    The genetic resources in family farms are the result of a dynamic evolutionary process. The objectives of this study were to characterize local varieties for resistance to major foliar diseases and Diabrotica speciosa insect damage and evaluate the action of homeopathic preparations in organic production of Phaseolus vulgaris L. The characterization study of local varieties of Phaseolus vulgaris L. was held in three locations: (a) Experimental Station Epagri in Lages; (B) family farm property in Sao Jose do Cerrito and (c) in Anita Garibaldi. The experimental design was a randomized block design with four replications. The ten Phaseolus vulgaris L. accesses called: Capixaba, Carioquinha 1, Carioquinha 2, Pet, Black 1, 2 Black, Pink, Tibagi, Uirapurú, and Red characterized as Creoles. The attributes were obtained from: thousand kernel weight (PMG) in grams, number of pods per plot (NVP), and yield in kg ha-1. There were five reviews to estimate incidence and severity (a) Anthracnose (Coletotrichum lindemuthianum) (b) or bacterial blight bacterial blight (Xanthomonas axonopodis pv. Phaseoli), (c) angular Mancha (Pseudocercospora griseola) and (d) Virus the Golden Mosaic Bean (Bean Golden Mosaic Virus) in 10 plants of central rows of the plot. The infestation cows (Diabrotica speciosa) was evaluated by counting insects. The use of homeopathy in control disease bean field was carried out in two locations: Experimental Station of Lages (a) and Campos Novos (b). The experimental design was a completely randomized design with four replications in a factorial scheme 4x3 (prepared x cultivars). The homeopathic consisted without application, prepared homeopathic of Bordeaux mixture and diatomaceous earth, homeopathic preparation of Phosphorus and pH Silicea land, obtained in 30CH (Proximate Hahnemann). The applications of were weekly. The three cultivars were IPRCrow, IPR-Uirapuru and IPR-Tiziu. Five evaluations to estimate incidence and severity were performed: (a) bacterial blight and (b) anthracnose and insect pest Diabrotica speciosa during the crop cycle. After harvest were obtained results of anthracnose in the pods, number of pods per plant, number of seeds per pod, thousand seed weight and yield per hectare. The analysis was performed according to the experimental design, using the F test (variance analysis), and comparisons were performed using Tukey test at 5% using the statistical environment R. version 3.0.3. The study results of the characterization of landraces indicated that there were significant interactions between the local and the varieties (hits). To the location in Sao Jose do Cerrito, the highest average yield in kg ha-1 were obtained, the Pet varieties, Black 2 and Uirapuru showed the highest absolute values, but not differing varieties of Tibagi, Black 1, Rose and Capixaba. For the weight of thousand grains the Red variety was the one with the largest absolute weight in grams. In the study of the occurrence and progress of the disease, was significant for the three sites in São José do Cerrito for the occurrence of anthracnose, the Red varieties, Capixaba and Carioquinha 2 showed lower susceptibility, but not statistically differ from the others. For instance bacteriosis no significant differences among varieties and locations. As for angular leaf spot, just for the town of Lages the Red varieties stood out were not statistically different from the others. To study the use of homeopathic preparations in the phytosanitary control of bean, the results showed that the grain yield in Campos Novos not significantly different than the treatments already in Lages all homeopathic preparations have levels above the free application, and the prepared Silicea land had the highest absolute value not statistically different from the others. The results of the occurrence of pods with anthracnosewere differentiated by cultivars in Campos Novos, with the cultivar IPR-Gralha that achieved the best results, with the lower susceptibility of anthracnose in the pods. For the number of pods per plant in Campos Novos the homeopathic preparation Phosphorus showed the highest absolute values. For the thousand seed weight were no significant differences between the trained and treatment without application. As the occurrence and progress of the disease, the result of the incidence of bacterial blight was significant for all homeopathic preparations in Campos Novos in relation to the application without being to cultivate IPR-Crow and prepared which had the lowest absolute values. In the incidence of anthracnose in Lages all homeopathic preparations were superior to no application. Regarding the severity of the diseases (bacterial blight and anthracnose) it was higher in Campos Novos during the evaluation period, the lower absolute values were observed for Phosphorus prepared for Campos Novos and to Lages. With regard to the occurrence of insect pest Diabrotica speciosa, all homeopathic provided lower insect occurrence than without applicationOs recursos genéticos existentes nas