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
Métodos de poda y raleo en plantaciones adultas de Myrciaria dubia MC Vaugh H.B.K. camu-camu en suelo inundable, Santa Rosa, Belén, 2016
No full textEl presente trabajo de investigación se llevó a cabo en la comunidad de Santa Rosa, Río Amazonas, distrito de Belén, entre las coordenadas 03º42’24.0” latitud Sur y 73º11’01.5” de longitud Oeste, la zona se encuentra ubicada en una terraza baja inundable. Con el objetivo de determinar técnicas de poda de producción y raleo de plantas para recuperar la capacidad productiva en plantaciones adultas de camu-camu en suelo inundable, se intervino a una plantación de 20 años de edad y con distanciamientos de 3 x 2 m. El experimento se instaló sin delineamiento experimental (Marcos Vilela 2007), Modelo 58, donde se estudiaron 4 tratamientos incluyendo el testigo con 8 repeticiones, T1 “testigo” (sin poda-sin raleo), T2 (sin poda-con raleo por línea), T3 (con poda-con raleo por línea), T4, (con poda-con raleo selectivo). Las variables respuesta fueron: “numero de flores/planta” (NFL), “número de frutos en fase 3” (NFRF3), “número de frutos en fase 5” (NFRF5), “porcentaje de frutos caídos en fase 3” (%FRCF3), “porcentaje de frutos caídos en fase 5” (%FRCF5), “peso promedio de fruto” (PPFR) y “rendimiento de frutos” (RFR). Los datos obtenidos se procesaron mediante el programa estadístico INFOSTAT versión 2016e, se realizó análisis de variancia no paramétrica de Kruskal-Wallis y prueba de medianas para: NFL, NFRF3, NFRF5, y RFR, con valores de (p=0.0002), (p=0.0022), (p=0.0009) y (p=0.0010), las cuales presentan diferencias significativas, y diferencias no significativas para PPFR (p=0.5793). ANVA y prueba de Tukey para %FRCF3 (p=0.0009) y %FRCF5 (p=0.2449), donde el T2 alcanzo valores superiores en todas estas variables. En los once meses del ensayo, se pudo observar que el T2 (sin poda-con raleo por línea) logró el mayor rendimiento de frutos, el raleo por línea mejoró el desarrollo de las plantas por mayor disponibilidad de luz, espacio y nutrientes, lo cual se vio reflejado en una mayor producción de flores y frutos. El testigo T1, presentó el menor rendimiento de frutos. Quedó evidenciado que la poda aunque fue superficial redujo el rendimiento de frutos.The present research work was carried out in the community of Santa Rosa, Amazonas River, district of Belén, between the coordinates 03º42'24.0 "South latitude and 73º11'01.5" West longitude, the zone is located in a low terrace Floodable. With the objective of determining pruning techniques of production and stand-thinning of plants to recover the productive capacity in adult plantations of camu-camu in floodable soil, a plantation of 20 years of age and with distances of 3 x 2 m was intervened. The experiment was installed without experimental design (Marcos Vilela 2007), Model 58, where 4 treatments were studied, including the control with 8 repetitions, T1 “control”, (without pruning-without stand-thinning), T2 (without pruning with stand-thinning per line), T3 (with pruning and stand-thinning per line), and T4 (with pruning and selective stand-thinning). The response variables were: "number of flowers / plant" (NFL), "number of fruits in phase 3" (NFRF3), "number of fruits in phase 5" (NFRF5), % FRCF3), "percentage of fallen fruits in phase 5" (% FRCF5), "average fruit weight" (PPFR) and "fruit yield" (RFR). The data obtained were processed using the statistical program INFOSTAT version 2016e, with Kruskal-Wallis non-parametric variance analysis and median test for: NFL, NFRF3, NFRF5, and RFR, with values of (p = 0.0002), (p = 0.0022), (p = 0.0009) and (p = 0.0010), which presented significant differences, and non-significant differences for PPFR (p = 0.5793). ANVA and Tukey's test for% FRCF3 (p = 0.0009) and% FRCF5 (p = 0.2449), where T2 reached higher values in all these variables. The data obtained were processed using the statistical program INFOSTAT version 2016e, was performed analysis of Kruskal-Wallis non-parametric variance and median test for: NFL, NFRF3, NFRF5, and RFR, with values of (p = 0.0002), (p (P = 0.0009) and (p = 0.0010), which presented significant differences, and non-significant differences for PPFR (p = 0.5793). ANVA and Tukey test for %FRCF3 (p = 0.0009) and %FRCF5 (p = 0.2449), where T2 reached higher values in all these variables. In the eleven months of the investigation, it was observed that T2 (without pruning-with stand-thinning per line) achievement the highest yield of fruits, thinning per line improved the development of plants by greater availability of light, space and nutrients, Which was reflected in a higher production of flowers and fruits. The control T1 presented the lowest fruit yield. It was evidenced that pruning, although superficial, reduced fruit yield.Tesi
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
