Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Determinación del índice de calidad de playas – BQI (Beach Quality Index) en tres playas del Atlántico (Caño Dulce, Puerto Velero y Salgar).
Full text linkLa investigación consiste en la determinación del Índice de Calidad de Playas – BQI (Beach Quality Index), en tres playas del departamento del Atlántico: Caño Dulce, Puerto Velero y Salgar. El BQI realiza una evaluación del estado de la playa a partir de las tres funciones más
importantes que ofrecen estos ecosistemas: La función recreativa, la función natural y la función
de protección; para lo que se dispone de tres subíndices que conforman el BQI, permitiendo determinar:
1. La calidad de los aspectos que componen la función recreativa de las playas como lo son la calidad microbiológica del agua, el confort, las condiciones de saturación, la calidad estética e higiénica de las playas, las facilidades y servicios que se prestan, las actividades
que afecten el disfrute de las áreas, los accesos y parqueaderos, la calidad de los
alrededores y la seguridad en las playas, a partir del Subíndice de la Función Recreativa (RFI).
2. La calidad de los aspectos que componen la función natural, dentro de los cuales se incluyen las condiciones naturales de las playas como la representatividad de especies de
flora, la cobertura vegetal y el desarrollo del hábitat; así mismo se incluyen la calidad del
agua y la arena a partir del nivel de contaminación detectado y la calidad física de la playa que determina los cambios en ciertos componentes físicos en las playas por efectos de la actividad antrópica directa. Esto determinado por medio del Subíndice de la Función Natural (NFI).
3. El grado de protección que ofrecen estas áreas, determinado por medio del Subíndice de
la Función de Protección (PFI), para lo que se evalúan aspectos como el ancho efectivo de playa que es la longitud entre la infraestructura y la línea de costa, el alcance de los temporales y el ancho mínimo de playa requerido para que proteja la infraestructura.
Como resultado de la aplicación del BQI en las tres playas del Departamento del
Atlántico, se encontró que la playa con mejor valoración fue Puerto Velero (BQI=0,56), seguida por Caño Dulce (BQI=0,53) y el valor más bajo para la playa Salgar (BQI=0,24). Respecto a los índices parciales, el valor más alto de RFI lo obtuvo Puerto Velero (0,52), mientras que el valor
de NFI fue igual para Puerto Velero y Caño Dulce (0,86) y el máximo valor de PFI lo obtuvo
Caño Dulce (0,39).
Finalmente, la determinación del BQI permite a los gestores de playas y tomadores de decisiones contar con un insumo que representa la calidad ambiental de las playas, teniendo en cuenta las tres funciones mencionadas, para determinar las medidas de ordenamiento y gestión a implementar en estas valiosas áreas.The research consists of the determination of the Beach Quality Index (BQI) on three beaches in the Atlántico department in Colombia: Caño Dulce, Puerto Velero and Salgar. The BQI carries out an assessment of the state of the beach from the three most important functions
offered by these ecosystems: The Recreational Function, The Natural Function and the
Protection Function. For which three sub-indices are arranged.
1. The quality of the aspects that make up the recreational function of beaches such as the microbiological quality of water, comfort, saturation conditions, the aesthetic and hygienic quality of the beaches, the facilities and services provided, Activities that affect
the enjoyment of the areas, the accesses and parking, the quality of the surroundings and
the security in the beaches. The recreational Quality was determined by the Recreational Function Index (RFI).
2. The quality of the aspects that make up the natural function, which include the natural conditions of beaches such as the representativeness of flora species, vegetation cover
and habitat development; Water and sand quality are also included from the level of
pollution detected and the physical quality of the beach that determines the changes in certain physical components in the beaches due to the effects of anthropic activity. The Natural Quality was determined by the Natural Function Index (NFI).
3. The degree of protection offered by these areas, for which aspects such as the effective width of beach, which is the length between the infrastructure and the coastline, the extent of the storms and the minimum beach width required for Protect the infrastructure.
Determined by the Protection Function Index (PFI).
As a result of the application of the BQI in the three beaches of the Department of the Atlantic, it was found that the beach with the best valuation was Puerto Velero (BQI=0,56), Followed by Caño Dulce (BQI = 0,53) and the lowest value by Salgar beach (BQI = 0,24).
Regarding the partial indexes, the highest value of RFI obtained Puerto Velero (0,52), while the value of NFI was equal to Puerto Velero and Caño Dulce (0,86) and the maximum value of PFI was obtained by Caño Dulce (0,39).
Finally, the determination of the BQI allows beach managers and decision makers to have an input that represents the environmental quality of beaches, taking into account the three functions mentioned, to determine the management and management measures to be
implemented in these valuable Areas.Benavides Céspedes, Julián Andrés-57ef97e6-7cc0-4c9c-9fb5-c78d7de6a189-60
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn 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.