propriedades agrícolas familiares são resultado de um dinâmico processo evolutivo de conservação e uso. Os objetivos deste estudo foram caracterizar variedades crioulas quanto à resistência às principais doenças foliares e aos danos do inseto Diabrotica speciosa e avaliar a ação de preparados homeopáticos na produção orgânica de Phaseolus vulgaris L. O estudo de caracterização de variedades crioulas do Phaseolus vulgaris L. foi realizado em três locais: (a) Estação Experimental da Epagri em Lages; (b) Propriedade agrícola familiar em São José do Cerrito e (c) em Anita Garibaldi. O delineamento experimental foi o de blocos ao acaso com quatro repetições. Os acessos crioulos de Phaseolus vulgaris L. denominados de: Capixaba, Carioquinha 1, Carioquinha 2, Predileto, Preto 1, Preto 2, Rosa, Tibagi, Uirapuru, e Vermelho foram caracterizados em seus atributos de peso de mil grãos, número de vagens e rendimento. Foram realizadas cinco avaliações para estimativa de incidência e severidade das doenças (a) Antracnose (Coletotrichum lindemuthianum) (b) Bacteriose ou crestamento bacteriano comum (Xanthomonas axonopodis pv. phaseoli), (c) Mancha angular (Pseudocercospora griseola) e (d) Vírus do Mosaico Dourado do Feijoeiro (Bean Golden Mosaic Virus). A infestação de vaquinhas (Diabrotica speciosa) foi avaliada pela contagem de insetos. O uso da homeopatia no manejo fitossanitário do feijoeiro foi realizado a campo em dois locais: Estação experimental de Lages (a) e Campos Novos (b). O delineamento experimental foi de blocos inteiramente casualizados com quatro repetições, em esquema de fatorial 4x3 (preparados x cultivares). Os preparados homeopáticos constaram sem aplicação, Preparado homeopático de calda bordalesa e terra de diatomáceas, preparado homeopático de Phosphorus e de Silicea terra, obtidos na 30CH centesimal hahnemanniana. As aplicações dos foram semanais. As três cultivares utilizadas foram IPRGralha, IPR-Uirapuru e IPR-Tiziu. Foram realizadas cinco avaliações para a estimativa de incidência e severidade das doenças: (a) Bacteriose e (b) Antracnose e do inseto praga Diabrotica speciosa durante o ciclo da cultura. Após a colheita foram obtidos resultados de antracnose nas vagens, número de vagens por planta, número de grãos por vagem, peso de mil sementes e produtividade por hectare. A análise dos resultados foi realizada de acordo com o delineamento experimental, e comparações foram pelo teste Tukey a 5%, por meio do ambiente estatístico R. versão 3.0.3. Os resultados do estudo da caracterização de variedades crioulas indicaram que ocorreram interações significativas entre o local e as variedades (acessos). Para o local em São José do Cerrito, foram obtidos as maiores médias de produtividade em kg ha-1, as variedades Predileto, Preto 2 e Uirapuru apresentaram os maiores valores absolutos, não diferindo porém das variedades Tibagi, Preto 1, Rosa e Capixaba. Para o peso de mil grãos a variedade Vermelho foi a que apresentou o maior peso absoluto em gramas. No estudo da ocorrência e progresso das doenças, foi significativo para os três locais, em São José do Cerrito para a ocorrência de antracnose, as variedades Vermelho, Capixaba e Carioquinha 2 apresentaram menor suscetibilidade, porém sem diferirem estatisticamente das outras. Para a ocorrência de bacteriose não houve diferenças significativas entre as variedades e locais. Já para mancha angular, apenas para a localidade de Lages a variedades Vermelho destacou-se não diferindo estatisticamente das demais. Para o estudo do uso de preparados homeopáticos no controle fitossanitário do feijoeiro, os resultados demonstraram que os rendimentos de grãos em Campos Novos não apresentaram diferenças significativas com relação aos tratamentos, já em Lages todos os preparados homeopáticos apresentaram valores superiores ao sem aplicação, sendo o preparado Silicea terra apresentou o maior valor absoluto não diferindo estatisticamente dos demais. Os resultados da ocorrência de vagens com antracnose foram diferenciados pelas cultivares em Campos Novos, sendo a cultivar IPR-Gralha que obteve os melhores resultados, apresentando a menor suscetibilidade de antracnose nas vagens. Para o número de vagens por planta em Campos Novos o preparado homeopático Phosphorus apresentou os maiores valores absolutos. Para o peso de mil sementes houve diferenças significativas entre os preparados e o tratamento sem aplicação. A cultivar IPR-Gralha com o preparado Calda bordalesa + Terra de diatomáceas apresentaram os menores valores absolutos. Quanto à incidência de antracnose em Lages todos os preparados homeopáticos foram superiores ao sem aplicação. Com relação à ocorrência do inseto praga Diabrotica speciosa, todos os preparados homeopáticos proporcionaram menor ocorrência do inseto do que o sem aplicaçãoCoordenação de Aperfeiçoamento de Pessoal de Nível Superio

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

    Author Under Sail The Imagination of Jack London, 1893-1902

    No full text
    In Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
