerPoint bagi guru-guru di Kecamatan Pulogadung.

 

ABSTRACTIn the world of professionalism, a teacher is required to have good verbal skills. But if the learning process only rely on verbal skills alone, it will appear the limitations. The development of science and technology should be able to be utilized also in the world of education, one of them is to maximize the learning process inside and outside the class through the making of interactive learning media based on ICT (Information and Communication Technology). Thus, the limitations that can arise from the learning process that only rely on oral can be avoided or at least can be minimized. The devotional activity is to provide training on making PowerPoint-based interactive learning media for teachers in Kecamatan Pulogadung.

ABSTRAK

 Pelaksanaan KKN di perdesaan, memberi peluang bagi masyarakat untuk memperoleh ketrampilan dalam rangka menambah penghasilan. Dengan adanya mahasiswa KKN memberi ketrampilan, maka masyarakat akan berpeluang mendapatkan ketrampilan secara gratis yang pada akhirnya dapat memperoleh peluang mecari penghasilan tambahan.

 Namun demikian tidak semua mahasiswa peserta KKN mempunyai ketrampilan yang dapat diberikan ke masyarakat berupa ketrampilan yang menghasilkan “sesuatu yang dapat dijual”. Oleh karena itu kegiatan ini memberi bekal kepada mahasiswa calon peserta KKN untuk menjadi trainers di tempat mereka ber KKN nanti.

 Melalui pelatihan TOT bagi mahasiswa calon peserta KKN UNJ yang dideseminasikan kepada para ibu-ibu di lokasi KKN maka diharapkan diperoleh alternatif menambah penghasilan, dengan mengikuti pelatihan tanpa mereka harus mengeluarkan biaya.

 

ABSTRACTImplementation of KKN in rural areas, provides an opportunity for the community to obtain skills in order to increase income. With the KKN students giving skills, then the community will have the opportunity to get the skills for free which in turn can get the opportunity to find additional income.However, not all students participating KKN have skills that can be given to the community in the form of skills that produce "something that can be sold". Therefore, this activity gives provision to students of KKN candidates to become trainers in their place of KKN later.Through TOT training for students of KKN UNJ candidates disseminated to the mothers in KKN location it is expected to obtain alternative income, by training without them have to spend.
Accelerator and Multiplier for Macroeconomic Processes with Memory
Authors: Tarasova Valentina V. , Tarasov Vasily E.
Published: December 2017

The paper proposes an approach to the description of macroeconomic phenomena, which takes into account the effects of fading memory. The standard notions of the accelerator and the multiplier are very limited, since the memory of economic agents is neglected. We consider the methods to describe the economic processes with memory, which is characterized by the fading of a power-law type. Using the mathematical tools of derivatives and integrals of non-integer orders, we suggest a generalization of the concept of the accelerator and multiplier. We derive the equations of the accelerator with memory and the multiplier with memory, which take into account the changes of endogenous and exogenous variables on a finite time interval. We prove the duality of the concepts of the multiplier with memory and the accelerator with memory. The proposed generalization includes the standard concepts of the accelerator and the multiplier as special cases. In addition these generalizations provide a range of intermediate characteristics to take into account the memory effects in macroeconomic models.
Persona & Parrhesia: Research notes on the dialectics of the real
Authors: Stocchetti Matteo
Published: December 2017

