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
Regulación suave desde una metaorganización: el caso de los objetivos de desarrollo del milenio
Full text linkDesde su creación, la Organización de las Naciones Unidas ha desarrollado diversos mecanismos para influir en sus Estados Miembros, Estados autónomos, con diferentes regímenes y recursos políticos. Los Objetivos de Desarrollo del Milenio (ODM), fueron uno de ellos. En México, fueron asimilados exitosamente en los procesos de formulación y evaluación de políticas de desarrollo. El propósito de esta tesina es investigar qué mecanismos específicos usó la ONU para que los ODM tuvieran efectos concretos en los procesos de políticas en México
Facticity according to the expression of uncertainty in a communicative policy instrument: tendencies in a long-duration crisis
No full textIncertidumbre, comunicación, políticas públicas, facticidad, COVID-19La expresión de incertidumbre en la comunicación usada como instrumento de política pública en una crisis es fundamental para entender la gravedad de la situación, decidir y deliberar sobre la actuación del gobierno. Al inicio de una crisis se conoce poco sobre sus causas y sobre los efectos de distintos cursos de acción por lo que los comunicadores pueden ser imprecisos en la expresión de la incertidumbre. Las imprecisiones también pueden ser producto de la doble naturaleza de un instrumento de política pública. Aunque esté basado en conocimiento científico positivista, también está sujeto a incentivos políticos y constreñido por las reglas de lo público. Las imprecisiones y diferencias entre lo que se sabe y se dice pueden producir baja facticidad en la comunicación. Es importante observar su variación través del tiempo para ampliar nuestro entendimiento. La tesis responde a la pregunta ¿Cómo se genera o disminuye la facticidad a partir de la expresión de incertidumbre en un instrumento comunicativo de política pública durante una crisis? mediante un método cuantitativo híbrido con análisis de texto como datos. Contribuye a la literatura sobre uso de instrumentos comunicativos de política pública con una teoría tipológica sobre la facticidad en la expresión de incertidumbre durante crisis. También aporta empíricamente con un diccionario para R sobre lenguaje de incertidumbre y con el caso de México. Se trata de un país cuyo gobierno favoreció un sesgo hacia la ignorancia de la magnitud real de las infecciones por COVID-19 y cuya respuesta inicial fue imprudente. La crisis obligó a los comunicadores a ser más precisos sobre la incertidumbre en los momentos más sorpresivos y peligrosos y a cambiar de estrategia una vez que comenzó la distribución de vacunas.The expression of uncertainty in communication which is used as a public policy instrument during a crisis is fundamental to understanding the severity of the situation, deciding, and deliberating. At the beginning of a crisis, little is known about its causes and the effects different courses of action may have, so communicators may be imprecise in expressing uncertainty. These imprecisions can also result from the dual nature of a public policy instrument. Although it may be based on positivist scientific knowledge, it is also subject to political incentives and is constrained by public rules. The imprecisions and differences between what is known and what is said can produce low factuality in communication. It is important to observe its variation over time to broaden our understanding. The dissertation answers the question: How is factuality generated or diminished through the expression of uncertainty in a communicative public policy instrument during a crisis? It answers through a hybrid quantitative method with text as data. This dissertation contributes to the literature on the use of communicative public policy instruments with a typological theory on factuality in the expression of uncertainty. It also provides empirical contributions with a dictionary for R on uncertainty language in Spanish, and with the case of Mexico. This is a country whose government favored a bias towards ignorance of the real magnitude of COVID-19 infections and whose initial response was imprudent. The crisis forced communicators to be more precise about uncertainty in the most surprising and dangerous moments and to change strategy once vaccine distribution began
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
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
