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
Estimación del nivel de Seguridad Alimentaria en estudiantes universitarios, Santo Domingo 2019
No full textThe problem raised was the lack of knowledge of the level of food security in college students of Santo Domingo; hence the goal was to find an index that estimates the level of food safety in these students. Reading on the subject, established the concept of food security and the factors that determined it. Armed these theoretical foundations and methods of collection and analysis of information, in particular, Likert scales and elements of statistical inference, was recollected and process primary information of a survey, a sample of college students. The most outstanding results were, the construction of a reliable and valid measurement instrument, which can be used in other works, the obtaining of information directly from the people involved, not by indirect methods as is often done, and the food safety index of University students. Finally, anissue that draws attention to analyzing the results of the survey is that students showed doubts by checking in raised claims, which warns in the high frequency of the neutral category. This is made more manifest in that category in the case of the third statement on the nutritional quality of the food.El problema que se planteó fue el desconocimiento del nivel de seguridad alimentaria en los estudiantes universitarios de Santo Domingo, de aquí que el objetivo trazado haya sido encontrar un índice que estime el nivel de seguridad alimentaria en dichos estudiantes. De la lectura sobre el tema, se estableció el concepto de seguridad alimentaria y los factores que determinaban la misma. Armados de estos fundamentos teóricos y de los métodos de obtención y análisis de la información, en particular, de las escalas de Likert y elementos de inferencia estadística, se recabó y procesó la información primaria de una encuesta, a una muestra de estudiantes universitarios. Los resultados más sobresalientes fueron, la construcción de un instrumento de medición confiable y válido, que puede ser usado en otros trabajos, la obtención de la información directamente de las personas implicadas, no por métodos indirectos como se suele hacer frecuentemente, además se estimó el índice de seguridad alimentaria de los estudiantes universitarios. Por último, una cuestión que llama la atención al analizar los resultados de la encuesta, es que los estudiantes presentaron dudas al marcar en las afirmaciones planteadas, lo cual se advierte en la elevada frecuencia de la categoría neutro. Esto se hace más manifiesto en dicha categoría en el caso de la tercera afirmación relativa a la calidad nutricional de la alimentación
Índice de calidad de la asistencia médica según la percepción de estudiantes universitarios, Santo Domingo 2019
Get PDFThe addressed problem was the lack of an index that quantifies the quality of health care from the perspective of the users. The objective is, therefore, the obtaining of this index. As a matter of first broke it existing in the literature theory to establish the concepts of medical care and its quality, and dimensions that make it up. From here was an instrument of measuring type Likert scale, based on the dimensions of the concept of health care, which was applied to a group of 54 University students, selected as a random sample with a precision of 1% and 95% reliability. The processing of the data confirmed. On the one hand, the reliability of the scale and, secondly, threw the following estimates of the dimensions: availability 70.74 %, accessibility 75,18 %, acceptability 57,40 %; and the quality of medical care index67,77 %.If as defined, a level of 75 % falls into the category of good and a level of 50 % on the regular, these results are perceptions closer to the category of good, except the dimension of acceptability, which denotes dissatisfaction in the service and may be tem a particular scrutiny.El problema abordado fue el desconocimiento de un índice que cuantifique la calidad de la asistencia médica desde la perspectiva de los usuarios. El objetivo es, por tanto, la obtención de dicho índice. Como primera cuestión se partió de la teoría existente en la bibliografía consultada para establecer los conceptos de asistencia médica y su calidad, y de las dimensiones que la conforman. A partir de aquí se elaboró un instrumento de medición tipo escala de Likert, en base a las dimensiones del concepto de asistencia médica, que fue aplicado a un grupo de 54 estudiantes universitarios, seleccionados como una muestra aleatoria con precisión de 1 % y confiabilidad 95 %. El procesamiento de los datos confirmó, por una parte, la confiabilidad de la escala y, por otra, arrojó las siguientes estimaciones de las dimensiones: disponibilidad 70.74 %, accesibilidad 75,18 %, aceptabilidad 57,40 %; y del índice de calidad de la asistencia médica 67,77 %. Si como se definió, un nivel del 75 % cae en la categoría de bueno y un nivel de 50 % en la de regular, estos resultados ubican las percepciones más cercanas a la categoría de bueno, exceptuando la dimensión de aceptabilidad, que denota inconformidad en el servicio y puede ser tema de un escrutinio particular
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
