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
Draft genome sequence of Psychrobacter okhotskensis strain 5179-1A, isolated from a raw cured ham storage crate
Get PDFWe present the draft genome sequence of Psychrobacter okhotskensis strain 5179-1A, which was isolated from a raw cured ham storage crate. Its size and GC content are 3.4 Mb and 43.4%, respectively. The 16S rRNA sequences of strain 5179-1A and P. okhotskensis MD17T are 100% identical
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

consumo de sustancias tóxicas en adolescentes de la Institución
Educativa N° 5179 Los Pinos, Puente Piedra, Lima 2023. Método:
Se planteó una metodología con enfoque con enfoque
cuantitativo, de alcance descriptivo y diseño observacional
transversal se utilizó una población conformada por todos los
adolescentes de la Institución Educativa N° 5179 Los Pinos,
Puente Piedra, Lima, conformado por 17 secciones siendo un
total de 380 estudiantes de 12 a 18 años las cuales se analizaron
el consumo de sustancias toxicas de acuerdo al sexo,
nacionalidad, edad, dinero disponible semanal y identificar el
consumo de sustancias toxicas empleándose el instrumento de
encuesta de recolección de datos. Resultados: El análisis de
consumo de sustancias toxicas reflejo un 76,6%, no consume.
Según sexo no consumir sustancias tóxicas no hay disparidades
sustanciales en los patrones de consumo de sustancias tóxicas
entre hombres y mujeres. Según nacionalidad no muestra
relación alguna entre la nacionalidad con el consumo de ninguna
de las tres sustancias toxicas estudiadas. Según edad encontró
que no había consumo frecuente (18,4%) de sustancias tóxicas
en los adolescentes de 13 años, no había consumo frecuente
(36,8%) de sustancias tóxicas, pero sí un consumo ocasional
(6,8%). Según dinero disponible semanal aquellos con ingresos
de 1 a 5 soles y que no había consumo frecuente (94,7%) de
cannabis en los adolescentes de la Institución Educativa N° 5179.
Conclusiones: Este hallazgo refleja una tendencia hacia prácticas
de estilo de vida más saludables dentro de la Institución

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
