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
Foundational Development of Emergence
Get PDFAbstract: This paper presents a non-standard approach to emergence that describes the foundational stages of the development of emergence, including the factors that initiate the progressive stages of its development. Observing that emergence is a naturally occurring creative process in the universe, the focus of the paper is a strictly realist analysis of the intrinsic qualities of emergence. Emergence brings things into existence, things such as objects, qualities, relations, and systems. The process of emergence develops, becoming increasingly complex as additional factors come to play roles in the process. The paper describes a diagram of the foundational stages of the development of emergence that shows what additional factors initiate the progressive stages of its development. The diagram displays the origins of factors such as the contact relation and the cause relation, among others. Factors that originate in the stages of the foundational development of emergence play roles in the forms of emergence that occur in highly complex situations like geology, biology, sociology, ecology, and cosmology. Understanding the foundational stages of emergence can enhance understanding in all the disciplines. The paper explains how emergence is a component of science based transdisciplinarity. It presents a new paradigm for understanding the intrinsic nature of emergence. The intention is to make the understanding of emergence useful by way of a strictly realist approach based on observation. The goal is to provide scientists with a practical method for the identification and mapping of emergence in systems of interest
From Bertalanffy to Discipline-Independent-Transdisciplinarity
Get PDFWhen Bertalanffy advocated a new scientific discipline called general system theory, this generalist mode of understanding was to be based on the isomorphism of laws, principles, and models in the different sciences, and on structural uniformities (isomorphies) in the subject matters of those sciences. There is a conceptual shift in Bertalanffy’s work from the logico-mathematical mode to a deeper more complex understanding. There is a corresponding shift in the understanding of isomorphies from the isomorphy of laws and principles to the isomorphy of qualities of real systems. The recognition of isomorphies in real situations and systems has resulted in the creation of the modern generalist mode of understanding and from there the development of discipline-independent-transdisciplinarity. This paper gives an introduction to this form of transdisciplinarity, and explains how this mode of understanding naturally develops a universal transdisciplinary language
The Basis of Time in the Universe
Get PDFThis paper provides the answers to three questions about time. What is time? Why does time occur? And why does time have the specific intrinsic qualities that it has? The answers are based on the recognition that the continuing-existence of space plays the roles in the universe that are normally attributed to time. This recognition is based on objective observation of space itself and objective observation of the continuing-existence of space. The methodology of the observations and the conclusions do not contain speculation—no assumptions, hypotheses, or theories. Objective observation leads to the understanding of the intrinsic nature of space and the continuing-existence of space. Understanding the intrinsic nature of space and its continuing-existence leads to recognition of the roles space and its continuing-existence play in the universe. It then becomes evident that the roles of the continuing-existence of space are the roles of time in the universe
Foundational Origins of Change in the Universe
Get PDFThe universe is continuously new due to the roles of seven omnipresent sources of change. These foundational sources of change are here identified and described. While each source of change is unique, they each initiate change in the form of noncoexistent-sequential-difference, which is the core characteristic of change. The occurrence of noncoexistent-sequential-difference, the occurrence of change, initiates the existence of something new. Each unique source of change initiates a unique form of newness. These sources of change, and the different manners in which their change occurs as noncoexistent-sequential-difference, and the forms of newness they initiate, are interrelated due to existential-context, existential-dependency, factor development, and deep-structure. Complex forms of change, such as plate tectonics, biological evolution, the development of culture, and stellar evolution, are based on the seven foundational forms of change together interrelating with diverse other factors
