The influence of light on the partition of photoassimilates in Canavalia ensiformis (L.) DC
No full textA determinação do funcionamento da relação fonte-dreno pode otimizar o processo de produção das culturas agrícolas. No entanto, até o momento, não se sabe como a luz modula os mecanismos de sinalização na relação fonte-dreno entre raiz e parte área. Neste contexto, utilizou-se Canavalia ensiformis (L.) DC com o objetivo de verificar a interação entre os órgãos da planta em resposta à luz. Para isso, a retirada dos órgãos fonte (cotilédones ou folhas) de plantas crescidas na luz e escuro possibilitou avaliar a importância destes para a alocação de fotoassimilados. Sob as mesmas condições, a enxertia foi utilizada para avaliar a sinalização entre parte aérea e raiz. Os resultados comprovaram que no escuro o hipocótilo foi forte dreno em todos os tratamentos. Na ausência das folhas, ocorreu o acúmulo de biomassa na raiz, porém este efeito ocorreu somente nas plantas cultivadas em condição de luz. A enxertia permitiu verificar a importância dos sistemas radicular e parte aérea na partição de fotoassimilados, revelando que a luz é um sinal que torna os órgãos raiz e folhas fortes drenos, dependendo da condição ambiental em que as plantas são aclimatadas. No entanto, a iluminação direta das raíz de C. ensifomis (L.) DC não altera a morfometria e incremento de biomassa da raiz e dos órgãos da parte áreaDetermining the functioning of the source-sink relationship can optimize the production process of agricultural crops. However, so far, it is not known how the light mudulates the signaling mechanisms in the source-sink relationship between root and shoot. In this context, Canavalia ensiformis (L.) DC was used in order to verify an interaction between plant organs in response to light. For this, the removal of source organs (cotyledons or leaves) from plants grown in light and dark allowed us to assess their importance for a alocation of photoassimilates. Under the same conditions, grafting was used to assess the signaling between shoot and root. The results showed that in the dark the hypocotyl was a strong drain in all treatments. In the absence of leaves, there was an accumulation of biomass in the root, but this effect only occurred in plants grown under light conditions. The grafting changes verify the importance of the root and shoot systems in the partition of photoassimilates, revealing that light is a sign that makes the root organs and leaves strong drains, depending on the environmental condition in which the plants are acclimated. However, direct illumination of the roots of C. ensifomis (L.) DC does not change the morphometry and increment of root and organ biomass in the area
Educação do Campo na Amazônia: novos olhares e antigas questões do projeto político pedagógico
Get PDFABSTRACT. The rural schools, in the state of Para, have an educational proposal that seeks to offer quality education, considering the specificities of the rural reality. To this end, the Political Pedagogical Project (PPP) is essential to define several elements of the educational process. However, some teaching units consider the document to be a mere legal requirement. In this context, the objective of this study was to analyze the PPP of a municipal school, located in the surroundings of a conservation unit in the Brazilian Amazon, in Sao Caetano de Odivelas, seeking to understand the strategies proposed to articulate the development of teaching, in the context of the local reality. The research adopted the qualitative method, with bibliographical and documental support and was carried out in the period from October 2022 to March 2023. Among the results, it is noteworthy that the PPP has limitations and is not an appropriate document to guide the actions and school practices. Among the limitations is the absence of the peculiarities related to the way of life, work, territory and territoriality of the people and populations of the Mocapajuba Marine Extractive Reserve.ABSTRACT.

RESUMEN. Las escuelas rurales, en el estado de Pará, tiene una propuesta educativa que busca ofrecer educación de calidad, considerando las especificidades de la realidad del campo. Por lo tanto, el Proyecto Político Pedagógico (PPP) es esencial para definir diversos elementos del proceso educativo. Sin embargo, algunas unidades de enseñanza consideran el documento como un mero requisito legal. En este contexto, el objetivo de este estudio fue analizar el PPP de una escuela municipal, ubicada en el entorno de una unidad de conservación de la Amazonia brasileña, en São Caetano de Odivelas, buscando comprender las estrategias propuestas para articular el desarrollo de la educación en el contexto de la realidad local. La investigación adoptó el método cualitativo, con apoyo bibliográfico y documental y fue realizada en el período de 3octubre de 2022 a marzo de 2023. Entre los resultados, se destaca que el PPP tiene limitaciones y no es un documento adecuado para orientar las acciones y prácticas escolares. Entre las limitaciones está la ausencia de peculiaridades relacionadas con el modo de vida, trabajo, territorio y territorialidad de los pueblos y poblaciones de la Reserva Extractiva Marina de Mocapajuba.ABSTRACT.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
No full textWe 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
