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
Produtividade, sazonalidade e análises tecnológicas de frutos de cultivares de mangueira em condições subtropicais
No full textA fruticultura permite ao produtor maiores rendimentos por unidade de área e assim destaca-se no cenário agrícola, sendo de suma importância o estudo da adaptação de diferentes cultivares de frutíferas aos locais de cultivo. Com o intuito de auxiliar e fortalecer a mangicultura paulista, através da avaliação da adaptação de cultivares, o objetivo deste trabalho foi avaliar a produtividade, sazonalidade e análises tecnológicas dos frutos das cultivares Palmer, Parwin, Tommy Atkins e Haden, enxertados sobre o porta-enxerto ‘Espada’ e conduzidas no espaçamento 5,0 m entre linhas e 4,5 m entre plantas (417 plantas.ha-1). O delineamento experimental utilizado foi o inteiramente casualizado, constando de 4 tratamentos (cultivares), 8 repetições e uma planta útil por repetição, com duas plantas bordadura. O presente trabalho foi realizado avaliando-se dois ciclos de produção: 2011/2012 e 2012/2013, na Fazenda Experimental São Manuel da Faculdade de Ciências Agronômicas da UNESP, Campus de Botucatu, localizada no município de São Manuel - SP. De acordo com os resultados obtidos é possível concluir que, a cultivar Parwin apresentou maior número médio de produtividade e produção, portanto pode ser indicada como opção de diversificação varietal para a região. As cultivares Haden e Tommy Atkins foram mais precoces e Palmer e Parwin mais tardias. Todas as cultivares avaliadas obtiveram elevado rendimento de polpa (>70%). Os frutos da cultivar Palmer apresentaram valores superiores de massa média e relação diâmetro longitudinal/diâmetro equatorial. Os frutos das cultivares Palmer (486,80N) e Parwin (337,08N) apresentaram valores superiores de firmeza. A cultivar Palmer apresentou, nos dois ciclos de avaliação...The fruit allows the producer to higher yields per unit area and thus stands in agricultural scenario, which is extremely important to study the adaptation of different cultivars to fruit cultivation sites. In order to support and strengthen mango São Paulo, through the evaluation of the adaptation of cultivars, the aim of this study was to evaluate yield, seasonality and technological advances of fruit cultivars Palmer, Parwin, Tommy Atkins and Haden, grafted on rootstock 'Sword' and conducted at 5,0 m spacing between rows and 4,5 m between plants (417 plants.ha-1). The experimental design was completely randomized, consisting of 4 treatments (cultivars), 8 replicates and one plant per replicate, with two plants surround. This study was conducted evaluating two cycles of production: 2011/2012 and 2012/2013 in São Manuel Experimental Farm of the Faculty of Agricultural Sciences, UNESP, Botucatu Campus, located in the municipality of San Manuel - SP. According to the results, we conclude that, to cultivate Parwin showed higher average productivity and output, so it can be displayed as varietal diversification option for the region. The cultivars Haden and Tommy Atkins and Palmer were earlier and the later Parwin. All cultivars had higher pulp yield (>70%). The fruits of cultivar Palmer showed higher values of average mass and relative longitudinal diameter / equatorial diameter. The fruits of cultivars Palmer (486,80 N) and Parwin (337,08 N) showed higher values of firmness. Cultivar Palmer presented in two evaluation cycles, higher content of vitamin C...

Application of pre-harvest calcium chloride in blackberry fruits 'Tupy'
No full textO experimento foi realizado na Fazenda Experimental São Manuel, da Faculdade de Ciências Agronômicas da UNESP, Campus de Botucatu (SP), nos anos de 2014 e 2015. Objetivou-se avaliar o efeito da aplicação pré-colheita de cloreto de cálcio (CaCl2) na qualidade de frutos da amoreira preta ‘Tupy’. Foram avaliadas plantas, cujas mudas foram plantadas em 23/06/2009. Conduziram-se seis hastes mais vigorosas, numa área experimental não irrigada, no sistema de espaldeira em T, com dois arames e com 1,2 metros de altura. O espaçamento foi de 0,6 m entre plantas e 4,0 m entrelinhas e a densidade de plantio de 4.166 plantas ha-1. No experimento o delineamento experimental adotado foi de blocos casualizados em fatorial 4 x 3, sendo o primeiro fator correspondente às concentrações de cloreto de cálcio (0; 1,5; 3 e 4,5 %) e o segundo aos números de aplicações (1, 2 e 3 aplicações). A fase fenológica adotada para a primeira aplicação do cloreto de cálcio foi dos frutos verdes em início de inchamento e ainda aderidos aos restos florais. Quando realizada mais de uma aplicação, havia um intervalo de cinco dias entre uma e outra. Foram realizadas avaliações físicas, físico-químicas, bioquímicas e enzimáticas nos frutos. Os níveis de Ca+2 foram aferidos nas folhas antes e após as aplicações com CaCl2 e nos frutos logo que realizada a colheita. A aplicação de CaCl2 em pré-colheita, na concentração de 4,5 %, quando os frutos estavam na fase fenológica de inchamento dos frutos com restos florais, promove menor perda de massa, maior firmeza e conteúdo de ácido ascórbico em amoras-pretas ‘Tupy’. Maiores concentrações de CaCl2 promovem decréscimo dos teores de açúcares solúveis redutores e totais, atividade antioxidante e polifenóis totais.The objective of this experiment was to evaluate the effect of pre-harvest application of calcium chloride (CaCl2) on 'Tupy' blackberry fruits, which was carried out at the São Manuel Experimental Farm, at the Faculty of Agronomic Sciences of UNESP, Botucatu Campus (SP), in the years 2014 and 2015. As the fruits of the black mulberry 'Tupy' plants were evaluated, whose seedlings were planted on 06/23/2009. Six more vigorous stems were conducted in a non-irrigated experimental area in the T-tier system with two wires and 1,2 meters in height. The spacing was 0,6 m between plants and 4,0 m between rows and the planting density of 4,166 plants ha-1. In the experiment, the experimental design was a randomized block in factorial 4 x 3, the first factor corresponding to the concentrations of calcium chloride (0, 1,5, 3 and 4,5 %) and the second to the numbers of applications (1, 2 and 3 applications). The phonological phase adopted for the first application of calcium chloride was of the green fruits at the beginning of swelling and still adhered to the flower remains. When more than one application was performed, there was an interval of five days between one application and another. Physical, physicochemical, biochemical and enzymatic evaluations were performed on the fruits. The levels of Ca+2 were measured in the leaves before and after the applications with CaCl2 and in the fruits as soon as the harvest was carried out. The application of pre-harvest CaCl2, at a concentration of 4,5 %, when fruits were in the phonological stage of fruit swelling with floral remains, promotes lower weight loss, higher firmness and ascorbic acid content in blackberries ‘Tupy’. Higher concentrations of CaCl2 promote reduction of soluble and total soluble sugars, antioxidant activity and total polyphenols.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES

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