If reality is socially established through practices that, directly or indirectly, depend on communication and therefore on some notion of truth, the idea of a post-truth communicative regime or “age” may seem not only bizarre but also worrying. The dissolution of the real announced by the prophets of postmodernism in the form of either a “perfect crime” or a “liquid reality”, has been interpreted as the effect of the crisis of truth and legitimation that Jean-Françoise Lyotard referred to with his notions of ”performativity” and ”legitimation by force”. In this perspective, reality depends on truth and the possibility of truth depends in turn, by configurations of power that seem too elusive and ephemeral to be effectively engaged with in either theory or practice. In this paper, I mobilize the notions of parrhesia and persona in an effort to establish an alternative standpoint to discuss the epistemological and ontological implications of the postmodern condition and the crisis of truth associated to it. The main point can perhaps be summarized in the idea that, if the new regime of truth (or post-truth) relies on persona expressing the roles/characters compatible with it, the notion of parrhesia may gain a critical relevance for the normative evaluation of these personas and the social implications of their truth. Famously re-introduced by Michel Foucault in his analysis of truth and its discursive conditions, the notion of parrhesia has a heuristic potential that is not fully exploited. While challenging in fundamental ways the social construction of reality on practical grounds, the digitalization of social life presents also theoretical challenges some of which can be addressed by the reconceptualization of parrhesia in relation to the social role of the persona rather than the individual. In my paper, I present some preliminary research notes in this direction.
Resistance to Phytophthora Species among Rootstocks for Cultivated Prunus Species
Authors: Browne Gregory T.
Published: December 2017

Many species of Phytophthora de Bary are important pathogens of cultivated Prunus L. species worldwide, often invading the trees via their rootstocks. In a series of greenhouse trials, resistance to Phytophthora was tested in new and standard rootstocks for cultivated stone fruits, including almond. Successive sets of the rootstocks, propagated as hardwood cuttings or via micropropagation, were transplanted into either noninfested potting soil or potting soil infested with Phytophthora cactorum (Lebert & Cohn) J. Schöt., Phytophthora citricola Sawada, Phytophthora megasperma Drechs, or Phytophthora niederhauserii Z.G. Abad & J.A. Abad. Soil flooding was included in all trials to facilitate pathogen infection. In some trials, soil flooding treatments were varied to examine their effects on the rootstocks in both the absence and presence of Phytophthora. Two to 3 months after transplanting, resistance to the pathogens was assessed based on the severity of root and crown rot. ‘Hansen 536’ was consistently more susceptible than ‘Lovell’, ‘Nemaguard’, ‘Atlas’, ‘Viking’, ‘Citation’, and ‘Marianna 2624’ to root and/or crown rot caused by P. cactorum, P. citricola, and P. megasperma. By contrast, susceptibility to P. niederhauserii was similarly high among all eight tested genotypes of peach, four genotypes of peach × almond, two genotypes of (almond × peach) × peach, and one genotype of plum × almond. Most plum hybrids were highly and consistently resistant to crown rot caused by P. niederhauserii, but only ‘Marianna 2624’ was highly resistant to both crown and root rot caused by all of the Phytophthora species. The results indicate that there is a broad tendency for susceptibility of peach × almond rootstocks and a broad tendency for resistance of plum hybrid rootstocks to multiple species of Phytophthora.
Perpetual Flowering in Strawberry Species

Published: December 2017

The genetic control of flowering habit in many species of Fragaria has not been well studied. Identification of flowering traits and patterns for these taxa could be used in the quest for perpetual flowering (PF) genes and for the octoploids, broaden the genepool of available PF parents for breeding programs. As such, clones from the Fragaria germplasm collection housed at the USDA-ARS National Clonal Germplasm Repository in Corvallis, OR, were evaluated to describe flowering habits in various taxa and identify PF clones. Flower presence was recorded monthly for 962 clones of 36 taxa from the first of May through October in 2015 and 2016 to determine flowering habit and pairwise comparisons between taxa were examined using Pearson’s Chi-squared test. Taxa with the largest percent of PF accessions were F. vesca subsp. vesca f. semperflorens, F. vesca subsp. vesca f. alba, F. vesca subsp. americana, and F. virginiana subsp. glauca. These taxa had similar flowering habits to each other but were significantly different (α = 0.05) from most other taxa in which the seasonal flowering (SF) trait was predominant. Fifteen clones that demonstrated the PF phenotype in both 2015 and 2016 were identified. Differing genetic controls have been observed for flowering habit in F. ×ananassa and F. vesca. Additional studies are needed to determine genetic control of flowering in other Fragaria taxa.

