Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Patient Positioning and the Accuracy of Pulmonary Artery Pressure Measurements (180f)
The measurement of pulmonary artery pressure (PAP) is a common nursing practice in hemodynamic monitoring of patients in the emergency room and intensive care unit. Several researchers have proposed that PAP should be measured with the patient in a supine position with legs horizontal in order to promote a relaxed state. The most widely used reference point is the phlebostatic axis, which is located at the intersection of the fourth intercostal space and the midchest level. However, this positioning requirement is in conflict with one of the goals of nursing care, which is to achieve comfortable positioning of the patient without compromising respiratory or cardiovascular function. In addition, since frequent readings are necessary , critically ill patients can lose valuable sleep time. The existing literature still fails to justify the validity of the phlebostatic axis as an external reference point for leveling the pressure transducer. In addition, findings on the accuracy of readings obtained in the supine, Fowler's and lateral recumbent positions are also in conflict . This paper reviewed research related to measurement of PAP in the supine , various Fowler's, and lateral positions in order to clarify the major factors which might have resulted in the conflicts in data on PAP measurements. Suggestions are also provided for nurse clinicians to obtain more accurate PAP measurements. (C) 1999 Elsevier Science Ltd. All rights reserved
Triangulation in Nursing Research: Issues of Conceptual Clarity and Purpose
The controversy concerning the value of qualitative, quantitative andtriangulation approaches to nursing research for understanding human behaviour and increasing nursing knowledge has been an increasing source of debate among nurse scholars. However, the differences and similarities of these three perspectives have not been fully compared as either philosophies or methodologies. The purposes of this paper are to provide an understanding of the origin and development of the triangulation research method, clarify major sources of confusion in the presentation of a triangulation study, and discuss the problems and possible solutions of a triangulation study. Finally, an example of multiple triangulation in a nursing research within a Taiwanese cultural context - turning points of recovery from cardiac surgery during the intensive care unit transition - is presented. In the course of the paper, suggestions are also given to help nurse researchers recognize when it is most appropriate to use a certain research method, whether that be qualitative, quantitative or triangulation
Variations on the Author
“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
We 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