Published: December 2017

Anthurium is native to habitats characterized by low nutrient supply; however, when cultivated, it demands a complete fertilization program. The objective of the present study was to determine the effect of varying proportions of anions [nitrate (NO3−), phosphate (H2PO4−), and sulphate (SO42−)] in the nutrient solution on the growth and nutrient status of container-grown anthurium. The effect of the anion proportion was modeled using mixture analysis. Plant growth increased when fertigated with solutions containing an anion proportion of 0.78:0.12:0.10, 0.20:0.12:0.68, and 0.80:0.02:0.18. The contour plots showed that optimum response may be achieved in two areas, an area with high NO3− proportion (0.50–0.80) and an area with high SO4−, provided H2PO4− was high (0.09–0.12 for H2PO4− and 0.55–0.70 for SO42−). The counter plots indicate that high SO42− proportions combined with low NO3− and H2PO4− were detrimental and that optimum growth depends not only on nitrogen (N) concentration, as it may be attained at either high or low NO3−. Nitrogen and sulfur (S) concentration was higher in plants fertigated with high NO3− (0.55–0.80) and SO42− (0.40–0.70) solutions. Shoot P was higher when plants were fertigated with solutions of low (as long as NO3− was at proportion of 0.50 and SO42− at 0.35) or high H2PO4− proportions (as long as SO42− proportion was at 0.35). At low concentration of S in the shoot, increasing S resulted in increasing shoot N; however, further S increments in the shoot were associated with a decrease in N. Plants fertigated with the highest proportion of H2PO4− resulted in the lowest S concentrations despite some solutions contained high SO42−, suggesting that H2PO4− counteracted the uptake of SO42−. Nitrogen and S were predominantly diverted to the roots in control plants; however, when plants were fed with both high SO42− and high H2PO4− solutions, even more S was allocated to the roots, which explains the increased shoot growth due to the lower S concentrations. In conclusion, the increased growth of anthurium was attained at either high or low NO3− proportion and it is able to cope with high SO42− by avoiding the transport of S to the shoot, decreasing SO42− intake, maintaining a favorable internal N/S and S/P proportion, and increasing P tissue concentration.

Selection of superior broccoli hybrids involves multiple considerations, including optimization of head quality traits. Quality assessment of broccoli heads is often confounded by relatively subjective human preferences for optimal appearance of heads. To assist the selection process, we assessed five candidate head quality indices that make use of a set of individual and distinct ratings for traits such as head color, head smoothness, bead size, bead uniformity, and others. The head quality indices were tested for both a) the ability to reduce interobserver rating variability and b) the ability to emphasize specific attributes that display the greatest associations with overall horticultural quality of heads. Index development was based on datasets generated from quality evaluations by three independent raters of two replicated variety trials in Spring 2014. Relative-importance analysis was used to identify specific traits most associated with overall quality. Developed models were subsequently tested and compared using data collected by three raters evaluating two similar trials in Spring 2015. Head smoothness, bead uniformity, head color, and holding ability were found to account for 78% of the model variation in overall head quality. Intraclass correlation coefficients (ICCs), which measure the degree of concordance among raters, were increased from 0.71 to 0.88 (P < 0.05) in one 2015 trial and from 0.67 to 0.80 (P < 0.05) in the second when comparing the simple overall quality assessment to the use of the index weighted by the most important individual head attributes. Thus, results showed that a quality index taking into account the relative importance of individual traits should enhance the identification of the best hybrids adapted to target conditions. This method can be used to improve concordance for subjective ratings in general.

Glyphosate is routinely used to eradicate existing turf in golf course fairway renovations. However, current label recommendations suggest delaying cultivation of glyphosate treated areas for 7 days. A 2-year field study was conducted to assess how various seedbed preparation techniques (i.e., verticutting, core-cultivation, or verticutting + core-cultivation) influence glyphosate efficacy on creeping bentgrass fairway turf when completed at various intervals shortly after application [0–7 days before cultivation (DBC)]. Percent green cover declined from initial values of ≈90% to ≤0.2% at the end of the study after glyphosate application at all timings, regardless of cultivation during both years. All cultivated plots had 37.9% to 72.3%, or 5.9% to 62.1% less green cover compared with noncultivated plots when glyphosate was applied ≤3 days before cultivation in 2014 and 2015, respectively. Generally, the number of days until green cover reached 1% (GC1) ranged from 6.6 to 11.1 in 2014 and 5.2 to 6.9 in 2015. Within glyphosate application timings, no differences in GC1 were observed between cultivated and noncultivated treatments in 2014, except at 0 DBC. The GC1 for verticutting was 5.1 days longer than noncultivated plots; however, all other cultivation treatments were equivalent to noncultivated plots when glyphosate was applied 0 DBC. All cultivation treatments reduced GC1 1.7 to 2.5 days compared with the no cultivation treatment, regardless of glyphosate application timing in 2015. Results from this study indicate that cultivation of creeping bentgrass fairway turf within 7 days of glyphosate application is not detrimental to long-term herbicide efficacy, and in some cases may actually enhance the rate of decline of glyphosate treated creeping bentgrass.

Grape (Vitis vinifera cv. Pok Dum) is a rich source of health relevant phenolic antioxidants and can be targeted to mitigate chronic oxidative stress commonly associated with noncommunicable chronic diseases (NCDs), such as cancer. Furthermore, improving health relevant phenolic bioactives and associated antioxidant properties of fruits by using chemical elicitation strategy has significant merit. Based on this biochemical rationale, chitosan and other chemical elicitors potassium dihydrogen phosphate (KH2PO4), potassium nitrate (KNO3), sodium selenite (Na2SeO3), and aluminum sulphate [Al2(SO4)3] were targeted to improve phenolic bioactive profiles and associated antioxidant and anticancer properties of cultured grape cells grown for 28 days. After chemical elicitor treatments, phenolic content, resveratrol content, antioxidant activity, phenylalanine ammonia-lyase (PAL) enzyme activity, and cytotoxicity (cell inhibition) against cancer cell lines of cultured grape cells were investigated using in vitro assay models. Overall, stimulation of phenolic bioactives and improvement in associated cytotoxicity against cancer cell lines were found in cultured grape cells after chemical elicitation treatments. Chitosan and other chemical elicitors resulted in lower growth of cultured grape cells; however, they enhanced phenolic biosynthesis on a cell weight basis when compared with the control. Chemical elicitor treatments, such as Na2SeO3 (50 mg·L−1 and 100 mg·L−1) and Al2(SO4)3 (50 mg·L−1), resulted in enhanced phenolic content at the end of 14 days of culture (1.7, 1.4, and 1.0-fold increase, respectively). Higher accumulation of resveratrol and higher antioxidant activity with Al2(SO4)3 (50 mg·L−1) and Na2SeO3 (100 mg·L−1) elicitation treatments were also observed. Enhanced phenolic bioactives in cultured grape cells in response to chemical elicitation treatment, such as Na2SeO3, also resulted in higher cytotoxicity against different cancer cell lines. Therefore, this study indicates that chemical elicitors, such as Na2SeO3 and Al2(SO4)3, as well as chitosan in select doses can be targeted to improve phenolic bioactives and associated antioxidant and anticancer properties in cultured grape cells and such strategy has relevance for wider applications with other phenolic antioxidant-enriched fruits.

High tunnels may help mitigate unfavorable climate and weather on lettuce (Lactuca sativa L.) production leading to greater yields and quality, yet information for using these systems in the Southeast region is lacking. This study evaluated the effect of high tunnels and three planting dates (PDs) (early March, late-March, and mid-April) on spring organic lettuce production. A 25% to 36% increase in marketable fresh weight for butterhead and romaine lettuce, respectively, was observed under high tunnels compared with the field in 2016, but there was no difference among the two growing systems in 2015. High tunnel lettuce was harvested ≈2 to 7 days earlier than in the field in 2015 and 2016, respectively. Pest and disease pressure (e.g., Sclerotinia sclerotiorum) as well as the incidence of physiological disorders (i.e., bolting, tip burn, and undersized heads) were similar between the two systems indicating that our high tunnel system did not provide a benefit for these issues. High tunnel air temperatures were ≈3 to 5 °C greater on the coldest mornings and only 1 °C greater on the warmest days compared with the field. Average relative humidity (RH), leaf wetness, and light levels were all lower under the high tunnels. Our results indicate that high tunnels can help increase the production of spring organic lettuce in Georgia, but that the advantage may depend on yearly weather conditions.

There is a lack of information related to adapting high tunnel systems to humid, subtropical climates in the Southeastern United States, resulting in a disadvantage for their use to extend growing seasons and meet the increasing demand for local horticulture products. This research project explored the possibility of growing organic broccoli and cauliflower (Brassica oleracea L.) under high tunnels during two consecutive fall/winter seasons in northeast Georgia (USDA plant hardiness zone 8a), particularly evaluating questions related to crop feasibility, planting dates and cultivar choices. Marketable yields for high tunnel broccoli ranged from ≈11,800 to 15,800 kg·ha−1 and were not consistently affected by either planting date or cultivar type. Broccoli required an additional 8–45 days to reach maturity compared with seed catalog estimates with harvesting occurring during mid-December to mid-January. Marketable yields for high tunnel cauliflower ranged from ≈8600 to 26,000 kg·ha−1 and were affected primarily by the cultivar type. Cauliflower required an additional 19–56 days to mature with harvesting occurring during the entire month of January. The first season was cooler than the second with the lowest growing degree days (GDD) units accumulated during the months of January and February. Differences in air temperature at the crop canopy between the high tunnel system and open field were largely related to high tunnel ventilation protocols that changed as the season progressed. An average heat gain of 7 to 8 °C under the high tunnels at crop canopy height was documented on the coldest days and an average of 1 °C gain on the warmest days compared with the open field. Overall, winter broccoli appeared more adaptable to high tunnels than cauliflower but production of both crops may be possible if planting dates and cultivar types are taken into account for the region.

There are generally inadequate supplies of seed for the newest rootstocks to satisfy the growing demand for the propagation material to be used in commercial citrus nurseries. Consequently, rootstock propagation, which is traditionally by seed, now often makes use of alternative methods such as cuttings and tissue culture (TC). Propagation through cuttings and TC will generate a root system that is largely composed of adventitious or lateral roots, compared with seed propagation, which will generally promote the formation of a well-defined taproot. In this study, we compared root architecture and growth of seven different rootstock plants, generated from seed, stem cuttings, or TC, during the early weeks of growth in the greenhouse. Based on total dry biomass, root mass fraction of plants generated from cuttings ranged from 11% to 16%, and from 16% to 29% and 21% to 30% for micropropagated plants and seedlings, respectively. Plants propagated through cuttings had the most primary roots (7–10), followed by tissue culture–propagated plants which developed an average of 2–6 primary roots. As expected, plants grown from seeds mostly developed a single and well-defined taproot during the first weeks. The total number of first order lateral roots was highest in the plants propagated as cuttings (108–185) compared with 53–103 and 43–78 for tissue culture–propagated plants and seedlings, respectively. Similarly, specific root length (SRL) was highest in plants derived from cuttings (21–43 m·g−1) and lowest in plants grown from seed (7–20 m·g−1). It is suggested that the larger number and length of roots on rootstock plants propagated through vegetative methods may be better suited for resource acquisition as compared with seed propagated plants.
